Description

Technical Field

[0001] The present invention relates to a maintenance device for maintaining and / or repairing a shelf operator in a cold storage according to claim 1, a multi-layer shelf operator in a cold storage according to claim 6, and an apparatus for a main switch cabinet having a maintenance device and a shelf operator according to claim 8. Background Art

[0002] When using a shelf operator in a cold store, it is difficult to perform maintenance or repairs on the shelf operator due to the harsh ambient conditions that occur there, especially due to the low temperatures. The harsh ambient conditions are particularly an obstacle when performing maintenance or repairs on components arranged in the main switch cabinet of the shelf operator.

[0003] From DE 10 2013 102 778 A1 it is known to move a shelf handling machine used in a cold store for maintenance or repair into a maintenance area which is isolated from the cold store and can only be accessed through a gate. On the one hand, this has the disadvantage that maintenance is very time-consuming, since the shelf handling machine must be moved into the maintenance area and heated accordingly to avoid damage. As a result, the shelf handling machine is out of useful use for a correspondingly long time, thus reducing the cold store's throughput. On the other hand, the cost of providing such a maintenance area is very high and requires a correspondingly large space in a storage facility including a cold store.

[0004] It is also known that, for maintenance or repair in a cold storage, a multi-layer shelf operating machine installed therein is equipped with a cabin, which is directly connected to its main switch cabinet and forms a unit with its main switch cabinet, and the cabin is heated and accessible to maintenance personnel. This unit consisting of a main switch cabinet and a cabin can also be called an accessible main switch cabinet. However, the disadvantage of this cabin or unit is that it is heavier, so the energy required for running the multi-layer shelf operating machine is higher than that of the multi-layer shelf operating machine without such a cabin or unit. In addition, it is necessary to provide such a cabin or unit on each multi-layer shelf operating machine used in the cold storage, thereby generating high costs. Another disadvantage of this unit is that it occupies the entire width between two adjacent storage shelves, i.e. the entire width of the shelf channel. In order to comply with the escape route specified for the personnel working in the cold storage, the unit must be placed in a correspondingly high position on the multi-layer shelf operating machine, so that there are enough escape routes through the shelf channel below it. However, when the unit is arranged in this way, the maintenance personnel must climb a ladder to reach the cabin, which can endanger the safety of the maintenance personnel, for example, due to the risk of falling.

[0005] A further disadvantage of performing maintenance or repairs without a maintenance area or cabin is that the personal protective equipment then required may restrict freedom of movement and, in particular due to thick gloves, the tactile sensitivity of the maintenance personnel may also be limited, making maintenance or repairs more difficult. Summary of the invention

[0006] Therefore, the object of the present invention is to propose a maintenance device, a shelf operating machine and an apparatus having a maintenance device and a shelf operating machine main switch cabinet, thereby reducing the time and cost expenditure for maintaining and / or repairing the shelf operating machine used in the cold storage and improving the working conditions of the maintenance personnel.

[0007] This object is achieved by a maintenance device having the features of claim 1, a multi-level storage manipulator having the features of claim 6, and a device having the features of claim 8. Advantageous refinements are revealed in the dependent claims and the description.

[0008] According to the present invention, a maintenance device for maintaining and / or repairing a shelf operating machine in a cold storage is proposed, wherein the maintenance device has a frame that can be releasably fixed to a main switch cabinet of the shelf operating machine and a tarpaulin that can be releasably fixed to the frame, and the frame and the tarpaulin are designed and can be arranged relative to each other so that a maintenance space can be created on the main switch cabinet of the shelf operating machine.

[0009] In the installed state, the maintenance device resembles a tent, so it can also be described as tent-like. The frame is a rigid structural component which carries the tarpaulin in the installed state and with which the outer shape of the maintenance space can be essentially set. In contrast to the frame and the side walls used for known cabins, the tarpaulin is a flexible and lightweight barrier component with which a climate barrier can be created between the cold store and the maintenance space.

[0010] The tarpaulin is preferably designed in one piece, but a tarpaulin designed in multiple parts can also be provided. The tarpaulin can be made of a transparent or opaque material. Preferably, the material of the tarpaulin is reinforced plastic, which is also commonly used for truck tarpaulins. If the material of the tarpaulin is opaque, an observation window can be provided on the tarpaulin.

