Abstract
Description
Technical Field
[0001] This invention relates to the field of concrete mixing equipment technology, and to a device for mixing and preparing concrete on-site, specifically to an ultra-high performance concrete on-site preparation device and a vehicle-mounted mixing system. Background Technology
[0002] In the construction of precast bridges or steel bridge decks, ultra-high performance concrete (UHPC) is laid between the joints of two adjacent precast components.
[0003] Currently, the preparation of ultra-high performance concrete involves transporting the mixer and all supporting equipment to the construction site and connecting an external power source for on-site mixing. The entire system includes an electrical control box, mixer, hydraulic pump station, main water tank, weighing water tank, and other necessary pipelines and wiring. The entire system is not designed in an integrated manner; the components are scattered, often requiring multiple vehicles for transport, and a crane for loading and unloading. Pipelines and wiring must be connected on-site, and the electrical control box must be connected to the external power source before it can be used. Loading, unloading, installation, and commissioning of the equipment require a lot of manpower and resources. At most, only four cubic meters of ultra-high performance concrete need to be mixed at one bridge pier. After mixing, the equipment is loaded onto a truck and transported to the next bridge pier, then unloaded, installed, and commissioned again. This relocation is very inconvenient and the work efficiency is extremely low. Furthermore, there is a significant drawback: the instability of the external power supply. If another high-powered device starts simultaneously while the mixer is working normally at the construction site, it may cause a sudden drop in the grid voltage, leading to the mixer stopping due to insufficient power. If it fails to start normally, a second restart may also fail, resulting in a stall. In this case, the mixer cannot continue to start normally, and all the ingredients inside the mixer box must be manually removed promptly. If the removal is not fast enough, the ultra-high performance concrete may solidify into lumps inside, making the removal even more troublesome.
[0004] In summary, the current high efficiency of ultra-high performance concrete mixing equipment hinders the progress of precast bridge construction and has become the biggest bottleneck in engineering construction. There is an urgent need for a new type of high-efficiency concrete mixing equipment that is easy to use, safe and reliable. Summary of the Invention
[0005] The present invention addresses the aforementioned shortcomings of existing technologies by providing an ultra-high performance concrete on-site mixing equipment that is highly efficient, integrated, miniaturized, containerized, modular, independent, easy to transport, or self-propelled.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An ultra-high performance concrete on-site mixing equipment is disclosed. The ultra-high performance concrete on-site mixing equipment is a frame-type ultra-high performance concrete on-site mixing equipment, including an integrated frame and a hydraulic system, a water supply system and a mixer installed on the frame. The frame includes a first frame part and a second frame part arranged along the longitudinal direction of the frame. A first space is formed in the first frame part, and a second space and a third space are formed in the second frame part. The third space is located above the second space, and an operating platform is formed between the third space and the second space. The mixer is set in the first space, and the hydraulic pump station is set in the second space.
[0008] In this way, an integrated frame-type equipment can be formed, which can be easily loaded onto a vehicle and transported to the construction site, or it can work directly on the vehicle to reduce on-site operation time, thus conveniently achieving compact miniaturization.
[0009] Preferably, the mixer includes a mixer housing and a mixing mechanism disposed within the mixer housing. Preferably, the mixer is a vertical shaft planetary mixer.
[0010] Preferably, the frame is a rectangular frame, including a bottom frame element, a top frame element, and a support frame element supported between the bottom frame element and the top frame element. Preferably, the mixer includes a feed hopper. Preferably, the top frame element is higher than the operating platform and surrounds a third space. The top frame element is higher than the operating platform by a predetermined distance and surrounds the third space. Because the top frame element surrounds the third space, it provides protection for the operator on the operating platform.
[0011] Preferably, the operating platform extends into the first space to form an auxiliary platform. This allows the operator to access the auxiliary platform from the operating platform, making operation more convenient. Preferably, the auxiliary platform and the operating platform are located on adjacent sides of the feed hopper. Preferably, the auxiliary platform is flush with or higher than the operating platform. Preferably, the auxiliary platform and the operating platform are located on adjacent sides of the feed hopper, so that the feed hopper is located at the corner between the auxiliary platform and the operating platform, making it easier for the operator to operate.
[0012] In addition, since the operating platform is located above the second space (power compartment), forming a three-dimensional space, the platform's base plate also serves as the power compartment's ceiling. This protects the power compartment equipment while also acting as a working and walking platform, which greatly improves the space utilization of the equipment, reduces the overall height, and increases safety.
[0013] One end of the frame along the longitudinal direction is the front end, and the other end is the rear end. The part of the frame corresponding to the front end is the front part, and the part corresponding to the rear end is the rear part. The first frame part is the rear part of the frame (which has a first space), and the second frame part is the front part of the frame (which has a second space and a third space).
