Description

Technical Field

[0001] This utility model relates to the field of turnover cart technology, specifically a workshop material turnover cart. Background Technology

[0002] Trolleys are commonly used material handling equipment in workshops and production lines, primarily for short-distance material transfer. Their core structure typically includes a frame to carry materials and braked casters for easy movement. In the workshop production process, trolleys play a crucial role in connecting different processes and transferring materials. Their ease of operation and transfer efficiency directly affect the overall flow rhythm of the production line, making them one of the fundamental pieces of equipment ensuring a stable supply of materials in the workshop.

[0003] The existing workshop turnover carts have many shortcomings in actual use: On the one hand, during the loading and unloading process, there is a lack of effective drag reduction structure between the material boxes and the cart frame. Workers need to manually move the material boxes to or unload them from the cart frame, which not only results in high frictional resistance but also consumes a lot of physical strength and has low operating efficiency. On the other hand, in order to prevent the turnover cart from moving randomly during loading and unloading, workers need to manually operate the caster brake limit, and then manually release the limit after loading and unloading. The operation process is cumbersome and adds extra steps. Throughout the operation, workers need to walk around the cart frame to operate the brakes on the four casters, and walk to the side of the cart frame to move the material boxes from the top of the cart frame to the shelf. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a workshop material turnover cart to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a workshop material turnover cart, including a frame, with a flow strip connected inside the frame; a limit block connected to the upper side of one side of the frame, and a blocking frame connected to the other side of the frame; a guide sleeve connected to the lower back of the frame, and rotating sleeves connected to both sides of the top of the frame, with a pusher connected between the two rotating sleeves; a support foot connected to the bottom of the pusher via a rotating joint, and a tension spring connected between the support foot and the guide sleeve; an operating frame and a counterweight frame connected to both sides of the back of the frame, and a pusher frame connected to the middle inside the frame, with a first pull rope and a second pull rope connected between the pusher frame and the operating frame and the counterweight frame, respectively; and multiple pulleys connected to the back and bottom of the frame.

[0006] By adopting the above technical solutions, the flow strip provides horizontal displacement support for the material box and reduces frictional resistance. The limit block and the blocking frame work together to balance the material box's limiting requirements and the convenience of loading and unloading. The rotating sleeve, guide sleeve, pusher, rotating joint, support foot and tension spring form an automatic braking and limiting mechanism to simplify the operation process. The operating frame, push frame, counterweight frame, pull rope and pulley form an assist unloading and automatic reset structure. All components work together to specifically solve the problems of physical labor required for loading and unloading, cumbersome braking operation and low unloading efficiency of traditional turnover carts, and realize the convenience and efficiency of short-distance material flow.

[0007] Furthermore, the blocking frame has a "C" shaped cross-section and is rotatably connected to the vehicle frame.

[0008] By adopting the above technical solution, the C-shaped cross-section blocking frame can be adapted to the front and rear sides of the material box after rotating back to its original position, forming a stable front and rear limiting effect; and the rotating connection design between the blocking frame and the vehicle frame allows the staff to rotate the blocking frame upward to open it when loading and unloading goods, so as to avoid obstructing the material box from entering and exiting the vehicle frame, thus taking into account both the limiting stability during material transfer and the ease of operation when loading and unloading goods.

[0009] Furthermore, the blocking frame is inclined and abuts against the limiting block.

[0010] By adopting the above technical solution, the contact and cooperation between the blocking frame and the limiting block can accurately limit the maximum angle of the upward rotation of the blocking frame, avoiding excessive rotation that would result in a large operating distance during rotation, or the blocking frame falling back due to gravity because of the lack of a limit, thereby reducing the interference of the blocking frame on the material box entering and leaving the vehicle frame.

[0011] Furthermore, the pusher is rotatably connected to the rotating sleeve, and the rotating joint is slidably connected to the pusher, while the support foot is slidably connected to the guide sleeve.

