Description

Technical Field

[0001] The present invention relates to the technical field of concrete fecal leakage plate production, and particularly to a continuous curing method for concrete fecal leakage plates. Background Art

[0002] In many modern large-scale pig farms, in order to keep the pigsty clean and facilitate the automatic cleaning of pig manure, concrete fecal leakage plates are generally used to build pigsties. The fecal leakage plates are produced using molds. In the prior art, there is already a relatively mature plate production line for mass production of fecal leakage plates. Among the related equipment of the plate production line, for example, the Chinese invention patent with the publication number CN109927164A discloses a production device for concrete fecal leakage plates, and the Chinese utility model patent with the publication number CN216737362U discloses a stacking vehicle for fecal leakage plates.

[0003] The process of producing concrete fecal leakage plates is basically as follows: Vibrate the concrete filled in the fecal leakage plate mold, then smooth the upper part, and then move the whole mold laterally for turnover demolding. After demolding, the fecal leakage plate to be cured is transported to the fecal leakage plate and pallet placement area together with the pallet by a transporter; finally, the fecal leakage plate together with the pallet is sent to be cured in stacks by a forklift, and after curing is completed, the cured fecal leakage plate is removed from the pallet.

[0004] In the curing link, on the one hand, the existing operation method has limited working space and insufficient steam curing chambers, and the time required for one steam curing is relatively long. The steam curing efficiency is much lower than the production efficiency of fecal leakage plates. After the fecal leakage plates to be cured are produced on the plate production line, they need to wait for the steam curing chamber to be vacated, and continuous batch production and curing cannot be achieved; on the other hand, using a forklift to transport the fecal leakage plates to be cured has high requirements for the energy, ability, etc. of the forklift driver. The transfer efficiency, safety, etc. are easily affected by it, and the degree of dependence on labor is relatively high, which is not conducive to mechanized production.

[0005] The Chinese invention patent with the publication number CN113602974A discloses a crane and an application method applied to a three-dimensional steam curing system for track slabs. By setting up a three-dimensional steam curing area and arranging a main beam platform assembly above the three-dimensional steam curing area that can move horizontally along the three-dimensional steam curing area, the main beam platform assembly is hoisted with a swing arm, and the swing arm clamps and lifts the track slab assembly, enabling the track slab assembly to be sent into the three-dimensional steam curing area for curing. It solves the problem of limited steam curing site, but there are still the following deficiencies: 1. In this technical solution, the main beam platform assembly and the three-dimensional steam curing area are integrated, and it is necessary to grab the track slab assembly to be cured directly below the three-dimensional steam curing area, which has great limitations on the usage scenarios and high costs, and lacks universality; 2. When grabbing the track slab assembly to be cured by the swing arm, it is necessary to reserve working space for the opening of the swing arm, which is not conducive to multi-station work; 3. When sending the track slab assembly, it is also necessary to rely on the traction parts inside the three-dimensional steam curing area to traction and move the track slab assembly, and it cannot complete the transfer work independently from the three-dimensional steam curing area, and has high requirements for the planning and design of the three-dimensional steam curing area. Summary of the Invention

[0006] The purpose of the present invention is to provide a continuous curing method for concrete fecal leakage plates to solve the problems encountered in the continuous curing after the production and manufacture of concrete fecal leakage plates.

[0007] To solve the above problems, the present invention adopts the following technical solutions:

[0008] A continuous curing method for concrete fecal leakage plates, in which a multi-layer curing device is arranged on one side of the tail of the plate-making production line, and a large vehicle track is arranged on the same side of the plate-making production line and the multi-layer curing device;

[0009] Taking the layout direction of the plate-making production line as the left-right direction, the multi-layer curing device includes multiple rows of steam curing houses arranged in the left-right direction. Each row of steam curing houses is provided with multiple steam curing chambers arranged in the up-down direction. The side of the steam curing chamber facing the large vehicle track can be opened and closed, and the large vehicle track is arranged in the left-right direction;

[0010] A continuous curing transfer vehicle travels on the large vehicle track. Taking the side of the temporary placement area of the fecal leakage plate on the plate-making production line as the initial position of the continuous curing transfer vehicle, after the continuous curing transfer vehicle moves along the large vehicle track to the initial position, it loads the fecal leakage plate produced by the plate-making production line together with the pallet onto the continuous curing transfer vehicle. The continuous curing transfer vehicle walks along the large vehicle track to the door of the corresponding steam curing house, and adjusts the positions of the transported fecal leakage plate and the pallet in the height direction to correspond to the steam curing chambers at different heights. Open the corresponding steam curing chamber, and the continuous curing transfer vehicle pushes the transported fecal leakage plate and the pallet into the corresponding steam curing chamber and then closes the steam curing chamber;

[0011] The continuous curing transfer vehicle returns to the initial position along the large vehicle track to wait for loading the next batch of fecal leakage plates and pallets, which completes one transfer of fecal leakage plates. During the continuous production process of the plate-making production line, the continuous curing transfer vehicle repeats the transfer work of fecal leakage plates multiple times to achieve the continuous production and curing of fecal leakage plates.

