Description

Technical Field

[0001] This invention relates to the field of slope protection material transportation technology, and in particular to a slope protection material transportation device. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Hexagonal slope protection blocks are a type of building material commonly used in slope protection projects. Due to their unique hexagonal structure, they have good stability and protective performance. They are widely used for slope protection of rivers, reservoirs, dikes, road cuts, etc., and can effectively prevent soil erosion on river slopes.

[0004] When laying hexagonal blocks, they are usually first unloaded at the bottom of the slope by transport equipment, and then workers carry the hexagonal blocks one by one to the slope for laying. Since the slope has a certain gradient and is usually 6-10 meters high, only one block can be carried manually at a time, which requires a lot of manpower and resources and has low work efficiency. There is room for improvement. Therefore, this application proposes a slope protection material transportation device to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a slope protection material conveying device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A slope protection material conveying device includes:

[0008] The guide rail can be placed on the slope surface from bottom to top;

[0009] A support tray with rollers at its bottom that are adapted to guide rails, the support tray being used to support materials;

[0010] A winch is located at one end of the top of the corresponding slope of the guide rail. The rope on the winch is connected to the bearing plate, which pulls the bearing plate to move on the guide rail.

[0011] Furthermore, the guide rail includes a first slide rail and a second slide rail with a frame structure. One end of the second slide rail is slidably disposed within the first slide rail and can slide along the length direction of the first slide rail. It also includes a limiting member for limiting the relative position of the first slide rail and the second slide rail.

[0012] Furthermore, the bottom of the guide rail has multiple casters, each caster having an extended state and a retracted state; in the extended state, the bottom of each caster can extend below the guide rail, so that the bottom surface of the guide rail does not contact the slope; in the retracted state, the bottom of each caster does not extend beyond the bottom surface of the guide rail, so that the bottom surface of the guide rail contacts the slope.

[0013] Furthermore, it also includes a winding wheel located at the same end of the guide rail as the winch, with a winding rope wound around the winding wheel, one end of which is fixed to the winding wheel;

[0014] By fixing the other end of the winding rope to the top of the slope and starting the winding wheel to wind up the winding rope, the guide rail or the second slide rail is moved towards the top of the slope.

[0015] It also includes a power unit to drive the winding reel to rotate.

[0016] Furthermore, multiple casters are distributed at both ends of the guide rail, including a first caster located at the top end of the corresponding slope of the guide rail and a second caster located at the bottom end of the corresponding slope of the guide rail;

[0017] The first caster is provided in multiple ways, and the top of the multiple first casters is connected to a lifting plate. The lifting plate can move up and down in the guide rail, driving the bottom of the multiple first casters into the interior of the guide rail and extending to the bottom of the guide rail. The system also includes a pushing mechanism, which is provided on both sides of the winding wheel. When the winding wheel rotates, the lifting plate is pushed down, so that the bottom of the multiple first casters extends to the bottom of the guide rail and locks the position of the lifting plate relative to the guide rail.

[0018] The second caster is provided in multiple ways, and the top of the multiple second casters is connected to a rotating plate. The rotating plate is rotatably mounted on the guide rail. The rotating plate can drive the multiple second casters to rotate from a vertical position to a horizontal position. The second casters in the horizontal position are located on the side of the guide rail, and the bottom of the second casters in the vertical position extends to below the guide rail.

[0019] One side of the rotating plate is provided with a traction ring for connecting to the winding rope. By pulling the traction ring with the winding rope, the rotating plate can be rotated, causing the second caster to rotate from a horizontal position to a vertical position.

[0020] Furthermore, a stop is provided on the guide rail, and after the second caster rotates to a vertical position, the stop prevents the rotating plate from continuing to rotate.

[0021] Furthermore, the jacking mechanism includes an eccentric cam and a worm gear, which are coaxially arranged. It also includes a transmission assembly, which is connected to the rotating shaft of the take-up reel and drives the eccentric cam and worm gear to rotate synchronously when the take-up reel rotates.

