Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary lifting equipment, in particular to a cable turntable transfer device. Background Art

[0002] When cables need to be transported, a turntable is usually used. The turntable includes a storage tube and trays on both sides of the tube. The cables can be wound around the tube and then transported on the turntable. However, after storing the cables, the overall weight of the turntable is extremely large. Taking a turntable with cables as an example, the weight of a turntable with high-voltage power cables may reach hundreds of kilograms, and when fully loaded with relatively light low-pressure cables, the overall weight of the turntable will also reach tens of kilograms.

[0003] Normally, when transferring a turntable, it is necessary to avoid rolling the turntable directly to avoid damaging the cables on it. Therefore, large lifting equipment such as gantry cranes are required for transfer work. However, large lifting equipment such as gantry cranes occupy a large area and are not flexible enough. They are difficult to handle in a small range and short distance, especially when transferring on the path from the transport vehicle to the inside of the factory. Therefore, a flexible and convenient transfer auxiliary device suitable for short-distance transfer of turntables is urgently needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cable turntable transfer device, which can assist construction workers in transferring heavy turntables over a short distance.

[0005] The utility model is realized through the following technical solutions.

[0006] A cable turntable transfer device, characterized in that it comprises a load-bearing part and lifting parts arranged at both ends of the load-bearing part;

[0007] Wherein, the load-bearing part includes two load-bearing rods arranged in parallel, and the length of the load-bearing rods exceeds the width of the turnover plate; the width of the turnover plate refers to the distance between the outer side surfaces of the trays on both sides.

[0008] The lifting part includes two groups of lifting frames, and the lifting frames include telescopic frames, load-bearing rods for controlling the extension and retraction of the telescopic frames, a plurality of moving wheels arranged at the bottom of the telescopic frames, and mounting parts arranged at both ends of the telescopic frames. The two mounting parts on a single lifting frame are respectively installed and connected to one end of each of the two hydraulic rods, so that the extension and retraction direction of the telescopic frame is perpendicular to the axial direction of the load-bearing rod.

[0009] The specific operation process of the cable turntable transfer device is as follows:

[0010] First, place two sets of lifting frames on both sides of the pallet on the turntable so that the telescopic direction of the lifting frames is perpendicular to the axial direction of the turntable; then adjust the telescopic frames on the lifting frames to the longest length. Place two load-bearing rods whose length exceeds the width of the turntable on the lifting frames. Since the telescopic direction of the lifting frames is perpendicular to the axial direction of the load-bearing rods, the axial direction of the load-bearing rods is parallel to the axial direction of the turntable. The two ends of each load-bearing rod are respectively placed in the mounting parts of the two lifting frames. Then, the fixed installation between the lifting part and the load-bearing part is completed through the mounting part.

[0011] Then, the length of the telescopic frame is reduced by the hydraulic rod, and the two load-bearing rods on it are driven closer together. In the process of the two load-bearing rods approaching each other, they will collide with the pallet of the turnover plate. If the load-bearing rod is a cylindrical rod, its arc surface naturally forms a guiding structure, and as the distance between the two load-bearing rods decreases, the pallet is guided to move upward. If the load-bearing rod is a rectangular rod or a special-shaped tube, the guiding slope needs to be facing the pallet, and the pallet is guided to move upward and finally supported by the two load-bearing rods.

[0012] Finally, the turnover plate is placed above the gap between the two load-bearing rods and supported by the load-bearing rods. At this time, since there are moving wheels under the telescopic frame, the construction workers can move the turnover plate by pushing it without causing the turnover plate to roll over, thus avoiding damage to the pallet. After reaching the corresponding position, the pressure in the hydraulic rod can be removed to make the gap between the two load-bearing rods larger again, and the turnover plate can be lowered, completing the corresponding transfer work.

[0013] As a further improvement of the present invention, a plurality of pin holes are provided on the telescopic frame. When the telescopic frame is contracted to a desired length, suitable safety pins are inserted into the pin holes to prevent the telescopic frame from suddenly extending to its longest state and causing the turntable supported thereon to suddenly fall down due to failure of the hydraulic rod during practical use.

[0014] As a further improvement of the utility model, the load-bearing rod is a cylindrical rod, and a rotating ring is sleeved on the outer wall of the load-bearing rod for contacting the turnover plate. When the two load-bearing rods collide with the tray and continue to approach, the rotating ring can rotate around the cylindrical load-bearing rod, reducing the friction between the edge of the tray and the load-bearing rod, so that the lifting process of the turnover plate is less obstructed.

