[0033] Common lifting construction devices are scissor-type, mast-type, sleeve cylinder-type lifting vehicles, etc. The application scenarios of such equipment are generally suitable for situations where they are in contact with the ground. For high-altitude operations such as storage tanks, such equipment is difficult to function when the equipment is not in contact with the ground. When the height of the plate is high, the difficulty and risk factor of construction workers working at high altitudes are greater. Therefore, there is currently no equipment used in the work scene of tank weld welding.

[0034] Figure 1 to Figure 2An embodiment of a construction device 10 according to the utility model is shown. The utility model provides a construction device 10, which is used for welding the welds to be welded of a storage tank 20, and the storage tank 20 includes a wall panel 21. The construction device 10 includes a moving mechanism 100 and a lifting mechanism 200 for hanging on the wall panel 21, the moving mechanism 100 can move along the top of the wall panel 21, the lifting mechanism 200 is connected to the moving mechanism 100, and the lifting mechanism 200 can move up and down along the wall panel 21. The moving mechanism 100 is provided with a welding structure 300 for welding the welds to be welded on both sides of the wall panel 21. The lifting mechanism 200 includes a lifting platform 210 for construction workers to ride on and a lifting guide rail 220, the lifting guide rail 220 and the lower end of the moving mechanism 100 are detachably connected, and the lifting platform 210 can move along the lifting guide rail 220 so that the construction workers can ride the lifting platform 210 to rise and fall. The lifting platform 210 is connected to the moving mechanism 100 so that construction workers can climb between the lifting platform 210 and the moving mechanism 100. The lower end of the moving mechanism 100 has an adjustment structure 112a, and the upper end of the lifting guide rail 220 has an adjustment matching structure 221. The adjustment structure 112a and the adjustment matching structure 221 are connected and matched to adjust the height of the lifting guide rail 220 from the ground to adapt to wall panels 21 of different widths.

[0035] The construction device 10 provided by the utility model can be applied to the vertical welding seams of the tank wall panels 21. The welding structure 300 can realize the welding operation of the tank 20 weld seams. The device can be driven as a whole to move along the wall panels 21 through the suspended motion mechanism 100 to realize the overall construction operation of the tank 20. The adjusting structure 112a and the adjusting matching mechanism 221 connected and matched with the adjusting structure 112a can adapt to wall panels 21 of different heights. Construction personnel can take the lifting mechanism 200 located on both sides of the tank wall panels 21 to complete the welding and grinding operations of the inner and outer welds of the wall panels 21 with a certain height. The lifting mechanism 200 can be automatically lifted and lowered by construction personnel. When the height of the plate is high, the difficulty of construction personnel in constructing the vertical seams of the plate splicing can be reduced, and the construction efficiency can be improved. It is suitable for complex industrial production environments and provides protection for the safety of construction personnel.

[0036] Figure 2 The working scene of an embodiment of the construction device 10 provided by the utility model is shown. The storage tank 20 is enclosed by the wall panel 21 and has a certain volume. The wall panel 21 divides the storage tank 20 into a tank interior 23 and a tank exterior 22. The side of the wall panel 21 facing the tank interior 23 is the inner side of the wall panel 21, and the side of the wall panel 21 facing the tank exterior 22 is the inner side of the wall panel 21. Figure 2 and Fig.13As shown. Since both the inner and outer welds of the wall panel 21 need to be welded, there are two lifting mechanisms 200, and the construction personnel can take the lifting mechanism to lift along the inner or outer side of the wall panel 21. There are two lifting mechanisms 200, and the two lifting mechanisms 200 are opposite to each other and are respectively connected to the motion mechanism 100. The two lifting mechanisms 200 can be respectively located on the opposite sides of the wall panel 21, so that the lifting mechanisms 200 are used to carry the construction personnel to perform welding construction operations on both sides of the wall panel 21. In the working state, the motion mechanism 100 is suspended at the top of the wall panel 21, and the two lifting mechanisms 200 are respectively located on the inner and outer sides of the wall panel 21. The construction device 10 can be arranged in a mirror image on the inner and outer sides of the wall panel 21, that is, the lifting mechanism 200 outside the tank 22 and the lifting mechanism 200 inside the tank 23 are opposite to each other, and part of the motion mechanism 100 outside the tank 22 and part of the motion mechanism 100 inside the tank 23 are opposite to each other.

