[0029] Example: Figure 1-6As shown, this utility model provides a maintenance platform for a gyratory crusher. The maintenance platform includes a maintenance platform 1, a walking ladder 2, and a support member 3. The walking ladder 2 is located on one side of the maintenance platform 1, and the support member 3 is located below the maintenance platform 1. The walking ladder 2 is used for maintenance workers to walk onto the maintenance platform 1. The maintenance platform 1 is used for the maintenance of the frame pins, crossbeam pins, and crusher vibration inspection in the crusher body 20. The support member 3 is used to support the maintenance platform 1 and improve the stability of the maintenance platform 1.

[0030] The maintenance platform 1 includes I-beams 11, a platform plate 12, transverse reinforcing steel 15, and longitudinal reinforcing steel 16. Four I-beams 11 are provided, and several transverse and longitudinal reinforcing steel 15 and 16 are provided. The four I-beams 11 are fixed together by welding. The I-beams 11 are welded to the side wall of the mounting well 10 by anchor bolts. The transverse and longitudinal reinforcing steel 15 and 16 are welded and fixed inside the four I-beams 11. The platform plate 12 is fixedly installed on the upper surface of the four I-beams 11, and a [missing information - likely a design feature] is opened at the center of the platform plate 12. The crusher body 20 passes through the central hole 13. A reinforcing ring 14 is fixedly installed at the edge of the central hole 13. By installing the reinforcing ring 14, the stability at the position of the central hole 13 can be improved, and the platform plate 12 can be prevented from cracking. A maintenance toolbox 17 is fixedly installed on the upper surface of the platform plate 12. By installing the maintenance toolbox 17, the maintenance tools and consumables required for the frame pins, crossbeam pins, and crusher vibration inspection in the crusher body 20 can be stored in the maintenance toolbox 17.

[0031] The staircase 2 includes channel steel steps 21 and guardrails 22. The channel steel steps 21 are welded and fixed to one side of the I-shaped steel 11. The guardrails 22 are L-shaped and are welded and fixed to the channel steel steps 21 and the I-shaped steel 11. By setting the channel steel steps 21 and guardrails 22, the channel steel steps 21 facilitate maintenance workers to walk onto the platform 12. The guardrails 22 can protect the edges of the platform 12 and the edges of the channel steel steps 21, improve stability, and prevent maintenance workers from falling during maintenance.

[0032] Support component 3 includes a bottom support column 31, a top support column 32, a U-shaped sleeve plate 33, and a support base plate 35. Four support columns 31, 32, 33, and 35 are provided. These support columns support the inspection platform 1, improving its stability and preventing it from wobbling. One end of the bottom support column 31 and... The upper surface of the supporting base plate 35 is fixedly connected, and the top supporting column 32 is slidably disposed within the bottom supporting column 31. One end of the top supporting column 32 is fixedly connected to the lower surface of the U-shaped sleeve plate 33. The longitudinal reinforcing steel 16 is movably engaged within the U-shaped sleeve plate 33. An anti-slip pad 34 is fixedly disposed on the inner wall of the U-shaped sleeve plate 33. The outer wall of the longitudinal reinforcing steel 16 and the inner wall of the anti-slip pad 34 are in movable contact. By providing the anti-slip pad 34, the stability between the U-shaped sleeve plate 33 and the longitudinal reinforcing steel 16 is improved, thus supporting the base plate 35. An anti-slip pad 36 is fixedly installed on the lower surface. By installing the anti-slip pad 36, during the assembly of the support member 3 into the mounting well 10, the lower surface of the anti-slip pad 36 contacts the bottom wall of the mounting well 10, thereby improving the stability of the support base plate 35. Several assembly holes 37 are provided on the support base plate 35. Through the installation of the assembly holes 37 and the action of the assembly bolts, the support base plate 35 can be fixed to the bottom of the mounting well 10. A limit bolt 38 is threadedly installed on the end of the bottom support column 31 away from the support base plate 35. Several threaded holes 39 are provided on both sides of the top support column 32. The limiting bolt 38 passes through the threaded hole 39 and is rotatably connected to the inner wall of the threaded hole 39. By setting the limiting bolt 38 and multiple threaded holes 39, the top support column 32 can be slid in the bottom support column 31 before the support component 3 is assembled, and the overall length of the support component 3 can be adjusted to suit the distance between the inspection platform 1 and the bottom wall of the installation well 10. When the thread of the limiting bolt 38 enters the interior of the corresponding threaded hole 39, the top support column 32 can be limited and fixed.

[0033] Working principle: When it is necessary to inspect and repair the crusher body 20 installed in the installation well 10, the operators first build an inspection platform using four I-beams 11, a platform plate 12, multiple transverse reinforcing steels 15, multiple longitudinal reinforcing steels 16, channel steel steps 21, and guardrails 22. The four I-beams 11 are fixed to the side wall of the installation well 10 by anchor welding. The multiple transverse reinforcing steels 15 and multiple longitudinal reinforcing steels 16 are welded and fixed inside the four I-beams 11. The channel steel steps 21 are welded to one side of the I-beams 11. The guardrails 22 are welded and fixed to the channel steel steps 21 and the I-beams 11. Then, a central hole 13 is dug in the center of the platform plate 12, and the platform plate 12 is fixed to the four I-beams 11. The reinforcing ring 14 is fixed to the edge of the central hole 13. At this time, the inspection platform is initially formed, and the bottom of the crusher body 20 passes through the central hole 13.

[0034] Subsequently, pull the top support column 32 to slide it inside the bottom support column 31, adjust the overall length of the support component 3, and then make the U-shaped sleeve 33 fit under the longitudinal reinforcing steel 16. Then, pass the limiting bolt 38 through the corresponding threaded hole 39 to fix the top support column 32. At the same time, fix the support base plate 35 to the bottom wall of the installation well 10 through the assembly hole 37 and the assembly bolt. At this time, the support base plate 35, the bottom support column 31, the top support column 32 and the U-shaped sleeve 33 support the maintenance platform 1, improve its stability and avoid shaking.

[0035] During subsequent maintenance, maintenance workers can walk up to the platform plate 12 via the channel steel steps 21 to inspect the central frame pin, crossbeam pin, and crusher vibration at the bottom of the crusher body 20, thereby improving the convenience of daily maintenance of the crusher body 20 and enhancing the safety of maintenance workers.