[0012] Optionally, a liftable lifting platform is provided inside the continuous curing transfer vehicle, and the fecal leakage plate is supported by the lifting platform. When the fecal leakage plate produced by the plate-making production line is shipped to the continuous curing transfer vehicle together with the pallet, the height at which the lifting platform is located is the initial height of the lifting platform. The process of the continuous curing transfer vehicle pushing the transported fecal leakage plates and pallets into the corresponding steam curing chamber includes the following steps:

[0013] Step S1, adjust the pushing height: After the continuous curing transfer vehicle travels to the front of a row of steam curing chamber doors, the lifting platform rises or falls in the height direction until it stops in front of the selected steam curing chamber;

[0014] Step S2, open the selected steam curing chamber;

[0015] Step S3, send the plate: The lifting platform supports the fecal leakage plate and the pallet through the plate-sending supporting wheels, controls the rotation of the plate-sending supporting wheels, and the fecal leakage plate pallet moves towards the selected steam curing chamber under the frictional action of the plate-sending supporting wheels;

[0016] Step S4, push the plate: When the fecal leakage plate and the pallet are separated from the plate-sending supporting wheels, a part of the fecal leakage plate and the pallet is still in the position where it has not entered the selected steam curing chamber. The lifting platform completely pushes the fecal leakage plate and the pallet into the selected steam curing chamber through the claws of the plate-pushing mechanism. After that, the claws of the plate-pushing mechanism withdraw from the selected steam curing chamber;

[0017] Step S5, close the selected steam curing chamber;

[0018] Step S6, reset the lifting platform to the initial height.

[0019] Optionally, in step S4, the claws of the plate-pushing mechanism have at least two switchable positions in its circumferential direction. One position is the working position. In the working position, the highest point of the claw is higher than the highest point of the wheel surface of the plate-sending supporting wheel, so as to push the fecal leakage plate and the pallet when pushing the plate or pull out the fecal leakage plate and the pallet after curing; the other position is the avoidance position. In the avoidance position, the highest point of the claw is lower than the highest point of the wheel surface of the plate-sending supporting wheel. When the plate-pushing mechanism is in the non-working state, the claw switches to the avoidance position, is in a separated state from the fecal leakage plate pallet and will not hinder the movement of the fecal leakage plate pallet.

[0020] Optionally, each steam curing room is equipped with a sliding side door that can slide up and down, and each row of steam curing rooms is fixed with a side door guide rod. The distance between the top of the side door guide rod and the top of the row of steam curing rooms is greater than or equal to the height of a sliding side door. The opening and closing states of each steam curing room are independent of each other. When the steam curing room at the bottom is opened, its sliding side door slides upward and pushes the sliding side doors of the remaining steam curing rooms in the row upward, so that the remaining steam curing rooms in the row remain in a closed state.

[0021] Optionally, in order to achieve continuous action of adjusting the pushing height and opening the selected steam curing chamber, a door lifting mechanism capable of opening or closing the corresponding steam curing chamber is provided on the lifting platform.

[0022] Optionally, a support rod assembly that can move up and down is installed on the door lifting mechanism, and a door lifting support rod that can be extended or retracted is provided in the support rod assembly. A bracket groove is provided on the side of the sliding side door away from the interior of the steam curing chamber, and the bracket groove corresponds to the door lifting support rod.

[0023] Optionally, transport wheels for transporting the slatted boards and pallets to the continuous maintenance transfer vehicle are set up in the space between the temporary placement area of ​​the slatted boards of the board production line and the trolley track.

[0024] By adopting the above technical solution, the present invention has the following advantages:

[0025] The present invention arranges a multi-layer curing device and a continuous curing transfer vehicle for a matching board production line. On the one hand, the multi-layer curing device effectively utilizes the production site and can obtain more steam curing rooms. The slatted floor to be cured does not need to wait for a long time for the steam curing room to be vacated. On the other hand, the continuous curing transfer vehicle replaces the existing forklift transfer method and can realize overall movement, adjustment of pushing height, pushing of slatted floor, opening and closing of steam curing rooms, etc., which is conducive to realizing mechanized production and effectively improving work efficiency and work quality.

[0026] In the process of realizing continuous curing by the curing method of the present invention, the transfer vehicle and the steam curing room are independent of each other. The transfer vehicle integrates functions such as receiving, lifting, aligning, pushing the slatted floor and the pallet into the steam curing room, pulling them out of the curing room, and independently opening and closing the door of the steam curing room. There is no need to set up additional driving equipment in the steam curing room for control. Multiple tasks can be completed by means of the transfer vehicle, so as to achieve continuous connection between board production and placement of the boards after curing.

[0027] At the same time, on the one hand, the present invention can correspond to different rows of steam curing rooms by the transfer vehicle moving horizontally along the trolley track. On the other hand, the design can be adjusted according to site conditions to determine how many groups of slatted floor pallets and pallets can be transported at the same time. The lateral space of the lifting platform is widened without obstruction, and the work stations can be flexibly adjusted according to site conditions, so as to reasonably utilize the factory space and achieve optimal allocation of resources.

