Abstract
A kind of New Coal Mine rig feed cylinder, it is by oil cylinder main body and addedly form, and it is characterized in that described oil cylinder main body is arranged added, described added end two side respectively arranges a straight-through oil nozzle.Coal mine drilling machine is when the elevation angle works, and hydraulic oil pipe no longer affects by installing space and produces stressed bending, and does not affect rig and freely works in its elevation coverage, add the working life of hydraulic oil pipe, stop potential safety hazard, reduction cost of equipment maintenance.
Description
Technical field
The utility model relates to a kind of feed cylinder, is specifically related to a kind of New Coal Mine rig feed cylinder.
Background technique
In prior art, coal mine drilling machine feed cylinder and hydraulic oil pipe are connected with two the right angle oil nozzles being disposed in parallel in oil cylinder side by rapid pipe joint, the drawback of such existence is the restriction due to installing space, when rig is in elevation angle work, the stressed generation of hydraulic oil pipe bends, the hydraulic oil pipe be in for a long time under stressed bent state is easily aging, working life reduces, and hydraulic oil liquid occurs and reveals, security incident can occur time serious.Cost of equipment maintenance increases, and there is potential safety hazard simultaneously.
Summary of the invention
The purpose of this utility model is exactly to solve hydraulic oil pipe stressed bending drawback when the coal mine drilling machine elevation angle works, and then provides a kind of New Coal Mine rig feed cylinder.
The stressed bending generation of hydraulic oil pipe is because connected two right angle oil nozzles are arranged on the side of oil cylinder, when therefore working at the coal mine drilling machine elevation angle, high-pressure oil pipe is in stressed bent state by the impact of installing space always, in order to address this problem, the utility model devises new feed cylinder and the linkage structure of hydraulic oil pipe.
A kind of New Coal Mine rig feed cylinder, it is by oil cylinder main body and addedly form, and it is characterized in that described oil cylinder main body is arranged added.
Described added end two side respectively arranges a straight-through oil nozzle.
the utility model beneficial effect: coal mine drilling machine is when the elevation angle works, and hydraulic oil pipe no longer produces stressed bending because of the impact of installing space, and does not affect rig and freely work in its elevation coverage, adds the working life of hydraulic oil pipe, stops potential safety hazard, reduction cost of equipment maintenance.
accompanying drawing explanation
Fig. 1 structural drawing of the present utility model;
Fig. 2 is the structural drawing of straight-through oil nozzle;
Wherein: 1-oil cylinder main body; 2-is added; 3-leads directly to oil nozzle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A New Coal Mine rig feed cylinder as shown in Figure 1, it is made up of oil cylinder main body 1 and added 2, it is characterized in that described oil cylinder main body 1 is provided with added 2, and the described end of added 2 two side respectively arranges a straight-through oil nozzle 3.
Added 2 end two STHs, make two straight-through oil nozzles 3 be placed in two sides of added 2 respectively.Under this state during connecting fluid pressuring oil pipe, no matter the rig elevation angle is much, hydraulic oil pipe all can not produce stressed bending because of installing space impact, only be in natural torsion state, by the design of this linkage structure, thus reach the working life adding hydraulic oil pipe, stop potential safety hazard, reduce the object of cost of equipment maintenance.
