Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an anti-sway hoisting box for elevators. Background Technology

[0002] The hoist cabin, also known as a suspended cage or suspended platform, is the core load-bearing component of a construction hoist, primarily used for the vertical transportation of personnel and materials. Its design must balance safety, stability, and functionality. As the core load-bearing component, its structural design directly affects the equipment's safety and operational stability. It mainly consists of a steel frame structure, protective devices, guiding mechanisms, a safety control system, and auxiliary components. It is constructed from high-strength steel welded together to ensure overall rigidity and resistance to deformation. Steel wire mesh or metal plates are installed around the perimeter to prevent materials from falling and injuring personnel, while also ensuring visibility inside. A safety rail is installed at the top for operators to grip, enhancing safety during high-altitude operations.

[0003] Traditional hoist cabins are prone to swaying due to external and human factors during use, which affects construction operations and poses safety risks. In existing technologies, guide wheels are installed on both sides of the cabin, and the cabin is limited by the external wall to achieve a stabilizing effect. However, this method is not suitable when carrying out construction work on walls outside the building that are much wider than the width of the cabin. Therefore, we propose an anti-sway cabin for hoists. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-sway hoisting box for elevators to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-sway hoisting box for an elevator, comprising a hoisting box;

[0006] A negative pressure assembly includes a bracket, one end of which is fixedly connected to a fan hood, one side of which is fixedly connected to a soft rubber ring, and the other side of which is fixedly connected to an exhaust pipe. A fixing frame is fixedly connected to the inner wall of the exhaust pipe, and a motor is fixedly connected to one side of the fixing frame. The output shaft of the motor passes through the fixing frame and is rotatably connected to a fan blade.

[0007] The bonding assembly includes a fixed sleeve, one side of which is fixedly connected to one side of the hanging box. An electric push rod is fixedly fitted inside the fixed sleeve. One end of a bracket is fixedly fitted to the side surface of the output end of the electric push rod. A limiting piece is fixedly connected to the output end of the electric push rod. A limiting groove is formed on the side surface of the limiting piece. A movable sleeve is slidably fitted onto the side surface of the limiting piece. A limiting strip adapted to the limiting groove is fixedly connected to the inner wall of the movable sleeve. A hinge seat is fixedly connected to one side of the movable sleeve. A spring is fixedly connected to the side of the hinge seat opposite to the limiting piece. A bonding wheel for wall contact is hinged inside the hinge seat. In use, the motor is started by switching on the control box, causing the motor's output end to drive the fan blades to rotate, causing air to flow from the soft rubber ring towards the exhaust pipe. Then, the electric push rod is started until the bonding wheel contacts the wall. At this point, because the soft rubber ring is close to the wall, the negative pressure created by the airflow causes the soft rubber ring to exert force on the wall, thus allowing the soft rubber ring to... When the soft rubber ring is fully attached to the wall, the attachment wheel forms a flexible connection with the limiting plate via a spring. Under negative pressure, the fan cover and the soft rubber ring pull the hoisting box closer to the wall. At this point, the spring compresses, and as the hoisting box rises and falls, the soft rubber ring adheres to the wall under negative pressure, while the attachment wheel rotates along the wall. This ensures balance and stability during the hoisting box's ascent and descent. Because the hoisting box exerts a force on the wall through negative pressure, it reduces swaying caused by personnel moving inside the hoisting box, construction work, or wind. The negative pressure component creates a force on the hoisting box from the outside towards the wall, creating a mutual traction force between the hoisting box and the wall. This prevents swaying caused by environmental and human factors, thus improving the safety and efficiency of construction. The attachment component allows the attachment wheel to slide along the depth of the electric push rod, enabling the soft rubber ring to effectively adhere to the wall under negative pressure. The sliding sleeve and attachment wheel provide space for eliminating gaps between the soft rubber ring and the wall, serving a coupling function.

[0008] Preferably, a control box is fixedly connected to one inner wall of the hanging box, a guide pipe is fixedly connected to the other end of the exhaust pipe, and a diagonal brace is fixedly connected to one side of the bracket, with the other end of the diagonal brace fixedly connected to one side of the hood.

[0009] Preferably, the guide tube is used to guide the wind direction to an oblique downward, the diagonal brace is used to provide support for the bracket and the wind cover, and the control box is electrically connected to the motor and the electric push rod.

[0010] Preferably, the soft rubber ring adheres to the wall surface through the negative pressure generated by the rotation of the fan blades.

[0011] Preferably, the movable sleeve is limited by a limiting strip and a limiting groove to slide along the longitudinal direction of the electric push rod.

[0012] Preferably, the bonding wheel rotates along the wall as the hoisting box rises and falls, and the bonding wheel is softly connected to the output end of the electric push rod via a spring.

[0013] Preferably, the number of the bonding components is two, and they are distributed on the opposite side of the hanging box.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This anti-sway hoisting box for a lifting platform...

[0015] (1) By forming negative pressure through negative pressure components, the gantry is subjected to an external force on the wall under negative pressure, which causes mutual traction between the gantry and the wall, thereby avoiding the gantry shaking caused by environmental and human factors, thus improving the safety and efficiency of construction.

