Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a wire-and-cable laying mechanism. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables. Cables are generally composed of one or more insulating cores and their respective coatings, total protective layers and outer sheaths. They are an important part of power construction operations.

[0003] During the laying process of existing wires and cables, a pay-off mechanism is required to pay out the wires and cables. The wires and cables are generally wound on the surface of a rotatable cylinder. When the wires need to be paid out, the wires and cables can be easily pulled out by rotating the cylinder by pulling the wires and cables. However, during the pulling process, due to inertia, the length of the wires and cables pulled out will be too long, and the wires and cables need to be manually wound back into the cylinder, which is inconvenient for the operator to use and increases the time required for power construction. At the same time, it also increases the workload of the operator, resulting in poor use of the existing wire and cable pay-off mechanism. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3The utility model provides a technical solution: a wire and cable pay-off mechanism, comprising a base plate 1, a main body component 200 is installed on the top of the base plate 1, and a positioning component 300 is installed on the top of the base plate 1. The main body component 200 and the positioning component 300 on the top of the base plate 1 are used in coordination with each other, so that the operator can operate conveniently, and the inertia generated during the pulling process of the wires and cables is reduced so that the cylinder wound with the wires and cables will not rotate excessively, thereby controlling the length of the wires and cables to be pulled out, so that the operator does not need to rewind the excessive wires and cables onto the outside of the cylinder, which is convenient for the operator to use and reduces the time required for power construction, thereby reducing the workload of the operator and effectively improving the use effect of the wire and cable pay-off mechanism.

[0025] It should be noted that two push rods symmetrically distributed on the left and right are fixedly connected to the top of the base plate 1, and four evenly distributed universal wheels are fixedly installed on the bottom of the base plate 1, so that the base plate 1 can be easily moved to the working point under the action of the universal wheels by pushing the push rods.

[0026] In this embodiment, the main body component 200 is a structure used for laying out wires and cables.

[0027] like Figure 1 As shown, the main body component 200 includes two support columns 201 respectively fixedly connected to the left and right sides of the top of the base plate 1, a rotating rod 202 is rotatably connected between the opposite sides of the two support columns 201, a cable drum 203 is fixedly connected to the outer side of the rotating rod 202, and the left and right ends of the rotating rod 202 are fixedly connected to limit blocks 204, and a hand wheel 205 is fixedly connected to the right side of the right limit block 204.

[0028] It should be noted that the length of the rotating rod 202 is equal to the distance between the opposite sides of the two support columns 201. The outer side of the rotating rod 202 is rotatably connected to the inner sides of the two support columns 201 through two bearings, so that the rotating rod 202 can rotate smoothly between the opposite sides of the two support columns 201.

[0029] In this embodiment, the positioning assembly 300 is a structure for positioning the laying of wires and cables.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the positioning assembly 300 includes two gears 301 fixedly connected to the outside of the rotating rod 202, and the two support columns 201 are provided with mounting grooves 302 on opposite sides thereof, and the inner side of the mounting grooves 302 is rotatably connected to a connecting rod 303, and the outer side of the connecting rod 303 is fixedly connected to a triangular block 304, and the two triangular blocks 304 are fixedly connected to the opposite sides thereof with a baffle 305, and the front and back sides of the triangular blocks 304 are fixedly connected to a No. 1 spring 306, and the right side of the left support column 201 is fixedly connected to a fixed Block 307, the inner side of the fixed block 307 is slidably connected with an insertion rod 308, the top of the left support column 201 is fixedly connected with a connecting block 309, the inner side of the connecting block 309 is slidably connected with a clamping block 310, the left side of the clamping block 310 is fixedly connected with a movable plate 311, the right side of the movable plate 311 is fixedly connected with a No. 2 spring 312, the left side of the insertion rod 308 is provided with two clamping grooves 313 for the clamping block 310 to be plugged in, and the top of the left baffle plate 305 is provided with a slot 314 for the insertion rod 308 to be plugged in.

