Description

The invention relates to a set of two transport devices for transporting a cable drum with a central bore.

According to the previously known type, cable drums are transported by inserting a supporting axle into a central bore of a cable drum. Next, the two ends of the support axle are lifted via a rope assembly for subsequent transporting of the cable drum, or are gripped by two human transporters and lifted for subsequent transporting of the cable drum. It is therefore advantageous that possibilities have been created to transport cable reels. In particular, if a cable drum, for example a fully wound cable drum, is to be transported up a hallway over steps, safe carrying by one, two or more human transporters without aids cannot be guaranteed, taking into account health and safety at work. However, the support axle has the problem that it does not prevent the cable drum from being displaced along its longitudinal axis, so that the cable drum permanently threatens to crush the hand or finger of a transporter, particularly when there are two human transporters of different sizes. The known devices therefore do not offer adequate health or occupational safety.

It is known from the prior art document US 139 029 A that a jack is used to move and support a crate, for example. To do this, insert a non-U-shaped serrated claw under the bottom of the box at one edge of the box, placing a fork against the top or side of the box and pressing on it so that the tips of the fork penetrate the box and pinch it secure positively. Other jacks are known in the art GB 2 390 997 A , GB 2 492 556 A , U.S. 4,098,442A and GB 2 171 352 A .

An alternative solution is in the patent application DD 2 04 458 A1 disclosed. According to this, a load hook for cable drums is provided, the center of gravity of which is selected in such a way that the load hook stabilizes itself after it has been inserted into the central bore of the cable drum. Two load hooks are used to safely transport the cable drum. Due to the shape of the load hook, it is intended to be anchored to the cable drum by means of a form fit without additional parts. The principle of the load hook can be used for cable drums of different masses and sizes; however, the strength of the material and the dimensions of the load hook must be varied accordingly.

The end of the load hook facing away from the cable drum is connected to a sling rope via a shackle. To transport the cable drum, the sling thus carries the cable drum. If two transporters are now transporting the cable drum, for example a fully wound cable drum, up a hallway over steps, each transporter will hold one end of the sling. Since the load hook stabilizes itself firmly after being inserted into the central bore of the cable reel, flexibility is made possible by a corresponding sling rope. The problem here, however, is that this flexibility of the sling reduces the safety of the transporters during transport. During a transport of the cable drum by two transporters, each transporter thus grips a sling. However, sling ropes are not suitable for ensuring that the hand of a transporter does not hit a front disk facing him. Thus, carriers are exposed to a risk of injury under the aforementioned circumstances. This conflicts with occupational safety. Occupational safety is the safety of employees at work, i.e. the control and minimization of risks to their safety and health. For example, it is part of occupational safety within the meaning of the Occupational Safety and Health Act in force in the Federal Republic of Germany, which requires measures to prevent accidents at work and work-related health hazards, including measures to organize work in a humane manner. The health and safety management of employees is one of the indispensable support processes of a company, primarily for human reasons, but also from an economic point of view: accidents and work-related illnesses cost both companies and society a lot of money.

It is therefore the object of the invention to create a transport device for transporting a cable drum that enables the cable drum to be transported safely by a human transporter. It should also be possible for two human transporters to each use a transport device for safely transporting the cable drum.

The object is achieved according to the invention by a transport device with the features of claim 1. Preferred embodiments of the invention are specified in the subclaims and the following description, which individually or in combination can represent an aspect of the invention.

According to the invention, a set of two transport devices for transporting a cable drum with a central bore and an axis of rotation is thus specified, each with a human transporter per transport device, each having the transport devices
a gripping means for gripping by a user while transporting the cable reel,
a longitudinal guide body arranged on the gripping means with a longitudinal extension axis,
a U-shaped hook arrangement arranged on the longitudinal guide body for hooking into the central bore of the cable reel, the hook arrangement having an outer web with an outer web extension axis, a load web and a hooking web with a hooking web extension axis, the hooking web being designed for abutment on the cable drum,
wherein the transport device has an adjusting element with a contact body for contacting an end disk of the cable drum, wherein the adjusting element is arranged on the longitudinal guide body such that it cannot rotate about the axis of longitudinal extent of the longitudinal guide body.

