Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to a steel pipe pile welding device and a welding method for a bridge tower crane foundation. Background Art

[0002] Bridge tower crane is the specific application form of tower crane in bridge construction projects. It is a lifting machinery belonging to the category of special equipment. It is mainly used for vertical lifting and horizontal transportation of materials in bridge construction. When installing a bridge tower crane, a deep foundation structure is required to provide basic support for the construction of the tower crane. Its essence is a pile foundation system constructed with high-strength steel pipes as the main body. The tower crane load is transferred to the deep stable stratum through the interaction between the pile body and the foundation.

[0003] When constructing steel pipe pile foundations, the steel pipes are welded using an electric welding machine. During operation, the welding machine dissipates heat through multiple heat dissipation holes, while a cooling fan continuously extracts hot air from the welding machine, thereby circulating the air inside the welding machine and ensuring efficient heat dissipation. However, in actual operation, due to the complex construction site environment and the fact that the steel pipe piles are installed outdoors, debris such as cardboard and snakeskin bags on the construction site are blown onto the welding machine, blocking the heat dissipation holes and preventing air from entering the welding machine. This significantly reduces the airflow from the heat dissipation area, making it impossible for the welding machine to dissipate heat. This can easily lead to the welding machine burning out due to overheating. Furthermore, if a bridge is built near a water source or in a humid area, or if construction is carried out in humid weather, the welding machine is prone to short circuiting due to excessive humidity when it enters the airflow.

[0026] A method for welding steel pipe piles for bridge tower crane foundations is performed according to the above-mentioned device for welding steel pipe piles for bridge tower crane foundations, and comprises the following steps:

[0027] S1. The welding host is covered, and the wind force blown by the cooling fan is weakened. Under the rebound force of the return spring, the force-bearing push frame drives the transfer push frame to reset. The transfer push frame drives the two transfer rods to rotate through the two push sliding shafts. The transfer rods rotate on one side of the welding host through a push-pull shaft, and the transfer rods drive the push-pull seat to move through the other push-pull shaft, and then drive the debris removal push frame to move through the push-pull seat, and the debris removal push frame pushes away the debris;

[0028] S2. The transfer push frame moves, driving the two synchronous drive rods to move. The two synchronous drive rods move in the two drive slots, and then drive the two drive columns to rotate. The drive columns drive the flip cover to rotate through the synchronous shaft, so that the auxiliary heat dissipation holes are opened for auxiliary heat dissipation;

[0029] S3. The welding host dissipates heat and absorbs moisture from the air through the desiccant in the drying hood. As the desiccant absorbs more and more water, the mass of the drying hood gradually increases, and the pressure plate moves in the downward groove. The movement of the drying hood drives the synchronous frame to move, and the downward movement of the synchronous frame drives the locking block to disengage from the locking slot. Under the rebound force of the separation spring, the separation frame pops out and the power plug is disconnected, causing the welding host to be shut down urgently.

[0030] S4. The welding machine is placed on the ground so that the compression wheel is squeezed by the ground, driving the compression rod to retract into the compression groove, and driving the expansion spring to be compressed. The compression rod moves through the follower groove to drive the follower block to move, and then drives the support frame to rotate. The support frame rotates through the two support shafts to move in the two support grooves, and then drives the two splash guards to unfold. The splash guards slide on the welding machine through two transverse sliding frames. At the same time, the two splash guards unfold and drive the folding sleeve to unfold to form a protective cover.

[0031] The beneficial effects of the steel pipe pile welding device and welding method for bridge tower crane foundation proposed by the present invention are:

[0032] In the present invention, through the setting of the active de-dusting mechanism, during the normal heat dissipation process of the electric welding host, if the electric welding host is blocked and the electric welding host cannot fully take in air, the airflow blown out by the cooling fan is greatly reduced. Therefore, under the rebound force of the return spring, the force-bearing push frame is reset, and then the adapter push frame drives the de-dusting push frame to move through the two adapter rods, and pushes away garbage bags or cardboard, wooden boards and other debris, thereby ensuring the air intake and heat dissipation of the electric welding host; at the same time, when the adapter push frame moves and drives the two synchronous drive rods to move, the two synchronous drive rods move in the two drive grooves, and then drive the two drive columns to rotate, and the drive columns drive the flip cover plate to rotate through the synchronous rotating shaft, so that the auxiliary heat dissipation holes are opened for auxiliary heat dissipation, thereby avoiding the problem of damage caused by overheating of the electric welding host.

