Abstract
The utility model provides a device for demounting a large coupler. The device comprises a front baffle and a rear baffle, wherein the front baffle and the rear baffle are fixedly connected through a stud. A semicircular groove for buckling the coupler is formed in the lower edge of the front baffle, and a hydraulic jack is clamped between the front baffle and the rear baffle. The large coupler can be easily demounted through large axial thrust of the hydraulic jack, demounting efficiency is greatly improved, maintenance time is shortened, labor intensity of workers is relieved, and work efficiency is saved.
Description
Technical field
The utility model relates to a kind of large-scale detaching device for coupling.
Background technology
Coal Mine Electromechanical Equipment is used the more of large-scale shaft coupling at present, such as the supporting connection that large-size machine, large-scale belt feeder master rotor, decelerator etc. are all used large-scale shaft coupling to carry out different main computer boxes is used.By matching requirements, shaft coupling is assembled, make shaft coupling transmitting torque safely and reliably.While needing repairing due to the fault of equipment or shaft coupling faults itself, dismounting coupling need be become to parts.During dismounting couplers, generally first pull down connecting bolt, from axle, pull down wheel hub again, the wheel hub connecting for key, general employing with the wheel hub appearance and size tripod that matches draws horse or four pin to draw horse to dismantle, but for the larger wheel hub of interference, its dismounting exists and relatively to require great effort, take a lot of work and time-consuming shortcoming.And existing detaching device for coupling intensity is lower, fragile, and dismantle large-scale shaft coupling comparatively difficulty, work efficiency is low, and labor strength is larger.
Utility model content
The utility model is difficult to a difficult problem for dismounting in order to solve large-scale shaft coupling interference fit, a kind of large-scale detaching device for coupling of easy to use, quick-detachment is provided.
In order to reach above-mentioned effect, the utility model provides a kind of large-scale detaching device for coupling, comprise the front apron and the backboard that by stud, are fixedly connected with, the lower limb of described front apron offers the semi-circular recesses for buckle shaft coupling, between described front apron and backboard, is arranged with hydraulic jack.
Further, in order to increase the intensity of front apron and backboard, can bear the active force of hydraulic jack, on described front apron and backboard, all be installed with reinforcement.
Further, described front apron and backboard upper left, part on the right side and do not offer described in the bolt hole that wears stud the two ends of stud and be respectively equipped with nut and be fixed.
Further, for the thrust that hydraulic jack is produced is more balanced, the center of circle of the bolt hole on described front apron and the center of circle of semi-circular recesses are in the same horizontal line.
During use, first by stud, front apron and backboard are coupled together, again the semi-circular recesses of front apron is stuck on shaft coupling, between front apron and backboard, 50T hydraulic jack is placed in position, the front end of hydraulic jack withstands on the axle of cylinder or decelerator, and makes the axis of hydraulic jack and the axis of shaft coupling (or drum shaft) on same straight line; Finally, in the fixedly top nut of two ends of stud, hydraulic jack is fixed between front apron and backboard, is also about to this device and is fixed on shaft coupling.Then to shaft coupling homogeneous heating, shake the handgrip of hydraulic jack, shaft coupling expanded by heating, and move and separate with main shaft under the thrust of 50T hydraulic jack item, reach the object of dismounting couplers.
The utility model utilizes the axial thrust that hydraulic jack is larger can dismantle easily large-scale shaft coupling, and has greatly improved removal efficiency, and shortened maintenance time, reduces labor strength, saves work efficiency.In addition, this apparatus structure is simple, can Assembling, and easy to use and processing cost is low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of front apron in the utility model;
In figure: 1, front apron; 1-1, reinforcement; 1-2, semi-circular recesses; 1-3, bolt hole; 2, stud; 3, backboard; 4, nut; 5, hydraulic jack.
The specific embodiment
As shown in Figure 1, 2, a kind of large-scale detaching device for coupling, comprise the front apron 1 and backboard 3 that by stud 2, are fixedly connected with, the lower limb of described front apron 1 offers the semi-circular recesses 1-2 for buckle shaft coupling, between described front apron 1 and backboard 3, is arranged with hydraulic jack item 5.In order to increase the intensity of front apron 1 and backboard 3, can bear the active force of hydraulic jack, on front apron 1 and backboard 3, be all installed with reinforcement 1 one 1.
Further, described front apron 1 is upper left with backboard 3, part on the right side and do not offer the bolt hole 1 one 3 that wears stud 2, and the two ends of stud 2 is respectively equipped with nut 4 and is fixed.For the thrust that hydraulic jack is produced is more balanced, the center of circle of the bolt hole 1-3 on described front apron 1 and the center of circle of semi-circular recesses 1-2 are in the same horizontal line.
Above embodiment is not limited only to protection domain of the present utility model, all based on basic thought of the present utility model, modify or change all belong to protection domain of the present utility model.