[0022] The eccentric cam is located above the lifting plate, and the guide rail is provided with a clearance groove at the position of the eccentric cam. The rotation of the eccentric cam can push the lifting plate downward.

[0023] A sliding rod is provided at the top of the lifting plate at the position corresponding to the worm gear. The top of the sliding rod extends upward to above the guide rail. A sleeve is rotatably provided at the guide rail at the position corresponding to the sliding rod. The sliding rod is slidably sleeved inside the sleeve. A guide groove is provided on the inner wall of the sleeve. The guide groove includes a vertical first groove section. The bottom of the first groove section is provided with a second groove section spiraling downward along the arc-shaped inner wall of the sleeve. The end of the second groove section is provided with a horizontal third groove section. The first, second, and third groove sections are connected in sequence. A slider is provided on the sliding rod to slide in cooperation with the guide groove. A worm wheel is provided at the top of the sleeve. The worm wheel is used to cooperate with the worm gear. The worm wheel has a notch, and in the initial state, the notch faces the worm gear. In this state, the worm wheel and the worm gear are disengaged.

[0024] When the take-up reel rotates, the transmission assembly drives the eccentric cam and worm gear to rotate synchronously. The eccentric cam pushes the lifting plate downward, causing the lifting plate and slide bar to move downward relative to the guide rail. The slide bar moves downward, and the slider on it enters the second groove, forcing the sleeve to rotate so that its worm wheel meshes with the worm gear. Driven by the worm gear, the slide bar continues to drive the lifting plate downward until the slider enters the third groove. Then, the notch on the worm wheel rotates back to the worm gear.

[0025] Furthermore, the take-up reel's rotating shaft extends out of the take-up reel and is connected to a first gear at both ends. The transmission assembly includes a second gear meshing with the first gear. The second gear, the eccentric cam, and the worm gear are coaxially connected together via a first connecting shaft. The power component is used to drive the first connecting shaft to rotate.

[0026] Furthermore, a support frame is provided at one end of the corresponding winch of the guide rail, the winch is located at the top of the support frame, the winding wheel is located below the support frame, and the power component includes a first transmission wheel arranged on the winch shaft, a second transmission wheel arranged below the support frame and on the same axis as the first connecting shaft, and a transmission belt connecting the first transmission wheel and the second transmission wheel;

[0027] A second connecting shaft is rotatably mounted on the guide rail. A second transmission wheel is mounted on the second connecting shaft to drive the second connecting shaft to rotate. The second connecting shaft is hollow inside, corresponding to one end of the first connecting shaft. One end of the first connecting shaft is inserted into the interior of the second connecting shaft. A screw passes through the first and second connecting shafts from the side to connect the first and second connecting shafts together. After the screw is removed, the first and second connecting shafts can rotate independently.

[0028] Furthermore, it also includes bumps, of which multiple bumps are provided and distributed at the bottom of the guide rail.

[0029] The beneficial effects of this invention are reflected in:

[0030] This application, by placing the material at the bottom of the slope on a carrying plate and then activating a winch, uses ropes on the winch to pull the carrying plate along a guide rail to deliver the material to a designated area on the slope, can greatly reduce the labor intensity of workers and has high work efficiency.

[0039] 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 a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0040] like Figure 1-6 As shown, the present invention discloses a slope protection material conveying device, comprising:

[0041] Guide rail 1 can be placed on the slope surface from bottom to top;

[0042] The support plate 2 has rollers (not shown in the figure) at its bottom that are adapted to the guide rail 1. The support plate 2 is used to support materials.

[0043] The winch 3 is located at one end of the corresponding slope top of the guide rail 1. The rope 31 on the winch 3 is connected to the bearing plate 2, which pulls the bearing plate 2 to move on the guide rail 1.

