Description of drawings
Fig. 1 is the left view of bearing cover holder device under installment state of a preferred embodiment of the utility model;
Fig. 2 is the front view of bearing cover holder device shown in Figure 1 under installment state;
Fig. 3 is the vertical view of bearing cover holder device shown in Figure 1 under installment state.
The specific embodiment
The main design thought of the utility model is to adopt two standing screws; The one of which end is separately fixed in the screwed hole on the bearing block horizontal level; Bearing cover is skidded off and hangs above that along this standing screw; Maintenance go back to slide the installation site on the bearing block with bearing cover along standing screw after finishing again, so just need not heavier bearing cover lifted to be placed on ground and could to begin to overhaul.The scope of application for the holder device that enlarges the utility model; Preferably; The cross bar of an adjustable length can be installed between two standing screws, in order to adapting to the bearing covers of different sizes, and install one at the cross bar middle part and can be against ground supporting leg; Be used for support section weight, adapt to the heavier bearing cover of weight.
Preferred bearing cover holder device of the utility model such as Fig. 1-shown in Figure 3 comprise horizontal clamping screw 2, supporting leg 3, vertically clamping screw 4, supporting leg extension bar 5, laterally hollow bushing 6, standing screw 7, adjustable cross bar 8 and hollow bushing 9 radially.Laterally hollow bushing 6 is the steel pipe of 25mm for internal diameter; Two identical external diameters are the steel pipe of 20mm--adjustable cross bar 8; Be inserted in the right ends of horizontal hollow bushing 6 respectively, and can laterally moving in the hollow bushing 6, thereby adjust the length that adjustable cross bar 8 stretches out the part of horizontal hollow bushing 6.On horizontal top, hollow bushing 6 left and right sides, symmetry is installed a horizontal clamping screw 2, but tightens horizontal clamping screw 2 stationary adjustable cross bars 8, and it can not arbitrarily be moved again.One of the outer end of adjustable cross bar 8 welding is hollow bushing 9 radially, and standing screw 7 can pass radially hollow bushing 9 and be on the same horizontal plane with horizontal hollow bushing 6.One end of standing screw 7 is provided with the end of thread 10, can be complementary with the bearing block screwed hole, and its external diameter can slide bearing cover 1 along standing screw 7 less than the bore of the bolt via hole on the bearing cover 1.Supporting leg 3 is the steel pipe of 20mm for external diameter, its upper end and the laterally center-side lower vertical welding of hollow bushing 6, and the lower end of supporting leg 3 is inserted the inside of supporting leg extension bar 5 and can inside be moved up and down, and supporting leg extension bar 5 is the steel pipe of 25mm for internal diameter.The top of supporting leg extension bar 5 is provided with vertical clamping screw 4, and when it was tightened, supporting leg 3 promptly was fixed, and can't continue in supporting leg extension bar 5, to move up and down.
Needs with bearing cover 1 when bearing block disassembles, at first two screws of the horizontal symmetrical on the bearing cover 1 are backed out, unclamp two horizontal clamping screws 2; Adjust the distance between two set bolts 7; Make the hollow end of hollow bushing 9 radially face the screwed hole of two horizontal levels respectively, select to be fit to the standing screw 7 of bearing block to be removed, insert in the hollow end of hollow bushing 9 radially; After adjustable cross bar 8 and standing screw 7 are vertical, tighten horizontal clamping screw 2; Then, the end of thread 10 is connected with the screwed hole of bearing block to be removed, unclamps vertical clamping screw 4; The length of adjustment supporting leg 3; Supporting leg extension bar 5 is contacted with ground or ground backing plate, and guarantee that supporting leg extension bar 5 is vertical with standing screw 7, tighten vertical clamping screw 4; Next; Remove on the bearing cover 1 behind all bolts; Use screwdriver that bearing cover 1 is prized along standing screw 7 directions gently, after treating bearing cover 1 and bearing block separating, both hands with bearing cover 1 along the standing screw 7 parallel length that are drawn out to enough maintenance; After Awaiting Overhaul finishes, both hands with bearing cover 1 along standing screw 7 parallel pushing back, install the bolt on the non-horizontal level after, standing screw 7 is disassembled from bearing block, first-class latter two bolt, operation is accomplished.
If bearing cover 1 weight of dismounting own is lighter, the weight of bearing cover 1 can be born by standing screw 7 fully, and supporting leg extension bar 5 can be against on the ground; If bearing cover 1 weight of dismounting own is heavier, bearing cover 1 can bend standing screw 7, and at this moment, supporting leg extension bar 5 can bear part weight after propping up ground, has avoided standing screw 7 to be bent the generation of situation.Supporting leg extension bar 5 also can connect a base (not shown), perhaps fills up a backing plate, is used to reduce the pressure to the ground generation.
After adopting the bearing cover holder device that the utility model describes, bearing cover can be supported with supporting leg by the standing screw of this device, need not it is lifted to be placed on the ground and can to accomplish service work, has avoided bearing cover to drop and has pounded the possibility of hurting sb.'s feelings; In addition, standing screw 7 can be changed according to different bearing blocks, and the standing screw of the left and right sides apart from scalable, the height of support is scalable also, has enlarged the range of application of the utility model.
The foregoing description only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also should belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each claim.
