Description

Technical Field

[0001] This application belongs to the technical field of maintenance equipment management, and particularly relates to a method for containerizing maintenance equipment. Background Art

[0002] The containerization of maintenance equipment is an important part of the management of maintenance equipment and materials. The unitization technology of maintenance equipment containers has been widely applied in the industry, and the proportion of container transportation in material transportation is increasing continuously.

[0003] Currently, the containerization process of material unitization still mainly relies on manual subjective experience for loading, resulting in a low overall level of containerization.

[0004] Therefore, there is an urgent need for a method for containerizing maintenance equipment that can improve the loading speed and space utilization rate. Summary of the Invention

[0005] To overcome the problems existing in the related art, a method for containerizing maintenance equipment provided by an embodiment of this application improves the containerization efficiency of maintenance equipment and the space utilization rate of maintenance equipment containers.

[0006] This application is implemented through the following technical solutions:

[0007] An embodiment of this application provides a method for containerizing maintenance equipment, including: obtaining maintenance equipment data, where the data includes the weight, size, and type of the maintenance equipment. Based on the maintenance equipment data, pre-containerization of the maintenance equipment is performed. The pre-containerization of the maintenance equipment includes sequentially marking the maintenance equipment as first-sequence maintenance equipment, second-sequence maintenance equipment, and third-sequence maintenance equipment based on the data. According to the order from the first-sequence maintenance equipment to the third-sequence maintenance equipment and various containerization methods, containerization of the maintenance equipment is performed.

[0008] In a possible implementation manner, the pre-containerization of the maintenance equipment includes marking the maintenance equipment as first-sequence maintenance equipment, including: comparing the weight of the maintenance equipment with the weight threshold of the maintenance equipment. If the weight is greater than or equal to the weight threshold of the maintenance equipment, the maintenance equipment is marked as first-sequence maintenance equipment. If the weight is less than the weight threshold of the maintenance equipment, the maintenance equipment is marked as candidate maintenance equipment. Comparing the size of the maintenance equipment with the size threshold of the maintenance equipment. If the size is greater than or equal to the size threshold of the maintenance equipment, the maintenance equipment is marked as first-sequence maintenance equipment. If the size is less than the size threshold of the maintenance equipment, the maintenance equipment is marked as candidate maintenance equipment.

[0009] In a possible implementation manner, the size threshold of the maintenance equipment includes: the shortest side size threshold, the second shortest side size threshold, and the longest side size threshold. If the size is less than any one of the shortest side size threshold, the second shortest side size threshold, and the longest side size threshold, the maintenance equipment is marked as candidate maintenance equipment.

[0010] In a possible implementation, the pre - containerization of maintenance equipment includes marking the maintenance equipment as the second - sequence maintenance equipment, which includes: comparing the influence coefficient of the candidate maintenance equipment with the influence - coefficient threshold. If the influence coefficient is greater than the influence - coefficient threshold, the maintenance equipment in the candidate maintenance equipment is marked as the second - sequence maintenance equipment; if the influence coefficient is less than the influence - coefficient threshold, the maintenance equipment in the candidate maintenance equipment is marked as the third - sequence maintenance equipment. Wherein, the influence coefficient represents the influence on the container space when any maintenance equipment is containerized.

[0011] In a possible implementation, the influence coefficient is determined based on the occupied space of the candidate maintenance equipment and the occupied space of all candidate maintenance equipment. The expression of the influence coefficient is:

[0012]

[0013] In the formula, δ i represents the influence coefficient of the i - th candidate maintenance equipment, N represents the number of all candidate maintenance equipment, V n represents the occupied space of the n - th candidate maintenance equipment, represents the occupied space of other candidate maintenance equipment except the i - th candidate maintenance equipment, and V represents the occupied space of all candidate maintenance equipment.

[0014] In a possible implementation, the pre - containerization of maintenance equipment includes marking the maintenance equipment as the third - sequence maintenance equipment, which includes: sorting each maintenance equipment in the third - sequence maintenance equipment based on the type of the maintenance equipment. The type includes the sub - assemblies and equipment to which the maintenance equipment belongs. The equipment includes multiple sub - assemblies, and each sub - assembly contains multiple maintenance equipment.

