Description

Technical Field

[0001] The utility model relates to the technical field of railway engineering, and particularly relates to an adjustable leveling tensioner for railway anchor bolts detection. Background Art

[0002] In railway engineering, catenary poles, guy wire bases, etc. are all connected to the catenary foundation through anchor bolts embedded in the foundation. However, during the construction process, due to insufficient length, different forms, etc. of the embedded anchor bolts, the embedding of the anchor bolts does not meet the design requirements. Since the structure embedded in the concrete cannot be directly judged from the appearance, it is necessary to determine whether its bearing capacity meets the design requirements through the pulling method.

[0003] However, the commonly used hydraulic pullers at present generally adopt the method of directly installing on the base for pressurization. There are various situations for the catenary anchor bolt base: some bases are uneven, which will cause the tensioner to not be in tight contact with the base, resulting in inaccurate detection force values; some even have a directly designed inclined angle for the base, and there is a certain included angle between the catenary anchor bolt and the base, causing the anchor bolt to be bent laterally during the detection process. First, it affects the use of the catenary anchor bolt, and second, the detection force value is inaccurate. These above problems seriously affect the project quality and leave great potential safety hazards for the safe operation of the catenary in the future. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable leveling tensioner for railway anchor bolts detection to solve at least one of the above technical problems.

[0005] In the first aspect, an embodiment of the utility model provides an adjustable leveling tensioner for railway anchor bolts detection, including: a housing, an upper cover is arranged on the top of the housing, a piston is arranged inside the housing, and the railway anchor bolt to be detected is fixed inside the piston; wherein, a plurality of fixing ears are arranged on the outer side wall of the housing, and a horizontal adjusting column is arranged on each fixing ear, and the distance between the bottom end of the horizontal adjusting column and the fixing ear is adjustable.

[0006] Further, a level is arranged on the top of the upper cover.

[0007] Further, four of the fixing ears are arranged on the outer side wall of the housing in a circumferentially and uniformly distributed manner.

[0008] Further, the horizontal adjusting column includes a screw rod, and a screw hole matching the screw rod is arranged on the fixing ear.

[0009] Further, a sealing cover is arranged at the bottom of the housing.

[0010] Further, the sealing cover and the bottom of the housing are fixedly connected by bolts.

[0011] The utility model provides an adjustable leveling stretcher for railway floor anchor bolts. By setting fixing ears and horizontal adjusting columns on the outer side wall of the housing, when the foundation where the railway floor anchor bolts are located is uneven, the stretcher can be adjusted to be balanced by adjusting the horizontal adjusting columns, ensuring the accuracy of the detection force value during the detection process and alleviating the problem that the detection force value of the existing hydraulic puller is inaccurate under the condition of an uneven base.
