Description

Technical Field

[0001] This utility model relates to the field of torque shaft replacement technology, and in particular to a hand-cranked torque shaft replacement device. Background Technology

[0002] In the transmission system of a continuous mining machine, the torque shaft is a core safety protection and power transmission component. It serves as a power bridge between the cutting section and the main transmission system, transmitting the torque output by the motor to the working mechanism stably and efficiently. This directly affects the safety, stability, and service life of the equipment.

[0003] The torque shaft of the continuous mining machine often breaks. After it breaks, the torque shaft becomes embedded inside the reducer and is difficult to remove. It requires tools to forcibly pull out the broken torque shaft, which makes it take a long time to replace the torque shaft and is also more likely to damage the reducer. It is time-consuming, labor-intensive and affects work efficiency.

[0004] Therefore, in view of the inconvenience of removing the torque shaft after it breaks in the existing continuous mining machine, a hand-cranked torque shaft replacement device can be designed. By using a hand-cranked rotation and pulling method, the difficulty of removing the broken torque shaft can be reduced, the operation time for removing and transporting the torque shaft can be saved, and the device is simple in structure and has low operating cost, which greatly improves the efficiency of maintenance work. Utility Model Content

[0005] To overcome the problem that most continuous mining machines have difficulty removing the torque shaft after it breaks, requiring tools to forcibly pull out the broken torque shaft, which leads to a long time to replace the torque shaft, is more likely to damage the reducer, is time-consuming and labor-intensive, and affects work efficiency, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a hand-cranked torque shaft replacement device, including a horizontal steel bar, an adjusting screw, a crossbar, a handle, a connecting component, and a mating screw. The adjusting screw passes through the middle of the horizontal steel bar and is threadedly connected to the horizontal steel bar. A crossbar is provided at the rear end of the adjusting screw bar, a handle is provided at one end of the crossbar, and a mating screw is provided at the front end of the adjusting screw bar. The mating screw is fixedly connected to the adjusting screw bar through the connecting component.

[0007] Preferably, by setting a horizontal steel threaded rotating connection to the adjusting screw, the handle is grasped and the horizontal bar is rotated, thereby driving the adjusting screw to rotate in and out along the horizontal steel. The connecting component fixes the mating screw to the front end of the adjusting screw. The mating screw is inserted into the threaded position of the torque shaft. Rotating the adjusting screw drives the mating screw to pull out the torque shaft. This reduces the difficulty of removing the broken torque shaft, saves the operation time of removing and transporting the torque shaft, saves time and effort, and has a simple structure and low operating cost, thereby improving the efficiency of maintenance work.

[0008] Preferably, the connecting assembly includes a connecting post and a U-shaped channel steel. The front end of the adjusting screw is provided with a connecting post, and the two ends of the connecting post are connected to the U-shaped channel steel. The mating screw is provided at the front end of the U-shaped channel steel.

[0009] Preferably, both ends of the connecting column are fixedly connected to the U-shaped channel steel.

[0010] Preferably, the connecting screw is fixed to the front end of the U-shaped channel steel.

[0011] Preferably, the connecting assembly also includes threaded holes, mounting bolts, and lock nuts. The connecting column is a hollow column, and the side plate of the U-shaped channel steel has two sets of threaded holes symmetrically opened. The threaded holes are connected to the threaded grooves of the connecting column. The mounting bolt passes through the threaded holes and the connecting column and the U-shaped channel steel. The mounting bolt is rotatably connected to the threaded grooves and threaded holes of the connecting column. The other end of the mounting bolt is rotatably connected to a lock nut.

[0012] Preferably, the connecting assembly further includes a through hole, a connecting plate, a first positioning post, a first positioning groove, a second positioning post, and a second positioning groove. The front end of the U-shaped channel steel has a through hole with a diameter larger than any size of mating screw. The top of the mating screw is provided with a connecting plate. The bottom end of the connecting plate has two sets of first positioning posts symmetrically arranged. The inner side of the U-shaped channel steel has two sets of first positioning grooves symmetrically arranged. The first positioning posts are fitted into the first positioning grooves. The outer side of the connecting post has two sets of second positioning posts symmetrically arranged. The top end of the connecting plate has two sets of second positioning grooves symmetrically arranged. The second positioning posts are fitted into the second positioning grooves.

[0013] The beneficial effects of this utility model are: When removing the torque shaft, insert the mating screw at the front end of the adjusting screw into the threaded position of the torque shaft, grasp the handle and rotate the crossbar, thereby driving the adjusting screw to rotate along the crossbar. Rotating the adjusting screw causes the mating screw to be pulled out of the torque shaft, thus reducing the difficulty of removing the broken torque shaft and saving the operation time of removing and transporting the torque shaft. This solves the problem that most continuous mining machines have torque shafts that are difficult to remove after breakage, requiring tools to forcibly pull out the broken torque shaft, resulting in long replacement times for the torque shaft, and making it easier to damage the reducer. This is time-consuming, labor-intensive, and affects work efficiency, thus improving the efficiency of maintenance work. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1 Please see Figure 1 This utility model provides an embodiment: a hand-cranked torque shaft replacement device, including a horizontal steel bar 1, an adjusting screw 2, a crossbar 3, a handle 4, a connecting assembly, and a mating screw 5. The adjusting screw 2 passes through the middle of the horizontal steel bar 1 and is threadedly connected to the horizontal steel bar 1. The crossbar 3 is provided at the rear end of the adjusting screw 2, and the handle 4 is provided at one end of the crossbar 3. The mating screw 5 is provided at the front end of the adjusting screw 2 and is fixedly connected to the adjusting screw 2 through the connecting assembly.

