The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

Herein, ordinal numbers such as “first” and “second” cited in this application are merely identifications and do not have any other meanings, such as a specific order or the like.

In order to thoroughly understand the implementation of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present application is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the present application is described in detail below, but in addition to these detailed descriptions, the present application may also have other implementations.

The present application provides a drilling device that can be used to drill holes in a floor 220 laid on a chassis of a container, so that the floor 220 can be fixedly connected to the chassis.

Please refer to Figures 1 to 7, the drilling equipment includes a drilling device. The drilling device includes a drill frame 110, a lifting guide column 120, a lifting frame 130 and a drill assembly 140. The drill frame 110 can be set on the vehicle body 190 described later to move with the vehicle body 190. The drill frame 110 is provided with a first lifting hole 113. The axial direction of the lifting guide column 120 is parallel to the lifting direction (when the drilling equipment is drilling, the lifting direction is parallel to the vertical direction). The lifting guide column 120 is inserted into the first lifting hole 113. The lifting guide column 120 is movably arranged relative to the drill frame 110 along the lifting direction.

The lifting frame 130 is connected to the lifting guide column 120. In this way, the lifting frame 130 and the lifting guide column 120 move together. That is, along the lifting direction, the lifting frame 130 is movably (upward or downward) arranged relative to the drill frame 110. In this process, the setting of the lifting guide column 120 penetrating the second lifting hole 133 can guide the lifting of the lifting frame 130. In addition, the setting of the lifting guide column 120 penetrating the second lifting hole 133 can improve the force of the lifting frame 130 when drilling, and reduce the possibility of damage to the connection between the lifting drive assembly 170 and the drill frame 110 described later.

The drill assembly 140 includes a drill 146. The drill 146 is used to drill a hole on the floor 220 of the container. The drill assembly 140 is disposed on the lifting frame 130. At this time, the axial direction of the drill 146 is parallel to the lifting direction.

When the lifting frame 130 moves in the lifting direction, it can drive the drill assembly 140 to move in the lifting direction. In this way, when the drill bit 146 rotates, the drill bit 146 can be moved in the lifting direction, thereby drilling a hole on the floor 220.

Please refer to Figures 1, 2 and 5, the drilling device also includes a depth positioning assembly 150. The depth positioning assembly 150 includes a depth positioning member 151 and a lifting sensor (not shown). The depth positioning member 151 is arranged on the lifting frame 130. Along the lifting direction, the depth positioning member 151 is movably arranged relative to the lifting frame 130. Along the lifting direction, the depth positioning member 151 is located on the upper side of the free end of the drill bit 146. When the drill bit 146 drills into the floor 220 to a certain depth, the depth positioning member 151 contacts the floor 220 of the container. When the drill bit 146 continues to drill into the floor 220, the action of the floor 220 on the depth positioning member 151 causes the depth positioning member 151 to move upward relative to the drill bit 146.

Preferably, the depth positioning assembly 150 is located on the side of the drill bit 146. Thus, the structure of the drilling device is simple.

The lifting sensor may be a position switch. The lifting sensor is disposed on the lifting frame 130. The lifting sensor is located directly above the depth positioning assembly 150. When the upper end of the depth positioning member 151 moves to the lifting limit position, the depth axis 155 described later can trigger the lifting sensor. At this time, the lifting sensor can sense the lifting limit signal indicating that the upper end of the depth positioning member 151 moves to the lifting limit position.

Referring to FIGS. 1 to 9 , the drill head device further includes a controller 210. The drilling device further includes a lifting drive assembly 170. The lifting drive assembly 170 may be a cylinder. The cylinder shaft of the lifting drive assembly 170 is connected to the lifting top wall of the lifting frame 130. The cylinder seat of the cylinder is connected to the drill head frame 110. The cylinder is used to drive the lifting frame 130 to move relative to the drill head frame 110 along the lifting direction.

The controller 210 is electrically connected to the lifting drive assembly 170 and the lifting sensor. When the controller obtains the lifting limit signal through the lifting sensor, it means that at the current moment, the drilling depth of the drill bit 146 is the preset drilling depth value. At this time, the controller 210 controls the action of the lifting drive assembly 170, so that the lifting frame 130 moves upward to make the drill bit 146 leave the floor 220.

The preset drilling depth value and the position of the lifting sensor along the lifting direction are set correspondingly. The staff can adjust the drilling depth by adjusting the position of the lifting sensor along the lifting direction.

