technical field

The utility model relates to an installation protection device, in particular to a braking stop device for a vertical shaft hanging basket.

Background technique

In the shaft construction of hydropower projects, hanging baskets are often used as a means of upper and lower transportation. After the hanging basket is lifted from the bottom of the well to the wellhead, it is generally stopped by manual control of the winch. Since the operator cannot accurately control the docking position of the hanging basket, it is inconvenient for the construction personnel to enter and exit the hanging basket; if the operation is improper or not timely, the hanging basket will impact the top The safety risk of the gantry, resulting in safety accidents.

Contents of the invention

The technical problem to be solved by the utility model is to provide a brake stop device for the vertical shaft hanging basket, which can solve the problems of inaccurate parking positioning of the vertical shaft hanging basket under manual control and untimely operation, which is prone to rushing to the top, and has a simple structure and high safety performance .

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a braking stop device for a hanging basket in a shaft, including a hanging basket, the hanging basket is suspended under the door frame through the steel wire rope of the hoist, and the steel wire rope of the hoist passes through the shaft installed on the top of the shaft The fixed pulley on the mast is connected with the hanging basket behind,

The lower part of the top beam of the gantry is equipped with a horizontal rod, a controller is hung on the horizontal rod, and a counterweight is hung under the controller;

The controller includes a transmission shaft, the eccentric hammer is connected to one end of the transmission shaft in rotation, the conductive rod is connected to the other end of the transmission shaft in rotation, and a conductive block is closely attached to the top of the conductive rod;

The controller cooperates with the circuit control system of the hoist.

The controller is fixed on the positioning plate.

The counterweight is suspended below the controller through a steel wire rope, and the steel wire rope is connected with the eccentric hammer.

The conductive rod and the conductive block of the controller are respectively provided with circuit cables connected in series with the circuit control system of the hoist to form a loop.

The utility model provides the brake stop device for the hanging basket of the shaft. When the hanging basket is raised to a predetermined position to lift the counterweight, the controller will disconnect the circuit circuit connected with the control system of the winch, so that the hanging basket will stop rising, thereby preventing The hanging basket rushes to the top. It ensures the construction safety, realizes precise braking and docking, and can solve the problems of inaccurate docking positioning and untimely operation of the manually controlled shaft hanging basket, which is prone to rushing to the top, and has a simple structure and high safety performance.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a brake stop device for a hanging basket in a shaft includes a hanging basket 8, the hanging basket 8 is suspended under the door frame 1 through a hoist wire rope, and the hoist wire rope passes through and is installed in the shaft 9 The fixed pulley on the mast 1 on the top is connected with the hanging basket 8, and the hoist 11 pulls the hanging basket 8 to lift up and down in the shaft 9;

The lower part of the top beam of the mast 1 is installed with a transverse bar 2, a controller 3 is hung on the transverse bar 2, and a counterweight 6 is hung below the controller 3;

The controller 3 includes a transmission shaft 3-1, the eccentric hammer 3-2 is rotationally connected with one end of the transmission shaft 3-1, the conductive rod 3-3 is rotationally connected with the other end of the transmission shaft 3-1, and the upper part of the conductive rod 3-3 is tightly fitted There are conductive blocks 3-4;

The controller 3 cooperates with the circuit control system 10 of the winch 9 .

The controller 3 is fixed on the positioning board 4 .

The counterweight 6 is suspended below the controller 3 through the wire rope 5, and the wire rope 5 is connected with the eccentric hammer 3-2.

The conductive rod 3-3 and the conductive block 3-4 of the controller 3 are respectively provided with a circuit cable 7 connected in series with the circuit control system 10 of the winch 11 to form a loop.

The working process of the present utility model is as follows:

When the hanging basket 8 needs to be lifted to the wellhead of the shaft 9, the hoist 11 pulls the hanging basket 8 to rise slowly, and rises to the predetermined position when the top of the hanging basket 8 lifts the counterweight 6. In the tilting state, the eccentric hammer 3-2 drives the transmission shaft 3-1 to rotate, prompting the conductive rod 3-3 to tilt down and separate from the conductive block 3-4, so that the circuit formed in series with the hoist 11 circuit control system 10 is disconnected, and the hoist 11 Stop working, and hanging basket 8 stops rising.

When the hanging basket rises to a predetermined position to lift the counterweight, the controller disconnects the circuit connected to the winch control system, prompting the hanging basket to stop rising, thereby preventing the hanging basket from rushing to the top. It ensures the construction safety, realizes precise braking and docking, and can solve the problems of inaccurate docking positioning and untimely operation of the manually controlled shaft hanging basket, which is prone to rushing to the top, and has a simple structure and high safety performance.
