Description

Technical Field

[0001] This utility model relates to the field of pipeline engineering technology, and in particular to a device for applying adhesive to pipelines. Background Technology

[0002] In the field of basement water supply pipeline engineering, after the water supply pipeline is installed, it is usually necessary to wrap the installed pipeline with rubber and plastic insulation cotton. Under the current technical conditions, the specific operation procedure is as follows: the operator first uses a brush to apply glue, then evenly applies the glue to the outer wall of the pipeline, and then uses the applied glue to adhere the rubber and plastic insulation cotton to the outer wall of the pipeline. This achieves the purpose of protection and heat insulation, reduces the probability of condensation on the outer wall of the pipeline, and ensures the normal operation of the basement water supply pipeline system.

[0003] However, the current method of manually applying adhesive to the outer wall of pipes with a brush has obvious drawbacks, mainly in two aspects: First, the construction efficiency is low, and the speed of manual operation is limited, making it difficult to meet the needs of rapid construction of large-scale pipeline projects; second, the operation is extremely inconvenient, as operators need to frequently adjust their posture and position to apply adhesive, which is not only labor-intensive but also prone to uneven application, affecting the bonding effect of the insulation cotton and the thermal insulation performance of the pipe. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of low construction efficiency and inconvenience in applying adhesive to the outer wall of pipes in the prior art. Therefore, this invention provides a device for applying adhesive to pipes.

[0005] This utility model provides a device for applying adhesive to pipes, comprising: Wheel frame, wherein the wheel frame has a ring structure; A plurality of wheel sets are evenly arranged circumferentially along the inner wall of the wheel frame, and the plurality of wheel sets are used to contact the outer wall of the pipe and roll along the axial direction of the pipe. Several nozzles are evenly arranged circumferentially along the inner wall of the wheel frame; The base is a ring-shaped structure and is coaxially arranged with the wheel frame. The base is connected to the wheel frame through a connecting arm. A brush is provided on the inner side of the base.

[0006] This invention provides a device for applying adhesive to pipes, wherein the wheel frame serves as the skeleton of the entire device. The wheel frame has a ring-shaped structure, which can better conform to the outer contour of the pipe. Several wheel sets are used to contact the outer wall of the pipe, and these wheel sets can drive the entire device to move along the axial direction of the pipe. Several spray nozzles are used to spray adhesive onto the outer wall of the pipe. A base is used to fix the brush, and the base also has a ring-shaped structure, adapted to the shape of the pipe, so that the brush can act evenly on the outer wall of the pipe. The brush is used to evenly spread the adhesive sprayed onto the outer wall of the pipe. The connecting arm connects the base and the wheel frame.

[0007] This invention uses the wheel assembly to move the entire device along the axial direction of the pipe. During this movement, the spray nozzle sprays adhesive onto the outer wall of the pipe, and the brush evenly spreads the adhesive onto the outer wall. Through the coordinated action of these components, the adhesive application to the pipe's outer wall is achieved. Compared to manual adhesive application, this device enables more efficient and convenient application of adhesive to the pipe's outer wall.

[0008] Each wheel set may contain multiple rollers, and the multiple rollers in each wheel set may be arranged along the axial direction of the wheel frame or in a rectangular array.

[0009] Preferably, the wheel assembly includes two rollers arranged axially along the wheel frame. The wheel frame is a ring-shaped structure, and the axial direction of the wheel frame is defined as a straight line passing through the center of the ring-shaped structure and perpendicular to the plane of the ring-shaped structure. With this design, the wheel assembly can form two sets of rollers arranged circumferentially at different positions. These two sets of circumferentially arranged rollers can respectively cover two different cross-sectional positions on the pipe. In this way, the wheel assembly can stably attach to the outer wall of the pipe and can move smoothly and easily along the pipe.

[0010] Preferably, the roller can move closer to or further away from the inner wall of the wheel frame along the radial direction of the wheel frame. In this design, because the roller can move closer to or further away from the inner wall of the wheel frame, the entire device can be adapted to and applied to pipes of more different diameters, improving the flexibility and applicability of the entire device. This design achieves the adjustment of the distance between the roller and the inner wall of the wheel frame in one way: the roller is connected to the inner wall of the wheel frame via a telescopic rod. By controlling the extension or retraction of the telescopic rod, the roller can move closer to or further away from the inner wall of the wheel frame; alternatively, the roller can be equipped with a sliding rod, and a through hole is opened in the wheel frame along the wall thickness direction, allowing the sliding rod to be inserted into the through hole. When the sliding rod slides along the through hole, it can drive the roller closer to or further away from the inner wall of the wheel frame.

[0011] Preferably, the wheel frame has a through hole, and the roller is connected to a sliding rod. The cross-sectional shape of the sliding rod matches the cross-sectional shape of the through hole. The sliding rod is inserted into the through hole and can move radially along the wheel frame, thereby driving the roller closer to or away from the inner wall of the wheel frame. In this design, the sliding rod can be securely and precisely locked within the through hole, ensuring that the through hole can more accurately and effectively guide the movement direction of the sliding rod, preventing the sliding rod from deviating or wobbling during movement. Since the sliding rod extends to the outside of the wheel frame through the through hole, it can be operated directly from outside the wheel frame, facilitating its sliding along the through hole to a predetermined position, improving the convenience and accuracy of operation. The number and position of the through holes are adapted to the number and position of the rollers.

