As Figure 1-3, a kind of crane arm mounting plate of the utility model, comprises that rail 1, liftable move load carrier and pull mechanism; Described liftable moves load carrier for carrying arm, and liftable moves load carrier and is arranged on rail 1, and liftable moves load carrier and can move along rail 1; Pull mechanism and move load carrier with liftable and be fixedly connected with, pull mechanism and can pull liftable and move load carrier and move along rail 1; Liftable moves load carrier and comprises the first shears group and the second shears group, between the shears of the first shears group by the adjustable connection of rigid mechanism distance, between the shears of the second shears group, by rope 7, connect, between the first shears group and the second shears group, by rope 7, connect; Rigid mechanism is connecting rod 6, and connecting rod 6 is provided with not equidistant through hole for connecting the shears of the first shears group; Pull mechanism and comprise that the first supporting seat 9, the second supporting seat 10, the first fixed pulley group 11, the second fixed pulley group 12, retractor device, first pull rope group 14 and second and pull rope group 15; The first supporting seat 9 is fixedly connected with rail 1 one end, and the second supporting seat 10 is slidably connected with rail 1; The first fixed pulley group 11 comprises two pulleys, and two pulleys are rotationally connected with first supporting seat 9 left and right sides, and the second fixed pulley group 12 comprises two pulleys, and two pulleys are rotationally connected with second supporting seat 10 left and right sides; One end of retractor device and the second supporting seat 10 are fixedly connected as stiff end, and the shears near the second supporting seat 10 in the other end of retractor device and the second shears group is fixedly connected as free end; First pulls rope group 14 comprises two ropes that be arranged in parallel, and one end of two ropes is fixedly connected with the first shears group respectively, walks around respectively two pulleys of the first fixed pulley group 11, and the other end is fixedly connected with the free end of retractor device respectively; Second pulls rope group 15 comprises two ropes that be arranged in parallel, and one end of two ropes is fixedly connected with the first shears group respectively, walks around respectively two pulleys of the second fixed pulley group 12, and the other end is fixedly connected with the free end of retractor device respectively; The first shears group comprises two shears, is respectively the first shears 2 and the second shears 3; The second shears group comprises two shears, is respectively the 3rd shears 4 and the 4th shears 5; The first shears 2 is connected with the second shears 3 by connecting rod 6, and the second shears 3 is connected with the 3rd shears 4 by rope 7, and the 3rd shears 4 is connected with the 4th shears 5 by rope 7; The 3rd shears 4 is provided with push rod 8 near the second shears 3 one sides; Retractor device comprises hydraulic jack 13; The load-bearing surface of shears is equipped with firm anti-skid structure.
The course of work of this example: as Fig. 1, shown in 2, the retractor device of this mounting plate can be hydraulic jack 13, and can select according to the length of arm the hydraulic jack 13 of different flexible strokes, the length of rail 1 also can be laid according to different length of boom, according to the flexible stroke counter of the length of rail 1 and hydraulic jack 13, calculate the Len req of rope 7, the second supporting seat 10 is slidably connected with rail 1, can adjust as required the distance between two supporting seats, pulley is connected with supporting seat by bearing pin, during assembling, to guarantee that pulley freely rotates, distance between two brackets of the first shears group can adapt to by the not equidistant through hole adjustment on connecting rod 6 arm of different length.
The installation step of arm is as follows:
While 1, assembling initial position (as shown in Figure 1, 2), the first segment arm 16 of small cross sections is positioned on the first shears 2 and the second shears 3, the larger second section arm 17 in cross section is positioned on the 3rd shears 4 and the 4th shears 5, the firm anti-skid structure of bracket load-bearing surface can prevent that arm from moving and trackslip, and scratches arm surface.
2, by adjusting the relative altitude of 3 groups of 2 groups of the first shears and the second shears, realize two arms to the heart, to increase efficiency of assembling and quality.
3, give hydraulic jack 13 large chamber fuel feeding, hydraulic jack 13 free ends stretch out by second and pull rope group and second fixed pulley group 12 drive the first shears groups, it is moved to the second shears group, promote the second shears group simultaneously it is moved to the first shears group.Along with constantly stretching out of hydraulic jack 13, first segment arm 16 constantly packs in second section arm 17, in the time of in position, the second shears 3 is declined, and it can be passed through below second section arm 17 and do not produce and interfere with arm 17.Hydraulic jack 13 continues to stretch out, the 3rd shears 4 will decline when the second shears 3 and the 3rd shears 4 will bump, it can be passed through below second section arm 17 and do not produce interference with arm 17, hydraulic jack 13 continues to stretch out, the second shears 3 contacts with push rod 8, promoting the 3rd shears 4 moves to the 4th shears 5, at first segment arm 16, pack second section arm 17 completely into when interior, hydraulic jack 13 stops stretching out, now the first shears group is positioned at the arm below assembling completely, use the first shears group that the arm having assembled is held up the level of, complete first, the assembling of two joint arms.
4, give hydraulic jack 13 loculus fuel feeding, hydraulic jack 13 free ends are retracted, drive 3 groups of the second shears to move to its assembling initial position, by first, pull rope group and the first fixed pulley group 11 drives the first shears groups to move to its assembling initial position simultaneously, the second shears 3 drives the 3rd shears 4 resets by itself and the rope 7 between the 3rd shears 4, the 4th shears 5 drives the 3rd shears 4 resets by itself and the rope 7 between the 3rd shears 4, when hydraulic jack 13 is all retracted, each shears resets, the 3rd joint arm 18(sectional area is greater than to second section arm) be positioned over the second shears group, and the relative altitude of adjusting the second shears group and the first shears group makes the 3rd joint arm and first, two joint arms are concentric, then repeating step 3, complete the assembling of the 3rd joint arm, complete by that analogy the assembling of whole arm.
This assembling process automaticity is high, improves efficiency of assembling and assembling yield, reduces assembling human cost.
The experiment of can stretching to the arm after having assembled of this mounting plate, basic arm (arm of cross section maximum) is fixed in the second shears group, connection is arranged on the oil circuit of the telescopic oil cylinder in arm, arm is stretched out, check whether flexible order is correct, telescopic process arm has or not extremely, can pinpoint the problems, deal with problems early, avoids the field-strip to bad arm after car load has assembled.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
