Description

Technical Field

[0001] The utility model relates to the technical field of cable retracting and releasing, and more specifically, to a spiral cable retracting device. Background Art

[0002] When the lifting rod is being raised or lowered, the cables connected to the equipment on top of it need to be raised or lowered along with it. Currently, the main methods for retracting and paying out cables in the industry include manual retracting and paying out and retracting and paying out with a reel.

[0003] Among them, manual wire reeling and unwinding requires specialized personnel to perform the work, cannot be automated, and is gradually being eliminated; wire reeling wheels are divided into two types: those with powered slip rings and those without powered slip rings: those with powered slip rings are more expensive, typically costing several thousand yuan, and when the transmission signal is a radio frequency signal or an optical signal, the price of the slip ring is tens of thousands or even hundreds of thousands of yuan; for those without powered slip rings, when the lifting rod is working, the wire reel rotates, and in order to prevent the cable from being entangled, the cable on the reel needs to be manually disconnected from the cable on the ground, and the connector needs to be manually plugged in and out, which cannot be automated.

[0004] As a result, spring cable retractable cables gradually emerged. Spring cables are cables that bind one or more springs and cables together, and rely on the automatic contraction of the springs to complete the retraction. However, when the spring cable is stretched, its radial dimension will become smaller. In order to avoid interference with the lifting rod tube assembly during stretching, the existing common spring cables usually increase the spring diameter or increase the number of turns, resulting in the need for a longer cable (the required cable length is generally more than twice the lifting stroke, such as Figure 5 and Figure 6 At the same time, in order to avoid permanent deformation during operation and affect the wire collection, the spring cross-section diameter of ordinary spring cables is larger, which consumes more materials and reduces economic benefits. Utility Model Content

[0005] The utility model aims to provide a spiral cable take-up device, which solves the problem in the prior art of wasting materials and reducing economic benefits due to high requirements on cable length and spring cross-section diameter.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a spiral cable take-up device, including a lifting rod, whose bottom is fixed on the ground, and a device is installed on the top telescopic end of the lifting rod; a cable frame, which is fixed on the ground on one side of the lifting rod, and a cable is connected between the cable frame and the device; a winding assembly, which is arranged on the surface of the cable, and the winding assembly is used to automatically wind the cable into the cable frame when the lifting rod is lowered.

[0007] The working principle of this technical solution is as follows: when in use, when the lifting rod is controlled to drive the equipment to rise, the cable connected to the equipment will be stretched from the cable frame located on one side of the lifting rod. When the lifting rod is lowered, under the action of the winding assembly, the cable will automatically be wound up and stored in the cable frame, which is convenient for the next lifting work.

[0008] In summary, the utility model has the following beneficial effects:

[0009] Compared with the prior art, the utility model provides a spiral cable winding device by setting a cable frame on one side of the lifting rod, and setting a cable in the cable frame to connect with the equipment, and using a winding assembly to realize automatic winding of the cable when the lifting rod is lowered. When the lifting rod rises and works, its top extends upward under the action of external force, away from the bottom of the lifting rod, and at the same time drives the cable and the winding assembly to unfold. Under the action of the top of the lifting rod and its own gravity, the axial length of the cable becomes longer and the radial size becomes smaller until it is fully unfolded. Compared with the prior art, the requirements for the length of the cable or the diameter of the spring are smaller at this time, which saves materials and improves economic benefits.

[0010] Furthermore, the winding assembly includes a spiral steel wire and a plurality of cable ties, wherein the plurality of cable ties bind and fix the cable wire to the spiral steel wire.

[0011] Furthermore, it also includes a cable arrangement assembly, which includes a support base fixed on the ground, the cable frame is fixedly set on the support base, the outer rotating sleeve of the support base is provided with a mounting sleeve, and an "L-shaped" cable arrangement rod is fixedly connected to the mounting sleeve. The free end of the cable arrangement rod extends to the top of the cable frame and is connected to a winding coil for the cable to pass through, wherein a vortex spring that cooperates with the mounting sleeve is installed inside the support base.

[0012] Furthermore, a support rod for supporting the cable is installed at the telescopic end of the lifting rod.

[0013] Furthermore, a mounting column is fixedly arranged on the support seat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 —4 The utility model is further described in detail.

[0022] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a spiral cable winding device, including a lifting rod 1, whose bottom is fixed on the ground, and a device 2 is installed on the top telescopic end of the lifting rod 1; a cable frame 5, which is fixed on the ground on one side of the lifting rod 1, and a cable 4 is connected between the cable frame 5 and the device 2; a winding component, which is arranged on the surface of the cable 4, and the winding component is used to automatically wind the cable 4 into the cable frame 5 when the lifting rod 1 descends.

