Abstract
The utility model particularly relates to a steel structured pin hole repairing device for hoisting equipment, which solves the problems that the existing steel structured pin hole repairing device influences the texture stress, is time-consuming and labor-consuming, and has high cost. The steel structured pin hole repairing device for the hoisting equipment includes a process bottom plate, wherein an electromagnetic chuck is arranged on one side of the process bottom plate; electrical equipment is arranged on the other side of the electromagnetic chuck; a bore rod is connected to the output shaft of the electrical equipment; a front conical support and a rear conical support fixed with a work piece and provided with the central holes coaxial with a work piece pin hole penetrate the bore rod; and a tool apron is arranged on the bore rod. The steel structured pin hole repairing device for the hoisting equipment has reasonable and reliable structural design, is time-saving and labor-saving to repair the steel structured pin hole of the hoisting equipment, effectively improves the working efficiency, avoids the uneven stress of the work piece, further ensures the quality, and has the advantages of simple structure, convenience for operation and low cost.
Description
Technical field
The utility model relates to prosthetic device, is specially a kind of crane gear steel construction pin-and-hole prosthetic device.
Background technology
Crane gear is generally all connected with bearing pin by the steel construction unit and forms jib of all kinds, body of the tower etc., and bears multi-form alternating load.Even in the duration of insurance in longevity of crane gear, not only influential because long-term tension and compression effect makes pin-and-hole present ellipse at stress surface in various degree to connecting precision, most importantly brought potential safety hazard.
For changing the pin-and-hole joint, not only need arrive crane gear manufactory to the large-scale steel structure members roping, but also need carry out the flame cutting the pin-and-hole joint that has damaged, to some variations of steel construction piece tissue generation on every side, influence is stressed after repairing during cutting; Also having needs large lifting equipment and measuring instrument cooperating when changing, cost is high, and the time is long.
Summary of the invention
The utility model for existing crane gear steel construction pin-and-hole reparation influence its organize stressed and waste time and energy, the cost problem of higher, a kind of crane gear steel construction pin-and-hole prosthetic device is provided.
The utility model is to adopt following technical scheme to realize: crane gear steel construction pin-and-hole prosthetic device; Comprise the technology base plate; Technology base plate one side is provided with magnechuck, and the opposite side of magnechuck is provided with electrical equipment, is connected with the thorax bar on the output shaft of electrical equipment; Be installed with on the thorax bar and fix with workpiece and preceding conical bearing and back conical bearing that centre bore is coaxial with the workpiece pin-and-hole, the thorax bar is provided with tool rest.Electrical equipment is that those skilled in the art realize easily.
During use, with technology base plate fix tightly, utilize theodolite with the electrical equipment centering after, magnechuck holds the technology base plate, makes the technology base plate vertical with the workpiece pin-and-hole; Then the thorax bar is placed on the centre bore of preceding conical bearing and back conical bearing; And feed is to range; Tool setting, start electrical equipment after fastening; Slowly hand feed cutting can be accomplished the reparation of workpiece pin-and-hole, overcome the reparation of existing crane gear steel construction pin-and-hole influence its organize stressed and waste time and energy, the cost problem of higher.
The utility model reasonable in design is reliable, and is when crane gear steel construction pin-and-hole is repaired, time saving and energy saving; Effectively raise operating efficiency; And can not cause the stressed inequality of workpiece, quality further to be guaranteed, have advantage simple in structure, easy to operate and that cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-technology base plate, 2-magnechuck, 3-electrical equipment, conical bearing before the 4-thorax bar, 5-, conical bearing behind the 6-, 7-tool rest.
The specific embodiment
Crane gear steel construction pin-and-hole prosthetic device; Comprise technology base plate 1; Technology base plate 1 one sides are provided with magnechuck 2, and the opposite side of magnechuck 2 is provided with electrical equipment 3, are connected with thorax bar 4 on the output shaft of electrical equipment 3; Be installed with on the thorax bar 4 and fix with workpiece and preceding conical bearing 5 and back conical bearing 6 that centre bore is coaxial with the workpiece pin-and-hole, thorax bar 4 is provided with tool rest 7.