[0011] The maintenance space that can be created using the maintenance device can be understood as a closed space. However, maintenance personnel can enter this space through an opening, which can be closed, for example, by a zipper and / or Velcro and / or a magnetic strip. The size of the maintenance space is preferably selected so that it has enough space to accommodate personnel and the tools required for maintenance and / or repair.

[0012] Different temperatures can be generated in the maintenance space than in the cold store. In a cold store (also called a freezer, deep freezer or deep-frozen storage area), temperatures between about -18 and -32 degrees Celsius are usually generated. However, preferably a temperature between -5 and +5 degrees Celsius is achieved in the maintenance space. For this purpose, a fan heater can be used, for example, to heat the air in the maintenance space. The maintenance space can be heated exclusively only during maintenance and / or repairs.

[0013] By utilizing the maintenance device according to the invention, maintenance personnel can be effectively protected from environmental conditions, especially low temperatures, that occur in cold stores. Thus, more complex or longer maintenance work and repairs can also be performed on the main switch cabinet while complying with labor protection laws.

[0014] In the installed state of the service device, the tarpaulin hangs down from the frame or a component of the frame. At the lower end, the tarpaulin preferably ends in a structure arranged below the service device, so that the heat convection between the cold store and the heated service space is as small as possible, and thus the energy requirement for heating the service space is as low as possible.

[0015] The structure arranged below the maintenance device can be a load-bearing element on which the main switch cabinet also stands. Such a load-bearing element is provided depending on the design of the shelf operating machine. The load-bearing element can be, for example, a load-bearing frame on a multi-layer shelf operating machine. However, if the shelf operating machine is designed as a single-layer shelf operating machine, then - as described below - the main switch cabinet is arranged separately from the shelf operating machine, the load-bearing element can be, for example, a storage floor of a cold store. The load-bearing element or the load-bearing frame is preferably provided in such a way that the heat convection between the cold store and the heated maintenance space is kept as small as possible.

[0016] The components placed in the main switch cabinet preferably comprise electronic components for the control device of the shelf operating machine. In addition, other electronic components and / or electrical components and / or mechanical components and / or hydraulic components and / or pneumatic components can also be stored in the main switch cabinet.

[0017] The maintenance device according to the invention can be easily mounted on the main switch cabinet due to its division into frame and tarpaulin, and can also be disassembled and removed from the main switch cabinet. Compared with the known solutions with maintenance areas, the time required for maintenance can be reduced. As a result, the productivity of the shelf operator and the throughput of the cold store can be increased. In addition, there is no need to provide a separate maintenance area in the storage facility, which can save costs.

[0018] The maintenance device can also be designed specifically only for maintenance and / or repair periods and can be stored separately from the main switch cabinet between maintenance and / or repair operations or - in the case of a multi-layer rack handling machine - separately from the rack handling machine, for example outside the rack aisle. Compared to known solutions with a compartment, the weight of the multi-layer rack handling machine can be reduced, thereby reducing the energy required for acceleration and making the multi-layer rack handling machine more flexible. The productivity of the rack handling machine and the throughput of the cold store can thus be increased. For several main switch cabinets or multi-layer rack handling machines, a single maintenance device can also be used, which can save costs compared to known solutions with a compartment.

[0019] Advantageously, provision is made for the frame and the awning to be designed and arranged relative to one another in such a way that three side walls and a roof can be formed by them to produce a maintenance space.

[0020] The fourth side wall of the maintenance space can be formed by a suitable surface on the main switch cabinet in the installed state of the maintenance device. In the closed state of the main switch cabinet, this is in particular one or more doors of the main switch cabinet. In the open state of the main switch cabinet, this is in particular its rear wall. In other words, the frame and the tarpaulin are then arranged on the main switch cabinet in such a way that the main switch cabinet closes the maintenance space on one side. The floor of the maintenance space is then quadrilateral, preferably rectangular.

[0021] The three side walls can be provided with magnetic strips at their edges, for example, by which the side walls can be releasably connected to each other or to a shelf operating machine, in particular a main switch cabinet. The connection can be removed in order to open the maintenance space, for example to allow maintenance personnel to enter.

