Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0055] See also Figure 1 to Figure 6 As shown, a thin trolley includes a base frame 104 and a rotating table 105 mounted on the base frame 104 for carrying a vehicle, the thickness of the base frame 104 corresponds to a first height interval H1, the gap between the base frame 104 and the rotating table 105 corresponds to a second height interval H2, the thickness of the rotating table 105 corresponds to a third height interval H3, the sum of all height intervals is 250 to 320 mm, wherein the second height interval H2 is 5 to 26 mm; the thin trolley also includes:

[0056] A walking system installed on the base frame 104, the walking system includes at least four walking wheels 113, at least two of the walking wheels 113 are equipped with independent walking motors 114, and in the height direction, all the walking wheels 113 and the walking motors 114 are in a first height range;

[0057] A driving mechanism 106 mounted on the base frame 104 is used to drive the rotating table 105 to rotate around a vertical axis;

[0058] A control cabinet 115 installed on one side of the base frame 104 in the horizontal direction, the control cabinet 115 is located in the first height range, and a control system for controlling the travel motor 114 and the drive mechanism 106 is provided in the control cabinet 115;

[0059] The cable routing mechanism 10 is mounted on the rotating platform 105, and the cable 102 reel in the cable routing mechanism 10 is above the second height interval H2;

[0060] The motion stabilizing device 20 acts between the base frame 104 and the rotating platform 105, and the motion stabilizing device 20 includes a support plate fixed on the rotating platform 105, and a supporting wheel installed on the base frame 104 and matched with the bottom surface of the support plate.

[0061] The base frame 104 provides bottom support for the thin trolley, and provides sufficient strength for the entire frame by selecting suitable profiles (of any type) and layout methods. The thickness of the base frame 104 corresponds to the first height range, and the first height range is not greater than 200mm; the skeleton of the turntable 105 is assembled with profiles (of any type), and the thickness of the turntable 105 corresponds to the second height range, and the first height range is not greater than 250mm.

[0062] In the present application, the thickness of the base frame 104 should be understood as the thickness of the frame of the base frame 104, the thickness of the turntable 105 should be understood as the thickness of the frame of the turntable 105, and the gap between the base frame 104 and the turntable 105 should be understood as the distance between the base frame 104 and the frame of the turntable 105. It should not be understood that all components on the base frame and the turntable have an impact on the thickness.

[0063] By controlling the height of the base frame 104, the height of the rotating table 105, and the gap between the base frame 104 and the rotating table 105 in the height direction, the overall height of the trolley is controlled below 320 mm, effectively solving the problem of the trolley being too high.

[0064] In order to control the height of the trolley, the travel motor 114, the control cabinet 115, the cable routing mechanism 10, the motion stabilizing device 20, and the driving mechanism 106 are all height-controlled.

[0065] The driving mechanism 106 is located in the middle of the base frame 104. The driving mechanism 106 is used to drive the rotation of the rotating platform 105 and connect the base frame 104 and the rotating platform 105. The driving mechanism 106 can be in various forms. For example, the driving mechanism 106 includes: a driving motor 108 installed on the base frame 104, a gear driven by the driving motor 108, and a gear ring installed on the rotating platform 105 and meshing with the gear. The driving motor 108 drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the rotating platform 105 to rotate. The driving mechanism 106 is basically located in the height interval of the base frame 104 and the rotating platform 105 (including the gap between the base frame 104 and the rotating platform 105) in terms of height, and does not occupy additional height space.

[0066] See also Figure 4As shown, the chassis 104 is a rectangular frame, and the running wheels 113 are divided into two groups, and the two groups of running wheels 113 are respectively arranged on both sides of the running direction of the chassis 104, and each group of running wheels 113 has two, and one of the running wheels 113 is equipped with an independent running motor 114. The heights of the two running motors 114 are both located within the first height range, providing power for the overall movement of the chassis 104.

