The existing pile foundation reamer adopts a rotary drilling machine to enlarge the bottom, but the rotary drilling machine is continuously operated in the construction process, the equipment is not provided with a centering device, the center position can be adjusted only by naked eyes, the rotary drilling machine is in suspended work in construction, no supporting point is used for stabilizing, and the error is larger and larger, so that the center point of the bottom of the pile foundation, which is dug by the rotary drilling machine, is inaccurate, the error is larger, the precision is not enough, the specification of the bottom of each pile foundation is not uniform, the cost is high, and the construction is difficult. The present utility model therefore proposes a self-centering electric stay device.
Disclosure of Invention
The utility model overcomes the defects existing in the prior art and provides a self-centering electric stay bar device.
In order to solve the technical problems, the utility model adopts the following technical scheme: a self-centering motorized strut device, comprising:
a column;
the method is characterized in that: the novel structure is characterized in that three push rod sleeves are arranged on the outer wall of the top end of the upright post, push rods are arranged in the push rod sleeves, push rod support plates are arranged at the outer ends of the push rods, screw nuts are fixedly arranged at the inner ends of the push rods, screw rods which are connected with the screw nuts through threads are arranged in the screw nuts, a fixing seat is fixedly arranged at the inner ends of the screw rods, a speed reducer is connected with the fixing seat through a coupling, a motor connected with the speed reducer is arranged on one side of the speed reducer, and the speed reducer is fixedly arranged on the inner wall of the push rod sleeve.
In the structure, the included angle between two adjacent push rod sleeves is 120 degrees.
In the structure, the outer end surfaces of the push rod supporting plates are provided with the positioning needles.
In the structure, the outer wall of the inner end of the push rod sleeve is provided with notches which are matched with the motor.
In the structure, a plurality of lighting lamp brackets are arranged on the bottom end surface of the push rod sleeve.
Compared with the prior art, the utility model has the beneficial effects that: the self-centering electric stay bar device is reasonable in structural design, three push rods controlled by the motors are arranged around the upright post, the motors drive the screw rods to rotate through the speed reducers, the screw rods and the screw rod nuts are matched to realize the extension and retraction of the push rods, the operation is simple, the vertical precision of the upright post can be ensured, and the construction is convenient.

FIG. 1 is a schematic view of a self-centering motorized strut apparatus according to an embodiment of the present utility model;
fig. 2 is a schematic diagram of a connection structure between a motor and a push rod in a self-centering electric brace apparatus according to an embodiment of the present utility model.
In the figure:
1. a column; 2. a push rod sleeve; 3. a push rod; 4. a push rod support plate; 5. a lead screw nut; 6. a screw rod; 7. a fixing seat; 8. a coupling; 9. a speed reducer; 10. a motor; 11. a positioning needle; 12. and (5) a notch.
Description of the embodiments
The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.
As shown in fig. 1-2, a self-centering motorized strut device comprising:
a column 1;
the method is characterized in that: the novel vertical column structure is characterized in that three push rod sleeves 2 are arranged on the outer wall of the top end of the vertical column 1, push rods 3 are arranged in the push rod sleeves 2, push rod support plates 4 are arranged at the outer ends of the push rods 3, screw nuts 5 are fixedly arranged at the inner ends of the push rods 3, screw rods 6 which are connected with the screw nuts through threads are arranged in the screw nuts 5, fixing seats 7 are fixedly arranged at the inner ends of the screw rods 6, the fixing seats 7 are connected with speed reducers 9 through couplings 8, motors 10 connected with the speed reducers 9 are arranged on one sides of the speed reducers 9, and the speed reducers 9 are fixedly arranged on the inner walls of the push rod sleeves 2.
In the above structure, the included angle between two adjacent push rod sleeves 2 is 120 degrees.
In the structure, the outer end surfaces of the push rod supporting plates 4 are provided with positioning needles 11.