[0014] Preferably, the top frame element is provided with lifting lugs.
[0015] Preferably, the frame-type ultra-high performance concrete on-site mixing equipment further includes a first diesel engine. Preferably, the hydraulic system includes a hydraulic oil tank, a hydraulic pump station connected to the hydraulic oil tank, and a mixing motor connected to the hydraulic pump station. The hydraulic pump station includes a hydraulic pump, and the mixing motor is driven by a mixer. Preferably, the hydraulic pump is connected to and driven by the first diesel engine via a transmission device, and the hydraulic pump is connected to the mixing motor via hydraulic lines.
[0016] Preferably, the water supply system includes a main water tank and / or a weighing water tank. Preferably, the water supply system further includes a first water pump connected between the weighing water tank and the mixer. Preferably, the water supply system further includes a second water pump connected between the main water tank and the weighing water tank.
[0017] The first diesel engine, hydraulic oil tank, hydraulic pump station, main water tank and / or weighing water tank are located in the second space.
[0018] Because the equipment is self-powered (first diesel engine), it can operate without external power input, greatly improving operational flexibility. The first diesel engine, hydraulic oil tank, hydraulic pump station, main water tank and / or weighing water tank are located in a second space below the operating platform, which further ensures a low center of gravity for stable operation and provides operators with ample space to move around on the operating platform.
[0019] Preferably, the second space of the frame includes a rear compartment area of the second space near the first space (i.e., near the mixer) and a front compartment area of the second space away from the first space (i.e., away from the mixer). Preferably, the first diesel engine, a radiator for cooling the first diesel engine, a diesel tank for supplying fuel to the first diesel engine 52, a hydraulic oil tank and / or a hydraulic pump of the hydraulic system are located in the front compartment area of the second space.
[0020] Preferably, the frame-type ultra-high performance concrete on-site mixing equipment includes a control box, in which some or all of the operating elements for controlling the on-site concrete mixing operation are housed. The control box is located in the rear compartment of the second space. Because the operating elements are housed primarily within the control box, which is situated in the second space below the operating platform, it facilitates operation of the control box by ground personnel.
[0021] Preferably, the frame includes an entrance passage leading from the second space to the third space, and a working ladder located within the entrance passage (including one side of the entrance passage). Preferably, the frame has an operating door for entering the entrance passage at a position corresponding to the entrance passage. The operating platform has a platform opening at a position corresponding to the entrance passage. Preferably, a platform opening guardrail surrounds the platform opening. Preferably, the working ladder is located on the side of the platform opening away from the first space. Preferably, the opening side of the platform opening guardrail corresponds to the side of the platform opening away from the first space (i.e., away from the mixer).
[0022] By installing guardrails at platform openings, operators can be prevented from accidentally falling into the passageway through the platform openings. In particular, because the opening side of the guardrail is away from the mixer, it ensures that operators are protected by the guardrail when retreating while operating around the mixer (e.g., feeding around the feed hopper), avoiding the risk of falling into the passageway through the guardrail opening.
[0023] Preferably, the sides of the frame are at least partially provided with enclosure panels, which at least partially surround the third space. By providing enclosure panels on the sides of the frame, the entire integrated frame forms a container-like structure, thereby facilitating equipment transportation and ensuring equipment operational safety.
[0024] Preferably, the water supply system further includes a main water tank and a first water pump. The first water pump is configured to be selectively in a first connection state or a second connection state. In the first connection state, the inlet of the first water pump is connected to an external water source, and the outlet is connected to the main water tank or a weighing water tank. In the second connection state, the inlet of the first water pump is connected to the main water tank, and the outlet is connected to the weighing water tank.
[0025] Because of the main water tank and the first water pump that supplies water from the main water tank to the weighing water tank, the entire water preparation equipment can operate even without an external water source. By configuring the connection of the first water pump, water can also be pumped from an external water source to the main water tank or the weighing water tank. For example, the inlet of the first water pump can be connected to an external water source or to the main water tank. When the inlet is connected to an external water source, the outlet can be connected to the main water tank or the weighing water tank, thus supplying water to either tank. With the inlet of the first water pump connected to the main water tank and the outlet connected to the weighing water tank, water can be conveniently supplied from the main water tank to the weighing water tank.
[0026] Preferably, the mixer includes a mixer housing. Preferably, the water supply system includes a weighing water tank and a second water pump, the second water pump being connected between the weighing water tank and the mixer housing. The inclusion of a second water pump allows for rapid water supply as needed, resulting in higher efficiency. It also allows the weighing water tank to be positioned at a lower location, thereby reducing the overall height and center of gravity of the mixing equipment.
