Description

Technical Field

[0001] This invention relates to the field of cable rack technology, and more specifically to a self-lifting cable rack ground-dragging deployment device and method. Background Technology

[0002] In the coming years, the photovoltaic power station industry will adhere to the development principle of simultaneously promoting centralized and distributed generation, with a focus on distributed photovoltaic power generation. Especially in mountainous environments, the demand for photovoltaic cables is large, and due to the dispersed nature of the sites, cable reels are also placed in a dispersed manner for ease of construction. However, because of the significant weight of the cables, forklifts, loader trucks, and cranes are generally required to lift the cable reels and place them on the laying device. This operation is cumbersome, has a short effective working time, and consumes a lot of time for round trips, yet it is indispensable, causing considerable inconvenience. Therefore, how to reduce or eliminate the reliance on machinery for cable laying is a question worth considering.

[0003] Currently, there are two main types of common cable laying methods. One is the tray-type, where the cable reel is laid on its side and then suspended onto a tray with upper and lower layers, allowing the cable reel to rotate freely on the upper layer. The second is the upright type, where the cable reel is first lifted, a central shaft is inserted into the central hole of the reel, and then a bracket is placed on each side to keep the reel off the ground. Both methods share a common characteristic: they rely heavily on machinery and require mechanical assistance to operate effectively. This makes them relatively cumbersome, and in mountainous environments, the need for mechanical equipment severely limits their use and causes considerable inconvenience.

[0004] In the prior art, such as the utility model patent with patent number 201120456112.X, a rolling cable support frame is disclosed. This structure uses a ramp to roll the cable reel on the frame. However, during operation, rolling is difficult, it is hard to get the cable reel over the ramp, the operation is cumbersome, and the loading and unloading efficiency is low. Based on this, it is necessary to study a self-lifting cable support ground-dragging and deployment device. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a self-lifting cable rack ground-mounted laying device, which effectively solves the problems of difficulty in lifting cable reels and low loading and unloading efficiency in existing cable reel laying devices.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a self-lifting cable rack ground-mounted deployment device, comprising a deployment frame and rollers; the deployment frame includes a guide frame, a support frame, and a stop frame; the support frame has a flat support base at its bottom and an arc-shaped base at its upper part, the arc-shaped base being a partially arc-shaped structure forming the cable rack, and having multiple supports evenly arranged on its circumference; the rollers are rotatably mounted on the supports; the guide frame and the stop frame are respectively disposed at both ends of the support frame; the guide frame includes an upper arc-shaped plate and a lower arc-shaped plate, one end of the upper arc-shaped plate and the lower arc-shaped plate converging to form a flat tip, the other ends being fixed to the upper and lower parts of the support frame respectively, thereby forming an access part at one end of the support frame; the upper arc-shaped plate extends outward toward the arc-shaped base; the stop frame extends inward toward the arc-shaped base and forms a blocking part at the other end of the support frame. It also includes a backstop mechanism mounted on a support frame, comprising a hair presser, a limiting seat, and a backstop block; a storage area is provided at one end of the support frame, the upper end of the backstop block is hinged to the upper part of the storage area, and can be swayed into or out of the storage area, the hair presser is fixed on the backstop block, and the limiting seat is fixed on the support frame, comprising an upper limiting groove, a guide groove, and a limiting groove, the two ends of the guide groove being respectively provided with an upper limiting groove and a lower limiting groove, the hair presser comprising a base, a spring, and a slide rod, the base being provided with a flat hole, the slide rod being slidably fitted into the flat hole and extending outward from the sliding hole, the spring being disposed in the base along the direction of the flat hole and connected to the slide rod, so that the slide rod is held towards the bottom of the flat hole; the outer end of the slide rod is in the limiting seat and can slide within the upper limiting groove, the guide groove, and the limiting groove, the slide rod being in the upper limiting groove, the backstop block being stored in the storage area, and when the slide rod is in the lower limiting groove, the backstop block unfolds outside the storage area and is flush with the bottom of the support frame.

