Description

Technical Field

[0001] This invention relates to the field of steel structure fencing technology, and specifically to a steel structure fencing based on building energy-saving technology. Background Technology

[0002] Steel structure fencing is widely used in various application scenarios due to its strength, durability, and flexibility. It is commonly used on construction sites as temporary fencing and safety barriers, and is also suitable for prefabricated houses, temporary buildings, and urban infrastructure construction. During routine maintenance or emergency repairs of city streets and roads, construction teams erect fencing of appropriate heights in the construction area; steel structure fencing provides safety isolation and support structures in scenarios requiring temporary, rapid erection, and flexible application.

[0003] During routine maintenance or emergency repairs of city streets and roads, construction teams use steel structure fencing for safety isolation. The erection height of steel structure fencing on general roads should not be less than 1.8 meters, and on major urban roads, it should not be less than 2.5 meters. Depending on the road surface repair or pipeline repair, construction teams need to flexibly adopt steel structure fencing of different heights to balance the isolation function and stability of the steel structure fencing. Existing steel structure fencing usually uses fixed-specification fencing panels, and construction workers lay the fencing panels on fixed supports.

[0004] Generally, the specifications of the fencing panels are designed and finalized during production. When construction workers encounter changes in the required height of the fencing during installation, they need to replace the fencing panels with different specifications before laying them uniformly. This is especially true when adjusting on an already erected fencing base, which requires workers to disassemble and reassemble the panels. This is not only inefficient, but also wastes materials due to the use of multiple specifications of fencing panels, which is detrimental to building energy conservation and will affect the construction process.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs a steel structure fence based on building energy-saving technology, which solves the above technical problems. Summary of the Invention

[0006] The technical objective of this invention is to provide a steel structure fence based on building energy-saving technology, which is an adjustable fence formed by sliding connection of multiple small fence panels. The fence panels use internal pulleys and locking mechanisms to adjust the height of the fence, thereby quickly changing different fence heights.

[0007] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution:

[0008] This invention provides a steel structure fence based on building energy-saving technology, including a fence shell installed on the outer layer of the fence; it also includes a fence body, a pulley assembly, and a hook assembly. The fence body is installed inside the fence shell, and the fence body consists of three fence sliding plates, which are nested together. The pulley assembly is installed on the side of the fence sliding plate, and the hook assembly is installed in the interval between the nested fence sliding plates. The pulley assembly pulls the fixed pulleys in sequence through an internal safety rope, thereby raising the fence sliding plates layer by layer. As the fence sliding plates are raised, the hooks inside the hook assembly slide to the engaging position.

[0009] The outer shell of the hoarding is quickly and easily installed on the outer layer of the hoarding using a snap-fit ​​method. This installation method is simple and quick, requiring no tools or complicated operations. The outer shell provides excellent decoration for the hoarding itself, making it look more beautiful and elegant, while also protecting the hoarding from damage caused by external factors.

[0010] The main body of the fence consists of three sliding panels. Each panel has a groove on its inner wall and a rail on its outer wall. The grooves and rails work together to allow for a nested, sliding installation. This sliding installation method makes the fence easy to fold and unfold, greatly improving installation and dismantling efficiency.

[0011] The pulley assembly includes a turntable main wheel, a fixed tie rod, a low-level pulley, a low-level tie rod, a high-level pulley, a high-level tie rod, and a safety rope. The fencing slide is divided into low-level fencing, middle-level fencing, and high-level fencing from bottom to top. The outer side of the low-level fencing has two vertical meshing grooves, and the outer side of the middle-level fencing has one vertical meshing groove. Hook assemblies are installed in the gap between the inner ends of the low-level and middle-level fencing. The turntable main wheel is installed on the lower outer side of the low-level fencing, and the fixed tie rod is installed on one side of the turntable main wheel. The low-level pulley is installed on the upper outer side of the low-level fence, the low-level tie rod is installed on the lower outer side of the middle-level fence and slidably installed in the meshing groove, the high-level pulley is installed on the upper outer side of the middle-level fence and vertically aligned with the low-level tie rod, the high-level pulley and the low-level pulley are provided with concave mounting ring grooves, the high-level tie rod is installed on the lower outer side of the high-level fence, the safety rope is connected in series with the turntable main wheel, the low-level pulley and the low-level tie rod, and another safety rope is connected in series with the fixed tie rod, the high-level pulley and the high-level tie rod.

