Description

Technical Field

[0001] This utility model relates to the technical field of fabric roll production equipment, and in particular to a transport vehicle that facilitates the transfer of fabric rolls. Background Technology

[0002] After the nonwoven fabric is produced, it is stored in the form of a roll. Depending on the application requirements, the nonwoven fabric needs to be flattened, cut and other subsequent processing operations. The subsequent processing needs to be carried out on different processing equipment, so the roll needs to be transferred. The roll is heavy and manual lifting is laborious. Using cranes and other equipment for hoisting is a large investment.

[0003] Chinese patent CN214085757U discloses a fabric roll transfer frame, which has an arc-shaped notch on the crossbar. The fabric roll is placed in the arc-shaped notch for support, preventing the fabric roll from rolling on the transfer frame. A stop bar is provided at the rear end of the crossbar to prevent the fabric roll from rolling off the rear end and causing injury to the operator.

[0004] However, in this patented technical solution, there is no obstruction or limit at the front of the transfer bracket, and the fabric roll may roll off the front of the transfer bracket, which is not safe enough. When transferring fabric rolls of different diameters, if the diameter of the fabric roll does not match the diameter of the notch, the fabric roll will swing back and forth in the notch, further reducing safety. In order to ensure the safety of the transfer bracket, the bottom rollers need to be locked individually when stationary to prevent slippage. When using the transfer bracket to pull the fabric roll, the locking of the rollers needs to be unlocked individually. Each transfer requires operating around the transfer bracket, which increases the number of operation steps. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a transport vehicle for convenient transfer of fabric rolls. By using the weight of the user to press down the pull rod, the support rod lifts the front crossbar. At this time, the front and rear wheels are on the ground, and the transport vehicle can be pulled by the pull rod. After the user leaves the pull rod, the front crossbar descends under the weight of the transport vehicle, the support column touches the ground, and the pull rod tilts up. At this time, the rear wheels and support column support the vehicle body, and the transport vehicle cannot move. As long as the user leaves and no longer pulls the pull rod, the transport vehicle will self-lock and cannot move, thus improving safety.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] A transport vehicle for convenient transfer of fabric rolls includes an I-beam shaped body. The body includes a rear crossbar, a front crossbar, and a longitudinal bar. The two ends of the longitudinal bar are fixedly connected to the inner middle of the opposite sides of the rear and front crossbars, respectively. Support components are provided on the opposite side walls of the rear and front crossbars to support and fix the two ends of the fabric roll shaft. The upper surfaces of the rear and front crossbars are provided with pressing mechanisms to press and fix the two ends of the fabric roll shaft, respectively. Rear wheels are fixedly connected to both ends of the bottom of the rear crossbar, and support columns are fixedly connected to both ends of the bottom of the front crossbar. A lifting rod mechanism is provided in the middle of the bottom of the front crossbar to lift the support column and pull the vehicle body.

[0008] Furthermore, the lifting linkage mechanism includes a top support rod, a steering seat is rotatably connected to the bottom center of the front crossbar, one end of the top support rod is rotatably connected to the steering seat, and a tie rod is fixedly connected to the end of the top support rod away from the steering seat. The tie rod and the top support rod form a certain angle. A front wheel is provided at the end of the top support rod away from the steering seat. The tie rod presses down with the front wheel as the fulcrum to lift the front crossbar with the top support rod.

[0009] Furthermore, the pressing mechanism includes two fixed seats, with a fixed rod fixedly connected between the two fixed seats. The axis of the fixed rod is parallel to the axis of the front crossbar. A movable block is horizontally slidably connected to the fixed rod, and a pressure plate is fixedly connected to the movable block. The pressure plate slides along the fixed rod to the top of the end of the roll shaft to press and fix the roll shaft.

[0010] Furthermore, the vehicle body is equipped with a synchronous adjustment mechanism, which is used to simultaneously drive multiple movable blocks to move away from the longitudinal bar. The synchronous adjustment mechanism includes a slide rod, a front support seat, and a rear support seat. The front support seat is fixedly connected to the top middle of the front crossbar, and the rear support seat is fixedly connected to the top middle of the rear crossbar. The slide rod passes through the front support seat and the rear support seat respectively and is slidably connected to the front support seat and the rear support seat. Several connecting rods are connected to the slide rod. One end of the connecting rod is rotatably connected to the surface of the slide rod, and the other end of the connecting rod is rotatably connected to the movable block.

