Abstract
A hook spanner includes the hand grip, the ally arm and the wrench head. The ally arm is located in front of the spanner and as the whole structure with the spanner. The wrench head is connected to the front of the ally arm by the rotating shaft and rotate in some angle by the rotating shaft. The inner wall convex of the wrench head is installed with a hook mass which is made from the high temperature alloy material. The using life of the spanner is 100 times than the present market product.
Description
(1) technical field
The present invention relates to a kind of spanner, especially relate to a kind of hook-headed wrench that is applicable to oil reservoir logging instrument loading and unloading usefulness.
(2) background technology
Hook-headed wrench is used for the loading and unloading of logging instrument, it is the important tool of using always, because logging instrument is to be operated in downhole temperature to reach 170 ℃, pressure reaches under the high-temperature and high-pressure conditions of 140Mpa, therefore, the connection place needs very firm, like this, it is stressed in use very big to be used for hook-headed wrench fastening and dismounting logging instrument connection place, needs sometimes to pound tightly with 5 pounds hammer, gib head often splits off, and influences ordinary production.
(3) summary of the invention
The object of the present invention is to provide the big and non-damageable hook-headed wrench of a kind of load.
The technical scheme that adopts is:
A kind of hook-headed wrench, comprise handle, support arm and remove head, described support arm is positioned at the front end of described spanner, and with spanner be one-time formed overall structure, the described head of removing is articulated in the front end of support arm by rotating shaft, and can do the certain angle rotation along described rotating shaft, and remove procephalic inwall and convex with a hooked scarf, it is characterized in that described hooked scarf is the hooked scarf of being made by high-temperature alloy material.
Above-mentioned high-temperature alloy material is preferably GH4169.
The present invention compared with prior art, its maximum characteristics are that the gib head of spanner has adopted high-temperature alloy material to make, and have improved service life greatly through suitable heat treatment, be more than 100 times of existing market product its service life.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
(5) specific embodiment
A kind of hook-headed wrench, comprise handle 1, support arm 2 and remove 3, support arm 2 is positioned at the front end of handle 1, and with handle 1 be one-time formed overall structure, it is shaped as arc, remove 3 and also be arc, and consistent with the support arm bending direction, its rear end is articulated in the front end of support arm 2 by rotating shaft 4, and can do the certain angle rotation along described rotating shaft 4, arc removes that solid welding has a hooked scarf 5 on 3 the inner arc wall, and hooked scarf is the hooked scarf of being made by high-temperature alloy material.
Above-mentioned high-temperature alloy material is preferably selected GH4169 for use.
Claims (2)
1, a kind of hook-headed wrench, comprise handle, support arm and remove head, described support arm is positioned at the front end of described spanner, and with spanner be one-time formed overall structure, described rear end of removing head is articulated in the front end of support arm by rotating shaft, and can do the certain angle rotation along described rotating shaft, and remove procephalic inwall and convex with a hooked scarf, it is characterized in that described hooked scarf is the hooked scarf of being made by high-temperature alloy material.
