Description

Technical Field

[0001] The invention relates to the technical field of cable racks, and in particular to a self-lifting cable rack dragging and spreading device and a method thereof. Background Art

[0002] In the next few years, the photovoltaic power station industry will adhere to the development principle of centralized and distributed development, with a focus on distributed photovoltaic power generation. Especially in mountainous environments, the amount of photovoltaic cables used is large, and because the site is relatively scattered, in order to facilitate construction, the placement of cable drums is also scattered. However, due to the heavy weight of the cable, when laying the cable, it is generally necessary to use auxiliary tools such as forklifts, shovels and cranes to lift the cable drum and place it on the laying device. The operation is more troublesome, the effective working time is short, and the round trip takes a long time, but it is indispensable and has brought great trouble to people. So how to reduce or get rid of the dependence of laying cables on machinery is a question worth thinking about.

[0003] There are two main types of common cable deployment at present. One is the tray type, where the cable reel is laid on its side and then hung on the tray. The tray is divided into two layers, the upper and lower layers, and the cable reel can rotate freely on the upper layer. The second is the upright type, where the cable reel is first lifted and the central axis is inserted into the central circular hole of the cable reel, and then a bracket is placed on each side to lift the cable reel off the ground. Both methods have a common feature, that is, they cannot be separated from machinery, and both require mechanical assistance to work effectively. The operation is relatively troublesome. For mountainous environments, the above devices all need the help of mechanical equipment, which has great limitations in use and brings troubles to people.

[0004] In the prior art, for example, the utility model patent No. 201120456112.X discloses a rolling cable rack, which uses a slope to roll the cable drum on the rack body. However, during operation, rolling is difficult, and it is difficult to move the cable drum over the slope, which is troublesome to operate and has low loading and unloading efficiency. Based on this, it is necessary to study a self-lifting cable rack ground dragging and unfolding device. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a self-lifting cable rack ground-drag deployment device, which effectively solves the problems of difficult cable reel lifting and low loading and unloading efficiency in existing cable reel deployment devices.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a self-lifting cable rack ground dragging and unfolding device, including an unfolding frame and a roller; the unfolding frame includes a guide frame, a support frame and a blocking frame, the bottom of the support frame has a flat support seat, the upper part of which is provided with an arc seat, the arc seat is a partial arc structure, formed with the cable rack, and a plurality of supports are evenly arranged on its circumference, and the roller is rotatably arranged on the support; the guide frame and the blocking frame are respectively arranged at two ends of the support frame, the guide frame includes an upper arc plate and a lower arc plate, one end of the upper arc plate and the lower arc plate intersect and form a flat tip, and the other end is respectively fixed to the upper and lower parts of the support frame, thereby forming an access part at one end of the support frame, and the upper arc plate extends to the outside of the arc seat; the blocking frame extends to the inside of the arc seat and forms a blocking part at the other end of the support frame. The cam is secured to the upper edge of the support frame, and the cam is secured on a 40-degree angle to the upper edge of the support frame, the cam being secured to the upper edge of the support frame when the cam is in a state of being moved in an unsteady motion.

In order to facilitate the cable reel to enter therein, the guide frame has a gradual structure, which can provide a guide surface for the cable reel, thereby facilitating the access of the cable reel, reducing the difficulty of lifting the cable reel, and making it easier to enter the support frame. The stop frame is used to provide obstruction from the rear side when the cable reel is loaded, so as to prevent the cable reel from falling out of the support frame due to inertia. The present invention can form a structure for releasing the stop block on the support frame through the stop mechanism, and by releasing the stop block, a stop structure is formed at the connection position between the support frame and the guide frame, so as to prevent the support frame from returning to its position during the loading process of the cable reel.

[0008] Furthermore, it also includes a torsion spring and a torsion seat, wherein the torsion seat is fixed on the support frame, the middle part of the torsion spring is arranged on the torsion seat, and the two ends of the torsion spring are respectively arranged on the stop block and the support frame, and the stop block is swung in the expansion direction.

[0009] Beneficial effect: The present invention uses a torsion spring structure to enable the stop block to always swing outward. After the stop block is separated from the upper limit groove, it can gradually enter the lower limit groove along the guide groove according to the access process of the cable drum. After entering the lower limit groove, the stop block is in a locked state.

[0010] Furthermore, it also includes a toggle block, which is hinged on the arc seat and extends to the supporting space of the arc seat. A trigger rod is provided on the toggle block, and the trigger rod is slidably mounted in the upper limit groove. When the toggle block is pressed, the trigger rod will push the sliding rod out of the upper limit groove.

