Abstract
The utility model relates to an elevator buffer, in particular to an elevator buffer provided with an air cylinder. The elevator buffer comprises a collision base, a piston, a reset spring, the air cylinder and a fixing base, wherein the collision base is mounted at the top of the piston; the reset spring is mounted on the piston in a sleeving manner; the piston is movably connected with the air cylinder; the air cylinder is fixed on the fixing base. The elevator buffer is characterized by further comprising an outer buffer block and an inner buffer block. According to the utility model, through utilizing the buffer block, the reset spring, a cavity and a damping hole, the kinetic energy obtained during a falling process of a carriage is absorbed and consumed by the buffer block, the reset spring and the air cylinder within reasonable time and motion distance.
Description
Technical field
The utility model relates to a kind of buffer of elevator, particularly a kind of buffer of elevator with cylinder.
Background technology
Buffer of elevator is arranged on elevator hoistways bottom, in the time that lift car fault is fallen, can play last buffering, stop and protective effect, in order to avoid car directly hits at the end.The energy disperser that is applied to now elevator is generally spring and two kinds of structures of hydraulic pressure, and the absorbing impact energy of spring bumper is poor, and bounce is large, easily fractures; Although and water bumper good absorbing effect, complex structure, expensive, need periodical maintenance, and safeguard and maintenance all very inconvenient.
Utility model content
The purpose of this utility model is to overcome existing the problems referred to above in prior art, and a kind of buffer of elevator of simple in structure, good buffer effect is provided.
The utility model solves the problems of the technologies described above adopted technical scheme: this buffer of elevator, comprise head-on collision seat, piston, retracing spring, cylinder and permanent seat, described piston head is provided with head-on collision seat, described retracing spring is sleeved on piston, piston is movably connected on cylinder, cylinder is fixed on permanent seat, it is characterized in that, also include outer bump rubber and interior bump rubber, described outer bump rubber and interior bump rubber are ball-crown body, the shaft section of bump rubber is spherical crown surface, described head-on collision seat top is provided with outer bump rubber, bottom in described cylinder is provided with interior bump rubber, described cylinder and piston forms a cavity, the side of this cavity has damping hole, the aperture of described damping hole is from expanding gradually outside to inside.
As preferably, described piston is provided with seal ring, and described piston is by seal ring and cylinder inner wall close contact.
As preferably, described outer bump rubber and interior bump rubber are polyurethane.
The beneficial effects of the utility model are: by utilizing bump rubber, retracing spring, cavity and damping hole, the fall kinetic energy that obtains in process of car is cushioned piece, retracing spring and cylinder and absorbs and consume in reasonably time and move distance, thereby exempt or alleviated the car injury causing to riding personnel of falling, simultaneously, due to the shock damping action of cavity and damping hole, the elastic potential energy that retracing spring obtains can only slowly discharge, thus the injury of having avoided the quick release of elastic potential energy again to bring to people.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the part sectional view of the utility model embodiment.
Label declaration: hit seat 1, piston 2, retracing spring 3, cylinder 4, permanent seat 5, outer bump rubber 6, interior bump rubber 7, cavity 8, damping hole 9, seal ring 10.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment mono-: referring to Fig. 1 and Fig. 2, this product comprises head-on collision seat 1, piston 2, retracing spring 3, cylinder 4 and permanent seat 5, piston 2 tops are provided with head-on collision seat 1, retracing spring 3 is sleeved on piston 2, piston 2 is movably connected on cylinder 4, cylinder 4 is fixed on permanent seat 5, for further shock absorbing power, this product also includes outer bump rubber 6 and interior bump rubber 7, outer bump rubber 6 and interior bump rubber 7 are ball-crown body, the shaft section of bump rubber is spherical crown surface, head-on collision seat 1 top is provided with outer bump rubber 6, bottom in cylinder 4 is provided with interior bump rubber 7, cylinder 4 forms a cavity 8 with piston 2, the side of this cavity 8 has damping hole 9, the aperture of damping hole 9 is from expanding gradually outside to inside, can make the air of damping hole 9 inner sides easily discharge, and that the cavity in outside enters cavity 8 is comparatively slow, thereby reach the object of slow release retracing spring 3.
In order to ensure the sealing property of cavity 8, piston 2 is provided with seal ring 10, and piston 2 is by seal ring 10 and cylinder 4 inwall close contacts, and outer bump rubber 6 and interior bump rubber 7 are polyurethane.
In actual use procedure, this product is by utilizing bump rubber, retracing spring 3, cavity 8 and damping hole 9, the fall kinetic energy that obtains in process of car is cushioned piece, retracing spring 3 and cylinder 4 and absorbs and consume in reasonably time and move distance, thereby exempt or alleviated the car injury causing to riding personnel of falling, simultaneously, due to the shock damping action of cavity 8 and damping hole 9, the elastic potential energy that retracing spring 3 obtains can only slowly discharge, thus the injury of having avoided the quick release of elastic potential energy again to bring to people.
Above content described in this specification sheets is only to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
