Description

Technical Field

[0001] This utility model relates to a cage structure, and more particularly to a drawer-type construction hoist cage structure, which belongs to the field of construction lifting and transportation machinery technology. Background Technology

[0002] Construction hoists are lifting and transporting machines suitable for the construction of high-rise buildings, bridges, chimneys, and other structures. They are responsible for transporting personnel and goods between floors of the building. Therefore, the docking between the construction hoist cage and the building is crucial. The gap between the cage sill and the landing point on the floor must meet relevant national technical standards.

[0003] Due to the diversity of building structures, the gap between the hoist cage sill and the landing point is not constant. If the gap is too large, various methods are needed to compensate for this distance to meet technical standards. For example, building an extension platform at one end of the building (structure) can incur significant manpower and material costs; alternatively, different sized flap doors can be installed on the hoist equipment, which flip up and rest on the landing point when the hoist cage discharge door is opened, thus giving rise to hoist cage structures with flap doors. However, flap doors are limited in their length and cannot be used on a wider scale. Therefore, it is essential to design a hoist cage structure that can automatically compensate for the docking distance between the hoist cage and the building (structure), and with a compensation distance longer than that of flap doors.

[0004] A utility model patent entitled "Double-Layer Base-Type Freight Elevator" was disclosed in Chinese patent CN208249648U, published on December 18, 2018. The patent includes an elevator body, a double-layer base installed on the elevator body, and a cargo delivery drive device, which is a gear and rack drive, a wire rope drive, or a hydraulic cylinder drive.

[0005] To meet the above requirements, a new transmission approach is provided to automatically compensate for the docking distance between the hoist cage and the building (structure), thereby enabling the transportation of people and goods between the hoist cage and the building (structure). Utility Model Content

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example 1.

[0022] See Figures 1 to 6 The drawer-type construction hoist cage structure in this embodiment includes a cage structure body 1-1, a movable cage body 2-1, and a drive device 3-1 for the movable cage body 2-1.

[0023] See Figure 2 As shown, the main body of the cage structure 1-1 includes a box structure 1-2, a support rail 2-2, a running rail 3-2, a rail roller group 4-2, and a movable stop 5-2. In the main body of the cage structure 1-1, a support rail 2-2 is horizontally installed at the middle height of each side wall of the box structure 1-2. A movable stop 5-2 is installed at one end of the support rail. The movable stop 5-2 is fixed in position according to the extension length required by the cage in actual operation.

[0024] The bottom plate of the main body 1-1 of the hoisting cage is provided with two rows of running tracks 3-2. Each row of running tracks 3-2 has upper and lower running surfaces (i.e., the lower running surface 3a-2 and the upper running surface 3b-2). To ensure the left and right interchangeability of the hoisting cage, a set of track rollers 4-2 is provided on the lower running surface 3a-2 at both ends of each track. The rolling surface of the track rollers is higher than the lower running surface 3a-2 of the running track. The two ends of the track are also provided with travel limit switches, which serve as trigger points for the movable cage to stop at both ends when it moves.

[0025] The main body of the cage is equipped with positioning pins 6-2 at the four corners of the cage wall. The positioning pins 6-2 can be electrically controlled to insert and remove. After the movable cage is in place, the positioning pins 6-2 are inserted into the corresponding holes of the movable cage to prevent the movable cage from moving.

[0026] See Figure 3 As shown, the drive device 3-1 includes a drive device mounting bracket 1-3, a driven sprocket 2-3, a chain 3-3, a connector 4-3, and a drive sprocket 5-3. The drive device mounting bracket 1-3 is fixed on the bottom plate of the main body 1-1 of the cage structure. The drive device 3-1 has two sprockets, one is the drive sprocket 5-3, which is connected to the motor through a shaft, and the other is the driven sprocket 2-3. A chain 3-3 (a closed chain) is wound between the two sprockets. The upper part of the chain 3-3 is provided with a connector 4-3, which is fixedly connected to the chain 3-3. The other end of the connector 4-3 is fixedly connected to the lower part of the movable cage body 2-1.

[0027] See Figure 4 As shown, the movable cage 2-1 includes a movable cage structure 1-4, an upper running roller assembly 2-4, a lower running roller assembly 3-4, and multiple positioning holes 4-4. The movable cage 2-1 adopts an asymmetrical body distribution to ensure that the center of gravity is as close as possible to the main body of the cage structure, thereby reducing the influence of the center of gravity when the movable cage extends out of the cage. The lower running roller assembly 3-4 is provided at the bottom of the cage on the heavier side. The lower running roller assembly 3-4 moves horizontally along the running track on the bottom plate. When the center of gravity of the movable cage is inside the main body of the cage structure, the lower running surface of the running track is stressed. When the movable cage extends out of the main body of the cage structure and the center of gravity is outside, the upper running surface of the running track is stressed. The upper part of the movable cage is provided with the upper running roller assembly 2-4, which moves horizontally along the support track 2-2 on the enclosure wall. Multiple positioning holes 4-4 are provided on the movable cage structure 1-4.

[0028] When the drawer-type hoisting cage structure moves vertically to a certain height on the guide rail and stops safely, the discharge door of the hoisting cage opens. The hoisting cage electrical control system issues a command, and all the positioning pins 6-2 on the main body 1-1 of the hoisting cage structure open. The drive motor of the movable cage 2-1 starts, driving the closed chain 3-3 to rotate, thereby driving the movable cage 2-1 to move horizontally along the running track 3-2. When the movable cage 2-1 extends out of the hoisting cage to the required length, it stops running by triggering the set limit switch. At the same time, the positioning pins 6-2 open and are inserted into the corresponding holes on the movable cage 2-1. After the movable cage 2-1 is fixed safely, the inlet and outlet doors on the movable cage 2-1 can be opened manually to realize the inlet and outlet transportation of people and goods.

[0029] After the movement of people and goods is completed, the cage is closed, and the electrical control system issues a command. The positioning pin 6-2 on the main body 1-1 of the cage opens, and the drive motor of the movable cage 2-1 starts and reverses, driving the closed chain 3-3 to rotate in the opposite direction. This causes the movable cage 2-1 to move horizontally in the opposite direction along the running track 3-2. When it returns to the original position of the main body 1-1 of the cage, it triggers the corresponding travel limit switch, and the positioning pin 6-2 inserts into the corresponding hole in the movable cage 2-1. Thus, the process of moving the movable cage 2-1 in and out is completed.

[0030] Example 2 The only difference between the second embodiment and the first embodiment is that the driving device of the movable cage in the second embodiment is different from the driving device of the movable cage in the first embodiment.

[0031] In the second embodiment, the driving device 3-1 of the movable cage 2-1 is a lead screw drive.

[0032] See Figure 6 As shown, the screw drive includes a screw 2-6, a screw motor 4-6, and a movable nut 3-6. The screw 2-6 is connected to both the screw motor 4-6 and the movable nut 3-6. The screw motor 4-6 is mounted on the bottom plate of the main body 1-1 of the cage structure, and the movable nut 3-6 is mounted on the bottom of the movable cage 2-1. The horizontal movement of the movable cage 2-1 in the horizontal direction is achieved by utilizing the forward and reverse rotation principle of the screw. The other end of the screw 2-6 is connected to the end bearing bracket 1-6.

[0033] Compared with the existing technology, this utility model changes the transmission principle, which is more precise and compensates for the docking distance between the cage and the building structure, so as to realize the rapid transportation of people and goods between the cage and the building structure.
