Description

Technical Field

[0001] The utility model belongs to the field of municipal engineering, and particularly relates to an auxiliary installation tool for rubber rings of drainage pipes. Background Technique

[0002] When docking drainage pipes, a rubber ring needs to be installed at the docking place to prevent water leakage at the interface. Since the rubber ring needs to be installed tightly on the drainage pipe, the rubber ring needs to be stretched open and sleeved on the interface of the drainage pipe. When installing, the rubber ring needs to be stretched even more to be sleeved on. Due to the large diameter of the drainage pipe, a great deal of force is required in the process of stretching the rubber ring, and it is very easy to rebound during the stretching process, causing injury to workers. In addition, when the rubber ring is stretched, if the stretching in all directions is uneven and the stretched shape is not circular, it is more laborious to install, resulting in difficult installation of the rubber ring. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the deficiencies of the background technique and provide an auxiliary installation tool for rubber rings of drainage pipes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0016] This embodiment includes a support frame 1. The support frame 1 includes an upper support plate 2 and a lower support plate 3. The upper support plate 2 and the lower support plate 3 are fixedly connected together by support legs. In this embodiment, both the upper support plate 2 and the lower support plate 3 are triangular plates, and in order to be more stable, the size of the lower support plate 3 is larger than that of the upper support plate 2. An insertion hole is provided in the middle of the upper support plate 2, and a telescopic shaft motor 4 is fixed in the middle of the lower support plate 3. The telescopic shaft of the telescopic shaft motor 4 is vertically upward, and a pull ring 5 is provided at the upper end of the telescopic shaft of the telescopic shaft motor 4.

[0017] This embodiment further includes a sliding rod 6. The diameter of the sliding rod 6 is equal to the diameter of the insertion hole. The sliding rod 6 is inserted into the insertion hole and can slide up and down in the insertion hole. A number of adjustment holes 7 are provided on the sliding rod 6. A number of connecting rods 8 are evenly hinged around the top of the sliding rod 6. In this embodiment, four connecting rods 8 are obliquely hinged downward on the sliding rod 6. A flexible chain 9 is fixed downward at the bottom end of the sliding rod 6. The flexible chain 9 can be selected as an iron chain. A hook 10 is fixed at the lower end of the flexible chain 9. The hook 10 can be hung on the pull ring 5. The sliding rod 6 is connected to the telescopic shaft of the telescopic shaft motor 4 through the hook 10 and the pull ring 5, so that the sliding rod 6 can be pulled downward by the telescopic shaft motor 4.

[0018] A short sleeve 11 is sleeved on the sliding rod 6. The inner diameter of the short sleeve 11 is equal to the diameter of the sliding rod 6, and the outer diameter of the short sleeve 11 is greater than the diameter of the insertion hole. The sliding rod 6 can slide up and down in the short sleeve 11. A through hole 12 matching the adjustment hole 7 is provided on the short sleeve 11. A positioning pin 13 can be inserted into the through hole 12 and the adjustment hole 7. The positioning pin 13 is used to fix the position of the sliding rod 6. A number of struts 14 corresponding to the connecting rods 8 are evenly hinged around the short sleeve 11. Similarly, in this embodiment, four struts 14 are provided. The middle part of the strut 14 is hinged to the lower end of the connecting rod 8. In this way, the sliding rod 6, the short sleeve 11, the strut 14, and the connecting rod 8 form an umbrella-like opening structure. By pulling the sliding rod 6 downward, the strut 14 can be opened outward, and the opening angle can be fixed by the positioning pin 13 after opening.

[0019] A short rod 15 inclined inward is integrally connected to the upper end of the strut 14. The short rod 15 is inclined toward the sliding rod 6. The four short rods 15 can enclose a conical installation opening. The rubber ring is sleeved on the four short rods 15. To prevent the rubber ring from slipping off the upper end of the short rod 15 due to the resilience, a threaded hole 16 is provided at the top of the short rod 15, and a bolt 17 is threadedly connected in the threaded hole 16. The bolt 17 is used to block the rubber ring to prevent it from rebounding and slipping off. To facilitate the removal of the rubber ring, lubricating oil can be applied to the outer surface of the short rod 15 to form a lubricating layer.

[0020] In use, place the short sleeve 11 on the insertion hole, then insert the sliding rod 6 into the short sleeve 11 from top to bottom. Connect the hook 10 at the lower end of the sliding rod 6 to the pull ring 5. Then put rubber rings on the four short rods 15. After putting on the rubber rings, screw the bolts 17 onto the four short rods 15. Then start the telescopic shaft motor 4 to make the telescopic shaft of the telescopic shaft motor 4 move downward, pulling the sliding rod 6 to slide downward. Since the sliding rod 6 moves downward, the connecting rod 8 is pushed outwards, so that the support rod 14 rotates outwards. The four support rods 14 open outwards, and the rubber ring is gradually stretched. When the rubber ring is stretched to the appropriate diameter, insert the positioning pin 13 into the through hole 12 and the corresponding adjustment hole 7 to position the sliding rod 6. At this time, the sliding rod 6 can no longer slide up and down, and the telescopic shaft motor 4 stops working. Disconnect the hook 10 from the pull ring 5, and then pull the sliding rod 6 out of the insertion hole upwards. Then the sliding rod 6, the short sleeve 11, etc. are removed upwards from the support frame 1. Then take it to the position of the drainage pipe, place the sliding rod 6 horizontally, align the drainage pipe and let the short rod 15 sleeve on the drainage pipe. After the rubber ring reaches the installation position, unscrew the bolt 17 on the short rod 15, then push the rubber ring to make it slide down onto the drainage pipe, and at the same time pull the short rod 15 backward, and slide the tool horizontally out of the drainage pipe. Then the rubber ring is installed.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
