Description

Monorail type self moving gantry crane

The present invention relates to a monorail self-supporting mobile gantry crane. More specifically, the components of the gantry crane are modularized and easy to assemble and dismantle by coupling structures such as bolts, nuts, pins and hinges between modules, and girder piers and girders are integrally joined in a U-shape to form gantry cranes. It is possible to move without damage to the mounted state without disassembling the hoist installed on the girder rail when moving the vehicle, etc.The combination of the main piers and the auxiliary piers is used to adjust the height of the lift and to lift the head height deviation between the left and right pairs of the main piers and the running rails. It is possible to calibrate, adjust the length of the girder by changing the connecting bar, supply the products certified for safety certification, and easily install and use it without the need for a separate H beam pillar in the apartment-type factory. When it is used, it is less influenced by wind load, so it can be widely applied in coastal zone and bridge construction work. And a monorail self-supporting gantry crane.

In general, the gantry crane is a mandatory safety certification product as a dangerous machine, and thus requires written and product review. When the gantry crane is installed, the running rail is firmly fixed by inserting or exposing the foundation rail to concrete. In addition, it is not easy to change the height of the head height or the girder width after the appearance is determined according to the design dimensions. There is a hassle to get back and get approval.

In addition, even when the installation location of the gantry crane has been transferred, there is a problem in use if it is necessary to change the relationship to obtain re-approval.

Most of the gantry cranes that are generally used in factory or outside construction are composed of one-piece type, so it is not easy to install and dismantle. In addition, when moving the gantry crane using a vehicle, dismantling and moving work is very cumbersome since the hoist installed on the girder rail must be dismantled.

In addition, the general gantry crane has a fixed height and the width of the front, rear, left and right, and as mentioned above, if there is a need to change the specifications, there is an inconvenience to obtain a re-examination and re-approval through a separate design.

Therefore, the installation and dismantling of gantry cranes and the change of specifications are free, and the hoist installed on the girder rail can be easily transported by separating each module without disassembling, and it is easy to combine and separate the bridge and the girder. Therefore, there is a need to develop a gantry crane that can be used to adjust the length of the girder by changing the height of the upper and lower cranes and the connecting bar considering the wind load in outdoor use.

The present invention has been made to solve the above problems, in particular, easy to assemble and dismantle, can move without damage to the mounted state without disassembling the hoist installed on the girder rail when moving the gantry crane, head height considering the outdoor wind load The purpose is to provide a monorail self-contained gantry crane that can adjust the height difference between the left and right pairs of main piers and the running rails, and can supply products certified for safety certification.

Monorail type self-supporting gantry crane according to the present invention devised to achieve the above object is a pair of running rails (1A, 1B) disposed parallel to the base floor; Driving driving units (2A, 2B, 2C, 2D) moving on the traveling rail unit; Main piers 3A, 3B, 3C, and 3D that are detachably coupled to an upper end of the driving unit; Girder piers (6A, 6B, 6C, 6D) detachably coupled to an upper end of the main pier; A girder including girder (7A, 7B) forming the girder pier and the girder bridge; A trust connection bar (8A, 8B) detachably coupled between the girder piers; A lift beam 11 coupled to the bottom of the girder; First connection bars 4A and 4B having left and right pairs of left and right pairs of main bridges 3A, 3B, 3C, and 3D coupled to each other by hinge-type pin fastenings; Second connecting bars 9A, 9B, and 9C having left and right girder pairs coupled to each other by bolting to each other; Third connection bars 10A and 10B coupled in a diagonal direction between the second connection bar and the girder; An auxiliary piers 12A and 12B inserted between the main piers and the girder piers to adjust head heights and to correct head height deviations between the left and right pairs of main piers and the running rails 1A and 1B; It characterized in that the cantilevered jib-type hoist (5) is rotatably coupled to at least one of the main piers.
