Description
Technical Field
The utility model belongs to the technical field of the machine-building, concretely relates to nuclear fuel assembly highway transportation bracket.
Background
At present, with the increase of the number of certain type of nuclear power generating units in China, the demand of nuclear fuel assemblies used by the nuclear power generating units is increased day by day. The prokaryotic fuel assembly road transportation technology is that a bottom plate and a limiting device are additionally arranged on the basis of a common truck (the load capacity is 10t), only two groups of nuclear fuel assemblies can be transported by each truck, and the transportation efficiency is low; the additionally arranged device and the vehicle body are fixed and cannot be separated, the use purpose of the vehicle is restricted, and the original transportation technology cannot meet the development requirement.
Therefore, in view of the above-mentioned problems in the prior art, there is a need for an improved special rack for nuclear fuel assembly road transportation, which is suitable for loading on a container vehicle, flexible, convenient, safe and reliable
Disclosure of Invention
The utility model aims at the not enough of above-mentioned prior art, provide a nuclear fuel assembly highway transportation bracket for it is little to solve the haulage vehicle load capacity, installs the technical problem that device and automobile body are fixed additional.
The technical scheme of the utility model:
a nuclear fuel assembly road transportation bracket comprises an angle piece 1, a side beam A2, a side beam B4, a plurality of longitudinal beams 6, a plurality of bottom cross beams 3, a limiting strip 7, a positioning block 9 and a bolt hook 8, wherein the longitudinal beams 6 and the bottom cross beams 3 are fixedly arranged in a crisscross manner to form a fuel assembly supporting platform, the limiting strip 7 is arranged at the tail of the fuel assembly supporting platform, the positioning block 9 is arranged at the front of the fuel assembly supporting platform, and the side beam A2 and the side beam B4 are respectively arranged on two sides of the fuel assembly supporting platform; two ends of the limiting strip 7 are respectively fixed on the side beam A2 and the side beam B4; the two ends of the limiting strip 7 are respectively provided with a bolt hook 8 at the connection part of the side beam A2 and the side beam B4, and the four corners of the fuel assembly supporting platform are respectively provided with an angle piece 1.
Three equidistant lattices are arranged on the limiting strip 7 and used for placing a plurality of fuel assemblies.
And the side beam A2 and the side beam B4 are both provided with two hanging rings.
The corner fittings 1 are matched with a lock head of a container frame.
The utility model has the advantages that:
the utility model discloses a nuclear fuel assembly highway transportation bracket, simple structure, manufacturing, maintenance cost are low, and the installation is convenient with the dismantlement. The container car can be matched with all container cars with standard sizes of 20 feet, the function of transporting single, two or four nuclear fuel packs can be realized, and the effects of flexibility, convenience, safety and reliability are achieved.

Detailed Description
The invention will be further described with reference to the following figures and examples:
a nuclear fuel assembly road transportation bracket comprises an angle piece 1, a side beam A2, a side beam B4, a plurality of longitudinal beams 6, a plurality of bottom cross beams 3, a limiting strip 7, a positioning block 9, a bolt hook 8 and a floor patch board 5, wherein the longitudinal beams 6 and the bottom cross beams 3 are fixedly arranged in a crisscross manner to form a fuel assembly supporting platform, the limiting strip 7 is arranged at the tail of the fuel assembly supporting platform, the positioning block 9 is arranged at the front of the fuel assembly supporting platform, and the side beam A2 and the side beam B4 are respectively arranged at two sides of the fuel assembly supporting platform;
two ends of the limiting strip 7 are respectively fixed on the side beam A2 and the side beam B4; the two ends of the limiting strip 7 are respectively provided with a bolt hook 8 at the connection part of the side beam A2 and the side beam B4, and the bolt hooks are used for connecting and fixing a device of a nuclear fuel cargo bag;
and corner fittings 1 are arranged at four corners of the fuel assembly supporting platform and can be matched with a frame of a 20-foot container automobile.
Three equidistant lattices are arranged on the limiting strip 7 and used for placing a plurality of fuel assemblies.
Two hanging rings are arranged on the side beam A2 and the side beam B4 and used for hoisting and installing the whole bracket, and the floor patch panel 5 is connected with the side beam A2.
The corner fittings 1 are matched with a lock head of a container frame.
When the container is used, a crane is adopted to hoist the container to a 20-foot container frame through four lifting rings on the side beams 2 and 4 at two sides, and the four corner pieces 1 are matched and locked with a lock head of the container frame. Nuclear fuel goods package can be placed to 7 middles on spacing, and spacing 7 has three check, can place single goods package, two goods packages, four goods packages, can two-layer stack when placing four goods packages. After the nuclear fuel ladles are placed, the fixing devices are connected and tightened with the bolt hooks 8 on the side beams 2 and 4. It is ensured that the nuclear fuel package is not displaced during transport. After the transportation task is finished, the lock head of the container is loosened, and the bracket is lifted away from the frame.
