Description

A kind of oil returning tube of splitter

Technical field:

The utility model relate to can be applicable to quarry, rock, concrete splitter technical field in the mine, capital construction, refer in particular to a kind of oil returning tube of splitter.

Background technology:

In quarrying industry, mining industry and foundation construction field, often rock that need volume is bigger, concrete division, traditional mode adopts manual work more.That is, drill rod is inserted in rock, the concrete, make it split into the less fragment of volume with iron hammer.But this manual work mode inefficiency, and the personnel that cause easily injure.For this reason, at present more adopt mechanical systems rock, concrete are divided, split broken, shatter machine etc. for example.But these mechanical facility volumes are bigger, can't use for some particular locations (for example on the halfway up the hill, the higher zone of floor), can produce bigger noise and impact force during these plant equipment work simultaneously, bring discomfort to operating personnel.

At the problems referred to above, the splitter that a kind of build is less, be fit to handwork is arranged in the market.This splitter be with hydraulic oil as energy source, the head of splitter is inserted crack in rock or the concrete, can be in the short time of several seconds by oil pressure with huge rock, the concrete division of thousands of tons of.The common structure of this splitter is as follows: it comprises a division oil cylinder, and the piston rod end of division oil cylinder connects a division head, and the division oil cylinder moves under the drive of hydraulic oil.During use, in the crack in division head insertion rock or the concrete, open splitter then, vertically the piston rod of operation will drive the division head and produce the power of laterally splitting, thereby rock, concrete are divided.

This splitter is because volume is little, high efficiency, and work the time does not have impact, noiselessness and advantage such as economical and practical is extensive use of at present.But also there is certain deficiency in this splitter:

Because splitter adopts the oil pressure mode to drive the operation of division mechanism, when piston moved in oil cylinder, the compression chamber that needs an oil return pipe will divide oil cylinder was communicated with oil outlet.Oil return pipe at present adopts a seamless steel pipe as oil duct, then seamless steel pipe is welded on the outer wall of cylinder block, and the two-port of this seamless steel pipe is welded with compression chamber that divides oil cylinder and oil return opening respectively.The shortcoming that this structure can produce is exactly:

1, because oil return pipe is located on the outer casing wall of oil cylinder, make the surface structure of whole splitter not smooth, moulded not attractive in appearance;

2, welding procedure processing trouble, processing cost is higher;

3, the oil return pipe that forms by welding procedure in use occurs oil pipe easily and comes off, and perhaps occurs revealing because of not prison welding causes hydraulic oil;

4, in the welding process of oil cylinder casing wall and oil return pipe port, higher to technological requirement, otherwise easily failure welding appears and the situation that causes oil duct to stop up.

The utility model content:

Technical problem to be solved in the utility model is exactly in order to overcome the deficiency of present product, and a kind of oil returning tube of simple in structure, the splitter being convenient to process is provided.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this splitter comprises: the division oil cylinder, be positioned at the in-oil cylinder piston of division, with fixing piston rod of piston and the division head that is connected with piston rod, the oil returning tube in the described division oil cylinder is opened in the casing wall that divides oil cylinder.

Described oil returning tube comprises: vertically be opened in oil return pipe in the casing wall, laterally be opened on the casing wall two sections and cross oil pipes, cross oil pipes for these two sections and respectively the two ends of oil return pipe are communicated with oil cylinder cavity and oil outlet.

After the utility model adopted said structure, it was set directly at oil returning tube in the casing wall of division oil cylinder, promptly offers the passage of an elongated hole as oil returning tube on the casing wall of division oil cylinder.The utility model will have following advantage after adopting this structure:

1, the utility model is hidden in oil returning tube in the casing wall of division oil cylinder, can optimize the structure of division cylinder block like this, promotes the overall aesthetics of splitter.

2, adopt this mechanism can alleviate the body weight of splitter, simplified processing technology.

3, oil returning tube directly is opened in the casing wall, and promote its application life greatly;

4, the situation that the oil returning tube that causes because of welding stops up can not appear;

5, because oil returning tube directly forms, need not external pipe on division oil cylinder casing wall, so just saved material, reduce production cost.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an enlarged diagram of the present utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

See Fig. 1,2, this is a rock, concrete splitter, and it comprises: division oil cylinder 1, be positioned at the piston 2 of division oil cylinder 1, the piston rod of fixing with piston 23 and the division head 5 that is connected with piston rod 3.The cavity that piston 2 will divide in the oil cylinder 1 is divided into upper end cavity and lower end cavity.

The end of division oil cylinder 1 offers two

turnover oilholes

11,12, and hydraulic oil will be by these two oilhole turnover division oil cylinders 1.Oil returning tube 6 in the described division oil cylinder 1 is opened in the casing wall of division oil cylinder 1.This oil returning tube 6 comprises: vertically be opened in oil return pipe 61 in the casing wall, laterally be opened on the casing wall two sections and

cross oil pipes

62,63, this two is crossed

oil pipe

62,63 and respectively the two ends of oil return pipe 61 is communicated with oil cylinder 1 lower end cavity and oil outlet 12.Adding man-hour, at first, an elongated passage (not connecting casing wall) is vertically offered as oil return pipe 61 in end by division oil cylinder 1 port, two through holes are laterally offered as crossing

oil pipe

62,63 in two positions on the casing wall of division oil cylinder 1 then, wherein cross the end that oil pipe 62 passes oil return pipe 61 and directly be communicated with, promptly cross oil pipe 62 and connect casing walls with the lower end cavity of division oil cylinder 1.Another is crossed the other end that oil pipe 63 passes oil return pipe 61 and is communicated with oil outlet 12.At last, with the openend of oil return pipe 61, the openend obstruction of crossing the casing wall outside of

oil pipe

62,63, so just formed an oil returning tube with plug cock.

When using the utility model, at first piston rod 3 resets, in the crack on division head insertion rock, the concrete.Then open splitter, high-pressure and hydraulic oil is entered in the upper end cavity of division oil cylinder 1 by fuel feed hole 11, in the cavity of upper end under the pressure effect of oil pressure, piston 2 drives piston rod 3 to begin to move down, hydraulic oil in the cavity of oil cylinder lower end will flow into outlet opening 12 by oil returning tube 6, form oil return, and the hydraulic oil that so just forms in the division oil cylinder 1 upper end cavity constantly increases, hydraulic oil in the cavity of oil cylinder lower end constantly reduces, and moves down thereby constantly promote piston rod 3.Piston rod 3 drives 5 motions of division head simultaneously, and the piston rod 3 that vertically moves this moment will drive division head 5 and produce the power of laterally splitting, thereby with rock, concrete division.

Certainly, the above only is the utility model example, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