[0012] By adopting the above technical solution, the pusher can rotate around the rotating sleeve to form a lever structure, providing a fulcrum for the brake release operation; the sliding connection between the rotating joint and the pusher, and the sliding connection between the support foot and the guide sleeve, can effectively compensate for the trajectory conflict between the circular motion of the pusher and the linear motion of the support foot, avoid dead points in motion, and ensure that the support foot can slide smoothly up and down along the guide sleeve, thereby achieving stable release and automatic reset of the brake state without the need for manual operation of the brake components.

[0013] Furthermore, the operating frame, push frame, and counterweight frame are all slidably connected to the vehicle frame via Xingqiantian's GLT28-M-3008J linear rolling assembly.

[0014] By adopting the above technical solutions, Xingqiantian's GLT28-M-3008J linear rolling assembly can significantly reduce the sliding friction resistance between the operating frame, push frame, counterweight frame and the vehicle frame, making the downward movement of the operating frame, the forward and backward displacement of the push frame and the lifting and lowering of the counterweight frame smoother, reducing the physical exertion of the staff when driving the movement of each component, while reducing the sliding wear of the components and extending the service life of the equipment.

[0015] Furthermore, the first and second pull ropes are in contact with multiple pulleys respectively.

[0016] By adopting the above technical solution, the pulley can change the force transmission direction of the first and second pull ropes: the pressure generated by the downward movement of the operating frame can be converted into a pulling force to move the push frame forward after being changed by the pulley; the gravity generated by the downward movement of the counterweight frame can be converted into a pulling force to move the push frame back to its original position after being changed by the pulley, thus realizing efficient force transmission, ensuring the continuous execution of unloading and resetting actions, and improving operational efficiency.

[0017] Furthermore, the first and second pull ropes are high-strength nylon ropes, stainless steel soft ropes, or stainless steel plastic-coated ropes, and both ends of the first and second pull ropes are equipped with safety hooks and Xingqiantian clamp kits.

[0018] By adopting the above technical solutions, high-strength nylon ropes, stainless steel soft ropes, or stainless steel plastic-coated ropes have sufficient tensile strength to withstand the pulling force during unloading, are not easy to break, and ensure the safety of equipment use. The safety hooks at both ends, in conjunction with the Xingqiantian clamp kit, can realize the quick assembly and disassembly of the pull rope with the push frame, operating frame, and counterweight frame. When the pull rope is fatigued, overstretched, or broken, it can be easily replaced, reducing equipment maintenance time.

[0019] Furthermore, four casters are connected to each side of the bottom of the frame.

[0020] By adopting the above technical solution, four casters provide basic mobility for the turnover cart, enabling workers to easily push the turnover cart to move within the workshop, realizing short-distance material transfer from upstream to downstream processes, meeting the core needs of multi-station material transfer within the workshop, and serving as the basic support for the turnover cart to realize its circulation function.

[0021] Furthermore, multiple flow bars are provided, and the multiple flow bars are distributed along a "U"-shaped path.

[0022] By adopting the above technical solutions, multiple flow strips can increase the support points at the bottom of the material box, improving the stability of the material box placement; while the U-shaped path distribution design can conform to the conventional placement and displacement trajectory of the material box, providing comprehensive support for the bottom and sides of the material box, further reducing the contact friction resistance between the material box and the frame, making it smoother for the material box to enter or move out of the frame horizontally.

[0023] Furthermore, the frame, blocking frame, pusher, support foot, operating frame, push frame, and counterweight frame are all assembled from Xingqiantian's lean pipes and Xingqiantian's lean pipe accessories, and the flow strip, casters, limit blocks, rotating sleeves, guide sleeves, rotating joints, tension springs, first pull rope, pulleys, and second pull ropes are all from Xingqiantian's lean pipe accessories or are assembled from multiple Xingqiantian lean pipe accessories.

[0024] By adopting the above technical solutions, Xingqiantian's lean pipes and accessories are all standardized components, eliminating the need for individual customization and processing, facilitating bulk purchasing, and reducing equipment production and procurement costs. When a component is damaged, the corresponding standard part can be purchased directly for replacement without replacing the entire equipment, reducing maintenance costs. At the same time, staff can adjust the lean pipe dimensions (such as frame length and height) or replace different specifications of flow strips according to actual needs, flexibly adapting to material boxes of different sizes and production lines from different manufacturers, improving the equipment's versatility and adaptability.

