Description

Technical Field

[0001] The utility model relates to the technical field of steel bar welding devices, in particular to a steel bar welding device for sunken tube rock embedded piles. Background Art

[0002] Pipe-sinking and rock-embedded cast-in-place piles are a construction technology that involves sinking a steel pipe with a flap-type pile tip or a prefabricated reinforced concrete pile tip into the soil, and then pouring concrete to form a pile body while the steel pipe is pulled out. During the construction of pipe-sinking and rock-embedded cast-in-place piles, the steel cage is an important load-bearing structure, and each steel bar needs to be connected by welding to ensure the structural strength and stability of the pile body. Therefore, the steel bar welding device plays a vital role in this process. However, in the prior art, the steel bar welding device generally fixes the steel bar by a simple limiting device. During the welding process, the steel bar is likely to be unstable and cause uneven welding, which will have a certain impact on the normal use of the steel bar.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN219131253U proposes a steel bar welding device, which drives a threaded rod to rotate through a motor, so that the threaded rod drives a cross plate to move, so that the cross plate drives a pressure plate downward with the assistance of multiple structures, so that the pressure plate contacts the surface of the steel bar, and then through the cooperation of the pressure plate and the groove, the positions of the two steel bars are restricted to ensure the stability of the steel bars during welding.

[0004] However, although the above-mentioned steel bar welding device can move the cross plate by rotating the threaded rod, so that the cross plate drives the pressure plate to move downward and clamp and fix the steel bar, the steel bar welding device can only clamp and fix a single steel bar, and cannot clamp and fix a steel cage with a large number of steel bars, thereby resulting in a problem of reduced application scope of the device. Therefore, the utility model provides a steel bar welding device for immersed tube rock-embedded piles to meet the demand. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a steel bar welding device for sunken tube rock-embedded piles.

[0006] The technical problem to be solved by the utility model is to provide a steel bar welding device for rock-embedded piles to solve the problem that the existing steel bar welding device can only clamp and fix a single steel bar but cannot clamp and fix a steel cage with a large number of steel bars, thereby reducing the application scope of the device.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A steel bar welding device for sunken tube rock-embedded piles, comprising:

[0009] A connecting plate, with two sets of supporting frames arranged opposite to each other on both sides, and the tops of the two sets of supporting frames are fixedly connected with a fixing plate;

[0010] At least two clamping plates are symmetrically arranged and are rotatably arranged between the two fixed plates through a rotating shaft. The two clamping plates are fixedly connected with mutually meshing half gears. A driving gear is sleeved on the rotating shaft of one of the clamping plates, and a rack is slidably connected to the fixed plate. A driving mechanism for driving the rack to slide is provided on the fixed plate.

[0011] Preferably, the driving mechanism comprises:

[0012] a threaded rod rotatably disposed within the fixed plate;

[0013] A worm wheel is sleeved and fixedly connected to the threaded rod, and a worm screw meshing with the worm wheel is rotatably connected to the fixing plate, and the worm screw extends to the outside of the fixing plate;

[0014] A slider is fixedly connected to the rack, and one end of the slider facing away from the rack is sleeved and threadedly connected to the threaded rod.

[0015] Preferably, the fixed plate is provided with a sliding groove for the sliding block to slide and a movable groove for the worm gear to rotate.

[0016] Preferably, the clamping plate has a clamping groove that fits with the outer wall of the steel cage.

[0017] Preferably, a rubber pad is fixedly connected in the clamping groove.

[0018] Preferably, the clamping plate has a limiting end at one end away from the half gear, and the limiting end is an arc-shaped structure opposite to the clamping groove.

[0019] Compared with the prior art, the utility model has at least the following beneficial effects:

[0020] In the above scheme, a driving mechanism is provided to drive the driving gear to rotate, thereby realizing the rotation of the rotating shaft and the clamping plate, which is convenient for clamping and fixing multiple steel bars on the steel cage, facilitates subsequent welding, and improves the application scope of the device.

