[0022] 2. By arranging the buffer energy dissipation components around the bottom of the curved plate, when the slag blocks fall onto the curved plate, the entire curved plate can evenly bear and disperse the impact force in all directions, thereby more stably and effectively buffering and dissipating the slag blocks, and improving the overall protection performance. The guide columns slide with the sliding grooves of the receiving platform and the sliding grooves on the top of the partition, respectively, to provide precise guidance for the up and down movement of the curved plate when it is subjected to impact force. When the slag blocks fall and press the curved plate downward, the guide columns slide along the sliding grooves and the sliding grooves to ensure that the curved plate moves in the predetermined direction. Smooth movement ensures the stability of the entire structure during the buffering and energy dissipation process. The elastic part is located between the arc plate and the receiving platform or between the arc plate and the top of the partition. It can not only absorb and buffer the impact force through elastic deformation when the slag block hits the arc plate, but also after the impact force disappears, it can reset the arc plate upward by relying on its own elastic recovery force, so that the entire buffering and energy dissipation component can be restored to its initial state, so that it can continue to perform buffering and energy dissipation operations on subsequent falling slag blocks, ensuring that the buffering and energy dissipation component can be recycled, and improving the reliability and service life of the structure.

The arc plate 36 is provided above the water collection space 37 through the buffer energy dissipation component 316, and the arc plate 36 has a plurality of water leakage holes 39;

[0039] The buffering and energy dissipation component 316 buffers and dissipates the energy of the slag blocks that fall onto the arc-shaped plate 36;

[0040] The moving mechanism 1 is used to simultaneously drive the supporting mechanism 2 and the protecting mechanism 3 to move forward and backward or left and right.

[0041] The telescopic seat 22 is pushed upward by the linear power member 25, so that the cross arm 23, the suspension arm 24 and the protection mechanism 3 are higher than the guardrail 5 of the bridge body 4. The moving mechanism 1 moves horizontally toward the side close to the guardrail 5, so that the protection mechanism 3 is suspended below the side edge of the bridge. The moving mechanism 1 moves horizontally toward the side away from the guardrail 5, so that the tops of the two side plates 33 and the side plates 34 are in contact with the bottom of the bridge body 4. When the bridge guardrail 5 is cut, the slag or concrete wastewater falls onto the curved plate 36, and the concrete wastewater falls into the water collection space 37 through the leakage holes 39 on the curved plate 36. The slag blocks slide along the curved plate 36 to the slag block collecting space 38, so that the wastewater and the slag blocks can be treated separately, which improves the convenience and efficiency of the treatment and helps to keep the entire device and its surrounding environment clean.

[0042] In this embodiment, please refer to Figure 4The buffering and energy dissipating components 316 have four groups, and the four groups of buffering and energy dissipating components 316 are located around the bottom of the arc plate 36. Each group of the buffering and energy dissipating components 316 includes a guide column 3161 that is perpendicular to and fixed to the bottom of the arc plate 36, and an elastic member 3162 for resetting the arc plate 36 upward; the side of the first protective plate 31 facing the bridge body 4 has two receiving platforms 3163, and the receiving platforms 3163 have sliding grooves 3164 that slide with the guide columns 3161, and the elastic member 3162 is located between the arc plate 36 and the receiving platforms 3163; the top of the partition 35 has two sliding grooves 3165 that slide with the two guide columns 3161 respectively, and the elastic member 3162 is located between the arc plate 36 and the top of the partition 35.

[0043] The buffering and energy dissipation components 316 are arranged around the bottom of the arc plate 36, so that when the slag blocks fall onto the arc plate 36, the entire arc plate 36 can evenly withstand and disperse the impact force in all directions, thereby more stably and effectively buffering and dissipating the slag blocks, thereby improving the overall protection performance. The guide column 3161 slides with the sliding groove 3164 of the receiving platform 3163 and the sliding groove 3165 on the top of the partition 35, respectively, to provide precise guidance for the up and down movement of the arc plate 36 when it is subjected to impact force. When the slag blocks fall and press the arc plate 36 downward, the guide column 3161 slides along the sliding groove 3164 and the sliding groove 3165, which can ensure that the arc plate 36 The plate 36 moves smoothly in a predetermined direction, ensuring the stability of the entire structure during the buffering and energy dissipation process. The elastic member 3162 is located between the arc plate 36 and the receiving platform 3163 or between the arc plate 36 and the top of the partition 35. It can not only absorb and buffer the impact force through elastic deformation when the slag block hits the arc plate 36, but also after the impact force disappears, it can reset the arc plate 36 upward by virtue of its own elastic recovery force, so that the entire buffering and energy dissipation assembly 316 is restored to its initial state, so that it can continue to perform buffering and energy dissipation operations on subsequent falling slag blocks, ensuring that the buffering and energy dissipation assembly 316 can be recycled, thereby improving the reliability and service life of the structure.

[0044] In this embodiment, please refer to Figure 4 The elastic member 3162 includes a spring, which is sleeved on the guide post 3161.

The addition of the second protective plates 310, together with the first protective plates 31, forms a more complete protective barrier, effectively preventing splashing slag from falling from the sides and causing damage to the road or personnel, while also improving the overall structural strength.

