Preferably, in above-mentioned trolley frame, described head pulley crossbeam is overlapped on above described end carriage.
Preferably, in above-mentioned trolley frame, described crossbeam is connected with described end carriage bolt.
Preferably, in above-mentioned trolley frame, described crossbeam is docked on the web of described end carriage.
Preferably, in above-mentioned trolley frame, described trolley frame platform is connected with described transom bolt.
Preferably, in above-mentioned trolley frame, described trolley frame platform is arranged on the bottom surface of described crossbeam.
With respect to prior art, technique effect of the present utility model is:
The trolley frame that the utility model provides comprises end carriage, crossbeam, trolley frame platform and head pulley crossbeam; Crossbeam, trolley frame platform and head pulley crossbeam all are arranged between two end carriages, and the head pulley crossbeam is connected with the end carriage bolt.
As can be known, because head pulley crossbeam and end carriage in the utility model are with bolts, be welded to connect than of the prior art, avoided in the welding process impact of end carriage machining dimension is made the installation process accurate positioning; On the other hand, removably connect because bolt is connected to, therefore, in transportation, can dismantle comes carries out respectively, is convenient to transportation.
The invention also discloses a kind of hoisting crane, comprise the hoisting crane body and be arranged on trolley frame on described hoisting crane body, described trolley frame is above-mentioned trolley frame.Because above-mentioned trolley frame has above-mentioned technique effect, the hoisting crane with above-mentioned trolley frame also should have identical technique effect.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to the accompanying drawing that provides other accompanying drawing.
The birds-eye view of the trolley frame that Fig. 1 provides for the utility model embodiment;
The front view of the trolley frame that Fig. 2 provides for the utility model embodiment;
The lateral plan of the trolley frame that Fig. 3 provides for the utility model embodiment.
In upper figure, the corresponding relation between Reference numeral and component names is:
1 end carriage; 2 crossbeams; 3 trolley frame platforms; 4 head pulley crossbeams.
The specific embodiment
Core of the present utility model is to provide a kind of trolley frame, can guarantee that the machining dimension of installation process end carriage is unaffected, makes the installation process accurate positioning, is convenient to simultaneously transportation.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.Obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the birds-eye view of the trolley frame that Fig. 1 provides for the utility model embodiment; The front view of the trolley frame that Fig. 2 provides for the utility model embodiment; The lateral plan of the trolley frame that Fig. 3 provides for the utility model embodiment.
As shown above, the trolley frame that the utility model embodiment provides comprises end carriage 1, crossbeam 2, trolley frame platform 3 and head pulley crossbeam 4; Crossbeam 2, trolley frame platform 3 and head pulley crossbeam 4 all are arranged between two end carriages 1, and head pulley crossbeam 4 is connected with end carriage 1 bolt.
As can be known, because head pulley crossbeam in the utility model 4 and end carriage 1 are with bolts, be welded to connect than of the prior art, avoided in the welding process impact of end carriage 1 machining dimension is made the installation process accurate positioning; On the other hand, removably connect because bolt is connected to, therefore, in transportation, can dismantle comes carries out respectively, is convenient to transportation.
Further, in the utility model, above-mentioned head pulley crossbeam 4 is overlapped on the top of end carriage 1.Because head pulley crossbeam 4 bearing capacities are larger, it is overlapped on end carriage 1 top, be conducive to integral body stressed of trolley frame.
In order further to optimize above-mentioned technique effect, in the trolley frame that the utility model provides, above-mentioned crossbeam 2 is also with bolts with end carriage 1, has further avoided in the welding process the impact of end carriage 1 machining dimension, makes the installation process location more accurate; On the other hand, removably connect because bolt is connected to, therefore, in transportation, can dismantle comes carries out respectively, more is convenient to transportation.
