Description

Technical Field

[0001] The present application relates to the technical field of heading machines, and in particular to a heading machine quick stop valve. Background Art

[0002] In the field of prestressed construction, heading is a processing method that thickens the head of the steel bar by applying external force after heating. The heading machine is a tool used to make such headings. It is widely used in bridge construction, railway construction, large-scale hydraulic structures, industrial and civil buildings, and prefabricated component manufacturing. The heading machine needs to accurately control the flow and pressure of the oil when working to ensure that the steel wire can be properly clamped and headed. The role of the stop valve in the heading machine is to control the flow and stop of the oil to achieve this purpose. In addition, the stop valve can also be used to prevent the oil from flowing when it is not needed to avoid waste and accidents. For example, after the heading machine finishes working, the stop valve can close the flow channel of the oil to keep the oil in the heading machine still, which is convenient for preparation work for the next use. The existing stop valve has a slow cutoff speed and requires manual rotation of the valve switch to open and close, which is more troublesome and the response speed cannot keep up, affecting the rhythm of production. Utility Model Content

[0003] The purpose of the present application is to provide a quick shut-off valve for a heading machine, which solves the problem that the existing shut-off valve proposed in the background technology has a slow shut-off speed and requires manual rotation of the valve switch to open and close, which is rather troublesome, and the response speed cannot keep up, thus affecting the rhythm of production.

[0004] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a quick shut-off valve for a heading machine, comprising a valve body, an oil channel, a connecting rod and a main valve, an oil channel being opened on the inner left side of the valve body, a liquid inlet being opened at the bottom of the valve body, the liquid inlet being connected to the bottom end of the oil channel, the upper end of the oil channel being connected to the liquid outlet opened on the right side wall of the valve body, and a movable groove being opened on the inner right side of the valve body, the movable groove and the oil channel being connected via a connecting groove, the main valve being laterally slidably connected to the inner side of the connecting groove, the right end of the main valve being fixedly connected to a limiting plate, the right side wall of the limiting plate being fixedly connected to a hook, the left end of the connecting rod being movably connected to the hook, and the right end of the connecting rod being fixedly connected to a rotating shaft.

[0005] In this technical solution, the valve body is installed on the heading machine through the mounting seat, the oil enters the valve body through the liquid inlet, and leaves from the liquid outlet along the oil channel. The main valve slides horizontally in the connecting groove, thereby blocking and cutting off the oil channel. The movement of the main valve can be controlled by the turntable, the rotating shaft, the connecting rod and the hook. After the driving motor is started, it drives the transmission rod and the turntable to rotate. During the rotation, the turntable will pull the connecting rod, so that the main valve moves in the connecting groove to cut off the oil channel. There is no need to manually adjust the position of the main valve. The operation is convenient, which improves the convenience and practicality of the device. The unloading port and the sealing cover can facilitate the reflux of the oil. Due to the air pressure, the oil may not be able to reflux smoothly. After opening the sealing cover, the oil pipeline can be connected to the outside world. After the internal and external air pressures are consistent, the oil can be smoothly returned, which is convenient for pulling out for inspection and maintenance. After restarting, the air in the oil pipeline can be squeezed out, which improves the pushing and squeezing effect of the oil, and is highly practical.

[0006] As an optional solution of the technical solution of the present application, a transmission rod is movably installed below the inner wall of the movable groove, and one end of the transmission rod located on the inner side of the movable groove is fixedly connected to the turntable.

[0007] As an optional solution of the technical solution of the present application, a rotating shaft is movably installed on the surface edge of the turntable.

[0008] As an optional solution of the technical solution of the present application, the other end of the transmission rod is fixedly connected to the tail end of the transmission shaft of the drive motor, and the drive motor is fixedly mounted on the outer side wall of the valve body.

[0009] As an optional solution of the technical solution of the present application, a rubber plug is fixedly installed on the left end of the main valve.

[0010] As an optional solution of the technical solution of the present application, a pressure gauge channel is opened at the top of the valve body, a unloading port is opened at the top of the valve body on the right side of the pressure gauge channel, the bottom of the pressure gauge channel and the unloading port are connected to the oil channel, and a sealing cover is movably connected to the top of the unloading port.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present application can control the movement of the main valve through a turntable, a rotating shaft, a connecting rod and a hook. After the driving motor is started, it drives the transmission rod and the turntable to rotate. During the rotation, the turntable will pull the connecting rod, thereby moving the main valve in the connecting groove and cutting off the oil channel. There is no need to manually adjust the position of the main valve, which is easy to operate and improves the convenience and practicality of the device.

[0013] 2. The present application can facilitate the reflux of oil through the unloading port and the sealing cover. Due to the air pressure, the oil may not be able to reflux smoothly. After opening the sealing cover, the oil pipeline can be connected to the outside world. After the internal and external air pressures are consistent, the oil can be smoothly returned, which is convenient for pull-out inspection and maintenance. After restarting, the air in the oil pipeline can be squeezed out, which improves the pushing and squeezing effect of the oil and is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
