Description

Technical Field

[0001] This utility model relates to the technical field of concrete placing vehicles, specifically to a hydraulic concrete placing vehicle. Background Technology

[0002] Concrete placement is a crucial step in building construction. Traditional methods rely heavily on manual labor or simple machinery. Manual placement is not only labor-intensive and inefficient, but also struggles to ensure uniform placement, making it unsuitable for large-scale construction needs. To overcome these challenges, those skilled in the art have actively explored solutions. For example, the concrete precast component placement system disclosed in Chinese Patent Publication No. CN215702705U represents a certain improvement, but existing concrete placement equipment still has shortcomings. The placement range is limited, requiring frequent equipment movement to cover large construction areas, leading to extended construction time and increased costs; the equipment's steering and movement control are not flexible and precise enough, making it difficult to adapt to complex sites. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a concrete hydraulic placing trolley.

[0004] The technical solution adopted in this utility model is as follows: A concrete hydraulic placing trolley includes a frame, and a hydraulic control mechanism, a placing drive mechanism, and a steering and traveling mechanism mounted on the frame, wherein: The hydraulic control mechanism includes a gasoline engine oil pump group located on the side of the frame, and a hydraulic oil pump station and a hydraulic control valve group located inside the frame. The hydraulic oil pump station is connected to the gasoline engine oil pump group and the hydraulic control valve group respectively. The power of the gasoline engine oil pump group drives the hydraulic oil of the hydraulic oil pump station to enter the hydraulic control valve group. The fabric-laying drive mechanism includes a fabric-laying valve assembly located in the middle of the frame, as well as a fabric-laying pipe and a feed inlet connected to the fabric-laying valve assembly. The feed inlet located at the bottom of the frame passes through the fabric-laying valve assembly and is connected to the fabric-laying pipe located at the top of the frame. The fabric-laying valve assembly drives the fabric-laying pipe, which is bent in an L-shape, to rotate 360°. The steering and traveling mechanism includes a steering valve assembly and a traveling valve assembly located on the front and rear sides of the frame. The steering valve assembly includes a connecting seat and two parallel steering cylinders located on the connecting seat. The traveling valve assembly includes two parallel drive cylinders located on the wheels. The hydraulic control valve group is connected to the material placing valve group, the steering valve group, and the travel valve group, respectively.

[0005] This technical solution achieves coordinated control of the placing boom rotation, trolley steering, and travel by centralizing the hydraulic control mechanism, placing boom drive mechanism, and steering and travel mechanism on the frame, ultimately achieving efficient and flexible concrete placing. Specifically, the gasoline engine oil pump group provides initial power, driving the hydraulic oil pump station to generate high-pressure hydraulic oil, which is distributed to the placing boom drive mechanism and steering and travel mechanism via the hydraulic control valve group. The placing valve group uses hydraulic energy to drive the placing boom to rotate, and the placing boom drive mechanism drives the placing boom to rotate 360°, expanding the placing range, reducing manual adjustments, and improving placing efficiency. The steering valve group and travel valve group control the trolley's steering and travel respectively through the extension and retraction of hydraulic cylinders, ensuring flexible steering and smooth travel to adapt to different construction site requirements.

[0006] In addition, the concrete hydraulic placing trolley proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the frame is further provided with an electrical control box and a battery. The electrical control box is electrically connected to the hydraulic oil pump station, the hydraulic control valve group, the battery, the fabric laying drive mechanism, and the steering and walking mechanism, respectively. The hydraulic control valve group is electrically connected to the fabric laying drive mechanism and the steering and walking mechanism, respectively. The electrical control box realizes the fabric laying, steering, and walking actions by controlling the opening and closing of the hydraulic control valve group.

[0007] In this technical solution, the electrical control box is integrated in the middle of the frame, which facilitates wiring with the surrounding structure of the frame. The electrical control box controls the opening and closing of the valves in the valve group, thereby regulating the flow direction and flow rate of the hydraulic oil, so that the hydraulic oil acts on the fabric drive mechanism and the steering and walking mechanism to realize the fabric laying, steering and walking actions, and improve the fabric laying quality.

[0008] According to one embodiment of the present invention, a shell is also provided on the top of the frame.

[0009] In this technical solution, the shell is convex and covers the hydraulic oil pump station, hydraulic control valve group, electrical control box and battery inside the frame, providing them with protection.

