Description

Technical Field

[0001] The utility model belongs to the technical field of wire tightening machines, and in particular relates to a wire tightening machine for electric power construction. Background Art

[0002] At present, the power supply department is in the process of reconstruction and construction of 10KV high-voltage lines and 0.4LV lines. During the line erection process, the lines need to be replaced with new ones. When replacing the new lines, a long rope is usually tied to the end of the wire, and then the rope is passed over the cross arm, and then the rope is pulled to make the wire pass over the cross arm. Therefore, a wire tightening machine is needed to tighten the wire;

[0003] After checking the public (announcement) number; CN209626818U discloses a tensioning machine for electric power construction. This technology discloses "including a power car, a gearbox is provided at the rear end of the power car, and an active tensioning wheel is connected to the left and right ends of the gearbox respectively. Each active tensioning wheel is connected to a driven tensioning wheel for transmission. There is a wire arranger on each side of the power car, and a fixed shaft is provided above the gearbox. The two ends of the fixed shaft are provided with springs in sequence from the inside to the outside. The traction rope passing through the cross arm passes through the rope threading frame and is wound on the tensioning machine. The wire is then pulled onto the take-up drum through the wire arrangement device. The degree of engagement between the clutch wheel and the active sprocket is adjusted by adjusting the bolt. The tighter the engagement, the greater the friction. Driven by the upper hydraulic motor, the faster the take-up drum rotates, the greater the pulling force of the take-up drum on the traction rope. The traction rope wound on the two tension wheels is tightened. Driven by the tension wheel, the traction rope is gradually wound onto the take-up drum, and the cable is tightened. In this process, the operator only needs to operate the manual switch, manually control the switch and shift gears, which saves time and effort, etc.

[0004] When the above design is used, there is no need to manually pull the rope, which reduces the labor intensity of the workers. However, during the use of this device, since the tensioning device is difficult to separate from the power vehicle, the overall volume is large. For narrow, crowded or obstructed construction areas, it is difficult to move the power vehicle at a complex construction site, which brings inconvenience to the tensioning operation and is difficult to use flexibly according to actual needs, reducing the use effect of the device.

In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the above-mentioned design does not need to manually pull the rope when in use, thereby reducing the labor intensity of the staff. However, during the use of this device, the wire tightening device is difficult to separate from the power vehicle, resulting in a large overall volume. For narrow, crowded or obstructed construction areas, it is difficult to move the power vehicle at a complex construction site, which brings inconvenience to the wire tightening operation and is difficult to use flexibly according to actual needs, thereby reducing the use effect of the device." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a wire tightening assembly 2 and a conductor assembly 3 are added to the application document, and the power equipment involved in this product are all powered by an external power supply.

[0027] More specifically:

[0028] like Figure 1-Figure 4 As shown:

[0029] A tensioning assembly 2 is installed on the mounting seat 1, and the tensioning assembly 2 includes a diesel engine body 201 fixed on the upper surface of the mounting seat 1, a transmission 202 installed at the output end of the diesel engine body 201, and a winding drum 206 arranged on one side of the transmission 202. Connecting shafts are fixed at both ends of the winding drum 206, and the surface of the connecting shaft is rotatably connected to a fixing seat 204 through a bearing. Connecting rods 205 are fixed at the four corners between the two sets of fixing seats 204 by bolts. The connecting shaft and the output end of the transmission 202 are fixedly connected. Mounting holes 209 are provided at the four corners of the surface of the mounting seat 1, and card slots 212 are provided on both sides of the mounting seat 1, and fixing pins 210 are provided in the card slots 212.

[0030] The transmission 202 is fixedly connected to the mounting base 1 by bolts, and the upper surface of the mounting base 1 is fixed with symmetrically arranged side plates 203, and the two ends of the multiple groups of connecting rods 205 are respectively fixedly connected to the two groups of side plates 203;

[0031] A locking bolt 207 is threadedly connected to the surface of the winding drum 206 , and a circular groove is formed on one side of the surface of the winding drum 206 close to the locking bolt 207 .

Then, by starting the diesel engine body 201, the diesel engine body 201 can operate independently without external power and can adapt to various environmental conditions. The diesel engine body 201 drives the transmission 202 to rotate, and the transmission 202 drives the winding drum 206 to rotate, and the cable is wound by the winding drum 206. Therefore, during the winding process, the cable can be passed over the cross arm (not shown in the figure), and the cable can be tightened step by step. Through this operation, the cable can be tightened in various complex environments, which greatly improves the work efficiency, improves the use effect of the device, and meets the actual use needs.

[0033] Going further;

[0034] In an optional embodiment, an anti-slip pad 208 is fixed to one end of the locking bolt 207 .

[0035] In this embodiment, the anti-slip pad 208 is provided to effectively prevent the locking bolt 207 from squeezing the cable and causing deformation and damage to one end of the cable, while increasing the friction force and improving the fixing effect.

[0036] Going further;

[0037] In an optional embodiment, a placement groove 211 adapted to the fixing pin 210 is formed on the lower surface of the mounting seat 1 , and a buckle 213 is provided inside the placement groove 211 , and the buckle 213 is fixedly connected to the mounting seat 1 .

