Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge detection, in particular to a sampling device for road and bridge detection. Background Art

[0002] The sampling device in road and bridge inspection is mainly used to collect samples of materials such as concrete and asphalt for laboratory analysis to ensure project quality.

[0003] Existing sampling devices for road and bridge inspections can be referenced in Chinese utility model patent publication number CN216771109U, which discloses a sampling device for road and bridge inspections. The sampling device comprises an annular mounting plate, the lower surface of which is fixedly connected to two symmetrically distributed sliding rods. The bottom ends of the sliding rods are fixedly connected to a fixed plate, the middle portion of which is inlaid with a threaded sleeve. A movable plate is disposed above the fixed plate, and both ends of the movable plate are provided with a slide groove that matches the sliding rods. A servo motor is inlaid in the middle of the movable plate, and the output shaft of the servo motor is fixedly connected to a screw rod. The utility model provides a mounting plate, a slide rod, a fixed plate, and a movable plate. The slide grooves at both ends of the movable plate cooperate with the slide rods, allowing the movable plate to slide vertically up and down. The servo motor and screw disposed in the middle of the movable plate cooperate with the threaded sleeve in the middle of the fixed plate, allowing the servo motor to drive the movable plate downward, thereby driving the sampling barrel downward.

[0004] When sampling, the servo motor drives the screw to rotate, which cooperates with the threaded sleeve to move the movable plate downward, thereby causing the servo motor and screw to move downward. The screw then drives the sampling barrel to rotate and move downward, allowing the crushing teeth at the bottom of the barrel to crush the sampling area. However, because the crushing teeth in the above-mentioned device are designed vertically, sampling objects of different materials and hardness may require different crushing forces and angles. Vertical crushing teeth are difficult to adapt to all types of sampling tasks, especially when encountering harder materials or materials with special structures, which may lead to sampling difficulties or poor sampling quality.

DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 5 A sampling device for road and bridge inspection includes a sampling mechanism 100 and a lifting mechanism 200 arranged on the left and right sides thereof. The sampling mechanism 100 includes a mounting plate 101:

[0025] Furthermore, a fixed platform 102 is fixedly connected to the bottom center of the mounting plate 101, and a No. 1 breaker rod 103 is rotatably connected to the center of the fixed platform 102. The No. 1 breaker rod 103 extends to the bottom of the fixed platform 102, and the top of the No. 1 breaker rod 103 passes through the mounting plate 101 and is rotatably connected thereto. A U-shaped plate 105 is fixedly connected to the top of the U-shaped plate 105, and a No. 1 motor 104 is fixedly connected to the top of the No. 1 motor 104. The output shaft of the No. 1 motor 104 extends to the bottom of the U-shaped plate 105 and is fixedly connected to the top of the No. 1 breaker rod 103. The No. 2 breaker rod 120 is rotatably connected to the left and right sides of the bottom of the No. 1 breaker rod 103.

[0026] The fixed platform 102 is located at the bottom center of the mounting plate 101 and is used to support the No. 1 breaker bar 103. When the No. 1 motor 104 is started, its output shaft drives the No. 1 breaker bar 103 to rotate, crushing the material in the sampling area, improving the crushing efficiency and crushing quality. Through the control of the lifting mechanism 200, the sampling mechanism 100 can move up and down, thereby adjusting the sampling depth and position to meet different sampling needs.

[0027] Furthermore, a No. 1 bevel gear 106 is fixedly sleeved on the surface of the No. 1 breaker rod 103, and a No. 2 bevel gear 107 is meshed and connected on both the left and right sides of the top of the No. 1 bevel gear 106. The inner walls of the two No. 2 bevel gears 107 are fixedly connected to a rotating rod 108. The two rotating rods 108 are rotatably set on the left and right sides of the top of the mounting plate 101 respectively, and a No. 1 pulley 109 is fixedly sleeved on the surface of one end of the two rotating rods 108 away from each other.

[0028] Furthermore, positioning blocks 111 are fixedly connected to the left and right sides of the bottom of the mounting plate 101, and the inner centers of the two positioning blocks 111 are rotatably connected to two horizontal threaded rods 110 with opposite threads. The two horizontal threaded rods 110 are rotatably connected to the left and right sides of the fixed platform 102 at one end close to each other, and the two horizontal threaded rods 110 are fixedly sleeved with a second pulley 112 on the surface of one end away from each other, and a belt 113 is connected for transmission between the first pulley 109 and the second pulley 112.

