Description

Technical Field

[0001] This invention relates to the field of concrete transportation technology, and specifically to a concrete placement system and method. Background Technology

[0002] Concrete conveying and placement have always been among the most critical aspects of construction. Traditional concrete conveying methods typically rely on manual handling or simple fixed conveying equipment, resulting in low placement accuracy, low construction efficiency, and difficulty in adapting to different terrains and pit widths. Furthermore, in the construction of deep trenches with large construction areas, traditional concrete conveying methods often fail to meet the demands, leading to longer construction times and inconsistent quality. Moreover, existing concrete placing booms are often fixed in one location during concrete conveying. When placing concrete over long distances in deep trenches, the boom needs to be moved using a crane, which is extremely inconvenient and significantly reduces work efficiency. Additionally, current technologies use conveyor belts combined with trolleys to transport concrete, moving it from the conveyor belt to the trolley and then to the placement location. This method leaves some concrete residue on the conveyor belt, which is difficult to clean. Over time, this residue corrodes the conveyor belt, affecting concrete delivery. Furthermore, during long-distance transport, significant moisture loss from the concrete affects the pouring quality.

[0003] Therefore, there is an urgent need for a concrete placement system that can prevent concrete moisture loss, efficiently transport concrete, and has an automatic cleaning function. Summary of the Invention

[0004] The purpose of this invention is to provide a concrete placement system to solve the above-mentioned problems.

