Abstract
The utility model discloses a bottom sealing plate of an excavator revolving platform and belongs to the technical field of engineering machines. U-shaped slotted holes (2) are formed in one side of a bottom sealing plate main body (1), round holes (3) are formed in the other side, and bolt assemblies (4) are arranged by both the U-shaped slotted holes and the round holes. Compared with the prior art, the bottom sealing plate of the excavator revolving platform has the advantages that the U-shaped slotted holes are formed on one side of the bottom sealing plate main body, installation is finished as long as the U-shaped slotted holes are inserted by the bolt assemblies (4) which are previously screwed in, the bottom sealing plate can be easily installed by only one person, and the bottom sealing plate can be easily dismounted in a converse way; and the tolerance capability of the bottom sealing plate of the revolving platform is improved, the bottom sealing plate can be more conveniently and safely assembled, repaired and disassembled, the labor intensity of workers is lowered, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of bottom sealing plate, specifically is a kind of digger revolving platform bottom sealing plate, belongs to technical field of engineering machinery.
Background technology
Excavator mainly is installed in digger revolving platform below with bottom sealing plate, is used for preventing that excavator foreign material such as silt when work from entering revolving dial inside, and the excavator component are caused damage.Bolt mounting holes on the existing excavator bottom sealing plate only has circular hole mostly, and the tolerance ability is relatively poor.For big-and-middle-sized excavator, the bottom sealing plate volume is big, Heavy Weight, and bottom sealing plate is installed in excavator turntable bottom, this causes bottom sealing plate very inconvenience when online assembling and repair demolition, often needs a people to hold up bottom sealing plate, people's installation or removal bolt, cause bottom sealing plate to install, dismantle inconvenient, labor intensive, less economical, poor stability.
The utility model content
Problem at above-mentioned prior art existence, the utility model provides a kind of digger revolving platform bottom sealing plate, improves the tolerance ability of the bottom sealing plate of revolving dial, comparatively convenient and safety all when making assembling, the repair demolition of bottom sealing plate, reduce personnel labor intensity, increase work efficiency.
To achieve these goals, the utility model offers the U-lag hole in a side of bottom sealing plate main body, and opposite side offers circular hole, and U-lag hole and circular hole are all installed by bolt assembly.
The U-lag hole is open type U-lag hole.
The beneficial effects of the utility model are: compared with prior art, this digger revolving platform bottom sealing plate, in the U-lag hole that a side of bottom sealing plate main body is offered, only need during installation the U-lag hole is inserted on the bolt assembly that is screwed in advance, one people just can easily finish the installation of bottom sealing plate, otherwise can finish the dismounting to bottom sealing plate, improved the tolerance ability of the bottom sealing plate of revolving dial, comparatively convenient and safety all when making assembling, the repair demolition of bottom sealing plate, reduce personnel labor intensity, improved operating efficiency.
Description of drawings
Fig. 1 is scheme of installation of the present utility model.
Among the figure: 1, bottom sealing plate main body, 2, the U-lag hole, 3, circular hole, 4, bolt assembly, 5 turntable holders.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, offer U-lag hole 2 in a side of bottom sealing plate main body 1, opposite side offers circular hole 3, and U-lag hole 2 and circular hole 3 are all installed by bolt assembly 4.
U-lag hole 2 is open type U-lag hole, improves the tolerance ability of the bottom sealing plate of revolving dial, and is all comparatively convenient when making assembling, the repair demolition of bottom sealing plate.
During installation, at first in the U-lag hole of bottom sealing plate main body 12 sides bolt assembly 4 just is loaded on the turntable holder 5, bolt assembly 4 just screws in turntable holder 5 and does not tighten, between bolt assembly 4 and turntable holder 5, reserve the gap that is slightly larger than bottom sealing plate main body 1 thickness, then this gap is inserted in U-lag hole 2, can regulate the position of bottom sealing plate main body 1 simultaneously, after the circular hole 3 of bottom sealing plate main body 1 opposite side and screwed hole on the turntable holder 5 are aligned, be screwed into bolt assembly 4 again, at last that the bolt assembly 4 of both sides is all fastening.
When repair demolition bottom sealing plate main body 1, earlier the bolt assembly 4 of circular hole 3 sides is pulled down, unscrew the bolt assembly 4 of U-lag hole 2 sides again, bottom sealing plate main body 1 can be extracted out at last.
Claims (2)
1. a digger revolving platform bottom sealing plate is characterized in that, offers U-lag hole (2) in a side of bottom sealing plate main body (1), and opposite side offers circular hole (3), and U-lag hole (2) and circular hole (3) are all installed by bolt assembly (4).
2. a kind of digger revolving platform bottom sealing plate according to claim 1 is characterized in that, described U-lag hole (2) is open type U-lag hole.
