The lifter is a mechanical device for logistics transportation, is a lifter which is widely applied at present and mainly comprises an oil cylinder jacking device, a screw rod lifting device or a chain direct lifting device. Because the weight of the material is heavier, the lifting devices need power with larger power to drive, the energy consumption is larger, and the energy-saving requirement is not met.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem the technical scheme of the utility model be, a elevating system for PCB board material car, which comprises a frame, the frame divide into lift workspace and lift control district with the lift, the lift workspace includes fork truck frame, the supporting leg swing joint of fork truck frame and frame, the lift control district includes the motor, the motor is connected with the hold-in range, the hold-in range passes through the fixed block and is connected with fork truck frame.

Further, the lifting control area further comprises a balancing weight, and the balancing weight is connected with the two sides of the forklift frame through a first steel wire rope and a second steel wire rope.

Furthermore, the balancing weight is movably connected with an optical axis arranged on the frame through a bearing.

Furthermore, the first steel wire rope is connected with the forklift frame and the balancing weight through a first pulley and a second pulley which are arranged on the top of the frame.

Furthermore, the steel wire rope II connects the forklift frame and the counterweight block through a pulley III and a pulley IV which are arranged at the top of the lifting control area.

Furthermore, the forklift frame is connected with a square rail arranged on the supporting leg of the frame through a sliding block.

Utilize the technical scheme of the utility model an elevating system for PCB board material car can be according to the speed of taking of workman to the PCB board, and the lift moves downwards automatically to make the workman all take at the horizontality at every turn, it is very convenient.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, as shown in fig. 1-3, a lifting mechanism for a PCB board material vehicle comprises a frame 1 dividing the lifting machine into a lifting work area 2 and a lifting control area 3, the lifting work area 2 comprises a forklift frame 201, the forklift frame 201 is movably connected with a square rail 203 arranged on a support leg of the frame through a slider 202, the lifting control area 3 comprises a motor 301 arranged at the bottom of the frame, the motor 301 is connected with a synchronous belt 302, the synchronous belt 302 is connected with the forklift frame 201 through a fixed block 303, the lifting control area further comprises a counterweight block 304, the counterweight block 304 is connected with two sides of the forklift frame 201 through a first steel wire rope 204 and a second steel wire rope 205, the first steel wire rope 204 connects the forklift frame 201 with the counterweight block 304 through a first pulley 206 and a second pulley 207 arranged at the top of the frame, the second steel wire rope 205 connects the forklift frame 201 with the counterweight block 304 through a third pulley 208 and, the balancing weight 304 is movably connected with an optical axis 306 arranged on the frame through a bearing 305.

During operation, on pushing into the fork truck frame of lift with the material car, starter motor, material dolly will be promoted the highest point, and material bottom material and transfer chain level this moment, the workman can be convenient take off, and the balancing weight is located the lower extreme this moment. According to workman's speed of taking, the automatic downward movement of lift, the balancing weight upwards moves, and the balancing weight can the material dolly exert decurrent power to reduce the effort of hold-in range, thereby can make the motor provide less power and just can realize the purpose of drive material car, and then reduced the noise that too big power caused, the energy saving simultaneously, reduce cost.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
