[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] In order to solve the problem of low efficiency in deformation correction and irregular operation in light deck pyrotechnics in the prior art, which leads to the need for secondary operation of the deck in the later stage, the present invention provides a deck pyrotechnics correction device, which can improve the efficiency of deformation correction.

[0044] like Figure 1 As shown, the deck pyrotechnic correction device includes a supporting structure 1, a measuring structure 3 and a correction structure 2. The supporting structure 1 is arranged above the deck 100 and fixedly connected to the deck 100; the correction structure 2 is installed on the supporting structure 1. The correction structure 2 is arranged directly above the deck 100. The correction structure 2 includes a lifting component 21 and a correction component 22. The lifting component 21 is fixedly connected to the supporting structure 1. The correction component 22 is connected to the lifting component 21 for pushing or pulling the deck 100 to correct the deck 100. The measuring structure 3 is installed on the supporting structure 1 to measure the rising or falling distance of the correction component 22.

[0045] The deck pyrotechnic correction device provided by the present invention has a correction component 22 connected to a lifting component 21, and the lifting component 21 can drive the correction component 22 to move relative to the deck 100. Since the correction component 22 is used to push or pull the deck 100 to correct the deck 100, and the measuring structure 3 can measure the rising or falling distance of the correction component 22, the accuracy of correcting the deformation of the deck 100 is ensured, and repeated rework is effectively avoided, thereby improving the work quality and the correction efficiency. The deck pyrotechnic correction device can reduce the number of operators and the difficulty of operation, and improve work efficiency.

[0046] The deck 100 has a main body 101 and a support beam 102 disposed at the bottom of the main body 101 . A plurality of support beams 102 are disposed at equal intervals. For example, the support beams 102 are bulb flat steels.

[0047] In some embodiments, Figure 2 As shown, the support structure 1 includes a limiting beam 11 and a supporting gantry 12, wherein the limiting beam 11 is fixed to the bottom of the weld of the deck 100, and the supporting gantry 12 is installed on the top of the deck 100. Specifically, the two ends of the limiting beam 11 are respectively fixedly connected to two adjacent support beams 102, and the support beams 102 and the limiting beam 11 are fixedly connected by positioning bolts 5. The two support beams 102 are located in the area surrounded by the limiting beams 11, thereby ensuring the reliability of the connection between the support beams 102 and the limiting beams 11, and ensuring that the two can be connected smoothly.

[0048] In some embodiments, Figures 3 to 5 As shown, the correction assembly 22 includes a limit column 221, a pressure plate 222, a pressure rod 223 and a connecting rod 224. A pressure plate 222 is arranged between the limit column 221 and the pressure rod 223. The upper and lower ends of the pressure plate 222 are respectively fixedly connected to the limit column 221 and the pressure rod 223. The connecting rod 224 is located at the top of the pressure rod 223 and is detachably connected to the lifting assembly 21. The pressure plate 222 is used to press down the protrusion of the deck 100. The limit column 221 can pass through the lashing hole of the deck 100 and the limit beam limit hole 111 of the limit beam 11. When the correction assembly 22 is driven downward by the lifting assembly 21, the pressure plate 222 is located above the deck 100, so that the pressure plate 222 presses the protrusion of the deck 100 to correct the deck 100.

[0049] It should be noted that, whether the deck 100 is concave downward or convex upward, it can be corrected by the pressure plate 222. The moving direction of the pressure plate 222 is opposite to the convex direction to correct the deformation.

[0050] A limiting portion 13 capable of limiting the unidirectional movement of the limiting column 221 is arranged in the limiting hole 111 of the limiting beam. The two opposite side walls of the limiting column 221 have a plurality of spaced teeth, and adjacent teeth form tooth grooves. The limiting portion 13 includes a blocking arm 131, which is arranged on the side of the limiting column 221 and can be inserted into the tooth groove. The blocking arm 131 is located in the limiting hole 111 of the limiting beam, and the limiting column 221 can realize unidirectional movement under the action of the blocking arm 131.

[0051] Specifically, there are two blocking arms 131, which are respectively located on the side walls of the limiting column 221 and can be inserted into the tooth groove. Compared with one blocking arm 131, two blocking arms 131 can be simultaneously limited from both sides of the limiting column 221 to improve the limiting reliability of the limiting column 221 and avoid deformation of a single blocking arm 131 and failure of limiting.

