Description

Technical Field

[0001] The invention relates to the technical field of textile auxiliary tools, in particular to a spun yarn tube transport vehicle. Background Art

[0002] The spinning frame is the main spinning machine, which is used to stretch, twist and wind the semi-finished roving or sliver into a spinning bobbin during the spinning process. The full bobbin of fine yarn needs to be transported to the automatic winding machine station, where it is made into a large-capacity bobbin, and the defects on the yarn are removed at the same time, so as to provide it for warping, weft supply or bleaching and dyeing processes of the loom. In the traditional bobbin transfer process, the finished fine yarn tube is first placed in a basket manually, and then the basket is manually moved to the unloading trolley at the automatic winding machine, and the unloading trolley is pushed forward along the bottom guide rail of the automatic winding machine in sequence. When passing through each yarn library, the operator puts the bobbin into the yarn library. This transfer method is not only inefficient, but also labor-intensive for the operator.

[0003] The Chinese utility model with authorization announcement number CN 203475004 U discloses a special functional transport vehicle for automatic winding spinning frame and automatic bobbin winder. The transport vehicle has a built-in lifting platform, which is vertically guided and reset by multi-stage scissor arms and compression springs. The transport vehicle is used to store the bobbins, which greatly reduces the number of round trips between the automatic winding spinning frame and the automatic bobbin winder and reduces the work intensity of the operators. When placing the bobbins, the lifting platform and the compression spring are used to keep the operator's grasping height basically consistent each time, which is more convenient and quick, further reduces the difficulty of operation, and improves the work efficiency of the entire process. The transport vehicle with this structural design has been used to this day.

[0004] However, this type of transport vehicle has always had an insurmountable problem in actual use. In order to ensure that the lifting platform can rise and fall smoothly, there is inevitably a gap between the lifting platform and the inner wall of the transport vehicle, and there is also inevitably an installation gap between the moving end of the scissor arm and the slide slot. When workers put the yarn tubes into or take them out of the transport vehicle, since the yarn tubes themselves are heavy, the lifting platform will tilt because one side is subjected to greater force and the other side is subjected to less force. This is not only easy to interfere with the side wall of the transport vehicle and jam the lifting platform, affecting normal use, but also long-term use causes serious deformation of the spring and shortens its service life. The lifting platform is also in a tilted state when it is idle, and the yarn tube always rolls toward the lower side or even falls under the lifting platform, damaging the yarn tube. Summary of the invention

[0005] The purpose of the present invention is to propose a spun yarn tube transport vehicle in view of the deficiencies in the prior art, so as to ensure that the lifting platform can still be lifted and lowered stably when the yarn tubes are unevenly placed, thereby extending the service life.

[0006] The technical solution to achieve the purpose of the present invention is:

[0007] A spun yarn tube transport vehicle comprises a transport trolley and a lifting platform placed inside the transport trolley, wherein an elastic support portion and a lifting guide portion are connected between the lifting platform and the bottom of the transport trolley, wherein the lifting guide portion is provided with two groups and is symmetrically arranged on both sides of the lifting platform, and a synchronization component is transmission-connected between the two lifting guide portions, and the synchronization component is suitable for driving the two lifting guide portions to move synchronously.

[0008] Furthermore, the lifting guide part is a scissor arm, and the two fixed ends on one side of the scissor arm are respectively rotatably hinged with the lifting platform and the transport trolley, and the two free ends on the other side are respectively rotatably connected with the lifting platform and the transport trolley and slidingly connected in the horizontal direction. The synchronization component is connected between the two free ends that are located on the same horizontal plane and can slide to limit the synchronous sliding of the two free ends.

[0009] Furthermore, the synchronization component includes a pair of guide wheels and a pair of reversing wheels respectively arranged on both sides of the bottom of the transport trolley and an annular steel wire rope sleeved between the wheels. The guide wheels and reversing wheels located on the same side are respectively arranged on both sides of the free ends of the corresponding scissor arms. The annular steel wire rope forms a 90° turning angle through the two reversing wheels in turn, so that the annular steel wire rope forms a symmetrical interval with opposite moving directions. The slidable free ends of the two scissor arms are respectively fixed to the upper rope and the lower rope of the annular steel wire rope.

[0010] Furthermore, a slide plate is fixedly installed at the bottom of the transport trolley, and a positioning plate is fitted on the side of the slide plate. The bottom sliding free end of the scissor arm passes through the slide plate through the gap of the sliding bolt pin and is connected to the positioning plate. A pressure block covering the annular steel wire rope is provided on the positioning plate, and the pressure block locks the steel wire rope on the positioning plate through screws to fix the annular steel wire rope to the positioning plate.

