Description

  The present invention relates to a method for installing a branching device on a track rail and a sleeper used for installing a new branching device on a branching vehicle transporter that has been brought into the field at a branching device installation position from which an old branching device has been removed on a trackway. It relates to a hanging bracket.

  In order to install a new branching device in place of the old branching device, a new branching device is assembled at a location away from the branching device installation location (the old branching device has been removed) due to the difficulty of securing the work place. For example, a new branching device is transported to the installation site by a transport vehicle described in Patent Document 1 or 2, and is separately prepared by lowering it on the roadbed by a crane device provided in the transport vehicle or a separately prepared crane. The crane is installed at a branching unit installation position where the old branching unit is removed using a crane vehicle or a large-sized Yamakoshi device that is heavy (see, for example, Patent Documents 1 and 2).

  In the embodiment, before the operation (step) of loading the branching device A over the branching device transporter C, as shown in FIGS. 8 to 13, the first basic rail A1 constituting the branching device A, the first The balance rail 3 is assembled to the sleeper B on which the one ton gray rail A2 and the second basic rail A1 ′ are placed by using the required number of sleeper hanging fittings 1 described later.

  As described above, this assembling work may be performed in parallel with the loading work of the branching device A on the branching vehicle C. However, if it is performed before the loading work, it is necessary to perform on the roadbed where the scaffolding is unstable. Since there is no, safety can be secured.

  As the balance rail 3, a rail material for a track having an appropriate length is used as it is. This is because the catch 400 with a roller of the chain block 4 (FIGS. 4 and 5) can be used as it is and can be lifted. In FIGS. 4 and 4, reference numeral 300 denotes a head of the balance rail 3, 301 denotes a leg portion of the balance rail 3, and 400A denotes a roller of the catch 400 with a roller. Here, the head portion 300 of the balance rail 3 serves as a latching portion, and the leg portion 301 serves as an assembly portion. In addition, the chain block 4 and catch 400 with a roller used for a Yamakoshi device are well-known.

(Composition of sleeper hanging bracket)
Next, the sleeper fitting 1 for assembling the balance rail 3 to the branching device A will be described.

  As shown in FIGS. 8 to 13, the sleeper hanging bracket 1 is for hanging a sleeper B on which a branching device A is placed, and includes a beam portion 11, a pair of holding frames 12 and 12, and a pair of first The first clamp bolts 13 and 13 and the second clamp bolts 14 and 14, the balance rail receiving portion 15, the four balance rail pressing pieces 16 and the third clamp bolt 17 are provided.

  As shown in FIGS. 8 to 11, the beam portion 11 includes a bottom plate 112 and a second clamp bolt 14 on the side of the sandwiching frames 12, 12 between a pair of side plates 111, 111 longer than the lateral width of the cross section of sleeper B. , 14 is provided with a pair of abutting plates 113, 113 with which the front end portions abut. On both sides of the pair of side plates 111, 111, shaft portions 111a that rotatably support the pair of sandwiching frames 12, 12 are provided. On both sides of the bottom plate 112, there are provided first bolt holes 114, 114 into which first clamp bolts 13, 13 for pressing the sleeper B in the vertical direction are screwed.

  As shown in FIGS. 8 to 13, each of the pair of holding frames 12 and 12 is longer than the longitudinal width of the cross section of sleeper B, and has a lower end that extends inward and contacts the lower surface of sleeper B. A plurality of mounting holes 124 and 124 for fixing the side support portions 121 and 121 with bolts 125 are provided, and the shaft portions 111a on both sides of the beam portion 11 can be rotated at positions lower than the upper end portions. Installed. In addition, bolt support plates 123 and 123 are provided above the shaft portion 111a, respectively, and second clamp bolts 14 and 14 for pressing the sleeper B in the lateral direction on the bolt support plates 123 and 123, respectively. Are provided with second bolt holes 122 and 122 into which the screw bolts are engaged.

  In order to assemble the balance rail 3 to the turnout A using the sleeper suspension 1 configured as described above, first, the sleeper attachment 1 is attached to the sleeper B on which the turnout A is placed.

  Next, the branching device installation method in the track rail according to the present invention will be described.

(Branch A is loaded on the Branch Car C)
First, the branching device A is loaded onto a plurality (three in the embodiment) of the branching vehicle transporter C arranged at an appropriate interval on the existing track rail.

(Mounting of sleeper 1 to sleeper B)
Next, when this sleeper suspension fitting 1 is fixed to sleeper B, the first clamp bolts 13 and 13 and the second clamp bolts 14 and 14 are loosened in advance as shown in FIG. The pair of holding frames 12, 12 is prepared so that the lower end portion of the pair of holding frames 12, 12 is widened and can be easily inserted into the sleeper B.

