ALC board gradient hoisting and pulling device and method

Abstract

This application relates to a gradient lifting and rod removal device and method for ALC (Alternating Current Carbide) sheets, belonging to the field of ALC sheet processing. It includes a rod removal drive mechanism, a rod removal frame, and a rod removal structure. The drive mechanism is connected to the rod removal frame and can drive the frame to lift. The rod removal structure is mounted on the frame and can be positioned below a saddle to provide rod removal support. Driven by the drive mechanism, the rod removal structure lifts the saddles one by one. This application has the advantage of first applying force to the rods of the lowest saddle, causing them to loosen slowly and release localized adhesion, and then gradually applying force to the next group. This allows the internal stress of the ALC sheet to be gradually dispersed and released, reducing concentrated stress points, lowering the risk of defects such as chipped corners and through cracks in the ALC sheet, and improving the yield rate of ALC sheets.

Description

Technical Field

[0001] This application relates to the field of ALC sheet processing, and in particular to a gradient lifting and brazing device and method for ALC sheets. Background Technology

[0002] ALC panels, short for autoclaved aerated concrete panels, are a new type of lightweight wall material made from cement, lime, sand, and other raw materials, with the addition of a foaming agent, through mixing, pouring, curing, and autoclaving. They possess the characteristics of being lightweight and high-strength, much lighter than traditional brick walls, and offering convenient and efficient construction. They also boast excellent thermal insulation, fire resistance, and sound insulation properties, and are environmentally friendly and recyclable, greatly contributing to improved building energy efficiency and living comfort. They can be widely used in the interior and exterior walls of residential and commercial buildings, as well as in floor slabs, roof panels, and firewalls, making them a popular new building material in green building today.

[0003] In the production process of ALC (Alternating Current Carbide) sheets, steel rods are connected to the reinforcing mesh by welding or clipping to form a rigid frame. After the ALC sheets are poured, the steel rods need to be removed using saddle frames. The existing method of removing the steel rods involves pulling them out simultaneously from multiple saddle frames. However, due to slight differences in the adhesion and insertion depth between different steel rods and the ALC slurry, pulling the steel rods upwards can cause excessive stress on tightly bonded rods and insufficient stress on loosely bonded rods, resulting in excessive local tension. This increases the risk of defects such as chipped corners and through cracks in the ALC sheets, leading to a low yield rate. Summary of the Invention

[0004] To address the issue of excessive local tension between the steel rod and the ALC sheet caused by simultaneous removal of the steel rod, resulting in a low yield rate of the ALC sheet, this application provides a gradient lifting and rod removal device and method for ALC sheets.

[0005] The gradient lifting and rod pulling device for ALC plates provided in this application adopts the following technical solution: A gradient lifting and pin-pulling device for ALC plates includes a pin-pulling drive mechanism, a pin-pulling frame, and a pin-pulling structure. The pin-pulling drive mechanism is connected to the pin-pulling frame and can drive the pin-pulling frame to lift. The pin-pulling structure is disposed on the pin-pulling frame and can be placed below the saddle to form a pin-pulling support for the saddle. The pin-pulling structure can lift the saddle one by one under the drive of the pin-pulling drive mechanism.

[0006] By adopting the above technical solution, when performing the rod removal operation on ALC plates, the rod removal structure is first placed below the saddle, and the rod removal drive mechanism drives the rod removal frame to rise. The rod removal frame drives the saddle to rise one by one through the rod removal structure until the rod is completely separated from the ALC plate. Then, the removed saddle and rod are collected, thus completing the rod removal operation on the ALC plate. Compared with the existing technology of removing rods at the same time, this application can apply force to the rods of the lowest saddle first by raising the saddle one by one through the rod removal structure, so that the rods of the lowest saddle can be loosened slowly and the local adhesive force can be released. Then, the force can be gradually applied to the next group, so that the internal stress of the ALC plate can be gradually dispersed and released, reducing the concentrated stress points, reducing the risk of defects such as corner chipping and through cracks in the ALC plate, and improving the pass rate of ALC plates.

[0007] Preferably, there are two sets of the rod puller, each set of rod puller corresponding to one end of the saddle frame, and the rod puller structure corresponds one-to-one with the rod puller.

