Description

Technical Field

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

[0002] When laying transmission lines, a tractor and a tensioner are needed as aids. The tractor plays a role in pulling the traction rope to achieve cable laying. A detachable rope winding disc is usually provided on the tractor, and the rope winding disc is used to wind the traction rope.

[0003] Currently, the existing rope winding disc realizes detachable connection with the tractor main body through a detachable connection rotating shaft provided on itself. For example, a detachable rope disc for cable recycling disclosed in Chinese Patent No. CN213651494U. When it is necessary to replace the rope winding disc, first release the connection of the tractor main body to the connection rotating shaft, push the completed rope winding disc away from the tractor main body, then detach the connection rotating shaft from the rope winding disc, and install the detached connection rotating shaft on the unwound rope winding disc. Then push the unwound rope winding disc to the tractor main body and reinstall the unwound rope winding disc on the tractor main body to complete the replacement of the rope winding disc.

[0004] During the above process of replacing the rope winding disc, it is necessary to disassemble and assemble the connection rotating shaft once to complete the replacement of the rope winding disc. Due to the large weight of the connection rotating shaft, disassembling and assembling the connection rotating shaft not only requires a large amount of manpower, but also reduces the efficiency of replacing the rope winding disc, which is not conducive to the replacement of the rope winding disc. Summary of the Invention

[0019] The following will further elaborate on this application in conjunction with the attached Figures 1-5 drawings.

[0020] An embodiment of this application discloses a tractor for laying transmission lines. Refer to Figure 1 FIG. 1, a tractor for laying transmission lines includes a tractor main body 1, a rope reel support frame 2, a rope winding reel 3, a support component 4, a rotating support component 5, and a power component 6.

[0021] Refer to Figure 1 FIG. 2, the rope reel support frame 2 is connected to the tractor main body 1. Two trusteeships 21 are fixedly connected to the side of the rope reel support frame 2 away from the tractor main body 1. The two trusteeships 21 are respectively arranged near both sides of the rope reel support frame 2. The rope winding reel 3 is arranged on the two trusteeships 21. The two edge side tubes of the rope winding reel 3 correspond to the two trusteeships 21 one by one. The two trusteeships 21 are used to support the rope winding reel 3.

[0022] Refer to Figure 2 FIG. 3, there are two sets of support components 4, and they are respectively arranged on the supporting surfaces of the two trusteeships 21. The support component 4 includes a bracket 41, a first support wheel 42, a support oil cylinder 43, and a second support wheel 44. The bracket 41 is fixedly connected to the middle of the trusteeship 21. The first support wheel 42 is rotatably connected to the bracket 41. There are multiple support oil cylinders 43, and they are symmetrically arranged on both sides of the bracket 41. The support oil cylinders 43 are fixedly connected to the trusteeship 21. There are multiple second support wheels 44, and they are rotatably connected to the movable ends of the support oil 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 winding reel 3 to form an arc-shaped supporting surface, so that the rope winding reel 3 can receive a stable supporting force.

[0023] Among them, the side walls of the first support wheel 42 and the second support wheel 44 are both concave in an arc shape to facilitate stably supporting the rope winding disc 3.

[0024] Referring to Figure 2 and Figure 3 , there are two sets of swivel support assemblies 5, which correspond to the two cradles 21 one by one. The swivel support assembly 5 includes a connecting frame 51, a swivel support oil cylinder 52, a support disc 53 and a support block 54. The connecting frame 51 is fixedly connected to the rope disc support frame 2. The swivel support oil cylinder 52 is connected to the connecting frame 51. The support disc 53 is rotatably connected to the movable end of the swivel support oil cylinder 52. There are four support blocks 54, and they are all fixedly connected to the side of the support disc 53 away from the swivel support oil cylinder 52. The four support blocks 54 are evenly arranged in the direction of the rotation axis of the support disc 53. The support blocks 54 are used to be clamped in the support slots 31 fixedly connected to the rope winding disc 3. When the support blocks 54 are clamped into the support slots 31, the rotation axis of the support disc 53 coincides with the rotation axis of the rope winding disc 3.