[0014] Furthermore, a method of using a concrete placing system includes the following steps: Step 1: Preparation stage. Adjust the position of the two power trolley components on the conveying component I according to the width of the deep trench of the pit foundation, so that the beam frame walls on both sides of the deep trench foundation are located in the middle of the walking wheels. The construction workers drive the concrete mixer truck full of concrete to the initial position. At this time, the outlet of the discharge chute is located directly above the transport frame, thus completing the material preparation work for the deep trench foundation. Step 2: In the first feeding stage, the operator controls the hopper to open, and the concrete falls into the transport frame through the discharge chute. When the concrete in the transport frame is filled to four-fifths, the filling stops, and the feeding component II is activated in conjunction with the anti-blocking component to send the concrete in the transport frame into the guide hopper I, thus completing the conveying work of the first feeding stage. Step 3: Concrete Placement Stage in the Short-Section Deep Trench. Based on the concrete placement situation, start the conveyor motor in the forward direction. Concrete is transported via conveyor belt II to the guide hopper II at one end. This is done in conjunction with the telescopic chute for concrete placement. Depending on the concrete placement within the deep trench, stop the conveyor motor and start the drive motor on the moving guide wheel to quickly adjust the position of conveyor assembly II on conveyor assembly I. After completing the position adjustment of conveyor assembly II, stop the drive motor on the moving guide wheel and start the conveyor motor again to continue concrete placement, expanding the placement area to half the width of the deep trench, thus completing the deep trench placement. When half of the trench is being filled with concrete, the conveyor motor is reversed and started. Concrete is then transported via conveyor belt II to the guide hopper II at the other end. The concrete is then placed in conjunction with the telescopic chute. Depending on the concrete placement in the deep trench, the conveyor motor is stopped, and the drive motor on the moving guide wheel is started. The position of conveyor assembly II on conveyor assembly I is quickly adjusted. After the position adjustment of conveyor assembly II is completed, the drive motor on the moving guide wheel is stopped, and the conveyor motor is started to continue placing the concrete, thus completing the concrete placement of the other half of the deep trench and completing the concrete placement of the small section of the deep trench. Step 4: Concrete placement stage of the entire deep trench foundation. Start the concrete mixer truck and travel motor, and move the mixer truck assembly and conveyor assembly I synchronously to the top of the next small section of the deep trench foundation. Repeat Step 3 to carry out the concrete placement work, and then start the concrete mixer truck and travel motor again to move the mixer truck assembly and conveyor assembly I synchronously. Repeat the process until the concrete placement work of the entire deep trench foundation is completed. Step 4: Cleaning stage. After the fabric work is completed, the water pump on the cleaning tank is started, and the cleaning components are used to rinse and clean the transport frame, transport belt I and transport belt II to complete the cleaning work.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention uses a transport frame for the first stage of material feeding, which avoids the problem of concrete moisture evaporation caused by traditional long belt transport. Furthermore, by setting up a feeding component II with adjustable position and bidirectional material distribution, the concrete can be quickly transported to the designated location, greatly reducing the concrete transport time and improving work efficiency. 2. This invention, through the cooperation of the anti-blocking component and the feeding component II, can quickly transfer the concrete in the transport frame, speed up the material placement efficiency, and avoid concrete residue in the transport frame, which would affect subsequent conveying after solidification. In addition, the anti-blocking component, the conveyor belt II and the telescopic chute can be used to prevent stratification and segregation of concrete that has undergone long-term sedimentation, so that the concrete transported into the deep trench is in the best mixing state. 3. This invention, through the cooperation of a cleaning component, an anti-clogging component, a feeding component II, and a cleaning component, can quickly clean the conveying components that come into contact with concrete, preventing residual concrete from corroding the conveying components and avoiding the impact of residual concrete solidification on the next conveying, thus greatly improving the service life of the system.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0019] Example 1 like Figures 1 to 12As shown, a concrete placing system includes a beam frame wall and a concrete mixer truck assembly 1 arranged within a pit foundation. A power trolley assembly 2 is movably mounted on the beam frame wall. A conveying assembly I 3 is installed on the power trolley assembly 2. A conveying assembly II 4, a processing assembly 5, and a cleaning assembly 6 are installed on the conveying assembly I 3. The power trolley assembly 2 includes a traveling support 202, on which a connecting frame 204 for installing the conveying assembly I 3 is fixedly mounted. A moving assembly that contacts and connects with the beam frame wall for driving the system's movement is also installed on the traveling support 202. The conveying assembly I 3 includes a mounting frame 305 fixedly mounted on the connecting frame 204. A maintenance walkway 304 for personnel to pass through during system maintenance and a mounting bracket for assisting in the installation of the conveying assembly II 4, processing assembly 5, and cleaning assembly 6 are fixedly mounted on the mounting frame 305. The support frame 303 and the mounting frame 305 are equipped with a feeding assembly I for long-distance concrete conveying; the conveying assembly II 4 includes a mounting guide beam 405 fixedly mounted on the mounting frame 305, a movable guide wheel 401 movably mounted on the mounting guide beam 405, and a feeding assembly II for precise concrete delivery fixedly mounted on the movable guide wheel 401; the processing assembly 5 includes a mounting bracket 501 and a cleaning water tank 502 fixedly mounted on the mounting frame 305, an anti-clogging assembly for preventing concrete accumulation is mounted on the mounting bracket 501, the anti-clogging assembly is connected to the feeding assembly II in a transmission connection, and a water spraying assembly for cleaning concrete residue is mounted on the cleaning water tank 502; the cleaning assembly 6 includes a mounting plate 603 fixedly mounted on the mounting frame 305, and a cleaning assembly for sweeping concrete residue is mounted on the mounting plate 603.

[0020] The concrete mixer truck assembly 1 includes a concrete mixer truck 101 that moves with the system. The concrete mixer truck 101 is equipped with a hopper 102, and a discharge chute 103 for feeding concrete is provided below the hopper 102.

[0021] The power trolley assembly 2 includes traveling brackets 202 mounted on the beam walls on both sides of the pit foundation. Connecting frames 204 are fixedly installed on each of the two traveling brackets 202, and an installation frame 305 is fixedly mounted on each of the two connecting frames 204. The connecting frames 204 and the installation frame 305 are fastened together with bolts and nuts. The position of the two connecting frames 204 can be adjusted according to the width of the pit foundation to accommodate different widths of pit foundation materials. Two traveling wheels 203 are rotatably mounted on each of the two traveling brackets 202, and a traveling motor 20 is fixedly mounted on each of them. 1. The traveling wheels 203 on both sides of the pit foundation are respectively connected to the pit foundation beam frame wall. The traveling wheels 203 are driven by the traveling motor 201 through the transmission chain. By starting the traveling motor 201, the traveling wheels 203 are driven to rotate, which in turn drives the entire concrete placing system to move linearly on the pit foundation. When the entire concrete placing system moves, the concrete mixer truck 101 moves together to achieve continuous concrete placing. The position of the power trolley component 2 can be adjusted on the mounting frame 305 according to the width of the pit foundation deep trench to adapt to the concrete placing of pit foundation deep trenches of different widths.

