[0050] The auxiliary damping system of the traction machine of the present application will be described in detail below through the following embodiments.

[0051] Embodiment one:

[0052] As shown in Figure 1 , the traction machine 100 is adopted for the current bottom damping mode, and there is a certain limitation problem, the embodiment proposes an auxiliary damping system of the traction machine 100, which comprises: a damping assembly 1, which is arranged at the top of the traction machine 100 and provides damping for the top of the traction machine 100. After the installation of the traction machine 100 is completed, the damping of the top of the traction machine 100 is further improved, thereby reducing the noise.

[0053] It should be noted that the traction machine 100 can be installed at the bottom first, and then the damping mechanism is installed, and then the auxiliary damping system is used to realize the double damping of the traction machine 100; or the damping mechanism is not installed during installation, and only the damping mechanism arranged above is used to realize the damping.

[0054] It should be noted that the top of the damping assembly 1 is installed on the roof plate of the machine room, or is installed on the mounting frame 3 for mounting the traction machine 100 through the support frame 2.

[0055] Embodiment two:

[0056] The embodiment is a further improvement based on the embodiment one.

[0057] As shown in Figures 1-8As shown in the embodiment, the damping assembly 1 comprises a damping part 11 made of elastic material, a first housing 12 having a mounting cavity in which the damping part 11 is arranged, a second housing 13 arranged on one side of the mounting cavity of the first housing 12 and capable of approaching or moving away from the first housing 12, and a connecting part 14 connecting the first housing 12 and the second housing 13 and allowing two ends of the damping part 11 to abut against the first housing 12 and the second housing 13 respectively.

[0058] The first housing 12 is arranged on the traction machine 100, and the second housing 13 is connected with an external object, or the first housing 12 is connected with an external object, and the second housing 13 is arranged on the traction machine 100.

[0059] When the traction machine 100 operates, external force generated by vibration of the traction machine 100 acts on the damping part 11 through the first housing 12 or the second housing 13 and is completely or partially absorbed by the damping part 11.

[0060] The damping assembly 1 mainly comprises the damping part 11, the first housing 12, the second housing 13 and the connecting part 14. The first housing 12 and the second housing 13 are arranged on the traction machine 100 and an external object (a roof plate or a mounting frame 3) respectively. When the traction machine 100 operates, external force generated by vibration of the traction machine 100 acts on the damping part 11, and the damping part 11 absorbs the external force, thereby reducing the vibration amplitude of the traction machine 100.

[0061] In the embodiment, the connecting part 14 comprises a first connecting piece 141 having a first mounting groove formed by bending the middle part and arranged on the first housing 12, and a second connecting piece 142 having a second mounting groove formed by bending the middle part and arranged on the second housing 13. The second connecting piece 142 and the first connecting piece 141 are arranged in a cross shape, and the second mounting groove is opposite to the first mounting groove.

[0062] The damping part 11 is arranged in a cavity formed by the first mounting groove and the second mounting groove.

[0063] To facilitate processing and mounting, the first connecting piece 141 and the second connecting piece 142 are sheet metal parts. The middle parts of the two long plate bodies are punched to form recesses, and then the bent plate bodies are cross-mounted. During the cross-mounting, the damping part 11 is arranged between the two plate bodies, and then the two plate bodies are fixed on the first housing 12 and the second housing 13 respectively.

[0064] It should be noted that the first shell 12 and the second shell 13 are also sheet metal structures. Specifically, a square plate body is stamped to form a square groove structure, and then two sides are also stamped to form mounting plates to form the first shell 12. The second shell 13 is stamped from a long plate body.

[0065] It should be noted that the damping part 11 can be made of rubber material.

[0066] Example Three:

[0067] This embodiment is a further improvement based on Example Two.

[0068] As shown in Figure 2 , Figure 6 In this embodiment, the damping assembly 1 further includes a pre-pressing locking part located in the mounting chamber for pre-pressing and locking the damping part 11 to prevent the damping part 11 from loosening.

[0069] Specifically, the pre-pressing locking part includes a pressing member 151, one end of which is arranged at the end of the first connecting member 141 and the other end of which is arranged on the second shell 13, for adjusting the height of the chamber formed by the first mounting groove and the second mounting groove to adjust the pre-tightening pressure of the damping part 11.

[0070] By setting the pre-pressing locking part, the pre-tightening purpose of the damping part 11 is achieved. After the damping part 11 is installed, according to actual needs, the pre-pressing locking part is adjusted to pre-tighten the damping part 11, and the maximum deformation of the pre-tightened damping part 11 is smaller, thereby reducing the failure accidents caused by the large deformation of the damping part 11. Moreover, after pre-tightening, the structure of the entire damping assembly 1 is more compact and less likely to loosen.

[0071] In this embodiment, the pre-pressing locking part further includes a connecting plate arranged at the side end of the second shell 13 and a pressing block 153 made of elastic material.

[0072] The pressing member 151 is arranged at one end of the connecting plate and connected to the pressing block 153 after passing through the connecting plate, so that the pressing block 153 abuts against the end of the first connecting member 141.

[0073] By setting the connecting plate, one end of the pressing member 151 is located on the outside, which is convenient for adjustment and installation. Specifically, the connecting plate is divided into a first plate body 1521 and a second plate body 1522, the first plate body 1521 is installed on the second shell 13, and both ends thereof extend from the second shell 13, and the second plate body 1522 is installed on one of the extending ends of the first plate body 1521. The pressing member 151 is threadedly connected with the second plate body 1522, and after the pressing member 151 passes through the second plate body 1522, the pressing member 151 is connected with the pressing block 153. By rotating the pressing member 151, the pressing member 151 gradually moves inward, and the other end thereof gradually applies pressure to the pressing block 153, so that the pressing block 153 is extruded, and the extrusion causes the first connecting member 141 to be extruded, so that the first connecting member 141 moves towards the second connecting member 142, thereby extruding the damping part 11.

[0074] It should be noted that the pre-pressing locking part 15 has two groups and is symmetrically arranged on both sides of the damping part 11 to provide stable pre-tightening force for the damping part 11.

[0075] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical application or improvement of the technology in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
