Description

Technical Field

[0001] The invention belongs to the technical field of oil storage tank reinforcement, and in particular relates to an oil storage tank wall reinforcement device and a reinforcement method thereof. Background Art

[0002] At present, in order to ensure the storage demand of edible oil in my country, large oil storage tanks are being actively built. Most of the existing oil storage tanks are made of metal. As the years of use increase, there are cases where the tank wall of the oil storage tank is irreversibly deformed due to external factors. Based on this, a method for reinforcing the tank wall of the oil storage tank is proposed to address this situation.

[0003] For example, the invention patent with patent application publication number: CN114346506A, which involves a method for reinforcing the tank wall approach bridge of an oil storage tank, includes the following specific steps: Step 1, using steel plates to prepare reinforcement plates that meet the strength requirements of the oil storage tank according to the specifications of the oil storage tank; Step 2, injecting water into the oil storage tank to raise the floating boat to the tank wall reinforcement position for construction; Step 3, welding the reinforcement plate along the edge to the inner side of the tank wall of the corrosion pit to form an annular reinforcement plate; Step 4, welding a sloped approach bridge on the upper and lower edges of the annular reinforcement plate.

[0004] Based on the search of patent application publication numbers and the shortcomings found therein:

[0005] The existing methods of reinforcing the tank wall of oil storage tanks are all achieved through manual welding.

DETAILED DESCRIPTION

[0035] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0036] See also Figure 1-5The present embodiment provides an oil tank wall reinforcement device, including a moving component, a welding component 2, a positioning component 3 and a pressing component 4. The moving component includes a moving shell 1, and the moving shell 1 can be slidably arranged on the wall of the oil tank. The positioning component 3 includes a positioning mechanical claw, which is mounted on the moving shell 1 and is used to locate the position of the reinforcement plate; the pressing component 4 includes a pressing mechanical claw, which is mounted on the moving shell 1 and is used to press the reinforcement plate to fit the wall of the oil tank. The welding component 2 includes a welding device and a welding mechanical claw, and the output end of the welding device is mounted on the welding mechanical claw. The welding device and the welding mechanical claw are both mounted on the moving shell 1 and are used to position the reinforcement plate that has been positioned. The plate is welded to the wall of the oil tank; this solution is provided with a mobile shell 1, which can slide on the wall of the oil tank, thereby driving the welding assembly 2, the positioning assembly 3 and the pressing assembly 4 mounted on the mobile shell 1 to move together on the wall of the oil tank, and through the cooperation of the welding assembly 2, the positioning assembly 3 and the pressing assembly 4, the reinforcement plate is welded to the position to be reinforced on the wall of the oil tank, which solves the problem that the existing method of reinforcing the wall of the oil tank is achieved by manual welding. Since the height of the oil tank for storing edible oil generally reaches 30m, if the position where the oil tank is deformed is at the top of the oil tank, it means that it is necessary to manually climb to the top of the oil tank to work. This not only increases the safety risk of the operators, but also leads to unstable welding quality due to the limited working environment, thereby affecting the overall structural strength and sealing of the oil tank.

[0037] Specifically, in order to realize the structural effect of the mobile shell 1 of the present scheme having the mobility, the mobile assembly of the present scheme also includes two mobile units 5, and the two mobile units 5 are symmetrically arranged on the left and right sides of the bottom of the mobile shell 1 respectively; the mobile unit 5 includes a frame 501, a crawler 502, a plurality of rotating wheels 503 and a rotating motor 504, the frame 501 is fixedly arranged at the bottom of the mobile shell 1, and the plurality of rotating wheels 503 are arranged on the frame 501 at equal intervals along the axial direction of the frame 501, the rotating motor 504 is coaxially connected to any rotating wheel 503, and the crawler 502 is rotatably mounted on the outer ring formed by the plurality of rotating wheels 503; through such an arrangement, when the rotating motor 504 starts to rotate, the rotating motor 504 drives the rotating wheel 503 to rotate, thereby driving the crawler 502 mounted on the rotating wheel 503 to rotate, and finally the rotation of the crawler 502 drives the entire rotating wheel 503 to rotate together, so as to realize the movement of the mobile shell 1. It is worth noting that when the output speeds of the two rotating motors 504 are the same, the moving housing 1 moves in a straight line; when the output speeds of the two rotating motors 504 are different, the moving housing 1 will rotate leftward or rightward to realize the rotation of the moving housing 1.

