Description

Technical Field

[0002] Under normal circumstances, for transportation considerations, cables are generally fixed on I-shaped trays. When in use, they are first lifted to the specified position by a crane. When in use, such as when laying cables on the ground, the cables must be first installed on the pay-off rack together with the I-shaped tray, and then the pay-off operation can be performed. Normally, lifting equipment is also required in the process of installing the cables on the pay-off rack, but most outdoor lifting equipment is priced by time, and the laying of cables is extremely time-consuming.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figures 1 to 8 A line lifting and handling equipment suitable for communication engineering line construction includes a vehicle body 1, a jacking mechanism is symmetrically arranged on the vehicle body 1, and the jacking mechanism includes a lifting seat 2 and a hydraulic cylinder 3, a cylinder body of the hydraulic cylinder 3 is fixedly connected to the vehicle body 1, and a hydraulic column of the hydraulic cylinder 3 is fixedly connected to the lifting seat 2, the lifting seat 2 is located on the upper side of the vehicle body 1, and a bracket 4 is arranged on the lifting seat 2, and an opening groove 401 is arranged on the top of the bracket 4;

[0032] A cable drum 5 is provided between the supporting mechanisms. The cable drum 5 is in an I-shape, and a limiting shaft 6 is provided in the middle of the cable drum 5. The limiting shaft 6 is a hollow structure, and a center rod 7 is inserted in the limiting shaft 6. Both ends of the center rod 7 are respectively overlapped on a bracket 4. A driving mechanism for driving the center rod 7 to rotate is provided on one of the lifting seats 2, and the driving mechanism includes a first support rod 8, and a driving motor 9 is provided on the first support rod 8. A connecting component for connecting with the center rod 7 is provided on the output shaft of the driving motor 9.

[0033] The connecting assembly includes a fixed seat 10, which is fixedly connected to the first support rod 8, and a rotatable connecting seat 11 is provided in the fixed seat 10, one end of the connecting seat 11 is fixedly connected to the output shaft of the driving motor 9, and the other end of the connecting seat 11 is provided with a fixing groove 12, and a plurality of connecting claws 13 are provided in the fixing groove 12, the connecting claws 13 are elastically connected to the connecting seat 11 through a rebound spring 35, and one end of the connecting claw 13 is provided with an inclined surface, and both ends of the center rod 7 are provided with limit grooves 701, and the limit grooves 701 are arranged on the center rod 7.

[0034] A hanging rod 101 is provided at one end of the vehicle body 1 , and supporting feet 102 are provided on both sides of the vehicle body 1 , and the supporting feet 102 are screwed to the vehicle body 1 through threads.

[0035] By providing a vehicle body 1 with a jacking mechanism, during operation, the center rod 7 is first inserted into the limiting shaft 6, and then the jacking mechanism is moved to the bottom of the center rod 7 by moving the vehicle body 1, and then the hydraulic cylinder 3 is started. Under the push of the hydraulic cylinder 3, the jacking mechanism moves upward, and an opening groove 401 that matches the center rod 7 is provided on the bracket 4, and the center rod 7 can be supported by the bracket 4. A connecting component is provided on the outer side of the bracket 4, which includes a fixed seat 10, a connecting seat 11 is provided in the fixed seat 10, and a plurality of connecting claws 13 are provided on the connecting seat 11. Correspondingly, a plurality of limiting grooves 701 are provided at the end of the center rod 7. By moving the connecting seat 11, the connecting claws 13 can be inserted into the limiting grooves 701 from the end of the center rod 7, and then the driving motor 9 is started. The driving motor 9 can drive the connecting seat 11 and the center rod 7 to rotate, thereby causing the limiting shaft 6 and the cable drum 5 to rotate, so as to achieve the purpose of automatic wire release and save more effort.

[0036] This technical solution provides a vehicle body 1 with a jacking mechanism. When the cable drum 5 needs to be lifted, one person can operate the vehicle body 1 to complete the task of docking the jacking mechanism with the center rod 7 on the cable drum 5. Subsequently, the lifting operation of the cable drum can be completed quickly, efficiently and safely through the jacking mechanism.

[0037] A hanging rod 101 is provided at one end of the vehicle body 1, and the vehicle body 1 can be conveniently dragged to move by the hanging rod 101. When the vehicle body 1 lifts up the cable drum 5 through the jacking mechanism, the cable drum 5 does not need to be placed on the pay-off rack, but the vehicle body 1 can be directly used as a pay-off rack. At this time, by twisting the supporting legs 102, the supporting legs 102 can be caused to contact the ground, thereby improving the stability of the vehicle body 1 when paying out the wire, and the cable drum 5 can be loaded on the vehicle body 1, which is also more convenient to move.

