Description

Technical Field

[0001] This utility model belongs to the field of power construction equipment, and specifically relates to a cable reel laying frame for power construction. Background Technology

[0002] After production, cables are wound onto cable reels. Due to the large size and weight of the cable reels, during power construction, a cable laying frame is used to elevate the reels off the ground and allow them to rotate and lay the cable. A common cable laying frame consists of a support roller and two side frames. The two ends of the support roller are each mounted on a side frame, and the cable reel is mounted on the support roller. By installing a lifting mechanism on the two side frames and driving the support roller upwards through the lifting mechanism, the cable reel can be lifted off the ground, enabling the cable laying operation.

[0003] Compared to gantry-type cable trays, the above-mentioned cable trays have the advantages of convenient transportation, small storage space, light weight, and easy placement. However, since its two side frames are independent and the lifting mechanism requires manual operation, the two side frames may have inconsistent adjustment amounts when adjusting the lifting mechanism, causing the support rollers to tilt. Since the cable reel is heavy and the side frames only have a simple structure for placing the support rollers, the tilting of the support rollers will increase the instability of the cable tray operation. Utility Model Content

[0004] To overcome the shortcomings and problems of existing technologies and ensure the stability of cable reel laying frame operation, this utility model provides a cable reel laying frame for power construction.

[0005] This utility model is achieved through the following technical solution:

[0006] A cable reel laying frame for power construction includes a support rod for loading the cable reel and two opposing side frames. The two ends of the support rod are respectively mounted on one side frame. Each side frame includes two opposing side support parts, and each side support part has a lifting groove on its opposite surface. The lifting groove is connected to a support seat for supporting the support rod. A lifting screw is installed in the lifting groove, and each end of the support seat is connected to a lifting screw. A drive shaft is provided on the side frame, and both lifting screws are connected to the drive shaft and driven to rotate by the drive shaft. A transmission rod connects the two drive shafts, and at least one drive shaft is connected to a rotation drive device.

Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , 2 As shown in Figure 3, a cable reel laying frame for power construction includes a support rod 160 for mounting the cable reel and two oppositely arranged side frames 100. Both ends of the support rod 160 are respectively mounted on a side frame 100. Each side frame 100 includes two oppositely arranged side support parts 110, and each of the opposite surfaces of the two side support parts 110 is provided with a lifting groove 111. The lifting groove 111 is connected to a support seat 150 for supporting the support rod 160. The lifting groove 111 ensures the stability of the support seat 150 during subsequent lifting operations and prevents unnecessary movement of the support seat 150. The support seat 150 is provided with a rod mounting groove 151 for supporting the support rod 160. Two rotating wheels 152 are provided within the rod mounting groove 151, ensuring that the support rod 160 can rotate to facilitate the cable reel laying operation.

[0024] like Figure 4 As shown, both ends of the support rod 160 are provided with anti-detachment ring grooves 161. The support rod 160 is mounted on the support rod groove 151 through the anti-detachment ring grooves 161. The width of the anti-detachment ring groove 161 is wider than the width of the support base 150. The anti-detachment ring groove 161 ensures that the support rod 160 will not move axially when mounted on the support base 150, effectively preventing the support rod 160 from falling off. The support rod 160 is also provided with an installation ring groove 162. A limiting component 170 is provided in the installation ring groove 162. The limiting component 170 includes two interconnected limiting blocks 171. The limiting component 170 is detachable. After the cable reel is mounted on the support rod 160, the limiting component 170 is installed. The limiting component 170 can prevent the cable reel from moving axially along the support rod 160, ensuring the stability of the cable laying operation.

[0025] like Figure 1 , 2As shown in Figure 3, a lifting screw 120 is provided in the lifting slide 111. Both ends of the support seat 150 are connected to a lifting screw 120. When the lifting screw 120 rotates, it drives the support seat 150 to move along the lifting slide 111. The two lifting screws 120 ensure that both ends of the support seat 150 rise and fall together, preventing damage to the support seat 150 due to stress when driving the lifting of heavy cable reels. A drive shaft 130 is provided on the side frame 100. Both lifting screws 120 are connected to the drive shaft 130 and driven to rotate by it. A worm gear 121 is provided at the end of each lifting screw 120. The worm gear 121 is connected to a worm 122, which is connected to the drive shaft 130 via a gear structure. When the drive shaft 130 rotates, the two lifting screws 120 on the side frame 100 rotate synchronously, allowing both ends of the support seat 150 to rise and fall synchronously, ensuring the horizontal stability of the support seat 150.

[0026] like Figure 1 , 3 As shown in Figure 5, a transmission rod 140 connects the two drive shafts 130. The end of the transmission rod 140 is connected to the end of the drive shaft 130 through a concave-convex fit. Bolts pass through the drive shaft 130 and the transmission rod 140 to fix them together. The end of the drive shaft 130 has a polygonal connecting section 131, and the end of the transmission rod 140 has a connecting groove 141 that mates with the connecting section 131. The transmission rod 140 enables the drive shafts 130 on the two side frames 100 to rotate synchronously, achieving synchronous lifting and lowering of the two support seats 150, ensuring stable cable laying. The transmission rod 140 is detachable. When it is necessary to store or transport the equipment, the transmission rod 140 can be disassembled to reduce the space occupied by the equipment and make the equipment easier to handle. One of the drive shafts 130 is connected to a rotary drive device 180, which is a geared rotary motor that provides power for the rotation of the drive shaft 130. In this embodiment, all side frames 100 can be equipped with geared rotary motors. When dealing with heavy cable reels, the drive shafts 130 on both side frames 100 can be connected to geared rotary motors to reduce the load on a single geared rotary motor. The transmission rod 140 will ensure that the two drive shafts 130 rotate synchronously.

[0027] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
