DETAILED DESCRIPTION

[0037] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0038] As shown in the accompanying Figure 1 With the accompanying Figure 7 The track beam overturning mechanism shown in the accompanying drawings comprises a feeding conveying line 3, a feeding conveying line 2 arranged in parallel with the feeding conveying line 3, and a cutting machine 1 arranged at the end of the feeding conveying line 2 and used for cutting the track beam 6.

[0039] The raw material is a 12-meter-long track beam 6, which is packed in bundles, lifted by a trolley, and placed on the feeding conveying line 3. After the track beam 6 is overturned by the overturning mechanism and placed on the feeding conveying line 2, the track beam 6 is ensured to be in the state of tooth surface upward and is sent into the cutting machine 1 by the feeding conveying line 2.

[0040] The feeding conveying line 3 and the feeding conveying line 2 are both drum-type conveying mechanisms, which are not the improved technical scheme of the present application.

[0041] The overturning mechanism is a machine frame 404 in the shape of "L" arranged below the feeding conveying line 3 and the feeding conveying line 2. A turning shaft 405 is rotatably installed on the top of the machine frame 404 through a shaft seat 406. A plurality of pawls 4 are arranged at equal intervals on the turning shaft 405. The pawls 4 are used to drag the bottom surface of the track beam 6 to drive the track beam 6 to overturn. The pawls 4 are parallel to the drum of the feeding conveying line 3 in the initial state.

[0042] A driving arm 407 is also installed on the turning shaft 405 between the intervals of the pawls 4.

[0043] A driving unit one 401 is rotatably installed at the beam position of the bottom of the machine frame 404. The output end of the driving unit one 401 is rotatably connected with the driving arm 407. The driving unit one 401 drives the turning shaft 405 and the pawls 4 to rotate through the driving arm 407, so as to drive the track beam 6 to overturn.

[0044] In order to avoid the pawls 4 from directly hitting the feeding conveying line 2 after driving the track beam 6 to overturn, a support frame 403 is installed on the top of the machine frame 404 through two support ribs 410. The support frame 403 is arranged in an inclined manner on the top of the machine frame 404, and a plurality of support drums 402 are arranged in the middle of the support frame 403. After the pawls 4 drive the track beam 6 to overturn, the track beam 6 leans on the support drums 402. The feeding conveying line 2 moves to feed. The track beam 6 slowly separates from the support drums 402 on the support frame 403 and lies flat on the conveying line to be sent into the cutting machine 1.

[0045] Compared with the existing working mode, the field workers use crowbars to turn over the track beam with the tooth surface facing down, and the single track beam weighs 300 Kg. In order to reduce the labor intensity of production workers, a track beam turning mechanism is designed to assist workers in completing the track beam loading pretreatment, reducing the production preparation work before the track beam enters the cutting machine. The track beam 6 turning mechanism does not need workers to use crowbars to intervene, which reduces the labor intensity of workers, and through the design of the supporting frame 403, the impact on the conveying line drum during the turning process is avoided, and the service life of the conveying line drum is effectively prolonged compared with manual turning.

[0046] As shown in Figure 1 and Figure 2 , the track beam 6 turning mechanism is convenient for the modification of the existing conveying line equipment. A mounting position is provided on the side of the feeding conveying line 3, that is, a gap is provided on the side of the feeding conveying line 3 for setting the rack 404, and an axle bracket 302 is provided on the top of the rack 404 through a heightening piece 303. The axle bracket 302 and the side of the feeding conveying line 3 are provided with a plurality of extension drums 301. After assembly, one end of the extension drum 301 extends into the feeding conveying line 2 area. When the rack 404 is below the feeding conveying line 3, the pawl 4 is located between the spacing of the plurality of extension drums 301. This structure can make the pawl 4 turn over the track beam 6 on the feeding conveying line 3 to the feeding conveying line 2.

[0047] The bottom of the supporting frame 403 is installed with the top of the axle bracket 302.

[0048] A complete break is provided in the middle of the feeding conveying line 2. The rack 404 is provided at the break, that is, the feeding conveying line 2 is divided into two sections and is installed at both ends of the rack 404.

[0049] The turning mechanism can be well used by simply modifying the existing conveying line equipment, which can effectively reduce the cost investment of manufacturers.

[0050] In order to further make the turning mechanism applicable to most conveying lines and convenient to adjust during installation, so that the pawl 4 can accurately turn over the track beam 6 to the feeding conveying line 2, a waist hole 408 structure is provided on the rack 404 at the installation position of the axle seat 406 and the pendulum seat 409. Through the waist hole 408 structure, the axle seat 406 and the pendulum seat 409 can be fixed and installed after being adjusted in position on the rack 404, which can further cooperate with conveying lines of different widths.

[0051] After the track beam 6 is turned over from the feeding conveying line 3 to the feeding conveying line 2, in order to ensure that the track beam 6 can accurately enter the cutting machine 1, the two ends of the feeding conveying line 2 are also provided with push plates 501 driven by the second driving unit 5, the push plates 501 are arranged at the side edges of the feeding conveying line 2, the track beam 6 is horizontally conveyed on the feeding conveying line 2, the track beam 6 is pushed by the push plates 501, and it is ensured that the track beam 6 can accurately enter the cutting machine 1.

[0052] In the utility model, the driving units can adopt cylinders, electric push rods and the like, the pawl 4 is reset to the initial state after completing turning over of the track beam 6 once, and waits for feeding next time.

[0053] Finally, the following points should be explained: firstly, in the description of the present application, it should be explained that, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, which can be mechanical connection or electrical connection, can be the communication between two elements, can be directly connected, "up", "down", "left", "right" and the like are only used to represent the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship can change;
