Technical Field

[0001] The utility model relates to the technical field of train loading machines, in particular to a loading machine capable of accurately controlling a stacking position. Background Art

[0002] Train transportation is a very common form of logistics. The advantage of train transportation is that it can transport a huge amount of goods. Since a large amount of goods can be transported in a single batch, when loading goods, in order to make full use of the storage space inside the carriage, the goods need to be stacked as compactly and as high as possible. Conventional cargo stacking mainly relies on manpower, which is labor-intensive and cannot guarantee the accuracy of cargo stacking. Once the upper and lower cargo bags are not aligned, they will take up space, which will affect the subsequent bag stacking. Therefore, a loader that can accurately control the stacking position is proposed. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a loader which can accurately control the stacking position.

[0009] In a preferred technical solution, the guide frame is a U-shaped structure, and guide bars, mold racks and a second rigid chain are arranged in the guide frame. The guide bars are provided in two groups, and the guide bars are arranged along the inner wall surface of the guide frame and remain parallel. The mold rack is fixedly installed in the guide frame, and the sliding direction of the mold rack is parallel to the extension direction of the guide bars.

[0010] In a preferred technical solution, a rotating motor is disposed inside the stacking platform, a gear is disposed at the output end of the rotating motor, the gear is meshed with the mold rack for transmission, and a sliding seat slidably matched with the guide bar is disposed on the stacking platform.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In this embodiment, refer to Figure 1-4 A loader capable of precisely controlling the stacking position comprises a vehicle body 1, a gantry frame 2 being arranged at the rear of the vehicle body 1, a guide frame 3 which slides vertically being mounted on the gantry frame 2 through a rigid chain elevator, a stacking platform 4 which slides horizontally being mounted in the guide frame 3, a plurality of sequentially arranged conveyor belts 5 being arranged on the surface of the stacking platform 4, and bags 6 to be conveyed being placed on the conveyor belts 5.

[0021] Combined with Figure 2 The structure of the rigid chain elevator is described below. As shown in the figure, the rigid chain elevator includes a servo motor 201, a belt 202 and a first rigid chain 203. The gantry frame 2 is provided with a rotating shaft 204 rotatably installed near its top wall and bottom wall. Both ends of the upper and lower rotating shafts 204 are respectively connected with coaxially rotating sprockets. The outer peripheries of the sprockets aligned up and down on the same side are kept in synchronous transmission through the first rigid chain 203.

[0022] The output end of the servo motor 201 is provided with a rotating wheel, and another rotating wheel is sleeved on the shaft of the rotating shaft 204 at the top. The upper and lower rotating wheels are aligned and synchronously driven by the belt 202. The servo motor 201 is driven to control the rotation of the rotating wheel at its output end, and the upper rotating shaft 204 and the sprocket wheels at both ends are controlled to rotate through the transmission of the belt 202. Since the transmission is maintained between the upper and lower sprocket wheels through the first rigid chain 203, the first rigid chains 203 on the left and right sides will maintain synchronous transmission.

[0023] Here, the servo motor 201 can rotate forward and reverse to control the forward transmission or reverse transmission of the two first rigid chains 203. It should be noted that the outer surfaces of the two arms of the gantry frame 2 are provided with slide grooves that slide vertically, the guide frame 3 is provided with a slider that matches the slide groove, and the inner surface of the guide frame 3 is fixedly connected to the first rigid chain 203.

[0024] The guide frame 3 is fixedly connected to the first rigid chain 203, so the guide frame 3 can be vertically raised and lowered with the forward and reverse transmission of the first rigid chain 203, and finally the height of the stacking platform 4 installed in the guide frame 3 can be adjusted. The vertical position adjustment of the stacking platform 4 is the adjustment of the stacking height, and the bags 6 can be stacked at different heights.

[0025] As attached Figure 3 or attached Figure 4As shown, the guide frame 3 is a U-shaped structure, and a guide bar 301, a mold rack 302 and a second rigid chain 303 are arranged in the guide frame 3. Two groups of guide bars 301 are arranged along the inner wall surface of the guide frame 3 and remain parallel. The mold rack 302 is fixedly installed in the guide frame 3, and the sliding direction of the mold rack 302 is parallel to the extension direction of the guide bar 301.

[0026] The guide bar 301 and the mold rack 302 are both fixedly installed. A rotating motor 401 is arranged inside the stacking platform 4. A gear 403 is arranged at the output end of the rotating motor 401. The gear 403 and the mold rack 302 are meshed and transmitted. The rotation of the gear 403 is controlled by the rotating motor 401, so that the gear 403 can translate along the length direction of the mold rack 302 during the rotation process.

[0027] It should be noted that a sliding seat 402 that is slidably matched with the guide bar 301 is provided on the stacking platform 4. In addition, one end of the second rigid chain 303 is fixed to the bottom wall of the guide frame 3, and the other end of the second rigid chain 303 is provided with a connecting seat 304, the inner surface of the connecting seat 304 is connected to the mold rack 302, and the outer surface of the connecting seat 304 is connected to the stacking platform 4. As the gear 403 rotates, the sliding seat 402 and the second rigid chain 303 are designed to provide stability for the stacking platform 4 during translation while ensuring that the stacking platform 4 translates in a straight line.

[0028] The stacking platform 4 can adjust the stacking height of the bags 6 according to actual conditions, and can also adjust the stacking position of the bags 6 in the horizontal direction, accurately placing the bags 6 at the specified position, ensuring that the upper and lower bags 6 are aligned, and making full use of the storage space inside the car.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
