Plate fits.
Fillet processing is done in the lower end of the inner side edge of the connecting plate, and the radius of the fillet and the central axis of pin shaft arrive
Fixed plate is equidistant.
The thickness of the transverse slat two is identical as the thickness of fixed plate.
The support plate is ear template, and two connecting plates are located between two support plates.
Jack is offered on the end that the pin shaft is located at outside support plate, be provided in the jack prevent pin shaft from
The split pin to fall off on hold-down support.
The gain effect of the utility model is:
When in use, hold-down support is mounted by means of bolts on crane end carriage the utility model, so being
Removably, it when use, may be mounted on crane end carriage, when unwanted, can dismantle, and this is practical new
Type be it is folding, when needing replacing, support base is rotated upwards around pin shaft, it is horizontal when rotating to horizontal position
The inner side edge of plate one and the inner side edge of connecting plate fit with fixed plate, prevent support base from continuing up rotation, protect support base
It holds in horizontal position, then jack is placed on the lower section of support base, so that jack is jacked up crane end carriage upwards, then more
Wheel change or bearing, do not need using when, support base is rotated down around pin shaft, rotate to upright position when
It waits, since the length dimension of the connecting plate is greater than width dimensions, support base is in a horizontal position relative to upright position
When, the size of the overall width of the utility model is reduced, and by folding up the utility model, is arrived in orbit centre
When workshop Edge Distance is small, interference is not generated, is not influenced wheel dismounting or wheel bearing replacement, is made the normal work of lifting function
Make；It is provided with the split pin for preventing pin shaft from falling off from hold-down support in the jack, substantially increases security performance, to prevent
When changing, pin shaft and support base are split away off from hold-down support suddenly, so that crane end carriage is fallen downwards, thing of hurting sb.'s feelings
Therefore.The utility model structure is simple, and design rationally, can fold, and when preventing orbit centre small to workshop Edge Distance, produces
Raw interference, greatly improves security performance.

Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.
Referring to figure 1, figure 2 and figure 3, serial number in figure: 1 it is hold-down support, 2 is support base, 3 is bolt, 4 is fixed plate, 5
It is pin shaft for support plate, 6,7 be connecting plate, 8 be transverse slat one, 9 is that transverse slat two, 10 is split pin, 11 crane end carriages, 12 is thousand
Jin top and 13 is wheel.
A kind of folding end carriage jacking apparatus of the utility model is removable on crane end carriage 11 including being fixedly mounted on
The hold-down support 1 unloaded and the support base 2 being hinged on hold-down support 1, the hold-down support 1 include being fixedly mounted on crane
Symmetrically arranged two support plates 5 in the two sides of the lower section of fixed plate 4 and fixed plate 4 on end carriage 11, the fixed plate 4
It is mounted on crane end carriage 11 by bolt 3, the support base 2 is hinged between two support plates 5 by pin shaft 6, institute
The support base 2 stated is 90 ° around the rotation angle of pin shaft 6, and the support base 2 includes being cut with scissors by pin shaft 6 with two 5 phases of support plate
The transverse slat 1 and two that two connecting plates connect, 7, two connecting plates, 7 top is laterally arranged between the end of fixed plate 4
Far from the transverse slat 29 being laterally arranged between the end of fixed plate 4, the length dimension of the connecting plate 7 is big for a 7 lower section of connecting plate
In width dimensions, the transverse slat 1 make support base 2 around pin shaft 6 be rotated upwardly to horizontal position after stop rotating, the cross
Plate 29 make support base 2 around pin shaft 6 be rotated downwardly to upright position after stop rotating, the connecting plate 7 rotates to water around pin shaft
When prosposition is set, the inner side edge of the connecting plate 7 and the inner side edge of transverse slat 1 fit with fixed plate 7, the connecting plate
7 when rotating to upright position around pin shaft 6, and the inner side edge of the transverse slat 29 fits with fixed plate.
Do fillet processing, the radius of the fillet and the central axis of pin shaft in the lower end of the inner side edge of the connecting plate 7
To being equidistant for fixed plate.
The thickness of the transverse slat 29 is identical as the thickness of fixed plate 4.
The support plate 5 is ear template, and two connecting plates 7 are located between two support plates 5.
Jack is offered on the end that the pin shaft 6 is located at outside support plate 5, being provided in the jack prevents pin shaft
The split pin 10 to fall off from hold-down support.
When in use, hold-down support 1 is fixedly mounted on crane end carriage 11 the utility model by bolt 3, institute
Be it is dismountable, when use, may be mounted on crane end carriage 11, when unwanted, can dismantle, Er Qieben
Utility model be it is folding, when needing replacing, by support base 2 around pin shaft 6 upwards rotate, rotate to horizontal position
When, the inner side edge of transverse slat 1 and the inner side edge of connecting plate 7 fit with fixed plate 4, and prevent support base 2 from continuing up rotation,
So that support base 2 is maintained at horizontal position, then jack 12 is placed on the lower section of support base 2, jacks up jack 12 upwards
Crane end carriage, then more wheel change 13 or bearing, do not need using when, by support base 2 around pin shaft 6 to backspin
Turn, when rotating to upright position, since the length dimension of the connecting plate 7 is greater than width dimensions, support base 2 is in water
When prosposition is set relative to upright position, the size of the overall width of the utility model is reduced, by the way that this is practical new
Type is folded up, and when orbit centre is small to workshop Edge Distance, does not generate interference, does not influence the dismounting of wheel 13 or wheel
Bearing replacing works normally lifting function；The opening for preventing pin shaft from falling off from hold-down support is provided in the jack
Pin 10, substantially increases security performance, and when to prevent changing, pin shaft and support base are split away off from hold-down support suddenly, makes
Crane end carriage falls downwards, and casualty accident occurs.The utility model structure is simple, and design rationally, can fold, prevent track
