Abstract
The utility model discloses a remote filling connection device of a hydraulic prop, and belongs to the technical field of hydraulic props. The remote filling connection device of the hydraulic prop comprises a filling mouth (1), a clamping sleeve (2) and a connection sleeve (3), wherein the clamping sleeve (2) is clamped on the filling mouth (1) in a sleeved mode, one end of the filling mouth (1) is connected with a three-use valve through the clamping sleeve (2), and the other end of the filling mouth (1) is connected with the connection sleeve (3). The remote filling connection device of the hydraulic prop achieves operation and control over the filling of the hydraulic prop in a remote mode, the damage to workers due to the phenomena such as slag falling or pushing off of a single body occurring in the propping process is effectively prevented, assembly and disassembly among parts are convenient, and operation is easy. In addition, the remote filling connection device of the hydraulic prop is simple in structure, easy to manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of hydraulic prop remote connecting device, and specifically the long-range fluid injection linkage of a kind of hydraulic prop, belong to the hydraulic prop technical field.
Background technology
At present, the normal hydraulic prop that uses in coal production, the rock by the top board to work plane and roof collapse carries out supporting, guarantees the safety of working space.Domestic hydraulic prop commonly used is divided into two kinds of piston type and plunger types.
Piston type single hydraulic cylinder is when supporting, and pressure fluid enters cylinder cavity through triple-use valve, and the post of living raises, and while to pressure-bearing, connecing top, stretches post and finishes, and completes and stretches post.When carrying out the aforesaid operations method, personnel all the time around individual prop, are prone to slag in the pillar process or monomer is pedaled out phenomenon, cause injury to personnel.
Summary of the invention
The problem existed for above-mentioned prior art, the utility model provides a kind of hydraulic prop long-range fluid injection linkage, can realize remote fluid injection, slag or the monomer effectively avoiding occurring in the pillar process such as pedal out at the injury of phenomenon to the staff, operation safe, the convenience.
To achieve these goals, the long-range fluid injection linkage of a kind of hydraulic prop of the utility model, comprise liquid injecting mouth, chucking cover and adapter sleeve, and the chucking cover is fastened on liquid injecting mouth, and liquid injecting mouth one end overlaps with triple-use valve and is connected by chucking, and the other end is connected with adapter sleeve.
The beneficial effects of the utility model are: this device has been realized the fluid injection of remote control hydraulic prop, slag or the monomer that have effectively prevented from occurring in the pillar process phenomenon such as are pedaled out the staff are damaged, it is convenient, simple to operate to install between each several part, remove.In addition, the utility model simple in structure, be easy to manufacture, cost is low.
The accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
In figure: 1, liquid injecting mouth, 2, chucking cover, 3, adapter sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the long-range fluid injection linkage of this hydraulic prop, by liquid injecting mouth 1, chucking cover 2 and adapter sleeve 3, chucking cover 2 is fastened on liquid injecting mouth 1, and liquid injecting mouth 1 one ends overlap 2 by chucking and are connected with triple-use valve, and the other end is connected with adapter sleeve 3.
As the utility model, further improve, described liquid injecting mouth 1 is threaded with adapter sleeve 3, also can adopt the connected mode of riveted joint, but riveted joint is installed, dismounting is inconvenient, so preferably be threaded.
When hydraulic prop, during at pillar, this device overlaps 2 by chucking and is clamped on triple-use valve, and adapter sleeve 3 is connected with flexible pipe, opens hosepipe switch, and liquid injects cylinder cavity by flexible pipe through liquid injecting mouth 1 and triple-use valve, completes pillar.Whole operating process, the staff only needs remote-controlled operation to complete, safe ready.After the pillar process completes, the staff only need rotate chucking cover 1 and this device can be exited from triple-use valve, installation, convenient disassembly.
Claims (2)
1. the long-range fluid injection linkage of hydraulic prop, it is characterized in that, comprise liquid injecting mouth (1), chucking cover (2) and adapter sleeve (3), chucking cover (2) is fastened on liquid injecting mouth (1), liquid injecting mouth (1) one end overlaps (2) by chucking and is connected with triple-use valve, and the other end is connected with adapter sleeve (3).
2. the long-range fluid injection linkage of a kind of hydraulic prop according to claim 1, is characterized in that, liquid injecting mouth (1) is threaded with adapter sleeve (3).
