Description

Technical Field

[0001] This utility model belongs to the field of assembly tooling technology, and in particular relates to a tooling for assembling an annular shell type conveyor structure. Background Technology

[0002] The annular shell conveyor structure was designed and developed by observing the structure and operating principle of a snail shell. This type of conveyor structure, resembling a snail shell, is a specialized device designed primarily for logistics transportation and large-scale power generation projects such as water conservancy projects. Traditional annular shell conveyor structures typically have a fixed pitch, while innovative designs may employ variable pitch technology, where the helical pitch of the annular shell conveyor gradually changes from the inlet to the outlet. This design can better adapt to different flow conditions and improve conveying performance under various operating conditions, but it also increases the difficulty of design and assembly.

[0003] Existing annular shell conveyor structures typically use low-alloy high-strength structural steel. These structures are usually composed of multiple arc-shaped plates, welded or bolted together to form a robust, snail-shell-like structure. An internal spiral channel is designed with a small inlet and a large outlet, utilizing centrifugal force to increase conveying efficiency. However, because annular shell conveyors are irregularly shaped and require high assembly precision, the assembly process must not only ensure the plates are aligned correctly but also prevent deformation during assembly. Current tooling still suffers from poor structural stability, hindering the improvement of assembly accuracy. Utility Model Content

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] A tooling for assembling an annular shell type conveyor structure, such as Figures 1 to 4 As shown, it includes a substrate 1, an outer support mechanism, and an inner support mechanism.

[0030] The aforementioned substrate 1 is provided with a positioning member 2 for positioning the plate. For example, the positioning member 2 can be installed and fixed on the substrate 1 by conventional methods such as screws or welding, and is used to hold and limit the bottom end of the plate, so as to ensure that the plate on the substrate 1 remains stable during the subsequent plate assembly process.

[0031] The aforementioned external support mechanism includes an external support member 3, one end of which is disposed on the substrate 1, and the other end is provided with a positioning part for positioning the plate. For example, the external support member 3 can also be installed and fixed on the substrate 1 by conventional methods such as screws or welding, to support and limit the outer side of the plate, and cooperate with the positioning member 2 to realize the inner and outer limiting of the first substrate 1, thereby helping to further improve the assembly accuracy of subsequent plates.

[0032] The aforementioned internal support mechanism includes a connector 13, an intermediate component 5, a support tie beam 4, and a limiting tie beam 6. Multiple support tie beams 4 are arranged radially around the intermediate component 5. Each support tie beam 4 has one end connected to the intermediate component 5 and the other end equipped with a connector 13 for positioning the plate. The limiting tie beam 6 has connectors 13 for positioning the plate at both its left and right ends. A tie rod 7 is located in the middle of the limiting tie beam 6. The tie rod 7 is perpendicular to the limiting tie beam 6, with one end connected to the limiting tie beam and the other end equipped with a connector 13 for positioning the plate.

[0033] For example, the support tie beams 4 can be arranged radially in three, four, five, or more as needed, and the corresponding intermediate parts 5 also have multiple mounting positions for the support tie beams 4, so that operators can select the appropriate position to install the support tie beams 4 according to actual needs. Among them, the limiting tie beams 6 can be used as auxiliary connections to further limit small plates or plates with small curvature, preventing small plates from deforming or moving during assembly.

[0034] In practical applications, tie rod 7 is fixed to limiting tie beam 6. The limiting tie beam 6 and tie rod 7 form a stable T-shaped structure, which is used to limit and fix the middle and left and right ends of the small plate, preventing deformation of the small plate. At the same time, by using the supporting tie beam 4 to connect the small plate, the alignment and positioning of the small plate and the large plate can be achieved, ensuring the accuracy of subsequent welding and assembly.

