Description

Technical Field

[0001] The present application relates to the technical field of belt conveyors, and in particular to a tail buffer beam structure of a belt conveyor moving machine. Background Art

[0002] At present, belt conveyor is the abbreviation of belt conveyor, which is available in fixed and mobile types, with simple structure and high efficiency. It is a continuous conveying machine with flexible conveyor belt as material carrying and traction component. The tail buffer beam of the belt conveyor mobile machine supports the buffer roller frame. The tail beam of the mobile machine for normal comprehensive excavation is installed with seven groups, each group is equipped with seven buffer roller frames, and the buffer roller frames and the tail buffer beam of the mobile machine are connected by welding angle iron overlap stitching. Since the second-carrying belt conveyor carriage of the comprehensive excavation machine moves back and forth on the mobile buffer beam runway as the comprehensive excavation machine is delivering goods head-on, the comprehensive excavation machine swings its butt forward and backward to deliver goods, and the second-carrying carriage is very likely to scrape the buffer roller frame, causing the connecting angle iron plate between the buffer roller frame and the buffer beam to deform or open the weld, resulting in the buffer roller frame having no rooting point and being unable to be reinstalled. The belt conveyor lacks buffer roller frames and is very likely to spill goods, affecting the delivery of the footage. Replacing the buffer beam is time-consuming and consumes a lot of material costs. Summary of the Invention

[0003] In order to make up for the above shortcomings, the present application provides a belt conveyor mobile tail buffer beam structure, which aims to improve the conventional comprehensive excavator second-carry belt conveyor carriage. As the comprehensive excavator is delivering goods head-on, it moves back and forth on the mobile buffer beam runway. The comprehensive excavator swings its butt forward and backward to deliver goods. The second-carry carriage is very likely to scrape the buffer roller frame, causing the connecting angle iron plate between the buffer roller frame and the buffer beam to deform or open, resulting in the buffer roller frame having no rooting point and being unable to be reinstalled. The belt conveyor lacks a buffer roller frame and is very likely to spill goods, affecting the advance delivery, and replacing the buffer beam is time-consuming and consumes a lot of material costs.

[0004] An embodiment of the present application provides a belt conveyor moving tail buffer beam structure, including a roller frame, an angle iron plate, a fixing mechanism and a clamping mechanism, wherein side panels are installed on the left and right sides of the roller frame, the angle iron plate is installed on the upper side of the roller frame, a fixing mechanism that is easy to disassemble is installed between the side panels and the angle iron plate, and a clamping mechanism for adjusting the size is installed on the left and right sides of the roller frame.

[0005] The second screw grooves on both sides of the angle iron plate are aligned with the first screw grooves on both sides of the side plate respectively, and the fixing bolts are twisted to engage in the first screw groove and the second screw groove and rotate downward to fix the side plate and the angle iron plate. The front and rear knobs are manually twisted to drive the screw to rotate. The screw rotation engages with the inner hole thread of the limit block through the outer wall thread. Under the limitation of the limit groove, the limit block slides vertically in the limit groove and moves toward the inner end, driving the upper clamping plate to move inward, clamping the angle iron plate from the front and back, so that the angle iron plate remains stable and level. When disassembly is required, the knob is twisted forward and backward to move the clamping plate outward and separate, and the fixing bolt is twisted upward to engage in the first screw groove and the second screw groove and remove it, and the angle iron plate can be directly disassembled and replaced upward.

[0006] In a specific embodiment, the fixing mechanism includes a first screw groove and a second screw groove, the first screw groove is opened on the left and right sides of the side plate, and the second screw groove is opened on the left and right sides of the angle iron plate, and fixing bolts are installed inside the first screw groove and the second screw groove.

[0007] In the above implementation process, efficient disassembly or installation operations are achieved by engaging and installing in the first screw groove and the second screw groove.

[0008] In a specific embodiment, the clamping mechanism includes a limit groove, which is opened on the left and right sides of the roller frame, a screw is installed inside the limit groove, a limit block is mounted on the outer wall of the screw, the front end of the screw passes through the limit groove and is connected to a knob, and a splint is installed on the upper end of the limit block.

[0009] In the above implementation process, the limiting block is engaged and moved while being limited by the limiting groove to move vertically forward and backward to effectively clamp and limit the diagonal iron plate.

[0010] In a specific embodiment, the position of the first screw groove corresponds to the position of the second screw groove.

[0011] In the above implementation process, more stable installation and fixed limitation are achieved through corresponding positions.

[0012] In a specific embodiment, the inner wall threads of the first screw groove and the second screw groove are engaged with the outer wall threads of the fixing bolt.

[0013] In the above implementation process, it is easier to install or disassemble by twisting.

[0014] In a specific embodiment, the shape and size of the limiting block match the shape and size of the limiting groove, and both are convex.

[0015] In the above implementation process, the clamping is made more stable by making the clamping plate more stable during movement.

[0016] In a specific embodiment, the outer wall thread of the screw and the inner hole thread of the limiting block are engaged with each other.

[0017] In the above implementation process, the relative engagement between the threads on the outer wall of the screw and the interior of the limit block makes it easier to move and adjust the position. BRIEF DESCRIPTION OF THE DRAWINGS
