Description

H-shaped steel strut correcting tool for contact network without track section

Technical Field

The utility model relates to a neat instrument specifically relates to a neat instrument of H shaped steel pillar.

Background

The H-shaped steel support of a contact network in a trackless section is required to be adjusted frequently in a construction site, the type of the H-shaped steel support is (GZ 240), the general method is that after the support is assembled, a truck crane is used for adjusting the gradient and the limitation of the support, once a crane is withdrawn, the gradient of the steel support needs to be finely adjusted, the operation difficulty is relatively large, a traditional whole bar device needs to be fixed on a steel rail for operation, the trackless section is limited by the operation terrain and cannot use the traditional whole bar device, a crowbar is generally used for prying a flange plate of a steel support base, the use of the crowbar often damages the foundation surface of the H-shaped steel support to cause the phenomena of corner lacking, pitted surface, pits and the like, the steel support base is pried by the crowbar, and the gradient operation precision of the steel support is not.

Disclosure of Invention

In order to solve the problems, the utility model provides a straightening tool for H-shaped steel struts of a contact net of a non-track section, which comprises a hoop, two piston rods, two ground foot metal plates and a fixed probe, wherein the hoop is two rectangular channel steels connected by bolts, a metal bolt is connected to the outer side of the middle position of the channel steel in a shaft mode, the piston rod is a metal rod with internal threads at two ends, the central position of the foundation metal plate is connected with a metal bolt through a shaft, the internal threads at the two ends of the piston rod are respectively matched with the bolt connected with the hoop channel steel shaft and the bolt connected with the foundation metal plate through the shaft, the two bolts connected with the anchor ear channel steel and the anchor foot metal plate are respectively arranged in reverse directions, so that when the piston rod is rotated in the same direction, the two bolts enter the piston rod at the same time or are screwed out of the piston rod at the same time, and the foundation metal plate is provided with a round hole for the fixed probe to pass through.

Furthermore, the round holes which are arranged on the ground foot metal plates and used for the fixed probes to pass through are at least two

Furthermore, handles fixedly connected with the two piston rods are arranged on the two piston rods.

Furthermore, the handle is designed in a split mode and consists of a fixed part fixedly connected to the piston rod and a detachable columnar handle.

The utility model provides a because the unable condition of using large-scale neat equipment and harm pillar chassis that the place problem caused, have advantages such as convenient, safety, strong adaptability.

Note: the schematic diagram only shows the structure, and the specific size ratio is not limited.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can smoothly implement the present invention.

As shown in fig. 1, a trackless section contact net H-shaped steel pillar straightening tool comprises an anchor ear 1, two piston rods 2, two foundation metal plates 3 and a fixed probe 4, wherein the anchor ear 1 is two rectangular channel steels 5 connected by bolts, a metal bolt 6 is connected to the outer side of the middle position of the channel steel through a shaft, the piston rod 2 is a metal rod with internal threads at two ends, a metal bolt 7 is connected to the center position of the foundation metal plate 3 through a shaft, the internal threads at two ends of the piston rod are respectively matched with the bolt 6 connected with the anchor ear channel steel shaft and the bolt 7 connected with the foundation metal plate shaft, the rectangular steel 5 of the hoop groove and the two bolts 6 and 7 connected with the foundation metal plates 3 are respectively arranged in a reverse direction, so that when the piston rod 2 is rotated in the same direction, the two bolts 6 and 7 simultaneously enter or simultaneously screw out of the piston rod 2, and the ground margin metal plate 3 is provided with a round hole 8 for the fixed probe to pass through.

In order to increase firmness, the round holes which are arranged on the foundation metal plate 3 and used for the fixed probes to pass through are at least two

For convenient operation, the two piston rods are provided with handles 9 fixedly connected with the piston rods.

For the convenience of installation, the handle text 9 is designed as a split body and consists of a fixed part 10 fixedly connected to the piston rod and a detachable column-shaped handle grip 11.

During specific operation, the anchor ear 1 is fixed at the corresponding height of the H-shaped steel upright column to be aligned, and the distance between the anchor ear 1 and the ground is about 1.5 meters generally. Carry out furthest's connection with bolt 6 on the staple bolt 1 and the lower margin metal sheet 3 on with piston rod 2 respectively and finish, namely will the whole screw in internal threads at two ends of piston rod 2 of two bolts are aerial, will the handle of handle is installed on the fixed part that corresponds, because two bolts are opposite settings, so only need toward one direction rotatory piston rod 2, can accomplish above operation. Then adjust lower margin metal sheet 3 to suitable position (guarantee about that piston rod 2 and ground are 45 degrees angles), drive fixed probe 4 into ground through the round hole 8 on the lower margin metal sheet. And then selecting the piston rod 2 to be operated according to the direction of the H-shaped steel upright post to be straightened, and rotating the piston rod to screw out the bolts at the two ends until the H-shaped steel upright post is straightened. The H-shaped steel upright column base is fixed, the straightening is completed, and the operation can be completed by detaching the tool.
