Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to an anti-sway device for cranes with stable lifting. Background Art

[0002] Gantry crane is a variation of bridge crane, also called gantry crane. It is mainly used for loading and unloading operations of outdoor cargo yards, material yards and bulk cargo. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. It is widely used in port cargo yards. Its metal structure is like a door-shaped frame. Two legs are installed under the load-bearing main beam. It can walk directly on the track on the ground. Both ends of the main beam can have an outward cantilever beam. Due to the large size of the gantry crane and the large operating space, the hanging equipment is also large in size. The hooks used in traditional gantry cranes only use multiple steel ropes to achieve anti-sway.

[0003] For example, the application number is CN202121172764.0. The utility model discloses an anti-sway hoist for a gantry crane, which relates to the technical field of gantry cranes. The utility model includes a machine body, and the machine body is slidably connected to an electric hoist on the upper surface of the beam, and the machine body is slidably connected to an expansion plate on the lower surface of the beam. The lifting rope connected to the electric hoist passes through the beam and is fixedly connected to a hook frame at the bottom end. By arranging a slidable expansion plate on the bottom surface of the crane's beam, two movable anti-sway arms are arranged on the hook frame connected to the hook, and the top of the anti-sway arm slides with the expansion plate. When the hook moves up and down, the two anti-sway arms are driven to expand and contract back and forth, thereby not only not affecting the up, down, left and right movement of the hook, but also inserting a positioning plate on the frame, thereby further limiting the forward and backward movement of the hook, ensuring that the hook does not swing when hanging equipment. Compared with the traditional method of using multiple steel wires to achieve anti-sway, it completely limits the forward, backward, left and right swing of the hook, and has higher stability.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that the equipment is large in size and the equipment sways more violently when the electric hoist slides left and right, and the steel rope still has a certain toughness, and swinging is inevitable, but during use, it is necessary to lubricate the machine body regularly to ensure that the machine body is maintained for long-term use. However, the crane is not equipped with a device to remind the user to lubricate the machine body, which may easily cause the machine body to not be lubricated for a long time, thereby reducing the life of the machine body.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 3 As shown, the utility model provides an anti-sway device for a crane with stable lifting, comprising a support frame 1, a body 2, an electric hoist 3, a vertical plate 4, a hook 5 and a positioning plate 6. The top of the support frame 1 is fixedly connected to both sides of the bottom of the body 2, the bottom of the surface of the electric hoist 3 is slidably connected to the inner wall of the body 2, the top of the vertical plate 4 is fixedly connected to both sides of the bottom of the body 2, the bottom of the electric hoist 3 is fixedly connected to the top of the hook 5 through a lifting rope, both sides of the surface of the positioning plate 6 are slidably connected to the inner wall of the vertical plate 4, the positioning plate 6 runs from the left side to the right side of the hook 5, infrared sensors 7 are inlaid on both sides of the inner wall of the body 2, a control box 8 is fixedly connected to the right side of the top of the body 2, and the control box 8 is electrically connected to the infrared sensor 7 through a wire, a sound box 9 is inlaid on the bottom of the outer side of the vertical plate 4 away from the control box 8, and the sound box 9 is electrically connected to the control box 8 through a wire, and a recording component 10 is fixedly connected to the bottom of the outer side of the vertical plate 4 close to the control box 8.

[0023] refer to Figure 3 The recording assembly 10 includes a mounting bar 101 , the left side of which is fixedly connected to the bottom of the outer side of the vertical plate 4 close to the control box 8 , and a placement box 102 is slidably connected to the surface of the mounting bar 101 .

[0024] As a technical optimization solution of the utility model, by setting the recording component 10, first align the left side of the placement box 102 with the top of the installation strip 101, and move the placement box 102 downward to connect the placement box 102 with the installation strip 101. Whenever the user inspects and maintains the body 2 once, the maintenance information can be recorded on paper, and the paper with this information can be placed inside the placement box 102, so that the user can understand the previous maintenance information next time.

[0025] refer to Figure 3 Slide grooves 11 are provided on both sides of the top of the placement box 102 , and a cover plate 12 is slidably connected to the inner wall of the slide groove 11 .

