Problems solved by technology

[0002] The leveling control of the existing elevator is realized by the method of sensor detection and electrical control friction braking, and the leveling accuracy will change due to the performance drift of the detection control components and the friction coefficient of the friction parts; According to the characteristics of the rack-and-pinion elevator itself, it is necessary to find a leveling control method with more stable leveling accuracy; the safety braking measures of the existing rack-and-pinion elevators are either by braking the motor shaft or by braking the gear shaft. These methods belong to the friction braking method, and there may be potential safety hazards caused by friction material wear or oil pollution; in addition, if there is a problem with the drive gear, the aforementioned methods will be helpless; and the drive gear Problems are possible, therefore, in order to ensure safety, the rack and pinion elevator must be equipped with a reliable safety braking device that can deal with problems including driving gears and similar safety problems

Embodiment 1

[0023] Example 1, Figure 9 It is a schematic diagram of Embodiment 1, and the drawing shows the appearance of the side of the elevator. The leveling control and safety braking device is installed on the rack-and-pinion elevator and is temporarily in a free position, and the elevator is ready to run or is running. Figure 10 It is a schematic diagram of the situation in which the safety braking device of embodiment 1 brakes the elevator, (the left and right described in the previous figure are viewed from the inside of the elevator to the side of the elevator, Figure 9 , Figure 10 It is viewed from the outside to the side of the elevator, so the left and right directions are just opposite), the leveling control and safety braking device must be installed under the load-bearing structure of the elevator, directly contacting or contacting the load-bearing through the intermediate transition parts, the leveling layer used For the description of the composition and function of ...

Embodiment 2

[0024] Embodiment 2 is an elevator that installs the independent leveling control and safety braking device assembly of the rack-and-pinion elevator, Figure 11 It is a schematic diagram of embodiment 2, which shows the situation when the solenoid valve is in the reset position, the leveling control and the safety braking device perform braking, Figure 12 It is a schematic diagram of when the solenoid valve is in the working position and the leveling control and safety brake device is in the free position in Embodiment 2. The load-bearing frame of the independent leveling control and safety brake device assembly is connected by bolts or other The connection method is connected with the load-bearing structure of the elevator car, and the solenoid valve control circuit and input pipeline interface are connected with the electrical control circuit interface and pipeline interface of the elevator, see Figure 8 As shown, and described in paragraph [0008]; its internal structure i...

Abstract

The invention provides a flat-layer control and safety braking device of a gear and rack type elevator. A movable rack can move on a rail assembly horizontally or remains at certain determined positions, the top of the movable rack makes direct contact with a main bearing structure of an elevator lift car after entering the brake state or makes contact with a bearing structure through an intermediate transition bearing component, and a control mechanism of the movable rack controls the movable rack to move horizontally on a rail hole or stops or remains at certain determined positions; and the determined positions comprise a brake position engaged to an elevator drive rack or a free position which is completely separated from the elevator drive rack and is a certain interval away from the elevator drive rack. Flat-layer control and safety protection braking are performed in a rack engaged manner, and the beneficial effects that flat-layer accuracy and maintenance precision are remarkably improved, and safety protection braking quality is improved are achieved.

Description

technical field [0001] The invention relates to the field of leveling control and safety braking devices of elevators, in particular to a leveling control and safety braking device of a rack-and-pinion type elevator.
