Description

Technical Field

[0001] The utility model relates to the technical field of port machinery, in particular to a passive hydraulic automatic deviation-correcting device for a bidirectional belt conveyor. Background Art

[0002] A belt conveyor, also known as a belt conveyor, is a continuously moving belt that carries material and is driven by a drive mechanism. Belt conveyors are categorized as either one-way or two-way. They offer advantages such as high transport capacity, stable operation, low failure rates, and ease of automated control, significantly improving port operations efficiency.

[0003] In port yard operations, belt conveyors are used to transfer cargo such as coal, ore, and bauxite unloaded from ships to designated storage areas via conveyor belts. Belt conveyors also play a vital role in ship loading operations, transporting cargo from the yard to the ship's deck for loading. Belt conveyors are also used to transfer cargo within warehouses and transport cargo from warehouses to loading platforms. With the diversification of port operations, bidirectional belt conveyors are widely used, as ground belt conveyors require constant switching between forward and reverse rotation.

[0004] Due to the shortcomings of the belt conveyor such as unstable installation foundation and poor operation, as well as factors such as load changes and changes in falling material impact, the belt is prone to deviation during the forward or reverse rotation of the belt conveyor. When the belt conveyor has deviation problems, it is necessary to manually adjust the correction roller group to correct the belt deviation, which is inconvenient to operate. Utility Model Content

[0005] The embodiment of the present application provides a passive hydraulic automatic deviation correction device for a bidirectional belt conveyor, which solves the technical problem in the prior art that manual correction is required when the belt conveyor deviates, which is inconvenient to operate.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a passive hydraulic automatic deviation correction device for a bidirectional belt conveyor, comprising a roller assembly and a support mechanism located below the roller assembly, vertical plates are installed at both ends of the support mechanism, and transverse brackets are installed at the lower parts of the two vertical plates, and a detection and driving mechanism is installed at one end of the transverse bracket; the bottom of the roller assembly is rotatably installed above the support mechanism, and rollers are provided at the bottom of the roller assembly near its two ends, and correspondingly, roller brackets are installed near the two ends of the support mechanism, and the roller brackets can be supported under the corresponding rollers; a mounting column is fixed to one side of the support mechanism, and an oil cylinder is installed on the mounting column, and the oil cylinder is connected to the detection and driving mechanism through an oil pipe, and the protruding end of the oil cylinder is connected to one side of the roller assembly.

[0007] Since both ends of the support mechanism are equipped with detection and drive mechanisms through transverse brackets, the roller assembly is installed above the support mechanism, and an oil cylinder is installed on one side of the support mechanism, and the oil cylinder is connected to the detection and drive mechanism through an oil pipe, when the belt deviates, it will contact the detection and drive mechanism, thereby driving the oil cylinder to move. The movement of the oil cylinder can drive the angle of the roller to change, thereby realizing automatic correction of the belt.

[0008] Furthermore, the detection and driving mechanism includes a correction detection wheel, a correction oil pump and an oil storage box. An oil pump mounting plate is fixed to one side of the correction oil pump, and the oil pump mounting plate is installed at one end of the transverse bracket; therefore, when the belt deviates, the deviated belt will rub against the correction detection wheel, driving the correction detection wheel to rotate, and then the correction oil pump will suck the hydraulic oil from the oil storage box and output it to the oil cylinder.

[0009] Furthermore, a channel steel is fixed to one end of the transverse bracket for installing the inspection and drive mechanism, and the bottom of the oil pump mounting plate is rotatably mounted in the slot at one end of the channel steel. A fixing plate is vertically provided on one side of the oil pump mounting plate, and both sides of the fixing plate are respectively connected to the two flanges of the channel steel.

[0010] Furthermore, the two flanges of the channel steel are hinged with swing pins, and a spring is embedded in the outer periphery of the swing pin. Correspondingly, strip holes are provided on both sides of the fixed plate, and the upper ends of the two swing pins pass through the strip holes on both sides of the fixed plate and are installed with nuts. The spring abuts against the bottom of the fixed plate; therefore, when the belt deviates, the detection and drive mechanism can buffer and avoid to the side to avoid direct impact of the belt, thereby reducing wear on the belt edge and the detection and drive mechanism and extending the service life.

[0011] Furthermore, the roller assembly includes a roller and a roller frame. The roller frame is located below the roller, and the two ends of the roller are rotatably mounted on the two ends of the roller frame respectively; a rotating shaft is provided in the middle position of the bottom of the roller frame, and the rotating shaft is rotatably mounted in the middle of the support mechanism.

[0012] Furthermore, the supporting mechanism includes a supporting rod fixed between the two vertical plates, a supporting seat is fixed in the middle of the supporting rod, a circular hole is provided on the supporting seat, and the rotating shaft is installed in the circular hole of the supporting seat.

