Description

Technical Field

[0001] This utility model relates to the field of crane drum technology, and in particular to a novel drum for tower cranes. Background Technology

[0002] Tower cranes are one of the most commonly used pieces of equipment on construction sites. They are used to lift various building materials and construction machinery, which can greatly improve the efficiency of construction. The drum is an important component of the tower crane, used to wind the wire rope.

[0003] Traditional wire rope reels often suffer from uneven cable arrangement when winding up wire rope. Because wire rope is prone to twisting, overlapping, or crossing during winding, the wire rope inside the drum is not neatly arranged, affecting the efficiency of lifting operations. Furthermore, manually applying oil to extend the service life of the wire rope is usually done by workers, which is quite cumbersome. Utility Model Content

[0017] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-3 This utility model provides a novel drum for a tower crane, comprising a housing 1, a drum 2 rotatably mounted inside the housing 1, a cable inlet 3 at the center of the lower side wall of the housing 1, and a cable routing mechanism 4 inside the housing 1. The cable routing mechanism 4 includes a fixed base 41, support plates 42, a reciprocating screw 43, limiting rods 44, a reciprocating block 45, and a cable routing ring 46. The fixed base 41 is fixedly connected to the rear inner wall of the housing 1, and support plates 42 are fixedly connected to both sides of the front side wall of the fixed base 41. A reciprocating screw 43 is rotatably mounted between the two support plates 42, and two limiting rods 44 are also fixedly connected between the two support plates 42. A reciprocating block 45, which cooperates with the reciprocating screw 43, is slidably sleeved between the positioning rods 44. The reciprocating screw 43 can make the reciprocating block 45 reciprocate without changing the direction of rotation. A wire guide ring 46 is fixedly connected to the front side wall of the reciprocating block 45. When the drum 2 rotates, it drives the reciprocating screw 43 to rotate through the transmission. When the reciprocating screw 43 rotates, it can cause the reciprocating block 45 to drive the wire guide ring 46 to move back and forth along the limiting rod 44. When the wire guide ring 46 moves, it drives the wire rope to move, so that the wire rope can be neatly wound on the drum 2. A lubrication mechanism 5 is provided in the wire inlet 3.

[0021] Specifically, such as Figure 3 As shown, a novel drum for a tower crane includes a lubrication mechanism 5 comprising an oil reservoir 51, an oil channel 52, a ball seat 53, and ball bearings 54. The oil reservoir 51 is fixedly connected to the lower inner wall of the housing 1. Multiple ball seats 53 are arranged in the inner ring of the inlet 3. Multiple oil channels 52 are provided on the lower inner wall of the housing 1 to connect the oil reservoir 51 and the ball seats 53. Ball bearings 54 are movably arranged inside the ball seats 53. The lubricating oil in the oil reservoir 51 enters the ball seat 53 through the oil channel 52 under gravity. When the wire rope passes through the inlet 3, the friction causes the ball bearings 54 to rotate. When the ball bearings 54 rotate, they carry out the lubricating oil in the ball seat 53, thus coating the wire rope with oil.

[0022] Specifically, such as Figure 1 and Figure 2As shown, a new type of drum for tower cranes has a drive gear 21 fixedly sleeved at one end of the drum 2, and a driven gear 431 meshing with the drive gear 21 is fixedly connected to one end of the reciprocating screw 43. When the drum 2 rotates, it can drive the drive gear 21 to rotate together. When the drive gear 21 rotates, it will cause the driven gear 431 meshing with it to drive the reciprocating screw 43 to rotate. The reciprocating screw 43 rotates with the rotation of the drum 2. No additional power source is required, and the operating cost is low.

[0023] Specifically, such as Figure 2 As shown, a new type of drum for tower cranes has a soft, wear-resistant inner liner 461 inside the cable guide ring 46 to prevent direct friction between the cable guide ring 46 and the wire rope.

[0024] Specifically, such as Figure 2 As shown, a new type of drum for tower cranes has an annular oil storage tank 51, which will not obstruct the winding and unwinding of the wire rope.

[0025] Specifically, such as Figure 3 As shown, a new type of drum for tower cranes has an oil filling port 511 on the upper side wall of the oil storage tank 51, through which lubricating oil is added into the oil storage tank 51.

[0026] It should be noted that this utility model is a new type of drum for tower cranes. When the output shaft drives the drum 2 to rotate, the drum 2 winds up the wire rope. The wire rope enters the housing 1 through the inlet 3. When the drum 2 rotates, it drives the drive gear 21 to rotate. The drive gear 21 rotates, which causes the driven gear 431 to drive the reciprocating screw 43 to rotate. When the reciprocating screw 43 rotates, it causes the reciprocating block 45 that cooperates with it to drive the wire guide ring 46 to move back and forth along the limit rod 44. When the wire guide ring 46 moves, it drives the wire rope to move, so that the wire rope can be neatly wound on the drum 2. The lubricating oil in the oil reservoir 51 enters the ball seat 53 through the oil passage 52 under the influence of gravity. When the wire rope passes through the inlet 3, the friction will drive the ball 54 to rotate. When the ball 54 rotates, it will carry out the lubricating oil in the ball seat 53 and apply oil to the wire rope.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