[0022] The conveying assembly I3 includes a mounting frame 305 fixedly installed on the connecting frame 204. The mounting frame 305 is fixedly installed with a maintenance walkway 304 for personnel passage during system maintenance, and a support bracket 303 for assisting in the installation of the conveying assembly II4, processing assembly 5, and cleaning assembly 6. The maintenance walkway 304 is equipped with an operation panel (not shown in the figure) for operating the entire system. The mounting frame 305 is equipped with a feeding assembly I for long-distance concrete conveying. The feeding assembly I includes a transport frame 301, a transport belt I 302, a transport support bracket I 306, a rotating roller I 307, a guide wheel frame I 308, an auxiliary baffle 309, a deflection rod 310, a guide hopper I 311, and a guide rail 312. The transport support bracket I 306 is fixedly installed on... On the mounting frame 305, the transport support I 306 includes a first inclined section, a gentle section, and a second inclined section. The first inclined section, the gentle section, and the second inclined section together constitute the first feeding section. The horizontal length of the first feeding section is adjusted according to the width of the deep trench, so that the horizontal length of the first feeding section is always kept at half the width of the deep trench. Correspondingly, when the width of the deep trench varies greatly, the total length of the mounting frame 305 is adaptively adjusted according to the width of the deep trench to accommodate material distribution in deep trenches of different widths. A rotating roller I 307 is rotatably installed at the end of the first inclined section, and a guide hopper I 311 is fixedly installed at the end of the second inclined section. The outlet of the guide hopper I 311 is smaller than the inlet, controlling the output of concrete in the guide hopper I 311.

[0023] A rotating roller I307 is rotatably mounted on the guide hopper I311. A drive motor for rotating the rotating roller I307 is fixedly mounted on the rotating shaft of the rotating roller I307 on the guide hopper I311. The rotating roller I307 in the first inclined section and the rotating roller I307 on the guide hopper I311 are belt driven by a conveyor belt I302. The length of the conveyor belt I302 is adaptively adjusted according to the width of the deep trench of the pit foundation. A transport frame 301 is fixedly mounted on the transport belt I302 to assist in transporting concrete. The transport belt I302 is provided with square grooves. The grooves of the transport belt I302 are made of plastic material and can bend along with the transport belt I302 when it is rolled up. The transport frame 301... Two-thirds of the guide wheel frame 1 is fixedly installed with the square groove of conveyor belt I302, while the remaining one-third is slidably installed with the square groove of conveyor belt I302. The square groove prevents concrete leakage during the first feeding section. Multiple guide wheel frames I308 are provided (the number is set according to requirements). Multiple guide wheel frames I308 are linearly arrayed on the transport support I306 to assist in the smooth transport of the transport frame 301 on the conveyor belt I302. The guide wheel frames I308 support the conveyor belt I302 to ensure that the transport frame 301 does not collapse due to excessive weight when it passes, thus affecting the overall transport. At the same time, they tension the conveyor belt I302 to ensure... There will be no slippage affecting the conveying process. Auxiliary baffles 309 are rotatably mounted on the transport frame 301 to assist in loading concrete. Two auxiliary baffles 309 are provided and symmetrically arranged. In the initial position, the two auxiliary baffles 309 are closed to form a gate, preventing concrete leakage in the first feeding section. Deflection rods 310 are fixedly installed on the rotating shafts of the two auxiliary baffles 309. Two guide rails 312 are provided and fixedly installed on both sides of the guide hopper I 311, cooperating with the deflection rods 310 to assist in the opening and closing of the auxiliary baffles 309. When the conveyor belt I 302 moves the transport frame 301, it moves the deflection rods 310, which in turn move the guide rails 312. At point 2, the guide rail 312 forms a track that presses the deflection rod 310, causing it to deflect. This, in turn, causes the auxiliary baffle 309 to deflect, opening both auxiliary baffles 309. At this time, one-third of the transport frame 301 moves out of the transport belt I 302 (this section is slidably installed with the square groove of the transport belt I 302). The bottom of the moved-out part of the transport frame 301 and the opened auxiliary baffle 309 send the concrete into the guide hopper I 311. At the same time, the processing component 5 pushes the concrete in the transport frame 301 and continuously taps the transport frame 301 to ensure that all the concrete in the transport frame 301 is sent into the guide hopper I 311, completing the concrete conveying of the first feeding section.