[0007] Beneficial effects: This invention configures a guide frame and a stop frame on a support frame. The support frame supports the cable reel and provides rotatable rollers. To facilitate cable reel insertion, the guide frame has a gradient structure, which provides a guiding surface for the cable reel, thus facilitating cable reel access and reducing the difficulty of lifting the cable reel, making it easier for it to enter the support frame. The stop frame provides a rear-side obstruction during cable reel insertion, preventing the cable reel from detaching from the support frame due to inertia. This invention also incorporates a backstop mechanism, forming a structure on the support frame to release backstop blocks. By releasing these backstop blocks, a backstop structure is created at the connection point between the support frame and the guide frame, preventing the support frame from returning to its original position during cable reel insertion.

[0008] Furthermore, it also includes a torsion spring and a torsion seat. The torsion seat is fixed on the support frame, the middle part of the torsion spring is set on the torsion seat, and the two ends of the torsion spring are respectively arranged on the anti-reverse block and the support frame, so that the anti-reverse block swings in the unfolding direction.

[0009] Beneficial effects: The present invention uses a torsion spring structure to make the anti-reverse block swing outward continuously. After the anti-reverse block disengages from the upper limit groove, it can gradually enter the lower limit groove along the guide groove according to the cable reel connection process. After entering the lower limit groove, the anti-reverse block is in a locked state.

[0010] Furthermore, it also includes a toggle block, which is hinged to the arc-shaped seat and extends into the support space of the arc-shaped seat. The toggle block is provided with a trigger rod, which is slidably fitted in the upper limit groove. When the toggle block is pressed, the trigger rod will push the slide bar out of the upper limit groove.

[0011] Beneficial effects: The present invention can form an automatic release anti-reverse block structure on the support frame without manual operation. Combined with the movement position of the cable reel, the anti-reverse block can be automatically released, thereby forming an anti-reverse structure at the connection position between the support frame and the guide frame, reducing the difficulty of operation and improving the efficiency of operation.

[0012] Furthermore, a roller is rotatably mounted on the actuating block.

[0013] Furthermore, a threaded sleeve is provided at the bottom of the support frame, and an operating rod is threadedly connected inside the threaded sleeve, so that the operating rod can extend outward and form an operating part at the lower part of the blocking part.

[0014] Beneficial effects: By configuring the operating lever, the position of the support frame can be easily adjusted, increasing the number of operating points. At the same time, in the flat position, the operating lever can also serve as an extension of the bottom support, improving the stability of the support.

[0015] Furthermore, a telescopic push rod is provided in the lower limit groove, and the slide rod is pushed out of the lower limit groove by operating the push rod.

[0016] Beneficial effect: By operating the push rod, the slide rod can be disengaged from the lower limit groove and enter the guide groove, thus releasing the locking state of the anti-reverse block.

[0017] Furthermore, the lower part of the support is provided with an adjusting seat, the height of which is adjustable, including an upper adjusting sleeve, a lower adjusting sleeve and an adjusting rod. The upper adjusting sleeve and the lower adjusting sleeve are respectively fixed on the support base and the support. The two ends of the adjusting rod are reverse threads and are adapted to be connected inside the upper adjusting sleeve and the lower adjusting sleeve.

[0018] Beneficial effects: By setting an adjustment seat, the support position of the idler roller can be adjusted to adapt to the outer diameter of the cable reel. When the idler roller wears, it can also be adjusted to ensure full contact with the cable reel and ensure the support effect.

[0019] Furthermore, the support frame is provided with a hanging hole, and a hanging rod is rotatably fitted inside the hanging hole, with a hook at one end of the hanging rod.

[0020] Beneficial effects: By configuring a hanging rod, the present invention can connect the support frame to the hub of the cable reel during the cable reel installation process, thereby facilitating the installation of the cable reel into the support frame.

[0021] A self-lifting cable rack ground-laying method, using the aforementioned self-lifting cable rack ground-laying device, includes the following steps:

[0022] Step 1: Take two deployment devices; insert the guide frame into the space between the cable reel and the ground, so that the guide frame fits snugly against the cable reel;

[0023] Step 2: Adjust the position of the hanging rod and hook it onto the hub of the cable reel;

[0024] Step 3: Roll the cable reel forward so that it passes through the guide frame and enters the support frame;

[0025] Step four: After the cable reel enters the support frame, it sits on the idler roller and can rotate on the idler roller;

[0026] Step 5: After the cable reel is fully deployed, push the cable reel in the opposite direction and remove it from the guide frame.