[0038] In addition, since the mobile shell 1 of the present solution moves on the tank wall of the oil storage tank, the mobile shell 1 is also required to have a structural effect of being adsorbed on the tank wall of the oil storage tank. Based on this, the mobile assembly of the present solution also includes two adsorption units 6, and the two adsorption units 6 are respectively arranged at the front and rear ends of the bottom of the mobile shell 1; the adsorption unit 6 includes two fixed plates 601, a sliding plate 602, a plurality of suction nozzles 603 and an air pump 604, and the two fixed plates 601 are respectively arranged on both sides of one end of the mobile shell 1, and the fixed plate 601 is provided with a sliding groove, and the sliding plate 604 is provided with a plurality of suction nozzles 603 and an air pump 604. 02 is slidably arranged between two fixed plates 601 along the setting direction of the sliding groove, and a plurality of suction nozzles 603 are arranged on the sliding plate 602 at equal intervals along the axial direction of the sliding plate 602. The plurality of suction nozzles 603 are connected to the air pump 604 through an air pipe, and the air pump 604 is arranged at the bottom of the mobile shell 1; by providing an adsorption unit 6, when the air pump 604 starts to work, negative pressure will be generated in the suction nozzle 603, and the suction nozzle 603 will be adsorbed on the tank wall of the oil storage tank, thereby realizing the structural effect that the mobile shell 1 can move along the tank wall of the oil storage tank. It should be noted that, since the movable shell 1 relies on the suction nozzle 603 to be adsorbed on the wall of the oil storage tank, in order to ensure the adsorption capacity of the suction nozzle 603, it is necessary to ensure that the suction nozzle 603 cannot move when it is adsorbed on the wall of the oil storage tank; therefore, when the movable shell 1 moves, it is necessary to ensure that the suction nozzle 603 cannot move; based on this, the present scheme is provided with a fixed plate 601, on which a sliding groove is provided, when the suction nozzle 603 is adsorbed on the wall of the oil storage tank, the sliding plate 602 cannot move, and when the movable shell 1 moves, the movable shell 1 will move relative to the sliding plate 602 and the suction nozzle 603 provided on the sliding plate 602 due to the structure of the sliding groove; it is also worth noting that at this time the movable shell 1 can only move along the setting direction of the sliding groove, that is, it can only move straight and cannot rotate.

[0039] According to the description of the above embodiment, since the length of the sliding groove is limited, after the sliding plate 602 cooperates with the end of the sliding groove, the sliding plate 602 needs to be moved back to the front end of the sliding groove to ensure the structural effect that the suction nozzle 603 cannot move when the movable shell 1 moves; based on this, the adsorption unit 6 of this scheme also includes a reset spring 605 and a control module 606, the two ends of the reset spring 605 are respectively connected to the sliding plate 602 and one end of the fixed plate 601, and the control module 606 is arranged at the end of the sliding plate 602 away from the initial position of the sliding groove, that is, the control module 606 is arranged at the end of the sliding groove, and the control module 606 is connected to the air pump 604 for communication, and the control module 606 can lock or release the pressing fit relationship between it and the sliding plate 602; by providing the control module 606 and the return spring 605, when the sliding plate 602 moves to the end of the sliding groove, the sliding plate 602 realizes the pressing fit relationship of the control module 606. Since the control module 606 is connected to the air pump 604 for communication, when the control module 606 is pressed, the control module 606 will control the air pump 604 to stop working, so that the suction nozzle 603 is no longer adsorbed on the wall of the oil storage tank, and then the sliding plate 602 is reset to the front end of the sliding groove due to the action of the return spring 605.

[0040] Furthermore, the adsorption unit 6 of the present scheme also includes a plurality of lifting springs 607, and the sliding plate 602 is provided with a plurality of matching holes, and the plurality of matching holes are matched one-to-one with the plurality of suction nozzles 603, and any suction nozzle 603 can be lifted and lowered in the corresponding matching holes, and the plurality of lifting springs 607 are matched one-to-one with the plurality of suction nozzles 603, and any lifting spring 607 is sleeved in the corresponding matching holes, and the two ends of the lifting spring 607 are respectively connected to the sliding plate 602 and the corresponding suction nozzle 603, and by providing the lifting spring 607, due to the action force of the lifting spring 607, the suction nozzle 603 will always stick to the wall of the oil storage tank, thereby ensuring the normal operation of the device.