[0025] The power assembly 6 includes a first power member 61, a winding gear 62 and a gear ring 63. The first power member 61 is connected to one of the connecting frames 51. The winding gear 62 is connected to the first power member 61. The winding gear 62 is externally meshed with the gear ring 63. The gear ring 63 is fixedly connected to the rope winding disc 3 and is coaxially arranged with the rope winding disc 3.

[0026] Among them, referring to 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.

[0027] During use, after the rope winding disc 3 winds the towing rope, the swivel support oil cylinder 52 is contracted so that the support blocks 54 on the support disc 53 can be disengaged from the support slots 31 on the rope winding disc 3, releasing the support of the support disc 53 on the rope winding disc 3. Then, all the support oil cylinders 43 are contracted to release the restriction of the second support wheel 44 on the movement of the rope winding disc 3, enabling the rope winding disc 3 to move freely relative to the cradle 21, making it convenient to disassemble the rope winding disc 3 from the cradle 21.

[0028] After removing the rope winding disc 3 of the winding traction rope, roll the rope winding disc 3 without the wound traction rope onto the first support wheel 42 and the second support wheel 44 on the support 21, extend the support oil cylinder 43 so that the first support wheel 42 and all the second support wheels 44 can abut against the edge side pipe of the rope winding disc 3, so that the support 21 provides a stable supporting force for the rope winding disc 3, and then extend the swivel support oil cylinder 52. The swivel support oil cylinder 52 drives the support block 54 on the support disc 53 to be clamped into the support slot 31. Since the support disc 53, the first support wheel 42 and the second support wheel 44 can all rotate, the rope winding disc 3 can rotate stably under the support of the support disc 53, the first support wheel 42 and the second support wheel 44.

[0029] During the process of extending the support oil cylinder 43, engage the winding gear 62 with the gear ring 63 on the rope winding disc 3. The first power member 61 can drive the winding gear 62 to rotate, the winding gear 62 can drive the gear ring 63 to rotate, and the gear ring 63 can drive the rope winding disc 3 to rotate, so that the rope winding disc 3 can wind the traction rope. Since there is no interference between the gear ring 63 and the support disc 53, there is no interference between the support installation and the rotational drive of the rope winding disc 3.

[0030] Based on the above analysis, the support disc 53 enables the rope winding disc 3 to rotate stably. The first support wheel 42 and the second support wheel 44 make it difficult for the rope winding disc 3 to cause a large load on the rotational support of the support disc 53 after winding the traction rope. Thus, the support disc 53, the first support wheel 42 and the second support wheel 44 can replace the connecting rotating shaft on the rope winding disc 3 in the prior art. The disassembly and assembly process of the rope winding disc 3 only requires rolling the rope winding disc 3, without replacing the heavy connecting rotating shaft, reducing the labor consumed for replacing the rope winding disc 3 and improving the efficiency of replacing the rope winding disc 3. At the same time, through the transmission relationship between the winding gear 62 and the gear ring 63, the rope winding disc 3 can still rotate without installing the connecting rotating shaft, making the rope winding disc 3 easy to disassemble and assemble and not easily affecting its own drive.

[0031] Refer to Figure 2 and Figure 3 In order to enable rope winding discs 3 with different diameters to be installed on the swivel support assembly 5, the swivel support assembly 5 further includes a support oil cylinder 55 and a support plate 56. The support oil cylinder 55 is fixedly connected to the connecting frame 51, the support plate 56 is fixedly connected to the movable end of the support oil cylinder 55, the swivel support oil cylinder 52 is fixedly connected to the support plate 56, the first power member 61 is fixedly connected with a power plate 64, and the power plate 64 is fixedly connected to the support plate 56. The diameters of the gear rings 63 on the rope winding discs 3 with different diameters are the same. When the winding gear 62 is engaged with the gear ring 63, the rotation axis of the support disc 53 coincides with the rotation axis of the rope winding disc 3.

