Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a material handling anti-tipping fixing frame. Background Technology

[0002] Material handling vehicles are specialized vehicles or equipment used for handling, transferring and transporting various materials. They are widely used in industries such as industry, agriculture, logistics, and construction. Depending on different application scenarios and functional requirements, material handling vehicles can be divided into various types, including automated transport vehicles, bulk material transport vehicles, hand-pushed hopper vehicles, and semi-trailers.

[0003] When transporting materials, sometimes a large amount of materials are piled up on the transport equipment in order to complete the task quickly, resulting in extremely high material height. Such materials are very prone to tipping over during transport. Some materials may tip over during transport simply because they are already tall. This not only causes damage to the materials, but also easily injures people nearby.

[0004] CN216072182U discloses a material handling device, including a handling box. A bottom seat is fixedly connected to the bottom of the handling box. A connecting bar is rotatably connected to the inside of the bottom seat via a rotating shaft. A rotating bar is rotatably connected to one end of the connecting bar via a rotating shaft. A movable seat is rotatably connected to one end of the rotating bar via a rotating shaft. A fixed threaded rod is rotatably connected to the inside of the movable seat via a thread. A handling vehicle body is rotatably connected to one end of the fixed threaded rod via a bearing.

[0005] However, the following problems were found in the implementation of the relevant technology: due to the lack of a fixed structure, the utility model is prone to material tipping when transporting materials that are too high, and in severe cases, it may even injure workers when the materials tip over. Utility Model Content

[0006] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a material handling anti-tipping fixing frame, which has the advantage of preventing material tipping and solves the problem that material tipping is easy to occur when transporting materials at a high height. Through its internal structure, it ensures the safety of materials during transportation and the surrounding staff, and avoids material damage and personnel injury.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a material handling anti-tipping fixing frame, including a fixing frame body, the fixing frame body including a base plate and side plates vertically arranged on both sides of the base plate, forming a material conveying channel between the base plate and the side plates; including clamping plates and adjusting components, each side plate is provided with a clamping plate on its inner side, and the adjusting components drive the clamping plates on both sides to move towards or away from each other to adjust the width of the material conveying channel.

[0008] In the above solution, to address the problem that the top of the material is prone to tipping over during the original material handling process, the top is designed to be positioned and fixed from top to bottom and from both sides inward. This can effectively prevent the material from tilting and avoid the tipping problem that is prone to occur when transporting materials at a high height, thus effectively ensuring the safety of transportation.

[0009] Furthermore, the opposing movement of the clamping plates is limited by the sliding grooves. The base plate has several sets of sliding grooves corresponding to the opposing movement direction of the two clamping plates. Each set of sliding grooves includes two sliding grooves. The two sliding grooves are symmetrically arranged on both sides of the line of symmetry with the line connecting the midpoint of the width of the base plate as the line of symmetry. The upper end of the clamping plate is fixed with a sliding block that slides in cooperation with the sliding groove. The adjustment component drives the sliding block to slide in the sliding groove.

[0010] Furthermore, the power for the opposing movement of the clamping plates is provided by an adjustment assembly, which includes several bidirectional lead screws, with one bidirectional lead screw corresponding to each set of slide grooves. The two threads of the bidirectional lead screw are respectively set to correspond to the two slide grooves of their respective sets, and the sliding blocks in the slide grooves are rotatably engaged with the corresponding threads. Each slide groove has a first fixing block fixed at the end near the long side of the base plate and a second fixing block fixed at the end near the line of symmetry. The bidirectional lead screw is rotatably connected to the first and second fixing blocks of its corresponding set of slide grooves, and the bidirectional lead screw is axially positioned with the first and second fixing blocks. The sliding blocks are engaged with the bidirectional lead screw corresponding to the slide groove. Through the movement of the bidirectional lead screw, the threads at both ends are driven to rotate, thereby realizing the rotation of the bidirectional lead screw and driving the sliding blocks engaged with the threads to perform synchronous movements of moving towards or away from each other.

