Description

Technical Field

[0001] This utility model relates to the field of welding sheds, specifically to a mobile welding shed for steel beam assembly yards. Background Technology

[0002] After the steel beams are assembled in the secondary assembly area, they need to be welded. During the welding operation, welding fume collectors and hood-type dust collection devices must be used to effectively treat the polluting fumes. In order to collect welding fumes more effectively and ensure that normal construction is not affected by rain, a movable welding shed needs to be set up.

[0003] While existing portable welding sheds can provide shelter from rain and ensure construction can proceed normally, they are prone to accumulating shallow puddles after heavy rains due to the grid-like frame structure and tarpaulin covering most of these sheds. Given the sheds' height, it's difficult for personnel to promptly remove this water, leading to deformation of the tarpaulin covering.

[0004] Therefore, a mobile welding shed for steel beam assembly yards is needed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0037] Please see Figures 1-5 This utility model provides a mobile welding shed for steel beam assembly, comprising: frame assembly 1, connecting rod 7, frame assembly 2 8, inclined plate 9, tarpaulin 2, covering plate 3, walking mechanism 4, water absorption mechanism 5, and extrusion mechanism 6.

[0038] The frame assembly 1 is configured as multiple sets, and the multiple sets of frame assembly 1 are connected by multiple sets of connecting rods 7. Two sets of frame assembly 2 8 are provided below the multiple sets of frame assembly 1. The bottom end of each set of frame assembly 2 8 is connected to the walking mechanism 4 through a base plate. Two sets of inclined plates 9 are provided on one set of frame assembly 1.

[0039] In addition to the two sets of inclined plates 9, two sets of tarpaulins 2 are installed on the frame group 1. The two sets of tarpaulins 2 are connected by connecting columns 12.

[0040] Each of the frame groups 2 8 is equipped with a cover plate 3, which is divided into short plates installed at the front and rear ends of each frame group 2 8 and long plates installed at the side ends of each frame group 2 8.

[0041] Each set of inclined plates 9 is provided with the extrusion mechanism 6, and each set of tarpaulin 2 is provided with the water absorption mechanism 5 above it. The water absorption mechanism 5 is connected between the connecting column 12 and the long plate.

[0042] In a preferred embodiment, the frame assembly 1 of this invention is a triangular stable frame with multiple horizontal and vertical connecting components inside. Multiple frame assemblies 1 are combined via connecting rods 7 to form the top frame of the welding shed. Frame assembly 2 8 is a three-dimensional frame with external cladding plates 3 for reinforcement. The two sets of frame assemblies 2 8 form the supporting frame of the welding shed. The combination of the top frame and the supporting frame forms the main structure of the welding shed. This main structure has enhanced load-bearing capacity and stability, and can completely resist the damage to its stability caused by strong winds, ensuring the safety of workers inside the shed and guaranteeing the normal progress of construction.

[0043] In this embodiment, a tarpaulin 2 is added to the main structure of the welding shed to provide roof protection, enabling normal operation in rainy weather. The tarpaulin 2 can be made of shading material, effectively reducing the temperature inside the shed and decreasing energy consumption. The tarpaulin 2 can also be made of recyclable materials, reducing environmental pollution and protecting the environment.

[0044] It is important to note that the main structure of the welding shed is constructed entirely of lightweight materials, and all components are assembled using easily detachable connections. This significantly reduces the time required for assembling and disassembling the welding shed, improves overall work efficiency, and allows more time for subsequent welding work.

[0045] Furthermore, multiple main shielding curtains 10 are installed on a group of frame assemblies 1 that are away from and close to the extrusion mechanism 6, and a secondary shielding curtain 11 is installed below each group of cover plates 3, the secondary shielding curtains 11 enclosing the walking mechanism 4.

[0046] In this embodiment, multiple sets of main shielding curtains 10 are provided at both the front and rear ends of the welding shed, which can ensure the normal movement of the welding shed without being restricted by the position of the steel beams. The main shielding curtains 10 can also seal the space inside the shed to prevent welding fumes from leaking out.

[0047] The welding shed is moved by the walking mechanism 4. The walking mechanism 4 can be one of the commonly available walking components, which will not be described in detail here.

