Description

Technical Field

[0001] This utility model relates to the field of building construction hoisting technology, and in particular to a safety hoisting cage. Background Technology

[0002] In the field of construction hoisting, hoisting cages are key equipment used for cargo transfer and material transport in high-altitude operations. Their safety and stability directly affect operational efficiency and the safety of personnel and property.

[0003] Existing hoisting cages generally have the following problems:

[0004] Some hoisting cages use open or simple frame structures and lack complete protective components. During hoisting, the goods are prone to falling due to shaking or tilting, posing a serious safety hazard.

[0005] The lifting lugs are poorly designed, often with single-point or asymmetrical fixation, resulting in uneven stress. This can easily lead to risks such as cage tipping over or lifting lug breakage during lifting, making them unsuitable for transporting heavy or irregular goods.

[0006] The side panels, end panels, and other components of the cage are mostly made of solid wood or simple splicing structures. This not only increases the weight of the cage and the energy consumption of hoisting, but also causes problems such as poor ventilation and obstructed vision, making it difficult to observe the condition of the goods during operation.

[0007] Some openable hoisting cages have rudimentary locking mechanisms with insufficient locking reliability. They are prone to loosening under the vibration of high-altitude hoisting, further exacerbating safety risks. At the same time, the smooth surface of the base makes it easy for goods to slip during transportation, affecting the stability of the load-bearing structure.

[0008] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a safe hoisting cage that has greater industrial value. Utility Model Content

[0009] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a safe hoisting cage.

[0010] The present invention provides a safety hoisting cage, comprising a cage body with one side open, the cage body including a bottom support for supporting goods, and a first side plate, a second side plate and a third side plate fixed vertically upward on the three sides of the bottom support, and two sets of parallel lifting lugs fixed on the outer sides of the first side plate and the second side plate, the upper ends of the lifting lugs extending beyond the upper edges of the first side plate and the second side plate.

[0011] This type of safety hoisting cage has a cage body with an opening on one side. The bottom of the cage body is equipped with a base to stabilize the load. The three sides of the base extend upward and are fixed with a first side plate, a second side plate, and a third side plate, which can effectively prevent the load from slipping off the side during transportation. Two sets of parallel lifting lugs are installed on the outer sides of the first and second side plates. The upper end of the lifting lugs is higher than the upper edge of the side plates, which not only facilitates precise docking with hoisting equipment, but also allows the hoisting force to be evenly distributed, improving the stability and safety of the cage during hoisting.

[0012] Furthermore, a right-angled bottom support is fixed to the bottom of the bottom support on one side of the cage opening, and right-angled side supports are fixed to the outer ends of the first and second side plates. End plates are assembled inside the bottom support and the side supports.

[0013] The bottom of the cage opening is equipped with a right-angled bottom support, and the outer ends of the first and second side plates are equipped with right-angled side supports. These support structures together form a stable installation foundation. The end plate is assembled in the space formed by the bottom support and the side support, which can not only fill the protective gap at the opening of the cage, but also ensure the firmness of its installation through the limiting effect of the support structure, preventing the end plate from loosening and shifting during cargo transfer, and further improving the closed protection effect of the cage.

[0014] Furthermore, cover plates are fixedly installed on the top of the first side plate, the second side plate, and the third side plate.

[0015] The top of the first, second, and third side panels is equipped with a cover plate. The cover plate can seal the open area above the cage, which can prevent the goods from falling from the top during hoisting, prevent external debris from falling into the cage and damaging the goods, and enhance the overall structural stability of the side panels, making the cage more robust and reliable during transportation.

[0016] Furthermore, the first side plate, the second side plate, the third side plate, the end plate, and the cover plate all include an outer frame made of welded profiles, with a mesh welded inside the outer frame.

[0017] The first side plate, second side plate, third side plate, end plate, and cover plate are all welded from profiles to form an outer frame. The inner part of the outer frame is welded with a wire mesh structure. This design not only ensures the structural strength of each component and can withstand the impact of collisions during hoisting, but also achieves good ventilation and visibility through the wire mesh, making it convenient for operators to observe the condition of the goods inside the cage. At the same time, it can also reduce the overall weight, making hoisting operations more convenient and efficient.

[0018] Furthermore, a latch is movably installed on one side above the first or second side plate via a shaft and bushing. The through hole at the end of the latch engages with a locking ring fixed to the end plate. The latch is then secured to the locking ring by a pin or lock after being fitted onto the locking ring.

