Description

Multifunctional work cage with improved properties

The present invention relates to a work cage for use in a mobile or non-mobile device for performing work at locations that are difficult to reach, such as at great heights.

Such work cages are generally known and are used, for example, in aerial platforms, telehandlers, cranes, etc. A disadvantage of the known work cages is that they are generally quite small and that the allowable load and the number of persons allowed in the work cage are generally relatively low.

EP 1 775 255 describes a working cage for mounting on the end of a telescopic arm. The working cage has two folding walls 21, 21 ', see figures 1-5. Fold-out handrail structures are also provided.

US 6,439,341 describes a connecting piece with a pivoting mechanism (around axis A) and with a landing sensor 19, see figure 2 and figures 7 and 8. The landing sensor 19 comprises a first part 21 connected to a lifting arm and a second part 23 connected to the working platform. A pivotable connecting rod 37 with a strain gauge 11 is mounted between this first part 21 and this second part 23, see figure 8 and figure 9.

The invention has for its object to propose a multifunctional work cage with improved properties.

To this end, the invention is distinguished in that the working cage comprises a first platform with first handrail structures, at least one second platform with second handrail structures, and adjustable connecting means between the first platform and each second platform, all such that each second platform forms an extension from the first platform.

In this way a multifunctional cage with an adjustable width is obtained.

The term "adjustable connection means" should be interpreted broadly in the sense that the total width of the working cage can be adjustable, for example, stepwise or continuously, or that the width can for instance only assume two values. For example, telescopic connecting means can be provided that allow a large number of variable widths. According to another embodiment, however, hinges can also be provided between the first platform and each second platform, wherein each second platform is movable between a collapsed and an unfolded position, such that two or more different total widths are possible depending on the number of second platforms .

Furthermore, the dimensions of the work cage are preferably chosen such that the work cage is easily transportable in the position with minimum width.

According to a preferred embodiment, the at least one second platform consists of two side platforms at both ends of the first platform.

Other advantageous embodiments are described in the dependent claims 2-11.

According to another aspect, the invention relates to a connecting piece for pivotally connecting a loadable platform to a machine, preferably for connecting a work cage to a device for performing work at locations that are difficult to reach, comprising: - a bearing structural component adapted to exhibit a bend when loading the platform, and - measuring means for measuring the magnitude of this bend. Such measuring means make it possible to detect an overload of the platform in a simple manner.

The measuring means are preferably adapted to measure the deflection in different directions. This has the advantage that an overload in a certain direction can be detected.

Advantageous embodiments of the connecting piece may, for example, have one or more of the following properties: - the bearing structural component is adapted to exhibit a bend at high loads that is clearly measurable by the measuring means; - the bearing construction component is a profile piece, a hollow or full rod, or any other element that can exhibit a measurable bend; - the supporting construction component is mounted substantially parallel to the pivot axis of the connecting piece; - the load-bearing structural component has a rectangular cross-section; - the measuring means comprise a first set of measuring means on a first side, a second set of measuring means on a second opposite side and a third set of measuring means on a frontal side between the first and second side, all such that loads can be measured in different directions; - the measuring means comprise at least one strain gauge.

- the measuring means are coupled with warning means for warning the user in the event of an overload.

- the supporting construction component can be connected to the platform by means of clamping means.

According to yet another aspect, the invention relates to a connecting piece for pivotally connecting a loadable platform to a machine, preferably for connecting a work cage to a device for performing work at locations that are difficult to reach, comprising: - a first tubular rigid body intended to be connected to the platform, the axis of the first tubular rigid body in the mounted position being substantially parallel to the platform, - a second tubular rigid body intended to be connected to the machine, wherein the axis of the second tubular rigid body in the mounted position is substantially parallel to the platform, a pivot axis between the first and the second tubular bodies, substantially perpendicular to the axes of the first and second tubular bodies.

Such a construction has the advantage of being very rigid, simple and compact in comparison with the existing connecting pieces.

According to a preferred embodiment, cylinders for controlling the pivoting are mounted in the second tubular body. The second tubular body can further be provided with a support platform for an auxiliary tool.

The details described below in the embodiment variants shown in the figures can each be added individually or in combination to one of the embodiments of the invention described above.

