The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] It is understandable that, referring to Figure 1 and Figure 2 The symmetrical gantry of the present invention includes a frame 100, two support frames 200 and a reinforcement mechanism 300. The two support frames 200 are symmetrically arranged on the frame 100. The two support frames 200 are fixedly connected to the opposite sides with a cross arm 210, and the cross arm 210 is used to install the manipulator 400; the reinforcement mechanism 300 includes a connecting rod 310 and a diagonal brace rod 320. The two ends of the connecting rod 310 are respectively fixedly connected to the support frame 200 and the cross arm 210. The diagonal brace rod 320 is arranged on the side of the support frame 200 away from the cross arm 210, and the two ends of the diagonal brace rod 320 are respectively fixedly connected to the frame 100 and the support frame 200. A support plate 330 is provided between the support frame 200 and the diagonal brace rod 320, and the support frame 200 and the diagonal brace rod 320 are both in contact with the support plate 330.

[0031] The two support frames 200 are symmetrically arranged on both sides of the frame 100. The two sides of the support frames 200 facing each other are fixedly connected to the cross arms 210, and the manipulator 400 is fixedly mounted on the cross arms 210. The two ends of the connecting rod 310 are respectively fixedly connected to the support frames 200 and the cross arms 210. The connecting rod 310 can improve the connection strength between the support frames 200 and the cross arms 210, so that the cross arms 210 can be stabilized on the support frames 200, reduce the deformation of the cross arms 210, and improve the stability of the manipulator 400. The diagonal brace 320 is arranged on the side of the support frames 200 away from the cross arms 210, and the two ends of the diagonal brace 320 are respectively fixedly connected to the frame 100 and the support frames 200 to improve the connection strength between the frame 100 and the support frames 200, so that the support frames 200 can be stabilized on the frame 100, reduce the deformation of the support frames 200, and improve the stability of the manipulator 400. The support plate 330 is arranged between the support frame 200 and the diagonal support rod 320. By setting the support plate 330 to abut against the support frame 200 and the diagonal support rod 320, the force applied to the support frame 200 can be smoothly transmitted to the diagonal support rod 320, thereby improving the stability of the force and enhancing reliability.

[0032] It should be noted that the frame 100 and the support frame 200, the support frame 200 and the cross arm 210, the connecting rod 310 and the support frame 200 and the cross arm 210, and the diagonal support rod 320 and the frame 100 and the support frame 200 are all fixed together by welding, and can also be connected together by fasteners to increase the connection strength and enhance the reliability of the symmetrical gantry.

[0033] It is understandable that, referring to Figure 3 and Figure 5 The connecting rod 310 is arranged below the cross arm 210 so that the connecting rod 310 can support the weight of the cross arm 210 and the manipulator 400, and can reduce the influence of the deadweight of the connecting rod 310 on the connection, can reduce the length of the connecting rod 310, and reduce the possibility of bending and deformation of the connecting rod 310, so that the cross arm 210 can be stabilized on the support frame 200, thereby improving reliability.

[0034] In addition, by arranging the connecting rod 310 below the cross arm 210, the height of the support frame 200 can be reduced, thereby improving the ability of the support frame 200 to resist bending deformation and improving the reliability of the gantry.

[0035] It is understandable that, referring to Figure 5 and Figure 6 The number of support plates 330 is set to two, and the two support plates 330 are arranged in parallel. A plurality of cross plates 331 are fixedly connected between the two support plates 330, and the cross plates 331 are arranged at intervals. By setting the number of support plates 330 to two, the connection strength between the support frame 200 and the diagonal brace 320 is improved, so that the force applied to the support frame 200 can be smoothly transmitted to the diagonal brace 320, thereby improving the load-bearing capacity of the support frame 200 and enhancing the support stability of the support frame 200.

[0036] Among them, multiple cross plates 331 are arranged at intervals between the two support plates 330. By setting the cross plates 331, the two support plates 330 can be connected together, thereby improving the connection stability of the two support plates 330. The cross plates 331 can also improve the bending resistance of the support frame 200, thereby reducing the deformation of the support frame 200 and improving the reliability of the symmetrical gantry.

[0037] It is understandable that, referring to Figure 3 and Figure 4 The cross arm 210 includes a first mounting rod 211 and two second mounting rods 212. The two second mounting rods 212 are respectively fixedly connected to the two ends of the first mounting rod 211. The ends of the second mounting rods 212 facing away from the first mounting rod 211 are fixedly connected to the support frame 200, and the manipulator 400 is fixedly connected to the first mounting rod 211. The two second mounting rods 212 are fixedly connected to the two ends of the first mounting rod 211, and the ends of the second mounting rods 212 facing away from the first mounting rod 211 are fixedly connected to the support frame 200, so that the manipulator 400 can be easily installed on the first mounting rod 211, making it easier to hang the manipulator 400 on the cross arm 210, and can also improve the structural strength of the cross arm 210, reduce the deformation of the cross arm 210, stabilize the position of the manipulator 400, and improve the position stability of the manipulator 400.

[0038] It should be noted that one end of the connecting rod 310 is fixedly connected to the support frame 200, and the other end is fixedly connected to the second mounting rod 212, so that the second mounting rod 212 can be stabilized on the support frame 200, and the first mounting rod 211 can be stabilized on the second mounting rod 212, thereby making the manipulator 400 stable on the first mounting rod 211.

