[0003] Related technology can refer to the Chinese invention patent application with application number CN115582905A, which discloses a concrete curing equipment, a sealed curing box is provided with a gate door, a curing vehicle for placing initial setting concrete precast blocks is arranged in the curing box, the width of the curing vehicle is smaller than the width of the door body in the gate door, and a plurality of steam outlets are arranged on the bottom plate of the curing box, and each of the steam outlets is connected to the steam main pipe outside the curing box through a steam pipe.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: in order to ensure that the temperature and humidity of the concrete curing equipment remain stable, the concrete curing equipment is usually set as a closed body, resulting in that after the concrete parts are transported into the concrete curing equipment, their moving progress cannot be observed. Therefore, it may be impossible to move the concrete parts to the preset positions, and repeated adjustments to the positions of the concrete parts will affect the curing efficiency. Summary of the invention

[0005] In order to improve the problem that concrete parts cannot stop automatically after moving to a preset position, the present application provides a concrete curing device.

[0006] The concrete curing equipment provided in this application adopts the following technical solution:

[0007] A concrete curing device comprises a curing room and a slide rail penetrating the curing room; a curing vehicle is slidably arranged along the length direction of the slide rail, a lead screw is rotatably arranged on the slide rail along its own length direction, a threaded tube is rotatably arranged in the curing vehicle, a plug-in piece is slidably arranged in the curing vehicle along its own width direction, and a plug-in groove which can be plugged into the plug-in piece is provided on the outer circumference of the threaded tube; the lead screw is penetrating the threaded tube, and the lead screw is threadedly connected to the threaded tube; an electromagnet is embedded and fixed on the inner wall of the curing room, and a magnetic attraction piece which can be magnetically adsorbed by the electromagnet is fixed to one end of the plug-in piece close to the electromagnet.

[0008] By adopting the above technical solution, the maintenance vehicle can keep moving forward only when the connector and the threaded pipe remain in a plugged state; when the maintenance vehicle moves to the point where the electromagnet and the connector are aligned, the electromagnet attracts the magnetic sheet to separate the connector from the threaded pipe; the threaded pipe that has lost its limiting function cannot continue to drive the maintenance vehicle forward, so that the maintenance vehicle can automatically stop at a preset position in the maintenance room.

[0010] By adopting the above technical solution, the guide groove provides a guiding function for the guide plate, making it easy for the plug-in plate to move along the width direction of the maintenance vehicle.

[0011] Optionally, a spring 1 is fixed to a side of the guide plate away from the threaded tube, and an end of the spring 1 away from the threaded tube is fixedly connected to a side wall of the guide groove away from the threaded tube.

[0012] By adopting the above technical solution, spring 1 provides the connector with an elastic force away from the threaded tube, making it easy to drive the connector to separate from the threaded tube through spring 1; when the magnetic force provided by the electromagnet is not enough to offset the elastic force of spring 1, the threaded tube will stop rotating due to the separation of the connector and the threaded tube.

[0013] Optionally, a thermistor is fixed to the inner wall of the curing chamber, and the thermistor is connected in series with the electromagnet and the power supply to form a series circuit.

[0014] By adopting the above technical solution, after the electromagnet and the thermistor are connected in series, when the temperature in the maintenance room is too high, the resistance of the thermistor itself increases, resulting in a decrease in the current passing through the electromagnet and a decrease in the magnetic force of the electromagnet; after the magnetic force exerted by the electromagnet on the magnetic suction cup is reduced, the connector will automatically reset, thereby restoring the threaded transmission matching relationship between the threaded tube and the lead screw, and the maintenance vehicle will continue to move forward after the temperature reaches the preset temperature, indicating that the maintenance is completed.

[0016] By adopting the above technical solution, the slider and the screw thread transmission cooperate to drive the gate one to open; the bevel gear two can provide the bevel gear one with rotational power, so that the screw rotates and opens the gate one, making it convenient for the maintenance vehicle to leave the maintenance room.

