Description

Technical Field

[0001] The invention belongs to the technical field of logistics equipment production technology and relates to a preparation process of logistics equipment. Background Art

[0002] The current logistics equipment, such as various energy storage, equipment prefabricated cabins, modular buildings, environmentally friendly hazardous waste transport boxes and storage boxes, etc., mostly complete the entire production and manufacturing process through parts production, parts assembly, final assembly welding, weld grinding and paint spraying. For example, a Chinese patent with application number CN201710583451.6 provides a prefabricated equipment cabin, including a base, a side frame is provided on the base, a top cover is provided on the upper part of the side frame, the outer surface of the side frame is provided with a protective plate, the inner surface of the side frame is provided with an interior decoration plate, and the base, side frame and top cover form a cabin body.

[0003] Similar logistics equipment is manufactured and then subjected to external weatherproof test at the end. However, many new logistics equipment often contain multi-layered complex structures such as insulation layers. If the logistics equipment has leakage problems during the final stage of the weatherproof test, it is difficult to rework and repair it. At the same time, during the transportation, storage and on-site application of related industries such as energy storage, environmental protection and hazardous materials, there is often accumulation and leakage of internal liquid media, which is then discharged to the ground in an unorganized manner, which may cause pollution to the public environment. It is difficult to identify this problem with the existing external weatherproof test method.

[0004] In summary, the external wind and rain tightness test conducted after the existing logistics equipment is manufactured is not rigorous enough, nor is it safe and reliable enough, and there is much room for improvement. Summary of the invention

[0005] The purpose of the present invention is to propose a preparation process of logistics equipment in view of the above-mentioned problems existing in the prior art.

[0006] The object of the present invention can be achieved by the following technical scheme: A preparation process of logistics equipment, comprising the steps of:

[0007] S1: Assemble and weld the various parts to form the entire logistics equipment, and polish the welds to make the logistics equipment watertight;

[0008] S2: Before anti-corrosion spraying, water is stored in the logistics equipment and the water tightness of the logistics equipment is tested, and the logistics equipment that meets the water tightness requirements will proceed to the next process.

[0009] Preferably, in step S2, water is stored in the top cover of the logistics equipment and its water tightness is tested, and water is stored in the box of the logistics equipment and its water tightness is tested.

[0010] Preferably, in step S2, when the top cover of the logistics equipment is filled with water and its water tightness is tested, a plurality of flat plates are used to surround the top cover along the edge of the top cover, and the flat plates are connected with connectors, and then the pool structure formed by the flat plates and the top cover is filled with water, and it is checked from the inside of the logistics equipment whether there is water leakage from the top cover.

[0011] Preferably, in step S2, before water is stored in the pool structure formed by each flat plate and the top cover, a sealing gasket is arranged between the flat plate and the top cover to prevent water from leaking between the flat plate and the top cover, thereby misjudging the water tightness of the top cover.

[0012] Preferably, in step S2, when the box of the logistics equipment is filled with water and its water tightness is tested, the box is propped up, and water is directly added to the box or a local area of ​​the box, and it is checked from the outside of the logistics equipment whether there is water leaking from the inside of the box.

[0013] Preferably, the method further includes step S3: draining and drying the top cover and the box body of the logistics equipment to absorb residual moisture in the logistics equipment to prevent the anti-corrosion spray coating of the logistics equipment from failing.

[0014] Preferably, in step S3, the test water is recycled and reused, and after the test water for the water tightness test of the current logistics equipment is pumped away or sucked away, it is recycled and used for the water tightness test of the next logistics equipment.

[0015] Preferably, in step S3, before the detection water is recycled, the used water is filtered and purified to filter out impurities in the water.

[0016] Preferably, in step S2, the leaking parts of the top cover or the box body of the logistics equipment are marked, and the marked leaking parts are repaired.

[0017] Preferably, in step S2, after the marked leaking part is repaired, it is sent back and re-tested.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Added water tightness test for logistics equipment, so that the corresponding leakage points of logistics equipment can be discovered and solved in time during the manufacturing process, and it is easy for inspectors to observe and test, overcoming the problem that the external wind and rain tightness test carried out at the end of the existing technology is not rigorous, safe and reliable enough.

[0020] 2. Water can be stored in the logistics equipment and the water tightness of the logistics equipment can be tested. The impurities and dust generated by the processing of the logistics equipment can also be removed through the flow of testing water, which is equivalent to an additional cleaning of the logistics equipment, which is very convenient and practical.

[0021] 3. Water is stored in the top cover and the box of the logistics equipment respectively and their water tightness is tested, so that the two parts can be tested at the same time, which effectively shortens the time for checking the leakage points. It is also possible to deal with the leakage points in a targeted manner in time, overcoming the problem that the wind and rain tightness detection requires an overall investigation.

[0022] 4. When the pool structure formed by each flat plate and the top cover is used to store water, the top cover is used as the bottom plate of the pool structure. Therefore, the water tightness test of the top cover can be easily completed by simply checking from the inside of the logistics equipment whether there is water leakage from the top cover, and it is also easy to find the leakage point of the top cover.