The basic idea of the present invention is that the adjustment element is secured with its contact body against twisting, also called non-rotatable, about the longitudinal axis of the longitudinal guide body on the longitudinal guide body. This significantly increases the safety of the transporter, especially in view of the quick completion of work, so that every professional activity of the transporter must be designed with as few risks as possible. This is achieved hereby. While a surprising twisting of the adjusting element can lead to the transporter being able to lose his balance while transporting the cable drum due to the weight shift of the changing cable drum, this risk is eliminated by a non-rotatable design of the adjusting element according to the invention. This also accelerates the hooking of the hooking web into the opening of a front disk, so that the work processes can be accelerated because it is not necessary to readjust manually during each hooking process so that the contact body is rotated as required.

The invention relates to a set of two transport devices, each transport device being able to be used by a human transporter to open an end plate of a cable drum to be transported. The use of two transport devices can be advantageous, particularly with heavy cable drums. Ultimately, this depends on the strength and size of the human transporters, the dimensions and weight of the cable reels, and national health and safety regulations.

Abutment or abutment means within the meaning of the invention that forces are absorbed, with the result that the abutted component is also fixed and secured against unwanted slipping during the transport of a cable reel.

The transport device is provided in particular for transporting a cable drum. The suitability is preferably also extended to lifting and setting down the cable drum. A suitability for lifting, transporting and setting down is then to be understood as transport.

In particular, it is provided that the axis of longitudinal extent of the longitudinal guide body runs at an angle to the main plane of extent of the front disk to be supported. In combination with a translationally displaceable or movable adjusting element, this has the advantage that cable drums with end plates of different thicknesses can be transported. This increases the flexible applicability of the transport device, with safe transport always being provided.

The axis of extension of the hooking web preferably runs parallel to the main plane of extension of the end plate to be supported.

A cable reel usually has a hollow cylinder with an axis of rotation, which has an end disk with an opening at each of its two ends. In particular, the openings of the end disks and the hollow cylinder are arranged coaxially to one another in such a way that the cable drum has a central bore that runs through the two end disks and the hollow cylinder. The openings of the end disks preferably have a smaller radial diameter than the inner diameter of the hollow cylinder.

The cable drum is in particular a cable drum. The cable drum is particularly preferably a cable drum for data lines, in particular for fiber optic cables.

In particular, the adjustment element is a displacement element.

The U-shape design of the hook assembly means that the basic shape resembles the letter "U" of the Latin alphabet. This is to be understood as an approximate description. A U-shape is closely based on a V-shape, with a V-shaped hook arrangement having a smaller load bar, for example. For example, the outer bar, the load bar and the hooking bar can be sequentially in a right angles to each other. This corresponds to an embodiment of a U-shape. It is also possible that the outer bar and the hooking bar each have an obtuse angle to the load bar, this corresponds to a U-shape with a tendency towards a V-shape, which is also to be understood as a U-shape.

Finally, according to one embodiment of the hook arrangement, the load bar can be made so small that in particular the outer bar and the hooking bar act as load-bearing components of the front disk. This corresponds optically to a V-shape, which can also be defined as a U-shape.

According to an advantageous embodiment of the invention, it is provided that the adjusting element is arranged on the longitudinal guide body such that it cannot rotate about the axis of longitudinal extension of the longitudinal guide body by means of a form fit. Positive locking is a simple technical means to ensure that the adjustment element does not rotate relative to the longitudinal guide body and thus a transported cable drum does not loosen from its fixed position with the transport device in the event of accidental jerky movements during transport.

According to an advantageous embodiment of the invention, it is provided that the adjustment element has a guide sleeve which encloses the longitudinal guide body for the translational movement of the adjustment element along the axis of longitudinal extension. This has the advantage that the adjustment element is arranged on the longitudinal guide body so that it cannot be lost. In this way, the adjustment element does not get lost during construction and work safety can always be guaranteed.

According to an advantageous embodiment of the invention, it is provided that the longitudinal guide body has a non-circular cross-section, in particular a square cross-section, in cross-section with respect to its axis of longitudinal extent, and that the adjustment element has a guide sleeve which encloses the longitudinal guide body with a correlating internal hollow cross-section, in particular a square internal hollow cross-section. This is a particularly preferred embodiment and an advantageous example of a form fit. In this way, in particular, a favorable production can be made possible at the same time as well as a secure abutment.

