[0002] The fourth category of vaults is a type of business vault in a bank. In order to properly keep valuables and cash, banks usually have four categories of vaults for storing valuables and cash.

[0003] In the prior art, in order to ensure the safety of valuables and cash, the fourth category of lockers needs to have a high degree of security, so their structures are usually designed to be relatively thick and sturdy; and in order to facilitate the production and assembly of the fourth category of lockers, the fourth category of lockers are usually composed of multiple steel plates. When combining these steel plates, they are usually fixed together by welding.

[0004] However, the four types of libraries formed by the above-mentioned combined steel plates still have the following defects during the processing and welding process:

[0005] Since the steel plates are relatively thick, the high-temperature zone during heating is large and the cooling rate is slow, which leads to an increase in the plastic deformation zone in the joint area, making it easy for large deformation to occur during combined welding of the steel plates, affecting their use. Summary of the invention

[0023] Beneficial effects of the present invention:

[0024] 1. By setting the first bevel, the second bevel, the convex part, the cylindrical block and the groove, when two steel plates are spliced, two V-shaped welds for welding are formed, so that during welding, the two V-shaped welds can be welded separately to achieve step-by-step welding, reduce the welding thickness during each welding, and thus ensure the welding effect; through the cylindrical structure of the cylindrical block, during the welding process, the two steel plates can be driven to rotate a certain angle along the axis of the cylindrical block to adapt to the expansion deformation of welding; they can be positioned at a certain angle before welding, and continuously rotated during the welding process until the two steel plates are rotated to the same plane after the welding is completed, so as to achieve the purpose of rotation welding and further improve the welding effect;

[0025] 2. By setting an angle adjustment mechanism, it should be noted that when in use, the lifting mechanism drives the two connecting rods to rise and fall synchronously, thereby driving the rotating shaft to rise and fall, so as to achieve the purpose of adjusting the position of the rotation point between the two mounting frames, and then when one of the steel plates is driven to rotate by the rotating drive mechanism, the steel plate can rotate along the axis of the cylindrical block;

[0026] 3. By setting a supporting mechanism, during the rising process of the rotating shaft, the telescopic airbag is pulled to expand, so that negative pressure is generated in the telescopic airbag, and then the one-way valve is automatically opened. When the height adjustment of the rotating shaft is completed, the one-way valve is closed, so that the telescopic airbag is sealed. Then, when the threaded rod generates downward pressure, that is, the weight of the steel plate is too large to squeeze the threaded rod, the threaded rod will squeeze the telescopic airbag at this time, and then the telescopic airbag can provide an upward supporting force for the threaded rod to relieve the pressure on the thread teeth on the threaded rod and prevent damage due to excessive pressure;

[0027] 4. By setting a position display mechanism, during the rising process of the threaded rod, the telescopic airbag continuously expands, absorbs the oil in the connecting pipe, causing the oil in the connecting pipe to drop. When it is observed that the scale data corresponding to the top of the oil is the same as the measured weld depth, it is judged that the rotating shaft coincides with the axis of the cylindrical block; that is, by setting the position display mechanism, the convenience and accuracy of adjustment are improved.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1-3 As shown, a four-category warehouse includes a business warehouse surrounded by multiple steel plates 1, and welds are formed between adjacent steel plates 1 by welding; the upper and lower sides of the steel plate 1 are respectively provided with a first bevel 2 and a second bevel 3, and a convex portion 4 is formed between the first bevel 2 and the second bevel 3; when two steel plates 1 are combined, the convex portions 4 on the two steel plates 1 are in contact with each other, so that V-shaped welds for welding are formed on the upper and lower sides of the two steel plates 1; cylindrical blocks 5 are arranged at intervals on the convex portion 4 of one of the steel plates 1, and grooves 6 adapted to the cylindrical blocks 5 are arranged at intervals on the convex portion 4 of the other steel plate 1; when the two steel plates 1 are combined and welded, the cylindrical block 5 is inserted into the groove 6, and the steel plate 1 can rotate along the axis of the cylindrical block 5.