The present invention will be further elucidated on the basis of a number of non-limiting exemplary embodiments with reference to the attached drawings, in which:

Figure 1 is a front perspective view of a first embodiment of a work cage according to the invention; Figure 2 is a larger-scale view of the left-hand side of the embodiment of Figure 1;

Figure 3 is a rear perspective view of the embodiment of Figure 1;

Figure 4 is a detailed view of the connection between the working cage and the working arm in the embodiment of Figure 3;

Figures 5A-C schematically illustrate a front view of a second embodiment of a working cage according to the invention in a collapsed position, an intermediate position and an unfolded position, respectively;

Figure 6 illustrates a possible implementation of the rod 25 of Figure 4 on which strain gauges are mounted.

Figure 1 illustrates a connecting piece 2 which can be designed in any way, to which a working cage 1 according to an embodiment of the invention is attached. The connecting piece 2 is intended for connection to a mobile or non-mobile device, such as for example a working platform, a telescopic handler, a device with a boom, a forklift, etc. In the shown embodiment the connecting piece 2 is provided with a platform on which an auxiliary crane 20 is mounted, but those skilled in the art will understand that this is an option that can be omitted. Depending on the machine with which the work cage is combined, one or more adapted connecting pieces will typically be provided. In the case of a scissor lift, the work cage will typically be connected at its bottom to the scissor arm. An example of a telescopic handler or crane with which the work cage according to the invention can be combined is described in the Belgian patent BE 1014361 in the name of the applicant. An example of a telescopic boom with which the working cage can be combined is described in the Belgian patent BE 1012862 also in the name of the applicant. The work cage can also be used in combination with a crane.

The working cage 1 is constructed according to a possible embodiment of the invention. The working cage 1 comprises an elongated central working platform 3 and two side platforms 4, 4 'which extend at opposite ends of the elongated central platform 3, in line therewith.

The central platform 3 has a bottom 10 and two substantially parallel handrail structures 5a, 5b. Each side platform 4 has a bottom 11, two parallel handrail structures 6a, 6b and a closure 7 at the end that is furthest away from the central platform. The closure 7 can for instance be designed as a double-secured door, such that two operations are required to open such a door. For example, the door may be hinged on one side to the handrail structure 5a and on the other hand, for example, a spring latch may be provided between the door and handrail structure 5b, in combination with a hook / flange system, such that on the one hand the spring latch must be unlocked and on the other hand, the door must be lifted and opened to open the door. Furthermore, the door can be provided with a detection system that detects whether the door is open or closed. By providing such doors, loads can easily be loaded from the side onto the work platform.

The bottom 11 is provided with anchor points 8 at the end adjacent to the bottom 10 of the central platform 3 for anchoring a load in the work cage.

Such anchor points can of course also be provided at other places.

The cage is preferably made from very high-quality light materials, wherein, for example, specially rolled, lightweight profiles with a high moment of inertia are used, all such that the inherent weight is very low in relation to the permitted load. The materials that are eligible for the work cage include high strength steels, aluminum, in particular the aluminum alloys typically used in aircraft, strong plastics, composite materials, etc.

In the embodiment shown, the side platforms 4, 4 'are slidably mounted with respect to the central platform 3. More in particular, the longitudinal sides of the central platform 3 are provided with U profiles 12a, 12b, in which sides 13a, 13b of a side platform 4 can be guided, see figure 2. These sides 13a, 13b are here shaped as tubular profiles with a height that is adapted to those of the U profiles.

Those skilled in the art will understand that many variants are possible in order to achieve such a telescopic function, for example all kinds of guide rails. According to another variant, the side platforms 4, 4 'can be foldably connected with respect to the central platform 3, wherein the side platforms 4, 4' can for instance be folded out from a vertical position to a horizontal working position.

According to yet another variant schematically illustrated in Figs. 5A-C, the side platforms 104, 104 'are movable from a collapsed position in which the side platforms are located on the central working platform 103 to an unfolded position in which the side platforms are in line with the central work platform 103. In the embodiment shown, for each side platform 104, 104 'there are a pair of hinged mounted bearing arms 105a, 105b; 105a ', 105b' are provided (only 105a and 105a 'are shown in the figure, but on the other side of the side platforms arms 105b, 105b' are provided in an analogous manner). These support arms make a circular lateral movement to move the side platforms 104, 104 'from the collapsed to the collapsed position, see Figures 5A-C.

In the embodiment shown, the bottom 10 of the central platform has a length lc, for example 7 meters, and a depth d, and the side platforms have a bottom 11 with a length lz that is substantially equal to half the length lc. In this way a working cage with a variable length can be obtained, wherein the maximum length is equal to twice the length of the central platform minus the minimum overlap (2 * 12) between the central platform and the side platforms. In the case that the length 1c is 7 meters, the maximum length can be, for example, 13m. Those skilled in the art will understand, however, that the dimensions, and in particular the length and depth dimensions, may be adapted in function of the needs of the user and / or in function of the application.

