Detailed description of the invention
Technical scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the application's protection.
The present embodiment adopts the mode of going forward one by one to write.
Please as shown in Figures 2 to 4, the utility model embodiment provides a kind of protective device, comprises and being arranged in pitch arm 2, and the limiting plate 5 that can rotate with pitch arm 2; Be arranged on the telescoping mechanism 6 on panoramic table 1, telescoping mechanism 6 is provided with extensible member 7, and the direction that extensible member 7 stretches is vertical with pitch arm 2 rotation direction, stopping the state of stretching out that limiting plate 5 rotates and the contraction state that limiting plate 5 can freely rotate to make extensible member 7 tool.
Due to said structure, pitch arm 2 rotates rise under the effect of hoist cylinder 3, when pitch arm 2 turns to duty, switch control rule telescoping mechanism 6 makes extensible member 7 stretch out and is in the state of stretching out, the extensible member 7 stretching out state contacts with limiting plate 5, to limiting plate 5 barrier effects, prevent limiting plate 5 from rotating, because limiting plate 5 is arranged in pitch arm 2, therefore, when carrying out spacing to limiting plate 5, what realize pitch arm 2 is spacing, effectively prevents pitch arm 2 because letting out inefficacy in oil cylinder or driver's cabin 4 is clashed in employee's maloperation.
Protective device also comprises; be arranged on panoramic table 1; changing to make extensible member 7 now to stretch out between state at contraction state for controlling telescoping mechanism 6, controlling time simultaneously also for being at extensible member 7 and stretching out state for realizing hoist cylinder 3 that pitch arm 2 rotates switch 8 out of service.
The protective device that the utility model embodiment provides, in order to the better effects if making extensible member 7 stop limiting plate 5, limiting plate 5 is provided with stopper slot, and when stretching out state to make extensible member 7 be in, extensible member 7 is placed in stopper slot.
Wherein, the telescopic end of telescoping mechanism 6 is provided with pin-and-hole, one end of extensible member 7 is provided with connecting portion, be provided with connecting pin 9 in pin-and-hole, the existing connecting portion of connecting pin 9 connects.
Concrete, the telescopic end of telescoping mechanism 6 is provided with pin-and-hole, arranges a pair engaging lug in one end of extensible member 7, a pair engaging lug is provided with connecting hole, connecting pin 9 realizes the connection of telescoping mechanism 6 and extensible member 7 through connecting hole with pin-and-hole.
Alternatively implementation, pin-and-hole can be arranged on one end that extensible member 7 is connected with telescoping mechanism 6, and engaging lug is arranged on telescoping mechanism 6.
Wherein, telescoping mechanism 6 the present embodiment preferably adopts locating oil cylinder, the excellent employing gag lever post of extensible member 7.
Switch 8 in the present embodiment preferably adopts touching switch.
Before shotcrete vehicle construction, hoist cylinder 3 is packed up, and pitch arm 2 is in nutation state, and pitch arm 2 is to the direction nutation away from driver's cabin 4.When shotcrete vehicle starts to construct, hoist cylinder 3 works, pitch arm 2 is launched, simultaneously, under the effect of panoramic table 1, pitch arm 2 is rotated to driver's cabin 4, when pitch arm 2 is in running order, as shown in Figure 4, when pitch arm 2 is about to be expanded to duty, limiting plate 5 touches switch 8, makes locating oil cylinder play work, is released by gag lever post and is placed in stopper slot, limiting plate 5 is made to hook gag lever post, meanwhile, switch 8 controls hoist cylinder 3 and quits work, state when keeping pitch arm 2 to work.Because limiting plate 5 hooks gag lever post, therefore, effectively prevent and effectively prevent pitch arm 1 because letting out inefficacy or employee's maloperation shock driver's cabin 4 in oil cylinder, improve working security.
