Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation block production technology, and in particular to a thermal insulation storage structure for thermal insulation block production. Background Technology
[0002] The production process of thermal insulation blocks requires an insulated storage structure, a requirement determined by a combination of factors including material properties, production process requirements, and product quality assurance. The main raw materials of thermal insulation blocks typically include cement, lime, fly ash, and other cementing materials. Their strength development depends on a hydration reaction, which requires a suitable temperature. If the ambient temperature is too low, the hydration reaction will slow down or even stop, leading to insufficient strength gain and a loose internal structure. Sudden temperature changes may cause uneven internal stress, resulting in cracking. An insulated storage structure maintains a stable storage temperature, providing continuous and suitable conditions for the hydration reaction, ensuring the blocks achieve the required strength and a dense structure.
[0003] The basic support structure for storing thermal insulation blocks is the core component ensuring the safe storage, stable load-bearing capacity, and compatibility with the curing environment. It must simultaneously meet four major requirements: load-bearing capacity, space utilization, ease of operation, and compatibility with the thermal insulation environment. The storage racks of the basic support structure for storing thermal insulation blocks allow for layered stacking of blocks, improving space utilization and preventing damage to the bottom layers due to pressure. The storage racks are mostly welded from angle steel or square steel, with a frame height of 2-4m and a layer spacing of 300-600mm. Each layer is covered with steel mesh or wooden pallets.
[0004] In existing technical solutions, unstable connection between pallets and stacking racks is a common hidden danger during the storage of insulation blocks. Unstable connection can cause pallets to tilt or slip when subjected to force, such as when forklifts are handling them or when there is slight ground vibration. If the stacking height exceeds 2 layers, falling blocks may injure operators or damage equipment. Summary of the Invention
[0005] The purpose of this utility model is to provide an insulated storage structure for the production of thermal insulation blocks. By extending the locking plunger, the inclined part of the locking plunger can be engaged with the locking hole of the limiting tray, thus ensuring the stability of the tray during placement and solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an insulation storage structure for the production of insulation blocks, comprising a stacking rack, wherein a limiting plate is fixedly installed on the inner side wall of the stacking rack, and a tray is slidably installed inside the limiting plate;
[0007] The tray is equipped with a dispersion locking assembly, which includes a first cylinder inside the left and right sides of the tray. A locking plunger is slidably installed inside the first cylinder. A locking hole matching the locking plunger is opened on the inner bottom surface of the limiting plate.
[0008] Preferably, the dispersion locking assembly further includes a hydraulic pad fixedly installed on the upper surface of the tray, and the bottom surface of the hydraulic pad is detachably installed with a compression connecting pipe located inside the tray, and the output end of the compression connecting pipe is connected to the first cylinder.
[0009] Preferably, the tray has an unlocking component both inside and outside, and the unlocking component includes two matching plates fixedly installed on the lower end face of the tray.
[0010] Preferably, the matching plate has a hydraulic groove on its inner bottom surface, and an extrusion plate is slidably installed inside the hydraulic groove.
[0011] Preferably, the output end of the hydraulic tank is fixedly connected to a squeezing injection pipe, and the output end of the squeezing injection pipe is connected to a second cylinder located inside the tray.
[0012] Preferably, a compression plunger is slidably installed inside the second cylinder, and the inclined surface of the compression plunger is in contact with and corresponds to the inclined surface of the locking plunger.
[0013] Preferably, fixed wing plates with an X-shaped structure are fixedly installed on the left and right sides of the stacking rack, and a limit block is fixedly installed at the rear end of the limiting support plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model, through the extension of the locking plunger, allows the inclined part of the locking plunger to engage with the locking hole of the limiting plate, thus ensuring the stability of the pallet during placement. When the insulation block is placed on the hydraulic cushion, the pressure generated by the weight of the block will automatically drive the liquid in the hydraulic cushion to flow, pushing the locking plunger to extend and engage with the locking hole of the limiting plate. The entire process does not require manual fixing, avoiding the problem of unstable connection caused by human negligence.
