Description

Technical Field

[0001] The utility model relates to the technical field of wire taking-up devices, in particular to a serpentine wire taking-up device and a lifting device. Background Art

[0002] During the lifting process of the lifting mast, the cables of the electrical equipment on the top (antenna equipment, electromechanical equipment, etc.) need to be lifted and lowered. At present, the main methods of retracting and releasing cables in the industry are manual retracting and releasing, retracting and releasing cables with a reel, and retracting and releasing cables with a spring cable. These three retracting and releasing methods have the following problems:

[0003] First, manual retracting and releasing lines require specialized personnel to perform retracting and releasing, and cannot be automated, so they are gradually being eliminated;

[0004] Second, there are two types of take-up wheels: one with an electric slip ring and one without an electric slip ring. The cost of a take-up wheel with an electric slip ring is relatively high. Usually, one electric slip ring costs several thousand yuan. When the transmission signal is an RF signal or an optical signal, the electric slip ring used costs tens of thousands or even hundreds of thousands of yuan. In addition, the signal in the cable will be attenuated when passing through the electric slip ring, which reduces the signal transmission efficiency. For a take-up wheel without an electric slip ring, when the lifting rod is working, the take-up wheel rotates. In order to avoid cable entanglement, the cable on the wheel and the cable on the ground need to be manually disconnected, and the connector is manually plugged in and out, which cannot be automated, and the setting of the connector will cause signal loss.

[0005] Third, the spring cable is a cable that binds one or more springs and cables together, and relies on the automatic contraction of the spring to complete the winding. When the spring cable is installed, it needs to be coaxial with the lifting rod tube assembly, with one end fixed to the top of the lifting rod and the other end fixed to the bottom of the spring cable frame. When the lifting rod rises, its top drives the spring cable to unfold. When the lifting rod descends, the spring itself relies on its own contraction force to achieve winding. 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 spring cables usually increase the spring diameter or the number of turns, resulting in the need for a longer cable. The required cable length is generally more than twice the lifting stroke.

[0006] In view of this, a serpentine wire taking-up device is urgently needed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0058] See also Figure 1-15 , the embodiments of the utility model are further described;

[0059] A serpentine wire taking-up device, comprising:

[0060] Telescopic guide device 1;

[0061] A cable assembly 3, wherein the cable assembly 3 is at least one and arranged in a serpentine shape, and the cable assembly 3 is located above the telescopic guide device 1;

[0062] Positioning components, a plurality of positioning components are provided and all are installed outside the cable assembly 3;

[0063] The number of traction components is equal to the number of cable components 3 , and the upper end of the traction component passes through a plurality of positioning components, and the lower end is wound in the telescopic guide device 1 .

[0064] In this embodiment, Figure 1 As shown, the serpentine wire-winding device is used in conjunction with a lifting rod, the telescopic guide device 1 and the lifting rod are both fixed on a fixed seat, a mounting plate is fixed to the upper end of the lifting rod, and an electrical device is fixed on the mounting plate, the upper end of the traction assembly is fixed to the mounting plate, the upper end of the cable assembly 3 is electrically connected to the electrical device, and the lower end of the cable assembly 3 is fixedly connected to the fixed seat; wherein, the mounting plate is marked as 6 in the figure, the electrical device is marked as 7 in the figure, the lifting rod is marked as 8 in the figure, and the fixed seat is marked as 9 in the figure.

[0065] The working principle of the serpentine take-up device is as follows:

[0066] When the lifting rod 8 rises, it will drive the electrical equipment 7 to move upward. During this process, the traction assembly on the telescopic guide device 1 is pulled out synchronously, and the electrical equipment 7 pulls the cable assembly 3 upward. The positioning assembly slides upward on the traction assembly under the traction of the cable assembly 3. Several positioning assemblies can position multiple parts of the cable assembly 3; when the lifting rod 8 reaches the maximum stroke, that is, when the electrical equipment 7 rises to the highest point, the cable assembly 3 is close to a straightened state. It should be noted that the length of the cable assembly 3 is less than 1.1 times the stroke of the lifting rod 8, which greatly shortens the length of the cable required for the equipment at the top of the lifting rod, thereby improving the signal transmission efficiency and reducing costs, and realizing automatic release of the cable assembly 3 when the lifting rod 8 rises.

[0067] When the lifting rod 8 descends, the traction assembly is synchronously retracted under the action of the telescopic guide device 1, and at the same time, the positioning assembly slides downward on the traction assembly under its own gravity and the gravity of the cable assembly 3; when the lifting rod 8 is closed, the cable returns to its initial state, realizing automatic storage of the cable assembly 3 when the lifting rod 8 descends.

[0068] The cable assembly 3 can be arranged symmetrically on both sides or on one side; when the cable assembly 3 is single or in order to save costs, the cable can also be arranged on one side, such as Figure 13-15 shown.

[0069] The cable assembly 3 is designed to be arranged in a serpentine shape so that the cable assembly 3 can be neatly contracted under the action of external force.

[0070] Compared with the take-up wheel with slip ring, the serpentine take-up device does not need to use electric slip ring, which greatly reduces the use cost, and the signal in the cable assembly 3 will not be attenuated, ensuring the signal transmission efficiency;

[0071] Compared with the take-up wheel without slip ring, the serpentine take-up device is more automated, eliminating the need for manual plugging, and the utility model reduces the use of connectors, so the signal transmission efficiency in the cable assembly 3 is higher;

[0072] Compared with the spring cable, the serpentine take-up device of the utility model can significantly shorten the length of the cable assembly 3 required for the electrical equipment 7, thereby improving the signal transmission efficiency and reducing the cost.

