[0027] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0028] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0029] A bridge support processing device includes a workbench 1, on which a clamping structure is installed, and the clamping structure is provided in two numbers, and the two clamping structures are respectively arranged at both ends of the workbench 1, and the clamping structure includes a clamping base 2 slidably connected to the workbench 1, and a support spring 3 is installed between the clamping base 2 and the workbench 1. In the initial state, under the action of the support spring 3, the clamping base 2 is pushed toward the direction close to the upper end surface of the workbench 1, and two relatively sliding clamping blocks 4 are symmetrically arranged on the clamping base 2, and both sides of the bottom of the clamping block 4 are fixedly connected with a driving shaft 5, and a sliding groove 6 matching with the driving shaft 5 is opened on the clamping base 2, and the driving shaft 5 is slidably connected to the sliding groove 6 Inside, control plates 7 are slidably connected on both sides of the clamping base 2, and compression springs 8 are installed between the control plate 7 and the workbench 1. In the initial position, under the action of the compression springs 8, the control plate 7 is pushed toward the direction close to the upper end surface of the workbench 1. Two inclined driving grooves 9 are symmetrically arranged on the control plate 7. The driving grooves 9 are slidably connected to the driving shaft 5, and the driving shaft 5 is slidably connected inside the driving grooves 9. When in use, when the control plate 7 slides downward, the driving grooves 9 drive the driving shaft 5 to slide inside the sliding grooves 6, and synchronously drive the two relatively arranged clamping blocks 4 to slide toward each other; a limiting structure for limiting the height of the control plate 7 is provided on the control plate 7;

[0030] When in use, the steel pipe to be welded is placed on the upper end surface of the control plate 7. Under the gravity of the steel pipe itself, the control plate 7 is driven to slide downward, thereby pushing the clamping blocks 4 in the direction of approaching each other through the driving groove 9 and the driving shaft 5 until the steel pipe is clamped between the clamping blocks 4. After the clamping blocks 4 clamp the steel pipe, the two clamping blocks 4 cannot continue to slide in the direction of approaching each other. At this time, the steel pipe presses the clamping base 2 downward to slide downward until the steel pipe and the upper surface of the workbench are fitted. At this time, another steel pipe to be welded is placed on the workbench, and the two steel pipes are welded. The steel pipes can be rotated between the clamping blocks 4.

[0033] A plurality of support rollers 12 are rotatably connected to the workbench 1 and are distributed at intervals. The support rollers 12 are installed between two clamping bases 2. When in use, after the steel pipe is placed on the upper end face of the control panel 7, the steel pipe sticks to the outer surface of the support rollers 12 under the action of gravity and stops. At this time, after the clamping block 4 clamps the steel pipe, the steel pipe slides to both sides of the workbench 1 under the action of the support rollers 12, the support balls 11 and the limiting balls 10, reducing friction and facilitating adjustment of the welding position of the steel pipe.

[0034] The limiting structure includes a fixed block 13 fixedly connected to the side of the control board 7 away from the clamping base 2, the cross-section of the fixed block 13 is set to be a triangle, a support rod 14 is slidably connected to the workbench 1, a return spring 15 is installed between the support rod 14 and the workbench 1, a self-locking block 16 matching the fixed block 13 is slidably connected to the support rod 14, a self-locking spring is installed between the self-locking block 16 and the support rod 14, in the initial position, the self-locking block 6 is pushed to slide in the direction close to the control board 7 under the action of the self-locking spring, the cross-section of the self-locking block 16 is set to be a triangle, one end of all the support rods 14 is connected to the same control rod 39, when in use, when the control board 7 slides downward, the fixed The inclined surface of the card block 13 contacts the inclined surface of the self-locking card block 16, and then the fixed card block 13 pushes the self-locking card block 16 away from the control board 7 until the inclined surface of the fixed card block 13 and the inclined surface of the self-locking card block 16 are out of contact, and the horizontal surface of the fixed card block 13 and the horizontal surface of the self-locking card block 16 are in contact, thereby restricting the control board 7 from sliding upward; after use, pull the control rod 39, the control rod 39 drives the support rod 14 to slide synchronously, and the support rod 14 drives the self-locking card block 16 to slide synchronously, so that the self-locking card block 16 and the fixed card block 13 are out of contact, so that the control board 7 can slide freely, and under the action of the compression spring 8, the control board 7 is pushed in the direction close to the upper end surface of the workbench 1.