[0037] Figures 3 to 5 The construction device 10 is shown in different viewing angles. In one embodiment, the motion mechanism 100 includes a frame structure 110 and a driving structure 120 connected to the frame structure 110. The driving structure 120 is used to drive the frame structure 110 to move along the top of the wall panel 21. The frame structure 110 can be a steel structure with high strength and can bear a certain weight of the equipment.

[0038] In one embodiment, the driving structure 120 includes at least two driving wheel sets 121 arranged side by side and spaced apart from each other, which can ensure the stability and balance of the motion mechanism 100 during movement. Figure 4 As shown, the driving wheel set 121 of one embodiment of the utility model is two, which are respectively arranged at Figure 4 The left and right sides of the frame structure 110 on the upper part can better balance the motion mechanism 100. Of course, more driving wheel groups 121 can be set to further enhance the motion stability. The number of motors used to drive the driving wheel groups 121 can be selected according to the number of driving wheel groups 121. The motor can be installed on the frame structure 110, and its installation position is determined by the degree of space utilization.

[0039] refer to Fig.11 and Fig.12 The schematic diagram of the driving wheel set 121 shown in the figure, the driving wheel set 121 includes a driving wheel 121a detachably connected to the frame structure 110 and side guards 121b arranged on both sides of the driving wheel 121a. The driving wheel 121a is connected to the frame structure 110 through a connecting member 121c. The connection method of the connecting member 121c and the frame structure 110 can be a threaded connection, which is convenient for changing the position of the driving wheel set 121 on the frame structure 110. Figures 2 to 5As shown, the frame structure 110 includes a climbing platform 111a-3 located above the wall panel 21, and the driving wheel set 121 is connected to the bottom of the climbing platform 111a-3. Furthermore, the gap between the connecting plates on both sides of the connecting member 121c is consistent with the thickness of the side plate of the climbing platform 111a-3, so that the connecting member 121c can be assembled on the side plate of the climbing platform 111a-3 to achieve a relatively stable connection.

[0040] like Figure 3 As shown, the wall plate 21 facing the inside 23 of the tank, that is, the inner side of the wall plate 21 is usually not a simple plate, but has a protruding portion inside, such as Figure 3 The protruding parts of the wall panels 21 on the left, bottom and middle positions. Therefore, in order to avoid interference with the protruding parts of the wall panels 21 on the inner side of the storage tank 20, the installation position of the driving wheel set 121 needs to avoid the protruding parts. The detachable design of the driving wheel set 121 facilitates flexible adjustment of the installation position according to the protruding parts. Figure 3 , the driving wheel set 121 can be Figure 3 Adjust the position in the left and right directions, not limited to Figure 3 On the axis of the motion mechanism 100.

[0041] Since the multiple driving wheel groups 121 can be arranged asymmetrically about the axis of the motion mechanism 100, the weight distribution of the motion mechanism 100 on both sides of the axis of the driving wheel 121a (i.e., the wall panel 21) will also be different. The side guard 121b of the driving wheel group 121 is closely attached to the side of the driving wheel 121a, and the side guard 121b is used to limit the moving direction of the driving wheel 121a. The driving wheel 121a is restricted and can only move at the top of the wall panel 21, which can reduce the risk of the driving wheel 121a tipping over to the side due to uneven weight distribution on both sides, or even the risk of the entire construction device 10 tilting, avoiding scratches between the device and the wall panel 21, and ensuring the safety of the construction operation.

[0042] In order to further reduce the risk of the device tilting and ensure operational stability, in one embodiment, the construction device 10 also includes at least one push rod group 400, the push rod group 400 includes a first push rod 410 and a second push rod 420 opposite to the first push rod 410, the first push rod 410 and the second push rod 420 are respectively arranged on two lifting mechanisms 200 located on both sides of the wall panel 21, the first push rod 410 and the second push rod 420 are used to respectively resist the wall panel 21 to apply pressure to the wall panel 21, and the reverse force generated by the pressure makes the moving mechanism 100 and the lifting mechanism 200 remain vertical to prevent the construction device 10 from tilting.

