Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sewage pipeline construction and relates to a sewage pipeline joint elastic sealing filler coating device. Background Art
[0002] During the construction of sewage pipes, the jacking method is usually used to connect the segmented pipes. During the jacking process, in order to avoid collisions at the joints of the segmented pipes and cause damage to the segmented pipes, a wooden gasket is usually placed after jacking a section of the pipe, and then the next section of the pipe is jacked in. When the next section of the pipe is jacked in, the wooden gasket will have a certain buffering effect on the pipe and separate the pipes at both ends to prevent direct collisions and prevent the pipes from being damaged by collisions. Therefore, the joint between the two sections of the pipe is a wooden gasket, and the wooden gasket is a ring-shaped structure, and its side wall thickness is smaller than that of the pipe side wall thickness. Therefore, a joint will be generated at the internal joint of the two sections of the pipe. In order for the sewage to flow normally in the pipe later, it is necessary to apply elastic sealing fillers (such as Figure 1 As shown), on the one hand, it increases the sealing of the pipeline and prevents water leakage at the pipeline joints. On the other hand, it fills the joints at the two ends of the pipeline joints and plays a bonding role on the two sections of the pipeline, thereby strengthening the connection strength of the two sections of the pipeline.
[0003] At present, the application of elastic sealing fillers at pipe joints is mainly done manually, in a manner similar to cake decorating, using flexible materials, such as plastic cloth, to wrap the elastic sealing fillers, and then squeezing the elastic sealing fillers from the flexible material into the joints for application. However, manual application requires a lot of manpower and construction workers consume a lot of physical energy, resulting in low coating efficiency and high labor costs. In addition, manual application can easily lead to uneven coating of the elastic sealing fillers in the joints. After coating, the surface of the coating cannot remain relatively flush with the inner wall surface of the pipe, resulting in poor coating quality.
[0004] Therefore, it is necessary to provide a device for coating elastic sealing filler at the joints of sewage pipes. During the construction process, construction workers use the device to coat the elastic sealing filler, which reduces manpower consumption, reduces labor costs, improves work efficiency, and improves the relative flatness of the coating surface and the inner wall of the pipe and the coating uniformity, thereby improving the coating quality. Utility Model Content
[0005] In order to overcome the problems in the background technology, the utility model adds elastic sealing filler into the storage box, and the electric push rod drives the push plate to move, and the elastic sealing filler is extruded through the discharge head. During the extrusion process of the elastic sealing filler, the U-shaped guide device is inserted into the joint to play a guiding role, so that the discharge head is aligned with the joint, and the elastic sealing filler directly enters the joint after being extruded. By applying force, the first walking wheel moves on the inner wall of the pipe, and the device can move one circle along the trajectory of the joint. During the movement, the elastic sealing filler is extruded into the joint, saving the physical strength of the construction workers, improving the construction efficiency, and reducing the labor cost and manpower consumption. At the same time, the excess elastic sealing filler is scraped off by the scraper plate, so that after the elastic sealing filler is applied, its surface is kept relatively flush with the surface of the inner wall of the pipe, and at the same time, the elastic sealing filler applied in the joint is more uniform, thereby improving the coating quality of the elastic sealing filler.

DETAILED DESCRIPTION
[0028] The present invention will be further described in detail below in conjunction with specific embodiments.
[0029] like Figure 2-7 As shown, the coating device includes a storage box 1, a discharge head 2, a push plate 3, an electric push rod 4, a hollow connecting rod 5, a handle 6, a U-shaped guide device 7, a first walking wheel 8, and a scraper plate 12. The discharge head 2 is detachably connected to the bottom of the storage box 1, and the top of the storage box 1 is fixedly connected to the handle 6 through the hollow connecting rod 5. The electric push rod 4 is located in the hollow cavity of the hollow connecting rod 5, and the bottom of the electric push rod 4 is fixedly connected to the top of the hollow connecting rod 5. The telescopic end of the electric push rod 4 passes through the storage box 1 and is fixedly connected to the push plate 3 located in the storage box 1. The first running wheels 8 are fixedly installed on two opposite side walls of the storage box 1, a U-shaped guide device 7 is fixedly arranged on one side wall of the storage box 1 where the first running wheel 8 is not installed, and a scraper plate 12 is fixedly arranged on the bottom of the other side wall of the storage box 1 where the first running wheel 8 is not installed, the lowest point of the first running wheel 8 is not higher than the horizontal plane where the outlet position of the discharge head 2 is located, the vertical section of the U-shaped guide device 7 is a square rod structure, and its lowest point is lower than the lowest point of the first running wheel 8, and the bottom of the scraper plate 12 is located in the same horizontal plane as the lowest point of the first running wheel 8.
