Description

Technical Field

[0002] Cable laying is one of the important tasks in power engineering construction. Cables may be laid in cable trenches, cable tunnels, cable ducts, etc. Cable laying is not always done along a straight line. Cables may also be laid in a bend according to environmental factors. When the cable is dragged, the cable at the bend is easily worn, and friction will be generated when the cable contacts objects at the bend, which increases the difficulty of cable dragging.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an auxiliary device for power engineering construction provided by an embodiment of the present invention includes a mounting plate 101, and a belt speed wheel 108 and a rotating shaft 109 rotatably connected to the upper end of the mounting plate 101, and also includes: two reversing wheels 105 rotatably connected to the upper end of the mounting plate 101 through an angle adjustment mechanism 2, the cable 8 sequentially passes around the two reversing wheels 105 and the belt speed wheel 108, and the angle adjustment mechanism 2 is used to adjust the reversing angle of the cable 8; an L-shaped support frame 106 is fixed to the upper end of the mounting plate 101, and a speed regulating motor 107 is fixed to the upper end of the L-shaped support frame 106, and the speed regulating motor 107 is located directly above the belt speed wheel 108, and an elastic pressing component 4 is provided on the mounting plate 101, and the elastic pressing component 4 is used to press the cable 8 on the belt speed wheel 108. On; the upper end of the mounting plate 101 is provided with a guide slide groove 110 and a guide slide groove 2 102, the guide slide groove 110 and the guide slide groove 2 102 are arranged perpendicular to each other, the guide slide groove 110 is slidably connected with a concave slider 111, the guide slide groove 2 102 is slidably connected with two guide blocks 103, a compression spring 104 is fixedly connected between the two guide blocks 103, and the two guide blocks 103 are rotatably connected with a connecting rod 112, and the ends of the two connecting rods 112 are rotatably connected to the concave slider 111; the L-shaped support frame 106 is provided with a control connection mechanism 5, when the cable 8 is in a tensioned state between the speed wheel 108 and the rotating shaft 109, the control connection mechanism 5 controls the rotating end of the speed regulating motor 107 to be transmission-connected with the speed wheel 108.

[0031] In the embodiment of the present invention, when in use, according to the angle at which the cable 8 is to turn, the angle adjustment mechanism 2 adjusts the positions of the two reversing wheels 105, so that the present invention can assist in laying cables at different angles. The cable 8 passes around the two reversing wheels 105, the speed wheel 108 and the rotating shaft 109 in sequence. Under the guiding action of the second guide slide groove 102, the compression spring 104 pulls the two guide blocks 103 to move toward each other. The two guide blocks 103 push the concave slider 111 through the two connecting rods 112, so that the concave slider 111 is against the portion of the cable 8 located between the speed wheel 108 and the rotating shaft 109. The elastic pressing component 4 presses the cable 8 on the speed wheel 108, and the speed regulating motor 107 is in a rotating state. When the cable 8 is dragged, the cable 8 is in a tensioned state. As the cable 8 is laid longer and longer, the dragging force required for the cable 8 will become greater and greater, and the cable 8 will gradually be straightened, so that the tensioned cable 8 pushes the concave slider 111, and the concave slider 111 The two guide blocks 103 are pushed by the two connecting rods 112, so that the two guide blocks 103 overcome the elastic force of the compression spring 104 and move in the opposite direction. When the two guide blocks 103 move in the opposite direction, the control connection mechanism 5 controls the rotating end of the speed regulating motor 107 to be connected with the speed wheel 108 for transmission. The speed regulating motor 107 drives the speed wheel 108 to rotate, and the speed wheel 108 drives the cable 8 to move, thereby assisting the laying of the cable 8. When the cable 8 is stopped, as the speed wheel 108 drives the cable 8 to move, the cable 8 between the speed wheel 108 and the rotating shaft 109 becomes loose, and the cable 8 does not generate thrust on the concave slider 111. The compression spring 104 pulls the two guide blocks 103 to move toward each other and reset. The control connection mechanism 5 controls the rotating end of the speed regulating motor 107 not to be connected with the speed wheel 108 for transmission, so that the speed wheel 108 stops conveying the cable 8, and then through the dragging force of the cable 8, the auxiliary conveying of the cable 8 is realized, thereby reducing the difficulty of cable laying.

When the guide block 103 moves back and forth, the transmission assembly 6 drives the vertical slider 502 to move up and down; the transmission assembly 6 includes a wedge block 601 fixed to the side wall of one of the guide blocks 103, a push groove 602 is arranged on the vertical slider 502, and a slope 603 is arranged on the push groove 602, and the wedge block 601 cooperates with the slope 603, and a compression spring 5 604 is arranged in the vertical slide groove 501, and the compression spring 5 604 is located at the lower end of the vertical slider 502.

