Abstract
The utility model relates to a frustum bottom shocking absorber of an elevator which is installed on the shocking absorber of an original bottom pit machine. The utility model is composed of an upper circular steel plate, a lower circular steel plate and three circular honeycomb briquette rubber blocks in the middle of the circular steel plates, wherein each circular rubber block is provided with nine through holes, the through holes of the three rubber blocks are communicated up and down, each through hole is provided with a spring, the lowest rubber block is provided with an air-bleed hole, the bottom surface of the utility model is fixedly connected with the shocking absorber of the original machine by a steel jacket, and the upper steel plate is adhered with a rubber layer. When an elevator safety system fails and a cage falls, the bottom steel plate of the cage crashes the utility model, the upper steel plate is compressed downwards, and the good elasticity of the rubber, air in the holes, and springs in the through holes are used for landing the cage softly.
Description
The utility model relates to a kind of elevator car safety, particularly elevator pier bottom buffering device.
Along with the fast development of China's skyscraper, elevator more and more is widely used as the actv. means of delivery.But the elevator safety accident happens occasionally in recent years; its major cause is that existing elevator end of a year or month buffer design is unreasonable; original elevator end of a year or month shock absorber is arranged on the mechanical damping device of pit; in case the safety system of elevator is malfunctioning; cab just falls at a high speed and energy disperser forms mechanical collision; the cushioning effect of this energy disperser is very limited, can not play the effect of actv. safety guard-safeguard.
Order of the present utility model is a kind of elevator pier bottom buffering device, and it can make cab form soft landing when elevator safety system is malfunctioning, prevents the generation of bump accident.
The purpose of this utility model is to realize like this, on the former slow device of elevator pit, increase a cover safety device, circular steel plate at first, bottom is welded with one of round steel bushing, be connected with former energy disperser and fixing, the steel plate top is provided with the high elastic rubber piece of 3 round and the same diameters of steel plate.Every block of rubber is provided with nine through holes, the centre is a macropore, be eight equal portions of aperture on every side, 3 blocks of rubber, align installation (with the honeycomb briquette shape approximation) between the Kong Yukong, link into an integrated entity with glue, be provided with in each hole from top to bottom spring each one, and then bind after connecting with glue by a block plate, steel plate upwards one side posts one of round rubber pad, prevents from directly to bump with the cab metal, when feeling at ease, elevator at first contacts like this with loam cake, loam cake pushes downwards, utilizes the favorable elasticity of hollow blob of viscose to be the master, and air in the hole and spring are auxilliary, realize the soft landing of cab, avoid the generation of bump accident.
The utility model is simple in structure, good damping result, simple installation, can with the supporting use of former buffer of elevator, can improve the safety performance of elevator greatly.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
The utility model comprises that round rubber pad 1 is fixed on the loam cake outside.Circular steel plate loam cake 2 binds.Circular nine hole rubber blocks 3.(on the figure for partly cuing open) circular nine hole rubber blocks 4, circular nine hole rubber blocks 5 (annotate the 3,4, the 5th, the rubber block of same shape, want during installation to amplexiform after the hole aligns up and down), air bleed hole 6 during extruding, the steel bushing 8 that circular base seat steel plate 7 and former energy disperser fix, air bleed hole 9 in the blob of viscose during circular hole extruding is provided with spring 10 in the hole, spring is to connect down to connect on the end seat 7 to cover the original energy disperser 11 of 2 pits.
Claims (3)
1, this elevator pier bottom buffering device, it is characterized in that a circular steel plate, bottom is welded with that one of round steel bushing is connected with former energy disperser and is fixing, the steel plate top is provided with 3 blocks of round and every block of rubber of the high elastic rubber piece same diameter of steel plate and is provided with nine through holes, middle macropore, eight equal portions of aperture on every side align installation between 3 rubber holes and the hole, respectively establish a spring in the hole and then connect with glue by a block plate after bind.
