Description

Technical Field

[0001] This invention belongs to the field of transportation equipment technology, specifically a transportation lifting device based on the narrow space of a subway station building. Background Technology

[0002] A subway is a type of urban rail transit system, referring to a high-speed, high-capacity rail transit system built in cities that uses electric traction.

[0003] However, in the existing technology, due to the small space and winding passages in areas such as equipment rooms and corridors of subway stations, traditional handling equipment cannot enter because of its large size and insufficient turning radius. This makes it difficult to transport large electromechanical equipment and heavy materials. Moreover, when installing them, it is often necessary to build an additional platform or use multiple jacks for lifting and adjustment, which results in low efficiency and significant safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a transport and lifting device for the narrow space of a subway station, which can move and transport heavy materials and equipment in a confined space, thereby improving the efficiency of actual construction.

[0005] The technical solution adopted in this invention is as follows: A transport lifting device based on the narrow space of a subway station building, comprising: a moving mechanism for providing a transport lifting foundation; and An adjustment mechanism is used to cooperate with the moving mechanism to improve the lifting effect, and the adjustment mechanism is set on the moving mechanism.

[0006] The moving mechanism includes a vehicle body, four Mecanum wheels, and a lifting component. The four Mecanum wheels are respectively located on both sides of the vehicle body, and the lifting component is located on the vehicle body.

[0007] The lifting component includes two sliding rods, two first support rods, two second support rods, and a carrier plate. The two sliding rods are fixedly connected between the inner walls of opposite sides of the vehicle body. Each sliding rod has a movable seat slidably fitted on its outer surface. The two first support rods are rotatably connected to the outer surface of the corresponding movable seat on one side. The carrier plate is rotatably connected between the top ends of the two first support rods. The two second support rods are rotatably connected to the inner wall of one side of the vehicle body. The outer surface of one side of each second support rod is rotatably connected to the outer surface of the corresponding first support rod on one side.

[0008] The carrier plate has two placement slots on its top and two guide strips fixedly connected to its bottom.

[0009] Each of the second support rods is rotatably connected to a support wheel at its top, and the top of each support wheel is in contact with the bottom of the carrier plate.

[0010] Among them, a support threaded rod is rotatably connected between the inner surfaces of the two sides of the vehicle body, and a support seat is threadedly connected to the outer surface of the support threaded rod. The two ends of the support seat slide through the corresponding moving seats respectively. A linkage gear is sleeved on the outer surface of the support threaded rod. Four first hydraulic cylinders are fixedly connected to the outer surface of the vehicle body. The four first hydraulic cylinders are divided into two groups. A stop is fixedly connected between the output ends of the two first hydraulic cylinders in each group. Two load wheels are rotatably connected to the bottom of each stop.

[0011] A support motor is fixedly connected to the inner wall of one side of the vehicle body, and a drive gear is sleeved on the output end of the support motor. The drive gear meshes with the connecting gear.

[0012] The adjustment mechanism consists of two sets, each set including a mounting frame, a guide frame, a sliding frame, a second hydraulic cylinder, and a top plate. The mounting frame is fixedly connected to the bottom of the carrier plate, and the interior of the mounting frame is connected to the interior of the corresponding placement slot. The guide frame is fixedly connected to the inner wall of one side of the mounting frame. The sliding frame is slidably sleeved on the outer surface of the guide frame. The second hydraulic cylinder is fixedly connected to the outer surface of one side of the sliding frame. The top plate is slidably inserted into the interior of the corresponding placement slot.

[0013] Each of the second hydraulic cylinders has a connecting block fixedly connected to its output end. Each of the top plates has four limiting rods fixedly connected to its bottom. The bottom end of each limiting rod slides through the top of the carrier plate. Each limiting rod has an extension rod threadedly connected to its bottom end. Each of the mounting frames has a movable threaded rod rotatably connected to its inner wall on one side. Each movable threaded rod has a movable frame threadedly connected to its outer surface. One end of each movable frame is rotatably connected to the bottom end of its corresponding sliding frame. Each movable threaded rod has a rotating gear sleeved on its outer surface. Each of the mounting frames has a movable motor fixedly connected to its inner wall on one side. Each movable motor has a movable gear sleeved at its output end. Each movable gear meshes with its corresponding rotating gear.