[0043] like Figure 3As shown in FIG. 6 , the push rod group 400 can be arranged at the bottom of the lifting mechanism 200, and the driving wheel group 121 is close to the top of the device. The push rod group 400 and the side guard 121b of the driving wheel group 121 work together to keep the device in a vertical state. The number of the push rod group 400 can be one group, or two groups or more. As shown in the top view of the construction device 10 of FIG. 6 , the two push rod groups 400 are respectively arranged at Figure 6 The upper and lower sides of the device are the opposite sides of the device in the Y direction, so that the vertical state of the construction device 10 as a whole can be better guaranteed. The ends of the first push rod 410 and the second push rod 420 are support wheels, and the two support wheels can jointly support the wall plate 21. The first push rod 410 and the second push rod 420 can be hand-cranked push rods.

[0044] like Figure 6 As shown, the first push rod 410 on the left is located inside the tank 23, and the second push rod 420 on the right is located outside the tank 22. The pressure exerted on the wall plate 21 by the support wheels of the first push rod 410 and the second push rod 420 can be controlled according to the different weight distribution on both sides.

[0045] In one embodiment, the upper end of the driving wheel 121a is connected to a bearing so that the driving wheel 121a can rotate in the vertical direction, thereby enabling the driving wheel 121a to move along the extension direction of the wall panel 21 and in close contact with the top of the wall panel 21. Since the storage tank 20 welded by a plurality of wall panels 21 is cylindrical in shape as a whole, and the wall panel 21 has a certain curvature, the self-rotating driving wheel 121a can reduce the walking resistance caused by the friction between the side ribs and the wall panel 21, while avoiding damage to the wall panel 21 and the side ribs 121b. The rotation limit of the driving wheel 121a can be determined according to the size of the device and the diameter of the wall panel 21.

[0046] refer to Fig. 9 In one embodiment, the lifting mechanism 200 includes a lifting platform 210 and a lifting guide rail 220 connected to the lower end of the frame structure 110, and the lifting platform 210 can move along the lifting guide rail 220. The lifting mechanism 200 also includes a lifting drive unit 230. Figures 2 to 5 As shown, the lifting drive unit 230 is arranged at the top of the lifting guide rail 220 and is located on the side of the lifting guide rail 220 to avoid interfering with the lifting platform 210. The lifting platform 210 moves up and down under the guidance of the lifting guide rail 220 through the guide wheel. The lifting drive unit 230 can be selected as a driving motor, and the driving motor drives the sprocket to lift and lower, so that lifting can be achieved without contacting the ground. The lifting guide rail 220 can be selected as a steel structure.

[0047] In the related art, a winch is used as a power mechanism, which is prone to shaking, and shaking is strictly prohibited during welding; and its lifting height is limited by the length of the wire rope. The construction device 10 of the utility model adopts chain transmission, which is more stable, can cover the entire length of the weld, and has higher applicability.

[0048] The lifting platform 210 is provided with a railing to ensure the safety of construction workers working at height. The frame structure 110 and the two lifting platforms 210 are connected so that construction workers can move between the lifting platforms 210 and the frame structure 110. Figure 6 The construction workers' climbing route shown by the dotted line is that the construction workers can take the lifting platform 210 inside the tank 23 or outside the tank 22 to the highest point, climb from the lifting platform 210 to the upper part of the frame structure 110, that is, the climbing platform 111a-3, and then enter the lifting platform 210 on the other side to complete the climbing of the tank wall panel 21. A guardrail 114 is set on the top of the frame structure 110 to prevent accidents when climbing or repairing. The guardrail 114 can be foldable and detachable. The guardrail 114 can only cover the storage part 111, such as Figure 8 It can also cover the storage portion 111 and the non-storage portion 112, such as Figures 2 to 5 shown.

[0049] like Figures 1 to 6 As shown, the frame structure 110 is assembled from a plurality of columnar parts, and is easy to disassemble and assemble. The mesh part can also be further assembled on the side of the frame structure 110, such as Figure 2 and Figure 4 To prevent people or objects from falling.

[0050] In one embodiment, the frame structure 110 has a storage part 111 and a non-storage part 112 arranged side by side. The storage part 111 is used to place work items 30, including but not limited to a power distribution cabinet, a vacuum pump, and a gas control cabinet. The non-storage part 112 is provided with an adjustment structure 112a, and the welding structure 300 is provided in the non-storage part 112. The non-storage part 112 cannot place work items 30 and other items, but can be equipped with a welding track 320 with a welding structure 300, a module, a hoisting equipment, etc. as needed for transporting materials and engaging in construction production.

