At present, a hanging basket used on a construction site can replace a traditional scaffold, can reduce the labor intensity of workers and improve the working efficiency, and becomes necessary equipment for outer wall construction of high-rise and multi-story buildings, high-altitude transportation of buildings and the like.

The existing hanging basket is relatively simple in structure, the hanging basket is connected with a rope, and the other end of the rope is connected with a lifting device. The whole hanging basket descends along the wall surface from the top of the building, and constructors stand on the hanging basket to conduct high-place construction. The constructor is equipped with a hook which is hung on the hanging basket frame.

However, the existing construction basket devices have some disadvantages because the baskets are connected only by ropes. Therefore, the hanging basket is easy to shake at a high position. When a fault occurs, after a rope on one side of the connected hanging basket is disconnected, the hanging basket is unbalanced, so that a constructor cannot stand and hang on the hanging basket. After the rope on one side of the hanging basket is disconnected, the whole weight is born by the residual rope. Which results in successive disconnections of the remaining ropes. Causing the constructor to fall along with the basket.

Detailed Description

The embodiment of the invention provides a safety escape system for a lifting basket for building construction, which comprises a basket body 3 and two lifting arms 1 for lifting the basket body 3, as shown in figures 1 to 8. The two lifting arms 1 correspond to two sides of the hanging basket body 3, and a main steel cable 2 is connected between the lifting arms 1 and the hanging basket body 3. The main steel cable 2 extends out of the lifting arm 1 and is fixedly bound with one corner of the hanging basket body 3. The lifting arm 1 is part of a lifting device, but since lifting devices are prior art. The main function is that the hanging basket body 3 is lifted when the main steel cable 2 is stored, so the specific structure, the specific parts and the like are the same as the conventional technical means, and detailed description is not needed.

A connecting plate 4 is welded between the two lifting arms 1, and a hollow balance pipe 5 is arranged below the connecting plate 4. Balance pipe 5 is parallel with 3 length direction of hanging flower basket body, and 5 outer fixed surface of balance pipe installs two sliding sleeves 9, and two sliding sleeves 9 correspond with 3 both sides of hanging flower basket body respectively, and the welding of sliding sleeve 9 bottom has two wire rope 91, and two steel wire 91 are connected with the two angles of the corresponding side of hanging flower basket body 3. A singlechip 8 for controlling each electronic part to work is fixedly arranged at the top of the balance tube 5

Four corners of the top of the hanging basket body 3 are respectively welded with a support 10. The support 10 is strip-shaped and is spirally wound on the surface of the main steel cable 2, the lower end of the steel cable 91 is arranged along the length direction of the support 10, and the lower end of the steel cable 91 is fixedly bonded with the support 10. The sliding sleeve 9 is provided with a hook 92 through a connecting rope. The hook 92 is used to hook a worker's work clothes.

In operation, the steel wire 91 is wound around the surface of the main steel wire rope 2 along the bracket 10 in the initial stage. The wire rope 91 is in a slack state. When the main rope 2 is disconnected the rope 91 is released from the bracket 10 and tensioned. The steel wire 91 temporarily holds the basket body 3 to achieve the effect of auxiliary connection. Providing buffer time facilitates preparation for rescue by a person.

The adhesion means provided to fix the wire rope 91 to the bracket 10 is because the wire rope 91 has a limited bearing capacity. To prevent the wire rope 91 from breaking by the weight of the entire basket body 3. When the load reaches a certain level, the wire 91 is separated from the bracket 10. Thereby abandoning the hanging basket body 3 and only leaving the constructors to hang on the steel wire rope 91.

The top of the balance pipe 5 is provided with a through groove 51, two sides of the inner wall of the balance pipe 5 are respectively pivoted with a base 52, a plurality of connecting rods 53 are welded between the two bases 52, ropes 54 are symmetrically arranged in the balance pipe 5, the ropes 54 surround the outer sides of the connecting rods 53, and one end of each rope 54 is fixedly bound with one of the connecting rods 53. The other end of the rope 54 passes through the through groove 51 and is fixedly bound with the bottom of the connecting plate 4.