[0015] As a further improvement of the utility model, the rotating ring is movably sleeved on the load-bearing rod, and a limiting groove is provided on the rotating ring, and guiding slopes are provided on both sides of the limiting groove. Under this structure, the width of the selected rotating ring can be a style that is larger than the width of the pallet. When carrying out the shipping work, first move the rotating ring to the vicinity of the pallet. After the two load-bearing rods are close to each other so that the rotating ring contacts the pallet, the rotating ring will be driven to move in the axial direction of the load-bearing rod through the guiding slope, and the edge of the pallet will be driven to embed into the limiting groove. The turnover plate is prevented from being offset relative to the load-bearing rod during the transportation process. Even if an offset occurs, only friction occurs between the inner wall of the rotating ring and the load-bearing rod, and the pallet of the turnover plate will not be damaged.

[0016] As a further improvement of the utility model, it also includes a limiting portion for fixing the relative position between the lifting frame and the load-bearing rod to prevent the lifting frame from deviating along the axial direction of the load-bearing rod.

[0017] During the transportation of the turntable, the moving direction is relatively changeable, and the limiting portion can further prevent the lifting frame from moving along the axial direction of the load-bearing rod during the process, thereby causing the load-bearing rod to fall off the mounting portion.

[0018] As a further improvement of the present invention, the limiting part includes a first limiting through hole provided on the load-bearing rod and a limiting rod matched with the first limiting through hole. When the limiting rod passes through the first limiting through hole, the relative position between the lifting frame and the load-bearing rod will be fixed.

[0019] As a further improvement of the present invention, the mounting part includes a mounting base and an upper limit positioning part whose one end is movably connected to the mounting base. Under this structure, the upper limit positioning part can rotate and move around the movable connection point. When the other end of the upper limit positioning part is away from the mounting base, it is convenient to place the load-bearing rod on the mounting base. After the placement is completed, the upper limit positioning part is rotated so that the other end of the upper limit positioning part is in contact with the mounting base, thereby completing the preliminary installation of the mounting part.

[0020] The mounting base is provided with a limiting recess for accommodating one end of the limiting rod, and the upper limiting portion is provided with a second limiting through hole adapted to the limiting rod. When the mounting portion completes the preliminary installation of the load-bearing rod, the first limiting through hole is connected with the second limiting through hole, and one end of the limiting rod is placed in the limiting recess after passing through the second limiting through hole and the first limiting through hole.

[0021] Under this structure, after the limit rod is installed, it not only limits the displacement of the load-bearing rod in the horizontal direction, but also prevents the upper limit portion from rotating, thereby fixing the upper limit portion.

[0022] As a further improvement of the present invention, the moving wheel is a spherical wheel group, and a single spherical wheel group includes a main shell and a plurality of spherical wheels installed in the main shell. If a universal wheel or the like is used as the moving wheel, in the process of changing the shipping direction, it is first necessary to drive the mounting rod of the universal wheel and the wheel body to rotate to facilitate subsequent propulsion. Therefore, in the overall process of steering, it is necessary not only to overcome inertia, but also to overcome the steering resistance generated in the structure such as the universal wheel. The spherical wheel can bring smaller steering resistance, making the steering process of the turntable more flexible and easy.

[0023] As a further improvement of the utility model, a positioning baffle is provided on the telescopic frame, and when the load-bearing part and the lifting part are combined, the positioning baffle contacts the tray of the turntable, thereby further preventing the turntable from deflecting on the cable turntable transfer device during the transfer process.

[0024] As a further improvement of the utility model, the hydraulic rod controls the pressurization work through an electric drive device. On the one hand, the manpower loss of construction workers is reduced during pressurization; on the other hand, the electric drive device is more convenient and accurate to control. Preferably, the same controller can be used to control the hydraulic rods on the two sets of lifting frames at the same time, so that the lifting heights of the two sides of the turnover plate are consistent, so as to prevent the turnover plate from overturning during the lifting process.

[0025] The beneficial effects of the utility model include:

[0026] (1) The structure of the cable turntable transfer device is relatively simple, and the operation is relatively convenient and quick; the installation and disassembly between the components is convenient, which is convenient for the maintenance and replacement of the components; the corresponding size of the load-bearing rod can be selected according to the actual width of the turntable, and the overall applicability of the transfer device is relatively wide;

[0027] (2) After the turnover plate is lifted, the construction workers need less driving force to push it for transfer, which reduces the manpower loss and improves the efficiency of transfer work;

[0028] (3) The process of lifting and lowering the turntable using the transfer device is relatively smooth, and wear between the pallet and the load-bearing rod of the turntable can be avoided during the transfer process, thereby preventing the turntable from being damaged during the transfer process.

[0037] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0038] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0039] Embodiment 1:

[0040] like Figures 5 and 6 As shown, the turntable A includes a tray A01 structure on both sides. The cable turntable transfer device is placed at the bottom of the tray A01 and lifts the turntable A as a whole through structural changes, and then carries out the transfer work.

