Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, and in particular to a self-compacting concrete conveying device for curved steel shell composite cable towers. Background Technology

[0002] When pouring concrete inside a curved steel shell, especially in soft soil and for bridge piers with high heights, large concrete pumps are difficult to access due to height restrictions. Furthermore, concrete pouring usually requires sunny or warm weather to ensure continuity and quality. This leads to the following problems:

[0003] 1. Most bridges are built to cross waterways, and the soil near water is generally soft, such as sandy soil. This makes it difficult for large-tonnage equipment to enter the site when pouring concrete.

[0004] 2. Cable towers are generally very tall, so even if it is just the concrete pouring of the bottom section of the cable tower, it is difficult for ordinary concrete pump trucks to reach the height of the concrete pouring pump. Moreover, the sand layer is prone to instability when it is rolled by the pump truck for a long time.

[0005] When casting curved steel shells, they easily heat up or even become scalding after being exposed to sunlight. Once the concrete is poured in, it is easy for the water to evaporate quickly, which directly affects the quality of the concrete pouring. Therefore, a self-compacting concrete conveying device for curved steel shell composite cable towers is designed. Summary of the Invention

[0006] Based on the existing technical problems that make it difficult for large equipment to enter the site during the pouring of curved steel shells, and that the evaporation of concrete moisture during pouring can affect the quality of concrete pouring, this invention proposes a self-compacting concrete conveying device for curved steel shell composite cable towers.

[0007] The present invention proposes a self-compacting concrete conveying device for a curved steel shell composite cable tower, comprising a magnetic track set on the surface of the curved steel shell, a balancing moving platform set on the upper surface of the curved steel shell, a pump pipe mounting and traveling device set outside the magnetic track, and the pump pipe mounting and traveling device being fixedly connected to the lower surface of one end of the balancing moving platform.

[0008] The magnetic track is used to guide the balancing moving platform and the pump pipe installation walking device.

[0009] The balancing moving platform is used to fix one end of the pump pipe, so that the outlet of the pump pipe is always aligned with the inside of the curved steel shell.

[0010] The pump pipe installation and walking device is used to drive the balance moving platform to move along the surface of the curved steel shell, thereby synchronously pouring concrete into the curved steel shell.

[0011] Preferably, the magnetic track includes a track section and a docking mechanism. Both sides of the track section are provided with spherical hinge interfaces, and the side surface of the track section is provided with a T-shaped guide groove.

[0012] The above technical solution allows for the connection between the track section and the docking mechanism via a spherical hinge interface, enabling adjustment of the size of the magnetic track and allowing it to be installed on curved steel shell surfaces of different sizes.

[0013] Preferably, the docking mechanism includes two symmetrically arranged hinged balls, one end of which is fixedly connected to a T-shaped connecting rod, and the other end of which is fixedly connected to a main connecting sleeve that movably engages with the outer surface of the T-shaped connecting rod.

[0014] The above technical solution enables the docking of adjacent track sections by engaging the T-shaped connecting rod with the main connecting sleeve, thereby splicing the magnetic track.

[0015] Preferably, the balancing moving platform includes a U-shaped moving block, and the inner surfaces on both sides and the lower surface in the middle of the U-shaped moving block are respectively provided with a wall-adhering walking component and a planar walking component. The wall-adhering walking component includes a telescopic sleeve installed on the inner surfaces on both sides of the U-shaped moving block.

[0016] The above technical solution enables the U-shaped moving block to move smoothly on the curved steel shell surface through the wall-mounted walking component and the planar walking component.

[0017] Preferably, a Y-shaped support rod is movably inserted into the inner wall of the telescopic sleeve, a compression spring is provided between the Y-shaped support rod and the telescopic sleeve, and a side roller is installed at the end of the Y-shaped support rod via a pin. The planar traveling component includes a mounting seat installed on the lower surface of the middle part of the U-shaped moving block, and a planar roller is installed on the lower inner wall of the mounting seat.

[0018] The above technical solution enables the U-shaped moving block to slide smoothly while the side rollers and flat rollers move, thereby driving the pump pipe installation walking device to move and pour concrete onto the curved steel shell.

[0019] Preferably, a counterweight water tank is fixedly connected to the lower surface of one end of the balancing moving platform. Valves are installed on the inner bottom wall and the water inlet of the counterweight water tank. A transverse sliding groove is formed on the upper surface of the U-shaped moving block. A counterweight block with a rack on one side is installed on the inner wall of the transverse sliding groove. An installation cavity for installing a servo motor is formed on the inner bottom wall of the transverse sliding groove. A transmission gear that meshes with the rack is fixedly sleeved on the outer surface of the main shaft of the servo motor.

