Technical Field

[0001] The utility model relates to the technical field of mechanical engineering protection, in particular to a mobile safety protection device for mechanical engineering. Background Technique

[0002] Mechanical engineering is an engineering discipline that involves using physical laws to analyze, design, manufacture, and repair mechanical systems. Mechanical engineering is based on relevant natural sciences and technical sciences as theoretical foundations, combined with technical experience in production practice, to study and solve all theoretical and practical problems in the development, design, manufacture, installation, operation, and maintenance of various machinery. In the production process of mechanical engineering, safety protection fences need to be set up to prevent other people from straying in and causing safety accidents.

[0003] At present, the existing mobile safety protection devices for mechanical engineering have a fixed height and cannot adjust the height of the protection device, which will cause people to step over the warning poles, resulting in the inability to play an effective protection role, thus greatly reducing the practicality of the safety protection device. For this reason, we propose a mobile safety protection device for mechanical engineering to solve the above problems. Content of the Utility Model

[0022] Please refer to Figures 1-4, in the present utility model, a mobile safety protection device for mechanical engineering includes a bottom plate 1. On the upper surface of the bottom plate 1, two hollow columns 2 are fixedly connected. Through grooves 3 are opened on one side surface of the two hollow columns 2 close to each other. On one side surface of the two hollow columns 2 close to each other, two fixed protection plates 4 are fixedly connected together. Two sealing bearings 5 are fixedly embedded in the inner wall of one of the hollow columns 2. The inner rings of the two sealing bearings 5 are fixedly connected with a threaded rod 6. The top end of the threaded rod 6 is fixedly connected with a connection disk 7. On the upper surface of the connection disk 7, a hand crank 8 is fixedly connected. The outer ring of the threaded rod 6 is threadedly connected with a threaded block 9. On the right side surface of the threaded block 9, a connecting plate 10 is fixedly connected. On the upper surface of the connecting plate 10, a lifting protection plate 11 is fixedly connected. By using the connection disk 7 and the hand crank 8, the threaded rod 6 can be driven to rotate. In this way, the threaded block 9 can be made to slide up and down by the rotation of the threaded rod 6. Furthermore, the threaded block 9 can drive the connecting plate 10 and the lifting protection plate 11 to move up and down. In this way, the staff can adjust the height of the lifting protection plate 11 according to actual needs.

[0023] On the bottom surface of the bottom plate 1, two groups of universal wheels 12 are fixedly connected. On one side surface of the two hollow columns 2 far from each other, two pushing handles 13 are fixedly connected. On the front surface of one of the hollow columns 2, a control button 14 is fixedly connected. On the upper surface of one of the hollow columns 2, a lighting lamp 15 is fixedly installed. On one side surface of the two fixed protection plates 4 far from each other, a group of first reflective strips 16 are fixedly connected. On one side surface of the two fixed protection plates 4 far from each other, first warning signs 17 are fixedly connected. On the front surface and the back surface of the lifting protection plate 11, a group of second reflective strips 18 are fixedly connected. On the front surface and the back surface of the lifting protection plate 11, second warning signs 19 are fixedly connected. By using the universal wheels 12 and the pushing handles 13, it is convenient for the staff to move this device. By using the lighting lamp 15, a good lighting effect and warning effect can be achieved at night. By using the first reflective strips 16 and the second reflective strips 18, a good reflective effect can be achieved on pedestrians or vehicles in the distance at night.

[0024] On the inner side wall of one of the hollow columns 2, a sliding groove 20 is opened. Inside the sliding groove 20, a sliding block 21 is slidably connected. The right side surface of the sliding block 21 is connected to the left side surface of the threaded block 9. Inside one of the hollow columns 2, a limiting rod 22 is fixedly connected. The outer ring of the limiting rod 22 is slidably connected with a limiting block 23. The left side surface of the limiting block 23 is connected to the right side surface of the connecting plate 10. By the cooperation of the sliding groove 20 and the sliding block 21, the threaded block 9 can be limited. In this way, the threaded block 9 can slide up and down more smoothly. By the cooperation of the limiting rod 22 and the limiting block 23, when the threaded block 9 drives the connecting plate 10 and the lifting protection plate 11 to move up and down, it can be more stable.

[0025] The working principle of the present utility model is:

[0026] When this device is in use, the staff first use the push handle 13 and the universal wheels 12 to push this device to the designated position and connect this device to an external power source. Immediately afterwards, the staff adjust the height of the lifting protection plate 11 according to actual needs. When adjusting the height of the lifting protection plate 11, the staff first use the hand rocker 8 and the connecting plate 7 to rotate the threaded rod 6, thereby causing the threaded block 9 to slide up and down on the outer circle of the threaded rod 6. When the threaded block 9 slides up and down, it will drive the connecting plate 10 and the lifting protection plate 11 to rise and fall. When the lifting protection plate 11 rises to the designated height, this device can start normal use. The above is the entire operation process of this device.

[0027] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
