Description
Technical field
The present invention relates to a kind of distance-limiting type low speed holdback.
Background technology
At present the holdback that adopts of China's upper conveying belt type conveyer mainly contains two kinds of contactless holdback and contact holdbacks; If above-mentioned two kinds of holdbacks are applied in drive on the upper conveying belt type conveyer more; A holdback normally all to be installed on every cover actuating device, for this reason, require zero on each actuating device, parts stand under load when the complete machine check in a basic balance; Check moment on just every cover holdback is equal basically, and in real work, exists problems:
1, when belt conveyer heavy duty parking or heavily loaded emergency braking; The check moment great majority that holdback bore all can not be realized equilibrium; Even the load concentration that the overwhelming majority can occur is therein on holdback, and holdback that causes this actuating device and load increases relevant zero, parts possibly cause that these are zero, parts overload and damaging; Thereby make the belt conveyer can not the failure-free stopping brake even cause driving, produce very serious consequence.
2, on the host design of belt conveyer; Generally select the increase of the check moment coefficient on the actuating device for use the high standard holdback when selecting holdback for use; It can be satisfied bear the required check moment of whole piece belt conveyer separately; So both increased the cost of equipment of complete machine, possibly cause again other zero, the parts overload, thereby reduced complete machine check reliability.
Summary of the invention
The purpose of this invention is to provide a kind of distance-limiting type low speed holdback.
The objective of the invention is to realize through following technical scheme:
Distance-limiting type low speed holdback of the present invention comprises initiatively hub, pressing plate, right supporting disk, movable friction plate group, static friction sheet group, driven hub, dish spring, dish spring briquetting, adjusting screw(rod), roller, roller cover, foreign steamer, left supporting disk, stay bearing plate and oil sealing dish.Initiatively hub and pressing plate are through bolted connection, and the movable friction plate group is through the external tooth setting-in of internal tooth with the active hub, and static friction sheet group is through the internal tooth setting-in of external tooth and driven hub; Driven hub and right supporting disk are through bolted connection, and driven hub and left supporting disk are through bolted connection, and right supporting disk is provided with tapped bore; Adjusting screw(rod) and right supporting disk are through being threaded, and adjusting screw(rod) is located at dish spring briquetting right side, and dish spring briquetting is located at dish spring right side; The dish spring is located at static friction sheet group right side; Roller is located between driven hub and the foreign steamer, and the axle of roller is located in the roller cover, passes through bolted connection between the roller cover; Stay bearing plate and foreign steamer are through bolted connection, and stay bearing plate and oil sealing dish pass through bolted connection.
Technical scheme by the invention described above provides can be found out; Distance-limiting type low speed holdback of the present invention, compactness rational in infrastructure is convenient to control; Safe and reliable; The check moment of every cover actuating device is limited in the particular range, thereby reaches the purpose that holdback all carries work, improve the operating safety factor of belt conveyer.
Description of drawings
Fig. 1 is a distance-limiting type low speed holdback structural representation;
Fig. 2 is the left TV structure scheme drawing of distance-limiting type low speed holdback;
Fig. 3 is adjusting screw(rod), dish spring briquetting, dish spring connection scheme drawing.
The specific embodiment
Distance-limiting type low speed holdback of the present invention; The specific embodiment that it is preferable such as Fig. 1, Fig. 2, shown in Figure 3, distance-limiting type low speed holdback comprise initiatively hub 1, pressing plate 2, right supporting disk 3, movable friction plate group 4, static friction sheet group 5, driven hub 6, dish spring 7, dish spring briquetting 8, adjusting screw(rod) 9, roller 10, roller cover 11, foreign steamer 12, left supporting disk 13, stay bearing plate 14 and oil sealing dish 15.
Initiatively hub 1 passes through bolted connection with pressing plate 2; Movable friction plate group 4 is through the external tooth setting-in of internal tooth with active hub 1; Static friction sheet group 5 is through the internal tooth setting-in of external tooth and driven hub 6, and driven hub 6 is passed through bolted connection with right supporting disk 3, and driven hub 6 is passed through bolted connection with left supporting disk 13.
Right supporting disk 3 is provided with tapped bore, and adjusting screw(rod) 9 and right supporting disk 3 are through being threaded, and adjusting screw(rod) 9 is located at dish spring briquetting 8 right sides, and dish spring briquetting 8 is located at dish spring 7 right sides, and dish spring 7 is located at static friction sheet group 5 right sides.
Distance-limiting type low speed holdback of the present invention has following inventive point:
Distance-limiting type low speed holdback is provided with adjusting screw(rod), can regulate dish spring stroke according to actual conditions, and the wearing and tearing between compensation movable friction plate group and the static friction sheet group remain in the setting range check moment of holdback;
Distance-limiting type low speed holdback comes transfer torque through the friction force between movable friction plate group and the static friction sheet group, can actv. the highest moment of torsion of restriction distance-limiting type low speed holdback, improved safety factor.
Further specify below in conjunction with the principle of work of accompanying drawing distance-limiting type low speed holdback:
Distance-limiting type low speed holdback is when belt conveyer normally moves, and initiatively hub drives the motion of movable friction plate group, under the effect of belleville spring; Movable friction plate group and static friction sheet group fit together closely; Rely on the friction force between movable friction plate group and the static friction sheet group to come transfer torque, make static friction sheet group follow the movable friction plate group and rotate, static friction sheet group drives driven hub and rotates together; Roller squints under the drive of driven hub, makes the holdback normal operation.
In the time will reversing under the effect of belt conveyer at material; Roller recovers original position under the effect of torsion spring; Thereby make roller tightly block driven hub, make driven hub keep quiescence, promptly static friction sheet group is static; If check moment that holdback bore is during less than the setting value of holdback, belt conveyer is realized check; If the holdback check moment of bearing is during greater than the setting value of holdback; During promptly greater than the friction moment between movable friction plate group and the static friction sheet group; Relative slippage takes place in movable friction plate group and static friction sheet group; To unload to the holdback on other actuating device above that part of moment branch of setting value and share, actv. has prevented the overload of holdback, thereby has improved the safety factor of belt conveyer.
The invention has the beneficial effects as follows:
Compact conformation, reliability height are convenient to centralized control;
The check moment of every cover actuating device is limited in the particular range, makes holdback can all carry work;
Improved the operating safety factor of belt conveyer.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
