In contrast, the sort of circuit for the description in above-mentioned preamble, the installation or removal operation of above-mentioned coaster is not too gratifying, specifically, this is because it is difficult to the free end of outside listrium with respect to the free end of central listrium separately, this then is necessary for two trolley wires of installation or removal, and two outside attachment can only be separated from each other the free end of two outside listriums.This will cause such situation: in some zone of circuit, in the time a trolley wire in two trolley wires need being installed or unclamped, just have some difficulties between the central listrium of one or more mounting and dismounting bodies and cooresponding outside listrium.

Summary of the invention

The objective of the invention is to overcome this defective, for this purpose, the present invention proposes a kind of coaster that is used to carry out Assembly ﹠Disassembly, it is according to above-mentioned coaster design-calculated, but it also has some characteristics so in addition: it comprises central attachment that are arranged on the underframe, these parts are arranged along described longitudinal plane, and at least can be on away from the direction of described longitudinal plane and the free end of central listrium be bonded between cooresponding two antelabium, antelabium is positioned at the both sides on plane, feature of the present invention also is: away from the mounting and dismounting body pedestal, and be parallel on the direction of described longitudinal plane, the ejection parts are as a strut member of two trolley wires.

It will be appreciated by those skilled in the art that: thus by mechanical connecting device its underframe is connected to be placed to this coaster on the mounting and dismounting body on the mounting and dismounting body after, can make this coaster along mounting and dismounting body or suitable be arranged in one row a plurality of mounting and dismounting bodies advance, in this advances process, utilize outside attachment on away from the free-ended direction of central listrium on each mounting and dismounting body the free end of outside listrium in turn apply traction force, thereby make the antelabium of two outside listriums separate in the part with the corresponding antelabium of central listrium, with this understanding, if already installed lead is split out from circuit, the antelabium that then separates just allows cooresponding trolley wire is split out, perhaps, such state also allows cooresponding trolley wire to be inserted into a mounting and dismounting body or to be arranged in a plurality of mounting and dismounting bodies of row, and can position the pushing tow parts, make the degree of separation of mounting and dismounting body be enough to allow trolley wire to be deviate from between the antelabium, perhaps make the holder of pushing tow parts trolley wire, so that it is arranged between the antelabium, pushing tow parts position is suitable for making antelabium to be connected in the cooresponding groove.

Those of ordinary skills also easily understand: after coaster passed through, the elasticity of outside listrium will impel it to return to such shape: under this state, snap in the cooresponding groove by making antelabium, and be fixed in trolley wire between the antelabium.

Therefore, different with the coaster of describing in the above-mentioned european patent application, the free end that can control two outside listriums according to coaster of the present invention is with respect to the free-ended position of central listrium, thereby, just can be in any zone of circuit, trolley wire is engaged with corresponding outside listrium and central listrium, or break away from them.

The device that attachment move outside being used for making lays respectively at the both sides of the vertical symmetry plane of underframe, they can act on simultaneously, make two outside attachment on away from the direction of described longitudinal plane, move, that is to say, away from central attachment, with this with the free end of two outside listriums synchronously away from the free end of central listrium, thereby two trolley wires of installation or removal simultaneously, for according to above-mentioned european patent application design-calculated coaster, control with the method that distinguishing characteristics of the present invention provides, also can finish the work of above-mentioned form.

But, in the case, when this existing coaster is used on the circuit with two trolley wires, another defective can occur, that is to say: for example under situation that another trolley wire of damage then remains intact has appearred in trolley wire, in order to change the trolley wire of damage, it will be pulled down, and also another trolley wire in working order will be split out simultaneously, thereby make circuit quit work, till the trolley wire of having reinstalled trolley wire in working order and replacing again.

Like this, obviously: have at circuit under the situation of two trolley wires, to originate uniquely the elastic deflection precompressed with outside listrium of the grip of trolley wire between lateral border plate free end and central listrium free end, a trolley wire that lacks wherein will seriously influence the ability that mounting and dismounting body keeps another trolley wire in mounting and dismounting body.

Based on such fact, another object of the present invention is to realize a kind of possibility, this possibility does well out of according to pulley structure of the present invention, this possibility promptly is: in the time of in being used in the circuit with two trolley wires, may command outside listrium free end is with respect to the free-ended position of central listrium, thereby can eliminate existing another defective of above-mentioned european patent application.

28,29 has formed the shape of an antelabium or clasp 32, and antelabium or clasp 32 deviations are to the direction away from plane 3, and its shape and size are standard values, so that snap fit onto in the corresponding groove 11 on two leads 7.

Towards below the position on---that is to say farthest at distance pedestal 13, two surfaces 29 are connected on two longitudinal planes 30 on listrium 18 free ends 20, surface 30 extends upward from its connecting portion with surface 29, thereby two surfaces 30 towards above direction on be focused at together, and 3 link together along the plane, so just formed a longitudinal slot 31 between two antelabium 32, Open Side Down for this longitudinal slot, and shape of cross section is the V-shape with respect to plane 3 symmetries.

At cooresponding free end 21 places, the surface 22 of two outside listriums 19 self is connected to downwards on the longitudinal plane 33, and longitudinal plane 33 is tilted to down with respect to plane 3, and surface 33 is downward more the closer to the plane 3.

Surface 33 self is connected to downwards on the longitudinal plane 34, this longitudinal plane 34 is bevelleds with respect to plane 3, and it is downward more more near plane 3, such situation is just opposite with the surface 28 that is positioned at 3 the same sides, plane, make surface 34 be connected on the longitudinal plane 35 thus downwards by a diagonal plane, longitudinal plane 35 has constant slope ground and extends away from plane 3, and its position relation with plane 3 is opposite with the surface 29 that is positioned at 3 the same sides, plane.Surface 35 is connected to downwards on the longitudinal plane 36, this longitudinal plane is on the direction of leaving plane 3, with respect to plane 3 segment distance that stretched out obliquely, this distance is greater than the separation distance between listrium 19 upper surfaces 23 of plane 3 and the longitudinal plane 36 places outside, its bevelled towards be with the surface 30 that is positioned at 3 the same sides, plane towards opposite.

