TECHNICAL FIELD

[0001] The utility model relates to material transportation auxiliary tool technical field, specifically, it is a material transport vehicle. BACKGROUND

[0002] In hardware processing, material transport vehicle refers to the tool that is used for carrying, loading and transporting hardware materials (such as steel products, tools, fasteners, etc.), and the material transport vehicle is very important in the material exchange of various processes.

[0003] At present, in the prior art, the material transport vehicle generally adopts a frame and a lifting structure arranged on the frame, and the material is manually carried to the platform with a certain conveying belt structure that can be lifted, then the trolley is pushed to the designated place, and then the material is unloaded by using the conveying belt or manual carrying mode, this material transportation mode reduces the efficiency because of manual carrying, and the frequent bending to carry the material also increases the working strength, and when carrying, this kind of material transport vehicle often has less protection and limitation to the material, when collision or overturning occurs, safety accidents are easy to occur, and after carrying is completed, only small force is needed to push due to the wheel slip structure of the material transport vehicle, and safety accidents are also easy to occur. SUMMARY

[0004] The utility model discloses a material transport vehicle, which aims to solve the technical problems of low carrying efficiency, high working strength of operators and low transportation safety factor in the prior art.

[0005] To solve the above technical problems, the utility model provides a material transport vehicle, which comprises a box body, a conveying mechanism, a lifting mechanism and a moving mechanism, the conveying mechanism is located at the inner bottom of the box body, the lifting mechanism is located at one side of the conveying mechanism, and the moving mechanism comprises a plurality of moving wheels arranged around the conveying mechanism.

[0006] In the above scheme, compared with a simple frame or platform, the box body is relatively closed, so that the materials stored inside are not disturbed during carrying, especially in areas with large environmental changes such as open-air passages, in addition, when the material transport vehicle is impacted by external force and overturned, the materials inside will not harm the surrounding personnel, effectively improving the protection ability and limitation of the materials, and further improving the safety factor of the transport vehicle.

[0007] The conveying mechanism is located at the bottom of the box body, the telescopic driving member and the moving wheel set are used for supporting and lifting the box body, when the moving wheel set moves relative to the box body to lower or lift the box body, the bottom of the box body is close to or away from the ground, and finally the box body abuts against the ground when the box body is close to the ground, so that the whole material transport vehicle is kept in a stationary state, the material transport vehicle is prevented from moving at will due to low friction of the moving wheel set, and the safety factor is improved, at this time, due to the contact between the bottom of the box body and the ground, the height difference between the material and the bottom of the box body is reduced, so that the push-pull assembly in the conveying mechanism can more smoothly pull the material located outside the box body into the box body, and therefore the moving mechanism is also beneficial to guarantee the operation efficiency and success rate of the conveying mechanism.

[0008] The conveying mechanism can pull or push the material into or out of the box body by using the push-pull assembly and the conveying driving member, so that the operation without manual carrying is realized, the strength and difficulty of transporting the material are reduced, and the efficiency of material transportation is improved.

[0009] Preferably, the push-pull assembly comprises a sliding block slidingly clamped on the box body, limit portions are arranged at both ends of the sliding block, and elastic limit members are arranged on the limit portions, one end of the elastic limit member is rotationally connected with the sliding block, and the two elastic limit members are relatively rotatable.

[0010] In the above scheme, the sliding block slidingly clamped on the box body means that the structure between the box body and the sliding block defines a moving direction for the sliding block, so that the sliding block can stably and accurately reach both sides of the material, and the accuracy and stability of the conveying mechanism when automatically storing and moving out the material are improved; the two elastic limit members are responsible for abutting against the material as a medium for transmitting the pulling force when the material is pulled into the box body, and for abutting against the material as a medium for transmitting the pushing force when the material is pushed out of the box body, and the relative rotation with respect to the fixed limit block means that the elastic limit member can be retracted by extrusion without the need for a driving device, thereby effectively improving the design flexibility of the push-pull assembly and saving production and processing costs, and when the elastic limit member is damaged by strong force, the sliding block does not need to be replaced, which is beneficial to subsequent maintenance; the limit portion limits the rotation position of the elastic limit member and bears the reaction force of the material on the elastic limit member when the material is pushed or pulled.

