Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a buffer bed for belt conveyors. Background Art

[0002] The buffer bed plays a vital role in the smooth operation of the entire belt conveyor. A reasonable design can effectively cushion the impact of materials, reduce damage to the belt, and guide the material to prevent the belt from running off track. Traditional buffer beds are mostly composed of a beam plus a buffer strip structure. The steel structure such as the beam itself does not have a buffering effect. It basically relies on the high-elastic rubber buffer material in the buffer strip. However, the buffer strip has extremely limited buffering capacity when considering multiple factors such as wear resistance and elasticity. Therefore, it is still a rigid impact when falling materials, which will cause damage to both the buffer bed itself and the belt. Currently, most buffer beds on the market are designed based on the principle of rigid impact. Martin in the United States has improved the buffer strip structure and increased its buffering effect, but the overall principle of rigid impact is still used. Therefore, the overall buffering capacity of the buffer bed is limited. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a buffer bed for a belt conveyor, which has a secondary buffering effect and can reduce the impact on the buffer bed itself and the conveyor belt.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A buffer bed for a belt conveyor includes: a base assembly, a buffer bar base and a buffer bar, the buffer bar base includes a middle base and side bases located on both sides of the middle base, steel wire ropes are respectively provided on both sides of the base assembly, the steel wire ropes on both sides are arranged obliquely, and the two side bases are respectively installed parallel to the top of the steel wire ropes on both sides.

[0006] Furthermore, the base assembly includes a crossbeam at the bottom and columns installed at both ends of the crossbeam, and both ends of the steel wire rope are installed on the columns and the crossbeam respectively.

[0007] Furthermore, the steel wire rope is fixedly connected to the side base, the crossbeam and the column via a steel wire rope bayonet.

[0008] Furthermore, a mounting hole for installing the wire rope bayonet is opened on the side surface of the column, and there are multiple mounting holes located at different heights.

[0009] Furthermore, the middle base and the side base are respectively installed with a plurality of longitudinal beams, the longitudinal beams are arranged along the front-back direction, and buffer strips are fixed on the longitudinal beams in the same direction.

[0010] Furthermore, the steel wire ropes on each side are provided in a plurality in the front-to-back direction and are parallel to each other, and the side bases are provided in a plurality and correspond one-to-one to the steel wire ropes on the same side.

[0011] Furthermore, the crossbeam is connected to the column through a connecting beam to form an integrated structure, and a plurality of columns are provided and each of the columns corresponds one-to-one to the steel wire ropes on the same side.

[0012] After adopting the above technical solution, the beneficial effects of the utility model are:

[0013] Since the buffer bed for belt conveyor of the utility model includes: a base assembly, a buffer bar base and a buffer bar, the buffer bar base includes a middle base and side bases located on both sides of the middle base, steel wire ropes are respectively provided on both sides of the base assembly, and the steel wire ropes on both sides are inclined. The side bases on both sides are respectively installed parallel to the top of the steel wire ropes on both sides. When the buffer bed receives material, the material impacts the buffer bar, and the high-elastic rubber in the buffer bar plays a first-level buffering role on the falling material. The elasticity of the steel wire rope supporting the buffer bar itself plays a second-level buffering role on the material. The overall secondary buffering design has a greater buffering effect on the impact force of the material than the traditional rigid impact buffer bed, which can reduce the impact on the buffer bed itself and the conveyor belt.

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as limiting the scope of protection of the present invention.

[0018] like Figure 1As shown, a buffer bed for a belt conveyor comprises a base assembly 1, a base for buffer bars 5, and the buffer bars 5. The base for the buffer bars 5 comprises a central base 31 and side bases 32 located on either side of the central base 31. Steel wire ropes 2 are disposed on either side of the base assembly 1, with the steel wire ropes 2 arranged at an angle. The side bases 32 are mounted parallel to and above the steel wire ropes 2 on either side. When the buffer bed receives material, the buffer bars 5 provide the primary buffering effect for falling material, while the steel wire ropes 2 below provide the secondary buffering effect. This overall secondary buffering design significantly reduces the impact on the material, reducing the impact on the buffer bed itself and the conveyor belt.

[0019] The base assembly 1 includes a crossbeam 11 at the bottom and columns 13 mounted at each end of the crossbeam 11. The ends of the wire rope 2 are mounted to the columns 13 and crossbeam 11, respectively. The wire rope 2 is fixedly connected to the side base 32, crossbeam 11, and columns 13 via wire rope clips 21. Preferably, the side of the column 13 is provided with mounting holes 14 for receiving the wire rope clips 21. Multiple mounting holes 14 are provided, each located at different heights.

[0020] The staff can adjust the angle between the wire rope 2 and the crossbeam 11 by installing the wire rope bayonet 21 at different heights on the column 13 according to the installation position of the belt conveyor, the requirements of the belt buffer and the design angle, so as to achieve adjustable groove angles of the side buffer strip 5 and the wire rope 2. In this application, the angle between the wire rope 2 and the crossbeam 11 is preferably 10° to 45°.

[0021] like Figure 2 As shown, the middle base 31 and the side bases 32 are each mounted with multiple longitudinal beams 4, which are arranged in the front-to-back direction. Buffer strips 5 are fixed in the same direction on the longitudinal beams 4. In a specific embodiment of the present application, multiple steel wire ropes 2 are arranged in the front-to-back direction on each side and are parallel to each other. Multiple side bases 32 are provided and correspond one-to-one with the steel wire ropes 2 on the same side. Multiple middle bases 31 are also provided in the front-to-back direction and correspond one-to-one with the side bases 32.

[0022] Furthermore, the crossbeam 11 is connected to the column 13 through the connecting beam 12 to form an integrated structure. The column 13 is provided with multiple columns and corresponds one-to-one to the steel wire ropes 2 on the same side. The base assembly 1 is reliably connected to the buffer structure above, making the whole machine integrated and increasing the overall stability.

[0023] The buffer bed for belt conveyor of the utility model is provided with a steel wire rope between the buffer bar base and the base assembly on the side, and the steel wire ropes on both sides are arranged at an angle. When the buffer bed receives material, the buffer bar and the steel wire rope can respectively play a buffering role on the material. Therefore, the overall secondary buffering design of the present application has a greater buffering effect on the impact force of the material than the traditional rigid impact buffer bed, thereby reducing the impact on the buffer bed itself and the conveyor belt.
