Description

Technical Field

[0001] The present application relates to the technical field of transmission line stringing construction, and in particular to a traction machine for laying transmission lines. Background Art

[0002] When laying transmission lines, a traction machine and a tension machine are required as auxiliary. The traction machine plays the role of pulling the traction rope to achieve cable laying. The traction machine is usually equipped with a detachable rope reel for reeling in the traction rope.

[0003] At present, the existing rope-collecting drum is detachably connected to the traction machine body through a detachable connecting shaft provided on itself. For example, the Chinese patent with publication number CN213651494U discloses a detachable rope drum for cable recovery. When the rope-collecting drum needs to be replaced, the connection between the traction machine body and the connecting shaft is first released, and the rope-collecting drum that has completed winding is pushed away from the traction machine body. Then, the connecting shaft is removed from the rope-collecting drum, and the removed connecting shaft is installed on the unwound rope-collecting drum. Then, the unwound rope-collecting drum is pushed to the traction machine body, and the unwound rope-collecting drum is reinstalled on the traction machine body to complete the replacement of the rope-collecting drum.

[0004] In the above process of replacing the rope drum, the connecting shaft needs to be disassembled and assembled once to complete the replacement of the rope drum.

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The embodiment of the present application discloses a traction machine for laying power transmission lines. Figure 1 A traction machine for laying power transmission lines includes a traction machine body 1, a rope drum support frame 2, a rope drum 3, a support assembly 4, a rotating support assembly 5 and a power assembly 6.

[0036] Reference Figure 1 The rope drum support frame 2 is connected to the traction machine body 1. Two supporting tubes 21 are fixedly connected to the side of the rope drum support frame 2 away from the traction machine body 1. The two supporting tubes 21 are respectively arranged near the two sides of the rope drum support frame 2. The rope collection drum 3 is arranged on the two supporting tubes 21. The two side tubes of the rope collection drum 3 correspond to the two supporting tubes 21 one by one. The two supporting tubes 21 are used to support the rope collection drum 3.

[0037] Reference Figure 2 , there are two groups of support assemblies 4, which are respectively arranged on the supporting surfaces of the two hosting tubes 21. The support assembly 4 includes a bracket 41, a first support wheel 42, a support cylinder 43 and a second support wheel 44. The bracket 41 is fixedly connected to the middle part of the hosting tube 21, and the first support wheel 42 is rotatably connected to the bracket 41. There are multiple support cylinders 43, which are symmetrically arranged on both sides of the bracket 41. The support cylinders 43 are fixedly connected to the hosting tube 21. There are multiple second support wheels 44, which are rotatably connected to the movable ends of the support cylinders 43 one by one. The first support wheel 42 and all the second support wheels 44 are in contact with the edge side tubes of the rope collecting drum 3 to form an arc-shaped supporting surface, so that the rope collecting drum 3 can be subjected to a stable supporting force.

[0038] The side walls of the first supporting wheel 42 and the second supporting wheel 44 are both concave and arc-shaped, so as to stably support the rope receiving drum 3 .

[0039] Reference Figure 2 and Figure 3 The swivel support assembly 5 is provided with two groups, and corresponds one to one with the two hosting tubes 21. The swivel support assembly 5 includes a connecting frame 51, a swivel support cylinder 52, a support plate 53 and a support block 54. The connecting frame 51 is fixedly connected to the rope drum support frame 2, and the swivel support cylinder 52 is connected to the connecting frame 51. The support plate 53 is rotatably connected to the movable end of the swivel support cylinder 52. There are four support blocks 54, and they are all fixedly connected on the side of the support plate 53 away from the swivel support cylinder 52. The four support blocks 54 are evenly arranged around the rotation axis direction of the support plate 53. The support block 54 is used to be clamped in the support card slot 31 fixed to the rope receiving drum 3. When the support block 54 is clamped in the support card slot 31, the rotation axis of the support plate 53 coincides with the rotation axis of the rope receiving drum 3.

[0040] The power assembly 6 includes a first power member 61, a winding gear 62 and a ring gear 63. The first power member 61 is connected to one of the connecting frames 51, and the winding gear 62 is connected to the first power member 61. The winding gear 62 is externally meshed with the ring gear 63. The ring gear 63 is fixedly connected to the rope receiving drum 3 and is coaxially arranged with the rope receiving drum 3.

[0041] Among them, reference Figure 3 The first power member 61 is a power element capable of outputting rotational power, such as a hydraulic motor, a rotary cylinder or an electric motor. In this application, the first power member 61 is preferably a hydraulic motor, and the winding gear 62 is fixedly connected to the output shaft of the hydraulic motor.

