Description

Barrier-free elevator

Technical Field

The utility model discloses an accessible elevator, and relates to the technical field of elevators.

Background

At present, foreign building design is fast forward for research on barrier-free technology, the country is greatly pushing improvement on barrier-free environment, a barrier-free elevator is an important item, and the barrier-free elevator has design standards, such as the opening clear width of an elevator door is not less than 0.80m; the minimum specification of the car is that the depth should not be less than 1.40m and the width should not be less than 1.10m; the medium specification is that the depth should not be less than 1.60m and the width should not be less than 1.40m; armrests with the height of 0.80-0.85m can be arranged on the front and the side surfaces of the lift car; the side surface of the lift car can be provided with a layer selecting button with braille at the height of 0.90-1.10 m; a mirror can be arranged from the position 0.90m higher than the front of the car to the top; the lift car runs up and down and reaches the sound with clear display and layer reporting.

Detailed Description

The utility model is further described below with reference to the drawings and specific examples. Those of ordinary skill in the art will be able to implement the utility model based on these descriptions. In addition, the embodiments of the present utility model referred to in the following description are typically only some, but not all, embodiments of the present utility model. Therefore, all other embodiments, which can be made by one of ordinary skill in the art without undue burden, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

An unobstructed elevator as shown in fig. 1-6, comprising:

a bridge box 1 which can be lifted in an elevator shaft;

the bridge door is connected to the bridge box 1 and ascends and descends along with the car;

landing doors provided at each landing entrance of the elevator shaft;

bridge door sills 2 arranged corresponding to the bridge doors and landing door sills 3 arranged corresponding to the landing doors.

When the bridge carriage 1 stops, a supporting plate 4 and a driving structure for driving the supporting plate 4 to lift in the bridge carriage 1 are arranged below a gap formed by the bridge door sill 2 and the landing door sill 3, namely, after the bridge carriage 1 stops and the bridge door and the landing door are completely opened, the driving structure is triggered, and the driving structure drives the supporting plate 4 to lift to a position horizontal to the bridge door sill 2 and the landing door sill 3, so that wheels are prevented from being blocked in the gap when a wheelchair passes through; before the bridge door and the landing door are closed, the driving structure drives the supporting plate 4 to descend for resetting.

The width of the support plate 4 should in principle be equal to the width of the gap so that the gap can be completely covered, but in view of facilitating the entry of the support plate 4 into the bridge sill 2, the landing sill 3, the support plate 4 and the bridge sill 2, the landing sill 3 may also be a clearance fit, i.e. there may be a certain clearance between the support plate 4 and the bridge sill 2, the landing sill 3, the size of the clearance being so large as not to affect the passage of the wheelchair and/or prevent objects from falling from the gap into the elevator hoistway.

Referring to fig. 1 and 2, in one implementation of the present embodiment, the driving structure includes a linear driver 5 and a guide assembly, the guide assembly is disposed at the bottom of the support plate 4 and perpendicular to the support plate 4, the linear driver 5 is connected to the support plate 4 and is also perpendicular to the support plate 4, and the linear driver 5 outputs power to enable the support plate 4 to vertically lift up and down through the guide of the guide assembly. Such a design allows the support weight of the support plate 4 to be maximized.

The linear actuator 5 may be a cylinder, an electric cylinder, an oil cylinder, or the like. However, in view of cost, it is preferable to use an electric cylinder.

The guiding assembly may be composed of a fixed sliding block 61 and a sliding rail 62 slidably connected to the sliding block 61, and the sliding rail 62 is fixed to the bottom of the supporting plate 4. And a plurality of sliding blocks 61 and sliding rails 62 can be arranged along the length direction of the supporting plate 4 to better support and fix the supporting plate 4.

Referring to fig. 3-6, in another implementation of the present embodiment, the driving structure employs a non-vertical lift, which is specifically composed of a transmission assembly and a rotatable linear driver 5. Since the guide assembly, the linear actuator 5 and the related lines are disposed under the support plate 4 in the vertical lifting driving structure, and the bridge box 1 is crossed with the driving structure in the lifting process, the driving structure cannot protrude the space under the clearance, and the space under the clearance cannot be disturbed to lift the bridge box 1, so that the size of the linear actuator 5 must be small, and the size is generally directly related to the output force of the linear actuator 5, so that the support weight of the support plate 4 is limited. Based on this, the present embodiment provides another driving structure of non-linear elevation, which can obviate the above-mentioned limitation, thereby ensuring sufficient supporting force of the supporting plate 4.

The transmission assembly comprises two symmetrically arranged guide plates 7, a first guide groove 71 and a second guide groove 72 are arranged on the guide plates 7, the first guide groove 71 is vertically arranged, the second guide groove 72 is divided into two sections, one section is vertically arranged, the other section is arranged in an arc line around the lower end of the first guide groove 71, two support rods 8 are arranged on two sides of the support plate 4 corresponding to each guide plate 7, and the two support rods 8 are respectively connected with the first guide groove 71 and the second guide groove 72 in a sliding manner; a transmission rod 9 is arranged between the support rods 8 at the two sides, and the output end of the linear driver 5 is pivoted with the transmission rod 9.

In the driving structure in the embodiment, when the elevator is lifted, the linear driver 5 outputs power, and the supporting plate 4 can be driven to rotate around the lower end of the first guide groove 71 to lift through the transmission rod 9 and the supporting rods 8 on two sides of the supporting plate 4, and then the elevator vertically lifts along the vertical sections of the first guide groove 71 and the second guide groove 72 to reach between the bridge sill 2 and the landing sill 3; when lowering, the support plate 4 is in turn lowered vertically a distance and then rotated and retracted into a space outside the gap. The advantage of this design is that all parts can be retracted to a space outside the gap, so that the lifting of the bridge box 1 is not affected and the supporting force can be ensured by the linear drive 5 with large output force.

Finally, it should be noted that, regardless of the implementation of the driving structure, there are two options for fixing the driving structure, one is fixed at the bottom of the bridge box 1, and only one is needed to be arranged on the driving structure, and the other is fixed in the elevator shaft, but one is needed to be arranged on each floor.

Specifically, in the first embodiment, the slider 61 and the linear actuator 5 may be fixed to the bridge car 1 or may be fixed to the hoistway. In the second embodiment, the guide plate 7 can be selectively fixed on the bridge box 1, can be driven by a straight line to be selectively pivoted on the bridge box 1, and can also be used for digging holes in an elevator shaft, so that the guide plate 7 is fixed in the holes, and can be driven by a straight line to be pivoted in the holes.

The scope of the utility model is not limited thereto and those skilled in the art will appreciate that the utility model includes but is not limited to the drawings and what has been described in the foregoing detailed description. Any modifications which do not depart from the functional and structural principles of the present utility model are intended to be included within the scope of the appended claims.
