Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, in particular to a follow-up hopper with an anti-falling structure. Background Technique

[0002] A portal crane, usually used for loading and unloading with a grab bucket or a hook, mostly runs along the crane track on the ground or on a building for lifting and loading and unloading operations. The follow-up hopper is mainly used for direct loading and unloading of bulk goods such as coal and ore onto ships. When in use, it is lifted by a portal crane and a suspension rope.

[0003] For example, the patent with the publication number CN216189456U: A hopper of a ship unloader with an anti-falling function, including a driving disc, a hopper installed below the driving disc, and a suspension rope connected to the driving disc. Two fixing plates are installed on both sides of the top end of the driving disc. In the utility model, when an abnormality occurs on one side of the supporting plate, or when one of the end blocks is fractured and deformed, the rubber pad at the top end of the fixing ring abuts against the anti-falling cover plate. The suspension rope located in this perforation is subjected to an increased force. After the pressure sensor receives the pressure signal, it transmits the signal to the electric control box, so that the alarm of the electric control box emits a beep, thereby warning the staff in advance that the hopper may fall, so as to enable timely maintenance of the connection of the hopper, greatly reducing the occurrence of safety accidents.

[0004] There are still some deficiencies in the above patent. For example, when one of the suspension ropes breaks, the supporting plate and the rack on it will fall downward as a whole for a certain distance, resulting in poor meshing of the rack, and then making the hopper unstable and tilting to one side, causing the material to fall from it; during the process of loading and lifting the hopper, when the pulling force at the moment of lifting is too large, or when the hopper jumps up and down due to uneven lifting speed, it is easy to cause the suspension rope to break, and then cause the hopper to fall from a high altitude.

[0005] Therefore, we propose a follow-up hopper with an anti-falling structure to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a follow-up hopper with an anti-falling structure to solve the problems that when one of the suspension ropes breaks, the hopper is unstable and tilts to one side, causing the material to fall from it, and during the process of loading and lifting the hopper, when the pulling force at the moment of lifting is too large, or when the hopper jumps up and down due to uneven lifting speed, it is easy to cause the suspension rope to break, and then cause the hopper to fall from a high altitude, as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A follow-up hopper with a fall prevention structure, including a hopper body and a connection port fixedly arranged at the bottom of the hopper body. Hoisting components are embedded and slidably connected on the side walls on both sides of the hopper body. Elastic components are symmetrically embedded and slidably connected on the top surface of each hoisting component. A suspension rope is fixedly connected to the top end of each elastic component. Balancing components are fixedly connected to the side walls on both sides of the hopper body. The balancing components are arranged at the top end of the hoisting component on the same side and are meshed and connected with the hoisting component.

[0008] Preferably, semi-circular chutes are opened on the side walls on both sides of the hopper body, and limiting chutes are opened on the inner cavity side walls of each semi-circular chute.

[0009] Preferably, the hoisting component includes two connection seats respectively arranged on the side walls on both sides of the hopper body. The connection seats are arc-shaped structures. A plurality of connection columns are fixedly connected to the side walls of each connection seat. Each connection column abuts and slides against the inner cavity side wall of the semi-circular chute on the same side. A limiting pulley is rotatably connected to the side wall of each connection column. Each limiting pulley is rotatably clamped inside the limiting chute. A plurality of limiting teeth are fixedly connected to the inner ring side wall of each connection seat.

[0010] Preferably, grooves are symmetrically opened on the top surface of each connection seat, and limiting rings are fixedly connected to the inner wall of the top end of each groove;

The top surface of the limiting plate and the bottom surface of the limiting ring are elastically connected by a spring, and the corresponding connecting rod penetrates through the inner ring of the spring.

[0012] Preferably, the balancing component includes a first gear shaft and a second gear shaft fixedly connected to the side wall of the hopper body.

[0013] Preferably, the moving gear is meshed and connected with the fixed gear, and the moving gear is meshed and connected with the inner ring of the connection seat through the limiting teeth.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. By arranging the hoisting component and the elastic component, during hoisting, the suspension rope is fixedly connected with the connecting rod in the elastic component.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4, A follow-up hopper with a fall prevention structure, including a hopper body 1 and a connection port 6 fixedly arranged at the bottom of the hopper body 1. Lifting components 2 are embedded and slidably connected to the side walls on both sides of the hopper body 1. Elastic components 3 are symmetrically embedded and slidably connected to the top surfaces of each lifting component 2. A suspension rope 4 is fixedly connected to the top end of each elastic component 3. Balance components 5 are fixedly connected to the side walls on both sides of the hopper body 1 to temporarily maintain the balance of the hopper body 1 when one end of the suspension rope 4 breaks, preventing it from tipping over and causing the material to fall. The balance component 5 is arranged at the top end of the lifting component 2 on the same side and is meshed and connected to the lifting component 2.

