Description

Technical Field

[0001] The present invention relates to the field of conveyor belts, and particularly to a belt bed capable of quickly replacing a conveyor belt. Background Art

[0002] A conveyor belt, also known as a transport belt, is a rubber, fiber, and metal composite product or a plastic and fabric composite product used to carry and transport materials in a conveyor belt. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemical engineering, and steel for occasions with short conveying distances and small conveying volumes. A color sorter is a device that automatically sorts out different-colored particles in granular materials based on the differences in the optical properties of the materials using photoelectric detection technology. Color sorters are used in the fields of bulk material or packaged industrial product and food quality inspection and grading. The conveyor belt of a crawler color sorter is a wearing part and needs to be replaced after being used for a certain period of time. However, the existing conveyor belts are relatively bulky and lack labor-saving devices, resulting in time-consuming and laborious replacement, delaying production, and causing economic losses. The reasons for the time-consuming and laborious replacement of the conveyor belt are as follows. There are supports on both sides of the conveyor belt, and the supports prop up the conveyor belt bracket. When replacing the conveyor belt, the support on one side of the conveyor belt must be removed so that the old conveyor belt can be taken out. At this time, a person has to hold up the conveyor belt bracket. Then, a person needs to bring the new conveyor belt over and put it on the front and rear shafts. Generally, 3 people are required to operate together. Summary of the Invention

A threaded hole is provided on the base 13. The threaded hole is threadedly connected to a threaded rod 14. The threaded rod 14 is connected to the installation block 12 through a bearing. The distance between the base 13 and the installation block 12 can be adjusted by rotating the threaded rod 14.

[0036] As Figure 4 、 5, as shown in Figures 6, the belt bed further includes a lifting mechanism for lifting the intermediate support frame 6. The lifting mechanism includes a base 15, a mounting frame 16, a rotating shaft 17, a runner 18, a steel wire rope 19, and a ratchet wheel 29. The base 15 is arranged below the intermediate support frame 6. The base 15 includes two symmetrically arranged vertical rods 1501. Two cross rods 1502 are fixedly arranged in parallel between the two vertical rods 1501. On one side of the upper ends of the two vertical rods 1501, brackets 1503 are respectively fixed. One end of the intermediate support frame 6 is fixed to the bracket 1503 on the base 15 through a fixing screw 20, and the other end of the intermediate support frame 6 is hinged to the other side of the upper ends of the two vertical rods 1501 on the base 15. One end of each of the two vertical rods 1501 is fixed to the mounting frame 16, and the mounting frame 16 is fixed to one end of the base 15 away from the fixing screw 20 and is located between the driving shaft 1 and the driven shaft 2. There are two rotating shafts 17. One end of each rotating shaft 17 is connected to a mounting seat 21 through a bearing, and the two mounting seats 21 are both fixed on the mounting frame 16. The other ends of the two rotating shafts 17 are fixed through a coupling 22. Runner 18 is fixedly sleeved outside the rotating shaft 17. One end of the steel wire rope 19 is fixed to one end of the intermediate support frame 6 away from the mounting frame 16. Hooks for fixing the steel wire rope 19 are respectively fixed on the intermediate support frame 6. The other end of the steel wire rope 19 is used for winding and fixing on the runner 18. Lugs can be arranged on the runner 18 for fixing the steel wire rope 19. Ratchet wheels 29 are respectively sleeved and fixed on the rotating shafts 17. A pawl 23 is hinged on the mounting frame 16, and the pawl 23 is meshed and connected with the ratchet wheel 29. A crank 24 is respectively installed on the rotating shaft 17, and the crank 24 is used for driving the rotating shaft 17 to rotate.

[0037] As Figure 9 shown, the belt bed further includes a conical limiter 25. The conical limiter 25 is in the shape of a frustum of a cone, and a through hole 26 is provided in the middle of the conical limiter 25. L-shaped mounting plates 27 are respectively fixed on both side ends of the intermediate support frame 6. A connecting rod 28 is fixed on the L-shaped mounting plate 27. The connecting rod 28 passes through the conical limiter 25, and the conical limiter 25 is connected to the connecting rod 28 through a bearing. The position of the conical limiter 25 on the connecting rod 28 is adjustable, so as to facilitate adjusting the position of the conical limiter 25. The part of the conveyor belt 3 located at the upper end of the intermediate support frame 6 is the running conveyor belt 302, and the part of the conveyor belt 3 located at the lower end of the intermediate support frame 6 is the return conveyor belt 301. The smaller-diameter end of the conical limiter 25 extends into the space between the running conveyor belt 302 and the return conveyor belt 301. The outer periphery of the conical limiter 25 contacts the upper end of the return conveyor belt 301. Multiple conical limiters 25 can be arranged to limit the movement of the conveyor belt 3.

[0038] Working principle: When the belt needs to be replaced, loosen the stop screw 9, and the slider 8 is no longer fixed to the slide rail 7, making the slider 8 approach the middle part of the middle support frame 6. The slider 8 drives the adjustment plate 4, the driving shaft 1, and the driven shaft 2 to approach the middle support frame 6, then the driving shaft 1 and the driven shaft 2 no longer tighten the conveyor belt 3, and the conveyor belt 3 is loosened. Take out one end of the steel wire rope 19 wound around the middle support frame 6, wind and fix the steel wire rope 19 on the rotating wheel 18, and remove the fixing screw 20 on the middle support frame 6, then one end of the middle support frame 6 is no longer fixed to the base 15. Then rotate the crank 24, the crank 24 drives the rotating shaft 17 to rotate, the rotating shaft 17 drives the rotating wheel 18 and the ratchet 29 to rotate, the rotating wheel 18 tightens the steel wire rope 19, making the steel wire rope 19 wind on the rotating wheel 18, and the steel wire rope 19 drives one end of the middle support frame 6 to lift. When the middle support frame 6 is lifted to a certain height, stop rotating the crank 24, the ratchet 29 stops rotating, the pawl 23 catches the ratchet 29, and the ratchet 29 and the rotating wheel 18 can no longer rotate, the steel wire rope 19 is tightened, and the staff can quickly draw out the conveyor belt 3 and replace it with a new one. After the conveyor belt 3 is replaced, rotate the crank 24 to reset the middle support frame 6, loosen the steel wire rope 19 on the rotating wheel 18, tighten the fixing screw 20, then reset the slider 8, and tighten the stop screw 9. The slider 8 drives the driving shaft 1 and the driven shaft 2 to tighten the conveyor belt 3. During the return process of the conveyor belt 3, due to the setting of the conical limiter 25, the conveyor belt 3 can be prevented from running off track and being damaged.