[0031] It should be noted that the two gears 301 are symmetrically distributed on the left and right, and the bottom of the baffle 305 is meshed with the top of the corresponding gear 301, so that when the gear 301 rotates, the baffle 305 can be pushed to rotate, and the top and bottom ends of the connecting rod 303 are rotatably connected to the top and bottom of the mounting groove 302 through bearings, so that the connecting rod 303 can stably rotate on the inner side of the mounting groove 302.

[0032] In addition, the side of the No. 1 spring 306 away from the triangular block 304 is fixedly connected to the inner side of the mounting groove 302. When the triangular block 304 rotates, the corresponding No. 1 spring 306 can be stretched, so that the triangular block 304 is driven to rotate toward the side close to the initial position under the elastic recovery action of the No. 1 spring 306, thereby blocking the gear 301. A through hole is provided on the top of the fixed block 307 for the insertion rod 308 to pass through, so that the insertion rod 308 can be inserted into the inner side of the slot 314 through the through hole.

[0033] At the same time, a movable hole is opened on the right side of the connecting block 309 for the clamping block 310 to pass through, and the right side of the No. 2 spring 312 is fixedly connected to the left side of the connecting block 309, so that the clamping block 310 can slide on the inner side of the movable hole and can drive the No. 2 spring 312 to stretch. The distance between the two clamping grooves 313 is greater than the height of the slot 314. Therefore, when the clamping block 310 is inserted into the inner side of the bottom clamping groove 313, the insertion rod 308 is located above the slot 314, so that the right baffle 305 can rotate normally.

[0034] The working principle of the above embodiment is:

[0035] When it is necessary to lay out the wires and cables, move the bottom plate 1 to the working point and pull the movable plate 311 to the left to disengage the clamping block 310 from the inner side of the top clamping slot 313. At the same time, the No. 2 spring 312 is stretched and the insertion rod 308 is moved upward to disengage from the inner side of the slot 314. Under the elastic recovery action of the No. 2 spring 312, the movable plate 311 is driven to move to the right to make the clamping block 310 plugged into the inner side of the bottom clamping slot 313. The wires and cables are pulled to drive the cable drum 203 to rotate under the action of the two rotating rods 202. At the same time, the two gears 301 rotate, thereby pushing the baffle plate 305, stretching the corresponding No. 1 spring 306. Under the elastic recovery action of the No. 1 spring 306 The triangular block 304 is driven to rotate so that the baffle 305 returns to its original position, thereby blocking the gear 301 and preventing the cable drum 203 from excessively rotating due to inertia. This makes it convenient for the operator to use and can also normally lay out the wires and cables. When storage is needed, the hand wheel 205 is turned to rotate the right limit block 204, thereby driving the rotating rod 202 to rotate, and the wires and cables are rolled up and wound around the outside of the cable drum 203. According to the above principle, the movable plate 311 is pulled to the left so that the insertion rod 308 loses the insertion and fixation of the clamping block 310, and the insertion rod 308 is inserted into the inner side of the slot 314. At the same time, the clamping block 310 is inserted into the inner side of the top clamping groove 313 to complete the storage.

[0036] Compared with the prior art, the wire and cable pay-off mechanism, through the coordinated use of the main body component 200 on the top of the base plate 1 and the positioning component 300, can be convenient for the operator to operate, and the inertia generated during the pulling of the wires and cables can be reduced so that the cylinder wound with the wires and cables will not rotate excessively, thereby controlling the length of the wires and cables pulled out, and the operator does not need to rewind too much wires and cables onto the outside of the cylinder. While being convenient for the operator to use, it also reduces the time required for power construction, thereby reducing the operator's workload, effectively improving the use effect of the wire and cable pay-off mechanism, and solving the problem that the wires and cables are pulled out too long due to inertia during the pay-off process of the existing wire and cable pay-off mechanism.
