Description
Technical field
The present invention relates to a kind of hydraulic locking apparatus, particularly a kind of two-way wedge shape hydraulic locking apparatus.
Background technique
In the engineering construction operation in modern times, use locking device widely.Locking device is in multiple industries such as building, bridge, harbour, petrochemical industry, electric power, metallurgy during with big weight, large size structure or equipment wholely promote, climb, decline and slippage adhere to specification with formation to the height of setting building or equipment, play a part very importantly, also be that hydraulic pressure whole promotes, climbs, whether safe can decline, slippage successfully and move reliable assurance.Locking device in the existing hydraulic pushing oil cylinder occurs easily that tight anchor is unreliable, steel strand become flexible in the course of the work, intermediate plate working life is broken situations such as intermediate plate screw during short, loose anchor easily.
For overcoming the problem that above-mentioned prior art exists, notice of authorization number is CN2565795Y, name is called in the utility model patent of " a kind of clamp device of hydraulic lift(ing) cylinder ", piston, piston is housed in the ground tackle cylinder block installs and be supported on the anchoring part, and anchoring part and bearing are solidified as a whole.On the cover board, the position corresponding with anchor hole has spring socket, and spring is housed in spring seat, upwards withstands cover plate, pushes down the intermediate plate top downwards.The top cover is housed between the intermediate plate in supporting plate and the anchor hole, and the top cover upwards withstands the intermediate plate bottom, withstands supporting plate downwards.But still have the following disadvantages: the complex structure of locking device, can only realize one-way locking, after being subjected to force direction oppositely, can not realize locking function.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, solve the problem that in the modern project construction operation, how to realize bidirectional locking, a kind of two-way wedge shape hydraulic locking apparatus is provided.
The two-way wedge shape hydraulic locking apparatus that the present invention proposes comprises left anchoring part, right anchoring part, ground tackle driving lever, spring, two-way wedge shape ground tackle and hydraulic pushing oil cylinder.Wherein: the hydraulic pushing oil cylinder is made up of cylinder body and piston rod, and piston rod one end of hydraulic pushing oil cylinder passes the through hole on the right anchoring part, and the rod end of piston rod is welded on the left anchoring part; The cylinder body end face of hydraulic pushing oil cylinder is welded on the right anchoring part; Two-way wedge shape ground tackle is made up of 2 intermediate plates, and intermediate plate is wedge shape, adopts the tooth form of del, and the tapering at two ends is 7 degree, half to 9 degree half, and the number of teeth is the 60-90 tooth; Being welded with respectively on the ground tackle driving lever on two intermediate plates up and down of two-way wedge shape ground tackle; Left side anchoring part is connected with welding manner with corresponding ground tackle driving lever by spring respectively with right anchoring part; Utilize the ground tackle driving lever to regulate the position of two-way wedge shape ground tackle, make two-way wedge shape ground tackle be positioned at the neutral position of left anchoring part and right anchoring part all the time; Between 2 intermediate plates of the two-way wedge shape ground tackle of steel wire penetrating, and the center hole of left anchoring part, right anchoring part.
The present invention has following several big advantage:
1, for construction operation provides a kind of two-way wedge lock mechanism, can effectively realize the bidirectional locking function;
2, utilize the ground tackle driving lever can regulate the position of two-way wedge shape ground tackle, make it be positioned at the neutral position of left anchoring part and right anchoring part all the time;
3, intermediate plate adopts the tooth form of del, and after the increase of the tapering of intermediate plate, when tension of steel strand was identical again, intermediate plate reduced the clamping force of steel strand, and damage reduces to steel strand surface;
4, the increase of the intermediate plate number of teeth has increased the interlock of intermediate plate with steel strand, has avoided steel strand loosening dangerous, has reduced wearing and tearing, has prolonged the working life of intermediate plate, has improved economic benefit.
5, the present invention is simple and reasonable, and is easy to process, reliable operation.
Description of drawings
Fig. 1 is two-way wedge shape hydraulic locking apparatus.
Fig. 2 is the assembling left view of two-way wedge shape ground tackle.
Number in the figure: 1 is left anchoring part, and 2 is the ground tackle driving lever, and 3 is spring, and 4 is two-way wedge shape ground tackle, and 5 is the hydraulic pushing oil cylinder, and 6 is right anchoring part, and 7 is wire rope.
Embodiment
The invention will be further described below in conjunction with accompanying drawing, but protection scope of the present invention is not limited thereto.
The present invention has provided a kind of two-way wedge shape hydraulic locking apparatus, comprises left anchoring part 1, ground tackle driving lever 2, spring 3, two-way wedge shape ground tackle 4, hydraulic pushing oil cylinder 5 and right anchoring part 6.
The piston rod of hydraulic pushing oil cylinder 5 passes the through hole on the right anchoring part 6, and the rod end of piston rod is welded on the left anchoring part 1.The cylinder body end face of hydraulic pushing oil cylinder 5 is welded on the right anchoring part 6.Two-way wedge shape ground tackle 4 is made up of 2 intermediate plates, and intermediate plate is wedge shape, adopts the tooth form of del, and the tapering at two ends is 7 degree, half to 9 degree half, and the number of teeth is the 60-90 tooth.Two-way wedge shape ground tackle 4 be welded with a ground tackle driving lever 2 respectively on two intermediate plates up and down.A left side anchoring part 1 and right anchoring part 6 are connected with welding manner by spring 3 and ground tackle driving lever 2 respectively.Utilize ground tackle driving lever 2 can regulate the position of two-way wedge shape ground tackle 4, make it be positioned at the neutral position of left anchoring part 1 and right anchoring part 6 all the time.Wire rope 7 passes between 2 intermediate plates of two-way wedge shape ground tackle 4, and the center hole of left anchoring part 1 and right anchoring part 6.
