Description

Technical Field

[0001] This utility model relates to the field of walkway inspection technology, and specifically discloses a walkway surface defect inspection device. Background Technology

[0002] Walkways are an important accessory for automobiles and cranes. They are composed of thin steel plates and channel steel, with the channel steel typically welded to the underside of the thin steel plates to enhance the rigidity and strength of the walkway. As an operating platform for construction machinery, the walkway is primarily mounted on the crane frame, located on both sides of the crane chassis. It serves to support and protect the vehicle, facilitate operator movement, provide a safe passageway, and also contribute to the vehicle's aesthetics. When surface defects such as scratches, cracks, or abnormal protrusions and dents appear on the walkway, it not only affects its appearance but also significantly impacts its lifespan, potentially endangering the safety of operators.

[0003] Chinese Patent No. CN221124473U discloses a surface defect detection device for a walkway, including a base and a walkway. The top of the base has a groove, and a movable seat is slidably connected to the inner wall of the groove. A hydraulic push rod is fixedly connected to the top of the base, and the movable end of the hydraulic push rod is fixedly connected to the side wall of the movable seat. The top of the movable seat has symmetrical rectangular slots, and a motor is fixedly connected to the side wall of the movable seat. One end of a bidirectional lead screw passes through and rotates within the two rectangular slots. The advantages are: when the rollers contact the surface of the walkway, the hydraulic push rod drives the movable seat to move. When encountering uneven parts, because the rollers are always in contact with the surface of the walkway, the detector can move up and down synchronously with the rollers, ensuring that the detector and the surface of the walkway are always at a predetermined distance, improving the accuracy of the detection, facilitating the detection of surface defects on the walkway, and improving detection efficiency.

[0004] The aforementioned document uses a single-sided inspection method when detecting surface defects on a walkway, which requires multiple clamping and flipping of the walkway, easily causing surface scratches. This results in cumbersome operation and low inspection efficiency. Therefore, a walkway surface defect detection device is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a surface defect detection device for a walkway plate. The feeding mechanism facilitates loading and unloading, avoiding manual operation. The two detectors can simultaneously detect both sides of the walkway plate, thereby improving detection efficiency.

[0006] This utility model is implemented as follows: a surface defect detection device for a walkway includes a workbench, a fixed frame is fixedly connected to the upper end face of the workbench, a detector is symmetrically arranged at the upper and lower ends of the inner wall of the fixed frame, and outwardly extending fixed frames are fixedly connected to the left and right sides of the fixed frame. A clamping mechanism is provided on the inner wall of the two fixed frames, and a feeding mechanism located in front of the fixed frame is provided on the upper end face of the workbench.

[0007] The clamping mechanism includes an electric slide rail installed on the inner wall of the fixed frame, a movable plate slidably connected to the outer wall of the electric slide rail via a sliding sleeve, an electric push rod installed at the other end of the movable plate, and a positioning plate fixedly connected to the output end of the electric push rod.

[0008] The feeding mechanism includes a cavity opened inside the workbench and extending in the front-to-back direction, a threaded rod rotatably connected inside the cavity, a servo motor installed on the outer wall of the workbench and whose output end is fixedly connected to the threaded rod, a movable frame threaded to the outer wall of the threaded rod, and a feeding plate fixedly connected to the upper end face of the movable frame.

[0009] As a preferred embodiment of the surface defect detection device for a walkway according to this utility model, the feeding mechanism further includes a slide rod fixedly connected inside the cavity and arranged parallel to the threaded rod, and the moving frame and the slide rod are slidably connected.

[0010] As a preferred embodiment of the surface defect detection device for a walkway according to this utility model, the bearing surface of the feeding plate and the clamping surfaces of the two positioning plates are all provided with rubber pads with anti-slip texture.

[0011] As a preferred embodiment of the surface defect detection device for a walkway according to this utility model, the fixing frame is provided with through openings on both the front and rear sides.

[0012] As a preferred embodiment of the surface defect detection device for a walkway according to this utility model, the upper end surface of the worktable is provided with a through groove communicating with the cavity.

[0013] As a preferred embodiment of the surface defect detection device for a walkway according to this utility model, a controller is installed on the outer wall of the left fixed frame, and the detector, electric push rod, electric slide rail and servo motor are all electrically connected to the controller.

[0014] The beneficial effects of this utility model are:

[0015] 1. The moving frame drives the loading plate to move closer to the fixed frame until the loading plate moves the upper end of the table plate to the middle of the clamping mechanism. Then the clamping mechanism can clamp the table plate. Conversely, the loading mechanism can transport the inspected table plate forward, thereby facilitating loading and unloading and avoiding manual operation.

[0016] 2. The electric push rod pushes the two positioning plates closer together to clamp and position the walkway plate. Then, under the action of the electric slide rail, the moving plate drives the electric push rod, the positioning plate, and the clamped walkway plate to move backward. During the movement, the two detectors on the inside of the fixed frame simultaneously detect the upper and lower surfaces of the walkway plate. As the clamping mechanism drives the walkway plate to move, both sides of the walkway plate can be detected synchronously, thereby improving the detection efficiency. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-3 A surface defect detection device for a walkway includes a workbench 1, a fixed frame 3 fixedly connected to the upper end face of the workbench 1, a detector 301 symmetrically arranged at the upper and lower ends of the inner wall of the fixed frame 3, and outwardly extending fixed frames 302 fixedly connected to the left and right sides of the fixed frame 3. The inner walls of the two fixed frames 302 are provided with clamping mechanisms, and a feeding mechanism located in front of the fixed frame 3 is provided on the upper end face of the workbench 1.

