Description

A kind of gate safety guard

Technical field

The utility model relates to a kind of safety guard that is used on the Power-driven gate.

Background technology

At present, generally be provided with guardroom or reception room at company or factory building and outside separated place, in the guardroom or the outside in reception room be provided with the gate, in order to control with control vehicle or personnel's turnover.The gate is made of metal, and comes transmission by motor by dependency structures such as chains, and the gate can be moved laterally, thereby reaches the purpose that the control gate is opened or closed.But above-mentioned gate is when reality is used, but exist following shortcoming: at the gate laterally in the process of pulling as when running into vehicle or personnel, because of motor can not shut down, the gate still ceaselessly advances, can make the gate bump against vehicle or personnel because of moving on like this, thereby may cause damaged vehicle and injury to personnel.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of gate safety guard; make the gate in drawing process, run into vehicle or personnel Shi Ke and cut off motor power by this safety guard; thereby can not cause damaged vehicle or injury to personnel, improve the fail safe at gate.

For solving the problems of the technologies described above, a kind of gate of the utility model safety guard comprises a base, a pedestal and a motor, on pedestal, be provided with two shaft seats, between two shaft seats, be provided with a rotating shaft, end part interval in rotating shaft has protruded out inboard sprocket wheel and outside sprocket wheel, the side chain wheel is gone up a meshing chain outside, and the two ends of this chain are fixedly arranged on the drive chain case; On pedestal, be provided with two bracing frames in addition, be respectively equipped with an axle bed on each bracing frame, be provided with an axostylus axostyle between two axle beds, on axostylus axostyle, be provided with a connecting rod, this connecting rod top is provided with a motor base plate, is provided with the motor seat on motor base plate, and motor is fixed on the motor seat, extension is provided with a sprocket wheel on the motor, is arranged with chain between this sprocket wheel and above-mentioned inboard sprocket wheel; Level is to being provided with two switches on the bracing frame, locating to be installed with respectively a hollow form sleeve above with respect to two switches on the bracing frame, and an actuating strut penetrates in this sleeve, and the top of actuating strut passes from the top of sleeve, an outside sheathed spring of actuating strut in the sleeve; One adjusts screw is screwed together in the cover tube bottom, adjusts the bottom of the top ejection of screw to above-mentioned spring, in the central authorities that adjust screw one through hole is arranged, and actuating strut is stretched through out down by this through hole and is positioned at the place, summary top of above-mentioned switch.

Above-mentioned a kind of gate safety guard is respectively equipped with a control lever on described each switch.

Above-mentioned a kind of gate safety guard has a catch on described actuating strut, this catch is positioned at the top medial surface of sleeve.

Owing to adopted above-mentioned technical pattern, with the base setting on the ground, drive chain case is in order to drive the gate during use.When vehicle or personnel are run in the gate in laterally moving, drive chain case shakes because of being subjected to hindering, related its interior chain that makes also shakes, will make sprocket wheel and the chain on this sprocket wheel on the motor can't be smooth and easy when transmission like this, and then make motor base plate, axostylus axostyle and connecting rod generation beat, even also motor base plate presses down actuating strut, actuating strut ejection down is to switch, make switch will control the dump of revolution, thereby motor is no longer remained in operation, so can prevent to bump against vehicle or personnel because of the gate continues to move, improved the fail safe at gate, prevented the generation of accident effectively.
