Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of concrete construction, and particularly to a concrete placing boom for building construction with an anti-setting structure. Background Art
[0002] In the patent application with the application publication number CN119195486A, it includes an upright frame and a conveying pipe group. The conveying pipe group includes a feeding pipe and an extension pipe. One end of the extension pipe far from the feeding pipe is bent vertically downward. A rotating frame is further arranged outside the end of the extension pipe far from the feeding pipe. The rotating frame is rotatably connected to the upright frame. A rotating member is also arranged on the upright frame, and the rotating member is used to drive the rotating frame to rotate. The conveying pipe group further includes a flexible pipe and a telescopic pump pipe. One end of the flexible pipe is communicated with the extension pipe, and the other end is communicated with the feeding end of the telescopic pump pipe. The telescopic pump pipe is arranged on the rotating frame, and the discharging end is arranged obliquely downward. The adjusting assembly is used to adjust the height of the discharging end of the telescopic pump pipe. The advantages are as follows: The setting of the telescopic pump pipe and the adjusting assembly enables the adjusting assembly to change the height of the discharging end of the telescopic pump pipe, and the telescopic function of the telescopic pump pipe can adjust the position of its own discharging end. Furthermore, the discharging end of the telescopic pump pipe can be fully close to the side area to be poured after adjustment, so that this application can pour the side area to be poured without additionally installing a chute or a launder, improving the pouring efficiency of the side of the pouring part. It also enables this application to adjust the pouring direction and angle in multiple directions, so that it can pour the restricted planes, beam-column-slab planes and multiple-angle vertical planes in the area to be poured, effectively improving the pouring efficiency and practicability of this application.
[0003] In the prior art including the above patent, when conducting concrete placing operations, the concrete is prone to initial setting or complete setting in the pipes of the placing boom due to reasons such as too high or too low environmental temperature, too long waiting time for raw materials, etc. If reverse pumping operations are performed at this time, there will be a risk of pipe explosion. If the corresponding pipes are removed and maintained, it will undoubtedly increase unnecessary work burdens and delay the project progress. Moreover, it should be noted that the most prone position for setting and blockage in the pipes is the elbow part. If not discovered in time, it will increase the probability of concrete setting in the upstream and downstream of the elbow, further increasing the work burden and reducing the work efficiency. In addition, when hoisting the existing manual placing boom, in order to ensure construction safety, the counterweight needs to be disassembled in advance. During hoisting, workers need to level the equipment. When encountering placing booms with special sizes, auxiliary components such as balance beams and guide ropes need to be added. And the existing device requires at least three hoistings to complete hoisting or shifting, which will not only further increase the work burden of workers but also reduce the hoisting efficiency. Summary of the Invention
[0004] The problems to be solved by the present invention are as follows: When concrete is at the elbow of the pipeline of the placing boom, it is easy for aggregate deposition to occur due to different flow velocities on the inner and outer sides, resulting in condensation and blockage, and the existing equipment has relatively cumbersome procedures during hoisting.
[0005] To solve the above technical problems, the technical solution of the present invention is: A placing boom for building construction with an anti-condensation structure, including a mounting frame and a pipeline assembly installed on the mounting frame. The pipeline assembly mainly includes elbow one and elbow two. The internal components of elbow one and elbow two are both used to prevent the layering of concrete caused by different flow velocities of the inner and outer layers at the elbow, which ultimately leads to a large amount of concrete remaining at the elbow. A sprinkler assembly that can be controlled to open by water pressure is also provided inside elbow one. The sprinkler assembly inside elbow one is used to replenish water to the concrete when the concrete starts to set. A counterweight assembly is arranged at the end of the small arm of the mounting frame.
[0006] Preferably, the pipeline assembly includes a feeding pipe, and the feeding pipes are all connected to the mounting frame. The feeding pipe under the large arm of the mounting frame is connected to elbow two. The feeding port of elbow one is connected to the upstream pipeline. The feeding port of elbow one can be parallel or perpendicular to the ground (when the upstream pipeline is below the feeding port of the elbow).
[0007] Preferably, the feeding port of elbow two is also connected to the upstream pipeline. The feeding port of elbow two can only be perpendicular to the ground (when the upstream pipeline is above the feeding port of the elbow). Cavities are provided on the pipe walls of the feeding pipe, elbow one, and baffle two, and cold and hot water for heat preservation and moisture preservation can pass through these cavities.
