Description

Technical Field

[0001] This application relates to the technical field of concrete discharge auxiliary components, and in particular to a mobile concrete conveying device. Background Technology

[0002] In civil engineering projects such as bridges, foundations, and retaining walls, the delivery and pouring of ready-mixed concrete is a core element determining the structural strength, construction efficiency, and safety of the project. Ready-mixed concrete needs to be delivered precisely and efficiently from the mixer truck to the pouring point, and the continuity, lack of spillage, and low loss of this delivery process directly affect the project progress. Currently, there are two main types of conveying methods for ready-mixed concrete. However, they have significant shortcomings in adapting to different engineering scenarios and cost control, making it difficult to meet the needs of high efficiency, economy, and flexibility. The conveying method of the tanker truck with its own chute is the most commonly used method for small and medium-sized projects and scattered pouring points. The principle is to guide the concrete directly to the pouring point through the retractable chute below the unloading port of the tanker truck, or to first unload it into a wheelbarrow and then transfer it to the target location manually or mechanically. Regarding the aforementioned technologies, the inventors discovered that the slump of concrete is a core indicator for measuring its fluidity and workability, directly determining the density and structural strength of the concrete after pouring. According to concrete quality control standards, the slump of ready-mixed concrete must be tested before pouring. Traditional slump testing uses a random sampling method. Sampling requires interrupting the pouring and material delivery process, which is inefficient. Interruptions can easily cause cold joints in the concrete, requiring additional treatment, increasing the construction period and cost. At the same time, random sampling in slump testing leads to bias and low accuracy. There are spatial differences between the sampling point and the actual pouring point. During the transportation process, the slump may change due to water evaporation and aggregate settlement, resulting in test results that cannot accurately reflect the state of the concrete at the pouring point. Utility Model Content

[0003] To overcome the limitations of existing concrete slump testing methods, which are crucial for measuring the fluidity and workability of concrete and directly determine its density and structural strength after pouring, concrete quality control standards require slump testing before pouring ready-mixed concrete. Traditional slump testing employs random sampling, which interrupts the pouring and material delivery process, resulting in low efficiency and the potential for cold joints requiring additional treatment, thus increasing construction time and costs. Furthermore, random sampling in slump testing leads to bias and low accuracy, and spatial differences exist between sampling points and actual pouring points. During transport, concrete slump may change due to moisture evaporation and aggregate settlement, causing the test results to fail to accurately reflect the concrete condition at the pouring point. Therefore, this application provides a mobile concrete delivery device.

[0004] The mobile concrete conveying device provided in this application adopts the following technical solution: A mobile concrete conveying device includes a support component, a conveying cylinder, and a detection component. The support component includes a support frame, on which two brackets are symmetrically and vertically fixed on the top surface. The top of the two brackets of the support frame is connected to and assembled with the conveying cylinder. A receiving hopper is vertically connected and fixed to the upper part of the outer circumference of the conveying cylinder, and a detection screw tube is vertically connected and fixed to the bottom of the outer circumference of the conveying cylinder. The bottom end of the detection screw tube is assembled and connected with the detection component. One side of the outer circumference of the detection screw tube is open, and a gate is slidably inserted into the opening of the detection screw tube. The detection component includes a slump detection cylinder, on which a threaded ring is vertically connected and fixed to the top of the slump detection cylinder, and the threaded ring is threadedly connected to the detection screw tube. The bottom end of the slump detection cylinder is open, and a base plate is detachably assembled to the bottom end of the slump detection cylinder.

[0005] By adopting the above technical solution, the support frame of the support component provides stable support for the entire device, and the bracket is used to securely install the guide cylinder. The guide cylinder is mainly used to transport concrete. Its upper receiving hopper can effectively guide the concrete into the guide cylinder, while the bottom detection solenoid is used to collect concrete samples. The gate can close the detection solenoid when needed to facilitate testing. The slump detection cylinder in the testing component is used to detect the slump of the concrete. The threaded ring allows it to be reliably connected to the detection solenoid, and the base plate can be installed to close the slump detection cylinder after testing. Concrete enters the guide cylinder through the receiving hopper, then reaches the detection solenoid and is partially stored. By rotating the threaded ring to connect the slump detection cylinder and the detection solenoid, concrete samples are collected into the slump detection cylinder. Subsequently, the detection hole is exposed by moving the gate, allowing personnel to observe or take samples for slump testing. After testing, the base plate is replaced to close the slump detection cylinder.

