Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, and in particular to a modular and detachable gantry crane main beam structure. Background Technology

[0002] The modular detachable gantry crane main beam structure is a new type of heavy machinery main beam that decomposes the traditional integral main beam into multiple standardized modules and assembles them through high-strength connectors.

[0003] The existing modular detachable gantry crane main beam structure decomposes the main beam into several standard modules, each of which can be designed and manufactured independently. This facilitates the use of standardized drawings and processes, reduces design complexity, and can be adapted to different spans without the need to redesign the overall structure.

[0004] However, in practical applications, the existing modular gantry crane main beam structure mostly uses bolts or pins to connect modules. During installation, each bolt needs to be tightened individually, resulting in low installation efficiency. Furthermore, the bolt tightening process requires repeated calibration, making the process cumbersome and extending the installation cycle, which is not conducive to improving the installation efficiency of the main beam module.

[0005] Therefore, this application provides a modular, detachable gantry crane main beam structure to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular, detachable gantry crane main beam structure.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a modular detachable gantry crane main beam structure, including a crane support, and further comprising:

[0008] A modular component is placed on top of a crane support. The modular component includes a main beam module set on top of the crane support. Both sides of the main beam module are connected to snap-fit ​​plates. Limiting grooves are formed on the snap-fit ​​plates. The main beam module is provided with snap-fit ​​grooves that match the snap-fit ​​plates and limiting grooves.

[0009] A reinforcement component is placed on the outside of the modular component and is used to further reinforce the main beam module. The reinforcement component includes a rigid snap-fit ​​member disposed on one side of the main beam module. The rigid snap-fit ​​member has a supporting inclined surface and is snapped into the main beam module through the supporting inclined surface.

[0010] Furthermore, the bottom of the main beam module is connected to a trolley slide rail.

[0011] The beneficial effect of adopting the above-mentioned further solution is that after the main beam modules are installed together, the trolley slide rails are connected, which facilitates the subsequent installation and movement of the trolley.

[0012] Furthermore, a support base is connected to the top of the main beam module, and the main beam module is connected to the crane bracket through the support base.

[0013] The advantages of adopting the above-mentioned further solution are: it facilitates the connection between the main beam module and the crane support, and can be connected to the main beam module at different positions, which helps to improve the flexibility of the connection between the crane support and the main beam module.

[0014] Furthermore, the snap-fit ​​plate is provided with an anti-slip coating.

[0015] The beneficial effect of adopting the above-mentioned further solution is that it makes the connection between the snap-fit ​​plate and the snap-fit ​​groove more secure, ensuring the stability of the main beam module after installation.

[0016] Furthermore, a fixing plate is connected to the snap-fit ​​plate, and the snap-fit ​​plate is snapped into the main beam module through the fixing plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when the snap-fit ​​plate is snapped into the inside of the snap-fit ​​groove, the fixing plate is snapped into the groove, which further improves the stability of the main beam module connection.

[0018] Furthermore, sliders are connected to both sides of the main beam module, and the rigid snap-fit ​​component is slidably connected to the main beam module through the sliders.

[0019] The beneficial effect of adopting the above-mentioned further solution is that it enables the rigid snap-fit ​​component to slide stably on the main beam module, which facilitates the movement of the rigid snap-fit ​​component to the interface after the main beam module is connected.

[0020] Furthermore, the rigid connector is provided with a pin on the main beam module.

[0021] The beneficial effect of adopting the above-mentioned further solution is that it improves the support and rigidity of the connection between the pin shaft and the main beam module, which is conducive to fixing the rigid snap-fit ​​parts to the main beam module.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. By setting up modular components, snap-fit ​​plates are symmetrically welded to both ends of the main beam module, and the snap-fit ​​grooves are adapted to the shape of the snap-fit ​​plates. When it is necessary to splice the main beam modules, the snap-fit ​​plate of the previous main beam module is pushed into the snap-fit ​​groove of the next main beam module to complete the initial fixation. The limiting block welded inside the snap-fit ​​groove matches the limiting groove, so that the snap-fit ​​plate and the limiting groove form a mechanical engagement in the snap-fit ​​groove. The snap-fit ​​plate and the main beam module are set in the same direction, while the limiting groove is perpendicular to the main beam module. Together, they form a bidirectional limiting quick snap-fit ​​structure, ensuring that the main beam module and the snap-fit ​​plate are firmly connected. This solves the problem of low installation efficiency, reduces the dependence on bolts, and improves the installation speed of the crane support.

