Problems solved by technology

The hydraulic drive is used to drive the elevator or lifting equipment. The hydraulic drive runs more smoothly than the traction drive when the building height is low. However, on the one hand, the elevator shaft needs a large space to accommodate the components of the hydraulic drive structure. more material and higher cost

Embodiment 1

[0032] The invention provides an elevator / lifting device, which can cooperate with a revolving staircase to realize the separation of the elevator passage and the stair passage in a stair passage. In different ways, the transmission structure can be simplified and the load on the elevator and / or lifting equipment can be optimized in a limited space, so that the elevator / lifting equipment can run safely and stably. It should be noted that existing buildings without elevators / lifting devices are usually rebuilt based on the pedestrian passage walls in the stairwell to install elevators, and there are the following problems:

[0033] 1. The existing traction and hydraulic transmissions have the problems of unstable operation, large renovation space and large functional requirements;

[0034] 2. The modification method of hanging the elevator along the pedestrian passage wall in the stairwell. The elevator car or the bearing mechanism is equivalent to a cantilever beam, which only t...

Embodiment 2

[0049] This embodiment is a further improvement and / or supplement to Embodiment 1, and repeated content will not be repeated here.

[0050] see figure 2 In Embodiment 1, the connecting body 30 is a simply supported beam structure with respect to the first supporting body 20. One side of the connecting body 30 abuts against the first supporting body 10 through the first groove body 11, and the other side passes through the first convex body 12. To abut against the first support body 10 , this embodiment describes the way of connection and / or abutment between the connecting body 30 and the first convex body 12 .

[0051] see image 3 and Figure 4 , the first support body 10 is provided with a first convex body 12 opposite to the first carrier body 100 . Preferably, the first carrier 100 passes through a side wall of one side of the first support 10 . The end of the first carrier 100 can be inserted into the first convex body 12 . One side of the first protrusion 12 is in ...

Embodiment 3

[0061] This embodiment is a further improvement and / or supplement to Embodiments 1 and 2 and their combination, and the repeated content will not be repeated.

[0062] In Embodiment 1 and Embodiment 2, there may be problems of slippage and wear in the abutment and / or connection between the connecting body 30 and the second groove body 21. This embodiment aims at the connection and / against the way to improve.

[0063] Preferably, the connecting body 30 can move along the first groove body 11 . The connecting body 30 can move along the second groove body 21 . Preferably, the second tank body 21 / the first tank body 11 and the connecting body 30 move relative to each other. The connecting body 30 can relatively slide / roll along the first groove body 11 and / or the second groove body 21 .

[0064] Preferably, the connecting body 30 can also be connected with the second tank body 21 . The connecting body 30 can also be connected with the first tank body 11 . In this implement...

Abstract

The invention relates to lifting equipment based on a different-direction non-equidistant double-barrel spiral driving structure. The lifting equipment based on the different-direction non-equidistant double-barrel spiral driving structure comprises a first bearing body and a second bearing body, and further comprises a first supporting body and a second supporting body which are arranged in a mutual sleeving mode and can rotate relatively, wherein the first supporting body is provided with a first groove body and a first convex body which are the same in spiral direction and screw pitch; the second supporting body is provided with a second groove body which is in the same-direction equidistant double-helix shape and is different from the first groove body in spiral direction; the first bearing body is connected with the first supporting body along the first convex body in a manner of spirally surrounding the first supporting body; and the second bearing body obtains the driving force which is provided by rotation of the second supporting body and moves along the first groove body in a manner that the second bearing body can penetrate through the first groove body and the second groove body so as to be connected with and / or abut against the first convex body. According to the lifting equipment based on the different-direction non-equidistant double-barrel spiral driving structure provided by the invention, each bearing body is arranged in a simply supported beam mode and can be stressed in a balanced mode without additional balance weight, so that operation is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of elevators or hoisting equipment, in particular to a hoisting equipment based on a different-direction non-equidistant double-cylinder helical drive structure. Background technique [0002] Lifting equipment or elevators are used to transport people or things to a number of specific floors or specific heights inside or outside a building. On the one hand, elevators or lifting equipment need to operate safely to transport people or objects to a specified height; on the other hand, for buildings such as residences, viewing platforms, and garages without elevators or lifting equipment, consideration can be given to building on the basis of existing buildings Adding elevators or lifting equipment to the building can provide convenience for people with disabilities. It needs to be remodeled in combination with the reserved space in the existing building. For safety and space saving, it is necessary to reduce th...
