Description

Technical Field

[0001] The invention belongs to the technical field of infrared laser detection, and in particular relates to an infrared laser ground leveling detection machine for construction engineering. Background Art

[0002] The infrared laser ground leveling detector is a high-precision device used to detect ground levelness. It combines infrared technology and laser scanning technology to quickly and accurately evaluate whether the ground surface is flat. It is widely used in engineering fields such as construction, roads, and bridges. During operation, the detector can calculate the height change of the ground based on the reflection characteristics of the laser, by measuring the time difference or reflection intensity of the laser reflected from the ground, and finally evaluate the flatness of the ground.

[0013] Preferably, a steering wheel and a plurality of steering sleeves are fixedly connected to the U-shaped frame, and the traction rope is fixedly connected to the arc-shaped tooth groove through a plurality of steering sleeves and a steering wheel in sequence.

[0014] Preferably, the two moving rollers in the moving plate below the arc-shaped tooth grooves are both installed inside the moving plate through one-way bearings.

[0015] Preferably, the U-shaped frame is also provided with a cleaning mechanism, including a mounting block fixedly connected to the upper end of the U-shaped frame, a bidirectional screw rod passing through the mounting block and rotatably connected, the upper end of the U-shaped frame is rotatably connected to a second transmission rod, both ends of the second transmission rod are fixedly connected to a bevel gear, the rotating rod and the bidirectional screw rod are fixedly connected to a bevel gear ring, each of the bevel gears is meshed with the bevel gear ring at a corresponding position, the spiral directions of the threads on both sides of the bidirectional screw rod are opposite, the threads on both sides of the bidirectional screw rod are threadedly connected with a slider, the slider is slidably connected to the upper wall of the U-shaped frame, an extension rod is fixedly connected to the side wall of the slider, the part of the extension rod extending to the lower end of the U-shaped frame is fixedly connected with an elastic telescopic rod, the bottom end of the elastic telescopic rod is fixedly connected with a cleaning plate, and the lower wall of the cleaning plate is provided with bristles.

[0017] Compared with existing technologies, the advantages of this infrared laser ground leveling detection machine for construction projects are:

[0018] 1. The present invention is provided with a self-propelled mechanism. When in use, when the moving block drives the infrared laser generator to move horizontally to the left, the detection work is completed. At this time, the movement of the tooth plate will cause the winding wheel to start to rotate clockwise, and the traction rope pulls the arc-shaped tooth groove to swing upward, driving the detection machine to move forward as a whole.

When the moving block drives the infrared laser generator to move horizontally to the right to detect the ground, the rotation of the arc-shaped tooth groove cannot drive the moving roller to rotate due to the setting of the one-way bearing. During the detection process, the arc-shaped tooth groove is automatically reset to facilitate the next displacement of the U-shaped frame. In this process, the U-shaped frame will not move and reset to the initial position, thereby ensuring the automatic walking function of the detection machine.

[0020] 3. The present invention sets a cleaning mechanism. When the U-shaped frame periodically performs the detection function and the self-propelled function, the rotating rod will rotate back and forth in the opposite direction, thereby driving the bidirectional lead screw to rotate back and forth in the opposite direction through two bevel gears, two bevel gear rings and a second transmission rod, so that the two sliders can drive the two cleaning plates away from each other when the U-shaped frame is self-propelled, and automatically clean the detection position during self-propelled, so as to avoid garbage and debris at the detection position blocking the line of sight of the infrared laser generator, thereby improving the comprehensiveness of the detection.

[0021] 4. The present invention provides a trapezoidal guide block and a guide wheel. When the two cleaning plates are cleaning the detection position, when the two cleaning plates are farthest away from each other, the guide wheel moves from the position with a larger width on the trapezoidal guide block to the position with a smaller width, so that the elastic telescopic rod can drive the cleaning plate to move upward at an angle, so that the bristles under the cleaning plate can be passed through the scraping plate, and the scraping plate can scrape and clean the garbage and debris swept out by the bristles on the cleaning plate, thereby further improving the cleaning effect of the cleaning plate on the detection position.