[0045] It should be noted that when two steel plates 1 are combined, two V-shaped welds are formed for welding, so that during welding, the two V-shaped welds can be welded separately to achieve step-by-step welding, reduce the welding thickness during each welding, and thus ensure the welding effect;

[0046] By using the cylindrical block 5 and the groove 6 in coordination, when the two steel plates 1 are spliced, the cylindrical block 5 is inserted into the groove 6, and the splicing alignment is automatically achieved to prevent the misalignment problem during welding; and by the cylindrical structure of the cylindrical block 5, during the welding process, the two steel plates 1 can be driven to rotate a certain angle along the axis of the cylindrical block 5 to adapt to the expansion deformation of welding; they can be positioned at a certain angle before welding, and continuously rotated during the welding process until the welding is completed, and the two steel plates 1 are rotated to the same plane to achieve the purpose of rotational welding and further improve the welding effect; and the V-shaped weld on the other side can be welded after a certain interval of time, at which time the thickness of the steel plate 1 welding is greatly shortened to ensure the welding effect.

[0047] like Figure 1-13 As shown, a processing method of four types of libraries includes the following steps:

[0048] Step 1: Steel plate positioning: First, assemble and splice the two steel plates 1, insert the cylindrical block 5 into the groove 6, so that the two steel plates 1 are automatically aligned and spliced; then the positions of the two steel plates 1 are locked by the positioning mechanism 7, at which time the two steel plates 1 are in the same plane, and the upper and lower sides of the two steel plates 1 form a V-shaped weld for welding;

[0049] Step 2, rotational welding: Use welding equipment to weld the weld between the two steel plates 1, and during the welding process of one of the V-shaped welds, drive one of the steel plates 1 to rotate along the axis of the cylindrical block 5 through the angle adjustment mechanism 8, so that the V-shaped weld at the welding point gradually decreases, while the V-shaped weld on the other side increases relatively, so that as the welding heat increases, the weld on the other side increases to increase the expansion space; after completing the welding work of the V-shaped weld position on one side, weld the V-shaped weld position on the other side, and thus complete the welding work of the entire steel plate 1.

[0050] like Figure 1-4 As shown, the positioning mechanism 7 includes a mounting frame 71, a clamping plate 72 and a linear drive mechanism 73; a plurality of clamping plates 72 are slidably connected to the mounting frame 71, and the linear drive mechanism 73 is installed on the mounting frame 71; the linear drive mechanism 73 is used to drive the clamping plates 72 to slide, and the steel plate 1 is clamped at a position between the plurality of clamping plates 72; it can be understood that the linear drive mechanism 73 is a prior art, and its installation method and structure are not limited, as long as it can achieve driving 72 to slide reciprocatingly along a straight line, such as an electric telescopic rod.

[0051] It should be noted that, first, the two steel plates 1 are spliced ​​and placed on a horizontal mounting frame 71, and then the multiple clamps 72 are driven to move by a linear drive mechanism 73, and the steel plates 1 are positioned and clamped from different sides of the steel plates 1 by the multiple clamps 72; by driving the clamps 72 on the opposite sides to move, the connection position between the two steel plates 1 can be adjusted horizontally.

[0052] like Figure 1-5 As shown, the positioning mechanism 7 includes at least two mounting frames 71; the angle adjustment mechanism 8 is used to drive at least one mounting frame 71 to rotate; the angle adjustment mechanism 8 includes a height adjustment mechanism and a rotation drive mechanism 86; the height adjustment mechanism is used to adjust the height of the rotation point between the two mounting frames 71; the rotation drive mechanism 86 is used to drive one of the mounting frames 71 to rotate.

[0053] It should be noted that after the two steel plates 1 are spliced ​​and positioned, the height of the rotation point between the two mounting frames 71 is adjusted through the height adjustment structure so that the rotation point between the two mounting frames 71 coincides with the axis of the cylindrical block 5; then the rotation drive mechanism 86 is used to drive one of the steel plates 1 to rotate upward to a certain angle, and welding work can be carried out at this time. During the welding process, one of the steel plates 1 is driven by the rotation drive mechanism 86 to continuously rotate and reset until the welding is completed, and the two steel plates 1 are just in the same plane, thereby achieving the purpose of rotational welding.

[0054] like Figure 1-4 and Figure 6-7As shown, the height adjustment mechanism includes a connecting rod 81, a rotating shaft 82, a support frame 83 and a lifting mechanism 85; the support frame 83 is arranged on one of the mounting frames 71, and a pair of first vertical slide grooves 84 are opened on the second bevel 3, and the two ends of the rotating shaft 82 are slidably connected to the first vertical slide grooves 84, and the axis of the cylindrical block 5 and the axis of the first vertical slide groove 84 are in the same vertical plane, and the two connecting rods 81 are coaxially rotatably connected to the rotating shaft 82; the lifting mechanism 85 is used to drive the two connecting rods 81 to rise and fall synchronously.

