Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for welding operations, specifically relating to an integrated mobile platform for a carbon dioxide shielded welding machine. Background Technology

[0002] CO2 shielded welding machines are among the most widely used welding equipment in welding environments. They mainly consist of the welding machine, wire feeder, gas cylinder, and cables. Due to the limited welding radius of CO2 shielded welding machines, it is often necessary to move the machine to workstations that are far apart. Traditional methods either involve disassembling the welding machine into at least three parts and moving them one by one, or requiring multiple people to work together to move the machine without disconnecting the cables. Both methods are quite cumbersome, time-consuming, and labor-intensive.

[0003] To address this challenge, patent document CN2131200098U discloses a mobile protective trolley device for a carbon dioxide gas shielded welding machine. This device includes a vehicle frame and wheels. The vehicle frame is divided into a front equipment placement area and a rear gas cylinder placement area. A detachable central partition tube is located in the middle of the rear side of the gas cylinder placement area, and a detachable handrail tube is located at the upper rear side. When the central partition tube and handrail tube are removed, the gas cylinder can be horizontally pushed into the gas cylinder placement area simply by raising it above the height of the vehicle frame's bottom frame. While this patent document discloses a unified placement and transportation system for the welding machine equipment using a vehicle frame and wheels, this technical solution has the following problems in practical application:

[0004] 1. When placing gas cylinders in the cylinder placement area, it is necessary to remove the partition tube and the handrail tube, and then lift the gas cylinders above the height of the vehicle frame bottom frame before they can be pushed in horizontally. This makes the operation process cumbersome and lacks convenience and flexibility.

[0005] 2. Because the gas cylinder placement area and the equipment placement area adopt an integrated vehicle frame design, the spatial layout and functional connection between the two are not optimized. As a result, if it is necessary to replace the gas cylinder during the welding operation, additional equipment must be used to move the gas cylinder, which not only prolongs the time for gas cylinder replacement and movement, but also increases the labor intensity of the operators.

[0006] Therefore, it is necessary to design a new type of integrated mobile platform for carbon dioxide shielded welding machines to improve the ease of operation and flexibility of use, while effectively reducing the labor intensity of operators and optimizing the efficiency of cylinder replacement and cylinder movement. Utility Model Content

[0007] The purpose of this invention is to solve the above-mentioned problems in the prior art and to provide an integrated mobile platform for a carbon dioxide shielded welding machine. This invention effectively solves the technical problems of cumbersome carbon dioxide cylinder placement and low carbon dioxide cylinder replacement efficiency by using a detachable and fixed loading platform and a mobile trolley connection structure, as well as a combination structure of the mobile trolley using a main support wheel frame and an auxiliary support wheel frame, thus significantly improving welding operation efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An integrated mobile platform for a carbon dioxide shielded welding machine includes a loading platform and a mobile trolley for loading carbon dioxide cylinders. The mobile trolley is detachably fixed to the loading platform. The mobile trolley includes a main support wheel frame and an auxiliary support wheel frame. The auxiliary support wheel frame is foldably mounted on the main support wheel frame. The auxiliary support wheel frame has a folded state and an unfolded state that can be switched under force. In the unfolded state, the auxiliary support wheel frame cooperates with the main support wheel frame to form a movable structure. In the folded state, the auxiliary support wheel frame folds and closes to the main support wheel frame.

[0010] The main support wheel frame includes two support wheels, two trolley handles, and a loading frame. The two support wheels are symmetrically fixed at the bottom of the loading frame, and the two trolley handles are symmetrically fixed at the top of the loading frame. The rear end of the loading frame is rotatably connected to the auxiliary support wheel frame, and the front end of the loading frame is detachably fixed to the loading platform.

[0011] The loading frame includes a base frame, a left side frame, a right side frame, and a rear end frame that are fixedly connected to each other. The loading frame has an opening at the top and an opening at the front. The loading frame forms an enclosed cavity with the side of the loading platform through the base frame, left side frame, right side frame, and rear end frame.

[0012] The auxiliary support wheel frame includes a folding control frame and a support frame. The folding control frame is hinged to the rear end frame and the support frame respectively. Two trolley casters are symmetrically installed at the lower end of the support frame, and the upper end of the support frame is hinged to the rear end frame.