In this embodiment, the drill frame 110 is provided with a first lifting hole 113, the lifting guide column 120 is inserted into the first lifting hole 113, and the lifting frame 130 is connected to the lifting guide column 120. In this way, the setting of the lifting guide column 120 inserted into the second lifting hole 133 can guide the lifting of the lifting frame 130; in addition, the setting of the lifting guide column 120 inserted into the second lifting hole 133 can improve the force applied to the lifting frame 130 during drilling, and reduce the possibility of damage to the connection between the lifting drive assembly 170 and the drill frame 110 described later; in addition, the depth positioning member 151 is movably arranged relative to the lifting frame 130, and can be used to detect the drilling depth of the drill bit. When the drilling depth is the preset drilling depth, the controller can control the operation of the lifting drive assembly to move the lifting frame 130 upward, thereby causing the drill bit 146 to leave the floor 220 and automatically complete the drilling.

Preferably, referring to FIGS. 1 to 4 , the drill frame 110 includes a first lifting portion 112. The first lifting portion 112 includes a drill top wall, a drill bottom wall, two drill side walls 114 and a drill end wall. The drill top wall and the drill bottom wall are arranged in parallel and spaced apart along the lifting direction. The two drill side walls 114 are arranged in parallel and spaced apart along the length direction of the drill frame 110. The plane where the drill end wall is located is perpendicular to the width direction of the drill frame 110. The plane where the drill side wall 114 is located is perpendicular to the length direction of the drill frame 110. The plane where the drill top wall is located and the plane where the drill bottom wall is located are both perpendicular to the lifting direction.

The drill head top wall, the drill head bottom wall, the two drill head side walls 114 and the drill head end wall form a generally rectangular structure with one end open. The drill head frame 110 also includes a bracket mounting portion 111. The bracket mounting portion 111 is connected to the first lifting portion 112. The bracket mounting portion 111 is used to be mounted to the vehicle body 190 described later.

Please continue to refer to Figures 1 to 4. The lifting frame 130 includes a second lifting part 132. The second lifting part 132 includes a lifting top wall, a lifting bottom wall, two lifting side walls 134 and a lifting end wall. The lifting top wall and the lifting bottom wall are parallel and spaced along the lifting direction. The two lifting side walls 134 are parallel and spaced along the length direction of the lifting frame 130. The plane where the lifting end wall is located is perpendicular to the width direction of the lifting frame 130. The plane where the lifting side wall 134 is located is perpendicular to the length direction of the lifting frame 130. The plane where the lifting top wall is located and the plane where the lifting bottom wall is located are both perpendicular to the lifting direction. The lifting top wall, the lifting bottom wall, the two lifting side walls 134 and the lifting end wall form a roughly rectangular structure with one end open. The drill head top wall and the drill head bottom wall of the first lifting part 112 are both provided with a first lifting hole 113. The lifting guide column 120 is penetrated through the first lifting hole 113 of the drill head top wall and the first lifting hole 113 of the drill head bottom wall.

When the lifting frame 130 and the drill frame 110 are connected by the lifting guide column 120, the length direction of the lifting frame 130 is parallel to the length direction of the drill frame 110, and the width direction of the lifting frame 130 is parallel to the width direction of the drill frame 110. The drill end wall of the first lifting part 112 and the lifting end wall of the second lifting part 132 are parallel and spaced apart. The lifting top wall and the lifting bottom wall of the second lifting part 132 are both provided with a second lifting hole 133. The lifting guide column 120 is penetrated in the second lifting hole 133. The lifting guide column 120 is fixedly connected to the lifting top wall and the lifting bottom wall of the lifting frame 130. As a result, the strength of the first lifting part 112 and the second lifting part 132 is large.

Part of the first lifting part 112 is located in the second lifting part 132. Specifically, the drill head top wall, the drill head bottom wall and the drill head side wall 114 are all located in the second lifting part 132. Part of the drill head end wall is located in the second lifting part 132. The surface of the drill head end wall away from the opening of the first lifting part 112 is located outside the second lifting part 132. As a result, the overall structure of the first lifting part 112 and the second lifting part 132 is compact.

As shown in FIG3 , there are a plurality of (e.g., two) lifting guide posts 120. The plurality of lifting guide posts 120 are spaced apart along the length direction of the lifting frame 130. Thus, the lifting frame 130 moves smoothly relative to the drill frame 110 in the lifting direction. The lifting frame 130 cannot rotate around the axis of the lifting guide posts 120.