DETAILED DESCRIPTION

[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0029] Example: Refer to Figures 1 to 5 , an infrared laser ground leveling detection machine for construction engineering, comprising:

[0030] A U-shaped frame 1, two support rods 11 are fixedly connected to the lower ends of both sides of the U-shaped frame 1, and a moving plate 12 is fixedly connected to the lower ends of the two support rods 11. The lower ends of the moving plates 12 are rotatably connected to two symmetrically arranged moving rollers 13. A detection mechanism 2 for detecting the flatness of the construction engineering floor is provided in the U-shaped frame 1, and the detection mechanism 2 includes a moving block 21 connected to the lower wall of the U-shaped frame 1 and reciprocatingly slidably in the horizontal direction;

[0031] Specifically, the detection mechanism 2 also includes a reciprocating screw 22 rotatably connected between the inner walls on both sides of the U-shaped frame 1, the moving block 21 is threadedly connected to the reciprocating screw 22, the lower end of the moving block 21 is fixedly connected with an infrared laser generator 23 for emitting an infrared laser beam, the peripheral side of the infrared laser generator 23 is fixedly connected with an infrared laser receiver 24 for receiving the infrared laser beam, and a motor 25 for driving the reciprocating screw 22 is fixedly connected to the outer wall of one side of the U-shaped frame 1. In actual use, the reciprocating screw 22 can be driven to rotate by the motor 25, and the moving block 21 can be further driven to reciprocate horizontally along the reciprocating screw 22, so that the infrared laser generator 23 and the infrared laser receiver 24 at the lower end of the moving block 21 are reciprocated horizontally. The infrared laser generator 23 emits an infrared laser beam. When the laser beam is irradiated to the ground of the construction project, part of the laser will be reflected back by the ground, and the reflected laser signal will be captured by the infrared laser receiver 24, thereby realizing the flatness detection of the ground.

[0032] Specifically, a strip limit groove 4 is opened at the upper end of the U-shaped frame 1, and the moving block 21 is slidably connected to the inner wall of the strip limit groove 4. The strip limit groove 4 can limit the moving block 21, so that the moving block 21 can only move back and forth in the horizontal direction to avoid motion interference.

[0033] The self-propelled mechanism 3 is used to automatically move the U-shaped frame 1 forward to the next detection position after the flatness detection of the construction project ground is completed. The self-propelled mechanism 3 includes a rotating rod 31 rotatably connected to the upper end of the U-shaped frame 1, and a driving gear 32 is fixedly installed on the rotating rod 31. The portion of the moving block 21 extending above the U-shaped frame 1 is fixedly connected to a toothed plate 33, and the toothed plate 33 and the driving gear 32 are meshed with each other. The top of the rotating rod 31 is fixedly connected to a winding wheel 34, and a traction gear is wound on the winding wheel 34. Rope 35, the upper end of one of the movable plates 12 is rotatably connected to a large gear 36, the middle positions of the two movable rollers 13 are fixedly connected to small gears 37, the two small gears 37 are respectively meshed with the two sides of the large gear 36, a first transmission rod 38 is rotatably connected between the two support rods 11, an arc-shaped tooth groove 39 is fixedly connected to the first transmission rod 38, the arc-shaped tooth groove 39 is meshed with the upper end of the large gear 36, and the end of the traction rope 35 away from the winding wheel 34 is fixedly connected to the arc-shaped tooth groove 39.

[0034] Specifically, a steering wheel 5 and a plurality of steering sleeves 51 are fixedly connected to the U-shaped frame 1, and the traction rope 35 is fixedly connected to the arc-shaped tooth groove 39 through a plurality of steering sleeves 51 and a steering wheel 5 in succession. The plurality of steering sleeves 51 and a steering wheel 5 can guide the traction rope 35, ensuring that when the winding wheel 34 reels in or releases the traction rope 35, the traction rope 35 can stably pull the arc-shaped tooth groove 39 to swing upward or downward.

[0035] In view of the problem that the staff is required to move the detection machine to the next detection position in the prior art, which not only increases the workload of the staff but also reduces the detection efficiency of the construction project ground, the present invention sets a self-propelled mechanism 3. When in use, when the moving block 21 drives the infrared laser generator 23 to move horizontally to the left, the detection work is completed. At this time, the movement of the tooth plate 33 will drive the rotating rod 31 to rotate clockwise through the driving gear 32, so that the winding wheel 34 starts to rotate clockwise, so that the traction rope 35 is wound up by the winding wheel 34, and the arc-shaped tooth groove 39 is further pulled upward by the traction rope 35, so that the large gear 36 can drive the two moving rollers 13 on the same side to rotate through the small gear 37, and drive the detection machine as a whole to move forward through the U-shaped frame 1. After each detection is completed, the detection machine is automatically moved forward a certain distance, and can be automatically moved to the next detection position after each detection is completed, reducing the need for manual intervention and reducing workload, while improving detection efficiency and automation level.

