Abstract
The utility model belongs to the specific purpose tool that dismounting mine mining bracket class connects bearing pin, particularly a kind of pin pulling tool of hydraulic jack control, comprise hydraulic jack, stay pipe by Flange joint at the head of hydraulic jack, on the tube wall at stay pipe two ends, horizontally set the perforate of through tube wall respectively, outer end in stay pipe arranges U-shaped connector, two parallel-plates of U-shaped connector arrange corresponding pin-and-hole respectively, the connecting bottom board of two parallel-plates arranges through hole, through hole coordinates bolt is installed.It is rational in infrastructure, easy to operate, can realize, to the dismantlement work of all kinds of connection bearing pin, replacing the work of artificial high strength, stable performance, be disassembled into power high with mechanization.
Description
Technical field
The utility model belongs to the specific purpose tool that dismounting mine mining bracket class connects bearing pin, the pin pulling tool of particularly a kind of hydraulic jack control.
Background technology
Along with social progress, the development of productivity, growing to the demand of resource, the minimizing of resource, and waste.The development in colliery also trends towards maximizing, and the mechanization degree that colliery uses is more and more higher, and medium-and-large-sized mine achieves mechanization comprehensive exploitation substantially, along with the oil cylinder, the jack that increase a large amount of use all size of down-hole support apparatus.Underground work bad environments toxic and harmful, corrosive liquid knows from experience badly damaged connection bearing pin, and big gun in coal mining process jumps, and partially helps, and splashes, and colliding with in inclined seam situation in Coal Transport process is waited all can damage connection bearing pin in various degree.The damage of bearing pin directly can cause very heavy normal work.
Utility model content
The purpose of this utility model is the pin pulling tool providing a kind of hydraulic jack to control, and it is rational in infrastructure, easy to operate, can realize, to the dismantlement work of all kinds of connection bearing pin, replacing the work of artificial high strength, stable performance, be disassembled into power high with mechanization.
The purpose of this utility model is achieved in that the pin pulling tool that a kind of hydraulic jack controls, comprise hydraulic jack, stay pipe by Flange joint at the head of hydraulic jack, on the tube wall at stay pipe two ends, horizontally set the perforate of through tube wall respectively, outer end in stay pipe arranges U-shaped connector, two parallel-plates of U-shaped connector arrange corresponding pin-and-hole respectively, the connecting bottom board of two parallel-plates arranges through hole, through hole coordinates bolt is installed.
The bolt of connector is connected with needing the pin shaft thread hole of dismantling by the utility model; The cylinder ends of hydraulic jack is welded and fixed a mounting flange, for being connected with the ring flange of stay pipe; Stay pipe is welded with ring flange; Be connected with the bolt of 6 M8 × 30 between stay pipe flange with hydraulic jack flange; After connecting each parts, connector is connected with hydraulic jack pusher rod connecting bolt.
The course of work of the present utility model is:
Hydraulic jack feed flow is suppressed, and promotes the piston rod retraction of hydraulic jack, pulls the bolt of connector and pinned connection, thus extract the bearing pin needing dismounting.
This equipment realizes the object to dismounting hinge pin by the pulling force of hydraulic jack.The dismantlement work to all size bearing pin can be realized by replacing connector, be applicable to the dismounting hinge pin of different size, be applicable to the dismounting hinge pin work of different damaged condition.By the advantageous use to hydraulic jack, solve artificial unloading's efficiency low, the shortcoming that labour intensity is large.
The utility model is rational in infrastructure, easy to operate, achieves the work to all kinds of connection dismounting hinge pin, and replace artificial unloading's work with mechanization, stable performance, dismantle effective, removal efficiency is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The pin pulling tool that a kind of hydraulic jack controls, as shown in Figure 1, comprise hydraulic jack 5, it is characterized in that: stay pipe 3 at the head of hydraulic jack 5 by Flange joint, on the tube wall at stay pipe 3 two ends, horizontally set the perforate 4 of through tube wall respectively, and the outer end in stay pipe 3 arranges U-shaped connector 2, and two parallel-plates of U-shaped connector 2 arrange corresponding pin-and-hole 6 respectively, the connecting bottom board of two parallel-plates arranges through hole, through hole coordinates bolt 1 is installed.Stay pipe 3 is by diameter 140 ㎜, and wall thickness is that the steel pipe of 5 ㎜ is formed.Hydraulic jack 1 is made up of the hydraulic jack of model 80/60-450.The size of perforate 4 on the tube wall of stay pipe 3 two ends is being advisable by dismounting latch easily.
Claims (4)
