[0023] See also Figure 1 to Figure 2The present application provides a roof horizontal pipe welding auxiliary device, which is detachably arranged on the top of the bracket corresponding to the two ends of the pipe, including: a fixing component 100 and an auxiliary component 200, the fixing component 100 is detachably connected to the bracket; the auxiliary component 200 includes at least two support plates 210 and a rotating shaft 220, the two support plates 210 are symmetrically arranged at one end of the fixing component 100 away from the bracket, two rotating shafts 220 are arranged between the two support plates 210, both ends of the rotating shaft 220 are vertical and rotationally connected to the two opposite support plates 210, and one side of the rotating shaft 220 is higher than the end of the support plate 210 away from the fixing component 100 and is drivingly connected to the pipe.

[0024] Specifically, both pipes are supported by brackets, and roof horizontal pipe welding auxiliary devices are arranged between the two ends of the two pipes and the brackets. The fixing component 100 adopts but is not limited to a fixing device that can be detachably connected with a wire tie and a steel plate, a rolled strip and a steel plate. Two support plates 210 are arranged, which are symmetrically arranged on the fixing component 100 by welding. The rotating shaft 220 passes through the two oppositely arranged support plates 210 and is perpendicular to the support plates 210. A bearing 221 or other rotatable device is arranged at the connection between the rotating shaft 220 and the support plate 210 to realize the rotation of the rotating shaft 220. The center of the rotating shaft 220 is close to the edge of the support plate 210 away from the end of the fixing component 100, and the surface of the rotating shaft 220 exceeds the edge of the support plate 210 away from the end of the fixing component 100. The distance between two adjacent rotating shafts 220 is not greater than the radius of the pipe, and the specific spacing is adjusted according to the pipe diameter.

[0025] Brackets are installed under both ends of the pipes to be welded, and the fixing assembly 100 is detachably connected to the brackets. The pipes to be welded are placed on the rotating shaft 220. The height of the brackets is adjusted so that the pipes to be welded are level with the installed pipes. The welder stands on the brackets to weld the pipes and uses a pipe clamp to rotate the pipes while welding so that the unwelded part is rotated to an end that is convenient for the welder to weld, and the welding work is completed.

[0026] The present application adopts a technical solution of a roof horizontal pipe welding auxiliary device to achieve the following beneficial effects: 1. By arranging auxiliary components 200 at both ends of the pipe, the pipe rotation is more convenient and supports the operation, thereby solving the problem that the horizontal pipes on the roof of the house are difficult to install at high altitude after being welded on the ground, and the labor intensity is high.

[0027] 2. The rotating shaft 220 is connected to the pipeline transmission to make the pipeline rotate more smoothly, thereby solving the problems of limited welding space for the pipeline close to the roof side, welding difficulties, and welding quality not meeting the standards.

[0028] Based on the above solution, a circular arc-shaped pit 211 is provided in the middle of one end of the support plate 210 away from the fixing assembly, and the rotating shaft 220 is symmetrically arranged on both sides of the pit 211 .

[0029] Specifically, pits 211 are provided on both support plates 210, and the projections of the two pits 211 vertically coincide with the horizontal plane. The diameter of the pit 211 is selected according to the diameter of the pipeline. For example, the pit 211 is half of the pipeline cross-section and has the same diameter. The axis of the rotating shaft 220 is on both sides of the pit 211, and the surface of the rotating shaft 220 extends into the pipeline channel formed by the two pits 211, and is transmission-connected with the pipeline extending into the pipeline channel, thereby making the pipeline more stable and solving the problem of the pipeline detaching from the two rotating shafts 220 during rotation.

[0030] Furthermore, a rubber sleeve is provided on the rotating shaft 220, the length of the rubber sleeve is not greater than the spacing between the two supporting plates 210, and the rubber sleeve is in driving connection with the side of the pipe away from the roof. For example, a rubber sleeve is wrapped on one side of the rotating shaft 220, a plurality of semicircular protrusions are provided on the surface of the rubber sleeve, and the length of the rubber sleeve is three quarters of the spacing between the two supporting plates 210. By providing the rubber sleeve and the semicircular protrusions on the rubber sleeve, the friction between the rubber sleeve and the pipe is increased, so that when the pipe rotates, the rubber sleeve drives the rotating shaft 220 to rotate at the same time, and at the same time, the damage caused by the rotating shaft 220 rubbing against the pipe is avoided.

