Abstract
The utility model discloses a manhole cover for bridge overhauling. The manhole cover for bridge overhauling is arranged at the position, provided with a manhole, of a bottom plate of a bridge. The manhole cover for bridge overhauling comprises a base plate and a manhole cover body arranged on the base plate. The base plate is an annular base plate and is arranged surrounding the manhole and fixedly welded to the upper surface of the bottom plate of the bridge. The manhole cover body is movably connected with a hinge pin base through a hinge pin, and the hinge pin base is fixedly arranged beside the base plate. A handle is fixedly welded to the lower surface of the manhole cover, and the handle outward extends out of the manhole. The manhole cover for bridge overhauling is simple in structure. By arranging the manhole cover body inside the bridge structure to be movably connected with the hinge pin base through the hinge pin, when the bridge needs to be overhauled, a maintainer only needs to hold the handle and upward push the manhole cover body, then, the manhole cover body can be opened, the maintainer enters the bridge to conduct overhauling, and therefore time and labor are saved, the operation is safe and reliable, the possibility that dangers occur when the maintainer works high above the ground is greatly lowered, and personal safety of the maintainer is ensured.
Description
Technical field
The utility model relates to steel structure bridge technical field, more particularly, relates in particular to a kind of bridge maintenance by manhole cover.
Background technology
Bridge maintenance manhole cover is the common member for bridge maintenance, maintaining.As shown in Figure 1, existing design scheme is on bridge base plate 1, to offer the place of people's hole 11, adopts bolt 4 manhole cover 3 dead bolts to be connected on to the below of bridge base plate 1, and between manhole cover 3 and backing plate 2, lays rubber washer 5 to guarantee its sealing.Adopt this kind of mode that manhole cover is installed, under the impact of gravity, during dismounting manhole cover, need to apply the power making progress in case its degeneration to it, restriction due to factors such as locus, plant equipment is often lack scope for their abilities, therefore can only rely on manpower to support, effort so not only, but also increased the danger of work high above the ground.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of bridge maintenance by manhole cover, manhole cover is placed in to the inside of bridge construction, easy access personnel enter bridge inside and overhaul, time saving and energy saving, reduce the probability that work high above the ground is caused danger simultaneously.
For achieving the above object, bridge maintenance provided by the utility model by manhole cover, be installed on the position that offers people's hole on bridge base plate, comprise backing plate and be placed in the manhole cover above backing plate, described backing plate is annular backing plate, and it is around the setting of people's hole and be fixedly welded on the upper surface of bridge base plate, and described manhole cover is flexibly connected with the axis pin base that is fixedly arranged on backing plate side by bearing pin, soffit at manhole cover is welded and fixed jug, and described handle is protruding from people's hole.
The utility model is simple in structure, manhole cover is placed in to the inside of bridge construction, and be flexibly connected by bearing pin, when bridge need to overhaul, maintainer only need hold handle and upwards push away manhole cover, just manhole cover can be opened, enter bridge inside and overhaul, time saving and energy saving, safe and reliable, greatly reduce the probability that work high above the ground is caused danger, guaranteed maintainer's life safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
In figure: 1-bridge base plate; 11-people's hole; 2-backing plate; 3-manhole cover; 31-handle; 4-bolt; 5-rubber washer; 6-bearing pin; 7-axis pin base; 8-alignment pin; 9-dowel hole.
The specific embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Consult shown in Fig. 2, a kind of bridge maintenance provided by the utility model by manhole cover, be installed on the position that offers people's hole 11 on bridge base plate 1, comprise backing plate 2 and be placed in backing plate 2 manhole cover 3 above, described backing plate 2 is annular backing plate, it arranges and is fixedly welded on the upper surface of bridge base plate 1 around people's hole 11, described manhole cover 2 is flexibly connected with the axis pin base 7 that is fixedly arranged on backing plate 2 sides by bearing pin 6, between manhole cover 3 and backing plate 2, be provided with rubber washer 5, the sealing of installing in order to guarantor's port lid 3.
Described bridge base plate 1 is also welded with an alignment pin 8 at the periphery of people's hole 11, described alignment pin 8 and axis pin base 7 are on same axis, the corresponding dowel hole 9 matching with alignment pin 8 that offers on manhole cover 3 and backing plate 2, alignment pin 8 passes from two dowel holes 9 that overlap.
Soffit at manhole cover 3 is welded and fixed jug 31, and described handle 31 is protruding from people's hole 11.When bridge need to overhaul, maintainer only need hold handle 31 and upwards push away manhole cover 3, manhole cover 3 is rotated around bearing pin 6, just manhole cover 3 can be opened, enter bridge inside and overhaul, time saving and energy saving, safe and reliable, greatly reduce the probability that work high above the ground is caused danger, guaranteed maintainer's life safety.
