[0043] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0044] This invention provides an automated sample preparation and curing equipment for ready-mixed concrete, comprising:

[0045] Overall framework 21;

[0046] The following components are installed below the overall frame 21: conveyor track 2, detachable receiving trolley 1, vibration platform 13, mold support 22, sliding lifting device 8, multi-functional mold library, curing chamber 16, and demolding device 17.

[0047] An intelligent lifting material handling machine 3 is installed on a vertical support 211 on the side of the overall frame 21 near the conveyor track 2 and can move up, down, left and right.

[0048] And a top clamping device 12 that is set on the horizontal support 212 of the overall frame 21 and can move forward, backward and left and right.

[0049] The overall frame 21 is a support frame used to fix and install the intelligent lifting material handling machine 3 and the top clamping device 12.

[0050] The overall frame 21 includes a horizontal transverse support 212 and vertical supports 211 set at both ends of the transverse support 212. A track is set on the transverse support 212 along its length direction. A steel plate 11 is fixed on the track by a slider. The setting direction of the steel plate 11 is perpendicular to the setting direction of the transverse support 212, that is, the steel plate 11 is arranged in the front-back direction. The top clamping device 12 is fixed on the steel plate 11. The top clamping device 12 can move left and right by driving and transmission mechanism (not shown in the figure) to drive the steel plate 11 to slide along the track on the transverse support 212. A track is also set on the steel plate 11. The track is laid along the length direction of the steel plate 11 (i.e., the front-back direction). The top clamping device 12 is slidably set in the track by a slider. The top clamping device 12 can move in the front-back direction by driving and transmission mechanism (not shown in the figure) along the track on the steel plate 11. The top clamping device 12 moves in the left, right, front, and rear directions to move the empty mold, the mold containing the ready-mixed concrete sample, and the empty mold and concrete test block after demolding.

[0051] The intelligent lifting material reclaimer 3 is fixed on the vertical support 211. The intelligent lifting material reclaimer 3 is used to transport the receiving hopper 1-1 loaded with pre-mixed concrete. It can lift the receiving hopper 1-1 vertically and move it horizontally left and right. The intelligent lifting material reclaimer 3 includes a wire rope 31, a horizontal pushing device 32, and a clamping device 33. The clamping device 33 is fixed to the horizontal pushing device 32 by the wire rope 31. A vertical slide rail can be vertically installed on the vertical support 211. The horizontal pushing device 32 is movably mounted on the slide rail via a slider. A drive and transmission mechanism (not shown in the figure) can drive the horizontal pushing device 32 to move up and down, thereby enabling the clamping device 33 to move up and down. The horizontal pushing device 32 can also move the clamping device 33 left and right. This function can be achieved through various structural schemes. This application does not specify the details of the horizontal pushing device 32. The structure is defined as follows: for example, the horizontal pushing device 32 consists of a horizontal rod, a slide rail fixed to the bottom of the horizontal rod, a slider set on the slide rail, and a drive motor and transmission mechanism fixed on the horizontal rod. The wire rope 31 is fixed on the slider. When the drive motor moves the slider on the slide rail through the transmission mechanism, the slider can move left and right synchronously with the wire rope 31 and the clamping device 33 to move the clamping device 33 above the detachable receiving trolley 1, so as to clamp the receiving hopper 1-1 of the detachable receiving trolley 1. The clamping device 33 can be moved down or up by lowering or tightening the wire rope 31.

[0052] The gripping device 33 is a gripping robot, and its gripper has a circular through hole.

[0053] The detachable receiving trolley 1 is slidably mounted on the conveyor track 2 and can move along the conveyor track 2 to directly below the intelligent lifting material handling machine 3.

