Description

Technical Field

[0001] This application relates to the field of welding carriage technology, and in particular to a welding carriage. Background Technology

[0002] Welding equipment is a key piece of equipment for joining metallic or non-metallic materials, and is widely used in construction, automotive, electronics, petrochemical, aerospace and other fields. The accompanying mobile trolley carries the welding machine, welding torch, wire feeder and gas cylinders, enabling flexible movement of the welding operation and allowing for semi-automatic or fully automatic operation.

[0003] During the welding process, the gas cylinder must work in conjunction with equipment such as the welding machine, wire feeder, and welding torch. To facilitate site relocation, the gas cylinder is usually installed on a mobile trolley along with the entire welding system.

[0004] However, existing mobile trolleys generally use a "fixed hole + single-diameter arc-shaped bracket" or "single-sided clamp" structure for securing gas cylinders. The bracket's curvature and hole positions are designed only for gas cylinders of specific sizes. When changing to gas cylinders of different diameters or heights, the entire bracket needs to be replaced or pads need to be added, resulting in poor adaptability, cumbersome replacement, and seriously affecting work efficiency and safety.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0041] This application discloses a welding trolley.

[0042] A welding trolley includes a trolley body 1, a vertical plate 2, a horizontal plate 3, and locking straps 4. The bottom of the trolley body 1 is equipped with universal casters to facilitate the movement of the trolley body 1. The vertical plate 2 is vertically fixed to the trolley body 1 by screws, and the horizontal plate 3 is horizontally fixed to the vertical plate 2 by screws. The vertical plate 2 and the horizontal plate 3 are arranged in an L-shape. The two ends of the locking straps 4 are detachably fixed to the vertical plate 2. Multiple locking straps 4 are provided along the height direction of the vertical plate 2 to accommodate gas cylinders 6 of different heights.

[0043] The vertical plate 2, the horizontal plate 3, and the locking strap 4 form a placement area. The size of the placement area can be adjusted to accommodate gas cylinders 6 of different heights and diameters.

[0044] Side plates 31 are fixedly installed on both sides of the horizontal plate 3 by screws. The side plates 31 and the horizontal plate 3 together form an upward-opening U-shape. When the gas cylinder 6 is placed on the horizontal plate 3, the side plates 31 on both sides of the horizontal plate 3 protect the gas cylinder 6.

[0045] A guide plate 32 is provided above the horizontal plate 3. The two sides of the guide plate 32 are rotatably connected to the side plate 31 by bolts. When the guide plate 32 rotates, it rotates around the side plate 31 of the horizontal plate 3 away from the vertical plate 2. When it is necessary to place the gas cylinder 6 on the horizontal plate 3, the guide plate 32 is rotated so that the side of the guide plate 32 away from the vertical plate 2 rotates downward to form an inclined plane. The guide plate 32 guides the gas cylinder 6 during the transportation process, improving the convenience of transporting the gas cylinder 6 to the horizontal plate 3.

[0046] The locking strap 4 includes a baffle 41, a locking strap 42, and a locking member 43. In this embodiment, the baffle 41 is concave on the side near the upright plate 2 to facilitate multi-point contact or even multi-line contact with the gas cylinder 6, thereby improving the stability of fixing the gas cylinder 6. A pair of locking straps 42 are provided. Each end of the baffle 41 is fixedly connected to a locking strap 42. One end of the locking strap 42 is fixedly connected to the end of the baffle 41, and the other end of the locking strap 42 is fixedly connected to a locking member 43. The locking member 43 is detachably fixedly connected to the upright plate 2.

[0047] The clamping area is formed between the upright plate 2, the locking band 42 and the baffle 41 to adjust the clamping range, so as to accommodate gas cylinders 6 of different diameters.

[0048] When securing the gas cylinder 6 with the locking strap 4, one end of the locking strap 4 is fixed to the upright plate 2, and the other end of the locking strap 4 is disconnected from the upright plate 2. After the gas cylinder 6 is placed on the horizontal plate 3, the end of the locking strap 4 that is not connected to the upright plate 2 is placed on the upright plate 2, and the locking strap 4 is pulled to adjust the range of the clamping area so that the gas cylinder 6 is pressed tightly on the upright plate 2. Then, the locking strap 4 is fixedly installed on the upright plate 2 to accommodate gas cylinders 6 of different diameters.

[0049] The upright plate 2 is symmetrically concave on the side near the gas cylinder 6. When the gas cylinder 6 and the upright plate 2 come into contact, the upright plate 2 and the gas cylinder 6 make multi-point contact, or even multi-line contact, which improves the stability of the gas cylinder 6. At the same time, after the locking strap 4 is pulled to press the gas cylinder 6 tightly against the upright plate 2, the symmetrical concave upright plate 2 positions the gas cylinder 6 at multiple points, further reducing the possibility of the gas cylinder 6 shifting after installation.

