Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0013] The invention provides a speed controller of a hoisting power shaft of a tower crane capable of effectively controlling the speed.

[0014] like figure 1 , figure 2 As shown, a tower crane hoisting power shaft speed controller 1 includes a controller body 2, and a power shaft interface 31 and a power shaft output port 32 are arranged at both ends of the controller body 2. A resistance device 4 is arranged in the center of the device body 2, and a power adjustment knob 5 is arranged on the side of the resistance device 4.

[0015] like figure 1 , figure 2 As shown, the controller body 2 is made of high-strength hard steel.

Abstract

The invention discloses a speed controller for a tower crane lifting power shaft. The speed controller for the tower crane lifting power shaft comprises a controller body, wherein a power shaft connector and a power shaft output port are arranged in the two ends of the controller body, a resistance device is arranged at the centre of the controller body, and a power adjustment knob is arranged on the side surface of the resistance device; and the controller body is made from high-strength hard steel, and the resistance device is of a square structure and rigidly connected to the controller body. According to the speed controller for the tower crane lifting power shaft, which is disclosed by the invention, because the resistance of the resistance device is controlled by virtue of the power adjustment knob, rotation of the power shaft which rapidly rotates can be prevented, and then a lifting speed in a safety range during running of a tower crane is ensured, thus construction safety is ensured; and moreover, because the controller body is made from the high-strength hard steel, and the resistance device is of the square structure and rigidly connected to the controller body, safety and stability during running of the device can be ensured.

Description

technical field [0001] The invention relates to a speed controller, more precisely, a speed controller of a tower crane hoisting power shaft. Background technique [0002] The hoisting speed of existing tower cranes is mostly controlled by humans, and it is difficult to ensure that the hoisting speed is strictly controlled within a safe range. When working in a long-term working environment, it is difficult to ensure the safety of hoisting due to fatigue of personnel. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a speed controller of the hoisting power shaft of the tower crane that can effectively control the speed. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A tower crane hoisting power shaft speed controller, comprising a controller body, a power shaft interface and a power shaft output port are arranged a...
