Abstract

The utility model relates to a piling-up and push-type direct-connected conveyer, which is used for chain type conveyor with a ring form drawing element. According to the existing piling-up and push-type direct-connected conveyer can not realize to solve the requirement of a stopping device and a non stopping device of two piling-up forms existing at the same time on one conveyer, thus, a rubber sealing member and an electro-magnet coil which are in the stopping device are easy to be damaged and failure which can not be avoided in the condition of strong irradiation and high temperature. The utility model designs that a mechanism which can pile-up just in an irradiation chamber can be realized by cancelling the stopping device to solve the technological problems. The mechanism which can alternate direction running by adopting a wagon group against an orbit at the same time, and a slewing mechanism is cancelled to enhance the reliability, the security and the economical efficiency of the transmission equipment undoubtedly. The utility model can be widely used in conditions, such as radicidation disinfecting, irradiation for food refreshment, material modification by irradiation, high temperature places, etc., which is an ideal equipment for processing by online transmitting.

Description

Piling-up and push-type direct-connected conveyer

The utility model relates to the chain-linked conveyer that is used to have the loop pulling element.

Stacking Type Hang Conveyer is a kind ofly to transport the equipment of article by set route, and it can be out of service in arbitrary appointed place, and follow-up car group can be accumulated successively.Can also enroll operation again by previously selected pause rhythm, whole process available computers control.Now, along with the development of nuclear technology, the means of conveyance that this is reliable has been widely used in various RADIATION PROCESSING.

Because RADIATION PROCESSING all is in and carries out automatically in the unsupervised environment, so, require to be in any controlled member in the high radiation field, must lasting anti-irradiation and do not lose efficacy, require to reduce moving parts, to guarantee the reliably absolute of transportation device as far as possible.But existing Stacking Type Hang Conveyer when requiring to be transferred article and stop in the appointed place, must be controlled by stopper and impulse sender.Yet rubber seal in the stopper or magnet coil are in high radiation field, and easy damaged lost efficacy, and caused Control Failure (seeing patent US3503337).Though adopting in radiation chamber of having lifted and to press rail amass to put, it can not satisfy road, labyrinth radiation chamber outside and loading and unloading material hall and still puts and the dispatch a car requirement of beat of any setting by stopper control is long-pending.

At not satisfying the working condition requirement that is used for special occasions on the Stacking Type Hang Conveyer function, the purpose of this utility model just is: at first, design that a kind of on same the chain-linked conveyer with loop pulling element two kinds of car tissues to be put the form collection be one, accomplish in radiation chamber, to cancel stopper and impulse sender long-pending the putting of can stopping, can satisfy road, labyrinth radiation chamber outside and loading and unloading material hall again and still control dispatch a car rhythm and parking freely and amass and put by stopper; Secondly, improvement leans on the swing type mechanism of machinery to realize the purpose that commutates in radiation chamber according to article.

The utility model is a kind of only free parking type of no stopper heap formula overhead chain conveyer in radiation chamber.Accompanying drawing 1,2,3,4 has illustrated its architectural feature.

The utility model is made up of traction track, bearing track, conduction chain push rod, car group and the car group commutation track etc. of arbitrary form, all there is the movable tailgate of swinging around fixed point ［ 4 ］ at the carrier bar two ends that it is characterized in that the car group, movable tailgate is hinged on the carrier bar ［ 3 ］ with pin, the side of fixing of movable tailgate is equipped with a roller ［ 10 ］, at its homonymy two ends metal sheets with a slope ［ 11 ］ and fixed steel bracket ［ 13 ］ is arranged.For Che Zuneng commutation operation, preceding dolly ［ 1 ］ and back dolly ［ 2 ］ are identical structure.The commutation operation of car group is finished by commutation track switch ［ 15 ］ and the arm-type device for shifting gears of slurry ［ 18 ］.Free parking type " power and free " chain conveyer with this conceptual design can achieve the above object.Now 1,2,3,4 describe its architectural feature again in detail in conjunction with the accompanying drawings.

1, car group and feature thereof

Illustrated by Fig. 1: the car group is made up of preceding dolly ［ 1 ］, back dolly ［ 2 ］, carrier bar ［ 3 ］ and two movable tailgates ［ 4 ］.The car group also claims free parking car.Be in dolly behind the title of dolly before the title in car group service direction the place ahead, back.The car group does not have fixing directivity.For Che Zuneng tune commutation operation, the front and back dolly must possess identical architectural feature.At the two ends of carrier bar ［ 3 ］ two movable tailgates of hinged installation ［ 4 ］, fall by the gravity vertical at ordinary times.

2, long-pending the putting of the movable tailgate of stopper arranged

The long-pending principle (see figure 1) of putting of the movable tailgate of stopper is arranged: stopper is the critical component of overhead chain conveyer, be provided with and need the place of stopping in the line, generally be that instruction by automatic computer comes its open and close of control electromagnetic valve, cylinder or high-speed double electromagnet, when stopper ［ 7 ］ when closing, its inclined-plane falls lifting pawl ［ 6 ］ on the preceding dolly ［ 1 ］ in the effect lower edge of stopper plate, forces the push rod ［ 8 ］ on the conduction chain to stop with lifting pawl ［ 6 ］ de-mesh.Meanwhile, by Fig. 1 and Fig. 2 as seen, the movable tailgate ［ 4 ］ on the back dolly, it is fixed a side roller ［ 10 ］ is housed, and by the two ends that are fixed on homonymy metal sheets with a slope ［ 11 ］, movable tailgate ［ 4 ］ is slowly promoted.Golden plate with a slope ［ 11 ］ is to determine its length according to the quantity of stopping on the laying section, and is fixed on a side of track by shape steel bracket ［ 13 ］.

