Description

Technical Field

[0001] This utility model belongs to the field of steel pipe welding technology, and in particular relates to a mobile operation shed for long-distance buried steel pipe welding. Background Technology

[0002] In the welding of long-distance buried steel pipelines outdoors, workers are greatly affected by weather and environmental factors, especially during the snowy and rainy seasons. Rainwater and snowmelt can slide down the surface of the steel column or fall on the welding position, which is detrimental to the welding quality. When the welding environment is limited, welding efficiency is easily reduced, which restricts the progress of on-site construction. In addition, since the welding of long-distance buried steel pipelines involves a large number of pipes and welds, the workload is large. If existing work sheds are used for construction, they need to be moved repeatedly, which seriously affects the work efficiency and increases the work risk. Finally, since the work will be carried out outdoors, the work sheds may need to be moved or operated on different trench geological conditions or slopes. Existing work sheds or platforms are difficult to meet various working conditions, creating resistance to the welding operation and affecting the welding process. Utility Model Content

[0030] like Figures 1 to 4 As shown, this utility model includes a work shed body and a plurality of driving wheels 1 all disposed at the bottom of the work shed body. A motor 15 is disposed inside the work shed body, and the driving wheels 1 are mounted on the output shaft 16 of the motor 15.

[0031] The main body of the work shed includes a vertically arranged work shed frame 2 and a roof 3 set on top of the work shed frame 2. The work shed frame 2 and the roof 3 are welded together. The work shed frame 2 and the roof 3 enclose a steel pipe work area.

[0032] The work shed frame 2 includes two vertically arranged and symmetrically arranged frame sidewalls. The frame sidewalls are arranged along the extension direction of the steel pipe. Two frame end faces are vertically arranged between the two frame sidewalls. The two frame end faces are symmetrically arranged at both ends of the frame sidewalls. The frame end faces and the frame sidewalls are welded together. Color steel tiles are laid on the outer side of the frame sidewalls and the outer side of the frame end faces.

[0033] A ventilation fan 13 is installed on the ceiling 3;

[0034] The interior of the work shed body is symmetrically provided with two equipment platforms 14, which are horizontally arranged on the side wall of the frame.

[0035] The end of the output shaft 16 extends to the outside of the work shed body, and the traveling wheel 1 is installed on the outside of the work shed body; a chain drive assembly is provided between the traveling wheels 1 on the same side of one of the frame sidewalls; a locking rod 18 is provided between the chain drive assembly and the frame sidewall.

[0036] In practical use, by installing travel wheels 1 at the bottom of the work shed body, the work shed can be moved as a whole. This movement simultaneously moves the equipment placed inside the work shed, overcoming the shortcomings of conventional welding work sheds such as low efficiency and inconvenience. While ensuring the working environment, it can guarantee normal pipeline welding conditions in winter and rainy seasons, accelerating construction efficiency. Furthermore, the travel wheels 1 are installed at the bottom of the work shed body, and a chain drive assembly is installed between the travel wheels 1 on the same side of one of the frame sidewalls, which can drive the travel wheels 1 on the same side to rotate synchronously, facilitating the movement or operation of this mobile work shed under different trench geological conditions. Finally, a locking rod 18 is installed between a gear 17 and a sidewall vertical rod 4. When stability is required on a slope, the locking rod 18 is inserted between the gear 17 and the sidewall vertical rod 4, fixing the gear 17 to the work shed body and forming a lock, ensuring the mobile work shed is stable on the slope construction section, facilitating welding operations without affecting them.

[0037] In particular, when workers use this mobile work shed for long-distance pipeline circumferential welding, it ensures that the humidity and temperature of the welding environment meet the requirements and is unaffected by external winter rain and strong winds. Furthermore, the work shed can move the welding equipment along with it, eliminating the need for equipment assistance in the movement of conventional work sheds. This significantly accelerates construction efficiency and further improves welding quality in heavy-duty long-distance pipeline welding operations, resulting in high efficiency and saving time and labor.

[0038] It should be noted that the driving wheels 1 can be DN300 rubber wheels; the equipment platform 14 can meet the needs of pipe welding equipment and gas cylinder storage. The ventilation fan 13 installed on the roof 3 can ensure air circulation inside the steel pipe working area. In order to ensure the normal use of the access door 9, when laying the corrugated steel sheets on the access door 9, they need to be laid separately from the corrugated steel sheets laid on the outer side of the frame end face so that they are not affected during use; at the same time, in order to ensure the normal entry and exit of steel pipes, corrugated steel sheets do not need to be laid in the pipe placement area; the areas on the working shed body that need to be laid with corrugated steel sheets are all fixed with screws and rods. The contact surface between the pipe protection frame 10 and the pipe is wrapped with a rubber pad to avoid direct contact between the pipe protection frame 10 and the pipe, which would cause damage to the external anti-corrosion of the pipe.

[0039] like Figure 2As shown, in this embodiment, the frame sidewall includes a plurality of vertically arranged sidewall vertical bars 4 and a plurality of horizontally arranged sidewall horizontal bars 5. The sidewall vertical bars 4 and sidewall horizontal bars 5 are arranged in a cross shape and are welded together.

[0040] like Figure 3 As shown, in this embodiment, the frame end face includes two vertically arranged access doors 9 at the ends of the frame side walls. The access doors 9 are located at the bottom of the outermost side wall vertical rod 4, and the access doors 9 and the side wall vertical rod 4 are connected by hinges. A pipe protection frame 10 is connected between the tops of the two access doors 9, and the area below the pipe protection frame 10 is the pipe placement area. An end face vertical rod 11 is vertically arranged at the top of the pipe protection frame 10, and the top of the end face vertical rod 11 is connected to the ceiling horizontal rod 6. End face horizontal rods 12 are symmetrically arranged on both sides of the pipe protection frame 10, and the end face horizontal rods 12 are horizontally connected between the pipe protection frame 10 and the side wall vertical rod 4.

[0041] like Figure 3 As shown, in this embodiment, the pipe protection frame 10 has an arc-shaped structure, and a rubber pad is provided on the pipe protection frame 10. The rubber pad is arranged along the circumferential direction of the pipe protection frame 10 and is arranged in the pipe placement area.

[0042] like Figure 2 and 3 As shown, in this embodiment, the canopy 3 includes multiple canopy units, each disposed between the tops of the two frame sidewalls. The multiple canopy units are arranged along the extension direction of the frame sidewalls, and the tops of the multiple canopy units are covered with corrugated steel sheets. Each canopy unit includes a horizontal canopy crossbar 6 disposed between the tops of the two frame sidewalls and a herringbone support bar 7 disposed above the horizontal canopy crossbar 6. A vertical canopy bar 8 is disposed between the horizontal canopy crossbar 6 and the herringbone support bar 7. The horizontal canopy crossbar 6, the herringbone support bar 7 and the vertical canopy bar 8 are welded together.

[0043] like Figure 4 As shown, in this embodiment, the chain drive assembly includes a gear 17 coaxially arranged with the traveling wheel 1 and a chain 19 connected to the outside of the gear 17. The gear 17 is arranged on the outside of the work shed body.

[0044] like Figure 4 As shown, in this embodiment, the locking rod 18 is arranged between the gear 17 and the side wall of the frame. The locking rod 18 passes through the gear 17 and a side wall vertical rod 4 of the side wall of the frame. Both the gear 17 and the side wall vertical rod 4 of the side wall of the frame have through holes for the locking rod 18 to pass through.

[0045] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