[0042] During use, after the rope receiving drum 3 reels in the traction rope, the rotating support cylinder 52 is retracted so that the supporting block 54 on the support disk 53 can disengage the supporting slot 31 on the rope receiving drum 3, thereby releasing the support of the support disk 53 on the rope receiving drum 3, and then all the supporting cylinders 43 are retracted to release the restriction of the second support wheel 44 on the movement of the rope receiving drum 3, so that the rope receiving drum 3 can move freely relative to the trustee 21, making it easy to disassemble the rope receiving drum 3 from the trustee 21.

[0043] After disassembling the rope collecting drum 3 for winding the traction rope, the rope collecting drum 3 with the unwound traction rope is rolled onto the first support wheel 42 and the second support wheel 44 on the trustee 21, so that the supporting cylinder 43 is extended, so that the first support wheel 42 and all the second support wheels 44 can abut against the edge side tubes of the rope collecting drum 3, so that the trustee 21 can provide a stable supporting force for the rope collecting drum 3, and then the rotating support cylinder 52 is extended, and the rotating support cylinder 52 drives the supporting block 54 on the support disk 53 to be clamped into the support slot 31. Since the support disk 53, the first support wheel 42 and the second support wheel 44 can all rotate, the rope collecting drum 3 can rotate stably under the support of the support disk 53, the first support wheel 42 and the second support wheel 44.

[0044] During the extension of the supporting cylinder 43, the winding gear 62 is engaged with the ring gear 63 on the rope-taking drum 3. The first power member 61 can drive the winding gear 62 to rotate, and the winding gear 62 can drive the ring gear 63 to rotate. The ring gear 63 can drive the rope-taking drum 3 to rotate, so that the rope-taking drum 3 can reel in the traction rope. Since there is no interference between the ring gear 63 and the support drum 53, there is no interference between the support installation and the rotation drive of the rope-taking drum 3.

[0045] Based on the above analysis, the support disc 53 enables the rope collecting disc 3 to rotate stably, and the first support wheel 42 and the second support wheel 44 make it difficult for the rope collecting disc 3 to cause a large load on the rotation support of the support disc 53 after winding the traction rope, so that the support disc 53, the first support wheel 42 and the second support wheel 44 can replace the connecting shaft on the rope collecting disc 3 in the prior art, so that the disassembly and assembly process of the rope collecting disc 3 only needs to push the rope collecting disc 3 to roll, and there is no need to replace the heavy connecting shaft, which reduces the manpower consumed in replacing the rope collecting disc 3 and improves the efficiency of replacing the rope collecting disc 3. At the same time, through the transmission relationship between the winding gear 62 and the ring gear 63, the rope collecting disc 3 can still rotate without installing the connecting shaft, so that the rope collecting disc 3 is easy to disassemble and assemble while not easily affecting its own drive.

[0046] Reference Figure 2 and Figure 3 In order to enable rope-collecting drums 3 of different diameters to be installed on the swivel support assembly 5, the swivel support assembly 5 also includes a support cylinder 55 and a support plate 56. The support cylinder 55 is fixedly connected to the connecting frame 51, and the support plate 56 is fixedly connected to the movable end of the support cylinder 55. The swivel support cylinder 52 is fixedly connected to the support plate 56. The first power member 61 is fixedly connected to the power plate 64, and the power plate 64 is fixedly connected to the support plate 56. The diameters of the ring gears 63 on the rope-collecting drums 3 of different diameters are consistent. When the winding gear 62 is engaged with the ring gear 63, the rotation axis of the support drum 53 coincides with the rotation axis of the rope-collecting drum 3.

[0047] When the rope taking-up drum 3 of different diameters is replaced, since the second support wheel 44 is abutted against the rope taking-up drum 3 under the drive of the support cylinder 43, the rope taking-up drum 3 of different diameters can all accept the stable supporting force of the first support wheel 42 and the second support wheel 44; after the support cylinders 43 on both sides of the bracket 41 are extended symmetrically, the support cylinder 55 is extended, and the support cylinder 55 drives the rotating support cylinder 52 and the winding gear 62 to move synchronously. Since the diameters of the gear rings 63 on the rope taking-up drums 3 of different diameters are consistent, when the winding gear 62 is engaged with the gear ring 63, on the one hand, the gear ring 63 can accept the drive of the winding gear 62, and on the other hand, the height of the support disk 53 can be quickly positioned, so that the rotation axis of the support disk 53 can be quickly adjusted to a position that coincides with the rotation axis of the rope taking-up drum 3, so that the support block 54 can be quickly clamped into the support slot 31 on the rope taking-up drums 3 of different diameters.