[0024] During operation, the first feeding section is achieved through feeding component I. During the first feeding section, worker 1 uses concrete mixer truck 101 to deliver concrete above transport frame 301. Concrete is then intermittently fed into transport frame 301 via hopper 102 and discharge chute 103. When transport frame 301 is filled to four-fifths full, hopper 102 stops feeding. Worker 2 then controls the drive motor on rotating roller I 307 via the control panel on maintenance walkway 304, moving transport frame 301 towards guide hopper I 311. When it reaches guide hopper I 311, one-third of transport frame 301 is aligned with conveyor belt I 302. The gap formed by the separation and the opening of the auxiliary baffle 309 constitute the feeding port. The concrete in the transport frame 301 falls into the guide hopper I 311 from the feeding port. In order to ensure that the concrete in the transport frame 301 is completely discharged, the second inclined section of the transport support I 306 makes the transport frame 301 tilted when it is discharged. In conjunction with the processing component 5, the transport frame 301 is continuously vibrated and the concrete in the transport frame 301 is pushed, thereby completing the concrete conveying work of the first feeding section. After completion, the drive motor on the rotating roller I 307 reverses and drives the transport frame 301 to reset, thereby repeating the above process to achieve continuous concrete feeding.

[0025] The conveying assembly II 4 includes two mounting guide beams 405 fixedly mounted on the mounting frame 305. The length of the two mounting guide beams 405 is the same as the distance between the two traveling supports 202. Two movable guide wheels 401 are rolled on the mounting grooves of the two mounting guide beams 405 respectively. A drive motor for driving the movable guide wheels 401 to move on the mounting guide beams 405 is mounted on the two movable guide wheels 401 on one side of the mounting guide beam 405. A feeding assembly II for precise concrete delivery is fixedly mounted on the four movable guide wheels 401. The feeding assembly II includes a conveying... The components include a conveyor support II 402, a conveyor belt II 403, a transmission rack 404, a transport motor 406, a guide wheel frame II 407, a wire feeding motor 408, a telescopic chute 409, a wire wheel 410, a guide hopper II 411, and a rotating roller II 412. The conveyor support II 402 is equipped with one movable guide wheel 401 and is movably installed with the installation guide beam 405. The length of the conveyor support II 402 is less than half the width of the deep trench of the pit foundation (to ensure that when the two telescopic chutes 409 are combined, concrete can be placed at any position above the deep trench of the pit foundation).

[0026] Two guide hoppers II411 are provided, each fixedly installed at one end of the transport support II402. Rotating rollers II412 are rotatably mounted on each guide hopper II411 at both ends of the transport support II402. The two rotating rollers II412 are driven by the transport belt II403. A transport motor 406 is fixedly installed on one end of the guide hopper II411 to drive the transport belt II403. The output shaft of the transport motor 406 is fixedly installed on the rotating rollers II412 on that end of the guide hopper II411. Multiple guide wheel frames II407 are provided (the number is set according to requirements). Multiple guide wheel frames II407 are fixedly linearly arrayed on the transport support II402 to assist the transport belt II403 in smoothly conveying concrete. The guide wheel frames II407 support the transport belt II403 to ensure that the transport belt II403 does not collapse due to excessive weight when the concrete is conveyed, thus affecting the overall conveying process. The conveyor belt II 403 is tensioned to ensure that slippage does not affect the conveying. The transmission rack 404 is fixedly installed on the conveyor belt II 403. The transmission rack 404 is made of plastic material and can adapt to the bending of the conveyor belt II 403 when it enters the rotating roller II 412. The transmission rack 404 meshes with the transmission gear on the transmission shaft II 508 to drive the anti-blocking component on the processing assembly 5. The isolation plate is fixedly installed on the conveyor belt II 403. The isolation plate is set on both sides of the conveyor belt II 403 (inside the transmission rack 404). The isolation plate is made of flexible material to prevent concrete from scattering. The feed hopper II 411 at both ends of the transport support II 402 is fixedly installed with a wire feeding motor 408 and a telescopic chute 409. The output shaft of the wire feeding motor 408 is fixedly installed with a wire pulley 410. The traction rope is fixedly installed on the wire pulley 410. The traction rope of the wire pulley 410 passes through the telescopic chute 409 to drive the telescopic chute 409 to extend and retract to assist in the precise feeding of concrete.

