Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to an electric hoist for horizontal lifting. Background Technology

[0002] Electric hoists are a common type of lifting equipment. They are compact, lightweight, easy to operate, convenient to use, and have high lifting efficiency. Therefore, electric hoists are widely used in industrial and mining enterprises, warehouses, and docks. Electric hoists can generally be divided into wire rope electric hoists and chain electric hoists. Among them, wire rope electric hoists are more widely used due to their smoother operation.

[0003] Chinese patent CN204038889U, entitled "A Suspended Wire Rope Electric Hoist," discloses an electric hoist in which the traveling trolley and the hoist itself are perpendicular to each other, thus freeing the hoist from the length limitation of its working space and allowing for a longer travel length. However, based on the accompanying drawings in its specification... Figure 2 It is known that the hook device of the electric hoist moves along the length of the electric hoist as the wire rope is wound and unwound. During the lifting process, the horizontal movement of the hook device causes the center of gravity of the electric hoist to change with the height of the load. At the same time, the center of the hook device is not on the same straight line as the I-beam rail, resulting in unstable stress on the electric hoist. This places severe demands on the mechanical strength of the electric hoist, the traveling trolley, and the I-beam rail, which greatly limits the use of the electric hoist. Utility Model Content

[0004] This utility model provides a horizontally hoisting electric hoist to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a horizontally hoisting electric hoist includes a drum, one end of which is connected to a drive motor, and the other end of which is connected to a reducer. A traveling mechanism for moving the drum is installed on the top of the drum. The traveling mechanism is mounted on an I-beam rail. The central axis of the drum along its length is perpendicular to the central axis of the I-beam rail along its length. A shell is installed on the outer periphery of the drum. Two symmetrically arranged fixed pulley groups are installed on the shell. A hook bracket is installed below the drum. A hook body is installed on the hook bracket. A movable pulley group corresponding to the fixed pulley groups is installed on the hook bracket above the hook body. The wire rope on the drum is connected to the movable pulley group and the fixed pulley group and then fixed to the shell.

[0006] Preferably, the drum is a double drum, in which the ends of the two wire ropes pass over the corresponding movable pulley group, then pass upward over the corresponding fixed pulley group, and then pass over the movable pulley group corresponding to the wire rope again, and so on, and the ends of the wire ropes are fixedly connected to the shell after passing through the movable pulley group.

[0007] Preferably, the fixed pulley assembly is located on the inner wall of one side of the housing, the bottom of the housing is open, and an opening is provided on the housing below the fixed pulley assembly.

[0008] Preferably, the top of the shell is fixedly connected to two symmetrically arranged fixing beams, which are spaced apart and vertically arranged. Several mounting plates are fixedly connected to the outer side wall of the fixing beams, and the mounting plates on the two fixing beams are symmetrically arranged. The mounting plates are arranged along the length direction of the fixing beams, and the ends of the mounting plates extend to the outer side of the fixing beams.

[0009] The traveling mechanism includes multiple carriage components, which are connected to the mounting plate via connecting plates or to the fixed beam via connecting plates.

[0010] Preferably, there are three sports car components, with the mounting plate located on one side of the fixed beam. Two sports car components are connected to the mounting plate via connecting plates, and the other sports car component is connected to the fixed beam via a connecting plate.

[0011] Preferably, each sports car component has two connecting plates, and the two connecting plates are connected by a horizontally arranged connecting shaft.

[0012] Preferably, the connecting plate includes a mounting part and a connecting part. The mounting part has a rectangular structure, and the connecting part has a triangular structure. The mounting part and the connecting part are integrally formed. The connecting shaft passes through the connecting part, and the inner sidewall of the mounting part is rotatably connected to a traveling wheel.

[0013] Preferably, one or more of the sports car components are active sports cars, which are driven by a walking motor.

[0014] Preferably, the I-beam rail is a square I-beam.

[0015] Preferably, mounting grooves are provided on both sides of the mounting part, and guide wheels are rotatably connected in the mounting grooves. The outer side wall of the guide wheel is set to abut against the lower flange side wall of the I-beam rail.

