Description

Technical Field

[0001] This invention relates to the field of lifting device technology, specifically a remote-controlled pipeline lifting device. Background Technology

[0002] Modern architecture requires that the layout of mechanical and electrical pipelines not only consider functionality but also aesthetics and space utilization. Lifting devices can precisely install mechanical and electrical pipeline modules in designated locations, optimizing pipeline layout and saving space.

[0003] Conventional lifting devices simply insert two fork arms into the bottom of the pipeline module to be lifted, and then lift it. During this process, there are no protective components around the pipeline module, and because the top surface of the fork arms used to place the pipeline module is relatively smooth, the pipeline module may shift or shake during the lifting process after it is placed, resulting in instability of the pipeline module and increasing the risk of damage. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a remote-controlled pipeline lifting device to solve the problem of low stability of pipeline modules during lifting mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote-controlled pipeline lifting device, comprising a mobile frame, on which a hydraulic lifting assembly is slidably mounted, and on which a rack assembly is mounted; The rack assembly consists of a back panel and two forks on the front of the back panel. A limiting component is installed between the two forks. When the pipeline module moves onto the two forks, the limiting component and the back panel clamp and lock the pipeline module from the front and back. The limiting component includes a support structure disposed between two fork arms. The support structure is provided with a positioning shaft, and a baffle is sleeved on the outer surface of the positioning shaft. Several compound torsion springs are sleeved on the outer surface of the positioning shaft to adjust the baffle to be inclined upward from front to back. A through groove is provided on the support structure, and a telescopic structure rotatably connected to the rear side of the baffle is provided in the through groove. When the front side of the pipeline module placed on the fork arm is in contact with the rear side of the telescopic structure and the telescopic structure is vertically distributed, the front side of the telescopic structure is in contact with the inner front wall of the through groove.

[0006] Preferably, the swing angle of the baffle is between 0° and 30°. When the baffle is arranged in a horizontal state, its top surface is at the same height as the top surface of the fork arm, and the rear side of the telescopic structure is in contact with the inner rear wall of the through groove.

[0007] Preferably, the supporting structure includes a supporting base plate, with side plates fixed on both sides of the supporting base plate, a positioning shaft installed between the two side plates, and a docking platform with the same number of duplex torsion springs installed at the bottom of the supporting base plate.

[0008] Preferably, the compound torsion spring consists of two spring coils, a U-shaped metal strip connecting the two spring coils on opposite sides, and an L-shaped metal strip connecting the two spring coils on opposite sides, with the top of the L-shaped metal strip fitting against the bottom surface of the baffle.

[0009] Preferably, the U-shaped metal strip is fitted onto the docking platform, and the top surface of the docking platform is in contact with the bottom surface of the baffle when it is arranged in a horizontal state.

[0010] Preferably, the rear side of the baffle is provided with a groove, and a connecting shaft is installed between the inner walls of the two sides of the groove.

[0011] Preferably, the telescopic structure includes a channel plate inserted into the through slot, two base brackets installed at the bottom of the supporting base plate, and the front and rear inner widths of the base brackets are the same as the width of the through slot. Both sides of the channel plate are rotatably connected to sliding columns inserted into the base brackets. An extension plate is slidably connected inside the channel plate. The extension plate and the back of the channel plate are on the same vertical plane, and the vertical plane is located behind the baffle.

[0012] Preferably, each of the two fork arms has a slot and an inner groove on its opposite side. A threaded screw is rotatably connected inside the slot, and a dial connected to the threaded screw is provided in the inner groove. A slider connected to the supporting structure is sleeved on the threaded screw.

[0013] By employing the above technical solution, the present invention provides a remote-controlled pipeline lifting device, which has at least the following beneficial effects: 1. This invention, through the overall composition of a support structure, positioning shaft, baffle and compound torsion spring, combined with the backrest plate at the rear end of the fork arm, can form an automatic adjustment and clamping mechanism. After the pipeline module is placed on the fork arm, it forms a front and rear clamping limit, which can effectively prevent the pipeline module from slipping or changing position during the lifting process, enhance the stability of the pipeline module, and reduce the risk of damage to the pipeline module during transportation.

[0014] 2. By using a docking platform, this invention can ensure that the height and horizontal position of the U-shaped metal strip remain unchanged, thus avoiding affecting the storage of external force by the compound torsion spring. In addition, it can provide sufficient support for the horizontally arranged baffle and prevent it from tilting downward continuously, which would exceed the force range of the compound torsion spring. This effectively ensures the service life and performance of the compound torsion spring.

[0015] 3. When the baffle is adjusted to be tilted upward from front to back, the thickness of the extension plate that exceeds the rear side of the baffle will fill the gap between the rear side of the baffle and the pipeline module, thus effectively improving the clamping and limiting effect on the pipeline module.

[0016] 4. The present invention can adjust the front and rear position of the limiting component between the two forks according to the width of the pipeline module, so that it can cooperate with the backrest to clamp and limit the pipeline module for various specifications of pipeline modules.

