Abstract
The utility model provides a sublevel caving coal hydraulic support frame tail beam, which comprises a tail beam and an insertion plate, wherein a crushing device capable of driving the insertion plate to upwards and downwards move is arranged in the middle of the tail beam and at the lower part of the insertion plate, the tail beam is connected with the crushing device, a connecting rod extends from the upper end of the crushing device, and the upper end of the connecting rod is connected with the insertion plate. The two side ends of the lower parts of the crushing device are fixedly arranged on the tail beam through pins. The inner middle part of the insertion plate is provided with a connecting lug with a downward opening, and the upper end of the connecting rod is fixedly arranged on the connecting lug arranged on the insertion plate through a pin shaft. When the sublevel caving coal hydraulic support frame tail beam is used, the pulse motive power output through the crushing device is transmitted to the insertion plate, the insertion plate can provide the pulse type action force for large-sized coal or hard coal, and the coal output of the sublevel caving coal hydraulic support frame is convenient. The sublevel caving coal hydraulic support frame tail beam has the advantages that the operation is convenient and fast, the motive power is reliable, and the pulse motive power can be provided for coal output.
Description
Technical field
The utility model relates to the caving roof coal hydraulic support technical field, is that a kind of being applicable under the big situation of top coal hardness put coal, the caving roof coal hydraulic support tail boom strong to the breaking capacity of coarse coal.
Background technology
The super high seam fully mechanized caving coal at the trial because coal body is hard, the joint fissure agensis; Top coal fracture lumpiness is big, can not be broken voluntarily, and cause top-coal recovery rate lower; Coal Loss is serious, and the fragile coal plate of putting of bulk top coal, has directly influenced work plane output and efficient.At this moment, common way is that comprehensive extracting and caving face need carry out the preparatory explosion of deep hole.The work plane explosion is prone to accidents on the one hand, very easily people and equipment is damaged, and also destroys the ore deposit, rock stratum on the other hand easily and presses stable.
Strengthen caving roof coal hydraulic support tail beam flashboard breaking capacity and play important effect putting coal.Existing plate generally links to each other with oil cylinder.Oil cylinder act as static extruding, and the bulk hard coal more is prone to fragmentation under the effect of dynamic force.Therefore be badly in need of the plate mechanism that development has dynamic force.
The utility model content
The purpose of the utility model is providing the caving roof coal hydraulic support tail boom that a kind of simple operation, power are reliable, pulsed power can be provided.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of caving roof coal hydraulic support tail boom; It includes tail boom, plate, is provided with the destroyer that the drive plate moves up and down at the middle part of tail boom and the bottom of plate, and this tail boom is connected with destroyer; This destroyer upper end is extended with connecting rod, and the upper end of this connecting rod is connected with plate.
Described destroyer bottom two side ends is fixed on the tail boom through pin.
The middle part is provided with the engaging lug under shed in the described plate, and the upper end of described connecting rod is fixed on the engaging lug on the plate through bearing pin.
During use, give plate through the pulsed transmission of power of destroyer output, plate provides a pulsed active force can for coarse coal or hard coal, is convenient to caving roof coal hydraulic support and puts coal.
The utility model has the advantages that: simple operation, power be reliable, can provide pulsed power to put coal.

The specific embodiment
A kind of caving roof coal hydraulic support tail boom; It includes tail boom 1, plate 5, is provided with the destroyer 2 that drive plate 5 moves up and down at the middle part of tail boom 1 and the bottom of plate 5, and this tail boom 1 is connected with destroyer 2; These destroyer 2 upper ends are extended with connecting rod 4, and the upper end of this connecting rod is connected with plate 5.
Described destroyer 2 bottom two side ends are fixed on the tail boom 1 through pin 3.
The middle part is provided with the engaging lug 6 under shed in the described plate 5, and the upper end of described connecting rod 4 is fixed on the engaging lug 6 on the plate 5 through bearing pin 8.
Destroyer 2 is installed in the tail boom 1 of caving roof coal hydraulic support, is welded with fixed block 9 on the tail boom 1, destroyer is fixed on the tail boom through pin 3.On plate, be provided with engaging lug 6, connecting rod 4 is installed on the plate through bearing pin 8, and through cottor pin 7 fixed pin shaft positions.The connecting rod other end is installed in the destroyer 2.Like this, just destroyer 2 and plate 5 are linked together through connecting rod 4.Start destroyer 4 through the operation hydraulic valve, the connecting rod of destroyer 4 can provide the operation power of pulsed for plate 5, can increase substantially the breaking capacity of Caving Coal tail beam flashboard to coal.
It more than is the preferred embodiment of the utility model and graphic; Above-mentioned preferred embodiment and graphic only illustrates; It is not the interest field that is used to limit the utility model; All with equalization technological means or be that the interest field that the application's claim is contained is implemented, all do not break away from the protection domain of the utility model.