[0020] The above technical solution allows for the control of water inlet and outlet in the counterweight water tank via two valves, which can offset the weight of the concrete during its transport within the pump pipe, thus ensuring that the two ends of the U-shaped moving block are in a balanced state.

[0021] Preferably, the pump pipe mounting and walking device includes a magnetic walking seat that cooperates with the magnetic track, and a water spray block is fixedly connected between every two adjacent magnetic walking seats. The water spray block on the uppermost magnetic walking seat is fixedly connected to the lower surface of the balance moving platform.

[0022] The above technical solution enables the balanced moving platform to move on the curved steel shell by coordinating the magnetic walking seat and the magnetic track, while the water spray block sprays water onto the surface of the curved steel shell to cool it down.

[0023] Preferably, one side surface of the magnetic walking seat is provided with a funnel-shaped mounting groove, and the inner wall of the mounting groove is respectively equipped with a first gripper and a second gripper, and one end surface of the first gripper is fixedly connected to the inner bottom wall of the mounting groove.

[0024] The above technical solution enables the pump pipe to be supported by the first and second clamps, and limits the connection method between the first clamp and the mounting groove.

[0025] Preferably, a drive motor is mounted on the upper surface of the magnetic walking seat, the main shaft of the drive motor is fixedly connected to the second gripper, and anti-slip pads are installed on the inner walls of both the first gripper and the second gripper, which fix the pump pipe.

[0026] The above technical solution enables the second gripper to rotate via a drive motor, thereby controlling the opening and closing of the first and second grippers to install the pump pipe, and preventing the pump pipe from sliding arbitrarily via an anti-slip pad.

[0027] Preferably, a secondary connecting sleeve is installed on one side surface of the first gripper, a drive nut is rotatably connected to one end of the secondary connecting sleeve, an installation rod is movably sleeved on the inner wall of the secondary connecting sleeve, the inner wall of the drive nut is threadedly connected to the outer surface of the installation rod, a clamp for fixing the water pipe is fixedly connected to one end of the installation rod, a first channel and a second channel are respectively opened on the inner wall of the U-shaped moving block, the end of the pump pipe is installed through the first channel, the end of the pump pipe is threadedly connected to the inner wall of one end of the first channel, and the water pipe extends through the second channel into the counterweight water tank.

[0028] The above technical solution enables the water pipe to be fixed by clamps, and the clamps are fixed on the first jaw by the cooperation of the drive nut and the installation rod.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. By setting up a magnetic track, the balance moving platform and pump pipe installation walking device can move along the surface of the curved steel shell. The splicing of the track section and docking mechanism can be adjusted when there are errors in the size of the curved steel shell, so that the magnetic track can be used on curved steel shells of different sizes. The structure is compact and avoids the need for large equipment to enter the site.

[0031] 2. By setting up a balancing moving platform, the U-shaped moving block is simply placed on top of the curved steel shell. Concrete is then poured into the curved steel shell through the pump pipe. At the same time, water is added to the counterweight water tank to ensure that the U-shaped moving block can be placed stably on the curved steel shell. The movement of the balancing moving platform pours the concrete evenly into the curved steel shell, thus quickly completing the concrete pouring and ensuring the quality of the entire circumference of the curved steel shell.

[0032] 3. By setting up a pump pipe installation and walking device, the pump pipe can be fixed by the first and second clamps, and the water pipe can be fixed by the clamps. The water pipe supplies water into the spray block, so that the water is sprayed out from the spray block to cool the surface of the curved steel shell, reduce the rate of water evaporation of the concrete, and ensure the quality of pouring.

Detailed Implementation

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Reference Figures 1-8A self-compacting concrete conveying device for a curved steel shell composite cable tower includes a magnetic track set on the surface of the curved steel shell, a balancing moving platform set on the upper surface of the curved steel shell, and a pump pipe 313 mounting and traveling device set on the outside of the magnetic track. The pump pipe 313 mounting and traveling device is fixedly connected to the lower surface of one end of the balancing moving platform.

[0044] like Figures 1-8 As shown, the magnetic track is used to guide the balance moving platform and the pump pipe 313 to install the walking device. The magnetic track includes track sections 1 and docking mechanisms. In order to realize the connection between track sections 1, spherical hinge interfaces 11 are provided on both sides of the track section 1. In order to cooperate between the track section 1 and the pump pipe 313 to install the walking device, a T-shaped guide groove is provided on the side surface of the track section 1. The track section 1 and the docking mechanism can be connected through the spherical hinge interfaces 11. The size of the magnetic track can be adjusted so that it can be installed on curved steel shell surfaces of different sizes. The docking mechanism includes two symmetrically arranged hinged balls 12. In order to connect the two track sections 1, a T-shaped connecting rod 13 is fixedly connected to one end of one hinged ball 12, and a main connecting sleeve 14 that movably fits onto the outer surface of the T-shaped connecting rod 13 is fixedly connected to one end of the other hinged ball 12. The adjacent track sections 1 can be docked by the snap-fit ​​between the T-shaped connecting rod 13 and the main connecting sleeve 14, thereby splicing the magnetic track.