[0011] Furthermore, a plurality of the pressing blocks are arranged along the length direction of the annular steel wire rope and are arranged on both sides of the sliding bolt pin shaft.

[0012] Furthermore, the elastic force support part is a spring, and two ends of the spring are respectively fixedly connected to the bottom of the transport trolley and the bottom of the lifting platform.

[0013] Furthermore, the springs are provided in at least four groups, which are respectively located at four corners of the lifting platform.

[0014] Furthermore, the transport trolley and the lifting platform are provided with positioning boxes arranged opposite to each other, the positioning box includes a box body and a positioning ring arranged in the box body, and both ends of the spring are fixedly connected to the transport trolley and the lifting platform through interference sleeves in the positioning ring.

[0015] Furthermore, a strip-shaped hole is provided at the connection between the box body and the transport trolley or the lifting platform plate, and a screw tightened on the transport trolley or the lifting platform plate is provided in the strip-shaped hole.

[0016] Adopting the above technical solution, the present invention has the following beneficial effects:

[0017] (1) By adding a synchronization component in the present invention, the lifting guide parts on both sides can move synchronously. When the force on any one side of the lifting platform plate is greater than that on the other side, the lifting platform plate can still maintain balance, effectively preventing the jamming phenomenon of the lifting platform plate and prolonging the service life of the entire spinning tube transport vehicle.

[0018] (2) The present invention uses scissor arms as the lifting guide parts, with a simple structure. By restricting the synchronous sliding of the free ends of the two scissor arms that can slide through the synchronization component, the synchronous lifting of the tops of the two scissor arms can be achieved.

[0019] (3) The present invention cleverly uses an annular steel wire rope, guide wheels and a reversing wheel to form a pulley block, and connects the free ends of a pair of sliding scissor arms to the upper rope and the lower rope respectively to achieve synchronous movement at both ends, with a simple structure, low manufacturing cost and stronger practicability.

[0020] (4) The present invention uses a pressing block and a positioning plate structure to connect the free end of the scissor arm to the steel wire rope, with a simple structure and convenient disassembly and assembly.

[0021] (5) By arranging a plurality of pressing blocks in the present invention, the connection strength with the steel wire rope is improved.

[0022] (6) The present invention uses springs as the elastic support parts, which are respectively arranged at the four corners of the lifting platform plate to provide better support for the lifting platform plate and further improve the balance of the lifting platform plate.

[0023] (7) By arranging an adjustable positioning box to connect the springs in the present invention, it is not only convenient for assembly, but also convenient for adjustment to ensure that the upper and lower ends of the springs are aligned, not easily distorted, and achieve better elastic support.

DETAILED DESCRIPTION

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] (Example 1)

[0034] like Figures 1 to 5 The spun yarn tube transport vehicle shown includes a transport trolley 1 and a lifting platform 2 placed in the transport trolley 1. An elastic support part 3 and a lifting guide part 4 are connected between the lifting platform 2 and the bottom of the transport trolley 1. The lifting platform 2 with the bobbin placed thereon is supported by the elastic support part 3. When the bobbin is taken out manually, the weight is reduced, the pressure on the elastic support part 3 is reduced, and the lifting platform 2 is gradually reset, driving the lifting platform 2 to rise, so that the height of the worker grabbing the bobbin each time is basically the same, which is more convenient and quick, and reduces the bending amplitude of the worker, improves the work efficiency of the whole process, and reduces the labor intensity of the worker. The lifting guide part 4 is provided with two groups and symmetrically arranged on both sides of the long direction of the lifting platform 2, so as to provide guidance for the lifting and lowering of the lifting platform 2, so that the lifting platform 2 keeps balance. Since the two lifting guide parts 4 work independently, when the lifting platform 2 is unevenly pressed, it will tilt. For this reason, in this embodiment, a synchronous component 5 is connected between the two lifting guide parts 4 in a transmission manner, and the two lifting guide parts 4 are driven to move synchronously by the synchronous component 5, thereby ensuring the balance of the lifting platform.

