Embodiment 1

[0048] Embodiment one, step D, comprises the following steps:

[0049] d1, pull the front beam to the installation position 11 of the front beam, install the door hanger 13 at the installation position 11 of the front beam, match the driving with the door hanger 13, lift the front beam, and install it on the door hanger by adjusting Two pulley slings 1301 on the 13 make the front beam erect. Specifically, it includes shortening one of the pulley slings 1301 and extending the other pulley sling 1301 .

[0050] d2, place the mobile platform 7 at the starting point again, pull the rear beam to the installation position 12 of the rear beam, lift the rear beam with a jack, remove the mobile platform 7, the rolling steel pipe 8, the fixed platform 4, the reinforcing column 5 and the connection Column 6.

[0051] d3, set up the first temporary pillar to support the front beam, and cooperate with the jack to gradually lower the height of the front beam until the front beam is in pla...

Embodiment 2

[0052] Embodiment two, said step D, comprises the following steps:

[0053] d1, pull the front beam to the installation position 11 of the front beam, install the door hanger 13 at the installation position 11 of the front beam, match the crane with the door hanger 13, and remove the mobile platform 7 and the rolling steel pipe 8 after lifting the front beam , dismantling section 402 and connecting column 6; By adjusting two pulley slings 1301 installed on the portal hanger 13, the front cross beam is erected; the first temporary pillar is set up to support the front cross beam, and the height of the front cross beam is lowered successively with the jack, Until the front beam is in place.

[0054] Correspondingly, this part of the fixed platform 4 between the front beam installation position 11 and the rear beam installation position 12 is the dismounting section 402; The two pulley slings 1301 of the portal hanger 13 are located above the front beam installation position 11 ...

Abstract

The invention discloses a method for installing a front beam and a rear beam of an extruder with a short construction period and a simple structure, comprising the following steps: A, installing a reinforced steel column in a basement located on one side of a concrete foundation; , Install a reinforced column between the fixed platform and the basement roof, and the reinforced column and the reinforced steel column are arranged coaxially; install the connecting column between the fixed platform and the concrete foundation; install the mobile platform and several rolling steel pipes on the fixed platform from top to bottom Above; C, connect the first towing hook and the second towing hook through the chain block; the length direction of the rolling steel pipe is perpendicular to the pulling direction of the chain block; D, the front beam and the rear beam placed on the mobile platform , through the hand chain hoist to move from the starting point to the installation end, until it is pulled to the respective installation position, to be in place. It is easy to make, easy to operate, low in construction cost, simplifies the installation process of the front crossbeam and the rear crossbeam of the extrusion machine in a restricted environment, and has little safety risk.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment installation, in particular to a method for installing a front beam and a rear beam of an extrusion machine. Background technique [0002] Metal extrusion machine, hereinafter referred to as: extrusion machine, usually installed on the concrete foundation, is the most important equipment to realize metal extrusion processing, and is to process metal ingots into tubes, rods, profiles, etc. at one time. The extrusion machine is mainly composed of three major parts: mechanical part, hydraulic part and electrical part. Among them, the mechanical part is composed of base, prestressed frame type tension column, front beam, movable beam, rear beam, extrusion shaft, ingot feeding mechanism, residual material separation shear and sliding mold base, etc. [0003] Due to the mass and volume of the extruder, auxiliary equipment is usually required during the installation of the extruder. In the...
