DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Specific embodiments of the adjustable curved surface fire connection device of the present invention:

[0026] like Figure 1 As shown, the adjustable curved surface fire connection device includes a rectangular fire connection storage bin 1, a hoisting assembly connected to the fire connection storage bin 1, and a fixing assembly connected to the hoisting assembly for fixing the entire fire connection device at a specific position.

[0027] Specifically, the length direction of the fire connection storage bin 1 is defined as the left-right direction, the height direction is the up-down direction, and the width direction is the front-back direction. In this embodiment, the fire connection storage bin 1 includes a bottom wall 2 and a front side wall 5, a rear side wall, a left side wall 3, and a right side wall 4 arranged around the bottom wall 2. Among them, the top of the left side wall 3 is hinged with a left baffle 14 through a rotating shaft, and the left baffle 14 can swing up and down; the top of the right side wall 4 is hinged with a right baffle 15 through a rotating shaft, and the right baffle 15 is arranged opposite to the left baffle 14, and the right baffle 15 can also swing up and down. The lengths of the left baffle 14 and the right baffle 15 are both less than the length of the fire connection storage bin 1, and the sum of the lengths of the left baffle 14 and the right baffle 15 is less than the length of the fire connection storage bin 1, which makes a certain gap between the left baffle 14 and the right baffle 15, and the gap forms a fire connection port 16 for the welding slag to fall into the fire connection storage bin 1. Since the left baffle 14 and the right baffle 15 can be turned up and down, the size of the fire receiving opening 16 can be adjusted in this embodiment.

[0028] The corresponding positions on the front side wall 5 and the rear side wall of the fire storage bin are provided with a slide groove 19 extending in the left and right directions, and the slide grooves 19 on the front side wall 5 and the rear side wall are slidably mounted with a left slider 20 and a right slider 21. Figure 3 As shown, the left slider 20 is connected to the left baffle 14 through the left connecting rod 22, and the right slider 21 is connected to the right baffle 15 through the right connecting rod 23. The left connecting rod 22 and the right connecting rod 23 are both telescopic rods with adjustable lengths. When the left slider 20 is moved to the left, the left connecting rod 22 is extended, and the left slider 20 drives the left baffle 14 to flip downward through the left connecting rod 22; when the left slider 20 is moved to the right, the left connecting rod 22 is shortened, and the left slider 20 drives the left baffle 14 to flip upward through the left connecting rod 22. Similarly, when the right slider 21 is moved to the right, the right connecting rod 23 is extended, and the right slider 21 drives the right baffle 15 to flip downward through the right connecting rod 23; when the right slider 21 is moved to the left, the right connecting rod 23 is shortened, and the right slider 21 drives the right baffle 15 to flip upward through the right connecting rod 23, thereby adjusting the size of the fire receiving port 16.

[0029] There are two fire receiving plates in the fire receiving storage bin 1, namely a left fire receiving plate 12 and a right fire receiving plate 13, and the upper plate surfaces of the left fire receiving plate 12 and the right fire receiving plate 13 are fire receiving surfaces. Figure 1 and Figure 2As shown, the left fire receiving plate 12 and the right fire receiving plate 13 are both bendable curved plates. The corresponding end faces of the left fire receiving plate 12 and the right fire receiving plate 13 are fixedly connected together, the left fire receiving plate 12 is fixedly connected to the bottom of the left slider 20 through the hanging rope 18, and the right fire receiving plate 13 is fixedly connected to the bottom of the right slider 21 through the hanging rope 18. That is, the left slider 20 is connected to the left baffle 14 and the left fire receiving plate 12 at the same time, and the right slider 21 is connected to the right baffle 15 and the right fire receiving plate 13 at the same time. When the left slider 20 is moved to the right, the left slider 20 pulls the hanging rope 18 to bend the left fire receiving plate 12 upward and retract; when the left slider 20 is moved to the left, the left slider 20 puts down the hanging rope 18 to unfold the left fire receiving plate 12. The bending and unfolding principle of the right fire receiving plate 13 is the same as that of the left fire receiving plate 12, which will not be repeated. When the left slider 20 and the right slider 21 are moved left and right, the left fire receiving plate 12 and the right fire receiving plate 13 are bent or expanded, thereby adjusting the fire receiving areas on the two fire receiving plates.

