Description

A foldable box-shaped forklift and tipping device for engineering vehicles. Technical Field

[0001] This utility model relates to the field of forklift device technology, and more specifically, to a foldable box-type forklift and flipping device for engineering vehicles. Background Technology

[0002] Traditional forklifts typically refer to the fork arms and related components on a forklift used for handling and loading / unloading goods.

[0003] Traditional forklift devices have the following drawbacks:

[0004] 1. Lacks flip function;

[0005] Traditional forklifts can only carry the box horizontally and cannot achieve the flipping function. When there is a need to flip the box, an additional independent flipping mechanism is required, which makes the front structure of the vehicle bulky.

[0006] 2. The transport volume is too large;

[0007] When the distance between different work areas is far or the ground conditions are not suitable for direct driving of the forklift, it is necessary to transfer the forklift by other transport vehicles. The outline of the fork arms and accessories exceeds the body outline of the transport vehicle, resulting in the overall size of the transport vehicle exceeding the standard and restricting its road traffic capacity.

[0008] 3. Protective devices hinder storage;

[0009] Existing protective baffles for cases are mostly welded and fixed, which hinders folding and storage and cannot be adapted to cases of different sizes. Summary of the Invention

[0010] The present invention aims to provide a foldable box-type forklift and flipping device for engineering vehicles, in order to solve the problems of traditional forklift devices lacking flipping function, excessive transportation volume, and protective devices hindering storage.

[0011] This utility model is achieved using the following technical solution:

[0012] This utility model provides a foldable box-shaped forklift and tilting device for engineering vehicles, including a fixed device and a movable device. The fixed device is used to connect with the engineering vehicle, and the movable device is rotatably connected to the fixed device. A tilting drive mechanism is connected between the movable device and the fixed device.

[0013] The movable device is detachably connected to a fork and a protective baffle.

[0014] With the above structure, the forklift can lift the container, allowing it to be horizontally supported, while the protective baffle provides protection and stops. The tilting drive mechanism controls the rotation of the movable device relative to the fixed device, causing it to tilt. The forklift and the protective baffle rotate accordingly, and the container tilts onto the movable device, where it is supported. The forklift and the protective baffle then protect the container. This container lifting and tilting device integrates the lifting and tilting (typically 90°) of a container (such as a cargo box), eliminating the need for a separate tilting mechanism and preventing a bulky front-end structure on engineering vehicles.

[0015] Since the fork and the protective baffle are detachably connected to the movable device, they can be removed when not in operation, and can be stored away to reduce the overall size of the device, thereby reducing the overall size of the engineering vehicle. When the engineering vehicle is transferred by other transport vehicles, the outer contour of the box-type forklift and tilting device of this utility model can be prevented from exceeding the outline of the transport vehicle body, ensuring the road traffic capacity of the transport vehicle, improving the vehicle's flexibility and passability, and facilitating operation in confined spaces.

[0016] After the fork and the protective baffle are removed, their installation positions can be adjusted according to the size of the box to accommodate boxes of different sizes.

[0017] As a preferred technical solution:

[0018] The fixed device includes a fixed frame, and the movable device includes a movable frame, which is rotatably connected to the fixed frame.

[0019] As a preferred technical solution:

[0020] The movable frame can be rotatably connected to the fixed frame via a pin, but is not limited to.

[0021] As a preferred technical solution:

[0022] The tilting drive mechanism may be, but is not limited to, a hydraulic cylinder; other mechanisms capable of driving the movable frame to rotate may also be used.

[0023] As a preferred technical solution:

[0024] The bottom of the movable frame is rotatably connected to the front end of the fixed frame. The movable frame has a first position arranged vertically and a second position arranged horizontally after being flipped over.

[0025] As a preferred technical solution:

[0026] One end of the fork is connected to the movable frame, and the fork has a third position perpendicular to the movable frame in the working state and a fourth position parallel to the movable frame in the stored state.

[0027] As a preferred technical solution:

[0028] When the movable frame is arranged vertically, one end of the fork is connected to the bottom front end of the movable frame.

[0029] As a preferred technical solution:

[0030] The protective baffles are symmetrically connected to both sides of the movable frame, one end of each protective baffle is connected to the movable frame, and the protective baffles are perpendicular to the movable frame.

[0031] As a preferred technical solution:

[0032] When the movable frame is arranged vertically, the protective baffle has a fifth position in which it extends out of the front end of the movable frame in the working state and a sixth position in which it does not extend out of the front end of the movable frame in the stored state.