[0008] By adopting the above technical solution, two sets of rod pullers can be used to apply rod puller force from both ends of the saddle during the rod puller process, making the rod puller force distribution more uniform and improving the stability of the saddle during the rod puller process.

[0009] Preferably, the rod-pulling structure includes a support portion corresponding to the saddle frame, the support portion being able to drive the saddle frame to pull the rod out of the ALC plate, and each support portion is at a different height.

[0010] By adopting the above technical solution, and utilizing the one-to-one correspondence between the support and the saddle with different vertical spacing, the force applied to the saddle during the rod removal can be sequential, allowing the rod to be removed in a gradient. The structure is simple, making it easy to control the order of rod removal, and further accurately disperses and releases the internal stress of the ALC plate, effectively reducing concentrated stress points.

[0011] Preferably, it further includes a base frame and a rotation drive mechanism. Each of the puller frames is rotatably connected to the base frame. The base frame is connected to the puller drive mechanism. The rotation drive mechanism is disposed on the base frame and connected to the puller frame. The rotation drive mechanism can drive the puller frame to rotate so that the puller structure can support and detach from the saddle frame.

[0012] By adopting the above technical solution, the rotating drive mechanism can drive the rod pulling frame to rotate, enabling the rod pulling structure to flexibly support and detach the saddle frame. This facilitates the processing of the saddle frame and rod at different stages, improves the operational flexibility and applicability of the rod pulling device, and optimizes the rod pulling process of ALC plates.

[0013] Preferably, the rod pulling frame includes a support rod, a tail rod, and a connecting plate. The support rod and the tail rod are fixedly connected by a plurality of the connecting plates. The rod pulling structure is located on the support rod. The tail rod is connected to the rotation drive mechanism. The connecting plate is rotatably connected to the base frame through a rotation shaft.

[0014] By adopting the above technical solution, the support rod and tail rod of the rod extraction frame are fixedly connected by the connecting plate, which can ensure the stability of the rod extraction frame structure. The space between the connecting plates can provide space for the saddle to be inserted, improving the convenience of the rod extraction process.

[0015] Preferably, a chain plate is slidably provided on the support rod, a first chain is wound around the chain plate, a first sprocket is provided on the chain plate that can drive the first chain to rotate, the first chain can drive the saddle to move to the connecting plate, a linear drive mechanism is provided on the connecting plate, the linear drive mechanism is connected to the chain plate and can drive the first chain to support the saddle.

[0016] By adopting the above technical solution, after the rod pulling operation is completed, the linear drive mechanism drives the chain plate to lift, so that the first chain supports the saddle frame and the saddle frame is separated from the support part. Then, the first chain rotates to move the saddle frame to the connecting plate, which facilitates the subsequent handling and collection of the saddle frame. This improves the automation level of the rod pulling device in handling the saddle frame and increases work efficiency.

[0017] Preferably, it also includes a conveying component and a collecting component. The conveying component is disposed on the base frame and is capable of moving the saddle at the connecting plate to the collecting component. The collecting component is disposed on the frame and collects the saddle.

[0018] By adopting the above technical solution, the saddle frame at the moving connecting plate is moved to the collection component using the handling component, and then multiple cases are collected by the collection component. This enables the automatic handling and collection of the removed saddle frame and steel rod, improving the overall automation level and work efficiency of the rod removal operation.

[0019] Preferably, there are two sets of transport components, with an installation space formed between two adjacent connecting plates. Each set of transport components includes a guide plate, a chain drive mechanism, and a fork. The guide plate is located at the bottom of the base frame and above the saddle frame. The guide plate is provided with sliding blocks, each corresponding to a different installation space. The chain drive mechanism is connected to the sliding blocks to drive them to slide cyclically on the guide plate. The fork corresponds to and is connected to each sliding block. The fork has a transport groove with an opening facing the saddle frame, into which the saddle frame can be inserted. Each guide plate is connected to the base frame via a lifting mechanism, which drives the fork to lift, thereby disengaging the saddle frame from the puller frame.