[0027] An ultra-high performance concrete on-site mixing equipment is characterized in that the ultra-high performance concrete on-site mixing equipment includes a first diesel engine, a hydraulic system, a water supply system and a mixer, wherein the hydraulic system includes a hydraulic pump station and a mixing motor, the hydraulic pump station includes a hydraulic pump, the mixing motor is driven and connected to the mixer; the hydraulic pump is connected to the first diesel engine and driven by the first diesel engine, and the hydraulic pump is connected to the mixing motor through a pipeline.
[0028] Thus, the equipment achieves a compact and miniaturized design by combining a diesel engine and a hydraulic motor, and requires no external power, making it adaptable to different working environments.
[0029] A vehicle-mounted ultra-high performance concrete mixing system is characterized by comprising: a vehicle having a chassis; and a frame-type ultra-high performance concrete on-site mixing equipment as described in any one of the preceding claims, mounted on the chassis. This vehicle-mounted ultra-high performance concrete mixing system allows for convenient loading and transportation of the mixing equipment to the construction site via a vehicle, and also enables direct operation from the vehicle, reducing on-site work time.
[0030] Preferably, the vehicle is a truck-mounted crane transport vehicle, which has a driver's cab mounted at the front of the chassis and a crane located behind the driver's cab; and a frame-type ultra-high performance concrete on-site mixing equipment is mounted at the rear of the chassis, with the front end of the frame-type ultra-high performance concrete on-site mixing equipment facing the driver's cab and crane of the truck-mounted crane transport vehicle. The truck-mounted crane transport vehicle simultaneously serves as a transport vehicle, outriggers, and a loading crane, greatly improving the convenience of concrete mixing and batching operations. The truck-mounted crane transport vehicle 9 also has outriggers 93, which further improves the stability of the equipment during operation.
[0031] An automated, mobile, compact, ultra-high performance concrete on-site mixing equipment includes a frame, a mixer, a hydraulic pump station, a first diesel engine, a weighing water tank, a metering pump, and a weighing meter. The mixer, hydraulic pump station, first diesel engine, weighing water tank, metering pump, and weighing meter are all fixedly connected to the frame. The equipment integrates the mixer and necessary supporting equipment, including a power unit. This power unit utilizes the first diesel engine instead of an external power source, eliminating dependence on external power and avoiding stalling caused by sudden drops in grid voltage. The frame supports all supporting equipment. The mixer mixes various ingredients evenly. The hydraulic pump station includes a hydraulic pump, to which the first diesel engine provides mechanical power. The hydraulic pump converts this mechanical power into the pressure potential energy of the hydraulic oil. The mixer includes a mixing motor, to which the hydraulic pump station provides hydraulic oil with pressure potential energy, driving the mixing motor to rotate.
[0032] It also includes a control box, diesel tank, hydraulic oil tank, main water tank, battery and / or water pump; the control box, diesel tank, hydraulic oil tank, main water tank, battery and / or water pump are fixedly connected to the frame; the working buttons or hydraulic valves of each device can be directly installed on the device in a convenient operating position, or they can be centrally installed on the control box, which facilitates maintenance and management; various control electrical appliances, such as PLCs, various contactors, and various relays, can be centrally installed in the control box for convenient maintenance and management, and also to protect them from wind, rain and sun; the first diesel engine can have its own diesel tank, or if it does not have one, a relatively large diesel tank can be configured, so the diesel tank's shape design is more flexible and adaptable to the existing space design. The hydraulic pump station can have its own hydraulic oil tank or a separate hydraulic oil tank. The water in the main water tank is used as one of the ingredients and is used before metering. This equipment can be equipped with or without a main water tank. Water can also be supplied on-site using other separate water buckets. Equipping the main water tank makes it more convenient to use. The inlet pump pumps the metered water into the mixer. If the inlet pump is not used, the weighing water tank can be placed at a high position and water can be supplied by gravity potential energy. Equipping the inlet pump makes it easier to control and can supply water quickly as needed, resulting in higher efficiency. The weighing water tank can also be placed at a low position. The battery can power the starter motor, which drives the first diesel engine to start. If there is no battery, the first diesel engine can also be started manually by using a crank handle. Equipping the battery can save manpower.
[0033] The first diesel engine and the hydraulic pump are connected by a transmission device, which refers to a device that can transmit power between two shafts, such as a gear transmission device, chain transmission device, belt transmission device, or coupling. The hydraulic pump draws hydraulic oil from the hydraulic oil tank through pipelines and pumps it to the mixing motor, which drives the mixer to operate. The first diesel engine and the diesel tank are connected by pipelines.