According to an advantageous embodiment of the invention, it is provided that the square cross-section has an edge length of 8 millimeters up to and including 12 millimeters, preferably 10 millimeters inclusive, with the inner square hollow cross-section of the guide sleeve having a respective edge length as internal dimensions for enclosing the square cross-section of 0.5 millimeters inclusive up to and including 3 millimeters, preferably 1 millimeter inclusive, greater than the respective edge length of the square cross-section. The longitudinal guide body is thus held somewhat loosely in the guide sleeve. This has the advantage that the finest dirt particles do not fix the guide sleeve around the longitudinal guide body, so that the conveyor mistakenly assumes a firm abutment. There is a risk that these dirt particles may become loose during transport of the cable drum, the guide sleeve will slip and the cable drum will ultimately fall down due to the impact load. This risk can be reduced by appropriate play.

According to an advantageous embodiment of the invention, it is provided that the contact body is deburred at least on its edges for contact with the front disk, preferably on all edges. This helps to ensure that the contact body does not accidentally tilt with the end plate, with this tilting possibly coming loose during transport of the cable drum, the guide sleeve slipping and the cable drum ultimately falling down due to the impact load. This risk can be reduced by appropriate play.

According to an advantageous embodiment of the invention, it is provided that the guide sleeve is connected to the contact body at least indirectly, in particular via a spacer element, the preferred spacer element being arranged along the longitudinal axis of the longitudinal guide body in the lower quarter of the guide sleeve. The spacer element has the advantage that it increases the flexibility of the transport device. With an angled design of the longitudinal guide body, for example, the increasing distance, which promotes the safety of the transporter, can be compensated for when the transport device is used on thin-walled cable reels. In the case of an angled longitudinal guide body, the low arrangement of the preferred spacer element enables the greatest possible distance from the gripping means during abutment and thus increases the safety of the conveyor.

According to an advantageous embodiment of the invention, it is provided that the transport device has an adjustment element with a contact body, wherein the adjustment element can be moved translationally along the longitudinal axis of the longitudinal guide body in order to support an end disk of the cable drum with the contact body during the transport of the cable drum. It is therefore an advantage that the transport device is a translationally movable adjusting element ment with a plant body. The front disc of the cable reel is thus clamped between the contact body and the hooking bar. In particular, it is provided that a cable drum is transported by two transporters, each with a transport device. The translational displaceability enables flexible application for a large number of different geometries of cable drums. The adjusting element can thus be displaced in such a way that it can be hooked into an opening in a front disk. The adjusting element is then moved in a translatory manner in such a way that there is a transport-safe connection between the transport device and the cable drum. The adjusting element usually fixes itself due to its weight, so that the process takes place in a time-efficient and reliable manner. No separate training is necessary, as the transporter only takes care of hooking and subsequent transport. Furthermore, the translational displaceability of the adjustment element enables flexible applicability with differently dimensioned front disks. For example, it is also possible to avoid projections on an end disk, which would prevent the contact body from bearing evenly, by having the contact body bear against it at a different point. The abutment of the end plate of the cable drum by the contact body takes place in particular oriented to the axis of rotation by form-fitting resistance. Furthermore, a non-positive portion can act oriented to the axis of rotation and vertical to the axis of rotation by the contact body being pressed against the front disk. In order to be able to safely counteract an end plate of the cable reel of any thickness with the contact body during the transport of the cable reel through the transport device, a flexible possibility must be provided for this. This is possible due to the translatory mobility of the adjustment element. The adjusting element is thus to be set in an abutting manner, in particular before transporting, in order to abut the front disk of the cable drum while the cable drum is being transported. The position of the adjustment element along the axis of longitudinal extent of the longitudinal guide body is maintained while the cable drum is being transported.

According to an advantageous embodiment of the invention, it is provided that the adjusting element can be continuously moved in a translatory manner along the axis of longitudinal extension of the longitudinal guide body. The stepless adjustability enables an ideal adaptation to the dimensions and properties of the end plate to be supported. The transport device can be used flexibly and does not have to be designed and selected individually for each cable drum. On the one hand, this reduces the time required for selecting the appropriate transport device and also the costs for several transport devices.

According to an advantageous embodiment of the invention, it is provided that the adjustment element has a guide sleeve which encloses the longitudinal guide body for the translational movement of the adjustment element along the axis of longitudinal extension. It turned out that this is a suitable way to ensure reliable application under harsh environmental conditions. The adjusting element is thus arranged captively on the transport device and is not in danger of being lost either when the transport device is in use or not. There can preferably be play between the longitudinal guide body and the guide sleeve in order to allow the sliding element to fall off more easily due to its weight for abutment.

