Abstract
The utility model relates to a hydraulic excavating machine turn table body which comprises an integral type bottom plate (1), a left longitudinal beam (5), a right longitudinal beam (2), a vertical plate (4), a strengthening rib plate (7), an upper seat plate component (3), a middle seat plate (8) and a lower seat plate (6). The bottom plate (1), the vertical plate (4) and the longitudinal beam are welded to form an open box-shaped structure; the lower seat plate (6), the middle seat plate (8) and the upper seat plate component (3) are welded on the vertical plate (4), the left longitudinal beam (5) and the right longitudinal beam (2); through holes are drilled on the bottom plate (1), the lower seat plate (6), the middle seat plate (8) and the upper seat plate component (3), and are used for installing a deflexion device of an excavating machine movable arm. The utility model has simple structure, reasonable layout and small volume of occupied space, and is convenient for layout and assembly of parts of excavating machine hydraulic pieces, a power device, and the like.
Description
Technical field
The utility model relates to a kind of hydraulic crawler excavator turntable main body, and this turntable main body not only intensity can satisfy instructions for use, and simple in structure, shared spatial volume is little and be convenient to the layout and the assembling of component such as excavator hydraulic part, power set.
Background technology
Existing excavator turntable main body with tonnage, generally form by base plate, left longeron, right vertical beam, left longeron stiffener, right vertical beam stiffener, riser, upper base plate assembly, middle seat board, following seat board, reinforcement gusset, crossbeam, back transverse slat, wherein left and right longeron is made by shaped steel, in order to satisfy the requirement of strength of turntable, need increase left longeron stiffener and right vertical beam stiffener respectively by the mode of welding in the outside of left and right longeron, simultaneously owing to be subjected to the restriction of base arrangement, for other component of excavator are installed, also need to increase crossbeam and back transverse slat.Existing turntable agent structure complexity, shared spatial volume are big, and particularly left longeron and right vertical beam height are very high, and not only the manufacturing cost height has also seriously restricted the layout and the assembling of component such as excavator hydraulic part, power set.
Summary of the invention
The purpose of this utility model is to provide a kind of not only intensity can satisfy instructions for use, and simple in structure, shared spatial volume is little and be convenient to the layout of component such as excavator hydraulic part, power set and the hydraulic crawler excavator turntable main body of assembling.This structure has well solved existing mini-excavator turntable agent structure complexity, shared spatial volume is big and be unfavorable for that component such as excavator hydraulic part, power set are arranged and the problem of assembling.
Technical solution of the present utility model is such, comprises longeron, riser, reinforcement gusset, upper base plate assembly, middle seat board, the following seat board of base plate, two symmetries.Feature is: the centre of gyration is installed rotary body on the base plate face, in the base plate both sides left longeron, right vertical beam are installed, seat board under the installation of base plate the place ahead, install and strengthen gusset, strengthen on the gusset face seat board in install between the riser front, the riser end face is installed base plate assembly, on upper base plate assembly, middle seat board, following seat board, the base plate vertical central lines through hole is arranged.
Hole and profiled holes are opened in base plate front end and centre, open profiled holes in the and arranged on left and right sides of bottom end plate, the equal bevel in both sides inside and outside the bottom of left longeron and right vertical beam, and riser and base plate, left longeron and right vertical beam are formed the box-structure of an opening.
The utlity model has simple in structure, connection and reasonable arrangement, shared spatial volume is little, reliable and stable, and is easy to operate and be convenient to advantages such as the layout of component such as excavator hydraulic part and power set and assembling.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is the vertical view of hydraulic crawler excavator turntable main body of the present utility model.
Fig. 2 is the left view of the utility model Fig. 1.
Fig. 3 is the A-A sectional view of the utility model Fig. 1.
In Fig. 1～3: base plate (1), right vertical beam (2), upper base plate assembly (3), riser (4), left longeron (5), following seat board (6), reinforcement gusset (7), middle seat board (8), through hole (9), profiled holes (10), profiled holes (11), groove (12).
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to accompanying drawing 1～Fig. 3, open hole (9) and profiled holes (10) at base plate (1) front end and middle appropriate location, data given when its position is designed by the excavator complete machine are determined, and arranged on left and right sides and afterbody at base plate (1) are opened profiled holes (11), mainly are in order to alleviate the weight of unitary underframe (1); Left side longeron (5) and right vertical beam (2) launch the appearance and size blanking by it earlier, bending and molding again, in order to improve the connection reliability of left longeron (5) and right vertical beam (2) and base plate (1), at the inside and outside equal bevels in both sides (12) in the bottom of left longeron (5) and right vertical beam (2); The turntable main body is found out the centre of gyration of turntable by auxiliary mould on base plate (1) when welding fabrication, be benchmark with the centre of gyration again, determines the welding position of left longeron (5) and right vertical beam (2); Riser (4) and base plate (1), left longeron (5) and right vertical beam (2) welding form the box-structure of an opening; Requirement for height when seat board (6) is installed to satisfy the excavator swing arm arrangement for deflecting under the welding of base plate (1) front end; For the intensity of seat board in improving (8), thereunder weld two and strengthen gusset (7); Upper base plate assembly (3) then is welded to riser (4), left longeron (5) and right vertical beam (2) upper surface, and after the turntable main body welding, the through hole that guarantee the through hole of upper base plate assembly (3), middle seat board (8) and base plate (1) and following seat board (6) is on same axis.
Claims (2)
1, a kind of hydraulic crawler excavator turntable main body, comprise all-in-one-piece base plate, longeron, riser, strengthen gusset, the upper base plate assembly, middle seat board and following seat board, it is characterized in that the centre of gyration is installed rotary body on base plate (1) face, in base plate (1) both sides left longeron (5) is installed, right vertical beam (2), seat board (6) under the installation of base plate (1) the place ahead, install and strengthen gusset (7), strengthen on gusset (7) face seat board (8) in install between riser (4) front, riser (4) end face is installed base plate assembly (3), upper base plate assembly (3), following seat board (6), on base plate (1) vertical central lines through hole (9) is arranged.