[0015] In a possible implementation, sorting the maintenance equipment in the third - sequence maintenance equipment based on the type of the maintenance equipment includes: grouping the maintenance equipment in the third - sequence maintenance equipment according to the sub - assemblies to which they belong, and classifying the maintenance equipment belonging to the same sub - assembly into one group. Grouping the maintenance equipment belonging to the same sub - assembly according to the equipment to which they belong, and classifying the maintenance equipment belonging to the same equipment into one group.

[0016] In a possible implementation, multiple containerization methods include: the containerization method along the Z - axis direction, the containerization method along the X - axis direction, and the mixed containerization method. Among them, the loading direction of the containerization method along the Z - axis direction is different from that of the containerization method along the X - axis direction, and the mixed containerization method is a mixed method that combines the containerization method along the Z - axis direction and the containerization method along the X - axis direction.

[0017] In a possible implementation, the containerization method along the Z-axis direction includes: after loading the maintenance equipment into the drawer of the maintenance equipment box, dividing the remaining drawer space into a first space, a second space, and a third space, where the first space is smaller than the second space, and the second space is smaller than the third space. Containerization is carried out in accordance with the principle of preferentially containerizing small spaces.

[0018] In a possible implementation, when containerizing maintenance equipment, the principle of maximum space utilization rate should also be considered. The principle of maximum space utilization rate includes: containerizing the first maintenance equipment with the largest bottom area as the bottom surface, the shortest side as the height, and the longest side perpendicular to the containerization direction of the maintenance equipment. Except for the first maintenance equipment, if the maintenance equipment can be containerized in multiple ways, the method with the smallest bottom area and the shortest side in the same direction as the maintenance equipment should be selected for containerization.

[0019] The beneficial effects of the embodiments of the present application compared with the prior art are:

[0020] The embodiments of the present application are applied to a drawer-type maintenance equipment box. First, data such as the weight, size, and type of the maintenance equipment are obtained, then the maintenance equipment is pre-containerized based on the relevant data, and finally, in accordance with the order of the first sequence of maintenance equipment to the third sequence of maintenance equipment marked during pre-containerization, and multiple containerization methods, the maintenance equipment is containerized. The present application provides a guiding method for containerizing maintenance equipment. Through the pre-containerization of the maintenance equipment, screening and marking are carried out on the maintenance equipment, which can enable the containerization personnel to have an awareness of data quantification for the maintenance equipment and the maintenance equipment container to be containerized, and avoid the problem of low space utilization rate of the maintenance equipment container due to loading based on subjective experience.

It should be understood that the specific embodiments described below are only used to explain this application and are not used to limit this application.

[0035] An embodiment of this application provides a method for assembling maintenance equipment, which is applied to a drawer-type maintenance equipment box. Figure 1 The schematic diagram of the drawer-type maintenance equipment box provided by an embodiment of this application is shown. For the sake of convenience of description, only parts related to the embodiments of the present invention are shown. The following will be described in conjunction with Figure 1 the maintenance equipment box.

[0036] In some embodiments, the maintenance equipment box includes a side plate 1, a bottom plate 2, a drawer 3, and a bottom plate 4. It should be noted that, in order to clearly show the internal structure of the maintenance equipment box, Figure 1 the front panel of the maintenance equipment box is omitted.

[0037] Referring to Figure 1 as shown, there can be multiple drawers in the maintenance equipment box, and the maintenance equipment is assembled into the drawers.

[0038] The following will be described in detail in conjunction with Figure 1 the method for assembling maintenance equipment provided by this application.

[0039] Figure 2 is the flowchart of the method for assembling maintenance equipment provided by an embodiment of this application. Referring to Figure 2 , this method may include steps 101 to 103, which are described in detail as follows:

[0040] In step 101, maintenance equipment data is obtained.

[0041] In some embodiments, the obtained maintenance equipment data may include the weight of the maintenance equipment, the size of the maintenance equipment, and the type of the maintenance equipment.