[0034] The mixer includes a mixer housing; a main water tank and a weighing water tank are connected by a first water pipe, on which a metering pump is installed; the weighing water tank and the mixer housing are connected by a second water pipe, on which an inlet pump is installed; the metering pump pumps water from the main water tank to the weighing water tank through the first water pipe, and a weighing scale measures the weight of the weighing water tank until the required weight is reached, at which point the metering pump stops; the inlet pump pumps water from the weighing water tank to the mixer housing through the second water pipe.
[0035] As mentioned above, only one weighing meter is configured. If the weighing meter makes a mistake, it will lead to an incorrect water ratio in the concrete, resulting in unusable concrete. To avoid this error, two weighing meters can be configured to weigh the water tank separately. The two weighing results are compared, and if the difference is too large, an error alarm is issued. For example, a 3% limit can be set, and the larger value cannot be more than 3% larger than the smaller value. Otherwise, an error alarm will be issued. Errors can be detected before the ingredients are mixed, thus preventing errors from occurring, correcting the mixing ratio error in time, and avoiding waste.
[0036] Preferably, the frame has a cuboid outer contour, and its external dimensions, limit deviations and total mass conform to the external dimensions, limit deviations and rated mass of various container models in GB1413-2008, which is suitable for configuring handling vehicles and overall lifting and handling.
[0037] The aforementioned framework is equipped with an operating platform. Operators stand on the operating platform, which is equipped with a control box. The platform drives the feed hopper of the mixer to approach the operating platform, making it more convenient for workers to operate while standing on the platform during feeding.
[0038] This embodiment is placed on a truck for transport. When in use, a crane can be used to lift this embodiment off the truck, or it can be placed on the truck without being lifted off and can work.
[0039] The aforementioned equipment is highly dependent on lifting equipment; the crane must follow the equipment to each construction site, which is inconvenient. Alternatively, a steering wheel and drive wheels can be installed at the bottom of the equipment, allowing it to move automatically. The specific solution is as follows:
[0040] An automated, self-propelled, compact, ultra-high-performance concrete on-site preparation equipment includes a frame, a mixer, a control box, a hydraulic pump station, a first diesel engine, a diesel tank, a hydraulic oil tank, a main water tank, a weighing water tank, a metering pump, a weighing scale, and an inlet pump. The mixer, control box, hydraulic pump station, first diesel engine, diesel tank, hydraulic oil tank, main water tank, weighing water tank, metering pump, weighing scale, and inlet pump are all fixedly connected to the frame. The hydraulic pump station includes a hydraulic pump. The first diesel engine and the hydraulic pump are connected via a transmission device. The hydraulic pump and the mixing motor are connected via pipelines. The frame includes two steering wheels, two drive wheels, and a second diesel engine. The steering wheels and drive wheels are respectively connected to the frame via rotating joints. The drive wheels and the second diesel engine are connected via a transmission system. Relying on the driving force of the second diesel engine, the invention moves along the ground via the two steering wheels and two drive wheels. Thus, the transport of this invention no longer depends on lifting equipment; it automatically travels to the construction site wherever needed, making it more convenient to use.
[0041] The above-described equipment is equipped with two diesel engines, which results in redundant configuration of two components with the same function, leading to waste. Alternatively, only one diesel engine can be configured, as detailed below:
[0042] An automated, self-propelled, compact, ultra-high performance concrete on-site preparation equipment includes a frame, a mixer, a control box, a hydraulic pump station, a first diesel engine, a diesel tank, a hydraulic oil tank, a main water tank, a weighing water tank, a metering pump, a weighing scale, and an inlet pump. The mixer, control box, hydraulic pump station, first diesel engine, diesel tank, hydraulic oil tank, main water tank, weighing water tank, metering pump, weighing scale, and inlet pump are all fixedly connected to the frame. The hydraulic pump station includes a hydraulic pump. The first diesel engine and the hydraulic pump are connected via a transmission device. The hydraulic pump and the mixing motor are connected via pipelines. The frame includes two steering wheels and two drive wheels. The steering wheels and drive wheels are respectively connected to the frame via rotating joints. The drive wheels and the first diesel engine are connected via a transmission system. Relying on the driving force of the first diesel engine, the invention moves along the ground via the two steering wheels and two drive wheels. The drive wheels and hydraulic pumps often do not work simultaneously. When moving, the hydraulic pump is idle, and the mixing plant and supporting equipment are also idle. When the mixing plant and supporting equipment are working, the invention is often stationary on the ground and does not move. Therefore, the two functions can use the same first diesel engine, saving one diesel engine, reducing the cost of the equipment, and reducing the weight of the equipment.