[0022] When the awning fabric is designed in one piece, it is preferably cut in such a way that the three side walls and the roof are designed in an essentially twist-free and unnecessary overlapping state.

[0023] It is also conceivable that the frame and the tarpaulin are designed and can be arranged such that two or four or more side walls can be formed by them to produce a maintenance space, so that the maintenance space then has a triangular or pentagonal or polygonal floor.

[0024] It is particularly advantageously provided that the frame comprises at least one pivot part which is provided with first pivot means, in particular a groove, an elongated hole or a bolt, for forming a releasable pivot connection with the main switch cabinet.

[0025] The pivot part can be configured, for example, in a U-shape, an L-shape, a T-shape or an I-shape. The frame can also comprise two or more pivot parts of identical or differently configured.

[0026] The first pivoting means can be connected to the second pivoting means to establish a releasable pivot connection, the second pivoting means being arranged on the main switch cabinet and corresponding to the first pivoting means. As a result, at least one pivoting part can be releasably fixed to the main switch cabinet. The first pivoting means designed as a groove or an elongated hole can be hooked on the second pivoting means designed as a bolt. If the first pivoting means is a bolt, the situation is reversed.

[0027] The second pivoting device does not necessarily belong to the maintenance device. It can also belong to a shelf operating machine or a main switch cabinet, and is particularly not specially configured for the maintenance device.

[0028] It is provided that at least one pivoting part is initially oriented parallel to the upwardly directed extension direction of the main switch cabinet when it is placed on the main switch cabinet. The pivoting part is then in a non-pivoted position. The pivoting part is then pivoted about an axis formed by the first pivoting means and / or the second pivoting means until the pivoting part is oriented substantially perpendicularly to the upwardly directed extension direction of the main switch cabinet. The pivoting part is then in a pivoted position. This simplifies the installation of the frame.

[0029] As an alternative or in addition to the at least one pivoting part, the frame can also have a generally non-pivotable frame part to which the awning can be fastened.

[0030] It is also particularly advantageously provided that the frame comprises at least one supporting element, wherein the at least one pivot element can preferably be supported in a pivot position by means of the supporting element.

[0031] Alternatively, the support element can also be used to support a normally non-pivotable frame element, in particular to relieve the fastening points on the main switch cabinet from load.

[0032] The support part is arranged in particular at the end of the pivoting part or the usually non-pivotable frame part facing away from the main switch cabinet. The support part can be supported on the load-bearing part or the load-bearing frame. When the maintenance device is used on the main switch cabinet of the multi-storey storage operating machine, the support can also be supported on the railing of the multi-storey storage operating machine.

[0033] The support member may also be used to move the pivoting member from the non-pivoting position to the pivoting position.

[0034] The frame can also comprise two or more support parts, wherein each support part in particular supports a pivoting part or a generally non-pivotable frame part in the mounted state of the maintenance device. It is also conceivable that a support part supports a plurality of pivoting parts or generally non-pivotable frame parts, or that a pivoting part or a generally non-pivotable frame part is supported by a plurality of support parts.

[0035] It is also conceivable that the frame is designed in one piece, so that the support part forms a unit with the pivot part or the generally non-pivotable frame part.

[0036] In an advantageous and structurally simple manner, the frame, preferably the pivoting part, is provided with at least one first fastening means, in particular a pin or a hook, and the awning is provided with at least one second fastening means, in particular an eyelet, corresponding to the first fastening means, wherein the awning can be releasably fastened to the frame by connecting the first fastening means to the second fastening means.

[0037] Preferably, the frame has a plurality of, in particular four, first fastening means, and the awning has a plurality of, in particular four, corresponding second fastening means. These fastening means are preferably arranged in such a way that the awning can be fixed to the frame in a uniformly distributed manner along the frame.

[0038] If the frame comprises a pivoting part, the awning is preferably fixed to the pivoting part when the pivoting part is in the non-pivoting position.The awning is prevented from sliding off by the connection between the first and second fastening parts.