[0048] The secondary shielding curtain 11 below the cover plate 3 can effectively reduce the impact of welding fumes inside the shed on the walking mechanism 4, and avoid problems such as failure of the walking mechanism 4 due to excessive welding fumes inside the shed.

[0049] Furthermore, a slide rail 121 is provided on the connecting column 12.

[0050] Furthermore, the water absorption mechanism 5 includes: a housing 51, a control component 52, a water absorption component 53, a power component 54, and a slide rail 55;

[0051] One end of the housing 51 is slidably connected to the slide rail 121 via the slide rail 55, and the other end is slidably connected to the cover plate 3 via the power assembly 54;

[0052] The control component 52 is installed inside the housing 51. Multiple sliding mouth groups are equidistantly opened at the lower end of the housing 51. Each sliding mouth group consists of three sliding mouths. The water absorption component 53 is installed at the position of each sliding mouth group.

[0053] In this embodiment, please refer to Figure 1 , Figure 2 As shown, after heavy rain, several low-lying areas of water accumulate on the tarpaulin 2 on the roof frame of the welded shed. These low-lying areas often appear in places such as... Figure 2 The rectangular section shown at point A. This invention features a water-absorbing mechanism 5 that can reciprocate along the tarpaulin 2. During this movement, it can promptly absorb water from low-lying areas, preventing excessive water accumulation and deformation of the tarpaulin 2. The specific water-absorbing operation will be described in detail below.

[0054] Furthermore, the power assembly 54 includes a roller assembly 541 and a drive assembly 542. The cover plate 3 has a wheel rail. One end of the roller assembly 541 is rotatably connected to the wheel rail, and the other end is rotatably connected to the wheel frame. The end of the wheel frame away from the roller assembly 541 is connected to the housing 51. The drive assembly 542 is provided on the roller assembly 541.

[0055] In this embodiment, the water-absorbing mechanism 5 can reciprocate along the tarpaulin 2 with the aid of the power assembly 54. The drive group 542 in the power assembly 54 is one of the common existing drive components (not described in detail here), which can drive the roller group 541 to roll, thereby realizing the reciprocating movement of the water-absorbing mechanism 5 along the tarpaulin 2.

[0056] Furthermore, the control component 52 includes: a rotating wheel 521, a rotating belt 522, a control protrusion 523, and a power unit 524;

[0057] The power unit 524 is fixedly installed on the outside of the housing 51, and the output end of the power unit 524 rotatably passes through the housing 51 and extends into its interior;

[0058] A horizontal shaft is rotatably connected to the end of the housing 51 away from the power unit 524. The horizontal shaft and the output end of the power unit 524 are both fixedly connected to the rotating wheel 521. The outer wall of the two sets of rotating wheels 521 is sleeved with the rotating belt 522. Multiple sets of control protrusions 523 are equidistantly arranged on the side of the rotating belt 522 away from the rotating wheel 521.

[0059] Furthermore, each of the water-absorbing components 53 consists of three sets of lifting members, each set of lifting members including: a base frame 531, a sliding plate 532, a spring 533, a sliding rod 534, a contact upper end 535, and a lifting lower end 536;

[0060] The sliding plate 532 is slidably disposed within the base frame 531;

[0061] The sliding rod 534 has a contact upper end 535 at one end inside the housing 51 and a lifting lower end 536 at the other end outside the housing 51. The rod body of the sliding rod 534 slides through the top of the base frame 531, the sliding plate 532 and the sliding opening on the housing 51 in sequence.

[0062] The spring 533 is connected between the slide plate 532 and the interior of the housing 51 and is sleeved on the outside of the slide rod 534.

[0063] Furthermore, cotton blocks 13 are provided on the lower end 536 of the three sets of lifting members located within the same water-absorbing assembly 53.

[0064] It should be noted that the positions of each water-absorbing component 53 are located near the rectangular areas on the tarpaulin 2 where low-lying water accumulation is likely to occur (such as...). Figure 2 , Figure 3 (Corresponding to point A in the middle)

[0065] For a preferred embodiment, please refer to Figure 3 , Figure 4 As shown, during the reciprocating movement of the housing 51 driven by the power component 54, the power machine 524 starts to work, the power machine 524 drives the rotating wheel 521 to rotate, and the rotating belt 522 rotates synchronously. Each control protrusion 523 on the rotating belt 522 will pass through each water absorption component 53 in sequence.

