Technical Field

[0001] The present invention relates to the field of engineering measurement, and in particular to a track clamping device and method for obtaining a track center point in slideway measurement. Background Art

[0002] The slipway is one of the common hydraulic structures for shipbuilding and repair. After long-term use, the slipway is prone to deformation or displacement. It is necessary to measure the current status of the slipway to provide a certain basis for the composite verification of the design, so as to better repair the slipway. The slipway needs to measure the width and center position of the slipway at different positions. It is easier to obtain the center of the slipway through manual measurement for the water slide, but it is not easy to obtain the position of the center of the underwater slide through manual measurement. Manual measurement is inefficient and has safety hazards. Summary of the invention

[0007] As a preferred technical solution, the horizontal cross-section of the zigzag track is L-shaped, and a contact plate is fixed to the outer end.

[0008] As a preferred technical solution, when the contact plates at the outer ends of the two sawtooth rails abut against the two sides of the slideway, the concave point of the nut is the center position of the slideway.

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

[0022] The technical solution of the present invention is further described below in conjunction with specific implementation methods:

[0023] like Figure 1 As shown, a track measuring device for obtaining the center point of a track comprises a serrated roller 1, two serrated rails 2 and a rectangular housing 3. The serrated roller 1 is installed at the center of the rectangular housing 3. The serrated roller 1 is rotatably connected to the rectangular housing 3. The two serrated rails 2 are symmetrically arranged on both sides of the serrated roller 1. The serrated rails 2 are arranged in the rectangular housing 3. The teeth of the serrated rails 2 are meshed with the teeth of the serrated roller 1. In this embodiment, the serrated roller 1 is made of a 1 cm thick aluminum alloy plate. Figure 2 As shown, the serrated roller 1 is fixedly connected to a rocker 4 through a screw and a nut, and there is a concave point at the center of the nut, and the concave point is located at the center of the roller.

[0024] In this embodiment, the sawtooth track 2 is made of a 5 mm thick aluminum alloy plate, and a notch is provided on one side of the sawtooth track 2 close to the sawtooth roller 1, and the sawtooth of the sawtooth track 2 is arranged inside the notch. The sides of the two sawtooth tracks 2 are both provided with a first groove with a width of 1 mm.

[0025] In this embodiment, the rectangular housing 3 is made of a 6 mm thick aluminum alloy plate, and a second groove corresponding to each first groove is provided on the inner side of the rectangular housing 3, and the width of the second groove is also 1 mm, and a ball is provided between the first groove and the second groove. The ball is provided to reduce the friction of the sawtooth track 2 moving in the rectangular housing 3, and at the same time, the moving direction of the sawtooth track 2 is limited by the ball, the first groove and the second groove.

[0026] like Figure 3 As shown, the horizontal cross-section of the sawtooth track 2 is L-shaped, and a contact plate 21 is fixed to the outer end. The design of the contact plate 21 facilitates the outer end of the sawtooth track 2 to fit with the two sides of the slideway.

[0027] When the contact plates 21 at the outer ends of the two sawtooth rails 2 abut against the two sides of the slideway, the concave point of the screw nut is the center position of the slideway.

[0028] A notch is provided on one side of the sawtooth track 2 close to the sawtooth roller 1, and the sawtooths of the sawtooth track 2 are arranged inside the notch. The design of the notch can prevent the sawtooth track 2 from escaping from the sawtooth roller 1.

[0029] like Figure 4 As shown, a method for using a track clamp device for slideway measurement to obtain a track center point comprises the following steps:

[0030] Step 1: Place the device into the slide;

[0031] Step 2: Shake the rocker 4 to drive the serrated roller 1 to rotate, so that the two serrated tracks 2 extend from the rectangular housing 3;

[0032] Step three, continue to shake the rocker 4 until the contact plates 21 at the outer ends of the two serrated tracks 2 abut against the inner walls on both sides of the slideway. At this time, the concave point of the nut at the connection between the rocker 4 and the serrated roller 1 is the center position of the slideway.

[0033] The use of the device can improve the efficiency of obtaining the center point of the slideway and reduce the potential safety hazards caused by manually reaching the column settlement monitoring point to place a level rod for settlement monitoring.

[0034] This embodiment is only a further explanation of the invention rather than a limitation of the invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the invention, they are protected by the patent law.