[0008] Preferably, an installation plate one is arranged inside elbow one. The shape of installation plate one is the same as that of the elbow, but only half of the elbow. A number of baffle plates one are fixedly arranged inside installation plate one. One baffle plate one is composed of two arc-shaped plates with an inclination angle. The baffle plates one gradually approach the center of the elbow from the feeding port to the discharging port. An opening for heat conduction and water supply is provided on installation plate one at the position of baffle plate one, and an opening is also provided on elbow one at the same position.
[0009] Preferably, an installation cylinder is fixedly arranged on the side of baffle plate one away from the inner space of elbow one. A spring is fixedly arranged inside the installation cylinder. The other end of the spring is fixedly provided with a sealing gasket. The sealing gasket is located on the side of baffle plate one close to the inner space of elbow one. A telescopic rod is arranged inside the spring, and both ends of the telescopic rod are fixedly connected to the installation cylinder and the sealing gasket respectively.
[0010] Preferably, an installation plate two is arranged inside elbow two. The specifications of installation plate two are the same as those of installation plate one. A baffle plate two is fixedly arranged inside installation plate two. Neither elbow two nor installation plate two is provided with an opening connected to the cavity.
[0011] Preferably, the counterweight assembly includes a fixed counterweight block fixedly installed below the end of the small arm of the mounting frame. The counterweight assembly further includes a steel cable passing through the middle of the fixed counterweight block, and one end of the steel cable close to the upper part of the mounting frame is wound around a take-up reel.
[0012] Preferably, a roller is provided between the steel cable and the take-up reel. Brackets are provided on both sides of the take-up reel. The lower ends of the brackets are fixedly connected to the mounting frame. The brackets are rotatably connected to the take-up reel. Porous plates are fixedly provided on both sides of the take-up reel.
[0013] Preferably, the porous plate is annularly arranged and can be fixedly connected to the bracket by bolts. A fence is provided on the outside of the fixed counterweight block. The fence is arranged in a "C" shape, and several movable counterweight blocks are arranged inside the fence.
[0014] Preferably, the movable counterweight blocks are fixed to the mounting frame by steel cables. A stop block is provided at the lower end of the lowermost movable counterweight block. The stop block is fixedly connected to the steel cable. The counterweight assembly further includes two symmetrical slide rails fixedly connected to the mounting frame. The slide rails are slidably connected to the fence and are fixed to the fence by bolts.
[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) Under the action of the pipeline assembly, first, it can reduce the stratification phenomenon that occurs when concrete passes through the elbow due to different flow velocities, and can continuously carry away the aggregate with the slurry, thereby reducing the probability of concrete deposition from the source. Moreover, both the baffle and the mounting plate can be replaced at any time without replacing the elbow, which can reduce the cost during use. Secondly, through the cavity and external components such as water pumps, water at different temperatures can be used to keep the concrete warm according to the ambient temperature, preventing the slurry from freezing due to low temperature and reducing the fluidity, and also preventing the slurry from evaporating too fast due to high temperature, which may lead to premature initial setting of the concrete. In this way, the influence of temperature on the concrete can be reduced, and the probability of concrete setting can be further reduced. Finally, when the concrete shows the initial setting phenomenon, the water pressure can be controlled to replenish water to the concrete, slowing down or eliminating the initial setting phenomenon, which can ensure the working efficiency and also provide time guarantee for workers to remove the pipes for maintenance; (2) With the help of the counterweight assembly, first of all, workers can complete the installation without relying on the tower crane. This not only shortens the time for installing the counterweight, but also simplifies the installation steps, without over-reliance on the experience of the tower crane driver and workers. Secondly, the installation of multiple counterweight blocks can enhance the modification capability of the device, so that the front arm can continue to extend to a certain extent without the need to purchase other types of equipment. Finally, through the enclosure, not only can the center of the device be placed on the support frame by utilizing its own weight, but the rotatable part of the device can also be locked, thereby further saving the preparation time before lifting. The position of the center of gravity can also be adjusted to facilitate lifting and reduce the probability of shaking during lifting. BRIEF DESCRIPTION OF THE DRAWINGS

The sprinkler assembly in the elbow 1 202 is used to replenish water to the concrete when the concrete starts to set. A counterweight assembly 3 is provided at the end of the small arm of the mounting frame 1.