[0033] Furthermore, in the present invention, through the setting of the emergency stop mechanism due to moisture, when the welding host is dissipating heat, the incoming air is filtered by the drying hood, and at the same time, the moisture in the air is absorbed by the desiccant. As the desiccant absorbs more and more water, the mass of the drying hood gradually increases, and it moves in the downward groove through the pressure plate. The movement of the drying hood drives the movement of the synchronization frame, and the downward movement of the synchronization frame drives the locking block to disengage from the locking slot. At this time, under the rebound force of the separation spring, the separation frame is driven to pop out, and the power plug is separated, and the welding host is emergency stopped to avoid the problem of short circuit or even fire or explosion caused by moisture of the welding host.

[0034] Furthermore, in the present invention, through the setting of the splash protection mechanism, when the welding host is in protection, the compression wheel is squeezed by the ground, driving the compression rod to retract into the compression groove, and the compression rod moves through the follower groove to drive the follower block to move, thereby driving the support frame to rotate, and the support frame is pulled to move in the two support grooves through the two support shafts, thereby driving the two splash guards to unfold, and the unfolding of the two splash guards drives the folding sleeve to unfold to form a protective cover, thereby avoiding problems such as splashing mud and water on the welding host when in use, and at the same time does not affect the heat dissipation and use of the welding host.

[0057] Please refer to the attached manual Figures 1-15 An embodiment of the present invention provides a steel pipe pile welding device for a bridge tower crane foundation, which includes an electric welding host 1. A plurality of heat dissipation holes 2 are provided on both sides and the front of the electric welding host 1. A heat dissipation fan 3 is installed on the back of the electric welding host 1 and is plugged with a power plug 4.

[0058] For further information, please refer to the attached manual. Figure 3-Figure 7The embodiment of the present invention provides a steel pipe pile welding device for a bridge tower crane foundation. An active debris removal mechanism 5 is installed on the welding main unit 1. The active debris removal mechanism 5 is used to push away debris that falls on the welding main unit 1; the active debris removal mechanism 5 includes a debris removal pushing frame 501, which is slidably installed on the welding main unit 1. The debris removal pushing frame 501 slides to push away the debris that falls on the welding main unit 1. Adapter rods 504 are rotatably installed on both sides of the welding main unit 1. The two adapter rods 504 are movably installed on the debris removal pushing frame 501. A mounting frame 502 is installed on the back of the welding main unit 1. A transfer pushing frame 503 is movably installed on the mounting frame 502. The transfer pushing frame 503 is movably connected to the two transfer rods 504. The transfer pushing frame 503 moves to push the transfer rod 504 to rotate, so as to drive the debris removal pushing frame 501 to move and remove debris. It should be noted that, in the embodiment of the present invention, when garbage bags, cardboard, wooden boards and other debris cover the welding host 1, causing it to be unable to dissipate heat, the adapter push frame 503 drives the two adapter rods 504 to rotate, and the adapter rods 504 drive the debris removal push frame 501 to move, pushing away the debris, thereby ensuring normal air intake and heat dissipation of the welding host 1.