[0011] Furthermore, a rope is connected to one end of the slide bar near the front crossbar, and the other end of the rope is connected to the middle of the pull rod. A fixing block is fixedly connected to one end of the slide bar near the rear crossbar. The fixing block and the rear support seat are equipped with springs, and the springs are sleeved on the slide bar.

[0012] Furthermore, the support assembly includes two support wheels, which are horizontally arranged and the distance between the two support wheels is less than the diameter of the fabric roll shaft. Limiting wheels are provided on both sides of the support wheels to limit the horizontal sway of the fabric roll shaft.

[0013] Furthermore, the bottom of the support column is equipped with a plastic layer for shock absorption and anti-slip.

[0014] Furthermore, the support components on both the front and rear crossbars are symmetrically distributed along the longitudinal bars.

[0015] Furthermore, the end of the pull rod away from the top support rod is provided with a handle for easy pulling.

[0016] The beneficial effects of this utility model are as follows: when personnel press down the lever, the front and rear wheels support the transport vehicle, facilitating the transfer of fabric rolls. After personnel leave the lever, the transport vehicle is supported by the support column and rear wheels under the action of gravity, achieving self-locking. The transport vehicle will not leave any safety hazards due to the sudden departure of personnel, thus ensuring high safety.

[0017] Both ends of the fabric roll shaft are supported by two support wheels, and limit wheels are also provided on both sides of the fabric roll shaft, which allows the fabric roll shaft to rotate easily to operate the fabric roll, while also providing stable support for the fabric roll. The support components are fixed on the inner sides of the front crossbar and the rear crossbar, directly utilizing the structure of the transport vehicle itself, so the fabric roll shaft cannot move in the axial direction, ensuring stability and safety.

[0018] When the pull rod is pressed down, it pulls the slide bar forward. Under the action of the connecting rod, all the movable blocks move away from the longitudinal bar. The pressure plate on the movable block moves above the end of the roll shaft to prevent the end of the roll shaft from falling off the vehicle when the transport vehicle shakes. When personnel use their weight to press down the pull rod, the clamping mechanism automatically clamps and fixes both ends of the roll shaft to prevent it from falling off. No separate fixing is required, saving time. When transporting to the destination, there is no need to pull the pull rod. The pull rod is lifted, and under the action of the spring, the slide bar returns to its original position, the movable block moves, and the pressure plate moves away from above the end of the roll shaft, making it easy to move the roll.

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in this specification of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. In the following description, the expression "some embodiments" refers to a subset of all possible embodiments; however, it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0025] Combined with reference to the appendix Figures 1 to 4 This utility model provides a transport vehicle for convenient transfer of fabric rolls, including an I-beam shaped vehicle body. The vehicle body includes a rear crossbar 1, a front crossbar 2, and a longitudinal bar 3. The two ends of the longitudinal bar 3 are fixedly connected to the inner middle of the rear crossbar 1 and the front crossbar 2, respectively. Support components are provided on the opposite side walls of the rear crossbar 1 and the front crossbar 2 to support and fix the two ends of the fabric roll shaft 4. The upper surface of the rear crossbar 1 and the front crossbar 2 are provided with a pressing mechanism 13 to press and fix the two ends of the fabric roll shaft 4, respectively. Rear wheels 5 are fixedly connected to the bottom two ends of the rear crossbar 1, and support columns 6 are fixedly connected to the bottom two ends of the front crossbar 2. A lifting pull rod mechanism is provided in the middle of the bottom of the front crossbar 2 to lift the support column 6 and pull the vehicle body. The transport vehicle has an I-beam shaped body, using simple materials. The support components are set on the opposite side walls of the rear crossbar 1 and the front crossbar 2, which can both fix the roll shaft 4 axially and prevent the roll shaft 4 from sliding axially. The support components restrict the horizontal movement of the roll shaft 4. A clamping mechanism 13 is provided above the end of the roll shaft 4 to prevent the roll shaft 4 from jumping up and detaching from the support components due to shaking during the transport of the transport vehicle. When the transport vehicle is stopped and not pulled by personnel, the support column 6 at the bottom of the front crossbar 2 supports the transport vehicle, and the transport vehicle stops smoothly on the ground. When the roll of cloth needs to be transferred, the lifting rod mechanism lifts the front crossbar 2, the support column 6 leaves the ground, and the rear wheel 5 is pulled to move.