[0032] When replacing the rope winding disc 3 with different diameters, since the second support wheel 44 abuts against the rope winding disc 3 under the drive of the support oil cylinder 43, the rope winding discs 3 with different diameters can all receive the stable supporting force of the first support wheel 42 and the second support wheel 44; after the support oil cylinders 43 on both sides of the bracket 41 extend symmetrically, the support oil cylinder 55 extends. The support oil cylinder 55 drives the swivel support oil cylinder 52 and the winding gear 62 to move synchronously. Since the diameters of the toothed rings 63 on the rope winding discs 3 with different diameters are the same, when the winding gear 62 meshes with the toothed ring 63, on the one hand, the toothed ring 63 can receive the drive of the winding gear 62, and on the other hand, the height of the support disc 53 can be quickly positioned, so that the rotation axis of the support disc 53 can be easily adjusted to coincide with the rotation axis of the rope winding disc 3, so that the support block 54 can be quickly clamped into the support slot 31 on the rope winding disc 3 with different diameters.

[0033] Referring to Figure 3 and Figure 4 , when adjusting the support of the rope winding disc 3 through the support oil cylinder 43, it is necessary to make the extended states of the support oil cylinders 43 on both sides of the bracket 41 symmetrical, so that the central axis of the rope winding disc 3 coincides with the rotation axis of the support disc 53. A side plate 45 is fixedly connected to the bracket 41. The side plate 45 is located in the winding space of the rope winding disc 3. A clamp rod 46 is hinged on the side plate 45. The clamp rod 46 is bent in an arc shape and is used to fit and hoop on the edge side pipe of the rope winding disc 3. A padlock buckle 47 is arranged between the end of the clamp rod 46 far from the side plate 45 and the side of the bracket 41 far from the side plate 45. The hook body of the padlock buckle 47 is connected to the clamp rod 46, and the lock body of the padlock buckle 47 is connected to the bracket 41.

[0034] Before the support oil cylinder 43 extends, rotate the clamp rod 46 to make the clamp rod 46 fit on the edge side pipe of the rope winding disc 3, and hang the lock body of the padlock buckle 47 on the hook body of the padlock buckle 47 to fix the rope winding disc 3 to the bracket 41. Then make all the support oil cylinders 43 extend until the second support wheel 44 abuts against the edge side pipe of the rope winding disc 3. Under the condition that the rope winding disc 3 is fixed to the bracket 41, the extended states of the symmetrically arranged support oil cylinders 43 are symmetrical. Thus, with the assistance of the clamp rod 46, the symmetric extension of the support oil cylinder 43 is easy to achieve.

[0035] In addition, before the rope winding disc 3 winds the towing rope, it is necessary to open the padlock buckle 47 to avoid hindering the rotation of the rope winding disc 3.

[0036] Referring to Figure 3 and Figure 5, in order to prevent the gear ring 63 from being easily damaged by bumps, an annular protective shell 65 is provided over the gear ring 63. The protective shell 65 is rotatably connected to the rope winding disc 3 so that the protective shell 65 is not likely to interfere with the rotation of the rope winding disc 3. A transmission notch 651 is formed in the outer ring side wall of the protective shell 65, and the transmission notch 651 is located at the meshing position of the winding gear 62 and the gear ring 63. Connecting belts 652 are arranged on both sides of the transmission notch 651, and both connecting belts 652 are fixedly connected to the protective shell 65. A connecting shell 66 is bolted jointly by the two connecting belts 652. The connecting shell 66 covers the winding gear 62 and is fixedly connected to the power plate 64. The output shaft of the hydraulic motor rotatably penetrates through the connecting shell 66. When the rope winding disc 3 rotates, the connecting belt 652 enables the protective shell 65 to remain stationary.

