The detailed description of invention
Rail brake according to the present invention is installed under the rail formula machine as hoisting crane 10.Between this hoisting crane and track, there is the space, outer rigid housing wherein is installed.The top board of this shell tightly in the downside of this hoisting crane, places the position that can use this lock with the bottom of this shell that will be adjacent to this track through the bolt bolt.Modular spring and actuator mechanism are located in this shell.Like following better description, can from this shell, remove each spring and/or each actuator through the opening in this shell, to be used for maintenance.In a kind of preferred embodiment, each actuator is mounted in a pair of actuator in this shell, to act on this spring device.This spring device comprises disc spring to 12, and this disc spring applies the downward power that is nominally 470 kNs in one embodiment to 12, with the one or more brake shoe brake cheek 14 that are installed under this spring device of downward driving.Especially, downward drive installation each brake shoe brake cheek 14 on brake-shoe lever 16 is so that its upper surface that is supporting track 18 carries out wipe contact.Each brake shoe brake cheek 14 is mounted to each brake-shoe lever 16 through bolt 16a; Thus; In case when each brake shoe brake cheek being lifted to this track top with regard to each brake shoe brake cheek of replaceable worn-down; And need not remove this shell or its any parts from this hoisting crane, wherein this bolt 16a passes the hole of metal clip 16b and engages.
In this spring device; The top of passing through to be installed, hold each spring and the rigid support at top; And especially, the spring perch 20 of the bottom through supporting each spring and the top plate member 22 that supports the top of each spring keep the spaced and parallel alignment of disc spring 12.Spring perch 20 comprises forming and is used for wall 20a and cylindrical locking member or the guiding piece 20b of vertical stand-up of the bottom cover of each spring 12 in taking a seat; This locking component or guiding piece 20b extend upward in the chamber that is limited each wall 20a; So that each spring 12 is installed in the spring perch 20, and upwardly extending guiding piece 20b passes center and the axle journalization of the spiral coil of each spring.When each spring 12 was compressed as is further described fully, the end face of guiding piece 20b was adjacent to the downside of top plate member 22.Because the overdraft of each spring possibly damage each spring, center guiding elements 20c extends upward between each spring, and is against and serves as stop part (stop) on the top plate member 22, to prevent the overdraft of each spring.Dottle pin is served as at the top of center guiding elements 20, and it combines to prevent overdraft with this top board.
The strut member of each spring 12 and each spring of being provided by the spring frame as spring perch 20 all is installed in the outer rigid housing 26.Shell 26 is installed in the downside (the for example downside of hoisting crane 10) of this rail formula machine, in the downside and the space between this track of rail formula machine.Top plate member 22 fastens on the dottle pin 22b of the upper plate 26a downside that is installed in shell 26 through bolt.Shell 26 comprises upper plate 26a, sidewall or supporting frame 26b (being referred to as wall at this) and rigid base 26c, and this rigid base 26c is supported on this upper plate 26a downside by each wall rigidly.This spring assembly by spring to 12, spring perch 20 and top plate member 22 form; Be installed in this shell 26; Make in case removed this brake shoe assembly and through removing each bolt 30 this spring top plate member 22 has been separated bolt from each the dottle pin 22b below the upper plate 26a; Just can remove this spring assembly from the opening (promptly through the opening the spring wall) of this shell one side.
Between the upper plate 26a of top plate member 22 and shell 26, keep chamber or space 28 through each dottle pin 22b.Space 28 allows each stop pin 24 (being the upper end of each Lock Part) to carry out vertical lift.Through each bolt 30 that passes each dottle pin 22b with these top plate member 22 bolts tightly in this upper plate 26a, this spring assembly is suspended in the shell 26, with compression and the stretching, extension of holding each spring 12.Promote spring perch 20 downwards along with the stretching, extension of each spring 12 so that brake shoe brake cheek 14 biased downward, and with at track 12 wipe contacts.This pedestal 26c of this shell and for example cantilevered or other form, installation of driver is to 32 between the load bearing component such to 20c from the rigid flange of spring perch 20 horizontal expansions, this actuator can be hydraulic unit driver to 32.When driving when extending this driven plunger, each actuator 32 is operating spring seat 20 upwards.This will compress each spring 12 towards the compression latched position fully of each spring 12, and each brake shoe brake cheek 14 is raised to track 18 tops.Along with spring perch 20 is elevated, stop pin 24 also is elevated, in the space 28 above the respective upper surfaces that the head 24b on the handle 24a is promoted to top plate member 22.
Along with each spring is compressed by each actuator fully, for example when the driven plunger stroke of given about 10mm, head 24b also will be raised to by same stroke in the space 28 of respective upper surfaces top of top plate member 22.Move in order laterally to slide, on even keel is installed the lock or the door bolt of the door bolt parts that for example comprise that fork 34 is such, and it has and is substantially equal to the thickness that this stroking distance leaves, and places with each tooth 34a that will pitch under the annular lip of head 24b of this stop pin.Head 24b can form and comprise annular lip, edge or lasso, to engage with each prong.Can come manual actuation fork 34 by means of for example handle or pin 34b.When each spring 12 compresses fully, but on even keel pushing pin 34b inserts head 24b below will pitch 34.Each spring 12 of insertion lockable of each tooth 34b of the fork 34 of head 24b below is to rest in each brake shoe brake cheek at the elevated position place of track 18 tops.Then, can remove each brake shoe brake cheek in order to check, to keep in repair or changing.Discharge each brake shoe brake cheek in order to raise from it with stop position; Each actuator full extension; Further slightly each spring 12 is compressed to unlocked position; For example, surpass the nominal piston stroke 2mm of 10mm again, thus through raising head 24b the spring force load is removed from pitching 34 from pitching 34 slightly.Then, can fork 34 be taken out the 24b below from the head.Then, can take out each actuator piston, thereby allow to stretch each spring, so that this brake shoe brake cheek props up this track with this piston stroke distance.
