Abstract
A labor-saving device of a screw jack comprises the screw jack, wherein a rocking bar hole in the screw jack is connected with an auxiliary shaft of a reduction box, a main shaft of the reduction box is connected with a motor, the screw jack, the motor and the reduction box are fixed on a machine frame, and an electric control switch is arranged on the machine frame. According to the labor-saving device of the screw jack, the structure that the motor is connected with the reduction box and the reduction box drives the screw jack is adopted, and meanwhile the electric control switch which is convenient for people to operate is arranged on the machine frame, so that ascending and descending of the screw jack are controlled conveniently without consuming labor.
Description
Technical field
The utility model belongs to the flight-line maintenance field, is specifically related to a kind of lifting screw lifting screw work-saving device for light textile industry deflector roll maintenance usefulness.
Background technology
Now, be used for the jack of flight-line maintenance, the lifting screw of keeping in repair usefulness especially for light textile industry deflector roll needs manpower to drive in use, has the problem inconvenient and that waste time and energy of using like this.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of handled easily that provides and can effectively save the lifting screw work-saving device of manpower.
The purpose of this utility model is achieved in that
A kind of lifting screw work-saving device, it comprises lifting screw, and the rocking bar hole of lifting screw is connected with the countershaft of reductor, and the main shaft of reductor is connected with motor; Lifting screw, motor, reductor are fixed on the frame; Frame is provided with electric-controlled switch.Operating personal reaches the purpose of control motor forward and reverse by the control to electric-controlled switch, drives the purpose that lifting screw advances and shrinks thereby reach.
Above-mentioned reductor is preferably formed by first class reducer and 2-level reducer cascade, and first class reducer and 2-level reducer are formed by the belt cascade by the axle that is positioned at reductor one side, can guarantee that like this countershaft has more suitable rotating speed.
Above-mentioned motor preferred triple-phase double-speed motor, it can realize just changeing well, the function of counter-rotating and speed governing, reaches the purpose of convenient control lifting screw.
The utility model has been obtained following technique effect:
At first, the utility model has adopted motor to be connected with reductor, and reductor drives the structure of lifting screw, and is provided with the electric-controlled switch that is convenient for people to operate in frame, can make things convenient for and control without labor intensive ground rising and the decline of lifting screw; Secondly, reductor adopts the structure that is formed by first class reducer and 2-level reducer cascade, can guarantee that countershaft has suitable rotating speed; Again, motor adopts the three-phase double-speed motor, can realize well just changeing, the function of counter-rotating and speed governing, thereby reach the convenient purpose of controlling lifting screw.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of lifting screw work-saving device as shown in Figure 1, it comprises lifting screw 1, and the rocking bar hole of lifting screw 1 is connected with the countershaft of reductor 2, and the main shaft of reductor 2 is connected with motor 5; Lifting screw 1, motor 5, reductor 2 are fixed on the frame 7; Frame 7 is provided with electric-controlled switch 6, and operating personal reaches the purpose of control motor forward and reverse by the control to electric-controlled switch, drives the purpose that lifting screw advances and shrinks thereby reach.
When adopting said structure, the weight that needs jack-up is placed this device top, just can control rising and the decline of lifting screw 1 very easily by the control electric-controlled switch, and can adjust the speed that lifting screw 1 rises and descends according to the situation of reality.