[0023] The specific working process is: when the lifting rod 1 is controlled to drive the device 2 to rise, the cable 4 connected to the device 2 will be stretched from the cable frame 5 located on one side of the lifting rod 1, and when the lifting rod 1 descends, under the action of the winding component, the cable 4 will be automatically wound up and stored in the cable frame 5, which is convenient for the next lifting work.

[0024] In this embodiment, a cable frame 5 is provided on one side of the lifting rod 1, and a cable 4 is provided in the cable frame 5 to connect with the device 2, and a reeling assembly is used to realize automatic reeling of the cable 4 when the lifting rod 1 is lowered. When the lifting rod 1 is raised, its top is extended upward under the action of external force, away from the bottom of the lifting rod 1, and at the same time, the cable 4 and the reeling assembly are driven to unfold. Under the action of the top of the lifting rod 1 and its own gravity, the axial length of the cable 4 becomes longer and the radial dimension becomes smaller until it is fully unfolded. Compared with the prior art, the length of the cable 4 or the diameter of the spring is less required at this time, which saves materials and improves economic benefits.

[0025] In actual use, in order to improve the overall stability of the device after the cable 4 is stretched, a support rod 3 for supporting the cable 4 may be installed at the telescopic end of the lifting rod 1 .

[0026] like Figure 1 and Figure 3 As shown, according to another embodiment of the utility model, a spiral cable winding device is provided, wherein the winding assembly comprises a spiral steel wire 6 and a plurality of cable ties 7 , wherein the cable 4 and the spiral steel wire 6 are bundled and fixed by the plurality of cable ties 7 .

[0027] This scheme is to achieve the bundling and fixing of the cable line 4 by setting a spiral steel wire 6 and a plurality of cable ties 7 to cooperate with each other. When the lifting rod 1 rises and works, its top extends upward under the action of external force, away from the bottom of the lifting rod 1, and at the same time drives the cable line 4 and the spiral steel wire 6 to unfold. The cable line 4 is at the top of the lifting rod 1 and under the action of its own gravity. The axial length of the cable line 4 becomes longer and the radial size becomes smaller until it is fully unfolded. Since the cross-sectional diameter of the spiral steel wire 6 is small, it is almost "straightened" under the action of the spiral cable 6's own gravity. Therefore, after it is fully unfolded, the radial diameter of the spiral cable is extremely small, which effectively utilizes the radial space. Compared with ordinary spring cables, the length of the required cable is greatly shortened. At the same time, since the small spiral steel wire 6 has a small elastic force, and the required length of the cable line 4 is shorter and the gravity is smaller, the pulling force on the top of the lifting rod 1 is smaller than that of the spring cable. When the lifting rod 1 descends, its top is retracted downward under the action of external force and gradually approaches the bottom of the lifting rod 1. At the same time, the spiral cable is shortened in axial direction and enlarged in radial direction under the action of the top of the lifting rod 1, its own gravity and the elastic force of the spiral steel wire 6, and is curled in the cable frame 5 to achieve automatic retraction.

[0028] like Figure 4 As shown, according to another embodiment of the utility model, a spiral cable take-up device also includes a wire arrangement assembly, wherein the wire arrangement assembly includes a support seat 10 fixed on the ground, the cable frame 5 is fixedly arranged on the support seat 10, and the outer rotating sleeve of the support seat 10 is provided with a mounting sleeve 11, and an "L-shaped" wire arrangement rod 14 is fixedly connected to the mounting sleeve 11, and the free end of the wire arrangement rod 14 extends to the top of the cable frame 5 and is connected to a winding coil 15 for the cable 4 to pass through, wherein a vortex spring 9 that cooperates with the mounting sleeve 11 is installed inside the support seat 10.

[0029] The present scheme realizes the cable arrangement and wiring when the cable 4 is retracted by setting a support seat 10, an installation sleeve 11, a vortex spring 9, a wiring coil 15 and a wire arrangement rod 14 to cooperate with each other. During use, when the cable 4 and the spiral steel wire 6 are unfolded, the wire arrangement rod 14 and the installation sleeve 11 will rotate in the unfolding direction of the spiral steel wire 6 driven by the wiring coil 15. When retracting, the wire arrangement rod 14 and the installation sleeve 11 will rotate in the retracting direction of the spiral steel wire 6. The installation sleeve 11 is pre-tightened by the vortex spring 9 and can rotate relative to the support seat 10 and the cable frame 5. When the cable 4 is unfolded, the installation sleeve 11 rotates to pre-tighten the vortex spring 9. When retracting, the spiral steel wire 6 and the cable 4 are folded back into the cable frame 5 under the action of the vortex spring 9.

[0030] In actual use, in order to better assist in cable management, a mounting column 8 may be fixedly provided on the support base 10 .

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