  Then, as shown in FIG. 12 (b), a sleeper B is inserted between the pair of holding frames 12, 12 of the sleeper hanging fitting 1, and first, as shown in FIG. By rotating the front end portions of the second clamp bolts 14, 14 on the frame 12, 12 side against the left and right side surfaces 113, 113 of the beam portion 11, the lower ends of the pair of sandwiching frames 12, 12 are moved. The sleeper B is moved toward the sleeper B, and the sleeper B is sandwiched by the pair of sandwiching frames 12 and 12 from both the left and right sides.

  Next, the first clamp bolts 13 and 13 on the beam part 11 side of the sleeper hanging metal fitting 1 are rotated so that the swivel parts 131 and 131 at the tips thereof are pressed against the upper side surface of the sleeper B, as shown in FIG. As described above, the sleeper B is clamped from both the upper and lower sides by the first clamp bolts 13 and the lower side support portions 121 and 121 of the pair of clamping frames 12 and 12, respectively.

  As a result, according to the sleeper hanging bracket 1, the sleeper B can be clamped from both the left and right directions by the pair of clamping frames 12, 12 while being adjusted by the second clamp bolts 14, 14, and the first clamp bolts 13, 13 are used. Since the sleeper B is sandwiched from above and below by the first clamp bolts 13 and 13 and the lower support members 121 and 121 of the pair of sandwiching frames 12 and 12 while adjusting, the cross-sectional shape of the sleeper B and the longitudinal direction of the cross-section Even if the length is changed or a slight difference in dimension occurs in the cross section of the sleeper due to aging, the sleeper B can be fixed to the sleeper B corresponding to the change or slight difference in dimension.

  Further, in this sleeper hanging bracket 1, bolt support plates 123, 123 are provided above the shaft portions 111 a of the pair of holding frames 12, 12, and the second bolt holes 122 are formed in the bolt support plates 123, 123. , 122 are provided, as shown in FIG. 12 (a), when the lower ends of the pair of holding frames 12, 12 are expanded and attached to sleepers B, the bolt support plates 123, 123 are used. The lower end portions of the pair of holding frames 12 and 12 can be opened more widely, and the attachment workability when attaching the sleeper hanging bracket 1 to the sleeper B is improved. Therefore, according to this sleeper hanging fitting 1, it is not limited to the attachment of the sleeper B having a specific shape, and the cross-sectional shape is a trapezoidal shape, a square shape, or a vertically or horizontally long rectangular shape, etc. It becomes possible to use it for the attachment of multiple types of sleepers B.

  In addition, sharp tips 121a are formed at the tips of the lower side support portions 121, 121 of the pair of sandwiching frames 12, 12 so that the tips are sharply formed and protrude upward and pierce the lower side of sleeper B. Therefore, as shown in FIG. 13 (b), when the first clamp bolts 13, 13 are rotated and the swivel portions 131, 131 at the tips thereof are pressed against the upper side surface of the sleeper B, the sharp protrusions 121 a are formed in the sleeper B It can be attached to sleeper B in a stable state because it digs into the lower surface of the sword or even bites it without being stabbed. However, in the present invention, provision of the sharp protrusion 121a is optional and may be omitted.

  Further, at the lower ends of the pair of sandwiching frames 12 and 12, a plurality of steps (here, a plurality of upper and lower support portions 121 and 121 can be mounted in accordance with the longitudinal length of the sleeper B cross section). For convenience of explanation, for example, the number of mounting holes 124 and 124 is three, but the number is not limited to three. Therefore, even when there are a plurality of longitudinal (vertical direction) lengths of the cross section of the sleeper B to which the sleeper hanging bracket 1 is to be attached, the attachment height of the lower side support portions 121 and 121 in the pair of holding frames 12 and 12 By adjusting, the length in the vertical direction (vertical direction) can be attached corresponding to a plurality of sleepers B. For example, when the cross-sectional shape of sleeper B is square, the lower side support portions 121 and 121 are attached to the middle mounting holes 124 and 124, while in the case of vertical sleeper B having a longer vertical length than that, Lower side support portions 121 and 121 are attached to the lower mounting holes 124 and 124, and in the case of a horizontal sleeper B having a short vertical length, the lower side support portions 121 and 121 are attached to the uppermost mounting holes 124 and 124. Will be installed.

(Attaching the balance rail 3 to the sleeper hanging bracket 1)
After fixing a plurality of sleeper suspension brackets 1 to sleepers B at appropriate intervals as described above, the balance rail 3 is placed on the balance rail receiving portion 15 of each sleeper suspension bracket 1 as shown in FIGS. The third clamp bolts 17 are inserted into the bolt holes of the balance rail receiving part 15 and the bolt holes of the four balance rail pressing pieces 15 and tightened. Thereby, the leg part 301 of the balance rail 3 is clamped between the upper surface of the balance rail receiving portion 15 and the pressing surface (bottom surface) of each of the four balance rail pressing pieces 16, and the balance rail 3 is attached to the sleeper hanging bracket. 1 can be detachably fixed.

