Description

Technical Field

[0001] This utility model relates to molds, specifically to a large mold hoisting equipment. Background Technology

[0002] When hoisting large molds, mold factories often use gantry cranes with hooks due to the lack of suitable lifting equipment. Because of the large size and weight of the molds, the center of gravity is difficult to control and adjust, leading to swaying during hoisting and posing significant safety hazards. Therefore, it is necessary to improve upon the shortcomings of existing technology. Utility Model Content

[0003] This application aims to address the problems mentioned in the background section.

[0004] This utility model discloses a large mold hoisting device, comprising:

[0005] A crossbeam, the upper end of which is provided with a hanging lug, which is connected to an external lifting device;

[0006] An adjusting element is installed on the lower end face of the crossbeam;

[0007] A hoisting assembly, comprising multiple hoisting components, wherein multiple hoisting components are arranged along the length direction of the crossbeam;

[0008] The adjusting component is used to adjust the spacing between the multiple lifting components, which together lift the mold.

[0009] The lifting components include a linkage mechanism and a left clamping arm and a right clamping arm located at the execution end of the linkage mechanism. The mold is located within the space enclosed by the left clamping arm and the right clamping arm. This utility model uses multiple lifting components to simultaneously clamp and lift the mold, and the spacing can be adjusted according to the size of the mold using an adjustable component, which can adjust the center of gravity during lifting. This lifting equipment has the advantages of high safety, wide adaptability, and stable lifting.

[0010] In one specific embodiment, the adjusting component includes a motor mounted on the crossbeam and a lead screw rotatably connected to the crossbeam. The lifting component is screwed to the lead screw. The rotation of the lead screw can drive the lifting component to move back and forth along the length direction of the crossbeam. The motor drives the lead screw to rotate, thereby driving the horizontal movement of the lifting component. The structure is simple and the adjustment is convenient.

[0011] In one specific embodiment, the linkage mechanism includes a first link and a second link, which are pivotally connected. The left clamping arm is located at the end of the first link, and the right clamping arm is located at the end of the second link. A connecting block is pivotally connected to the top of the first link and the second link, and the connecting block is screwed to the lead screw. The linkage mechanism uses the weight of the mold itself for movement, and its clamping force can adapt itself, ensuring stability when hoisting molds of different masses. Moreover, no additional power is required for support, resulting in low cost.

[0012] In one specific embodiment, the first connecting rod and the second connecting rod are connected by a shaft. A guide plate is fixed to the side of the connecting block. The guide plate is provided with a U-shaped groove. The shaft can slide in the U-shaped groove. By sliding the shaft in the U-shaped groove, the stability of the linkage mechanism can be improved and deformation of the linkage mechanism can be prevented.

[0013] In one specific embodiment, the inner walls of the first connecting rod and the second connecting rod are respectively pivotally connected to a left pressure arm and a right pressure arm. The left pressure arm and the right pressure arm are pivotally connected, and the ends of the left pressure arm and the right pressure arm have toothed grooves. By pressing the left pressure arm and the right pressure arm with the upper end face of the mold, the stability of the mold hoisting can be improved and it can be prevented from slipping during hoisting.

[0014] Beneficial effects: This utility model uses multiple lifting components to clamp and lift the mold simultaneously, and the spacing can be adjusted according to the size of the mold using adjustable components, which can adjust the center of gravity during lifting. This lifting equipment has the advantages of high safety, wide applicability and stable lifting. Attached Figure Description

The adjusting member 2 is used to adjust the spacing between the multiple hoisting components 3, which together hoist the mold. Each hoisting component 3 includes a linkage mechanism and a left clamping arm 34 and a right clamping arm 3733 located at the execution end of the linkage mechanism. The mold is located within the space enclosed by the left clamping arm 34 and the right clamping arm 3733. This invention uses multiple hoisting components 3 to simultaneously clamp and hoist the mold, and the adjusting member 2 can adjust the spacing according to the size of the mold, thus adjusting the center of gravity during hoisting. This hoisting device has the advantages of high safety, wide adaptability, and stable hoisting.

[0025] See Figure 2 The adjusting component 2 includes a motor 20 installed on the crossbeam 1 and a lead screw 21 rotatably connected to the crossbeam 1. The lifting component 3 is screwed to the lead screw 21. The rotation of the lead screw 21 can drive the lifting component 3 to move back and forth along the length direction of the crossbeam 1. The motor 20 drives the lead screw 21 to rotate, thereby driving the horizontal movement of the lifting component 3. The structure is simple and the adjustment is convenient.

[0026] See Figure 3 The linkage mechanism includes a first link 31 and a second link 32, which are pivotally connected. The left clamping arm 34 is located at the end of the first link 31, and the right clamping arm 3733 is located at the end of the second link 32. A connecting block 30 is pivotally connected to the top of the first link 31 and the second link 32. The connecting block 30 is screwed to the lead screw 21. The linkage mechanism uses the weight of the mold itself for movement, and its clamping force can adapt itself, ensuring stability when hoisting molds of different masses. It does not require additional power for support and has low cost.

[0027] See Figure 4 The first connecting rod 31 and the second connecting rod 32 are connected by a shaft 39. A guide plate 38 is fixed on the side of the connecting block 30. The guide plate 38 is provided with a U-shaped groove 40. The shaft 39 can slide in the U-shaped groove 40. By sliding the shaft 39 in the U-shaped groove 40, the stability of the linkage mechanism can be improved and the deformation of the linkage mechanism can be prevented.