[0036] In addition, the two moving rollers 13 in the moving plate 12 below the arc-shaped tooth groove 39 are both installed inside the moving plate 12 through a one-way bearing. Through the one-way bearing, when the moving block 21 drives the infrared laser generator 23 to move horizontally to the right to detect the ground, the movement of the tooth plate 33 will drive the rotating rod 31 to rotate counterclockwise through the driving gear 32, so that the winding wheel 34 starts to rotate counterclockwise, so that the traction rope 35 is released by the winding wheel 34, and the arc-shaped tooth groove 39 swings downward through the release of the traction rope 35. Specifically, the arc-shaped tooth groove 39 A counterweight is arranged inside, so that the arc-shaped tooth groove 39 can swing downward to the initial position under the action of gravity. Due to the arrangement of the one-way bearing, the swing of the arc-shaped tooth groove 39 cannot drive the movable roller 13 to rotate. During the detection process, the arc-shaped tooth groove 39 is automatically reset to facilitate the next displacement of the U-shaped frame 1, and the U-shaped frame 1 will not move and reset to the initial position during this process, thereby ensuring the automatic walking function of the detection machine and avoiding vibration or position displacement caused by the movement of the U-shaped frame 1 during the detection process, so that the data during the detection process is more accurate and stable.

[0037] The U-shaped frame 1 is also provided with a cleaning mechanism 6 controlled by the self-propelled mechanism 3, which is used to clean the detection position when the U-shaped frame 1 is moving. The cleaning mechanism 6 includes a mounting block 61 fixedly connected to the upper end of the U-shaped frame 1, and a bidirectional screw rod 62 is rotatably connected to the mounting block 61. The upper end of the U-shaped frame 1 is rotatably connected to a second transmission rod 63, and both ends of the second transmission rod 63 are fixedly connected to bevel gears 64. The rotating rod 31 and the bidirectional screw rod 62 are fixedly connected to bevel gear rings 65. Each bevel gear 64 are meshed with the bevel gear ring 65 at the corresponding position, the spiral directions of the threads on both sides of the bidirectional screw rod 62 are opposite, and the threads on both sides of the bidirectional screw rod 62 are threadedly connected with sliders 66, and the sliders 66 are linearly slidably connected to the upper wall of the U-shaped frame 1, and the side walls of the sliders 66 are fixedly connected with extension rods 67, and the part of the extension rods 67 extending to the lower end of the U-shaped frame 1 is fixedly connected with an elastic telescopic rod 68, and the bottom end of the elastic telescopic rod 68 is fixedly connected with a cleaning plate 69, and the lower wall of the cleaning plate 69 is provided with bristles.

[0038] In view of the problem that the ground at the detection position cannot be cleaned in the prior art, the garbage and debris on the ground will block the line of sight of the infrared laser generator, resulting in the inability to detect the area, thereby causing the loss of detection data and reducing the comprehensiveness of the detection, the present invention sets a cleaning mechanism 6, when the U-shaped frame 1 periodically performs the detection function and the self-propelled function, the rotating rod 31 will rotate back and forth in the opposite direction, thereby driving the two-way screw rod 62 to rotate back and forth in the opposite direction through two bevel gears 64, two bevel gear rings 65 and a second transmission rod 63, so that the two sliders 66 can move away from each other when the U-shaped frame 1 is self-propelled, and drive the two cleaning plates 69 to move away from each other through the extension rod 67 and the elastic telescopic rod 68, sweeping the garbage and debris at the detection position to both sides, automatically cleaning the detection position during self-propelled, avoiding the garbage and debris at the detection position from blocking the line of sight of the infrared laser generator, improving the comprehensiveness of the detection, and at the same time making the two sliders 66 move closer to each other when the U-shaped frame 1 is detected, so as to facilitate the continued cleaning of the detection position during the next self-propelled.

