Optionally, as shown in fig. 6, a plurality of universal wheels 60 are disposed on the bottom surface of the base 10, one side of the base 10 is further hinged to the amplification base 11 through a hinge, and a plurality of universal wheels 60 or supporting blocks are disposed on the bottom surface of the amplification base 11.

As shown in fig. 6, be provided with a plurality of universal wheels 60 in base 10 bottom surface, the example, base 10 is the rectangle, sets up 4 universal wheels 60 respectively at four angles of the base 10 bottom surface of rectangle, when one side of base 10 still articulates through the hinge has enlarged base 11, can also set up 2 universal wheels 60 in the bottom of enlarging base 11, so, when the utility model discloses a when pipeline lifting device needs to move around, only need provide less driving force, just can make the universal wheel 60 of bottom roll in order to remove this device as required.

Or, when one side of the base 10 is hinged with the amplification base 11 through the hinge, a supporting block can be arranged at the bottom of the amplification base 11, so that in the working state that the amplification base 11 is unfolded, the universal wheel 60 at the bottom of the base 10 is the same as the supporting block at the bottom of the amplification base 11 in height through the support of the supporting block, the working stability is kept, when the device needs to be shifted to move, the amplification base 11 is folded through the hinge firstly, and then the universal wheel 60 is pushed to move so as to realize the movement of the device.

Optionally, as shown in fig. 7, a handle 70 is further fixedly disposed on a side wall of the fixing frame body 21.

Still fixedly at fixed support body 21 lateral wall and being provided with handle 70, as shown in fig. 7, handle 70 sets up on the connecting rod between two fixed support bodies 21, works as the utility model discloses when pipeline carrying device needs to shift to remove, the staff can remove with convenient thrust unit through holding handle 70.

The utility model discloses pipeline carrying device is treating the lift pipeline and carrying out the lift during operation, at first promotes the utility model discloses pipeline carrying device to roll through universal wheel 60 removes the device to the overhead pipeline installation working face.

In the initial state, the height of the pipe bracket 43 of the bracket 40 from the ground of the working surface is about 350mm, and the pipe to be lifted is manually carried and placed in the pipe bracket 43.

The power supply of the electric hoist 50 is connected, the electric hoist 50 starts to rotate positively to drive the steel wire rope to be wound into the winding drum, and the brackets 40 on the two sides of the frame start to slide and lift in the second rail 221 of the first sliding frame body 22 together under the action of the pulley block 30.

When the bracket 40 is lifted to the top of the first sliding frame 22, due to the limiting function of the limiting member, the bracket 40 and the first sliding frame 22 are abutted against each other, and thus cannot be lifted continuously in the second track 221 relative to the first sliding frame 22, at this time, the electric block 50 continues to operate, and the first sliding frame 22 and the bracket 40 are lifted in the first track 211 of the fixing frame 21 in a sliding manner as a whole.

When the pipeline to be lifted is lifted to the required installation height, the power supply of the electric hoist 50 is turned off to stop the operation of the electric hoist 50, the steel wire rope is not wound and pulled, the steel pipe bracket 43 supports the pipeline to be lifted to stay at the installation height, and at the moment, a constructor only needs to move the pipeline to be lifted out of the steel pipe bracket 43 to perform installation operation.

When the pipeline to be lifted is completely removed from the steel pipe bracket 43, the power of the electric hoist 50 can be switched on, and the electric hoist 50 is operated in a reverse direction, so that the second sliding frame body 23 and the bracket 40 can be retracted to the initial position, so as to perform the next lifting operation.

The embodiment of the present invention provides a pipeline lifting device, wherein the second sliding frame body 23 can extend out relative to the first sliding frame body 22 through the second track 221 arranged on the first sliding frame body 22 by the movement of the second sliding frame body 23 in the second track 221 to provide a first lifting stage, so as to make the bracket 40 arranged on the second sliding frame body 23 for supporting the pipeline to be lifted lift high, when the second sliding frame body 23 is lifted to the predetermined position, the movement track of the second sliding frame body 23 relative to the first sliding frame body 22 is limited by the limiting action of the limiting component arranged at the end of the first sliding frame body 22 away from the fixed frame body 21, when the lifting action force is continuously provided, the first sliding frame body 22 can be further lifted along the first track 211 on the fixed frame body 21, thereby driving the second sliding frame 23 fixed at a position with the first sliding frame body 22 to lift together, to provide a second stage of the lifting phase. Through the pulley block setting of fixed pulley and movable pulley, can directly act on second slip support body 23 with power through the connection of wire rope, the required power of pipeline is treated to the effectual promotion that alleviates.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