[0048] Reference Figure 3 and Figure 4 When the rope collecting drum 3 is supported and adjusted by the supporting cylinder 43, it is necessary to make the elongation states of the supporting cylinders 43 on both sides of the bracket 41 symmetrical, so that the central axis of the rope collecting drum 3 coincides with the rotation axis of the support plate 53. The bracket 41 is fixedly connected with a side plate 45, and the side plate 45 is located in the winding space of the rope collecting drum 3. A clamp rod 46 is hinged on the side plate 45. The clamp rod 46 is bent into an arc shape and is used to fit the edge side tube of the rope collecting drum 3. A padlock hasp 47 is provided between the end of the clamp rod 46 away from the side plate 45 and the side of the bracket 41 away from the side plate 45. The hook body of the padlock hasp 47 is connected to the clamp rod 46, and the lock body of the padlock hasp 47 is connected to the bracket 41.

[0049] Before extending the supporting cylinder 43, rotate the clamp rod 46 so that the clamp rod 46 fits on the edge side tube of the rope receiving drum 3, and hang the lock body of the padlock hasp 47 on the hook body of the padlock hasp 47 to fix the rope receiving drum 3 and the bracket 41. Then, all the supporting cylinders 43 are extended until the second support wheel 44 abuts against the edge side tube of the rope receiving drum 3. Under the condition that the rope receiving drum 3 and the bracket 41 are fixed, the elongation state of the symmetrically arranged supporting cylinders 43 is symmetrical, so that with the assistance of the clamp rod 46, the symmetrical elongation of the supporting cylinders 43 is easy to achieve.

[0050] In addition, before the rope-collecting drum 3 reels in the traction rope, the padlock buckle 47 needs to be opened to avoid hindering the rotation of the rope-collecting drum 3.

[0051] Reference Figure 3 and Figure 5In order to prevent the ring gear 63 from being damaged by collision, an annular protective shell 65 is provided on the ring gear 63, and the protective shell 65 is rotatably connected to the rope-taking drum 3 so that the protective shell 65 is not likely to interfere with the rotation of the rope-taking drum 3. A transmission gap 651 is provided on the outer ring side wall of the protective shell 65, and the transmission gap 651 is located at the meshing position of the winding gear 62 and the ring gear 63. Connecting belts 652 are provided on both sides of the transmission gap 651, and the two connecting belts 652 are fixedly connected to the protective shell 65. The two connecting belts 652 are commonly bolted to a connecting shell 66. The connecting shell 66 is covered on the winding gear 62 and fixedly connected to the power plate 64. The output shaft of the hydraulic motor is rotatably passed through the connecting shell 66. When the rope-taking drum 3 rotates, the connecting belt 652 enables the protective shell 65 to remain stationary.

[0052] When installing the rope-collecting drum 3, the protective shell 65 can effectively protect the gear ring 63 from being bumped, so as to extend the service life of the gear ring 63. The protective shell 65 is rotated so that the transmission gap 651 is opposite to the winding gear 62, so that the gear ring 63 can engage with the winding gear 62 while being protected. The two connecting belts 652 are bolted to the connecting shell 66, so that the protective shell 65 is not easy to rotate with the rope-collecting drum 3, thereby making it difficult for the protective shell 65 to interfere with the meshing transmission of the winding gear 62 and the gear ring 63.

[0053] Reference Figure 5 In order to facilitate the storage of the two connecting belts 652 after the rope collecting drum 3 is disassembled, a Velcro 67 is provided on the two connecting belts 652. The fur surface of the Velcro 67 is fixedly connected to the side of one of the connecting belts 652 away from the transmission notch 651, and the hook surface of the Velcro 67 is fixedly connected to the side of the other connecting belt 652 close to the transmission notch 651.

[0054] After the rope collecting drum 3 is disassembled, the hook surface of the Velcro 67 is adhered to the fleece surface of the Velcro 67 , so that the two connecting belts 652 are easily connected and fixed, thereby making it easy to put the two connecting belts 652 back into place after the rope collecting drum 3 is disassembled.

