Description

Technical Field

[0001] The present invention relates to the technical field of material transportation equipment, and particularly relates to a mechanical material feeding system for cableway transportation of transmission lines. Background Art

[0002] Many power grid construction projects are located in mountainous areas with complex terrains, where the transportation of materials such as large tower materials, conductors, and equipment is very difficult. Traditional transportation methods such as building roads through mountains, using mules and horses, vehicles, or manual labor are not only inefficient but also costly, and may cause damage to the environment. For this reason, many power projects have temporarily built detour material transportation cableways in such terrains.

[0003] Considering that when using a detour cableway for transportation, it is necessary to hang a hanging box with goods on the hook of the cableway and remove the empty hanging box on the hook of the cableway and refill it with goods. Manually using a forklift for loading and unloading has problems of being untimely and unsafe, specifically manifested as follows: Although the cableway transportation is slow, it is always in motion. It is not easy for a person to hang the hook with a forklift in a short time, and there is also a risk of the hanging box falling. To better solve this problem, the present application provides a mechanical material feeding system for cableway transportation of transmission lines. Summary of the Invention

[0004] The present invention specifically adopts the following technical solutions to achieve the above object: A mechanical material feeding system for cableway transportation of transmission lines includes a feeding conveyor mechanism arranged below the discharging track of the detour cableway and a loading conveyor mechanism arranged below the loading track of the detour cableway. Both the loading conveyor mechanism and the feeding conveyor mechanism can move vertically up and down to a first position or a second position.

[0005] When the feeding conveyor mechanism is in the first position, it is used to remove the empty hanging box, and when in the second position, it is used to convey the empty hanging box outwards. When the loading conveyor mechanism is in the first position, it is used to hang the full hanging box on the hook, and when in the second position, it is used to obtain other hanging boxes.

[0006] Further, the loading conveyor mechanism includes a first roller conveyor and a second roller conveyor located on the same conveying line, and the second roller conveyor is installed on the ground through legs.

[0007] Further, the feeding conveyor mechanism includes a third roller conveyor and a fourth roller conveyor located on the same conveying line, and the fourth roller conveyor is installed on the ground through legs.

[0008] Further, sliding rods are fixedly installed at the bottoms of the frames of the first roller conveyor and the third roller conveyor. The sliding rods are slidably inserted into the inner parts of the sleeve rods installed on the ground. The ends of the sliding rods are configured with sliding convex parts, and the sliding convex parts are slidably arranged within the sleeve rods.

[0009] Further, cross bars are installed at the bottoms of the frames of the first roller conveyor and the third roller conveyor. A driving mechanism for driving the first roller conveyor and the third roller conveyor to move to the first position or the second position is further included. The driving mechanism includes a base disposed between the first roller conveyor and the third roller conveyor. The base is installed on the ground, and a cantilever with equal lengths on the left and right is rotatably installed thereon. A push rod for pushing the cross bar is fixed at the end of the cantilever. A round rod is fixed between a pair of sleeve rods located on the ground. A hydraulic rod is rotatably installed on the round rod, and the other end of the hydraulic rod is rotatably connected to the cantilever.

[0010] Further, a baffle is provided at the intersection of the horizontal section and the inclined section of the cableway for the first roller conveyor. A material blocking mechanism is also provided between the connection of the first roller conveyor and the second roller conveyor and between the connection of the third roller conveyor and the fourth roller conveyor. The material blocking mechanism is used to prevent the hanging box from detaching from the conveying surface when the first roller conveyor and the third roller conveyor are not in the second position.

[0011] Further, the material blocking mechanism includes a pair of auxiliary rods whose ends are rotatably connected by a shaft rod and a pair of blocking rods whose middle positions are rotatably connected by a shaft rod. The same-direction ends of the two blocking rods are respectively hingedly installed corresponding to the ends of the pair of auxiliary rods. The shaft rod located on the blocking rod is fixed to the side surface of the frame of the second roller conveyor or the third roller conveyor, and the shaft rod located on the auxiliary rod is fixed to the side surface of the frame of the first roller conveyor or the fourth roller conveyor.

