Abstract
The utility model discloses an improved rotary drum device, which includes a rotary drum pin, a rotary drum, restraining ancones and a nut, as well as an anti-rotation block, wherein the restraining ancones are arranged at the two ends of the rotary drum symmetrically; the anti-rotation block is welded to the outer end of one restraining ancon; the end welded with the anti-rotation block, of the rotary drum pin, penetrates through the rotary drum and the restraining ancones; and the other end of the rotary drum pin is locked by the nut. As the anti-rotation block is welded on the one surface of the tail of the rotary drum pin, the pin cannot rotate in pin holes of the restraining ancones even through the rotary drum pin becomes loose, and abrasion of the pin and the holes can be avoided; and the improved rotary drum device provided by the utility model prolongs the service life of the rotary drum device, saves the maintenance cost, reduces the labor intensity of workers and improves the economic benefits.
Description
Technical field
The utility model relates to the roller device of railway automatic dumping car, belongs to the cylinder field.
Background technology
Find that inhibition knuckle-pin hole, roller pin, drum of damage in roller device are serious in the maintenance of overturning, change frequently, increased maintenance amount and the cost of overhaul.Roller device is being studied table tennis, discovery is that vehicle is in operation, because vibration makes roller pin loosening, vehicle rises when turning over, and roller pin will be rotated in suppressing the knuckle-pin hole, rather than cylinder rotates, so just aggravate roller pin and the wearing and tearing that suppress the knuckle-pin hole, caused roller device damage and lost efficacy.As untimely reparation, just might cause the generation of the accidents such as loose side.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of follow-on roller device, has avoided the wearing and tearing in pin and hole, plays the safety guard-safeguard effect.
A kind of follow-on roller device of the utility model, it comprises roller pin, cylinder, inhibition elbow and nut, it is characterized in that: further comprising Anti-rotary block, the two ends of cylinder are symmetrical arranged the inhibition elbow, Anti-rotary block is welded on one of them outer end that suppresses elbow, roller pin is passed cylinder and is suppressed elbow, other end nut locking from an end that is welded with Anti-rotary block.
Anti-rotary block described above is square, is complementary with the roller pin afterbody is square.
The utility model because in roller pin afterbody single-sided welding Anti-rotary block, even roller pin is loosening, pin can not rotate in suppressing the knuckle-pin hole yet, has avoided the wearing and tearing in pin and hole.Because the rolling of effect roller pin in folding of Anti-rotary block is lopsided wear, when roller pin may wear in limited time, roller pin Rotate 180 degree is reinstalled can continue to use once, a pin can use (as Fig. 1) twice.In addition, because Anti-rotary block is single-sided welding, in case cylinder and roller pin are stuck, the roller pin moment of rotation strengthens, and at this moment Anti-rotary block will come off, and the detaining car accident can not occur, and plays the safety guard-safeguard effect.
Description of drawings
Fig. 1 is the structural representation of this Novel rotary drum device;
Fig. 2 is the cutaway view along A-A line in Fig. 1;
Fig. 3 is the front view of Anti-rotary block in the utility model;
Fig. 4 is the left view of Fig. 3.
In figure: 1, roller pin 2, Anti-rotary block 3, cylinder 4, inhibition elbow 5, nut.
The specific embodiment
From Fig. 1, Fig. 2 as can be known, this novel a kind of follow-on roller device, it comprises roller pin 1, cylinder 3, suppresses elbow 4 and nut 5, it also comprises Anti-rotary block 2, the two ends of cylinder 3 are symmetrical arranged and suppress elbow 4, Anti-rotary block 2 is welded on one of them outer end that suppresses elbow 4, and roller pin 1 is passed cylinder 3 and suppressed elbow 4 from an end that is welded with Anti-rotary block 2, and the other end is locked with nut 5.
The utility model because in roller pin afterbody single-sided welding Anti-rotary block, even roller pin is loosening, pin can not rotate in suppressing the knuckle-pin hole yet, has avoided the wearing and tearing in pin and hole.Because the rolling of effect roller pin in folding of Anti-rotary block is lopsided wear, when roller pin may wear in limited time, roller pin Rotate 180 degree is reinstalled can continue to use once, a pin can use (as Fig. 1) twice.In addition, because Anti-rotary block is single-sided welding, in case cylinder and roller pin are stuck, the roller pin moment of rotation strengthens, and at this moment Anti-rotary block will come off, and the detaining car accident can not occur, and plays the safety guard-safeguard effect.And if there is no Anti-rotary block, vehicle is in operation and will soon becomes flexible because vibrating nut, the contact surface of cylinder and pin is greater than pin and the contact surface that suppresses the elbow hole, will cause pin to rotate in suppressing the elbow hole, and cylinder does not turn, roller device lost efficacy, and will soon cause roller pin and suppress elbow hole damage, and cylinder is stuck.
Adopt follow-on roller device described in the utility model, extended the service life of roller device, saved maintenance cost, reduced workman's labour intensity, increased economic benefit.
