Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model 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, in described housing 1, be provided with first suspension ring 12 and chute, tooth bar 11 is installed on the sidewall of described housing 1, on described housing 1 another sidewall, be 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, on described slide block 3, be provided with second suspension ring 31, swivel becket 32 and locating piece 33, described locating piece 33 slides and is arranged in described chute, between described first suspension ring 12 and described second suspension ring 31, be provided with spring 4, described slide block 3 is fixedly connected with circular dial plate 5, on described dial plate 5, be provided with graduated scale 51, 52He Yi contact, first contact 53, described first contact 52 and described second contact 53 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, on described rotor 21, be provided with pointer 22, on described pointer 22, be provided with contact 23, described housing 1 bottom is provided with fixed pulley 14 and line outlet 13, 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 portion 8, described battery portion 8 is connected with siren horn 82, in described battery portion 8, be provided with first contact 17 and second contact 16.
Described battery portion 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.
While 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, makes it above water.Like this, just realize traction function.
After Removable hook 7 is stressed, can strain cable 18.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.On slide block 3, have locating piece 33, and locating piece 33 slips are 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.Connected pointer 22 because of gear 2 again, and on slide block 3, connected 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.In the time of slide block 3 down sliding, extension spring 4, makes it to occur deformation.
The law of elasticity of Hooke is pointed out: spring is in the time that elastic deformation occurs, and elongation (or amount of compression) x of the elastic force F of spring and spring is directly proportional, i.e. F=-kx.Wherein k is the elasticity modulus of material, and it is determined by the character of material, and negative sign represents elastic force that spring produces and the opposite 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, be the displacement that equivalent occurs 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, can know the deformation quantity of spring 4.Finally, according to the elasticity modulus of spring 4, can calculate the pulling force that spring 4 is received.Because this device has used the structure of similar movable pulley, be that slide block 3 can be counted as a movable pulley with other structures that are arranged on slide block 3, so according to law of physics, movable pulley can be economized half power, so just can, under the stressing conditions of known movable pulley, calculate the power that cable 18 bears.
Excessive when the power that cable 18 bears, 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 excessive, need the warning of reporting to the police when stressed.
On housing 1, be 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.In battery portion 8, be 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 52He Yi contact, first contact 53 need be communicated with, provide electric energy with regard to quite satisfactory siren horn 82, it is given the alarm.
Be communicated with in order to realize 52He Yi contact, first contact 53, on pointer 22, be provided with contact 23, and 52He Yi contact, first contact 53 is arranged in same semicircle and their line through the center of circle of dial plate 5.Arrange like this, after pointer 22 rotates to an angle, will contact with 52He Yi contact, first contact 53, the contact 23 of making a comment or criticism on 22, just can be by 52He Yi contact, first contact 53 UNICOMs.Like this, siren horn 82 will be switched on, and just can report to the police.
On dial plate 5, be provided with graduated scale 51, can show very intuitively the power that cable bears.General by the position of 52He Yi contact, first contact 53, be arranged at 90% graduated scale position of power that cable maximum can bear.Like this, excessive when pulling force, after siren horn 82 is reported to the police, user also has enough leeway, adjusts.Maximized this device of having protected, and user's safety.
The utility model, low cost of manufacture simple in structure, can show the pulling force that cable bears, and has alarm function, in the time that pulling force is excessive, can give the alarm, and reminds user to take care.
