Description

Technical Field

[0001] This utility model belongs to the field of bridge engineering technology, and in particular relates to a galvanized steel strand connector that is easy to install and remove. Background Technology

[0002] Due to its advantages such as corrosion resistance, enhanced structural strength, and good electrical conductivity, galvanized steel strand has been used in the bridge engineering industry, especially in the main cables of suspension bridges, the cables of cable-stayed bridges, and the prestressing tendons of precast beams. The high strength and excellent corrosion resistance of galvanized steel strand make it perform well in harsh environments such as humidity and salt spray. When the length of the galvanized steel strand itself is not suitable for the work requirements, galvanized steel strand connectors are needed to connect two or more sections of galvanized steel strand to meet different work needs.

[0003] A search revealed a steel strand connector in patent document CN219863677U, but it still has the following drawbacks in practical use:

[0004] 1. The steel strand connector disclosed in the patent document with patent publication number CN219863677U achieves the connection and fixation between two sections of steel strand by setting two connectors, two pads, multiple bolt connection components and steel strand anchors. The bolt connection components include screws and nuts, with the nuts threaded on the circumference of the screws. The distance between the two connectors is adjusted by rotating the nuts, which realizes the assembly and disassembly of the two sections of steel strand. However, it is necessary to rotate the nuts on multiple screws, which increases the operation steps, makes it inconvenient to load and unload the steel strand, and requires a large amount of work.

[0005] 2. The steel strand connector disclosed in the patent document with patent publication number CN219863677U allows for the assembly and disassembly of two steel strands during the assembly and disassembly process. However, it is not convenient to perform preliminary positioning of the two connectors, and the connectors may even shift, resulting in misalignment of the two steel strands and making it difficult to connect the two steel strands.

[0006] To address these issues, we provide a galvanized steel strand connector that is easy to install and remove. Utility Model Content

[0007] The purpose of this utility model is to provide a galvanized steel strand connector that is easy to install and remove. By setting a locking component, the disassembly and assembly steps of the galvanized steel strand body are simplified, reducing the workload of disassembly and assembly. Furthermore, by setting a positioning component, the position of the connector head inside the fixing block can be quickly determined, which is beneficial for the subsequent locking and installation of the galvanized steel strand body. This solves the technical problem mentioned in the background art of the steel strand connector disclosed in the patent document with patent publication number CN219863677U.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a galvanized steel strand connector that is easy to install and remove. It includes a fixed clamping block, a movable clamping block on the lower surface of the fixed clamping block, and a locking assembly on the lower edge of the outer wall of the fixed clamping block. The locking assembly includes an upper ear fixedly attached to the lower edge of the outer wall of the fixed clamping block, and a lower ear fixedly attached to the upper edge of the outer wall of the movable clamping block. A damping bearing with an interference fit in the upper center of the upper ear has a lead screw rotatably connected to a vertical column. A ball nut on the periphery of the lead screw is located in the center of the lower ear. The lower end of a guide rod symmetrically and vertically fixed to the lower surface of the upper ear penetrates the lower ear. A positioning assembly is located inside the fixed clamping block, and a positioning groove is formed on the inner wall of the fixed clamping block. The positioning assembly includes a connector located inside the fixed clamping block, and a positioning rod is parallel to and fixed to the upper part of the outer wall of the connector. The positioning rod is slidably connected inside the positioning groove.

[0010] The present invention is further configured such that both the fixed clamping block and the movable clamping block are arc-shaped structures, and the fixed clamping block and the movable clamping block are combined to form a ring structure.

[0011] The present invention is further configured such that both the fixed clamping block and the movable clamping block have a fixed positioning block at the middle of their inner sides, and the positioning block has an arc-shaped structure.

[0012] The present invention is further configured such that the limiting blocks symmetrically fixed to the two side walls of the movable clamping block are arc-shaped structures, and the inner diameter of the limiting blocks is smaller than the inner diameter of the movable clamping block.

[0013] The present invention is further configured such that the upper ear block fixed to the outer wall edge of the fixed clamping block is away from the upper ear seat, the lower ear block fixed to the outer wall edge of the movable clamping block is away from the lower ear seat, and the guide shafts symmetrically and vertically fixed to the lower surface of the upper ear block pass through the lower ear block.

[0014] The present invention is further configured such that there are three positioning rods and three positioning slots, and both the positioning rods and the positioning slots are T-shaped structures.

[0015] The present invention is further configured such that the side wall of the connector has a rectangular array of wire holes, and the other side wall of the connector has a rectangular array of limiting holes. The inner diameter of the wire holes is smaller than the inner diameter of the limiting holes. A steel strand body is disposed through the wire holes. A steel strand anchor is disposed on the outer periphery of an annular clip disposed at the outer periphery of the steel strand body. The steel strand anchor is engaged with the inside of the limiting holes. The outer diameter of the steel strand anchor is larger than the inner diameter of the wire holes.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting a locking component, allows the galvanized steel strand body to be disassembled by rotating the screw clockwise, moving the ball nut downwards, causing the lower ear seat to move downwards away from the upper ear seat, and the movable clamping block to move downwards away from the fixed clamping block. Conversely, rotating the screw counterclockwise causes the movable clamping block to move upwards towards the fixed clamping block until the connector is clamped, thus installing the galvanized steel strand body. The above operations simplify the disassembly and assembly steps of the galvanized steel strand body and reduce the workload.

[0018] 2. This utility model sets up a positioning component, aligns the positioning rod with the positioning groove, pushes the connector head, and the positioning rod slides along the positioning groove. The connector head enters the interior of the fixing block until the connector head contacts the positioning block, thus achieving the positioning of the connector head. It has good stability, effectively prevents the connector head from shifting, facilitates the locking of the connector head in the later stage, and facilitates the installation of the galvanized steel strand body.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, please refer to Figure 1 , Figure 2 and Figure 4 This utility model is a galvanized steel strand connector that is easy to install and remove, including a fixed clamping block 1 and a movable clamping block 101. The galvanized steel strand can be clamped by adjusting the distance between the fixed clamping block 1 and the movable clamping block 101.