[0012] The lower-level fencing is installed on the ground. The middle-level fencing is slidably connected to the inside of the lower-level fencing via a side rail. The upper-level fencing is also slidably installed inside the middle-level fencing. There are two safety ropes, one of fixed length and the other with its head wrapped around the turntable main wheel. More safety rope can be wrapped around the turntable main wheel to facilitate the replacement of the safety rope. The two safety ropes are connected in series with two fixed pulleys. The middle-level fencing and the upper-level fencing slide and rise layer by layer through the linkage of the two fixed pulleys.

[0013] An adjusting rod is coaxially mounted on the inner side of the turntable main wheel. The adjusting rod extends into the lower enclosure and is equipped with a transmission bevel gear. The transmission bevel gear is connected to the adjusting worm gear below the adjusting rod through a transmission gear set. The inner end of the turntable main wheel extends into the lower enclosure and is coaxially mounted with an adjusting worm wheel. The adjusting worm gear meshes with the adjusting worm wheel.

[0014] The mounting groove limits and stabilizes the safety rope through its internal concave end face, allowing the safety rope to slide stably on the pulley. The mounting groove consists of two grooves that can stagger the two pulleys to connect the safety ropes, thus preventing interference between the safety ropes.

[0015] The rotation of the transmission bevel gear and the transmission gear set allows the rotational force of the adjusting rod to be smoothly transmitted to the worm gear mechanism, thereby achieving continuous, unidirectional, and stable lifting of the hoarding slide. Considering the large width of the hoarding slide, it is difficult to maintain torque balance by manually adjusting with a single adjusting shaft, and it is also quite strenuous for operators to directly rotate the turntable main wheel. Under the gravity of the hoarding slide, the positions of the middle and upper hoardings will slide down, resulting in inaccurate overall lifting height of the hoarding slide. The transmission gear set includes a bevel gear meshing with the transmission bevel gear. This bevel gear is connected to a gear set consisting of three spur gears through a transmission shaft, transmitting power to the adjusting worm, thereby achieving precise torque transmission and continuous self-locking. This ensures that workers can adjust the adjusting rod more effortlessly and accurately to the specified height.

[0016] A lifting rack is installed at the inner left end of the engagement groove, and a braking rack is installed at the outer right end of the engagement groove. The brake rack has ratchet teeth, and the lifting rack and brake rack are staggered inside and outside. In case of breakage of the safety rope, the brake rack engages with the locking block to brake the sliding plate in an emergency, improving the safety and reliability of the pulley assembly.

[0017] The outer end of the lifting rack has a sliding end face, the plane height of which is not lower than the height of the addendum circle of the lifting rack. The inner end of the brake rack has a sliding groove, the width of which is equal to that of the lifting rack, and the sliding groove is right-angled. The sliding end face is crucial for supporting and limiting the lower tie rod, ensuring its stable sliding and thus ensuring that the lifting gear has sufficient space to rotate and mesh. The height of the sliding end face must not be lower than the height of the addendum circle of the lifting rack to ensure that the lower tie rod fits tightly against the sliding end face, making the movement of internal parts more compact and stable.

[0018] A lifting gear is installed at the inner end of the lower-level tie rod. The inner end of the lifting gear is rotatably connected to the middle-level enclosure. The lifting gear meshes with the lifting rack. A lifting groove is opened on the end face of the lifting gear. A lifting slide rod is installed in the lifting groove. The lifting slide rod is connected to the brake block through the lifting connecting rod. The brake block is horizontally slidably installed. The front end of the brake block is wedge-shaped and points to one side of the brake rack. The outer end of the lifting slide rod is connected to the lower-level tie rod. The lifting connecting rod is always inclined to the vertical direction.

