The drive wheel 120 is mounted at the junction of the first section 1521 and the second section 1523. The whole first support frame 152 is approximately in a herringbone shape, in the whole first support frame 152, the end, which is far away from the first section 1521, of the second section 1523 most likely to collide with the second support frame 154 is provided with the shock absorbing piece 156, so that the first support frame 152 can be prevented from directly colliding with the second support frame 154, the damping of the vibration of the whole walking device 100 can be accelerated, the shock absorbing effect is achieved, the damage of the impact load to the whole walking device 100 is reduced, and the service life of the walking device 100 is prolonged.

In this embodiment, under the condition that the running device 100 is subjected to an impact load, the first support frame 152 and the second support frame 154 rotate relatively with respect to the joint therebetween, so that the second support section 1543 and the second section 1523 rotate toward each other, and after the second section 1523 rotates to contact with the shock absorbing member 156, the shock absorbing member 156 is gradually compressed, and the second support section 1543 is prevented from directly contacting with the second section 1523 under the action of the shock absorbing member 156.
Wherein, the driving wheel 120 is installed at the connection of the first section 1521 and the second section 1523 through a U-shaped bolt.

The driving wheel 120, the guiding wheel 130 and the tensioning wheel 140 form a triangle under the supporting action of the first supporting frame 152 and the second supporting frame 154, so that the connecting belt forms a triangle approximately, and the stability of the whole walking device 100 in the movement process can be improved by maintaining the triangle.
In the present embodiment, the supporting structure 150 further includes a connecting assembly 160, the connecting assembly 160 is disposed between the first supporting frame 152 and the second supporting frame 154, and the shock absorbing member 156 is disposed between the connecting assembly 160 and the second supporting frame 154.
In the embodiment, the connecting member 160 is disposed between the first supporting frame 152 and the second supporting frame 154, and when the walking device 100 shakes, the connecting member 160 contacts the damping member 156 to compress the damping member 156.
In this embodiment, the connecting assembly 160 disposed between the first support frame 152 and the second support frame 154 can support the first support frame 152 and the second support frame 154, and during the rotation of the first support frame 152 and the second support frame 154 in the direction close to each other, the connecting assembly 160 can also play a role in buffering, so as to relieve the pressure of the shock absorbing member 156, and enable the whole walking device 100 to bear a larger impact load.
Further, the connecting assembly 160 includes a contact member 162 and a connecting member 164 rotatably connected, the contact member 162 is connected to the first support bracket 152, the connecting member 164 is connected to the second support bracket 154, and the damping member 156 is disposed between the contact member 162 and the second support bracket 154.
In this embodiment, the contact member 162 is rotatably connected to the connecting member 164, and when the second section 1523 moves in a direction approaching to the second supporting section 1543, the contact member 162 rotates relative to the connecting member 164, and the connecting member 164 can play a certain role in buffering, so as to relieve the pressure of the shock absorbing member 156, and enable the whole walking device 100 to bear a larger impact load.
The contact member 162 is rotatably connected to the first support bracket 152, and the connection member 164 is rotatably connected to the second support bracket 154. That is, the connection manner of the connecting member 164 and the second support frame 154 and the connection manner of the contact member 162 and the first support frame 152 are both flexibly connected, and in the process that the first support frame 152 and the second support frame 154 move in the direction close to each other, the contact member 162 and the connecting member 164 rotate relatively, so that the attenuation of the vibration of the whole walking device 100 can be reduced, the damping effect is improved, and the service life of the whole walking device 100 is prolonged.
In the embodiment, the contact member 162 has a contact surface 163, and the contact surface 163 can contact with the shock absorbing member 156, so that the contact surface 163 contacts with the shock absorbing member 156 under the condition that the traveling device 100 is subjected to the impact load, and the contact area can be increased, so that the impact load can be quickly transmitted to the shock absorbing member 156, and the traveling device 100 can quickly absorb the shock.
Further, the connecting member 164 includes a first connecting section 166 and a second connecting section 168 rotatably connected to each other, the first connecting section 166 is rotatably connected to the contact member 162, and the second connecting section 168 is rotatably connected to the second supporting frame 154.
Since the distance between the first support bracket 152 and the second support bracket 154 is relatively large, after the contact member 162 rotates to an extreme position relative to the connection member 164, there may be a problem that the contact member 162 cannot contact the shock absorbing member 156, and at this time, if the impact load is not attenuated, the connection member 164 is easily damaged. The connecting member 164 is provided with a first connecting section 166 and a second connecting section 168 which are rotatably connected with each other, so that the whole connecting member 164 can provide a larger rotating range in the process of receiving impact load, and the first supporting frame 152 can contact the damping member 156 to achieve the damping effect.
It is easily understood that, in the present embodiment, the connecting member 164 includes a first connecting section 166 and a second connecting section 168 that are rotatably connected to each other, but is not limited thereto, and in other embodiments of the present invention, the connecting member 164 may further include a third connecting section and a fourth connecting section, the third connecting section and the fourth connecting section are rotatably connected to each other, and the number of the connecting sections may be set according to the distance between the first mounting bracket 180 and the second mounting bracket 180.
The walking device 100 further comprises a plurality of supporting wheels 170 and a mounting frame 180, the supporting wheels 170 are mounted on the mounting frame 180, the mounting frame 180 is connected with the second supporting frame 154, the supporting wheels 170 are mainly used for supporting the weight of the whole walking device 100, the supporting wheels 170 are sequentially mounted on the first supporting section 1541, the structure of the supporting wheels 170 and the structure of the guide wheel 130 can be completely the same, and the supporting wheels 170 are arranged below the first supporting section 1541, so that the size of the supporting wheels 170 is smaller than that of the guide wheel 130. In other words, the thrust wheel 170 is obtained by scaling down the guide wheel 130.
Referring to fig. 3, in the present embodiment, the guide wheel 130 includes a wheel 132 and a hub 134, the wheel 132 is sleeved on the hub 134, and the hub 134 is fixed on the second support frame 154 through a U-shaped bolt. By adopting the maintenance-free bearing unit, the oil leakage can be avoided, the maintenance cost is reduced, and the full-life mileage can be realized.
Referring to fig. 4, in the embodiment, the walking device 100 further includes a tensioning assembly 190, and the tensioning assembly 190 is respectively connected to the first supporting frame 152 and the tensioning wheel 140 for maintaining the tensioning force of the tensioning wheel 140 at a preset pressure. The tensioning assembly 190 is connected to the first support frame 152 and the tensioning wheel 140 respectively, so that the tensioning wheel 140 can be kept at a stable preset pressure, and the problem that the belt is detached from the connecting belt due to the tension change in the process of impact load of the running device 100 is avoided, thereby improving the working effect of the running device 100.