[0026] Preferably, the lifting lever mechanism includes a top support rod 8, a steering seat 25 rotatably connected to the bottom center of the front crossbar 2, one end of the top support rod 8 rotatably connected to the steering seat 25, and a pull rod 7 fixedly connected to the end of the top support rod 8 away from the steering seat 25. The pull rod 7 forms a certain angle with the top support rod 8, and a front wheel 9 is provided at the end of the top support rod 8 away from the steering seat 25. The pull rod 7 presses down with the front wheel 9 as the fulcrum to lift the front crossbar 2. When no one pulls the pull rod 7, the support column 6 is on the ground, the top support rod 8 is rotatably connected to the steering seat 25, and the pitch angle of the top support rod 8 can be changed along the connection point. The top support rod 8 does not provide support for the front crossbar 2. When a person pulls the pull rod 7 forward, the top support rod 8, the front wheel 9, and the pull rod 7 form a lever. The plane on which the top support rod 8 and the pull rod 7 are located is perpendicular to the axis of the front wheel. With the pivot of the front wheel 9 as the fulcrum, when the pull rod is pulled forward and downward, the top support rod 8 flips upward, thereby lifting the front crossbar 2. The support column 6 is off the ground and supported by the front wheel 9 on the front crossbar 2, which facilitates the movement of the transport vehicle. When the personnel leave, under the action of gravity, the support column 6 naturally descends with the front crossbar 2 to contact the ground, supporting the front crossbar 2 and preventing the transport vehicle from moving unexpectedly. There is no risk of the transport vehicle moving because the personnel forget to lock the rear wheel 5. The steering seat 25 is rotatably connected to the bottom of the front crossbar 2. When the top support rod 8 lifts the front crossbar 2, it can rotate in the horizontal direction, which facilitates the change of direction of the transport vehicle.

[0027] Preferably, the pressing mechanism 13 includes two fixed seats 16, with a fixed rod 17 fixedly connected between the two fixed seats 16. The axis of the fixed rod 17 is parallel to the axis of the front crossbar 2. A movable block 18 is horizontally slidably connected to the fixed rod 17, and a pressure plate 24 is fixedly connected to the movable block 18. The pressure plate 24 slides along the fixed rod 17 to the top of the end of the fabric roll shaft 4 to press and fix the fabric roll shaft 4. Before placing the fabric roll, the movable block 18 slides towards the longitudinal bar 3, and the pressure plate 24 moves accordingly. After placing the fabric roll, the pressure plate 24 is moved to the top of the end of the fabric roll shaft 4 to prevent the end of the fabric roll shaft 4 from springing up and leaving the support assembly due to the vibration of the transport vehicle, thereby improving the safety of the transport vehicle during the transfer of the fabric roll.

[0028] Preferably, the vehicle body is provided with a synchronous adjustment mechanism 12. The synchronous adjustment mechanism 12 is used to simultaneously drive multiple movable blocks 18 to move away from the longitudinal bar 3. The synchronous adjustment mechanism 12 includes a slide rod 19, a front support seat 15 and a rear support seat 20. The front support seat 15 is fixedly connected to the top middle of the front cross bar 2, and the rear support seat 20 is fixedly connected to the top middle of the rear cross bar 1. The slide rod 19 passes through the front support seat 15 and the rear support seat 20 respectively and is slidably connected to the front support seat 15 and the rear support seat 20. Several connecting rods 21 are connected to the slide rod 19. One end of the connecting rod 21 is rotatably connected to the surface of the slide rod 19, and the other end of the connecting rod 21 is rotatably connected to the movable block 18. The connecting rod 21 is originally rotatably connected to the slide rod 19 in a direction away from the pull rod 7. When the slide rod 19 is pulled towards the pull rod 7, one end of the connecting rod 21 is rotatably connected to the slide rod 19. At this time, that end point moves towards the pull rod 7, and the other end of the connecting rod 21 is rotatably connected to the movable block 18, driving the movable block 18 to move away from the longitudinal rod 3. The movable block 18 is fixedly connected to the pressure plate 24. The pressure plate 24 moves to the top of the end of the roll shaft 4 for pressing and fixing. By pushing and pulling the slide rod 19, the movement of multiple movable blocks 18 is driven simultaneously, saving operation steps.