[0016] The beneficial effects of this utility model are as follows: (1) By setting the drum horizontally and setting two sets of fixed pulleys and two sets of movable pulleys, the wire rope ends are wrapped around the movable pulleys and fixed pulleys several times and then fixed to the shell. During the wire rope winding and unwinding process, the hook body will not move horizontally. The center of gravity of the hook body is consistent with the I-beam rail, so that the electric hoist is more stable in terms of force and can lift heavy objects; (2) By eliminating the conventional T-shaped plate, the fixed beam is directly connected to the mounting plate, which improves the lifting height to a certain extent; (3) The bottom of the shell is open and the lower part of the side wall of the shell is opened, which makes it easy for the top of the hook bracket to be lifted to the bottom of the fixed pulley group, which also improves the lifting height to a certain extent. At the same time, it also avoids the hook bracket impacting the bottom of the drum and causing damage to the drum, reducing the risk of impact. Attached Figure Description

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] A type of horizontally hoisted electric hoist, such as Figure 1 and Figure 2As shown, the device includes a drum 1, with a drive motor 2 connected to one end and a reducer 3 connected to the other end. A traveling mechanism for moving the drum 1 is mounted on the top of the drum 1, and the traveling mechanism is mounted on an I-beam rail 4. The central axis of the drum 1 along its length is perpendicular to the central axis of the I-beam rail 4 along its length. A housing 5 is mounted on the outer periphery of the drum 1. The drive motor 2 and the reducer 3 are mounted on the outside of the housing 5. The connection method between the drive motor 2, the reducer 3, and the drum 1 and the housing 5 is existing technology and will not be described in detail here. Two symmetrically arranged fixed pulley groups 6 are mounted on the housing 5. A hook bracket 7 is mounted below the drum 1, and a hook body 8 is mounted on the hook bracket 7. A movable pulley group 9, corresponding to the fixed pulley groups 6, is mounted on the hook bracket 7 above the hook body 8. The wire rope 10 on the drum 1 is connected to the movable pulley group 9 and the fixed pulley group 6 and then fixed to the housing 5. The central axes of symmetry of the two fixed pulley blocks 6 coincide with the central axes of symmetry of the two movable pulleys, and these coincident central axes of symmetry also coincide with the central axis of symmetry of the I-beam rail 4 (along the vertical direction). This arrangement ensures that the center of the hook body 8 remains aligned with the center of the I-beam rail 4 during the lifting process, thereby improving the stability of the electric hoist and the I-beam rail 4 under stress and extending the service life of the electric hoist.

[0022] In another embodiment, the drum 1 is a double drum 1, that is, two steel wire ropes 10 are wound in the drum 1. The two steel wire ropes 10 are respectively associated with a movable pulley group 9 and a fixed pulley group 6. The ends of the two steel wire ropes 10 pass over the movable pulley group 9 corresponding to them, then pass upward over the fixed pulley group 6 corresponding to them, and then pass over the movable pulley group 9 corresponding to the steel wire rope 10 again. This process is repeated, and finally, the ends of the steel wire ropes 10 are fixedly connected to the housing 5 after passing through the movable pulley group 9. The number of pulleys in the movable pulley group 9 and the fixed pulley group 6 is set as needed. If the number of movable pulleys in the movable pulley group 9 is N, then the number of fixed pulleys in the fixed pulley group 6 is N-1, where N≥2. When N=2, the wire rope 10 passes through the movable pulley group 9, then around the fixed pulley group 6 on the same side, and then around the movable pulley group 9 on the same side before being fixed to the housing 5. If N=3, the wire rope 10 passes through the movable pulley group 9, then around the fixed pulley group 6 on the same side, and then around the movable pulley group 9 on the same side. After that, it passes through the fixed pulley group 6 and the movable pulley group 9 on the same side before being fixed to the housing 5. This design reduces the tilt angle of the wire rope 10, thereby reducing wear and increasing its service life. On the other hand, the hook body 8 will not move horizontally as the wire rope 10 is extended or retracted, ensuring that the center of the hook body 8 remains aligned with the center of the I-beam rail 4. This improves the stability of the electric hoist and the I-beam rail 4 under stress, further extending their service life.

[0023] In another embodiment, the fixed pulley assembly 6 is located on the inner wall of one side of the housing 5, while the drum 1 is located near the other side of the housing 5. Without affecting the normal operation of the fixed pulley assembly 6 and the drum 1, the fixed pulley assembly 6 is positioned as close as possible to the drum 1 to reduce the tilting of the wire rope 10 and to reduce the volume of the electric hoist. The bottom of the housing 5 is open, and an opening 11 is provided on the housing 5 below the fixed pulley assembly 6. The opening 11 is located on the lower part of the side wall of the housing 5, with its ends extending to the ends of both ends of the housing 5. The top of the opening 11 is located near the fixed pulley assembly 6 and is connected to the open end of the bottom of the housing 5. The opening 11 facilitates the winding of the wire rope 10. Furthermore, since the hook body 8 is located directly below the fixed pulley assembly 6, the opening 11 frees up space directly below the fixed pulley assembly 6, allowing the top of the hook bracket 7 to rise below the fixed pulley assembly 6, thereby increasing the lifting height to some extent.

