Embodiment Construction

[0016] Such as figure 1 with figure 2 As shown, a railway sound barrier elevator of the present invention includes a hoisting mechanism, a motor, a controller and a battery connected in sequence, the battery provides a power source for the motor, and the controller is used to control the lifting of the hoisting mechanism , the motor is used to drive the lifting mechanism to lift. The lifting mechanism includes a base assembly 1, a lifting hook 2, a worm gear screw lifter 3, a screw assembly 4, and a screw support frame. The lifting hook 3 is arranged on both sides of the bottom of the base assembly 1, and The cotter pin 12 and the nut 13 are flexibly connected with the base assembly 1, and can be rotated 90 degrees in the horizontal direction, that is, the lifting hook is usually stored at the bottom of the base assembly, and the front end of the lifting hook is rotated 90 degrees in the horizontal direction when in use. The front of the base assembly, so as to support the ...

Abstract

Disclosed is a sound barrier lifter for railways. On condition of keeping a lead screw fixed, a lithium iron phosphate battery is used as a power source, a direct-current speed reduction motor is used as power to drive a worm gear screw lifter to rotate, a controller controls the direct-current speed reduction motor to rotate forwards and backwards and stop to drive the worm gear screw lifter to move vertically along the lead screw, and accordingly a base assembly connected on the worm gear screw lifter and a lifting hook arranged on the base assembly are driven to lift a sound barrier vertically. The concept that a conventional lifter lifts along with rotation and vertical moving of a nut or rotation and moving of the lead screw is substituted by the mode that the lead screw is fixed and the worm gear screw lifter is driven to move by rotation of the nut and lift the sound barrier. Further, the sound barrier lifter for railways has the advantages of simple structure, convenience in carrying, operation and maintenance, safety, reliability and capability of being assembled and dissembled quickly.

Description

technical field [0001] The invention relates to a lifting device, in particular to a railway sound barrier lifter. Background technique [0002] In recent years, as my country's high-speed railways, intercity high-speed railways and passenger dedicated lines have been put into operation one after another, in order to reduce the noise generated between the wheels and rails during the operation of high-speed EMUs that will harm residents, so when passing through urban areas, suburbs and along the lines A large number of sound barriers are set up on both sides of the line in the village to attenuate and prevent the spread of noise. The size of a single section of the sound barrier is 2000×500×70mm, and the mass is about 35kg. After the sides of both ends and the upper and lower sides are sealed with rubber strips, the upper and lower sides are sequentially snapped into the groove of the I-steel column welded by steel plates. The foundation of the I-beam column is divided into t...
