Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a double-guide straight-moving elevator with adjustable hoistway height. Background Art

[0002] The elevator hoistway is the space in which the car and counterweight device or (and) the hydraulic cylinder plunger move. This space is bounded by the bottom of the hoistway pit, the hoistway walls and the hoistway top.

[0003] The hoistway is the space for the elevator to run. It consists of the hoistway wall, the bottom plate and the top plate. It adopts reinforced concrete ring beam or all reinforced concrete structure. Its strength should meet the specifications of the elevator load and rated speed. The distance between its inner wall and the outer wall of the car should meet the relevant national standards. The elevator counterweight and the car are set inside it. It should be properly ventilated, and various openings, top spaces and pits for maintenance and other purposes should be set. The structure and materials of its bottom and top plates should comply with relevant regulations, and its holes and embedded iron parts should be reserved according to the distribution of the guide rail frame, the specifications of the buttons and indicator lights, and its barriers should be rigid. Its height design should take into account the total travel height of the elevator, the top floor height, and the pit depth.

[0004] In order to prevent the possible harm caused by the elevator hitting the top, when the elevator reaches the highest floor, there should be a space between the top of the ladder and the top plate of the shaft.

DETAILED DESCRIPTION

[0027] Through the sliding mechanism 5, the car 4 has high stability when moving up and down, and can remain stable without shaking, thereby improving practicality. Through the adjusting mechanism 7, the elevator shaft can be adjusted in height to meet the needs of passengers in emergency situations, thereby improving the adaptability of the elevator.

[0028] like Figure 2 As shown, the sliding mechanism 5 includes a slide rail 1 51, the bottom of which is fixedly connected to the inner wall of the movable shaft 2, the interior of the slide rail 1 51 is slidably connected to a slider 1 52, the left and right inner walls of the fixed shaft 3 are symmetrically fixedly installed with slide rails 2 53, the interior of the slide rails 2 53 is slidably connected to a slider 2 54, the rear inner wall of the fixed shaft 3 is symmetrically fixedly installed with slide rails 3 55, and the interior of the slide rails 3 55 is slidably connected to a slider 3 56.

[0030] like Figure 3 As shown, the moving component 6 includes a bracket 61, the lower end of the bracket 61 is fixedly connected to the top of the moving shaft 2, the inner side of the bracket 61 is rotatably connected to a winding drum 62, the right end of the winding drum 62 is transmission-connected to a first motor 63, the lower end of the first motor 63 is fixedly connected to a mounting seat 64, a steel wire rope 65 is wound around the surface of the winding drum 62, and the lower end of the steel wire rope 65 is fixedly connected to a hanging seat 66.
