Description
Technical field
The invention belongs to Belt Conveying machinery engineering device technique field, is related to a kind of flexible roll stand frame of hydraulic control.
Background technology
Mineral industry and chemical industry, smelting industry need to carry out raw material in product processes flow is carried out at present
Logistics delivery processing, existing small belt conveyor length typically use regular length mounting means, i.e., object is from first to second
The distance on ground is fixed, when fed distance changes, when directly can not load onto conveyer and being conveyed, it is necessary to first use
Material is knocked conveyer by manpower or moveable loading machine, is conveyed again；This working method labor intensity is big, efficiency
It is low, it is not easy to realize continuous automatic transportation, it is extremely inconvenient for handling goods operation.Or belt conveyor length need to be transformed again
Size orders new belt conveyor again, has so both added the operation cost of company, while had influence on product again
Production cycle, influence progress.So there is an urgent need to the belt conveyor that can freely stretch, its critical component roller bracket needs
Effectively designed.
The content of the invention
The present invention provides the flexible roll stand frame of hydraulic control that a kind of automatically retractable, device structure are stable, simple to operate, solution
Certainly conventional apparatus telescopic effect is poor, the problem of can not automatically adjusting.
The present invention provides a kind of hydraulic control flexible roll stand frame, including frustum roll, the first expansion link, telescoping cylinder, second
Expansion link forms support, and two the first expansion links are located at support both ends；First expansion link includes first rotating shaft and two the first liquid
Depression bar, two the first hydraulic stem axle center are parallel to each other and perpendicular to first rotating shaft axle center, first rotating shaft and two the first hydraulic stems
It is fixedly connected；Telescoping cylinder includes two the first support members, the second rotating shaft, two hydraulic cylinders, the first support member and the second rotating shaft with
Hydraulic cylinder is fixedly mounted, the axis parallel of the first support member and the second rotating shaft and the axle center of vertical hydraulic cylinder；Second expansion link bag
Including the 3rd rotating shaft and two the second hydraulic stems, two the second hydraulic stem axle center are parallel to each other and perpendicular to the 3rd rotating shaft core, and
Three rotating shafts are fixedly connected with two the second hydraulic stems；First hydraulic stem and the second hydraulic stem coordinate with hydraulic cylinder sealing, and second
Hydraulic stem and the first hydraulic stem can be equal along hydraulic cylinder extension, first rotating shaft, the second rotating shaft, the 3rd rotating shaft in the presence of hydraulic pressure
Peace turns have a pair of frustum rolls, and frustum roll can be in first rotating shaft, the second rotating shaft, the 3rd axis of rotation, a pair of frustum rolls
Two frustum roller diameter smallest ends it is relative.
Two hydraulic cylinders of described telescoping cylinder provide hydraulic oil by hydraulic pump, control the second hydraulic stem and the first hydraulic stem
It is flexible.
The present invention realizes what hydraulic control roll stand frame freely stretched using the design of the flexible roll stand frame of assembled hydraulic cylinder formula
Function, the diversity of conveyer use occasion is helped increase, simplify the flexible operation of control, improve the sane of complete machine
Property, facilitates later maintenance, reduces factory's use cost, solves that conventional apparatus telescopic effect is poor, can not automatically adjust
Problem, there is the advantages of structural stability is high, and navigability is strong, and stepless retractable controls.

Embodiment
With reference to specific drawings and examples, the invention will be further described.
As shown in figure 1, the invention mainly comprises frustum roll 1, the first telescoping cylinder 3, three second of expansion link 2, four is stretched
Contracting bar 4 forms support, and two the first expansion links 2 are located at support both ends；First expansion link 2 includes first rotating shaft 21 and two first
Hydraulic stem 22, two axle center of the first hydraulic stem 22 are parallel to each other and perpendicular to the axle center of first rotating shaft 21, first rotating shaft 21 and two
First hydraulic stem 22 is fixedly connected；Telescoping cylinder 3 include two the first support members 32,31, two hydraulic cylinders 33 of the second rotating shaft, first
The rotating shaft 31 of support member 32 and second is fixedly mounted with hydraulic cylinder 33, and the axis parallel of the first support member 32 and the second rotating shaft 31 simultaneously hangs down
The axle center of straight hydraulic cylinder 33；Second expansion link 4 includes the 3rd rotating shaft 41 and two the second hydraulic stems 42, two the second hydraulic stems 42
Axle center is parallel to each other and is fixedly connected perpendicular to the axle center of the 3rd rotating shaft 41, the 3rd rotating shaft 41 with two the second hydraulic stems 42；First
The hydraulic stem 42 of hydraulic stem 22 and second seals with hydraulic cylinder 33 to be coordinated, and the second hydraulic stem 42 and the first hydraulic stem 22 can be in liquid
Flexible along hydraulic cylinder 33 in the presence of pressure, first rotating shaft 21, the second rotating shaft 31, the 3rd rotating shaft 41, which are pacified, turns have a pair of frustum rolls
1, frustum roll 1 can rotate around first rotating shaft 21, the second rotating shaft 31, the 3rd rotating shaft 41, two frustums in a pair of frustum rolls 1
The diameter smallest end of roll 1 is relative.
During work, start external motive device, drive the frustum roll 1 on the first expansion link 2 to rotate, frustum roll 1 is logical
Frictional force is crossed so that conveyer belt moves, carries out material conveying；During elongation, elongated distance A is determined, starts hydraulic pump, hydraulic pump is past
Four telescoping cylinders 3 inject pressure oil, and pressure oil promotes the first expansion link 2 and three the second expansion links 4 to release distance A；During shortening,
It is determined that reducing the distance B, start hydraulic pump, hydraulic pump injects pressure oil toward four telescoping cylinders 3, and pressure oil promotes the first expansion link 2
Retracted with three the second expansion links 4, until reducing the distance B, close hydraulic pump.
