Technical Field

[0001] The present application belongs to the technical field of coal mine drilling rigs, and specifically relates to a supporting device for a coal mine drilling rig. Background Art

[0002] A drilling rig is a mechanical device that drives the drill to drill underground to obtain physical geological data during the exploration or development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.). Its main function is to drive the drill to break the rock at the bottom of the hole and lower or lift the drill in the hole. When using a coal mine drill for operation, it is necessary to support the coal mine drill to ensure the normal operation of the coal mine drill when drilling.

[0003] For example, patent number CN 214463936 U discloses a coal mine drilling rig support device.

[0004] In the process of using this device, it was found that the technology has the following problems: the universal wheels are set at the bottom of the device, which facilitates the movement of the device. However, when the device is started to drill holes, due to the lack of effective support design at the bottom and the back of the force-bearing surface, it may cause insufficient drilling contact force and cause the device to tilt, which in turn has an adverse effect on drilling. In order to solve this problem, it is necessary to optimize the design of the product and propose a coal mine drilling rig support device. Utility Model Content

A gear 18 meshing with the rack 14 is rotatably installed between the outer ends of the two fixing frames 17. The gear 18 is a half-circle structural design, and the outer peripheral gear arc length of the gear 18 is adapted to the length of the rack 14. A No. 1 hydraulic rod 19 is fixedly installed on the outer end of the gear 18 on the right side of the lifter 9, and a No. 3 motor 20 is fixedly installed on the outer end of the No. 1 hydraulic rod 19, and a No. 3 motor 20 is fixedly installed on the output shaft of the No. 3 motor 20, and a drill rod is provided on the output shaft of the No. 3 motor 20, and a back plate 21 is fixedly installed on the outer end of the gear 18 on the left side of the lifter 9, and a pair of No. 2 hydraulic rods 22 are fixedly installed on the outer end of the back plate 21, and a butt plate 23 is fixedly installed on the extended end of the No. 2 hydraulic rod 22.

[0025] The implementation principle of the embodiment of the present application is:

[0026] First, by setting the anchor plate 7, when it is necessary to move the device to the drilling position, start the No. 1 motor 6 to drive the screw rod 5 to rotate, and then drive the adjusting plate 4 to move upward and plug into the mover 2. At this time, the anchor plate 7 moves upward with the adjusting plate 4, so that the roller 3 installed on the outside of the mover 2 can contact the ground, and the device can be pushed to the position where the drilling is required.

At this time, the roller 3 is lifted away from the ground, and then an anchor rod or soil nail is used to pass through the anchor hole 8 on the anchor plate 7 from top to bottom, so that the bottom end of the anchor rod or soil nail is inserted into the foundation, so that the device is firmly fixed on the base surface, preparing for subsequent drilling.

[0027] Furthermore, by setting relevant components on both sides of the lifting block 10, when the device is fixed on the base surface, first start the No. 2 motor 12 to drive the threaded rod 11 to rotate, and then drive the lifting block 10 to move up and down to control the drilling height of the drill rod on the No. 3 motor 20. After the height is determined, start the electric push rod 16 to extend or contract, and then drive the rack 14 to move up and down. At this time, the gear 18 will be engaged by the rack 14 and rotate at a certain angle. Based on this function, the rotation angle of the gear 18 on the right side can be used to adjust the drilling angle, and the rotation angle of the gear 18 on the left side can be used to adjust the support angle. After the support angle is adjusted, start the No. 2 hydraulic rod 22 to extend, so that the abutment plate 23 can abut against the surrounding walls or foundations, thereby exerting a supporting force during drilling to ensure stability during drilling.
