Description

Technical Field

[0001] The present application relates to the technical field of concrete pumping equipment, and in particular to a pump lubrication product transportation equipment for concrete pumping. Background Art

[0002] In the field of construction, ready-mixed concrete pumping technology has been widely used, especially for high-rise and super-high-rise building construction, where its convenience and efficiency are particularly important. In order to ensure the smooth progress of pumping construction, the pump pipe must be moistened and lubricated before pumping concrete to reduce the friction between the concrete and the pump pipe, thereby avoiding possible problems during the pumping process. With the continuous development of the construction industry and technological innovation, the pump lubrication link in pumping construction has become one of the important steps to ensure the quality of the project. Therefore, efficient pump lubrication technology has become the focus of construction parties.

[0003] In order to solve the problem of wetting and lubricating the pump pipe before concrete is pumped, the existing technical means usually use tank trucks to transport pump-wetting mortar or other pump-wetting products to the construction site, and use pump-wetting mortar or other pump-wetting products to wet and lubricate the pump pipe. Although this method meets the construction requirements to a certain extent, with the advancement of pumping technology and higher requirements for efficiency and resource utilization, the conventional method of transporting pump-wetting products by tank trucks has exposed its shortcomings. The main problem is that pump-wetting mortar or other pump-wetting products are easily adsorbed on the tank wall during tank truck transportation. Therefore, in order to ensure that the amount of pump-wetting mortar or other pump-wetting products is sufficient before the concrete is opened, the tank truck's carrying capacity of pump-wetting mortar or other pump-wetting products usually needs to be higher than the actual demand, and the excess pump-wetting mortar or other pump-wetting products produced are wasted, resulting in material waste.

[0016] 2. The present application installs a power take-off device on a transport vehicle.

[0021] The following will be combined with the attached Figure 1 -Attached Figure 6 , the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0022] The inventor of the present application has found that in the process of transporting pump-lubricating mortar or other pump-lubricating products by existing tank trucks, the pump-lubricating mortar or other pump-lubricating products are easily adsorbed on the tank wall. Therefore, in order to ensure that the amount of pump-lubricating mortar or other pump-lubricating products is sufficient before the concrete is opened, the amount of pump-lubricating mortar or other pump-lubricating products carried by the tank truck usually needs to be higher than the actual demand, and the excess pump-lubricating mortar or other pump-lubricating products are wasted, resulting in a waste of materials. To this end, the present application discloses a pump-lubricating product transportation equipment for concrete pumping, which mainly adopts the following scheme: The present application embodiment discloses a pump lubrication product transportation device for concrete pumping. Figure 1 , 2 , including a transport vehicle 1, on which a material storage barrel 2 is fixedly provided, on which a stirring rod 3 is rotatably provided, and on which a power system for driving the stirring rod 3 to rotate is provided, so that the purpose of continuously stirring the wet pump mortar or other wet pump products during transportation and at the construction site is achieved, thereby ensuring that the wet pump mortar or other wet pump products are in the best state at all times, avoiding the stratification and adhesion of the wet pump mortar due to standing still, greatly reducing material waste, and improving construction efficiency.

[0023] Reference Figure 2The storage barrel 2 is cylindrical, and a feed port 21 is provided on the top of the storage barrel 2. The cylindrical storage barrel 2 has a large volume and good stability, and is suitable for long-distance transportation and large-capacity storage. A discharge pipe 22 is connected to the storage barrel 2 near the bottom, and a valve 23 is provided on the discharge pipe 22. The valve 23 is a hand valve, and the discharge speed and amount of the lubricating mortar or other lubricating products can be controlled by adjusting the opening of the valve 23, thereby further improving the convenience and safety of operation.

[0024] Reference Figure 3 The stirring rod 3 is made of high-strength steel, has good wear resistance and corrosion resistance, and can effectively extend the service life. A stirring paddle 31 is fixedly arranged on the stirring rod 3. In the embodiment of the present application, a plurality of stirring paddles 31 are arranged, and are evenly spaced along the circumference of the stirring rod 3. In other application embodiments, the stirring paddle 31 can be a spiral blade stirring paddle, a turbine blade stirring paddle, an anchor stirring paddle, a frame stirring paddle, a propeller stirring paddle, or any other form of stirring paddle.