[0027] Furthermore, as the cable reel passes the guide frame, it presses down against the actuating block. The actuating block pushes downward, causing the sliding rod to disengage from the upper limit groove. The sliding rod then enters the guide groove and the lower limit groove. The anti-reverse block swings out from the storage area and aligns with the bottom of the support base, thus positioning itself. After deployment, the sliding rod is manually or using the operating lever to disengage from the lower limit groove and enter the guide groove. The anti-reverse block enters the storage area, the cable reel is removed from the support frame, and the anti-reverse block finally enters the upper limit groove.

[0028] The beneficial effects of the above technical solution are as follows: This invention provides a device that can lift cable reels without the need for machinery. This not only eliminates reliance on machinery during deployment but also reduces space requirements due to its small size, making it suitable for work sites with limited space and difficult access. Furthermore, the invention features a novel structure, allowing cable reels to be lifted off the ground manually. The device is simple to operate, lightweight, and easy to carry and transport, thus alleviating the pressure on on-site machinery use and providing a convenient cable reel lifting tool.

Detailed Implementation

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0039] Example 1: This example aims to provide a self-lifting cable rack ground-mounted laying device, mainly used to lift cable reels. It is especially suitable for scenarios where the site is small and lifting equipment is inconvenient to enter and exit. In view of the problems of difficulty in lifting cable reels and low loading and unloading efficiency of current cable reel laying devices, this example provides a self-lifting cable rack ground-mounted laying device.

[0040] like Figure 1 As shown, a self-lifting cable rack floor-mounted laying device includes a laying frame and rollers. Structurally, in this embodiment, the laying frame includes a guide frame, a support frame, and a baffle. The support frame serves as the supporting foundation, and its main structure is a steel frame structure, which can provide a stable supporting foundation. In one implementation, the support frame has a keel inside, with a baffle on one side and a hollow rib plate for reinforcement on the other side. The baffle is higher than the support surface of the support frame, thereby forming a blockage and limiting the support frame from the outside.

[0041] The support frame has a flat support base 19 at its bottom, with an anti-slip pad 20 at the bottom of the support base 19. An arc-shaped seat 17 is located on top of the support frame, forming a partially arc-shaped structure that complements the cable tray. Multiple supports 15 are evenly distributed around the circumference of the arc-shaped seat 17. During implementation, the center of the support base 17 is in the middle, with supports evenly distributed on both sides to improve stability. The idler roller 14 is rotatably mounted on the supports 15. The supports 15 serve as the supporting foundation for the idler roller 14. An even number of supports 15 are provided, such as 2, 4, or 6, symmetrically distributed on both sides of the support frame. This allows the cable tray to be supported from both sides of its bottom, ensuring its stability.

[0042] The guide frame and the stop frame are respectively set at both ends of the support frame. The guide frame includes an upper arc plate 1 and a lower arc plate 3. One end of the upper arc plate 1 and the lower arc plate 3 meet to form a flat tip, and the other end is fixed to the upper and lower parts of the support frame respectively, thus forming an access part at one end of the support frame. In implementation, an inner frame 2 is set between the upper arc plate 1 and the lower arc plate 3 to strengthen the overall structural strength.

[0043] During operation, the upper arc-shaped plate 1 extends outward towards the arc-shaped seat and contacts the surface of the cable reel 33, serving as a gradual guide structure to guide the cable reel 33 into the support frame. The lower arc-shaped plate 3 contacts the ground, transitioning with the support seat through its arc-shaped surface (an anti-reverse mechanism is located in the transition fit). As the cable reel 33 rolls, the overall structure gradually flattens and stabilizes.

[0044] The baffle extends inward toward the arc-shaped seat and forms a blocking part at the other end of the support frame. In implementation, the baffle includes a baffle seat 22 and a reinforcing plate 23. The baffle seat 22 is inclined upward, and the reinforcing plate 23 is connected between the end of the support frame and the baffle seat 22. In this embodiment, by configuring a guide frame and a baffle on the support frame, the support frame supports the cable reel 33 and provides it with a rotatable roller 14. To facilitate the entry of the cable reel 33, the guide frame has a gradient structure, which can provide a guiding surface for the cable reel 33, thereby facilitating the access of the cable reel 33, reducing the difficulty of lifting the cable reel 33, and making it easier for it to enter the support frame. The baffle is used to provide a blocking effect from the rear when the cable reel 33 is installed, preventing the cable reel 33 from falling out of the support frame due to inertia.