The end of the balance pipe 5 is welded with a motor 7, and the transmission shaft of the motor 7 is welded with the base 52. The motor 7 rotates the base 52 to retract the cord 54. And when the basket body 3 descends, the motor 7 rotates forward to pay out the rope 54. When the basket body 3 ascends, the motor 7 rotates reversely to wind the rope 54.

An electric push rod 13 is fixedly arranged on the outer surface of the balance tube 5, and the movable end of the electric push rod 13 extends into the balance tube 5. When the basket body 3 goes wrong in the lifting process, the singlechip 8 controls the electric push rod 13 to extend to enable the movable end to extend between the adjacent connecting rods 53, so that the base 52 can be limited to rotate.

The cross rod 6 is welded between the two bases 52, the cross rod 6 is hollow, the balance ball 61 is arranged at the center of the inside of the cross rod 6, springs 62 are arranged on two sides of the balance ball 61 respectively, a space is reserved between the springs 62 and the balance ball 61, one end, close to the balance ball 61, of each spring 62 is welded with a contact piece I63, the other end of each balance ball 61 is welded with the inside of the cross rod 6, a contact piece II 64 is further welded in the cross rod 6, and the contact piece I63 is in contact with the contact piece II 64 due to contraction of the springs 62. When the first contact piece 63 is contacted with the second contact piece 64, the circuit is closed, a signal is transmitted to the single chip microcomputer 8, and the single chip microcomputer 8 controls the electric push rod 13 to extend and controls the motor 7 to stop rotating.

When the balance pipe is in work, when the main steel rope 2 on one side of the hanging basket body 3 breaks, the hanging basket body 3 pulls the steel rope 91, and the whole balance pipe 5 is inclined. The balance ball 61 in the crossbar 6 rolls to the inclined side to touch the first side contact 63, and presses the side spring 62 to make the first contact 63 and the second contact 64 contact.

The air flow and the construction operation of the high-altitude operation can drive the hanging basket body and the balance pipe 5 to slightly shake back and forth. Therefore, a moving space is reserved on two sides of the balance ball 61, and the balance ball 61 is prevented from pressing the spring 62 to make the contact piece I63 contact with the contact piece II 64 when the balance tube 5 is in a horizontal state.

One side of the balance pipe 5 is connected with the lifting arm 1, the side of the lifting arm 1 is pivoted with a traction wheel 11, an auxiliary steel cable 12 is arranged on the traction wheel 11, and the auxiliary steel cable 12 bypasses the traction wheel 11 and is welded with the surface of the balance pipe 5. The auxiliary rope 12 is connected to the hoist similarly to the main rope 2. When the balance pipe 5 is inclined, the operator is pulled up by pulling the auxiliary wire 12.

Compared with the prior art, the safety escape system for the building construction lifting basket realizes the triggering effect through the matching of the balance ball 61, the spring 62, the contact piece III and the contact piece II 64, so that the electric push rod 13 locks the base to fix the rope 54 after the balance tube 5 inclines, and the balance tube 5 is forbidden to continuously descend to achieve the pulling effect. Then the steel wire rope 91, the hook 92 and the bracket 10 are matched to hook people on the hanging basket and abandon the hanging basket. Thereby reducing the weight of the suspension and only pulling on the worker. The phenomenon that the worker and the hanging basket fall together due to the fact that the hanging basket is dragged and the worker is too heavy to bear is avoided.

The end part of the balance pipe 5 is connected with an air suction bin 14, and the air suction bin 14 and the balance pipe 5 are arranged in a concentric circle mode. The entire suction box 14 can be pivoted. The suction pipe 141 is welded around the axis of the suction bin 14 at equal angles, the air outlet pipe 142 is welded on one side of the suction bin 14, the fan driven by the motor is fixedly installed in the air outlet pipe 142, and the battery for providing power for the rotation of the fan is also fixedly installed in the air outlet pipe 142. The rotation of the fan generates a negative pressure in the suction chamber 14 to make the suction chamber 14 tightly contact the building wall.

