DETAILED DESCRIPTION

[0028] In order to better explain the utility model, in order to facilitate understanding, the utility model is described in detail below by specific embodiments in conjunction with the drawings.

[0029] As Figure 1 Indicated, the walking device for the open continuous coal mining machine of the embodiment, including main frame 1 and two walking mechanisms 2, two walking mechanisms 2 are respectively parallelly correspondingly installed on the two side walls of main frame 1.

[0030] Specifically, as Figure 3 And Figure 4 Indicated, walking mechanism 2 all includes two drive mechanisms 21, two drive wheels 22, track and installation assembly 23, installation assembly 23 is installed on the side wall of main frame 1 by connecting piece 5, two drive wheels 22 are rotatably installed on the front and rear ends of installation assembly 23, track is sleeved on the outer wall of two drive wheels 22, two drive mechanisms 21 are connected with two drive wheels 22 one by one and simultaneously drive two drive wheels 22 to rotate to drive track to rotate. By setting two walking mechanisms 2, and installing two drive mechanisms 21 and two drive wheels 22 on each walking mechanism 2, it can realize that one independent drive mechanism 21 is set for each drive wheel 22, realizes four-wheel drive, that is, four drive wheels 22 simultaneously provide power, greatly improves the traction, improves the stability of walking device, satisfies even if the tonnage of open continuous coal mining is too large, walking device's continuous walking is also guaranteed, not only improves the coal mining amount, but also can improve the overload capacity of coal mining machine. Moreover, even in complex terrain and harsh environment, walking device can normally walk, even if one of drive mechanisms 21 fails, other drive mechanisms 21 can still work, ensure the continuous operation of walking device, improve walking adaptability and reliability. It needs to be explained that the rotating speed of four drive mechanisms 21 when driving four drive wheels 22 respectively is same, avoids track jam.

[0031] Further, as Figure 3 And Figure 4As shown, the driving mechanism 21 comprises a driving member 211 and a speed reducer 212. The driving wheel 22, the driving member 211 and the speed reducer 212 are all installed in the mounting assembly 23, which reduces the influence of external environmental factors such as dust, moisture and the like on the driving wheel 22, the driving member 211 and the speed reducer 212, thereby improving the reliability and durability of the system. The driving member 211 is connected with the driving wheel 22 through the speed reducer 212. The driving member 211, the speed reducer 212 and the driving wheel 22 are coaxially arranged. By arranging the driving member 211 and the speed reducer 212, the speed reducer 212 can increase the output torque of the driving wheel 22, so that it can better cope with the operation requirements under heavy load and complex terrain conditions. In addition, the speed reducer 212 can select a suitable speed reduction ratio according to the specific working conditions, further enhancing the adaptability and flexibility of the walking device. Preferably, the driving member 211 is a hydraulic motor, which can provide extremely high starting torque and continuous working torque, provide greater power output, and at the same time ensure smooth and rapid response of the track movement. Compared with an electronic motor, the hydraulic motor can work in complex working conditions such as wading, reducing problems caused by electrical faults. When the walking device needs to work, the four driving members 211 are started to rotate synchronously, and at the same time the speed of the driving member 211 is reduced through the speed reducer 212 to increase the torque, so as to drive the four driving wheels 22 to rotate at the same speed, thereby driving the track to rotate and realizing the walking of the walking device.

[0032] Further, as shown in Figures 2-3 The mounting assembly 23 comprises a walking frame 231 and two mounting frames 232. The walking frame 231 is installed in parallel with the side wall of the main frame 1 through the connecting piece 5, which ensures the stability of the walking mechanism 2, not only provides sufficient support for the main frame 1, but also ensures the stable operation of the walking mechanism 2 under various working conditions, reduces mechanical damage caused by vibration or impact, and improves the overall reliability of the walking device. The two mounting frames 232 are respectively installed at the front and rear ends of the walking frame 231, and the driving wheel 22, the driving member 211 and the speed reducer 212 are all installed in the mounting frame 232, and the mounting frame 232 forms a closed protection environment, effectively isolating the influence of external dust, moisture and other harmful substances. Preferably, the mounting frame 232 is in an arc shape. Among them, the end of the mounting frame 232 away from the walking frame 231 is in an arc shape, which can avoid collision between the track and the mounting frame 232, so that the track is more smooth when passing around the driving wheel 22, reducing the friction and jamming between the track and the mounting frame 232.

[0033] Further, as shown in Figure 4As shown, the track is provided with a plurality of clamping grooves. The circumferential outer wall of the driving wheel 22 is provided with a plurality of clamping blocks 221, which are arranged in a circumferential array with the axis of the driving wheel 22 as the center, and the plurality of clamping blocks 221 are exposed to the mounting frame 232. When the driving wheel 22 rotates, the plurality of clamping blocks 221 can be matched with the plurality of clamping grooves one by one to drive the track to rotate, ensuring that the driving wheel 22 can directly and accurately drive the track to move when rotating, providing higher reliability and more stable power transmission, and reducing the risk of slipping.

[0034] Further, as shown, Figures 2-4 The walking device further includes a chain sprocket 3 and a connecting frame 6. The chain sprocket 3 is rotatably mounted on the walking frame 231 through the connecting frame 6, and the chain sprocket 3 is located above the walking frame 231, and the inner wall of the track can be fitted with the outer wall of the chain sprocket 3, which is used to support the track, so as to effectively support the upper part of the track, prevent the track from sagging during operation due to its own weight or load, and ensure that the track maintains proper tension and correct running trajectory, thereby improving the stability and reliability of the walking system. Preferably, a plurality of chain sprockets 3 are provided, which are arranged at equal intervals and coaxially, which can ensure that the track is uniformly supported, so that the track runs more smoothly during operation, reduces bumps and vibrations, and at the same time, the chain sprocket 3 and the track form rolling friction, reducing the frictional resistance between the track and the walking frame 231.