[0011] Preferably, the conveying mechanism further comprises a conveying guide assembly, the conveying guide assembly comprises a conveying guide rail arranged on the box body, and a moving seat slidingly clamped on the conveying guide rail, and the sliding block is connected with the moving seat.

[0012] In the above scheme, the conveying guide assembly avoids direct contact between the sliding block and the box, which can prevent the need to replace the entire box or sliding block when wear occurs at the sliding contact part between the sliding block or the box, thereby prolonging the service life of the box and the push-pull assembly and saving production and processing costs; the conveying guide rail and the moving seat can provide more accurate and stable linear motion and better load capacity, ensuring smooth sliding of the sliding block during movement, enabling the push-pull assembly to accurately and effectively push and pull the material, and being able to withstand heavier types of material.

[0013] Preferably, the conveying mechanism further comprises a conveying transmission assembly, the conveying transmission assembly comprising an output gear provided at the output end of the conveying drive member, a rack provided on the sliding block, and a double gear connected to the rack in meshing connection, the output gear and the double gear being connected through a synchronous belt.

[0014] In the above scheme, the synchronous belt is used to connect the output gear and the double gear, which facilitates smooth power transmission, reduces noise and wear caused by direct contact of metal parts, and can also absorb vibrations to some extent, making the entire system run more stably and reducing the impact load on mechanical equipment; the synchronous belt generally does not need to be lubricated, which can reduce the daily maintenance requirements and is relatively simple to replace or adjust; in addition, if an overload occurs, the synchronous belt will slip instead of breaking, which helps to protect the safety of the entire system and avoids damage caused by sudden stop; the rack and the double gear ensure smooth operation of the linear motion of the push-pull assembly, which is conducive to improving the stability of the transmission system.

[0015] Preferably, one side of the box is provided with an inlet and outlet, and a front cover plate is provided at the inlet and outlet, the front cover plate being rotatably connected to the box and having a slope body structure, and the conveying drive member drives the push-pull assembly to move towards or away from the front cover plate along the direction of the inlet and outlet.

[0016] In the above scheme, the inlet and outlet are used for the material to enter or exit the inside of the box and provide a guide for the moving direction of the push-pull assembly; when the bottom of the box contacts the ground, the front cover plate also rotates to fit the ground, and the slope body structure of the front cover plate facilitates smoother travel of the material between the ground and the inside of the box and reduces the force required for the push-pull assembly to push and pull the material.

[0017] Preferably, a plurality of rotating shafts are provided at the side opposite to the box and are rotatably connected to the front cover plate.

[0018] In the above scheme, the rotating shaft is used to reduce the resistance of the material sliding on the front cover plate, and further reduce the force required for the push-pull assembly to push and pull the material, which is beneficial to provide the smoothness and stability of the push-pull assembly when pushing and pulling the material. In addition, multiple rotating shafts are provided to cover the entire front cover plate as much as possible, thereby prolonging the time of the above beneficial effects.

[0019] Preferably, the lifting mechanism comprises a bearing platform slidingly clamped in the box body, and a lifting drive member driving the bearing platform to reciprocate in the vertical direction, and the bearing platform is located between the two push-pull assemblies.

[0020] In the above scheme, after the push-pull assembly pulls the material into the box body, the material will slide into the bearing platform located between the two push-pull assemblies, and then be lifted by the bearing platform. Therefore, the bearing platform arranged between the two push-pull assemblies is beneficial to improve the working efficiency of the material transport vehicle and save design space. The bearing platform slidingly clamped in the box body limits the direction of lifting the material by the bearing platform and provides a smoother and more stable lifting process, which is beneficial to improve the stability and smoothness of the lifting mechanism. After lifting the material, the bearing platform limits the displacement of the material together with the box body, which is beneficial to prevent the material from moving randomly in the box body and improve its safety factor. In addition, when there are multiple bearing platforms, more materials can be accommodated.

