[0022] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0023] In the following description, a lot of specific details are set forth in order to facilitate a full understanding of the utility model, but the utility model can also be implemented in other ways different from the description herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] EMBODIMENT

[0026] REFERENCE Figs. 1-4 For the embodiment of the utility model, the embodiment provides a hanger for heat treatment production of mine pick, which comprises,

[0027] The bearing mechanism 100 comprises the horizontal plate 101, the channel 102 horizontally arranged on the top of the horizontal plate 101 and the slot 103 arranged on the outer side of the horizontal plate 101;

[0028] The hanging mechanism 200 comprises a top plate 201 placed on the top of the horizontal plate 101, a buffer assembly 202 arranged at the bottom of the top plate 201, and a support assembly 203 arranged at the bottom of the buffer assembly 202.

[0029] In the heat treatment process, when the hanging mechanism 200 needs to move in the heating furnace or is affected by thermal stress, the bearing mechanism 100 serves as a solid support structure to prevent the hanging mechanism 200 from deforming or collapsing. The top plate 201 of the hanging mechanism 200 provides a stable placement surface for the cutting pick, which can be optimized according to the shape of the cutting pick to ensure stable placement. The buffer assembly 202 can absorb vibrations during the heat treatment process, such as the impact of cooling liquid during quenching, to prevent the cutting picks from colliding with each other or being damaged due to vibrations. The support assembly 203 provides stable support for the hanging mechanism, and the components work together to disperse pressure, prevent components from falling off, and maintain structural stability.

[0030] Specifically, the hanging mechanism 200 further comprises a deep groove ball bearing 204 fixedly installed at the bottom of the horizontal plate 101, and a ball 205 adaptively installed at the bottom of the deep groove ball bearing 204. The buffer assembly 202 comprises a disc body 202a fixedly installed at the bottom of the horizontal plate 101, a ring 202b fixedly installed at the center of the inner cavity of the disc body 202a, a plurality of damping springs 202c fixedly installed on the outer surface of the ring 202b, a gasket 202d fixedly installed at the bottom of the ring 202b, and a threaded rod 202e fixedly installed at the center of the bottom of the ring 202b.

[0031] The deep groove ball bearing 204 and the ball 205 can effectively ensure the movement of the hanging mechanism 200, thereby ensuring the safe and stable heat treatment of the cutting pick. In the heat treatment process of the mining cutting pick, the hanger may be affected by various vibration sources, such as the impact of cooling liquid during quenching, the disturbance of airflow in the heating furnace, etc. The damping springs 202c can effectively absorb and buffer these vibrations to prevent the cutting picks from colliding with each other or the internal structure from being damaged due to vibrations. The ring 202b ensures that the force is transmitted to the damping springs 202c in the correct direction, so that the damping springs 202c can evenly disperse the pressure. The gasket 202d is fixed at the bottom of the ring 202b, which can prevent the bottom of the ring 202b from directly rubbing with other components, thereby protecting the components and prolonging the service life of the components. The threaded rod 202e is threadedly connected with the threaded seat 203a, which facilitates the overall disassembly of the support assembly 203.

[0032] Further, the support assembly 203 comprises a threaded seat 203a threadedly connected with the threaded rod 202e, a plurality of support rods 203b fixedly installed at the bottom of the threaded seat 203a, a support ring 203c fixedly installed at the bottom of the support rods 203b, an elastic retainer ring 203d fixedly installed at the bottom of the support ring 203c, and a positioning piece 203e provided at the inner surface of the elastic retainer ring 203d, the positioning piece 203e comprising a sleeve 203e-1 fixedly installed at the inner surface of the elastic retainer ring 203d, a limiting sleeve 203e-2 fixedly installed at the inner cavity of the sleeve 203e-1, a return spring 203e-3 fixedly installed at the inner cavity of the limiting sleeve 203e-2, an arc-shaped sleeve 203e-4 fixedly installed at the end of the return spring 203e-3, a clamping groove 203e-5 formed at the outer side of the limiting sleeve 203e-2, and an adjusting piece 203e-6 fixedly installed at the inner surface of the arc-shaped sleeve 203e-4, the adjusting piece 203e-6 being clamped with the clamping groove 203e-5, and the slot 103 being in communication with one side of the channel 102.

[0033] The support rods 203b can provide good support when the mining pick is heavy, the support ring 203c can evenly distribute the weight of the pick on the contact surface, reduce the local excessive pressure, improve the stability of the pick, the elastic retainer ring 203d can limit and protect the support assembly 203 from falling off when subjected to external force, and can also buffer the impact force from below to a certain extent, the limiting sleeve 203e-2 limits the movement range of the internal pick, the return spring 203e-3 can restore the pick to the original position after being deformed by external force, the clamping groove 203e-5 and the adjusting piece 203e-6 are clamped with each other to stabilize the position of the arc-shaped sleeve 203e-4, thereby ensuring the normal function of the support assembly 203 and maintaining the stability of the pick.

[0034] In use, the horizontal plate 101 provides a stable base platform for the entire hanger, which can bear the weight of other components on the hanger and the mining pick, and ensure the stability of the overall structure of the hanger during heat treatment, the hanging assembly 200 can be inserted into the channel 102 from the side, the channel 102 plays a guiding role when the hanging assembly 200 slides horizontally on the horizontal plate 101, ensuring the accuracy of component installation and the stability of movement, the buffer assembly 202 absorbs and buffers vibration through components such as the damping spring 202c, protecting the pick from damage, the support assembly 203 provides stable support through the support rods 203b and the support ring 203c, disperses pressure, prevents components from falling off, and maintains structural stability through the positioning piece 203e.

[0035] In summary, the hanging mechanism 200 provides a stable placement space for the cutting tooth, which can be optimized according to the shape of the cutting tooth to ensure stable placement, the buffer assembly 202 can absorb the vibration in the heat treatment process, can buffer the vibration generated by the impact of the cooling liquid during quenching, and avoid the mutual collision or damage of the cutting tooth due to vibration, the support assembly 203 provides stable support for the hanging mechanism, and the cooperation of each part disperses the pressure, prevents the parts from falling off, and maintains the structural stability.
