Description
Technical Field
The utility model relates to a lift platform field, in detail say an X type lift platform anti-falling device.
Background
It is known that X lift platform overhauls at the high altitude, cargo handling and auto repair field all have extensive application, increase along with the number of times of use, maintain improper and quality scheduling problem, thereby X type lift platform breaks down very easily in the course of the work, great increase operating personnel's danger coefficient like this, cause unnecessary personal and property loss, influence work efficiency, the X type lift platform anti-falling system of present stage all can't the direct action in lifting support, the complicated manufacturing cost of structure is high, perhaps need the people to get into the platform below, there is certain potential safety hazard.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a X type lift platform anti-falling device to cause when solving X type lift platform and fall and ordinary anti-falling device structure complicacy when breaking down, it is with high costs, need the manual operation have certain potential safety hazard scheduling problem.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a X type lift platform dropproof device, be equipped with the lift platform roof, X type lifting support is installed to its characterized in that lift platform roof lower extreme, X type lifting support lower extreme is connected with the lift platform chassis, X type lifting support middle part is equipped with the lift platform entablature, the lower part is close to lift platform chassis department and is equipped with the lift platform bottom end rail, lift platform hydraulic cylinder both ends are connected with lift platform entablature and lift platform bottom end rail respectively, the inboard fixed free bearing of lift platform chassis, the support low side that prevents falling articulates on the free bearing, the support top of preventing falling is installed U type recess buckle, the support middle-end processing of preventing falling has bellied trapezoidal rail, the support lower extreme that prevents falling is installed and is prevented falling and drive actuating cylinder and solenoid valve, be equipped with the telescopic link in the drive actuating cylinder that prevents falling, the metal roller.
The beneficial effects of the utility model are that, utilize X type lift platform dropproof device, can effectually prevent that lift platform from falling the person and the loss of property that cause, the simple operation simple structure, low in manufacturing cost has improved security and availability factor greatly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, a lifting platform hydraulic oil cylinder, 2, a lifting platform upper cross beam, 3, a lifting platform lower cross beam, 4, an anti-falling support, 5, an anti-falling driving air cylinder, 6, a metal roller, 7, an electromagnetic valve, 8, a control switch, 9, a hinged support, 10, a lifting platform underframe, 11, a telescopic rod, 12, a lifting platform top plate, 13, an X-shaped lifting support, 14, a U-shaped groove buckle and 15, a trapezoidal rail are arranged.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, a lifting platform top plate 12 is provided, an X-shaped lifting support 13 is installed at the lower end of the lifting platform top plate 12, the lower end of the X-shaped lifting support 13 is hinged to a lifting platform underframe 10, a lifting platform upper cross beam 2 is arranged at the middle of the X-shaped lifting support 13, a lifting platform lower cross beam 3 is arranged at the lower part close to the lifting platform underframe 10, two ends of a lifting platform hydraulic oil cylinder 1 are hinged to the lifting platform upper cross beam 2 and the lifting platform lower cross beam 3 respectively, a hinged support 9 is fixed on the inner side of the lifting platform underframe 10, the lower end of a falling prevention support 4 is hinged to the hinged support 9, a U-shaped groove buckle 14 is installed at the top of the falling prevention support 4, a raised trapezoidal rail 15 is processed at the middle end of the falling prevention support 4, a falling prevention driving cylinder 5 and an electromagnetic valve 7 are installed at the lower end of the.
When the utility model is used, the lifting platform hydraulic oil cylinder 1 extends the X-shaped lifting support 13 by pushing the upper lifting platform crossbeam 2 and the lower lifting platform crossbeam 3, so as to send the lifting platform top plate 12 to the height required by the work, the anti-falling device control switch 8 is operated, so that the control electromagnetic valve 7 extends the telescopic rod 11 in the anti-falling driving cylinder 5, the telescopic rod 11 pushes the metal roller 6 to move along the inclined plane of the trapezoidal rail 15 to reach the top end of the trapezoidal rail 15, so that the anti-falling support 4 is lifted, when the telescopic rod 11 in the anti-falling driving cylinder 5 is completely extended, the anti-falling support 4 drives the top U-shaped groove buckle 14 to rise to the position of the lower lifting platform crossbeam 3, the U-shaped groove buckle 14 is tightly clamped with the lower lifting platform crossbeam 3, when the lifting platform falls, the telescopic rod 11 connected with the metal roller 6 and the anti-, make metal roll 6 unable motion because U type recess buckle 14 and lifting platform bottom end rail 3 chucking to form self-locking function, and then prevented falling of X type lifting platform.