[0025] Semicircular chutes 11 are provided on the side walls on both sides of the hopper body 1, and limiting chutes 12 are provided on the inner cavity side walls of each semicircular chute 11.

[0026] The lifting component 2 includes two connection seats 21 respectively arranged on the side walls on both sides of the hopper body 1. The connection seats 21 are of arc-shaped structures. A plurality of connection columns 22 are fixedly connected to the side walls of each connection seat 21. Each connection column 22 abuts and slides against the inner cavity side wall of the semicircular chute 11 on the same side. A limiting pulley 23 is rotatably connected to the side wall of each connection column 22. Each limiting pulley 23 is rotatably clamped inside the limiting chute 12, enabling the connection seat 21 to slide along the semicircular chute 11 and preventing it from falling off. The friction resistance during its sliding is reduced through the setting of the limiting pulley 23, thereby ensuring its sliding sensitivity. A plurality of limiting teeth 24 are fixedly connected to the inner ring side walls of each connection seat 21.

[0027] Grooves 211 are symmetrically provided on the top surfaces of each connection seat 21, and limiting rings 212 are fixedly connected to the inner wall at the top end of each groove 211;

[0028] The elastic component 3 includes a connecting rod 31 slidably arranged inside the groove 211. One end of the connecting rod 31 is fixedly connected with a limiting plate 32, and the other end of the connecting rod 31 is fixedly connected with the suspension rope 4. The connecting rod 31 can slide inside the groove 211 through the limiting plate 32 and the limiting ring 212 and will not slip out of it. The limiting plate 32 abuts and slides against the inner cavity side wall of the groove 211. The top surface of the limiting plate 32 and the bottom surface of the limiting ring 212 are elastically connected through a spring 33, and the corresponding connecting rod 31 penetrates through the inner ring of the spring 33. Thus, when the suspension rope 4 is subjected to excessive tensile force, the connecting rod 31 can slide outwards along the groove 211 and compress the spring 33, and the suspension rope 4 can be prevented from breaking under the action of elastic buffering.

[0029] In this embodiment: When the hopper body 1 is hoisted, the lifting rope 4 is fixedly connected to the connecting rod 31 in the elastic component 3. During the hoisting process of the hopper body 1, when the instantaneous tension received by the lifting rope 4 is too large, it can drive the connecting rod 31 to slide outward along the groove 211 and buffer through the elastic force of the spring 33, so as to avoid the instantaneous tension received by the lifting rope 4 being too large and breaking, resulting in the high-altitude fall of the hopper body 1.

[0030] Embodiment 2

[0031] This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 2 and Figure 3 , the balance component 5 includes a first gear shaft 51 and a second gear shaft 52 fixedly connected to the side wall of the hopper body 1. A moving gear 53 is rotatably connected to the side wall of the first gear shaft 51, and a fixed gear 54 is fixedly connected to the side wall of the second gear shaft 52.

[0032] The moving gear 53 is meshed and connected with the fixed gear 54, and the moving gear 53 is meshed and connected with the inner ring of the connecting seat 21 through the limiting teeth 24.

[0033] In this embodiment: Through the settings of the fixed gear 54 and the moving gear 53, when the moving gear 53 rotates in one direction, the fixed gear 54 can inhibit the movement in this direction, and when the rotational force is large enough, the rotational direction of the fixed gear 54 is opposite to that of the moving gear 53, so as to correct the inclination of the hopper body 1 connected to the fixed gear 54.

[0034] Working principle: During hoisting, the lifting rope 4 is fixedly connected to the connecting rod 31 in the elastic component 3. During the hoisting process of the hopper body 1, when the instantaneous tension received by the lifting rope 4 is too large, it can drive the connecting rod 31 to slide outward along the groove 211 and buffer through the elastic force of the spring 33. When one of the lifting ropes 4 breaks abnormally, the other lifting rope 4 on the same side drives the connecting seat 21 to slide along the semi-circular chute 11 to one side. At this time, the hopper body 1 has a tendency to tilt towards the broken side. When the connecting seat 21 slides, the moving gear 53 is rotated through the limiting teeth 24, and then a reverse acting force is applied to the fixed gear 54, so that a reverse deflection force is generated in the direction of the tilt of the hopper body 1, keeping the hopper body 1 stable.