Like this, surface 34,35 has just formed an antelabium or clasp 37 at free end 21 places of this listrium 19, in the state that Fig. 2 and lead shown in Figure 37 and mounting and dismounting body 4 fit together mutually, this antelabium 37 corresponding antelabium 32 with on perpendicular to the direction on plane 3 is directly opposed, they have the shape and size of standard, so that be assembled in the groove 11 on the lead 7, this antelabium 32 in another groove clamping on the lead 7.On this position, two antelabium 32,37 are symmetrical with respect to the plane 8 of lead 7, and lead 7 remained between them, these two antelabium be positioned at fully lead 7 plane 9 the top or almost completely be positioned at the top on this plane 9, thereby cooresponding outside listrium 19 is being subjected to elastic deflection owing to its antelabium 37 will supported lead 7 to press to plane 3 on the direction of leaving plane 3 prestress effect, lead 7 self are being supported the antelabium 32 that is positioned at 3 the same sides, plane with described antelabium 37 again and are being pressed to plane 3.When making mounting and dismounting body 4, and lead 7 is being set in mounting and dismounting body the time, can by with each outside listrium 19 in the degree that suitable value is adjusted to this elastic deflection setting that is dimensioned at antelabium 32 and 37 places, on direction perpendicular to plane 8, two antelabium 32, relative spacing between 37 is less than a setting value, this setting value is corresponding to the relative spacing between two grooves 11 on the lead 7, thereby cause two corresponding antelabium 32,37 pairs of leads 7 have the desired effects of a clamp, so just lead 7 has been fixed in the mounting and dismounting body 4, perhaps more specifically, be to be fixed on vertically along in a plurality of mounting and dismounting bodies 4 of putting, and with each mounting and dismounting body 4 closed contacts, thereby on the entire longitudinal length direction, guaranteed the conductive relation of each mounting and dismounting body 4 and two leads 7.As is known, can be by between antelabium 32,37 and cooresponding groove 11, using a kind of contact lubricated dose of electric conductivity that advantageously improves herein.

Should be noted that: the clamp effect of mounting and dismounting

body

4 or 4 pairs of trolley wires 7 of a plurality of mounting and dismounting body, and the contact of conduction each other all must make outside listrium 19 be subjected to the prestress effect of elastic deflection.

Very naturally, owing to be symmetrical, so under the condition that two leads 7 are installed, because in the mutual balance of application force that applies to listrium 18 free ends 21 on 3 directions of plane, the deflection prestress of outside listrium 19 can't cause the deflection deflection of central listrium 18 generations to two outside listriums, 19 free ends 20 by corresponding lead 7.Under the situation that temporarily lacks a trolley wire 7, elastic deflection can take place in listrium 18 under the side direction push effect of the lead 7 that corresponding outside listrium 19 is installed, but this lead 7 still is enough to remain on two free ends 20 of central listrium 18 and corresponding outside listrium 19, between 37, on the one hand, the risk of so just having avoided the lead accident to deviate from, and can be convenient to two leads 7 in turn be installed to each mounting and dismounting body 4 below, and on the other hand, so also can keep contacting with the tight conduction of each mounting and dismounting body 4, thereby just can power, for example occur damaging and wanting under the split situation about laying down at another lead 7 with the supply line 1 that has solid conductor 7.

On direction away from plane 3, each surface 36 is connected with a longitudinal plane 38, longitudinal plane 38 is similar to parallel with plane 3, and than the surface 23 on the corresponding lateral border plate 19 further from the plane 3, and should be connected on this surface 23 by a longitudinal plane 39 on surface 38, longitudinal plane is substantially perpendicular to plane 3, thereby this plane is bending upwards, and protruding from outside listrium on away from the direction on plane 3.Position at surperficial 36 closest surfaces 38, three surfaces 36,38 and 39 have surrounded a sill platform 40 that is positioned at the rigidity on listrium 19 free ends 21 of the corresponding outside, its surface 23 from outside listrium 19 on away from the direction on plane 3 outwards stretches out, this sill platform especially is convenient between two adjacent vertical insulators that are folded down from the tunnel roof, a detouchable insulating boot (not shown) is fixed on the mounting and dismounting body, insulating boot is hiding the upper surface 14 of pedestal 13, edge face 16, and be fixed on the sill platform 40, thereby just covered the surface 23 of outside listrium 19, but the bottom of this insulating boot and laterally then be reveal empty, thereby exposing half of each bar lead 7 of being positioned at 9 belows, plane.Position on each 36 the most close corresponding surfaces 38, surface, preferably leave a hollow space a---longitudinal groove that Open Side Down 41 in the cooresponding sill platform 40, its cross-sectional plane is a V-shape, and with respect to a corresponding plane 42 symmetries, this plane 42 is arranged essentially parallel to plane 3, and like this, the groove 41 in sill platform 40 is positioned at from corresponding antelabium 37 and outwards departs from the position on plane 3, this groove 41 can utilize the elasticity of insulating boot, and advantageously reinforced insulation covers on the anchoring on the sill platform 40.

Naturally, the fish plate that is used for two adjacent mounting and dismounting bodies 4 are linked together in the vertical end-to-end must be to fastening the cause adverse effect of lead 7 on mounting and dismounting body 4, wherein, the elastic reaction of the fastening just utilization outside listrium 19 of lead in mounting and dismounting body 4 is realized, for this purpose, utilize each fish plate 5 of crossing over gap 6 together with outside listrium 19 clamping connections that are positioned at plane 3 homonymies on outside listrium 19 on the mounting and dismounting body 4 and the adjacent mounting and dismounting body 4, this fish plate is fixed on two outside listriums 19, thereby also is positioned at the same side on plane 3.

For this purpose, according to a kind of preferred embodiment, and as appreciable from Fig. 1 and Fig. 3, in the vertical near the position of mounting and dismounting body 4 each end face 12, some holes 44 have been got out on two outside listriums 19 of mounting and dismounting body 4, in the situation of present embodiment, be to hole along four axis that are parallel to each other 43, axis 43 is substantially perpendicular to perpendicular to plane 3, and on same longitudinal surface and athwartship plane, arrange respectively in pairs, hole 44 from a side of listrium through opposite side, so that cooresponding bolt 45 can pass hole 44 coaxially, these content representation but for the sake of clarity are not shown among Fig. 1 in Fig. 3.

