Description

Technical Field

[0001] This utility model belongs to the field of geothermal pipe processing equipment, specifically, it relates to a long cylindrical workpiece conveying mechanism. Background Technology

[0002] Geothermal pipes are a type of pipe used as a carrier for the circulation of low-temperature hot water in low-temperature hot water radiant floor heating systems (referred to as floor heating).

[0003] To ensure the geothermal pipe system is in optimal working condition, the geothermal pipes are evacuated to remove air and moisture from inside the system.

[0004] When evacuating the geothermal pipes, the pipes need to be adjusted at specific points so that the visual inspection equipment can detect the interfaces on the adjusted pipes and then evacuate them.

[0005] Chinese Patent CN209758262U discloses a chain-plate sawtooth scraper conveyor, including a conveyor body and a drive device. The conveyor body has a chain with a set of flat scrapers and a set of first sawtooth scrapers spaced apart. A second sawtooth scraper is located at the discharge port of the conveyor body, below the chain. The spaced flat scrapers and first sawtooth scrapers facilitate the movement of clumps or strips of chips up the conveyor and carry them out. To prevent clumps or strips of chips from being rolled back into the conveyor, a second sawtooth scraper is provided at the discharge port to scrape off the chips, clumps, and strips conveyed to the discharge port.

[0006] The above technical solution has the following drawbacks:

[0007] Although its technical solution also uses a sawtooth structure for transportation, it is not designed for transporting cylindrical workpieces (geothermal pipes), and it cannot meet the requirements for fixed-point adjustment of the geothermal pipes, making it inconvenient for subsequent docking and vacuuming work. Utility Model Content

[0008] To address the above deficiencies, this utility model provides a long cylindrical workpiece conveying mechanism, including two sets of transfer mechanisms for conveying cylindrical workpieces. Each transfer mechanism includes a base, and the upper surface of the base is connected to a serrated top plate I by a number of equally spaced fixing frames. The two bases are connected to a serrated top plate II adapted to the serrated top plate I by a number of equally spaced progressive parts on the side that is close to each other.

[0009] Both sides of the transition support are provided with adjustment mechanisms that cooperate with the two sets of transfer mechanisms. The adjustment mechanism includes a drive part and an adjustment part.

[0010] The adjustment unit includes a support seat mounted on the top of the slide plate, and a set of rollers for rotating and adjusting the cylindrical workpiece is mounted on the top of the support seat.

[0011] The position of the support base is adjusted by the drive unit.

[0012] Furthermore, the equidistant progressive section includes several cylinders I located at the top of the base. The right end of each cylinder I is hinged to the base, and the telescopic end on the left side of each cylinder I is connected to a sliding component mounted on the upper surface of the base.

[0013] A mounting plate is fixed to the top of the sliding member, and a hinge block I is fixed to the top of the mounting plate. A cylinder II is hinged to the mounting plate. A hinge rod is hinged to the telescopic end on the right side of the cylinder II. The hinge rod is hinged to the hinge block I. The end of the hinge rod away from the cylinder II is hinged to the hinge block II. The top of the hinge block I is fixed to the bottom of the connecting plate. The connecting plate is fixed to the bottom of the sawtooth top plate II.

[0014] Furthermore, the top of the sawtooth top plate I and sawtooth top plate II are toothed grooves for limiting the cylindrical workpiece.

[0015] Furthermore, the drive unit includes a ground rail and a sliding plate slidably mounted on the ground rail. A rack is fixed to the inner wall of the ground rail, and a servo motor is mounted on the top of the sliding plate. The output end of the servo motor passes through the sliding plate and is fixed with a gear that meshes with the rack.

[0016] Furthermore, the inner wall of the support base is equipped with symmetrically arranged electric cylinders I and II. The output ends of electric cylinders I and II penetrate the upper surface of the support base and are respectively connected to lifting plate I and lifting plate II. The top of lifting plate I is equipped with two cooperating rollers, one of which is driven by an asynchronous motor installed on the side wall of lifting plate I. The top of lifting plate II is equipped with a top-mounted conical roller, which is driven by an asynchronous motor installed on the side wall of lifting plate I.

[0017] Furthermore, guide rods are fixed at the corners of the bottom surfaces of the lifting plate I and the lifting plate tool, and each guide rod passes through the limiting hole at the top of the support base and extends into the interior of the support base.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This facilitates the precise adjustment of geothermal pipes and allows visual inspection equipment to scan the interfaces on the pipes. The scanned signals drive a vacuum pump to evacuate the geothermal pipes. The conveying mechanism then transports the evacuated geothermal pipes to prepare for the next pipe's precise adjustment and evacuation, ensuring continuous processing and production.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example

[0027] like Figures 1 to 4 As shown, this embodiment provides a long cylindrical workpiece conveying mechanism, including two sets of transfer mechanisms 2 for conveying cylindrical workpieces 3. The transfer mechanism 2 includes a base 201. The upper surface of the base 201 is connected to a serrated top plate I203 through several equally spaced fixing frames 202. The two bases 201 are connected to a serrated top plate I205 adapted to the serrated top plate I203 through several equally spaced advancing parts 204 on the side that is close to each other. It should be noted that the top of the serrated top plate I203 and the serrated top plate I205 are toothed grooves for limiting the cylindrical workpiece 3.

