Technical Field
[0001] This utility model relates to the field of crane technology, specifically to a rotatable crane support structure welding device. Background Technology
[0002] A crane is a mechanical device used to lift and lower heavy objects. It is widely used in industries such as construction, manufacturing, and ports. Depending on its structure and purpose, there are many types of cranes, such as bridge cranes, gantry cranes, tower cranes, and mobile cranes. In the process of manufacturing and maintaining cranes, welding of various crane components is a very important step to ensure the strength and safety of the structure.
[0003] Patent CN221313000U discloses a welding device for crane accessories, relating to the technical field of crane manufacturing. This invention includes a base support plate, a fixed plate, a pushing assembly, and a clamping groove. The fixed plate is fixed to one edge of the top of the base support plate. The pushing assembly is laterally and movably connected within the fixed plate. The pushing assembly includes a rotating screw, a positioning plate, and a turntable. The rotating screw is threadedly connected within the fixed plate. One end of the rotating screw is rotatably connected to the positioning plate, and the end of the positioning plate away from the rotating screw is rotatably connected to the turntable. The end of the turntable away from the rotating screw is fixed with a clamping groove. This invention, by setting up a base support plate, a fixed plate, a pushing assembly, and a clamping groove, solves the problems of insufficient applicability of current crane component welding devices to welding combinations of different components, and the cumbersome welding procedures for the same batch of components.
[0004] Based on existing solutions and practical applications, current crane support welding devices still have some problems. For example, when welding crane components, the components are supported and welded. Because the existing support frames are fixed, frequent adjustments and welding from different directions are required, which reduces the continuity and integrity of the welding and thus affects the welding quality. Utility Model Content
[0005] The purpose of this invention is to provide a rotatable crane support structure welding device to solve the problem mentioned in the background art that the current support frames are all fixed, which requires operators to frequently adjust and weld from different directions when welding components, resulting in a decrease in the continuity and completeness of the welding.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotatable crane support structure welding device, comprising:
[0007] The base has a support plate fixedly installed on its top. A connecting plate is slidably connected to the outer side of the support plate, and the height of the support plate is smaller than the height of the connecting plate. A lifting assembly for height adjustment is provided on the base plate. A rotating sleeve is rotatably connected to the upper end of the connecting plate, and a rotating rod is rotatably connected inside the rotating sleeve. The right end of the rotating rod is threaded. A gear is fixedly installed on the left end of the rotating sleeve, and a first hinge lug is fixedly installed on the right end of the rotating sleeve. A limiting pin is inserted into the rotating sleeve, and the pin passes through the rotating sleeve. A direction adjustment assembly is provided on the left end of the connecting plate, and a clamping assembly is provided on the rotating rod.
[0008] Preferably, the lifting assembly includes a bidirectional threaded rod, an internal threaded sleeve, a motor, and a connecting rod. The bidirectional threaded rod is rotatably connected to the left end inside the base, and the front and rear ends of the bidirectional threaded rod are threadedly connected to the internal threaded sleeve. The motor is fixedly installed at the left end of the rear end of the base, and the output end of the motor is connected to the rear end of the bidirectional threaded rod. The connecting rod is rotatably connected to the internal threaded sleeve.
[0009] Preferably, the connecting rod is inclined and rotatably connected to the side wall of the connecting plate, and the internal threaded sleeve block drives the connecting plate through the connecting rod to form a lifting structure.
[0010] Preferably, the direction adjustment assembly includes a rack and an electric push rod, and the rack is slidably connected to the upper end of the left end of the connecting plate, and the rack meshes with a gear. The electric push rod is fixedly installed on the left side wall of the connecting plate, and the output end of the electric push rod is connected to the rack.
[0011] Preferably, the clamping assembly includes a second hinge lug, a hinge rod, and a fixed clamping plate, and the right end of the rotating rod is connected to the second hinge lug by a thread, and both the upper and lower ends of the second hinge lug are rotatably connected to hinge rods, and a fixed clamping plate is installed on the body of the hinge rod.
