In order to achieve the purpose, the basic scheme of the utility model provides a small crane frame for building construction, which comprises a first transverse plate and a plurality of stand columns detachably connected with the first transverse plate, wherein the stand columns are detachably connected with a second transverse plate, the lower surface of the first transverse plate is rotatably connected with a first rotating wheel and a second rotating wheel, the upper surface of the second transverse plate is provided with a rotating roller symmetrical to the second rotating wheel, and a steel cable is wound on the rotating roller;

the stand is connected with a slide bar in a sliding mode, one side, close to the first rotating wheel, of the slide bar is provided with a through hole, the slide bar is provided with a rack, the rack is meshed with a gear, the gear is coaxially connected with a motor, the motor is electrically connected with a control switch, the second transverse plate is provided with a support, the gear is rotatably installed on the support, and the steel cable sequentially penetrates through the second rotating wheel, the first rotating wheel and the through hole and is detachably connected with the bucket.

The principle and effect of this basic scheme lie in:

1. the utility model discloses a change roller, first runner and second runner and be used for hoisting the heavy object, when forward rotation changes the roller, the cable wire revolutes the roller winding, makes the cable wire end shift up gradually, and it rises to drive the well-bucket, otherwise, when the reverse rotation changes the roller, the cable wire revolutes the roller and loosens, can make the well-bucket descend to drive the rising and the decline of cable wire with the runner, the frictional force that can effectual reduction cable wire received, thereby be convenient for hoist the heavy object.

2. The utility model discloses a be equipped with the through-hole on the slide bar, the cable wire passes in the through-hole, and slide bar horizontal migration makes cable wire horizontal migration, drives the terminal heavy object horizontal migration of cable wire promptly.

3. The gear is meshed with the rack, the rack can be driven to move left and right by the rotation of the gear, and the left and right movement of the rack can be controlled by controlling the forward and reverse rotation of the gear.

4. The motor is coaxially connected with the gear, and the forward and reverse rotation of the gear can be controlled by controlling the forward and reverse rotation of the motor.

Compared with the prior art, the utility model discloses not only can reach the effect of hoisting the heavy object, but also can control the horizontal migration of heavy object through the positive and negative commentaries on classics of control motor, can make the heavy object move appointed position at the in-process of hoisting, easy operation, control is convenient.

Furthermore, an anti-separation clamping block is arranged on the sliding rod. The anti-separation clamping block can prevent the sliding rod from separating from the upright post.

Further, a third rotating wheel is rotatably connected in the through hole. The third rotating wheel can prevent the steel cable from directly contacting the inner wall of the through hole, and the friction force is reduced.

Further, the stand all passes through bolted connection with first diaphragm and second diaphragm. The bolt connection is convenient for installation and disassembly.

Further, the rotating roller is coaxially connected with a shaking hand wheel. The hand wheel is convenient to rotate the roller.

Furthermore, the free end of the steel cable is provided with a hook, and the bucket is hung on the hook. The hook is convenient for loading and unloading heavy objects.
