Description

Technical Field

[0001] This utility model relates to the technical field of manhole cover installation auxiliary equipment, and in particular to a road manhole cover installation device. Background Technology

[0002] Manhole covers are used to cover deep wells on roads to prevent people or objects from falling in. They can be classified by material, such as metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers, and are widely used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] For example, Chinese patent CN216403782U discloses an auxiliary installation device for manhole covers for municipal roads, including a loading frame, a movable wheel at the bottom corner of the loading frame, a supporting foot on the loading frame corresponding to the movable wheel, a first displacement module at the middle of the rear side of the end of the loading frame, a second displacement module at the end of the first displacement module, a third displacement module at the end of the mounting bracket, and a clamping component installed on the loading plate.

[0004] Although the aforementioned patents have solved the problems of high manual labor intensity and low safety efficiency during manhole cover installation by using displacement modules and clamping components, the manhole cover is fixed by clamps when it is moved. When the manhole cover moves above the manhole seat, the clamps will block the outer ring surface of the manhole cover. When the clamps are released and the manhole cover falls, the manhole cover will generate a large impact force on the manhole seat, which can easily cause damage to the manhole seat. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the existing technology where manhole covers are fixed by clamps when moving. When the manhole cover moves above the manhole seat, the clamps will block the outer ring surface of the manhole cover. When the clamps are released and the manhole cover falls, the manhole cover will exert a large impact force on the manhole seat, which will easily cause damage to the manhole seat. Therefore, a road manhole cover installation device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a road manhole cover installation device, comprising a frame, an auxiliary frame fixedly connected to one side of the frame, an installation mechanism provided on one side of the auxiliary frame, the installation mechanism comprising a top plate, an adjusting plate and a clamp, a fixing rod fixedly connected to the bottom of the top plate, the bottom of the fixing rod being fixedly connected to the adjusting plate, and a second connector installed at the bottom of the adjusting plate, a first connector rotatably connected to one side of the second connector, a first connector fixedly connected to one side of the first connector, a threaded rod threadedly connected to the adjusting plate, one end of the threaded rod being rotatably connected to the frame, an output shaft of a motor fixedly connected to the top of the threaded rod, and the bottom of the motor being fixedly connected to the frame.

[0007] Preferably, a hydraulic cylinder is fixedly connected to the bottom of the adjusting plate, a pressing plate is fixedly connected to the bottom of the hydraulic cylinder, and a buffer pad is fixedly connected to the bottom of the pressing plate.

[0008] Preferably, the hydraulic cylinder is electrically connected to an electrical control box, and the bottom of the electrical control box is fixedly connected to the adjustment plate.

[0009] Preferably, one side of the top plate is slidably connected to the frame, a guide rod is inserted through the top plate, and a support plate is fixedly connected to the bottom of the guide rod.

[0010] Preferably, the support plate has an arc-shaped hole at the top and the bottom of the support plate is fixedly connected to the frame.

[0011] Preferably, an electric push rod is fixedly connected to one side of the frame, a detection frame is fixedly connected to one end of the electric push rod, one side of the detection frame is slidably connected to the frame, and an infrared ranging sensor is fixedly connected to one side of the detection frame.

[0012] Preferably, a slider is fixedly connected to the bottom of the frame, a guide rail is slidably connected to the bottom of the slider, and a pin is inserted between the top of the guide rail and the slider.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the top of the second connector is fixedly connected to the adjusting plate, and the adjusting plate is connected to the threaded rod by a thread. The rotation of the threaded rod drives the adjusting plate to descend until the bottom of the manhole cover is inserted into the manhole seat. Then the first connector rotates to separate the clamp from the manhole cover, realizing the initial installation of the manhole cover, reducing the impact force of the manhole cover on the manhole seat, and reducing the damage inside the manhole seat. The hydraulic cylinder drives the pressing plate to move down and pressurize the manhole cover, which can improve the fit between the manhole cover and the manhole seat and reduce the height difference between the manhole cover and the manhole seat after installation.

[0015] 2. In this utility model, the two ends of the electric push rod are fixedly connected to the detection frame and the machine frame, respectively. An infrared distance sensor is fixedly connected to one side of the detection frame. The detection frame is driven to move along the machine frame by the electric push rod. The infrared distance sensor detects the distance between the manhole cover and the detection frame. Based on the detection result, it can be determined whether there is a deviation in the current placement position of the device. The guide rail can guide the movement of the machine frame, thereby moving the manhole cover above the manhole cover and improving the accuracy of the position when installing the manhole cover.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: A road manhole cover installation device includes a frame 8, an auxiliary frame 9 fixedly connected to one side of the frame 8, and an installation mechanism provided on one side of the auxiliary frame 9. The installation mechanism includes a top plate 1, an adjusting plate 11, and a gripper 12. A fixing rod 18 is fixedly connected to the bottom of the top plate 1, and the bottom of the fixing rod 18 is fixedly connected to the adjusting plate 11. A second connector 15 is installed at the bottom of the adjusting plate 11. A first connector 14 is rotatably connected to one side of the second connector 15, and one side of the first connector 14 is fixedly connected to the gripper 12. A threaded rod 13 is threadedly connected to the adjusting plate 11, and one end of the threaded rod 13 is connected to the frame. The frame 8 is rotatably connected. The output shaft of the motor 10 is fixedly connected to the top of the threaded rod 13. The bottom of the motor 10 is fixedly connected to the frame 8. The bottom of the adjusting plate 11 is fixedly connected to the hydraulic cylinder 16. The bottom of the hydraulic cylinder 16 is fixedly connected to the pressing plate 19. The bottom of the pressing plate 19 is fixedly connected to the buffer pad. The hydraulic cylinder 16 is electrically connected to the electrical control box 17. The bottom of the electrical control box 17 is fixedly connected to the adjusting plate 11. One side of the top plate 1 is slidably connected to the frame 8. A guide rod 2 is inserted through the top plate 1. The bottom of the guide rod 2 is fixedly connected to the support plate 3. The support plate 3 is fixedly connected to the frame 8.