[0012] After the slide bar is moved to the predetermined position, it can be fixed to the wheel frame by a buckle or bolt.

[0013] Preferably, a protruding plate is provided on the outer wall of the wheel frame at the position of the through hole, and a bolt is provided on the protruding plate. By rotating the bolt, the bolt can move closer to or away from the sliding rod. In this design, the protruding plate is fixedly connected to the wheel frame, and its main function is to provide a stable and reliable support structure for the bolt. By rotating the bolt, it is gradually moved closer to the sliding rod until the end of the bolt presses the sliding rod tightly against the inner wall of the through hole. The clamping force generated by the bolt end and the inner wall of the through hole on the sliding rod effectively restricts the sliding rod from sliding relative to the through hole, ensuring the stability of the sliding rod's position within the through hole.

[0014] The cross-sectional shape of the through hole can be circular or rectangular.

[0015] Preferably, the cross-sectional shape of the through hole is rectangular. When the sliding rod slides within the through hole, if the cross-section of the through hole is circular, the cross-section of the sliding rod is also correspondingly circular, and the sliding rod may rotate around its own axis. Once the sliding rod rotates around its axis, the direction of the roller connected to it will change accordingly. Due to the change in the direction of the roller, the contact and force conditions between the entire device and the outer wall of the pipe will change when the device moves along the pipe, thus preventing the device from moving smoothly along the pipe. In this solution, a rectangular cross-section through hole is used, and the cross-section of the sliding rod is correspondingly set to rectangular, which can effectively limit the rotation of the sliding rod around its own axis, thereby avoiding the above-mentioned adverse situation and ensuring that the device moves stably and smoothly on the pipe.

[0016] Preferably, the wheel frame comprises two semi-circular ring-shaped frames, which are detachably connected to form a ring structure. In this design, since the two semi-circular ring-shaped frames are in a separate state, they can be directly enclosed at the middle of the pipe before connection. This allows for easy and convenient installation of the entire device onto the pipe, eliminating the need for the traditional method of slipping the entire device onto the pipe from one end. This design significantly improves the installation flexibility of the device and effectively solves the problem of installation failure when the pipe lacks a free end or is obstructed by a support bracket.

[0017] The connection between the two frames can be a snap-fit ​​connection, a bolt connection, or a pin connection.

[0018] Preferably, the two frames are connected by pins. The pin connection has higher stability and is less prone to loosening or component detachment under normal use and under certain external forces. Compared with bolt connections, the pin connection is simpler and faster to operate, eliminating the need for complex tightening and loosening operations, thus significantly improving connection efficiency and saving time and costs for installation and disassembly.

[0019] Preferably, the spray nozzle includes a nozzle disposed between the base and the wheel frame. In this design, the nozzle is used to spray adhesive onto the outer wall of the pipe. This design allows the nozzle to be positioned closer to the base, which is used to fix the brush, thereby enabling the adhesive sprayed onto the outer wall of the pipe by the nozzle to be applied more quickly by the brush, improving the uniformity of adhesive application.

[0020] Preferably, the nozzle further includes a fixed section and a free section, with the nozzle connected to the free section, which can be bent and shaped. In this design, the fixed section is used to connect to the inner wall of the frame. The free section of the nozzle can be made of stainless steel corrugated pipe or flexible copper pipe. The purpose of using these two pipe materials is to enable the free section to be bent and shaped, that is, the free section can be easily bent and can stably maintain the formed bending shape after bending. This design allows for flexible adjustment of the nozzle position within a certain range. This design has strong adaptability when dealing with pipes of different diameters. Specifically, when the distance between the nozzle and the outer wall of the pipe does not meet the working requirements, that is, the distance is too close or too far, the free section can be easily bent to precisely adjust the position of the nozzle, ensuring that the nozzle maintains a suitable distance from the outer wall of the pipe to meet the needs of the actual working scenario.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a device for applying adhesive to pipes. The wheel assembly drives the entire device to move along the axial direction of the pipe. During movement, the spray nozzle sprays adhesive onto the outer wall of the pipe, and the brush evenly spreads the adhesive onto the pipe's outer wall. Through the coordinated action of the components, the adhesive application to the pipe's outer wall is achieved. Compared to manual adhesive application, this device enables more efficient and convenient application of adhesive to the pipe's outer wall. Attached Figure Description

[0038] Several sets of wheels are evenly arranged circumferentially along the inner wall of the wheel frame 1, and these sets of wheels are used to contact the outer wall of the pipe 7 and roll along the axial direction of the pipe 7. Specifically, the inner diameter of the wheel frame 1 is larger than the outer diameter of the pipe 7, and the sets of wheels are located between the outer wall of the pipe 7 and the inner wall of the wheel frame 1. There are four sets of wheels, arranged circumferentially along the inner wall of the wheel frame 1 at 90° intervals.
