Utility Model Content

Traditional manual operation requires a lot of time and manpower, while the limit block can be plug-and-play, which greatly improves work efficiency. The push-pull parts provide stable push-pull force through the pneumatic system, which can quickly and stably pull out the pin shaft. The present invention can improve the alignment accuracy and operational efficiency of the support pin shaft by adding laser locators and photoelectric sensors. The laser locator indicates the center position of the pin shaft by emitting a laser beam, assisting the operator in precise alignment. Compared with traditional visual inspection and experience judgment, the laser locator has a high degree of accuracy and stability, which can effectively reduce alignment errors and improve the success rate of disassembly. Laser locators and photoelectric sensors are particularly important in mine environments, which are complex, with insufficient light and narrow space, making manual alignment extremely difficult. Laser locators and photoelectric sensors can provide reliable alignment support in this environment, ensure the accurate disassembly of the pin shaft, and avoid pin shaft damage or support failure caused by inaccurate alignment. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of a hydraulic support pin quick pulling device. DETAILED DESCRIPTION

[0013] like Figure 1As shown, a hydraulic support pin quick pulling device includes a main body 1, a block 2, an air pump, a push-pull member 3, a laser locator 4, a photoelectric sensor 5, and a screw 6. One end of the screw 6 is connected to the push-pull member 3, and the center of the screw 6 is collinear with the center of the block 2; the block 2 is arranged on the main body 1 near the screw end; one end of the air pump is connected to the air source through a pipeline, and the other end is connected to the push-pull member 3. The main body 1 is the basic structure of the entire equipment, made of alloy steel material, and can withstand high pressure and high-intensity working environment. The main body 1 has good wear resistance and corrosion resistance. At the same time, the main body 1 is provided with installation positions and connection points for various functional components to facilitate overall assembly and function realization. One end of the screw 6 is connected to the push-pull member 3; one end of the air pump is connected to the air source through a pipeline, and the other end is connected to the push-pull member 3. The outer side of the main body 1 is sleeved with a bearing, and two connecting rods 8 are symmetrically connected to the bearing. The ends of each connecting rod 8 are respectively connected to a limit block 7, and the two connecting rods 8 are connected to a positioning block 9. The limit block 7 is used to limit the position of the positioning block 9; the positioning block 9 is provided with a threaded hole, and the positioning block 9 is adapted to the screw 6 through the threaded hole. The push-pull member 3 provides a stable push-pull force through the air pump to achieve the rapid insertion and removal of the pin. It is easy to operate, and the push-pull action can be completed by a button or a remote control, which reduces the labor intensity of the operator and improves the disassembly efficiency. First, the connecting rod 8 is clamped on the component where the pin is located to stabilize the main body 1, and then the screw 6 is aligned with the pin. Then the air pump is started to make the screw 6 push and pull the pin to achieve the removal or installation of the pin. After the pin is taken out or installed, the clamping of the connecting rod 8 on the component is released, and finally the operation of installing or removing the pin is completed.

[0014] The stopper 2 has an internal thread, and the screw 6 has an external thread, and the stopper 2 is adapted to the screw 6; when the device is idle, the screw 6 is pushed toward the stopper 2 by an air pump, so that the screw 6 enters the stopper 2, which facilitates the storage and accommodation of the device.

[0015] The photoelectric sensor 5 is connected to the main body 1 through a fixing ring, and the laser locator 4 is connected to the photoelectric sensor 5 through a connecting ring; the centers of the main body 1, the laser locator 4 and the photoelectric sensor 5 are on the same straight line. The laser locator 4 indicates the center position of the pin by emitting a laser beam. The photoelectric sensor 5 is used to detect the position of the pin in real time. Before clamping the pin, the pin is first positioned by the laser locator 4 so that the laser beam is projected onto the center position of the pin. The high-precision detection capability of the photoelectric sensor 5 can ensure that the position of the pin is accurate and avoid disassembly failure or equipment damage due to inaccurate positioning. After the pin is pulled out, the photoelectric sensor 5 can accurately feedback the position of the pin to ensure whether the pin is completely pulled out, thereby ensuring the accuracy and stability of the operation.

[0016] The bearing is sleeved on the outside of the main body 1, and a number of balls are provided inside the bearing, which are used to reduce friction. The bearing is used to support and reduce friction, ensuring the smooth operation of each moving part. The selection of bearings should take into account the load and working environment of the equipment, and high-strength, high-wear-resistant bearing materials are usually selected. The bearing ensures that it can provide stable support and smooth rotation, extending the service life of the equipment. After the screw 6 pulls out the pin, the pin will be clamped by the screw 6 and the block 2. The bearing will rotate under the action of the block 2 as a buffer, extending the service life of the block 2 and the main body 1.

[0017] Workflow

[0018] First, an air pump is used to move the lead screw 6 away from the stopper 2, and then the connecting rod 8 is withdrawn from the bearing. A laser locator is then used to determine the center position of the pin. Once the pin's center position is determined, the connecting rods 8 are passed through the fixed component, positioning them on either side of the component. The connecting rods 8 clamp onto the fixed component, securing the main body 1 and positioning the component between the stopper 2 and the positioning block 9. The positioning block 9 ensures that the centerline of the lead screw 6 is collinear with the centerline of the stopper 2, effectively collinear with the centerline of the lead screw 6. A stopper 7 prevents the positioning block 9 from falling off the connecting rod 8, which would make it impossible to control the movement of the lead screw 6. Finally, the air pump pushes the push-pull member 3, ejecting the pin from the fixed component. The lead screw 6 and the stopper 2 clamp the pin to prevent it from falling off and causing damage. After the photoelectric sensor 5 detects the pin's position, the lead screw 6 is controlled to move away from the stopper 2, removing the pin. After the pin is removed, the screw 6 is moved toward the block 2 by the air pump, and the main body 1 is controlled to prevent the main body 1 from rotating, so that the screw 6 can be inserted into the block 2, reducing the space occupied by the device and facilitating carrying and storage.

[0019] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
