Description

Technical Field

[0001] This utility model relates to the field of engineering surveying, specifically to a rail clamping device for obtaining the center point of a track in a sliding track measurement. Background Technology

[0002] Shipyard slipways are common hydraulic structures used in shipbuilding and repair. After prolonged use, slipways are prone to deformation or displacement, necessitating current condition measurements to provide a basis for comprehensive design calculations and facilitate repairs. The width and center position of the slipway at different locations need to be measured. While the center of a surface slipway is relatively easy to determine manually, it is difficult to do so for an underwater slipway due to its inefficiency and safety hazards. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a track clamping device for measuring the center point of a track.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A track clamping device for measuring the center point of a track includes a serrated roller, two serrated tracks, and a rectangular housing. The serrated roller is installed at the center of the rectangular housing and is rotatably connected to the rectangular housing. The two serrated tracks are symmetrically arranged on both sides of the serrated roller and are located inside the rectangular housing. The serrations of the serrated tracks mesh with the serrations of the serrated roller. A rocker arm is installed on the serrated roller and is fixedly connected to the serrated roller by a screw and a nut. The nut has a concave point at its center, which is located at the center of the roller.

[0006] As a preferred technical solution, the sides of the two serrated tracks are provided with a first groove, the inner side of the rectangular shell is provided with a second groove corresponding to each of the first grooves, and a ball bearing is provided between the first groove and the second groove.

[0007] As a preferred technical solution, the horizontal cross-sectional shape of the sawtooth track is L-shaped, and a contact plate is fixed at the outer end.

[0008] As a preferred technical solution, when the contact plates at the outer ends of the two serrated tracks abut against both sides of the slide, the concave point of the screw cap is the center position of the slide.

[0009] As a preferred technical solution, the serrated rollers, serrated tracks, and rectangular housing are all made of aluminum alloy plates.

[0010] As a preferred technical solution, the serrated track has a notch on the side near the serrated roller, and the serrations of the serrated track are set inside the notch.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model relates to a track clamping device for measuring the center point of a track. A rocker arm drives a serrated roller to rotate, which in turn drives the serrated track to slide. This adjusts the length of the two roller tracks so that the outer ends of the two roller tracks are just locked onto the side walls of the track. The nut recess on the rocker arm marks the center point of the track. This improves the efficiency of obtaining the center point of the track and solves the safety hazard caused by the need for manual placement of a leveling rod at the settlement monitoring point of the column.

[0018] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0019] like Figure 1 As shown, a track clamping device for measuring the center point of a track includes a serrated roller 1, two serrated tracks 2, and a rectangular housing 3. The serrated roller 1 is installed at the center inside the rectangular housing 3 and is rotatably connected to the rectangular housing 3. The two serrated tracks 2 are symmetrically arranged on both sides of the serrated roller 1 and are located inside the rectangular housing 3. The serrations of the serrated tracks 2 mesh with the serrations of the serrated roller 1. In this embodiment, the serrated roller 1 is made of a 1cm thick aluminum alloy plate. Figure 2As shown, the serrated roller 1 is fixedly connected to a rocker arm 4 by screws and nuts. There is a concave point in the center of the nut, which is located in the center of the roller.

[0020] In this embodiment, the serrated track 2 is made of a 5mm thick aluminum alloy plate. A notch is provided on the side of the serrated track 2 near the serrated roller 1, and the serrations of the serrated track 2 are located inside the notch. A first groove with a width of 1mm is provided on the sides of both serrated tracks 2.

[0021] In this embodiment, the rectangular outer shell 3 is made of a 6mm thick aluminum alloy plate. The inner side of the rectangular outer shell 3 is provided with a second groove corresponding to each of the first grooves. The width of the second groove is also 1mm. A ball bearing is provided between the first groove and the second groove. By setting the ball bearing, the friction of the serrated track 2 moving inside the rectangular outer shell 3 is reduced. At the same time, the ball bearing, the first groove and the second groove restrict the direction of movement of the serrated track 2.

[0022] like Figure 3 As shown, the horizontal cross-sectional shape of the sawtooth track 2 is L-shaped, and a contact plate 21 is fixed at its outer end. The design of the contact plate 21 facilitates the fit between the outer end of the sawtooth track 2 and the two sides inside the slide.

[0023] When the contact plates 21 at the outer ends of the two serrated tracks 2 abut against the sides of the slide, the concave point of the screw cap is the center position of the slide.

[0024] The serrated track 2 has a notch on one side near the serrated roller 1, and the serrations of the serrated track 2 are located inside the notch. The notch design prevents the serrated track 2 from detaching from the serrated roller 1.

[0025] like Figure 4 As shown, during use, the user rotates the rocker arm 4, causing the serrated roller 1 to rotate, which in turn drives the two serrated tracks 2 to move in opposite directions. This adjusts the extension length of the two roller tracks so that the contact plates 21 at the outer ends of the two roller tracks just abut against the two side walls inside the slide. At this point, the position of the nut recess on the rocker arm 4 is the center position of the slide. This improves the efficiency of obtaining the center point of the slide and reduces the safety hazards caused by manually reaching the column settlement monitoring point to place a leveling rod for settlement monitoring.

[0026] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-creative modifications to this embodiment as needed after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