[0030] In order to prevent welding slag from splashing around when it falls on the fire receiving plate, in this embodiment, both the left fire receiving plate 12 and the right fire receiving plate 13 are made of fireproof silica gel plates. The left fire receiving plate 12 and the right fire receiving plate 13 are provided with slag outlets 17 at positions corresponding to the bottom wall. After welding slag or sparks generated by construction welding are collected in the fire receiving storage bin 1 and stored to a certain volume, the high-temperature welding slag or sparks can flow out from the slag outlets after cooling, thereby realizing the cleaning of welding slag.

[0031] The hoisting assembly includes lifting ears 24 arranged at the four corners of the fire storage bin 1, four lifting rods 8 connected to the lifting ears 24 one by one, and a fixing block 11 connected to the end of each lifting rod 8. Figure 1 As shown, each suspension rod 8 is a telescopic rod with adjustable length, including multiple telescopic rod sections 9 of equal length, each telescopic rod section 9 is provided with a positioning hole 10 for fixing and connecting adjacent telescopic rod sections. The upper end of each suspension rod 8 is hingedly connected to a fixing block 11, and the height of the fire storage bin 1 in the vertical direction can be adjusted by adjusting the length of the suspension rod 8.

[0032] The fixing assembly includes a hook 6 installed on the upper part of the fixing block 11, and the hook 6 is used to hook the entire fire connection device at the welding operation position. The hook 6 is provided with a rotating rivet buckle 7, and a magnet 25 is provided at the hooking part of the hook 6. The rotating rivet buckle 7 can be used to adjust the installation angle of the hook; the magnet 25 has an adsorption function, and when the hook cannot be used for fixing at the construction site, it can be placed through the magnet 25 at the end, providing an additional hook fixing method to meet the welding operation requirements at the construction site.

[0033] The adjustable curved surface fire connection device of the present invention is an innovation for collecting and protecting welding slag or sparks in the field of welding fire in construction. It realizes the controllability and operability of the amplitude and range of the fire connection in the horizontal and vertical directions. It is easy to operate, simple to make, and has strong feasibility. It has important practical significance for preventing and eliminating fire safety hazards, and can effectively solve the technical problem that the traditional fire connection device has unsatisfactory fire connection effect. When in use, the hook is fixed at a suitable angle by the rotating rivet buckle on the hook, so that all-round and multi-angle rotation adjustment can be achieved without being restricted by spatial position; the vertical ignition height of the fire storage bin is adjusted by adjusting the length of each hanger rod, and the left slider and / or the right slider in the slide groove are moved to adjust the area of ​​the fire port on the one hand, and on the other hand, the left fire plate and / or the right fire plate are driven to bend or stretch to increase or reduce the size of the fire surface in the horizontal direction, which not only meets the adjustment of the fire range in the horizontal direction, but also meets the adjustment of the fire height and the fire space in the vertical direction, so as to achieve the purpose of efficiently and safely collecting welding slag or fire at the construction site, and minimize or reduce the fire safety hazards in the construction county.

[0034] In other embodiments, the slag outlet may not be provided. In this case, when the welding slag collected in the welding storage bin reaches a certain amount, the welding slag can be directly poured out from the welding storage bin.

[0035] In other embodiments, the left fire receiving plate and the right fire receiving plate can also be made of steel plates. In this case, a protective cover can be provided on the inner wall of the fire receiving storage bin. When welding slag falls on the fire receiving plate and splashes everywhere, it will splash to the position of the protective cover.

[0036] In other embodiments, only three suspension rods may be provided, and the three suspension rods are distributed in a triangle shape.

[0037] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention.
