Description

Technical Field

[0001] This utility model belongs to the field of wear-resistant plates and relates to a fixing structure for wear-resistant plates in the coal hopper of a coal loading car. Background Technology

[0002] Coal loading cars are devices used in the coking process to transfer and add coal to the coke oven. To prevent the coal from impacting and abrading the inner wall of the coal hopper, wear-resistant plates are installed on the inner wall of the coal hopper.

[0003] Currently, wear-resistant plates are generally fixed using bolts, welding, riveting, or mounting slots. Areas in the coal hopper are frequently subjected to coal impact and wear; therefore, wear-resistant plates in these areas require frequent replacement. Bolts or mounting slots are typically used for this purpose, allowing for convenient and quick replacement.

[0004] However, bolt fixing is complicated by the cumbersome operation process, requiring technicians to disassemble and install a large number of bolts, which results in a long replacement time for wear-resistant plates. The entire coking process needs to be stopped to wait for the wear-resistant plates of the coal loading cars to be replaced.

[0005] Replacing the mounting slot is relatively convenient, but it requires slotting the wear-resistant plate or coal hopper. In areas with significant coal impact, this can easily cause the wear-resistant plate to break or the coal hopper wall to crack. Utility Model Content

[0006] To overcome the shortcomings of the aforementioned related technologies, this utility model proposes a coal hopper wear-resistant plate fixing structure for a coal loading car, which features fast disassembly speed and strong impact resistance and wear resistance of the wear-resistant plate.

[0007] To achieve the above technical objectives, this utility model provides a coal hopper wear-resistant plate fixing structure for a coal loading car. The coal hopper wear-resistant plate fixing structure includes: fixing rods and fixing clips. Multiple fixing rods are fixed to the side of the wear-resistant plate that adheres to the inner wall of the coal hopper. Multiple through holes are provided at corresponding positions on the coal hopper. When the wear-resistant plate adheres to the inner wall of the coal hopper, each fixing rod passes through a corresponding through hole. A fixing clip is provided on each fixing rod located on the outer side of the coal hopper, and the fixing clip is used to fix the wear-resistant plate to the coal hopper.

[0008] Preferably, the fixing rod includes a straight rod and an annular groove disposed on the side wall of the straight rod, wherein when the fixing rod passes through the through hole, the annular groove is located outside the coal hopper. The fixing clip holds the straight rod tightly through the annular groove.

[0009] Preferably, the fixing clip includes: a fixing base, ball bearings, a sleeve, a housing, and a compression spring. The fixing base includes a straight tube and an outer tube. The straight tube is a pipe fitting, and its wall has multiple ball bearing holes. The inner diameters at both ends of the ball bearing holes are smaller than the inner diameter at the center of the ball bearing holes. An outer tube is coaxially fixed to the outside of the straight tube. The outer tube is also a pipe fitting, and its inner wall has internal threads. The ball bearings are disposed within the ball bearing holes. The diameter of the ball bearings is larger than the inner diameters at both ends of the ball bearing holes and larger than the inner diameter at the center of the ball bearing holes. The diameter of the ball bearings is larger than the wall thickness of the straight tube. When the ball bearings protrude to the inside or outside of the straight tube, they remain flush with the opposite side of the straight tube. The sleeve is a reducing pipe. The minimum inner diameter of the sleeve is clearance-fitted with the outer diameter of the straight tube. The outer diameter of the sleeve is smaller than the inner diameter of the outer tube. The sleeve is movably fitted onto the straight tube, and the end of the sleeve with the larger inner diameter is close to the coal hopper. The outer casing is a tubular fitting with one open end. The open end of the outer casing is provided with an external thread, and the inner diameter of the outer casing is clearance-fitted with the outer diameter of the sleeve. The outer casing is screwed to the inside of the outer tube. A compression spring is provided between the sleeve and the outer casing. Under the action of the compression spring, the sleeve moves closer to the coal hopper, and the inner wall of the smaller inner diameter section of the sleeve fits against the ball bearing hole.

[0010] Preferably, several of the multiple through holes form a through hole group, and each through hole group corresponds to the installation of a wear-resistant plate.

[0011] The wear-resistant plate fixing structure of the coal hopper of the coal loading car also includes a strong magnetic support, which comprises a support, electromagnets, and a power supply. The support is a square frame structure. Several electromagnets are fixed on the support, and the number and position of the electromagnets correspond to the number and position of the through holes in the through hole group. The power supply is fixed on the support and is electrically connected to the electromagnets. A switch is installed on the main output line of the power supply.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model uses fixing rods and fixing clips. During installation, it is only necessary to insert multiple fixing rods on the wear-resistant plate into the corresponding through holes and install the fixing clips on the corresponding fixing rods, which can realize the quick installation of the wear-resistant plate on the coal hopper.

[0014] When it is necessary to disassemble the wear-resistant plate, attach the strong magnetic bracket to the outside of the coal hopper, that is, attach each electromagnet to a corresponding fixing clip, turn on the switch to make the electromagnet acquire a strong magnet, and the strong magnet attracts the sleeve away from the coal hopper. At this time, the large inner diameter section of the sleeve is at the ball hole. Simply remove the strong magnetic bracket to allow the electromagnet to attract the fixing clip and detach it from the fixing rod, thus completing the disassembly of the wear-resistant plate.