[0035] A plurality of clamping drive plates 17 are slidably connected to the workbench 1, a limiting block 18 is fixedly installed on the side of the clamping drive plate 17 close to the clamping base 2, an arc-shaped clamping groove 19 is provided on the side of the limiting block 18 away from the clamping drive plate 17, and a pushing structure is connected to the clamping drive plate 17, which is used to push the clamping drive plate 17 to slide.

[0036] The limiting block 18 is made of rubber material to increase friction.

[0037] The pushing structure includes a mounting plate 20 fixedly connected to the lower end surface of the workbench 1, and both sides of the mounting plate 20 are provided with limit grooves 21, and the cross section of the limit groove 21 is set to a triangle. A sliding plate 22 is slidably connected to the mounting plate 20, and both ends of the sliding plate 22 are slidably connected to a pushing block 23 that matches the limit groove 21, and the cross section of the pushing block 23 is set to a right-angle trapezoid. A pushing spring 24 is arranged between the pushing block 23 and the sliding plate 22. In the initial state, when in use, the pushing spring 24 pushes the pushing block 23 to approach the limit groove. When in use, the sliding plate 22 is pushed toward the upper end surface of the workbench 1, at which time the inclined surface of the pushing block 23 contacts the inclined surface of the limiting groove 21, and the inclined surface of the limiting groove 21 slides the pushing block 23 away from the limiting groove 21 until the inclined surface of the limiting groove 21 and the inclined surface of the pushing block 23 are out of contact, so that the horizontal surface of the pushing block 23 and the inclined surface of the limiting groove 21 fit together, so that the limiting groove 21 limits the pushing block 23 at the current position, and the pushing block 23 limits the sliding plate 22 at the current position;

[0038] A guide groove 25 is provided on the push block 23, and the cross section of the guide groove 25 is set to be triangular. A driving rod 26 is slidably connected to the sliding plate 22, and a guide block 27 matched with the guide groove 25 is fixedly connected to the driving rod 26. A pressing pedal 28 is rotatably connected to the mounting plate 20, and a pushing groove 29 is provided at one end of the pressing pedal 28 close to the sliding plate 22. A sliding shaft 30 matched with the pushing groove 29 is fixedly connected to the driving rod 26, and a connecting rod is connected between the sliding plate 22 and the pressing driving plate 17;

[0039] When in use, the clamping pedal 28 is pressed downward to move away from one end of the sliding plate 22, and the other end of the clamping pedal 28 drives the sliding shaft 30 to slide upward through the pushing groove 29, and at the same time drives the driving rod 26 to slide upward, and the driving rod 26 drives the sliding plate 22 to slide upward, thereby driving the clamping driving plate 17 to slide in the direction close to the control plate 7 through the connecting rod, so that the clamping groove 19 clamps the steel pipe, thereby fixing the steel pipe in the current position to prevent sliding during the welding process. After use, the clamping pedal 28 is lifted upward to move away from one end of the sliding plate 22, so that the other end of the clamping pedal 28 drives the sliding shaft 30 to slide downward through the pushing groove 29, so that the inclined surface of the guide block 27 contacts the inclined surface of the guide groove 25, and the guide block 27 pulls the pushing block 23 to slide in the direction away from the guide groove 25, so that the limiting groove 21 and the pushing block 23 are out of contact. At this time, the sliding plate 22 can slide up and down, so that the clamping groove 19 and the steel pipe to be welded are separated.

[0040] The baffle plate 31 is slidably connected to the workbench 1, and a guide groove is provided on the workbench 1. A clamping bolt passing through the guide groove is fixedly connected under the baffle plate 31, and a nut is threadedly connected to the clamping bolt, so that the baffle plate 31 is fixed in the current position by the clamping bolt and the nut, and a top clamping plate 32 is slidably connected to the workbench 1, and a clamping spring 33 is connected between the top clamping plate 32 and the workbench 1, and a plurality of clamping plates 34 are rotatably connected to the top clamping plate 32, and a torsion spring is installed between the clamping plate 34 and the top clamping plate 32. When in use, the torsion spring pushes the clamping plate 34 to rotate in the direction close to the clamping plate 32. When the clamping plate 34 is attached to the steel pipe, the clamping plate 34 and the steel pipe are continuously pushed to fit together under the action of the clamping spring 33, so that the steel pipe placed near the baffle plate 31 is pushed in the direction close to the steel pipe fixed inside the clamping block 4, so that the welding joints of the two steel pipes fit together;

[0041] When in use, pull the clamping plate 32 away from the baffle 31, place another steel pipe to be welded on the workbench 1, so that the steel pipe and the baffle 31 fit together, loosen the clamping plate 32, and under the action of the clamping spring 33, push the clamping plate 32 to slide towards the baffle 31, so that the clamping plate 34 and the steel pipe fit together, and then push the steel pipe placed near the baffle 31 towards the steel pipe fixed inside the clamping block 4, so that the welding points of the two steel pipes fit together.