[0028] In the application of the present invention, after the door lifting mechanism determines the height position along with the lifting platform, it can control the opening and closing of the steam curing chambers at different height positions. Each steam curing chamber corresponds to a sliding side door that can slide up and down. When the door lifting mechanism makes the sliding side door slide upward, it will push up the sliding side doors of the other steam curing chambers above this steam curing chamber in the same column, so that the other steam curing chambers in this column remain closed. The opening and closing of each steam curing chamber do not occupy the space in the front, back, left, or right, and their opening and closing states are independent of each other. Whenever a fecal leakage plate and a supporting plate are fed in or taken out, the corresponding steam curing chamber door can be opened and closed immediately without affecting other steam curing chambers.

[0029] In summary, by adopting the continuous curing method of the concrete fecal leakage plate of the present invention, during the continuous production process of the plate-making production line, the continuous curing transfer vehicle can repeatedly perform the transfer work of the fecal leakage plates between the plate-making production line and the multi-layer curing device, realizing the continuous production and curing of the fecal leakage plates.

[0065] In order to make the technical purpose, technical solution and beneficial effects of the present invention clearer, the following Figure 1-19 The technical solution of the present invention is further illustrated with specific embodiments.

[0066] An embodiment of a continuous curing method for a concrete slatted floor:

[0067] A multi-layer curing device D is arranged on one side of the tail of the board production line A, and a trolley track C is arranged on the same side of the board production line A and the multi-layer curing device D. A board discharge area B is arranged on one side of the trolley track C. After curing, the slatted floor can be placed in the board discharge area B;

[0068] Taking the layout direction of the board - making production line A as the left - right direction, the multi - layer curing device D includes multiple rows of steam curing chambers arranged in the left - right direction. Each row of steam curing chambers is provided with multiple steam curing rooms 11 arranged in the up - down direction. One side of the steam curing room 11 facing the big vehicle track C can be opened and closed, and the big vehicle track C is arranged in the left - right direction;

[0069] There is a continuous curing transfer vehicle E running on the big vehicle track C. Taking the side of the temporary placement area of the fecal - leakage board of the board - making production line A as the initial position of the continuous curing transfer vehicle E, after the continuous curing transfer vehicle E moves along the big vehicle track C to the initial position, it loads the fecal - leakage board made by the board - making production line A together with the pallet onto the continuous curing transfer vehicle E. The continuous curing transfer vehicle E walks along the big vehicle track C to the door of the corresponding steam curing chamber, and adjusts the positions of the transported fecal - leakage board and pallet in the height direction to correspond to the steam curing rooms 11 at different heights. Then it opens the corresponding steam curing room 11, and after the continuous curing transfer vehicle E pushes the transported fecal - leakage board and pallet into the corresponding steam curing room 11, it closes the steam curing room 11;

[0070] The continuous curing transfer vehicle E returns along the big vehicle track C to the initial position to wait for loading the next batch of fecal - leakage boards and pallets, which means completing one transfer of the fecal - leakage board. During the continuous production process of the board - making production line A, the continuous curing transfer vehicle E repeats the transfer work of the fecal - leakage board multiple times to realize the continuous production and curing of the fecal - leakage board.

[0071] In specific implementation, in order to make more effective use of the space in the steam curing room 11, multiple fecal - leakage boards are generally stacked in stacks on the fecal - leakage board pallet (the fecal - leakage board pallet can be simply recorded as the pallet), and the pallet is generally of a frame structure. Each fecal - leakage board is separated by a partition. Each steam curing room 11 can correspond to different stacks of fecal - leakage boards according to the actual situation, and the continuous curing transfer vehicle E also transports them in stacks. According to the layout structure of the continuous curing transfer vehicle E, forms such as transporting one stack separately each time or transporting two stacks simultaneously each time can be selected. After curing, the fecal - leakage board is taken off the pallet. During the curing process, pushing the pallet means pushing the fecal - leakage board.

[0072] Furthermore, as one of the embodiments of the present invention, a lift platform 4 that can be lifted is arranged in the continuous curing transfer vehicle E, and the fecal - leakage board and the pallet are supported by the lift platform 4. Taking the height at which the lift platform 4 is located when loading the fecal - leakage board made by the board - making production line A together with the pallet onto the continuous curing transfer vehicle E as the initial height of the lift platform 4, the process of the continuous curing transfer vehicle E pushing the transported fecal - leakage board and pallet into the corresponding steam curing room 11 includes the following steps:

[0073] Step S1, adjust the pushing height: After the continuous curing transfer vehicle E travels to the front of a row of steam curing chamber doors, the lifting platform 4 rises or falls in the height direction until it stops in front of the selected steam curing chamber 11. When selecting the steam curing chamber 11, it is selected in the order of from bottom to top;

[0074] Step S2, open the selected steam curing chamber 11;

[0075] Step S3, send the plate: The lifting platform 4 supports the fecal leakage plate and the supporting plate through the plate feeding supporting wheels 63, controls the rotation of the plate feeding supporting wheels 63, and the fecal leakage plate supporting plate moves towards the selected steam curing chamber 11 under the friction of the plate feeding supporting wheels 63;

[0076] Step S4, push the plate: When the fecal leakage plate and the supporting plate are separated from the plate feeding supporting wheels 63, a part of the fecal leakage plate and the supporting plate is still in the position where it has not entered the selected steam curing chamber 11. The lifting platform 4 completely pushes the fecal leakage plate and the supporting plate into the selected steam curing chamber 11 through the claw 74 of the plate pushing mechanism 7. After that, the claw 74 of the plate pushing mechanism 7 withdraws from the selected steam curing chamber 11;

[0077] Step S5, close the selected steam curing chamber 11;

[0078] Step S6, the lifting platform 4 resets to the initial height.