[0021] The pipe assembly 2 includes a feeding pipe 201. The feeding pipes 201 are all connected to the mounting frame 1.

Neither the second elbow 203 nor the second mounting plate 2031 is provided with an opening connected to the cavity; at the flange of the first elbow 202 and the second elbow 203, grooves for installing the first mounting plate 2021 and the second mounting plate 2031 are provided. And during installation, the remaining part of the groove opening needs to be filled with a sealing ring to prevent concrete from entering the opened groove.
[0026] The counterweight assembly 3 includes a fixed counterweight block 301. The fixed counterweight block 301 is fixedly installed below the end of the small arm of the mounting frame 1. The counterweight assembly 3 also includes a steel cable 302. The steel cable 302 passes through the middle of the fixed counterweight block 301. One end of the steel cable 302 close to the upper part of the mounting frame 1 is wound around a winding shaft 303.
[0027] Between the steel cable 302 and the winding shaft 303, a roller 304 is arranged. On both sides of the winding shaft 303, brackets 305 are arranged. The lower ends of the brackets 305 are fixedly connected with the mounting frame 1. The brackets 305 are rotationally connected with the winding shaft 303. On both sides of the winding shaft 303, porous plates 306 are fixedly arranged.
[0028] The porous plate 306 is arranged in a ring shape. The porous plate 306 can be fixedly connected with the bracket 305 through bolts. On the outside of the fixed counterweight block 301, a fence 307 is arranged. The fence 307 is arranged in a "C" shape. Inside the fence 307, several movable counterweight blocks 308 are arranged.
[0029] The movable counterweight 308 is fixed to the mounting bracket 1 through a steel cable 302. A stop block 309 is provided at the lower end of the lowermost movable counterweight 308.

[0030] The working principle and usage process of the present invention: After the device is started, when the concrete passes through the elbow, it is divided into the following two situations: When the concrete passes through the elbow, under the action of centrifugal force, some of the aggregates in the concrete will break away from the slurry and flow to the outer arc of the elbow, while most of the slurry will flow through the inner arc of the elbow. Under the action of the baffle 2022 in the elbow 202, the aggregates can be forced to move towards the inner arc, and the aggregates are carried away by the slurry. Moreover, the subsequent aggregates will continuously impact the surface of the baffle 2022, thereby further reducing the residue of the aggregates. Also, after passing through the first baffle 2022, it will hit the rear baffle 2022 again and repeat the above process; When the concrete passes through the elbow 203, under the action of centrifugal force and gravity, the aggregates will still flow to the outer arc, while the slurry can, under the action of the baffle 2032, rush towards the aggregates at the outer arc. The aggregates can be carried away by the impact force of the slurry. And during maintenance, the impact force generated by the clean water passing through the baffle 2032 can also wash away the concrete in the middle of the elbow 203; It is worth mentioning that the cavities in the feeding pipe 201, the elbow 202, and the elbow 203 can be supplied with water through an external water pump, and the water temperature needs to be increased or decreased according to the ambient temperature during construction. By using this, heat preservation operations can be carried out on the concrete in winter and summer to prevent the water in the concrete from freezing and prevent the water in the concrete from evaporating too quickly; If during use, it is found that the concrete shows the phenomenon of initial setting, the water pressure can be increased. After the sealing gasket 2025 is pushed out by the water pressure, the concrete can be replenished with water in time to prevent or slow down the setting speed of the concrete; When the device is hoisted, the worker first loosens the bolts at the perforated plate 306 to unlock the winding shaft 303, lowers the movable counterweight 308, and then passes the stop block 309 through the counterweight to completely separate it from the device body; After retracting the steel cable 302 and re-fixing the winding shaft 303, loosen the bolts at the junction of the enclosure 307 and the slide rail 310, and move the enclosure 307 to the outside of the device support frame for fixation, so as to prevent the device from rotating and restrict the rotatable pipe below; After completing the above operations, hoisting can begin. After hoisting is completed, reset the enclosure 307, loosen the winding shaft 303 again, connect an appropriate number of movable counterweights 308 to the mounting bracket 1, and the device can resume use.

The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be regarded as falling within the protection scope of the present invention.
