[0002] Currently, in the production process of enterprises, it is necessary to transfer the thread reels with lead wires between different production processes. The current practice is to manually push the reels to roll on the ground to transfer them. However, this method causes the lead wires wound on the reels to rub against the ground, resulting in scratches and breakage of the lead wires, thus damaging them. In addition, the above transfer method also has the disadvantages of being inconvenient and laborious to transfer the reels. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire reel transport vehicle, which can conveniently realize the transfer of wire reels with lead wire wound on them. It has the advantages of high wire reel transfer efficiency and labor saving. In addition, during the transfer of wire reels, it can avoid the lead wire wound on the wire reel being scratched or broken, that is, it can avoid damage to the lead wire.

[0004] This utility model provides a wire reel transport vehicle, including a frame, a pitch adjustment frame, a lifting frame, and a support frame for carrying the wire reel; a traveling assembly is connected to the bottom of the frame, and a handle is fixed to the rear side of the upper end of the frame; the lower end of the pitch adjustment frame is rotatably connected to the rear side of the frame, and a pitch adjustment structure is provided between the upper end of the pitch adjustment frame and the frame; the lifting frame is vertically slidably connected to the pitch adjustment frame, and a lifting assembly is provided between the lifting frame and the pitch adjustment frame; the support frame is fixed to the front side of the lifting frame; the pitch adjustment structure is used to adjust the pitch angle of the support frame, and the lifting assembly is used to control the lifting and lowering of the support frame.

[0005] This invention can conveniently realize the transfer of spools with leaded wire, and has the advantages of high transfer efficiency and labor saving. In addition, during the transfer of spools, it can avoid the leaded wire on the spool being scratched or broken, that is, it can avoid damage to the leaded wire.

[0006] In one possible implementation, the lower end of the support frame has inwardly bent support edges on both the left and right sides, which are used to support the two ends of the spool in the axial direction. With this structure, when the spool rolls onto the two support edges, the two support edges can support the two ends of the spool in the axial direction, thus enabling the support frame to reliably support the spool.

[0007] In one possible implementation, a crossbar is provided above the two support sides, with both ends of the crossbar welded and fixed to the rear of one of the support sides. The crossbar provides tension to the two support sides, preventing deformation due to the downward pressure from the spool. This ensures reliable support for the spool from both support sides. Furthermore, when the spool rolls onto the two support sides and the support frame tilts from front to back, the crossbar limits the rolling motion of the spool.

[0008] In one possible implementation, a limiting rib is provided laterally at the top of the front end of each support edge; by setting the limiting rib, after the two ends of the spool in the axial direction pass the limiting rib and roll to the corresponding support edge, the limiting rib can prevent the spool from rolling back.

[0009] In one possible implementation, the walking assembly includes two rollers and two casters; the two rollers are symmetrically rotatably connected to the bottom of the front side of the frame, and the two casters are symmetrically connected to the rear side of the frame. The two rollers and two casters are used to support the frame. With this structure, the rollers and casters can reliably support the frame, and the wire reel transporter can reliably move when the operator pulls the handle. In addition, the two casters allow for easy control of the wire reel transporter's direction of travel.

[0010] In one possible implementation, the pitch adjustment structure includes a front rotating seat, a rear rotating seat, a lead screw, a nut sleeve, and an adjusting handwheel. The front rotating seat is rotatably connected to the middle of the upper end of the frame, and the rear rotating seat is rotatably connected to the middle of the upper end of the pitch adjustment frame. The nut sleeve is fixed to the rear rotating seat, the lead screw passes through the nut sleeve and is threadedly connected to it, the front end of the lead screw is horizontally rotatably connected to the front rotating seat, and the adjusting handwheel is fixed to the rear end of the lead screw. With this pitch adjustment structure, operating the adjusting handwheel causes the lead screw to move to one side. During rotation, the screw and nut sleeve work together to move the front rotating seat closer to the rear rotating seat, thus tilting the pitch adjustment frame backward and increasing the pitch angle of the support frame. Similarly, when the adjusting handwheel is operated to rotate the screw to the other side, the screw and nut sleeve work together to move the front rotating seat away from the rear rotating seat, thus rotating the pitch adjustment frame forward and resetting it, thereby decreasing the pitch angle of the support frame. Through the above structure, the pitch angle of the support frame can be easily adjusted.

[0011] In one possible implementation, the pitch adjustment frame is provided with two left-right symmetrical sliding grooves; the lifting frame is horizontally fixed with several support shafts distributed at intervals from top to bottom, and each support shaft is rotatably connected to a first bearing at both ends, and each first bearing can be vertically rolled in the corresponding sliding groove; with this structure, the lifting frame can be reliably vertically slidably connected to the pitch adjustment frame under the cooperation of the first bearings and the sliding grooves.