[0079] Further, as one embodiment of the present invention, in step S4, the claw 74 of the plate pushing mechanism 7 has at least two switchable positions in its circumferential direction. One position is the working position. In the working position, the highest point of the claw 74 is higher than the highest point of the wheel surface of the plate feeding supporting wheels 63, so as to push the fecal leakage plate and the supporting plate or pull out the fecal leakage plate and the supporting plate after curing when pushing the plate; the other position is the avoidance position. In the avoidance position, the highest point of the claw 74 is lower than the highest point of the wheel surface of the plate feeding supporting wheels 63. When the plate pushing mechanism 7 is in a non-working state, the claw 74 switches to the avoidance position, is in a separated state from the fecal leakage plate supporting plate and will not hinder the movement of the fecal leakage plate supporting plate.

[0080] Further, as one embodiment of the present invention, each steam curing chamber 11 is equipped with a sliding side door 16 that can slide up and down. Each row of steam curing chambers is fixed with a side door guiding rod 17. The distance between the top of the side door guiding rod 17 and the top of this row of steam curing chambers is greater than or equal to the height of a sliding side door 16. The opening and closing states of each steam curing chamber 11 are independent of each other. When the lowermost steam curing chamber 11 is opened, its sliding side door 16 slides upward and pushes the sliding side doors 16 of the remaining steam curing chambers in this row upward, so that the remaining steam curing chambers in this row are still in a closed state.

[0081] Further, as one of the embodiments of the present invention, in order to make the actions of adjusting the pushing height and opening the selected steam curing chamber 11 continuous, a lifting door mechanism 8 capable of opening or closing the corresponding steam curing chamber 11 is provided on the lifting platform 4.

[0082] Further, as one of the embodiments of the present invention, a support rod assembly capable of moving up and down is installed on the lifting door mechanism 8. An elevating door support rod 84 capable of extending or retracting is provided in the support rod assembly. A support groove 161 is formed on the side of the sliding side door 16 away from the inside of the steam curing chamber 11, and the support groove 161 corresponds to the elevating door support rod 84.

[0083] Further, as one of the embodiments of the present invention, a conveying support wheel for loading the fecal leakage plate and the support plate onto the continuous curing transfer vehicle E is installed in the space between the temporary placement area of the fecal leakage plate of the formwork production line A and the large vehicle track C.

[0084] When applying the curing method of the present invention, after curing is completed, the same continuous curing transfer vehicle is used to pull out the cured fecal leakage plate and the support plate from the corresponding steam curing chamber. The process is as follows: after adjusting the pushing height and opening the door, the fecal leakage plate and the support plate are pulled out of the steam curing chamber 11 through the pushing plate mechanism 7, then retreated to directly below the top plate through the plate feeding mechanism 6, and then the lifting door mechanism 8 is used for closing the door operation. After resetting the lifting platform 4, the fecal leakage plate machine support plate can be retreated into the plate discharging area B for placement.

[0085] Whenever the fecal leakage plate and the support plate are fed in or taken out, the steam curing chamber door can be opened and closed immediately, ensuring that each steam curing chamber 11 is independent and does not affect each other during the curing process.

[0086] In the specific application of the continuous curing method of the concrete fecal leakage plate of the present invention, it can be implemented relying on the following fecal leakage plate continuous curing system.

[0087] The fecal leakage plate continuous curing system includes a multi-layer curing device D and a continuous curing transfer vehicle E;

[0088] As Figures 7 to 10 shown, the multi-layer curing device D includes at least one row of steam curing rooms. In the height direction of each row of steam curing rooms, a plurality of mutually independent steam curing chambers 11 are provided. Each row of steam curing rooms includes four support columns 12 surrounding a cuboid structure. On the front and rear end faces of the cuboid, a plurality of connecting braces 13 are uniformly arranged longitudinally. At least two parallel support beams 14 are fixed in each steam curing chamber 11. Taking the direction in which the continuous curing transfer vehicle E feeds the fecal leakage plate relative to the steam curing chamber 11 as the front-rear direction, a plurality of support rollers 15 are arranged on each support beam 14 in the front-rear direction;

[0089] Each steam curing chamber 11 is respectively equipped with a sliding side door 16 capable of sliding up and down;

[0090] As shown Figure 1 in FIG. 1, a multi-layer curing device D is arranged on one side of a large vehicle track C. Taking the extending direction of the large vehicle track C as the left-right direction, the continuous curing transfer vehicle E travels along the large vehicle track C. An outboard area B is arranged on one side of the large vehicle track C, and the fecal leakage plate can be placed in the outboard area B after curing is completed;