[0024] In another embodiment, two symmetrically arranged fixed beams 12 are fixedly connected to the top of the housing 5. The two fixed beams 12 are spaced apart and vertically arranged. A plurality of mounting plates 13 are fixedly connected to the outer side wall of the fixed beams 12, and the mounting plates 13 on the two fixed beams 12 are symmetrically arranged. The mounting plates 13 are arranged along the length direction of the fixed beams 12, and the ends of the mounting plates 13 extend to the outer side of the fixed beams 12. The traveling mechanism includes multiple carriage assemblies, which are connected to the mounting plates 13 via connecting plates 14 or to the fixed beams 12 via connecting plates 14. The length and number of mounting plates 13 are adjusted according to the number of trolley components. For example, if there are four trolley components, mounting plates 13 are installed at both ends of the fixed beam 12, with two mounting plates 13 extending towards both ends of the fixed beam 12 to provide installation space for the trolley components. In this embodiment, there are three trolley components, and only one mounting plate 13 is provided, located at one end of the fixed beam 12. Two trolley components are connected to the mounting plate 13 via connecting plates 14, and the other trolley component is connected to the fixed beam 12 via connecting plates 14. In traditional electric hoist structures, a T-shaped plate with a T-shaped arrangement is also connected between the mounting plate 13 and the fixed beam 12. By directly connecting the mounting plate 13 to the fixed beam 12, the distance between the electric hoist and the I-beam rail 4 is reduced, thereby increasing the lifting height to a certain extent.

[0025] In another embodiment, each sports car component has two connecting plates 14, with the two connecting plates 14 located on the outermost side. The two connecting plates 14 are connected by a horizontally arranged connecting shaft 15. Accordingly, the connecting shaft 15 also passes through a mounting plate 13 or a fixing plate located between the two connecting plates 14, specifically depending on the location of the sports car component. Figure 2As shown, in the sports car assembly on the left, when the sports car assembly is connected to the mounting plate 13 via the connecting plate 14, the connecting plate 14 is located outside the mounting plate 13, and the connecting shaft 15 passes through the mounting plate 13 located between the two connecting plates 14; in the sports car assembly on the right, when the sports car assembly is connected to the fixed beam 12 via the connecting plate 14, the two connecting plates 14 are located outside the fixed beam 12, and the connecting shaft 15 passes through the fixed beam 12 located between the two connecting plates 14; and in the sports car assembly in the middle, the connecting plate 14 is located outside the mounting plate 13, and the connecting shaft 15 passes through the mounting plate 13 and the fixed beam 12 located between the two connecting plates 14.

[0026] In another embodiment, the connecting plate 14 includes a mounting portion 16 and a connecting portion 17. The mounting portion 16 has a rectangular structure, and the connecting portion 17 has a triangular structure. The mounting portion 16 and the connecting portion 17 are integrally formed. A connecting shaft 15 passes through the connecting portion 17. Wheels are rotatably connected to the inner sidewalls of the mounting portion 16. In traditional sports car assemblies, the mounting portion 16 and the connecting portion 17 are separate components. This design increases the workload of installation and production. The integrated design not only reduces the workload but also reduces the height of the connecting plate 14 to some extent, thereby increasing the lifting height to a certain degree.

[0027] In another embodiment, one or more of the vehicle components are active vehicles, which are driven by a walking motor 19. The active vehicles and the corresponding walking motor 19 drive structure are prior art and will not be described in detail here.

[0028] In another embodiment, the I-beam rail 4 is a square I-beam. By making the I-beam rail 4 square, the strength of the I-beam rail 4 is improved, and its service life is extended.

[0029] In another embodiment, mounting grooves are provided on both sides of the mounting portion 16, and guide wheels 18 are rotatably connected in the mounting grooves. Figure 1 (Not shown in the image) The outer wall of the guide wheel 18 is positioned to abut against the lower flange side wall of the I-beam rail 4. The guide wheel 18 improves the stability of the trolley assembly during movement.

[0030] Instructions for use: When using, select an appropriate number of movable pulley blocks 9 and fixed pulley blocks 6 as needed. After wrapping the end of the wire rope 10 around the movable pulley blocks 9 and fixed pulley blocks 6 several times, fix it to the housing 5. Start the drum 1, which drives the wire rope 10 to wind up and down. During the wind up and down of the wire rope 10, the hook body 8 will not move horizontally. The center of gravity of the hook body 8 is consistent with the I-beam rail 4, which makes the force on the electric hoist more stable and enables the lifting of heavy objects. By eliminating the conventional T-shaped plate and directly connecting the fixed beam 12 to the mounting plate 13, the lifting height is increased to a certain extent. At the same time, the bottom of the housing 5 is open and the lower part of the side wall has an opening 11, which makes it easy for the top of the hook bracket 7 to be lifted to below the fixed pulley block 6, which also increases the lifting height to a certain extent. At the same time, it also avoids the hook bracket 7 impacting the drum 1 and causing damage to the drum 1, reducing the risk of top impact.

[0031] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