[0025] In summary, the present invention has the following main advantages: 1. This utility model utilizes a flow strip, limiting blocks, and a blocking frame. The flow strip supports the bottom of the material box and reduces frictional resistance during horizontal displacement within the frame using its roller structure, thus reducing the physical exertion of workers when handling the material box. The limiting blocks restrict the maximum upward rotation angle of the blocking frame, reducing the possibility of the blocking frame obstructing the material box's entry and exit due to excessive rotation or self-falling. After rotating back to its original position, the blocking frame cooperates with the frame to form a limiting structure, i.e., the blocking frame limits the material box in the front-to-back direction, and the frame limits the material box in the left-to-right direction, thereby reducing the probability of the material box shaking or detaching from the frame during transportation. The low resistance facilitates loading and unloading. 2. This utility model, through the arrangement of a rotating sleeve, guide sleeve, pusher, rotating joint, support foot, and tension spring, provides a stable rotational support foundation for the pusher, while the guide sleeve guides the linear sliding of the support foot. When the worker rotates the pusher downwards, the pusher can drive the support foot to slide upwards along the guide sleeve via the rotating joint. During this process, the rotating joint's sliding at the bottom of the pusher and its own rotation can compensate for the conflict between the circular motion of the pusher and the linear motion of the support foot, reducing the occurrence of dead points and thus achieving the effect of the support foot moving upwards to contact the brake. When the worker stops gripping the pusher, the tension spring can pull the support foot to slide downwards along the guide sleeve and fit against the ground, while simultaneously driving the pusher back to a horizontal state. This eliminates the need for the worker to manually operate the brake limit and release steps, reducing the phenomenon of the turnover cart moving arbitrarily during loading and unloading, and simplifying the operation process. It also eliminates the need for the worker to operate the caster brakes while walking around the frame. 3. This utility model, through the arrangement of an operating frame, a first pull rope, a push frame, pulleys, a counterweight frame, and a second pull rope, allows workers to drive the operating frame downwards by hand or foot. The first pull rope, with the help of pulleys, changes the direction of force transmission, pulling the push frame forward and thus pushing the material box from the flow rail towards the warehouse shelf or equipment shelf, reducing the physical exertion of manual handling and unloading. During the forward movement of the push frame, the second pull rope can pull the counterweight frame upwards. When the worker stops applying force to the operating frame, the counterweight frame can begin to move downwards under gravity. The second pull rope pulls the push frame back to its original position, simultaneously driving the operating frame upwards to its original position, preparing for the next unloading. This reduces the number of manual reset steps after unloading and improves unloading efficiency. During unloading, workers do not need to walk to the side of the vehicle frame to move the goods; the vehicle frame can be pushed to fit against the shelf for direct unloading.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A type of workshop material turnover cart, such as Figures 1-7As shown, the system includes a frame 1, with a flow strip 2 connected inside the frame 1. A limit block 4 is connected to the upper side of one side of the frame 1, and a blocking frame 5 is connected to the other side of the frame 1. The blocking frame 5 has a "C"-shaped cross-section and is rotatably connected to the frame 1. The blocking frame 5 abuts against the limit block 4 and is tilted. The operator first rotates the blocking frame 5 upward. When the blocking frame 5 rotates to abut against the limit block 4, the limit block 4 limits the maximum rotation angle of the blocking frame 5 to prevent excessive rotation and keeps the blocking frame 5 tilted upward to prevent it from falling back due to gravity. After the blocking frame 5 rotates upward, it no longer obstructs the material box from entering the frame 1. Subsequently, the operator loads the material box into the frame 1. The material box is