[0027] During operation, the concrete conveyed from the first feeding section falls from the outlet of the guide hopper I 311 onto the conveyor belt II 403. When concrete is fed into the guide hopper I 311 from the conveyor frame 301, the conveyor motor 406 is started, driving the rotating roller II 412 to rotate, which in turn moves the concrete on the conveyor belt II 403. The moving transmission rack 404 drives the transmission shaft II 508 to rotate, which in turn activates the anti-blocking component, ensuring that the concrete in the conveyor frame 301 completely falls into the guide hopper I 311 and then onto the conveyor belt II 403. When starting the conveyor motor 406, it first rotates clockwise, causing the conveyor belt II... The concrete on 403 moves to the guide hopper II 411, which is farther from the concrete mixer truck 101. The concrete in guide hopper II 411 is then fed into the deep trench of the pit foundation via the telescopic chute 409. To prevent segregation of the concrete due to excessive depth of the trench, the telescopic chute 409 is extended by starting the feeder motor 408. This ensures that the concrete will not segregate due to excessive drop, affecting the pouring effect. The concrete is then distributed through guide hopper II 411 at this end. The distribution position of guide hopper II 411 is set as the distribution point, and each distribution point is distributed for an appropriate time (adjusted according to the depth of the trench to ensure the concrete distribution is optimal). (For sufficient concrete placement), after completing the placement at one point, the position of guide hopper II 411 needs to be adjusted before moving to the next placement point. During this movement, to ensure the safe meshing of the gears on 404 and 508, the transport motor 406 is turned off, and the drive motor on the moving guide wheel 401 is started. This drives the transport bracket II 402 to move on the mounting guide beam 405, which in turn drives the guide hopper II 411 at this end to move. After the movement is completed, the drive motor on the moving guide wheel 401 is turned off, and the transport motor 406 is started to continue placing concrete. The above adjustment steps are repeated so that the placement point range of the guide hopper II 411 at this end can reach the depth of the pit foundation. The concrete is laid in half of the trench width, completing the concrete placement work for one half of the deep trench foundation. After completing the placement work for one half, the transport motor 406 reverses, driving the concrete on the transport belt II 403 to the guide hopper II 411 at the other end. This, in conjunction with the telescopic chute 409, lays the concrete for the other half of the deep trench foundation, completing the conveying work of the second feeding section. This completes the concrete placement work for this section of the deep trench foundation. After completion, the concrete mixer truck 101 moves to the next placement section. The power trolley assembly 2 drives the entire system to move to the next placement section along with the concrete mixer truck 101, repeating the above process to achieve the concrete placement work for the entire deep trench foundation.

