[0037] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0038] The following further elaborates in detail on the construction environment noise monitoring vehicle of the present invention and its monitoring method in conjunction with the accompanying drawings and specific embodiments.

[0039] Please refer to Figures 1 to 6 As shown, the construction environment noise monitoring vehicle includes:

[0040] A floor 1 arranged in the horizontal direction, two first vertical plates 8 are connected in parallel at intervals at the bottom of the floor 1, and a second vertical plate 9 located between the two first vertical plates 8 and perpendicular to the first vertical plates 8 is connected to the bottom of the floor 1;

[0041] A noise detector 2, which is connected to the top of the floor 1;

[0042] Two spaced-apart rotating shafts 10 are provided. Both of the two rotating shafts 10 are perpendicular to the first vertical plate 8. First connection holes through which the two rotating shafts 10 pass and are rotatably connected are provided on both of the two first vertical plates 8. Both ends of each rotating shaft 10 extend out of the two first vertical plates 8 respectively and are detachably connected with rollers 7.

[0043] A driven shaft 13 is provided. The driven shaft 13 is perpendicular to the second vertical plate 9. A second connection hole through which the driven shaft 13 passes and is rotatably connected is provided on the second vertical plate 9. Both ends of the driven shaft 13 extend to the two rotating shafts 10 respectively. First bevel gears 11 are coaxially connected to both ends of the driven shaft 13 respectively. Second bevel gears 12 meshing with the corresponding first bevel gears 11 are coaxially connected to both of the two rotating shafts 10.

[0044] A braking assembly for restricting the rotation of the driven shaft 13 is provided. The braking assembly is movably mounted on the second vertical plate 9 and acts on the driven shaft 13.

[0045] By restricting the rotation of the driven shaft 13, the rotation of the two rotating shafts 10 is further restricted, and then the rolling of the rollers 7 is restricted, so as to realize the limit of the monitoring vehicle and ensure the stability of the monitoring vehicle.

[0046] Specifically, both between the rotating shaft 10 and the two first vertical plates 8 are connected through first bearings. The first bearings are connected in the corresponding first connection holes. Between the driven shaft 13 and the second vertical plate 9 are connected through second bearings. The second bearings are connected in the second connection holes.

[0047] By providing the first bearings and the second bearings, the rotation stability of the rotating shaft 10 and the driven shaft 13 is improved.

[0048] Preferably, the braking assembly includes:

[0049] A fixed collar 15 coaxially sleeved outside the driven shaft 13. The first end of the fixed collar 15 is fixed to the second vertical plate 9. A brake disc 14 is sleeved and fixed at a position corresponding to the second end of the fixed collar 15 on the driven shaft 13.

[0050] A plurality of claws 16 arranged at intervals along the circumferential direction of the fixed collar 15 and extending out of the second end of the fixed collar 15 along the axial direction of the fixed collar 15. A first spring 22 is connected between each claw 16 and the fixed collar 15. The plurality of claws 16 are connected to the fixed collar 15 in a relatively openable and closable manner. When the plurality of claws 16 are in a closed state, the plurality of claws 16 relatively clamp the outer periphery of the brake disc 14 to restrict the rotation of the brake disc 14. When the plurality of claws 16 are in an open state, the plurality of claws 16 are separated from the brake disc 14 to release the rotation restriction of the brake disc 14, and the first spring 22 is in a reset state.

[0051] A driving member for synchronously driving a plurality of the jaws 16 to open and close.

[0052] By providing the first spring 22, it is avoided that the jaw 16 approaches the brake disc 14 due to its own gravity factor.

[0053] Specifically, a plurality of pairs of ear plates 17 are connected to the outer periphery of the fixed collar 15 at intervals. A jaw 16 is rotatably connected between each pair of the ear plates 17. A space for accommodating the corresponding jaw 16 is formed between each pair of the ear plates 17. Each pair of the ear plates 17 and the corresponding jaw 16 are connected by a pin shaft. Through holes for the pin shaft to pass through are provided in each pair of the ear plates 17 and in the middle of the corresponding jaw 16.

