CN202098983U - Movable portal derrick device - Google Patents

Abstract

The utility model discloses a movable portal derrick device, which comprises a supporting rod and an ejecting rod. Universal wheels are mounted at the bottom of the supporting rod, a hoisting hole is mounted on the ejecting rod, and a lifting device is arranged in the hoisting hole. The universal wheels which are mounted at the bottom of the supporting rod can move optionally, valves and pipelines to be assembled are moved by the lifting device in the hoisting hole, and the supporting rod is telescopic so as to facilitate operation of the lifting device. When the chemical pipelines are in construction, the movable portal derrick device is capable of satisfying needs of assembly of different planes and different valve groups, low in cost and high in efficiency.

Description

A kind of travelling gantry pole device

Technical field

The utility model relates to a kind of travelling gantry pole device.

Background technology

In chemical pipeline construction, usually can run into valving pipeline group in a row to the time, the above valve of DN100 often need by elevator machinery could the completion group to putting in place, not only cost is high, and efficient is low, uses inconvenient.

The utility model content

The technical matters that the utility model will solve is that the above valve of DN100 often need be by elevator machinery ability completion group to putting in place, and the cost-effective rate is low, uses inconvenience, and a kind of travelling gantry pole device is provided.

The technical scheme of the utility model is: a kind of travelling gantry pole device, comprise strut bar and push rod, and cardan wheel is equipped with in said strut bar bottom, and hole for hoist is housed on the push rod, and jacking system is housed in the hole for hoist.

Said strut bar is an expansion link.

Said jacking system is hoist ceiling crane or bottle gouard moved by hands or adopts assembly pulley.

The beneficial effect of the utility model is: cardan wheel is equipped with in the strut bar bottom, can arbitrarily move, and moves through the jacking system in the hole for hoist and wants stack-mounted valve and pipeline; Strut bar can stretch; The operation of easy of rise device when chemical pipeline is constructed, can be satisfied the right needs of the different valving groups of Different Plane; Cost is low, and efficient is high.

The specific embodiment

A kind of travelling gantry pole device comprises retracted support bar 2 and push rod 3, and cardan wheel 1 is equipped with in said strut bar bottom, and hole for hoist 4 is housed on the push rod 3, and jacking system 5 is housed in the hole for hoist.

During use; Hang up jacking system in the hole for hoist in the middle of the pole, hang up properly nylon lifting rope below the jacking system, tie up valve or pipeline gets final product with nylon lifting rope; Each position be can move to arbitrarily in the Different Plane work layer then, valve and pipeline stack-mounted needs satisfied.

Said jacking system is hoist ceiling crane or bottle gouard moved by hands or adopts assembly pulley.

Claims (3)

1. travelling gantry pole device is characterized in that: comprise strut bar and push rod, cardan wheel is equipped with in said strut bar bottom, and hole for hoist is housed on the push rod, and jacking system is housed in the hole for hoist.