[0031] In the optimized solution, at least one bearing 221 is provided on the rotating shaft 220, the inner ring of the bearing 221 is fixedly connected to the rotating shaft 220, and the outer ring of the bearing 221 is drivingly connected to the side of the pipeline away from the roof. For example, the rotating shaft 220 is fixedly connected between the two support plates 210 and is located on both sides of the pit 211, at least one bearing 221 is provided, the inner ring of the bearing 221 is fixedly connected to the rotating shaft 220, and the outer ring of the bearing 221 extends into the pipeline channel formed by the two pits 211 and is drivingly connected to the pipeline. By providing the bearing 221, the friction at the connection between the rotating shaft 220 and the support plate 210 is reduced when the rotating shaft 220 rotates, so that the pipeline rotates more smoothly and the operation is more convenient.

[0032] Furthermore, a friction sleeve 222 is provided on the outer ring of the bearing 221, and the friction sleeve 222 is drivingly connected to the end of the pipe away from the roof. For example, the friction sleeve 222 is wrapped on the outer ring of the bearing 221, so that the friction force between the bearing 221 and the pipe is increased. When the pipe is rotated, the rotating shaft 220, driven by the friction sleeve 222, gives the pipe a rotational force in the reverse direction, thereby making the rotation of the pipe simpler and more convenient.

[0033] Based on the above solution, the fixing component 100 includes a U-shaped clamping plate 110 and a fastener 120. The clamping plate 110 is detachably connected to the top of the bracket, and the fastener 120 is arranged at one end of the clamping plate 110 away from the auxiliary component 200.

[0034] Specifically, the open end of the clamping plate 110 is adjusted according to the installation position of the bracket. If the bracket is made of a square tube, the clamping plate 110 can be directly clamped on the bracket. If the bracket is made of a round tube or a scaffold, an arc-shaped clamping groove can be arranged inside the clamping plate 110 to increase the contact area and make the clamping more stable. The fastener 120 can be, but is not limited to, a spring push rod, a telescopic rod, etc. The clamping plate 110 can be more firmly fixed on the bracket through the fastener 120, solving problems such as dropping caused by insecure fixation during the welding process.

[0035] In an optimized solution, the fastener 120 includes a nut 122 and a bolt 121. The nut 122 is fixedly connected to one end of the clamping plate 110 away from the auxiliary component 200, and a through hole is arranged at one end of the clamping plate 110 corresponding to the nut 122 away from the auxiliary component 200. One end of the bolt 121 penetrates through the through hole and is threadedly connected to the nut 122.

[0036] Specifically, a through hole is opened at one end of the clamping plate 110 away from the auxiliary component 200, and the nut 122 is welded and covers the through hole. The bolt 121 extends into the through hole and moves up and down along the inside of the nut 122 by rotation. When the clamping plate 110 is clamped on the bracket, by rotating the bolt 121, the end of the bolt 121 close to the bracket is tightly attached to the bracket. By setting the nut 122 and the bolt 121, the fixation is made more firm, solving the problem that the fastening by means of a spring push rod is not firm enough.

[0037] Based on the above solution, the fastener 120 includes a push plate 123. One end of the push plate 123 is connected to one end of the bolt 121 close to the auxiliary component 200, and the end of the push plate 123 away from the bolt 121 is cooperatively connected to the bracket. For example, the shape of the push plate 123 is adjusted according to the shape of the bracket. The push plate 123 usually uses an arc-shaped or plate-shaped iron plate, and the connection between the push plate 123 and the bolt 121 is connected by a spherical reset device, thereby increasing the contact area with the bracket, reducing the damage of the bolt 121 to the bracket, and at the same time automatically leveling by using the spherical reset device connection to avoid deformation of the push plate 123 or the bracket caused by uneven stress, thereby increasing its service life.

[0038] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application shall be based on the attached claims.
