The specific embodiment

As shown in Figure 1, oil well heavy repair task machine is made up of driver's cabin 1, motor 2, chassis frame 3, transmission system 4, rig floor 5, derrick 6, water tap 7, hook block 8, guy wire 9, chassis frame 3 comprises crossbeam body 10, middle back axle equalizer bar suspension 11, propons equalizer bar suspension 12, propons 13, jackshaft 14, back axle 15, as Fig. 2, shown in Figure 3.Crossbeam body 10 is an integral frame that is welded by two box longerons and some crossbeams, cut section bar with I-shaped and to compare, the box-type section beam has better intensity and rigidity, and for some relatively more bumpy road surfaces, oil field, the box-type section beam more can be resisted the bending and the torsional deformation of vehicle frame.

Middle back axle equalizer bar suspension 11 comprises bearing 20, back axle 15, jackshaft 14, axle 22, longitudinal balance beam 23, axis 25, middle bearing 26, ramuscule seat 27a, ramuscule seat 27b, little axle 28a, little axle 28b, pull bar 29 and big support 30, big support 30 is welded as a whole with crossbeam body 10, middle bearing 26 is welded on the big support 30, equalizer bar 23 links to each other with middle bearing 26 by axis 25, stud with copper sheathing 32 between axis 25 and the middle bearing 26, longitudinal balance beam 23 two ends link to each other with bearing 20 by axle 22, four bearings 20 are welded on jackshaft 14 respectively, bottom, back axle 15 two ends, between axle 22 and the bearing 20 oscillating bearing 31 is arranged, pull bar 29 two ends are by little axle 28a, 28b is connected to ramuscule seat 27a, on the 27b, ramuscule seat 27a, 27b is welded on respectively on bridge and the big support 30, as Fig. 4, shown in Figure 5, middle back axle equalizer bar suspension frame structure vertical and horizontal all can be swung, even four tires of back axle also can support on the ground uniformly at uneven road surface in can making, avoid the over-tilting and the distortion of vehicle frame, thereby safety and stationarity that main car travels have been guaranteed, pull bar 29 is excessive for back axle amplitude of fluctuation in preventing, avoids plane and vehicle frame lower plane generation collision on the middle back axle.
