Abstract
The invention discloses a pin pulling device which is high in working efficiency and safe and reliable to operate. The pin pulling device comprises a base plate and a support frame. The support frame and the base plate are connected fixedly and integrally. A through hole is formed in the support frame. A connecting screw is mounted in the through hole. Hydraulic support columns are arranged on two sides of the support frame. An integrated structure of the base plate and the support frame is adopted, the connecting screw is mounted in the through hole in the support frame, and the hydraulic support columns are arranged on the two sides of the support frame; when the pin pulling device is in use, a to-be-demounted machine part is disposed above the support frame, the connecting screw is in screw joint with a connecting pin integrally, the upper ends of the hydraulic support columns are abutted against the machine part, and the connecting screw on the machine part is pulled out from the machine part through working of the hydraulic support columns. The hydraulic support columns are adopted to serve as power, application of force is stable, and impact on the connecting pin is reduced, so that pin puling efficiency is high, safety and convenience are realized, and the machine part is less prone to damage.
Description
Technical field
The present invention relates to a kind of instrument, especially for the special demounting device of the connecting pin of heavy mechanical equipment under coal mine.
Background technology
The speed that withdraws of mine shearer group is directly relevant with Safety of Coal Mine Production and economic benefit, and one of key that decision withdraws speed is the speed of disassembling unit equipment, and the speed of disassembling unit equipment depends primarily on the time of dismounting hinge pin.When the dismounting unit equipment, mainly used guide chain by after unit parts lifting pretension in the past, and used iron hammer that attachment pegs is knocking-on, aforesaid operations is all to adopt manual type.When the operation narrow space, the attachment pegs corrosion is out of shape in serious situation, and it is slow that the method is disassembled unit speed, and potential safety hazard is many, and efficiency is low.In the process of Reusability guide chain lift adjustment position, the bad grasp of unit parts stressing conditions, repeated multiple times, the time taken is long, has the unsafe factors such as guide chain or chainlet chain rupture.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned prior art exists, provide a kind of high efficiency and handling safety reliable pin pulling out device.
The technical solution adopted in the present invention is: comprise base plate and the support fixed as one with base plate, be provided with through hole above support, the connection spiral shell is housed in through hole, the support both sides are equipped with hydraulic prop.
On described base plate, the hydraulic prop below is equipped with draw-in groove, and the bottom of hydraulic prop coordinates with the draw-in groove clamping.
Above described support, set through hole also can adopt screw.
The structure that adopts base plate and support to be integrated in the present invention, and in the through hole of support top, the connection spiral shell is housed, be provided with hydraulic prop in the support both sides.During use, split parts are placed in to support top, the attachment pegs on split parts is over against connecting spiral shell, will connect spiral shell and attachment pegs and be spirally connected and be integrated, and the upper end of hydraulic prop withstands on parts, by the work of hydraulic prop, the connection spiral shell on parts is transferred to from parts.Owing to adopting hydraulic prop to be used as power, the application of force is steady, has reduced the impact to attachment pegs, and not only finger efficiency is high, and safe ready, also is difficult for parts are caused to damage.
The accompanying drawing explanation
Fig. 1 is the schematic perspective view of structure of the present invention.
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of Fig. 1.
Fig. 3 is working state schematic representation of the present invention.
Fig. 4 is the cut-away illustration of Fig. 3.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but does not form any limitation of the invention.Shown in Fig. 1 and Fig. 2, the present invention includes base plate 1 and with the support 2 that base plate 1 fixes as one, be provided with through hole above support 2, be equipped with in through hole and connect spiral shell 4, support 2 both sides are equipped with hydraulic prop 3.For preventing that hydraulic prop 3 from sliding, can on base plate 1, draw-in groove be set, the bottom of hydraulic prop 3 is coordinated with the draw-in groove clamping.Above described support 2, set through hole also can adopt screw.
During operation, split parts 5 are placed in to support 2 tops, by the attachment pegs 6 on split parts 5 over against connecting spiral shell 4, to connect spiral shell 4 and be spirally connected and be integrated with attachment pegs 6, then the upper end of hydraulic prop 3 be withstood on parts 5, by stretching out of hydraulic prop 3, parts 5 upwards be pushed up, and connect spiral shell 4, attachment pegs 6, support 2 and base plate 1 are connected as one, integral body remains unchanged, and makes attachment pegs 6 and parts 5 that relative motion occur, and attachment pegs 6 is transferred to from parts 5 the most at last.Owing to adopting hydraulic prop 3 to be used as power, the application of force is steady, has reduced the impact to attachment pegs 6, and not only finger efficiency is high, and safe ready, also is difficult for parts 5 are caused to damage.
Claims (3)