[0052] After the work of the limiting column 221 is completed, it needs to be restored to its original position. In order to enable the limiting column 221 to quickly restore its position and enable the blocking arm 131 to serve the purpose of limiting, in some embodiments, the two blocking arms 131 are connected by an elastic member 134 so that the two blocking arms 131 can be close to each other to clamp and limit the limiting column 221. For example, the elastic member 134 is a spring.

[0053] Specifically, both ends of the blocking arm 131 pass through the limiting beam 11, an unlocking handle 132 is provided at one end of the blocking arm 131, and a connecting arm 133 is provided at the other end of the blocking arm 131, and the two connecting arms 133 are connected by an elastic member 134 so as to always have a tendency to approach each other. Two first through holes are provided on one side of the limiting beam 11, and an unlocking handle 132 is provided at one end of the blocking arm 131 passing through the first through holes, while two long strip-shaped second through holes are provided on the other side of the limiting beam 11, and the other ends of the two blocking arms 131 pass through the corresponding second through holes respectively.

[0054] When the limit column 221 needs to be released to return to the initial position, the two connecting arms 133 are directly pushed away from each other, and then the connecting arms 133 will drive the blocking arms 131 to move away from each other to release the limit column 221, so that the limit column 221 can move in both directions. When the limit column 221 returns to the initial position, the limit column 221 will be limited again, so that the limit column 221 can only move in one direction.

[0055] In some other embodiments, the limiting portion 13 includes a pawl, which is located in the limiting hole 111 of the limiting beam and can be movably installed in the hole wall of the limiting hole 111 of the limiting beam. The pawl is installed in the hole wall of the limiting hole 111 of the limiting beam through a torsion spring, so that when the limiting column 221 moves, the pawl rotates relatively under the squeezing of the limiting column 221. When the limiting column 221 moves, the end of the pawl can enter the tooth groove, and when it moves in the opposite direction to the limiting column 221, the pawl is stuck in the tooth groove to achieve the purpose of unidirectional limiting of the limiting column 221.

[0056] Of course, in other embodiments, such as Figure 6 and Figure 7 As shown, the correction component 22 includes a zipper 225 and a hook 226. The two ends of the zipper 225 are connected to the lifting component 21 and the hook 226 respectively. The hook 226 can pass through the lashing hole of the deck 100. When the lifting component 21 works, the zipper 225 moves up, which in turn drives the hook 226 to move upward. When the hook 226 moves upward, the deck 100 is pulled upward, so that the sunken deck 100 can be corrected.

[0057] In some embodiments, Figure 8 As shown, the support gantry 12 includes a support column 121 and a support beam 122. The support beam 122 is connected to the lifting component 21 through a turntable 123. The two ends of the support beam 122 are respectively connected to the two support columns 121, and the support beam 122 is located on the top of the two support columns 121. In this way, the lifting component 21 can be fixed at a certain height. The support column 121 is fixedly connected to the deck 100, so that the deck 100 can provide support for the support column 121.

[0058] Specifically, combined Figure 3 , Figure 8 and Fig. 9 As shown, the turntable 123 is fixedly connected to the lifting assembly 21. For example, the turntable 123 and the lifting assembly 21 can be connected by fasteners, or the turntable 123 and the lifting assembly 21 can be connected by welding. The turntable 123 has a turntable connection hole 1231, and the support beam 122 is provided with a connection column 124. The connection column 124 passes through the turntable connection hole 1231 to connect the support beam 122 to the lifting assembly 21. Among them, the connection column 124 can be a stud, and the lifting assembly is fixed on the support beam 122 by the cooperation of the nut and the stud, which is convenient for disassembly and replacement, convenient for maintenance, and reduces the use and maintenance costs.

[0059] Since the lifting assembly will rotate after being subjected to tension or thrust, in some embodiments, the support beam 122 is provided with a beam limiting hole 1221, and the turntable 123 is provided with a turntable limiting hole 1232. The limiting bolt 4 passes through the beam limiting hole 1221 and the turntable limiting hole 1232 to connect the lifting assembly 21 with the support beam 122 to limit the lifting assembly 21, so as to ensure that the position of the lifting assembly 21 is fixed and will not rotate relative to the support beam 122. In addition, there is one beam limiting hole 1221 and a plurality of turntable limiting holes 1232, and the plurality of beam limiting holes 1221 are arranged along the circumference of the turntable 123 to ensure that the turntable 123 can adapt to the requirements of different rotation angles of the correction structure 2, so as to facilitate the disassembly and replacement of the correction assembly 22, facilitate maintenance, and reduce the use and maintenance costs.

