Description

Technical Field

[0001] The utility model belongs to the technical field of wire reel feeding trolleys, and particularly relates to a full-automatic wire reel feeding docking trolley. Background Art

[0002] Cable reels are used to store cable reels, and are mainly used for winding and unwinding cables.

[0003] When loading the cable reel, it needs to be moved to the position of the reel's support frame, then raised to the height of the installation point on the support frame, and then installed.

[0004] Currently, most wire reels are transported using hoisting equipment. During this process, the hoisting equipment is used to lift the wire reel to a certain height above the ground. The hoisting equipment then uses a crane to move the wire reel to the mounting position of the carrier frame. The hoisting equipment is then used to raise the height of the wire reel again to align it with the carrier frame. However, using hoisting equipment to transport wire reels has the following problems:

[0005] First, the hoisting equipment uses a lifting rope to lift the cable drum. During the movement of the cable drum, the lifting rope is prone to shaking. Therefore, during the movement of the cable drum, in addition to the lifting equipment operator, additional personnel are required to pull the cable drum to prevent it from shaking significantly during the movement. This process requires a large number of personnel, and the shaking of the cable drum during movement is prone to collision with equipment in the factory area.

[0006] Secondly, when using a lifting rope to raise the height of the wire reel, the wire reel is prone to shaking, which makes it more difficult to align the wire reel with the support frame, and increases the difficulty of subsequent assembly of the wire reel; therefore, this application proposes a fully automatic wire reel docking trolley. Utility Model Content

[0007] The purpose of the utility model is to provide a fully automatic thread reel docking trolley to solve the problems raised by the above background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fully automatic reel docking trolley, comprising a lifting frame, a vehicle body, and a travel track; a clamping unit for clamping and releasing the reel is installed on the lifting frame;

[0009] The lifting frame is connected to the vehicle body through a lifting unit. The lifting unit includes multiple lifts and a lifting power motor. A driving shaft for controlling the hydraulic pressure is provided in the lift. The output shaft of the lifting power motor is connected to the driving shaft through a transmission wheel and a transmission belt. A plurality of tensioning pulleys are installed on the upper side of the transmission belt. The tensioning pulley is rotatably connected to the lifting sleeve through a bearing. The lifting sleeve is inserted into the base. A clamping bolt connected to the base through a thread is provided on the upper side of the lifting sleeve.

[0010] The vehicle body is provided with a driving unit for driving the vehicle body to move along the travel track.

[0011] Preferably, the clamping unit includes two symmetrically distributed side plates, which are respectively located on both sides of the wire drum, and the side plates include a vertical surface and an inclined surface, and the inclined surface is inclined from bottom to top toward the side away from the wire drum.

[0012] Preferably, the clamping unit also includes four clamping blocks, the upper end faces of the clamping blocks are set as inclined surfaces, the clamping blocks are connected to the power rod, the power rod penetrates the support seat, and the side faces of the clamping blocks are interspersed with guide rods, which cooperate with the guide holes in the support seat. The two clamping blocks on the same side are connected through a power plate, and the two power plates are respectively connected to the two output ends of the bidirectional cylinder.

[0013] Preferably, there are four elevators, the driving shafts between two flush elevators are aligned, and two driving shafts of the four elevators are respectively located on both sides of the lifting power motor.

[0014] Preferably, a detection plate is installed on one of the drive shafts, and a measuring mechanism for measuring the number of rotations of the detection plate is installed on the vehicle body.

[0015] Preferably, the driving unit includes a driving motor and a driving gear. The output end of the driving motor is connected to the driving gear. The driving gear cooperates with the rack in the traveling track, and the rack is parallel to the inner wall of the mounting groove in the track plate in the traveling track.

