A buried cable laying device

Abstract

This utility model relates to the field of cable technology, and in particular to a buried cable laying device, including a frame plate. An auxiliary structure is fixedly installed on the top of the frame plate. The auxiliary structure includes two support rods, two mounting covers, and two slide rails. Two fixed rods are rotatably installed inside the two mounting covers. Pulleys are fixedly installed on the outer surfaces of the two fixed rods. Conveyor belts are sleeved on the outer surfaces of the two pulleys. Through the auxiliary structure, when it is necessary to pull the cable, one end of the cable is inserted between the two conveyor belts, and then two servo motors are started simultaneously. This causes their output shafts to drive the fixed rods to rotate, thereby causing the conveyor belts to roll. Since the two servo motors rotate in opposite directions, the cable can be squeezed and quickly passed through the inside of the conveyor belts when they roll. This can assist in manually pulling the cable and moving the cable quickly, thus achieving the purpose of assisting in pulling the cable and reducing manpower consumption.

Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a buried cable laying device. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. Types of cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and many more.

[0003] There are still some shortcomings in the current process of laying buried cables: when laying existing cables, due to the excessive weight of the cables, they are generally moved manually, which results in significant manpower loss. At the same time, the cable surface is easily damaged by friction with the ground. Based on the shortcomings of existing technology, this utility model designs a buried cable laying device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a buried cable laying device that has the advantages of assisting in pulling the cable and reducing manpower consumption.

[0005] This utility model provides the following technical solution: a buried cable laying device, including a frame plate, an auxiliary structure fixedly installed on the top of the frame plate, the auxiliary structure including two support rods, two mounting covers and two slide rails; two fixed rods are rotatably installed inside the two mounting covers, pulleys are fixedly installed on the outer surfaces of the two fixed rods, a conveyor belt is sleeved on the outer surfaces of the two pulleys, a fixing ring is fixedly installed on the top of the two mounting covers, a servo motor is fixedly installed inside the two fixing rings, and one end of the output shaft of the two servo motors is fixedly connected to a fixing rod.

[0006] As a preferred embodiment of this utility model, the two support rods are fixed to the top of the frame plate, and a bidirectional lead screw is rotatably installed between the two support rods.

[0007] As a preferred embodiment of this utility model, one end of the bidirectional lead screw passes through the support rod, and a handwheel is fixedly installed at the end of the bidirectional lead screw that passes through the support rod.

[0008] As a preferred technical solution of this utility model, the outer surface of the bidirectional lead screw is threaded with first threaded blocks on both sides, and the two first threaded blocks are fixedly connected to the mounting cover.

[0009] As a preferred embodiment of this utility model, the two slide rails are fixed to the top of the frame plate, and the two mounting covers are slidably mounted with sliders at their bottoms.

[0010] As a preferred embodiment of this utility model, two support seats are fixedly installed on the top of the frame plate, and a winding roller is rotatably installed between the two support seats.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This buried cable laying device, through an auxiliary structure, allows for the pulling of cables when one end of the cable is inserted between two conveyor belts. Subsequently, two servo motors are simultaneously activated, causing their output shafts to drive a fixed rod to rotate, thereby causing the conveyor belts to roll. Since the two servo motors rotate in opposite directions, the cable is squeezed as the two conveyor belts roll, allowing it to quickly pass through the interior of the conveyor belts. This assists in manually pulling the cable and moving it quickly, thus achieving the purpose of assisting in pulling the cable and reducing manpower consumption. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 A buried cable laying device includes a frame plate 1. An auxiliary structure 4 is fixedly installed on the top of the frame plate 1. The auxiliary structure 4 includes two support rods 41, two mounting covers 45, and two slide rails 412. Two fixed rods 46 are rotatably installed inside the two mounting covers 45. Pulleys 47 are fixedly installed on the outer surface of the two fixed rods 46. A conveyor belt 48 is sleeved on the outer surface of the two pulleys 47. Fixed rings 49 are fixedly installed on the top of the two mounting covers 45. Servo motors 410 are fixedly installed inside the two fixed rings 49. One end of the output shaft of the two servo motors 410 is fixedly connected to one of the fixed rods 46.

[0021] Please see Figure 1-4 Two support rods 41 are fixed to the top of the frame plate 1, and a bidirectional lead screw 42 is rotatably installed between the two support rods 41. One end of the bidirectional lead screw 42 passes through the support rod 41, and a handwheel 43 is fixedly installed at the other end of the bidirectional lead screw 42 passing through the support rod 41. First threaded blocks 44 are threaded on both sides of the outer surface of the bidirectional lead screw 42, and the two first threaded blocks 44 are fixedly connected to the mounting cover 45. Two slide rails 412 are fixed to the top of the frame plate 1, and sliders 411 are slidably installed at the bottom of the two mounting covers 45. Two support seats 2 are fixedly installed on the top of the frame plate 1, and a winding roller 3 is rotatably installed between the two support seats 2.

[0022] By turning the handwheel 43, the bidirectional lead screw 42 can be rotated. Due to the limiting effect of the two slide rails 412 at the bottom, the two first threaded blocks 44 can drive the mounting cover 45 to move in opposite directions on the outer surface of the bidirectional lead screw 42, thereby adapting to cables of different sizes.

[0023] Please see Figure 5 A support structure 5 is fixedly installed on the top of the frame plate 1. The support structure 5 includes a fixed seat 51. A first support roller 52 is rotatably installed inside the two fixed seats 51. A threaded rod 53 is rotatably installed on the top of one fixed seat 51, and a limit rod 54 is fixedly installed on the top of the other fixed seat 51. A second threaded block 55 is threadedly installed on the outer surface of the threaded rod 53. Another second threaded block 55 is movably installed on the outer surface of the limit rod 54. A handle 57 is fixedly installed on the top of the threaded rod 53. A second support roller 56 is rotatably installed between the two second threaded blocks 55.

[0024] When pulling the cable, the cable is passed through the top of the first support roller 52, and then the throttle 57 is turned to rotate the threaded rod 53. Due to the limiting rod 54, the second threaded block 55 can move downward on the outer surface of the threaded rod 53 and the limiting rod 54, thereby allowing the second support roller 56 to contact the cable. The cable is supported by the first support roller 52 and the second support roller 56, improving the stability of cable winding and unwinding.

[0025] Working principle: When a buried cable laying device is used, firstly, when pulling the cable, the cable is passed through the top of the first support roller 52. Then, the throttle 57 is turned to rotate the threaded rod 53. Due to the limiting rod 54, the second threaded block 55 can move downward on the outer surface of the threaded rod 53 and the limiting rod 54, thereby allowing the second support roller 56 to contact the cable. The cable is supported by the first support roller 52 and the second support roller 56. Then, one end of the cable is passed between the two conveyor belts 48. Then, the two servo motors 410 are started simultaneously, thereby causing their output shafts to drive the fixed rod 46 to rotate, thus causing the conveyor belts 48 to roll. Since the two servo motors 410 rotate in opposite directions, the cable can be squeezed when the two conveyor belts 48 roll, so that it can quickly pass through the inside of the conveyor belts 48. This can assist manual pulling of the cable and move the cable quickly.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