[0012] Further, guiding plates are symmetrically fixed to the sides of the conveying surfaces of the first roller conveyor, the second roller conveyor, the third roller conveyor, and the fourth roller conveyor. A plurality of guiding wheels are equidistantly installed on the guiding plates.

[0013] Further, the first roller conveyor, the second roller conveyor, the third roller conveyor, and the fourth roller conveyor are all installed sunk in the ground at the detour cableway, and the conveying surfaces of the second roller conveyor and the fourth roller conveyor are flush with the ground. A fence is provided around the ground outside the first roller conveyor, the second roller conveyor, the third roller conveyor, and the fourth roller conveyor.

[0014] Further, a control panel is provided at the fence. The control panel is electrically connected to the first roller conveyor, the second roller conveyor, the third roller conveyor, the fourth roller conveyor, and the hydraulic pump for controlling the movement of the hydraulic rod.

[0015] The beneficial effects of the present invention are as follows: By designing the base and the cantilever rotatably mounted on the base, the first roller conveyor and the third roller conveyor on the left and right sides can both be used as counterweight structures for each other's lifting and lowering processes during the ascending and descending processes. This greatly reduces the output load of the hydraulic rod. At the same time, when the power hydraulic rod fails, it can also avoid the problem that the goods lose the supporting force and fall heavily on the ground.

[0016] By designing the scissors mechanism composed of the stop rod, the auxiliary rod, and the shaft rod, after the hanging box is removed from the hook, it is conveyed by the third roller conveyor to the position of the stop rod and blocked by the stop rod. It is not until the third roller conveyor descends to the first position and the third roller conveyor is flush with the fourth roller conveyor and the stop rod is retracted that the hanging box can be conveyed, avoiding damage to the goods from falling.

Detailed implementation manners

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] A mechanical method for realizing a material loading system for a transmission line cableway transportation provides a mechanical device for the upper and lower hanging boxes of a detour cableway, and provides the following technical solutions. The following will be combined with Figures 1-9 to make a detailed description: A mechanical method for realizing a material loading system for a transmission line cableway transportation includes a blanking conveying mechanism 1 arranged below the blanking track of the detour cableway and a loading conveying mechanism 2 arranged below the loading track of the detour cableway. The detour cableway is a prior art, and its general structure has been shown in this application. Figure 1 In order to realize loading and unloading, both the loading conveying mechanism 2 and the blanking conveying mechanism 1 can move vertically up and down to the first position 3 or the second position 4. Please refer to Figure 2 , Figure 3 and Figure 4 . Here, the first position 3 refers to the position where the loading conveying mechanism 2 hangs the hanging box on the cableway hook or the height position where the blanking conveying mechanism 1 removes the hanging box from the cableway hook; the second position 4 refers to the position where the loading conveying mechanism 2 or the blanking conveying mechanism 1 returns to the horizontal height.

[0020] Please refer to Figure 2 , Figure 3 . When the blanking conveying mechanism 1 rises to the first position 3, the blanking conveying mechanism 1 raises the height of the hanging box. By setting the traveling speed of the blanking conveying mechanism 1 to be faster than the traveling speed of the cableway (the transmission direction of the blanking conveying mechanism 1 is the same as that of the cableway here), the hanging box can be separated from the hook on the cableway. When the blanking conveying mechanism 1 descends to the second position 4, that is, when it is flush with the ground, the hanging box can be conveyed outwards to be taken away by on-site personnel for reloading goods; Please refer to Figure 4At the same time, the cableway in the prior art has obvious structural characteristics. It has a horizontal section and an inclined section. The hanging box has a change in height when it reaches the inclined section from the horizontal section. Therefore, when the feeding conveying mechanism 2 is in the first position 3, that is, the hanging ring on the hanging box is at a position where the hook of the cableway can be hung, and the position of the hanging box on the feeding conveying mechanism 2 is set to be the intersection of the horizontal section and the inclined section of the cableway. When the hook of the cableway hangs on the hanging box, the hook on the cableway is immediately pulled up from the horizontal section to the height of the inclined section, so that the hanging box hung on the cableway hook follows the rise to separate from the feeding conveying mechanism 2, completing the feeding function.

