The following describes an embodiment of the present invention based on its overall structure.

[0025] Example

[0026] like Figures 1 to 3 As shown, a hot billet anti-fall protection device specifically includes hot billet seats 200 installed on opposite sides of the loading and unloading vehicle platform 100. It is worth mentioning that the hot billet seats 200 are trapezoidal in structure and made of steel. The top of the hot billet seat 200 is arranged obliquely downward, and the inclination direction is toward one side of the loading and unloading vehicle platform 100. The two hot billet seats 200 form a V-shaped feeding port above to facilitate receiving the hot billet 400. The hot billet seat 200 is installed on the loading and unloading vehicle platform 100 by bolting or welding to ensure the stability of the installation of the hot billet seat 200.

[0027] Preferably, a housing cavity 210 is formed inside the hot blank seat 200, and an anti-drop protection device 300 is housed in the housing cavity 210. The anti-drop protection device 300 is made of steel; the anti-drop protection device 300 includes a driving source 310, a driving connecting rod 320, a protective baffle 330, a sliding baffle 340 and a limiting vertical rod 350. The driving source 310 is installed below the loading and unloading vehicle platform 100. It is worth mentioning that the driving source 310 directly uses the air-driven telescopic cylinder on the loading and unloading vehicle. One end of the driving link 320 is connected to the output end of the driving source 310, and the other end is rotatably mounted with a protective baffle 330. The sliding baffle 340 is mounted on the driving link 320, and the limiting vertical rod 350 is inserted into the hot billet seat 200 perpendicular to the horizontal plane. The limiting vertical rod 350 and the inner wall of the hot billet seat 200 are used to limit the sliding baffle 340 from sliding out of the accommodating cavity 210, and at the same time, the sliding baffle 340 is also abutted against, so that the protective baffle 330 does not retreat during the pushing process. The driving source 310 drives the protective baffle 330 to push the hot steel billet 400 placed on the loading and unloading vehicle platform 100, ensuring that the hot steel billet 400 is stably loaded on the loading and unloading vehicle platform 100 during transportation without tipping or falling.

[0028] In some preferred embodiments, a protective baffle plate accommodating entrance 220 and a driving link member accommodating entrance 230 are opened on the side of the hot blank seat 200 facing the loading and unloading vehicle platform 100. The width of the protective baffle plate accommodating entrance 220 and the driving link member accommodating entrance 230 is smaller than the length of the sliding block rod 340 to ensure that the sliding block rod 340 cannot slide out of the accommodating cavity 210. Under the drive of the driving source 310, the driving link member 320 pushes the sliding block rod 340, and the sliding block rod 340 0 moves up and down (slides) along the height direction of the hot blank seat 200. At the same time, driven by the driving link member 320, the protective baffle 330 can be pushed out or retracted from the protective baffle accommodating inlet 220. In the process of pushing out or retracting the protective baffle 330 from the protective baffle accommodating inlet 220, the driving link member 320 also swings at the driving link member accommodating inlet 230. The protective baffle accommodating inlet 220 and the driving link member accommodating inlet 230 are both connected to the accommodating cavity 210.

[0029] In some preferred embodiments, a socket 240 is provided on the inclined surface above the hot blank seat 200, and a slot corresponding to the socket 240 is also provided inside the hot blank seat 200. The slot is coaxially arranged with the socket 240 to ensure that the limiting vertical rod 350 remains in a vertical state when inserted, and the limiting vertical rod 350 will not affect the connecting rod movement of the driving connecting rod 320, and the limiting vertical rod 350 is inserted from the socket 240.

[0030] In some preferred embodiments, the driving connecting rod 320 includes an output mounting rod 321, a driving connecting rod 322 and a mounting shaft 323. The output mounting rod 321 is mounted on the output end of the driving source 310 through a rod sleeve 324. The rod sleeve 324 is mounted on the output end of the driving source 310. Considering that the anti-fall protection device 300 is in contact with high-temperature objects for a long time, the rod sleeve 324 is not lubricated, but a rod bushing made of copper is used. The driving connecting rod 322 is rotatably connected to the output mounting rod 321, and the driving connecting rod 322 is rotatably connected to the protective baffle 330 through the mounting shaft 323. The mounting shaft 323 is mounted on the end of the driving connecting rod 322. The sliding baffle 340 is mounted on the rod body of the driving connecting rod 322, and the sliding baffle 340 is vertical to the driving connecting rod 322.

[0031] Comparison of the effects before and after using the anti-fall protection device and after adding the anti-fall protection device:

[0032] According to statistics before the transformation, there were two billet falling accidents per shift, and six billet falling accidents occurred during three shifts per day. The main plant's crane was occupied for about six hours to handle the accident, which affected the transportation efficiency of the fleet and seriously affected the production efficiency of the main plant.

[0033] 1. Transportation efficiency

[0034] Before the rectification, an average of two billet falling accidents occurred per shift, taking an average of two hours to resolve. Assuming an hourly impact on the transport capacity of two trucks (120 tons), this impacted 240 tons per shift, and a total of 720 tons per day across three shifts. Based on a per-ton billet charge of 4.25 yuan, the impact on output value was 3,060 yuan per day, or 91,800 yuan per month. If the impacted monthly output value is included in the output value after the technological development and transformation is implemented, the monthly output value will increase by over 90,000 yuan, for a cumulative annual increase of 1.08 million yuan.

[0035] 2. Repair costs

[0036] After installing the anti-drop protection device, the hot steel billet 400 (square billet) is always in a fixed state during transportation and will not shift due to the influence of vehicle speed and turning centrifugal force. It forms a protection for the square billet seat and reduces the maintenance frequency of the square billet seat. According to statistics, the maintenance frequency of the square billet seat of a vehicle before the transformation was 1.5 / month. The maintenance cost of the square billet seat is about 320 yuan depending on the degree of damage. The maintenance cost of the square billet seat of a vehicle is 6,000 yuan / year. 40 vehicles can save 240,000 yuan in maintenance costs a year.

[0037] 3. Main factory improves efficiency

[0038] Based on the calculation that one crane affects the main factory's operating time for 6 hours every day, after consulting the person in charge of crane management in the rod and wire factory, the monthly output value of a single crane is converted into 300,000 yuan based on the benefits. After the technical development and transformation, the crane output value is increased by 75,000 yuan per month, and the cumulative output value is increased by 900,000 yuan a year.

[0039] 4. Overall economic benefits

[0040] After the technical development and transformation is completed, the output value can be increased by 1.98 million yuan in one year; the maintenance cost can be reduced by 240,000 yuan; the technical transformation cost of 40 vehicles will total 200,000 yuan; and the overall direct and indirect economic benefits will be about 2.02 million yuan.

[0041] To sum up, the utility model provides a hot steel billet anti-fall protection device, which can dynamically change the reserved space between the hot steel billet and the hot billet seat, so as to prevent the hot steel billet from falling due to its own inertia during transportation and affecting the subsequent loading and unloading efficiency.
