In the figure, 1, an internal upright post; 2. an outer column; 3. a guide wheel; 4. an upper cross member; 5. a lower pulley; 6. an upper pulley; 7. a small hoisting device; 8. an upper limiting block; 9. a lower limiting block; 10. a wire rope; 11. a fixed block; 12. a lower electric control limit switch; 13. an upper electric control limit switch.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

the first embodiment is as follows: the remote control type automatic lifting height limiting rod comprises small-sized hoisting equipment 7, a steel wire rope 10 and a group of internal upright columns 1, wherein pulleys are arranged on the internal upright columns 1, an upper cross beam 4 is arranged at the top of each internal upright column 1, external upright columns 2 capable of moving up and down are arranged outside the internal upright columns 1, fixing blocks 11 are arranged on the external upright columns 2, one end of the steel wire rope 10 penetrates through the pulleys to be connected with the small-sized hoisting equipment 7, and the other end of the steel wire rope 10 is connected with the fixing blocks 11; a guide wheel 3 is arranged between the inner upright post 1 and the outer upright post 2.

In the manufacturing process of the embodiment, the group of internal upright columns 1 comprises two internal upright columns 1, and the distance between the two internal upright columns 1 is determined according to the road width limitation; two sides of the upper and lower ends of the internal upright post 1 are respectively provided with a bearing type guide wheel 3; when the device is installed, the inner upright post 1 is fixed on a ground foundation, then the outer upright post 2 is sleeved on the inner upright post 1, and the outer upright post 2 is guided to be vertical to the inner upright post 1 through the guide wheel 3; one end of the upper cross beam 4 is inserted into the external upright stanchion 2 through a pin shaft for fixing, and the other end of the upper cross beam 4 is movably connected with the external upright stanchion 2 through a U-shaped seat.

Example two: as shown in fig. 1 to 3, the inner upright posts 1 are divided into two groups, that is, two height-limiting rods are respectively arranged at two sides of the road width limitation, and an upper limiting block 8 and a lower limiting block 9 which are matched with the outer upright posts 2 are respectively arranged at the upper end and the lower end of the inner upright posts 1; an upper electric control limit switch 13 and a lower electric control limit switch 12 which are matched with the upper limit block 8 and the lower limit block 9 are arranged on the inner upright post 1; the other steps are the same as those of the embodiment.

In the manufacturing process of the embodiment, the small-sized hoisting equipment 7 adopts a winch, the winch is fixed between two internal upright posts 1, the upper end and the lower end of each internal upright post 1 are respectively provided with an upper pulley 6 and a lower pulley 5, and a steel wire rope 10 is connected with the upper pulley 6 through the lower pulley 5 and then is connected with a fixing block 11 on the external upright post 2 to be locked and fixed.

The utility model discloses when using, can use remote controller operation limit for height pole, the corotation of remote controller control hoist engine or reversal. When the lifting operation is needed, the winch positively rotates to drive the steel wire rope 10 to pull up and lift the external upright post 2, and the upper cross beam 4 fixed on the external upright post 2 is driven to lift together, so that the purpose of integrally lifting the height limiting rod is achieved. When the height-limiting rod reaches the preset height, the upper electric control limit switch 13 controls the circuit to be powered off and stop rising, the remote controller rising key loses the effect, and in order to prevent accidents, the upper end of the inner upright post 1 is provided with the fixed upper limit block 8 to prevent the outer upright post 2 from sliding out.

When the height limiting rod needs to be operated to descend, the winch reversely rotates to drive the steel wire rope 10 to descend the external upright post 2 and drive the upper cross beam 4 fixed on the external upright post 2 to descend together, and the purpose of integrally descending the height limiting rod is achieved. When the height limiting rod descends to a preset height, the lower electric control limit switch 12 cuts off the power of the control circuit and stops descending, the descending key of the remote controller loses the function, and in order to prevent accidents, the lower part of the inner upright post 1 is provided with a fixed lower limit block 9 to prevent the outer upright post 2 from sliding out.
