[0014] The installation method for nuclear chemical cement curing line equipment provided by this invention includes: S1: Before pouring concrete to form the curing chamber, fixing the curing partition components to the steel reinforcement frame of the curing chamber, and then pouring concrete to form the curing chamber; S2: Installing a lifting device on the floor inside the curing chamber; S3: Installing first roller conveyors on both sides of the lifting device along the extension direction of the curing line, such that the end of the first roller conveyor furthest from the lifting device extends outside the curing chamber; S4: Installing a lifting door on the side of the end of the first roller conveyor furthest from the lifting device; S5: Installing photoelectric components at the reserved photoelectric holes in the wall of the curing line; S6: Hoisting and fixing the external mixing device into the curing chamber. This installation method for nuclear chemical cement curing line equipment is used in the installation process of nuclear chemical cement curing production line equipment. Nuclear chemical cement curing production line equipment typically needs to be installed in a factory building formed by civil construction. This factory building includes multiple rooms, and various devices on the production line equipment are correspondingly installed in multiple rooms. For example, one room is the curing chamber, and the curing partitions are installed in this curing chamber. The installation method for the nuclear chemical cement curing line equipment provided by this invention needs to be coordinated with the civil construction process. Specifically, during the civil construction process before installation, the curing partition components need to be fixed to the steel reinforcement frame of the curing chamber according to step S1, and then the curing chamber is formed by pouring concrete. The inner wall of the curing chamber can be fully covered by the embedded plate of the curing partition components. The embedded plate is used to fix and connect with devices such as the external mixing device and the photoelectric tube protective door inside the curing chamber to support and fix the device. In addition, during the civil construction process, photoelectric holes need to be reserved in the wall of the curing line according to the installation requirements of the photoelectric components, based on step S5. After the curing chamber and other rooms are poured, a lifting device is installed on the floor of the curing chamber according to step S2. The lifting device is used to drive the barrel placed on it to rise so as to receive liquid materials such as cement mortar. After the lifting device is installed, the first roller conveyor is installed on both sides of the lifting device along the extension direction of the curing line according to step S3. The first roller conveyor can be fixed to the embedded plate of the curing partition component in the curing chamber. Extending both ends of the first roller conveyor to the outside of the curing chamber facilitates the connection between the first roller conveyor and other roller conveyors outside the curing chamber. After the first roller conveyor is constructed, a lifting door is installed on the side of the first roller conveyor away from the lifting device according to step S4. The lifting door is located outside the curing chamber. Specifically, lifting doors are installed in the adjacent rooms on both sides of the curing chamber. The lifting doors are used to raise or lower according to the production line conditions to connect or isolate the first roller conveyor from other roller conveyors. After completing step S4, proceed to step S5 to install the photoelectric component at the reserved photoelectric hole on the wall of the curing line, and then proceed to step S6 to hoist and fix the external mixing device into the curing chamber. The external mixing device can enter the curing chamber through the reserved hole at the top of the curing chamber, and the external mixing device can be fixedly connected to the embedded plate in the curing chamber to realize its installation and fixing process.It can be seen that steps S1-S6 in the installation method of the nuclear chemical cement curing line equipment provided by the present invention guide the installation process and sequence of the roller conveyor, curing partition component, lifting device, lifting door, photoelectric component, and external mixing device, making the installation process of various devices in the production line more orderly and reasonable, effectively preventing the installation sequence of some devices from being chaotic and affecting the installation process of other devices, thereby improving installation efficiency and installation accuracy.

[0015] Compared with the prior art, the installation method for nuclear chemical cement curing line equipment provided by the present invention provides clear guidance on the installation process of roller conveyors, curing partition components, lifting devices, lifting doors, cap removal devices, photoelectric components, external mixing devices, and other devices in the cement curing production line equipment through steps S1-S6, making the construction process more orderly and thus improving installation efficiency and accuracy.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Example: like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment includes: Step S1: Before pouring the concrete to form curing chamber 1, fix the curing partition components to the steel reinforcement frame of curing chamber 1, and then pour the concrete to form curing chamber 1. Step S2: Install the lifting device 10 on the floor inside the curing chamber 1; Step S3: Install the first roller conveyor 2 on both sides of the lifting device 10 along the extension direction of the curing line, and make the end of the first roller conveyor 2 away from the lifting device 10 extend out of the curing chamber 1. Step S4: Install the lifting door 3 on the side of the first roller conveyor 2 away from the end of the lifting device 10; Step S5: Install photoelectric components 4 at the reserved photoelectric holes in the wall along the curing line; Step S6: Hoist and fix the external mixing device 11 into the curing chamber 1.