The form of each fish plate 5 is a longitudinal type bar, it is between the outside of corresponding mounting and dismounting body 4 listrium 19 and central listrium 18, amplexiform on the surface 22 of two outside listriums 19 that will link together, and be threaded by a cooresponding bolt 45 and pressing these surfaces 22, has tapping hole 46 on the fish plate, these holes are relative with hole 44 respectively, and a spring washer 47 preferably also is set, and by this packing ring the head of bolt 45 are pressed on the surface 23 of corresponding outside listrium 19.

Embodiment by indefiniteness, the longitudinal size of each fish plate 5 is about 40 centimetres, the hole 43 of the most close end face 12 is about 5 centimetres apart from the longitudinal size of this end face 12 on the mounting and dismounting body 4, and is about 15 centimetres from end face 12 hole farthest apart from the longitudinal size of end face 12.But these accompanying drawings are the example of indefiniteness, select other numerical value also not depart from the protection domain of this aspect.

In addition, in order to prevent that fish plate 5 from contacting with central listrium 18, so fish plate 5 is being less than perpendicular to the thickness on 3 directions of plane in the distance between 26 perpendicular to plane 3 direction upper surfaces 22 and surface, and the length of bolt shank 45 will be designed to can avoid contacting on the central listrium 18.

But, the cross-sectional area of fish plate 5 will equal half of each mounting and dismounting body 4 cross-sectional areas at least, thereby, consider on the whole, the cross-sectional area that two fish plates 5 that two adjacent mounting and dismounting bodies 4 are assembled are in the vertical had is just identical with the area that a mounting and dismounting body 4 is had, thereby does not influence the transmission of electric current.

Thereby, assembling formed assembly with 5 pairs of mounting and dismounting bodies of fish plate is not only keeping these two leads 7 (except gap 6 on the total length of circuit, but on the one hand at this, the length in gap can be ignored), and guaranteed that the transmission of electric current all has enough sectional areas on whole vertical total length of circuit 1.

Thereby, embodiment as indefiniteness, the cross-sectional area that is made as 1600 square millimeters, each mounting and dismounting body 4 by the cross-sectional area with each fish plate 5 is set at 3120 square millimeters and the sectional area of lead 7 roughly is made as 107,120 or 150 square millimeters in test, just can obtain the good technical effect, can certainly select other numerical value, these numerical value are to not influence of the present invention.

The position of junction has got out a hole 63 perpendicular to plane 3 on side plate 51 between next-door neighbour surface 61 and corresponding front edge 59, and this hole is used for an affixed hook, thereby makes coaster to be drawn by work train road 1 along the line.

Axis 56 with respect to a pair roller 57 of plane 3 symmetries is positioned on the same Transverse plane 64, two transverse planes 64 of these formation are with respect to plane 50 symmetries, each plane 64 is all passed between cooresponding terminal dagger 52 and nearest that central dagger 53, and say that roughly it is identical apart from dagger 52 with 53 fore-and-aft distance.

Article two, axis 66 intersects with plane 64 perpendicular to plane 3 and by identical longitudinal plane 65 and forms, and described plane 65 is perpendicular to plane 3, and is positioned at the value between two parties of side plate 51 upper limbs 153 and the surface 61 meta height of lower edge 60.Along described diaxon 66, got out cooresponding hole 67 from a side to opposite side on the biside plate 51, hole 67 is surrounded by a columnar inner peripheral surface, and hole 67 is rotational symmetry with respect to axis 66, and the inner peripheral surface 68 in each hole 67 has identical diameter.

By on same axis 66, leaving pair of holes 67, side plate 51 is just supporting a roller set 69, they can freely rotate around cooresponding axis 66, this group roller comprises three rollers, comprising a middle roller 70 that is arranged on the plane 3, this roller is symmetrical with respect to plane 3, and comprises two outer side wheels 71, they are parallel to plane 3, and with respect to this plane symmetry.

Two group of 69 roller the 70, the 71st, identical, therefore, to only wherein one group be discussed with reference to Fig. 7, as can be seen from Figure 7, three rollers of same group 69 are supported between the biside plate 51 by same bolster 72, the axis of bolster is axis 66, and bolster extends to another side plate from side plate 51, and passes from cooresponding hole 67.

Between biside plate 51, bolster 72 has one section centre portion 73, this centre portion is being surrounded by an outer surface 74 in the radial direction away from axis 66, outer surface is the face of cylinder of standard, it is around axis 66 rotational symmetry, and its diameter for example is substantially equal to the diameter of hole 67 inner peripheral surfaces 68.Along axis 66 directions, the undersized of centre portion 73 between the biside plate 51 on perpendicular to plane 3 directions relative spacing, on direction away from plane 3, two outsides of outer peripheral face 74 are connected respectively on the plane shaft shoulder 75 of an annular, the shaft shoulder 75 is a rotational symmetry with respect to axis 66, and axis normal therewith; Two shaft shoulders 75 are with respect to plane 3 symmetries, and are on the position away from plane 3, but with respect to the side plate 51 that is in the same side, the shaft shoulder is slightly near plane 3.

Direction along axis 66, the both sides of centre portion 73 respectively have a bolster 72, has an end portion 76 at bolster 72, in the radial direction away from axis 66, this end portion is surrounded by a cylindrical shape outer peripheral face 77, this outer peripheral face is the rotational symmetry center with axis 66, and diameter is less than the diameter of outer peripheral face 74, be connected with the cooresponding shaft shoulder 75 between outer peripheral face 77 and the outer peripheral face 74, and this end portion 76 is passed cooresponding side plate 51 from the inner peripheral surface 68 of corresponding aperture 67, thereby outwards partly stretches out from this side plate 51 on away from the direction on plane 3.For this reason, along axis 66 directions, the outer peripheral face 77 of each end portion 76 is being connected on the direction away from plane 3 on the terminal surface 78, this end face 78 be shaped as card perpendicular to axis 66, and the both ends of the surface 78 with respect to plane 3 symmetries are separated a segment distance along the direction of axis 66, greater than the overall dimensions of the assembly that is made of biside plate 51, biside plate 51 wherein fits together by dagger 52,53 this distance mutually on perpendicular to the direction on plane 3.

Axle sleeve 79 by a coaxial setting has guaranteed that two end portion 76 of bolster 72 are coaxial with respect to cooresponding hole 67, axle sleeve wherein also guaranteed bolster 72 in side plate 51 with respect to plane 3 symmetries.

