Description

Technical Field

[0001] This invention relates to the field of tubular belt conveyor technology, specifically to a lifting tubular conveyor correction device. Background Technology

[0002] A tubular belt conveyor is a device that uses a coiled conveyor belt to form a tubular space, thereby enclosing and transporting materials.

[0003] During the material transport process of tubular belt conveyors, the pressure on the conveyor belt is often uneven due to a series of environmental factors such as the weight of the goods or their uneven distribution. In addition, due to factors such as installation errors of the idler rollers and frictional resistance, the tubular conveyor belt often deflects and deviates from the center line of the conveyor. This can cause material spillage along the line and reduce the conveyor's transport capacity, or even damage to the belt and render the conveyor unable to work.

[0004] Traditional correction methods mainly rely on manual adjustment, which requires stopping the tubular belt conveyor in advance. In addition, some correction devices and roller components are prone to damage to the conveyor belt when the deflection angle is too large. Therefore, it is of great significance to innovate and design a flexible and reliable new type of tubular conveyor correction device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a lifting tubular conveyor correction device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting tubular conveyor correction device, comprising a tubular conveyor belt and two fixed crossbars symmetrically arranged on the left and right sides, a base plate movably disposed between the top surfaces of the two fixed crossbars, and two base plates are provided. A correction roller frame is fixedly disposed in the middle of the top surface of the base plate by a first bolt. A right correction roller and a left correction roller are respectively rotatably disposed inside the two correction roller frames. Support frames are fixedly disposed on both sides of the top surfaces of the two base plates, and a roller frame is fixedly disposed on the opposite side of the two support frames by a second bolt. A roller is rotatably disposed inside the roller frame. A control part for driving the base plate to lift and lower is provided on the top surface of the fixed crossbars.

[0007] The control unit includes a three-phase asynchronous motor mounted on the surface of a fixed crossbar. One end of the output shaft of the three-phase asynchronous motor is equipped with a worm gear screw jack via a coupling, and a support plate is fixedly mounted on the extended end of the worm gear screw jack. The top surface of the support plate is fixedly connected to the bottom surface of the base plate.

[0008] Preferably, guide shafts are provided on both sides inside the support plate. The top end of the guide shaft passes through the bottom plate and extends to the top surface of the bottom plate. An upper circular flange is provided on the bottom surface of the support plate, and a lower circular flange is provided at the bottom end of the guide shaft. The bottom surface of the lower circular flange is fixedly connected to the top surface of the fixed crossbar. Both the lower circular flange and the upper circular flange are slidably sleeved on the surface of the guide shaft.

[0012] Beneficial effects

[0013] This invention provides a lifting tubular conveyor correction device, which has the following advantages compared with the prior art:

[0014] (1) The lifting tubular conveyor correction device has a high degree of automation. It can flexibly and reliably adjust the deflection angle of the tubular conveyor belt without stopping the tubular belt conveyor, thereby correcting the deviation. In addition, traditional correction devices often use the rotation of the roller assembly frame for correction, which is prone to jamming due to excessive deflection angle. In addition, the present invention has a simple structure, is easy to operate, has high correction accuracy, and has very low maintenance cost, and has strong practical application value.

[0015] (2) The lifting tubular conveyor correction device can adjust the angle of the correction roller frame and the roller frame by setting several first threaded holes and second threaded holes, that is, the angle of the left correction roller, the right correction roller and the roller, so as to meet different usage requirements and increase the scope of application.

[0016] (3) The correction device of the lifting tubular conveyor is connected to the guide shaft through the upper and lower round flanges in a hole-shaft fit, which plays a limiting role and prevents the bottom plate from getting too close to the tubular conveyor belt and causing damage.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please see Figures 1 to 5 As shown, the present invention provides a technical solution, with specific improvements as follows:

[0026] A lifting-type tubular conveyor correction device includes a tubular conveyor belt 2 and two fixed crossbars 3 symmetrically arranged on the left and right. The surface of each fixed crossbar 3 has mounting holes for fixed installation. A base plate 6 is movably arranged between the top surfaces of the two fixed crossbars 3, and two base plates 6 are provided. A correction roller frame 15 is fixedly mounted on the center of the top surface of each base plate 6 by a first bolt. A right correction roller 11 and a left correction roller 8 are rotatably mounted inside each of the two correction roller frames 15. Support frames 10 are fixedly mounted on both sides of the top surface of each of the two base plates 6, and a roller frame 9 is fixedly mounted on the opposite side of each of the two support frames 10 by a second bolt. A roller 1 is rotatably mounted inside each roller frame 9. The tubular conveyor belt 2 contacts the surfaces of the roller 1, the left correction roller 8, and the right correction roller 11 respectively to reduce belt wear. The top surface of the fixed crossbar 3 is provided with a control unit for driving the base plate 6 to lift and lower. The control unit includes a three-phase asynchronous motor 4 disposed on the surface of the fixed crossbar 3. One end of the output shaft of the three-phase asynchronous motor 4 is connected to a worm gear screw jack 7 via a coupling. The three-phase asynchronous motor 4 is connected to the worm gear screw jack 7 by bolt connection to ensure transmission stability. The extended end of the worm gear screw jack 7 is fixedly provided with a support plate 14. The top surface of the support plate 14 is fixedly connected to the bottom surface of the base plate 6. The worm gear screw jack 7 is an existing technology device and is widely used in industries such as machinery, metallurgy, construction, and water conservancy equipment. It has many functions such as lifting, lowering, propulsion with the aid of auxiliary parts, flipping, and various height position adjustments. It can accurately control and adjust the lifting or propulsion height according to a certain program. It can be directly driven by an electric motor or other power source, or it can be driven manually.

[0027] When the tubular conveyor belt 2, which has been loaded with material and deflected to the left, enters the correction device, the two three-phase asynchronous motors 4 below the left correction roller 8 are activated. The three-phase asynchronous motors 4 transmit torque to the worm gear screw jack 7 through worm gear meshing. At this time, the screw inside the worm gear screw jack 7 rotates. When the screw rotates, it pushes the support plate 14 to drive the bottom plate 6 to rise and move closer to the tubular conveyor belt 2. When the bottom plate 6 is close to the tubular conveyor belt 2, the idler frame 9 fixed on the support frame 10 is close to the tubular conveyor belt 2, so that the roller 1 on the idler frame 9 hugs the tubular conveyor belt 2. At the same time, the left correction roller 8 on the correction idler frame 15 hugs the tubular conveyor belt 2 and generates a radial force to achieve the correction effect.

[0028] Similarly, when the tubular conveyor belt 2 deviates to the right, the working principle is the same as described above. It is only necessary to start the two three-phase asynchronous motors 4 below the right correction roller 11, so that the right correction roller 11 rises until it grips the tubular conveyor belt 2. The roller 1, the right correction roller 11 and the left correction roller 8 can roll relative to the tubular conveyor belt 2, without affecting the normal transportation of upstream and downstream, ensuring transportation efficiency and high efficiency and reliability of correction effect.

[0029] Example 2

[0030] Based on Example 1, please refer to Figures 1 to 4 As shown, the specific improvements are as follows:

[0031] The top surface of the base plate 6 is provided with a first threaded hole that matches the first bolt, and the surface of the support frame 10 is provided with a second threaded hole that matches the second bolt, and both the second threaded hole and the first threaded hole are provided in multiples.

[0032] The presence of several first threaded holes and second threaded holes allows for adjustment of the angles of the straightening roller frame 15 and the roller frame 9 to meet different usage requirements and expand the applicability range.

[0033] Example 3

[0034] Based on Example 2, please refer to Figure 1 , Figure 2 as well as Figure 5 As shown, the specific improvements are as follows:

[0035] The support plate 14 has guide shafts 5 on both sides inside. The top of the guide shaft 5 passes through the bottom plate 6 and extends to the top surface of the bottom plate 6. The bottom surface of the support plate 14 is provided with an upper circular flange 13, and the bottom end of the guide shaft 5 is provided with a lower circular flange 12. The bottom surface of the lower circular flange 12 is fixedly connected to the top surface of the fixed crossbar 3. The lower circular flange 12 and the upper circular flange 13 are slidably sleeved on the surface of the guide shaft 5.

[0036] The use of the upper round flange 13 improves the stress condition of the parts. The upper round flange 13 and the lower round flange 12 are connected to the guide shaft 5 by a hole-shaft fit, which plays a limiting role and prevents the bottom plate 6 from getting too close to the tubular conveyor belt 2 and causing damage.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