[0055] In particular, refer to Figure 5 An annular rotating frame 68 is fixedly connected to the inner ring side wall of the protective shell 65, and the rotating frame 68 is rotatably set in the annular rotating groove 69. The rotating groove 69 is fixedly connected to the rope-taking drum 3. The rotating frame 68 and the rotating groove 69 can form a rotating connection structure between the protective shell 65 and the rope-taking drum 3. Since the rotating frame 68 is connected to the inner ring side wall of the protective shell 65, the rotating connection between the protective shell 65 and the rope-taking drum 3 is not easy to interfere with the winding gear 62.

[0056] Reference Figure 2In order to prevent the rope drum 3 from rolling off the trustee 21 during the process of winding the traction rope, the traction machine for laying transmission lines in the present application also includes a protective component 7, and the protective component 7 is provided with two groups, and corresponds one to one with the trustee 21. The protective component 7 is set at the end of the trustee 21 away from the rope drum support frame 2. The protective component 7 is used to prevent the rope drum 3 from rolling off the trustee 21 when the rope drum 3 winds up the traction rope.

[0057] The protective components 7 at the ends of the two tubes 21 work together to prevent the rope-collecting drum 3 from rolling off the tubes 21, thereby improving the safety of the rope-collecting drum 3 during the process of winding the traction rope.

[0058] Specifically, refer to Figure 2 The protection assembly 7 includes a protection block 71 and a push rod 72.

[0059] The protective block 71 is in the shape of a right-angled triangle. The middle part of one of the right-angled sides of the protective block 71 is hinged to the top end of the end face of the hosting tube 21. The inclined side of the protective block 71 is used to prevent the rope collecting drum 3 from rolling off the hosting tube 21. The other right-angled side of the protective block 71 is used to abut against the ground so that the inclined side of the protective block 71 forms a rolling ramp for the rope collecting drum 3.

[0060] The top rod 72 is adapted to be slidably set in the hosting tube 21, and a protective rack 73 is fixedly embedded on the top rod 72. The protective rack 73 is engaged with a protective gear 74. The protective gear 74 is rotatably connected to the outer wall of the hosting tube 21. The engagement point between the protective rack 73 and the protective gear 74 is located at the engagement hole 22 opened on the hosting tube 21. The protective gear 74 is connected to a second power member 75, and the second power member 75 is installed on the hosting tube 21.

[0061] Among them, the second power part 75 is a power element that can output rotational power, such as a hydraulic motor, a rotary cylinder or an electric motor. In this application, the second power part 75 is preferably a motor, and the protective gear 74 is fixedly connected to the output shaft of the motor, and the motor is fixedly connected to the tube 21.

[0062] When the rope collecting drum 3 is installed on the hosting tube 21, the motor can drive the protective gear 74 to rotate, the protective gear 74 can drive the protective rack 73 to move, and the protective rack 73 can drive the top rod 72 to slide, so that the top rod 72 can push the protective block 71 to swing upward, so that the oblique side surface of the protective block 71 can swing to a position close to the rope collecting drum 3 to provide protection for the rope collecting drum 3.

[0063] When the rope collecting drum 3 is disassembled, the motor drives the top rod 72 in reverse to slide, so that the top rod 72 slides into the tube 21, and the protective block 71 swings downward under the action of gravity until the protective block 71 abuts against the ground. At this time, the inclined side surface of the protective block 71 forms a rolling ramp for the rope collecting drum 3, so that the rope collecting drum 3 with the traction rope wound up can easily roll down the tube 21, and the rope collecting drum 3 without the traction rope wound up can easily roll onto the tube 21.

[0064] Reference Figure 2 In order to enable the protective block 71 to form a deceleration effect on the rope-collecting drum 3 with the wound traction rope when it slides down, more than two deceleration ribs 76 are fixedly connected to the oblique side surface of the protective block 71. All the deceleration ribs 76 are arranged along the oblique side surface of the protective block 71, and the length direction of the deceleration rib 76 is parallel to the hinge axis direction of the protective block 71.

[0065] When the rope receiving drum 3 rolls downward from the oblique side surface of the protection block 71 , the deceleration ridge 76 can decelerate the rolling of the rope receiving drum 3 to prevent the rope receiving drum 3 from rolling too fast and causing harm to workers.

[0066] Reference Figure 1 In order to prevent the hosting 21 from hindering the movement of the traction machine body 1, the rope drum support frame 2 is hinged to the traction machine body 1, and a swing assembly 8 is provided between the rope drum support frame 2 and the traction machine body 1. The swing assembly 8 includes a first swing cylinder 81 and a second swing cylinder 82.
