TECHNICAL FIELD
[0001] The utility model relates to rescue equipment technical field, concretely relates to a subway platform rescue dilator. BACKGROUND
[0002] The subway platform rescue dilator is a tool specially used in the subway platform emergency rescue scene, and is mainly used for quickly expanding the gap or space when passengers are trapped (such as being clamped between the train door and the platform door, the limbs are stuck, etc.), and implementing the safe rescue equipment.
[0003] The traditional hydraulic dilator is bulky (usually length > 50 cm, weight > 10 kg), and it is difficult to operate flexibly in the narrow platform gap, and the smaller dilator is very limited in the position that can be used, and in some earlier built subways, the gap between the train and the platform is large, but the platform itself is small, the large dilator cannot be placed in place, and the small dilator cannot play the effect of expansion, which will affect the rescue speed.
[0004] Therefore, how to provide a subway platform rescue dilator to solve the defects existing in the structure of the existing hydraulic dilator is a technical problem to be solved by the person skilled in the art. UTILITY MODEL CONTENT
[0005] Therefore, the utility model provides a subway platform rescue dilator to solve the problem of low rescue efficiency caused by the fact that the dilator cannot adapt to all use scenarios in the prior art.
[0006] In order to achieve the above purpose, the utility model provides the following technical scheme:
[0007] The utility model discloses a subway platform rescue dilator, which comprises:
[0008] The first gasket is arranged in pairs, and a hydraulic assembly is installed between the two first gaskets.
[0009] The lifting handle is installed at one end on the front and rear sides of the hydraulic assembly, and the other end of the lifting handle is arranged above the hydraulic assembly.
[0010] A plurality of reset springs are installed between the two first gaskets, and the reset springs are arranged on the front and rear sides of the hydraulic assembly.
[0011] The hinge is installed at the top of the first gasket, and the other end of the hinge is connected with a second gasket, and the first gasket and the second gasket are arranged perpendicularly.
[0012] In a possible implementation manner, the second gasket comprises:
[0013] The plate body, one end surface is connected with the hinge, the other end of the plate body is provided with a slope;
[0014] A plurality of mounting holes are arranged on the top of the plate body.
[0015] A limiting plate is installed on the top surface of the plate body, and the limiting plate is arranged above the mounting hole.
[0016] In a possible implementation, the hydraulic assembly comprises:
[0017] A pair of limiting blocks are arranged and installed between the two first gaskets, and the limiting blocks are arranged inside the return spring;
[0018] A limiting groove is arranged on the inner surface of the limiting block;
[0019] A hydraulic cylinder is installed on the surface of the first gasket at both ends, and the hydraulic cylinder is clamped between the two limiting grooves at both ends;
[0020] An oil inlet interface is installed on the top of the hydraulic cylinder, and an oil inlet pipeline is connected to the top of the oil inlet interface.
[0021] In a possible implementation, the hinge is internally damped.
[0022] In a possible implementation, the pull handle comprises:
[0023] A pair of connecting plates are arranged and installed on the front and rear sides of the hydraulic assembly by screwing;
[0024] A pull rod is welded on the top of the two connecting plates.
[0025] In a possible implementation, a plurality of round holes are arranged on the first gasket, a round rod is arranged in the round hole, the end of the return spring is hung on the round rod, a rectangular groove is arranged on the outer surface of the top of the first gasket, one end of the hinge is installed in the rectangular groove, a connecting hole is arranged in the first gasket and the rectangular groove, and the connecting hole is arranged inside the round hole.

[0028] This invention utilizes a hinge to drive the second gasket to flip. When the second gasket is assembled, the resulting gasket is wider, allowing the expander to fit into platforms with wider gaps between the platform and the train. Because of the increased width, the overall length of the expander increases after the hydraulic components push it in, thus filling and widening the gap. Furthermore, the thick rubber gasket has strong resistance to deformation, preventing it from failing to expand due to deformation. When the first and second gaskets are set perpendicularly, the right-angle structure allows the expander to better fit into the gap. Using only the first gasket as a spacer is designed for narrower gaps, allowing the expander to be inserted and achieve the expansion effect. This significantly improves the expander's applicability and increases rescue and construction efficiency. Attached Figure Description

DETAILED DESCRIPTION
[0038] The embodiments of the present application will be described in detail by the specific embodiments, and the person skilled in the art can easily understand other advantages and effects of the present application from the disclosed content of the specification. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the present application.