[0014] A method for using a transport lifting device in the narrow space of a subway station includes the following steps: S1. Material Lifting: By controlling the start of the support motor, the support motor, in conjunction with the drive gear and linkage gear, drives the support threaded rod to rotate. This rotating threaded rod allows the support seat to adjust its position, which in turn allows the support seat to move synchronously with the moving seat, moving one end of the first support rod. During this movement, the first support rod, under the position constraint of the second support rod, supports and adjusts the height of the carrier plate. When the support seat approaches the support motor, the carrier plate gradually lowers to its lowest point, facilitating the transfer of heavy materials to the top of the carrier plate. Then, by reversing the operation of the support motor, the carrier plate lifts the heavy materials to the required height. When the top of the carrier plate carries heavy materials of different heights, the lower-height heavy materials can be placed on the top of the plate. Then, by controlling the start of the moving motor, the moving motor, together with the moving gear and the rotating gear, drives the moving threaded rod to rotate. The rotating moving threaded rod then moves the moving frame closer to the moving motor. During this process, the moving frame, under the position restriction of the guide frame, gradually moves and adjusts the slide frame to a vertical state. Then, the second hydraulic cylinder can follow the slide frame to maintain a vertical state. By controlling the start of the second hydraulic cylinder, under the position restriction of the limit rod and the extension rod, the second hydraulic cylinder can lift the top plate carrying the lower-height heavy materials to the required height. This allows the equipment to conveniently adjust the height of the heavy materials to be moved according to actual usage needs. S2. Space Adaptability: Supported by the Mecanum wheels, the vehicle body can move omnidirectionally in confined spaces, improving the equipment's flexibility in such environments. Furthermore, when carrying heavy materials, the first hydraulic cylinder is activated by controlling the start of the first cylinder, allowing it to work in conjunction with the support frame to ensure the load-bearing wheels are in contact with the ground. This, in turn, assists the Mecanum wheels in providing additional support to the vehicle body, ensuring the Mecanum wheels can efficiently perform their intended functions.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, during use, by controlling the start of the support motor, the support motor, in conjunction with the drive gear and the connecting gear, can drive the support threaded rod to rotate. The rotating support threaded rod can then adjust the position of the support seat by moving it, thereby enabling the support seat to move synchronously with the moving seat, causing one end of the first support rod to move. During this positional movement of the first support rod along with the moving seat, the first support rod, under the positional constraint of the second support rod, can support and adjust the height of the carrier plate. When the support seat approaches the support motor, the carrier plate will gradually descend to its lowest point, facilitating the transfer of heavy materials to the top of the carrier plate. Then, by reversing the operation of the support motor, the carrier plate will lift the heavy materials to the required height. Simultaneously, when the top of the carrier plate is not fully loaded... When handling heavy materials of the same height, the lighter heavy materials can be placed on top of the top plate. Then, by controlling and starting the moving motor, the moving motor, together with the moving gear and the rotating gear, drives the moving threaded rod to rotate. The rotating moving threaded rod then moves the moving frame gradually closer to the moving motor. During this process, the moving frame, under the position restriction of the guide frame, gradually moves and adjusts the sliding frame to a vertical state. This allows the second hydraulic cylinder to follow the sliding frame and maintain a vertical state. Then, by controlling and starting the second hydraulic cylinder, under the position restriction of the limit rod and the extension rod, the top plate carrying the lighter heavy materials is lifted to the required height. This allows the equipment to easily adjust the height of the heavy materials to be moved according to actual usage needs, thus enabling the equipment to efficiently perform its intended functions.

[0016] (2) In this invention, when in use, the vehicle body can be easily moved in all directions in a narrow space under the support of the Mecanum wheel, which improves the sensitivity of the equipment in a narrow space. At the same time, when carrying heavy materials, the first hydraulic cylinder is activated by controlling the start of the first hydraulic cylinder, so that the first hydraulic cylinder can cooperate with the support frame to support the load wheel to fit against the bottom surface. Then, under the support of the load wheel, the Mecanum wheel can assist the vehicle body to provide additional support, ensuring that the Mecanum wheel can efficiently perform its intended function, and enabling the equipment to efficiently perform its intended function.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] For examples, please refer to [link / reference]. Figures 1-3 A transport lifting device based on the narrow space of a subway station building, consisting of a moving mechanism 1 and an adjusting mechanism 2.