[0013] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages:

[0014] Because the detection and drive mechanisms are installed at both ends of the support mechanism through transverse brackets, the roller assembly is installed above the support mechanism, and a cylinder is installed on one side of the support mechanism. The cylinder is connected to the detection and drive mechanism through an oil pipe. Therefore, when the belt deviates, it will contact the detection and drive mechanism, thereby driving the cylinder to move. The movement of the cylinder can cause the angle of the roller to change, thereby achieving automatic correction of the belt. This solves the technical problem of the existing technology that manual correction is required when the belt conveyor deviates, which is inconvenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of this patent, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of this patent.

[0021] The utility model discloses a passive hydraulic automatic deviation-correcting device for a bidirectional belt conveyor, comprising a roller assembly and a support mechanism, wherein the roller assembly is movably mounted above the support mechanism. In one example, the passive hydraulic automatic deviation-correcting device for a belt conveyor further comprises two detection and drive mechanisms and an oil cylinder 7, wherein the oil cylinder 7 is connected to the detection and drive mechanisms via an oil pipe, and the extended end of the oil cylinder 7 is connected to the roller assembly. When the extended end of the oil cylinder 7 is extended or retracted, the roller assembly can swing relative to the support mechanism.

[0022] like Figure 1As shown, the support mechanism includes a support rod 1 and a support seat 2. The support seat 2 is located in the middle of the support rod 1, and the movable installation of the roller assembly can be achieved through the support seat 2. Specifically, the roller assembly includes a roller 3 and a roller frame 4. The roller frame 4 is located below the roller 3, and the two ends of the roller 3 are rotatably mounted on the two ends of the roller frame 4, thereby enabling the roller 3 to roll. In addition, a rotating shaft is provided at the middle position of the bottom of the roller frame 4. Correspondingly, a circular hole is provided on the support seat 2 of the support mechanism, and the rotating shaft at the bottom of the roller frame 4 is installed in the circular hole, thereby increasing the degree of freedom of the roller assembly and facilitating the swing of the roller assembly relative to the support mechanism.

[0023] like Figure 2 As shown, roller brackets 5 are installed near both ends of the support mechanism. Correspondingly, rollers are installed at the bottom of the roller assembly near both ends. The rollers are located above the roller brackets 5. Therefore, during the swing of the roller assembly, the roller brackets 5 can be supported below the rollers. The rolling of the rollers relative to the roller brackets 5 can make the swing of the roller assembly more stable. In addition, a mounting post 6 is fixed to the side of the support mechanism near one end. The mounting post 6 is arranged horizontally along the direction of belt extension. One end of the cylinder 7 is hinged to the mounting post 6, and the other end of the cylinder 7 is hinged to one side of the roller bracket 4. Therefore, by controlling the extension and contraction of the cylinder 7, the swing of the roller assembly can be achieved, thereby achieving belt deviation correction.

[0024] like Figure 2 As shown, vertical plates 8 are installed at both ends of the support mechanism, and horizontal brackets 9 are installed at the lower parts of the two vertical plates 8. Two detection and driving mechanisms are respectively installed at the ends of the two horizontal brackets 9. In this way, the two detection and driving mechanisms can be located on both sides of the belt, so as to facilitate bidirectional deviation correction of the belt. Specifically, the detection and driving mechanism includes a deviation correction detection wheel 10, a deviation correction oil pump 11 and an oil storage box. The deviation correction detection wheel 10 is located above the deviation correction oil pump 11, and the oil storage box is connected to the deviation correction oil pump 11, and the deviation correction oil pump 11 is connected to the oil cylinder 7 through an oil pipe. An oil pump mounting plate 14 is fixed to one side of the deviation correction oil pump 11, and the oil pump mounting plate 14 is installed at one end of the horizontal bracket 9. Among them, the detection and driving mechanism is a prior art, and those skilled in the art are familiar with it, so it will not be described in detail.

[0025] In this embodiment, the end of the transverse bracket 9 for mounting the detection and driving mechanism is also fixed with a channel steel 13. The channel steel 13 can realize the reliable installation of the transverse bracket. Figure 3As shown, the notch of the channel steel 13 faces upward, and the bottom of the oil pump mounting plate 14 is rotatably mounted in the notch at one end of the channel steel 13. A fixing plate 15 is vertically fixed to one side of the oil pump mounting plate 14, and both sides of the fixing plate 15 are respectively connected to the two flanges of the channel steel 13. Specifically, both flanges of the channel steel 13 are hinged with swing pins 16, and the outer periphery of the swing pins 16 is also embedded with springs 17. Correspondingly, strip holes are provided on both sides of the fixing plate 15. The upper ends of the two swing pins 16 pass through the strip holes on both sides of the fixing plate and nuts are installed thereafter. The springs 17 abut against the bottom of the fixing plate 15. Therefore, when the belt deviates, the detection and drive mechanism can buffer and avoid to the side to avoid direct impact of the belt, thereby reducing wear on the belt edge and the detection and drive mechanism and extending the service life.
