Abstract
The utility model discloses six rows of rapidly-dismounted type roller slewing bearings, and relates to a large-scale crane. The technical problem that the conventional large-scale crane slewing bearings cannot meet the two requirements on low-height and rapid dismounting at the same time is solved. The six rows of rapidly-dismounted type roller slewing bearings comprise six rows of roller slewing bearings, a base and connection pin shafts, wherein the six rows of roller slewing bearings are fixedly connected with upper structural components; and the base is fixedly connected with lower structural components. The six rows of rapidly-dismounted type roller slewing bearings are characterized in that an upper seat is arranged between the six rows of roller slewing bearings and the base; the six rows of roller slewing bearings are fixed with the upper seat by inner circle of bolts and outer circle of bolts which are axially arranged; the upper seat is connected with the base by a plurality of pin shafts which are circumferentially and radially arranged; the pin shafts are connected with a plug pin oil cylinder; and the base is clamped with a cylinder barrel of the oil cylinder by a baffle plate. After the pin shafts are arranged in place, the pin shafts are fixed with the base by the clamping plate; and the six rows of rapidly-dismounted type roller slewing bearings are suitable for large-scale cranes, and can meet the two requirements on low-height and rapid dismounting at the same time.
Description
Technical field
The utility model relates to goliath, particularly the pivoting support of heavy construction hoisting crane.
Background technology
Generally two kinds commonly used of the pivoting supports of heavy construction hoisting crane.A kind of structure is as shown in Figure 1: adopt three row's roller pivoting supports 1, the bottom arranges fast assembly and disassembly mechanism (comprise and connect bearing pin 2 and base 3).Pivoting support 1 is fixed by bolt and topside, and base 3 is fixed by bolt and bottom section, connects by bearing pin 2 between pivoting support and the base.Bearing pin 2 available hydraulic oil cylinders are inserted or are pulled out.The advantage of three row's roller pivoting supports is to realize fast assembling-disassembling, and its shortcoming is that the whole height of supporting is higher.Another kind of structure is as shown in Figure 2: be six row's roller pivoting supports.Its advantage is highly lower, is applicable to the strict occasion of requirement for height, and its shortcoming is relatively difficulty of dismounting.
In the middle of the existing heavy construction rubber tyre gantry crane design, usually use the pivoting support that diameter reaches 3 meters.To the load-carrying properties of pivoting support with highly all have higher requirements, and can fast assembling-disassembling.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of quickly dismantled six row's roller pivoting supports are provided, and solves the technical matters that existing heavy construction crane rotation supporting can not be satisfied low clearance and two requirements of fast assembling-disassembling simultaneously.
The utility model is achieved through the following technical solutions:
A kind of quickly dismantled six row's roller pivoting supports, comprise: six row's roller pivoting supports of captiveing joint with the upper junction member, the base of captiveing joint with the lower junction member, and connection bearing pin, it is characterized in that: between described six row's roller pivoting supports and described base, the seat of honour is set, described six row's roller pivoting supports are fixed by axial arranged bolt and the described seat of honour of inside and outside two circles, a plurality of described bearing pin of the described seat of honour by the border radial arrangement be connected base and connect; Described bearing pin is connected with the insert-pull pin oil cylinder, and with the cylinder barrel clamping of baffle plate with described base and described oil cylinder.
The utility model compared with prior art owing to adopt six row's roller pivoting supports, has reduced device height in the situation of same bearer ability; Owing to adopt fast assembly and disassembly mechanism, the dismounting efficient of upper unit and lower device improved greatly; Owing to adopt the hydraulic ram plug to connect bearing pin, reduced labor strength, increase work efficiency.The utility model is used for goliath, can satisfy simultaneously two requirements of low clearance and fast assembling-disassembling.
Description of drawings
Fig. 1 is the structural representation of a kind of crane rotation supporting of prior art;
Fig. 2 is the structural representation of another crane rotation supporting of prior art;
Fig. 3 is this practical new structural arrangement scheme drawing.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing
The specific embodiment
As shown in Figure 3, a kind of quickly dismantled six row's roller pivoting supports, comprise: six row's roller pivoting supports 4 of captiveing joint with the upper junction member, the base 3 of captiveing joint with the lower junction member, and connection bearing pin 2, it is characterized in that: between described six row's roller pivoting supports 4 and described base 3, the seat of honour 5 is set, described six row's roller pivoting supports 4 are fixing by inside and outside two circles axial arranged bolt and the described seat of honour 5, a plurality of described bearing pin 2 of the described seat of honour 5 by the border radial arrangement be connected base 3 and connect; Described bearing pin 2 is connected with insert-pull pin oil cylinder 6, and with baffle plate 7 with the cylinder barrel clamping of described base 3 with described oil cylinder 6.Described bearing pin 2 puts in place rear fixing with clamp 8.
Upper junction member of the present utility model, lower junction member split state: six row's roller pivoting supports 4, the seat of honour 5 and upper junction member all are bolted, and form upper unit; With connecting bearing pin 2 upper unit is installed on the base 3, and is connected with the lower junction member by bolt.Base 3 and lower junction member form lower device.
The utility model installation process:
1, by insert-pull pin oil cylinder 6 a plurality of connection bearing pins 2 of radial arrangement is extracted to end position.
2, upper unit is alignd with lower device, 2 to 3 connect bearing pin 2 location, guarantee the pin shaft hole alignment.
3, by insert-pull pin oil cylinder 6 a plurality of connection bearing pins 2 of radial arrangement are inserted into end position.And with clamp 8 bearing pin is blocked.
Unloading process: opposite with installation process.
