Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding equipment for pile foundation steel cages. Background Technology

[0002] A pile foundation reinforcement cage refers to a cage-like structure made by weaving steel bars into the pile hole according to design requirements during the construction of concrete cast-in-place piles, bored cast-in-place piles, etc. Its main functions are to increase the tensile bearing capacity of the pile body, increase the bearing capacity of the pile top, and improve the bond strength between the pile foundation and the soil. Commonly used welding equipment in the welding process of pile foundation reinforcement cages includes reinforcement cage welding machines and auxiliary welding devices.

[0003] When using welding equipment, several reinforcing bars are first inserted sequentially into the main reinforcement holder of the welding equipment. During equipment operation, the several main reinforcement bars arranged in a ring are wrapped with stirrups. Then, a welding gun is set on one side of the main reinforcement bars to weld and fix the connection between the stirrups and the main reinforcement bars. However, when using this welding gun, it can only perform welding operations on the outside of the column formed by the several main reinforcement bars. Therefore, the welding gun can only weld on one side of the connection between the main reinforcement bars and the stirrups. In order to make the pile foundation reinforcement cage more robust, it is necessary to weld again on the inside of the connection between the two. Due to the lack of a support bracket to support the welding gun, it is impossible to install the corresponding welding gun. Therefore, manual welding can only be used. As a result, workers can only perform welding operations on the connection from inside the column formed by the several main reinforcement bars, which reduces welding efficiency and increases the labor intensity of workers.

[0004] Based on the above situation, it is necessary to design a welding device for pile foundation reinforcement cages to solve the above problems. Utility Model Content

[0005] This utility model provides a welding device for pile foundation reinforcement cages to solve the problem of low welding efficiency in the prior art when workers perform welding operations on the connection points inside a column formed by several main reinforcement bars.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A welding device for a pile foundation reinforcement cage includes an annular fixture, and further includes: a support column connected to the center line of the fixture, with an annular frame connected to the end of the support column away from the fixture, and the inner diameter of the annular frame being smaller than the inner diameter of the fixture; an annular track connected to the annular frame, with a moving mechanism on the annular track that moves along the annular track, a welding torch connected to the moving mechanism, and the output end of the welding torch being radially away from the axis of the annular frame; and a driving component for driving the moving mechanism to move on the annular track.

[0008] Preferably, the moving mechanism includes a device plate disposed on one side of the ring frame and a limiting wheel connected to the device plate via a rotating shaft, the limiting wheel being in contact with the outer wall of the ring track.

[0009] Preferably, the moving mechanism further includes a slider connected to the side of the device plate near the ring frame, the slider being in contact with the inner wall of the ring frame.

[0010] Preferably, the driving component includes an internal gear ring connected to the side of the annular track away from the annular frame, a mounting plate connected to the device plate, a drive motor mounted on the mounting plate, and a gear connected to the output end of the drive motor, the gear meshing with the internal gear ring.

[0011] Preferably, a lifting frame is connected to the side of the device plate away from the annular frame, the lifting frame is provided with a sliding groove, a connecting block is slidably connected to the sliding groove, and the welding gun is connected to the connecting block.

[0012] Preferably, a lifting channel is formed between the lifting frame and the device plate. The lifting frame has an elongated groove, and a connecting plate is slidably connected in the elongated groove. One end of the connecting plate is connected to a connecting block. A fixing plate is connected to the device plate, a load-bearing plate is connected to the fixing plate, and a telescopic rod is connected to the load-bearing plate. The movable end of the telescopic rod is connected to the other end of the connecting plate.

[0013] Preferably, the fixing plate has a plurality of positioning holes, and the load-bearing plate is connected to the positioning holes by bolts.

[0014] The beneficial effects of this utility model are as follows: by setting the support column and the ring frame inside the columnar structure formed by several main ribs, the moving mechanism will be inside the columnar structure when it drives the welding gun equipment to move on the ring track. This allows the welding gun equipment to effectively perform welding operations on the welding points that coincide between the main ribs and the stirrups. Furthermore, the welding operation is more accurate and convenient under the action of the telescopic rod. Compared with manual welding operations, this structure combined with the welding gun equipment is more efficient and convenient for welding operations, greatly reducing the labor intensity of workers.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] Reference Figures 1-8As shown, a welding device for pile foundation reinforcement cages includes an annular fixture 1. This fixture 1 is a part of the structure of welding equipment in the prior art, mainly used to install and fix several main reinforcement bars. Its annular shape facilitates rotation. The structure and operation are not described in detail here. The device also includes: a support column 2 connected to the center line of the fixture 1; an annular frame 3 connected to the end of the support column 2 away from the fixture 1, with the inner diameter of the annular frame 3 being smaller than the inner diameter of the fixture 1; an annular track 4 connected to the annular frame 3; a moving mechanism that moves along the annular track 4; a welding torch device 6 connected to the moving mechanism; and the output end of the welding torch device 6 being radially away from the axis of the annular frame 3; and a driving component for driving the moving mechanism to move on the annular track 4.

