Description

Technical Field

[0001] This utility model relates to the field of concrete pump technology, specifically to a concrete pump with a rotatable mine car wheel. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates, water, and, when necessary, admixtures and additives in a certain proportion, uniformly stirring, compacting, and curing. A concrete pump, also known as a concrete delivery pump, is a machine that uses pressure to continuously transport concrete along a pipeline. It is mainly used in building construction, bridge and tunnel construction. With the development of urban construction, concrete delivery pumps often need to be used in conjunction with hoppers when they are working.

[0003] For example, concrete pump assemblies for pumping liquid concrete are used in truck-mounted or stationary concrete pumps. Known concrete pump assemblies, for example, include two feed cylinders that alternately draw in and deliver concrete. Here, each feed cylinder is moved by a hydraulically driven cylinder. The hydraulic components required for this (such as piping, hoses, and / or valves) are typically separate and do not provide any support function. A so-called oscillating plate is an exception, which connects two cylinders to its underside and allows oil to flow between the two cylinders. Since each feed cylinder is moved by a hydraulically driven cylinder, errors in the operation of the two hydraulically driven cylinders can lead to errors in the pumped concrete, affecting pumping efficiency. Utility Model Content

[0004] This invention aims to solve the above-mentioned technical problems by providing a concrete pump with a rotatable mine car wheel.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A concrete pump with rotatable mine car wheels includes a pump truck, on which a frame is mounted. A storage tank for storing concrete is installed within the frame. A pump pipe communicating with the storage tank is installed on one side of the storage tank. A piston is installed within each pump pipe, and a piston rod is installed on one side of each piston.

[0007] The frame is equipped with a drive device that pushes two piston rods to make the piston move back and forth inside the pump pipe.

[0008] The storage box is equipped with a conveying device that can be movably connected to either of the two pump pipes.

[0009] Preferably, the driving device includes a first telescopic rod and a fixed shaft fixedly connected within the frame. A rotating disk is connected to the outer side of the fixed shaft via a bearing. Two sets of movable arms are mounted on the outer side of the rotating disk, and the two sets of movable arms are respectively hinged to two piston rods.

[0010] Preferably, one end of the first telescopic rod is hinged to the side wall of the frame, the telescopic end of the first telescopic rod is fixed with a professional fixing ring, and the lower end of the rotating disk is equipped with a limiting shaft and the fixing ring is fitted on the outside of the limiting shaft.

[0011] Preferably, the conveying device includes a connecting shaft inside a storage box, a flexible hose for concrete output, and a second telescopic rod. A movable ring is movably connected to the outside of the connecting shaft, and a first connecting rod and a second connecting rod for driving the flexible hose to rotate are installed on the outside of the movable ring. The telescopic end of the second telescopic rod is hinged to the second connecting rod.

[0012] Preferably, the storage box is equipped with a housing, and the tail of the second telescopic rod is hinged to the side wall of the housing.

[0025] The present invention will now be described in further detail in conjunction with the full text.

[0026] Combined with appendix Figures 1-4 A concrete pump with a rotatable mine car wheel includes a pump truck 1, a frame 2 installed on the pump truck 1, a storage box 3 for storing concrete installed inside the frame 2, a pump pipe 4 connected to the storage box 3 installed on one side of the storage box 3, a piston 5 installed inside each pump pipe 4, a piston rod 6 installed on one side of the piston 5, and a conveying device 8 installed on the storage box 3 that can movably connect to either of the two pump pipes 4.

[0027] In specific implementation of this utility model, such as Figure 1 , Figure 3 and Figure 4As shown, a drive device 7 is installed inside the frame 2 to push two piston rods 6 to drive the piston 5 to move back and forth inside the pump pipe 4. The drive device 7 includes a first telescopic rod 701 and a fixed shaft 702 fixedly connected inside the frame 2. A rotating disk 703 is connected to the outer side of the fixed shaft 702 by a bearing. Two sets of movable arms 704 are installed on the outer side of the rotating disk 703. The two sets of movable arms 704 are respectively hinged to the two piston rods 6. One end of the first telescopic rod 701 is hinged to the side wall of the frame 2. A fixing ring 705 is installed at the telescopic end of the first telescopic rod 701. A limiting shaft 706 is installed at the lower end of the rotating disk 703, and the fixing ring 705 is fitted on the outer side of the limiting shaft 706. When the first telescopic rod 701 is working, it pushes the limiting shaft 706 through the fixed ring 705, which drives the rotating disk 703 to rotate, thereby causing the two movable arms 704 to swing, and driving the two piston rods 6 to compress one and work, so that one of the two pump pipes 4 is connected to the storage box 3 to absorb concrete into the pump pipe 4, and the other is connected to the hose 803 to pump out concrete.

[0028] In specific implementation of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, a conveying device 8 is installed on the storage box 3, which can movably connect to either of the two pump pipes 4. The conveying device 8 includes a connecting shaft 801 inside the storage box 3, a flexible hose 803 for concrete output, and a second telescopic rod 806. A movable ring 802 is movably connected to the outside of the connecting shaft 801. A first connecting rod 804 and a second connecting rod 805 are installed on the outside of the movable ring 802 to drive the hose 803 to rotate. The telescopic end of the second telescopic rod 806 is hinged to the second connecting rod 805. A housing 9 is installed on the storage box 3. The tail of the second telescopic rod 806 is hinged to the side wall of the housing 9. Specifically, the second telescopic rod 806 of the conveying device 8 drives the movable ring 802 to rotate outside the connecting shaft 801, thereby driving the hose 803 to rotate through the connecting rod 804, so that the hose 803 rotates from connecting to the other pump pipe 4 to connecting to the other pump pipe 4.

[0029] Specifically, the second telescopic rod 806 is inclined, which makes it easier to rotate the hose 803 to a suitable position. The angle and extension can be set according to the actual situation.

[0030] The pump truck 1 uses rotatable mining wheel wheels. Specifically, rotatable mining wheel wheels are existing technology and will not be elaborated here. Rotatable mining wheel wheels make the pump truck 1 more flexible.

[0031] The working principle of this utility model:

[0032] When concrete is placed in the storage tank 3, the first telescopic rod 701, when in operation, pushes the limiting shaft 706 through the fixed ring 705, causing the rotating disk 703 to rotate. This causes the two movable arms 704 to swing, and drives the two piston rods 6 to perform compression and working motion, so that one of the two pump pipes 4 is connected to the storage tank 3 to absorb concrete into the pump pipe 4, and the other is connected to the hose 803 to pump out concrete. The second telescopic rod 806 of the conveying device 8 drives the movable ring 802 to rotate outside the connecting shaft 801, thereby driving the hose 803 to rotate through the connecting rod 804. This causes the hose 803 to rotate from connecting pump pipe 4 to connecting to another pump pipe 4. The hose 803 connects to pump pipe 4 to pump out concrete, and then connects to the outside.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
