Technical Field

[0001] The utility model relates to the technical field of anchor drilling machines, and in particular to an anchor drilling machine that is convenient for stable docking. Background Art

[0002] Anchor drills, also known as anchor drills in some contexts, are drilling tools used in coal mine roadway anchor support. They offer significant advantages in improving support effectiveness, reducing support costs, accelerating roadway construction, reducing auxiliary transportation, alleviating labor intensity, and increasing roadway cross-sectional utilization. Anchor drills are key equipment in anchor support, impacting the quality of anchor support, including the accuracy of the anchor hole's orientation, depth, and diameter, as well as the quality of anchor installation. They also impact operator safety, labor intensity, and operating conditions.

[0003] However, traditional anchor drilling rigs may cause the drill to shake up and down due to the hardness of the rock during operation, making the anchor drilling rig unstable, resulting in deviations in the drilling position and direction, and making the drilling operation less effective. In order to ensure the stability of the anchor drilling rig, an anchor drilling rig that facilitates stable docking is proposed. Utility Model Content

[0008] Preferably, the damper includes a main fixed block, which is fixed to the top of the support plate, and the outside of the main fixed block is rotatably connected to the main connecting piece through a fixed rod, the top of the main connecting piece is fixedly connected to the cylinder body, the inside of the cylinder body is fixedly connected to a spring, the top of the spring is fixedly connected to a piston, the piston is slidably connected to the inside of the cylinder body, the inside of the piston is fixedly connected to a sliding rod, the top of the sliding rod extends to the top of the cylinder body and is fixedly connected to a secondary connecting piece, the outside of the secondary connecting piece is rotatably connected to the secondary fixed block through a fixed rod, and the top of the secondary fixed block is fixedly connected to the bottom of the sliding plate.

[0009] Preferably, the fixing assembly includes a cylinder, which is fixed on the top of the base plate, and a secondary through hole is opened on the outside of the base plate. The output end of the cylinder extends to the inside of the secondary through hole and is fixedly connected to a fixing plate, and the bottom of the fixing plate is fixedly connected to a fixing tooth.

[0013] The working principle and beneficial effects of the utility model are as follows:

[0014] 1. In the present invention, the screw often produces impact during operation. The impact drives the spindle motor to impact the threaded protective sleeve through the screw. The impact on the threaded protective sleeve drives the main fixed block through the support assembly. The main fixed block drives the cylinder to move through the fixed rod and the main connecting piece. Due to the combined effect of the deformation of the damping medium and the spring inside the cylinder, the piston moves less, which cushions the impact to a certain extent. As a result, the impact on the handheld handle on the sliding plate after the impact passes through the damper is reduced, thereby reducing the impact on the worker's arms and body, making the drill less likely to become unstable during operation and allowing the worker to hold it more stably.

[0015] 2. In the present invention, when the device is moved to a suitable position through the universal wheel, the cylinder is started to drive the fixed plate to place the fixed teeth on the ground. After the position is fixed, the spindle motor is started to drive the screw to drill a hole below. The screw moves inside the sliding plate under the cooperation of the limit block and the column groove. The sliding plate slides inside the fixed frame under the limitation of the guide rod to prevent the drilling rig from tilting during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, in this embodiment, it includes a base plate 1, a fixing frame 2 is fixedly connected to the top of the base plate 1, a sliding component is installed inside the fixing frame 2, a spindle motor 6 is connected to the top of the base plate 1 through the sliding component, a threaded protective sleeve 7 is fixedly connected to the bottom of the spindle motor 6, a screw 8 is fixedly installed at the output end of the spindle motor 6, a support component is installed on the outside of the threaded protective sleeve 7, a damper 13 is installed on the top of the support component, and a fixed component is installed on the top of the base plate 1.

[0026] Furthermore, the sliding assembly includes a guide rod 5, which is fixed inside the fixed frame 2. The outside of the guide rod 5 is slidably connected to a sliding plate 3, the top of the sliding plate 3 contacts the bottom of the spindle motor 6, and the sliding plate 3 slides inside the fixed frame 2 under the limitation of the guide rod 5.

