Abstract

The utility model discloses a protection structure of a car platform. The protection structure comprises an adjusting piece which is arranged on a lower car platform in an up-and-down movement mode. The upper position and the lower position of the adjusting piece are adjusted, and so that the top surface of the adjusting piece abuts against the bottom face of an upper car platform. Thus, when the car platform is in an abnormal pressed situation in transportation process, a shock pad can not be deformed and damaged by being stressed with pressure, the deformation of the car platform is avoided, and the levelness of the bottom face of the upper car platform is guaranteed. When the car platform is mounted on site, after the car platform is placed on a lower beam of a car frame, the upper position and the lower position of the adjusting piece are adjusted, and a distance is enabled to be reserved between the top surface of the adjusting piece and the bottom surface of the upper car platform, so that the shock pad can achieve a buffering effect on a platform cage, and the comfort of sitting on the platform cage is guaranteed.

Description

Protection structure at the bottom of a kind of sedan-chair

Technical field

The utility model relates to the protection structure at the bottom of a kind of sedan-chair.

Background technology

In the sedan-chair bottom structure, be arranged at the bottom of the lower sedan-chair by cushion blocking at the bottom of the upper sedan-chair on.Adjust to the right place in factory before dispatching from the factory at the bottom of the sedan-chair, to guarantee the levelness of baseplane at the bottom of the upper sedan-chair.But because cushion blocking is elastomeric material, can be compressed after being under pressure, so at the bottom of the sedan-chair in the process of transportation because the factors such as external force can be out of shape the levelness of baseplane at the bottom of the sedan-chair on the destruction to some extent.

Summary of the invention

The purpose of this utility model provides the protection structure at the bottom of a kind of sedan-chair, can avoid the distortion in transportation at the bottom of the sedan-chair, the levelness of baseplane at the bottom of the sedan-chair in the assurance.

For achieving the above object, the technical solution adopted in the utility model is: the protection structure at the bottom of a kind of sedan-chair, at the bottom of comprising sedan-chair, at the bottom of the lower sedan-chair, at the bottom of the described upper sedan-chair by cushion blocking be arranged at the bottom of the described lower sedan-chair above, protection structure at the bottom of the described sedan-chair also comprises the adjustment part on can being arranged on up or down at the bottom of the described lower sedan-chair, described adjustment part has the first mode of operation and the second mode of operation, when described adjustment part was in the first mode of operation, the end face of this adjustment part was pushed against on the bottom surface at the bottom of the described upper sedan-chair; When described adjustment part is in the second mode of operation, between the bottom surface at the bottom of the end face of this adjustment part and the described upper sedan-chair spacing is arranged.

During implementation, described adjustment part adopts adjusts bolt, is welded with the captive nut for this adjustments bolt screw-in at the bottom of the described lower sedan-chair.

Further, described captive nut be positioned at the bottom of the described lower sedan-chair below, above at the bottom of the described lower sedan-chair, be combined with the nut that can freely tighten on the described adjustment bolt.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages: the levelness of having adjusted bottom surface at the bottom of the sedan-chair before dispatching from the factory at the bottom of the sedan-chair, adjust simultaneously the upper-lower position of adjustment part, so that the end face of adjustment part is pushed against on the bottom surface at the bottom of the sedan-chair, in when, like this situation of improper pressurized occuring in transportation at the bottom of the sedan-chair, cushion blocking can deformation damage not occur because being under pressure, and has avoided the distortion at the bottom of the sedan-chair, has guaranteed the levelness of bottom surface at the bottom of the upper sedan-chair.In the time of at the bottom of at the scene sedan-chair being installed, after being placed on the car frame underbeam at the bottom of the sedan-chair, adjust the upper-lower position of adjustment part, so that between the bottom surface at the bottom of the end face of adjustment part and the upper sedan-chair spacing is arranged, cushion blocking can play buffer action to car like this, guarantees the traveling comfort that car is taken.

Description of drawings

Accompanying drawing 1 is scheme drawing one of the present utility model, and the end face of wherein adjusting bolt is pushed against on the bottom surface at the bottom of the sedan-chair;

Accompanying drawing 2 is scheme drawing two of the present utility model, and wherein adjusting between the end face of bolt and the bottom surface at the bottom of the upper sedan-chair has spacing.

The specific embodiment

Further set forth structure of the present utility model below in conjunction with accompanying drawing.

Shown in Fig. 1-2; protection structure at the bottom of a kind of sedan-chair; comprise at the bottom of the sedan-chair 1; at the bottom of the lower sedan-chair 2; can be arranged on up or down at the bottom of the lower sedan-chair adjustment part 4 on 2; in the present embodiment; adjustment part 4 adopts adjusts bolt; be welded with the captive nut 5 for these adjustments bolt 4 screw-ins at the bottom of the lower sedan-chair on 2; the turn adjustment part 4 like this; realize the adjusting of the upper-lower position of adjustment part 4, captive nut 5 be positioned at the bottom of the lower sedan-chair 2 below, adjust on the bolt 4 at the bottom of the lower sedan-chair 2 above be combined with the nut 5 that can freely tighten; like this after adjusting adjustment part 4 puts in place; by two nuts 5, realize that adjustment part 4 is in the stable position on 2 at the bottom of the lower sedan-chair, such as Fig. 1-2.

At the bottom of the upper sedan-chair 1 by cushion blocking 3 be arranged at the bottom of the lower sedan-chair 2 above, cushion blocking 3 adopts rubber pads, and car is played buffer action.The levelness of 1 bottom surface at the bottom of the sedan-chair on before dispatching from the factory at the bottom of the sedan-chair, having adjusted, adjust simultaneously the upper-lower position of adjustment part 4, so that the end face of adjustment part 4 is pushed against at the bottom of the sedan-chair on 1 the bottom surface, as shown in Figure 1, in when, like this situation of improper pressurized occuring in transportation at the bottom of the sedan-chair, cushion blocking 3 can deformation damage not occur because being under pressure, and has avoided the distortion at the bottom of the sedan-chair, has guaranteed the levelness of bottom surface at the bottom of the upper sedan-chair.In the time of at the bottom of sedan-chair is installed at the scene, after being placed on the car frame underbeam at the bottom of the sedan-chair, adjust the upper-lower position of adjustment part 4, so that between 1 the bottom surface spacing L is arranged at the bottom of the end face of adjustment part 4 and the upper sedan-chair, as shown in Figure 2, so just can further adjust and install at the bottom of the sedan-chair.The size of spacing L is relevant with the hardness of Rubber shock-absorbing pad 3, the deflection that allows during also from the elevator design of different load-carryings, friction speed is relevant, the maximum deformation quantity that L allows in the time of should being less than or equal to design fully guarantees the comfort level of lift car when operation.