[0024] The auxiliary frame 9 provides support and reinforcement for one side of the frame 8. The auxiliary frame 9 and frame 8 guide the lifting and lowering of the top plate 1. The fixed rod 18 connects the top plate 1 and the adjusting plate 11, enabling synchronous lifting and lowering of the top plate 1 and the adjusting plate 11. During the lifting and lowering of the top plate 1, the guide rod 2 guides its movement. The support plate 3 limits the downward movement range of the top plate 1, preventing the manhole cover from being inserted too deeply. The adjusting plate 11 provides support and reinforcement for the top of the connecting piece 2 15. The drive structure installed inside the connecting piece 2 15 drives the connecting piece 2 15. The first connector 14 rotates on one side of the second connector 15, thereby changing the tilt angle of the gripper 12 and adjusting the gripping state of the gripper 12 on the manhole cover. The hydraulic cylinder 16 can adjust the working height of the pressing plate 19, thereby pressing the top of the manhole cover with the pressing plate 19 to improve the tightness of the connection between the manhole cover and the manhole seat during installation. At the same time, the motor 10 can provide power for the rotation of the threaded rod 13. The rotation of the threaded rod 13 drives the adjusting plate 11 to rise and fall along the frame 8, thereby changing the height of the manhole cover so that the bottom of the manhole cover can pass smoothly through the arc hole on the support plate 3 and then be inserted into the manhole seat.

[0025] Example 2: Figure 1 and Figure 2 As shown, in this embodiment, the support plate 3 has an arc-shaped hole at the top, the bottom of the support plate 3 is fixedly connected to the frame 8, an electric push rod 7 is fixedly connected to one side of the frame 8, a detection frame 5 is fixedly connected to one end of the electric push rod 7, one side of the detection frame 5 is slidably connected to the frame 8, an infrared ranging sensor 6 is fixedly connected to one side of the detection frame 5, a slider is fixedly connected to the bottom of the frame 8, a guide rail 4 is slidably connected to the bottom of the slider, and a pin is inserted between the top of the guide rail 4 and the slider.

[0026] The arc-shaped hole reduces the obstruction of the support plate 3 when the manhole cover moves down. The frame 8 provides support for the bottom of the support plate 3, thereby improving the stability of the support plate 3 during use. The frame 8 can also support and reinforce one end of the electric push rod 7, and guide the movement of the detection frame 5, improving the stability of the detection frame 5 during movement. The infrared distance sensor 6 can detect the distance between the manhole base and the detection frame 5, thereby assisting in the calibration of the entire device's placement position. The guide rail 4 guides the movement of the frame 8, making it easier to move the manhole cover directly above the manhole base and reducing positional deviations during manhole cover installation.

[0027] The usage and working principle of this device are as follows: In actual use, a caster wheel is installed on one side of the guide rail 4. The entire device is moved to the vicinity of the well base using the caster wheel, so that the guide rail 4 is positioned on both sides of the well base. At this time, the electric push rod 7 drives the detection frame 5 to move along the frame 8 until the infrared distance sensor 6 is located on one of the quarter points of the well base. The infrared distance sensor 6 is used to detect the distance between the well base and the two infrared distance sensors 6. If the distances are the same, or the error is within the standard range, the current installation position is correct. The clamp 12 is inserted into the through hole on the well cover to clamp the well cover. The pin between the guide rail 4 and the slider is removed, and the frame 8 is moved along the guide rail 4. The manhole cover held by the gripper 12 moves to the top of the manhole seat. At this time, the motor 10 drives the threaded rod 13 to rotate, the adjusting plate 11 drives the top plate 1 to move down, and the gripper 12 drives the manhole cover to move down, passing through the arc-shaped hole on the support plate 3. Then, the bottom of the manhole cover is inserted into the inner cavity of the manhole seat. Then, the driving structure installed inside the connector 2 15 drives the gripper 12 and the connector 1 14 to rotate on one side of the connector 2 15, so that the inner wall of the gripper 12 separates from the manhole cover. Then, the threaded rod 13 drives the adjusting plate 11 to move up. At this time, the gripper 12 separates from the manhole cover. The hydraulic cylinder 16 drives the pressing plate 19 to move down and press the manhole cover. Then, the pressing plate 19 is reset, and the installation of the manhole cover is completed.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
