Description

Technical Field

[0001] The present application relates to the field of crane accessory equipment, and in particular to a high-stability electric hoist. Background Art

[0002] Electric hoist is a special lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places.

[0003] The electric hoist has a compact structure. The motor axis is perpendicular to the drum axis. The electric hoist adopts a worm gear transmission device. Its disadvantages are: large length and width, bulky structure, low mechanical efficiency, difficult processing, etc. The hydraulic system is double-controlled, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. The electrical control department adopts low-voltage control to increase the safety of the control system.

[0004] When the electric hoist in the prior art is transporting objects, it is affected by the kinetic force and wind force. The steel rope for lifting materials is very likely to shake and sway, and there is a large friction between the materials and the inner side of the hook, which causes the hook and the steel rope to be severely damaged, and further causes the steel rope to break easily, causing the object to fall, resulting in a large amount of property loss and also easily causing safety risks. At the same time, when there is a large friction between the steel rope and the hook, the object will also shake significantly, making the operation extremely unstable when transporting objects.

[0005] For this reason, we propose a high-stability electric hoist to further improve the electric hoist in the prior art. Summary of the invention

[0019] 1. Taking into account the shaking and swaying problem of goods when they are hoisted into the air due to the influence of movement force and wind force, the present application is provided with a support member and a clamping member. When hoisting heavier goods, the user can control the clamping ring on the clamping member to clamp to the end of the telescopic column on the support member, so that the moving platform controlled by the main steel rope and the support member are integrated into one, thereby increasing the lateral area of ​​the main steel rope. When hoisting heavy goods and in windy weather, the provided support member can limit the left and right directions of the main steel rope, so that the main steel rope is restricted instead of swinging left and right. When hoisting lighter goods and in windless conditions, there is no need to integrate the moving platform and the support member.

When lifting the goods, the connecting rope of the goods can be directly hooked in the indented groove. At the same time, by rotating the turning handle, the turning handle drives the threaded turning rod to rotate, thereby driving the two auxiliary bevel gears meshing on both sides of the main bevel gear to rotate, so that the pressing rod moves on it through the slider, and tightens the connecting rope of the goods hooked in the indented groove, thereby avoiding the shaking problem caused by the large friction between the material and the inner side of the hook.

When the clamping member is not in use, it can be prevented from blocking the lifted goods. At the same time, the storage can protect the clamping member.

[0022] 4. The elastic rope is connected through a locking ring and installed on the locking hooks on the telescopic column and the limit block. This setting allows the elastic rope to be disassembled to avoid elastic fatigue caused by long-term use of the elastic rope.

[0023] 5. The hook is connected to the balance seat through a secondary steel rope. The buffer spring provided can buffer and reduce shock for the hook hung on the balance seat, further avoiding the problem of hook shaking caused by vibration. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. Example

[0036] See also Figures 1 to 9 The present invention provides a high-stability electric hoist, comprising a bracket 1 and an electric hoist body 2, wherein the bracket 1 is provided with a leg 3 at the bottom, and a foot 4 is provided at the lower end of the leg 3, and a slide bar 5 is provided inside the bracket 1.

[0037] The lower end of the electric hoist body 2 is installed with a fixing seat 14, and the lower end of the fixing seat 14 is movably connected with a support member, and the support member includes a telescopic column 15, a lock hook 17, an elastic rope 18 and a limit block 16. The telescopic column 15 is installed on the fixing seat 14 by bolts, and the bottom end of the telescopic column 15 is fixedly connected to the limit block 16. The left and right sides of the telescopic column 15 and the limit block 16 are fixedly connected with a lock hook 17, and the lock hook 17 is installed in the elastic rope 18. The left and right sides of the telescopic column 15 are also provided with reinforcing ribs;

[0038] Taking into account the shaking and swaying problem of the goods when they are hoisted into the air due to the influence of movement force and wind force, the present application is provided with a support member and a clamping member. When hoisting heavier goods, the user can control the clamping ring 38 on the clamping member to clamp to the end of the telescopic column 15 on the support member, so that the moving platform 7 controlled by the main steel rope 6 is integrated with the support member, thereby increasing the lateral area of ​​the main steel rope 6. When hoisting heavy goods and in windy weather, the provided support member can limit the left and right directions of the main steel rope 6, so that the main steel rope 6 will not sway left and right due to the restriction. When hoisting lighter goods and in a windless state, there is no need to integrate the moving platform 7 with the support member. At this time, the telescopic column 15 is stored under the electric hoist by the elastic force of the elastic rope 18, and will not cause obstruction to larger goods. At the same time, the provided reinforcing rib plate can further improve the supporting strength of the telescopic column 15.

