Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, and more specifically to an anti-slip pattern device for a manhole cover. Background Art

[0002] The anti-slip texture of the manhole cover has a great relationship with its friction coefficient. If the texture of the manhole cover is qualified, it means that the anti-slip performance is qualified. Most of the existing methods for inspecting the anti-slip texture of the manhole cover use photos and visual identification. Some key textures that are not easy to find are worn and may not be effectively detected, resulting in reduced anti-slip performance of the manhole cover. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a device for inspecting the anti-slip patterns of manhole covers, so as to solve the problem that the existing means of inspecting the anti-slip patterns of manhole covers in the above-mentioned background technology mostly use photographs and visual identification, and some key patterns that are not easy to find are worn and may not be effectively detected, resulting in a reduction in the anti-slip performance of the manhole cover.

[0004] The utility model provides the following technical scheme: it comprises an inspection equipment body, wherein a movable wheel is movably mounted on the bottom end of the inspection equipment body through a rotating shaft, the number of the movable wheels is four, a control panel is movably mounted on one side of the top end of the inspection equipment body through a rotating shaft, a friction measuring plate is movably mounted on the bottom end of the inspection equipment body, four groups of telescopic rods are arranged on the top end of the friction measuring plate, the top end of the telescopic rods is fixedly connected to the bottom end of the inspection equipment body, the friction measuring plate and the telescopic rods are electrically connected to the control panel through wires, and support rods are fixedly mounted on the front and rear of the inspection equipment body, and a push-pull handle is simultaneously connected to the support rods. When in use, the telescopic rod is started to drive the friction measuring plate to move downward and contact the top of the manhole cover. Then the user holds the push-pull handle and pushes the main body of the inspection device, so that the moving wheel drives the main body of the inspection device and the friction measuring plate to reciprocate and rub on the top of the manhole cover. The main body of the friction measuring plate is a portable friction coefficient tester, which transmits the instantaneous friction force data to the control panel through power supply. The user can judge whether the friction force is too small by observing these data. If it is too small, it means that the manhole cover is seriously worn. In actual use, it effectively solves the problem that most of the existing anti-slip texture inspection methods of manhole covers use photos and distinguish them with the naked eye. Some key textures that are not easy to find are worn and may not be effectively detected, resulting in reduced anti-slip performance of the manhole cover.

[0005] Furthermore, a pressure sensor is fixedly installed at the bottom end of the telescopic rod, an adsorption magnet is arranged at the bottom end of the pressure sensor, an adsorption magnet is arranged at the top end of the friction measuring plate, and the polarities of the two adsorption magnets are opposite, and the pressure sensor is electrically connected to the control panel through a wire. During use, since friction and pressure are positively correlated, in order to prevent the friction measuring plate from being squeezed too much against the ground when the telescopic rod drives the friction measuring plate to move downward, resulting in incorrect friction detection, the user can judge whether the vertical pressure on the friction measuring plate is too large by the pressure measured by the pressure sensor, and the user can quickly replace and disassemble the friction measuring plate by separating the adsorption magnet between the friction measuring plate and the pressure sensor.

[0006] Furthermore, a water storage tank is provided inside the inspection device body, a water filling hole is provided on the water storage tank, a water spray nozzle is connected to one side of the inspection device body through a water pump, and the water pump on the water spray nozzle is electrically connected to the control panel. When in use, the user can turn on the water pump of the water spray nozzle to spray the water in the water storage tank onto the surface of the manhole cover to simulate whether the friction of the manhole cover is qualified on rainy days.

[0007] Furthermore, a panel base is provided at the top of the inspection device body, the panel base is located at the bottom of the control panel, and a storage slot is provided on the panel base. When in use, the user can store the control panel into the storage slot of the panel base by rotating the control panel to protect the control panel.

[0008] Furthermore, a mounting slot is provided inside the inspection device body, and a plurality of counterweights are movably placed in the mounting slot. When in use, the user can further simulate the pressure of the friction measurement plate by placing different numbers of counterweights on the inspection device body, so as to simulate the friction when people of different weights walk on the manhole cover.

[0009] Furthermore, the main body material of the inspection device body is an aluminum alloy metal plate. When in use, the inspection device body made of the aluminum alloy metal plate has a lighter weight and better corrosion resistance.

[0012] 2. The utility model is provided with a pressure sensor and an adsorption magnet. When in use, since friction and pressure are positively correlated, in order to prevent the friction measuring plate from being squeezed too much between the friction measuring plate and the ground when the telescopic rod drives the friction measuring plate to move downward, resulting in incorrect friction force detection, the user can judge whether the vertical pressure on the friction measuring plate is too large by the pressure measured by the pressure sensor. At the same time, the user can quickly replace and disassemble the friction measuring plate by separating the adsorption magnet between the friction measuring plate and the pressure sensor.
