SUMMARY

[0004] The utility model discloses a container overloading detection device prevents F-TR lock hook connection calibration device, can conveniently and quickly realize the calibration of F-TR lock hooking prevention detection module, improves the safety when using the overloading detection device.

[0005] The technical scheme of the utility model is as follows:

[0006] The container overloading detection device prevents F-TR lock hook connection calibration device, including simulation container, the weight of simulation container is matched with the weight of the container to be measured, simulation container includes bottom plate and stand, the upper end of stand is equipped with angle piece to be used for with the lock of lifting appliance cooperation, the bottom plate is provided with a plurality of support through holes that pass through the bottom plate, the support column is worn in the support through hole, the length of support column is greater than the thickness of bottom plate, the top of support column places with counterweight weight, the weight of counterweight weight is matched with the weight of simulation container flat car, and counterweight weight has certain interval with bottom plate, when lifting simulation container to counterweight weight and bottom plate contact, the weight of counterweight weight is loaded on the bottom plate to simulate F-TR lock hooking.

[0007] On the basis of the above scheme, further improvement is as follows, the interval between counterweight weight and bottom plate is 0-120mm. Because when lifting the container, F-TR lock is generally connected with the container in this range, the interval is set in this interval, the actual hooking situation can be more truly simulated, and the error caused by the variable is minimized.

[0008] On the basis of the above scheme, further improved as follows, one end of each support column is connected by a connecting plate into an integral structure. Connecting each support column into an integral structure through the connecting plate can make the disassembly and assembly of the support column more convenient and efficient, provide work efficiency, and if the connecting plate is arranged at the top of the support column, the counterweight weight can also be directly supported, the support area is increased, and the probability of side turning of the counterweight weight is reduced.

[0009] On the basis of the above scheme, further improved as follows, the bottom plate is provided with grooves for placing the weights, and the support holes are uniformly distributed in the grooves at the center of the bottom plate. Such arrangement can make the center of gravity of the counterweight weight coincide with the center of gravity of the bottom plate as much as possible, prevent side turning, and make the drilling length shorter when the support holes are machined, reduce the machining difficulty, and since the distance between the bottom plate and the counterweight weight is calculated from the groove bottom at this time, the length of the support column can be shortened under the same set distance.

[0011] On the basis of the above scheme, further improved as follows, the counterweight weight has a plurality of upper and lower stacked together. Since the counterweight weight needs to simulate the weight of the container flat car, and the weight of the container flat car is generally above 3 tons, and the weight of the weight is limited by machining and cannot be too large, the above contradiction can be solved by stacking multiple pieces.

[0012] On the basis of the above scheme, further improved as follows, the support holes and the corresponding support columns are four respectively, and are distributed in a square shape.

[0013] The beneficial effects of the present application are as follows: the present application matches the weight and size of the real container to be measured by simulating the container, to simulate the real situation as much as possible, sets the counterweight weight to simulate the weight of the container flat car, supports the counterweight weight by the support column at a certain distance, to simulate the situation that the F-TR lock can be hooked only after the container is lifted to a certain distance, and the real situation when the container is hooked by the F-TR lock is realized through the above simple scheme, so that the calibration variable is less and closer to the real scene, thereby improving the accuracy of calibration, and the above scheme is simple and convenient, so that the operation process is very simple and efficient, and the calibration of the anti-hooking detection module can be quickly realized.

[0022] The features and performance of the utility model will be further described in detail below in combination with examples.

[0023] An embodiment of the container overload detection device anti-F-TR lock hook connection calibration device of the utility model:

[0024] As Figure 2 , 4As shown, the container overloading detection device anti-F-TR hook connection calibration device comprises an analog container, the weight of the analog container matches the weight of the container to be detected, the analog container comprises a bottom plate 1 (i.e. a rectangular bottom plate 1) and a stand column 2, the upper end of the stand column 2 is provided with an angle piece 21 for cooperating with the rotating lock of the lifting tool, a plurality of support through holes 12 are arranged on the bottom plate 1, a support column 4 is arranged in the support through hole 12, the length of the support column 4 is greater than the thickness of the bottom plate 1, a counterweight weight is placed on the top of the support column 4, the weight of the counterweight weight matches the weight of the simulated container flat car, and there is a certain gap between the counterweight weight and the bottom plate 1, when the simulated container is lifted to the counterweight weight and the bottom plate 1 is in contact, the weight of the counterweight weight is loaded on the bottom plate 1 to simulate the F-TR hook connection. The gap between the counterweight weight and the bottom plate 1 is 0-120mm. Because when lifting the container, the F-TR lock is generally connected with the container within this range, the gap is set in this interval, which can more truly simulate the actual hooking condition and reduce the error caused by variables. One end of each support column 4 is connected into an integral structure through a connecting plate. Connecting the support columns 4 into an integral structure through the connecting plate can make the disassembly and assembly of the support columns 4 more convenient and fast, improve the work efficiency, and if the connecting plate is arranged at the top of the support column 4, the counterweight weight can be directly supported, the support area is increased, and the probability of the counterweight weight overturning is reduced. The bottom plate 1 is provided with a groove 11 for placing the weight, and the support through holes 12 are uniformly distributed in the groove 11 at the center of the bottom plate 1. Such an arrangement can make the center of gravity of the counterweight weight coincide with the center of gravity of the bottom plate 1 as much as possible, prevent overturning, and make the drilling length shorter when the support through holes 12 are machined, thereby reducing the machining difficulty, and because the gap between the bottom plate 1 and the counterweight weight is calculated from the groove bottom of the groove 11, the length of the support column 4 can be shortened under the same set gap. The counterweight weight has a plurality of upper and lower stacked together. Because the counterweight weight needs to simulate the weight of the container flat car, the weight of the container flat car is generally more than 3 tons, and the weight of the weight is limited by machining and cannot be too large, so the above contradiction can be solved by stacking multiple weights. The support through holes 12 and the corresponding support columns 4 are four respectively, and are distributed in a square shape.

[0025] The counterweight weight is placed on the support column 4 at the bottom of the simulated container to have a certain gap between the counterweight weight and the bottom plate 1, the weight of the simulated container matches the weight of the container to be detected; a plurality of support through holes 12 are arranged on the bottom of the simulated container, the support through holes 12 are arranged in the support column 4, and the length of the support column 4 is greater than the thickness of the bottom plate 1; the lifting tool of the container overloading detection device is connected with the simulated container, and the simulated container is lifted; when the bottom plate 1 of the simulated container is in contact with the counterweight weight, it is checked whether the anti-hooking detection module alarms.

[0026] The simulation container comprises a bottom plate 1 (a rectangular bottom plate 1), a stand column 2 and a plurality of counterweights arranged on the bottom plate 1, and the total weight of the bottom plate 1, the stand column 2 and the counterweights simulates the total weight of a real container. The distance between the counterweights and the bottom plate 1 is 0-120mm. One end of each support column 4 is connected by a connecting plate to form an integral structure. The bottom plate 1 is provided with recesses 11 for placing the counterweights, wherein the support perforations 12 are evenly distributed in the recess 11 at the center of the bottom plate 1. The center of gravity of the counterweights coincides with the center of gravity of the bottom plate 1. There are a plurality of counterweights stacked together.

[0027] The rectangular bottom plate 1 of the simulation container is provided with a plurality of positioning structure groups distributed along the length direction, each positioning structure group includes a plurality of positioning structures distributed along the width direction, a coordinate origin is arranged on the rectangular bottom plate 1, and the coordinate values of each positioning structure relative to the coordinate origin are known; each weight can be detachably connected with the positioning structure, and the positioning structure can fix the weight so that the center of gravity of the weight coincides with the center of the corresponding positioning structure; the positioning structure includes an empty load positioning structure without placing the weight and a loaded positioning structure with placing the weight, and the number and position of the empty load positioning structure are selected. The positioning structure is a groove 11 arranged on the rectangular bottom plate 1, and the shape and size of the groove 11 are the same as those of the bottom of the weight. Since the weight is relatively heavy, at least several hundred or thousands of kilograms, if other complex positioning structures are used, the operation adjustment precision requirement will be too high, and the groove 11 structure is used for positioning the weight, and the weight is directly placed thereon, on the one hand, the structure is simple and convenient to use, especially convenient for placing and taking out the weight, on the other hand, the weight of the weight is large, which is difficult to be taken out from the groove 11 by the self-weight limitation, and the effect of stable fixation is achieved. Five positioning structure groups are arranged along the length direction of the rectangular bottom plate 1, and each positioning structure group includes three positioning structures distributed along the width direction. This layout can select a standard 1-ton weight on the one hand, and can conveniently adjust the total weight and conveniently set the bias on the other hand. Four columns 2 are arranged on the four corners of the simulation container, and end parts of the four columns 2 are provided with corner pieces 21 for adaptively connecting with the swivel locks of the lifting device. The simulation container and the weight are moved by using a truck-mounted hoist transport vehicle, and the weight is hoisted and transported by using the crane of the truck-mounted hoist transport vehicle. The truck-mounted hoist transport vehicle, also known as the truck-mounted crane, is a standard product, which can be directly selected to avoid high cost of customization, and the crane of the truck-mounted crane can very conveniently hoist and transport the simulation container and the weight in the simulation container, such as adjusting the number of the weight, setting the bias, etc. When the total weight is calibrated without setting the bias, the loaded positioning structures are symmetrically arranged on the rectangular bottom plate 1. The total weight of the simulation container is changed by reducing the loaded positioning structures to meet the requirement of selecting the calibration points in the ranges of 5t-10t, 10t-15t and 15t-20t. The simulation container is made by removing the top plate and the side plate of a standard container. In this way, on the one hand, the cost of customization and processing is reduced, and on the other hand, the simulation container can more realistically simulate the container to be measured, thereby improving the calibration accuracy.