[0054] Preferably, the driving member includes:

[0055] A bushing 19, which is rotatably sleeved between the driven shaft 13 and the fixed collar 15. One end of the bushing 19 is rotatably connected to the second vertical plate 9;

[0056] A plurality of push rods 18, and the plurality of push rods 18 are connected to the plurality of jaws 16 in one-to-one correspondence. A plurality of jack holes 23 for the plurality of push rods 18 to be inserted in one-to-one correspondence are provided on the fixed collar 15;

[0057] A ratchet wheel 20 for synchronously pushing a plurality of the push rods 18 to enable the plurality of jaws 16 to open and close synchronously. The ratchet wheel 20 is connected to the outer periphery of the bushing 19. When the plurality of jaws 16 are in a closed state, the plurality of push rods 18 are all abutted against positions on the ratchet wheel 20 relatively far from the ratchet wheel axis. When the plurality of jaws 16 are in an open state, the plurality of push rods 18 are all abutted against positions on the ratchet wheel 20 relatively close to the ratchet wheel axis;

[0058] A grip rod 6 for driving the bushing 19 to rotate, and the grip rod 6 is connected to the bushing 19.

[0059] By the rotation of the ratchet wheel 20, a plurality of the push rods 18 are synchronously pushed, and a plurality of the jaws 16 are driven to open and close synchronously, so as to limit or release the limit on the brake disc 14. The structure is simple and the operation is convenient.

[0060] Specifically, the bushing 19 is separated from the driven shaft 13, and the bushing 19 is separated from the fixed collar 15.

[0061] By separating the bushing 19 from the driven shaft 13, it is avoided that the rotation of the bushing 19 affects the rotation of the driven shaft 13. By separating the bushing 19 from the fixed collar 15, a rotation space is left for the ratchet wheel 20, and an insertion space is left for the push rod 18.

[0062] Preferably, the grip rod 6 is fixedly connected to the bushing 19 along the radial direction of the bushing 19. One end of the grip rod 6 that is relatively far away from the bushing 19 extends out of the bottom plate 1. A through groove 5 is axially formed in the bottom plate 1 for the grip rod 6 to pass through and slide. When the grip rod 6 slides to the first end of the through groove 5, a plurality of the claws 16 are in an open state. When the grip rod 6 slides to the second end of the through groove 5, a plurality of the claws 16 are in a closed state. The grip rod 6 and the fixed collar 15 are arranged in a dislocation manner.

[0063] The rotation of the bushing 19 is controlled by the swing of the grip rod 6, which is simple in operation and saves costs. By reciprocating the grip rod 6 at both ends of the through groove 5, the monitoring vehicle is braked and the braking is released.

[0064] Specifically, a plurality of connecting rods 21 are spaced and connected to the fixed collar 15, and the plurality of connecting rods 21 are connected to the second vertical plate 9.

[0065] By connecting a plurality of the connecting rods 21 at intervals between the fixed collar 15 and the second vertical plate 9, a gap for the grip rod 6 to pass through is left between the fixed collar 15 and the second vertical plate 9, avoiding the direct connection between the fixed collar 15 and the second vertical plate 9 and affecting the passing through of the grip rod 6.

[0066] Preferably, limiting members 24 for limiting the grip rod 6 are connected to both ends of the through groove 5.

[0067] By providing the limiting members 24, after the grip rod 6 moves into place, the grip rod 6 is prevented from shaking and affecting the braking effect.

[0068] Specifically, the diameter of the grip rod 6 is adapted to the through groove 5. The limiting member 24 includes two relatively arranged balls. Embedding grooves for the two balls to be embedded are respectively formed on opposite side walls of the through groove 5. The distance between the embedding groove and the corresponding end of the through groove 5 is equal to the diameter of the grip rod 6. Each ball and the corresponding embedding groove are connected by a second spring. In the reset state of the second spring, the two balls block in the through groove 5 and the distance between the two balls is less than the diameter of the grip rod 6. In the compression limit state of the second spring, the balls are completely embedded in the corresponding embedding grooves.

[0069] When the grip rod 6 moves to the two balls, the two balls will be squeezed and completely embedded in the corresponding embedding grooves. After the grip rod 6 moves to the end of the through groove 5, the two balls rebound and clamp and limit the grip rod 6. The structure is simple and highly practical.

[0070] Preferably, a noise sensor 3 is connected to the top of the noise detector 2, and the noise detector 2 is connected to the bottom plate 1 through a support rod 4.

[0071] The noise sensor 3 receives the noise and transmits it to the noise detector 2, and the noise detector 2 detects and evaluates the received noise.

[0072] Specifically, the support rod 4 is a telescopic rod.

[0073] By setting the support rod 4 as a telescopic rod, it is convenient to monitor the noise at positions with different heights, improving the practicability.

[0074] A monitoring method for a construction environment noise monitoring vehicle includes the steps:

[0075] Step 1: Provide the above-mentioned construction environment noise monitoring vehicle and move it into position;

[0076] Step 2: Control the braking component to limit the rotation of the driven shaft 13, thereby restricting the rolling of the roller 7;

[0077] Step 3: Use the noise detector 2 to detect and evaluate the on-site noise.