[0021] In the above scheme, by setting the clamping groove, rubber pad and limit end, the clamping groove can make the clamping plate more stable when clamping the steel bar. At the same time, the rubber pad can avoid damage to the clamping plate and the steel bar. The setting of the limit end can avoid dislocation of the steel bar during the clamping process.

[0031] Specifically, there is a gap between the two groups of support frames 2, the clamping plate 6 is located between the gaps, and the welding point 4 of the steel cage 3 is also located within the gap between the two groups of support frames 2. At the same time, there needs to be enough support at the bottom of the steel cage 3 to fix the steel bars, and the steel bars to be welded are located at the top of the steel cage 3. During welding, the steel cage 3 is placed on the two groups of support frames 2, and then the driving mechanism 9 drives the rack 8 to move, the rack 8 drives the driving gear 7 to rotate, and the driving gear 7 drives the rotating shaft 5 to rotate, so that the rotating shaft 5 drives one of the clamping plates 6 to rotate. At this time, under the action of the half gear 14, the other clamping plate 6 rotates relatively, thereby clamping the steel bars. The overall operation is simple, which is convenient for clamping and fixing multiple steel bars on the steel cage 3, and is convenient for later welding, thereby improving the scope of application of the device and solving the problem that the existing steel bar welding device can only clamp and fix a single steel bar, but cannot clamp and fix a steel cage with more steel bars, thereby reducing the scope of application of the device.

[0032] It should be noted that, in the present embodiment, the steel bars on the steel cage 3 can be welded by external welding equipment, such as manual welding, automatic welding by a robotic arm, etc. The present embodiment aims to improve the stability of the steel bar welding on the steel cage 3, and is not only capable of clamping and fixing a single steel bar, thereby improving the scope of application of the device; further, in the present embodiment, the number of rotating shafts 5 and clamping plates 6 can be adjusted according to the number of steel bars in the steel cage 3, and is not restricted here.

[0033] like Figure 1 and Figure 5 As shown, in the present embodiment, the driving mechanism 9 comprises a threaded rod 91, which is rotatably arranged in the fixed plate 10, a worm wheel 94, which is sleeved and fixedly connected to the threaded rod 91, a worm 93 meshing with the worm wheel 94 is rotatably connected to the fixed plate 10, and the worm 93 extends to the outside of the fixed plate 10, a slider 92, which is fixedly connected to the rack 8, and the end of the slider 92 facing away from the rack 8 is sleeved and threadedly connected to the threaded rod 91, and the fixed plate 10 is provided with a slide groove 13 for sliding the slider 92 and a movable groove 15 for rotating the worm wheel 94. Specifically, the worm wheel 94 is driven to rotate by the worm 93, the worm wheel 94 drives the threaded rod 91 to rotate, and the threaded rod 91 drives the slider 92 to slide along the slide groove 13, so that the slider 92 drives the rack 8 to move.

Specifically, the clamping groove 12 can make the clamping plate 6 more stable when clamping the steel bar, and the rubber pad 11 can be used to avoid damage to the clamping plate 6 and the steel bar, and the setting of the limiting end 16 can avoid dislocation of the steel bar during the clamping process.

[0035] Working principle:

[0036] During welding, the steel cage 3 is placed on two groups of support frames 2, and then the worm 93 drives the worm wheel 94 to rotate, the worm wheel 94 drives the threaded rod 91 to rotate, and the threaded rod 91 drives the slider 92 to slide along the slide groove 13, so that the slider 92 drives the rack 8 to move, the rack 8 drives the driving gear 7 to rotate, and the driving gear 7 drives the rotating shaft 5 to rotate, so that the rotating shaft 5 drives one of the clamping plates 6 to rotate, and at this time, under the action of the half gear 14, the other clamping plate 6 rotates relatively, so as to clamp the steel bars. The overall operation is simple, which is convenient for clamping and fixing multiple steel bars on the steel cage 3, and is convenient for later welding, thereby improving the application range of the device and solving the problem that the existing steel bar welding device can only clamp and fix a single steel bar, but cannot clamp and fix a steel cage with more steel bars, thereby reducing the application range of the device.