[0037] When installing the rope winding disc 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. Rotate the protective shell 65 to align the transmission notch 651 with the winding gear 62, so that the gear ring 63 can be meshed with the winding gear 62 under protection. Bolt the two connecting belts 652 to the connecting shell 66, so that the protective shell 65 is not likely to rotate with the rope winding disc 3, thereby preventing the protective shell 65 from interfering with the meshing transmission of the winding gear 62 and the gear ring 63.

[0038] Refer to Figure 5 , in order to facilitate the arrangement of the two connecting belts 652 after the rope winding disc 3 is disassembled, a magic tape 67 is provided jointly on the two connecting belts 652. The rough surface of the magic tape 67 is fixedly connected to one side of one connecting belt 652 away from the transmission notch 651, and the hook surface of the magic tape 67 is fixedly connected to one side of the other connecting belt 652 close to the transmission notch 651.

[0039] After the rope winding disc 3 is disassembled, stick the hook surface of the magic tape 67 to the rough surface of the magic tape 67, so that the two connecting belts 652 are easy to connect and fix, thereby facilitating the arrangement of the two connecting belts 652 after the rope winding disc 3 is disassembled.

[0040] Particularly, refer to Figure 5 , an annular rotating frame 68 is fixedly connected to the inner ring side wall of the protective shell 65. The rotating frame 68 is rotatably arranged in an annular rotating groove 69, and the rotating groove 69 is fixedly connected to the rope winding disc 3. A rotating connection structure between the protective shell 65 and the rope winding disc 3 can be formed through the rotating frame 68 and the rotating groove 69. 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 winding disc 3 is not likely to interfere with the winding gear 62.

[0041] Refer to Figure 2, in order to prevent the rope take-up reel 3 from easily rolling off the support 21 during the process of winding the traction rope, a traction machine for transmission line laying in this application further includes a protection component 7. There are two sets of protection components 7, which correspond to the supports 21 one by one. The protection component 7 is arranged at one end of the support 21 away from the rope reel support frame 2. The protection component 7 is used to block the rope take-up reel 3 from rolling off the support 21 when the rope take-up reel 3 winds the traction rope.

[0042] The protection components 7 at the two ends of the two supports 21 work together to block the rope take-up reel 3 from rolling off the support 21, improving the safety of the rope take-up reel 3 during the process of winding the traction rope.

[0043] Specifically, referring to Figure 2 , the protection component 7 includes a protection block 71 and a top rod 72.

[0044] The protection block 71 is in the shape of a right-angled triangle. The middle of one of the right-angled sides of the protection block 71 is hinged to the top end of the end face of the support 21. The inclined side of the protection block 71 is used to block the rope take-up reel 3 from rolling off the support 21. The other right-angled side of the protection block 71 is used to abut against the ground so that the inclined side of the protection block 71 forms a rolling ramp for the rope take-up reel 3.

[0045] The top rod 72 is slidably arranged in the support 21 in a matching manner. A protection rack 73 is fixedly embedded on the top rod 72. The protection rack 73 meshes with a protection gear 74. The protection gear 74 is rotatably connected to the outer side wall of the support 21. The meshing position of the protection rack 73 and the protection gear 74 is at the meshing hole 22 opened on the support 21. The protection gear 74 is connected to a second power component 75, and the second power component 75 is installed on the support 21.

[0046] Among them, the second power component 75 is a power element capable of outputting rotational power, such as a hydraulic motor, a rotary cylinder or a motor. In this application, the second power component 75 is preferably a motor. The protection gear 74 is fixedly connected to the output shaft of the motor, and the motor is fixedly connected to the support 21.

[0047] When the rope take-up reel 3 is installed on the support 21, the motor can drive the protection gear 74 to rotate. The protection gear 74 can drive the protection rack 73 to move. The protection rack 73 can drive the top rod 72 to slide, so that the top rod 72 can push the protection block 71 to swing upward, so that the inclined side of the protection block 71 can swing to a position close to the rope take-up reel 3 to form protection for the rope take-up reel 3.