[0020] By adopting the above technical solution, during the handling of the saddle frame, the lifting mechanism drives the guide plate to descend, aligning the handling slot on the fork with the saddle frame. Then, the chain drive mechanism drives the fork to move, inserting the saddle frame into the handling slot. Next, the lifting mechanism drives the saddle frame to rise, disengaging it from the rod puller. The rotation drive mechanism drives the rod puller to rotate, moving it from the side of the saddle frame to above it. At this point, the fork provides support for the saddle frame. The chain drive mechanism then drives the fork to move, moving the saddle frame to the collecting assembly. This achieves efficient handling of the saddle frame, avoiding the low efficiency and high labor intensity of manual handling, and improving the overall working efficiency of the rod puller.

[0021] Preferably, the collecting component includes a conveyor belt mechanism and a linear motion mechanism. The conveyor belt mechanism is slidably connected to the frame. The first linear motion mechanism is connected to the conveyor belt mechanism so as to move the conveyor belt mechanism to below the guide plate. The lifting mechanism can drive the saddle to move onto the conveyor belt mechanism and disengage from the fork. The moving speed of the saddle on the conveyor belt mechanism is greater than the moving speed of the fork.

[0022] By adopting the above technical solution, the linear movement mechanism moves the conveyor belt mechanism to below the guide plate, and the lifting mechanism transfers the saddle from the forklift to the conveyor belt mechanism. The saddle moves faster on the conveyor belt than the forklift, which enables efficient transfer and continuous collection of the saddle, improving the efficiency of saddle collection after ALC plate rod removal.

[0023] A gradient lifting and rod removal method for ALC plates, using the aforementioned ALC plate gradient lifting and rod removal device, includes the following steps: S1 Equipment inspection and rod condition assessment, checking the condition of the removal drive mechanism, rod removal frame, and rod removal structure, checking the tightness of the rod connections, and predicting the removal difficulty; S2 Placing the rod removal mechanism below the saddle frame; S3 The removal drive mechanism drives the rod removal frame to lift, and the rod removal frame drives the saddle frame to lift one by one through the rod removal structure until the rod is completely separated from the ALC plate; S4 Collecting the removed saddle frame and rod.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a rod-pulling structure to lift the saddle frame one by one, the rods on multiple saddle frames are not subjected to force at the same time. This allows the internal stress of the ALC board to be distributed and released, preventing excessive local stress and effectively reducing the possibility of problems such as corner chipping and through cracks in the ALC board, thereby improving the production quality of ALC boards. 2. By utilizing the one-to-one correspondence between the support parts and the saddle frame with different vertical spacing, the force applied to the saddle frame during the extraction of the steel rod can be sequential, allowing the steel rod to be extracted in a gradient. The structure is simple and easy to control the order in which the steel rod is extracted. 3. After the saddle is removed, the first chain rotates, causing the saddle to move to the connecting plate. The chain drive mechanism drives the fork to move, and the fork moves the saddle at the connecting point to the conveyor belt mechanism. The lifting mechanism transfers the saddle from the fork to the conveyor belt mechanism, and the saddle moves faster on the conveyor belt than the fork, so that the saddle is transferred from the fork to the conveyor belt mechanism for collection. This achieves efficient handling of the saddle, avoids the low efficiency and high labor intensity of manual handling, and improves the overall working efficiency of the saddle removal device.

[0041] The following will be combined with the appendix Figures 1-15 The technical solutions in the embodiments of the present invention are further described in detail below. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Those skilled in the art can certainly combine the embodiments of the present invention to obtain other embodiments without creative effort, which are also within the protection scope of the present invention.

[0042] This application mainly adopts a rod pulling structure 3 to lift the saddle frame 61 one by one for rod pulling, which achieves the effect of dispersing and releasing the internal stress of the ALC board, reducing the risk of board defects, and improving the pass rate. The following is a further detailed description of this application. Example 1

