Description

Technical Field

[0001] The invention belongs to the technical field of mine container guiding devices, and particularly relates to a roller cage ear which is convenient for disassembly and installation. Background Technique

[0002] The roller cage ear is an important part of a mine container (cage or skip or balance weight), playing a guiding and buffering role, and is a key component to ensure the smooth operation of the container (cage or skip or balance weight) along the guide rail. The traditional roller cage ear is composed of components such as a cantilever swing type support frame, a buffer, rollers installed on the support frame, a bottom plate, etc., and is divided into a symmetric type and an eccentric type.

[0003] In the existing roller cage ears, because a swing type support frame is adopted, during the operation of the container (cage or skip or balance weight), the force state of the rollers is unstable. Especially for the eccentric roller cage ear, the rollers not only bear the reverse thrust of the guide rail, but also bear the eccentric moment, and the rollers and the bearings and shafts inside them are more prone to wear, and the effective service life is limited. If the rollers are worn excessively, they need to be replaced. Among them, the traditional roller cage ear is restricted by its structure and cannot quickly disassemble and install the rollers. Therefore, we propose a roller cage ear which is convenient for disassembly and installation to solve the problems encountered above. Summary of the Invention

Detailed implementation manners

[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 10 As shown in the figure, a roller cage ear and a roller cage ear convenient for disassembly and installation include a bottom plate 1. A buffer structure is provided on the bottom plate 1. The buffer structure includes a mounting plate 2, a mounting frame 3, a mounting shell 5, a roller 9 and a buffer 10. The mounting plate 2 is connected to the surface of the bottom plate 1. The mounting frame 3 is hinged to the surface of the bottom plate 1 through a hinge member. A roller 9 is provided on the mounting frame 3. The mounting shell 5 is fixedly connected to the mounting frame 3. A buffer 10 is provided between the mounting shell 5 and the mounting plate 2.

[0030] In this application, the buffer 10 includes a cylinder body 100, a connecting rod 101, an elastic member 102 and a mounting member 103. The connecting rod 101 is slidably connected to the cylinder body 100. An elastic member 102 is sleeved on the surface of the connecting rod 101. A limiting ring is fixedly connected to the surface of the connecting rod 101. One side of the limiting ring is fixedly connected to one end of the elastic member 102. An installation hole is opened at one end of the connecting rod 101. A mounting member 103 is connected in the installation hole. The mounting member 103 is used in cooperation with the installation hole.

[0031] It should be noted that the reserved hole 8 is provided on the mounting shell 5 and is used in cooperation with the mounting member 103. The mounting hole is adapted to the mounting member 103. The mounting member 103 is a bolt, a screw, etc., but is not limited thereto. Other mounting elements can be used in this case. The elastic member 102 is a spring, an elastic rubber, etc., but is not limited thereto. Other elastic elements can be used in this case. When the guide rail exerts pressure on the roller 9, the elastic member 102 in the buffer 10 is oppressed by the pressure to generate elastic deformation, so that the mounting bracket 3 swings around the pin shaft, so that the guide block 6 on the mounting bracket 3 can drive the roller 9 to move along the slideway 7. The guide block 6 cooperates with the slideway 7 to prevent the roller 9 on the mounting bracket 3 from deviating, effectively ensuring the stability of the roller 9 during use.

[0032] In the present application, the mounting plate 2 includes a fixing plate 201 and a top plate 203. The fixing plate 201 is connected to the surface of the bottom plate 1, and the top plate 203 is fixedly connected to the top of the fixing plate 201; the bottom of the top plate 203 is fixedly connected to the slideway 7, and the top of the mounting bracket 3 is fixedly connected to the guide block 6, and the guide block 6 is used in cooperation with the slideway 7.

[0033] It should be noted that when the guide rail exerts pressure on the roller 9, the mounting bracket 3 swings around the pin shaft, so that the guide block 6 on the mounting bracket 3 can drive the roller 9 to move along the slideway 7. The guide block 6 cooperates with the slideway 7 to prevent the roller 9 from deviating and improve the stability of the roller 9 during use.

