Description
Walking type tamping tool involved in the present invention has one to be bearing in frame on the running mechanism and one and can to make the tool rack of sideshake being parallel to orbital plane around a vertical axis, in addition circuit tamping unit laterally is housed side by side, utilize driving mechanism can be separately separately laterally and move up and down.Tamping unit is equipped with the pairing pickaxe arm that can smash into the tamping pickaxe of ballast aggregate that has that utilizes driving mechanism opening and closing and vibration.
According to the walking type tamping tool with above-mentioned feature of the present invention for same patent applicant and the holder of patent's No. 3534687 patent introductions of US-PS, known, this tamping tool have two make that the equipment carrier is contained in firm by ramming can sideshake and can be on the tool rack that freely stretches out according to the operator.In order to make two adjacent sleepers simultaneously firm by ramming, make firm by ramming on the equipment carrier according to vertical front and back of circuit the track lining device that two cover tamping units and a cover corrector are used is housed.Every cover tamping unit be equipped with utilize driving mechanism to regulate height and make it opening and closing and vibration make leg in pairs firm by ramming, be equipped with above and can smash on the left of a certain one steel rail and the tamping pickaxe of right side ballast aggregate.Two carriers utilize driving mechanism to go up laterally and to move by each comfortable tool rack (can center on a vertical axis lateral rotation to frame).Employing is located at tamping unit on the frame of stretching out, exactly be contained in can sideshake tool rack on the tamping tool of the compact structure that adopts usually of this old-fashioned machinery, in order to make it also to make track switch firm by ramming, the single leg and the cover baseline system of making firm by ramming of lateral rotation separately is housed, forms the levelling tamping tool jointly.
According to the another kind of known close-coupled tamping tool that the US-PS-3426697 patent is introduced, its tamping unit adopts and stretches out form, is contained on the tool rack of an energy to the frame sideshake.Tamping unit is totally two covers, and every one steel rail is equipped with a cover and can laterally moves separately separately, and it highly can be regulated.This two covers tamping unit is installed in one and stretches out machinery foremost on the traversing guide rail of the elongation formula tool rack beyond the running mechanism, can regulate height and lateral attitude.Utilize driving mechanism can make tool frame to frame around a vertical axis sideshake, make the pick arm can adapt to the rail distance that constantly changes in the track switch better.This structural cost is higher, because the tool rack of energy sideshake must here be fixed by sliding bearing then through to the back of whole frame, exactly is bearing on the frame, and tool rack can be swung.Other shortcoming is together to move makes leg firm by ramming and can not accurately align the sleeper that will make firm by ramming, because certain distance is arranged between the center of the rotating shaft position of tool rack and traversing guide rail.This distance has been brought such shortcoming, exactly owing to cooperate bad pick arm not parallel with crooked sleeper exactly, so tamping sleeper and make it to keep for a long time exactly just.
According to making the levelling track lining machine firm by ramming for the so-called close-coupled of the another kind of walking type tamping mechanism of the same patent applicant and the holder of patent's US-PS4625651 patent with the present invention.Over nearly 20 years, the machinery of the above-mentioned elongation formula of this mechanical ratio structure is proved to be more reliable, because with tamping unit with play a track lining device and be located between the running mechanism of apart from each other, and corrector absolute altitude and lateral position more accurately.In addition, because the running mechanism apart from each other can make the deflection of rail comparatively relax, thereby avoid rail to bear unallowed flexural stress.This tamping tool is that every one steel rail is provided with the tool rack that being equipped with of oneself made the track lining device firm by ramming.One end of the tool rack that each can be swung, hinged by an adjustable length linkage and frame, the other end (end relative with pin joint) has a single free support formula guiding running mechanism, is used for traveling on an one steel rail.This track lining device system of having made firm by ramming is referred to as so-called track switch trimming device, and it is equipped with pick arm and the track lifting clamp and the band edge track lining roller of energy sideshake, is used to rebuild switch area and zone similarity.
According to a kind of tamping tool that the modern architecture tamping unit is housed of introducing for No. 4576095 patents of US-PS US-PS of same patent applicant and the holder of patent with the present invention, known.It has two cover tamping units, and every one steel rail is equipped with a cover, utilizes driving mechanism laterally to move separately, and the paired pick arm of two bodies that can smash into rail left side or right side ballast aggregate is housed simultaneously.Independently make the unit firm by ramming in order to form, every pair of pick arm can be regulated height respectively.Like this, the switch section of difficulty of track obstacle is being arranged, also can fall the unit of making firm by ramming of the relative side of an one steel rail, successfully making firm by ramming.
