Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically to a welding device for inspection wells. Background Technology

[0002] The manhole base of plastic inspection wells is mostly made through one-time injection molding, using accessories such as reducers, angle reducers, and rubber sealing rings to achieve connections that change pipe diameter and angle. Plastic inspection wells are equipped with manhole covers, manhole casings, and related accessories. Road loads are transferred to the area around the inspection well through the manhole cover and base, preventing damage from road loads. The manhole base has a floating function, actively adapting to changes in road surface elevation. The manhole casing uses a specialized design, which can be cut to the appropriate length according to the burial depth, offering flexibility and convenience. The connection between the manhole casing, inlet / outlet pipes, and manhole base uses a flexible socket connection with rubber sealing rings or a heat-shrink sleeve connection, which can adapt to small-range angle changes. Construction is convenient and quick, with good sealing performance and leak-proof properties, effectively preventing secondary pollution of groundwater. It is an environmentally friendly and energy-saving building material.

[0003] Currently, with the development of manholes, in order to improve the utilization rate of molds, when existing manhole products undergo diameter changes, such as converting OD700 to OD630, an OD700×OD630 conversion joint is required. The conversion joint needs to be welded during the diameter change process, and manual welding is performed by injection molding of raw materials using a heating gun.

[0004] Among the challenges are low welding efficiency, large-diameter inspection well support openings, and large rotation during manual welding, which makes welding difficult and affects welding quality. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to disclose a welding device for inspection wells, so as to improve the problems of low welding efficiency of existing inspection wells, large-diameter inspection well support opening size, large rotation range during manual welding, which causes welding difficulties and thus affects the welding quality.

[0006] To achieve the above and other related objectives, the present invention discloses a welding apparatus for inspection wells, comprising:

[0007] Supporting framework;

[0008] A limiting component is located on the support frame, and a welding inspection well is connected to the limiting component, wherein the limiting component includes:

[0009] A limiting block is slidably disposed on the support frame, and an opening is provided on the limiting block;

[0010] Multiple rollers are rotatably connected to the limiting block, and the rollers are disposed at the opening, wherein the axis of the rollers is parallel to the axis of the inspection well; and

[0011] A drive mechanism, connected to the support frame, is used to drive the inspection well to rotate along its axis;

[0015] The limiting block is connected to the top plate, and the driving mechanism is located on the bottom plate.

[0016] In one embodiment of the present invention, the driving mechanism includes:

[0017] The motor is fixedly connected to the base plate; and two sets of drive rollers are rotatably connected to the support frame, and the inspection well is disposed on the two sets of drive rollers; wherein, the motor and the drive rollers are connected by belt drive.

[0018] In one embodiment of the present invention, a limiting wheel is further included, which is located on the support frame; wherein the belt is connected to the limiting wheel via a transmission.

[0019] In one embodiment of the present invention, an adjustment mechanism is further included, located between the limiting block and the top plate, the adjustment mechanism comprising:

[0020] The screw is helically connected to the top plate;

[0021] At least one set of guide rods is arranged parallel to the screw, and the guide rods are slidably connected to the top plate, with one end of each guide rod fixedly connected to the limiting block; and

[0022] The connecting block is located on the limiting block, and the connecting block and the limiting block are rotatably connected;

[0038] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0039] Please see Figures 1 to 3 It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0040] Please see Figure 1 This invention discloses a welding device for inspection wells 500, which can improve the low welding efficiency of existing inspection wells 500. Furthermore, the large diameter of the inspection well 500's support opening results in a large rotation range during manual welding, causing welding difficulties and affecting welding quality. The welding device for the inspection well 500 may include a support frame 100, a limiting component, and a welding component, with the welding component located on one side of the support frame 100. The limiting component is mounted on the support frame 100, and the inspection well 500 for welding is connected to the limiting component. It should be noted that the limiting component allows the inspection well 500 to rotate along its own axis, facilitating welding of the inspection well 500 by the welding component.

[0041] The welding assembly connects the inspection well 500 to the conversion joint 510, which is coaxially arranged with the inspection well 500. A filler strip may be provided between the conversion joint 510 and the inspection well 500 to ensure their coaxiality and thus a uniform gap. This uniform gap facilitates welding between the conversion joint 510 and the inspection well 500.

[0042] Please see Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the support frame 100 may be a frame structure welded by angle iron, and the support frame 100 is provided with at least a top plate and a bottom plate 110, and the top plate and the bottom plate 110 may be arranged in parallel.

[0043] Specifically, the limiting component is located on the support frame 100, and the limiting component is allowed to be located between the top plate and the bottom plate 110.

[0044] The limiting assembly may include a limiting block 300, multiple rollers 310, and a drive mechanism. The limiting block 300 is connected to the top plate, and the drive mechanism is located on the bottom plate 110. It is understood that the inspection well 500 for welding is positioned between the limiting block 300 and the drive mechanism, so that the limiting well can be rotated by the drive mechanism.

