Description

Technical Field

[0001] This application relates to the technical field of construction engineering, and particularly relates to a multi-directional leveling frame for installing a positioning manhole cover. Background Art

[0002] With the continuous development of the extensive road network, inspection wells are widely distributed on urban roads for the maintenance of power supply, water supply, drainage, sewage disposal, communication, cable TV, gas pipelines, street lamp lines, etc. of urban underground infrastructure. Generally, inspection wells are set at pipe intersections, turning points, where pipe diameters or slopes change, and at regular intervals on straight pipe sections, which are convenient for regular inspection of ancillary structures.

[0003] With the extensive distribution of inspection wells, most inspection manhole covers are sunken or protruding from the road surface. The manhole covers that are uneven with the road surface generate a bumpy feeling and noise when vehicles pass by, and become loose in the later stage, increasing the bumpy feeling and noise of the vehicles, and the overall connection aesthetics is relatively poor.

[0004] The occurrence of the uneven manhole cover phenomenon is caused by the inherent slope of the road itself and unreasonable installation. The installation and construction of the inspection well ring and manhole cover are adjusted by manual towing ropes or elevation measurements. The current use of brackets has got rid of the constraints of cumbersome construction, poor accuracy, and difficult control. However, the existing manhole cover adjustment and positioning principle uses tools such as leveling bars, plumb bobs, and inspection rulers for multiple adjustments of the level, improving the horizontal accuracy, but there is a certain degree of cumbersome nature, and the overall movement of the bracket is still required at a certain micro-distance, without the adjustment function in both horizontal and vertical directions, and it cannot specifically adjust the inclination angle when the road is inclined.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to make the purpose, technical solutions and advantages of the present disclosure clearer and more understandable, the following further describes the present disclosure in detail with reference to specific embodiments and the accompanying drawings.

[0034] To facilitate the understanding of the multi-directional leveling frame for installing a positioning manhole cover provided in the embodiments of the present application, its application scenario will be described first. With the large distribution of inspection wells, most inspection manhole covers are sunken or protruding from the road surface. The manhole covers that are uneven with the road surface generate a bumpy feeling and noise when vehicles pass by, and become loose in the later stage, increasing the bumpy feeling and noise of the vehicles, and the overall connection aesthetics is poor.

[0035] The occurrence of the uneven manhole cover phenomenon is caused by the inherent slope of the road itself and unreasonable installation. The installation and construction of the inspection well ring and manhole cover are adjusted by manual towing ropes or elevation measurements. The current use of brackets has got rid of the constraints of cumbersome construction, poor accuracy and difficult control. However, the existing manhole cover adjustment and positioning principle uses tools such as leveling bars, plumb bobs, and inspection rulers for multiple adjustments of the levelness, which improves the horizontal accuracy, but there is a certain degree of cumbersome nature, and the overall movement of the bracket is still required at a certain micro distance. It does not have the adjustment function in both the horizontal and vertical directions and cannot target the inclination adjustment when the road is inclined. In view of this, the present application provides a multi-directional leveling frame for installing a positioning manhole cover, with a simple overall structure and providing multi-directional adjustment, making the manhole cover flush with the road surface, increasing the aesthetics, reducing noise and the bumpy feeling.

[0036] Reference Figure 1, the multi-directional leveling frame for installing a positioning manhole cover provided by the embodiment of the present application includes: a support frame group clamped on the inner wall of the wellbore of the inspection well, and a leveling frame group connected to the top of the support frame group; the support frame group in the present application is used to provide positioning in the vertical direction, and the leveling frame group is used to provide positioning in the horizontal direction or the inclination direction, so as to accurately position the cushion thickness of the well ring installation, make the manhole cover flush with the road surface after installation, and reduce the occurrence of unevenness. It is convenient to carry and assemble as a whole, has high material utilization rate, is low-carbon and efficient in use, is not affected by the environment, and is easy to operate. Compared with the traditional bracket that adjusts through screws at a micro distance, the height can be adjusted without moving the whole bracket to control the flatness.

[0037] Specifically, when positioning the support frame group on the inner wall of the wellbore to provide positioning in the vertical direction, the support frame group includes: a plurality of support legs 1 and a reinforcing rod group connected between the plurality of support legs 1, and a jackscrew assembly 2 for pressing against the inner wall of the wellbore of the inspection well is assembled on each support leg 1; referring to Figure 3 As shown in, the jackscrew assemblies 2 are assembled back to back on any two relatively arranged support legs 1. Positioned on the inner wall of the wellbore through the jackscrew assembly 2 to provide support positioning in the vertical direction. In a specific embodiment of the present application, four support legs 1 are provided, and the four support legs 1 are distributed in pairs opposite to each other, so as to achieve four-directional positioning on the inner wall of the wellbore and realize stable support.

