Description

DESCRIPTION

Vehicle equipment fixing device

Equipment fixing device

Field of the Invention

The present invention relates to an equipment fixing device for loading equipment and heavy equipment according to the claims.

Background of the Invention

In many situations there is a need to move (transport) objects, goods, and the like between a first position and a second position. Several different types of machines and equipment have been developed for lifting and moving objects in order to transport these objects. For example, tractors, loading machines, forklifts, and various other types of machinery and equipment have been developed.

One problem in moving (transporting) objects, goods, and the like is that objects can vary greatly in type, which involves using different loading devices to move objects. Different types of objects and goods have led to the development of various and different devices with different characteristics such as forks, ladles and the like. To facilitate the exchange of different loading devices, heavy equipment and vehicles are equipped with holding brackets. Diverse and different variants of fixing supports have been developed such as the so-called «BM-bracket».

Another problem associated with freight transport is that it is often difficult to move long goods. It is especially difficult to move elongated goods if the transport vehicle fixing bracket lifts elongated goods in the transverse direction relative to the normal direction of the vehicles in motion. This can make the movement of goods with the transport vehicle within an industrial area quite difficult, as well as virtually impossible to move the goods safely along busy roads and the like. An additional problem associated with the movement of goods is that it can often be difficult to reach the goods and / or lift the goods because the goods are placed in an inaccessible location. During the handling of goods and the like, it may similarly be difficult to place the goods on the basis of the goods or the like that have already been placed.

One problem with the design of clamping brackets that includes pivot shafts is that there is clearance in the pivot shaft bearings. This is especially common if the bearings are exposed to excessive force and frequent use. Examples of designs exposed to heavy loads are designs such as that of the present invention and the designs mentioned in the prior art, where relatively long lifting arms create powerful bearing stresses on the pivot shafts. There is a need for designs where the clearance in bearing designs can be reduced in relation to the wear and tear of these bearings.

Another problem with known designs is that they apply tension to the bearings even when the design has itself folded (retracted). These designs create wear and tear on the bearings, causing the bearings to overstretch. There is a need for a design that significantly reduces the stress on the bearings when the design is in the extended position and is not, therefore, in use.

Prior art

A variant of a forklift clamping device is described in SE371994 also published as GB 1335879 A. This document describes the preamble of claim 1. The design consists of a first assembly (frame assembly) which is pivotally arranged relative to a second set (frame set). The first set is suitable for connection to a vehicle mounting bracket. The second set is pivotally arranged relative to the first set. The design according to its description further includes a third assembly (frame assembly) which is pivotally arranged relative to the second assembly. The design according to its description differs significantly from the design according to the present invention.

Document NL1300785 describes a variant of a device for handling loads with a forklift.

The device according to its description consists of at least a first set, which through a first vertical rotary axis is pivotably arranged in relation to a second set which through a second vertical rotary axis is pivotally arranged in relation to the third set. The design of the device differs significantly from the design according to the present invention. For example, the device according to NL1300785 is limited to use in forklift truck applications.

The device according to NL1300785 even has the problem that it cannot be easily transferred from one vehicle to another vehicle. Furthermore, it is not possible, correspondingly, to switch between different types of equipment with a design according to document NL1300785. A further problem with the device according to document NL1300785 is that the bearings of the rotary axes of the design still undergo stress when they are in the retracted position. To keep the bearings safe, they are overstretched. There may be slack in the design rotary axes after long use.

Purpose of the invention

The main purpose of the present invention is to create an improved equipment fixing device (fixing bracket) that solves or minimizes at least one of the aforementioned problems. This purpose is achieved with an equipment fixing device (fixing bracket) according to the claims.

Preferably, the equipment fixing device is connected to a support (5), alternatively to several supports, in the equipment (4). Alternatively, the equipment fixing device can be integrated into the fixing support (3) of the vehicle (2) and / or integrated into the support (5).

The equipment fixing device (1) is suitable for connecting various different types of vehicles (2) such as wheel loaders, different types of farm tractors, forklifts (forklift cranes), compact loaders, telescopic loaders , the so-called backhoe loader machines, etc. The present invention may even be used in other applications when appropriate.

The equipment fixing device (1) is suitable for use with several different types of equipment such as forks, pallet forks and different types of shovels such as cement buckets, snow buckets and other types of shovels and dredgers. It can also be conceived that the equipment for the treatment of garbage, the equipment for winding cables (wire), the work trays, the arms for handling materials, the gripping forks or other types of equipment are connected to the fixing device team.

Such components are of course included to the extent necessary to achieve proper and complete function.

The angle of rotation between the first frame assembly (7) and the second frame assembly (8) is altered by the longitudinal extension and retraction of the hydraulic cylinder (16). The angle of rotation between the second frame assembly (8) and the third frame assembly (9) is altered by the longitudinal extension and retraction of the hydraulic cylinder (17).

The equipment fixing device (1) is made up of at least a second connection device (18) with which the equipment fixing device is fixed to the fixing support (3) of the vehicle (2).

Preferably, the equipment fixing device (1) includes a device (function) with which the fixed support (5) can tilt up or tilt down.

The mutual change in the positions of the first frame set (7) and the second frame set (8) relative to the third frame set (9) is achieved by at least one maneuvering device. The first frame assembly (7) and the second frame assembly (8) are in the exemplary Figure at an angle of approximately 90 degrees relative to the third frame assembly. This angle of rotation may, however, vary, to larger or smaller, relative to the angle shown in the Figures.
