Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a cable unwinding rack used in construction engineering. Background Art

[0002] Building construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. Cables are needed during the on-site construction of construction projects. Cables need to be unwound by unwinding equipment when in use; Publication (Announcement) No.: CN220165519U discloses a pay-out device for wires and cables, comprising a base plate, a support frame fixedly connected to the top of the base plate, a pay-out frame fixedly connected to the top of the support frame, and a wire roller rotatably connected inside the pay-out frame. The wire-releasing device for electric wires and cables pulls the electric wires and cables to drive the wire roller to rotate when the wire roller rotates. When the force of the wire roller rotating is greater than the elastic force of the first spring, the first spring will be compressed. Since the cross-sectional shape of the clamping rod is a trapezoid, the rotating wire roller will move the clamping rod to the side close to the box body. When the wire roller is subjected to natural force or inertia, the force generated will not compress the first spring, that is, the clamping rod will not move to the left, so the disc can be limited, and the wires and cables can be avoided from being entangled or knotted as much as possible. When more cables need to be released, the pull cap can be pulled to the left, and the movement of the pull cap drives the movable rod, the slide plate and the clamping rod to move, so that the clamping rod is separated from the clamping slot, and the contact of the wire roller can be limited.

[0003] The above-mentioned prior art solutions have the following defects: when it is necessary to transfer and lay out the wires within a certain area, it is necessary to use a lifting device to move the wire-laying device, which reduces the work efficiency of the transfer and the convenience of operation. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a cable unwinding rack for construction engineering, which improves the work efficiency of the transfer and the convenience of operation.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a cable unwinding stand for construction engineering, comprising: a cable reel assembly and a support shaft passing through the center of the cable reel assembly, the outer circles of both ends of the support shaft are respectively connected with bearings, the outer circles of the bearings are respectively connected with articulated clamping seat assemblies, the lower planes of the articulated clamping seat assemblies are respectively connected with lifting support frames, and the lifting support frames are connected with telescopic connecting rod assemblies;

[0006] The lifting support frame includes a lower support seat and a moving seat arranged above the lower support seat, a telescopic driving rod is connected between the moving seat and the lower support seat, and the upper plane of the moving seat is connected to the articulated clamping seat assembly.

[0007] By adopting the above technical scheme, when in use, the cable is wound on the cable reel assembly, the articulated clamping seat assembly is mounted on the corresponding bearing, the telescopic driving rod on the lifting support frame is operated to retract, so that the lower supporting seat on the lifting support frame is separated from the ground, and the construction personnel push the cable reel assembly to roll to the construction area, and there is no need to use lifting tools to transfer the cable unwinding rack, which reduces labor intensity and improves work efficiency and operational convenience. Next, the telescopic driving rod is operated to drive the lower supporting seat to move downward, and the lower supporting seat continues to move an appropriate distance after contacting the ground, so that the cable reel assembly is separated from the ground, that is, the telescopic connecting rod assembly supports the support shaft and the cable reel assembly, and the worker pulls one end of the cable for transmission, thereby achieving the purpose of unwinding the cable.

The inner sleeve can be adjusted along the length direction of the outer sleeve, which is suitable for the lifting support frame to support winding reel assemblies of different lengths. Since the U-shaped seat is connected to the end of the lower support seat on the other lifting support frame, the telescopic driving rods on the two lifting support frames can achieve asynchronous operation.

The battery can store electrical energy for the electric push rod. The electric push rod does not need to be connected to an external power source through wires, thereby improving the convenience of operation.
