Description

Technical Field

[0001] This utility model belongs to the field of heating furnace technology and relates to an auxiliary anti-rotation device for the push rod of a walking beam heating furnace. Background Technology

[0002] After the steel billet enters the walking beam furnace, it stops on the water-cooled rollers. Four sets of pushers are located on the side of the billet. These pushers are driven by hydraulic cylinders and controlled by synchronous reversing valves. They simultaneously push the billet away from the water-cooled rollers and onto the top of the walking beam, from where the beam moves it step-by-step towards the furnace outlet. The pushers have two signals for forward and backward positioning, which participate in the step-by-step cycle control. The signal elements are located on the pusher base, and the signal detection retaining ring is mounted on the pusher rod. As the pusher rod pushes the billet, it must pass through the furnace wall. Occasionally, the pusher rod causes the signal detection retaining ring to rotate around its axis. Because the perpendicularity requirement between the signal detection retaining ring and the pusher rod is extremely high and difficult to achieve on-site, it is often impossible to achieve perfect perpendicularity. If the signal detection retaining ring rotates, it will cause the signal detection retaining ring and the signal detection switch to shift to the corresponding positions, leading to reduced signal detection accuracy or detection failure, thus affecting normal operation. Utility Model Content

[0003] The purpose of this invention is to address the problem of signal detection being affected by the rotation of the retaining ring in the prior art, and to provide an auxiliary anti-rotation device for the push rod of a walking beam furnace.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] An auxiliary anti-rotation device for the pusher rod of a walking beam furnace includes a pusher base. A pusher rod that can move along the length of the pusher base is provided on the pusher base. A signal detection retaining ring is fitted on the pusher rod. A guide rod is provided on one side of the pusher rod along the length of the pusher. A guide hole is provided on the signal detection retaining ring, and the guide rod passes through the guide hole.

[0006] Furthermore, the guide rod and the push rod are arranged parallel to each other.

[0007] Furthermore, the base of the steel pusher is equipped with a first signal detection switch and a second signal detection switch.

[0008] Furthermore, the front end of the steel pusher base is provided with a support frame, and the support frame is provided with a through hole, through which the steel pusher rod passes.

[0009] Furthermore, one end of the guide rod is fixed to the support frame, and the other end is provided with a connecting rod, which is fixed to the base of the steel pusher.

[0010] Furthermore, a hydraulic cylinder is provided at the rear end of the pusher base along the length of the pusher base, and the hydraulic cylinder is connected to the pusher rod.

[0011] The beneficial effects of this utility model are as follows: a guide rod is provided on one side of the push steel rod, and a guide hole is provided on the signal detection retaining ring, so that the guide rod passes through the guide hole. By restricting the guide rod, the signal detection retaining ring can be effectively prevented from rotating around the axis of the push steel rod, thus ensuring the detection effect of the signal detection switch; the structure is simple, the method of use is convenient, and the manufacturing cost is low.

[0015] The present invention will now be described in detail with reference to the accompanying drawings:

[0016] like Figure 1 and 2As shown, an auxiliary anti-rotation device for the pusher rod of a walking beam furnace includes a pusher base 1, a pusher rod 2 provided on the pusher base 1 along its length, and the pusher rod 2 can move back and forth along the length of the pusher base 1. Specifically, a support frame 3 is provided at the front end of the pusher base 1, and a through hole 4 is provided on the support frame 3, through which the pusher rod 2 passes. A hydraulic cylinder 5 is provided at the rear end of the pusher base 1 along its length, and the hydraulic cylinder 5 is connected to the pusher rod 2. The extension and retraction of the hydraulic cylinder 5 can drive the pusher rod 2 to move back and forth. A signal detection retaining ring 6 is fitted on the pusher rod 2, and the signal detection retaining ring 6 can move back and forth with the pusher rod 2. A guide rod 7 is provided on one side of the pusher rod 2 along the length of the pusher 1, and the guide rod 7 is arranged parallel to the pusher rod 2. Specifically, the guide rod 7... One end of the push rod 7 is fixed to the support frame 3, and the other end is provided with a connecting rod 8. The connecting rod 8 is fixed to the base 1 of the pusher. The signal detection retaining ring 6 is provided with a guide hole 9, and the guide rod 7 passes through the guide hole 9. When the signal detection retaining ring 6 moves with the pusher rod 2, it can move along the length of the guide rod 7 at the same time. Due to the restriction of the guide rod 7, the signal detection retaining ring 6 can be effectively prevented from rotating on the pusher rod 2 with the axis of the pusher rod 2 as the center. The base 1 of the pusher is provided with a first signal detection switch 10 and a second signal detection switch 11. The first signal detection switch 10 is located near the hydraulic cylinder 5, and the second signal detection switch 11 is located near the support frame 3. The first signal detection switch 10 and the second signal detection switch 11 can sense the signal detection retaining ring 6 and limit the pusher rod 2.

[0017] The method of using this utility model is as follows:

[0018] When the push rod 2 is pushing steel, the hydraulic cylinder 5 drives the push rod 2 to move along the length of the pusher base 1. During the movement, the signal detection retaining ring 6 moves along the length of the guide rod 7. The guide rod 7 restricts the movement of the signal detection retaining ring 6 on the push rod 2 around the axis of the push rod 2, ensuring that the detected part of the signal detection retaining ring 6 remains in place and does not affect the detection accuracy of the first signal detection switch 10 and the second signal detection switch 11, thus ensuring the operation of the push rod 2.
