Problems solved by technology

However, the existing speed limiter assembly installed on the car still needs the cooperation of the speed limit rope or an additional trigger device to realize the triggering of the safety gear, resulting in a high installation stroke and a relatively complicated structure
[0004] In addition, most speed limiters can only detect predetermined speed triggers, and they can only be triggered safely through steel wire ropes and supporting tensioning devices. The safety chain is complicated and the function is single.

Embodiment 1

[0056] Such as Figure 1-12 As shown, the car monitoring device of this embodiment includes a mounting base and a first roller 1, a second roller 2 installed on it, a monitoring trigger mechanism, a booster mechanism and a lifting mechanism, the first roller 1, the second roller 2 are respectively located on both sides of the guide rail 0 of the car. Initially, they are close to the guide rail with a certain positive pressure, and rotate by friction during the upward or downward process of the car, so as to realize the monitoring of the monitoring trigger mechanism; the monitoring trigger mechanism is used to pass the first Roller 1 monitors the running state of the car, and triggers the booster mechanism and the lifting mechanism when needed; the booster mechanism is used to increase the positive pressure between the first roller and the car guide rail after the monitoring trigger mechanism is triggered; the lifting mechanism is used to After the triggering of the monitoring ...

Embodiment 2

[0075] The car monitoring device of this embodiment is different from Embodiment 1 in that: only one-way triggering can be realized, the structure is simplified, and the requirements of different applications are met;

[0076] Specifically, only one pawl needs to be reserved for the ratchet member, correspondingly, only one pull rod is required, and only one brake wheel is required.

[0077]The car monitoring device of this embodiment is installed on the car of the vertical conveying equipment of this embodiment.

[0078] Other structures can refer to Embodiment 1.

Embodiment 3

[0080] The car monitoring device of the present embodiment differs from Embodiment 1 in that:

[0081] The brake wheel can be replaced by a brake wedge or other existing common structures, and it only needs to push away the push plate after contacting the car guide rail.

[0082] The car monitoring device of this embodiment is installed on the car of the vertical conveying equipment of this embodiment.

[0083] Other structures can refer to Embodiment 1.

Abstract

The invention relates to a car monitoring device and an elevator, wherein the car monitoring device includes a mounting seat, a first roller arranged on the mounting seat, a monitoring trigger mechanism, a booster mechanism and a lifting mechanism; The car guide rail fits; the monitoring trigger mechanism is used to monitor the running state of the car through the first roller, and trigger the booster mechanism and the lifting mechanism when needed; the booster mechanism is used to make the first roller and the car The positive pressure of the car guide rail is increased; the pulling mechanism is used to use the positive pressure of the first roller and the car guide rail to provide a pulling force to trigger the safety protection device after the monitoring trigger mechanism is triggered. The invention integrates the first roller, the monitoring and triggering mechanism, the boosting mechanism and the lifting mechanism into the mounting seat to realize the operation monitoring and diagnosis of the car, and the triggering and braking of the emergency protection device, with simple structure, integrated functions and miniaturization.

Description

technical field [0001] The invention belongs to the technical field of safety monitoring, and in particular relates to a car monitoring device and vertical conveying equipment. Background technique [0002] The traditional elevator car monitoring is to detect the moving speed of the car through the speed limiter to realize the detection of falling down and overspeed. It is one of the safety control components in the elevator safety protection system. When the elevator overspeeds during operation, or even falls, the overspeed governor and safety gear will act in conjunction to stop the car. [0003] Most of the existing speed governors are installed in the elevator machine room, and some are also installed on the car. For example, the patent document whose publication number is WO2011146050A1 discloses a speed governor assembly installed on the car. However, the existing speed limiter assembly installed on the car still needs the cooperation of the speed limit rope or an add...
