Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic platforms, in particular to a detachable box car suitable for both rail transportation and single-hook crane transportation. Background Art

[0002] The practical application of box trucks for material transportation presents many urgent problems. On the one hand, most existing box trucks are relatively simple in function and can often only adapt to one of the following modes of transportation: rail transportation or single-hook crane transportation. If there is a need to switch between different transportation scenarios, it is necessary to replace the dedicated vehicle, which not only significantly reduces transportation efficiency but also increases the purchase cost of the equipment. On the other hand, existing box trucks lack flexible height adjustment mechanisms when loading and unloading goods, making it difficult to accurately connect with transportation platforms or loading and unloading equipment at different heights, which greatly affects the convenience of loading and unloading operations.

[0003] Furthermore, existing box trucks lack adequate protective structures. During transport, cargo can easily shake or even slip, posing a significant safety hazard. Furthermore, when loading and unloading with forklifts and other equipment, there are no effective deceleration or limiters, potentially leading to collisions and other accidents. Furthermore, the structure of traditional box trucks is mostly fixed, making it impossible to adjust the platform's tilt angle based on actual loading and unloading needs. This makes them significantly less practical for certain loading and unloading scenarios. Summary of the Invention

When switching between different transportation scenarios, there is no need to change vehicles, which greatly improves transportation efficiency and reduces the cost of equipment use.

[0015] Flexible Lift Adjustment: Two pairs of lifting mechanisms and linkage components work together, driven by the first hydraulic cylinder, to precisely raise and lower the lift plate. This allows the box truck to easily dock with transport platforms or loading and unloading equipment at different heights, greatly enhancing the convenience of loading and unloading operations.

[0016] Precise Tilt Angle Control: The first hydraulic cylinder in the linkage assembly supports differentiated control, allowing the platform to assume different positions, such as left-side tilt, horizontal position, or right-side tilt.

[0018] Secondary protective structure: An electric slide drives the bottom plate, which in turn, via a support rod, pushes the flap upward within the opening, creating a speed bump. When the lift plate tilts, this speed bump acts as a decelerator and shield for forklifts and other loading and unloading equipment, effectively preventing accidents such as collisions and rollovers caused by excessive speed, significantly improving the safety of loading and unloading operations.

[0019] Convenient movement and operation: The universal wheels at the bottom of the vehicle body allow the operator to push the vehicle through the handrails, so that the vehicle can easily reach the designated location; the controller setting realizes centralized control of equipment lifting, tilting and other functions, which is simple and convenient to operate and reduces the workload of the operator.

The lifting plate 71 is fixedly arranged on the second flip seat 54 at the top of the fork rod group 51, and the lifting plate 71 is opposite to the vehicle body 1. A lifting port 10 is opened in the middle of the front and rear ends of the lifting plate 71, and a flip port 11 is opened through the lifting plate 71 near the left and right ends. The pair of brackets 7272 are both concave, and the two ends of the pair of brackets 7272 are fixedly arranged on the lower walls of the front and rear ends of the lifting plate 71, and the bearing plate 73 is fixedly arranged on the lower walls of the front and rear ends of the lifting plate 71. The two ends are respectively fixed on the middle part of the bracket 72, one end of a pair of second hydraulic cylinders 74 is respectively fixed through the front and rear ends of the carrying plate 73, and the telescopic ends of the second hydraulic cylinders 74 are respectively opposite to the middle of the lifting port 10, one end of a pair of railings 75 is respectively fixed on the telescopic ends of the second hydraulic cylinders 74, and the other ends of the railings 75 are respectively movable through the lifting port 10, the upper and lower ends of the railings 75 are rectangular cylinders, and a number of vertical poles are equidistantly arranged in the middle; the carrying plate 73 is installed through the bracket 72, and the second hydraulic cylinder 74 and the second protective structure 8 are installed through the carrying plate 73, and the railings 75 are driven to move through the lifting plate 71 through the telescopic second hydraulic cylinder 74.

[0027] As a further solution of the present invention, the second protective structure 8 includes a pair of flip plates 81, a pair of electric slide rails 82, a pair of bottom plates 83, two pairs of third flip seats 84 and two pairs of support rods 85; one end of the pair of flip plates 81 is movably embedded in the flip opening 11 of the lifting plate 71, and the pair of electric slide rails 82 are symmetrically arranged on the upper wall of the bearing plate 73, and the electric slide rails 82 are close to the front and rear ends of the flip plate 81, and a pair of bottom plates 83 are horizontally fixed on the electric slide rails 82, and one end of the two pairs of third flip seats 84 are fixed on the bottom plate 83 and are respectively located on the right side of the flip plate 81, and one end of the two pairs of support rods 85 are movably connected to the third flip seat 84, and the other end of the support rods 85 are movably connected to the lower wall of the flip plate 81 towards the upper left; the bottom plate 83 is driven to move left and right by the electric slide rails 82, and then the support rods 85 are driven to apply force to the flip plate 81 through the third flip seat 84, so that the flip plate 81 is flipped upward by a certain angle in the lifting plate 71 to form a speed bump shield.