[0021] Preferably, a lifting guide assembly is further arranged between the bearing platform and the box body, the lifting guide assembly comprises a lifting guide rail and a lifting seat slidingly clamped on the lifting guide rail, and the bearing platform is connected with the lifting seat.

[0022] In the above scheme, the effect of the conveying guide assembly is basically the same, which can avoid direct contact between the bearing platform and the box body, and prevent the need to replace the entire box body or bearing platform when wear occurs at the sliding clamping part between the bearing platform or the box body. This is beneficial to prolong the service life of the box body and the lifting mechanism and save production and processing costs. The lifting guide rail and the lifting seat can provide more accurate and stable linear motion and better load capacity, ensuring smoother sliding and more stable guidance of the bearing platform during lifting of the material, and being able to withstand heavier and more materials.

[0023] Preferably, the lifting mechanism further comprises a lifting transmission assembly, the lifting transmission assembly comprises a driving gear arranged at the output end of the lifting drive member, and two fixed shafts arranged at intervals on the box body, two load gears are rotatably arranged on the two fixed shafts, and a driven gear is fixedly connected to one of the fixed shafts. The driving gear and the driven gear are connected through a first transmission chain, and the two load gears are connected through a second transmission chain, and the bearing platform is fixedly connected with the second transmission chain.

[0024] In the above scheme, the combination of the gear and the transmission chain can effectively convert the rotating force provided by the lifting drive into linear motion to lift the carrying platform, which is beneficial to improve the energy conversion efficiency, complete a more complex transmission path with a smaller space occupation, improve the space utilization of the material transport vehicle, reduce the floor area to facilitate transportation, and withstand long-term work load, which is beneficial to prolong the service life of the entire lifting mechanism. Two load gears can evenly distribute the load between the two fixed shafts, reducing the risk of single-point overload and helping to improve the stability and reliability of the entire system; maintenance and replacement are relatively simple, and the gear ratio can be adjusted according to actual needs to meet different speed and torque requirements, improving the applicability of different types of materials.

[0025] Preferably, the top of the box is provided with a top cover plate, which is rotatably connected with the box.

[0026] In the above scheme, the top of the box is provided with an opening, and a top cover plate that can be rotatably opened. When it is necessary to transport materials to an irregular position, such as a high place, an obstacle blocking place, or a conveying mechanism failure, the top cover plate can be opened, and the materials can be manually taken out. Since it is in a lifted state, it is not necessary to bend down to lift the materials. While providing diversified transportation methods, the working intensity of the operator can be reduced.

[0027] Compared with the prior art, the utility model has the advantages that:

[0028] Compared with a simple frame or platform, the relatively closed box structure can protect the materials stored inside from external interference during transportation, especially in areas with large environmental changes such as open channels. In addition, when the material transport vehicle is impacted by external forces and overturned, the materials inside will not harm the surrounding personnel, effectively improving the protection ability and limiting effect of the materials, and further improving the safety factor of the utility model. Compared with manual material handling, the use of a conveying mechanism that can automatically pull or push materials into or out of the box, and a lifting mechanism that can lift materials inside the box, can effectively reduce the working intensity of the operator and improve the efficiency of material transportation. The moving mechanism can lift the box and change the center of gravity of the transport vehicle, so that the transport vehicle can retract the moving wheel set and lower the box to the ground to increase the friction when it needs to remain stationary, and extend the moving wheel set and raise the box to reduce the friction when it needs to push the transport vehicle. This is beneficial to ensure the normal operation of automatic material pushing and pulling, prevent the transport vehicle from changing its motion state at will due to external forces, and further improve its safety factor.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the related drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein.

