A bidirectional conical helical mechanism with buffer damping

Abstract

This utility model discloses a bidirectional conical spiral mechanism with buffer damping, including a gantry crane and a freight container. The gantry crane has a compensation mechanism near the entrance for adjusting the material inside the freight container. This compensation mechanism controls the amount of material transported inside the freight container. When the freight volume is overloaded, the compensation mechanism removes excess material; when the freight volume is less than the set value, the compensation mechanism adds material inward, and then levels the container. This utility model uses two opposing conical augers to move material from the edges of the freight container towards the center during rotation, thus better leveling the coal surface. This effectively solves the problem of unsatisfactory leveling effects in existing coal leveling mechanisms, allowing for more even spreading of coal inside the freight container, reducing the risk of spillage during transportation, and improving the safety and efficiency of coal transportation. Combined with a telescopic rod with buffering function, it controls the conical augers to make flexible contact with the material, extending the equipment's service life.

Description

Technical Field

[0001] This utility model relates to the field of spiral coal leveling structure technology, specifically a bidirectional conical spiral mechanism with buffer damping. Background Technology

[0002] In the field of coal production and transportation, the spiral leveling mechanism of the coal leveler plays a crucial role. Its main principle is to evenly spread the coal in the cargo box through the rotation of the spiral blades. During the rotation of the spiral blades, the friction and thrust between the spiral blades and the coal cause the coal to redistribute in the cargo box, thereby achieving the effect of leveling the coal surface. This leveling method can effectively improve the safety and efficiency of coal transportation and ensure that the loading state of the coal in the cargo box meets the transportation requirements.

[0003] During the material transfer process in coal mines, gantry cranes equipped with spiral coal leveling mechanisms are often used to level the materials inside the cargo box, preventing the risk of spillage during transportation. However, existing spiral coal leveling mechanisms have a relatively simple structure and can usually only perform unidirectional coal leveling operations. The leveling effect on coal inside the cargo box is not ideal, especially when the coal distribution inside the cargo box is uneven or the coal is piled up near the edge of the cargo box side rails. Existing coal leveling mechanisms cannot completely level the coal surface, and it is easy for local coal to be piled up too high or too low. In addition, existing coal leveling mechanisms have limited functions and cannot be flexibly adjusted according to different coal characteristics and cargo box shapes, making it difficult to meet the complex and ever-changing coal transportation needs.

[0004] Therefore, a bidirectional conical helical mechanism with buffer damping is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional conical spiral mechanism with buffer damping, comprising a gantry crane and a freight container. The gantry crane has a compensation mechanism for adjusting the materials inside the freight container on one side near the entrance. The outer wall of the gantry crane has a moving mechanism, and a lifting device is connected to one side of the moving mechanism. The outer wall of the lifting device is connected to telescopic rods, and the outer walls of the two telescopic rods are rotatably connected to a flat material auger. The flat material auger is formed by connecting two oppositely arranged conical augers. When rotating, it controls the materials on both sides to move towards the center.

[0007] Preferably, the flat auger is internally connected to a first drive device, and both telescopic rods are connected to the first drive device.

[0008] Preferably, the moving mechanism includes guide rails that are fixedly installed on the outer side wall of the gantry crane, and a lifting platform is slidably connected to the outer side walls of the two guide rails.

[0009] Preferably, the compensation mechanism includes a material lifting cylinder disposed on one side of the entrance end of the gantry crane, and a material lifting auger is rotatably connected inside the material lifting cylinder. The lower end of the material lifting auger is tapered to facilitate insertion into the material for material retrieval.

[0010] Preferably, the compensation mechanism further includes a drive shaft with a fixed connecting shaft at the upper end of the lifting auger, the upper end of the drive shaft is connected to a third drive device, and the shaft wall of the drive shaft is rotatably connected to a mounting plate, which is detachably mounted on the gantry crane tower.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses two oppositely arranged conical augers to move the material on both sides of the cargo box towards the center when rotating, thereby better leveling the coal surface. This effectively solves the problem of unsatisfactory leveling effect of existing coal leveling mechanisms, and can more evenly spread the coal in the cargo box, reducing the risk of coal spillage during transportation and improving the safety and efficiency of coal transportation. At the same time, with the help of a telescopic rod with a buffer function, the conical augers are controlled to make flexible contact with the material, thereby improving the service life of the equipment.

