DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1-Figure 9 The cable laying device for building electromechanical installation shown in the figure comprises a mobile frame 1, a column 2 is vertically arranged on the upper surface of the mobile frame 1, arms 6 are arranged on both sides of the outer surface of the column 2, and reinforcement components are arranged on the outside of two groups of arms 6, and U-shaped rods 7 are arranged inside the ends of the two groups of arms 6 away from the column 2, and wire racking shells 12 are arranged at the bottom of both ends of the two U-shaped rods 7, and routing components are arranged inside the two groups of wire racking shells 12, and buffer dragging components are arranged at the ends of the two groups of wire racking shells 12 on the same side away from each other;

[0031] The buffer cable assembly can buffer and support the cables extending at both ends in the cable clamping state and process the outer surface of the cable.

[0032] The reinforcement assembly includes a reinforcement rod 5 fixedly mounted on the lower outer side of the support arm 6, a fixing sleeve 3 is sleeved on the outer side of the column 2, and one end of the reinforcement rod 5 away from the support arm 6 is connected to the outer surface of the fixing sleeve 3;

[0033] With the connection of the reinforcement rod 5 , the support arm 6 can be more stably arranged outside the column 2 , so as to enhance the stability of the U-shaped rod 7 and the cable housing 12 during use.

[0034] The wiring assembly includes a card shaft 24 that is rotatably mounted inside the wire rack housing 12, a wheel 23 is sleeved on the outer side of the card shaft 24, a hollow groove is opened on the upper surface of the wire rack housing 12, a card housing 26 is slidably mounted inside the hollow groove, a card wheel 27 is rotatably mounted inside the card housing 26, a slide plate 29 is fixedly mounted on the outer wall of one side of the card housing 26, a U-shaped shell 25 is fixedly mounted on the upper surface of the wire rack housing 12, a screw rod 28 is rotatably mounted on the upper surface of the slide plate 29, one end of the screw rod 28 is threadedly penetrated through the upper surface of the U-shaped shell 25, and the slide plate 29 and the U-shaped shell 25 are slidably matched;

[0035] Under the connection of the clamping shaft 24, the wheel 23 can cooperate with the cable routing. When the cable is routed, it is convenient for workers to pull it to one end. The wheel 23 and the clamping shaft 24 cooperate with the cable to rotate, reducing the wear of the cable during routing.

[0036] When the worker drives the screw rod 28 to rotate, the slide plate 29 will be driven to move downward, and the card shell 26 will also drive the card wheel 27 to move downward, so that the card wheel 27 can move up and down inside the cable rack 12, so as to clamp different cables.

[0037] The buffer drag wire assembly includes a support frame 4 fixedly arranged on the outside of one end of the wire rack shell 12, and a support arm 15 is symmetrically arranged on the outside of the end of the support frame 4 away from the wire rack shell 12, and sliders 31 are slidably installed inside the two groups of support arms 15. A buffer shell 9 is commonly arranged on the side of the two groups of sliders 31 away from the support arm 15, and an arc-shaped plate 13 is fixedly arranged on the upper surface of the buffer shell 9, and the inside of the arc-shaped plate 13 is hollowed out, and an arc-shaped support plate 22 is symmetrically arranged inside the arc-shaped plate 13, and a sleeve seat 8 is arranged on the upper edge of the arc-shaped plate 13 and above the support plate 22, and a rolling contact assembly is arranged inside the buffer shell 9;

[0038] A U-shaped seat 36 is sleeved in the middle of the outer side of the buffer shell 9, and joints 30 are provided on both sides of the U-shaped seat 36. A sliding rod 17 is fixedly provided at the lower end of the joint 30, and a spring 16 is sleeved on the outside of the sliding rod 17. A fixed cylinder 10 is slidably sleeved on the outside and below the sliding rod 17. A support rod 14 is penetrated and connected inside the support frame 4 and located below the fixed cylinder 10, and the fixed cylinder 10 and the support rod 14 are fixedly connected;

[0039] The joint 30 is used to connect the U-shaped seat 36 and the sliding rod 17, so that the buffer shell 9 can drive the cable to vibrate up and down when it is affected by wind and snow, and the corresponding sliding rod 17 slides up and down inside the fixing tube 10 during the process, thereby dispersing the mechanical stress of the cable caused by external factors such as dead weight, wind load, ice and snow, and avoiding stress concentration that causes damage or breakage of the cable;

[0040] It should be emphasized that the upper end of the spring 16 is connected to the connector 30, and the lower end is connected to the upper surface of the fixed cylinder 10. Therefore, when the connector 30 moves, it will squeeze the spring 16 outside the sliding rod 17, so that the buffer shell 9 can elastically absorb shock, thereby avoiding the problem of excessive pulling of the cable.

