Description

Technical Field

[0001] This utility model relates to the field of belt conveyor turning devices, and in particular to a novel belt conveyor head and tail turning device. Background Technology

[0002] Tubular belt conveyors (referred to as tube conveyors) are advanced material conveying systems that achieve closed, environmentally friendly, and spatially curved conveying by rolling the conveyor belt into a circular tube. They are beneficial for solving the problems of dust pollution and terrain limitations of traditional conveying methods.

[0003] When the transport route of a tubular belt conveyor changes, such as after the transition between the transport section and the return section, the transport direction of the conveyor belt will change, and the orientation of the overlapping joints of the conveyor belt will also change. For example, Chinese invention application No. 202310407522.2 describes a track-mounted tubular belt conveyor with a locking car, including guide rails, window-type idlers, a locking device, an unlocking device, a locking car, and rollers. The conveyor belt moves along the guide rails and rollers, and the locking car moves along the guide rails. The conveyor belt passes sequentially through the window-type idlers and the locking car. The window-type idlers constrain the conveyor belt into a circular tube shape. The locking car is equipped with a locking device, and the unlocking device and the locking device control the opening and closing of the locking device, thereby controlling the shape of the conveyor belt. The locking car of this invention can independently achieve the function of wrapping around the conveyor belt into a circular tube shape, thus supporting the conveyor belt.

[0004] When the conveyor belt of this application travels from the transport section around the head roller to the return section, its transport direction changes. At this time, the transport surface (working surface) of the conveyor belt will be vertically downward and will gradually curl downward, forming a conveyor belt with the overlap facing downward. When the overlap of the conveyor belt is downward, it will be easy to open up, and the conveyor belt will not easily form a perfect circular structure. The conveyor belt will collapse during operation, affecting the normal operation of the conveyor. At the same time, the conveyor belt will remain in a state with the overlap facing downward for a long time in the return section, and the structure of the conveyor belt itself will be deformed, which is not conducive to reforming the perfect circular tubular structure with the overlap facing upward in the transport section. Utility Model Content

[0005] To overcome the problem mentioned above that the conveyor belt cannot maintain its overlap facing upwards when the transport route changes, which would affect the structure of the conveyor belt, this utility model provides a novel head and tail turning device for belt conveyors. Through the setting of pressure rollers, the conveyor belt can be turned from a horizontal arrangement to a vertical arrangement. The conveyor belt can maintain its overlap facing upwards throughout the entire process. It has the advantages of simple and ingenious structure, easy conveyor belt turning, no impact on the structure of the conveyor belt, and convenient and stable transition between the upper and lower rails for the locking car via wheel and rail.

[0006] The technical solution of this utility model is as follows: A novel belt conveyor head and tail reversing device includes a locking car and a frame body, and also includes several pressure rollers arranged on the frame body. The pressure rollers are arranged vertically, and the conveyor belt passes around each pressure roller in sequence. The frame body is also equipped with wheel rails, and the locking car travels and turns along the wheel rails.

[0007] Compared with existing technologies, the beneficial effects of this technical solution are as follows: This overturning device, through the installation of pressure rollers, enables the conveyor belt to be flipped from a horizontal arrangement to a vertical arrangement. It assists the conveyor belt in completing the entire process of flipping from a horizontal plane to a vertical plane and then back to a horizontal plane at the head and tail of the tube machine. At the same time, the locking car can also transition between the upper and lower rails via wheel-rail, and ensures that the overlap formed by the conveyor belt faces upward throughout the entire process. This avoids the collapse of the conveyor belt when the overlap faces downward in the return section, which would affect the normal operation of the conveyor and cause deformation of the conveyor belt's own structure. It is not conducive to reforming the perfectly circular tubular structure with the overlap facing upward in the transport section. It has the advantages of simple and ingenious structure, easy belt flipping, no impact on the structure of the conveyor belt, and convenient and stable transition of the locking car between the upper and lower rails via wheel-rail.

[0008] Preferably, the pressure rollers are arranged on both sides of the frame, and the conveyor belt passes around the pressure rollers on both sides of the frame in sequence.

[0009] Its beneficial effect is that this arrangement of pressure rollers allows the conveyor belt to transition more naturally and smoothly to another conveyor line after it is flipped into a vertical arrangement.

