Abstract
The utility model relates to an operation mechanism for a mining hydraulic valve group, in particular to a shutting-type handle for an operation valve group of a hydraulic bracket. The shutting-type handle comprises a valve seat, a lock rod, a compression spring, a handle and a handlebar; an internal chamber of the handle has a ladder-shaped structure; the lock rod has a ladder-shaped structure; the lock rod and the compression spring are arranged in the handle; one end of the lock rod is connected with the handlebar; the semi-round top end of the valve seat is provided with a blind hole; and the other end of the lock rod is embedded in the blind hole. Compared with the prior art, the semi-round top end of the valve seat is provided with a blind hole and the other end of the lock rod is embedded in the blind hole, thus realizing a shutting-type structure; the handle can be pushed and pulled to realize the action of the next step by manually pulling one end of the lock rod out of the blind hole in the axial direction of the lock rod; and when the handle is subjected to the accidental force, the error action can not be generated, thus ensuring the reliability of the hydraulic bracket.
Description
Technical field:
The utility model relates to a kind of mining hydraulic valve bank operating mechanism, particularly a kind of hydraulic support operation valve group enclosed type handle.
Background technology:
Because hydraulic support is being born the support action of face roof under the coal mine, the standard action of its each position hydraulic cylinder, safety in production to coal mine is most important, and the action of the standard of each position hydraulic cylinder is what to control by the operating mechanism of valve group, mechanism is mainly used to every function action of control valve group, thereby realizes the lifting, passing, balance of hydraulic support, every function such as flexible.
Traditional operating mechanism is: install additional in the handle bottom and bump pearl and cooperate with spring, form three, that is: " 0 " position and " pushing away ", " drawing " position self-locking.When handle is subjected to external force, such as the unexpected masterpiece time spent such as kicking, spoil is pounded, misoperation very easily takes place, cause the hydraulic support action that meets accident, cause equipment and personnel's unexpected injury, it is totally unfavorable that safety in production is down advanced in the colliery.
The utility model content:
Goal of the invention of the present utility model is to overcome the deficiency of background technology and provides a kind of hydraulic support that can avoid maloperation minimizing unexpected injury generation takes place to operate valve group enclosed type handle.
The utility model adopts following technical scheme:
A kind of hydraulic support operation valve group enclosed type handle, comprise valve seat, locking bar, stage clip, handle, handgrip, the stepped structure of its inner chamber of described handle, the stepped structure of described locking bar, this locking bar and stage clip all place in the handle, one end of this locking bar is connected with described handgrip, and the semicircle top of described valve seat is provided with blind hole, and the other end of described locking bar embeds in this blind hole.
The utility model of employing technique scheme compared with prior art, the semicircle top of valve seat is provided with blind hole, the other end of locking bar embeds in this blind hole, thereby realized a kind of enclosed type structure, have only by manually along the axial ray of lock rod direction one end of locking bar being extracted from blind hole, the action that just can push away, handle is realized next step is when handle is subjected to the unexpected masterpiece time spent, misoperation can not take place, thereby guaranteed the reliability of hydraulic support.
As a kind of preferred version of the present utility model, the locking bar aperture of the slightly larger in diameter of described blind hole in embedding it.
As a kind of preferred version of the present utility model, sealing ring is equipped with at the two ends of described handle respectively.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
A kind of hydraulic support operation valve group enclosed type handle is referring to accompanying drawing 1, among the figure: valve seat 1, blind hole 2, the first sealing rings 3, stage clip 4, locking bar 5, handle 6, the second sealing rings 7, handgrip 8.
In the present embodiment, referring to accompanying drawing 1, the stepped structure of handle 6 its inner chambers, the also stepped structure of locking bar 5, locking bar 5 and stage clip 4 all place in handle 6 its inner chambers, as shown in fig. 1, stage clip 4 is sleeved on the part of locking bar 5 stepped structure medium-small diameter, and is inlaid in the major diameter part of handle 6 stepped inner chambers, and an end of locking bar 5 is provided with screw thread and is connected with handgrip 8, the semicircle top of valve seat 1 is provided with blind hole 2, and the other end of locking bar 5 embeds in the blind hole 2.
As a kind of preferred structure of present embodiment, blind hole 2 diameters are larger than the aperture of the locking bar 5 in it, plug and unplug when being convenient to manually-operated.
A kind of preferred structure as present embodiment, sealing ring all is equipped with at the two ends of handle 6, be respectively first sealing ring 3 and second sealing ring 7, first sealing ring 2 be contained in that handle 6 matches with locking bar 5 the inner chamber place, second sealing ring 7 is sleeved on the external surface of handle 6, as shown in Figure 1, i.e. the position that joins of the inner surface of the external surface of handle 6 and handgrip 8, it is favourable that to prevent that the coal water breakthrough from going into handle 6 inner and cause locking bar 5 malfunctioning.
When handle 6 was in position, valve seat 1 middle part " 0 ", locking bar 5 inserted in the blind hole 2 on valve seat 1 top under the effect of stage clip 4, thereby realized " 0 " position locking of this mechanism; When needing operating grip 6, if on carry nylon handgrip 8 just moving to drive locking bar 5 compression springs 4 up, thereby realize that release carries out the normal running of valve group.
Claims (3)
1. a hydraulic support is operated valve group enclosed type handle, comprise valve seat, locking bar, stage clip, handle, handgrip, the stepped structure of its inner chamber of described handle, the stepped structure of described locking bar, this locking bar and stage clip all place in the handle, one end of this locking bar is connected with described handgrip, it is characterized in that: the semicircle top of described valve seat is provided with blind hole, and the other end of described locking bar embeds in this blind hole.