[0016] 2. The hydraulic cushion provided in this utility model can disperse the pressure of the placed insulating bricks. Through the internal fluid flow, the hydraulic cushion transforms the concentrated pressure of the bricks into a uniformly distributed surface pressure, avoiding the damage to the edges and corners of the bricks caused by excessive force at the contact points due to traditional rigid pallets such as steel pallets.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a technical solution:
[0026] Please see Figures 1 to 4A thermal insulation storage structure for thermal insulation blocks includes a storage rack 1. A limiting plate 3 is fixedly installed on the inner side wall of the storage rack 1. A tray 4 is slidably installed inside the limiting plate 3. X-shaped fixed wing plates 2 are fixedly installed on the left and right sides of the storage rack 1. A limiting block is fixedly installed at the rear end of the limiting plate 3. Both the tray 4 and the hydraulic cushion 501 are provided with flow holes 6. The flow holes 6 allow sufficient air circulation around the thermal insulation blocks.
[0027] The tray 4 is equipped with a dispersion locking assembly 5. The dispersion locking assembly 5 includes a first cylinder 503 located inside the left and right sides of the tray 4. A locking plunger 504 is slidably installed inside the first cylinder 503. A locking hole 505 matching the locking plunger 504 is opened on the inner bottom surface of the limiting plate 3. The dispersion locking assembly 5 also includes a hydraulic pad 501 fixedly installed on the upper surface of the tray 4. A compression connecting pipe 502 located inside the tray 4 is detachably installed on the bottom surface of the hydraulic pad 501. The output end of the compression connecting pipe 502 is connected to the first cylinder 503.
[0028] By adopting the above technical solution, during use, a forklift inserts the pallet 4 from the front end of the limiting pallet 3 into the limiting pallet 3. The limiting block at the rear end of the limiting pallet 3 can block and limit the movement, ensuring that the pallet 4 can be placed in the appropriate position within the limiting pallet 3. Simultaneously, when storing the insulation bricks, the insulation bricks can be placed on the hydraulic cushion 501. The hydraulic cushion 501 can distribute the pressure of the placed insulation bricks. Through the internal fluid flow, the hydraulic cushion 501 transforms the concentrated pressure of the bricks into a uniformly distributed surface pressure, preventing damage to the edges and corners of the bricks caused by excessive force at the contact points, which is common with traditional rigid pallets 4 such as steel pallets 4. When the insulation bricks compress the hydraulic cushion 501, the fluid inside the hydraulic cushion 501 will compress and connect... The fluid from the pipe 502 flows into the interior of the first cylinder 503. As the fluid inside the first cylinder 503 increases, it pushes the locking plunger 504 downward, thus pushing the locking plunger 504 out of the tray 4. The extension of the locking plunger 504 allows its inclined portion to engage with the locking hole 505 of the limiting plate 3, ensuring the stability of the tray 4 during placement. When the insulation block is placed on the hydraulic cushion 501, the pressure generated by the block's own weight automatically drives the fluid in the hydraulic cushion 501 to flow, pushing the locking plunger 504 out and engaging with the locking hole 505 of the limiting plate 3. The entire process does not require manual fixing, avoiding connection instability caused by human negligence.
[0029] Specifically, such as Figures 2 to 4As shown, the inner and outer sides of the tray 4 are equipped with an unlocking component 7. The unlocking component 7 includes two matching plates 701 fixedly installed on the lower end face of the tray 4. The inner bottom surface of the matching plate 701 is provided with a hydraulic groove 704. A squeezing plate 702 is slidably installed inside the hydraulic groove 704. The output end of the hydraulic groove 704 is fixedly connected to a squeezing injection pipe 703. The output end of the squeezing injection pipe 703 is connected to a second cylinder 705 opened inside the tray 4. A squeezing plunger 706 is slidably installed inside the second cylinder 705. The inclined surface of the squeezing plunger 706 is in contact with the inclined surface of the locking plunger 504.
