Description

Title of the invention: System for fixing a tool to equipment located at height

[0001] The field of the invention is that of the design and manufacture of railway maintenance equipment.

[0002] The invention relates more particularly to a technique for fixing a tool by screwing onto equipment located at height, in particular equipment on a catenary.

[0003] In the field of railway maintenance, it is necessary to intervene on equipment located at the height of catenaries.

[0004] Intervention on a catenary involves two problems: - an intervention on an element located at height; - an intervention on an electrified track.

[0005] A catenary is a set of mechanical connections requiring proportional tightening adapted to the terrain.

[0006] Railway catenary equipment, which is located at height, needs to be perfectly fixed to ensure correct operation and operational safety.

[0007] Installing tools on equipment located high up on a catenary may involve fixing using screws.

[0008] In this case, it is necessary to tighten the screw used to fix the tool to the equipment to a predetermined torque. Indeed, the various bolted elements of a catenary mechanical connection are subject to strong vibration, environmental and accessibility constraints, and consequently must be tightened to a standardized and suitable intensity and torque.

[0009] Railway infrastructure maintenance workers can only easily access these areas with ladders or motorized lifting equipment suitable for working at height. The maintenance or installation operation necessarily requires suitable equipment, in particular a torque screwdriver, as well as equipment to secure the maintenance worker, on the ladder or in the lifting equipment, who must carry the tool to be fixed and operate the screwdriver.

[0010] Such intervention at height on a catenary necessarily involves disconnecting the power to the site.

[0011] Indeed, the very high voltages implemented on a catenary prevent the intervention of a maintenance agent directly at the level of a catenary.

[0012] The invention aims in particular to overcome these drawbacks of the art prior.

[0013] More specifically, the invention aims to propose a technique for simplifying an installation or maintenance intervention on a tool fixed using a screw to equipment at the height of a catenary.

[0014] The invention also aims to provide such a technique which makes it possible to avoid using a ladder or an authorized lifting device to carry out the intervention.

[0015] The invention also aims to provide such a technique which avoids having to de-energize the catenary on which the intervention is carried out.

[0016] These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which has as its subject a system for fixing a tool on equipment located at height, comprising: - a module to be fixed comprising a screw to be screwed to cause the fixing of the module on the equipment, the tool being intended to be presented by the module; - a screwdriver comprising a socket complementary to the screw; characterized in that it also comprises: - a pole having at one end a grip handle and at the other end a frame on which the screwdriver is intended to be mounted; - means for remote actuation of the screwdriver; - a module support adapter, the support adapter being intended to be mounted on the frame; - means for removably coupling the module to the support adapter, the support adapter being capable of carrying the module in a coupled position of the module to the support adapter, the screw of the module being engaged in the socket of the screwdriver in the coupled position of the module to the support adapter.

[0017] Thanks to the system according to the invention, it is possible for an operator to fix a tool to equipment at height, in particular a railway catenary, without having to use a lifting device to climb to the level of the equipment, or a ladder.

[0018] The operator can simply use the pole to intervene and fix from the ground his module which presents the tool. To this end, the operator must mount the support adapter on the frame, then place the module on the support adapter by coupling it. The removable coupling means make it possible to position the module on the support adapter, so that the latter temporarily carries the module during installation or intervention. The operator then manipulates the pole to bring the module to the level of the equipment on which it is to be installed. Subsequently, he uses the remote actuation means to trigger the screwing by the screwdriver. Once the module is fixed by means of screwing, the operator simply has to uncouple the module from the adapter.

[0019] Advantageously, the pole is an electrically insulating pole.

[0020] In this way, the system allows intervention on catenaries which would still be supplied with electricity. Such a system facilitates intervention by operators on a railway line because it is not necessary to de-energize the entire site.

[0021] According to a preferred characteristic, the module comprises a passage for receiving a cable intended to form the equipment located at height, the cable being capable of being held captive in the receiving passage during tightening of the screw.

[0022] During installation, it is then sufficient to manipulate the pole so that the cable on which the tool and thus the module are to be fixed is housed inside the receiving passage. A screwing makes it possible to keep the cable captive in the receiving passage of the module, and the module can then be uncoupled from the adapter.

[0023] According to a preferred solution, the module comprises two jaws, at least one of which is movable relative to the other thanks to the screw.

[0024] This solution is particularly simple to implement, and the tightening results in fixing the module along the cable thanks to the closing of the jaw formed by the two dead on the cable.

