Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and in particular to a step-type clamp heat treatment equipment. Background Technology

[0002] Rail joints are an important railway component used for connecting rails. The release of internal stress in the rail joints directly affects the final product quality; therefore, heat treatment is particularly important for product stability. Currently, the main technical route for rail joint heat treatment in China is as follows: multiple rail joints are stacked together, and using a gantry crane, the stacked rail joints are placed as a whole into a pit furnace or other type of electric heating furnace. After heating and holding at a certain temperature for a period of time, they are lifted out as a whole and placed in a quenching medium for quenching. After the rail joints cool, they are placed in a pre-set temperature holding chamber for tempering.

[0003] When removing or placing clamping plates in a heating furnace, especially in the high-temperature furnace cavity or after the clamping plates have been heated, the limited space within the furnace cavity hinders workers' ability to operate the overhead crane to do so. This results in inefficient and cumbersome operation. Therefore, there is an urgent need for a heat treatment device that can automatically move clamping plates in and out. Utility Model Content

[0004] The purpose of this utility model is to provide a walking plate heat treatment device to solve the problems of poor operation, low efficiency, and extremely troublesome and dangerous operation when the heating furnace takes out or puts in the plates.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A walking beam heat treatment device includes a heating furnace body. A ring track is arranged through the furnace cavity of the heating furnace body. Multiple movable supports are evenly arranged and slidably installed on the ring track. The multiple movable supports are connected by a chain. Multiple sprockets are arranged on the inner side of the chain and mesh with it. One of the sprockets is connected to the power output end of a motor.

[0007] A further technical solution is that multiple protrusions are provided on the top of the movable bracket.

[0008] A further technical solution is that a pressure rod is installed on the top of the movable bracket via a torsion spring.

[0009] A further technical solution is that the top of the movable bracket is provided with a recessed portion, and the pressure rod is provided with an upper protrusion.

[0010] A further technical solution is that a heat-resistant folding structure is provided between the two sides of the movable support and the furnace cavity of the heating furnace body.

[0011] A further technical solution is that the folded heat-insulating structure consists of multiple heat-insulating plates and grooves that are adapted to the heat-insulating plates.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] This utility model proposes a step-type clamping plate heat treatment equipment. This heat treatment equipment can continuously heat clamping plates and achieve automatic feeding and unloading of clamping plates in the heating furnace. When heating the current clamping plate in the heating furnace, the clamping plate to be heated can be placed on an empty movable support in advance, and the heated clamping plate can be removed from the movable support that has just come out of the furnace. The operation is quick and improves work efficiency. Attached Figure Description

[0024] Example 1:

[0025] This implementation example Figure 1 and Figure 2 As shown, the heat treatment equipment for the type of clamp plate includes a heating furnace body 1. A ring track 2 is installed through the furnace cavity of the heating furnace body 1. Multiple movable supports 3 are evenly arranged and slidably installed on the ring track 2. The multiple movable supports 3 are connected by a chain 4. Multiple sprockets 5 are provided on the inner side of the chain 4 and mesh with it. One of the sprockets 5 is connected to the power output end of the motor 6.

[0026] First, place the clamping plate on the movable support 3. Then, the motor 6 drives the chain 4 to rotate, while moving the movable support 3 along the circular track 2 and through the furnace cavity of the heating furnace body 1. When the heating furnace body 1 is heating the current clamping plate, the clamping plate to be heated can be placed on the empty movable support 3 in advance. At the same time, the heated clamping plate can be removed from the movable support 3 after it has just come out of the furnace. The operation is quick and improves work efficiency.

[0027] Preferably, the top of the movable bracket 3 is provided with a plurality of protrusions 7.

[0028] The protrusion 7 can prevent the clamping plate from forming a closed surface with the top of the movable bracket 3, and the point contact can improve the heating efficiency and uniformity of the clamping plate.

[0029] Example 2:

[0030] Based on the above embodiments, this embodiment shows that a pressure rod 8 is mounted on the top of the movable bracket 3 via a torsion spring.

[0031] The pressure bar 8 can press the clamping plate onto the top of the movable bracket 3 to prevent the clamping plate from detaching from the movable bracket 3 due to the sudden start or stop of the motor 6.

[0032] Preferably, the top of the movable bracket 3 is provided with a recessed portion, and the pressure rod 8 is provided with an upper protrusion.

[0033] The top of the pressure bar 8 and the movable bracket 3 can form a clamping cavity for the clamping plate, which can increase the loading capacity and more stably clamp the clamping plate.

[0034] Preferably, such as Figure 3 As shown, a folded heat-insulating structure 9 is provided between the two sides of the movable support 3 and the furnace cavity of the heating furnace body 1. The folded heat-insulating structure 9 consists of multiple heat-insulating plates and grooves that are adapted to the heat-insulating plates.

[0035] When the heating plate is heated, the heat-insulating structure 9 can prevent heat from flowing out from the gap between the two sides of the movable support 3 and the heating furnace body 1, thereby improving the heat preservation effect and saving energy.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
