Abstract
The utility model discloses a crane girder positioning device which is characterized by comprising a girder connection plate and an end beam connection plate, wherein the girder connection plate is connected with a girder through a bolt group; the end beam connection plate is connected with an end beam through a bolt group; a positioning hole is formed in the girder connection plate; and a positioning sleeve matched with the positioning hole is welded on the end beam connection plate. According to the crane girder positioning device, the shortcoming of positioning by the conventional elastic pin is overcome; and the crane girder positioning device can position the girder accurately and is reliable in positioning quality.
Description
Technical field
The utility model relates to a kind of crane in bridge type, especially a kind of crane girder registration device.
Background technology
Crane in bridge type is important tool and an 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 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 made up of crane carriage, crane span structure operating unit, crane span structure metal construction.Crane carriage is made up of lifting mechanism, wheeling mechanism and trolley frame three parts again.The metal construction 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 classes.Single girder crane span structure is made up of single girder and the end carriage that is positioned at the span both sides, and double girder bridge is made up of two girders and end carriage.Conventional hoisting crane adopts bolt and bearing pin location, because the easily deformable inaccurate and knock hole align reaming difficulty in location that causes of elasticity bearing pin.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.
The utility model content
The utility model purpose is: a kind of simple in structure, accurate positioning, reliable quality crane girder registration device are provided.
The technical solution of the utility model is: a kind of crane girder registration device is characterized in that 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.
The utility model installation steps are as follows:
(1) with the bolt group end carriage and end carriage connecting panel are fixed and are placed on the assembling moulding bed of adjusting;
(2) with the bolt group girder and girder connecting panel are fixed;
(3) adjust two end carriage relative positions, on connecting panel, make girder connecting panel and end carriage connecting panel fit main cable and girder;
(4) adjust the position of girder on end carriage on request, 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, the position of girder and end carriage is checked in the welding back, after meeting the requirements locating bush and end carriage connecting panel is welded.
Further, also comprise following installation steps: push down locating bush with gland in locating bush and end carriage connecting panel welding back and gland is fixed on the girder connecting panel with bolt.
The utility model has the advantages that:
Overcome the shortcoming of original resilient pin location, accurate positioning, reliable in quality.

The specific embodiment
Embodiment: as Fig. 1, Fig. 2, crane girder registration device shown in Figure 3, comprise girder connecting panel 3 and end carriage connecting panel 4, girder connecting panel 3 links to each other 1 by tie bolt group 8 with girder; End carriage connecting panel 4 links to each other with end carriage 2 by the bolt group; The girder connecting panel is provided with knock hole, is welded with the locating bush 7 with described knock hole coupling on the end carriage connecting panel.Also be provided with gland 6 on the girder connecting panel 3, gland 6 links to each other with girder connecting panel 3 by dog bolt group 5.Locating bush in the present embodiment is cylindrical, can also be truncated cone-shaped.Installation steps are as follows:
(1) with the bolt group end carriage and end carriage connecting panel are fixed and are placed on the assembling moulding bed of adjusting;
(2) with the bolt group girder and girder connecting panel are fixed;
(3) adjust two end carriage relative positions, on connecting panel, make girder connecting panel and end carriage connecting panel fit main cable and girder;
(4) adjust the position of girder on end carriage on request, 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, the position of girder and end carriage is checked in the welding back, with the welding of locating bush and end carriage connecting panel, afterwards push down locating bush and gland is fixed on the girder connecting panel after meeting the requirements with bolt with gland in locating bush and the welding of end carriage connecting panel.
Adopted crane girder registration device of the present utility model to overcome the shortcoming that original resilient pin is located, accurate positioning, reliable in quality.
The above only is the specific embodiment of utility model.Protection domain of the present utility model is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
