Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a bottom film lubricating device for pipeline repair. Background Art

[0002] UV curing lining repair technology is one of the trenchless on-site curing lining repair methods for drainage pipes. The fiberglass hose soaked with light-curing resin is dragged into the cleaned pipe to be repaired by a winch, connected to the air duct to blow air inward and inflate it to make it close to the inner wall of the pipe. The inner wall of the pipe is irradiated with professional UV light emission and control equipment to cure the resin inside the pipe, forming a new high-strength lining pipe.

[0003] The entry of the liner hose is one of the key procedures of this process. When dragging it in, a bottom film needs to be pre-set inside the pipe to be repaired. The function of the bottom film is to protect the outer wall of the liner. After the bottom film is fixed, the liner should be inserted into the pipe to be repaired along the descending direction using a cable winch and a guide pulley set. In order to reduce the friction generated by dragging and reduce possible damage to the liner during the dragging process, a biodegradable lubricant (generally vegetable oil) is applied to the bottom film before starting the dragging operation. The traditional application method is to use a manual application method. On the one hand, this application method easily makes the lubricant unevenly applied. On the other hand, many repaired pipelines have long paths and long liner hoses, and manual operation is time-consuming and labor-intensive. In view of the shortcomings of the prior art, the utility model provides a bottom film lubrication device for pipeline repair to solve the above problems. Utility Model Content

During the transmission process, the base film drives the lubrication roller to rotate, and the lubrication oil cylinder and the connecting pipe are used to supply oil to achieve rapid lubrication of the base film. The rotating lubrication design of the lubrication roller can, on the one hand, make the base film lubricating oil evenly applied and have a good lubrication effect. On the other hand, it saves manpower and meets usage requirements.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a bottom film lubrication device for pipeline repair, comprising a support base, a bottom film support roller is rotatably connected to the support base, and a lubrication mechanism is provided on the support base, and the lubrication mechanism includes:

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The embodiment of the present application provides a base film lubrication device for pipeline repair, which solves the problem that the traditional application method is a manual application method. On the one hand, this application method easily causes uneven application of the lubricant. On the other hand, many repaired pipelines have long paths and long lining hoses, and manual operation is time-consuming and labor-intensive.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model embodiment discloses a bottom film lubrication device for pipeline repair. Figure 1-5 As shown, it includes a support base 1, a bottom film support roller 2 is rotatably connected to the support base 1, and a lubrication mechanism is provided on the support base 1, and the lubrication mechanism includes:

[0031] A supporting and fixing frame 3 is arranged on the supporting base 1;

[0032] The lubricating oil cylinder 4 is arranged on the supporting frame 3, and a connecting pipe 401 is arranged on the lubricating oil cylinder 4;

[0033] The load-bearing plate 5 is arranged on the supporting and fixing frame 3;

[0034] A slide bar 6 is slidably connected to the bearing plate 5;

[0035] Axle seat 7, arranged at the bottom of the slide bar 6;

[0036] A spring 8 is arranged between the shaft seat 7 and the bearing plate 5;

[0037] The lubricating roller 9 is disposed on the shaft seat 7 . The lubricating roller 9 is connected to the connecting pipe 401 . The lubricating roller 9 is provided with a central groove 901 and a connecting groove 902 for lubricating the base film.

[0038] Furthermore, a guide groove 903 is opened inside the connecting groove 902. Through the design of the guide groove 903 in the device, the lubricating oil will diffuse to various positions of the connecting groove 902 when passing through the connecting groove 902, so that the lubricating oil is evenly distributed inside the connecting groove 902, thereby achieving a good lubrication effect on the base film.

[0039] Specifically, a switch valve 402 is provided on the connecting pipe 401. The switch valve 402 is convenient for controlling the discharge of the lubricating oil in the lubricating oil cylinder 4. When the bottom film is not dragged in, the switch valve 402 is closed to avoid oil leakage.

[0040] The top of the lubricating oil cylinder 4 is threadedly connected with an upper cover 403 , and the upper cover 403 is provided to facilitate the inspection and addition of lubricating oil to the interior of the lubricating oil cylinder 4 .

[0041] Furthermore, a support tube 501 for supporting and limiting the slide bar 6 is fixedly connected to the bearing plate 5 . The support tube 501 is provided to provide lateral support to the slide bar 6 , thereby ensuring that the slide bar 6 is subjected to stable force.

[0042] The slide bar 6 is fixedly connected to a limiting block 601 , and the setting of the limiting block 601 limits the slide bar 6 and prevents it from slipping off.

[0043] The bottom film lubrication device for pipeline repair, when the bottom film needs to be laid and lubricated, firstly, the bottom film is placed between the bottom film support roller 2 and the lubrication roller 9 for transmission. During the transmission process, the bottom film drives the lubrication roller 9 to rotate. When the switch valve 402 is opened, the lubricating oil stored in the lubricating oil cylinder 4 is transmitted to the inside of the lubricating roller 9 through the connecting pipe 401, and then enters the inside of the connecting groove 902 through the central groove 901, so as to adhere to the surface of the bottom film through the connecting groove 902, and the bottom film is quickly lubricated by the lubricating oil.

[0044] In the device, the guide groove 903 is designed so that the lubricating oil spreads to various positions of the connecting groove 902 when passing through the connecting groove 902, so that the lubricating oil is evenly distributed inside the connecting groove 902, thereby achieving a good lubricating effect on the bottom film;

[0045] The spring 8 design in the device can make the shaft seat 7 and the lubricating roller 9 act on the spring elastic force, ensuring that there is pressure between the lubricating roller 9 and the base film and the base film supporting roller 2, so the lubricating roller 9 has good adhesion to the base film surface and good lubrication effect.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