[0033] In the working state, one end of the protective baffle is connected to the movable frame, and the protective baffle extends beyond the front end of the movable frame. When lifted by forks, the protective baffle protects both sides of the container. When the movable frame flips, the container also flips, and the protective baffle continues to protect both sides of the container. In the storage state, the other end of the protective baffle is connected to the movable frame, and the protective baffle is retracted, no longer extending beyond the front end of the movable frame. This reduces the space occupied and the size of the entire device and the engineering vehicle.

[0034] As a preferred technical solution:

[0035] A semi-fixed baffle is detachably connected to the fixed frame, and the semi-fixed baffle is arranged vertically.

[0036] The semi-fixed baffle is used to protect and stop the other side of the overturned box. The fork, the protective baffle, and the semi-fixed baffle provide comprehensive protection around the overturned box, thus achieving stable fixation of the box.

[0037] As a preferred technical solution:

[0038] The semi-fixed baffle has multiple connection holes of different heights, and the fixing frame has connection holes for connecting the semi-fixed baffle. The semi-fixed baffle and the fixing frame are connected by installing connectors in the connection holes.

[0039] By aligning the different connecting holes on the semi-fixed baffle with the connecting holes on the fixed frame, and installing connectors (bolts) in the holes, different installation heights of the semi-fixed baffle can be achieved, and the protective height of the semi-fixed baffle can be adjusted.

[0040] As a preferred technical solution:

[0041] The fixing device is used to connect to the front of the engineering vehicle.

[0042] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0043] 1. The box forklift and flipping device of this utility model can realize the forklift and flipping (generally flipping 90°) of the box (such as cargo box), integrating the two functions. There is no need to configure an additional independent flipping mechanism, which avoids the bulky front structure of the engineering vehicle. It solves the problem that the traditional forklift device can only horizontally support the box and lacks the flipping function. When there is a need to flip the box, an additional independent flipping mechanism is required, which leads to the bulky front structure of the vehicle.

[0044] 2. The box forklifting and flipping device of this utility model flips the box over and then uses forks, protective baffles and semi-fixed baffles to fully protect the box from all sides, so as to achieve stable fixation of the box.

[0045] 3. The fork, protective baffle, and semi-fixed baffle of this utility model are all detachably connected. In the non-working state, the fork can be folded, and the baffle can be reversed or disassembled for storage, reducing the volume of the entire device and the engineering vehicle, reducing the space occupied, and reducing the overall size of the engineering vehicle and transport vehicle. When the engineering vehicle is transferred by other transport vehicles, it can prevent the outer contour of the box-lifting and flipping device of this utility model from exceeding the outline of the transport vehicle body, ensuring the road traffic capacity of the transport vehicle, improving the vehicle's flexibility and passability, and facilitating operation in confined spaces. It solves the problems of excessive transport vehicle volume and the obstruction of storage by the fixed baffle structure in the prior art. Moreover, the installation position of the fork, protective baffle, and semi-fixed baffle on the movable frame or fixed frame can be adjusted according to the size of the box, and modular design can be adopted to adapt to different sizes of boxes and to the box lifting and flipping in different environments, ensuring the adaptability and stability of the working environment, and solving the problem that the fixed baffle structure in the prior art cannot adapt to different sizes of boxes.

[0046] 4. This utility model provides driving force for the movable frame and the box to flip through a hydraulic cylinder. No other auxiliary equipment is needed. The hydraulic drive has sufficient driving force to ensure reliable operation of the box flipping.

[0047] 5. The foldable box-shaped forklift and tilting device of this utility model is integrated into the front of the engineering vehicle, which is compact and reasonable and facilitates integrated design.

[0048] 6. The present invention has a simple and reliable structure and low cost. On this basis, it simultaneously realizes the functions of forking and flipping, which is economical.

[0049] 7. This utility model can adapt to the forking and flipping of different boxes in the working state by adjusting the installation position of the fork, protective baffle and semi-fixed baffle. The storage of the fork, protective baffle and semi-fixed baffle saves the vehicle body size in the non-working state. Attached Figure Description

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0056] Example 1

[0057] As shown in Figures 1-4, this embodiment proposes a foldable box-shaped forklift and flipping device for engineering vehicles, including a fixing device 1 and a movable device 2.

[0058] The fixing device 1 includes a fixing frame, which is used to connect to the front of the engineering vehicle. The connection method is a fixed connection or a detachable connection.

[0059] In this embodiment, the fixing frame can be connected to the engineering vehicle by bolts or pins. When connected by pins, the fixing frame can be fixed by ensuring that the pin is interference-fitted with the connecting hole on the fixing frame and the engineering vehicle.

[0060] The movable device 2 includes a movable frame, which is rotatably connected to the fixed frame. A hydraulic cylinder 6 is connected between the movable frame and the fixed frame. By controlling the extension and retraction of the cylinder rod of the hydraulic cylinder 6, the movable frame can be driven to rotate relative to the fixed frame.