Because the movable tailgate ［ 4 ］ on the back dolly of first car group is a wedge, can make the preceding shovel ［ 9 ］ on the preceding dolly of follow-up second car group of coming lift (see figure 1).Force the lifting pawl to descend by articulated linkage ［ 12 ］, push rod on the conduction chain and dolly jump out of mesh, and stop.So just, the car group of coming is in succession amassed one by one and put away.

When stopper leans on instruction unpack, the lifting pawl ［ 6 ］ of first car group is under the effect of preceding shovel ［ 5 ］ gravity and rise, wait for that follow-up conduction chain push rod marches forward its band, movable subsequently tailgate ［ 4 ］ breaks away from the preceding shovel ［ 9 ］ of second car, and the lifting pawl rises wait and enrolls operation.

Adopt the long-pending mode of putting of the movable tailgate of stopper, only be arranged on outer road, labyrinth of radiation chamber and loading and unloading hall, purpose is for control and adjusting flexibly the dispatch a car rhythm and the loading and unloading material that stops.

3, the long-pending (see figure 3) of putting of no stopper

The long-pending principle of putting of no stopper is seen shown in Figure 3.On the preceding shovel ［ 5 ］ of the preceding dolly of each car group, the quarter butt of a band roller ［ 19 ］ all is housed at homonymy, (cross sectional drawing is similar with Fig. 2 to be that the roller high and low position is different), when roller ［ 19 ］ is run into the long-bar metal plate ［ 14 ］ that is arranged on the track outside, roller lifts preceding shovel ［ 5 ］, force lifting pawl ［ 6 ］ to fall, and throw off and stop with conduction chain push rod ［ 8 ］.The follow-up second car group of coming is just passed a spacing with first car group again by carrier bar ［ 3 ］, can stop again by same principle.According to the long-pending car number of putting on the laying section, the length of design long-bar metal plate ［ 14 ］.The place ahead is ejected the car group of long-bar metal plate ［ 14 ］, and its roller ［ 19 ］ just leaves metal sheet, and preceding shovel ［ 5 ］ is by gravity fall, and lifting pawl ［ 6 ］ rises, and the special conduction chain push rod of this car group makes it to be sent to next laying section.Before lifting, the shovel, also can adopt and lift rail, press rail to realize the go-cart requirement by the metal long slab.

4, car group commutation track (Fig. 4)

When irradiation devices adopted the veneer source, needing will be by irradiated material at the middle position Rotate 180 of radiation field °, to satisfy the requirement of dose uniformity.A kind of is leaned on track itself, and needn't adopt machinery rotation formula mechanism, and the track of the operation that just can commutate is called car group commutation track.

Its reversing principle is seen shown in Figure 4.Push rod on the tow chain is brought the car group by track adjusting wheel into is pushed the commutation track switch ［ 15 ］ of trouble tongue ［ 16 ］ that automatically resets open by going into end, by fixing stopper ［ 17 ］ the car group is stopped.Change and to remove through starching arm-type device for shifting gears ［ 18 ］, the car group is passed to the opposite side of track switch ［ 15 ］ because preceding dolly and back dolly have same structure, the conduction chain push rod that returns again with the lifting pawl engagement of former back dolly, the car group is delivered to the side in addition in veneer source.At this moment the forward and backward dolly transposition of car group moves and finish the tune commutation.

Enforcement of the present utility model just on the basis of free parking type " power and free " chain conveyer series, with the function of carrier bar increase activity tailgate, and is set up the arm-type device for shifting gears of slurry and can be realized on the commutation turnout.

No stopper Stacking Type Hang Conveyer compared with prior art has the following advantages in the radiation chamber:

1, can be on same chain-linked conveyer, by the different requirements of working environment, select to have that stopper is long-pending puts and do not have that stopper is long-pending to be put.For the free parking type " power and free " chain conveyer has increased new function.

2, long-pending the putting of no stopper is arranged in some special occasions, as harsh environment occasions such as RADIATION PROCESSING and high temperature.Because it can cancel all control elements and operating element,, improved reliability of operation so got rid of the intrinsic hidden danger that the control element easy damaged lost efficacy.

3, utilize the car group can realize not having the function of tune commutation in orbit, cancelled mechanical 180 ° of swing type mechanisms.Both safe and reliable, simplified the structure of car group again.

In a word, the utility model is a new industry--RADIATION PROCESSING provides a kind of simple in structure, reliable, reduced investment, irradiation good evenness, the means of delivery of the nuclear radiation on-line machining that the degree of utilization in source is high.Special occasions such as its radiation modification that is developed as radiation sterilization sterilization, food irradiation fresh-keeping, material and high temperature provide plants desirable means of conveyance.
