Detailed Implementation

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] This utility model provides a heat treatment production line. Several embodiments are given below to describe the heat treatment production line provided by this utility model in detail.

[0033] The heat treatment production line provided in this embodiment, such as Figures 1 to 3 As shown, the system includes a mobile trolley 1 and multiple furnace bodies 2; the multiple furnace bodies 2 are spaced apart along a first direction; along a second direction, the mobile trolley 1 is positioned on one side of the multiple furnace bodies 2, and the mobile trolley 1 can slide along the first direction; a first limit switch 11 and a first trigger 12 are provided on the side of the mobile trolley 1 facing the furnace body 2, and the first trigger 12 is positioned above the first limit switch 11; each furnace body 2 has a second limit switch 24 on the side facing the mobile trolley 1; along the first direction, a second trigger 3 is provided on both sides of each second limit switch 24, and the second limit switch 24 is positioned above the second trigger 3; the first trigger 12 can collide with the second limit switch 24 to trigger the second limit switch 24; the second trigger 3 can collide with the first limit switch 11 to trigger the first limit switch 11; the second direction is perpendicular to the first direction.

[0034] Along the second direction, the moving trolley 1 is set on one side of the multiple furnace bodies 2, and the moving trolley 1 is spaced apart from the multiple furnace bodies 2.

[0035] The mobile trolley 1 can slide relative to multiple furnace bodies 2 along a first direction, thereby causing the mobile trolley 1 to drive the first limit switch 11 and the first trigger 12 to slide along the first direction, thereby causing the first trigger 12 to collide with the second limit switch 24 on different furnace bodies 2, and causing the first limit switch 11 to collide with the second trigger 3 on the outside of different furnace bodies 2.

[0036] Along the second direction, a first limit switch 11 and a first trigger 12 are fixedly installed on the side wall of the moving trolley 1 facing the furnace body 2, and the first trigger 12 is located above the first limit switch 11.

[0037] Along the second direction, a second limit switch 24 is fixedly installed on the side wall of each furnace body 2 facing the moving trolley 1.

[0038] Furthermore, along the first direction, each second limit switch 24 is provided with a second trigger 3 on both sides at intervals, and the second limit switch 24 is located directly above the second trigger 3.

[0039] like Figure 1 As shown, when the mobile trolley 1 slides from left to right along the first direction (from furnace body 21 to furnace body 23 along the first direction), the first limit switch 11 on the mobile trolley 1 collides with the second trigger 3 located to the left of the second limit switch 24 on furnace body 21. The first limit switch 11 is triggered and sends a deceleration signal, and the mobile trolley 1 begins to decelerate. Subsequently, the first trigger 12 collides with the second limit switch 24 located on furnace body 21, and the second limit switch 24 is triggered and sends a stop signal, and the mobile trolley 1 stops. After the mobile trolley 1 stops for a preset time, the mobile trolley 1 continues to slide to the right. The second trigger 3 located to the right of the second limit switch 24 on furnace body 21 does not trigger the first limit switch 11 on the mobile trolley 1, and the mobile trolley 1 moves towards... As furnace body 22 slides, the first limit switch 11 on the moving trolley 1 collides with the second trigger 3 located to the left of the second limit switch 24 on furnace body 22. The first limit switch 11 is triggered and sends a deceleration signal, and the moving trolley 1 begins to decelerate. Subsequently, the first trigger 12 collides with the second limit switch 24 located on furnace body 22, and the second limit switch 24 is triggered and sends a stop signal, causing the moving trolley 1 to stop. After a preset time, the moving trolley 1 continues to slide to the right. The second trigger 3 located to the right of the second limit switch 24 on furnace body 22 does not trigger the first limit switch 11 on the moving trolley 1, and the moving trolley 1 slides toward furnace body 23. The moving trolley 1 slides from furnace body 21 to furnace body 2N according to the above workflow, where N≥2.

[0040] When the mobile trolley 1 moves from left to right along the first direction, the second trigger 3 located to the left of the second limit switch 24 of any furnace body 2 triggers the first limit switch 11 on the mobile trolley 1, while the second trigger 3 located to the right of the second limit switch 24 of any furnace body 2 does not trigger the first limit switch 11 on the mobile trolley 1.

[0041] When the mobile trolley 1 moves from right to left along the first direction (from furnace body 23 to furnace body 21 along the first direction), the second trigger 3 located to the left of the second limit switch 24 of any furnace body 2 does not trigger the first limit switch 11 on the mobile trolley 1, while the second trigger 3 located to the right of the second limit switch 24 of any furnace body 2 triggers the first limit switch 11 on the mobile trolley 1.

[0042] Along the first direction, each second limit switch 24 is provided with a second trigger 3 on both sides, so that the second limit switch 24 can collide with the appropriate second trigger 3 during the process of sliding from left to right and from right to left, so as to decelerate the moving car 1.

[0043] Since the first trigger 12 is located above the first limit switch 11 and the second limit switch 24 is located above the second trigger 3, it can prevent the first trigger 12 from colliding and interfering with the first limit switch 11, and the second trigger 3 from colliding and interfering with the second limit switch 24.

[0044] Both the first and second directions are set horizontally, and the first direction is as follows: Figure 1 The direction indicated by the middle arrow ab, the second direction is as follows Figure 1 The direction indicated by the middle arrow cd.

[0045] The first trigger element 12 can be block-shaped or rod-shaped, etc.

[0046] The heat treatment production line provided in this embodiment only has one second limit switch 24 on each furnace body 2 and one first limit switch 11 on the moving trolley 1, which can reduce the number of limit switches used, thereby reducing costs and the failure rate of the heat treatment production line.

[0047] Furthermore, the first trigger 12 is rod-shaped, and the axis of the first trigger 12 is set along the second direction.

[0048] The rod-shaped first trigger 12 can accurately trigger the second limit switch 24.

[0049] Furthermore, the second trigger element 3 is block-shaped.

[0050] The second trigger 3 is block-shaped, which makes the second trigger 3 occupy a small volume and facilitates its placement.

[0051] The second trigger 3 can be fixedly installed on the side wall of the furnace body 2 facing the moving trolley 1 by the connector, or it can be fixedly installed on the ground by the positioning structure 4.

[0054] Along the second direction, each furnace body 2 has a positioning structure 4 on the ground on the side facing the moving trolley 1. Each positioning structure 4 is located between the moving trolley 1 and the furnace body 2. Each positioning structure 4 is spaced apart from its corresponding furnace body 2, the moving trolley 1, and the sliding track 5. The positioning structure 4 is located below the first trigger 12, which can prevent the positioning structure 4 from interfering with the first trigger 12.

[0057] The first mounting plate 42 and the second mounting plate 43 are respectively fixedly connected to the top of the base 41. The first mounting plate 42 and the second mounting plate 43 are connected to each other. The first mounting plate 42 and the second mounting plate 43 are inclined and symmetrically arranged, so that the first mounting plate 42 and the second mounting plate 43 form a V-shaped structure.
