Description

Technical Field

[0001] This invention belongs to the technical field of rock wool production equipment, and particularly relates to a centrifuge disassembly and assembly device and its usage method. Background Technology

[0002] Four-roller centrifuges are one of the main pieces of equipment for producing rock wool products. For centrifuges, bearings are important motor transmission components, as their quality directly affects the lifespan of the centrifuge's transmission components.

[0003] The bearing is mounted on the main shaft. If the bearing is damaged during use, the operator needs to pull the entire main shaft out of the centrifuge bearing housing and then remove the bearing from the main shaft.

[0004] When replacing bearings in a centrifuge, since there is no dedicated disassembly and assembly equipment, it is traditionally necessary for four to five operators to work together to disassemble and assemble the centrifuge shaft and bearings. Sometimes, in order to save time, workers may resort to violent disassembly and assembly methods such as using hammers to strike the bearings, which is time-consuming, labor-intensive, and can easily damage the main shaft and bearings. Summary of the Invention

[0005] To address the deficiencies or shortcomings in existing technologies, this invention provides a centrifuge disassembly and assembly device and its usage method, which can quickly replace the centrifuge spindle and spindle bearings, avoiding damage to the centrifuge spindle and bearings caused by violent disassembly and assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, embodiments of the present invention provide a centrifuge disassembly and assembly device, including a support platform. The support platform is provided with a disassembly and assembly shaft bracket and a disassembly and assembly bearing bracket.

Multiple second positioning grooves are provided on both second side plates, and the multiple second positioning grooves on the two second side plates are correspondingly arranged. Multiple second positioning holes are also provided on the second support plate, and the multiple second positioning holes correspond one-to-one with the multiple second positioning grooves.

[0008] Furthermore, an oil collection box is provided at the bottom of the support platform. The oil collection box has an inverted conical structure with an opening at the top.

[0009] Furthermore, the mounting and dismounting shaft bracket also includes a shaft mounting end, and the shaft mounting end and the shaft unmounting end are symmetrically arranged.

[0010] Furthermore, the mounting end includes a first support plate, and a first side plate is provided at the end of the first support plate away from the unmounting end. There are two first side plates, which are symmetrically arranged.

[0011] Furthermore, the first side plate is provided with a plurality of first positioning grooves, and the plurality of first positioning grooves on the two first side plates are correspondingly arranged. The first support plate is provided with a plurality of first positioning holes, and the first positioning holes correspond one-to-one with the plurality of first positioning grooves on the first side plate.

[0012] Furthermore, it also includes a baffle, which has a T-shaped structure and is placed between the two side plates.

[0013] Furthermore, the bearing bracket includes a bearing mounting end and a bearing unmounting end, which are arranged opposite to each other.

[0014] Furthermore, the bearing mounting end includes a base plate, which is fixed to the upper surface of the support platform. A tail plate is provided at the end of the base plate away from the bearing unmounting end. The tail plate is perpendicular to the base plate. Connecting plates are also provided on both sides of the base plate. The connecting plates are used to connect and fix the base plate and the tail plate.

[0015] Furthermore, the bearing retraction end includes a U-shaped baffle and a bracket. The U-shaped baffle is disposed on the side of the bracket near the bearing mounting end. The cross-section of the bracket is U-shaped, and a U-shaped groove is formed on the U-shaped baffle.

[0016] Secondly, embodiments of the present invention provide a method for using a centrifuge disassembly and assembly device, comprising the following steps:

[0017] When disassembling the centrifuge main shaft, the centrifuge bearing housing to be disassembled is moved to the disassembly and assembly shaft bracket. The baffle is inserted into the shaft retraction end. The bearing housing is fixed with the second angle iron. The ejector end of the manual hydraulic pump is placed on the shaft retraction end. The manual hydraulic pump is pressed by hand to make the ejector end of the manual hydraulic pump eject the shaft.

[0018] When disassembling the centrifuge spindle bearing, first place the ejected shaft onto the bearing push end, place the ejector end of the manual hydraulic pump onto the bearing mounting end, and turn the shaft toward the bearing mounting end. Use a U-shaped baffle to block the bearing, allowing the manual hydraulic pump to eject the shaft and separate the shaft from the bearing. Repeat this operation to eject the other bearing. At this point, the shaft and bearing disassembly are complete.

[0019] When installing the centrifuge spindle bearing, put the new bearing on the shaft, put the ejector end of the manual hydraulic pump into the bearing mounting end, and align the shaft with the bearing mounting end. Use a U-shaped baffle to block the bearing, allowing the manual hydraulic pump to push the shaft in, making the shaft and bearing fit tightly together.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] A typical embodiment of the present invention, such as Figure 1 and Figure 2As shown, a centrifuge disassembly and assembly device includes a support platform 1. One end of the support platform 1 is provided with a disassembly and assembly shaft bracket, and the other end is provided with a disassembly and assembly bearing bracket. The disassembly and assembly shaft bracket and the disassembly and assembly bearing bracket are welded parallel to each other on the upper surface of the support platform 1. An oil collection box 2 is provided at the bottom of the support platform 1. The oil collection box 2 has an inverted conical structure and an opening at the top to facilitate the collection of lubricating oil during the disassembly and assembly process.

[0030] The assembly and disassembly shaft bracket includes a shaft mounting end 3 and a shaft retraction end 4, which are symmetrically arranged. The shaft mounting end 3 includes a first support plate 31. A first side plate 32 is provided at the end of the first support plate 31 away from the shaft retraction end 4. There are two first side plates 32, which are symmetrically arranged. Multiple first positioning grooves 33 are provided on the first side plates 32, and the multiple first positioning grooves 33 on the two first side plates 32 are correspondingly arranged. Multiple first positioning holes 34 are provided on the first support plate 31, and the first positioning holes 34 correspond one-to-one with the multiple first positioning grooves 33 on the first side plates 32.