[0044] In practice, workers place the guide rail 1 on the slope surface from bottom to top, then place the material (such as hexagonal blocks) at the bottom of the slope onto the support plate 2. The winch 3 is then activated, and the rope 31 on the winch 3 pulls the support plate 2 along the guide rail 1, delivering the material to the designated area on the slope. This significantly reduces the labor intensity of workers and increases work efficiency. Because the slope is inclined, when the support plate 2 is reset, the rope 31 can be released directly through the winch 3, and the support plate 2 will automatically move to the bottom of the slope under gravity.

[0045] It should be noted that outdoor construction sites are often equipped with outdoor power sources (such as diesel generators, gasoline generators, etc.), and the winch 3 can draw power directly from the outdoor power source.

[0046] In one embodiment, the guide rail 1 includes a first slide rail 11 and a second slide rail 12 with a frame structure. One end of the second slide rail 12 is slidably disposed within the first slide rail 11, allowing it to slide along the length of the first slide rail 11 to adjust the overall length of the guide rail 1. It also includes a limiting member to limit the relative position of the first slide rail 11 and the second slide rail 12. This design allows it to adapt to slopes with varying widths and facilitates storage. Since the winch 3 is located at the end of the guide rail 1 furthest from the bottom of the slope, changes in the overall length of the guide rail 1 will not affect the normal operation of the winch 3 or the support disc 2.

[0047] Preferably, both the first slide rail 11 and the second slide rail 12 include two C-shaped steels arranged on the left and right sides, with the openings of the C-shaped steels facing upwards. The inner sides of the two ends of the two C-shaped steels are connected by a connecting rod. A groove is passed through the two C-shaped steels facing each other in the first slide rail 11. The connecting rod at one end of the second slide rail 12 passes through the groove and slides in cooperation with the groove.

[0048] Preferably, the limiting member includes multiple screw holes formed on one side of the first slide rail 11. By rotating a suitable bolt within the screw holes and tightening the bolt, the end of the bolt can be pressed against the side wall of the second slide rail 12, thereby limiting the relative position of the first slide rail 11 and the second slide rail 12. Of course, the second slide rail 12 can also be provided with a row of multiple blind holes adapted to the bolt. Tightening the bolt causes the end of the bolt to extend into the blind hole, thereby limiting the relative position of the first slide rail 11 and the second slide rail 12.

[0049] In one embodiment, the bottom of the guide rail 1 has multiple casters, each caster having an extended state and a retracted state; in the extended state, the bottom of each caster can extend below the guide rail 1, so that the bottom surface of the guide rail 1 does not contact the slope; in the retracted state, the bottom of each caster can not extend beyond the bottom surface of the guide rail 1, so that the bottom surface of the guide rail 1 contacts the slope.

[0050] In practice, when the slope on one side of the guide rail 1 is laid, the bottom of the caster can be extended under the guide rail 1 so that the bottom surface of the guide rail 1 does not contact the slope. Then, the guide rail 1 can be manually pushed along the length of the slope to the predetermined position. After that, the caster is returned to the retracted state so that the bottom surface of the guide rail 1 contacts the slope again, thus completing the transfer of the guide rail 1.

[0051] Preferably, the caster is a swivel caster.

[0052] In one embodiment, a winding wheel 4 is also included at the same end of the guide rail 1 as the winch 3. A winding rope 41 is wound on the winding wheel 4. One end of the winding rope 41 is fixed to the winding wheel 4, and the other end of the winding rope 41 can extend to the top of the slope.

[0053] By fixing the other end of the winding rope 41 to the top of the slope and starting the winding wheel 4 to wind up the winding rope 41, the guide rail 1 or the second slide rail 12 is moved towards the top of the slope.

[0054] It also includes a power component to drive the winding reel 4 to rotate.