[0028] Specifically, as shown in Figure 1 the simulation container includes a rectangular bottom plate 1, a column 2 and a weight 3. In this embodiment, the simulation container is modified from a standard 20-foot container, and in other embodiments, it can be customized and processed.

[0029] Specifically, the rectangular base plate 1 is a rectangular plate, and a plurality of positioning structure groups are distributed in the length direction of the rectangular plate, each positioning structure group including a plurality of positioning structures uniformly distributed in the width direction. In this embodiment, the positioning structure is a groove 11 provided on the upper surface of the rectangular plate, and the shape of the groove 11 is adapted to the shape of the bottom of the weight 3 for positioning the weight 3 after being placed. Due to the large weight of the weight 3, the groove 11 allows the weight 3 to have only one degree of freedom in the upward direction, and due to its large weight, the weight 3 is not easily moved upward. The groove 11 not only facilitates the disassembly and assembly of the positioning structure, but also ensures that the weight 3 cannot be easily moved. The groove 11 is a rectangular slot, and the bottom of the weight 3 is a rectangular platform. There are five positioning structure groups, and each positioning structure group includes three positioning structures. Since the standard calibration method requires the total weight to be selected within the ranges of 5-10 tons, 10-15 tons, and 15-20 tons, a 3x5 matrix arrangement is provided by the positioning structures, and each weight 3 weighs 1 ton. By removing a certain number of weights 3, the total weight can be within the three weight ranges and the arrangement of each weight 3 can be uniform to complete the measurement when not shooting.

[0030] The weights 3 are multiple and are respectively detachably connected with the corresponding positioning structures. In this embodiment, there are 17 weights 3, and the corresponding grooves 11 have a total of 15 3x5 grooves. One or more weights 3 can be selectively placed in each groove 11, and when multiple weights 3 are present, they need to be stacked. Four cylindrical support holes 12 are provided in the groove 11 in the middle, and the four support holes 12 are uniformly distributed in the groove 11. Four support columns 4 are correspondingly provided, and the four support columns 4 can respectively slide in the support holes 12. The length of the support column 4 is greater than the thickness of the rectangular base plate 1, so that the weights 3 on the four support columns 4 can be lifted up, and the weights 3 have a certain distance from the groove bottom 11, which facilitates subsequent sudden loading of the rectangular base plate 1 to simulate the loading of the hook. The four support columns 4 can also be connected by a thin metal plate to form a whole, which is convenient for moving and using.

[0031] The four columns 2 are respectively fixed at the four corners of the rectangular base plate 1, and the top of the column 2 is provided with an angle piece 21 for adapting the turn lock of the spreader of the container overload detection device. The column 2 can also be increased, for example, several columns are symmetrically arranged on the long side of the rectangular base plate 1.

[0032] The calibration box or simulation container of the present application refers to a standard container after removing the side plates, removing the top plate, processing the grooves and support holes on the base plate, and adding counterweights to make the total weight the same as or similar to the total weight of the real container.

[0033] The coordinate origin in this embodiment is arranged at the center position of the base plate, and in other embodiments, it can also be arranged at one corner of the base plate.