[0067] See also Figure 4 As shown, support plates 110 are laid at both ends of the length direction of the base frame 104, and the side of the support plate 110 adjacent to the rotating platform 105 has an arc-shaped edge adapted to the outer edge of the rotating platform 105, and the upper surface of the support plate 110 is flush with the parking surface of the rotating platform 105. The connection between the support plate 110 and the parking surface of the rotating platform 105 improves safety.

[0068] The base frame 104 is provided with a rotation detection system 112 for detecting the rotation position of the rotating platform 105. The rotation detection system 112 includes a plurality of sensors mounted on the base frame 104 and a plurality of triggering members mounted on the rotating platform 105. The rotation position of the rotating platform 105 is determined by sensing signals from the sensors. The sensors may be in various forms, for example, photoelectric detectors.

[0069] End buffer mechanisms 111 are installed at the four corners of the chassis 104. The end buffer mechanisms 111 are located at the front and rear sides of the travel direction to protect the trolley in the event of an accident. Guide devices are installed on both sides of the length direction of the chassis 104. Specifically, the guide devices are guide wheels 109 with vertical axes. When the three-dimensional parking garage is running, the guide wheels 109 abut against the matching tracks to ensure the smooth operation of the trolley.

[0070] See also Figure 3 As shown, an operation alarm device 103 is also installed on the rotating platform 105. The operation alarm device 103 is respectively located at the four corners of the rotating platform 105, and emits an alarm sound when the equipment is running to serve as a warning.

[0071] A pedal 116 is also provided on the rotating platform 105 to improve the safety of the rotating platform 105. Guardrails 107 are installed on opposite sides of the rotating platform 105 to protect the construction workers.

[0072] The control cabinet 115 is located in the first height interval in the height direction to avoid interference with the rotating platform 105. The control system is used to control the movement of the entire trolley. The control system receives instructions from the stereo garage control system, controls the travel motor 114 to move the chassis 104, receives the rotation position information of the rotating platform 105 from the rotation detection system 112, and controls the driving mechanism 106 to drive the rotating platform 105 to rotate according to the rotation position information.

[0073] The cable routing mechanism is located inside the rotating platform 105 and can be flexibly arranged as required, such as Figures 7 to 12 As shown, the cable routing mechanism 10 can guide the cable to extend above the trolley parking surface 101 so that the cable 102 extends out from the cable outlet on the trolley parking surface 101 .

[0074] The cable routing mechanism 10 includes a cable drum 11, a plurality of guide wheels 12, a steering wheel 13 and a rope-pressing wheel 14 which are installed on a rotating platform 105 and rotate in sequence along the extension path of the cable 102; the cable drum 11 is located on one side of the rotating platform 105 in the horizontal direction; the extension path of the cable 102 defined by the plurality of guide wheels 12 starts from the outlet position of the cable drum 11, passes under the trolley parking surface 101 and extends to the entry position of the steering wheel 13; the steering wheel 13 is used to guide the cable 102 to extend toward the rope-pressing wheel 14, and the rope-pressing wheel 14 is used to guide the cable 102 to extend above the trolley parking surface 101.

[0075] It can be understood that the cable 102 coming out of the cable drum 11 is guided by the guide wheel 12 to the steering wheel 13. After the cable 102 changes direction through the steering wheel 13, the cable pressing wheel 14 guides the cable 102 to extend above the trolley parking surface 101. The cable drum 11 is located on one side of the rotating platform 105 in the horizontal direction, so that the height of the cable drum 11 can be prevented from affecting the height of the rotating platform 105, thereby reducing the height of the rotating platform 105.

[0076] After the cable 102 passes through the steering wheel 13, the cable 102 rotates about 90 degrees in the horizontal direction. Of course, in other embodiments, after the cable 102 passes through the steering wheel 13, the cable 102 rotates in the horizontal direction at an angle not limited to 90 degrees, and this angle depends on the installation position of the steering wheel 13 and the rope pressing wheel 14, which will not be elaborated here.