[0055] It should be noted that, when in use, the two connecting rods 81 are driven to rise and fall synchronously by the lifting mechanism 85, thereby driving the rotating shaft 82 to rise and fall until the axis of the rotating shaft 82 coincides with the axis of the cylindrical block 5, so as to achieve the purpose of adjusting the position of the rotation point between the two mounting frames 71, and then when one of the steel plates 1 is driven to rotate by the rotating driving mechanism 86, the steel plate 1 can rotate along the axis of the cylindrical block 5;

[0056] When the drive shaft 82 is raised or lowered, the shaft 82 slides in the first vertical slide groove 84 on the support frame 83, which can prevent the shaft 82 from shifting during the movement and provide support for the shaft 82 in directions other than the vertical direction, thereby providing stable support for the welding of heavy steel plates 1 and improving the stability of use.

[0057] like Figure 6-7 As shown, the lifting mechanism 85 includes a sleeve 851, a threaded rod 852, a worm wheel 853, a worm 854, a guide mechanism 856 and a linkage mechanism 857; the two sleeves 851 are respectively arranged on the two mounting frames 71 (such as Figure 4 As shown in the figure, the worm wheel 853 is arranged on the sleeve 851, the worm wheel 853 is threadedly sleeved on the threaded rod 852, the worm 854 is rotatably connected to the sleeve 851, and the worm 854 is meshed with the worm wheel 853; when the worm 854 rotates, it drives the worm wheel 853 to rotate; the end of the worm 854 is installed with a hand wheel 855 for driving the worm 854 to rotate; the guide mechanism 856 is arranged on the sleeve 851, and the guide mechanism 856 includes a slider 8561 (as shown in the figure) arranged on the sleeve 851 Fig. 9 or Fig.11 As shown), the slider 8561 is slidably connected to the threaded rod 852 along the axial direction of the threaded rod 852 through the second vertical slide groove 8562; the linkage mechanism 857 includes a gear 8571; the two gears 8571 are coaxially arranged on the two worm gears 854 respectively; when the two mounting frames 71 are in the same plane, the two gears 8571 are meshed.

[0058] It should be noted that the worm 854 is driven to rotate by the hand wheel 855, thereby driving the worm wheel 853 to rotate, wherein the slider 8561 in the guide mechanism 856 cooperates with the second vertical slide groove 8562, so that the threaded rod 852 can only be lifted and lowered along the axis of the threaded rod 852. Therefore, the rotation of the worm wheel 853 can drive the threaded rod 852 to rise and fall, thereby driving the connecting rod 81 to rise and fall, so as to adjust the height of the rotating shaft 82 so that the rotating shaft 82 coincides with the axis of the cylindrical block 5; at this time, the axial self-locking characteristic of the worm 854 is used to realize the automatic locking of the rotating shaft 82 after the height adjustment, thereby improving the stability of use;

[0059] When the handwheel 855 drives one of the worm gears 854 to rotate, since the two steel plates 1 are in a horizontal splicing state at this time, the two mounting frames 71 are in the same plane, that is, the two gears 8571 are in a meshing state. Therefore, through the cooperation of the gear 8571, the other worm gear 854 can be driven to rotate, and then the two connecting rods 81 can be driven to rise and fall synchronously.

[0060] like Figure 6 and Figure 8-12 As shown, the lifting mechanism 85 also includes a supporting mechanism 858 for supporting the threaded rod 852; the supporting mechanism 858 includes a telescopic airbag 8581, a connecting pipe 8582, a one-way valve 8583 and a pressure relief mechanism 8584; the telescopic airbag 8581 is arranged on the mounting frame 71 (as shown in FIG. Figure 4 As shown), the top end of the telescopic airbag 8581 is connected to the threaded rod 852, one end of the connecting pipe 8582 is connected to the telescopic airbag 8581, and the one-way valve 8583 is arranged in the connecting pipe 8582; when negative pressure is generated in the telescopic airbag 8581, the one-way valve 8583 can be driven to open; the pressure relief mechanism 8584 is arranged at the other end of the connecting pipe 8582, and the pressure relief mechanism 8584 is used to drive the one-way valve 8583 to open.