[0055] In practice, the power component is a motor, which drives the winding wheel 4 to work. When it is necessary to adjust the guide rail 1 as a whole to the top of the slope or to extend the second slide rail 12, the bottom of the caster can be extended below the guide rail 1 so that the bottom surface of the guide rail 1 at the top of the slope does not contact the slope surface. Then, the other end of the winding rope 41 is fixed to the top of the slope (the winding rope 41 can be tied to the corresponding fixed object. If there is no fixed object, it can be fixed by inserting a stake into the ground). Then, the motor is started. Under the action of the reaction force, the guide rail 1 as a whole or the second slide rail 12 will automatically move upward to the top of the slope. After moving to the designated position, the caster is retracted so that the guide rail 1 contacts the slope surface. Then, the other end of the winding rope 41 is fixed, and the adjustment of the guide rail 1 is completed.

[0056] It should be noted that when the second slide rail 12 slides into the first slide rail 11 to shorten the overall length of the guide rail 1, after the bottom of the caster extends below the guide rail 1 and the limiting member is released, on the one hand, the second slide rail 12 can automatically slide into the first slide rail 11 under the action of gravity, and on the other hand, the other end of the winding rope 41 can be fixed on the first slide rail 11, and then the movement of the second slide rail 12 is assisted by winding the winding rope 41.

[0057] It should be noted that the motor used as the power component can be a conventional motor. However, conventional motors do not have a shaft locking function. Once the motor stops working, the winding wheel 4 is prone to reverse rotation. Therefore, a worker needs to assist from one side to prevent the entire guide rail 1 or the second slide rail 12 from moving to the bottom of the slope. Therefore, the motor used as the power component in this application is preferably a motor with a shaft locking function, such as a servo motor equipped with a mechanical brake device. Of course, some servo motors themselves have a shaft locking function. Since motors with a shaft locking function are existing technology, they will not be described in detail here.

[0058] In one embodiment, the caster can be a lift-type caster as in the prior art, but such casters have a complex structure and are somewhat complicated to use. Therefore, the caster of this application adopts the following structural form:

[0059] Multiple casters are distributed at both ends of the guide rail 1, including a first caster 13 located at the top end of the corresponding slope of the guide rail 1 and a second caster 14 located at the bottom end of the corresponding slope of the guide rail 1;

[0060] The first caster 13 is provided in multiple ways, and the top of the multiple first casters 13 is connected to a lifting plate 15. The lifting plate 15 can move up and down in the guide rail 1, driving the bottom of the multiple first casters 13 into the interior of the guide rail 1 and extending to the bottom of the guide rail 1. The system also includes a jacking mechanism 5, which is provided on both sides of the winding wheel 4. When the power component is started and drives the winding wheel 4 to rotate, the lifting plate 15 is jacked down, so that the bottom of the multiple first casters 13 extends to the bottom of the guide rail 1 and locks the position of the lifting plate 15 relative to the corresponding end of the guide rail 1.

[0061] Multiple second casters 14 are provided, and the top of multiple second casters 14 are connected to a rotating plate 16. The rotating plate 16 is rotatably mounted on the guide rail 1. The rotating plate 16 can drive multiple second casters 14 to rotate from a vertical posture to a horizontal posture. The second casters 14 in the horizontal posture are located on the side of the guide rail 1, and the bottom of the second casters 14 in the vertical posture extends to below the guide rail 1.

[0062] One side of the rotating plate 16 is provided with a traction ring 161 for connecting to the winding rope 41. By traction of the traction ring 161 by the winding rope 41, the rotating plate 16 can be rotated, so that the second caster 14 can be rotated from a horizontal position to a vertical position.

[0063] In practice, when it is necessary to adjust the guide rail 1 as a whole to the top of the slope or to extend the second slide rail 12, after the other end of the winding rope 41 is fixed, the power unit is started to drive the winding wheel 4 to rotate. At this time, the jacking mechanism 5 moves together (the winding rope 41 is in a slack state in the initial test state, with a certain amount of margin for the jacking mechanism 5 to start), pushing the lifting plate 15 downward, so that the bottom of the multiple first casters 13 extends to the bottom of the guide rail 1 and locks the position of the lifting plate 15 relative to the corresponding end of the guide rail 1. At this time, the bottom surface of the guide rail 1 at the corresponding top of the slope does not contact the slope surface. As the winding rope 41 continues to wind, under the action of the reaction force, the guide rail 1 as a whole or the second slide rail 12 will move upward to the top of the slope.