[0017] Optionally, the rotating component includes a connecting shaft rotatably arranged in the slide groove three; a connecting groove which can be plugged into the end of the connecting shaft is opened on the side of the bevel gear two away from the bevel gear one; a slide groove four is opened on the side around the slide groove three, and a magnetic disk which can be slidably connected in the slide groove four along the length direction of the curing room and can be adsorbed by the electromagnet away from the end of the screw.

[0018] By adopting the above technical solution, the strength of the magnetism of the electromagnet will also affect the movement of the magnetic disk and the connecting shaft; when the magnetism of the electromagnet is strong, the connecting shaft is separated from the second bevel gear; when the magnetism of the electromagnet is weak, the connecting shaft is plugged into the second bevel gear, and the rotation of the connecting shaft drives the second bevel gear to rotate, thereby realizing the opening of the gate, so that the maintenance vehicle can leave the maintenance room after the temperature reaches the preset temperature.

[0019] Optionally, the magnetic disk is sleeved on the circumferential side of the connecting shaft; two chucks are fixed to the outer circumferential surface of the connecting shaft, and the magnetic disk is located between the two chucks.

[0024] By adopting the above technical solution, the guide hole provides a guiding function for the guide bar, so that the two can maintain relative sliding while the pulley 2 drives the connecting shaft to rotate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The maintenance vehicle can only keep moving forward when the plug-in piece and the threaded pipe remain plugged in; when the maintenance vehicle moves to the point where the electromagnet and the plug-in piece are aligned, the electromagnet attracts the magnetic sheet to separate the plug-in piece from the threaded pipe; the threaded pipe that loses its limiting function cannot continue to drive the maintenance vehicle forward, so that the maintenance vehicle automatically stops at the preset position in the maintenance room;

[0027] 2. After the electromagnet and the thermistor are connected in series, when the temperature in the maintenance room is too high, the resistance of the thermistor itself increases, resulting in a decrease in the current passing through the electromagnet and a decrease in the magnetic force of the electromagnet; after the magnetic force exerted by the electromagnet on the magnetic chuck decreases, the connector will automatically reset, thereby restoring the threaded transmission matching relationship between the threaded tube and the lead screw. The maintenance vehicle will continue to move forward after the temperature reaches the preset temperature, indicating that the maintenance is over;

[0028] 3. The strength of the magnetism of the electromagnet will also affect the movement of the magnetic disk and the connecting shaft; when the magnetism of the electromagnet is strong, the connecting shaft is separated from the second bevel gear; when the magnetism of the electromagnet is weak, the connecting shaft is plugged into the second bevel gear, and the rotation of the connecting shaft drives the second bevel gear to rotate, thereby opening the gate, so that the maintenance vehicle can leave the maintenance room after the temperature reaches the preset temperature.

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The present application embodiment discloses a concrete curing device. Figure 1 and Figure 2 , including a curing room 1 and a slide rail 11 that runs through the curing room 1. A curing vehicle 2 is slidably arranged along the length direction of the slide rail 11. A lead screw 12 is rotatably arranged on the slide rail 11 along its own length direction, and a motor 13 for providing power to the lead screw 12 is arranged at the end of the lead screw 12, and the output shaft of the motor 13 is fixedly connected to the end of the lead screw 12. A steam pipe 14 for conveying high-temperature steam to the curing room 1 is arranged at the bottom of the curing room 1, and a water pipe 15 is fixedly arranged at the top of the curing room 1, and a plurality of nozzles 16 are fixedly arranged on the water pipe 15 along its own length direction. A gate 1 3 is arranged at the outlet of the curing room 1 along the vertical sliding direction, and a gate 2 32 is hinged at the entrance of the curing room 1.

[0037] The steam pipe 14 is used to transport high-pressure steam into the curing room 1 to improve the high-temperature curing environment. When the temperature in the curing room 1 is too high, water is sprayed into the curing room 1 through the water pipe 15 to cool it down.

