Abstract
Description
Technical Field
[0001] The invention belongs to the field of circular tube belt conveyors, and in particular relates to a deviation correction device and a deviation correction system for circular tube belt conveyors. Background Art
[0002] According to field experience, there is a big difference between flat belt correction and tube belt correction. When the conveyor belt deviates in the unfolded state, the forward tilting or lifting of the rollers is conducive to correction. However, for tube belts, lifting the rollers can easily cause excessive deflection of the tube belt, which is often not conducive to correction. The correction effect is good when the rollers are tilted forward. If all rollers are tilted forward as a whole, the correction effect is best. At present, for the correction of circular tube belt conveyors, generally only 1~2 rollers are adjusted. There are several ways to correct the deviation: manual correction, motor control and connecting rod mechanism correction: the correction method of manually loosening bolts and nuts to change the installation angle of the rollers, or adding gaskets at the ends of the rollers requires shutdown, which is inefficient; the environment along the circular tube belt conveyor is generally harsh, and it is difficult to get electricity. The reliability of the motor with push rods, screw nuts or gears is poor; the correction speed through the connecting rod mechanism is slow and the correction effect is not ideal.
[0003] The existing pipe-belt linkage deviation correction technology (such as DE 102008024) has the problem of multiple sets of rollers being tilted as one, and the deviation correction function of each deviation adjustment roller cannot be fully exerted. The squeezing pressure on the conveyor belt will cause the round pipe to continue to deviate.
[0004] In order to solve the above technical problems, the present invention is proposed to realize the simultaneous movement of multiple rollers, give full play to the deviation correction ability of each deviation adjustment roller, and effectively improve the deviation correction efficiency. Summary of the invention

[0006] The object of the present invention is achieved in this way. A circular tube belt conveyor correction device is provided, which includes a correction component acting on a circular tube belt conveyor support frame.

[0009] The present invention is designed that when the piston rod of the pushing device moves, the end of the deflection adjusting roller connected to the first pin shaft moves with the piston rod, and the other end rotates around the second pin shaft, so that the deflection adjusting roller rotates around the second pin shaft.
[0010] The present invention is designed that the annular array of the correction components is on the circular tube belt conveyor support frame to form a correction channel to constrain the conveyor belt into a circular tube structure. The annular array of the correction components is on one side or both sides of the circular tube belt conveyor support frame.

After the pipe belt returns to the correct position, the signal acquisition unit collects data and feeds it back to the host computer system, the electromagnetic valve resumes action, and the automatic correction is completed.
[0014] The power station is a hydraulic station or a pneumatic station, wherein one hydraulic station or pneumatic station can provide pressure for multiple groups of deviation-correcting roller assemblies at the same time.

In the present invention, a single-point single control is adopted, and each pushing device controls a deviation adjustment roller.