[0023] This installation method for nuclear chemical cement curing line equipment is used in the installation process of nuclear chemical cement curing production line equipment, such as... Figure 2 , Figure 3 and Figure 4 As shown, nuclear chemical cement curing production line equipment typically needs to be installed in a factory building constructed during civil engineering. This factory building includes multiple rooms, and various devices on the production line equipment are correspondingly installed in these rooms. For example, ... Figure 3 and Figure 5 As shown, one of the rooms is curing chamber 1, and the curing partition is installed in curing chamber 1.

[0024] The installation method for the nuclear chemical cement curing line equipment provided in this embodiment needs to be coordinated with the civil construction process. Specifically, during the civil construction process before installation, the curing partition components need to be fixed to the steel frame of the curing chamber 1 according to step S1, and then the curing chamber 1 is formed by pouring concrete. The inner wall of the curing chamber 1 can be fully covered by the embedded plate of the curing partition components. The embedded plate can be made of steel and is used to fix and connect with the external mixing device 11, photoelectric tube protective door, and other devices inside the curing chamber 1 to support and fix the devices. In addition, during the civil construction process, photoelectric holes need to be reserved in the wall of the curing line according to the installation requirements of the photoelectric components 4 based on step S5.

[0025] like Figure 3 As shown, after the curing chamber 1 and the remaining rooms are poured, a lifting device 10 is installed on the ground inside the curing chamber 1 according to step S2. The lifting device 10 is used to drive the barrel placed on it to rise so as to receive the cement mortar and other media in the equipment inside the curing chamber 1. After the lifting device 10 is installed, the first roller conveyor 2 is installed on both sides of the lifting device 10 along the extension direction of the curing line according to step S3. The first roller conveyor 2 can be fixed to the pre-embedded plate in the curing chamber 1. By extending both ends of the first roller conveyor 2 outside the curing chamber 1, it is easy to connect the first roller conveyor 2 with other roller conveyors outside the curing chamber 1. After the construction of the first roller conveyor 2 is completed, a lifting door 3 is installed on the side of the first roller conveyor 2 away from the lifting device 10 according to step S4. The lifting door 3 is located outside the curing chamber 1. Specifically, lifting doors 3 are installed in the adjacent rooms on both sides of the curing chamber 1. The lifting doors 3 are used to rise or fall according to the production conditions of the production line to connect or isolate the first roller conveyor 2 and other roller conveyors. After completing step S4, proceed to step S5 to install the photoelectric component 4 at the reserved photoelectric hole on the wall of the curing line, and then proceed to step S6 to hoist and fix the external mixing device 11 into the curing chamber 1. The external mixing device 11 can enter the curing chamber 1 through the reserved hole at the top of the curing chamber 1, and the external mixing device 11 can be fixedly connected to the embedded plate in the curing chamber 1 to realize its installation and fixing process.

[0026] It can be seen that steps S1-S6 in the installation method of the nuclear chemical cement curing line equipment provided in this embodiment guide the installation process and sequence of the roller conveyor, curing partition component, lifting device 10, lifting door 3, photoelectric component 4, and external mixing device 11, making the installation process of various devices in the production line more orderly and reasonable, effectively preventing the installation sequence of some devices from being chaotic and affecting the installation process of other devices, thereby improving installation efficiency and installation accuracy.

[0027] Compared with the prior art, the installation method for nuclear chemical cement curing line equipment provided in this embodiment provides clear guidance on the installation process of devices such as roller conveyors, curing partition components, lifting devices 10, lifting doors 3, cap removal devices 5, photoelectric components 4, and external mixing devices 11 in the cement curing production line equipment through steps S1-S6, making the construction process more orderly and thus improving installation efficiency and accuracy.

[0028] It should be noted that the installation accuracy and position of the lifting device 10 in step S2 are strictly required. Therefore, the symmetry of the lifting device 10 at its center and perpendicular to the curing line must be 1mm, and the symmetry of the lifting device 10 at its center and parallel to the curing line must also be 1mm. Furthermore, a tray can be installed on the top of the lifting device 10, and the deviation between the upper surface of the tray and the horizontal plane should not exceed 0.2mm. After the lifting device 10 is installed, it needs to be adjusted to ensure that its lifting movement is smooth, easy, noiseless, and accurately positioned. After adjustment, the lifting device 10 needs to undergo no-load and load tests. The no-load test involves 20 unloaded lifting and lowering cycles, and the load test involves placing a 1000kg weight on the lifting device 10 and then starting the lifting device 10 to lift and lower 5 times. The lifting device 10 is considered qualified if it can meet the above number of cycles.