[0051] refer to Figure 4 and Figure 5In one embodiment, the storage portion 111 includes an upper storage area 111a and a personnel operation area 111b that can accommodate construction personnel. The upper storage area 111a is provided with a plurality of storage platforms 111a-1 for placing the work items 30 such as power distribution cabinets, vacuum pumps, and gas control cabinets mentioned above. The storage platform 111a-1 can be optionally designed as a push-pull drawer to facilitate the placement of work items 30. Specifically, the upper storage area 111a located on the climbing platform 111a-3 can be fixed with a power distribution cabinet, a vacuum pump, and a gas control cabinet. The upper storage area 111a located under the climbing platform 111a-3 can be used to place items including but not limited to automatic welding wire feeders, manual welding wire feeders, automatic welding power supplies, manual arc welding power supplies, control cabinets, etc. according to the needs of construction personnel. Reference Figure 7 There are two personnel operation areas 111b, which are respectively connected to the upper storage areas 111a and the lifting guide rails 220 located on both sides of the wall panel 21.

[0052] The personnel operation area 111b is connected to the upper storage area 111a and the lifting rail 220. The upper storage area 111a and the non-storage part 112 are a frame as a whole. The lifting mechanism 200 connected in pairs, the upper storage area 111a and the non-storage part form a frame as a whole, and the personnel operation area 111b can make the device as a whole more stable, less prone to shaking, reduce the impact on the welding effect, and make the device more integrated and complete.

[0053] The personnel operation area 111b is connected to the lifting platform 210 so that construction personnel can move between the personnel operation area 111b and the lifting platform 210.

The operation panel 111b-1 can be a touch screen.

[0054] The activity route of the construction workers can be as follows: the construction workers control the welding and other construction processes through the operation panel 111b-1 on the personnel operation platform 111b-3. Then, they can enter the lifting platform 210 from the personnel operation platform 111b-3, and the lifting platform 210 drives the construction workers to move up and down to grind the weld or other construction operations, and then climb over the climbing platform 111a-3 to the other side to repeat the above construction operations. If construction control is required, the construction workers can control the lifting platform 210 to descend to the personnel operation platform 111b-3 through the hand control box and operate on the operation panel 111b-1.

[0055] In one embodiment, the upper end of the personnel operation area 111b has a first adjustment portion 111b-2, and the lower end of the upper storage area 111a has a first adjustment matching portion 111a-2. The first adjustment portion 111b-2 and the first adjustment matching portion 111a-2 are connected and matched to adjust the height of the personnel operation area 111b from the ground. The frame structure 110 also includes a sleeve 113, the sleeve 113 has a plurality of adjustment holes 113a arranged at intervals, the first adjustment portion 111b-2 is a plurality of first installation holes 111b-21 arranged at intervals, and the first adjustment matching portion 111a-2 is a plurality of first installation matching holes 111a-21 arranged at intervals.

The first mounting hole 111b-21, the first mounting matching hole 111a-21 and the adjustment hole 113a can be arranged at equal intervals.

[0056] The sleeve 113 can be adjusted according to the length requirements to adapt to various plate widths. The overall height of the device can be adjusted within a certain range according to the plate width to be welded. In addition, the deformation problem of the connecting portion 111b-4 (i.e., the sleeve 113) can be solved more conveniently by replacing the sleeve 113. Figure 8 and Fig.10 As shown, the number of sleeves 113 is determined according to the overall layout of the frame structure 110, such as Fig.10 As shown, there are four sleeves 113. The number and interval of the adjustment holes 113a provided on the sleeves 113 and the length of the sleeves 113 can be determined according to the width of the wall panel 21 and the height range to be adjusted.

[0057] In one embodiment, the upper end of the lifting guide rail 220 has an adjustment matching structure 221, and the lower end of the non-storage part 112 is provided with an adjustment structure 112a. The first adjustment portion 111b-2 and the first adjustment matching portion 111a-2 are connected and matched to adjust the height of the lifting guide rail 220 from the ground. Through the extension portion of the lifting guide rail 220, it is connected to the non-storage part 112 by inserting different pin positions, so as to adapt to different frame heights. The extension portion can be selected as an angle steel. The specific connection form is that the lifting guide rail 220 is welded with an angle steel to prevent the track from deforming and for connection, and equidistant openings are opened at the lower ends of the angle steel and the non-storage part 112 in turn. When the overall height of the equipment needs to be adjusted, the above-mentioned openings can be reconnected with fasteners.

