Therefore, an optimized and improved scheme is provided, the efficient overhaul of the mine is facilitated, and the simultaneous operation of personnel is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a multi-functional high-efficient wheel puller has solved the current problem of pulling wheel operation operating efficiency low.

The utility model adopts the technical proposal that: the multifunctional high-efficiency wheel puller comprises a nut, a screw rod is matched on the nut, reinforcing rods are fixedly connected to two sides of the nut respectively, movable pull rods are sleeved on the reinforcing rods and are L-shaped, and the two movable pull rods are opposite to each other, and horizontal sections of the lower ends of the two movable pull rods form a claw in an opposite direction.

The utility model is also characterized in that,

two reinforcing rods are horizontally and symmetrically fixed on two sides of the nut.

The upper end of the movable pull rod is provided with a through hole matched with the reinforcing rod.

The handle is welded at the upper end of the screw rod.

The reinforcing rods are welded on two sides of the nut.

The nut and the reinforcing rod are of an integrated structure.

The utility model has the advantages as follows:

the utility model discloses a high-efficient wheel puller can carry out inside and outside formula mode of colluding, is used for the working situation of hole and axle sleeve respectively.

The utility model discloses a multi-functional high-efficient wheel puller is at the mine maintenance in-process, and usable this device is dismantled any type's axle sleeve, bearing cup, end cover, miniature bearing. Especially, the bearing is convenient, fast, time-saving and labor-saving to disassemble in a mine; and the utility model discloses a multi-functional high-efficient wheel puller equipment mode can be simple, and the old and useless material of usable body side carries out simple coincidence welding manufacturing. The use method is simple, and the disassembly is convenient and quick.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses multi-functional high-efficient wheel puller, the structure is as shown in figure 1, including nut 1, the nut 1 is gone up to form and is had lead screw 4, at the both sides of nut 1 fixedly connected with reinforcing bar 2 respectively, has cup jointed movable pull rod 3 on reinforcing bar 2, and movable pull rod 3 is the L type, and two movable pull rod 3 are relative, the horizontal segment of its lower extreme forms the hook claw in opposite directions, and the hook claw can be outwards or inwards.

Two reinforcing rods 2 are horizontally and symmetrically fixed on two sides of the nut 1.

As shown in fig. 2, the upper end of the movable pull rod 3 is provided with a through hole 6 matched with the reinforcing rod 2; the thickness of the horizontal section of the movable pull rod 3 from outside to inside is gradually increased.

The upper end of the screw rod 4 is welded with a handle 5.

The reinforcing rods 2 are welded to both sides of the nut 1.

The nut 1 and the reinforcing rod 2 are of an integrated structure.

Wherein the reinforcing rod 2 and the movable pull rod 3 are both steel rods, the thickness of the reinforcing rod 2 is not less than 0.8cm, the horizontal section of the movable pull rod 3 is a thin plate, and the thickness of the thin plate is not less than 0.3cm.