[0041] like Figure 1~2 and Figure 6 As shown, the transfer device includes a load-bearing part 1 and a lifting part 2. The load-bearing part 1 is used to directly contact the pallet A01 and support the turnover plate A when it is lifted. The lifting part 2 lifts the turnover plate A by adjusting the structure of the transfer device, so the lifting part 2 needs to provide a larger lifting force.

[0042] like Figure 3~4 and Figure 6 As shown, the load-bearing part 1 includes two load-bearing rods 101 , and the length of the load-bearing rods 101 exceeds the width W of the turnover plate A. Therefore, the load-bearing rods 101 of the required size can be replaced according to the width W of the turnover plate A.

[0043] like Figure 1 and Figure 4As shown, the lifting part 2 includes two sets of lifting frames 201, and a single lifting frame 201 includes a telescopic frame 201-1, a hydraulic rod for controlling the telescopic function of the telescopic frame 201-1, a plurality of moving wheels 201-2 arranged at the bottom of the lifting frame 201, and a mounting portion 201-3 arranged at both ends of the telescopic frame 201-1. In this embodiment, a single lifting frame 201 includes two moving wheels 201-2, which are arranged at the bottom of the telescopic frame 201-1 near both ends.

[0044] The mounting portion 201-3 is used to mount the load-bearing rod 101 on the lifting frame 201, and is mainly used to prevent the load-bearing rod 101 from being displaced along the telescopic direction of the telescopic frame 201-1. Specifically, the mounting portion 201-3 can adopt a clamp-type fixing structure, a mechanical locking fixing structure, and the like.

[0045] When using the transfer device, first place the two sets of lifting frames 201 on both sides of the turntable A, and adjust the telescopic frame 201-1 to extend its length to the maximum. Place one end of the load-bearing rod 101 on the mounting portion 201-3 and install it. Figure 3 As shown, the two load-bearing rods 101 are parallel to each other and to the axial direction of the turnover plate A; the telescopic direction of the telescopic frame 201-1 is perpendicular to the axial direction of the load-bearing rod 101, that is, in this embodiment, perpendicular to the axial direction of the turnover plate A. Only when the above directions are accurate can it be ensured that the turnover plate A will not tilt during the lifting process, thereby preventing accidents such as overturning.

[0046] The hydraulic rod includes a hydraulic rod body, an oil cylinder, a connecting structure, an oil unloading valve, etc. The composition of the hydraulic rod is a mature prior art, so it will not be repeated in this embodiment. After the installation between the lifting part 2 and the load-bearing part 1 is completed, the telescopic frame 201-1 is retracted by the hydraulic rod. During the retraction of the telescopic frame 201-1, the two load-bearing rods 101 at both ends will also be driven closer. When the two load-bearing rods 101 are close to a certain distance, they will conflict with the pallet A01. Then, the telescopic frame 201-1 will provide a greater force to continue to cause the telescopic frame 201-1 to retract, and then after the load-bearing rod 101 contacts the pallet A01, the load-bearing rod 101 will guide the pallet A01 to move upward along the outer wall of the load-bearing rod 101. And finally, the transfer device is placed as a whole at the bottom of the turnover plate A, such as Figures 5 and 6 Among them, the load-bearing part 1 plays the role of supporting the turnover plate A.

[0047] Subsequently, since the bottom of the lifting part 2 is provided with a moving wheel 201-2, the construction workers can use a small force to push the turnover plate A to move. After the turnover plate A moves to the desired position, the oil pressure in the hydraulic rod is released, which will cause the telescopic frame 201-1 to slowly and steadily unfold, so that the turnover plate A is slowly lowered to complete the transfer process.

[0048] Preferably, if Figure 4 As shown, three pin holes 201-4 are provided on the telescopic frame 201-1. When the telescopic frame 201-1 is retracted to the required length, safety pins are inserted into the pin holes 201-4 to prevent the telescopic frame 201-1 from suddenly extending and unfolding when the hydraulic rod is damaged, so as to avoid the turntable A above it from falling and being damaged.

[0049] Preferably, if Figures 2~4 As shown, the load-bearing rod 101 is a cylindrical rod, and a rotating ring 102 is sleeved on the outer wall of the load-bearing rod 101 for contacting the tray A01 of the turnover plate A. Therefore, when the two load-bearing rods 101 are close to each other and the turnover plate A is lifted, the rotating ring 102 can rotate around the load-bearing rod 101, and the friction between it and the tray A01 is small, so the resistance encountered when lifting the turnover plate A is reduced. The rotating ring 102 used can be a structure with a large size that covers most of the contact surface of the load-bearing rod 101; or a structure with a small size but larger than the width of the tray A01 can be selected.

