Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft technology, and in particular to an aircraft traction device. Background Technology
[0002] Underwater vehicles are playing an increasingly important role in fields such as marine resource development, marine scientific research, and underwater engineering construction. For example, in deep-sea mineral exploration, underwater vehicles are needed to go deep into the seabed to collect samples. In marine ecological monitoring, they can detect marine environmental parameters at different depths. However, the recovery, deployment, and operation of underwater vehicles face many challenges. In the deployment phase, complex sea conditions such as strong currents and large waves can make it difficult for the vehicle to accurately locate the receiving ship or deployment point, which will affect the normal operation of the vehicle in the future.
[0003] Existing technologies typically involve using an iron rod to press the vehicle into a designated position in the water, or using a steel cable wound around a winch to pull the vehicle to a designated position in the water, thus enabling the receiving ship's robot to capture the vehicle. However, these two methods cannot flexibly adjust the position of the navigator, have poor maneuverability, and cannot achieve precise capture of the vehicle by the receiving ship. Utility Model Content
[0004] The purpose of this invention is to provide a vehicle towing device, which consists of a gripper holding the vehicle and the gripper being fixed to a movable device. The movable device slides on a vertical support, and the vertical support is bolted to a horizontal support. Based on the horizontal straight-line distance between the receiving vessel and the dock, the position of the vertical support on the horizontal support is adjusted on the shore. Based on the vertical distance between the receiving vessel and the vehicle, the position of the movable device on the vertical support is adjusted, thereby sending the vehicle to the designated location and enabling the receiving vessel to accurately capture the vehicle.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tractor for a vessel, comprising a transverse support for fixing the hull, a vertical support connected to the transverse support, a movable device that can slide up and down along the vertical support, and a gripping component fixedly connected to the movable device.
[0006] By adopting the above technical solution, the horizontal support and the vertical support are connected, which facilitates the horizontal movement of the vertical support on the horizontal support. At the same time, the moving device can slide on the vertical support, thereby realizing the horizontal and vertical movement of the gripper.
[0007] The present invention is further configured as follows: the horizontal support includes a horizontal brace and a vertical chord, which are vertically and fixedly connected; the vertical support includes a chord assembly and a slide rail, which are fixedly connected; the moving device includes a sliding support, which is slidably engaged with the slide rail via a sliding sleeve; the gripping component is a claw, which is fixedly disposed at the end of the sliding support, and a camera for observing underwater conditions is fixedly disposed on the claw.
[0008] By adopting the above technical solution, the gripper is used to hold the vehicle and bring it to the designated position. A camera is installed on the gripper and the camera is capable of working at least 6m below the water surface. The monitoring video is transmitted to the camera host screen through the signal line, thereby monitoring the underwater docking of the vehicle.
[0009] A further feature of this invention is that a steel truss, which serves to reinforce and support the structure, is fixedly connected at the connection between the transverse and longitudinal chords, and bolt holes are provided on the lower surface of the longitudinal chord.
[0010] By adopting the above technical solution, the steel truss enhances the stability of the transverse support. Bolt holes are provided on the lower surface of the longitudinal chord to facilitate bolting and connection with the mounting block on the top of the vertical support. The bolting connection of the transverse and vertical supports is carried out on the shore. First, the distance between the ship and the dock is measured to determine the position of the vertical support of the tugboat towing frame on the transverse support. After the bolts of the vertical and transverse supports are tightened, the tugboat towing frame is then placed in the water.
[0011] A further feature of this invention is that the chord assembly includes an upper chord assembly and a lower chord assembly, which are arranged in parallel at both ends of the slide. A support rod for supporting the transverse bracket is fixedly connected to the upper part of the slide. An installation block is fixedly connected to the top of the support rod, and a bolt is provided on the top surface of the installation block. The bolt is fixedly connected to the bolt hole.
[0012] By adopting the above technical solution, the upper chord assembly and the lower chord assembly are arranged in parallel at both ends of the slide, forming a stable frame structure, which provides basic support and stability for the entire device. The upper part of the slide is connected to the mounting block through the support rod. The support rod can effectively transfer the force borne by the slide to the mounting block, further enhancing the connection strength between the slide and the upper structure, so that the entire structure has better stability in the vertical direction.