Combined with the movement position of the cable drum, the backstop block can be automatically released, thereby forming a backstop structure at the connection position between the support frame and the guide frame, reducing the difficulty of operation and improving the operating efficiency.

[0012] Furthermore, a roller is rotatably arranged on the toggle block.

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

[0014] Beneficial effect: By configuring the operating rod, the position of the support frame can be easily adjusted, and the operating points are increased. At the same time, in the flat state, the operating rod can also serve as an extension of the bottom support, thereby improving the stability of the support state.

[0015] Furthermore, a retractable ejector rod is disposed in the lower limit groove, and the slide bar is ejected from the lower limit groove by operating the ejector rod.

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

[0017] Furthermore, an adjustment seat is provided at the lower part of the support, and the height of the adjustment seat is adjustable, including an upper adjustment sleeve, a lower adjustment sleeve and an adjustment rod. The upper adjustment sleeve and the lower adjustment sleeve are respectively fixed on the support seat and the support, and the two ends of the adjustment rod are reverse-threaded and adapted to be connected in the upper adjustment sleeve and the lower adjustment sleeve.

When the roller is worn, it can also be adjusted so that it can fully contact with the cable drum to ensure the supporting effect.

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

[0020] Beneficial effect: The present invention is configured with a hanging rod, so that during the installation of the cable drum, the support frame can be connected to the hub of the cable drum, thereby facilitating the installation of the cable drum into the support frame.

[0021] A method for laying out a self-lifting cable rack by dragging and spreading it on the ground, using the self-lifting cable rack by dragging and spreading it on the ground, comprises the following steps: Step 1: Take two deployment devices; insert the guide frame into the space between the cable drum and the ground, so that the guide frame fits the cable drum; Step 2: Adjust the position of the hanging rod and hook it on the hub of the cable drum; Step 3, rolling the cable drum forward so that the cable drum enters the support frame through the guide frame; Step 4: After entering the support frame, the cable drum is seated on the rollers and can rotate on the rollers; Step 5: After the cable reel is unfolded, push the cable reel in the reverse direction and remove it through the guide frame.

[0022] Furthermore, when passing through the guide frame, the cable reel will press down on the toggle block, and the toggle block will squeeze downward to disengage the slide bar from the upper limit slot, and the slide bar will enter the guide slot and the lower limit slot, and the stop block will swing out from the storage area and be flush with the bottom of the support seat, and the stop block will be in place; after the deployment is completed, the slide bar will be disengaged from the lower limit slot manually or by using an operating lever, and enter the guide slot, the stop block will enter the storage area, the cable reel will be removed from the support frame, and the stop block will finally enter the upper limit slot.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a self-lifting cable rack ground-drag deployment device, which is mainly used for lifting cable reels, and is particularly suitable for scenarios where the site is small and the lifting equipment is inconvenient to enter and exit. In view of the problem that the current cable reel deployment device has difficulties in lifting the cable reel and low loading and unloading efficiency, this embodiment provides a self-lifting cable rack ground-drag deployment device.

[0027] like Figure 1 As shown in the figure, a self-lifting cable rack ground-drag deployment device includes a deployment frame and rollers; in terms of structure, the deployment frame of this embodiment includes a guide frame, a support frame and a baffle frame, wherein the support frame serves as a supporting base, and its main structure is a steel frame structure, which can provide a stable supporting base. As an implementation method, there is a keel inside the support frame, a baffle is arranged on one side of the support frame, and the other side is reinforced with a hollow rib plate, and the baffle is higher than the supporting surface of the support frame, thereby forming a blockage, and the support frame can be limited from the outside.

[0028] The bottom of the support frame has a flat support seat 19, and an anti-skid pad 20 is arranged at the bottom of the support seat 19. The upper part thereof is provided with an arc seat 17, wherein the arc seat 17 is a partial arc structure, forming a cable rack, and multiple supports 15 are evenly arranged on its circumference. During implementation, the center of the support seat 17 is in the middle, and both sides are evenly arranged, which can improve its stability. The roller 14 is rotatably arranged on the support 15; the support 15 serves as the supporting base of the roller 14, and the support 15 is configured as an even number, such as 2, 4 or 6, and the support 15 is symmetrically distributed on both sides of the support frame, so that the cable drum can be supported from both sides of the bottom of the cable drum to ensure its support stability.