The connection between the handrail structures of the central platform 3 and the side platforms 4, 4 'typically takes place with a end-stroke protection 9a, 9b such as two hooks that engage each other, whether or not in combination with a lock or transfer locks, The connection between the bottoms 10 11 can, for example, be done in an analogous manner. According to a variant, the side platforms 4, 4 'can be locked in different, not fully extended positions 3 relative to the central platform.

The bottom of the bottom of the central platform 3 can be further reinforced with stiffening ribs 15, 16, see figures 1 and 3. Depending on the length and depth of the platform, the desired strength, etc., these can be to a greater or lesser extent are arranged in certain positions or according to a certain pattern, such as according to a honeycomb structure, a diagonal structure, a lateral structure, etc.

Figure 3 shows a rear view of the working cage of Figure 1. In this figure, in particular, the connecting piece 2 between the working cage 1 and a random machine (not shown) is shown, which connecting piece is further shown in detail in Figure 4.

In the embodiment shown, the connection consists of a load-bearing tubular structure 2 that permits a swiveling of the work cage through 180 degrees. According to a variant, a construction can be provided which swivels from 0 to 360 degrees or a 360 degrees continuous rotation. Furthermore, an overload detection system can be built in which is capable of detecting an overload in the different directions (frontal, left / right).

The handrail structure 5b is reinforced on the side with the bearing tubular structure 2 with elements 17, 18, 19. Furthermore, a frame 21 and two mounting profiles 22, 23 are provided for mounting the connecting piece 2. A rod 25 of rectangular cross-section is mounted between the fixing profiles 22, 23 with the aid of upper (not shown) and lower clamping blocks 38, 39 between which an upper and lower end of the rod 25 is clampingly mounted, respectively.

In the embodiment shown, the rod 25 can, in addition to a supporting function, also have a nuisance detection function. To that end, the rod 25 can be provided with one or more strain gauges, i.e. strips whose resistance changes with deformation. With a bending of the rod as a result of loads in the working cage, this bending can therefore be measured. For mounting the strain gauges, threaded holes may be provided in the rod 25. According to an advantageous embodiment shown in Figure 6, three strain gauges are mounted on the rod 25: - a first strain gauge 55 on a frontal side 51, mounted with bolts in holes 53a, 53b; a second strain gauge 54 on a right-hand side 50 mounted with bolts in holes 52a, 52b; and - a third strain gauge, not visible in the figure, on the left-hand side opposite the right-hand side.

In this way the bending of the bar can be measured in different directions: frontal, left and right.

Two swivel feet 31a, 31b are welded to the rod 25, here in the form of horizontal flanges. Each pivot foot 31a, 31b is provided with a pivot axis 32a, 32b which extend in line with each other. The pivot shafts 32a, 32b are connected to a support tube 27 in which cylinders 29a, 29b are mounted for controlling the pivoting movement. The carrier tube 27 can be connected to any machine by means of a hook 35. However, it will be understood by those skilled in the art that a different type of connecting means may be used instead of a hook. The carrier tube 27 is provided with recesses 36a, 36b (36b is not visible in Figure 4, but is opposite 36a), whereby the cylinders 29a, 29b respectively protrude. These recesses have dimensions adapted to the necessary freedom of movement for the cylinders 29a, 29b.

Furthermore, a thick-walled tube 24 is provided between the support feet, parallel to the pivot axes, which tube 24 on the one hand reinforces the construction by forming a connecting piece between the support feet 31a, 31b, and on the other hand forms a drop point for the piston rods 33a, 33b of the cylinders 29a , 29b. To this end, the tube 24 is provided with mounting flanges 30 with which the ends of the piston rods 33a, 33b are hingedly connected with the aid of vertical pins 34a, 34b. Note that the piston rod 33b is shown in the disconnected position.

To further reinforce the whole, a stiffening tube 26 is mounted, typically welded, between the swivel feet 31a, 31b. This stiffening tube 26 here has end flanges, and is provided with holes 40, 41 to make the construction lights.

The support tube 27 may further be provided with a mounting platform 28 for a base 37 of a tool such as an auxiliary crane or a gallows.

Typical materials used for the load-bearing tubular structure 2 include high-strength steels, structural steel, steel.

The present invention is of course not limited to the exemplary embodiments described above and the person skilled in the art will understand that many other variants and modifications are conceivable that fall within the scope of the invention which is only determined by the following claims.