[0043] The automated, self-propelled, compact, ultra-high-performance concrete on-site mixing equipment described above is relatively easy to move on flat ground. However, some construction sites have soft, uneven, or muddy ground, which can prevent the steering wheel and drive wheel from functioning properly. Replacing the steering wheel and drive wheel with a combination of tracked wheels and tracks can effectively solve this problem. The specific solution is as follows:
[0044] An automated, self-propelled, compact, ultra-high-performance concrete on-site preparation equipment includes a frame, a mixer, a hydraulic pump station, a first diesel engine, a weighing water tank, a metering pump, and a weighing scale. The mixer, hydraulic pump station, first diesel engine, weighing water tank, metering pump, and weighing scale are all fixedly connected to the frame. The hydraulic pump station includes a hydraulic pump. The first diesel engine and the hydraulic pump are connected via a transmission device. The hydraulic pump and the mixing motor are connected via pipelines. The frame includes four track wheels, two tracks, and two track motors. The four track wheels are connected to the frame via rotating pairs. One track is tensioned and wrapped around two track wheels. The hydraulic pump and the track motors are connected via hydraulic pipelines. The hydraulic pump drives the track motors to rotate using hydraulic oil with pressure potential energy. The track motors drive the equipment to move via the tracks. Compared to technical solutions using steering wheels and drive wheels, this solution is suitable for working on soft, uneven, or muddy ground.
[0045] The beneficial effects of this invention are as follows: This invention features a specially integrated, miniaturized, containerized, and independent design. One device integrates all the functions required for mixing operations, does not rely on external power sources, is easy to transport or self-propelled, can be transported by a single vehicle, or can move on its own without the need for other vehicles. Pipelines and wires are assembled in the processing plant and do not need to be disassembled during transport, saving a lot of time on disassembly, installation, and debugging, and greatly improving production efficiency.

[0062] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0063] Example 1: An automated, mobile, compact, ultra-high performance concrete on-site mixing equipment, such as... Figure 1-2 As shown, this equipment is a frame-type ultra-high performance concrete on-site mixing equipment, including a frame 1, a mixer 2, a hydraulic pump station 51, a first diesel engine 52, a weighing water tank 8, a metering pump (the first water pump, whose function is to pump water into the weighing water tank for weighing and measurement, does not need to have a metering function itself) and a weighing meter; the mixer 2, hydraulic pump station 51, first diesel engine 52, weighing water tank 8, metering pump, and weighing meter are all fixedly connected to the frame 1. That is, the equipment integrates the mixer and necessary supporting equipment, including the power equipment. The power equipment does not use an external power source, but uses the first diesel engine, eliminating dependence on an external power source and avoiding stalling caused by a sudden drop in grid voltage. Preferably, the frame 1 is an integrated frame, which supports all supporting equipment, and the mixer 2 is used to mix various ingredients evenly. The hydraulic pump station 51 includes a hydraulic pump. A first diesel engine 52 provides mechanical power to the hydraulic pump, which converts the mechanical power into the pressure potential energy of the hydraulic oil. The mixer 2 includes a mixing motor 24. The hydraulic pump station 51 provides hydraulic oil with pressure potential energy to the mixing motor 24, driving the mixing motor 24 to rotate. The hydraulic pump station 51 and the hydraulic motor are at least part of the hydraulic system. The weighing water tank 8, the metering pump, and the weighing meter are at least part of the water supply system.
[0064] This ultra-high performance concrete on-site mixing equipment also includes a control box 3, a control box 4, a diesel tank 53, a hydraulic oil tank 54, a main water tank 6, a battery 7, and / or a water pump. The operating buttons or hydraulic valves of each device can be directly installed on the equipment in convenient locations, or they can be centrally installed on the control box 3 for easier maintenance and management. Various control electrical components, such as PLCs, contactors, and relays, can be centrally installed in the control box 4 for easy maintenance and management, and to protect them from wind, rain, and sun. The first diesel engine 52 can have its own diesel tank; if not, a larger diesel tank 53 can be configured, allowing for flexible design of the diesel tank 53 to fit within available space. The hydraulic pump station 51 can have its own hydraulic oil tank, or a separate hydraulic oil tank 54 can be configured. The water in the main water tank 6 is used as one of the ingredients and is used before metering. This equipment can be equipped with or without a separate water tank on-site; water can also be supplied using other separate water buckets. The inclusion of the main water tank 6 makes operation more convenient. The water inlet pump (the second water pump, whose function is to pump water from the weighing water tank into the mixer) pumps the metered water into the mixer. If the water inlet pump is not used, the weighing water tank 8 can be placed at a high position and water can be supplied by gravity potential energy. The water inlet pump makes it easier to control and can supply water quickly as needed, resulting in higher efficiency. Alternatively, the weighing water tank can be placed at a low position. The battery 7 can supply power to the starter motor, which drives the first diesel engine 52 to start. If the battery 7 is not available, the first diesel engine 52 can also be started manually by using a crank handle.
