Description

Technical Field

[0001] The utility model relates to the field of mountain engineering machinery, in particular to a follow-up braking device of mountain engineering machinery. Background Art

[0002] The construction environment of engineering machinery in mountainous areas is complex and changeable, including plains, mountains, deserts, hills, swamps, and snowfields. Conventional equipment is difficult to meet the requirements of various environments, especially mountainous large slope construction. In mountain construction, the working capacity of conventional equipment will be limited. When constructing on mountainous large slopes, engineering machinery often has problems with insufficient climbing ability, slope working stability, and safety.

[0003] The mountain engineering machinery in the prior art, such as a mountain excavator (CN203246448U) and a mountain excavator with leveling, traction and support functions (CN203808121U), both have fixed claws that cannot move with the equipment, and this fixed grip structure causes great damage to the road surface and destroys the ecological environment.

[0004] The existing mountain excavator with traction and support functions (CN203808121U) has an overly complex anchor structure and requires an additional power system, which increases the cost of the entire machine.

[0005] Therefore, it is necessary to develop a follow-up braking device for mountain engineering machinery, combining the advantages of existing technologies, and adopting a simple structure that can both follow the equipment and provide support, so as to improve climbing ability, slope working stability, and safety. Utility Model Content

It has a simple structure, low control difficulty, easy operation, and high practicality and economy.

[0007] Technical solution: The utility model is a follow-up brake device for mountain engineering machinery, which is characterized by comprising a follow-up brake device body, the follow-up brake device body comprising a mounting bracket, on which a supporting roller and a sprocket wheel are mounted, the supporting roller is connected to the track shoe, a track clamp is provided on the side of the track shoe, the sprocket wheel is connected to the sprocket wheel adjustment plate, and the track shoe is connected to a gravity self-locking mechanism.

[0008] Wherein, a plurality of supporting wheels and a plurality of sprocket wheels are installed on the installation bracket.

[0009] Wherein, the mounting bracket is connected to the rotating bracket, and the rotating bracket is connected to the fixed bracket through an angle-changing oil cylinder.

[0010] Wherein, the rotating bracket is connected to the gravity self-locking mechanism through a pin shaft.

[0011] Wherein, the angle-changing oil cylinder is connected to the fixed bracket and the rotating bracket through a pin shaft.

[0012] Wherein, the gravity self-locking mechanism is provided with a gravity self-locking hook for hooking the track shoe.

[0013] Wherein, the follow-up brake device body is installed on mountain engineering machinery.

[0014] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: The utility model combines the advantages of the prior art and adopts a simple structure that can follow the equipment and support it, thereby improving the climbing ability, slope working stability, and safety. The follow-up brake device can effectively ensure that the mountain engineering machinery equipment does not slide down the slope, greatly improving the safety of the equipment when operating on a large slope. The follow-up brake device increases the effective grounding length of the crawler, so that the center of gravity of the whole machine can fall in a safe area, ensuring the safety and reliability of the construction. At the same time, the follow-up brake device can move with the whole machine, and the gravity self-locking structure can lock the crawler plate in time to prevent sliding down the slope.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model provides a follow-up brake device for mountain engineering machinery, comprising a follow-up brake device body 12, the follow-up brake device body 12 comprising a mounting bracket 1, on which a supporting roller 4 and a supporting sprocket 5 are mounted, the supporting roller 4 is connected to a track shoe 2, a track shoe 2 is provided with a track clamp 3 on the side, the supporting sprocket 5 is connected to a supporting sprocket adjustment plate 6, and the track shoe 2 is connected to a gravity self-locking mechanism 7. Among them, a plurality of supporting rollers 4 and a plurality of supporting sprockets 5 are mounted on the mounting bracket 1. The mounting bracket 1 is connected to a rotating bracket 10, and the rotating bracket 10 is connected to a fixed bracket 9 through an angle-changing oil cylinder 8. The rotating bracket 10 is connected to the gravity self-locking mechanism 7 through a pin shaft. The angle-changing oil cylinder 8 is connected to the fixed bracket 9 and the rotating bracket 10 through a pin shaft. The gravity self-locking mechanism 7 is provided with a gravity self-locking hook for hooking the track shoe 2. The follow-up brake device body 12 is mounted on a mountain engineering machinery 11.

[0023] like Figure 1 , Figure 2 As shown, Figure 1 The following figure is a schematic diagram of the construction of the mountain engineering machinery 11 on a 25-degree super-large slope. The follow-up brake device body 12 can effectively ensure that the mountain engineering machinery 11 does not slide down the slope, greatly improving the safety of the equipment when operating on a large slope. The follow-up brake device body 12 increases the effective ground contact length of the crawler, so that the center of gravity of the whole machine can fall in a safe area, ensuring the safety and reliability of the construction. At the same time, the follow-up brake device body 12 can move with the whole machine, and the track shoe 2 can be locked in time by the gravity self-locking structure 7 to prevent sliding down the slope.

The servo brake device body 12 is composed of a rotating bracket 10, a track shoe 2, a track clamp 3, a supporting roller 4, a supporting chain wheel 5, a gravity self-locking mechanism 7, an angle-changing cylinder 8 and a fixed bracket 9.

The tightness of the track shoe 2 is adjusted by the supporting chain wheel adjustment plate 6, and then the mounting bracket 1 is installed on the rotating bracket 10, and the remaining components are connected by a pin shaft. The gravity self-locking mechanism 7 can hook the track shoe 2 in time through the internal gravity self-locking hook when the whole machine slides, thereby preventing the whole machine from sliding, thereby improving safety.