[0043] Reference Figure 1 , Figure 2A gradient lifting and rod pulling device for ALC sheet metal includes a rod pulling drive mechanism 1, rod pulling frames 2, rod pulling structures 3, a base frame 4, and a rotation drive mechanism 5, all mounted on a frame. The rod pulling drive mechanism 1 is connected to the base frame 4 and can drive the base frame 4 to move up and down. There are two rod pulling frames 2, each rotatably mounted on one side of the base frame 4. The rotation drive mechanism 5 is mounted on the base frame 4, connected to the rod pulling frames 2, and used to drive the rod pulling frames 2 to rotate. The rod pulling structures 3 correspond one-to-one with the rod pulling frames 2. Set on the corresponding pin-pulling frame 2, each set of pin-pulling structures 3 can rotate with the pin-pulling frame 2 to the lower part of the saddle 61 extending out of the mold. The two sets of pin-pulling structures 3 are respectively located below the end of the mold extending out of the saddle 61. The removal drive mechanism 1 drives the base frame 4 to lift. The pin-pulling structures 3 can lift the saddle 61 one by one. Here, "one by one" means that there is a time difference. It can first apply force to the steel pin 62 of the lowest saddle 61 to make it slowly loosen and release the local adhesive force, and then gradually apply it to the next set. This allows the internal stress of the ALC board to be gradually dispersed and released, reducing the concentrated stress points, reducing the risk of defects such as corner chipping and through cracks in the ALC board, and improving the pass rate of ALC board.

[0044] The removal drive mechanism 1 includes a gantry crane 11 and a winch 12. The gantry crane 11 is located on the top of the frame, and the winch 12 is located on the gantry crane 11. The end of the rope of the winch 12 is fixedly connected to the base frame 4. There are four fixing points between the rope and the base frame 4. The four fixing points are symmetrically arranged to ensure the stability of the base frame 4 during lifting and moving. The winch 12 drives the lifting and lowering of the base frame 4 to provide driving force for the removal of the steel rod 62. The gantry crane 11 drives the base frame 4 to move horizontally.

[0045] Reference Figure 2 , Figure 3 In this embodiment, the rod pulling frame 2 includes a support rod 21, a tail rod 22, and a connecting plate 23. A rotating shaft 24 corresponding to the rod pulling frame 2 is passed through the base frame 4. The rotating shaft 24 is rotatably connected to the base frame 4. The support rod 21 is arranged parallel to the rotating shaft 24 at intervals. The support rod 21 and the rotating shaft 24 are fixedly connected by several connecting plates 23. The several connecting plates 23 are arranged parallel to each other at intervals. There are two tail rods 22. The two tail rods 22 are fixedly connected to two of the connecting plates 23 respectively.

[0046] Reference Figure 2 , Figure 4In this embodiment, the puller structure 3 includes several support parts 31, which are all mounted on the support rod 21. Each support part 31 on the support rod 21 corresponds to a saddle frame 61. Since the saddle frames 61 are at the same height in this embodiment, both ends of each support part 31 are fixedly connected to the support rod 21 through a steel frame. Each support part 31 and the support rod 21 are arranged in parallel. The distance between the support part 31 and the support rod 21 gradually increases from one end of the support rod 21 to the other end, so that the support part 31 is arranged in a stepped shape.

[0047] Reference Figure 2 , Figure 3 The rotation drive mechanism 5 includes a first linear hydraulic cylinder 51. Each rod puller 2 corresponds to two first linear hydraulic cylinders 51 in a group. The two first linear hydraulic cylinders 51 in the same group are arranged in parallel. The cylinder body of each first linear hydraulic cylinder 51 is hinged to the base frame 4 through a hinge seat. The piston rod of the first linear hydraulic cylinder 51 is hinged to the tail rod 22 of the rod puller 2 through a hinge seat. The extension and retraction of the first linear hydraulic cylinder 51 drives the rod puller 2 to rotate around the rotation axis 24. When no rod pulling action is performed, the angle between the connecting plate 23 and the vertical direction reaches its maximum. At this time, the support rod 21 is at its highest position. When the rod 62 is pulled out, the first linear hydraulic cylinder 51 extends and drives the support rod 21 to rotate around the rotation axis 24. 4. Rotate downwards, so that the support part 31 moves from the side of the saddle 61 to directly below the corresponding saddle 61. Then, the winch 12 drives the base frame 4 to lift, and the base frame 4 drives the support part 31 to lift. The support part 31 at the highest position lifts the saddle 61 first. Then, as the base frame 4 continues to lift, the remaining saddles 61 are lifted and removed in sequence until the steel rod 62 is completely removed from the ALC plate, completing the removal of the steel rod 62. By removing the steel rod 62 in sequence, the steel rods 62 on multiple saddles 61 are prevented from being stressed at the same time, allowing the internal stress of the ALC plate to be dispersed and released, preventing excessive local stress, effectively reducing the possibility of problems such as corner chipping and through cracks in the ALC plate, and improving the production quality of the ALC plate.

