Abstract
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 bridge crane, especially a kind of crane girder positioner and method.
Background technology
bridge crane be modern industry produce and lifting transport in realize production process mechanization, the important tool of automation and equipment.So bridge crane is used all 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 is generally made up of trolley, crane span structure travelling mechanism, crane span structure metal structure.Trolley again by lifting mechanism, wheeling mechanism and trolley frame three part form.The metal structure of crane span structure is made up of girder and end carriage, is divided into single girder crane span structure and double girder bridge two class.Single girder crane span structure is made up of single girder and the end carriage being positioned at span both sides, and double girder bridge is made up of two girders and end carriage.Conventional crane employing bolt and bearing pin location, cause location inaccurate because elastic pin shaft is easily deformable and locating hole align reaming is difficult.After using a period of time, resilient key is easy to come off, and causes girder to produce displacement relative to end carriage, causes crane to gnaw rail.
Summary of the invention
the present invention seeks to: provide that a kind of structure is simple, accurate positioning, the crane girder positioner of reliable in quality and method.
technical scheme of the present invention is: a kind of crane girder positioner, is characterized in that, comprises girder connecting plate and end carriage connecting plate, and described girder connecting plate is connected with girder by bolt group; Described end carriage connecting plate is connected with end carriage by bolt group; Described girder connecting plate is provided with locating hole, described end carriage connecting plate is welded with the positioning sleeve mated with described locating hole.
further, described girder connecting plate is also provided with gland, and described gland is connected with girder connecting plate by bolt.
further, described positioning sleeve is cylindrical.
a kind of crane girder localization method, is characterized in that, comprise the following steps:
(1) by bolt group end carriage and end carriage connecting plate fixed and be placed on the assembling jig frame adjusted;
(2) by bolt group, girder and girder connecting plate are fixed;
(3) adjust two end carriage relative positions, by main cable and girder on connecting plate, girder connecting plate and end carriage connecting plate are fitted;
(4) adjust the position of girder on end carriage on request, positioning sleeve is loaded to positioning sleeve end face from the locating hole girder connecting plate and end carriage connecting plate upper surface fits;
(5) spot welding positioning sleeve and end carriage connecting plate;
(6) girder is welded with girder connecting plate, check the position of girder and end carriage after welding, after meeting the requirements, positioning sleeve is welded with end carriage connecting plate.
further, further comprising the steps of: after positioning sleeve welds with end carriage connecting plate, to push down positioning sleeve with gland and with bolt, gland is fixed on girder connecting plate.
advantage of the present invention is:
overcome the shortcoming of original resilient key location, accurate positioning, reliable in quality.

(2) by bolt group, girder and girder connecting plate are fixed;
(3) adjust two end carriage relative positions, by main cable and girder on connecting plate, girder connecting plate and end carriage connecting plate are fitted;
(4) adjust the position of girder on end carriage on request, positioning sleeve is loaded to positioning sleeve end face from the locating hole girder connecting plate and end carriage connecting plate upper surface fits;
(5) spot welding positioning sleeve and end carriage connecting plate;
(6) girder is welded with girder connecting plate, the position of girder and end carriage is checked after welding, after meeting the requirements, positioning sleeve is welded with end carriage connecting plate, after positioning sleeve welds with end carriage connecting plate, push down positioning sleeve with gland and with bolt, gland is fixed on girder connecting plate.
have employed the shortcoming that crane girder positioner of the present invention overcomes original resilient key location, accurate positioning, reliable in quality.
the above, be only the detailed description of the invention of invention.Protection scope of the present invention is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention discloses, the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
