Description

Technical Field

[0001] This invention relates to the field of high-speed rail carriage transportation technology, and more specifically, to a high-speed rail carriage transfer vehicle with a retractable rainproof canopy. Background Technology

[0002] High-speed rail carriage transfer cars are special transportation equipment designed specifically for the manufacturing, maintenance, storage, or cross-line transportation of high-speed rail carriages. Their core function is to safely and efficiently complete the short-distance or long-distance transfer of carriages.

[0003] A transport vehicle is disclosed in Chinese Patent Publication No. CN107472270A. The transport vehicle of this invention includes: a front end and a body. The body includes a cargo compartment, a platform, and a running gear. The cargo compartment is enclosed, with doors and windows, and seats inside. A support frame is connected to the bottom of the cargo compartment. Both the support frame and the platform are used to place tools and materials. The end face of the support frame at the rear of the cargo compartment is hinged to one end of the platform. The other end of the platform can rotate around the bottom of the end face of the support frame to be in a horizontal state or rotated to the upper end of the rear of the cargo compartment and connected to the rear of the cargo compartment. Multiple running gears are provided, respectively located at the bottom of the support frame and the front end, for running on rails. This design separates personnel, tools, and materials for partitioned placement, ensuring the safety of the workers.

[0004] In addition, to secure the transported goods, they are also connected and secured to the transport vehicle using straps or steel wires, thereby achieving the purpose of securing them.

[0005] To prevent excessive localized pressure from the wheels on the transport vehicle, which could lead to platform deformation or damage, sleepers are installed between the platform and the wheels to support the cargo box. During transport, the cargo box is affected by road bumps and its own weight, and the sleepers are in a fixed position. This frequent pressure from the wheels on the sleepers causes the indentation to increase, resulting in the cargo box swaying back and forth, affecting its stability and potentially creating safety hazards. Summary of the Invention

[0006] This invention provides a high-speed rail carriage transfer car with a retractable rainproof canopy. It utilizes the increased wheel sway to drive the support plate to move downward, and the traction plate pulls the inner retraction plate inward, so as to realize the lateral displacement of the inner extension plate to apply pressure to the wedge-shaped surface of the guide wedge plate, forcing the guide wedge plate to move longitudinally, thereby raising the height of the sleeper block to support the downward moving wheel, thus solving the problems mentioned in the background art above. To achieve the above objectives, the high-speed rail carriage transfer car with a retractable rainproof canopy includes a transport platform and a frame. Rainproof tarpaulins that can slide laterally are provided on both sides and the top surface of the frame. The transport platform is provided with a bottom plate and a slide rail laid on the bottom plate. The bottom plate has a stop mechanism. The sleepers that support the carriage are provided between the two sides of the stop mechanism. The stop mechanism can provide lateral constraint on the sleepers to limit the displacement of the sleepers. The sleeper block is provided with a support mechanism on its outside. The support mechanism includes a support part and a traction part. The support part is located above the sleeper block. When the carriage shakes, the support part uses the downward pressure of the carriage to apply pressure to the traction part. The traction part is located below the sleeper block and uses an inward retraction method to force the sleeper block to rise upward so that the height of the sleeper block matches the shaking wheel, thereby supporting the wheel.

[0007] Secondly, the support part includes a support plate with a hollowed-out area in the middle, which is used to accommodate the wheel, and L-shaped curved rods symmetrically arranged at the bottom of the support plate. The curved rods are used to intercept the sleeper blocks and limit their displacement.

[0008] The bottom of the bent rod is fixedly connected to a double-ear connecting plate, and the two sides of the double-ear connecting plate are rotatably connected to the traction part.

[0009] The traction unit includes an inner retractable plate located inside the stop plate and slidably connected to the slide rail, and a traction plate rotatably connected between the inner retractable plate and the double-ear connecting plate. Under normal conditions, the top of the inner retractable plate is bent inward and supports the pad plate. When the double-ear connecting plate moves downward, the traction plate pulls the inner retractable plate to retract inward and perform lateral displacement.

[0010] A guide wedge is fixedly installed at the bottom of the pad. The guide wedge has wedge-shaped surfaces on both sides and an arc shape in the middle. Several second balls are rotatably arranged on the wedge-shaped surfaces.

