Description

Technical Field

[0001] The utility model relates to the technical field of steel cage welding, and more specifically to a road bridge steel cage welding device. Background Art

[0002] During the construction of large projects such as roads, bridges or high-rise buildings, it is usually necessary to carry out piling operations on the project foundation. After ensuring that the hole depth reaches the design standard, the pre-made steel cage is placed in the pile hole, and then extended into the pile hole through a guide tube for concrete pouring. The steel cage is connected into a whole by welding multiple steel bars to enhance the strength and stability of the structure. Most of the existing steel cage welding is done manually by using the positioning sleeve in the rolling welding machine to fix the main steel bars of the steel cage, and then the stirrups are manually wrapped around the multiple main steel bars to form a steel cage frame, which is convenient for manual welding.

[0003] When fixing the main steel bars, most of the existing steel cage welding devices use bolts to fix the main steel bars and positioning sleeves, which requires workers to use auxiliary tools to tighten the bolts one by one. It is impossible to fix multiple main steel bars at the same time. This fixing method wastes the labor of workers and a lot of time. Utility Model Content

The output end of the motor is fixedly connected to one end of the power rod passing through the fixed disk, and the motor is fixedly mounted on the fixed disk.

[0008] Furthermore, the extrusion assembly includes a connecting rod, a screw rod, a limit rod and a slider. The screw rod is arranged in the disc, and both ends of the screw rod are rotatably connected to the inner wall of the disc.

[0013] 2. According to the utility model, when the slider moves along the limit rod and approaches the connecting rod, the extrusion rod moves along the inclined surface of the slider, so that the limit rod drives the support rod, the fixed block, the support rod and the arc-shaped clamping block to move synchronously, so that the spring gradually rebounds. At this time, the arc-shaped clamping block no longer contacts the main steel bar and moves toward the slot. When the extrusion rod no longer contacts the inclined surface of the slider, the arc-shaped clamping block passes through the slot and is located outside the positioning sleeve. At this time, the spring no longer rebounds, and the fixation of multiple main steel bars can be released at the same time. There is no need for the staff to tighten the bolts one by one to release them, thereby improving the work efficiency of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 to Figure 7 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 7 The utility model is further described.

[0024] The utility model discloses a road bridge steel cage welding device, comprising two fixed plates 1, two slide rails 2 and a plurality of positioning sleeves 3, the two fixed plates 1 are provided with a support assembly 4 at the center, the plurality of positioning sleeves 3 are arranged on the two groups of support assemblies 4 in an annular and equidistant manner, the two fixed plates 1 are provided with a driving assembly 5 for driving the support assembly 4 to rotate, the surfaces of the plurality of positioning sleeves 3 are provided with notches 6, the two groups of support assemblies 4 are provided with a plurality of groups of limit assemblies 7 are arranged on the two groups of support assemblies 4 in an annular and equidistant manner, and are aligned with the corresponding notches 6, the middle of the plurality of limit assemblies 7 on the two support assemblies 4 are provided with an extrusion assembly 8 for making the plurality of limit assemblies 7 enter the corresponding notches 6, the two groups of extrusion assemblies 8 are connected to the corresponding support assemblies 4, one fixed plate 1 is fixedly installed on the two slide rails 2, and the other fixed plate 1 can move through the two slide rails 2.

[0025] When the movable plate 1 is moved away from the fixed movable plate 1, the staff will place the two ends of the main steel bar in the positioning sleeves 3 on the two fixed plates 1 respectively. When all the main steel bars are placed, the staff will rotate the extrusion assembly 8, and make the plurality of limit assemblies 7 pass through the slot 6 into the positioning sleeve 3 through the extrusion assembly 8 and contact the main steel bars. The main steel bars in the positioning sleeve 3 are squeezed and fixed by the plurality of limit assemblies 7, and multiple main steel bars can be fixed at the same time without manually tightening the bolts to fix the main steel bars. At this time, the driving assembly 5 drives the supporting assembly 4 to rotate, and drives the plurality of limit assemblies 7, the plurality of positioning sleeves 3 and the extrusion assembly 8 to rotate synchronously through the supporting assembly 4, so that the two The support assembly 4 on the fixed plate 1 rotates in the same direction. At this time, the fixed main steel bars are driven to rotate synchronously through a number of positioning sleeves 3. At this time, the staff wraps the stirrups around the frame formed by the main steel bars, and then the staff welds the contact parts of the stirrups and the main steel bars. When the welding is completed, the driving assembly 5 no longer drives the support assembly 4 to rotate. When the welded steel cage needs to be removed, the extrusion assembly 8 no longer squeezes the number of limit assemblies 7. At this time, the number of limit assemblies 7 no longer squeeze the main steel bars. At this time, the staff lifts the welded steel cage through the lifting equipment. At this time, the staff moves the movable fixed plate 1 away from the fixed fixed plate 1 through the slide rail 2. At this time, the staff takes out the two ends of the main steel bars from the positioning sleeve 3. The slide rail 2 is an electric slide rail 2 in the prior art and is not explained here.