[0030] When it is necessary to apply the elastic sealing filler 15, first remove the discharge head 2 installed on the storage box 1, add the elastic sealing filler 15 into the storage box 1 through the connection port between the discharge head 2 and the storage box 1, and then install the discharge port 2 on the storage box 1. At this time, the electric push rod 4 is in a shortened state, and the push plate 3 is located at the top of the storage box 1. After the material addition is completed, the construction personnel insert the vertical section of the U-shaped guide device 7 into the joint so that the vertical sections on both sides of the U-shaped guide device 7 are in contact with the pipe ends on both sides of the joint. , the vertical section is a square rod structure, and one side of the square rod is in contact with the end of the pipe, so that the U-shaped guide device 7 is not easy to rotate when moving in the joint, and the first running wheel 8 is in contact with the inner wall of the pipe 13. At the same time, since the bottom of the scraper plate 12 and the lowest point of the first running wheel 8 are located in the same horizontal plane, the scraper plate 12 is also in contact with the inner wall of the pipe 13. Then the construction worker holds the handle 6 with one hand and the hollow connecting rod 5 with the other hand. Holding the handle 6 mainly applies a force perpendicular to the inner wall of the pipe 13 to the device, so that the U-shaped guide device The device 7 is always in the joint and does not fall out during the movement of the device. At the same time, the first running wheel 8 and the scraper plate 12 are close to the inner wall of the pipe 13. The other hand holds the hollow connecting rod 5 and applies a force to the device to move the device, so that the first running wheel 8 can roll on the inner wall of the pipe, so that the device moves along the joint track. During the movement, the electric push rod 4 is started, the electric push rod 4 extends, and the push plate 3 moves, and the elastic sealing filler 15 in the storage box 1 is squeezed out from the discharge head 2. Due to the U-shaped guide The device 7 is inserted into the joint, which can ensure that the discharge head 2 is always aligned with the joint, so that the extruded elastic sealing filler 15 enters the joint. In order to make the amount of elastic sealing filler 15 in the joint more sufficient, more elastic sealing filler 15 is usually extruded to fill the joint. The scraper plate 12 can scrape away the elastic sealing filler 15 during the movement, so that after the elastic sealing filler 15 is applied, the joint of the pipe 13 and the inner wall of the pipe 13 remain relatively flat, and the amount of elastic sealing filler 15 in the joint is also relatively uniform. During the application of the elastic sealing filler 15, the push plate 3 is driven by the electric push rod 4 to extrude the elastic sealing filler 15, without manual extrusion, which is conducive to reducing the physical exertion of construction personnel and improving work efficiency. If the electro-hydraulic push rod 4 needs to be connected to a wired power supply, a hole is opened on the side wall of the hollow connecting rod 5 and the power supply is connected.During the movement of the device, it is necessary to let the U-shaped guide device 7 pass through the same position of the joint first, and then the discharge head 2 reaches the direction of this position for construction to prevent the elastic sealing filler 15 from blocking the U-shaped guide device 7. After the elastic sealing filler 15 is finally coated, it presents a ring structure, that is to say, when there is a small position left uncoated, if the device moves again, the U-shaped guide device 7 will be blocked by the elastic sealing filler 15 that has been coated at the starting point. Therefore, the last uncoated position needs to be manually supplemented. Compared with manual coating, the use of this device for coating still has a better effect.
[0031] The horizontal section of the U-shaped guide device 7 is a slide rail structure, which is fixedly arranged on the side wall of the storage box 1. The vertical section of the U-shaped guide device 7 is fixedly connected to the sliding part of the slide rail structure, and the sliding part of the slide rail structure is locked by bolts.
[0032] By sliding the sliding part of the slide rail structure, the sliding part of the slide rail structure can be slid according to the width of the joint, thereby adjusting the spacing of the vertical sections of the U-shaped guide device 7, so that the vertical section spacing can be inserted into joints of different widths for guiding. After adjusting to the appropriate width, the sliding part is locked by bolts to prevent the sliding part from sliding randomly during use, causing the U-shaped guide device 7 to lose its guiding function.
[0033] The vertical section of the U-shaped guide device 7 is a telescopic structure, the lowest point of the telescopic structure joint is not lower than the lowest point of the first running wheel 8, and the telescopic structure is locked by bolts.
[0034] The total length of the vertical section of the U-shaped guide device 7 can be adjusted by the telescopic structure, so that the device can be used to apply the elastic sealing filler 15 when encountering different joint depths.
[0035] The bottom of the vertical section of the U-shaped guide device 7 is installed with a second running wheel 9. After the vertical section of the U-shaped guide device 7 is inserted into the joint, the end of the vertical section may contact the wooden gasket, and during the movement of the device, friction will be generated to hinder the movement, resulting in inconvenience in moving the device. After the second running wheel 9 is installed, the second running wheel 9 rolls on the wooden gasket to reduce friction and facilitate the movement of the device.
[0036] A threaded hole is provided at the bottom of the material storage box 1, and the discharge head 2 is connected to the bottom of the material storage box 1 via threads.
[0037] When the elastic sealing filler 15 is added into the material storage box 1 , it can be added through the threaded hole at the bottom of the material storage box 1 .
[0038] A slide groove 10 is provided on the side wall of the material storage box 1 , and the push plate 3 is slidably connected to the material storage box 1 via a slider 11 in the slide groove.
[0039] The push plate 3 is slidably connected to the material storage box 1, which can improve the stability of the push plate 3 during the process of squeezing the elastic sealing filler 15 and minimize the possibility of the push plate 3 shaking left and right.
[0040] The area of the push plate 3 matches the horizontal cross-sectional area of the cavity of the material storage box 1 .
[0041] Working process of the utility model: when it is necessary to carry out the coating work of elastic sealing filler, the construction personnel first add the elastic sealing filler into the storage box, then install the discharge head, and then insert the U-shaped guide device into the joint, turn on the electric push rod, squeeze the elastic sealing filler into the joint, and hold the device to move it along the joint track to complete the coating. When a circle of joints is about to be coated, the construction personnel turn off the electric push rod, pull the U-shaped guide device out of the joint, and manually fill the last uncoated joint.
[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