[0030] By adopting the above technical solution, when it is necessary to unlock and separate the pallet 4 after the locking connection, the forklift forks lift the matching plate 701 at the bottom of the pallet 4. The weight of the forks and the insulation block itself compresses the compression plate 702 inside the matching plate 701. The contraction of the compression plate 702 compresses the oil inside the hydraulic groove 704, allowing the oil to be delivered to the second cylinder 705 through the compression injection pipe 703. The increase in oil inside the second cylinder 705 compresses the compression plunger 706, causing it to extend out of the second cylinder 705. At this time, the compression plunger 706... The inclined surface, by fitting against the inclined surface of the locking plunger 504, can compress the locking plunger 504 into the first cylinder 503, thereby pulling it out from the locking hole 505. This unlocks the connection between the pallet 4 and the limiting plate 3. It should be noted that during the extension and retraction of the compression plunger 706 and the locking plunger 504, their inclined surfaces are always partially in contact, ensuring that the compression plunger 706 and the locking plunger 504 can push each other. When the forklift forks lift the matching plate 701 at the bottom of the pallet 4, no additional unlocking action is required, such as manually pulling the switch or pressing the button. The compression plate 702 can be triggered to retract simply by the lifting force, thereby driving the hydraulic system to complete the unlocking. The entire process is completely synchronized with the forklift's picking action, eliminating the intermediate steps of "stopping the forklift first → manually unlocking → then continuing to pick up goods" in the traditional unlocking method; at the same time, locking relies on the block's own weight to automatically lock when under load, and unlocking relies on the forklift lifting goods to trigger unlocking, forming a safety logic of "locking when there is goods, unlocking only when goods are picked up", which avoids misunderstanding locking when there is no operation. For example, accidental collisions in non-picking state will not trigger unlocking, reducing the risk of pallet 4 accidentally falling off.
[0031] Working principle: In use, a forklift inserts the pallet 4 from the front end of the limiting pallet 3 into the limiting pallet 3. The limiting block at the rear end of the limiting pallet 3 acts as a blocking and limiting block, ensuring that the pallet 4 can be placed in the appropriate position within the limiting pallet 3. Simultaneously, when storing the insulation bricks, the insulation bricks can be placed on the hydraulic cushion 501. The hydraulic cushion 501 can distribute the pressure of the placed insulation bricks. When the insulation bricks compress the hydraulic cushion 501, the internal pressure of the hydraulic cushion 501... Liquid flows into the first cylinder 503 through the squeeze connecting pipe 502. As the liquid level inside the first cylinder 503 increases, it pushes the locking plunger 504 downwards, thus pushing it out of the tray 4. The extended locking plunger 504 allows its inclined portion to engage with the locking hole 505 of the limiting plate 3, ensuring the stability of the tray 4 during placement. When it is necessary to adjust the locking connection of the tray 4... During unlocking and separation, the forklift forks lift the matching plate 701 at the bottom of pallet 4. The weight of the forks and the insulation block itself compresses the compression plate 702 inside the matching plate 701. The contraction of the compression plate 702 compresses the oil inside the hydraulic tank 704, allowing the oil to be delivered to the second cylinder 705 through the compression injection pipe 703. The increase in oil inside the second cylinder 705 compresses the compression plunger 706, thus causing the compression plunger 706 to... 06 extends out from the second cylinder 705. At this time, the inclined surface of the compression plunger 706, through its contact with the inclined surface of the locking plunger 504, can compress the locking plunger 504 into the first cylinder 503, thereby pulling it out from the locking hole 505, thus unlocking the connection between the tray 4 and the limiting plate 3. It should be noted that during the extension and retraction movement of the compression plunger 706 and the locking plunger 504, their inclined surfaces are always partially in contact, ensuring that the compression plunger 706 and the locking plunger 504 can push each other.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein. Such 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 this utility model.
