Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1, Fig. 2, a kind of for can the protective gear of Intelligent adjustment belt tension in belt transmission, comprise driving wheel 2, follower 3, adjustable slideway 1, described driving wheel 2 be placed on adjustable slideway 1, is connected between driving wheel 2 with follower 3 by belt 4.Described adjustable slideway 1 is connected with deceleration actuator 25, and the other end of deceleration actuator 25 is fixed by strong point scaffold 5; Deceleration actuator 25 is fixed with sensor, and deceleration actuator 25 is connected with mechanism control box 7 by deceleration actuator power line 9, and mechanism control box 7 is by testing signal transmission line 8 connecting sensor 6 simultaneously; Described mechanism control box 7 is connected with power control box 11 by control signal line 10, and power control box 11 connects power motor 12 by power motor cable 15.
Described mechanism control box 7 is provided with and is linked with control knob 13 and automatically controls to touch the button 14, be linked with control knob 13 when pressing, deceleration actuator 25 can drive adjustable slideway 1 to move to follower 3 direction, thus driving wheel 2 is moved to the position the shortest with follower 3 wheelbase, start automatic control knob 14 after hanging up belt, adjustable slideway 1 is pushed to tightening belt 4 and reaches predetermined tightness and self-locking by deceleration actuator 25.Power motor start button 16 is equipped with described power control box 11, for controlling the start and stop of power motor 12.
Be connected by bolt and nut between described deceleration actuator 25 with adjustable slideway 1, the end of deceleration actuator 25 is connected with linkage screw 26, linkage screw 26 the other end is connected with interlock nut 27, and described interlock nut 27 is fixed on adjustable slideway 1, such deceleration actuator 25 rotates, and namely drives adjustable slideway 1 to move by nut.
Described adjustable slideway 1 can be following structure: comprise catenating slider 19, free slide block 20, sliding sleeve 28 is fixed with respectively bottom described catenating slider 19 and free slide block 20 two ends, sliding sleeve 28 is set on slide rail A17 and slide rail B18, and the two ends of slide rail A17 and slide rail B18 are separately fixed on two square slide rails 29, make slide rail A17, slide rail B18 and root side's slide rail 29 jointly form a frame structure, and catenating slider 19 and free slide block 20 are fixed in this frame structure.Square slide rail 30 is slidably matched described two square sliding sleeves 29 with two respectively, and square slide rail 30 two ends are fixed on support girder steel 35.Side's sliding sleeve 29 is fixed with and regulates block 31, side's slide rail 30 is fixed with adjusting nut block 32, adjusting nut block 32 is connected with adjustment screw rod 33, the end of adjustment screw rod 33 is connected to and regulates on block 31, and adjust on screw rod 33 and be connected with standby jack panel 34, the position of screw rod 33 side of adjustment sliding sleeve 29 on square slide rail 30 can be adjusted like this by rotating, thus the lateral attitude of motivation of adjustment motor 12, and fixed by standby jack panel 34.
The middle part of described catenating slider 19 is fixed with interlock nut 27, and interlock nut 27 is connected with linkage screw 26, and linkage screw 26 direction is consistent with the movement direction of catenating slider 19, and the other end of linkage screw 26 is connected with deceleration actuator 25.Catenating slider 19 has mounting hole A21 and hole slot A23 is installed, free slide block 20 has mounting hole B22 and hole slot B24 is installed, and the distance between catenating slider 19 and free slide block 20 is adjustable, this makes it possible to the power motor 12 installing different size.And catenating slider 19 and the position of free slide block 20 on slide rail A17 and slide rail B18 adjustable, thus can the lengthwise position of motivation of adjustment motor 12.
Because adjustable slideway 1 realizes automatically regulating displacement according to the size of belt 4 tension force, and can self-locking, adding oil extractor be that non-frequent starting belongs to and runs machinery continuously for a long time, can realize No Load Start.Startup optimization after oil pumping unit more renews belt or maintenance down, is linked with control knob 13 as long as first start, and deceleration actuator 25 carries out replacing belt after adjustable slideway 1 being moved to power driving wheel 2 position the shortest with power follower 3 wheelbase; Restart automatic control knob 14, start the power motor start button 16 in power control box 11 simultaneously, driving force motor 12 rotates instantaneously because belt 4 does not have tension force and reaches rated speed, along with deceleration actuator 25 promotes adjustable slideway 1, the wheelbase of driving wheel 2 and follower 3 is increased, belt 4 tension force becomes large frictional force gradually and increases and drive belt 4 to rotate, and reaches the object that No Load Start power motor is energy-conservation.
In operation, when needing adjustment belt 4 tension force at every turn, the control signal transmitted by sensor 6 after testing signal transmssion line 8 is delivered to mechanism controls electronic box 7 and is compared, then go to control deceleration actuator 25 by deceleration actuator power line 9, adjustable slideway 1 is made to adjust to optimum position, make belt 4 keep optimal tension force, now deceleration actuator 25 stops also self-locking to wait for the control signal of next adjustment process.This function avoid deceleration actuator 25 repeatedly adjustable slideway 1 accelerated wear test that brings of continuous setup and belt 4 fluctuate within the specific limits all the time, and the power consumption of the deceleration actuator 25 produced when keeping.
When belt 4 life termination ruptures, sensor 6 records tension force signal and diminishes instantaneously, and mechanism control box 7 sends signal to power control box 11 by control signal line 10, and cut off motor cable 15 power supply, stopping powers for power motor 12 sends alarm signal simultaneously.Eliminate the belt 4 because unmanned nurse to rupture rear motor no-load running and the power consumption that brings.
