Description

Technical Field

[0001] The utility model belongs to the field of machinery for mining working surfaces in lanes of coal mines and mines, and particularly relates to a support on the working surface. After the support is used, a support withdrawal and loading platform is required to withdraw the support. Background Art

[0002] In coal mines and roadway operations, many supports are typically used at the mining face. Large loading equipment is used to load the supports from outside onto rail-mounted flatbed trucks, bringing them in from the tracks. Unloading is not difficult. However, once the work on the face is completed, many supports need to be loaded onto trucks for transport, which is a challenging task. The supports are heavy, making it difficult to use the lifting equipment, making loading difficult. The working face is at the end of a roadway, at the end of the coal transport track, especially in roadways with small mining faces, where large, specialized machinery cannot be used. This makes it difficult to withdraw the supports, and there are also safety issues during loading and unloading. Summary of the Invention

[0027] The steps of using the utility model are as follows:

[0028] S1. Based on the overall roadway work surface schedule, 25-30 days before the removal of the gantry, cast a reinforced concrete loading platform 1 at the loading site near the track 18. Simultaneously, cast the support platform 14, groove 7, groove pinhole 81, and baffle 9 onto the loading platform 1 and anchor them with anchor bars 17.

[0029] S2. A pulley 19 is fixedly installed on the tunnel roof 15 at a distance of 20 to 30 meters from the loading platform in advance, and the raised rod 6 made of 6 mm thick steel plate is welded and fixed to the front end of the flatbed truck 2. The pin holes 82 at both ends of the raised rod 6 are made of 30 mm thick steel plate.

[0030] S3. The removal of the rack begins, and the flatbed trolley 2 is moved on the track 18 to approach the loading platform 1, and the flatbed trolley 2 is continued to be pushed. The raised rod 6 on the end of the flatbed trolley 2 is embedded in the groove 7 on the supporting platform 14, and the raised pin holes 82 at both ends of the raised rod 6 are respectively aligned with the two groove pin holes 81. At this time, two pins 16 are respectively inserted into the two groups of aligned pin holes to fix and lock the flatbed trolley 2 and the loading platform 1; at the same time, the end support plate 83 of the flatbed trolley 2 is also placed on the supporting platform 14 on the steep slope 12.

[0031] S4. The winch rope 13 pulls the bracket 3 through the pulley 19. The bracket 3 slides upward along the gentle slope 11 to the flatbed truck 2 under the limitation of the baffle 9. The bracket is fixed using the limiting hole 5, the winch rope 13 is released, and the two pins 16 are taken out of the pin holes.

[0032] S5. The winch rope 13 is removed from the pulley 19 and connected to the hook ring 10 to directly pull the flatbed truck 2 to transport the bracket 3.

[0033] The use of this rack removal and loading platform solves the problem of difficult rack removal. For heavy racks and narrow operating space environments, it can not only facilitate rack removal, but also ensure the safety of workers, reduce labor intensity, and improve work efficiency.