[0027] In use, the support column 2 is connected to the fixture 1. Different lengths of support columns 2 can be selected as needed. Then, the ring frame 3 is connected to the support column 2. Next, the welding torch device 6 is connected to the moving mechanism. Then, a drive unit is used to drive the moving mechanism to move on the ring track 4, with the movement trajectory being a circular motion centered on the central axis of the ring track 4. When the fixture 1 is driven to rotate by the welding equipment, it in turn drives the support column 2 to rotate, thereby driving the moving mechanism and the welding torch device 6 on the moving mechanism to move synchronously. To ensure that the output end of the welding torch device 6 is always at a certain radial position, therefore... This driving component will drive the moving mechanism to rotate in the opposite direction, eliminating the influence of the rotation of the fixing device 1 on the welding gun equipment 6. At this time, the welding points that coincide between the main ribs and the stirrups will continuously pass through the output end of the welding gun equipment 6, and the welding gun equipment 6 will continuously perform welding operations on the welding points that pass through its output end, thereby completing the welding operation of the connection from inside the column formed by several main ribs. It also provides a support structure for the welding gun equipment 6 to be set inside the column structure and perform welding operations. Compared with the manual welding operation of the connection, this structure, in conjunction with the welding gun equipment 6, is more efficient and convenient, greatly reducing the labor intensity of workers.

[0028] The moving mechanism includes a device plate 7 set on one side of the ring frame 3 and a limiting wheel 9 connected to the device plate 7 via a rotating shaft 8. The limiting wheel 9 is in contact with the outer wall of the ring track 4 and is connected to the ring track 4. Therefore, when the limiting wheel 9 moves on the ring track 4, it will drive the device plate 7 to move synchronously on the ring track 4.

[0029] To facilitate the support of the device plate 7 by the limiting wheel 9, the moving mechanism also includes a slider 10 connected to the side of the device plate 7 near the annular frame 3. The slider 10 contacts the inner wall of the annular frame 3. The slider 10 and the limiting wheel 9 are located at the inner ring of the annular frame 3 and the outer ring of the annular track 4, respectively. Therefore, the slider 10 and the limiting wheel 9 can connect the device plate 7 to the annular frame 3. Since the central axis of the annular frame 3 and the annular track 4 are collinear, when the device plate 7 moves, the slider 10 and the limiting wheel 9 can ensure that the device plate 7 travels along a specific trajectory of the annular track 4.

[0030] Furthermore, the driving component includes an internal gear ring 11 connected to the side of the annular track 4 away from the annular frame 3, a mounting plate 5 connected to the device plate 7, a drive motor 12 mounted on the mounting plate 5, and a gear 13 connected to the output end of the drive motor 12. The gear 13 meshes with the internal gear ring 11. The drive motor 12 is located on the side of the internal gear ring 11 away from the annular track 4. When the drive motor 12 drives the gear 13 to rotate, it will drive the device plate 7 to move through the mounting plate 5. Therefore, the central axis of the gear ring is collinear with the central axis of the annular track 4, so the limit wheel 9 will also move synchronously on the annular track 4.

[0031] Furthermore, since gear 13 is located inside the internal gear ring 11 and limit wheel 9 is located outside the annular track 4, gear 13 and limit wheel 9 can limit the movement of device plate 7 and support device plate 7.

[0032] Furthermore, to facilitate the use of the welding torch equipment 6, a lifting frame 14 is connected to the side of the device plate 7 away from the ring frame 3. The lifting frame 14 is provided with a sliding groove 15, and a connecting block 16 is slidably connected to the sliding groove 15. The welding torch equipment 6 is connected to the connecting block 16. By sliding the connecting block 16 in the sliding groove 15, the welding torch equipment 6 connected to the connecting block 16 can be moved, thereby adjusting the distance between the output end of the welding torch equipment 6 and the connection between the stirrup and the main reinforcement, so that the welding torch equipment 6 can more effectively perform welding operations at the connection between the stirrup and the main reinforcement.

[0033] The welding torch device 6 described above is an existing technical structure. Based on the device structure in this utility model, the corresponding structure and system parameters can be modified, which will not be described in detail.

[0034] To more effectively control the lifting and lowering movement of the connecting block 16 and the welding torch equipment 6, the lifting frame 14 is connected to the device with a certain distance between them, thus forming a lifting channel 17 between the lifting frame 14 and the device plate 7. The lifting frame 14 has an elongated groove 18, within which a connecting plate 19 is slidably connected. One end of the connecting plate 19 is connected to the connecting block 16. A fixing plate 20 is connected to the device plate 7, and a load-bearing plate 22 is connected to the fixing plate 20. A telescopic rod 23 is connected to the load-bearing plate 22, and the movable end of the telescopic rod 23 is connected to the connecting plate 19. The other end is connected to control the movement of the telescopic rod 23, which in turn drives the connecting plate 19 to move on the long groove 18, which in turn drives the connecting block 16 connected to the connecting plate 19 to move, which in turn drives the welding gun equipment 6 to move up and down, so that the output end of the welding gun equipment 6 can make better contact with the connection between the stirrups and the main reinforcement, thereby completing the welding operation. Secondly, when the inner diameter of the column formed by several main reinforcements is too large, the difference between the ring frame 3 and the main reinforcement can be made up by the lifting and moving of the welding gun equipment 6, so that the output end of the welding gun equipment 6 can make better contact with the connection between the stirrups and the main reinforcement.

[0035] In order to increase the adjustment position of the telescopic rod 23, several positioning holes 21 are provided on the fixed plate 20. The load-bearing plate 22 is connected to the positioning holes 21 by bolts. Thus, by installing the telescopic rod 23 at different positions, the movement range of the welding gun equipment 6 can be further adjusted so that its output end can better contact the connection between the stirrup and the main reinforcement.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
