Description
Technical Field
The invention belongs to the field of fuel transportation equipment in nuclear industry, and particularly relates to a tipping mechanism with a tension compensation function.
Background
The main function of the fuel transportation equipment is to transport fuel assemblies between an auxiliary plant and a reactor plant of the nuclear power unit, and the fuel transportation equipment comprises the steps of transporting new fuel assemblies to the reactor plant from the auxiliary plant, and transporting spent fuel assemblies to the auxiliary plant from the reactor plant. The tipping mechanism is one of the key mechanisms of the fuel transportation equipment, and plays an important role in the operational reliability and the operational efficiency of the equipment. When the fuel transportation equipment loads and unloads fuel, the fuel basket of the tipping mechanism of the fuel transportation equipment needs to tip from a horizontal state to a vertical state or tip from the vertical state to the horizontal state.
The tipping mechanism of the present fuel transport equipment is composed of a winch, a transport trolley, a fuel basket, a steel wire rope, a heavy hammer group, a proximity switch and the like. The tipping mechanism drives the steel wire rope through the winch to drive the fuel basket to rotate around the rotating shaft by 0-90 degrees, the steel wire rope is wound in a pulley block of the transport trolley through a certain winding path, one end of the steel wire rope is fixedly connected with a winding drum of the winch, and the other end of the steel wire rope is connected with the heavy hammer group. The heavy hammer group is generally composed of a large heavy hammer and a small heavy hammer, the small heavy hammer is movably arranged in a cavity of the large heavy hammer, and the large heavy hammer and the small heavy hammer are respectively connected with a vertical proximity switch and a horizontal proximity switch of the fuel transportation equipment. The structure of the above-mentioned tilting mechanism can be referred to patent CN102097140B, in which the schematic diagram of the tilting mechanism and the force-bearing schematic diagram of the fuel basket are shown in fig. 1-2, respectively.
When the fuel basket is in a horizontal state (0 degree), the large heavy hammer is in contact with the ground, the small heavy hammer is suspended, the pre-tightening force of the steel wire rope 6 is provided by the small heavy hammer, namely the pulling force of the steel wire rope 6 is equal to the gravity of the small heavy hammer, and the vertical proximity switch and the horizontal proximity switch are both disconnected; when the winch 1 drives the fuel basket 4 to tip from the horizontal state to the vertical state through the steel wire rope 6, the tension of the steel wire rope 6 is greater than the gravity of the small heavy hammer and smaller than the gravity of the heavy hammer group, at the moment, the small heavy hammer is lifted, the horizontal approach switch is unblocked, the large heavy hammer is still contacted with the ground, and the vertical approach switch is disconnected; when the fuel basket 4 is tilted to a vertical state (90 degrees), the rotation is stopped due to the blocking of the limiting block, the winch 1 continues to move through the steel wire rope 6 and drives the heavy hammer to move upwards until the vertical proximity switch is unblocked, the winch 1 stops working, and at the moment, the horizontal proximity switch and the vertical proximity switch are unblocked.
When the fuel basket 4 of the fuel transportation equipment is tipped from 0 degree to 90 degrees, the force arm of the steel wire rope 6 for pulling the fuel basket 4 is gradually increased, the pulling force is gradually reduced until the pulling force of the steel wire rope 6 is minimum when the fuel basket 4 is in a vertical state of 90 degrees, and in order to ensure that a horizontal proximity switch is kept smooth in the tipping process, the gravity of a small heavy hammer is not greater than the pulling force of the steel wire rope when the fuel basket 4 is in the vertical state, namely the maximum weight of the small heavy hammer is limited. Therefore, when the fuel basket 4 is in a horizontal state, the tension of the steel wire rope 6 is provided by the small weight, so that when the distance between two supporting points of the steel wire rope 6 is long, the gravity of the steel wire rope 6 influences, and the gravity of the small weight is not enough to tension the steel wire rope 6, so that the deflection of the steel wire rope 6 is large, and the operation stability and the operation efficiency of the tipping mechanism are low.
The tipping mechanism is one of key mechanisms of the fuel transportation equipment, and plays an important role in the operational reliability and the operational efficiency of the equipment, because the deflection of a steel wire rope is large when the existing equipment is in a horizontal state of a fuel basket, the equipment is easy to be interfered by the outside when in horizontal operation and tipping operation, and the signal failure of a proximity switch is caused to generate parking, and meanwhile, the equipment needs to tension the steel wire rope in a low-speed state when in tipping operation so as to reduce the vertical swing of the fuel basket in the tipping process, and the steel wire rope needs to occupy a certain time when in tensioning, so that the operation efficiency of the equipment can be greatly improved by improving the tension of the steel wire rope, and the equipment has extremely.

Referring to fig. 7-9, the compensation mechanism of the elastic element and the design of the elastic element will be described by taking the torsion spring as an example.
The compensation torsion of the torsion spring is calculated as follows: torque balance formula when fuel basket tips: g × H =2 × F × L, i.e., F = G × H/(2 × L);
wherein: g-fuel basket weight, expressed in gravity;
h is the distance from the center of gravity of the fuel basket to the center of the rotating shaft;
f-single wire rope tension (actually 2 wire ropes);
l is the distance between the steel wire rope and the center of the rotating shaft.
The values for G, H, F, L above are shown in the table below for various tip angles.
As can be seen from the above table, when the fuel basket is tilted from 0 to 90 degrees, the pull force of the wire rope is reduced from 450.3N to 90.2N, i.e. the gravity of the small weight is not greater than 90.2N, therefore, the weight of the small weight is not greater than 9.2 kg. When the fuel basket is in a horizontal state, the tension of the steel wire rope is provided by the gravity of a small heavy hammer, namely 90.2N, the maximum sagging amount of the steel wire rope is 150mm, and the steel wire rope is in a loose state.