[0061] It should be noted that when the height of the rotating shaft 82 needs to be adjusted, the rotating shaft 82 is first moved to the lowest position, and then the rotating shaft 82 is driven to rise until the rotating shaft 82 coincides with the axis of the cylindrical block 5. During the rising process of the rotating shaft 82, the telescopic airbag 8581 is pulled to expand, so that negative pressure is generated in the telescopic airbag 8581, and then the one-way valve 8583 is automatically opened. When the height adjustment of the rotating shaft 82 is completed, the one-way valve 8583 is closed, so that the telescopic airbag 8581 is sealed, and then when the threaded rod 852 generates downward pressure, that is, the steel plate 1 (such as Figure 1 As shown in the figure, the excessive gravity squeezes the threaded rod 852, and the threaded rod 852 squeezes the telescopic airbag 8581, and the telescopic airbag 8581 can provide an upward supporting force for the threaded rod 852 to relieve the pressure on the threaded teeth of the threaded rod 852 and prevent damage due to excessive pressure;

[0062] When it is necessary to drive the threaded rod 852 to move downward, the one-way valve 8583 is maintained in an open state through the pressure relief mechanism 8584, so that the telescopic airbag 8581 is connected to the outside through the connecting pipe 8582, without affecting the normal descent of the threaded rod 852.

[0063] like Figure 9-12 As shown, the pressure relief mechanism 8584 includes a mounting block 85841, a connecting shaft 85842, a stopper 85843 and a ball 85844; the mounting block 85841 is arranged on the connecting tube 8582, one end of the connecting shaft 85842 is plugged into the connecting tube 8582, and the connecting shaft 85842 is threadedly connected to the mounting block 85841, the stopper 85843 is arranged in the connecting tube 8582, and a plurality of ball 85844 is arranged in the connecting tube 8582. The diameter of 85844 is smaller than the inner diameter of the connecting pipe 8582; when the one-way valve 8583 is closed, the ball 85844 closest to the one-way valve 8583 collides with the top ball of the one-way valve 8583, and one end of the connecting shaft 85842 passes through the stopper 85843 and approaches the ball 85844 farthest from the one-way valve 8583; under the action of gravity, adjacent ball bearings 85844 collide with each other; through holes are provided on the mounting block 85841 and the stopper 85843.

[0064] It should be noted that when the one-way valve 8583 needs to be opened, the connecting shaft 85842 is first rotated to make the connecting shaft 85842 move downward to squeeze the ball 85844, and the pressure is transmitted through multiple balls 85844 to squeeze the top ball of the one-way valve 8583, so that the one-way valve 8583 is opened, and the telescopic airbag 8581 is connected to the outside world through the connecting tube 8582, thereby achieving the purpose of pressure relief.

[0065] like Figure 9-12 As shown, the support mechanism 858 also includes a display shaft 82 (such as Figure 6 The position display mechanism 8585 for indicating the height of the axis of the rotating shaft 82 is shown in the figure; the position display mechanism 8585 includes a piston 85851 and a scale 85852; the piston 85851 is coaxially slidably connected to the connecting shaft 85842; the connecting pipe 8582 includes an arc section and a vertical section, the arc section is connected to the telescopic airbag 8581, and the vertical section is connected to the arc section, the vertical section is a transparent structure, and the scale 85852 is arranged on the transparent structure of the vertical section; the interior of the telescopic airbag 8581 and the connecting pipe 8582 between the telescopic airbag 8581 and the piston 85851 are filled with oil; the height of the axis of the rotating shaft 82 can be indirectly reflected by observing the position of the scale 85852 corresponding to the height of the oil.

[0066] It should be noted that when the driving shaft 82 moves to the lowest end, the telescopic airbag 8581 is squeezed, so that the oil rises to the top scale 85852 position of the connecting pipe 8582, and the distance from the protrusion 4 to the steel plate 1 (such as Figure 1 The vertical distance on one side of the shaft 82 is calculated by the distance to calculate the height H that the shaft 82 needs to rise; then the threaded rod 852 is driven to rise until the shaft 82 coincides with the axis of the cylindrical block 5; during the rising process of the threaded rod 852, the telescopic airbag 8581 continuously expands, absorbs the oil in the connecting pipe 8582, causing the oil in the connecting pipe 8582 to drop, and when the data of the scale 85852 corresponding to the top of the oil is observed to be H, it is determined that the shaft 82 coincides with the axis of the cylindrical block 5; that is, the setting of the position display mechanism 8585 improves the convenience and accuracy of adjustment.
