Description

Technical Field

[0001] This invention belongs to the field of pneumatic mechanical device repair technology, and particularly relates to a pneumatic platform for shaping the idler roller frame on a belt conveyor. Background Technology

[0002] Belt conveyors are relatively simple in structure, easy to install and maintain, and feature long-distance, continuous transportation capabilities, making them a major component of underground transportation systems in coal mines. They are primarily used for transporting coal and gangue from mining and tunneling faces. The underground coal flow transportation system in a coal mine mainly consists of a face transportation system and a main transportation system, with multiple belt conveyors interconnected to transport coal from the face to the coal bunker at the bottom of the mine, covering a total length of over 10,000 meters. The idler rollers on belt conveyors are typically spaced 1 to 1.5 meters apart, and the extremely long transportation distance necessitates a large number of idler rollers in use.

[0003] The upper idler frame of a belt conveyor supports the upper load-bearing belt. During use, external forces can cause the upper idler frame to twist or bend, resulting in significant maintenance workload and difficulty. Ignoring this leads to waste and increased production costs, contradicting the company's economic development policy. Therefore, finding a quick and simple way to repair twisted or bent upper idler frames of belt conveyors has become a crucial problem that must be solved in maintenance work. Summary of the Invention

[0004] The purpose of this invention is to provide a pneumatic platform for shaping the idler rollers on a belt conveyor, so as to solve the technical problem of slow efficiency in traditional maintenance work.

[0005] To solve the above-mentioned technical problems, the specific technical solution of the present invention is as follows: In some embodiments of this application, a pneumatic platform for shaping idler rollers on a belt conveyor is provided, comprising: a platform base, and a torsion shaping unit and a bending shaping unit disposed on the platform base; The torsion shaping unit includes: A torsion support fixed to one end of the platform base; A fixed support is fixed to the other end of the platform base; The torsion device is rotatably connected to the torsion support via a rotating shaft; the torsion device includes a holder for holding one end of the upper roller frame, and two torsion telescopic piston cylinders symmetrically arranged on both sides of the rotating shaft; the cylinder bodies of the two torsion telescopic piston cylinders are hinged to the platform base, and the piston rod ends are fixedly connected to the rotating shaft; the two torsion telescopic piston cylinders are configured to drive the rotating shaft and the holder to rotate about its axis by one extending and the other retracting. The bending shaping unit includes: A slide rail device fixedly installed on the platform base; And a clamping device slidably disposed on the slide rail device; the clamping device includes a fixed connecting seat, an upper clamping seat fixed to the upper part of the fixed connecting seat by an upper clamping seat connecting arm, a clamping telescopic piston cylinder, and a lower clamping seat that is driven to rise and fall by the clamping telescopic piston cylinder.

[0006] In some embodiments of this application, the end of the piston rod is fixedly connected to the rotating shaft by a clamping mechanism.

[0007] In some embodiments of this application, the compression telescopic piston cylinder is fixed to the lower part of the fixed connecting seat, and its piston rod extends upward and is connected to the lower compression seat.

[0008] In some embodiments of this application, a compressed air pipeline system and an operating console are also included. The operating console is connected to the torsional telescopic piston cylinder and the pressing telescopic piston cylinder through the compressed air pipeline system, and is provided with control valves for controlling the operation of each pneumatic cylinder.

[0009] In some embodiments of this application, the slide rail device includes a slide rail base and at least one slide rail fixed thereon, and the bottom of the fixed connection seat of the clamping device is provided with a sliding sleeve that matches the slide rail.

[0010] In some embodiments of this application, a method for shaping the upper idler roller frame using the aforementioned pneumatic device is disclosed, comprising the following steps: Step 1) Fix both ends of the upper roller frame to the card seat of the torsion device and the fixed support respectively; control the two torsion telescopic piston cylinders so that the piston rod of one extends and the piston rod of the other retracts, thereby driving the rotating shaft and the card seat to rotate, thereby applying torque to the upper roller frame and correcting its torsional deformation.

[0012] Various other advantages and benefits will become apparent to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the invention. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings: Figure 1 This is a schematic diagram of the overall structure provided for an embodiment of the present invention. Detailed Implementation

[0013] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0014] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0015] See appendix Figure 1 As shown, according to some embodiments of this application, a pneumatic platform for shaping upper idler frames on a belt conveyor is provided. This device is an integrated maintenance platform designed to efficiently repair two main deformations of the upper idler frames: torsional deformation and bending deformation.

[0016] The core foundation of the device is a platform base 1. The base 1 is welded from heavy steel (such as channel steel and steel plates) to form a rectangular frame with high rigidity and stability, which is sufficient to withstand the huge reaction force generated during the shaping process.

[0017] The platform base 1 is integrated with a torsion shaping unit and a bending shaping unit.