[0038] Reference Figure 3 and Figure 4 The base of the maintenance vehicle 2 is provided with a through hole 21 through which the lead screw 12 can pass. A mounting groove 31 is provided in the base of the maintenance vehicle 2 on the side of the through hole 21, and a threaded tube 22 is rotatably provided in the mounting groove 31; the lead screw 12 passes through the threaded tube 22, and the lead screw 12 is threadedly connected to the threaded tube 22. Two slide grooves 1 23 are symmetrically provided in the radial direction of the through hole 21 in the base of the maintenance vehicle 2, and a plug-in piece 24 is slidably connected in the slide groove 1 23 along the width direction of the maintenance vehicle 2, and a plug-in groove 25 is provided on the outer peripheral surface of the threaded tube 22 to be plugged with the plug-in piece 24.

[0039] The lead screw 12 drives the maintenance vehicle 2 forward by threading with the threaded tube 22. The threaded tube 22 can only be threaded with the lead screw 12 in a limited state, and the threaded tube 22 will be in a limited state only when the plug-in piece 24 is plugged with the threaded tube 22.

[0040] Reference Figure 3 and Figure 4 Guide pieces 26 are symmetrically fixed on both sides of the plug-in piece 24, and guide grooves 27 are respectively provided on the two opposite inner walls of the slide groove 23. The guide pieces 26 are slidably arranged in the guide grooves 27 along the width direction of the maintenance vehicle 2. A spring 28 is fixed on the side of the guide piece 26 away from the threaded tube 22, and the end of the spring 28 away from the threaded tube 22 is fixedly connected to the side wall of the guide groove 27 away from the threaded tube 22.

[0041] Reference Figure 2 The inner wall of the curing room 1 is embedded with an electromagnet 4, and a magnetic sheet 41 that can be magnetically adsorbed with the electromagnet 4 is fixed to one end of the plug-in sheet 24 close to the electromagnet 4. A thermistor 42 is fixed to the inner wall of the curing room 1, and the thermistor 42 is connected in series with the electromagnet 4 and the power supply to form a series circuit.

[0042] After the maintenance vehicle 2 moves to the position where the electromagnet 4 and the plug-in piece 24 are aligned, the electromagnet 4 can separate the plug-in piece 24 from the threaded tube 22 by adsorbing the magnetic sheet 41 , and the threaded tube 22 loses its limiting function and no longer drives the maintenance vehicle 2 forward.

[0043] The thermistor 42 is used to measure the temperature in the curing room 1. When the temperature in the curing room 1 is too high, the resistance of the thermistor 42 gradually increases under the influence of temperature, resulting in a decrease in the current in the series circuit, a decrease in the magnetism of the electromagnet 4, and the connector 24 and the threaded tube 22 resuming the plug-in relationship.

[0044] Reference Figure 2 The side wall at the outlet of the curing chamber 1 is provided with two vertically arranged chute 2 43; a screw 44 is rotatably arranged in the chute 2 43; a slider 45 is sleeved around the screw 44 and threadedly arranged, and the slider 45 is vertically slidably arranged in the chute 2 43. The gate 1 3 is vertically slidably arranged at the outlet of the curing chamber 1, and the side wall of the gate 1 3 is fixedly connected to the slider 45. A bevel gear 1 46 is fixed at the bottom end of the screw 44.

[0045] Reference Figure 2 , Figure 3 and Figure 5The side of the second slide groove 43 away from the lead screw 12 is provided with a third slide groove 47 arranged along the length direction of the curing chamber 1, and a connecting shaft 48 is rotatably arranged in the third slide groove 47. The side of the third slide groove 47 close to the bevel gear 1 46 is rotatably installed with a second bevel gear 49 that can mesh with the first bevel gear 46. The side of the second bevel gear 49 away from the bevel gear 1 46 is provided with a connecting groove 33 that can be plugged into the end of the connecting shaft 48; in this embodiment, the cross sections of the connecting shaft 48 and the connecting groove 33 are both square.

