The specific embodiment
In Fig. 1, Fig. 2, a kind of large-scale hardware lifting appliance, hardware 1 lower end is provided with at least two bottom brackets 2, and hardware 1 upper end opposite position is provided with bracket 3;
Connect by many steel strand 4 between bracket 3 and the bottom bracket 2, steel strand 4 one ends are provided with ground tackle 5, and the other end is provided with oil cylinder 6; In this example, bracket 3 and bottom bracket 2 are symmetrically arranged with four groups of apertures, are used to install steel strand 4, according to hardware 1, are the rigidity requirement of miter gate in this example, determine the diameter and the radical of steel strand.Steel strand one end is fixing with ground tackle 5, and for ease of operation, ground tackle 5 is arranged on the lower end of steel strand usually, and every group of steel strand are selected the size of oil cylinder 6 for use according to the tension force size, and oil cylinder 6 is arranged on the bracket and is connected with steel strand 4.Two covers are after totally eight groups of clamping systems deploy, start electrical controller and carry out integral tension, front and back position between every group of bracket 3 or bottom bracket 2 and hardware 1 is furnished with strain gauge, monitors in stretching process, prevents hardware 1 distortion.For ease of timely adjustment, electrical controller both can whole be controlled, and also can control separately.For preventing that steel strand and member direct contact from causing damage, between steel strand and member, be aided with wood block filler and support.
Position near steel strand on the described bracket 3 is provided with at least one block 9, the shackle plate 8 that it is B that the middle part is provided with two spacings, and the balance sling 11 on the hoist cable 12 is connected with shackle plate 8 by bearing pin 13.
In Fig. 7, spacing B's between the thickness of described balance sling 11 and two shackle plates 8 is poor, in more than 1/4 of balance sling 11 thickness, and be not more than 40mm, be that balance sling 11 also has a bigger gap between two shackle plates 8, be provided with between balance sling 11 and the block 9 and be used to jack 10 that balance sling 11 is moved along bearing pin 13 axis.Block 9 is the stressed bases as jack 10, by jack 10 positions of fine setting balance sling 11 on bearing pin 13, perhaps making balance sling 11 drive bearing pin 13 moves in the hole of shackle plate 8, promptly finely tune the relative position between balance sling 11 and the shackle plate 8, thereby make distance C between the center of gravity line of the plumb bob vertical of balance sling 11 and hardware 1 as far as possible for minimum, thereby adjust hardware 1, it in this example the attitude of miter gate, miter gate tilts when preventing to lift by crane, and center of gravity is adjusted back in place and miter gate can be sling by balance sling and hoist cable.
The scheme of optimizing is that described block 9 is two, lays respectively at the position of bracket 3 two ends near steel strand.
In Fig. 5, Fig. 6, described balance sling 11 two ends are provided with and hoist cable 12 bonded assembly holes, and the below, middle part is provided with arc, and arc is provided with pin shaft hole.
In Fig. 3, Fig. 4, described bracket 3 two ends are provided with and steel strand 4 bonded assembly holes, are provided with block 9 with the side in steel strand 4 bonded assembly holes, and the middle part is provided with two shackle plates 8.
Concrete lifting step is:
1, according to the weight and the version of miter gate 1, design bracket 3 and 2 liang of covers of bottom bracket promote with 11 liang of covers of balance sling.Balance sling 11 adopts bearing pin 13 to be connected with bracket 3 by shackle plate 8.For realizing the fine setting of miter gate center of gravity, on bracket 3, be welded with block 9, between block 9 and balance sling 11, jack 10 is installed.Be arranged with totally four circular holes at the two ends of each bracket 3 and bottom bracket 2, be used for fixing stretch-draw steel strand 4 and oil cylinder 6.According to gate structure and weight, adopt 8 groups of steel strand 4 altogether, symmetric arrangement 8 group oil cylinders 6 are used for stretch-draw packer word strobe on bracket 3.
2, make bottom bracket 2 and bracket 3.In originating firm, made carriage 2 and bracket 3, and be up to the standards, steel strand 4 and the oil cylinder 6 selected for use have been checked that it is qualified to confirm by the program and the method for correlated quality administrative provisions by design paper.
3, packing apparatus is installed.Install carriage 3, bottom bracket 2, steel strand 4, ground tackle 5 and oil cylinder 6 according to design paper, and between miter gate and bracket 3 front and back positions, arrange pressure sensor 7, avoid steel strand 4 directly to contact in the miter gate front and back with an amount of wooden unit of location arrangements between the steel strand 4, in order to avoid damage steel strand 4 with miter gate; The ground tackle 5 and oil cylinder 6 and steel strand tension detecting device of steel strand are installed then;
4, start electrical controller driving oil cylinder 6 with steel strand 4 tensionings, every group of steel strand load is no more than 200 tons.Detect the tension force size in the stretching process, in order to avoid miter gate distortion and break steel strand 4 in good time.
5, try to hang behind the whole installation qualifications of whole device.Miter gate can put down miter gate, allow hoisting wirerope not stress if any inclination, uses the relative position of jack 10 fine setting balance slings 11 and shackle plate 8 then according to the miter gate direction of tilt, and micro-adjustment is made in the Heave Here.
6, in whole miter gate lifting and the decline process, design has special detecting device that miter gate and tackling system are detected in real time.
