[0002] Fixed concrete mixing stations or central factories are widely used in the construction industry for concrete processing and production. However, fixed concrete mixing stations and factories also have certain limitations. For example, in scattered small-scale engineering projects, setting up a single mixing station consumes a lot of financial and material resources. At this time, using a mobile concrete mixing station will be a more reasonable way to save costs.

[0003] The mobile concrete mixing station is towed by a semi-trailer, and has the characteristics of compact structure, small footprint, flexible mobility, rapid assembly and disassembly, high degree of automation, and close proximity to construction sites. It is suitable for construction sites with restricted terrain such as tunnels, bridges, dams, and airports. However, when switching between the transportation state and the working state, the existing domestic mobile mixing stations require lifting equipment to raise or lower the height of the equipment and disassemble the weighing system, batching bin and other accessories. For some construction sites with limited space, it is difficult for the lifting equipment to reach the appropriate position, which brings great difficulties to the installation of the mobile mixing station; in some remote areas in the northwest, due to the scarcity of equipment and long distances, the cost of hiring lifting equipment is very high, which is difficult to meet the needs of use.

[0027] The features and performance of the mobile mixing station with a hydraulic jacking system of the present application are further described in detail below in conjunction with the embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the embodiment of the present application provides a mobile mixing station with a hydraulic jacking system, which includes a main frame 100, one end of the main frame 100 is connected to a pair of rotatable moving wheels 140, and the other end is configured to be connected to a traction vehicle 300, the end of the main frame 100 close to the moving wheel 140 is connected to a batching bin 110, the end of the main frame 100 close to the traction vehicle 300 is connected to a mixing bin 120, and the middle part of the main frame 100 is also connected to a weighing belt conveyor 130 for conveying the material discharged from the bottom of the batching bin 110 to the top feeding port of the mixing bin 120, and the main frame 100 is also connected to a metering device for weighing the material put into the top feeding port of the mixing bin 120; the middle part of the main frame 100 is connected to a hydraulic jacking mechanism for jacking or lowering one end of the main frame 100 close to the mixing bin 120, and the hydraulic jacking mechanism includes a pair of relatively arranged hydraulic oil Cylinder 150 and a hydraulic station 160 for driving the hydraulic cylinder 150 to extend and retract. The hydraulic station 160 is fixed to the middle of the main support 100. Each pair of hydraulic cylinders 150 is connected to the bottom of the main support 100 through corresponding tension springs 170. The hydraulic rods of each pair of hydraulic cylinders 150 face downward and are respectively hinged with a jacking base 210. The two corresponding jacking bases 210 are connected by a connecting rod 220. The bottoms of the two corresponding jacking bases 210 are respectively connected with gripping feet 180. The cylinder bodies of each pair of hydraulic cylinders 150 face upward and are respectively connected with tension springs 170. The bottom of the main support 100 is connected to the two corresponding tension springs 170 through two spring brackets 190. The hydraulic cylinder 150 is provided with a cylinder support 200 connected to the main support 100. The cylinder support 200 consists of a support plate 201 and a]-shaped connecting plate 202 connected to the support plate 201. The bottom of the main frame 100 is also hinged with an operating room support rod 230 that can be rotated to support the ground or fit the main frame 100, and an operating room driving cylinder 240 for driving the operating room support rod 230 to rotate relative to the main frame 100. The operating room support rod 230 is connected to an operating table 250. The two ends of the operating room driving cylinder 240 are respectively hinged to the main frame 100 and the operating room support rod 230. Two pairs of detachable support frames 260 are connected to the bottom of the main frame 100, and the hydraulic cylinder 150 is a three-stage hydraulic cylinder.

[0029] When the mobile mixing station with a hydraulic jacking system provided in this embodiment is used, one end of the main support 100 is detachably connected to the rear of the traction vehicle 300, and the traction vehicle 300 is used to tow the moving wheel 140 of the main support 100 to move. When the transfer is moved to the target location, the main support 100 is separated from the traction vehicle 300, and the hydraulic station 160 controls the oil cylinder rods of a pair of hydraulic oil cylinders 150 to extend, driving the jacking base 210 and the gripping foot 180 connected to the oil cylinder rods of the pair of hydraulic oil cylinders 150 to press the ground, thereby using the reverse thrust to push the main support 100 to move. The end of the frame 100 close to the traction vehicle 300 is raised to a preset height, and then the hydraulic station 160 is used to control the operating room to drive the cylinder rod of the cylinder 240 to extend and drive the operating room support rod 230 to rotate to support the ground. Finally, two pairs of detachable support frames 260 are respectively connected to the two sides of the main frame 100 for support, and the cylinder rods of a pair of hydraulic cylinders 150 are controlled to contract to drive the jacking base 210 and the gripping feet 180 to leave the ground, so that materials can be added to the batching bin 110 and input into the mixing bin 120 through the weighing belt conveyor 130 for mixing and processing to obtain concrete.

[0030] Among them, the mobile mixing station with a hydraulic lifting system provided in this embodiment can stably drive one end of the main support 100 to rise or fall through a pair of hydraulic cylinders 150 arranged in the main support 100, thereby avoiding the need to use external lifting equipment to lift the main support 100, and is suitable for use in remote areas and some narrow environments where it is difficult to transport lifting equipment. The hydraulic cylinder 150 is connected to the main support 100 through a tension spring 170 and a spring bracket 190 connected in sequence. The elastic force of the tension spring 170 can be used to keep the hydraulic cylinder 150 close to the vertical direction to support the main support 100, reduce the offset of the hydraulic cylinder 150, and prevent the cylinder rod of the hydraulic cylinder 150 from colliding with the cylinder support 200 when it is retracted or extended; the hydraulic cylinder 150 is provided with a cylinder support 200 connected to the main support 100, and the cylinder support 200 is composed of a support plate 201 and a]-shaped connecting plate 202 connected to the support plate 201, which can limit the position change of the hydraulic cylinder 150 when it is extended and retracted, ensuring the hydraulic The oil cylinder 150 stably lifts or lowers the main support 100; the hydraulic rods of each pair of hydraulic oil cylinders 150 face downward and are respectively hinged with a lifting base 210, and the two corresponding lifting bases 210 are connected by a connecting rod 220. The bottoms of the two corresponding lifting bases 210 are respectively connected with gripping feet 180, which can ensure that the gripping feet 180 stably press against the ground when the hydraulic oil cylinder 150 extends or retracts the hydraulic rod, and adapt to the angle change between the extended or retracted hydraulic rod and the ground through the lifting base 210 that can rotate relative to the hydraulic rod, and make the hydraulic rod strokes of the two hydraulic oil cylinders 150 consistent, so as to ensure the overall stability of the equipment during the lifting process. In addition, the operator can use the hydraulic station 160 to control the operating room drive oil cylinder 240 to drive the operating room support rod 230 to rotate to support the ground or fit the main support 100, so that the operating room support rod 230 supports the main support 100 while facilitating the operator to climb onto the operating platform 250 connected to the operating room support rod 230 for operation.

[0031] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. 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 the present application.
