Technical Field

The present invention relates to a coupling device for simultaneously coupling and uncoupling a plurality of coupling member pairs, comprising:

-a plurality of coupling pairs, each coupling pair having a first coupling portion and a second coupling portion;

-a first mounting frame on which the first coupling portions of the plurality of coupling pairs are arranged;

-a second mounting frame arranged parallel to the first mounting frame, wherein the second coupling parts of the plurality of coupling element pairs are arranged to the second mounting frame, and wherein the second mounting frame is movable towards and away from the first mounting frame between a connected position, in which each first coupling part is connected with a corresponding second coupling part, and a disconnected position.

Background

Such coupling devices are typically known from electrical connectors, wherein a plurality of terminals are arranged in a first housing which is inserted into a second housing with corresponding terminals in order to connect the plurality of terminals simultaneously.

If a large number of terminals are to be connected simultaneously, significant force will be required to connect the terminals.

The required force will be even more pronounced to the extent that a person cannot manually generate it if a plurality of hydraulic connections, for example quick connect disconnect couplings or quick disconnect devices (QDC), are to be connected simultaneously.

Particularly when hydraulic couplings are used, it is further desirable that once these couplings are coupled, the hydraulic pressure does not force the coupling parts out of each other to disconnect the coupling.

Disclosure of Invention

It is an object of the present invention to provide a coupling device in which the above-mentioned disadvantages are reduced or even removed.

This object is achieved according to the invention with a coupling device according to the preamble, which is characterized by at least one rack and pinion transmission arranged between the first mounting frame and the second mounting frame, wherein the pinion is arranged on a shaft which is rotatably arranged in the first mounting frame, and wherein the rack extends along the pinion from the second mounting frame into the first mounting frame in the direction of movement of said second mounting frame;

wherein the shaft is extended such that at least one end thereof extends out of the first mounting frame, and wherein the operating lever is arranged on the shaft.

The use of at least one rack and pinion transmission allows a controlled movement of the mounting frame towards the connection position and a high connection force to be generated using the operating lever to rotate the pinion via the shaft. Another advantage of using a rack and pinion transmission is that such transmission can be embodied as self-braking, so that hydraulic pressure exerted on the pair of couplings does not push the mounting frames apart from each other.

Preferably, the gear and the shaft are integrally formed, i.e. as one piece. This avoids any play between the shaft and the gear.

An embodiment of the coupling device according to the invention further comprises guiding means arranged to the first mounting frame and the second mounting frame for guiding the movement between the connected position and the disconnected position.

In a preferred embodiment of the coupling device according to the invention, the guide means comprise at least two guide pins extending from the second mounting frame and at least two corresponding guide holes arranged in the first mounting frame.

At least two guide pins and corresponding guide holes ensure a limited guidance of the two mounting frames.

Preferably, the guiding means are further implemented by the at least one rack and a hole arranged in a first mounting frame in which the corresponding gear wheel extends. The at least one rack may also act as a guide by extending the gear into the bore. The aperture further provides a housing for the rack so that the rack does not bend away from the pinion and large forces can be transferred from the pinion to the rack.

Another embodiment of the coupling device according to the invention further comprises blocking means comprising a hole or groove arranged in the rack and a locking pin movable perpendicular to the movement of the at least one rack between a locking position in which the locking pin engages into the hole or groove and an unlocking position.

The blocking means ensure that the rack is held in place, wherein the pairs of links are connected to each other. The blocking means prevent any movement of the rack in the locking position and thus of the two mounting frames.

Preferably, the free end of the rack is wedge-shaped and the wedge-shape is directed towards the locking pin to compress the locking pin towards the unlocked position.

When the mounting frames are disconnected and moved towards each other, the wedge shaped end of the rack will force the locking pin out, which allows the rack to be inserted into the first mounting frame. The locking pin will only engage with the hole or groove of the rack when the rack is fully inserted and the first mounting frame and the second mounting frame are in the connected position.

In yet another embodiment of the coupling device according to the invention, the at least one gearwheel comprises a toothed sector and a non-toothed sector, wherein the corresponding rack comprises a toothed region and a recess arranged adjacent to the toothed region, wherein the recess coincides with the non-toothed sector of the gearwheel.

The toothed sector of the gear and the toothed region of the rack enable the first mounting frame and the second mounting frame to be moved into the connecting position. Further rotation of the gear causes the non-toothed sector to engage a conforming recess of the rack, thereby providing locking of the rack in the connected position.

Preferably, the coupling device further comprises a blocking means comprising a hole or groove arranged in the shaft and a locking pin movable perpendicular to the shaft between a locking position in which the locking pin engages into the hole or groove and an unlocking position.

The locking pin may be engaged with the shaft such that the gear wheel is no longer rotatable, which ensures that the first mounting frame and the second mounting frame are held in the connected position.

In yet another embodiment of the coupling device according to the invention, the second end of the shaft extends out of the first mounting frame and the second operating lever is arranged on the second end of the shaft.