[0045] The support frame is provided with hanging holes 28, and a hanging rod 21 is rotatably fitted inside the hanging holes 28. One end of the hanging rod 21 is provided with a hook. Multiple hanging holes can be configured to adjust the position of the hanging rod as needed. After the hook is adjusted to a suitable position, it is hung on the cable reel 33 and the hub. In this embodiment, by configuring the hanging rod 21, the support frame can be connected to the hub of the cable reel 33 during the installation of the cable reel 33, thereby facilitating the installation of the cable reel 33 into the support frame.

[0046] A threaded sleeve 25 is provided at the bottom of the support frame, and an operating rod 24 is threadedly connected inside the threaded sleeve 25, allowing the operating rod 24 to extend outward. An operating part is formed at the lower part of the blocking part, and a placement groove 26 is formed inside the support frame to store the operating rod 24. By configuring the operating rod 24, the position of the support frame can be easily adjusted, increasing the number of operating points. At the same time, an operating block is provided on the operating rod. When the operating block is laid flat, it is flush with the bottom of the support base and can also serve as an extension of the bottom support, improving the stability of the support state.

[0047] During operation, after inserting the guide frame obliquely into the cable reel 33, adjust the hook to the appropriate position and hang it on the cable reel 33 and the hub. Then, rotate the operating lever out and pull it out a certain length to act as a lever to press down and make the cable reel roll downwards, thereby positioning the cable reel 33.

[0048] Based on the above-described device, this embodiment also provides a self-lifting cable rack ground-dragging and deployment method, which, using the above-described self-lifting cable rack ground-dragging and deployment device, includes the following steps:

[0049] Step 1: Take two deployment devices; insert the guide frame into the space between the cable reel 33 and the ground, so that the guide frame fits snugly against the cable reel 33;

[0050] Step 2: Adjust the position of the hanging rod and hook it onto the hub of the cable reel 33;

[0051] Step 3: Roll the cable reel 33 forward so that it passes through the guide frame and enters the support frame;

[0052] Step four: After entering the support frame, the cable reel 33 sits on the idler roller 14 and can rotate on the idler roller 14;

[0053] Step 5: After the cable reel 33 is fully deployed, push the cable reel 33 in the reverse direction, and the cable reel 33 will be unloaded through the guide frame.

[0054] This embodiment provides a convenient access and blocking structure for the cable reel 33 by configuring a guide frame and a stop frame on the support frame, reducing the difficulty of lifting the cable reel 33 and improving loading and unloading efficiency. At the same time, the configuration of the hanging rod and the operating rod increases the flexibility and stability of operation, enabling the device to easily cope with scenarios where the site is small and the entry and exit of lifting equipment is inconvenient, greatly increasing the scope of application. The cable reel 33 can be lifted off the ground by manpower alone. The device is simple to operate, lightweight, and easy to carry and transport, which to a certain extent relieves the pressure of on-site machinery use and provides people with a convenient cable reel 33 lifting tool.

[0055] Example 2: In addition to the content of Example 1, this example further provides a backstop mechanism on the support frame. By configuring the backstop mechanism, a structure for releasing the backstop block can be formed on the support frame. By releasing the backstop block, a backstop structure is formed at the connection position between the support frame and the guide frame, preventing the support frame from returning to its original position during the installation of the cable reel 33.

[0056] In specific implementation, this embodiment is as follows: Figure 2-3 As shown, the anti-reverse mechanism is set at the connection between the support frame and the guide frame. The anti-reverse mechanism includes a pressure generator, a limit seat 11, and an anti-reverse block 13. A storage area 27 is provided at one end of the support frame (near the guide frame). The upper end of the anti-reverse block 13 is hinged to the upper part of the storage area 27 and can be placed into or out of the storage area 27. During operation, in the initial stage of use, the anti-reverse block 13 is in the storage area, which facilitates the guide frame and the cable reel 33 to cooperate in guiding the cable reel 33 into the support frame. After it is in place, the anti-reverse block 13 is released to prevent the deployment frame from moving backward.

