Description

Technical Field

[0001] This utility model relates to the field of belt idler replacement technology, specifically a belt idler replacement device. Background Technology

[0002] During the long-term operation of belt conveyors, idlers, as key support components, often experience wear, deformation, jamming, or damage due to prolonged material load, material impact, or environmental corrosion. If these damaged idlers are not replaced promptly, it can lead to belt misalignment, accelerated wear, or even system shutdown, affecting the normal operation of the entire conveying system. Therefore, regular inspection and replacement of belt idlers are crucial maintenance procedures to ensure the stable and reliable operation of belt conveyors.

[0003] Traditional methods for replacing belt idlers require the use of large tools such as hand-operated hoists for disassembly and assembly. The process is cumbersome and complex, requires multiple people to work together, and is time-consuming. This makes it inefficient for maintenance tasks with a large number of replacements and tight deadlines. At the same time, existing support devices are often structurally fixed and cannot be flexibly adjusted according to different site conditions, resulting in poor adaptability and seriously affecting maintenance progress and work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A belt idler replacement device includes a support tube with curved corners at both ends of the top surface of the support tube. Two sliding blocks are symmetrically installed at the bottom end of the support tube by bolts. The inside of the support tube opposite to the sliding blocks is solid. The sliding blocks are slidably installed in sliding grooves. The sliding grooves are symmetrically opened at the top of the connecting blocks. The bottom ends of the connecting blocks extend in the length direction on both sides to form extension blocks. The extended rotating blocks are respectively installed inside the first rotating clamp via pins, and the first rotating clamp is symmetrically installed at both ends of the upper rotating plate. The first rotating clamp at the other end of the upper rotating plate has rotating blocks installed inside by pins, and a threaded rod passes through the middle of the rotating block. One of the rotating blocks is connected to the threaded rod via a bearing, and the other rotating block is threadedly engaged with the threaded rod. An internal hexagon block is fixedly installed at the end of the threaded rod connected to the bearing. The other end of the rotating block is respectively installed between the second rotating clamps via pins, and the second rotating clamps are respectively symmetrically installed at one end of the lower rotating plate.

[0006] Preferably, the other end of the lower rotating plate is symmetrically installed inside the support frame plate via pins, and the bottom end of the support frame plate is bolted to a support plate.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Please refer to... Figures 1-4 As shown, this utility model provides a technical solution: A belt idler replacement device includes a support tube 101 with curved corners at both ends. Two sliding blocks 102 are bolted to the middle of the support tube 101. The interior of the support tube 101 is solid at the point opposite to the sliding blocks 102. The sliding blocks 102 are slidably installed in sliding grooves 103. The sliding grooves 103 are symmetrically opened at the top of a connecting block 104. The bottom ends of the connecting block 104 extend in the length direction on both sides to form extension rotating blocks 105.

[0012] The above scheme achieves the protection function of dispersing contact stress and preventing cuts when supporting the belt by making the top corner of the support tube curved; a detachable rigid connection with the connecting structure is established by symmetrically installing two sliding blocks at the bottom of the support tube with bolts; the solid part of the support tube opposite the sliding blocks ensures the structural integrity of the bolt fastening part; the sliding blocks are slidably installed in the sliding groove to provide the support tube with the freedom of movement in the horizontal direction; the sliding groove is symmetrically opened at the top of the connecting block to provide a precise linear movement track for the sliding block; and the two sides of the bottom of the connecting block extend in the length direction to form an extension rotating block, providing the installation base for subsequent hinge rotation.

[0013] In this embodiment, the extension rotating blocks 105 are respectively installed inside the first rotating clamps 106 by pins, and the first rotating clamps 106 are respectively symmetrically arranged at both ends of the upper rotating plate 107.

[0014] The above scheme achieves a rotational connection between the connecting block and the upper rotating plate by extending the rotating blocks and installing them inside the first rotating clamp via pins; and a stable double-sided force transmission mechanism is formed by symmetrically installing the first rotating clamps at both ends of the upper rotating plate.

[0015] In this embodiment, a rotating block 108 is installed inside the first rotating clamp 106 at the other end of the upper rotating plate 107 via a pin, and a threaded rod 109 passes through the middle of the rotating block 108.

[0016] With the above scheme, the rotational motion of the threaded rod is linked with the rotation of the upper rotating plate 107 by means of rotating blocks installed inside the first rotating clamp at the other end of the upper rotating plate via pins; the rotational drive is converted into the linear movement of the rotating block by means of the threaded rod passing through the middle of the rotating block.