[0050] The upright plate 2 has protective grooves 21 on both sides in the height direction. The locking member 43 is placed in the protective groove 21. The locking member 43 is protected by the groove wall of the protective groove 21, reducing the possibility of the locking member 43 breaking off from the connection between the upright plate 2 due to accidental contact. In this application, the protective groove 21 is formed by bending the upright plate 2 on both sides in the height direction. At the same time as forming the protective groove 21, the side of the upright plate 2 close to the gas cylinder 6 is formed into a concave surface.

[0051] The locking component 43 includes a locking seat 431, a locking rod 432, and a locking nut 433. One end of the locking band 42 is detachably and fixedly installed on the locking seat 431. The locking rod 432 is fixedly installed on the locking seat 431. The locking nut 433 and the locking seat 431 are threadedly connected.

[0052] A guide groove 22 is provided through the wall of the protective groove 21 along the height direction of the vertical plate 2. The locking rod 432 is placed inside the guide groove 22 and slides in cooperation with the guide groove 22. The locking nut 433 is placed inside the protective groove 21.

[0053] When connecting the locking member 43 and the upright plate 2, the locking rod 432 is inserted into the guide groove 22. According to the required height position of the baffle 41, the locking rod 432 slides inside the guide groove 22. Then, the locking nut 433 is rotated to press the locking nut 433 against the inner wall of the protective groove 21, thereby facilitating the pressing of the gas cylinder 6 onto the upright plate 2.

[0054] An annular washer 434 is fitted on the locking rod 432. The annular washer 434 is placed inside the protective groove 21. The locking nut 433 presses the annular washer 434 against the inner wall of the locking groove. The large contact surface between the annular washer 434 and the inner wall of the protective groove 21 further improves the working stability of the locking nut 433.

[0055] When the locking band 42 is pulled, the locking rod 432 moves along the axis of the locking rod 432 inside the guide groove 22, thereby adjusting the range of the clamping area to accommodate different sizes of the gas cylinder 6.

[0056] To reduce the risk of the locking rod 432 rotating inside the guide groove 22 and causing the locking band 42 to twist, the locking seat 431 is provided with multiple locking rods 432. By simultaneously inserting multiple locking rods 432 on the locking seat 431 into the guide groove 22, the possibility of the locking rod 432 rotating is reduced. In this embodiment, each locking seat 431 is provided with two locking rods 432.

[0057] The locking seat 431 includes a pair of clamping plates 435. The two clamping plates 435 are detachably fixed together by multiple screws. The locking rod 432 is fixedly installed on the clamping plates 435. The end of the locking band 42 is placed between the two clamping plates 435. The two clamping plates 435 clamp and fix the locking band 42, which improves the convenience of fixing the locking band 42. At the same time, it is also convenient to replace the locking band 42. By replacing the locking band 42 with different lengths, the size of the clamping area can be changed to adapt to gas cylinders 6 with different diameters. Alternatively, the locking band 42 can be replaced periodically to ensure the quality of the locking band 42 and reduce the impact of the aging of the locking band 42 on fixing the gas cylinder 6.

[0058] The side of the clamping plate 435 and the contact surface of the locking band 42 are arc-shaped to reduce the possibility of damage to the locking band 42 due to excessive local stress.

[0059] The locking band 42 is detachably and fixedly installed on the plug block 5 near the baffle 41. The plug block 5 includes two plug plates 51, which are detachably and fixedly connected by screws. The locking band 42 is placed between the two plug plates 51, and the locking band 42 is clamped and fixed by the two plug plates 51.

[0060] The baffle 41 is provided with a plug groove 411, and the plug block 5 is interference-fitted with the plug groove 411. The interference fit between the plug block 5 and the plug groove 411 improves the ease of fixing the plug block 5. The plug block 5 can also be fixedly installed on the baffle 41 by screws.

[0061] The implementation principle of a welding trolley in this application embodiment is as follows: First, the trolley body 1 is moved to the working position by means of universal rollers. The guide plate 32 is rotated so that the side away from the vertical plate 2 forms an inclined surface. The gas cylinder 6 is pushed along the inclined surface of the guide plate 32 to the top of the horizontal plate 3. The side plates 31 on both sides of the horizontal plate 3 protect the gas cylinder 6. Then, according to the height of the gas cylinder 6, the locking member 43 is slid along the guide groove 22 in the protective groove 21 on both sides of the vertical plate 2 to a suitable position and fixed with the locking nut 433. Then, the locking bands 42 at both ends of the baffle 41 are wrapped around the gas cylinder 6 and fixed to the vertical plate 2 by the locking member 43. Pulling the locking band 42 makes the baffle 41 press the gas cylinder 6 and make symmetrical concave multi-point contact with the vertical plate 2 to complete the positioning. Finally, the guide plate 32 is reset to achieve stable transportation and fixing of the gas cylinder 6.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
