Description

Technical Field

[0001] The invention relates to the technical field of cable transportation, in particular to a high-rise building cable transportation device. Background Art

[0002] Existing cable conveying devices usually adopt a clamping conveyor belt structure, which is mainly composed of a conveying crawler, a drive motor, a support base and a clamping mechanism. The working principle of the traditional cable conveying device is to continuously pull and convey the cable through the friction of the conveying crawler. The drive motor serves as the main power source to drive the crawler to move, thereby realizing the linear transportation of the cable. This structure is relatively simple and low-cost, and is suitable for cable laying needs in some scenarios. However, traditional cable conveying devices expose a series of technical defects when facing complex and high-rise building environments.

[0003] Discontinuous cable conveying: The existing conveying crawler mechanism mainly relies on friction to convey cables. Crawler conveying only relies on the linear friction of surface contact and lacks precise clamping control of the cable. When the cable is bent or irregularly shaped, the conveying will be significantly affected, and even cause cable damage or interruption of conveying.

[0004] Poor adaptability: Traditional clamping mechanisms are usually fixed structures that cannot flexibly adapt to the transmission needs of cables of different specifications and diameters. This lack of flexibility in design requires repeated adjustments or replacement of components in actual use, resulting in low efficiency and difficulty in adapting to diverse transmission needs.

[0005] High-rise environments are difficult to operate and have low safety: Traditional conveying devices are mostly designed for ground operation and lack the function of fixing and stabilizing the walls of high-rise buildings. In high-rise environments, cable conveying devices cannot be reliably positioned and require additional fixed brackets or manual assistance, which not only increases the difficulty of operation, but also increases the safety risks of high-altitude operations.

[0006] In view of this, research and improvement are carried out on the existing problems, and a high-rise building cable conveying device is provided to solve the current problems. The purpose is to solve the problems and improve the practical value through this technology. Summary of the invention

[0007] The present invention aims to solve technical problems existing in the prior art or related technology, such as discontinuous transportation, poor adaptability, insufficient safety and easy damage of cable surface of existing cable conveying devices in high-rise building applications. To this end, the present invention proposes a new type of high-rise building cable conveying device, which realizes efficient, safe and continuous transportation of cables through innovative peristaltic conveying structure and modular design, and is adaptable to a variety of building environments and cable specifications.

[0008] To this end, the technical solution adopted in the present invention is: A high-rise building cable conveying device comprises a crawling seat, a cable guiding mechanism, a cable conveying mechanism and a hydraulic drive assembly fixed inside the crawling seat, wherein the surface of the crawling seat is provided with a lifting lug, a winch assembly and a positioning suction cup, the cable guiding mechanism comprises a fixed seat, a chuck arc and a plurality of adjustment rod groups distributed on the surfaces of the fixed seat and the chuck arc, the adjustment rod group is used to drive the radial movement of the chuck arc and the fixed seat to meet the conveying requirements of cables of different specifications; the cable conveying mechanism comprises a shaft rod, a hydraulic drive assembly, a motion set and a series pipe set, and the hydraulic drive assembly drives the shaft rod to rotate so that the motion set can realize radial clamping and pushing actions to complete the creeping conveying of the cable.

[0009] In a preferred example, the present invention can be further configured as follows: Modular design of lifting function: The winch assembly includes an electric winch and a steel cable reel, which can cooperate with the external cable through the lifting lug to realize the lifting movement of the crawling seat on the wall of a high-rise building. At the same time, the negative pressure adsorption function of the positioning suction cup can firmly fix the crawling seat on the wall to ensure the safe operation of the device.

[0010] Optimization of peristaltic conveying continuity: The shaft adopts an eccentric sleeve design. Through the cooperation of the eccentric sleeve and the rotary slide groove, the motion set can achieve reciprocating motion in the radial direction. Combined with the function of the sliding ball and the cable stop, it ensures the automatic alternation of cable clamping and pushing, avoids cable slippage or conveying interruption, thereby improving the continuity and smoothness of the conveying process.

[0011] Adaptation to cables of various specifications: The chuck arc and the adjusting rod group in the cable guide mechanism realize radial adjustment in the form of arc combination, which can adapt to cables of different diameters and specifications. It can be flexibly adjusted without replacing parts, thus improving the adaptability and working efficiency of the equipment.

[0012] Hydraulic drive with efficient transmission: The hydraulic drive assembly is connected to the hydraulic pump assembly through a series pipe assembly. The synchronous operation of the hydraulic drive assembly can realize multi-point drive of the shaft rod, and the meshing design of the hydraulic gear and the shaft rod ensures efficient transmission and stable operation of the conveying mechanism power.

[0013] Cable protection function: The cable retainer in the sports set adopts an arc-shaped anti-slip edge design with a high friction coefficient, which can not only enhance the clamping force, but also reduce the wear on the cable surface, effectively extending the service life of the cable. It is particularly suitable for the transportation of special cables or optical fiber cables.