[0039] It is worth mentioning that the lower end of the U-shaped frame 1 is fixedly connected to a trapezoidal guide block 7, and the rod body on the lower side of the elastic telescopic rod 68 is rotatably connected to a guide wheel 71, and the guide wheel 71 rolls in contact with the trapezoidal guide block 7. The lower end of one of the movable plates 12 is fixedly connected to a plurality of scraping plates 72 distributed in a linear array, and the distance between two adjacent scraping plates 72 is the same as the diameter of the bristles. By setting the trapezoidal guide block 7 and the guide wheel 71, when the two cleaning plates 69 clean the detection position, when the two cleaning plates 69 are farthest away from each other, , so that the guide wheel 71 moves from the position with larger width on the trapezoidal guide block 7 to the position with smaller width, so that the elastic telescopic rod 68 can drive the cleaning plate 69 to move upward at an angle under the action of the internal elastic element, so that the bristles under the cleaning plate 69 can pass over the scraping plate 72, so that the bristles can be inserted between two adjacent scraping plates 72, and move upward to scrape off the garbage and debris stuck on the bristles, thereby cleaning the bristles on the cleaning plate 69 and further improving the cleaning effect of the cleaning plate 69 on the detection position.

[0040] The present invention can be explained by the following operation mode:

[0041] The reciprocating screw 22 is driven to rotate by the motor 25, driving the moving block 21 to reciprocate horizontally along the reciprocating screw 22, so that the infrared laser generator 23 and the infrared laser receiver 24 at the lower end of the moving block 21 are reciprocated horizontally. The infrared laser generator 23 emits an infrared laser beam. When the laser beam irradiates the ground of the construction project, part of the laser will be reflected back by the ground, and the reflected laser signal will be captured by the infrared laser receiver 24, so as to detect the flatness of the ground of the construction project and realize the detection function;

[0042] When the moving block 21 drives the infrared laser generator 23 to move horizontally to the left, the detection work is completed. At this time, the movement of the tooth plate 33 will drive the rotating rod 31 to rotate clockwise through the driving gear 32, so that the winding wheel 34 starts to rotate clockwise, so that the traction rope 35 is wound by the winding wheel 34, and the arc-shaped tooth groove 39 is further pulled upward by the traction rope 35, so that the large gear 36 can drive the two moving rollers 13 on the same side to rotate through the small gear 37, and drive the detection machine as a whole to move forward through the U-shaped frame 1, so as to realize the self-propelled function;

[0043] When the moving block 21 drives the infrared laser generator 23 to move horizontally to the right to detect the ground, the movement of the tooth plate 33 will drive the rotating rod 31 to rotate counterclockwise through the driving gear 32, so that the winding wheel 34 starts to rotate counterclockwise, so that the traction rope 35 is released by the winding wheel 34, and the arc-shaped tooth groove 39 swings downward through the release of the traction rope 35. Due to the one-way bearing, the swing of the arc-shaped tooth groove 39 cannot drive the moving roller 13 to rotate. During the detection process, the arc-shaped tooth groove 39 is automatically reset to facilitate the next displacement of the U-shaped frame 1, ensuring the subsequent displacement of the U-shaped frame 1.

[0044] When the U-shaped frame 1 periodically performs the detection function and the self-propelled function, the rotating rod 31 will rotate back and forth in the opposite direction, thereby driving the two-way screw rod 62 to rotate back and forth in the opposite direction through the two bevel gears 64, the two bevel gear rings 65 and a second transmission rod 63, so that the two sliders 66 can move away from each other when the U-shaped frame 1 is self-propelled, driving the two cleaning plates 69 to move away from each other, and sweeping the garbage and debris at the detection position to both sides. When the two cleaning plates 69 move away from each other to the farthest ends, the guide wheel 71 moves from the position with a larger width on the trapezoidal guide block 7 to the position with a smaller width, so that the elastic telescopic rod 68 can drive the cleaning plate 69 to move upwardly at an angle under the action of the internal elastic element, so that the bristles under the cleaning plate 69 can be stroked from the scraping plate 72, and the garbage and debris swept out by the bristles on the cleaning plate 69 are scraped and cleaned by the scraping plate 72, thereby completing the cleaning work of the cleaning plate 69.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
