For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0036] Reference Figure 1As shown, the embodiment provides a car hoisting device for bottom axle flipper gate, which comprises a car support body 1 and a first support mechanism.

[0037] The car support body 1 is part of the crane, and when the crane is hoisting, the car support body 1 needs to be unfolded first, and the first support mechanism on the car support body 1 is against the ground to support and stabilize the whole crane. Generally, the car support body 1 is a long shaft type support, which has two ends, which can be defined as the first end and the second end respectively. The first end of the car support body 1 is connected to the crane body, and the second end of the car support body 1 is used to install the support mechanism for supporting and stabilizing the whole car hoisting device.

[0038] The first support mechanism, as the main support leg of the car hoisting device, bears most of the force of the crane, reduces the load borne by the car support body 1, ensures the balance of the crane during hoisting operation, and prevents overturning due to excessive load or improper operation.

[0039] The first support mechanism comprises a first telescopic oil cylinder 4 and an expansion mechanism 2, the first telescopic oil cylinder 4 is fixed through the second end of the car support body 1, the output end of the first telescopic oil cylinder 4 is fixedly connected with the expansion mechanism 2, and the expansion mechanism 2 comprises an expansion assembly 21. The first telescopic oil cylinder 4 is used as the leg part of the first support mechanism, and the vehicle is lifted away from the ground by the telescopic expansion of the first telescopic oil cylinder 4, so as to support it. At the same time, the output end of the first telescopic oil cylinder 4 is connected with the expansion mechanism 2, and the expansion mechanism 2 comprises the expansion assembly 21 which can be expanded outward, so as to improve the contact area between the first support mechanism and the ground and further improve the stability of the crane.

[0040] Referring to Figure 2 and Figure 3 As shown, the expansion assembly 21 comprises a support seat 211, a first motor 212, a driving bevel gear 213 and a plurality of extension components, the support seat 211 is a hollow structure and is fixedly connected with the output end of the first telescopic oil cylinder 4, the first motor 212 is fixedly installed inside the support seat 211 and is coaxially arranged with the first telescopic oil cylinder 4, the driving bevel gear 213 is coaxially fixed with the output shaft of the first motor 212, and each extension component comprises a driven bevel gear 214, a threaded rod 215, a sliding frame 216 and an expansion plate 217, the driven bevel gear 214 is rotatably installed inside the support seat 211 and is perpendicularly meshed and connected with the driving bevel gear 213, the threaded rod 215 is rotatably installed inside the support seat 211 and is coaxially fixed with the driven bevel gear 214, the first end of the sliding frame 216 is threadedly sleeved on the threaded rod 215 and the second end penetrates through the side wall of the support seat 211, and the expansion plate 217 is fixedly connected with the second end of the sliding frame 216.

[0041] The support base 211 is a hollow structure, an annular plate is fixed coaxially inside the support base 211, the driven bevel gears 214 are rotatably installed on the side wall of the annular plate, the threaded rods 215 horizontally penetrate the side wall of the annular plate, and the sliding frame 216 is U-shaped, the bottom end of the sliding frame 216 is threadedly connected to the threaded rod 215. When it is necessary to improve the support stability, the output shaft of the first motor 212 inside the support base 211 is controlled to rotate, the driving bevel gear 213 fixed coaxially with the output shaft of the first motor 212 starts to rotate, then the driven bevel gears 214 vertically meshed and connected with the driving bevel gear 213 start to rotate, each driven bevel gear 214 drives the threaded rod 215 fixed coaxially with the driven bevel gear 214 to rotate, and then drives the sliding frame 216 to slide horizontally, so that the plurality of expansion plates 217 slide out of the side wall of the support base 211 and away from the support base 211, thereby increasing the contact area of the support base 211 with the ground, reducing the ground pressure of the contact area, avoiding the situation that the support base 211 sinks into the ground, and making the support base 211 (ground) support the automobile more stably, thereby effectively avoiding the crane overturning situation, increasing the stability of the lifting, and solving the problem that the traditional automobile lifting cannot stably lift the bottom shaft flip plate gate.