[0057] In the specific implementation structure, such as Figure 7 As shown, the generator is fixed on the anti-reverse block 13 and cooperates with the limiting seat 11. The limiting seat 11 is fixed on the support frame. The limiting seat 11 includes an upper limiting groove 111, a guide groove 112 and a lower limiting groove 113. The two ends of the guide groove 112 are respectively provided with the upper limiting groove 111 and the lower limiting groove 113. The upper limiting groove 111, the guide groove 112 and the lower limiting groove 113 are three grooves connected. The guide groove 112 is an arc groove. The upper limiting groove 111 and the lower limiting groove 113 are both square grooves. In implementation, the limiting seat 11 is configured as one side or two sides. The generator cooperates with the limiting seat 11 to realize the control of the position of the anti-reverse block 13.

[0058] The hair presser includes a base 8, a spring 7, and a slide rod 4. The base 8 has a flat hole, which, during implementation, corresponds to the upper limit groove 111 and the lower limit groove 113, with the direction of the flat hole matching the upper limit groove 111 and the lower limit groove 113. The slide rod 4 is slidably fitted inside the flat hole and extends outwards. The spring is positioned inside the base 8 along the direction of the flat hole and connected to the slide rod 4, keeping the slide rod 4 at the bottom of the flat hole. The outer end of the slide rod 4 is positioned within a limiting seat 11 and can slide within the upper limit groove 111, the guide groove 112, and the limiting groove. When the slide rod 4 is in the upper limit groove 111, a stop block 13 is stored in a storage area. When the slide rod 4 is in the lower limit groove 113, the stop block 13 extends out of the storage area and is flush with the bottom of the support base 17.

[0059] This embodiment includes a torsion spring 10 and a torsion seat 9, wherein the torsion seat 9 is fixed on the support frame, the middle part of the torsion spring 10 is disposed on the torsion seat 9, and the two ends of the torsion spring 10 are respectively disposed on the anti-reverse block 13 and the support frame, causing the anti-reverse block 13 to swing in the unfolding direction. Through the structure of the torsion spring 10, the anti-reverse block 13 can always swing outward. After the anti-reverse block 13 disengages from the upper limit groove 111, it can gradually enter the lower limit groove 113 along the guide groove 112 according to the cable reel 33 connection process. After entering the lower limit groove 113, the anti-reverse block 13 is in a locked state.

[0060] In order to achieve automatic triggering of the slide bar 4, this embodiment is equipped with a toggle block 5. The toggle block 5 is hinged on the arc-shaped seat and extends into the support space of the arc-shaped seat. A trigger rod is provided on the toggle block 5. The trigger rod is slidably fitted in the upper limit groove 111. When the toggle block 5 is pressed, the trigger rod will push the slide bar 4 out of the upper limit groove 111.

[0061] During implementation, a bracket is provided on the rear side of the actuating block 5, and the end of the bracket is hinged to the arc-shaped seat. A roller is provided on the actuating block 5, which can contact the cable reel to avoid friction. During implementation, the actuating block spans the arc-shaped seat, and when the cable reel is connected, it presses down on the actuating block from the top, causing the trigger rod to press the slide rod inward and push the slide rod out of the upper limit groove. Thus, the anti-reverse block can be released without manual operation. When the slide rod returns to its original position, the actuating block can be reset by the action of the spring.

[0062] In addition, in this embodiment, a limiting hole can be opened in the lower limiting groove, and a positioning hole is provided on the slide rod. In the extreme state, the positioning hole can correspond to the limiting hole, and by applying a positioning pin in the limiting hole and the positioning hole, the state can be locked, thus ensuring the working stability of the anti-reverse block.