[0091] As shown Figures 2 to 6 in FIG. 2, the continuous curing transfer vehicle E includes a gantry upright 21 and running ground beams 23 installed on both sides of the bottom of the gantry upright 21. Two cross braces 24 in an X shape are fixed between the two running ground beams 23 on both sides, which can play a role in preventing deviation to a certain extent. The running ground beams 23 travel on the large vehicle track C installed on the ground through running wheels 25. In this embodiment, two gantry uprights 21 are arranged side by side to achieve structural stability. A large vehicle positioning assembly 26 is installed on the running ground beam 23. The large vehicle positioning assembly 26 includes a large vehicle positioning frame 261 and a large vehicle positioning hydraulic cylinder 262. The large vehicle positioning hydraulic cylinder 262 is vertically installed on the large vehicle positioning frame 261. The telescopic rod of the large vehicle positioning hydraulic cylinder 262 is hinged with a large vehicle positioning insertion rod 263. A positioning chute 264 is fixed on the large vehicle positioning frame 261. The large vehicle positioning insertion rod 263 is slidably connected with the positioning chute 264. An embedded iron 265 is fixed on the ground on one side of the large vehicle track C. A large vehicle positioning groove is opened at the top of the embedded iron 265. The bottom end of the large vehicle positioning insertion rod 263 matches the large vehicle positioning groove.

[0092] After the continuous curing transfer vehicle E loads the fecal leakage plate produced by the plate production line A, it travels along the large vehicle track C to the position corresponding to the steam curing chamber. When the continuous curing transfer vehicle E travels to the in-place position, the continuous curing transfer vehicle E can be positioned through the large vehicle positioning assembly 26.

[0093] A lifting mechanism 3 is installed on the top of the gantry upright 21. The lifting mechanism 3 is connected with a lifting platform 4 through a steel wire rope 31 and drives the lifting platform 4 to move up and down in the space below the gantry upright 21. In this embodiment, the lifting platform 4 is correspondingly installed with a platform guide wheel frame 43 for the gantry upright 21. A platform guide wheel 44 is rotatably connected in the platform guide wheel frame 43. A vertical slide rail is arranged on the gantry upright 21. The platform guide wheel 44 travels on the vertical slide rail;

[0094] There are at least two sets of plate feeding mechanisms 6 provided on the lifting platform 4. The lifting platform 4 supports the fecal leakage plates and the supporting plates through the plate feeding supporting wheels 63. Every two sets of plate feeding mechanisms 6 correspond to one steam curing chamber 11. A pushing plate mechanism 7 is correspondingly arranged between every two sets of plate feeding mechanisms 6. The pushing plate mechanism 7 can be fixed to or separated from the tail of the fecal leakage plate supporting plate. When the pushing plate mechanism 7 is fixed to the tail of the fecal leakage plate supporting plate, it can push the fecal leakage plate supporting plate to completely send the fecal leakage plates and the supporting plates into the steam curing chamber 11 or pull the fecal leakage plates and the supporting plates out of the steam curing chamber 11 after curing onto the plate feeding mechanism 6. When the plate feeding mechanism 6 is working, the pushing plate mechanism 7 is separated from the tail of the fecal leakage plate supporting plate.

[0095] Furthermore, as Figure 7 and Figure 10 shown, side door guiding rods 17 are fixed to each row of steam curing chambers. The sliding side door 16 is slidably connected to the side door guiding rods 17. The distance between the top of the side door guiding rod 17 and the top of this row of steam curing chambers is greater than or equal to the height of one sliding side door 16. The opening and closing states of each steam curing chamber 11 are independent of each other. When the lowermost steam curing chamber 11 is opened, its sliding side door 16 slides upward and pushes the sliding side doors 16 of the other steam curing chambers 11 in this row upward, so that the other steam curing chambers 11 in this row remain in the closed state.

[0096] Furthermore, as Figures 14 to 16 shown, a door lifting mechanism 8 capable of opening or closing the door is further provided on the lifting platform 4. The door lifting mechanism 8 includes two oppositely arranged door lifting columns fixed to the lifting platform 4. A connecting cross bar 813 is fixed between the door lifting columns. A rod supporting assembly capable of moving up and down along the door lifting columns is correspondingly installed on each door lifting column. The rod supporting assembly includes a door lifting moving seat 82, a door lifting hydraulic cylinder 83, and a door lifting rod 84. The door lifting hydraulic cylinder 83 is installed on the door lifting moving seat 82. The door lifting rod 84 extends in the front-back horizontal direction and extends or retracts under the action of the door lifting hydraulic cylinder 83. A supporting groove 161 is opened on the side of the sliding side door 16 away from the inside of the steam curing chamber 11. The supporting groove 161 corresponds to the door lifting rod 84.

[0097] When it is necessary to drive the sliding side door 16 of the steam curing chamber 11 to open or close through the door lifting mechanism 8, first move the rod supporting assembly to the height where the supporting groove 161 is located, and then control the door lifting rod 84 to extend and insert into the supporting groove 161 through the door lifting hydraulic cylinder 83. After that, while the rod supporting assembly moves up and down along the door lifting columns, the sliding side door 16 can be driven to move up and down, so as to realize the opening or closing of the steam curing chamber 11.