[0034] The positioning structure of the embodiment is a groove, and in other embodiments, an electromagnet can be used as the positioning structure, the weight is attracted to the electromagnet, or a plurality of limiting columns are used to limit each weight.

[0035] The counterweight weights in the embodiment are ordinary weights, that is, the weights used for setting the deviation, and the function is to replace the weight of the container flat car. In the embodiment, three weights are provided, and the total weight is 3t, which is close to the weight of the container flat car.

[0036] In use, the truck crane can carry the simulation container to the position to be detected, the lifting arm can complete the lifting of the simulation container, the truck crane is convenient for docking with the container overload deviation detection device to be calibrated, the turn lock on the container spreader can be directly connected with the corner piece 21 at the four corners of the simulation container, the simulation container is convenient for lifting, a plurality of positioning structure groups are arranged on the rectangular bottom plate 1, each group includes a plurality of positioning structures, the coordinate positions of the positioning structures are fixed and measurable, the weight 3 is a standard weight, and the coordinate of the weight 3 is determined after the weight 3 is connected with the positioning structure, so that the subsequent calculation is facilitated, the weight 3 can be freely moved between the positioning structures, so that the deviation is set, and the subsequent calibration process is facilitated.

[0037] When the anti-hooking connection calibration of the F-TR lock is performed: a support column is installed in advance at the support perforation at the bottom of the groove in the middle of the bottom plate, a plurality of weights (as counterweight weights) are stacked on the top end of the support column by the crane of the truck crane, and the center of gravity of the counterweight weights is as close as possible to the center of the groove. The total weight of the simulation container and the weights inside the simulation container should be basically the same as or consistent with the total weight of the actual container to be detected. The turn lock of the spreader of the container overload deviation detection device is connected with the corner piece at the top of the simulation container stand, the simulation container is lifted, the anti-hooking detection module is continuously observed during the lifting process, whether the anti-hooking detection module alarms at the moment when the bottom plate of the simulation container contacts the counterweight weight is checked, if the alarm is normal, the anti-hooking detection module does not need to be adjusted, if the alarm is delayed, that is, the time from the contact between the bottom plate of the simulation container and the counterweight weight to the alarm is not within the predetermined range, the anti-hooking detection module is adjusted as much as possible to alarm in time, and if there is no alarm, the anti-hooking detection module is repaired or replaced. The simulation container is matched with the actual container to be detected in terms of weight and size in the application, so as to simulate the actual situation as much as possible. The counterweight weights are arranged to simulate the weight of the container flat car, the support column supports the counterweight weights at a certain distance, to simulate the situation that the F-TR lock can be hooked only after the container is lifted to a certain distance, so as to simulate the situation that the container is suddenly loaded when the container is hooked by the F-TR lock. The above simple scheme can realize the actual situation of the container and the container hooked by the F-TR lock, so that the calibration variables are fewer, the calibration is closer to the actual scene, and the calibration accuracy is improved. Moreover, the above scheme is simple and convenient, the operation process is very simple and efficient, and the calibration of the anti-hooking detection module can be quickly realized.

[0038] As can be seen, compared with the calibration methods in the prior art, this application has the advantages of convenient setting, calculation, adjustment and operation. Moreover, since the weight 3 is fixed by the positioning structure, it is not easy to move during the subsequent calibration process, thus having the characteristic of stable position, ensuring the accuracy of subsequent calibration.

[0039] The specific calibration process is as follows:

[0040] 1. Calibrate off-center loading, indication error, and repeatability

[0041] The load is applied with a standard weight that is at least 25% of the maximum weighing capacity of a single weighing sensor of the container overload / off-center load detection device. In this embodiment, a standard weight of 1 ton is used. Figure 3 As shown, first place 15 weights in the corresponding 15 grooves on the rectangular base plate, plus the weight of the simulated container itself (about 2 tons), for a total of 17 tons, which can directly meet the total weight range of 15-20t. By using the twist lock of the spreader of the container overload detection device to cooperate with the corner pieces on the four corners of the simulated container, the simulated container is lifted, so that the loaded weights can be applied to the weighing sensor as much as possible. Record the off-center load reading of the sensor, and its error should not exceed the maximum permissible error of the weighing range.