[0019] A locking buckle is movably installed on one side of the first or second side plate via a shaft and bushing. The through hole at the end of the locking buckle can cooperate with the locking ring fixed on the end plate. When the locking buckle is put into the locking ring, the two can be locked by means of a pin or lock. This structure can quickly achieve a stable connection between the end plate and the side plate, preventing the end plate from accidentally opening and causing the goods to fall during hoisting. It can also be operated conveniently through a flexible movable installation method, taking into account both safety and ease of use.

[0020] Furthermore, the surface of the base is evenly covered with multiple raised ridges.

[0021] The base has multiple raised ridges evenly distributed on its surface. These ridges effectively increase the friction between the goods and the base, preventing the goods from slipping due to shaking or tilting during hoisting and transportation. They also strengthen the base, increasing its load-bearing capacity and making the goods more stable and reliable.

[0022] Furthermore, the lugs are presented as long, ring-shaped structures, with both the upper and lower sides of the lugs fixed to the outer frame of the first or second side plate.

[0023] The lifting lugs adopt a long, ring-shaped design, with both the upper and lower sides firmly fixed to the outer frame of the first or second side plate. This double-fixed structure allows the lifting lugs to evenly bear the tension during lifting, avoiding damage caused by excessive local stress. At the same time, the ring structure is compatible with various lifting connectors, making the connection smoother and further ensuring the stability and safety of the entire lifting process.

[0024] By means of the above-described solution, the present invention has at least the following advantages:

[0025] 1. Safety protection has been comprehensively upgraded. The side plates on three sides of the base, the end plates at the openings, and the top cover form a fully enclosed protective space. Combined with the stable locking structure of the latches and locking rings, the risk of goods slipping from the side or top or the end plates opening accidentally during hoisting is completely eliminated, greatly reducing operational safety hazards. The ridges on the surface of the base increase the friction between the goods and the base, further preventing goods from slipping and ensuring the safety of goods transfer.

[0026] 2. Excellent structural strength and stability: The side plates, end plates, and cover plates adopt a combination structure of welded profile frames and wire mesh, which ensures structural sturdiness and impact resistance while reducing the overall weight of the cage and reducing lifting energy consumption. The lifting lugs adopt a long strip-shaped ring design with double fixation on the upper and lower sides to ensure uniform force distribution during lifting, effectively avoiding problems such as cage tipping over and lifting lug breakage. It is suitable for the transfer needs of heavy and irregular goods and extends the service life of the equipment.

[0027] 3. Significantly improved ease of use: The mesh structure provides the cage with excellent ventilation and visibility, allowing operators to observe the status of goods inside the cage in real time and adjust the operation plan accordingly; the combination of the locking buckle and locking ring allows for flexible operation, enabling quick locking and unlocking of the end plates and improving the efficiency of loading and unloading goods; the ring-shaped lifting lugs are compatible with various lifting connectors, making the connection between the cage and lifting equipment smoother and simplifying the operation process.

[0028] 4. It has stronger adaptability and practicality. The overall structural design takes into account the transportation needs of goods of different sizes and types. Its dual advantages of closed protection and stable load-bearing make it widely applicable to high-altitude operations and cargo transportation scenarios in multiple fields such as construction and logistics, and it has extremely high industrial utilization value.

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0036] See Figure 1First, the goods to be transferred are placed on the bottom tray 2 of the cage 1. The first side plate 3, the second side plate 4, and the third side plate 5 on the three sides of the bottom tray 2 form side protection for the goods, preventing lateral displacement of the goods during placement and initial transfer. Then, the goods are connected to the external lifting equipment through the two sets of parallel lifting lugs 6 on the outer side of the first side plate 3 and the second side plate 4. Because the upper end of the lifting lug 6 extends beyond the upper edge of the first side plate 3 and the second side plate 4, the connecting parts of the lifting equipment can be quickly and accurately engaged. During lifting, the lifting lug 6 evenly transmits the pulling force to the cage 1, driving the cage 1 and the internal goods to rise, fall, and transfer smoothly. The side protection structure can effectively prevent the goods from sliding off the side. The parallel lifting lug 6 ensures balanced lifting force and prevents the cage 1 from tilting or overturning. The height design of the lifting lug 6 facilitates docking with the lifting equipment. The overall structure makes the transfer of goods safer and more efficient, and is suitable for the lifting needs of various operating scenarios.