The connecting valve 193 communicates the accumulator 192 with the tensioning cylinder 191, and the tensioning cylinder 191 abuts against the tensioning wheel 140 and the first support frame 152 respectively, so that tensioning force is provided for the tensioning wheel 140. When the traveling device 100 receives an impact load, hydraulic oil in the tensioning cylinder 191 flows into the accumulator 192 through the hydraulic oil pipe 194 under the action of the impact load. After the impact load is cancelled, under the action of the energy accumulator 192, the hydraulic oil in the energy accumulator 192 returns to the tensioning oil cylinder 191 again, so that the tensioning oil cylinder 191 can improve the stable tensioning force, the tensioning force of the tensioning wheel 140 can be stabilized at the preset pressure, and the risk of towing of the connecting belt is reduced.
In this embodiment, the tensioning assembly 190 further comprises a pressure gauge 195, and the pressure gauge 195 is mounted on the connecting valve 193 and is mainly used for detecting the pressure value of the hydraulic oil in the hydraulic oil cylinder, which can be observed by an operator.

In summary, in the traveling device 100 provided in the present embodiment, the transmission belt 110 is sequentially wound around the driving wheel 120, the guide wheel 130 and the tension wheel 140, and the driving wheel 120 can drive the guide wheel 130 and the tension wheel 140 to move through the transmission belt 110, so that the traveling device 100 moves forward or backward. In the process of advancing or retreating the walking device 100, the shock absorbing member 156 arranged between the first support frame 152 and the second support frame 154 can avoid the first support frame 152 and the second support frame 154 from directly contacting, and in the process of the movement of the walking device 100, the first support frame 152 and the second support frame 154 are buffered, so that the vibration of the walking device 100 can be attenuated under the condition of receiving larger impact load, and the shock absorbing function is achieved, thereby reducing the damage of an impact carrier to the walking device 100 and prolonging the service life of the walking device 100.
