Description

HOIST FASTENING DEVICE
The invention relates to a hoist fastening device according to the preamble of claim 1. The invention particularly relates to the fastening devices of hoists employed in connection with all-terrain vehicles, ski-slope preparation vehicles or equivalents. Using hoists, such as e.g. passenger hoists, in irregular terrain is problematic. Conventional passenger hoists have to be sufficiently supported before hoisting, which incurs considerable problems or is totally impossible in steep terrain conditions. Transporting conventional hoists to the hoisting place is also difficult, particularly in winter conditions. At ski resorts, various hoisting tasks related to the maintenance and construction of ski lifts and other ski-slope devices have to be performed. In connection with malfunctions of chair and gondola lifts, passengers trapped in the lifts must be able to exit within reasonable time. At the moment, local rescue units have no suitable hoisting equipment for rescuing the passengers from chairs or gondolas sometimes stopped very high.
The present invention provides a hoist fastening device by means of which a hoist is fastened to an all-terrain vehicle, such as a ski-slope preparation vehicle. The hoist fastening device consists of a hoisting framework which includes means for vehicle fastening. The hoisting framework is fastened e.g. to the hoisting devices of ski- slope preparation vehicles with a three-point fastening which includes a usually upper crosswise fastening pin and lower fastening cones the parties of which are locked together with a tensioning means. The hoisting framework is fastened with a substantially shelf-like body which again includes means for fastening a hoisting boom. In connection with the hoisting framework, there are adjustable support feet by means of which the hoist is supported on the base in connection with hoisting. Typically, there are two support feet at the rear part of the body (rear support feet) and one support foot at the front part of the body or it is directed forward in the drive direction of the vehicle (front support foot). The support feet are provided with safety devices which ensure the position of the support feet and tight support during hoisting.
The hoist fastening device and the actual hoist form a device combination which can be relatively quickly fastened to a vehicle and equivalently detached from the vehicle. The combination detached from the vehicle is supported into the vertical position by the adjustable support feet in connection with the fastening device. Power required by the hoist is obtained from a combustion engine or an electric motor in connection with it. The electric motor is driven by batteries or alternatively electric power is conveyed with conductors from the vehicle.
The invention enables the quick fastening of the hoisting boom to the vehicle. The invention eliminates disadvantages of prior art and provides a fastening device which is simple of its construction and inexpensive of its investment costs.
Said advantages are provided with the fastening device according to the invention which is characterised by what is presented in the claims.
Next, the invention will be described in detail by means of some advantageous embodiments and with reference to the enclosed drawings.
Fig. 1 schematically shows a side view of a hoist fastening device according to the invention fastened to a vehicle.
Fig. 2 shows an oblique top view of a hoist fastening device.
Fig. 3 shows an embodiment of a hoist in which a front support foot of the hoist is provided with a push arm.
Figs. 1-3 show a hoist fastening device 3 which includes means 3e and 3d for fastening to a vehicle 1 and rear support feet 3b and a front support foot 5, 3c for supporting the hoist during hoisting. In connection with the fastening device 3, there also are means 3g and 3f for fastening a hoisting boom 4a of a hoist 4. The fastening device 3 consists of a hoisting framework 3h which is fastened with an angularly bent body plate 3a2. The body plate 3a2 is supported by a box-like and triangular support structure 3a, 3al to form a shelf-like structure. In the bent body plate is arranged a fastening flange 3f to which the hoisting boom 4a can be fastened with the fastening means 3g. The hoisting framework 3h consists of a horizontal beam 3hl on the front surface of which are arranged fastening cones 3e of a three-point fastening. A substantially horizontal pin 3d included in a snap-in fastening is fitted to lugs 3dl . The lugs 3dl are fastened on the vertical surface of the body plate and they are supported by box-like beams 3h2 on both sides. The beams 3h2 are fastened both to the horizontal beam 3hl and the body plate 3a2. Into connection with the hoisting framework 3h and into connection with the triangular support structure 3al are arranged the adjustable rear support feet 3b. The rear support feet are arranged to move in their holder 3b 1 and are lockable with locking devices 3b2 which are e.g. pins, tensionable screws or equivalents. The front support foot 3c in connection with the triangular support structure 3a 1 is arranged to rotate around a joint 3c 1 and substantially within the triangular support structure 3a, 3al . In the embodiment shown in Fig. 3, the front support foot 5 in connection with the triangular support structure 3al is arranged to rotate around a joint 5d which joint is located within the triangular support structure 3a, 3al. The front support foot 5 consists of a first beam 5a which is slidingly fitted within a second beam 5c. The beams 5a and 5b are locked together with a locking element 5b. The position of the front support foot is adjusted with a push arm 5f or an equivalent adjusting element which is fastened from one end to the triangular support structure with a joint 5e and from the other end to the beam 5c with a joint 5g. The joints 5e and 5d are located within the triangular support structure 3a, 3al at a sufficient distance from each other. Then, locking the beams 5 a and 5b together creates a closing rod structure which enables the stability of the hoist during hoisting. In an advantageous embodiment, the joint 5d is substantially located at the rear part of the triangular support structure 3al and the joint 5e substantially at the front part of the support structure 3a 1. Then, the front support foot 5 is substantially directed forward and the angle of the front support foot in relation to the base is in the range of 40-60 degrees.
The combination formed by the vehicle 1, the hoist fastening device 3, the hoist 4 and the support feet 5, 3b operates in the following way. The fastening device 3 is connected to conventional connecting devices 2 of the vehicle which typically include actuators 2a and 2b and a fastening stand 2c controlled by these actuators. In a ski-slope preparation vehicle, the connection commonly occurs with a three- point fastening which includes usually lower fastening cones 2e and an upper substantially horizontal fastening slot 2d. The fastening slot 2d is first set to the horizontal pin 3d in the fastening device 3 and then the fastening cone 3e in the fastening device is fitted in the respective fastening cone 2e. The fastening cones 2e and 3e are tensioned together with tensioning means to provide a positive- locking three-point fastening.
The hoisting boom 4a of the hoist is fitted in the flange 3f with a respective flange 3fl in the boom and tensioned together with suitable fastening elements 3g, such as screws. The power required by the hoist is obtained from a combustion engine or an electric motor in connection with the hoist or alternatively from an energy source la of the vehicle with proper conductors (not shown in the figures). The hoist, e.g. passenger hoist, fastened to the vehicle can now be controlled with control devices in connection with the vehicle or the hoist. Before hoisting, the front support feet 3b and the rear support foot 5 are adjusted against the base and the correct position of the support feet is ensured by means of safety devices (not shown in the figures). During hoisting, the operation of the safety devices is arranged such that the support remains stable. The safety devices prevent the operation of the hoist in case the base buckles underneath the support feet. The boom 4a, 4b of the hoist and a hoisting cage 4c in the boom can be used in a normal way for various tasks within the limits allowed by the stability of the vehicle 1. The combination formed by the hoist 4 and the fastening device 3 can be detached from the snap-in fasteners and left standing in the vertical position supported by the support feet 3b, 5. In irregular terrain, the height of the support feet can be adjusted in their fastening device 3b 1 and locked in place with a locking device 3b2.
The figures and the description related to them are only intended to illustrate the present invention. Of their details, the hoist fastening device and its construction can vary within the scope of the enclosed claims and the inventive idea presented in the description of the invention. It is evident to those skilled in the art that the dimensions and technical arrangements of the invention can vary depending on their purpose of use. The embodiment of the invention can vary in accordance with conditions of use, customer requirements and production methods.