[0020] The present invention will be further described in detail below in conjunction with embodiments. The advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the protection scope of the present invention.
[0021] Figure 1 It is the main view of the correction component structure; Figure 2 It is a top view of the structure of the correction component; Figure 3 It is an axonometric drawing of the double-sided arrangement of the deflection correction components; Figure 4 It is an axonometric drawing of the one-side arrangement of the deflection correction components; Figure 5 It is a schematic diagram of synchronous hydraulic control of six groups of hydraulic cylinders connected in series; Figure 6This is a schematic diagram of the movement of each deviation adjustment roller during the deviation correction process. Figures 1 to 6 As shown, the present invention provides a correction device for a round tube belt conveyor, comprising correction components acting on a round tube belt conveyor support frame 1, wherein the plurality of correction components are arranged adjacent to each other on the round tube belt conveyor support frame 1 to form a correction channel, and the pipe belt 9 curled into a round tube passes through the channel. Each correction component can move independently, realizing the simultaneous movement of multiple correction rollers, giving full play to the correction ability of each correction roller 2, and effectively improving the correction efficiency.
[0022] like Figures 1 to 4 As shown, the deviation correction component includes a base 3, a deviation adjustment roller 2 arranged on the base and a push device 7. The push device 7 is fixed on the base 3, and has a piston rod 71 on the push device 7, and a first pin 6 is arranged on the piston; one end of the deviation adjustment roller 2 is hinged on the base 3 through the second pin 4, and the other end is provided with a slide 5, which is connected to the first pin 6 of the piston rod 71 of the push device 7 through the slide 5. When the piston rod 71 of the push device 7 moves, the end of the deviation adjustment roller connected to the first pin moves with the piston rod 71, and the other end rotates around the second pin 4, so that the deviation adjustment roller rotates around the second pin. The circular array of the deviation correction component is on the support frame 1 of the circular tube belt conveyor to form a deviation correction channel, constraining the conveyor belt into a circular tube structure, and the circular array of the deviation correction component is on one side or both sides of the support frame 1 of the circular tube belt conveyor. The push devices 7 on each deviation adjustment roller 2 are interconnected through pipelines to achieve synchronous linkage of multiple groups of push devices 7.
[0023] In this embodiment, if Figure 6 As shown, the pushing device is provided with an electromagnetic reversing valve for controlling the extension and retraction direction of the pushing device 7, wherein the pushing device is a double-acting hydraulic cylinder or a pneumatic cylinder.
[0024] In this embodiment, a circular tube belt conveyor deviation correction system is provided, comprising a signal acquisition unit, a signal transmission unit, a host computer system, a power station and the deviation correction device as described above, wherein the circular tube belt conveyor deviation correction device is in operation. The correction angle of each roller in the correction system is collected by calculation, simulation and simulated measurement. Since the deflection angle of each correction roller 2 is different, the deflection angle of each correction roller is pre-set and formed into a database and entered into the host computer system. When the signal acquisition unit collects the data of the deviation of the pipe belt 9, the signal transmission unit feeds back the data to the host computer system. The host computer system issues an instruction based on the received deviation data to control the action of the electromagnetic reversing valve, and the piston rod 71 on the pushing device 7 starts to move. The two groups of correction rollers deflect collectively to correct the deviation of the pipe belt 9. After the pipe belt 9 is straightened, the signal acquisition unit collects data and feeds it back to the host computer system, the electromagnetic valve resumes action, and the automatic correction is completed.
[0025] In a specific embodiment, the power station may be a hydraulic station or a pneumatic station, wherein one hydraulic station or one pneumatic station may provide pressure for multiple groups of deviation-correcting roller assemblies simultaneously.
[0026] In this embodiment, in this embodiment, as Figure 5 A synchronous hydraulic control connection method of six groups of hydraulic cylinders in series is shown. In specific implementation, no matter how many offset rollers 2 are adjusted on a support frame 1, it can ensure synchronous clockwise or counterclockwise movement, and the extension and retraction direction of the hydraulic rod can be controlled by the electromagnetic reversing valve. Figure 5 As shown in the figure, the forward and backward movement of the hydraulic cylinder is controlled by the three-position four-way reversing valve at the bottom. The hydraulically controlled one-way valve composed of the two-position three-way reversing valve and the one-way valve is mainly used for the initial oil filling process. Since the push device is in a cavity state at the beginning, it is necessary to use the hydraulically controlled one-way valve to control the hydraulic oil to fill the push devices 71#, 2#, 3#... in sequence. The dotted line is the control oil circuit of the one-way valve.
