In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-8, the present invention provides an engineering drilling rig boom, as shown in Figures 1 and 2, including a supporting plate mechanism 1, a hydraulic cylinder 2, a luffing mechanism 3, a hydraulic cylinder 2 4, and a propulsion mechanism Top mounting support 5, sprocket mounting support 6, chain 7, driving sprocket 8, guide column 9, hydraulic cylinder three 10, pressurized cylinder mounting support slider group 11, power head 12, power head mounting support The slide block group 13, the driven sprocket 14, the propulsion mechanism bottom installation support 15, the rotating rod fixed frame 16, the hydraulic motor mounting frame 17, and the hydraulic motor 18 form.

The top of the luffing mechanism 3 (as shown in Figures 5 and 6) is fixedly connected to the base of the hydraulic cylinder 2 4, the end of the piston rod of the hydraulic cylinder 2 4 is hingedly connected to the mounting support on the top of the propulsion mechanism, and the hydraulic cylinder 3 is fixed with 10 bolts On the pressurized cylinder installation support slider group 11, and the lugs of the hydraulic cylinder three 10 are connected with the lugs of the power head installation support slider group 13, the pressurized cylinder installation support slider group 11 is installed on the other two On a guide column 9 and connected with the sprocket chain drive assembly; the power head 12 is installed on the power head installation support slider group 13; the bottom of the propulsion mechanism is connected with a drill pipe fixing frame 16.

The sprocket chain drive assembly includes a hydraulic motor 18, a driving sprocket 8, a driven sprocket 14 and a chain 7. The sprocket mounting support 6 and the hydraulic motor mounting frame 17 are fixedly arranged on the mounting support at the bottom of the propulsion mechanism. The hydraulic motor 18 bolts are fixed on the hydraulic motor mounting frame 17, the output shaft of the hydraulic motor 18 is connected with the driving sprocket 8 through a flat key or a spline, and the chain 7 is transmission connected to the external teeth of the driving sprocket 8 and the driven sprocket 14, The driven sprocket 14 is fixed on the top mounting support of the propulsion mechanism.

The luffing mechanism 3 is an integral welded frame, which is connected with the bracket mechanism 1 and the hydraulic cylinder 1 through the pin shaft. When the drilling rig needs to work, when the hydraulic cylinder 2 is fully extended under the action of high-pressure oil, the hydraulic cylinder 1 passes through The luffing mechanism pushes the entire boom up to rotate 90 degrees around the pin between the bracket mechanism 1 and the luffing mechanism 3, so that the drilling rig boom is in a vertical state as a whole to complete drilling and other work; when the drilling rig does not need to work, the hydraulic cylinder 2. When fully contracted under the action of high-pressure oil, the hydraulic cylinder 1 2 pulls the entire boom upward through the luffing mechanism and rotates 90 degrees in reverse around the pin shaft between the bracket mechanism 1 and the luffing mechanism 3, so that the whole boom of the drilling rig is horizontal state, lowering the center of gravity for easy handling (the vertical and horizontal states can be rigidly positioned by changing the length of the hydraulic cylinder 2 as shown in Figure 7). state, when the hydraulic cylinder 2 4 enters the high-pressure oil to work, the extension or shortening motion can drive the propulsion mechanism to move up or down relative to the luffing mechanism. The hydraulic cylinder 3 10 is fixed on the pressurized cylinder installation support slider group 11 by bolts, and the lugs of the hydraulic cylinder 3 10 are connected with the lugs of the power head installation support slider group 13, as shown in Figure 8.

The pressurized cylinder three 10 enters the high-pressure oil and can apply a working pressure to it when the power head is working.

In the present invention, four guide columns and a slider structure are adopted, the structure is simplified, the symmetrical distribution makes the force uniform, the guide is stable, and the overall weight is reduced. The power head 12 is installed on the slider group 13 of the power head installation support, and the rise, stop and fall of the slider group are controlled by the sprocket mechanism, and the speed and stroke can be directly controlled

When working normally, the traveling mechanism moves the arm frame to the working position, and the hydraulic cylinder one 2 enters the hydraulic oil to do the elongation movement and cooperates with the luffing mechanism 3 to move the entire arm frame guide rail from the horizontal state to the vertical state, and then the hydraulic cylinder one 2 does not move. Then the oil is in the pressure-holding state, and then the hydraulic motor 18 enters the hydraulic oil to drive the driving sprocket 8 to make a rotary motion together, and the chain 7 drives the slider group to slide to the designated position on the guide post 9. After the driving sprocket 8 is locked (equivalent to The chain 7 is also locked, and the pressurized cylinder is installed with the support slider group 11 and is fixed on the designated position of the guide column), the power head 12 enters the hydraulic oil to drive the drill pipe to perform rotary motion together, and the hydraulic cylinder 3 10 enters the hydraulic oil to do the stretching. The long movement pushes the power head down and exerts a vertical downward pressure on the power head, and finally completes the entire drilling movement.
