[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0025] Please refer to Figure 2-Figure 7 As shown, the technical solution adopted by the utility model is: an intelligent cable puller with adjustable cable puller gap, comprising a power machine 1, a support frame 2, a transmission device 3 and a cable puller 4, the power machine 1 and the cable puller 4 are respectively arranged on both sides of the support frame 2, and the transmission device 3 is located inside the support frame 2; the power machine 1 drives the cable puller 4 to work through the transmission device 3;
[0026] The wire puller 4 comprises a lifter 41 and two sets of wire pull assemblies 42 arranged in sequence from top to bottom; the lifter 41 comprises a connecting plate 411, a screw rod 412 and a V-shaped rotating plate 413; the connecting plate 411 is fixed on the support frame 2, and both ends of the screw rod 412 are provided with threads with opposite rotation directions and are equipped with studs 414; the V-shaped rotating plate 413 is hinged to the studs 414, and both ends are respectively hinged to the adapter plate 411 and one set of wire pull assemblies 42;
[0027] The wire pulling assembly 42 includes a wire pulling wheel 421, a track 422 and a groove plate 423; the wire pulling wheels 421 are evenly arranged in the groove plate 423 along the length direction of the groove plate 423, one of the wire pulling wheels 421 is connected to the transmission device 3 through a rotating shaft, and the track 422 is arranged around the outer periphery of the wire pulling wheel 421.
[0028] From the above description, it can be seen that by setting up the lifter 41, the two groups of wire pulling assemblies 42 can move relative to each other, forming a structure with adjustable gap; in the lifter 41, since the threads at both ends of the screw 412 are opposite, when the screw 412 is rotated forward or reversely, the V-shaped rotating plates 413 at both ends will open or reduce the angle at the same time, so that the groove plate 423 moves up and down, thereby realizing the adjustable gap of the wire pulling wheel 421 between the two groups of wire pulling assemblies 42; the wire puller 4 can be used for cables of various diameters and has a wider range of applications; in addition, when the surface of the crawler 422 is worn and the pulling force is insufficient, the gap between the wire pulling assemblies 42 can be reduced to ensure that the cable can be pulled.
[0029] More preferably, the transmission device 3 includes a first worm gear 31 and a second worm gear 32 with opposite rotation directions; the first worm gear 31 is slidably connected to the support frame 2; the second worm gear 32 is fixed to the support frame 2 and is located below the first worm gear 31; the second worm gear 32 is a power input shaft; the corresponding worm wheels in the first worm gear 31 and the second worm gear 32 are respectively connected to the rotating shafts of the wire drawing wheels 421 in the two wire drawing assemblies 32; the first worm gear 31 and the second worm gear 32 are respectively connected to the rotating shafts of the wire drawing wheels 421 in the two wire drawing assemblies 32; A gear 33 is provided on the same side of the worm; a transition wheel 34 is provided between the two gears 33; a limit plate 35 is provided on both outer sides of the transition wheel 34, one end of the limit plate 35 is rotatably connected to the two gears 33, and a slide groove 351 is provided on the side of the limit plate 35. The transition wheel 34 is fixed in the slide groove 351 of the limit plates 35 on both sides through a pin shaft 36, and can move in the slide groove 351 along the pin shaft 36; a first compression spring 37 is provided on the outer sleeve of the pin shaft 36, so that the transition wheel 34 is meshed with the two gears 33 respectively.
[0030] From the above description, it can be seen that by setting two sets of first worm gears 31 and second worm gears 32 with opposite rotation directions, the two sets of wire pulling wheels 421 can be rotated in opposite directions, thereby pushing the cable to move; the first worm gear 31 is slidably connected to the support frame 2, so it can be adapted to the wire pulling assembly 41 that can move up and down; at the same time, the first worm gear 31 and the second worm gear 32 are meshed through the gear 33, the transition wheel 34 and the limit plate 35, and the gear meshing method is adopted. Compared with the chain drive, the transmission is more stable and the noise is smaller.
[0031] More preferably, mounting seats 38 are provided on both sides of the first worm gear 31, and a slot is provided on the support frame 2 corresponding to the mounting seats 38. The mounting seats 38 are embedded in the slot and can move up and down along the slot; a fixing plate 39 is provided directly above the mounting seat 38, and the fixing plate 39 is connected to the support frame 2; a guide shaft 3a is provided between the mounting seat 38 and the fixing plate 39, and a second compression spring 3b is provided on the outer sleeve of the guide shaft 3a, so that the transition wheel 34 can better mesh with the two gears 33 respectively.
[0032] From the above description, it can be seen that a structure of sliding connection between the first worm gear 31 and the support frame 2 is disclosed, and the first worm gear 31 is ensured to be more stable during movement through the action of the mounting seat 38 and the guide shaft 3a.
[0033] More preferably, a ring 415 is provided at one end of the screw rod 412 , and the ring 415 and the screw rod 412 are rotatably connected.
[0034] It can be seen from the above description that, through the above arrangement, the operator can use a round rod to be sleeved in the ring 415, and drive the screw 412 to rotate by rotating the round rod, which saves time and effort and makes the operation easier.
[0035] More preferably, a guide wheel 43 is provided at the front end of the wire puller 4, and a circular wire groove 431 is provided in the middle position of the guide wheel 43.
[0036] From the above description, it can be seen that the wire groove 431 can play a certain limiting role, ensuring that the cable entering the wire puller 4 will not be offset, making the operation smoother.
[0037] The working principle of the utility model is as follows: when it is necessary to adjust the gap between the wire pulling assemblies 42, the operator can use a round rod to be sleeved in the ring 415, and rotate the round rod 415 clockwise, so that the V-shaped rotating plates 413 at both ends move outward along the direction of the screw 412, and the angle of the V-shaped rotating plates 413 gradually increases. Since the connecting plate 411 is fixed, the distance between the connecting plate 411 and the groove plate 423 becomes larger, thereby pushing the wire pulling assemblies 42 located above to move downward, that is, the gap between the two groups of wire pulling assemblies 42 becomes smaller; similarly, when the screw 412 rotates counterclockwise, the V-shaped rotating plates 413 at the ends move inward along the direction of the screw 412, and the angle of the V-shaped rotating plates 413 gradually becomes smaller, and the gap between the two groups of wire pulling assemblies 42 increases.
[0038] When the wire pulling assembly 42 moves upward, the rotating shaft of the wire pulling wheel 421 drives the first worm gear 31 to move upward. Under the action of the fixing seat 38 and the guide shaft 3a, the movement of the first worm gear 31 will not be offset; the second compression spring 3b provides a reverse force to make the worm gear meshing more stable; during the movement, the meshing gap between the gear 33 on the side of the first worm gear 31 and the transition wheel 34 becomes larger. Under the action of the first compression spring 37, the transition wheel 34 moves along the pin shaft 36 toward the gear 33 on the side of the second worm gear 32, so that the gap between the two becomes larger, ensuring that the two are better meshed together;
[0039] When the wire pulling assembly 42 moves downward, the gear 33 in the first worm gear 31 will squeeze the transition wheel 34. Under the action of the first compression spring 37, the transition wheel 34 moves along the pin shaft 36 toward the gear 33 on the side of the first worm gear 32, so that the gap between the two becomes smaller, ensuring that the two are better meshed together.
[0040] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
