Abstract
A pin puller comprises a hydraulic bracket, wherein the hydraulic bracket is provided with a pin pulling hydraulic cylinder, an ejection cylinder is arranged on the pin pulling hydraulic cylinder at the end of a piston rod, an ejection pin device is connected with the piston rod and penetrates through the ejection cylinder; the hydraulic bracket comprises an upper platform and a lower platform; a lifting frame is arranged between the upper platform and the lower platform and driven by a lifting hydraulic cylinder; the ejection pin device is a cylindrical ejection rod; and small wheels are arranged on the lower platform. According to the pin puller, the time for dismounting the pin is shortened, the labor intensity is alleviated, the working efficiency is improved, in addition, the structure is simple, the cost for processing materials is low, the operation is convenient, the practicality is good, and the pin puller is safe and reliable.
Description
Technical field
The utility model relates to a kind of pin removal.
Background technology
The biggest problem that at present field, colliery is aboveground runs into when tearing support open is the connection pin between hydraulic support back timber, the tail boom, because he is big and be that is pressing at two, uses crane can not guarantee well that connecting pin does not receive very big power; The son of pulling pin at present uses traditional hammer that gets rid of; Need two personal great strength to take turns whipping, can not dismantle a pin, and not only increase working strength of workers in 20 minutes; And efficient is low, has seriously restricted the working face installation progress.
The utility model content
The utility model provides a kind of pin removal, can shorten and unload the pin time, alleviates labor strength, increases work efficiency.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of pin removal comprises hydraulic support; Hydraulic support is provided with the hydraulic cylinder of pulling pin; The hydraulic cylinder of pulling pin of tailpiece of the piston rod is provided with the top tube, and piston rod is connected with the ejector pin device, and the ejector pin device passes setting in the tube of top.
Described hydraulic support comprises upper mounting plate and lower platform, between upper mounting plate and the lower platform crane is set, and crane is driven by the lifting hydraulic cylinder that is provided with.
Described ejector pin device is cylindrical push rod.
Described lower platform is provided with steamboat.
The utility model can shorten and unloads the pin time, alleviates labor strength, increase work efficiency, and simple structure, rapidoprint cost is low, easy to operate, practical, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of pin removal comprises hydraulic support; Hydraulic support comprises upper mounting plate 1 and lower platform 2; Between upper mounting plate 1 and the lower platform 2 crane 3 is set, upper mounting plate 1 is provided with the hydraulic cylinder 6 of pulling pin, and the hydraulic cylinder 6 of pulling pin of tailpiece of the piston rod is provided with top tube 7; Piston rod is connected with ejector pin device 8, and ejector pin device 8 passes setting in top tube 7.Ejector pin device 8 is cylindrical push rod, and lower platform 2 is provided with steamboat 4, and crane 3 is driven by the lifting hydraulic cylinder that is provided with 5.
When work; Promoting this pin removal makes it be rolled into the place to use; The upper and lower plate valve of stirring lifting hydraulic cylinder 5 rises to proper height (cylinder head of pulling pin can get final product with the pin that needs are pulled out is parallel) with upper mounting plate 1, and the plate valve of stretching, contract of stirring the hydraulic cylinder 6 of pulling pin is stretched the hydraulic pressure cylinder head, and ejector pin device 8 front ends are fixed by bolts in the bolt hole of gib head; And then the plate valve of stretching, contract of stirring the hydraulic cylinder 6 of pulling pin makes hydraulic cylinder getting back slowly, and pin just and then has been brought out like this.
Concrete beneficial effect:
1, practices thrift the time of the son of pulling pin greatly.Hammer is got rid of in use in the past needed more than 20 minute just can extract pin, only needed just can pull out in 2 minutes now, had improved removal efficiency greatly;
2, simple to operation, safe and reliable.Be to fall on the ground in the past, and might pound personnel or smash that hydraulic tube is first-class on the ground, and the people stands in will use with great strength under the unprotected situation of eminence and get rid of hammer with getting rid of to hammer into shape just extracting a big pin, very dangerous.And personnel only need stir plate valve now, and are also fixing on cylinder head after pin is pulled out, and only need loosening screw to take off and get final product, and speed is slow, people's phenomenon can not occur pounding;
3, a large amount of manpowers have been saved.The son of in the past pulling pin needs two people to make much ado just to pull out, and the next door also to have a people at any time then pin with get rid of hammer.Phenomenon only needs a people just can easily solve;
4, draw materials conveniently.This equipment key part all is that hydraulic support itself just has, and uses and finishes and can also use as the spare part of support, so need not painstakingly go to plan the waste of material financial resources, can on any support, get at any time when needing.