[0036] In the description of the utility model, it is understood that the terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0037] In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0038] In the embodiment, referring to Figures 1-4 The utility model provides a material transport vehicle, it includes box 100, be equipped with conveying mechanism 200, lifting mechanism 300 and mobile mechanism 400 on box 100, conveying mechanism 200 is located at the bottom of box 100, lifting mechanism 300 is located at one side of conveying mechanism 200, mobile mechanism 400 is multiple and surrounds conveying mechanism 200 and sets up, conveying mechanism 200 includes two push -and -pull assemblies 210 that are symmetrically arranged in box 100, and conveying drive piece 240 for driving push -and -pull assembly 210 to go in and out of box 100, mobile mechanism 400 includes telescopic drive piece 420 for supporting box 100 and mobile wheel group 410 connected with telescopic drive piece.

[0039] It can be understood that compared with the simple frame or platform, the box 100 is relatively closed and the overall height is relatively low, and the side of the box 100 has an inclined angle that shrinks towards the top, which means that the box 100 is less likely to overturn, can better protect the internal materials and surrounding personnel, and is isolated from the outside during transportation.

[0040] Conveying mechanism 200 and telescopic drive piece 420 are located at the bottom of box 100, mobile wheel group 410 is connected with the output end of telescopic drive piece 420, when telescopic drive piece 420 drives mobile wheel group 410 to move relative to box 100, box 100 can be jacked up or lowered, and the bottom of box 100 can be close to or away from the ground, when box 100 abuts against the ground, the entire material transport vehicle can be kept in a stationary state, at this time, due to the contact between the bottom of box 100 and the ground, the height difference between the materials and the bottom of box 100 is reduced, so that the push-pull assembly 210 in the conveying mechanism 200 can more smoothly pull the materials located outside the box 100 into the box 100.

[0041] Two push-pull assemblies 210 are arranged on one side of the box 100 to push and pull the materials in and out of the box 100, and therefore, at least one opening is needed on the side of the box 100 for the materials to enter and exit.

[0042] In addition, in some embodiments, a friction pad or other components that increase the friction between the box 100 and the ground can be arranged at the bottom of the box 100 to ensure that the box 100 can withstand greater force without displacement when the box 100 is in abutment with the ground; the types of driving components include but are not limited to linear motor driving, hydraulic driving device, and motor, which are subject to the above-mentioned functions.

[0043] In addition, in some embodiments, the moving mechanism 400 further includes a handle 120 and a control panel 130, the handle 120 is used to assist in pushing the material transport vehicle, and the control panel 130 is electrically connected with the conveying mechanism 200, the lifting mechanism 300, and the moving mechanism 400.

[0044] In the present embodiment, please refer to Figure 2 and Figure 3 The push-pull assembly 210 includes a sliding block 211 slidingly arranged on the box 100, both ends of the sliding block 211 are provided with a limiting portion 212 and an elastic limiting component 213 arranged on the limiting portion 212, one end of the elastic limiting component 213 is rotatably connected with the sliding block 211, and the two elastic limiting components 213 can be relatively rotated.

[0045] It can be understood that the sliding block 211 slidingly arranged on the box 100 means that the structure between the box 100 and the sliding block 211 defines a guide direction, which can make the sliding block 211 stably and accurately reach both sides of the materials, and such structure is generally a sliding groove and a sliding convex portion matched with the sliding groove;

[0046] The two elastic limiting components 213 are responsible for abutting with the materials as a medium for transmitting pulling force when pulling the materials into the inside of the box 100, and are responsible for abutting with the materials as a medium for transmitting pushing force when pushing the materials out of the inside of the box 100, and when there is no driving device to drive the elastic limiting component 213 to rotate, the relatively rotatable means that the elastic limiting component 213 can be retracted by extrusion without the need for a driving device, so that the materials can enter between the two elastic limiting components 213, and then the elastic limiting component 213 is stretched to push and pull the materials;

[0047] Generally, the limiting portion 212 limits when the elastic limiting component 213 is perpendicular to the sliding block 211, which can balance the space occupation and the force transmission efficiency, and the limiting portion 212 can be a groove arranged on the sliding block 211 or a protrusion on the sliding block 211.

[0048] In addition, in some embodiments, the rotation of the elastic limiting member 213 can also be controlled by the driving device, so as to improve the flexibility of the setting position and the use time.

