will the utility model discloses a leg type crawler travel unit is connected with amphibious silt remover, mainly has three kinds of mode: a four-legged walking mode, a crawler walking mode, and a transport/sailing mode.
In the four-leg walking mode, four independently operated walking devices of the four independently operated walking devices need to move in sequence to finish walking, if the walking device moves forwards, the walking device positioned in front of the machine body 5 is lifted at first, the rest three walking devices move forwards for a certain distance through the movement of the crawler wheel joints 8 to push the equipment to move forwards, then the first walking device is dropped to support the ground, and then the rest walking devices are lifted in sequence to move forwards to finish the forward displacement of one station.
The lifting and lowering action of the traveling device is performed by a leg joint hydraulic motor 13 installed at the excavating equipment, the leg joint hydraulic motor 13 enables lifting and lowering by driving the boom 10, and the boom 10 and the crawler wheel joint 8 rise and fall at the same time. After the front supporting leg completes the lifting task, the crawler wheel joints 8 of the other three supporting legs start to rotate, and the effect displayed on the equipment is the forward movement of the equipment. Then, the rest three support legs are sequentially lifted, the position of the crawler wheel joint 8 is reset, the support legs are dropped by the support leg joint hydraulic motor 13, and the forward movement of the machine body can be continuously completed by sequentially circulating the actions.
In the walking mode, the smallest acute end of the track is in contact with the ground, and the other two sides leave the ground in a standing posture. When the machine body needs to walk forwards or backwards, one of the four supporting legs is lifted, and then the rest three supporting legs push the machine body to move forwards for a certain distance, and the lifted supporting legs are put down, so that the forward movement is completed.
Under the walking mode, the action process of the rise and fall of the crawler wheels is as follows: the support leg joint hydraulic motor 13 drives a support leg driving gear 16, the support leg driving gear 16 drives a support leg driven gear 17 to rotate through tooth meshing, the support leg driven gear 17 drives a support leg joint shaft 14 to move through a key, the support leg joint shaft 14 drives a rotating arm 10 to rotate around a shaft through a key, the other end of the rotating arm 10 is connected with a crawler wheel joint shaft 6, and therefore when the rotating arm 10 is driven to rotate around the support leg joint shaft 14 clockwise and anticlockwise, the crawler wheel can be driven to rise and fall.
In the walking mode, the action process that the supporting legs push the machine body to advance is as follows: the crawler wheel joint hydraulic motor 18 drives a crawler wheel joint driving gear 23 to rotate, the crawler wheel joint driving gear 23 drives a crawler wheel joint driven gear 9 to rotate through tooth meshing, the crawler wheel joint driven gear 9 drives a crawler wheel joint shaft 6 to rotate through a key, force and motion are transmitted between the crawler wheel joint shaft 6 and a rotating arm 10 through a key, the rotating arm 10 is connected with a supporting leg joint shaft 14, the supporting leg joint shaft 14 transmits the force and the motion to the machine body 5 through a support 11, and the forward motion of the machine body is completed through synchronous cooperation of three supporting legs. And then, lifting the supporting legs in sequence, and pushing the machine body to advance by the other three supporting legs, thereby completing the continuous advance of the machine body.
The utility model discloses also can use the track to walk, the landing leg joint hydraulic motor 13 and the articulated hydraulic motor 18 of athey wheel of four landing legs adjust simultaneously and control the joint on athey wheel and ground and adjusting device self height and level this moment, guarantee the security and the trafficability characteristic of equipment. Then the hydraulic motor 15 drives the driving wheel 24 to rotate, the driving wheel 24 drives the crawler belt 22 to rotate, and the crawler belt 22 finishes walking by utilizing the friction force with the ground.
Under the crawler travel mode, the contact of crawler wheel long limit and ground this moment, the motion process of marcing is: the hydraulic motor 25 drives the driving wheel 24 to rotate, the driving wheel 24 drives the crawler belt 22 to rotate through meshing, the crawler belt 22 completes forward movement or backward movement by utilizing friction force between the crawler belt 22 and the ground, in the process, the supporting wheel 20 plays a role of expanding the crawler belt 22, force and movement in the forward and backward movement process of the crawler belt 22 are transmitted to the support plate 21 through the supporting wheel shaft 19, the support plate 21 transmits movement to the rotating arm 10 through the crawler wheel joint shaft 6 arranged on the support plate, the rotating arm 10 transmits movement to the support 11 through the support leg joint shaft 14, and the support 11 is connected with the machine body 5, so that the movement is finally transmitted to the machine body, and the machine body is driven to complete forward movement and backward movement.