[0019] A lifting gear is installed at the inner end of the lower-level tie rod, which is precisely connected to the middle-level enclosure and can rotate. The lifting gear meshes tightly with the lifting rack to ensure good performance of the equipment over a long period of use; the brake top block is installed horizontally and its front end is designed in a wedge shape, which can move horizontally and effectively transmit power to the brake rack to achieve emergency braking of the enclosure slide plate.

[0020] The hook assembly includes a chute base, guide blocks, a support plate, and hook guide rods. The chute base is vertically installed on the inner end face of the middle layer of the enclosure. Multiple guide blocks are vertically arrayed inside the chute base. The support plate is horizontally installed inside the lower layer of the enclosure. Hook guide rods are rotatably installed on the support plate. The hook guide rods are slidably installed in the hook chute on the chute base via telescopic guide posts at the lower end. When the telescopic guide posts are aligned with the lowest guide block, the middle layer of the enclosure is pulled up to the highest position.

[0021] The guide block has a straight sliding groove. A hook guide block and an irregularly shaped guide block are installed on one side of the straight sliding groove. The upper end of the hook guide block is a support groove, which is inverted V-shaped. The lower end of the hook guide block divides the straight sliding groove into a guide inclined groove. The irregularly shaped guide block is installed above the support groove.

[0022] The guide block features a straight sliding groove made of high-strength, wear-resistant alloy steel. A hook guide block and a shaped guide block are installed on one side of the straight sliding groove. The upper end of the hook guide block has an inverted V-shaped support groove, and the lower end divides the straight sliding groove into a guide ramp with a slope matching the inverted V-shaped support groove on the hook guide block, ensuring smooth sliding of the hook guide rod within the groove path. The support groove supports the lower telescopic column of the hook guide rod, which hooks onto the guide block through the support groove to achieve a fixed height.

[0023] An irregularly shaped guide block is installed above the support slot. The shape of the guide block is designed to specifically guide the hook guide rod, thus guiding its sliding movement and reducing errors. The hook assembly features a simple structure, convenient operation, and reliable safety, thereby improving the accuracy of the barrier sliding plate height adjustment.

[0024] A reversing pad is installed in the straight slide groove, and a lifting pad is installed in the guide inclined groove. The tails of both the reversing pad and the lifting pad are sloped upwards. The head of the reversing pad is inclined and coincides with the lower inclined surface of the hook guide block. The head of the lifting pad bends along the guide inclined groove and aligns with the inverted V-shaped inclined surface of the support slot. The maximum height of the lifting pad and the reversing pad does not exceed half the depth of the straight slide groove.

[0025] The internal groove design of the guide block optimizes the movement of the hook assembly. The hook guide block, irregularly shaped guide block, and inverted V-shaped support groove ensure smooth sliding and coordination with other components during lifting. The reversing platform and lifting platform help guide the movement direction of the hook guide block and stabilize the action. The maximum height of the platform does not exceed half the depth of the straight groove. If the platform height is too high, the telescopic guide post at the lower end of the hook guide rod will extend and retract more, causing the hook guide rod to slide out of the groove within the guide block, thereby improving the reliability of the hook assembly.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention installs a sliding and lifting hoisting plate on the main body of the hoisting structure. The hoisting plate is raised layer by layer through a pulley assembly, while the lower-level tie rods are quickly and smoothly adjusted in height through the pulley assembly and the tie rod engagement groove, thus making it suitable for hoisting construction at different heights.

[0028] 2. The present invention has a low-level tie rod installed on the pulley assembly. The low-level tie rod slides left and right through the brake top block on it, so as to realize the timely engagement of the brake top block and the brake rack, ensuring that the barrier slider is quickly braked in an emergency, thereby preventing potential accidents from happening.