[0011] Its beneficial effects are: the horizontal and vertical bars in the frame are used to fix and install the pressure rollers and wheel rails.

[0012] More preferably, each of the crossbars on both sides of the frame is provided with two pressure rollers, with the two pressure rollers on each side being arranged on the inner and outer sides of the crossbar respectively; the conveyor belt passes between the two pressure rollers on each side.

[0013] Its beneficial effects are as follows: the pressure rollers on both sides of the frame can guide the conveyor belt, and this structure and arrangement are more conducive to the stability of the conveyor belt during the turning process of horizontal and vertical arrangement. The conveyor belt passes through the two pressure rollers on each side in sequence, which allows the conveyor belt to pass smoothly through the frame without problems such as curling or misalignment.

[0014] More preferably, a pressure roller is arranged at each end of the crossbar on the front side of the frame body, the two pressure rollers are located on the same side of the crossbar, and the conveyor belt passes over the outer roller surface of the two pressure rollers.

[0015] Its beneficial effects are: the pressure rollers on the front side of the frame guide the conveyor belt and allow the conveyor belt to pass around the frame more smoothly.

[0016] Preferably, the wheel rail is a vertically arranged arc-shaped structure, with the upper part of the wheel rail connected to the upper rail on which the locking vehicle travels, and the lower part connected to the lower rail on which the locking vehicle travels, and the locking vehicle transitions between the upper and lower rails along the wheel rail.

[0017] Its advantages are that the locking car can move from the upper rail to the lower rail or from the lower rail to the upper rail along the wheel rail. This wheel rail configuration facilitates the transition of the locking car between the upper and lower rails.

[0018] More preferably, the bottom of the locking car is fixed with a traction rope, and the locking car travels on the upper rail, wheel rail and lower rail under the traction of the traction rope.

[0019] Its beneficial effects are that the traction rope can traction the locking car so that it can travel stably on the upper rail, wheel rail and lower rail, and will not derail.

The U-bolts are fixed on the support frame, and the traction rope passes through the U-bolts and is clamped inside the U-bolts.

[0021] Its beneficial effects are as follows: by fixing the traction rope to the support frame with U-bolts, the traction rope and the locking car can be kept in a stable connection state, and the traction rope can stably drive the locking car to move.

[0022] In a further preferred embodiment, the frame body also has several rotating wheels arranged along the wheel rail extension direction, and the traction rope is wound around the surface of the rotating wheels.

[0023] Its beneficial effect is that the traction rope is wound around the surface of the slewing wheel, and multiple slewing wheels work together to guide the traction rope.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example 1: As Figures 1 to 2 The present invention discloses a novel belt conveyor head and tail reversing device, comprising a locking car 1 and a frame body 2. The locking car 1 is a related structure in the prior art, mainly comprising a locking arm 14 and a locking device 15. When the locking arm 14 is in the closed state, the locking device 15 is closed, fixing the position and state of the locking arm 14, thereby maintaining the circular tube shape of the conveyor belt 6. When the locking device 15 is open and the locking arm 14 is in the open state, the conveyor belt 6 unfolds from the circular tube shape to the trough shape, making it convenient for the conveyor belt 6 to detach from the locking car 1. The locking car 1 itself can independently achieve the function of supporting the conveyor belt 6 by wrapping around the conveyor belt 6 in a circular tube shape.

[0030] It also includes several pressure rollers 4 arranged vertically on the frame body 2. The conveyor belt 6 passes around each pressure roller 4 in sequence. The conveyor belt 6, which extends horizontally, gradually flips in the vertical direction after passing the rollers. After reaching the pressure roller 4, it passes over the surface of the pressure roller 4. The transport surface of the conveyor belt 6 at the pressure roller 4 position faces the outside of the frame body 2. After passing all the pressure rollers 4, the conveyor belt 6 gradually flips in the same direction to be arranged horizontally, and then reaches the locking car 1 and is rolled upward into a tubular structure, keeping the overlapping joint facing upward. The frame body 2 is also equipped with a wheel rail 3. The locking car 1 travels along the wheel rail 3 and turns. The locking car 1 can travel from the upper rail 61 along the wheel rail 3 to the lower rail 62 or from the lower rail 62 along the wheel rail 3 to the upper rail 61.