[0019] 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 some embodiments of the present invention, and not all embodiments. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] Example 1 Please see Figures 1-7 This embodiment proposes a remote-controlled pipeline lifting device that can clamp and limit the placed pipeline modules from the front and back to prevent them from falling. Its basic structure consists of a movable frame 1, a hydraulic lifting assembly 2 slidably mounted on the movable frame 1, and a shelf assembly 3 mounted on the hydraulic lifting assembly 2. In this embodiment, the specific composition of the hydraulic lifting assembly 2 can be of various forms known to those skilled in the art. In one embodiment of the invention, the hydraulic lifting assembly 2 mainly consists of a guide frame slidably connected to the inside of the movable frame 1, a hydraulic cylinder installed at the bottom of the movable frame 1, a roller frame at the top of the hydraulic lifting structure, and a chain installed on the rear wall of the movable frame 1 and connecting to the shelf assembly 3 around the roller frame, etc., and the shelf assembly 3 is slidably connected to the guide frame through an embedded block. The entire hydraulic lifting assembly 2 aims to use the hydraulic cylinder to drive the roller frame to move up and down, and in conjunction with the chain and guide frame, adjust the height of the shelf assembly 3. Its operating principle and function are consistent with existing technologies, and therefore will not be described in detail here. In addition, the hydraulic lifting assembly 2 includes a wireless signal receiving module and an electronic control button, which is designed to enable both press control and wireless remote control, ensuring safety while improving ease of use.

[0021] Under normal circumstances, the area on shelf assembly 3 used for placing goods is relatively smooth. However, during the lifting process after the pipeline module is placed, the module may shift or shake, causing instability and increasing the risk of damage. To effectively solve this problem, such as... Figure 1 , Figures 3-6 As shown, the rack assembly 3 consists of a back panel 301 and two forks 302 set on the front of the back panel 301. A limiting component 4 is installed between the two forks 302. When the pipeline module moves onto the two forks 302, the limiting component 4 and the back panel 301 clamp and lock the pipeline module from the front and back, which can effectively prevent the pipeline module from moving back and forth significantly during the lifting process and ensure the stability of the pipeline module.

[0022] Specifically, the limiting component 4 includes a support structure 401 disposed between the two fork arms 302. The support structure 401 has a positioning shaft 402, and a baffle 403 is fitted onto the outer surface of the positioning shaft 402. Several compound torsion springs 404 are fitted onto the outer surface of the positioning shaft 402. A through groove 405 is formed on the support structure 401, and a telescopic structure 406 rotatably connected to the rear side of the baffle 403 is disposed within the through groove 405. When the front side of the pipeline module placed on the fork arm 302 is in contact with the rear side of the telescopic structure 406, and the telescopic structure 406 is vertically distributed, the front side of the telescopic structure 406 is in contact with the inner front wall of the through groove 405. For example... Figure 1 , Figures 3-7 As shown, under normal circumstances, the baffle 403 is tilted upwards from front to back under the elastic action of several compound torsion springs 404. In actual application, by lowering the height of the rack assembly 3 and pushing the entire lifting device toward the area where the pipeline module needs to be lifted, and controlling the fork arm 302 to extend under the stacked pipeline module, the top of the baffle 403 will be subjected to a downward squeezing force converted from the weight of the pipeline module itself. This squeezing force is transmitted to the compound torsion springs 404, causing the compound torsion springs 404 to twist and deform. Correspondingly, the baffle 403 is adjusted from an inclined state to a horizontal state, so as to avoid obstructing the pipeline module from moving backwards along the upper surface of the fork arm 302.

[0023] Furthermore, when the pipeline module is completely detached from the baffle 403, it indicates that the compressive force above the baffle 403 has been removed. At this time, the compound torsion spring 404 releases its stored energy, causing the baffle 403 to return to its original tilted state. At this time, the baffle 403, together with the backing plate 301 in the rack assembly 3, forms a front and rear clamping constraint on the pipeline module, which can effectively prevent the pipeline module from sliding or changing position during the lifting process, enhance the stability of the pipeline module, and reduce the risk of damage to the pipeline module during transportation.

[0024] The telescopic structure 406 added to the rear side of the baffle 403 is used to increase the contact area between the baffle 403 and the front side of the pipeline module.

[0025] More specifically, the compound torsion spring 404 consists of two spring coils 4041, a U-shaped metal strip 4042 connecting the opposite ends of the two spring coils 4041, and an L-shaped metal strip 4043 connecting the opposite ends of the two spring coils 4041. The top of the L-shaped metal strip 4043 is in contact with the bottom surface of the baffle 403. The L-shaped metal strip 4043 increases the contact area with the baffle 403, making it easier to convert the compressive force on the baffle 403 into the torque force of the compound torsion spring 404.

[0026] Example 2 like Figure 4 , Figures 6-7As shown, the swing angle range of baffle 403 is between 0° and 30°. When baffle 403 is arranged horizontally, its top surface is at the same height as the top surface of fork arm 302, ensuring the pipeline module remains stable when pushed from front to back along fork arm 302. Additionally, when baffle 403 is arranged horizontally, the rear side of telescopic structure 406 fits against the inner rear wall of through groove 405, limiting the baffle 403 and preventing it from continuously tilting downwards, thus exceeding the force range of the compound torsion spring 404. Furthermore, compared to a single torsion spring, the compound torsion spring 404 can distribute the load more evenly, reducing the failure or fatigue of a single torsion spring due to overload, while simultaneously providing a larger torsional torque, resulting in a stronger elastic response capability over a wider range.

