Description

Technical Field

[0001] This utility model relates to a mining outrigger type nut installer, belonging to the field of nut installation technology. Background Technology

[0002] Rock bolts are a fundamental component of roadway support in modern coal mines, reinforcing the surrounding rock and allowing it to support itself. Rock bolts typically have a long threaded section at one end, into which a nut is screwed to adjust the preload. After roadway excavation and the installation of rock bolts or anchor mesh, changes in ground pressure or surrounding rock may cause insufficient anchoring strength, requiring further tightening of the anchor nuts. As the coal face advances, the rock bolts or anchor mesh support in the roadway are dismantled, necessitating the removal of the anchor nuts. However, current nut installers are inconvenient to operate. Installing and removing nuts at the roadway roof rock bolts requires workers to climb high and low, which is time-consuming, labor-intensive, inefficient, and poses safety hazards due to working at heights. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a mining outrigger type nut installer that is easy to operate, improves work efficiency, and is suitable for installing and disassembling anchor bolt nuts in roadways of different heights.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a mining outrigger type nut installer, including a buffer mounting frame, on which a vertically arranged hydraulic drive device is provided, and a nut installation head is provided above the buffer mounting frame, the nut installation head being fixed to the output end of the hydraulic drive device; a vertically arranged telescopic outrigger is provided at the bottom of the buffer mounting frame, the telescopic outrigger driving the buffer mounting frame to move up and down, driving the hydraulic drive device and the nut installation head to move up and down synchronously; an operating arm is hinged to the side of the buffer mounting frame, one end of the operating arm is provided with a valve block, a hydraulic pump station is connected to the valve block through an oil outlet pipe, and the valve block is connected to two working oil ports of a hydraulic motor through an oil inlet pipe; a handle is symmetrically provided at the other end of the operating arm, and a trigger is provided on one side of the handle, the trigger controlling the movement of the valve core of the valve block, thereby controlling the forward and reverse rotation of the hydraulic motor, driving the nut installation head to install or remove the nut.

[0005] The hydraulic drive device is a hydraulic motor.

[0006] The telescopic outriggers are equipped with a top point at the bottom.

[0007] The telescopic outrigger is a hydraulic cylinder.

[0008] Compared with existing technologies, the advantages of this utility model are as follows: A mining outrigger-type nut installer uses hydraulic oil as the working medium. A trigger controls the valve block, which in turn drives the hydraulic motor to rotate forward and backward, and the speed can be adjusted, thus realizing the installation and removal of anchor bolt nuts. The hydraulic cylinder acts as an outrigger, providing not only support but also adjustable thrust and speed, thus adapting to a wide range of applications. It can achieve high-speed, high-quality installation and removal of anchor bolt nuts in roadways of various heights (1.8m ≤ H ≤ 4.5m), avoiding the safety hazards of working at heights. It is unaffected by the environment in fully mechanized tunnels and can operate within a small area. This application is easy to operate, small in size, and highly efficient, easily handling the installation and removal of top nuts. Attached Figure Description

Detailed Implementation

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1 , 2As shown in Figure 3, a mining outrigger-type nut installer in this embodiment includes a buffer mounting frame 5. A vertically arranged hydraulic motor 4 is mounted on the buffer mounting frame 5, and a nut mounting head 6 is located above the buffer mounting frame 5, fixed to the output end of the hydraulic motor 4. A vertically arranged hydraulic cylinder 1 is located at the bottom of the buffer mounting frame 5, with a tip 9 at the bottom of the cylinder body. The tip 9 is inserted into the roadway ground, supporting the cylinder on the ground. When the hydraulic cylinder 1 drives the buffer mounting frame 5 to move up and down, it drives the hydraulic motor 4 and the nut mounting head 6 to rise synchronously, bringing the nut mounting head 6 closer to the top anchor rod, or drives the hydraulic motor 4 and the nut mounting head 6 to fall synchronously, thereby reducing the size of the equipment. An operating arm 7 is hinged to the side of the buffer mounting frame 5, and the operating arm 7 can swing around the hinge, facilitating operation in confined spaces. One end of the control arm 7 is equipped with a valve block 3. The hydraulic pump station is connected to the pressure port of the valve block 3 through an oil outlet pipe. The valve block's actuator port is connected to the two working ports of the hydraulic motor 4 through an oil inlet pipe. The valve block 3's return port is connected to the hydraulic pump station's oil tank 10. The other end of the control arm 7 is symmetrically equipped with handles 2. One handle side is equipped with a trigger 8, which is connected to the valve core of the valve block 3. Pushing the trigger 8 controls the movement of the valve core of the valve block, thereby controlling the forward and reverse rotation of the hydraulic motor 4, which drives the nut mounting head 6 to install or remove the nut. The degree to which the trigger is opened adjusts the speed of the hydraulic motor 4, thereby adjusting the installation and removal speed of the nut mounting head.

[0012] The aforementioned hydraulic pump station includes a motor 11, which is connected to the hydraulic pump via a coupling. The motor drives the hydraulic pump to operate, and the hydraulic pump pumps the oil in the oil tank into the valve block.

[0013] Using hydraulic oil as the working medium, a trigger controls the valve block, which in turn drives the hydraulic motor to rotate forward and backward, and the speed can be adjusted, enabling the installation and removal of anchor bolt nuts. The hydraulic cylinder acts as an outrigger, providing not only support but also adjustable thrust and speed, thus adapting to a wide range of applications. It can achieve high-speed, high-quality installation and removal of anchor bolt nuts in roadways with heights ranging from 1.8m to 4.5m, avoiding the safety hazards of working at heights. It is unaffected by environmental conditions within fully mechanized tunnels and can operate within a small area. This application is easy to operate, compact, and highly efficient, easily handling the installation and removal of top nuts.

[0014] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