According to an advantageous embodiment of the invention, it is provided that the guide sleeve is connected to the contact body at least indirectly, in particular via a spacer element. The spacer element has the advantage that it increases the flexibility of the transport device. With an angled design of the longitudinal guide body, for example, the increasing distance, which promotes the safety of the transporter, can be compensated for when the transport device is used on thin-walled cable reels.

According to an advantageous embodiment of the invention, it is provided that the contact body has a contact main extension plane, which is arranged running parallel to the outer web extension axis and/or to the hooking web extension axis. The parallelism enables the front plate to be clamped as securely as possible. In the case of larger deviations from parallelism, it has been found that the clamping of the end plate has play.

According to an advantageous embodiment of the invention, it is provided that the longitudinal guide body has a non-circular cross-section in cross-section with respect to the axis of longitudinal extent for translational and torsion-proof guidance of the adjustment element. In particular, the longitudinal guide body has a square cross-section in cross-section relative to the axis of longitudinal extension. For the purposes of the invention, circular means that a cross section always has the same radius from its outer edge to its center. A non-circular cross section has the advantage that attached elements, for example an adjustment element, can be added in a rotationally fixed manner. Furthermore are ins special circular cross-sections expensive to manufacture.

According to an advantageous embodiment of the invention, it is provided that the translational mobility of the adjustment element along the longitudinal axis of the longitudinal guide body is limited at the transition from the gripping means to the longitudinal guide body. This ensures that the carrier does not suffer any injuries to his fingers if the adjusting element slips up while the cable drum is being transported.

According to an advantageous embodiment of the invention, it is provided that the translational mobility of the adjustment element along the longitudinal axis of the longitudinal guide body is restricted at the transition of the longitudinal guide body to the U-shaped hook arrangement. The deeper the displacement element is arranged, the lower the material thickness of the end plate of the transport device. However, a low material thickness also means that the front disk can be destroyed more quickly. Therefore, the adjusting element is preferably to be secured with a lower stop, so that no further force can act on the front disk, which would act without a lower stop and thus destroy the material of the front disk.

According to an advantageous embodiment of the invention, it is provided that the axis of longitudinal extension of the longitudinal guide body and the axis of extension of the outer web of the outer web are arranged to run at an acute angle to one another. It is advantageous here that the transport device has a longitudinal guide body which, when the transport device is hooked into the cable drum, is arranged in such a way that the gripping means is always at a distance from the cable drum. There is therefore no risk of injury for a human transporter who puts his hand in the gripping means and transports the cable drum. In other words, this means that the cable drum cannot be slipped any further along the axis of rotation and it is thus possible to avoid injuring the hand of the transporter, in particular crushing it. It has been found that the angle between the axis of longitudinal extension of the longitudinal guide body and the axis of extension of the outer web of the outer web is particularly advantageous as an acute angle. An acute angle is an angle that is less than 90 degrees. The angle is preferably less than or equal to 60 degrees, particularly preferably less than or equal to 45 degrees. It should be noted here that the smaller the angle, the more stability there is during transport. A decreasing angle thus increases the transport safety because the transport is less wobbly. On the other hand, as the angle increases, the distance between the gripping means and the cable drum increases, which also increases work safety because there is no risk of impacts or crushing of the hand from a cable drum that wobbles during transport. The final angle can therefore depend on the dimensioning of the cable reel to be transported.

According to an advantageous embodiment of the invention, it is provided that the acute angle is between 15 degrees and 25 degrees inclusive, preferably between 16 degrees and 20 degrees inclusive. This means in particular that the acute angle is between 15 degrees up to and including 16 degrees, between 15 degrees up to and including 20 degrees, between 15 degrees up to and including 25 degrees, between 20 degrees up to and including 25 degrees, between 16 degrees up to and including 20 degrees inclusive, between 16 degrees up to and including 25 degrees inclusive, or between 20 degrees up to and including 25 degrees inclusive. It has been found that these angular ranges are particularly suitable for reducing the risk of injury to carriers during the transport of cable drums and thus increasing work safety. The main load of the cable reel is mainly borne vertically and at the same time it is ensured that the gripping means is spaced from the end sheave of the cable reel during transport.

According to an advantageous embodiment of the invention, it is provided that the hook arrangement is U-shaped in such a way that the hooking bar has an end section so that the end section is arranged pointing in a direction opposite to the weight of the cable drum during transport of the cable drum. This means that the end section is directed upwards during transport of the cable reel. Advantageously, it is therefore provided that the cable drum, due to its own weight, ensures that the end section does not fall out of the respective opening of the cable drum during transport of the cable drum.