[0048] When disassembling the rope winding disc 3, the motor drives the ejector rod 72 to slide in the reverse direction, causing the ejector rod 72 to slide into the support 21. Under the action of gravity, the protective block 71 swings downward until the protective block 71 abuts against the ground. At this time, the inclined side of the protective block 71 forms a rolling ramp for the rope winding disc 3, so that the rope winding disc 3 wound with the traction rope is convenient to roll down the support 21, and the rope winding disc 3 without the traction rope wound is convenient to roll onto the support 21.

[0049] Referring to Figure 2 , in order to enable the protective block 71 to form a decelerating effect on the rope winding disc 3 wound with the traction rope during the downward sliding, two or more decelerating ridges 76 are fixedly connected to the inclined side of the protective block 71. All the decelerating ridges 76 are arranged along the inclined side of the protective block 71, and the length direction of the decelerating ridges 76 is parallel to the hinge axis direction of the protective block 71.

[0050] When the rope winding disc 3 rolls downward from the inclined side of the protective block 71, the decelerating ridges 76 can form a decelerating effect on the rolling of the rope winding disc 3, so as to prevent the rope winding disc 3 from rolling too fast and causing harm to the workers.

[0051] Referring to Figure 1 , in order to prevent the support 21 from easily hindering the movement of the traction machine main body 1, the rope disc support frame 2 is hinged to the traction machine main body 1, and a swing assembly 8 is arranged between the rope disc support frame 2 and the traction machine main body 1. The swing assembly 8 includes a first swing oil cylinder 81 and a second swing oil cylinder 82.

[0052] There are two first swing oil cylinders 81 and two second swing oil cylinders 82, and they are all in one-to-one correspondence with the support 21. The first swing oil cylinder 81 and the second swing oil cylinder 82 are arranged along the direction away from the hinge of the rope disc support frame 2. The first swing oil cylinder 81 and the second swing oil cylinder 82 are both hinged to the traction machine main body 1, and the movable ends of the first swing oil cylinder 81 and the second swing oil cylinder 82 are both hinged to the rope disc support frame 2.

[0053] When moving the traction machine main body 1, extend the first swing oil cylinder 81 and the second swing oil cylinder 82. The first swing oil cylinder 81 and the second swing oil cylinder 82 can push the rope disc support frame 2 and the support 21 to swing upward, so that the support 21 is not easy to hinder the movement of the traction machine main body 1.

[0054] In addition, when the rope winding disc 3 winds the traction rope, it is necessary to adjust the support 21 to be in a horizontal state through the first swing oil cylinder 81 and the second swing oil cylinder 82, so that the first support wheel 42 and all the second support wheels 44 are in the best state of supporting the rope winding disc 3.

[0055] The implementation principle of a tractor for transmission line laying in an embodiment of the present application is as follows: During use, the swivel support cylinder 52 is contracted to release the fixation of the support block 54 on the rope take-up reel 3, and then the support cylinder 43 is contracted to release the restriction of the second support wheel 44 on the movement of the rope take-up reel 3. Then, the rope take-up reel 3 wound with the traction rope is pushed to roll down from the support 21 along the protective block 71, completing the disassembly of the rope take-up reel 3 wound with the traction rope; the rope take-up reel 3 without the traction rope wound is pushed along the protective block 71 onto the support 21. With the assistance of the clamp rod 46, the support cylinders 43 on both sides of the bracket 41 are symmetrically extended so that the first support wheel 42 and the second support wheel 44 stably support the rope take-up reel 3. The support cylinder 55 is extended until the winding gear 62 meshes with the gear ring 63 to position the height of the support disk 53. The swivel support cylinder 52 is extended so that the support block 54 is clamped into the support slot 31, enabling the support disk 53 to rotatably support the rope take-up reel 3. Thus, the disassembly and assembly of the rope take-up reel 3 do not require replacing a heavy connecting rotating shaft, reducing the labor cost for replacing the rope take-up reel 3 and improving the efficiency of replacing the rope take-up reel 3.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
