Description

Technical Field

[0001] This utility model relates to the field of logging machine auxiliary equipment technology, and in particular to a limiting device with a buffer function. Background Technology

[0002] Currently, the logging machines on the market have the sawing component and the limiting mechanism directly connected. During logging operations, the sawing component swings back quickly after sawing the wood. The frequent sawing and swinging actions cause the sawing component to violently impact the limiting mechanism each time it swings back. The high speed and impact force during the swinging process cause the sawing component to impact the main frame and frequently pull on the hydraulic cylinder, leading to hydraulic cylinder leakage and damage to the main frame, thus reducing the safety performance and service life of the logging machine.

[0003] Based on this, a limiting device with a buffer function is proposed to solve this problem. Utility Model Content

[0015] The advantages of this utility model compared to the prior art are as follows:

[0016] 1.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0027] like Figure 1-7 As shown, a limiting device with a buffer function includes a logging machine main frame 1. The device is characterized by having a sawing component 2 mounted on the logging machine main frame 1, a limiting plate 3 mounted on the logging machine main frame 1 above the sawing component 2, and a limiting assembly 4 mounted on the upper end of the sawing component 2 between the limiting plates 3. The limiting assembly 4 includes a limiting frame 5, a hexagonal head bolt 6 penetrating the lower end of the limiting frame 5, a limiting washer 7 mounted on the hexagonal head bolt 6 and on the outer wall of the limiting frame 5, a buffer spring 8 mounted inside the limiting frame 5 and on the hexagonal head bolt 6, a flat washer 9 mounted on the hexagonal head bolt 6 and above the buffer spring 8, and several nuts 10 mounted above the flat washer 9. A fixing plate 11 is mounted on the end of the limiting frame 5 near the logging machine main frame 1. The limiting component 4 is installed between the main frame 1 of the logging machine and the sawing part 2 to buffer and limit the logging machine and the sawing part 2. After the sawing part 2 finishes sawing the wood, it swings back quickly. During the operation, the sawing and swinging actions are frequent. The swinging process is fast and has a large impact force. The limiting component 4 greatly reduces the impact of the sawing part 2 on the main frame. At the same time, it can limit the swinging angle and prevent the sawing part 2 from pulling on the hydraulic cylinder, thus protecting the hydraulic cylinder.

[0028] In one embodiment, such as Figure 1 As shown, the limiting plate 3 is provided with a first fixing hole 12, and the fixing plate 11 is provided with a second fixing hole 13. The first fixing hole 12 and the second fixing hole 13 are fixedly connected to the limiting plate 3 and the limiting frame 5 by bolts. A gasket 14 is provided on the first fixing hole 12, and then the first fixing hole 12 and the second fixing hole 13 are connected by bolts 18.

[0029] In one embodiment, such as Figure 5 , Figure 6 As shown, the limiting frame 5 has an inverted trapezoidal structure and a notch 15 is provided in the middle of the limiting frame 5.

[0030] In one embodiment, such as Figure 6 As shown, the distance between the outer wall of the limiting frame 5 and the limiting pad 7 is L.

[0031] In one embodiment, such as Figure 6 , Figure 7 A grease nipple 16 is provided at the lower end of the limiting frame 5 and on the side of the hexagonal head bolt 6.

[0032] In one embodiment, such as Figure 6 As shown, a channel 17 is provided inside the limiting frame 5 and at the end of the grease nipple 16, and the channel 17 is connected to the hexagonal head bolt 6.

[0033] In one embodiment, such as Figure 6 As shown, the thread of the hexagonal head bolt 6 is located at the notch 15, the flat washer 9 is located at the contact position between the notch 15 and the limit bracket 5, and there are two nuts 10.

[0034] The working principle of the limiting device with buffer function of this utility model is as follows: The assembly diagram of the limiting component 4 is shown in the figure. Figure 7 As shown, the limiting component 4 is fixed to the main frame 1 of the logging machine using a washer 14 and a bolt 18 (see...). Figure 1 ).

[0035] like Figure 2 As shown, when the saw part 2 is sawing downwards, the saw part 2 does not contact the limiting component 4, and the buffer spring 8 inside the limiting component 4 is in the extended state.

[0036] like Figure 3 As shown in Figure 4, after the saw part 2 retracts, it impacts the hexagonal bolt head 6 of the limiting assembly 4. At this time, the buffer spring 8 acts as a buffer, reducing the impact of the saw part 2 on the main frame 1 of the logging machine. When the buffer spring is compressed to... Figure 3 The fixing plate 11 is pressed against the main frame 1 of the logging machine, thereby preventing the sawing part 2 from moving upward and achieving the function of limiting movement.

[0037] When the limit component 4 is used for a long time, such as Figure 6 As shown, wear of the buffer spring 8 can be caused by injecting lubricating oil through the grease nipple 16, which then flows into the buffer spring 8 through the channel 17 to lubricate it and alleviate the wear of the buffer spring 8.

[0038] like Figure 1As shown, the limiting component 4 is installed between the main frame 1 of the logging machine and the sawing component 2. It is used for buffering and limiting the logging machine and the sawing component 2. After the sawing component 2 finishes sawing the wood, it swings back quickly. During the operation, the sawing and swinging actions are frequent. The swinging process is fast and has a large impact force. The limiting component 4 greatly reduces the impact of the sawing component 2 on the main frame. At the same time, it can limit the swinging angle and prevent the sawing component 2 from pulling on the hydraulic cylinder, thus achieving the purpose of protecting the hydraulic cylinder.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