[0077] Furthermore, the angle between the axis of the steering wheel 13 and the vertical direction is 0 to 45 degrees, and the angle between the axis of the rope pressing wheel 14 and the horizontal direction is 0 to 45 degrees.

[0078] It is understandable that when the angle between the axis of the steering wheel 13 and the vertical direction is too large, the cable 102 and the steering wheel 13 will have too small an angle of contact, and the cable 102 and the steering wheel 13 will be separated. When the angle between the axis of the rope pressing wheel 14 and the horizontal direction is too small, the cable 102 and the steering wheel 13 will be separated. When the angle between the axis of the rope pressing wheel 14 and the horizontal direction is too large, when the cable passes through the rope pressing wheel 14 and extends above the trolley parking surface 101, the angle between the cable 102 and the rope pressing wheel 14 will also be too small, and the cable 102 and the rope pressing wheel 14 will be separated.

[0079] The outer periphery of the steering wheel 13 and the outer periphery of the rope pressing wheel 14 are both provided with an annular groove cooperating with the cable 102 . The provision of the annular groove can further prevent the cable from escaping from the steering wheel 13 or the rope pressing wheel 14 .

[0080] In this embodiment, the horizontal plane 220 mm below the trolley parking surface 101 is used as the reference plane, and all components in the cable routing mechanism 10 are located above the reference plane. To avoid excessive influence of the cable routing mechanism 10 on the height of the rotating platform 105, the height of the rotating platform 105 can be further reduced.

[0081] In another embodiment, if Figure 8 As shown, the axis of the cable drum 11 is arranged horizontally, and the outlet position of the cable drum 11 is located at the bottom side of the cable drum 11 in the vertical direction.

[0082] It can be understood that the cable drum 11 is mounted on the rotating platform 105 through the mounting seat 1110, the cable drum 11 is rotatably connected to the mounting seat 1110, and the mounting seat 1110 is fixedly mounted on the rotating platform 105 by welding or bolts. The axis of the cable drum 11 is arranged horizontally, which can reduce the height of the cable drum 11 in the vertical direction, thereby further reducing the height of the rotating platform 105.

[0083] In another embodiment, if Fig. 9 As shown, the angle between the axis of the steering wheel 13 and the vertical direction is 5 to 30 degrees, and the line entry position of the steering wheel 13 is higher than the line exit position of the steering wheel 13.

[0084] It is understandable that when the angle between the axis of the steering wheel 13 and the vertical direction is too small, when the line entry position of the steering wheel 13 and the line exit position of the guide wheel 12 are misaligned in the horizontal position, the cable 102 and the steering wheel 13 will have a too small wrap angle, and the cable 102 will easily separate from the annular groove on the steering wheel 13 during the movement of the cable 102. Similarly, when the angle between the axis of the steering wheel 13 and the vertical direction is too large, the cable 102 and the steering wheel 13 will also have a too small wrap angle, and the cable 102 will also separate from the annular groove on the steering wheel 13.

[0085] The steering wheel 13 is mounted on the rotating platform 105 via a wheel frame 131 . The steering wheel 13 is rotatably mounted on the wheel frame 131 . The wheel frame 131 is fixed to the rotating platform 105 by welding or bolts.

[0086] In one embodiment, the angle between the axis of the steering wheel 13 and the vertical direction is 15 degrees.

[0087] Furthermore, the outlet position of the deflection wheel 13 is at the same height as the inlet position of the rope pressing wheel 14. The cable 102 is horizontally arranged between the deflection wheel 13 and the rope pressing wheel 14 to increase the wrap angle between the cable 102 and the deflection wheel 13 and the rope pressing wheel 14 so that the cable 102 can reach the rope pressing wheel 14 smoothly from the deflection wheel 13.

[0088] In another embodiment, if Figure 8 and Fig.10 As shown, a line-receiving wheel 15 is further provided on one side of the horizontal radial direction of the rope-pressing wheel 14 , and a line outlet position of the rope-pressing wheel 14 is located between the rope-pressing wheel 14 and the line-receiving wheel 15 .

