Description

Technical Field

[0001] This application belongs to the field of mechanical transfer systems in the design technology of ship equipment in the shipbuilding industry, and relates to a horizontal transfer device and method suitable for heavy tracked vehicles. Background Art

[0002] During the use of heavy tracked vehicles, when their power systems or running systems fail, the vehicles usually lose their running ability. The existing fault handling methods mainly include two types: one is to repair the faulty vehicle in place, and the other is to use a towing vehicle to tow the faulty vehicle away from the fault location for repair. However, in some special cases, the above methods may not be able to effectively solve the problem. For example, when the towing vehicle cannot arrive in time, and the road or passage conditions restrict subsequent vehicles from bypassing, the presence of the faulty vehicle will directly block the traffic and affect the normal passage of subsequent vehicles.

[0003] Typical road conditions include: 1. Road width limitation: Some roads or passages only allow single vehicles to pass in one direction, and subsequent vehicles cannot bypass; 2. Bridge structure limitation: On special facilities such as bridges, due to the bridge width limitation, vehicles cannot drive out of the area outside the road width range; at the same time, the bearing capacity limitation of the bridge may cause it unable to bear the concentrated towing load of the towing vehicle on the faulty vehicle.

[0004] In these scenarios, the existing towing or in-place repair methods have obvious limitations. The lack of a towing vehicle or the road conditions restrictions make it impossible to move the faulty vehicle away in time, resulting in subsequent vehicles being unable to continue passing. Therefore, there is an urgent need for an operating device that can horizontally transfer the faulty vehicle and park it on the side in a short time, so that subsequent vehicles can resume passing. After the towing vehicle arrives, then tow the faulty vehicle away from the fault location, or perform in-place repair after all subsequent vehicles have completely passed.

[0005] When dealing with faults of heavy tracked vehicles, the existing technologies lack a solution that can quickly and flexibly respond to special road conditions, especially when the towing vehicle cannot arrive in time or the road conditions are restricted. Therefore, developing an operating device suitable for such scenarios has important practical significance. Summary of the Invention

[0006] The object of the present invention is to provide a horizontal transfer device and method suitable for heavy tracked vehicles, so as to solve the problem that when a heavy tracked vehicle breaks down on a one-way traffic section, it is necessary to temporarily transfer the faulty vehicle to the side of the road in a short time to keep the road unobstructed.

[0007] To achieve the above object, the technical solution of the present invention provides a horizontal displacement device applicable to heavy crawler vehicles, including a horizontal displacement device and a mobile hydraulic pump station.

[0013] Preferably, a first traction ear plate and a second traction ear plate are respectively provided at the front end and the rear end of the chassis structure for connecting a traction pin shaft to connect the horizontal displacement device to the vehicle.

[0019] Preferably, during the movement process, manually adjust the swing arm to adjust the release or retraction of the traveling wheels in the traveling wheel assembly to meet different operation requirements.

[0020] Preferably, when lifting the vehicle, a triangular support structure is formed by the lifting point and the rear two-track sides to ensure the stability and safety of the vehicle.

[0021] In summary, the present invention includes the following beneficial technical effects:

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] The embodiments of the present invention disclose a device and its operation method suitable for horizontal lateral displacement of heavy tracked vehicles. The device and method aim to solve the problem that when a heavy tracked vehicle breaks down on a one-way traffic section, the faulty vehicle needs to be temporarily displaced to the side of the road in a short time to keep the road unobstructed. The device of the present invention has a simple structure, an easy-to-master operation process, and low requirements for operators, and is suitable for rapid training and application.

[0043] The horizontal displacement device of the present invention includes two groups of horizontal displacement devices and two groups of mobile hydraulic pumping stations. The horizontal displacement device is composed of key components such as a horizontal oil cylinder 5, a lifting oil cylinder 6, an underframe structure 2, a sliding frame 7, and a traveling wheel assembly 4.

[0044] The underframe structure 2 is the basic structure of the entire horizontal displacement device and provides an installation and support platform for other components. C-shaped grooves are provided on both sides of the top of the underframe structure 2. The C-shaped groove is a C-shaped metal groove and serves as a slide rail for the sliding frame 7 to run. The sliding frame 7 is installed between the C-shaped grooves on both sides of the underframe structure 2 and can slide along the C-shaped groove.

[0045] A first oil cylinder connection ear plate 22 is provided on the underframe structure 2, and a second oil cylinder connection ear plate 8 is provided on the sliding frame 7. Both ends of the horizontal oil cylinder 5 are respectively connected to the first oil cylinder connection ear plate 22 and the second oil cylinder connection ear plate 8 through the oil cylinder pin shaft 3. When the horizontal oil cylinder 5 makes a telescopic movement, the sliding frame 7 slides along the slide rail (C-shaped groove). The lifting oil cylinder 6 is installed on the sliding frame 7, and its lifting movement is controlled by a mobile hydraulic pumping station.

