Description

Technical Field

[0001] The utility model relates to a cable laying pulley for electric power engineering construction, belonging to the field of electric power engineering equipment. Background Art

[0002] The cable turning pulley is an auxiliary tool for cable corner transportation. When the cable turning pulley is in use, a certain angle is formed between multiple guide wheels to transport the cable at an angle. However, since the position of the guide wheels on the cable turning pulley is relatively fixed, the angle of the cable turning pulley is relatively fixed, which makes it inconvenient to perform flexible corner transportation operations at different angles.

[0003] The Chinese utility model patent with application number CN202321357614.6 provides a cable corner pulley; although the device can adjust the angle freely, it relies on the shaft to drive the connecting plate to achieve the second guide wheel for angle adjustment; at the same time, the second guide wheel of the device is suspended as a whole; when the cable acts on the second guide wheel, the force of the cable will be applied to the mounting seat of the second guide wheel through the second guide wheel, and the mounting seat will apply the force to the connecting plate;

[0004] At this time, the connecting plate needs to bear the force from the cable. As we all know, the cables in power engineering have large diameters and heavy weights, so the force is very large. However, if a connecting plate is used to bear such a large force, the life of the connecting plate will be reduced.

[0005] In order to reduce this phenomenon, it is necessary to use a high-cost, strong-structured connecting plate; or reduce the length of the connecting plate; and reducing the length of the connecting plate means that the distance between the first guide wheel and the second guide wheel is reduced, which will reduce the span of the bearing force of the two guide wheels, causing the force from the cable to become more concentrated, affecting the stability of the entire equipment. Utility Model Content

[0006] The purpose of the utility model is to provide a cable laying pulley for electric power engineering construction, which can effectively solve the above-mentioned problems.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] It comprises a mounting plate, on which a fixed seat, two movable seats that move relatively to each other, and an adjusting component for controlling the movement of the movable seats are arranged;

[0009] Wherein, the fixed seat and the movable seat are both provided with guide wheels, and the movable seat is arranged on both sides of the fixed seat;

[0010] The adjustment component includes a mounting groove running through the upper and lower ends of the mounting plate, a rotating rod is arranged in the mounting groove, both ends of the rotating rod are provided with external threads with opposite thread directions, a moving block is arranged at the lower end of the moving seat, the moving block is placed in the mounting groove and connected to the external threads.

[0011] Further: a motor is installed at one end of the rotating rod.

[0012] Further: a mounting frame is arranged on one side of the mounting plate, and the motor is arranged on the mounting frame.

[0013] Furthermore: the fixed seat has the same structure as the movable seat, both of which are composed of two horizontal plates and support columns arranged between the horizontal plates; mounting columns are also arranged between the horizontal plates, and the guide wheel is rotatably arranged on the mounting columns.

[0014] Further: a stabilizing block is arranged in the middle of the installation groove, and the rotating rod passes through the stabilizing block and is rotatably connected to the stabilizing block.

[0015] The beneficial effects are:

[0016] In this device, the adjustment mode of the movable seat is changed to linear adjustment. When the rotating rod rotates forward, the movable block will perform threaded advancement to drive the movable seat to move relatively. The distance between the two movable seats decreases, which means that the angular amplitude of the cable becomes larger. When the rotating rod rotates reversely, the distance between the two movable seats increases, which means that the angular amplitude of the cable decreases. At the same time, the distance between the movable seat and the fixed seat increases, increasing the span of the cable-bearing force and transferring the cable force to the mounting plate, thereby increasing the service life of the equipment.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] See also Figure 1 , Figure 2 This is an embodiment of a cable laying pulley for electric power engineering construction of the utility model.

[0024] The utility model comprises a mounting plate 1, on which a fixed seat 2, two relatively movable seats 3 and an adjusting component 4 for controlling the movement of the movable seats 3 are arranged;

[0025] The fixed seat 2 and the movable seat 3 are both provided with guide wheels 5, and the movable seat 3 is arranged on both sides of the fixed seat 2;

[0026] The adjustment component 4 includes a mounting groove 6 that passes through the upper and lower ends of the mounting plate 1, a rotating rod 7 is arranged in the mounting groove 6, and both ends of the rotating rod 7 are provided with external threads 8 with opposite thread directions. A moving block 9 is arranged at the lower end of the moving seat 3, and the moving block 9 is placed in the mounting groove 6 and connected to the external thread 8.

[0027] In this device, the cable is firstly wound around the three guide wheels 5, and then the position of the movable seat 3 is adjusted as required, so as to achieve the purpose of adjusting the cable turning angle;

[0028] In the present device, the adjustment mode of the movable seat 3 is changed to linear adjustment. When the rotating rod 7 rotates forward, the movable block 9 will perform threaded advancement to drive the movable seat 3 to move relatively. The distance between the two movable seats 3 is reduced, which means that the angular amplitude of the cable becomes larger; when the rotating rod 7 rotates reversely, the distance between the two movable seats 3 increases, which means that the angular amplitude of the cable is reduced. At the same time, the distance between the movable seat 3 and the fixed seat 2 increases, thereby increasing the span of the bearing cable force and transferring the cable force to the mounting plate 1, thereby improving the service life of the equipment.

[0029] A motor 10 is mounted on one end of the rotating rod 7 .

[0030] The motor 10 of the device can facilitate automatic adjustment of the rotating rod 7, thereby improving the automation level of the equipment.

[0031] A mounting frame 11 is disposed on one side of the mounting plate 1 , and the motor 10 is disposed on the mounting frame 11 .

[0032] The purpose of the mounting frame 11 of the present device is to install the motor 10.

[0033] The fixed seat 2 and the movable seat 3 have the same structure, and are both composed of two horizontal plates 21 and support columns 22 arranged between the horizontal plates 21; a mounting column 12 is also arranged between the horizontal plates 21, and the guide wheel 5 is rotatably arranged on the mounting column 12.

[0034] In order not to affect the guiding of the cable, the mounting seat for mounting the guide wheel 5 is improved by using a support column 22 with a smaller width, thus providing a larger space for the turning corner of the cable.

[0035] A stabilizing block 13 is disposed in the middle of the mounting groove 6 , and the rotating rod 7 passes through the stabilizing block 13 and is rotatably connected to the stabilizing block 13 .

[0036] Since the rotating rod 7 of the device is long, it is subjected to a large force when rotating. Long-term use will affect the service life of the rotating rod 7. Therefore, a stabilizing block 13 is provided to provide a force to the rotating rod 7, help the rotating rod 7 to be more stable, and increase the service life of the rotating rod 7.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