[0006] Optionally, a pull bar is horizontally fixed on the outer wall of the gate, and a return spring is horizontally fixed at the end of the pull bar, with the other end of the return spring fixed on the outer circumference of the detection solenoid.

[0007] By adopting the above technical solution, the gate's function is to control the flow of fluid. A horizontally fixed pull rod is attached to its outer wall, connecting the gate and the return spring to ensure the gate can promptly return to its initial position upon detecting an abnormality. The return spring is connected to the pull rod and fixed to the outer circumference of the detection solenoid. When the gate deviates from its normal position during flow detection, the return spring provides a restoring force, causing the gate to quickly return to its initial position, thus ensuring the normal operation of the system. During this process, the detection solenoid detects the fluid flow status. Once an abnormality is detected, the pull rod and return spring will cause the gate to close or adjust promptly, achieving effective control and protection of the fluid flow.

[0008] Optionally, screws are vertically rotatably connected to the lower side of the outer wall of the slump test cylinder, and screw seats are horizontally fixed to the outside of the base plate, with the screws and screw seats being threadedly assembled and connected.

[0009] By adopting the above technical solution, the main function of the slump test cylinder is to provide a standard measurement space during the concrete slump testing process, ensuring the accuracy and consistency of the test. The screws are designed to lock the mounting base plate at the bottom of the slump test cylinder, sealing the bottom end.

[0010] Optionally, lugs are horizontally fixed on both sides of the outer circumference of the feed tube, and locking bolts are installed through the vertical threads on the lugs.

[0011] By adopting the above technical solution, lugs are horizontally fixed on both sides of the outer circumference of the guide cylinder. The lugs are provided with vertical threaded holes, and the position of the guide cylinder can be precisely adjusted and fixed by locking bolts.

[0012] Optionally, a screw groove is vertically provided on the top surface of the bracket, and the screw groove on the bracket is threadedly connected to the locking bolt.

[0013] By adopting the above technical solution, the top surface of the bracket is provided with a screw groove for inserting locking bolts. By adjusting the depth of the locking bolts screwed into the screw grooves, the guide cylinder can be accurately fixed, ensuring its stability during operation.

[0014] Optionally, wheels are rotatably connected to both sides of the bottom surface of the support frame, and swivels are symmetrically and vertically fixed at both ends of the bottom surface of the support frame.

[0015] By adopting the above technical solution, the support frame is mainly used to bear and support the entire device. Wheels are mounted on both sides of its bottom surface via a rotatable connection, ensuring that the device can move easily horizontally. Rotary seats are mounted at both ends of the bottom surface of the support frame for fixing the rotating rods.

[0016] Optionally, a rotating rod is horizontally rotatably connected to both ends of the bottom surface of the support frame, and a screw is vertically fixed in the middle of the rotating rod.

[0017] By adopting the above technical solution, a screw is vertically fixed in the middle of the rotating rod, and the screw is vertically threaded inside the supporting screw tube, so that the supporting screw tube can move up and down.

[0018] Optionally, a support screw tube is assembled on the screw with vertical threads, and a stop is rotatably connected to the bottom end of the support screw tube.

