Tower crane comprehensive intelligent monitoring device

Abstract

The invention discloses a tower crane comprehensive intelligent monitoring device of building tower crane hoisting work. A tower crane safety hoisting operation contact device, an air speed sensor, a charging station and an operation room wireless router are connected with an operation room monitoring device through signal cables. A tackle wireless router, a tackle monitoring device battery pack, a monitoring camera, a speed reducer absolute shaft encoder and a hoisting hook weight measuring sensor are connected with a tackle monitoring device through signal cables. A command signal emitter is connected with the tackle monitoring device in a wireless communication mode. By monitoring air speed, goods weight, the depth of a hoisting hook, hoisting speed and a goods video image during work of a tower crane, digital monitoring of tower crane work is achieved, and once a parameter upper limit is exceeded, a control circuit is switched off and work stops. By means of hoisting hook depth monitoring, automatic focusing of the monitoring camera is achieved, and definition of hoisted goods with in the whole visual range is guaranteed. By means of the device, intrinsic safety work of the tower crane in real sense is achieved.

Description

technical field [0001] The patent of the present invention relates to construction operations, especially the hoisting operation of construction tower cranes. Background technique [0002] Tower cranes are referred to as tower cranes for short, also known as tower cranes, which originated in Western Europe. According to records, the first patent related to tower cranes for construction was issued in 1900. In 1905, a crane equipped with a jib with a fixed tower body appeared. In 1923, a prototype of a modern tower crane was produced. In the same year, the first relatively complete modern tower crane appeared. In 1930, Germany had started mass production of tower cranes and used them in construction. In 1941, the German industrial standard DIN8770 concerning tower cranes was announced. The standard stipulates that the product (tm) of the hoisting load (t) and the amplitude (m) is used to express the lifting capacity of the tower crane in terms of gravity. my country's towe...

Problems solved by technology

[0005] However, in actual operation, it is difficult to ensure that operators strictly follow the "ten" to perform hoisting operations; It is difficult to visually distinguish materials, which seriously affects the operation efficiency, and there are major safety hazards
