Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyor preparation, and particularly relates to a damping buffer device with a reusable weight configured for a belt. Background Art

[0002] The length of a single section of the belt of a belt conveyor is also relatively long, and some are even hundreds of meters long. Therefore, it is very necessary to tension the belt, and usually a hanging weight is used to achieve this. The weights of the weights vary, ranging from several hundred catties to over a thousand catties. Once the belt breaks and the weight falls, it will cause serious damage to the buildings, platforms, etc. below, and even cause safety accidents.

[0003] In the original design, used tires, sand boxes, spring boxes, etc. are placed below the weight as a buffer structure for receiving the weight. However, these methods can only play a buffering role, and the weight after falling deeply sinks into the underlying structure and cannot be reused. Summary of the Invention

[0004] In view of the above defects, the present invention provides a damping buffer device with a reusable weight configured for a belt, including a buffer net, a left pulley group, a left steel wire, a left counterweight cart, a left buffer, a right pulley group, a right steel wire, a right counterweight cart, and a right buffer; the buffer net is arranged directly below the weight, the left pulley group and the right pulley group are symmetrically arranged on both sides of the buffer net, one end of the left buffer is fixedly connected to an external base body, and the other end is connected to the left counterweight cart. The other end of the left counterweight cart is wound around the left pulley group through a left steel wire rope and is connected to the buffer net; one end of the right buffer is fixedly connected to the external base body, and the other end is connected to the right counterweight cart. The other end of the right counterweight cart is wound around the right pulley group through a right steel wire rope and is connected to the buffer net.

[0005] This solution is different from other designs. This solution can not only buffer the weight and prevent it from instantly falling and damaging the underlying structure, but also temporarily store the potential energy of the weight through a flexible mechanism, and then convert it into the kinetic energy of the weight being lifted, making it as close to its original position as possible. Brief Description of the Drawings

[0007] Figure 2 It is a schematic diagram of another embodiment of the present invention.

[0010] Figure 5 It isFigure 4 Schematic diagram of the force principle

[0011] In the figure: buffer net 10, left pulley block 21, guide pulley 211, fixed pulley 212, first movable pulley 213, second movable pulley 214, third movable pulley 215, left steel wire 22, left counterweight vehicle 23, left buffer 24, right pulley block 31, right steel wire 32, right counterweight vehicle 33, right buffer 34, guide sleeve 35, spring 36, magnet group 37, single magnet 371, weight 100. Specific implementation mode

[0012] See Figure 1 、 3 As shown in

[0013] In this solution, when the weight 100 falls, it is first received by the buffer net 10, and then the counterweight vehicle is pulled closer to the middle. In this solution, the buffer net 10 serves as a primary buffer structure, the counterweight vehicle serves as a secondary buffer structure, and the buffer serves as a tertiary buffer structure. After three - level buffering, the impact force of the falling weight is greatly absorbed, reducing the impact, and the gravitational potential energy of the weight is converted into the kinetic energy of the counterweight vehicle moving closer to the middle and the elastic potential energy of the buffer, which is temporarily stored. When the weight is stable, it means that all its gravitational potential energy has been converted. At this time, the elastic potential energy stored in the buffer is released, converted into kinetic energy, pulling the counterweight vehicle back to its original position, and then pulling the buffer net 10 to rise, lifting the weight upward to be as close to the original position as possible.

[0014] This solution is different from other designs. This solution can not only buffer the weight, avoiding damage to the underlying structure caused by its instantaneous fall, but also temporarily store the potential energy of the weight through a flexible mechanism, and then convert it into the kinetic energy of the weight being lifted, making it as close to the original position as possible.

[0015] Furthermore, the right buffer 34 and the left buffer 24 are springs 36.

[0016] Further, the right buffer 34 and the left buffer 24 are magnet groups.

[0017] Further, the magnet group includes at least three single magnets 37, and the three single magnets are assembled in a way that opposite poles attract each other.

[0018] See Figure 4 、 5 Furthermore, a frame is fixedly arranged on the ground foundation. The left pulley group includes a guide wheel 211 and a bearing wheel group. The bearing wheel group includes a fixed pulley 212, a first movable pulley 213, a second movable pulley 214, and a third movable pulley 215. The fixed pulley is fixedly installed at the top of the frame. The second movable pulley and the third movable pulley are arranged on both sides of the fixed pulley. The first movable pulley is arranged below the fixed pulley. The first movable pulley is flexibly connected to the second movable pulley and the third movable pulley. The left steel wire rope winds around the third movable pulley, one end is connected to the buffer net, and the other end is connected to the left counterweight vehicle. In this solution, through the arrangement of three movable pulleys and one fixed pulley, the force F of the falling weight is decomposed. As shown in the figure, the two half-sections L1 and L2 of the left steel wire rope respectively bear F / 2, and the force borne by the flexible connection between the upper second movable pulley, third movable pulley, and fixed pulley is F / 4, greatly reducing the acting force on a single flexible connection and avoiding other problems such as fracture caused by concentrated and excessive stress.

[0019] Further, the guide wheel 211 is arranged at the lower part of the frame. In the original solution, the guide wheel was arranged on an external foundation. Although it is a guide wheel, it also bears a large force from the steel wire rope. And according to the force analysis, when the weight falls, the F / 2 borne by L2 is decomposed by the guide wheel into F1 and F2. Among them, F2 is conducted to the frame through the arrangement on the frame. And through the arrangement of the upper second movable pulley and third movable pulley, the fixed pulley receives a downward force F3, and this acting force acts on the frame. So the upper part of the frame bears a downward force. This acting force F3 is opposite to F2 in direction and both act on the frame. The same frame bears two acting forces in opposite directions at the same time, which offset each other, forming internal consumption and promoting the stability of the frame itself. Compared with arranging the guide wheel on an external foundation, the force borne by the guide wheel is greatly reduced, and the problem of the guide wheel breaking due to too large an acting force is avoided.

[0020] In the present invention, the right pulley group and the left pulley group can adopt the same structure to achieve the same effect.

[0021] Further, a guide sleeve 35 is also arranged outside several magnets. One end of the guide sleeve 35 is fixedly connected to the left counterweight vehicle 23, and the other end is fixedly connected to the external base body. The guide sleeve 35 is made of a non-metallic material that is not adsorbed by the magnets. The setting of the guide sleeve 35 provides a guiding space for the three-section monomer magnets. After being instantaneously separated by force, their positions will not deviate greatly. After the counterweight vehicle stabilizes, the magnets with opposite polarities attract each other and adsorb close again, pulling up the buffer net 10 to help the heavy hammer lift and restore to its original position.

[0022] The embodiments of the present solution have been described in detail above with reference to the accompanying drawings. However, the present solution is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