[0015] 2. The compensation mechanism of this utility model can compensate or remove the coal according to the specific conditions of the coal in the cargo box through the lifting auger, so that the loading and distribution of the coal are more in line with the transportation requirements. In addition, the setting of the compensation mechanism also enables the coal leveling mechanism to be flexibly adjusted according to different coal characteristics and cargo box shape, so as to meet the complex and ever-changing coal transportation needs, make up for the single function of the existing coal leveling mechanism, and greatly improve the applicability and practicality of the coal leveling mechanism.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a bidirectional conical spiral mechanism with buffer damping, including a gantry crane 1 and a freight container 2. The gantry crane 1 has a compensation mechanism near the entrance end for adjusting the material inside the freight container 2. The compensation mechanism controls the amount of material transported inside the freight container 2. When the freight volume is overloaded, the compensation mechanism removes excess material; when the freight volume is less than the set value, the compensation mechanism adds material inward, and then levels the container. The outer wall of the gantry crane 1 has a moving mechanism 7, and one side of the moving mechanism 7 is connected to a lifting device 6. The outer wall of the lifting device 6 is connected to a telescopic mechanism. The outer walls of the two telescopic rods 5 are rotatably connected to a flat material auger 3. The flat material auger 3 is composed of two oppositely arranged conical augers. When rotating, it controls the material on both sides to move towards the middle. It should be noted that the lifting mechanism 6 can be a cylinder or a long screw. Driven by components such as motors and gears, it controls the telescopic rods 5 with a buffering effect and the oppositely arranged conical augers to move into the interior of the cargo box 2. Since the material inside the cargo box is uneven, the conical auger is driven to rotate, controlling the material on both sides to fill the middle, so that the material that was about to overflow near the outside of the cargo box moves to the middle, preventing the material from spilling during the transfer.

[0023] The flat material auger 3 is internally connected to a first drive device 4, and two telescopic rods 5 are both connected to the first drive device 4. The telescopic rods 5 work with the lifting device 6 to control the conical auger to make flexible contact with the material, so as to prevent the equipment from being damaged.

[0024] In this embodiment, the moving mechanism 7 includes guide rails 16 that are fixedly installed on the outer side wall of the gantry crane 1. The outer side walls of the two guide rails 16 are slidably connected to a lifting platform 13. A second drive device 14 is connected to one side of the lifting platform 13. The output end of the second drive device 14 is connected to a drive wheel. A gear 15 is meshed with one side of the drive wheel. The gear 15 is fixedly connected to the gantry crane 1.

[0025] In this embodiment, the compensation mechanism includes a material lifting cylinder 8 located on one side of the entrance end of the gantry crane 1. A material lifting auger 9 is rotatably connected inside the material lifting cylinder 8. The lower end of the material lifting auger 9 is tapered to facilitate insertion into the material for material retrieval.

[0026] The compensation mechanism also includes a drive shaft 10 with a fixed connection shaft at the upper end of the lifting auger 9. A third drive device 11 is connected to the upper end of the drive shaft 10. A mounting plate 12 is rotatably connected to the shaft wall of the drive shaft 10. The mounting plate 12 can be detachably installed on the gantry crane 1.

[0027] In this embodiment, both the leveling auger 3 and the first driving device 4 are matched with the size of the inner wall of the cargo container 2. The leveling auger 3 is moved into the cargo container 2 by the lifting device 6 for leveling operation.

[0028] The bottom of the gantry crane 1 and the freight container 2 are respectively connected to multiple sets of first moving wheels 17 and second moving wheels 18, which are used to control the movement of the gantry crane 1 and the freight container 2, so that the conical auger can be controlled to move and level during the leveling process, making the leveling application range wider.

[0029] The working principle is as follows: In actual operation, the core principle of this utility model is to achieve precise positioning and operation of the leveling auger 3 through the cooperation of the gantry crane 1, the moving mechanism 7, and the lifting device 6. Specifically, the leveling auger 3 consists of two oppositely arranged conical augers. When rotating, it can push the coal on both sides of the cargo box towards the center, thereby achieving a uniform leveling effect. During the leveling process, the telescopic rod 5 and the first drive device 4 work together to ensure that the leveling auger 3 can flexibly contact the coal and avoid equipment damage. At the same time, the lifting device 6 controls the lifting of the leveling auger 3, so that it can adapt to cargo boxes of different heights. In addition, the setting of the compensation mechanism further enhances the functionality of this utility model. The lifting auger 9 is located in the lifting cylinder 8 on one side of the entrance end of the gantry crane 1. Its lower end is conical, which facilitates insertion into the coal for material retrieval or compensation operations. When the coal loading in the cargo box is insufficient or unevenly distributed, The third drive device 11 drives the lifting auger 9 to rotate, thereby replenishing or removing coal and ensuring that the loading and distribution of coal in the cargo box meet transportation requirements. The drive shaft 10 of the compensation mechanism is detachably mounted on the gantry crane 1 via the mounting plate 12 for easy maintenance and replacement. The moving mechanism 7 includes a guide rail 16 fixed to the outer wall of the gantry crane 1 and a slidingly connected lifting platform 13. The lifting platform 13 is driven by the second drive device 14 to move the drive wheel along the toothed rail 15, thereby moving the lifting device 6 up and down, which in turn drives the leveling auger 3 to the designated position. The first moving wheel 17 and the second moving wheel 18 at the bottom of the gantry crane 1 and the cargo box 2 are used for the movement of the entire equipment, expanding the applicability of the leveling operation. Through the coordinated operation of the above components, this utility model can effectively solve the problems of unsatisfactory leveling effect and single function of existing coal leveling mechanisms, and significantly improve the safety and efficiency of coal transportation.