[0029] 3. The present invention also includes a hook assembly installed inside the main body of the enclosure. By sliding the guide block of the hook assembly upward in conjunction with the rotation of the hook guide rod, the height of the enclosure slide plate is further stabilized. At the same time, the guide groove in the guide block allows the hook guide rod to be unlocked quickly, thereby achieving quick assembly and disassembly. Attached Figure Description

[0044] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0045] like Figures 1 to 11 As shown, a steel structure fence based on building energy-saving technology includes a fence shell 1, which is installed on the outer layer of the fence; it also includes a fence body 2, a pulley assembly 3, and a hook assembly 4. The fence body 2 is installed inside the fence shell 1. The fence body 2 is composed of three fence sliding plates 5, which are nested together. The pulley assembly 3 is installed on the side of the fence sliding plate 5, and the hook assembly 4 is installed in the interval between the nested fence sliding plates 5. The pulley assembly 3 pulls the fixed pulleys in sequence through the internal safety rope 37, thereby raising the fence sliding plates 5 layer by layer. When the fence sliding plates 5 are raised, the hooks inside the hook assembly 4 slide to the engaging position.

[0046] The outer shell 1 of the enclosure is quickly installed on the outer layer of the enclosure by snap-fit. The outer shell 1 serves to provide decoration and protection for the enclosure body. The enclosure body 2 consists of three enclosure sliding plates 5. The enclosure sliding plates 5 cooperate with the sliding rail on the outer wall of another enclosure sliding plate 5 through the sliding groove on the inner wall, thereby realizing the sliding installation of the inner and outer plates nested together. The installation opening position of the sliding groove and the sliding rail is close to the sealed end of the enclosure sliding plate 5, so as to provide a more stable connection.

[0047] The pulley assembly 3 is the main driving device for lifting the three barrier sliding plates 5. The pulley assembly 3 uses two fixed pulleys connected in series. When one set of fixed pulleys is driven to rotate, the other set of fixed pulleys will also move in the same way. According to this motion mechanism, the pulley assembly 3 can use a single power to drive the multi-layer barrier sliding plates 5 to perform telescopic movement. In order to ensure that the load pressure of the sliding assembly is not too large, the barrier sliding plates 5 are composed of lightweight structural steel and aluminum front barrier. The main power drive part uses lightweight and high-strength structural steel for sliding connection to ensure the strength of the main body of the mechanism, while the front end of the barrier isolation function is connected with lightweight aluminum alloy. Under the premise of ensuring the isolation function, the load of the pulley assembly 3 is reduced, and the operating pressure of the workers is also reduced.

[0048] like Figure 2 and Figure 3 As shown, the pulley assembly 3 includes a turntable main wheel 31, a fixed tie rod 32, a low-level pulley 33, a low-level tie rod 34, a high-level pulley 35, a high-level tie rod 36, and a safety rope 37. The enclosure slide plate 5 is divided into a low-level enclosure 51, a middle-level enclosure 52, and a high-level enclosure 53 from bottom to top. The low-level enclosure 51 has two vertical meshing grooves 54 on its outer side, and the middle-level enclosure 52 has one vertical meshing groove 54 on its outer side. The turntable main wheel 31 is installed on the lower outer side of the low-level enclosure 51, and the fixed tie rod 32 is installed on one side of the turntable main wheel 31. The lower pulley 33 is installed on the upper outer side of the lower enclosure 51, the lower tie rod 34 is installed on the lower outer side of the middle enclosure 52 and slidably installed in the meshing groove 54, the upper pulley 35 is installed on the upper outer side of the middle enclosure 52 and aligned vertically with the lower tie rod 34, the upper tie rod 36 is installed on the lower outer side of the upper enclosure 53, the safety rope 37 is connected in series with the turntable main wheel 31, the lower pulley 33 and the lower tie rod 34, and another safety rope 37 is connected in series with the fixed tie rod 32, the upper pulley 35 and the upper tie rod 36.