[0026] As a technical optimization solution of the utility model, by setting the slide groove 11 and the cover plate 12, when the user puts the paper with recorded information into the placement box 102, the left side of the cover plate 12 is aligned with the slide groove 11, and the cover plate 12 is moved toward the vertical plate 4, so that the cover plate 12 is connected to the placement box 102. The cover plate 12 can prevent the paper from being soaked by rainwater, thereby achieving the effect of protecting the paper.

[0027] refer to Figure 1 The front and back sides of the vertical plate 4 are inlaid with light strips 13, and the light strips 13 are electrically connected to the control box 8 through wires.

[0028] As a technical optimization solution of the utility model, by setting the light bar 13, when the number of signals received by the control box 8 reaches the threshold set by the user, the control box 8 will control the sound box 9 to emit a sound to remind the user, and will also turn on the light bar 13. The light bar 13 can prevent the user from not being able to hear the sound of the sound box 9 at a distance and being unable to quickly understand the signal that the body 2 needs maintenance.

[0029] refer to Figure 3 The bottom of the mounting bar 101 is fixedly connected with a baffle 14 , and the top of the baffle 14 is movably connected with the bottom of the placement box 102 .

[0030] As a technical optimization solution of the utility model, by setting the baffle 14, when the user installs the placement box 102, the baffle 14 can block the final moving distance of the placement box 102, allowing the user to install the placement box 102 more conveniently, thereby achieving the effect of assisting the installation of the placement box 102.

[0031] refer to Figure 3 A magnetic block 15 is fixedly connected to the inner side of the inner wall surface of the slide groove 11 , and the right side of the magnetic block 15 is magnetically adsorbed to the bottom of the left side of the cover plate 12 .

[0032] As a technical optimization solution of the utility model, by setting a magnetic block 15, when the user moves the cover plate 12 to the inner side of the inner wall surface of the slide groove 11, the cover plate 12 can be adsorbed into the slide groove 11 by using the magnetic block 15, so as to avoid the situation that the cover plate 12 automatically detaches from the slide groove 11 when the machine body 2 starts to work and vibrates, thereby achieving the effect of making the cover plate 12 more stable.

[0033] refer to Figure 3 Auxiliary bars 16 are fixedly connected to both sides of the top of the cover plate 12, and a plurality of auxiliary bars 16 are provided and distributed at equal distances.

[0034] As a technical optimization solution of the utility model, by setting the auxiliary strip 16, when the user needs to move the cover plate 12 out of the slide groove 11, the auxiliary strip 16 can be used to increase the friction between the user and the cover plate 12, making it easier for the user to slide the cover plate 12, thereby achieving the effect of assisting the sliding of the cover plate 12.

[0035] The working principle and use process of the utility model are as follows: first, align the left side of the placement box 102 with the top of the installation strip 101, and move the placement box 102 downward to connect the placement box 102 with the installation strip 101. The baffle 14 can be used to block the final moving distance of the placement box 102, so that the user can install the placement box 102 more conveniently. Whenever the user inspects and maintains the machine body 2 once, the maintenance information can be recorded on a piece of paper, and the paper recording the information can be placed inside the placement box 102, so that the user can learn about the last maintenance information next time. When the user puts the paper recording the information into the placement box 102, the maintenance information can be recorded on the paper. When the machine body 2 is in contact with the infrared sensor 7, the infrared sensor 7 transmits the number of times the machine body 2 is touched to the control box 8. When the number reaches the threshold, the control box 8 turns on the sound box 9 to remind the user and also turns on the light bar 13. The light bar 13 can prevent the user from not being able to hear the sound of the sound box 9 at a distance and not being able to quickly understand the signal that the machine body 2 needs to be maintained, thereby achieving the effect of auxiliary reminder.

[0036] In summary, the anti-sway device for the crane with stable lifting is provided with an infrared sensor 7, a control box 8 and a sound box 9. Whenever the machine body 2 touches the infrared sensor 7, the infrared sensor 7 transmits the number of times the machine body 2 is touched to the control box 8. When the number reaches a threshold, the control box 8 turns on the sound box 9 to remind the user, thereby solving the problem of needing to lubricate the machine body regularly to ensure that the machine body is maintained for long-term use. However, the crane is not provided with a device to remind the user to lubricate the machine body, which may easily lead to the machine body not being lubricated for a long time, thereby reducing the life of the machine body.
