Description

Technical Field

[0001] The utility model belongs to the technical field of logistics equipment, and specifically relates to a synchronous lifting device for a festoon mechanism. Background Art

[0002] The festoon cable was originally designed for power transmission and signal transmission in a festoon system to control cranes, hoists, or any equipment with lateral movement. The festoon cable is a highly flexible mobile cable suitable for various occasions that require frequent bending and reciprocating motion, such as cable festoon trolleys, gantry cranes, mobile cranes, gantry conveyors, rapid conveyor systems, high-speed extraction equipment, and machine tools. Its characteristics include a unique flexible circular structure design that can withstand medium stress and can be used in various environments. The cable structure of the festoon cable is simple and easy to maintain, especially suitable for these equipment that require frequent bending and reciprocating motion.

[0003] The festoon system (also known as a cable trolley) is a mature form of mobile power supply. Therefore, the festoon cable is an important part of the festoon system for realizing power transmission and signal control. The festoon system is a broader concept, including multiple parts such as cable trolleys, cable guiding devices, and cable protection devices, which provide a comprehensive power supply and signal transmission solution for mobile equipment.

[0004] When replacing vulnerable parts such as wheels during the operation of the cable trolley along the cable guiding device, a certain gap needs to be maintained between the cable trolley and the cable guiding device. In the prior art, in the device for maintaining the gap between the cable trolley and the cable guiding device, there is a problem of complex length adjustment for the lateral adjusting rod spanning the cable trolley or the cable guiding device, which further increases the complexity and workload of the work. Summary of the Utility Model

[0005] To solve the problems of complex and cumbersome operation and large workload in adjusting the lateral length of the device, the utility model provides a synchronous lifting device for a festoon mechanism that helps reduce the complexity of the operation.

[0006] The utility model is realized by the following technical solutions:

[0007] A synchronous lifting device for a trailing cable mechanism, comprising two horizontally telescopic support components and two vertically telescopic support components arranged between the two horizontally telescopic support components; the two vertically telescopic support components are respectively detachably connected to the same end of the two horizontally telescopic support components. The horizontally telescopic support component includes a horizontal support pipe, and nuts one are respectively provided at both ends of the horizontal support pipe. A screw one and a screw two are respectively threadedly connected in the two nuts one, and the thread directions of the screw one and the screw two are opposite; the screw one and the screw two are slidably installed at both ends of a guide rod.

[0008] A guide rod is provided between the screw one and the screw two. By rotating one of the nuts one, the length adjustment of the overall horizontally telescopic support component can be controlled; this helps to reduce the complexity of operation, save the workload, and improve efficiency.

[0009] A further improvement of the present utility model is that the cross-section of the above-mentioned guide rod is a non-circular structure, and holes matching the guide rod are respectively formed on the screw one and the screw two. This helps to avoid the problem that the screw one or the screw two rotates circumferentially relative to the guide rod, and thus ensures the length adjustment of the horizontally support component.

[0010] A further improvement of the present utility model is that a connecting pipe is rotatably provided in the above-mentioned horizontal support pipe, and the two nuts one are respectively arranged at both ends of the connecting pipe. By means of the connecting pipe provided in the horizontal support pipe, the synchronous rotation of the two nuts one can be realized.

[0011] A further improvement of the present utility model is that the above-mentioned horizontal support pipe is provided with positioning protrusions; there are two positioning protrusions, and the two positioning protrusions are symmetrically arranged on both sides of the center of the horizontal support pipe. The cable pulley or the cable guiding device can be clamped and fixed through the positioning protrusions, and thus an installation guide is provided for the installation position of the horizontally support component thereon.

[0012] A further improvement of the present utility model is that the above-mentioned horizontally telescopic support component further includes two hanging rings, and the two hanging rings are respectively connected to the opposite ends of the screw one and the screw two.

[0013] A further improvement of the present utility model is that the above-mentioned vertically telescopic support component includes an adjustment frame. The adjustment frame is integrally rectangular, and nuts two are provided on the short sides of the adjustment frame. A screw three and a screw four are respectively threadedly connected in the two nuts two; the opposite ends of the screw three and the screw four are respectively connected with elastic hooks that can be connected to the hanging rings. By adjusting the extension lengths of the screw three and the screw four relative to the adjustment frame, the length adjustment of the vertically telescopic component is completed, and the elastic hooks are connected to the hanging rings.