[0039] In the embodiment of the present invention, in the initial state, the cable 8 is in a relaxed state, the vertical slider 502 is located at the upper part of the vertical slide groove 501, and the connecting shaft 503 is not inserted into the connecting hole 507; when the cable 8 is tensioned and the auxiliary transmission of the cable 8 is required, the guide block 103 drives the wedge block 601 to move toward the vertical slider 502, and the wedge block 601 pushes the inclined surface 603, so that the wedge block 601 overcomes the elastic force of the compression spring 5 604 and pushes the vertical slider 502 downward, the vertical slider 502 drives the connecting shaft 503 to move downward, the connecting shaft 503 is inserted into the connecting hole 507, and the rotating speed regulating motor 107 drives the driving shaft 505 to rotate, and the driving shaft 505 The transmission shaft 1 504 is driven to rotate, and the transmission shaft 1 504 drives the transmission shaft 2 506 to rotate through the connecting shaft 503 and the connecting hole 507, and the transmission shaft 2 506 drives the speed wheel 108 to rotate. In the present embodiment, the transmission shaft 2 506 is fixedly connected to the speed wheel 108; when the cable 8 is loose, the guide block 103 drives the wedge block 601 away from the vertical slider 502, and the compression spring 5 604 pushes the vertical slider 502 upward, and the vertical slider 502 drives the transmission shaft 1 504 to move upward, and the transmission shaft 1 504 drives the connecting shaft 503 to disengage from the connecting hole 507, thereby making the rotating end of the speed regulating motor 107 no longer connected to the speed wheel 108.

As the transmission shaft 1 504 rotates, when the connecting shaft 503 is coaxial with the connecting hole 507, the compression spring four 509 pushes the connecting shaft 503 to move downward, and the connecting shaft 503 is inserted into the connecting hole 507.

The two guide blocks 103 push the concave slider 111 through the two connecting rods 112, so that the concave slider 111 is against the portion of the cable 8 located between the speed wheel 108 and the rotating shaft 109, and the compression spring 3 403 pushes the sliding block 2 402 to move toward the speed wheel 108. The second sliding block 402 drives the support wheel 404 to move toward the speed wheel 108, so that the support wheel 404 and the speed wheel 108 clamp the cable 8, and the speed regulating motor 107 is in a rotating state. When the cable 8 is dragged, the cable 8 is in a tensioned state. As the cable 8 is laid longer and longer, the dragging force required for the cable 8 will become greater and greater, and the cable 8 will be gradually straightened, so that the tensioned cable 8 pushes the concave sliding block 111, and the concave sliding block 111 pushes the two guide blocks 103 through the two connecting rods 112, so that the two guide blocks 103 overcome the elastic force of the compression spring 104 and move in the opposite direction. When the two guide blocks 103 move in the opposite direction, the guide block 103 drives the wedge block 601 to move toward the vertical sliding block 502, and the wedge The block 601 pushes the inclined plane 603, so that the wedge block 601 overcomes the elastic force of the compression spring five 604 and pushes the vertical slider 502 downward, and the vertical slider 502 drives the connecting shaft 503 to move downward, and the connecting shaft 503 is inserted into the connecting hole 507, and the rotating speed regulating motor 107 drives the driving shaft 505 to rotate, and the driving shaft 505 drives the transmission shaft 1 504 to rotate, and the transmission shaft 1 504 drives the transmission shaft 2 506 to rotate through the connecting shaft 503 and the connecting hole 507, and the transmission shaft 2 506 drives the speed wheel 108 to rotate, so that the speed regulating motor 107 can drive the speed wheel 108 to rotate, and the speed wheel 108 drives the cable 8 to move, thereby assisting the laying of the cable 8. When the cable 8 stops being pulled, as the speed wheel 108 drives the electric When the cable 8 moves, the cable 8 between the speed wheel 108 and the rotating shaft 109 will become loose, and the cable 8 will not generate thrust on the concave slider 111. The compression spring 104 pulls the two guide blocks 103 to move toward each other and reset, and the guide block 103 drives the wedge block 601 away from the vertical slider 502. The compression spring 604 pushes the vertical slider 502 upward, and the vertical slider 502 drives the transmission shaft 1 504 to move upward, and the transmission shaft 1 504 drives the connecting shaft 503 to disengage from the connecting hole 507, so that the rotating end of the speed regulating motor 107 is not connected to the speed wheel 108 for transmission, and the speed wheel 108 stops conveying the cable 8, and then through the dragging force of the cable 8, the auxiliary conveying function of the cable 8 is realized, thereby reducing the difficulty of cable laying.
