Abstract
The utility model belongs to the technical field of radioactive waste detection, and discloses a rotary platform mainly comprising a big rotation gear wheel, a small rotation gear wheel, a bearing bench and an electric roller; a rotation control motor is fixedly connected with the small gear wheel engaged with the big gear wheel fixed on the rotary bearing bench; the bearing bench is driven by the motor rotation to rotate; a waste barrel is place on the bearing bench; key points are that two sides of the platform are provided with guardrails, the other two sides are provided with position clip blocks, and the waste barrel enters the rotary platform from the position clip block direction; when the nucleus waste barrel enters a test position, a push rod motor below the position clip block is started to push the front block and the rear block to erect, thereby tightly clamping the nuclear waste barrel. The rotary platform is safe in operation, and enables the waste barrel to keep an unchanged position in the rotation process.
Description
Technical field
The utility model belongs to radioactive waste detection technique field, is specifically related to a kind of rotation platform.
Background technology
In order to carry out the clearing of nuclear facilities material balance and to analyze, need radionuclide content in some industrial process tailings of quantitative measurment or the nuclear waste, way is with in its standard pail for used dressings of packing into usually, then puts into specialized equipment and carries out quantitative measurment.In measuring process in order to improve measurement accuracy, the general mode that adopts the bucket rotation is with the minimizing impact that takes measurement of an angle, weight is when 100 kilograms to the 800 kilograms bucket fast rotational that do not wait, inertia is larger, in order to guarantee safety, the simultaneously accurate positioning when guaranteeing that bucket is measured needs a kind ofly can make the fixing rotary platform device in pail for used dressings position.
Summary of the invention
(One) utility model purpose
The utility model provides a kind of handling safety, can make the pail for used dressings rotation platform that the position remains unchanged in rotary course.
(2) technical scheme
The utility model provides a kind of rotation platform, this platform mainly comprises greatly, little swing pinion, bearing platform and motorized roller, wherein rotation control motor is fixedly connected with pinion wheel, pinion wheel and the gear wheel interlock that is fixed on the Rotatable load-bearing platform, and then rotarily drive bearing platform rotation by motor, pail for used dressings places on the bearing platform, key is, guardrail is equipped with in both sides at platform, and the screens block is equipped with in both sides in addition, and pail for used dressings enters rotation platform from screens block direction, after the nuclear waste bucket enters the measuring position, the push-rod electric machine that is positioned at screens block bottom starts, and block erects before and after promoting, and the nuclear waste bucket is closely blocked.
Preferably, push-rod electric machine resets after the pail for used dressings radioactivity survey finishes, and drives the fore-and-aft jam block and falls.
Preferably, the material of screens block is polyoxymethylene.
(3) beneficial effect
The rotation platform that adopts the utility model to provide, this platform adopt the design of guardrail and screens block can make that pail for used dressings can the holding position in the process that bearing platform rotates be fixed, handling safety, guarantee the accuracy of measuring.In addition, the material of screens block be light density material polyoxymethylene both can reduce γ and measured the time to the stopping of ray, also prevent from the bucket wall is produced damage.

Embodiment
Below in conjunction with specification drawings and specific embodiments the utility model is further elaborated.
The utility model provides a kind of rotation platform, this platform mainly comprises greatly, little swing pinion, bearing platform and motorized roller, wherein rotation control motor is fixedly connected with pinion wheel, pinion wheel and the gear wheel interlock that is fixed on the Rotatable load-bearing platform, and then rotarily drive bearing platform rotation by motor, pail for used dressings places on the bearing platform, key is, guardrail (1) is housed in the both sides of platform, screens block (2) is equipped with in both sides in addition, pail for used dressings enters rotation platform from screens block (2) direction, after the nuclear waste bucket entered the measuring position, the push-rod electric machine that is positioned at screens block (2) bottom started, and block erects before and after promoting, the nuclear waste bucket is closely blocked, such as Fig. 1.Push-rod electric machine resets after the pail for used dressings radioactivity survey finishes, and drives fore-and-aft jam block (2) and falls, and unclamps pail for used dressings, such as Fig. 2.The material of screens block (2) is polyoxymethylene.
Utilize this rotation platform as follows to the radiometric concrete operation step of pail for used dressings:
1, pail for used dressings enters on the bearing platform of rotation platform from screens block (2) direction, and electronic roll shaft setting in motion is transported to stop motion behind the measuring position with the nuclear waste bucket.
2, the front and back push-rod electric machine moves respectively, so that fore-and-aft jam block (2) erects, closely blocks pail for used dressings.
3, bearing platform drive nuclear waste bucket begins rotation.
4, after measurement finished, bearing platform stopped the rotation, and push-rod electric machine resets, and block falls before and after driving.
5, the platform roll shaft starts, and the nuclear waste bucket is transported to outside the rotary platform device.
Utilize this device that pail for used dressings is measured, handling safety, pail for used dressings position can keep immobilizing.
Claims (3)
1. rotation platform, this platform mainly comprises greatly, little swing pinion, bearing platform and motorized roller, wherein rotation control motor is fixedly connected with pinion wheel, pinion wheel and the gear wheel interlock that is fixed on the Rotatable load-bearing platform, and then rotarily drive bearing platform rotation by motor, pail for used dressings places on the bearing platform, it is characterized in that, guardrail (1) is housed in the both sides of platform, and screens block (2) is equipped with in both sides in addition, and pail for used dressings enters rotation platform from screens block (2) direction, after the nuclear waste bucket enters the measuring position, the push-rod electric machine that is positioned at screens block (2) bottom starts, and block erects before and after promoting, and the nuclear waste bucket is closely blocked.
2. rotation platform according to claim 1 is characterized in that, described push-rod electric machine resets after the pail for used dressings radioactivity survey finishes, and drives fore-and-aft jam block (2) and falls.