[0098] Further, the support rod assembly moves up and down along the lifting door column through a support rod lifting mechanism. The support rod lifting mechanism includes a rotating long shaft 85 and two sets of chain drive assemblies. The rotating long shaft 85 is rotatably connected to two lifting door columns at the same time. The rotating long shaft 85 is drivingly connected to a fourth reduction motor 87. The rotating long shaft 85 rotates under the drive of the fourth reduction motor 87. The fourth reduction motor 87 includes a reduction gearbox 86. The low-speed stage gear shaft hole in the reduction gearbox 86 is drivingly connected to the rotating long shaft 85. In this embodiment, the low-speed stage gear in the reduction gearbox 86 is arranged coaxially with the rotating long shaft 85. Each lifting door column corresponds to a set of chain drive assemblies. Each set of chain drive assemblies includes an upper sprocket 88, a lower sprocket 89 and a driving chain. The upper sprocket 88 and the lower sprocket 89 are respectively rotatably connected to the lifting door column. The upper sprocket 88 is drivingly connected to the rotating long shaft 85. The driving chain is connected between the upper sprocket 88 and the lower sprocket 89. The lifting door moving seat 82 is fixed at a position of the driving chain. In actual installation, the head and tail of the driving chain are connected at the lifting door moving seat 82 to form a closed loop, that is, one end of the driving chain is connected to the upper part of the lifting door moving seat 82, and the other end of the driving chain is connected to the lower part of the lifting door moving seat 82.

[0099] The rotating long shaft 85 rotates under the drive of the fourth reduction motor 87, thereby causing the upper sprocket 88 to rotate. The entire chain drive assembly can then make corresponding movements, ultimately driving the up and down movement of the lifting door moving seat 82.

[0100] Further, the lifting door column includes an inner column 811 and an outer column 812. Both the inner column 811 and the outer column 812 are provided with vertically arranged guiding long grooves. At least two lifting door guide wheels 821 are installed on the lifting door moving seat 82. The two lifting door guide wheels 821 respectively travel in the guiding long grooves of the inner column 811 and the outer column 812. The setting of the lifting door guide wheels 821 can prevent the support rod from deviating from the direction during the process of dragging the sliding side door 16 of the steam curing chamber 11 to move. In this embodiment, four lifting door guide wheels 821 are provided and are divided into two pairs arranged side by side up and down.

[0101] Further, as Figure 12 and Figure 13As shown, the push plate mechanism 7 includes a sliding support frame 71, a push slide bar 72, a push long shaft 73, a pull claw 74 and a push plate driving mechanism for moving the push slide bar 72 toward or away from the steam curing chamber 11. The push plate driving mechanism includes a second reduction motor 75, a push plate gear 76 and a push plate rack 77. The second reduction motor 75 is installed on the lifting platform 4 through a second motor bracket 78. The output shaft of the second reduction motor 75 is transmission-connected with the push plate gear 76. The push plate rack 77 is fixed to the bottom of the push slide bar 72 and is parallel to the axis of the push slide bar 72. The push plate rack 77 is meshed with the push plate gear 76. The sliding support frame 71 is fixed to the lifting platform 4, and the highest point of the sliding support frame 71 is lower than the highest point of the wheel surface of the plate sending wheel 63. The pushing slide bar 72 extends in the front and rear horizontal directions and is slidably connected to the sliding support frame 71. Specifically, the sliding support frame 71 includes a square slide and a leg. The leg is fixed to the lifting platform 4, the square slide is fixed on the leg, and the pushing slide bar 72 is a square structure matching the square slide bar and is slidably connected in the square slide bar. The pushing slide bar 72 is set to a square structure, which can prevent the pushing slide bar 72 from twisting in the circumferential direction, further improving the stability of the plate pushing process. The long shaft 73 is rotatably connected to the push slide rod 72, and the two ends of the push long shaft 73 extend out of the push slide rod 72, and the pulling claw 74 is fixed to the end of the push long shaft 73 close to the steam curing chamber 11. In this embodiment, the pulling claw 74 includes a vertical plate and a sleeve, the sleeve is fixedly connected to the push long shaft 73, the vertical plate is fixedly connected to the bearing, and the vertical plate is perpendicular to the push long shaft 73, and the end of the push long shaft 73 away from the steam curing chamber 11 is transmission-connected to a rotation drive mechanism 79 that can control the push long shaft 73 to rotate a certain angle, so that the pulling claw 74 can have at least two positions, one of which is a working position. In the working position, the highest point of the pulling claw 74 is higher than the highest point of the wheel surface of the plate feeding wheel 63, so as to push or pull the manure leaking board and the support plate. The other position is the avoiding position. In the avoiding position, the highest point of the pulling claw 74 is lower than the highest point of the wheel surface of the plate feeding wheel 63, so as to avoid interfering with the action of the plate feeding mechanism 6. The rotating drive mechanism 79 adopts a chain transmission form, and can also adopt a gear transmission form, etc. The third reduction motor that drives the sprocket or gear to rotate is fixed at the bottom of the pushing slide bar 72, the driving sprocket or driving gear is connected to the output shaft of the third reduction motor, and the driven sprocket or driven gear is connected to the pushing long shaft 73.