[0050] Preferably, if Figure 6 As shown, the rotating ring 102 is movably mounted on the load-bearing rod 101, and the rotating ring 102 can move along the axial direction of the load-bearing rod 101 to adapt to the turnover plates A of different sizes. Before lifting the turnover plate A, the rotating ring 102 needs to be moved to a position close to the pallet A01. A limiting groove 102-1 is provided on the rotating ring 102, and guiding slopes 102-2 are provided on both sides of the limiting groove 102-1. When the guiding slope 102-2 contacts and further approaches the pallet A01, it will drive the rotating plate to move along the axial direction of the load-bearing rod 101, and finally make the limiting groove 102-1 fit with the edge of the pallet A01, thereby completing the positioning of the turnover plate A.

[0051] Embodiment 2:

[0052] The difference between this embodiment and embodiment 1 is that more emphasis is placed on the optimization of the movement process of the turntable A by the transfer device.

[0053] In this embodiment, the transfer device also includes a limiting portion 3. During the transfer process of the turntable A, the change of direction is difficult to predict. When turning, it is necessary to overcome greater resistance. In some usage scenarios, the turntable A may conflict with one of the lifting frames 201 when turning or stopping, and the lifting frame 201 may be driven by inertia to move along the axial direction of the load-bearing roller. In such a case, it is easy for the load-bearing roller to move out of the mounting portion 201-3, which will damage the mounting portion 201-3 on the one hand, and on the other hand, it will cause accidents such as the overturning of the turntable A.

[0054] The setting of the limiting part 3 can further strengthen the fixed position relationship between the fixed load-bearing part 1 and the lifting part 2. The limiting part 3 can be a structure such as a blocking member clamped on the load-bearing pipe at a position further away from the mounting part 201-3.

[0055] Preferably, if Figure 1~2 As shown, the limiting part 3 includes a first limiting through hole 301 provided on the load-bearing rod 101, and a limiting rod 302 adapted to the first limiting through hole 301. The first limiting through hole 301 can be provided on both sides of the contact position with the mounting part 201-3 on the load-bearing rod 101. After the limiting rod 302 is inserted, when the load-bearing rod 101 is displaced relative to the mounting part 201-3, the limiting rod 302 conflicts with the mounting part 201-3 to play a limiting role.

[0056] Preferably, if Figure 1~2 and Figure 5 As shown, the mounting portion 201-3 includes a mounting base 201-3a, and an upper limit positioning portion 201-3b having one end hinged to the mounting base 201-3a. When one end of the load-bearing rod 101 is placed on the mounting base 201-3a, the upper limit positioning portion 201-3b is rotated so that the other end of the upper limit positioning portion 201-3b contacts the mounting base 201-3a, and the first step of installation is completed.

[0057] The mounting base 201-3a is provided with a limiting recess 303 adapted to the limiting rod 302, and the upper limit portion 201-3b is also provided with a second limiting through hole 304 adapted to the limiting rod 302. After the first step of installation is completed, the second limiting through hole 304 is connected to the first limiting through hole 301, and one end of the limiting rod 302 can continuously pass through the second limiting through hole 304 and the first limiting through hole 301, and then be placed in the limiting recess 303.

[0058] Under this structure, the limiting rod 302 not only prevents the load-bearing rod 101 from deviating in the axial direction, but also prevents the load-bearing rod 101 from colliding with the tray A01 and then colliding with the upper limit portion 201-3b, thereby driving the upper limit portion 201-3b to rotate and causing the mounting portion 201-3 to be opened, thereby playing the role of a partial mounting portion 201-3.

[0059] Preferably, if Figure 1 and Figure 7 As shown, the moving wheel 201-2 is a spherical wheel 201-2b group, which includes a main housing 201-2a and four spherical wheels 201-2b installed in the main housing 201-2a. When the moving wheel 201-2 such as a universal wheel changes direction, it is also necessary to overcome the resistance generated when the wheel body and the mounting shaft rotate. When the spherical wheel 201-2b is turning, it does not generate similar resistance. Therefore, after using the spherical wheel 201-2b group, it is smoother to push the turntable A to turn.

[0060] Preferably, a positioning baffle 201-5 is provided on the telescopic frame 201-1. Figure 6 As shown, when the load-bearing part 1 and the lifting part 2 are assembled and support the turnover plate A, the positioning baffle 201-5 conflicts with the tray A01 of the turnover plate A.

[0061] Embodiment 3:

[0062] The difference between this embodiment and embodiments 1 and 2 is that the hydraulic rod controls the pressurization work through the electric drive device. Under this structure, the physical strength of the construction workers consumed during pressurization can be reduced, and when the hydraulic rod pressurization actually acts on the turnover plate A, it is reflected as lifting the turnover plate A. The use of the electric drive device to control can ensure that the lifting height is controllable and accurate, and at the same time, it is also preferred to use a unified controller to control the two sets of lifting frames 201 to ensure that the turnover plate A is lifted horizontally without tipping over.

[0063] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
