Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a lifting device for a support transport vehicle. Background Technology

[0002] Support transport vehicles are key transportation equipment used in mining, tunneling, and other engineering fields for moving heavy hydraulic supports and other large equipment. The lifting device, as the core component of the support transport vehicle, primarily functions to vertically lift materials, facilitating loading, transportation, and unloading operations. An efficient and stable lifting device is crucial for ensuring the transport vehicle's working efficiency and operational safety.

[0003] Currently, most common lifting devices employ hydraulic cylinders or chain lifting structures. However, in practical applications, especially when handling materials of considerable length, existing technologies have certain limitations. When the lifting platform descends to a lower position, the ends of the material easily come into contact with and rub against the vehicle frame, increasing movement resistance and making it difficult to position the material. This also increases the risk of scratching and damaging the material or equipment surface. Furthermore, during loading and unloading, operators often need to repeatedly adjust the material's position using external force, a time-consuming and labor-intensive process that poses safety hazards and affects the overall smoothness and efficiency of the handling operation. Utility Model Content

[0004] This utility model relates to a novel lifting device that can effectively solve the problem of poor sliding of long materials during low-level loading and unloading.

[0005] The technical solution adopted by this utility model is as follows: a lifting device for a support transport vehicle, comprising an L-shaped frame, a lower base plate and an upper top plate fixedly connected to the bottom and top of one side of the L-shaped frame, respectively; a motor fixedly installed on one side of the upper top plate, the output shaft of the motor passing through the upper top plate and fixedly connected to a first transmission wheel; a second transmission wheel rotatably connected to one side of the lower base plate; the first transmission wheel and the second transmission wheel are connected by a transmission belt; two vertically arranged fixed uprights are fixedly connected to the inner side wall of the L-shaped frame; an L-shaped lifting plate is slidably connected to one side of the two fixed uprights; and a connecting seat fixedly connected to the transmission belt is fixedly connected to one side of the L-shaped lifting plate.

[0006] As a further improvement of this utility model, a plurality of support seats are fixedly installed at the bottom of the L-shaped frame. The number of support seats is four and they are distributed in a rectangular pattern at the four corners of the bottom of the L-shaped frame.

[0007] As a further improvement of this utility model, the bottom wall of the L-shaped frame is provided with an opening directly below the L-shaped lifting plate, and the size of the opening is larger than that of the L-shaped lifting plate.

[0008] As a further improvement of this utility model, strip boxes are fixedly connected to both sides of the opening on the bottom wall of the L-shaped frame, and several guide wheels are rotatably connected inside the strip boxes to facilitate the sliding of materials.

[0009] As a further improvement of this utility model, a rotating shaft is fixedly inserted inside the second transmission wheel, and one end of the rotating shaft is rotatably connected to the lower base plate through a bearing.

[0010] As a further improvement of this utility model, the two fixed uprights are fixedly installed with slide rails on the side near the L-shaped lifting plate, and the L-shaped lifting plate is fixedly connected with two sliders that are respectively adapted to the slide rails on the side near the two fixed uprights.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a motor to drive the transmission wheel and transmission belt, which drives the L-shaped lifting plate to rise and fall steadily along the fixed upright, thus achieving a smooth and controllable lifting process. In particular, the opening at the bottom of the L-shaped frame and the guide wheel structure on both sides allow materials of greater length to smoothly contact and roll on the guide wheels after their ends extend out of the lifting plate when lifting or lowering them. This greatly reduces frictional resistance and avoids scratching damage between the materials and the frame, thereby significantly improving the convenience, efficiency, and safety of loading and unloading long materials. The overall structural design is reasonable and highly practical. Attached Figure Description

[0017] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0018] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides the following: Figure 1-4 The lifting device for a support transport vehicle shown includes an L-shaped frame 1. A lower base plate 2 and an upper top plate 3 are fixedly connected to the bottom and top ends of one side of the L-shaped frame 1, respectively. A motor 4 is fixedly installed on one side of the upper top plate 3. The output shaft of the motor 4 passes through the upper top plate 3 and is fixedly connected to a first transmission wheel 5. A second transmission wheel 6 is rotatably connected to one side of the lower base plate 2. The first transmission wheel 5 and the second transmission wheel 6 are connected by a transmission belt 7. Two vertically arranged fixed uprights 8 are fixedly connected to the inner side wall of the L-shaped frame 1. An L-shaped lifting plate 9 is slidably connected to one side of the two fixed uprights 8. A connecting seat 10, which is fixedly connected to the transmission belt 7, is fixedly connected to one side of the L-shaped lifting plate 9.

