Description

Technical Field

[0001] The invention relates to an improvement of an elevator structure, in particular to an aluminum alloy structure elevator car without an elevator door. Background Art

[0002] Elevators have various structural forms, and with the development of the market, they are increasingly used in small buildings, such as low-rise buildings such as villas. In such usage scenarios, the load requirements of the elevator are low, the number of passengers is small, and the space reserved in the elevator shaft is not large. Therefore, small elevators are mostly used. Elevators are required to be lightweight and easy to use. Conventional elevators have structures such as floor doors and car doors, which occupy a large space between the two doors, reducing the available space of the elevator car. Therefore, it is necessary to provide a car structure with a reduced door structure to achieve the purpose of lightweight. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a doorless aluminum alloy structure elevator.

[0004] The technical solution adopted by the present invention to solve the above problems is: the car includes a car bottom structure, an aluminum alloy frame structure, a ceiling and a car wall. The car bottom structure serves as the bottom support structure of the car to form a horizontal spatial ground structure. The aluminum alloy frame structure is fixed on the car bottom structure to form a cubic frame structure. The ceiling is fixed on the top plane of the aluminum alloy frame structure. The car wall is fixed on the side elevation of the aluminum alloy frame that needs to be closed. The unclosed side elevation serves as a passage for entering and exiting the car space. The car adopts a car space structure formed by a stable car bottom structure and an aluminum alloy frame. The overall structure is lightweight and can be assembled as needed. The door opening direction and the fixed installation direction of the car can be set to meet the requirements of different installation spaces.

[0005] Furthermore, the car bottom structure includes a base surface structure and a car bottom connection back frame. The base surface structure is the ground foundation structure of the car space. The car bottom connection back frame is fixedly connected to the base surface structure and forms an upright connection surface on the back outer side of the car. The car bottom connection back frame is connected to the car frame. The base surface structure is mainly the spatial ground structure of the car, providing a ground foundation. The car bottom connection back frame is a structure connected to the car frame. The car frame is an external fixed frame structure of the car. The structure that drives the car to move is mainly connected to the car frame. The lateral installation strength of the car bottom connection back is high, which can ensure the structural strength of the car and save elevator shaft space.

[0006] Furthermore, the basic surface structure includes a car floor, bottom reinforcement ribs, side reinforcement ribs and an external cladding plate. The car floor is a basic plane plate structure of the floor of the car space. A plurality of parallel bottom reinforcement ribs are welded to the bottom of the car floor. The back side of the car floor is connected to the car floor connecting back frame. The other sides are fixed with side reinforcement ribs. The external cladding plate is fixed on the sides and bottom of the combination of the car floor, bottom reinforcement ribs and side reinforcement ribs. The car floor is the main plane basic structure, which is reinforced by a plurality of reinforcement rib structures. At the same time, for the sake of beauty, the reinforcement ribs and other structures are surrounded by external cladding plates, which also has the function of preventing debris from entering.

[0007] Furthermore, the external covering plate includes a side covering plate and a bottom covering plate, and a floor panel is laid on the car floor. The side covering plate forms a slot structure surrounded on three sides, and is inserted to surround the outer side of the side reinforcement ribs and the edge of the car floor of the floor panel. The bottom covering plate is evenly covered on the bottom of the basic surface structure and covers the surface of the bottom of the car floor. The side covering plate also has the function of fixing and combining the floor panel with the car floor. The floor panel can be made of PVC floor or other material. The bottom covering plate seals the car floor surface and can be filled with sound insulation material. The bottom covering plate has the function of sealing the sound insulation material.

[0008] Furthermore, the car bottom connecting back frame includes a right-angle bracket and a connecting back plate. The right-angle bracket forms a right-angle steel frame structure. The right-angle bracket is formed by welding steel. The right-angle part on one side is horizontally inserted into the base surface structure, and the right-angle part on the other side is vertically arranged, and the connecting back plate is fixed thereon. The connecting back plate is also fixed to the aluminum alloy frame structure. The right-angle bracket is a right-angled structural support component, which is effectively fixed and combined with the lower structure of the car bottom plate. The basic strength of the structure is high, which can provide effective support for the car. The connecting back plate has a large area and good connection reliability. The connecting back plate can also be set on the upper part of the car to play a balancing role. The upper connecting back plate can be connected to the aluminum alloy frame structure.

[0009] Furthermore, the aluminum alloy frame structure includes a front column profile, a rear column profile, a ceiling frame profile, a car wall frame profile and a light curtain bracket profile, the front column profile is fixed to the front corner of the car, the rear column profile is fixed to the back corner of the car, the front column profile and the rear column profile form an upright support frame of the car, the ceiling frame profile is fixed to the top of the front column profile and the rear column profile, the car wall frame profile is fixed between the front column profile and the rear column profile on one side, and is fixedly connected to the edge of the ceiling frame profile at the same time, and the light curtain bracket profile is fixed to the side of the front column profile or the rear column profile on the door opening side of the car. The spatial structure of the car is composed of aluminum alloy profiles, and the overall structure can be greatly reduced. Since it is a doorless structure, the light curtain is used as the basis for safe operation. The light curtain is fixed with a separate fixed profile to ensure the accuracy of the light curtain's judgment. The profile mainly provides a frame structure. The car walls and ceiling can be covered with plexiglass sheets or other similar types of panels, which can effectively control the overall weight.

[0010] Furthermore, the front column profile is formed into a cross-section angle structure, which has two connection slots, which are arranged at right angles, and are connected to the car wall frame profile or the light curtain bracket profile. The end face of the front column profile is plugged with an angle code, which is plugged into the hole of the front column profile through a support leg and is arranged to close the end face, and a mounting threaded hole is formed on the angle code. The front column profile is mainly used to connect the car wall structure and the light curtain structure, so two connection slots are formed, and the two connection slots have the same shape. The connected structures can be interchanged, and the door opening can be conveniently selected. The side connected to the light curtain bracket profile is used as the door opening side.

[0011] Furthermore, the rear column profile is formed into a structure with a right-angled cross section, with a connection notch formed toward the front end, a back plate connection groove formed at the rear, and a car rear wall connection groove provided on the inner plane of the right angle, and both the back plate connection groove and the car rear wall connection groove are "T"-shaped cross-sectional grooves, in which fixing screws are embedded, and the fixing screws are connected to the back plate and the car rear wall. The connection notch of the rear column profile is mainly used to connect the car wall, and the rear wall connection groove is used to fix the rear wall of the car. The rear wall of the car is relatively thicker, and components such as an operating box need to be installed on the rear wall, so the rear column profile has an independent structure for connecting the rear part.

[0012] Furthermore, the cross-sectional shape of the ceiling frame profile is formed with a fixed bottom edge, a top plate fixing groove, an angle code socket, and a lighting installation cavity. The fixed bottom edge serves as the basic bottom edge connected to the front column profile, the rear column profile, and the car wall frame profile. A wiring cavity is arranged at the upper part of the fixed bottom edge. The top plate fixing groove is arranged horizontally. A lighting installation cavity is arranged at the lower part of the top plate fixing groove. An angle code socket is arranged in the gap of the ceiling frame profile.
