Description

Technical Field

[0001] The utility model relates to a steel wire rope electric hoist, belonging to the technical field of hoisting equipment. Background Art

[0002] At present, the electric wire rope hoist is a commonly used lifting equipment, such as the "electric wire rope hoist" disclosed in Chinese patent CN202924645U, which drives the drum through the motor reducer to control the lifting and lowering of the wire rope on the drum. However, in order to achieve structural balance, one end of the wire rope is tied to the frame and the other end is wound on the drum, so that the hook assembly is located in the center. As a result, its overall structure is complex and its overall bearing capacity is insufficient. When the specifications are different, the frame size needs to be readjusted after the size of the motor drum is changed to achieve the center of gravity balance of the hook assembly, which is not conducive to the large-scale mass production of products of different specifications by manufacturers. Summary of the invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a wire rope electric hoist constructed in a modular manner, which can conveniently match the needs of customers with different lifting specifications.

[0004] The purpose of the utility model is achieved in this way:

[0005] A wire rope electric hoist includes a drum, a motor assembly and a reducer, wherein a wire rope is wound on the drum, and the drum, the motor assembly and the reducer are all installed on a bracket assembly, and the bracket assembly includes two mutually parallel support plates 1 and 2, a connecting piece is fixedly connected between the support plates 1 and 2, the drum and the motor assembly are installed between the support plates 1 and 2, the reducer is installed on the outer side wall of the support plate 1, a driving end of the motor assembly passes through the support plate 1 and is connected to the input end of the reducer, and one end of the drum passes through the support plate 1 and is connected to the output end of the reducer.

[0006] Preferably, two steel wire ropes are wound on the drum, and the two steel wire ropes are respectively wound from two ends of the drum and then connected to the hook connector together.

[0007] Alternatively, the middle of a wire rope is connected to a hook connector, and both ends of the wire rope are wound onto both ends of a drum.

[0008] Preferably, the wire rope electric hoist also includes a rope pressing assembly, which includes a guide rod connected to support plate one and support plate two, a rope pressing block is slidably arranged on the guide rod, the rope pressing block is attached to the wire rope of the drum, and a rope pressing groove is arranged on the rope pressing block for the wire rope to be embedded.

[0009] Preferably, the guide rod is connected to the rope pressing block via a spline.

[0010] Preferably, two guide rods are provided.

[0011] Preferably, both ends of the support plate 1 and the support plate 2 are respectively covered with decorative covers, and the support plate 1 and the support plate 2 are covered with an outer shell cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model adopts a modular design concept and utilizes a bracket assembly formed by a support plate one, a support plate two and a connecting piece to realize the installation of a drum, a motor assembly, a wire rope, a reducer and an electronic control component, thereby not only improving the overall carrying capacity, but also when it is necessary to adjust the lifting power (replacing motors of different powers) and the lifting length (replacing drums of different lengths) according to customer needs, it is only necessary to adjust the length of the connecting piece to achieve a perfect match, without spending extra costs on redesign and redevelopment, which greatly shortens the research and development cycle and reduces development and production costs.

[0014] At the same time, the wire rope in the utility model is wound on the drum from both ends to the middle, so that the hook connector connected to the hook is always located directly below the center of the drum, so that the hook is always located below the center of gravity of the drum during the working process of the wire rope, ensuring the balance of force and making the lifting more stable. It can be used in new energy batteries and other occasions with higher requirements on stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figures 1 to 7 The utility model relates to an electric wire rope hoist, which includes a bracket assembly 1 carrying a drum 2, a motor assembly 3, a reducer 5 and an electronic control assembly 6. The bracket assembly 1 includes a support plate 11, a support plate 12, a connecting piece 13 and a hanging piece 14. The support plate 11 and the support plate 12 are located at the left and right ends and are vertically parallel. The support plate 11 and the support plate 12 are fixedly connected by the connecting piece 13, and the connecting piece 13 of the rod-shaped structure is provided with three rods to form a triangular stable structure. The hanging piece 14 is fixed to the two connecting pieces 13 located above.

[0029] The drum 2 and the motor assembly 3 are installed between the support plate 1 11 and the support plate 2 12. Specifically, the two ends of the drum 2 are installed on the support plate 1 11 and the support plate 2 12 through bearings. Two steel wire ropes 4 are wound on the drum 2. The two steel wire ropes 4 are wound from the two ends of the drum 2 and are connected to the hook connector 41; or the middle of a steel wire rope 4 is connected to the hook connector 41, and the two ends of the steel wire rope 4 are wound to the two ends of the drum 2 (the steel wire rope 4 is wound in a symmetrical manner, so that during the process of lifting the goods by the hook connected to the hook connector 41, the steel wire ropes 4 at both ends are unwound or reeled synchronously, so that the goods are always in the middle position, which not only has better load-bearing performance but also better stability); the motor assembly 3 includes a motor body 31 and a coupling 32 installed on the output end of the motor body 31. The motor body 31 and the coupling 32 are fixedly installed on the support plate 2 12 and the support plate 1 11 respectively.

[0030] Preferably, in order to ensure the stability of the wire rope 4 during the lifting and lowering process and prevent it from slipping out of the spiral groove on the drum 2, a rope pressing assembly 7 is also provided to limit the wire rope 4, ensuring that the wire rope 4 is firmly pressed on the drum 2 during operation. The rope pressing assembly 7 includes a guide rod 71 connected to the support plate 1 11 and the support plate 2 12, and a rope pressing block 72 is slidably provided on the guide rod 71 (the guide rod 71 is connected to the rope pressing block 72 through a spline; or two guide rods 71 ​​are provided to ensure the stable left and right movement of the rope pressing block 72), the rope pressing block 72 is attached to the wire rope 4 of the drum 2, and a rope pressing groove 73 is provided on the rope pressing block 72 for the wire rope 4 to be embedded. Therefore, in the process of the drum 2 retracting and releasing the wire rope 4, due to the close pressing of the rope pressing block 72, the rope pressing block 72 is pressed on the wire rope 4 under the restriction of the guide rod 71, and is driven by the wire rope 4 to move left and right.

[0031] The reducer 5 and the electronic control component 6 are respectively installed on the support plate 1 11 and the support plate 2 12, and the output end of the coupling 32 of the motor assembly 3 passes through the support plate 1 11 and is connected to the input end of the reducer 5, and the output end of the reducer 5 is connected to the reel 2 to drive the reel 2 to rotate.

[0032] Finally, decorative covers 8 are respectively mounted on both ends of the support plate 1 11 and the support plate 2 12 to cover the reducer 5 and the electronic control component 6 respectively; and an outer shell cover 9 is mounted between the support plate 1 11 and the support plate 2 12 to cover the drum 2 and the motor 3, and the hanging piece 41 passes through the top of the outer shell cover 9, and the wire rope 4 passes through the bottom of the outer shell cover 9.