[0049] The lower-level fencing 51 and the middle-level fencing 52 are the main driving components in the lifting movement. The upper-level fencing 53 only plays a supplementary role in height. The lower-level fencing 51 drives the middle-level fencing 52 to lift, and the middle-level fencing 52 drives the upper-level fencing 53 to lift. Thus, the middle-level fencing 52 and the upper-level fencing 53 will have a sliding stroke in the corresponding driving layer of the fencing. Since the installation between the fencing is a tight sliding connection through the slide rails and grooves, in order to realize the mutual sliding and interlocking between the fencing, the lower-level fencing 51 and the middle-level fencing 52 are provided with meshing grooves 54. The lower-level fencing 51 has two meshing grooves 54 because the lower-level fencing 51 needs to cooperate with both the middle-level fencing 52 and the upper-level fencing 53, while the middle-level fencing only needs to cooperate with the upper-level fencing 53.

[0050] Two safety ropes 37 are included: one of fixed length and the other with its head wound around the turntable main wheel 31. These two safety ropes 37 play a crucial role in the system. One is used to fix the positions of the middle-layer fencing 52 and the upper-layer fencing 53, while the other is wound and unwound by the rotation of the turntable main wheel 31. This design allows for convenient replacement of the safety ropes 37 by winding more ropes around them. The two safety ropes 37 are connected in series to two fixed pulleys, which are also important components of the system. Through a linkage mechanism, the middle-layer fencing 52 and the upper-layer fencing 53 can slide and rise layer by layer. This linkage mechanism ensures the stability and reliability of the system, allowing the fencing to slide and rise accurately. Furthermore, this design improves the system's safety. Because the rolling friction resistance of the fixed pulleys is low, the friction resistance during the fencing sliding and rising process is reduced, thereby minimizing potential damage to the system. Simultaneously, due to the long service life of the fixed pulleys, this design also extends the system's lifespan.

[0051] like Figures 3 to 5 As shown, both the high-level pulley 35 and the low-level pulley 33 have two concave mounting ring grooves 351. An adjusting rod 311 is coaxially and rotatably mounted on the inner side of the turntable main wheel 31. The adjusting rod 311 extends into the interior of the low-level enclosure 51 and is equipped with a transmission bevel gear 312. The transmission bevel gear 312 is connected to the adjusting worm gear 314 below the adjusting rod 311 through a transmission gear set 313. The inner end of the turntable main wheel 31 extends into the interior of the low-level enclosure 51 and is coaxially and synchronously mounted with an adjusting worm gear 315. The adjusting worm gear 314 meshes with the adjusting worm gear 315.

[0052] Considering that construction workers need to manually rotate the adjusting rod 311 to lift the fence, if the turntable main wheel 31 is driven directly, it means that the workers will directly pull the safety rope 37 to lift the two fence sections. This would obviously increase the workers' workload, and at this time, the layers of the fence are still free to slide. Once the workers let go, the fence will fall quickly. Therefore, indirect transmission through the adjusting rod 311 can greatly reduce the workers' workload and work risks.

[0053] like Figure 6As shown, a lifting rack 541 is installed at the inner left end of the meshing groove 54, and a braking rack 542 is installed at the outer right end of the meshing groove 54. The teeth of the braking rack 542 are ratchet-shaped, and the lifting rack 541 and the braking rack 542 are staggered inside and outside. The inner walls of the engagement groove 54 are designed so that when the lower tie rod 34 slides in the engagement groove 54, the side pulled by the safety rope 37 will exert greater pressure on the corresponding side of the engagement groove 54. When the lifting gear 341 is installed at the inner end of the lower tie rod 34, the rotation of the lifting gear 341 will lift the lifting rack 541, thereby driving the middle enclosure 52 to lift. The brake rack 542 on the other side of the engagement groove 54 is used to deal with the emergency situation when the safety rope 37 breaks and the lower tie rod 34 loses tension and slides down. The ratchet-shaped rack of the brake rack 542 cooperates with the corresponding locking block to realize the emergency braking of the enclosure slide plate 5, thereby improving the safety and reliability of the pulley assembly 3.

