Description

Technical Field

[0001] The utility model relates to the technical field of hanging baskets, and particularly relates to a hanging basket for elevator installation. Background Technique

[0002] The hanging basket for elevator installation is a carrier used to carry workers for elevator installation during elevator installation, enabling workers to support and install the elevator at high altitude. When the hanging basket is installed and used, the suspension rods at both ends are connected to the hoisting equipment on the upper side, so that the hanging basket can carry the standing of workers. In order to prevent potential safety hazards for workers inside the hanging basket, a safety rope is usually installed inside the hanging basket. The length of the safety rope is usually a fixed length, restricting the movement range of workers and affecting their work. Such a hanging basket for elevator installation is not convenient to change the length of the safety rope according to the usage requirements, thus affecting the work of workers.

[0003] After retrieval, in the prior art, the Chinese patent with the patent application number CN220078551U discloses a hanging basket for elevator installation, which solves the problem that the existing hanging basket for elevator installation is not convenient to change the length of the safety rope according to the usage requirements, affecting the work of workers. It includes a fixing plate, both sides of the upper end of the fixing plate are connected with support plates, the middle of the upper end of the support plates is connected with a lifting device, and a mounting plate is connected between the two support plates. However, there are still the following defects:

[0004] (1) In the above patent document, the support plate is used as the connection fulcrum between the hanging basket and the steel cable. When there are relatively tall personnel and items in the hanging basket, the overall center of gravity of the hanging basket will move upward. When the center of gravity of the hanging basket is higher than the connection fulcrum, the instability of the hanging basket will increase, resulting in the situation that the hanging basket will shake violently or tilt greatly when workers are working in the hanging basket, posing a safety hazard and increasing the riding risk of passengers.

[0005] In the above patent document, the hanging basket for elevator installation uses the suspended steel cable for load bearing and lifting during use. However, since the steel cable only provides an upward pulling force, the hanging basket lacks a horizontal support force point, resulting in the hanging basket shaking during suspension, affecting the workers' elevator installation work and reducing the work efficiency of the workers.

[0006] Therefore, we make improvements on this and propose a hanging basket for elevator installation. Content of the Utility Model

[0007] The object of the present utility model is to address the following problems: Currently, a support plate is used as the connection fulcrum between the hanging basket and the steel cable. When there are relatively tall personnel and items in the hanging basket, the overall center of gravity of the hanging basket will shift upward. When the center of gravity of the hanging basket is higher than the connection fulcrum, the instability of the hanging basket will increase, resulting in severe shaking or large tilting of the hanging basket when the staff is working in the hanging basket, posing a safety hazard and increasing the riding risk of the passengers. When the elevator installation hanging basket is in use, it is hoisted and lowered by the suspended steel cable. However, since the steel cable only provides an upward pulling force, the hanging basket lacks a horizontal support force point, causing the hanging basket to shake when suspended, affecting the elevator installation work of the staff and reducing the work efficiency of the staff.

[0008] In order to achieve the above object of the utility model, the present utility model provides the following technical solutions:

[0009] A hanging basket for elevator installation, comprising a base and limiting columns fixedly connected to the top wall of the base. The limiting columns are symmetrically distributed about the central axis of the base. It further includes:

[0010] A lifting assembly, fixedly connected to the top wall of the limiting column, for pulling the hanging basket to perform lifting and lowering movements. Among them, the lifting assembly includes a connecting plate fixedly connected to the top wall of the limiting column, a bearing pulley rotatably connected to the top wall of the connecting plate, and a steel cable rotatably connected to the outer wall of the bearing pulley. The bearing pulleys are symmetrically distributed about the central axis of the connecting plate;

[0011] A bearing assembly, slidably connected to the outer wall of the limiting column, for adjusting the overall center of gravity of the hanging basket when carrying people and objects;

[0012] A safety assembly, fixedly connected to the outer wall of the bearing assembly, for providing a moving safety hanging point for the safety rope;

[0013] A support assembly, slidably connected to the outer wall of the bearing assembly, for providing horizontal support to the hanging basket;

[0014] A protection assembly, rotatably connected to the top of the bearing assembly, for preventing the items carried by the hanging basket from slipping.

