Description

Technical Field

[0001] This utility model relates to a special tool for installing terminals on the ends of steel wire ropes. Background Technology

[0002] In the use of wire ropes, it is often necessary to connect two rope ends or to connect two broken wire ropes.

[0003] Currently, the most common method for docking is using connecting terminals, especially in some specialized fields, such as the steel wire ropes used in highway steel wire rope fences. Firstly, during installation, it is necessary to connect two or more sections of steel wire rope into a whole. Secondly, during maintenance, it is necessary to reconnect broken steel wire ropes.

[0004] The connecting terminals generally include two clamps and a connector for connecting the clamps. In actual use, the ends of the wire ropes to be connected must first be inserted into the clamps, and then a conical wedge is used to wedge into the wire ends so that the wire ends are squeezed and become one with the clamps. Finally, the two clamps are connected to each other using the connector.

[0005] Currently, the conical wedge is driven into the end of the steel wire manually by striking it with a hammer. This method is labor-intensive, inefficient, and, in particular, difficult to guarantee quality.

[0006] Therefore, a special tool for installing terminals on the ends of steel wire ropes that can improve efficiency and ensure quality has emerged. Summary of the Invention

[0007] The purpose of this invention is to provide a special tool for installing terminals on the ends of steel wire ropes, which can improve efficiency and ensure quality.

[0008] The purpose of this utility model is achieved through the following structure: including a frame (11) and a pressing mechanism, the pressing mechanism being a telescopic mechanism with a power output end for linear travel, characterized in that: at least two clamps are provided in the travel path of the pressing mechanism, the clamps including a base (31) and a first upper pressure plate (34), a clamping hole (32) is provided between the base (31) and the first upper pressure plate (34), and the base (31) and the first upper pressure plate (34) are fixed by fixing bolts (33).

[0009] Further, the above-mentioned clamp is preferably: one end of the base (31) is hinged to one end of the first upper pressure plate (34), and a fastener (36) is provided between the other end of the base (31) and the other end of the first upper pressure plate (34). A second upper pressure plate (35) is provided in the clamping hole (32), and a fixing bolt (33) is provided on the first upper pressure plate (34). The second upper pressure plate (35) is connected to the end of the fixing bolt (33). Alternatively, the clamp is: one end of the base (31) is hinged to one end of the first upper pressure plate (34), and the other end of the base (31) is connected to the other end of the first upper pressure plate (34) by a fixing bolt (33).

[0010] Furthermore, it is preferable to provide a push rod (21) between the aforementioned pressing mechanism and the clamp. The push rod (21) is located in the sliding sleeve (23) and can slide in the sliding sleeve (23). One end of the push rod (21) is pressed against the power output end of the pressing mechanism, and the other end of the push rod (21) is opposite to the clamping hole (32) of the clamp.

[0011] Furthermore, a wedge support (25) is preferably provided on the end of the top rod (21) opposite to the clamping hole (32). The wedge support (25) is a cylindrical body that fits on the end of the top rod (21) and can slide on the top rod (21).

[0012] Furthermore, a second return spring (24) is preferably provided between the aforementioned wedge support (25) and the top rod (21).

[0013] Furthermore, in the above-mentioned fixtures, one of the fixtures preferably has a clamping stop (37) in the clamping hole (32), which is composed of at least one column with a semi-circular cross-section.

[0014] The aforementioned pressing mechanism includes a pressing rod (12), a transmission (16), and a drive (15).

[0015] The preferred pressing mechanism is a hydraulic mechanism: the pressing rod (12) is a hydraulic cylinder, the transmission (16) is a hydraulic pump, the driver (15) is a handle or motor, and is equipped with an oil tank (13) and a drive direction controller (14), the drive direction controller (14) being an oil circuit reversing device.

[0016] The pressing mechanism can also be a mechanical mechanism: the pressing rod (12) is a telescopic device composed of a sliding rod and a sliding groove, the transmission (16) is a gearbox, the driver (15) is a handle, and the drive direction controller (14) is a two-way ratchet and pawl mechanism.

[0017] In use, first select a connector with two pairs of clamps, insert the end of the wire rope into one clamp, and then place the wire rope after the clamp into the clamping hole (32) of the clamp base (31) away from the pressure rod (12). Press the first upper pressure plate (34) onto the base 31 and fix it with the fixing bolt (33). Place the clamp with the wire rope into the clamping hole (32) of the base 31 on one side of the top rod 12. Press the first upper pressure plate (34) onto the base 31 and fix it with the fixing bolt (33). Insert or align the tip of the wedge into the center of the wire rope in the clamp (if there is a wedge support 25, put it into the wedge support 25). Start the top pressing mechanism, and the wedge can be pushed into the middle of the wire rope in the clamp. The end of the wire rope is then connected and fixed with the clamp. The two ends of the wire rope with clamps can be quickly connected.

[0018] This invention is highly efficient and ensures installation quality when installing connection terminals at the ends of steel wire ropes, and in particular, it greatly reduces the labor intensity of manual labor. Attached Figure Description