[0089] It is understandable that after the cable 102 passes through the rope pressing wheel 14, the running direction of the cable 102 after passing through the steering wheel 13 can be adjusted, and then the cable 102 is guided out of the trolley parking surface 101 by the wire wheel 15. The arrangement of the wire wheel 15 can guide the cable 102.

[0090] The rope pressing wheel 14 and / or the line wheel 15 are installed on the rotating table 105 through the mounting base 141. The rope pressing wheel 14 and / or the line wheel 15 can be fine-tuned in the horizontal and vertical directions (horizontally, the horizontal direction has mutually perpendicular horizontal and vertical directions) through the mounting base 141 to adapt to the adjustment of the assembly requirements of the rope pressing wheel 14 and / or the line wheel 15 during actual use, which will not be elaborated here.

[0091] In this embodiment, the angle between the axis of the rope pressing wheel 14 and the horizontal direction is 0 to 5 degrees, and the axes of the rope pressing wheel 14 and the line wheel 15 are parallel to each other.

[0092] In another embodiment, if Fig.11 and Fig.12 As shown, a wire groove 122 is provided on the periphery of each guide wheel 12 , and along the extension path of the cable 102 , the width of the wire groove 122 of an upstream guide wheel 12 is H1 , and the width of the wire groove 122 of a downstream guide wheel 12 is H2 , and H1 is greater than H2 .

[0093] It is understandable that, in the process of the cable 102 coming out of the cable reel 11, the outlet position of the cable reel 11 will change along its own axial direction to cause a change in the angle between the cable 102 and the entry position of the steering wheel. Therefore, the width of the wire groove 122 of the downstream guide wheel 12 is smaller than the width of the wire groove 122 of the upstream guide wheel 12, so as to guide the cable 102, so that the cable 102 can be smoothly introduced into the steering wheel 13, so that the cable 102 is within the receiving adaptation range of the entry position of the steering wheel 13.

[0094] Alternatively, along the extension path of the cable 102 , the width of the wire groove 122 of each guide wheel 12 gradually decreases.

[0095] Further, each guide wheel 12 is directly or indirectly mounted on the rotating platform 105. When each guide wheel 12 is indirectly mounted on, each guide wheel 12 is fixedly mounted on the rotating platform 105 through a connecting member 121.

[0096] In another embodiment, if Figure 7 As shown, at least one of the guide wheels 12 is located below the extension path of the cable 102 to support the cable 102, and the remaining guide wheels 12 are located above and / or below the extension path of the cable 102, respectively.

[0097] It can be understood that the arrangement of each guide wheel 12 can ensure that the cable 102 stably accesses the steering wheel 13. The cable 102 is supported by the guide wheel 12 to ensure the output height of the cable 102. The guide wheel 12 located below the extension path of the cable 102 is arranged at a corresponding height according to the actual requirements of the output height of the cable 102.

[0098] In this embodiment, there are three guide wheels 12, and two of the guide wheels 12 are located below the extension path of the cable 102 to support the cable 102. Of course, in other embodiments, the number of guide wheels 12 and the installation positions of the guide wheels 12 can be arranged according to the actual cable 102 outlet requirements, which will not be elaborated here.

[0099] In another embodiment, the rotating platform 105 is provided with a cable passing hole at a position interfering with the extension path of the cable 102 , and a cable protective member is installed at the edge of the cable passing hole.

[0100] It is understandable that the cable protection member is made of nylon (polyamide). In other embodiments, the cable protection member may also be made of materials such as rubber. When the cable 102 passes through the wire hole, the inner wall of the wire hole can also play a supporting role for the cable 102. The provision of the cable protection member can protect the cable 102 and prevent the side wall of the wire hole from cutting the cable 102, thereby shortening the service life of the cable 102.

[0101] Specifically, the cable protection member is provided with a through hole for the cable 102 to pass through, and the outer wall of the cable protection member is matched and fixed with the inner wall of the through hole. The inner diameter of the through hole is greater than the thickness of the cable, so that the cable can slide along the through hole.

