Description

[0001] The invention relates to a cable plough system.

[0002] Such cable plough systems comprise a cable plough for inserting at least one line, in particular a pipe or cable, into the ground and a chassis, wherein the cable plough comprises at least one laying unit, wherein the or each laying unit has a blade suitable for engaging the ground to form an earth channel and a cable guide for inserting the line into the earth channel formed or formable by the blade, wherein the chassis comprises a driver's cab and front wheels and rear wheels, wherein the front wheels and / or the rear wheels are each attached to the driver's cab by means of a support, wherein the cable plough system has a coupling device, wherein the chassis and the cable plough can be or are connected to one another in an interchangeable manner by means of the coupling device, and wherein the coupling device is or comprises at least one eyelet-bolt connection.

[0003] The driver's position is not only understood as the standing or sitting position of a driver, but as the entire central body of the chassis to which the front and / or rear wheels are movably attached via their respective supports.

[0004] For the state of the art, reference is made to DE 17 73 060 U, FR 646 560 A, DE 10 2016 111 012 A1, DE 26 41 309 A1, DE 10 2016 106 506 A1, US 2006 / 0 266 533 A1, US 7 841 802 B2, EP 1 167 636 A1, DE 16 40 643 B and DE 10 2014 113 831 B3.

[0005] A disadvantage of existing cable plow systems is that transporting the cable plow and chassis to the site is extremely complex. The cable plow system must be loaded onto heavy-duty transporters using cranes, possibly after a laborious separation of the chassis from the cable plow. The cable plow system or its components must then be unloaded at the site using cranes, reassembled (sometimes laboriously), and placed in the operational position, for example, in a launch pit.

[0006] There is therefore a need for a way to easily and quickly separate the cable plough from the chassis and reconnect the two units later. Furthermore, there is a need for a way to load the cable plough without the need for additional equipment, such as heavy-duty cranes.

[0007] It is therefore an object of the invention to provide a new cable plough system, in particular a new cable plough system which enables simple and quick coupling or uncoupling of the cable plough and the chassis.

[0008] This object is achieved by a cable plough system having the features of claim 1. Advantageous embodiments and further developments are specified in the respective dependent claims.

[0009] The cable plough according to the invention is characterized in that the or each eyelet-bolt connection comprises at least one holding means with a first eyelet and at least one fork with two pins, each pin having a second eyelet, wherein the holding means is receivable or received between the two pins of the fork, so that the first eyelet and the two second eyes form a common through-opening, and wherein the or each eyelet-bolt connection comprises at least one bolt, wherein the bolt for connecting the chassis and the cable plough is guided or guided into or through the through-opening, wherein the chassis has a carriage and the cable plough has a carriage receptacle, wherein the carriage for connecting the chassis to the cable plough is precisely receivable or received in the carriage receptacle by the carriage being or being driven through the chassis into the carriage receptacle,wherein the carriage of the chassis received in the carriage receptacle of the cable plough centers or positions the cable plough on the chassis in such a way that the holding means of the or each eyelet-bolt connection is or will be arranged between the pins of the associated fork.,

[0010] A key advantage of the invention is that the cable plough can be easily and quickly detached from and reconnected to the chassis. This allows the chassis to be used for other purposes, for example, in conjunction with an alternative cable plough, a trench cutter, or a cable drum transporter, making it extremely versatile.

[0011] Furthermore, the cable plow and chassis can be easily transported separately to and from the job site. The cable plow can also be loaded onto and unloaded from a transporter through the chassis without the need for additional equipment such as heavy-duty cranes. The chassis itself can also be loaded and unloaded without any such additional equipment.

[0012] A further advantage of the invention is that the cable plough connected to the chassis can be optimally controlled during operation by the chassis, particularly through the adjustable outriggers. Furthermore, the chassis prevents the cable plough from tipping during operation.

[0013] The chassis is preferably self-propelled, wherein the chassis in particular comprises an engine.

[0014] The chassis preferably comprises two front wheels and two rear wheels. The outriggers are preferably designed as double arms.

[0015] Preferably, two or more eyelet-bolt connections are provided.

[0016] It can be provided that the first eyelet is arranged on the cable plough and the second eyelets are arranged on the driver's cab, wherein the cable plough and the chassis can be connected or are connected by means of the bolt guided through the first eyelet and the second eyelets.

[0017] The holding device can be mounted on the cable plough and the fork on the chassis. Alternatively, the fork can be mounted on the cable plough and the holding device on the chassis.

[0018] Preferably, the bolt of the or each eyelet-bolt connection is arranged, in particular hydraulically, extendable on the driver's cab, in particular on the underside or in a lower region of the driver's cab, or on the cable plough, in particular on the top side or in an upper region of the cable plough, and can be moved into the through opening for connection to the corresponding first and second eyelets.

[0019] According to a further development of the invention, each support has a lateral adjustment device for adjusting the angle of inclination of the support in relation to a designated direction of travel. With the lateral adjustment devices, the supports can be moved, in particular, in a substantially horizontal plane. For example, the cable plough system can be made narrower (as viewed in the direction of travel) by pulling the supports towards the driver's cab and wider (as viewed in the direction of travel) by pushing the supports away from the driver's cab. It is also possible, for example, to pull the supports towards the driver's cab on one side and extend them on the other side, as viewed in the direction of travel, in order to plough close to an obstacle or boundary.

[0020] The lateral adjustment device may be pneumatically and / or mechanically and / or hydraulically adjustable. Preferably, the lateral adjustment device is hydraulically adjustable, with the lateral adjustment device comprising a hydraulic cylinder arranged between the support and the driver's cab.

[0021] According to one embodiment of the invention, each outrigger has a height adjustment device for adjusting the angle of inclination of the outrigger relative to the ground surface. The height adjustment devices allow the outriggers to be moved, in particular, in a substantially vertical plane. For example, if all outriggers are lowered, the driver's platform is raised accordingly, and vice versa. By adjusting the outrigger heights to different heights, uneven terrain can also be compensated for if necessary.

[0022] The height adjustment device can be pneumatically and / or mechanically and / or hydraulically adjustable. Preferably, the height adjustment device is hydraulically adjustable, with the height adjustment device in particular comprising a hydraulic cylinder arranged between the support and the driver's cab.

[0023] A preferred embodiment of the invention provides that the driver's stand can be raised by means of the height adjustment devices of the supports relative to the ground surface by a height which is greater than the height of the cable plough, so that the driver's stand can be moved or driven over the cable plough to connect the cable plough and the chassis.

[0024] A cable plough connected to the chassis can also be raised using the height adjustment device.

[0025] Furthermore, it can be provided that the holding means of the or each eyelet-bolt connection is arranged on the upper side or in an upper region of the cable plough and the fork of the or each eyelet-bolt connection is arranged on the underside or in a lower region of the driver's cab of the chassis, so that the or each holding means can be connected to the or a corresponding fork by means of the bolt when the driver's cab has driven over the cable plough.

[0026] It may be provided that the fork of the or each eyelet-bolt connection is arranged in a front area of the driver's cab in the intended direction of travel.

[0027] The carriage is preferably arranged at the front of the chassis in a designated direction of travel.

[0028] It is particularly preferred that the cable plough comprises two or more, preferably three, laying units.

[0029] It can be provided that a number of cable guide extensions corresponding to the number of laying units of the cable plough is arranged on the chassis, wherein the cable guide extensions are adjacent to the cable guides of the laying units when the chassis and cable plough are connected, so that the cable guides are extended by the cable guide extension.
