Description

Technical Field

[0001] This utility model relates to safety protection devices, and in particular to a safety protection enclosure for tower cranes. Background Technology

[0002] As a core heavy equipment in construction, the support and surrounding area of ​​tower cranes are critical parts for construction safety. Currently, most existing tower crane supports lack dedicated protective structures or only use simple fences for preliminary isolation, which has limited protective effect.

[0003] From a practical construction perspective, the lack of effective external shielding around tower cranes makes it easy for non-operating personnel to attempt illegal climbing out of curiosity or for other reasons. This could not only lead to falls, collisions, and other safety accidents, but also disrupt the normal operation of the tower crane, causing equipment malfunctions or construction stoppages. Furthermore, the escalator attached to the tower crane is the only access point for operators to ascend and descend. The existing structure lacks specific protective design at the connection between the escalator and the support, allowing unauthorized personnel to directly climb onto the tower crane's working platform. This not only poses a significant personal safety risk but also increases the risk of equipment misoperation and component damage due to unauthorized personnel entering the work area.

[0004] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a tower crane safety protection enclosure that has greater industrial application value. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a safety protection enclosure for tower cranes.

[0006] This utility model discloses a safety protection enclosure for tower cranes, including tower crane supports, through mounting rods between the tower crane supports, a surrounding plate fixed on the mounting rods to encircle the entire tower crane support, an inner plate fixed on the mounting rods inside the tower crane supports, and a through groove for a ladder to pass through between the inner plate and one side wall of the tower crane support.

[0007] This type of tower crane safety enclosure includes tower crane supports, with mounting rods running through the supports. A perimeter panel is fixed to the mounting rods, forming an external protection around the entire tower crane support to prevent unauthorized personnel from climbing the tower crane from the outside. An inner panel is also fixed to the portion of the mounting rod inside the tower crane support. A through groove is provided between the inner panel and one side wall of the tower crane support, allowing an escalator to pass smoothly. Simultaneously, the inner panel provides protection around the escalator, preventing unauthorized entry by personnel.

[0008] Furthermore, vertical connecting rods are welded to the outside of the enclosure, and the outer surface of the connecting rods is covered with skin.

[0009] Vertical connecting rods are fixed to the outside of the enclosure by welding. The connecting rods provide support and reinforcement, and the skin covering the outer surface of the enclosure further seals off the protective space outside the enclosure, reduces the points of leverage for climbing, and enhances the overall protective sealing of the enclosure, preventing unauthorized personnel from attempting to climb from the outside of the enclosure.

[0010] Furthermore, the side panels and inner panels are made of wire mesh.

[0011] Both the outer and inner panels are made of wire mesh. The wire mesh structure ensures the structural strength of the enclosure and effectively resists external impacts, while also providing good permeability, allowing construction workers to easily observe the tower crane supports and the surrounding area of ​​the ladder. At the same time, it does not affect the ventilation of the protected area, thus achieving both safety protection and ease of use.

[0012] Furthermore, an openable and closable partition is installed on the inner panel near the escalator via hinges, allowing tower crane operators to pass through when the partition is open.

[0013] The inner panel is fitted with a partition that can be flexibly opened and closed on the side closest to the escalator via hinges. When the partition is closed, it can seal the gap between the inner panel and the escalator, preventing unauthorized personnel from passing through. When opened, it provides a safe and convenient passage for tower crane operators, taking into account both protection and operational convenience.

[0014] Furthermore, a locking ring is fixed between the side of the partition away from the hinge and the inner panel, and the through hole of the locking ring is used for locking the latch.

[0015] A locking ring is fixedly installed between the side of the partition away from the hinge and the inner panel. The through hole of the locking ring can be used with a locking device to firmly lock the partition in the closed state, preventing unauthorized personnel from opening the partition and illegally entering the escalator area, thus further enhancing the safety protection effect of the enclosure.

[0016] Furthermore, there is a gap between the outer panel and the inner panel, through which the tower crane support passes, and the width of the gap is between 10-20cm.

