Description

Technical Field

[0001] The utility model relates to the technical field of elevator electromechanical maintenance, in particular to a guide rail braking device used for elevator maintenance. Background Art

[0002] Electromechanical applications are extremely common in life. An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped cabin, used to carry people or goods in multi-story buildings. There are also step-type elevators, with treads mounted on tracks for continuous operation, commonly known as escalators or moving walkways. Vertical lifts require guide rail brake devices for elevator maintenance, that is, brake devices that control the movement of the guide rails. However, in actual use, guide rail brake devices of similar structure used for elevator maintenance still have many defects, such as: relying on an electric telescopic rod to make the brake plate closely contact with the guide rail of the elevator to complete the braking. The long-term contact between the brake plate and the guide rail will cause heat and failure, posing a certain safety risk. Utility Model Content

[0003] The purpose of the utility model is to provide a guide rail braking device for elevator maintenance to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide rail brake device for elevator maintenance, comprising a guide rail body and a brake body, both sides of the brake body are fixedly connected with connecting plates, one end of the connecting plate is fixedly connected with an electric hydraulic cylinder, one end of the piston rod of the electric hydraulic cylinder is fixedly connected with a connecting frame, one end of the connecting frame is provided with a brake plate, one end of the brake plate is provided with a plurality of evenly distributed heat dissipation ports, a cooling mechanism is provided in the brake plate, and an adjustment mechanism is provided on the inner wall of one end of the connecting frame.

[0005] By starting the rotating motor, the rotating shaft can be rotated, and the rotation of the rotating shaft can cause the rotating disk to rotate. The rotation of the rotating disk can cause the top rod to rotate. At this time, the rotating ball rotates in the inner wall of the rotating groove and rolls at one end of the inclined block. When the rotating ball moves to the highest end of the inclined block, starting the electric hydraulic cylinder can move the connecting frame. The movement of the connecting frame can cause the brake plate to move and contact the wall of the guide rail body to perform a braking operation. When braking, starting the rotating motor can cause the rotating ball to separate from the highest point of the inclined block. At this time, the brake plate can retract under the tension of the movable spring. Reversing the direction of the rotating motor can make the brake plate intermittently contact the wall of the guide rail body, thereby avoiding thermal failure. In addition, the heat dissipation port and the coolant pipe can quickly cool down the brake plate, thereby avoiding thermal failure.

[0006] Preferably, the cooling mechanism includes a coolant pipe, and one side of the brake plate is provided with a plurality of connection ports that are evenly distributed and extend into the heat dissipation port. The inner wall of the connection port is fixedly connected to the coolant pipe. The provision of the coolant pipe can quickly cool down the heat passing through the heat dissipation port, so that the brake plate can be cooled quickly.

[0007] Preferably, movable grooves are provided on both sides of one end of the connecting frame, a movable spring is fixedly connected to the inner wall of one end of the movable groove, a movable rod is fixedly connected to one end of the movable spring, the movable rod and the brake plate are fixedly connected, and the movable rod is arranged to slide in the inner wall of the movable groove, and the position of the brake plate can be adjusted to avoid thermal failure of the brake plate.

[0008] Preferably, the adjustment mechanism includes an inclined block fixedly connected to one end of the brake plate, and a push rod is provided on the inner wall of one side of the connecting frame. The push rod is close to the inclined surface of the inclined block, and the setting of the push rod can cooperate with the inclined block to facilitate the brake plate to contact the wall surface of the guide rail body again.

[0009] Preferably, a rotating groove is provided at one end of the push rod, and a rotating ball is rotatably connected to the inner wall of the rotating groove. A rolling fit is formed between the rotating ball and the inclined surface of the inclined block. The rotating ball can rotate in the inner wall of the rotating groove, thereby avoiding friction damage between the push rod and the inclined block.

[0010] Preferably, a rotating motor is fixedly connected to the inner wall of one end of the connecting frame, the output shaft of the rotating motor is fixedly connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a rotating disk, one side of one end of the rotating disk is fixedly connected to the top rod, the rotating disk is arranged so that it can be rotated under the rotation of the rotating shaft, and the rotating shaft can be rotated under the rotation of the output shaft of the rotating motor.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The rotating shaft can be rotated by starting the rotating motor, and the rotation of the rotating shaft can rotate the rotating disk, and the rotation of the rotating disk can rotate the top rod. At this time, the rotating ball rotates in the inner wall of the rotating groove and rolls at one end of the inclined block. When the rotating ball moves to the highest end of the inclined block, the electric hydraulic cylinder can be started to move the connecting frame. The movement of the connecting frame can move the brake plate and contact the wall surface of the guide rail body to perform a braking operation. When braking, starting the rotating motor can make the rotating ball leave the highest point of the inclined block. At this time, the brake plate can retract under the pulling force of the movable spring. Reversing the direction of the rotating motor can make the brake plate intermittently contact with the wall surface of the guide rail body, thereby avoiding thermal failure. In addition, the heat dissipation port and the coolant pipe can quickly cool down the brake plate, thereby avoiding thermal failure.

[0013] 2. The push rod can cooperate with the inclined block so that the brake plate can contact the wall of the guide rail body again; the rotating ball can rotate in the inner wall of the rotating groove to avoid friction damage between the push rod and the inclined block; the rotating disk can be rotated under the rotation of the rotating shaft, and the rotating shaft can be rotated under the rotation of the output shaft of the rotating motor.