[0049] Specifically, the conveying mechanism 200 further comprises a conveying guide assembly 220, which comprises a conveying guide rail 221 arranged on the box body 100 and a moving seat 222 slidably arranged on the conveying guide rail 221, and the sliding block 211 is connected with the moving seat 222.

[0050] It can be understood that the conveying guide rail 221 is arranged inside the box body 100, and the moving seat 222 is arranged at one end of the sliding block 211, which means that when the moving seat 222 moves from one end to the other end of the conveying guide rail 221, the sliding block 211 can be maximally extended outside the box body 100.

[0051] In addition, in some embodiments, in order to prolong the pushing and pulling distance of the material, the conveying guide assembly 220 can also be extended outside the box body 100, at this time, in order to facilitate the storage of the conveying guide rail 221, the conveying guide rail 221 can be arranged as a folding guide rail.

[0052] More specifically, the conveying mechanism 200 further comprises a conveying transmission assembly 230, which comprises an output gear 231 arranged at the output end of the conveying driving member 240, a rack 232 arranged on the sliding block 211, and a double gear 233 engaged with the rack 232, and the output gear 231 and the double gear 233 are connected through a conveying synchronous belt 234.

[0053] It can be understood that the box body 100 is internally provided with a space for accommodating the conveying transmission assembly 230, so that the conveying transmission assembly 230 is not exposed.

[0054] In addition, in some embodiments, a clutch assembly can also be arranged in the transmission chain of the conveying transmission assembly 230, so as to improve the stability and reliability of the transmission process.

[0055] In this embodiment, please refer to Figure 1 and Figure 2 It can be understood that the box body 100 is internally provided with a space for accommodating the conveying transmission assembly 230, so that the conveying transmission assembly 230 is not exposed.

[0056] It can be understood that the inlet and outlet 110 is used for feeding and discharging materials into and out of the box body 100, and provides a guide for the moving direction of the push-pull assembly 210; one side of the front cover plate 140 is rotationally connected with the box body 100, and the inclined surface structure of the front cover plate 140 is specifically that when it is rotated and opened to one side and abuts against the ground, an inclined surface can be formed from the inlet and outlet 110 to the ground, so that the materials can smoothly enter the box body 100; the moving direction of the push-pull assembly 210 is also the same as the direction of the inlet and outlet 110.

[0057] In addition, in some embodiments, the inlet and outlet 110 can also be an inclined surface structure.

[0058] Specifically, a plurality of rotating shafts 141 are arranged on the side of the front cover plate 140 opposite to the box body 100, and the plurality of rotating shafts 141 are rotationally connected with the front cover plate 140.

[0059] It can be understood that, since the front cover plate 140 is an inclined surface structure, the size of the plurality of rotating shafts 141 should change with the thickness of the inclined surface, but the distance protruding from the front cover plate 140 should remain the same to avoid hindering the process of material transportation.

[0060] In addition, in some embodiments, the plurality of rotating shafts 141 can also be replaced by universal balls.

[0061] In the embodiment, please refer to Figure 1 , Figure 2 and Figure 4 , the lifting mechanism 300 includes a carrying platform 310 slidingly clamped in the box body 100 and a lifting drive 320 driving the carrying platform 310 to reciprocate in the vertical direction, and the carrying platform 310 is located between the two push-pull assemblies 210.

[0062] It can be understood that the initial height of the materials carried on the carrying platform 310 is lower than the height of the materials entering the box body 100, which means that a containing groove for containing the carrying platform 310 can also be arranged at the bottom of the box body 100; the carrying platform 310 is an "L" type structure, and the opposite side is used for carrying materials.

[0063] In addition, in some embodiments, a plurality of carrying platforms 310 can also be arranged for multiple times of containing materials; the rotating shafts 141 or universal balls can also be arranged on the carrying platform 310 as the front cover plate 140.

[0064] Specifically, the carrying platform 310 and the box body 100 are further provided with a lifting guide assembly 330, the lifting guide assembly 330 includes a lifting guide rail 331 and a lifting seat 332 slidingly clamped in the lifting guide rail 331, and the carrying platform 310 is connected with the lifting seat 332.