[0015] As a preferred technical solution of the present utility model, the bearing assembly includes a lifting hydraulic cylinder rotatably connected to the top wall of the base, a bearing seat slidably connected to the outer wall of the limiting column, and a protective railing fixedly connected to the outer wall of the bearing seat. The lifting hydraulic cylinder and the protective railing are symmetrically distributed about the central axis of the bearing seat. The lifting hydraulic cylinder pushes the bearing seat to move along the outer wall of the limiting column.

[0016] As a preferred technical solution of the present utility model, the safety assembly includes a safety bearing arm fixedly connected to the outer wall of the bearing seat, a limiting chute opened on the outer wall of the safety bearing arm, and a sliding safety buckle slidably connected to the inner wall of the safety bearing arm. The sliding safety buckle extends out of the safety bearing arm through the limiting chute.

[0017] As a preferred technical solution of the present utility model, the support assembly includes a support hydraulic cylinder rotatably connected to the outer wall of the bearing seat, a support sliding frame slidably connected to the outer wall of the bearing seat, and rubber wheels rotatably connected to the outer wall of the support sliding frame. The support hydraulic cylinder and the bearing sliding frame are symmetrically distributed about the central axis of the bearing seat, and the rubber wheels are symmetrically distributed about the central axis of the support sliding frame.

[0018] As a preferred technical solution of the present utility model, the protection assembly includes a door panel rotatably connected to the top wall of the bearing seat and a door bolt slidably connected to the inner wall of the door panel. The door panel is symmetrically distributed about the central axis of the bearing seat.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] In the solution of the present utility model:

[0021] 1. By setting the lifting hydraulic cylinder to push the bearing seat to move along the outer wall of the limit column, the overall center of gravity of the people and objects in the bearing seat is made lower than the connection point of the steel cable and the bearing pulley, realizing the adjustment of the overall center of gravity of the hanging basket, and solving the problem in the prior art that when using a support plate as the connection fulcrum between the hanging basket and the steel cable, when there are relatively tall personnel and items in the hanging basket, the overall center of gravity of the hanging basket will move upward. When the center of gravity of the hanging basket is higher than the connection fulcrum, it will increase the instability of the hanging basket, resulting in the situation that the hanging basket will shake violently or tilt greatly when the staff is working in the hanging basket, there is a safety hazard, and the riding risk of the passengers is increased.

[0022] 2. By setting the support hydraulic cylinder to push the support sliding frame to move along the outer wall of the bearing seat, the rubber wheels are made to closely adhere to the building wall, and the rubber wheels roll along the building surface during the lifting and lowering of the hanging basket, realizing the stable support of the hanging basket in the horizontal direction, and solving the problem in the prior art that when the hanging basket for elevator installation is used, it is carried and lifted by the suspended steel cable. However, since the steel cable only provides an upward pulling force and the hanging basket lacks a support force point in the horizontal direction, the hanging basket will shake when suspended, affecting the elevator installation work of the staff and reducing the work efficiency of the staff.

Specific embodiments

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0030] As Figure 1 and Figure 4 shown, this embodiment proposes a hanging basket for elevator installation, including a base 1 and limit posts 11 fixedly connected to the top wall of the base 1. The limit posts 11 are symmetrically distributed about the central axis of the base 1, and further include:

[0031] A lifting assembly, fixedly connected to the top wall of the limit post 11, for pulling the hanging basket for lifting movement. Among them, the lifting assembly includes a connecting plate 2 fixedly connected to the top wall of the limit post 11, a load-bearing pulley 21 rotatably connected to the top wall of the connecting plate 2, and a steel cable 22 rotatably connected to the outer wall of the load-bearing pulley 21. The load-bearing pulleys 21 are symmetrically distributed about the central axis of the connecting plate 2. First, use a winch to wind up the steel cable 22 to move the hanging basket to the set riding position, completing the preparation work before the hanging basket is ridden.

[0032] A load-bearing assembly, slidably connected to the outer wall of the limit post 11, for adjusting the overall center of gravity of the hanging basket when carrying people and objects;

[0033] A safety assembly, fixedly connected to the outer wall of the load-bearing assembly, for providing a moving safety hanging point for the safety rope;

[0034] A support assembly, slidably connected to the outer wall of the load-bearing assembly, for providing horizontal support for the hanging basket;

[0035] A protection assembly, rotatably connected to the top of the load-bearing assembly, for preventing the items carried by the hanging basket from slipping.