[0034] In the present application, the roller 9 includes a hub 91, a rubber wheel 92, a bearing 93 and a connecting shaft 94; a rubber wheel 92 is arranged on the surface of the hub 91, a mounting groove is formed in the hub 91, a bearing 93 is fixedly connected in the mounting groove, and a connecting shaft 94 is fixedly connected to the inner wall of the bearing 93; shaft holes 4 are formed on both sides of the mounting bracket 3, and both ends of the connecting shaft 94 are used in cooperation with the two shaft holes 4 respectively.

[0035] It should be noted that positioning rings for limiting the use of the rubber wheel 92 are arranged on both sides of the hub 91. When assembling the roller 9, the rubber wheel 92 is first sleeved on the outer wall of the hub 91, and then the two positioning rings are respectively fixed on both sides of the hub 91 by screws, which play a role in limiting the rubber wheel 92. And thread glue is applied to the screws to prevent the rubber wheel 92 from falling off caused by the positioning rings. And the bearing 93 is filled with base grease to fill one-third of the space of the bearing 93 and the bearing housing, so that the bearing 93 is in the best state and ensures the normal use of the bearing 93.

[0036] In the present application, including a roller guide ear according to any one of the above, a disassembly and assembly plate 202 is arranged on the mounting plate 2, the mounting bracket 3 is fixedly connected with a side plate 12 through a connecting piece, and a disassembly and assembly structure is arranged on the side plate 12.

[0037] It should be noted that the disassembly and assembly structure is used for disassembling and assembling the roller 9, and both the disassembly and assembly plate 202 and the side plate 12 are detachable.

[0038] In the present application, the disassembly and assembly structure includes a fixing groove 13, a compression spring 14, a baffle 15 and a movable plate 16; a fixing groove 13 is formed on one side of the side plate 12, and compression springs 14 are fixedly connected to both the top and bottom of the fixing groove 13. One end of the compression spring 14 is fixedly connected to a baffle 15. Notches are formed on the sides of the two baffles 15 close to each other. A movable plate 16 is fixedly connected to one side of the baffle 15, and the movable plate 16 is slidably connected to one side of the side plate 12.

[0039] It should be noted that one end of the movable plate 16 has a block for dragging. The notch is composed of a straight surface and a curved surface, and half of the shaft hole 4 is formed by two symmetrical notches. During use, the block is dragged to make the movable plate 16 drive the two baffles 15 to move away from each other and compress the compression spring 14, so that a gap large enough for the shaft diameter of the connecting shaft 94 is exposed between the two baffles 15, and the limitation on the connecting shaft 94 can be released, and the roller 9 with excessive wear can be taken out. Subsequently, after the connecting shaft 94 of the new roller 9 is placed in the shaft hole 4 and the block is released, under the elastic force of the compression spring 14, the notches on the two baffles 15 are closely attached to each other and cooperate with the shaft hole 4 to play a role in limiting the connecting shaft 94, thereby completing the installation of the roller 9.

[0040] In the present application, the disassembly and assembly structure further includes a second socket 17, a first socket 18, a fixing cavity 19, a limiting spring 20, a sliding plate 21, a second insertion block 22 and a first insertion block 23; the movable plate 16 is respectively provided with a first socket 18 and a second socket 17, and a fixing cavity 19 is formed on the side plate 12. Limiting springs 20 are symmetrically and fixedly connected to the inner wall of the fixing cavity 19. One end of the limiting spring 20 is fixedly connected to a sliding plate 21, and a first insertion block 23 and a second insertion block 22 are respectively fixedly connected to one side of the sliding plate 21. The first insertion block 23 and the second insertion block 22 are both used in cooperation with the first socket 18 and the second socket 17.