[0021] like Figures 1 to 5 As shown, in this embodiment, the loading conveying mechanism 2 is composed of a first roller conveyor 201 and a second roller conveyor 202 located on the same conveying line, wherein the second roller conveyor 202 is installed on the ground through legs, and the unloading conveying mechanism 1 is also composed of a third roller conveyor 101 and a fourth roller conveyor 102 located on the same conveying line, and the fourth roller conveyor 102 is also installed on the ground through legs. Here, the loading conveying mechanism 2 and the unloading conveying mechanism 1 are respectively divided into the first roller conveyor 201 and the third roller conveyor 101 that can move up and down, and the second roller conveyor 202 and the fourth roller conveyor 102, then the first roller conveyor 201 and the third roller conveyor 101 can assume the role of loading and unloading, and the second roller conveyor 202 and the fourth roller conveyor 102 can assume the role of horizontally transporting the hanging box, and the role of the division is to achieve the shortening of the conveyor length of the up and down moving part as much as possible, and reduce the load during the lifting process.

[0022] like Figure 2 and Figure 6 As shown, in this embodiment, in order to make the first roller conveyor 201 and the third roller conveyor 101 have guiding properties during the up and down movement, the bottom of the frame of the first roller conveyor 201 and the third roller conveyor 101 are fixedly installed with sliding rods 5, where at least two sliding rods 5 are symmetrically arranged, and the sliding rods 5 are slidably inserted into the inside of the sleeve rod 6 installed on the ground, and the sleeve rod 6 is internally configured with a sliding groove for sliding, wherein the sliding protrusion 501 configured at the end of the sliding rod 5 is slidably arranged in the sliding groove of the sleeve rod 6, please refer to Figure 6 The movement of the sliding protrusion 501 will be limited by the narrow part of the slide groove, and this is the height required for the first position 3. This design makes the highest lifting position of the first roller conveyor 201 and the third roller conveyor 101 here. The design of this limiting structure can avoid improper rise and collision with the cableway track.

[0023] like Figures 2 to 5As shown, in this embodiment, in order to achieve the up and down movement of the first roller conveyor 201 and the third roller conveyor 101, a cross bar 7 is installed at the bottom of the frames of the first roller conveyor 201 and the third roller conveyor 101. There is also a driving mechanism 8 for driving the first roller conveyor 201 and the third roller conveyor 101 to move to the first position 3 or the second position 4. The driving mechanism 8 includes a base 81 disposed between the first roller conveyor 201 and the third roller conveyor 101. The base 81 is fixedly installed on the ground and a cantilever 82 of equal length on the left and right is rotatably installed thereon. A push rod 83 for pushing the cross bar 7 is fixed at the end of the cantilever 82. At the same time, a round bar 84 is fixed between a pair of sleeve rods 6 located on the ground. A hydraulic rod 85 is rotatably installed on the round bar 84. The other end of the hydraulic rod 85 is rotatably connected to the cantilever 82. Please refer to Figure 3 、 Figure 5 , when the third roller conveyor 101 needs to be lifted to remove the hanging box, the hydraulic rod 85 extends, and the cantilever 82 rotates around the rotation point with the base 81. The push rod 83 pushes the cross bar 7 to drive the third roller conveyor 101 to rise to the first position 3 to pick up the hanging box. It should be emphasized that when the third roller conveyor 101 rises, the cross bar 7 at the bottom of the first roller conveyor 201 relies on the push rod 83 on the cantilever 82 and shows a downward trend in height to form a lever structure among the first roller conveyor 201, the third roller conveyor 101 and the cantilever 82. The advantage of such a design is that during the rising and falling processes of both the first roller conveyor 201 and the third roller conveyor 101, they can both be used as counterweight structures for the lifting and lowering of each other, thereby greatly reducing the output load of the hydraulic rod 85. At the same time, in the case of damage to the hydraulic rod 85, it can prevent the first roller conveyor 201 or the third roller conveyor 101 from hitting the ground rapidly. Specifically, the weights of the first roller conveyor 201 and the third roller conveyor 101 are much greater than the weight of the hanging box and its goods. Even in the case of damage to the hydraulic rod 85, the two can still maintain a balance similar to a "lever" (similar to a traditional steelyard, with a tilt on both left and right but in balance), and will not hit the ground.