[0058] In order to ensure the connection effect of the lifting mechanism 200, the bottom of the personnel operation area 111b is provided with an extended connection part 111b-4 for connecting with the lifting guide rail 220. The bottom of the connection part 111b-4 is provided with a support part 111b-5, which has a certain function of supporting the lifting guide rail 220 of the steel structure. A plurality of connection holes 111b-41 are provided at the top of the connection part 111b-4. The connection holes 111b-41 can be threaded holes. A plurality of through holes are provided at the bottom of the lifting guide rail 220. After the height adjustment of the personnel operation area 111b and the lifting guide rail 220 is completed, the connection part 111b-4 and the lifting guide rail 220 are locked by fasteners to complete the overall assembly of the device.

[0059] Through the cooperation between the first adjustment part 111b-2, the first adjustment matching part 111a-2, the sleeve 113, and the cooperation between the adjustment matching structure 221 and the adjustment structure 112a, the height of the device as a whole from the ground is adjustable, increasing the flexibility of the height adjustment of the device. Taking a storage tank with a height of 40m as an example, the welded plate width is 3325mm in height. Considering that the inner side of the wall panel 21 has a protruding part, in order to avoid the protruding part (especially the bottom wall panel 21), the height from the bottom of the driving wheel 121a to the bottom of the device as a whole (i.e., the bottom of the personnel operation area 111b) needs to be changed to within 3325m. It can be adjusted by the above-mentioned adjustment method, which will not be repeated.

[0060] Figure 8 A portion of the motion mechanism 100 is shown. In one embodiment, reference Figure 8 The construction device 10 also includes a climbing structure for construction workers to climb, and the climbing structure includes a plurality of footrests 510, which are arranged at intervals on the side of the motion mechanism 100 close to the lifting mechanism 200. The plurality of footrests 510 can be arranged in the upper storage area 111a of the motion mechanism 100, and face the lifting guide rail 220. In an emergency such as a sudden power outage, the construction workers can safely descend to the platform through the folding footrests 510 in the storage area. The footrests 510 can be selected as folding footrests 510, which can be folded and stored in non-emergency situations to avoid affecting the operation of the construction workers on the lifting platform 210.

[0061] refer to Figure 6In one embodiment, the welding structure 300 includes a welding track 320 and a welding carriage 310 for welding. The welding carriage 310 can move along the wall panel 21 under the guidance of the welding track 320. The welding structure 300 also includes a hanging plate 330 and a driving module 340 for driving the hanging plate 330 to move. The driving module 340 is arranged on the frame structure 110. The welding track 320 is detachably connected to the hanging plate 330. The hanging plate 330 is used to adjust the height of the welding track 320 from the ground. There are several holes on the hanging plate 330 to facilitate the adjustment and fixing of the height of the welding track 320. The driving module 340 includes an electric push rod 341, a first track 342 and a second track 343. The electric push rod 341 pushes the second track 343 to move on the first track 342, and the hanging plate 330 can move on the second track 343. In this way, the driving module 340 can drive the hanging plate 330 to move. Figure 6 The welding track 320 can be moved in the X and Y directions. Accordingly, the welding track 320 can be flexibly moved in three axes, which is convenient for adjusting the welding position and direction. The automatic welding head of the welding trolley 310 can be equipped with a camera. The welding track 320 and the automatic welding head suspended in the non-placement area are not blocked by obstacles, ensuring the welding effect.

[0062] refer to Figure 4 and Figure 5 The non-storage part 112 and the upper storage area 111a, the lifting mechanism 200 and the personnel operation area 111b located below the climbing platform 111a-3 are mirrored on both sides of the wall panel 21, and the setting of the welding track 320 and the operation panel 111b-1, and the placement of the work items 30 in the storage part 111 are also mirrored on both sides of the wall panel 21.