[0011] An inner extension plate is also fixedly installed inside the traction plate. The end of the inner extension plate has a first ball bearing. During the inward retraction phase of the traction plate, the first ball bearing moves along the wedge-shaped surface to force the guide wedge plate and the sleeper block to move upward synchronously, thereby enabling the sleeper block to support the wheel. Specifically, during the inward retraction of the inner plates on both sides, the inner extension plate moves closer to the guide wedge plate, the first ball moves along the wedge surface, and the arrangement of the second ball can reduce friction with the wedge surface. Moreover, the second ball is densely arranged, reducing the gap between adjacent second balls and making the upper and lower second balls stably connected. Thus, there is a component force that pushes the guide wedge plate upward to force the sleeper block to move upward to support the wheel and reduce the sway amplitude.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: By increasing the wheel sway amplitude, the support plate is driven to move downward, and the traction plate pulls the inner shrink plate inward. This causes the inner extension plate to move laterally and apply pressure to the wedge-shaped surface of the guide wedge plate, forcing the guide wedge plate to move longitudinally. This raises the height of the sleeper block to support the downward-moving wheel, reduce the sway amplitude of the carriage, and improve stability. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] During transportation, the carriages are affected by road bumps and their own weight. Since the sleepers are in a fixed position, the frequent pressure from the wheels on the sleepers causes the indentation to increase, resulting in the carriages swaying back and forth. This affects their stability and can easily lead to safety hazards. This invention provides a high-speed rail carriage transfer vehicle with a retractable rainproof canopy. See [link to relevant documentation]. Figures 1-3 As shown, the system includes a transport platform 100 and a frame 101. Rainproof tarpaulins 102 that can slide laterally are provided on both sides and the top surface of the frame 101. A retracting device (which is prior art and not shown in the figure) is provided at the front end of the frame 101 to retract and extend the rainproof tarpaulins 102. The rainproof tarpaulins 102 are used to block external rainwater to protect the internal transport compartment. When disassembling the compartment, the rainproof tarpaulins 102 are opened and the compartment can be lifted out by a crane.

[0017] When the carriage is hoisted into the transport platform 100, the transport platform 100 is equipped with a base plate 103 and a slide rail 104 laid on the base plate 103. The base plate 103 has a stop mechanism 110, and between the two stop mechanisms 110, sleepers 105 are arranged to support the carriage (rainproof tarpaulin 102 prevents rainwater from wetting the sleepers 105 and affecting their compressive strength). The stop mechanism 110 can provide lateral restraint to the sleepers 105 to limit their displacement and ensure the stability and reliability of the carriage support; specifically as follows: First of all, Figure 3 Based on and combined Figure 4 As shown, the specific structure of the stop mechanism 110 is illustrated. The stop mechanism 110 includes a stop plate 111 that is slidably disposed on the slide rail 104 and restricts the lateral movement of the sleeper block 105. A support area for accommodating the sleeper block 105 is formed between the two stop plates 111, so that when the wheel contacts the sleeper block 105, the wheel is restricted within the support area. That is, when the wheel moves down onto the sleeper block 105, the sleeper block 105 can only move within the support area under the restriction of the two stop plates 111, preventing the sleeper block 105 from shifting and affecting the stability of the wheel support.

[0018] On the other hand, before the wheel descends to contact the sleeper block 105, it is necessary to adjust the distance between the two side stop plates 111 to block the sleeper block 105. Therefore, a lead screw 112 and a support frame 113 threadedly connected to the lead screw 112 are provided on the outside of the stop plate 111. The lead screw 112 is coaxially connected to the rotating wheel. By rotating the rotating wheel, the lead screw 112 is driven to rotate synchronously, causing the two side stop plates 111 to move inward and fit against the side of the sleeper block 105, thereby achieving the purpose of limiting the lateral displacement of the sleeper block 105. In addition, the other end of the lead screw 112 is fitted with an outer cylinder 111a that is fixedly connected to the stop plate 111. The outer cylinder 111a is provided with a limiting spring 111b that elastically connects the outer cylinder 111a and the stop plate 111. The bottom of the support frame 113 is fixed on the base plate 103. So, when the wheel drives the sleeper block 105 to move laterally due to road bumps, that is, when the sleeper block 105 applies pressure to the stop plate 111 on one side, the limiting spring 111b on that side, together with the damper (not shown in the figure) installed inside it, can reduce the shaking of the carriage. At the same time, the limiting spring 111b on the opposite side pushes the stop plate 111 closer to the other stop plate 111 under the elastic action, so that the two stop plates 111 and the sleeper block 105 are always in contact to prevent displacement.