[0045] By setting up a magnetic track, the balance moving platform and the pump pipe 313 installation walking device can move along the surface of the curved steel shell. Furthermore, the splicing of the track section 1 and the docking mechanism allows for size adjustment when there are errors in the dimensions of the curved steel shell. This makes the magnetic track suitable for curved steel shells of different sizes, with a compact structure that avoids the need for large equipment to be brought on site.

[0046] like Figures 1-5 and Figure 8 As shown, the balancing moving platform is used to fix one end of the pump pipe 313 so that the outlet of the pump pipe 313 is always aligned with the inside of the curved steel shell. The balancing moving platform includes a U-shaped moving block 2. The inner surfaces on both sides and the lower surface in the middle of the U-shaped moving block 2 are respectively provided with a wall-adhering walking component and a planar walking component. The wall-adhering walking component includes a telescopic sleeve 21 installed on the inner surfaces on both sides of the U-shaped moving block 2. The wall-adhering walking component and the planar walking component can control the U-shaped moving block 2 to move smoothly on the surface of the curved steel shell.

[0047] To install the side roller 24 and control the smooth movement of the U-shaped moving block 2 when it moves to the corner, a Y-shaped support rod 22 is movably inserted into the inner wall of the telescopic sleeve 21. A compression spring 23 is provided between the Y-shaped support rod 22 and the telescopic sleeve 21, and the side roller 24 is installed at the end of the Y-shaped support rod 22 via a pin. To guide the U-shaped moving block 2 and the curved steel shell, the planar walking component includes a mounting seat 25 installed on the lower surface of the middle part of the U-shaped moving block 2, and a planar roller 26 is installed on the lower inner wall of the mounting seat 25. As the U-shaped moving block 2 moves, the side roller 24 and the planar roller 26 enable the U-shaped moving block 2 to slide smoothly, thereby driving the pump pipe 313 to move and pour concrete on the curved steel shell.

[0048] To counterweight the two sides of the balancing moving platform, a counterweight water tank 27 is fixedly connected to the lower surface of one end of the balancing moving platform. To control the inflow and outflow of water inside the counterweight water tank 27, valves 28 are installed on the inner bottom wall and the inlet of the counterweight water tank 27. To further counterweight the U-shaped moving block 2, a transverse groove 29 is provided on the upper surface of the U-shaped moving block 2, and a counterweight block 211 with a rack 210 on one side is installed on the inner wall of the transverse groove 29. To drive the counterweight block 211 to move, a mounting cavity for mounting a servo motor 212 is provided on the inner bottom wall of the transverse groove 29, and a transmission gear 213 that meshes with the rack 210 is fixedly sleeved on the outer surface of the main shaft of the servo motor 212. The inflow and outflow of water in the counterweight water tank 27 can be controlled by the two valves 28 of the counterweight water tank 27, which can offset the weight brought by the transportation of concrete in the pump pipe 313, so that the two ends of the U-shaped moving block 2 are in a balanced state.

[0049] By setting up a balancing moving platform, the U-shaped moving block 2 is simply placed on top of the curved steel shell, and concrete is poured into the interior of the curved steel shell through the pump pipe 313. At the same time, water is added to the counterweight water tank 27 so that the U-shaped moving block 2 can be placed stably on the curved steel shell. The movement of the balancing moving platform pours the concrete evenly into the curved steel shell, thereby quickly completing the concrete pouring and ensuring the quality of the entire circumference of the curved steel shell.

[0050] like Figures 1-5 and Figure 8As shown, the pump pipe 313 is equipped with a walking device to drive the balancing moving platform to move along the surface of the curved steel shell, thereby synchronously pouring concrete onto the curved steel shell. The pump pipe 313 is equipped with a walking device including a magnetic walking seat 3 that cooperates with the magnetic track. In order to cool the surface of the curved steel shell, a water spray block 31 is fixedly connected between every two adjacent magnetic walking seats 3. The water spray block 31 on the uppermost magnetic walking seat 3 is fixedly connected to the lower surface of the balancing moving platform. The magnetic walking seat 3 and the U-shaped moving block 2 can be connected through the water spray block 31. The cooperation between the magnetic walking seat 3 and the magnetic track controls the movement of the balancing moving platform on the curved steel shell. At the same time, the water spray block 31 sprays water onto the surface of the curved steel shell to cool it down.