[0038] At the same time, in order to strengthen the strength between the plurality of support legs 1, the provided reinforcing rod group can ensure stable connectivity and is not easily deformed. Specifically, the reinforcing rod group includes: a lower reinforcing rod 7 connected between the plurality of support legs 1, and an upper reinforcing rod 3 connected between the tops of the plurality of support legs 1; the lower reinforcing rod is used to connect between the plurality of support legs 1 to increase the strength, and the upper reinforcing rod 3 is used to strengthen the strength and can preferably connect the leveling frame group.

[0039] Combined with Figure 2 As shown in, the leveling frame group includes a balance ring 8; reinforcing bars 10 are distributed in a cross shape inside the balance ring 8. Improve the connection strength of the balance ring 8. An inclination detection component 6 is assembled at the center of the balance ring 8, and the inclination detection component 6 is a gradient meter or a digital display inclinometer; the inclination detection component 6 is assembled at the cross intersection of the reinforcing bars 10. By displaying the levelness or inclination angle, the accuracy of the well ring installation is ensured. After the accuracy of the well ring installation is positioned, the manhole cover can be flush with the road surface and have the same inclination after being buckled.

[0040] Refer to together Figure 1 and Figure 4 As shown in, the balance ring 8 is connected to the reinforcing rod group through a plurality of positioning adjustment screws 4, and the balance ring 8 is connected to the reinforcing rod group as an axial end through at least one axial end adjustment screw 9. Specifically, the plurality of positioning adjustment screws 4 and the axial end adjustment screw 9 are both rotatably connected to the upper reinforcing rod 3.

[0041] Moreover, when the balance ring 8 is used as an axial end connecting and reinforcing rod group through at least one axial end adjusting screw 9, the installation inclination position of the manhole cover of the inspection well is positioned by the balance ring 8 after the plurality of positioning adjusting screws 4 are correspondingly adjusted. The fine-tuning effect is achieved, and the matching performance is higher. The fine-tuning in this application is 5 mm to 20 mm. Since the area of the manhole cover is small and the existing inclination angle is small, the matching of the road inclination effect can be achieved.

[0042] When the number of the axial end adjusting screws 9 is one, the number of the plurality of positioning adjusting screws 4 is at least three. Adjustments in multiple directions are realized to ensure high adjustment convenience. Specifically, each positioning adjusting screw 4 includes: a screw member threadedly connected to the balance ring 8; wherein, the screw member is rotatably connected to the upper reinforcing rod 3. The overall structure is simple and the adjustment method is convenient. A threaded hole adapted to the screw member is formed in the balance ring 8, and the upper reinforcing rod 3 is rotatably connected to the screw member through a bearing 5. The threaded adjustment method is adopted to improve the adjustment accuracy. The axial end adjusting screw 9 includes: a threaded rod and a fine adjustment rod group; wherein, the threaded rod is threadedly connected to the balance ring 8; a semi-circular limiting groove 93 is formed at the bottom of the threaded rod, and a rotating ball head 91 adapted to the semi-circular limiting groove 93 is assembled at the first end of the fine adjustment rod group, and the rotating ball head 91 is connected to the upper reinforcing rod 3 through a connecting rod 92. The axial end adjusting screw 9 serves as an adjusting axial end, rotates in multiple directions when the plurality of point adjusting screws are adjusted, adjusts the inclination angle of the balance ring 8, so as to be adapted to the inclination of the road surface, and the overall adjustment method is simple and convenient.

[0043] As can be seen from the above structure, after the support frame group is positioned in a direction perpendicular to the wellbore, the height of the entire balance ring 8 is initially in a horizontal state and monitored by the inclination detection assembly 6. Under the condition of a flat road surface, the laying thickness of the cushion under the manhole ring is obtained, so as to achieve the precise installation of the manhole ring, and be consistent with the flat road surface after the manhole cover is installed later. When the road is in an inclined state, the horizontal height of the balance ring 8 is initially flush with the low point of the road surface or slightly higher than the low point of the road surface, and the axial end adjusting screw 9 is in the same position as the low point of the road surface, so as to correspondingly adjust the height of the plurality of positioning adjusting screws 4. The semi-circular limiting groove 93 rotates in different directions along the rotating ball head 91 to achieve a fine-tuning effect, so that the balance ring 8 is in the same inclination angle as the road surface. Subsequently, according to the inclination angle value, the balance ring 8 is integrally adjusted to be flush with the road surface, and different thicknesses of the cushion under the manhole ring are obtained, and it is flush with the road after the manhole cover is installed later. Of course, it should be understood that in other embodiments of the present application, rotating ball heads 91 can be provided at both ends of the connecting rod 92, so as to expand the adjustment range.

[0044] In this application, the support frame group provides vertical adjustment and positioning, and the leveling frame group provides horizontal adjustment and positioning. When the road is in an inclined state, the shaft end adjusting screw 9 serves as the shaft end, and multiple positioning adjusting screws 4 are used to finely adjust and match the road inclination, so that the manhole cover is installed accurately. After the manhole cover is installed, the overall appearance is beautiful and there is no unevenness with the road surface.