[0017] In this embodiment, one rotating block 108 is connected to the threaded rod 109 via a bearing, and the other rotating block 108 is threadedly engaged with the threaded rod 109. An internal hexagon block 110 is fixedly installed on the end of the threaded rod 109 located at the bearing connection.

[0018] The above scheme provides rotational support for the threaded rod by connecting one of the rotating blocks to the threaded rod via a bearing, while allowing it to rotate freely. The rotational motion of the threaded rod is converted into linear movement by the other rotating block through a threaded engagement with the threaded rod. A hexagonal socket block is fixedly installed at one end of the threaded rod connected to the bearing to provide a standard tool interface for inputting torque.

[0019] In this embodiment, the other end of the rotating block 108 is respectively installed between the second rotating clamping plates 111 by pins, and the second rotating clamping plates 111 are respectively symmetrically installed at one end of the lower rotating plate 112.

[0020] With the above scheme, the other end of the rotating block is installed between the second rotating clamping plates 111 via pins to achieve a movable connection between the rotating block and the lower rotating plate; the second rotating clamping plates are symmetrically installed at one end of the lower rotating plate to form the rotation execution components of the lower rotating plate.

[0021] In this embodiment, the other end of the lower rotating plate 112 is symmetrically installed inside the support frame plate 113 by means of pins, and the bottom end of the support frame plate 113 is fitted with a support plate 114 by bolts.

[0022] The above scheme provides a fixed rotation fulcrum for the entire lifting mechanism by symmetrically installing the other end of the lower rotating plate inside the support frame plate via pins; the support plate 114 is bolted to the bottom of the support frame plate 113 to achieve a detachable connection between the entire device and the external foundation structure; the support plate serves as the load-bearing base of the entire device to transfer the working load to the foundation structure below; and the replaceable design of the support plate enables the length to be adapted according to the size requirements of different on-site support structures.

[0023] In this embodiment, when the belt roller replacement device is in use, the hexagonal block 110 serves as a power input interface and can be plugged into a manual or electric crank. When it is rotated, it directly drives the threaded rod 109 to rotate. Since the threaded rod 109 is rotatably connected to one side of the rotating block 108 through a bearing and to the other side of the rotating block 108 through a thread, the rotational motion is converted into linear movement of the threaded rotating block 108, thereby gradually reducing the distance between the two rotating blocks 108. This contraction motion forces the upper rotating plate 107 and the lower rotating plate 112, which are equipped with the rotating blocks 108, to rotate relative to each other: the upper rotating plate 107 rotates with the connection point of the extended rotating blocks 105 at both ends as the axis, while the lower rotating plate 112 rotates with the pin connected to the support frame plate 113 as the axis.

[0024] As the distance between the rotating blocks 108 continues to decrease, the angle between the upper rotating plate 107 and the lower rotating plate 112 changes, pushing the connecting block 104 to move upward as a whole. The sliding groove 103 on the connecting block 104 cooperates with the sliding block 102, so that the connecting block 104 rises smoothly in the vertical direction. The sliding block 102 is fixedly connected to the bottom of the support tube 101 by bolts. Therefore, the upward movement of the connecting block 104 drives the support tube 101 to rise synchronously. The curved corner structure at the top of the support tube 101 gradually contacts and supports the belt during the upward process. Its arc design avoids hard contact between the sharp edges and the belt surface, effectively preventing the belt from being scratched or worn.

[0025] The section inside the support pipe 101 corresponding to the installation position of the sliding block 102 is a solid structure. This design increases the compressive strength and rigidity of this area, ensuring that the pipe wall does not collapse or deform when the bolts are tightened, thereby ensuring the connection stability during long-term use. The entire lifting force is finally transmitted to the bottom support plate 114 through the support frame plate 113. The support plate 114 serves as the base of the entire device and can be replaced with different lengths according to the specific size requirements of the on-site support structure, distributing the load to the foundation structure below and maintaining the system stability during the lifting process.

[0026] The sliding engagement design of the sliding block 102 and the sliding groove 103 allows the support tube 101 to be quickly adjusted in installation position and locked in place with bolts. This feature ensures that the center point of the support tube 101 can be quickly and accurately aligned and installed on the connecting block 104. It also enables rapid alignment and installation when replacing support tubes 101 of different lengths. This device combines mechanical transmission with the lever principle to achieve the function of controlling the vertical displacement of the belt through rotational operation, improving the efficiency and safety of idler roller replacement operations while ensuring structural strength.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
