Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, and specifically to a lifting device for wheel hub molds. Background Technology

[0002] Automotive wheel hub molds are mainly used to produce aluminum alloy wheels. The main processes include casting, forging, and spin casting. The main types and characteristics are as follows: 1. Low-pressure casting molds: These use a low-pressure process (20-60 kPa) for filling, where the molten aluminum solidifies under pressure. This results in a high yield rate and high production efficiency, suitable for mass production. 2. Gravity casting molds: These rely on the gravity of the molten aluminum for filling and are mostly used for small-sized wheel hub production. Due to their heavy weight, existing wheel hub molds are difficult to handle manually, often requiring the use of lifting equipment.

[0003] Existing hoisting equipment typically uses wire ropes to lift wheel hub molds. After the wheel hub mold is installed, the mold is lifted by winding the wire rope. For example, the wheel hub hook device of the large tire wheel hub hoisting and dismantling machine with publication number CN213326428U controls the upward movement of the hoisted object by controlling the winding of the wire rope. However, during the upward movement of the hoisted object, because the wire rope is long, the hoisted object is easily affected by external factors and sways along with the wire rope, which poses a certain danger. Furthermore, the hoisted object is prone to being hit and damaged during the swaying process. Summary of the Invention

[0008] The mounting base is rotatably connected to a rotating shaft at its rear side; the rear sprockets of the two transmission mechanisms are respectively mounted on both ends of the rotating shaft; the driving mechanism includes a first transmission sprocket, a second transmission sprocket, a second transmission chain, and a second motor; the first transmission sprocket is mounted in the middle of the rotating shaft, and the second transmission sprocket is mounted on the rotating shaft of the second motor; the second transmission chain is mounted on the first transmission sprocket and the second transmission sprocket.

[0009] A mounting bracket is connected above the base; the pushing mechanism includes two sets of symmetrically arranged lifting components; each lifting component consists of multiple sets of vertically arranged scissor lift components; each scissor lift component consists of two inner and outer support rods connected in an X-shape; the middle of the outer support rod is hinged to the middle of the inner support rod; in two adjacent scissor lift components, the lower end of the inner support rod of the upper scissor lift component is hinged to the upper end of the outer support rod of the lower scissor lift component, and the lower end of the outer support rod of the upper scissor lift component is hinged to the upper end of the inner support rod of the lower scissor lift component; the uppermost scissor lift component... On the assembly, the upper ends of both the inner and outer support rods are connected to upper sliders; the upper sliders are all longitudinally slidably connected to the mounting base; on the scissor lift assembly located at the bottom of the two lifting assemblies, the lower ends of the inner support rods of the two scissor lift assemblies are hinged to the same first mounting panel, and the lower ends of the outer support rods of the two scissor lift assemblies are hinged to the same second mounting panel; the first mounting panel and the second mounting panel are both longitudinally slidably connected to the mounting frame, and the mounting frame is also connected to a control mechanism for controlling the reverse movement of the first mounting panel and the second mounting panel.

[0010] The mounting bracket is equipped with two longitudinal slide rails; both the first mounting panel and the second mounting panel are slidably connected to the two longitudinal slide rails.

[0011] The control mechanism includes a third motor and a control connecting rod connected to the third motor; the control connecting rod is rotatably connected to the mounting bracket, and a first threaded section is provided on the front side of the control connecting rod and a second threaded section is provided on the rear side; the first threaded section and the second threaded section rotate in opposite directions, and a first mounting panel and a second mounting panel are respectively threaded onto the first threaded section and the second threaded section.

[0016] The technical effects that this invention can achieve are:

[0017] 1. In this invention, the hub mold is connected by a hook. During lifting, the second motor is turned on to control the rotation of the two transmission chains, thereby moving the fixed panel and the hub mold upward along the lifting section. At this time, the hub mold is lifted. The present invention adopts a double transmission chain structure to lift the hub mold, which is more stable.

[0018] 2. This invention can not only lift the wheel hub mold with a double transmission chain, but also lift the wheel hub mold higher by pushing the mounting base upward with a pushing mechanism;

[0019] 3. During the use of the pushing mechanism, the present invention controls the rotation of the connecting rod through the third motor, thereby causing the first mounting panel and the second mounting panel to move in opposite directions, thus pushing the mounting base up or down. Since the longitudinal control screw and the second threaded section rotate in opposite directions, when the mounting base is pushed up, the longitudinal control screw controls the fixed frame and the counterweight to move backward, causing the center of gravity of the present invention to move backward, making its overall structure more stable and less likely to tip forward due to the heavy object on the front side (i.e., the wheel hub mold). When the mounting base is pushed down, the fixed frame and the counterweight move forward and are stored under the mounting frame, reducing the floor space. Attached Figure Description

[0029] The invention will now be described in further detail with reference to the accompanying drawings.