[0041] According to the above embodiment, since the suction nozzle 603 is always in contact with the wall of the oil storage tank, when the sliding plate 602 moves to the end of the sliding groove and presses the control module 606, the air pump 604 stops working, and then due to the force of the return spring 605, the sliding plate 602 is pushed to move toward the front end of the sliding groove. However, after the sliding plate 602 releases its pressing and matching relationship with the control module 606, the air pump 604 restarts working, so that the sliding plate 602 has not yet reached the front end of the sliding groove. In order to solve this problem, the adsorption unit 6 of the present invention further includes a lifting block 608 and a lifting spring 609. The fixing plate 601 further includes an annular groove 6011. The bottom end of the annular groove 6011 is overlapped and communicated with the sliding groove. A lifting slot hole is dug at one end of the bottom of the annular groove 6011 close to the control module 606. The lifting slot hole is communicated with the annular groove 6011. The lifting block 608 is lifted and lowered in the lifting slot hole. The two ends of the lifting spring 609 are connected to the lifting block 608 and the lifting slot hole respectively, and the sliding plate 602 can lock or release the abutting relationship between it and the lifting block 608; through such a setting, as the sliding plate 602 gradually moves toward the end of the sliding slot, the sliding plate 602 will press the lifting block 608, so that the lifting block 608 shrinks into the lifting slot hole; when the sliding plate 602 presses the control module 606, the suction nozzle 603 is no longer adsorbed on the wall of the oil storage tank, and at the same time, the lifting block 60 8 Due to the force of the lifting spring 609, the sliding plate 602 will be lifted to the top of the annular groove 6011, and then the sliding plate 602 will move toward the top front end of the annular groove 6011 due to the force of the return spring 605, until the sliding plate 602 moves to the top front end of the annular groove 6011, and then due to the force of the return spring 605, the sliding plate 602 will fall along the top front end of the annular groove 6011 to the bottom front end of the annular groove 6011, thereby realizing the reset of the sliding plate 602. It is worth noting that such a setting requires that the elastic modulus of the lifting spring 609 is greater than the elastic modulus of the return spring 605; in addition, when the sliding plate 602 is located at the top of the annular groove 6011, the suction nozzle 603 releases its fitting relationship with the wall of the oil storage tank. Even if the air pump 604 starts working again, the suction nozzle 603 cannot be adsorbed on the wall of the oil storage tank until the sliding plate 602 is reset to the bottom front end of the annular groove 6011, and the suction nozzle 603 is re-adsorbed on the wall of the oil storage tank.

[0042] Specifically, in order to ensure the normal operation of the scheme, the vertical height of the lifting block 608 of the present scheme gradually increases along the axial direction of the sliding groove towards the control module 606, and the lowest height of the lifting block 608 is flush with the bottom surface of the annular groove 6011 in the initial state; the end of the return spring 605 connected to the fixed plate 601 is located at the bottom of the end of the annular groove 6011 close to the control module 606.

[0043] Furthermore, the present solution also includes an ejection block and an ejection spring. The top front end of the annular groove 6011 is provided with an ejection slot hole, which is connected to the annular groove 6011. The ejection block can be lifted and lowered in the ejection slot hole. The two ends of the ejection spring are respectively connected to the ejection block and the ejection slot hole. The sliding plate 602 can lock or release its abutment and matching relationship with the ejection block. The purpose of the ejection block is to drive the sliding plate 602 to the bottom front end of the annular groove 6011. In order to ensure the structural effect of the ejection block, the vertical height of the ejection block of the present solution is gradually reduced along the axial direction of the sliding groove close to the control module 606. The lowest height of the ejection block is flush with the top surface of the annular groove 6011 in the initial state.

[0044] In addition, it is worth mentioning that the present solution is provided with two adsorption units 6. In order to ensure that the two adsorption units 6 do not release the adsorption relationship between the suction nozzle 603 and the oil tank wall at the same time, the lengths of the two annular grooves 6011 of the present solution are different.