[0029] During the installation of the first roller conveyor 2 in step S3, the base plate of the first roller conveyor 2 must first be spot-welded to the embedded plate, ensuring that the centerline distance between the base plates of the two sides of the first roller conveyor 2 meets the design requirements. Next, the elevation of the upper surface of the base plate of each first roller conveyor 2 is measured to calculate the flatness of all the base plates. Then, the elevation of the base plates is adjusted by adding or removing shims or changing the shim thickness to ensure that all base plates are on the same plane, and the flatness deviation of the base plates is no greater than 0.2mm. The first roller conveyor 2 is then positioned on the base plate, ensuring that the driving direction of the motor used to drive the rotation of the first roller conveyor 2 is correct. The motor bracket used to support the motor can be fixed to the embedded plate inside the curing chamber 1.

[0030] The installation parameters of the first roller conveyor 2 should meet the following requirements: the levelness of the transport plane of the first roller conveyor 2 in both directions perpendicular to and parallel to the curing line should not exceed 1 / 1000; the overall levelness of the first roller conveyor 2 should not exceed 5mm; the height difference at the junction of two adjacent roller conveyors should not exceed 0.3mm; and the symmetry of the first roller conveyor 2 on the horizontal axis passing through its center and perpendicular to the curing line should be ±1mm. If the above parameters are not met, they should be adjusted using shims until they meet the requirements. After all parameters have passed acceptance, the base plate of the first roller conveyor 2 should be fully welded to the embedded plate.

[0031] In addition, the first roller conveyor 2 must also meet the following installation requirements: each bearing and gear meshing part of the first roller conveyor 2 must be filled with lubricant such as molybdenum disulfide grease; the rotating parts of the first roller conveyor 2 must be able to rotate flexibly and smoothly, and the noise during the rotation process must not exceed 85 decibels; after the first roller conveyor 2 is installed, it must be subjected to no-load test and load test. The no-load test means running the first roller conveyor 2 in both forward and reverse directions for 10 minutes each. If the first roller conveyor 2 can operate normally, it is qualified; the load test means filling the barrel (400L steel barrel) with a heavy object (weighing 900Kg) and placing it on the first roller conveyor 2, and then running the first roller conveyor 2 in both forward and reverse directions for 6 minutes each. If the first roller conveyor 2 can operate normally, it is qualified.

[0032] The installation position of the optoelectronic component 4 in step S5 is as follows: Figure 2 and Figure 3 As shown, when installing the photoelectric component 4, the required elevation line and axis line for the installation of the photoelectric component 4 can be laid out in the room where the photoelectric component 4 needs to be installed, and the size of the reserved photoelectric hole in the room can be checked to ensure that the space required for the placement of the photoelectric component 4 is met. Then, the photoelectric component 4 is placed in the room. At this time, lifting lugs can be welded on both sides of the photoelectric component 4 body according to the actual site conditions to facilitate its hoisting and placement. After hoisting and placement, the position of the photoelectric component 4 is adjusted to meet its installation requirements. Then, the position of the photoelectric component 4 is reinforced (for example, by using steel profiles and steel plates as supports) to ensure that it will not shift during the concrete pouring process. After the photoelectric component 4 is effectively fixed, the lifting slings are removed, and the photoelectric component 4 is protected as necessary (to ensure that the photoelectric component 4 will not be contaminated during the grouting process). Then, it is handed over to the civil construction unit to grout the reserved photoelectric hole to fix the photoelectric component 4.

[0033] It should be noted that, as Figure 3 As shown, a photoelectric device 40 can be installed near the end of the curing line. The photoelectric device 40 is used to detect whether the barrel has reached the end of the curing line. Therefore, the photoelectric device 40 does not need to be fixed in the room, but can be fixed to one side of the curing line by a bracket.

[0034] In step S1, the curing partition components can be lifted using a 650t truck crane. It should be noted that the model and specifications of the lifting equipment used to lift the curing partition components need to be calculated and selected based on the progress of civil construction. Specifically, taking a curing partition component weighing 24,000 kg and a lifting hook and sling totaling 500 kg as an example, the lifting load is Q = Q1 + Q2 = 24,500 kg, where Q1 is the weight of the curing partition component and Q2 is the total weight of the lifting hook and sling. Based on the lifting load, a 650t truck crane is selected, with a load rate of 24,500 ÷ 29,500 = 83%, which meets the lifting safety requirements.

[0035] In step S1, during the hoisting of the curing partition component, to further ensure hoisting safety, a trial hoisting can be performed with the hook empty first. After the trial hoisting, the curing partition component on the hoisting hook of the truck crane is slowly moved towards the curing chamber 1. During this process, care must be taken to ensure that the curing partition component does not collide with other objects. Then, the curing partition component is slowly lowered to the installation position inside the curing chamber 1.

