Monitoring tray for tower crane

Abstract

Provided is a monitoring tray for a tower crane. A tray used in cooperation with the tower crane can hardly carry out monitoring in the whole process, and consequently a dead zone is generated in thelifting process, and the rising and falling position is not accurate or safe. The monitoring tray comprises a tray body and a monitoring assembly. The monitoring assembly comprises a plurality of monitoring monomers, the monitoring monomers are arranged at the bottom of the tray body, and each monitoring monomer comprises a shell, a first shielding assembly, a camera, a controller and multiple photosensitive sensors. Each first shielding assembly comprises a cover plate, a gear rack, a gear and a motor. The cover plates are driven by the gear racks to do reciprocating motion in the length direction of the shells, the cameras are arranged in the shells, the camera shooting ends of the cameras faces openings, the multiple photosensitive sensors are all arranged on the outer walls of the shells and are arranged around the openings, and each photosensitive sensor is connected with the corresponding motor through the corresponding controller. The first shielding assemblies can be replaced with second shielding assemblies. The monitoring tray is used for the hoisting process.

Description

Technical field: [0001] The invention relates to a pallet, in particular to a monitoring pallet used for a tower crane. Background technique: [0002] Tower crane is the most commonly used lifting equipment on construction sites. It is used to lift construction materials such as steel bars, wooden corrugations, concrete, and steel pipes. There is a lack of matching auxiliary tools in the lifting process, even if a few have tools. , is also a simple-structured material-holding tool, which can only be used to fix raw materials and has no special function and use value. During the lifting and landing process of raw materials, it is easy to appear uncontrollable links. Specifically, the falling distance of materials is a blind area. Due to the operation It is difficult for personnel to quantitatively detect the falling distance and observe the falling position. They can only operate based on experience. Insufficient experience is prone to lead to inconsistent quality of whereabo...

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is used to lift construction materials such as steel bars, wooden corrugations, concrete, and steel pipes. There is a lack of matching auxiliary tools in the lifting process, even if a few have tools. , is also a simple-structured material-holding tool, which can only be used to fix raw materials and has no special function and use value. During the lifting and landing process of raw materials, it is easy to appear uncontrollable links. Specifically, the falling distance of materials is a blind area. Due to the operation It is difficult for the personnel to quantitatively detect the falling distance and observe the falling position. They can only operate based on experience. Insufficient experience is likely to lead to inconsistent quality of falling scheduling, and even lead to some safety accidents, which directly affect construction efficiency and quality.