[0031] This overturning device can be installed at any position in the entire conveyor where overturning is required. In this embodiment, the overturning device is installed at the head and tail of the conveyor. After the conveyor belt 6 passes the tail roller, it gradually overturns in the vertical direction. The overturning direction needs to ensure that the transport surface faces outward when it reaches the vertically arranged position of the frame body 2. At the same time, the locking car 1 moves from the upper rail 61 of the transport section along the wheel rail 3 to the lower rail 62 of the return section. After the conveyor belt 6 passes around the frame body 2, it gradually overturns in the horizontal direction. The overturning direction needs to ensure that the transport surface faces upward when the conveyor belt 6 is horizontally arranged. When the conveyor belt 6 reaches the locking car 1 of the return section, it is rolled upward into a tubular structure. Then, after reaching the head roller, it is overturned in the same way. At the same time, the locking car 1 moves from the lower rail 62 of the return section along the wheel rail 3 to the upper rail 61 of the transport section. After the conveyor belt 6 reaches the locking car 1 of the transport section, it is also rolled upward into a tubular structure. The conveyor belt 6 can form an overlap with the entire length facing upward. In addition, when this overturning device is installed in other positions on the conveyor, the tilt angle of the pressure roller 4 can be adjusted according to actual needs to achieve the overturning of the conveyor belt 6 at different angles.

[0032] Therefore, this overturning device, through the pressure roller 4, enables the conveyor belt 6 to be overturned from a horizontal arrangement to a vertical arrangement, assisting the conveyor belt 6 in completing the entire process of overturning from a horizontal plane to a vertical plane and then back to a horizontal plane at the head and tail of the tube machine. At the same time, the locking car 1 can also transition between the upper rail 61 and the lower rail 62 via the wheel rail 3, and achieves that the overlap formed by the conveyor belt 6 faces upward throughout the entire process. This avoids the situation in the prior art where the conveyor belt 6 collapses when the overlap faces downward in the return section, affecting the normal operation of the conveyor and causing deformation of the conveyor belt 6's own structure. This is not conducive to reforming the upright circular tubular structure with the overlap facing upward in the transportation section. It has the beneficial effects of simple and ingenious structure, easy overturning of the conveyor belt, no impact on the structure of the conveyor belt 6, and convenient and stable transition of the locking car 1 between the upper and lower rails 62 via the wheel rail 3.

[0033] Example 2: Based on Example 1, the pressure rollers 4 are optimized. The pressure rollers 4 are arranged on both sides of the frame 2, forming a U-shape. The conveyor belt 6 passes around the pressure rollers 4 on both sides of the frame 2 in sequence; that is, the conveyor belt 6 enters from the pressure roller 4 on one side of the frame 2 and exits from the pressure roller 4 on the other side. This arrangement of the pressure rollers 4 allows the conveyor belt 6 to transition more naturally and smoothly to another conveying line after it is flipped into a vertical arrangement.

[0034] The frame body 2 is a frame structure, including fixed connecting horizontal bars 21 and vertical bars 22. The pressure roller 4 is fixed to the horizontal bars 21 by bolts. That is, the upper and lower ends of the roller shaft of the pressure roller 4 are vertically fixed to the horizontal bars 21 located at the upper and lower parts by bolts, respectively. When the conveyor belt 6 passes over the pressure roller 4, the pressure roller 4 can rotate. The horizontal bars 21 and vertical bars 22 in the frame body 2 are used to fix the pressure roller 4 and the wheel rail 3. The wheel rail 3 is installed inside the frame, and the pressure roller 4 is arranged around the frame body 2.

[0035] Preferably, two pressure rollers 4 are arranged on each of the crossbars 21 on both sides of the frame 2, with the two pressure rollers 4 on each side arranged on the inner and outer sides of the crossbar 21, respectively; the conveyor belt 6 passes through the two pressure rollers 4 on each side in sequence. The pressure rollers 4 on both sides of the frame 2 can guide the conveyor belt 6, and this structure and arrangement are more conducive to the stability of the conveyor belt 6 during the turning process of horizontal and vertical arrangement. Furthermore, the fact that the conveyor belt 6 passes through the two pressure rollers 4 on each side in sequence allows the conveyor belt 6 to pass smoothly through the frame 2 without problems such as curling or misalignment. In a further preferred embodiment, a pressure roller 4 is arranged at each end of the crossbar 21 on the front side of the frame 2. The front side of the frame 2 is the side between the two sides of the frame 2 and through which the conveyor belt 6 passes. The two pressure rollers 4 are located on the same side of the crossbar 21, that is, on the outer or inner side of the crossbar 21. In this embodiment, the pressure rollers 4 are installed on the outer side of the crossbar 21, and the conveyor belt 6 passes over the outer roller surfaces of the two pressure rollers 4. The pressure rollers 4 on the front side of the frame 2 guide the conveyor belt 6 and allow the conveyor belt 6 to pass over the frame more smoothly.

