Description

Technical Field

[0001] The invention relates to the technical field of building material transmission, in particular to a building engineering loading device. Background Art

[0002] Concrete pump, also known as concrete pump, consists of a pump body and a delivery pipe. It is a machine that uses pressure to continuously deliver concrete along a pipeline. It is mainly used in building construction, bridge and tunnel construction. It is mainly divided into gate valve concrete pump and S valve concrete pump. Another type is to install the pump body on the chassis of a car and equip it with a retractable or tortuous placing boom to form a pump truck.

[0003] The Chinese patent discloses a construction engineering feeding device (publication number CN118361104A), including a feeding pipe. The beneficial effect of the invention is that by setting an inner and outer double-layer paddle structure inside the feeding pipe, the inner and outer paddles can be rotated forward and backward through the cooperation of gears and tooth grooves, so as to effectively transport concrete. During the transportation process, the inner paddle pushes the concrete upward through rotation and sends it into the feeding pipe through the discharge port, while the outer paddle can keep the concrete from solidifying in the pipe when the transportation stops, and returns the concrete to the hopper tank by reversing, playing the role of stirring and circulating transportation. In order to realize the forward and reverse rotation and synchronous rotation of the paddle, the device is equipped with motors, gears, rotating support rods and balls, etc. The motor is controlled to slide on the fixed rod platform through an electric push rod, and then the meshing state of the gear and the tooth grooves on the inner and outer paddles is adjusted to achieve the effect of different rotation modes.

When the hydraulic telescopic rod 201 is extended, the cement in the cement cylinder 209 is squeezed and pushed into the transmission pipe 202, thereby making the transfer of concrete more convenient.

[0038] See also Figures 1 to 5 The stirring mechanism 3 includes a stirring rod 301. A rotating rod 302 is rotatably mounted on the inner wall of the cement box 101, and the stirring rod 301 array is mounted on the outer wall of the rotating rod 302.

When the hydraulic telescopic rod 201 pushes When the piston ring 203 moves, the pulling rope 304 starts to move, and the pulling rope 304 pulls the pulling ring 303 to start rotating, so that the rotating rod 302 drives the stirring rod 301 to start rotating, and the end of the cement cylinder 209 close to the pulling rope 304 is rotated and installed with a guide wheel 305, and the pulling rope 304 is wound on the outer wall of the guide wheel 305, and the guide wheel 305 changes the moving direction of the pulling rope 304, so that the pulling rope 304 pulls the pulling ring 303 to rotate more conveniently, and the pulling ring 30 3 is provided with a plurality of limit grooves 306, and the outer wall of the rotating rod 302 near the limit grooves 306 is provided with mounting grooves 307 that match the limit grooves 306, and the inner wall of the mounting grooves 307 is slidably installed with a limit block 308, and a limit spring 309 is fixedly installed between the limit block 308 and the mounting grooves 307. The limit block 308 and the limit groove 306 arranged between the pulling ring 303 and the rotating rod 302 enable the pulling rope 304 to pull the rotating rod 302 to rotate. After that, when the pulling circle 303 rotates in the opposite direction, the pulling circle 303 pushes the limit block 308 to shrink into the installation groove 307, and a winding spring 310 is fixedly installed between the pulling circle 303 and the rotating rod 302, so that the pulling rope 304 no longer pulls the pulling circle 303 to rotate, and the winding spring 310 pushes the pulling circle 303 to start rotating, and winds the pulling rope 304 on the outer wall of the pulling circle 303, and circulates in sequence, so that the rotating rod 302 drives the stirring rod 301 to rotate clockwise all the time.

[0039] See also Figures 1 to 7The protection mechanism 4 includes a fixed rod 401, and the fixed rod 401 is fixedly installed on the upper end of the installation box 102. The fixing rod 401 is rotatably installed on the outer wall of the installation box 102, and the mounting rod 402 is fixedly installed on the end of the mounting rod 402 away from the installation box 102. The mounting frame 403 is fixedly installed on the end of the mounting frame 403 away from the mounting rod 402. The mounting cylinder 404 is fixedly installed on the inner wall of the mounting cylinder 404. A switching cylinder 405 is rotatably installed, and a through hole is opened at the side end of the above-mentioned switching cylinder 405. When the switching cylinder 405 starts to rotate, the through hole for passing the material on the switching cylinder 405 rotates to fit with the inner wall of the mounting cylinder 404, thereby closing the mounting cylinder 404 and preventing cement from passing through the mounting cylinder 404.

[0040] See also Figures 1 to 8 The side end of the installation cylinder 404 away from the installation box 102 is fixedly installed with an installation ring 406, and the end of the installation ring 406 away from the installation cylinder 404 is rotatably installed with a connecting pipe 407, and the end of the connecting pipe 407 away from the mounting frame 403 is rotatably installed with a connecting ring 408, and the center position of the connecting ring 408 and the fixing rod 401 is on the same center line, so that when the installation cylinder 404 swings, the installation rod 402 and the connecting pipe 407 rotate, but the fixing rod 401 and the connecting ring 408 remain stable, and the transmission tube 20 The connecting ring 408 is rotatably mounted on one end away from the connecting pipe 407, and the connecting ring 408 is fixedly mounted on the inner wall of the cement box 101. The end of the mounting cylinder 404 away from the mounting ring 406 is fixedly mounted with a material passing ring 409. After the material passing ring 409 moves to one end of the cement cylinder 209, the hydraulic telescopic rod 201 extends, and the piston ring 203 squeezes and moves the concrete in the cement cylinder 209, and transmits it to the connecting pipe 407 through the material passing cylinder and the switching cylinder 405, and then transmits it to the material transfer pipe through the connecting pipe 407.