[0029] The guide frame and the baffle frame are respectively arranged at the two ends of the support frame, wherein 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 intersect and form a flat tip, and the other ends are respectively fixed to the upper and lower parts of the support frame, thereby forming an access part at one end of the support frame. During implementation, an inner frame 2 is arranged between the upper arc plate 1 and the lower arc plate 3, and the overall structural strength is strengthened by the inner frame 2.

[0030] When working, the upper arc plate 1 extends to the outside of the arc seat and contacts the surface of the cable drum 33, serving as a gradual guide structure to guide the cable drum 33 into the support frame. The lower arc plate 3 contacts the ground, and transitionally cooperates with the support seat through the arc surface (the stop mechanism is provided in the transitional cooperation part), and as the cable drum 33 is rolled, the whole structure is gradually laid flat and in a stable state. The retaining frame extends to the inner side of the arc seat and forms a blocking portion at the other end of the support frame. When implemented, the retaining frame includes a retaining seat 22 and a reinforcing plate 23. The retaining seat 22 is tilted upward, and the reinforcing plate 23 is connected between the support frame and the end of the retaining seat 22. In this embodiment, a guide frame and a retaining frame are arranged on the support frame, and the support frame is used to support the cable drum 33, and a rotatable roller 14 is provided for it. In order to facilitate the cable drum 33 to enter therein, the guide frame has a gradual structure, which can provide a guide surface for the cable drum 33, thereby facilitating the access of the cable drum 33, reducing the difficulty of lifting the cable drum 33, and making it easier to enter the support frame. The retaining frame is used to provide a block from the rear side when the cable drum 33 is loaded, so as to prevent the cable drum 33 from falling out of the support frame due to inertia.

[0031] The support frame is provided with a hanging hole 28, in which a hanging rod 21 is rotatably mounted, and a hook is provided at one end of the hanging rod 21. The hanging hole 28 can be configured to be multiple, so that the position of the hanging rod can be adjusted according to the situation, and the hook can be hung on the cable drum 33 and the hub after being adjusted to a suitable position. In this embodiment, by configuring the hanging rod 21, the support frame can be connected to the hub of the cable drum 33 during the installation of the cable drum 33, so that the cable drum 33 can be easily installed into the support frame.

[0032] The bottom of the support frame is provided with a screw sleeve 25, and an operating rod 24 is connected to the screw sleeve 25 through a thread, so that the operating rod 24 can extend outward, and an operating portion is formed at the lower part of the blocking portion, and a placement groove 26 is formed inside the support frame, which can accommodate the operating rod 24. By configuring the operating rod 24, the position of the support frame can be easily adjusted, and the operating points are increased. At the same time, an operating block is provided on the operating rod, and the operating block is flush with the bottom of the support seat in a flat state, and can also be used as an extension of the bottom support, thereby improving the stability of the support state.

[0033] During operation, after the guide frame is obliquely inserted into the cable drum 33, the hook is adjusted to a suitable position and hung on the cable drum 33 and the wheel hub. Then the operating rod is rotated out, and a length is pulled out as a lever to press down to make the downward pressing side of the cable drum roll, so that the cable drum 33 is in place.

[0034] Based on the above device, this embodiment also provides a method for dragging and deploying a self-lifting cable rack, which uses the above self-lifting cable rack dragging and deploying device, including the following steps: Step 1: Take two deployment devices; insert the guide frame into the space between the cable drum 33 and the ground, so that the guide frame fits the cable drum 33; Step 2: adjust the position of the hanging rod and hang it on the hub of the cable drum 33; Step 3, rolling the cable drum 33 forward so that the cable drum 33 enters the support frame through the guide frame; Step 4: After entering the support frame, the cable drum 33 is seated on the roller 14 and can rotate on the roller 14; Step 5: After the cable drum 33 is unfolded, the cable drum 33 is pushed in the reverse direction and the cable drum 33 is removed through the guide frame.

[0035] This embodiment provides a convenient access and blocking structure for the cable drum 33 by configuring a guide frame and a blocking frame on the support frame, reducing the difficulty of lifting the cable drum 33 and improving the loading and unloading efficiency. At the same time, the configuration of the hanging rod and the operating rod increases the flexibility and stability of the operation, so that the device can easily cope with the scene of small site and inconvenient access of the lifting equipment, greatly increasing the scope of application, and the cable drum 33 can be lifted off the ground by manpower alone. The device is simple to operate, light in weight, and convenient to carry and transport, which relieves the pressure of on-site mechanical use to a certain extent and provides people with a cable drum 33 lifting tool that is easy to operate.