[0028] In detail, the equidistant advancing section 204 includes several cylinders I2041 located on the top of the base 201. The right end of the cylinder I2041 is hinged to the base 201. The telescopic end on the left side of the cylinder I2041 is connected to a sliding member 2042 installed on the upper surface of the base 201. The equidistant advancing section 204 cooperates with the sawtooth top plate I203 to realize the conveying of the cylindrical workpiece 3.

[0029] A mounting plate 2043 is fixed to the top of the sliding member 2042. A hinge block I2046 is fixed to the top of the mounting plate 2043. A cylinder II2044 is hinged to the mounting plate 2043. A hinge rod 2045 is hinged to the telescopic end on the right side of the cylinder II2044. The hinge rod 2045 is hinged to the hinge block I2046. A hinge block I2047 is hinged to the end of the hinge rod 2045 away from the cylinder II2044. The top of the hinge block I2047 is fixed to the bottom of the connecting plate 2048. The connecting plate 2048 is fixed to the bottom of the sawtooth top plate I205.

[0030] Two adjustment mechanisms 1 are provided on both sides of the transition bracket 4 to cooperate with the two sets of transfer mechanisms 2. The adjustment mechanism 1 includes a drive part 11 and an adjustment part 12. It should be noted that the transition bracket 4 provides certain support for the excessively long cylindrical workpiece 3 (geothermal pipe) and can be set according to the actual situation.

[0031] The drive unit 11 includes a ground rail 111 and a slide plate 112 slidably mounted on the ground rail 111. A rack 114 is fixed to the inner wall of the ground rail 111. A servo motor 113 is mounted on the top of the slide plate 112. The output end of the servo motor 113 passes through the slide plate 112 and is fixed with a gear 115 that meshes with the rack 114.

[0032] The adjustment part 12 includes a support 121 mounted on the top of the slide plate 112. The top of the support 121 is equipped with a roller set for rotating and adjusting the cylindrical workpiece 3. The roller set consists of a roller 126 and a top-mounted conical roller 128.

[0033] In detail, the inner wall of the support base 121 is equipped with symmetrically arranged electric cylinders 1122 and 11123. The output ends of electric cylinders 1122 and 11123 penetrate through the upper surface of the support base 121 and are respectively connected to lifting plate 1124 and lifting plate 125. Guide rods 5 are fixed at the corners of the bottom surface of lifting plate 124 and lifting plate 125, and each guide rod 5 penetrates through the limiting hole at the top of the support base 121 and extends into the interior of the support base 121.

[0034] Two cooperating rollers 126 are installed on the top of the lifting plate 1124. One of the rollers 126 is driven by an asynchronous motor 127 installed on the side wall of the lifting plate 124. A top-mounted conical roller 128 is installed on the top of the lifting plate 125. The top-mounted conical roller 128 is driven by an asynchronous motor 129 installed on the side wall of the lifting plate 125. The support seat 121 is adjusted in position by the drive unit 11.

[0035] It should be noted that the servo motor 113, asynchronous motor I127 and asynchronous motor II129 are connected to the shafts of gear 115, roller 126 and top conical roller 128, and the hinge function is achieved at each hinge point through pins.

[0036] In this embodiment, the cylindrical workpiece conveying mechanism places the cylindrical workpiece 3 on two conveying mechanisms 2. The axial direction of the opposing conical roller 128 is perpendicular to the axial direction of the cylindrical workpiece 3. The opposing conical roller 128 in the two adjusting mechanisms 1 rotates to adjust the position of the cylindrical workpiece 3 on the conveying mechanism 2. After the cylindrical workpiece 3 is adjusted to the correct position on the two conveying mechanisms 2, the roller 126 rotates to drive the cylindrical workpiece 3 to rotate until the external visual inspection equipment detects the interface on the cylindrical workpiece 3 and stops, thus ensuring the vacuuming operation. Meanwhile, the driving part 11 in the adjusting mechanism 1 drives the adjusting part 12 to slide along the ground rail 111, thus moving multiple cylindrical workpieces 3. After each adjustment, once the cylindrical workpiece 3 is machined, cylinder I2044 pushes hinge rod 2045 to rotate along hinge block I2046, causing the end of hinge rod 2045 to lift connecting plate 2048. Then, cylinder I2041 drives sliding member 2042 to move to one side, thereby transferring multiple cylindrical workpieces 3. Cylinder I2041 then reverses hinge rod 2045, causing cylindrical workpiece 3 to be placed back on sawtooth top plate I203. When the height of sawtooth top plate I205 is lower than sawtooth top plate I203, cylinder I2041 pushes sliding member 2042 to move in the opposite direction, resetting connecting plate 2048 and preparing for the next transfer.

[0037] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