[0023] 5. The box of the logistics equipment itself is a pool structure, so water can be directly stored. Then, the water tightness test of the box can be easily completed by checking from the outside of the logistics equipment to see if there is water leakage from the box. At the same time, the leakage effects of the sides and bottom of the box are different, so it is easy to find the leakage points of the box.

[0024] 6. When the logistics equipment is watertight and before anti-corrosion spraying, it is necessary to first pump out and dry the top cover and box of the logistics equipment, and absorb the residual moisture in the logistics equipment to prevent the anti-corrosion spraying treatment from failing due to residual moisture.

[0025] 7. The test water can be recycled repeatedly. After the test water for the water tightness test of the current logistics equipment is pumped away or sucked away, it can be recycled and used for the water tightness test of the next logistics equipment.

[0026] 8. The recycled test water will take away the impurities and dust generated by the logistics equipment processing during the test process. Therefore, before the test water is recycled, the used water needs to be filtered and purified in multiple ways to filter out the impurities in the water before it can be used for the next test.

If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0037] like Figure 1-Figure 3 As shown, a preparation process of logistics equipment includes the following steps:

[0038] S1: Assemble and weld the various parts to form the entire logistics equipment, and polish the welds to make the logistics equipment watertight;

[0039] S2: Before anti-corrosion spraying, water is stored in the logistics equipment and the water tightness of the logistics equipment is tested, and the logistics equipment that meets the water tightness requirements will proceed to the next process.

[0040] In the specific preparation process, logistics equipment still needs to go through a production and manufacturing process including parts manufacturing, parts assembly, final assembly welding, weld grinding and anti-corrosion spraying, but an additional watertightness test is added between the two processes of weld grinding and anti-corrosion spraying.

[0041] In this embodiment, a new watertightness test for logistics equipment is added, so that corresponding leakage points can be discovered and resolved in time during the manufacturing process of logistics equipment, and it is easy for inspectors to observe and inspect, thus overcoming the problem that the last external wind and rain tightness test conducted in the prior art is not rigorous enough and not safe and reliable enough.

[0042] The watertightness test can replace the wind and rain tightness test, but in the actual production and manufacturing process, according to the specific requirements of the logistics equipment production process, the logistics equipment as a whole is still subject to a wind and rain tightness test. These two processes have no interference and influence, but the watertightness test can replace the wind and rain tightness test and the wind and rain tightness test cannot replace the watertightness test.

[0043] It is also worth mentioning here that storing water in the logistics equipment and testing the watertightness of the logistics equipment can also remove the impurities and dust generated by the processing of the logistics equipment through the flow of testing water, which is equivalent to an additional cleaning of the logistics equipment, which is very convenient and practical.

[0044] like Figure 1 , Figure 2 As shown, on the basis of the above-mentioned embodiment, in step S2, water is stored in the top cover 110 of the logistics equipment and its water tightness is tested, and water is stored in the box body 120 of the logistics equipment and its water tightness is tested.

[0045] In a specific preparation process, the water tightness test of the logistics equipment can be divided into two steps. The top cover 110 and the box body 120 of the logistics equipment are respectively filled with water and tested for their water tightness, which more reasonably divides the logistics equipment into two parts for testing.

[0046] It is worth explaining here that in step S2, not only can the top cover 110 of the logistics equipment be stored with water and its water tightness be tested separately, but also the box body 120 of the logistics equipment can be stored with water and its water tightness can be tested separately. At the same time, since they are independent of each other and do not interfere with each other, the top cover 110 and the box body 120 of the logistics equipment can be stored with water and their water tightness can be tested at the same time.

[0047] In this embodiment, water is stored in the top cover 110 and the box body 120 of the logistics equipment and their water tightness is tested respectively, so that the two parts can be tested at the same time, which effectively shortens the time for checking the leakage points, and can also timely deal with the leakage points in a targeted manner, thus overcoming the problem that wind and rain tightness testing requires an overall check.

[0048] like Figure 1 , Figure 2 As shown, on the basis of the above-mentioned implementation mode, in step S2, when the top cover 110 of the logistics equipment is filled with water and its water tightness is tested, a plurality of flat plates 200 are used to surround the top cover 110 along the edge of the top cover 110, and the flat plates 200 are connected with connectors, and then the pool structure formed by the flat plates 200 and the top cover 110 is filled with water, and it is checked from the inside of the logistics equipment whether there is water leakage from the top cover 110.

[0049] In a specific preparation process, the shape of the top cover 110 may be a quadrilateral, a hexagon or other shapes. According to the actual shape of the top cover 110, a plurality of flat plates 200 may be arranged along the edge of the top cover 110 and above the top cover 110, and the flat plates 200 may be connected together with connectors.

[0050] In this embodiment, when the pool structure formed by each flat plate 200 and the top cover 110 is used to store water, the top cover 110 is used as the bottom plate of the pool structure. Therefore, it is only necessary to check from the inside of the logistics equipment (i.e., below the top cover 110) whether there is water leaking from the top cover 110 to conveniently complete the water tightness test of the top cover 110, and it is also easy to find the leakage point of the top cover 110.