[0054] The detachable receiving trolley 1 is used for loading and transporting ready-mixed concrete. The detachable receiving trolley 1 has a detachable upper and lower structure, consisting of an upper receiving hopper 1-1 and a lower transport trolley 1-4. The receiving hopper 1-1 and the transport trolley 1-4 can be separated or integrated. When the receiving hopper 1-1 and the transport trolley 1-4 are integrated, the receiving hopper 1-1 is mounted on the transport trolley 1-4. A controller 1-3 is installed on the receiving hopper 1-1 to control its opening and closing. Hopper handles 1-2 are fixed to the front and rear ends of the receiving hopper 1-1, respectively. When the clamping device 33 clamps the receiving hopper 1-1, it first aligns the circular through hole on the clamping hand of the clamping device 33 with the hopper handle 1-2, and then controls the clamping hand of the clamping device 33 to close. In this way, the hopper handle 1-2 passes through the circular through hole on the clamping hand. Then the clamping device 33 can move upward and to the right to send the receiving hopper 1-1 loaded with premixed concrete to the top of the empty mold (the empty mold coated with release agent) located on the vibrating platform 13.

[0055] The conveyor track 2 is laid along the transverse support 212 of the overall frame 21 and its right end abuts against the root of the vibration platform 13.

[0056] The vibration platform 13 is used to vibrate the concrete when pouring concrete into the empty mold. The vibration platform 13 has a built-in vibrator. After the empty mold is coated with release agent, it is placed on the vibration platform by the top clamping device 12.

[0057] The mold support 22 is located on the right side of the vibration platform 13. One end of the fixed support 10 is slidably located on the right side of the right frame of the mold support 22, and the other end is fixed on the left side of the vibration platform 13. The fixed support 10 can move back and forth.

[0058] Specifically, front and rear slide rails 15 are provided on the left side of the vibration platform 13 and the right side of the right frame of the mold support 22. The left end of the fixed bracket 10 is set on the front and rear slide rails 15 of the vibration platform 13, and the right end is set on the front and rear slide rails 15 on the right side of the right frame of the mold support 22. The fixed bracket 10 can be moved back and forth along the front and rear slide rails 15 by using a drive motor and a transmission mechanism.

[0059] The fixed bracket 10 is equipped with a smoothing device 14 and an intelligent coating device 9. The smoothing device 14 is located above the vibration platform 13. When the fixed bracket 10 moves back and forth along the front and rear slide rails 15, the fixed bracket 10 can move back and forth synchronously with the smoothing device 14 and the intelligent coating device 9.

[0060] The smoothing device 14 is used to smooth the mold containing the concrete sample. The smoothing device 14 is located on the left side of the fixed bracket 10. The smoothing device 14 includes a third push cylinder 14-1 fixed on the fixed bracket 10 and a smoothing tool 14-2 fixed to the piston rod end of the third push cylinder 14-1. The extension of the piston rod of the third push cylinder 14-1 allows the smoothing tool 14-2 to move downwards until it contacts the upper surface of the mold. Then, the fixed bracket 10 moves the entire smoothing device 14 back and forth to achieve the smoothing process. After the smoothing process is completed, the third push cylinder 14-1 and the smoothing tool 14-2 return to their original positions.

[0061] A rotating shaft is horizontally arranged on the fixed bracket 10, and the intelligent coating device 9 is installed on the rotating shaft. The rotating shaft is driven to rotate by a motor, and the motor can be fixed on the fixed bracket 10.

[0062] The intelligent coating device 9 includes a coating sleeve 9-1 fixed on a rotating shaft and rotating under the drive of the shaft. Multiple second push cylinders 9-2 are fixed circumferentially to the coating sleeve 9-1. Each second push cylinder 9-2 has a coating tool 9-3 fixed to the end of its piston rod. The types of coating tools 9-3 installed on different second push cylinders 9-2 are different. When the rotating shaft rotates, it drives the coating sleeve 9-1 to rotate, thereby adjusting the required type of coating tool 9-3 to be opposite the empty mold. Then, the piston rod of the second push cylinder 9-2 corresponding to the coating tool 9-3 is extended, causing the coating tool 9-3 to move downwards and apply release agent to the empty mold placed on the pad 7.

