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 of correcting deformation and non-standard operation in light deck explosive operation in the prior art, which leads to secondary operation of the deck in the later period, the present application provides a deck explosive correction device which can improve the efficiency of correcting deformation.

[0044] As shown in Figure 1 The deck explosive correction device includes a support structure 1, a measurement structure 3 and a correction structure 2. The support structure 1 is arranged above the deck 100 and fixedly connected with the deck 100. The correction structure 2 is installed on the support structure 1, and the correction structure 2 is arranged directly above the deck 100. The correction structure 2 includes a lifting assembly 21 and a correction assembly 22. The lifting assembly 21 is fixedly connected with the support structure 1, and the correction assembly 22 is connected with the lifting assembly 21 for pushing or pulling the deck 100 to correct the deck 100. The measurement structure 3 is installed on the support structure 1 to measure the lifting or lowering distance of the correction assembly 22.

[0045] The deck firework correction device provided by the application, since the correction assembly 22 is connected with the lifting assembly 21, the lifting assembly 21 can drive the correction assembly 22 to move relative to the deck 100, since the correction assembly 22 is used for pushing or pulling the deck 100 to correct the deck 100, in addition, the measuring structure 3 can measure the rising or falling distance of the correction assembly 22, which ensures the accuracy of correcting the deformation of the deck 100, effectively avoids the repeated rework condition, improves the work quality, and further can improve the correction efficiency, the deck firework correction device can reduce the number of operators and operation difficulty, and improve the work efficiency.

[0046] The deck 100 has a main body 101 and support beams 102 arranged at the bottom of the main body 101, a plurality of support beams 102 are equidistantly arranged, for example, the support beam 102 is a spherical flat steel.

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

[0048] In some embodiments, as shown in Figures 3 to 5 The correction assembly 22 includes a limiting column 221, a pressure plate 222, a pressure rod 223 and a connecting rod 224, the pressure plate 222 is arranged between the limiting column 221 and the pressure rod 223, the upper and lower ends of the pressure plate 222 are fixedly connected with the limiting column 221 and the pressure rod 223 respectively, the connecting rod 224 is located at the top of the pressure rod 223 and is detachably connected with the lifting assembly 21, and the pressure plate 222 is used for pressing the protrusion of the deck 100, and the limiting column 221 can pass through the binding hole of the deck 100 and the limiting beam limiting hole 111 of the limiting beam 11. When the correction assembly 22 is driven to move 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, and the deck 100 is corrected.

[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 direction of the protrusion, so as to correct the deformation.

[0050] The limiting beam limiting hole 111 is provided with a limiting part 13 capable of limiting the one-way movement of the limiting column 221. Two opposite side walls of the limiting column 221 have a plurality of spaced tooth parts, adjacent tooth parts form a tooth groove, the limiting part 13 includes a blocking arm 131, the blocking arm 131 is arranged on the side of the limiting column 221 and can be clamped into the tooth groove, the blocking arm 131 is located in the limiting beam limiting hole 111, and the limiting column 221 can be one-way moved under the action of the blocking arm 131.

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

[0052] The limiting column 221 needs to be restored to the original position after work, in order to enable the limiting column 221 to quickly restore the position and enable the blocking arm 131 to play a limiting role, in some embodiments, the two blocking arms 131 are connected by an elastic member 134 to enable the two blocking arms 131 to approach each other to clamp and limit the limiting column 221. For example, the elastic member 134 is a spring.

[0053] Specifically, the two ends of the blocking arm 131 pass through the limiting beam 11, one end of the blocking arm 131 is provided with an unlocking handle 132, and the other end of the blocking arm 131 is provided with a connecting arm 133. The two connecting arms 133 are connected by an elastic member 134 to always have a tendency to approach each other. One side of the limiting beam 11 is provided with two first through holes, one end of the blocking arm 131 provided with the unlocking handle 132 passes through the first through hole, and the other side of the limiting beam 11 is provided with two long strip-shaped second through holes, and the other end of the two blocking arms 131 passes through the corresponding second through hole.

[0054] When the limiting 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 drive the blocking arms 131 away from each other to release the limiting column 221, so that the limiting column 221 can move bidirectionally. When the limiting column 221 returns to the initial position, the limiting column 221 is again limited, so that the limiting column 221 can only move unidirectionally.

[0055] In other embodiments, the limiting part 13 includes a pawl which is located in the limiting beam limiting hole 111 and movably mounted on the hole wall of the limiting beam limiting hole 111. The pawl is mounted in the hole wall of the limiting beam limiting hole 111 by a torsion spring, so that the pawl rotates relative to the limiting column 221 under the extrusion of the limiting column 221 when the limiting column 221 moves. When the limiting column 221 moves, the end of the pawl can enter the tooth groove, and when the limiting column 221 moves in the opposite direction, the pawl is clamped in the tooth groove to achieve the purpose of one-way limiting of the limiting column 221.

[0056] Of course, in other embodiments, as shown in Figure 6 and Figure 7 , the correction assembly 22 includes a zipper 225 and a pull hook 226. The two ends of the zipper 225 are respectively connected with the lifting assembly 21 and the pull hook 226. The pull hook 226 can pass through the binding hole of the deck 100. The lifting assembly 21 works to move the zipper 225 upward, which in turn drives the pull hook 226 to move upward. The upward movement of the pull hook 226 will pull the deck 100 upward, thereby correcting the downwardly recessed deck 100.

