A Turnable Portable Folding Pile Windshield

Abstract

The invention discloses a turnable portable folding windshield for pile connection, which comprises: a first baffle; a second baffle, one side of which is rotatably connected to one side of the first baffle; The other side of the second baffle is rotatably connected; one side of the fourth baffle is rotatably connected to the other side of the third baffle; the fixing mechanism is multiple and corresponds to each baffle one by one and is fixedly arranged on each baffle The lower end of the plate; the first baffle plate, the second baffle plate, the third baffle plate and the fourth baffle plate all include a connecting frame of a rectangular frame structure and a connecting plate fixed in the rectangular frame structure of the connecting frame, and the connecting plate The upper end of the second air guide plate and the connecting frame form an air guide window, and an air guide channel is formed between the first air guide plate and the second air guide plate. Guide to dissipate the irritating gas generated during the welding process without interfering with the 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
