Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a safety basket for high-altitude operation in building construction and a use method thereof. BACKGROUND

[0002] The safety basket is an important tool for high-altitude operation in building construction, mainly used for tasks such as curtain wall installation and external wall cleaning. It is a cantilever mechanism erected on a building or structure, and the suspended platform is driven by a lifting mechanism to run up and down along the facade of the building or structure. In order to prevent the safety basket from colliding with the construction wall and reducing the safety of the safety basket, the existing safety basket wheel is installed with a wall-following wheel on the side close to the wall. With the progress of society, the style of the wall-following wheel is constantly updated.

[0003] The patent with publication number CN113089996A discloses a safety basket against sudden falling, which realizes that when the basket encounters a protruding wall surface during the process of rising and falling, the roller contacts the wall to block the safety basket from colliding with the wall, and the triangular turntable is turned to pass over the protruding surface of the wall, avoiding the occurrence of safety accidents caused by the turning of the basket. Although this patent can avoid the direct collision between the safety basket and the wall, when the roller acts on the wall, it is a non-elastic collision, and since no buffer is provided, the impact force on the safety basket is large when the roller collides with the wall.

[0004] The patent with publication number CN113605668B discloses a safety basket against sudden falling, which realizes that when the basket body shakes and touches the building, the shock-absorbing block is extruded, the connecting rod is further pushed, and the moving block moves away from each other along the slide, the two moving blocks are pulled by the shock-absorbing spring, and the impact force generated when the shock-absorbing block touches the building is absorbed, avoiding damage to the basket body and the building. Although this patent can reduce the impact force when colliding, when the shock-absorbing block cannot be connected with the wall, the shock-absorbing block is easily worn out when the basket collides with the wall during the process of rising and falling.

[0005] Therefore, how to design a safety basket that can reduce the impact force between the safety basket and the wall, realize sliding friction with the wall, and reduce equipment wear and tear has become a technical problem that needs to be solved by those skilled in the art. SUMMARY

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0048] In order to make the above-mentioned purposes, features and advantages of the application more obvious and easy to understand, the application will be further described in detail below with reference to the drawings and specific embodiments.

[0049] Reference Figure 1The application provides a safe hanging basket for high-altitude operation in building construction, which is applied to the high-altitude operation environment in building construction, can realize the impact force between the buffer hanging basket body 1 and the construction wall, reduces the abrasion of the equipment in use, prolongs the service life of the safe hanging basket and improves the use safety of the workers. The specific structure comprises a hanging basket body 1, a support frame 2, a first pulley frame 3, a second pulley frame 4, a tension pulley frame 5, a first pulley 6, a second pulley 7, a tension pulley 8, a buffer assembly and a track 9. The hanging basket body 1 is provided with a hoist (not shown in the figure), a safety lock (not shown in the figure), an electrical control box (not shown in the figure) and the like, and is provided with a working steel wire rope and a safety steel wire rope, so as to realize the lifting and lowering process of the hanging basket body 1. This part belongs to the prior art and will not be repeated here. The support frame 2 is installed on the outer side wall of the side of the hanging basket body 1 close to the construction wall, and a plurality of first pulley frames 3, a plurality of second pulley frames 4 and a plurality of tension pulley frames 5 are installed on the support frame 2. The first pulley 6, the second pulley 7 and the tension pulley 8 are respectively rotationally connected to the first pulley frame 3, the second pulley frame 4 and the tension pulley frame 5. The first pulley 6 and the second pulley 7 are respectively located on the side of the support frame 2 away from the hanging basket body 1 and the side of the support frame 2 close to the hanging basket body 1. The tension pulley 8 is provided with two and is respectively arranged at the upper and lower ends of the support frame 2. The first pulley frame 3 has a tendency to drive the first pulley 6 to move away from the hanging basket body 1 under the action of the buffer assembly. The first pulley 6, the second pulley 7 and the tension pulley 8 are located on the circumferential side of the support frame 2. The track 9 is sleeved outside the first pulley 6, the second pulley 7 and the tension pulley 8. The track 9 is kept in a tight state under the action of the tension pulley 8. At this time, the first pulley 6, the second pulley 7 and the tension pulley 8 are respectively frictionally connected with the track 9. The track 9 can rotate bidirectionally around the support frame 2.

[0050] When in use, the distance between the hanging basket body 1 and the construction wall is adjusted, the outer side wall of the track 9 close to the first pulley 6 is connected with the construction wall. Since the track 9 can rotate around the support frame 2, the hanging basket body 1 always maintains a certain distance from the construction wall during the lifting and lowering process, and the track 9 is connected with the construction wall without relative sliding, which can effectively reduce the equipment abrasion caused by sliding friction. When the hanging basket body 1 moves towards the construction wall under the action of wind and other external forces, the tendency of the buffer assembly and a part of the impact force are offset, so as to slow down the impact force between the safe hanging basket and the construction wall, thereby providing a safe operation platform for the operator.