[0061] The bottom of the movable frame is connected to the front end of the fixed frame. The movable frame has a first position arranged vertically and a second position arranged horizontally after being flipped over. In Figure 1, the movable frame is in the first position, and in Figure 3, the movable frame is in the second position.

[0062] The movable frame can be flipped by the hydraulic cylinder 6. As needed, the movable frame can be driven to flip 90° relative to the fixed frame by the hydraulic cylinder 6.

[0063] In this embodiment, the bottom of the movable frame is connected to the fixed frame via pins. When connected by pins, ensuring a gap between the pins and the connecting holes on the movable and fixed frames allows for a rotatable connection between the movable frame and the fixed frame. As shown in Figure 2, the movable frame and the fixed frame are connected by three pins, one above the other. The two upper pins allow the movable frame to rotate, and these two pins are at the same height. The lower pin serves a fixing function; when the movable frame needs to be flipped, this pin is removed; when not flipping, the movable frame is fixed using this pin.

[0064] A fork 3 is connected to the movable frame, and the fork 3 is detachably connected to the movable frame.

[0065] The fork 3 has a third position perpendicular to the movable frame in the working state and a fourth position parallel to the movable frame in the stored state. In Figures 1 and 3, the fork 3 is in the third position, and in Figure 4, the fork 3 is in the fourth position.

[0066] When the movable frame is arranged vertically, one end of the fork 3 is connected to the bottom front end of the movable frame, and the fork 3 is perpendicular to the movable frame. At this time, the fork 3 is arranged horizontally, which facilitates the lifting of the box. Thus, the box can be horizontally supported by the fork 3. When it is necessary to flip the box, the cylinder rod of the hydraulic cylinder 6 is controlled to retract, driving the movable frame to flip to a horizontal state. At this time, the box is flipped and supported by the movable frame. The fork 3 flips to a vertical state with the movable frame. At this time, the fork 3 protects and stops one side of the box.

[0067] In this embodiment, the fork 3 is detachably connected to the movable frame in the following way: the fork 3 is connected to the movable frame via a pin. When connected via a pin, ensuring an interference fit between the pin and the connecting holes on the movable frame and the fork 3 is sufficient to fix the fork 3. Removing the pin allows the fork 3 to be removed from the movable frame. After removing the pin, the installation state of the fork 3 can be adjusted. When the box needs to be lifted, the fork 3 is arranged horizontally and connected to the front end of the movable frame for easy lifting. In the non-working state, the fork 3 is arranged vertically and connected to the front end of the movable frame. At this time, the fork 3 is parallel to the movable frame, allowing the fork 3 to be folded and stored, reducing space occupation and transportation volume, and preventing the fork 3 from exceeding the vehicle's body outline. Alternatively, the fork 3 can be directly removed.

[0068] A protective baffle 4 is connected to the movable frame, and the protective baffle 4 is detachably connected to the movable frame. When the movable frame is arranged vertically, a protective baffle 4 is connected to each of the left and right sides of the movable frame. One end of the protective baffle 4 is connected to the movable frame, and the protective baffle 4 is perpendicular to the movable frame. The protective baffle 4 has a fifth position in which it extends beyond the front end of the movable frame in the working state and a sixth position in which it does not extend beyond the front end of the movable frame in the stored state. In Figures 1 and 3, the protective baffle 4 is in the fifth position, and in Figure 4, the protective baffle 4 is in the sixth position.

[0069] In this embodiment, one end of the protective baffle 4 is connected to the side of the movable frame, and the protective baffle 4 is perpendicular to the movable frame. At this time, the protective baffle 4 is arranged horizontally. When the box is picked up by the fork 3 and carried horizontally, the protective baffle 4 protects and stops both sides of the box. When the box needs to be flipped, the cylinder rod of the hydraulic cylinder 6 is controlled to retract, driving the movable frame to flip to a horizontal state. At this time, the box is flipped and carried by the movable frame. The fork 3 and the protective baffle 4 both flip to a vertical state with the movable frame. At this time, the fork 3 protects and stops one side of the box, and the protective baffle 4 protects and stops both sides of the box.