[0025] Reference Figure 3 The power system includes a hydraulic motor 24 and an oil supply unit. The hydraulic motor 24 is fixedly mounted on the storage barrel 2, and the output shaft of the hydraulic motor 24 is coaxially fixedly connected with the stirring rod 3 to drive the stirring rod 3 to rotate. Specifically, the hydraulic motor 24 can be a single-acting or multi-acting hydraulic motor 24. The single-acting hydraulic motor 24 has a simple structure and low cost, and is suitable for intermittent working scenarios; the multi-acting hydraulic motor 24 has a higher torque output capacity and is suitable for situations where continuous stirring is required.

[0026] Reference Figure 1 , 3 The oil supply unit is used to deliver hydraulic oil to the hydraulic motor 24, and specifically includes an oil pump motor 11, an oil delivery pipe 12, an oil return pipe 13 and a power take-off device 14. The oil pump motor 11 is installed on the transport vehicle 1, and the oil pump motor 11 uses an efficient and energy-saving oil pump motor 11, which can achieve a large flow output under a relatively low power, reduce energy consumption and ensure sufficient oil supply. The power take-off device 14 adopts a power take-off, which is respectively connected to the engine transmission system of the transport vehicle 1 and the input shaft of the oil pump motor 11, and is used to intercept part of the kinetic energy generated by the engine transmission system of the transport vehicle 1, and convert this part of energy into working power of the oil pump motor 11, thereby realizing effective utilization of energy without affecting the normal operation of the vehicle.

[0027] Reference Figure 3A hydraulic reversing valve 25 is fixedly arranged on the storage barrel 2, one end of the oil delivery pipe 12 is connected to the oil outlet of the oil pump motor 11, the other end of the oil delivery pipe 12 is connected to the oil inlet of the hydraulic reversing valve 25, one end of the return oil pipe 13 is connected to the oil outlet of the hydraulic reversing valve 25, the other end of the return oil pipe 13 is connected to the oil inlet of the oil pump motor 11, and a plurality of oil passages 251 are arranged on the hydraulic reversing valve 25, which are respectively connected to the oil inlet and oil outlet of the hydraulic motor 24; when the oil pump motor 11 is started, the hydraulic oil flows to the hydraulic reversing valve 25 through the oil delivery pipe 12, and the hydraulic oil is controlled by the hydraulic reversing valve 25 to enter from the oil inlet of the hydraulic motor 24, and then flows out from the oil outlet of the hydraulic motor 24, thereby driving the hydraulic motor 24 to work and driving the agitator shaft to rotate. The hydraulic oil flowing out of the oil outlet of the hydraulic motor 24 flows back into the hydraulic reversing valve 25, and finally flows back into the oil pump motor 11 through the oil return pipe 13 to circulate.

[0028] Specifically, the oil inlet and oil outlet of the hydraulic motor 24 will be changed according to the adjustment of the hydraulic reversing valve 25. For example, when the hydraulic reversing valve 25 controls the hydraulic oil to enter from the oil inlet of the hydraulic motor 24 and then flow out from the oil outlet of the hydraulic motor 24, the hydraulic motor 24 controls the stirring rod 3 to rotate clockwise. When the hydraulic reversing valve 25 controls the hydraulic oil to enter from the original oil outlet of the hydraulic motor 24 and then flow out from the original oil inlet of the hydraulic motor 24, at this time, the original oil outlet of the hydraulic motor 24 becomes the oil inlet, and the original oil inlet of the hydraulic motor 24 becomes the oil outlet. At this time, the hydraulic motor 24 drives the stirring rod 3 to rotate counterclockwise, so that the rotation direction of the stirring rod 3 can be adjusted as needed to enhance the stirring effect.

[0029] In the real-time example of the present application, the oil pipeline 12 and the oil return pipe 13 are both formed by splicing a number of steel pipes with adapters to ensure the structural strength of the oil pipeline 12 and the oil return pipe 13; in other application embodiments, the oil pipeline 12 and the oil return pipe 13 may also use pressure-resistant hoses or metal bellows, which not only ensure the flexibility of the pipeline but also have a certain rigidity, help to improve the reliability and durability of the oil circuit system, and facilitate the adjustment of the length and direction according to actual conditions.

[0030] Reference Figure 1 The transport vehicle 1 is also equipped with an electric motor 15, which is connected to the oil pump motor 11 and is used to drive the input shaft of the oil pump motor 11 to rotate. By installing the electric motor 15 on the transport vehicle 1, when the transport vehicle 1 arrives at the construction site and parks for construction, the kinetic energy generated by the electric motor 15 drives the oil pump motor 11 to work, ensuring that the mortar or other pump products can be strongly stirred while the transport vehicle 1 arrives at the construction site and parks for construction, thereby ensuring the uniformity and discharge rate of the mortar or other pump products during on-site construction.