[0102] In another embodiment, at least one of the deflection wheel 13 and the rope pressing wheel 14 is further provided with a rope pressing rod to prevent the cable 102 from jumping off.

[0103] It is understandable that the rope pressing rod is fixed to the rotating platform 105 by welding or bolts, and the arrangement of the rope pressing rod can prevent the cable 102 from accidentally jumping out of the steering wheel 13 or the rope pressing wheel 14 during operation. At the meshing position between the cable 102 and the steering wheel 13 or the rope pressing wheel 14, there is only a small gap between the rope pressing rod and the cable 102, and the gap is smaller than the thickness of the cable 102. This gap prevents the rope pressing rod from interfering with the rotation of the steering wheel 13 or the rope pressing wheel 14, and at the same time, it can also prevent the cable 102 from jumping out of the annular groove of the steering wheel 13 or the rope pressing wheel 14 in an accidental situation.

[0104] The motion stabilizing device 20 is located within the height range of the chassis, such as Figures 13 to 19 As shown, the motion stabilizing device 20 includes: an inner ring support plate 21 and an outer ring support plate 22 fixed to the bottom of the rotating table 105 and arranged around the axis of the rotating table 105, wherein the outer ring support plate 22 is composed of two sections arranged at intervals along the circumferential direction, and the bottom surfaces of the inner ring support plate 21 and the outer ring support plate 22 serve as working surfaces; an inner ring supporting wheel 23 and an outer ring supporting wheel 24 installed on the base frame 104 and arranged around the axis of the rotating table 105, the inner ring supporting wheel 23 supports the working surface of the inner ring support plate 21, and the outer ring supporting wheel 24 supports the working surface of the outer ring support plate 22.

[0105] It is understandable that when the rotating table 105 rotates, the rotating table 105 is deformed under load and force. When the outer ring support plate 22 of the rotating table 105 rotates to the position of the outer ring supporting wheel 24, the working surface of the outer ring support plate 22 contacts the outer peripheral edge of the outer ring supporting wheel 24, and the outer ring supporting wheel 24 is pressed and rolled under the outer ring support plate 22 to support the rotating table 105 to keep the rotating table 105 running smoothly; the working surface of the inner ring support plate 21 contacts the outer peripheral edge of the inner ring supporting wheel 23, and the inner ring supporting wheel 23 is pressed and rolled under the inner ring support plate 21 to support the rotating table 105, and the inner ring supporting wheel 23 keeps the rotating table 105 running smoothly.

[0106] Specifically, the inner ring support plate 21 and the outer ring support plate 22 are in the original gap space between the base frame 104 and the rotating table 105, and do not affect the overall height of the trolley 100, that is, the space for the inner ring support plate 21 and the inner ring supporting wheel 23 to interact with each other and the space for the outer ring support plate 22 and the outer ring supporting wheel 24 to interact with each other is the original gap space between the base frame 104 and the rotating table 105, and does not affect the height of the overall trolley 100. The outer ring supporting wheel 24 keeps the rotating table 105 stable when it is about to rotate into place and after it rotates into place.

[0107] The outer ring support plate 22 has a diameter D1, the inner ring support plate 21 has a diameter D2, and D1 is 1.6 to 3 times of D2, so that the inner ring support wheel 23 and the outer ring support wheel 24 can stably support the rotating platform 105, so that the rotating platform 105 can rotate smoothly.

[0108] In this embodiment, the diameter corresponding to the outer ring support plate 22 (with the center of the base frame 104 as the center of the circle) is 5100 mm, and the diameter corresponding to the inner ring support plate 21 (with the center of the base frame 104 as the center of the circle) is 2500 mm. Of course, in other embodiments, the diameter corresponding to the outer ring support plate 22 and the diameter corresponding to the inner ring support plate 21 can be adjusted according to actual needs, which will not be elaborated here.