[0039] In addition, the first mounting rod 211 and the second mounting rod 212 are connected together by welding.

[0040] Specifically, refer to Figure 3 and Figure 4 The distance between the two second mounting rods 212 gradually decreases as they approach the first mounting rod 211. By gradually decreasing the distance between the two second mounting rods 212 as they approach the first mounting rod 211, the connection strength between the first mounting rod 211 and the second mounting rod 212 can be improved, and deformation of the second mounting rod 212 can be reduced. This allows the connection between the first mounting rod 211 and the second mounting rod 212 to remain stable, reduces the possibility of separation between the first mounting rod 211 and the second mounting rod 212, and improves the reliability of the cross arm 210.

[0041] It should be noted that by setting the distance between the two second mounting rods 212 to gradually decrease in the direction closer to the first mounting rod 211, the force generated by the manipulator 400 during operation can be transmitted more to the length direction of the second mounting rod 212, thereby reducing the bending stress borne by the second mounting rod 212, improving the deformation resistance of the cross arm 210, and improving the position stability of the manipulator 400.

[0042] Specifically, refer to Figure 3 and Figure 4 The cross arm 210 further includes a cross brace 213, the ends of which are fixedly connected to the two second mounting rods 212. The cross brace 213 is disposed between the two second mounting rods 212 to improve the positional stability of the two second mounting rods 212, thereby stabilizing the two second mounting rods 212 on the support frame 200, reducing positional shaking and deformation of the second mounting rods 212, and thereby improving the structural rigidity of the cross arm 210 and the positional stability of the manipulator 400.

[0043] Among them, reference Figure 6 The number of the cross braces 213 is set to be multiple, and the multiple cross braces 213 are arranged at intervals to improve the position stability of the two second mounting rods 212, reduce the deformation of the second mounting rods 212, and improve the reliability of the cross arm 210.

[0044] Specifically, refer to Figure 5 and Figure 6The connecting rod 310, the first mounting rod 211, the second mounting rod 212, and the cross brace 213 are all configured as I-beams. By configuring the connecting rod 310, the first mounting rod 211, the second mounting rod 212, and the cross brace 213 as I-beams, the structural strength of the connecting rod 310, the first mounting rod 211, the second mounting rod 212, and the cross brace 213 is improved, and the possibility of deformation is reduced.

[0045] Specifically, by configuring the connecting rod 310 to be an I-beam, the connection stability between the support frame 200 and the cross arm 210 can be improved, allowing the cross arm 210 to be stably positioned on the support frame 200, reducing the possibility of cross arm 210 bending, and improving the support stability of the manipulator 400. By configuring the first mounting rod 211, the second mounting rod 212, and the cross brace rod 213 to be all I-beams, the structural strength of the cross arm 210 is increased, the possibility of cross arm 210 deformation is reduced, the support force for the manipulator 400 is increased, and the reliability of the symmetrical gantry is improved.

[0046] In addition, the side walls of the first mounting rod 211 , the second mounting rod 212 and the cross brace rod 213 are each provided with a plurality of side support plates to improve the structural strength of the first mounting rod 211 , the second mounting rod 212 and the cross brace rod 213 and reduce the possibility of deformation of the cross arm 210 .

[0047] It is understandable that, referring to Figure 5 and Figure 6 The reinforcing mechanism 300 further includes a support leg 340, the ends of which are fixedly connected to the frame 100 and the support frame 200, respectively. The support leg 340 is located on one side of the support plate 330. By arranging the support leg 340 on one side of the support plate 330, one end of the support leg 340 is fixedly connected to the frame 100 and the other end is fixedly connected to the support frame 200, thereby improving the support stability of the support frame 200, thereby improving the position stability of the support frame 200, reducing the deformation of the support frame 200, and improving the support stability of the manipulator 400.

[0048] It should be noted that the diagonal support rod 320 is arranged on the side of the support frame 200 away from the cross arm 210, and the support leg 340 is arranged on the support frame 200 and is located on one side of the support plate 330. Through the cooperation of the diagonal support rod 320 and the support leg 340, the support frame 200 can be supported in two directions, so that the support frame 200 can be stabilized on the frame 100, thereby improving the position stability of the support frame 200 and enabling the manipulator 400 to remain stable.

[0049] Specifically, refer to Figure 5 and Figure 6The end of the support leg 340 near the support frame 200 is provided with a connecting plate 341, and the support frame 200 and the diagonal brace 320 are fixedly connected to the connecting plate 341. The connecting plate 341 is provided at the end of the support leg 340 near the support frame 200. By providing the connecting plate 341, the contact area between the support leg 340 and the support frame 200 can be increased, thereby stabilizing the support leg 340 on the support frame 200, improving the deformation resistance of the support leg 340, and further improving the stability of the support frame 200.

[0050] In addition, the support frame 200 and the diagonal support rod 320 are fixedly connected to the connecting plate 341 to improve the connection strength between the support frame 200 and the diagonal support rod 320, so that the diagonal support rod 320 can be stably placed on the support frame 200, making it easier for the diagonal support rod 320 to absorb the load of the support frame 200, reducing the possibility of deformation of the support frame 200, and improving the reliability of the symmetrical gantry.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