[0059] Furthermore, in an embodiment of the present invention, it also includes an emergency stop mechanism 6 when it is damp, which is installed in multiple heat dissipation holes 2 on the welding host 1. When the welding host 1 is damp, the power plug 4 is unplugged through the emergency stop mechanism 6 when it is damp, and the welding host 1 is emergency stopped; specifically, the emergency stop mechanism 6 when it is damp includes three drying covers 601, and the two sides of the drying covers 601 are mesh-shaped, and the drying covers 601 are filled with desiccant. The three drying covers 601 are respectively movably installed on the two sides and the front of the welding host 1, and synchronization frames 602 are movably installed on the three drying covers 601. A separation frame 606 is movably installed on the back of the welding host 1, and the separation frame 606 is used to unplug the power plug 4, and the synchronization frame 602 is used to lock the separation frame 606. It should be noted that, in the embodiment of the present invention, when the welding host 1 is dissipating heat, the incoming air is filtered by the drying hood 601, and the moisture in the air is absorbed by the desiccant. As the desiccant absorbs more and more water, the mass of the drying hood 601 gradually increases, driving the synchronization frame 602 to separate from the separation frame 606, thereby causing the separation frame 606 to pop out and separate the power plug 4, thereby causing the welding host 1 to be shut down urgently, avoiding the problem of short circuit or even fire or explosion caused by moisture in the welding host 1.

[0060] Please continue to refer to the instructions attached Figure 3-Figure 7 Furthermore, in an embodiment of the present invention, a steel pipe pile welding device for a bridge tower crane foundation is provided.

A synchronous driving rod 515 is movably installed in the driving groove 516, and the synchronous driving rod 515 is installed on the transfer push frame 503. It should be noted that in the embodiment of the present invention, when the transfer push frame 503 moves, the two synchronous driving rods 515 are driven to move, and the two synchronous driving rods 515 move in the two driving grooves 516, thereby driving the two driving columns 514 to rotate, and the driving column 514 drives the flip cover 512 to rotate through the synchronous shaft 513, so that the auxiliary heat dissipation holes 517 are opened for auxiliary heat dissipation, so as to achieve the effect of auxiliary heat dissipation when the welding host 1 is covered by debris and the welding host 1 cannot dissipate heat.

[0062] More specifically, in the embodiment of the present invention, a force-bearing push frame 505 is movably installed in the mounting frame 502. The force-bearing push frame 505 is arranged corresponding to the position of the heat dissipation fan 3, and the adapter push frame 503 is installed on the force-bearing push frame 505. A return spring 506 is installed on one side of the force-bearing push frame 505, and the other end of the return spring 506 is installed on the inner wall of the mounting frame 502. It should be noted that in the embodiment of the present invention, when the heat dissipation fan 3 is normally dissipating heat, the heat dissipation fan 3 blows air to drive the force-bearing push frame 505 to move, and the force-bearing push frame 505 drives the adapter push frame 503 to move, and then drives the impurity removal push frame 501 to move. At the same time, the force-bearing push frame 505 drives the return spring 506 to be stressed, so that the rebound force of the return spring 506 can help the force-bearing push frame 505 to reset.

[0063] More specifically, in the embodiment of the present invention, the two transfer rods 504 are each provided with a push slide hole 507 , and the transfer push frame 503 is rotatably mounted with two push slide shafts 508 , which are movably mounted in the two push slide holes 507 ;

[0064] In addition, two push-pull seats 509 are slidably mounted on the impurity removal push frame 501, and two push-pull shafts 510 are mounted on the transfer rod 504, and the two push-pull shafts 510 are rotatably mounted on the welding host 1 and the push-pull seat 509. It should be noted that in the embodiment of the present invention, when the transfer push frame 503 moves, the two transfer rods 504 are driven to rotate by the two push sliding shafts 508, and at the same time, the push sliding shafts 508 slide in the push sliding hole 507, the transfer rod 504 rotates on one side of the welding host 1 through a push-pull shaft 510, and the transfer rod 504 drives the push-pull seat 509 to move through the other push-pull shaft 510, and then drives the impurity removal push frame 501 to move through the push-pull seat 509, thereby achieving the purpose of pushing away the debris.

[0065] Please refer to the attached manual Figure 3-Figure 4 and Figures 8-10 Furthermore, an embodiment of the present invention provides a welding device for steel pipe piles for bridge tower crane foundations, in which downward displacement grooves 604 are provided on the front and both sides of the electric welding main unit 1, and a pressure plate 603 is movably installed in the downward displacement groove 604, and the pressure plate 603 is installed on the drying hood 601; in addition, a support spring 605 is installed on the bottom side of the pressure plate 603, and the bottom end of the support spring 605 is installed on the bottom inner wall of the downward displacement groove 604. It should be noted that in the embodiment of the present invention, when the pressure plate 603 moves, it moves vertically in the downward displacement groove 604 and drives the support spring 605 to be compressed. Therefore, when the drying hood 601 is drying, the drying hood 601 can be supported by the pressure plate 603 under the rebound force of the support spring 605.

