Abstract
The utility model discloses a home-made bearing detachment fixture which comprises a steel frame, a jack and a bearing support seat. The steel frame is formed by welding two vertical columns, a cross beam and a bottom beam, wherein a steel tube is fixed at the centre of the bottom beam; a steel block is fixedly connected to the top of the steel tube; a circular hole which is concentric with the steel tube is formed at the centre of the steel plate; the diameter of the circular hole is smaller than the outer diameter of the detached bearing and greater than the inner diameter of the detached bearing; the steel tube and the steel plate form the bearing support seat; the jack is arranged between the bearing support seat and the cross beam; and the press head of the jack is downward and right opposite to a cutting spindle at the centre of the detached bearing. The home-made bearing detachment fixture disclosed by the utility model is simple in structure, convenient to operate, and capable of intactly detaching the bearing on the cutting spindle of a tunnelling machine, thus enabling the bearing to be reutilized, avoiding unnecessary cost waste, and further shortening the construction period of major overhaul for the tunnelling machine.
Description
Technical field
The utility model belongs to the machine tool technical field, relates to a kind of special tooling of dismantling bearing.
Background technology
In development machine overhaul process, a lot of problems can occur, often damage such as the cut macro-axis that supports whole cutting units rotation, particularly the spline position of cut macro-axis.Generally speaking, after if the cut macro-axis is scrapped, top bearing also will and then replace, because what bearing and cut macro-axis adopted when assembling is hot charge practice, namely strike by heating and pound into, the method that need to adopt again heating firmly to pound when removing again, the performance of bearing is damaged thus, is difficult for re-using.Certainly in the practical operation, also can directly bearing be sliced off in order to save the working time, so an intact bearing has also just been scrapped, and producing unnecessary waste has increased construction cost greatly.When running into all situations described above, wanting to continue to use original bearing, very little probability under the bearing removal in the situation of not damaging bearing performance, so adopt what kind of method to disassemble bearing is intact, is to be badly in need of the problem that will solve.
The utility model content
The purpose of this utility model provides a kind of self-control dismounting bearing frock, how to solve the technical problem that disassembles from macro-axis that bearing performance is intact.
For achieving the above object, the utility model adopts following technical scheme:
A kind of self-control dismounting bearing frock, it comprises steel frame, jack and bearing spider, described steel frame is by two root posts, crossbeam and a foundation beam are welded, the center of described bottom girder is fixedly connected with a steel pipe, the top of described steel pipe is fixedly connected with a block plate, the center of described steel plate has a circular hole concentric with steel pipe, the diameter of described circular hole is less than the external diameter of split bearing, greater than split bearing bore diameter, described steel pipe and steel plate form bearing spider, be provided with jack between described bearing spider and the crossbeam, the pressure head of described jack is downwards over against the cut macro-axis of split bearing centre.
The diameter of described steel plate is greater than steel pipe, and the angle of steel plate bottom surface and steel pipe is connected with the reinforcement gusset.
Described column, crossbeam and bottom girder are I-steel or H shaped steel.
Described crossbeam vertically is connected with several gussets between top flange and lower flange.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model can provide a kind of special tooling of intact dismounting bearing, the split bearing that is installed on the cut macro-axis can be taken out smoothly.Whole tool structure is simple, and is easy to use, taken into full account split bearing place cut macro-axis the position, with assemble method and the split bearing self performance thereof of cut macro-axis.
The utility model is mainly used in the overhaul process of development machine, utilize the strength of jack and the booster action of steel frame, split bearing is successfully disassembled from the cut macro-axis, jack all heads into the cut macro-axis in the steel pipe, simultaneously harmless having stayed on the steel plate of split bearing on the cut macro-axis.So that split bearing can utilize again after the overhaul, avoided unnecessary cost waste, further shortened the duration of development machine overhaul.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing and example.
Fig. 1 is the utility model structural representation.
Reference numeral: 1-column, 2-crossbeam, 3-gusset, 4-bottom girder, 5-jack, 6-cut macro-axis, the split bearing of 7-, 8-steel pipe, 9-steel plate, 10-strengthen gusset.
The specific embodiment
Embodiment is referring to shown in Figure 1, this self-control dismounting bearing frock, and it comprises steel frame, jack and bearing spider, and described steel frame is welded by two root posts 1, crossbeam 2 and a foundation beam 4, and described column, crossbeam and bottom girder are I-steel or H shaped steel.The center of described bottom girder 4 is fixedly connected with a steel pipe 8, the top of described steel pipe 8 is fixedly connected with a block plate 9, the center of described steel plate 9 has a circular hole concentric with steel pipe, the diameter of described circular hole is less than the external diameter of split bearing 7, greater than split bearing bore diameter, described steel pipe 8 and steel plate 9 form bearing spider, and the angle of steel plate 9 bottom surfaces and steel pipe 8 is connected with strengthens gusset 10.Be provided with jack between described bearing spider and the crossbeam, the pressure head of described jack 5 is downwards over against the cut macro-axis at split bearing 7 centers.Described crossbeam 2 vertically is connected with several gussets 3 between top flange and lower flange.
Packing engineering of the present utility model and the course of work: at first, select the I-steel of I25 as column, crossbeam and bottom girder, with a crossbeam, a foundation beam and the two root posts steel frame that is welded, and between crossbeam top flange and lower flange, vertically be connected with several gussets, strengthen supporting.
Then choose the satisfactory steel pipe of diameter, adopting diameter in the present embodiment is the steel pipe of φ 273, with model of welded top of steel pipe steel plate that is δ 16, as flange, the angle of steel plate bottom surface and steel pipe is connected with strengthens gusset 10, and having a circular hole concentric with steel pipe at the steel plate center, the diameter of described circular hole is less than the external diameter of split bearing, greater than split bearing bore diameter.Subsequently, will put steel pipe into the part of the cut macro-axis of split bearing, the split bearing on the cut macro-axis just in time is seated on the steel plate.
At last, the assembly fixed in position of cut macro-axis and steel pipe between the crossbeam and bottom girder of steel frame, is fixedly connected with the bottom of steel pipe with the bottom girder of steel frame; Jack is placed on the macro-axis of bearing spider simultaneously, the workmen is auxiliary operation aside, and jack is withstood crossbeam, and after placing, 100 tons the pressure head of jack of weighing is downwards over against the cut macro-axis of split bearing centre.The utility model utilizes the strength of jack and the supplemental support effect of steel frame, and jack all heads into the cut macro-axis in the steel pipe, and meanwhile, split bearing is intact unloading from the cut macro-axis just.
The above embodiment; it only is the more representational specific embodiment of the utility model; but the utility model institute resist technology scheme is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can from direct all changes or the replacement of deriving or expecting easily of the disclosed content of the utility model, all should be encompassed within the protection domain of the present utility model.
