Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, specifically to a built-in support platform for a tower crane. Background Technology

[0002] In the construction industry, tower cranes are widely used as key vertical transportation equipment in various engineering projects. During the operation of tower cranes, their stability and safety are of paramount importance. Tower cranes often lack a dedicated built-in support platform, which makes it difficult for them to ensure stable operation under some complex working conditions. In windy weather or when lifting heavy loads, the cranes are prone to swaying, affecting operational accuracy and potentially causing safety accidents.

[0003] Furthermore, as construction projects develop towards higher-rise and larger scale, higher requirements are placed on the load-bearing capacity and stability of tower cranes. Traditional support methods are no longer able to meet the growing construction demands, and there is an urgent need for a more efficient, reliable support solution that can adapt to complex construction environments. At the same time, the protection and communication of the support platform are relatively difficult. Therefore, we propose an internal support platform for tower cranes. Utility Model Content

[0004] The purpose of this invention is to provide a built-in support platform for a tower crane to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a built-in support platform for a tower crane, comprising a support column, a rotating platform, a stepped platform, a platform support base, a load-bearing cage, an adjustable mounting frame, and an inclined reinforcement frame. The rotating platform is mounted on the top of the support column, and a guardrail is mounted on the rotating platform. The stepped platform is also mounted on the top of the rotating platform. When the built-in support platform of the tower crane is in operation, the support column provides stable support, fixing the entire platform structure at a suitable height. The rotating platform can rotate about the top of the support column as an axis, allowing the components mounted on it to change their operating direction. When hoisting materials to different locations, the rotating platform rotates, causing the stepped platform and related equipment to turn in the target direction. Guardrails are installed on the rotating platform to protect personnel working on it, preventing accidental falls due to platform rotation or other factors. A platform support base is installed at the top of the stepped platform, and a load-bearing cage is installed on top of the support base. The load-bearing cage provides a safe working space for workers, and its robust structure effectively prevents injury from falling materials or accidental impacts. The platform support base, as a key component connecting the stepped platform and the load-bearing cage, ensures the stability of the entire structure. In addition to its load-bearing capacity, the load-bearing cage is equipped with safety doors and locks, ensuring that workers can only enter or leave the work area when safety is guaranteed, further enhancing operational safety. One end of the load-bearing cage is equipped with an adjustable mounting bracket, and the other end with a connecting mounting base. The adjustable mounting bracket allows for fine-tuning of the angle or position of one end of the cage according to actual operational needs. This flexibility ensures that workers can obtain the optimal working view and operational convenience in different work scenarios. The connecting mounting base is securely connected to the other end of the load-bearing cage, serving not only as a fixing function but also as a connection point for other equipment or... The interface of the structural connection enhances the scalability and applicability of the entire platform. One side of the connecting mounting base is connected to the bottom of the inclined reinforcement frame, and the top of the inclined reinforcement frame is fixedly connected to the top of the adjusting mounting frame. The other side of the connecting mounting base is equipped with a rotating component via a rotating shaft. The setting of the inclined reinforcement frame further enhances the stability of the entire structure. Like a bridge, it tightly connects the connecting mounting base and the adjusting mounting frame, effectively resisting the impact and vibration that may be brought by external forces, ensuring the smooth operation of the work platform. The inclination of the inclined reinforcement frame optimizes the overall stress structure, making the entire platform more stable and reliable when bearing heavy loads.

[0006] Preferably, ladders are fixed to the side walls of the support columns, platform support bases, and load-bearing cages. A communication box is installed at the bottom of the rotating platform, containing a wireless communication module and a control module. The wireless communication module can transmit data and images from the work site to a remote monitoring center in real time, facilitating real-time monitoring and guidance of the work process by management personnel, greatly improving the safety and efficiency of the operation. The control module is responsible for receiving instructions from the remote monitoring center and precisely controlling parameters such as the rotation angle and working height of the rotating platform, ensuring the accuracy and stability of the operation. The ladders facilitate safe and convenient access for workers to climb up and down the work platform, providing a comfortable grip and stable support, ensuring worker safety even in harsh working environments. The use of ladders, communication boxes, and other components not only enhances the practicality and safety of the entire support platform but also reflects humanistic care for workers and a pursuit of technological innovation.