[0012] In one possible implementation, several second bearings are rotatably connected to the left and right sides of the lifting frame, spaced apart from top to bottom. Each second bearing abuts against the inner wall of the corresponding side's slide groove and rolls in cooperation with the slide groove. By setting the second bearings, since each second bearing abuts against the inner wall of the corresponding side's slide groove and rolls in cooperation with the slide groove, the lifting frame can avoid swaying left and right when it slides vertically relative to the pitch adjustment frame, thus improving the reliability and stability of the lifting frame during lifting.

[0013] In one possible implementation, the lifting assembly includes a lifting hydraulic cylinder, which is vertically fixed to the middle of the lower end of the pitch adjustment frame, and the upper end of the piston rod of the lifting hydraulic cylinder is fixed to the middle of the upper end of the lifting frame. When the pedal of the lifting hydraulic cylinder is stepped on, the piston rod of the lifting hydraulic cylinder is used to lift the lifting frame. When the pressure relief lever of the lifting hydraulic cylinder is pulled, the piston rod of the lifting hydraulic cylinder retracts to lower the lifting frame. By using this lifting assembly, the user can easily control the lifting of the lifting frame, that is, can easily realize the lifting control of the coil located on the support frame.

[0014] In one possible implementation, a ground brake is fixed to the rear side of the bottom of the frame, and the ground brake is located in the middle of the frame in the left-right direction. With this structure, when the wire reel transporter needs to stop, the ground brake can be depressed, thereby stopping the wire reel transporter. When the wire reel transporter is parked, the ground brake can prevent the wire reel transporter from moving randomly after it is depressed. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] See Figure 1-4 As shown in the figure, this application discloses a wire reel transport vehicle, including a frame 1, a pitch adjustment frame 2, a lifting frame 3, and a support frame 5 for carrying wire reels 4; a traveling assembly is connected to the bottom of the frame 1, and a handle 11 is fixed to the rear side of the upper end of the frame 1; the lower end of the pitch adjustment frame 2 is rotatably connected to the rear side of the frame 1, and a pitch adjustment structure is provided between the upper end of the pitch adjustment frame 2 and the frame 1; the lifting frame 3 is vertically slidably connected to the pitch adjustment frame 2, and a lifting assembly is provided between the lifting frame 3 and the pitch adjustment frame 2; the support frame 5 is fixed to the front side of the lifting frame 3; the pitch adjustment structure is used to adjust the pitch angle of the support frame 5, and the lifting assembly is used to control the lifting and lowering of the support frame 5.

[0024] The lower end of the support frame 5 has inwardly bent support edges 51 on both the left and right sides. The two support edges 51 are used to support the two ends of the spool 4 in the axial direction. With this structure, when the spool rolls to the two support edges, the two support edges can support the two ends of the spool in the axial direction, which means that the support frame can reliably support the spool.

[0025] A crossbar 52 is provided above the two support edges 51, and the two ends of the crossbar 52 are welded and fixed to the rear of one of the support edges 51 respectively. With the crossbar, the crossbar can tighten the two support edges, thereby preventing the support edges from deforming due to the downward pressure of the spool. In other words, the two support edges can reliably support the spool. In addition, when the spool rolls onto the two support edges and the support frame tilts from front to back, the crossbar can limit the rolling of the spool.

[0026] Each support edge 51 has a horizontally positioned stop rib 53 at the top of its front end. With the setting of the stop rib, after the two ends of the spool in the axial direction pass the stop rib and roll to the corresponding support edge, the stop rib can prevent the spool from rolling back.

[0027] The walking assembly includes two rollers 61 and two casters 62. The two rollers 61 are symmetrically connected to the bottom of the front side of the frame 1, and the two casters 62 are symmetrically connected to the rear side of the frame 1. The two rollers 61 and the two casters 62 are used to support the frame 1. With this structure, the rollers and casters can reliably support the frame, and the wire reel transporter can move reliably when the operator pulls the handle. In addition, the two casters can be used to easily control the direction of travel of the wire reel transporter.