[0064] When it is necessary to push the guide rail 1 along the length of the slope, the other end of the winding rope 41 can be connected to the traction ring 161. By pulling the traction ring 161 through the winding rope 41, the rotating plate 16 can be rotated, causing the second caster 14 to rotate from a horizontal position to a vertical position. At the same time, the jacking mechanism 5 is activated, causing the bottom of the first caster 13 to extend below the guide rail 1. At this time, the worker can push the guide rail 1 along the length of the slope.

[0065] It should be noted that, in order to ensure that the second caster 14 can rotate to a vertical position, a stop 17 can be fixed on the guide rail 1. After the second caster 14 rotates to a vertical position, the stop 17 prevents the rotating plate 16 from continuing to rotate. Since the motors have overload protection functions, after the stop 17 prevents the rotating plate 16 from continuing to rotate, the motor stops rotating under the overload protection function. Alternatively, a trigger switch can be set on the stop 17. After the second caster 14 rotates to a vertical position, the trigger switch is triggered. The trigger switch is connected to the motor circuit, and after being triggered, the motor stops rotating.

[0066] In one embodiment, the jacking mechanism 5 includes an eccentric cam 51 and a worm gear 52, which are coaxially arranged. It also includes a transmission assembly that is connected to the rotating shaft of the take-up reel 4 and synchronously drives the eccentric cam 51 and the worm gear 52 to rotate when the take-up reel 4 rotates.

[0067] The eccentric cam 51 is located above the lifting plate 15. The guide rail 1 is provided with a clearance groove 121 at the position of the eccentric cam 51. The rotation of the eccentric cam 51 can push the lifting plate 15 downward.

[0068] A slide rod 151 is provided at the top of the lifting plate 15 at the position corresponding to the worm gear 52. The top of the slide rod 151 extends upward to above the guide rail 1. A sleeve 18 is rotatably provided at the guide rail 1 at the position corresponding to the slide rod 151. The slide rod 151 is slidably sleeved inside the sleeve 18. A guide groove 181 is provided on the inner wall of the sleeve 18. The guide groove 181 includes a vertical first groove section. The bottom of the first groove section is spirally arranged downward along the arc-shaped inner wall of the sleeve 18 as a second groove section. The end is provided with a transverse third groove segment, and the first groove segment, the second groove segment and the third groove segment are connected in sequence. The slide rod 151 is provided with a slider 152 that slides and engages with the guide groove 181. The top of the sleeve 18 is provided with a worm wheel 182, which is used to engage with the worm 52. The worm wheel 182 has a notch, and in the initial state, the notch faces the worm 52. In this state, the worm wheel 182 is disengaged from the worm 52, that is, the worm 52 cannot drive the worm wheel 182 to rotate.

[0069] When the take-up reel 4 is rotating, the transmission assembly drives the eccentric cam 51 and the worm gear 52 to rotate synchronously. The eccentric cam 51 pushes the lifting plate 15 downward, causing the lifting plate 15 and the slide rod 151 to move downward relative to the guide rail 1. The slider 152 on the downward-moving slide rod 151 enters the second groove, forcing the sleeve 18 to rotate so that its worm wheel 182 meshes with the worm gear 52. Driven by the worm gear 52, the slide rod 151 continues to drive the lifting plate 15 downward until the slider 152 enters the third groove. Then, the notch on the worm wheel 182 rotates back to the worm gear 52, causing the worm wheel 182 to disengage from the worm gear 52. At this time, the eccentric cam 51 is not in contact with the lifting plate 15.