[0013] The support frame includes two support legs and a middle crossbar. The two support legs are symmetrically fixed at both ends of the middle crossbar. The upper ends of the two support legs are respectively hinged to the rear end frame, and the lower ends of the two support legs are respectively connected to two trolley casters. The folding control frame includes a rotating connector and a folding control rod. The folding control rod is located between the two support legs and above the middle crossbar. The folding control rod is hinged to the rear end frame. One end of the rotating connector is hinged to the folding control rod, and the other end is hinged to the middle of the middle crossbar. The support frame unfolds and folds on the main support wheel frame through the cooperation of the folding control rod and the rotating connector.

[0014] The rotating connector includes two connecting blocks, two connecting pins, and a connecting seat. The connecting seat is fixed on the middle crossbar and is positioned opposite to the folding control rod. The two connecting pins are respectively movably inserted through and laterally positioned on the connecting seat and the folding control rod. The two connecting blocks are symmetrically positioned on the left and right sides of the connecting seat. The left connecting block is fixedly connected to the left end of the two connecting pins, and the right connecting block is fixedly connected to the right end of the two connecting pins.

[0015] In the unfolded state, the support leg rotates and unfolds on the rear frame via the folding control frame. The folding control rod can abut against the connecting seat. The unfolded support leg and the lower trolley caster together with the support wheel form a triangular structure for supporting the movement of the trolley. In the folded state, the support leg and trolley caster are located above the support wheel.

[0016] The loading platform is fixed with pins and hooks on its sides. The pins are located above the hooks, and the moving trolley is detachably and fixedly connected to the loading platform through the hooks and pins.

[0017] The loading platform is equipped with a platform handle at the top and platform casters at the bottom.

[0018] After the mobile trolley is fixed on the loading platform, the bottom surface of the support wheels of the mobile trolley is higher than the bottom surface of the platform casters of the loading platform.

[0019] The advantages of using this utility model are:

[0020] The integrated mobile platform for carbon dioxide shielded welding machines of this utility model firstly optimizes the two work processes of welding operation and carbon dioxide cylinder replacement through the detachable and fixed connection design of the mobile trolley and the loading platform, making the operation process more coherent and simple, and with high flexibility in site adaptability.

[0021] Secondly, the mobile trolley's movable structure, formed by the cooperation of the main support wheel frame and the auxiliary support wheel frame, optimizes the spatial layout and functional connection between the mobile trolley and the loading platform. During welding operations, if a gas cylinder needs to be replaced, it can be used independently to replace the carbon dioxide gas cylinder. Operators no longer need to use additional equipment to move the gas cylinder, which not only significantly shortens the time for replacing and moving the carbon dioxide gas cylinder, but also ensures the smoothness and continuity of the welding operation and the gas cylinder replacement process, effectively reducing the labor intensity of operators and significantly improving work efficiency.

[0022] Third, by folding the auxiliary support wheel frame closer to the main support wheel frame in the folded state, the space occupied by the integrated mobile platform at the welding operation site is optimized and reduced.

[0023] In summary, this utility model, through the detachable and fixed connection design of the mobile trolley and the loading platform, and the combination structure of the main support wheel frame and the auxiliary support wheel frame of the mobile trolley, forms an integrated mobile platform for CO2 shielded welding machines. Compared with the prior art represented by the announcement number "CN2131200098U", it effectively solves the technical problems of cumbersome gas cylinder placement and low gas cylinder replacement efficiency, which is conducive to improving the ease of operation and flexibility of welding operations, effectively reducing the labor intensity of operators, and optimizing the efficiency of CO2 gas cylinder replacement and movement.

[0024] 2. In this utility model, the main support wheel frame adopts a structural design of two support wheels, two trolley handles and a loading frame, which ensures the ease of operation of the mobile trolley when changing and moving carbon dioxide cylinders, thereby improving the practicality of the mobile trolley.