[0054] like Figure 6 As shown, the outer end of the lifting rack 541 is provided with a sliding end face 543, and the plane height of the sliding end face 543 is not lower than the height of the tooth tip circle of the lifting rack 541; the inner end of the braking rack 542 is provided with a sliding groove 544, the width of the sliding groove 544 is equal to that of the lifting rack 541, and the sliding groove 544 is a right angle.

[0055] The sliding end face 543 is used to support and limit the main body of the lower tie rod 34, thereby ensuring that the lower tie rod 34 can slide stably in the meshing groove 54. At the same time, the lifting gear 341 at the inner end of the lower tie rod 34 has sufficient space to rotate and mesh with the lifting rack 541. The plane height of the sliding end face 543 is not lower than the height of the tooth tip circle of the lifting rack 541. The height of the sliding end face 543 can be appropriately higher than the height of the tooth tip circle of the lifting rack 541, thereby ensuring that while the lifting gear 341 rotates inside the sliding end face 543, the lower tie rod 34 is tightly fitted with the sliding end face 543, making the movement of the parts inside the pulley assembly 3 more compact and stable.

[0056] like Figure 7 and Figure 8As shown, a lifting gear 341 is installed at the inner end of the lower layer tie rod 34. The inner end of the lifting gear 341 is rotatably connected to the middle layer enclosure 52. The lifting gear 341 meshes with the lifting rack 541. A lifting groove 342 is opened on the end face of the lifting gear 341. A lifting slide rod 343 is installed in the lifting groove 342. The lifting slide rod 343 is connected to the brake top block 345 through the lifting connecting rod 344. The brake top block 345 is horizontally slidably installed. The front end of the brake top block 345 is wedge-shaped and points to one side of the brake rack 542. The outer end of the lifting slide rod 343 is connected to the lower layer tie rod 34. The lifting connecting rod 344 is always inclined to the vertical direction.

[0057] The lower layer tie rod 34 is equipped with a lifting gear 341 at its inner end. The inner end of the lifting gear 341 is rotatably connected to the middle layer enclosure 52. This connection allows the lifting gear 341 to rotate as the middle layer enclosure 52 is raised. At the same time, the rotation of the lifting gear 341 on the lifting rack 541 will pull the middle layer enclosure 52 to rise. The two feedback each other, and the lifting gear 341 and the lifting rack 541 are tightly meshed. This meshing method allows the lifting gear 341 to generate rotational motion through the movement of the lifting rack 541.

[0058] The lifting gear 341 has a lifting groove 342 on its end face, providing an optimized sliding path. A lifting rod 343 is installed within the lifting groove 342. The connection between the lifting rod 343 and the lifting connecting rod 344 enables precise control of the brake block 345. The brake block 345 is horizontally slidable, allowing it to slide horizontally. The front end of the brake block 345 is wedge-shaped and points towards one side of the brake rack 542. This design allows the brake block 345 to better engage with the brake rack 542 during sliding.

[0059] The outer end of the lifting slide rod 343 is connected to the lower tie rod 34. This connection allows the movement of the lifting slide rod 343 to be transmitted to the lower tie rod 34. The lifting link 344 is always inclined to the vertical direction. This design allows the lifting link 344 to maintain a stable inclination during operation, thereby enabling the pulley assembly 3 to better transmit force and precisely control the braking and releasing of the enclosure.

[0060] like Figures 9 to 11As shown, the hook assembly 4 includes a sliding base 41, a guide block 42, a support plate 43, and a hook guide rod 44. The sliding base 41 is vertically installed on the inner end face of the middle layer enclosure 52. Multiple guide blocks 42 are vertically arrayed inside the sliding base 41. The support plate 43 is horizontally installed inside the lower layer enclosure 51. The hook guide rod 44 is rotatably installed on the support plate 43. The hook guide rod 44 is slidably installed in the hook sliding groove on the sliding base 41 through the telescopic guide post at the lower end. When the telescopic guide post is aligned with the lowermost guide block 42, the middle layer enclosure 52 is pulled up to the highest position.

