[0026] Please also refer to Figures 1 to 6 The present invention provides a bridge construction sound insulation board transport trolley, which includes a vehicle body 1, a clamping assembly 2, and a pressing assembly 3. The vehicle body 1 has a plurality of accommodating cavities 11 for accommodating sound insulation boards 10, and the plurality of accommodating cavities 11 are arranged at intervals along the front-to-back direction. The clamping assembly 2 is arranged in a one-to-one correspondence with the accommodating cavities 11. The clamping assembly 2 includes two clamping plates 21 slidably connected to both sides of the vehicle body 1, and the clamping plates 21 can be brought close to each other to clamp on the end walls of the sound insulation boards 10. The pressing assembly 3 is arranged in a one-to-one correspondence within the accommodating cavities 11. The pressing assembly 3 includes a pressing plate 31 and a first elastic member 32. The pressing plate 31 is slidably connected to the accommodating cavities 11 along the front-to-back direction. The first elastic member 32 is connected between the pressing plate 31 and the side wall of the accommodating cavities 11 and is used to elastically push the pressing plate 31 to press against the side wall of the sound insulation board 10.

[0027] Compared to the prior art, the present embodiment provides a sound insulation board transport trolley for bridge construction. Multiple sound insulation boards 10 are placed one-to-one within multiple accommodating cavities 11. Two clamping plates 21 are clamped at each end of each sound insulation board 10 to secure the boards 10 in their lengthwise direction. Simultaneously, a first elastic member 32 elastically pushes a pressure plate 31 toward the side closest to the sound insulation board 10, pressing the pressure plate 31 against the sidewall of the sound insulation board 10 to secure the boards 10 in their thicknesswise direction. This arrangement separates the multiple sound insulation boards 10 within the multiple accommodating cavities 11, preventing collision and friction between the boards 10. Furthermore, the clamping assembly 2 and the pressure assembly 3 are used to effectively secure the boards 10, improving the efficiency and safety of transporting the sound insulation boards 10 during bridge construction.

[0028] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 1 and Figure 2 , a plurality of receiving grooves 12 for the sound insulation board 10 to pass through are respectively penetrated on the two side walls of the vehicle body 1, and the receiving grooves 12 are communicated with the receiving cavity 11. The clamping assembly 2 also includes a linkage frame 22, a second elastic member 23 and a linkage block 24. The linkage frame 22 is slidably connected to the receiving groove 12 in the up and down directions, and the linkage frame 22 is arranged through the receiving groove 12. Both ends of the linkage frame 22 are provided with a guide surface that gradually tilts from bottom to top toward the side of the receiving groove 12. The second elastic member 23 is connected between the bottom wall of the linkage frame 22 and the bottom wall of the receiving groove 12. The linkage block 24 is connected to the outer wall of the clamping plate 21 and presses against the guide surface. The linkage frame 22 can press down the second elastic member 23 under the action of the gravity of the sound insulation board 10, and use the guide surface to press the linkage block 24 so that the clamping plate 21 clamps the sound insulation board 10.

[0029] In this embodiment, the length of the sound insulation board 10 is greater than the width of the vehicle body 1. That is, when the sound insulation board 10 is placed on the vehicle body 1, the end walls of the sound insulation board 10 are located on the outside of the accommodating cavity 11. Therefore, a accommodating groove 12 communicating with the accommodating cavity 11 is provided on the vehicle body 1. The accommodating groove 12 is arranged to pass through the vehicle body 1 horizontally. At the same time, in order to facilitate the insertion of the sound insulation board 10 into the accommodating groove 12 from top to bottom, the width of the accommodating groove 12 is made greater than the thickness of the sound insulation board 10. At the same time, the sound insulation board 10 is effectively fixed by the clamping assembly 2 and the pressing assembly 3 to prevent the sound insulation board 10 from shaking in the accommodating groove 12.

