[0005] By adopting the above technical solution, the forward and reverse rotation of the output shaft of the drive motor can drive the sliding seat to slide back and forth along the guide rail, thereby realizing the linear motion of the load module. By adopting the gear and rack transmission method, the load capacity of the load module is improved.

[0011] By adopting the above technical solution and setting sensors to control the sliding of the sliding seat, the sliding seat is prevented from hitting the mounting plate when sliding at high speed or under heavy load, thereby improving the safety and practicality of the load module.
[0012] Preferably, a plurality of anti-collision rubbers are fixedly connected to the load-bearing beam, the anti-collision rubbers being used to prevent the sliding seat from impacting the mounting plate.
[0013] By adopting the above technical solution, the impact of the sliding seat on the mounting plate during high-speed sliding or heavy-load movement is further avoided, thereby improving the safety and practicality of the load module.
[0014] Preferably, the sliding seat is a separate unit, comprising a top plate, a side plate, and a bottom plate.
[0015] By adopting the above technical solution, the split design makes the sliding seat easier to assemble and maintain, thus improving the practicality of the load module.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] 1. The forward and reverse rotation of the output shaft of the drive motor can drive the sliding seat to slide back and forth along the guide rail, thereby realizing the linear motion of the load module. By adopting a gear and rack transmission method, the load capacity of the load module is improved. At the same time, the cross-section of the load beam is square, which has high strength and further improves the load capacity of the load module.
[0018] 2. The meshing method of helical gears and helical racks improves the load capacity of the load module, while making the load distribution of the teeth more uniform under heavy load, reducing local wear and improving the service life of the load module.
[0019] 3. By setting sensors to control the sliding of the sliding base, the impact of the sliding base on the mounting plate during high-speed sliding or heavy-load movement is avoided, thereby improving the safety and practicality of the load module. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] Reference Figure 1 and Figure 3 The square gear rack heavy-duty module includes a load-bearing beam 1, a guide rail 2 fixedly connected to the load-bearing beam 1, a sliding seat 3 slidably connected to the guide rail 2, and a drive assembly 4 for driving the sliding seat 3 to slide along the guide rail 2. The drive assembly 4 includes a rack 41 fixedly connected to the load-bearing beam 1, a drive motor 42 fixedly connected to the sliding seat 3, and a gear 43 fixedly connected to the output shaft of the drive motor 42. The gear 43 meshes with the rack 41. The load-bearing beam 1 has a square cross-section and a hollow inner cavity. The square shape of the load-bearing beam 1 helps to improve the load-bearing capacity, while the hollow shape reduces the overall weight of the module. Mounting plates 5 are also fixedly connected to both sides of the load-bearing beam 1. In this embodiment, the mounting plates 5 and the load-bearing beam 1 are fixedly connected by bolts. The forward and reverse rotation of the output shaft of the drive motor 42 can drive the sliding seat 3 to slide back and forth along the guide rail 2, thereby realizing the linear motion of the load module. By adopting the transmission method of helical gear and helical rack, the load capacity of the load module is improved. At the same time, the cross section of the load beam 1 is set in a square shape, which has high strength and further improves the load capacity of the load module.
[0026] In addition, the sliding base 3 is a split design, including a top plate 31, a side plate 32, and a bottom plate 33. The top plate 31, side plate 32, and bottom plate 33 are fixedly connected by bolts. This design facilitates disassembly and replacement of corresponding parts during maintenance. The split design makes the sliding base 3 easy to assemble and maintain, improving the practicality of the load module.
[0027] Reference Figure 1 and Figure 2There are two guide rails 2, which are respectively set on opposite sides of the load-bearing beam 1 and are arranged in parallel. In order to reduce the friction when the sliding seat 3 slides, two sliders 9 are fixedly connected to the two side plates 32 respectively. The sliders 9 are slidably connected to the guide rail 2 on the corresponding side. The two guide rails 2 and the two sliders 9 can improve the overall load capacity and improve the stability of the sliding seat 3 when it slides.
[0028] To further improve the load capacity of the load module, gear 43 is a helical gear, and rack 41 is a helical rack that matches gear 43. The meshing method of helical gear and helical rack improves the load capacity of the load module, while making the load distribution of the teeth of the linear module more uniform under heavy load, reducing local wear, and improving the service life of the load module.
[0029] To improve the safety of the load module, several sensors 6 are fixedly connected to the load-bearing beam 1, and sensing plates 7 are fixedly connected to the sliding seat 3. The sensors 6 are electrically connected to the drive motor 42. In this embodiment, there are two sensors 6, which are respectively located near both ends of the load-bearing beam 1. When the sensing plate 7 triggers the sensor 6, the sensor 6 sends an electrical signal to control the drive motor 42 to stop rotating. By setting the sensors 6 to control the sliding of the sliding seat 3, collisions with the mounting plate 5 are avoided when the sliding seat 3 slides at high speed or moves under heavy load, thus improving the safety and practicality of the load module.
[0030] Several anti-collision rubber pads 8 are fixedly connected to the load-bearing beam 1. The anti-collision rubber pads 8 are used to prevent the sliding seat 3 from impacting the mounting plate 5. In this embodiment, there are four anti-collision rubber pads 8, which are arranged in pairs near both ends of the load-bearing beam 1. This further avoids the sliding seat 3 from impacting the mounting plate 5 when sliding at high speed or under heavy load, thus improving the safety and practicality of the load module.
[0031] The implementation principle of the square tube gear rack heavy load module of this application is as follows: by controlling the drive motor 42 to rotate, the gear 43 is driven to rotate. The gear 43 and the rack 41 mesh, thereby causing the sliding seat 3 to slide along the guide rail 2, thus realizing the linear sliding function of the load module. The setting of helical gear, helical rack and double guide rail improves the load capacity of the load module. At the same time, the sensor 6 and anti-collision rubber 8 are set to improve the safety and practicality of the load module.
[0032] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