[0065] The first diesel engine 52 and the hydraulic pump are connected through a transmission device, which refers to a device that can transmit power between two shafts, such as a gear transmission device, chain transmission device, belt transmission device, or coupling. The hydraulic pump draws hydraulic oil from the hydraulic oil tank 54 through a pipeline and pumps it to the stirring motor 24, which drives the mixer 2 to operate. The first diesel engine 52 and the diesel tank 53 are connected through a pipeline.
[0066] The mixer 2 includes a mixer housing 21; the main water tank 6 and the weighing water tank 8 are connected by a first water pipe, and a metering pump is installed on the first water pipe; the weighing water tank 8 and the mixer housing of the mixer 2 are connected by a second water pipe, and an inlet pump is installed on the second water pipe; the metering pump pumps water from the main water tank 6 to the weighing water tank 8 through the first water pipe, and the weighing scale measures the weight of the weighing water tank 8 until the required weight is reached, after which the metering pump stops; the inlet pump pumps water from the weighing water tank 8 to the mixer housing 21 through the second water pipe.
[0067] As mentioned above, only one weighing meter is configured. If the weighing meter makes a mistake, it will lead to an incorrect water ratio in the concrete, resulting in the concrete being unusable. To avoid this error, two weighing meters can be configured to weigh the water tank 8 separately. The two results are compared, and if the difference is too large, an error alarm is issued. For example, a 3% limit can be set, meaning the larger value cannot be more than 3% larger than the smaller value; otherwise, an error alarm will be issued. Errors are detected before batching, thus preventing them from occurring, correcting the ratio error in time, and avoiding waste.
[0068] Frame 1 has a rectangular outer contour, and its external dimensions, limit deviations and total mass conform to the external dimensions, limit deviations and rated mass of various container models in GB1413-2008, which makes it suitable for configuring handling vehicles and overall lifting and handling.
[0069] The frame 1 described above is equipped with an operating platform 11. The operator stands on the operating platform 11. The control box 3 is set on the operating platform 11 to drive the feed hopper 23 of the mixer 2 to approach the operating platform 11. It is more convenient for the worker to operate while standing on the operating platform 11 when feeding materials.
[0070] The frame 1 described above is equipped with a lifting lug 13 at its top, which allows for easy lifting by a crane.
[0071] In this embodiment, the hydraulic system, water supply system, and mixer 21 are all mounted on the integrated frame 1. Figure 1-2 As can be seen, frame 1 includes a first frame section (front of the frame) and a second frame section (rear of the frame) arranged along the longitudinal direction of the frame. A first space S1 is formed within the first frame section, and a second space S2 and a third space S3 are formed within the second frame section. The third space S3 is located above the second space S2, and the operating platform 11 is formed between the third space S3 and the second space S2. The mixer 2 is located in the first space S1, and the hydraulic pump station 51 is located in the second space S2. Because the operating platform 11 is located above the second space (power compartment), forming a three-dimensional space, and the platform's base plate also serves as the ceiling of the power compartment, protecting the equipment in the power compartment while also serving as a working and walking platform, this greatly improves the space utilization of the equipment, reduces the overall height, and increases safety.
[0072] In this embodiment, frame 1 is a rectangular frame, including a bottom frame element F1, a top frame element F2, and a support frame element F3 supported between the bottom frame element F1 and the top frame element F2. One end of frame 1 along the longitudinal direction of the frame is the front end, and the other end is the rear end. The part of frame 1 corresponding to the front end is the front part, and the part corresponding to the rear end is the rear part. The first frame part is the rear part of the frame (which has a first space S1), and the second frame part is the front part of the frame (which has a second space S2 and a third space S3).
[0073] Preferably, the mixer 2 includes a feed hopper 23. Preferably, the top frame element F2 is higher than the operating platform and surrounds the third space S3. The top frame element F2 is higher than the operating platform by a predetermined distance and surrounds the third space S3. The top frame element F3 surrounds the third space S3, thereby protecting the operator on the operating platform 11.
[0074] Because of its integrated frame, this frame-type equipment can be easily loaded onto a vehicle and transported to the construction site, or it can work directly on the vehicle.
[0075] This embodiment is placed on a truck for transport. When in use, a crane can be used to lift this embodiment off the truck, or it can be placed on the truck without being lifted off, thereby reducing on-site operation time.
