Abstract
The utility model discloses a lifting hook for jack -up oil drill pipe, including the lifting hook body, the lifting hook body comprises lifting hook straight section portion and lifting hook flexion, and still including setting up the staple bolt in lifting hook straight section portion, the staple bolt still is connected with the screens board through the pivot, and the screens board is located between the both ends of lifting hook flexion, and the screens board still is connected with the connecting rod, and the one end that the screens board was kept away from to the connecting rod is connected with the balancing weight. Its simple structure, with low costs, safe and reliable utilizes lever principle to solve the problem that torque spring became invalid, eliminates the potential safety hazard, reduction in production cost.
Description
Technical field
This utility model relates to lifting field, is particularly used for the grabhook of lifting oil drill rocker.
Background technology
In petroleum machinery operation, usually need to lift by crane oil drill rocker, and can relate to using crane gear, and wherein the grabhook in equipment is for capturing oil drill rocker, in order to prevent goods from dropping, existing grabhook is equipped with spacing block board, also insurance card is become, block board is directly installed on grabhook body by rotating shaft, utilizing torque spring, one end of block board is contacted all the time with the hook end of grabhook, prevent goods from coming off, and along with the lengthening of the time of use, torque spring can lose efficacy, cause potential safety hazard, may require that with changing grabhook simultaneously, increase production cost.
Utility model content
The purpose of this utility model is to provide the grabhook for lifting oil drill rocker, utilizes lever principle to solve the problem that torque spring lost efficacy, eliminates safe hidden trouble, reduces production cost.
This utility model is achieved through the following technical solutions: for the grabhook of lifting oil drill rocker, including grabhook body, grabhook body is made up of grabhook straight section portion and grabhook bending section, also include the anchor ear being arranged on grabhook straight section portion, anchor ear is also associated with block board by rotating shaft, block board is between the two ends of grabhook bending section, and block board is also associated with connecting rod, and connecting rod has balancing weight away from one end connection of block board.
nullFor reaching above-mentioned technique effect，The principle that realizes of said structure is: this utility model utilizes increases connecting rod on block board，Then in connecting rod, increase balancing weight，Make balancing weight、Connecting rod、Block board forms an entirety，Original block board is increased weight，Utilize lever principle that block board can be automatically reset，When operation，We only need to go up shifting configuration block，Make to tilt in connecting rod，Block board is around axis of rotation，Block board is not contacted with grabhook，Thus open the opening of grabhook，After material is hung over grabhook bending section，No longer hold up balancing weight，Now configuration block downward freely falling body under gravity moves，Thus drive and rotate under connecting rod，Block board then can rotate around the axis and be returned to home position，Make the ends contact of block board and grabhook bending section，Thus close grabhook opening，Reach the effect of insurance，And the acquisition structure of this structure only only has rotating shaft，The service life of rotating shaft is the longest，Original torque spring that block board can be resetted can be cancelled，Increase the service life of grabhook，Ground connection production cost.
Preferably, the angle between described connecting rod and block board is more than or equal to 90 degree.
Preferably, the quantity of described connecting rod is 2, and 2 connecting rods are both connected on block board, and grabhook bending section is arranged between 2 connecting rods.
Preferably, described balancing weight is the iron block of arbitrary shape or lead or ceramic block.
Preferably, rotating shaft is also arranged with torque spring.
This utility model compared with prior art, has such advantages as and beneficial effect: simple in construction, low cost, safe and reliable, utilizes lever principle to solve the problem that torque spring lost efficacy, eliminates safe hidden trouble, reduces production cost.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, exemplary embodiment of the present utility model and explanation thereof are only used for explaining this utility model, are not intended as restriction of the present utility model.
Embodiment 1:
Grabhook for lifting oil drill rocker, including grabhook body, grabhook body is made up of grabhook straight section portion 1 and grabhook bending section 2, also include the anchor ear 3 being arranged on grabhook straight section portion 1, anchor ear 3 is also associated with block board 5 by rotating shaft 4, block board 5 is between the two ends of grabhook bending section 2, and block board 5 is also associated with connecting rod 6, and connecting rod has balancing weight 7 away from one end connection of block board.
nullFor reaching above-mentioned technique effect，The principle that realizes of said structure is: this utility model utilizes increases connecting rod 6 on block board 5，Then in connecting rod, increase balancing weight 7，Make balancing weight 7、Connecting rod、Block board forms an entirety，Original block board is increased weight，Utilize lever principle that block board can be automatically reset，When operation，We only need to go up shifting configuration block，Make to tilt in connecting rod，Block board is around axis of rotation，Block board is not contacted with grabhook，Thus open the opening of grabhook，After material is hung over grabhook bending section，No longer hold up balancing weight，Now configuration block downward freely falling body under gravity moves，Thus drive and rotate under connecting rod，Block board then can rotate around the axis and be returned to home position，Make the ends contact of block board and grabhook bending section，Thus close grabhook opening，Reach the effect of insurance，And the acquisition structure of this structure only only has rotating shaft，The service life of rotating shaft is the longest，Original torque spring that block board can be resetted can be cancelled，Increase the service life of grabhook，Ground connection production cost.
Preferably, the angle between described connecting rod and block board 5 is more than or equal to 90 degree.
Preferably, the quantity of described connecting rod is 2, and 2 connecting rods are both connected on block board 5, and grabhook bending section 2 is arranged between 2 connecting rods.
Preferably, described balancing weight 7 is the iron block of arbitrary shape or lead or ceramic block.
Preferably, rotating shaft is also arranged with torque spring.
This utility model compared with prior art, has such advantages as and beneficial effect: simple in construction, low cost, safe and reliable, utilizes lever principle to solve the problem that torque spring lost efficacy, eliminates safe hidden trouble, reduces production cost.
Above-described detailed description of the invention; the purpose of this utility model, technical scheme and beneficial effect are further described; it is it should be understood that; the foregoing is only detailed description of the invention of the present utility model; it is not used to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, within should be included in protection domain of the present utility model.
