Description
Technical field
The utility model relates to a kind of dredger clamping foundry goods device, a kind of special operation dredger clamping cast system.
Background technology
In recent years, along with the development of Chinese manufacturing technology, China actively introduces, digest, absorb advanced foreign technology, also promote the development of Chinese hydraulic excavator, some shortcomings before compensate for reform and opening-up, but it is undeniable, although China is excavator manufacture big country, but generally speaking, high-quality, also have larger gap for the excavator of special work post and relevant foundry goods compared with external advanced excavator manufacture country, therefore, devise a kind of special operation dredger clamping cast system.
Summary of the invention
In order to solve above-mentioned Problems existing, the special operation dredger clamping cast system that the utility model provides a kind of compact conformation, advanced technology, chucking power large.
The utility model is achieved through the following technical solutions:
A kind of special operation dredger clamping cast system, comprises bolt, main oil cylinder piston, master cylinder cylinder body, O RunddichtringO, round key, slips, spring, auxiliary oil cylinder piston, auxiliary oil cylinder cylinder body, stop collar, slip spider; The described master cylinder cylinder body left side is by bolt tightening; O RunddichtringO is equipped with in described master cylinder cylinder body bottom surface; Described slips is arranged on slip spider; Described auxiliary oil cylinder piston moves in auxiliary oil cylinder cylinder body; Described slip spider is bolted on guide rail by slip spider; Described spring is contained in spring housing inside.
As further prioritization scheme of the present utility model, described main oil cylinder piston can move in master cylinder cylinder body, and cylinder efficient pressure is 16MPa.
As further prioritization scheme of the present utility model, described stop collar is bolted on support by stop collar.
As further prioritization scheme of the present utility model, described spring can free-extension in spring housing, and the maximum pretightning force that spring produces is 22.38kN.
Compared with prior art, the beneficial effects of the utility model are: the use of (1) spring housing, and spring can be avoided because of the flexible excessive and distortion that produces, prolongation spring application life; (2) design of guide rail, can improve the flexibility of clamper, can adapt to special operation environment; (3) design of latch, freely can adjust slips according to the concrete service condition of clamper.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, bolt; 2, main oil cylinder piston; 3, master cylinder cylinder body; 4, O RunddichtringO; 5, round key; 6, latch; 7, slips; 8, spring; 9, spring housing; 10, auxiliary oil cylinder piston; 11, auxiliary oil cylinder cylinder body; 12, support; 13, stop collar bolt; 14, stop collar; 15, guide rail; 16, slip spider bolt; 17, slip spider.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As Fig. 1, a kind of special operation dredger clamping cast system, comprises bolt 1, main oil cylinder piston 2, master cylinder cylinder body 3, O RunddichtringO 4, round key 5, slips 7, spring 8, auxiliary oil cylinder piston 10, auxiliary oil cylinder cylinder body 10, stop collar 14, slip spider 17; Described master cylinder cylinder body 3 left side is tightened by bolt 1; O RunddichtringO 4 is equipped with in described master cylinder cylinder body 3 bottom surface; Described slips 7 is arranged on slip spider 17; Described auxiliary oil cylinder piston 10 moves in auxiliary oil cylinder cylinder body 11; Described slip spider 17 is fixed on guide rail 15 by slip spider bolt 16; It is inner that described spring 8 is contained in spring housing 9.
Described main oil cylinder piston 2 can move in master cylinder cylinder body 3, and cylinder efficient pressure is 16Mpa.Oil cylinder is identical with auxiliary oil cylinder cylinder body 11 with master cylinder cylinder body 3, ensures the continuity of chucking power.
Described stop collar 14 is fixed on support 12 by stop collar bolt 13.Support 12 is positioned at bottom master cylinder cylinder body 3 and auxiliary oil cylinder cylinder body 11.
Described spring 8 can free-extension in spring housing 9, and the maximum pretightning force that spring 8 produces is 22.38KN.
During work, hydraulic power is passed to the fixing main oil cylinder piston 2 of bolt 1 by excavator, make its stretching motion in master cylinder cylinder body 3, slips 7 starts to rotate, fixed by round key 5 in the middle of slips 7 and slip spider 17, slip spider 17 is so just driven to move left and right on the guide rail 15 be fixed on support 12, spring 8 in spring housing 9 is flexible produces pretightning force, the whole clamper system motion of such drive, the design of O RunddichtringO 4, the leakage of hydraulic oil can be prevented, the use of stop collar 14, can ensure that clamper leaves and entirely not exceed predetermined limit position, extend the application life of blessing system.
More than show and describe general principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
