Description

Technical Field

[0001] This utility model relates to the technical field of fixed lifting platforms, specifically a fixed lifting platform that facilitates cargo positioning. Background Technology

[0002] Fixed lifting platforms are vertical transportation equipment installed in a specific location and not moved arbitrarily. They are mainly used for the vertical transportation of goods or personnel. Lifting functions are primarily achieved through mechanical transmission or hydraulic drive. For example, a scissor lift platform consists of multiple sets of cross linkages (scissor arms). A motor-driven screw or hydraulic cylinder pushes the scissor arms to unfold / fold, achieving vertical movement of the platform. In the existing technology, the authorized publication number CN 221343828... U proposes a fixed lifting platform structure for easy loading and unloading of goods, including a body, a lifting assembly on the body, a lifting platform on the top of the lifting assembly, a loading and unloading platform on the lifting platform, rollers at the bottom of the loading and unloading platform, the rollers being rotatably connected to the top of the lifting platform, symmetrically slidably connected assist blocks on the lifting platform, and symmetrically provided slots at the bottom of the loading and unloading platform for use with the assist blocks, the slots including a front stop block and a rear stop block, with the assist blocks located between the front stop block and the rear stop block. Although this facilitates loading and unloading of goods, during the loading and unloading process, in order to prevent the goods from tilting and falling during the lifting process, it is necessary to use a chock or strap to position the goods, which takes a lot of time. Even if some platforms have railings on the outer edge to prevent the goods from falling, the space enclosed by the railings is limited, and when there are few goods, the goods are prone to tilting. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a fixed lifting platform for easy cargo positioning, including a fixed base 1, a support arm 2 at the upper end of the fixed base 1, a carrying platform 3 at the upper end of the support arm 2, a mounting seat rotatably connected inside the fixed base 1 via a rotating shaft, an electro-hydraulic actuator on the surface of the mounting seat, the telescopic end of the electro-hydraulic actuator being rotatably connected to the scissor arm of the support arm 2 via a rotating shaft, the support arm 2 adopts the scissor arm structure of a common scissor lift in the prior art, the support arm 2 is composed of multiple scissor arms, the scissor arm 2 is pushed by the electro-hydraulic actuator to unfold or fold, realizing the lifting movement of the carrying platform 3, driving the cargo placed on the surface of the carrying platform 3 to lift and lower, and also includes a positioning mechanism 4;

[0021] Positioning mechanism 4 includes a horizontal baffle 41, a vertical baffle 42, a limiting plate 43, and a limiting insert 44. The horizontal baffles 41 are respectively disposed at the front and rear ends of the upper surface of the bearing platform 3. The inner surfaces of the two horizontal baffles 41 are each provided with a limiting plate 43. The vertical baffles 42 are slidably connected laterally between the two horizontal baffles 41. The outer surfaces of the two vertical baffles 42 are slidably connected longitudinally with limiting inserts 44. The limiting inserts 44 are slidably connected longitudinally inside the guide frame on the surface of the vertical baffles 42. 4. When the goods are placed on the upper surface of the carrying platform 3, the left and right positions of the longitudinal baffle 42 are adjusted. After the adjustment is completed, the limiting plate 44 is inserted into the limiting slot on the surface of the limiting plate 43 to restrict the position of the longitudinal baffle 42 and provide space for the placement of the goods. After the placement is completed, for goods in regular boxes or bags, the horizontal baffle 41 and the longitudinal baffle 42 can be used to surround the goods and position the goods horizontally on the surface of the carrying platform 3.

[0022] The positioning mechanism 4 also includes a guide rail 45 and a sliding shell 46. The guide rail 45 is respectively disposed on the opposite inner side of the two transverse baffles 41, and the sliding shell 46 is respectively disposed on the front and rear ends of the longitudinal baffle 42. The sliding shell 46 is laterally slidably connected to the adjacent guide rail 45. The relative sliding between the sliding shell 46 and the guide rail 45 provides guiding support for the movement of the longitudinal baffle 42. The surface of the longitudinal baffle 42 is provided with clearance sliding holes that cooperate with the guide rail 45.

[0023] The positioning mechanism 4 also includes a rotating plate 47, an adjusting block 48, and a supporting slide column 49. The adjusting block 48 is vertically slidably connected to the opposite outer sides of the two longitudinal baffles 42. The front and rear ends of the adjusting block 48 are rotatably connected to the rotating plate 47 through a rotating shaft one. The lower end of the rotating plate 47 is rotatably connected to the adjacent limiting insert plate 44 through a rotating shaft two. The supporting slide column 49 is respectively set on the opposite outer sides of the two longitudinal baffles 42. The supporting slide column 49 is slidably connected to the clearance groove in the middle of the rotating plate 47. When the adjusting block 48 moves upward, the adjusting block 48 and the upper end of the rotating plate 47 rotate relative to each other, pulling the upper end of the rotating plate 47 upward. Under the support of the supporting slide column 49, the supporting slide column 49 slides and rotates in the clearance groove of the rotating plate 47, so that the lower end of the rotating plate 47 applies a force to the limiting insert plate 44, pulling the limiting insert plate 44 to move horizontally, which facilitates the simultaneous pulling of the two limiting insert plates 44 corresponding to the longitudinal position to move synchronously.

