[0014] In a possible design, the conveying frame is fixedly provided with the placing frame on the bottom.

[0015] In the present application, when starting to use, first move the device as a whole to the position where it is needed to be used (the position where the goods train loads and unloads materials) through the moving wheels, and place the side of the conveying frame with the casters close to the carriage opening (at this time, the device as a whole is in an unfolded state as shown in Figures 1-3 Then, connect the power supply of the device as a whole, and then rotate the knobs in sequence. In the process of rotating the knobs, the threaded rods are driven to move downward on the fixed frame, so as to drive the support pads at the bottom thereof to approach the ground, until the support pads and the rubber anti-skid pads at the bottom thereof are in contact with and abut against the ground, so as to complete the position limitation of the device as a whole.

[0016] When the conveying height of the conveying frame is lower than the carriage, the pull handle is pulled first, the pull handle pulls the pin rod outwards at the same time, the pin rod pulls the gear plate to move synchronously at the same time (the spring is deformed under stress), so that the gear plate is disengaged from the clamping of the tooth block on the connecting seat, at this time the hydraulic push rod is started, the output end of the hydraulic push rod is extended and pushes one side of the conveying frame to rise through the support one, the connecting seat rotates around the rotating shaft to change the angle of one side of the conveying frame in the conveying process, at the same time the supporting leg also rotates on the support two to change the conveying angle of the conveying frame in cooperation with the rising of the hydraulic push rod, until the whole conveying frame is raised to be flush with the carriage opening, then the pull handle is released, at this time the spring is pulled by the elastic principle of itself, then the materials near the carriage opening are placed on the conveying frame and conveyed outwards by the electric rotating roller, the pin rod is reset, the pin rod pulls the gear plate on it to reset at the same time, so that the gear plate and the tooth block are clamped again, and the connecting seat is locked to place the hydraulic push rod in the conveying process.

[0017] When the conveying of the materials near the carriage opening is completed, the materials in the carriage need to be conveyed, the pull handle is continuously pulled, the gear plate is disengaged from the clamping between the tooth blocks, the hydraulic push rod is started again, the conveying end of the hydraulic push rod continues to push the conveying frame to rise, when the casters at the bottom of the conveying frame are higher than the bottom plate of the carriage, the whole conveying frame is pushed, so that the conveying frame moves to the inside of the carriage through the moving wheels, then the output end of the hydraulic push rod is retracted by starting the hydraulic push rod, as the output end of the hydraulic push rod is retracted, the casters slowly approach the bottom plate of the carriage and contact the bottom plate, at this time the output end of the hydraulic push rod continues to retract to the initial state, then the hydraulic push rod is rotated, so that the moving wheels at the bottom of the hydraulic push rod are disengaged from the ground, until the hydraulic push rod is attached to the bottom of the conveying frame, at this time the pull handle is released, so that the gear plate and the tooth block are clamped again, so that the position of the hydraulic push rod is locked through the connecting seat, to prevent the hydraulic push rod from being suddenly expanded to affect the operation, then the conveying frame is continuously pushed, the conveying frame moves to the inside of the carriage through the casters to carry out loading and unloading work.

[0018] When the height of the materials accumulated in the carriage is too high, the hydraulic cylinder is started first (at this time the hydraulic cylinder needs to be manually held, because the height of the hydraulic cylinder is lower than the casters), the output end of the hydraulic cylinder is extended, so that the bottom of the hydraulic cylinder moves downwards until it abuts against the bottom plate of the carriage, then the hydraulic cylinder continues to work to lift the conveying frame, when the conveying frame is lifted to the appropriate height, the hydraulic push rod is rotated to abut against the bottom plate of the carriage and lock the position, and the hydraulic push rod is started to push the conveying frame to rise, when the height of the conveying frame is suitable for the conveying of the materials, the work of the electric push rod is stopped, so that the conveying frame is attached to the placing height of the materials, and is close to the best operating position of the operator, effectively reducing the stress stroke of direct manual carrying.

[0019] The utility model has the advantages of the following:

[0020] The utility model discloses a flexible adjustment of conveying frame is realized, makes it can adapt to the carriage of different height and the operation surface loading and unloading demand, and then close to the best operation body position of operating personnel, effectively reduced the stress journey of manpower direct handling, improved the comfort and security of man-machine collaborative operation, and the potential harm to human function is reduced to the maximum simultaneously.

[0021] The utility model discloses the setting through limiting mechanism, realized the position locking of the unfolding or storage state of lifting mechanism, can effectively fix the position after height adjustment, prevent the structural sway of the deviation of hydraulic push rod in the operation process, can also ensure the overall stability of device after storage, avoid the accidental loosening when moving or depositing, thereby improve the security, durability and operation efficiency of equipment.

[0022] The utility model discloses the combination through lifting mechanism and limiting mechanism, realized the collaborative operation of conveying frame height flexible adjustment and accurate position locking, significantly improved the adaptability, stability and operation safety of device.