In addition, the tamping tool of a kind of reach structure of being introduced according to GB-OS 2201178A patent, known.The driving mechanism that this machinery is equipped with quadruplet utilization oneself can be regulated the unit of making firm by ramming of height and lateral attitude respectively.The machinery of this reach structure does not play the track lining device, is used for the corrector position.Described as first claim explanation in No. 3669025 patents of US-PS and No. 4445437 patents of US-PS, the every one steel rail in unit of making firm by ramming that this class can be regulated is equipped with two covers, all quadruplets can be regulated making firm by ramming on the rack-mounted guide frame structure in unit of height respectively, utilize the driving mechanism of oneself can distinguish laterally mobile.With this known quadruplet can regulate respectively height and lateral attitude make firm by ramming the unit (respectively be equipped with a pair of pick arm be used to smash on the left of a certain one steel rail and the ballast aggregate on right side), can strengthen the trimming scope of switch section, but sleeper pitch is inhomogeneous or when crooked sleeper was arranged, one-tenth can not satisfy the very high request that the corrector position precision is proposed.
Purpose of the present invention will be created a kind of this paper exactly and start described walking type tamping tool, require this mechanical energy at difficult track section, such as at switch section, or on sleeper circuits crooked or that sleeper pitch is different, use, the pick arm that requires machinery simultaneously can be rapid, easy and adapt to the operation process of smashing into ballast aggregate exactly.
This task starts described walking type tamping machine according to the invention with this paper and solves like this, the driving mechanism that is arranged side by side according to the circuit transverse horizontal exactly, utilize oneself is regulated highly, respectively is equipped with the quadruplet of a pair of pick arm (having the tamping pickaxe that can smash certain one steel rail left side and right side ballast aggregate) respectively and makes firm by ramming in the unit, the at least two cover outsides are made the unit firm by ramming and are highly regulated driving mechanism, be contained in a driving mechanism that utilizes oneself respectively, can be on the swing type tool rack of a vertical axis, so that can lateral adjustments to the frame sideshake.
Utilize this very simple but structurally very firm novel basic structure, layout of making the unit firm by ramming and independent mobile problem that quadruplet can move separately separately simply and have very advantageously been solved, even thereby simultaneously by rationally install this quadruplet single make firm by ramming the unit kept when the more difficult switch section also can continuous operation advantage, and improved compliance more to sleeper.Adopting the outside of special mounting means that can teeter to make the unit firm by ramming to the major general is contained in respectively on separately the swing type tool rack, can create and a kind ofly can bear top load, simple in structure and method of attachment frame, and because oneself tool rack and lateral rotation mechanism are arranged, thereby strengthened the independence that every cover is made the unit firm by ramming, so that on purpose adapt to various track obstacles separately owing to have at least the two cover outsides to make unit sideshake separately firm by ramming, the pick arm is adapted to, centering exactly, be positioned on the siding so that make firm by ramming, but the sleeper bearing surface of the switch section that also links to each other with main track by common long sleeper.The centering process that adopts this way that operating personnel are observed well to make the unit firm by ramming, and opening and closing and smashing into the total situation of ballast aggregate process.Configuration aspects is especially simply also shown in order to make the outside make unit sideshake well firm by ramming, does not need to be provided with width and exceeds building near circle, boundary and the cross slide way (comprising bearing) that links to each other with frame.Making the two cover outsides firm by ramming unit is fixed on and can smoothly and promptly its pendulum be got back to building on the swing type tool rack and connect and pay in the gauge scope.
A special superior structural form of the present invention is: the end that the unit is installed in swing type tool rack is separately respectively made in the two cover outsides firm by ramming, and the place that the unit borders on is made in the swing type tool rack of each elongate form and the outside firm by ramming, also be bearing in a horizontal slideway on the frame extraly, exactly on the guide rail.This elongation and the protruding-type structure of swing or tool rack provide quite wide lateral adjustment scope for making the unit firm by ramming, make to make the unit energy firm by ramming smoothly, simply and uninterruptedly make main track and siding simultaneously firm by ramming.Because each swing type tool rack is bearing on the guide rail extraly, thereby can guarantee to make firm by ramming the unit and be in any swing position the time, reliable supporting is arranged all.Make the unit firm by ramming and be installed in the end of swing type tool rack, can make the unit firm by ramming with every suit outside at the relative end of pin joint and align sleeper rapidly and exactly, exactly can observe every pair of pick arm to a great extent well.This point has special meaning for the switch section of making various track obstacles (as protecting turbine, connecting bar etc.) firm by ramming, because in the place of this class difficulty, operating personnel want high concentration spirit when working, to avoid damaging track.