[0042] Subsequently, as Figure 3 The diagram shows that weights labeled 2, 7, 9, and 14 are lifted out using a crane, simulating a container weight of 13 tons. This satisfies the testing requirements for a total weight range of 10t-15t. Alternatively, weights 7, 8, and 9 can be lifted out, or weights 2, 5, 11, and 14 can be lifted out. That is, lifting out several weights that are in symmetrical positions, so that the remaining weights are still in symmetrical positions, can satisfy the testing requirements without bias. When bias is required, weights at a certain position can be lifted out, so that the overall position of the weights is no longer symmetrical.

[0043] Similarly, continue to lift a few more weights to bring the total weight to within the range of 5t-10t.

[0044] 2. Static Measurement

[0045] a) Place the weights inside the container in a rectangular array, with the remaining weights symmetrically positioned and their centers of gravity close to the center (i.e., both the preset values ​​for lateral offset and longitudinal offset are zero). Reliably reinforce the weights using the grooves on the rectangular base plate and their own weight. The detection device performs three prediction measurements (readings are optional) before the formal measurement. The suspended overload detection device should record the reading 5 seconds after the simulated container has been lifted and stabilized. The time between two measurements for the simulated container to reliably land should be no less than 5 minutes. Repeat the measurement 10 times. The error of the simulated container's total weight indication is calculated using formula (1).

[0046] (1)

[0047] wherein:

[0048] - indication error, %;

[0049] - average value of 10 measurements of the detection device, kg;

[0050] - nominal value of the weight of the weight, kg;

[0051] - reference value (20000), kg.

[0052] The transverse offset and the longitudinal offset static measurement indication error are respectively the difference between the corresponding parameter measurement result and the preset value. The static measurement repeatability is respectively the difference between the maximum value and the minimum value of 10 measurement data of the corresponding parameter.

[0053] b) Adjust the center of gravity position of the weights in the simulated container to set the offset, for example, hoist out the weights at a certain position, maintain the overall rectangular arrangement, the theoretical transverse offset is between 20 mm and 50 mm, the theoretical longitudinal offset weight is between 500 kg and 2000 kg (the weight of the weights in 50% of the length of the container shall not exceed 60% of the total weight of the weights), the preset value of the transverse offset of the simulated container is calculated according to formula (2), the preset value of the longitudinal offset weight is calculated according to formula (3), and the offset information is recorded. The total weight of the simulated container, the transverse offset, and the longitudinal offset weight are obtained according to the measurement process of step a), and the indication error and the repeatability are calculated.

[0054]

[0055] wherein:

[0056] - preset value of the transverse offset of the simulated container, mm;

[0057] - the mass of the i-th weight, kg;

[0058] - the horizontal coordinate of the center of gravity of the i-th weight, mm.

[0059]

[0060] wherein:

[0061] - preset value of the longitudinal offset weight of the container, kg;

[0062] - the longitudinal coordinate of the center of gravity of the i-th weight, mm;

[0063] Y-- Fixed distance, mm.

[0064] 3. Measurement of dynamic indication error

[0065] After completing steps a) and b), each calibration point is set before and after the calibration is performed.

[0066] The normal operating process was simulated by performing 10 consecutive measurements under different states of the simulated container (stable, swaying at different amplitudes, and lateral movement). The reliable landing time of the simulated container between two measurements was not less than 5 minutes. The dynamic measurement error of the total weight was calculated according to formula (1). The dynamic measurement errors of the lateral offset and longitudinal offset were respectively taken as the difference between the measurement results of the corresponding parameters of the detection device and the preset values. The dynamic measurement repeatability was respectively taken as the difference between the maximum and minimum values ​​of the 10 measurement data of the corresponding parameters.

[0067] 4. F-TR lock anti-snagging function test

[0068] like Figure 2 , 4 As shown, support columns of the same length are installed in the support perforations within the groove at the center of the rectangular base plate. The length of the support columns is greater than the thickness of the rectangular base plate. Multiple weights are stacked on top of the four support columns. When lifting the simulated container, the stacked weights are initially not in contact with the rectangular base plate, and the weight of the weights is not applied to the rectangular base plate. When the container is lifted to a certain distance, and the lower surface of the stacked weights contacts the bottom surface of the groove, the rectangular base plate will move upwards carrying the stacked weights. That is, the weight of the stacked weights will be instantly applied to the rectangular base plate, which can simulate the hooking of the F-TR lock onto the container. If the corresponding module of the container overload detection device alarms in time, the calibration result is normal; otherwise, the calibration result is abnormal, and the corresponding detection module needs to be repaired or replaced.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