[0035] Preferably, the support beam 4 is connected to the intermediate component 5 via connecting bolts 12. The intermediate component 5 has mounting holes 11 that mate with the connecting bolts 12, and multiple mounting holes 11 are evenly distributed along the circumference of the intermediate component 5. For example, the support beam 4 has bolt holes that mate with the connecting bolts 12. By using connecting bolts 12 to connect the intermediate component 5 and the support beam 4, the operation is simple, reducing the assembly difficulty of the support beam 4. Furthermore, to improve the connection strength, two connecting bolts 12 can also be provided on each support beam 4.

[0036] In practical applications, the support beam 4 is provided with an assembly groove that mates with the intermediate component 5, and the connecting bolt 12 is provided corresponding to the assembly groove. By providing an assembly groove on the support beam 4 and utilizing the assembly groove to mate with the intermediate component 5, the structural strength at the connection between the support beam 4 and the intermediate component 5 is improved.

[0037] Preferably, the inner support mechanism further includes a telescopic strut 8, the end of which is provided with a universal ball joint 9. The upper and lower parts of the intermediate component 5 are provided with arc-shaped grooves 10 that can mate with the universal ball joint 9. For example, the telescopic strut 8 can be a commonly used telescopic strut, such as a threaded telescopic strut. Those skilled in the art can choose according to actual needs, and this will not be elaborated further here. The universal ball joint 9 can be installed at the end of the telescopic strut 8 by conventional methods such as welding or screws. In actual use, the length of the telescopic strut 8 can be adjusted, and the universal ball joint 9 can mate with the upper and lower intermediate components 5 to support the upper and lower sets of intermediate components 5, thereby connecting multiple sets of inner support mechanisms, improving the overall stability of the inner support mechanism, and ensuring that the inner support mechanism can continuously and stably support and position the plate.

[0038] Preferably, one end of the connector 13 is threadedly connected to the corresponding support beam 4, limiting beam 6, or tie rod 7, and the other end is provided with a fitting part 16 that can adhere to the surface of the plate. The fitting part 16 is rotatably mounted on the connector 13. For example, the connector 13 can be connected to the plate by conventional methods such as welding or screws to ensure that the support beam 4, limiting beam 6, and tie rod 7 can position the plate.

[0039] In practical applications, the connector 13 has a ball-head part 15 at one end and an external thread at the other end. The fitting part 16 has a mounting hole that fits with the connector 13 with a clearance, and an arc groove that fits with the ball-head part 15. The arc groove communicates with the mounting hole. For example, the ball-head part 15 is fixed on the connector 13. The fitting part 16 includes a fitting plate that fits with the surface of the board and a sleeve. The mounting hole and the arc groove are both provided on the sleeve. The fitting plate and the sleeve can be connected by conventional methods such as screws or welding.

[0040] By providing mounting holes on the bonding component 16 that fit with the connector 13 with clearance, and by utilizing the ball head 15 on the connector 13 to engage with the arc groove on the bonding component 16, the bonding component 16 can be rotated and adjusted adaptively. This ensures that when the operator rotates and adjusts the connector 13 to adjust the overall length of the support beam 4, the limiting beam 6, or the tie rod 7, the bonding component 16 can always stably connect the sheet metal.

[0041] Preferably, the end of the connector 13 extending out of the mounting hole is provided with a clamping part 14 for easy screwing. For example, the clamping part 14 can be a clamping groove, so that the operator can use a wrench or other tools to screw the connector 13. By using the external thread on the connector 13 to cooperate with the threaded groove on the corresponding support beam 4, limit beam 6 or tie rod 7, the extension length of the connector 13 can be adjusted, thereby adjusting the overall length of the support beam 4, limit beam 6 or tie rod 7. The operation is very simple.

[0042] The tooling for assembling annular shell conveyor structures described in this utility model has the advantages of simple structure, easy assembly and use, and is applicable to the assembly of annular shell conveyor structures, and helps to improve the assembly accuracy of annular shell conveyor structures. By setting positioning parts, external support mechanisms and internal support mechanisms on the base, positioning and limiting of various plates can be realized, ensuring that the plates are not easily deformed or moved during the assembly process, and ensuring the accuracy of subsequent welding and assembly.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