[0029] When motor 104 is activated, its output shaft drives breaker bar 103 to rotate. This rotation also causes bevel gear 106, affixed to its surface, to rotate. This rotation also causes bevel gear 106, meshing with it, to rotate the two bevel gears 107, converting vertical power into horizontal power. As bevel gear 107 rotates, so does a rotating rod 108 affixed to its inner wall. This rotation also causes pulley 109, affixed to one end of the bevel gear, to rotate. As pulley 109 rotates, it transmits power to pulley 112 via belt 113. As pulley 112 rotates, a horizontal threaded rod 110, affixed to one end of the bevel gear, also rotates.

[0030] Furthermore, the surfaces of the two horizontal threaded rods 110 are both threadedly connected with horizontal threaded blocks 115 . The two horizontal threaded blocks 115 are respectively arranged on the left and right sides of the fixing platform 102 and are slidably connected to the bottom of the mounting plate 101 .

[0031] Furthermore, horizontal limit rods 114 are slidably connected to the front and rear sides of the inner walls of the two horizontal threaded blocks 115. One end of the four horizontal limit rods 114 is fixedly connected to the left and right sides of the surface of the fixed platform 102, and the other end of the four horizontal limit rods 114 is fixedly connected to the side close to each other of the two positioning blocks 111.

[0032] Furthermore, the bottoms of the two horizontal threaded blocks 115 are fixedly connected to fixed plates 116, and the bottoms of the two fixed plates 116 are rotatably connected to the sides thereof away from each other with electric push rods 117. The two electric push rods 117 are tiltedly arranged at the bottoms of the two fixed plates 116, and the telescopic ends of the bottoms of the two electric push rods 117 are rotatably connected to protective covers 118.

[0033] Furthermore, the two protective covers 118 are tilted and arranged on one side close to each other at the bottom of the two fixed plates 116. The two protective covers 118 are rotatably connected to the bottom of the two fixed plates 116. The inner walls of the two protective covers 118 are fixedly connected to the No. 2 motor 119. The output shafts of the two No. 2 motors 119 are fixedly connected to the tilted No. 2 breaking rods 120. The two No. 2 breaking rods 120 extend to the outside of the protective cover 118 and are rotatably connected to it.

[0034] When horizontal threaded rod 110 rotates, threaded horizontal block 115 moves horizontally. Horizontal limit rod 114 limits the movement of horizontal block 115, ensuring its linear motion. When horizontal block 115 moves, fixed plate 116 attached to its base also moves. This movement changes the tilt angle of electric push rod 117. The telescopic movement of electric push rod 117 further adjusts the angle of protective cover 118. When motor 119 is activated, its output shaft rotates breaker bar 120. This rotation effectively crushes material in the sampling area, improving sampling efficiency.

[0035] Furthermore, the lifting mechanism 200 includes a No. 1 mounting frame 201 and a No. 2 mounting frame 202 which are symmetrically arranged on the left and right. The front side of the inner wall of the No. 1 mounting frame 201 is rotatably connected to a lifting threaded rod 203. The top of the lifting threaded rod 203 extends to above the top of the No. 1 mounting frame 201 and is fixedly connected to a No. 3 motor 204. The rear side of the inner wall of the No. 1 mounting frame 201 is fixedly connected to a No. 1 lifting limit rod 205. The front and rear sides of the inner wall of the No. 2 mounting frame 202 are fixedly connected to No. 2 lifting limit rods 206. The front end on the left side of the mounting plate 101 is threadedly connected to the lifting threaded rod 203. The rear end on the left side of the mounting plate 101 is slidingly connected to the No. 1 lifting limit rod 205. The front and rear surfaces on the right side of the mounting plate 101 are slidingly connected to the two No. 2 lifting limit rods 206.

[0036] When motor 3 204 is activated, its output shaft drives the lifting threaded rod 203 to rotate. As the lifting threaded rod 203 rotates, the left front end of the mounting plate 101, which is threadedly connected to it, moves up and down along the lifting threaded rod 203. The left rear end of the mounting plate 101 is slidably connected to the first lifting limit rod 205, ensuring that the mounting plate 101 remains stable during its up and down movement. The right front and back surfaces of the mounting plate 101 are slidably connected to the two second lifting limit rods 206, further ensuring the stability of the mounting plate 101 during its up and down movement.

[0037] The above are only preferred embodiments of the present invention and are 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.
