Abstract
The invention relates to a large-diameter high-temperature bolt dismounting tool. The large-diameter high-temperature bolt dismounting tool comprises an upper cover plate, a lower cover plate, pin rollers and a shell. The upper cover plate and the lower cover plate are mounted on the two sides of the shell respectively. The two ends of each pin roller are mounted in a sliding groove of the upper cover plate and a sliding groove of the lower cover plate respectively, and the middle parts of the pin rollers slide in grooves which are gradually lengthened in the radial depth direction of the shell. Compared with the prior part, the large-diameter high-temperature bolt dismounting tool has the advantages of being capable of protecting spare parts, convenient to maintain, safe, reliable and the like.
Description
Technical field
The present invention relates to a kind of extracting tool, especially relate to a kind of major diameter high temperature bolt extracting tool.
Background technology
Bolt plays vital effect in the safe operation of power plant.In the impact based on the factor such as longtime running and on-the-spot hot environment, often there is the situation that bolt cannot be dismantled.Particularly visual plant, because operating condition, safety requirements are high, often adopts dark blind hole studding bolt of serration.These bolt general diameters are large, threaded engagement length is long, may produce the thread Pilot hole be positioned on apparatus body in unloading process and destroy, in addition the restriction of each side such as material, heat treatment, on-the-spot processing conditions is subject to, the process more complicated of thread Pilot hole and difficulty, this, by directly affecting the service work of power plant, causes heavy economic losses.Pipe vice is adopted to pull original methods such as adding sledgehammer, hand hammer beats by inquiry at present, even if pipe vice skids, fracture causes unsafe conditions because tight power often causes comparatively greatly. the bolt pulled down also has bitten more severe.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of major diameter high temperature bolt extracting tool is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of major diameter high temperature bolt extracting tool, it is characterized in that, comprise upper cover plate, lower cover, roller and housing, described upper and lower cover plate is arranged on housing both sides respectively, described roller two ends are arranged in the sliding tray of upper cover plate and lower cover respectively, and described roller mid portion slides in the groove that the radial depth of housing is elongated gradually.
Described upper and lower cover plate central has circular hole, is evenly distributed with the curved channel slided for roller end outside circular hole.
Described roller has 3, and there is convex body at each roller two ends, and is interspersed in respectively in 3 curved channels of upper and lower cover plate.
Groove in described housing is provided with 3, is slidably connected with each roller.
The radial depth of each groove is elongated gradually in the counterclockwise direction.
Compared with prior art, the present invention has the following advantages:
1) spare part is protected: prevent in demounting bolt process, bolt surface is damaged;
2) maintenance is convenient: use this extracting tool, make its Bolt dismantling, install time saving and energy saving, more science and convenient;
3) safe and reliable: for large diameter bolt, comparatively large owing to dismantling required moment, easily because pipe wrench fracture injures staff or causes the generation of device damage accident.This instrument bolt and Tool Room self-locking is used to there is not skidding safe and reliable.
Accompanying drawing explanation
Fig. 1 is decomposition texture schematic diagram of the present invention;
Fig. 2 is the structural representation after the present invention assembles.
Wherein 1 is upper cover plate, and 2 is housing, and 3 is ball, and 4 is lower cover.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment
As shown in Figure 1, a kind of major diameter high temperature bolt extracting tool, comprise upper cover plate 1, lower cover 4, roller 3 and housing 2, described upper cover plate 1, lower cover 4 are arranged on housing 2 both sides respectively, described roller 3 two ends are arranged in the sliding tray of upper cover plate 1 and lower cover 4 respectively, and described roller 3 mid portion slides in the groove that the radial depth of housing is elongated gradually.
Described upper cover plate 1, lower cover 4 center have circular hole, are evenly distributed with the curved channel slided for roller end outside circular hole.Described roller 3 has 3, and there is convex body at each roller two ends, and is interspersed in respectively in 3 curved channels of upper cover plate 1, lower cover 4.Groove in described housing 2 is provided with 3, is slidably connected with each roller 3.The radial depth of each groove is elongated gradually in the counterclockwise direction.
Counterclockwise rotate, roller and body of tool circular arc locking face and bolt light rod part form stable self-locking; Rotate clockwise: the self-locking removing roller and body of tool circular arc locking face and bolt light rod part.