[0051] like Figure 1 , Figure 2 As shown, on the basis of the above implementation, in step S2, before the water pool structure formed by each flat plate 200 and the top cover 110 is filled with water, a sealing gasket is set between the flat plate 200 and the top cover 110 to prevent water from leaking between the flat plate 200 and the top cover 110, thereby misjudging the water tightness of the top cover 110.

[0052] In this embodiment, since there is also a gap between the flat plate 200 and the top cover 110 , a sealing gasket is provided to seal the gap between the flat plate 200 and the top cover 110 to prevent water from leaking between the flat plate 200 and the top cover 110 , thereby misjudging the water tightness of the top cover 110 .

[0053] like Figure 1 , Figure 2 As shown, on the basis of the above-mentioned implementation mode, in step S2, when the box 120 of the logistics equipment is filled with water and its water tightness is tested, the box 120 is propped up, and water is directly stored in the box 120 or a local area of ​​the box 120, and it is checked from the outside of the logistics equipment whether there is water leaking from the inside of the box 120.

[0054] It is worth explaining here that since the box 120 structure of some logistics equipment is relatively complex and has multiple separate storage spaces, these local areas with separate storage spaces can also be tested for water storage. Therefore, water can be stored in these local areas separately, making the entire test more rigorous.

[0055] In this embodiment, the box body 120 of the logistics equipment itself is a water tank structure, so water can be directly stored. Then, the water tightness test of the box body 120 can be easily completed by checking from the outside of the logistics equipment whether there is water leakage from the box body 120. At the same time, the leakage effects of the sides and bottom of the box body 120 are different, so it is easy to find the leakage point of the box body 120.

[0056] like Figure 1 As shown, based on the above implementation, step S3 is also included: the top cover 110 and the box body 120 of the logistics equipment are drained and dried to absorb the residual moisture of the logistics equipment to prevent the anti-corrosion spray of the logistics equipment from failing.

[0057] In this embodiment, when the logistics equipment is well watertight and before anti-corrosion spraying is performed, the top cover 110 and the box body 120 of the logistics equipment need to be drained and dried, and the residual moisture in the logistics equipment needs to be sucked away to prevent the anti-corrosion spraying treatment from failing due to residual moisture.

[0058] like Figure 1 As shown, based on the above implementation, in step S3, the detection water is recycled and reused, and after the detection water for the water tightness detection of the current logistics equipment is pumped away or sucked away, it is recycled and used for the water tightness detection of the next logistics equipment.

[0059] In this embodiment, the detection water can be repeatedly recycled. After the detection water for the water tightness detection of the current logistics equipment is pumped away or sucked away, it is recycled and used for the water tightness detection of the next logistics equipment.

[0060] like Figure 1 As shown, based on the above implementation, in step S3, before the detection water is recycled, the used water is filtered and purified to filter out impurities in the water.

[0061] In this embodiment, the recycled test water will carry away impurities and dust generated by the logistics equipment processing during the test process. Therefore, before the test water is recycled, the used water needs to be filtered and purified in multiple ways to filter out impurities in the water before it can be used for the next test.

[0062] like Figure 1As shown, based on the above implementation, in step S2, the leaking part of the top cover 110 or the box body 120 of the logistics equipment is marked, and the marked leaking part is repaired.

[0063] In this embodiment, water leakage from the top cover 110 or the box body 120 can be easily found by inspection. The corresponding leakage points are first marked, and after the logistics equipment is drained and dried, the marked leakage parts are repaired.

[0064] like Figure 1 As shown, based on the above implementation mode, in step S2, after the marked leaking part is repaired, it is sent back and re-tested.

[0065] In this embodiment, after the marked leaking part is repaired, it is sent back and re-tested. The secondary test is the same as the previous watertightness test, but only water is stored in the marked parts in the top cover 110 or the box 120 of the logistics equipment and its watertightness is tested.

[0066] from Figure 1 , Figure 2 As shown, in terms of the overall preparation process, step S1 is first performed: assembling and welding the various components to form a complete logistics equipment, and polishing the welds to make the logistics equipment have good water tightness.

[0067] Then proceed to step S2: before anti-corrosion spraying, the top cover 110 of the logistics equipment is filled with water and its water tightness is tested. A plurality of flat plates 200 are used to surround the top cover 110 along the edge of the top cover 110, and the flat plates 200 are connected with connectors. Then, water is stored in the pool structure formed by the flat plates 200 and the top cover 110, and it is checked from the inside of the logistics equipment whether there is water leakage from the top cover 110; at the same time, water is stored in the box 120 of the logistics equipment and its water tightness is tested. The box 120 is propped up, and water is directly stored in the box 120 or a local area of ​​the box 120, and it is checked from the outside of the logistics equipment whether there is water leakage from the inside of the box 120. Among them, for logistics equipment with poor water tightness and leakage, the leaking part of the top cover 110 or the box 120 of the logistics equipment is marked, the marked leaking part is repaired, and after the marked leaking part is repaired, it is sent back and re-tested.

[0068] Then, step S3 is performed: the top cover 110 and the box body 120 of the logistics equipment are drained and dried to absorb the residual moisture of the logistics equipment to prevent the anti-corrosion spray of the logistics equipment from failing.