[0041] The arc-shaped support plate 22 can ensure that the hollow portion can also fit with the surface of the cable when the buffer shell 9 is in use, thereby further improving the fit between the cable and the buffer shell 9.

[0042] The rolling contact assembly includes a rotating shaft 18, and the outer sides of both ends of the rotating shaft 18 are rotatably mounted with a clamping seat 19, the upper surfaces of the two clamping seats 19 are fixedly connected to the lower surfaces of the supporting plates 22 at corresponding positions, and the outer ends of the rotating shaft 18 are mounted with gears 20, and multiple groups of rolling elements are arranged on the outer side of the rotating shaft 18 and between the two groups of clamping seats 19;

[0043] When the sleeve 8 moves up and down in the buffer shell 9, it can limit the cable outside the extension to prevent the cable from falling off or shifting, reduce the safety risks such as electric shock and short circuit, and ensure the safety of personnel and equipment;

[0044] The holder 19 facilitates the rotation of the shaft 18 to be installed below the outside of the cable. When the shaft 18 rotates, multiple sets of rolling elements can come into contact with the outer surface of the cable, thereby achieving the purpose of later removal of objects and weight reduction.

[0045] The plurality of rolling elements include a disc 35 which is mounted on the outside of the rotating shaft 18 and located between the two sets of clamping seats 19. Clamping rods 32 are arranged at equal distances along the circumferential direction on the outer edge of the disc 35. Clamping rings 34 are mounted on both ends of the outer side of the clamping rods 32. The outer edge of the clamping rings 34 is provided with a plurality of irregular tooth grooves 33.

[0046] The disc 35 can be driven by the rotating shaft 18 to cause the clamping rod 32 and the external clamping ring 34 to rotate, and the corresponding irregular tooth grooves 33 break the ice and snow on the outer surface when contacting the cable, which can improve the maintenance efficiency during daily maintenance of the cable stringing device.

[0047] A U-shaped frame 11 is fixedly mounted inside one of the support arms 15. Multiple sets of tooth blocks 21 are arranged on the outer surfaces of both ends of the U-shaped frame 11 at equal vertical distances, and the multiple sets of tooth blocks 21 are meshed with the corresponding gears 20.

[0048] Multiple groups of gear blocks 21 are installed at equal distances on the outer surface of the U-shaped frame 11, so that a rack is formed at both ends of the U-shaped frame 11. When the buffer shell 9 moves up and down, the corresponding gear 20 is meshed with the rack, so that the components outside the rotating shaft 18 can be rotated for use.

[0049] Working principle: When in use, the cables to be installed are sequentially inserted into the two groups of wiring shells 12 on the same side, and the screw 28 is rotated according to the diameter of the cable, thereby driving the slide plate 29 and the clamping wheel 27 to move down to the outside and above the cable to install the cable. During use, if the cable is loaded at both ends due to external reasons, the corresponding buffer shell 9 slides downward through the sliders 31 on both sides of the outside to squeeze the spring 16 outside the sliding rod 17, so that the buffer shell 9 can reduce the load, thereby improving the downward pressure angle on both sides, avoiding the problem of unstable wiring device tipping over due to cable pulling. In addition, the cable is installed inside the buffer shell 9, and the cable is also supported for a long distance at both ends of the installation device. The support can effectively disperse the mechanical stress of the cable caused by external factors such as its own weight, wind load, ice and snow, and avoid stress concentration that causes cable damage or breakage. At the same time, with the installation of the buffer shell 9, the line support distance is extended, and the bending radius of the cable is limited to prevent excessive bending, thereby protecting the internal conductor and insulation layer and extending the life of the cable. When the cable surface is covered with ice and snow, the device can press and lift the buffer shell 9 so that the rotating shaft 18 inside the buffer shell 9 engages with the multiple groups of tooth blocks 21 on the outer surface of the U-shaped frame 11 on one side, thereby prompting the rotating shaft 18 to drive the multiple groups of external disks 35 to rotate. The rotation of the disk 35 prompts the multiple clamping rods 32 and the clamping rings 34 on the outer edge to roll in contact with the outer surface of the cable. As a result, the multiple groups of irregular tooth grooves 33 outside the clamping rod 32 roll against the ice and snow on the outer surface of the cable, and the ice layer is broken through the friction resistance, so that the wired cable can be reduced in weight, thereby ensuring the stability of the erection device, avoiding the problem of the device tipping over, and ensuring the safety of the wire.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