[0030] In the clamping assembly 2, the linkage frame 22 drives the linkage block 24 to move horizontally, thereby driving the clamping plates 21 on both sides to move synchronously toward the receiving slot 12 to simultaneously clamp the two ends of the sound insulation board 10. Specifically, when the sound insulation board 10 is inserted into the receiving slot 12, the linkage frame 22 is pressed downward by the deadweight of the sound insulation board 10, and the second elastic member 23 is compressed. During the downward movement of the linkage frame 22, the linkage block 24 fixed to the outer side of the clamping plate 21 is driven horizontally by the inclined guide surface, so that the linkage block 24 drives the clamping plates 21 to move horizontally, thereby clamping the sound insulation board 10. When the sound insulation board 10 is removed from the receiving slot 12, the linkage frame 22 loses pressure, the second elastic member 23 rebounds, and drives the linkage frame 22 upward. As the linkage frame 22 moves upward, the linkage block 24 loses its pressure, causing the clamping plates 21 to release their clamping force on the sound insulation board 10, and the sound insulation board 10 can be smoothly removed. The clamping assembly 2 can not only clamp the two ends of the sound insulation board 10 through the two clamping plates 21, but also center the sound insulation board 10, thereby helping to ensure the stability of the sound insulation board 10 during transportation.

[0031] Furthermore, multiple second elastic members 23 can be provided along the direction of the linkage frame 22 to provide stable support for the linkage frame 22, ensuring that the linkage frame 22 moves downward stably under the pressure of the sound insulation board 10, and can move upward stably after the pressure of the sound insulation board 10 is lost.

[0032] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 3 and Figure 6 The two ends of the linkage frame 22 are respectively connected with an upwardly extending lever 221, the lever 221 is located on the outside of the linkage block 24, the guide surface is set on the inner side wall of the lever 221, and the linkage block 24 is rotatably connected with a roller 241, and the roller 241 rolls with the guide surface.

[0033] In this embodiment, under the influence of the gravity of the sound insulation panel 10, the linkage frame 22 drives the lever 221 downward. Simultaneously, the linkage block 24 moves inward under the pressure of the guide surface, thereby driving the clamping plate 21 to clamp the sound insulation panel 10. By providing a roller 241 on the linkage block 24 and ensuring that the roller 241 rolls against the guide surface, the friction between the linkage block 24 and the lever 221 is reduced, thereby improving the performance of the clamping assembly 2.

[0034] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 2 A sliding rod 13 extending horizontally outward is connected to the vehicle body 1, and the clamping plate 21 is slidably connected to the sliding rod 13. A third elastic member 25 is sleeved on the outer periphery of the sliding rod 13. The third elastic member 25 is located between the side wall of the vehicle body 1 and the clamping plate 21 and is used to elastically push the clamping plate 21 outward.

[0035] In this embodiment, four slide bars 13 are provided. These slide bars 13 are positioned two by two on either side of the receiving slot 12, and are positioned near the four corners of the clamping plate 21, ensuring stable sliding of the clamping plate 21. When the linkage frame 22, via the linkage block 24, drives the clamping plate 21 toward the receiving slot 12, the third elastic member 25 is compressed and acts as a buffer, ensuring that the clamping plate 21 is firmly clamped against the ends of the sound insulation board 10. When the linkage frame 22 moves upward as the sound insulation board 10 is removed, the third elastic member 25 pushes the clamping plates 21 outward, quickly releasing the sound insulation board 10 and ensuring that the distance between the two clamping plates 21 is greater than the length of the sound insulation board 10, facilitating its reinsertion. Furthermore, the provision of the third elastic member 25 ensures that the linkage block 24 and the linkage frame 22 maintain a constant press-fit relationship, enhancing the stability of the clamping assembly 2.

[0036] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 4 and Figure 5A slide groove 111 extending in the front-to-back direction is provided on the bottom wall of the accommodating cavity 11 , and a slider 311 slidingly matched with the slide groove 111 is connected to the pressure plate 31 .

[0037] In this embodiment, the pressure plate 31 is pressed against the side wall of the sound insulation board 10 by the elastic pushing action of the first elastic member 32. When the sound insulation board 10 needs to be removed, the pressure plate 31 is moved away from the sound insulation board 10 to press the first elastic member 32 to release the sound insulation board 10. The sliding engagement of the slider 311 and the slide groove 111 provides a guide for the movement of the pressure plate 31, preventing uneven force on the pressure plate 31 and causing it to tilt when the first elastic member 32 is pressed.

[0038] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 5 A push rod 33 is slidably connected to the vehicle body 1 along the front-to-back direction. The push rod 33 passes through the slide groove 111 , and the slider 311 is connected to the push rod 33 .