[0036] Embodiment 2: In view of the contents in Embodiment 1, this embodiment 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, thereby preventing the support frame from returning to its original position during the installation of the cable drum 33.

[0037] In the specific implementation of this embodiment, Figure 2-3 As shown in the figure, the anti-recoil mechanism is arranged at the connection between the support frame and the guide frame, and the anti-recoil mechanism includes a presser, a limit seat 11 and an anti-recoil block 13; a storage area 27 is arranged at one end of the support frame (close to the guide frame), and the upper end of the anti-recoil block 13 is hinged to the upper part of the storage area 27, and can be swung into or out of the storage area 27. During operation, at the initial stage of use, the anti-recoil block 13 is in the storage area, so that the guide frame and the cable drum 33 cooperate to guide the cable drum 33 onto the support frame. After it is in place, the anti-recoil block 13 is released to prevent the display frame from retreating.

[0038] In the specific implementation structure, Figure 7 As shown in the figure, the trigger is fixed on the stop block 13 and cooperates with the limit seat 11. The limit seat 11 is fixed on the support frame. The limit seat 11 includes an upper limit groove 111, a guide groove 112 and a lower limit groove 113. The upper limit groove 111 and the lower limit groove 113 are respectively arranged at both ends of the guide groove 112, and the upper limit groove 111, the guide groove 112 and the lower limit groove 113 are connected as three grooves. The guide groove 112 is an arc groove, and the upper limit groove 111 and the lower limit groove 113 are both square grooves. During implementation, the limit seat 11 is configured as one side or two sides, and the trigger cooperates with the limit seat 11 to realize the control of the position of the stop block 13.

[0039] The hair press comprises a seat body 8, a spring 7 and a slide bar 4. A flat hole is arranged in the seat body 8. When implemented, the flat hole corresponds to the upper limit groove 111 and the lower limit groove 113, and the direction of the flat hole matches the upper limit groove 111 and the lower limit groove 113. The slide bar 4 is slidably sleeved in the flat hole and extends outward from the slide hole. The spring is arranged in the seat body 8 along the direction of the flat hole and connected to the slide bar 4 to keep the slide bar 4 toward the bottom of the flat hole. The outer end of the slide bar 4 is in the limit seat 11 and can slide in the upper limit groove 111, the guide groove 112 and the limit groove. The slide bar 4 is in the upper limit groove 111, and the stop block 13 is stored in the storage area. When the slide bar 4 is in the lower limit groove 113, the stop block 13 is unfolded outside the storage area and is flush with the bottom of the support seat 17.

[0040] 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 arranged on the torsion seat 9, and the two ends of the torsion spring 10 are respectively arranged on the stop block 13 and the support frame, and the stop block 13 is swung in the deployment direction. Through the structure of the torsion spring 10, the stop block 13 can always swing outward, and after the stop block 13 is separated from the upper limit groove 111, it can gradually enter the lower limit groove 113 along the guide groove 112 according to the access process of the cable drum 33. After entering the lower limit groove 113, the state of the stop block 13 is in a locked state.

[0041] In order to realize automatic triggering of the slide bar 4, the present embodiment is provided with a toggle block 5, which is hinged on the arc seat and extends to the supporting space of the arc seat. A trigger rod is provided on the toggle block 5, and the trigger rod is slidably mounted 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.

[0042] During implementation, a bracket is provided on the rear side of the toggle block 5, and the end of the bracket is hinged on the arc seat. A roller is provided on the toggle block 5, and the roller can contact the cable drum to avoid friction. During implementation, the toggle block spans the arc seat, and when the cable drum is connected, the toggle block is pressed downward from the top, so that the trigger rod squeezes the slide bar inward, pressing the slide bar out of the upper limit groove, so that the stop block can be released without manual operation. When the slide bar is reset, the toggle block can be reset by the action of the spring.

[0043] In addition, when this embodiment is implemented, a limit hole can be opened in the lower limit groove, and a positioning hole is provided on the slide rod. Under the extreme state, the positioning hole can correspond to the limit hole, and by applying a positioning pin in the limit hole and the positioning hole, the state can be locked, thereby ensuring the working stability of the stop block.