[0028] Example 2 like Figure 8 , Figure 9 and 12As shown, in this embodiment, to ensure smooth concrete transport, a processing component 5 for accelerating concrete movement and a cleaning component 6 for cleaning the transport parts are provided. The processing component 5 includes a mounting bracket 501 fixedly mounted on the mounting frame 305 and a cleaning water tank 502. Two mounting brackets 501 are provided, respectively mounted on both sides of the guide hopper I 311. The components mounted on the two mounting brackets 501 are identical. Anti-clogging components for preventing concrete accumulation are installed on the mounting brackets 501. A drive roller is rotatably mounted on both mounting brackets 501. The cleaning water tank 502 is equipped with... A water spray assembly for cleaning concrete residue includes an anti-clogging component comprising a deflection mounting bracket 503, a pusher impeller 506, drive shaft I 507, drive shaft II 508, a vibrating rod 510, and drive shaft III 511. Drive shaft I 507 is rotatably mounted on the mounting bracket 501. A drive wheel and a drive roller are fixedly mounted on drive shaft I 507. The drive roller on drive shaft I 507 and the drive roller on the mounting bracket 501 are belt-driven via a drive belt 509. Multiple protrusions are evenly spaced on the drive belt 509. A gear and a drive wheel are fixedly mounted on drive shaft II 508. The gear on drive shaft II 508 meshes with a drive rack 404. The drive wheel on drive shaft II 508 and the drive wheel on drive shaft I 507 are connected by a drive belt. Vibrating rod 510 is slidably mounted on mounting bracket 501. A spring is fixedly mounted on vibrating rod 510, with one end fixed to the vibrating rod 510 and the other end fixed to mounting bracket 501. A protrusion on drive belt 509 intermittently contacts vibrating rod 510 to continuously strike guide hopper I 311. Drive shaft III 511 is rotatably mounted on mounting bracket 501. A drive wheel and a drive gear are fixedly mounted on drive shaft III 511. The drive wheel on drive shaft III 511 connects with the drive wheel on drive shaft I 507. The drive wheel on 507 is driven by a drive belt. The deflection mounting bracket 503 is connected to the mounting bracket 303 by a torsion spring. The deflection mounting bracket 503 includes a deflection mounting seat, a mounting support bar, and a pusher bracket. The deflection mounting seat of the deflection mounting bracket 503 is connected to the mounting bracket 303 by a torsion spring. The pusher impeller 506 is rotatably mounted on the mounting support bar of the deflection mounting bracket 503 to prevent concrete from stagnating. A drive gear is fixedly mounted on the rotating shaft of the pusher impeller 506. The drive gear on the pusher impeller 506 intermittently meshes with the drive gear on the drive shaft Ⅲ 511. The pusher bracket of the deflection mounting bracket 503 intermittently contacts the transport frame 301.

[0029] The water spray assembly includes a water supply pipe 504 and a water spray head 505. The water supply pipe 504 is fixedly installed on the mounting support of the deflection mounting bracket 503. The water spray head 505 is fixedly installed on the mounting support of the deflection mounting bracket 503 to assist in cleaning the feeding assembly I. The water spray head 505 is connected to the cleaning water tank 502 through the deflection mounting bracket 503. The deflection mounting bracket 503 is made of flexible material to prevent it from falling off during deflection. The cleaning water tank 502 is equipped with a water pump for pressurizing water spraying.

[0030] During operation, in the first feeding section, the transport frame 301 moves above the guide hopper I 311, pushing the push bracket of the deflection mounting bracket 503 to deflect it. This causes the transmission gear on the drive shaft III 511 to mesh with the transmission gear on the pusher impeller 506. The drive shaft II 508 rotates under the push of the moving transmission rack 404, which in turn drives the drive shaft I 507 to rotate. This, in turn, causes the protrusions on the transmission belt 509 to intermittently impact the vibrating rod 510. Driven by a spring, the vibrating rod 510 continuously reciprocates, striking and vibrating the transport frame 301 to help the concrete in the transport frame 301 enter the guide hopper I 311. The rotation of the drive shaft I 507 simultaneously drives the drive shaft III 511 to rotate, which in turn drives the pusher impeller 506 to rotate. The rotation of the pusher impeller 506 agitates the concrete in the transport frame 301, helping the concrete in the transport frame 301 to quickly enter the guide hopper I 311, completing the first feeding stage. In the conveying process, after the concrete placement is completed, to prevent concrete residue from solidifying on the transport frame 301, conveyor belt I 302, and conveyor belt II 403, the drive motor on the rotating roller I 307 is activated to move the transport frame 301 above the guide hopper I 311. Water is then supplied to the spray nozzle 505 by the water pump on the cleaning water tank 502 to rinse the transport frame 301 and conveyor belt I 302. The rinsed mixture then passes through the guide hopper I 311, rinsing the guide hopper I 311 as well. The mixture falls onto conveyor belt II 403, which continues to move under the action of conveyor motor 406, carrying the mixture to the guide hopper II 411 equipped with cleaning component 6. The cleaning component 6 is activated to clean the conveyor belt II 403, causing the mixture to fall into the guide hopper II 411 and carry the residue in the guide hopper II 411 out through the telescopic chute 409, thus completing the cleaning work of conveyor frame 301, conveyor belt I 302 and conveyor belt II 403.

