Problems solved by technology

The main thing, this simple replacement is bound to increase the production volume of different specifications of the component, increasing unnecessary costs
In addition, because the adjustment bracket is only in contact with the lower fine-tuning screw, but not fastened, when the fine-tuning goes up, it can be adjusted by relying on the thrust o

Embodiment Construction

[0015] The principle of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0016] Refer to the attached figure 1 and 2 The height-adjustable road manhole cover in this specific embodiment includes a manhole cover 2, an upper wellhead 1 and a lower wellhead 9 cooperating with the manhole cover, and two lifting devices 7 and two auxiliary supports 10 connecting the upper and lower wellheads. The lifting device and the auxiliary support are evenly distributed in the circumferential direction on the upper bottom surface of the lower wellhead at a distance from each other, and the lower screw rods of the two are connected with the nuts of the lower wellhead; the auxiliary support is in contact with the lower bottom surface of the upper wellhead, and the lifting device is hinged to the upper wellhead lower part. The selection of the number of lifting devices and auxiliary supports should be consistent with the bearing area of ​...

Abstract

The invention discloses a road manhole cover with adjustable height, comprising a manhole cover, an upper manhole and a lower manhole which match with the manhole cover, at least two lifting devices and at least two auxiliary supports, which are connected with the upper manhole and the lower manhole. The lifting devices and the auxiliary supports are evenly distributed on the circumference of the upper underside of the lower manhole at intervals, and the screws at the lower parts of the lifting devices and the auxiliary supports are connected with the threads of the lower manhole; wherein the auxiliary supports contact with the lower underside of the upper manhole and the lifting devices are hinged at the lower part of the upper manhole. The road manhole cover is convenient to be adjusted in height, low in cost, stable in structure and adjustable in height.

Description

(1) Technical field [0001] The invention relates to a height-adjustable road manhole cover, which belongs to the technical field of road pavement wellhead facilities. Specifically, it relates to a road with an upper wellhead and a lower wellhead, and the height of the manhole cover can be adjusted by adjusting the distance between the upper and lower wellheads. manhole cover. (2) Background technology [0002] The structure of the manhole cover that is put into use now is basically composed of the manhole cover and the wellhead. However, due to this type of well structure, the positional relationship between the well cover and the wellhead is fixed, and the height of the well cover cannot be adjusted. Although road surface construction can basically guarantee its flatness now, road construction defects are inevitable, and sometimes the height difference between the upper surface of the manhole cover and the road surface will be relatively large. The existence of this heigh...