[0041] See also Figures 1 to 8 , the side ends of the installation box 102 are symmetrically installed with installation plates 410, and the side ends of the installation plates 410 close to the installation cylinder 404 are rotatably installed with pushing telescopic rods 411, and the end of the pushing telescopic rod 411 away from the installation rod 402 is fixedly installed with a sliding rod 412, and the outer wall of the installation cylinder 404 close to the sliding rod 412 is fixedly installed with a sliding frame 413, and the sliding rod 412 is slidably installed on the inner wall of the sliding frame 413. When the pushing telescopic rod 411 starts to work, the pushing telescopic rod 411 pushes the sliding rod 412 to slide on the sliding frame 413 for a certain distance, and then the pushing telescopic rod 411 pushes the installation cylinder 404 to start rotating.

[0042] See also Figures 1 to 8A fixed gear 414 is fixedly installed on one end of the fixed rod 401 near the switching cylinder 405, and a rotating gear 415 is fixedly installed on the upper end of the switching cylinder 405, and the fixed gear 414 is meshed with the rotating gear 415. When the mounting cylinder 404 starts to rotate around the mounting rod 402, the rotating gear 415 starts to rotate around the fixed gear 414, so that the rotating gear 415 drives the switching cylinder 405 to start rotating. A protective cover 416 is fixedly installed on the upper end of the mounting cylinder 404 near the gear, and the protective cover 416 covers the fixed gear 414. The fixed gear 414 and the rotating gear 415 are protected to prevent cement from moving to the meshing position of the fixed gear 414 and the rotating gear 415, causing gear damage. A one-way bearing 417 is fixedly installed at the lower end of the switching cylinder 405. The one-way bearing 417 is a prior art and will not be described in detail here. A control ring 418 is fixedly installed on the outer wall of the one-way bearing 417, and a return spring 419 is fixedly installed between the control ring 418 and the switching cylinder 405. A control rope 420 is wound around the outer wall of the control ring 418. When the return spring 419 makes the control rope 420 no longer pull the control ring 418, it is more convenient to push the control ring 418 to wind the control rope 420 around the outer wall of the control ring 418, and the control rope 420 is fixedly installed on the end of the sliding rod 412 away from the pushing telescopic rod 411. When the pushing telescopic rod 411 starts to shrink, the pushing telescopic rod 411 pulls the sliding rod 412 to slide on the sliding frame 413, so that the control rope 420 pulls the control ring 418 to start rotating, and the control ring 418 drives the switching cylinder 405 After starting to rotate 90 degrees, the sliding rod 412 contacts the sliding frame 413, pushing the telescopic rod 411 to continue to contract, and the sliding frame 413 is pulled by the sliding rod 412 to start moving, so that the installation cylinder 404 starts to rotate and move to the opening of another cement cylinder 209, and during the movement, the switching cylinder 405 continues to rotate. When it moves to the opening of the cement cylinder 209, the switching cylinder 405 just rotates 180 degrees, so that the through hole set in the switching cylinder 405 is connected with the installation ring 406 and the material passing ring 409.

[0043] The working principle of the present invention is: when a concrete pump is used to transport concrete in a construction project, the rotating motor 206 is started, the driving gear 207 and the driven gear 208 start to rotate, the support plate 204 rotates the support frame 203 to a suitable angle, the transmission frame 205 is started, the transmission frame 205 is unfolded, and the output end of the transmission pipe 202 is placed at the position where cement needs to be poured on the floor, so that the direction and position of cement pouring can be adjusted more flexibly;

[0044] Start the hydraulic telescopic rod 201. When the hydraulic telescopic rod 201 is contracting, the hydraulic telescopic rod 201 pushes the piston ring 203 to start moving, and the pulling rope 304 pulls the pulling ring 303 to start rotating. The pulling ring 303 drives the rotating rod 302 to rotate, and the symmetrically installed hydraulic telescopic rod 201 switches back and forth to keep the pulling ring 303 rotating. The rotating rod 302 makes the stirring rod 301 stir the cement in the cement box 101 all the time to prevent the cement in the cement box 101 from settling, resulting in the cement entering the transmission pipe 202 being not uniform.

[0045] At the same time, the hydraulic telescopic rod 201 pushes the piston ring 203 to move the cement sucked in the cement cylinder 209, and transfers it to the connecting pipe 407 through the material passing ring 409, the switching cylinder 405 and the installation ring 406, and then transfers it to the material transfer pipe through the connecting ring 408. When the cement in the cement cylinder 209 is pushed out, the telescopic rod 411 is started to push the telescopic rod 411 to move the sliding rod 412 on the sliding frame 413, and the sliding rod 412 drives the control rope 420 to move, and the control rope 420 pulls the control ring 418 to rotate, so that the switching cylinder 405 rotates 90 degrees to make the installation cylinder 404 is closed, pushing the telescopic rod 411 to continue working, so that the sliding rod 412 pulls the sliding frame 413 to start moving, and the installation cylinder 404 rotates, so that the installation cylinder 404 moves to another cement cylinder 209, and during the movement, the rotating gear 415 drives the switching cylinder 405 to continue to rotate 90 degrees, so that the through hole set in the switching cylinder 405 is connected with the installation ring 406 and the material passing ring 409, thereby preventing the cement in the transmission pipe 202 of the concrete delivery pump from flowing back under the action of gravity during the switching process, resulting in an increase in the reflux of cement when the cement is transmitted to a higher position, resulting in a lower cement transmission efficiency.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
