The invention discloses a crane main beam positioning device which is characterized by comprising a main beam connecting board and an end beam connecting board; the main beam connecting board is connected with a main beam through a bolt group; the end beam connecting board is connected with an end beam through a bolt group; a positioning hole is formed in the main beam connecting board; and a positioning sleeve matched with the positioning hole is welded on the end beam connecting board. The crane main beam positioning device overcomes the defects of positioning of the original elastic pin, is accurate in positioning and has a reliable quality.
Description
Technical field
The present invention relates to a kind of crane in bridge type, especially a kind of crane girder registration device and method.
Background technology
Crane in bridge type is important tool and the equipment of realizing production process mechanization, automation in modern industry production and the lifting transportation.So crane in bridge type is all used widely in the departments such as indoor and outdoor industrial and mining enterprises, steel chemical, railway traffic, port and pier and logistics turnover and place.Ordinary bridge crane generally is comprised of crane carriage, crane span structure operating unit, crane span structure metal construction.Crane carriage is comprised of lifting mechanism, wheeling mechanism and trolley frame three parts again.The metal construction of crane span structure is comprised of girder and end carriage, is divided into single girder crane span structure and double girder bridge two classes.Single girder crane span structure is comprised of single girder and the end carriage that is positioned at the span both sides, and double girder bridge is comprised of two girders and end carriage.Conventional hoisting crane adopts bolt and bearing pin location, because easily deformable the causing of elasticity bearing pin located inaccurate and knock hole align reaming difficulty.Resilient pin is easy to come off after using a period of time, causes girder to produce displacement with respect to end carriage, causes hoisting crane to gnaw rail.
Summary of the invention
The present invention seeks to: crane girder registration device and method that a kind of simple in structure, accurate positioning, reliable in quality are provided.
Technical scheme of the present invention is: a kind of crane girder registration device, it is characterized in that, and comprise girder connecting panel and end carriage connecting panel, described girder connecting panel links to each other with girder by the bolt group; Described end carriage connecting panel links to each other with end carriage by the bolt group; Described girder connecting panel is provided with knock hole, is welded with the locating bush with described knock hole coupling on the described end carriage connecting panel.
Further, also be provided with gland on the described girder connecting panel, described gland links to each other with the girder connecting panel by bolt.
Further, described locating bush is cylindrical.
A kind of crane girder localization method is characterized in that, may further comprise the steps:
(1) with the bolt group end carriage and end carriage connecting panel are fixed and are placed on the assembling jig frame of adjusting;
(2) with the bolt group girder and girder connecting panel are fixed;
(3) adjust two end carriage relative positions, with main cable and girder on connecting panel, so that girder connecting panel and end carriage connecting panel fit;
(4) adjust on request the position of girder on end carriage, locating bush is loaded to the locating bush end face and end carriage connecting panel upper surface fits from the knock hole on the girder connecting panel;
(5) spot welding locating bush and end carriage connecting panel;
(6) with girder and the welding of girder connecting panel, check the position of girder and end carriage after the welding, after meeting the requirements locating bush and end carriage connecting panel are welded.
Further, further comprising the steps of: as after the welding of locating bush and end carriage connecting panel, to push down locating bush with gland and with bolt gland is fixed on the girder connecting panel.
Advantage of the present invention is:
Overcome the shortcoming of original resilient pin location, accurate positioning, reliable in quality.
