Specific embodiment
For the ease of understanding the present invention, the present invention will be described more fully below.But the present invention can be with perhaps
Mostly different form is realized, however it is not limited to embodiment described herein.On the contrary, the purpose for providing these embodiments is to make
To the understanding more thorough and comprehensive of the disclosure.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention
The normally understood meaning of technical staff is identical.It is intended merely to describe in the term used in the description of back splint battery herein
The purpose of specific embodiment, it is not intended that in the limitation present invention.Term as used herein " and/or " including one or more
The arbitrary and all combination of relevant Listed Items.
It please refers to Fig.1 to Fig. 5, the drag conveyor of the better embodiment for the present invention, including the first power transmission
Equipment 100, the second power transmitting apparatus 200 and the chain of the first power transmitting apparatus 100 of connection and the second power transmitting apparatus 200
Item 300.Chain 300 is equipped with block device 350 to assist tight chain.In the present embodiment, the first power transmitting apparatus 100 and second
The structure of power transmitting apparatus 200 is identical, wherein the first power transmitting apparatus 100 is as the second power transmitting apparatus of head 200
As tail or the first power transmitting apparatus 100 head is used as the second power transmitting apparatus of tail 200.
First power transmitting apparatus 100 includes variable-frequency motor 40, retarder 50 and connection variable-frequency motor 40 and retarder 50
Chain tightener 60.
Chain tightener 60 includes housing 61, the normally engaged brake 62 for connecting housing 61, clutch 63, connection variable-frequency motor 40
The first shaft coupling 64 of output shaft, the second shaft coupling 65 of input shaft of the connection retarder 50, connection clutch 63
The hydraulicdirectional control valve 67 of handle 66 and the connection normally engaged brake 62.The first shaft coupling 64 connects with second shaft coupling 65
It connects.The clutch 63 is set in the second shaft coupling 65 and between second shaft coupling 65 and normally engaged brake 62.
The external splines of the clutch 63 coordinates with the internal spline of normally engaged brake 62, always in meshing state.
Specifically, referring to Fig. 4 and Fig. 5, housing 61 should be used for through slot 610 described in confession equipped with through slot 610
Handle 66 is worn.Through axially extending one fixed width of the slot 610 along second shaft coupling 65, have so as to provide space for handle 66
Along the axial stroke of second shaft coupling 65.
In the present embodiment, normally engaged brake 62 is high pressure and large torque normally engaged brake；The hydraulicdirectional control valve 67 is two
Position and four-way reversing valve, for connecting extraneous hydraulic power source and the normally engaged brake 62, by the opening to normally engaged brake 62 or
Person's liquid that breaks realizes control to normally engaged brake 62.Clutch 63 is set in circular, has internal spline and outer flower-key（Figure is not
Mark）.Clutch 63 is extended with flange end close to one end of first shaft coupling 64, so that the handle 66 is clamped.
When drag conveyor works normally, internal spline and the second shaft coupling 65 of clutch 63 are in disengaged condition, become
Frequency motor 40 is by the linkage driving retarder 50 of first shaft coupling 64 and second shaft coupling 65, so as to be provided for drag conveyor
Power；The normally engaged brake 62 and clutch 63 are not involved in work at this time.
When drag conveyor needs tight chain, operator is by handle 66 along clutch 63 axially from normally engaged brake 62
Towards the outside Slideslip in direction of first shaft coupling 64, the internal spline of clutch 63 is engaged with the external splines of second shaft coupling 65,
So as to which normally engaged brake 62 is connect with second shaft coupling 65；Hydraulicdirectional control valve 67 is opened, normally engaged brake 62 is made to be in open shape
State, at this time variable-frequency motor 40 work under low frequency state, carry out tight chain.
After chain 300 is tensioned, hydraulicdirectional control valve 67 breaks liquid, and normally engaged brake 62 unloads liquid, in on-position, then carries out
Cutter chain simultaneously connects chain；Hydraulicdirectional control valve 67 is opened, is inverted under 40 low frequency state of variable-frequency motor, completes tight chain；Finally, hydraulic pressure changes
Break liquid to valve 67, normally engaged brake 62 unloads liquid closing；Handle 66 pushes clutch 63 along the axial from the first shaft coupling of clutch 63
The inside Slideslip in direction of device 64 towards normally engaged brake 62 disengages, and completes entire tight chain action.
The drag conveyor of the present invention coordinates variable-frequency motor 40 and retarder 50 by chain tightener 60 so that tight chain mistake
Journey is reliable, easy to operate, greatly improves working efficiency.
Embodiment described above only expresses one embodiment of the present invention, and description is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