[0042] Further, the support base 211 is a square plate structure, the extension components are four, and the threaded rods 215 in the four extension components are perpendicular to the four sides of the plate structure. The extension components extend from the four edges of the support base 211 and jointly increase the contact area of the support base 211 with the ground. The uniform distribution of the extension components can more effectively disperse the load, avoid that a single extension component bears too large load, and thereby improve the carrying capacity of the automobile lifting. Correspondingly, in other embodiments, the plate structure can be a circular or other axial symmetric figure.

[0043] Referring to Figure 4 As shown in FIG. 1, in some embodiments, the expansion mechanism further comprises a plurality of stabilizing assemblies, each stabilizing assembly 22 comprises a flip plate 221 and a plurality of ground anchors 222, the lower end of the flip plate 221 is rotatably connected to one side of the expansion plate 217 away from the sliding frame 216, and the plurality of ground anchors 222 are fixedly connected to one side of the flip plate 221 away from the expansion plate 217. Each expansion plate 217 is provided with a pair of lockable locking components, and the locking components are used to limit the rotation of the flip plate 221.

[0044] In the above embodiments, when the plurality of stretching components are extended out of the side wall of the support base 211, when the turnover plate 221 is in the locked state, the turnover plate 221 is in the parallel state with the expansion plate 217, after the locking component is opened, the turnover plate 221 on each expansion plate 217 is turned over 90° to the ground, the plurality of ground-piercing blocks 222 on the surface of the turnover plate 221 can increase the friction between the device and the ground, reduce the possibility of the support base 211 being offset and tilted, and further improve the support stability of the support base.

[0045] Further, the cross section of each ground-piercing block 222 is triangular. The triangular shape can make the sharp part of the ground-piercing block 222 more easily penetrate into the ground, thereby increasing the friction between the device and the ground.

[0046] Referring to Figure 4 As shown in some embodiments, each locking component includes a U-shaped fixed frame 223, an insertion block 228, a pull rod 225, and a pull ring 226, the U-shaped fixed frame 223 is fixedly connected to the surface of the expansion plate 217, the insertion block 228 is slidingly installed inside the U-shaped fixed frame 223, the side wall of the turnover plate 221 is provided with an insertion slot matched with the insertion block 228, the first end of the insertion block 228 can be slid out of the U-shaped opening of the U-shaped fixed frame 223 and embedded into the insertion slot to limit the rotation of the turnover plate 221, the second end of the insertion block 228 is fixedly connected with the pull rod 225, and the end of the pull rod 225 away from the insertion block 228 is slidingly inserted into the U-shaped fixed frame 223 and fixedly connected with the pull ring 226.

[0047] In the above embodiments, each locking component is arranged at the corner of the upper end of the expansion plate 217, and the left and right side walls of the upper end of the turnover plate 221 are provided with insertion slots corresponding to the insertion block 228, in the locked state, the insertion block 228 is inserted into the insertion slot, and the turnover plate 221 is thus limited on the expansion plate 217, maintaining the parallel state; when unlocking is needed, the pull ring 226 can drive the pull rod 225 to slide horizontally, so as to make the insertion block 228 in the U-shaped fixed frame 223 pull out of the insertion slot of the side wall of the turnover plate 221, thereby achieving the unlocking of the turnover plate 221 by the locking component.