[0025] According to a preferred design, the module comprises a passage for inserting a cable into the receiving passage, the insertion passage extending in a flared manner from the receiving passage to an opening.

[0026] Thanks to this design, it is easier to insert the cable into the receiving passage by means of manipulation from the ground using the pole. In fact, the operator is located several meters below the cable. Consequently, the insertion passage which extends by flaring allows for pre-guiding of the cable to the receiving passage, and to prevent poor alignment of the cable with the receiving passage from preventing insertion of the cable into the receiving passage.

[0027] According to an advantageous embodiment, the removable coupling means comprise: - at least one carrier axis presented by one of the support adapter and the module, the carrier axis extending parallel to a screwing axis of the screw in the coupled configuration of the module on the support adapter; - a receiving member for the or each carrier axis, the receiving member being presented by the other of the support adapter and the module, the carrier axis being slid into the receiving member in the coupled configuration of the module on the support adapter.

[0028] The coupling, and the stopping of the coupling of the module with the support adapter, are thus achieved quite simply by means of a sliding of the carrier axis(es) in the receiving member(s).

[0029] Preferably, the or each receiving member comprises a flared engagement opening of the carrier axis in the receiving member.

[0030] In this way, an operation aimed at intervening on a module already fixed at height is carried out more easily because the flared engagement opening allows pre-guiding of the carrier axis to bring it into the receiving member.

[0031] Advantageously, the removable coupling means comprise at least one member for holding the module in its coupled configuration with the support adapter, the holding means exerting a predetermined force tending to hold the module in its coupled configuration.

[0032] This prevents unwanted stopping of the coupling of the module with the support adapter.

[0033] Preferably, the holding member is formed by a magnet.

[0034] In this way, the holding member(s) exert a force tending to keep the module in the coupling position on the support adapter. Once the module has been fixed to the overhead equipment, it is sufficient to move the pole so as to extract the supporting axis(es) from the receiving member(s) by exerting a force greater than that exerted by the holding member(s).

[0035] According to an advantageous solution, the remote actuation means comprise an actuation handle located in the immediate vicinity of the gripping handle, the actuation handle being coupled to the screwdriver by means of a link.

[0036] Such a solution is particularly reliable and simple to implement.

[0037] Preferably, in the case where the pole is an electrically insulating pole, the link incorporates at least one electrically insulating section.

[0038] The use of the pole and the actuation means are then perfectly secure to allow intervention on a site still supplied with electricity.

[0039] Preferably, the pole is telescopic, the remote actuation means comprising a reel configured to store a surplus of the link.

[0041] With reference to Figures 1 to 11, a fixing system according to the invention is described below. The fixing system allows in particular the fixing of a tool on equipment 11 located at height.

[0042] According to the present embodiment, the equipment 11 is a cable.

[0043] More precisely, the equipment 11 located at height is railway catenary equipment. The equipment 11 can thus correspond to a cable for tensioning a catenary, for example a cable of a tensioning device with pulley blocks which can extend in an essentially vertical direction, or transversely a vertical axis.

[0044] As illustrated in [Fig. 1], the system comprises: - a 20 screwdriver; - a pole 30 having at one end a gripping handle 301 and at another end a frame 302 on which the screwdriver 20 is mounted; - means 40 for remotely actuating the screwdriver 20.

[0045] With reference to Figures 7 to 9, the system further comprises: - a module 10 to be fixed on the equipment 11, the tool being presented by the module 10; - a support adapter 50 of the module 10, the support adapter 50 being intended to be mounted on the frame 302; - means for removable coupling of the module 10 to the support adapter 50.

[0046] As detailed below, the support adapter 50 carries the module 10 in a coupled position of the module 10 on the support adapter 50. This coupled position is notably illustrated by figures 7 to 9.

[0047] With reference to Figures 7 to 11, a module 10 to be fixed is described below.

[0048] The module 10 to be fixed comprises a screw 101 to be screwed to cause the fixing of the module 10 on equipment 11.

[0049] The module 10 shown has a tool which forms a target intended to be fixed along a cable in order to be able to carry out a measurement, for example by pointing a laser rangefinder at the target.

[0050] For this purpose, the module 10 has a target body 100 forming the tool.

[0051] This target body 100 has an essentially disc shape.

[0052] The target body 100 has notches on its peripheral periphery.

[0053] One of these notches extends to the center of the target body 100.

[0054] Indeed, the module 10 comprises a receiving passage 102 for a cable intended to form the equipment 11 located at height. This receiving passage 102 is formed by the part of the notch at the center of the target body 100.

