Description

[Technical field]

[0001] The utility model relates to the technical field of electric hoists, in particular to a hanging electric hoist. [Background technology]

[0002] The suspended electric hoist is a type of electric hoist. It has a hook on the top and can be hung on a steel beam. Unlike other electric hoists, it can only be fixed and not travel. It cannot be equipped with a monorail trolley, so it cannot travel left and right on the I-beam. The structure of the suspended electric hoist is relatively simple. It mainly welds one of the hooks on the shell, and the shell is hung on the I-beam by the hook to fix the shell. When actually lifting an object, another movable hook is used to hook the object, and the motor output shaft is used to drive the winding roller to rotate, so that the winding roller reels the steel wire, and the reeling of the steel wire causes the hook to hook the object, thereby realizing the lifting of the object.

[0003] Although the above technical solution can realize the hook to hook the object, there are still the following problems:

[0004] 1. First of all, during the winding process, the steel wire is mainly wound by the motor-driven winding roller. When the steel wire is wound, if the steel wire is not arranged, it is easy to cause the steel wire to be wound in one place. Once the steel wire is wound in one place, the weight of the winding at that place will increase. Once the weight of the winding at that place is longer than that of a place without steel wire on both sides or one side, it will easily cause the winding place to be damaged or bent.

[0005] 2. During regular use, steel wire generally needs to be oiled to prevent rust. In order to oil the steel wire, oil is usually applied to the steel wire with a brush during winding, or the steel wire is passed through an oil storage tank opened on the inner wall of the shell to oil the steel wire. Oiling with a manual brush will greatly increase the labor of personnel, and passing the steel wire through the oil tank for oiling will easily cause part of the oil in the oil tank to be pulled out of the oil tank by the steel wire, resulting in excessive oil on the steel wire. As a result, when the steel wire is subsequently hoisted, excess oil drips on the ground or falls to the outside with the steel wire, which indirectly causes a great waste of oil in the oil tank. [Contents of the utility model]

[0006] The purpose of the utility model is to solve the problems in the prior art and to provide a suspended electric hoist which can sort and reel steel wires and can also oil the steel wires.

[0017] Preferably, the movable seat is fixedly connected with limiting blocks which are arranged opposite to each other, and the limiting blocks are located on both sides of the first roller and the second roller.

[0018] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model utilizes the sliding grooves provided on the roller one and the roller two to limit the steel wire in the roller one and the roller two, and the reciprocating movement of the movable seat can make the steel wire move with the movement of the movable seat, so as to achieve the arrangement of the steel wire, and utilizes the contact between the ball and the steel wire, and the friction between the steel wire and the ball can make the ball rotate on the oiling roller, and utilizes the rotation of the ball each time, the ball obtains the oil in the chamber and smears it on the steel wire, so as to achieve the oiling of the steel wire, and by oiling the steel wire and sorting the steel wire, it can reduce the situation that the steel wire is wound in one place, and then reduce the bending and damage of the steel wire, and at the same time, by oiling the steel wire, it can also reduce the situation that the excess oil drips due to the steel wire passing through the storage oil tank.

The winding mechanism 3 in the utility model is mainly used to wind up the steel wire 4, and is mainly composed of a winding roller 23, a motor 3 24 and a reducer 25. The motor 3 24 is fixedly connected to the shell 2, and the reducer 25 is fixedly connected to the shell 2, and the output shaft of the motor 3 24 is connected to the reducer 25 to achieve a deceleration effect. The rotation of the output shaft of the motor 3 24 can drive the winding roller 23 fixedly connected to the output shaft of the motor 3 24 to rotate, so as to achieve the winding of the steel wire 4 by the winding roller 23. Through the winding of the steel wire 4, the steel wire 4 drives the hook 5 to lift the object;

[0030] The hanging electric hoist in the utility model further comprises: a moving seat 6, a roller 1 8 and a roller 2 9;

[0031] The movable seat 6 is driven to be horizontally placed and slidably connected to the outer shell 2 along the winding mechanism 3. The steel wire 4 is passed through the roller 1 8 and the roller 2 9 which are rotatably connected to the movable seat 6, and the sliding groove 10 provided on the roller 1 8 and the roller 2 9 is used to position the steel wire 4, thereby realizing the positioning of the steel wire 4. The movement of the movable seat 6 is utilized to arrange the steel wire 4 during the winding process of the winding roller 23.

[0032] Specifically, an oiling roller 11 connected to a built-in chamber is driven to slide relatively on the movable seat 6, the steel wire 4 is arranged on the oiling roller 11, and the side wall of the steel wire 4 is rotatably connected to the oiling roller 11, and a ball 12 at one end of which is located in the chamber is in contact with the steel wire 4. When the steel wire 4 is wound, the steel wire 4 will drive the ball 12 to rotate. Once the ball 12 rotates, the ball 12 will drive the oil in the chamber to enter the steel wire 4, thereby achieving oiling of the steel wire 4, and an oil delivery mechanism 13 is arranged on the outer shell 2. The oil delivery mechanism 13 is connected to the chamber through a pipeline, so that the oil delivery mechanism 13 can transport oil into the chamber to replenish the oil in the chamber.

[0033] Specifically, a motor 15 is fixedly connected to the movable seat 6, and the output shaft of the motor 15 is fixedly connected to the bidirectional lead screw rotatably connected to the movable seat 6, so that the bidirectional lead screw 14 can drive the movable block 16 threadedly connected to it and slidably connected to the movable seat 6 to move, so that the movable block 16 drives the oil coating roller 11 fixedly connected to the movable block 16 to move, thereby achieving the contact between the oil coating roller 11 and the steel wire 4.

[0034] Specifically, since the oil delivery mechanism 13 includes a storage box 17 and a small transmission pump 18, the storage box 17 is fixedly connected to the outer shell 2, and the small transmission pump 18 is fixedly connected in the storage box 17, one end of the small transmission pump 18 is connected to the chamber through a pipeline, and the oil is transmitted by the small transmission pump 18 through the pipeline into the chamber, thereby realizing the replenishment of oil in the chamber.

[0035] Specifically, the motor 20 is fixedly connected to the housing 2, and the output shaft of the motor 20 is fixedly connected to the screw 2 19 rotatably connected to the housing 2.

[0037] Specifically, the limit blocks 22 are fixedly connected to the movable seat 6 and are arranged on both sides of the roller 1 8 and the roller 2 9, so as to limit the position of the steel wire 4 and reduce the situation where the steel wire 4 escapes from the limit blocks 22.

[0038] Principle of the utility model: when the steel wire 4 enters the winding mechanism 3 for winding, the roller 1 8 and the roller 2 9 are used to limit the steel wire 4 on the movable seat 6, and the movable seat 6 moves back and forth to arrange the steel wire 4 during the winding process. When the steel wire 4 is wound, the steel wire 4 will stick to the ball 12 on the oiling roller 11, and the friction between the steel wire 4 and the ball 12 is used to drive the ball 12 to rotate, so that the ball 12 adheres to the oil and enters the steel wire 4, thereby realizing the oiling of the steel wire 4.