[0019] By adopting the above technical solution, the bottom end of the support screw tube is equipped with a stop seat through a rotatable connection. The height of the stop seat can be changed by adjusting the up and down position of the support screw tube, thereby meeting the needs of surfaces of different heights.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The online sampling design, which integrates the detection interface of the guide cylinder and the gate for rapid control, enables simultaneous detection and pouring, completely eliminating process interruption issues. During detection, the slump detection cylinder is simply connected to the detection helical tube of the guide cylinder via a threaded ring. Pulling the gate allows the concrete flowing in the guide cylinder to directly enter the detection cylinder. After sampling, releasing the gate and the return spring pushes the gate to seal the detection helical tube. The entire detection process does not require stopping the unloading of the tanker or the conveying of the guide cylinder, and the pouring operation can be carried out continuously. This completely avoids the cold joints in the concrete caused by the interruption of traditional detection, eliminates the need for additional roughening and grouting, shortens the construction period of a single project, and improves construction efficiency by eliminating interruptions. 2. Traditional testing requires sampling at a fixed frequency and cannot respond to changes in concrete condition in real time; this technology can pull the gate to sample at any time according to the concrete flow state, and the number of samplings per day can be flexibly adjusted, so as to detect abnormal slump in time, avoid unqualified concrete pouring due to delayed detection, and reduce rework costs. The sampling point is synchronized with the pouring flow, eliminating spatial deviations and improving detection accuracy. Addressing the shortcomings of traditional testing methods where spatial differences between sampling points and pouring points, as well as variations in concrete condition, lead to detection errors, this technology ensures that the test sample is completely consistent with the actual poured concrete condition through a design that directly samples from the main flow channel of the feed cylinder. The sample originates from the main flow channel, ensuring no difference in condition. The testing helical tube is directly installed on the side wall of the feed cylinder. During sampling, concrete directly enters the testing cylinder from the main flow channel within the feed cylinder. Traditional sampling involves taking samples from the unloading port of the tanker truck or the end of the chute. During concrete transportation, changes in slump are easily caused by moisture evaporation and aggregate settlement. This technology reduces the distance between the sampling point and the pouring point, minimizes the time difference between sampling and pouring, and ensures that the test results reflect the actual slump of the concrete at the pouring point, thus reducing the deviation rate.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application discloses a mobile concrete conveying device. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A mobile concrete conveying device includes a support component 1, a conveying cylinder 2, and a detection component 3. The support component 1 includes a support frame 11, two brackets 13 are symmetrically and vertically fixed on the top surface of the support frame 11, and the conveying cylinder 2 is connected and assembled at the top of the two brackets 13 of the support frame 11. A receiving hopper 22 is vertically connected and fixed at the upper part of the outer circumference of the conveying cylinder 2, and a detection screw tube 23 is vertically connected and fixed at the bottom of the outer circumference of the conveying cylinder 2. The detection component 3 is assembled and connected at the bottom end of the detection screw tube 23. One side of the outer circumference of the detection screw tube 23 is open, and a gate 231 is slidably inserted into the opening of the detection screw tube 23. The detection component 3 includes a slump detection cylinder 31, a screw ring 32 is vertically connected and fixed at the top end of the slump detection cylinder 31, and the screw ring 32 is threadedly connected to the detection screw tube 23. The bottom end of the slump detection cylinder 31 is open, and a base plate 33 is detachably assembled at the bottom end of the slump detection cylinder 31.

[0025] By adopting the above technical solution, the support frame 11 of the support component 1 provides stable support for the entire device, and the bracket 13 is used to securely install the guide cylinder 2. The guide cylinder 2 is mainly used for conveying concrete. The receiving hopper 22 at the top can effectively guide the concrete into the guide cylinder, while the detection screw tube 23 at the bottom is used to collect concrete samples. The gate 231 can close the detection screw tube 23 when needed to facilitate testing. The slump detection cylinder 31 in the detection component 3 is used to detect the slump of the concrete. The screw ring 32 allows it to be reliably connected to the detection screw tube 23, and the bottom plate 33 can be installed to close the slump detection cylinder 31 after testing. Concrete enters the guide cylinder 2 through the receiving hopper 22, then reaches the detection screw tube 23 and is partially stored. By rotating the screw ring 32 to connect the slump test cylinder 31 and the test screw tube 23, concrete samples are collected into the slump test cylinder 31. Then, the test hole is exposed by moving the gate 231, and the staff can observe or take samples for slump testing. After the test, the bottom plate 33 is replaced to seal the slump test cylinder 31.

[0026] Reference Figure 4 A pull rod 232 is horizontally fixed to the outer wall of the gate 231, and a return spring 233 is horizontally fixed to the end of the pull rod 232. The other end of the return spring 233 is fixed to the outer circumference of the detection solenoid 23. The gate 231 controls the flow of fluid. The pull rod 232 connects the gate 231 and the return spring 233, ensuring that the gate can return to its original position in time when an abnormality is detected. The return spring 233 is connected to the pull rod 232 and fixed to the outer circumference of the detection solenoid 23. When the gate 231 deviates from its normal position during flow detection, the return spring 233 provides a restoring force, causing the gate 231 to quickly return to its initial position, thereby ensuring the normal operation of the system. During this process, the detection solenoid 23 is used to detect the fluid flow status. Once an abnormality is detected, the pull rod 232 and the return spring 233 will cause the gate 231 to close or adjust in time, achieving effective control and protection of the fluid flow.

