Technical Field

[0001] The utility model belongs to the technical field of mining tools, and in particular relates to a welding slag collecting device used for mine shafts and pipelines. Background Art

[0002] During mine construction, shaft repairs and pipeline installations require welding operations. Whether it's torch cutting or welding, welding inevitably generates slag. Shafts, especially those in cable and ventilation shafts, often contain cables, and the resulting slag splashing poses a significant safety hazard. Fireproofing is often used to tightly cover working platforms within the shaft and wrap cables. While this effectively prevents fires caused by slag, gaps between platforms exist, and a small amount of slag can still fall from the shaft, posing a safety hazard. Utility Model Content

[0003] The utility model provides a welding slag collection device for mine shafts and pipelines, aiming to solve the problem that when welding operations are carried out in the shaft, flying welding slag may damage cables or even cause fires, posing certain safety hazards.

[0005] A welding slag collection device for mine shafts and pipelines includes an open slag collecting hopper, the bottom of which is connected to a drawer-shaped slag collecting trough. The slag collecting trough can be pulled along the bottom of the slag collecting hopper, and the slag falling into the slag collecting hopper falls along the hopper wall into the slag collecting trough. Handles are welded on the left and right sides of the upper edge of the slag collecting hopper.

[0006] The baffles on the left and right sides and the head end of the slag collecting hopper are fixed baffles, and the baffle at the tail end is a movable baffle. The movable baffle connects the left and right baffles through a hinge structure; a U-shaped notch is provided in the middle of the slag collecting trough near one end of the movable baffle, and the U-shaped notch is used to be stuck in the pipeline.

[0007] Furthermore, the movable baffle includes a left baffle and a right baffle, the left baffle is connected to the left hinge of the slag collecting hopper, and the right baffle is connected to the right hinge of the slag collecting hopper; the left baffle and the right baffle are connected by a pin structure, and when the pin is removed, the left baffle and the right baffle are opened; when the pin is installed, the left baffle and the right baffle are fixed.

[0008] Furthermore, the slag collecting hopper is formed by welding equilateral angle steels around the equilateral angle steels, and galvanized iron sheets are welded to the equilateral angle steels.

[0009] Furthermore, the bottom of the slag collecting hopper is open, and slide rails are connected to both sides of the bottom of the slag collecting hopper, and the slag collecting trough is connected to the slide rails.

[0010] The beneficial effects of the present invention are:

[0011] The utility model has a simple structure, novel design, practicality and reliability, overcomes the problem of welding slag splashing during welding operations during the repair and installation of the original wellbore, improves the safety of wellbore welding operations, and achieves good economic benefits; the utility model avoids welding slag splashing and the device is light, weighing only 10kg, and can be hung below the welding point for easy operation.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 3 As shown, a welding slag collection device for mine shafts and pipelines includes an open slag hopper 1 connected to a drawer-shaped slag collection trough 3 at its bottom. The bottom of the open slag hopper 1 is connected to slide rails 4 on both sides of the bottom of the slag hopper 1. The slag collection trough 3 is connected to the slide rails 4 and can be pulled along the bottom of the slag hopper 1. Slag falling into the slag hopper 1 falls along the hopper wall into the slag collection trough 3. Handles 2 are welded to the left and right sides of the slag hopper 1. The slag hopper 1 is formed by welding equal-leg angle steel on all sides, and galvanized iron sheets are welded to the equal-leg angle steel.

[0018] The baffles on the left and right sides and the head end of the slag collecting hopper 1 are fixed baffles, and the baffle at the tail end is a movable baffle. The movable baffles include a left baffle 5 and a right baffle 6. The left baffle 5 is connected to the left hinge of the slag collecting hopper 1, and the right baffle 6 is connected to the right hinge of the slag collecting hopper 1. The left baffle 5 and the right baffle 6 are connected by a latch structure. When the latch is removed, the left baffle 5 and the right baffle 6 are opened; when the latch is installed, the left baffle 5 and the right baffle 6 are fixed. The bottom of the left baffle 5 and the right baffle 6 is provided with a slot for passing through the slag collecting trough 3. A U-shaped notch 7 is provided in the middle of the slag collecting trough 3 near one end of the movable baffle. The U-shaped notch 7 is used to be inserted into the pipe. In order to improve the sealing effect, a circle of rubber sheet is sewn along the inner edge of the U-shaped notch 7. The U-shaped notch 7 can adapt to pipes of different sizes.

[0019] The method of using the utility model is as follows:

[0020] The device is divided into two parts, namely a trapezoidal slag collecting hopper 1 and a slag collecting trough 3. A hinge is installed on one side of the slag collecting hopper 1, which can be opened to wrap the pipeline. The U-shaped notch 7 in the slag collecting trough 3 can be used to fully wrap the pipeline. The steel wire rope is passed through the handles 2 on both sides, and the device can be hung under the welding point to complete the welding slag collection work.