[0048] The implementation principle of Example 1 is as follows: During the removal of the steel rod 62, the first linear hydraulic cylinder 51 extends and drives the support rod 21 to rotate downward around the rotating shaft 24, so that the support part 31 rotates from the side of the saddle 61 to directly below the corresponding saddle 61. Then, the winch 12 drives the base frame 4 to lift, and the base frame 4 drives the support part 31 to lift. The support part 31 at the highest position lifts the saddle 61 first. Then, as the base frame 4 continues to lift, the remaining saddles 61 are lifted and removed in sequence until the steel rod 62 is completely removed from the ALC plate, thus completing the removal of the steel rod 62. By lifting the saddle 61, the steel rod 62 is removed row by row, so that the stress inside the steel rod 62 and the ALC plate is dispersed and released, improving the production quality of the ALC plate. Example 2

[0049] Reference Figure 5 , Figure 5 The difference between this embodiment and embodiment 1 is that an installation space 25 is formed between two adjacent connecting plates 23. In this embodiment, the number of saddle frames 61 is the same as the number of installation spaces 25. The support parts 31 correspond one-to-one with the installation spaces 25. When the steel rod 62 is removed, the saddle frame 61 is inserted into the installation space 25 and overlaps the support part 31 corresponding to the installation space 25.

[0050] Reference Figure 6 , Figure 7 Both connecting plates 23 are provided with linear drive mechanisms 75. In this embodiment, the linear drive mechanism 75 is a second linear hydraulic cylinder 751. The cylinder body of the second linear hydraulic cylinder 751 is fixedly connected to the connecting plate 23. A chain plate 71 is slidably provided on the inner side of each support rod 21. The chain plate 71 is arranged along the length direction of the support rod 21. The chain plate 71 and the piston rod of each second linear hydraulic cylinder 751 are fixedly connected by a connecting block 76.

[0051] Reference Figure 6 , Figure 8 and Figure 9 Both ends of the chain plate 71 are rotatably fitted with first sprockets 72, and the two first sprockets 72 are connected by a ring-shaped first chain 73. The first chain 73 slides on the side wall of the chain plate 71, so that the chain plate 71 provides sliding support for the first chain 73. One of the first sprockets 72 is connected to a first rotary motor 74 mounted on the chain plate 71, and the first rotary motor 74 drives the first sprocket 72 to rotate. The second linear hydraulic cylinder 751 can drive the chain plate 71 to move vertically, thereby raising the saddle frame 61 above the support rod 21, so that the saddle frame 61 disengages from the support rod 21.

[0052] When the support part 31 lifts the saddle frame 61, the first chain 73 is located below the lowest position of the support part 31, which avoids the first chain 73 from exerting a supporting force on the saddle frame 61, reduces the crushing damage of the first chain 73 on the surface of the chain plate 71, and improves the stability of the first chain 73 sliding on the chain plate 71. When all the steel rods 62 are removed, the second linear hydraulic cylinder 751 drives the chain plate 71 to lift. The chain plate 71 drives the first chain 73 to lift the saddle frame 61 above the support rod 21, so that the saddle frame 61 is separated from the support part 31. Then, the first rotary motor 74 drives the first chain 73 to slide on the chain plate 71. The first chain 73 moves the saddle frames 61 in each installation space 25 toward the connecting plate 23 in the same direction, and abuts against the connecting plate 23 under the obstruction of the connecting plate 23, thereby completing the collection of each saddle frame 61. The saddle frame 61, together with the steel rods 62, is transferred to the designated position on the base frame 4, which facilitates the subsequent collection of the saddle frame 61 and the steel rods 62.

[0053] Reference Figure 5 , Figure 10 The rod-pulling device in this embodiment also includes a transport component 8 and a collection component 9. There are two sets of transport components 8, which are arranged symmetrically about the vertical plane at the bottom of the base frame 4. The collection component 9 is arranged on the base frame 4. The transport component 8 transports the saddle frame 61 to the designated position to the collection component 9, and the collection component 9 collects the saddle frame 61 to complete the automated collection of the saddle frame 61.

