Description

Technical Field

[0001] The invention belongs to the technical field of cable transportation and relates to a cable auxiliary transportation device for electric power construction. Background Art

[0002] With the development of social economy and the advancement of science and technology, the scale of power facility construction has continued to expand, and the demand for wires and cables has also increased. However, during the power construction process, the transportation and installation of wires and cables not only consumes a lot of manpower and material resources, but also easily causes damage to wires and cables, thus affecting the quality of the project.

[0003] At present, after the production of wires and cables is completed, the cables are usually wound on a winding drum. During transportation, the winding drum is lifted from the center of the winding drum by a lifting device and placed on the load-bearing platform of the transport vehicle; however, in order to facilitate lifting, the winding drum is usually placed on the load-bearing platform with its curved surface and fixed with straps. However, since the total weight of large cables and their winding drums can reach several tons, when the vehicle brakes suddenly, the winding drum is easy to break free from the straps and crash forward due to excessive inertia and insufficient friction, posing a major safety hazard; there are also transport vehicles specially equipped with curved bearing seats for transporting such round materials, but such special vehicles can only transport such materials and have a high purchase cost. In addition, during transportation, the curved surface of the winding drum directly contacts the load-bearing seat, and it rubs against the load-bearing seat continuously when shaking, which easily causes wear of the winding drum and cable, affecting product quality.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0029] A cable auxiliary transportation device for power construction, such as Figure 1-Figure 5 As shown, it includes a T-shaped frame 1, a sliding block 2, a connecting disk 3, a fixed block 4, a hanging ring 41, a transmission mechanism and an adjustment mechanism. The T-shaped frames 1 are provided with two and are symmetrically distributed on the left and right. The sliding blocks 2 are provided with two and are slidably installed on the two T-shaped frames 1 respectively, and can slide up and down along the T-shaped frame 1. The connecting disks 3 are provided with two and are rotatably connected to the sides of the two sliding blocks 2 that are close to each other. Four fixed blocks 4 are slidably connected to each connecting disk 3 along the circumferential direction. The fixed blocks 4 can slide radially along the connecting disk 3. The tops of the two T-shaped frames 1 are connected with hanging rings 41. A transmission mechanism for driving the fixed blocks 4 to move is provided between the connecting disk 3 and the fixed blocks 4. An adjustment mechanism for adjusting the spacing between the two T-shaped frames 1 is provided between the two T-shaped frames 1.

[0030] like Figure 3 and Figure 4 As shown, a hydraulic cylinder 5 is also included. The hydraulic cylinder 5 is fixedly mounted on the T-shaped frame 1 and the telescopic rod is connected to the sliding block 2, so that when the hydraulic cylinder 5 is in operation, it can control the lifting and lowering of the sliding block 2 through the telescopic rod thereon. In this embodiment, two hydraulic cylinders 5 are installed on each T-shaped frame 1 and are symmetrically distributed front and back, so that the hydraulic cylinder 5 is more stable when driving the sliding block 2 to move.

[0031] like Figure 3 and Figure 4As shown, it also includes a limit bar 6. The front and rear sides of the T-shaped frame 1 are connected to the limit bars 6. The two limit bars 6 are respectively located on the front and rear sides of the sliding block 2. The sliding block 2 is slidably connected to the limit bars 6. The sliding of the sliding block 2 is guided and limited by the limit bars 6 to avoid the position of the sliding block 2 from being offset when it moves.

[0032] like Figure 3 and Figure 4 As shown, the transmission mechanism includes an adjusting screw 71, an internal threaded sleeve 72 and a connecting rod 73. The adjusting screw 71 is rotatably connected between the sliding block 2 and the connecting disk 3. The adjusting screw 71 passes through the middle position of the sliding block 2 and the connecting disk 3. The two adjusting screws 71 are provided with internal hexagonal grooves on the sides away from each other. The adjusting screw 71 can be driven to rotate by inserting a hexagonal wrench into the internal hexagonal groove. The adjusting screw 71 is threadedly connected to the internal threaded sleeve 72. The internal threaded sleeve 72 and the four fixed blocks 4 are hingedly connected with connecting rods 73, so that the internal threaded sleeve 72 can squeeze the fixed block 4 to move through the connecting rod 73 when moving, so that the fixed block 4 expands outward to press against the inner wall of the cable to fix the cable.

