Description

Technical Field

[0001] The invention relates to a modular heavy-duty buffer bed used for protecting a belt at a material drop point of a belt conveyor. Background Art

[0002] The importance of using a buffer bed to protect the conveyor belt of a belt conveyor has been highly recognized by users and is widely used. Existing buffer bed frames are welded from materials such as steel sections and steel plates, and have the following problems: 1. Each specification of belt conveyor requires different materials and tooling according to the center height (roller diameter), and belt conveyors of various specifications and models require a variety of materials and tooling; 2. Almost all of the connections between frame components are welded, resulting in many welding points and poor overall precision, so there are many hidden dangers, more materials and labor, and the welding process is prone to environmental pollution; 3. It is assembled and manufactured using ordinary materials, and needs to be painted after manufacturing, which is prone to environmental pollution during the painting process; 4 1. The existing adjustable groove angle buffer bed has a misunderstanding about the adjustable groove angle: the groove angle of the belt conveyor trough roller is fixed. The design of the buffer bed generally requires that the buffer bed surface is about 20mm lower than the upper plane of the conveyor roller (the bottom surface of the belt), and the groove angle surface is also 20mm lower. Since the buffer bed is mostly installed under the guide trough, it is easy to cause the guide trough to be poorly sealed. For this reason, some manufacturers have developed an adjustable groove angle buffer bed. Since the axis point of the groove angle part of the buffer bed is on the innermost side, the outer end adjustment changes the groove angle, which makes it difficult to meet the requirements of the guide trough sealing point. The effect is poor, and the structure is complex, which increases the manufacturing cost. 5. The parts cannot form a unified standard and have poor interchangeability. Summary of the invention

[0003] The present invention provides a modular heavy-duty impact bed, which adopts galvanized raw materials, modularized components, and standard parts manufacturing to improve the reliability, interchangeability and economy of the components, can realize standard parts assembly, does not require painting, rarely welds, is height-adjustable, saves materials, labor and time, reduces environmental pollution, can be manufactured using the same specification profiles and steel plates, realizes the versatility of raw materials, and reduces material reserves. The problems existing in existing impact beds are solved.

[0004] To achieve the above purpose, the present invention is implemented through the following technical scheme: it is composed of slot angle frame, slot angle plate, connecting plate, slot angle screw, slot angle screw, slot angle hole, base frame, base frame screw, beam, beam hole, cross beam, middle plate, middle plate screw, buffer strip mounting hole, cross beam long hole, cross beam vertical hole; buffer strip, buffer strip screw and other parts. The present invention first uses two unequal angle steels to make a beam, and the beam is drilled with a beam hole connected to the conveyor; then the two ends of the channel steel or other profiles are bent to make a cross beam, and the bent sections at both ends are drilled with long cross beam vertical holes for adjusting the center height of different roller diameters. The middle part of the plane on the cross beam is drilled with mounting holes for installing the middle plate and buffer strip, and the two sides are drilled with long cross beam holes for installing the slot angle bracket. Each buffer bed requires more than 2 beams. During installation, the main beams are set according to the distance of the conveyor frame, and the cross beams are separated according to the design requirements. The cross beams are adjusted to the design height according to different center heights, and connected to the main beams through frame screws or other bolt rivet structures to form the buffer bed frame. The middle plate can be arranged on the middle of the frame cross beam to strengthen the overall strength of the frame and enhance the impact resistance of the middle buffer strip. The middle plate is cut and formed by galvanized steel plate or other steel plate. The middle plate and the cross beam can be connected by middle plate screws or bolt rivets and other methods. The slot angle bracket is bent and formed by the slot angle plate, and the slot angle inclined surface is drilled with slot angle holes for installing the buffer strip. The bottom of the slot angle bracket is provided with a connecting plate, and the connection between the connecting plate and the slot angle plate can be connected by welding or other protective galvanizing methods; the slot angle bracket is installed on the long holes at both ends of the bottom frame cross beam through the bottom connecting plate and the slot angle screws and slot angle screws, and can be moved inside and outside to adjust the distance between the upper plane of the buffer strip and the bottom surface of the conveyor belt. The middle buffer strip is installed on the middle plate of the bottom frame through the buffer strip screws and buffer strip mounting holes. There are several buffer strips installed on the slot angle bracket and the middle plate. According to the needs, the trough angle bracket and the base frame of the present invention are all made of galvanized materials, and other materials can also be used. The above components can be made into standard parts. When in use, the cushion bed base frame is installed on the conveyor through the beam hole with screws.

[0005] The modular heavy-duty buffer bed consists of three major parts: a base frame, a slot angle bracket, and a buffer strip (also known as a buffer block). The base frame and the slot angle bracket form a frame to support the buffer strip to complete the function of the buffer bed. The buffer bed base frame is made of two unequal angle steels to form a beam, and is made of channel steel or other steel sections by bending and forming a crossbeam, which is connected by frame screws or other bolting and riveting measures. The slot angle bracket is bent and formed by steel plates, and slot angle holes are drilled on the slot angle inclined surface to install the buffer strip. The slot angle bracket is installed on the long holes at both ends of the base frame beam through the bottom connecting plate, and can be moved in and out to adjust the distance between the upper plane of the buffer strip and the bottom surface of the conveyor belt; the buffer strip is installed on the base frame middle plate and the slot angle surface of the slot angle bracket through the buffer bar screws. The frame of the present invention uses galvanized steel plate profiles or other steel plate profiles. Except for special requirements, the above components can be made into standard parts structure.

[0006] The beneficial effects of the present invention are as follows: 1. The frame components of each specification of the belt conveyor buffer bed are the same, which simplifies the process, reduces the material preparation, and realizes versatility and interchangeability; 2. The structure is simple and the frame is stable. All bolt-riveted structures are adopted, which greatly reduces the amount of welding, saves materials and labor, and greatly increases the impact resistance and safety. 3. Galvanized raw materials are used, and no painting is required, which reduces environmental pollution. 4. All specifications of the components are made of raw materials. Except for special requirements, they can be processed and manufactured with the same specifications of profiles and steel plates, which realizes the versatility of raw materials and reduces material reserves.
