Example 1
Referring to fig. 1 to 6, this embodiment discloses a specific embodiment of a column lifter (hereinafter referred to as a "lifter") having an M-shaped bending arm.
The upright lifting machine with the M-shaped bending arms comprises a first upright 1 and a second upright 2, wherein the first bending arms 11 and the second bending arms 12 are symmetrically arranged on two sides of the first upright 1, and the first bending arms 11 and the second bending arms 12 are in a first M shape after being bent; the two sides of the second upright post 2 are symmetrically provided with a third bending arm 21 and a fourth bending arm 22, the third bending arm 21 and the fourth bending arm 22 are in a second M shape after being bent, and the first M shape and the second M shape are symmetrically arranged; the ends of the first bending arm 11, the second bending arm 12, the third bending arm 21 and the fourth bending arm 22 are respectively provided with a buffer tray 3.
Specifically, when the existing straight arm type double-column lifter lifts a short wheelbase vehicle type, the straight arm possibly blocks a tire and cannot lift the tire, or four trays cannot be accurately and simultaneously aligned with lifting points during lifting; when lifting new energy battery car, because the battery of this type car mostly sets up in the chassis, the scope of lifting the point is less, in case the inaccurate condition of lifting the position appears, just probably damages the battery, when using present straight arm shape to lift the machine, also can exist and lift the defect that four trays can't accurately aim at simultaneously to lifting the point when lifting. In view of the above drawbacks, referring to fig. 1 to 6, in order to improve the flexibility of the lifting arm, so that the lifting arm can lift a short-wheelbase vehicle type and a new energy battery vehicle, the four lifting arms of the embodiment are bending arms, namely, bending points of the first bending arm 11, the second bending arm 12, the third bending arm 21 and the fourth bending arm 22 are located at 1/2 of the maximum length of the bending arm, the maximum length of the bending arm refers to the maximum unfolding length of the bending arm when the bending arm is not bent, and the bending points exist, so that the flexibility of the lifting arm is greatly improved, and when the short-wheelbase vehicle type is encountered, the short-wheelbase vehicle type is lifted by bending to bypass the tire and then searching for the lifting point, and the lifting arm in the shape of the first M and the second M is used for lifting the short-wheelbase vehicle type; for another example, when four lifting points of the vehicle cannot be accurately and simultaneously lifted under the condition of the straight arm, one or more lifting arms can be bent, so that the lifting arms are accurately aligned to the lifting points to lift, the condition that the lifting points are exceeded can be avoided, and the damage to the battery is avoided.
Referring to fig. 4 to 6, in the present embodiment, the composition and bending principle of the first bending arm 11, the second bending arm 12, the third bending arm 21 and the fourth bending arm 22 are the same, and the first bending arm 11 is described below as an example, the first bending arm 11 includes a first arm 111 and a second arm 112, the first arm 111 is hinged to the first upright 1, and the first arm 111 and the second arm 112 rotate around the bending point; the bending point comprises a rotary drum 4, a core bar 5, an outer conical tooth 6 and an inner conical cap 7, wherein a central hole 41 is formed in the rotary drum 4, a first step 411 is formed in the central hole 41, a second step 51 is formed in the core bar 5, a spring 42 is arranged between the first step 411 and the second step 51, and the top of the core bar 5 is connected with the inner conical cap 7; the outer conical teeth 6 are fixed at the top of the second arm 112, the inner conical cap 7 is matched with the outer conical teeth 6, the inner conical cap 7 is provided with internal teeth, the outer conical teeth 6 are provided with external teeth, after the internal teeth and the external teeth are meshed, an included angle between the first arm 111 and the second arm 112 is locked, one side of the inner conical cap 7 is provided with a stop plane 71, a stop block 72 is arranged beside the stop plane 71, the stop plane 71 is matched with the stop block 72, on one hand, the upward and downward movement direction of the inner conical cap 7 along the stop plane 71 can be limited, on the other hand, the axial rotation of the inner conical cap 7 can be limited, and the locking bending point can be realized; the bottom of the core rod 5 is exposed from the bottom surface of the second arm 112. Specifically, when the second arm 112 needs to be rotated, the first bending arm 11 needs to be lowered to the ground, in this process, the bottom of the core rod 5 is pushed upwards by the ground, the spring 42 between the first step 411 and the second step 51 is compressed, the inner conical cap 7 is driven to move upwards along the stop plane 71, so that the inner conical cap 7 and the outer conical teeth 6 are disengaged, at this time, the second arm 112 and the first arm 111 can flexibly rotate, after the second arm 112 rotates in place, the first bending arm 11 is lifted to enable the bottom of the core rod 5 to leave the ground, under the action of the spring 42, the inner conical cap 7 is driven to move downwards along the stop plane 71 and form engagement with the outer conical teeth 6, the second arm 112 and the first arm 111 are fixed at a certain angle, the included angle between the second arm 112 and the first arm 111 is locked at any time through the cooperation of the inner conical cap 7 and the outer conical teeth 6, and the bending angle adjustment is safe and efficient.
When the bottom of the core rod 5 is propped up on the ground, in order to prevent the upward stroke of the core rod 5 for driving the inner cone cap 7 from being too high, the exposed portion of the core rod 5 is smaller than the height of the stop block 72, i.e., even if the exposed portion of the core rod 5 is completely propped into the central hole 41, the inner cone cap 7 is not made to exceed the height range of the stop block 72.
In order to increase the rotation range of the second arm 112 around the bending point and improve the flexibility of the bending arm, the top surface and the bottom surface of the second arm 112 are respectively provided with an L-shaped reinforcing plate 113, the L-shaped reinforcing plate 113 is hinged with the first arm 111 through the bending point, the L-shaped reinforcing plate 113 enables the first arm 111 and the second arm 112 to be staggered when being stretched, namely not on a straight line, and the staggered advantage is that the included angle between the first arm 111 and the second arm 112 can be 0 degree or close to 0 degree at minimum, so that the first arm 111 and the second arm 112 can be folded by 0 degree or close to 0 degree and the occupied ground area is minimized under the condition that the lifting machine is not used.