[0019] Furthermore, a support mechanism 120 is provided on the outside of the sleeper block 105. The support mechanism 120 includes a support part and a traction part. The support part is located above the sleeper block 105. When the car body sways, the support part uses the downward pressure of the car body to apply pressure to the traction part. The traction part is located below the sleeper block 105 and uses an inward retraction method to force the sleeper block 105 to rise upward so that the height of the sleeper block 105 matches the swaying wheel, thereby supporting the wheel and reducing the swaying of the car body.

[0020] The following is based on Figure 4 Based on and combined Figure 5 As shown, the support section is disclosed, including a support plate 121 with a hollowed-out area in the middle for accommodating the wheel, and L-shaped curved rods 122 symmetrically arranged at the bottom of the support plate 121. The curved rods 122 are used to intercept the sleeper block 105 and limit its displacement. Rubber pads 121a are provided on both sides of the support plate 121. Under normal conditions, the rubber pads 121a have a gap between them and the wheel axle to prevent the wheel from contacting the rubber pads 121a under slight shaking. When the shaking amplitude of the carriage increases, the rubber pads 121a can reduce the rigid contact and friction with the wheel axle. At this time, the wheel just lands on the sleeper block 105 and remains stable. A double-ear connecting plate 125 is fixedly connected to the bottom of the curved rod 122. The double-ear connecting plate 125 is rotatably connected to the traction unit on both sides. In addition, combined with Figure 7As shown, the traction unit includes an inner retractable plate 123 located inside the stop plate 111 and slidably connected to the slide rail 104, and a traction plate 124 rotatably connected between the inner retractable plate 123 and the double-ear connecting plate 125. Under normal conditions, the top of the inner retractable plate 123 is bent inward and forms support for the pad 106. When the double-ear connecting plate 125 moves down, the traction plate 124 pulls the inner retractable plate 123 to retract inward and perform lateral displacement. The specific working principle is as follows: In the initial stage (when the wheel falls onto the sleeper block 105), the heavy weight of the carriage forces an indentation to form on the sleeper block 105. At this time, the inner shrink plate 123 supports the weight above the bottom plate 103, and the inner shrink plate 123 is blocked by the two side stop plates 111 to limit the outward displacement of the inner shrink plate 123. Then, affected by the road surface, the carriage shakes more, which increases the depth of the indentation formed by the wheel on the sleeper block 105.

[0021] Therefore, when the wheel axle is moved down to Figure 7 In the indicated state, the wheel axial force applies downward pressure to drive the support plate 121 and the bent rod 122 to move downward synchronously. Similarly, the double-ear connecting plate 125 moves downward, pulling the two side traction plates 124 to rotate. According to the force decomposition, the lateral component of the traction force of the double-ear connecting plate 125 on the traction plate 124 forces the inner retraction plate 123 to retract and move inward, that is, the two side inner retraction plates 123 displace inward. At this time, combined with... Figure 6 As shown, a guide wedge plate 107 is fixedly provided at the bottom of the pad 106. The guide wedge plate 107 has wedge-shaped surfaces on both sides and an arc shape in the middle. Several second balls 107a are rotatably arranged on the wedge-shaped surface. On the other hand, an inner extension plate 123a is also fixedly provided on the inner side of the traction plate 124. The end of the inner extension plate 123a has a first ball 123b. During the inward retraction stage of the traction plate 124, the first ball 123b moves along the wedge-shaped surface to force the guide wedge plate 107 and the sleeper block 105 to move upward synchronously, so as to realize the support of the sleeper block 105 for the wheel.

[0022] That is, during the inward retraction of the inner plates 123 on both sides, the inner extension plate 123a moves closer to the guide wedge plate 107, the first ball 123b moves along the wedge surface, and the arrangement of the second ball 107a can reduce the friction with the wedge surface. Moreover, the second ball 107a is densely arranged, reducing the gap between adjacent second ball 107a, so that the upper and lower second ball 107a are stably connected. Thus, there is a component force that pushes the guide wedge plate 107 upward, so as to force the sleeper block 105 to move upward to support the wheel and reduce the sway amplitude.

[0023] In other words, by increasing the wheel sway amplitude, the support plate 121 is driven to move downward, and the traction plate 124 pulls the inner shrink plate 123 inward, so that the inner extension plate 123a is laterally displaced and puts pressure on the wedge surface of the guide wedge plate 107, forcing the guide wedge plate 107 to move longitudinally, thereby raising the height of the sleeper block 105 to support the downward moving wheel, reduce the sway amplitude of the carriage, and improve stability.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
