Abstract
A kind of full-rotating drill base device top angle cover plate, including cover board body are machined with circular through hole and square through hole on the cover board body；L-shaped notch is machined on the left side of the cover board body and rear end face, the top of each notch is inclined-plane, and the inclination angle of each inclined-plane cover board body upper surface relatively is α；The rear end face of the cover board body and the angle of left end are θ；The drop shadow curve of cover board body right side in the horizontal plane includes 2 straightways and 1 circular arc line.Size and the reasonable square hole in position are set, and the structure optimized using shape and size is designed reasonable welding groove, both facilitated to the maintenance and repair inside base device, also effectively increased the bearing capacity of base device, connecting flange.Its structure is simple, and maintainability is good, at low cost.
Description
Technical field
The utility model relates to a kind of dedicated cover board, especially a kind of upper cover suitable for full-rotating drill base device
The angle cover plate of assembly.
Background technique
The angle cover plate of cap assembly left part front and back end is the important composition part of upper cap assembly on base device, it is both complete returns
It is solid to turn the installation foundation of the positioning mounting flange of a column and the positioning of corresponding support oil cylinder cylinder bottom in drilling machine column assembly
The installation foundation for determining flange plays a significant role the entire base device bearing capacity of guarantee and stability of strutting system, while also right
Base device internal maintenance convenience has a major impact.Angle cover plate in existing full-rotating drill base device in upper cap assembly
Existing deficiency mainly has: first is that service hatch design is unreasonable, being not easy to the inside of base device into maintenance and maintenance；Second is that
Unreasonable structural design influences the carrying uniformity and bearing capacity of base device；Second is that connecting zero with interior sealed tube, side cover plate etc.
The structure at part relation position is unreasonable with size design, influences the strength and stability of entire base device；Third is that and counter-force
The design such as welding groove, structure size for pitching connecting flange association position is unreasonable, influences holding for welding quality and connecting flange
Loading capability.
Summary of the invention
Technical problem: the purpose of the utility model is to overcome the shortcoming in prior art, provide a kind of structure it is simple,
Angle cover plate easy to repair, bearing capacity is strong.
Technical solution: the full-rotating drill base device top angle cover plate of the utility model, including cover board body, the lid
Circular through hole and square through hole are machined on plate body；L-shaped lack is machined on the left side of the cover board body and rear end face
Mouthful, the top of each notch is inclined-plane, and the inclination angle of each inclined-plane cover board body upper surface relatively is α；After the cover board body
The angle of end face and left end is θ；The drop shadow curve of cover board body right side in the horizontal plane includes 2 straightways and 1 circle
Camber line.
The inclination alpha is 45 °.
The structure size of 2 L v notch vs on the cover board body is all identical.
The angle theta is greater than 90 °.
The utility model has the advantages that by adopting the above-described technical solution, the utility model setting size and position are reasonable
Square hole, the structure optimized using shape and size, is designed reasonable welding groove, both facilitated in base device
The maintenance and repair in portion also effectively increases the bearing capacity of base device, connecting flange.It solves service hatch design not conforming to
It manages, be not easy to the inside of base device into the problem of maintenance and maintenance；And it solves unreasonable structural design, influence pedestal dress
The problem of carrying uniformity and bearing capacity for setting；With being associated with the components that connect of sealed tube, side cover plate etc. in accessory into solving
The structure and size design at position are unreasonable, influence the problem of strength and stability of entire base device；It also solves and this
Part counter-force pitches welding groove, the structure size at connecting flange association position etc., and design is unreasonable, influences welding quality and connection method
The problem of bearing capacity of orchid.Its structure is simple, and maintainability is good, at low cost, has wide applicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A partial cutaway view of Fig. 1.
Specific embodiment
One embodiment of the utility model is further described with reference to the accompanying drawing:
As shown in Figure 1, a kind of dedicated full-rotating drill base device top angle cover plate, including cover board body, the lid
The circular through hole and square through hole to match with fitting dimension is machined on plate body；The left side of the cover board body and rear end face
On be machined with the L-shaped notch to match with fitting dimension, the structure size of 2 L v notch vs is all identical.The top of each notch
It is inclined-plane, the inclination angle of each inclined-plane cover board body upper surface relatively is α, as shown in Figure 2；The inclination alpha is 45 °.Institute
The angle of the rear end face and left end of stating cover board body is θ；The angle theta is greater than 90 °.Cover board body right side is in the horizontal plane
Drop shadow curve include 2 straightways and 1 circular arc line.
Claims (4)
