It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] like Figure 1-4 As shown, the utility model proposes a mainframe frame wire rope protective cover, comprising a protective cover shell 1, a heat dissipation through hole 8 is opened on the surface of the protective cover shell 1, and a sound insulation cotton 6 is pasted on the inner wall surface of the protective cover shell 1;

[0027] The inner wall surface of the protective cover shell 1 is equidistantly provided with a plurality of groups of bearing seats 9, the bearing seats 9 are of a double-row structure, the surfaces of the bearing seats 9 are rotatably connected with guide rollers 10, the ends of the guide rollers 10 are connected to the end support frames 11, and the bottom of the end support frames 11 is welded to the bottom of the inner cavity of the protective cover shell 1;

[0028] A threading groove 12 is formed through the bottom surface of the protective cover shell 1 , and the threading groove 12 is located between the two groups of guide rollers 10 .

[0029] It should be noted that the sound insulation cotton 6 can absorb the noise generated when the host device is working to reduce the noise diffusion and improve the quietness of the host device during operation. The corresponding through holes 7 on the surface of the sound insulation cotton 6 correspond to the heat dissipation through holes 8. The heat in the protective cover shell 1 can be dissipated through the heat dissipation through holes 8 to ensure the heat dissipation effect of the host device. The wire rope passes between the two sets of guide rollers 10 and then passes through the threading groove 12. The guide rollers 10 and the conductor rollers 13 can guide the wire rope. At the same time, the guide rollers 10 are used to limit the position to prevent the wire rope from swinging and rubbing against the inner wall of the protective cover shell 1 during movement, thereby improving the protection of the protective cover shell 1.

[0030] In this embodiment, if Figure 1 As shown, the top of the protective cover shell 1 is an arc-shaped structure, the bottom of the protective cover shell 1 is a triangular structure, and an air avoidance groove 2 is opened on the top of the protective cover shell 1. The air avoidance groove 2 is located in the middle of the arc-shaped structure on the top of the protective cover shell 1.

[0031] It should be noted that the top of the protective cover shell 1 is an arc-shaped structure, and a space avoidance groove 2 is opened in the middle of the arc-shaped structure. The bottom of the protective cover shell 1 is a triangular structure, which can make the protective cover shell 1 more closely fit the shape of the host device during installation.

[0032] In this embodiment, if Figure 2 and Figure 3 As shown, a contact seat 3 is welded at the edge of the open end surface of the protective cover shell 1, the width of the contact seat 3 is greater than the wall thickness of the protective cover shell 1, a rubber shock-absorbing pad 5 is provided on the surface of the contact seat 3, and a fixing frame 4 is welded on the surface of the contact seat 3, and the fixing frames 4 are symmetrically distributed on both sides of the protective cover shell 1.

[0033] It should be noted that the protective cover shell 1 contacts the surface of the host device through the contact seat 3. The width of the contact seat 3 is greater than the wall thickness of the protective cover shell 1, thereby increasing the contact area between the protective cover shell 1 and the surface of the host device and improving the stability of the installation of the protective cover shell 1. The surface of the contact seat 3 is provided with a rubber shock-absorbing pad 5, which can absorb the vibration generated when the host device is working, so as to reduce the vibration transmitted to the protective cover shell 1, avoid the loosening of the fixing bolts, and improve the stability of the installation of the protective cover shell 1.

[0034] In this embodiment, if Figure 2 and Figure 3 As shown, corresponding through holes 7 are opened on the surface of the sound insulation cotton 6, and the corresponding through holes 7 correspond to the heat dissipation through holes 8.

[0035] It should be noted that the corresponding through holes 7 and the heat dissipation through holes 8 can dissipate heat in a timely manner.

[0036] In this embodiment, if Figure 1 As shown, the inner cavity of the threading groove 12 is symmetrically provided with a wire roller 13, and the end of the wire roller 13 is rotatably connected to the inner wall of the threading groove 12.

[0037] It should be noted that the conductor roller 13 can guide the steel wire rope.

[0038] The working principle and use process of the utility model are as follows: the protective cover shell 1 is fixed by a fixing frame 4 and a fixing bolt. The top of the protective cover shell 1 is an arc-shaped structure, and an air avoidance groove 2 is opened in the middle of the arc-shaped structure. The bottom of the protective cover shell 1 is a triangular structure, which can make the protective cover shell 1 more closely fit the shape of the host device during installation. At the same time, the protective cover shell 1 contacts the surface of the host device through the contact seat 3. The width of the contact seat 3 is greater than the wall thickness of the protective cover shell 1, thereby increasing the contact area between the protective cover shell 1 and the surface of the host device and improving the stability of the installation of the protective cover shell 1. A rubber shock-absorbing pad 5 is provided on the surface of the contact seat 3. The rubber shock-absorbing pad 5 can absorb the vibration generated by the host device when it is working, so as to reduce the vibration transmitted to the protective cover shell 1 , avoid loosening of the fixing bolts, and improve the stability of the installation of the protective cover shell 1. The sound insulation cotton 6 can absorb the noise generated by the main device when it is working to reduce the noise diffusion and improve the quietness of the host device when it is running. The corresponding through holes 7 on the surface of the sound insulation cotton 6 correspond to the heat dissipation through holes 8. The heat in the protective cover shell 1 can be dissipated through the heat dissipation through holes 8 to ensure the heat dissipation effect of the host device. The wire rope passes between the two sets of guide rollers 10 and then passes through the threading groove 12. The guide roller 10 and the conductor roller 13 can guide the wire rope. At the same time, the guide roller 10 is used to limit the position to avoid the wire rope from swinging during movement and rubbing against the inner wall of the protective cover shell 1, which can improve the protection of the protective cover shell 1.