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

[0058] Specifically, as shown in Figure 3 , Figure 8 and Figure 9 , the turntable 123 is fixedly connected with 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 connecting hole 1231. The support beam 122 is provided with a connecting column 124 which passes through the turntable connecting hole 1231 to connect the support beam 122 with the lifting assembly 21. The connecting column 124 can be a threaded column which is fixed on the support beam 122 by cooperating with a nut. In this way, the lifting assembly can be easily disassembled and replaced, which is convenient for maintenance and reduces the use and maintenance costs.

[0059] Since the lifting assembly will rotate when 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 to the support beam 122 so as to limit the lifting assembly 21. This ensures that the lifting assembly 21 is fixed in position and does not rotate relative to the support beam 122. In addition, there is only one beam limiting hole 1221 and multiple turntable limiting holes 1232. The multiple beam limiting holes 1221 are arranged along the circumference of the turntable 123 to ensure that the turntable 123 can adapt to the different rotation angles of the correction structure 2. This facilitates the disassembly and replacement of the correction assembly 22, facilitates maintenance, and reduces usage and maintenance costs.

[0060] like Figure 7 As shown, a measuring structure 3 is mounted at least on the support beam 122 to measure the distance the correction assembly 22 is raised or lowered. For example, the measuring structure 3 is a measuring tape, which measures the height of the lifting assembly 21 to determine whether the correction assembly 22 is rising or falling. In other embodiments, the measuring structure 3 can also be a laser rangefinder. The measuring structure 3 ensures the accuracy of the correction deck 100 deformation, effectively avoiding repeated rework and improving 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 contraction 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 Figure 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 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 end of the screw rod 215 away from the upper support arm 211 is connected to the lifting handle 216, the two upper support arms 211 are connected to the turntable 123, and the two lower support arms 212 are connected to the 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 hook 1211 can be multiple, and the hook 1211 can be used to hook a water gun and a fire gun, which provides convenience for fire workers, enhances the comfort of operation, and improves work efficiency and operation safety.

[0064] The deck firework correction method is applied to the deck firework correction device provided in the embodiment of the present application, as shown in the figure, and the method comprises the following steps: Figure 10

[0065] S101, obtain the deformation amount and deformation direction of the deck 100, and select the correction assembly 22 according to the deformation direction;

[0066] S102, pass the correction assembly 22 through the binding hole of the deck 100;

[0067] S103, if the deck 100 is concave downward, the lifting assembly 21 pulls the correction assembly 22, and if the deck 100 is convex upward, the lifting assembly 21 presses the correction assembly 22 downward, and when the lifting assembly 21 pulls or presses the correction assembly 22, the measuring structure 3 measures the lifting or lowering distance of the correction assembly 22, and if the distance is a preset distance, the lifting assembly 21 stops lifting or lowering.

[0068] The method provided in the present application can drive the correction assembly 22 to move relative to the deck 100, and since the correction assembly 22 is used to push or pull the deck 100 to correct the deck 100, in addition, the measuring structure 3 can measure the lifting or lowering distance of the correction assembly 22, which ensures the accuracy of correcting the deformation of the deck 100, effectively avoids the situation of repeated rework, improves the work quality, and further improves the correction efficiency, and the deck firework correction device can reduce the number of operators and operation difficulty, and improve the work efficiency.

[0069] More specifically, as shown in the figure, the method specifically comprises the following steps: Figure 11

[0070] S201, obtain the deformation amount and deformation direction of the deck 100, and select the correction assembly 22 according to the deformation direction;

[0071] S202, when the deck 100 is concave downward, the draw hook 226 is hooked on the binding hole of the deck 100, the lifting assembly 21 is operated to move the draw hook 226 connected with the lifting assembly 21 upward to drive the draw hook 226, when the zipper 225 is tightened, the deformation amount is corrected according to the need, the extension and retraction amount of the lifting assembly 21 obtained by the observation measuring structure 3 is observed, and the concave deformation correction is realized;

[0072] ​​S203、When the deck 100 is convex upward, the limiting column 221 is inserted into the limiting hole of the limiting beam 11 through the binding hole, and under the cooperation of the elastic member 134 and the blocking arm 131, the limiting column 221 is limited to move downward only, and then the limiting beam 11 is fixed on the supporting beam 102 through the positioning bolt 5; the limiting column 221 is moved downward by operating the lifting assembly 21 until the pressure plate 222 on the limiting column 221 contacts with the deck 100, the measuring structure 3 measures the lifting or lowering distance of the correcting assembly 22, if the distance is the preset distance, the lifting assembly 21 stops lifting or lowering; when the convex deformation correction is finished, the unlocking handle 132 is turned to the direction of the limiting column 221, the blocking arm 131 is unlocked, and the limiting column 221 is separated from the limiting hole 111.

[0073] In addition, the above are only the preferred embodiments of the present application and the applied technical principles. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and those skilled in the art can make various obvious changes, readjustments and substitutions without departing from the protection scope of the present application.
