Bridge rubber support degree of coming to nothing measuring device

Technical Field

The utility model relates to a bridge detects technical field, in particular to bridge rubber support degree of coming to nothing measuring device.

Background

The bearing is an important structural member form in the bridge. In the bridge structure, the support plays a role in transferring upper load and providing a deformation condition of the main beam. In recent years, the rubber support has become the most common bridge support shape in highway bridges due to the advantages of simple structure, low cost, convenient construction, less maintenance workload and the like. However, the site where the support is empty is often caused by reasons such as poor construction quality control. The support is empty, so that the stress condition of the upper structure of the bridge is directly changed, the counter force of the support is suddenly changed, and the safety of the bridge structure can be threatened by a person with serious conditions.

In the current artificial bridge inspection, the rubber plate type support is mostly subjected to visual inspection or the size and the clearance length of the support are measured by a steel tape and a ruler, and the contact line between the support and a structure is difficult to position, so that a larger error exists when the rubber plate type support, particularly the circular rubber plate type support is measured by the circular steel tape and the ruler.

In order to solve the above problems, in the prior art, a portable bridge support clearance inspection device disclosed in CN215832611U has a technical scheme that a center line of a positioning shaft is overlapped with contact points of a support and a structure, so that the clearance length is read. However, in the technical scheme, the contact line between the support and the structure is not easy to visually judge and position, so that the error of reading and measuring is large due to the judgment by naked eyes alone.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a bridge rubber support degree of coming to nothing measuring device, location support and structure contact wire that can be accurate to more accurate reading size data that comes to nothing improves the detection precision.

In order to solve the technical problem, the technical scheme of the utility model is that:

a bridge rubber support gap degree measuring device comprises a main scale, a first caliper and a second caliper; one end of the main scale is hinged with the first caliper, and the other side of the main scale is in sliding connection with one end of the second caliper; a first sub caliper is vertically connected in a sliding manner along the length direction of the first caliper; a second sub caliper is vertically connected in a sliding manner along the length direction of the second caliper; the first caliper and the second caliper can both move in the width direction of the first caliper and the second caliper respectively.

Further, first minute slide caliper rule and second minute slide caliper rule are equallyd divide and are connected with first slide caliper rule and second slide caliper rule through the mode of magnetism.

Furthermore, main scale, first slide caliper rule and second slide caliper rule all adopt square pipe, and all are equipped with the range at the surface outward.

Furthermore, the upper surfaces and the lower surfaces of the first caliper and the second caliper are correspondingly provided with through grooves; and a fastening limiting part is arranged corresponding to the through groove.

Further, the sum of the measuring ranges of the first sub caliper and the second sub caliper is less than or equal to the measuring range of the main scale.

The utility model has the advantages that:

1. the utility model discloses a first slide caliper rule and second slide caliper rule are set up on first slide caliper rule and second slide caliper rule, and first slide caliper rule and second slide caliper rule can also stretch into along main scale length direction and measure; set up the location axle on first slide caliper rule and second slide caliper rule among the prior art, then with the mode of visual observation support and structure contact point, the utility model discloses a directly stretch into, then read the reading, therefore more accurate.

2. The measurement of the local void is achieved by directly extending into and then reading the reading.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, a bridge rubber bearing gap measuring device includes a main scale 1, a first caliper 2 and a second caliper 3; one end part of the main scale 1 is hinged with the first caliper 2, and the other side of the main scale 1 is in sliding connection with one end part of the second caliper 3; a first caliper 4 is vertically connected in a sliding manner along the length direction of the first caliper 2; a second sub caliper 5 is vertically connected in a sliding manner along the length direction of the second caliper 3; the first and

second caliper

4, 5 are each movable in the width direction of the first and

second calipers

2, 3, respectively.
