Description

A kind of elevator car frame

Technical field

The utility model belongs to lift appliance field, and in particular to a kind of elevator car frame.

Background technology

The sedan-chair frame of elevator is the bearing structure of car, and for car inside sedan-chair frame, the load of car is delivered to traction by it Steel wire rope, buffer is generally provided with the bottom of elevator, buffer is last link of elevator safety system, in elevator Play a part of buffering when failure or accident crouching bottom, so as to alleviate the people in elevator or elevator from directly hitting, In buffering course, the bottom of sedan-chair frame directly contacts with buffer, but the bottom of existing sedan-chair frame rarely has setting buffer unit, certain Buffering effect is reduced in degree, therefore the injury to elevator or people can be increased in buffering course.

A kind of small elevator car frame damping (Application No. 201621030297.7) of patent, include sedan-chair and erect post, delay Rush rubber, pressing plate, adhesive foam bar, buffer beam, beam etc.；Be arranged with buffer beam on sedan-chair frame upper beam, two buffer beams it Between be provided with rope sheave seat, be provided with beam between buffer beam and sedan-chair frame upper beam, sedan-chair erects the post side relative with car lateral surface and set There is adhesive foam bar, pressing plate is bolted in the car top of car.Although the utility model has damping, buffering effect, car floor is reduced Thickness, but the utility model enters row buffering using yielding rubber and cushion pad, and damping, buffering is ineffective.

Utility model content

In view of above-mentioned deficiency, the purpose of this utility model provides a kind of elevator car frame, has good damping, buffering effect, The injury to elevator or personnel during elevator cushion can be reduced.

The utility model provides following technical scheme：

A kind of elevator car frame, including main support, the bottom of the main support are provided with car floor, and the lower section of the car floor, which is provided with, delays Layer is rushed, the first buffer and the second buffer, the car floor and the cushion are provided between the car floor and the cushion Connected by the first buffer, second buffer above the cushion, and the upper end of second buffer with It is remaining between the car floor to have gap.

Preferably, the cushion is rectangular-shape, and first buffer is located at four right-angle positions of the cushion Put, the middle part of the cushion is provided with the second buffer.

Preferably, first buffer and second buffer use hydraulic damper.

Preferably, the resistance of second buffer is more than the resistance of first buffer.

Preferably, the both sides of the car floor are provided with oblique pull beam, and one end of the oblique pull beam connects with the car floor, described oblique The other end of straining beam connects with main support.

Preferably, the oblique pull beam uses Q235B steel, and Q235B steel strengths, plasticity and welding performance are good, and cost It is low.

The beneficial effects of the utility model：

Cushion bottom of the present utility model is impacted, and the first buffer can once be buffered to car floor, and second is slow Secondary buffer can be carried out to car floor by rushing device, and buffering and damping effect is substantially increased by level 2 buffering, so as to reduce elevator meaning The outer injury fallen to elevator or personnel.

Brief description of the drawings

Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：

Fig. 1 is the utility model front view；

Fig. 2 is car floor and cushion sectional view.

In figure mark for：1st, main support；2nd, car floor；3rd, cushion；4th, the first buffer；5th, the second buffer；6th, oblique pull Beam.

Embodiment

As depicted in figs. 1 and 2, a kind of elevator car frame, including main support 1, the bottom of main support 1 are provided with car floor 2, car floor 2 Lower section be provided with cushion 3, be provided with the first buffer 4 and the second buffer 5 between car floor 2 and cushion 3, car floor 2 and buffering Layer 3 is connected by the first buffer 4, and the second buffer 4 is above cushion 3, and the upper end of the second buffer 4 and car floor 2 Between remaining have gap；Elevator accidental falling, the bottom of cushion 3 are impacted, and the first buffer 4 can be carried out once to car floor 2 Buffering, the second buffer 5 can carry out secondary buffer to car floor 2, buffering and damping effect substantially increased by level 2 buffering, so as to Reduce injury of the elevator accidental falling to elevator or personnel.

As depicted in figs. 1 and 2, cushion 3 is rectangular-shape, and the first buffer 4 is located at four square positions of cushion 3 On, the middle part of cushion 3 is provided with the second buffer 5, and this arrangement can ensure that the steady of cushion 3 in buffering course；The The resistance of two buffers 5 is more than the resistance of the first buffer 4, and excessive impulsive force can be entered row buffering by such second buffer, Prevent excessive impulsive force from causing the first buffer to damage；First buffer 4 and the second buffer 5 use hydraulic damper, liquid Press damper not small only in response to fast, frictional resistance and service life is grown.

As depicted in figs. 1 and 2, the both sides of car floor 2 are provided with oblique pull beam 6, and one end of oblique pull beam 6 connects with car floor 2, oblique pull beam 6 other end connects with main support 1；Oblique pull beam 6 can ensure that the steady of car floor 2；Oblique pull beam 6 uses Q235B steel, Q235B steel Material intensity, plasticity and welding performance are good, and cost is low.

Utility model works mode：

As depicted in figs. 1 and 2, when elevator accidental falling, the bottom of cushion 3 are impacted, the first buffer 4 can be to sedan-chair Bottom 2 is once buffered, and the second buffer 5 can carry out secondary buffer to car floor 2, substantially increase buffering by level 2 buffering and subtract Effect is shaken, so as to reduce injury of the elevator accidental falling to elevator or personnel.

Preferred embodiment of the present utility model is these are only, is not limited to the utility model, although with reference to before State embodiment the utility model is described in detail, for those skilled in the art, it still can be to preceding State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic.It is all this Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in Protection domain within.
