Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude steel structure welding, in particular to a high-altitude steel structure welding dust suppression device. Background Art

[0002] As a basic process in modern manufacturing industry, welding technology is gradually developing from traditional single connection technology to hot forming technology integrating electrical, mechanical, material and computer disciplines, playing an irreplaceable role in engineering machinery, water conservancy and hydropower, shipbuilding heavy industry, transportation, military equipment and other fields. In the welding process, there are arc radiation, high temperature, noise, welding fume and toxic gases, which not only pollute the environment but also harm the health of employees. Among them, for arc, high temperature, noise, etc., masks and earplugs can be used as effective protective equipment, but as a first-level carcinogen, welding fume, there is currently no better protection and control means.

[0003] Corresponding to the high-altitude steel structure welding operation, there is a pipeline welding protection and exhaust gas collection device with the existing publication number CN219186195U, which includes a welding smoke collection device and a fixing device. When in use, the fixing device is fixed to the pipeline that needs to be operated through the rectangular hole on the arc-shaped steel plate by a binding strap. The left and right angles and the up and down swing amplitude of the welding smoke collection device are adjusted by the combination of the column, the top rod and the clip. The base, the column, the clip and the adjusting screw jointly adjust the height of the welding smoke collection device. After the welding smoke collection device is placed in a suitable position, the cylinder is pulled down, the light belt switch and the fan switch are turned on, and the welding operation is carried out, so that the smoke and dust in the welding process can be collected; the existing technology has the following disadvantages when used: the cylinder can only be set in a single direction and cannot meet the multi-directional welding smoke collection requirements; and when performing high-altitude welding operations, the welding slag will fall downward due to gravity, and the existing technology cannot realize the collection of welding slag. Therefore, the dust suppression effect of the existing technology in high-altitude steel structure welding operations is not ideal. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a high-altitude steel structure welding dust suppression device which is easy to install and operate and can ensure that the structure can be used for a long time.

[0007] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0020] Combined with Figure 1-4 The purpose of further describing the present application in detail is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0021] Embodiment 1: This embodiment of the present application discloses a high-altitude steel structure welding dust suppression device, such as Figure 1 , including several welding slag collecting mechanisms, which are arranged in a ring shape and sleeved on the lower side of the steel structure where welding is to be carried out; in this embodiment, since the steel structure with construction is a square steel column, four welding slag collecting mechanisms are arranged on the lower side of the waiting welding machine position, which are arranged on the front, rear, left and right sides of the steel structure respectively; each welding slag collecting mechanism includes a collecting trough 1, which is an inverted quadrangular pyramid structure, and the upper opening of the collecting trough 1 is rectangular and is provided with an assembly groove, in which a filter plate 2 is installed, and the filter plate 2 is provided with a plurality of filter holes; a connecting pipe 7 is provided at the lower opening of the collecting trough 1 and is connected to a smoke collecting mechanism through the connecting pipe 7; a clamping mechanism is provided on the side of the collecting trough 1 close to the steel structure, and the welding slag collecting mechanism is locked and fixed to the steel structure through the clamping mechanism.

[0022] Embodiment 2, on the basis of embodiment 1, discloses the specific structure of the clamping mechanism, the clamping mechanism comprises a vertically arranged clamping plate 3, the clamping plate 3 is threadedly connected with an adjusting screw 6 and is locked and fixed by a locking nut, the adjusting screw 6 is horizontally arranged and one end of the adjusting screw 6 abuts against the outer wall of the steel structure; adjacent clamping plates 3 are connected by latch hinges 8, a number of connected clamping plates 3 are annularly sleeved on the outer side of the steel structure, and are locked and fixed with the steel structure by the coordinated action of a number of adjusting screws 6; in this embodiment, four clamping plates 3 are arranged in a square frame, and the four corners are connected by latch hinges 8; Figure 4 The latch hinge 8 includes a first hinge, a second hinge and a pin rod. The first hinge and the second hinge are welded and fixed on adjacent clamping plates 3 and connected by the pin rod. When the welding height needs to be changed, the locking nut is loosened and the adjusting screw 6 is adjusted so that its end is not tightly against the steel structure. The square frame surrounded by the four clamping plates 3 is slid up and down. After adjusting to the appropriate position, the adjusting screw 6 is rotated again so that the ends of the four adjusting screws 6 are all in contact with the steel structure, thereby completing the fixation of the device. In addition, by adjusting the adjusting screw 6, the device can also be applied to steel structure columns of different sizes.

[0023] Embodiment three, further, in order to prevent welding slag from falling from the gap between the clamping plate 3 and the steel structure, a lap plate 4 is hinged on the upper edge of the clamping plate 3, the lap plate 4 is inclined to one side of the steel structure, and the upper edge of the lap plate 4 is overlapped on the outer wall of the steel structure; the lap plate 4 and the clamping plate 3 can be hinged by ordinary hinges, latch hinges 8 or spring hinges. When the spring hinge is used, the lap plate 4 and the clamping plate 3 are at an angle of 90 degrees in the absence of external force. As the size of the steel structure increases, the angle between the lap plate 4 and the clamping plate 3 increases. The four lap plates 4 have a clamping force on the steel structure at the same time, which prevents the device from sliding up and down on the steel structure.

[0024] Furthermore, a protective baffle 5 is provided on the side of the collecting trough 1 away from the steel structure. The protective baffle 5 is vertically arranged, and the upper edge of the protective baffle 5 is 8 cm higher than the upper edge of the collecting trough 1 to prevent the falling welding slag from splashing. In this embodiment, the four protective baffles 5 are also connected in the form of a square frame, and the adjacent two protective baffles 5 at the four corners of the square frame are also connected by a latch hinge 8.

Connectors are arranged at both ends of the exhaust pipe 9. One end is connected to the connecting pipe 7 through the connector, and the other end is connected to the air inlet of the air pump 10 through the connector. The air pump 10 is a micro air pump 10. An air pump bracket is arranged on the lower side of the protective baffle 5. The micro air pump 10 is installed on the air pump bracket. A protective cover is arranged at the air outlet of the air pump 10.

[0026] The welding slag collection mechanism can collect the welding slag dropped during high-altitude welding operations, thereby preventing the falling of welding slag during high-altitude welding from causing fires in the materials below or burning the construction workers below; the smoke collection mechanism can discharge the smoke generated by welding from below, preventing the workers from accidentally inhaling toxic gases into their bodies during construction, and providing the workers with a safer working environment.