[0036] After the external mixing device 11 is hoisted into place in step S6, the fixing and installation process of the external mixing device 11 can be carried out. At this time, it can be checked whether the installation direction and position number of the external mixing device 11 in the curing chamber 1 meet the requirements of the drawing. If they do, the position of the external mixing device 11 is adjusted so that the center of the external mixing device 11 coincides with the horizontal axis parallel to the curing line in the curing chamber 1, and the perpendicularity between the vertical surface and the horizontal surface on the outer wall of the external mixing device 11 is no greater than 1 mm, the parallelism between the vertical surface on the outer wall of the external mixing device 11 and the extension direction of the first roller conveyor 2 is no greater than 1.5 mm, and the horizontality of the horizontal surface on the outer wall of the external mixing device 11 is no greater than 1.2 mm. In addition, the bottom of the external mixing device 11 is usually equipped with a discharge hood. When adjusting the position of the external mixing device 11, it is also necessary to ensure that the parallelism between the plane where the bottom pipe opening of the discharge hood is located and the horizontal plane is no greater than 0.5 mm. After adjusting the position of the external mixing device 11, external rods such as steel sections are used to fix the external mixing device 11 at the top opening of the curing chamber 1 and protect the external mixing device 11. Then, the civil engineering construction unit is handed over to the external mixing device 11 for secondary grouting to seal the opening.

[0037] It should be noted that the devices to be installed in the curing chamber 1 include not only the external mixing device 11, but also other devices to be installed in the curing chamber 1, such as the phototube protective door, during the process of hoisting the external mixing device 11 into the curing chamber 1. The phototube protective door is used to protect the phototubes to be installed in the curing chamber 1. After installation, it should ensure that the rotating parts are flexible and easy to use, and can stay in any rotating position.

[0038] The external mixing device 11 may include a mixing tank, a transmission mechanism, a cylinder system, a transmission rod, a ball joint, a corrugated pipe protective cover, a through-wall sleeve, a discharge cylinder, and other components. During the installation of the external mixing device 11, the mixing tank can be hoisted into place first, and then the transmission mechanism can be connected and fixed to the mixing tank with fasteners. Then, the cylinder system, transmission rod, ball joint, corrugated pipe protective cover, and through-wall sleeve can be assembled with the mixing tank as a whole. Next, the discharge cylinder bracket can be spot-welded to the embedded plate in the curing chamber 1, and the position of the discharge cylinder bracket can be adjusted using shims and shims to ensure that the discharge cylinder moves smoothly without jamming. Finally, the discharge cylinder can be fixed on the discharge cylinder bracket by using positioning pins.

[0039] The assembly process of the external mixing device 11 must meet the following technical requirements: the movement of all transmission and lubrication components in the external mixing device 11 must be smooth and free from jamming or stiffness; the piston opening and closing process at the bottom port of the discharge hood should be easy, flexible, and free from jamming, and the piston's sealing performance must be guaranteed; the verticality of the mixing shaft inside the mixing tank should be 0.5mm, the radial runout of the mixing shaft should not exceed 0.15mm, and the axial runout should not exceed 0.5mm; the piston at the bottom port of the discharge hood can be opened not only by the discharge cylinder but also manually, and the verticality deviation of the centerline of the port should not exceed 1mm.

[0040] After the external mixing device 11 is assembled, it needs to be tested. Specifically, the external mixing device 11 should be run for 10 minutes each at 10 r / min, 150 r / min, and 196 r / min, without any abnormal noise or vibration. Add 380 L of clean water to the mixing tank and mix for 10 minutes at each of the above speeds, without any abnormal noise or vibration. Add 380 L of clean water to the mixing tank and mix for 30 minutes at each of the above speeds. The pressure in the sealed cavity of the external mixing device 11 should be 0.1 MPa, the flow leakage should not exceed 50 ml / h, and the temperature should not exceed 80℃.

[0041] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes a step after step S3: Step S30: Install the cap removal device 5 in the room near the end of the curing line of the curing chamber 1; Step S31: Install and connect the second roller conveyor 20 on the side of the first roller conveyor 2 away from the curing chamber 1 near the end of the curing line, and position the second roller conveyor 20 below the cap removal device 5. Based on this, in step S4, a first lifting door is installed on the side of the first roller conveyor 2 near the starting point of the curing line, away from the end of the lifting device 10, and a second lifting door is installed on the side of the second roller conveyor 20 away from the end of the lifting device 10.

