Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a turnbuckle quick-tensioning structure. Background Technology

[0002] In the construction industry, wire ropes and strands are widely used in numerous scenarios, such as rope connections in tower crane hoisting operations, safety protection devices for construction hoists, suspension systems for suspended platform operations, and temporary reinforcement and traction of various building structures. Currently, among the traditional components used for tensioning, turnbuckles are a common type. They mainly consist of an adjusting rod with left and right threads, a nut, and hooks. Tensioning the wire rope is achieved by rotating the nut on the adjusting rod to change the distance between the hooks.

[0003] In actual construction environments, when using turnbuckles to tension wire ropes, the threaded fit between the nut and the adjusting rod requires overcoming significant friction, especially when tensioning larger-gauge or heavily tensioned wire ropes. Workers often find it difficult to turn the nut manually using only their hands. Therefore, auxiliary tools such as steel bars or crowbars are typically needed to manually tighten the nut. This operation not only requires considerable physical strength but is also extremely inconvenient. Manually tightening the nut is relatively slow. In large-scale construction sites, where a large number of wire ropes or strands often need to be tensioned, excessively long manual tensioning times using turnbuckles will inevitably extend the entire construction period, severely impacting project progress. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a quick tensioning structure for turnbuckles, which solves the problems of inconvenient adjustment, high manpower consumption and low construction efficiency of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A turnbuckle quick-tensioning structure includes a pull plate with an adjustment hole in the middle. A sleeve is provided at each end of the pull plate, coaxially arranged with its center line aligned with the plane of the pull plate. One end of each sleeve penetrates the end face of the pull plate, and the other end communicates with the adjustment hole. The structure also includes an adjustment screw that passes through the sleeve and extends into the adjustment hole. An adjustment nut is installed at the end of the screw extending into the adjustment hole. The sidewall width of the adjustment hole corresponding to one side of the sleeve is greater than the inner diameter of the sleeve, forming a limiting step between the sidewall of the adjustment hole and the sleeve. The adjustment nut can engage with this limiting step.

[0007] As an optimization, the pull plate is a rectangular flat plate structure.

[0008] As an optimization, the end of the adjusting screw opposite to the adjusting nut is formed with a lifting ring or hook for connecting to the steel strand.

[0009] Compared with the prior art, this application has the following advantages:

[0010] This utility model,

[0011] By adopting a sleeve structure and installing an adjusting nut at the end where the adjusting screw passes through the sleeve and extends into the adjusting hole, the adjusting screw and the sleeve are connected without threads. Compared with the traditional method of adjusting tension by rotating a pull plate, this method is more compatible with power tools. By using the sleeve head of an electric wrench, which is more compatible with power tools, to rotate the adjusting nut to adjust the tension, the labor consumption is greatly reduced and the construction efficiency is improved. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] In the diagram, 1 is a pull plate, 2 is an adjusting screw, 3 is an adjusting nut, 4 is an electric wrench socket head, and 5 is a socket-linked right-angle wrench. Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] For specific implementation: see: Figure 1 ,

[0016] An embodiment of a turnbuckle quick-tensioning structure includes a pull plate 1, which is a rectangular flat plate structure. A rectangular adjustment hole is formed in the middle of the pull plate 1. A sleeve is provided at each end of the pull plate 1, and the two sleeves are coaxially arranged with their center lines on the same plane as the plane of the pull plate 1. One end of each sleeve penetrates the end face of the pull plate 1, and the other end communicates with the adjustment hole. The structure also includes an adjustment screw 2, which passes through the sleeve and extends into the adjustment hole. An adjustment nut 3 is installed at the end of the adjustment screw 2 extending into the adjustment hole. A lifting ring or hook is formed at the end of the adjustment screw 2 opposite to the adjustment nut 3 for connecting to the steel strand. The sidewall width of the adjustment hole corresponding to one side of the sleeve is greater than the inner diameter of the sleeve, forming a limiting step between the sidewall of the adjustment hole and the sleeve. The adjustment nut 3 can fit against this limiting step.

