Problems solved by technology
The block brakes of the car are located on both sides of the car. The brake principle is to clamp the elevator rails. The block brakes and the rails will wear out at the same time. The process of replacing the rails is complicated and the cost is high.
The disadvantage is that once the electrical control fails or the main hoisting cable breaks and the car falls freely, the electrical control cannot make the brake work, and the block brake of the car is not enough to stop the elevator car. Without any compensation method, The car can only fall freely, which happens from time to time
The loss of the steel cable, the car, and the weight is very large, which seriously damages the service life of the elevator

Embodiment 1
[0027] Such as figure 1 As shown, the hoisting cable 2 is connected to the traction motor in the machine room 1 and extends from the machine room 1, and is connected to the car 8. The traction motor drives the traction sheave to rotate after the speed of the reducer, and the traction rope is connected to the traction motor. The traction generated by wheel friction realizes the lifting movement of the car and the counterweight to achieve the purpose of transportation. The car guide shoes 7 fixed on the car 8 can reciprocate and move up and down along the car guide rail 3 installed on the wall of the building hoistway to prevent the car from skewing or swinging during operation.
[0028] A vertical steel beam is welded in parallel to the left side of the original frame of the car. The bottom is 25cm lower than the bottom of the original frame, and the top is about 25cm lower than the top of the original frame. The upper end of the vertical steel beam is horizontally welded to a hori...

The invention provides a standby braking system for an elevator. The standby baking system comprises a safe standby steel cable, guide wheels and a brake, wherein four corners on an elevator lift car are provided with the four guide wheels, the upper end of the safe standby steel cable is fixedly arranged on the top of a hoistway and sequentially passes through the four guide wheels, then, the lower end of the safe standby steel cable is connected with an extension spring arranged at the bottom of the hoistway, the center of the bottom of the lift car is provided with the brake, the brake comprises a hydraulic spanner and gear rope grippers, the hydraulic spanner passes through the gear rope grippers and drives the gear rope grippers to rotate, the safe standby steel cable passes through notches of the gear rope grippers, and the gear rope grippers at the upper and lower rows rotate in different directions, so that the safe standby steel cable is seized. The standby baking system has the advantages that the standby compensation braking system can be automatically or manually opened at the moment, so that the lift car can stop without doing vertical moving for waiting rescue. Moreover, the safe steel cable and the brake are replaced after the standby baking system operates for a period of time, the cost is low, and the work procedure is simple.
Description
Technical field [0001] The invention relates to an elevator component, in particular to an elevator braking system. Background technique [0002] In the past 20 years, China's real estate has developed rapidly. The elevator has become a necessity of life. But with the passage of time, a large part of the elevators have become old. The elevator can be said to be a kind of high-risk equipment. Once an accident occurs, the people in the elevator will completely lose the ability to save themselves. In elevators with a certain service life, performance and functions continue to decline, problems often occur, accidents occur frequently, and very large personnel and property losses are caused. [0003] The elevator brake system in the prior art is composed of two parts. The brake is on the top of the elevator slot, and the rear of the motor is drawn. The electric system controls the brake of the steel cable to reach the parking car. The car block brakes are located on both sides of th...