[0039] Please refer to Figures 1-6 , a subway platform rescue expander disclosed by the present application will be described, and the present application has six parts, such as Figure 1 , including a pull handle 1, a hydraulic assembly 2, a reset spring 3, a first gasket 4, a second gasket 5 and a hinge 6, the first gasket 4 is arranged in pairs, the hydraulic assembly 2 is installed between the two first gaskets 4, one end of the pull handle 1 is installed on the front and rear sides of the hydraulic assembly 2, the other end of the pull handle 1 is arranged above the hydraulic assembly 2, a plurality of reset springs 3 are installed between the two first gaskets 4, the reset springs 3 are arranged on the front and rear sides of the hydraulic assembly 2, the hinge 6 is installed on the top of the first gasket 4, the other end of the hinge 6 is connected with the second gasket 5, and the first gasket 4 and the second gasket 5 are arranged perpendicularly.
[0040] The present application has two use modes when in use, one is for the case that the gap between the train and the platform is wide, and the subway door is thick, at this time, the second gasket 5 is turned over by the hinge 6, at this time, the bottom surface of the second gasket 5 is attached to the outer surface of the first gasket 4, at this time, the first gasket 4 and the second gasket 5 will form a thick gasket, at this time, the limiting plates 51 on the two second gaskets 5 are respectively abutted on the upper surface of the platform and the floor surface of the train, then the oil inlet pipe is connected by the oil inlet interface 21, then the oil pump is connected by the oil inlet pipe, the oil pump will push the hydraulic oil into the hydraulic cylinder 23, the hydraulic cylinder 23 will push Figure 1The first gasket 4 on the left side is displaced, and the first gasket 4 and the second gasket 5 are pressed to deform the train floor and the door body in the process of movement. When the train floor and the door body are deformed, the gap between the train and the platform gradually increases, thereby achieving the gap expansion effect and performing rescue. The thickness generated by the combination of the first gasket 4 and the second gasket 5 and the pushing amount generated by the hydraulic assembly 2 itself are combined, so that the expander can be used in a position where the gap between the train and the platform is relatively wide. In addition, the gasket formed by the first gasket 4 and the second gasket 5 is relatively thick, so that the gasket has good anti-deformation ability and impact force. In the case of a train with a relatively thick door body, the gasket can generate a relatively large impact force when impacting the train to deform, and can effectively prevent the gasket from deforming, thereby improving the rescue efficiency. The second use case is for the case where the gap between the train and the platform is relatively small. At this time, the first gasket 4 and the second gasket 5 form a 90° perpendicular angle through the hinge 6. The angle is used to quickly clamp the expander in the gap. At this time, the bottom surface of the second gasket 5 is against the surface of the platform and the train floor. After the expander is installed, the left first gasket 4 is driven to displace by the hydraulic cylinder 23, so that the left first gasket 4 is close to and presses the train floor and the door body to deform, thereby increasing the gap between the train and the platform to achieve the rescue effect. Through the above two ways, the expander can be used in a gap with a width of 80mm-120mm. In the second case, the right angle between the first gasket 4 and the second gasket 5 is used to quickly clamp the expander in the gap. In the first case, the clamping mode of the expander is to use the right angle between the limiting plate 51 and the plate body 52 to quickly place the expander in the gap.
