[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-3 A cement silo base frame includes a base frame 10 and four hydraulic outriggers 20. Four movable connectors A are fixed on the base frame 10. Each movable connector A is detachably connected to a movable connector B. The movable connector B is fixed on the hydraulic outriggers 20.

[0026] The phrase "fixing four movable connectors A on the base frame 10" in this article can mean "fixing new components on the base frame 10" or "a certain part of the base frame 10 has the function of connecting with movable connectors B to form movable connectors A".

[0027] For easy disassembly, movable connector A is a sleeve 11, and movable connector B is inserted into sleeve 11.

[0028] For easy disassembly, the sleeve 11 is horizontally arranged.

[0029] For stability, the four sleeves 11 are fixed at the four corners of the chassis 10.

[0030] For easy support during operation, a mechanical leg connecting part 18 is fixed at each corner of the chassis 10.

[0031] During manufacturing, the hydraulic leg 20 can be equipped with an oil pump (similar to a hydraulic cylinder), or can not be equipped with an oil pump, and is provided with a quick connector 29 connected to an external oil pump.

[0032] The movable connecting part B can have two specific structures:

[0033] The first structure

[0034] As shown in Figures 1-3 , the movable connecting part B is a parallel plug-in part 21, which is arranged parallel to the sleeve 11, and when the parallel plug-in part 21 is inserted into the sleeve 11, the axis of the parallel plug-in part 21 coincides with the axis of the sleeve 11.

[0035] For stability, the parallel plug-in part 21 is fixed at the middle part of the hydraulic leg 20, and the parallel plug-in part 21 and the hydraulic leg 20 form a T-shaped structure as a whole.

[0036] For stability, the parallel plug-in part 21 and the sleeve 11 are straight prismatic in shape, so that they are similar to key connection, and the whole structure is more stable.

[0037] The second structure

[0038] As shown in Figures 4-7 , the movable connecting part B is a vertical plug-in part 26, which is arranged perpendicular to the sleeve 11, and when the parallel plug-in part 21 is inserted into the sleeve 11, the axis of the parallel plug-in part 21 is perpendicular or oblique to the axis of the sleeve 11, Figure 5 which means that the axis of the parallel plug-in part 21 is perpendicular to the axis of the sleeve 11.

[0039] For stability, the vertical plug-in part 26 is fixed at the end of the hydraulic leg 20.

[0040] For stability, the lower end of the vertical plug-in part 26 is fixed with a support flange 25, and the upper surface of the flange 25 is matched in shape with the lower surface of the sleeve 11, and when the parallel plug-in part 21 is inserted into the sleeve 11, the upper surface of the flange 25 is matched in shape with the lower surface of the sleeve 11.

[0041] The working principle is as follows:

[0042] In the scheme, one tea pot can match multiple tea cups, and one transport vehicle can match multiple cement bins. The four hydraulic legs 20 move together with the transport vehicle. When the transport vehicle is disassembled, the hydraulic legs can be used (see below for details). When the cement bin enters the working state (the working state is to cooperate with the mixer for construction, which generally needs to be continuous for a period of time without moving), the transport vehicle moves another cement bin with the hydraulic legs 20. In this way, the use efficiency of the hydraulic legs is improved, and the system cost is saved.

[0043] It includes the following steps:

[0044] S10, loading, including steps S11-S15.

[0045] S11, installing hydraulic legs: shortening the four hydraulic legs, and inserting the movable connecting piece B into the sleeve 11 of the chassis of the cement bin.

[0046] S12, jacking up: lengthening the four hydraulic legs, and inserting the movable connecting piece B into the sleeve 11 of the chassis of the cement bin to lift the chassis and the cement bin.

[0047] S13, transport vehicle in place: driving the transport vehicle under the chassis.

[0048] S14, complete loading: shortening the four hydraulic legs, and lowering the chassis and the cement bin on the transport vehicle to complete the loading.

[0049] S15, disassembling the hydraulic legs: disassembling the four hydraulic legs from the chassis and placing them on the transport vehicle.

[0050] S20, unloading (also on-site installation), including steps S21-15.

[0051] S21, installing hydraulic legs: shortening the four hydraulic legs, and inserting the movable connecting piece B into the sleeve 11 of the chassis of the cement bin.

[0052] S22, jacking up: lengthening the four hydraulic legs, and inserting the movable connecting piece B into the sleeve 11 of the chassis of the cement bin to lift the chassis and the cement bin.

[0053] S23, installing mechanical legs: installing the four mechanical legs on the mechanical leg connecting part 18 of the chassis 10.

[0054] It should be noted that in this step, if there is no mechanical leg, other support platforms can also be used as long as they can ensure stable working posture. When the cement bin needs a certain support height, the mechanical legs continue to provide support, and at the same time the hydraulic legs can be applied to other vehicles, improving the utilization rate of equipment

[0055] S24, complete field installation: four hydraulic legs are shortened, the lower part of the mechanical leg contacts the ground, and the field installation is completed.

[0056] S25, remove the hydraulic legs: four hydraulic legs are removed from the chassis and placed on the transport vehicle.

[0057] During the transportation of the cement silo on the transport vehicle, four hydraulic legs also need to be placed on the vehicle. If there is no space on the vehicle, the transportation burden is increased. At this time, if the parallel plug-in part 21 and the sleeve 11 are straight prismatic in shape matching, Figure 3 the hydraulic legs can be set horizontally (that is, the hydraulic legs are changed in the plug-in direction, and the hydraulic legs are in the plane with the vehicle frame), so that the overall height of the chassis is lower, which is convenient for vehicle driving, and can also be adapted to any cement silo transport vehicle on the market.

[0058] The features of the present application are:

[0059] 1. The hydraulic legs realize the use of multiple vehicles and multiple models of vehicles, realize the adaptation of one leg to multiple vehicles, and reduce the operation and maintenance cost.

[0060] 2. The hydraulic legs can also be used in cooperation with the mechanical legs. When the cement silo needs a certain support height, the mechanical legs continue to provide support, and at the same time, the hydraulic legs can be applied to other vehicles, thereby improving the utilization rate of the equipment.

[0061] 3. The hydraulic legs can be flattened by changing the plug-in direction, thereby adapting to any cement silo transport vehicle on the market.

[0062] Other contents refer to the prior art.

[0063] The above is only the preferred embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, some changes and improvements can be made, which should also be considered as the protection range of the present application.
