Abstract
The utility model provides a lifting rod depending on traction of a steel wire rope to rise and fall. The lifting rod depending on the traction of the steel wire rope to rise and fall comprises lifting section rods, pulleys, a rising traction steel wire rope, and a unidirectional rotating winch. The head end of the rising traction steel wire rope is connected with the unidirectional rotating winch, and the tail end of the rising traction steel wire rope penetrates through the pulleys which are arranged on the lifting section rods and is fixed on an second section rod upper end on the top of the lifting rod which can be risen when the unidirectional rotating winch rotates. The lifting rod depending on the traction of the steel wire rope to rise and fall is characterized in that a falling traction steel wire rope is connected with a first section rod lower end on the top of the lifting rod, the other end of the falling traction steel wire rope is connected with a newly added winch, and the lifting rod can fall when the newly added winch rotates. The lifting rod depending on the traction of the steel wire rope to rise and fall uses the falling traction steel wire rope to enable the lifting rod to fall having nothing to do with he weight of the lifting rod, neither a small amount of deformation of the lifting rod nor increasing of seal damping between the lifting section rods can influence the falling of the lifting rod, and the falling of the lifting rod can be guaranteed when tension of the falling traction steel wire rope is larger than falling resistance.
Description
Technical field
The utility model relates to a kind of liter and falls the lifting bar that all relies on rope traction.
Background technology
In many occasions, it is too high that communication antenna, discharging rod etc. is subjected to that environmental constraints can not install, and must reach a certain height when work, and this just needs to use a kind of lifting bar that can rise and fall.Existing lifting bar is by the circular or square material sleeve of the different bores of more piece together, mixes seal ring, haulage cable, winch and forms a jacking system.When winch tightened up steel rope, the bar that is nested together just a section rise came, and when steel rope loosens, rose the bar that comes and utilized the gravity of self to fall, and used widely in each field.Because the impact of environmental factor, as the inclement weathers such as sleet, dust storm appear, or collided with in the transportation etc., in sealing place of every joint of lifting bar, sliding resistance will increase, and the phenomenon of falling often occurs, the key reason of problem is to rely on deadweight to descend, when conducting oneself with dignity less than the decline resistance, lifting bar just can not lower, and just can finish decline when conducting oneself with dignity greater than the decline resistance.
Summary of the invention
The purpose of this utility model, a kind of liter will be provided and fall the lifting bar that all relies on rope traction, can guarantee that lifting bar still can rise and fall reliably under abnormal condition, satisfy lifting bar in the application in the fields such as communication, lightning protection, can in needs, accurately go up, can lower timely after task is finished.
The first most preferred embodiment of the present utility model: a kind of liter and fall the lifting bar that all relies on rope traction, it comprises the lifting pole, pulley, the rising haulage cable, the winch of single direction rotation, the head end of rising haulage cable is connected with the winch of single direction rotation, the tail end of rising haulage cable passes is located at the upper end that is fixed on lifting bar top the second pole behind the set pulley of each pole, rotate the winch of single direction rotation, lifting bar is risen, it is characterized in that: in the lower end of lifting bar top the first pole, connect a decline haulage cable, the other end of this decline haulage cable is connected with the winch of newly establishing, the winch that rotation is newly established can make lifting bar descend.
The second most preferred embodiment of the present utility model: the winch coaxial position at single direction rotation is set up the sprocket wheel with single direction rotation function, and by one transmit chain be socketed respectively this winch and newly establish winch; When the sprocket wheel that clickwise has the single direction rotation function, the winch that this sprocket wheel drives single direction rotation is in the state of articulating, and the winch of single direction rotation tightens up the rising haulage cable, and each pole is opened to cheat upwards and risen; When the sprocket wheel that the inhour rotation has the single direction rotation function, this sprocket wheel drives the winch of newly establishing and is in the state of articulating, and the winch of newly establishing tightens up the decline haulage cable, the lifting bar of leaving behind.
Rising haulage cable described in the utility model and decline haulage cable are all hidden in the lifting pole; When described rising haulage cable and decline haulage cable stop to draw, all there is locking mechanism to lock.
The beneficial effects of the utility model are, utilize the decline haulage cable that lifting bar is descended, irrelevant with the weight of lifting bar, therefore no matter be that the sealing damping that lifting bar occurs between in a small amount deformation or the pole increases, the pulling force of decline haulage cable can not affect the decline of lifting bar, as long as just can guarantee that greater than the decline resistance lifting bar normally descends.
Description of drawings
Fig. 1 is the lifting bar scheme drawing that relies on deadweight to descend in the prior art.
Fig. 2 is the utility model the first most preferred embodiment scheme drawing.
Fig. 3 is the utility model the second most preferred embodiment scheme drawing.
Among the figure: 1. lifting pole, 2. pulley, 3. rising haulage cable, the 4. winch of single direction rotation, 5. the upper end of the second pole, the sprocket wheel that 6. has the single direction rotation function 7. transmits chain, 8. the winch of newly establishing, 9. decline haulage cable, the 10. lower end of the first pole.
The specific embodiment
The first most preferred embodiment: as shown in Figure 2, a kind of liter and fall the lifting bar that all relies on rope traction, it comprises the winch 4 of lifting pole 1, pulley 2, rising haulage cable 3, single direction rotation, the head end of rising haulage cable 3 is connected with the winch of single direction rotation 4, the tail end of rising haulage cable 3 passes is located at the upper end 5 that is fixed on lifting bar top the second pole behind the set pulley of each pole, rotate the winch 4 of single direction rotation, lifting bar is risen.In the lower end 10 of lifting bar top the first pole, connect a decline haulage cable 9, the other end of this decline haulage cable 9 is connected with the winch of newly establishing 8, rotates the winch 8 of newly establishing, and lifting bar is descended.
The second most preferred embodiment: a kind of liter described in the utility model and fall the lifting bar that all relies on rope traction, as shown in Figure 3, it comprises lifting pole 1, pulley 2, rising haulage cable 3, the winch 4 of single direction rotation, the head end of rising haulage cable 3 is connected with the winch of single direction rotation 4, the tail end of rising haulage cable 3 passes is located at the upper end 5 that is fixed on lifting bar top the second pole behind the set pulley of each pole, winch 4 coaxial positions at single direction rotation are set up the sprocket wheel 6 with single direction rotation function, and transmit the winch 8 that chain 7 is socketed respectively this winch and newly establishes by one; Set up a decline haulage cable 9, an end of this decline haulage cable 9 connects the winch 8 of newly establishing, the lower end 10 that the other end connects lifting bar top the first pole; When the sprocket wheel 6 that clickwise has the single direction rotation function, the winch 4 that this sprocket wheel drives single direction rotation is in the state of articulating, and the winch 4 of single direction rotation tightens up rising haulage cable 3, and each pole is opened to cheat upwards and risen; When the sprocket wheel 6 that the inhour rotation has the single direction rotation function, this sprocket wheel drives the winch 8 of newly establishing and is in the state of articulating, and this moment, the winch 4 of this sprocket wheel drive single direction rotation was in sliding mode, and the winch 8 of newly establishing tightens up decline haulage cable 9, the lifting bar of leaving behind.
