The jack unit as one thrust device has the first roller in the power output end, one double bevel wedge connected to the first roller, one upper wedge on the double bevel wedge and one lower wedge below the double bevel wedge, one second roller between the upper wedge and the double bevel wedge, and barriers for arresting the horizontal move of the upper wedge and the lower wedge separately. The present invention has the benefit effect of obtaining very great jack force by means of the force enlarging effect of wedges, and the jack unit may be set transversely for operation in narrow space.
Description
(1) technical field
The present invention relates to a kind of jack unit.
(2) background technology
With reference to Fig. 1, traditional utensil that can produce bigger ejecting force is an oil jack, and its main element is oil cylinder 1 and piston 2, and pressure oil enters oil cylinder 1 bottom, with piston 2 jack-up, and then with weight jack-up.The weight of general thousand top energy jack-up and the fluid pressure p in the oil cylinder 1 and the diameter d of piston 2 have following relation:
F＝(πd
2p)/4 (1)
In the formula
The power of F---jack stand or weight of heavy,
P---the oil pressure pressure in the jack cylinder,
D---jack piston diameter.
This jack people are seeking to increase the method for its ejecting force always, such as the patent No. is that 92103731.7 denominations of invention are the Chinese invention patent of engineering with the pressurized type hydraulic jack, and the patent No. is 91203991.4, denomination of invention is the Chinese utility model patent of double-stage hydraulic jack, this class invention is owing to only consider on this body structure of jack, the oil cylinder fluid pressure p that is equivalent to only depend on the diameter of piston d that increases it or improves it reaches the purpose that increases ejecting force, and these methods are very limited to the increase of ejecting force obviously.
Especially, if the workplace of jack is in the condition (for example changing the rubber plinth of express highway, high speed railway) of narrow and small gap space, because the limitation of narrow and small gap space position, said method often can't use.This is because cylinder diameter d can't strengthen, moreover, because technical restriction, in-oil cylinder oil pressure also can not be too high due to.
(3) summary of the invention
In order to overcome the hypodynamic shortcoming that ejects of jack unit in the prior art, the invention provides a kind of jack unit that the super large ejecting force is provided, this jack unit is particularly useful for narrow and small gap space.
The technical scheme that the present invention solves its technical matters is: a kind of jack unit, comprise thruster, the clutch end of described thruster is connected with a double inclined plane voussoir by first rolling member, there is last voussoir the top of described wedge block with two inclined planes, there is lower wedge block the below of described wedge block with two inclined planes, the inclined-plane of described upward voussoir is relative with the ramp of wedge block with two inclined planes, the inclined-plane of described lower wedge block is relative with the lower inclined plane of wedge block with two inclined planes, be shelved with second rolling member between the inclined-plane of described upward voussoir and the ramp of described wedge block with two inclined planes, be shelved with second rolling member between the lower inclined plane of the inclined-plane of described lower wedge block and described folding wedge piece, described upward voussoir and lower wedge block are respectively equipped with the block piece that stops the own level displacement.
Further, the last lower inclined plane symmetry of described wedge block with two inclined planes.
Further, the described end face of going up voussoir is a horizontal surface, and the bottom surface of described upward voussoir is parallel with the ramp of described wedge block with two inclined planes, and the end face of described lower wedge block is parallel with the lower inclined plane of described folding wedge piece, and the bottom surface of described lower wedge block is a horizontal surface.
Further, the ramp of described wedge block with two inclined planes leaning angle with respect to the horizontal plane is 1 °～30 °.
Further, the described bibeveled ramp leaning angle with respect to the horizontal plane of stating is 3 °～20 °.
Further, described thruster has 1～6, and when a plurality of thruster was arranged, these several thrusters promptly can be side by side arranged, and also can end to end form arrange.A plurality of thrusters can be arranged side by side, at this moment, increase wedge block with two inclined planes and reach the width of going up lower wedge block, are applied to occasions such as building moves usually; A plurality of thrusters also can end to endly be arranged, and with the transmission of realizable force, provide bigger horizontal thrust, can obtain bigger ejecting force, and this structure is suitable for the operation of narrow space.
Further, described thruster is oil jack or screw rod.
Further, described first rolling member is a ball, and second rolling member is a roller.
Further, described bottom surface of going up voussoir is provided with the roller of band retainer, and roller contacts with the ramp of wedge block with two inclined planes, and the end face of described lower wedge block is provided with the roller of band retainer, and roller contacts with the lower inclined plane of wedge block with two inclined planes.
Further, last block piece is the described block piece of going up voussoir, and following block piece is the block piece of described lower wedge block, and last voussoir front end face is connected with last block piece by the balance ball.
Further, the front end face of described thruster power take-off shaft is provided with the ball that has retainer, and described ball contacts with the aft end face of wedge block with two inclined planes; The described front end face of going up voussoir is provided with the balance ball that has retainer, and described balance ball contacts with the aft end face of last block piece.
Principle of work of the present invention is: thruster applies transverse force (P), this transverse force acts on the wedge block with two inclined planes, rely on stressed transmission, last voussoir just can produce ejecting force (F) at double, and the size of this ejecting force is decided by the size of thrust and the angle of wedge size α (being the inclined-plane of voussoir and the angle between the horizontal surface) of voussoir: can be got by Fig. 2
N＝P/(2sin?α) (2)
Can get by Fig. 3 again
F＝N?cos?α (3)
Comprehensive above-mentioned two formulas obtain at last
F＝P/(2tg?α) (4)
If get tg α=0.05 then have
F＝10P
Therefore vertical ejecting force is ten times of horizontal thrust when tg α=0.05.
Beneficial effect of the present invention is: 1. the present invention utilizes the amplification of voussoir to power, reaches the purpose that obtains the super large ejecting force.2. when using thruster is laterally placed, then the present invention is specially adapted to work under the condition of narrow and small gap space.