[0042] In this embodiment, the curing line includes a transport line for moving the barrel from one end to the other, the transport line being composed of... Figure 4 The roller conveyor system is shown. On this conveyor line, empty drums are transported from one end to below the external mixing device 11 to hold cement materials and other media falling from the external mixing device 11. The drums can then continue to move to exit from the other end of the conveyor line. The starting point of the curing line is the feeding end of the conveyor line, which is the end where the empty drum enters the conveyor line, and the ending point of the curing line is the discharging end of the conveyor line, which is the end where the drum containing the media exits the conveyor line.

[0043] like Figure 3 As shown, the cap-removing device 5 can be installed in a room adjacent to the curing chamber 1 and located between the curing chamber 1 and the end of the curing line. The cap-removing device 5 is used to pick up the barrel cap and cover the barrel to close the top opening of the barrel when the first roller conveyor 2 transports the barrel on the lifting device 10 to its lower position.

[0044] The installation of the cap-removing device 5 must be strictly carried out according to the drawing to ensure precise alignment with the positioning devices such as the locator on the barrel. After assembly, the cap-removing device 5 must ensure accurate automatic cap-finding and cap-sealing functions, as well as smooth operation and no air leakage after sealing. The cap-removing device 5 can be installed using a tightening machine and can be operated fully automatically or manually.

[0045] In addition, such as Figure 3 As shown, the end of the first roller conveyor 2 away from the curing chamber 1 and the second roller conveyor 20 in step S31 are both located in the same room as the capping device 5. The second roller conveyor 20 is used to transport the barrel on the first roller conveyor 2 to the bottom of the capping device 5.

[0046] Based on the configuration of the second roller conveyor 20, the lifting gate 3 in step S4 can include a first lifting gate and a second lifting gate, and as follows: Figure 3 As shown, the first lifting door is installed on the side of the first roller conveyor 2 near the starting point of the curing line, away from the end of the lifting device 10, and the second lifting door is installed on the side of the second roller conveyor 20 away from the end of the lifting device 10.

[0047] The parameter requirements and installation requirements of the second roller conveyor 20 are the same as those of the first roller conveyor 2, and will not be repeated here.

[0048] For the first and second lifting doors, doorways must be pre-reserved in the room at the locations where they will be installed during the civil construction process. Then, during installation, bolts are first assembled onto the door frames, ensuring they are securely spot-welded. The door panels and frames are then assembled as a single unit. The door panels and frames are then hoisted to their installation positions and adjusted to meet requirements. This ensures the bottom of the door frame is flush with the zero-meter elevation, the vertical deviation of the door frame side is no more than 1mm, the door panel is perpendicular to the horizontal plane, and the asymmetry between the door panel's centerline and the second roller conveyor axis is ±2mm. The door frames are then securely fixed using steel components. The installation is then handed over to the civil construction unit for secondary grouting in the gap between the doorway and the door frame to secure the frame and seal the gap. After installation, both the first and second lifting doors should move smoothly and flexibly up and down without any jamming or stiffness.

[0049] Furthermore, such as Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes a step after step S4: Step S40: Install third roller conveyors 21 on the side of the first lifting door away from the lifting device 10 and on the side of the second lifting door away from the lifting device 10, respectively, so that the first roller conveyor 2 and the third roller conveyor 21 located on both sides of the first lifting door are connected, and the second roller conveyor 20 and the third roller conveyor 21 located on both sides of the second lifting door are connected.

[0050] like Figure 3 As shown, the third roller conveyor 21 near the first lifting gate is used to lay a roller conveyor between the first lifting gate and the starting point of the curing line so that the empty bucket at the starting point of the curing line can be transported to the first lifting gate. Correspondingly, the third roller conveyor 21 near the second lifting gate is used to lay a roller conveyor between the second lifting gate and the end point of the curing line so that the bucket containing cement material can continue to move towards the end point of the curing line after passing through the second lifting gate.

[0051] The parameter requirements and installation requirements of the third roller conveyor 21 are the same as those of the first roller conveyor 2, and will not be repeated here.

[0052] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment further includes a step after step S40: Step S41: Install a rotating roller conveyor 22 on the side of the third roller conveyor 21 away from the lifting device 10 on the side of the second lifting gate; Step S42: Install the fifth roller conveyor 23 on the side of the rotating roller conveyor 22 away from the third roller conveyor 21.

[0053] Please refer to the installation positions of the rotating roller conveyor 22 and the fifth roller conveyor 23. Figure 3 After the sealing device 5 seals the barrel lid onto the opening of the barrel, the outer wall of the barrel usually needs to be rinsed. Therefore, nuclear chemical cement curing lines typically also include a cleaning device. Based on this, this embodiment preferably also includes step S41, in which the rotating roller conveyor 22 rotates to drive the barrel on it to rotate, thereby allowing the barrel to be thoroughly rinsed and improving the cleanliness.

