[0002] The hoist consists of a cage and a guide rail frame. The cage can slide up and down on the guide rail frame to meet construction needs. During the operation of the hoist, problems such as speed loss or overload failure are inevitable, causing the cage to fall downwards. In the current technology, fall arrestors are usually used for fall protection. However, once the fall arrestor fails, the construction personnel in the cage do not have a manual emergency braking device to assist in emergency braking, which can easily cause the cage to fall completely without any obstruction, thereby increasing the safety hazards of using the cage.

[0003] Therefore, there is an urgent need for an emergency braking linkage lifting platform weighing protection device to solve the above problems. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1-7 The figure shows an emergency braking linkage lifting weighing protection device, which includes a cage 101 and two guide rails 102. The opposite sides of the cage 101 are connected to the two guide rails 102 through sliders 103. It also includes a braking assembly disposed on both sides of the cage 101 near the sliders 103 for friction braking with the guide rails 102.

[0025] The braking assembly includes a sliding plate 201 slidably connected to one side of the cage 101. Two L-shaped plates 202 are connected to one side of the sliding plate 201 via a telescopic assembly. Brake plates 203 are fixedly connected to the other ends of the two L-shaped plates 202. The side of the two brake plates 203 near the guide rail 102 has a frosted surface. The cage 101 is provided with a driving assembly for driving the two brake plates 203.

[0026] It should be noted that, through the setting of the braking component, the driving component and the pulling component work together to provide the cage 101 with an emergency braking assistance that can be manually braked inside the cage 101, in addition to the fall arrestor. This improves the safety performance of the cage 101 while reducing the safety risks caused by the failure of the fall arrestor. At the same time, under the linkage of the linkage component, the braking components located on both sides of the cage 101 brake synchronously, thereby improving the braking effect of the cage 101 in emergency situations.

[0027] It is worth noting that the specific structure and working principle of the elevator, as existing technology, have been mastered by those in the field, and will not be elaborated upon here.

[0028] Please see Figure 5 The telescopic assembly shown in the figure includes a telescopic hole 301 opened on the side of the sliding plate 201 near the brake plate 203. A telescopic rod 302 is fixedly connected between the telescopic hole 301 and the two inner walls. A telescopic plate 303 is slidably connected to the side wall of the telescopic rod 302. One side of the two telescopic plates 303 is connected to the L-shaped plate 202. Two telescopic springs 304 are sleeved on the side wall of the telescopic rod 302. The two ends of the two telescopic springs 304 are respectively connected to the telescopic plate 303 and the inner wall of the telescopic hole 301.

[0029] It should be noted here that the telescopic components provide guidance and reset for the movement of the two brake plates 203.

[0030] Please see Figure 6 The drive assembly shown in the figure includes a drive plate 401 fixedly connected to the side of the cage 101 near the brake plate 203. Two T-shaped grooves 402 are provided on one side of the drive plate 401. T-shaped plates are slidably connected to the two T-shaped grooves 402. One end of the two T-shaped plates is connected to the L-shaped plate 202.

[0031] It should be noted here that the configuration of the drive components facilitates the movement of the two brake plates 203 towards or away from each other.

[0032] Please see Figure 6 and Figure 7 The cage 101 shown in the figure is provided with a pulling assembly for pulling two brake plates 203. The pulling assembly includes two fixed plates 501 that are symmetrically arranged and fixedly connected to the inner wall of the cage 101. A storage tray 503 is connected between the two fixed plates 501 through a rotating rod 502. A pull rope 504 is wound on the storage tray 503. One end of the pull rope 504 is connected to the storage tray 503, and the other end of the pull rope 504 is connected to the sliding plate 201. A first support roller 505 is provided on the side wall of the cage 101 for supporting the pull rope 504. The fixed plate 501 is provided with a winding assembly for winding the pull rope 504.

[0033] It should be noted here that the pull component is designed to facilitate the pulling of the sliding plate 201.

