Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint delivery pump technology, and in particular to a portable fireproof paint delivery pump. Background Technology
[0002] Fire-retardant coatings can improve the fire resistance of building surfaces. Applying a layer of coating acts as a fire-resistant and heat-insulating layer, preventing high-temperature deformation and collapse of buildings. This provides more time for firefighters and rescuers to transport personnel and materials. In particular, steel structure factory columns require fire safety protection, and relevant regulations mandate the application of thick fire-retardant coatings.
[0003] Fire-retardant coating application in common steel structure workshops can be roughly divided into three work areas: 1. a centralized storage area for bagged fire-retardant coatings; 2. a mixing area for water, electricity, and mixers; and 3. a work area for on-site spraying machines. The distance between the mixing area and the spraying area is usually quite far. Currently, the conventional practice is to manually load the mixed coating into small buckets, then transport the buckets to vehicles, and then to the vicinity of the spraying machine. Finally, workers pour the coating from the buckets into the spraying equipment's hopper. This multiple handling and transfer process is labor-intensive for workers, with each person handling approximately tens of tons of material per day. This high-intensity labor leads to difficulties in recruiting workers, a lack of specialized conveying equipment, small transport volumes per trip, and high transport frequency, resulting in low work efficiency and high construction costs. In summary, the lack of modern automated conveying equipment is a major problem. Utility Model Content
[0004] The purpose of this invention is to solve the problems of small single-transport volume and high frequency of traditional manual transfer, which seriously affect the construction progress. In this solution, the pump body hopper can hold more paint. Combined with the flexible mobility of the electric mobile vehicle, it can transfer a sufficient amount of paint from the mixing area to the spraying area in one go, reducing the frequency of transportation. At the same time, the pump body directly delivers the paint to the spraying equipment, eliminating the need for handling the loading and unloading of barrels. Powder can also be poured directly into the hopper of the delivery pump, mixed with water using an electric drill, and then directly pumped to the transfer barrel on the vehicle or the hopper of the spraying machine. This reduces the number of times the fireproof paint is handled, greatly reducing the labor intensity of construction and improving construction efficiency. The delivery pump is designed with a reverse mixing function, which can continuously and repeatedly mix the paint, making it more convenient and flexible to use and improving the overall transportation and delivery efficiency.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A portable fire-retardant coating delivery pump includes an electric mobile vehicle. A pump body hopper is movably connected to the upper rear of the electric mobile vehicle. A filter screen safety protection structure is provided on the upper end of the pump body hopper. A delivery pump is diagonally inserted into the pump body hopper. The output end of the delivery pump is provided with a discharge port. The electric mobile vehicle includes a support frame. An L-shaped tubular fixing frame is fixedly connected to the support frame. Hopper limiting plates are provided on both sides of the bottom end of the L-shaped tubular fixing frame. Hopper locks are provided on both sides of the upper corner end of the L-shaped tubular fixing frame for locking the pump body hopper to fix or release it. A limit is provided on one side of the upper corner end of the L-shaped tubular fixing frame. A steel wire is used to limit the tilting of the pump body hopper. The L-shaped tubular fixing frame has a bushing at its tail, and the other end of the bushing is fixedly connected to the bottom of the pump body hopper. The pump body hopper can be tilted at an angle using the bushing as a fulcrum. The overall design realizes the mobility of the equipment, allowing it to be flexibly transferred in different construction scenarios, solving the problem of traditional equipment handling. The tilting structure of the pump body hopper provides convenience for subsequent cleaning and maintenance. The filter screen safety protection structure can filter impurities, protect the pump body, and improve the safety and service life of the equipment. The double fixing structure ensures the stability of the equipment during movement or operation, reducing the risk of shaking or falling off.
