Abstract
A hydraulic lock and a hydraulic column with a built-in safety valve belong to a coal mine machinery area, including a stigma, a ring-shaped cavity and a circular-shaped cavity arranged beneath the stigma, which link to a hydraulic lock and a safety valve and are characterized in that the stigma has a hydraulic lock cavity and a safety valve cavity inside, the hydraulic lock cavity, the safety valve cavity and the circular-shaped cavity and the ring-shaped cavity of the hydraulic column intercommunicates through a corresponding through-hole and the various parts of the hydraulic lock and that of the valve core of the safety valve are directly arranged in the corresponding cavity. The utility model puts inside the hydraulic lock and the safety valve, makes the hydraulic lock and the safety valve difficult to damage and also simplifies the external structure of the column. For the separate operation of the hydraulic column, arrange the control valve, which controls the movement of the column, on the stigma of the hydraulic column to save the high-pressure pipe from the column to the control valve.
Description
Technical field
The utility model relates to a kind of hydraulic lock and the built-in hydraulic column of safety valve, belongs to the coal mine machinery field.
Background technology
At present relatively large hydraulic column is all installed hydraulic lock and safety valve on the column cap of pillar or cylinder body under coal mine, the method of installing all has a common characteristic just to be mounted in the external surface of pillar, the problem that exists is easily to be damaged by collision at work, in addition, if need to use separately a hydraulic column in specific place, total control valve need be directly installed on this hydraulic column, can save the high-voltage tube of pillar like this to control valve, easy to operate control, if hydraulic lock and safety valve are installed on the column cap, so total bad installation of control valve.
The utility model content
The utility model technical issues that need to address are, at hydraulic lock in the prior art and the external easy impaired defective of safety valve, need redesign a kind of hydraulic device structure in order to overcome these defectives, the purpose of this utility model provides a kind of hydraulic lock and the built-in hydraulic column of safety valve, solves the problem of hydraulic lock and the bad installation of the external fragile and total control valve of safety valve.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
The hydraulic column that the utility model hydraulic lock and safety valve are built-in, comprise column cap, be arranged on circular cavity and annular chamber and the hydraulic lock that is connected with them and the safety valve of column cap below, in described column cap, have hydraulic lock chamber and safe valve pocket, be provided with corresponding through hole between the circular cavity of hydraulic lock chamber, safe valve pocket, hydraulic column and the annular chamber and be connected, each part of the spool portion of hydraulic lock and safety valve is directly installed in the corresponding chamber.
The spool of described hydraulic lock and safety valve can be installed in respectively in the shell type valve body corresponding with hydraulic lock chamber and safe valve pocket size, they is installed in respectively in the corresponding chamber again.
Described hydraulic lock chamber and safe valve pocket are radially or axially.
The outside of described column cap can also be provided with control valve.
The beneficial effects of the utility model: hydraulic lock of the present utility model and safety valve are built-in, make hydraulic lock and safety valve not fragile, have also realized the interior connection between the cavity simultaneously; The post external structure is easy in addition, for needing the hydraulic prop occasion of operation separately, the control valve of control pillar action can be installed on the column cap of hydraulic column, can save the high-voltage tube from the pillar to the control valve like this.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the column cap structural representation of existing external hydraulic column;
Fig. 2 is the internal construction schematic diagram of column cap part of the present utility model;
Fig. 3 is the schematic diagram of the utility model external belt control valve;
The specific embodiment
With reference to Fig. 1 is prior art external hydraulic column column cap 1 part, and hydraulic lock 2 and safety valve 3 are installed in the outside of column cap 1.With reference to Fig. 2 is the column cap part of the built-in hydraulic column of the utility model hydraulic lock and safety valve, comprise column cap 1, be arranged on circular cavity and annular chamber and the hydraulic lock 2 that is connected with them and the safety valve 3 of column cap 1 below, in described column cap 1, have axial hydraulic lock chamber 4 and the safe valve pocket 5 radially below it, be provided with corresponding through hole between the circular cavity of hydraulic lock chamber 4, safe valve pocket 5, hydraulic column and the annular chamber and be connected, each part of the spool portion of hydraulic lock 2 and safety valve 3 is installed in the corresponding chamber.
Be one of the present utility model with reference to Fig. 3 and improve embodiment, control valve is installed outside column cap again.
Claims (4)
1, the built-in hydraulic column of a kind of hydraulic lock and safety valve, comprise column cap, be arranged on circular cavity and annular chamber and the hydraulic lock that is connected with them and the safety valve of column cap below, it is characterized in that: in described column cap, have hydraulic lock chamber and safe valve pocket, be provided with corresponding through hole between the circular cavity of hydraulic lock chamber, safe valve pocket, hydraulic column and the annular chamber and be connected, each part of the spool portion of hydraulic lock and safety valve is directly installed in the corresponding chamber.
2, the built-in hydraulic column of hydraulic lock as claimed in claim 1 and safety valve, it is characterized in that: each part of the spool portion of described hydraulic lock and safety valve is installed in respectively in the shell type valve body corresponding with hydraulic lock chamber and safe valve pocket size, they is installed in respectively in the corresponding chamber again.
