An operation method for rapid pouring and hoisting equipment, including the following three working conditions:

1. Belt Conveyor Feeding Conditions

Step 1. The mast hook 101 of the mast crane 1 is connected to the main lifting point 2. When it is necessary to adjust the pouring height according to the position of the pouring warehouse surface, the pin-through cylinder 23 is activated, the pin rod 24 is retracted, and the telescopic belt conveyor 5 is released. limit, start the motor 9, the gear 8 meshes with the climbing rack 4, cooperate with the mast crane 1, the fabric belt conveyor device Ⅰ moves up and down, after moving in place, the pin threading cylinder 23 starts, and the pin rod 24 extends out and penetrates into the pin hole 301, Perform a position lock.

First, the jib frame of the mast crane 1 is luffed and vertically aligned with the main lifting point 2, and the mast hook 101 of the mast crane 1 is connected with the main lifting point 2 through a wire rope.

When it is necessary to adjust the pouring height according to the position of the pouring warehouse, the hydraulic station controls the pin-through cylinder 23 to start, the pin rod 24 retracts, the restriction on the telescopic belt conveyor 5 is released, and the motor 9, the gear 8 and the climbing rack 4 are started. Mesh, cooperate with mast crane 1, cloth belt conveyor device Ⅰ moves up and down, after moving in place, pin threading oil cylinder 23 starts, pin rod 24 stretches out and penetrates pin hole 301, carries out up and down position locking.

While the cloth belt conveyor device I moves up and down, the feeding telescopic belt conveyor 17 rotates along the corner bracket 19, and the discharge end of the feeding telescopic belt conveyor 17 can rotate along the support frame 18, so that the outlet of the feeding telescopic belt conveyor 17 The material end is positioned above the hopper 16 all the time, and the length of the feeding telescopic belt conveyor 17 changes to adapt to the angle change brought by moving up and down.

Step 2. According to the position of the warehouse surface, the telescopic belt conveyor 5 stretches and retracts, and at the same time adjusts the angle of the boom of the mast crane 1 to ensure that the hoisting rope of the mast crane is in a vertical stretch state relative to the fabric belt conveyor device Ⅰ, so as to avoid crooked pulling and slanting. II drives the swinging cloth belt conveyor 6 to swing along the axis of the second hopper 15, so that the lower hopper 41 is aligned with the material lowering point.

Through the telescopic belt conveyor 5, the swing angle of the distribution belt conveyor 6 is stretched and swayed, and at the same time, the distribution belt conveyor device I as a whole passes through the vertical translation of the climbing rack 4, the luffing of the mast crane 1, and the up and down movement of the mast hook 101 of the mast crane 1. Height adjustment can realize fast full-dimension pouring point full coverage pouring without dead angle.

During the pouring process, the inner and outer fabric belts of the telescopic belt conveyor 5 will inevitably deviate from the original axis position, which will cause deflection moment to the truss of the fabric fabric conveyor device I. In order to overcome such effects, on the one hand, the The truss of the telescopic belt conveyor 5 is designed to be strengthened laterally to ensure that it can bear the deflection moment; The angle adjustment of the belt conveyor 6 reduces the deflection moment.

Step 3: After the concrete is produced by the mixing building 29, it flows from the chute 30 into the feeding inlet of the telescopic belt conveyor 17, and then is transferred to the distributing belt conveyor device I, and then sent to the pouring site.

After the distributing belt conveyor device Ⅰ is adjusted in place, the concrete is produced by the mixing building 29 and flows from the chute 30 into the feeding inlet of the telescopic belt conveyor 17, and then transferred to the distributing belt conveyor device Ⅰ, and then sent to the pouring site to start pouring.

If it is necessary to adjust the pouring blanking point during the pouring process, step 1 and step 2 should be repeated in time to adjust the blanking point.

2. Hoisting conditions of the main hook of the mast crane

After the pouring of the above steps is completed, when hoisting is required, the telescopic belt conveyor 5 retracts, and the suspension locking point 25 is locked with the pin hole 301 of a suitable height through the locking pull cord 26, and the rotary mechanism II drives the swinging fabric belt conveyor 6 Rotate to make the locking plate 27 rotate to the position of the locking ear plate 28. After locking by the locking pin 43, the fabric belt conveyor device I is completely locked, and the mast crane 1 can be unhooked, and the mast crane 1 can be used to lift heavy objects Work.

Although the mast crane can only move back and forth along the front and back directions on the axis of the cloth belt conveyor device I, when the cloth belt conveyor device I is not working, the telescopic belt conveyor 5 retracts, and the swinging cloth belt conveyor 6 rotates and locks, and the entire cloth belt conveyor The actual stretching length of machine device Ⅰ is greatly shortened, and the swinging cloth belt conveyor 6 can also swing out the axis range of the mast hanging point. The retracted fabric belt conveyor device Ⅰ influences the hook to drop the hanging objects.

3. Belt conveyor hook hoisting conditions

When it is necessary to hoist the warehouse surface, control the solenoid valve to disconnect the solenoid valve seat plate 37 and the solenoid valve tongue 38 of a certain hook mechanism V, start the belt lifting hoist 31, and make the movable pulley 35 and the suspension hook 34 downward Move, after the suspension hook 34 is hoisted, the belt lifting hoist 31 drives the moving pulley 35 and the suspension hook 34 to move upwards, and the start motor drives the dolly 40 to move along the suspension hook track 39 to move the lifting item to the target position.

The purpose of setting up multiple hook mechanisms V is to meet the needs of different hoisting parts. The hook mechanism V close to the mast crane can hoist heavier loads because the boom is relatively short. On the mast crane foundation 42 platform, a suspension hook retrieving platform or a suspension hook can be extended to take materials from the warehouse surface, and after taking materials, carry out hoisting of articles to other warehouse surfaces.

The equipment has a variety of operation modes to choose from. On the one hand, it can be controlled and operated locally through the cab arranged near the platform of the mast crane foundation 42. On the other hand, it can be operated through the local wireless remote control device. The monitoring system on the device performs remote monitoring operation, and the operation mode is flexible and convenient.