[0041] In a specific embodiment, Figure 2 The second gasket 5 includes a limiting plate 51, a plate body 52, a slope 53, and a mounting hole 54. The plate body 52 is connected to the hinge 6 at one end surface. The slope 53 is arranged above the other end of the plate body 52. The mounting hole 54 is arranged on the top of the plate body 52. The limiting plate 51 is arranged on the top surface of the plate body 52 above the mounting hole 54. The limiting plate 51 and the plate body 52 can quickly clamp the expander in the gap between the platform and the train, thereby achieving quick rescue. The mounting hole 54 can change the installation position of the limiting plate 51, thereby achieving different clamping depths of the expander for different trains and platforms, thereby generating different pushing forces of the hydraulic assembly 2, and achieving different deformation degrees of the train to adapt to more application scenarios. The slope 53 can guide the quick installation of the expander and enable the expander to be quickly installed in place.
[0042] In a specific embodiment, Figure 3The hydraulic assembly 2 comprises an oil inlet interface 21, a limiting groove 22, a hydraulic cylinder 23 and limiting blocks 24. The limiting blocks 24 are arranged in pairs and are installed between the two first gaskets 4. The limiting blocks 24 are arranged inside the return springs 3. The limiting groove 22 is arranged on the inner surface of the limiting blocks 24. The hydraulic cylinder 23 is installed on the surface of the first gasket 4 at both ends. The hydraulic cylinder 23 is clamped between the two limiting grooves 22 at both ends. The oil inlet interface 21 is installed on the top of the hydraulic cylinder 23. The oil inlet pipeline is connected to the top of the oil inlet interface 21. The oil inlet pipeline is connected to the oil inlet interface 21. Then, the hydraulic cylinder 23 is supplied with oil. The limiting blocks 24 are arranged to form the limiting groove 22. The hydraulic cylinder 23 is limited by the two limiting grooves 22 to prevent displacement during reuse.
[0043] In a specific embodiment, the hinge 6 is internally damped. The damping structure can prevent sudden closure, which can cause the first gasket 4 and the second gasket 5 to be clamped to the worker's hand. At the same time, the damping structure can reduce the impact force when the first gasket 4 and the second gasket 5 are attached, increase the service life of the entire expander, and use the damping structure. After the second gasket 5 is actively turned over, the second gasket 5 will not be easily passively turned over.
[0044] In a specific embodiment, as shown in Figure 4 The pull handle 1 comprises connecting plates 11 and a pull rod 12. The connecting plates 11 are arranged in pairs and are screw-connected and installed at the front and rear sides of the hydraulic assembly 2. The pull rod 12 is welded to the top of the two connecting plates 11. The pull rod 12 is used for workers to better grasp the entire expander, so as to realize the portable movement and use of the expander.
[0045] In a specific embodiment, as shown in Figure 5 A plurality of round holes 42 are formed in the first gasket 4. Round rods 43 are arranged in the round holes 42. The end of the return spring 3 is hung on the round rod 43. A rectangular groove 44 is formed in the top outer surface of the first gasket 4. One end of the hinge 6 is installed in the rectangular groove 44. Connection holes 41 are formed in the first gasket 4 and the rectangular groove 44. The connection holes 41 are arranged inside the round holes 42. The round holes 42 are arranged to install the round rods 43. The round holes 42 of the two first gaskets 4 are connected to the return springs 3. After the hydraulic cylinder 23 is removed, the return springs 3 drive the two first gaskets 4 to move closer to each other, so that the expander returns to the initial state, facilitating the next use. The rectangular groove 44 is arranged to connect the hinge 6. The connection holes 41 are arranged to cooperate with the bolts to install the hinge 6 and the hydraulic assembly 2.
[0046] In a specific embodiment, as shown in Figure 6The bottom surface of the plate body 52 is provided with a mounting groove 521, one end of the hinge 6 is mounted in the mounting groove 521, and a plurality of threaded holes are arranged in the mounting groove 521. The mounting groove 521 is also arranged for connecting the hinge 6, and the threaded holes are matched with the hinge 6 fixed by bolts.
[0047] In a specific embodiment, the first gasket 4 and the second gasket 5 are made of aluminum. Aluminum has good impact resistance and strong oxidation resistance. After oxidation, the metal becomes more fragile, and if it becomes fragile, the dilator cannot expand.
[0048] Although the utility model has been described in detail above by general description and specific embodiments, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model belong to the scope of protection required by the utility model.
