Abstract
The utility model discloses the mechanism that prevents from by mistake stepping on pilot valve for a kind of hydraulic self-traveling mobile power station, comprise pedal assembly (1), hinge (2), fixed head (3), the two ends of pedal assembly (1) and hinge (2) are weldingly fixed on respectively the side of pilot valve pedal (6), the width of described pedal assembly (1) is not less than two pilot valve pedals (6) width in the horizontal direction, and described pedal assembly (1) also comprises the projection (5) that can withstand operating grip (7) under the state that puts down pedal assembly (1).After hinge (2) is opened, it is upper that pedal assembly (1) drops on pilot valve pedal (6), thereby stoped moving up and down of pilot valve pedal (6) two ends, thereby realized the fixedly effect of pilot valve pedal (6).Adopt a utility model just can limit the movement of two pilot valve pedals and operating grip simultaneously, prevent maloperation, improve safety, cost-saving.
Description
Technical field
The utility model relates to the mechanism that prevents from by mistake stepping on pilot valve for a kind of hydraulic self-traveling mobile power station.
Background technology
At present, can be used for the pilot valve of the attached facility of two-way control hydraulic pressure comprises two pedals, its two ends all can knee-action, in the situation that not using the attached facility of hydraulic pressure, when operator is when operating other actions of mobile power station, exist and step on the risk that plate is opened hydraulic moving oil circuit by mistake, damage banked direction control valves; In addition,, if when carrying out other actions of mobile power station, mistake pulling process handle also easily causes personal injury and property loss.
On April 17th, 2013, the Chinese utility model patent manual of bulletin disclosed a kind of " device that prevents from by mistake stepping on pilot valve for excavator " (application number CN201220548126.9 that our company applies for, notification number CN202882010U), this device comprises fixed head, hinge and pedal assembly, and pilot valve pedal and operating grip, hinge one end is connected with fixed head, and the other end of hinge is connected with pedal assembly.In use find, for the mobile power station of two pilot valves, need left and right that two these devices are set, and this installs under closure state effectively fixing operation handle.
Summary of the invention
The purpose of this utility model is to provide a kind of Wu Ta of preventing mechanism, by the use of this mechanism, the two ends of pilot valve can be fixed, stop moving forward and backward of operating grip simultaneously, thereby avoid when not using the attached facility of hydraulic pressure because step on banked direction control valves is caused damage by mistake, and touch the error job that operating grip produces by mistake.
To achieve these goals, the utility model adopts following technical scheme: the mechanism that prevents from by mistake stepping on pilot valve for a kind of hydraulic self-traveling mobile power station, comprise hinge, fixed head and pedal assembly, and pilot valve pedal and operating grip, weld respectively at the two ends of fixed head and pedal assembly and hinge, be fixed on the side of pilot valve pedal, the width of pedal assembly is not less than two pilot valves width in the horizontal direction, and pedal assembly also comprises that is being put down the projection that can withstand operating grip under the state of pedal assembly.
After hinge is opened, pedal assembly drops on two pilot valve pedals, thereby has stoped moving up and down of two pilot valve pedal two ends, and pedal assembly plays the object of restriction operating grip motion in the projection of operating grip direction.Compared with prior art, adopt this device just can limit the movement of two pilot valve pedals and operating grip simultaneously, prevent maloperation, improve safety, cost-saving.

In figure: 1. pedal assembly, 2. hinge, 3. fixed head, 4. projection, 5. cavity, 6. pilot valve pedal, 7. operating grip.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Shown in Fig. 1 is that the utility model is arranged on the structural representation under open mode on mobile power station, the mechanism that prevents from by mistake stepping on pilot valve for a kind of hydraulic self-traveling mobile power station, comprise pedal assembly 1, hinge 2, fixed head 3, pilot valve pedal 6 and operating grip 7, fixed head 3 and pedal assembly 1 weld respectively with the two ends of hinge 2, be fixed on the side of pilot valve pedal 6, the width of described pedal assembly 1 is not less than two pilot valve pedals 6 width in the horizontal direction, described pedal assembly 1 also comprises the projection 5 that can withstand operating grip 7 under the state that puts down pedal assembly 1.When not using the attached facility of bidirectional hydraulic, the anti-error hinge 2 of stepping on mechanism to be opened, pedal assembly 1 is started, and drops on pilot valve pedal 6.While at this moment applying active force toward pilot valve pedal 6 two ends again, because pedal assembly 1 two ends can not move up and down, thereby stop moving up and down of pilot valve pedal 6, therefore played anti-error function of stepping on.The projection 4 of pedal assembly 1 is withstood operating grip 7, has limited its movement, thereby prevents the work accident that maloperation causes.
Fig. 2 is that the utility model is arranged on the structural representation under open mode on mobile power station.When using the attached facility of bidirectional hydraulic, the anti-error hinge 2 of stepping on mechanism is folded, pedal assembly 1 leaves pilot valve pedal 6.At this moment pin is placed on pilot valve pedal 6, toward arrow indicated direction, applies active force, and pilot valve pedal 6 will move to arrow indicated direction, thereby opens the oil circuit of the attached facility of hydraulic pressure.
Fig. 3 is STRUCTURE DECOMPOSITION figure of the present utility model, preferred, digs out cavity 5 in the projection 4 of pedal assembly 1, has not only alleviated weight but also do not affect mechanical strength.The middle part of pedal assembly 1 can arrange a plurality of empty 5, has both alleviated weight, and the silt of sole can have been leaked down, and guarantees the clean of working space.
Fig. 4 is the structural representation of the utility model under open mode, that is: folding hinge 2, and pedal assembly 1 is removed from pilot valve pedal 6 tops.
Fig. 5 is the structural representation of the utility model under closure state, that is: hinge-opening 2, and pedal assembly 1 is turned on pilot valve pedal 6.
To sum up, adopt a utility model just can limit the movement of two pilot valve pedals 6 and operating grip 7 simultaneously, prevent maloperation, improve safety, cost-saving.