Two axle sleeves 79 relevant with same bolster 72 are identical, and with respect to plane 3 symmetries.

On axis 66 directions, two columnar inner peripheral surfaces 80,81 have all been formed in each axle sleeve, these two inner peripheral surfaces are the rotational symmetry center with axis 66, and the diameter of these two side faces equals the diameter of the outer peripheral face 74 of centre portion 73 on the diameter of outer peripheral face of bolster 72 end portion 76 and the bolster 72 respectively.The inner peripheral surface 80,81 of each axle sleeve 79 respectively with a part of outer peripheral face 74 moving contacts of a part of outer peripheral face 77 and the centre portion 73 of bolster 72 end portion 76, thereby can make bolster 72 rotate around axis 66.Two inner peripheral surfaces 80,81 of each axle sleeve 79 link together by the plane shaft shoulder 62 of an annular, this shaft shoulder is the rotational symmetry center with axis 66, and it is vertical with this axis 66, the shaft shoulder 62 relies on plane 3, and be flattened on the shaft shoulder 75 of bolster 72, but this mounting method allows axle sleeve 79 to rotate with respect to bolster 72 around axis 66.

On the direction away from the shaft shoulder 82, the inner peripheral surface 80 of each axle sleeve 79 is connected on the annular end face 83 along axis 66 directions, and this annular end face 83 is the rotational symmetry center with axis 66, and vertical with axis 66, and end face 83 is partial to leave the direction on plane 3.Along axis direction, end face 83 in the relative distance between the shaft shoulder 82 less than the distance of end face 78 between the shaft shoulder 75 in respective ends part 76 on the axis direction, the shaft shoulder 75 is wherein connecting end portion 76 in centre portion 73, like this, end portion 76 is just away from the direction on plane 3, outwards outstanding along axis 66 with respect to the end face 83 of corresponding axle sleeve 79.

For inner peripheral surface 81, it is along half less than certain size of the size of axis 66 directions, this size is meant the distance between two shaft shoulders 75 of axis direction upper support axle 72, thereby this inner peripheral surface 81 just can not extend to 3 places, plane, be connected on another end face 84 of axle sleeve 79 to inner peripheral surface 81 on the direction on plane 3, this end face is the plane of an annular, and around axis 66 rotational symmetry, simultaneously also perpendicular to this axis 66, thereby near plane 3.The end face of two axle sleeves 79 is close mutually, and with respect to plane 3 left-right symmetric, thereby on axis 66 directions, between them, leave a space 85, plane 3 is in this space, and this space is the plane of symmetry with plane 3.

Away from axis 66 in the radial direction, on its outer peripheral face 86,87 that the end face 83,84 of axle sleeve 79 is connected respectively to, outer peripheral face is towards the direction away from axis 66.

Each outer peripheral face 86,87 all has two parts, these two parts in the mode that hereinafter will describe in detail along axis 66 layout that is parallel to each other, on direction perpendicular to axis 66, the diameter of part 87 is greater than the diameter of part 86, and these two parts link together by the plane shaft shoulder 89 of an annular, and the shaft shoulder 89 is the rotational symmetry center with axis 66, and vertical therewith, this shaft shoulder 89 is in the position away from plane 3, and with respect to the shaft shoulder 82 of axle sleeve 79 certain side-play amount is arranged on this direction.On the direction of axis 66, this side-play amount equals in the axial direction between 72 liang of shaft shoulders 75 of bolster half of the difference of distance between length and the biside plate 51, thereby cooresponding side plate 51 at two shaft shoulders pushing tow on, make cooresponding axle sleeve 79 to rotate around axis 66 with respect to this side plate 51 and bolster 72 away from the direction on plane 3.This just can guarantee bolster 72 and cooresponding axle sleeve 79 are regulated with respect to biside plate 51, thereby makes that bolster 72 can be with respect to plane 3 symmetries, and two axle sleeves 79 relevant with bolster also can be relatively and same plane 3 symmetries.

With two firsts 90,91 of the shaft shoulder 89 direct neighbors, each outer peripheral face 86,87 is a drum, and be axis of symmetry with axis 66, the diameter at 91 part places of outer peripheral face 87 is greater than the diameter at part 90 places of outer peripheral face 86, the diameter at part 90 places equals the inner peripheral surface diameter in hole 67 on the side plate 51, thereby two parts 90 contact with the inner peripheral surface 68 of corresponding aperture 67, guiding the rotation of axle sleeve around axis 66 thus, it is coaxial with respect to the corresponding aperture 67 with same axis 66 also to have guaranteed axle sleeve 79 and bolster 72 simultaneously.

On axis 66 directions, the size of the part 90 of outer peripheral face 86 equals the thickness of side plate 51 at least, but less than in the terminal surface 83 of axis direction Upper shaft sleeve 79 and the length between the shaft shoulder 89, the thickness of its latus inframedium is to record on the direction of axis 66, so just make axle sleeve on away from the direction on plane 3 from side plate 51 protruding second portions 92, it also belongs to outer peripheral face 86, on the direction vertical with axis 66, this part 92 is a square, thereby can engage with a detachable spanner 88, in Fig. 5, can see this spanner, so just make that two axle sleeves 79 can be as required, rotate independently of each other around axis 66 with respect to side plate 51 and bolster 72, and can not be created in displacement on axis 66 directions.

Outer peripheral face 87 for axle sleeve 79, it has a second portion 93, this second portion connects the first 91 of outer peripheral face 87 to end face 84, be shaped on screw thread on the second portion, its diameter is greater than the diameter of first 91, like this with regard to make above-mentioned axle sleeve 79 around the rotation of axis 66 change into a corresponding sliding sleeve 94 along axis direction with respect to axle sleeve 79, the translation of bolster 72 and side plate 51, a sliding sleeve all has been installed on each axle sleeve 79, and it is installed into and can slides at axle sleeve upper edge axis 66, but can not rotate with respect to side plate 51 around axis 66, side plate 51 wherein is cooresponding with this axle sleeve 79.

