Abstract

The invention discloses a speed control device for a building tower crane rotating mechanism. The device comprises a main body shell. The device utilizes the circulating flow of liquid to control therotational speed of a rotating part through control over the maximum flow amount of the liquid during flow, and thus the occurrence of accidents such as rapid falling due to too quick rotation of therotational part is prevented; the device has strong control capability, and other control devices are not required for assistance; also, the device has a threaded structure moving screwing type liquidflow control mechanism, and the maximum flow quantity of the flowing liquid can be controlled, so that a series of control effects are achieved; in addition, the device has a spiral spring abutting type maximum liquid flow control mechanism, and the internal maximum liquid pressure can be controlled, so that the damage phenomenon of a driving motor, caused by too large resistance, is prevented; and in addition, the device has a rotary shaft installation type fixing connection mechanism, the connection between shaft bodies of different sizes can be realized, and thus the connection range is expanded.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a speed control device for a rotating mechanism of a construction tower crane. Background technique [0002] At present, in construction sites, construction tower cranes are indispensable. In tower cranes, the drive motor and hoisting wheel are directly fixedly connected. Therefore, once the control is unstable or improperly operated during work, it is likely to cause Accidents caused by lifting heavy objects and falling down have great potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a speed control device for the rotating mechanism of a construction tower crane, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a speed control device for the rotating mechani...
