Description

Technical Field

[0001] The utility model belongs to the technical field of powder material storage and transportation, and specifically relates to a rotatable hydraulic support device and a silo made of the device. Background Art

[0002] Referring to Chinese patent document CN114751099A, the chassis 140 is fixed with four hydraulic legs 141. When the bulk material storage device is loaded onto a vehicle, the hydraulic legs 141 are extended, the height of the chassis 140 is increased, and the vehicle is convenient to enter the lower part of the chassis 140; the hydraulic legs 141 are shortened, the height of the chassis 140 is decreased, and the chassis 140 is pressed on the vehicle to complete the loading. This provides convenience for the coordination between the bulk material storage device and the transport frame.

[0003] However, because the lower end of the hydraulic support leg 141 extends beyond the lower surface of the chassis, it will affect the frame of an ordinary transport vehicle, and a special vehicle chassis needs to be used, such as Chinese patent document CN214822823U, which discloses a loading and unloading positioning vehicle-mounted device. This technical solution achieves rapid and accurate positioning and fastening of the vehicle-mounted base and the vehicle chassis through front and rear positioning devices, left and right positioning devices and quick fastening devices, aiming to improve the loading and unloading efficiency and ease of use of transport vehicles.

[0004] This device is particularly suitable for scenarios where heavy-duty transport vehicles are loaded with irregular large cargoes. It solves the problem that ordinary flatbed frames cannot be accurately positioned and connected to the chassis and are not convenient for loading and unloading at any time, and overcomes the shortcomings of low transportation efficiency and inconvenient loading and unloading in the prior art.

[0005] However, although this patented technical solution has significant advantages in improving the efficiency and convenience of specific transportation scenarios, it also faces some limitations in practical application.

[0006] First, since the device requires the vehicle base to match the vehicle chassis, it means that it belongs to a special vehicle or requires a qualified modified vehicle. The entry threshold for special vehicles and modified vehicles is high, and the qualification requirements of relevant national departments are high. The required costs are also very high, and often specific procedures are required to operate, which increases transportation costs and complexity.

[0007] Secondly, special-purpose vehicles are not universal and may not be suitable for all roads.

[0008] Finally, the size of the cargo compartment on the vehicle base is usually fixed, which limits the flexibility of the amount of cargo to be transported. If the amount of cargo to be transported is small, it is not economical to use such a special vehicle, and the transportation scenario it adapts to is not flexible enough. Utility Model Content

[0009] The technical problem to be solved by the utility model is: how to design a relatively rotatable hydraulic support device and a silo made of the same, so as to facilitate the coordination of the silo with a common flatbed vehicle frame.

[0010] The technical solution of the utility model is specifically as follows:

[0011] A rotatable hydraulic support device comprises a support member, the support member is hinged to a hydraulic support leg, the support member is fixed to a cylinder seat fixing frame, the cylinder seat fixing frame is hinged to one end of a leg-turning oil cylinder, and the other end of the leg-turning oil cylinder is hinged to the hydraulic support leg.

[0012] The support member is fixed on the chassis or is directly a part of the chassis. When the support member is a part of the chassis, the cylinder seat fixing frame is an independent component or is also a part of the chassis.

[0013] The support is a mobile crossbeam and mobile articulated hydraulic legs;

[0014] The connection between the chassis and the rotatable hydraulic support device is specifically as follows: a sleeve is fixed on the chassis, the sleeve is arranged along the width direction of the chassis, and the movable crossbeam is inserted into the sleeve and can slide along it.

[0015] The movable crossbeam and the sleeve are form-fitted or key-fitted.

[0016] The leg tilting cylinder is located above the hydraulic legs.

[0017] Two hinged plates A are fixed on the sides of the outer end of the movable crossbeam, and a hinged plate B is fixed on the hydraulic leg. When the hydraulic leg is in a vertical state, the hinged plate B is located between the two hinged plates A, and the hinged plate B and the two hinged plates A are hinged together through a pin shaft.

[0018] A silo comprises a silo body, wherein the silo body is connected above a base frame, and the base frame is connected to four of the above-mentioned hydraulic support devices.

[0019] Four rotatable hydraulic support devices are respectively distributed at four corners of the chassis.

[0020] The hinge plate is provided with a pin hole A, and the base frame is also provided with a pin hole B corresponding thereto. When the hydraulic support leg is in a vertical state, a pin is passed through the pin hole A and the pin hole B.

[0021] When the hydraulic legs are in a horizontal state, the hydraulic legs are located at the front side or the rear side of the chassis.

[0022] Compared with the prior art, the technical effect of the utility model is that the utility model hinges the legs on the base frame of the silo, the legs can be adjusted to a horizontal state and will not exceed the lower surface of the base frame, so that the base frame can be stably placed on an ordinary flatbed frame, which is more convenient.

