Description

Technical Field

[0001] The invention belongs to the field of machinery, and in particular relates to a turning rack for unloading fuel rods. Background Art

[0002] During the transfer of fuel rods on the transmission line, some stations require manual entry of the rod number at one end of the fuel rod. Since the fuel rod is far away from the end of the transmission line after entering a certain process equipment, the operator needs to get under the transmission line and stand up to enter the data. In addition to the risk of operators contacting the fuel rods and affecting the cleanliness of the fuel rod surface, there is also a quality hazard of the fuel rods being collided and bent, and even dangerous situations such as head bumps or scratches may occur. In order to facilitate the continuous transfer of fuel rods, the original design did not consider the personnel channel separately, so it was considered to design the transmission line into two sections at some stations, and design a special flip rack to connect the two sections into one. Summary of the invention

[0003] The purpose of the present invention is to provide a tipping rack for unloading fuel rods, which can solve the problem of personnel freely entering and exiting and inputting fuel rod number data; solve the problem of not being able to realize the simultaneous use of personnel passage and fuel rod transmission; and eliminate the problem of personnel drilling under the transmission line for irregular operation.

[0004] The technical scheme of the present invention is as follows: a tipping rack for unloading fuel rods comprises an unloading rod, wherein the unloading rod is connected to a first semicircular clamp, the unloading rod is connected to a second semicircular clamp, the first semicircular clamp is connected to a shaft, a sleeve is divided into an upper and a lower part, which is clamped on both ends of the unloading rod on the shaft, a support is fixed to the frame by a third hexagon socket bolt and a third hexagon socket nut, the shaft is passed through a through hole on the upper part of the support, the shaft is passed through two supports, two sleeves are clamped and fixed on both ends of the shaft respectively, two semicircular clamps are clamped and fixed on the shaft, a first hexagon socket bolt and a first hexagon socket nut are used in combination to connect the first semicircular clamp to the unloading rod, wherein the first hexagon socket nut is in a groove at the bottom of the unloading rod, and the second semicircular clamp is used to fix a support rod, together forming a tic-tac-toe structure.

[0005] The feed rod is connected to the first semicircular clamp via a threaded structure.

[0006] The feed rod is connected to the second semicircular clamp via a threaded structure.

[0007] The first semicircular clamp is connected to the shaft through tolerance fitting.

[0008] The upper connection of the shaft sleeve is a through hole, and the lower part is a threaded hole. The two parts are fixed tightly by hexagon socket screws. The support is used for the main body support of the flip material rack.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] The tipping rack for unloading fuel rods provided by the present invention is in the shape of a "tic-tac-toe-shaped rack" that can rotate around an axis.

[0018] like Figure 1-3 As shown, the tipping rack for unloading fuel rods comprises an unloading rod 1, a first semicircular clamp 2, a shaft sleeve 3, a hexagon socket screw 4, a support 5, a shaft 6, a first hexagon socket bolt 7, a first hexagon socket nut 8, a second semicircular clamp 9, a support rod 10, a second hexagon socket bolt 11, a second hexagon socket nut 12, a third hexagon socket bolt 13, and a third hexagon socket nut 14;

[0019] The feed rod 1 is in direct contact with the fuel rods and provides support for the fuel rods. Its surface is made of soft plastic made of permissible materials. The feed rod 1 is connected to the first semicircular clamp 2 through a threaded structure, and the feed rod 1 is connected to the second semicircular clamp 9 through a threaded structure. After the first semicircular clamp 2 and the feed rod 1 form an integral body, it is used to realize the rotation of the feed rod 1 around the shaft 6. The first semicircular clamp 2 is connected to the feed rod 1 through a threaded structure, and the first semicircular clamp 2 is connected to the shaft 6 through a tolerance fit. The sleeve 3 is divided into two parts, upper and lower, which are clamped on the shaft 6, at both ends of the feed rod 1, mainly used to stop the feed rod 1 from sliding out from both sides, playing a role similar to a retaining ring. The upper connection of the sleeve 3 is a through hole, and the lower part is a threaded hole. The two parts are fixed tightly by the hexagon socket screw 4, and the support 5 is used to support the main body of the flip material rack. The support 5 is fixed to the frame by the third hexagon socket bolt 13 and the third hexagon socket nut 14. The shaft 6 is inserted into the upper through hole of the support 5, and the connection is achieved by tolerance fit, wherein the shaft 6 can rotate freely around the support 5. The shaft 6 is used for the rotation action of the discharge rod 1 to open / close. The shaft 6 is passed through the two supports 5, and the two sleeves are clamped and fixed at both ends of the shaft respectively, and the two first semicircular clamps 2 are clamped and fixed on the shaft 6. The first hexagon socket bolt 7 and the first hexagon socket nut 8 are used in combination to connect the first semicircular clamp 2 to the discharge rod 1, wherein the first hexagon socket nut 8 is in the bottom groove of the discharge rod 1. The second semicircular clamp 9 is used to fix the support rod 10, and together they form a well-shaped structure. The second semicircular clamp 9 fixes the support rod 10 by a clamping force, wherein the support rod 10 cannot rotate or move, and the second semicircular clamp 9 is connected to the discharge rod 1 by a threaded structure.

[0020] During use, the support rod 10 is manually operated to realize the opening / closing of the flip material rack. The support rod 10 is inserted into the two second semicircular clamps 9 and fixed by the clamping force. The second hexagon socket bolt 11 and the third hexagon socket nut are used together to connect the second semicircular clamp 9 to the feed rod 1, wherein the second hexagon socket nut 12 is in the bottom groove of the feed rod 1. The third hexagon socket bolt 13 and the third hexagon socket nut 14 are used together to connect the support 5 to the frame. The third hexagon socket bolt 13 and the third hexagon socket nut 14 fix the support 5 through a threaded structure.

[0021] When the fuel rods are being transferred, the flip rack is in a closed state; when manual entry / exit is required, the flip rack can be manually lifted / lowered.

[0022] (1) Segmented design

[0023] The transmission line is designed to be divided into two parts, which are connected by a flip material rack in the middle. When connected, the fuel rods can automatically flow to the next process; when disconnected, it serves as a manual channel and can enter the designated workstation for operation.

[0024] (2) Split design

[0025] The flip rack is designed to be composed of multiple parts, each of which is connected and fixed by friction or bolt structure, and can be quickly disassembled and assembled and are independent of each other. The lower rod used to support the fuel rod is in contact with the fuel rod for a long time and is easily damaged, so it can be quickly replaced separately.

[0026] (3) Tic-tac-toe structure design

[0027] Taking into account the need to achieve transmission line connection and frequent rotation, the flip rack is designed in a tic-tac-toe shape to enhance its anti-deformation ability. At the same time, the handrail of the tic-tac-toe structure can be used as a handle for the operator to hold, thereby realizing the flipping of the rack.

[0028] During the use of the present invention, the fuel rods can be transferred downwards by simply lowering the flip material rack; and the flip material rack can be raised, and the operator can stand upright and enter the designated work station for operation.