[0014] Adaptability to high-rise buildings: The device adopts a modular design as a whole. The crawling seat, cable guide mechanism and cable conveying mechanism can be quickly assembled and disassembled, which is suitable for the cable laying and maintenance needs of high-rise buildings of different heights and complex environments.

[0015] Through the above technical scheme, the present invention overcomes many shortcomings in the existing cable transmission technology, has significant advantages such as strong transmission continuity, wide adaptability, high safety, and good cable protection, and can be widely used in the laying and maintenance of cables in high-rise buildings.

[0016] The beneficial effects achieved by the present invention are: 1. In the present invention, the cable conveying mechanism realizes the automatic alternating action of clamping and disengaging the cable during the conveying process through the synchronous operation of the hydraulic drive assembly and the design of the eccentric sleeve, combined with the guiding effect of the rotary slide groove and the slide ball, to realize peristaltic conveying. The peristaltic conveying structure is driven by the movement of the eccentric shaft, so that the clamping assembly alternately clamps and pushes in the radial direction. Peristaltic conveying can adapt to the irregularity of the cable surface shape, and ensure that the cable always maintains precise clamping and continuous conveying, which is particularly suitable for high-strength and high-load cable conveying scenarios.

[0017] 2. In the present invention, the cable guiding mechanism can flexibly adapt to the transmission requirements of cables of different diameters and specifications through the arc combination design of the clamping head arc and the adjusting rod group; at the same time, the device structure adopts a modular design, the various components are highly coordinated, and maintenance and expansion are convenient, and it can be widely used in the laying and maintenance of cables in high-rise buildings.

[0018] 3. In the present invention, the combined design of the crawling seat and the positioning suction cup realizes the stable positioning of the device on the wall of a high-rise building, and the lifting and lowering movement of the device is completed by the winch assembly, which effectively reduces the safety risks of manual operation and improves the efficiency of high-altitude operations.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A high-rise building cable conveying device provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] Combination Figure 1-Figure 7 As shown, the present invention provides a high-rise building cable conveying device, comprising a crawling seat 100, a cable guide mechanism 200, a cable conveying mechanism 300 and an internal hydraulic drive assembly. The device is designed for stable and continuous conveying of cables in high-rise buildings.

[0025] 1. Design of crawler seat 100: The crawling seat 100 is a supporting structure of the device, and a lifting lug 110, a winch assembly 120 and a positioning suction cup 130 are arranged on the surface of the crawling seat 100.

[0026] The winch assembly 120 includes an electric winch and a cable reel, and is used to achieve the lifting and lowering movement of the crawling seat 100 along the wall of a high-rise building through a suspension cable.

[0027] The positioning suction cup 130 generates negative pressure adsorption force through a built-in vacuum generator, which can firmly fix the crawling seat 100 on the wall, thereby ensuring the stability and safety of the device during high-altitude operations.

[0028] 2. Design of cable guide mechanism 200: The cable guiding mechanism 200 includes a fixing seat 210 , a clamping arc 220 and a plurality of adjusting rod groups 230 .

[0029] The fixing seat 210 and the chuck arc 220 are in an arc shape and are combined to form a circular ring structure. The adjustment rod group 230 is evenly distributed along the circumferential direction of the fixing seat 210 and the chuck arc 220 .

[0030] The adjusting rod group 230 can realize radial expansion and contraction, and is used to adjust the clamping radius of the clamping arc 220 and the fixing seat 210 to meet the requirements of cables of different diameters and specifications. The clamping arc 220 is connected to the fixing seat 210 through a fastener 221 to ensure the stability of clamping.

[0031] 3. Design of the cable conveying mechanism 300: The cable conveying mechanism 300 includes a shaft 310 , a hydraulic drive assembly 320 , a motion set 330 , and a series pipe set 340 .

[0032] The hydraulic drive assembly 320 is connected to the hydraulic pump assembly through the series pipe assembly 340. The hydraulic pump provides power to the hydraulic drive assembly 320 to drive the shaft 310 to rotate eccentrically.

[0033] The surface of the shaft 310 is sleeved with an eccentric sleeve 311, and a plurality of rotary grooves 312 are formed on the eccentric sleeve 311. The motion set 330 is slidably mounted on the surface of the shaft 310, and a plurality of sliding balls 332 are provided inside the motion set 330, which slide in cooperation with the rotary grooves 312, so that the motion set 330 can reciprocate in the radial direction.

[0034] A cable stop bar 331 is provided on one side of the sports set 330 . The surface of the cable stop bar 331 is provided with anti-skid edges for contacting with the surface of the cable to prevent the cable from sliding and improve the transmission efficiency.

[0035] 4. Conveying principle and characteristics of peristaltic structure: The cable conveying drives the shaft 310 to rotate through the hydraulic drive assembly 320, and the eccentric design of the eccentric sleeve 311 enables the motion set 330 to perform radial reciprocating motion.