[0025] 3. In this utility model, by employing a loading frame composed of a base frame, a left side frame, a right side frame, and a rear end frame that are fixedly connected to each other, and by designing openings at the top and front end of the loading frame, the convenience for operators to easily place or remove carbon dioxide cylinders when the mobile trolley is separated from the loading platform is improved. Simultaneously, when the mobile trolley is fixed to the loading platform, the base frame, left side frame, right side frame, and rear end frame of the loading frame form an enclosed cavity with the side of the loading platform, improving the safety and reliability of the fixed placement of the carbon dioxide cylinders.

[0026] 4. In this utility model, by adopting an auxiliary support wheel frame structure composed of a folding control frame and a support frame, the flexibility of the mobile trolley in use and the space utilization rate during storage are improved.

[0027] 5. In this utility model, the structural layout of the support legs and the folding control rod enables convenient operation of the auxiliary support wheel frame. The design of the folding control rod makes it easy to unfold and fold the support frame on the main support wheel frame, while further ensuring the stability of the mobile trolley and the efficiency of space utilization, thus improving the overall practicality and convenience of the integrated mobile platform.

[0028] 6. In this utility model, the rotating connector is designed to include two connecting blocks, two connecting pins, and a connecting seat. The connecting seat is fixed on the middle crossbar, and the connecting pins movably pass through the connecting seat and the folding control rod. The connecting blocks are symmetrically arranged on both sides of the connecting seat and fixedly connected to the connecting pins. This not only ensures the stability of the connection between the folding control rod and the support frame through the rotating connector, but also ensures the reliability of the folding control rod in controlling the unfolding and folding of the support frame through the rotating connector.

[0029] 7. In this utility model, the design of the auxiliary support wheel frame forming a triangular structure in the unfolded state not only enhances the stability of the mobile trolley when it is disassembled and placed after being removed from the loading platform, but also ensures the safety and reliability of the carbon dioxide cylinder replacement and movement operations. In addition, in the folded state, the support legs and the trolley's universal wheels can be compactly located at the rear end of the support wheels, achieving compactness and consistency in folding and storage, while improving the portability of the mobile trolley.

[0030] 8. In this utility model, the design of hooks and pins fixed on the side of the mobile platform realizes a stable and convenient detachable fixed connection between the mobile trolley and the loading platform. This not only improves the flexibility and efficiency of the integrated mobile platform and ensures that operators can quickly and easily disassemble and assemble it when needed, but also enhances the stability and safety of the mobile trolley and the loading platform in the connected state, as well as the safety and reliability of the gas cylinder fixing.

[0031] 9. In this utility model, the design of a platform handle fixed to the top of the loading platform and a platform caster wheel fixed to the bottom further improves the convenience of using the integrated mobile platform.

[0032] 10. In this utility model, the bottom surface of the support wheel of the mobile trolley is higher than the bottom surface of the platform caster of the loading platform, which ensures the smooth movement of the entire integrated mobile platform. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0039] Example 1

[0040] An integrated mobile platform for a carbon dioxide shielded welding machine, such as Figure 1-4 As shown, it includes a loading platform 9 and a mobile trolley 1 for loading carbon dioxide cylinders. The loading platform 9 is used to load welding machines, cables and wire feeders. Depending on the different sizes and models of the welding machines, cables and wire feeders, the loading platform 9 can be flexibly configured to include multiple loading levels such as upper, middle and lower layers.

[0041] The mobile trolley 1 is detachably fixed to the loading platform 9, so as to... Figure 1 Taking the direction shown as an example, the mobile trolley 1 is detachably fixed to the left side of the loading platform 9; the mobile trolley 1 includes a main support wheel frame 15 and an auxiliary support wheel frame 2. The auxiliary support wheel frame 2 is foldably mounted on the main support wheel frame 15. The auxiliary support wheel frame 2 has a folded state and an unfolded state that can be switched by force. In the unfolded state, the auxiliary support wheel frame 2 cooperates with the main support wheel frame 15 to form a movable structure. In the folded state, the auxiliary support wheel frame 2 folds and moves closer to the main support wheel frame 15.

