Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower construction equipment, and particularly relates to a cable laying equipment for water conservancy and hydropower construction. Background Technique

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. It is also called a water project. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the flow of water be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluice gates, water inlets, channels, aqueducts, raft channels, fishways, etc. to achieve their goals. During the construction of water conservancy projects, it is often necessary to use sluice gates to control the discharge, flow, and accumulation of water. These sluice gates often need to be connected to cables and controlled by electricity to open and close the gates. Therefore, during the installation of the sluice gates, a buried pipe and cable laying method is required to connect the sluice gates and cables.

[0003] In the prior art, a Chinese patent with the publication number of CN215518702U was proposed to solve the above-mentioned existing technical problems. The technical solution disclosed in the patent document is as follows: After retrieval, the Chinese patent publication number is CN217732318U, which discloses a cable laying equipment for power cables. In this patent, the replacement of the cable reel is facilitated through the first clamping block and the second clamping block. However, this replacement method requires rotation and disassembly, with many steps. At the same time, due to only the fixation of the left and right clamping blocks, the stability after fixation is relatively low. Also, during the use process, when laying cables, it is usually necessary to move the cable laying equipment to meet the cable laying requirements at different locations. However, during the intermediate movement process, since the cable reel is in a relaxed state at this time, when the cable laying equipment suddenly stops or accelerates during the movement process, the wire reel is prone to automatically rotate under the action of inertia, resulting in the relaxation of the outermost layer of the cable on the reel. As a result, during subsequent cable laying, it is necessary to manually wind up some of the loose cables first before continuing the cable laying steps, which affects the cable laying efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cable laying equipment for water conservancy and hydropower construction to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A cable laying device for water conservancy and hydropower construction, comprising a vehicle body, a support frame plate, a stepping motor and a wire laying rotating rod.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] The following further describes the present utility model in detail with reference to embodiments:

[0025] Such as Figures 1-4As shown in the figure, the utility model provides a cable pay-off device for water conservancy and hydropower construction, which includes a vehicle body 1, a support frame plate 2, a stepping motor 3 and a pay-off rotating rod 4. One end of the pay-off rotating rod 4 is provided with a wire reel positioning component 7 for fixing it. The wire reel positioning component 7 includes a positioning tooth 11 fixedly connected to the outer wall of one end of the pay-off rotating rod 4, a positioning fitting rod 10 clamped to the outer wall of the positioning tooth 11, and an electric push rod 13 rotatably connected to the outer wall of the positioning fitting rod 10 away from the positioning tooth 11. The positioning fitting rod 10 is divided into two, which are respectively installed on both sides of the positioning tooth 11, and the positioning tooth 11 is clamped simultaneously through the corresponding electric push rod 13, further enhancing the stable limiting effect on the pay-off rotating rod 4.

[0026] One end of the positioning fitting rod 10 is rotatably connected to one side of the support frame plate 2 through a shaft seat, and one end of the electric push rod 13 away from the positioning fitting rod 10 is rotatably connected to one side of the support frame plate 2 through a shaft seat.

[0027] A moving support component for auxiliary support is arranged below the pay-off rotating rod 4.

[0028] The moving support component includes a rotating rod support frame 5, a reinforcing collar 15 fixedly connected to the top end of the rotating rod support frame 5, and a bottom wheel 16 rotatably connected to the bottom surface of the rotating rod support frame 5. The inner wall of the reinforcing collar 15 is rotatably connected to an inner shaft collar 14, and the inner wall of the inner shaft collar 14 is movably sleeved on the outer wall of the pay-off rotating rod 4. A rotating rod chute 6 for the bottom wheel 16 to slide is opened on the upper surface of the vehicle body 1. The left and right ends of the rotating rod support frame 5 near the bottom surface are detachably fixedly connected to the upper surface of the vehicle body 1 through bolts. Threaded holes for installing the rotating rod support frame 5 are opened on the upper surface of the vehicle body 1. The rotating rod chute 6 is opened to the side of the vehicle body 1 close to the rotating rod positioning frame 9.

[0029] When different specifications of cable reels are assembled on the pay-off rotating rod 4, first slide the rotating rod support frame 5 out of the rotating rod chute 6, then sleeved the cable reel on the pay-off rotating rod 4 and move it to a position where it fits with the support frame plate 2. At this time, the rotating rod support frame 5 can be sleeved on one end of the pay-off rotating rod 4, then move the bottom wheel 16 along the inner wall of the rotating rod chute 6 towards the cable reel and make it fit with one end of the cable reel. Then fix the rotating rod support frame 5 on the vehicle body 1 through bolts, and limit the cable reel with a smaller specification through the inner shaft collar 14 to ensure that it can pay off the cable normally on the pay-off rotating rod 4.

[0030] Such as Figures 1-4As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the outer wall of the bottom wheel 16 is slidably connected to the inner wall of the rotating rod chute 6. One end of the wire-releasing rotating rod 4 close to the positioning teeth 11 is fixedly connected with a pulley 8, and the outer wall of the pulley 8 is rotationally connected to the output end of the stepping motor 3 through a belt. The end of the wire-releasing rotating rod 4 away from the positioning teeth 11 is movably connected with a rotating rod positioning frame 9, and the bottom surface of the rotating rod positioning frame 9 is detachably fixedly connected to the upper surface of the vehicle body 1.

[0031] One side of the support plate 2 is provided with a mounting hole adapted to the wire-releasing rotating rod 4, and the inner wall of the mounting hole is rotationally connected to the outer wall of one end of the wire-releasing rotating rod 4. One end of the positioning and fitting rod 10 is fixedly connected with a buffer spring 12.

[0032] Next, the working principle of the cable wire-releasing device for water conservancy and hydropower construction will be specifically described.

[0033] As Figures 1-4 shown, when the vehicle body 1 is in a non-wire-releasing state, the electric push rod 13 can be powered on and started, so that the electric push rod 13 pushes the positioning and fitting rod 10 towards the positioning teeth 11 and positions and locks the positioning teeth 11. At this time, the positioning teeth 11 cannot rotate, and thus the cable reel sleeved on the wire-releasing rotating rod 4 also cannot rotate, achieving the effect of preventing the cable reel from flipping due to inertia during the movement of the device and avoiding cable slack, which may affect subsequent wire-releasing.

[0034] Generally speaking, the present utility model has been described in detail above. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
