Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, and in particular to a concrete pouring device. Background Art

[0002] Overhead steel operating platform is an elevated platform made of steel. It is suspended above the ground and can provide workers with a safe and convenient working space. Overhead steel operating platform is usually used in indoor factories, warehouses and production lines, etc., to help workers complete their work tasks efficiently in these places. Overhead steel operating platform has the characteristics of simple structure, easy installation, good stability and high reliability. It is one of the most important facilities in modern industrial production.

[0003] The pouring of overhead steel operating platform generally refers to laying concrete on the overhead steel structure frame. According to the requirements and characteristics of the specific project, different pouring methods are selected, such as suction pouring method: the concrete is transported to the formwork through pipes and dust suction ports, which is suitable for construction sites that are difficult to reach.

[0004] When the suction pouring method is used, concrete is likely to remain inside the pipe after pouring. After the concrete solidifies inside the pipe, it will block the pipe, resulting in poor pouring effect next time. When the blockage is serious, it will also cause the pipe to be scrapped. Therefore, the pipe needs to be cleaned after pouring.

[0005] At present, the following methods are generally used for cleaning pipelines:

[0006] 1. Cleaning the pipe: First, use a cleaning pump and a cleaning head to clean the pipe. The cleaning pump uses a high-pressure jet of water to loosen the remaining concrete in the pipe. The cleaning head can enter the pipe to clean the concrete residue according to the size of the pipe diameter.

[0007] 2. Invert the pipe: If necessary, the pipe can be inverted to discharge the remaining concrete particles and sediment.

[0008] 3. Use special cleaning solvents: When necessary, special chemical cleaning solvents can be used to chemically dissolve the concrete residue before cleaning;

[0009] When using clean water for cleaning, a large amount of clean water is needed, and a large amount of waste water will be generated after cleaning, which is not convenient for use in places where water resources are scarce. The large amount of waste water generated increases the burden of recycling construction waste and increases the recycling cost of construction waste. The waste water generated is easy to seep into the ground, which will cause pollution to the environment.

[0010] When the pipe is inverted for cleaning, only loose concrete with weak adsorption can be discharged. Concrete with strong adsorption still needs to be cleaned with clean water or special cleaning solvents, which will increase the burden of construction waste recycling and increase the recycling cost of construction waste.

[0011] Special cleaning solvents are generally divided into two types: alkaline and acidic. Acidic cleaners: Acidic cleaners usually use strong acids such as hydrochloric acid or nitric acid to clean concrete residues;

[0012] Alkaline cleaners: Alkaline cleaners usually use alkaline substances such as sodium hydroxide and calcium hydroxide to clean concrete residues.

[0013] The following hazards may occur when using cleaning agents:

[0014] 1. Corrosion hazards: Both acidic and alkaline cleaning agents are corrosive to a certain extent, which may cause damage to the surface of pipes, equipment, etc., and even cause equipment failure. They also cause certain irritation and harm to the human body.

[0015] 2. Environmental pollution: During the cleaning process, both the cleaning agent and the waste liquid after cleaning may cause environmental pollution. Acidic or alkaline cleaning solvents may destroy the acid-base environment of the soil, and in severe cases, it may cause the land to become a desertified area.

[0016] 3. Improper operation may cause harm to the human body: Acidic or alkaline cleaning agents are generally irritating. When using them, you must strictly follow the instructions and take protective measures to avoid causing harm to the human body.

[0017] Moreover, when the inside of the pipeline is cleaned by the above-mentioned cleaning, a large amount of concrete will be wasted, which increases the cost of pouring. Therefore, it is necessary to design a concrete pouring device. Summary of the invention

[0039] Compared with the prior art, the present invention provides a concrete pouring device having the following

[0040] Beneficial effects:

[0041] 1. The method for casting the overhead steel operating platform adds a cylindrical rubber column with an outer diameter not less than the inner diameter of the transmission pipe to the inside of the transmission pipe, and uses high-pressure air to push the rubber column to move in the transmission pipe, so that all the concrete remaining in the transmission pipe is discharged, thereby reducing the cost of cleaning, reducing the waste of water resources and avoiding pollution to the environment;