[0066] More specifically, in the embodiment of the present invention, a stretching slot 609 is defined on the back of the welding host 1. One side of the separation frame 606 extends into the stretching slot 609 and is equipped with a separation spring 610. The other end of the separation spring 610 is mounted on the inner wall of the stretching slot 609. In addition, a locking slot 607 is defined on the bottom side of the separation frame 606. A locking block 608 is mounted on the top side of the synchronization frame 602. The locking block 608 is inserted into the locking slot 607 to lock the separation frame 606. It should be noted that in the embodiment of the present invention, when the drying hood 601 moves downward due to moisture, the movement of the drying hood 601 drives the synchronization frame 602 to move. The downward movement of the synchronization frame 602 drives the locking block 608 to disengage from the locking slot 607. At this time, under the rebound force of the separation spring 610, the separation frame 606 is ejected and the power plug 4 is separated, thereby causing the welding host 1 to be shut down in an emergency and preventing the welding host 1 from short-circuiting due to moisture.

[0067] Please refer to the attached manual Figure 11-Figure 15 Furthermore, the embodiment of the present invention provides a steel pipe pile welding device for a bridge tower crane foundation, further comprising a splash protection mechanism 7, which is mounted on the bottom side of the welding main unit 1 and is used to shield and protect the welding main unit 1. It should be noted that in the embodiment of the present invention, when the welding main unit 1 is placed, the two splash shields 701 unfold and drive the folding sleeve 702 to unfold to form a protective shield, thereby preventing a large amount of muddy water from splashing into the welding main unit 1 when the welding main unit 1 is in use, thereby ensuring the safe use of the welding main unit 1.

[0068] More specifically, in the embodiment of the present invention, the splash protection mechanism 7 includes two splash shields 701, which are movably mounted on the front and back of the welding host 1, respectively, and a foldable folding sleeve 702 is connected between the two splash shields 701; two transverse sliding frames 703 are installed in the splash shield 701, and the transverse sliding frames 703 are slidably mounted on the welding host 1, and support feet 713 are installed at the four corners of the bottom side of the splash shield 701;

[0069] In addition, a support frame 708 is rotatably mounted on the bottom side of the welding main unit 1, and two support shafts 711 are rotatably mounted on the support frame 708. A support groove 712 is provided on each of the two splash shields 701, and the two support shafts 711 are movably mounted in the two support grooves 712. It should be noted that in the embodiment of the present invention, when the welding main unit 1 is placed, the compression rod 704 is squeezed and retracted, thereby driving the support frame 708 to rotate, and the support frame 708 rotates to move in the two support grooves 712 through the two support shafts 711, thereby driving the two splash shields 701 to unfold, and the splash shields 701 slide horizontally on the welding main unit 1 through the two transverse sliding frames 703. At the same time, the two splash shields 701 unfold and drive the folding sleeve 702 to unfold to form a protective cover.

[0070] Please continue to refer to the instructions attached Figure 11-Figure 15 More specifically, in the embodiment of the present invention, a compression groove 706 is formed on the bottom side of the welding host 1, an expansion spring 707 is installed on the top inner wall of the compression groove 706, a compression rod 704 is installed at the bottom end of the expansion spring 707, a compression wheel 705 is rotatably installed on the compression rod 704, and a support frame 708 is movably connected to the compression rod 704;

[0071] In addition, an arc-shaped follower groove 709 is provided on the compression rod 704, and a follower block 710 is installed on the inner wall of the support frame 708, and the follower block 710 extends into the follower groove 709. It should be noted that in the embodiment of the present invention, when the electric welding host 1 is placed on the ground, the compression wheel 705 is squeezed by the ground, thereby driving the compression rod 704 to retract into the compression groove 706, and driving the expansion spring 707 to be compressed. The compression rod 704 moves through the follower groove 709 to drive the follower block 710 to move, and then drives the support frame 708 to rotate. The rotation of the support frame 708 drives the two splash shields 701 to unfold through the two support shafts 711, and at the same time drives the folding sleeve 702 to unfold to form a protective cover, thereby preventing the electric welding host 1 from being splashed with mud and water.