[0031] Reference Figure 3 ,4 In order to enhance the stirring effect, the stirring rod 3 is hollow, and the side wall of the stirring rod 3 is provided with an air inlet 32 ​​and a plurality of air outlets 33. The air inlet 32 ​​is provided near the top of the stirring rod 3, and the air outlets 33 are provided near the bottom of the stirring rod 3. The air outlets 33 at the same height are evenly spaced along the circumference of the stirring rod 3, and the air outlets 33 at different heights are evenly spaced along the length direction of the stirring rod 3. An air compressor 26 is fixedly provided on the storage barrel 2, and the air compressor 26 is connected with an air supply component for delivering high-pressure air to the air inlet 32. When the stirring rod 3 is working, by introducing compressed air, the rapid stirring of the stirring rod 3 itself, and the continuous input of high-pressure gas form air convection, so that the wet pump mortar or other wet pump products form a strong airflow during the stirring process, increase the stirring intensity of the wet pump mortar or other wet pump products, and further improve the uniformity of the wet pump mortar or other wet pump products.

[0032] Reference Figure 3 , 5 The air supply assembly includes an air supply pipe 261 and a sealing cover 34. The air supply pipe 261 is connected to the air outlet of the air compressor 26. The sealing cover 34 is rotatably sleeved on the stirring rod 3, and the air inlet 32 ​​is covered in the sealing cover 34. The air supply pipe 261 is connected to the inside of the sealing cover 34. The material of the air supply pipe 261 is stainless steel or nylon. The former is corrosion-resistant and wear-resistant, and the latter is light and flexible. Both materials can meet the requirements of different working conditions. The sealing cover 34 is made of cemented carbide, which has high hardness and wear resistance. It can effectively prevent external impurities from invading the stirring system and protect the stirring rod 3 from damage. The stirring rod 3 and the upper and lower sides of the air inlet 32 ​​are respectively sleeved with airtight bearings 35. The inner ring of the airtight bearing 35 is fixedly connected to the stirring rod 3, and the outer ring of the airtight bearing 35 is fixedly connected to the seal to ensure that the airflow is stable and leak-free during the stirring process, and enhance the consistency of the stirring effect.

[0033] Reference Figure 6 A film 331 is provided at the air outlet 33, and a plurality of micro pores are provided on the film 331 to prevent the lubricating pump product from entering the stirring rod 3 through the air outlet 33. The film 331 is made of polytetrafluoroethylene (PTFE), which has excellent chemical stability and temperature resistance, and can withstand high temperature and high pressure for a long time without deformation and aging, thereby ensuring good air tightness inside and outside the stirring rod 3. The film 331 can be fixed to the opening of the side wall of the stirring rod 3 by thermal welding or gluing to ensure excellent sealing effect.

[0034] The implementation principle of the concrete pumping lubricant product transportation equipment of the present application embodiment is as follows: during the driving process of the transport vehicle 1, the power take-off device 14 is used to intercept part of the kinetic energy generated by the vehicle engine transmission system, and the oil pump motor 11 is driven to work, and the hydraulic oil flows to the hydraulic reversing valve 25 through the oil delivery pipe 12, and the hydraulic oil is controlled by the hydraulic reversing valve 25 to enter from the oil inlet of the hydraulic motor 24, and then flows out from the oil outlet of the hydraulic motor 24, thereby driving the hydraulic motor 24 to work, driving the stirring shaft to rotate, and stirring the lubricant mortar or other lubricant products in the storage barrel 2, and the hydraulic oil flowing out from the oil outlet of the hydraulic motor 24 flows back to the hydraulic reversing valve 25, and finally flows back to the oil pump motor 11 through the return oil pipe 13 for circulation; When the transport vehicle 1 arrives at the construction site and parks for construction, the kinetic energy generated by the electric motor 15 drives the oil pump motor 11 to work, thereby achieving real-time stirring of the pump-lubricating mortar or other pump-lubricating products during transportation and at the construction site, thereby ensuring the uniformity and stability of the pump-lubricating mortar or other pump-lubricating products, avoiding the pump-lubricating mortar or other pump-lubricating products from being adsorbed on the barrel wall of the storage barrel 2, and reducing material waste.