[0039] The elastic force of the first elastic member 32 presses the pressure plate 31 against the sidewall of the sound insulation board 10, compressing the board 10 while also buffering vibrations. When placing the sound insulation board 10, the pressure plate 31 must be pushed and the first elastic member 32 compressed to create space for the board 10. When removing the sound insulation board 10, the pressure plate 31 must also be pushed to release it. In this embodiment, multiple pressure plates 31 are connected to a single push rod 33 via sliders 311. Pushing the push rod 33 allows for synchronous movement of the multiple pressure plates 31, simplifying operation and improving transport efficiency.

[0040] Specifically, the push rod 33 is located below the accommodating cavity 11 and slidably engages with the vehicle body 1. The push rod 33 extends in the front-to-back direction and sequentially passes through multiple slide slots 111. Each slider 311 is fixedly connected to the push rod 33, so that the sliding of the push rod 33 can drive the synchronous movement of the pressure plate 31. More specifically, two sliders 311 are connected to the bottom of each pressure plate 31, and the two sliders 311 are respectively arranged near the end walls of the pressure plate 31. Correspondingly, two slide slots 111 are provided on the bottom wall of each accommodating slot 12, and two push rods 33 are also provided accordingly. The two push rods 33 respectively push the pressure plate 31 from both ends of the pressure plate 31, ensuring stable movement of the pressure plate 31.

[0041] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 5 The outer end of the push rod 33 is penetrated by an insertion rod 34 extending in the up and down direction. The insertion rod 34 slides with the push rod 33, and a positioning hole 14 is provided on the bottom plate of the vehicle body 1 to be plugged with the insertion rod 34.

[0042] In this embodiment, the push rod 33 is pushed to cause the multiple pressure plates 31 to move synchronously to release the sound insulation panels 10 in the corresponding accommodating cavities 11 respectively. At this time, the insertion rod 34 can be inserted into the positioning hole 14 to fix the axial position of the push rod 33, thereby fixing the pressure plates 31 in the open state, so as to smoothly complete the removal and placement operation of the sound insulation panels 10.

[0043] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 5 The upper end of the insertion rod 34 is connected to a horizontally extending handle 341, and the lower end of the insertion rod 34 is provided with a rounded corner.

[0044] In this embodiment, the length of the grip 341 matches the size of the operator's hand, making it easy for the operator to grasp. The operator can use the grip 341 to push the push rod 33. When the insertion rod 34 is aligned with the positioning hole 14, the operator presses down on the insertion rod 34 to secure the push rod 33. The rounded corners at the lower end of the insertion rod 34 facilitate smooth insertion of the insertion rod 34 into the positioning hole 14.

[0045] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 5 A first rubber pad 312 is connected to the side wall of the pressure plate 31 for abutting against one side wall of the sound insulation board 10 , and a second rubber pad 112 is connected to the side wall of the accommodating cavity 11 for abutting against the other side wall of the sound insulation board 10 .

[0046] In this embodiment, the second rubber pad 112 is fixed within the accommodating cavity 11, and the first rubber pad 312 is fixed to the pressure plate 31 and moves with the pressure plate 31 toward the second rubber pad 112 until it presses against a side wall of the sound insulation board 10. The sound insulation board 10 is compressed between the first rubber pad 312 and the second rubber pad 112. Due to the inherent elasticity of the first and second rubber pads 312, 112, they prevent damage to the sound insulation board 10. At the same time, the first and second rubber pads 312, 112 increase the contact friction between them and the sound insulation board 10, helping to maintain stable compression of the sound insulation board 10.

[0047] As a specific embodiment of the bridge construction sound insulation board transport trolley provided by the utility model, see Figure 1 The bottom of the vehicle body 1 is connected to four universal wheels 15, which are respectively arranged near the four corners of the vehicle body 1, and the rear end of the vehicle body 1 is connected to a handrail 16 extending rearward and upward.

[0048] In this embodiment, after securing the sound insulation panel 10 to the receiving cavity 11, the operator can then push the vehicle body 1 using the handrail 16 to transport the sound insulation panel 10. The provision of universal wheels 15 allows for flexible mobility of the vehicle body 1, making it easy to adapt to narrow construction sites. The two universal wheels 15 at the rear end are equipped with brakes to enhance the stability of the vehicle body 1 when it is stopped.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
