Description

Technical Field

[0001] The present application relates to the technical field of belt conveyors, and in particular to an adjustable grooved angle buffer bed for belt conveyors. Background Art

[0002] Belt conveyor is one of the indispensable and important equipment in mining production. It has been widely used in many industries such as coal mines due to its high efficiency, large capacity, flexibility and economy. The conveyor belt is driven by an electric motor to circulate along the roller on the frame, thereby realizing continuous material transportation.

[0003] The buffer bed is a buffer device located under the conveyor belt of the belt conveyor. Its main function is to absorb and disperse the impact force generated when the material falls, prevent these impact forces from directly acting on the conveyor belt, and thus avoid the conveyor belt from being worn, torn or deformed due to long-term impact. The buffer bed is usually composed of buffer strips, buffer brackets and connectors. Among them, the buffer strip is the core component, which is made of special rubber materials with high elasticity, wear resistance, flame retardancy and antistatic. These buffer strips are closely arranged on the buffer bracket to form a flat contact surface, which realizes surface-to-surface contact with the conveyor belt. The buffer bracket is responsible for supporting and fixing the buffer strip to ensure that it remains stable during use. When the material falls from a high place, the first thing it touches is the buffer strip on the buffer bed of the belt conveyor. The buffer strip absorbs and disperses the impact force through the physical elastic deformation of its rubber material, so that the material can fall smoothly on the conveyor belt. This surface-to-surface contact method not only effectively reduces the damage to the conveyor belt caused by the impact force, but also makes the material more evenly stressed during the conveying process, avoiding material splashing and leakage caused by uneven stress.

[0004] Among them, the buffer support of the belt conveyor buffer bed includes an intermediate frame and side frames arranged on both sides of the intermediate frame. The buffer support is an overall groove-shaped structure. The inventor knows that the angle between the existing buffer bed side frame and the intermediate frame is fixed, that is, the groove angle is fixed. Therefore, after the working environment changes, it is necessary to design an overall replacement for the buffer bed with a different groove angle. The process is cumbersome and complicated, and increases the equipment cost.

[0005] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art. Summary of the invention

[0006] In view of at least one of the above technical problems, the present disclosure provides a belt conveyor with an adjustable groove angle buffer bed, which aims to solve the technical problem that the existing buffer bed has a fixed groove angle and thus has poor adaptability to working conditions.

[0007] According to one aspect of the present disclosure, there is provided an adjustable trough angle buffer bed for a belt conveyor, including a plurality of buffer frames installed between the beam bodies of the belt conveyor and used for installing buffer strips. The buffer frame includes a cross beam with an intermediate frame fixed at the middle position, side frames respectively arranged on both sides of the intermediate frame and hinged to the cross beam at the corresponding ends, adjusting screws perpendicularly arranged at both ends of the cross beam, adjusting sleeves sleeved outside the adjusting screws, and limit nuts threadedly connected to the adjusting screws and correspondingly limiting the adjusting sleeves on both sides of the adjusting sleeves; a chute is arranged along the length direction at the bottom of the side frame, a connecting rod perpendicular to the central axis of the adjusting sleeve is fixedly arranged outside the adjusting sleeve, and a sliding rod slidably fitted into the chute is fixedly arranged at the end of the connecting rod.

[0008] In some embodiments of the present disclosure, hinge seats are respectively arranged on both sides of the cross beam at the intermediate frame, and hinge plates corresponding to the hinge seats are arranged at the bottom of the side frame.

[0009] In some embodiments of the present disclosure, a stop block for limiting the position of the limit nut is fixedly arranged at the top of the adjusting screw.

[0010] In some embodiments of the present disclosure, a buffer washer for clamping between the limit nut and the adjusting sleeve is sleeved outside the adjusting screw, and the buffer washer is made of rubber.

[0011] In some embodiments of the present disclosure, the chutes are symmetrically arranged on both sides of the side frame.

[0012] In some embodiments of the present disclosure, the sliding rod is perpendicular to the connecting rod, and the length of the sliding rod is not less than the distance between the two chutes.

[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0014] 1. The hinge connection between the hinge plate at the bottom of the side frame and the hinge seat enables the angle between the side frame and the intermediate frame to be correspondingly adjusted according to the requirements of the actual use environment, and the environmental adaptability is relatively strong.

[0015] 2. By moving the adjusting sleeve along the adjusting screw, the sliding rod is driven to move along the chute, thereby realizing the adjustment of the inclination angle of the side frame. The adjustment process is convenient and fast, and any inclination angle of the side frame can be selected within the moving range of the adjusting sleeve.

[0016] 3. The buffer washer can absorb the impact of the device vibration on the limit nut through its elastic characteristics, thereby avoiding the problem that the loosening of the limit nut causes the change of the inclination angle of the side frame. Description of the Drawings

Detailed implementation manners

[0020] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0021] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0022] To solve the technical problem of poor adaptability of the existing fixed trough-shaped angle buffer bed, this example discloses an adjustable trough-shaped angle buffer bed for a belt conveyor. Refer to Figure 1 , which includes a plurality of buffer frames erected between the beam bodies of the belt conveyor and used for installing buffer strips. Specifically, the buffer frame includes a cross beam 1, an intermediate frame 2 and a side frame 3. Screw holes are provided at the bottoms of both ends of the cross beam for bolted fixed connection with the beam body of the belt conveyor. In this embodiment, the intermediate frame 2 is arranged at the middle position of the cross beam 1 and is detachably fixedly connected to the cross beam 1 by bolts. The side frames 3 are respectively hinged on both sides of the intermediate frame 2. Thus, by adjusting the included angle between the two side frames 3 and the intermediate frame 2, the adaptability adjustment of the trough-shaped angle of the buffer bed is realized, and further the use requirements of its use environment are met.