[0063] The pad 7 is moved from the right side to the left side of the mold support 22 by the sliding lifting device 8. The sliding lifting device 8 is located on the front and rear sides of the mold support 22.

[0064] The sliding lifting device 8 includes a base 8-1, a drive mechanism fixed on the base 8-1, a sliding lifting bracket 8-2 movably disposed within the base 8-1 and movable left and right under the drive mechanism, a lifting slide rail 8-3 vertically disposed on the sliding lifting bracket 8-2, and a lifting slider 8-4 locked on the lifting slide rail 8-3.

[0065] The front and rear ends of the pad 7 are respectively locked in the grooves of the lifting sliders 8-4 located on the front and rear sides of the mold support 22. In this way, by moving the front and rear two sliding lifting devices 8, the pad 7 carrying the empty mold can be moved from the right side to the left side of the mold support 22.

[0066] The mold support 22 is a U-shaped support. The left frame of the mold support 22 is adjacent to the vibration platform 13. The right side of the right frame of the mold support 22 is provided with a front and rear slide rail 15 that allows the fixed support 10 to move back and forth. The front and rear sides of the right frame of the mold support 22 are provided with an upper and lower slide rail 5 that allows the mold pushing device to move up and down. Multiple vertical frame through holes 22-1 are provided at equal intervals on the right frame of the mold support 22.

[0067] The mold pushing device is used to push the empty mold located at the left end of the multi-functional mold library horizontally out onto the pad 7 located on the left side of the multi-functional mold library. The sliding lifting device 8 then moves the pad 7 carrying the empty mold to the left and lifts it upward to be flush with the vibration platform 13 for sample preparation.

[0068] The mold pushing device includes a pushing slider 23 located on the right side of the right frame of the mold support 22 and with its end locked in the upper and lower sliding rails 5, and a plurality of first pushing cylinders 6 located on the pushing slider. The positions of the first pushing cylinders 6 correspond one-to-one with the positions of the frame through holes 22-1. The piston rod of the first pushing cylinder 6 passes through the pushing slider and can extend out of the frame through holes 22-1, thereby horizontally pushing the empty mold at the exit of the multi-functional mold magazine onto the pad plate 7.

[0069] The multifunctional mold storage room is used to store empty molds. It consists of multiple vertically arranged conveyor devices, each storing different types of molds. In this embodiment, the multifunctional mold storage room comprises three conveyor devices: a compression mold conveyor device 41, a flexural mold conveyor device 42, and a permeability-resistant mold conveyor device 43. The compression mold conveyor device 41 is located above the flexural mold conveyor device 42, and the flexural mold conveyor device 42 is located above the permeability-resistant mold conveyor device 43.

[0070] According to the sample of concrete test block to be prepared, control the mold pushing device to move up and down (use the drive motor and transmission mechanism to move the mold pushing device up and down), adjust the mold pushing device to the same height as the corresponding conveying device, and then control the first pushing cylinder 6 to act. The piston rod of the first pushing cylinder 6 extends out from the through hole 22-1 of the frame, thereby pushing the empty mold at the exit of the multi-functional mold library horizontally onto the pad 7.

[0071] The multifunctional mold library surrounds the mold support 22, the curing chamber 16, and the demolding device 17. The curing chamber 16 and the demolding device 17 are located on the right side of the mold support 22. Specifically, the right end of the multifunctional mold library is arranged around to the right side of the demolding device 17 so that its mold inlet is opposite to the demolding device 17, and the left end of the multifunctional mold library is arranged around to the left side of the right frame of the mold support 22 so that its mold outlet is opposite to the mold pushing device on the mold support 22.

[0072] The curing chamber 16 consists of three types of curing chambers: compression curing chamber 16-1, flexural curing chamber 16-2, and impermeability curing chamber 16-3. Each curing chamber is equipped with a temperature and humidity sensor inside, a temperature and humidity control box outside, and a timed door switch on the top of the chamber to ensure that the curing conditions of the concrete specimens in each type of curing chamber are precise and controllable.