[0042] 2. The concrete pouring device puts a rubber column into the first installation pipe through the feed port, and then seals the feed port through the plugging part, absorbs external air through the pusher, and uses air pressure to push the rubber column to slide inside the first installation pipe and the transmission pipe, so as to squeeze the concrete adsorbed on the first installation pipe and the transmission pipe onto the operating platform bracket, so as to make full use of the concrete, and there is no need to clean the pipe with clean water or detergent, thereby preventing secondary pollution;

[0043] 3. The concrete pouring device prevents the concrete from flowing back through the blocking block. At the same time, the push barrel, the first mounting pipe and the blocking block cooperate to squeeze the concrete, thereby improving the density and compressive strength of the concrete. Through squeezing, the air and moisture in the concrete can be better removed, and the porosity in the concrete can be reduced, so that the concrete can obtain higher density and strength;

[0044] 4. The concrete pouring device absorbs the vibration generated by the first mounting pipe through the rubber strip, thereby reducing the vibration transmitted to the electric telescopic cylinder and protecting the electric telescopic cylinder. The force generated by the first mounting pipe when it vibrates and falls causes the rubber strip and the first spring to contract. Therefore, when the first mounting pipe rises, the rubber strip and the first spring rebound, promoting the first mounting pipe to rise, thereby promoting the vibration of the first mounting pipe.

[0045] 5. The vibrating part of the concrete pouring device pre-vibrates the concrete to remove air and moisture in the concrete in advance, thereby improving the density and compressive strength of the concrete, reducing the vibration time after pouring, and improving construction efficiency. At the same time, the first installation pipe and the transmission pipe vibrate, and the force generated by the vibration will vibrate off the concrete adsorbed on the walls of the installation pipe and the transmission pipe, further promoting the cleaning of the concrete inside the pipeline.

[0066] S900. Site cleaning: After the entire pouring process is completed, the site must be cleaned up in a timely manner and concrete residues must be cleaned up in a timely manner to ensure the cleanliness and safety of the site.

[0067] Embodiment 2:

[0068] Reference Figure 1-Figure 7 According to the method in Example 1, we propose a concrete pouring device, including a base 1 and a shock-absorbing support arranged on the base 1; a first mounting tube 2 connected to the shock-absorbing support, the top of the first mounting tube 2 is fixedly connected to a feed pipe 4, the feed pipe 4 is obliquely arranged on the first mounting tube 2, and a feed port 5 is opened on the tube wall of the feed pipe 4; a blocking part arranged on the feed pipe 4 for blocking the feed port 5; a pushing cylinder 8 slidably connected to the first mounting tube 2, and a driving part for driving the pushing cylinder 8 to slide back and forth is arranged on the base 1; a vibrating part is arranged on the base 1, and the vibrating part is used to drive the first mounting tube 2 to vibrate; a second mounting tube 3 fixedly connected to the top of the first mounting tube 2, and a blocking part for preventing concrete backflow is arranged on the second mounting tube 3.

[0069] When in use, the transmission pipe is installed on the first installation pipe 2 through a flange. The inner diameter of the transmission pipe is the same as the inner diameter of the first installation pipe 2. A rubber sealing ring is provided at the connection to prevent leakage of concrete during transmission.

[0070] Pour concrete from the feed port 5 into the feed pipe 4, the concrete flows into the first installation pipe 2 through the feed pipe 4, and the push cylinder 8 is driven by the driving part to slide back and forth to push the concrete entering the first installation pipe 2 in the direction of the second installation pipe 3. When passing through the blocking part, the blocking part is pushed open to connect the first installation pipe 2, and the concrete is pushed into the transmission pipe, so that it is discharged to the operating platform bracket through the transmission pipe. After the pouring is completed, the feeding is stopped, and the feed port 5 is blocked by the blocking part. The push cylinder 8 reciprocates through the blocking part to absorb external air, increase the air pressure in the first installation pipe 2, and push the concrete into the transmission pipe. Then the blocking part opens the feed port 5, and then a material with a diameter not less than that of the first installation pipe is put into the first installation pipe 2 through the feed port 5. 2 is a cylindrical rubber column with an inner diameter of the transmission pipe. In order to prevent the rubber column from being unable to be completely inserted into the first mounting pipe 2, the diameter of the rubber column is 0.1mm-3mm wider than the inner diameter of the first mounting pipe 2. Then the feed port 5 is sealed here by the sealing portion, and the external air is sucked through the pushing cylinder 8. The air pressure is used to push the rubber column to slide inside the first mounting pipe 2 and the transmission pipe. Since the diameter of the rubber column is not less than the inner diameter of the first mounting pipe 2 and the transmission pipe, the rubber column is tightly attached to the inner walls of the two pipes. When the rubber column moves, the concrete adsorbed on the first mounting pipe 2 and the transmission pipe is squeezed onto the operating platform bracket, so that the concrete is fully utilized, and there is no need to clean the pipe with clean water or detergent, thereby preventing secondary pollution.

