The specific embodiment
Come preferred implementation of the present utility model is described with reference to appended accompanying drawing below.Should be understood that embodiment disclosed herein only is a preferred version of the present invention, except the disclosed mode, the utility model can also be realized with various other forms.
The perspective view that dolly is installed according to the undercarriage of the utility model preferred implementation has been shown among Fig. 1-4.As shown in the figure, undercarriage installation dolly 100 comprises underframe 20, vertical rack 30, bracing frame 40, hydraulic loading system 50, bottom surface adjusting device 60, pull bar 70 and anchor ear 80.
Wherein, the chassis of the whole dolly of underframe 20 formation is used for dolly is moved to the fuselage below of being with the installation undercarriage, and supports dolly integral body and the undercarriage that is fixed on the dolly.It comprises bottom girder 21, cross bar 22 (shown in clear more among Fig. 3), front-wheel 23 and paired trailing wheel 24.Wherein, bottom girder 21 and cross bar 22 all have very high rigidity and hardness, for example make with steel pipe, and intersect and to become " ten " word, thereby the support of more stable and stronger is provided for dolly.Two ends, the left and right sides at the front end and the cross bar 22 of bottom girder 21 are separately installed with front-wheel 23 and paired trailing wheel 24, are used to realize that the convenience of dolly moves.
Alternatively, the intensity of front-wheel 23 can be higher than trailing wheel 24 because front-wheel 23 is except being used for the travelling car as trailing wheel 24, also will be when determining that undercarriage is installed the support bottom surface of dolly, obtain more clearly illustrating during this will be described below.
Bottom surface adjusting device 60 also is installed on underframe 20, is used to regulate the bottom supporting face that dolly 100 is installed, and is implemented in the installation process of whole undercarriage, dolly can remain stable and can not move and tilt.In the present embodiment, a pair of symmetrically arranged bottom surface adjusting device 60 has been installed on underframe 20, shown in clear more among Fig. 3, they lay respectively at the left and right sides of bottom girder 21, and are fixed on the cross bar 22.
Specifically, each bottom surface adjusting device 60 includes leg 61, threaded sleeve 62, threaded rod 64 and handle 63.Wherein, threaded sleeve 62 is fixed on the cross bar 22 by modes such as screws, and its screw thread extends along vertical direction.Threaded rod 64 can cooperate with threaded sleeve 62, and can move up and down in threaded sleeve 62 by rotation.Leg 61 is installed in the bottom of threaded rod 64, and its bottom has supporting surface, is used for contacting with ground in installation process, thereby dolly and the undercarriage that is fixed on the dolly are supported on the ground.And the top of the threaded rod 64 horizontally extending handle 63 of can packing into is operated for operating personnel, thereby realizes that easily dolly supports the adjusting of bottom surface.
And except two bottom surface adjusting devices 60, front-wheel 23 is also as a fulcrum that supports the bottom surface.Owing to can determine any one plane at 3, so the support bottom surface of dolly can be set fully freely basically.
Alternatively, two braces 32 by under the position, a beam 33 can be installed between two braces again, thereby form the roughly structure of " A " shape.Such setting is except the stability of further raising vertical rack 30, and beam 33 can also be used for other purposes, and this will describe in subsequent descriptions.Further alternatively, can also link to each other with underframe 20 with the middle part of connecting rod with this beam 33, this also is the effective ways that improve the fastness that connects between the stability of vertical rack 30 and underframe 20 and the vertical rack 30.
Include bracing frame 40 on the top of vertical rack 30, the bogey when it is installed as undercarriage.Specifically, bracing frame 40 comprised longitudinal beam 41, and it presents tubular structure, and the straight-bar 31 of an end and vertical rack 30 is hinged, and the other end is socketed with an installation in the tubular structure that can be plugged on longitudinal beam 41 42.In addition, install 42 with the motion of the longitudinal beam 41 of bracing frame 40 by the pin restrictive axial, install 42 rotatable in certain scope.This installation 42 can form roughly forked structure, comprises the jaws 43 that two biasings are from the side extended.Wherein, longitudinal beam 41 also can be made by steel pipe, also presents columniform cross section and 42 rear end is installed, and its external diameter is slightly less than the internal diameter of longitudinal beam 41, fixes thereby can be sleeved on together and by fixture.And why that longitudinal beam 41 and straight-bar 31 is hinged, be for make install 42 along with longitudinal beam 41 together with respect to straight-bar 31 rotations, thereby realize an adjusting of 42 height is installed.
42 height is installed is regulated and finish by hydraulic loading system 50, it comprises hydraulic control system 51, pipeline 53, hydraulic cylinder 52 and hydraulic stem 54.Wherein, the stiff end of hydraulic cylinder 52 is hinged on the middle part of the beam 33 of vertical rack 30, hydraulic stem 54 is positioned among the hydraulic stem 52, thereby form the movable end of hydraulic cylinder, and its other end is hinged on the bottom of longitudinal beam 41, thereby can promote longitudinal beam 41 around its pin joint rotation, and the final height adjusting (as shown in Figure 6) that realizes installation 42 by the motion of the piston between hydraulic stem 54 and the hydraulic cylinder 52 with straight-bar 31.Hydraulic control system 51 can place any position easily, for example places a side of the cross bar 22 of dolly underframe 20, and it links to each other with hydraulic cylinder 52 by pipeline 53, is used for controlling the oil pressure of hydraulic cylinder 52, thereby realizes the control to the piston motion of hydraulic stem 54.
To describe the dolly that utilizes in the present embodiment below simply and carry out the whole process that undercarriage is installed, so that be expressly understood advantage of the present utility model more.
At first undercarriage is loaded on the bottom girder 21 of underframe 20 of dolly 100, makes two wheels of undercarriage lay respectively at the both sides of bottom girder 21.And adjust the position of undercarriage, clamp the pillar of undercarriage, again the lower end of pull bar 70 is connected on the link position on the undercarriage with anchor ear 80 with rubber gasket 81.At this moment, undercarriage has been finished and the preliminary fixing of dolly has been installed.Simultaneously also can be along with the bracing frame 40 that dolly is installed is further adjusted its attitude with respect to the rotation of vertical rack 30.
Then dolly is pushed into the fuselage below of undercarriage to be installed, and pulls the handle 63 of two bottom surface adjusting devices 60 respectively, in threaded sleeve 62, rotate, make threaded rod 64 constantly stretch out downwards, and leg 61 supports ground thereby drive threaded rod 64.Observe the attitude of dolly, further pull handle 63 among a small circle, realize the fine setting of threaded rod 64 height, this moment, two trailing wheels 24 of underframe 20 were unsettled, and only have front-wheel 23 still to support on the ground, and finally support the bottom surface by leg 61 common definite required installations of front-wheel 23 and two bottom surface adjusting devices 60.
Next by the coupling part 73 of rotating tension bar 70 attitude of undercarriage is adjusted at last once more, until undercarriage being adjusted to correct installation attitude.
At last, start hydraulic control system, the thrust of utilizing hydraulic stem 54 is upwards rotated the longitudinal beam 41 of bracing frame 40 with respect to straight-bar 31, thereby undercarriage is elevated to correct installation site, and finishes installment work.
What need supplementary notes is to figure 5 illustrates the force structure of whole erection dolly.As can be seen from the figure, adopt leg-of-mutton layout in its force structure morely, made overall structure very firm.
