Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.

Referring to fig. 1 and 2, an installation device for a pipeline in a crane beam is composed of a crown block 2, a roller 3, a wire rope 5, a hook 6 and the like, and is used for transporting the pipeline 3 to an installation position inside the crane beam 1 through cooperation of an aerial worker 7 and a ground worker 8.

The fixed pulley block 2 consists of two M100 fixed pulleys with the same specification, and is fixed in the middle of the full-length span of the crane beam through welding, and the full-length span of the crane beam is very large and can reach hundreds of meters. The two ends of the crane beam in the full-length direction are respectively provided with a roller bracket 9 perpendicular to the full-length direction, and the rollers 4 are sleeved on the roller brackets 9 and fixed at the two ends of the crane beam in the full-length direction through the roller brackets 9. Set up two wire rope 5 altogether, every wire rope one end is equipped with couple 6, and the one end that has couple 6 is passed behind pipeline 3 and is colluded on pipeline 3, and the other end is the free end, walks around the fixed pulley pivot and then hangs down subaerial, is by the pulling of ground operation personnel 8, drives pipeline 3 and removes. When the pipeline 3 moves, rolling friction is generated between the pipeline and the roller 4, and the rolling friction force is smaller than the friction force generated by direct contact, so that labor is saved when the pipeline is pulled.

A method for installing a pipeline in a crane beam is implemented by the following steps:

s1: the fixed pulley block 2 is fixed in the middle of the direction of the full length span of the crane beam in a welding mode, correspondingly, two rollers 4 are arranged at two ends of the direction of the full length of the crane beam respectively, the installation positions of the fixed pulley block 2 and the rollers 4 are lower than the installation position of the pipeline 3 respectively, the fixed pulley block 2 is composed of two M100 fixed pulleys, two steel wire ropes 5 are provided simultaneously, one end of each steel wire rope 5 is a free end, the other end of each steel wire rope is connected with a hook 6, the free end of each steel wire rope 5 penetrates through the fixed pulleys and falls to the ground to be pulled by ground operating personnel 8, and one end of each connecting hook 6 is temporarily hung at an. The fixed pulley group 2 in the S1 can also be directly replaced by two M100 fixed pulleys arranged in the middle of the full-length span of the crane beam.

S2: the two groups of cranes 10 respectively hoist the pipeline 3 from two ends of the through length direction of the crane beam, each end is provided with an aerial worker 7, one end of the pipeline 3 is placed on the roller 4, the aerial worker 7 assists in preventing the pipeline 3 from colliding with the crane beam system when entering the crane beam 1, the aerial worker 7 enables one end of the steel wire rope 5 with the hook 6 to penetrate through the pipeline 3, the hook 6 is hooked on the pipeline 3, and the other end of the steel wire rope penetrates through the fixed pulley and falls to the ground. Each section of pipeline 3 is obtained by pre-assembling two single sections of pipelines with the length of 12m on the terrace.

S3: two groups of ground operating personnel 8 hold the steel wire rope 5 below the fixed pulley block, pull the steel wire rope 5 from different directions to make the fixed pulley roll, pull the pipeline 3 to advance towards the inside of the crane beam, the roller also starts to roll, reduce the force required for pulling the pipeline, in the process, the high-altitude operating personnel prevent the pipeline 3 from touching the crane beam system through auxiliary operation, when the pipeline 3 exceeds the roller by more than half of the length, the hoisting of the pipeline 3 by the crane 10 is released.

S4: when the pipeline 3 approaches the pipeline bracket inside the crane beam, the high-altitude operator 7 lifts one end of the pipeline to enable the lifted end to abut against the pipeline bracket at the installation height.

S5: the ground operator 8 continues to pull the steel wire rope 5, so that the pipeline 3 is completely moved from the roller 4 to the pipeline bracket 7; and then the pipeline 3 moves along the pipeline bracket, in the moving process, the high-altitude operation personnel 7 continuously cooperate with the pipeline bracket, under the condition that the advancing of the pipeline is blocked, the pipeline is lifted to the position where the pipeline can pass through smoothly, and after the pipeline reaches the specified installation position, welding is carried out by welding personnel.

Through the utility model discloses an installation device and installation method, can rotate the pulling force of applying operating personnel through wire rope with the help of the fixed pulley and use the pipeline on, the roll through the cylinder reduces frictional resistance to save the manpower, accelerated the construction progress, avoid the pipeline to touch crane beam system through industry control operation personnel's assistance, improved the piping erection quality.

The above description is only the preferred embodiment of the present invention. Various modifications and equivalent changes may be made by those skilled in the art without departing from the spirit and scope of the present invention, and such modifications and changes are intended to be included within the scope of the present invention.