[0039] The hook 13 is provided with a cavity and a through groove, and a pressing piece is provided in the cavity, and the pressing piece includes a rotating handle 19, a threaded rotating rod 20, a main bevel gear 21, a secondary bevel gear 3422 and a threaded column 23. The rotating handle 19 is fixedly connected with a threaded rotating rod 20, and the threaded rotating rod 20 is rotatably connected in the through groove of the hook 13. One end of the threaded rotating rod 20 is connected with the main bevel gear 21, and the left and right sides of the main bevel gear 21 are rotatably connected with the secondary bevel gear 22. One end of the secondary bevel gear 22 is connected with a threaded column 23, and the other end is rotatably connected with a fixed block, and the fixed block is fixedly connected to the inner wall of the hook 13, and a slider 24 is slidably connected to the outer wall of the threaded column 23, and the upper end of the slider 24 is fixedly connected with a pressing rod 25;

[0040] Taking into account the problem of greater friction between the material and the inner side of the hook, the present application provides a recessed groove on a part of the hook surface of the hook 13, and also provides a pressing piece. When lifting the goods, the connecting rope of the goods can be directly hooked in the recessed groove. At the same time, by rotating the handle 19, the handle 19 drives the threaded rotating rod to rotate, thereby driving the two secondary bevel gears 22 meshing on both sides of the main bevel gear 21 to rotate, so that the pressing rod 25 moves on it through the slider 24, and tightens the connecting rope of the goods hooked in the recessed groove, thereby avoiding the shaking problem caused by the greater friction between the material and the inner side of the hook.

[0041] A telescopic member is installed on the partition, and the telescopic member includes an electric telescopic rod 26, a mounting seat 27 and a connecting rod 28. The output end of the electric telescopic rod 26 is installed with the mounting seat 27, and the front end of the mounting seat 27 is connected to one end of the connecting rod 28 through a rotating shaft, and the other end of the connecting rod 28 is installed with a slide plate 29 through a rotating shaft.

[0042] The clamping member can be controlled to move inside the movable platform 7 by means of the telescopic member, and the clamping member can be stored by the movement, so that the clamping member can be prevented from blocking the lifted goods when not in use, and the storage can protect the clamping member.

[0043] A clamping member is installed at the upper end of the slide plate 29, and the clamping member includes a motor 30, a second connecting rod 31, a third connecting rod 32, a tooth plate 33, a gear 34, a mounting plate 35, a fourth connecting rod 36, a fifth connecting rod 37 and a clamping ring 38. An inner groove is opened on the partition plate, and the slide plate 29 is slidably connected in the inner groove through a telescopic member;

[0044] The output shaft of the motor 30 is rotatably connected with a connecting rod 2 31, the front end of the connecting rod 2 31 is movably connected with a connecting rod 3, one end of the connecting rod 3 is connected with a toothed plate 33, the upper and lower sides of the toothed plate 33 are meshed with gears 34, the gear 34 is mounted on a mounting plate 35 through a rotating shaft, a connecting rod 4 36 is mounted on the side wall of the gear 34, and a connecting rod 5 37 is also mounted on the slide plate 29, the height of the connecting rod 4 36 is the same as that of the connecting rod 5 37, and a clamping ring 38 is movably connected to the side walls of the connecting rods 4 36 and 5 37;

[0045] See also Figure 7-Figure 8As shown, when it is necessary to clamp the telescopic column 15, the user controls the electric telescopic rod 26 to retract. During retraction, the slide plate 29 is driven to slide in the inner groove of the partition plate of the moving platform 7 through the connecting rod 1 28, so that it slides out of the moving platform 7 and reaches the position of the telescopic column 15 of the support. Then the user controls the two motors 30 on the slide plate 29. The motor 30 drives the connecting rod 2 31 and the connecting rod 3 32 to rotate through the output shaft, and pulls the tooth plate 33 to move horizontally while rotating. Because the tooth plate 33 and the gear 34 are meshed, the tooth plate 33 drives the clamping ring 38 connected by the connecting rod 4 36 and the connecting rod 5 37 on the gear 34 to move relative to each other when moving horizontally, thereby clamping the telescopic column 15, so that the moving platform 7 controlled by the main steel rope 6 is integrated with the support, thereby increasing the lateral area of ​​the main steel rope 6. When lifting heavy weight goods and in strong windy weather, the provided support can limit the left and right directions of the main steel rope 6, so that the main steel rope 6 does not swing left and right due to restriction.