[0046] There are 4 sets of walking wheel assemblies 4 arranged on the outside of the chassis structure 2. The walking wheel assembly 4 includes a walking wheel 41, a roller pin shaft 42, a swing arm 43, a positioning pin shaft 44, a swing arm handle 45 and a swing arm rotating shaft 46. The 4 swing arms 43 are symmetrically arranged on both sides of the chassis structure 2 and are arranged on the chassis structure 2 through the swing arm rotating shaft 46. The swing arm 43 can rotate along the swing arm rotating shaft 46. The walking wheel 41 is the core component of the walking wheel assembly 4. It is connected to the swing arm 43 through the roller pin shaft 42 and allows the walking wheel 41 to rotate. It can contact the ground to enable the equipment to move; the walking wheel 41 can be released or retracted by manually adjusting the swing arm 43. During operation, the walking wheel 41 can be adjusted to be lifted, and then the chassis structure 2 can be lowered to the ground.

[0047] The swing arm handle 45 is used to operate the swing arm 43 to adjust the release and retraction of the walking wheel 41. There is a positioning ear plate on the swing arm 43, and there is a plate-like structure corresponding to the positioning ear plate on the chassis structure 2. The plate-like structure is provided with through holes; the positioning pin shaft 44 can pass through the positioning ear plate and the plate-like structure to lock the position of the swing arm 43.

[0048] When the walking wheel 41 is released, the horizontal displacement device enters the walking mode and can be pulled by an external force to move; when the walking wheel 41 is retracted, the chassis structure 2 descends to the ground, and the jacking oil cylinder 6 can bear the external pressure load.

[0049] The traction pin shaft 1 is a component connecting the horizontal displacement device and the vehicle; the traction ear plate one 21 and the traction ear plate two 24 are respectively installed at the front end and the rear end of the chassis structure 2, providing connection points for the traction pin shaft 1 to ensure its firm installation on the chassis structure 2. The function of the traction pin shaft 1 is to connect the horizontal displacement device and the vehicle so as to transmit the traction force during the displacement process.

[0050] The mobile hydraulic pump station consists of a set of hydraulic pump stations and a self-propelled trolley 9, and is used to provide a power source for the horizontal displacement device. The self-propelled trolley 9 is a commercially available component, powered by a battery, has the function of self-propelling, and serves as the power source of the hydraulic pump station. The hydraulic pump station is installed on the self-propelled trolley 9 and consists of a hydraulic oil tank 10, a motor pump unit 11 and a control valve group 12. There are two sets of control valve groups 12. One set is used to control the telescopic action of the horizontal oil cylinder 5 of the horizontal displacement device, and the other set is used to control the telescopic action of the jacking oil cylinder 6.

[0051] The horizontal displacement device can be connected to the mobile hydraulic pump station. By operating the mobile hydraulic pump station, the horizontal oil cylinder 5 is driven to drive the sliding frame 7 to move in the slide rail, and the lifting and lowering action of the jacking oil cylinder 6 is controlled. By operating the swing arm handle 45, the release and retraction of the walking wheel 41 in the walking wheel assembly 4 can be adjusted, and the positioning pin shaft 44 can be set in the pin hole on the positioning ear plate on the side of the chassis 23 to lock the position. The mobile hydraulic pump station can be connected to the horizontal displacement device through a quick connector, and the horizontal displacement device can be towed to move with the power of the mobile hydraulic pump station.

[0052] The horizontal displacement operation requires at least three operators, including two operators and one commander and safety officer. The specific operation process of the horizontal displacement device is as follows:

[0053] 1. Transport the horizontal displacement device to the faulty vehicle;

[0054] 2. Connect the two horizontal displacement devices to the pump station through quick connectors, and manually push the horizontal displacement devices to the midline position under the vehicle, one in the front and one in the back;

[0055] 3. Start the hydraulic pump station, operate the No. 1 horizontal displacement device (assumed to be in the front) to lift the front part of the vehicle, and then operate the horizontal oil cylinder 5 of the No. 1 horizontal displacement device to drive the vehicle to move horizontally in a triangle with the No. 1 jacking point and the two rear crawlers (the rotation center is near the center of the two rear grounding wheels on the midline), and gradually retract the jacking oil cylinder 6 and the horizontal oil cylinder 5;

[0056] 4. Operate the No. 2 horizontal displacement device (in the back) in the same way;

[0057] 5. Manually push the horizontal displacement device to the target displacement direction through the chain or aluminum alloy round tube configured on the horizontal displacement device until the jacking oil cylinder 6 is basically aligned with the vehicle midline;

[0058] 6. Repeat the actions of the No. 1 and No. 2 horizontal displacement devices above;

[0059] 7. The No. 1 and No. 2 horizontal displacement devices operate alternately, which can achieve the purpose of translating the faulty vehicle to one side of the main road;

[0060] 8. Subsequent vehicles can bypass on one side of the faulty vehicle and continue to move forward.

[0061] Through the above equipment and operation method, the present invention can efficiently and safely complete the horizontal lateral displacement operation of heavy crawler vehicles, ensuring smooth traffic. The present invention uses two groups of horizontal displacement devices to alternately perform the horizontal displacement operation of faulty vehicles. The horizontal displacement device realizes the horizontal displacement function of the faulty vehicle through the combined alternate actions of the horizontal oil cylinder 5 and the jacking oil cylinder 6. The adjustment mechanism composed of the walking wheel assembly 4 and the positioning ear plate can manually adjust the release and retraction of the walking wheel 41 to adapt to different operation requirements.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