[0048] Further, each pull rod 225 is sleeved with a spring 224, and the two ends of the spring 224 are respectively abutted with the insertion block 228 and the inner wall of the U-shaped fixed frame 223. When the pull ring 226 is pulled, the insertion block 228 will slide along the U-shaped fixed frame 223 and compress the spring 224. After the pull ring 226 is released, the insertion block 228 will reset under the elastic potential energy of the spring 224. The spring 224 is arranged to facilitate the opening and unlocking of the locking part, and can reduce the influence of external factors on the locking part, and prevent the insertion block 228 from sliding out of the slot accidentally. Exemplarily, each turnover plate 221 is rotationally connected with the expansion plate 217 through a torsion spring 227. In the locked state, the torsion spring 227 is in a compressed state. Once the locking part is opened, the turnover plate 221 will automatically rotate around it under the elastic potential energy of the torsion spring 227, and the elastic force of the torsion spring 227 will also exert a pressure on the turnover plate 221 relative to the ground, further increasing the friction between the ground block 222 and the ground.

[0049] In order to further improve the support stability, a second support mechanism can also be arranged at the second end of the automobile support body 1, and the support stability is improved by multi-point support. Correspondingly, referring to Figure 5 In some of the embodiments, each second support mechanism 3 includes a second motor 31, a rotating rod 34, a second telescopic oil cylinder 35, and a support block 36. The second motor 31 is fixedly installed at the second end of the automobile support body 1. The second motor 31 is connected with the first end of the rotating rod 34 through a transmission component and drives the rotating rod 34 to rotate around the first end thereof. The second end of the rotating rod 34 is fixedly connected with the second telescopic oil cylinder 35. The second telescopic oil cylinder 35 is parallel to the first telescopic oil cylinder 4. The support block 36 is fixedly connected with the output end of the second telescopic oil cylinder 35.

[0050] In the above-mentioned embodiments, when the second support mechanism 3 needs to be opened, the output shaft of the second motor 31 is controlled to start rotating. Through the linkage of the transmission component, the rotating rod 34 slowly rotates and expands with the second telescopic oil cylinder 35. Then, the second telescopic oil cylinder 35 is adjusted to keep the same length as the first telescopic oil cylinder 4. When a pair of second support mechanisms 3 are completely expanded, a triangular support structure is formed together with the first support mechanism, and the three legs jointly bear the force, thereby increasing the stability of the device as a whole.

[0051] Further, the support block 36 is circular in cross section, and can be used as the base of the leg to increase the force bearing area of the leg on the ground and improve the stability of the support.

[0052] Referring to Figure 6As shown, in some of the embodiments, each transmission component comprises a driving spur gear 32 coaxially fixed with the output shaft of the second motor 31 and a driven spur gear 33 rotatably mounted on the mounting block 5 and engaged with the driving spur gear 32, the driven spur gear 33 being fixedly connected with the first end of the rotating rod 34.

[0053] In the above embodiment, the rotation of the output shaft of the second motor 31 drives the coaxially fixed driving spur gear 32 to rotate, and then drives the driven spur gear 33 to rotate, and the driven spur gear 33 drives the rotating rod 34 to rotate.

[0054] The utility model discloses a control support seat 211 inside the output shaft rotation of first motor 212 drives the coaxially fixed driving bevel gear 213 to start rotating, and then by driving bevel gear 213 drives a plurality of perpendicular meshing connection driven bevel gear 214 starts rotating, and each driven bevel gear 214 drives the coaxially fixed threaded rod 215 to rotate respectively, and then drives sliding frame 216 horizontal sliding respectively, and the plurality of expansion plate 217 slides and goes out the lateral wall of support seat 211 and is far away from support seat 211, and further increase the contact area of support seat 211 and ground, make the ground pressure intensity of contact area reduce, and further not easy appear the situation that support seat 211 sinks into ground, make support seat 211 (ground) to the car support more stable, can effectively avoid the crane rollover situation, increase the stability of hoisting, solved the problem that traditional car hoisting can not stably hoist the bottom axle flap gate.

[0055] Further, by setting a pair of second support mechanisms 3, the first support mechanism and the second support mechanism 3 jointly form a triangular support structure, avoiding supporting through a single support leg, greatly improving the safety of the car during the hoisting operation of the bottom axle flap gate, and providing safety protection for the hoisting operation.

According to the embodiments provided in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