[0030] See Figures 1 to 8 .

[0031] A hoisting device for a wheel hub mold includes a base 1, with a mounting seat 2 vertically slidably connected above the base 1. Specifically, a vertical guide rod 71 is connected below the mounting seat 2, and a vertical sleeve 72 matching the vertical guide rod 71 is connected above the base 1. The vertical guide rod 71 is vertically slidably connected within the vertical sleeve 72. The mounting seat 2 is vertically slidably connected to the base 1 through the cooperation of the vertical guide rod 71 and the vertical sleeve 72.

[0032] A pushing mechanism is installed on the base 1 to push the mounting base 2 vertically, and the pushing mechanism can control the up and down movement of the mounting base 2; specifically, a mounting frame 41 is connected above the base 1, and the pushing mechanism includes two sets of lifting components arranged symmetrically on the left and right; the lifting components are composed of multiple sets of vertically arranged scissor assemblies, preferably three sets of vertically arranged scissor assemblies; the scissor assembly is composed of two inner support rods 31 and outer support rods 32 connected in an X shape, and the middle of the outer support rod 32 is hinged to the middle of the inner support rod 31; adjacent scissor assemblies In the middle, the lower end of the inner support rod 31 of the upper scissor lift assembly is hinged to the upper end of the outer support rod 32 of the lower scissor lift assembly, and the lower end of the outer support rod 32 of the upper scissor lift assembly is hinged to the upper end of the inner support rod 31 of the lower scissor lift assembly; on the uppermost scissor lift assembly, both the upper ends of the inner support rod 31 and the upper ends of the outer support rod 32 are connected to upper sliders 33; the upper sliders 33 are all longitudinally slidably connected to the mounting base 2; on the lowermost scissor lift assembly of the two lifting assemblies, the lower ends of the inner support rods 31 of both scissor lift assemblies are hinged to the same first mounting panel 34 (reference). Figure 6The lower ends of the outer support rods 32 of the two scissor lift assemblies are hinged to the same second mounting panel 35. The first mounting panel 34 and the second mounting panel 35 are both longitudinally slidably connected to the mounting frame 41, and the mounting frame 41 is also connected to a control mechanism for controlling the reverse movement of the first mounting panel 34 and the second mounting panel 35. Specifically, the mounting frame 41 is equipped with two longitudinal slide rails 44, and the first mounting panel 34 and the second mounting panel 35 are slidably connected to the two longitudinal slide rails 44. The present invention controls the reverse movement of the first mounting panel 34 and the second mounting panel 35 through the control mechanism, thereby pushing the mounting base 2 to move up or down. Specifically, when the control mechanism controls the distance between the first mounting panel 34 and the second mounting panel 35 to decrease, the mounting base 2 is pushed up; conversely, when the control mechanism controls the distance between the first mounting panel 34 and the second mounting panel 35 to increase, the mounting base 2 is pushed down.

[0033] In terms of the specific structure of the control mechanism, the control mechanism includes a third motor 51 and a control connecting rod 52 connected to the third motor 51; the control connecting rod 52 is rotatably connected to the mounting bracket 41, and the front side of the control connecting rod 52 is provided with a first threaded section 42, and the rear side is provided with a second threaded section 43. The first threaded section 42 and the second threaded section 43 rotate in opposite directions. The first mounting panel 34 and the second mounting panel 35 are respectively threadedly connected to the first threaded section 42 and the second threaded section 43. Through the design of the first mounting panel 34 and the second mounting panel 35 being threadedly connected to the first threaded section 42 and the second threaded section 43, when the third motor 51 controls the control connecting rod 52 to rotate, the first threaded section 42 and the second threaded section 43 respectively drive the first mounting panel 34 and the second mounting panel 35 to move in opposite directions.