[0051] To install the first gripper 33 and the second gripper 34, a funnel-shaped mounting groove 32 is provided on one side surface of the magnetic travel base 3. The first gripper 33 and the second gripper 34 are respectively installed on the inner wall of the mounting groove 32, and one end surface of the first gripper 33 is fixedly connected to the inner bottom wall of the mounting groove 32, indicating that the first gripper 33 cannot move. The pump pipe 313 can be supported by the first gripper 33 and the second gripper 34, and the connection method between the first gripper 33 and the mounting groove 32 is defined. In order to drive the second gripper 34, the magnetic travel base 3... A drive motor 35 is mounted on the upper surface, and the main shaft of the drive motor 35 is fixedly connected to the second gripper 34. In order to protect the first gripper 33 and the second gripper 34 from the pump tube 313, anti-slip pads 36 are installed on the inner walls of the first gripper 33 and the second gripper 34. The first gripper 33 and the second gripper 34 fix the pump tube 313. The drive motor 35 can drive the second gripper 34 to rotate, thereby controlling the opening and closing of the first gripper 33 and the second gripper 34 to install the pump tube 313. The anti-slip pads 36 prevent the pump tube 313 from sliding randomly.

[0052] To install the clamp 310, a secondary connecting sleeve 37 is installed on one side surface of the first gripper 33. Further, a drive nut 38 is rotatably connected to one end of the secondary connecting sleeve 37. To allow the mounting rod 39 to retract into the secondary connecting sleeve 37, the mounting rod 39 is movably sleeved on the inner wall of the secondary connecting sleeve 37. To control and fix the mounting rod 39 within the secondary connecting sleeve 37, the inner wall of the drive nut 38 is threaded to the outer surface of the mounting rod 39. To install the water pipe 314, a clamp 310 for fixing the water pipe 314 is fixedly connected to one end of the mounting rod 39. To connect the pump pipe 313 and the water pipe 314... For installation, a first channel 311 and a second channel 312 are respectively opened on the inner wall of the U-shaped moving block 2. The end of the pump pipe 313 is installed through the first channel 311. The end of the pump pipe 313 is threaded to one end of the inner wall of the first channel 311. The water pipe 314 extends through the second channel 312 into the counterweight water tank 27. The water pipe 314 can be fixed by the clamp 310. The clamp 310 is fixed on the first clamp 33 by the cooperation of the drive nut 38 and the mounting rod 39. In order to supply water in the water pipe 314 to the water spray block 31, a connecting hose 315 is fixedly connected between the water pipe 314 and the water spray block 31.

[0053] By installing a walking device on the pump pipe 313, the pump pipe 313 can be fixed by the first clamp 33 and the second clamp 34, and the water pipe 314 can be fixed by the clamp 310. The water pipe 314 supplies water into the spray block 31, so that the water is sprayed out from the spray block 31 to cool the surface of the curved steel shell, reduce the rate of water evaporation of the concrete, and ensure the quality of the pouring.

[0054] Working principle: When it is necessary to pour concrete into the inside of the curved steel shell, the device is hoisted onto the top of the curved steel shell by a crane. The flat roller 26 keeps the U-shaped moving block 2 stable on the curved steel shell. At the same time, the side roller 24 guides and limits the two sides of the U-shaped moving block 2. Since the Y-shaped support rod 22 cooperates with the compression spring 23 and the telescopic sleeve 21, when the U-shaped moving block 2 moves to the bend, the side roller 24 is always in contact with the curved steel shell, thereby controlling the smooth movement of the U-shaped moving block 2, and driving one end of the pump pipe 313 to move with the movement of the U-shaped moving block 2.

[0055] After the U-shaped moving block 2 is placed stably, the drive motor 35 is controlled to drive the second gripper 34 to rotate, so that the first gripper 33 and the second gripper 34 open relative to each other, clamping the pump pipe 313. The pump pipe 313 is prevented from slipping by the anti-slip pad 36, and the installation rod 39 is connected to the auxiliary connecting sleeve 37 by rotating the drive nut 38. The water pipe 314 is installed by the clamp 310. Through the connection between the water pipe 314 and the water spray block 31, the water in the water pipe 314 flows into multiple water spray blocks 31 and sprays out from one side of the water spray block 31 to cool the surface of the curved steel shell, slow down the evaporation rate of the concrete, and thus improve the pouring quality of the concrete.

[0056] When concrete is transported in the pump pipe 313, the gravity at one end of the U-shaped moving block 2 will suddenly increase. Water is then transported to the counterweight box for storage through the water pipe 314. When the concrete is being transported through the pump pipe 313, the impact force is too great, so the servo motor 212 controls the transmission gear 213 to rotate. When the transmission gear 213 rotates, the counterweight block 211 is controlled to move towards the side of the balance moving block closer to the counterweight water tank 27.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