[0017] A gap is reserved between the enclosure and the inner panel to allow the tower crane support to pass through smoothly. This gap can accommodate the installation requirements of the tower crane support, ensuring that the enclosure and the support fit precisely and do not affect the normal use of the equipment. At the same time, the reasonable gap space can avoid collision and friction between the enclosure and the support, ensuring the stability of the protective structure and the safety of equipment operation. It can also effectively prevent personnel from passing through, further eliminating the safety hazard of illegal climbing.

[0018] Furthermore, the enclosure extends 50-70cm outward from the tower crane support, and the connecting rod is 60-80cm high.

[0019] The enclosure extends a certain distance outward from the tower crane support. This extension design expands the protection range, forming a wider safety barrier that effectively prevents personnel from climbing near the outer perimeter of the tower crane support. The connecting rod is set to a certain height, which, together with the skin on its outer surface, further increases the vertical protection height of the enclosure, reduces the risk of climbing over the top of the enclosure, and enhances the overall tightness of the protection.

[0020] By means of the above-described solution, the present invention has at least the following advantages:

[0021] 1. Comprehensive protection: The surrounding panels form the first line of defense around the tower crane support, and the inner panels provide targeted protection around the escalator. This double protection from the outside and key passages prevents unauthorized personnel from climbing, completely solving the safety hazards caused by insufficient traditional protection and significantly reducing the risk of accidents such as personnel falling and equipment misoperation.

[0022] 2. High structural stability: The installation rods penetrate the tower crane supports to achieve a firm fixation of the enclosure. The welding of the connecting rods and the enclosure panels further enhances the support effect. The enclosure panels and inner panels made of mesh material take into account both structural strength and impact resistance, ensuring that the enclosure is stable and reliable in the construction environment and is not easily deformed or damaged.

[0023] 3. Excellent practicality and convenience: The mesh structure has good permeability and ventilation, making it convenient for construction personnel to observe the protected area in real time; the openable and closable partitions, combined with the locking ring design, not only ensure the operator's convenient passage, but also restrict unauthorized personnel from entering through the locks, achieving a balance between protection and use.

[0024] 4. Combining adaptability and safety: The gap between the enclosure and the inner panel is precisely adapted to the tower crane support installation requirements, avoiding structural interference while preventing personnel from passing through. The outward extension of the enclosure and the height design of the connecting rod expand the protection range and reduce the risk of climbing over. The overall structure can be adapted to tower cranes in different scenarios without complex modifications, making it highly valuable for industrial applications.

[0032] The specific embodiments of this utility model will be described in further 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 its scope.

[0033] See Figure 1 When the safety protection enclosure for this tower crane is in operation, the overall structure is first stably assembled by the mounting rod 2 that penetrates the tower crane support 1. The enclosure plate 3 fixed on the mounting rod 2 surrounds the entire tower crane support 1 to form a closed protection, preventing unauthorized personnel from approaching or climbing the tower crane from the outside. At the same time, the inner plate 4 fixed on the mounting rod 2 inside the tower crane support 1 forms a through groove with the side wall of the tower crane support 1, allowing the escalator 7 to pass through normally. The inner plate 4 can protect the area around the escalator 7, preventing personnel from illegally entering the tower crane operation area from the escalator 7. The structure is simple and reliable to assemble. The double protection of the enclosure plate 3 and the inner plate 4 achieves comprehensive safety isolation between the tower crane perimeter and key passages. Without affecting the normal operation of the tower crane and the operator's passage through the escalator 7, it effectively eliminates the safety hazards caused by illegal climbing, balancing the protective effect and the convenience of use.

[0034] The vertically upward connecting rods 5, which are welded and fixed to the outside of the enclosure panel 3, provide vertical support for the enclosure. At the same time, the skin 6 covering the outer surface of the connecting rods 5 can seal the gaps on the outside of the enclosure panel 3 and reduce the points of force for climbing, further improving the external protective structure of the enclosure panel 3. The connecting rods 5 not only enhance the structural stability of the enclosure panel 3 and prevent the enclosure panel 3 from being deformed by external forces, but also improve the protective sealing of the enclosure in conjunction with the skin 6. It effectively prevents unauthorized personnel from climbing from the outside of the enclosure panel 3 from both vertical and horizontal directions. It enhances the safety protection effect without affecting the overall assembly of the enclosure, and the structure is simple, durable and requires no additional maintenance.

