Abstract
The utility model is a mine-used non-symmetric connection central groove, which comprises an upper shovel plate groove, a cable trough stand plate, and a dumbbell-pin connection block. The two ends of the upper shovel plate groove are both fixed with the dumbbell-pin connection block. The utility model is characterized in that the two ends of the cable trough stand plate are fixed with the dumbbell-pin connection block. The utility model changes the dumbbell-pin connection block from the position of the two ends of the upper shield groove to the position of the two ends of the cable trough stand plate, then when central groove height is compressed, the dimension of dumbbell-pin connection block need not to be reduced, thus the strength of dumbbell-pin connection block is guaranteed, the accidents caused by the damages of the dumbbell-pin and dumbbell-pin connection block are effectively avoided. At the same time, the installation and disassembly of the dumbbell-pin are more convenient. The utility model has a positive popularization value in thin coal seam mining application.
Description
Technical field:
The utility model relates to a kind of intermediate channel of mine flight conveyer, the asymmetric intermediate channel in bonded assembly dumbbell pin position between particularly a kind of intermediate channel.
Background technology:
Intermediate channel generally is made of parts such as shovel board ledge, baffle plate ledge, cable ledge, middle plate and dumbbell pin Connection Blocks, shovel board ledge and baffle plate ledge link together after welding by middle plate, two ends of shovel board ledge and baffle plate ledge all are connected with the dumbbell pin Connection Block, this kind structure design of dumbbell pin Connection Block is called and is symmetrical arranged; Intermediate channel snaps in the dumbbell pin Connection Block with being connected of intermediate channel by dumbbell pin and is accomplished, and this connection mode is called symmetrical expression bonded assembly intermediate channel.
At present, exploiting girdle with low seam mining machinery is a kind of method commonly used both at home and abroad, and the gordian technique of low seam mining machinery exploitation is to reduce the height of coalcutter fuselage height and The middle pan of scraper conveyor.The way that compression intermediate channel height adopts usually is the size that reduces the dumbbell pin Connection Block of baffle plate ledge two ends, also reduced simultaneously the size of the dumbbell pin that is mated, the direct result that this method causes is to have reduced Joint strenght, the dumbbell pin easy fracture of size reduction, dumbbell pin Connection Block easily are torn in the pushing and sliding and the process of trying to stop people from fighting each other, thereby cause intermediate channel to be scrapped, have a strong impact on the ordinary production of underground coal exploitation.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, thereby a kind of size that can guarantee the dumbbell pin Connection Block when compression intermediate channel height of design guarantees the mining asymmetric bonded assembly intermediate channel of its intensity.
The realization the technical solution of the utility model is, a kind of mining asymmetric bonded assembly intermediate channel comprises shovel board ledge, cable duct riser and dumbbell pin Connection Block, and two ends of shovel board ledge all are connected with the dumbbell pin Connection Block, it is characterized in that two ends of cable duct riser are connected with the dumbbell pin Connection Block.
The dumbbell pin Connection Block that the utility model will be arranged on baffle plate ledge two ends originally changes two ends that are arranged on the cable duct riser into, become asymmetric bonded assembly intermediate channel, at this moment, when compression intermediate channel height, there is enough big space that the dumbbell pin Connection Block is set, and need not reduce the size of dumbbell pin Connection Block, thus guaranteed the intensity of dumbbell pin Connection Block, effectively avoid damaging the accident that the intermediate channel that causes is damaged because of dumbbell pin, dumbbell pin Connection Block.Non-symmetrical connection mode has also been avoided the position of shearer haulage pin row seat, the intermediate channel Joint strenght is improved, can reach every functional requirement that symmetrical expression connects intermediate channel fully, installation, the dismounting of while dumbbell pin are more convenient, when thin seam mining and other special exploitation mode, asymmetric bonded assembly intermediate channel has positive promotional value.
Description of drawings:
Fig. 1 is a structural representation block diagram of the present utility model.
Number in the figure: 1 shovel board ledge, 2 baffle plate ledges, 3 closure plates, 4 dumbbell pin Connection Blocks, 5 cable duct risers.
The specific embodiment:
The utility model is described in more detail below in conjunction with accompanying drawing.The dumbbell pin Connection Block 4 of cable duct riser 5 two end settings all is welded on the side near baffle plate ledge 2, and for ease of the connection of dumbbell pin, a side of above-mentioned dumbbell pin Connection Block 4 is provided with closure plate 3.
Claims (2)
1, a kind of mining asymmetric bonded assembly intermediate channel, comprise shovel board ledge (1), cable duct riser (5) and dumbbell pin Connection Block (4), two ends of shovel board ledge (1) all are connected with dumbbell pin Connection Block (4), it is characterized in that, two ends of cable duct riser (5) are connected with dumbbell pin Connection Block (4).
2, mining asymmetric bonded assembly intermediate channel according to claim 1, it is characterized in that, the dumbbell pin Connection Block (4) that described cable duct riser (5) two ends are provided with all is welded on the side near baffle plate ledge (2), and a side of above-mentioned dumbbell pin Connection Block (4) is provided with closure plate (3).
