Each pair of springs A24 is in a compressed state.

When it is necessary to use the present invention to hoist and install the prefabricated wall 44 and dock it with the bottom plate, the internal thread sleeves 10 in the two connecting mechanisms 4 are respectively tightly nested and screwed to the two ends of the prefabricated wall 44. Then, the assembled wall body 44 connected with the two connection mechanisms 4 is hoisted by the steel wire rope 1 for suspension.

After the assembled wall 44 is suspended, observe whether the assembled wall 44 is perpendicular to the base plate and whether the lower end surface of the assembled wall 44 is parallel to the base plate. If the assembled wall 44 is not perpendicular to the base plate and the assembled wall 44 If the lower end surface is not parallel to the bottom plate, it means that the center of gravity of the assembled wall body 44 is not located on the vertical axis where the steel wire rope 1 or the rotating shaft 29 is located. At this time, the internal thread sleeves 10 in the two connecting mechanisms 4 are knocked horizontally by the hammer along the direction perpendicular to the beam 3, and the two internal thread sleeves 10 respectively drive the round blocks 7 on the corresponding cylinders 8 in the corresponding round sleeves 6. Move horizontally along the direction perpendicular to the beam 3 and drive the center of gravity of the assembled wall 44 to move horizontally along the direction perpendicular to the beam 3 to the vertical axis where the rotating shaft 29 or the wire rope 1 is located, so that the assembled wall 44 is perpendicular to the bottom plate .

Then, the internal thread sleeves 10 in the two connecting mechanisms 4 are knocked horizontally with a hammer along the direction parallel to the crossbeam 3, and the two internal thread sleeves 10 drive the round blocks 7 on the corresponding cylinders 8 to move along the inner edges of the corresponding round sleeves 6 respectively. Move horizontally in the direction parallel to the beam 3 and drive the center of gravity of the assembled wall 44 to move horizontally in the direction horizontal to the beam 3 to the vertical axis where the rotating shaft 29 or the wire rope 1 is located, so that the lower end surface of the assembled wall 44 is in contact with the bottom plate parallel.

So far, the prefabricated wall 44 is perpendicular to the bottom plate and the lower end surface of the prefabricated wall 44 is parallel to the bottom plate, and the radius of the steel wire rope 1 wound by the sleeve on the lower end face of the prefabricated wall body 44 is equal to the radius of the corresponding steel bar 45 on the bottom plate around the steel wire rope 1 , and there is a certain axial distance around the steel wire rope 1 between the sleeve on the lower end surface of the assembled wall body 44 and the corresponding steel bar 45 on the bottom plate.

Then, through the air pump 40 times to quickly deliver air to the weight 30, during each time the air is delivered to the weight 30, the high-pressure air entering the weight 30 drives the arc block 37 to wind the wire rope through the piston 34 and the connecting rod 36 1 movement, the arc block 37 drives the disc 12 to rotate synchronously around the wire rope 1 through a number of ratchet teeth matched with the upper ratchet groove 38. Due to the relationship between the action force and the reaction force, the weight 30 is in the chute A13 under the action of the reaction force. Moving in the opposite direction around the wire rope 1, the spring C35 is compressed. The disc 12 rotating around the steel wire rope 1 drives the assembled wall body 44 to rotate around the steel wire rope 1 to a certain extent synchronously through the beam 3 of the tripod 2 and the connection mechanism 4 connected with the two steel bars 45 on the assembled wall body 44 .

In the time gap between the end of each gas delivery to the weight 30 and the second gas delivery to the weight 30, the piston 34 in the weight 30 is driven by the connecting rod 36 under the reset action of the spring C35. The arc block 37 resets relative to the weight block 30, and the arc block 37 presses the ratchet it passes into the chute B16, and the ratchet pressed into the chute B16 by the arc block 37 passes through the corresponding slider 17, the corresponding rack 18, The gear A19 and the gear B20 drive the ring gear 21 to rotate to a certain extent, and the three pairs of springs A24 are deformed accordingly, and the shifting block A22 on the ring gear 21 does not interact with the shifting block B27.

In this way, the high-pressure air is input into the heavy block 30 for several times, so that the arc block 37 drives the assembled wall 44 to continuously swing around the steel wire rope 1 for several times under the impact of the high-pressure air, and finally makes the lower end of the assembled wall 44 The sleeves respectively reach above the corresponding reinforcement bars 45 on the base plate.

When the sleeve at the lower end of the assembled wall body 44 reaches the corresponding reinforcing bar 45 on the base plate completely and one by one, start the motor 43, and the motor 43 passes through the gear D42, the gear C41, the rotating shaft 29, the fork 25, the arc rod 26 and the spring. B28 drives the shifting block B27 to quickly interact with the shifting block A22 and drives the ring gear 21 to rotate in the disc 12 to a certain extent. Sliding to the outside of the chute B16, so that the ratchet in the ratchet groove 38 on the arc block 37 completely enters the ratchet groove 38 on the arc block 37 and prevents the reset of the arc block 37 in the spring C35 relative to the weight 30, Since the weight 30 still slides around the steel wire rope 1 relative to the disk 12 under the action of inertia at this time, the weight 30 drives the disk through the spring C35, the piston 34, the connecting rod 36, the arc block 37 and the ratchet fully inserted into the ratchet groove 38. 12 and the prefabricated body of wall 44 installed under the beam 3 stop around the rotation of the wire rope 1 and keep the sleeve at the lower end of the prefabricated body of wall 44 corresponding to the reinforcing bar 45 on the base plate.

Then, the prefabricated wall 44 is dropped, so that the sleeves on the prefabricated wall 44 are respectively nested on the corresponding steel bars 45 on the bottom plate to complete the docking.

After the prefabricated wall 44 completes the connection with the base plate, the internal thread sleeves 10 on the two connecting mechanisms 4 are respectively rotated away from the two steel bars 45 on the upper end of the prefabricated wall 44, and then the motor 43 is started, and the motor 43 passes through a The series transmission drives the dial block B27 to reset, and the ring gear 21 drives all the sliders 17 to completely shrink into the chute B16 through a series of transmissions under the reset action of the three pairs of springs A24 to reset and reset the arc block 37 relative to the weight 30 Can't be blocked. The arc block 37 resets relative to the weight 30 under the reset action of the spring C35.

The spring B28 on the arc rod 26 effectively buffers the impact of the shifting block B27 and the shifting block A22 when the shifting block B27 and the shifting block A22 meet.

The pendulum adjustment mechanism 11 quickly inflates the weight 30 and drives the suspended hoisted assembled wall 44 to rotate and adjust its position through the arc 37 around the steel wire rope 1. During the position adjustment process of the assembled wall 44, the weight 30 and the arc 37 reversely moves around the steel wire rope 1 under the action of internal high-pressure gas, and the assembled wall 44 is adjusted in position under the drive of the arc block 37, so that the sleeve at the bottom of the wall corresponds to the corresponding steel bar 45 on the bottom plate, thereby Complete the perfect butt joint between the wall and the bottom plate. In the process of adjusting the position of the prefabricated wall 44 in the suspended hoisting state, the rotational adjustment of the position of the prefabricated wall 44 in the suspended hoisting state can be realized without manual participation, and the safety is high.

There is a recording chip in the disk 12 of the pendulum mechanism 11, and the chip can systematically record the relationship between the signal of the high-pressure air input in the weight 30, the rotation range of the disk 12, and the weight of the assembled wall body 44 and compare them. Intelligent analysis is carried out to form a database, so as to realize the accurate collection of the relationship between the subsequent high-pressure air signal input into the weight 30 , the rotation range of the disk 12 and the weight of the assembled wall 44 .