[0015] This invention has the advantages of quick disassembly and installation, making it suitable for use in wear-resistant plates that require frequent replacement. Attached Figure Description

[0022] like Figure 1 and Figure 2As shown, this utility model provides a fixing structure for the wear-resistant plate of a coal hopper in a coal loading car. The fixing structure includes: fixing rods 1 and fixing clips 2. Multiple fixing rods 1 are fixed to one side of the wear-resistant plate 3 that adheres to the inner wall of the coal hopper 4. Multiple through holes are provided at corresponding positions on the coal hopper 4. When the wear-resistant plate 3 adheres to the inner wall of the coal hopper 4, each fixing rod 1 passes through a corresponding through hole. A fixing clip 2 is provided on each fixing rod 1 located on the outer side of the coal hopper 4. The fixing clip 2 is used to fix the wear-resistant plate 3 to the coal hopper 4.

[0023] The fixing rod 1 includes a straight rod and an annular groove disposed on the side wall of the straight rod. When the fixing rod 1 passes through the through hole, the annular groove is located outside the coal hopper 4. The fixing clip 2 holds the straight rod tightly through the annular groove.

[0024] The fixing clip 2 includes: a fixing base 21, ball bearings 22, a sleeve 23, a housing 24, and a compression spring 25. The fixing base 21 includes a straight tube 211 and an outer tube 212. The straight tube 211 is a pipe fitting, and multiple ball bearing holes 22 are provided on the tube wall of the straight tube 211. The inner diameters at both ends of the ball bearing holes 22 are smaller than the inner diameter at the middle of the ball bearing holes 22. The outer tube 212 is coaxially fixed to the outside of the straight tube 211. The outer tube 212 is a pipe fitting, and its inner wall is provided with internal threads. The ball bearings 22 are disposed in the ball bearing holes 22. The diameter of the ball bearings 22 is larger than the inner diameters at both ends of the ball bearing holes 22 and larger than the inner diameter at the middle of the ball bearing holes 22. The diameter of the ball bearings 22 is larger than the wall thickness of the straight tube 211. When the ball bearings 22 protrude to the inside or outside of the straight tube 211, the opposite side of the ball bearings 22 remains flush with the straight tube 211. The sleeve 23 is a reducing pipe. The minimum inner diameter of the sleeve 23 is clearance-fitted with the outer diameter of the straight pipe 211. The outer diameter of the sleeve 23 is smaller than the inner diameter of the outer pipe 212. The sleeve 23 is movably fitted onto the straight pipe 211, and the end of the sleeve 23 with the larger inner diameter is close to the coal hopper 4. The outer shell 24 is a pipe fitting with one open end. The open end of the outer shell 24 is provided with external threads, and the inner diameter of the outer shell 24 is clearance-fitted with the outer diameter of the sleeve 23. The outer shell 24 is screwed to the inside of the outer pipe 212. A compression spring 25 is provided between the sleeve 23 and the outer shell 24. Under the action of the compression spring 25, the sleeve 23 moves closer to the coal hopper 4, and the inner wall of the smaller inner diameter section of the sleeve 23 fits against the hole of the ball bearing 22.

[0025] Several of the through holes constitute a through hole group, and each through hole group corresponds to the installation of a wear-resistant plate 3.

[0026] The wear-resistant plate fixing structure of the coal hopper of the coal loading car also includes a strong magnetic support, which comprises a support, electromagnets, and a power supply. The support is a square frame structure. Several electromagnets are fixed on the support, and the number and position of the electromagnets correspond to the number and position of the through holes in the through hole group. The power supply is fixed on the support and is electrically connected to the electromagnets. A switch is installed on the main output line of the power supply.

[0027] It should be added that, to avoid deformation of the fixing rod 1 due to impact, the number of fixing rods 1 can be increased, for example, the number of fixing rods 1 on each wear-resistant plate 3 can be doubled compared to the previous bolt structure. At the same time, to prevent cracking of the through holes on the coal hopper 4, a reinforcing steel plate can be welded to the outside of the coal hopper 4 with the through holes, and the holes can be made at the corresponding positions on the reinforcing steel plate.

[0028] The distance between the annular groove on the fixing rod 1 and the wear-resistant plate 3 should be less than 0.1mm to ensure that the wear-resistant plate 3 is relatively flat after splicing.

[0029] The specific operation process of this utility model is as follows:

[0030] This utility model requires two people to work together. One technician attaches the wear-resistant plate to the inner wall of the coal hopper inside the coal loading car, and at the same time inserts multiple fixing rods into the through holes one by one; the other technician inserts the fixing clips into the fixing rods one by one outside the coal loading car to ensure that the balls fall into the annular groove.

[0031] When disassembly is required, one technician attaches the strong magnetic bracket to the outer wall of the coal hopper from the outside of the coal loading car, simultaneously attaching multiple electromagnets to their corresponding fixing clips. The switch is then turned on, and the strong magnetic adsorption sleeve moves away from the coal hopper. The technician can then remove the strong magnetic bracket to separate the fixing clips from the coal hopper. Another technician inside the coal loading car removes and replaces the wear-resistant plate. The technician outside the coal hopper can then reattach the strong magnetic bracket to the hopper, and the multiple fixing clips are directly inserted into their corresponding fixing rods. The switch is then turned off and on again, the electromagnets lose their force, and the strong magnetic bracket can be removed.

[0032] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