[0033] like Figure 3-Figure 5 As shown, the adjustment mechanism includes a sleeve 81, a threaded rod 82 and an adjusting nut 83. The sleeve 81 is connected to the front side of the left T-shaped frame 1, and the threaded rod 82 is connected to the front side of the right T-shaped frame 1. The threaded rod 82 extends into the sleeve 81. The right side of the sleeve 81 is rotatably connected to the adjusting nut 83. The adjusting nut 83 is threadedly matched with the threaded rod 82, so that the adjusting nut 83 can drive the threaded rod 82 to move through the thread when rotating, thereby adjusting the distance between the two T-shaped frames 1.

[0034] When the cable needs to be transported, the auxiliary device can be used for transportation. When in use, the device is first placed on the carrying platform of the transport vehicle, and the winding drum 100 with the cable wound is placed between the two T-shaped frames 1. After placement, the adjusting screw 71 can be turned to drive the internal threaded sleeve 72 to move toward the inside of the winding drum 100 through the thread. When the internal threaded drum moves, it can drive the fixing block 4 to move outward through the connecting rod 73. The fixing block 4 can resist the inner wall of the winding drum 100 when moving, thereby fixing the winding drum 100. Then, the hook of the crane can be hooked on the hanging ring 41 to lift the device and the winding drum 100, and then the device can be hoisted onto the carrying platform of the transport vehicle. The cable can be transported by the device. In this way, the cable can be transported by the device, and during the transportation, the cable reel 100 can be lifted up to avoid friction between the cable reel 100 and the supporting base, and to avoid rolling during the placement process, which is safer to use. In the actual operation, the distance between the two T-shaped frames 1 can be controlled according to the size of the cable reel 100. Specifically, the threaded rod 82 is driven to move left and right by rotating the adjusting nut 83, thereby driving the T-shaped frame 1 on the right to move left and right for adjustment. The sliding block 2, the connecting plate 3 and the fixed block 4 can also be driven to move up and down by controlling the extension of the telescopic rod of the hydraulic cylinder 5, and the adjustment is made according to the height of the middle position of the cable reel 100.

[0035] like Figure 6 and Figure 7 As shown, it also includes a positioning mechanism, which includes a sliding frame 91, an elastic member 98, a pressure rod 92, a connecting rack 94, a convex shaft 95, a positioning claw 96 and a transmission gear 97. The lower part of the side where the two T-shaped frames 1 are close to each other is slidably connected to the sliding frame 91, and four elastic members 98 are connected between the top of the sliding frame 91 and the T-shaped frame 1. The elastic member 98 is a strong spring. The side where the sliding frames 91 on both sides are close to each other is connected to two pressure rods 92 that are symmetrically arranged in front and behind. The front and rear sides of the sliding frame 91 are both provided with inclined grooves 93. The upper part of the front and rear sides of the sliding frame 91 is slidably connected to the connecting rods 92. Rack 94, the sides of the two connected racks 94 close to each other are connected with a convex shaft 95, the convex shaft 95 is located in the inclined groove 93, so that the sliding frame 91 can drive the convex shaft 95 to move through the inclined groove 93 when sliding, and the four positioning claws 96 are provided, two of which are rotatably connected to the side of the threaded rod 82 and the sleeve 81 away from each other, and the other two positioning claws 96 are rotatably connected to the rear sides of the sides of the two T-shaped frames 1 close to each other. The four positioning claws 96 are all connected with a transmission gear 97, and the transmission gear 97 is meshed with the connected rack 94, so that the movement of the connected rack 94 can drive the transmission gear 97 to rotate.