[0034] Furthermore, the present invention also includes a counterweight 54. Specifically, a fixed frame 55 is longitudinally slidably connected to the base 1, and the counterweight 54 is installed above the fixed frame 55. More specifically, four longitudinal sliding rods 53 are connected to the base 1, and the fixed frame 55 is longitudinally slidably connected to the four longitudinal sliding rods 53. A first drive sprocket 61 is connected to the middle of the control connecting rod 52, and a longitudinal control screw 62 is rotatably connected to the base 1. A second drive sprocket 63 is connected to the longitudinal control screw 62. The first drive sprocket 61 and the second drive sprocket 63 are connected by a third transmission chain 64. The longitudinal control screw 62 rotates in the opposite direction to the second threaded section 43. The present invention uses a longitudinal control screw... The rod 62 and the second threaded section 43 are designed with opposite rotation directions. While the third motor 51 controls the rotation of the connecting rod 52, the third transmission chain 64 drives the longitudinal control screw 62 and the second drive sprocket 63 to rotate in the same direction. Therefore, when the distance between the first mounting panel 34 and the second mounting panel 35 controlled by the third motor 51 decreases, due to the opposite rotation directions of the longitudinal control screw 62 and the second threaded section 43, the fixed frame 55 and the counterweight 54 move backward, and the center of gravity of the invention moves backward. Conversely, when the distance between the first mounting panel 34 and the second mounting panel 35 controlled by the third motor 51 increases, the fixed frame 55 and the counterweight 54 move forward (see reference). Figure 7 , 8 When the mounting base 2 is pushed upward, the fixed frame 55 and the counterweight 54 move backward; when the mounting base 2 is pushed downward, the fixed frame 55 and the counterweight 54 move forward.

[0035] Both sides of the base 1 are connected to a transmission mechanism, which is symmetrically arranged. A first transmission chain 3 is rotatably connected to each transmission mechanism. The front side of the first transmission chain 3 is a lifting section 4 that slopes upward from back to front. Specifically, the transmission mechanism includes a rear sprocket 11, a lower sprocket 12, an upper sprocket 13, and a middle guide sprocket 14. The rear sprocket 11 is rotatably connected to the rear side of the mounting base 2, the lower sprocket 12 is rotatably connected to the lower front side of the mounting base 2, the upper sprocket 13 is rotatably connected to the upper front side of the mounting base 2, and the middle guide sprocket 14 is rotatably connected to the middle of the mounting base 2. The first transmission chain 3 is rotatably connected to the rear sprocket 11, the lower sprocket 12, the upper sprocket 13, and the middle guide sprocket 14. The lifting section 4 is located between the lower sprocket 12 and the upper sprocket 13.

[0036] Above the mounting base 2 is a drive mechanism for driving the first transmission chains 3 on the two transmission mechanisms to rotate synchronously at the same speed. Specifically, a rotating shaft 21 is rotatably connected to the rear side of the mounting base 2. The rear sprockets 11 of the two transmission mechanisms are respectively installed at both ends of the rotating shaft 21. The drive mechanism includes a first transmission sprocket 22, a second transmission sprocket 23, a second transmission chain 24, and a second motor 25. The first transmission sprocket 22 is installed in the middle of the rotating shaft 21, the second transmission sprocket 23 is installed on the rotating shaft of the second motor 25, and the second transmission chain 24 is installed on the first transmission sprocket 22 and the second transmission sprocket 23. In this invention, the second motor 25 drives the rotating shaft 21 to rotate, thereby driving the rear sprockets 11 on the two transmission mechanisms to rotate synchronously at the same speed, ensuring that the first transmission chains 3 on the two transmission mechanisms rotate synchronously at the same speed.

[0037] A fixed panel 5 is installed between the lifting sections 4 of the two transmission mechanisms. A first motor 6 is installed on the rear side of the fixed panel 5. A winding roller 7 is connected to the shaft of the first motor 6. A pull rope 8 is wound on the winding roller 7. The end of the pull rope 8 passes through the fixed panel 5 and is connected to a hook 9.

[0038] In use, the wheel hub mold is first hooked by the hook 9. Then, the second motor 25 is turned on to drive the first transmission chain 3 on the two transmission mechanisms to rotate synchronously at the same speed, thereby lifting the wheel hub mold. Since the lifting section 4 has a limited upward height, when the lifting height is insufficient, the third motor 51 is turned on. The third motor 51 controls the distance between the first mounting panel 34 and the second mounting panel 35 to decrease, causing the pushing mechanism to push the mounting base 2 upward, thus lifting the wheel hub mold as well, increasing the lifting height of the wheel hub mold. During the process of decreasing the distance between the first mounting panel 34 and the second mounting panel 35, because the longitudinal control screw 62 and the second threaded section 43 rotate in opposite directions, the fixed frame 55 and the counterweight 54 move backward, causing the overall center of gravity of the lifting equipment to shift backward, ensuring that the wheel hub mold is not easily tilted forward during lifting (while when the pushing mechanism moves the mounting base 2 downward, the fixed frame 55 and the counterweight 54 move forward, see reference). Figure 1 , 7 8. By storing the fixed frame 55 and the counterweight 54 under the mounting frame 41, the floor space is reduced; when the wheel hub mold reaches the required height, the first motor 6 is turned on, and the first motor 6 controls the winding roller 7 to rotate, thereby slowly releasing the rope 8, and the hook 9 and wheel hub mold are slowly lowered; the present invention uses double first transmission chains 3 to lift the wheel hub mold, which is relatively stable.