[0073] The telescopic guide device 1 comprises:

[0074] Bracket 11;

[0075] A spring box 12, the spring box 12 is installed on one side of the bracket 11;

[0076] A rotating shaft 13, the rotating shaft 13 is rotatably connected to the bracket 11, and one end of the rotating shaft 13 extends into the spring box 12 and contacts therewith;

[0077] The reel 14 is sleeved and fixed on the rotating shaft 13 , and the lower end of the traction component is wound on the reel 14 .

[0078] In this embodiment, the bracket 11 is used to support the spring box 12, the rotating shaft 13 and the winding drum 14. The spring box 12 is provided with a spiral spring, and the rotating shaft 13 is detachably connected to the spiral spring (such as plug-in or clip-on);

[0079] When the lifting rod 8 rises, the traction assembly on the drum 14 is pulled out and drives the drum 14 to rotate, and the drum 14 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the scroll spring in the spring box 12 to store energy; when the lifting rod 8 descends, the scroll spring in the spring box 12 drives the drum 14 to rotate and retract the traction assembly, thereby realizing the automatic retraction and release of the traction assembly.

[0080] The cable assembly 3 includes:

[0081] Cable 31, cable 31 is provided with a plurality of;

[0082] The protective cover 32 has a row of holes therein for accommodating a plurality of cables 31 .

[0083] In this embodiment, the protective cover 32 is used to protect a plurality of cables 31. After being inserted into the protective cover 32, the plurality of cables 31 are arranged in a row. This design can effectively reduce the bending radius of the cables 31. Cables 31 arranged in other ways can still be applied to the present invention.

[0084] The positioning components include:

[0085] A plurality of cable clamps 5 are provided and are evenly clamped on the cable assembly 3;

[0086] The guide rotating device 4 is provided with a plurality of cable clamps 5 which are detachably connected to the cable clamps 5 , and the upper end of the traction assembly passes through the plurality of guide rotating devices 4 .

[0087] In this embodiment, the cable clamp 5 is used to clamp the cable. Since the cable clamp 5 is detachably connected to the guide rotating device 4, and the guide rotating device 4 is inserted into the traction component, the cable component 3 can be positioned in a serpentine shape on the traction component; when the lifting rod 8 is lifted or lowered, it will drive the cable component 3 to expand or contract. During this process, the cable component 3 will drive the cable clamp 5 to rotate on the guide rotating device 4 to realize automatic release or retraction of the cable component 3.

[0088] The guide rotation device 4 comprises:

[0089] Guide plate 41;

[0090] A mounting rod 42, the mounting rod 42 is laterally inserted and fixed on the guide plate 41;

[0095] When the cable assembly 3 is expanded or contracted, the cable clamp 5 will be driven to rotate on the guide rotating device 4, and the torsion spring 45 will also be stretched or compressed. If the lifting rod 8 descends, the torsion spring 45 with elastic potential energy will drive the rotating plate 44 to rotate, and the rotating plate 44 will drive the cable clamp 5 and the cable assembly 3 to rotate, so that the cable assembly 3 returns to its original position.

[0096] The limiter components include:

[0097] A limiting column 43, at least one limiting column 43 is provided and fixed on the guide plate 41;

[0098] A limiting groove 46 is formed on the rotating plate 44 , and the end of the limiting post 43 extends into the limiting groove 46 .

[0099] In this embodiment, the limiting column 43 and the limiting groove 46 are structures for limiting the guide plate 41 and the rotating plate 44 to each other, so as to limit the rotating plate 44 and the torsion spring 45 .

[0100] The limiting groove 46 is in an arc shape of 90°.

[0102] The traction assembly includes a steel wire rope 2, which has high hardness and strong tensile strength, and is conducive to extending the service life of the traction assembly.

[0103] The utility model also provides a lifting device, including the above-mentioned serpentine wire taking-up device, a mounting plate 6, a lifting rod 8 and a fixed seat 9, the telescopic guide device 1 and the lifting rod 8 are fixed on the fixed seat 9, the mounting plate 6 is fixed to the upper end of the lifting rod 8, and an electrical device 7 is fixed on the mounting plate 6, the upper end of the traction assembly is fixed on the mounting plate 6, the upper end of the cable assembly 3 is electrically connected to the electrical device 7, and the lower end of the cable assembly 3 is fixedly connected to the fixed seat 9.

[0104] In this embodiment, the working principle can refer to the above embodiment and will not be described in detail. The lifting device can significantly shorten the length of the cable assembly required for the electrical equipment, reduce the use of connectors and eliminate the need for electric slip rings, improve the signal transmission efficiency in the cable assembly and reduce the cost, and the serpentine take-up device can automatically take up and release the wire.

[0105] The following are examples:

[0106] The working stroke of the lifting rod 8 is 12m, and the cables 31 are two HCAAYZ-50-12 radio frequency coaxial cables with an attenuation of 4.75dB / 100m and a price of about 15 yuan / m. It is required that the attenuation on the cable 31 shall not be greater than 1dB.

[0107] If spring cables are used, the required length of each cable is 25m, the attenuation is 1.19dB, and the price is 375 yuan. If the utility model is used, the required length of each cable is 12.5m, the attenuation is 0.59dB, and the price is 187.5 yuan.

[0108] If a take-up wheel with a slip ring is used, the price of the slip ring is about 8,000 yuan, and considering the cost of the take-up wheel itself is 4,000 yuan, the total cost is about 12,000 yuan. If the present invention is used, the total cost is about 4,000 yuan, which is lower. When a take-up wheel with a slip ring is used, the total length of the cable 31 is close to that of the present invention, and the signal in the cable 31 is attenuated when passing through the slip ring, which is about 0.6dB more attenuated than the present invention, and the signal transmission efficiency is lower than that of the present invention.

[0109] The comparison shows that the utility model can not only meet the specified signal attenuation requirements, but also has better economic benefits.