[0071] Reference Figure 2 and Figure 4 The driving part includes an electric telescopic cylinder 6 fixedly connected to the base 1, and an articulated ball 7 is fixedly connected to the output end of the electric telescopic cylinder 6. A ball groove is opened on the pushing barrel 8, and the articulated ball 7 is articulated in the ball groove. A spherical rubber pad 9 is fixedly connected in the ball groove, and the articulated ball 7 is articulated with the spherical rubber pad 9.

[0072] When the output rod of the electric telescopic cylinder 6 reciprocates and retracts, the push cylinder 8 is pushed to slide reciprocally inside the first mounting tube 2 through the hinged ball 7. At the same time, because the connection is made through the hinged ball 7, and a spherical rubber pad is provided between the hinged ball 7 and the push cylinder 8 as a buffer, when the vibration part causes the first mounting tube 2 to vibrate, the electric telescopic cylinder 6 can be effectively prevented from vibrating, thereby reducing damage to the electric telescopic cylinder 6.

[0073] Reference Figure 5 The blocking portion includes a blocking block 32, a slide groove 31 is provided in the second mounting tube 3, the blocking block 32 is slidably connected to the slide groove 31, a second spring 33 is provided in the second mounting tube 3, and the two ends of the second spring 33 are fixedly connected to the second mounting tube 3 and the blocking block 32 respectively.

[0074] When the push barrel 8 moves back and forth, it pushes the concrete toward the blocking block 32. After the push barrel 8 blocks the feed hole on the first mounting tube 2, it continues to move toward the blocking block 32. The push barrel 8 cooperates with the first mounting tube 2 to squeeze the concrete. As the pressure increases, the concrete lifts the blocking block 32, and the blocking block 32 slides in the second mounting tube 3, causing the second spring 33 to contract and push the concrete to the other end of the blocking block 32. Then, after the push barrel 8 returns, the blocking block 32 loses its force, and the second spring 33 rebounds to reset the blocking block 32, thereby blocking the first mounting tube 2 to prevent the concrete from flowing back.

[0075] In the present invention, the blocking block 32 is used to prevent the concrete from flowing back. At the same time, the push barrel 8, the first mounting tube 2 and the blocking block 32 cooperate to extrude the concrete, thereby improving the density and compressive strength of the concrete. Through extrusion, the air and moisture in the concrete can be better removed, and the porosity in the concrete can be reduced, so that the concrete can obtain higher density and strength.

[0076] Reference Figure 2 The blocking portion includes a first mounting plate 11 fixedly connected to the nozzle of the feed pipe 4, two screw rods 12 are rotatably connected to the first mounting plate 11, and a blocking block 13 is threadedly connected to the two screw rods 12. A one-way valve for air intake is provided on the blocking block 13, and the blocking block 13 is slidingly connected to the feed pipe 4. A second mounting plate 14 is provided on the two screw rods 12, and the two screw rods 12 are rotatably connected to the second mounting plate 14. An adjusting disk 15 is rotatably connected to the second mounting plate 14, and the adjusting disk 15 rotates synchronously with the screw rod 12 through a spur gear set 16.

