Abstract
The utility model disclose a turnover window of a driver cabinet for an engineering machine, which comprises a turnover window assembly (11), wherein a lifting fixed track (3) is arranged at a turnover window cam assembly (2), a telescoping rocker-arm connecting rob (8) is formed by sleeve jointing of a fixed plate (1) and an active plate (5), and the fixed plate and the active plate can be moved relatively under the external force action. An end of the fixed plate (1) removed from the active plate (5) is connected to the turnover window cam assembly (2) via hinge while an end of the active plate (5) removed from the fixed plate (1) is connected to the turnover window assembly (11) via hinge, an end of the active plate (5) near the fixed plate (1) is in sliding connection with the lifting fixed track (3) on the turnover window cam assembly (2), one end of a gas spring (6) is fixed and the other end is connected to the fixed plate (1) via hinge. The turnover window is a driver cabinet for an engineering machine, which is simple in structure, convenient in production and reliable in performance, further the driver can not hit the head when the turnover window is open normally in position or normally closed.
Description
Technical field
The utility model relates to a kind of drivers' cab tilting window of engineering machinery.
Background technology
The drivers' cab front portion of engineering machinery is shaped to the streamline orthodrome at present, and this tilting window top and operator's head severe interference (" meeting and discussing ") when the greatest problem that its tilting window exists at present is unlatching could be realized the tilting window unlatching after the operator must bend over, bow.Numerous domestic engineering machinery drivers' cab manufacturer all fails effectively to address this problem.And abroad some adopt the upset of stationary links activity window why can not meet and discuss, and reason is relevant with outage degree in moulding of its driver's cabin own and the driver's cabin integral body, and moulding directly influences the position and the angle of inclination of slide rail, and the influence of interior outage degree also is clearly.
In fact present tilting window is the he Moving Leader Mechanism that develops and in the quadric chain, with first twisted point is center of rotation; rocker-arm link is radius (distance between first twisted point and second twisted point), and drive activity window is that fulcrum moves back and forth in slideway with the 3rd twisted point.Owing to be subjected to the moulded restriction of drivers' cab, and configuration aspects is not done under the big adjustment prerequisite, its slideway is fixed, the first twisted point position basic fixed, must assurance under the activity window opening and closing situation about all putting in place, if rocker-arm link is rigidity (on-telescopic), the movement locus of the movable window of glass is unique.Be subjected to the rocker-arm link length restriction, tilting window is in switching process, and its tip position and drivers' cab distance from top are excessive, surpasses 30cm, and be about 20cm, so in operating process, " meet and discuss " with its head distance driver's cabin top of operator's normal sitting position of height 175cm.
Simple adjust the length of rocker-arm link and change the first twisted point position, movable window or can not normally open and put in place, or can not normally close, all can not head it off.
The utility model content
Technical problem to be solved in the utility model provides a kind of engineering machinery drivers' cab tilting window that all can not meet and discuss when normal unlatching puts in place or normally closes.
In order to solve the problems of the technologies described above, the engineering machinery drivers' cab tilting window that the utility model provides, comprise the tilting window assembly, the tilting window Cam set assembly is provided with the lifting trapped orbit, telescopic rocker-arm link is made up of fixed head that can do relative motion under external force between the two and portable plate socket, described fixed head is hinged away from the end and the described tilting window Cam set assembly of described portable plate, described portable plate is hinged away from the end and the described tilting window assembly of described fixed head, described portable plate closes on the end of described fixed head and the lifting trapped orbit on the described tilting window Cam set assembly is slidingly connected, air spring one end is fixed, and the other end and described fixed head are hinged.
Adopt the engineering machinery drivers' cab tilting window of technique scheme, change rocker-arm link into extension type between the two by being rigidly connected originally by fixed head that can do relative motion under external force and portable plate socket, the tilting window Cam set assembly is provided with the lifting trapped orbit, after tilting window is opened, air spring promotes in the telescopic rocker-arm link fixed head and does circular motion along twisted point, the portable plate one end orbiting motion that must in promoting trapped orbit, fix in the telescopic rocker-arm link simultaneously, along with the lifting that promotes position in the trapped orbit changes, drive activity window (with portable plate hinge joint in the telescopic rocker-arm link) increases a lifting action that makes progress when moving in a circle, make the movable window of glass when the upset beginning, have one upwards to promote and add rotating action, thus contention problem when the realization of this complex superposition action efficiently solves upset.As can be seen, how many tilting windows upwards promotes the amplitude size, in theory fully by promoting trapped orbit control.
In sum, the utility model is a kind ofly to put in place or all can not meet and discuss and engineering machinery drivers' cab tilting window simple in structure, easily manufactured, dependable performance when normally closing normal the unlatching.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model closed condition schematic diagram;
Fig. 2 is the utility model open mode schematic diagram.
The specific embodiment
Referring to Fig. 1 and Fig. 2, in drivers' cab 4, be provided with both sides and be provided with tilting window Cam set assembly 2 relatively, tilting window Cam set assembly 2 is provided with and promotes trapped orbit 3, in drivers' cab 4, be provided with guide rail 10 and be installed on tilting window assembly 11 in the guide rail 10, telescopic rocker-arm link 8 is made up of fixed head 1 that can do relative motion under external force between the two and portable plate 5 sockets, fixed head 1 is hinged away from the end and the tilting window Cam set assembly 2 of portable plate 5, portable plate 5 is hinged away from the end and the tilting window assembly 11 of fixed head 1, portable plate 5 closes on the end of fixed head 1 and the lifting trapped orbit 3 on tilting window cam 2 assemblies is slidingly connected, air spring 6 one ends are fixed in the support, and the other end and fixed head 1 are hinged.
Referring to Fig. 1 and Fig. 2, its operating principle is:
Telescopic rocker-arm link 8 is made up of fixed head 1 and portable plate 5, can do relative motion under external force between the two.After tilting window assembly 11 is opened, fixed head 1 is done circular motion along the fixed head 1 and the hinge rotation of tilting window Cam set assembly 2 in air spring 6 (with 1 hinge joint of fixed head in the telescopic rocker-arm link 8) the telescopic rocker-arm link 8 of promotion, simultaneously portable plate 5 one ends are fixed in are promoted trapped orbit 3 orbiting motion that must fix in promoting trapped orbit 3 in the telescopic rocker-arm link 8, along with the lifting of portable plate 5 with the position that promotes trapped orbit 3 twisted points changes, drive tilting window assembly 11 (with 5 hinge joints of portable plate in the telescopic rocker-arm link 8) increases a lifting action that makes progress when moving in a circle, thereby the realization of this complex superposition action efficiently solves contention problem when overturning.As can be seen, how many tilting windows upwards promotes the amplitude size, in theory fully by promoting trapped orbit 3 controls.