[0102] Furthermore, if Figure 11As shown in the figure, each plate feeding mechanism 6 includes a first reduction motor 61, a plate feeding drive wheel 62, and a plurality of plate feeding supporting wheels 63 arranged in the front-rear direction. The first reduction motor 61 is installed on the lifting platform 4 through a first motor bracket. The output shaft of the first reduction motor 61 is in transmission connection with the plate feeding drive wheel 62. The numbers of the first reduction motor 61 and the plate feeding drive wheel 62 can be selected according to actual working conditions such as the weight of the transported fecal leakage plates. The plate feeding supporting wheels 63 are evenly installed on the lifting platform 4 through supporting wheel brackets. The axes of the plate feeding drive wheel 62 and the plate feeding supporting wheels 63 are both horizontally arranged from left to right. The outer ring of the wheel surface of the plate feeding drive wheel 62 is provided with friction lines to increase the friction force of plate feeding. The outer edge of the wheel surface of the plate feeding supporting wheel 63 is provided with a retaining edge step to prevent the fecal leakage plate and the supporting plate from deviating from the transporting direction of the plate feeding supporting wheel 63.

[0103] Furthermore, the first motor bracket includes a motor base, a motor adjustment seat 64, and an adjustment bolt 65. The motor base is fixed on the lifting platform 4. The first reduction motor 61 is fixed on the motor adjustment seat 64. Hinge seats 66 are fixedly arranged on both the motor base and the motor adjustment seat 64. The motor base and the motor adjustment seat 64 are hinged through the hinge seats 66. The bottom end of the adjustment bolt 65 is fixed on the motor base. The top end of the adjustment bolt 65 extends out of the motor adjustment seat 64 and adjustment nuts are screwed on the upper and lower sides of the motor adjustment seat 64 respectively (alternatively, only the adjustment nut can be screwed on the upper side of the motor adjustment seat 64, and a compression spring is installed between the motor adjustment seat 64 and the motor base to prevent the motor adjustment seat 64 from tilting excessively).

[0104] By changing the relative positions of the adjustment nuts and the adjustment bolt 65, the inclination angle of the motor adjustment seat 64 can be adjusted, so as to adjust the highest position of the wheel surface of the plate feeding drive wheel 62, which is convenient for better driving the fecal leakage plate and the supporting plate. In addition, when the plate feeding drive wheel 62 is worn after long-term use, the highest position of the wheel surface of the plate feeding drive wheel 62 can also be changed through this adjustment method, effectively extending the service life and saving material costs, maintenance costs, etc.

[0105] Furthermore, a top plate 22 is fixed to the top of the gantry upright frame 21, and the lifting mechanism 3 is installed on the top plate 22, as Figure 6As shown in the figure, the lifting mechanism 3 includes a trolley track 32, a moving trolley 33, a fixed support 34, and a lifting hydraulic cylinder 35. Two trolley tracks 32 are symmetrically arranged and fixed on the top plate 22. In this embodiment, the extending direction of the trolley track 32 is the front-rear direction. The moving trolley 33 moves along the trolley track 32 through trolley wheels 36. The fixed support 34 is fixed at one end of the trolley track 32. The cylinder block and the telescopic rod of the lifting hydraulic cylinder 35 are respectively hinged to the fixed support 34 and the moving trolley 33. A plurality of first rope wheels 37 are installed on the moving trolley 33, and a plurality of second rope wheels 38 are installed on the fixed support 34. Guide rope wheels 39 are respectively installed at the four corners of the top plate 22. One end of the steel wire rope 31 is fixed to the moving trolley 33. After the other end of the steel wire rope 31 sequentially bypasses the second rope wheel 38, the first rope wheel 37 and then returns to the second rope wheel 38, it then bypasses the guide rope wheel 39 and is connected to the lifting platform 4.

[0106] The lifting mechanism 3 adopts the form of a hydraulic cylinder driving the trolley to change the length of the steel wire rope 31, which can make the overall movement more stable, and the failure rate of each component is also significantly reduced.

[0107] Further, four steel wire ropes 31 are provided and are symmetrically arranged in pairs. Two of the steel wire ropes 31 are shorter in length and are wound around the second rope wheel 38 and the first rope wheel 37 located on the inner side. The other two steel wire ropes 31 are longer in length and are wound around the second rope wheel 38 and the first rope wheel 37 located on the outer side. The other ends of the respective steel wire ropes 31 are respectively connected to the four corners of the lifting platform 4 through rope wedges.

