Description

Technical Field

[0001] This utility model belongs to the field of track plate technology, specifically relating to a track plate with a winding and positioning effect. Background Technology

[0002] Track shoes are mostly used in equipment with large tonnage, such as excavators, bulldozers, and crawler cranes. Made from structural steel, they can be divided into excavator tracks, bulldozer tracks, etc. The wet track shoes used by bulldozers, commonly known as "triangular tracks," are cast iron tracks. Through contact with the ground, the track shoes provide sufficient traction for the construction machinery, enabling it to travel and operate on various complex terrains, such as muddy, soft, and rugged surfaces, while ensuring machine stability and preventing slippage and rollover.

[0003] In engineering operations or equipment maintenance, track retraction typically relies on a winding method. This process should ideally result in the orderly stacking of tracks, but in practice, it often encounters obstacles due to the structural characteristics of the track pads. Current track pad designs lack dedicated positioning or limiting structures for adjacent track pads. This unconstrained state makes it highly susceptible to lateral shifts or irregular tilting angles between adjacent track pads during winding. Once this misalignment occurs, the misaligned track plates will prevent the subsequent tracks from winding along the preset track of the rollers. At best, this will result in localized loose stacking and uneven gaps; at worst, it will cause the tracks to jam or even become entangled with the winding device. This not only requires frequent manual adjustments, but may also cause deformation of the track plate edges and wear of the chain links due to misalignment and compression, thus shortening the service life of the tracks. Utility Model Content

[0004] The purpose of this invention is to provide a track plate with a winding and positioning effect, which aims to solve the problem that when such misalignment occurs, the misaligned track plate will prevent the subsequent track from winding along the preset track of the roller. This can result in minor issues such as localized loose stacking and uneven gaps, or even serious issues such as jamming or entanglement between the track and the winding device. This not only requires frequent manual adjustments, but may also cause deformation of the track plate edges and wear of the chain links due to misalignment and compression, thus shortening the service life of the track.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a track plate with a winding and positioning effect, comprising a track plate, wherein a horizontal bar is integrally connected to one side of the outer wall of the track plate, and two locking strips are symmetrically welded to the bottom of the track plate; Two notches are symmetrically opened on the surface of the horizontal bar. An arc-shaped opening is opened on the inner wall of each side of the top opening of the notch. A light rod is fixedly installed horizontally on the inner wall of each arc-shaped opening. A movable tongue is movably connected to the outer wall of each light rod.

[0006] In order to enable the movable tongue to open horizontally at the opening end of the notch, as the track plate with the winding and positioning effect of this utility model, preferably, the bottom of the movable tongue is provided with a bottom opening, the inside of the bottom opening is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the inner wall of the arc-shaped opening. One end of the movable tongue is a semi-circular structure, and the optical rod is installed at the center of the semi-circular end of the movable tongue. The movable tongue rotates counterclockwise through the optical rod, and the internal dimensions of the arc-shaped opening are adapted to the dimensions of the movable tongue.

[0007] In order for the clip to be able to fit into the corresponding notch, as the track plate with the winding and positioning effect of this utility model, preferably, the internal size of the notch is adapted to the size of the clip.

[0008] In order to enable the movable tongue to rotate downward and retract into the arc-shaped opening when the locking strip aligns with the notch, as a track plate with a winding and positioning effect of this utility model, preferably, two docking grooves are symmetrically opened on the outer wall of the side of the locking strip that connects with the track plate, and one side of the two docking grooves are connected to each other. The size of the docking groove is adapted to the rotation size of the movable tongue.

[0009] Compared with the prior art, the beneficial effects of this utility model are: After connecting multiple track plates end-to-end to form a track, when the track needs to be wound up, the bottoms of two track plates at corresponding positions will align with the top of another. The two locking strips at the bottom of the upper track plate are pressed into the recesses of the lower track plate. This structure provides positioning during winding, preventing misalignment of the track plates and improving the ease of winding. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 The present invention provides the following technical solution: a track plate with a winding and positioning effect, including a track plate 1, a horizontal bar 2 integrally connected on one side outer wall of the track plate 1, and two locking strips 3 symmetrically welded to the bottom of the track plate 1. Multiple track plates 1 are connected end to end to form a complete track. The specific length of the track can be set according to the requirements of the corresponding equipment, and the appropriate number of track plates 1 can be set to meet the usage requirements.

[0018] Two notches 4 are symmetrically opened on the surface of the horizontal bar 2. An arc-shaped opening 5 is opened on the inner wall of the top opening of each notch 4. A light rod 6 is fixedly installed horizontally on the inner wall of each arc-shaped opening 5. A movable tongue 7 is movably connected to the outer wall of each light rod 6.

[0019] Preferably, the bottom of the movable tongue 7 is provided with a bottom opening 71, the inside of the bottom opening 71 is fixedly connected to one end of the spring 72, and the other end of the spring 72 is fixedly connected to the inner wall of the arc-shaped opening 5. When spring 72 is in its reset state, the movable tongue 7 will open horizontally inside the recess 4. The movable tongue 7 can be rotated clockwise and counterclockwise via the smooth rod 6, and each rotation of the movable tongue 7 will pull on spring 72. Spring 72 is made of alloy material and can maintain good elasticity even after prolonged stretching.

[0020] One end of the movable tongue 7 is a semi-circular structure, and the smooth rod 6 is installed at the center of the semi-circular end of the movable tongue 7. The movable tongue 7 rotates counterclockwise through the smooth rod 6, and the internal dimensions of the arc-shaped opening 5 are adapted to the dimensions of the movable tongue 7.

[0021] In actual use, when the track is wound up, the two track plates 1 at the corresponding upper and lower positions are positioned and installed. Press the upper track plate 1 down, so that the two locking strips 3 at the bottom of the upper track plate 1 will be inserted into the recesses 4 on the corresponding lower track plate 1. When the retaining strip 3 aligns with the notch 4, the retaining strip 3 will first press the movable tongue 7, causing the movable tongue 7 to rotate counterclockwise downwards until it is fully retracted into the arc-shaped opening 5. At this point, the retaining strip 3 can fully enter the notch 4, and the spring 72 will reset after the retaining strip 3 aligns with the notch 4. When the spring 72 returns to its original position, it will push the movable tongue 7 upward. When the movable tongue 7 is pushed by the spring 72, it will rotate on the outer wall of the smooth rod 6. The rotation trajectory of the movable tongue 7 will pass through the inside of the mating groove 31, and finally the movable tongue 7 will open horizontally in the mating groove 31, thereby restricting the locking strip 3 inside the recess 4; Preferably, the internal dimensions of the notch 4 are adapted to the dimensions of the card strip 3.

[0022] Preferably, two docking grooves 31 are symmetrically opened on the outer wall of the side of the card strip 3 that connects to the track plate 1. One side of the two docking grooves 31 is connected to each other, and the size of the docking groove 31 is adapted to the rotation size of the movable tongue 7.

[0023] In practical use, after connecting multiple track plates 1 end to end to form a track, when the track needs to be wound up, the bottoms of two track plates 1 at corresponding upper and lower positions will be aligned with the top of another. The two retaining strips 3 at the bottom of the upper track plate 1 are pressed into the recesses 4 of the lower track plate 1. This structure allows the track to be positioned and wound up during operation, preventing misalignment of the track plates 1 after winding and improving the ease of track winding.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