[0055] The module is then configured so that tightening the screw 101 allows the module 10 to be fixed by means of tightening the module 10 on the cable housed in the receiving passage 102.

[0056] The cable is thus capable of being held captive in the receiving passage 102 when the screw 101 is tightened.

[0057] For this purpose, the module 10 comprises two jaws 104, at least one of which is movable relative to the other thanks to the screw 101.

[0058] More specifically, one of the jaws 104 is secured to the target body 100, while the other of the jaws 104 is mounted to move in translation relative to the target body 100, and is driven in translation by screwing or unscrewing the screw 101.

[0059] The module 10 also comprises an insertion passage 103 for a cable in the reception passage 102.

[0060] This insertion passage 103 extends by flaring from the receiving passage 102 to an opening 105.

[0061] The insertion passage 103 is thus formed by the notch, the part of which in the center of the target body forms the receiving passage 102.

[0062] The insertion passage 103 essentially delimits a triangle section making it easier to guide a cable to the receiving passage 102.

[0063] The module 10 also comprises a block 106. This block 106 is fixed on the target body 100. The block 106 has a tapped hole inside which the screw 101 is screwed.

[0064] Screwing or unscrewing the screw 101 causes the screw to move inside the block 106.

[0065] As detailed below in relation to the removable coupling means, the block 106 has two guide grooves 1061 on two lateral faces opposite each other with respect to the block 106.

[0066] According to the present embodiment, the screw 101 has a hexagonal head.

[0067] At the end of the screw 101 opposite its head, the jaw 104, which is movable in translation, is coupled to the screw 101 so that screwing or unscrewing the screw 101 causes the jaw 104 to move along its translation axis.

[0068] As also detailed below in relation to the removable coupling means, the module 10 comprises two stops 107. Each stop 107 is fixed to the target core 100.

[0069] These stops 107 are each positioned in the extension of one of the two guide grooves 1061.

[0070] With reference to Figures 1 to 3, the screwdriver 20 is described below.

[0071] The screwdriver 20 is an electric screwdriver. This screwdriver 20 is more specifically a portable electric screwdriver.

[0072] The screwdriver 20 comprises: - an electric battery; - an electric motor powered by the electric battery; - a trigger 203 for activating the electric motor; - means for adjusting a tightening torque; - means for selecting a direction of rotation; - a head 202 forming an angle transmission, and - a 201 socket.

[0073] Of course, the socket can be interchanged with other sockets depending on the head of the screw intended to be screwed or unscrewed using the screwdriver 20.

[0074] In the coupled position of the module 10 on the support adapter 50, the screw 101 of the module 10 is engaged in the socket 201 of the screwdriver 20.

[0075] Consequently, in the coupled position of the module 10 on the support adapter 50, actuation of the trigger 203 makes it possible to cause the screw 101 to be screwed or unscrewed.

[0076] With reference to Figures 1 to 4, the pole 30 is described below.

[0077] The pole 30 extends longitudinally between two ends.

[0078] As mentioned previously, the pole 30 has a gripping handle 301 which is located at one of its ends. This gripping handle 301 is intended to be held by an operator wishing to manipulate the pole 30.

[0079] The frame 302 mentioned above is fixed to the other end of the pole 30. This frame 302 makes it possible to mount the screwdriver 20 on this end of the pole 30 as detailed below.

[0080] According to the present embodiment, the pole 30 is a telescopic pole. For this purpose, the pole 30 comprises a plurality of tubular sections fitted together. in the others, and may be either in a retracted position in which the pole 30 has a reduced length, or be in a deployed position in which the pole 30 has a length greater than that presented in its retracted position.

[0081] However, according to another possible embodiment, the pole 30 could not be telescopic.

[0082] According to the present embodiment, the pole 30 is an electrically insulated pole. Indeed, at least one of its tubular sections is made of an electrically insulating material capable of withstanding very high voltages.

[0083] It is also conceivable, as another embodiment, that the pole 30 is not electrically insulated.

[0084] With reference to Figures 2 and 3, the frame 302 is described below.

[0085] The frame 302 comprises: - an upper caliper 3021; - an intermediate stirrup 3022; - a lower caliper 3023; - two 3025 connecting tubes.