[0013] The vertical support is installed below the horizontal support and is fixed with bolts. The bolt holes are spaced 300mm apart at the connection between the horizontal and vertical supports, which allows the vertical support to move laterally on the horizontal support. The vertical support can be precisely fixed in a designated position on the horizontal support. The bolt connection also has the advantage of easy disassembly. When the vehicle's towing device is not working in the water, the horizontal and vertical supports can be separated and placed separately to avoid occupying too much ground space.
[0014] A further feature of this invention is that the chuck has a curvature, and a rubber pad is provided in the concave part of the chuck.
[0015] By adopting the above technical solution, the claw has an arc shape to form a good match with the vehicle, and a rubber pad is provided inside the claw to increase the friction between the claw and the vehicle, thus preventing the vehicle from falling off during movement.
[0016] The present invention is further configured as follows: the upper chord assembly includes a first upper chord and a first lower chord, which are arranged in parallel. Both ends of the first upper chord and the first lower chord are fixedly connected to the slide rail. A first web member for support and reinforcement is fixedly connected between the first upper chord and the first lower chord. The structure of the lower chord assembly is the same as that of the upper chord assembly. A fixed column is provided between the first upper chord and the cross brace. A motor is fixedly connected to the fixed column. A sprocket shaft passes through the motor. The sprocket shaft is connected to the motor shaft. An upper sprocket is provided on the sprocket shaft. The sprocket shaft is keyed to the upper sprocket. A lower sprocket is provided at the lower chord assembly. The upper and lower sprockets are arranged longitudinally and are connected by chain drive. A middle sprocket is fixedly provided on the sliding bracket. The middle sprocket is located between the upper and lower sprockets and is arranged vertically and is connected to the upper and lower sprockets by chain drive.
[0017] By adopting the above technical solution, the upper chord assembly, through the combination of the first upper chord, the first lower chord, and the first web member, forms a stable structure that can effectively withstand loads from above or other directions. The lower chord assembly has the same structure, further enhancing the stability of the overall structure. This allows the entire device to maintain its shape under various working conditions and is not easily deformed. After the motor starts, it drives the sprocket to rotate, which in turn drives the chain to rotate. As the chain rotates, the sliding bracket also moves up and down, eventually driving the pawl to move together, thereby realizing the vertical movement of the vehicle. To facilitate the control of the motor's start and stop and the vehicle's upward or downward movement, a handheld wired remote control with a cable length of 20m is provided, which can be moved to the work site with the operator.
[0018] A further feature of this invention is that position sensors are attached to both the upper and lower parts of the slide.
[0019] By adopting the above technical solution, when the moving device reaches the upper limit and touches the position sensor, the motor automatically stops; when the moving device reaches the lower limit and touches the position sensor, the motor automatically stops, ensuring that the sliding bracket moves within the set vertical range.
[0020] The beneficial effects of this utility model are:
[0021] 1. The vehicle towing device of this application can adjust the position of the vertical support of the vehicle towing frame on the horizontal support according to the position of the receiving ship at the distance from the dock measured on the shore. After the vehicle towing frame is put into the water, the moving device can be driven up and down by the chain, thereby changing the vertical position of the chuck and realizing the precise deployment of the vehicle.
[0022] 2. The vertical support is installed below the horizontal support and fixed with bolts. The bolt hole spacing at the connection between the horizontal and vertical supports is 300mm, which allows the vertical support to move laterally on the horizontal support. It can accurately fix the vertical support in a designated position on the horizontal support. The bolt connection has the advantage of easy disassembly. When the vehicle's towing device is not working in the water, the horizontal and vertical supports can be separated and placed to avoid occupying too much ground space.
[0023] 3. A camera is installed on the gripper, and the camera is capable of operating at a depth of at least 6 meters below the water surface. The monitoring video is transmitted to the camera host screen via a signal cable to monitor the underwater docking of the vehicle.
[0024] 4. The claws are curved to ensure a good fit with the aircraft, and rubber pads are installed inside the claws to increase friction between the claws and the aircraft, preventing the aircraft from falling off during clamping.
[0025] 5. Position sensors are engaged at both the upper and lower parts of the slide. When the moving device reaches the upper limit and touches the position sensor, the motor automatically stops. When the moving device reaches the lower limit and touches the position sensor, the motor automatically stops, ensuring that the sliding support moves within the set vertical range.
