Definitions
- the invention relates to the control of a cable transport installation.
- such an installation comprises a carrying cable tractor forming a closed loop between two stations and means of locomotion fixed on the cable using a tie.
- the means of transport are vehicles formed by a fastener, a line and a receptacle which can be a cabin, a seat, a nacelle or similar. Vehicles are non-clutch.
- the fastener ensures the connection between the vehicle and the cable and more particularly between the vehicle hanger and the cable.
- the hanger is articulated on the body of a fixed jaw that includes the fastener.
- the fixed jaw includes a movable jaw.
- the clamping force is developed directly on the movable jaw.
- the effort is guaranteed by a stack of calibrated spring washers which is supported in a housing which is centered on the fixed jaw.
- Tightening the clip on the cable is done using a nut.
- the actuation of the nut in one direction causes a compressive force on the spring washers and a relaxation of the clamping force of the fastener on the cable.
- the compression force of the spring washers is released and a clamping force of the fastener is applied.
- This type of device allows you to move the clip and modify the tightening force without changing the initial setting.
- the fastener is an important part which must guarantee safety when tightening, non-slip and dynamic stresses.
- the cable is checked using a coil magnetographic and should be done between once every three years and one times a year.
- the cable is moved step by step, each step being associated with the removal of a vehicle. Then we have to move the vehicle to a storage area.
- the cable can be checked by operating the bare cable.
- This check therefore requires at least three turns of cable to be carried out and we are forced to remove and reassemble the vehicles so the fasteners without provided that they can simultaneously carry out other checks requiring disassemble the fasteners.
- the single cable control immobilizes the installation for two to three days.
- the invention therefore proposes to solve the problem mentioned above using of a process allowing in particular to carry out step by step the cable control and simultaneously carry out checks other than the cable check.
- the invention proposes a method for controlling an installation of transport comprising a tractor carrying cable forming a loop between two stations and vehicles fixedly attached to the cable by a clip, in which a control coil is placed on the cable, at least in the direction cable movement, to control the cable passing through the coil.
- the method allows step by step control of the cable and simultaneously controls other than the cable control.
- the setting the implementation of this process is simple and rapid and requires little labor.
- the cable is subdivided into sections corresponding to the distance between two cabins.
- the cable is operated step by step, one step corresponding to the length of a section.
- Such a method can include a step which consists in carrying out a check. magnetography of the cable passing through the coil.
- the invention also relates to a device for controlling an installation of transport comprising a tractor carrying cable forming a loop between two stations and vehicles fixedly attached to the cable by a clip, said control device comprising a control coil on the cable, stationary at least in the direction of the cable, in order to control the cable crossing the coil.
- said device device further comprises a transfer unit capable of separating the fastener of the cable upstream of the coil and a control unit capable of actuating the movement of the cable by a chosen pitch, the transfer unit being able to secure again the cable attachment downstream of the coil, after checking the section of cable associated with said clip.
- the monitoring device may include a slip test unit of the fastener.
- the attachment transfer unit of the control device of a transport may include a sub-unit for detaching the fastener, a cable displacement sub-unit and a securing sub-unit of the fastener.
- FIG. 1 illustrates an embodiment of the control device according to the invention
- FIGS. 2A and 2B illustrate the opening and closing the coil on the cable.
- Reference 1 designates a device for controlling a transport installation 2 intended for passengers, and comprising two stations 3: a departure station and an arrival station.
- Installation 2 comprises a tractor carrying cable 4 forming a loop between the departure station and arrival station.
- the cable 4 is subdivided into sections T, generally of the same length.
- a vehicle 5 comprising a cabin.
- the vehicles 5 can comprise seats.
- a hanger 6 is placed on the roof of the cabin.
- Line 6 extends, in its upper part by a fastener 7 which secures the cable cabin 4.
- the fastener 7 comprises a fixed jaw to which the hanger 6 is fixed and a jaw mobile placed inside the fixed jaw and intended to tighten the cable 4.
- the clamping force on cable 4 is developed directly on the movable jaw of the fastener 7, the adjustment being made using a nut.
- the installation control device 1 For the control of the installation 1, in one of the two stations 3, is the installation control device 1.
- the coil 8 is formed by a circular winding which is in two parts separated by two diametrically opposed generators. Along the first generator, there are means of articulation. Along the second generator, the winding is cut so that it is possible open and close the coil 8.
- the coil 8 is suspended on the fixed structure of one of the two stations 3.
- the movement of the cable 3 is actuated until a first fastener 7 is found in the decoupling sub-unit 11.
- a first section T1 is defined from the location of the coil 8.
- the clip 7 is then removed.
- the vehicle 5 is separated from the cable 4 and the cable 4 is bare over the length of the section T1.
- the fasteners 7 being spaced from each other by a distance equal to the length of section T1, a second fastener 7 is located in the sub-unit separation 11.
- the cable location 4 corresponding to the first fastener 7 is located at the level of the joining sub-unit 12.
- the first fastener 7 is then again secured to it with the cable 4.
- the clamping force is reduced clip 7 on cable 4 until it can slide on cable 4.
- the operation is repeated until the entire cable 3 is checked.
- the unit 11 for sliding the fasteners 7 is placed before the fastener transfer unit 10 7. It can be placed after, which is particularly the case in the second embodiment for which, it is normal to check the non-slip after the fastener has was united again.
- a tool 14 is used, such as a safe, which allows the jaw to be applied to the fastener 7, as close as possible to the axis of the cable 3 the force parallel to it.
- the control device 1 is fully automated.
- control device is entirely or partly manual.
- the different units 9, 10, 11, 12, 13 can be placed in a different order along the cable and work separately. This allows in particular to be able to perform only one type of control when it is not necessary to carry out several.
