Problems solved by technology
This distance prevents the maintenance personnel from approaching the maintenance object when needed, which brings a lot of inconvenience to the maintenance and presents the danger of the maintenance personnel falling
Moreover, it is easy for the tool to fall to the bottom of the well through the gap during maintenance, so that the maintenance personnel have to stop the operation and go down to the bottom of the well to pick up the tool

Embodiment Construction
[0019] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] figure 1 It is a schematic diagram schematically showing one embodiment of the elevator of the present invention. The elevator 100 includes a hoistway 102 , a car 110 , a counterweight 104 , and a traction machine 108 . The car 110 and the counterweight 104 are connected by a traction rope 106 , and are raised and lowered in the hoistway 102 under the traction of the traction machine 108 .
[0021] figure 2 is short for figure 1 A schematic diagram of the car wall structure of car 110 is shown. figure 2 This corresponds to a schematic view of the inside of the car viewed from the entrance of the car 110 . The car 110 is mainly composed of a rear car wall 112 , car walls 114 on both sides, a car wall 116 , a floor 118 , and a ceiling 119 . The car wall 114 and the car wall 116 are respectively compo...

The invention relates to an elevator car (110) in which the car wall (112) in at least one direction is longitudinally divided into two sections, upper and lower, and transversely divided into sections a (a≥2). A transverse rotation axis (302) is provided between the lower wall panels (112a-112c) and the car floor (118). Usually, a positioning pin (310) is provided at both ends of each lower wall panel in the width direction. The positioning pin is inserted longitudinally into the lower wall panel and the seat (304) of the transverse rotation axis to fix the lower wall panel. In portrait position. During maintenance, by removing the two positioning pins, the lower wall plate can be rotated to the lateral position around the transverse rotation axis toward the outside of the car, making it a maintenance workbench. For the lower wall panel adjacent to the workbench, disconnect it from the transverse rotation axis, and unplug the positioning pin away from the workbench among its two positioning pins, so that the lower wall panel can be positioned with the other positioning pin. The shaft rotates to the side of the workbench to become a railing.
Description
technical field [0001] The invention relates to an elevator and its car. Background technique [0002] Various devices and instruments are often arranged in the shaft of the elevator. Especially for machine-room-less elevators, important devices and instruments such as control cabinets, traction machines, and speed limiters are also installed in different positions in the hoistway, which require regular maintenance. In order to maintain the installation instrument in the well, sometimes maintenance personnel need to drive the elevator to a position close to the maintenance object, and then stand on the ceiling of the car for maintenance. However, depending on the structure of the elevator, it may not be possible to perform maintenance while standing on the car ceiling. [0003] Japanese Patent Laid-Open No. 10-231074 discloses an elevator. The elevator is provided with an opening for maintenance on the car wall corresponding to the direction of the maintenance object (for...
