Abstract
The utility model relates to a large-scale thread ring dismounting equipment which comprises a connection rod, a support rack and an extended rod. The connection rod is connected with the support rack via a perforated flange, and a support rod is uniformly provided with four reinforcing plates which are all provided with front spanners; the support rack is connected with the extended rod via a bolt, the center of the extended rod is provided with a lifting lug, a plurality of balance weights are arranged round the right end of the extended rod, the rear end of the extended rod is provided with two through holes perpendicular to each other near the lifting lug, and each through hole is internally provided with a rear spanner. The large-scale thread ring dismounting equipment has the beneficial effects that the employment of the front and the rear spanners realizes amplification of force moment, thereby avoiding thread damage caused by forced screwing, and the employment of the weights can adjust the concentricity of thread axis and central axis of tool in order to avoid seizing between inner and outer threads and abandonment of work pieces caused by increase of mutual bias torque moment of axes.
Description
Technical field
The utility model relates to the dismantling device of industries such as oil, chemical industry, electric power and machinery with screw thread, relates in particular to a kind of large-scale threaded collar attaching/detaching apparatus.
Background technology
In the main equipment maintenance, the dismounting of its screw or installation, mainly be to use electronic or pneumatic impact wrench at present, use these instruments to need electricity consumption, and some equipment be far away from power supply, it is inconvenient to connect electricity, especially use electronic or also there is unsafe factor in pneumatic impact wrench, as breaking electric wire easily or owing to misoperation injures the person and use cost is also very high, non-moment amplifies kinetic energy simultaneously, the artificial difficulty of rotating comes the application of force to be difficult to control with crane gear; Can't carry out the concentricity levelling, center of gravity can't be regulated; Easily cause screw thread to kill mutually and scrap workpiece.
The utility model content
The purpose of this utility model provides a kind of large-scale threaded collar attaching/detaching apparatus, amplifies kinetic energy to overcome the existing equipment attaching/detaching apparatus non-moment that is threaded, and the artificial difficulty of rotating comes the application of force to be difficult to control with crane gear; Can't carry out the concentricity levelling, center of gravity can't be regulated; Easily cause screw thread to kill mutually and scrap workpiece, the deficiency that use cost is high.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of large-scale threaded collar attaching/detaching apparatus comprises connecting plate, bracing frame and extension bar, and the side of described connecting plate is provided with boss, and connecting rod is connected with bracing frame by ring flange with holes; Be evenly distributed with four gussets on the described support bar, four gussets are all vertical with ring flange with holes, be equipped with preceding spanner on four gussets, spanner is by being bolted on the gusset, the middle part of support frame as described above is provided with bearing inner sleeve, bearing inner sleeve is provided with bearing, and the outside of bearing is covered with bearing outside, and the side of bearing outside is provided with hanger; Support frame as described above is connected with extension bar by bolt, the middle part of extension bar is provided with hanger, the right-hand member of extension bar is provided with graduation mark, the right-hand member outside of extension bar is provided with some equilibrate counterweights, the left side of equilibrate counterweight is provided with preceding snap ring, the right side of equilibrate counterweight is provided with the back snap ring, described two snap rings include the steel plate of semicircular arc, the circular arc internal diameter of steel plate matches with extension bar, described two steel plates connect by bolt, the end of described extension bar is provided with and draws ear, and the end of extension bar is equipped with the back spanner near drawing the ear place to be provided with orthogonal two through holes in described two through holes.
The beneficial effects of the utility model are: realized the moment amplification with the front and back spanner, easily artificial the rotation with sensation controllable force square size, can prevent to screw by force and cause the damage screw thread during application of force; The concentricity that can carry out the axis of thread and tool device central axis under the adjusting of counterweight is aligned, and when preventing that axis from having the deviation moment of torsion to increase to screw mutually, causes internal and external threads to kill and the workpiece subscription rate mutually; Can carry out center of gravity and reconcile, can together steadily take off together with screwing out part using of crane gear at held stationary when packing into separately.