[0045] Please see Figure 1 and Figure 2 As shown, in one embodiment, the limiting block 300 is allowed to slide relative to the support frame 100 to facilitate clamping the inspection well 500 between the limiting block 300 and the drive mechanism. Specifically, an adjustment mechanism is provided on the top plate, and the limiting block 300 is connected to the top plate through the adjustment mechanism.

[0046] The adjusting mechanism may include a screw 320, at least one set of guide rods 330, and a connecting block 340 connected to the screw 320. Specifically, the screw 320 is threaded onto the top plate, and one end of the screw 320 is fixedly connected to the connecting block 340, with the rotation centers of the screw 320 and the connecting block 340 coinciding. Therefore, by driving the connecting block 340 to rotate, the screw 320 can be rotated. One end of the guide rod 330 is fixedly connected to the connecting block 340, and the axis of the guide rod 330 is parallel to the axis of the screw 320. The guide rod 330 is slidably connected to the top plate to prevent the limiting block 300 from swaying. Therefore, by driving the connecting block 340 to rotate, the limiting block 300 can move along the axial direction of the screw 320.

[0047] Specifically, the limiting block 300 has an opening 301, and the opening 301 points towards the manhole 500. It can be understood that the manhole 500 is set inside the opening 301 so that the manhole 500 can be limited through the opening 301.

[0048] Please see Figure 1 and Figure 2As shown, in one embodiment, the opening 301 is provided with a plurality of rollers 310, and the rollers 310 are rotatably connected to the limiting block 300. It should be noted that the axes of the rollers 310 and the axis of the inspection well 500 are parallel, and the outer diameter of the inspection well 500 is connected to the rollers 310. Therefore, when the inspection well 500 rotates, the rollers 310 are allowed to rotate. Furthermore, the limiting block 300 is connected to the inspection well 500 via the rollers 310, ensuring a certain pressure while further ensuring the stable rotation of the inspection well 500.

[0049] Please see Figure 1 and Figure 2 As shown, in one embodiment, the drive mechanism is located on the base plate 110 and is connected to the inspection well 500 in a transmission manner. Therefore, the inspection well 500 can be driven to rotate by the drive mechanism.

[0050] Specifically, the drive mechanism may include a motor 200 and two sets of drive rollers 210, with the motor 200 and drive rollers 210 connected by a belt drive. The motor 200 is fixedly connected to the base plate 110, and the drive rollers 210 are rotatably connected to the support frame 100. The inspection well 500 for welding is mounted on the two sets of drive rollers 210. Furthermore, the axis of the drive rollers 210 is parallel to the axis of the inspection well 500, so that when the drive rollers 210 rotate, they can drive the inspection well 500 to rotate.

[0051] The support frame 100 also includes a rotatable limit wheel 220, which is located between the two sets of drive rollers 210. Therefore, the belt used to drive the drive rollers 210 is tensioned and connected to the limit wheel 220 to adjust the belt tension during rotation by limiting its position.

[0052] Please see Figure 1 and Figure 2 As shown, in one embodiment, the welding assembly is located on one side of the support frame 100, and the welding head of the welding assembly is directed into the gap between the inspection well 500 and the transition joint 510. Therefore, when the inspection well 500 rotates, it is permissible to perform a fixed welding between the inspection well 500 and the transition joint 510 via the welding assembly.

[0053] The welding assembly can be manufactured using an injection molding machine 400, which is equipped with an injection gate. During the rotation of the inspection well 500, the injection molding machine 400 can supply molten adhesive through the injection gate, and the molten adhesive located in the gap between the inspection well 500 and the conversion joint 510 can be flattened at the front position of the injection gate. Therefore, by flattening the molten adhesive, the welding effect of this device in actual use can be effectively improved.

[0054] In summary, this invention discloses a welding device for a manhole 500. By setting the adapter 510 and the manhole 500 coaxially, the gap between the adapter 510 and the manhole 500 can be effectively ensured to be uniform. The limiting block 300 is connected to the manhole 500 via a roller 310, ensuring a certain pressure while further ensuring stable rotation of the manhole 500. Furthermore, during the rotation of the manhole 500, a welding assembly can be used to fix the manhole 500 and the adapter 510, and the molten adhesive within the gap between the manhole 500 and the adapter 510 is flattened by the pre-sleeve position of the injection gate, thereby improving the actual welding effect.

[0055] Therefore, it can effectively improve the problem of low welding efficiency of existing inspection wells 500, and the large diameter of the support opening of the large-diameter inspection well 500, which causes large rotation during manual welding, making welding difficult and affecting the welding quality.

[0056] Therefore, this invention effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