[0054] The fifth roller conveyor 23 in step S42 is used to connect with the rotating roller conveyor 22 so that the rinsed barrel can continue to move towards the end of the curing line.

[0055] The installation requirements for the rotating roller conveyor 22 can be the same as those for the first roller conveyor 2. However, unlike the first roller conveyor 2, after the rotating roller conveyor 22 is installed, the upper surface of its roller shaft needs to be 525mm away from the zero-meter elevation, and the flatness of the upper surface of the roller shaft is ±0.2mm.

[0056] The parameter requirements and installation requirements for the fifth roller conveyor 23 are the same as those for the first roller conveyor 2, and will not be repeated here.

[0057] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes a step after step S42: Step S43: Install sealed protective doors 6 on the side walls of the two rooms on both sides of the curing chamber 1, away from the curing chamber 1; Step S44: Install the sixth roller conveyor 24 on the side of the sealed protective door 6 away from the curing chamber 1, and connect the sixth roller conveyor 24 and the third roller conveyor 21, which are both close to the starting point of the curing line, to each other, and connect the sixth roller conveyor 24 and the fifth roller conveyor 23, which are both close to the ending point of the curing line.

[0058] The installation position of the sealed protective door 6 is as follows Figure 2 and Figure 3 As shown, the sealed protective door 6 is used to seal the rooms on both sides of the curing chamber 1.

[0059] When installing the sealed protective door 6, the components of the sealed protective door 6 can first be hoisted into the rooms on both sides of the curing chamber 1, and then installed inside the rooms. Specifically, the lower guide rail and bracket of the sealed protective door 6 are installed first inside the rooms, followed by the door panel and upper guide rail. The door panel should be perpendicular to the horizontal plane, and the distance between the center line of the door opening and the reference horizontal axis perpendicular to the curing line pre-laid out in the room should be 37mm ± 1.5mm. Then, the motor, connecting rod, and motor bracket are installed according to the door panel position. The motor is used to cooperate with the connecting rod to drive the sealed protective door 6 to slide along the guide rail. After the sealed protective door 6 is assembled, a trial run test is required. During the test, the door panel should move flexibly and smoothly without any stiffness or jamming. Furthermore, the door frame of the sealed protective door 6 must be sealed and welded to the pre-embedded plate (usually a steel plate) pre-embedded in the room.

[0060] like Figure 3 As shown, the sixth roller conveyor 24, which is close to the starting point of the curing line, is used to connect the starting point of the curing line and the third roller conveyor 21 so that the empty bucket at the starting point of the curing line can be transported to the third roller conveyor 21. Correspondingly, the sixth roller conveyor 24, which is close to the ending point of the curing line, is used to connect the fifth roller conveyor 23 and the ending point of the curing line so that the bucket containing cement material can be moved to the ending point of the curing line.

[0061] The parameter and installation requirements for the sixth roller conveyor 24 are the same as those for the first roller conveyor 2, and will not be repeated here.

[0062] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes the following steps after step S44: Step S45: Install the liquid receiving tray device in the curing chamber 1; Step S46: Install the inspection door 7 at the reserved inspection hole in the wall on the curing line, and install the protective transfer device 8 in the room between the second lifting door and the rotating roller conveyor 22; Based on this, in step S6, the external stirring device 11 is hoisted and fixed into the curing chamber 1, and the bottom of the external stirring device 11 is connected to the liquid receiving tray device.

[0063] The liquid receiving tray is usually ring-shaped and is used to connect with the bottom of the external mixing device 11. When the lifting device 10 drives the tank to rise, the liquid receiving tray can also connect with the top opening of the tank. It can be seen that the function of the liquid receiving tray is to prevent cement material from splashing outside the tank during the process of cement material falling from the external mixing device 11 into the tank.

[0064] During the installation of the drip tray device, the installation position line of the drip tray device can be laid out in the curing chamber 1 first, ensuring that the radial center axis of the drip tray device in the installation position line coincides with the reference horizontal axis parallel to the curing line pre-laid in the curing chamber 1, and that the elevation line of the drip tray device in the installation position line is 2175mm from the ground. Then, the penetrating component on the drip tray device is inserted into the hole reserved by the civil construction unit when pouring the curing chamber 1, and the parameters of the penetrating component are adjusted to meet its installation requirements. Then, the penetrating component is reinforced, and then handed over to the civil construction unit for secondary pouring in the gap between the penetrating component and the above-mentioned hole to fix the penetrating component and seal the gap. After the secondary pouring and curing period is completed, the penetrating component and the drip tray device are assembled.

