It is connected to support base 3 and safety basement 13, the first support plate 4 is fixed on support frame 1, and is fixedly mounted in the first support plate 4
There is hoist engine 5, wirerope 6 is provided on hoist engine 5, and wirerope 6 fits with movable pulley 8, wirerope 6 includes king wire
Rope 601, secondary wirerope 602, connector 603, sponge protective case 604, shield 605, and main rope 601 and secondary wirerope
602 are connected by connector 603, while secondary wirerope 602 is fixedly connected by connector 603 with the second lifter plate 702, secondary
Sponge protective case 604 is enclosed on wirerope 602, and the both ends of secondary wirerope 602 are located inside shield 605, and shield
605 are installed on connector 603, and main rope 601 is connected with four secondary wirerope 602, and secondary wirerope 602 is about lifter plate
7 A shaft centre line is symmetrical arranged, and lifter plate 7 can smoothly be driven to carry out raising and lowering, when appearance one secondary wirerope
When 602 fracture, it will not influence and too much influence is caused to lifter plate 7, safety is higher, and the both ends of movable pulley 8 and support frame 1 are living
It is dynamic to connect, it is provided with piston rod 10 on hydraulic cylinder 9, and hydraulic cylinder 9 is fixed in the second support plate 11,11 outside of the second support plate
Spacing between end face is equal to the length of the first lifter plate 701, and the first lifter plate 701 and the second support plate 11 are parallel to each other,
It is structurally reasonable to which hydraulic cylinder 9 can drive the stable raising and lowering of the first lifter plate 701 by piston rod 10, second
Fagging 11 is an integral structure by fixing piece 12 with locating rod 14, the top of locating rod 14 and the fixed weldering of the second lifter plate 702
It connects, and the length of locating rod 14 is less than the length of sliding bar 15, the length of locating rod 14 is that hoist engine 5 is pulled by wirerope 6
7 range of lifter plate, thus hoist engine 5 traction and hydraulic cylinder 9 promoted two kinds can combine carry out use safety
Height, bottom end and 16 top end surface of cushion socket of locating rod 14 fit, and locating rod 14 and cushion socket 16 correspond, to make
When obtaining the whereabouts of locating rod 14, it can fairly fall on cushion socket 16, good damping effect, fixing piece 12 is worn from sliding groove 17
It crosses, the length of sliding groove 17 is consistent with the height of safety basement 13, it can guarantee that fixing piece 12 has enough movings range, thus
Enable the second support plate 11 as locating rod 14 freely moves up and down, locating rod 14 is worn from safety basement 13
It crosses, and the bottom end of locating rod 14 is provided with cushion socket 16, offers sliding groove 17 on safety basement 13, sliding bar 15 is from lifter plate
It is passed through in 7, lifter plate 7 includes the first lifter plate 701, the second lifter plate 702, connecting rod 703 and fixing groove 704, and first
The bottom end surface of lifter plate 701 is provided with connecting rod 703, while the top of the second lifter plate 702 offers fixing groove 704, even
Extension bar 703 is engaged with 704 phase of fixing groove, when the first lifter plate 701 falls because of the failure of hydraulic cylinder 9, passes through connecting rod
703 with fixing groove 704, the first lifter plate 701 can be made to be sticked on the second lifter plate 702, prevented on the first lifter plate 701
Cargo fall, using effect is good, and the first lifter plate 701 and 702 top end surface of the second lifter plate are in same level, and
The top end surface of one lifter plate 701 is in concave-convex striated structure, while the top phase at the both ends of the first lifter plate 701 and piston rod 10
The surface of connection, the first lifter plate 701 and the second lifter plate 702 is in a plane, places article, and first liter convenient for people
Dropping 701 surface of plate has antiskid effect, and article is not easy to slip down from the first lifter plate 701, structurally reasonable, connecting rod 703
It is distributed with the equal rectangular array of fixing groove 704, and the tapered structure in 703 bottom end of connecting rod, when connecting rod 703 falls, is convenient for
Connecting rod 703 fastens with fixing groove 704, so that connecting rod 703 be avoided to touch the notch edge of fixing groove 704, influences card
Effect is closed, and the bottom end of above-mentioned sliding bar 15 is welded in fixed plate 2.
The working principle of the present embodiment: this is used for the lifting device of construction, in use, can pass through support base 3
It is with safety basement 13 that the device fixed placement is good, when needing to carry out conveying articles, cargo is placed on lifter plate 7, is made
Hoist engine 5 powers on and makes its start-up operation, and hoist engine 5 starts constantly to furl wirerope 6 by movable pulley 8, thus logical
Crossing main rope 601 and secondary wirerope 602 can smoothly drive lifter plate 7 to be risen along sliding bar 15, on lifter plate 7
Locating rod 14 can be equally driven to rise during rising, locating rod 14 is carried out in sliding groove 17 by fixing piece 12 to moving up
It is dynamic, and then the second support plate 11 is driven to rise, such second support plate 11 is just moved up as lifter plate 7 synchronizes, when secondary steel
When the top or bottom end of cord 602 are broken, shield 605 can be blocked secondary wirerope 602, prevent it from quickly throwing away,
And then impact force when secondary wirerope 602 is thrown away is reduced, fracture occur among wirerope 602 makes, and sponge protective case 604 can be with
It plays a protective role, prevents wirerope 602 from damaging when throwing away to cargo, when arriving certain altitude by the promotion of hoist engine 5,
Hoist engine 5 stops working, and at this time powers on hydraulic cylinder 9 and makes its start-up operation, and hydraulic cylinder 9 drives the by piston rod 10
One lifter plate 701 rises, and then carries out being delivered up material, and when there is 9 operation irregularity of hydraulic cylinder, the first lifter plate 701 exists
It can be dropped into dropping process on the second lifter plate 702, lifter plate 7 can be prevented by main rope 601 and secondary wirerope 602
It falls down, so as to prevent cargo from falling bring security risk, when there is the fracture of wirerope 6, in locating rod 14
Under effect, lifter plate 7 is by the slide downward on safety basement 13 of locating rod 14, so that guaranteeing is not in because wirerope 6 is disconnected
Splitting causes lifter plate 7 the phenomenon that inclination causes cargo to fall occur, can be quick to locating rod 14 under the action of cushion socket 16
Impact force when whereabouts carries out certain buffering, ensure that equipment is not damaged, improves its service life, and here it is the devices
Whole work process.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