[0108] Further, the lifting platform 4 includes a cross beam 41 and a longitudinal beam 42 that are perpendicular to each other in the horizontal plane. A plurality of plate feeding rollers 63 of the plate feeding mechanism 6 are evenly installed on the longitudinal beam 42. As Figure 11 shown, a retaining component for limiting the fecal leakage plate and the supporting plate within the lifting platform 4 is installed on the cross beam 41 on the side away from the steam curing chamber 11. The retaining component includes a retaining claw 45 and a push rod 46. A retaining installation groove is formed on the cross beam 41. The retaining claw 45 is rotatably connected in the retaining installation groove. A vertically arranged push rod groove 46 is formed on the cross beam 41 below the retaining installation groove. The push rod groove 46 is communicated with the retaining installation groove. The push rod 46 is slidably connected in the push rod groove 46. When the retaining claw 45 is in the vertical state, the highest point of the retaining claw 45 is higher than the highest point of the wheel surface of the plate feeding roller 63, so as to be able to block the fecal leakage plate and the supporting plate. Taking the rotation axis of the retaining claw 45 as the upper and lower boundary, the lower part of the retaining claw 45 is heavier than the upper part of the retaining claw 45. When no external force is applied, the retaining claw 45 can naturally maintain the vertical state to achieve the retaining function. When it is necessary to move the fecal leakage plate and the supporting plate into the lifting platform 4 from the outside or move them out of the lifting platform 4 to the outside, control the push rod 46 to push the retaining claw 45 upward and make the retaining claw 45 rotate, then the highest point of the retaining claw 45 can be lowered to create a moving space.

[0109] In this embodiment, one side of the anti-reverse claw 45 facing the steam curing chamber 11 includes an anti-reverse plane and a jacking inclined plane. The anti-reverse plane can maintain a relatively large contact area with the feces leakage plate and the supporting plate that needs to be anti-reversed, better realizing the anti-reverse function. The jacking inclined plane corresponds to the jacking rod 46. When the jacking rod 46 needs to jack up the anti-reverse claw 45, the setting of the jacking inclined plane is more conducive to the application of force by the jacking rod 46.

[0110] Furthermore, as Figure 17 shown, a platform positioning assembly 5 is further provided between the gantry upright frame 21 and the lifting platform 4. The platform positioning assembly 5 includes a platform positioning rotating shaft 51, a platform positioning hydraulic cylinder 52, a rocker 53, a rocker arm 54, a long connecting rod 55, a platform positioning rod 56, and a positioning rod sliding seat 57. The platform positioning rotating shaft 51 is rotatably connected to the bottom of the lifting platform 4 through a bearing. The rocker 53 and the rocker arm 54 are both fixedly connected to the platform positioning rotating shaft 51, and the rocker 53 and the rocker arm 54 are respectively perpendicular to the axis of the platform positioning rotating shaft 51. The cylinder seat and the telescopic rod of the platform positioning hydraulic cylinder 52 are respectively hinged to the bottom of the lifting platform 4 and the rocker 53. The long connecting rod 55 is hinged between the rocker arm 54 and the platform positioning rod 56. The positioning rod sliding seat 57 is fixed to the bottom of the lifting platform 4, and the platform positioning rod 56 is horizontally slidably connected within the positioning rod sliding seat 57. A positioning rod chute is fixed on the gantry upright frame 21, and a plurality of positioning platforms are fixed in the height direction of the positioning rod chute. When the platform positioning rod 56 extends out and supports on the positioning platform, the lifting platform 4 is positioned in the height direction. In this example, a height adjusting member capable of adjusting the positioning height of the lifting platform 4 is further installed on the positioning platform. The height adjusting member can be a bolt threadedly connected to the positioning platform. At this time, the top plane of the bolt is the positioning support plane in contact with the platform positioning rod 56.

[0111] To save space, the steam curing chamber 11 can be set as a multi-layer structure. The lifting platform 4 can move up and down within the space below the gantry upright frame 21 driven by the lifting mechanism 3 so as to be adjusted to different heights to correspond to the storage spaces of the steam curing chambers 11 at different heights. When the lifting mechanism 3 moves the lifting platform 4 to a certain appropriate height, the lifting platform 4 can be positioned in the height direction through the platform positioning assembly 5.

[0112] The positioning process of the platform positioning assembly 5 is as follows: When the lifting mechanism 3 stops working, the platform positioning hydraulic cylinder 52 drives the rocker 53 to act, thereby causing the platform positioning rotating shaft 51 to rotate. The rocker arm 54 fixed to the platform positioning rotating shaft 51 can make the platform positioning rod 56 slide along the positioning rod sliding seat 57 through the long connecting rod 55. When the platform positioning rod 56 extends out and supports on the surface of the positioning platform (when a bolt is installed on the positioning platform as the height adjusting member, the platform positioning rod 56 supports on the top plane of the bolt), the lifting platform 4 can be kept at this height unchanged.

[0113] On the other hand, the platform positioning component 5 also has the function of preventing falling. If the lifting mechanism 3 fails due to component damage or other reasons during the upward movement of the lifting platform 4 driven by the lifting mechanism 3, so that the lifting platform 4 falls, the setting of the platform positioning rod 56 and the positioning table can make the lifting platform 4 stop when it reaches the height of the positioning table, avoiding the lifting platform 4 falling to the bottom, and further avoiding the further occurrence of serious accidents.

[0114] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention all belong to the protection scope of the technical solution of the present invention.