[0036] Example 3: Based on Example 1, the wheel rail 3 is optimized. The wheel rail 3 is a vertically arranged arc structure that protrudes away from the upper rail 61 and the lower rail 62. The upper rail 61 is the track for the interlocking car 1 in the transport section of the pipeline machine, and the lower rail 62 is the track for the interlocking car 1 in the return section. The upper part of wheel rail 3 is connected to the upper rail 61 on which the locking car 1 travels, and the lower part is connected to the lower rail 62 on which the locking car 1 travels. The ends of the upper rail 61 and the lower rail 62 are fixedly connected to the upper crossbar 21 and the lower crossbar 21 on the frame body 2, respectively. The upper and lower ends of wheel rail 3 are also fixedly connected to the upper crossbar 21 and the lower crossbar 21 on the frame body 2, respectively. The top and lower parts of the two single rails of wheel rail 3 are on the extension lines of the upper rail 61 and the lower rail 62, respectively. Thus, wheel rail 3 is connected to the upper rail 61 and the lower rail 62 through the frame body 2. The locking car 1 can travel along wheel rail 3 from the upper rail 61 to the lower rail 62 or from the lower rail 62 to the upper rail 61. This arrangement of wheel rail 3 facilitates the transition of the locking car 1 between the upper rail 61 and the lower rail 62.

[0037] Preferably, the bottom of the locking car 1 is fixed with a traction rope 11. Under the traction of the traction rope 11, the locking car 1 travels on the upper rail 61, the wheel rail 3, and the lower rail 62. The traction rope 11 moves at the same speed as the conveyor belt 6. The conveyor belt 6 and the traction rope 11 can drive the locking car 1 to travel stably on the upper rail 61 and the lower rail 62. When the locking car 1 passes the wheel rail 3, it will disengage from the conveyor belt 6. At this time, the traction rope 11 will drive the locking car 1 to slide on the wheel rail 3 alone. The traction rope 11 can traction the locking car 1 so that it can travel stably on the upper rail 61, the wheel rail 3, and the lower rail 62 without derailment.

[0038] Specifically, the traction rope 11 is made of steel wire rope, such as... Figure 2 As shown, the traction rope 11 is connected to the support frame 13 at the bottom of the locking vehicle 1 by a U-bolt 12. The U-bolt 12 is fixedly connected to the support frame 13 by a nut. The traction rope 11 passes through the U-bolt 12 and is clamped inside the U-bolt 12. The U-bolt 12 can provide a strong clamping force. By fixing the traction rope 11 to the support frame 13 by the U-bolt 12, the traction rope 11 and the locking vehicle 1 can maintain a stable connection. The traction rope 11 can stably drive the locking vehicle 1 to move.

[0039] Preferably, the frame body 2 is also fixed with a number of rotating wheels 5 arranged along the extension direction of the wheel rail 3. The rotating wheels 5 are arranged horizontally inside the frame body 2 and located below the inner annular surface of the wheel rail 3, and are fixed on the horizontal bar 21 or the vertical bar 22. The traction rope 11 is wound around the surface of the rotating wheel 5, and the multiple rotating wheels 5 work together to guide the traction rope 11.

[0040] Specifically, the rotary wheel 5 includes a central shaft 53 and a wheel body 51 sleeved around the circumference of the central shaft 53. The wheel body 51 is connected to the central shaft 53 by a bearing and can rotate around the central shaft 53. The wheel body 51 has a hollow structure with several openings 52. The openings 52 can reduce the mass of the rotary wheel 5. This type of rotary wheel 5 is a small rotary wheel 5. Multiple small rotary wheels 5 are installed together in the frame body 2. The traction rope 11 slides on the surface of the wheel body 51, which can stably guide the traction rope 11.

[0041] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