[0016] Preferably, one end of the rack rests on the base plate, the upper end surface of the base plate is rollingly connected to the driving wheel, the center line of the driving wheel is aligned with the center line of the driving gear, and a limiting wheel is provided on the side of the driving wheel away from the driving gear, and the limiting wheel is inserted into the track groove formed by the base plate and the inner wall of the track plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When the utility model is in use, the wire drum is placed on the lifting frame, and a clamping unit for clamping and releasing the wire drum is provided on the lifting frame, which can lock and release the position of the wire drum. The entire vehicle body is driven by the driving unit to move along the travel track. The wire drum is in a stable state during the movement, and four elevators are arranged inside the lifting unit between the vehicle body and the lifting frame. The hydraulic pressure in the four elevators in the lifting unit is controlled by two driving shafts, and the two driving shafts are connected to the lifting power motor through transmission wheels and transmission belts. Therefore, the four elevators are raised and lowered by the same amplitude. Starting the lifting unit can drive the entire lifting frame to rise and fall smoothly. After the wire drum is lifted to the installation height, the wire drum will not be in a stable state, which greatly reduces the operational difficulty of subsequent wire drum installation work.

[0019] 2. The drive unit of the present invention is equipped with driving gears and other components. The driving motor drives the driving gear and the driving wheel to rotate. During this period, the driving gear and the rack cooperate with each other through the teeth to generate power to drive the vehicle body forward and backward, and the driving wheel is rollingly connected to the bottom plate to support the weight of the vehicle body. The energy consumption of the two rolling connections when moving forward and backward is relatively small. When the driving wheel rotates, the limiting wheel moves with it. The limiting wheel is located inside the track groove, and the two are rollingly connected, which can prevent the driving gear and the driving wheel from being displaced in the direction perpendicular to the travel track, and prevent the driving unit from being separated from the travel track. There are two travel tracks and two drive units, and the two are flush and move together, so that the vehicle body is relatively stable during movement.

[0020] 3. When the internal clamping unit of the utility model is started, the internal bidirectional cylinder is started, and its two output ends move, which can drive the two power plates to move closer to or away from each other, thereby clamping and loosening the wire reel between the two through the clamping block, so that it is more convenient to fix the wire reel on the vehicle body or remove it from the vehicle body.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figures 1-9 A fully automatic wire reel docking trolley includes a lifting frame 1, a car body 4, and a travel track 7. The lifting frame 1 is equipped with a clamping unit 3 for clamping and releasing the wire reel 2. When in use, the wire reel 2 is clamped on the lifting frame 1 by the clamping unit 3, and the car body 4 is driven by the driving unit 6 to move to the position where the wire reel 2 is installed.

[0035] Furthermore, the clamping unit 3 includes two symmetrically distributed side plates 301, which are respectively located on both sides of the wire drum 2, and the side plates 301 include a vertical surface and an inclined surface. The inclined surface is inclined from bottom to top toward the side away from the wire drum 2. The wire drum 2 falls from top to bottom through the inclined surface and falls between the two vertical surfaces.

[0036] Specifically, it also includes four clamping blocks 302, the upper end surface of the clamping block 302 is set as an inclined surface, the clamping block 302 is connected to the power rod 303, the power rod 303 penetrates the support seat, and the side of the clamping block 302 is interspersed with a guide rod 304, the guide rod 304 cooperates with the guide hole in the support seat, the two clamping blocks 302 on the same side are connected through a power plate 305, and the two power plates 305 are respectively connected to the two output ends of the two-way cylinder 306; starting the two-way cylinder 306, its two output ends move, which can drive the two power plates 305 to move closer to or away from each other, thereby clamping and loosening the wire drum 2 between the two through the clamping block 302, so that it is more convenient to fix the wire drum 2 on the car body 4 or remove it from the car body 4.

[0037] It should be noted that the lifting frame 1 is connected to the vehicle body 4 through the lifting unit 5. The lifting unit 5 includes four lifts 501 and a lifting power motor 502. The connection line of the four lifts 501 is square-shaped. Two mutually aligned lifts 501 are connected by a drive shaft 504. The output shaft of the lifting power motor 502 is connected to the two drive shafts 504 through a transmission wheel and a transmission belt 503. A plurality of tensioning pulleys 505 are installed on the upper side of the transmission belt 503. The tensioning pulley 505 is rotatably connected to the lifting sleeve 506 through a bearing. The lifting sleeve 506 is inserted into the base 508. The upper side of the lifting sleeve 506 is provided with a clamping bolt 507 that is threadedly connected to the base 508.

