Description

A wire reel transport and pay-off vehicle for wire construction

technical field

The invention relates to an electric power pay-off device, in particular to a wire reel transport pay-off vehicle for wire construction.

Background technique

According to the relevant information currently available, some domestic manufacturers have developed and produced related wire pay-off vehicles for smaller-tonnage wire reels. Small force, mechanical transmission, can not rely on its own power to realize the loading and unloading of the wire reel. At the same time, from the relevant wire transportation equipment known so far, the wire reel bracket used in the existing construction is a split design, consisting of two left and right outriggers, which are temporarily installed during construction, and do not carry the walking mechanism itself, and need to be used for larger parts. Crane, manual installation is more intensive.

The wire pay-off car with mechanical transmission for equipment release and adjustment has low control accuracy, large mechanical impact, low safety, easy damage, and cannot rely on its own power to load and unload the wire reel. It needs to use a crane, which is expensive. At the same time, the main common problem of the existing wire transportation equipment is the difference in the walking characteristics of the equipment. Most wire pay-off racks are composed of left and right brackets and do not have a walking function. Large, not suitable for construction operations of UHV heavy-duty wire coils.

The wheel base of the foreign trailer-type wire pay-off vehicle cannot be adjusted, and it is only suitable for small-tonnage wire reels and wide roads, and the scope of use is limited.

Contents of the invention

Aiming at the defects in the prior art, the present invention provides a wire reel transport and pay-off vehicle for wire erection construction, which can greatly reduce the construction cost and improve the construction efficiency at the same time.

Specifically, the technical solution is: a wire reel transport and pay-off vehicle for wire construction, including a transport vehicle, a lifting device and a tension machine. The transport vehicle is composed of a rectangular frame and rollers. The rollers are arranged on the rectangular frame. Steering wheels are provided, and front plows are provided at both ends of the front beam of the rectangular frame; the lifting device is symmetrically arranged on the left and right sides of the rectangular frame, and the lifting device is composed of a hydraulic rod, a reel shaft and a support rod, and the hydraulic rod and the support rod Respectively hinged on the rectangular frame, the hydraulic rod and the support rod are connected by a rotating shaft, the upper end of the support rod is provided with a tile seat, and the two ends of the coil shaft pass through the interior of the tile seat; the tension machine is hinged on the outer surface of the upper end of the support rod.

The parts of the rectangular frame are connected by bolts, and one end of the rear beam is connected with the beam on the corresponding side by a rotating shaft.

The front plow is connected with the rectangular frame by a pin shaft.

When the tension machine is in a horizontal position, its axis is on the same straight line as the axis of the tile seat.

The steering wheel is provided with a drag bar.

The invention is low in cost and easy to use; the transport vehicle can pass through various complex terrains and walk stably through the traction of external force; the lifting device can directly carry out the lifting operation on the wire reel, which reduces the utilization rate of the lifting equipment, thereby reducing Construction cost; through the tension machine, the automatic and smooth unwinding operation can be realized, which reduces labor intensity and improves work efficiency.

Detailed ways

As shown in Figures 1 and 2, a wire reel transport and pay-off vehicle for stringing construction includes a transport vehicle, a lifting device and a tensioner 1. As shown in Figure 4, the transport vehicle is composed of a rectangular frame 2 and rollers 3. The roller 3 is arranged on the rectangular frame 2, the steering wheel 4 is arranged at the middle position of the front end of the rectangular frame 2, and the front plow 5 is arranged at the two ends of the front beam of the rectangular frame 2; the lifting device is symmetrically arranged on the left and right sides of the rectangular frame 2, as As shown in Figures 2 and 3, the lifting device is composed of a hydraulic rod 6, a support rod 7 and a reel shaft 8, and the hydraulic rod 6 and the support rod 7 are respectively hinged on the rectangular frame 2, and between the hydraulic rod 6 and the support rod 7 Connected by a rotating shaft, the upper end of the pole 7 is provided with a tile seat 9, and the inner surface of the tile seat 9 is provided with a bearing bush, and the two ends of the bobbin shaft 8 run through the interior of the tile seat 9;

The parts of the rectangular frame 2 are connected by bolts, which are easy to disassemble, thereby facilitating transportation and assembly. One end of the rear cross beam 10 is connected to the beam on the corresponding side by a rotating shaft. When in use, the rear cross beam 10 is opened, and the position of the transport vehicle is adjusted so that The pay-off reel enters the inside of the rectangular frame 2, inserts the reel shaft 8 through the center hole of the pay-off reel, adjusts the lifting device, puts both ends of the reel shaft 8 into the tile seat 9 and fixes it, and the hydraulic rod 6 is driven by the oil pump 11 control, the pay-off reel is held up by the hydraulic rod 6, the steering wheel 4 is provided with a drag bar 12, and the drag bar 12 is used for traction and movement; during the movement of the transport vehicle, the tension machine 1 is in a vertical position in the axial direction, thereby reducing the cost. The overall width of the invention improves the passability during the moving process, and the front plow 5 is connected with the rectangular frame 2 by a pin shaft, and the front plow 5 is lifted during the movement of the transport vehicle.

When reaching the wire-releasing position, place the front plow 5 on the ground to prevent the transport vehicle from shifting during the wire-releasing process, and rotate the tension machine 1 so that the axis of the tension machine 1 is in a horizontal state. When the tension machine 1 is in a horizontal position, its axis On the same straight line with the tile seat 9 axis. Use a coupling to connect the tension machine 1 with the reel shaft 8, start the tension machine 1, and the tension machine 1 drives the pay-off reel to rotate for pay-off. When the weight of the pay-off reel is too large, the rotation speed is accelerated due to its huge inertia Tension machine 1 provides braking force to it, so that the pay-off reel can always keep rotating at a constant speed, so as to achieve the purpose of smooth pay-off.