[0021] The details are as follows: Please see Figure 4 and Figure 5The moving mechanism 1 provides a transport lifting foundation. The moving mechanism 1 includes a vehicle body 101, four Mecanum wheels 102, and a lifting component. The four Mecanum wheels 102 are respectively located on both sides of the vehicle body 101. The lifting component is mounted on the vehicle body 101 and includes two sliding rods 105, two first support rods 107, two second support rods 108, and a carrier plate 110. The two sliding rods 105 are fixedly connected between the inner walls of opposite sides of the vehicle body 101. A movable seat 106 is slidably fitted onto the outer surface of each sliding rod 105. The two first support rods 107 are rotatably connected to the outer surface of one side of the corresponding movable seat 106. The carrier plate 110 is rotatably connected between the top ends of the two first support rods 107. The two second support rods 108 are rotatably connected to the vehicle body 101. On one side of the inner wall of body 101, the outer surface of one side of each second support rod 108 and the outer surface of the corresponding first support rod 107 are rotatably connected. Two placement slots are provided on the top of the carrier plate 110, and two guide strips 111 are fixedly connected to the bottom of the carrier plate 110. A support wheel 109 is rotatably connected to the top of each second support rod 108, and the top of each support wheel 109 is in contact with the bottom of the carrier plate 110. Support threaded rods 112 are rotatably connected between the two sides of the inner wall of the vehicle body 101. Support seats 113 are threadedly connected to the outer surface of the support threaded rods 112, and the two ends of the support seats 113 slide through the corresponding moving seats 106. A connecting gear 115 is sleeved on the outer surface of the support threaded rods 112. Four first hydraulic cylinders 10 are fixedly connected to the outer surface of the vehicle body 101. 3. The four first hydraulic cylinders 103 are divided into two groups. Each group has a fixed support frame between the output ends of the two first hydraulic cylinders 103. Each support frame has two rotatably connected wheels 104 at its bottom. A support motor 114 is fixedly connected to the inner wall of one side of the vehicle body 101. A drive gear is sleeved on the output end of the support motor 114. The drive gear and the connecting gear 115 mesh. By controlling the start of the support motor 114, the support motor 114, in conjunction with the drive gear and the connecting gear 115, can drive the support threaded rod 112 to rotate. This allows the rotating support threaded rod 112 to adjust the position of the support seat 113 by moving it. Consequently, the support seat 113, in conjunction with the movable seat 106, can synchronously drive one end of the first support rod 107 to move, thus enabling the first support rod 107 to move. As one end of the support rod 107 moves with the movable seat 106, and simultaneously, under the positional constraint of the second support rod 108, the first support rod 107, in conjunction with the second support rod 108, can support and adjust the height of the carrier plate 110. When the support seat 113 approaches the support motor 114, the carrier plate 110 will gradually descend to its lowest point, facilitating the transfer of heavy materials to the top of the carrier plate 110. Then, by reversing the operation of the support motor 114, the carrier plate 110 lifts the heavy materials to the required height. Supported by the Mecanum wheels 102, the vehicle body 101 can easily move omnidirectionally in confined spaces, improving the equipment's flexibility in such environments. Simultaneously, when carrying heavy materials, the first hydraulic cylinder 103 is activated by control.This allows the first hydraulic cylinder 103 to cooperate with the support frame to support the carrier wheel 104 in contact with the bottom surface. Under the support of the carrier wheel 104, it assists the Mecanum wheel 102 in providing additional support to the vehicle body 101, ensuring that the Mecanum wheel 102 can efficiently perform its intended function, thus enabling the equipment to perform its intended function efficiently. Please see Figure 6 The adjusting mechanism 2 is used to cooperate with the moving mechanism 1 to improve the lifting effect. The adjusting mechanism 2 is set on the moving mechanism 1. There are two sets of adjusting mechanisms 2. Each set of adjusting mechanisms 2 includes a mounting frame 201, a guide frame 202, a sliding frame 203, a second hydraulic cylinder 204, and a top plate 210. The mounting frame 201 is fixedly connected to the bottom of the carrier plate 110, and the interior of the mounting frame 201 is connected to the interior of the corresponding placement slot. The guide frame 202 is fixedly connected to the inner wall of one side of the mounting frame 201. The sliding frame 203 is slidably sleeved on the outer surface of the guide frame 202. The second hydraulic cylinder 204 is fixedly connected to the outer surface of one side of the sliding frame 203. The top plate 210 is slidably inserted into the corresponding placement slot. A connecting block 205 is fixedly connected to the output end of each second hydraulic cylinder 204. Four limiting rods 211 are fixedly connected to the bottom of each top plate 210. The bottom end of each limiting rod 211 slides through the top of the carrier plate 110. An extension rod 212 is threadedly connected to the bottom end of each limiting rod 211. A movable threaded rod 207 is rotatably connected to the inner wall of one side of each mounting frame 201. A movable frame 206 is threadedly connected to the outer surface of each movable threaded rod 207. One end of each movable frame 206 is rotatably connected to the bottom end of the corresponding sliding frame 203. A rotating gear 208 is fitted onto the outer surface of the movable threaded rod 207. A movable motor 209 is fixedly connected to the inner wall of one side of each mounting frame 201. A movable gear is fitted onto the output end of each movable motor 209. Each movable gear meshes with the corresponding rotating gear 208. When the top of the carrier plate 110 carries heavy materials of different heights, the lower-height heavy materials can be placed on the top of the top plate 210. Then, by controlling the start of the movable motor 209, the movable motor 209 can work with the movable gear and the rotating gear 208 to drive the movable threaded rod 207 to rotate, thereby causing the rotating movable threaded rod to rotate. 207 allows the movable frame 206 to gradually approach the movable motor 209. During this process, the movable frame 206, under the positional constraint of the guide frame 202, gradually moves and adjusts the sliding frame 203 to a vertical state. This allows the second hydraulic cylinder 204 to follow the sliding frame 203 and remain vertical. Then, by controlling the start of the second hydraulic cylinder 204, the second hydraulic cylinder 204, under the positional constraint of the limit rod 211 and the extension rod 212, lifts the top plate 210, which carries heavy materials with a low height, to the required height. This allows the equipment to conveniently adjust the height of the heavy materials to be moved according to actual usage needs.