[0010] According to one embodiment of the present invention, the material distribution valve assembly includes a material distribution cylinder, a turbine, a worm gear, and a rotating seat, wherein: the material distribution cylinder drives the turbine to rotate through the worm gear; the middle part of the turbine is connected to the side of the rotating seat, and the turbine drives the rotating seat to move; the upper and lower ends of the rotating seat are respectively connected to the feed pipe and the material distribution pipe, and the concrete slurry flows through the feed pipe, the rotating seat, and the material distribution pipe respectively to perform 360° rotational material distribution.

[0011] This technical solution utilizes a hydraulically driven placing cylinder to perform linear motion, which in turn rotates a worm gear. The worm gear transmits this rotation to a turbine, causing the turbine to rotate a connected rotating base. This, in turn, changes the relative position of the feed pipe and the placing pipe, which are connected vertically to the rotating base. The placing pipe includes a vertical section connected to the rotating base and a horizontally extending section, the length of which is 1.5 to 2.5 times the length of the frame. 360° rotating placing allows for coverage of a larger construction area, reduces equipment movement, and improves placing efficiency.

The front axle drive mechanism includes a steering cylinder II, a front axle connecting seat, a drive cylinder II, and a front wheel. The front axle drive mechanism is connected to the frame through the front axle connecting seat. Two steering cylinders II are installed on both sides of the front axle connecting seat. Each front wheel is fixed below the corresponding steering cylinder II by a bracket. The two drive cylinders II are connected to the corresponding front wheel.

[0013] According to one embodiment of the present invention, the two steering cylinders I are connected in parallel to the hydraulic control valve group for independently controlling the steering of the rear wheels; the two drive cylinders I are connected in parallel to the hydraulic control valve group for independently controlling the movement of the rear wheels; the two steering cylinders II are connected in parallel to the hydraulic control valve group for independently controlling the steering of the front wheels; and the two drive cylinders II are connected in parallel to the hydraulic control valve group for independently controlling the movement of the front wheels.

The electrical control box is centrally located for easy wiring. The shell provides protection for the internal components, reduces space occupation, and makes the overall structure of the trolley more compact, which is convenient for transportation and installation.

[0015] (2) The fabric uses an independent valve group, with two parallel valve groups for steering and walking. This allows for independent and precise control of the fabric tube rotation, front and rear wheel steering and walking, without interference between them, thus improving the accuracy of each action and enhancing the fabric quality.

[0025] like Figures 1 to 6 As shown, this technical solution achieves coordinated control of the rotation of the concrete placing pipe 41, the steering of the trolley, and its movement by centralizing the hydraulic control mechanism, the concrete placing drive mechanism 4, and the steering and walking mechanism on the frame 1, ultimately achieving efficient and flexible concrete placing. Specifically, the gasoline engine oil pump group 3 provides initial power, driving the hydraulic oil pump station 11 to generate high-pressure hydraulic oil, which is distributed to the concrete placing drive mechanism 4 and the steering and walking mechanism via the hydraulic control valve group 12; the concrete placing valve group 42 uses hydraulic energy to drive the concrete placing pipe 41 to rotate, and the concrete placing drive mechanism 4 drives the concrete placing pipe 41 to rotate 360°, expanding the placing range, reducing manual adjustment, and improving placing efficiency; the steering valve group and the walking valve group control the steering and movement of the trolley respectively through the extension and retraction of the hydraulic cylinders, resulting in flexible steering and smooth movement, adapting to the needs of different construction sites.

[0026] In addition, the concrete hydraulic placing trolley proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the frame 1 is further provided with an electrical control box 13 and a battery 14.

[0028] According to one embodiment of the present invention, a shell 2 is also provided on the top of the frame 1.

[0029] In this technical solution, the housing 2 is convex and covers the hydraulic oil pump station 11, hydraulic control valve group 12, electrical control box 13 and battery 14 inside the frame 1, providing them with protection.

[0030] According to one embodiment of the present invention, the material distribution valve assembly 42 includes a material distribution cylinder, a turbine, a worm gear, and a rotating seat, wherein: the material distribution cylinder drives the turbine to rotate through the worm gear; the middle part of the turbine is connected to the side of the rotating seat, and the turbine drives the rotating seat to move; the upper and lower ends of the rotating seat are respectively connected to the feed pipe and the material distribution pipe 41, and the concrete slurry flows through the feed pipe, the rotating seat, and the material distribution pipe 41 respectively to perform 360° rotational material distribution.

[0031] This technical solution utilizes a hydraulically driven placing cylinder to perform linear motion, which in turn rotates a worm gear.
