Description
Technical field
The utility model relates to a kind of adhesive tape automatic control fluid-pressure straining device.
Background technology
Adhesive tape automatic control fluid-pressure straining device is the characteristics according to China's coal-mine, metallurgical ore deposit, absorb the pioneering technology of world industry developed country, according to adhesive tape starting identical with tightening force under the normal operation needs that tension travel is different, and determine rational conveyor belt tension and design-calculated according to different place sealing-tape machine feeding density difference and same place feeding quantitative changeization.
Summary of the invention
The purpose of this utility model provide a kind of compact conformation, in light weight, can prolong the belt adhesive tape automatic control fluid-pressure straining device in service life.
The technical solution of the utility model is: a kind of adhesive tape automatic control fluid-pressure straining device, and this device mainly is made up of hoister system, hydraulic efficiency pressure system, electric-control system etc., and hoister system is by steel rope hydraulic wireline winch, assembly pulley, the dolly that moves about to be connected into system; Hydraulic efficiency pressure system is made up of hydraulic power unit, viscous clutch, drg etc.; Electric-control system is made up of electric cabinet, sensitive member etc.
This take-up device is installed in the belt feeder head, and when belt feeder started, the belt below the driving drum can be lax suddenly, skidding can appear in driving drum and belt, hydraulic pressure tension can be strained belt lax driving drum under rapidly, shortens belt feeder run up time, the service life of prolongation belt.
This take-up device is installed in the belt feeder tail, and when belt feeder started, driving drum upper strata belt can be opened very tightly suddenly, tension impact appears, oil cylinder piston bar in this fluid-pressure straining device can be shot out a part, eliminates tension impact, prolongs the service life of belt.
During the belt broken belt, automatically controlled can the output of take-up device cut off the belt feeder power supply signal.
Belt feeder is not worked or can easily fast be unclamped belt when keeping in repair.
The tensile force of this take-up device is easy to adjust, and can automatic compensation.
These series of products are divided into two kinds of coventional type and flame-proof types, be applicable to various levels such as aboveground, down-hole, go up fortune, downward belt conveyor workplace, especially for the longer tension travel of needs, the belt conveyer of big tightening force, its economic benefit is better, aboveground subsurface temperature Applicable scope-20 ~ 60 ℃
The beneficial effects of the utility model are: the adhesive tape of slack list was in time strained when (1) this device can make sealing-tape machine start, improved the starting characteristic of conveyer greatly, after adhesive tape startup and normal rotation, after mechanically hydraulic wireline winch being implemented braking and normal operation, mechanically hydraulic wireline winch is implemented braking, to keep the tension force of adhesive tape.Hydraulic Station quits work subsequently, and whole hydraulic efficiency pressure system is in passive state, thereby has avoided Hydraulic Elements to damage because of being in high pressure conditions for a long time, causes conveyor belt tension sharply to descend, and accidents such as adhesive tape skids, wearing and tearing take place.
Tension force was big when (2) usually conveyer started, when being about normal operation 1.5 times, use this device after, can avoid starting the skidding between cylinder and the adhesive tape, but energy efficient and prolong service life of adhesive tape also.
(3) this device maximum storage amount can reach 200m, can adapt to the tension requirement of 1080m long-distance transportation machine on the colliery.
(4) this device does not have hand change over valve, can relax rapidly or strains adhesive tape, is convenient to the maintenance of conveyer.
(5) shut down or when meeting accident power outage, can realize autobrake, and can guarantee reliably that adhesive tape is in tension.This device has fundamentally solved the problem that conveyer is regulated inharmonious appearance because of tightening force after using on the colliery, tension effect is better.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a control system functional-block diagram of the present utility model;
Fig. 3 is the fundamental diagram of hydraulic efficiency pressure system of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of adhesive tape automatic control fluid-pressure straining device, this device mainly is made up of hoister system, hydraulic efficiency pressure system, electric-control system 20 etc., and hoister system is by steel rope hydraulic wireline winch 18, assembly pulley, the dolly 19 that moves about to be connected into system; Hydraulic efficiency pressure system is made up of hydraulic power unit, viscous clutch, drg etc.; Electric-control system 20 is made up of electric cabinet, sensitive member etc.
The principle of work of control system when normal operation, records drive current by current sensor, after calculate theoretic tightening force F as shown in Figure 2
1, simultaneously record tightening force F on the winch cable by force gauge with this moment
2As feedback signal, compare the sizes of two values, adopt the electric current of Single-chip Controlling electricity liquid ratio relief valve, with the pressure P of controlled hydraulic system, promptly control the spacing h of oil film clutch (1 viscous speed regulating clutch coupling, 2 viscous braking power-transfer clutchs).Specifically can be divided into 3 kinds of situations: work as F
2＞F
1The time, control clutch 2 action increases power-transfer clutch spacing h, emits steel rope by the winch gear counter-rotating, reduce on the steel rope tightening force up to the theoretical value balance; Work as F
2＜F
1The time, control clutch 1 action reduces power-transfer clutch 1 spacing h, involves in steel rope by winch gear, increases the tightening force on the steel rope, finally reaches the force homeostasis of tension system; Work as F
2=F
1The time, winch is serving or put rope not.
During belt conveyer work, the maintenance adhesive tape must be at tension.The principle of work of hydraulic efficiency pressure system as shown in Figure 3.Start Oil pump electrical machinery 3, pressure oil enters the oil cylinder of power-transfer clutch 14 through thick, smart oil filter 2 and 5, hydraulic control one-way valve 8 and 3-position 4-way solenoid directional control valve 11.By the electric current of control box control electricity liquid ratio relief valve 6, thereby the pressure P of controlled hydraulic system work promotes clutch operating.Start winch motor at a slow speed, winch rotates at a slow speed, draws the dolly that moves about by steel rope.Tightening force unloading phase of conveyer provides starting current by Main Control Tank, sends into electromagnetic proportion relief valve 6, and through after a while, Main Control Tank provides the signal that allows conveyer to start; The action that the tightening force of stable operation stage comes control brake power-transfer clutch 15, power-transfer clutch 14, shuttle valve 16 and normally engaged brake 17 by Main Control Tank according to the signal of power and current sensor feedback.In the conveyer operational process, the pulling force of adhesive tape changes at any time, the proportional pressure control valve of this moment and each power-transfer clutch and drg in time respond action, can guarantee that the tightening force of conveyer when smooth operation keeps balance, thereby realize the dynamic tension of the adhesive tape of extension band type conveyor.