[0066] When the control protrusion 523 passes one of the water-absorbing components 53, it will, by virtue of its own curved contour, abut against the upper contact ends 535 of the three slide rods 534 in sequence, thereby pushing the three slide rods 534 outward from the housing 51, and the springs 533 on each slide rod 534 will begin to compress. When the upper contact ends 535 of each slide rod 534 disengage from the control protrusion 523, they will reset due to the elastic force of the springs 533, awaiting the lifting operation of the next control protrusion 523.

[0067] The three sliding rods 534 lift in sequence, causing the cotton block 13 to bulge from one end to the other. During this bulging process, the cotton block 13 absorbs water from low-lying areas. This effectively addresses water accumulation on the tarpaulin 2 and prevents excessive water accumulation from deforming the tarpaulin 2.

[0068] Furthermore, the extrusion mechanism 6 includes: an extrusion shell 61, an extrusion cavity 62, a fixing block 63, a sliding column 64, an extrusion spring 65, and an extrusion plate 66;

[0069] The extrusion shell 61 is mounted on the inclined plate 9 and has a plurality of extrusion cavities 62 equidistantly arranged thereon. Each extrusion cavity 62 is provided with a fixing block 63. The fixing block 63 has a sliding cavity, and the sliding column 64 is slidably connected in the sliding cavity.

[0070] The end of the sliding column 64 away from the sliding cavity is fixedly connected to the extrusion plate 66, the extrusion spring 65 is connected between the extrusion plate 66 and the fixing block 63, and the extrusion spring 65 is sleeved on the outside of the sliding column 64.

[0071] It should be noted that the multiple sets of cotton blocks 13 correspond to the multiple sets of squeezing plates 66. After the water absorption mechanism 5 reciprocates several times, the cotton blocks 13 on it reach a fully saturated state. At this time, when the water absorption mechanism 5 moves to a position close to the squeezing mechanism 6, it will not move back, but will continue to move towards the squeezing mechanism 6 to perform the drainage operation.

[0072] For a preferred embodiment, please refer to Figure 5 As shown, when the cotton block 13 is driven by the water absorption mechanism 5 to contact the squeezing plate 66, the squeezing plate 66 will compress the squeezing spring 65 and move towards the squeezing chamber 62. During this process, the cotton block 13 is squeezed, changing it from a fully saturated state to a partially saturated state. After squeezing is completed, the water absorption mechanism 5 continues to reciprocate to absorb water, and under the action of the squeezing spring 65, the squeezing plate 66 returns to its initial position.

[0073] It should be noted that to determine when the absorbent mechanism 5 stops its reciprocating movement for drainage, an additional monitoring element can be added to monitor the state of the cotton block 13, thereby controlling the power component 54 to stop its reciprocating movement in a timely manner to initiate the drainage operation. Alternatively, the power component 54 can be controlled by an operator to stop its reciprocating movement for drainage. The operator does not need to monitor the state of the cotton block 13; they only need to control the power component 54 after the absorbent mechanism 5 has reciprocated a few times (three or four times).

[0074] Furthermore, a flow channel 91 is provided on the inclined plate 9.

[0075] In this embodiment, the position of the flow channel 91 corresponds to the position of the cotton block 13 during the drainage operation. When the water absorption mechanism 5 performs the drainage operation, the water squeezed out from the cotton block 13 can flow away through the flow channel 91.

[0076] In practice, multiple frame groups 1 are combined via connecting rods 7 to form the top frame of the welding shed, and two frame groups 8 form the supporting frame of the welding shed. The top frame and the supporting frame are combined to form the main structure of the welding shed. A tarpaulin 2 is added to the main structure of the welding shed to provide roof protection, allowing for normal operation in rainy weather. Multiple main shielding curtains 10 are installed at the front and rear sections of the welding shed, ensuring normal movement of the welding shed without being restricted by the position of the steel beams. The movement of the welding shed relies on the walking mechanism 4, and the main shielding curtains 10 can also seal the interior space to prevent welding fumes from leaking out. After heavy rain, the water absorption mechanism 5 can promptly absorb and treat the water accumulated in low-lying areas, and the squeezing mechanism 6 can drain the cotton blocks 13 in the water absorption mechanism 5.

[0077] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