[0038] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8A slider 14 is provided at the bottom of the first support rod 8, and the slider 14 is slidably connected to the lifting seat 2 through a slide groove 15. A tension spring 16 and a clamping block 17 are provided inside the lifting seat 2, and one end of the tension spring 16 is fixedly connected to the slider 14. The slider 14 is provided with a clamping hole 1401 that matches the clamping block 17.

[0039] An adjusting rod 19 is also provided in the lifting seat 2 . A wedge block 37 is provided at one end of the adjusting rod 19 , and the other end of the adjusting rod 19 is fixedly connected to the clamping block 17 . The adjusting rod 19 is elastically connected to the lifting seat 2 via a first spring 18 .

[0040] A second support rod 20 is provided at the lower side of the bracket 4 , and one end of the second support rod 20 is fixedly connected to the lifting seat 2 . A second spring 21 is provided on the second support rod 20 . One end of the bracket 4 passes through the second support rod 20 and contacts the inclined surface of the adjusting rod 19 .

[0041] In order to improve the convenience of operating the cable drum 5, the present application further provides a driving motor 9, which is connected to the center rod 7 through a connecting assembly. Driven by the driving motor 9, the center rod 7, the limit shaft 6, and the cable drum 5 can be driven to rotate, thereby achieving the purpose of automatic wire release. In order to improve the convenience of connecting the driving motor with the center rod 7, the present technical solution provides a movable connecting assembly, which is arranged on the first support rod 8. The first support rod 8 can slide on the lifting seat 2 through the slider 14. Correspondingly, an adjusting rod 19 and a clamping block 17 are also provided in the lifting seat 2. A clamping hole 1401 that matches the clamping block 17 is provided on the slider 14. The clamping block 17 is fixed on the adjusting rod 19, and the adjusting rod 19 is elastically connected to the lifting seat 2 through the first spring 18. At the same time, a wedge block 37 is provided at one end of the adjusting rod 19;

[0042] In the initial state, the height of the bracket 4 is higher than the connecting seat 11. When the opening groove 401 on the bracket 4 is aligned with the center rod 7, the hydraulic cylinder 3 pushes the lifting seat 2 upward. As the lifting seat 2 moves, the bracket 4 contacts the center rod 7. Affected by the weight of the center rod 7 and the cable drum 5, the bracket 4 overcomes the resistance of the second spring 21 and slides relative to the second support rod 20. During this process, the bottom end of the bracket 4 contacts the wedge block 37 on the adjusting rod 19, thereby pushing the adjusting rod 19 to move to the side away from the slider 14. Driven by the adjusting rod 19, the clamping block 17 is pulled out of the clamping hole 1401. After losing the limit of the clamping block 17, the slider 14 moves toward the bracket 4 under the push of the tension spring 16, thereby causing the connecting seat 11 to engage with the center rod 7.

[0043] When the connecting seat 11 moves along the axial direction of the center rod 7, if the position of the connecting claw 13 is exactly opposite to the limiting groove 701, the connecting claw 13 can be directly inserted into the limiting groove 701, and then the driving motor 9 drives the connecting claw 13, the connecting seat 11 and the center rod 7 to rotate. If the position of the connecting claw 13 is staggered with the limiting groove 701, the technical solution provides an inclined surface at the end of the connecting claw 13, and at the same time, a groove for accommodating the connecting claw 13 is opened on the inner wall of the connecting seat 11. During the collision process, the connecting claw 13 overcomes the resistance of the rebound spring 35 and retracts into the groove. As the connecting seat 11 rotates, when the connecting claw 13 reaches the position of the limiting groove 701, the connecting claw 13 can be inserted into the limiting groove 701 under the push of the rebound spring 35, thereby completing the connection with the center rod 7. The technical solution does not require manual adjustment, and can automatically complete the connection between the driving motor 9, the connecting assembly and the center rod 7, greatly reducing the labor intensity of the workers.

[0044] This technical solution cleverly utilizes the resistance generated in the process of supporting the cable drum 5, and cooperates with the bracket 4, the second support rod 20 and the lifting seat 2 with the adjusting rod 19, the slider 14, and the block 17 to automatically complete the connection between the connecting component and the center rod 7, with a higher degree of automation, effectively reducing the labor intensity of the operator.