A very favorable superior structural form of the present invention is: make the unit firm by ramming according to each tool rack and the outside thereof of operator in the free elongate form swing type tool rack that is located immediately at a running mechanism front for two, can swing outwardly around a vertical axis side direction that approximately is positioned at a certain one steel rail top, leave the inboard and make the unit firm by ramming.Adopt this freely giving prominence to and two swing type tool racks of elongate form, can make the outside make unit side direction in sizable total hunting range firm by ramming and regulate and move, easy and successfully make place by the circuit firm by ramming, particularly make siding firm by ramming.The swing type tool rack adopts two rotating shafts, can simplify its structure and bearing method, and any interference can not take place each other.
A good improved project of the present invention is: make inboard between the unit in the two cover outsides firm by ramming and make the unit firm by ramming and highly regulate driving mechanism and be installed on the frame, or be installed on the instrument carrier bar that is connected with frame.Making the inboard firm by ramming unit makes the unit firm by ramming with the outside and separates the mode of installing separately, its advantage is to make firm by ramming the outside of leaving track section far away (particularly siding) usefulness and makes the unit firm by ramming, can use the simplest method, be not subjected to the inboard to make the influence of unit firm by ramming, in a very big scope, move together separately, exactly carry out centering with the swing type tool rack.The inboard was made the unit firm by ramming and was carried out operation in the scope between as usual can be in the line this moment.Make the inboard firm by ramming unit and be installed on the frame or on the tool rack of oneself, can make firm by ramming under the influence of unit not being subjected to the outside, according to different type of machines trimming track switch and/or circuit.Make the unit firm by ramming for two kinds and adopt different mounting methods to also have such advantage, its weight load can be distributed on two different sections of frame exactly.
A good and favourable form of structure of the present invention is: between two swing type tool racks, exactly make firm by ramming between the unit rack-mounted in the two cover outsides, or the inboard that is installed on the instrument carrier bar is made the unit firm by ramming and is highly regulated driving mechanism, by means of cross slide way and the driving mechanism of oneself, can be separately separately to the frame lateral adjustments.The inboard is made the unit firm by ramming and is taked this mounting method, and just can not being subjected to the outside to make any of unit firm by ramming separately individually again influences, and laterally moves with the easiest method, thereby adapts to rapidly and exactly, exactly aligns various track obstacles.This moment, cross slide way itself can successfully be installed in for very big horizontal moving range in the structure clearance, did not also disturb the outside that links to each other with the swing type tool rack respectively to make the unit firm by ramming simultaneously.The outside and inboard are made the unit firm by ramming and are taked this different mounting method, also can alleviate cross slide way well and bear because of tamping pickaxe and smash the caused load of sizable resistance that produces into ballast aggregate rapidly.
A good especially improved project of the present invention is: instrument carrier bar and the two cover inboards of regulating are separately separately highly made unit and cross slide way and two horizontal mobile driving mechanisms etc. firm by ramming, be installed on the frame, utilize the driving mechanism of oneself, can center on one and pass the vertical axis of making unit transverse vertical plane and mechanical longitudinal axis firm by ramming, be parallel to orbital plane and rotate.This mounting method that can rotate of instrument carrier bar has special advantage, and the inboard unit of making firm by ramming of two covers can also center on a vertical rotational except that keeping the function that laterally moves separately separately exactly.Under the situation that increases structure slightly, just the tamping pickaxe that can make the inboard make the unit firm by ramming is adjusted to the state that parallels with crooked sleeper like this, and can carry out corresponding horizontal moving simultaneously, aligns the place that will make firm by ramming exactly.Apart from track centerline place far away, particularly reach the place of siding, then make cell processing firm by ramming with the outside.Need this moment such as sideshake instrument etc., makes it to reach corresponding sleeper or location of rail.Under so just can situation, even the most difficult switch section (many various track obstacles being arranged, particularly the obstruction of switch blade rail form) is made firm by ramming or proofreaied and correct with method rapidly and the identical tamping quality of maintenance.In addition, adopt the inboard to make this specialized structure that the unit is not equipped with the rotary type tool rack of oneself firm by ramming, just might arrange individually, in the clear, more simply to a great extent and make two swing type tool racks that the unit links to each other firm by ramming with the outside.