[0070] Specifically, the sleeve 18, which is rotatably mounted on the guide rail 1, is positioned in a fixed manner under the drive of the slide rod 151 and the slider 152. It will not easily rotate under the action of external force. Since the sleeve 18 can only rotate relative to the guide rail 1 and cannot move vertically relative to the guide rail 1, the guide rail 1 can drive the lifting plate 15 to move downward through the slide rod 151. The cam push section of the eccentric cam 51 is arc-shaped and has a sufficient arc length. The arc-shaped cam push section coincides with the rotation center of the eccentric cam 51, providing a plateau period during the initial meshing stage of the worm gear 182 and the worm 52, so that the downward distance of the lifting plate 15 is stably maintained within the specified range, thereby enabling the worm gear 182 and the worm 52 to mesh stably.

[0071] During reset, first reverse the winding wheel 4 to wind the winding rope 41. After winding is complete, manually rotate the sleeve 18 in the reverse direction to re-engage the worm gear 182 and the worm 52. Then, start the force component to reverse the winding wheel 4. Then, the slider 152 moves from the third groove to the first groove. After confirming that the eccentric cam 51 is not in contact with the lifting plate 15, the rotation of the winding wheel 4 can be stopped.

[0072] In one embodiment, the two ends of the rotating shaft of the take-up reel 4 extend out of the take-up reel 4 and are connected to the first gear 42. The transmission assembly includes a second gear 53 that meshes with the first gear 42. The second gear 53, the eccentric cam 51 and the worm gear 52 are coaxially connected together through a first connecting shaft 54. The power component is used to drive the first connecting shaft 54 ​​to rotate.

[0073] In one embodiment, although the power component can be a motor as described above, motors with shaft locking function are generally more expensive. Therefore, this application provides the following technical solution to reduce costs:

[0074] The guide rail 1 is provided with a support frame 6 at one end of the corresponding winch 3. The winch 3 is located at the top of the support frame 6, and the winding wheel 4 is located below the support frame 6. The power component includes a first transmission wheel 32 located on the shaft of the winch 3, a second transmission wheel 71 located below the support frame 6 and on the same axis as the first connecting shaft 54, and a transmission belt 8 connecting the first transmission wheel 32 and the second transmission wheel 71.

[0075] A second connecting shaft 7 is rotatably mounted on the guide rail 1. A second transmission wheel 71 is mounted on the second connecting shaft 7 to drive its rotation. The second connecting shaft 7 is hollow, corresponding to one end of the first connecting shaft 54. One end of the first connecting shaft 54 ​​is inserted into the interior of the second connecting shaft 7. A screw 9 passes through the first connecting shaft 54 ​​and the second connecting shaft 7 from the side, connecting them together. After removing the screw 9, the first connecting shaft 54 ​​and the second connecting shaft 7 can rotate independently. This allows the screw 9 to be inserted when the winding reel 4 is in use and removed when not in use. Since the winch 3 has a self-locking property, power is drawn from the winch 3, which saves on a motor and, thanks to its self-locking performance, prevents the winding reel 4 from reversing under gravity.

[0076] The first connecting shaft 54 ​​and the second connecting shaft 7 are round shafts. One end of the screw 9 completely passes through the first connecting shaft 54 ​​and the second connecting shaft 7, and then the other end is screwed in by a nut. Of course, one of the first connecting shaft 54 ​​and the second connecting shaft 7 can be provided with a thread that engages with the screw 9, and the position of the screw 9 can be fixed by screwing in.

[0077] Preferably, the first drive wheel 32 and the second drive wheel 71 can be synchronous pulleys or sprockets, and the drive belt 8 can be a synchronous belt or a chain.

[0078] In one embodiment, a plurality of protrusions 19 are provided and distributed at the bottom of the guide rail 1 to increase the friction between the guide rail 1 and the slope when the guide rail 1 is in contact with the slope, thereby preventing the guide rail 1 from shifting left or right.

[0079] Preferably, after the caster extends out of the guide rail 1, the protrusion 19 will separate from the slope under the action of the guide rail 1.