[0012] Preferably, the hinge rod is arranged in an "X" shaped structure, with the left end of the hinge rod rotatably connected to the first hinge lug, the right end of the hinge rod slidably connected to the fixed clamping plate, and the left end of the hinge rod rotatably connected to the fixed clamping plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This rotatable crane support structure welding device allows the welding components to be welded at multiple angles by rotating the fixed clamping plates. The welding angle and position can be quickly adjusted by rotation. Then, by moving the fixed clamping plates closer to or further apart from each other, the components can be firmly fixed to prevent displacement during the welding process, thereby improving the continuity, accuracy and consistency of the welding. At the same time, by adjusting the height of the fixed clamping plates, adjustments can be made according to the actual situation, allowing the operator to find the best welding position and obtain a more comfortable position for welding.
[0014] 1. The device is equipped with a rotating sleeve, a rotating rod, a gear, a rack, an electric push rod, a fixing pin, and a fixing clamp. The output end of the electric push rod drives the rack to slide on the left end of the connecting plate. The rack and gear mesh with each other, and the rotating sleeve and rotating rod are connected by the fixing pin. When the electric push rod extends or retracts, the rack drives the rotating sleeve to rotate through the gear, which in turn drives the fixing clamp to rotate, thereby rotating the parts to be welded. By rotating the fixing clamp, the parts to be welded can be welded at multiple angles, and the welding angle and position can be quickly adjusted by rotation, thereby improving the continuity of welding.
[0015] 2. The device is equipped with a rotating sleeve, a rotating rod, a fixing pin, a first hinge ear, a second hinge ear, a hinge rod, and a fixing clamp. By pulling out the fixing pin, the fixing between the rotating sleeve and the rotating rod can be released. Then, by fixing the rotating sleeve and rotating the rotating rod, the right end of the rotating rod is connected to the second hinge ear by a thread. The hinge rod is set in an "X" shape, with the left end of the hinge rod rotatably connected to the first hinge ear and the right end of the hinge rod rotatably connected to the second hinge ear. The right end of the hinge rod is also slidably connected to the fixing clamp. When the rotating rod is rotated, the second hinge ear causes the hinge rod to extend and retract. The extension and retraction of the hinge rod causes the fixing clamps to move closer or further apart, thereby fixing the parts to be welded. The fixing clamp can firmly fix the parts, preventing displacement during welding, and also allowing the operator to quickly complete positioning and fixing, thereby improving the accuracy and consistency of welding.
[0016] 3. The system includes a base, support plate, connecting plate, bidirectional threaded rod, internal threaded sleeve block, motor, and connecting rod. The motor's output drives the bidirectional threaded rod to rotate inside the base. The connecting rod, in an inclined state, rotates and connects with the internal threaded sleeve block and the side wall of the connecting plate. The rotation of the bidirectional threaded rod causes the internal threaded sleeve block to slide in the opposite direction. This sliding motion of the internal threaded sleeve block, via the connecting rod, creates a lifting structure on the connecting plate, allowing the connecting plate to slide outside the support plate. This adjusts the welding height. By adjusting the height of the fixed clamping plate, adjustments can be made according to actual conditions, allowing operators to find the optimal welding position and achieve a more comfortable welding experience.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-7 This utility model provides a technical solution: a rotatable crane support structure welding device, comprising: a base 1, a support plate 2, a connecting plate 3, a bidirectional threaded rod 4, an internal threaded sleeve block 5, a motor 6, a connecting rod 7, a rotating sleeve rod 8, a rotating rod 9, a gear 10, a rack 11, an electric push rod 12, a fixing pin 13, a first hinge ear 14, a second hinge ear 15, a hinge rod 16, and a fixing clamp 17.
