Description

Technical field:

[0001] The utility model relates to the field of belt conveyor maintenance, in particular to a quick-detachable roller structure for a belt in a coal blending chamber. Background technology:

[0002] In coking production, a variety of raw materials are sent to the coal blending room for blending. Since a variety of raw materials are discharged from silos separately and there is wet material with high humidity in the raw materials, when the wet material falls onto the weighing skirt belt conveyor, it will cause external scattering. A small amount of it will adhere to the belt rollers of the belt conveyor, causing the belt rollers to rotate poorly. At the same time, the wet material will also stick to the belt, affecting the rotation relationship between the rollers and the belt, which will lead to inaccurate weighing of the weighing skirt belt conveyor and fluctuations in the indicators of the blended coal and single coal. Therefore, it is very important to design a quick-detachable roller structure that is easy to clean. Utility model content:

[0003] The utility model aims to provide a quick-detachable roller structure for a belt in a coal blending chamber.

[0004] The utility model is implemented by the following technical solutions:

[0005] A quick-detachable roller structure for a coal distribution chamber belt, comprising a belt support, and a plurality of pairs of "concave"-shaped side support plates, each pair of the side support plates being respectively fixed to the top of the belt support, a roller being arranged between the pair of the side support plates, and both ends of the roller being rotatably connected to an H-shaped slider;

[0006] The H-shaped slider is slidably inserted into the notch in the middle of the side support plate;

[0007] A pressure rod is provided on the top of the side support plate, one end of the pressure rod is bent downward and hinged to one side of the side support plate, the other end of the pressure rod extends out of the other side of the side support plate and is set to an inclined end face inclined upward, and a ring sleeve is hinged on the side edge of the side support plate below the inclined end face, and the ring sleeve is movably sleeved on the pressure rod;

[0008] A push rod is slidably inserted on the pressure rod, a shaped frame is fixed on the top of the pressure rod, a spring is fixed between the top end of the push rod and the shaped frame, and the bottom end of the push rod abuts against the H-shaped sliding block.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 5 As shown, a quick-detachable roller structure of a coal blending chamber belt includes a belt support 1 and a plurality of pairs of "concave"-shaped side support plates 2, each pair of side support plates 2 is respectively fixed to the top of the belt support 1, and a roller 3 is arranged between a pair of side support plates 2, and both ends of the roller 3 are rotatably connected to an H-shaped slider 4, and both ends of the roller 3 can be rotatably connected to the H-shaped slider 4 through bearings;

[0020] An H-shaped slider 4 is slidably inserted into the notch in the middle of the side support plate 2. The H-shaped slider 4 is in an "H" shape when viewed from above. The two sides of the H-shaped slider 4 just clamp the side walls of the notch in the middle of the side support plate 2, so that the two ends of the roller 3 will not move in the axial direction.

[0021] A pressure rod 5 is provided on the top of the side support plate 2, one end of the pressure rod 5 is bent downward and hinged with one side of the side support plate 2, and the other end of the pressure rod 5 extends out of the other side of the side support plate 2 and is set to an inclined end face 6 inclined upward. A ring sleeve 7 is hinged on the side of the side support plate 2 below the inclined end face 6, and the ring sleeve 7 is movably sleeved on the pressure rod 5, pushing the top of the ring sleeve 7 so that it can slide onto the pressure rod 5 more easily through the inclined end face 6, and the pressure rod 5 is pressed down to the notch in the middle of the side support plate 2 to prevent the H-shaped slider 4 from sliding upward and falling out. A notch 8 is provided on the pressure rod 5 on one side of the inclined end face 6, and the ring sleeve 7 can be sunk into the notch 8 on the pressure rod 5, thereby improving the stability of the ring sleeve 7 and preventing it from easily falling off from the pressure rod 5. The pressure rod 5 and the ring sleeve 7 are made of metal and have the toughness of restoring after deformation;

[0022] A push rod 9 is slidably inserted on the pressure rod 5, and a shaped frame 10 is fixed on the top of the pressure rod 5. A spring 11 is fixed between the top of the push rod 9 and the shaped frame 10. The bottom end of the push rod 9 abuts against the H-shaped slider 4. When the pressure rod 5 is blocked at the notch in the middle of the side support plate 2, the push rod 9 is acted upon by the elastic force of the spring 11 to push the H-shaped slider 4 downward, so that the H-shaped slider 4 is firmly fixed in the notch of the side support plate 2.

[0023] Working principle: When quickly disassembling the roller 3, push the top of the ring sleeve 7 out of the notch 8 of the pressure rod 5, so that the ring sleeve 7 rotates away from the pressure rod 5, and then rotates the pressure rod 5 to make it leave the notch of the side support plate 2, and slide the H-shaped sliders 4 at both ends of the roller 3 upward from the notch of the corresponding side support plate 2 to complete the quick disassembly of the roller 3.

[0024] The novel structure can remove the restriction of the ring sleeve 7 on the pressure rod 5, and then rotate the pressure rod 5 to release the restriction at the recess of the side support plate 2, so that the two ends of the roller 3 can be easily removed from the side support plate 2, and the disassembly can be completed quickly, which is conducive to the replacement and cleaning of the roller 3.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