[0035] Both the enclosure panel 3 and the inner panel 4 are made of mesh panels. During operation, the enclosure panel 3 forms a stable protective barrier around the tower crane support 1 based on the structural strength of the mesh panels. The inner panel 4, made of mesh panels, ensures the reliability of the protection around the escalator 7. At the same time, the permeability of the mesh panels allows construction personnel to clearly observe the inside of the enclosure and the surrounding area of ​​the tower crane support 1 without affecting the real-time monitoring of the equipment's operating status. The mesh panel material not only gives the enclosure panel 3 and the inner panel 4 sufficient impact resistance to ensure that the protective structure is not easily damaged, but also has good ventilation to prevent the formation of a closed and stuffy environment inside the enclosure. The permeable design also facilitates the timely detection of safety hazards. While enhancing the protective effect, it also takes into account the convenience and practicality of use. The structural design is more in line with the needs of the construction scenario.

[0036] See Figure 3 and Figure 4 On the inner panel 4, near the escalator 7, the partition 9 is flexibly installed via hinge 8. When the partition 9 is closed, it can seal the gap between the inner panel 4 and the escalator 7, preventing unauthorized personnel from entering. When the tower crane operator needs to pass through, the partition 9 can be opened to go up or down the tower crane from the escalator 7. The hinge 8 makes the opening and closing of the partition 9 convenient and smooth. The closed state of the partition 9 enhances the protective effect of the inner panel 4 on the escalator 7 area, while also meeting the normal passage needs of the operator, achieving an effective balance between protective safety and ease of use. The structural design fits the actual construction scenario.

[0037] The locking ring 10 fixed between the side of the partition 9 away from the hinge 8 and the inner plate 4 can be used with a locking device. When the partition 9 is closed, the locking device passes through the through hole of the locking ring 10 to securely lock the partition 9 and the inner plate 4, preventing unauthorized personnel from opening the partition 9 and illegally entering the escalator 7 area. The design of the locking ring 10 further enhances the safety of the protection, forming a double protection with the partition 9. It does not affect the normal opening and passage of the tower crane operator, and can effectively eliminate the safety hazards caused by illegal entry. The structure is simple and the locking is reliable, which is suitable for the safety management needs of the construction scene.

[0038] The gap between the enclosure panel 3 and the inner panel 4 allows the tower crane support 1 to pass through smoothly, ensuring that the entire enclosure can be precisely fitted to the tower crane support 1 for assembly. At the same time, this gap can prevent personnel from passing through, avoiding illegal climbing, and does not affect the normal operation of the tower crane support 1. The gap design not only achieves the compatible installation of the enclosure and the tower crane support 1, avoiding structural interference, but also further improves the protection system. Combined with the double protection of the enclosure panel 3 and the inner panel 4, it enhances the safety effect. The structural design is simple and reasonable, and can be adapted for use without additional modifications, taking into account both installation convenience and protection reliability.

[0039] The enclosure panel 3 extends outwards from the tower crane support 1 to form a wide safety isolation zone, expanding the protection range around the tower crane and preventing unauthorized personnel from approaching the tower crane support 1 and attempting to climb it. At the same time, the connecting rod 5 on the outside of the enclosure panel 3 is set vertically upwards, further increasing the vertical protection height of the enclosure. Together with the skin 6, it reduces the possibility of climbing over from the top of the enclosure panel 3. The extension design of the enclosure panel 3 and the height setting of the connecting rod 5 form a three-dimensional protection space, which greatly reduces the risk of illegal climbing. Moreover, the structural layout is reasonable and does not affect the normal working space of the construction site. While strengthening the comprehensiveness of protection, it also takes into account the flexibility of use and adapts to the safety needs of various construction scenarios.