[0042] Optionally, the weight and size of the maintenance equipment are the weight and size after packaging.

[0043] In some embodiments, the dimensions of the maintenance equipment may include the shortest side dimension, the second shortest side dimension, and the longest side dimension of the maintenance equipment.

[0044] In some embodiments, the types of maintenance equipment may be classified according to the components and equipment to which they belong. Among them, each piece of equipment may include multiple components, and each component may include multiple maintenance equipment.

[0045] Optionally, the types of maintenance equipment may also be classified according to their functions and uses. This application does not further limit the types of maintenance equipment.

[0046] Step 101 quantifies the main indicators during the containerization of maintenance equipment, providing theoretical support for subsequent pre-containerization and avoiding blind containerization of maintenance equipment.

[0047] In step 102, pre-containerization of maintenance equipment is performed based on the maintenance equipment data.

[0048] When the quantity and types of maintenance equipment to be containerized are large, in order to avoid blind containerization or containerization based solely on subjective understanding, pre-containerization of maintenance equipment is required. Pre-containerization can also be understood as screening, marking, classifying, and sorting the maintenance equipment according to the obtained maintenance equipment data, providing a quantitative understanding of the occupied space and approximate containerization order of each piece of maintenance equipment for subsequent containerization of maintenance equipment.

[0049] In some embodiments, the pre-containerization of maintenance equipment may include sequentially marking the maintenance equipment as first-sequence maintenance equipment, second-sequence maintenance equipment, and third-sequence maintenance equipment based on the obtained maintenance equipment data.

[0050] Figure 3 is a schematic flow diagram of the pre-containerization of maintenance equipment provided by an embodiment of the present application. Refer to Figure 3 , the pre-containerization process may include steps 1021 to 1023, which will be described in detail below in combination with Figure 3 :

[0051] In step 1021, the first-sequence maintenance equipment is marked based on the weight and dimensions of the maintenance equipment.

[0052] In some embodiments, marking the first-sequence maintenance equipment may perform the following steps:

[0053] Exemplarily, compare the weight of the maintenance equipment with the weight threshold of the maintenance equipment. If the weight is greater than or equal to the weight threshold, mark the maintenance equipment as first-sequence maintenance equipment; if the weight is less than the weight threshold, mark the maintenance equipment as candidate maintenance equipment. Marking the candidate maintenance equipment is for further screening and sorting later.

[0054] Optionally, the weight threshold of the maintenance equipment can be adaptively set according to factors such as the load-bearing capacity of the maintenance equipment box, the load-bearing capacity of the drawers inside the box, and the number of maintenance equipment boxes. When the load-bearing capacity of the box or drawer is good, the weight threshold can be set larger; when the number of maintenance equipment boxes is sufficient, the weight threshold can be set smaller to reduce the weight of the box after containerization and facilitate subsequent handling and use.

[0055] Exemplarily, compare the size of the maintenance equipment with the size threshold of the maintenance equipment. If the size is greater than or equal to the size threshold, mark the maintenance equipment as the first-sequence maintenance equipment; if the size is less than the size threshold, mark the maintenance equipment as the maintenance equipment to be selected.

[0056] Similarly, the size threshold of the maintenance equipment can be adaptively set according to factors such as the size of the maintenance equipment box, and the quantity and size of all maintenance equipment. This application will not further limit the weight threshold and size threshold.

[0057] Optionally, in order to improve the space utilization rate of the maintenance equipment box during subsequent containerization, corresponding thresholds can be set respectively according to the size of the maintenance equipment. For example, the size threshold of the maintenance equipment can include the shortest side size threshold, the second shortest side size threshold, and the longest side size threshold.

[0058] Furthermore, when any one of the sizes of the maintenance equipment is greater than the corresponding size threshold, mark the maintenance equipment as the first maintenance equipment.

[0059] It should be noted that the screening of the maintenance equipment by the weight threshold or the size threshold is not in a specific order. That is, the screening can be carried out first by the weight threshold or first by the size threshold. However, as long as it exceeds any one of the weight threshold or the size threshold, it is marked as the first-sequence maintenance equipment.