[0039] The invention also relates to a multi-layer shelf operating machine for use in a cold storage, wherein the multi-layer shelf operating machine comprises a lower traveling mechanism, at least one column and a lifting carriage with a load pickup device movable on the column. According to the invention, the multi-layer shelf operating machine has a main switch cabinet, which is arranged directly above the lower traveling mechanism and is inaccessible.

[0040] In the context of the present invention, the term "directly" means that in the multi-layer storage rack manipulator according to the present invention, there is no escape route between the lower running gear and the main switch cabinet. In particular, no structure is provided between the lower running gear and the main switch cabinet, whereas in the known solutions with a cabin, a structure for climbing to the main switch cabinet is required.

[0041] However, it is not excluded that the multi-layer shelf operating machine according to the present invention has a component such as a supporting frame for the main switch cabinet between the lower traveling mechanism and the main switch cabinet.

[0042] In the context of the invention, the term "inaccessible" means that the main switch cabinet must not be so large that, in addition to the components housed therein, a person has room to stand, as is the case, for example, with known solutions with a unit consisting of a compartment and a main switch cabinet. In other words, the main switch cabinet is inaccessible. Nevertheless, the main switch cabinet of the multi-level storage manipulator according to the invention is accessible via doors and / or flaps, so that the components housed therein can be worked on for maintenance and / or repair.

[0043] In the main switch cabinet of the multi-layer shelf operating machine, a control device of the shelf operating machine, also called an onboard control device, or its electronic components are particularly arranged. As mentioned above, other components can be arranged in the main switch cabinet. The maintenance device according to the invention can be installed on the main switch cabinet of the multi-layer shelf operating machine according to the invention. In addition to the main switch cabinet, another control cabinet and / or control box can also be provided on the multi-layer shelf operating machine, in which other components are arranged. The multi-layer shelf operating machine according to the invention can also be assigned another main switch cabinet, which is arranged separately from the multi-layer shelf operating machine in the cold storage, in particular arranged outside the shelf aisle.

[0044] According to the type, the multi-layer rack handling machine is a single track rail vehicle for depositing and removing storage goods in multiple (preferably four or more) or all storage rack layers of storage racks. The storage goods can be, for example, pallets, containers, crates, boxes, bags and / or individual items. The multi-layer rack handling machine can also serve multiple storage racks, for example, storage racks adjacent to each other in a rack aisle, or storage racks arranged in multiple rack aisles.

[0045] The multi-layered storage handling machine, also known in English as a "Stacker Crane" or "Storage and Retrieval Unit", may have, in addition to a lower running gear, an upper running gear arranged at the end of the column facing away from the lower running gear. The multi-layered storage handling machine can travel on the top crossbeam by means of guide rollers arranged on the upper running gear. The multi-layered storage handling machine may include other elements, such as a lifting mechanism with a transmission cable or a transmission chain, a climbing ladder and a power supply.

[0046] The multi-layer rack handling machine is movable in three spatial directions or axes. The lower running gear, in particular with wheels arranged thereon, is used to move the multi-layer rack handling machine along a track, which is in particular arranged in the racking channel. The uprights arranged on the lower running gear and substantially perpendicular to the track are used to raise and lower the lifting carriage along the uprights. The load pickup device of the lifting carriage is movable substantially perpendicular to the track and substantially perpendicular to the gantry, i.e. transversely to the travel direction of the multi-layer rack handling machine, and is used to pick up and put down the stored goods.

[0047] The multi-layer shelf manipulator according to the invention is specially designed for use in cold stores and has, for example, materials and lubricants suitable for this purpose.

[0048] The horizontal main extension direction of the main switch cabinet extends parallel to the movement direction of the multi-layer rack handling machine, i.e. parallel to the main extension direction of the storage rack. In front of the main switch cabinet, i.e. viewed in the main extension direction of the storage rack, next to the main switch cabinet, a platform, also referred to as a base, of the multi-layer rack handling machine is preferably arranged. In particular, the maintenance device is arranged above the platform so that maintenance personnel can "stand" on the platform and in the maintenance space created by the maintenance device.

[0049] The multi-layered storage handling machine according to the present invention has the following advantages: since there is no need to climb a ladder, the safety of the maintenance personnel is improved. In addition, compared with known solutions, the weight of the storage handling machine is reduced due to the cancellation of the cabin.