[0037] See Figure 2 After the goods are placed on the bottom support 2 of the cage 1, the end plate 9 is assembled into the installation space formed by the bottom support 7 at the bottom of the opening side of the bottom support 2 and the side support 8 at the outer end of the first side plate 3 and the second side plate 4. The bottom support 7 and the side support 8 together limit and fix the end plate 9, so that the end plate 9 is firmly attached to the opening of the cage 1. The end plate 9 can fill the protective gap at the opening of the cage 1. With the fixing effect of the bottom support 7 and the side support 8, the end plate 9 is prevented from loosening and shifting during the transfer, forming a complete side protection structure, further preventing the goods from falling from the opening side. At the same time, the support structure also enhances the structural strength of the edge of the cage 1, making the overall protection more reliable.

[0038] After the first side plate 3, the second side plate 4, and the third side plate 5 are installed in place, the cover plate 10 is fixedly installed on top of the three, so that the cover plate 10 and the side plates form a complete three-dimensional protective structure. During operation, the cover plate 10 covers the area above the cage 1. The cover plate 10 can effectively prevent the goods from falling from the top of the cage 1, and at the same time prevent external debris from entering the cage and damaging the goods. It can also reinforce the top of the first side plate 3, the second side plate 4, and the third side plate 5, improve the overall stability of the side plates, and make the cage 1 more stable during hoisting and transportation, further ensuring the safety and integrity of the goods transportation.

[0039] The first side plate 3, the second side plate 4, the third side plate 5, the end plate 9, and the cover plate 10 are all formed by welding profiles to form an outer frame. The mesh is then welded to the inside of the outer frame to complete the assembly. The assembled components together constitute the protective main body of the cage 1. During operation, the components work together to provide protection. The profile outer frame can ensure the structural strength of the first side plate 3, the second side plate 4, the third side plate 5, the end plate 9, and the cover plate 10, and resist the collision and impact during the hoisting process. The mesh structure can achieve good ventilation and visibility, making it convenient for operators to observe the status of the goods inside the cage. At the same time, it greatly reduces the weight of each component and the overall weight of the cage 1, making the hoisting operation more convenient and efficient, and taking into account both structural stability and practicality.

[0040] See Figure 3 The locking buckle 11 is movably installed on the upper side of the first side plate 3 or the second side plate 4 via a shaft and bushing. After the end plate 9 is assembled in place, the locking buckle 11 is rotated so that the through hole at its actual end fits into the locking ring 12 fixed on the end plate 9. Then, the locking buckle 11 and the locking ring 12 are locked and fixed with a pin or lock to complete the locking operation between the end plate 9 and the side plate. The precise cooperation between the locking buckle 11 and the locking ring 12 can achieve a stable lock on the end plate 9, avoiding the end plate 9 from being accidentally opened during hoisting and transportation, and completely eliminating the risk of goods falling from the open side. The movable installation design of the shaft and bushing makes the locking buckle 11 flexible to operate, and the locking and unlocking process is convenient and efficient, taking into account both operational safety and the convenience of loading and unloading goods.

[0041] When goods are placed on the base tray 2 of the cage 1, the evenly distributed protrusions 13 on the surface of the base tray 2 come into direct contact with the bottom of the goods. They play a continuous role throughout the entire process of goods placement, hoisting and transfer. The protrusions 13 can effectively increase the friction between the goods and the base tray 2, preventing the goods from slipping due to shaking or tilting during hoisting. At the same time, the protrusions 13 strengthen the structure of the base tray 2, improve the load-bearing capacity of the base tray 2, and keep the goods stable on the base tray 2, further ensuring the safety and integrity of the goods during the transfer process.

[0042] The lifting lug 6 adopts a long, ring-shaped structure, with both its upper and lower sides firmly fixed to the outer frame of the first side plate 3 or the second side plate 4. During the lifting operation, the connecting parts of the external lifting equipment precisely align with the ring-shaped lifting lug 6, and the lifting lug 6 transmits the lifting force to the outer frame of the first side plate 3 or the second side plate 4. The long, ring-shaped structure is compatible with various lifting connecting parts, making the connection smoother. The fixing method on the upper and lower sides can distribute the lifting force to the two outer frames of the first side plate 3 or the second side plate 4, avoiding localized force concentration that could lead to damage, significantly improving the stability of the lifting operation, while ensuring uniform force transmission, effectively preventing the cage 1 from tilting or overturning, and further enhancing the safety and reliability of the entire lifting process.