(Branch A is loaded and moved on a plurality of branch trucks C1)
As shown in FIG. 1 (a), the branching device A is hung over a plurality of branching device transporting vehicles C with appropriate intervals as shown in FIG. The branching vehicle C loaded with the branching device A is moved to the site where the old branching device has been removed from the loading place.

(Appropriate number of rails Yamakoshi T are installed at the new installation location of branching device A)
At the newly installed place of the turnout, which is the place where the old turnout is removed, an appropriate number of rail Yamakoshi T,... It is installed along (in the longitudinal direction of the rail) so that the installation (installation) of the branching device A can be immediately performed. It is not always necessary to install all the required number of rail Yamakoshi Ts. The branching unit A is being transferred from the branching vehicle C side to the rail Yamakoshi T side, which is appropriately installed (the rails already arranged). It is not inconvenient to sequentially add new rail Yamakoshi T to the already arranged rail Yamakoshi T group on the Yamakoshi T side.

Rail Yamakoshi unit T (known), as shown in FIGS. 6 and 7, the support legs T ₁ of the longitudinal ends, provided with a crane T2 having a running path to the top surface, the crane T2 is traveling path It is provided with two chain blocks 4 and 4 that move freely.

(Delivery of turnout A from turnout carrier C to rail Yamakoshi T)
When the earliest branching device transporter C reaches the branching device installation location from which the old branching device has been removed (FIG. 1 (a)), the first branching device transporter vehicle C in the traveling direction includes the longitudinal direction of the branching device A. One end of the rail is longer than the disengagement distance to the rail catch 400 of the rail Yamakoshi T, which is arranged closest to the dead center from the dead center position of the track rail where the branching vehicle C can move forward. It is protruding. Therefore, the protruding portion at one end in the longitudinal direction of the branching device A is located above the rail catch 400 with a roller of the chain block 4 arranged at the position along with the movement of the branching vehicle C (FIG. 1B). In this state, when the tip portion is lifted by operating the chain block 4, the tip portion is disposed at a substantially normal position. In this state, the earliest transport vehicle is stopped by a brake or the like.

  Then, when another branching device transporter C is moved in this state, the balance rail 3 positioned on the branching unit A loaded on the branching unit transporting vehicle C is brought into sliding contact with the roller 400A of the rail catch 400 with a roller. Guided according to the rolling of the roller 400A, the next stage Yamakoshi T is placed on the rail catch 400 of the next stage Yamakoshi T by the same operation as described above. At that time, the branching vehicle C that has moved to the forward dead center position stops.

  And the said front-end | tip part is sequentially sent to the rail Yamakoshi T, ... arranged side by side in the moving direction by the branching-equipment transporter C in the next stage (FIG. 1 (c)), and finally the branching-unit transporting vehicle C. The branching device A that is loaded and loaded is supported by the rail catches 400 of the appropriate number of Yamakoshi Ts arranged in a straight line, and is placed directly above the installation location where the old branching unit was located (FIG. 1 ( d)).

  During this state, the rail catch 400 of the Yamakoshi device A is loaded with a load such as the branch device A. Therefore, even if the balance rail 3 assembled to the branch device A swings, Since the position of the chain block 4 can be changed along the traveling girder T2, the transfer operation from the branching device transporter C to the rail Yamakoshi T is performed without any inconvenience.

  In the present embodiment, the balance rail 3 is also arranged on the second basic rail A1 of the branching device A according to the inclination of the first basic rail A1 and the first tongs arranged along a straight line. In order to balance the load on the rail A2 side, only the balance rail 3 arranged on only two rails is arranged in parallel (like the first basic rail A1 and the first tongue rail A2). If there is no inconvenience, the load balance at the time of movement can be taken. Therefore, the balance rail 3 of the second basic rail A1 ′ portion in the embodiment may be omitted.

  The balance rail of the second basic rail A1 ′ is short corresponding to the rail A1 ′ (inclined portion thereof), but the chain block that receives and supports the balance rail is inclined to move the branching device A. As described above, the balance rail according to the second basic rail A1 ′ can automatically move from the rail catch 400 of the Yamakoshi device T when it reaches the predetermined rail Yamakoshi device T position. Needless to say, it's out of the way.

  In addition, the length of the balance rail 3 used for the first basic rail A1 or the like is equal to or longer than the rail (in the case of the second basic rail A1 ′, an inclined portion, that is, a portion protruding outward from the first tongue rail A2). Is more effective.

(Drop branch device A to the branch device installation location)
Then, the branching device A supported by a large number of Yamakoshi devices T,... Installed side by side at the branching device installation location is lowered to the branching device installation location by operating the chain block 4 of the Yamakoshi device T (FIGS. 2, 3). ). And the installation operation of the branching device A is complete | finished by loosening the volt | bolt 6 and removing the balance rail 3 and the sleeper hanging bracket 1.