[0061] The hook assembly 4 includes a sliding base 41, guide blocks 42, a support plate 43, and a hook guide rod 44. The sliding base 41 is vertically installed on the inner end face of the middle layer enclosure 52. Multiple guide blocks 42 are vertically arrayed within the sliding base 41, guiding the sliding of the hook guide rod 44. The support plate 43 is horizontally installed inside the lower layer enclosure 51, and the hook guide rod 44 is rotatably mounted on the support plate 43. The hook guide rod 44 is slidably installed in the hook sliding groove on the sliding base 41 via a telescopic guide post at its lower end. When the telescopic guide post aligns with the lowest guide block 42, the middle layer enclosure 52 is pulled up to its highest position. At this time, the hook guide rod 44, guided by the sliding base 41, slides along the track of the guide blocks 42 to the end of the sliding base 41. This design allows the hook assembly 4 to stably fix the middle layer enclosure 52 when it is pulled up to its highest position, maintaining its stability. Meanwhile, the design of the sliding base 41 and the guide block 42 also gives the hook assembly 4 good guidance and stability, which can effectively prevent the middle layer enclosure 52 from shifting or shaking during the lifting process.

[0062] The hook assembly 4 includes a sliding base 41, guide blocks 42, a support plate 43, and a hook guide rod 44. The sliding base 41 is vertically mounted on the inner end face of the middle-layer enclosure 52, and contains multiple guide blocks 42 to guide the sliding of the hook guide rod 44. The support plate 43 is horizontally mounted inside the lower-layer enclosure 51, on which the hook guide rod 44 rotates. The hook guide rod 44 is slidably mounted in the hook sliding groove on the sliding base 41 via a telescopic guide post. The main function of the hook assembly 4 is to securely fix the middle-layer enclosure 52 to a designated position, maintaining its stability. This is achieved through the sliding of the hook guide rod 44 on the sliding base 41 and the guidance of the guide blocks 42. The alignment of the telescopic guide post with the positional relationship of the guide blocks 42 ensures that the hook guide rod 44 can smoothly slide to its end when the middle-layer enclosure 52 reaches its highest position, thus firmly locking the middle-layer enclosure 52. This design not only improves the stability of the system, but also effectively prevents the middle layer of the enclosure 52 from shifting or shaking during the lifting process, thereby enabling quick height adjustment and disassembly / removal of the enclosure slide plate 5.

[0063] like Figure 10 As shown, a straight sliding groove 421 is provided on the guide block 42. A hook guide block 422 and an irregularly shaped guide block 423 are installed on one side of the straight sliding groove 421. The upper end of the hook guide block 422 is a support groove 424, which is an inverted V shape. The lower end of the hook guide block 422 divides the straight sliding groove 421 into a guide inclined groove 425. The irregularly shaped guide block 423 is installed above the support groove 424.

[0064] The guide block 42 has a straight sliding groove 421 made of high-strength, wear-resistant alloy steel, which has excellent wear resistance and impact resistance. A hook guide block 422 and a shaped guide block 423 are installed on one side of the straight sliding groove 421. The upper end of the hook guide block 422 has a support groove 424, which is inverted V-shaped. This design can better withstand impact and wear. The lower end of the hook guide block 422 divides the straight sliding groove 421 into a guide inclined groove 425. The slope of the guide inclined groove 425 matches the inverted V-shaped support groove 424 on the hook guide block 422 to ensure that the hook guide rod 44 slides smoothly within the groove path. The inverted V-shaped end face of the support groove 424 is used to support the lower telescopic column of the hook guide rod 44. The hook guide rod 44 hooks onto the guide block 42 through the support groove 424, thereby achieving a fixed height.

