Flat-layer locking device for elevator

Abstract

The invention relates to a flat-layer locking device for an elevator. The device comprises a locking motor (1), a rotating mechanism (2), clamping groove boards (4), guide bearings (5), connecting rods (6) and proximity switches (7). The locking motor (1) is fixed on a frame of an elevator trolley. The center of the rotating mechanism (2) is connected with the locking motor (1). The two sides of the rotating mechanism (2) are each connected with the corresponding guide bearing (5) through one connecting rod (6). Each clamping groove board (4) is fixed on a stand column. Each clamping groove board (4) is provided with a clamping groove. Each proximity switch (7) is arranged on the corresponding connecting rod (6) and is in signal connection with the locking motor (1). When the elevator moves vertically to arrive at a preset position, the proximity switches (7) output signals, the locking motor (1) operates, and the rotating mechanism (2) pulls the connecting rods (6) so as to push the guide bearings (5) to be locked into the clamping grooves; on the contrary, the guide bearings (5) are released. Compared with the prior art, the device has the advantages of being simple in structure, high in reliability and good in balance.

Description

technical field [0001] The invention relates to an elevator, in particular to an elevator leveling locking device. Background technique [0002] The development of elevators is at a peak state. In order to improve the utilization rate of the site, most manufacturers or individuals choose more multi-storey buildings. Therefore, a device is also needed to facilitate the lifting and lowering of goods. Due to the high cost and low carrying capacity of ordinary elevators, it is not suitable for loading goods of tens of tons or hundreds of tons, so hydraulic lifts with high carrying capacity have been developed to assist production and cargo transportation. The elevator is safe and has a large load capacity, and it is easy to maintain, which makes this special industry develop faster. [0003] The safety switches of the elevator are designed according to safety needs, including fence door limit, cage door limit, top door limit, limit switch, upper and lower limit switches, counte...

Problems solved by technology

However, this mechanism has many hinged structures and bending parts, is sensitive to machining errors, has high manufacturing costs, and the mechanism is easily deformed after long-term operation, so that the locking roller cannot be accurately aligned with the locking bayonet, and the locking function becomes invalid.