pushed to the top of the flow bar 2. Multiple flow bars 2 distributed along the U-shaped path will jointly support the bottom and sides of the material box. The roller structure of the flow bar 2 itself reduces the contact friction resistance between the material box and the frame 1, allowing the material box to move horizontally into the frame 1 more smoothly. After the material box is completely in the frame 1, the staff will rotate the blocking frame 5 back to its original position. Because the blocking frame 5 has a C-shaped cross section, it can limit the front and rear direction of the material box after it is reset. The frame 1 itself limits the left and right direction of the material box. Together with the support of the bottom of the material box by the flow bar 2, the probability of the material box shaking or falling off the frame 1 during subsequent transportation is reduced. A guide sleeve 7 is connected to the lower back of the frame 1. Rotating sleeves 6 are connected to both sides of the top of the frame 1. A pusher 8 is connected between the two rotating sleeves 6, and the pusher 8 is rotatably connected to the rotating sleeves 6. A support foot 10 is connected to the bottom of the pusher 8 via a rotating joint 9, and the rotating joint 9 is slidably connected to the pusher 8. A tension spring 11 is connected between the support foot 10 and the guide sleeve 7, and the support foot 10 is slidably connected to the guide sleeve 7. When the operator rotates the pusher 8 downwards, the pusher 8 begins to rotate downwards around the rotating sleeves 6, using the rotating sleeves 6 on both sides of the top of the frame 1 as its rotational support. Because the bottom of the pusher 8 is connected to the guide sleeve 6... The rotating joint 9 is connected to the support foot 10, and the support foot 10 is slidably connected to the guide sleeve 7 on the back of the frame 1. When the pusher 8 rotates, it will drive the support foot 10 to slide upward along the guide sleeve 7 through the rotating joint 9. During this period, the rotating joint 9 can not only rotate itself, but also slide at the bottom of the pusher 8, thereby compensating for the trajectory conflict between the circular motion of the pusher 8 and the linear motion of the support foot 10, reducing the occurrence of dead points in the motion, ensuring that the support foot 10 can move upward smoothly and leave the ground, thereby releasing the braking state of the turnover cart. Furthermore, the upward movement of the support foot 10 will cause the tension spring 11 to stretch and store force. The back of the frame 1 is connected to the operating frame 12 and the counterweight frame 16 on both sides. A push frame 14 is connected to the center of the frame 1. The operating frame 12, push frame 14, and counterweight frame 16 are all slidably connected to the frame 1 via Xingqiantian's GLT28-M-3008J linear rolling assembly. A first pull rope 13 and a second pull rope 17 are connected between the push frame 14 and the operating frame 12 and counterweight frame 16, respectively. The first pull rope 13 and the second pull rope 17 are high-strength nylon ropes, stainless steel soft ropes, or stainless steel plastic-coated ropes. Safety hooks and Xingqiantian's clamp kits are installed at both ends of the first pull rope 13 and the second pull rope 17. Multiple pulleys 15 are connected to the back and bottom of the frame 1. The first pull rope 13 and the second pull rope 17 are in contact with the multiple pulleys 15. The operator presses the pulleys by hand or... The operating frame 12 is driven to move downward by foot pedal. During the downward movement of the operating frame 12, a pulley 15 on its outer surface presses down the first pull rope 13. The first pull rope 13 changes the direction of force transmission under the action of part of the pulley 15, thereby pulling the push frame 14 in the middle of the frame 1 forward. When the push frame 14 moves forward, it pushes the material box in the frame 1, causing the material box to move along the top of the flow bar 2 towards the warehouse shelf or equipment shelf. This eliminates the need for staff to walk to the side of the frame 1 to manually move the material box, reducing physical exertion during unloading. At the same time, the push frame 14 pulls the second pull rope 17 connected to it during the forward movement. The second pull rope 17 changes the direction of force transmission through another part of the pulley 15, causing the counterweight frame 16 on the other side of the back of the frame 1 to rise and store potential energy.

