Abstract
The invention relates to a spanner suitable for a fixed nut at the end tip of a metal roller. The spanner comprises a semicircle lantern ring and a semicircle metal sheet symmetrically arranged with the lantern ring; movable tooth blocks are arranged on the semicircle lantern ring, the same ends of the lantern ring and the metal sheet are pivoted with each other, and a locking device is arranged between the other end of the metal sheet and the corresponding end of the lantern ring. The locking device can consist of a bolt fixedly arranged on the lantern ring and a buckle piece hinged on the metal sheet. Furthermore, the axial thicknesses of the metal sheet and the lantern are the same. The fixed nut can be conveniently clamped in the operation. Furthermore, the radial thickness of the metal sheet is 2mm. According to the spanner provided by the invention, the semicircle lantern ring and the semicircle metal sheet are locked and combined to fix and dismount the fixed nut at the end tip of the metal roller, as the metal sheet is quite light, the weight of the spanner is greatly reduced and is basically the same with that of the existing crescent spanner, and the work of an operator is facilitated.
Description
Technical field
The present invention relates to be used to tighten or loosen the spanner of metallic roll termination hold-down nut, particularly, this spanner acts on diameter is offered notch greater than Φ 300mm and cylindrical nut.
Background technology
At present; When the nut of working roll, backing roll or similar roller class end of dismounting or adjustment milling train, often adopt the spanner of crescent (i.e. semicircle), for the less clamp nut of diameter; The weight of spanner generally is no more than 2kg, and the operating personnel uses more convenient; And because the diameter great majority of the hold-down nut of metallic roll are all very big, reach more than the Φ 600mm such as the termination hold-down nut diameter of the working roll of large-sized rolling mills, semicircular opening spanner weight is bigger; Weight has 6Kg approximately, and along with the increase of hold-down nut diameter, corresponding semicircular opening spanner weight is also increasing; The weight of major diameter size knuckle buster can reach 7～8kg, and operation is inconvenience very, needs two operating personnel; Buttress another one people's operation by a people.Because the oral area of semicircular opening spanner can only combine with the hemicycle side face of set bolt when operation, if misoperation will fall down, injury accident takes place.
To above-mentioned situation; The applicant has applied for that on December 2nd, 2011 name is called the patent of invention (application number: 201110397647.9) of " fastener that is used for metallic roll termination hold-down nut "; But this patent has been realized the location of hold-down nut and fastening through the movable tooth piece of the collar and one-directional rotation; Avoid spanner to drop and caused industrial injury, improved operating efficiency.But because this device increased circle half than existing crescent wrenches, thereby weight increases greatly, at least than former knuckle buster increase by 40%.Such as, acting on the knuckle buster that diameter is the hold-down nut of Φ 600mm, weight is 6kg, after the technical scheme of employing foregoing invention, its weight reaches 11kg.Because of weight increases, brought operational inconvenience for the operation worker, such as with its suit or when taking off on hold-down nut, have certain degree of difficulty.
Summary of the invention
Technical problem to be solved by this invention is a kind of spanner that is applicable to the hold-down nut of metallic roll termination, and it is in light weight, and easy to operate.
The technical scheme that the present invention addresses the above problem is following:
A kind of spanner that is applicable to the hold-down nut of metallic roll termination is characterized in that:
Comprise the semicircle collar and with the symmetrically arranged semicircle sheet metal of the collar, the said semicircle collar is provided with movable tooth piece, the same end of the said collar and sheet metal is articulated, and is provided with locking device between an other end of sheet metal and the corresponding end of the collar.
As preferred version, said locking device is made up of with the hasp sheet that is hinged on the sheet metal the bolt that sets firmly on the collar.The hasp sheet is buckled on the bolt, and the two is closely linked.
Further, said sheet metal equates with the axial width of the collar.When operation, be convenient to accurate screens with hold-down nut.
Further, the radial thickness of said sheet metal is 2mm.
The present invention is locked through the semicircle collar and semicircle sheet metal; Realize fixing or dismounting to metallic roll termination hold-down nut; Because of the sheet metal very light in weight; Spanner weight of the present invention is alleviated greatly, and the weight basically identical of its weight and existing crescent wrenches has made things convenient for operative employee's work; In addition, because the cost of sheet metal and locking device is all very low, so cost of manufacture of the present invention is low.In a word, the present invention has avoided the unsafe factor of existing knuckle buster because of dropping easily and existing, and have own wt light in the operation advantage, utilization is worthy to be popularized very much.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the sketch map under sheet metal of the present invention and the collar locking state.
Fig. 3 is the structural representation of locking device among the present invention.
Among the figure: 1, the collar; 2, sheet metal; 3, locking device; 31, bolt; 32, hasp sheet 4, handle; 5, movable tooth piece.
The specific embodiment
See also Fig. 1 and Fig. 2; A kind of spanner that is applicable to the hold-down nut of metallic roll termination, comprise the semicircle collar 1 and with the collar 1 symmetrically arranged semicircle sheet metal 2, it is a circle that these two semicircles combine; Be installed with handle 4 and movable tooth piece 5 on the said semicircle collar; The structure of movable tooth piece 5 sees that application number is 201110397647.9 patent of invention, and rectangular block architecture is in full accord in handle 4 and the above-mentioned patent, and this patent is no longer narrated.The same end of the said collar and sheet metal is articulated, and is provided with locking device 3 between an other end 21 of sheet metal and the corresponding end 11 of the collar.
As shown in Figure 3, said locking device 3 is made up of with the hasp sheet 32 that is hinged on the sheet metal the bolt 31 that sets firmly on the collar.Under closure state, the hasp sheet is buckled on the bolt, and the two is closely linked.Can find out also that from Fig. 2 sheet metal 2 equates with the axial width of the collar 1.According to actual needs, the radial thickness of said sheet metal 2 is 2mm.
Utilizing the present invention to carry out fastening or during the fixed disassembly nut; Earlier the semicircle collar 1 is sleeved on the periphery of hold-down nut; Rotate sheet metal 2 then, the two closure is a circle, and the periphery of hold-down nut is wrapped; Then the hasp sheet is pressed on the bolt, with the collar and sheet metal locking.As shown in Figure 4; Spanner of the present invention is enclosed within on the hold-down nut of metallic roll termination, rotates this fastener, a movable tooth piece is sticked in the notch of hold-down nut; Knock the handle on the collar with tup; Give the collar power of counterclockwise rotating, just can force nut to turn clockwise, reach the purpose of loosening hold-down nut through the collar; During clamp nut, the collar is turned over if desired, be enclosed within on the nut, knock the handle of the collar, apply the power that clockwise rotates, just can force nut to turn clockwise, play the effect of reinforcing through the collar to it with the other one side of the collar.