Because the worker hangs in half the sky after being in danger, the rope word rocks back and forth when pulling up the worker and can lead to the worker to strike the building wall repeatedly. Further causing injury to the victim. Therefore, the balance pipe 5 is tightly attached to the wall surface of the building in an adsorption mode, and even though a worker hangs on the steel wire rope 91, the worker still swings to a small extent. However, since the wire rope 91 is short, the swing range is light, thereby reducing the damage caused by the worker hitting the building wall surface.

The balance pipe 5 is provided with a sliding groove 55 at one side close to the air suction bin 14, the sliding groove 55 is circular, a sliding block 143 matched with the sliding groove 55 is welded at one side of the air suction bin 14, and the sliding block 143 is also circular. The sliding block 143 is matched with the sliding groove 55, so that the air suction bin 14 rotates at the end part of the balance pipe 5. The rubber blocks 144 are welded at equal angles around the axis inside the sliding block 143, and the tooth blocks 56 are welded at equal angles around the axis on the side of the inner wall of the sliding groove 55 close to the rubber blocks 144.

Referring to fig. 8, when the suction chamber 14 is sucked to the wall surface of a building and the balance pipe is lifted with a worker, the suction chamber 14 rotates clockwise, and the rubber block 144 is deformed and moved between the other two tooth blocks 56. However, the suction chamber 14 cannot be rotated counterclockwise, which would cause the rubber block 144 to jam with the tooth block 56. Therefore, the air suction pipe 141 of the air suction bin 14 rubs against the building wall when the balance pipe 5 slides down in the rescue process. Providing a certain resistance.

The suction duct 141 of the suction chamber 14 is closely attached to the wall surface of the building by generating negative pressure by the rotation of the fan in the suction chamber 14. The balance pipe 5 as a whole is kept stable during the suspension process. Avoid the balanced pipe 5 to slide by a wide margin and lead to the workman of hanging constantly striking building wall and cause the injury. Plays a certain protection role.

The whole device is suitable for the condition that the distance from the ground is too high when the building is high and the fault occurs, and people can only go up.

The working principle is as follows: in use, when the main rope 2 is disconnected the rope 91 is released from the bracket 10 and tensioned. The wire rope 91 temporarily pulls the basket body 3. Providing buffer time facilitates preparation for rescue by a person. At this time, the balance tube 5 is tilted, the balance ball 61 in the crossbar 6 rolls to the tilted side to touch the first contact 63, and the side spring 62 is pressed to close the contact circuit between the first contact 63 and the second contact 64. The singlechip 8 receives the signal, controls the electric push rod 13 to extend and controls the motor 7 to stop rotating. The electric push rod 13 is extended to make the movable end enter between the adjacent links 53, so that the base 52 can be restricted from rotating, and the rope 54 tightly pulls the balance tube 5.

Then, because the wire 91 is fixedly bonded to the bracket 10, when the load reaches a certain level, the wire 91 is separated from the bracket 10. Thereby abandoning the hanging basket body 3 and only leaving the constructors to hang on the steel wire rope 91.

Finally, the balance pipe 5 is pulled up by dragging the auxiliary steel cable 2 to realize escape.

In summary, the safety escape system for the building construction lifting basket realizes the triggering effect through the matching of the balance ball 61, the spring 62, the contact piece III and the contact piece II 64, so that the electric push rod 13 locks the base to fix the rope 54 after the balance tube 5 is inclined, and the balance tube 5 is forbidden to continuously descend to achieve the pulling effect. Then the steel wire rope 91, the hook 92 and the bracket 10 are matched to hook people on the hanging basket and abandon the hanging basket. Thereby reducing the weight of the suspension and only pulling on the worker. The phenomenon that the worker and the hanging basket fall together due to the fact that the hanging basket is dragged and the worker is too heavy to bear is avoided.

In addition, the suction duct 141 of the suction chamber 14 is brought into close contact with the wall surface of the building by generating negative pressure by the rotation of the fan in the suction chamber 14. The balance pipe 5 as a whole is kept stable during the suspension process. Avoid the balanced pipe 5 to slide by a wide margin and lead to the workman of hanging constantly striking building wall and cause the injury. Plays a certain protection role.