[0063] Since both the front and back sides of the thick-walled plate 21 need to be welded, in order to improve efficiency, two sets of construction devices 10 can be designed according to the embodiment of the utility model, that is, one set of devices is used for back side welding (i.e., inside the tank 23), and the other set is used for front side welding (i.e., outside the tank 22). The welding track 320 of the construction device 10 for back side welding can be set inside the tank 23, i.e. Figure 6 The welding track 320 of the construction device 10 for front welding can be arranged outside the tank 22, that is, Figure 6 The right side of the wall panel 21 in the middle. After the back device completes the back of this weld, the device can move to another weld to weld the back of the next weld, and then the device for welding the front side welds the completed weld on the back, which can improve the welding efficiency. The welding track 320 is heavy and long, and it is difficult to change the position at a high place. By using two sets of devices running simultaneously, it is possible to avoid changing the position of the welding track 320 back and forth. The specific structures of the two sets of devices can be set according to actual conditions, and are not limited to being completely the same or mirrored.

[0064] The construction device 10 provided by the utility model can be used in the vertical seam welding operation of the LNG storage tank wall plate 21. The following is the assembly process of the construction device 10 of the utility model:

[0065] First, determine the wall panel 21, that is, the width of the plate to be welded, and change the overall height of the device. Specifically: Lay the device down, pull out the fasteners between the lower part of the sleeve 113 and the personnel operation area 111b, and then remove the bolts used to connect the connecting part 111b-4 of the personnel operation area and the bottom of the lifting guide rail 220, and adjust the personnel operation area 111b to a suitable height. Install the fasteners between the upper storage area 111a and the personnel operation area 111b. Take out the fasteners between the lifting guide rail 220 and the non-storage part 112 of the frame structure 110, use a crane or other lifting equipment to adjust the lifting guide rail 220 to a suitable installation position, and then fix the fasteners between the lifting guide rail 220 and the non-storage part 112, and between the lifting guide rail 220 and the personnel operation area 111b.

[0066] The welding rail 320 is fixed at a suitable position of the hanging plate 330 by using a hoisting device.

[0067] Then, the entire device is hoisted onto the wall panel 21 .

[0068] Finally, the support wheel of the push rod is pushed against the wall plate 21 to make the whole device vertical.

[0069] The following are the operating steps for construction personnel to use the construction device 10 of the utility model:

[0070] The personnel operation area structure allows the operator to operate on the display screen. After welding is completed, the operator can take the lifting mechanism 200 platform to grind the weld.

[0071] When welding the inside 23 or the outside 22 of the tank, the construction personnel directly enter the personnel operation area 111b to weld the weld to be welded.

[0072] After the welding of one side of the wall panel 21 is completed, the construction personnel can take the lifting platform 210 to grind the weld. Figure 6 As indicated by the dotted arrow in the middle, the construction workers ascend the lifting platform 210 inside the tank 23 or outside the tank 22 to the top of the lifting mechanism 200, then wear a safety belt and climb over to the climbing platform 111a-3 in the upper storage area 111a, then climb over from the climbing platform 111a-3 to the lifting platform 210 on the other side, and descend the lifting platform 210 to the bottom to observe the control panel for welding.

[0073] The operator can use the lifting platform 210 to rise to the upper control area (over the platform 111a-3) to perform maintenance operations on the electrical control.

[0074] In an emergency such as a sudden power outage, the construction workers can safely descend to the lifting platform 210 or the personnel operating platform 111b-3 by using the foot pedal 510.

[0075] The construction device 10 of the utility model has both electric lifting and personnel climbing functions. When the height of the plate is high, it can solve the problems of construction personnel climbing, climbing over the plate or difficulty in constructing the vertical seam of the plate splicing. At the same time, the device has an adjustment function, which can adjust its own height to meet the preparation requirements of welding conditions and expand the application occasions. Under normal circumstances, construction personnel can take the lifting platform 210 to complete welding and grinding operations of welds with a certain height. If the lifting mechanism 200 fails, an accident occurs, or there is a special need, a solution for autonomous climbing is provided for construction personnel, which is more suitable for complex industrial production environments and provides double protection for the safety of construction personnel. In addition, the device carries welding equipment and the like during the movement, and is convenient for welding on one side and using the lifting platform on the other side to flush the protective gas on the back of the weld, etc. A series of coordinated work. Moreover, after the welding process is completed, the construction personnel can also take the lifting platform to grind the entire weld.
