Description

Technical Field

[0001] This utility model relates to the field of textile production technology, specifically to a spinning yarn transport cart. Background Technology

[0002] In the spinning production process, yarn is usually stored and transported in the form of rolls. In order to achieve efficient flow of yarn rolls between different workstations such as spinning machines, winding machines, and inspection tables, yarn transport trolleys have become an indispensable auxiliary equipment in the workshop. Existing spinning trolleys are manually pushed to transport yarn rolls over short distances. When operating in multiple workshops, there are often thresholds or steps at the workshop entrances with a height difference of 3-8cm. Since all casters are at the same level, when the trolley needs to cross the threshold or step, the bottom of the trolley is prone to a hard impact with the edge of the threshold or step. This not only obstructs the movement of the trolley, but the impact can also cause the roll to come off the support, resulting in the yarn scattering and tangling. Furthermore, since a single roll of yarn can weigh 5-20kg, if the impact force is large or the weight of the roll carried by the trolley is high, the rigidly supported casters are prone to tilting due to uneven force. In extreme cases, this can cause the trolley to tip over, which may damage the yarn roll and pose a safety hazard to the workshop operators. Utility Model Content

[0022] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] like Figure 1-4As shown, a spinning trolley includes a frame, a support column 5, first casters 7, and second casters 8. One end of the support column 5 is connected to the side of the frame, and the other end of the support column 5 is inclined upward. The spinning spool can be fitted onto the support column 5 and abuts against the frame under gravity, making it difficult to detach. There are two first casters 7, each connected to the middle position of the horizontal sides of the lower end of the frame. There are two second casters 8, each connected to the middle position of the vertical sides of the lower end of the frame. The horizontal position of the first casters 7 is higher than that of the second casters 8, forming a movable, seesaw-like lever structure at the bottom of the frame. When the trolley passes over a workshop threshold or step, the second casters 8... With the support of the support, the first caster 7 at the bottom front of the support can be lifted and pass over the threshold or step. After it returns to the ground, the first caster 7 at the bottom rear of the support also lifts and passes over the threshold or step smoothly, achieving unobstructed passage and avoiding phenomena such as the yarn roll coming off or the cart tipping over due to impact with the threshold or step during the transfer process. Since the support column 5 extends to the side, and the first caster 7 is located in the front and rear directions of the support, and the second caster 8 is located in the left and right directions of the support, the direction of movement of the cart is in the front and rear direction when pushing the cart. Even if the cart is bumped, the yarn roll is not easy to come off the support column 5, ensuring the stability and reliability of the transfer. The support frame includes uprights 2, crossbeams 3, and a rectangular bottom frame 1. There are two first casters 7, each connected to the middle of the horizontal sides of the lower end of the bottom frame 1. There are two second casters 8, each connected to the middle of the vertical sides of the lower end of the bottom frame 1. There are two uprights 2, each fixedly connected to the upper ends of the horizontal sides of the bottom frame 1. Multiple crossbeams 3 are vertically spaced between the uprights 2. The uprights 2, crossbeams 3, and bottom frame 1 are all connected by welding. The crossbeams 3 have an isosceles trapezoidal cross-section, facilitating the positioning and installation of the support pillars 5. One end of each support pillar 5 is connected to the side of the crossbeam 3. Multiple support pillars 5 are spaced along the side of the crossbeam 3, providing multiple loading positions for the yarn rolls. The support frame also includes an arc-shaped handle 6. The two ends of the arc-shaped handle 6 are fixedly connected to the upper ends of the two vertical corners of the bottom frame 1. The middle of the arc-shaped handle 6 is fixedly connected vertically to the uprights 2. When transporting yarn, workers can hold the arc-shaped handle 6 to push the cart. When both hands are held simultaneously, the cart is easier to control and the direction is more accurate.

[0024] Each of the four corners of the bottom frame 1 is equipped with an adjustable support foot 14. The lower end of the adjustable support foot 14 can extend downwards beyond the horizontal position of the second caster 8. Each adjustable support foot 14 can be adjusted individually. Two adjustable support feet 14 at the front or rear of the bottom frame 1 can be lowered simultaneously to temporarily touch the ground and stop together with the second caster 8. Alternatively, all four adjustable support feet 14 can be lowered simultaneously when a fixed position is required, so that the trolley can be parked stably in the workshop to avoid accidental collisions or material requisitions. Each of the four corners of the side of the bottom frame 1 is equipped with an arc-shaped channel 102. After material requisition and preparation, the top of the trolley can be covered with a dustproof cloth. The lower end of the dustproof cloth can be hooked into the arc-shaped channel 102 by a buckle to prevent the dustproof cloth from falling off. A baffle 4 is provided between the crossbeam 3 and the support column 5 to support the yarn roll and also to isolate it, preventing the yarn on both sides of the crossbeam 3 from interfering with each other. The baffle 4 can also be made of soft rubber to provide sufficient friction for the yarn roll, preventing it from rotating freely and causing the yarn to unwind, thus preventing the yarn from becoming loose. The support column 2 has through holes on its side, and the crossbeam 3 has threaded posts 301 on both sides. The threaded posts 301 pass through the through holes and are threaded with nuts 15, which abut against the side of the support column 2. The crossbeam 3 and the support column 2 can be connected by assembly, which is convenient and quick, reduces processing difficulty, and improves the consistency of batch manufacturing of the trolley.

[0025] The bottom frame 1 is provided with a sliding groove 101, in which a slider 11 is slidably connected. A second caster 8 is fixedly connected to the lower end of the slider 11. A base plate 10 is provided at the upper end of the sliding groove 101, and a lead screw 12 is threadedly connected to the middle of the base plate 10. The lower end of the lead screw 12 is rotatably connected to the slider 11, and a knob 13 is provided at the upper end of the lead screw 12. The support height of the second caster 8 can be adjusted by the lead screw 12 and the slider 11, thereby adjusting the height difference between the first caster 7 and the second caster 8, and thus adjusting the lever's ability to pry the service and push the cart over obstacles. The support column 5 is threadedly connected to the side of the crossbeam 3, facilitating mass production and quick assembly / disassembly. The bottom frame 1 is provided with a storage basket 9, in which the support column 5 can be detached and placed, facilitating the storage and management of idle or excess support columns 5.

[0026] Description of the working principle of this utility model:

[0027] After the yarn is requisitioned and distributed in production, the yarn is retrieved from the transit warehouse by the personnel of each machine group and loaded onto the support 5 of this trolley. The machine group personnel hold the curved handles 6 with both hands and push the trolley forward from the rear end. When passing a threshold or step, they pull the rear end of the trolley downwards with both hands, causing the first caster 7 at the front of the trolley to leave the ground. The two second casters 8 and the first caster 7 at the rear of the trolley then jointly touch the ground, which is equivalent to using the second casters 8 as a fulcrum to lift the front end of the trolley to cross the threshold or step or other obstacles.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