For this purpose, the shape of each sliding sleeve 94 is essentially the annular cover, it is an axis of symmetry with axis 66, in the radial direction towards axis 66, this sliding sleeve 94 is surrounded by an inner peripheral surface 95, this inner peripheral surface comprises two parts 96,97, these two parts are to be arranged in order on the direction away from plane 3, attack on the part 96 and be shaped on one section screw thread, be shaped on supporting thread segment on the part 93 of axle sleeve 79 outer peripheral faces 87, the cooperation of sliding sleeve 94 and axle sleeve outer peripheral face is just as being connected of bolts and nuts, and on the direction perpendicular to plane 3, the length of part 96 is identical with the length of part 93; As for part 97, it also is cylindric, and be diad with axis 66, its diameter equals the diameter on axle sleeve 79 outer peripheral faces 87 tops 91, but on the direction perpendicular to plane 3, its length is less than length one segment distance of part 91, and this distance equals the distance that the free end 20 with the free end 21 of mounting and dismounting body 4 outside listriums 19 and central listrium 18 separates at least, so that lead 7 is split out, or this lead 7 is installed in this between the antelabium 32,37 between cooresponding antelabium 32,37.

On the direction on plane 3, tapping part 96 is connected on the end face 98 on sliding sleeve 94 inner peripheral surfaces 95, and this end face is a planar annular, and near plane 3, and is the rotational symmetry center line with axis 66, simultaneously also perpendicular to axis 66.On the home position of the sliding sleeve shown in Fig. 4,5,7,9 94, sliding sleeve 94 is nearest apart from plane 3, and under this state, tapping part 96 is tightened on the threaded portion 93, leaving axis 66 in the radial direction, the end face 84 of end face 98 and axle sleeve 79 becomes the relation of coplane.

On the direction away from plane 3, sliding sleeve also is subjected to the qualification of a planar annular 99, and this planar annular is the rotational symmetry center with axis 66, and perpendicular to this axis.Plane 99 is back to the plane 3, that is to say, this plane is positioned on the position that the side plate 51 with plane 3 homonymies faces, and under above-mentioned original position state, keep leaving a gap 100 with this side plate 51, the length of this gap on axis 66 directions equals the distance that above-mentioned free end 20 that mention, that make free end 21 and the central listrium 18 of outside listrium 19 separates, and so just can unclamp trolley wire 7 or attaches it in the mounting and dismounting body.

The length value of this gap 100 on axis 66 directions is less than the size of part 93,96, if suitably rotary sleeve 79 makes part 93,96 unscrew mutually, this gap width is the maximum possible displacement of sliding sleeve 94 with respect to axle sleeve 79, that is to say, make the range of sliding sleeve 94 with respect to bolster 72 and side plate 51.In the trip process, the part 97 on sliding sleeve 94 inner peripheral surfaces 95 is slided on the part 91 of axle sleeve 79 outer peripheral faces 87, thereby is stably keeping the coaxial relation of sliding sleeve 94 with respect to hole 67 on axle sleeve 79, bolster 72 and the side plate 51.

Like this, by engaging with the part 92 of square-section with spanner 88, make axle sleeve 79 rotate, just cause sliding sleeve 94 translation on perpendicular to the direction on plane 3, by a pin rod 101 is inserted in the hole 103, sliding sleeve 94 can not be rotated around axis 66 with respect to the side plate 51 that is positioned at 3 the same sides, plane, pin rod 101 is installed on the side plate 51 integratedly, it extends along axis 102, axis 102 is perpendicular to plane 3, but off-axis 66, pin rod equals the distance of side plate 51 apart from axle sleeve 79 end faces 84 at least from the distance that side plate extends to plane 3, and as much as possible near this distance value, hole 103 along axis 102 from the opposite side of a side through sliding sleeve 94, that is to say, from an end face 98 through other end 99.For example, the outer peripheral face 104 of pin rod 101 is cylindrical, this outer peripheral face is the rotational symmetry center with axis 102, pin rod is between corresponding side plate 51 and end plane 105, end face 105 is perpendicular to axis 102, and near plane 3, hole 103 is being defined as by a cylinder inner peripheral surface 106 in the radial direction towards axis 102, this inner peripheral surface is the rotational symmetry center with axis 102, and its diameter equals the diameter of outer peripheral face 104.Preferably as shown in Figure 6, several identical holes 103 are set on sliding sleeve 94, the axis 102 in these holes 103 equates apart from the distance of axis 66, and distribute around angular separation such as axis 66, thereby when coaster 48 is installed, can select certain Kong Laiyu pin rod 101 to engage from these holes 103, are a kind of like this states to guarantee home position 94: the outer face 98 of sliding sleeve is actually with outer face 84 coplanes of axle sleeve 79.

On direction away from axis 66, sliding sleeve 94 is limited by an outer peripheral face 107, this outer peripheral face is the rotational symmetry center with axis 66, and its shape can be selected within a large range, as long as this shape allows sliding sleeve 94 is adjusted, and the race, inner (specifically not marking among the figure) that can stop a thrust bearing 108 parallel to the axis 66 and perpendicular to the direction of axis 66 on any relatively moving taken place gets final product, the outer race of bearing 108 is not at length represented in the accompanying drawings yet, it is supporting the roller 71 of a corresponding side, it can freely be rotated with respect to sliding sleeve 94 around axis 66, and can not produce relative displacement.For this purpose, outer side wheel 71 is to be installed on the outer peripheral face 107 of sliding sleeve 94 by bearing 108, the installation direction of the shape of outer peripheral face 107 and thrust bearing 108 is common practise of those of ordinary skills, be understood that thrust bearing 108 the installation on the sliding sleeve 94 should make application force can be on away from the direction on plane 3 outside sliding sleeve 94 is delivered on the side wheel 71.

On the direction of axis 66, the size that is installed in roller 71 on the sliding sleeve 94 and bearing 108 is less than the size of sliding sleeve 94, and roller 71 should make along the set-up mode of axis 66 directions with respect to sliding sleeve 94: when sliding sleeve 94 is in its original position state, roller 71 is at the groove 41 that upwards joins in week on outside listrium 19 free ends 21 that are arranged in 3 the same sides, plane on the mounting and dismounting body 4, the shape of this outside listrium is designed to can be at antelabium 32, keeping a lead 7 between 37, these contents can be referring to Fig. 4, can see among the figure that two outer side wheels 71 all are in the original position state, and in Fig. 9, the roller 71 in left side just is in home position.