[0065] like Figure 10 and Figure 11 As shown, a reversing pad 426 is installed in the straight slide groove 421, and a lifting pad 427 is installed in the guide inclined groove 425. The tails of both the reversing pad 426 and the lifting pad 427 are inclined slopes with increasing height. The head of the reversing pad 426 is an inclined surface that coincides with the lower inclined surface of the hook guide block 422. The head of the lifting pad 427 bends along the guide inclined groove 425 and aligns with the inverted V-shaped inclined surface of the support slot 424. The maximum height of the lifting pad 427 and the reversing pad 426 does not exceed half the depth of the straight slide groove 421.

[0066] The purpose of the internal groove design of the guide block 42 is to optimize the movement of the hook assembly 4. The arrangement of the hook guide block 422 and the irregular guide block 423, as well as the inverted V-shaped structure of the supporting groove 424, ensures that the hook assembly 4 can slide smoothly and cooperate with other components during the lifting process. At the same time, the design of the reversing pad 426 and the lifting pad 427 helps guide the movement direction of the hook guide block 422, ensuring that it stably performs the corresponding actions. In addition, the limitation that the maximum height of the lifting pad 427 and the reversing pad 426 does not exceed half the depth of the straight groove 421 also helps to accurately switch the sliding path of the hook guide rod 44, thereby improving the efficiency and reliability of the entire system.

[0067] In the operation of this invention, the construction personnel first fix the main body 2 of the enclosure to the ground with a bracket. Then, they use a tool to rotate the adjusting rod 311 at the turntable main wheel 31. The rotation of the adjusting rod 311 will drive the internal transmission bevel gear 312 to rotate. The transmission bevel gear 312 transmits power to the adjusting worm gear 314 through the transmission gear set 313. The rotation of the adjusting worm gear 314 drives the adjusting worm wheel 315 to rotate, which in turn drives the turntable main wheel 31 to rotate. The transmission method of the worm wheel and worm gear makes the rotation of the turntable main wheel 31 unidirectional, thereby improving the stability of the pulley assembly 3.

[0068] When the turntable main wheel 31 rotates, it tightens the safety rope 37 wrapped around the pulley assembly 3. The shortening of the safety rope 37 drives the lower pulley 33 to rotate, which in turn pulls up the lower tie rod 34, thereby pulling the middle enclosure 52 to slide upward. At this time, the lower tie rod 34 slides in the meshing groove 54, and then the lower tie rod 34 drives the lifting slide rod 343 to slide upward along the lifting slide groove 342 a short distance, thereby driving the lifting connecting rod 344 to pull the brake top block 345 to slide inward, thereby releasing the jamming state with the brake rack 542. Then the lower tie rod 34 drives the middle enclosure 52 to slide upward. Since the fixed tie rod 32 is installed on the lower enclosure 51 and is in a stationary state, the safety rope 37 on the upper sliding layer will also be pulled up by the fixed tie rod 32. At this time, the upper tie rod 36 at the end of the safety rope 37 will be further pulled up by the safety rope 37, thereby making the upper enclosure 53 rise layer by layer.

[0069] As the barrier slide plate 5 is raised layer by layer, the sliding base 41 on the inner side of the middle barrier 52 will rise accordingly, and the guide block 42 will also rise. Since the hook guide rod 44 on the support plate 43 is fixed in a vertical position, the telescopic column at the lower end of the hook guide rod 44 will slide in the straight slide groove 421, and then enter the guide inclined groove 425 under the joint guidance of the lower end of the hook guide block 422 and the guide pad. The hook guide rod 44 will continue to be raised along the lifting pad, and then the hook guide rod 44 will slide into the support slot 424 at the upper end of the hook guide block 422, thereby hooking and fixing the hook guide rod 44. If unlocking is required, continue to raise it a certain distance. At this time, the hook guide rod 44 will fall into the straight slide groove 421 under the guidance of the lower end of the irregular guide block 423, thereby realizing quick unlocking for disassembly or installation.
