The area around the drill bit 221 is protected by the protective part to ensure the safety of drilling. Further, during the drilling process, the drill head 22 and the protective part first move together and then move relative to each other. When the drill bit 221 of the drill head 22 initially drills (that is, just after drilling the ground surface), the protective part will contact the ground and contact the ground. The ground and the support frame together form a drilling protection area. At this time, the drill head 22 can continue to move downward relative to the protection part to achieve further drilling operations, and the relative movement of the two is buffered through the buffer part 40 to ensure the reliability of the drilling device. sex.

Specifically, when placing the drilling device, due to the undulations and unevenness of the ground surface at some construction sites, the ground heights of multiple support positions may be inconsistent, which will lead to unstable installation of the drilling device and affect the drilling of the drill bit. angles and drilling effects. By making the relative positions of the frame body 12 relative to multiple support positions adjustable, the adjustment of the frame body 12 is facilitated. The adjustment process includes: when the ground heights of the multiple support positions are inconsistent, adjusting the height of the ground where they are located. The relative distance between the lower support position and the frame 12 increases, until the bottom of the frame 12 corresponding to the support position is flush with the bottom of the frame 12 corresponding to the highest support position on the ground. level, realizing the adjustment of the frame body 12 and the drill head 22 provided on the frame body 12, ensuring the vertical drilling of the drill bit 221 and the reliability of the installation of the drilling device. After the adjustment is completed, the locking assembly 11 is used to lock the relative movement between the support positions of the frame 12 and the base 13 to prevent the two from self-adjustment due to vibration or other factors during the drilling process, causing the drilling device to shift. , the drilling angle deviates to ensure the reliability of drilling.

As shown in 1, the support frame 10 also includes a rotating disk 14 and an adjusting screw rod 15 for adjusting the relative positions of the support positions of the frame body 12 and the base 13 in the vertical direction. The rotating disk 14 is sleeved on the adjusting screw rod 15. The outer circumference of the frame 12 is limitedly matched with the base 13. The frame 12 has an internal threaded hole on one side facing the base 13. One end of the adjusting screw 15 is rotatably installed in the base 13, and the other end of the adjusting screw 15 is installed in the base 13. The locking assembly 11 passes through the rotating disk 14 and cooperates with the base 13 stop to limit the rotation of the rotating disk 14 and the adjusting screw rod 15 .

In this embodiment, one end of the adjusting screw rod 15 is rotatably installed on the base 13 through a bearing assembly. The other end of the adjusting screw rod 15 has an external thread and protrudes upward from the base 13 . The external thread of the adjusting screw rod 15 It is threadedly connected to the internal threaded hole at the bottom of the frame 12 located above the base 13 . When the frame 12 needs to be adjusted, the operator can rotate the rotating disk 14, and the rotating disk 14 drives the adjusting screw 15 to rotate, thereby adjusting the relative distance between the supporting positions of the frame 12 and the base 13. After the adjustment is completed, the locking assembly 11 It is in contact with the base 13 to limit the rotation of the rotating disk 14 and the adjusting screw 15 through the friction between them, so as to realize the locking of the rotation adjustment.

It can be understood that the above is a description of the adjustment of the relative position of the frame 12 and one of the support positions in the vertical direction. The frame 12 has multiple transfer positions corresponding to the multiple support positions. The support positions and transfer positions There are at least two groups. The transfer position and the support position of the same group are equipped with an adjustment screw 15 and other adjustment components for adjusting the relative positions of the two in the vertical direction. Each group of transfer positions and Locking components 11 are provided between the support positions.

As shown in Figures 1 and 3, the base 13 has an annular limiting groove 131 on one side facing the frame 12, and the rotating disk 14 has an annular limiting protrusion 141 that penetrates the annular limiting groove 131. The annular limiting protrusion The opening 141 has a placement cavity 142 connected with the annular limiting groove 131. The locking component 11 is partially disposed in the placement cavity 142 and movably extends out of the opening of the placement cavity 142. The annular limiting groove 131 corresponds to the opening of the placement cavity 142. The inner wall of one side has a friction layer 132, and the part of the locking component 11 that penetrates the placement cavity 142 is detachably friction-fitted with the friction layer 132.

In this embodiment, the limiting cooperation between the annular limiting groove 131 and the annular limiting protrusion 141 is beneficial to the installation of the rotating disk 14 and the guidance and limiting of the rotation of the rotating disk 14 . By providing the friction layer 132, and through the contact friction between the locking component 11 and the friction layer 132, the rotation of the rotating disk 14 is restricted, ensuring the locking of the adjusted frame 12 and the drilling part 20.

Specifically, after completing the adjustment of the frame body 12 and the drilling part 20 , the operator moves the partial locking assembly 11 that is disposed in the placement cavity 142 so that the partial locking assembly 11 extends out of the placement cavity 142 The opening is in contact with the friction layer 132 and is close to the friction layer 132. Since during the adjustment process of the frame body 12 and the drilling part 20, the locking component 11 will rotate with the rotating disk 14, so when the locking component 11 and the friction layer When 132 is in contact and close to each other, the rotation of the locking component 11 is restricted, thereby limiting the rotation of the rotating disk 14 and the adjusting screw 15 .

As shown in Figure 3, the locking assembly 11 includes a rotating shaft 111 and a movable block group. The rotating shaft 111 is rotatably installed in the rotating plate 14. One end of the rotating shaft 111 is installed in the placement cavity 142 and has an external thread. The movable block group is arranged in the placement cavity 142 and is limitedly matched with the inner wall of the placement cavity 142. The movable block group has an internal thread hole, and the rotating shaft 111 is threadedly connected to the movable block group to drive the movable block group in the placement cavity 142. The opening of the placement cavity 142 is moved and extended to contact the friction layer 132 .