[0011] Furthermore, the adjustment assembly includes a motor, several synchronous pulleys, and a synchronous belt. Each bidirectional lead screw is fixed with a synchronous pulley, and the synchronous pulleys between adjacent bidirectional lead screws are synchronously driven by the synchronous belt. The output end of the motor is connected to any one of the bidirectional lead screws and drives it to rotate. By using synchronous pulleys and synchronous belts, the same motor can be used to achieve synchronous movement of multiple bidirectional lead screws, effectively ensuring the synchronicity of the clamps' movements in opposite directions or away from each other.

[0012] Preferably, protective pads are fixed on the opposite surfaces of the two side plates, which can effectively protect the materials.

[0013] Furthermore, the lower end face of the clamping plate is concave and has several vertical grooves, within which sliding members are slidably connected. The sliding members provide a further means of limiting movement in the vertical direction.

[0014] Furthermore, the sliding member and the vertical groove can be positioned by magnetic attraction. A metal shaft is rotatably connected to the sliding member, and a magnet is fixed to the side of the lower end of the clamping plate corresponding to the vertical groove. When the sliding member slides to the lower end of the vertical groove, the magnet attracts the metal shaft to position the sliding member and the vertical groove.

[0015] Furthermore, the upper end of the sliding member is symmetrically hinged with fixing strips on both sides, and the lower end of the sliding member is symmetrically hinged with protective strips on both sides. Both the fixing strips and the protective strips are provided with several fixing holes. The fixing strips and protective strips on the same side of the same sliding member are fixed by screws that fit in the positioning holes.

[0016] Preferably, to prevent the sliding member from rubbing against the bottom of the vertical groove, a rubber pad is fixed to the bottom of the vertical groove, and the sliding member abuts against the rubber pad when it moves to the bottommost position.

[0017] The beneficial effects of this utility model are as follows: This utility model uses a motor to drive a bidirectional lead screw, which in turn drives a synchronous pulley. The synchronous pulley drives another synchronous pulley via a synchronous belt, and the other synchronous pulley drives another bidirectional lead screw. Multiple bidirectional lead screws drive two clamping plates to move. While the two clamping plates are moving, they fix the two sides of the material, thereby preventing the material from tipping over. This solves the problem of material tipping over when transporting materials at a high height. The internal structure ensures the safety of the material during transportation and the surrounding personnel, avoiding material damage and personnel injury.

[0018] Meanwhile, this utility model increases the area of ​​the sliding component by pulling it out from the inside of the vertical groove, and then rotating the protective strip and fixing strip out of the inside of the sliding component and fixing them with screws. This increases the interception area of ​​the material. Then, the position of the metal shaft is adjusted so that the metal shaft and the magnet attract each other to fix the sliding component, so that the sliding component can intercept the material. This increases the adaptability of the fixing frame, making it suitable for materials of various heights. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0026] like Figures 1 to 4 As shown, this utility model provides a material handling anti-tipping fixing frame, including a fixing frame body 1 and an adjustment assembly. The fixing frame body 1 includes a base plate and side plates perpendicular to both sides of the base plate. A material conveying channel is formed between the side plates and the base plate.

[0027] The base plate has three sets of sliding grooves, each set containing two grooves. The two grooves are symmetrically arranged on both sides of the line connecting the midpoints of the base plate's width. Each side plate has a clamping plate 305 that moves along the sliding groove on its inner side. Each clamping plate 305 has three sliding blocks 306 on its top. The sliding grooves and sliding blocks 306 correspond one-to-one and slide in engagement. The movement of the sliding blocks 306 relative to the sliding groove drives the clamping plates 305 on both sides to move towards or away from each other, thereby adjusting the width of the material conveying channel.

[0028] Specifically, the bottom end of the base plate is provided with a first fixing block 2 and a second fixing block 4 at both ends of each slide groove. The first fixing block 2 is located at the end of each slide groove near the long side of the base plate, and the second fixing block 4 is located at the end near the line of symmetry.

[0029] The adjustment assembly includes three bidirectional lead screws 302, three synchronous pulleys 303, two synchronous belts 304, and a set of motors 301. Each set of slides corresponds to one bidirectional lead screw 302. The bidirectional lead screw 302 is rotatably connected between the first fixed blocks 2 corresponding to the slides in the same set, and the middle part of the bidirectional lead screw 302 is rotatably connected to the middle part of the second fixed block 4. The bidirectional lead screw 302 can rotate relative to the first fixed block 2 and the second fixed block 4.

