Abstract
The utility model discloses a connecting structure between a trolley frame and a connecting bridge. The utility model aims to provide a connecting structure between a trolley frame and a connecting bridge, which ensures that the wheel of a trolley can not secede from the track. The utility model adopts the technical proposal that the connecting structure between the trolley frame and the connecting bridge comprises a trolley. The trolley frame on one side of the trolley is fixedly connected with one end of the connecting bridge, and the trolley frame on the other side of the trolley is hinged with the other end of the connecting bridge. The utility model has the technical effects that because two wheels on the trolley frame hinged with the connecting bridge together can automatically be adjusted through a hinge shaft to ensure that the two wheels can be in contact with the track always, the vertical disengage phenomena of the wheel and the trolley frame can be effectively prevented. The utility model is mainly used for cranes.
Description
Technical field
The utility model relates to the connection structure between the connection structure on the hoisting crane, particularly car frame and connecting bridge.
Background technology
Two vehicle frames of the dolly of existing hoisting crane are captive joint with being connected of connecting bridge two ends, sometimes because of dolly wheel movement track injustice, perhaps four wheels of dolly are when a plane, have in orbit at dolly the phenomenon that wheel and track break away from up and down to occur.
Summary of the invention
The technical matters that the utility model solves provides a kind of dolly that makes and can not occur the car frame of wheel and track break-off and the connection structure between connecting bridge in orbit.Technical solutions of the utility model are finished like this, connection structure between car frame and connecting bridge, include dolly, the vehicle frame of dolly one side and an end of connecting bridge are fixed together, and it is characterized in that: the vehicle frame of dolly opposite side and the other end of connecting bridge are hinged together.Technique effect of the present utility model is: because of two wheels on the vehicle frame that is hinged together with connecting bridge, can regulate voluntarily by articulated axle and keep two wheels to contact with track all the time, can effectively prevent the phenomenon that wheel and track break away from up and down.
Description of drawings
Fig. 1 is a front view of the present utility model; Fig. 2 is a side cutaway view of the present utility model; Fig. 3 is the utility model birds-eye view.
Drawing explanation: 1, bolt; 2, groove; 3, left wallboard; 4, vehicle frame; 5, catch; 6, gap; 7, brace panel; 8, articulated axle; 9, right wallboard; 10; Connecting bridge.
The specific embodiment
In conjunction with the accompanying drawings the utility model is further described an end weld together of the vehicle frame of dolly one side and connecting bridge 10; As shown in Figure 2, all have the axis hole that matches with articulated axle 8 on dolly opposite side vehicle frame 4, left wallboard 3, the right wallboard 9, the left end of articulated axle 8 has a groove 2, groove 2 cooperates articulated axle 8 fixing with catch 5 be fixed on left wallboard 3 with carriage bolt on, prevent that articulated axle 8 from coming off, all there is brace panel 7 at the axis hole place of the inboard of vehicle frame 4, and vehicle frame 4 upper ends and connecting bridge 10 corresponding parts leave gap 6; The left wallboard 3 and the right wallboard 9 of connecting bridge end are welded on the connecting bridge.Fixedly articulated axle and catch are fixed on structure on the wallboard of left side obviously to find out catch from Fig. 1, Fig. 3.