[0072] In summary, the working principle of a steel pipe pile welding device for a bridge tower crane foundation provided by an embodiment of the present invention, that is, the welding method using the steel pipe pile welding device of the embodiment of the present invention is as follows:

[0073] During the normal heat dissipation process of the welding host 1, the cooling fan 3 draws out the hot air in the welding host 1 for heat dissipation by blowing. The wind blown by the cooling fan 3 moves the force-bearing push frame 505, and the force-bearing push frame 505 drives the transfer push frame 503 to move, and drives the return spring 506 to be stressed. The transfer push frame 503 drives the two transfer rods 504 to rotate through the two push sliding shafts 508, and at the same time pushes the sliding shaft 508 to slide in the push sliding hole 507. The transfer rod 504 rotates on one side of the welding host 1 through a push-pull shaft 510, and the transfer rod 504 drives the push-pull seat 509 to move through another push-pull shaft 510, and then drives the push-pull seat 509 to move. The debris removal push frame 501 moves, and the debris removal push frame 501 is close to the electric welding host 1. At the same time, the push-pull seat 509 slides on the debris removal push frame 501. Therefore, once the electric welding host 1 is in use, garbage bags or cardboard, wooden boards and other debris on the construction site fall on the electric welding host 1, resulting in the electric welding host 1 being unable to fully intake air, which will greatly reduce the air flow blown out by the cooling fan 3. Therefore, under the rebound force of the return spring 506, the force-bearing push frame 505 is reset, and then the transfer push frame 503 drives the debris removal push frame 501 to move through the two transfer rods 504, thereby pushing away the garbage bags or cardboard, wooden boards and other debris, thereby ensuring the intake and heat dissipation of the electric welding host 1;

[0074] In addition, when the transfer push frame 503 moves and drives the two synchronous drive rods 515 to move, the two synchronous drive rods 515 move in the two drive slots 516, thereby driving the two drive columns 514 to rotate. The drive columns 514 drive the flip cover plate 512 to rotate through the synchronous rotating shaft 513, so that the auxiliary heat dissipation holes 517 are opened to assist in heat dissipation, thereby avoiding the problem of damage caused by overheating of the electric welding host 1;

[0075] Furthermore, when the welding host 1 is dissipating heat, the incoming air is filtered by the drying hood 601, and at the same time, the moisture in the air is absorbed by the desiccant. As the desiccant absorbs more and more water, the mass of the drying hood 601 gradually increases, and when the pressure plate 603 moves in the downward groove 604, the support spring 605 is compressed at the same time. The movement of the drying hood 601 drives the synchronous frame 602 to move, and the downward movement of the synchronous frame 602 drives the locking block 608 to disengage from the locking slot 607. At this time, under the rebound force of the separation spring 610, the separation frame 606 is driven to pop out and the power plug 4 is separated, thereby performing an emergency shutdown of the welding host 1 to avoid the problem of short circuit or even fire or explosion caused by moisture in the welding host 1.

[0076] Furthermore, when the welding host 1 is placed, the compression wheel 705 is squeezed by the ground, driving the compression rod 704 to retract into the compression groove 706, and driving the expansion spring 707 to be compressed. The compression rod 704 moves through the follower groove 709 to drive the follower block 710 to move, and then drives the support frame 708 to rotate. The support frame 708 rotates through the two support shafts 711 and moves in the two support grooves 712, thereby driving the two splash guards 701 to unfold. The splash guard 701 slides on the welding host 1 through the two transverse sliding frames 703. At the same time, the two splash guards 701 unfold and drive the folding sleeve 702 to unfold to form a protective cover, thereby avoiding problems such as splashing mud and water on the welding host 1 when in use, and at the same time does not affect the heat dissipation and use of the welding host 1.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
