Description

Technical Field

[0001] This utility model relates to the field of manhole cover installation technology, specifically a leveling device for installing road manhole covers. Background Technology

[0002] Uneven manhole covers (protruding or sunken) can cause severe vibrations when vehicles pass over them, easily leading to chassis scraping, tire damage, and even loss of vehicle control, especially posing a greater threat to two-wheeled vehicles such as motorcycles and bicycles. Furthermore, tilted manhole covers, subjected to uneven pressure over time, are prone to cracking and displacement, increasing maintenance costs. Additionally, the shaking of the manhole cover and rainwater seeping into surrounding gaps can accelerate roadbed erosion, leading to road surface collapse or cracks.

[0003] Regarding the issue of leveling manhole covers during installation, several patent applications exist, such as CN222541534U, a road manhole cover leveling and installation auxiliary device, and CN222500352U, a height-adjustable manhole cover leveling pad, which improves upon the leveling bolt leveling pad. However, multiple pads are required in use, necessitating frequent adjustments, and the flatness depends on on-site workers using a spirit level. Patent CN223088493U, a road manhole cover installation and leveling device, discloses a measuring structure but does not cover the specific installation process. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In actual installation, manhole covers are generally installed on concrete washers, which are placed on the outer wall of the manhole. The flatness of the concrete washers (compared to the levelness of the road surface) directly affects the flatness of the manhole cover. (See attached image.) Figure 1-4 As shown, the leveling device for installing road manhole covers involved in this utility model includes a leveling bracket 1 and a washer clamping assembly 2.

[0020] The leveling bracket 1 includes a structural frame 11 and ball feet 12, as shown in the attached diagram. Figure 1 As shown, the structural frame 11 is welded from metal square tubes. In this application, a three-way support structure is adopted, with a central equilateral triangle welded from metal square tubes. Three support rods 111 extend outward from the three corners of the equilateral triangle, and ball feet 12 are provided at the ends of the support rods 111.

[0021] The ball foot 12 includes a metal ball 121 and a screw 122. The bottom of the screw 122 is connected to the center of the metal ball 121, and the upper part mates with a threaded hole provided at the end of the support rod 111. Specifically, a through hole is provided at the end of the support rod 111, and nuts are welded to the upper and lower ends of the through hole. An adjusting nut is also welded to the lower part of the screw 121. The relative distance between the metal ball 121 and the support rod 111 can be easily adjusted by adjusting the adjusting nut.

[0022] When in use, place the device on the road surface in the manhole cover installation area, and adjust the screw 122 to make the structural frame 11 parallel to the road surface. In the specific adjustment process, a spirit level can be used to assist in leveling, or the leveling can be achieved by measuring the distance between the end of each support rod and the road surface.

[0023] The washer clamping assembly 2 is located in the central area of ​​the structural frame 11.

[0024] The washer clamping assembly 2 includes an adjusting shaft 21, a base plate 22, and several clamping units 23.

A screw section is provided in the middle of the adjusting shaft 21, and the screw section passes through the nuts at the upper and lower ends of the structural frame 11. An adjusting handle 211 is provided on the upper part of the adjusting shaft 21.

[0026] A base plate 22 is provided at the lower part of the adjusting shaft 21. To ensure the base plate is securely fixed, the base plate 22 is connected to the adjusting shaft 21 through reinforcing ribs 221. To reduce the weight of the base plate, an array of weight-reducing through holes 222 are provided on the base plate 22.

[0027] The clamping unit 23 comprises three units arranged in a circular array on the base plate, including a clamping plate 231, an adjusting screw 232, a front support plate 233, and a rear fixing plate 234. The front support plate 233 and the rear fixing plate 234 are fixed to the base plate 22 and arranged along the same radius of the base plate 22. Through holes are provided on the front support plate 233 and the rear fixing plate 234, through which the adjusting screw 232 passes. Fastening nuts 235 are provided on the adjusting screws 232 on both sides of the rear fixing plate 234. A clamping plate 231 is provided at the front of the adjusting screw 232, and the clamping plate 231 is arranged perpendicular to the base plate 22 or hinged to the end of the adjusting screw.

[0028] The concrete washer can be clamped by adjusting the distance between the clamping plate 231 and the adjusting shaft 21.

[0029] Furthermore, a limiting protrusion 2311 is provided at the lower part of the clamping plate 231 to provide a certain support for the concrete washer at the lower part.
