Abstract
An auxiliary protection device for gas cutting operation is arranged on a cutting torch gas pipe and comprises a protection cover, wherein the upper end of the protection cover is connected with the cutting torch gas pipe through a connecting sheet, a bolt and a nut; the protection casing is made of transparent materials and the lower end of the protection casing is lower than the cutting torch. The utility model provides a pair of supplementary protector during gas cutting operation falls to minimum with the spark that gas cutting operation produced to people's injury.
Description
Technical Field
The utility model relates to a gas cutting equipment, especially a supplementary protector during gas cutting operation.
Background
Gas cutting is a method of preheating the cutting part of a workpiece to a certain temperature by using the heat energy of flame generated by mixing and burning combustible gas and oxygen, then spraying high-speed cutting oxygen flow to ensure that metal is violently oxidized and releases heat, and blowing off the metal oxide in a molten state by using the cutting oxygen flow to realize cutting. In order to prevent the metal sparks from splashing and causing harm to the body, protective glasses and protective clothing are generally worn to protect the body, but when the gas cutting operation is carried out, a small part of the body is difficult to avoid being exposed in the air. The existing cutting guns are not provided with a protective device generally, so that the gas cutting operation still causes harm to the body.
The' 201510677853.3 patent discloses a shield for a cutting torch that is provided with a shield over the cutting tip, but that is located above the cutting tip and does not completely block splatter. In addition, the arrangement of a protective cover at the cutting tip still affects the observation of the operator.
Disclosure of Invention
The utility model aims to solve the technical problem that a supplementary protector during gas cutting operation is provided, the injury to people that can reduce the spark that the gas cutting operation produced is minimum.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
an auxiliary protection device for gas cutting operation is arranged on a cutting torch gas pipe and comprises a protection cover, wherein the upper end of the protection cover is connected with the cutting torch gas pipe through a connecting sheet, a bolt and a nut; the protection casing is made of transparent materials and the lower end of the protection casing is lower than the cutting torch.
The protection casing is platelike and the lower end is bent towards the cutting torch.
The protective cover comprises a lower plate and an upper plate, wherein slide rails are arranged above and below the lower plate, and the upper plate slides left and right along the lower plate; a plurality of jacks are formed in the slide rail along the length direction, elastic heads are arranged on the corresponding upper plates, and the elastic heads are connected with the jacks in an inserted mode.
The protective cover is a transparent PVC plate.
The utility model relates to an auxiliary protection device during gas cutting operation has following technological effect:
1) the device can move along with gas cutting operation, thereby achieving the purpose of dynamic protection.
2) The device can be detached at any time, is simple and convenient and quick to install, and saves time and labor.
3) The device adopts two kinds of protection casings, and the area is sheltered from in the adjustment of second kind protection casing can be according to actual demand, improves the flexibility ratio.
4) The protective cover is at a certain distance from the cutting nozzle, and the lower end of the protective cover is lower than the cutting nozzle, so that the protective cover plays a role in protection; meanwhile, the observation of operators is not influenced. Compared with an annular protective cover, the protective cover has the advantages that an operator can conveniently use the protective cover, and the protective area is larger.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is an installation schematic diagram of the present invention.
Fig. 2 is a front view (first type) of the present invention.
Fig. 3 is a schematic structural diagram (second type) of the present invention.
Fig. 4 is a partial sectional view of the elastic head of the present invention.
In the figure: the cutting torch comprises a cutting torch gas pipe 1, a protective cover 2, a connecting sheet 3, a bolt 4, a nut 5, a cutting nozzle 6, a lower plate 2-1, an upper plate 2-2, a sliding rail 2-3, a jack 2-4 and an elastic head 2-5.
Detailed Description
As shown in figures 1-2, the auxiliary protection device for gas cutting operation is arranged on a cutting torch gas pipe 1 and comprises a protection cover 2, two holes are arranged in the middle of a U-shaped connecting sheet 3, and the U-shaped connecting sheet 3 and the cutting torch gas pipe 1 are connected together through a bolt 4 and a nut 5. Two corresponding holes are respectively arranged on the two sides of the protective cover 2 and the U-shaped connecting piece 3, and the two ends of the U-shaped connecting piece 3 are fixed with the protective cover 2 through bolts 4 and nuts 5. The protection casing 2 is made for transparent PVC board and the lower extreme is less than cutting torch 6, like this under the prerequisite that does not influence the observation, can carry out the separation with the spark that the gas cutting operation produced, reduces the injury to the people.
The shield 2 here has two kinds, one of which is plate-shaped and the lower end is bent towards the cutting tip 6.
As shown in fig. 3-4, another structure is a drawing structure, which can adjust the shielding area according to the requirement. Specifically, the protective cover 2 comprises a lower plate 2-1 and an upper plate 2-2, wherein slide rails 2-3 are arranged above and below the lower plate 2-1, and the upper plate 2-2 slides left and right along the lower plate 2-1; a plurality of jacks 2-4 are arranged in the slide rail 2-3 along the length direction, elastic heads 2-5 are arranged on the corresponding upper plates 2-2, and the elastic heads 2-5 are inserted into the jacks 2-4. The upper end of the elastic head 2-5 extends out of the lower end of the upper plate 2-2 and is positioned in the sliding hole of the upper plate 2-2. The elastic head 2-5 comprises a rod body, a compression spring is sleeved in the rod body positioned in the sliding hole, and the lower end of the compression spring is limited by a limiting block on the rod body. When the rod body is pulled upwards, the compression spring is compressed, and the lower end of the rod body is separated from the jack 2-4, so that the upper plate 2-2 slides along the lower plate 2-1; when the rod body is loosened, the compression spring is reset, and the rod body enters the jacks 2-4. The overall length of the protective cover 2 can be adjusted by adjusting the relative positions of the lower plate 2-1 and the upper plate 2-2, so that the shielding area can be increased.
The working process and principle are as follows: the protective cover 2 is processed in advance in a plastic processing factory and is transported to a construction site. A proper position is selected on a cutting torch gas pipe 1 (a mixed gas pipe), and a U-shaped connecting sheet 3 is fixed on the cutting torch gas pipe through a bolt 4 and a nut 5. The protection cover 2 is arranged below the U-shaped connecting sheet 3, the U-shaped connecting sheet 3 and the protection cover 2 are punched at proper positions at two ends by an electric drill after the position is adjusted, and the protection cover 2 and the U-shaped connecting sheet 3 are fixed by a bolt 4 and a nut 5. After the gas cutting operation is finished, the protective cover 2 and the U-shaped connecting sheet 3 are sequentially taken down through the adjusting nut 5, and the operation is repeated when the next operation is finished.
