Description

Technical Field

[0001] The utility model relates to the technical field of boat transportation, in particular to a vehicle-mounted assault boat folding and unfolding device with a sliding bracket. Background Art

[0002] During the use of assault boats, during land transportation, return to the warehouse, storage and maintenance, transport vehicles are needed to fold and deploy the boats on the shore. During the folding and deploying process, how to stabilize and protect the boats is a difficult problem.

[0003] Currently, when recovering assault boats, multiple rows of V-shaped support wheels are usually set on the frame. When recovering the boat, the vehicle is first poured into the water to a certain depth to meet the requirements for the boat to float. Then the boat is driven onto the frame and towed with the cooperation of the towing mechanism. However, when the boat is driven onto the frame, it cannot be guaranteed that the boat body is aligned with the frame, resulting in the boat body tilting during the towing process, affecting the recovery.

[0004] Therefore, it is necessary to propose a vehicle-mounted assault boat retracting and deploying device with a sliding bracket to solve the above problems. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a vehicle-mounted assault boat retracting and deploying device with a sliding bracket, which has the following beneficial effects:

[0018] The vehicle-mounted assault boat retraction and deployment device with a sliding bracket is provided with a bracket and an outer roller. The bracket is used to limit and guide the boat so that the boat body is aligned with the vehicle frame.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-5As shown, a vehicle-mounted assault boat folding and launching device with a sliding bracket includes a frame 3, a bracket 2 is slidably connected to the frame 3 along its length, a traction winch 4 for towing the bracket 2 to slide is fixedly connected to the front end of the frame 3, and a support member 9 adapted to the front end of the boat 1 is fixedly connected to the bracket 2; multiple groups of outer rollers 5 are symmetrically arranged on both sides of the bracket 2, and the wheel surfaces of the outer rollers 5 are in contact with the side walls of the boat 1 and are rotatably connected to the frame 3.

[0027] By providing the bracket 2, when the boat 1 needs to be folded up, the front end of the boat 1 is driven onto the bracket 2, and then the bracket 2 and the boat 1 are pulled by the traction winch 4 to slide toward the frame 3. Under the action of the bracket 2, the boat 1 can be guided so that the boat body of the boat 1 is aligned with the frame 3. As the buoyancy decreases, the boat body is supported by the outer roller 5 and slides and is recovered until it is recovered in place.

[0028] In some embodiments, a limiting groove 6 is fixedly connected to the frame 3 along its length, and the bracket 2 is slidably connected to the limiting groove 6 via a slide bar 8. Specifically, the limiting groove 6 is provided on both sides of the bracket 2. By providing the limiting groove 6 on both sides of the bracket 2, the bracket 2 is restrained and prevented from shifting during sliding. Preferably, the limiting groove 6 has a C-shaped cross-section, and the slide bar 8 slides within the C-shaped groove. Blocks are fixed at both ends of the limiting groove 6 to prevent the bracket 2 from dislodging from the frame 3.

[0029] In order to reduce the friction between the bracket 2 and the frame 3, the frame 3 is rotatably connected with an inner roller 7 for supporting the bracket 2. Specifically, the layout height of the inner roller 7 is less than the layout height of the outer roller 5.

[0030] In order to prevent the outer roller 5 from damaging the hull of the boat 1 , a rubber layer is provided on the outer side of the outer roller 5 .

[0031] To facilitate synchronous towing of boat 1 and bracket 2, a towing plate 10 is fixedly connected to the front end of boat 1, and a connecting rope 12 is provided at the front end of bracket 2. During connection, bracket 2 is connected to towing plate 10 via connecting rope 12, and a towing rope 11 on towing winch 4 is connected to towing plate 10. During towing, towing rope 11 pulls boat 1 toward frame 3, and boat 1 acts on bracket 2 through support member 9 and connecting rope 12, causing bracket 2 to move synchronously.

[0032] In order to prevent the boat 1 from colliding with the frame 3 due to inertia, the front end of the frame 3 is fixedly connected to an elastic baffle 13 that is adapted to the front end of the boat 1 .

[0033] Working principle: When recovering the boat 1, first pour the vehicle into the water to a certain depth to meet the requirement for the boat 1 to float. At this time, the traction rope 11 of the traction winch 4 is connected to the connecting rope 12 at the front end of the bracket 2. The traction winch 4 is controlled to lower the bracket 2 to the extreme position at the end of the frame 3. Then, the boat 1 is driven above the bracket 2. The traction rope 11 of the traction winch 4 and the connecting rope 12 at the front end of the bracket 2 are connected to the traction plate 10 at the front end of the boat 1. The traction winch 4 is started to pull the boat 1, and the boat 1 pulls the bracket 2 through the connecting rope 12 to recover the boat at the same time.

[0034] After a period of recovery, as the buoyancy decreases, the boat 1 falls onto the bracket 2 and is supported by the support member 9 on the bracket 2; the boat 1 continues to recover, and after the buoyancy further decreases, the rear of the boat 1 contacts the outer roller 5 on the frame 3 and continues to roll on the outer roller 5 for recovery;

[0035] At the final stage of recovery, the buoyancy is very small, and the vehicle is mainly supported by the outer rollers 5 on the frame 3 and continues to roll until it is recovered in place. The unloading process is the opposite.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
