Abstract

The utility model provides a double-hook coordinated type weighting box with outer hanging hooks for a vertical pumping unit and relates to the field of oil mechanical equipment. The double-hook coordinated type weighting box with outer hanging hooks for the vertical pumping unit comprises a weighting box body (1), a coordinated type hanging hook device (2) is arranged in the middle place of the weighting box body (1), a first outer hanging hook (3) is arranged on the upper side of the coordinated type hanging hook device (2), and a second outer hanging hook (4) is arranged on the lower side of the coordinated type hanging hook device (2). The double-hook coordinated type weighting box with outer hanging hooks for the vertical pumping unit changes a mount method of the existing single weighting, changes an inner hanging hook into an outer hanging hook, is not only easy to operate and free from loading difficult problem under a long-time outdoor bad environment condition, but also eliminates requirements of a crane. The number of operators is reduced from two to one, the maintain work of an oil well can be easily done, manpower is saved, work efficiency is improved, and maintain cost is greatly reduced.

Description

A kind of outer hanging hook of vertical oil-pumping machine, double hook linking type ballast box

Technical field:

The utility model relates to a kind of for the vertical oil-pumping machine counterweight balancing device, is specifically related to a kind of outer hanging hook, double hook linking type ballast box of vertical oil-pumping machine.

Background technique:

What the ballast box of existing vertical oil-pumping machine adopted is the inner hanging hook form, because hook is not interlock, so that the unloading difficulty, not only need crane to cooperate, also want two people to operate simultaneously, and the inner hanging hook long term exposure is under extraneous rugged environment, causes the unloading difficulty after the corrosion even can't unload.

The model utility content:

The purpose of this utility model provides a kind of outer hanging hook, double hook linking type ballast box of vertical oil-pumping machine, it can solve ballast box unloading difficulty, not easy-operating difficult problem, carry between every joint ballast box, unloading are convenient and swift, and reliable and stable, can automatically-unhookedly not cause counterweight to fall.

In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises ballast box casing 1, be provided with linking type pothook device 2 in the neutral position of ballast box casing 1, upside at linking type pothook device 2 is provided with the first outer hanging hook 3, is provided with the second outer hanging hook 4 at the downside of linking type pothook device 2.

The utility model unloads first nowel after manually control ballast box casing 1 lands, the handle that spurs again linking type pothook device 2 makes ballast box casing 1 throw off from the centre, then top box in the unloading.

The utility model has changed the carry mode between the original single-unit counterweight, make inner hanging hook into the outer hanging hook form, not only make simple to operate, can be for a long time use under extraneous rugged environment condition and do not produce the unloading hard problem, also cancelled the demand to crane, the operation number be also reduced to a people from two original people, so that the maintenance work of oil well further becomes simple, not only save manpower, improved working efficiency, and significantly reduced maintenance cost.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises ballast box casing 1, be provided with linking type pothook device 2 in the neutral position of ballast box casing 1, upside at linking type pothook device 2 is provided with the first outer hanging hook 3, is provided with the second outer hanging hook 4 at the downside of linking type pothook device 2.

This embodiment unloads first nowel after manually control ballast box casing 1 lands, the handle that spurs again linking type pothook device 2 makes ballast box casing 1 throw off from the centre, then top box in the unloading.

This embodiment has changed the carry mode between the original single-unit counterweight, make inner hanging hook into the outer hanging hook form, not only make simple to operate, can be for a long time use under extraneous rugged environment condition and do not produce the unloading hard problem, also cancelled the demand to crane, the operation number be also reduced to a people from two original people, so that the maintenance work of oil well further becomes simple, not only save manpower, improved working efficiency, and significantly reduced maintenance cost.

Claims

1. the outer hanging hook of a vertical oil-pumping machine, double hook linking type ballast box, it comprises ballast box casing (1), it is characterized in that being provided with linking type pothook device (2) in the neutral position of ballast box casing (1), upside at linking type pothook device (2) is provided with the first outer hanging hook (3), is provided with the second outer hanging hook (4) at the downside of linking type pothook device (2).