For this purpose, in the radial direction away from axis 66, each outer side wheel 71 all has an annular ring side face 109, this ring side face is around axis 66 rotational symmetry, and when when observing through the section of respective axes 66, on away from the direction of axis 66 is a convex surface, specifically, this ring side face is the V-type face with respect to plane 110 symmetries, and basically with the section shape complementation of groove 41, plane 110 wherein is vertical with axis 66, like this, under the above-mentioned original position state of sliding sleeve 94, this shape can be approximate matching with the groove 41 on outside listrium 19 free ends 21 that are positioned at plane 3 homonymies at least, and at this moment, this outside listrium 19 is on such position with respect to central listrium 18: at their antelabium 32, keeping a lead 7 between 37, thereby this moment, plane 110 and 42 was to overlap approx at least.

Nature, each outer side wheel 71 encircle side faces 109, and function is suitable therewith with respect to the diameter of axis 66.Those of ordinary skills are readily appreciated that its diameter should be designed to like this: on the direction perpendicular to the two axial lines 66 that is in same plane 64 and 56, interval between the ring side face (marking among the figure) of outer side wheel 71 ring side faces 109 and roller 57 is substantially equal in the size of space on the transverse direction that is parallel to plane 3, between groove 41 bottom surfaces and this sill platform 40 longitudinal planes 39, and roller 57 wherein is laminated on the sill platform.

As for central roller 70, its groove 31 with central listrium 18 free ends 20 engages.

For this reason, in the radial direction away from axis 66, the shape of the ring side face 111 of central authorities' roller 70 is also around axis 66 rotational symmetry, and attenuation gradually on away from the direction of axis 66, thereby when on a process section of axis 66, observing, its shape is an evagination, and more specifically, this shape is the V-shape complementary basically with the section shape of groove 31.For those of ordinary skills, the diameter of central authorities' roller 70 ring side faces 111 should be confirmed as: this ring side face 111 engages with groove 31, and cooperate therewith and guarantee: when coaster 48 is suspended on the circuit 1 by its roller 57, the vertical central plane of symmetry of coaster 48 overlaps with the vertical central plane of symmetry 3 of circuit 1 (specifically being mounting and dismounting body 4), wherein, roller 57 is pressed on the surface 39 of two sill platforms 40.

When coaster 48 rolls on sill platform 40, for keeping coaster 48 and this position of circuit 1 or mounting and dismounting body 4 to concern, roller 70 is installed into like this: make it freely to rotate around axis 66 with respect to bolster 72, but cannot produce relatively independent displacement with two coaxial outer side wheels 71.For this purpose, in space 85, bolster 72 is supporting the race, inner 112 of a thrust bearing 113 regularly on the both direction of axis 66, because this set-up mode is known to those of ordinary skills, so will no longer describe in detail hereinafter.Bearing 113 is through plane 3, and be provided with symmetrically with respect to plane 3, in addition, it also has an outer race 114, and it is fixing central roller 70 by suitable mode, and fixed form wherein is known to those of ordinary skills, thereby do not describe, so central roller 70 has an annular inner peripheral surface 115 towards axis 66, it suitably is made for axis 66 is the rotational symmetry center.

Central authorities' roller 70 is except having the effect that coaster 48 is positioned with respect to the mounting and dismounting body 4 of circuit 1, preferably, can prevent that the corresponding sliding sleeve 94 with its two coaxial outer side wheels 71 from having surpassed their home position on the direction near plane 3 also as a backstop.

For this purpose, on the direction away from plane 3, the inner peripheral surface 115 of central roller 70 is connected on the annular end face 116, and this annular end face is around vertical therewith axis 66 rotational symmetry.Both ends of the surface 116 are with respect to plane 3 symmetries, and on perpendicular to the direction on plane 3, leave a distance mutually, this distance equals and the distance of central roller 70 between the both ends of the surface 84 of two axle sleeves 79 on the same axis 66, end face 116 faces with the end face 98 of corresponding sliding sleeve 94, thereby, if under the situation that reaches home position, force sliding sleeve 94 to move by tighten corresponding axle sleeve 79 with spanner 88 in direction near plane 3, end face 98 and end face 116 are connected, thereby carry out stop.

In the radial direction away from axis 66, the end face of central authorities' roller 70 is connected on the outer peripheral face 117, this outer peripheral face is a cylindrical shape, and be rotational symmetry with respect to axis 66, its diameter for example equals the diameter of a part on sliding sleeve 94 outer peripheral faces 107, this position and end face direct neighbor, the ring side face 111 of roller 70 is connected with this outer peripheral face 117 by two annular shaft shoulder faces 118, annular shaft shoulder face 118 is around perpendicular axis 66 rotational symmetry, two shaft shoulder faces are with respect to plane 3 symmetries, and leave plane 3, and on 66 the direction of paralleling to the axis, the interval between the two is less than the interval between the both ends of the surface 116.

As can be seen from the figure, because two axle sleeves 79 are separate around respective axes 66 with respect to the rotation of side plate 51, so on direction, can adjust separately the position of one of them outer side wheel 71, away from home position away from plane 3.Like this, outer side wheel 71 can be on the direction away from plane 3 on any suitable position, these positions comprise home position, can realize this function by any measure, especially pitch and the apparent order and condition by double thread part 93 and tapping part 96 is provided with, and is self-locking unless make the work of axle sleeve 79 in corresponding sliding sleeve 94 screw---specially rotate the part 92 that has the square-section on these axle sleeve 79 outer peripheral faces 86 with spanner 88.