[0060] like Figure 7 As shown, the measuring structure 3 is at least installed on the supporting beam 122 to measure the rising or falling distance of the correction component 22. For example, the measuring structure 3 is a measuring tape, and the height of the lifting component 21 is measured by the measuring tape to determine whether the correction component 22 is rising or falling. In some other embodiments, the measuring structure 3 can also be a laser rangefinder. The measuring structure 3 ensures the accuracy of the deformation of the correction deck 100, effectively avoids repeated rework, and improves the work quality.

[0061] The amount of correction deformation is proportional to the lifting height of the lifting component 21. Therefore, when correcting the deck 100, it is necessary to correct the deformation as needed and observe the extension and retraction of the measuring tape to drive the lifting component 21 to work and realize the correction of the concave deformation.

[0062] In some embodiments, continue to refer to Fig. 9 The lifting assembly 21 is a scissor-type jack, which includes an upper support arm 211, a lower support arm 212, a support hinge shaft 213, a top head 214, a screw rod 215 and a lifting handle 216, wherein the upper support arm 211 and the lower support arm 212 are connected by the support hinge shaft 213 and the screw rod 215, and the lifting handle 216 is connected to the end of the screw rod 215 away from the upper support arm 211. The two upper support arms 211 are connected to the turntable 123, and the two lower support arms 212 are connected to the top head 214. The specific use and working principle of the scissor-type jack are existing technologies and will not be described in detail here.

[0063] like Figure 8 As shown, the side wall of the support column 121 is provided with a hook 1211. The number of the hooks 1211 can be multiple, and the hooks 1211 can be used to hook water guns and fire guns, which provides convenience for fire workers, enhances the comfort of operation, and improves work efficiency and operation safety.

[0064] The deck pyrotechnic correction method described in the present invention is applied to the deck pyrotechnic correction device provided in the embodiment of the present invention, such as Fig.10 As shown, the method comprises the following steps:

[0065] S101, obtaining the deformation amount and deformation direction of the deck 100, and selecting the correction component 22 according to the deformation direction;

[0066] S102, partially passing the correction component 22 through the lashing hole of the deck 100;

[0067] S103. If the surface of the deck 100 is concave downward, the lifting component 21 pulls up the correction component 22. If the surface of the deck 100 is convex upward, the lifting component 21 presses down the correction component 22. When the lifting component 21 pulls up or presses down the correction component 22, the measuring structure 3 measures the rising or falling distance of the correction component 22. If the distance is the preset distance, the lifting component 21 stops rising or falling.

[0068] In the method provided by the present invention, the lifting component 21 can drive the correction component 22 to move relative to the deck 100. Since the correction component 22 is used to push or pull the deck 100 to correct the deck 100, and the measuring structure 3 can measure the rising or falling distance of the correction component 22, the accuracy of correcting the deformation of the deck 100 is ensured, and repeated rework is effectively avoided, thereby improving the work quality and improving the correction efficiency. The deck pyrotechnic correction device can reduce the number of operators and the difficulty of operation, and improve work efficiency.

[0069] More specifically, Fig.11 As shown, the method specifically comprises the following steps:

[0070] S201, obtaining the deformation amount and deformation direction of the deck 100, and selecting the correction component 22 according to the deformation direction;

[0071] S202, when the deck 100 is sunken downward, hook the hook 226 to the lashing hole of the deck 100, operate the lifting assembly 21 to make the hook 226 connected to the lifting assembly 21 move upward, drive the hook 226, and when the zipper 225 is tightened, correct the deformation as needed, observe the expansion and contraction amount of the lifting assembly 21 obtained by the measuring structure 3, and realize the correction of the sunken deformation;

[0072] S203. When the deck 100 surface bulges upward, the limit column 221 is passed through the binding hole and inserted into the limit hole of the limit beam 11. Under the coordinated action of the elastic member 134 and the stop arm 131, the limit column 221 is restricted to move downward, and then the limit beam 11 is fixed to the support beam 102 by the positioning bolt 5; the limit column 221 is moved downward by operating the lifting assembly 21 until the pressure plate 222 on the limit column 221 contacts the deck 100 surface, and the measuring structure 3 measures the rising or falling distance of the correction assembly 22. If the distance is the preset distance, the lifting assembly 21 stops rising or falling; when the bulge deformation correction is completed, the unlocking handle 132 is rotated in the direction of the limit column 221, the stop arm 131 is unlocked, and the limit column 221 is pulled out of the limit hole 111.

[0073] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