[0073] The demolding device 17 is located on the right side of the curing chamber 16. The demolding device 17 includes a demolding platform for placing the molded concrete sample, a control box 20 located on one side of the demolding platform, a robotic arm 18 mounted on the control box 20 and capable of horizontal rotation and vertical lifting under the control of the control box 20, and an air pump 19 fixed to the end of the robotic arm 18 for demolding the molded concrete sample. The control box 20 controls the robotic arm 18 to rotate horizontally and lift vertically. After positioning it at the cavity containing the concrete sample mold, the air pump 19 demolds the molded concrete sample.

[0074] This invention also provides a method for using the above-mentioned automatic sample preparation and curing equipment for ready-mixed concrete, specifically including the following steps:

[0075] S1, after receiving the pre-mixed concrete, the detachable receiving trolley 1 moves to the right along the conveyor track 2. When the bottom right side of the detachable receiving trolley 1 contacts the platform (the platform at the bottom of the vibrating platform 13), the conveyor track 2 stops moving. When the detachable receiving trolley 1 stops moving, it is also located directly below the intelligent lifting material handling machine 3.

[0076] S2, the multi-functional mold library provides empty molds according to the type of concrete test block to be produced.

[0077] The empty mold at the exit of the multi-functional mold library is horizontally pushed onto the pad 7 using the mold pushing device (at this time, the pad 7 is located on the left side of the multi-functional mold library). Then, the pad 7 carrying the empty mold is moved to the left and lifted upwards by the sliding lifting device 8 until it is flush with the vibration platform 13 for sample preparation. Then, the intelligent coating device 9 controls the rotation of the shaft according to the style of the empty mold to adjust the coating tool 9-3 of the corresponding style to be opposite to the empty mold for applying the release agent.

[0078] S3, after the release agent is applied, the intelligent coating device 9 resets and exits the operation, and the empty mold is clamped on the table of the vibration platform 13 using the top clamping device 12.

[0079] S4, the intelligent lifting material handling machine 3 lower clamping device 33 is moved to the hopper handles 1-2 on both sides of the separable receiving trolley 1. After the clamping device 33 is fixed to the hopper handles 1-2, the clamping device 33 is lifted upward, and the receiving hopper 1-1 is separated from the transport trolley 1-4. The clamping device 33 is first lifted upward to the set height, and then moved to the right to clamp and transport the receiving hopper 1-1 to the top of the empty mold that has been coated with release agent. Then, the bottom of the receiving hopper 1-1 is opened to pour the premixed concrete into the empty mold. At the same time as the premixed concrete is poured, the vibrating platform 13 also vibrates. The receiving hopper 1-1 continues to pour until the empty mold is filled.

[0080] S5, after the empty mold is filled with ready-mixed concrete, the intelligent lifting material receiving machine 3 sends the receiving hopper 1-1 back to the transport trolley 1-4 of the detachable receiving trolley 1, while the smoothing device 14 smooths the ready-mixed concrete sample in the mold.

[0081] S6, the top clamping device 12 moves to the top of the mold containing the ready-mixed concrete sample, and the top clamping device 12 puts the mold containing the ready-mixed concrete sample into the curing chamber of the corresponding test block type for sample forming. After the sample forming is completed, the curing chamber door opens automatically, and the top clamping device 12 then puts the mold containing the ready-mixed concrete sample onto the demolding device 17 for demolding.

[0082] S7, the top clamping device 12 places the empty mold after demolding into the mold inlet of the corresponding conveying device of the multi-functional mold library, and the conveying device conveys the empty mold to the mold outlet to wait for the next sample making and repeated use.

[0083] The top clamping device 12 clamps the demolded concrete specimens and places them into the corresponding curing chambers for curing. The curing chambers are sealed structures and equipped with a temperature and humidity control system to simulate the concrete curing process under different environmental conditions. Each categorized curing chamber is equipped with an independent temperature and humidity sensor and control device to ensure that the curing conditions of the ready-mixed concrete specimens in each sample compartment are precise and controllable.

[0084] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
