Description

Technical Field

[0001] The utility model relates to the technical field of road manhole cover installation, in particular to an auxiliary device for road manhole cover installation, specifically a road manhole cover installation leveling device. Background Technique

[0002] With the acceleration of the urbanization construction speed, the scale of urban construction is also getting larger and larger. During the urbanization construction process, the requirements for project quality are becoming increasingly strict. Among them, road construction is the lifeblood of the city. There are many manhole covers in urban roads, and the installation quality of manhole covers directly affects the comfort level of the road during use. Generally, the manhole cover needs to be installed in place in advance before the upper layer is paved. The operator needs to combine the thickness of the upper layer and the elevation at the manhole cover to level the installation of the manhole cover. The traditional methods for leveling the installation of road manhole covers generally use methods such as pulling a wire rope or measuring elevation. However, these methods are not only time-consuming and laborious, but also have poor leveling accuracy. After installation, there are often large height differences at the connection between the upper layer and the manhole cover, warping of the manhole cover, and poor visual quality, which in turn leads to cracking of the surface layer around the manhole cover, loud noise of the manhole cover, poor driving comfort, and even traffic accidents. Summary of the Invention

[0003] In order to solve the problems that the traditional method for leveling the installation of road manhole covers is time-consuming and laborious and has poor leveling accuracy, the utility model provides a new road manhole cover installation leveling device.

[0004] The utility model is realized by adopting the following technical scheme:

[0005] A road manhole cover installation leveling device includes a cross bar composed of four rods fixedly connected. Support legs are provided at the free ends of the four rods of the cross bar. Limit sleeves are fixed on the sides of the four rods of the cross bar. A positioning ruler rod with scale lines is slidably installed up and down in each limit sleeve. A limit threaded hole is opened on the peripheral wall of each limit sleeve, and a limit set screw is adapted to each limit threaded hole. A chassis is fixed at the bottom end of each positioning ruler rod. A leveling sleeve is also slidably sleeved up and down outside each positioning ruler rod. The leveling sleeve is located between the limit sleeve and the chassis. A leveling threaded hole is opened on the peripheral wall of each leveling sleeve, and a leveling set screw is adapted to each leveling threaded hole. A leveling needle with its free end facing the center of the cross bar is also fixed on the outer peripheral surface of each leveling sleeve.

[0006] Usage steps: 1) Place the device at the pre-installed road manhole cover so that the center of the cross bar of the device is basically aligned with the center line of the pre-installed manhole cover frame; 2) Loosen the limit set screw so that the positioning ruler rod falls freely and the chassis naturally contacts the lower layer of the road; 3) Tighten the limit set screw to lock the positioning ruler rod; 4) Calculate the height of the upper edge of the manhole cover frame according to the thickness of the upper layer. The height of the upper edge of the manhole cover frame is the control height of the leveling needle; 5) Loosen the leveling set screw and adjust the corresponding leveling needle to the calculated control height; 6) Based on the horizontal height indicated by the leveling needle, adjust the manhole cover frame, position it in place and fix it.

[0007] Further, a plurality of limit holes with their axes vertically arranged are provided on each of the four rods of the cross bar. A limit ring is slidably sleeved outside each of the four rods of the cross bar along the length direction of the rod. A fixing hole with its axis vertically arranged is opened on the limit ring. A limit pin is inserted into the fixing hole and the limit hole to fix the position of the limit ring. The limit sleeve is fixed to the side surface of the limit ring. During use, adjust the position of the limit sleeve on the four rods according to the size of the manhole cover, so that the four limit sleeves are arranged adjacent to the manhole cover frame, and at the same time, the distances from the four limit sleeves to the center of the cross bar are the same, which is convenient for the operator to level and improves the leveling accuracy.

[0008] Further, the four support legs are all support legs with adjustable heights, which are convenient for adapting to various working environments.

[0009] Further, the four support legs are respectively inserted up and down through the free ends of the four rods of the cross bar. A plurality of telescopic holes are evenly distributed along the height direction on each of the four support legs. Horizontal support holes adapted to the telescopic holes are provided at the free ends of the four rods of the cross bar. A positioning pin is inserted into the horizontal support hole and the telescopic hole to adjust the height of the corresponding support leg.

[0010] Further, universal wheels with brake brakes are provided at the bottoms of the four support legs, which are convenient for moving and locking the brakes of the universal wheels when entering the measurement state.

[0011] Further, the four rods of the cross bar are all foldable rods, which are convenient for carrying.

[0012] The beneficial effects produced by the present utility model are as follows: 1) The road manhole cover installation leveling device described in the present utility model ingeniously uses a cross bar to construct a precise leveling platform for the manhole cover, and uses the ingenious concept of the cross bar to extend the elevation in both the longitudinal and transverse slopes of the road, providing a convenient and accurate measurement basis for the installation and leveling of the manhole cover; 2) A simple and accurate manhole cover installation elevation positioning system is formed by using a positioning ruler rod and a leveling needle; 3) The structure of the road manhole cover installation leveling device described in the utility model is simple, the measurement is accurate, it is convenient to manufacture and can be reused, and the operation is convenient and labor-saving.