[0014] A further improvement of the present utility model is that the thread directions of the above-mentioned screw rod three and screw rod four are opposite. This helps to achieve that after the elastic hook is connected to the hanging ring, the length adjustment operation of the vertical telescopic support assembly can be completed only by rotating the adjustment frame for adjustment.

[0015] As can be seen from the above technical solutions, the beneficial effects of the present utility model are as follows: A guide rod is provided between the screw rod one and the screw rod two. By rotating one of the nuts one, the length adjustment of the overall horizontal telescopic support assembly can be controlled; this helps to reduce the complexity of the operation, save the workload, and improve the efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the purpose, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this patent.

[0022] As shown in the atta Figures 1-3As shown in the figure, a synchronous lifting device for a trailing cable mechanism includes two horizontally telescopic support assemblies 10 and two vertically telescopic support assemblies 20 arranged between the two horizontally telescopic support assemblies 10; the two vertically telescopic support assemblies 20 are respectively detachably connected to the same ends of the two horizontally telescopic support assemblies 10.

[0023] The horizontally telescopic support assembly 10 includes a horizontal support tube 11, and nuts 13 are respectively provided at both ends of the horizontal support tube 11. A first screw 14 and a second screw 15 are respectively threadedly connected in the two nuts 13, and the thread directions of the first screw 14 and the second screw 15 are opposite; the first screw 14 and the second screw 15 are slidably installed at both ends of a guide rod 16. The cross-section of the guide rod 16 is a non-circular structure, and holes matching the guide rod 16 are respectively formed in the first screw 14 and the second screw 15. This helps to avoid the problem that the first screw 14 or the second screw 15 rotates circumferentially relative to the guide rod 16, thereby ensuring the adjustment of the length of the horizontal support assembly. The specific operation of synchronously adjusting the first screw 14 and the second screw 15 in this step is: after grasping the first screw 14 or the second screw 15, rotate the horizontal support tube 11 or the nut 13 to complete the synchronous adjustment of the first screw 14 and the second screw 15 relative to the horizontal support tube 11.

[0024] A connecting tube 12 is rotatably arranged in the horizontal support tube 11, and both ends of the connecting tube 12 are connected to the horizontal support tube 11 through bearings 121; the two nuts 13 are respectively arranged at both ends of the connecting tube 12. By providing the connecting tube 12 in the horizontal support tube 11, it helps to achieve the synchronous rotation of the two nuts 13. A positioning protrusion 18 is provided on the horizontal support tube 11; there are two positioning protrusions 18, and the two positioning protrusions 18 are symmetrically arranged on both sides of the center of the horizontal support tube 11. The cable trolley or the cable guiding device can be clamped and fixed through the positioning protrusion 18, thereby providing an installation guide for the position installation of the horizontal support assembly thereon. The specific operation of synchronously adjusting the first screw 14 and the second screw 15 in this step is: only by rotating one of the nuts 13 relative to the horizontal support tube 11, the two nuts 13 can achieve synchronous rotation under the connection action of the connecting tube 12, and then under the cooperation of the guide rod 16, the first screw 14 and the second screw 15 can be synchronously telescoped and adjusted relative to the horizontal support tube 11.

[0025] The horizontally telescopic support assembly 10 further includes two hanging rings 17, and the two hanging rings 17 are respectively connected to the opposite ends of the first screw 14 and the second screw 15.

[0026] The vertical telescopic support assembly 20 includes an adjustment frame 21, which is integrally rectangular in structure, and nuts two 22 are provided on the short sides of the adjustment frame 21. A screw rod three 23 and a screw rod four 24 are respectively threadedly connected in the two nuts two 22; the opposite ends of the screw rod three 23 and the screw rod four 24 are respectively connected with elastic hooks 25 that can be connected to the hanging rings 17. By adjusting the extension lengths of the screw rod three 23 and the screw rod four 24 relative to the adjustment frame 21, the length adjustment of the vertical telescopic assembly is completed, and the elastic hooks 25 are connected to the hanging rings 17.

[0027] The screw threads of the screw rod three 23 and the screw rod four 24 have opposite helix directions. This helps to achieve that after the elastic hook 25 is connected to the hanging ring 17, only by rotating and adjusting the adjustment frame 21, the length adjustment operation of the vertical telescopic support assembly 20 can be completed.

[0028] In the synchronous lifting device of the trailing cable mechanism of the present invention, a guide rod is provided between the screw rod one and the screw rod two. By rotating one of the nuts one, the length adjustment of the overall horizontal telescopic support assembly can be controlled; this helps to reduce the complexity of the operation and save the workload, improving the efficiency.