[0045] The above embodiments all describe the situation when the mobile housing 1 moves along the direction of the sliding groove, that is, the situation when the mobile housing 1 moves straight; in addition, the mobile housing 1 also needs to have the ability to turn. Based on this, the present solution includes a steering assembly 7, which includes a rotating cylinder 701, a rotating suction cup 702 and a rotating pump 703. The rotating cylinder 701 is centrally arranged at the bottom center of the mobile housing 1, and the rotating cylinder 701 is located between the two adsorption units 6. The rotating suction cup 702 is rotatably connected to the output end of the rotating cylinder 701 coaxially, and the rotating pump 703 is connected to the mobile housing 1. The bottom of the rotating pump 703 is connected to the rotating suction cup 702 through a connecting pipe, and the rotating suction cup 702 can lock or release its adsorption relationship with the wall of the oil storage tank; by providing a steering assembly 7, the rotating cylinder 701 extends its output end to make the rotating suction cup 702 fit with the wall of the oil storage tank, and then the rotating pump 703 starts to work, so that the rotating suction cup 702 generates negative pressure, ensuring that the rotating suction cup 702 is adsorbed on the wall of the oil storage tank, and then by changing the rotation speed of the two rotating motors 504, the movable housing 1 is rotated around the center of the rotating suction cup 702. In addition, it should be noted that due to the presence of the suction nozzle 603, when the suction nozzle 603 is adsorbed on the wall of the oil storage tank, the mobile housing 1 cannot be turned. Based on this, the steering assembly 7 of this solution also includes a bogie 704, a pressing module 705 and a pressing rod 706. The bogie 704 is arranged at the bottom of the mobile housing 1, and the pressing module 705 is arranged on the bogie 704. The pressing module 705 is communicated with the two air pumps 604, and the pressing rod 706 is horizontally connected to the rotating cylinder 70 1, the pressing rod 706 can lock or release its pressing relationship with the pressing module 705; when the output end of the rotating cylinder 701 extends, the pressing rod 706 extends along with the output end of the rotating cylinder 701, and after the rotating suction cup 702 is adsorbed on the wall of the oil storage tank, the pressing rod 706 realizes its pressing relationship with the pressing module 705, and then the pressing module 705 controls the two air pumps 604 to stop working, so that the suction nozzle 603 is no longer adsorbed on the wall of the oil storage tank. It is worth noting that the rotating suction cup 702 of this solution has a retractable structure, and the distance between the rotating suction cup 702 and the wall of the oil storage tank is less than the distance between the pressing rod 706 and the pressing module 705. This setting ensures that the rotating suction cup 702 is first set in contact with the wall of the oil storage tank, and as the rotating cylinder 701 continues to extend, the pressing rod 706 realizes its pressing relationship with the pressing module 705.

[0046] A method for reinforcing the wall of an oil storage tank comprises the following steps:

[0047] S1: The movable housing 1 slides on the wall of the oil storage tank, and moves the welding assembly 2, the positioning assembly 3 and the pressing assembly 4 to the position of the wall of the oil storage tank to be reinforced;

[0048] S2: Use a hoist to lift the reinforcement plate to the vicinity of the position to be reinforced on the wall of the oil storage tank;

[0049] S3: The positioning mechanical claw grabs the reinforcement plate near the position to be reinforced and moves it to the positioning position of the oil storage tank wall;

[0050] S4: The pressing mechanical claw is used to press the reinforcement plate to fit the wall of the oil tank;

[0051] S5: Then the welding mechanical claw moves the output end of the welding equipment mounted thereon to the connection point between the reinforcing plate and the tank wall of the oil storage tank to perform welding processing, and the positioning mechanical claw stops working;

[0052] S6; then the mobile shell 1 moves along the direction of the connection between the reinforcement plate and the wall of the oil storage tank. The pressing mechanical claw presses the position of the reinforcement plate to be welded due to the movement of the mobile shell 1. The welding mechanical claw welds the connection between the reinforcement plate and the wall of the oil storage tank due to the movement of the mobile shell 1, thereby realizing the welding of the reinforcement plate to the wall of the oil storage tank.