[0050] It is particularly advantageously provided that the interior of the main switch cabinet is not heated.

[0051] The electronic components housed in the main switch cabinet are designed to be cold-resistant. Cold-resistant electronic components currently refer to electronic components that can withstand the low temperatures generated in the cold storage when they are switched off. Therefore, it is not necessary to heat the main switch cabinet to avoid damaging the switched-off electronic components.

[0052] The present invention further relates to an equipment in a cold storage, which has a maintenance device according to the present invention and a main switch cabinet of a shelf operating machine, wherein the maintenance device is installed on the main switch cabinet.

[0053] In the device according to the invention, a maintenance space is thus created on the main switch cabinet. Since the maintenance device is easy to install and remove on the main switch cabinet, the maintenance device according to the invention can be installed on the main switch cabinet only during maintenance and / or repair, and the device according to the invention can also be formed only during maintenance and / or repair.

[0054] In a first particularly advantageous embodiment, it is provided that the shelf operating machine is a multi-storey shelf operating machine according to the invention and that the maintenance device is mounted on a main switch cabinet provided on the shelf operating machine.

[0055] In other words, the maintenance device in the installed state is then arranged at or on the multi-layer shelf operating machine according to the present invention. Thus, a maintenance space is formed on the multi-layer shelf operating machine, in particular above the platform.

[0056] In a further advantageous embodiment, it is provided that the storage rack operating machine is a multi-storey storage rack operating machine, and that the main switch cabinet is arranged separately from the multi-storey storage rack operating machine in the cold storage, and the maintenance device is mounted on the main switch cabinet.

[0057] The multi-layer shelf operating machine may be the multi-layer shelf operating machine according to the present invention, or a multi-layer shelf operating machine known from the prior art.

[0058] In this embodiment, the main switch cabinet is particularly arranged outside the shelf aisle. The main switch cabinet stands on a supporting member, which is particularly formed by a warehouse floor, and the warehouse shelves are also vertically erected on the warehouse floor.

[0059] The main switch cabinet is associated with at least one multi-level storage rack operating machine, ie is connected thereto in terms of control technology and / or power supply technology.

[0060] In another advantageous embodiment, it is provided that the storage rack operating machine is a single-layer storage rack operating machine, and the main switch cabinet is arranged separately from the single-layer storage rack operating machine in the cold storage, and the maintenance device is installed on the main switch cabinet.

[0061] Compared with the previously described embodiment of the shelf operation machine, the single-layer shelf operation machine (also referred to as shuttle) preferably only serves a single storage shelf layer of the storage shelf. However, the single-layer shelf operation machine can also be designed to enable it to serve several, particularly two or three storage shelf layers.

[0062] The single-layer rack handling machine can move along the rack aisle on two tracks. These tracks are arranged in one of the storage rack layers assigned to the single-layer rack handling machine. Each track is fixed to one or a part of the storage racks that are opposite to each other and separated by the rack aisle.

[0063] The single-layer rack operator can load and unload storage goods on both sides of the rack channel using a load pick-up device to deposit or remove storage goods. The single-layer rack operator can switch between storage rack layers through a lift optionally provided in the storage rack.

[0064] Single-layer rack handling machines are also specially designed for use in cold stores and have, for example, materials and lubricants suitable for this application.

[0065] The main switch cabinet belonging to one or more single-layer shelf operators is arranged separately from the one or more single-layer shelf operators, in particular arranged outside the shelf channel. The main switch cabinet is vertically mounted on a support member, which is particularly formed by a storage floor, and the storage shelves are also erected on the storage floor.

[0066] The electronic components for the control device of the one or more single-layer shelf operating machines are preferably arranged in the main switch cabinet. Each single-layer shelf operating machine is connected to the main switch cabinet in order to transmit control commands, in particular via a contact wire. As mentioned above, other components can be arranged in the main switch cabinet. In particular, electrical components for supplying power to at least one single-layer shelf operating machine are also arranged in the main switch cabinet, wherein each single-layer shelf operating machine is connected to the main switch cabinet, in particular also via a contact wire.