[0027] Example 3 The supporting structure 401 includes a supporting base plate 4011, with side plates 4012 fixed to both sides of the supporting base plate 4011. A positioning shaft 402 is installed between the two side plates 4012. A mating platform 4013, matching the number of compound torsion springs 404, is installed at the bottom of the supporting base plate 4011. U-shaped metal strips 4042 are fitted onto the mating platform 4013. Figure 4 and Figure 7 As shown, the docking platform 4013 passes through the U-shaped metal strip 4042, using its own misaligned area to support the U-shaped metal strip 4042. This ensures that the height and horizontal position of the U-shaped metal strip 4042 remain unchanged when the compound torsion spring 404 is subjected to external force, thus avoiding affecting the storage of external force by the compound torsion spring 404. In addition, since the top surface of the docking platform 4013 is in contact with the bottom surface of the baffle 403 when it is arranged horizontally, the multiple docking platforms 4013 can provide sufficient support for the horizontally arranged baffle 403, preventing it from continuously tilting downwards and exceeding the force range of the compound torsion spring 404.

[0028] Example 4 A groove is provided on the rear side of the baffle 403, and a connecting shaft 4031 is installed between the inner walls of the two sides of the groove. The telescopic structure 406 includes a channel plate 4061 inserted into the through groove 405. Two bottom brackets 4062 are installed at the bottom of the supporting base plate 4011, and the front and rear inner width of the bottom brackets 4062 is the same as the width of the through groove 405. Both sides of the channel plate 4061 are rotatably connected to sliding pins 4063 inserted into the bottom brackets 4062. An extension plate 4064 is slidably connected inside the channel plate 4061, and the extension plate 4064 is sleeved on the connecting shaft 4031.

[0029] Combination Figures 3-7As is known, the base bracket 4062 limits the range of forward and backward sliding of the slide column 4063. Simultaneously, the distance between the bottom wall of the base bracket 4062 and the bottom surface of the supporting base plate 4011 is consistent with the diameter of the slide column 4063, ensuring that the channel plate 4061 and the slide column 4063 will not move downwards under their own weight. The slide column 4063, under external force, can rotate and slide forward or backward within the base bracket 4062, thereby controlling the overall movement of the channel plate 4061 and the extension plate 4064 along the through groove 405. Combined with the rotational connection between the extension plate 4064 and the connecting shaft 4031, and the adjustability of the overall height between the extension plate 4064 and the channel plate 4061, the extension plate 4064 and the channel plate 4061 can adjust their position and overall height when the baffle 403 is adjusted between tilted and horizontal states.

[0030] Following the first embodiment described above, when the baffle 403 is rotated along the positioning shaft 402 from a horizontal position to an inclined position, the rear position of the baffle 403 will move slightly forward in terms of planar angle. Since the baffle 403 only changes from a horizontal position to an inclined position under the action of the compound torsion spring 404 when the pipeline module gradually moves backward from being pressed against the baffle 403 until it is detached from the baffle 403, the rear of the inclined baffle 403 usually forms a certain gap with the front of the pipeline module. Therefore, the clamping and restraining effect on the pipeline module is not ideal.

[0031] Based on the above, in this embodiment, as Figure 5 and Figure 7 It is known that the back sides of the extension plate 4064 and the groove plate 4061 are on the same vertical plane, and this vertical plane is located behind the baffle 403. Therefore, the thickness of the extension plate 4064 that exceeds the back side of the baffle 403 will fill the gap formed between the back side of the baffle 403 and the pipeline module. When the baffle 403 is adjusted to be tilted upward from front to back, the back side of the extension plate 4064 is in a close fit with the front side of the pipeline module, thus effectively improving the clamping and limiting effect on the pipeline module.

[0032] Example 5 like Figure 1 , Figure 2 and Figure 6As shown, each of the two fork arms 302 has a slot 3021 and an inner groove 3022 on its opposite side. A threaded screw 3023 is rotatably connected inside the slot 3021, and a dial 3024 connected to the threaded screw 3023 is located inside the inner groove 3022. A slider 3025 connected to the support structure 401 is sleeved on the threaded screw 3023. The slots 3021 and inner grooves 3022 allow the threaded screw 3023 and dial 3024 to be arranged in a concealed manner, avoiding conflict with the related structures of the limiting component 4. In addition, by synchronously rotating the two dials 3024, the threaded screw 3023 is controlled to rotate in a set direction, which in turn controls the slider 3025 to move the limiting component 4 along the front-back axial direction. This allows the position of the limiting component 4 between the two fork arms 302 to be adjusted according to the width of the pipeline module. This effectively improves the adaptability of the limiting component 4 to clamping and limiting pipeline modules of various sizes.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