[0076] Preferably, the frame-type ultra-high performance concrete on-site preparation equipment also includes a first diesel engine 52. The hydraulic system includes a hydraulic oil tank 54, a hydraulic pump station 51 connected to the hydraulic oil tank 54, and a mixing motor 24 connected to the hydraulic pump station 51. The hydraulic pump station 51 includes a hydraulic pump, and the mixing motor 24 is drivenly connected to the mixer 21.
[0077] Preferably, the hydraulic pump is connected to and driven by the first diesel engine 52 via a transmission device, and is connected to the mixing motor 24 via a hydraulic pipeline. The water supply system includes a main water tank 6, a weighing water tank 8, a first water pump connected to the main water tank 6 and / or the weighing water tank 8, and a second water pump connected between the weighing water tank 8 and the mixer 2. The first diesel engine 52, hydraulic oil tank 54, hydraulic pump station 51, main water tank 6 and / or weighing water tank 8 are arranged in the second space S2. Since the preparation equipment is self-powered (first diesel engine 52), it can operate without external power input, greatly improving operational flexibility. The arrangement of the first diesel engine 52, hydraulic oil tank 54, hydraulic pump station 51, main water tank 6 and weighing water tank 8 and / or within the second space S2 ensures that the entire equipment has a low center of gravity for stable operation and provides operators with ample space for movement on the operating platform.
[0078] Preferably, in this embodiment, the second space S2 includes a rear compartment S21 of the second space close to the first space S1 and a front compartment S22 of the second space away from the first space S1; the first diesel engine 52, a radiator for cooling the first diesel engine 52, a diesel tank 53 for supplying oil to the first diesel engine 52, a hydraulic oil tank of the hydraulic system and a hydraulic pump station 51 are arranged in the front compartment S21 of the second space.
[0079] Preferably, in this embodiment, the water supply system includes a main water tank 6 and a first water pump. The first water pump is configured to selectively be in a first connection state or a second connection state. In the first connection state, the inlet of the first water pump is connected to an external water source, and the outlet is connected to the main water tank 6 or the weighing water tank 8. In the second connection state, the inlet of the first water pump is connected to the main water tank 6, and the outlet is connected to the weighing water tank 8. Because of the main water tank and the first water pump that pumps water from the main water tank to the weighing water tank, the entire water preparation equipment can operate even without an external water source. By configuring the connection state of the first water pump, water can also be pumped from an external water source to the main water tank 6 or the weighing water tank 8. For example, the inlet of the first water pump can be connected to an external water source or to the main water tank 6. When the inlet is connected to an external water source, the outlet can be connected to the main water tank 6 or the weighing water tank 8, thereby supplying water to the main water tank 6 or the weighing water tank 8. The inlet of the first water pump is connected to the main water tank, and the outlet is connected to the weighing water tank, so that water can be conveniently supplied to the weighing water tank.
[0080] Preferably, in this embodiment, the mixer 2 includes a mixer housing 21. The water supply system includes a weighing water tank 8 and a second water pump, which is connected between the weighing water tank 8 and the mixer housing 21. The inclusion of a second water pump makes control easier, allows for rapid water supply as needed, improves efficiency, and allows the weighing water tank to be positioned at a lower location, thereby reducing the overall height and center of gravity of the mixing equipment.
[0081] Example 2: An automated, self-propelled, compact, ultra-high performance concrete on-site mixing equipment, such as... Figure 3-4As shown, the system includes a frame 1, a mixer 2, a hydraulic pump station 51, a first diesel engine 52, a weighing water tank 8, a metering pump, and a weighing scale. The mixer 2, hydraulic pump station 51, first diesel engine 52, weighing water tank 8, metering pump, and weighing scale are all fixedly connected to the frame 1. The hydraulic pump station 51 includes a hydraulic pump. The first diesel engine 52 and the hydraulic pump are connected via a transmission device. The hydraulic pump and the mixing motor 24 are connected via pipelines. The frame 1 includes two steering wheels 14, two drive wheels 15, and a second diesel engine. The steering wheels 14 and drive wheels 15 are connected to the frame 1 via rotating pairs. The drive wheels 15 and the second diesel engine are connected via a transmission system. Relying on the driving force of the second diesel engine, this embodiment moves along the ground via the two steering wheels 14 and the two drive wheels 1. Thus, the handling in this embodiment no longer relies on lifting equipment; it automatically moves to the construction site wherever needed, making it more convenient to use. The transmission system refers to devices such as gear drives, chain drives, belt drives, and couplings that can transmit power between two shafts.
[0082] Other unmentioned structures, functions, and effects of use are the same as in Example 1.
