Detailed description of the invention
Referring to figs. 1 through Fig. 4, that show the concrete structure of the preferred embodiment of the utility model.The constructional feature of each element of the utility model will be described in detail below, if and when being described to direction (upper and lower, left and right, before and after), be with the structure shown in Fig. 1 for reference describes, but actual user of the present utility model is to not limiting to so.
The utility model provides a kind of trailer coupling for collecting and sending conveyer, comprise base 1, friction mechanism, chain-wheel mechanism and ratchet device, the sprocket wheel 23 that described chain-wheel mechanism comprises sprocket wheel swing arm 21, is contained in the tween drive shaft 22 in described sprocket wheel swing arm 21 and is contained on described tween drive shaft 22, described tween drive shaft 22 is stepped shaft, tween drive shaft 22 is fixed by described sprocket wheel swing arm 21, and described sprocket wheel 23 is by sprocket wheel swing arm 21 and the installation base clamping being contained in the bearing on described stepped shaft.
Described friction mechanism comprise to be positioned on the left of described sprocket wheel 23 and with the friction lining 31 of described sprocket wheel 23 synchronous axial system, can with the friction pair part 32 of described friction lining 31 frictional fit and the left side resilient mounting that described friction pair part 32 is exerted a force to the right, described left side resilient mounting comprises by left-to-right left side nut 33, left side spring perch 34, friction lining spring 35 and the friction lining spring perch 36 be contained in successively on described tween drive shaft 22, is adjusted friction lining spring 35 deformation size by adjustment left side nut 33 thus is controlled friction lining 31 and friction pair part 32 contact force size.
Described ratchet device comprises pawl swinging arm 41, the ratchet 42 be contained on described pawl swinging arm 41, be contained on described tween drive shaft 22 and the ratchet 43 be positioned on the right side of described sprocket wheel 23 and the right side resilient mounting exerted a force to the left to described ratchet 43, and described right side resilient mounting comprises by left-to-right clutch spring holder 44, clutch spring 45, right side spring perch 46 and the right side nut 47 be contained in successively on described tween drive shaft 22.Adjust clutch spring 45 deformation size by adjustment right side nut 47 thus control ratchet 43 and sprocket wheel 23 contact force size.
Described sprocket wheel swing arm 21 and pawl swinging arm 41 are all contained in rotating shaft 5, and rotating shaft 5 is arranged on base 1 by bearing, pad, nut.Described sprocket wheel swing arm 21 and pawl swinging arm 41 are all equipped with the elastic reset part resetted around described rotating shaft 5, described elastic reset part comprises and is contained in apical axis 61 in the middle part of described sprocket wheel swing arm 21 and pawl swinging arm 41 respectively, is contained in the reset jacking block 62 on each described apical axis 61 and is contained in the Compress Spring 63 on a described reset jacking block 62, and described Compress Spring 63 is contained in the blind hole of described base 1.Described ratchet 43 and sprocket wheel 23 are provided with driving cog, and described sprocket wheel 23 is rotated by described driving cog driving pawl 43 and produces the axial force that ratchet 43 is separated to the right.The ratchet 43 engaged with sprocket wheel 23 by driving cog and right side resilient mounting form torque limiter on the right side of sprocket wheel 23, the driving surface driving cog of torque limiter is made up of the boss 431 on ratchet 43 and the groove 231 on sprocket wheel 23, the contact surface of boss 431 and groove 231 is plane composition alternate with inclined-plane, during running will on inclined-plane transmission of pressure, and the inclined degree on inclined-plane determines the size of angle of obliquity.Sprocket wheel 23 and ratchet 43 are compressed by clutch spring 44, adjust clutch spring 44 deformation size by adjustment right side nut 47 and can control ratchet 43 and sprocket wheel 23 engagement force size, when moment of torsion is greater than power-transfer clutch setting value, the axial force that inclined-plane produces will be pushed ratchet 43 and clutch spring 44 open, and sprocket wheel 23 is separated with ratchet 43.Fig. 3 turns round power-transfer clutch bottom ratchet wheel 43 and sprocket wheel 23 engagement the normal time limit, and when Fig. 4 is abnormal, limit turns round power-transfer clutch work, sprocket wheel 23 and ratchet 43 released state.
During use, the base 1 of trailer coupling is arranged on the pallet inside of the load conveyor of conveyer, under normal working, sprocket wheel 23 is engaged in conveyor chain, opposing chain is static, advance under the drive of chain, when needs pallet stops time, stopper on conveyer can limit its motion, now because the friction force between the friction lining 31 of trailer coupling and friction pair part 32 is less than the barrier force of stopper, friction lining 31 and friction pair part 32 by relative sliding, thus make sprocket wheel 23 skid, and chain maintenance moves ahead and pallet stop motion.When the circular rail portion in the two ends moving to conveyer, track curvature increases, chain can withstand sprocket wheel 23, tween drive shaft 22 5 is rotated up around the shaft, apical axis 61 in now sprocket wheel swing arm 21 can withstand reset jacking block 62 and compress Compress Spring 63, ratchet 43 can be touched with the ratchet 42 on right side simultaneously, compress Compress Spring 63 simultaneously, ratchet device, by locked for ratchet 43, ensure that pallet mechanism's deadweight when two ends arc track up-and-down movement is greater than between friction lining 31 and friction pair part 32 and can not slide under friction situation.When pallet moves in horizontal rail, under Compress Spring effect, tween drive shaft 22 gets back to home position, and ratchet 43 and ratchet 42 are separated, and whole mechanism can normally work again.When being in unusual condition, when the pallet on the pallet overturn at arc-shaped rail and horizontal rail blocks, now because ratchet 43 and ratchet 42 are in engagement, sprocket wheel 23 is stuck can not normal rotation, now moment of torsion will be greater than torque limiting, sprocket wheel 23 is pushed ratchet 43 open with the axial force on ratchet 43 mesh inclined plane, ratchet 43 and sprocket wheel 23 are separated, avoid mechanism when sprocket wheel 23 and ratchet 43 still rotate and block the damage causing trailer coupling, chain and motor, thus play the effect that limit turns round power-transfer clutch.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