[0022] The following provides a detailed description of the usage method of a transport lifting device based on the narrow space of a subway station, according to an embodiment of the present invention. The usage method includes the following steps: Step 1, Material Lifting: By controlling the start of the support motor 114, the support motor 114, in conjunction with the drive gear and the connecting gear 115, drives the support threaded rod 112 to rotate. The rotating support threaded rod 112 then moves to adjust the position of the support base 113. This allows the support base 113 to move synchronously with the movable seat 106, moving one end of the first support rod 107. During this movement, the first support rod 107, under the position constraint of the second support rod 108, supports and adjusts the height of the carrier plate 110. When the support base 113 approaches the support motor 114, the carrier plate 110 gradually lowers to its lowest point, facilitating the transfer of heavy materials to the top of the carrier plate 110. Then, by reversing the operation of the support motor 114, the carrier plate 110 is lifted to the required height, carrying the heavy materials. When the equipment is carrying heavy materials of different heights, the lower-height heavy materials can be placed on top of the top plate 210. Then, by controlling the start of the moving motor 209, the moving motor 209 can work with the moving gear and the rotating gear 208 to drive the moving threaded rod 207 to rotate. The rotating moving threaded rod 207 can then move the moving frame 206 to gradually approach the moving motor 209. During this process, the moving frame 206 can gradually move and adjust the sliding frame 203 to a vertical state under the position restriction of the guide frame 202. Then, the second hydraulic cylinder 204 can follow the sliding frame 203 to maintain a vertical state. By controlling the start of the second hydraulic cylinder 204, the second hydraulic cylinder 204 can lift the top plate 210 carrying the lower-height heavy materials to the required height under the position restriction of the limit rod 211 and the extension rod 212. This allows the equipment to conveniently adjust the height of the heavy materials according to actual usage needs, thereby enabling the equipment to efficiently perform its intended functions. Step 2, Space Adaptation: Supported by the Mecanum wheel 102, the vehicle body 101 can move omnidirectionally in confined spaces, improving the equipment's flexibility in such spaces. Simultaneously, when carrying heavy materials, the first hydraulic cylinder 103 is activated, allowing it to work in conjunction with the support frame to ensure the carrier wheel 104 is in contact with the bottom surface. The carrier wheel 104 then assists the Mecanum wheel 102 in providing additional support to the vehicle body 101, ensuring the Mecanum wheel 102 can efficiently perform its intended functions, thus enabling the equipment to perform its intended functions efficiently.