[0038] In this embodiment: the fixing pin 210 is removed from the buckle 213. By setting the placement groove 211 and the buckle 213, the fixing pin 210 can be stored when not in use to avoid loss. The buckle 213 is stuck on the surface of the fixing pin 210 to have a fixing effect.

[0039] Further,

[0040] In an optional embodiment, a wire assembly 3 is installed on the side plate 203, and the wire assembly 3 includes a fixed plate 303 fixed on the surface of the side plate 203, a reciprocating screw 307 rotatably connected between two groups of fixed plates 303 through a bearing, and a movable seat 304 threadedly connected to the surface of the reciprocating screw 307, the surface of the movable seat 304 is rotatably connected to a limiting wheel 305 through a bearing, a U-shaped ring 306 is fixed on the surface of the movable seat 304, and a limiting rod 308 is fixed between the two groups of fixed plates 303, a driving motor 301 is fixed on the surface of one group of fixed plates 303, and the output end of the driving motor 301 is fixedly connected to the reciprocating screw 307, and a battery 302 is fixedly installed on the upper surface of the mounting seat 1;

[0041] A moving hole matched with the limiting rod 308 is opened on the surface of the moving seat 304, and the moving seat 304 and the limiting rod 308 are slidably connected through the moving hole.

[0042] In this embodiment, when the winding drum 206 is winding the cable, the driving motor 301 is started at the same time, and the battery 302 is used to provide power to the driving motor 301, and the reciprocating screw rod 307 is driven to rotate by the driving motor 301. Since the reciprocating screw rod 307 is threadedly connected to the movable seat 304, the movable seat 304 is driven to reciprocate, and the movable seat 304 slides on the surface of the limit rod 308. The setting of the limit rod 308 can limit the movable seat 304, so that the movable seat 304 moves The process is more stable, as the movable seat 304 drives the limiting wheel 305 and the U-shaped ring 306 to move synchronously, the U-shaped ring 306 can limit the cable to prevent the cable from falling off the limiting wheel 305, and at the same time the limiting wheel 305 drives the cable to move back and forth. In this process, the winding drum 206 can achieve uniform winding operation, thereby avoiding the cable from being entangled or knotted during the winding process. This will not only reduce the winding speed, but also increase the number of manual interventions, further improving the use effect of the device.

[0043] Working principle and use process of the utility model: when the wire tightening machine for power construction is in use, when the use environment can be used on a power vehicle (not shown in the figure), the mounting seat 1 is installed on the vehicle for use through the mounting hole 209; when the use environment is not convenient for the power vehicle to use, the mounting seat 1 can be disassembled from the power vehicle, and then the staff will carry the device until it can be carried to the designated position for tightening the wire, and then the fixing pin 210 is removed from the buckle 213. By setting the placement groove 211 and the buckle 213, the fixing pin 210 can be placed and stored when not in use to avoid loss, and then the fixing pin 210 is wedged into the soil along the position of the card slot 212 of the mounting seat 1. The top of the fixing pin 210 is fitted with the surface of the mounting base 1 to limit the mounting base 1, so that the mounting base 1 is placed on the ground more stably to avoid deviation or folding during the tightening process. The cable (not shown in the figure) is then passed around the limiting wheel 305 and inserted into the circular groove (not shown in the figure). The locking bolt 207 is then rotated to squeeze and fix the cable, which is convenient for the cable to be rolled up later and improves the use effect of the device. At the same time, the anti-slip pad 208 is set to effectively prevent the locking bolt 207 from squeezing the cable and causing extrusion deformation and damage to one end of the cable. At the same time, the friction is increased to improve the fixing effect. Then, the diesel engine body 201 is started, and the diesel engine body 201 can The invention can operate independently without external power and can adapt to various environmental conditions. The diesel engine body 201 drives the transmission 202 to rotate, and the transmission 202 drives the winding drum 206 to rotate. The winding drum 206 is used to wind up the cable, so that during the winding process, the cable can pass over the cross arm (not shown in the figure), and the cable is tightened step by step. Through this operation, various complex environments can be coped with to tighten the cable, which greatly improves the work efficiency, improves the use effect of the device, and meets the actual use needs. When the winding drum 206 winds up the cable, the drive motor 301 is started at the same time, and the battery 302 provides power to the drive motor 301. The movable reciprocating screw rod 307 rotates. Since the reciprocating screw rod 307 and the movable seat 304 are threadedly connected, the movable seat 304 is driven to reciprocate. The movable seat 304 slides on the surface of the limit rod 308. The setting of the limit rod 308 can limit the movable seat 304, making the movable seat 304 more stable during movement. As the movable seat 304 drives the limit wheel 305 and the U-shaped ring 306 to move synchronously, the U-shaped ring 306 can limit the cable to prevent the cable from falling off the limit wheel 305. At the same time, the limit wheel 305 drives the cable to reciprocate. In this process, the winding drum 206 can achieve uniform winding operation, thereby preventing the cable from being entangled or knotted during the winding process.This will not only reduce the speed of winding, but also increase the number of manual interventions, further improving the use effect of the device.