[0065] After the drip tray device is installed, proceed to step S46. Please refer to the installation location of the inspection door 7. Figure 2 Please refer to the installation location of the protective transfer device 8. Figure 3 The inspection door 7 in step S46 is used for the entry and exit of inspection tools or personnel to facilitate daily maintenance and repair of the nuclear chemical cement curing line equipment. When installing the inspection door 7, the required elevation line and axis line for installation should first be laid out in the room where the inspection door 7 will be installed. The dimensions of the pre-reserved inspection holes made during the civil construction process should be checked to ensure they meet the space requirements for the door's placement. If they do, the inspection door 7 can be placed in the room. At this point, a lifting lug can be welded to each side of the inspection door 7 according to the actual site conditions to facilitate its hoisting. It should be noted that during hoisting, lifting points can be selected on the inspection door 7 according to the actual site conditions, and transfer tools such as gantry frames can be used. During the hoisting of the inspection door 7, it is also necessary to prevent the door leaf from rotating freely. Hoisting straps can be used to secure the inspection door 7. Next, the position of the inspection door 7 can be adjusted to meet the installation requirements. Then, the position of the inspection door 7 is reinforced (for example, by using structural steel and steel plates as supports inside the door) to ensure that it will not shift during the concrete pouring process. After the position of the inspection door 7 is fixed, the lifting slings are released, and the steel plate inside the inspection door 7 is welded and fixed to the inspection door 7. Then, it is handed over to the civil construction unit to grout the gap between the reserved inspection hole and the inspection door 7. After the grout layer has reached the curing period, the door leaf of the sealed door is manually pushed and pulled to ensure that the door leaf can stop at any angle without automatic opening and closing or jamming.

[0066] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes a step after step S5: Step S50: Install the dose rate detector bracket 9 near the end of the curing line; Step S51: Install the detection instrument tube assembly 90 in the room near the end of the curing line in the curing chamber 1; Step S52: Install the light fixture 91 at the reserved light fixture 91 hole in the wall along the curing line.

[0067] The dose rate detector bracket 9 supports the dose rate detector, which detects whether cement adheres to the outer wall of the barrel on one side. When installing the dose rate detector bracket 9, the installation axis of the bracket 9 can be laid out near the end of the curing line. Then, the bracket 9 is positioned and welded to a pre-embedded steel plate on the ground on one side of the curing line.

[0068] The installation position of the instrument tube assembly 90 is as follows: Figure 3 As shown, when installing the instrument tube assembly 90, the line can be laid out in the room near the end of the curing line in the curing chamber 1, so that the elevation line of the instrument tube assembly 90 is 1500mm from the ground. Then, the instrument tube assembly 90 is inserted into the reserved hole in the room, and its position is reinforced to prevent displacement during secondary pouring. Then, the hole is handed over to the civil construction scope for secondary pouring to fix the position of the instrument tube assembly 90.

[0069] The installation position of the lamp 91 in step S52 is as follows: Figure 3 As shown, when installing the light fixture 91, the required elevation line and axis line for the installation of the light fixture 91 can be laid out in the wall first, and the size of the reserved hole for the light fixture 91 can be checked to see if it meets the space requirements for the placement of the light fixture 91. Then, the embedded pipe used to fix the light fixture 91 is placed and its position in the reserved hole for the light fixture 91 is adjusted. Then, the position of the embedded pipe is reinforced to ensure that it will not be displaced during the concrete pouring process. After the necessary protection of the embedded pipe is completed (to ensure that the light fixture 91 will not be contaminated during the grouting process), it is handed over to the civil construction unit to grout the reserved hole for the light fixture 91. Then, the light fixture 91 is assembled at the embedded pipe.

[0070] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes a step after step S6: Step S60: Install cover plate 12 on top of curing chamber 1.

[0071] As mentioned earlier, the top of the curing chamber 1 is usually pre-drilled with an opening for hoisting and installing the external mixing device 11. After the installation of the external mixing device 11 is completed, a cover plate 12 needs to be installed at the opening to further ensure the airtightness of the curing chamber 1. Specifically, when installing the cover plate 12, the cover plate 12 can be hoisted to the installation position first, and the position of the cover plate 12 can be adjusted to meet the installation requirements. Then, external components such as steel sections are used to reinforce the position of the cover plate 12 to ensure that the cover plate 12 will not be displaced during grouting. Then, it is handed over to the civil construction unit for secondary pouring of the top opening of the curing chamber 1 to fix the position of the cover plate 12.

[0072] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes a step after step S60: Step S61: Install a cleaning device above and to the side of the curing line; Step S62: Install the unblocking device on the upper side of the curing line.

[0073] The cleaning device is used to rinse the outer wall of the barrel on the rotating roller conveyor 22. When installing the cleaning device, the high-pressure water unit and water tank of the cleaning device can be installed on the factory floor outside the room through the pre-embedded anchor bolts. Then, the high-pressure water unit and the high-pressure water actuator are connected through the high-pressure hose, and the high-pressure water actuator is inserted into the mixing tank through the top cover plate 12 of the curing chamber 1.

