Description
Technical field
The present invention relates to a kind of be used for transporting the staff and work be provided to the movable arm frame support structure that specified altitude assignment is carried out the engineering mechanical device of operation, belong to the technical field of aloft work machinery.
Background technology
The aerial lift device product category is various, differs from one another.External starting has relatively early formed a very large industry, and has set up internationalization tissue (TC214).Domestic aerial platform (platform) relies on import substantially, independent research few.At present, the jib strong point of most aerial platforms (platform) is all fixed, simple in structure like this, but its maximum operation height and collection highly all are changeless, and aerial platform (platform) requires when satisfying operation height, reduce its collection height as far as possible, be convenient to collection, transportation.For the jib strong point is the aerial platform (platform) of fixed, owing to its jib strong point is fixed, thus want to increase the length that its operation height can only increase arm, and this can make its collection length increase.
Summary of the invention
The present invention is directed to the deficiency that existing aerial platform (platform) exists, provide a kind of and can reduce the collection height when satisfying the identical operation height and satisfy identical collection can increase operation height highly the time, the while can also actv. increases the aloft work movable arm frame support structure of the maximum underground extension degree of depth.
Aloft work movable arm frame support structure of the present invention is realized by following technical solution:
This aloft work movable arm frame support structure, comprise body frame, outer trammel beam, the inner equilibrium bar, auxiliary girder and telescopic boom, the lower end of outer trammel beam and body frame are hinged by a bearing pin, the internal sleeve of outer trammel beam is equipped with the inner equilibrium bar, one end of telescopic boom, one end of auxiliary girder and the outer end of inner equilibrium bar are hinged by the jib bearing pin, the other end and the body frame of auxiliary girder are hinged, the luffing hydraulic actuating cylinder is installed on the auxiliary girder, the piston rod and the telescopic boom of luffing hydraulic actuating cylinder are hinged, be used for being connected with between outer trammel beam lower end and body frame pivotally attached bearing pin and the jib bearing pin jib bearing pin amplitude oil cylinder, body frame, auxiliary girder and jib amplitude oil cylinder are formed a triangular structure.
Be provided with the slide block that play the guiding role between inner equilibrium bar and the outer trammel beam.
The top of inner equilibrium bar is provided with a locating dowel pin, when the inner equilibrium bar is in collecting state with outer trammel beam, so that outer balance masthead is less than the jib bearing pin, protects position-limiting action.
Height when the present invention can reduce to collect when satisfying the identical operation height, can increase operation height when satisfying identical collection height, the aloft work movable arm frame support structure that simultaneously can also actv. increases the maximum underground extension degree of depth, have simple in structure, compact and reasonable, flexible good, control is convenient, the characteristics of dependable performance, ease for use is good simultaneously, maintenance, easy to maintenance.

Among the figure, 1, body frame, 2, bearing pin, 3, jib bearing pin oil cylinder, 4, the luffing bearing pin, 5, outer trammel beam, 6, locating dowel pin, 7, the inner equilibrium bar, 8, the jib bearing pin, 9, jib plate, 10, auxiliary girder, 11, telescopic boom, 12, amplitude oil cylinder frame, 13, the amplitude oil cylinder bearing pin, 14, amplitude oil cylinder, 15, auxiliary girder bearing pin, 16, the pivoting support upper plate, 17 pivoting supports.
The specific embodiment
Aloft work movable arm frame support structure of the present invention mainly comprises body frame 1, outer trammel beam 5, inner equilibrium bar 7, auxiliary girder 10 and telescopic boom 11 as shown in Figure 1.Body frame 1 is welded on the pivoting support plate 16, and in the course of the work, body frame 1 rotates with the pivoting support on aerial platform (or platform) chassis 17 with pivoting support plate 16.The lower end of outer trammel beam 5 is hinged by bearing pin 2 and body frame 1, forms rotating connection.The internal sleeve of outer trammel beam 5 is equipped with inner equilibrium bar 7, forms Collapsible structure, and outer trammel beam 5 all is the hollow rod member of square-section with inner equilibrium bar 7, is provided with the slide block (end marks among the figure) that play the guiding role between inner equilibrium bar 7 and the outer trammel beam 5.When inner equilibrium bar 7 is in collecting state with outer trammel beam 5 for 5 tops of trammel beam making outside less than jib bearing pin 8, be provided with a locating dowel pin 6(referring to Fig. 2 on the top of inner equilibrium bar 7), to protect a position-limiting action.One end of telescopic boom 11 is welded with jib plate 9, and an end of jib plate 9, auxiliary girder 10 and the upper end of inner equilibrium bar 7 are hinged by jib bearing pin 8, and the other end of auxiliary girder 10 and body frame 1 are hinged.Luffing hydraulic actuating cylinder 14 is installed on the auxiliary girder 10, and the piston rod of luffing hydraulic actuating cylinder 14 is hinged by luffing bearing pin 13 and amplitude oil cylinder frame 12, amplitude oil cylinder frame 12 and telescopic boom 11 weld togethers, and the motion of telescopic boom 11 is driven by luffing hydraulic actuating cylinder 14.Be connected with jib bearing pin oil cylinder 3 between the bearing pin 2 of outer trammel beam 5 lower ends and the jib bearing pin 8, rely on stretching of jib bearing pin oil cylinder 3 to change the position of jib bearing pin 8, make the front end of telescopic boom 11 obtain big operating altitude.Like this, body frame 1, auxiliary girder 10 and jib bearing pin oil cylinder 3 (or be sleeved on together inner equilibrium bar 7 and outer trammel beam 5) triangular structure of composition.
When work, generally can change the position of jib bearing pin 8, just jib bearing pin oil cylinder 3 remains on collecting state, when needs obtain big operating altitude, start jib bearing pin oil cylinder 3, make its piston rod elongation, one side of the triangular structure of being made up of body frame 1, auxiliary girder 10 and jib bearing pin oil cylinder 3 (inner equilibrium bar 7 and outer trammel beam 5) begins to extend like this, so that the position of jib bearing pin 8 raises, thereby reach the level height that changes jib bearing pin 8, increase the operation height of aerial platform (platform), the maximum operation height as shown in Figure 3.When needs obtain maximum underground deepening, also can make jib bearing pin oil cylinder 3 elongation, raising the level height of jib bearing pin 8, thereby change the elevation angle of telescopic boom 11, so just can obtain bigger maximum underground deepening scope of work, maximum underground deepening state as shown in Figure 4.
As shown in Figure 5, make the piston rod of jib bearing pin oil cylinder 3 regain, be in favorite places, like this can be so that the collection of whole aerial platform (platform) highly reduce, convenient transportation, storage.
But the triangular structure of employing luffing of the present invention has realized the change of jib bearing pin 8 level heights, has enlarged the zone of action of telescopic boom 11, and actv. has increased the scope of working space.Compare with the fixedly jib bearing pin of Operation Van's (platform) with identical collection height, the bigger operation height and the underground extension degree of depth can have been obtained, compare with the fixedly jib bearing pin of the Operation Van with identical operation height (platform) and to have obtained littler collection height, make compact conformation.
