Technical Field

[0001] This utility model relates to the field of automation, and in particular to a truss with a fall-holding mechanism. Background Technology

[0002] With continuous industrial advancements and the increasing prevalence of automated production lines, more and more robots have entered most factories. Gantry robots are widely used in the machinery manufacturing field, characterized by high precision, high speed, and accurate positioning. Gantry robots are equipped with sliding platforms that can move up and down, on which booms or other working parts are mounted. However, during gantry maintenance or repair, existing gantry robots lack safety limit mechanisms, or the platform may descend rapidly during operation, causing it to fall and potentially damaging products or even resulting in personal injury or death. Utility Model Content

[0003] The technical problem to be solved by this utility model is that existing trusses lack anti-fall devices, which can easily cause falling accidents. This utility model provides a truss with a fall-holding mechanism to solve the above problem.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0017] Any process or method described in the flowchart or otherwise herein can be understood as representing a module, segment, or portion of code comprising one or more executable instructions for implementing a particular logical function or process, and the scope of the preferred embodiments of the present invention includes additional implementations in which functions may be performed not in the order shown or discussed, including substantially simultaneously or in reverse order according to the functions involved, as should be understood by those skilled in the art to which embodiments of the present invention pertain.

[0018] like Figures 1 to 5 As shown, this utility model provides a truss with a fall-holding mechanism, including a base 1, a turntable 2 rotatably mounted on the base 1, and a column 3 mounted on the turntable 2. A slide table 4 is slidably mounted on the column 3, a slide rail 5 is vertically fixedly mounted on the column 3, a slider 6 is slidably mounted on the slide rail 5, and the slide table 4 is fixedly mounted on the slider 6. A rack 7 is also fixedly mounted on the column 3, and the rack 7 is arranged parallel to the slide rail 5. A lifting motor 8 is fixedly mounted on the slide table 4, and a lifting gear 9 is mounted on the output shaft of the lifting motor 8. The lifting gear 9 meshes with the rack 7. A braking mechanism 10 is mounted on the slide table 4. The braking mechanism 10 includes a brake 11 and a brake gear 12 disposed at the rotating end of the brake 11. The brake gear 12 meshes with the rack 7.

[0019] Trusses are a common type of lifting machinery in factories, mostly used for transferring goods. The truss described in this application has a lifting boom and lifting devices mounted on a slide 4. The slide 4 rises and falls on the column 3 to adjust the height of the boom, thereby enabling the transfer and handling of goods.

[0020] In actual use, the slide table 4 is fixed on the slider 6, and the slider 6 is slidably mounted on the slide rail 5. The slide table 4 can slide up and down along the column 3. When it is necessary to adjust the height, the lifting motor 8 works and drives the lifting gear 9 to rotate. The lifting gear 9 will roll up and down along the meshing rack 7 to drive the slide table 4 to adjust the height.

[0021] During normal operation, the brake 11 is in the released state, meaning that the brake gear 12 can rotate along the rack 7 without affecting the lifting and lowering action of the slide 4. In case of an accident, when the slide 4 falls out of control, the lifting motor 8 detects the out-of-control state and can lock the brake. At the same time, it sends a signal to control the brake 11 to switch states. The brake 11 immediately switches from the normal released state to the brake-locked state, and the brake gear 12 will be in the locked braking state. This can prevent the slide 4 from falling and achieve the anti-fall function.

[0022] Simply relying on the brake of the lifting motor 8 is not enough to prevent the large mass slide 4 from falling. Therefore, the braking mechanism 10 locks the slide 4 immediately after receiving the runaway signal from the lifting motor 8, which can ensure that the slide 4 is reliably and timely held in place, thus improving the reliability of the truss operation.

[0023] A rotary gear 13 is provided on the base 1, and the turntable 2 is rotatably mounted on the rotary gear 13 via a rotary bearing. A rotary motor 14 is provided on the turntable 2, and a displacement gear 15 is mounted on the output shaft of the rotary motor 14. The displacement gear 15 meshes with the rotary gear 13.

[0024] Turntable 2 can rotate on rotary gear 13. By driving displacement gear 15 to rotate through rotary motor 14, turntable 2 can rotate and change position around rotary gear 13. This allows for the rotation and adjustment of the boom and cargo on slide table 4. The rotation and displacement position is controllable and the rotation is smooth. The overall structural strength and rigidity of the truss are high.

[0025] The turntable 2 is equipped with a slewing support wheel 16, which meshes with the slewing gear 13; the slide table 4 is equipped with a lifting support wheel 17, which meshes with the rack 7. The slewing support wheel 16 ensures the stability and reliability of the turntable 2 during rotation, improving the structural strength of the rotation, while the lifting support wheel 17 ensures that the slide table 4 has sufficient structural strength during lifting, increasing the overall reliability of the truss.

[0026] The brake 11 is a pneumatic brake. Pneumatic brakes are easy to control and have a fast response speed, enabling rapid braking while providing strong locking capability and high equipment reliability.
