[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0033] Please also refer to Figures 1 to 6 Now, a water supply and drainage pipe installation and docking device provided by the utility model is described. In the water supply and drainage pipe installation and docking device, a pre-buried pit 1 is provided with an avoidance pit 11 at the connection position of the two sections of pipes 2, and the installation and docking device is arranged in the avoidance pit 11; the installation and docking device includes a first support frame 3, a second support frame 4 and a driving mechanism 5; the first support frame 3 is arranged below one section of the pipe 2; the second support frame 4 is arranged below the other section of the pipe 2; the driving mechanism 5 is arranged on the first support frame 3; the driving end of the driving mechanism 5 is detachably connected to the second support frame 4; wherein, the top of the first support frame 3 and the top of the second support frame 4 are both provided with a clamping mechanism 6, and the clamping mechanism 6 is used to clamp the pipe 2; when the ends of the two sections of pipe 2 contact each other, a welding space 31 is formed between the first support frame 3 and the second support frame 4, and the welding space 31 is located directly below the connection position of the two sections of pipe 2.
[0034] The utility model provides a water supply and drainage pipe 2 installation and docking device. Compared with the prior art, when two sections of pipe 2 need to be welded, an avoidance pit 11 is set in the pre-buried pit 1, and the first support frame 3 and the second support frame 4 are placed in the avoidance pit 11; the clamping mechanism 6 on the first support frame 3 clamps one section of the pipe 2, and the clamping mechanism 6 on the second support frame 4 clamps the other section of the pipe 2; the first support frame 3 and the second support frame 4 are driven to approach each other by the driving mechanism 5, so that the ends of the two sections of pipe 2 can be brought into contact with each other; after the two sections of pipe 2 are docked, the welding space 31 formed between the first support frame 3 and the second support frame 4 is located directly below the connection position of the two sections of pipe 2; therefore, by setting the welding space 31, it is convenient for the operator to weld the connection position of the two sections of pipe 2.
[0035] In some embodiments, as Figures 1 to 6 As shown, the first support frame 3 and the second support frame 4 both include a left splicing frame 32 and a right splicing frame 33, and the left splicing frame 32 and the right splicing frame 33 are detachably connected; the top and side of the left splicing frame 32 and the right splicing frame 33 both have connecting plates 34, and the connecting plates 34 are connected to the left splicing frame 32 and the right splicing frame 33 by bolts.
[0036] It should be noted that during installation, the left splicing frame 32 and the right splicing frame 33 are respectively slid from the two sides of the pipe 2 toward the middle. After the left splicing frame 32 and the right splicing frame 33 are slid into place, the connecting plate 34 is placed at the connection position of the left splicing frame 32 and the right splicing frame 33, and the connecting plate 34 is fixed to the left splicing frame 32 and the right splicing frame 33 by bolts, so that the left splicing frame 32 and the right splicing frame 33 can form a whole. After the two sections of pipe 2 are welded, the connecting plate 34 is removed from the left splicing frame 32 and the right splicing frame 33, so that the left splicing frame 32 and the right splicing frame 33 can be slid out from the two sides of the pipe 2 respectively, thereby separating the device from the pipe 2.
[0037] In some embodiments, as Figures 1 to 6 As shown, the clamping mechanism 6 includes a base 61, the top of the base 61 has an arc surface for contacting the outer wall of the pipe 2; the base 61 includes a left support 611 connected to the left splicing frame 32 and a right support 612 connected to the right splicing frame 33; wherein, the left support 611 and the right support 612 are both hinged with an arc plate 62, and the two arc plates 62 are used to clamp the pipe 2; a groove 621 is provided on the outer wall of the arc plate 62 near the top, and the two arc plates 62 have through holes aligned with each other at the position of the groove 621; the groove 621 positions of the two arc plates 62 are fixed by bolts and nuts.
[0038] It should be noted that after the left support 611 and the right support 612 are fixed together by the connecting plate 34, by rotating the arc plate 62, the arc surface on the arc plate 62 can be brought into contact with the outer peripheral wall of the pipe 2, and the through holes on the two arc plates 62 are aligned with each other. At this time, the threaded end of the bolt passes through the through holes on the two arc plates 62, and through the cooperation of the nut and the bolt, the two arc plates 62 can be fixed together, so that the two arc plates 62 clamp the pipe 2.
[0039] Specifically, the bottom end of the arc plate 62 has a rotating shaft 64, and the left support 611 and the right support 612 both have a sleeve 63, and the rotating shaft 64 rotates with the sleeve 63; wherein, the bottom end of the arc plate 62 has a rounded corner 622 on the side close to the pipe 2; taking the left support 611 as an example, through the above setting, the arc plate 62 is rotatably set around the rotating shaft 64 on the left support 611; by rotating the arc plate 62 upward, the arc plate 62 can be buckled on the pipe 2; after welding is completed, by rotating the arc plate 62 downward, the arc plate 62 can be separated from the pipe 2.
[0040] In some embodiments, as Figures 1 to 6As shown, the drive mechanism 5 includes a mounting frame 51, a drive plate 52, and a hydraulic cylinder 54. The mounting frame 51 is connected to one side of the first support frame 3; the drive plate 52 is connected to the other side of the second support frame 4. The drive plate 52 is arranged corresponding to the mounting frame 51 and has a through hole. The hydraulic cylinder 54 is fixed to the mounting frame 51. The piston rod of the hydraulic cylinder 54 can pass through the through hole of the drive plate 52. The protruding end of the piston rod of the hydraulic cylinder 54 has an external thread and a nut. The first support frame 3 is provided with a guide hole 35, and the second support frame 4 is fixed with a guide post 36. The guide post 36 slides with the guide hole 35. The guide hole 35 is a polygonal hole, and the guide post 36 has a polygonal structure.
[0041] It should be noted that the first support frame 3 and the second support frame 4 are respectively installed on the two sections of the pipeline 2. After the first support frame 3 and the second support frame 4 are respectively fixed on the pipeline 2, the guide column 36 on the second support frame 4 is inserted into the guide hole 35 on the first support frame 3; at this time, the piston rod of the hydraulic cylinder 54 passes through the drive plate 52, and the protruding end of the piston rod is connected by a nut, and then the piston rod is retracted, which can enable the first support frame 3 and the second support frame 4 to slide relative to each other, thereby facilitating the end portions of the two sections of the pipeline 2 to contact each other, thereby facilitating the operator to weld the connection position of the two sections of the pipeline 2.
[0042] In some embodiments, as Figures 1 to 6 As shown, the mounting frame 51 is a U-shaped structure, and the hydraulic cylinder 54 is located on the mounting frame 51; one end of the hydraulic cylinder 54 contacts one end of the mounting frame 51, and the other end of the hydraulic cylinder 54 contacts the other end of the mounting frame 51; one end of the mounting frame 51 has a socket 53 for inserting a piston rod, and the socket 53 is connected to the top of the mounting frame 51.
[0043] It should be noted that when the hydraulic cylinder 54 is placed on the mounting frame 51, the ends of the mounting frame 51 can axially limit the ends of the hydraulic cylinder 54. During the retraction of the piston rod, the position of the hydraulic cylinder 54 and the first support frame 3 does not change, and the first support frame 3 and the second support frame 4 can slide relative to each other. In addition, the provision of the socket 53 on the mounting frame 51 facilitates the placement of the hydraulic cylinder 54 on the mounting frame 51.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