[0028] As a further solution of the present invention, when the bottom plate 83 moves to the left, the other end of the flap 81 flips upward, which is used for design control requirements, and when in use, the flipping direction of the flap 81 is opposite to the high side of the slope formed by the lifting plate 71.

[0029] As a further solution of the present invention, the first hydraulic cylinder 61 in the linkage assembly 6 is controlled separately to control and adjust the horizontality or inclination of the lifting plate 71.

[0030] As a further solution of the present invention, the left end of the lifting plate 71 is tilted downward or horizontal, or the right end is tilted downward, so as to realize adjustment according to the environment of loading, unloading and transportation according to design requirements.

[0031] Working principle: The operator pushes the vehicle body 1 by applying force through the handrail 4, and realizes flexible movement with the help of the universal wheels 2 at the four corners of the lower wall of the vehicle body. After positioning the equipment at the target position, the power cord is connected through the controller 3 to power the hydraulic system and the electric component; after the controller 3 is started, the first hydraulic cylinder 61 in the linkage assembly 6 starts to work; when the telescopic end of the first hydraulic cylinder 61 extends forward, it pushes the drive frame 62 through the drive slot 9 at the front end of the vehicle body, driving the first slide bar 63 to move forward; the first slide bar 63 passes through the telescopic hole of the adapter seat 52 at the bottom end of the fork rod group 51, and is connected to the bottom through the mounting bolt 55 The adapter seat 52 on the front side of the bottom is fixed; when the first slide bar 63 moves forward, the adapter seat 52 on the rear side of the bottom slides backward on the first slide bar 63, prompting the connecting rod of the fork arm group 51 to cross-flip, driving the adapter seat 52 at the top to lift upward; at the same time, the second slide bar 64 at the top of the fork arm group 51 fixes the front adapter seat 52, and the rear adapter seat 52 slides on the first slide bar 63 to ensure the stability of the lifting process; finally, the second flip seat 54 at the top of the fork arm group 51 drives the lifting plate 71 to rise synchronously; conversely, when the first hydraulic cylinder 6161 contracts, the lifting plate 71 descends.

[0032] The left and right first hydraulic cylinders 61 in the linkage assembly 6 can be controlled separately. When the left end of the lifting plate 71 needs to be tilted down, the left first hydraulic cylinder 61 contracts, driving the left fork rod group 51 to descend, and the right first hydraulic cylinder 61 remains extended, and the right fork rod group 51 maintains its height. The left end of the lifting plate 71 is tilted down by the flipping of the second flip seat 54 on the first flip seat 53; conversely, the right end is tilted down when the right first hydraulic cylinder 61 contracts; when the first hydraulic cylinders 61 on both sides act synchronously, the lifting plate 71 remains horizontal.

[0033] The tilt angle adjustment can adapt to the platform height difference in rail transportation or the need for cargo to slide during single hook lifting and unloading. For example, the lifting plate 71 is adjusted to the left end to tilt downward to facilitate the sliding of cargo from high to low.

[0034] When the lifting platform 71 is in place, the second hydraulic cylinder 74 in the first protective structure 7 is activated, and its telescopic end pushes the railing 75 upward, causing the railing to rise through the lifting openings 10 at the front and rear ends of the lifting platform 71. The rectangular columns at the upper and lower ends of the railing 75 and the central vertical rod form a protective barrier to prevent the goods from shaking or sliding during transportation.

[0035] When loading and unloading goods or using a forklift, the second hydraulic cylinder 74 contracts and the railing 75 descends to below the lifting plate 71 to avoid blocking the transport path.

[0036] Conditions for deploying the speed bump: When the lifting plate 71 is tilted, in order to prevent a forklift from colliding due to acceleration caused by the slope when loading and unloading goods, the electric slide rail 82 in the second protective structure 8 is activated; the electric slide rail 82 drives the bottom plate 83 to move to the left, and the bottom plate pushes the support rod 85 through the third flip seat 84. The support rod tilts and applies force to the upper left, causing the flap 81 to flip upward in the flip opening 11 of the lifting plate, forming a stepped speed bump. The flipping direction of the flap 81 is opposite to the higher side of the slope of the lifting plate. For example, when the left end of the lifting plate 71 tilts downward, the left flap 81 flips upward to prevent the forklift from sliding down quickly.

[0037] Speed ​​bump retracted state: when the electric slide rail 82 drives the bottom plate 83 to move to the right, the support rod 85 pulls the flap 81 back into the lifting plate 71, which does not affect normal transportation.

[0038] Rail transport mode: the lifting platform 71 remains horizontal, the railing 75 is raised to protect the goods, and the vehicle body 1 moves on the track through the universal wheels 2 to adapt to the track roadbed height.

[0039] Single hook lifting transport mode: When single hook lifting is required for loading and unloading, the lifting plate 71 is adjusted to a suitable height through the linkage assembly 6, and the flap 81 of the second protective structure 8 is used to form a temporary support surface to cooperate with the hook to complete the cargo lifting; or by tilting the lifting plate 71, the cargo can slide along the slope to the designated position.

[0040] Through the coordinated operation of the above components, the box truck realizes the integrated control of transportation scene switching, height and angle adjustment, safety protection and other functions, thereby improving the flexibility and safety of material transportation.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
