Abstract

Disclosed is a jacking bracket, which relates to a jack assistant tool. A base is disposed under a support, reverse cogs are arranged on the lower portion of the base to form an antiskid base, a supporting plate is mounted at the top of the support, the supporting plate is connected with the support by employing a rotary shaft, one end of the supporting plate is equipped with a position adjusting screw, and a locking groove for placing a jacking base is arranged on the supporting plate. Users can place a jack on the supporting plate and regulate the position adjusting screw to control reasonable positions of the jack. The utility model is characterized in that the rotary shaft of the support is capable of rotating automatically and performing the function of adjusting angles, and the position adjusting screw enables the jack to always keep staying at the center of the supporting plate, thereby enabling the jack to bear balanced stress. Besides, the reverse cogs under the base can enlarge friction between a supporting seat and the ground, thereby performing antiskid function. Moreover, the jack is enabled to automatically adjust angles when the angles shift in the process of using the jack, thereby always keeping stress points on the ground and avoiding the unsafe factors that the jack is easy to be broken when used slantingly, the jack pops out to hurt people because of unreasonable design of the stress points, and the like.

Description

Jacking bracket

Technical field

The utility model belongs to oil field equipment, relates to a kind of jack appurtenance.

Background technology

Because oil pumper when mounted, there are error in oil pumper and well head, and be on-the-spot to the oil pumper adjustment, mostly adopt the jack adjustment, jack need tilt use, and stress point is at the center during very heavy design, tilt to use and often damage jack, very heavy can the ejection hurted sb.'s feelings poor safety performance when serious.

Summary of the invention

At the deficiencies in the prior art, but the purpose of this utility model provides a kind of jacking bracket of automatically regulating angle, and is unreasonable to solve the very heavy stress point design of prior art, tilts to use fragile jack, very heavy can the ejection hurted sb.'s feelings problems such as poor safety performance when serious.

The technical scheme that its technical matters that solves the utility model adopts provides a self-adjustable jacking bracket, this jacking bracket is made up of base, stay bearing plate, rotating shaft, positioning screw, support, base is arranged on the below of support, the base bottom is provided with reverse teeth, constitutes anti-skidding base; Prop up top of the trellis stay bearing plate is set, stay bearing plate adopts rotating shaft to be connected with support, and stay bearing plate one end is provided with the positioning screw, the draw-in groove of putting jack base is set above the stay bearing plate, jack is placed on the stay bearing plate in the draw-in groove, by regulating the positioning screw, the rational position of control jack.

Adopting good effect of the present utility model is when jack is worked, the bearing rotating shaft can be rotated voluntarily, play the effect of adjusting angle, the positioning screw allows the very heavy stay bearing plate center that remains at, make the jack stress equalization, make very heavyly in use when angle is subjected to displacement, adjusting angle remains stress point on ground voluntarily.Reverse teeth below the base can increase bearing and ground-surface friction force, play skidproof effect.It is fragile to have solved jack inclination use, and stress point designs unreasonable ejection and hurts sb.'s feelings, problems such as poor safety performance.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model birds-eye vieies;

1 base, 2 reverse teeth, 3 stay bearing plates, 4 rotating shafts, 5 jacks, 6 positioning screws, 7 supports, 8 center-point signs among the figure.

The specific embodiment

As shown in the figure; This jacking bracket is made up of base (1), stay bearing plate (3), rotating shaft (4), positioning screw (6), support (7), and base (1) is arranged on the below of support (7), and base (1) bottom is provided with reverse teeth (2), constitutes anti-skidding base; Prop up top of the trellis stay bearing plate (3) is set, stay bearing plate (3) adopts rotating shaft (4) to flexibly connect with support (7), stay bearing plate (3) one ends are provided with positioning screw (6), the center-point sign (8) of putting jack base is set above the stay bearing plate (3), placing stay bearing plate (3) to go up center-point sign (8) jack (5) locates, by regulating positioning screw (6), make the center of jack (5) on stay bearing plate, very heavy stress point is remained at center-point, make jack be in the state of having an effect an of the best all the time.

Claims (3)

1, a kind of jacking bracket mainly is made up of base, stay bearing plate, support, it is characterized in that base is arranged on the below of support; Prop up top of the trellis stay bearing plate is set, stay bearing plate one end is provided with the positioning screw, and the draw-in groove of putting jack base is set above the stay bearing plate, jack is placed on the stay bearing plate, by regulating the positioning screw, the rational position of control jack.

2,, it is characterized in that the base bottom is provided with reverse teeth, constitutes anti-skidding base according to the described jacking bracket of claim 1.

3,, it is characterized in that stay bearing plate and support adopt rotating shaft to be connected according to the described jacking bracket of claim 1.