[0035] Specifically, the lifting guide part 4 is a scissor arm. This embodiment adopts a single-layer scissor arm structure to form four endpoints, namely 4a, 4b, 4c and 4d. The two fixed ends 4a and 4b located at the top and bottom of the right side are respectively rotatably connected to the lifting platform 2 and the transport trolley 1 through an axle hole structure. The front and rear sides of the bottom of the transport trolley 1 are symmetrically fixed with slide plates 1-1. The two 4d at the bottom of the left side pass through the slide plate 1-1 through the sliding bolt pin shaft 9, so as to realize rotation with the transport trolley 1 and sliding connection in the horizontal direction. The free end 4c adopts the same structure to be connected to the lifting platform 2, thereby realizing the lifting and guiding function.

[0036] The synchronization component 5 is connected between two free ends that are located on the same horizontal plane and can slide. Considering the convenience of installation, in this embodiment, the synchronization component 5 is connected between the free ends 4d of two scissor arms to limit the synchronous sliding of the two free ends. Specifically, the synchronization component 5 includes a pair of guide wheels 5-1 and a pair of reversing wheels 5-2 respectively arranged on both sides of the bottom of the transport trolley, and an annular steel wire rope 5-3 sleeved between the two guide wheels 5-1. The guide wheel 5-1 is a single pulley, rotatably installed on the transport trolley 1, and the rotation axis is horizontally arranged. The reversing wheel 5-2 is a double pulley, rotatably installed on the transport trolley 1, and the rotation axis is vertically arranged. The two reversing wheels 5-2 are respectively located at the two left corners of the transport trolley 1. The guide wheel 5-1 and the reversing wheel 5-2 on the same side are respectively arranged on both sides of the free end 4d of the scissor arm. The annular steel wire rope 5-3 forms a 90° turning angle through the two reversing wheels in sequence, forming a U-shaped double-layer rope with an opening facing right.

[0037] Positioning plates 6 are respectively and fittingly arranged on the sides of the two chute plates 1-1 on the transport trolley 1. The bottom free end 4d of the scissor arm is connected to the positioning plate 6 after passing through the chute plate through a sliding bolt pin in a clearance manner. A pressing block 7 covering the annular steel wire rope is arranged on the positioning plate 6. The pressing block 7 is locked to the positioning plate 6 by screws to fix the annular steel wire rope to the positioning plate. In this embodiment, the free end 4d at the front side of the transport trolley is connected to the upper rope of the annular steel wire rope through the pressing block 7, and the free end 4d at the rear side of the transport trolley is connected to the lower rope of the annular steel wire rope through the pressing block 7. When one of the free ends 4d moves, the other free end 4d will also move the same distance synchronously, so as to realize the synchronous action of the two scissor arms. The structure is simple, the manufacturing cost is low, and the practicability is stronger. In order to ensure the connection strength between the annular steel wire rope and the positioning plate 6, a plurality of pressing blocks 7 are arranged along the length direction of the annular steel wire rope and are arranged on both sides of the sliding bolt pin.

[0038] The elastic support part 3 is a spring, and the two ends of the spring are respectively fixedly connected to the bottom of the transport trolley 1 and the bottom of the lifting table board 2. In order to further improve the balance when the lifting table board 2 is unevenly stressed, four groups of springs are provided in this embodiment, and are respectively located at the four corners of the lifting table board 2. Positioning boxes 8 are arranged oppositely on the transport trolley 1 and the lifting table board 2. The positioning box 8 includes a box body 8-1 and a positioning ring 8-2 arranged in the box body 8-1. The two ends of the spring are fixedly connected to the transport trolley 1 and the lifting table board 2 by being press-fitted on the positioning ring 8-2. A strip-shaped hole 8-1-1 is provided at the connection between the box body 8-1 and the transport trolley 1 or the lifting table board 2. Screws tightened on the transport trolley 1 or the lifting table board 2 are arranged in the strip-shaped hole 8-1-1 to realize adjustable installation, which is not only convenient for assembly, but also can ensure that the upper and lower ends of the spring are aligned, not easily twisted and deformed, and realize better elastic support.

[0039] For the convenience of installing the lifting table board 2, in this embodiment, lifting rings 2-1 are provided at the diagonals of the upper surface of the lifting table board 2, which are convenient for the crane to connect and lift, thus facilitating the installation.

[0040] By adding a synchronization component 5 in the present invention, the lifting guide parts 4 on both sides can move synchronously. When any side of the lifting table board 2 is subjected to a large force, the balance can still be maintained, and the service life of the entire spinning tube transport vehicle is prolonged.

[0041] In the specific embodiments described above, the purpose, technical solution and beneficial effects of the present invention have been further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