[0054] Reference Figure 10 , Figure 11 In this embodiment, the handling component 8 includes a guide plate 81, a chain drive mechanism 82, and a fork 83. Two sets of lifting mechanisms 84 are fixedly installed on the base frame 4. Each guide plate 81 corresponds to one set of lifting mechanisms 84. Each set of lifting mechanisms 84 includes two third linear hydraulic cylinders 841. The two third linear hydraulic cylinders 841 are spaced apart along the length direction of the guide plate 81. Each third linear hydraulic cylinder 841 is vertically downward. The cylinder body of the third linear hydraulic cylinder 841 is fixedly connected to the base frame 4. The piston rod of the third linear hydraulic cylinder 841 is fixedly connected to both guide plates 81 through a profile. The guide plate 81 and the third linear hydraulic cylinder 841 are inclined.

[0055] Reference Figure 11 , Figure 12 and Figure 13 The guide plate 81 includes a straight plate in the middle and semi-circular plates at both ends. A guide rail 85 is provided on the side surface of the guide plate 81. The guide rail 85 is arranged in a circle around the perimeter of the guide plate 81. A guide groove 86 is provided on the side wall of the guide rail 85. The guide groove 86 is arranged in a circle around the perimeter of the guide rail 85. Each guide plate 81 is provided with a sliding block 87. The sliding block 87 corresponds one-to-one with the saddle frame 61. The sliding block 87 is sleeved on the guide rail 85 and slidably connected to the guide rail 85. The sliding block 87 is provided with a sliding post 88 that cooperates with the guide groove 86. The sliding post 88 is inserted into the guide groove 86 and slidably connected to the guide groove 86. The chain drive mechanism 82 includes a second chain 821 and two second sprockets 822. The two second sprockets 822 are rotatably mounted on two semi-circular plates of the guide plate 81. One of the second sprockets 822 is connected to a second rotating motor 824 mounted on the guide plate 81. The second rotating motor 824 drives the second sprocket 822 to rotate. The two second sprockets 822 are connected by the second chain 821. The second chain 821 slides along the side wall of the guide plate 81. The chain pin 823 of the second chain 821 is fixedly connected to the sliding block 87, so that the second chain 821 drives the sliding block 87 to move while rotating.

[0056] Reference Figure 13 , Figure 14The fork 83 corresponds one-to-one with the sliding block 87. The fork 83 is an L-shaped rod structure. One end of the fork 83 engages with the hinge shaft on the sliding block 87, allowing the fork 83 to be hinged to the sliding block 87. The fork 83 can rotate in the vertical plane around the hinge shaft and remain vertical under its own weight. The two right-angled sides of the fork 83 form a transport groove 831. The distance between two adjacent forks 83 is the same as the distance between two adjacent connecting plates 23, allowing the saddle 61 at the connecting plate 23 to be simultaneously inserted into the transport groove 831 of the fork 83.

[0057] When moving the saddle 61 abutting the connecting plate 23, the second rotary motor 824 first drives the fork 83 to transport it to the corresponding installation space 25. At this time, the fork 83 is above the saddle 61 and located on the lowest side of the guide plate 81. Then, the third linear hydraulic cylinder 841 drives the guide plate 81 to descend, so that the transport groove 831 on the fork 83 aligns with the saddle 61. Then, the second rotary motor 824 drives the fork 83 to move towards the saddle 61, so that the saddle 61 is inserted into the transport groove 831 on the fork 83. The forklift 83 is positioned between the two steel rods 62. The guide plate 81 is lifted by the third linear hydraulic cylinder 841, which lifts the saddle frame 61 and disengages it from the first chain 73. This completes the transfer of the saddle frame 61 from the first chain 73 to the forklift 83. Then, the first linear hydraulic cylinder 51 is driven to retract, and the first linear hydraulic cylinder 51 drives the support rod 21 to flip upward, releasing the obstruction of the connecting plate 23 to the horizontal movement of the saddle frame 61. The second rotary motor 824 then drives the saddle frame 61 to move towards the collecting assembly 9, thus realizing the transport of the saddle frame 61.

