Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic tools, in particular to a 360-degree rotatable wire extractor. BACKGROUND

[0002] The hydraulic wire extractor is a special tool developed for the railway signal department, mainly used for the extraction of various signal wire pins in the railway signal system. The hydraulic wire extractor usually has a compact structural design. Its appearance is mostly made of metal material, and the surface may be treated to enhance rust resistance and durability. The overall structure of the wire extractor includes a hydraulic drive and a wire extraction mechanism, which includes a puller and other key components. The working principle of the hydraulic wire extractor mainly relies on the pushing of hydraulic oil. When the hydraulic drive is started, the wire extraction mechanism moves, and the hydraulic oil pushes the puller piston to move forward, and the front end of the piston is tightly pressed against the rail by the puller block. Then, the puller is moved backward by the puller oil cylinder through the trapezoidal thread, and the signal wire pin is pulled out from the rail hole through the opening at the front end of the puller.

[0003] The existing drive mechanism and wire extraction mechanism of the wire extractor have fixed angle positions, so the posture of using the curved line is also relatively rigid, which is not suitable for the extraction of signal wire pins in complex positions. That is, the wire extraction mechanism of the current wire extractor cannot rotate around the shaft to adjust the posture. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above technical problems and shortcomings: how to adjust or rotate the posture of the wire extractor, the present application provides a 360-degree rotatable wire extractor.

[0005] To achieve the above object and other related objects, the present application adopts the following technical solution:

[0006] A 360-degree rotatable wire extractor, comprising a drive mechanism and a wire extraction mechanism, a drive shaft is arranged on the drive mechanism, a universal connecting shaft is rotatably connected to the drive shaft, and the universal connecting shaft is connected to the wire extraction mechanism. The wire extraction mechanism rotates 360 degrees around the drive shaft through the universal connecting shaft.

[0007] Preferably, the wire extraction mechanism comprises a rotating top rod, a top block, and a puller. The rotating top rod is provided with a threaded segment and is threadedly connected to the puller. The lower end of the puller is provided with a puller claw and extends into the interior of the top block. The top of the top block is provided with an opening for the puller claw to pass through. The rear end of the top block abuts against the top rod.

[0008] Preferably, one side of the top rod is provided with a notch, and the puller claw is exposed at the notch.

[0009] Preferably, the drive mechanism is an electric hydraulic gun, an electric hydraulic machine, a hydraulic machine, or an electric motor.

[0010] Preferably, the threaded section of the rotating ejector pin is trapezoidal thread.

[0011] In summary, the present application has at least one of the following technical effects:

[0012] 1. The wire taking mechanism can rotate relative to the driving mechanism to change the posture, and can adapt to different working conditions or postures for construction operation. For such a tool, the wire taking mechanism can rotate 360 degrees during use, which is convenient for the operator to adjust the posture and improves the convenience of operation.

[0013] 2. The wire taking mechanism has a compact structure, reliable operation, and is more durable and less prone to damage.

[0014] 3. The use of electric drive can reduce the weight, facilitate carrying, and is very small and flexible in transportation. BRIEF DESCRIPTION OF DRAWINGS