[0031] See Figure 1 and Figure 2 In the above embodiment, four casters 3 are connected to the bottom sides of the frame 1 respectively. The staff needs to move the turnover cart to the process position to be loaded, such as the shelf or warehouse shelf of the previous process. During the process, the casters 3 at the bottom of the frame 1 are used to realize the flexible movement of the equipment.

[0032] Example 2: Based on the above embodiment one, in order to further reduce resistance, the following settings are now implemented.

[0033] See Figure 1 and Figure 2 In the above embodiment, multiple flow bars 2 are provided, and the multiple flow bars 2 are distributed along a "U" shaped path. The multiple flow bars 2 distributed along the U shaped path will jointly support the bottom and sides of the material box, and the roller structure of the flow bars 2 itself will reduce the contact friction resistance between the material box and the frame 1, allowing the material box to move horizontally into the interior of the frame 1 more smoothly.

[0034] Example 3: Based on the above embodiment one, the following settings are now implemented to facilitate production and subsequent maintenance.

[0035] See Figures 1-7 In the above embodiments, the frame 1, blocking frame 5, pusher 8, support leg 10, operating frame 12, push frame 14, and counterweight frame 16 are all assembled from Xingqiantian lean pipes and Xingqiantian lean pipe accessories. The flow strip 2, casters 3, limit block 4, rotating sleeve 6, guide sleeve 7, rotating joint 9, tension spring 11, first pull rope 13, pulley 15, and second pull rope 17 are all Xingqiantian lean pipe accessories or assembled from multiple Xingqiantian lean pipe accessories. Standardized components not only facilitate procurement and avoid the phenomenon of increased costs due to the need for separate processing of non-standard parts, but also allow for the purchase of corresponding standard parts for replacement if a component is damaged, reducing maintenance costs. At the same time, workers can adjust the size of the aluminum alloy lean pipe in the frame 1 or replace it with different specifications of flow strip 2 according to the needs of the actual use scenario, thereby changing the height of flow strip 2 and adapting it to material boxes of different sizes, thus meeting the usage needs of different manufacturers' production lines.

