Abstract
A mounting structure of a central rotary joint comprises the following components: a central rotary joint, a connecting board, a supporting board, a frame and bolts. The central rotary joint is fixed on the connecting board. The supporting board is fixedly arranged on the frame. The connecting board is fixed on the supporting board through the bolts. The bolts are mounted in a manner of screwing mount from bottom to top. According to the mounting structure of the central rotary joint, when the central rotary joint is replaced, the central rotary joint can be taken out from the bottom of the wheel as long as detaching the connecting board, thereby facilitating replacement, reducing maintenance cost and obtaining high applicability.
Description
Technical field
The utility model relates to the excavator technical field, specifically is a kind of mounting structure of central swivel coupling.
Background technology
Central swivel coupling and the vehicle frame junction of existing excavator, general structure normally is directly installed on central swivel coupling on the vehicle frame, has screw on the vehicle frame, and central swivel coupling is by being bolted on the vehicle frame.Though this structure stress is reliable, its limitation is arranged.In the common mounting structure, bolt is that to screw in vehicle frame from top to bottom fixing with central swivel coupling, in this case, if will be below vehicle frame dismounting central authorities swivel coupling difficulty relatively, the maintenance of central authorities' swivel coupling impacts to the later stage.
The utility model content
The purpose of this utility model is the deficiency at above-mentioned prior art existence, and a kind of mounting structure of central swivel coupling is provided, and under the prerequisite that guarantees bonding strength, guarantees the convenience of central swivel coupling dismounting and maintenance.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of mounting structure of central swivel coupling comprises central swivel coupling, junction plate, base plate, vehicle frame and bolt; Central authorities' swivel coupling is fixed on the junction plate, and base plate is fixedly mounted on the vehicle frame, and junction plate is by being bolted on the base plate.
The mounting means of described bolt is installed for screwing in from top to bottom.
Described junction plate is " X " shape.
Compared with prior art, the beneficial effect that the utility model can obtain is: vehicle frame is connected by junction plate with central swivel coupling, and the mounting means of bolt is installed convenient disassembly for screwing in from top to bottom.When changing central swivel coupling, only need the dismounting junction plate, just can be with central swivel coupling taking-up under vehicle frame, it is convenient to change, and can reduce maintenance cost, and applicability is better.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of central swivel coupling described in the utility model.
Fig. 2 is the mounting structure vertical view of central swivel coupling shown in Figure 1.
Fig. 3 is junction plate structural representation of the present utility model.
Fig. 4 is the lateral view of junction plate shown in Figure 3.
Fig. 5 is junction plate dismounting schematic diagram of the present utility model
Reference numeral is: 1, central swivel coupling, 2, junction plate, 3, base plate, 4, vehicle frame, 5, bolt.
The specific embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is described further.
As Fig. 1-shown in Figure 5, a kind of mounting structure of central swivel coupling is made up of central swivel coupling 1, junction plate 2, base plate 3, vehicle frame 4 and bolt 5.Junction plate 2 is " X " shape.
During installation, base plate 3 is weldingly fixed on the vehicle frame 4, and junction plate 2 is fixed on the base plate 3 by bolt 5, and central swivel coupling 1 is fixed on the junction plate 2 by bolt 5, and the mounting means of bolt 5 is installed for screwing in from top to bottom.Central authorities' swivel coupling 1 assembles by junction plate 2 and vehicle frame 4.
When dismantling central swivel coupling 1, under vehicle frame 4, pull down bolt 5, again junction plate 2 is rotated to suitable angle, junction plate 2 is taken out from vehicle frame 4 bottoms with central swivel coupling 1, and then central swivel coupling 1 pulled down from junction plate 2, can change central swivel coupling 1.
Claims (3)
