[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a hydraulic mechanical protection device, comprising a bottom plate 1, a hydraulic cylinder 4 is installed at the middle of the top of the bottom plate 1, pillars 5 are fixedly connected to the middle of the top of the bottom plate 1, a fixed plate 13 is fixedly connected to the top of the pillar 5, a force-bearing shell 7 is slidably connected to the top of the fixed plate 13, springs 8 are fixedly connected to the outer wall of the force-bearing shell 7, an external shell 9 is fixedly connected to the top of the spring 8, and a protection mechanism 2 is installed on the top of the bottom plate 1; bolts 3 are threadedly connected at the four corners of the top of the bottom plate 1; a slider 6 is fixedly connected to the bottom of the force-bearing shell 7, a slide groove 10 is opened on the top wall of the fixed plate 13, and the slider 6 is slidably connected to the corresponding slide groove 10 respectively;

[0028] Specifically, the hydraulic cylinder 4, as the core component of the device, is responsible for performing the task of lifting objects; however, in the production process, it is inevitable that objects will accidentally fall; at this time, the semicircular design of the external shell 9 and the force-bearing shell 7 plays a key role; this design can provide all-round protection for the hydraulic cylinder 4 and effectively reduce the direct impact of external factors on the hydraulic cylinder 4; when the object falls on the external shell 9, the spring 8 will react quickly and drive the external shell 9 to shrink and release force; this process not only alleviates the impact force of the object on the external shell 9, but also protects the hydraulic cylinder 4 from damage; at the same time, the weight of the squeezed force of the force-bearing shell 7 will drive the slider 6 to slide in the slide groove 10; this sliding mechanism enables the object to slide quickly from the external shell 9, further reducing the risk of damage to the hydraulic cylinder 4 caused by damage to the external shell 9.

[0029] Reference Figure 1 and Figure 3 The protection mechanism 2 includes a double-headed motor 201, the bottom of the double-headed motor 201 is fixedly connected to the top front side of the bottom plate 1, the output ends of the double-headed motor 201 are fixedly connected with threaded rods 202, the outer side of the threaded rods 202 is threadedly connected with baffles 203, the front and rear ends of the left baffle 203 are fixedly connected with plug-in plates 205, the front and rear ends of the right baffle 203 are fixedly connected with hollow blocks 204, and the plug-in plates 205 are respectively engaged with the corresponding hollow blocks 204; the bottom of the baffle 203 is fixedly connected with a sliding block 11, and the left and right sides of the top wall of the bottom plate 1 are provided with sliding rails 12, and the sliding blocks 11 are respectively slidably connected with the corresponding sliding rails 12;

[0030] Specifically, the double-headed motor 201 is the power source of the entire system. Its startup will trigger a series of precise linkage reactions. When the motor starts working, it will drive the threaded rod 202 to rotate. This rotation is not isolated, but closely linked to the movement of the baffle 203. In this system, the baffle 203 is cleverly designed into multiple structures to meet the needs of use in different scenarios. The bottom baffle 203 is made of solid stainless steel to ensure that it has sufficient strength and stability when bearing the pressure of heavy objects. The other baffles 203 are made of rubber material to absorb impact and reduce noise; as the threaded rod 202 rotates, the baffle 203 begins to move; this movement is not random, but carefully planned to ensure that the items move stably in a specific area; at the same time, the sliding block 11 slides in the slide rail 12, further ensuring the smoothness and accuracy of the movement of the baffle 203; in this process, the plug plate 205 is slowly pulled out of the hollow block 204 to form a protective circle to isolate the environment around the hydraulic cylinder 4; the size of this protective circle can be adjusted according to the moving distance of the baffle 203, so as to adapt to hydraulic cylinders 4 of different sizes and different working environments; this design not only prevents the items from rolling around during transportation, but also improves overall work efficiency and safety.

[0031] Reference Figure 3 , the two hollow blocks 204 are symmetrically designed; the baffle 203 is a rubber baffle 203;

[0032] Specifically, the symmetrically designed hollow block 204 can increase the accuracy of protection, and after an object falls, it can be limited and blocked by the baffle plate 203 made of rubber material.

[0033] Working principle: The bottom plate 1 is installed in the factory or the position where the hydraulic cylinder 4 is needed by bolts 3, and the hydraulic cylinder 4 is turned on to lift the objects. When the objects fall accidentally, the objects fall on the external shell 9. The external shell 9 and the force-bearing shell 7 are semicircular in design, which can protect the hydraulic cylinder 4 in all directions. When the external shell 9 contacts the objects, the spring 8 drives the external shell 9 to shrink and release the force. At the same time, the weight of the force-bearing shell 7 is squeezed and drives the slider 6 to slide in the slide 10, so that the objects can slide off the external shell 9 quickly, reducing the damage to the hydraulic cylinder 4 caused by the damage to the external shell 9, which can meet the use requirements, and turn on the double-headed motor 201 The threaded rod 202 is driven to rotate, and the rotation of the threaded rod 202 drives the baffle 203 to move. The baffle 203 is arranged in multiple pieces. The lowest baffle 203 is made of stainless steel, and the rest are made of rubber. When the baffle 203 moves, it drives the sliding block 11 to slide in the slide rail 12, and the moving trajectory of the baffle 203 is planned. At the same time, the plug plate 205 is slowly pulled out from the hollow block 204, and a protection circle can be formed around the hydraulic cylinder 4. The size of the protection circle can be determined according to the moving distance of the baffle 203. After the object falls, it can be limited and blocked according to the rubber baffle 203, thereby preventing the object from rolling around, which brings convenience to use.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