[0024] The clamping mechanism includes an electric slide rail 303 installed on the inner wall of the fixed frame 302, a movable plate 304 slidably connected to the outer wall of the electric slide rail 303 via a sliding sleeve, an electric push rod 4 installed at the other end of the movable plate 304, and a positioning plate 401 fixedly connected to the output end of the electric push rod 4.

[0025] The feeding mechanism includes a cavity opened inside the workbench 1 and extending in the front-to-back direction, a threaded rod 201 rotatably connected inside the cavity, a servo motor 202 installed on the outer wall of the workbench 1 and whose output end is fixedly connected to the threaded rod 201, a movable frame 2 threadedly connected to the outer wall of the threaded rod 201, and a feeding plate 203 fixedly connected to the upper end face of the movable frame 2.

[0026] In this embodiment: the walkway plate to be tested is placed on the upper surface of the loading plate 203, and the servo motor 202 is started at the same time, so that the servo motor 202 drives the threaded rod 201 to rotate, causing the moving frame 2 to move the loading plate 203 towards the fixed frame 3, until the loading plate 203 moves the walkway plate on its upper surface to the middle of the clamping mechanism, and then the clamping mechanism can clamp the walkway plate. Conversely, the loading mechanism can transport the tested walkway plate forward, thereby achieving the effect of facilitating loading and unloading and avoiding manual operation.

[0027] The platform plate, moved to the middle of the clamping mechanism, can be moved by activating the electric push rod 4, which pushes the two positioning plates 401 closer together, causing the two positioning plates 401 to clamp and position the platform plate. Then, the controller controls the two electric slide rails 303 to work synchronously. Under the action of the electric slide rails 303, the moving plate 304 drives the electric push rod 4, the positioning plates 401, and the clamped platform plate to move backward. During the movement, the two detectors 301 (including a CCD vision inspection module and a laser rangefinder module) on the inner side of the fixed frame 3 simultaneously inspect the upper and lower surfaces of the platform plate. As the clamping mechanism moves the platform plate, both surfaces of the platform plate can be inspected simultaneously, thereby improving the inspection efficiency.

[0028] As a technical optimization of this utility model, the feeding mechanism also includes a slide rod fixedly connected inside the cavity and arranged parallel to the threaded rod 201, and the movable frame 2 and the slide rod are slidably connected.

[0029] In this embodiment, the movable frame 2 can be moved back and forth stably by means of a sliding rod.

[0030] As a technical optimization of this utility model, the bearing surface of the feeding plate 203 and the clamping surface of the two positioning plates 401 are both provided with rubber pads with anti-slip texture.

[0031] In this embodiment, the rubber pad layer can protect the walkway plate while increasing the stability of the walkway plate clamping.

[0032] As a technical optimization of this utility model, the front and rear sides of the fixing frame 3 are provided with through openings.

[0033] In this embodiment: through openings are provided on the front and rear sides of the fixing frame 3 to facilitate the smooth entry of the test platform into the fixing frame 3, and to be tested by the testing instrument 301.

[0034] As a technical optimization of this utility model, the upper end surface of the workbench 1 is provided with a through groove that communicates with the cavity.

[0035] In this embodiment: the through slot allows the movable frame 2 to move the loading plate 203 smoothly back and forth, completing the loading and unloading.

[0036] As a technical optimization of this utility model, a controller is installed on the outer wall of the left fixed frame 302, and the detector 301, electric push rod 4, electric slide rail 303 and servo motor 202 are all electrically connected to the controller.

[0037] In this embodiment, the controller can control the detector 301, electric push rod 4, electric slide rail 303 and servo motor 202 to work normally.

[0038] The working principle and usage process of this utility model are as follows: The walkway plate to be tested is placed on the upper surface of the loading plate 203. At the same time, the servo motor 202 is started, causing the servo motor 202 to drive the threaded rod 201 to rotate, causing the moving frame 2 to move the loading plate 203 towards the fixed frame 3 until the loading plate 203 moves the walkway plate on its upper surface to the middle of the clamping mechanism. Then, by starting the electric push rod 4, the electric push rod 4 pushes the two positioning plates 401 closer to each other, causing the two positioning plates 401 to clamp and position the walkway plate. Next, the controller controls the two electric slide rails 303 to work synchronously. Under the action of the electric slide rails 303, the moving plate 304 is moved... The electric push rod 4, the positioning plate 401, and the clamped walkway plate move backward. During the movement, the two detectors 301 (including a CCD vision inspection module and a laser rangefinder module) on the inner side of the fixed frame 3 simultaneously inspect the upper and lower surfaces of the walkway plate. As the clamping mechanism drives the walkway plate to move, both surfaces of the walkway plate can be inspected simultaneously. After the inspection is completed, the walkway plate moves forward with the clamping mechanism until it moves to the upper surface of the loading plate 203, causing the two positioning plates 401 to move away from each other and separate from the walkway plate. Then, the inspected walkway plate can be transported forward by the moving frame 2, thereby facilitating loading and unloading and avoiding manual operation.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