[0046] In this embodiment, please refer to Figure 3 At least one reinforcing rib 311 is provided between each second protective plate 310 and the first protective plate 31. The reinforcing ribs 311 provide a tighter and more stable connection between the second protective plates 310 and the first protective plates 31, helping to reduce deformation and vibration of the protective mechanism 3 when subjected to stress, thereby improving the stability of the entire protective mechanism 3.

[0047] In this embodiment, please refer to Figure 4 The protective mechanism 3 also includes a liquid level sensor provided on the partition 35 and a water pump 313 installed in the water collection space 37.

The liquid level sensor is a float-type liquid level sensor or a radar liquid level sensor. The water collection bucket 315 can be placed on the mobile mechanism 1 or on the bridge deck of the bridge body 4 when in use. Through the cooperation of the liquid level sensor and the water pump 313, the accumulated water in the water collection space 37 can be pumped out and stored in the water collection bucket 315, preventing the weight load of the protective mechanism 3 from increasing due to excessive accumulated water, thereby ensuring the normal use and structural stability of the protective mechanism 3.

[0048] In this embodiment, please refer to Figure 2 The linear power member 25 includes a hydraulic cylinder, a pneumatic cylinder or an electric push rod. The fixed end of the linear power member 25 is fixedly connected to the top of the moving mechanism 1, and the telescopic end of the linear power member 25 is fixedly connected to the telescopic seat 22, so that power can be directly and effectively transmitted to the telescopic seat 22, driving the telescopic seat 22 to move up and down.

[0049] In this embodiment, please refer to Figure 5The mobile mechanism 1 includes a frame 11, four wheat wheels 12, and a power module 13. Two of the wheat wheels 12 are located on a diagonal line of the frame 11, and their rotation direction is consistent with the front-to-back direction of the frame 11. The other two wheat wheels 12 are located on another diagonal line of the frame 11, and their rotation direction is consistent with the left-right direction of the frame 11. There are four power modules 13, and the four power modules 13 respectively drive the four wheat wheels 12 to rotate. By adopting a diagonal layout of the four wheat wheels 12 and combining different rotation directions, the frame 11 can achieve all-round movement such as front-to-back, left-to-right, and diagonal. By accurately controlling the rotation direction and speed of the four wheat wheels 12 through the power module 13, it is possible to achieve precise control of the movement of the frame 11, so as to improve the accuracy and efficiency of the operation.

[0050] In this embodiment, please refer to Figure 5 The power module 13 includes a motor, which can provide sufficient torque at startup to enable the wheat wheel 12 to overcome resistance such as static friction and start quickly and enter a stable operating state. The motor can also be wirelessly controlled, so that the operator can operate the motor at a location far away from the mobile mechanism 1, thereby improving safety.

[0051] Working principle: When in use, the mobile mechanism 1 moves forward to the working area, and the linear power member 25 pushes the telescopic seat 22 to move upward, so that the cross arm 23, the suspension arm 24 and the protective mechanism 3 are higher than the guardrail 5 of the bridge body 4.

When the slag blocks fall and press the curved plate 36 downward, the guide posts 3161 slide along the sliding groove 3164 and the sliding groove 3165 165 sliding, can ensure that the arc plate 36 moves smoothly in a predetermined direction, ensuring the stability of the entire structure during the buffering and energy dissipation process. The elastic member 3162 is located between the arc plate 36 and the receiving platform 3163 or between the arc plate 36 and the top of the partition 35. It can not only absorb and buffer the impact force through elastic deformation when the slag block hits the arc plate 36, but also after the impact force disappears, it can reset the arc plate 36 upward by relying on its own elastic restoring force, so that the entire buffering and energy dissipation assembly 316 returns to its initial state, so that it can continue to buffer and dissipate the energy of the subsequent falling slag blocks, ensuring The buffering and energy dissipation component 316 can be recycled, which improves the reliability and service life of the structure. The second protective plate 310 and the first protective plate 31 together form a more complete protective barrier, which can effectively prevent splashing slag blocks from falling and causing road or personal damage, and can also improve the overall structural strength. When there is too much wastewater in the water collection space 37, the accumulated water in the water collection space 37 can be pumped out and stored in the water collection bucket 315 through the cooperation of the liquid level sensor and the water pump 313, so as to prevent the weight load of the protective mechanism 3 from increasing due to excessive water accumulation, thereby ensuring the normal use of the protective mechanism 3 and the stability of the structure.

[0052] In summary, the utility model pushes the telescopic seat 22 upward through the linear power member 25, so that the cross arm 23, the suspension arm 24 and the protection mechanism 3 are higher than the guardrail 5 of the bridge body 4, and the mobile mechanism 1 moves horizontally to the side close to the guardrail 5, so that the protection mechanism 3 is suspended below the side edge of the bridge, and the mobile mechanism 1 moves horizontally to the side away from the guardrail 5, so that the tops of the two side plates 33 and the side plates 34 are in contact with the bottom of the bridge body 4. When the bridge guardrail 5 is cut, the slag or concrete wastewater falls onto the curved plate 36, and the concrete wastewater falls into the water collection space 37 through the leakage hole 39 on the curved plate 36.