[0028] Specifically, the lower surface of the fixed clamping block 1 has a movable clamping block 101, the side wall of the movable clamping block 101 has a fixed limiting block 102, and the middle of the inner side wall of both the fixed clamping block 1 and the movable clamping block 101 has a fixed positioning block 103.

[0029] Furthermore, the fixed clamping block 1, the movable clamping block 101, the limiting block 102, and the positioning block 103 are all arc-shaped structures, and the inner diameter of the limiting block 102 is smaller than the inner diameter of the movable clamping block 101.

[0030] The operation process of this embodiment is as follows: after the connector 301 is inserted into the fixed clamping block 1, the movable clamping block 101 is adjusted upward to reduce the distance between the fixed clamping block 1 and the movable clamping block 101 until the connector 301 is clamped to achieve clamping of the galvanized steel strand; otherwise, the clamped connector 301 is released.

[0031] Example 2, please refer to Figure 1 and Figure 2Based on the first specific embodiment, a locking assembly 2 is provided. The locking assembly 2 includes an upper ear seat 201, a guide rod 201a, a lower ear seat 202, a ball nut 202a, a screw 203, an upper ear block 204, a guide shaft 204a, and a lower ear block 205. By simply rotating the screw 203, the distance between the upper ear seat 201 and the lower ear seat 202 can be adjusted, and the fixed clamping block 1 and the movable clamping block 101 can be opened and closed, thereby locking or loosening the steel strand body 303, realizing disassembly and assembly, simplifying the operation steps, and reducing the workload.

[0032] Specifically, the upper ear seat 201 is fixed to the lower edge of the outer wall of the fixed clamping block 1, and the lower ear seat 202 is fixed to the lower edge of the outer wall of the movable clamping block 101. The lower ear seat 202 is located below the upper ear seat 201. The damping bearing in the middle of the upper ear seat 201 has a vertically rotating connecting screw 203. The ball nut 202a on the periphery of the screw 203 is located in the middle of the lower ear seat 202. The lower surface of the upper ear seat 201 has a vertically fixed guide rod 201a. The lower end of the guide rod 201a passes through the lower ear seat 202. The upper ear block 204 is fixed to the other lower edge of the outer wall of the fixed clamping block 1, and the lower ear block 205 is fixed to the other lower edge of the outer wall of the movable clamping block 101. The lower surface of the upper ear block 204 has a vertically fixed guide shaft 204a. The lower end of the guide shaft 204a passes through the lower ear block 205.

[0033] Furthermore, the two guide rods 201a are symmetrically arranged, the two guide shafts 204a are symmetrically arranged, and the lead screw 203 has a right-hand helical thread structure;

[0034] The operation process of this embodiment is as follows: When the lead screw 203 is rotated clockwise, the lead screw 203 rotates clockwise, the ball nut 202a moves downward along the axial direction of the lead screw 203, the lower ear seat 202 and the lower ear block 205 move downward, the movable clamping block 101 moves downward, the distance between the fixed clamping block 1 and the movable clamping block 101 increases, and the clamped connector 301 is loosened; when the lead screw 203 is rotated counterclockwise, the movable clamping block 101 moves upward, the distance between the fixed clamping block 1 and the movable clamping block 101 decreases, and the connector 301 is clamped.

[0035] Example 3, please refer to Figure 1 , Figure 2 and Figure 3 Based on specific embodiment one and specific embodiment two, a positioning component 3 is provided. The positioning component 3 includes a positioning groove 104, a connector 301 and a positioning rod 302. The positioning rod 302 cooperates with the positioning groove 104 to facilitate quick positioning of the position between the connector 301 and the fixing block 1, and has good stability, which is beneficial for the subsequent clamping operation of the connector 301, thereby facilitating the clamping of the steel strand body 303.

[0036] Specifically, the inner wall of the fixed clamping block 1 has a positioning groove 104, and the upper outer side of the connector 301 has a fixed positioning rod 302. The positioning rod 302 is slidably connected inside the positioning groove 104. One side wall of the connector 301 has a rectangular array of wire holes 301a, and the other side wall of the connector 301 has a rectangular array of limiting holes 301b. The limiting holes 301b and the wire holes 301a are connected. The wire hole 301a has a through steel strand body 303, and the outer peripheral end of the steel strand body 303 has an annular clamp 303b. The steel strand anchor 303a on the outer periphery of the annular clamp 303b is locked inside the limiting hole 301b.

[0037] Furthermore, the two connectors 301 are symmetrically arranged, with a rectangular array of wire holes 301a and a rectangular array of limiting holes 301b. The inner diameter of the wire hole 301a is smaller than the inner diameter of the limiting hole 301b, and the outer diameter of the steel strand anchor 303a is larger than the inner diameter of the wire hole 301a.

[0038] The operation process of this embodiment is as follows: When the steel strand body 303 is pulled, the positioning rod 302 slides along the positioning groove 104, the connector 301 moves away from the positioning block 103, and the connector 301 moves out of the interior of the fixing clamp 1. Then, an external force is applied to the steel strand body 303 and the connector 301 in opposite directions, and the steel strand anchor 303a moves out of the interior of the limiting hole 301b, thereby realizing the disassembly of the steel strand body 303. Conversely, the steel strand body 303 is connected to the connector 301. When the connector 301 is installed, the positioning rod 302 slides along the positioning groove 104 until the connector 301 contacts the positioning block 103, and the connector 301 is locked inside the fixing clamp 1.
