Safety protecting device for foundation pit-free elevator

Abstract

The invention discloses a safety protecting device for a foundation pit-free elevator. The safety protecting device comprises an underbed, a cleaning mechanism and a reinforcing mechanism, wherein a fixed rack is arranged on the surface of the top end of the underbed, a telescopic cylinder is arranged on the side, located on the fixed rack, of the surface of the top end of the underbed, a main post is arranged on the surface of the top end of the telescopic cylinder, the main post penetrates the surface of one side of the telescopic cylinder and one side of the main post is located in the telescopic cylinder, the cleaning mechanism is located at the connection of the telescopic cylinder and the main post and comprises a turnplate, the turnplate penetrates the surface of one side of a guiding telescopic cylinder, and one side of the turnplate is located outside the guiding telescopic cylinder. The service lives of the telescopic cylinder and the main post are prolonged by means of the turnplate, so that it is ensured that a second fixing plate generates an upward push force to play a role of alleviating the speed of the elevator. It is convenient to reinforce connection between a fixed block and a mounting seat by means of a seal ring, so that it is ensured that a buffering weight applies an upward counter-acting force to the falling elevator.

Description

technical field [0001] The invention belongs to the technical field of safety protection devices, in particular to a safety protection device for elevators without foundation pits. Background technique [0002] Along with the explosive growth of elevators, the number of elevator accidents remains high. Elevator safety has become a new hidden danger for urban public safety. Due to the frequent occurrence of elevator accidents, some people even talk about "elevators". It is necessary to frequently and irregularly maintain and repair the elevator to ensure safety. [0003] However, there are still some disadvantages in the existing safety protection devices for elevators without foundation pits. After the device is used for a long time, dust will fall on the gap between the main rod and the telescopic tube, which will easily block the movement of the main rod inside the telescopic tube. It is inconvenient to clean it. In addition, when the device runs for a long time, the devi...

[0003] However, there are still some disadvantages in the existing safety protection devices for elevators without foundation pits. After the device is used for a long time, dust will fall on the gap between the main rod and the telescopic tube, which will easily block the movement of the main rod inside the telescopic tube. It is inconvenient to clean it. In addition, when the device runs for a long time, the device will be eroded by external factors, which will make the connection between the steel wire rope and the buffer weight loose, which will easily cause the buffer weight to fall off. For this reason, we propose a Safety protection device for elevator without foundation pit