[0046] The left and right ends of the elastic rope 18 are both provided with locking rings. The elastic coefficient of the elastic rope 18 is relatively small, and it can only limit the telescopic column 15, and does not affect the rise and fall of the hook 13;

[0047] See also Figure 1 As shown, the telescopic column 15 is elastically connected to the lock hook 17 through an elastic rope 18, and the elastic rope 18 is hooked on the telescopic column 15 and the lock hook 17 on the limit block 16 through a lock ring, and the telescopic column 15 forms an elastic structure with the limit block 16 through the elastic rope 18;

[0048] The elastic coefficient of the elastic rope 18 is small and will not hinder the hook 13 from descending. The elastic rope 18 can only limit the telescopic column 15 to ensure that the telescopic column 15 is in a storage state when not in use and will not fall and block the lifting of goods.

[0049] See also Figure 1 and Fig. 9 As shown, the elastic rope 18 is connected by a locking ring and installed on the locking hook 17 on the telescopic column 15 and the limit block 16. This arrangement allows the elastic rope 18 to be disassembled to avoid elastic fatigue caused by long-term use of the elastic rope 18.

[0050] A portion of the hook surface of the hook 13 is recessed.

[0051] The support member and the clamping member are in the same horizontal plane, and the level of the clamping ring 38 in the clamping member is higher than the height of the limit block 16 of the support member;

[0052] See also Figure 1 As shown, the above arrangement enables the clamping ring 38 to be clamped just above the limit block 16 when extended, and the limit block 16 blocks the hook 13 so that the telescopic column 15 can be directly pulled downward when it descends.

[0053] Working principle: When heavy goods need to be lifted or goods need to be lifted in windy weather, the user controls the electric telescopic rod 26 to retract. When retracting, the link 1 28 drives the slide plate 29 to slide in the inner groove of the partition plate of the moving platform 7, so that it slides out of the moving platform 7 to the position of the telescopic column 15 of the support. Then the user controls the two motors 30 on the slide plate 29. The motor 30 drives the link 2 31 and the link 3 32 to rotate through the output shaft, and pulls the tooth plate 33 to move horizontally at the same time. Because the tooth plate 33 is meshed with the gear 34, the tooth plate 33 drives the link on the gear 34 when it moves horizontally. The clamping ring 38 connected to the rod 4 36 and the connecting rod 5 37 moves relatively, so that the clamping ring 38 is clamped to the upper end position of the upper limit block 16 of the telescopic column 15, so that the moving platform 7 controlled by the main steel rope 6 is integrated with the support member, so that the hook 13 changes from point lifting to surface lifting, thereby increasing the lateral area of ​​the main steel rope 6. When lifting heavy goods and in strong windy weather, the support member can limit the left and right directions of the main steel rope 6, so that the left and right directions of the main steel rope 6 are limited, and the hook 13 will not swing left and right when it rises. At the same time, the reinforcing rib plate can provide support force for the telescopic column 15;

[0054] At the same time, considering the problem of large friction between the material and the inner side of the hook, the present application provides a recessed groove on a part of the hook surface of the hook 13, and also provides a pressing piece. When lifting the goods, the connecting rope of the goods can be directly hooked in the recessed groove, and then the user rotates the turning handle 19, and the turning handle 19 drives the threaded turning rod to rotate, thereby driving the two auxiliary bevel gears 22 meshing on both sides of the main bevel gear 21 to rotate, so that the pressing rod 25 moves on it through the slider 24, and tightens the connecting rope of the goods hooked in the recessed groove, avoiding the shaking problem caused by large friction between the material and the inner side of the hook; the telescopic piece can be used to control the movement of the clamping piece inside the moving platform 7, and the clamping piece can be stored by moving, so that when the clamping piece is not in use, it can be avoided that it blocks the lifted goods, and the storage can protect the clamping piece. The above is the working principle of a high-stability electric hoist.

[0055] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and its improved conception, which should be covered by the protection scope of the present application.