[0023] In order to realize the adaptability adjustment of the included angle between the side frame 3 and the intermediate frame 2, that is, the trough-shaped angle, in this embodiment, refer to Figure 1 , the side frame 3 is hingedly connected to the cross beam 1. Specifically, hinge seats 11 are respectively fixedly provided at the top surface positions on both sides of the intermediate frame 2 of the cross beam 1. Correspondingly, hinge plates 12 matching with the hinge seats 11 are fixedly arranged at the bottom of one end side of the side frame 3. Through the hinge shaft passing through the hinge seat 11 and the hinge plate 12, the hinged connection between the side frame 3 and the cross beam 1 is realized, so that the side frame 3 can rotate around the hinge seat 11 through the hinge plate 12, thereby realizing the corresponding adjustment of the trough-shaped angle of the buffer bed.

[0024] Specifically, to adjust the angle between the side frame 3 and the intermediate frame 2, refer to Figure 1 , adjusting screws 4 are fixedly provided at both ends of the cross beam 1. The adjusting screws 4 are perpendicular to the cross beam 1. An adjusting sleeve 5 is sleeved outside the adjusting screw 4. The inner diameter of the adjusting sleeve 5 matches the outer diameter of the adjusting screw 4, so that the adjusting sleeve 5 can be slidably sleeved outside the adjusting sleeve 5. In addition, refer to Figure 2 , a connecting rod 61 is fixedly provided at the outer edge of the adjusting sleeve 5. The connecting rod 61 is perpendicular to the axis of the adjusting sleeve 5, that is, the two are perpendicular to each other. A sliding rod 62 is fixedly provided at the end of the connecting rod 61. The sliding rod 62 is perpendicular to the connecting rod 61. Correspondingly, a sliding groove 7 is provided along the length direction of the side frame at the bottom of the side frame 3. The sliding rod 62 is slidably fitted in the sliding groove 7. Thus, when the adjusting sleeve 5 moves up and down along the adjusting screw 4, the connecting rod fixed thereto drives the sliding rod 62 to move accordingly. And because the sliding rod 62 is slidably fitted in the sliding groove 7, the angle between the side frame 3 and the cross beam is adjusted by the sliding of the sliding rod 62 along the groove.

[0025] Among them, in this embodiment, the sliding grooves 7 are symmetrically arranged on both sides of the side frame 3. Refer to Figure 1 , the groove wall of the sliding groove 7 is of a U-shaped structure. The two ends of the U-shaped groove wall are respectively welded and fixed to the bottom surface of the side frame 3. Thus, a strip-shaped sliding groove 7 is formed between the bottom surface of the side frame and the groove wall. Further, the connecting rod 61 is connected to the middle of the sliding rod 62. Thus, the connecting rod 61 and the sliding rod 62 form a T-shaped structure, and the length of the sliding rod 62 is not less than the distance between the two sliding grooves 7, so that both ends of the sliding rod 62 are slidably fitted into the sliding grooves on both sides of the side frame 3. In addition, in this embodiment, the outer edge of the sliding rod 62 is tangent to the sliding groove 7 during sliding, thus avoiding the problem that the side frame 3 shakes due to the gap between the sliding rod 62 and the sliding groove 7 after the position of the sliding rod 62 is relatively fixed. In some other embodiments, only one sliding groove is provided, and the corresponding end of the sliding rod is slidably fitted into the sliding groove.

[0026] In addition, since the adjusting sleeve 5 is sleeved outside the adjusting screw 4, after the side frame 3 is stressed, the load will be transmitted to the adjusting sleeve 5 through the sliding rod and the connecting rod, causing the adjusting sleeve 5 to slide relative to the adjusting screw 4, resulting in an undesired change in the groove angle. For this reason, in this embodiment, refer to Figure 1 , limit nuts 8 are respectively provided on both sides of the adjusting sleeve 5, and the two limit nuts 8 are respectively threadedly connected to the adjusting screw 4. Thus, by adjusting the positions of the two limit nuts 8, the relative fixation of the position of the adjusting sleeve 5 is realized. In addition, in this embodiment, buffer washers are respectively clamped between the two limit nuts 8 and the adjusting sleeve 5. The buffer washers are rubber parts, sleeved on the adjusting screw, and clamped between the adjusting sleeve and the limit nut. Part of the vibration during the operation of the equipment is absorbed by it, thus preventing the limit nuts 8 from loosening.

[0027] When adjusting the trough angle of the buffer bed, first loosen the two limit nuts. After adjusting the angle between the side frame and the intermediate frame to an appropriate angle, tighten the two limit nuts correspondingly so that the limit nuts limit the adjusting sleeve on both sides of the adjusting sleeve. In addition, in this embodiment, in order to prevent the limit nut from falling off the adjusting screw, a stop block is fixedly provided at the top position of the adjusting screw, and the stop block is threadedly connected to the adjusting screw, thereby realizing the limitation of the limit nut through the stop block.

[0028] Although some preferred embodiments of the present application have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of its inventive concept. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application is also intended to include these modifications and variations.
