Description

The bearing pin provision for disengagement

Technical field

The utility model relates to a kind of mechanical provision for disengagement, particularly a kind of bearing pin provision for disengagement.

Background technology

The hoisting drum of driving, axle head, bearing pin very easily wear and tear, and have potential safety hazard in process of production.So, when maintenance repair, need regularly the bearing pin that is positioned at reel to be changed.As shown in Figure 1 and Figure 2, bearing pin is positioned at the center of reel, and an end of bearing pin is supported by a bearing block.Several circular holes are arranged on the outer rim of the end face of reel.

When maintenance repair, all need whole reel is taken out at every turn, take out bearing pin with press.And need to use the 30T truck crane to cooperate, and complex procedures, the workmen is more, and man-hour is long and labour intensity is big, and the job site is little, has a lot of potential safety hazards.

The utility model content

The technical problems to be solved in the utility model provides a kind of bearing pin provision for disengagement that makes things convenient for the bearing pin dismounting.

For solving the problems of the technologies described above, the provision for disengagement of the utility model bearing pin comprises that a load baffle plate, a liftout component and two draw horse leg hook, two draw an end of horse leg hook that one latch hook is set respectively, two draw the other end of horse leg hook to be connected on the load baffle plate, liftout attachment is resisted against on the described load baffle plate, is positioned at the same side of load baffle plate with latch hook.

Preferably, two draw horse leg hook and load baffle plate for removably connecting.

Preferably, two latch hooks that draw horse leg hook all toward the outer side.

Preferably, two through holes are set on the load baffle plate, two draw horse leg hook to pass two through hole respectively.

Preferably, two draw the end away from latch hook of horse leg hook that two to four adjusting pin-and-holes are set.

Preferably, also comprise two spacer pins, two spacer pins penetrate corresponding two of the load baffle plate outside respectively and regulate in the pin-and-hole, so that the load baffle plate is played position-limiting action.

When using the utility model, earlier the bearing block of axle head in the reel is pulled down.The latch hook that draws horse leg hook is penetrated in the circular hole of reel end face, preferably in two circular holes farthest.Then, two through holes with the load baffle plate put the end of regulating pin-and-hole that has that draws horse leg hook respectively.Then, the model of the jack of Shi Yonging and size penetrate spacer pin in the suitable adjusting pin-and-hole as required.At last, the base of jack is resisted against on the load baffle plate, the piston head of jack is resisted against the end of the bearing pin that is positioned at the reel center.

After adopting such structure, improved the efficient of bearing pin dismounting, energy-saving and cost-reducing, reduce mechanical one-shift and press and use, reduce workmen and upkeep operation labour intensity.

The specific embodiment

Provision for disengagement comprises following structure according to the utility model bearing pin, hereinafter will be described in detail this with reference to accompanying drawing.

The provision for disengagement of the utility model bearing pin comprises that a load baffle plate 6 and two draw horse leg hook 5, the structure of drawing horse leg hook 5 as shown in Figure 5 and Figure 6, two draw an end of horse leg hook 5 that a latch hook 52 is set respectively, 52 1 ends are tapered from middle position to latch hook to draw horse leg hook 5, make things convenient for latch hook 52 to penetrate in the circular hole 11 of reel 1 end face.Two draw the other end of horse leg hook 5 to be connected on the load baffle plate 6.Two draw the distance at a distance of farthest two circular holes 11 of horse leg hook 5 distance and reel 1 end face to equate.Load baffle plate 6, two draw the end face of horse leg hook 5 and reel 1 to form a square framework.Load baffle plate 6 is a steel bar, has certain intensity, can carry the unlikely fracture of pressure of jack 4.

Two draw horse leg hook 5 and load baffle plate 6 for removably connecting, with the reel 1 that is applicable to all kinds of different sizes.Particularly, two through holes 61, two being set on the load baffle plate 6 draws horse leg hook 5 to pass two through hole 61 respectively.Two draw the end away from latch hook 52 of horse leg hook 5 that two to four adjusting pin-and-holes 51 are set, and preferably are provided with three, as shown in Figure 5, and to determine that according to the model of jack 4 load baffle plate 6 is in the position of drawing on the horse leg hook 5.

Regulate in the pin-and-holes 51 for corresponding two that two spacer pins 7 are penetrated respectively on load baffle plate 6 outsides, the two Gen Lama leg hooks 5, with to 6 position-limiting actions of load baffle plate.Spacer pin 7 can also be used with split pin, draws horse leg hook 5 and load block with pinning.

As shown in Figure 3, when using the utility model, earlier the bearing block 3 of axle head in the reel 1 is pulled down.The latch hook 52 that draws horse leg hook 5 is penetrated in the circular hole 11 of reel 1 end face, preferably in two circular holes 11 farthest, two latch hooks 52 that draw horse leg hook 5 all toward the outer side.Then, two through holes 61 with load baffle plate 6 put the end of regulating pin-and-hole 51 that has that draws horse leg hook 5 respectively.Then, the model and the size of the jack 4 of Shi Yonging penetrate spacer pin 7 in the suitable adjusting pin-and-hole 51 as required.At last, the base of jack 4 is resisted against on the load baffle plate 6, the piston head of jack 4 is resisted against the end of the bearing pin 2 that is positioned at reel 1 center.

Above-mentioned design example only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in the utility model claim scope.
