Problems solved by technology

Since the components on the thruster are installed on a U-shaped aluminum alloy frame, its structure is very compact. In order to reduce the risk of interference, ordinary nuts can only be installed on the outside of the aluminum alloy frame. Due to the long bolts, it is necessary to install the drilling rig before the oil cylinder It is necessary to complete the fixing work of all the parts on the outside of the aluminum alloy frame, and when replacing the outside parts, the drilling rig propulsion cylinder must be removed, and the workload is very heavy

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as Figures 1 to 3 As shown, a mosaic nut for a propeller of a rock drilling rig includes a U-shaped aluminum alloy beam 1 and an oil pipe support 2; it also includes an inlay nut 3 and a bolt 4, wherein the oil pipe support 2 passes and bolts 4 are fixed on the U-shaped aluminum alloy beam 1; the inlaid nut 3 is installed inside the U-shaped aluminum alloy frame 1, and the inlaid nut 3 includes a flat part 301 and a protruding part 302.

[0017] As a further improvement of the present invention, the axial through hole of the embedded nut 3 is processed with a right-handed internal thread.

[0018] As a further improvement of the present invention, in the embedded nut 3, the protruding portion 302 is processed with a left-handed external thread.

[0019] As a further improvement of the present invention, the U-shaped aluminum alloy beam 1 is provided with...

Abstract

The invention provides an embedment type nut used for a drilling jumbo propeller. The embedment type nut comprises a U-shaped aluminum alloy beam and an oil pipe support, and further comprises embedment type nut bodies and bolts. The oil pipe support is fixed to the U-shaped aluminum alloy beam through the embedment type nut bodies and the bolts. The embedment type nut bodies are installed on the inner side of the U-shaped aluminum alloy frame. Each embedment type nut body comprises a flat part and a protruding part. Compared with the prior art, the embedment type nut bodies are installed on the inner side of the U-shaped aluminum alloy frame, the installation direction of the bolts is changed, and therefore parts needing to be fixed are made independent. Compared with installation achieved through ordinary nuts, the distance by which the embedment type nut bodies protrude from the inner surface of the U-shaped aluminum alloy beam is short, and the risk of interference with oil cylinders and other movement parts is effectively lowered. The embedment type nut is simple in structure and convenient to install and maintain.

Description

technical field [0001] The invention relates to an inlaid nut, in particular to an inlaid nut for a propeller of a rock drilling jumbo, and belongs to the technical field of the rock drilling jumbo. Background technique [0002] The rock drilling jumbo is a kind of rock drilling equipment that adopts the drilling and blasting method for tunnel and underground engineering. It can move and support multiple rock drilling machines to perform drilling operations at the same time. At present, the various parts on the thruster of the rock drilling jumbo are fixed by common bolts and nuts. Since the components on the thruster are installed on a U-shaped aluminum alloy frame, its structure is very compact. In order to reduce the risk of interference, ordinary nuts can only be installed on the outside of the aluminum alloy frame. Due to the long bolts, it is necessary to install the drilling rig before the oil cylinder The fixing work of all the components outside the aluminum alloy ...
