Description

The utility model relates to equipment for floating facilities, in particular to devices for launching and lifting boats, boats, etc. directly from the vehicle to the water and vice versa.

In most cases, floating equipment is transported to the water using trailers, which are equipped with either lodges (wooden guides) or a roller system.

For example, a solution is known for a boat trailer (US patent, published 11/27/1973), which contains longitudinal cradles for holding the boat during transportation and a receiving roller with a central recess located at the end of the boat and designed to launch the boat into the water and facilitate lifting it.

The disadvantage of this solution is the insufficient sliding of the boat along the longitudinal cradles during its launching and ascent, which leads to the need to use additional systems for loading and unloading, in which several people can sometimes be involved, which makes the use of the considered design laborious and inconvenient.

Also known is a device for loading boats (Australian patent No. 2018202017, published 04/26/2018), containing a frame of guides, receiving roller assemblies at the end of the boat, connected to a hydraulic drive motor and a hydraulic pump, rollers in the central part of the device. The receiving roller assemblies provide a retracting effect when loading the boat, and the rollers in the central part serve to further slip the bottom of the boat onto the vehicle.

However, the disadvantage of this solution is the constant contact of the rollers with the bottom of the boat during the entire period of transportation, which leads to the appearance of dents, scratches, cracks and other defects. This not only spoils the appearance of the floating vehicle, but also leads to a violation of the protective layer of the bottom of the boat, which, in contact with water, accelerates the corrosion process and, as a result, reduces the life of the boat.

A device for loading and unloading a floating vehicle is known (RF patent No. 80429, published on February 10, 2009), taken as the closest analogue to the claimed solution, containing a frame on which two pairs of longitudinal guides are installed, between each pair of which support rollers are installed, the axes of which, through pivotally connected levers, are connected to the longitudinal rods, which are connected to the transverse rods interacting with the screw mechanism. When loading and unloading a floating device with the handle of the screw mechanism, the support rollers are lifted up above the surface of the guides through the transverse rods, longitudinal rods and levers. The boat is rolled onto the vehicle (trailer) along the support rollers. For the subsequent transportation of the floating device, by rotating the handle of the screw mechanism in the opposite direction, the support rollers are lowered down, that is, the boat is placed on the rails, which are covered with carpet flooring.

This design of the device allows you to combine the two solutions discussed above. Due to the presence of support rollers, which can be raised above the surface of the cradle, the sliding friction force is excluded, which makes it possible to easily ensure the loading and unloading of the floating vehicle. Due to the presence of lodgements covered with carpet flooring, a reliable fixation of the boat during transportation is ensured.

However, for raising and lowering the rollers, a screw mechanism is used, which requires the application of significant forces from the user, which is not always convenient.

The technical problem of the present utility model is the creation of a device for loading and unloading a floating vehicle, expanding the range of similar products on the market, which also simplifies the process of lifting and lowering the support rollers.

The technical result of the utility model is the implementation of the specified purpose.

The technical result is achieved when using a device for loading and unloading a floating vehicle containing a frame with two longitudinal cradles, support rollers located between parts of each of the cradles, while the axes of the support rollers are connected through levers to longitudinal rods, which in turn are connected to a hydraulic cylinder.

In a particular case, the hydraulic cylinder is connected to the hydraulic pump, which creates the pressure of the hydraulic fluid, through the laying of a hydraulic route along the frame of the loading and unloading device.

The use of such a hydraulic system makes it possible, without much effort, due to several clicks, even with one hand, to quickly and conveniently raise the support rollers above the surface of the guides (cradles) or lower them.

The device for loading and unloading a floating vehicle contains a frame 1 on which two longitudinal cradles 2 are installed, covered with a flooring made of a material with a high coefficient of friction, for example, a carpet. Support rollers 3 are installed between the parts of each of the cradles 2, made of elastic rubberized material, excluding spontaneous slipping of the floating vehicle. Support rollers 3 have an axis of rotation 4. They are connected to levers 5, which are mounted on a longitudinal rod 6 (Fig. 1, 2).

The longitudinal rods are connected to the hydraulic cylinder 7 (Fig. 3).

Receiving rollers 8 (Fig. 1) are installed on the end part of the lodgements.

The lever 5 for lifting and lowering the rollers is a plate 9, which is welded to the same plate through one slide sleeve, and one end of which contains a lever roller for lifting and lowering 10, having an axis of rotation 11. Also, the lever 5 has an axis 12 for fixing the sleeve sliding, connecting it to the longitudinal rod 6 (Fig. 4).

The longitudinal rod 6 is a profile pipe 13, which at its ends has a bracket 14 for attaching a hydraulic cylinder 7, a hole 15 for installing the above bushing and a lever 5 for lifting and lowering the support rollers 3. The ends of the profile pipe 13 are sealed with plugs (Fig. 5).

The hydraulic cylinder 7 is connected via a hydraulic line (Fig. 6) to a hydraulic pump mounted on the drawbar of the trailer (not shown).

The claimed device works as follows.

In the initial position, the longitudinal thrust is set aside to the limit so that the support rollers 3 are lowered and located between the parts of the lodgments 2 (Fig. 7a).

The user then presses down on the handle of the hydraulic pump with a minimum of force. The pressure of the pumped fluid is transmitted along the hydraulic line to the hydraulic cylinders. There is a displacement in the opposite direction of the longitudinal rod 6, which drives the levers 5, which in turn raise the support rollers 3 above the surface of the cradle 2 (Fig. 7b). After that, it becomes possible to lower the floating vehicle or lift it onto the vehicle.

When the loading of the floating vehicle is completed, the fluid pressure is released in the hydraulic pump, which leads to the displacement of the longitudinal thrust 6 and levers 5 and then to the lowering of the support rollers 3 and their return to their original position. The loaded vessel, due to its weight, also makes it possible to additionally influence the lowering support rollers 3 and speed up this process.

The inventive design makes it possible to reduce the labor intensity of raising and lowering the support rollers, which makes the use of the device for loading and unloading simpler and more convenient.