[0016] (2) By using the bonding component, the bonding wheel can slide along the longitudinal direction of the electric push rod, so that the soft rubber ring can effectively adhere to the wall surface under negative pressure. The sliding movable sleeve and bonding wheel provide the space for the soft rubber ring and the wall surface to eliminate gaps, thus playing a coupling role. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model embodiment provides an anti-sway hoist box for a lifting platform, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a hanging box 1;

[0025] The negative pressure component 2 includes a bracket 201. One end of the bracket 201 is fixedly connected to a fan hood 202. A soft rubber ring 203 is fixedly connected to one side of the fan hood 202. An exhaust pipe 204 is fixedly connected to the other side of the fan hood 202. A fixing frame 205 is fixedly connected to the inner wall of the exhaust pipe 204. A motor 206 is fixedly connected to one side of the fixing frame 205. The output shaft end of the motor 206 passes through the fixing frame 205 and is rotatably connected. A fan blade 207 is fixedly connected to the output shaft end of the motor 206.

[0026] The bonding component 3 includes a fixed sleeve 301, one side of which is fixedly connected to one side of the hanging box 1. An electric push rod 302 is fixedly fitted inside the fixed sleeve 301. One end of a bracket 201 is fixedly fitted to the side surface of the output end of the electric push rod 302. A limiting piece 303 is fixedly connected to the output end of the electric push rod 302. A limiting groove 304 is formed on the side surface of the limiting piece 303. A movable sleeve 305 is slidably fitted to the side surface of the limiting piece 303. A limiting strip 306, adapted to the limiting groove 304, is fixedly connected to the inner wall of the movable sleeve 305. A hinge seat 309 is fixedly connected to one side of the movable sleeve 305. A spring 307 is fixedly connected to the side of the hinge seat 309 opposite to the limiting piece 303. A bonding wheel 308 for wall contact is hinged inside the hinge seat 309. During use, the motor 206 is started by the switch of the control box 6, causing the output end of the motor 206 to... The drive fan blade 207 rotates, causing air to flow from the soft rubber ring 203 towards the exhaust pipe 204. Then, the electric push rod 302 is activated until the contact wheel 308 contacts the wall. At this time, because the soft rubber ring 203 is close to the wall, the negative pressure formed by the air flow causes the soft rubber ring 203 to exert force on the wall, thus making the soft rubber ring 203 adhere to the wall. Since the contact wheel 308 is softly connected to the limiting piece 303 through the spring 307, when the soft rubber ring 203 is completely adhered to the wall, the fan cover 202 and the soft rubber ring 203 pull the hanging box 1 closer to the wall under the negative pressure. At this time, the spring 307 is compressed. As the hanging box 1 rises and falls, the soft rubber ring 203 adheres to the wall under the negative pressure, while the contact wheel 308 rotates along the wall, making the hanging box 1 balanced and stable during the rising and falling process. Since the hanging box 1 exerts force on the wall through the negative pressure, the swaying caused by personnel walking, construction, or wind in the hanging box 1 is reduced.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a control box 6 is fixedly connected to one inner wall of the hanging box 1, and a guide pipe 5 is fixedly connected to the other end of the exhaust pipe 204. A diagonal brace 4 is fixedly connected to one side of the bracket 201, and the other end of the diagonal brace 4 is fixedly connected to one side of the hood 202.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the guide tube 5 is used to guide the wind direction to the downward angle, the diagonal brace 4 is used to support the bracket 201 and the wind cover 202, the control box 6 is electrically connected to the motor 206 and the electric push rod 302, and the negative pressure component 2 forms a negative pressure, so that the hanging box 1 is subjected to an outward force on the wall under the negative pressure, so that the hanging box 1 and the wall form a mutual traction force, thereby avoiding the shaking of the hanging box 1 caused by environmental and human factors, thereby improving the safety and efficiency of construction personnel; through the bonding component 3, the bonding wheel 308 can slide along the longitudinal direction of the electric push rod 302, so that the soft rubber ring 203 can effectively bond to the wall under the negative pressure. The sliding movable sleeve 305 and the bonding wheel 308 provide the space for the soft rubber ring 203 to eliminate the gap between it and the wall, playing a coupling role.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the soft rubber ring 203 adheres to the wall surface through the negative pressure generated by the rotation of the fan blade 207.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the movable sleeve 305 is limited by the limiting strip 306 and the limiting groove 304 to slide along the longitudinal direction of the electric push rod 302.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bonding wheel 308 rotates along the wall as the hoisting box 1 rises and falls, and the bonding wheel 308 is softly connected to the output end of the electric push rod 302 through the spring 307.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, there are two bonding components 3, which are distributed on the opposite side of the hanging box 1.

[0033] Working principle: During use, the motor 206 is started by the switch on the control box 6, causing the output of the motor 206 to drive the fan blades 207 to rotate. This causes air to flow from the soft rubber ring 203 towards the exhaust pipe 204. Then, the electric push rod 302 is activated until the bonding wheel 308 contacts the wall. At this time, because the soft rubber ring 203 is close to the wall, the negative pressure formed by the air flow causes the soft rubber ring 203 to exert a force on the wall, thus making the soft rubber ring 203 adhere to the wall. Because the bonding wheel 308 has a spring-loaded mechanism... Spring 307 and limiting plate 303 form a soft connection, so that when soft rubber ring 203 is completely attached to the wall, wind cover 202 and soft rubber ring 203 pull the hoisting box 1 closer to the wall under negative pressure. At this time, spring 307 is compressed. As the hoisting box 1 rises and falls, soft rubber ring 203 is attached to the wall under negative pressure, and the attachment wheel 308 rotates along the wall, so that the hoisting box 1 is balanced and stable during the rising and falling process. Since the hoisting box 1 forms a force with the wall through negative pressure, the shaking caused by personnel walking in the hoisting box 1, construction or wind is reduced.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