[0045] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 The center rod 7 is a hollow structure, and a first limiting mechanism is symmetrically arranged inside the center rod 7. The first limiting mechanism includes a push rod 22 and a fixed ring 23. The fixed ring 23 is provided with a plurality of extension columns 24, and the extension columns 24 are elastically connected to the fixed ring 23 through a limiting spring 25. The push rod 22 is slidably connected to the center rod 7, and one end of the push rod 22 is in contact with the extension column 24. The end of the push rod 22 close to the extension column 24 is in a cone shape. An opening 702 is provided on the center rod 7 for the extension column 24 to enter and exit, and a plurality of limiting teeth 601 are provided on the inner wall of the limiting shaft 6.

[0046] A push head 26 for limiting the push rod 22 is provided in the connection seat 11 , and the push head 26 is elastically connected to the connection seat 11 via a third spring 27 .

[0047] Cables of different specifications will be fixed with cable reels 5 of different specifications. In order to cope with different cable reels 5, the present technical solution improves the center rod 7, and a first limiting mechanism is set inside the center rod 7. Correspondingly, a limiting tooth 601 used in conjunction with the limiting shaft 6 is set on the inner wall. The first limiting mechanism is composed of a top rod 22 and a fixing ring 23. An extension column 24 with an adjustable position is provided on the fixing ring 23. Under normal circumstances, the extension column 24 is retracted into the center rod 7. When the connecting seat 11 approaches the center rod 7, the top head 26 inside the connecting seat 11 collides with the top rod 22 in the center rod 7, and the top rod 22 moves toward the fixing ring 23. Under the push of the top rod 22, the extension column 24 extends out from the opening 702 on the center rod 7. In this way, when the center rod 7 rotates, it can adapt to cable reels 5 with limiting shafts 6 of different sizes through the extension column 24, and the scope of use is wider.

[0048] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 8 A second limiting mechanism for limiting the top head 26 is also provided in the connecting seat 11, and the second limiting mechanism includes a first limiting plate 28 and a second limiting plate 29. A guide rod 30 is provided on one side of the first limiting plate 28. The guide rod 30 is fixedly connected to the connecting seat 11, and the guide rod 30 is slidably connected to the first limiting plate 28. The first limiting plate 28 is elastically connected to the connecting seat 11 through a fourth spring 31, and a limiting protrusion 2801 is provided on the lower side of the first limiting plate 28;

[0049] A receiving groove 36 is provided at the gap of the connecting claw 13, the second limiting plate 29 is located in the receiving groove 36, and the second limiting plate 29 is elastically connected to the connecting seat 11 through the fifth spring 32, and a guide block 33 is provided at one end of the second limiting plate 29 close to the first limiting plate 28, the guide block 33 is slidably connected to the connecting seat 11, one end of the guide block 33 is in contact with the first limiting plate 28, and the other end of the guide block 33 is in contact with the second limiting plate 29.

[0050] A plurality of limiting teeth 34 are provided on one side of the top head 26 close to the first limiting plate 28 , and the position of the limiting teeth 34 is opposite to the limiting protrusion 2801 .

[0051] In order to improve the stability of the first limiting mechanism, the technical solution is provided with a second limiting mechanism in the connecting seat 11, which includes a first limiting plate 28 and a second limiting plate 29. The first limiting plate 28 is elastically connected to the connecting seat 11, and the second limiting plate 29 is elastically installed in the accommodating groove 36. When connected, the second limiting plate 29 will also be inserted into the limiting groove 701. A plurality of fifth springs 32 are provided on the side of the second limiting plate 29. Since the length of the fifth spring 32 is relatively long, the second limiting plate 29 can be displaced in the left and right and up and down directions. In the initial state, the second limiting plate 29 and the guide block 33 are on the same central axis. When the first limiting plate 29 is in the same central axis, the second limiting plate 29 and the guide block 33 are in the same central axis. After the second limit plate 29 is inserted into the limit groove 701, as the connecting seat 11 rotates, the second limit plate 29 and the guide block 33 slide relative to each other, and the guide block 33 moves toward the direction of the top head 26 under the push of the second limit plate 29. Under the push of the guide block 33, the first limit plate 28 moves toward the limit teeth 34. At this time, the limit protrusion 2801 on the first limit plate 28 will be inserted into the gap of the limit teeth 34. If the top head 26 is forced to retreat, it will also move with the limit teeth 34. At this time, the limit protrusion 2801 will limit the limit teeth 34, and then indirectly limit the top head 26.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
