Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of safety rescue equipment, and in particular relates to a rescue device for feet caught in gaps on subway platforms. Background Art
[0002] The subway gap refers to the narrow gap between the subway train and the platform, which usually exists due to design requirements, vehicle size and platform height. When a passenger steps into the gap between the empty train and the platform screen door, the three principles of minimizing passenger injuries, not damaging the train and the platform screen door equipment, and optimizing the handling efficiency should be followed. There are some shortcomings in the existing rescue tools, such as the heavy lifting air cushion and the need for multiple people to operate, the small force-bearing surface of the electric hydraulic universal shearing pliers and the manual hydraulic universal shearing pliers, and the equipment is easily damaged by manual operation. Therefore, there is an urgent need for a tool that can solve the rescue problem, which can flexibly adapt to different gap sizes and shapes, and has the characteristics of lightweight, portability and easy operation, while ensuring sufficient strength and stability. Utility Model Content
[0003] In order to overcome the problems existing in the prior art, the utility model aims to provide a rescue device for feet caught in gaps on subway platforms.

[0014] Preferably, one end of the top plate is connected to the driving end of the telescopic assembly, the other end of the top plate extends to below the main plate, and a pad is provided on the other end of the top plate facing the subway.
[0015] Preferably, the top plate is pear-shaped, the narrow side of the top plate is connected to the driving end of the telescopic assembly, the wide end of the top plate extends to below the main board, and the pad is arranged on the side of the wide end of the top plate facing the subway.
[0016] Preferably, the hydraulic assembly comprises a cylinder body and a pressure rod, and the pressure rod is drivingly connected to the cylinder body;
[0017] Supports are also provided on both sides of the cylinder body, and the cylinder body is stably placed on the ground through the supports on both sides.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] The utility model drives the telescopic assembly through the hydraulic assembly, which can respond quickly and rescue the passengers whose feet are trapped from the gap, greatly shortening the rescue time and improving the rescue efficiency. At the same time, the design of the fixed bracket ensures that the device can be stably fixed on the edge of the platform, avoiding shaking or displacement during the rescue process, ensuring the safety of the rescue process, and the device can be applied to platform gaps of different widths and depths, with strong adaptability and versatility, and can meet the rescue needs in different situations. Moreover, the design of the top plate fully considers the protection of the subway car. In addition, the entire device has a simple structure and is easy to operate.

[0024] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0026] Example 1
[0027] This embodiment discloses a rescue device for foot-trapping gaps in subway platforms. Figure 1-Figure 2 As shown, it mainly includes a fixed bracket 1, a top plate 2, a telescopic component 3 and a hydraulic component 4. These components work together to provide fast and effective rescue in the event of a foot-trapping accident in the gap between subway platforms.
[0028] Specifically, the fixed bracket 1 serves as a supporting part, and its main function is to fix the telescopic component 3 and cooperate with the subway platform. The fixed bracket 1 includes a main board 10. The main board 10 is rectangular and is placed vertically at the edge of the subway platform. Support plates 11 are arranged on both sides thereof. The support plates 11 extend outward toward one side of the main board 10 to form a snap-fit structure that matches the platform gap. A fixed sleeve 12 is arranged in the center of the other side of the main board 10 for installing the telescopic component 3. The telescopic component 3 is installed in the fixed sleeve 12 as a driving device. Since a through hole 13 is opened in the middle of the main board 10, the driving end of the telescopic component 3 extends out. In addition, the top plate 2 is installed at the driving end of the telescopic component 3. In order to ensure its own strength, the top plate 2 is made of metal. The other side of the top plate 2 is pressed against the subway car.
[0029] During the working process, first, when an accident occurs where a passenger's foot is caught in the gap between the subway platform and the train, the rescuer quickly moves the subway platform gap foot-caught rescue device to the location where the accident occurred. At this time, the fixing bracket 1 is placed on one side of the subway platform, and is engaged with the edge of the subway platform through the support plates 11 on both sides, ensuring that the entire device is stably fixed on the edge of the platform.