[0031] Multiple first angle irons 35 are provided at the end of the first support plate 31 away from the first side plate 32. The cross-section of the first angle iron 35 is triangular. There are two first angle irons 35, which are symmetrically arranged. By placing the bearing housing on the two first angle irons 35, the bearing housing is fixed by the first angle irons 35 during shaft installation, thus preventing the bearing housing from moving.

[0032] The retractable shaft end 4 includes a second support plate 41, and second side plates 42 are provided on both sides of the second support plate 41. Multiple second positioning grooves 43 are provided on both second side plates 42, and the multiple second positioning grooves 43 on the two second side plates 42 are correspondingly provided. Multiple second positioning holes 44 are also provided on the second support plate 41, and the multiple second positioning holes 44 correspond one-to-one with the multiple second positioning grooves 43.

[0033] The second support plate 41 is provided with a plurality of second angle irons 45 at the end away from the second side plate 42. The cross section of the second angle iron 45 is triangular. There are two second angle irons 45, which are symmetrically arranged. By placing the bearing housing on the two second angle irons 45, the bearing housing is fixed by the second angle irons 45 when the shaft is removed, thus preventing the bearing housing from moving.

[0034] It also includes a baffle 5, which has a T-shaped structure. The baffle 5 can be placed between the two side plates. When the baffle 5 is placed between the two side plates, both ends of the baffle 5 are inserted into the positioning grooves of the two side plates, and the bottom of the baffle 5 is inserted into the positioning hole, thus fixing the baffle 5 between the two side plates. This allows the centrifuge spindle to be disassembled and assembled using the baffle 5. By inserting the baffle 5 into different positioning grooves, the centrifuge spindles of different sizes can be disassembled, which facilitates the use of the manual hydraulic pump and improves the applicability of the equipment.

[0035] The bearing bracket assembly and disassembly includes a bearing mounting end 6 and a bearing unmounting end 7, which are arranged opposite to each other. The bearing mounting end 6 includes a base plate 61, which is fixed to the upper surface of the support platform 1. A tail plate 62 is provided at the end of the base plate 61 away from the bearing unmounting end 7. The tail plate 62 is perpendicular to the base plate 61. Connecting plates 63 are also provided on both sides of the base plate 61. The connecting plates 63 connect and fix the base plate 61 and the tail plate 62 to strengthen the connection strength between the base plate 61 and the tail plate 62.

[0036] The bearing removal end 7 includes a U-shaped baffle 71 and a bracket 72. The U-shaped baffle 71 is located on the side of the bracket 72 near the bearing mounting end 6. The bracket 72 has a U-shaped cross-section, which can place and fix the centrifuge spindle. The U-shaped baffle 71 has a U-shaped groove, which allows the centrifuge spindle to pass through the U-shaped baffle 71, thereby using the U-shaped baffle 71 to disassemble and assemble the bearing.

[0037] Example 2

[0038] This embodiment provides a method for using a centrifuge disassembly and assembly device, which utilizes a centrifuge disassembly and assembly device as described in Embodiment 1, including the following steps:

[0039] When disassembling the centrifuge main shaft, move the centrifuge bearing housing to be disassembled between the angle irons at the shaft removal end on the disassembly and assembly shaft bracket. Place both ends of the bearing housing between the second angle irons on both sides to keep the bearing housing fixed. Insert the baffle into the shaft removal end, and place the ejector end of the manual hydraulic pump between the baffle and the shaft on the shaft removal end. When the manual hydraulic pump is pressed by hand, the ejector rod of the manual hydraulic pump ejects outward, giving the centrifuge shaft an outward thrust, thereby ejecting the shaft.

[0040] When disassembling the centrifuge spindle bearing, first place the ejected shaft on the bearing removal end of the bearing mounting bracket. Place the ejector end of the manual hydraulic pump between the tail plate on the bearing mounting end and the shaft. Orient the shaft toward the bearing mounting end so that the manual hydraulic pump ejects the shaft, giving the centrifuge shaft an outward thrust. The bearing is blocked by the U-shaped baffle and cannot move. The shaft moves outward, separating the shaft from the bearing. Repeat this operation to eject the other bearing. At this point, the shaft and bearing disassembly are complete.

[0041] When installing the centrifuge spindle bearing, put the new bearing on the shaft, insert the ejector end of the manual hydraulic pump into the bearing mounting end on the bearing mounting bracket, and the bearing fits against the inside of the U-shaped baffle. Turn the shaft toward the bearing mounting end, so that the manual hydraulic pump pushes the shaft in, giving the shaft an outward thrust. The shaft moves to one side of the U-shaped baffle, and the bearing is blocked and fixed by the U-shaped baffle, so that the shaft and the bearing fit tightly. Repeat this operation to push the other bearing.

[0042] When installing the centrifuge spindle, insert the bearing-equipped shaft into the bearing housing, place the bearing housing between the angle irons on the shaft mounting bracket, and place both ends of the bearing housing between the first angle irons on both sides to keep the bearing housing fixed. Insert the baffle into the shaft mounting end, place the ejector end of the manual hydraulic pump between the baffle and the shaft on the shaft mounting end, press the manual hydraulic pump by hand to push the ejector end of the manual hydraulic pump into the shaft, and move the shaft to one side of the bearing housing. The bearing housing remains fixed, and the shaft is retracted into the bearing housing, completing the shaft installation operation.