[0060] Step 1021 preliminarily screens the maintenance equipment to be containerized based on weight and size. The purpose is to screen out the maintenance equipment with heavy weight and large volume and place it in the bottom drawer of the maintenance equipment box during containerization to ensure the stability of the box during transportation and retrieval. Therefore, mark the maintenance equipment with heavy weight and large volume as the first-sequence maintenance equipment, and mark the maintenance equipment with relatively light weight and relatively small volume as the maintenance equipment to be selected.

[0061] In step 1022, mark the second-sequence maintenance equipment based on the influence coefficient of the maintenance equipment.

[0062] As is well known, different maintenance equipment occupies different spaces. To make full use of the limited space in the drawer, the larger maintenance equipment can be pre-packed first, and the relatively smaller ones can be dispersed and packed later. Therefore, the concept of influence coefficient is introduced in this application, and the influence coefficient of candidate maintenance equipment is determined. The so-called influence coefficient can characterize the impact on the space during the packing of any maintenance equipment.

[0063] In some embodiments, the influence coefficient of candidate maintenance equipment is determined based on the space occupied by the candidate maintenance equipment and the space occupied by all candidate maintenance equipment. Exemplarily, the expression of the influence coefficient can be:

[0064]

[0065] In the formula, δ i represents the influence coefficient of the i-th candidate maintenance equipment, N represents the number of all candidate maintenance equipment, V n represents the space occupied by the n-th candidate maintenance equipment, represents the space occupied by other candidate maintenance equipment except the i-th candidate maintenance equipment, and V represents the space occupied by all candidate maintenance equipment.

[0066] It can be seen from the above formula that the influence coefficient of this application is not directly determined by calculating the ratio of the space occupied by a certain maintenance equipment to the space occupied by all maintenance equipment, but by removing the space occupied by a certain maintenance equipment to inversely calculate its impact on all candidate maintenance equipment. The purpose is to more accurately determine the impact of a certain maintenance equipment on the whole. For example, some particularly small maintenance equipment can be packed in the remaining narrow space after other maintenance equipment is packed.

[0067] In some embodiments, based on the influence coefficient, the candidate maintenance equipment can be marked as the second sequence maintenance equipment. The example method is as follows:

[0068] Compare the influence coefficient of the maintenance equipment with the influence coefficient threshold. If the influence coefficient is greater than the influence coefficient, mark this maintenance equipment in the candidate maintenance equipment as the second sequence maintenance equipment; if the influence coefficient is less than the influence coefficient threshold, mark this maintenance equipment in the candidate maintenance equipment as the third sequence maintenance equipment.

[0069] Optionally, the influence coefficient threshold can be adaptively set according to factors such as the space of the drawer in the maintenance equipment box and the number of maintenance equipment boxes. When the space of the drawer is large or the number of maintenance equipment boxes is sufficient, the influence coefficient threshold can be appropriately increased to reduce the weight of the box after packing, which is convenient for subsequent handling and use.

[0070] Step 1022 can more intuitively quantify the impact degree of a certain maintenance equipment on space by introducing an influence coefficient, providing a theoretical basis and guiding direction for selecting appropriate maintenance equipment for step-by-step containerization.

[0071] In step 1023, each maintenance equipment in the third sequence of maintenance equipment is sorted based on the type of the maintenance equipment.

[0072] After the screening by introducing the influence coefficient in step 1022, the remaining maintenance equipment has a relatively small volume. To place the maintenance equipment of the same type together as much as possible, the third sequence of maintenance equipment still needs to be sorted. The following methods can be used to sort the maintenance equipment in the third sequence of maintenance equipment:

[0073] The maintenance equipment in the third sequence of maintenance equipment is separated according to the sub-components to which they belong, and the maintenance equipment belonging to the same sub-component is grouped into one group; the maintenance equipment belonging to the same sub-component is grouped according to the equipment to which they belong, and the maintenance equipment belonging to the same equipment is grouped into one group.