[0007] Preferably, the stepped platform is provided with a stepped frustum, the top of which is fitted with a pressure plate. A ventilation slot is provided between the stepped frustum and the pressure plate. The outer perimeter of the stepped frustum and the pressure plate is secured with clips, and a rotating door is installed on the top of the clips via hinges. The stepped frustum not only provides a stable support surface, but also enhances the load-bearing capacity of the platform through its unique structure. The ventilation slots effectively improve the ventilation conditions of the platform, preventing excessively high internal temperatures caused by prolonged operation, thus providing a more comfortable working environment for the workers. The installation of the pressure plate further stabilizes the structure of the stepped frustum, and the choice of its material ensures the durability and safety of the platform.

[0008] Preferably, the support cage is equipped with a protective baffle. From left to right, a primary tension frame, a tension adjustment frame, and a secondary tension frame are installed on the upper surface of the support cage mounting base. The protective baffle effectively blocks any splashes that may be generated during operation, protecting the safety of the workers and providing them with a more private working space, reducing external interference. The sequential installation of the primary tension frame, tension adjustment frame, and secondary tension frame not only ensures the stability and robustness of the support cage structure but also allows for flexible adjustment of the overall tension of the hanger through the adjustment function of the tension adjustment frame, adapting to different working environments and requirements.

[0009] Preferably, the adjusting mounting frame is equipped with an H-shaped fixing frame, and a primary guide wheel is installed on the top of the H-shaped fixing frame. Maintenance railings are installed around the top of the H-shaped fixing frame and the inclined bracket. The H-shaped fixing frame not only enhances the structural stability of the adjusting mounting frame, but also provides a stable installation foundation for the primary guide wheel. The primary guide wheel effectively guides the routing of various cables in the tower crane, avoiding cable clutter and improving the safety and cleanliness of the work site. The maintenance railings provide a safe and reliable handrail for workers to maintain or repair the adjusting mounting frame and surrounding equipment, further ensuring the safety of workers.

[0010] Preferably, the inclined reinforcement frame is equipped with an inclined tie frame, secondary guide wheels are installed between the top tie rods of the inclined tie frame, and three sets of tension guide wheels are installed between the tie rods of the inclined tie frame. An inclined reinforcement rod is fixed on the inclined tie frame. The setting of the secondary guide wheels effectively guides the direction of the transmission components such as wire ropes or chains in the tower crane, ensuring their stability and accuracy during operation. The three sets of tension guide wheels can flexibly control the tension of the transmission components by adjusting their tension to adapt to the operational needs under different working conditions. The installation of the inclined reinforcement rod further enhances the structural strength of the inclined tie frame, improves the overall load-bearing capacity and stability, thereby ensuring the safe and reliable operation of the tower crane's built-in support platform.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The inclined reinforcement frame of this utility model further enhances the stability of the entire structure. Like a bridge, it tightly connects the connecting mounting base and the adjusting mounting frame, effectively resisting the impact and vibration that may be caused by external forces, ensuring the smooth operation of the work platform. The inclination of the inclined reinforcement frame optimizes the overall stress structure, making the entire platform more stable and reliable when bearing heavy loads.

[0013] When the built-in support platform of this tower crane is in operation, the support column provides stable support, fixing the entire platform structure at a suitable height. The rotating platform can rotate around the top of the support column as an axis, which allows the components installed on it to change the working direction. When materials need to be hoisted to different locations, the rotating platform rotates, driving the stepped platform and related equipment to turn towards the target direction. Guardrails are installed on the rotating platform to provide protection for personnel working on the platform, preventing accidental falls due to the rotation of the rotating platform or other situations.