[0109] In another embodiment, if Figure 13 to Figure 18 As shown, the rotating table 105 has relative length and width directions, the inner ring support plate 21 is annular and arranged in the middle of the length direction of the rotating table 105, and the two sections of the outer ring support plates 22 are respectively arranged at both ends of the length direction of the rotating table 105.

[0110] It is understandable that there are two outer ring support plates 22, which are welded or bolted to the left and right ends of the chassis 104 (depending on the attached Fig.13 The base frame 104 is arranged to determine the left and right ends of the base frame 104 ). The inner ring support plate 21 is arranged in an annular shape, and the inner ring support plate 21 is fixed to the base frame 104 by welding or bolts, and the center of the inner ring support plate 21 coincides with the center of the base frame 104 .

[0111] The working surface of the outer ring support plate 22 and the working surface of the inner ring support plate 21 are in the same plane, and the plane is perpendicular to the axis of the rotating table 105. The thickness of the outer ring support plate 22 and the inner ring support plate 21 is less than 10 mm, and is located in the gap between the base frame 104 and the rotating table 105, and does not affect the height of the entire trolley 100.

[0112] In another embodiment, if Figure 5 As shown, there are 8 to 12 inner ring supporting wheels 23 arranged in a ring shape on the base frame 104; there are two groups of outer ring supporting wheels 24 which are symmetrically arranged on both sides of the inner ring supporting wheels 23 in the radial direction.

[0113] It can be understood that the load is placed on the rotating table 105. When the rotating table 105 is deformed due to load and force, the working surface of the outer ring support plate 22 contacts the outer peripheral edge of the outer ring supporting wheel 24, and the working surface of the inner ring support plate 21 contacts the outer peripheral edge of the inner ring supporting wheel 23. The arrangement of the inner ring supporting wheel 23 and the outer ring supporting wheel 24 on the base frame 104 can make the deformation of the rotating table 105 uniform. At the same time, the inner ring supporting wheel 23 and the outer ring supporting wheel 24 are subjected to uniform force, avoiding uneven force on the inner ring supporting wheel 23 and the outer ring supporting wheel 24, which causes damage to the inner ring supporting wheel 23 and the outer ring supporting wheel 24.

[0114] Each group of outer ring supporting wheels 24 includes 4 to 8 wheels arranged at intervals along the circumferential direction.

[0115] In this embodiment, the number of each group of outer ring supporting wheels 24 is 4, and the number of outer ring supporting wheels 24 is 12. Of course, in other embodiments, the number and position of the outer ring supporting wheels 24 can be adjusted according to actual needs. Similarly, the number and position of the outer ring supporting wheels 24 can be adjusted according to actual needs, which will not be elaborated here.

[0116] In another embodiment, the outer peripheral edges of the inner ring supporting wheel 23 and the outer ring supporting wheel 24 that match the working surface are higher than the upper end surface of the base frame 104, and the height of the higher edges is no more than 16 mm.

[0117] It is understandable that the outer periphery of the inner ring supporting wheel 23 and the outer ring supporting wheel 24 that cooperate with the working surface is too high. In order to meet the assembly requirements, the gap between the base frame 104 and the rotating table 105 will be increased, thereby causing the height of the trolley 100 to increase, thereby increasing the manufacturing cost of the trolley 100.

[0118] In another embodiment, a part or all of the inner ring supporting wheels 23 and the outer ring supporting wheels 24 are installed on the base frame 104 through a height-adjustable wheel seat 26 .

[0119] It is understandable that the inner ring supporting wheel 23 and the outer ring supporting wheel 24 are both mounted on the base frame through the wheel seat 26, wherein a part or all of the wheel seats 26 are height-adjustable. The arrangement of the height-adjustable wheel seat 26 can ensure that the heights of the outer peripheries of the inner ring supporting wheel 23 and the outer ring supporting wheel 24 that match the working surface are the same. When the inner ring supporting wheel 23 and the outer ring supporting wheel 24 are assembled on the base frame 104, there will be an assembly error. By adjusting the wheel seats 26 on the inner ring supporting wheel 23 and the outer ring supporting wheel 24, the heights of the outer peripheries of the inner ring supporting wheel 23 and the outer ring supporting wheel 24 that match the working surface are changed to meet the assembly height of the inner ring supporting wheel 23 and the outer ring supporting wheel 24.