[0027] Furthermore, the support assembly includes a kit 11, which is connected to the outside of the threaded protective sleeve 7 through threads, and a support plate 12 is connected to the top of the kit 11 through screws, so that the kit 11 is easy to disassemble and replace.

[0028] The top of the spring 134 is fixedly connected to the piston 136, and the piston 136 is slidably connected to the inside of the cylinder 133. The piston 136 is fixedly connected to the inside of the cylinder 133. The top of the spring 134 is fixedly connected to the piston 136. The piston 136 is slidably connected to the inside of the cylinder 133. The piston 136 is fixedly connected to the inside of the cylinder 133. The top of the sliding rod 135 extends to the top of the cylinder 133 and is fixedly connected to the secondary connecting piece 137. The outside of the secondary connecting piece 137 is rotatably connected to the secondary fixing block 138 by the fixing rod. The top of the secondary fixing block 138 is fixedly connected to the bottom of the sliding plate 3. The main fixing block 131 drives the cylinder 133 to move through the fixing rod and the main connecting piece 132. Due to the combined action of the deformation of the damping medium in the cylinder 133 and the spring 134, the piston 136 moves less, which provides a certain buffer for the impact.

[0029] Furthermore, the outside of the threaded protective sleeve 7 is fixedly connected to the limiting block 9, and a columnar groove 10 is opened inside the sliding plate 3. The outside of the limiting block 9 cooperates with the inside of the columnar groove 10, and the spindle motor 6 moves inside the sliding plate 3 through the threaded protective sleeve 7 under the cooperation and limitation of the limiting block 9 and the columnar groove 10.

[0030] Furthermore, a main through hole 14 is opened on the outside of the bottom plate 1 , and the screw rod 8 is located inside the main through hole 14 , so that the screw rod 8 can smoothly pass through the bottom plate 1 to perform drilling work.

[0031] Example 2

[0032] like Figures 1 to 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a fixing component includes a cylinder 15, the cylinder 15 is fixed on the top of the base plate 1, and a secondary through hole 18 is opened on the outside of the base plate 1. The output end of the cylinder 15 extends to the inside of the secondary through hole 18 and is fixedly connected to a fixing plate 16, and a fixing tooth 17 is fixedly connected to the bottom of the fixing plate 16. Starting the cylinder 15 drives the fixing plate 16 to place the fixing tooth 17 on the ground, thereby fixing the position of the device.

[0033] Furthermore, a hand-held handle 4 is fixedly connected to the outside of the sliding plate 3, and a plurality of universal wheels 19 are fixedly installed on the bottom of the base plate 1. When the device moves via the universal wheels 19, the cost of manual movement is reduced.

[0034] In this embodiment, after the device is moved to a suitable position through the universal wheel 19, the cylinder 15 is started to drive the fixed plate 16 to place the fixed tooth 17 on the ground. After the position is fixed, the spindle motor 6 is started to drive the screw 8 to drill a hole below. The screw 8 moves inside the sliding plate 3 under the cooperation and limitation of the limit block 9 and the columnar groove 10. The sliding plate 3 slides inside the fixed frame 2 under the limitation of the guide rod 5. The screw 8 often produces impact during operation. The impact drives the spindle motor 6 to impact the threaded protective sleeve 7 through the screw 8. The impact on the threaded protective sleeve 7 drives the main fixed block 131 through the support assembly. The main fixed block 131 drives the cylinder body 133 to move through the fixed rod and the main connecting member 132. Due to the combined action of the damping medium inside the cylinder body 133 and the deformation of the spring 134, the piston 136 moves less, which provides a certain buffer for the impact, so that the impact on the handheld handle 4 on the sliding plate 3 after the impact passes through the damper 13 is reduced, thereby reducing the impact on the worker's arm and body.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
