Description
Technical field
The utility model belongs to technical field of crane equipment, is specifically related to that a kind of structure is simple, the hinged trolley frame of the hoisting crane that can adapt to orbit of working stability.
Background technology
The trolley frame of conventional hoist is generally made up of two longerons and a crossbeam, wherein longeron links together by bolt group or with the mode of welding and the crossbeam at two ends, this connection mode of trolley frame makes longeron and crossbeam when assembly and connection, be not easy to regulate its coordinating with hoisting crane, as long as longeron and crossbeam have a very little relative rotation, or the both ends of the surface that the torsional deflection of longeron makes longeron be connected with crossbeam are not at grade, or the welding deformation of crossbeam axletree hole machined positional error and crossbeam, wheel diameter Mismachining tolerance, the reasons such as track installation error, four wheels of monkey will be caused not in one plane, dolly occurs only having three wheel supportings to touch orbit, so not only accelerate wheel rim wearing and tearing, and wheel rim can occur climb rail and wheel derailment accident.Simultaneously, if when the operation driver train of dolly is for driving respectively, lift once there is adhesion wheel, there is monolateral driving phenomenon, the propulsive effort of wheel and running resistance will form horizontal additional force couple, produce lateral pressure and additional resistance, cause drive motor load excessive, running velocity is slowed down or does not run.Therefore research and develop a kind of hinged trolley frame of hoisting crane that can adapt to orbit to be very important.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, the hinged trolley frame of the hoisting crane that can adapt to orbit of working stability.
The purpose of this utility model realizes like this, comprise longeron, crossbeam and tie bolt, described longeron two ends vertically arrange crossbeam, be fastenedly connected by tie bolt between longeron and crossbeam, described longeron at least one end arranges jointed shaft and rotates with crossbeam and connect, and the end winding support of described longeron arranges end plate, and the centre hole of described end plate blocks the chuck of jointed shaft one end, the other end of described jointed shaft extends through the vertical through hole that crossbeam is arranged, and arranges fixing back-up ring on the periphery of end.
Longeron is connected by jointed shaft with crossbeam by the utility model, make when trolley frame has manufacture assembly error or parallel track degree is good not, trolley frame can adapt to track automatically, dolly four wheels is all run in orbit, avoid wheel wear uneven, Moment is different and produce the situation that lateral pressure even derails, the end plate top that the end of longeron is arranged arranges horizontal seam to be had to a certain extent and prevents crossbeam in the excessive effect of vertical direction amplitude of fluctuation, make trolley frame working stability, the utility model structure is simple, working stability, avoid because dolly and track can not fit like a glove work and the problems caused.

In figure: 1-longeron, 11-end plate, the horizontal seam of 111-, 2-crossbeam, 3-transition backing plate, 4-fixes back-up ring, 5-caging bolt, 6-jointed shaft, 7-tie bolt.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but must not be limited the utility model by any way, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As shown in accompanying drawing 1 ~ 3, the utility model comprises longeron 1, crossbeam 2 and tie bolt 7, described longeron 1 two ends vertically arrange crossbeam 2, be fastenedly connected by tie bolt 7 between longeron 1 and crossbeam 2, described longeron 1 at least one end arranges jointed shaft 6 and rotates with crossbeam 2 and connect, the end winding support of described longeron 1 arranges end plate 11, the centre hole of described end plate 11 blocks the chuck of jointed shaft 6 one end, the other end of described jointed shaft 6 extends through the vertical through hole that crossbeam 2 is arranged, and on the periphery of end, arrange fixing back-up ring 4.
Described crossbeam 2 is fixedly installed transition backing plate 3 with end plate 11 junction, and described jointed shaft 6 is successively through end plate 11, transition backing plate 3 and crossbeam 2.
Described fixing back-up ring 4 arranged outside caging bolt 5, described caging bolt 5 is vertically installed in the outer round surface of jointed shaft 6.
Described jointed shaft 6 is hollow shaft, and hollow shaft arranges closing plate 61 near one end of longeron 1.
The stage casing cross-sectional area of described longeron 1 is greater than the cross-sectional area at two ends.
Described caging bolt 5 evenly arranges 6 ~ 8 along the outside face of jointed shaft 6, and near fixing back-up ring 4.
The endoporus of the endoporus of described fixing back-up ring 4, the vertical through hole of crossbeam 2 and transition backing plate 3 all with jointed shaft 6 free-running fit.
Described jointed shaft 6 is fixedly connected with end plate 11, with crossbeam 2 normal-running fit.
Described jointed shaft 6 and end plate 11 normal-running fit, be fixedly connected with crossbeam 2.