[0017] Please see Figure 2 In this embodiment, the connecting assembly includes a connecting post 501 and a U-shaped channel steel 502. The front end of the adjusting screw 2 is provided with the connecting post 501, and the two ends of the connecting post 501 are connected to the U-shaped channel steel 502. The mating screw 5 is provided at the front end of the U-shaped channel steel 502. The two ends of the connecting post 501 are fixedly connected to the U-shaped channel steel 502, and the mating screw 5 is fixed at the front end of the U-shaped channel steel 502. The U-shaped channel steel 502 is fixed to one end of the adjusting screw 2 by the connecting post 501, and the mating screw 5 is fixed by the U-shaped channel steel 502.

[0018] When removing the torque shaft, insert the mating screw 5 at the front end of the U-shaped channel steel 502 into the threaded position of the torque shaft, grasp the handle 4 and rotate the crossbar 3. Rotating the crossbar 3 will drive the adjusting screw 2 to rotate along the crossbar 1. Unscrew the adjusting screw 2 to pull out the mating screw 5 and remove the torque shaft.

[0019] Example 2 Please see Figure 2 and Figure 3 The difference from Embodiment 1 is that in this embodiment, the connecting assembly further includes a threaded hole 601, a mounting bolt 602, and a locking nut 603. The connecting column 501 is a hollow column, and the side plate of the U-shaped channel steel 502 has two sets of threaded holes 601 symmetrically opened. The threaded holes 601 are connected to the threaded grooves of the connecting column 501. The mounting bolt 602 passes through the threaded holes 601, penetrating the connecting column 501 and the U-shaped channel steel 502. The mounting bolt 602 is rotatably connected to the threaded grooves and threaded holes 601 of the connecting column 501. The other end of the mounting bolt 602 is rotatably connected to the locking nut 603. In this example, the front end of the adjusting screw 2 can be detachably and replaceably fixed with U-shaped channel steel 502 with mating screws 5 of different sizes. During installation, align the threaded hole 601 of the U-shaped channel steel 502 with the threaded groove of the connecting column 501, and then screw the mounting bolt 602 into the U-shaped channel steel 502 and the connecting column 501, so that the mounting bolt 602 passes through the U-shaped channel steel 502 and the connecting column 501. Finally, screw the locking nut 603 into the other end of the mounting bolt 602 to lock the position of the mounting bolt 602, thereby achieving the effect of convenient disassembly and assembly of the U-shaped channel steel 502. The mating screws 5 of the corresponding size can be replaced according to the different sizes of torque shaft threads.

[0020] Example 3 Please see Figure 4 , Figure 5 and Figure 6The difference from Embodiment 2 is that, in this embodiment, the connecting assembly further includes a through hole 701, a connecting plate 702, a first positioning post 703, a first positioning groove 704, a second positioning post 705, and a second positioning groove 706. A through hole 701 is provided at the front end of the U-shaped channel steel 502. The diameter of the through hole 701 is larger than that of any size mating screw 5. A connecting plate 702 is provided at the top of the mating screw 5. Two sets of first positioning posts 703 are symmetrically arranged at the bottom end of the connecting plate 702. Two sets of first positioning grooves 704 are symmetrically arranged on the inner side of the U-shaped channel steel 502, and the first positioning posts 703 are fitted into the first positioning grooves 704. Two sets of second positioning posts 705 are symmetrically arranged on the outer side of the connecting post 501. Two sets of second positioning grooves 706 are symmetrically arranged at the top end of the connecting plate 702, and the second positioning posts 705 are fitted into the second positioning grooves 706. Next, in this embodiment, the mating screw 5 and the U-shaped channel steel 502 are detachably connected, thus eliminating the need for multiple U-shaped channel steels 502. The corresponding mating screw 5 can be directly replaced on the U-shaped channel steel 502 according to the torque shaft thread of different sizes. When installing the mating screw 5, the mating screw 5 is passed through the through hole 701, so that the connecting plate 702 abuts against one side of the U-shaped channel steel 502. At this time, the first positioning post 703 is embedded in the first positioning groove 704, and the installation position of the mating screw 5 is initially determined. Then, the U-shaped channel steel 502 is installed on both ends of the connecting post 501, so that the second positioning post 705 is embedded in the second positioning groove 706, and the mating screw 5 is clamped and fixed on the U-shaped channel steel 502, thereby preventing the mating screw 5 from deflecting when the adjusting screw 2 is unscrewed. Finally, the U-shaped channel steel 502 installation steps of the above embodiment 2 are repeated to complete the replacement operation.

[0021] Through the above steps, by setting the horizontal steel 1 to be threadedly connected to the adjusting screw 2, grasping the handle 4 and rotating the horizontal bar 3, the adjusting screw 2 is driven to screw in and out along the horizontal steel 1. The connecting assembly fixes the connecting screw 5 to the front end of the adjusting screw 2. By using the connecting screw 5 to be embedded in the threaded position of the torque shaft, rotating the adjusting screw 2 drives the connecting screw 5 to pull out the torque shaft, thereby reducing the difficulty of removing the broken torque shaft, saving the operation time of removing and transporting the torque shaft, saving time and effort, and with a simple structure and low operating cost.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
