Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
One kind being used for straddle-type monorail PC track girder LFM signal limiting device, and track girder 2 is placed on pier shaft bent cap 1,
It is characterized in that, the limiting device includes multiple position-limit mechanisms, the track girder 2 passes through position-limit mechanism and 1 phase of pier shaft bent cap
Connection；The position-limit mechanism includes screw rod 3, and described 3 one end of screw rod is connected with track girder 2, and the other end is connected with pier shaft bent cap 1
It connects；The invention discloses a kind of limiting devices for 2 Serial regulation of track girder, because track girder 2 belongs to high-altitude work when being laid with
Industry, if fettering the motion amplitude of track girder 2 without limiting device, is easy to happen security risk in Serial regulation, so
In order to avoid the presence of such problem, the present invention by the setting of screw rod 3, and makes 3 both ends of screw rod by setting limiting device
It is connected respectively with pier shaft bent cap 1 and track girder 2, is closed so that more producing connection between track girder 2 and pier shaft bent cap 1
System, more can guarantee the safety of subsequent construction.
Preferably, heretofore described screw rod 3 is connected by connector 5 with pier shaft bent cap 1 or track girder 2；
Connector 5 is for screw rod 3 and pier shaft bent cap 1 or track girder 2, and connector 5 can use the structure of following statements here,
Bolt 53, hinge etc. can be used, the purpose that connector 5 is arranged here is exactly to realize screw rod 3 and pier shaft bent cap 1 or rail
The connection of road beam 2, problem when single screw rod 3 being avoided directly to connect with pier shaft bent cap 1 or track girder 2.
Preferably, heretofore described connector 5 passes through positioning pin 4 and pier shaft bent cap 1 or track girder 2；It is described
Connector 5 is equipped with location hole 54, and the positioning pin 4 is equipped with the nut 6 for fixedly connected part 5；The setting of positioning pin 4 is
In order to facilitate the connection of connector 5, because track girder disclosed by the invention 2 and pier shaft bent cap 1 all have biggish intensity, if
It is subsequent it is direct will appear connection difficulty big problem when connecting using connector 5 with track girder 2 or pier shaft bent cap 1, and if
Positioning pin 4 is set in advance on track girder 2 and pier shaft bent cap 1, and 4 end of positioning pin is equipped with external screw thread, so that it may the company of realization
Fitting 5 is by the connection with positioning pin 4, to realize the connection of connector 5 and pier shaft bent cap 1 or track girder 2, in this way
Structure design, simplify subsequent installation procedure, be conducive to improve working efficiency；It is simultaneously preferably, fixed in the present invention
The setting position of position pin 4 and quantity are configured according to actual requirement, because the track girder 2 of different in width and different height has
Different link positions, positioning pin 4 are also required to be adjusted according to real requirement with the position of connector 5 and quantity；The screw rod
3,4 end of positioning pin is equipped with the external screw thread for being connected with nut 6；Facilitate the connection of nut 6, it is convenient to use in practice.
Preferably, heretofore described connector 5 includes limit plate 51, the limit plate 51 is equipped with support plate
52, the support plate 52 is equipped with fixation hole, and 3 end of screw rod is equipped with connecting hole, and the connecting hole and fixation hole are set relatively
It sets, the support plate 52 passes through connecting hole by bolt 53 with screw rod 3 and fixation hole is connected；Here limit plate 51 is used for and pier
Body bent cap 1 or track girder 2 fit, and support plate 52 is vertically arranged with limit plate 51, and fixation hole, silk are equipped in support plate 52
Bar 3 is equipped with connecting hole, and the connecting hole on screw rod 3 first opens up direction and be configured as needed, and screw rod 3 can be around
Bolt 53 rotates, and designs through this structure, screw rod 3 may be implemented and be connected with pier shaft bent cap 1 or track girder 2.
Preferably, heretofore described limiting device includes at least two position-limit mechanisms, and two limits
Mechanism is symmetrical；It is at least connected on the inside of each track girder 2 there are two position-limit mechanism, two position-limit mechanisms are respectively at pier shaft lid
The two sides of beam 1, are designed through this structure, so that the connection between track girder 2 and pier shaft bent cap 1 is more convenient, but also
Connection between track girder 2 and pier shaft bent cap 1 is more stable, in embodiment, is provided with two on a pier shaft bent cap 1
Track girder 2, so a general pier shaft bent cap 1 is that there are four position-limit mechanisms for connection, in order to guarantee 1 entirety of pier shaft bent cap
Stablize, it is desirable that four position-limit mechanisms are uniformly distributed.
Preferably, heretofore described screw rod is equipped with the first connecting plate 35 close to one end of pier shaft cover board, it is described
Screw rod is equipped with the second connecting plate 34 close to one end of track girder；First connecting plate 35 and the second connecting plate 34 are mutually perpendicular to
Setting；By the setting of the first connecting plate 35 and the second connecting plate 34, so that the connection of screw rod and connector is more convenient, because
Screw rod is a round bar, there is a problem of starting through-hole in the actual operation process or threaded hole difficulty is larger, and of the invention
In by adding the first connecting plate 35 and the second connecting plate 34 avoid the above problem, to avoid above-mentioned connecting hole difficulty of processing
Big problem.
Preferably, heretofore described screw rod includes first connecting rod 31 and the second connecting rod 32, described first connects
Extension bar 31 is connected with the second connecting rod 32 by connector sleeve 33；Setting in this way, so that screw rod is one on the whole
Splicing structure, while passing through the setting of connector sleeve 33,32 relative position of first connecting rod 31 and the second connecting rod may be implemented
Connection and adjustment, while each part of limiting device being made to be to lead to subsequent assembling to form, the presence of big part is avoided, because of track
Beam is in pier shaft bent cap upper end, if limiting device is overall structure, increases the carrying difficulty of limiting device, is unfavorable for reality
Using.
Preferably, being set on heretofore described limit plate there are two support plate, it is spaced apart between two support plates, and
And the regular hexagon deep gouge for bolt positioning is equipped with close to the support plate of nut side；Regular hexagon deep gouge can be used for spiral shell
Bolt limit, avoids the occurrence of being servo-actuated when bolt fastening.
Preferably, heretofore described limit plate is equipped with T-block, institute close to track girder or pier shaft bent cap side
It states track girder and pier shaft bent cap is equipped with T-slot compatible with T-block；By the cooperation of T-block and T-slot, can play
To the position-limiting action of limit plate, facilitate the connection of connector Yu track girder and pier shaft bent cap, not only facilitates the assembly of connector fixed
Position, while position-limiting action is played, guarantee that the arrangement of connector more meets design requirement.