[0024] Rollers 5 are rotatably connected between the front and rear inner walls of the sliding shell 46 via a rotating shaft. The outer arc surface of the roller 5 is in contact with the surface of the adjacent guide rail 45. The outer arc surface of the lower roller 5 is in contact with the lower surface of the lower guide rail 45, and the upper roller 5 is in contact with the upper surface of the upper guide rail 45. This restricts the vertical position of the longitudinal baffle 42. The relative rotation between the roller 5 and the guide rail 45 reduces the friction force experienced by the longitudinal baffle 42 during its movement.

[0025] Each adjusting block 48 is rotatably connected to an adjusting screw 6 in the middle. The upper end of the adjusting screw 6 is threadedly connected to the support block at the upper end of the longitudinal baffle 42. Rotating the adjusting screw 6 causes the adjusting screw 6 to rotate relative to the adjusting block 48 through the threaded connection between the adjusting screw 6 and the support block of the longitudinal baffle 42, thereby causing the adjusting screw 6 to drive the adjusting block 48 to move upward.

[0026] It also includes a protective cover 7, which is respectively set on the opposite outer sides of the two longitudinal baffles 42. The rotating plate 47 and the adjusting block 48 are respectively located inside the adjacent protective cover 7, which hides the transmission components such as the rotating plate 47 and the adjusting block 48, so as to avoid direct exposure to external dust affecting their normal operation. The limiting plate 44 is longitudinally slidably connected to the clearance hole on the surface of the protective cover 7. The limiting plate 44 always blocks the clearance hole to prevent external dust from entering the interior of the protective cover 7.

[0027] Hook holes 8 are provided at the lower ends of the longitudinal baffle 42 and the transverse baffle 41. For irregular goods, while using the transverse baffle 41 and the longitudinal baffle 42 to enclose them, the hooks at the ends of the straps can be attached to the hook holes 8 to further position the goods using the straps. The hook holes 8 on the surface of the transverse baffle 41 are evenly distributed laterally, and the hook holes 8 on the surface of the longitudinal baffle 42 are evenly distributed longitudinally.

[0028] The working principle of the fixed lifting platform for easy cargo positioning provided by this utility model is as follows: When the cargo is placed on the upper surface of the carrying platform 3, the adjusting screw 6 is rotated. Through the threaded connection between the adjusting screw 6 and the support block of the longitudinal baffle 42, the adjusting screw 6 and the adjusting block 48 rotate relative to each other, causing the adjusting screw 6 to drive the adjusting block 48 to move upward. At this time, the adjusting block 48 and the upper end of the rotating plate 47 rotate relative to each other, pulling the upper end of the rotating plate 47 upward. Under the support of the supporting slide column 49, the supporting slide column 49 slides and rotates in the clearance groove of the rotating plate 47, so that the lower end of the rotating plate 47 applies a force to the limiting insert plate 44, pulling the limiting insert plate 44 to move horizontally, so that the limiting insert plate 44 leaves the limiting slot on the surface of the limiting plate 43, thus canceling the limitation on the longitudinal baffle 42. Estimate the space occupied by the cargo and adjust the left and right positions of the longitudinal baffle 42. After the adjustment is completed, the adjusting screw 6 is rotated in the opposite direction, so that the limiting insert plate 44... 4. Insert the limiting plate 43 into the limiting slot on its surface to restrict the position of the longitudinal baffle 42. Then, place and stack the goods within the space enclosed by the transverse baffle 41 and the longitudinal baffle 42. During the placement process, the left and right positions of the longitudinal baffle 42 can be adjusted according to the actual space occupied by the goods. After placement, for goods in regular boxes or bags, the transverse baffle 41 and the longitudinal baffle 42 can be used to surround the goods and position them horizontally on the surface of the carrying platform 3. For irregular goods, while using the transverse baffle 41 and the longitudinal baffle 42 to surround them, the hooks at the ends of the straps can be connected to the hook holes 8 to further position the goods using the straps. After positioning, the scissor-type support arm 2 is pushed by the electro-hydraulic push rod inside the fixed base 1 to unfold or fold, thereby realizing the lifting and lowering movement of the carrying platform 3 and driving the goods placed on the surface of the carrying platform 3 to rise and fall.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