[0044] In this embodiment, a structure for automatically releasing the stop block 13 is formed on the support frame, and manual operation is not required. Combined with the moving position of the cable drum 33, the stop block 13 can be automatically released, thereby forming a stop structure at the connection position between the support frame and the guide frame, reducing the difficulty of operation and improving the operation efficiency. When passing through the guide frame, the cable drum 33 will press the toggle block 5 downward, and the toggle block 5 will squeeze downward to disengage the slide bar 4 from the upper limit groove 111, and the slide bar 4 will enter the guide groove 112 and the lower limit groove 113. The stop block 13 is swung out of the storage area and flush with the bottom of the support seat 17, and the stop block 13 is in place; after the unfolding is completed, the slide bar 4 is disengaged from the lower limit groove 113 manually or by using an operating rod, and enters the guide groove 112, the stop block 13 enters the storage area, the cable drum 33 is removed from the support frame, and the stop block 13 finally enters the upper limit groove 111.

[0045] This embodiment is used as Figure 4 , 5As shown in 8, two sets of display rack devices need to be used at the same time. Before use, check whether the device is damaged or obviously deformed, and the anti-retraction mechanism is in a retracted state. The operating rod is in a threaded connection state. After the inspection is completed, hold the operating rod with one hand and support the bottom with the other hand to insert the front end of the gradient guide frame into the gap between the cable drum 33 hub and the ground, and then hang the hook on the hub after adjusting it. After the above operations are completed, the operating rod is unloaded and pulled out 2 / 3 of the length of the operating rod. After that, two people pull it down obliquely to the rear at the same time. If the cable drum 33 is too heavy, a steel pipe or a crowbar can be used to lengthen the operating rod to achieve the purpose of rotation. When the cable drum 33 rolls forward, it will first pass through the anti-retraction mechanism. When it presses the toggle rod and triggers the trigger, the anti-retraction block 13 is released. As the cable drum 33 is in place, the entire device is flat and in place, and the anti-retraction block 13 is also in place at the same time to prevent the cable drum 33 from falling back due to inertia. The operating rod should not be completely pulled out during the placement process. In this way, the operating rod also plays an anti-overturning role. After the above operations are completed, the cable can be deployed. After the cable is deployed, first pull the slide bar 4 out of the lower limit groove to the guide groove 112. Then grab the operating rod. Lift upward, and during the lifting process, the stop block 13 is squeezed and reset, and the cable drum 33 is pushed out. At this point, a whole set of cable deployment actions is completed. In addition, if there is insufficient manpower to rotate the cable drum 33, then after the device is in place, use ropes and multiple people to rotate the cable drum 33 to put it in place. This embodiment can greatly reduce the excessive reliance on construction machinery when deploying cables, and is simple to operate, and can effectively adapt to the complex and changeable geographical environment of the mountains.

[0046] Embodiment 3: This embodiment provides a tool for releasing the slide bar 4 from the lower limit groove 113 .

[0047] like Figure 7 As shown in the figure, after the display rack is used, the stop block 13 needs to be stored in the storage area. In order to release the locked state, a retractable push rod 29 is configured in the lower limit groove 113 in this embodiment, and the slide bar 4 is pushed out from the lower limit groove 113 by operating the push rod.

[0048] The push rod structure of this embodiment can be set thereon by rotating the thread, and as the thread advances, the push rod can be operated to make the slide bar 4 disengage from the lower limit groove 113 and enter the guide groove 112, thereby releasing the locking state of the stop block 13.

[0049] Embodiment 4 has a certain degree of adaptability to cable drums 33 of different sizes, or according to the wear of the roller 14, this embodiment can make the roller 14 and the cable drum 33 fit closely by adjusting the height of the seat.

[0050] In this embodiment, Figure 8As shown in , an adjustment seat is provided at the lower part of the support 15, and the height of the adjustment seat is adjustable, including an upper adjustment sleeve 30, a lower adjustment sleeve 31 and an adjustment rod 32. The upper adjustment sleeve 30 and the lower adjustment sleeve 31 are fixed on the support seat 17 and the support 15 respectively, and the two ends of the adjustment rod 32 are reverse threads and are adapted to be connected in the upper adjustment sleeve and the lower adjustment sleeve 31. By providing the adjustment seat, this embodiment can adjust the support position of the roller 14, so as to adapt to the outer diameter of the cable drum 33. When the roller 14 is worn, it can also be adjusted so that it can fully contact with the cable drum 33 to ensure the support effect.

[0051] The above-mentioned embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to provide a device that can lift the cable drum without the aid of machinery, which not only gets rid of the dependence on machinery when deploying, but also has a small size and occupies less space, and is suitable for small sites and difficult to enter and exit work sites.
