However, it should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the scope of the utility model.

[0024] It should be noted that when an element is referred to as being "disposed on, provided with" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Please refer to the instruction manual Figure 1-4 The utility model provides a technical solution: a high-precision lifting platform, including a platform 10, a driving system is arranged at the bottom of the platform 10, and the driving system is divided into a main driving mechanism and a slave driving mechanism; the main driving mechanism includes a rigid chain 9, and the slave driving mechanism includes a hydraulic cylinder 7. The rigid chain 9 can accurately control the lifting accuracy of the product, but the rigid chain 9 has poor anti-side thrust capability. Therefore, the hydraulic cylinder 7 is used to support the stability of the lifting equipment and improve the anti-side thrust capability of the overall equipment.

[0027] The utility model is suitable for high-precision docking lifting work, especially for loading and unloading of missiles, and solves the problem that insufficient precision may lead to loading failure or safety accidents.

[0028] Among them, a rigid chain lifting platform 6 is fixedly arranged on the top of the rigid chain 9, and the top of the rigid chain lifting platform 6 is connected to the bottom of the platform 10. Two rigid chains 9 are arranged, and the two rigid chains 9 are respectively arranged at the diagonal positions of the platform 10; the hydraulic cylinder 7 is arranged at the other two diagonal positions at the bottom of the platform 10, and the telescopic end of the hydraulic cylinder 7 is fixedly connected to the bottom of the platform 10; the lifting and lowering of the platform 10 is completed by four supporting points, and the stability is high;

[0029] In actual use, the main drive mechanism and the slave drive mechanism are integrated and installed on the equipment base, which is highly integrated and suitable for lifting work in multiple fields. It only needs to install a suitable platform 10 without other modifications.

[0030] A synchronous shaft 2 is used between the two rigid chains 9 to achieve synchronous lifting. Specifically, the synchronous shaft 2 is arranged on the rigid chain drive motor 1, and the rigid chain drive motor 1 is arranged in the middle of the bottom surface of the platform 10. Both ends of the synchronous shaft 2 are connected with the second reduction motor 4. The first reduction motor 3 is also arranged on the synchronous shaft 2. The rigid chain 9 is arranged in the rigid chain storage box 5, and the output end of the second reduction motor 4 is connected to the rigid chain 9 by transmission. When working, the rigid chain drive motor 1 drives the synchronous shaft 2 through the first reduction motor 3 to achieve stable speed adjustment. The two ends of the synchronous shaft 2 are respectively connected to the two rigid chains 9 through the two second reduction motors 4 to complete the lifting operation, and the stability is high.

[0031] It should be noted that the connection between the second reduction motor 4 and the rigid chain 9 is an existing common connection mechanism, which will not be described here in detail and is not the focus of the present utility model.

[0032] A pressure sensor is installed between the bottom of the hydraulic cylinder 7 and the base of the equipment; a hydraulic pump station drive motor 8 is also provided at the bottom of the platform 10, and the hydraulic cylinder 7 is driven by the hydraulic cylinder motor pump, and the pressure sensor and the hydraulic pump station drive motor 8 are connected through a controller; when the pressure sensor detects that the pressure of the hydraulic cylinder 7 is too low, it feeds back to the controller to drive the hydraulic pump station drive motor 8 to accelerate, thereby increasing the lifting speed of the hydraulic cylinder 7; when the pressure is too high, the speed of the hydraulic cylinder 7 is reduced, thereby achieving relative synchronization between the hydraulic cylinder 7 and the rigid chain 9, ensuring that the lifting stability of the platform 10 is further improved, and making up for the shortcomings of the hydraulic cylinder 7 and the rigid chain 9.

[0033] It should be noted that the controller is not shown in the figure. It is a common existing technology and will not be described in detail here.

[0034] In actual use, the rigid chain drive motor 1 is provided with a self-locking component; the self-locking component is a common mechanism in the prior art for achieving the locking of the rigid chain drive motor 1, which can achieve the parking of the rigid chain lifting platform 6 and has high safety.

[0035] The hydraulic cylinder 7 is provided with an emergency self-locking mechanism, which is also a common mechanism in the prior art for locking the hydraulic cylinder 7 and can prevent the platform 10 from falling rapidly due to failure of the self-clamping component.

[0036] It is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