[0074] During subsequent containerization, the maintenance equipment belonging to the same sub-component is preferentially containerized, and then the maintenance equipment belonging to the same equipment is containerized.

[0075] In steps 1021 to 1021 of the pre-containerization of maintenance equipment, through two screenings and one sorting, the maintenance equipment is divided into the first sequence of maintenance equipment, the second sequence of maintenance equipment, and the third sequence of maintenance equipment according to the containerization priority. Subsequently, the containerization of maintenance equipment can be carried out with reference to this priority.

[0076] In step 103, the maintenance equipment is containerized in the order from the first sequence of maintenance equipment to the third sequence of maintenance equipment and in various containerization methods.

[0077] In the actual application scenario, selecting an appropriate containerization method and grasping the principle of maximum space utilization rate are also necessary to consider and pay attention to during the concentration process of maintenance equipment.

[0078] This application provides three containerization methods: the containerization method along the Z-axis direction, the containerization method along the X-axis direction, and the mixed containerization method. The following is an explanation of the above three containerization methods respectively:

[0079] Figure 4 It is a schematic diagram of the space of the containerization method along the Z-axis direction provided by an embodiment of this application. Refer to Figure 4 An explanation of the containerization method along the Z-axis direction is given.

[0080] The three coordinates X, Y, and Z in the figure respectively represent the length, width, and height of the drawer in the maintenance equipment box. After the maintenance equipment P (the shaded part in the figure) is loaded into the drawer, according to the space division method, the remaining drawer space can be divided into the first space M, the second space L, and the third space R. Among them, the first space M is smaller than the second space L, and the second space L is smaller than the third space R.

[0081] When carrying out the containerization of maintenance equipment, it is carried out according to the principle of preferentially containerizing small spaces, that is, loading in the order of small spaces first and large spaces later.

[0082] Exemplarily, first fill the first space M with maintenance equipment of a suitable volume size; then, along the Z-axis direction from front to back, select maintenance equipment of a suitable volume size to fill the second space L; finally, fill the third space R. When filling the third space R, start from a place close to the origin O and load sequentially along the Z-axis direction;

[0083] According to such an order, it not only conforms to the containerization process in engineering applications but also meets the need for relatively regular distribution of maintenance equipment.

[0084] The containerization method along the X-axis direction is similar to that along the Z-axis direction, only the loading direction has changed.

[0085] The mixed containerization method is a mixed method of the containerization method along the X-axis direction and the containerization method along the Z-axis direction. It is an important loading method in the process of loading maintenance equipment. Since the loading volume may be too high when loading in a single direction strip, using the mixed loading method can leave a relatively large and complete remaining space block for the overall packing box, thus facilitating the improvement of space utilization rate.

[0086] This application also provides the principle of maximum space utilization rate. Exemplarily, the principle of maximum space utilization rate may include:

[0087] Containerize the first maintenance equipment with the largest bottom area as the bottom surface, the shortest side as the height, and the longest side perpendicular to the loading direction of the maintenance equipment.

[0088] Except for the first maintenance equipment, if the maintenance equipment can be containerized in multiple ways, the method with the smallest bottom area and the shortest side in the same direction as the maintenance equipment should be selected for containerization.

[0089] In step 103, the maintenance equipment containerization method provided by this application not only makes a priority determination based on the characteristics of the maintenance equipment but also introduces multiple containerization methods and the principle of maximum space utilization rate, providing guiding suggestions for improving the containerization efficiency and reducing the operation time of containerization personnel.

[0090] This application obtains relevant data of maintenance equipment, and based on the relevant data, conducts pre-packaging of the maintenance equipment through two screenings and one sorting. The maintenance equipment is respectively marked as the first-sequence maintenance equipment to the third-sequence maintenance equipment according to the packaging priority. Finally, based on the priority and various packaging methods, the maintenance equipment is packaged. This application provides a guiding method for packaging maintenance equipment, helping the packagers establish a spatial awareness of the maintenance equipment and the maintenance equipment boxes, and avoiding the problem of low space utilization rate of the maintenance equipment containers due to loading based on subjective experience.

[0091] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of this application.