[0120] The height-adjustable wheel seat 26 includes a bracket, an adjusting screw and two adjusting nuts. The inner ring supporting wheel 23 and the outer ring supporting wheel 24 are rotatably mounted on the bracket. The bottom frame 104 is provided with a through hole for the adjusting screw to pass through. The adjusting screw has an external thread, and each adjusting nut has an internal thread that matches the external thread. One end of the adjusting rod is connected to the bracket, and the other end passes through the through hole. The two adjusting nuts are respectively threadedly connected to the adjusting screw and are respectively located on both sides of the bottom frame 104. By rotating the two adjusting nuts to change the position of the adjusting screw and the bottom frame 104, the corresponding inner ring supporting wheel 23 and the outer ring supporting wheel 24 can be adjusted to match the outer peripheral height of the working surface.

[0121] In another embodiment, if Fig.18 and Fig.19 As shown, the guide member 25 is fixedly connected to the end of each section of the outer ring support plate 22, and the guide member 25 is connected to the working surface of the corresponding section of the outer ring support plate 22 through a guiding inclined surface, and the guiding inclined surface gradually rises as it moves away from the outer ring support plate 22 along the circumferential direction.

[0122] It is understandable that the guide member 25 ensures that the outer ring support wheel 24 and the outer ring support plate 22 can smoothly transition. Fig.18 The rotating table 105 is arranged to determine that the deformation of the left and right ends of the rotating table 105 is the largest. During the rotation of the rotating table 105, the outer ring supporting wheel 24 first contacts the guide member 25, and the guide member 25 is used to offset the unstable movement caused by the deformation of the platform after the rotating trolley 100 is unloaded, so that the rotating table 105 can move smoothly to the top of the outer ring supporting wheel 24.

[0123] In another embodiment, if Fig.18 and Fig.19 As shown, the guide member 25 includes a support seat 251 fixed to the rotating platform 105 and providing a guiding inclined surface, and a buffer material layer disposed on the guiding inclined surface.

[0124] It is understandable that each support seat 251 is fixed to the rotating platform 105 by welding or bolts. During the rotating movement of the rotating platform 105, the outer ring supporting wheel 24 first contacts the support seat 251, and the support seat 251 is used to offset the unstable movement caused by the deformation of the rotating platform 105 after loading, so that the rotating platform 105 can climb up the outer periphery of the outer ring supporting wheel 24 smoothly.

[0125] The provision of the buffer material can reduce the noise generated when the outer ring supporting wheel 24 contacts and rolls on the support seat 251 .

[0126] In this embodiment, the buffer material layer is made of nylon (polyamide). Of course, in other embodiments, the buffer material layer can also be made of polyurethane or other materials, as long as the material can have a buffering effect to reduce the noise generated when the outer ring supporting wheel 24 contacts and rolls on the support seat 251.

[0127] In another embodiment, if Fig.18 and Fig.19 As shown, the inclination angle of the guide slope is 3 to 15 degrees.

[0128] It is understandable that when the inclination angle of the guide slope is too large, the support seat 251 will extend out of the upper surface of the rotating platform 105, which will affect the load of the rotating platform 105. When the inclination angle of the guide slope is too small, the slope of the guide slope may not be able to offset the unstable movement caused by the deformation of the rotating platform 105 after loading, and the rotating platform 105 may not be able to climb up the outer periphery of the outer ring supporting wheel 24 smoothly.

[0129] The inclination angle of the guide slope is 10 to 12 degrees. In this embodiment, the inclination angle of the guide slope is 10 degrees.

[0130] The thin trolley provided in the present application can reduce the occupied height of the garage or reduce the construction cost.

[0131] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0132] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