In the superincumbent example that does not provide constraints; And shown in Fig. 3 a-3e; The given piston stroke nominal range of 10mm; In case each spring from being compressed, can use another compression distance (for example further compressing 2mm) with the stroking distance of 10mm, with head 24b below discharging pallet 24 from this stop pin.In addition, when each spring with the stroking distance of for example 10mm when extending, each spring also should be able to carry out the for example further stretching, extension of 2mm, the fluctuation when raising with respect to shell 26 to adapt to track 12.Therefore, for example, in the scope of positive and negative 2mm, this brake shoe brake cheek should be able to vertical lift, and the power that still on this track, keeps down simultaneously, and this power is enough to provide and suppresses the braking function of this rail formula machine along this orbiting motion.In order to provide an example of the power that is applied by each spring, each spring can provide the nominal force of 270 kNs, and maximum, force is about 300 kNs, and this example does not provide constraints.Therefore, spring is to providing the power of nominal 540 kNs.Therefore, for these two springs, be nominal 540 kNs in order to compress each spring power required, that upwards apply by these two actuators, and be about 600 kNs to the maximum.Like what see among Fig. 3 a; Each spring compress brake release position fully corresponding to this spring assembly; In this position, this brake shoe brake cheek is lifted to this track top 10mm, and this spring is compressed with the piston stroke of 10mm; For the length in described example is the spring of 330mm, and this almost is to be compressed to its maxim.
In an illustrated embodiment; In this brake release position; This shell and spring assembly are made by certain size; So that the gap " a " of 17mm to be provided between the pedestal 26c of the bottom of spring perch 20 and this shell; The gap " c " of 4mm is provided between the downside of the top of stop pin 24 and upper plate 26a, and between the top of the bottom of pedestal 26c and track 12 and between the top of the bottom of upper plate 26a and top plate member 22 the full extended position expansion " d " of 23mm and standoff distance " f " and " g " of 57mm is being provided respectively.
Lock at Fig. 3 b is provided with in the position, and through the retraction of each actuator piston, each spring, so that the downward cluster spring power of 540 kNs to be provided, thereby is pressed on this brake shoe brake cheek on this track from extending with the nominal stroking distance of 10mm.Thus gap " a " is reduced to 7mm; With the corresponding 340mm that extends to of spring length " b "; " c " extends to 14mm with the gap; Cylinder piston expansion " d " is reduced to 13mm, the gap " e " between this track and this brake shoe brake cheek is reduced to nominal zero, and among standoff distance " f " and " g " each is remained identical 57mm.The holding force of this rail brake is the function of the friction coefficient between this brake shoe brake cheek and this track.For hard zig-zag brake shoe brake cheek, this friction coefficient can be 0.5 of nominal, provide thus be nominally 270 kNs, along the holding force of this track.
The lock that Fig. 3 c shows in following situation is provided with the position: for example, the height of track upwards departs from 2mm, makes that the stroke of the 10mm under spring travel and the nominal orbit altitude is different; Become 8mm, make this gap " a " become 9mm, spring length " b " becomes 338mm; " c " becomes 12mm in the gap; And cylinder piston expansion becomes 15mm, because this track departing from height, and the height of this brake shoe brake cheek 2mm that upwards squints.In this position, spring force is approximately 484 kNs.
Fig. 3 d shows the example opposite with Fig. 3 c, wherein shows lock the position is set, and in this position, this track deviation is the orbit altitude 2mm that is lower than this nominal, makes that this spring travel is 12mm rather than 10mm.Therefore, gap " a " is 5mm, and spring length " b " is 342mm, and gap " c " is 16mm, and cylinder piston expansion " d " is 11mm.Total spring force between two springs is about 456 kNs.In this example, the maximum functional stroke of each spring is 16mm, and this shell makes by certain size, makes this spring assembly be in this shell at the stroke of 17mm and drops to bottommost.
At the rim lock allocation place of Fig. 3 e, fork 34 has been inserted into the below of the head 24b of stop pin 24, and each actuator 30 retraction; Thus; " b " is the spring of 332mm for length, makes its heavy elongation 2mm, pitches and locks each spring thereby prop up this downwards through the head that makes this stop pin.Therefore, gap " a " is reduced to 15mm, and the retraction (for example the retraction of 6mm stretches) that gap " c " expands " d " owing to cylinder piston increases to 6mm.
In view of above-mentioned open, will to those skilled in the art conspicuous be under the situation that does not exceed the spirit and scope of the present invention, can in practice of the present invention, carry out many changes and modification.Therefore should explain scope of the present invention according to the following purport that claim limited.