[0030] The two ends of the bidirectional lead screw 302 rotate in opposite directions. The two clamping plates 305 are respectively set on the front and rear inner walls of the fixed frame body 1. The two ends of the bidirectional lead screw 302 will drive the sliding blocks 306 on both sides to move closer to each other, thereby driving the two clamping plates 305 to move closer to each other. Protective pads 307 are fixedly installed on the opposite side of the two clamping plates 305. The protective pads 307 can protect some easily damaged materials and also prevent the materials from being damaged due to excessive clamping force.

[0031] In this embodiment, the motor 301 is mounted on the rear end of the fixed frame body 1 via a motor mount, and the output end of the motor 301 is coaxially connected to the rear end of one of the bidirectional lead screws 302. The output end of the motor 301 can drive the corresponding bidirectional lead screw 302 to rotate. The synchronous pulley 303 is sleeved on the outer side of the middle part of the bidirectional lead screw 302, and the outer sides of two adjacent synchronous pulleys 303 are connected by a synchronous belt 304. Through the cooperation of multiple sets of synchronous pulleys 303 and synchronous belts 304, multiple bidirectional lead screws 302 rotate synchronously. With the arrangement of synchronous pulleys 303 and synchronous belts 304, one set of motors 301 can drive three bidirectional lead screws 302 to move synchronously, thereby driving the sliding block 306 to move synchronously and smoothly driving the clamping plate 305 to slide.

[0032] like Figure 3 and Figure 4 The lower end face of the clamping plate 305 has a recessed groove with multiple vertical grooves 8. A sliding member 5 is slidably installed inside the groove 8. The sliding member 5 can slide inside the groove 8. Two protective strips 7 are symmetrically hinged to the upper outer side of the sliding member 5, and two fixing strips 9 are symmetrically hinged to the lower outer side of the sliding member 5. Multiple fixing holes are arranged side by side on the surfaces of the protective strips 7 and the fixing strips 9. Both the protective strips 7 and the fixing strips 9 can be rotated out from the inside of the sliding member 5. The corresponding protective strips 7 and fixing strips 9 can be fixed by screws that cooperate with the fixing holes, thereby increasing the area of ​​the corresponding sliding member 5 to increase the interception area of ​​the material. The interception area is adjustable.

[0033] A magnet 11 is fixedly installed inside the lower end face of the clamping plate 305, and the magnet 11 is positioned opposite to the side of the vertical groove 8. A metal shaft 10 is magnetically attracted to the outside of the magnet 11, and the metal shaft 10 is rotatably connected to the sliding member 5. After the sliding member 5 slides down to the end, the metal shaft 11 can be rotated open, and the magnet 11 and the metal shaft 10 are magnetically attracted and fixed, thereby fixing the extended sliding member 5 to the vertical groove 8. A rubber pad 6 is adhered to the bottom of the vertical groove 8. When the sliding member 5 moves to the bottommost position, it abuts against the rubber pad 6, which can prevent the sliding member 5 and the bottom of the vertical groove 8 from wearing each other.

[0034] Among them, motor 301 is prior art and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows:Figure 1 The direction shown in the diagram is the reference.

[0035] Working principle: When using the material handling anti-tipping fixing frame, the fixing frame body 1 can be installed on the top of the transport vehicle. Then, the motor 301 is turned on, and the motor 301 drives the corresponding bidirectional lead screw 302 to rotate. Through the cooperation of multiple sets of synchronous pulleys 303 and synchronous belts 304, multiple bidirectional lead screws 302 rotate synchronously. While rotating, the bidirectional lead screws 302 drive the clamping plate 305 to move through the threaded engagement of the sliding block 306. The two clamping plates 305 move closer to each other to fix the two sides of the material, thereby playing the role of anti-tipping. The protective pad 307 can protect the more fragile materials and prevent them from being squeezed, deformed or damaged. If the height is not enough, the sliding part 5 can be pulled out from the inside of the vertical groove 8, and then the protective strip 7 and fixing strip 9 can be turned out from the inside of the sliding part 5 and fixed with screws to increase the area of ​​the sliding part 5. Then, the metal shaft 10 and the magnet 11 are magnetically attracted to each other to fix the sliding part 5, which can accommodate materials with higher height.
