Abstract

The utility model discloses an internal bearing hoisting device. A transmission mechanism is composed of a screw rod, a gland nut, a locking nut, a sleeve barrel, a connecting rod division head and a support hinge. An internal stay base plate and a rubber plate are controlled to move in the shaft center direction or the opposite direction of the screw rod and to be inserted into a barrel-shaped object. After the rubber plate presses tightly the wall of a hoisted object, a hoisting machine is started. The utility model can replace onerous manual operation or complex hoisting machinery.

Description

The inner bearing type lifting appliance

The utility model relates to the improvement of article lifting appliance, particularly a kind of inner bearing type lifting appliance.

Some volumes are big, heavier tubular article, the parts of weight, as the coil of voltage transformer etc., move during assembling, lift by crane all compare difficult.Modern enterprise is finished above-mentioned work with price costliness, baroque lifting appliances such as magnetic lifting machines, in, peanut operates by hand, expends time in, manpower, and is also dangerous.

The purpose of this utility model provides a kind of simple in structure, cheap, safety of operation, convenience, saves manpower, the inner bearing type lifting appliance of time, solves the aforesaid drawbacks.

The purpose of this utility model is achieved in that on the top of a screw rod, and suspension ring are installed.At the external diameter of screw rod, a sleeve more bigger than screw diameter is installed.On the top of sleeve, the hold-down nut of a band handle is installed.On hold-down nut top, a jam nut is installed.The bottom that has the connecting rod of two same structures to be inserted in screw rod separately in the bottom of sleeve, 2 connecting rods separately between, a spring is installed, be enclosed within on the screw rod external diameter.The screw rod base is installed in the bottom of screw rod.Two connecting rods rely on connecting rod, hinge and inner support bottom plate connecting separately, and the inner support base plate can be 2 to 8, and the outside of every interior fagging all is equipped with identical rubber plate.

During use, collude with loop wheel machine suspension ring are triggered, jam nut and hold-down nut are rotated up, under the effect of spring, two connecting rods distance separately increase, and connecting rod spurs the inner support base plate under an effect of hinge simultaneously to the screw rod axis direction.When the rubber plate outside the inner support base plate can insert the internal diameter that needs lifting and is the object (as large-scale coil) of tubular, the utility model is inserted lifting inner appropriate location with loop wheel machine.Rotate the handle of hold-down nut by hand, hold-down nut is moved downward, hold-down nut forces sleeve to move downward, compress top connecting rod separately, the screw rod base props up the connecting rod parted hair below the top simultaneously, and two connecting rods separately can only be in opposite directions near moving, and connecting rod outside inner support base plate that promotes under a hinge effect moves, rubber plate compresses the inwall of lifting object, and spring also is compressed simultaneously.Rotate jam nut then by hand, jam nut is moved downward tighten up hold-down nut, prevent that it is loosening.Upwards start loop wheel machine this moment, and object is steadily sling, and puts into preposition.

Owing to adopt the utility model, to form with screw rod, nut, connecting rod, a hinge, base plate, simple in structure, safe in utilization, inner bearing type lifting appliance easily replaces expensive lifting appliance or artificial heavy and unsafe carrying work such as magnetic loop wheel machine.

In conjunction with the accompanying drawings and embodiments, comment thin description structure of the present utility model:

Accompanying drawing is the scheme drawing of the structure of the utility model embodiment.Suspension ring [6] are installed on top in screw rod [7].External diameter in screw rod [7] is installed a sleeve [4] than screw rod [7] slightly larger in diameter.A hold-down nut [5] is installed on top in sleeve [4].On hold-down nut [5] top, a jam nut [8] is installed.In sleeve [4] bottom, the connecting rod that two same structures are arranged separately [9] is inserted in the bottom of screw rod [7], separately between [9], a spring [12] is installed at two connecting rods, is enclosed within on the external diameter of screw rod [7].Two connecting rod parted hairs [9] are connected with 4 inner support base plates [3] with 8 connecting rods [11], and the outside that inner support base plate [3] is every is equipped with identical rubber plate [2].The screw rod base [1] that the bottom of screw rod [7] installs and fixes.Connecting rod [9], connecting rod [11] and inner support base plate [3] separately relies on a hinge [10] to be connected.