[0086] The two connecting tubes 3025 are assembled at one of their ends to the upper stirrup 3021, and at the other of their ends to the lower stirrup 3023. Consequently, the two connecting tubes 3025 extend from the upper stirrup 3021 to the lower stirrup 3023. The intermediate stirrup 3022 is assembled on the two connecting tubes 3025 between the upper stirrup 3021 and the lower stirrup 3023.

[0087] The upper bracket 3021 and the lower bracket 3023 are designed to partially encase the screwdriver 20 and to hold it in a predefined position relative to the frame 302.

[0088] As detailed below, the upper bracket 3021 has two holes 3029 for association with the support adapter 50.

[0089] The upper stirrup 3021 is secured to the end of the pole 30. For this purpose, the pole 30 comprises a coupling end piece 3026 complementary to a coupling member 3028 presented by the upper stirrup 3021, and the frame 302 has a coupling ring 3027 whose tightening on a thread presented on the outside of the coupling member 3028 makes it possible to secure the coupling end piece 3026 inserted in the coupling member 3028.

[0090] The lower stirrup 3023 has a coupling ring 3024 intended to clip along the pole 30 in a manner complementary to the technical means making it possible to secure the upper stirrup 3021 to the end of the pole 30.

[0091] As detailed below, the intermediate stirrup 3022 is used to implement the remote actuation means 40.

[0092] With reference to Figures 1, 3, and 4, the remote actuation means 40 are described below.

[0093] According to the present illustrated embodiment, the remote actuation means 40 comprise: - an actuating handle 41 located in the immediate vicinity of the gripping handle 301; - a link 42 coupling the actuating handle 41 to the screwdriver 20.

[0094] The remote actuation means 40 also comprise an eccentric 44 mounted to rotate on the intermediate stirrup 3022 around an axis of rotation 440.

[0095] Pulling the link 42 towards the gripping handle 301 causes the eccentric 44 to rotate so that it presses the trigger 203 of the screwdriver 20 to actuate it.

[0096] The trigger 203 comprises elastic return means in a spaced position. Consequently, a release of the link 42 causes the trigger 203 to return to its spaced position and thus stops the actuation of the screwdriver 20.

[0097] The remote actuation means 40 also comprise a pull handle 41 secured to the link 42, and intended to be in the immediate vicinity of the gripping handle 301.

[0098] The remote actuation means 40 also comprise a reel 43 configured to store a surplus of the link 42. This reel 43 is particularly useful in the case where the pole is telescopic.

[0099] The reel 43 is secured to the pole 30 using securing means 430.

[0100] As seen in [Fig.l], the remote actuation means 40 also comprise an electrically insulated section 45 which is formed by a rod made of an electrically insulating material.

[0101] This electrically insulated section 45 is coupled to the link 42 at its two ends by means of coupling members 46.

[0102] With reference to Figures 5 to 9, two embodiments of a support adapter 50 are described below.

[0103] The support adapter 50 illustrated by Figures 5 to 8 is designed to allow the attachment of a module to a cable which would extend essentially parallel to the longitudinal axis of the pole 30, and the support adapter 50 illustrated by [Fig.9] is designed to allow the attachment of a module to a cable which would extend essentially orthogonally to the longitudinal axis of the pole 30.

[0104] The support adapter 50 comprises at least one intermediate body, including a first intermediate body 501 which is unique with reference to the embodiment illustrated by FIGS. 5 to 8, and a second intermediate body 502 associated with the first intermediate body 501 with reference to the embodiment illustrated by [Fig.9].

[0105] The support adapter 50 also comprises at least one first rod 503 and at least one second rod 504.

[0106] As detailed below, the second rod(s) 504 form the carrying axis(es) 601 of the removable coupling means.

[0107] According to the two embodiments illustrated, the support adapter 50 comprises in this case two first rods 503 and two second rods 504.

[0108] The first rod(s) 503 and the second rod(s) 504 are integral with the intermediate body(ies).

[0109] Various means can be used to secure these rods to the intermediate bodies.

[0110] With reference to the embodiment illustrated by figures 5 to 8, the first rods 503 and the second rods 504 may have an end provided with a thread complementary to a tapping presented by the first intermediate body 501.

[0111] Alternatively, the first rods 503 and the second rods 504 may simply be inserted into a through hole or a blind hole of the intermediate body(ies), and screws may be used to exert pressure transversely to the rods at the intermediate body.

[0112] The first rods 503 are used to secure the intermediate body(ies) to the frame 302.

[0113] More precisely, the end of the first rods 503 which is opposite that secured to the first intermediate body 501, is inserted and secured in the association holes 3029 of the upper stirrup 3021.

