[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 , an embodiment provided by the present utility model: a safety protection warning device for a tensioning area, including a chain machine 1, a tensioning machine 2 is arranged on the right side of the chain machine 1, a protective retaining wall 3 is arranged outside the tensioning machine 2 and the chain machine 1, the protective retaining wall 3 can protect the left side of the chain machine 1 and the right side of the tensioning machine 2, and the inside of the protective retaining wall 3 constitutes the working area of the tensioning machine 2, which is the tensioning area.

[0032] Referring to Figures 2 - 4, mounting grooves 4 are formed on both the left and right sides of the upper surface of the protective retaining wall 3. An elastic member 5 is fixedly connected to the inner bottom surface of the mounting groove 4. The upper end of the elastic member 5 is fixedly installed with a base 6. When the base 6 moves downward, the elastic member 5 can be extruded, causing the elastic member 5 to compress and generate elastic potential energy. The base 6 is inserted into the mounting groove 4, and the base 6 can perform linear motion in the vertical direction inside the mounting groove 4. A guiding unit is arranged on the outer side of the base 6. The guiding unit includes a guiding groove 61. The guiding groove 61 is formed on the inner wall surface of the mounting groove 4. A guiding block 62 is slidably connected to the inside of the guiding groove 61. The guiding block 62 can perform linear motion in the vertical direction inside the guiding groove 61. The outer wall surface of the guiding block 62 is fixedly connected to the side wall of the base 6.

[0033] Through the cooperation of the arranged guiding groove 61 and guiding block 62, the movement of the base 6 can be guided and limited, preventing the base 6 from shifting and getting stuck when moving inside the mounting groove 4. An alarm 7 is detachably connected above the base 6. The alarm 7 is turned on by connecting to the switch of the tensioning machine 2. When the tensioning machine 2 works or stops, the alarm 7 can be automatically turned on or off simultaneously. And when it is turned off, the alarm 7 is stopped after a two-minute delay by a time relay to ensure that the mold is transported out of the tensioning area. The work of the alarm 7 can be used to remind the personnel passing through this area to avoid or stay away from this working area, preventing the occurrence of industrial injury accidents.

[0034] A protective cover 8 is arranged on the outer side of the alarm 7. The bottom surface of the protective cover 8 is at the same horizontal plane as the upper surface of the base 6. The protective cover 8 can protect the outer side of the alarm 7, preventing the outside from directly contacting and hitting the alarm 7 and causing its damage. At the same time, through holes are formed on the outer side of the protective cover 8, enabling the alarm sound emitted by the alarm 7 to spread out. A fixing unit is arranged at the bottom of the protective cover 8. The fixing unit includes a threaded cylinder 81. The threaded cylinder 81 is fixedly connected to the bottom end of the protective cover 8. When the protective cover 8 rotates and moves, the threaded cylinder 81 can move synchronously. An annular threaded groove 82 is formed on the upper surface of the base 6. The threaded cylinder 81 is threadedly connected to the inside of the annular threaded groove 82. When the protective cover 8 rotates and drives the threaded cylinder 81 to rotate synchronously, the protective cover 8 can be driven to perform linear motion in the vertical direction relative to the base 6 under the cooperation of the annular threaded groove 82. Thus, when the protective cover 8 is deformed due to external impact and affects the protection effect on the alarm 7, the protective cover 8 can be detached and replaced separately, with simple operation.

[0035] Refer to Figures 3 - 4, a circular hole 9 is provided on the upper surface of the base 6, a circular block 10 is inserted into the interior of the circular hole 9, the upper surface of the circular block 10 is fixedly connected to the bottom surface of the alarm 7, and the circular block 10 can be directly taken out from the circular hole 9 when it moves upward. At the same time, when the circular block 10 is inserted into the interior of the circular hole 9, the horizontal movement of the circular block 10 and the alarm 7 can be limited to prevent the alarm 7 from shifting horizontally during use. A keel frame 11 is fixedly connected to the inner wall surface of the protective cover 8. By providing the keel frame 11, the interior of the protective cover 8 can be supported, further enhancing the overall strength of the protective cover 8. A rubber block 12 is fixedly connected to the inner top surface of the keel frame 11, and the bottom surface of the rubber block 12 is in mutual fit with the upper end of the alarm 7. After the protective cover 8 is installed above the base 6, the keel frame 11 and the alarm 7 can squeeze the rubber block 12, so that the rubber block 12 can further limit the alarm 7 to prevent the alarm 7 from bouncing up and down during operation and colliding with the base 6 or the keel frame 11 and being damaged.

[0036] Working principle: The alarm 7 is turned on by connecting the switch of the tensioning machine 2. When the tensioning machine 2 works or stops, the alarm 7 can be automatically turned on or off at the same time, and it can remind the personnel passing through this area to avoid or stay away from this working area through the operation of this device, preventing work injury accidents. During the use of the tensioning machine 2, when situations such as broken tendons, slipping tendons, and fracture of the tensioning parts causing the overall flying out of the steel bar framework occur, if an object flies out to the outside of the alarm 7, the provided protective cover 8 can protect the alarm 7. At the same time, after the protective cover 8 is stressed, it will squeeze the base 6 downward, causing the base 6 to squeeze the elastic member 5 to move downward, driving the protective cover 8 into the installation groove 4, and buffering and avoiding the impact force through the elastic potential energy of the elastic member 5, reducing the situation where the protective cover 8 is directly damaged after being impacted, and further enhancing the protection effect on the alarm 7. When the protective cover 8 is damaged or the alarm 7 needs to be repaired, the protective cover 8 can be directly screwed, so that the protective cover 8 moves downward through the cooperation of the threaded cylinder 81 and the annular thread groove 82, disconnects from the connection with the base 6, thereby driving the keel frame 11 and the rubber block 12 to move upward, releasing the limit on the alarm 7, and enabling the alarm 7 to be directly moved upward to complete the disassembly, with simple operation.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