[0027] The utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1-2 A silo includes a silo body 10, which is connected to the top of a base frame 19, and the base frame 19 is connected to four rotatable hydraulic support devices.

[0029] like Figure 1-2 The four rotatable hydraulic support devices are respectively distributed at the four corners of the base frame 19.

[0030] like Figure 3 The rotatable hydraulic support device includes a support member, the support member is hinged to the hydraulic support leg 20 (the vertical state of the hydraulic support leg is shown in the number 201, and the horizontal state of the hydraulic support leg is shown in the number 202), the support member fixes the cylinder seat fixing frame 80, the cylinder seat fixing frame 80 is hinged to one end of the leg-tilting cylinder 81 (the piston rod of the leg-tilting cylinder 81 is extended, see the figure mark 801), and the other end of the leg-tilting cylinder 81 is hinged to the hydraulic support leg 20.

[0031] The support member is fixed on the base frame 19 or is directly a part of the base frame 19. When the support member is a part of the base frame 19, the cylinder seat fixing frame 80 is an independent component or is also a part of the base frame 19, as long as it can provide sufficient support for the leg-turning cylinder 81.

[0032] In this case, the hydraulic support leg 20 is equivalent to the base frame 19 being unable to move (the rotation driven by the leg-turning cylinder 81 is not included), that is, the hydraulic support leg 20 cannot approach or move away from the base frame 19. Although the angle between the hydraulic support leg 20 and the horizontal plane can be adjusted, there are still certain limitations.

[0033] To this end, further improvements are made as follows:

[0034] like Figure 3 The supporting member is a moving beam 22 , the outer end of the moving beam 22 is fixed to a cylinder seat fixing frame 80 , and the outer end of the moving beam 22 is hinged to the hydraulic support leg 20 .

[0035] like Figure 3-4The connection between the chassis 19 and the rotatable hydraulic support device is as follows: a sleeve 191 is fixed on the chassis 19, and the sleeve 191 extends along the width direction of the chassis 19 ( Figure 4 The movable cross beam 22 is arranged in the sleeve 191 and can slide along it. In this way, the hydraulic support leg 20 can be close to or away from the chassis 19.

[0036] like Figure 4 The movable cross beam 22 and the sleeve 191 are matched in shape or key to prevent the two from rotating.

[0037] like Figure 3 In order to prevent interference, when the hydraulic leg 20 is in a horizontal state, the leg tilting cylinder 81 is located above the hydraulic leg 20.

[0038] like Figure 4 For the sake of firmness, two hinged plates A231 are fixed on the sides of the outer end of the movable cross beam 22, and a hinged plate B232 is fixed on the hydraulic leg 20. When the hydraulic leg 20 is in a vertical state, the hinged plate B232 is located between the two hinged plates A231, and the hinged plate B232 and the two hinged plates A231 are hinged together through the pin 233.

[0039] like Figure 4 In order to maintain stability, the hinged plate 21 is provided with a pin hole A211, and the base frame 19 is also provided with a corresponding pin hole B (not shown in the figure). When the hydraulic support leg 20 is in a vertical state, a pin is inserted into the pin hole A211 and the pin hole B to prevent the hydraulic support leg 20 from tilting.

[0040] like Figure 4 In order to prevent interference, when the hydraulic support leg 20 is in a horizontal state, the hydraulic support leg 20 is located at the front side or the rear side of the chassis 19.

[0041] Its working principle is:

[0042] Transport silo

[0043] Loading: At the beginning, the moving crossbeam 22 slides to the outside of the sleeve 191, the hydraulic leg 20 is in a vertical state, the distance between the moving crossbeams 22 on both sides increases, the piston rod of the hydraulic leg 20 extends, the height of the chassis 19 increases, and the flat-bottomed frame of the vehicle enters the lower part of the chassis 19; the piston rod of the hydraulic leg 20 contracts, the height of the chassis 19 decreases, and the lower surface of the chassis 19 presses on the flat-bottomed frame of the vehicle, the pin is removed, and the leg-turning cylinder 81 is driven, and its piston rod contracts, and the hydraulic leg 20 is in a horizontal state, see number 202, and then the moving crossbeam 22 is slid to the inside of the sleeve 191, and the hydraulic leg 20 is also located above the flat-bottomed frame of the vehicle, which does not affect the loading. The loading is completed in this way.

[0044] Unloading: When the vehicle arrives at the destination, the moving cross beam 22 slides to the outside of the sleeve 191, driving the leg-tilting cylinder 81, and its piston rod extends. The hydraulic leg 20 is in a vertical state, see the number 201, and a pin is inserted into the pin hole A211 and the pin hole B to prevent the hydraulic leg 20 from tilting; then the piston rod of the hydraulic leg 20 is extended, the height of the base frame 19 becomes higher, leaving the flat-bottomed frame, and the vehicle is driven out.
