Abstract
A reversing valve self-locking device for a hydraulic support comprises a reversing valve, and is characterized in that the two sides of the reversing valve are correspondingly provided with fixing devices and a locking ring, and the locking ring is connected with the two fixing devices. According to the utility model, the reversing valve is convenient for the breaking of self-locking when used. When the reversing valve is not used, the self-locking is convenient and reliable, thereby ensuring no maloperation.
Description
Technical field
The utility model relates to a kind of hydraulic support selector valve self-locking device.
Background technique
The selector valve of the special-purpose support apparatus comprehensive mining hydraulic bracket in existing colliery mostly is hand-operated direction valve greatly, and because the interior working space narrow and small (particularly Bracket in Thin Coal Seam more so) of support, people's collision selector valve reversing handle when movable in support, cause the support misoperation, damage equipment, supporting performance lost efficacy, even can cause personal injury.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome above-mentioned defective, and easy to use, can effectively prevent the hydraulic support selector valve self-locking device of selector valve misoperation.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic support selector valve self-locking device, comprise selector valve, and it is characterized in that: the both sides correspondence of selector valve is provided with fixing device and block ring, and block ring connects two fixing devices.
Described fixing device comprises fixed plate, shaft seat and rotating shaft, and fixed plate is fixedlyed connected with selector valve, and shaft seat is fixed on the fixed plate, and rotating shaft is inserted in the shaft seat, and block ring is connected with rotating shaft.
During locking, block ring is fixed together by rotating shaft and shaft seat and fixed plate, and the selector valve handle stretches in the block ring, makes the selector valve handle not operate like this, realizes locking.To two sideway swivels, after block ring broke away from the selector valve handle, the selector valve handle can be operated freely, unlocking after block ring outwards moves in shaft seat with rotating shaft.
The beneficial effect that the utility model had is: it is convenient to remove self-locking when using selector valve; During without selector valve, self-locking is convenient, reliable, guarantees can not cause misoperation.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, block ring; 2, rotating shaft; 3, shaft seat; 4, fixed plate; 5, selector valve handle; 6, selector valve;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, a kind of hydraulic support selector valve self-locking device comprises selector valve 6, and the both sides correspondence of selector valve 6 is provided with fixing device and block ring 1, and block ring 1 connects two fixing devices.
Described fixing device comprises fixed plate 4, shaft seat 3 and rotating shaft 2, and fixed plate 4 is fixedlyed connected with selector valve 6, and shaft seat 3 is fixed on the fixed plate 4, and rotating shaft 2 is inserted in the shaft seat 3, and block ring 1 is connected with rotating shaft 2.
During locking, block ring 1 is fixed together with fixed plate 4 by rotating shaft 2 and shaft seat 3, and selector valve handle 5 stretches in the block ring 1, makes selector valve handle 5 not operate like this, realizes locking.To two sideway swivels, block ring 1 breaks away from selector valve handle 5 after block ring 1 outwards moves in shaft seat 3 with rotating shaft 2, and selector valve handle 5 can be operated freely, unlocking, but selector valve 6 free operants.