[0030] Then, the hydraulic assembly 4 starts to work. When the pressure rod 41 in the hydraulic assembly 4 is pressed down, it drives the liquid inside the cylinder 40 to flow. The flow of this liquid is transmitted to the telescopic assembly 3 through the pipeline, thereby controlling the telescopic movement of the telescopic assembly 3. Since the telescopic assembly 3 is installed in the fixing sleeve 12 on one side of the main board 10, and its driving end is connected to the through hole 13 in the middle of the main board 10, when the hydraulic assembly 4 drives the liquid to flow, the driving end of the telescopic assembly 3 will extend or retract from the through hole 13 accordingly.
[0031] Since the top plate 2 is fixedly connected to the driving end of the telescopic assembly 3, when the driving end of the telescopic assembly 3 is extended, the top plate 2 will also move until the other end of the top plate 2 (i.e. the side facing the subway) contacts the subway car. At this time, the hydraulic assembly 4 is operated continuously to make the driving end of the telescopic assembly 3 continue to extend, thereby pushing the top plate 2 to move and rescue the passenger's foot from the gap.
[0032] In addition, the hydraulic assembly 4 in this embodiment is connected to the telescopic assembly 3 through a pipeline. Therefore, during the rescue process, the hydraulic assembly 4 can be flexibly placed as needed and will not be affected by the placement position of the fixed bracket 1.
[0033] In some optional embodiments, a card slot 100 is provided on the inner side of the support plate 11 , and the card slot 100 is tightly engaged with two sides of the mainboard 10 to ensure the stability of the fixing bracket 1 .
[0034] In some optional implementations, a handle 14 is provided above the main board 10 to facilitate adjustment of the position of the device.
[0035] In some optional implementations, the length of the card slot 100 is slightly smaller than the height of the support plate 11. After the support plate 11 and the main board 10 are snapped together, the main board 10 will be lifted up by the support plate 11 off the ground, and only the support plates 11 on both sides are in contact with the ground. This avoids the shaking of the device due to the support plate 11 not being completely flush with the bottom surface of the main board 10 after mating, thereby improving the stability of the mating.
[0036] In some optional implementations, a 90° snap-in 110 is further provided on the outer side of the support plate 11 for snapping and fixing with the edge of the platform to enhance the stability of the entire device.
[0037] In some optional embodiments, a side groove 121 is provided on one side of the fixing sleeve 12 , and the pipe opening of the telescopic assembly 3 faces the side groove 121 for pipeline connection.
[0038] In some optional embodiments, the other end of the top plate 2 extends to below the main plate 10, and a soft pad 20 is provided on the side facing the subway for pressing against the top plate 2 under the subway car.
[0039] In some optional embodiments, the top plate 2 is designed to be "pear" shaped, with the narrow side connected to the telescopic component 3, the wide end extending to below the main board 10, and a pad 20 being provided. The "pear" shaped top plate 2 makes the overall structure more compact.
[0040] In some optional embodiments, an opening 120 is provided on a side of the fixing sleeve 12 facing away from the main board 10 , and the telescopic assembly 3 enters the fixing sleeve 12 through the opening 120 . A bottom cover 15 is provided at the opening 120 for sealing and fixing.
[0041] In some optional embodiments, a side groove 121 is provided on one side of the fixing sleeve 12 , and the pipe opening of the telescopic assembly 3 faces the side groove 121 for pipeline connection.
[0042] In some optional embodiments, the hydraulic assembly 4 includes a cylinder 40 and a pressure rod 41. The cylinder 40 is stably placed on the ground through supports on both sides to ensure stability during operation. The pressure rod 41 is drivingly connected to the cylinder 40, and by operating the pressure rod 41, the telescopic assembly 3 can be driven to perform telescopic movement.
[0043] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
