DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 5 , a track beam welding positioning device includes two base plates 1, one side of the two base plates 1 is fixed with an L-shaped plate 2 by bolts, a cross-shaped rod 3 is fixed between the L-shaped plates 2 by bolts, the outer side of the cross-shaped rod 3 is slidably connected to two cross-shaped sliders 4, and a detachable fixing component is provided between the cross-shaped rod 3 and the cross-shaped slider 4, which is convenient for the staff to adjust the position of the cross-shaped slider 4, the top of the cross-shaped slider 4 is fixed with a connecting block 5 by bolts, and the top of the connecting block 5 is fixed with a square frame 7 by bolts. The inside of the frame 7 is rotatably connected with a two-way threaded rod 8, and the outer side of the two-way threaded rod 8 is threadedly connected to two slides 9. The slide 9 slides along the inside of the frame 7, and the track beam is placed on the two frames 7. The two-way threaded rod 8 is rotated to drive the two slides 9 to the center. The power assembly causes the slide bar 17 to drive the splint 19 on the connecting rod 18 to move until the splint 19 is in close contact with the side of the mounting plate of the reducer support. At this time, the track beam component and the reducer support are stably connected, and the staff can weld the track beam and the reducer support.

[0025] In the present invention, it should be noted that the fixing assembly includes a plurality of sockets 6, which are provided on one side of the cross-shaped rod 3, and two through holes 13 connected up and down are provided on both sides of the cross-shaped slider 4. A latch 20 is inserted between the two through holes 13 connected up and down, and the latch 20 is plugged into the socket 6. When it is necessary to adjust the distance between the two connecting blocks 5, the latch 20 is removed from the through hole 13 and the socket 6, and the connecting block 5 is pushed to move it along the cross-shaped slider 4 along the cross-shaped rod 3 until the spacing between the two connecting blocks 5 is the required distance, thereby enabling the device to be suitable for crawler beams of different sizes. The power assembly includes a multi-section electric push rod 15, which is fixed to the cavity by bolts. On one side of 14, the extended end of the multi-section electric push rod 15 is fixed with a slide plate 16 by bolts, and the slide plate 16 is fixed to the slide rod 17. When the multi-section electric push rod 15 is started, the multi-section electric push rod 15 is extended and retracted to make the slide plate 16 move along the cavity 14, thereby driving the slide rod 17 to move. The top and bottom of the cross-shaped slider 4 are provided with avoidance grooves 11, and the avoidance grooves 11 are rotatably connected to two rotating rods 12. The rotating rods 12 are in contact with the cross-shaped rod 3. During the movement of the cross-shaped slider 4, the rotating rod 12 rotates, thereby making the cross-shaped slider 4 move more smoothly along the cross-shaped rod 3. One end of the bidirectional threaded rod 8 passes through the connecting block 5 and is welded with a rotating disk 10, which is convenient and labor-saving to rotate the bidirectional threaded rod 8.

[0026] Working principle: When it is necessary to dock the track beam component with the reducer support, first place the track beam on the two frames 7, turn the rotating disk 10, so that the bidirectional threaded rod 8 drives the two slides 9 to move along it toward the middle until the slide 9 contacts the side of the track beam, so that the track beam is clamped and positioned, and then the mounting surface of the reducer support is brought into contact with the mounting surface of the track beam, start the multi-section electric push rod 15, and the multi-section electric push rod 15 contracts to make the slide plate 16 move along the cavity 14, so that the slide rod 17 drives the splint 19 on the connecting rod 18 to move until the splint 19 is in close contact with the side of the mounting plate of the reducer support. At this time, the track beam component and the reducer support are stably connected, and the staff can weld the track beam and the reducer support.

[0027] Furthermore, the terms "installed," "disposed," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