[0024] 2. By setting up reinforcement components, after the main beam module is installed, the rigid snap-fit ​​parts are pushed to the joint between the two main beam modules. The rigid snap-fit ​​parts are equipped with support slopes that are compatible with the main beam modules. When the rigid snap-fit ​​parts are in place, their own structure, together with the support slopes, can securely fix the main beam modules from the outside. Through additional reinforcement, the connection between the main beam modules is further strengthened, the overall stability of the modular detachable gantry crane main beam structure is improved, and the structure is ensured to be firm and reliable during use.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-5 As shown, this utility model provides a technical solution: a modular detachable gantry crane main beam structure, including a crane support 1, and further comprising:

[0036] like Figures 1-3 As shown, modular component 2 is placed on top of crane support 1. Modular component 2 includes main beam module 21 set on top of crane support 1. Both sides of main beam module 21 are connected to snap-fit ​​plates 22. Limiting grooves 23 are opened on snap-fit ​​plates 22. Snap-fit ​​grooves 24 that match snap-fit ​​plates 22 and limiting grooves 23 are opened on main beam module 21.

[0037] like Figures 1-4As shown, reinforcement component 3 is placed outside modular component 2 and used to further reinforce main beam module 21. Reinforcement component 3 includes a rigid snap-fit ​​component 31 disposed on one side of main beam module 21. The rigid snap-fit ​​component 31 has a supporting inclined surface 32. The rigid snap-fit ​​component 31 snaps into main beam module 21 through the supporting inclined surface 32. The snap-fit ​​plate 22 is welded to both ends of main beam module 21 and mirrored along the horizontal plane. The snap-fit ​​groove 24 matches the snap-fit ​​plate 22 on the far side. When main beam modules 21 need to be spliced, the previous main beam module 21 is pushed to snap into the snap-fit ​​groove 24 on the next main beam module 21 through the snap-fit ​​plate 22 on it for fixation. A limiting block matching the limiting groove 23 is welded inside the snap-fit ​​groove 24, so that the limiting groove 23 and the snap-fit ​​plate 22 cooperate to form a tight mechanical engagement inside the snap-fit ​​groove 24. The direction of the connecting plate 22 is consistent with that of the main beam module 21, and the direction of the limiting groove 23 is perpendicular to that of the main beam module 21. The two work together to form a bidirectional limiting quick snap-fit, thereby ensuring a stable connection between the main beam module 21 and the snap-fit ​​plate 22. This solves the problem of low installation efficiency caused by the need to tighten bolts one by one during the installation process when connecting modules with bolts or pins 34. It reduces bolt dependence, makes installation faster, and helps to improve the installation speed of the crane bracket 1. After the main beam module 21 is installed, the rigid snap-fit ​​piece 31 is pushed to the connection point of the two main beam modules 21. Since the rigid snap-fit ​​piece 31 has a matching support slope 32 for the main beam module 21, the support slope 32 and the rigid snap-fit ​​piece 31 work together to fix the main beam module 21 from the outside, thereby further strengthening the connection of the main beam module 21 and improving the stability of the modular detachable gantry crane main beam structure.

[0038] Furthermore, such as Figure 2 As shown, the bottom of the main beam module 21 is connected to the trolley slide rail 26. By welding the trolley slide rail 26 to the bottom of the main beam module 21, the trolley slide rail 26 and the main beam module 21 are modularized together. When the main beam module 21 is installed together, the trolley slide rail 26 is connected, which facilitates the subsequent installation and movement of the trolley.

