Description

Technical Field

[0001] This utility model relates to the technical field of graphite tube transfer devices, and in particular to a graphite tube transport tool for heat exchangers. Background Technology

[0002] Graphite tubes are a crucial component of graphite heat exchangers. The excellent thermal conductivity of graphite allows heat to be rapidly transferred from the tube wall to the fluid. Furthermore, graphite tubes possess excellent corrosion resistance, enabling them to handle various corrosive media. During the production of graphite heat exchangers, the transfer of graphite tubes between workshops and warehouses is frequently necessary. Currently, this is typically done using hand-pulled carts, which lack a securing device, allowing the tubes to easily roll and potentially damage them during transport. To address this issue, this application proposes a graphite tube transport tool for heat exchangers. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technology, this utility model provides a graphite tube transport tool for heat exchangers. The technical solution it provides includes a base plate. The base plate has a walking device at its lower end, multiple sets of longitudinally arranged support components at its upper end, multiple longitudinally evenly distributed vertical rods fixedly connected to the base plate, a longitudinal axis fixedly connected to each vertical rod, and a drive rod rotatably connected to each vertical rod and arranged parallel to the longitudinal axis. The drive rod drives multiple sets of longitudinally evenly distributed clamping devices, each clamping device corresponding to and cooperating with one of the support components. A worm gear is coaxially fixedly connected to the front end of the drive rod, and an installation rod is fixedly connected to the front end of the base plate. A worm gear cooperating with the worm gear is rotatably connected to the installation rod.

[0004] Each set of support components includes two support blocks arranged symmetrically about the longitudinal axis and fixedly connected to the base plate, and the support blocks are provided with V-shaped grooves;

[0005] Each clamping device includes a threaded portion integrally arranged with the drive rod. The threaded portion is composed of two screw portions with opposite thread directions. The two screw portions are respectively threadedly connected to clamping rods that are slidably connected to the longitudinal axis. Each clamping rod is fixedly connected to an arc-shaped clamping plate.

[0006] Preferably, the right end of the worm gear extends out of the mounting rod and is coaxially and fixedly connected to a handwheel.

[0007] Preferably, each of the arc-shaped clamps has an anti-slip pad fixedly connected to its inner edge surface.

[0008] Preferably, the walking device includes four omnidirectional wheels arranged in a rectangular array and installed at the lower end of the base plate. A pull rod is fixedly connected to the middle of the left end of the base plate, and a handrail is fixedly connected to the upper end of the pull rod.

[0009] The beneficial effects of this utility model are:

[0010] This application provides stable support for graphite tubes via support blocks in its support components. The V-shaped grooves on the support blocks initially limit the position of the graphite tubes, ensuring stable placement. Furthermore, this application includes a clamping device that works in conjunction with the support components. This clamping device uses arc-shaped clamps to clamp and secure the graphite tubes placed on the support components, further limiting their position. This ensures the stability of the graphite tubes during transport, preventing them from rolling due to unexpected factors and thus avoiding damage. This application features a simple structure, ease of use, and strong practicality. Moreover, the base plate of this application is equipped with multiple sets of support components and clamping devices that work with them, facilitating the simultaneous transport of multiple graphite tubes and improving transport efficiency.

[0017] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0018] In Embodiment 1, the technical solution is as follows: the support block 10 of the support component 2 can stably support the graphite tube 21. The V-shaped groove 11 on the support block 10 can initially limit the position of the graphite tube 21, ensuring its stable placement. Furthermore, the present application also provides a clamping device 6 that works in conjunction with the support component 2. The clamping device 6 can clamp and fix the graphite tube 21 placed on the support component 2 through the arc-shaped clamping plate 15, further limiting the position of the graphite tube 21. This ensures the stability of the graphite tube 21 during transportation, preventing it from rolling due to unexpected factors and thus avoiding damage. The present application has a simple structure, is easy to use, and is highly practical. Moreover, the base plate 1 of the present application is arranged with multiple sets of support components 2 and clamping devices 6 that work in conjunction with the support components 2, which facilitates the simultaneous transportation of multiple graphite tubes 21 and improves transportation efficiency.

[0019] In Example 2, based on Example 1, to avoid interference between the arc-shaped clamp 15 and the placement of the graphite tube 21 during use, the worm gear 9 on the mounting rod 8 should be rotated counterclockwise first. A handwheel 16 is provided to facilitate the rotation of the worm gear 9. The counterclockwise rotation of the worm gear 9 will drive the drive rod 5 to rotate around the vertical rod 3 via the worm wheel 7. The rotation of the drive rod 5 will cause the threaded portion 12 on it to rotate accordingly, thereby synchronizing the operation of each set of clamping devices 6. Specifically, the threaded portion 12 of each set of clamping devices 6 includes two... When the screw part 12 rotates, the two screw parts 13 with opposite screw directions will drive the two clamping rods 14 of the clamping device 6, causing the two clamping rods 14 of the clamping device 6 to move away from each other along the longitudinal axis 4. Consequently, the two arc-shaped clamping plates 15 corresponding to the clamping rods 14 will also move away from each other until the distance between the two arc-shaped clamping plates 15 is convenient for placing the graphite tube 21, at which point the rotation of the worm gear 9 can be stopped. At this time, the graphite tube 21 can be placed in the V-shaped bracket 11 on the support block 10.

[0020] As described above, after placing the graphite tube 21 on the support assembly 2, the worm gear 9 is rotated clockwise to further fix the graphite tube 21 through the arc-shaped clamping plate 15 of the clamping device 6. The clockwise rotation of the worm gear 9 will drive the drive rod 5 to rotate synchronously through the worm wheel 7. When the drive rod 5 rotates, the threaded part 12 on it will also rotate synchronously. Consequently, the two clamping rods 14 of each clamping device 6 will also move closer to each other along the longitudinal axis 4 under the drive of the threaded part 12. Consequently, the arc-shaped clamping plates 15 corresponding to the two clamping rods 14 will also move closer to each other. Consequently, the two arc-shaped clamping plates 15 will clamp the graphite tube 21 on both sides of the outer edge. Furthermore, the inner edge of the arc-shaped clamping plate 15 is provided with an anti-slip pad 17, which can increase the friction between the arc-shaped clamping plate 15 and the graphite tube 21, further ensuring the stability of the graphite tube 21 during transportation. This application provides power to the clamping device 6 through the cooperation of worm 9 and worm wheel 7. The worm 9 and worm wheel have self-locking properties, which can help ensure the stability of related components and prevent them from moving due to unexpected factors during transportation.

[0021] In embodiment three, based on embodiment two, this application also includes a walking device. The universal wheels 18 of the walking device facilitate flexible reversal during transport, and the pull rod 19, together with the handrail 20, facilitates the pulling and transport of this application.