[0067] In addition to the components arranged in the main switch cabinet, the single-layer shelf operating machine itself can also have other components, such as an onboard control device. These other components are particularly arranged in a switch box on the single-layer shelf operating machine.

[0068] The invention also relates to a cold store having a device according to the invention, at least one shelf operating machine and at least one storage shelf. Preferably, the cold store comprises a plurality of storage shelves and a shelf operating machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] Figure 1A schematic side view of an embodiment of the apparatus according to the invention is shown with an embodiment of a maintenance device 1 according to the invention.

[0080] The device according to the present invention includes, in addition to the maintenance device 1, a main switch cabinet 200, wherein the maintenance device 1 is mounted on the main switch cabinet 200. The main switch cabinet 200 belongs to a shelf operating machine 100 used in a cold storage. The main switch cabinet 200 may be a main switch cabinet of a multi-layer shelf operating machine 100' (see also Figures 6 to 8 ), or the main switch cabinet of a single-layer rack operating machine or several single-layer rack operating machines.

[0081] If the main switch cabinet 200 belongs to a multi-layer shelf operating machine 100', the main switch cabinet 200 is arranged on the shelf operating machine 100 itself. If the main switch cabinet 200 belongs to one or more single-layer shelf operating machines, the main switch cabinet 200 is arranged separately from the shelf operating machine 100 in the cold storage.

[0082] The main switch cabinet 200 stands on a supporting member 201. In the case where the main switch cabinet 200 belongs to at least one single-layer shelf handling machine, the supporting member 201 is particularly formed by the warehouse floor of the cold storage. In the case where the main switch cabinet 200 belongs to a multi-layer shelf handling machine 100', the supporting member 201 is particularly a supporting frame 201' on the multi-layer shelf handling machine 100' (see also Figures 6 to 8 ).

[0083] The maintenance device 1 comprises a frame 2 releasably fixed to the main switch cabinet 200 and a tarpaulin 10 releasably fixed to the frame 2. The frame 2 and the tarpaulin 10 are designed and arranged relative to each other so that a maintenance space 50 is created on the main switch cabinet 200.

[0084] The frame 2 is a rigid structural component, with which the outer shape of the maintenance space 50 can be substantially predetermined. The tarpaulin 10 is a flexible and lightweight barrier component, with which a weather barrier can be created between the cold store and the maintenance space 50. In the illustrated installed state, the maintenance device 1 resembles a tent, so that it can also be described as tent-like.

[0085] In order to create the maintenance space 50, three side walls 51 and a ceiling 52 are formed by the maintenance device 1. Of these side walls 51, only one side wall 51 is shown in this view. The fourth side wall 51 of the maintenance space 50 is formed by an appropriate surface on the main switch cabinet 200. In the closed state of the main switch cabinet 200, this is the door of the main switch cabinet 200. In the open state of the main switch cabinet 200, this is its rear wall. The maintenance space 50 currently has a quadrilateral floor.

[0086] The maintenance space 50 is a closed space, however, maintenance personnel can enter the space through an opening (not shown), which can be closed, for example, by a zipper and / or Velcro and / or a magnetic strip. The size of the maintenance space 50 is selected so that it has enough space to accommodate personnel and tools required for maintenance and / or repair. The maintenance space 50 can be heated to facilitate maintenance and / or repair of the components arranged in the main switch cabinet 200.

[0087] In the embodiment shown, the frame 2 is formed by a pivoting member 3 and a supporting member 4. Alternatively, a plurality of supporting members 4 may be provided. The pivoting member 3 is supported by the supporting member 4 against the bearing member 201.

[0088] In the present case, the pivoting member 3 is configured as a U-shape and has a first pivoting device 3a designed as a groove at the ends of the two legs. The first pivoting device 3a is connected to the second pivoting device 20, which is fixed on both sides of the main switch cabinet 200 and is designed as a bolt.

[0089] The pivot part 3 also has four first fastening means 5 designed as pins, of which only two are shown. Instead of pins, hooks can also be provided as first fastening means 5. The two first fastening means 5 shown are arranged on the pivot part 3 at a distance from each other, just like the two first fastening means 5 arranged behind them in this view. In the top view, a rectangular pattern is thus produced. These first fastening means 5 are then arranged so that the awning 10 can be fixed to the frame 2 evenly distributed along the frame 2.

