Description
Technical field
The utility model is related to lifting machine technical field, specifically a kind of scissor-type lifting machine auxiliary body.
Background technology
Current scissor-type lifting machine overcomes the method at active force dead point to be by improving equipment original height in advance, so as to keep away
Exempt to directly act on and put forth effort dead point；This mode causes equipment original height higher, in the case where lift height is fixed, if
Standby liftable scope is small.
Utility model content
To solve the above problems, the utility model is to provide a kind of scissor-type lifting machine auxiliary body.
The utility model to achieve the above object, prop up by a kind of scissor-type lifting machine auxiliary body, including a rotatable connection
Point, an oil cylinder strong point and an auxiliary lifting strong point, rotatable connection fulcrum is the axle welded with connecting lever, its activity
End is coaxial with fixing end under scissor-type lifting machine, realizes its spinning movement by sliding bearing, the oil cylinder strong point is by a length
Axle is connected with cylinder pedestal, and its fixed form is that expansion sleeve fixes major axis with the oil cylinder strong point, is added at the auxiliary lifting strong point
One slider roller, slider roller is connected by roller bearing pin with the auxiliary lifting strong point, and wherein slider roller is with roller bearing pin
Movable connection, the auxiliary lifting strong point and support body rigid friction when avoiding lifting by roller.
Preferably, the rotatable connection fulcrum of the connecting lever and the oil cylinder strong point and be rotatably connected fulcrum and auxiliary lifting branch
Support point line angle is 120 °.
Preferably, the connecting plate between the rotatable connection fulcrum and the oil cylinder strong point is processed using independent monoblock steel plate
Form, the connecting lever between rotatable connection fulcrum and the auxiliary lifting strong point is processed using two pieces of steel plate carry out group welderings；Rotation
Above-mentioned two structure is fixed together by welding by the axis body of connection fulcrum, and its movable end adds the constraint side of groove using boss
Formula prevents that crank arm mechanism departs from support body to equipment when in use, while being readily disassembled during maintenance.
Crank arm mechanism uses symmetrical dual system mounting means, it is to avoid the left and right that discontinuity is caused lifts asynchronous or frame
The situation of body distortion, during connecting lever initial position, scissor-type lifting machine lifting force is more than the power needed for connecting lever auxiliary lifting, now turns
Scissor-type lifting machine is lifted certain altitude by arm by rotating, while cylinder pedestal position is shifted along base direction, so that
Scissor-type lifting machine is departed from active force dead point and follow-up lifting action is realized with this.
The utility model is, in the case where lift height is fixed, equipment liftable scope to be improved as far as possible, biography is overcome
System method can not make the problem of scissor-type lifting machine is preferably minimized, and first leave equipment lifting using crank arm mechanism and put forth effort dead point again
Conventional lifting is carried out, realization can allow equipment not influence the lifting of equipment to act again while being reduced to minimum.

Embodiment
As shown in figures 1-8, a kind of scissor-type lifting machine auxiliary body, including rotatable connection fulcrum 1, an oil cylinder branch
Support point 2 and an auxiliary lifting strong point 3, rotatable connection fulcrum 1 is the axle 101 welded with connecting lever 4, and its movable end is with cutting
Fork lifter 5 times fixing ends 102 are coaxial, and its spinning movement is realized by sliding bearing 103, and the oil cylinder strong point 2 is by one
Major axis 201 is connected with cylinder pedestal 202, and its fixed form is that expansion sleeve 203 fixes major axis with the oil cylinder strong point 2, and auxiliary is lifted
Add a slider roller at ascending branch support point 3,301, slider roller 301 is connected by roller bearing pin 302 with the auxiliary lifting strong point 3,
Wherein slider roller 301 and roller bearing pin 302 are movable connection.
The rotatable connection fulcrum 1 of connecting lever 4 and the oil cylinder strong point 2 and be rotatably connected fulcrum 1 and the line of the auxiliary lifting strong point 3
Angle is 120 °, and the effect of connecting lever 4 is the mechanism for opening the cross device active force dead point of scissor-type lifting machine 5, overcomes scissor-type
The infinitely great situation of its active force caused by trigonometric function relation of the lifting machine 5 in initial open because of power with open angle.
Connecting plate 6 between the rotatable connection fulcrum 1 and the oil cylinder strong point 2 is processed using independent monoblock steel plate,
Connecting lever 4 between rotatable connection fulcrum 1 and the auxiliary lifting strong point 3 is processed using two pieces of steel plate carry out group welderings；Rotation connects
Above-mentioned two structure is fixed together by welding by the axis body for connecing fulcrum 1, and its movable end adds the constraint side of groove using boss
Formula prevents that crank arm mechanism departs from support body to equipment when in use.
Utility model works principle:The power that cylinder pedestal 202 is born acts on major axis 201, and major axis 201 passes through expansion sleeve
203 transfer a force to the oil cylinder strong point 2, and power is acted on into auxiliary lifting by the connecting lever 4 of the fulcrum 1 formation lever that is rotatably connected supports
Point 3, then conducted power to scissor-type lifting machine 5 by roller bearing pin 302 and slider roller 301, because scissor-type lifting machine 5 is lifted
Lift is more than the power needed for the auxiliary lifting of connecting lever 4, and now scissor-type lifting machine 5 is lifted certain altitude by connecting lever 4 by rotating,
The position of cylinder pedestal 202 is set to be shifted along the direction of base 7 simultaneously, so that scissor-type lifting machine 5 is departed from active force dead point and come with this
Realize follow-up lifting action.
The schematical embodiment of the utility model is the foregoing is only, model of the present utility model is not limited to
Enclose.Any those skilled in the art, the made equivalent change on the premise of design of the present utility model and principle is not departed from
Change and change, the scope of the utility model protection all should be belonged to.
