Description

Technical Field

[0001] This utility model relates to the field of pipe quenching technology, and in particular to a hoisting fixture suitable for pipe quenching. Background Technology

[0002] In the quenching process of pipe fittings, due to the shape characteristics of the pipe fittings and the special working conditions during the quenching process, the stability requirements of the hoisting fixtures are extremely high. Traditional hoisting methods are often difficult to reliably fix the pipe fittings, and the pipe fittings are prone to deviation due to unstable clamping, which affects the quenching effect and may even cause safety hazards. At the same time, the fixing method is singular, and the pipe fittings may be unstable, which affects the stability of the hoisting process. Utility Model Content

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model embodiment is applicable to the hoisting fixture for quenching pipe fittings, which includes: a hoisting plate 1, a hoisting ring 18 fixedly connected to the upper surface of the hoisting plate 1, a bracket 14 fixedly connected to the lower surface of the hoisting plate 1, a bracket rod 8 rotatably connected inside the bracket 14 via a rotating shaft 12, a clamp 9 rotatably connected to the other end of the bracket rod 8 via a rotating shaft 12, a clamping plate 10 fixedly connected to the right surface of the clamp 9, and a stabilizing rod 11 fixedly connected to the right surface of the rotating shaft 12. The bracket 14, the bracket rod 8, and the clamp 9 are all located on the left and right sides of the hoisting plate 1, and on the left and right sides of the clamping plate 10 and the stabilizing rod 11.

[0021] Specifically, the lifting plate 1 serves as the basic load-bearing structure of the tooling, connecting the lifting system and the actuator (support, gripper, etc.). The support 14 and the support rod 8 form a movable support structure, enabling the opening and closing movement of the gripper 9. The support 14 is fixed to the lower surface of the lifting plate 1, serving as the mounting base for the rotating shaft 12. The support rod 8 is rotatably connected to the support 14 and the gripper 9 through the rotating shaft 12, forming a linkage mechanism of "support 14-support rod 8-gripper 9". When the support rod 8 rotates around the rotating shaft 12, it drives the gripper 9 to swing towards the center or outward, realizing the action of clamping or releasing the pipe. The gripper 9 directly contacts and fixes the pipe, ensuring the stability of the pipe posture during lifting and quenching. The clamping plate 10 ensures the structural stability of the gripper 9. The stabilizing rod 11 is connected between the rotating shafts 12, increasing the stability of the mechanism.

[0022] Reference Figure 1-4A base plate 2 is fixedly connected to the left and right surfaces of the lifting plate 1. An inclined plate is fixedly connected to the upper surface of the base plate 2. The upper end of the inclined plate is fixedly connected to the left and right sides of the lifting plate 1. A take-up box 3 is fixedly connected to the upper surface of the base plate 2. A mounting base 15 is fixedly connected to the upper surface of the base plate 1. A motor 16 is fixedly connected to the upper surface of the mounting base 15. A rotating shaft 17 is fixedly connected to the output end of the motor 16. A speed control mechanism is provided at the connection between the motor 16 and the rotating shaft 17. The rotating shaft 17 passes through the left surface of the take-up box 3. A take-up reel 13 is fixedly connected to the end of the rotating shaft 17 away from the motor 16. The take-up reel 13 is located inside the take-up box 3.

[0023] Specifically, the base plate 2 supports the take-up mechanism, and the inclined plate connects the base plate 2 and the lifting plate 1 to increase the stability of the take-up mechanism. The take-up box 3 houses the take-up reel 13, and the motor 16 is fixed to the mounting base 15. The output end is connected to the take-up reel 13 through the rotating shaft 17. When the motor 16 rotates forward, the take-up reel 13 winds the wire rope 4, pulling the support rod 6 upward. When it rotates in reverse, the wire rope 4 is released, the support rod 6 descends, and the speed of the rotating shaft 17 is adjusted by the speed control mechanism (such as a reducer or electronic speed control module) to prevent the wire rope 4 from being over-speeded during take-up and release, which could lead to impact or rope breakage.

[0024] Reference Figure 1-4 A steel wire rope 4 is fixedly connected to the side surface of the take-up reel 13. A hook 5 is fixedly connected to the end of the steel wire rope 4 away from the take-up reel 13. A support rod 6 is detachably connected to the inside of the hook 5 through a hook ring 7. The support rod 6 is located between the clamp 9 and the clamp plate 10. The hook ring 7 is set at the left and right ends of the support rod 6. A wire hole is provided on the upper surface of the base plate 2 and the lower surface of the take-up box 3. The steel wire rope 4 passes through the wire hole.

[0025] Specifically, one end of the wire rope 4 is fixed to the take-up reel 13, and the other end is connected to the hook ring 7 of the support rod 6 through the hook 5. The base plate 2 and the take-up box 3 are provided with wire holes to ensure that the movement path of the wire rope 4 is free from interference. The support rod 6 is located between the clamp 9 and the clamp plate 10, and both ends are detachably connected to the hook 5 through the hook ring 7. When in use, the support rod 6 is passed through the pipe, and the additional support of the pipe is achieved by the winding and unwinding of the wire rope 4, thereby ensuring the stability of the hoisting.

[0026] Working principle: The lifting system and the actuator (bracket 14, gripper 9, etc.) are connected by the lifting ring 18 on the lifting plate 1. The bracket 14, bracket rod 8, and gripper 9 form a linkage mechanism, which drives the gripper 9 to open and close (the gripper 9 fixes the pipe, the stabilizing rod 11 prevents swaying, the base plate 2 and the inclined plate support the wire take-up mechanism, the motor 16 drives the take-up wheel 13 to take up and release the wire rope 4, which is connected to the detachable support rod 6 via the hook 5. The gripper 9 is clamped or released by the lifting and lowering of the support rod 6 (the speed control mechanism prevents the wire rope 4 from being impacted by excessive speed). During operation, the motor rotates to raise the support rod 6, and the gripper 9 clamps the pipe; after being lifted to the quenching tank, it is kept fixed.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