As shown in FIGS. 3 and 4 , the drilling device includes a bearing 160. The bearing 160 may be a graphite linear sleeve. The bearing 160 is inserted into the first lifting hole 113. The top wall and the bottom wall of the drill head of the drill head frame 110 are both provided with bearings 160. The bearing 160 is sleeved on the lifting guide column 120. As a result, the lifting guide column 120 moves smoothly relative to the drill head frame 110.

As shown in FIG3 , one drill side wall 114 of the first lifting part 112 is located on the inner side of the first lifting side wall 134 close to the second lifting side wall 134 and close to the first lifting side wall 134 (along the length direction of the lifting frame 130, the distance between the drill side wall 114 and the adjacent lifting side wall 134 ranges from 1 mm to 5 mm). The other drill side wall 114 of the first lifting part 112 is close to the inner side of the second lifting side wall 134. Thus, the first lifting part 112 can prevent the second lifting part 132 from rotating.

Please return to Figures 1 and 2. The drill assembly 140 also includes a drill motor 141 (servo motor), a reducer 142, a coupling 143, a rotating shaft 144, a drill chuck 145 and a drill bit 146. The lifting frame 130 also includes a drill mounting portion 131. The drill mounting portion 131 is connected to the second lifting portion 132. The housing of the drill motor 141 is connected to the housing of the reducer 142. The housing of the reducer 142 is connected to the drill mounting portion 131. The output shaft of the drill motor 141 is connected to the input shaft of the reducer 142. The output shaft of the reducer 142 is connected to one end of the coupling 143. The other end of the coupling 143 is connected to one end of the rotating shaft 144. The other end of the rotating shaft 144 is connected to the drill chuck 145. The drill chuck 145 can be a drill chuck for clamping the drill bit 146 of the prior art. The drill bit 146 can be a twist drill. The tail portion of the drill bit 146 is connected to the drill chuck 145 .

Among them, the axial direction of the coupling 143, the axial direction of the output shaft of the reducer 142, the axial direction of the rotating shaft 144, and the axial direction of the drill bit 146 are all parallel to the lifting direction.

Please refer to FIG. 1, FIG. 2, FIG. 6 and FIG. 7, the drill assembly 140 further includes a reaming knife 147. The reaming knife 147 is sleeved on the drill bit 146. Along the lifting direction, the lower end of the reaming knife 147 is located above the lower end of the drill bit 146. The axis of the reaming knife 147 coincides with the axis of the drill bit 146. When the drill bit 146 drills a hole on the floor 220, when the drill bit 146 enters the floor 220 to the reaming depth, the reaming knife 147 begins to expand the hole drilled by the drill bit 146. During the drilling process, along the axial direction of the drill bit 146, the position of the reaming knife 147 relative to the drill bit 146 is fixed.

The position of the reamer 147 relative to the drill bit 146 is adjustable along the axial direction of the drill bit 146. Thus, the position of the reamer 147 relative to the drill bit 146 along the axial direction of the drill bit 146 can be adjusted as needed, thereby adjusting the depth of the reamer 147 reaming.

As shown in Figures 6 and 7, the drill bit assembly 140 also includes a connecting sleeve 148 and an elastic fixing member 149. The elastic fixing member 149 can be a metal member. The elastic fixing member 149 is sleeved on the outer periphery of the drill bit 146. The elastic fixing member 149 has an elastic through hole and a notch 224 connected to the elastic through hole. Along the axial direction of the elastic through hole, the notch 224 passes through the elastic fixing member 149. Two first positioning surfaces 221 are provided on the outer peripheral surface of the elastic fixing member 149. The two first positioning surfaces 221 are parallel and spaced apart. One first positioning surface 221 is located on one side of the notch 224. The other first positioning surface 221 is located on the other side of the notch 224.

The connecting sleeve 148 has a connecting through hole, and a first positioning hole 226 whose axial direction is perpendicular to the axial direction of the connecting through hole. The first positioning hole 226 is connected to the connecting through hole. The first positioning hole 226 is a threaded hole. There are multiple first positioning holes 226 (for example, four). Around the axis of the connecting through hole, multiple first positioning holes 226 are evenly and spaced apart. The portion of the connecting through hole forms two third positioning surfaces 223. The two third positioning surfaces 223 are parallel and spaced apart. The third positioning surface 223 is perpendicular to the radial direction of the connecting through hole. One third positioning surface 223 is correspondingly arranged on one first positioning surface 221. Another third positioning surface 223 is correspondingly arranged on another first positioning surface 221.