[0058] Reference Figure 5 , Figure 15 In this embodiment, the collecting component 9 includes a conveyor belt mechanism 91 and a linear movement mechanism 92. There are two conveyor belt mechanisms 91, which are mounted on a sliding frame 93. The width of each conveyor belt mechanism 91 is smaller than the distance between two adjacent steel rods 62, facilitating the insertion of the conveyor belt mechanism 91 between the two steel rods 62. The sliding frame 93 is slidably mounted on the frame. In this embodiment, the linear movement mechanism 92 is a fourth linear hydraulic cylinder 921. The fourth linear hydraulic cylinder 921 is arranged horizontally, with its cylinder body fixedly connected to the base frame 4 and its other end connected to the sliding frame 93.

[0059] When the base frame 4 lifts the saddle frame 61 above the conveyor belt mechanism 91, the third linear hydraulic cylinder 841 drives the conveyor belt mechanism 91 to extend below the base frame 4. Then, the second rotary motor 824 drives the saddle frame 61 to move above the conveyor belt mechanism 91. At this time, the conveyor belt mechanism 91 is inserted between the two steel rods 62. Then, the third linear hydraulic cylinder 841 drives the saddle frame 61 to descend onto the conveyor belt of the conveyor belt mechanism 91, so that the conveyor belt on the conveyor belt mechanism 91 supports the saddle frame 61. The saddle frame 61 is disengaged from the forklift 83. At the same time, the moving speed of the conveyor belt of the conveyor belt mechanism 91 is set to be greater than the moving speed of the forklift 83. This allows the saddle frame 61 to be transferred from the forklift 83 to the conveyor belt mechanism 91 without stopping the second rotary motor 824, thereby improving the handling efficiency of the saddle frame 61.

[0060] The saddle 61, transferred to the conveyor belt mechanism 91, moves under the drive of the conveyor belt and stops moving when blocked by the baffle on the conveyor belt mechanism 91. After one saddle 61 is transferred, the third hydraulic cylinder drives the guide plate 81 to rise, the second rotary motor 824 drives another saddle 61 to move above the conveyor belt mechanism 91, and then the third linear hydraulic cylinder 841 drives the saddle 61 to fall. The saddle 61 is transferred to the conveyor belt mechanism 91 by the forklift 83. The above operation process is repeated continuously to complete the transfer of all saddles 61 to the conveyor belt mechanism 91 for collection, realizing efficient handling of saddles 61, avoiding the low efficiency and high labor intensity of manual handling, and improving the overall working efficiency of the rod pulling device.

[0061] After detaching from the saddle 61, the fork 83 moves to the highest side of the guide plate 81 under the drive of the second chain 821. The inclined setting of the guide plate 81 balances the space occupied in the horizontal and vertical directions, reducing the space occupied by the handling equipment.

[0062] The saddle frames 61 generated from multiple ALC plate pulling operations can be collected on the conveyor belt mechanism 91. Then, the workers can centrally transport the saddle frames 61 on the conveyor belt mechanism 91 to the rebar cage installation station, avoiding multiple small-batch transports of the saddle frames 61 and improving the transport efficiency of the saddle frames 61.

[0063] The implementation principle of Example 2 is as follows: When all the steel rods 62 are removed, the second linear hydraulic cylinder 751 drives the chain plate 71 to lift. The chain plate 71 drives the first chain 73 to lift the saddle frame 61 above the support rod 21, so that the saddle frame 61 is separated from the support part 31. Then, the first rotating motor 74 drives the first chain 73 to slide on the chain plate 71. The first chain 73 moves the saddle frames 61 in each installation space 25 toward the connecting plate 23 in the same direction, and abuts against the connecting plate 23 under the obstruction of the connecting plate 23.