[0070] In this embodiment, the protective baffle 4 is detachably connected to the movable frame in the following way: the protective baffle 4 is connected to the movable frame via a pin. When connected via a pin, ensuring an interference fit between the pin and the connecting holes on the movable frame and the protective baffle 4 is sufficient to fix the protective baffle 4. Removing the pin allows the protective baffle 4 to be removed from the movable frame. After removing the pin, the installation state of the protective baffle 4 can be adjusted. When the box needs to be forked, the protective baffle 4 is horizontally arranged and connected to the side of the movable frame for easy protection of the box. In the non-working state, the other end of the protective baffle 4 is connected to the side of the movable frame, ensuring that the protective baffle 4 no longer protrudes from the front end of the movable frame. The protective baffle 4 can be reversed and stored to reduce space occupation, reduce transportation volume, and prevent the protective baffle 4 from exceeding the vehicle's body outline. Alternatively, the protective baffle 4 can be directly removed.

[0071] The protective baffle 4 is not limited to being connected to both sides of the movable frame. The distance between the two protective baffles 4 can be adjusted, and then they can be connected to the movable frame to adjust the clamping space to accommodate the forklifting of boxes of different widths, as well as to protect the boxes during the flipping process.

[0072] A semi-fixed baffle 5 is detachably connected to the fixed frame. The semi-fixed baffle 5 is arranged vertically and is used to protect and stop the other side of the overturned box. The fork 3, the protective baffle 4, and the semi-fixed baffle 5 provide comprehensive protection around the overturned box, thereby achieving stable fixation of the box.

[0073] In this embodiment, the semi-fixed baffle 5 is connected to the fixing frame by bolts. The semi-fixed baffle 5 can be removed by unscrewing the bolts. In the non-working state, the semi-fixed baffle 5 can be removed without installation, that is, it can be disassembled and stored to reduce the vertical space occupation and avoid affecting the road traffic capacity of transport vehicles.

[0074] The lower end of the semi-fixed baffle 5 is provided with multiple bolt holes 7, and the fixing frame is also provided with bolt holes for connecting the semi-fixed baffle 5. By aligning the different bolt holes 7 on the semi-fixed baffle 5 with the bolt holes on the fixing frame and installing bolts in the holes, different installation heights of the semi-fixed baffle 5 can be achieved, and the protective height of the semi-fixed baffle 5 can be adjusted.

[0075] In this embodiment, the fixed frame and the movable frame can be steel structure frames.

[0076] The container forklift and flipping device of this utility model can realize the forklift and flipping (generally flipping 90°) of the container (such as cargo box), integrating the two functions, eliminating the need for an additional independent flipping mechanism and avoiding the bulky front structure of the engineering vehicle.

[0077] The box-lifting and flipping device of this utility model flips the box over and then uses the fork 3, protective baffle 4 and semi-fixed baffle 5 to fully protect the four sides of the box, so as to achieve stable fixation of the box.

[0078] The fork 3, protective baffle 4, and semi-fixed baffle 5 of this utility model are all detachably connected. In the non-working state, the fork 3 can be folded, and the baffle can be reversed or disassembled for storage, reducing the volume of the entire device and the engineering vehicle, reducing the space occupied, and reducing the overall size of the engineering vehicle. When the engineering vehicle is transferred by other transport vehicles, it can prevent the outer contour of the box lifting and flipping device of this utility model from exceeding the outline of the transport vehicle, ensuring the road traffic capacity of the transport vehicle, improving the vehicle's flexibility and passability, and facilitating operation in confined spaces. Moreover, the installation position of the fork 3, protective baffle 4, and semi-fixed baffle 5 on the movable or fixed frame can be adjusted according to the size of the box, and modular design can be adopted to adapt to different sizes of boxes and to the box lifting and flipping in different environments, ensuring the adaptability and stability of the working environment.

[0079] The fork 3 and protective baffle 4 of this utility model can also be connected to the movable frame through an intermediate connector. The connection position of the fork 3 and protective baffle 4 on the intermediate connector can be changed by opening multiple connection holes on the intermediate connector, so as to change the position of the fork 3 and protective baffle 4 relative to the movable frame. The intermediate connector can adopt a connecting plate, connecting seat or other structure.

[0080] This invention provides driving force for the movable frame and the box to flip through a hydraulic cylinder 6. No other auxiliary equipment is needed. The hydraulic drive provides sufficient driving force to ensure reliable operation of the box flipping.

[0081] The present invention integrates a foldable box-shaped forklift and tilting device for engineering vehicles at the front end of the engineering vehicle. The arrangement is compact and reasonable, and facilitates integrated design.

[0082] This utility model has a simple and reliable structure, low cost, and simultaneously realizes the functions of forking and flipping, making it economical.

[0083] This utility model can adapt to the forking and flipping of different boxes during the working state by adjusting the installation positions of the fork 3, protective baffle 4 and semi-fixed baffle 5. The storage of the fork 3, protective baffle 4 and semi-fixed baffle 5 saves the vehicle body size when not in operation.

[0084] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