[0027] Example 1; please refer to the attached document. Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 and attached Figure 7 As shown, when welding crane components, the components are first erected and fixed. Since the fixing pin 13 passes through the rotating sleeve rod 8, the rotating sleeve rod 8 and the rotating rod 9 are fixed together. Further, the fixing pin 13 is pulled out, thus releasing the fixation between the rotating sleeve rod 8 and the rotating rod 9. Then, the operator holds the handle on the body of the rotating sleeve rod 8 to fix it, preventing the rotating sleeve rod 8 from rotating along with the rotating rod 9. Since the rotation of the rotating rod 9 is connected to the rotation of the rotating sleeve rod 8, the operator can further rotate the rotating rod 9. Because the right end of the rotating rod 9 is threaded, and the body of the rotating rod 9 is connected to the second hinge ear 15 via the thread, and the first hinge ear 14 is also fixedly installed on the body of the rotating sleeve rod 8, the hinge rod 16 is arranged in an "X" shape and is rotatably connected to the second hinge... The left end of the hinge rod 16 is rotatably connected to the first hinge ear 14 on the ear 15. A fixed clamping plate 17 is installed on the body of the hinge rod 16, and the hinge rod 16 is rotatably connected to the fixed clamping plate 17. The left end of the hinge rod 16 is slidably connected to the fixed clamping plate 17. When the rotating rod 9 is rotated, the second hinge ear 15 slides on the body of the rotating rod 9, and the second hinge ear 15 causes the hinge rod 16 to contract or extend, thereby causing the hinge rod 16 to move closer or further away from the fixed clamping plate 17. The fixed clamping plate 17 fixes the component and supports the component. After the component is fixed, the fixing pin 13 is inserted again through the rotating sleeve rod 8, and the rotating sleeve rod 8 and the rotating rod 9 are fixed together again. The fixed clamping plate 17 supports and fixes the component, which can prevent displacement during the welding process.
[0028] After the components are fixed, the height of the components can be adjusted according to the operator's welding habits or actual conditions. First, the motor 6 is started, and the output end of the motor 6 drives the connecting rod 7 to rotate inside the double-threaded rod 4. The rotation of the double-threaded rod 4 drives the internal threaded sleeve 5 to slide. Then, the connecting rod 7 is rotatably connected to the top of the internal threaded sleeve 5, and the connecting rod 7 is rotatably connected to the side wall of the connecting plate 3 in an inclined state. When the double-threaded rod 4 rotates, it drives the internal threaded sleeve 5 to slide in the opposite direction, and the internal threaded sleeve 5 drives the connecting rod 7 to slide on the top of the base 1. The connecting rod 7 drives the connecting plate 3 to form a lifting structure. Then, the connecting plate 3 slides outside the support plate 2, and the height of the support plate 2 is smaller than the height of the connecting plate 3, so that the connecting plate 3 slides outside the support plate 2 and the height of the fixed components on the fixed clamp 17 is adjusted, so that it can be adjusted according to the actual situation and ensure that the operator finds the best welding position.
[0029] Example 2; please refer to the appendix. Figure 1 Appendix Figure 2 and attached Figure 3 As shown, after the component is placed and its height is adjusted, the electric push rod 12 can be extended and retracted. Since the output end of the electric push rod 12 is connected to the rack 11, the extension and retraction of the electric push rod 12 can drive the rack 11 to slide back and forth. Then, the rack 11 meshes with the gear 10 on the left end of the rotating sleeve rod 8. Thus, the sliding of the rack 11 can drive the rotating sleeve rod 8 to rotate through the gear 10, and the rotating sleeve rod 8 rotates on the plate of the connecting plate 3. Since the rotating sleeve rod 8 and the rotating rod 9 are fixed together by the fixing pin 13, the rotation of the rotating sleeve rod 8 can synchronously drive the fixed clamping plate 17 to rotate, and rotate the component. Thus, by rotating the fixed clamping plate 17, the component can be adjusted to a suitable welding angle and position, thereby improving the continuity of welding.
