Description

Technical Field

[0001] This utility model relates to the field of power installation technology, specifically to a power construction cable laying vehicle with anti-tipping function. Background Technology

[0002] Cable laying vehicles are widely used in the power industry for laying cables and changing their direction during pipeline installation. They can improve work efficiency, reduce pipeline damage, and are one of the key tools for tension cable laying operations.

[0003] Chinese utility model patent CN222915493U discloses a power construction cable laying pulley, which includes "using an outer frame 1 as the main support, when in use, the outer frame 1 is placed and fixed on the ground, and then the cable is laid through the cable laying wheel 6 inside the rotating ring 2. Then, the rotating adjustment component 4 applies resistance to the rotating ring 2 to keep it stable on the fixed frame 5, while at the same time, when the cable laying wheel 6 is subjected to a pulling deflection force that is greater than the resistance applied by the adjustment component 4 to the rotating ring 2, it will drive the entire rotating ring 2 to rotate." However, this device is only fixed by a fixing pin, and the adjustment component is biased to one side, which changes the overall center of gravity and is not conducive to the stability of the device. Utility Model Content

[0014] By adopting the above technical solutions, the stability of the overall structure can be guaranteed.

[0015] To achieve clamping and limiting of the pay-off reel when not in operation, preventing the reel from rolling during movement: Further configured as follows: the limiting mechanism includes a limiting chamber, and the upper part of the limiting chamber is symmetrically provided with a sliding groove. A first spring is fixedly connected to the inner wall of the symmetrical side of the sliding groove, and a wedge-shaped slider is fixedly connected to the free end of the first spring.

The vertical center lines of the rotating shaft 3, the cable laying roller 4 and the limiting mechanism 5 are aligned. The anti-automatic retraction mechanism 6 includes a movable plate 601. V-shaped frames 602 are symmetrically arranged on opposite sides of the top of the two movable plates 601. A pressure roller 603 is arranged between opposite sides of a set of V-shaped frames 602. A bidirectional lead screw 604 is threadedly connected to the bottom of the movable plate 601. The two ends of the bidirectional lead screw 604 are rotatably connected to opposite sides of two support columns 605. One end of the bidirectional lead screw 604 passes through one side of the support column 605 and is fixedly connected to a handle 606 on the outside.

[0022] In this embodiment, as Figure 4 As shown, the movable plate 601, V-shaped frame 602 and pressure roller 603 are a group and multiple groups are provided, and the multiple groups of movable plates 601, V-shaped frame 602 and pressure roller 603 are symmetrically distributed about the horizontal center point of the bidirectional lead screw 604.

[0023] In this embodiment, as Figure 4 As shown, multiple pressure rollers 603 are grouped in pairs, and the outer walls of one group of pressure rollers 603 overlap in the vertical direction. The two groups of pressure rollers 603 are distributed in a matrix in the vertical direction, and the central area of ​​the two groups of pressure rollers 603 forms a space for the cable to pass through.

[0024] In this embodiment, as Figure 2 As shown, the frame mechanism 2 includes a frame body 201, and a U-shaped groove 202 is provided on the top of the frame body 201. An arc-shaped locking block 203 is movably fitted on the inner wall of the U-shaped groove 202.

[0025] In this embodiment, as Figure 2 As shown, the frame body 201 has an overall trapezoidal structure with a smaller top and a larger bottom, and the inner wall of the U-shaped groove 202 is movably fitted with the rotating shaft 3, and the arc-shaped card block 203 is movably overlapped with the outer wall of the rotating shaft 3.

[0026] In this embodiment, as Figure 3As shown, the limiting mechanism 5 includes a limiting chamber 501, and the upper part of the limiting chamber 501 is symmetrically provided with a sliding groove 502. A first spring 503 is fixedly connected to the inner wall of the symmetrical side of the sliding groove 502, and a wedge-shaped slider 504 is fixedly connected to the free end of the first spring 503. A horizontal plate is provided on the side of the wedge-shaped slider 504 near the frame body 201, and a second spring 505 is fixedly connected to the bottom of the horizontal plate. A pin head 506 is fixedly connected to the free end of the second spring 505, and a number of pin holes 507 are evenly distributed on the top side of the limiting chamber 501 near the sliding groove 502. The top wedge-shaped surface of the wedge-shaped slider 504 is movably connected to the bottom outer wall of the wire feeding roller 4.

[0027] The working process of this power construction cable laying vehicle with anti-tipping function is as follows: First, the equipment is moved to the work area using the self-locking casters 7. The self-locking casters 7 include a mounting base, bolts, nuts, support legs, and casters. Turning the bolts moves the support legs downwards, allowing them to contact the ground and continue moving until the casters leave the ground. Then, tightening the nuts ensures the transfer mechanism is placed stably. When moving the equipment, turning the bolts moves the support legs upwards, allowing them to move away from the ground and continue moving until the casters contact the ground. Then, tightening the nuts ensures the transfer mechanism is placed stably. The two ends of the rotating shaft 3, which is fitted with the wire feeding roller 4, are placed into the U-shaped grooves 202 on the top of the symmetrically distributed frame body 201. The arc-shaped locking block 203 is inserted into the U-shaped groove 202 with its arc-shaped surface facing down, so that the arc-shaped locking block 203 fits tightly with the rotating shaft 3. The arc-shaped locking block 203 is fixed with bolts to prevent the wire feeding roller 4 from flipping out of the U-shaped groove 202 during the wire feeding process. One end of the cable wound around the outside of the wire feeding roller 4 passes through the space in the middle of the multiple pressure rollers 603. When the cable is fed to a suitable length, the throttle 606 is turned to make the bidirectional lead screw 604 rotate, which drives the two moving plates 601 to move towards each other, so that the pressure rollers 603 between the V-shaped frames 602 are close to each other. The wire feeding roller 4 is brought close to the cable and eventually clamps it tightly to prevent the cable from retracting automatically. When the wire feeding roller 4 is not in operation, the wedge-shaped sliders 504 on both sides of the bottom of the wire feeding roller 4 are moved to a suitable position so that the top wedge-shaped surface of the wedge-shaped slider 504 overlaps with the two side walls of the wire feeding roller 4 to achieve the limiting clamping operation of the wire feeding roller 4. Under the action of the compressed second spring 505, the pin head 506 is inserted into the corresponding pin hole 507 to keep the wire feeding roller 4 stable and prevent it from tipping over. When in operation, the pin head 506 is pulled out, and the stretched first spring 503 drives the wedge-shaped slider 504 to separate from the wire feeding roller 4, so that the wire feeding roller 4 can perform wire feeding operations.
