The utility model discloses the operational mode is unanimous with traditional long-pending formula horizontal transport equipment of putting, changes to some extent on the drive mode of dolly. Compare with the tradition, its principle lies in, the utility model discloses optimize the friction stick of tradition and the frictional structure of sprocket, increased release mechanism. The release mechanism is composed of a stress rod 120, a stress rod 130, a push rod 140, a transmission connecting piece 150, a transmission rod 160 and a swing rod 170. The trolley with the structure takes the thrust of the latter trolley as the power for the disconnection of the damping mechanism of the current trolley. We refer to the previous cart as cart a and the subsequent cart as cart b.
When the stopper blocks the trolley a, the chain traction force is larger than the resistance force of the damper, so that the damper starts to rotate, the trolley a stops, and the chain wheel rotates in place. At the moment, the load of the damping module of the trolley a acts on the motor through the chain, when the next trolley b enters the buffer station, the connecting rod of the trolley a is pushed to separate the damping module of the trolley a from the chain wheel, and at the moment, the chain wheel of the trolley a rotates in situ, namely the trolley a does not occupy the power of the motor. By analogy, only 1 trolley occupies the motor power in the cache region, so that the cache quantity is greatly increased, the energy consumption is reduced, the replacement frequency of friction rods is reduced, and the environment protection is facilitated.
More specifically, the transport vehicle 100 travels at a constant speed along the chain 500 of the conveyor line. When the conveying trolley stopper 700 works and the conveying trolley 100 is blocked, the power of the chain is larger than the resistance of the permanent magnet damping module 181, the chain wheel 1000 rotates in place, and the conveying trolley 100 stops. At this time, when the next car approaches, the force-receiving rod 120 is pushed by the thrust rod 130, the force-receiving rod has elasticity, the force-receiving end of the force-receiving rod is connected with the force-receiving spring 121, the force-receiving spring 121 pushes the push rod 140, the push rod 140 resets the swing rod 170 through the transmission rod 160, the transmission rod 160 and the push rod 140 are connected with the transmission connecting piece 150, and the transmission connecting piece 150 is fixed on the car. The connection sleeve 171 at one end of the swing link 170 is used as a rotation fulcrum through the swing link fixing member 177, and the other end is connected with the sleeve 183 through the fixing clamp 174. The driving connecting shaft 173 is forced by the driving rod 160 to drive the fixed chuck 174 to move, the fixed chuck 174 pushes the sleeve 183 to retract,
as a result, the socket gear 184 connected to the socket 183 and the sprocket gear 185 on the sprocket 1000 are disengaged, and the swing spring 176 is stretched. At this time, the connection between the chain wheel 1000 and the permanent magnet damping module 181 is interrupted, and the chain wheel 1000 rotates in situ, that is, the trolley does not occupy the power of the motor, so that the energy consumption is reduced, and the replacement process caused by the loss of the friction rod is reduced. When the stopper is released, the swing spring 176 resets the swing rod 170, the sleeve gear 184 is meshed with the chain wheel gear 185, the permanent magnet damping module 181 transmits resistance to the chain wheel 1000 again, the torque provided by the permanent magnet damping module 181 is larger than the power required by the trolley to advance, and the trolley continues to advance.
The utility model discloses except having increased release mechanism, also improved power unit. The novel friction rod is embodied in a newly-added permanent magnet damping module 181, and replaces the traditional friction structure of the friction rod and the chain wheel. The conveying equipment with the structure takes the rotation of the chain wheel which is engaged with the chain as the power for advancing the trolley. When the stopper blocks the trolley, the braking force provided by the permanent magnet damping module 181 is not enough to resist the torque applied to the chain wheel 1000 by the chain, so that the chain wheel 1000 rotates in situ, thereby realizing the buffer function of the conveying equipment without stopping the line. Specifically, the permanent magnet damping module 181 is connected to the sprocket gear 185 through the sleeve gear 184, and the permanent magnet damping module 181 provides a resistance to the sprocket 1000 to keep the sprocket 1000 from rotating. Because the permanent magnetism damping module 181 principle is through electromagnetic induction with mechanical energy conversion to heat energy, consequently do not have the condition such as wearing and tearing, piece, avoid the loaded down with trivial details work that frequent change friction stick brought, and more do benefit to environmental protection.
The utility model discloses improve the whole of transport trolley 100, also embodied inventive feature in the detail simultaneously. Firstly, the square shaft 182 is used as a connecting shaft with the sleeve 183, and the joint of the sleeve 183 is also designed to be a square hole, so that the purpose is to require the simultaneous rotation of the sleeve 183 and avoid the problem of single rotation. On the other hand, the angle between the transmission rod 160 and the mounting surface 1100 of the transport carriage 100 in the preparation position is 60 ° to 70 °. In this embodiment 65. This angle is of great significance for the implementation of the present invention. If the angle is too small, the requirement on the pushing force is high, self locking cannot be formed, the stroke is insufficient, the gear on one side cannot be disengaged, and the power cannot be cut off. If the angle is too large, the jacking stroke is very small, so that self-locking cannot be realized.
Whether can realize to 65 contained angles the utility model discloses a flow, we have carried out the checking calculation through the formula. The power required by the trolley is 42N, and the effective moment of the damper is 42N and the radius of the chain wheel is 42mm and is 1.7 NM. The friction force F5 between the sleeve 183 and the square shaft 182 is (1.7NM/9.2mm) × 0.1 is 18.5N. Wherein the steel material has a non-lubricated dynamic friction coefficient of 0.1.
Return spring force F3 ≈ (dead weight of the sleeve, link, connector and the whole connected therewith). friction coefficient
0.6kg 0.1 (friction coefficient) gravity constant 9.8N 0.6N
The self friction force of the mechanism is mainly to overcome the friction between the transmission connecting piece 150 and the trolley frame caused by the pressure generated by the reaction force to the transmission connecting piece 150 when the square shaft sleeve is rubbed
F2 ═ ((F4+ F3) × 150/100 (arm ratio)) × 0.1 (coefficient of friction)
F2 ═ ((18.5N +0.6N) × 150/100 (arm ratio)) × 0.1 (coefficient of friction)
F2＝2.9N
Force F1 needed at moment of trolley disengagement-self friction force F2 of mechanism-elastic force F3 of return spring as X value
The value of X can be calculated according to the parallelogram rule, where X (18.5N 150/100) cot65 ° -13N
Thus, F1 ═ X + F2+ F3 ═ 13N +2.9N +0.6N ═ 16.5N
The thrust generated by the self weight of the trolley is 42N, 42N is more than 16.5N
Thus, the present invention is fully implementable.
The above description has been made of the embodiments of the present invention, but the present invention is not limited thereto, and various changes may be made without departing from the spirit of the present invention.
