Abstract

The invention discloses a hydraulic walking device and a control method thereof, belongs to the technical field of ship transportation, and solves the technical problems that the transportation distance of an existing large hydraulic oil cylinder is limited, and the large hydraulic oil cylinder is complex in manufacturing process, large in weight and high in use cost. The hydraulic walking device comprises a guide rail, a hydraulic mechanism, a first positioning mechanism and a second positioning mechanism, and a plurality of positioning parts are arranged on the guide rail at intervals; the hydraulic mechanism comprises a first oil cylinder arranged on the guide rail in a sliding mode and a first piston rod which is arranged in the first oil cylinder and can move back and forth in the axial direction of the first oil cylinder; and the first positioning mechanism and the second positioning mechanism are respectively arranged at the two ends of the hydraulic mechanism, the first positioning mechanism is arranged at a fixed end of the first oil cylinder, the second positioning mechanism is arranged at the end of the first piston rod of the first oil cylinder, and the first positioning mechanism and the second positioning mechanism are both connected with the positioning parts in a switchable mode. According to the hydraulic walking device provided by the invention, the weight and various costs of ship transportation are reduced, and the transportation distance is greatly increased.

Example Embodiment

[0050] Example 2
[0051] The present embodiment discloses a hydraulic control method of a traveling apparatus, the hydraulic traveling apparatus applied in Example 1, with reference to Figure 5 , Includes the following steps:
[0052] Step 1: The first positioning mechanism 400 and the connecting portion corresponding to the positioning position, the second positioning mechanism 500 from the position corresponding to the positioning portion.
[0053] Step 2: the first piston rod of the hydraulic mechanism extends 202,200 until the second positioning mechanism 500 is positioned aligned with a portion of the hydraulic mechanism 200 maintains the current state.
[0054] Step 3: the positioning portion 500 and a second position corresponding to positioning means connected to the first positioning mechanism 400 from the position corresponding to the positioning portion.
[0055] Step 4: the first piston rod 202 of the hydraulic mechanism 200 is contracted, while the first cylinder 201 is moved along the guide rail 100 until locating the first portion 400 aligned with a positioning mechanism, the hydraulic mechanism 200 maintains the current state, i.e., the traveling device hydraulic complete a walking operation.
[0056] Step 5: Repeat the above steps, the first cylinder 201 traveling along the rails 100 of the long distance.
[0057] When will be appreciated, when the hydraulic traveling device traveling to the ends of the guide rail 100, the need to return to the first end rail 100, it can be appreciated, comprising the steps of:
[0058] Step 6: the positioning portion 500 and a second position corresponding to the connector positioning mechanism, the positioning mechanism 400 from the first positioning portion corresponding position:
[0059] Step 7: the first piston rod of the hydraulic mechanism extends 202,200 until the second hydraulic mechanism 200: positioning means at one end of a positioning portion 300 are aligned, the hydraulic mechanism 200 maintains the current state.
[0060] Step 8: The first positioning mechanism 400 and the connecting portion corresponding to the positioning position, the second positioning mechanism 500 from the position corresponding to the positioning portion.
[0061] Step 9: The first piston rod 202 of the hydraulic mechanism 200 is contracted, while the first cylinder 201 moves along the guide rail 100, a second positioning mechanism 500 until a positioning portion aligned with the hydraulic mechanism 200 maintains the current state, i.e., the traveling device hydraulic complete a walking operation.
[0062] Step 10: Repeat the above steps until the first cylinder 201 is reset to the head end rail 100.
[0063] By the above method of controlling the hydraulic traveling apparatus may be reciprocated on the guide rail 100, the hydraulic traveling device capable of traveling long distances, in a case where the carrying capacity to ensure a substantial increase of the transport distance of the hydraulic traveling apparatus, safe and convenient.