[0041] It should be noted that the surface of the slide plate 21 is connected with an operating plate for movement. When in use, the operating plate is moved to move the slide plate 21 and compress the limit spring 20, so that the first plug block 23 and the second plug block 22 are received in the fixed cavity 19, and the stopper is dragged to move the movable plate 16 until the first plug block 23 and the second socket 17 are aligned and the second plug block 22 and the first socket 18 are aligned. Then, the operating plate is released, and the first plug block 23 and the second plug block 22 are inserted into the corresponding first socket 18 and the second socket 17 under the elastic force of the limit spring 20, so that the baffle 16 is moved. 5. After the limit is completed, there is no need to continuously drag the stopper to apply force, which is convenient for installing the roller 9. After the roller 9 is installed, the operating panel is toggled to move the slide plate 21 and compress the limit spring 20, so that the first plug block 23 and the second plug block 22 are received in the fixed cavity 19, and the restriction on the movable plate 16 is released until the two baffles 15 return to the initial position. Then, the operating panel is released, and under the action of the limit spring 20, the first plug block 23 is inserted into the first socket 18, thereby positioning the baffle 15 on the movable plate 16 and ensuring the stability of the roller 9.

[0042] In the present application, the first plug-in block 23 and the second plug-in block 22 are both right-angled trapezoidal blocks, and the first plug-in block 23 and the second plug-in block 22 are symmetrically arranged.

[0043] Since the first plug block 23 and the second plug block 22 are both right-angled trapezoidal blocks, the moving block makes the straight surface of the movable plate 16 touch and squeeze the inclined surface of the first plug block 23, which will drive the first plug block 23 and the second plug block 22 to be synchronously squeezed into the fixed cavity 19 through the slide plate 21.

[0044] When the present invention is specifically implemented:

[0045] When the present invention is in use, the tank channel applies pressure to the roller 9, and the elastic member 102 in the buffer 10 is compressed by the pressure to produce elastic deformation, so that the mounting frame 3 swings with the pin as the axis. The setting of the reserved hole 8 can satisfy the swing of the buffer 10, so that the guide block 6 on the mounting frame 3 can move along the slideway 7 with the roller 9. When the pressure applied by the tank channel to the roller 9 is reduced, the elastic member 102 in the buffer 10 expands and releases the elastic force, so that the positions of the roller 9 and the mounting frame 3 change with the change of the applied pressure. In the state without pressure, the roller 9 and the mounting frame 3 return to the initial position, and the buffer structure composed of the base plate 1, the mounting plate 2, the mounting frame 3 and the buffer 10 can bear the force with one buffer 10 to play the role of upper buffer or lower buffer, thereby improving the stress state of the bearing 93 and making the displacement change of the roller 9 tend to be linear, reducing the torsional moment and eccentric moment of the roller 9, and compared with the existing roller ear structure, making the force on the roller 9 more uniform, reducing the wear of the rubber wheel 92 on the roller 9, and reducing the deformation range of the elastic member 102, thereby extending the service life of the roller 9.

[0046] When the wear amount of the roller 9 exceeds a certain level, the disassembly and installation plate 202 and the side plate 12 can be successively removed, the worn roller 9 can be taken out, and a new roller 9 can be replaced. After installation and debugging, it can be used continuously. Or the stopper is moved to drive the movable plate 16 to move, so that the first insertion block 23 is squeezed against the first socket 18, and the first insertion block 23 drives the second insertion block 22 to retract into the fixed cavity 19 through the sliding plate 21 until, under the action of the limiting spring 20, the first insertion block 23 is inserted into the second socket 17 and the second insertion block 22 is inserted into the first socket 18 to complete the limiting of the baffle 15. Then the roller 9 can be taken out for replacement. After replacement, the operating plate is moved, and under the action of the compression spring 14, the baffle 15 returns to its initial position to complete the installation of the roller 9. And under the action of the limiting spring 20, the first insertion block 23 is inserted into the first socket 18 to limit the movable plate 16 and ensure the stability of the roller 9 after installation. Through the cooperation of the compression spring 14, the baffle 15, the movable plate 16, the first socket 18, the second socket 17, the limiting spring 20, the sliding plate 21, the first insertion block 23, and the second insertion block 22, moving the movable plate 16 can facilitate the quick disassembly and assembly of the roller 9. Moreover, the structure is simple and easy to use, effectively improving the disassembly and assembly efficiency of the roller 9.