Another good form of structure of the present invention is: the unit is made in the outside of every cover energy lateral rotation firm by ramming and supporting inboard is made the unit firm by ramming, its outside respect to one another is laterally protruding according to circuit, inboard respect to one another is linear basically, then is mirror-symmetrical to the rail plane of symmetry.Adopt this special dissymmetrical structure to make very near that the unit arranges mutually firm by ramming with a cover outside and a cover are inboard, make operating personnel be convenient to observation, and can make the crosspoint of rail and sleeper in the clear simultaneously firm by ramming.
Of the present invention one especially practicality with good form of structure be: make with the outside that the unit links to each other and be parallel to the orbit plane bending firm by ramming for two, be each tool rack in the swing type tool rack of dihedral in other words, its vertical axis is made the unit firm by ramming to the outside distance is about 4 to 5 meters at least, approximately is 2 to 3.5 gauges in other words.Utilize separately corresponding driving mechanism to make to make the total hunting range in unit firm by ramming and reach about 1.7 meters.Two swing type tool racks adopt the structure of this not special elongate form, add and be bearing in securely on the frame, make the outside make the unit firm by ramming and reach sizable total hunting range, can not produce difficulty technically, in the frame scope, supported with good method, can avoid the time and labor of overspending to go to reequip, can reach the purpose of supporting.This moment, each tool rack can reach the maximum exactly maximum pendulum angle of moving range, sleeper crooked when more serious also in this way.
Good especially form of structure of the present invention is: the vertical axis of each swing type tool rack, according to the operator to being positioned at after the outside makes the center line of running mechanism of back, unit firm by ramming, exactly be positioned at one of pivoted frame near making the turning in the middle of the posture after the running mechanism of unit firm by ramming, adopt this structure can make the swing type tool rack be bearing in securely in the middle of on the running mechanism, simultaneously by the bogie of this running mechanism with tool rack with make firm by ramming on distribution of weight to two axletree of unit.Because frame is a radial type, thereby driver's cabin can be removed from middle running mechanism, make two swing type tool racks and driving mechanism thereof can not be subjected to any obstruction ground to arrange and install.
A very good improved project of the present invention is: the two cover outsides are made the unit firm by ramming and are highly regulated driving mechanism, in the scope of the swing type tool rack end on vertical axis opposite, can also rotate around another root vertical axis, link to each other with driving mechanism respectively simultaneously, so that rotate towards track centerline, exactly make unit rotational firm by ramming towards corresponding inboard.The swing type tool rack adopts this dual articulated manner, just can make inconvenient switch section firm by ramming, and under the unrestricted situation of above-mentioned advantage, the unit is made in the sideshake outside firm by ramming separately, makes inconvenient switch section firm by ramming to adapt to greatest extent.Should go the sleeper bearing surface of making firm by ramming in order to align exactly, can utilize second vertical axis to adjust tamping pickaxe exactly, make it to reach and the position that vertically parallels of crooked bolster (to make the outside firm by ramming put the unit lateral position irrelevant with first vertical axis).So just can make rapider more accurate this class of making firm by ramming more equably in unit firm by ramming and relatively be difficult to the crooked sleeper of making firm by ramming, the place of various track obstacles is especially arranged in conjunction with the inboard.An advantage of this respect is: this dual hinge method of swing type tool rack only increases limited content in configuration aspects.
Another design feature of the present invention is: to outstanding forward by its vertical axial, and it is directly and slideway according to the operator for the swing type tool rack of each elongate form, the free end that joins with guide rail in other words, and then to make the unit firm by ramming hinged with the outside.Make the outside firm by ramming unit and be located at the outstanding free end of swing type tool rack, its advantage is that operating personnel can have better, wherein go up the sight line that is not subjected to overslaugh, to observe, make whether quickly and accurately centering (the particularly switch section beyond circuit) of unit outside exactly checking firm by ramming.With slideway, exactly guide rail directly is installed in and makes the next door, unit firm by ramming, can also be under swing type tool rack no-load situation, the unit is made in supporting firm by ramming especially securely.