[0017] During adjustment, an electric wrench socket head 4 is used, which can be fitted onto the adjusting nut 3. The socket head has an adjustment groove of a preset depth, and the cross-sectional shape of the adjustment groove matches the adjusting nut 3. When the electric wrench socket head 4 is rotated to drive the adjusting nut 3 to rotate, the adjusting screw 2 can be moved along its axial direction to adjust the tension.

[0018] It also includes a socket-linked right-angle wrench 5, which is L-shaped. One end of the socket-linked right-angle wrench 5 can be connected to the end of the electric wrench socket head 4 that is away from the adjustment groove. The socket-linked right-angle wrench 5 is an existing mature power tool, and its specific structure will not be described in detail. When in use, the electric wrench socket head 4 is installed on the drive end of the socket-linked right-angle wrench 5. The maximum torque can be set. Then, it is inserted into the adjustment hole, and the electric wrench socket head 4 is placed on the adjustment nut 3. The socket-linked right-angle wrench 5 is started to drive the nut to rotate. Of course, it can also be done manually, so that the adjustment screw 2 moves along its axis to achieve rapid adjustment of the tension.

[0019] By adopting a sleeve structure and installing an adjusting nut at the end where the adjusting screw passes through the sleeve and extends into the adjusting hole, the adjusting screw and the sleeve are connected without threads. Compared with the traditional method of adjusting tension by rotating a pull plate, this method is more compatible with power tools. By using the sleeve head of an electric wrench, which is more compatible with power tools, to rotate the adjusting nut to adjust the tension, the labor consumption is greatly reduced and the construction efficiency is improved.

[0020] During implementation, select a suitable adjusting screw based on site conditions and insert it into the sleeve of the pull plate. Manually screw in the adjusting nut at the end of the screw that extends into the adjusting hole, ensuring the adjusting screw extends at least three turns beyond the adjusting nut. Connect the lifting eye or hook at the other end to the fixed anchor point (such as embedded parts in the building structure, lifting hooks, etc.) and the steel wire rope or strand to be adjusted, ensuring a secure connection at both ends. Adjust the position of the steel strand or wire rope clamp to initially straighten and tighten it. Use an electric wrench connected to a socket-linked right-angle wrench and an electric wrench socket head, place it on the adjusting nut, adjust the electric wrench to the appropriate direction, and start the electric wrench until one adjusting screw is fully inserted into the electric wrench socket head or the steel wire rope is fully tensioned. If it is still not tensioned, remove the electric wrench and its socket head and place them on the other adjusting nut, continue starting the electric wrench until the steel wire rope or steel strand is fully tensioned. If a torque-controlled electric wrench is used, the torque value can be preset in advance to ensure even tension of each steel wire rope. By changing the diameter of the adjusting screw, the distance between the pull plates, and the diameter of the sleeve, it can adapt to different tensile force requirements.

[0021] Therefore, this utility model,

[0022] 1. Significantly improves tensioning efficiency by using an electric drive instead of the traditional manual operation (such as manually tightening nuts with the help of steel bars or pry bars when using turnbuckles), greatly reducing manpower consumption and lowering the labor intensity of workers;

[0023] 2. It eliminates the risk of personal injury caused by improper operation (such as excessive force, tool slippage, etc.) when manually using auxiliary tools, especially in high-altitude work scenarios, greatly improving worker safety. At the same time, precise tension control avoids safety hazards such as wire rope breakage and equipment damage caused by uneven or excessive tension, ensuring the safety of personnel and equipment on the construction site;

[0024] 3. The adjusting screws at both ends can be disassembled independently, which facilitates replacement and maintenance and reduces the cost of use;

[0025] 4. It can be easily integrated with existing construction equipment and processes without requiring significant changes to the construction workflow. It is easy to promote and apply, which helps to improve the mechanization and automation level of the entire construction industry and promotes the improvement of construction efficiency and quality;

[0026] 5. By pre-setting tension parameters, the tension of the wire rope is ensured to remain within the ideal range, avoiding problems such as uneven tension or over-tensioning caused by inaccurate judgment based on human experience. This helps improve the safety and stability of construction equipment and structures, and extends the service life of the wire rope and related equipment.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art can make various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and basis of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. Therefore, the embodiments of the present invention are merely illustrative examples and do not constitute a limitation on the present invention in any way.
