Referring to fig. 1 and fig. 2, a guy rope formula power catwalk base lifting devices, includes catwalk base 1 and the tubular product carriage 2 that is located catwalk base 1 top, its characterized in that: lifting devices 6 are arranged at the front end and the rear end of the catwalk base 1; the lifting device 6 comprises a first push cylinder 61, a second push cylinder 62 and a V-shaped frame 63; the lower ends of the first pushing cylinder 61 and the second pushing cylinder 62 are fixed on the base of the catwalk base 1; the two sides of the V-shaped frame 63 are respectively provided with a sliding groove 65 and a hinge point; the free end of the first push cylinder 61 is clamped and embedded in a sliding groove 65 on one side of the V-shaped frame 63; the free end of the second push cylinder 62 is hinged with the hinge point on the other side of the V-shaped frame 63; supporting seats 64 are arranged below two sides of the V-shaped frame 63 and above the corresponding first pushing cylinder 61 and the second pushing cylinder 62; when the free ends of the first pushing cylinder 61 and the second pushing cylinder 62 are at the lowest ends; both sides of the V-shaped frame 63 are embedded in the supporting seat 64.

Referring to fig. 2 and 3, auxiliary devices 7 are arranged on two sides of the V-shaped frame 63; the auxiliary device 7 comprises a tilt push cylinder 71, an outer claw sleeve 72, an inner hook claw 73 and a limit plate 74; the limiting plate 74 is fixedly arranged on the catwalk base 1; the inclined pushing cylinder 71 is inclined outwards, the lower end of the inclined pushing cylinder 71 is hinged to the base of the catwalk base 1, and the free end of the inclined pushing cylinder 71 is hinged to the lower end of the outer side of the outer claw sleeve 72; the lower end of the inner side of the outer claw sleeve 72 is hinged with a limiting plate 74; the inner hook claw 73 is embedded in the outer claw sleeve 72. The inner claw 73 and the outer claw sleeve 72 are both provided with a connecting groove 77, and the two connecting grooves 77 are fixedly connected through a pin shaft. A plurality of limiting holes 76 are formed above the limiting plate 74, and a limiting column 75 is inserted into any limiting hole 76. A plurality of fixing slots 78 which are distributed at equal intervals are arranged on the side body of the inner hook claw 73.

The working principle and the using method are as follows:

the pipe is conveyed to the upper part of the catwalk base 1 through the conveying support, enters the V-shaped frame 63, and then the first pushing cylinder 61 and the second pushing cylinder 62 push simultaneously, so that the V-shaped frame 63 integrally rises, lifting of the pipe is realized, and then the pipe is grabbed through the mechanical clamping jaws on the pipe conveying frame 2.

The process of the push delivery of the tube is illustrated in the upper left and right views of fig. 4.

When the pipe in the V-shaped frame 63 needs to be unloaded, the first pushing cylinder 61 and the second pushing cylinder 62 move oppositely, so that the V-shaped frame 63 tilts, and the normal operation of the equipment is ensured because the upper end of the first pushing cylinder 61 is embedded and slides in the sliding groove 65 of the V-shaped frame 63. Reference is made here to the left and right lower views in fig. 4.

When the pipe is used for pipe installing and pipe unloading, the inclined pushing cylinder 71 stretches out and draws back, so that the outer claw sleeve 72 can move up and down, the pipe installing and pipe unloading assisting effect is achieved, and meanwhile when the outer claw sleeve 72 moves upwards, the pipe is prevented from falling off.

Further, the inner claw 73 and the outer claw sleeve 72 are detachable, so that when the device is not used, the outer claw sleeve 72 can be detached and then fixed on the side frame of the catwalk base 1 through the fixing slot 78 on the side body, as shown in fig. 1.

Further, by additionally arranging the supporting seat 64, when the first pushing cylinder 61 and the second pushing cylinder 62 are completely contracted, the weight of the V-shaped frame 63 is borne on the supporting seat 64, and the safety and the reliability in the transportation process are improved.