When the torsion spring is designed, the torsion deformation angle of the torsion spring is 0 degrees when the fuel basket is in a horizontal state, the torsion force is 0 degrees, and when the fuel basket is in a vertical state, the torsion deformation angle of the torsion spring is 90 degrees, and 360.1N compensation force needs to be provided for the steel wire rope. Thus, after the torsion spring is added, when the fuel basket is tilted from 0 degrees to 90 degrees, the tensile force of the steel wire rope is basically kept at 450.3N, namely the weight of the small weight is not more than 45.9kg (450.3/9.8), the weight of the small weight is increased to 25kg in consideration of the installation space of the small weight, the tensile force provided by the small weight is 245N (25 multiplied by 9.8) when the fuel basket is in a horizontal state, the maximum sagging amount of the steel wire rope is about 3mm, and the steel wire rope is in a tight state.
The torsion spring is designed as follows: when the fuel basket is in a vertical state, the torsion force of the torsion spring is calculated as follows: 2 XFNX S =2 × Δ F × L, i.e., N = Δ F × L/S;
wherein, FN-torque at maximum torsional deformation angle (90 °) (actually 2 torsion springs);
s-length of the torque arm;
Δ F — the compensating tension of a single wire rope (actually 2 wire ropes);
l-distance between the steel wire rope and the center of the rotating shaft
Therefore, the torsion force of the torsion spring at the maximum torsion deformation angle (90 °) can be calculated. According to the torsion provided by the torsion spring under the maximum deformation angle (90 degrees), the material physical property and the external dimension of the spring, the parameters of the torsion spring, such as the effective turn number, the diameter of the spring wire, the pitch diameter of the spring, and the like, are calculated according to the calculation method of a spring manual.
The tipping process of the fuel basket of the present invention will be described in detail.
The process that the fuel basket 4 is tilted from a horizontal state (0 degrees) to a vertical state (90 degrees): the initial position of the fuel basket 4 is horizontal, at this time, the large weight 701 contacts the ground, the small weight 702 is suspended in the large weight 701, and the vertical proximity switch 9 and the horizontal proximity switch 10 are both in an off state under the downward pulling force of the weights. When the winch 1 drives the steel wire rope 6 and drives the fuel basket 4 to tip upwards from a horizontal state, the small weight 702 moves upwards under the tension of the steel wire rope 6, and when the small weight 702 is in contact with the inner wall surface of the top of the large weight 701, the horizontal approach switch 9 is unblocked. During the tipping process, the elastic element 8 is squeezed by the fuel basket 4 and the transport trolley 3, the torsion force is gradually increased, and the reduction of the tensile force of the steel wire rope 6 caused by the increase of the moment arm is compensated, so that the tensile force of the steel wire rope 6 can be basically kept unchanged, the relative positions of the large heavy hammer 701 and the small heavy hammer 702 are kept unchanged, namely the horizontal proximity switch 9 is kept smooth, and the vertical proximity switch 10 is still disconnected; when the fuel basket 4 is in the vertical state and stops tipping due to the blocking of the limiting block 302, at the moment, the winch 1 continues to rotate, the small weight 702 and the large weight 701 are driven by the steel wire rope 6 to simultaneously ascend to the smooth state of triggering the vertical proximity switch 10, so that the winch 1 stops rotating, and at the moment, the horizontal proximity switch 9 and the vertical proximity switch 10 are both in the smooth state.
The process that the fuel basket 4 is overturned from the vertical state to the horizontal state: the initial position of the fuel basket 4 is vertical, at this time, the big weight 701 and the small weight 702 are suspended at the same time, and the vertical proximity switch 9 and the horizontal proximity switch 10 are both in the open state. When the winch 1 drives the steel wire rope 6 and drives the fuel basket 4 to tip downwards from a vertical state, the large heavy hammer 701 and the small heavy hammer 702 move downwards simultaneously until the large heavy hammer 701 is in contact with the ground, at the moment, the horizontal proximity switch 9 is unblocked, the vertical proximity switch 10 is disconnected, and due to the torsion compensation effect of the elastic element 8, the small heavy hammer 702 still keeps in contact with the inner wall surface of the top of the large heavy hammer 701 under the tension effect of the steel wire rope 6, namely, the relative positions of the two are unchanged, and the states of the horizontal proximity switch 9 and the vertical proximity switch 10 are unchanged; when the fuel basket 4 reaches the horizontal state and stops, the winch 1 continues to rotate, the small heavy hammer 702 is driven to descend through the steel wire rope 6 until the horizontal proximity switch 10 is switched off, the winch 1 stops rotating, and at the moment, the horizontal proximity switch 9 and the vertical proximity switch 10 are switched off.
In the process, the elastic element 8 can provide torque force to compensate the tension of the steel wire rope 6, so that the weight of the small heavy hammer 702 can be increased to reduce the deflection of the steel wire rope 6, improve the external interference resistance of the steel wire rope 6 and further improve the operation stability of the tipping mechanism, and after the deflection of the steel wire rope 6 is reduced, the time for tensioning the steel wire rope 6 can be effectively reduced when the fuel basket 4 is in tipping operation, and the operation efficiency of the fuel transportation equipment is greatly improved.
The above embodiments are only intended to illustrate the technical solution of the present invention and not to limit the same, and it should be understood by those of ordinary skill in the art that the specific embodiments of the present invention can be modified or substituted with equivalents with reference to the above embodiments, and any modifications or equivalents without departing from the spirit and scope of the present invention are within the scope of the claims to be appended.
