Due to the road environment reasons where the excavator travels, the chain may be stuck in some mud or stones and cause the chain to fall off. The buckle groove can enhance the cooperation connection between the guide wheel and the crawler track, control the chain in the track, and avoid the phenomenon of chain derailment caused by side slip of the crawler track. At the same time, the limit plate can allow the crawler track to move forward along the guide wheel, and further buckle the chain in the track.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of this application is:

[0021] See also Figures 1 to 5 ,in, Figure 1 This is a schematic diagram of the overall structure of the anti-chain-off guide wheel for engineering machinery according to the first embodiment of the utility model.

Figure 4 This is a schematic structural diagram of the installation assembly of the first embodiment of the present utility model. Figure 5 It is a structural schematic diagram of the limiting component of the first embodiment of the present invention. The present invention provides an anti-chain derailment guide wheel for engineering machinery, including a support wheel 101, an anti-skid component, an installation component and a limiting component. The anti-skid component includes a fixing bar 102, an anti-skid rod 103, a limiting block 104, a return spring 105 and an anti-sliding block 106.

The above-mentioned scheme solves the problem that when the guide wheel for preventing the track from detaching is in use, the track is rigidly connected to the guide wheel, the track is easily broken, and the track is easily damaged and needs to be replaced frequently. It can be understood that the above-mentioned scheme can be used in the scenario of protecting the tracks and chains of engineering machinery, and can also be used to solve the problem of guide wheel installation.

[0022] According to this specific embodiment, the fixing bar 102 is fixedly connected to the support wheel 101 and is located in the middle of the support wheel 101. The number of the anti-slip bars 103 is multiple, and the multiple anti-slip bars 103 are respectively slidably connected to the support wheel 101 and respectively pass through the anti-slip bars 103. The number of the limiting blocks 104 is multiple, and the multiple limiting blocks 104 are respectively fixedly connected to the anti-slip bars 103 and are respectively located inside the support wheel 101. The number of the anti-slip blocks 106 is multiple, and the multiple anti-slip blocks 106 are respectively fixedly connected to the anti-slip bars 103 and are respectively located on the outside of the fixing bar 102. The number of the return springs 105 is multiple, and the multiple return springs 105 are respectively fixedly connected to the anti-slip blocks 106 and are respectively located between the anti-slip blocks 106 and the support wheel 101. The anti-skid block 106 is provided with an anti-skid groove on the surface of the anti-skid block 106 for cooperating with the crawler chain to prevent the crawler chain from falling off the outer side of the support wheel 101 during use. The elastic force provided by the return spring 105 makes the anti-skid block 106 fit with the inner circle of the chain. When the chain rotates to the bottom of the support wheel 101, the elastic force provided by the return spring 105 makes the chain have a certain amount of collapse when contacting the anti-skid block 106, thereby preventing the chain from being broken.

[0023] Among them, a limiting groove 107 is respectively provided on both sides of the support wheel 101, an installation groove 108 is provided in the middle of the support wheel 101, and multiple limiting holes 109 are also respectively provided on both sides of the support wheel 101. The limiting groove 107 provides a limiting effect for the limiting bar 115, and the installation groove 108 is used to provide a limiting effect for the support plate 110. The limiting hole 109 cooperates with the limiting bolt 116 to facilitate the fixation of the limiting component.

[0024] Secondly, the mounting assembly includes a support plate 110 and a support column 111. The support plate 110 is detachably connected to the support wheel 101 and is located inside the mounting groove 108. The support column 111 is fixedly connected to the support plate 110 and passes through the support plate 110 and the support wheel 101. The support plate 110 and the support column 111 provide support and transmission for the support wheel 101.

[0025] Again, the mounting assembly also includes a mounting plate 112 and a mounting bolt 113. The mounting plate 112 is fixedly connected to the support column 111 and is located on the outside of the support column 111. There are multiple mounting bolts 113, and the multiple mounting bolts 113 are respectively threadedly connected to the mounting plate 112 and pass through the mounting plate 112 respectively. The mounting plate 112 provides a connection between the support plate 110 and the support column 111, and the mounting bolts 113 provide support to the mounting plate 112 and the mechanical transmission assembly, so as to facilitate support and transmission of the guide wheel.

[0026] Finally, there are two limit plates 114, which are detachably connected to the support wheel 101 and pass through the support wheel 101 respectively. There are two limit bars 115, which are fixedly connected to the limit plates 114 and located inside the limit slots 107 respectively. There are multiple limit bolts 116, which are threadedly connected to the limit plates 114 and located inside the limit holes 109 respectively. There are multiple blocks 117, and the multiple clamping blocks 117 are respectively fixedly connected to the limit plate 114 and are respectively located on the outside of the limit plate 114. The limit plate 114 is used to provide support for the limit assembly, and the limit bar 115 is used to provide a limiting effect on the limit plate 114. The limit bolts 116 are used to facilitate fixing the limit plate 114 on both sides of the support wheel 101, and the crawler track and chain are fixed to the support wheel 101 through the clamping blocks 117 to prevent the crawler track and chain from derailing.

[0027] The anti-chain derailment guide wheel for engineering machinery of this embodiment is used, and the support wheel 101 is used to connect with the mechanical transmission device and provide support for the crawler track, and the fixing bar 102 is used to provide support and limit the anti-slip block 106, and the anti-slip rod 103 provides support for the anti-slip block 106, and the limit block 104 provides support and limit for the anti-slip rod 103, and the return spring 105 provides elastic force for the anti-slip block 106, and the surface of the anti-slip block 106 is provided with an anti-slip groove for cooperating with the crawler chain to prevent the crawler from slipping. The chain falls off from the outer side of the support wheel 101. When in use, the elastic force provided by the return spring 105 makes the anti-sliding block 106 fit with the inner circle of the chain. When the chain rotates to the bottom of the support wheel 101, the elastic force provided by the return spring 105 makes the chain have a certain amount of contraction when contacting the anti-sliding block 106, avoiding the chain from being broken. This solves the problem that when the guide wheel for preventing the track from detaching is in use, the track is rigidly connected to the guide wheel, the track is easily broken, resulting in the track being easily damaged and needing to be replaced frequently.
