Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: as shown in Figures 1 to 4, a kind of tractor of overload warning, comprise housing 1, fixed hook 6 and Removable hook 7, first suspension ring 12 and chute is provided with in described housing 1, the sidewall of described housing 1 is provided with tooth bar 11, described another sidewall of housing 1 is provided with wire collecting part 15, described tooth bar 1 engagement fit is connected with gear 2, described gear 2 rotates and is arranged on slide block 3, described slide block 3 is provided with second suspension ring 31, swivel becket 32 and locating piece 33, described locating piece 33 slides and is arranged in described chute, spring 4 is provided with between described first suspension ring 12 and described second suspension ring 31, described slide block 3 is fixedly connected with circular dial plate 5, described dial plate 5 is provided with graduated scale 51, first contact 52 and second contact 53, described first contact 52 and described second contact 53 to be arranged in same semicircle and their line through the center of circle of described dial plate 5, described first contact 52 is connected with first connection lead 521, described second contact 53 is connected with second connection lead 531, described gear 2 is fixedly connected with rotor 21, described rotor 21 is provided with pointer 22, described pointer 22 is provided with contact 23, fixed pulley 14 and line outlet 13 is provided with bottom described housing 1, described wire collecting part 15 is connected with cable 18, described cable 18 is connected with described Removable hook 7, described fixed pulley 14 and described slide block 3, described fixed hook 6 is arranged on described housing 1, described housing 1 is provided with battery unit 8, described battery unit 8 is connected with siren horn 82, described battery unit 8 is provided with first contact 17 and second contact 16.
Described battery unit 8 is connected with switch 81, and described first contact 17 is connected with described first connection lead 521, and described second contact 16 is connected with described second connection lead 531.
When using this device, generally fixed hook 6 is installed on vehicle initiatively.Then, Removable hook 7 is pulled out, and be connected with stranded vehicle.After connecting, just can starting switch 81, siren horn 82 is with regard to dead work.Then, active vehicle starts, and advancing forward slowly, under the help of rope, just can pull stranded vehicle, make it above water.Like this, just traction function is achieved.
After Removable hook 7 is stressed, cable 18 can be strained.After cable 18 is tightened up, receive the application force of pulling force effect and cable 18 self.At this moment, slide block 3 can be pulled.Slide block 3 has locating piece 33, and locating piece 33 slip is arranged in the chute of housing 1, like this, slide block 3 just can not rotate, but can slide up and down.After slide block 3 slides, gear 2 also can move thereupon.Because gear 2 and tooth bar 11 mesh together, so gear 2 can rotate.Again because gear 2 is connected to pointer 22, and slide block 3 is connected to dial plate 5, gear 2 rotates, and slide block 3 does not turn, so pointer 22 will rotate on dial plate 5.Be provided with spring 4, and by spring 4, slide block 3 be connected with housing 1.When slide block 3 slide downward, extension spring 4, makes it deformation occurs.
The law of elasticity of Hooke is pointed out: spring is when elastic deformation occurs, and the elastic force F of spring and elongation (or amount of compression) x of spring is directly proportional, i.e. F=-kx.Wherein k is the elasticity modulus of material, and it determined by the character of material, and negative sign represents that the elastic force that spring produces is contrary with the direction of its elongation (or compression).
The displacement that the deformation of this device spring 3 can be occurred by slide block 3 is determined.Slide block 3 is subjected to displacement, namely there is the displacement of equivalent in gear 2, due to rack and pinion engagement routing motion, then the diameter of known gears 2, the angle that can rotate according to pointer 12 thus calculates the displacement of slide block 3 exactly, namely can be aware of the deformation quantity of spring 4.Finally, according to the elasticity modulus of spring 4, the pulling force that spring 4 receives can be calculated.Because this device employs the structure of similar movable pulley, namely slide block 3 and other structures be arranged on slide block 3 can be counted as a movable pulley, so according to law of physics, movable pulley can economize half power, this makes it possible to, under the stressing conditions of known movable pulley, calculate the power that cable 18 bears.
The power of bearing when cable 18 is excessive, and when exceeding the scope that it can bear, cable 18 just has the potential danger of fracture.Therefore, the stressed needs of cable 18 are monitored, and, when stressed excessive time, need warning of reporting to the police.
Housing 1 is provided with power supply unit 8 and siren horn 82.Siren horn 82 can send hydropac, and power supply unit 8 can provide required electric energy for siren horn 82.Battery unit 8 is provided with first contact 17 and second contact 16, first contact 17 is connected with first connection lead 521, second contact 16 is connected with second connection lead 53, first contact 52 is connected with first connection lead 521, second contact 53 is connected with second connection lead 531, arranges like this, only first contact 52 need be communicated with second contact 53, there is provided electric energy with regard to quite satisfactory siren horn 82, make it give the alarm.
Be communicated with second contact 53 to realize first contact 52, pointer 22 be provided with contact 23, and first contact 52 and second contact 53 to be arranged in same semicircle and their line through the center of circle of dial plate 5.Such setting, after pointer 22 rotates to an angle, will contact with second contact 53 with first contact 52, the contact 23 of making a comment or criticism on 22, just can by first contact 52 and second contact 53 UNICOM.Like this, siren horn 82 will be energized, and just can report to the police.
Dial plate 5 is provided with graduated scale 51, the power that cable bears can be shown very intuitively.Generally by the position of first contact 52 and second contact 53, be arranged at the graduated scale position of 90% of the maximum power that can bear of cable.Like this, when pulling force is excessive, after siren horn 82 is reported to the police, user also has enough leeway, adjusts.Maximizedly protect this device, and the safety of user.
The present invention, the simple low cost of manufacture of structure, can show the pulling force that cable bears, and have alarm function, when pulling force is excessive time, can give the alarm, and reminds user to take care.
