DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1 and Figure 2 As shown, the double-car structure provided by the embodiment of the present invention includes: an upper car 100, a lower car 200, an intermediate platform 300 and a spacing adjustment device 400; the intermediate platform 300 is located between the upper car 100 and the lower car 200; the upper car 100 and the lower car 200 are respectively connected to the intermediate platform 300 through the spacing adjustment device 400.

[0026] The spacing adjustment device 400 may use a lead screw, a telescopic hydraulic cylinder, a transmission chain or a steel wire rope as a transmission member to drive the upper car 100 and the lower car 200 to move up and down relative to the intermediate platform 300, thereby adjusting the spacing between the upper car 100 and the lower car 200. The double-car structure does not need to be provided with a frame structure outside, and does not need to rely on the frame structure for layout and assembly. The overall structure size is smaller, the structure is more compact, and the space occupied is smaller.

[0027] In a preferred embodiment, the distance adjustment device 400 can use a lead screw as a transmission member, and the upper car 100 and the lower car 200 are respectively matched with the lead screws, and the lead screws are matched with the upper car 100 and the lower car 200 in opposite directions. When the reduction motor drives the lead screw to rotate, one of the upper car 100 and the lower car 200 rises and the other falls, thereby achieving distance adjustment.

[0028] In the embodiment of the present invention, the middle platform 300 is connected with a side guide rail 500 extending from bottom to top; the upper car 100 and the lower car 200 are both equipped with a first roller 101 and a second roller 102, and the side guide rail 500 is pressed between the first roller 101 and the second roller 102 so that the first roller 101 and the second roller 102 roll along the side guide rail 500. On the one hand, it can ensure that the upper car 100 and the lower car 200 can be smoothly lifted and lowered along the extension direction of the side guide rail 500. On the other hand, the side guide rail 500 serves as a guide and limit device to prevent the upper car 100 and the lower car 200 from being deflected, thereby improving the stability of the upper car 100 and the lower car 200.

[0029] Furthermore, side guide rails 500 are respectively connected to both sides of the middle platform 300 , and the upper car 100 and the lower car 200 are slidably fitted between the two side guide rails 500 , thereby improving the stability of the upper car 100 and the lower car 200 .

[0030] In an optional embodiment, the spacing adjustment device 400 includes: a first adjustment member 410 and a second adjustment member 420; the upper car 100 and the lower car 200 are both located between the first adjustment member 410 and the second adjustment member 420; the first adjustment member 410 and the second adjustment member 420 are installed on the middle platform 300, and the first adjustment member 410 and the second adjustment member 420 are both connected to the upper car 100 and the lower car 200.

[0031] When the upper car 100 and the lower car 200 are large in size, the first adjusting member 410 and the second adjusting member 420 are used to jointly drive the upper car 100 and the lower car 200, thereby realizing synchronous lifting and lowering drive on both sides of the car, which can ensure that the car can be lifted and lowered steadily and smoothly.

[0032] In an optional embodiment, a pulley 600 is installed at the bottom of the middle platform 300, and the main wire rope 700 can extend around the pulley 600. On the one hand, the force of the wire rope can be transmitted to the middle platform 300, and on the other hand, the movement resistance of the main wire rope 700 is reduced.

[0033] Furthermore, the middle platform 300 is installed with at least two pulleys 600 , at least one pulley 600 is located on one side of the middle platform 300 , and at least one pulley 600 is located on the other side of the middle platform 300 .

[0034] The double-car structure is connected with a traction system, and the main steel wire rope 700 of the traction system is passed under the pulley 600 and extends upward to generate an upward lift, which can pull the double-car structure to achieve lifting movement.

[0035] like Figure 1 As shown, the upper car 100 includes: an upper car body 110 and an upper base 120, the upper car body 110 is connected to the upper part of the upper base 120, and the upper base 120 is connected to the middle platform 300 through a spacing adjustment device 400. The spacing adjustment device 400 drives the upper base 120 to rise and fall relative to the middle platform 300, thereby adjusting the overall lifting movement of the upper car 100, so that the upper car body 110 can have a larger lifting stroke.

[0036] Furthermore, the lower car 200 includes: a lower car body 210 and a lower base 220, the lower car body 210 is connected to the lower side of the lower base 220, and the lower base 220 is connected to the intermediate platform 300 via a spacing adjustment device 400. The spacing adjustment device 400 drives the lower base 220 to rise and fall relative to the intermediate platform 300, thereby adjusting the overall lifting movement of the lower car 200, so that the lower car body 210 can have a larger lifting stroke.

[0037] In the case of comprehensive use of the upper car 100 and the lower car 200, the adjustment range of the distance between the upper car body 110 and the lower car body 210 is larger, and it can be more widely applied to buildings with different floor heights.

[0038] The elevator provided in the embodiment of the present invention is equipped with the double-car structure described in the above-mentioned embodiment. The elevator has the technical effects of the above-mentioned double-car structure, which will not be repeated here.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
