It is widely used in construction, manufacturing, and transportation, primarily for lifting, installing, and transporting materials and personnel, significantly improving labor productivity. However, in the prior art, the traveling mechanism of a crane lacks protection during operation and is easily damaged by impacts, affecting its use.

[0003] Therefore, this application proposes a crane traveling mechanism protection device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies where the traveling mechanism of a crane lacks protection during operation, is easily damaged by impact, and affects its use, and to propose a crane traveling mechanism protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crane traveling mechanism protection device includes a traveling mechanism connected to the crane and a connecting plate;

[0007] A buffer plate, which is slidably connected to the top of the connecting plate;

[0008] A positioning plate, which is slidably connected to the top of the walking device;

[0009] A support plate, which is fixedly connected to the top of the walking device;

[0010] The connecting mechanism includes a control plate, a pull plate, a vertical plate, an adjusting plate, and an auxiliary plate. The control plate is slidably connected to the front side of the support plate, the pull plate is rotatably connected to the top of the control plate, the vertical plate is slidably connected to the right side of the support plate, and the front side of the vertical plate is rotatably connected to the rear side of the pull plate. The adjusting plate is fixedly connected to the top of the vertical plate, and the auxiliary plate is slidably connected to the top of the support plate, and the bottom of the auxiliary plate is fixedly connected to the top of the positioning plate.

[0011] As a preferred embodiment of this utility model, the right side of the auxiliary plate is an inclined surface, and a second spring is fixedly connected to the left side of the auxiliary plate. One end of the second spring is fixedly connected to the top of the walking device.

[0012] As a preferred embodiment of this utility model, a No. 3 spring is fixedly connected to the right side of the buffer plate, and one end of the No. 3 spring is fixedly connected to the left side of the connecting plate. Contact plates are fixedly connected to both the front and rear sides of the buffer plate, and the sides of the two contact plates that are close to each other are in active contact with the front and rear sides of the walking device.

[0013] In a preferred embodiment of this utility model, a limiting plate is slidably connected to the left side of the control plate, and a No. 1 spring is fixedly connected to the rear side of the limiting plate, with one end of the No. 1 spring fixedly connected to the front side of the control plate.

[0015] As a preferred embodiment of this utility model, the right side of the connecting plate is provided with two connecting holes, and the positioning plate is movably connected to the two connecting holes.

[0016] Beneficial effects:

[0017] 1. By inserting the connecting plate with the buffer plate into the walking device, the control plate can be pulled to the right to move the control plate, which in turn can pull the pull plate to move forward.

[0018] 2. When the vertical plate moves, it can simultaneously drive the adjusting plate to move. At this time, the movement of the adjusting plate can cause the rotating wheel to contact the inclined surface of the auxiliary plate, thereby controlling the auxiliary plate to move to the left.

As the positioning plate moves, it can connect with the connecting hole of the connecting plate to position the connecting plate.

[0019] 3. The movement of the control plate drives the movement of the limiting plate. When the limiting plate is released from the front of the support plate, the first spring is initially in a stretched state, which can pull the limiting plate to move backward, thereby limiting the movement of the control plate and achieving the effect of fixing the connecting plate. By fixing the connecting plate, the buffer plate is connected simultaneously, achieving the effect of rapid assembly.

[0020] In this utility model: by inserting the connecting plate with the buffer plate into the walking device, the control plate is pulled to move the device, the positioning plate connects the connecting plate, and the limiting plate is fixed at the same time. By fixing the connecting plate, the buffer plate is connected simultaneously, achieving a quick assembly effect. At the same time, the buffer plate is cushioned by a No. 3 spring when it is impacted, thus protecting the walking device. Attached Figure Description

[0034] As a preferred embodiment of this utility model, the right side of the auxiliary plate 8 is an inclined surface, and a second spring 9 is fixedly connected to the left side of the auxiliary plate 8. One end of the second spring 9 is fixedly connected to the top of the walking device 1. By setting the second spring 9, the second spring 9 can control the auxiliary plate 8 to return to its original position.

[0035] As a preferred embodiment of this utility model, a No. 3 spring 15 is fixedly connected to the right side of the buffer plate 13, and one end of the No. 3 spring 15 is fixedly connected to the left side of the connecting plate 11. Contact plates 12 are fixedly connected to both the front and rear sides of the buffer plate 13, and the sides of the two contact plates 12 that are close to each other are in contact with the front and rear sides of the walking device 1. By setting the contact plates 12, the contact plates 12 make contact with the walking device 1, which facilitates the control of the buffer plate 13 to move laterally. At the same time, by setting the No. 3 spring 15, the No. 3 spring 15 supports the buffer plate 13 and achieves the buffering effect.

[0036] As a preferred embodiment of this utility model, a limiting plate 3 is slidably connected to the left side of the control plate 14, and a first spring 4 is fixedly connected to the rear side of the limiting plate 3. One end of the first spring 4 is fixedly connected to the front side of the control plate 14. By setting the first spring 4, the first spring 4 is initially in a stretched state, which facilitates pulling the limiting plate 3 to move backward.

[0037] As a preferred embodiment of this utility model, the bottom of the adjusting plate 7 is rotatably connected to a rotating wheel, and the rotating wheel is in active contact with the inclined surface of the auxiliary plate 8.

[0040] The working principle of this utility model is as follows: In actual operation, by inserting the connecting plate 11, which is connected to the buffer plate 13, into the walking device 1, the control plate 14 is pulled to the right. The control plate 14 can then pull the pull plate 5 to move. At the same time, the pull plate 5 can simultaneously pull the vertical plate 6 forward. When the vertical plate 6 moves, it can simultaneously drive the adjusting plate 7 to move. The movement of the adjusting plate 7 can adjust the rotating wheel to contact the inclined surface of the auxiliary plate 8, thereby controlling the auxiliary plate 8 to move to the left. When the auxiliary plate 8 moves, it can drive the positioning plate 10 to move to the left. The position plate 10 moves, and the positioning plate 10 can connect with the connecting hole of the connecting plate 11 to position the connecting plate 11. At the same time, the control plate 14 moves, driving the limiting plate 3 to move. When the limiting plate 3 is disengaged from the front side of the support plate 2, the first spring 4 is initially in a stretched state, which can pull the limiting plate 3 to move backward, thereby limiting the movement of the control plate 14 and achieving the effect of fixing the connecting plate 11. By fixing the connecting plate 11, the buffer plate 13 is connected simultaneously, achieving the effect of quick assembly. At the same time, when the buffer plate 13 is impacted, it is buffered by the third spring 15 to protect the walking device 1.