In addition, along the plane 3 and plane 50 intersect the axiss of pitch 119 that form---that is to say that this axis 119 is positioned at the centre on two planes 64 and the centre of biside plate 51, have a nut 120 integratedly on the middle dagger 53, this nut 120 spins with a coaxial screw rod 123 mutually by one section screw thread 112, below dagger 53, screw rod has a square termination, and an available spanner that is similar to spanner 88 is screwed it.Be higher than dagger 53 but be lower than the height place of side plate 51 vertical upper limbs 153, screw rod 123 has a upper end, it is fixed and can not translation on the direction of axis 119, but can freely rotate around this axis 119, one for the balladeur train of yoke shape has two parallel cheeks 121, and their positions are with respect to axis 119 symmetries.Each cheek 121 is all supporting the cam follower 125 of a rigidity integratedly, this cam follower 125 joins to always in the slotted hole 127 by a coaxial end lug 126, two cheeks wherein along same axis 124 from axis 119 to the both sides projection, axis 124 is vertical with axis 119, on plane 50, respectively be shaped on a slotted hole 127 on the biside plate 51 respectively, and the longitudinally of slotted hole parallels to the axis 119, like this, the joint of lug 126 in slotted hole 127 remains on two cheeks 121 on the position with respect to plane 3 symmetries.Like this, just prevented to rotate with respect to underframe 49 around axis 119 at york piece 120 on the axis 124---especially at screw rod 123 when axis 119 rotates with respect to underframe 49, thereby, the rotation on this direction only can cause york piece 120 and axis 124 thereof away from or near the direction of axis 124 on respect to 53 translations of the dagger on the underframe 49, and in contrast near or away from circuit 1.The pitch of screw thread 122 is self-lockings on screw rod 123 and the nut 120, thereby hereinafter under the normal operating conditions that will describe, york piece 120 can keep its position of specially setting with respect to the underframe 49 and the circuit 1 of coaster 48, and the setting of position is undertaken by screw rod 123 is rotated with respect to nut 120 around axis 119.

Be provided with a bearing 128 between two cheeks 121 of york piece 120, it is installed into and can rotates around axis 124, thereby just can freely rotate with respect to york piece 120 around axis 124, but the displacement of other form can not be arranged.This bearing 128 is placed in the middle layouts with respect to the axis 66 of

roller

70 and 71, it has an outer peripheral face 129 in the radial direction away from axis 124, this outer peripheral face is with respect to axis 124 rotational symmetry, this outer peripheral face 129 is perpendicular to plane 3, and be distributed in the both sides on plane 3 equably, its between the size on this direction is greater than vertical central plane 8 of 1 liang of lead 7 of circuit perpendicular to the interval on 3 directions of plane, but less than two grooves 41 on perpendicular to plane 3 directions at interval.

On axis 126 directions, outer peripheral face 129 has two ends 130, they are with respect to plane 3 symmetries, and has a middle body 131, it is through plane 3, and with respect to this plane symmetry, and these three parts 130,131 all are cylindrical, and be the rotational symmetry center line, and has identical diameter with axis 124.Both ends 130 are connected on the middle body 131 by cooresponding two centre portions, centre portion be shaped as a circular groove 132, this circular groove is around axis 124 rotational symmetry, and with respect to a plane symmetry, this plane parallel is in the plane 3, and overlap, thereby also refer to Reference numeral 8 with cooresponding plane 8.Similar with two planes 8, centre portion 132 is also with respect to plane 3 symmetries.

More specifically, each groove 132 has the side 133 of two, frustoconical 124 axisymmetric around axis, and columniform bottom surface 134, the bottom surface is the rotational symmetry center line with axis 124 also, but its diameter is less than the diameter of part 130 and 131, two sides 133 are respectively with respect to two planes, 8 symmetries, and plane 8 134 is passed from the bottom surface symmetrically.

Those of ordinary skills can easily determine the position and the size of two sides 133 and bottom surface 134 in each groove 132, make and work as Fig. 4,5, when like that coaster 48 being fixed on the mounting and dismounting body 4 of circuit 1 shown in 8 and 9, by regulating the height of york piece 120 with respect to dagger 53 on the underframe 49, bearing 128 can be taken to such position: on this position, the point that is positioned on groove 132 two sides 133 and the bottom surface 134 on the Up Highway UHW by cooresponding lead 7 roof pressures, but can not hinder vertical rolling of coaster 48 roads 1 along the line or mounting and dismounting body 4, and mounting and dismounting body is contacted with the side 121 of york piece 120, Up Highway UHW wherein is positioned at plane 3, and lead is then by two antelabium 32 of mounting and dismounting

body

4,37 are keeping.

But, by adjusting bearing 128 along the position of axis 119 apart from dagger 53 on the underframe 49, can also make bearing 128 enough near near these daggers 53, size by suitably designing bearing, york piece 120 and screw rod 122 just can so that on the bearing 128 Up Highway UHW of the side 133 of each groove and bottom surface 134 to leave corresponding lead 7 downwards enough far away, this distance should equal the radius of lead 7 at least, these contents are not shown among the figure, but those skilled in the art can understand these contents at an easy rate.

Naturally, above-mentioned description right and wrong to bearing 128 mounting meanss are determinate for example, also can select other device for use---especially to the mode of york piece channeling conduct, york piece is as a balladeur train, supporting bearing 128, to its guiding be the slideway of 119 orientations that parallel to the axis, it is installed on the underframe 49 integratedly, in the example shown, this slideway is made of long slot bore 127.

With this understanding, as described in hereinafter wanting, just can carry out the renewal repair of circuit 1 with coaster 48, this is to be that the trolley wire of changing wherein 7 is realized by dismantling down whole circuit in advance, more specifically, mounting and dismounting body 4 need not be disassembled from the insulator that supports it exactly.

At first the time, circuit 1 is in Fig. 1 to state shown in Figure 3, that is to say, one or more mounting and dismounting bodies 4 utilize the elastic deflection precompressed effect of outside listrium 19 and trolley wire 7 are remained between the

antelabium

32,37, and elasticity precompressed effect wherein is the free end of pressing to central listrium 18 from the free end of outside listrium.Circuit 1 and the mounting and dismounting body structure 4 represented among Fig. 4 and Fig. 5 also are under such state.

The operation of first step is included in after lead 7 cut-outs, immediately coaster 48 is installed on the circuit 1, thereby make two outer side wheels 71 that are in home position and central roller 71 in each roller set 69 join to respectively in cooresponding groove 41 and the groove 31, and being advanced with the longitudinal direction of setting in the vertical in coaster 48 roads 1 along the line, roller 57 is pressed on the surface 38 of sill platform 41 of outside listrium 19 free ends 21.

For this purpose, interval between two axle sleeves 79 and the cooresponding two outer side wheels 71 should be as much as possible little at initial time, and bearing 128 lowland as far as possible descends near the dagger 53 on the underframe 49, these contents are not expressed in the drawings, but those skilled in the art can easily understand these contents.

Then, central authorities' roller 70 has guaranteed that the vertical central plane of symmetry of underframe 49 overlaps with the plane of symmetry of circuit 1, these two planes refer to same number designation 3, and the middle plane of each groove 132 overlaps with plane 8, and the mid-plane of roller set 69 China and foreign countries' side wheels overlaps with the middle plane 42 of respective grooves 41.