[0083] Example 3: An automated, self-propelled, compact, ultra-high performance concrete on-site mixing equipment, such as... Figure 3-4 As shown, the system includes a frame 1, a mixer 2, a hydraulic pump station 51, a first diesel engine 52, a weighing water tank 8, a metering pump, and a weighing scale. The mixer 2, hydraulic pump station 51, first diesel engine 52, weighing water tank 8, metering pump, and weighing scale are fixedly connected to the frame 1. The hydraulic pump station 51 includes a hydraulic pump. The first diesel engine 52 and the hydraulic pump are connected through a transmission device. The hydraulic pump and the mixing motor 24 are connected through pipelines. The frame 1 includes two steering wheels 14 and two drive wheels 15. The steering wheels 14 and the drive wheels 15 are respectively connected to the frame 1 through a rotating joint. The drive wheels 15 and the first diesel engine 52 are connected through a transmission system. Relying on the driving force of the first diesel engine 52, this embodiment moves along the ground through the two steering wheels 14 and the two drive wheels 1. The drive wheel 15 and the hydraulic pump often do not work simultaneously. When moving, the hydraulic pump is idle, and the mixing plant and supporting equipment are also idle. When the mixing plant and supporting equipment are working, this embodiment is often stationary on the ground and does not move. Therefore, the two functions can use the same first diesel engine 52, which saves one diesel engine compared to embodiment 2, reduces the cost of the equipment, and reduces the weight of the equipment.
[0084] The transmission system may also include a first clutch, and the transmission device may also include a second clutch, so that the hydraulic pump can be disconnected or engaged with the first diesel engine 52 through the second clutch, and the drive wheel 15 can be disconnected or engaged with the first diesel engine 52 through the first clutch. When traveling, the first clutch is engaged and the second clutch is disengaged, and when stirring, the second clutch is engaged and the first clutch is disengaged.
[0085] Other unmentioned structures, functions, and effects of use are the same as in Example 1.

Figure 5-6 As shown, the system includes a frame 1, a mixer 2, a hydraulic pump station 51, a first diesel engine 52, a weighing water tank 8, a metering pump, and a weighing scale. The mixer 2, hydraulic pump station 51, first diesel engine 52, weighing water tank 8, metering pump, and weighing scale are all fixedly connected to the frame 1. The hydraulic pump station 51 includes a hydraulic pump. The first diesel engine 52 and the hydraulic pump are connected via a transmission device. The hydraulic pump and the mixing motor 24 are connected via pipelines. The frame 1 includes four track wheels 16, two tracks 17, and two track motors. The four track wheels 16 are respectively connected to the frame 1 via rotating pairs. One track 17 is tightly wound around two track wheels 16. The hydraulic pump and the track motors are connected via hydraulic pipelines. The hydraulic pump drives the track motors to rotate, and the track motors drive the equipment to move via the tracks 17. Compared to embodiment 3, this embodiment is suitable for working on soft, uneven, or muddy ground.
[0087] Other unmentioned structures, functions, and effects of use are the same as in Example 1.
[0088] Example 5: An ultra-high performance concrete on-site mixing equipment, such as... Figure 7-8 As shown, the ultra-high performance concrete on-site mixing equipment is a frame-type ultra-high performance concrete on-site mixing equipment.
[0089] In this embodiment, the second space S2 of the frame 1 includes a rear compartment S21 near the first space S1 and a front compartment S22 away from the first space S1. The frame-type ultra-high performance concrete on-site mixing equipment includes a control box 3, in which some or all of the operating elements for controlling the on-site concrete mixing operation are located.

Preferably, a platform opening and a platform opening guardrail 19 surrounding the platform opening are located on the operating platform 11 corresponding to the position of the entrance passage. The working ladder 18 is located on the side of the platform opening away from the first space S1, and the opening side of the platform opening guardrail 19 corresponds to the side of the platform opening away from the first space S1. The platform opening guardrail 19 prevents operators from accidentally falling into the passage through the platform opening.
[0091] from Figure 7-8 As can be seen, the sides of frame 1 are at least partially provided with enclosure panels 1a, which at least partially surround the third space S3. By providing enclosure panels 1a on the sides of the frame, the entire integrated frame forms a container-like structure, thereby facilitating equipment transportation and ensuring equipment operation safety.
[0092] Other unmentioned structures, functions, and effects of use are the same as in Example 1.
[0093] Example 6: See Figure 9 A vehicle-mounted mixing system includes: a vehicle having a chassis; and an ultra-high performance concrete on-site mixing equipment as described in any of the foregoing embodiments, particularly embodiments 1 and 5, wherein the ultra-high performance concrete on-site mixing equipment is mounted on the chassis.