[0018] The torsion shaping unit is responsible for correcting the torsional deformation of the upper idler roller frame, and its structure and connection relationship are as follows: Torsional support 2 and fixed support 6 are two steel structure supports, which are fixed to both ends of the platform base 1 by high-strength bolts. The top of the fixed support 6 is provided with a slot for positioning one end of the upper roller frame.

[0019] The torsion device 3 is rotatably connected to the upper part of the torsion support 2 via a horizontal rotating shaft 31, which is preferably made of alloy steel and heat-treated to ensure its torsional strength.

[0020] The torsion device 3 specifically includes: The upper roller bracket holder 32 is fixedly installed on the rotating shaft 31 and is used to hold the other end of the upper roller bracket.

[0021] Two torsional telescopic piston cylinders 33 are symmetrically arranged on both sides of the rotating shaft 31. The cylinder bodies of the two torsional telescopic piston cylinders 33 are hinged to the platform base 1 (specifically, hinged to a specially welded lug plate on the base 1), and the piston rod ends are fixedly connected to the rotating shaft 31. In a preferred embodiment, this fixed connection is achieved by a clamping mechanism (e.g., a pair of clamps and fastening bolts).

[0022] When compressed air drives the piston rod of one side of the torsional telescopic piston cylinder 33 to extend, while the piston rod of the other side of the torsional telescopic piston cylinder 33 retracts, the forces acting on both sides of the rotating shaft 31 form a torque. This torque drives the rotating shaft 31 and the mounting bracket 32 ​​fixed thereon to rotate around the axis of the rotating shaft. Since the other end of the upper roller frame is locked by the fixed support 6, this rotational torque is converted into a pure torque to correct the torsional deformation.

[0023] The bending and shaping unit is responsible for correcting the bending deformation of the upper roller frame. The slide rail device 4 is fixedly installed on the platform base 1. The slide rail device 4 includes a slide rail base 41 and at least one slide rail 42 fixed thereon. Preferably, the slide rail 42 is two parallel linear guide rails.

[0024] The clamping device 5 is slidably mounted on the slide rail device 4. Specifically, the bottom of the clamping device 5 is provided with a sliding sleeve that matches the slide rail 42, allowing it to move freely along the slide rail.

[0025] The specific structure of the clamping device 5 includes: Fixed connector 51; The upper clamping seat connecting arm 52 has its lower end fixed to the top crossbeam of the fixed connecting seat 51; The upper clamping seat 53 is fixedly installed at the upper end of the upper clamping seat connecting arm 52; The telescopic piston cylinder 55 is pressed and its cylinder body is fixed to the lower part of the fixed connecting seat 51.

[0026] The lower clamping seat 54 is fixedly connected to the end of the piston rod extending upward from the clamping telescopic piston cylinder 55, and is driven to rise and fall by the clamping telescopic piston cylinder 55.

[0027] By using the sliding clamping device 5, the upper and lower clamping seats (53, 54) are positioned directly below the bent part of the roller frame. The piston rod of the clamping telescopic piston cylinder 55 is extended, driving the lower clamping seat 54 to rise, which, together with the fixed upper clamping seat 53, applies a vertical clamping force to the bent part, thereby achieving straightening.

[0028] The device also includes a compressed air piping system and an operating console (not shown in the figure). The operating console is connected to the torsional telescopic piston cylinder 33 and the clamping telescopic piston cylinder 55 via the compressed air piping system. The operating console is equipped with control valves (such as three-position four-way directional valves) and handles for controlling the operation of each pneumatic cylinder, enabling precise control of the shaping process.

[0029] The upper roller frame is fixed at both ends to the clamping seat 32 and the fixed support 6 of the torsion device. The two torsion telescopic piston cylinders 33 are controlled to extend one and retract the other, driving the rotating shaft 31 and the clamping seat 32 to rotate, applying torque to correct the torsional deformation. After the upper roller frame is fixed, the pressing device 5 is moved to below the bent part, and the piston rod of the pressing telescopic piston cylinder 55 is controlled to extend, driving the lower pressing seat 54 to rise, and together with the upper pressing seat 53, pressing the bent part to correct the bending deformation.

[0030] The technical effects achieved by the above technical solution in the embodiments of this application are as follows: The pneumatic device provided by this invention uses compressed air as power, avoiding environmental pollution caused by hydraulic oil leakage; it generates torque by driving the rotating shaft through symmetrical pneumatic cylinders to accurately correct the tortuous deformation of the upper idler frame, and at the same time uses a movable clamping device to effectively repair bending deformation; the whole device has a compact structure and is easy to operate, which significantly reduces the labor intensity of maintenance personnel, greatly improves the efficiency of repair work, and realizes the reuse of the idler frame.

[0031] Powered by compressed air, it is safe and environmentally friendly; it achieves efficient pure torque torsion shaping through the principle of force couple, and integrates with the clamping shaping function. It has a compact structure, is easy to operate, and greatly improves repair efficiency and quality while reducing labor intensity and production costs.
