Description
Technical Field
The utility model relates to a hoisting equipment technical field specifically is a steady device that plays to rise that is used for tower machine to play to rise.
Background
The tower crane is a tower crane, also called tower crane, which refers to a multi-action hoisting machine for vertically lifting and horizontally carrying heavy objects in a certain range, and has very wide application. In the process that a heavy object of a tower crane rises from the ground, if a driver rises at a high speed, a crane boom of the tower crane suddenly receives a quick loading force at the moment of being away from the ground, the crane boom jumps up and down and drives the heavy object to swing, a steel wire rope of a lifting mechanism is suddenly and quickly tightened from a loose state, and the steel wire rope also receives a quick pulling force, so that the operation process causes great impact on an integral steel mechanism and the steel wire rope of the tower crane, the steel wire rope is possibly damaged or even broken, and property loss and safety accidents are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a steady device that plays to rise for tower machine plays to when the tower machine that proposes in solving above-mentioned background art lifts heavy thing liftoff in the twinkling of an eye, wire rope receives the problem that huge impact probably damaged or even fracture caused loss of property and incident.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a steady play to rise device for tower machine plays to rise, includes driver's cabin, linkage platform, electric cabinet, plays to rise motor and hoisting mechanism, linkage platform and electric cabinet set up in the driver's cabin, be provided with programmable controller, communication card and converter in the electric cabinet, programmable controller's input and the output end circuit connection of linkage platform, programmable controller's output and the input circuit connection of converter, the communication card sets up on the converter, and its output and programmable controller's input circuit connection, the output of converter and the control end circuit connection who plays to rise the motor, hoisting mechanism sets up beside the rising motor, is connected with the output that plays to rise the motor.
Further, the communication card adopts a modbus communication protocol.
Compared with the prior art, the beneficial effects of the utility model are that:
the crane has the advantages that the crane hoists slowly and stably leave the ground in the process of rising to the ground, the crane cannot shake up and down and left and right, the impact on the crane is effectively reduced, the service lives of the integral steel structure, the hoisting mechanism and the steel wire rope of the crane are prolonged, the safety of the crane in use is improved, and the safety of personnel and articles is ensured.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1-a cab, 2-a linkage table, 3-an electric cabinet, 4-a programmable controller, 5-a communication card, 6-a frequency converter, 7-a lifting motor and 8-a lifting mechanism.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the present invention provides an embodiment: a stable lifting device for lifting a tower crane comprises a cab 1, a linkage table 2, an electric cabinet 3, a lifting motor 7 and a lifting mechanism 8, wherein the linkage table 2 and the electric cabinet 3 are arranged in the cab 1, the linkage table 2 is provided with a plurality of gear switches, the operation of the hoisting mechanism 8 can be manually controlled at different gear speeds, a programmable controller 4, a communication card 5 and a frequency converter 6 are arranged in the electric cabinet 3, the input end of the programmable controller 4 is connected with the output end of the linkage table 2, the output end of the programmable controller 4 is connected with the input end of the frequency converter 6, the communication card 5 is arranged on the frequency converter 6, the output end of the frequency converter is connected with the input end circuit of the programmable controller 4, the output end of the frequency converter 6 is connected with the control end circuit of the lifting motor 7, and the lifting mechanism 8 is arranged beside the lifting motor 7 and is connected with the output end of the lifting motor 7.
The communication card 5 adopts a modbus communication protocol, which is an industrial automation bus communication protocol, supports thousands of industrial intelligent instrument and meter manufacturers for data communication, and simultaneously supports various communication interfaces RS232, RS85, TTL, optical fiber, wireless and other modes, and is widely applied to various industrial automation fields.
The utility model discloses the theory of operation: the gear switch of the linkage table 2 is manually controlled, a control signal is output to the programmable controller 4, meanwhile, the frequency converter 6 outputs current and moment signals to the programmable controller 4 through the communication card 5, the programmable controller 4 controls the operation of the frequency converter 6 according to the control signal output by the linkage table 2 and the current and moment signals fed back by the communication card 5, the frequency converter 6 controls the operation of the lifting motor 7 to drive the lifting mechanism 8 to operate, when the tower crane lifts a heavy object off the ground instantly, namely the current and the moment signals output by the frequency converter 6 are suddenly increased, the programmable controller 4 immediately outputs a signal to control the frequency converter 6 not to operate at the gear speed output by the linkage table 2 but at a lower speed given by a program, at the moment, the heavy object leaves the ground at a slower speed, the crane boom is slowly stressed to be increased and cannot be suddenly loaded, the steel wire rope of the hoisting mechanism 8 gradually and slowly enters a tight state from a loose state, and is also free from large impact force, and the whole hoisting process is stable and safe.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
