Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety monitoring equipment technology, and in particular to a safety monitoring device for tower cranes. Background Technology
[0002] At construction sites, tower cranes are often overloaded due to tight construction schedules or operator errors. Overloading can cause excessive stress on the crane's metal structure, leading to structural deformation or even breakage. It can also affect the crane's braking system and operational stability, easily causing serious safety accidents such as falling objects or the entire machine tipping over. Therefore, it is necessary to design a tower crane safety monitoring device.
[0003] Existing monitoring equipment often lacks universality in its installation structure, making it difficult to adapt to various types of tower cranes. Customized installation structures or crane modifications are required, limiting the widespread application of security monitoring equipment, increasing equipment procurement and installation costs, and adding to installation difficulty. A more convenient installation structure improves construction efficiency and reduces the impact of prolonged installation time on construction progress. Furthermore, the fixed initial installation angle of some equipment's image displays results in a limited adjustable range, making it difficult for operators to obtain images from certain key perspectives. This limits the effectiveness of image monitoring, affects operators' ability to continuously and stably observe the images, and reduces the reliability of image monitoring.
[0004] A tower crane safety monitoring device disclosed in announcement number CN220485177U is installed in conjunction with a tower crane. A scene measurement mechanism is installed at the top of the tower, while a computer host and electronic display screen are installed in the operator's cab. The scene measurement mechanism includes: a first mounting frame fixed to the top of the tower; a second mounting frame hinged to the first mounting frame in a relatively rotatable manner in the middle; an ultrasonic rangefinder and a wide-angle camera fixedly installed on the front end of the second mounting frame; and an electric telescopic rod hinged at one end to the rear end of the second mounting frame and the other end to the first mounting frame. The ultrasonic rangefinder and the wide-angle camera are installed parallel and close to each other, both facing the boom side of the tower crane. This utility model facilitates stable and intuitive operation of the tower crane by workers, enabling goods to effectively avoid obstructions, and allowing back-end personnel to promptly understand the operating status of the tower crane.
[0005] While the aforementioned patent achieves the goal of having both the ultrasonic rangefinder and the wide-angle camera facing the boom of the tower crane, facilitating stable and intuitive operation of the tower crane by the staff and enabling the goods to effectively avoid obstructions, and allowing the back-end personnel to promptly understand the operating status of the tower crane, the device lacks the function of installing a monitoring controller and adjusting the angle of the image display, making it impossible for the operator inside the cab to more intuitively and conveniently observe the situation and images outside the tower crane. Utility Model Content
[0006] (a) Technical problems to be solved

[0008] (II) Technical Solution
[0009] To achieve the above objectives, this utility model provides the following technical solution: a tower crane safety monitoring device, comprising a monitoring controller, with hydraulic clamps snapped onto the upper and lower sides of the monitoring controller, an installation mechanism fixedly connected to the bottom of the hydraulic clamps, a right-angle fixing plate A threadedly connected to the right side of the monitoring controller, an adjustment mechanism rotatably connected to the inner side of the right-angle fixing plate A, the installation mechanism comprising a clamping telescopic rod fixedly connected to the bottom of the hydraulic clamp, a connecting rod fixedly connected to the bottom of the clamping telescopic rod, a slider fixedly connected to the back of the connecting rod, an installation bracket slidably connected to the outside of the slider, and an adjustment mechanism comprising a rotating rod rotatably connected to the inner side of the right-angle fixing plate A, a connecting block A rotatably connected to the outside of the rotating rod, an adjusting hydraulic rod fixedly connected to the top surface of the connecting block A, and a connecting block B fixedly connected to the top of the adjusting hydraulic rod.
[0010] As a further embodiment of this utility model, a rotating frame is rotatably connected inside the connecting block, and right-angle fixing plates B are rotatably connected to both sides of the rotating frame. An image display is threadedly connected to the back of the right-angle fixing plate B. The image display facilitates observation of the external situation and the image of the tower crane.
[0011] As a further embodiment of this utility model, the right-angle fixing plate B has a fixing hole inside, and a fixing bolt passes through the fixing hole. The fixing bolt serves to fix the part to the side of the image display.
[0012] As a further embodiment of this utility model, the mounting bracket is provided with a sliding groove inside, and the inside of the sliding groove is slidably connected to the outside of the slider. The slider is designed to adjust the position of the mounting plate for easy installation.
[0013] As a further embodiment of this utility model, the mounting bracket is externally slidably connected to a buckle plate, and the back of the buckle plate is fixedly connected to a mounting plate. The mounting plate facilitates installation in different positions.
[0014] As a further embodiment of this utility model, the surface of the mounting plate is provided with mounting holes, and mounting bolts pass through the interior of the mounting holes. The installation of mounting bolts increases the installation firmness.
[0015] As a further embodiment of this utility model, a limiting hole is provided on the upper surface of the clamping telescopic rod, and a limiting bolt is connected to the internal thread of the limiting hole. The limiting bolt serves to adjust the clamping position according to the size of the monitoring controller.
[0016] (III) Beneficial Effects
[0017] This utility model provides a safety monitoring device for tower cranes, which has the following beneficial effects:
[0018] 1. This tower crane safety monitoring equipment, through its installation mechanism, allows for easy setup. First, the slider is slid to adjust the position of the clamping telescopic rod according to the size of the monitoring controller. After adjustment, the hydraulic clamp automatically retracts to hold the controller on both sides, securing it in place. Then, the mounting plate is adjusted by sliding the buckle plate according to the required installation location. Finally, the mounting bolts are tightened. This system facilitates installation and adaptability to different sizes and models of monitoring controllers, avoiding the need for customized installation structures or crane modifications that restrict the widespread application of safety monitoring equipment, increase procurement and installation costs, and complicate installation.
[0019] 2. This tower crane safety monitoring equipment, through the setting of the adjustment mechanism, allows the hydraulic rod to be extended or retracted when the device is to be used, causing the connecting blocks A and B on both sides to rotate. Since a rotating frame is installed at the top of the connecting block B, and the rotating frame is connected to a right-angle fixing plate B, the right-angle fixing plate B then pulls the image display on its back, allowing the image display to automatically adjust its angle. This facilitates angle adjustment and makes it easier for operators to observe the external situation and images. It avoids the problem that a small adjustment range makes it difficult for operators to obtain images from certain key perspectives, which would limit the effectiveness of image monitoring, affect the operator's continuous and stable observation of the image, and reduce the reliability of image monitoring.
