Abstract
A quick loading and unloading rigid coupler for a floating-point support drive ribbon conveyor is characterized in that an expansion sleeve is adopted to connect a semi-body of the coupler and a cylinder in the manner that a female surface is formed on the conical face of an expansion sleeve with the left semi-body and the right semi-body of the coupler; a key is adopted to connect a rotary shaft of a reducer and the expansion sleeve in the manner of respectively arranging a key groove on the corresponding position of the expansion sleeve and the rotary shaft of the reducer, and adopting the side face of the key arranged inside the key groove as a work face so as to lead the work face of the key to stick to the side face of the key groove to form loose coupling; interference fit is formed between the semi-body of the coupler and the rotary shaft of the reducer in virtue of the conical-face extrusion between an outer-ring of the expansion sleeve and the semi-body of the coupler. The quick loading and unloading rigid coupler has simple structure so as to greatly enhance the dismounting efficiency of coupler, shorten maintenance and shut-down time of equipments and enhance the manufacturing benefit.
Description
Technical field
The utility model relates to a kind of coupling, and the colliery transport system floating-point supporting type points driving for belt conveyor of more specifically saying so is with loading and unloading rigid coupling fast.
Background technique
Along with the comprehensive mechanical coal mining technology rapid development, coal mining, driving face advance very fast, require the haulage device in the gallery promptly to shorten flexibly or to extend, and tear open with minimizing and move number of times, save time, and improve coal mining throughput.In order to adapt to the production needs, existing floating-point supporting type points driving for belt conveyor, it is the special transportation device of exploiting field gallery and tunnelling, it has the transportation continuously of long distance, reliable and easily be automated characteristics by the time, become the main haulage device of down-hole raw coal.
The working principle of belt conveyor is that main head roll rotates under motoring, drives together operation continuously of cargo on the adhesive tape by the frictional force between head roll and the adhesive tape, after cargo is transported to the end, owing to the commutation of adhesive tape unloads.
Floating-point supporting type points driving for belt conveyor, its drive unit and base are bearing on the transmission frame by floating-point, with the head roll common bed, the drive unit volume is little, in light weight, stable and reliable for performance, particularly when roadway floor is out of shape, also can realize the smooth starting operation of conveyor, improve conveyor running life.
At present, routine is applied in the floating-point supporting type points driving for belt conveyor, adopt rigid coupling between head roll and the retarder, all adopts key connecting between rigid coupling and each shaft.Owing to install to adopt the heating assembling, when head roll or speed reducer needed repairing, owing to be subjected to condition restriction under the coal mine, dismounting was very difficult.
The model utility content
The utility model is for avoiding above-mentioned existing in prior technology deficiency, providing a kind of simple and feasible floating-point supporting type Belt Conveyors with loading and unloading rigid coupling fast, with the efficient that improves dismounting and install.
The utility model technical solution problem adopts following technological scheme:
The utility model floating-point supporting type points driving for belt conveyor is to adopt expansion set to connect between coupling halfbody and the cylinder with the quick structural feature of loading and unloading rigid coupling, and it is to form female surface with coupling left side halfbody and coupling right side halfbody on the conical surface of expansion set that described expansion set connects; Between retarder rotating shaft and expansion set, adopt key joint; Described key joint is on the corresponding position of described expansion set and retarder rotating shaft keyway to be set respectively, and the side that is placed on the key in the keyway is a working surface, and described key is to fit with its side working surface and the side of keyway to constitute loose the connection; By the outer ring of expansion set and the extruding of the conical surface between the coupling halfbody, between coupling halfbody and retarder rotating shaft, form interference fit.
The utility model floating-point supporting type points driving for belt conveyor also is between described coupling left side halfbody and the right halfbody of coupling positioning spigot to be set with the structural feature of loading and unloading rigid coupling fast, and on the position of symmetry clamping bolt is set.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model rigid coupling makes the main frame part make and install more and simplify.
2, in the utility model for the axle that expansion set is installed and the processing in hole, do not need as interference fit, to require high-precision manufacturing tolerances.
3, the utility model need not heat for the installation of expansion set, and cooling or pressurized equipment only need bolt moment is on request tightened and can be adjusted, and realize rigidity and accurate the connection easily, realize the transmission of moment of torsion.
4, the utility model simple structure can realize very short installation and removal.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 cylinder, 2 expansion sets, 3 positioning spigots, 31 coupling left side halfbody, the right halfbody of 32 coupling, 4 retarder rotating shafts, 5 keys, 6 clamping bolts.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings:
Embodiment
Referring to Fig. 1, in the present embodiment, between coupling halfbody and cylinder 1, adopt expansion set to connect, it is to form female surface with coupling left side halfbody 31 and the right halfbody 32 of coupling on the conical surface of expansion set 2 that expansion set connects, and produces frictional force realization transmitting torque by pressure; Between retarder rotating shaft 4 and expansion set 2, adopt key joint, be on the corresponding position of expansion set 1 and retarder rotating shaft 4, keyway to be set respectively, the side that is placed on the key 5 in the keyway is a working surface, key 5 is to fit with its side working surface and the side of keyway to constitute loose the connection, rely on the propagation of pressure moment of torsion between key and keyway, key 5 is a standard piece.
Before assembling, be Spielpassung between coupling endoporus and the retarder rotating shaft, the inner ring of back by expansion set is installed with the retarder rotating shaft and by the outer ring of expansion set and the extruding of the conical surface between the coupling, the formation interference fit, since transmitting torque.This form structure is simple, can greatly improve the dismounting efficient of coupling, shortens device maintenance dead time, has improved productivity effect.
In concrete the enforcement, between coupling left side halfbody 31 and the right halfbody 32 of coupling, positioning spigot 3 is set, and on the position of symmetry, clamping bolt 6 is set.
The tolerance in coupling hole changes Spielpassung into by interference fit, and the side of flat key is a working surface, and fitting with key slot side constitutes loose the connection.