[0021] like Figure 1 and Figure 2 As shown, in this utility model, a plurality of support seats 11 are fixedly installed at the bottom of the L-shaped frame 1. The number of support seats 11 is four and they are distributed in a rectangular shape at the four corners of the bottom of the L-shaped frame 1.

[0022] like Figure 1 and Figure 2As shown, in this invention, the bottom wall of the L-shaped frame 1 has an opening directly below the L-shaped lifting plate 9, and the opening size is larger than the L-shaped lifting plate 9. This opening design allows the horizontal part of the L-shaped lifting plate 9 to completely sink below the bottom wall of the L-shaped frame 1 when it descends to its lowest position, thereby reducing the initial height for loading and unloading materials and facilitating the stable placement of long materials on the L-shaped lifting plate 9. A strip box 12 is fixedly connected to both sides of the opening on the bottom wall of the L-shaped frame 1. Several guide wheels 13 are rotatably connected inside the strip box 12 to facilitate material sliding. The wheel surface of the guide wheel 13 is slightly higher than the upper surface of the bottom wall of the L-shaped frame 1. When the ends of the long material extend beyond the edge of the L-shaped lifting plate 9, the bottom of the material can contact the guide wheel 13. During the process of the material rising and falling with the L-shaped lifting plate 9 or being manually adjusted in position, the guide wheel 13 rolls accordingly, converting the sliding friction between the material and the frame into rolling friction, effectively reducing resistance.

[0023] like Figure 2-4 As shown, in this utility model, a rotating shaft is fixedly inserted inside the second transmission wheel 6, and one end of the rotating shaft is rotatably connected to the lower base plate 2 through a bearing. The bearing ensures the flexibility of the rotation of the second transmission wheel 6 and reduces mechanical losses during the transmission process.

[0024] like Figure 1 , Figure 3 , Figure 4 As shown, in this utility model, two fixed uprights 8 are fixedly installed with slide rails 14 on the side near the L-shaped lifting plate 9. Two sliders 15, which are respectively adapted to the slide rails 14, are fixedly connected to the side of the L-shaped lifting plate 9 near the two fixed uprights 8. The sliders 15 are embedded in the slide rails 14 and slide along their length, providing precise guidance for the lifting movement of the L-shaped lifting plate 9, preventing the L-shaped lifting plate 9 from deviating or shaking during movement, and further improving the stability of the device operation.

[0025] Working Principle: In practical implementation, the long material to be transported is first placed on the horizontal surface of the L-shaped lifting plate 9. If the material is long, both ends will naturally extend above the strip box 12 and contact the guide wheels 13. The motor 4 is started, and its output shaft drives the first transmission wheel 5 to rotate. This, in turn, drives the second transmission wheel 6 to rotate synchronously via the transmission belt 7. During this movement, the transmission belt 7 drives the L-shaped lifting plate 9 to slide upwards along the slide rail 14 on the fixed upright 8 via the connecting seat 10, thus lifting the material. When it is necessary to lower the material, the motor 4 is reversed, and the L-shaped lifting plate 9 slowly descends with the transmission belt 7 under gravity until the material is placed in the designated position or the L-shaped lifting plate 9 reaches its lowest position. Throughout this process, the guide wheels 13 assist the material in maintaining smooth sliding, preventing jamming or scraping. The entire operation is simple, efficient, and safe, effectively solving the problems of traditional lifting devices when loading and unloading long materials at low positions.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
