Abstract
A kind of shear shank lifting device.It comprises shear shank assembly and Power Drive Unit, shear shank assembly comprise upper mounting plate, sliding bush apparatus, four cut support arm, lower platform and Power Drive Unit; Power Drive Unit comprises hydraulic actuating cylinder and two scissor-like jacks.Shear shank lifting device provided by the invention cannot maybe need to provide the lifting starting stage of very high thrust to utilize scissor-like jack directly lifting upper mounting plate at hydraulic actuating cylinder, so both can reduce energy ezpenditure and operating cost, but also the initial lift location of shear shank can be reduced, expand lifting stroke range and field of application, and then utilize hydraulic actuating cylinder to provide lifting thrust to make upper mounting plate reach desired height.In addition, by regulating sliding bush apparatus cutting the mode of position on support arm to change the installation site of hydraulic actuating cylinder, reach the object of the different weight of lifting, differing heights thus, therefore applied widely.In addition, this device also has reasonable in design, simple, easy to operate and low cost and other advantages.
Description
Technical field
The invention belongs to the machinery manufacturing technology field that hoists, particularly relate to a kind of shear shank lifting device.
Background technology
Jian Sheng mechanism is applied on the airport special equipments such as food conveyor, platform truck, mobile connecting bridge and portable control tower and other common apparatus in large quantities.The shear shank lifting mechanism that current manufacturer manufactures adopts the hydraulic efficiency pressure system with fixed position as Power Drive Unit mostly, but it is high with cost of upkeep that the hydraulic efficiency pressure system of fixed position is not only use, there is leakage in fluid, cause it can not adapt to the working environment of some harshness, and different power outputs and lifting stroke cannot be provided under the prerequisite of not changing mechanism size or actuating device model.And because the hoisting force of shear shank required for the initial lifting moment is very large, and hydraulic actuating cylinder cannot or need very large energy consumption just can provide due to riding position and self-characteristic.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of reasonable in design, simple, easy to operate shear shank lifting device.
In order to achieve the above object, shear shank lifting device provided by the invention comprises shear shank assembly and the Power Drive Unit for controlling the folding of shear shank assembly, described shear shank assembly comprise upper mounting plate, sliding bush apparatus, four cut support arm, lower platform and Power Drive Unit; Wherein upper mounting plate and lower platform be arranged in parallel; Cut support arm for four and be divided into two groups, front and back, often group is made up of the support arm of cutting that two middle parts are hinged, often group two of cutting on support arm cut support arm be positioned at left side one end be hinged on the bottom surface of upper mounting plate and the surperficial side of lower platform respectively, the other end is separately installed with a pulley, and two pulleys contact with the bottom surface of upper mounting plate and the surperficial opposite side of lower platform respectively; The two ends of sliding bush apparatus are fixed on two that upper end and upper mounting plate be hinged and cut between support arm top; Power Drive Unit comprises hydraulic actuating cylinder and two scissor-like jacks; Wherein the plunger rod outer end of hydraulic actuating cylinder is fixed in the middle part of sliding bush apparatus, and cylinder body outer end is hinged on lower platform surface middle part; The lower end of two scissor-like jacks is then separately fixed at the lower platform surface being positioned at and cutting outside support arm.
The maximum height of described scissor-like jack is less than the ultimate range between upper mounting plate and lower platform.
Shear shank lifting device provided by the invention cannot maybe need to provide the lifting starting stage of very high thrust to utilize scissor-like jack directly lifting upper mounting plate at hydraulic actuating cylinder, so both can reduce energy ezpenditure and operating cost, but also the initial lift location of shear shank can be reduced, expand lifting stroke range and field of application, and then utilize hydraulic actuating cylinder to provide lifting thrust to make upper mounting plate reach desired height.In addition, by regulating sliding bush apparatus cutting the mode of position on support arm to change the installation site of hydraulic actuating cylinder, reach the object of the different weight of lifting, differing heights thus, therefore applied widely.In addition, this device also has reasonable in design, simple, easy to operate and low cost and other advantages.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, shear shank lifting device provided by the invention is described in detail.
As shown in Fig. 1-Fig. 3, shear shank lifting device provided by the invention comprises shear shank assembly and the Power Drive Unit for controlling the folding of shear shank assembly, and described shear shank assembly comprises upper mounting plate 1, sliding bush apparatus 2, four cuts support arm 3, lower platform 5 and Power Drive Unit; Wherein upper mounting plate 1 and lower platform 5 be arranged in parallel; Cut support arm 3 for four and be divided into two groups, front and back, often group is made up of the support arm 3 of cutting that two middle parts are hinged, often group two of cutting on support arm cut support arm 3 be positioned at left side one end be hinged on the bottom surface of upper mounting plate 1 and the surperficial side of lower platform 5 respectively, the other end is separately installed with a pulley, and two pulleys contact with the bottom surface of upper mounting plate 1 and the surperficial opposite side of lower platform 5 respectively; The two ends of sliding bush apparatus 2 are fixed on two that upper end and upper mounting plate 1 be hinged and cut between support arm 3 top; Power Drive Unit comprises hydraulic actuating cylinder 4 and two scissor-like jacks 6; Wherein the plunger rod outer end of hydraulic actuating cylinder 4 is fixed in the middle part of sliding bush apparatus 2, and cylinder body outer end is hinged on lower platform 5 surface middle part; The lower end of two scissor-like jacks 6 is then separately fixed at lower platform 5 surface being positioned at and cutting outside support arm 3.
The maximum height of described scissor-like jack 6 is less than the ultimate range between upper mounting plate 1 and lower platform 5.
Now shear shank lifting device principle of work provided by the invention is described below: when not using this device, scissor-like jack 6 can be adjusted to extreme lower position, make the plunger rod on hydraulic actuating cylinder 4 all retract to cylinder interior simultaneously, can save space like this, now the state of this shear shank lifting device as shown in Figure 1.When need lifting upper mounting plate 1 and on load time, as shown in Figure 2, first rotate the screw mandrel on scissor-like jack 6 by staff, to make the height of scissor-like jack 6 rise, the power utilizing scissor-like jack 6 to provide and by upper mounting plate 1 upwards lifting; When scissor-like jack 6 reaches maximum height, primer fluid cylinder pressure 4, makes plunger rod protruding, and by sliding bush apparatus 2 with cut support arm 3 and make upper mounting plate 1 continue to grow tall, until reach required lift height, now the state of this shear shank lifting device as shown in Figure 3.
In addition, when lift height or lifting load difference, by regulating sliding bush apparatus 2 cutting the mode of position on support arm 3 to change the installation site of hydraulic actuating cylinder 4 upper end, thus provide different propulsive efforts and lifting stroke.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
