The beneficial effects of the utility model: the elevator of submissive cushion effect of the present utility model, adopt the structure that recoil spring combines with damper assembly, and damper assembly gets involved damping in recoil spring compression process, form the buffer damping mode of going forward one by one, touch dumping force in bottom buffering process at elevator car to increase gradually, and increase process is mild rapidly compared with common spring, final stage forms buffer damping, realize the ride comfort of downstream buffer and there is enough dumping forces, therefore the damping process of cushion stroke and laddering gradual change can compared with prior art be increased, the spring that elasticity modulus is less can be adopted in scheme, the damping in later stage gets involved the elastic buffer combining early stage, be applicable to express elevator use, there is the effect of dynamic application at any time, before making elevator car touch the end and the traveling comfort of moment of contact Buffer Unit and reliability effectively improve, the safety performance of hoisting elevator.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: the elevator of the submissive cushion effect of the present embodiment, comprise elevator car 1 and buffering assembly, described buffering assembly comprises and being fixedly installed on bottom elevator for preventing elevator car 1 rigid touch bottom buffering assembly and form the damper assembly of damping to elevator car in Buffer Unit being by elevator car elastic compression process, when Buffer Unit is compressed to necessarily (setting) degree, damper assembly generation shock damping action, forms the buffer damping effect of going forward one by one.
In the present embodiment, described Buffer Unit comprises the dash plate 13 being arranged at recoil spring on basis 3 and being supported in recoil spring 3 top, and described dash plate 13 is just to bottom elevator car 1; Basis 8 refers to the basis of the installation into Buffer Unit; As shown in the figure, basis being also provided with the spring perch 6 for installing recoil spring 3, can be used for maximum compression stroke and the limited compression position of regulating spring 3; The quantity of recoil spring 3 can be installed as required, is generally more than three along the circumferential direction uniform settings; Dash plate 13 can adopt guidepost to install with recoil spring 3 top to coordinate and weld, and avoids departing from when buffering or bounce-back.
In the present embodiment, the piston rod 5 that described damper assembly comprises cylinder body 9, damping piston 10 and is fixedly connected with damping piston 10, described piston rod 5 recoil spring 3 by dash plate 13 by elevator car 1 compression process in engage with dash plate 13, form damping by damping piston 10 pairs of dash plates; In the utility model, before recoil spring 3 is compressed and is not reached compression limit, the piston rod 5 of damper assembly is depressed row, damping piston 10 is had an effect formation damping, jointly buffer damping is formed with recoil spring, the mode that piston rod 5 engages with dash plate is generally the way of contact, and namely the descending direct contact piston bar upper end of dash plate, can realize the effect of descending damping; As shown in the figure, damping piston 10 has damping hole (setting size and number as required), be full of the damping liquid such as fluid or magnetic flow liquid in cylinder body, when piston moves under external force, damping liquid passes through by means of only damping hole, forms damping; As shown in the figure, cylinder body 9 is embedded among basis 8, and top is sealed by cylinder cap 11, and cylinder cap 11 is sealedly attached to cylinder body 9 by the holding-down bolt 7 be embedded on basis 8, cylinder cap 11 is integrally formed the axle sleeve 12 for leading to piston rod; Adopt the structure that recoil spring combines with damper assembly, touch damper assembly in bottom buffering process at elevator car and engage the effect playing laddering buffer damping, this structure can increase the cushion stroke of Buffer Unit and reduce the elastic coefficient, the realization that can more relax whole process buffering; This structure is suitable for all cage type elevators and uses, and when elevator accident touches the end, can ensure that compression that is mild, that go forward one by one gradually cushions.
In the present embodiment, described recoil spring 3 is variable-pitch spring, touch dumping force in bottom buffering process at elevator car to increase gradually, and increase process is mild rapidly compared with common spring, realize the ride comfort of downstream buffer and there is enough dumping forces, therefore the elasticity modulus of cushion stroke and gradual change can compared with prior art be increased, the technical scheme of this critical performance parameters of automatic adjustment spring power can be formed, be applicable to express elevator to use, there is the effect of dynamic application at any time, in conjunction with the damping structure that go forward one by one relative to recoil spring, before making elevator car 1 touch the end and the traveling comfort of moment of contact Buffer Unit and reliability effectively improve, the safety performance of hoisting elevator.
In the present embodiment, the pitch of described recoil spring 3 becomes large from bottom to top gradually; The moment that can contact at elevator car 1 can submissive buffering at once, and increases elasticity modulus gradually.
In the present embodiment, relatively with piston rod 5 to be provided with on described dash plate 13 so that axially directed mode the orienting sleeve 4 of piston rod 5 can be coated at, to be provided with in described orienting sleeve 4 for the pedestal 2 with piston rod 5 tip contact; Adopt orienting sleeve 4 structure, the lateral orientation of dash plate 13 and piston rod 5 can be limited, thus realize the damping of actv. joint.
In the present embodiment, described pedestal 2 is integrally formed and be fixedly installed on dash plate 13 with orienting sleeve 4, and dash plate 13 thickeies process for being fixedly installed pedestal place; As shown in the figure, by the downward forming station hierarchic structure of dash plate, be followed successively by thickening layer, pedestal 2 and orienting sleeve 4, form stable load basis according to the force structure of damping, thus ensure the safety in buffer damping process further.
In the present embodiment, described dash plate 13 upper surface, piston rod 5 upper surface and pedestal 2 lower surface all arrange cushion layer; This cushion layer can prevent direct rigid contact, thus ensures safety and compliance.
In the present embodiment, described recoil spring 3 is installed on basis by the spring perch 6 be fixed on basis 8, ensures that the installation strength of spring also can change the height of spring perch as required, reaches the object of adjustment its length, thus adjustment compression stroke.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