[0024] As Figure 3 and Figures 7 to 9 shown, in this embodiment, for details, refer to Figure 3, in order to avoid losses caused by the suspension box falling off the end of the third roller conveyor 101 during the process from the first position 3 to the second position 4; a material blocking mechanism 10 is provided between the connection of the first roller conveyor 201 and the second roller conveyor 202 and between the connection of the third roller conveyor 101 and the fourth roller conveyor 102. The material blocking mechanism 10 is used to prevent the suspension box from detaching from the conveying surface when the first roller conveyor 201 and the third roller conveyor 101 are not in the second position 4, and a baffle 9 is provided at the intersection of the horizontal section and the inclined section of the cableway where the first roller conveyor 201 is located. Setting the baffle 9 can stop the loaded suspension box when it is transferred from the second roller conveyor 202 to the first roller conveyor 201. When the first roller conveyor 201 rises to the first position 3 (as shown in Figure 4 ), the suspension box at the baffle 9 of the first roller conveyor 201 can be hung and moved away by the hook on the cableway.

[0025] Refer in detail to Figure 3 and Figure 8 , and it should be explained that Figure 7 is the state diagram of the material blocking mechanism 10 at the second position 4, Figure 8 is the state diagram of the material blocking mechanism 10 when the third roller conveyor 101 is in the first position 3, Figure 9 is the state diagram when the first roller conveyor 201 is in the first position 3. Specifically, the material blocking mechanism 10 includes a pair of auxiliary rods 1003 whose ends are rotatably connected by a shaft rod 1001 and a pair of baffle rods 1002 whose middle positions are rotatably connected by a shaft rod 1001. The same-direction ends of the two baffle rods 1002 are respectively hinged and installed corresponding to the ends of the pair of auxiliary rods 1003. The shaft rod 1001 on the baffle rod 1002 is fixed to the side of the frame of the second roller conveyor 202 or the third roller conveyor 101, and the shaft rod 1001 on the auxiliary rod 1003 is fixed to the side of the frame of the first roller conveyor 201 or the fourth roller conveyor 102. (Please refer to Figure 3 ). When the third roller conveyor 101 rises to the first position 3, at this time the first roller conveyor 201 descends. Then the upward movement of the third roller conveyor 101 drives the shaft rod 1001 on the baffle rod 1002 to move upward, and the two baffle rods 1002 rotate around the middle shaft rod 1001, and the two auxiliary rods 1003 follow and adapt to rotate, that is: from the state in Figure 7 to the state in Figure 8In the state, after the hanging box is removed from the hook at this time, it reaches the stop bar 1002 under the conveyance of the third roller conveyor 101 and is blocked by the stop bar 1002. Until the third roller conveyor 101 descends to the first position 3, the third roller conveyor 101 is flush with the fourth roller conveyor 102, the stop bar 1002 is retracted, the hanging box is transferred onto the fourth roller conveyor 102, and is conveyed forward to the ground, where on-site staff operate to reload the goods; when the third roller conveyor 101 ascends to the first position 3, the first roller conveyor 201 is in the descending state, and the movement process of the material blocking mechanism 10 is: the descent of the first roller conveyor 201 drives the shaft rod 1001 on the auxiliary rod 1003 to move downward. At this time, the two stop bars 1002 rotate around the shaft rod 1001 in the middle, and the two auxiliary rods 1003 rotate accordingly to adapt, that is Figure 7 The state in Figure 8 changes to the state in Figure 8 At this time, it is also the moment when the hanging box with goods is placed on the second roller conveyor 202. After the hanging box on the third roller conveyor 101 is removed from the hook on the cableway, when the third roller conveyor 101 and the first roller conveyor 201 reach the first position 3, the material blocking mechanism 10 changes from Figure 7 the state in Figure 4 The empty hanging box located on the third roller conveyor 101 is transferred to the fourth roller conveyor 102, and the hanging box carrying goods located on the second roller conveyor 202 moves towards the first roller conveyor 201 to the position of the baffle 9. Then, please refer to