[0065] Understandably, the lifting guide rail 331 is set vertically on the inner wall of the box 100, and the carrying platform 310 moves along the lifting guide rail 331 via the moving seat 222 to lift materials. The lifting guide rail 331 and the lifting seat 332 should be selected with a size similar to that of the carrying platform 310 to provide higher load and a more stable lifting process.

[0066] Specifically, the lifting mechanism 300 also includes a lifting transmission assembly 340, which includes a drive gear 341 located at the output end of the lifting drive component 320 and two fixed shafts 342 spaced apart on the housing 100. Load gears 343 are rotatably mounted on both fixed shafts 342, and a driven gear 344 is fixedly connected to one of the fixed shafts 342. The drive gear 341 and the driven gear 344 are connected by a first transmission chain 345, and the two load gears 343 are connected by a second transmission chain 346. The bearing platform 310 is fixedly connected to the second transmission chain 346.

[0067] Understandably, due to the linkage between the moving mechanism 400 and the conveying mechanism 200, it is best to avoid adding components to the carrying platform 310 and the bottom of the box 100. Therefore, using a transmission chain is more ideal. Since the lifting transmission assembly 340 is a transmission chain connection, it has low requirements for the environment. Therefore, it can be set inside or outside the box 100. The two fixed shafts 342 are respectively set at the top and bottom of the box 100 to correspond to the height of the lifting material.

[0068] In addition, in some embodiments, the load gear 343 can be set to multiple, and correspondingly, the second transmission chain 346 can also be multiple; when the bearing platform 310 has multiple, or when it is necessary to increase the load capacity of the bearing platform 310, multiple sets of lifting transmission components 340 can be set, and the multiple sets of lifting transmission components 340 are spaced apart.

[0069] Furthermore, in some embodiments, the lifting transmission assembly 340 may also be configured as a rack and pinion drive connection.

[0070] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the top of the box 100 is provided with a top cover plate 150, which is rotatably connected to the box 100.

[0071] Understandably, the top of the box 100 has an opening, and the top cover 150 covers the opening. One end of the top cover 150 is rotatably connected to the box 100 via a hinge 151, and the top cover 150 can be opened to one side. When it is necessary to move the material to an unconventional location, such as a high place, an obstacle blocking the way, or when the conveyor mechanism 200 malfunctions, the top cover 150 can be opened and the material can be manually removed.

[0072] In addition, in some embodiments, the top cover plate 150 can also be arranged to be relatively openable, and is respectively rotationally connected with the box body 100.

[0073] The specific application process of the utility model is as follows:

[0074] Material storage: the material transport vehicle is moved to the front of the material, the telescopic driving part 420 shrinks the moving wheel set 410 to the box body 100, so that the box body 100 is lowered to abut against the ground, and the relative position of the whole material transport vehicle is kept unchanged, the front cover plate 140 is rotationally opened to one side to abut against the ground, forming an inclined plane from the ground to the inlet and outlet 110, the two side sliders 211 are extended outside the box body 100 from the inlet and outlet 110 through the conveying guide assembly 220, and pass through the two sides of the material, the two pairs of elastic limit parts 213 on the two push-pull assemblies 210 are all relatively rotated to retract the sliders 211, and are bounced back after the sliders 211 completely cover the two sides of the material, the two side sliders 211 are retracted inside the box body 100 through the conveying guide assembly 220, the elastic limit parts 213 abut against the material and pull the material to move to the inside of the box body 100, the material passes through the plurality of rotating shafts 141 along the inclined plane of the front cover plate 140, and is finally placed on the bearing platform 310, the front cover plate 140 is closed, and the material is lifted through the lifting guide assembly 330, the telescopic driving part 420 extends the moving wheel set 410 outside the box body 100 to lift the whole material transport vehicle, and then the material transport vehicle is pushed to the designated position.

[0075] Material removal: mode one is to reverse the steps of material storage, at this time, the elastic limit part on the other side of the slider pushes the material; mode two is to open the top cover plate 150 and manually take out the material.