[0063] This embodiment features an automatically releasing anti-reverse block 13 structure on the support frame, eliminating the need for manual operation. Combined with the movement position of the cable reel 33, the anti-reverse block 13 can be automatically released, thus forming an anti-reverse structure at the connection point between the support frame and the guide frame. This reduces operational difficulty and improves operational efficiency. When passing the guide frame, the cable reel 33 presses down against the actuating block 5. The actuating block 5 presses downwards, causing the sliding rod 4 to disengage from the upper limit groove 111. The sliding rod 4 enters the guide groove 112 and then the lower limit groove 113. The anti-reverse block 13 swings out from the storage area and becomes flush with the bottom of the support base 17, thus positioning itself. After deployment, the sliding rod 4 is manually or using an operating lever to disengage from the lower limit groove 113 and enter the guide groove 112. The anti-reverse block 13 enters the storage area, the cable reel 33 is removed from the support frame, and the anti-reverse block 13 finally enters the upper limit groove 111.

[0064] When using this embodiment, as follows: Figure 4 , 5As shown in Figure 8, two sets of deployment racks need to be used simultaneously. Before use, check the equipment for damage and obvious deformation, and ensure the anti-reverse mechanism is in the retracted state. The operating lever should be in the threaded connection state. After inspection, hold the operating lever with one hand and support the bottom with the other to insert the front end of the tapered guide frame into the gap between the hub of cable reel 33 and the ground. Then, adjust the hook and hang it on the hub. After the above operation is completed, remove the operating lever and pull it out 2 / 3 of its length. Then, two people pull it down diagonally backward at the same time. If the cable reel 33 is too heavy, a steel pipe or pry bar can be used to lengthen the operating lever to achieve the purpose of rotation. When the cable reel 33 rolls forward, it will first pass the anti-reverse mechanism. When it passes the actuating lever and triggers the pressure trigger, the anti-reverse block 13 is released. As the cable reel 33 is in place, the entire device is leveled and the anti-reverse block 13 is also in place at the same time to prevent the cable reel 33 from falling back due to inertia. Do not fully pull out the operating lever during the positioning process. In this way, the operating lever also plays a role in preventing tipping. After the above operations are completed, cable laying can begin. Once the cable is laid, first pull the slide bar 4 out of the lower limiting groove and into the guide groove 112. Then grasp the operating rod and lift it upwards. During the lifting process, the anti-reverse block 13 is squeezed and reset, and the cable reel 33 is pushed out. This completes the entire cable laying process. Alternatively, if the cable reel 33 cannot be rotated manually, the device can be positioned, and multiple people can use ropes to rotate the cable reel 33 to position it. This embodiment greatly reduces the excessive reliance on construction machinery during cable laying, and its simple operation effectively adapts to the complex and varied geographical environment of mountainous terrain.

[0065] Example 3: This example provides a tooling for releasing the slide bar 4 from the lower limit groove 113.

[0066] like Figure 7 As shown, after the display rack is used up, the anti-reverse block 13 needs to be stored in the storage area. In order to release the locking state, this embodiment is equipped with a telescopic push rod 29 in the lower limit groove 113. By operating the push rod, the slide rod 4 is pushed out from the lower limit groove 113.

[0067] In this embodiment, the push rod structure can be installed on it by rotating it with a thread. As the thread advances, the push rod can be operated to disengage the slide rod 4 from the lower limit groove 113 and enter the guide groove 112, thereby releasing the locking state of the anti-reverse block 13.

[0068] Example 4 is adaptable to different sizes of cable reels 33, or according to the wear condition of the idler roller 14, this example can make the idler roller 14 and the cable reel 33 fit tightly by adjusting the height of the seat.

[0069] In this embodiment, as shown Figure 8As shown, an adjusting seat is provided at the lower part of the support 15. The height of the adjusting seat is adjustable and includes an upper adjusting sleeve 30, a lower adjusting sleeve 31, and an adjusting rod 32. The upper adjusting sleeve 30 and the lower adjusting sleeve 31 are respectively fixed on the support base 17 and the support 15. The two ends of the adjusting rod 32 are reverse-threaded and are adapted to be connected inside the upper adjusting sleeve and the lower adjusting sleeve 31. In this embodiment, by providing an adjusting seat, the support position of the idler roller 14 can be adjusted to adapt to the outer diameter of the cable reel 33. When the idler roller 14 wears, it can also be adjusted to ensure that it can fully contact the cable reel 33 and ensure the support effect.

[0070] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is to provide a device that can lift cable reels without the need for machinery, which not only eliminates the dependence on machinery during deployment, but also has a small size and occupies little space, making it suitable for work sites with limited space and difficult access. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
