Abstract
The utility model relates to a Bailey truss combined gantry crane which comprises a portal frame, an overhead crane and a wheel component fixed on the bottom side of the portal frame. The portal frame consists of a left supporting leg and a right supporting leg which are arranged vertically, as well as a main beam crossing the left supporting leg and the right supporting leg. The combined gantry crane is characterized in that the left supporting leg, the right supporting leg and the main beam are formed by combining a plurality of rows of trusses; each row of truss consists of a plurality of truss units which are superposed; the adjacent truss units are positioned and connected by a bolt; and the lateral surfaces of the trusses in the left supporting leg, the right supporting leg and the main beam are fixedly connected through a support frame. The utility model has the advantages of flexible maneuver, convenient assembly and disassembly, simple structure, low cost, multiple functions and reuse, and uniform stress of each row of trusses in the mean beam of the crane.
Description
[technical field]
The utility model relates to a kind of Bailey truss combination transfer crane.
[background technology]
Fast development along with China's economic construction, highway in China, railway, urban construction are in a high-speed developing period, Bailey truss combination transfer crane plays effects such as handling, erecting concrete T-shaped beam, case beam in highway building sites such as building highway, inter-city rail transit, city height, be subjected to users' welcome deeply.
Yet the truss of existing Bailey truss combination transfer crane mostly is single design, makes its hoisting capacity mostly below 100 tons, is difficult to bear large-tonnage handling work.Along with transport vehicle develops towards maximization, heavy-duty, super-huge bridge continues to bring out, and needs more large-tonnage heavy lift of hoisting capacity.
Therefore, the utility model is done further to improve to Bailey truss combination transfer crane at above-mentioned prior art deficiency.
[summary of the invention]
The purpose of this utility model provides big, simple in structure, the stressed uniform Bailey truss combination transfer crane of a kind of hoisting capacity.
At above-mentioned purpose, the utility model by the following technical solutions:
Bailey truss combination transfer crane includes portal frame, overhead traveling crane and is fixed on the vehicle wheel component of portal frame bottom side; Described portal frame is by the left and right supporting leg of vertical setting and across forming at the girder of left and right supporting leg upper end, it is characterized in that described left and right supporting leg and girder are to be combined by many rows truss, and every row's truss is to be made of a plurality of truss element stacks, uses latch to be located by connecting between the described truss element two ends of facing mutually; Wherein, described left and right supporting leg is captiveed joint by bracing frame with the many rows truss side in the girder.
Aforesaid Bailey truss combination transfer crane, the upper end that it is characterized in that described many row's truss is provided with and makes it stressed uniform crossbeam, and described crossbeam is provided with guide rail, and described overhead traveling crane is arranged on the guide rail of crossbeam.
Aforesaid Bailey truss combination transfer crane is characterized in that being provided with between described left and right supporting leg upper end and the girder and holds spider and captive joint.
Aforesaid Bailey truss combination transfer crane is characterized in that described girder is a twin-spar construction, and the row's number that constitutes the truss of single-beam in left and right supporting leg and the girder is 3～5 rows.
The beneficial effects of the utility model are: 1, have maneuverability, easy accessibility, simple in structure, cheap, diverse in function, characteristics such as reusable; 2, respectively to arrange truss stressed evenly for the girder of hoisting crane.
[description of drawings]
The utility model will be further described below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a scheme drawing of the present utility model;
Fig. 2 is the utility model portal frame scheme drawing;
Fig. 3 is for facing the connection structure scheme drawing between the truss element mutually.
[specific embodiment]
As shown in the figure, Bailey truss combination transfer crane includes portal frame 1, overhead traveling crane 2 and is fixed on the vehicle wheel component 3 of portal frame 1 bottom side.Described portal frame 1 is by the left and right supporting leg 4 of vertical setting and across forming at the girder 5 of left and right supporting leg 4 upper ends.Described left and right supporting leg 4 and girder 5 are to be combined by many rows truss 6, and every row's truss 6 is to be made of 60 stacks of a plurality of truss elements, use latch 10 to be located by connecting between the described truss element that faces mutually 60 two ends; Wherein, described left and right supporting leg 4 is captiveed joint by bracing frame 7 with many rows truss 6 sides in the girder 5.Make many row's truss 6 form a common stressed integral body, the load-carrying ability of described portal frame 1 strengthens greatly, thereby can sling more large-tonnage article, is convenient to the assembling and the dismounting of portal frame 1 simultaneously.
In the present embodiment, be provided with in described girder 5 upper ends and make it stressed uniform crossbeam 8, described crossbeam 8 is provided with guide rail 80, and overhead traveling crane 2 is arranged on the guide rail 80 of crossbeam 8, make between every row's truss stressed evenly.
Be provided with between the two ends of the upper end of described left and right supporting leg 4 and girder 5 and hold spider 9 and captive joint, make left and right supporting leg 4 more firm.
For the lifting tonnage that makes this product surpasses 100 tons or gross ton position more, described girder 5 be a twin-spar construction, and the row's number that constitutes the truss 6 of single-beam in left and right supporting leg 4 and the girder 5 is made as 3～5 and arranges.
The utility model because of left and right supporting leg 4 and the girder 5 that constitutes portal frame 1 all is set as the combination of many row's truss, the lifting tonnage of hoisting crane is increased greatly, and cost is relatively low in use, and therefore, market outlook can be better.
