Abstract
Description
Technical Field
[0001] This utility model belongs to the field of conveyor technology, specifically relating to a replacement device for idler rollers of a mining belt conveyor. Background Technology
[0002] Idler rollers are important components of mining belt conveyors, used to support the weight of the conveyor belt and materials. During production in mines, idler rollers operate continuously for long periods, often resulting in surface wear and high frequency of bearing failure, necessitating frequent replacement of the rollers.
[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN223188845U discloses a belt lifting device for replacing idlers. It uses a lifting plate to contact the bottom of the belt, and then uses a lifting mechanism to lift the lifting plate to raise the belt, providing operating space for replacing idlers. The lifting plate is an integral structure that is adapted to a certain specification of belt support. When the belt width is smaller than the lifting plate, the belt is prone to slipping on the lifting plate during lifting, resulting in poor stability. When the belt width is larger than the lifting plate, the belt cannot enter the interior of the lifting plate, and the belt cannot be lifted.
[0004] Therefore, it is necessary to design a rolling stock replacement device for mining belt conveyors that can be adjusted and adapted to various belt specifications within a certain range and has a wide range of applications to solve the current technical problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a rolling idler replacement device for mining belt conveyors that can be adjusted and adapted to various belt specifications within a certain range and has a wide range of applications.
[0006] The technical solution of this utility model is as follows: a replacement device for idler rollers of a mining belt conveyor, including a horizontal support rod, on which a horizontal adjustment mechanism is symmetrically arranged; a side support rod and an angle adjustment mechanism are arranged at the top of the horizontal adjustment mechanism; and a lifting mechanism is movably arranged at both ends of the horizontal support rod; the horizontal adjustment mechanism has a support cylinder slidably fitted on the horizontal support rod, and the support cylinder is provided with a locking component for locking or releasing it from the horizontal support rod; one end of the side support rod is hinged to the top of the support cylinder, and the angle adjustment mechanism is used to adjust the angle of the side support rod.
[0007] Furthermore, the angle adjustment mechanism has an adjustment seat slidably disposed on the top of the support cylinder. The adjustment seat is internally threaded with a screw rod whose axial direction is consistent with its sliding direction. Both ends of the screw rod are rotatably mounted on the top of the support cylinder through supports. A connecting rod is hinged to the top of the adjustment seat, and one end of the connecting rod opposite to the adjustment seat is hinged to the bottom of the side support rod.
[0008] Furthermore, the adjusting seat has two guide rods slidably disposed inside, parallel to the screw, and the two ends of the guide rods are fixedly connected to the two supports.
[0009] Furthermore, a hexagonal prism is fixedly provided at one end of the screw.
[0010] Furthermore, the cross brace has evenly spaced adjustment holes, and the locking component is a bolt and nut mechanism located on the support cylinder corresponding to the adjustment holes.
[0011] Furthermore, the lifting mechanism has a jack body, the top of the jack body has a top seat, and the top of the top seat is fixedly provided with an installation sleeve, which is fitted onto the end of the cross brace.
[0012] Furthermore, the cross brace is provided with a limiting stop corresponding to the mounting sleeve.
[0013] Furthermore, the main body of the jack is a scissor jack.
[0014] The beneficial effects of this utility model are: (1) In this utility model, the distance between the two side support rods is adjusted by the horizontal adjustment mechanism, and the angle of the side support rods is adjusted by the angle adjustment mechanism so that the angle and spacing of the side support rods match the belt; (2) Stop the conveyor, pass the cross brace under the belt, and initially support the two ends of the cross brace through the lifting mechanism. Lift the cross brace upward through the lifting mechanism. The cross brace moves up and lifts the belt. After the belt and the idler are separated, the idler can be replaced. (3) The angle and spacing of the side support rods can be adjusted within a certain range, so as to adapt to the replacement of various specifications of belt conveyor rollers; (4) No electricity or hydraulic drive is required; the belt can be supported manually, which is convenient for on-site implementation.

Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0020] like Figures 1 to 3 As shown, a replacement device for idler rollers of a mining belt conveyor is disclosed, including a horizontal support rod 1, a horizontal adjustment mechanism 5 symmetrically arranged on the horizontal support rod 1, a side support rod 2 and an angle adjustment mechanism 4 arranged on the top of the horizontal adjustment mechanism 5, and a lifting mechanism 3 movably arranged at both ends of the horizontal support rod 1; the horizontal adjustment mechanism 5 has a support cylinder 52 slidably fitted on the horizontal support rod 1, and the support cylinder 52 is provided with a locking component for locking or releasing it between itself and the horizontal support rod 1; the bottom of one end of the side support rod 2 is hinged to the top of the support cylinder 52, and the angle adjustment mechanism 4 is used to adjust the angle of the side support rod 2.
[0021] During implementation, the distance between the two side support rods 2 is adjusted by the horizontal adjustment mechanism 5, and the angle of the side support rods 2 is adjusted by the angle adjustment mechanism 4 so that the angle and spacing of the side support rods 2 match the belt. The conveyor is stopped, and the cross support rod 1 is passed under the belt. The two ends of the cross support rod 1 are initially supported by the lifting mechanism 3. The lifting mechanism 3 lifts the cross support rod 1 upward, and the cross support rod 1 moves upward to lift the belt. After the belt and the idler are separated, the idler can be replaced.
[0022] In some embodiments, such as Figure 3As shown, the angle adjustment mechanism 4 has an adjustment seat 44 that is slidably disposed on the top of the support cylinder 52 along the extension direction of the support cylinder 52. The internal thread of the adjustment seat 44 is connected to a screw 42 whose axial direction is consistent with its sliding direction. Both ends of the screw 42 are rotatably mounted on the top of the support cylinder 52 through the support 41. A connecting rod 45 is hinged to the top of the adjustment seat 44. One end of the connecting rod 45 away from the adjustment seat 44 is hinged to the bottom of the side support rod 2. When the screw 42 is rotated, the threaded structure between the screw 42 and the adjustment seat 44 engages, driving the adjustment seat 44 to move along the axial direction of the screw 42. When the adjustment seat 44 moves, it drives the side support rod 2 to swing through the connecting rod 45, thereby realizing the angle adjustment of the side support rod 2. As an example, the angle adjustment mechanism 4 adjusts the included angle between the side support rod 2 and the support cylinder 52 between 30° and 60°.
[0023] In some embodiments, two guide rods 43 parallel to the screw 42 are slidably disposed inside the adjusting seat 44, and the two ends of the guide rods 43 are fixedly connected to two supports 41; the adjusting seat 44 and the guide rods 43 are slidably connected, realizing the sliding setting of the adjusting seat on the top of the support cylinder 52.
[0024] In some embodiments, a hexagonal prism 46 is fixedly provided at one end of the screw 42; one end of the screw 42 is rotatably connected to and passes through the support 41, and a hexagonal prism 46 integrally formed with the screw 42 is concentrically fixed at this end of the screw 42. The hexagonal prism 46 can be clamped with a wrench, which facilitates the rotation of the screw 42, thereby adjusting the angle of the side support rod 2.
[0025] In some embodiments, the cross brace 1 has uniformly spaced adjustment holes 51, and the locking component is a bolt and nut mechanism 53 on the support cylinder 52 corresponding to the adjustment holes 51. The support cylinder 52 has a mounting through hole for mounting the bolt and nut mechanism 53. By aligning the mounting through hole with different adjustment holes 51 and locking it with the bolt and nut mechanism 53, the support cylinder 52 can be fixed at different positions on the cross brace 1, thereby achieving adjustment of the distance between the two side braces 2.
[0026] In some embodiments, the lifting mechanism 3 has a jack body 31, the top of the jack body 31 has a top seat 311, and the top of the top seat 311 is fixedly provided with an installation sleeve 32, which is fitted onto the end of the cross brace 1. The jack body 31 and the top seat 311 are utilizations of the prior art. In this embodiment, the installation sleeve 32 is welded and fixed to the top of the top seat 311. In use, the connection between the lifting mechanism 3 and the cross brace 1 is realized by fitting the installation sleeve 32 onto the end of the cross brace 1.
[0027] In some embodiments, such as Figure 2As shown, the cross brace 1 is provided with a limiting stop 11 corresponding to the mounting sleeve 32; the limiting stop 11 is fixedly provided on the outside of the cross brace 1, and it plays the role of limiting the installation of the mounting sleeve 32.
[0028] In some embodiments, as a specific implementation of the jack body 31, the jack body 31 is a scissor jack.