[0026] Specifically, the support assembly 4 includes an annular opening 401, an annular ring 402, a cross 403, a disc 404 and an annular gear 405. The fixed disc 1 is hollow inside, the annular opening 401 is opened at the center of the fixed disc 1, the annular gear 405 is arranged in the fixed disc 1 and is rotatably connected with the fixed disc 1, the cross 403 is fixedly installed at the center of the annular gear 405, the disc 404 is fixedly installed at the center of the cross 403, the disc 404 is hollow inside, the annular ring 402 is fixedly installed on the cross 403, and a plurality of fixed discs 404 are provided. The positioning sleeves 3 are arranged in an annular shape and equidistantly on the annular ring 402, and are connected to the annular ring 402 by bolts. The driving assembly 5 includes a motor 501, a power rod 502 and a driving gear 503. The driving gear 503 is arranged in the fixed disk 1 and meshes with the annular gear 405. One end of the power rod 502 is fixedly connected to the driving gear 503, and the other end passes through the fixed disk 1 and is rotatably connected to the fixed disk 1. The output end of the motor 501 is fixedly connected to one end of the power rod 502 passing through the fixed disk 1, and the motor 501 is fixedly installed on the fixed disk 1.

[0027] In this embodiment, when the stirrups need to be wrapped around a frame formed by a plurality of main steel bars and the workers weld the contact parts between the stirrups and the main steel bars, the motor 501 is started, the motor 501 drives the power rod 502 to rotate, the power rod 502 drives the driving gear 503 to rotate, the driving gear 503 drives the annular gear 405 to rotate, the annular gear 405 drives the cross 403, the disc 404 and the annular ring 402 to rotate, and drives a plurality of positioning sleeves 3 to rotate through the annular ring 402, and the plurality of positioning sleeves 3 drive the fixed main steel bars to rotate synchronously.

[0028] Specifically, the extrusion assembly 8 includes a connecting rod 801, a screw rod 802, a limiting rod 803 and a slider 804. The screw rod 802 is arranged in the disk 404, and the two ends of the screw rod 802 are rotatably connected to the inner wall of the disk 404. The limiting rod 803 is arranged next to the screw rod 802, and the two ends of the limiting rod 803 are fixedly connected to the inner wall of the disk 404. The slider 804 is sleeved on the screw rod 802 and the limiting rod 803. The slider 804 is threadedly connected to the screw rod 802, and the slider 804 is slidably matched with the limiting rod 803. One end of the connecting rod 801 passes through the disk 404 and is fixedly connected to one end of the screw rod 802. The connecting rod 801 is rotatably connected to the disk 404, and the end of the slider 804 away from the connecting rod 801 is set as an inclined surface.

[0029] In this embodiment, when it is necessary to fix the two ends of the main steel bar, the staff rotates the connecting rod 801, and the connecting rod 801 drives the screw rod 802 to rotate. Because of the limitation of the limiting rod 803, the slider 804 moves along the limiting rod 803, so that the slider 804 is away from the connecting rod 801. When it is not necessary to fix the two ends of the main steel bar, the staff rotates the connecting rod 801 in the opposite direction, and the slider 804 gradually approaches the connecting rod 801 along the limiting rod 803.

[0030] Specifically, several limit assemblies 7 include a support rod 701, an arc-shaped block 702, a spring 703, a fixed block 704 and an extrusion rod 705. One end of the support rod 701 passes through the disc 404 and slides with the disc 404. The arc-shaped block 702 is fixedly connected to the other end of the support rod 701. The fixed block 704 is fixedly sleeved on the support rod 701. The extrusion rod 705 is fixedly connected to one end of the support rod 701 passing through the disc 404. The spring 703 is sleeved on the support rod 701. One end of the spring 703 is fixedly connected to the inner wall of the disc 404, and the other end is fixedly connected to the fixed block 704.

[0031] In this embodiment, when the slider 804 moves along the limiting rod 803 and away from the connecting rod 801, the inclined surface of the slider 804 contacts the extrusion rod 705 and squeezes the extrusion rod 705. At this time, the extrusion rod 705 moves along the inclined surface of the slider 804, so that the extrusion rod 705 drives the fixed block 704, the support rod 701 and the arc block 702 to move. At this time, the spring 703 is squeezed by the fixed block 704, and the arc block 702 passes through the notch 6 into the positioning sleeve 3, contacts the main steel bar, and squeezes the main steel bar, so that the main steel bar does not move in the positioning sleeve 3, and multiple main steel bars can be fixed at the same time. When welding is completed, the slider 804 moves along the limiting rod 803. When the positioning rod 803 moves close to the connecting rod 801, the extrusion rod 705 moves along the inclined surface of the slider 804, so that the limiting rod 803 drives the support rod 701, the fixing block 704, the support rod 701 and the arc-shaped block 702 to move synchronously, so that the spring 703 gradually rebounds. At this time, the arc-shaped block 702 no longer contacts the main steel bar and moves toward the slot 6. When the extrusion rod 705 no longer contacts the inclined surface of the slider 804, the arc-shaped block 702 passes through the slot 6 and is located outside the positioning sleeve 3. At this time, the spring 703 no longer rebounds, and the fixation of multiple main steel bars can be released at the same time. There is no need for the staff to tighten the bolts one by one to release them, thereby improving the work efficiency of the staff.

[0032] Specifically, a rotating disk 9 is fixedly mounted on the other end of the connecting rod 801 .

[0033] In this embodiment, the turntable 9 makes it more convenient for the staff to rotate the connecting rod 801.