[0028] The pitch adjustment structure includes a front rotating seat 71, a rear rotating seat 72, a lead screw 73, a nut sleeve 74, and an adjusting handwheel 75. The front rotating seat 71 is rotatably connected to the middle of the upper end of the frame 1, and the rear rotating seat 72 is rotatably connected to the middle of the upper end of the pitch adjustment frame 2. The nut sleeve 74 is fixed to the rear rotating seat 72, the lead screw 73 passes through the nut sleeve 74 and is threadedly connected to the nut sleeve 74, the front end of the lead screw 73 is horizontally rotatably connected to the front rotating seat 71, and the adjusting handwheel 75 is fixed to the rear end of the lead screw 73. By adopting this pitch adjustment structure, when the adjusting handwheel is operated to adjust the pitch... When the adjusting handwheel drives the lead screw to rotate to one side, the cooperation between the lead screw and the nut sleeve causes the front rotating seat to move closer to the rear rotating seat, thus tilting the pitch adjustment frame to the rear and increasing the pitch angle of the support frame. Similarly, when the adjusting handwheel is operated to drive the lead screw to rotate to the other side, the cooperation between the lead screw and the nut sleeve causes the front rotating seat to move away from the rear rotating seat, thus resetting the pitch adjustment frame to the front and decreasing the pitch angle of the support frame. Through the above structure, the pitch angle of the support frame can be easily adjusted.

[0029] The pitch adjustment frame 2 is provided with two left-right symmetrical sliding grooves 21; the lifting frame 3 is horizontally fixed with several support shafts 31 distributed from top to bottom, and each support shaft 31 is rotatably connected to a first bearing 32 at both ends, and each first bearing 32 can be vertically rolled in the corresponding sliding groove 21; with this structure, under the cooperation of the first bearing and the sliding groove, the lifting frame can be reliably vertically slidably connected to the pitch adjustment frame.

[0030] Several second bearings 33 are rotatably connected to the left and right sides of the lifting frame 3, which are spaced apart from top to bottom. Each second bearing 33 abuts against the inner wall of the corresponding slide groove 21 and rolls in cooperation with the slide groove 21. By setting the second bearings, since each second bearing abuts against the inner wall of the corresponding slide groove and rolls in cooperation with the slide groove, the lifting frame can avoid left and right swaying when it slides vertically relative to the pitch adjustment frame, which can improve the reliability and stability of the lifting frame when it is lifting.

[0031] The lifting assembly includes a lifting hydraulic cylinder 8, which is vertically fixed to the middle of the lower end of the pitch adjustment frame 2. The upper end of the piston rod of the lifting hydraulic cylinder 8 is fixed to the middle of the upper end of the lifting frame 3. When the pedal 81 of the lifting hydraulic cylinder 8 is stepped on, the piston rod of the lifting hydraulic cylinder 8 is used to lift the lifting frame 3. When the pressure relief lever 82 of the lifting hydraulic cylinder 8 is pulled, the piston rod of the lifting hydraulic cylinder 8 retracts to lower the lifting frame 3. By using this lifting assembly, the user can easily control the lifting of the lifting frame, that is, can easily realize the lifting control of the coil located on the support frame.

[0032] A ground brake 9 is fixed to the rear side of the bottom of the frame 1. The ground brake 9 is located in the middle of the left and right direction of the frame 1. With this structure, when the wire reel transporter needs to stop, the ground brake can be stepped on to stop the wire reel transporter. When the wire reel transporter is parked, the ground brake can prevent the wire reel transporter from moving randomly after it is stepped on. The above-mentioned ground brake is an existing component on the market and is existing technology, so it will not be described in detail here.

[0033] When using this utility model to transport the wire reel, first move the wire reel transport vehicle to the loading position. Then, adjust the bottom of the support frame to a horizontal state using the tilt adjustment structure. Next, control the lifting component to slide the lifting frame downwards until the lower end of the support frame is supported on the ground. Immediately afterward, depress the ground brake to prevent the wire reel transport vehicle from moving arbitrarily. Then, roll the wire reel with the wire wound onto the two support sides located on the support frame. The limiting ribs on the support sides can prevent the wire reel from rolling back. Then, control the lifting component to slide the lifting frame upwards to an appropriate height, at which point the wire reel can be lifted. Next, the pitch adjustment mechanism is used to adjust the pitch adjustment frame so that the support frame is tilted up at a certain angle to prevent the spool from rolling off the support frame due to inertia when the spool transport vehicle is moving. Finally, the ground brake is released and the spool transport vehicle is moved to the target position. After the spool is transported to the target position, the ground brake is depressed again, and the bottom of the support frame is adjusted to a horizontal state again through the pitch adjustment mechanism. Then, the lifting component is used to control the lifting frame to slide down and finally make the lower end of the support frame support the ground. Then, the spool is pushed to make the spool roll off the support frame, thus realizing the transfer of the spool with the lead wire.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