[0034] Please see Figure 7 The winding assembly shown in the figure includes a winding plate 601 disposed on one side of one of the two fixed plates 501. One end of a rotating rod 502 passes through the fixed plate 501 and is connected to the winding plate 601. A torsion spring 602 is sleeved on the side wall of the rotating rod 502 located between the fixed plate 501 and the winding plate 601. The two ends of the torsion spring 602 are respectively connected to the winding plate 601 and the fixed plate 501. A connecting plate 603 is fixedly connected to the other side of the two fixed plates 501 away from the storage tray 503. The end of the rotating rod 502 away from the winding plate 601 passes through the fixed plate 501. Pin holes are opened on the side walls of the connecting plate 603 and the rotating rod 502, and pins 604 are inserted into the pin holes.

[0035] It should be noted here that the winding component can be configured to enable rapid winding of the pull cord 504.

[0036] It is worth noting that the torsion spring 602 has strong elastic force, which can provide a better clamping effect for the brake plate 203 to friction and clamp the guide rail 102.

[0037] Working principle: When in use, the hoist 101 moves up and down by sliding on the guide rails 102 on both sides, thereby meeting the construction needs at different heights.

[0038] During the long-term operation of the hoist cage 101, in order to prevent the hoist cage 101 from falling abnormally due to reasons such as stalling or overload failure, a fall arrestor is often used to protect the hoist cage 101. When the fall arrestor fails under special circumstances, the construction personnel inside the hoist cage 101 can remove the pin 604 inserted on the side wall of the rotating rod 502. After the pin 604 is removed, the rotating rod 502 will rotate under the elastic action of the torsion spring 602, which will drive the storage tray 503 to rotate. During the rotation of the storage tray 503, the pull rope 504 will be wound up, thereby driving the sliding plate 201 to move away from the drive plate 401 during the winding of the pull rope 504.

[0039] As the sliding plate 201 moves away from the drive plate 401, it will drive the two L-shaped plates 202 to move synchronously. During the movement of the two L-shaped plates 202, under the interaction force of the two T-shaped inclined grooves 402 and the T-shaped block and the guiding action of the telescopic component, the two L-shaped plates 202 will move closer to each other, thereby driving the two brake plates 203 to move closer to each other, so that the two brake plates 203 abut against the side wall of the guide rail 102. Under the linkage action of the linkage component, the two brake plates 203 on the other side will abut against the side wall of the guide rail 102. Thus, under the action of the two brake plates 203 on both sides abutting against the side wall of the guide rail 102, the friction and clamping action of the brake plates 203 on the guide rail 102 will realize the emergency braking of the cage 101. This provides the cage 101 with an emergency braking assistance that can be manually braked inside the cage 101, in addition to the fall arrestor. This improves the safety performance of the cage 101 and reduces the safety risk caused by the failure of the fall arrestor.

[0040] Example 2

[0041] Please see Figure 2 and Figure 4 This embodiment further illustrates Example 1. The cage 101 in the figure is provided with a linkage assembly for linking two brake plates 203 on both sides. The linkage assembly includes a linkage rope 701 disposed on the side of the cage 101 near the bottom. The two ends of the linkage rope 701 are respectively connected to two sliding plates 201. The cage 101 is provided with a second support roller 702 for supporting the corner of the linkage rope 701.

[0042] It should be noted here that: through the setting of the linkage component, when the pull rope 504 pulls one of the sliding plates 201 on both sides of the cage 101, it will drive the other sliding plate 201 to move by pulling the linkage rope 701, thereby realizing the linkage of the two brake plates 203 on both sides of the cage 101, thus realizing the synchronous friction braking of the guide rails 102 on both sides, thereby improving the braking effect of the cage 101 in emergency situations.

[0043] It is worth noting that the braking components on both sides of the cage 101 have the same structure, the difference being the position of the sliding plate 201 relative to the brake plate 203. (See reference...) Figure 2 and Figure 4 Since it is necessary to move the sliding plate 201 and drive the two brake plates 203 to move closer to each other through the telescopic component and the drive component, the moving direction and driving position of the sliding plate 201 are adjusted, thus realizing the synchronous movement of the brake plates 203 on both sides.

[0044] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
