[0019] By adopting the above technical solution, when the clamping plate is clamped on the track, the operator rotates the pressing nut, and the pressing nut pushes the pressing plate to press against the side surface of the track under the support of the support frame, so that the iron tongue is more firmly installed on the track.

DETAILED DESCRIPTION
[0029] The following will be described in detail below with reference to the accompanying drawings. Figures 1-3 The present application is further described in detail.
[0030] The embodiment of the present application discloses a long tongue type windproof limiting device of a large equipment walking mechanism wheel.
[0031] Embodiment 1
[0032] With reference to Figure 1 A long tongue type windproof limiting device of a large equipment walking mechanism wheel comprises an iron tongue 1 and a mounting assembly 2, the bottom of the iron tongue 1 is a plane which is attached to a track, the iron tongue 1 is provided with a guide surface 11, a pressing surface 12 and a limiting surface 13 which are sequentially and continuously arranged along the rolling direction of the wheel, the wheel rolls along the guide surface 11 to the pressing surface 12 and is attached to the limiting surface 13, and the iron tongue 1 is mounted on the track through the mounting assembly 2.
[0033] With reference to Figure 1 The guide surface 11 is a plane which is arranged obliquely to the track and intersects the bottom wall surface of the iron tongue 1, when the wheel rolls on the plane, the contact surface is stable and the resistance received is uniform, thereby improving the stability of the wheel rolling on the iron tongue 1. Through the arrangement of the pressing surface 12, the wheel can roll on the iron tongue 1 for a distance, thereby ensuring that the wheel is completely separated from the track, the pressing surface 12 is a plane which is arranged parallel to the track, the wheel rolls on the pressing surface 12 along the guide surface 11, by arranging the pressing surface 12 into a plane, the change of the speed of the wheel rolling on the iron tongue 1 can be reduced, the impact of the wheel on the iron tongue 1 due to the change of the speed can be reduced, and the stability of the iron tongue 1 can be improved. The limiting surface 13 is an arc surface which has the same curvature as the wheel, the guide surface 11 and the pressing surface 12 are tangent to each other and form a protrusion at the tail of the iron tongue 1 for limiting the rolling of the wheel, the attachment of the wheel to the limiting surface 13 makes the force between the wheel and the iron tongue 1 more uniform. The guide surface 11, the pressing surface 12 and the limiting surface 13 are integrally machined from the iron tongue 1 by wire cutting.
[0034] With reference to Figure 1The mounting assembly 2 in the embodiment comprises two sets of clamping plates 21, which are arranged at the tail of the iron tongue 1 and located on both sides of the iron tongue 1, and each set of clamping plates 21 is welded with the iron tongue 1. The bottom of each set of clamping plates 21 is lower than the bottom of the iron tongue 1, so that a space is formed between the two clamping plates 21, and the width between the two sets of clamping plates 21 is substantially the same as the width of the track. When the iron tongue 1 is placed on the track, the two sets of clamping plates 21 are located on both sides of the track, so as to realize the clamping of the iron tongue 1 and the track. When the iron tongue 1 is installed, the two sets of clamping plates 21 are clamped on the track, thereby improving the convenience of the installation of the iron tongue 1 and the track. The two sets of clamping plates 21 limit the lateral direction of the iron tongue 1, thereby improving the stability of the installation of the iron tongue 1 on the track.
[0035] The implementation principle of the embodiment 1 is that when the wheels on the track are limited, the iron tongue 1 is first placed on the track, the track is inserted between the two sets of clamping plates 21 to complete the clamping, then the wheels are rolled on the pressing surface 12 along the guide surface 11 under the pushing of strong wind, and the rolling is stopped under the limitation of the limiting surface 13. At this time, the weight of the walking mechanism is entirely applied to the iron tongue 1, the friction force is in a proportional relationship with the weight of the wheels pressing on the iron tongue 1, thereby increasing the friction force between the iron tongue 1 and the track, and improving the limiting effect of the iron tongue 1 on the wheels of the walking mechanism.
[0036] Embodiment 2
[0037] With reference to Figure 2 , Figure 3 The difference between the embodiment and the embodiment 1 is that each clamping plate 21 is provided with a abutting plate 22 and a supporting frame 23, a through hole is formed in each clamping plate 21, the abutting plate 22 is inserted into the through hole and is in sliding connection, the supporting frame 23 is fixedly arranged on the clamping plate 21, a guide rod 24 is fixedly arranged on each abutting plate 22, the guide rod 24 penetrates through the supporting frame 23 and is in sliding connection, an abutting spring 25, a driving plate 26 and an abutting nut 27 are sleeved on each guide rod 24, the abutting nut 27 is in threaded connection with the guide rod 24, the driving plate 26 is in sliding connection with the guide rod 24, the abutting spring 25 is located between the driving plate 26 and the abutting plate 22, the abutting nut 27 is located between the driving plate 26 and the supporting frame 23, and the supporting frame 23 supports the abutting nut 27 towards the track. When the iron tongue 1 is clamped on the track, the operator rotates the abutting nut 27, the abutting nut 27 is pushed by the guide rod 24 to abut against the track laterally under the support of the supporting frame 23, thereby improving the firmness of the installation of the iron tongue 1 on the track.
[0038] With reference to Figure 2 , Figure 3The tongue 1 is provided with a driving cavity 31, and a driving rod 32 is slidingly inserted into the tongue 1. The driving rod 32 is arranged along a direction perpendicular to the track. One end of the driving rod 32 extends out of the limiting surface 13, and the other end is inserted into the driving cavity 31. The driving rod 32 is connected with each driving plate 26 through a connecting rod set 33. The connecting rod set 33 in the embodiment includes a first connecting rod 331 and a second connecting rod 332. The second connecting rod 332 is an L-shaped rod. One end of the second connecting rod 332 is inserted into the driving cavity 31 and is slidingly connected with the tongue 1. The other end of the second connecting rod 332 is fixedly connected with the driving plate 26. One end of the first connecting rod 331 is hingedly connected with the end of the driving rod 32 inserted into the driving cavity 31. The other end of the first connecting rod 331 is hingedly connected with the end of the second connecting rod 332 inserted into the driving cavity 31. When the wheel approaches the limiting surface 13, the wheel extrudes the driving rod 32 to slide. The driving rod 32 pulls the second connecting rod 332 to slide towards the track through the first connecting rod 331. The second connecting rod 332 drives the driving plate 26 to compress and abut against the spring 25 towards the track, thereby increasing the friction between the abutting plate 22 and the track and improving the limiting effect of the tongue 1 on the wheel.

Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
