DETAILED DESCRIPTION

[0020] The utility model is further described below in combination with the drawings.

[0021] The directions referred to in the specification are based on the normal working position of the utility model, and do not limit the storage and transportation positions, only represent relative positional relationships, and do not represent absolute positional relationships.

[0022] As Figure 1 shown, a kind of point drive machine, including controller 1, lifting device 2, clamping device 3 and traction device 4 installed on lifting device 2. Controller 1 includes control box 11, control panel is fixedly installed in control box 11, the operation of lifting device 2 and traction device 4 is controlled by control panel.

[0023] Lifting device 2 includes bottom plate 21, lifting platform 22 installed on bottom plate 21 and lifting driving device 23 for driving lifting platform 22 to lift.

[0024] The bottom of the bottom plate 21 is provided with a forklift avoiding groove 210 for the forklift to enter, so that the device can be moved by the forklift. A plurality of guide cylinders 211 are uniformly arranged on the bottom plate 21, and a guide shaft 212 is slidingly installed in the guide cylinder 211. The top of the guide shaft 212 is fixedly installed on the lifting platform 22. The lifting drive device 23 can be a gas cylinder, an electric cylinder or an electric push rod. In order to realize precise lifting control, the lifting drive device 23 adopts a worm gear lifting machine in the embodiment. The worm gear lifting machine is controlled by a stepping motor 231. The worm gear 232 is fixed at the middle position of the lifting platform 22, and the guide cylinders 211 are uniformly arranged around the worm gear 232, so as to realize stable support. The lifting drive device 23 is signal connected to the controller 1. In the embodiment, the control box 11 is provided with an up or down button. Each time the button is pressed, the stepping motor 231 runs a preset number of steps, so as to realize the inching lifting of the lifting platform 22, and the accurate control of the height. In actual application, a handheld remote controller can also be used to control the lifting drive device 23.

[0025] The clamping device 3 includes two groups of sliding frames 31 slidingly installed on the lifting platform 22 and a clamping drive device 32 driving the two groups of sliding frames 31 to slide relative to or away from each other.

[0026] A plurality of guide rods 33 are fixedly installed on the lifting platform 22. In the embodiment, two guide rods 33 are arranged. The sliding frames 31 are slidingly installed on the two guide rods 33. The clamping drive device 32 includes a lead screw 321 rotatingly installed on the lifting platform 22, which is arranged in parallel with the guide rods 33. At least one lead screw nut is installed on the lead screw 321, and the lead screw nut is fixedly installed on any sliding frame 31. By rotating the lead screw 321, any sliding frame 31 is driven to approach or move away from the other sliding frame 31, so as to realize the relative or away movement of the two sliding frames 31. Of course, two sections of lead screw threads can also be arranged on the lead screw 321, and the rotation directions of the two sections of lead screw threads are opposite. One lead screw nut is installed on each section of lead screw thread, and the two lead screw nuts are fixedly installed on different sliding frames 31. By rotating the lead screw 321, the two sliding frames 31 are driven to approach or move away from each other, so as to realize the relative or away movement of the two sliding frames 31. In order to facilitate the rotation of the lead screw 321, a hand wheel 323 is fixed to one end of the lead screw 321. The cable 5 is clamped between the two groups of sliding frames 31.

[0027] The traction device 4 is arranged on the sliding frame 31. Since the sliding frame 31 is arranged in two groups, the traction device 4 is also arranged in two groups. The structures of the traction devices 4 on each group of sliding frames 31 are consistent and oppositely arranged. Therefore, only one of the traction devices 4 will be described in detail below.

[0028] The traction device 4 includes several chain plates 41 and a traction drive device 42 that drives the chain plates 41 to translate. The chain plates 41 on the two sets of sliding frames 31 are arranged opposite each other and the translation process is always synchronized.

[0029] The traction drive device 42 includes two sprockets 421 rotatably mounted on the sliding frame 31 and a sprocket drive motor 422 that drives either sprocket 421 to rotate. The two sprockets 421 are connected by a chain 423, and several chain plates 41 are evenly fixed upward on the rings of the chain 423. The chain 421 is rotated by the sprocket drive motor 422, thereby causing the chain plates 41 to rotate along the chain.

[0030] To protect the traction drive unit 42 and prevent injury, a protective cover 43 is installed on the outside of the traction drive unit 42. The traction drive unit 42 is connected to the controller 1, and the controller 1 controls the operation of the traction drive unit 42.

[0031] The cable 5 is clamped between two chain plates 41. In order to increase the friction between the chain plates 41 and the cable 5 and avoid damaging the cable 5, the chain plates 41 are made of nylon clamps. The chain plates 41 are also provided with anti-slip textures. The anti-slip textures increase the friction between the chain plates 41 and the cable 5, thereby preventing slippage.

[0032] When the chain plate 41 clamps the cable 5 and drags it, in order to avoid the cable 5 from generating hard friction with the lifting platform 22, a guide roller 61 is also rotatably installed on one side of the lifting platform 22. In order to limit the cable 5, there are two guide rollers 61 arranged at the top and bottom, and the cable 5 passes through the middle of the two guide rollers 61.

[0033] like Figure 1 and Figure 2 As shown in the diagram, the workflow of this utility model is as follows:

[0034] One end of cable 5 is passed between the two guide rollers 61 and positioned between the two sliding frames 31. By cranking the handwheel 323, the lead screw 321 is rotated, causing the two sliding frames 31 to move towards each other until the chain plates 41 on both sides of cable 5 clamp the cable 5. Cranking the handwheel 323 is then stopped. Pressing the up button repeatedly causes the lifting drive device 23 to control the lifting platform 22 to rise continuously until the appropriate height is reached. Then, the controller 1 controls the traction drive device 42 to operate, and the chain plates 41 clamp the cable 5 for continuous transport. The electrician can then remove one end of the cable 5 for laying.

[0035] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