[0077] By rotating the adjusting disk 15, the adjusting disk 15 drives the two screw rods 12 to rotate through the spur gear set 16. The threads on the screw rods 12 are in opposite directions. The screw rods 12 rotate to drive the blocking block 13 to move, thereby blocking the feed port 5 and connecting the feed port 5. Furthermore, a drive motor can be fixedly installed on the second mounting plate 14, and the drive motor is used to drive the screw rod 12 to rotate.

[0078] Reference Figure 7 The shock-absorbing support includes a fixed seat 27 fixedly connected to the base 1, a sliding seat 28 is slidably connected to the fixed seat 27, a rubber strip 29 is arranged between the sliding seat 28 and the fixed seat 27, a first spring 30 is fixedly connected to the fixed seat 27, and the top of the first spring 30 is fixedly connected to the sliding seat 28.

[0079] When the vibration part causes the first mounting tube 2 to vibrate, the rubber strip 29 absorbs the vibration generated by the first mounting tube 2, thereby reducing the vibration transmitted to the electric telescopic cylinder 6, protecting the electric telescopic cylinder 6, and the force generated by the downward movement of the first mounting tube 2 during vibration causes the rubber strip 29 and the first spring 30 to contract. Therefore, when the first mounting tube 2 rises, the rubber strip 29 and the first spring 30 rebound, promoting the first mounting tube 2 to rise, and thereby promoting the vibration of the first mounting tube 2.

[0080] Reference Figure 2 and Figure 7 The vibration part includes a connecting plate 17 fixedly connected to the base 1, and the connecting plate 17 is rotatably connected to the mounting shaft 18, and the mounting shaft 18 is fixedly connected to a crankshaft 19, and a mounting seat 21 is fixedly connected to the bottom of the first mounting tube 2, and a crank 20 is rotatably connected to the mounting seat 21, and the crank 20 is rotatably connected to the eccentric shaft of the crankshaft 19, and the mounting shaft 18 is connected to the output rod of the electric telescopic cylinder 6 through a speed increasing part, and the speed increasing part includes a rack 25 slidably connected to the base 1, a speed increasing box 22 fixedly connected to the base 1 and a rotating shaft 23 rotatably connected to the base 1, and a mounting disk 10 is fixedly connected to the output rod of the electric telescopic cylinder 6, and the mounting disk 10 is fixedly connected to the rack 25, and a transmission gear 26 meshing with the rack 25 is fixedly connected to the top of the rotating shaft 23, and the rotating shaft 23 and the input shaft of the speed increasing box 22 rotate synchronously through a bevel gear set 24, and the output shaft of the speed increasing box 22 is fixedly connected to the mounting shaft 18.

[0081] When the output rod of the electric telescopic cylinder 6 reciprocates and retracts, the mounting plate 10 is driven to reciprocate. When the mounting plate 10 reciprocates, the rack 25 is driven to slide reciprocatingly. The reciprocating sliding of the rack 25 drives the transmission gear 26 to rotate. The transmission gear 26 drives the rotating shaft 23 to rotate. The rotating shaft 23 drives the input shaft of the speed increaser 22 to rotate through the bevel gear set 24. The output shaft of the speed increaser 22 drives the mounting shaft 18 to rotate. The mounting shaft 18 drives the crankshaft 19 to rotate. The crankshaft 19 drives the first mounting tube 2 to vibrate reciprocatingly up and down through the crank 20.

[0082] In order to prevent stress from being generated when the internal gears of the speed increasing box 22 rotate forward and reverse, which may damage the internal gears of the speed increasing box 22 , a ratchet mechanism may be provided between the transmission gear 26 and the rotating shaft 23 .

[0083] In the present invention, the concrete is pre-vibrated by the vibrating part to remove the air and moisture in the concrete in advance, thereby improving the density and compressive strength of the concrete, reducing the vibration time after pouring, and improving the construction efficiency. At the same time, the first installation pipe 2 and the transmission pipe vibrate, and the force generated by the vibration will vibrate off the concrete adsorbed on the walls of the installation pipe and the transmission pipe, further promoting the cleaning of the concrete inside the pipeline.

[0084] In order to prevent the vibration amplitude of the first mounting tube 2 from being too large, the axis distance between the axis center of the eccentric shaft of the crankshaft 19 and the axis center of the crankshaft 19 is 1mm-3mm.