[0064] The second rotary motor 824 first drives the fork 83 to transport it to the corresponding installation space 25. At this time, the fork 83 is above the saddle 61 and located on the lowest side of the guide plate 81. Then, the third linear hydraulic cylinder 841 drives the guide plate 81 to descend, aligning the transport groove 831 on the fork 83 with the saddle 61. The second rotary motor 824 then drives the fork 83 to move towards the saddle 61, so that the saddle 61 is inserted into the transport groove 831 on the fork 83. At this time, the fork 83 is located between the two steel rods 62. The third linear hydraulic cylinder 841 then drives the guide plate 81 to rise, causing the fork 83 to lift and disengage the saddle 61 from the first chain 73. Finally, the first linear hydraulic cylinder 51 is driven to retract, and the first linear hydraulic cylinder 51 drives the support rod 21 to rotate upward. The connecting plate 23 is released from obstructing the horizontal movement of the saddle 61. The second rotary motor 824 drives the saddle 61 to move above the conveyor belt mechanism 91. The third linear hydraulic cylinder 841 drives the conveyor belt mechanism 91 to extend below the base frame 4. Then, the second rotary motor 824 drives the saddle 61 to move above the conveyor belt mechanism 91. At this time, the conveyor belt mechanism 91 is inserted between the two steel rods 62. The third linear hydraulic cylinder 841 drives the saddle 61 to descend onto the conveyor belt of the conveyor belt mechanism 91, so that the conveyor belt on the conveyor belt mechanism 91 supports the saddle 61. The saddle 61 is disengaged from the fork 83, realizing efficient handling of the saddle 61, avoiding the low efficiency and high labor intensity of manual handling, and improving the overall working efficiency of the rod pulling device. Example 3

[0065] This embodiment provides a gradient lifting and rod removal method for ALC plates, including the following steps: S1 Equipment Inspection and Steel Rod 62 Status Assessment: Inspect the status of the removal drive mechanism 1, the rod removal frame 2, and the rod removal structure 3; check the tightness of the connection of the steel rod 62; and predict the removal difficulty.

[0066] S2 places the rod-pulling mechanism below the saddle 61. The winch 12 drives the base frame 4 to descend above the ALC plate, the first linear hydraulic cylinder 51 extends, and the drive rod 21 flips downward, causing the support part 31 to rotate below the corresponding saddle 61.

[0067] S3 removes the drive mechanism 1, which drives the rod removal frame 2 to lift. The rod removal frame 2, through the rod removal structure 3, lifts the saddle frame 61 one by one until the rod 62 is completely separated from the ALC plate. The winch 12 drives the base frame 4 to lift, and the base frame 4 drives the support part 31 to lift the saddle frame 61, so that the rod 62 gradually separates from the ALC plate. As the base frame 4 is lifted, the rod 62 on the saddle frame 61 is completely removed from the ALC plate.

[0068] S4 collects the removed saddle frame 61 and steel rod 62. The second linear hydraulic cylinder 751 drives the first chain 73 to lift the saddle frame 61 above the support rod 21, disengaging the saddle frame 61 from the support part 31. The first rotary motor 74 moves each saddle frame 61 towards the connecting plate 23 in the same direction via the first chain 73, abutting against the connecting plate 23. The second rotary motor 824 drives the transport fork 83 to transport the saddle frame 61 to the corresponding installation space 25. At this time, the transport fork 83 is above the saddle frame 61. Then, the third linear hydraulic cylinder 841 drives the guide plate 81 to descend, aligning the transport groove 831 on the transport fork 83 with the saddle frame 61. The second rotary motor 824 then drives the transport fork 83 to move towards the saddle frame 61, inserting the saddle frame 61 into the transport groove 831 on the transport fork 83. At this time, the transport fork 83 is between the two steel rods 62. Finally, the third linear hydraulic cylinder 841 drives the guide plate... Lifting 81 causes the forklift 83 to lift the saddle 61, disengaging it from the first chain 73. The first linear hydraulic cylinder 51 drives the support rod 21 to reverse upwards, releasing the obstruction of the connecting plate 23 on the horizontal movement of the saddle 61. The third linear hydraulic cylinder 841 drives the conveyor belt mechanism 91 to extend below the base frame 4. The second rotary motor 824 drives the saddle 61 to move above the conveyor belt mechanism 91. The conveyor belt mechanism 91 is inserted between the two steel rods 62. Then, the third linear hydraulic cylinder 841 drives the saddle 61 to descend onto the conveyor belt of the conveyor belt mechanism 91, so that the conveyor belt on the conveyor belt mechanism 91 supports the saddle 61. The saddle 61 disengages from the forklift 83 and hangs on the conveyor belt mechanism 91. The above process is repeated continuously until all the saddles 61 are arranged on the conveyor belt mechanism 91, realizing the collection of the saddles 61.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