[0029] Preferably, a rope 14 is connected to one end of the slide bar 19 near the front crossbar 2, and the other end of the rope 14 is connected to the middle of the pull rod 7. A fixing block 22 is fixedly connected to one end of the slide bar 19 near the rear crossbar 1. A spring 23 is provided between the fixing block 22 and the rear support seat 20, and the spring 23 is sleeved on the slide bar 19. When the transport vehicle needs to be moved, the pull rod 7 is pressed down, raising the front crossbar 2, and the front wheel 9 touches the ground. At the same time, as the pull rod 7 is pulled down, the sliding rod 19 is pulled by the rope 14. The sliding rod 19 slides towards the pull rod 7, and the spring 23 between the rear support seat 20 and the fixed block 22 is compressed. The connecting rod 21 drives the movable block 18 to move, so that the pressure plate 24 presses and fixes the two ends of the fabric roll shaft 4. While the pull rod 7 is pulled down, the front crossbar 2 is raised and the two ends of the fabric roll shaft 4 are pressed and fixed, saving operation steps and time. After the transport reaches the destination, the personnel release the handle, the front crossbar 2 falls to the ground, the pull rod 7 tilts upward, and the rope 14 is in a relaxed state. At this time, the spring 23 returns to its original position to push the fixed block 22 away from the rear support seat 20. The sliding rod 19, which is fixedly connected to the fixed block 22, slides away from the pull rod 7, and the movable block 18 moves towards the longitudinal rod 3. The pressure plate 24 no longer presses and fixes the ends of the fabric roll shaft 4, making it convenient for personnel to move the fabric roll.

[0030] Preferably, the support assembly includes two support wheels 10, which are horizontally arranged. The distance between the two support wheels 10 is less than the diameter of the fabric roll shaft 4. Limiting wheels 11 are provided on both sides of the support wheels 10 to limit the horizontal swaying of the fabric roll shaft 4. Each end of the fabric roll shaft 4 is supported by two support wheels 10. The limiting wheels on both sides of the end of the fabric roll shaft 4 further ensure the stability of the end support of the fabric roll shaft 4. The fabric roll shaft 4 has line contact with the two support wheels, resulting in low friction and facilitating the rotation of the fabric roll shaft 4 for operations such as inspecting the fabric roll on the transport vehicle.

[0031] Preferably, the bottom of the support column 6 is provided with a plastic layer to reduce shock and prevent slippage. When the support column 6 touches the ground, it effectively increases friction and prevents the stationary transport vehicle from sliding. When the transport vehicle is pulled to the destination and the lever 7 is released, the plastic layer can also play a role in cushioning and reducing shock when the support column 6 is lowered from a height.

[0032] Preferably, the support components on the front and rear crossbars are symmetrically distributed along the longitudinal bars. This ensures that the weight of the fabric rolls on the transport vehicle is symmetrically distributed along the longitudinal bars 3, improving stability.

[0033] Preferably, the end of the pull rod 7 furthest from the top support rod 8 is provided with a handle for easy pulling. Pulling the pull rod 7 by the handle requires less effort.

[0034] Working principle: Place both ends of the fabric roll shaft 4 on the support wheels 10 for support, press down the pull rod 7, and the top support rod 8 rotates upward, lifting the front crossbar 2 and the support column 6 off the ground. At this time, the transport vehicle is supported by the front wheel 9 and the rear wheel 5. While the pull rod 7 is pressed down, the slide rod 19 is pulled forward through the rope 14, and all the movable blocks 18 move, so that the pressure plate 24 moves to the top of the end of the fabric roll shaft 4 for pressing and fixing, preventing the fabric roll from falling due to shaking during transportation. After the fabric roll is transported to the designated place, release the pull rod 7, and the support column 6 descends to the ground for support. The pull rod 7 rotates upward, and the slide rod 19 slides backward to return to its original position under the action of the spring 23. The movable blocks 18 move, and the pressure plate 24 naturally no longer blocks the end of the fabric roll shaft 4, reducing the operation steps and making it convenient for personnel to move the fabric roll.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model 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 utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