[0051] It should be explained that, due to the provision of the tension pulley 8, the contact surface of the track 9 and the construction wall can realize the effect of being concave, so as to make the track 9 contact with the uneven construction wall, thereby improving the use range of the hanging basket body 1 of the application.

[0052] Refer toFigures 2-3 As shown, the buffer assembly comprises a plurality of sets of extrusion blocks 10 arranged in columns and slidingly connected to the support frame 2 in the vertical direction, each set of extrusion blocks 10 comprises two oppositely arranged extrusion blocks 10, and an extrusion cavity is arranged in each set of extrusion blocks 10, i.e. the two oppositely arranged extrusion blocks 10 are spliced to form an extrusion cavity. In addition, the buffer assembly further comprises an extrusion member arranged on the support frame 2, which is used to drive each set of extrusion blocks 10 to move close to each other, i.e. the extrusion member has a tendency to drive each set of extrusion blocks 10 to move close to each other.

[0053] The first pulley frame 3 comprises a first support 301, a connecting rod 302 and a pushing block 303. The first support 301 is rotationally connected to the first pulley 6, the connecting rod 302 is fixedly connected to the first support 301 near the side wall of the basket body 1, the connecting rod 302 is slidingly connected to the support frame 2 in the horizontal direction and slidingly penetrates the extrusion cavity, the pushing block 303, the first support 301 and the connecting rod 302 are arranged one by one, the pushing block 303 is fixedly sleeved on the side wall of the connecting rod 302, the pushing block 303 is matched with the extrusion cavity, the pushing block 303 is slidingly connected to the extrusion cavity, when the pushing block 303 moves towards the basket body 1, each set of extrusion blocks 10 moves in the direction away from each other, and when the pushing block 303 moves towards the basket body 1, each set of extrusion blocks 10 moves close to each other under the action of the extrusion member until abutting against each other.

[0054] When the external force pushes the hanging basket body 1 to move towards the construction wall, the caterpillar belt 9 contacts with the construction wall, and drives the first pulley 6 to move towards the support frame 2. During the process, the pushing block 303 interacts with the extrusion cavity, the pushing block 303 overcomes the force of the extrusion piece on the extrusion block 10, so that each group of extrusion blocks 10 moves away from each other, and each group of extrusion blocks 10 extrudes each other, and the multiple extrusion blocks 10 form a vertical force between them, so that the vertical distance between the multiple first pulleys 6 is continuously increased. During the above process, since the force of the extrusion piece needs to be overcome, the first pulley 6 can be buffered when moving towards the hanging basket body 1, and since the vertical distance between the multiple first pulleys 6 is increased, the contact area between the caterpillar belt 9 and the wall is increased, which can reduce the pressure on the caterpillar belt 9, thereby improving the stability of the hanging basket body 1. This working condition is more suitable for the construction working environment of glass curtain walls and other fragile buildings. When the external force disappears, each group of extrusion blocks 10 approaches each other under the action of the extrusion piece. During the process of each group of extrusion blocks 10 approaching each other, a component force is provided to the pushing block 303 to move towards the construction wall, so that the first pulley 6 can move away from the support frame 2. At this time, the vertical distance between the multiple first pulleys 6 will be reduced, so that the contact area between the caterpillar belt 9 and the construction wall is reduced. The reduction of the contact area is beneficial to reduce the friction between the caterpillar belt 9 and the construction wall during the ascending or descending process of the hanging basket body 1, so as to avoid the situation that the hanging basket body 1 overturns due to excessive friction.

[0055] The second pulley frame 4 is a fixed frame, the second pulley 7 is rotationally connected with the fixed frame, and the end of the fixed frame away from the second pulley 7 is fixedly connected with the support frame 2.

[0056] The tension pulley frame 5 comprises a support rod 501, a piston rod 502, a piston sleeve 503 and a third compression spring 504. One end of the support rod 501 is hingedly connected with the support frame 2, and the other end of the support rod 501 is rotationally connected with the tension pulley 8. One end of the piston rod 502 is slidably sleeved in one end of the piston sleeve 503, and the other end of the piston rod 502 and the other end of the piston sleeve 503 are both fixedly connected with a limiting pin 505. The third compression spring 504 is sleeved on the circumferential side of the piston rod 502 and the piston sleeve 503, and the two ends of the third compression spring 504 are respectively abutted with the two limiting pins 505. The other end of the piston rod 502 is hingedly connected with the middle part of the support rod 501, and the other end of the piston sleeve 503 is hingedly connected with the support frame 2. The support rod 501 and the piston rod 502 are arranged in a “Z” shape. Through the arrangement of the piston rod 502 and the piston sleeve 503, the total length of the piston rod 502 and the piston sleeve 503 is adjustable, so that the distance between the tension pulley 8 and the support frame 2 is adjustable. Since the third compression spring 504 is arranged, the tension pulley 8 can always abut against the caterpillar belt 9, and the caterpillar belt 9 can be kept in a taut state.