[0038] The hydraulic pressure in the four elevators 501 is controlled by two drive shafts 504, and the two drive shafts 504 are connected to the lifting power motor 502 through the transmission wheel and the transmission belt 503. Therefore, the increase range of the hydraulic pressure in the four elevators 501 is the same, and the four elevators 501 are raised and lowered at the same amplitude. Therefore, the entire lifting frame 1 can rise and fall neatly and synchronously. The wire drum 2 on the lifting frame 1 is also relatively stable when rising and falling, and is not easy to shake. In conjunction with the clamping unit 3, it can prevent the wire drum 2 from falling during the movement, rising assembly, and falling process.

[0039] More specifically, a detection plate 509 is installed on one of the drive shafts 504, and a measuring mechanism 510 for measuring the number of rotations of the detection plate 509 is installed on the vehicle body 4; the number of rotations of the detection plate 509 is measured by the measuring mechanism 510 to determine the height to which the elevator 501 is lifted, and the height above which the wire drum 2 rises is the height to which the wire drum 2 rises. The above data serves as a basis for determining whether the wire drum 2 is aligned with the installation point, thereby assisting the wire drum 2 in being aligned with the installation point.

[0040] Furthermore, a driving unit 6 for driving the vehicle body 4 to move along the travel track 7 is installed on the vehicle body 4. The driving unit 6 includes a driving motor and a driving gear 601. The output end of the driving motor is connected to the driving gear 601. The driving gear 601 cooperates with a rack 702 in the travel track 7. The rack 702 is parallel to the inner wall of the mounting groove in the track plate 701 in the travel track 7. One end of the rack 702 is against the bottom plate 703. The upper end surface of the bottom plate 703 is rollingly connected to the driving wheel 602. The center line of the driving wheel 602 is aligned with the center line of the driving gear 601. A limiting wheel 603 is provided on the side of the driving wheel 602 away from the driving gear 601. The limiting wheel 603 is inserted into the track groove 704 formed by the bottom plate 703 and the inner wall of the track plate 701.

[0041] The driving motor drives the driving gear 601 and the driving wheel 602 to rotate. During this period, the driving gear 601 and the rack 702 cooperate with each other through the teeth to generate power to drive the vehicle body 4 forward and backward, and the driving wheel 602 is rollingly connected to the bottom plate 703 to support the weight of the vehicle body 4, and the energy consumption of the two rolling connections when moving forward and backward is relatively small. When the driving wheel 602 rotates, the limiting wheel 603 moves with it, and the limiting wheel 603 is located inside the track groove 704, and the two are rollingly connected, which can prevent the driving gear 601 and the driving wheel 602 from being displaced in the direction perpendicular to the travel track 7, and prevent the driving unit 6 from being separated from the travel track 7. There are two travel tracks 7 and two driving units 6, and the two are flush and move together, so that the vehicle body 4 is relatively stable during movement.

[0042] Working principle:

[0043] Place the wire reel 2 onto the lifting frame 1 using a lifting device and clamp it using the clamping unit 3;

[0044] After that, the driving motor is started, which drives the driving gear 601 and the driving wheel 602 to rotate. During this period, the driving gear 601 and the rack 702 cooperate with each other to generate power to drive the vehicle body 4 forward and backward, and drive the vehicle body 4 to move to the installation position of the wire drum 2;

[0045] After that, the lifting unit 5 is started. The hydraulic pressure in the four elevators 501 in the lifting unit 5 is controlled by two drive shafts 504, and the two drive shafts 504 are connected to the lifting power motor 502 through the transmission wheel and the transmission belt 503. Therefore, the increase range of the hydraulic pressure in the four elevators 501 is the same, that is, the four elevators 501 are raised and lowered by the same amplitude. Therefore, starting the lifting unit 5 can drive the entire lifting frame 1 to rise and fall neatly and synchronously, lift the wire drum 2 to the installation height, and after installing the wire drum 2 at the specified position, release the wire drum 2 through the clamping unit 3, and then start the lifting unit 5 again to drop the lifting frame 1. Finally, start the drive motor to drive the car body 4 to move away from the installation position of the wire drum 2.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
