Pressure adjusting mechanism for rope pressing mechanism of elevator

Abstract

The invention relates to a pressure adjusting mechanism for a rope pressing mechanism of an elevator. The pressure adjusting mechanism comprises the rope pressing mechanism matched with a rope walking wheel; the rope pressing mechanism comprises two rope pressing wheels connected with lever arms through connecting plates; the lever arms are connected with a pressure adjusting mechanism; the pressure adjusting mechanism comprises an adjusting device and a spring mechanism; the spring mechanism comprises a spring, a spring retainer and a spring bearer plate; the spring retainer is connected with the lever arms; the adjusting device passes through the spring retainer and the spring and then is in threaded connection with the spring bearer plate. When the pressure adjusting mechanism is assembled, the spring is unstressed, and after a housing case of the elevator is assembled, the adjusting device is rotated easily by a wrench outside the housing case, without any barrier, and the pressure of the rope pressing mechanism can be randomly adjusted as required; when the pressing adjusting mechanism is disassembled for maintenance, the adjusting device is unscrewed, so that the housing case of the elevator can be opened conveniently.

Description

technical field [0001] The invention belongs to the technical field of building hanging basket hoists, and in particular relates to a pressure regulating device of a hoist rope pressing mechanism. Background technique [0002] The common construction hanging basket is generally equipped with two hoists, and there is a pair of pressure pulleys on the upper part of the rope wheel inside the hoist. The traditional pressure rope mechanism has two structural forms: the first one requires a wrench to go deep into the inside of the casing to adjust the pressure of the pressure rope. Due to the small space inside the casing, it is very difficult to adjust, and it can only rotate 1 / 6 at a time. Weeks, time-consuming and labor-intensive. The second is the prestressed type. The spring is preloaded and fixed before assembly. It is not adjusted during use, but the pressure will become smaller after long-term use, causing the friction between the wire rope and the rope wheel to decrease ...

The traditional pressure rope mechanism has two structural forms: the first one requires a wrench to go deep into the inside of the casing to adjust the pressure of the pressure rope. Due to the small space inside the casing, it is very difficult to adjust, and it can only rotate 1 / 6 at a time. week, time consuming

The second is the prestressed type. The spring is preloaded before assembly and then fixed. It is not adjusted during use, but the pressure will become smaller after long-term use, causing the friction between the wire rope and the rope wheel to decrease and slip. The preload also makes it very difficult to assemble and disassemble the whole machine