[0007] Furthermore, a motor drive device is fixedly connected to the bottom of the support frame, and rear wheels are provided on both sides of the motor drive device. A battery device is provided on one side of the upper end of the support frame, and a front wheel is provided at the front end of the support frame. A control device is provided at the upper front end of the support frame, and a light is provided at the lower end of the control device. A handle is provided on one side of the upper end of the L-shaped tubular fixing frame, located below the truck bed lock, for controlling the switch of the delivery pump. The electric drive movement eliminates the need for manual handling, reducing labor costs and improving movement efficiency. The front wheels enhance the equipment's steering flexibility, allowing for easy adjustment of direction even in narrow or complex environments. The control device simplifies operation, and the light provides illumination in low-light environments, improving construction adaptability and safety. The battery device eliminates dependence on external power sources, expanding the equipment's applicability.
[0008] Furthermore, the pump body hopper includes a hopper, with hopper fixing lugs on both sides of the bottom for assembly and connection with the hopper limiting plate. Locks are provided on both sides of the front end of the hopper for assembly and connection with the vehicle lock. Steel wire connectors are fixedly installed between the locks and the hopper, and are fixedly connected to the limiting pull wire. A discharge port is provided at the top of the hopper. The connection structure between the pump body hopper and the mobile vehicle enables quick assembly and disassembly and a stable connection, facilitating equipment assembly, maintenance, and repair. The cooperation between the steel wire connectors and the limiting pull wire provides controllable limits for tilting, avoiding equipment damage and operational hazards, improving safety. The compact structural design reduces the overall size of the equipment and also helps improve paint conveying efficiency.
[0009] Furthermore, the pump body hopper has two forms: a flat state and a flipped state. These two forms meet the needs of different scenarios. The flat state ensures the continuity of construction, while the flipped state facilitates cleaning, inspection, and maintenance of the hopper's interior. This solves the cleaning problem of traditional fixed hoppers, extends the service life of the equipment, and reduces maintenance costs.
[0010] Furthermore, when the pump body hopper is in a flipped state, the hopper fixing lugs separate from the hopper limiting plate, the hopper lock is released from the buckle, and the pump body hopper flips around the bushing as the axis. The flipping angle is limited by the cooperation of the limiting pull wire and the wire connector. When the pump body hopper is in a flat state, the hopper fixing lugs are inserted into the hopper limiting plate, the hopper lock is locked and fixed with the buckle, and the limiting pull wire is in a relaxed state.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. By combining existing transportation tools and conveying pumps, efficiency can be improved. The distance between the mixing area and the spraying equipment is usually long and changes depending on the spraying work. Considering the site environment and the fact that the power supply is not mobile, a new vehicle frame with built-in conveyor is designed to achieve this. The overall integrated design can save costs and improve efficiency.
[0013] 2. Large-capacity storage design: The concave bottom design allows the fire-retardant coating to concentrate at the bottom under gravity, making it easier to pump cleanly. Typically, several spraying machines operate simultaneously in the spraying area. To maximize the transport volume and quickly deliver the mixed fire-retardant coating to the spraying machines, the fire-retardant coating hopper volume must be as large as possible. The calculations included determining the amount of coating that multiple spraying machines can spray simultaneously per unit time, and measuring the round-trip time. The time from mixing the fire-retardant coating to spraying it onto the building surface was measured based on factors such as the coating's properties, viscosity, and curing time. Through these measurements and calculations, the optimal hopper volume was determined to be between 250L and 320L.
[0014] 3. The stirring function features a forward and reverse rotation design. Forward rotation outputs the fire retardant coating, while reverse rotation stirs the fire retardant coating. If the fire retardant coating was not sufficiently stirred or there was sedimentation or separation in the previous process, a spiral conveyor method is used to achieve secondary stirring and mixing, improving the viscosity of the fire retardant coating and making subsequent spraying operations smoother.
[0015] 4. The pump body and hopper have a rotatable, flat bottom design, making equipment cleaning simpler and cleaner. The upper part of the pump body and the pump body adopt a modular design, with a quick-release structure between the two, making equipment maintenance and installation simpler.
[0016] 5. The pump body features a simplified design, large pumping flow rate, compact structure, and low maintenance costs. Compared to manual labor, it reduces labor intensity and increases efficiency. Attached Figure Description