With such an embodiment, the shaft can be rotated from both ends. If the two levers are connected to each other at the free ends, the operator can provide the maximum force on the shaft.

In yet another embodiment of the coupling device according to the invention, the pair of couplings comprises a hydraulic quick connect disconnect coupling and/or the pair of couplings comprises an electrical connector.

In yet another embodiment of the coupling device according to the invention, the first mounting frame and the second mounting frame are substantially plate-shaped.

Detailed Description

Fig. 1 shows a perspective view of a first embodiment of a coupling device 1 according to the invention. The coupling device 1 has a first mounting frame 2 and a second mounting frame 3, which is arranged parallel to the first mounting frame 2.

A plurality of first coupling portions 4 of hydraulic coupling pairs, such as quick disconnect couplings, are arranged in the first mounting frame 2. The corresponding second coupling parts 5 of the hydraulic link pairs are arranged in the second mounting frame 2.

As shown in detail in fig. 7, the second hydraulic coupling part 4 is mounted in the second mounting frame 3 and locked by a nut 40 which is received in a recess 41 of the second mounting frame 3. By means of the nut 40, the second hydraulic coupling part 4 can be removed for maintenance.

Fig. 10 shows a detail of the first coupling part 4 arranged in the first mounting frame 2. The first coupling part 4 is provided with a semi-circular groove 42 corresponding to a semi-circular groove 43 in the first mounting frame 2. By aligning both the semi-circular grooves 42, 43 to form a full circular groove, the rotation of the first coupling part 4 during maintenance can be locked by inserting a pin into the full circular groove 43, 43.

As shown in fig. 2 and 3, the second mounting frame 3 is provided with a guide pin 6 which is guided in a guide hole 7.

The gear racks 8, 9 are arranged to the second mounting frame 3 and extend into holes 10 in the first mounting frame 2. Gear 11 extends into bore 10. The gear 11 is arranged on a shaft 12 which is operated by levers 13 arranged on both ends of the shaft 12.

As shown in fig. 8, a pin groove 44 is provided to align the rack 8 with the second mounting frame 3. The pin slot 44 is a circular slot in which a cylindrical pin is disposed. Since this slot overlaps between the toothed rack 8 and the second mounting frame 3, the alignment of the toothed rack 8 is ensured.

Fig. 9 shows a detail of the shaft 12. The shaft 12 is provided with a recess 45 into which a spring-loaded pin 46 extends. Due to the spherical end 47 of the pin 46 and the appropriately shaped notch 45, the shaft 12 can be moved out of the locked position by applying an additional, small force. This spring-loaded pin 46 thus provides a recognizable position for the shaft, while providing the ability to freely rotate the shaft and attached lever 13.

A locking pin 14 arranged on a control lever 15 is arranged in the first mounting frame 2 perpendicular to the toothed rack 8. The rack 8 has a toothed portion 16 which cooperates with the gear wheel 11, and a hole or recess 17 in which the locking pin 14 can be located.

Fig. 4 shows the coupling device 1 in the connected position, in which the second mounting frame 3 is moved towards the first mounting frame 2 and is guided by the guide pin 6 and the toothed rack 8 arranged in the hole 10. This movement is caused by the rotation of the shaft 12, which drives the gear 11 and, by engagement on the toothed portion 16, translates the rack 8.

In this connecting position of the first mounting frame 2 and the second mounting frame 3, the locking pin 14 is located in a hole or recess 17 of the toothed rack 8 to prevent the first mounting frame 2 and the second mounting frame 3 from being unintentionally moved towards the disconnected position. When it is desired to rotate the shaft 12 so that the second mounting frame 3 is moved to the disconnected position, the locking pin 14 is pulled out of the slot or groove 17 by the control lever 15, after which the shaft 12 can be rotated and the first mounting frame 2 and the second mounting frame 3 can be moved to the disconnected position.

Fig. 5 shows a cross-sectional view of a second embodiment of a coupling device 20 according to the invention. The coupling device 20 has a first mounting frame 21 and a second mounting frame 22. The first mounting frame 21 and the second mounting frame 22 are guided by the rack 25 and the hole 26.

The rack 25 has a toothed region 27 and a recess 28. The rack 25 cooperates with gears 29, 30 arranged on a shaft 31 operable by a lever (not shown). The gears 29, 30 have a toothed sector 29 and a non-toothed sector 30.

When the shaft 31 is rotated, the teeth of the toothed sector 29 will engage with the toothed region 28 of the toothed rack and pull the second mounting frame 22 towards the first mounting frame 21 and into the connecting position (see fig. 6).

When the first mounting frame 21 and the second mounting frame 22 are in the connecting position, the shaft 31 can be further rotated such that the toothless sector 30 is accommodated in the recess 28 of the rack 25 and it is ensured that the rack 25 cannot be moved without the intentional rotation of the shaft 31 and the gear 29, 30.