[0027] In this embodiment, combined with Figure 5 and Figure 6 As shown, the correction device with a single row of correction rollers is taken as an example to demonstrate the correction principle mentioned above. When the pipe belt is offset, the six correction rollers collectively tilt forward and generate correction angles θ1~θ6 at the same time. For example, the correction roller at the top that generates a correction angle of θ1 returns the pipe belt to the right position through friction during rotation. The other five correction rollers deflect according to the preset angles θ2~θ6 in the data to jointly correct the pipe belt. Multiple groups of such correction components are arranged at intervals along the pipe belt, and the correction is made in full consideration of the different deviations of the pipe belt in the linear direction; for each correction component, the different radial forces of the pipe belt in the same cross section are fully considered, and different correction rollers in a group of correction components use different correction angles for correction, which ensures that the correction device can accurately correct the deviation from the line to the surface system, and improves the efficiency and accuracy of the correction work.
[0028] In the above-mentioned circular tube belt conveyor correction system, the hydraulic cylinder of the pushing device controls the extension and retraction direction through an electromagnetic reversing valve, and the hydraulic cylinder of the pushing device 7 adopts a three-position four-way reversing valve to control the forward / retractive movement of the pushing device 7. One hydraulic station can provide pressure for the deviation adjustment roller 2 assemblies on multiple frames at the same time. In order to ensure the swing stability of the deviation adjustment roller 2, the pushing device is preferably a double-acting oil cylinder or air cylinder. In other embodiments, a single-acting lever can also be used instead of a double-acting cylinder.
[0029] In the above-mentioned round tube belt conveyor deviation correction system, a joint 72 is also provided in the hydraulic circuit, and the joint 72 includes a female head and a male head. The female head is installed on the rear cover of the push device 7 and is connected with the male head hydraulic connection pipe 8 to form a complete hydraulic circuit. When the male head and the female head are connected, it is a passage, and it is locked after being disconnected. The joint 72 can be a quick-press joint 72 or a common joint 72. When the quick-press joint 72 is used, it has the advantages of being plug-in and use-and-play, and being self-locking when disconnected.
[0030] In other embodiments, the deviation correction method can also adopt two modes: electric or manual. The electric mode is hydraulic transmission using an electric reversing valve and an electric hydraulic pump to control the movement of the deviation adjustment roller 2 for deviation correction. The manual mode is hydraulic transmission using a manual reversing valve and a hand pressure jack to control the movement of the deviation adjustment roller 2 for deviation correction. When it is difficult to obtain electricity along the way, the manual method should be used.
[0031] In actual production, if it is difficult to obtain electricity along the line, manual control can also be used to connect the male and female heads of the quick-plug connector 72 to form a complete hydraulic circuit, and manually control the action of the electromagnetic reversing valve to control the movement of the piston rod 71. Due to the interconnection, the piston rods 71 of multiple groups of push devices 7 extend forward or retract backward at the same time, and all piston rods 71 drive their respective deviation adjustment rollers 2 to swing relative to the hinge axis, so that all adjustments are tilted forward at the same time to correct the deviation of the pipe belt 9, and there is no need to operate each deviation adjustment roller 2 separately. When several deviation adjustment rollers 2 are adjusted to the appropriate swing angle, the middle position function of the reversing valve is used to maintain pressure to prevent the piston rod 71 from returning to its original position, and then the connector 72 is disconnected to lock the connector 72 to prevent oil leakage. At this point, the deviation correction work is completed.
[0032] The above-mentioned invention is adopted to realize the deviation correction of the pipe belt 9 of the round pipe belt conveyor, which is simple, convenient, stable and reliable. In the present invention, a single-point single control is adopted, and each push device 7 controls a deviation adjustment roller 2. The offset angle of each deviation adjustment roller 2 is different, instead of controlling the roller bracket to synchronously control the roller to complete the rotation. The present invention has good flexibility and accurate deviation correction. In the present invention, the hydraulic or pneumatic synchronous circuit interconnected by the push device 7 realizes the forward tilt correction of all deviation adjustment rollers 2 at the same time, and the linkage at the same time, which has good effect, avoids the risk of climbing operation, has high safety, and the linear contact area between the deviation adjustment roller 2 and the pipe belt 9 is small.
[0033] The implementation schemes in the above embodiments can be further combined or replaced, and the embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various changes and improvements made to the technical solutions of the present invention by professional and technical personnel in this field all belong to the protection scope of the present invention.