[0090] The awning fabric 10 can be releasably fastened to the pivot part 3 by means of the first fastening means 5 and second fastening means (not shown) corresponding thereto.

[0091] Instead of the integral design of the pivoting member 3, the frame 2 may also have two pivoting members 3, and these pivoting members 3 are pivotably connected to one side of the main switch cabinet 200. Each pivoting member 3 may then be supported by a support member 4, or the two pivoting members 3 may be supported together by a single support member 4. In the case of two pivoting members, the first pivoting means 3a may be designed as an elongated hole.

[0092] Alternatively or in addition to the at least one pivot part 3 , the frame 2 can also have an overall non-pivotable frame part to which the awning 10 can be fastened.

[0093] The tarpaulin 10 hangs down from the pivoting member 3, and its lower end terminates at the carrying member 201. As a result, the maintenance space 50 is closed in this area, and heat convection between the cold storage and the heated maintenance space 50 is minimized.

[0094] Figure 2yes Figure 1 A schematic side view of the device is shown in a first step of installing the maintenance device 1 on the main switch cabinet 200 .

[0095] In a first step of installation, the pivot part 3 is placed in a non-pivoted position on the main switch cabinet 200 and is releasably fixed thereto. To this end, the pivot part 3 is pushed in the region of the first pivot means 3a designed as a groove onto the second pivot means 20 designed as a screw, thereby producing a pivot connection. In the non-pivoted position, the pivot part 3 is oriented parallel to the upwardly directed extension direction of the main switch cabinet 200.

[0096] Figure 3 yes Figure 1 A schematic side view of the device is shown in a second step of installing the maintenance device 1 on the main switch cabinet 200 .

[0097] In a second step of the installation, the awning 10 is releasably fastened to the pivot part 3 by means of second fastening means (but not shown) arranged thereon, or to the first fastening means 5 arranged thereon. To this end, the second fastening means, which are designed in the present case as eyes, are pushed onto the first fastening means 5, which are designed as pins.

[0098] Figure 4 yes Figure 1 A schematic side view of the device is shown in a third step of installing the maintenance device 1 on the main switch cabinet 200 .

[0099] In a third step of the installation, the pivot part 3 together with the tarpaulin 10 releasably fastened thereto is pivoted from the non-pivoted position to the pivoted position (see Figure 5 ). For pivoting, a support part 4 can also be used.

[0100] Figure 5 yes Figure 1 A schematic side view of the device is shown in a fourth step of installing the maintenance device 1 on the main switch cabinet 200 .

[0101] The pivot part 3 is shown here in a pivoted position, wherein the pivot part 3 is oriented substantially perpendicularly to the upwardly directed extension direction of the main switch cabinet 200. A tarpaulin 10 , which is releasably fastened thereto, hangs down from the pivot part 3.

[0102] In the fourth and final step of the installation, the support part 4 is positioned below the pivot part 3 so as to support the pivot part 3 in the pivoted position on the carrier part 201. The support part 4 is arranged at the end of the pivot part 3 facing away from the main switch cabinet 200, so that the maintenance space 50 is as easy to access as possible. In addition, if the main switch cabinet 200 belongs to the multi-layer shelf operating machine 100' and is therefore arranged on the multi-layer shelf operating machine 100', a sufficient escape route through the maintenance device 1 is provided (see Figures 6 to 8 ).

[0103] Figure 6 A schematic perspective view of another embodiment of the device according to the invention is shown.

[0104] In the embodiment of the device shown here, the main switch cabinet 200 belongs to the shelf operating machine 100 designed as a multi-layer shelf operating machine 100'. Therefore, the main switch cabinet 200 is arranged on the shelf operating machine 100 itself and is directly located on the running mechanism 102 of the multi-layer shelf operating machine 100' (see Figure 7 ) above. In addition, the main switch cabinet 200 cannot be entered. The main switch cabinet 200 has two doors 200a through which maintenance personnel can enter the main switch cabinet 200. Optionally, the interior of the main switch cabinet 200 is not heated.