The elastic fixing member 149 is inserted into the connecting through hole. At this time, the third positioning surface 223 is parallel to and faces the corresponding first positioning surface 221. In this way, the connecting sleeve 148 can rotate around the axis of the connecting through hole together with the elastic fixing member 149.

The drill bit 146 is inserted into the elastic through hole. The drilling device further includes a screw. The screw is threadedly connected to the first positioning hole 226. The screw can be pressed against the outer peripheral surface of the elastic fixing member 149 to deform the elastic fixing member 149, thereby reducing the inner diameter of the elastic through hole of the elastic fixing member 149, and then the elastic fixing member 149 can hold the drill bit 146 tightly. In this way, the elastic fixing member 149 can rotate together with the drill bit 146.

The connecting sleeve 148 has a second positioning hole 227 whose axial direction is perpendicular to the axial direction of the connecting through hole. The second positioning hole 227 is connected to the connecting through hole. Along the axial direction of the connecting through hole, the second positioning hole 227 and the first positioning hole 226 are separated. The root of the reaming knife 147 is penetrated in the connecting through hole. The screw can be penetrated in the second positioning hole 227 and then abutted against the outer peripheral surface of the reaming knife 147. In this way, the reaming knife 147 can be blocked from moving relative to the connecting sleeve 148 along the axial direction of the connecting through hole.

Part of the outer peripheral surface of the reaming knife 147 forms two second positioning surfaces 222. The two second positioning surfaces 222 are parallel and spaced apart. The second positioning surfaces 222 are perpendicular to the radial direction of the reaming knife 147. One second positioning surface 222 is correspondingly arranged at a third positioning surface 223. Another second positioning surface 222 is correspondingly arranged at another third positioning surface 223. When the root of the reaming knife 147 is inserted into the connecting through hole, the second positioning surface 222 is parallel to and faces the corresponding third positioning surface 223. In this way, the reaming knife 147 and the connecting sleeve 148 can rotate together around the axis of the connecting through hole.

If the relative position between the reaming knife 147 and the drill bit 146 along the lifting direction needs to be adjusted, the screw connected to the second positioning hole 227 can be loosened, and then the relative position between the reaming knife 147 and the drill bit 146 along the lifting direction can be adjusted, and then the screw connected to the second positioning hole 227 can be tightened. In this way, the relative position between the reaming knife 147 and the drill bit 146 along the lifting direction can be adjusted conveniently.

Returning to FIG. 5 , the depth positioning assembly 150 further includes a first depth sleeve 152, a second depth sleeve 153, a depth spring 154, and a depth shaft 155. A first depth hole 156 is disposed at one end of the first depth sleeve 152. A second depth hole 157 is disposed at the second depth sleeve 153. The second depth sleeve 153 is disposed at the drill bit mounting portion 131. In this way, the second depth sleeve 153 can be lifted and lowered together with the lifting frame 130.

The second depth sleeve 153 is connected to the end of the first depth sleeve 152 away from the first depth hole 156. In this way, the first depth sleeve 152 and the second depth sleeve 153 form a depth accommodation cavity 158. The first depth hole 156 and the second depth hole 157 are both connected to the depth accommodation cavity 158. The depth shaft 155 is penetrated through the first depth hole 156 and the second depth hole 157. A step portion 159 is provided at one end of the depth shaft 155 close to the first depth hole 156. The step portion 159 is located in the depth accommodation cavity 158. The depth positioning member 151 is connected to the lower end of the depth shaft 155. The depth positioning member 151 is located on the side of the first depth sleeve 152 away from the second depth sleeve 153.

The depth spring 154 may be a cylindrical spring. The depth spring 154 is disposed in the depth accommodation cavity 158, and the depth spring 154 is sleeved on the depth shaft 155. One end of the depth spring 154 abuts against the second depth sleeve 153. The other end of the depth spring 154 abuts against the step portion 159 of the depth shaft 155.

When the floor 220 acts on the depth positioning member 151 to move the depth positioning member 151 upward relative to the drill bit 146, the depth positioning member 151 drives the depth shaft 155 to move upward, so that the depth spring 154 is in a compressed state. The depth spring 154 in a compressed state can apply a force to the step portion 159 to move the depth shaft 155 downward. In this way, when the depth positioning member 151 leaves the floor 220, the depth spring 154 can automatically reset the depth positioning member 151. In addition, during the drilling process, the depth spring 154 can press the depth positioning member 151 against the floor 220.