In this embodiment, the rotating shaft 111 is rotatably inserted into the rotating plate 14 through the bearing assembly. The rotating shaft 111 can only be rotated but not moved. After the adjustment of the frame body 12 and the drilling part 20 is completed, The operator rotates the rotating shaft 111 so that the movable block group in the placement cavity 142 moves toward the friction layer 132 until the movable block group contacts the friction layer 132 to limit the rotation of the rotating disk 14 and the adjusting screw 15 . With this arrangement, the movement of the movable block group is driven by the rotating shaft 111, and after the movable block group and the friction layer 132 come into contact and fit, the two are pressed tightly together to ensure the reliability of friction to prevent rotation. Specifically, when it is necessary to adjust the frame body 12 and the drilling part 20, it is only necessary to rotate the rotating shaft 111 in the opposite direction so that the driving force and pressing force on the movable block group are reduced or eliminated, and the movable block group and the friction layer 132 No longer close to each other or separated, the friction between the two is not enough to stop the rotation, and then the rotating disk 14 and the adjusting screw 15 can be rotated to realize the adjustment of the frame 12.

Specifically, the placement cavity 142 includes a first cavity segment and a second cavity segment with an included angle in the extension direction. The opening of the second cavity segment is connected with the annular limiting groove 131 and faces the friction layer 132. The movable block group includes a pushing block 112 and a The stop block 113 and the push block 112 have internal threaded holes. The rotating shaft 111 and the push block 112 are threadedly connected. The push block 112 is arranged in the first cavity section and cooperates with the inner wall of the first cavity section. The stop block 113 can The push block 112 and the stop block 113 are movably disposed in the second cavity section. The sides of the push block 112 and the stop block 113 that are in contact with each other have push slopes. The push block 112 is movably provided and pushes against the stop block 113 to pass through. The two pushing slopes push the stopper 113 out of the opening of the second cavity section and abut against the friction layer 132 .

In this embodiment, both the first cavity section and the second cavity section are square holes and their extension directions are perpendicular to each other. After completing the adjustment of the frame body 12 and the drilling part 20, the operator rotates the rotation shaft 111 so that The push block 112 moves downward in the first cavity section. The contact slope of the push block 112 will contact the contact slope of the stop block 113. The stop block 113 will be pushed as the push block 112 moves downward. The stopper 113 moves and one end extends out of the opening of the second cavity section. Continue to rotate the rotating shaft 111 so that the pushing block 112 pushes the end of the stopper 113 to extend out of the opening of the second cavity section and is in close contact with the friction layer 132. Through the rotating shaft, The rotation of 111 realizes the contact and compression of the push block 112 against the stop block 113 and the friction layer 132, ensuring the reliability of friction to prevent rotation. It should be noted that when it is necessary to adjust the frame body 12 and the drilling part 20, it is only necessary to rotate the rotating shaft 111 in the opposite direction, and the pushing block 112 moves upward in the first cavity section under the action of the thread, so that it is opposite to the driving stop block. The driving force for 113 to move in the radial direction becomes smaller, so that the stopper 113 and the friction layer 132 are no longer in close contact or even separated, so that the friction between the stopper 113 and the friction layer 132 is not enough to stop rotation, so that The operator subsequently adjusts the frame body 12 and the drilling part 20 . This arrangement makes the moving directions of the push block 112 and the stop block 113 perpendicular to each other, ensuring the reliability of the separable contact between the stop block 113 and the friction layer 132 and preventing the opening of the placement cavity 142 from being located in the moving direction of the push block 112 , the friction layer 132 needs to be disposed at the bottom of the annular limiting groove 131, causing the rotation of the rotating disk 14 to be blocked.

Preferably, there is a rotation guide structure between the annular limiting protrusion 141 and the annular limiting groove 131 to prevent the annular limiting protrusion 141 from moving in the annular limiting groove 131 and ensure that the relative movement of the two is restricted, wherein , the rotation guide structure can also be an annular protrusion and an annular groove, the annular protrusion and the annular groove are limited to cooperate and avoid the annular limit groove 131 and the side wall of the annular limit protrusion 141 on the side where the friction layer 132 is located.

Optionally, the locking assembly 11 also includes a reset assembly, which is used to reset the stop block 113 when the pushing block 112 moves upward. The reset component can be an elastic component such as a spring.

The support positions and the corresponding transfer positions are at The relative position adjustment in the vertical direction means that the relative position of the interconnected support base 133 and the fixed frame 122 is adjustable in the vertical direction. Specifically, there are four fixing brackets 122 in this embodiment, and correspondingly there are four supporting bases 133. The adjustment components (including There are also four rotating disks 14, adjusting screw rods 15, etc., and at least one locking assembly 11 is installed on any rotating disk 14 and the corresponding support base 133.

The drill head 22 includes a moving plate 222 and a driving member 223 connected to each other. The driving member 223 is drivingly connected to the drill bit 221. The driving part 21 is drivingly connected to the moving plate 222. The moving plate 222 is connected to a plurality of protective plates 31 in the circumferential direction.

In this embodiment, when drilling is not performed, the protective part and the drill bit 221 are spaced apart from the ground in the height direction. After drilling, the driving part 21 drives the drill head 22 and the protective part to move downward together, and the drill bit 221 first contacts the ground. The drill head 22 and the protective part are connected and rotated under the driving action of the driving member 223 to perform preliminary drilling on the ground. When the drill head 22 and the protective part continue to move downward, the protective part contacts the ground, and the lower opening of the drilling protection area of the protective part is blocked. The ground is blocked to stop splashes during drilling and ensure the safety of drilling.