[0042] Specifically, such as Figure 1-2 As shown, when the mobile trolley 1 is fixed to the left side of the loading platform 9, it is in an upright position. The mobile trolley 1 and the loading platform 9 form an integrated mobile platform suitable for on-site welding operations. At this time, the auxiliary support wheel frame 2 is folded and close to the main support wheel frame 15 to reduce the space occupied by the welding operation. When the mobile trolley 1 is disassembled from the loading platform 9, the top of the mobile trolley 1 is tilted backward, as shown. Figure 3As shown, at this time, the auxiliary support wheel frame 2 unfolds on the main support wheel frame 15. The movable structure formed by the cooperation of the auxiliary support wheel frame 2 and the main support wheel frame 15 allows the mobile trolley 1 to be used independently for replacing and moving carbon dioxide cylinders. In actual cylinder replacement operations, only one operator is needed to complete the task. By applying appropriate force to the mobile trolley 1 and using the support wheels 5 as flexible pivot points, the operator can easily and quickly fix or disassemble the top of the mobile trolley 1 to one side of the loading platform 9. This design not only simplifies the operation process but also significantly improves work efficiency, ensuring the smoothness and continuity of welding operations and cylinder replacement processes.

[0043] This utility model, through the design of the mobile trolley 1 and the loading platform 9, and the combination structure of the main support wheel frame 15 and the auxiliary support wheel frame 2 of the mobile trolley 1, forms an integrated mobile platform for carbon dioxide shielded welding machines. This is beneficial to improving the ease of operation and flexibility of welding operations, effectively reducing the labor intensity of operators, and optimizing the efficiency of carbon dioxide cylinder replacement and movement.

[0044] Example 2

[0045] Based on the structure of Example 1, this example optimizes the cooperative structure of the main support wheel frame 15 and the auxiliary support wheel frame 2.

[0046] like Figure 1-3 As shown, the main support wheel frame 15 includes two support wheels 5, two trolley handles 11, and a loading frame 200, so as to... Figure 2 Taking the direction shown as an example, two support wheels 5 are symmetrically fixed to the bottom of the loading frame 200, and two trolley handles 11 are symmetrically fixed to the top of the loading frame 200. The rear end of the loading frame 200 is rotatably connected to the auxiliary support wheel frame 2, and the front end of the loading frame 200 is detachably fixed to the loading platform 9.

[0047] The loading frame 200 includes a base frame 201, a left side frame 202, a right side frame 203, and a rear end frame 204 that are fixedly connected to each other. The loading frame 200 has a top opening and a front opening. After the mobile trolley 1 is separated from the loading platform, the opening design allows operators to easily place or remove carbon dioxide cylinders. When the mobile trolley 1 is fixed to the loading platform, the loading frame 200, through the base frame 201, left side frame 202, right side frame 203, and rear end frame 204, forms an enclosed cavity with the side of the loading platform 9, ensuring the safety and reliability of the fixed placement of the carbon dioxide cylinders.

[0048] Continue to refer to Figure 1-3The auxiliary support wheel frame 2 includes a folding control frame 4 and a support frame 12. The folding control frame 4 is hinged to the rear end frame 204 and the support frame 12 respectively. Two trolley casters 3 are symmetrically installed at the lower end of the support frame 12, and the upper end of the support frame 12 is hinged to the rear end frame 204.

[0049] Specifically, the support frame 12 includes two support legs 120 and a central crossbar 121, so as to... Figure 2-3 Taking the direction shown as an example, two support legs 120 are symmetrically fixed to the left and right ends of the middle crossbar 121. The upper ends of the two support legs 120 are respectively hinged to the rear end frame 204 through the first pin 205. The lower ends of the two support legs 120 are respectively connected to two trolley casters 3. The folding control frame 4 includes a rotating connector 13 and a folding control rod 400. The folding control rod 400 is located between the two support legs 120 and above the middle crossbar 121. The folding control rod 400 is hinged to the rear end frame 204. One end of the rotating connector 13 is hinged to the folding control rod 400, and the other end is hinged to the middle of the middle crossbar 121. In order to optimize the force-saving effect and torque distribution, the rotating connector 13 is hinged at the hinge point of the folding control rod 400, preferably in the middle of the folding control rod 400 but more inclined to the side closer to the connecting end 402. The support frame 12 unfolds and folds on the main support wheel frame 15 through the cooperation of the folding control lever 400 and the rotating connector 13. Specifically, the folding control lever 400 has a gripping part 401 and a connecting end 402. The connecting end 402 of the folding control lever 400 is hinged to the rear end frame 204 through the second pin 206. In the unfolded state, the gripping part 401 of the folding control lever 400 extends beyond the middle crossbar 121. In the folded state, the folding control lever 400 folds and closes to the rear end frame 204.