[0036] When the device is placed on the carrying platform of the transport vehicle, the telescopic rod of the hydraulic cylinder 5 can be controlled to retract and drive the sliding block 2, the connecting disk 3 and the winding disk 100 to move downward. When the winding disk 100 moves downward, it will squeeze the pressure rod 92 to move downward, and the pressure rod 92 moves downward to drive the sliding frame 91 to move downward, and the elastic member 98 is stretched, and the sliding frame 91 moves downward and squeezes the two convex shafts 95 away from each other through the inclined groove 93. The two convex shafts 95 move away from each other and drive the two connecting racks 94 to move away from each other. When the two connecting racks 94 move away from each other, they poke the two transmission gears 97 to rotate. When the transmission gear 97 rotates, it can drive the positioning claws 96 to rotate, and the positioning claws 96 on the front and rear sides swing and resist the front and rear sides of the carrying platform. If the front and rear positions of the T-shaped frame 1 on the carrying platform are offset, the positioning claws 96 will resist the carrying platform in advance during the movement. At this time, the positioning claws 96 continue to move and will drive the entire T-shaped frame 1 to move together, so that the T-shaped frame 1 is stored in the center of the carrying platform, and can also be limited by the positioning claws 96.

[0037] like Figure 8 and Fig. 9 As shown, a moving mechanism is also included, and the moving mechanism includes a cylinder 101, a connecting frame 102 and an electric roller 103. The cylinder 101 is installed on each of the two T-shaped frames 1. The connecting frame 102 is connected to the telescopic rod of the cylinder 101. A plurality of electric rollers 103 are evenly installed on the connecting frame 102. A plurality of openings for the electric rollers 103 to pass through are opened at the lower part of the T-shaped frame 1. The electric roller 103 can move downward through the opening and contact the bearing plane, and then the electric roller 103 can be controlled to rotate to drive the transportation device to move.

[0038] When the device needs to be moved on the same plane, the telescopic rod of the cylinder 101 can be controlled to move downward to drive the connecting frame 102 and the electric roller 103 to move downward. After the electric roller 103 contacts the plane during movement, the electric roller 103 continues to move downward. At this time, the T-shaped frame 1 is lifted up, so that the bottom of the T-shaped frame 1 no longer contacts the plane. Then, the electric roller 103 can be controlled to rotate to drive the device to move, which is more convenient to move.

[0039] like Fig. 9 and Fig.10 As shown, it also includes a fixing mechanism, which includes a cylinder body 111 and a piston rod 112. A plurality of cylinder bodies 111 are evenly spaced and connected to the lower part of the T-shaped frame 1. A plurality of suction grooves that are the same in number as the cylinder bodies 111 are evenly spaced and provided at the bottom of the T-shaped frame 1. The bottom of the cylinder body 111 is open and connected to the suction groove at the bottom of the T-shaped frame 1. A piston rod 112 is slidably connected to the upper part of the cylinder body 111. The top of the piston rod 112 is connected to the connecting frame 102, so that the movement of the connecting frame 102 can drive the piston rod 112 to move.

[0040] like Fig.10 As shown, a sealing gasket 12 is also included. The bottom of the suction groove is connected to the sealing gasket 12. The sealing gasket 12 is in contact with the bearing plane, which can increase the sealing performance between the T-shaped frame 1 and the bearing plane.

[0041] After placing the device on the load-bearing platform, the telescopic rod of the control cylinder 101 is retracted to drive the connecting frame 102 to move upward. During the upward movement, the connecting frame 102 can drive the piston rod 112 to move upward. During the upward movement, the piston rod 112 can generate negative pressure between the cylinder body 111 and the suction groove, thereby adsorbing the entire device on the load-bearing plane. The sealing gasket 12 can increase the airtightness between the device and the load-bearing plane to avoid air leakage. In this way, the device can be adsorbed on the load-bearing plane to assist in fixing the device.

[0042] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