[0036] Under the clamping action of the cable stop bar 331, the motion set 330 realizes the clamping and pushing of the cable. The rotary slide groove 312 on the eccentric sleeve 311 guides the sliding ball 332, and cooperates with the eccentric rotation action to enable the motion set 330 to complete the alternating actions of clamping and pushing and disengaging and returning, thereby realizing continuous transportation of the cable.

[0037] The multiple hydraulic drive assemblies 320 are connected via the series pipe group 340 and work synchronously to ensure the overall coordination of the conveying mechanism.

[0038] 5. Modular design and high-level adaptability: The device of the present invention adopts a modular design, and the crawling seat 100, the cable guiding mechanism 200 and the cable conveying mechanism 300 can be quickly assembled and disassembled, so that it is convenient for flexible application in different environments of high-rise buildings.

[0039] The negative pressure adsorption function of the positioning suction cup 130 further enhances the stability of the device in the high-rise wall environment. Combined with the lifting function of the winch assembly 120, the device can easily cope with construction requirements of different heights and complex terrains.

[0040] Application scenarios in the embodiments Example 1: Ordinary cable laying In a scenario where ordinary cables need to be laid, the cable guide mechanism 200 is used to adjust the clamping radius to adapt to the cable diameter; after the cable conveying mechanism 300 is started, the clamping assembly conveys the cable from the ground to the top of the building with a uniform creeping motion, and the process is smooth and efficient.

[0041] Example 2: Laying of special cables such as optical fibers For special cables such as optical fibers, the arc-shaped anti-skid edge design of the cable stop 331 effectively reduces the wear on the cable surface, and the high-strength material of the sliding ball 332 further reduces the friction, ensuring the safety and integrity of the cable.

[0042] The working principle and use process of the present invention: A high-rise building cable conveying device of the present invention realizes stable clamping and continuous conveying of cables and efficient operation in a high-rise building environment through the coordinated work of a crawling seat, a cable guiding mechanism and a cable conveying mechanism.

[0043] 1. Positioning and fixing principle: The crawling seat 100 is the main structure of the device, and realizes negative pressure adsorption on the wall of the high-rise building through the positioning suction cup 130, forming a stable fixing effect. The vacuum generator generates negative pressure in the suction cup, which firmly adsorbs the crawling seat to the wall to prevent position deviation or sliding during operation.

[0044] The winch assembly 120 is driven by an electric winch, which drives the crawler seat to move up and down on the wall through a suspension cable, so that the device can flexibly adjust the working height to meet the cable transportation needs of different storey heights.

[0045] Specifically, in different working modes of the cable conveying device, the lifting and lowering movement of the crawling seat 100 can be achieved by using the winch assembly 120 fixed on it, or by connecting the cable of the lifting equipment fixed on the top of the high-rise building with the lifting ear 110; further, in the cable conveying work, the crawling seat 100 can be adsorbed and fixed to the wall by the positioning suction cup 130 to position the cable for cable conveying.

[0046] 2. Cable guide and adaptation principle: The fixing seat 210 and the clamping arc 220 of the cable guide mechanism 200 can adapt and clamp cables of different diameters and specifications by adjusting the radial expansion and contraction of the rod group 230. The arc structure of the clamping arc ensures stable guidance of the cable during transportation and avoids bending or dislocation of the cable.

[0047] 3. Cable creeping conveying principle: The cable conveying mechanism 300 controls the rotation of the shaft 310 through the hydraulic drive assembly 320 , and the eccentric sleeve 311 on the surface of the shaft drives the motion set 330 to achieve radial reciprocating motion during the rotation process.

[0048] A cable stop bar 331 is provided on one side of the motion set 330, which contacts the surface of the cable and continuously transports the cable upward through clamping and pushing actions; the rotary slide groove 312 of the eccentric sleeve 311 cooperates with the slide ball 332 to enable the motion set to achieve alternating actions of clamping, pushing and disengaging and returning in the radial direction, thereby realizing continuous transportation of the cable.

[0049] Specifically, under the eccentric effect of the eccentric sleeve 311, the shaft 310 and the eccentric sleeve 311 rotate to drive the moving set 330 to reciprocate in the radial direction, and reciprocately abut against the surface of the cable; under the guiding effect of the rotary slide groove 312, as the shaft 310 rotates, the sliding ball 332 and the rotary slide groove 312 make the moving set 330 reciprocate on the axis of the shaft 310 to transport the cable; and then through the combined effect of the two movements, the clamping and pushing of the cable in the process movement and the disengagement and return movement are realized, and the continuous transportation of the cable is realized under the alternating action of the two movements.

[0050] The series pipe group 340 connects the hydraulic drive components 320 to ensure the synchronous operation of the drive components, so that the multiple motion sets can operate in a coordinated manner, further improving the transmission efficiency and stability.

[0051] Specifically, the synchronous rotation of the shaft 310 is achieved under the synchronous operation of the hydraulic drive assembly 320, and the alternating operation of each movement set 330 is achieved under the different eccentric effects of the eccentric sleeve 311, and each movement set 330 transports the cable alternately and continuously.
