Technical Field

[0001] The utility model relates to the technical field of transportation, in particular to a support transportation device used for gob-side lane retention in underground coal seams. Background Art

[0002] Gob-side entry retention refers to the maintenance of the original mining roadway along the edge of the goaf after the coal mining face. In order to recover the protective coal pillars left in traditional mining methods, certain technical means are used to re-support the drift of the previous section and leave it for use in the next section. This approach of leaving a roadway along the edge of the goaf at the original drift position is called gob-side entry retention. Gob-side entry retention can maximize resource recovery and avoid coal body loss. Among them, the most critical thing about gob-side entry retention is to study the mine pressure characteristics of the roof above the supporting isolation zone to determine the appropriate support form and support strength. Studying the mine pressure characteristics of the roadway roof to determine the appropriate initial support plan and support parameters for the drift.

It is more flexible to use and improves the overall transportation efficiency. By rotating the rotary column, the gear sleeve and the adjustment shaft are driven to rotate through the ring gear, and the upward side block is rotated to face the lower side, which can release one side of the U-shaped structure, and the support placed on the carrying piece can be quickly poured down, effectively realizing the rapid removal of the transfer support on the rail mine car, making the operation simpler and ensuring the overall construction efficiency.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-5 The utility model is described in further detail. Example 1

[0031] like Figures 1-4 As shown, in order to solve the existing problems, in this embodiment, the utility model discloses a support transfer equipment for underground coal seam along the goaf, including a chassis 1 and a roller 2 rotatably connected to its bottom, a rotating bracket 3 is connected to the top of the chassis 1, the rotating bracket 3 is rotatably connected to the rotating shaft 6, the rotating shaft 6 is connected to the truck bed 4, the top of the truck bed 4 is connected to the dividing component 5, the rotating shafts 6 are symmetrically distributed on both sides of the truck bed 4, the rotating shaft 6 is connected to the ratchet component 7, and the rotating shaft 6 on the other side is connected to the rotating component 8.

[0032] The dividing component 5 includes a clamping member 502 that contacts the top of the truck bucket 4. The clamping member 502 is L-shaped and is provided with a sliding groove 503. The inner wall of the sliding groove 503 is slidably connected to a locking member 501. The bottom of the locking member 501 is threadedly connected to a partition plate 504. The partition plate 504 is arranged inside the truck bucket 4.

[0033] The ratchet component 7 includes a ratchet 701 connected to the rotating shaft 6, the rotating bracket 3 is rotatably connected to a blocking member 702, a spring 705 is connected to the side of the blocking member 702, the other end of the spring 705 is connected to a spring bracket 704, the spring bracket 704 is connected to the rotating bracket 3, and a rotating handle 703 is connected to the side of the blocking member 702.

[0034] The rotating component 8 includes a driven gear 801 connected to the rotating shaft 6. The driven gear 801 is meshed with a driving gear 802. The driving gear 802 is rotatably connected to the side of the rotating bracket 3. The side of the driving gear 802 is connected to a control handle 803.

[0035] The specific working principle is: this device can effectively improve the handling efficiency of mine cars. Compared with traditional devices, this device can improve the handling efficiency of mine cars and speed up the discharge speed of the device.

[0036] When this device is in use, the clamping member 502 can slide freely by unlocking the locking member 501, and the spacing between the partition plates 504 can be adjusted. After the adjustment of the partition plates 504 is completed, the side of the clamping member 502 can be brought into contact and squeezed with the outer side of the truck bed 4 by sliding the clamping member 502. At this time, the partition plates 504 cannot shake, and rotating the locking member 501 can fix the current position of the partition plates 504.

During the rotation of the truck bed 4, the ratchet 701 on the other side rotates synchronously. At this time, the blocking member 702 repeatedly rotates elastically under the support of the spring 705. Due to the structural characteristics of the ratchet 701, it can only rotate in one direction under the blocking effect of the blocking member 702, so that no accidental reverse rotation will occur when driving the truck bed 4 to rotate tiltably.

[0038] After the bracket is dumped out from the interior of the bucket 4, the blocking member 702 is manually rotated by rotating the handle 703, thereby manually unlocking the blocking member 702 so that the bucket 4 can be rotated in the opposite direction to achieve a reset effect. Example 2