[0026] As Figure 2 shown, in this embodiment, in order to ensure that there is no large left - right conveyance deviation of the hanging box on the conveyance surface to avoid the cableway hook not being able to hook on, guide plates 11 are symmetrically fixed on the side edges of the conveyance surfaces of the first roller conveyor 201, the second roller conveyor 202, the third roller conveyor 101, and the fourth roller conveyor 102. A plurality of guide wheels 12 are equidistantly installed on the guide plates 11, so that the hanging box moves in a straight line on the conveyance surfaces of each conveyor and ensures that it can be hooked by the cableway hook.

[0027] As Figure 1As shown in the figure, in this embodiment, to ensure safety, the first roller conveyor 201, the second roller conveyor 202, the third roller conveyor 101, and the fourth roller conveyor 102 are all installed sunken on the ground at the detour cableway, and the conveying surfaces of the second roller conveyor 202 and the fourth roller conveyor 102 are flush with the ground. A fence 13 is surrounded on the ground outside the first roller conveyor 201, the second roller conveyor 202, the third roller conveyor 101, and the fourth roller conveyor 102. At the same time, a control panel 14 is provided at the fence 13. The control panel 14 is electrically connected to the first roller conveyor 201, the second roller conveyor 202, the third roller conveyor 101, the fourth roller conveyor 102, and the hydraulic pump that controls the movement of the hydraulic rod 85. The control panel 14 here is used to control and adjust the transmission speed of the first roller conveyor 201, the second roller conveyor 202, the third roller conveyor 101, and the fourth roller conveyor 102, and the switch for controlling the telescopic movement of the hydraulic rod 85 is integrated on it.

[0028] The working process of the present invention: First: The on-site operator stands at the control panel 14. By turning on the power, each device operates normally. Since the cableway runs at a slow speed, when the empty hanging box is observed by the naked eye to come down from the blanking end, that is, when it reaches the intersection of the horizontal section and the inclined section of the cableway, the control switch on the control panel 14 is pressed. The control panel 14 controls the hydraulic pump electrically connected to it to work, and then the hydraulic rod 85 extends. It should be noted that there are three switches corresponding to the three states of the extension, shortening, and restoration of the hydraulic rod 85 to the state where the cantilever 82 is in a horizontal state. After the switch is pressed, the hydraulic rod 85 extends and retracts a preset length, and the switches are all integrated on the control panel 14. This is the prior art and will not be explained in detail. During operation, as Figure 2 shown, when the extension switch of the hydraulic rod 85 is pressed, at this time, the hydraulic rod 85 pushes the cantilever 82, and the cantilever 82 rotates around the rotation point with the base 81. The push rod 83 pushes the cross bar 7 to drive the third roller conveyor 101 to rise to the first position 3. Since the third roller conveyor 101 rises and supports the hanging box from the bottom, and because the transmission speed of the third roller conveyor 101 is higher than that of the cableway, it can be detached from the hook on the cableway. As the hanging box is transmitted, it hits the stop bar 1002, restricting the hanging box from continuing to fall forward; When the staff sees that the hanging box is detached from the hook on the cableway, they immediately press the switch to restore the cantilever 82 to the horizontal state. At this time, the third roller conveyor 101 reaches the second position 4, and the hanging box is no longer blocked by the stop bar 1002 and is conveyed outward by the fourth roller conveyor 102; When the staff sees that the empty hanging box reaches the fourth roller conveyor 102 and the hanging box with goods moves from the second roller conveyor 202 to the baffle 9 of the first roller conveyor 201, they press the switch to shorten the hydraulic rod 85. AsFigure 4 , at this time, the first roller conveyor 201 moves upward to the first position 3, and is then hooked by the hook on the cableway. Then the hanging box detaches from the first roller conveyor 201. At this time, the staff presses the switch to restore the cantilever 82 to the horizontal state, realizing a complete material unloading and loading.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
