Abstract
A lifting rod cable winding and unwinding device comprises a shell, wherein a cable inlet and a cable outlet are formed below the shell, a sliding way in the vertical direction is formed in the shell, a slider capable of sliding on the sliding way is arranged on the sliding way, movable pulleys with the axes parallel to each other are arranged on the left and right of the slider respectively, fixed pulleys with the axes parallel to the axes of the movable pulleys are arranged below the interior of the shell and between the left and right movable pulleys, a steering roller is arranged on the outer side of the cable inlet below the shell, the slider is connected with a traction rope, the traction rope is connected with a winch, the winch is provided with a roller, and the roller is connected with a speed reducer through a shaft. The lifting rod cable winding and unwinding device is fixed below an electric lifting rod, a cable led out from the lower end of a bottom pipe of the electric lifting rod is led into the shell through the steering roller and the cable inlet and sequentially winds through the movable pulleys and the fixed pulleys, the shaft of the hauling rope winch is connected with a shaft of a motor of the electric lifting rod through a transmission device, and according to the design of the transmission device, the winding and unwinding length of the cable wound and unwound by the winch is made to be synchronous with the lifting length of the electric lifting rod. According to the lifting rod cable winding and unwinding device, the cable can be wound and unwound synchronously with lifting of the electric lifting rod.
Description
Technical field
The utility model relates to a kind of and corollary apparatus electric lifting rod, particularly the supporting cable putting apparatus of a kind of and electric lifting rod.
Background technology
The electric lifting rod with certain weight lifting ability is for erecting a television antenna aloft fast or the electrical equipment such as lamps and lanterns.Electric lifting rod has the multistage pipe being nested together, and in multistage pipe, pipe of outermost is bottom tube, and a pipe in is push pipe, and remaining pipe is inner tube, and bottom tube is fixed on base, has reductor on base, and reductor is connected with motor.The upper end of push pipe is mounted with the electrical equipment such as antenna or lamps and lanterns.Motor can drive the multistage pipe of electric lifting rod progressively to stretch out or progressively indentation to realize the lifting of lifting bar.For to antenna or lamps and lanterns energising and information, in the multistage pipe of electric lifting rod, there is cable, the upper end of cable is connected on the electrical equipment such as antenna or lamps and lanterns of push pipe upper end, and draw from the lower end of bottom tube the lower end of cable.After lifting bar rises, the cable in the multistage pipe stretching out is longer, and after lifting bar is fallen, the cable in the multistage pipe of indentation is shorter.When allowing lifter rod lifting, cable in multistage pipe is synchronizeed extended or retracted with multistage pipe, will there be the cable putting apparatus that can synchronously discharge and receive with the lifting of lifting bar cable the lower end of electric lifting rod, cable putting apparatus is in the time that lifting bar rises, synchronize and discharge cable with the elongation of multistage pipe, in the time that lifting bar is fallen, synchronize and receive cable with the indentation of multistage pipe.
In prior art, there is no the cable putting apparatus supporting with electric lifting rod, when electric lifting rod lifting, storage and release cable are pretty troublesome things.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes lifting bar cable putting apparatus a kind of and that electric lifting rod is supporting.
The utility model is realized with the following method.
Lifting bar cable putting apparatus has housing, there is cable import and export the below of housing, in housing, have along upper and lower to slideway, on slideway, have the slide block that can slide on slideway, there is respectively the parallel movable pulley of axis the left and right sides of slide block, between below in housing, left and right moving pulley, there is the axis fixed pulley parallel with the axis of movable pulley, there are slewing rollers in the cable access outside of housing below, and slide block is connected with hauling rope, and hauling rope is connected with winch, winch has cylinder, and drum shaft is connected with reductor.
After winch of the present utility model is wrapped in hauling rope on cylinder, slide block can be mentioned, allow the distance between movable pulley and fixed pulley strengthen, the hauling rope being wrapped on cylinder is discharged, can allow slide block fall, allow the distance between movable pulley and fixed pulley reduce.
When installation, the utility model is fixed on to the below of electric lifting rod, the cable of drawing from electric lifting rod bottom tube lower end is introduced in housing through slewing rollers and cable access, walk around successively after a movable pulley, fixed pulley and another movable pulley, be fixed on the cable outlet of housing below and draw from housing below, the axle of hauling rope winch is connected with the axle of electric lifting rod motor by driving device, and driving device is designed to allow the length of winch releasing winch cable and the lifting length synchronised of electric lifting rod.
In the time that electric lifting rod is retracted, winch is wound into hauling rope on cylinder, and slide block is mentioned to housing top, and cable is incorporated between the movable pulley and fixed pulley that in housing, distance is larger.While rising electric lifting rod, starter motor, the multistage pipe of lifting bar extends, winch discharges the hauling rope being wrapped on cylinder simultaneously, hauling rope slide block declines gradually, allows cable that the utility model discharges and the elongation of multistage pipe synchronously extend, until lifting bar is risen; When decline electric lifting rod, starter motor, the multistage pipe of lifting bar is retracted, and winch is wrapped in hauling rope on cylinder simultaneously, and hauling rope slide block rises gradually, allows the retraction of the utility model and multistage pipe synchronously receive cable, until lifting bar is retracted.
The utility model can support the use with electric lifting rod, realizes and synchronously discharges with the lifting of electric lifting rod and receive cable.
Below in conjunction with accompanying drawing, the utility model is further described.
Brief description of the drawings
Fig. 1 looks schematic diagram according to the master of a kind of lifting bar cable putting apparatus of scheme of the invention proposition of the present utility model;
Fig. 2 is the schematic side view of Fig. 1;
Fig. 3 is that the master of winch looks schematic diagram.
Detailed description of the invention
In Fig. 1 ~ Fig. 3, lifting bar cable putting apparatus has housing 1, the below of housing has cable to enter, outlet 2, 3, in housing, have along upper, the slideway 4 of lower direction, on slideway, there is the slide block 5 that can slide on slideway, there is respectively the parallel movable pulley of axis 6 left and right sides of slide block, 7, below in housing, between left and right moving pulley, there is the axis fixed pulley parallel with the axis of movable pulley 8, there are slewing rollers 9 in the cable access outside of housing below, slide block is connected with hauling rope 10, hauling rope is by wheel flutter 14, 15 are connected with winch 11, winch has cylinder 12, drum shaft is connected with reductor 13.
The utility model is fixed on the below of electric lifting rod 16, the cable 17 of drawing from electric lifting rod bottom tube lower end is introduced in housing through slewing rollers and cable access, walk around successively after a movable pulley, fixed pulley and another movable pulley, be fixed on the cable outlet 18 of housing below and draw from housing below, the axle of hauling rope winch is connected with the axle of electric lifting rod motor by driving device, and driving device is designed to allow the length of winch releasing winch cable and the lifting length synchronised of electric lifting rod.