[0027] Reference Figure 5 The lower outer wall of the slump testing cylinder 31 is vertically and rotatably connected with screws 35, and the outer surface of the base plate 33 is horizontally fixed with screw seats 34, with the screws 35 and screw seats 34 threadedly connected. The main function of the slump testing cylinder 31 is to provide a standard measurement space during concrete slump testing to ensure the accuracy and consistency of the test. The screws 35 are designed to lock the base plate 33 at the bottom end of the slump testing cylinder 31 to seal it.

[0028] Reference Figure 4Both sides of the outer circumference of the guide cylinder 2 are horizontally fixed with lugs 21, and locking bolts 211 are vertically threaded through the lugs 21. The lugs 21 have vertically threaded holes, allowing for precise adjustment and fixation of the guide cylinder 2 using the locking bolts 211. A vertically opening threaded groove 131 is provided on the top surface of the bracket 13, and this groove is threadedly connected to the locking bolts 211. The top surface of the bracket 13 has a threaded groove 131 for inserting the locking bolts 211. By adjusting the depth to which the locking bolts 211 are screwed into the threaded groove 131, precise fixation of the guide cylinder 2 can be achieved, ensuring its stability during operation.

[0029] Reference Figure 3 The support frame 11 has wheels 12 rotatably connected to both sides of its bottom surface, and swivel seats 14 are symmetrically and vertically fixed at both ends of its bottom surface. The support frame 11 is mainly used to bear and support the entire device. The wheels 12 are mounted on both sides of its bottom surface by a rotatable connection to ensure that the device can move horizontally easily. Swivel seats 14 are mounted at both ends of the bottom surface of the support frame 11 to fix the rotating rod 15. The rotating rod 15 is horizontally rotatably connected to the swivel seats 14 at both ends of the bottom surface of the support frame 11, and a screw 16 is vertically fixed in the middle of the rotating rod 15. The screw 16 is vertically fixed in the middle of the rotating rod 15, and the screw 16 is vertically threaded inside the support screw tube 17, so that the support screw tube 17 can move up and down. The support screw tube 17 is vertically threaded onto the screw 16, and a stop 18 is rotatably connected to the bottom end of the support screw tube 17. The bottom end of the support screw tube 17 is rotatably connected to a stop 18. The height of the stop 18 can be changed by adjusting the up and down position of the support screw tube 17, thereby adapting to the needs of surfaces of different heights.

[0030] The implementation principle of a mobile concrete conveying device according to an embodiment of this application is as follows: First, the support frame 11 is moved by the wheels 12. After the concrete is guided to the pouring site, the concrete in the tanker is poured into the receiving hopper 22 on the outer wall of the guide cylinder 2. The concrete flows into the guide cylinder 2 and flows to the concrete pouring site under the guidance of the guide cylinder 2. At the same time, in order to ensure the flowability of the concrete in the guide cylinder 2, the support screw tube 17 is rotated on the abutment 18. The screw 16 in the support screw tube 17 moves vertically upward, driving the rotating rod 15 to deflect on the rotating seat 14 on the bottom surface of the support frame 11. This adjusts the support frame 11 to tilt toward the pouring point. By adjusting the inclination of the guide cylinder 2, the concrete flow rate is accelerated. Then, when it is necessary to take samples to test the slump of the concrete, the top threaded ring 32 of the slump testing cylinder 31 in the testing component 3 is threadedly connected to the testing screw tube 23 on the outer wall of the guide cylinder 2. The bottom plate 33 is then set at the bottom of the slump testing cylinder 31, and the screw 35 on the outer wall of the slump testing cylinder 31 is threadedly connected to the screw seat 34 of the bottom plate 33. The gate plate 231 on the testing screw tube 23 is pulled and moved laterally on the testing screw tube 23, compressing the return spring 233 to deform, so that the concrete flows into the slump testing cylinder 31 through the testing screw tube 23. After the concrete in the slump testing cylinder 31 is full, the gate plate 231 is released. Under the deformation force of the return spring 233, the gate plate 231 is pushed into the testing screw tube 23, completing the sealing of the testing screw tube 23. Thus, according to the degree of concrete pouring, test samples can be collected at any time without stopping the pouring, shortening the concrete pouring time.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