[0114] The intermediate body or bodies are designed to position the second rods 504 according to a predetermined position and orientation relative to the screwdriver 20.

[0115] The intermediate body or bodies are in particular designed so that the second rods 504 extend parallel to a screwing axis defined by the socket 101 of the screwdriver 20.

[0116] With reference to Figures 5 to 11, the removable coupling means are described below.

[0117] As mentioned previously, the module 10 comprises two stops 107, and the second rods 504 form the carrying axes 601 of the removable coupling means.

[0118] Indeed, the removable coupling means comprise: - at least one carrier axis 601, and in this case two carrier axes 601 which, according to the present embodiment, are presented by the support adapter 50; - a receiving member 611 for each carrier axis 601, the receiving member 611 being presented by the module 10.

[0119] According to another conceivable embodiment, the carrier axis(es) 601 could be presented by the module 10 while the receiving member(s) 611 could be presented by the support adapter 50.

[0120] The removable coupling means are configured so that each carrier axis 601 can slide in the receiving member 611 associated with it.

[0121] The receiving members 611 are formed by the stops 607 of the module 10.

[0122] The receiving members 611 each comprise an engagement opening 612 flare of the carrier axis 601 in the receiving member 611.

[0123] In other words, the receiving members 611 comprise a housing intended to accommodate the end of a carrier axis 601, and this housing has a truncated cone shape widening towards the opening of the housing.

[0124] In addition, the removable coupling means comprise at least one holding member 62 of the module 10 in its configuration coupled with the support adapter 50.

[0125] In this case, the removable coupling means comprise two holding members 62. These holding members 62 are each formed by a magnet.

[0126] These holding members 62 take the form of tips coupled to the end of the carrier axes 601. The receiving members 611 are then at least partially made of a material capable of cooperating by magnetism with the holding members 62.

[0127] The receiving members 611 may for example comprise, at the bottom of the housing intended to accommodate the end of a carrier axis 601, a plate made of a material capable of being attracted by a magnet.

[0128] It is also conceivable that the receiving members 611 each integrate a magnet oriented in a manner complementary to the magnets of the holding members 62.

[0129] When coupling a module 10 to the support adapter 50 mounted on the frame and associated with the screwdriver 20, the support adapter 50 and / or the module 10 are manipulated so that the carrier axes 601 align with the receiving members 611.

[0130] The carrier axes 601 are then advanced towards the receiving members 611.

[0131] Initially, the carrier axes 601 will cooperate and be guided by the guide grooves 1061 presented by the block 106 of the module 10.

[0132] By advancing the support adapter 50 towards the module 10, the carrier axes 601 will come into contact with the receiving members 611 and there again be guided thanks to the flared openings presented by these receiving members 611.

[0133] In the final phase of the coupling, the carrier axes 601 come into abutment against the bottom of the housings of the receiving members 611, and the holding members 62 will then exert a force tending to keep the support adapter 50 coupled with the module 10.

[0134] In the coupled position reached by the module 10 on the support adapter 50, the screw 101 of the module 10 is also engaged in the socket 201 of the screwdriver 20. In consequently, at this stage, an actuation of the screwdriver 20 produces the screwing or unscrewing of the screw 101.

[0135] Of course, prior to the installation of a module 10 on equipment at height, the screw 101 is in an unscrewed state but mounted on the module 10.

[0136] When installing a module 10, an operator can manipulate the pole 30 to bring the module 10 into close proximity to the equipment on which it is to be installed.

[0137] According to the present illustrated embodiments, the operator must manipulate the pole so that the module comes to position itself on the cable forming the equipment at height. More precisely, the progression of the module 10 relative to the cable is guided by the insertion passage 103 which is flared to allow the cable to be housed in the receiving passage 102.

[0138] At this stage, the operator can pull the link 42 of the remote actuation means 40 so that the eccentric 44 exerts pressure on the trigger 203 to cause the screw 101 to be screwed in.

[0139] Screwing the screw 101 causes the jaws 104 to tighten on the cable. The module 10, and thus the tool, are then fixed to the equipment at height.

[0140] The operator then simply has to manipulate the pole 30 so as to pull the support adapter 50 backwards relative to the module 10, with sufficient force to counteract that of the holding members 62.

[0141] The system according to the invention makes it possible to fix, or remove a tool from equipment located at height, for example from a railway catenary. This system makes it possible to do this without lifting equipment, or without equipment allowing one to climb to a height.