Set after the initial position, bearing 128 is left lead 7 one segment distances downwards, and this distance will equal the radius of lead 7 at least, and preferably greater than this radius.

Like this, do synchronously or the suitable rotation that replaces with respect to underframe 49 around axis 66 by make two axle sleeves 79 with spanner 88, will make two outer side wheels 71 in same group 61 leave central roller 70 gradually, if roller 70,71 outer peripheral portion joins to respectively in groove 31 and 41, then the free end 21 of outside listrium 19 will leave the free end 20 of central listrium 18 gradually by elastic deflection takes place with respect to plane 3, and owing to be the cause of symmetry, deflection does not then take place in central authorities' listrium, such state lasts till always makes outside listrium 19 reach the maximum flexibility degree of crook of its setting, in the case, as shown in Figure 8, two leads 7 just are in free movement state between antelabium 32 and 37.Then, stop the rotation of axle sleeve 79, guiding line 7 applies a downward pulling force slightly, and just to be enough to keep it be the state of straight line substantially, applying application force is to be used for overcoming contact lubricated dose adhesive effect on the one hand, overcomes mounting and dismounting body 4 on the other hand still to the maintenance trend of these leads; Owing to subsequently bearing 128 is being transferred to this position, so just can lead be reduced to partly enough low by making lead 7 whips, so fully they have been torn open from mounting and dismounting body 4, on above-mentioned described direct of travel, be located immediately at least the lead of coaster 48 back split come out.

Then, by this coaster 48 of tractive on this direction, just can make its required entire longitudinal length of on circuit 1, walking step by step, thereby certain vertical setting regions of one or more mounting and dismounting body 4 outside listriums 19 is in turn opened the maximum flexibility degree of flexibility, can unclamp trolley wire 7 thus, so just can in turn unclamp this vertical regional area of circuit 1.

Naturally, on direct of travel, the mounting and dismounting body 4 at coaster 48 rears is tending towards returning to the original position state, but this trend is repressed, this realizes by fixing lead 7, thereby but makes lead be lower than just fixing cord 7 of mounting and dismounting body place height by continuing to apply enough downward pulling force to the lead 7 at direct of travel upper pulley 48 rears.

Like this, along with advancing of coaster 48, it has little by little unclamped lead 7 simultaneously, thereby the whole piece lead that will need to change has all unclamped, up to another cut-off part that arrives lead 7.

End of a period at the trip, each mounting and dismounting body 4 in this zone on road 1 along the line just has been totally released lead 7, coaster 48 just can reset to this regional original position on the direction opposite with direct of travel---and for example be by on one or more mounting and dismounting bodies 4, rolling, mounting and dismounting body 4 outside listriums 19 that coaster 48 will be positioned at this zone circuit 1 upstream side this moment have been expanded to the maximum flexibility deflection degree, and updrift side wherein is with respect to above-mentioned direct of travel definition.

If necessary, can also carry out brushing and re-lubrication afterwards to

antelabium

32,37.

Then, in the corresponding space between the groove 132 that just longitudinal end of a lead 7 can be inserted into bearing 128 and two

antelabium

32,37, and make that face overlaps with the middle face of groove 132 in vertical symmetry of lead 7, this is to make bearing 128 risings get back to the position shown in Fig. 5,6 by rotary screw 122 to realize, will make the position of groove 11 between two corresponding

antelabium

32,37 of distal portion place two leads 7 like this, up to making the plane 9 of distal portion two leads 7 be on the final height with respect to mounting and dismounting body 4.

After new lead 7 has carried out correct longitudinal register with respect to the next-door neighbour's lead 7 at the upstream side of coaster 48 above-mentioned direct of travels with two, just they can be coupled together, and making coaster 48 advance with respect to one or more mounting and dismounting bodies 4 on the above-mentioned direct of travel---this realizes by carry out tractive on this direction, also two outer side wheels 71 are remained on the control position simultaneously, on the free end 21 of lateral border plate 19, with pulling force outside listrium 19 is expanded on the maximum deflection degree, and keeps bearing 128 on such position: it makes its plane 9 be positioned at the position of final height with respect to mounting and dismounting body 4 lead 7 holders.

Along with coaster advancing along one or more mounting and dismounting bodies 4, vertical part of the mounting and dismounting body outside listrium 19 that 71 pairs of outer side wheels are arranged in order on direct of travel expands into the structure of maximum flexibility deflection, subsequently, elastic bending takes place by the new lead 7 that makes next-door neighbour's coaster 48 the place aheads and is arranged in the groove 11 at part place in the bearing 128 between mounting and dismounting body 4

antelabium

32,37, wherein, the part of new lead 7 also is arranged in order on this direction, and the place ahead of coaster is also at direct of travel; On this direction, process, the rear the successively mounting and dismounting body of coaster 48 4 positions are tending towards returning to its original position state, but because

antelabium

32,37 has been stuck in the groove 11 of lead 7, so can only keep it to be subjected to the intermediateness of deflection precompressed, this just makes lead 7 be maintained at Fig. 1 under state shown in Figure 3, thereby circuit 1 is repaired successively.

In case coaster 48 does not have the other end position of lead 7 when having arrived it near circuit 1 beginning, in the mode that does not have expression in scheming but one of ordinary skill in the art will appreciate that, thereby rotary sleeve 79 makes it get back to the original position state, that is to say, make two outer side wheels 71 of each roller set 69 close mutually, and keep bearing 128 motionless, this just makes two outside listriums at the mounting and dismounting body 4 of this end also return under the state of deflection precompressed, under this state, outside listrium remains on lead 7 between

antelabium

32 and 37.

Coaster 48 can be removed from mounting and dismounting body 4, that is to say from the circuit of repairing again in the above described manner 1 to remove.

From above as can be seen, this method that is used to renovate the lead 7 that circuit 1 is installed also can be used for such circuit is carried out original installation, and this can use after mounting and dismounting body 4 is suspended on the tunnel roof by each supporting member and connects with fish plate.

In a kind of variations, relate to the situation of only changing a trolley wire 7, also can use this coaster by above-mentioned mode, as above-mentioned the discussion, by rotation with the axle sleeve 79 of the restringing of wanting 7 homonymies, just

relative antelabium
