Description

Stability device with adjustable height of manhole

The invention relates to a stabilizing device capable of adjusting the height of a manhole, in particular to a height adjusting device that can adjust the height of a manhole cover to simplify road maintenance works and reduce maintenance costs.

Under the influence of long-term vehicle loading on general roads, due to the difference in the bearing capacity of the original road structure and the backfill area, the difference in subsidence between the two causes the shear force to deform the pavement and cause the difference in height.

On the other hand, public works are often criticized by others, because there are quite a lot of authority units responsible for underground pipelines, and there is no coordinated and coordinated construction agency. Each authority unit has strong standardism and contracting out layers. Digging up is often commonplace. It can be understood that the road repeatedly digs repeatedly, and the construction is frequently repaired. The amount of subsidence caused by the vehicle load originally caused by the vehicle load will not be the same as the subsidence in the backfill area, resulting in uneven pavement or high and low pits. .

For the most common situations where the existing road paving is uneven, such as the high and low drop between the manhole cover and the road surface, the reasons include the insufficient soil bearing capacity of the roadbed, and the manhole hole subsidence causes the hole cover to be lower than the road surface. Another situation is that around the manhole cover The subsidence of the road surface will cause the manhole cover to protrude from the road surface and form an uneven drop, which will affect the comfort of people and vehicles, and even cause car accidents and accidents.

This kind of manhole cover is higher than or lower than the road surface. It is common in Taiwan's roads. The traditional maintenance method is to remove or dig to adjust the height difference between the road surface and the manhole cover, whether it is planed or excavated. The methods are all large-scale engineering, which consumes manpower, man-hours and costs. Even after the road surface has been re-paved or the height of the excavated box culvert has been adjusted, it will repeat the same mistakes after a period of vehicle rolling. At present, the traditional construction methods cannot fully meet the requirements of road durability.

It is known that many related documents about "manhole structure" have been proposed, such as Taiwan Invention Patent 571015 and Taiwan New Patent M373936.

The main object of the present invention is to provide a stabilizing device capable of adjusting the height of a manhole. The height of the manhole cover can be adjusted by a height adjusting device, so as to simplify road maintenance works and reduce maintenance costs.

In order to achieve the above object and other objects, the present invention provides a stabilizing device with adjustable height of a human hand hole, which mainly includes: a box-shaped structure and a height adjusting device. The box-shaped structure is composed of a peripheral wall and a base plate. Box space.

Wherein, the height adjusting device includes a lower base, which is combined with a rectangular frame above the box-shaped structure. The lower base corresponds to the peripheral side wall and includes four facing chute slots. Corners, and each screw seat has internal threads.

Four screws, the bottom ends of which are screwed into the four screw seats, and the upper end of each screw includes a radial shaft hole, which is passed through one end of the rod The screw is arranged in the shaft hole to force the screw into or out of the screw seat through the other end.

An upper base has a rectangular frame corresponding to the upper base. The upper base includes four facing frames corresponding to the four facing chute. Each frame is provided with at least one or two axes. A pole seat; and four sockets positioned on the four corners of the upper base, and the four sockets are received at the top ends of the four screws.

A plurality of sliders, each pair of which is a pair, is slidably corresponding to each of the sliding grooves embedded in the lower base. A plurality of shaft members, one end of each shaft member is pivotally connected to each slider via a shaft pin, and the other end is pivotally connected to a corresponding shaft seat of the upper base via a shaft pin. When the upper base is raised, the distance between each pair of sliders is relatively closer.

Preferably, a pair of telescopic baffles are interposed between the lower base and the upper base to block dirt and sand from the roadbed from entering the box structure. The telescopic baffle includes a lower baffle and an upper baffle. The lower baffle is detachably fixed to the outer side of the periphery of the lower base. The upper baffle is detachably fixed to the outer side of the periphery of the upper base. The baffle may be staggered from the lower baffle as the upper base rises.

In addition, it includes a human hand hole cover, which includes a hollow rectangular frame and an upper cover embedded in the rectangular frame. The rectangular frame is fixed above the upper base and is flush with the ground.

According to this, when the hole subsidence of the human hand causes the hole cover to be lower than the road surface, or, whether it is, or the road surface subsidence around the human hand hole cover causes the human hand hole cover to protrude from the road surface, the unevenness of the road surface is formed. Small excavations around the cover, the height of the manhole cover can be adjusted by rotating a plurality of screws, which can simplify road maintenance works and reduce maintenance costs.

By rotating the screw 23, the screw 23 can be screwed into or withdrawn from each screw seat 212.

Furthermore, the box-shaped structure 1 of the conventional human hand hole includes many different specifications and sizes to choose from according to different requirements. For the example in the figure, the cross-section of the box-shaped structure 1 is rectangular, and Including a long side direction and a short side direction, of course, it is not limited to this.

The upper base 25 has a rectangular frame and is disposed above the lower base 21. The upper base 25 includes two long grooves 211 corresponding to the two long sides of the lower base 21 and two short frames corresponding to the two short sides 211 of the lower base 21. Wherein, a pair of shaft bases 251 are provided on each of the long frames, at least one shaft base 251 is provided on each of the short frames, and four bearing bases 252 are positioned on the four bases 25. Corners, and the four sockets 251 are received at the top ends of the four screws 23.

In addition, the plurality of sliders 27 are slidably embedded in the four facing sliding grooves 211 of the lower base 21; preferably, the sliding grooves 211 in the short side direction and the sliding grooves in the long side direction In 211, a pair of sliders 27 are provided. The plurality of shaft members 253 are respectively connected between the shaft holders 251 and the sliders 27, as shown in FIG. 4, including a pair of shaft members 253, one end of each of the shaft members 253, Each is pivotally connected to a slider 27 of the short-side sliding slot 211 via a shaft pin; the other end of each shaft member 253 is pivotally connected to a shaft seat 251 of the short frame of the upper base 25 through a shaft pin. The side.

As shown in FIG. 5, a pair of shaft members 253 are included, and one end of each shaft member 253 is pivotally connected to the long side via a shaft pin.