[0031] The cleaning assembly 6 includes a mounting plate 603 on which a cleaning component for cleaning concrete residue is mounted. The cleaning component includes a telescopic electric cylinder 601, a guide rod 602, a mounting base 604, a cleaning motor 605, and a cleaning wheel 606. The telescopic electric cylinder 601 is fixedly mounted on the mounting plate 603, the mounting base 604 is fixedly mounted on the extended end of the telescopic electric cylinder 601, the guide rod 602 is fixedly mounted on the mounting base 604 and slidably mounted with the mounting plate 603, the cleaning motor 605 is fixedly mounted on the mounting base 604, and the cleaning wheel 606 is rotatably mounted on the mounting base 604 and fixedly mounted with the output shaft of the cleaning motor 605 for cleaning the conveyor belt II 403.

[0032] When the system needs to be cleaned during operation, the telescopic electric cylinder 601 is activated to drive the mounting base 604 into the guide hopper II 411. The cleaning motor 605 is activated to drive the cleaning wheel 606 to rotate and clean the conveyor belt II 403, so that the mixture on the conveyor belt II 403 falls into the telescopic chute 409 and is discharged. This, in conjunction with the cleaning components, completes the cleaning work of the system, preventing concrete residue from solidifying on the transport frame 301, conveyor belt I 302 and conveyor belt II 403, causing corrosion and affecting the concrete delivery.

[0033] Example 3 A method for using a concrete placing system includes the following steps: Step 1: Preparation stage. Adjust the position of the two power trolley components 2 on the conveying component I3 according to the width of the deep trench of the pit foundation, so that the beam frame walls on both sides of the deep trench foundation are located in the middle of the walking wheel 203. The construction workers drive the concrete mixer truck 101 filled with concrete to the initial position. At this time, the outlet of the discharge chute 103 is located directly above the transport frame 301, thus completing the material preparation work for the deep trench foundation. Step 2: In the first feeding stage, the operator controls the hopper 102 to open, and the concrete falls into the transport frame 301 through the discharge chute 103. When the concrete in the transport frame 301 is filled to four-fifths, the filling stops, and the feeding component II is activated in conjunction with the anti-blocking component to send the concrete in the transport frame 301 into the guide hopper I 311, thereby completing the conveying work of the first feeding stage. Step 3: Concrete placement stage in the short-section deep trench. Based on the placement situation, start the conveyor motor 406 in the forward direction. Concrete is transported via conveyor belt II 403 to the guide hopper II 411 at one end. This works in conjunction with the telescopic chute 409 for concrete placement. Depending on the placement situation in the deep trench, stop the conveyor motor 406 and start the drive motor on the moving guide wheel 401 to quickly adjust the position of the conveyor assembly II 4 on the conveyor assembly I 3. After adjusting the position of the conveyor assembly II 4, stop the drive motor on the moving guide wheel 401 and start the conveyor motor 406 to continue placement, expanding the placement area to half the width of the deep trench, thus completing the deep trench placement. When half of the trench is being filled with concrete, the transport motor 406 is reversed and started. Concrete is then transported via the conveyor belt II 403 to the guide hopper II 411 at the other end. The telescopic chute 409 is used to carry out the concrete filling. Depending on the filling situation in the deep trench, the transport motor 406 is stopped, and the drive motor on the moving guide wheel 401 is started to quickly adjust the position of the conveyor component II 4 on the conveyor component I 3. After the position adjustment of the conveyor component II 4 is completed, the drive motor on the moving guide wheel 401 is stopped, and the transport motor 406 is started to continue filling, thus completing the concrete filling work for the other half of the deep trench and completing the concrete filling of the small section of the deep trench. Step 4: Concrete placement stage of the entire deep trench foundation. Start the concrete mixer truck 101 and the travel motor 201, and move the mixer truck assembly 1 and the conveyor assembly I3 synchronously to the top of the next small section of the deep trench foundation. Repeat Step 3 to carry out the concrete placement work, and then start the concrete mixer truck 101 and the travel motor 201 to move the mixer truck assembly 1 and the conveyor assembly I3 synchronously. Repeat the process until the concrete placement work of the entire deep trench foundation is completed. Step 5: Cleaning stage. After the material placement is completed, the water pump on the cleaning water tank 502 is started, and the cleaning component 6 is used to wash and clean the transport frame 301, transport belt I 302 and transport belt II 403. The cleaning work is completed to prevent concrete residue from solidifying and corroding the transport frame 301, transport belt I 302 and transport belt II 403, and to extend the service life of the equipment.