[0036] As Figure 1 , Figure 2 and Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, the bearing assembly includes a lifting hydraulic cylinder 31 rotatably connected to the top wall of the base 1, a bearing seat 3 slidably connected to the outer wall of the limiting column 11, and a protective railing 32 fixedly connected to the outer wall of the bearing seat 3. The lifting hydraulic cylinder 31 and the protective railing 32 are symmetrically distributed about the central axis of the bearing seat 3. The lifting hydraulic cylinder 31 pushes the bearing seat 3 to move along the outer wall of the limiting column 11. By controlling the lifting hydraulic cylinder 31 to push the bearing seat 3 to move along the outer wall of the limiting column 11, the overall center of gravity of the people and items in the bearing seat 3 is made lower than that of the steel cable 22 on the bearing pulley 21, realizing the center of gravity adjustment of the overall hanging basket.

[0037] As Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the safety assembly includes a safety bearing arm 5 fixedly connected to the outer wall of the bearing seat 3, a limiting chute 51 opened on the outer wall of the safety bearing arm 5, and a sliding safety buckle 52 slidably connected to the inner wall of the safety bearing arm 5. The sliding safety buckle 52 extends outward from the safety bearing arm 5 through the limiting chute 51. The safety rope buckle of the staff is fixedly connected to the sliding safety buckle 52 to complete the further safety protection of the staff. And since the sliding safety buckle 52 can slide along the inner wall of the safety bearing arm 5, the activity range of the staff is expanded. At the same time, since the limiting chutes 51 can be smoothly connected, the situation where the sliding safety locks interfere with each other when multiple staff work in the hanging basket is avoided.

[0038] As Figure 1 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the support assembly includes a support hydraulic cylinder 4 rotatably connected to the outer wall of the bearing seat 3, a support carriage 41 slidably connected to the outer wall of the bearing seat 3, and a rubber wheel 42 rotatably connected to the outer wall of the support carriage 41. The support hydraulic cylinder 4 and the support carriage are symmetrically distributed about the central axis of the bearing seat 3. The rubber wheels 42 are symmetrically distributed about the central axis of the support carriage 41. By starting the support hydraulic cylinder 4 to push the support carriage 41 to move along the outer wall of the bearing seat 3, the rubber wheels 42 are made to closely adhere to the building wall. During the lifting and lowering of the hanging basket, the rubber wheels 42 roll along the building surface to provide stable support for the hanging basket in the horizontal direction.

[0039] As Figure 1 and Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the protection component includes a door panel 6 rotatably connected to the top wall of the carrier 3 and a bolt 61 slidably connected to the inner wall of the door panel 6. The door panels 6 are symmetrically distributed about the central axis of the carrier 3. The sliding bolt 61 unlocks the door panel 6, and then the door panel 6 is opened to allow the staff and equipment to move into the carrier 3. The door panel 6 is closed and the bolt 61 is locked to complete the preliminary safety protection of the staff and equipment.

[0040] Specifically, when the device is in use: First, use the winch to wind up the steel cable 22 to move the hanging basket to the set riding position to complete the preparation work before the hanging basket is ridden. The sliding bolt 61 unlocks the door panel 6, and then the door panel 6 is opened to allow the staff and equipment to move into the carrier 3. The door panel 6 is closed and the bolt 61 is locked to complete the preliminary safety protection of the staff and equipment. The safety rope buckle of the staff is fixedly connected to the sliding safety buckle 52 to complete the further safety protection of the staff. And because the sliding safety buckle 52 can slide along the inner wall of the safety bearing arm 5, the activity range of the staff is expanded. At the same time, because the limit sliding grooves 51 can be smoothly communicated, the situation where the sliding safety locks interfere with each other when multiple staff work in the hanging basket is avoided. Then, according to the actual loading situation of people and items in the hanging basket, control the lifting hydraulic cylinder 31 to push the carrier 3 to move along the outer wall of the limit column 11, so that the overall center of gravity of the people and items in the carrier 3 is lower than the connection point of the steel cable 22 and the load-bearing pulley 21, realizing the center-of-gravity adjustment of the whole hanging basket. Start the support hydraulic cylinder 4 to push the support carriage 41 to move along the outer wall of the carrier 3, so that the rubber wheels 42 are closely attached to the building wall. During the lifting and lowering of the hanging basket, the rubber wheels 42 roll along the building surface to provide stable horizontal support for the hanging basket.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