According to an advantageous embodiment of the invention, it is provided that the load bar has a load bar extension axis, which is arranged running at a respective angle perpendicular to the outer bar extension axis and/or to the hooking bar extension axis. This means that the U-shape of the hook arrangement is realized insofar as the outer web extension axis and the hooking tab extension axis are arranged parallel to each other and as the load tab extension axis is perpendicular to the outer tab extension axis and the hooking tab extension axis. This ensures a secure abutment of the storage reel while the cable reel is being transported.

According to an advantageous embodiment of the invention, it is provided that the axis of extension of the outer web and the axis of extension of the hook web are arranged so as to run parallel to one another. This ensures a secure abutment of the storage reel while the cable reel is being transported.

According to an advantageous embodiment of the invention, it is provided that the gripping means is designed in particular as a loop grip or as a T-grip and is preferably detachably connected to the longitudinal guide body. A loop handle has an oval contour, with two parallel struts being closed by semicircular elements. The first strut is used to hold it by hand and the second strut is used to connect it to the longitudinal guide body. An embodiment as a loop grip has the advantage that the carrier can thus hold the gripping means on the first, upper strut and has protected the fingers against impact with the cable drum by the lower strut. The T-handle, on the other hand, is cheaper to manufacture.

The optionally preferred detachable connection between the gripping means and the longitudinal guide body is made, for example, by a screw connection or connections with a similar effect. One advantage is that this allows the adjustment element to be replaced. The adjusting element is exposed to an increased risk of material damage due to the permanent stress during transport. It can therefore be advantageous for the adjustment element to be able to be replaced simply by releasing the detachable connection, inserting an alternative adjustment element and closing the detachable connection again. Furthermore, detachable connections are advantageous compared to thermal joints, because they affect the material structure and can thus create weak points.

The ratio of the horizontal width to the vertical height of the contact body between 2:1 and 5:1 is particularly preferred. This ratio is particularly preferably 4:1. It has been found that this is helpful for an even distribution of force during transport of the transport device.

In particular, the transport device is made of a single alloy. This is preferably S235JR+AR (new edition EN 10025-2:2004-10, formerly S235JRG2, even earlier St 37-2, material number 1.0036 to 1.0038, earlier designation according to EU 25-72 also Fe 360 B) or S355J2+N ( new edition EN 10025-2:2004-10, formerly S355J2G3, even earlier St 52-3 N, material number 1.0577 or 1.0570, earlier designation according to EU 25-72 also Fe 510 D1). It has been found that these alloys allow for an inexpensive transport device with good mechanical properties.

The formulation of perpendicular, ie 90 degrees, and parallel in the sense of the invention provides for deviations of less than or equal to 10 degrees, but at least less than or equal to 5 degrees. However, complete parallelism or an exactly perpendicular angle is particularly preferred. However, this may vary due to production.

In particular, it is provided that at least the longitudinal guide body is cut out of sheet metal by means of flame, plasma, laser beam or water jet cutting. This has a stress-relieving effect.

The hook arrangement is preferably connected monolithically to the longitudinal guide body. Monolithic means that the hook arrangement and the longitudinal guide body are manufactured in a common manufacturing step. This has a stress-relieving effect.

For example, the gripping means is connected in one piece to the longitudinal guide body. One-piece means that both parts can be joined together in a separate process, detachable or non-detachable. For example by thermal joining methods. This has the advantage of a fixed connection.

According to an advantageous embodiment of the invention, it is provided that the end section of the hooking web is flat or has a cover, in particular a rubber cover, so as not to damage the hollow cylinder from the inside. Sudden damage to the hollow cylinder from the inside would allow the cable reel to sag and thus increase the risk of injury to the carrier. This is hereby omitted.

According to an advantageous embodiment of the invention, it is provided that the gripping means has a round cross-section for gripping. This makes it easier to grip the gripping means and thus reduces the risk of the grip coming loose during transport of the cable drum, for example wisely through edges that press on your fingers. In particular, it can be provided that the longitudinal guide body has a polygonal cross section. A polygonal cross-section, for example a square cross-section, enables an adjustment element to be arranged in a torsion-proof manner and also has an advantageous flow of forces under loads caused by the weight of the cable reel.

The transport device is used for transporting the cable drum, in particular together with a second transport device, each transport device being hooked individually into an opening of the cable drum by a human transporter. The transporters can thus transport the cable drum with one hand.