[0050] Furthermore, such as Figure 2 As shown, the rotating connector 13 includes two connecting blocks 130, two connecting pins 131, and a connecting seat 132. The connecting seat 132 is fixed on the middle crossbar 121 and is arranged opposite to the folding control rod 400. The two connecting pins 131 are respectively movably inserted through and laterally arranged on the connecting seat 132 and the folding control rod 400, serving the functions of connection and rotation.

[0051] Two connecting blocks 130 are symmetrically arranged on the left and right sides of the connecting seat 132. The left connecting block 130 is fixedly connected to the left end of each of the two connecting pins 131, and the right connecting block 130 is fixedly connected to the right end of each of the two connecting pins 131. This design not only ensures the structural stability of the rotating connecting piece 13, but also allows the folding control rod 400 to rotate smoothly around the connecting pins 131, thereby controlling the switching between the folding and unfolding states of the auxiliary support wheel frame 2.

[0052] like Figure 3As shown, in the unfolded state, the support leg 120 rotates and unfolds on the rear frame 204 via the folding control frame 4. When the support leg 120 unfolds to its limit angle with the bottom of the mobile trolley 1, the folding control rod 400 abuts against the connecting seat 132, preventing the support leg 120 from continuing to rotate behind the main support wheel frame 1. At this time, the unfolded support leg 120 and the trolley caster 3 and support wheel 5 at the lower end of the support leg 1 form a triangular structure to support the mobile trolley 1 for movement, so that the mobile trolley 1 can change and transport carbon dioxide cylinders; while in the folded state, the auxiliary support wheel frame 2, as shown... Figure 2 As shown, the support leg 120 and the trolley caster 3 are located above the support wheel 5, thereby achieving compactness and consistency in folding and storage.

[0053] Example 3

[0054] Based on Embodiments 1 and 2, this embodiment further clarifies the specific structural features of the connectors used for the detachable fixed connection between the loading platform 9 and the mobile trolley 1.

[0055] like Figure 1 , Figure 4 As shown, the loading platform 9 is fixed with a pin lock 6 and a hook 7 on its sides. The pin lock 6 is located above the hook 7. The mobile trolley 1 is detachably and fixedly connected to the loading platform 9 through the hook 7 and the pin lock 6. During the process of fixing the mobile trolley 1 to the loading platform 9, the hook 7 first engages with the base frame 201 of the loading frame 200 in the mobile trolley 1, and then the pin lock 6 is used to lock it, thereby ensuring that the mobile trolley 1 can be firmly connected to the loading platform 9, providing stable support for subsequent welding operations.

[0056] In addition, two limiting members 17 are symmetrically fixed to the side of the loading platform 9, so as to... Figure 4 Taking the direction shown as an example, the two limiting members 17 are located on the outside of the two hooks 7 respectively. When the mobile trolley 1 is fixed to the side of the loading platform 9 by the hooks 7, the two limiting members 17 can prevent the mobile trolley 1 from tilting to the sides, thereby improving the stability and reliability of the entire structure.

[0057] In some embodiments, the connection between the hook 7 and the mobile trolley 1 can also be replaced by a snap-fit ​​connection structure.

[0058] like Figure 1 As shown, a platform handle 10 is fixed to the top of the loading platform 9, and a platform caster wheel 8 is fixed to the bottom.

[0059] After the mobile trolley 1 is fixed on the loading platform 9, when the mobile trolley 1 is placed vertically, the bottom surface of the support wheel 5 of the mobile trolley 1 is higher than the bottom surface of the platform caster 8 of the loading platform 9. This makes it easier to push the loading platform 9 and prevents the mobile trolley 1 and its support wheel 5 from becoming obstacles to the movement of the loading platform 9, thus ensuring smooth movement.

[0060] The above description is only a specific embodiment of the present utility model. Any feature disclosed in this specification may be replaced by other equivalent or similar features unless otherwise specified. All features or steps in all methods or processes disclosed may be combined in any way except for mutually exclusive features and / or steps.