[0042] A connecting rod 35 is slidably connected to the workbench 1, and a tension spring is connected between the connecting rod 35 and the workbench 1. One end of the connecting rod 35 is fixedly connected to a top plate 36. In the initial position, the top plate 36 is pulled to slide in the direction close to the workbench 1 under the action of the tension spring. A tape measure 37 is installed on the workbench 1, and one end of the ruler inside the tape measure 37 is fixedly connected to the connecting rod 35. A marking port 38 is opened on the workbench 1. When in use, when the steel pipe is restricted inside the clamping block 4, one end of the steel pipe contacts the top plate 36, pushing the steel pipe to slide, so that the steel pipe pushes the top plate 36 to slide in the direction away from the workbench 1, thereby driving the connecting rod 35 to slide synchronously, and the ruler is pulled out from the inside of the tape measure 37, and a reading is taken at the marking port 38, so as to determine the position where the steel pipe needs to be welded.

[0043] When implementing

[0044] The steel pipe to be welded is placed on the upper end surface of the control plate 7. Under the gravity of the steel pipe itself, the control plate 7 is driven to slide downward, thereby pushing the pressing blocks 4 in the direction of approaching each other through the driving groove 9 and the driving shaft 5 until the steel pipe is pressed between the pressing blocks 4. After the pressing blocks 4 press the steel pipe, the two pressing blocks 4 cannot continue to slide in the direction of approaching each other. At this time, the steel pipe presses the pressing base 2 downward to slide downward until the steel pipe fits the upper surface of the workbench. At this time, another steel pipe to be welded is placed on the workbench;

[0045] Pull the top plate 32 away from the baffle 31, place another steel pipe to be welded on the workbench 1, make the steel pipe and the baffle 31 fit together, loosen the top plate 32, and push the top plate 32 to slide towards the baffle 31 under the action of the clamping spring 33, so that the clamping plate 34 and the steel pipe fit together, and then push the steel pipe placed on the baffle 31 towards the steel pipe fixed inside the clamping block 4, so that the welding parts of the two steel pipes fit together;

[0046] When the steel pipe is confined inside the clamping block 4, one end of the steel pipe contacts the top plate 36, pushing the steel pipe to slide, so that the steel pipe pushes the top plate 36 to slide away from the workbench 1, thereby driving the connecting rod 35 to slide synchronously, and the ruler is pulled out from the inside of the tape measure 37, and a reading is taken at the marking port 38 to determine the position where the steel pipe needs to be welded.

[0047] Press down the clamping pedal 28 away from one end of the sliding plate 22, and the other end of the clamping pedal 28 drives the sliding shaft 30 to slide upward through the pushing groove 29, and at the same time drives the driving rod 26 to slide upward, and the driving rod 26 drives the sliding plate 22 to slide upward, thereby driving the clamping driving plate 17 to slide in the direction close to the control plate 7 through the connecting rod, so that the clamping groove 19 clamps the steel pipe, thereby fixing the steel pipe in the current position to prevent sliding during welding.

[0048] After welding is completed, the clamping pedal 28 is lifted upwards away from one end of the sliding plate 22, so that the other end of the clamping pedal 28 drives the sliding shaft 30 to slide downward through the pushing groove 29, so that the inclined surface of the guide block 27 contacts the inclined surface of the guide groove 25, and the guide block 27 pulls the pushing block 23 to slide in the direction away from the guide groove 25, so that the limit groove 21 and the pushing block 23 are out of contact. At this time, the sliding plate 22 can slide up and down to separate the clamping groove 19 from the steel pipe to be welded.

[0049] At this time, the steel pipe confined in the clamping block 4 can rotate freely, exposing the unwelded side of the steel pipe for easy welding. Pressing the clamping pedal 28 downward makes the clamping groove 19 clamp the steel pipe. After welding is completed, the welded steel pipe is removed from the workbench 1.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