[0046] Reference Figure 5 A chute 4 34 is provided on the circumference of the chute 3 47, and the chute 4 34 is connected to the chute 2 43. A magnetic disk 35 is slidably connected in the chute 4 34 along the length direction of the curing chamber 1, and can be adsorbed by the end of the electromagnet 4 away from the lead screw 12. The magnetic disk 35 is sleeved on the circumference of the connecting shaft 48; two chucks 36 are fixed on the outer circumference of the connecting shaft 48, and the magnetic disk 35 is located between the two chucks 36.

[0047] The electromagnet 4 is used to provide magnetic attraction for the magnetic disk 35, and drives the connecting shaft 48 to move through the magnetic disk 35; after the connecting shaft 48 moves, the end of the connecting shaft 48 can be plugged into the connecting groove 33 on the bevel gear 2 49, thereby driving the screw 44 to rotate through the connecting shaft 48.

[0048] Reference Figure 1 and Figure 5 The end of the lead screw 12 near the motor 13 is sleeved with a pulley 1 5, and the inner wall of the entrance end of the curing chamber 1 is provided with a connecting groove 17. A pulley 2 51 is rotatably provided in the connecting groove 17. The pulley 2 51 is sleeved and slidably connected to the peripheral side of the connecting shaft 48. The pulley 1 5 and the pulley 2 51 are connected through a conveyor belt. A guide strip 52 is fixed to the outer peripheral surface of the connecting shaft 48, and a guide hole 53 is provided on the inner peripheral surface of the pulley 2 51. The guide strip 52 is slidably connected to the guide hole 53 along the length direction of the curing chamber 1.

[0049] The implementation principle of a concrete curing device in the embodiment of the present application is:

[0050] After the motor 13 is started, the lead screw 12 is driven to rotate, and the lead screw 12 drives the maintenance vehicle 2 forward by threading with the threaded tube 22. After the maintenance vehicle 2 moves to the position where the electromagnet 4 is aligned with the plug-in piece 24, the plug-in piece 24 is separated from the threaded tube 22, and the threaded tube 22 stops threading with the lead screw 12, so that the maintenance vehicle 2 stops moving. The second gate 32 is closed.

[0051] The steam pipe 14 delivers high-pressure steam to the curing room 1 to create a high-temperature curing environment. When the temperature in the curing room 1 is too high, water is sprayed into the curing room 1 through the water pipe 15 to cool it down.

[0052] When the temperature in the curing room 1 is higher than the preset temperature, the curing is finished; when the temperature in the curing room 1 gradually increases, the resistance of the thermistor 42 in the curing room 1 gradually increases, the current in the electromagnet 4 connected in series with the thermistor 42 decreases, and the magnetism of the electromagnet 4 decreases. After the electromagnet 4 cannot provide magnetic force for the magnetic attraction sheet 41, the plug-in sheet 24 is reconnected with the threaded tube 22, and the threaded tube 22 is threadedly matched with the lead screw 12 and drives the curing vehicle 2 to move toward the exit of the curing room 1.

[0053] At the same time, the electromagnet 4 cannot provide adsorption for the magnetic disk 35. The magnetic disk 35 drives the connecting shaft 48 to move toward the side close to the bevel gear 1 46. The bevel gear 2 49 contacts the bevel gear 1 46 and enters into a meshing state. The screw 44 is driven to rotate through the connecting shaft 48, and the gate 1 3 rises to open the exit of the curing room 1.

[0054] After the exit of the curing room 1 is opened, the temperature inside the curing room 1 decreases due to the temperature exchange between the inside and the outside, the magnetism of the electromagnet 4 is enhanced, the screw 44 stops rotating after the magnetic disk 35 moves, so that the gate 1 3 rises to a preset height and then stops rising.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