[0074] The unblocking device is used to unclog pipes in the nuclear chemical cement curing line equipment. When installing the device, it should be fixed above one side of the curing line, positioned outside the top cover plate 12 of the curing chamber 1. The furthest point reached by the unblocking head should ensure a minimum entry length of 10mm into the mixing tank. The actuator of the unblocking device penetrates the top cover plate 12 of the curing chamber 1 and enters the various connecting pipe ports of the mixing tank within the curing chamber 1.

[0075] like Figure 1 As shown, the installation method for the nuclear chemical cement curing line equipment provided in this embodiment also includes the following steps after step S62: Step S63: Install a viewing window at the reserved window opening on the wall along the curing line, and install a robotic arm at the reserved operation hole on the wall along the curing line.

[0076] The viewing window allows staff to monitor the operating status of each device on the nuclear chemical cement curing line in real time, while the robotic arm is used to perform various operations in rooms that are difficult for staff to access.

[0077] When installing a viewing window, the window frame is first hoisted to the pre-drilled window opening. Then, the civil engineering unit grouts the opening to secure the frame. After ensuring the room is dry and clean, and the viewing window surface is dry, clean, and free of scratches, an installation and maintenance vehicle is used for installation. Specifically, a crane is used to move the viewing window to the correct position, and bolts and pins are used to connect the connecting seat on the maintenance vehicle to the inner frame of the viewing window. The maintenance vehicle is then pushed to the front of the viewing window, and a steering mechanism is used to align the vehicle and the viewing window horizontally. The adjustment device on the maintenance vehicle is then adjusted so that the center of the connecting seat is at the same height as the center of the viewing window. The maintenance vehicle is then secured using the adjustment device, and bolts are used to connect the fixing plate at the front of the maintenance vehicle to the mating plate on the wall surrounding the window frame. A hand-cranked pushing mechanism is then used to push the viewing window into the window frame. The bolts and pins on the connecting seat are then removed, and the maintenance vehicle is moved to its final position using the hand-cranked pushing mechanism. Finally, the viewing window is fixed inside the window frame.

[0078] The robotic arm includes structures such as embedded wall pipes, sealing sleeves, sealing sleeve ejection tools, and jaw replacement devices. When installing the robotic arm, the embedded wall pipes can be installed first at the reserved operating holes in the room. The installation requirements for the embedded wall pipes are as follows: the maximum deviation of the horizontal center line distance between the embedded wall pipe and the corresponding viewing window is ±5mm; the maximum deviation of the installation height of the embedded wall pipe from the design height is ±5mm; the height deviation between the center axes of the two embedded wall pipes of each robotic arm is no more than 3mm; the allowable tolerance of the parallelism of the center axes of the two embedded wall pipes of each robotic arm is no more than 1 / 500; the horizontal inclination of the embedded wall pipe does not exceed 1.5mm over its entire length; and the flange at the operating end of the embedded wall pipe has multiple threaded holes, which must be symmetrically distributed along the vertical and horizontal directions. After the pre-embedded wall pipe is fixed at the reserved operating hole, the robot arm is lifted into the air using a lifting device. After powering on, the robot arm's forward and backward movement direction is adjusted to be horizontal. Then, the robot arm is lifted to the height of the pre-embedded wall pipe axis using a lifting device or maintenance vehicle. The robot arm is then pushed into the pre-embedded wall pipe until the rolling elements on the robot arm are flush with the flange of the pre-embedded wall pipe. Next, the hole position of the rolling elements is adjusted so that it corresponds and connects with the threaded hole position of the pre-embedded wall pipe. Finally, the robot arm and the pre-embedded wall pipe are tightened with bolts, thus completing the robot arm installation process.

[0079] After completing all the above steps, the installed equipment can be inspected regularly. The inspection includes the surrounding environment of the production line, signs and markings, orifice sealing, coverings, protective coatings and materials, cleanliness, and prevention of foreign objects. In addition, transparent plastic materials, dust and debris in the foreign object control area or adjacent area around the production line need to be cleaned and removed.

[0080] In summary, the installation method for nuclear chemical cement curing equipment provided in this embodiment forms a set of installation process technology for nuclear chemical cement curing production lines. It develops a construction technology for high-precision installation and assembly of modular equipment in the secondary pouring zone of the equipment room, overcomes the difficulties of assembling loose parts and conducting on-site commissioning in the secondary pouring zone, clarifies the construction logic of each component, and creates favorable conditions for subsequent processes.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