[0039] Furthermore, such as Figure 2 As shown, a support seat 28 is connected to the top of the main beam module 21. The main beam module 21 is connected to the crane bracket 1 through the support seat 28. By installing the support seat 28 in the middle of the main beam module 21 and using flange plates and bolts to install the support seat 28 on the crane bracket 1, it is convenient to connect the main beam module 21 and the crane bracket 1, and it can be connected to the main beam module 21 in different positions, which helps to improve the flexibility of the connection between the crane bracket 1 and the main beam module 21.

[0040] Furthermore, such as Figure 3As shown, the snap-fit ​​plate 22 is provided with an anti-slip coating 25. By spraying the anti-slip coating 25 onto the snap-fit ​​plate 22, the anti-slip coating 25 increases the friction between the snap-fit ​​plate 22 and the snap-fit ​​groove 24, making the snap-fit ​​plate 22 and the snap-fit ​​groove 24 more firmly connected, and ensuring the stability of the main beam module 21 after installation.

[0041] Furthermore, such as Figure 3 As shown, a fixing plate 27 is connected to the snap-fit ​​plate 22. The snap-fit ​​plate 22 is snapped into the main beam module 21 through the fixing plate 27. By opening a slot on the main beam module 21 that matches the fixing plate 27, when the snap-fit ​​plate 22 is snapped into the inside of the snap-fit ​​slot 24, the fixing plate 27 is snapped into the slot, which further improves the stability of the main beam module 21 during connection.

[0042] Furthermore, such as Figure 3 As shown, sliders 33 are connected to both sides of the main beam module 21. The rigid snap-fit ​​component 31 is slidably connected to the main beam module 21 through the sliders 33. By welding the sliders 33 onto the main beam module 21, the rigid snap-fit ​​component 31 is installed on the sliders 33 before splicing the main beam module 21, so that the rigid snap-fit ​​component 31 can slide stably on the main beam module 21, which is convenient for moving the rigid snap-fit ​​component 31 to the interface after the main beam module 21 is connected.

[0043] Furthermore, such as Figure 4 As shown, the rigid snap-fit ​​connector 31 and the main beam module 21 are provided with pins 34. By installing a flange on the rigid snap-fit ​​connector 31 through the groove on the main beam module 21 and the snap-fit ​​plate 22 that matches the pin 34, the pin 34 is then installed on the rigid snap-fit ​​connector 31, thereby improving the support and rigid connection between the pin 34 and the main beam module 21, which is beneficial for fixing the rigid snap-fit ​​connector 31 and the main beam module 21.

[0044] Working principle: such as Figures 1-5As shown, the rigid snap-fit ​​component 31 is first installed on the slider 33, allowing the rigid snap-fit ​​component 31 to slide on the main beam module 21. One main beam module 21 is then lifted onto the assembly platform. Subsequent main beam modules 21 are pushed from above to one side of this main beam module 21, causing the snap-fit ​​plates 22 on the two main beam modules 21 to snap into each other with the snap-fit ​​grooves 24. At this time, the limiting groove 23 snaps into the limiting groove 23 inside the snap-fit ​​groove 24, and the fixing plate 27 snaps into the groove of the main beam module 21. This allows the limiting groove 23 and the snap-fit ​​plate 22 to form a tight mechanical engagement inside the snap-fit ​​groove 24. The two work together to form a bidirectional limiting quick snap-fit. Maintaining a stable connection between the main beam module 21 and the snap-fit ​​plate 22 helps to improve the installation speed of the main beam module 21. At the same time, the anti-slip coating 25 increases the friction between the snap-fit ​​plate 22 and the snap-fit ​​groove 24, making the connection between the snap-fit ​​plate 22 and the snap-fit ​​groove 24 more secure. Then, the rigid snap-fit ​​member 31 is pushed to the connection point of the main beam module 21. Since the rigid snap-fit ​​member 31 has a supporting inclined surface 32, it supports the main beam module 21 from the bottom, thereby strengthening the connection of the rigid snap-fit ​​member 31 from multiple directions, which further strengthens the connection of the main beam module 21 and helps to improve the stability of the main beam structure of the modular detachable gantry crane.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
