Description

Technical Field

[0001] The utility model relates to the technical field of monorail cranes, in particular to a synchronous retracting and extending device for an air source pipe of a monorail crane. Background Art

[0002] Monorail crane is suitable for transporting materials, anchor rods, etc. from the coal mine material yard to the head, and is also suitable for short-distance transportation in the tunnel. It mainly uses the gas source in the tunnel for transportation, which is environmentally friendly and pollution-free. The maximum traction force of this product is 10kN, the maximum horizontal load is 10T, and the maximum working angle is 20°. It can well meet the normal work of the excavation working face and related working conditions. The power of the pneumatic monorail crane comes from a high-pressure gas source. Generally, there are multiple gas sources along the tunnel under the mine. The pneumatic monorail crane is connected to the gas source through an air pipe. When the pneumatic monorail crane moves along the monorail, the air pipe connecting the gas source and the monorail crane will extend or shorten, so a retraction device is required to retract it.

[0003] Since the thickness of gas source pipes varies, and gas source pipes of different diameters require retraction and extension devices of different diameters, if a gas source pipe that is too thick is used with a retraction and extension device that is too thin, the gas source pipe will break. The current equipment has a fixed size, which makes the equipment unable to be used for gas source pipes of different diameters, thereby reducing the scope of use of the equipment. In addition, since the gas source pipe will be contaminated with various impurities during use, the impurities will damage the gas source pipe, and the current equipment cannot clean it, thereby shortening the service life of the equipment. Therefore, a monorail hanging gas source pipe synchronous retraction and extension device is urgently needed to improve the above problems. Utility Model Content

[0042] The implementation principle of this embodiment is:

[0043] The monorail hanging gas source pipe synchronous retraction and extension device is provided with an adjustment mechanism 11. When using the device, the staff first rotates the handle 20. The rotation of the handle 20 can drive the threaded rod 13 to rotate. Since the rotating shaft 7 does not rotate, the connecting rod 15 can be limited to prevent the connecting rod 15 from rotating, so that the threaded sleeve 14 can move on the outer surface of the threaded rod 13. The movement of the threaded sleeve 14 can drive one end of the connecting rod 15 to move, so that the moving rod can be rotated. Since the connecting rod 15 is rotatably connected to the slider 16, the other end of the moving rod can be moved up and down. Since the slider 16 can move inside the slide groove 10, it can The slider 16 moves up and down, and the up and down movement of the slider 16 can drive the movable plate 17 to move, so that the diameter of the equipment can be adjusted, so that the equipment can be suitable for gas source pipes of different sizes, so as to expand the use range of the equipment. When the diameter of the equipment is adjusted to the required diameter, the staff rotates the positioning pin 19, and the rotation of the positioning pin 19 can make the positioning pin 19 contact with the positioning hole 21, so as to position the rotating plate 18, so as to prevent the rotating plate 18 from rotating, so as to prevent the threaded rod 13 from rotating, so as to position the threaded sleeve 14, so as to position the position of the movable plate 17, so as to fix the diameter of the equipment.

[0044] The staff then pushes the movable plate 29. Since a sliding block 33 is provided at the bottom of the movable plate 29, the sliding block 33 can move inside the sliding groove 32, thereby enabling the movable plate 29 to move. The movement of the movable plate 29 can drive the installation frame 30 to move, and the movement of the installation frame 30 can drive the sponge pad 31 to move. Subsequently, the staff passes the air source pipe through the sponge pad 31. At this time, the sponge pad 31 contacts the outer surface of the air source pipe, and since the sponge pad 31 is a flexible material, it can be deformed, thereby being able to be used for air source pipes of different diameters, and the installation frame 30 can limit the air source pipe to prevent the air source pipe from falling off. Subsequently, the staff fixes the air source pipe to the outer surface of the movable plate 17 and rotates the limiting rod 34. The limiting rod 34 will contact the limiting hole 35, thereby being able to fix the movable plate 29, thereby being able to fix the installation frame 30, thereby being able to limit the air source pipe. Finally, the staff installs the equipment in the desired position through the lifting ear 2.

[0045] When the air source pipe needs to be retracted or extended, the staff starts the pneumatic motor 5. The pneumatic motor 5 starts working and can drive the driving wheel 39 to rotate. Since the driving wheel 39 is connected to the driven wheel 38, the driving wheel 39 can drive the driven wheel 38 to rotate. The rotation of the driven wheel 38 can drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 can drive the movable plate 17 to rotate, so that the air source pipe can be retracted or extended. At the same time, the staff starts the cylinder 26. The cylinder 26 can push the telescopic rod 27 to retract. Since the auxiliary rod 36 can start the limiting effect on the sliding frame 28 , which can make the sliding frame 28 move left and right, which can make the mounting frame 30 move left and right, which can drive the gas source pipe to move left and right, which can guide the gas source pipe when it is collected, thereby preventing the gas source pipe from being collected unevenly, which can facilitate the use of the gas source pipe next time, thereby improving work efficiency, and in the process of collecting the gas source pipe, since the outer surface of the gas source pipe is in contact with the sponge pad 31, the sponge pad 31 can clean the outer surface of the gas source pipe, thereby preventing impurities from damaging the gas source pipe, thereby extending the service life of the equipment.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. The monorail hanging gas source pipe synchronous retraction and extension device is provided with an adjustment mechanism 11. By rotating the handle 20, the threaded rod 13 can be rotated, thereby moving the threaded sleeve 14, and then moving the movable plate 17, thereby adjusting the size of the device, thereby making the device suitable for gas source pipes of different sizes. By rotating the positioning pin 19, the rotating plate 18 can be fixed, thereby fixing the threaded rod 13, thereby expanding the range of use of the device.

[0048] 2. The monorail hanging gas source pipe synchronous retracting and extending device is provided with a cleaning mechanism 12. By moving the sliding frame 28, gas source pipes of different sizes can pass through the sponge pad 31. The sponge pad 31 can clean the gas source pipe and prevent impurities from damaging the gas source pipe, thereby extending the service life of the equipment.

[0049] 3. The monorail hanging air source pipe synchronous retraction and extension device is provided with a cleaning mechanism 12, which can drive the telescopic rod 27 to extend and retract through the cylinder 26, and then drive the sliding frame 28 to move, and then drive the air source pipe to move, and then guide the air source pipe, and then facilitate the subsequent use of the air source pipe, and then improve work efficiency.
