Problems solved by technology

[0003] 1. Poor safety and reliability
The single-brake power unit has only one set of electromagnetic brakes. When the brake fails, the entire power unit cannot work normally. The entire power unit is driven by the transmission mechanism, making the transmission mechanism unable to work.
[0004] 2. Poor running comfort
The start-stop impact of the construction elevator is the most direct cause of the wear and tear of the transmission parts of the construction elevator, aggravated failure, and frequent failures, and has a greater impact on the comfort of the occupants.
The construction elevator transmission mechanism has insufficient safety performance and no fault protection and control defects

Abstract

The invention discloses a dual-braking transmission mechanism of a construction hoist. The dual-braking transmission mechanism comprises a motor and a reducer, the motor is connected with the reducer, the two sides of the motor and the reducer are each provided with a DC electromagnetic brake which is mounted on a drive mounting plate with one or more sets of dual-braking power units as core parts, the drive mounting plate is provided with a safety protection and back gears and is mounted on a drive frame, side guiding wheels are mounted on the drive frame which is connected with connecting rods, the two ends of each connecting rod are provided with dual-guiding-wheel components, and each set of guiding wheels are matched with a main chord member of a hoist standard knot in matched mode and can roll on the main chord member in a guiding mode; a gear on an output shaft of the reducer is meshed with a rack on the standard knot, and the motor is electrically controlled to rotate forwards and reversely to achieve ascending and descending of the transmission mechanism. The dual-braking transmission mechanism is safe, reliable, stable and comfortable in operation, braking faults can be detected, and the transmission mechanism can be online in an electronic control mode to prevent the faults from being expanded or worsened; the transmission mechanism is wide in application range and especially suitable for the occasions with high safety risks.

Description

technical field [0001] The invention relates to a transmission mechanism of a construction elevator, in particular to a novel transmission mechanism of a construction elevator and a material hoist. Background technique [0002] At present, the construction elevator transmission mechanism generally adopts the single brake power unit mode. This single braking power unit method is relatively simple and convenient in structure, but there are many disadvantages: [0003] 1. Poor security and reliability. The single-brake power unit has only one set of electromagnetic brakes. When the brake fails, the entire power unit cannot work normally. The entire power unit is driven by the transmission mechanism, making the transmission mechanism unable to work. [0004] 2. Poor running comfort. During operation, due to the existence of start acceleration and stop deceleration, frequent start and stop shocks occur in varying degrees with the different operating speeds and workloads of the...