[0105] The main switch cabinet 200 stands on a supporting part 201, which is currently designed as a supporting frame 201'. The multi-layer shelf operating machine 100' currently has a platform 104, which forms a continuous element with the supporting frame 201'. A railing 103 is provided at the end of the platform 104 facing away from the main switch cabinet 200.

[0106] The maintenance device 1 shown here is not provided with the tarpaulin 10, so that the frame 2 and the maintenance device 1 can be seen to be fixed to the main switch cabinet 200. However, the size of the maintenance space 50 that can be manufactured can be guessed based on the arrangement and shape of the frame.

[0107] The frame 2 comprises a pivoting part 3 and a supporting part 4. The supporting part 4 supports the pivoting part 3 against the railing 103 of the multi-layer shelf operating machine 100'. A supporting point 4a is thereby created. However, such a supporting point 4a can also be arranged at another position on the multi-layer shelf operating machine 100', so that the pivoting part 3 is supported by the supporting part 4, for example, against a platform 104 arranged in front of the main switch cabinet 200.

[0108] Maintenance personnel can stand on the platform 104 to perform maintenance and / or repair on the main switch cabinet 200 or the components placed inside it. Two steps 105 are provided on the platform 104, which enable maintenance personnel to more easily reach the platform 104, which is arranged at a lower height above the storage floor of the cold storage. Compared with the known design of the multi-layer shelf operating machine 100' with an elevated cabin, maintenance personnel do not have to climb a ladder to reach the main switch cabinet 200. Therefore, falling accidents that endanger the safety of maintenance personnel are avoided.

[0109] The pivoting part 3 in the pivoting position is configured as a U-shape and has reinforcement struts 3b at its two corners and in the region of the fastening points. However, the reinforcement struts 3b are only optional within the scope of the present invention. In addition, the pivoting part 3 has four first fastening means 5 in total.

[0110] Figure 7 Shown according to Figure 6 Schematic side view of the device.

[0111] It can be clearly seen from this view that there are sufficient escape routes for people working in the cold storage between the main switch cabinet 200 and the railing 103 and between the main switch cabinet 200 and the support member 4. The tarpaulin 10 (not shown) has closable openings on both sides so that the escape route is not restricted by the tarpaulin 10 or is tolerably restricted by it. Alternatively, the tarpaulin 10 can be quickly removed from the frame 2 or the pivoting member 3 for escape.

[0112] The lower traveling mechanism 102 of the multi-layer shelf operating machine 100 ′ is schematically shown by a dotted-line frame, and the main switch cabinet 200 is arranged directly on the lower traveling mechanism 102 .

[0113] Figure 8 Shown according to Figure 6 Schematic front view of the device.

[0114] In this view it can be seen how the pivot connection formed by the first pivot means 3 a and the second pivot means 20 is designed between the pivot part 3 and the main switch cabinet 200 .

[0115] Fig. 9 A schematic folded perspective view of an embodiment of a maintenance device 1 according to the invention is shown.

[0116] In this view, the tarpaulin 10 is shown unfolded, although it is suspended from the pivoting part 3 in the installed state of the maintenance device 1 to form a weather barrier between the maintenance space 50 and the cold storage. The unfolded view clearly shows what contours the tarpaulin 10 has, that is, how the tarpaulin 10 is cut to form the side walls 51 and the roof 52.

[0117] In the present embodiment, the tarpaulin 10 is of one-piece design. However, a multi-part design of the tarpaulin 10 is also possible. Magnetic strips 11 are respectively arranged on the edges of the side walls 51, which are used to releasably connect the side walls 51 to each other or to releasably connect the side walls 51 to the main switch cabinet 200.

[0118] The magnetic strip 11 makes it possible that the maintenance space 50 can be closed and thus heated efficiently, but can also be temporarily opened for maintenance personnel to enter. As an alternative to the magnetic strip 11, a zipper or a Velcro fastener is also conceivable.

[0119] Since the tarpaulin 10 is designed to be opaque in the present case, viewing windows 10a are provided therein. These viewing windows are merely optional within the scope of the invention and can therefore also be omitted.

[0120] In this figure, a total of four first fastening parts 5 and their arrangement on the pivot part 3 can also be clearly seen.
