Abstract
Description
Technical Field
[0001] The utility model relates to a track frame for a small-sized gas cutting machine to travel, belonging to the technical field of mobile cutting equipment. Background Art
[0002] When cutting metal plates, a small gas cutting machine is often used to perform gas high-temperature cutting. The specific method is to use a staircase-shaped double-track track for the gas cutting machine to travel on, and place the double-track track on the plate along the cutting direction. When cutting, the gas cutting machine cuts while traveling on the double-track track.
[0003] The cutting starts on one side of the plate, and then the track frame and the gas cutting machine are gradually retracted to the other side. The retraction method is to manually drag the track frame, and the amount of retraction is determined by the width of the cut. Generally, the track frame is dragged to the approximate position first, and then the two ends of the iron plate are measured with a ruler, and then the track frame is moved according to the specific position determined by the measurement. The disadvantage of this is that the dragging distance cannot be directly determined, the placement position cannot be accurately placed at one time, and the operation is time-consuming and laborious.
[0004] In addition, when the track frame retreats to the rear edge, the track frame can no longer be completely placed on the metal plate. Only the front side of the track frame is still on the metal plate, and the rear side is already suspended. In order to level the track frame, the operator has to choose some suitable pads to pad under the rear side of the track frame. Since the ground of the machining site is easy to be damaged, the ground is inevitably uneven in some parts, and it is sometimes difficult to find pads of appropriate thickness, making the leveling process very laborious. Utility Model Content
[0005] The technical problem to be solved by the utility model is mainly: when the track frame is moved backward, how to drag the track frame to the right position at one time.
[0006] In view of the above problems, the technical solution proposed by the utility model is:
[0007] A track frame for a small gas cutting machine to travel comprises a front side rail and a rear side rail which are parallel to each other, and a crossbeam which connects and fixes the front side rail and the rear side rail. Both ends of the track frame are respectively provided with a retractable measuring ruler.
[0008] A hanging plate is provided at the front end of the measuring ruler, which is vertically downward and is used for hanging the front side edge of the cut metal plate.
[0009] The measuring ruler is a measuring tape that can be automatically rolled up in a ruler box.
[0010] A ruler box installation position for placing and fixing the ruler box is provided on the rear side of the track frame.
[0011] A ruler slot for a measuring ruler to pass through is arranged at both ends of the front side rail and the rear side rail close to the bottom of the rail, and the notches of the ruler slots at both ends of the front side rail and the rear side rail are respectively located at the ends of the two ends of the front side rail and the rear side rail.
[0012] The upper and lower heights of the hanging plate are greater than the upper and lower spacings of the ruler grooves, and the hanging plate in a standby state hangs on the front side edge of the bottom of the front side rail.
[0013] A longitudinal beam parallel to the rear side rail is also installed on the rear side of the track frame. A plurality of threaded through holes are arranged at equal intervals on the longitudinal beam. Bolts are screwed into the threaded through holes and used to adjust the height of the rear side of the track frame. Beneficial Effects
[0014] 1. The built-in retractable measuring ruler can be used to easily achieve accurate positioning when dragging the track frame backwards, saving time and trouble;
[0015] 2. When the track frame is dragged backwards until the rear side is suspended in the air, it can be leveled by turning the bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings: Embodiment 1
[0021] like Figure 1 , 2 As shown, a track frame for a small gas cutting machine 9 to travel includes a front side rail 1 and a rear side rail 2 that are parallel to each other, and a crossbeam 3 that connects and fixes the front side rail 1 and the rear side rail 2. A retractable measuring ruler 601 is also provided at both ends of the track frame. When in use, the front end of the measuring ruler is aligned with the front side of the metal plate 10 and maintained, and then the track frame is dragged backward, and the measuring ruler 601 is extended. When the extended length of the measuring ruler 601 is consistent with the set value, it means that the track frame has been retracted to the right position and the dragging stops. In this way, the track frame can be dragged backward to the right position at one time, which is very convenient and saves trouble and time.
[0022] A hanging plate 6011 is provided at the front end of the measuring ruler 601 and is used to hang the front edge of the cut metal plate 10 , so as to keep the starting end of the reading of the measuring ruler 601 flush with the front edge of the metal plate 10 .
[0023] like Figure 3 As shown, the measuring ruler 601 is a commercially available measuring tape 6 that can be automatically rolled up in a ruler box 602. A ruler box mounting position 7 for placing and fixing the ruler box 602 is provided on the rear side of the track frame.
[0024] like Figure 2 As shown, ruler slots 8 for the measuring ruler 601 to pass through are provided at both ends of the front side rail 1 and the rear side rail 2 close to the bottom of the rails, and the notches of the ruler slots 8 at both ends of the front side rail 1 and the rear side rail 2 are respectively located at the ends of the front side rail 1 and the rear side rail 2, so that the measuring ruler 601 of the tape measure 6 can be horizontally inserted into the ruler slot 8 from the notch.
[0025] The upper and lower heights of the hanging plate 6011 are greater than the upper and lower spacings of the ruler slot 8, and the hanging plate 6011 in the standby state hangs the front side of the bottom of the front side rail 1. That is, after each use, the measuring ruler does not need to be completely retracted into the ruler box 602, so that it is convenient to draw it out for use next time. Embodiment 2
[0026] like Figure 3 As shown, a longitudinal beam 4 parallel to the rear side rail 2 is further installed on the rear side of the track frame, and a plurality of threaded through holes are provided at equal intervals on the longitudinal beam 4, and bolts 5 for adjusting the height of the rear side of the track frame are screwed into the threaded through holes. In this way, when the track frame moves backward to the rear side and is suspended in the air, the bolts 5 can be activated and the height of the bolts 5 extending downward can be adjusted to provide leveling support for the track frame.
[0027] Preferably, the ruler box mounting positions 7 are arranged at both ends of the longitudinal beam 4 .
[0028] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the protection scope of the present invention. Any modifications in equivalent forms should be regarded as falling within the protection scope of the present invention.