[0036] The implementation principle of this utility model is as follows: First, the staff needs to move the turnover cart to the process position where the goods are to be loaded, such as the shelf or warehouse shelf of the previous process. During the process, the casters 3 at the bottom of the cart frame 1 are used to move the equipment flexibly. When the turnover cart reaches the designated position, the staff releases the grip on the push handle 8. At this time, the tension spring 11 loses the external force constraint and begins to contract. The contraction force of the tension spring 11 drives the support foot 10 to slide down along the guide sleeve 7 until the support foot 10 is in contact with the ground, thereby realizing the automatic braking limit of the turnover cart. At the same time, the push handle 8 returns to the horizontal state under the linkage of the tension spring 11 and the support foot 10, without the need for the staff to walk around the cart frame 1 and manually operate the caster 3 to brake. Next, the loading process begins. The worker first rotates the blocking frame 5 upwards. When the blocking frame 5 rotates to abut against the limiting block 4, the limiting block 4 limits the maximum rotation angle of the blocking frame 5, preventing excessive rotation and keeping the blocking frame 5 tilted upwards to prevent it from falling back due to gravity. After rotating upwards, the blocking frame 5 no longer obstructs the material box from entering the vehicle frame 1. Subsequently, the worker pushes the material box containing the material to the top of the flow rails 2. Multiple flow rails 2 distributed along a U-shaped path collectively support the bottom and sides of the material box. The flow strip 2 provides support, and its roller structure reduces the contact friction between the material box and the frame 1, allowing the material box to move horizontally into the frame 1 more smoothly. After the material box is fully inside the frame 1, the staff rotates the blocking frame 5 back to its original position. Because the blocking frame 5 has a C-shaped cross section, it can limit the front and rear directions of the material box after it is reset, while the frame 1 itself limits the left and right directions of the material box. Together with the support of the bottom of the material box by the flow strip 2, the probability of the material box shaking or falling off the frame 1 during subsequent transportation is reduced. When materials need to be transferred, the worker rotates the pusher 8 downwards. The pusher 8 uses the rotating sleeves 6 on both sides of the top of the frame 1 as its rotational support base and begins to rotate downwards around the rotating sleeves 6. Since the bottom of the pusher 8 is connected to the support leg 10 through the rotating joint 9, and the support leg 10 is slidably connected to the guide sleeve 7 on the lower back of the frame 1, when the pusher 8 rotates, it will drive the support leg 10 to slide upwards along the guide sleeve 7 through the rotating joint 9. During this process, the rotating joint 9 can not only rotate itself, but also slide at the bottom of the pusher 8, thereby compensating for the trajectory conflict between the circular motion of the pusher 8 and the linear motion of the support leg 10, reducing the occurrence of dead points in the motion, and ensuring the stability of the support leg 10. The support foot 10 can smoothly move upward and detach from the ground, thereby releasing the brake of the turnover cart. The upward movement of the support foot 10 will cause the tension spring 11 to stretch and store force. The reason why the rotating joint 9 slides at the bottom of the pusher 8 is that the fastening bolt used to lock the rotating joint 9 and the pusher 8 is not fully tightened, which limits the rotating joint 9 and the pusher 8. Double nuts are used to prevent loosening. Therefore, the rotating joint 9 can slide without causing the bolt to fall off or the rotating joint 9 to separate from the pusher 8. After that, the staff can push the turnover cart through the pusher 8 and use the casters 3 to transfer the materials to the next process or the next workshop. There is no need to manually release the brake limit throughout the process, which further simplifies the operation process. When the trolley reaches the unloading position, i.e., the outer surface of the frame 1 is in contact with the shelf, the worker stops holding the push handle 8, the tension spring 11 retracts, causing the support foot 10 to move down to contact the ground, and the brake limit is restored. The push handle 8 simultaneously returns to a horizontal position, preparing for unloading. When entering the unloading stage, the worker drives the operating frame 12 down by hand or foot. During the descent of the operating frame 12, a pulley 15 on its outer surface presses down the first pull rope 13. The first pull rope 13 changes force under the action of part of the pulley 15. The direction of force transmission is changed, which in turn pulls the pusher 14 in the middle of the frame 1 forward. When the pusher 14 moves forward, it pushes the material box in the frame 1, causing the material box to move along the top of the flow bar 2 towards the warehouse shelf or equipment shelf. This eliminates the need for staff to walk to the side of the frame 1 to manually move the material box, reducing physical exertion during unloading. At the same time, the pusher 14 pulls the second pull rope 17 connected to it during its forward movement. The second pull rope 17 changes the direction of force transmission through another part of the pulley 15, causing the counterweight frame 16 to rise and store potential energy. After unloading is completed, the staff stops applying force to the operating frame 12. At this time, the counterweight frame 16 begins to move down under its own weight. When the counterweight frame 16 moves down, it pulls the push frame 14 in the opposite direction through the second pull rope 17, so that the push frame 14 moves backward along the frame 1 and resets, preparing for the next unloading. During the reset process, the push frame 14 will push the pulley 15 on the outer surface of the operating frame 12 upward through the first pull rope 13, so that the operating frame 12 moves upward along the frame 1 and resets. It should be noted that, except for the safety hooks at both ends of the first pull rope 13 and the second pull rope 17 (the safety hooks facilitate quick disassembly and replacement of the first pull rope 13 or the second pull rope 17 due to fatigue, overstretching, or breakage), the entire vehicle is assembled from Xingqiantian lean pipes and lean pipe accessories. For example, the frame 1 is composed of aluminum alloy lean pipes and third-generation lean pipe accessories such as external T-joints and 90° external elbow joints. The operating frame 12 and the guide frame are composed of aluminum alloy lean pipes and accessories such as external T-joints and linear rolling components. The counterweight frame 16 is also equipped with a counterweight bar. Furthermore, the limit block 4 consists of a round-headed hook, a rotating sleeve 6, and a guide sleeve 7. The components include a thickened linear rotating sleeve assembly, a 180° external rotating joint for the rotating joint 9, and a functional auxiliary component with a U-groove metal pulley kit for the pulley 15. Standardized components not only facilitate procurement and avoid the increased cost caused by the need for separate processing of non-standard parts, but also allow for the purchase of corresponding standard parts for replacement if a component is damaged, reducing maintenance costs. In addition, staff can adjust the size of the aluminum alloy lean tube in the frame 1 or replace it with different specifications of flow strip 2 according to the needs of the actual use scenario, thereby changing the height of flow strip 2 and adapting it to material boxes of different sizes, thus meeting the usage needs of different manufacturers' production lines.
