The utility model discloses a colliery is anchor pulling device in pit, it includes super front support hydraulic frame, it articulates on super front support hydraulic frame has first hydraulic cylinder, the piston rod top of first hydraulic cylinder articulates with the cylinder body of second hydraulic cylinder, the bottom of second hydraulic cylinder articulates with advance support hydraulic frame, the piston rod of second hydraulic cylinder is connected with the iron chain, the other end of iron chain is connected with the stock, first hydraulic cylinder and second hydraulic cylinder all are connected with the hydraulic oil pump through hydraulic oil pipeline, install the switching-over valve on the hydraulic oil pipeline; the utility model has the advantages that: the utility model discloses simple structure installs on advance support hydraulic pressure frame the utility model discloses a pull out anchor ware extracts the stock on will producing the coal group through pulling out the anchor ware, labour saving and time saving, effectual improvement production efficiency, the stock can be timely is extracted, and the effectual stock of having avoided gets into the coal flow system, avoids taking place the production accident and influences production, is worth using widely on a large scale.
Description
The technical field is as follows:
the utility model relates to an embedded part installation template technical field especially relates to a colliery is anchor ware pulled out in pit.
Background art:
in the production process of colliery underground working face, need the manual work to demolish the stock in advance, facilities such as stock tablet, anchor net waste time and energy, have the potential safety hazard again, and the stock that does not demolish most probably sneaks into the coal flow system and with the cargo airplane hyoplastron, influences the working face production, causes the production accident, and the urgent need is to design an automatic anchor pulling device and pulls out the anchor operation.
The utility model has the following contents:
an object of the utility model is to provide a colliery is anchor pulling device in pit.
The content of the utility model is as follows: the utility model provides a colliery is anchor pulling ware in pit, its includes super front support hydraulic frame it has first hydraulic cylinder to articulate on the super front support hydraulic frame, first hydraulic cylinder's piston rod top is articulated with the cylinder body of second hydraulic cylinder, the bottom of second hydraulic cylinder with advance support hydraulic frame is articulated, the piston rod of second hydraulic cylinder is connected with the iron chain, the other end of iron chain is connected with the stock, first hydraulic cylinder with the second hydraulic cylinder all is connected with hydraulic oil pump through hydraulic oil pipeline, install the switching-over valve on the hydraulic oil pipeline.
The utility model has the advantages that: the utility model discloses simple structure installs on advance support hydraulic pressure frame the utility model discloses a pull out anchor ware extracts the stock on will producing the coal group through pulling out the anchor ware, labour saving and time saving, effectual improvement production efficiency, the stock can be timely is extracted, and the effectual stock of having avoided gets into the coal flow system, avoids taking place the production accident and influences production, is worth using widely on a large scale.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
in the figure, an ultra-front support hydraulic frame 1, a first hydraulic oil cylinder 2, a second hydraulic oil cylinder 3 and an iron chain 4.
The specific implementation mode is as follows:
as shown in figure 1, the underground anchor puller for the coal mine comprises an ultra-front support hydraulic frame 1, wherein a first hydraulic oil cylinder 2 is hinged to the ultra-front support hydraulic frame 1, the top end of a piston rod of the first hydraulic oil cylinder 2 is hinged to a cylinder body of a second hydraulic oil cylinder 3, the bottom of the second hydraulic oil cylinder 3 is hinged to the ultra-front support hydraulic frame 1, a piston rod of the second hydraulic oil cylinder 3 is connected with an iron chain 4, the other end of the iron chain 4 is connected with an anchor rod, the first hydraulic oil cylinder 2 and the second hydraulic oil cylinder 3 are connected with a hydraulic oil pump through a hydraulic oil pipeline, and a reversing valve is installed on the hydraulic oil pipeline.
The working principle is as follows: during operation, the angle of the second hydraulic cylinder 3 is adjusted by adjusting the extension amount of the first hydraulic cylinder 2, when the angle of the second hydraulic cylinder 3 is consistent with the angle of the anchor rod to be pulled out, at the moment, the second hydraulic cylinder 3 is started to enable the piston rod of the second hydraulic cylinder 3 to extend out and connect the iron chain 4 with the anchor rod, and then the electromagnetic valve is operated to enable the piston rod of the second hydraulic cylinder 3 to retract to pull out the anchor rod.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
