Flexible portable type folding and pile-splicing windscreen

Abstract

The invention discloses a flexible portable type folding and pile-splicing windscreen. The flexible portable type folding and pile-splicing windscreen comprises a first baffle plate, a second baffle plate, a third baffle plate, a fourth baffle plate and a plurality of fixed mechanisms, wherein one side of the second baffle plate is rotatably connected to one side of the first baffle plate; one side of the third baffle plate is rotatably connected to the other side of the second baffle plate; one side of the fourth baffle plate is rotatably connected to the other side of the third baffle plate;the fixed mechanisms are in one-to-one correspondence to the baffle plates, and are separately arranged at the lower ends of the baffle plates fixedly; each of the fixed baffle plate, the second baffle plate, the third baffle plate and the fourth baffle plate comprises a connecting framework of a rectangular frame body structure, and a connecting plate fixed in the rectangular frame body structure of the connecting frame, wherein the upper end of a second air guide plate of the connecting plate and the connecting framework define an air guide window, and an air guide channel is formed betweena first air guide plate and the second air guide plate. According to the scheme adopted by the invention, the flexible portable type folding and pile-splicing windscreen is good in windscreen effect,is not liable to laterally move, can guide certain amount of air flow, and disperses irritant gas generated in a welding process without distributing welding operation.

Description

technical field [0001] The invention relates to the field of pile connection auxiliary devices, in particular to a turnable portable foldable pile connection windshield. Background technique [0002] Pile connection means that because the length of a pile does not reach the depth specified in the design, it is necessary to connect the prefabricated piles one by one and continue to drive down until they reach the designed depth. The upper and lower piles need to be welded and fixed to ensure that they can cooperate well. Since the construction site where piles need to be connected is often a relatively wide area, when the operator performs pile welding, it is often necessary to butt the piles. Install a windshield around the welding area to prevent the ambient wind from interfering with the normal welding operation. If the wind at the construction site is too high, it will cause slag inclusions, welding bumps and air holes during the welding operation, which directly affects ...

Problems solved by technology

The upper and lower piles need to be welded and fixed to ensure that they can cooperate well. Since the construction site where piles need to be connected is often a relatively wide area, when the operator performs pile welding, it is often necessary to butt the piles. Install a windshield around the welding area to prevent the ambient wind from interfering with the normal welding operation. If the wind at the construction site is too high, it will cause slag inclusions, welding bumps and air holes during the welding operation, which directly affects the welding between the piles. Quality, serious will lead to construction safety accidents

[0003] In the prior art, during pile welding, a windshield device is usually installed to shield the surroundings of the welder from the wind. However, since the construction site is mostly uncemented muddy land, the ground flatness is not good. Therefore, When most of the windshields are used to block the wind, they will continue to shake due to the interference of the wind and generate a lot of low-frequency noise, and they are also prone to sideways movement, making the windshield effect poor or tipping over. Although some heavy windshields The device, such as the patent of Chinese application No. 201821354216.8, can play a certain wind-shielding effect, but it also seriously affects the air flow in the welding environment while shielding the wind. It should be understood that during the welding process, a On the one hand, it will produce a large amount of high-energy arc radiation (including a large amount of ultraviolet rays), on the other hand, it will also produce a large amount of irritating gas, and the irritating gas contains a large number of components that can easily cause respiratory diseases for operators. The density is often higher than that of air, so that sedimentation and accumulation will occur. If the airflow suppression effect of the windshield device is too good, it will easily cause the air around the operating position to be covered by the irritating gas generated by welding, making it difficult for operators to work in this harsh atmosphere. Continuous work, or after continuous work, is likely to cause more serious lung and respiratory occupational diseases, seriously affecting the health of operators
