Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting device for molds. Background Technology

[0002] In the mold manufacturing process, multiple processing steps are involved. Lifting equipment can quickly move the mold from one process equipment to the next process equipment, reducing the turnaround time of the mold between processes. Currently, cranes are the most common type of lifting equipment for molds, mainly used for the lifting and transportation of outdoor molds, moving the mold from one work area to another.

[0003] A crane is a lifting device installed on a vehicle. It uses a hydraulic system to control the extension and retraction of the boom and the raising and lowering of the hook to lift molds. Existing mold cranes cannot independently extend and retract each lifting support leg because the usage scenarios are relatively fixed, which makes them unable to adapt to different ground conditions and different working heights. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a lifting device for molds, which aims to improve the problem that the lifting support legs cannot be independently extended and retracted, resulting in an inability to adapt to different ground conditions and different working heights.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for molds, comprising a body, four outer covers on the left and right sides of the body, a first cylinder fixedly connected to the inner top wall of each of the four outer covers, a telescopic cover fixedly connected to the output end of each of the four first cylinders, gears rotatably connected inside each of the four telescopic covers, a second rack meshing with the front side of each of the four gears, the four second racks fixedly connected to the four outer covers, a first rack meshing with the rear side of each of the four gears, a telescopic rod fixedly connected to the rear side of each of the four first racks, the four telescopic rods slidably connected to the four telescopic covers, the four telescopic covers slidably connected to the four outer covers, and a connecting assembly provided on the lower side of the body, the connecting assembly being used to facilitate equipment maintenance and repair, and to adapt to different ground environments when combined with different chassis.

[0006] Preferably, the connecting assembly includes a vehicle body located on the lower side of the fuselage. A handle is provided inside the vehicle body, a limit block is fixedly connected to the rear side of the handle, a locking hook is provided on the upper side of the limit block, a second spring is fixedly connected to the left side of the locking hook, the second spring is fixedly connected to the vehicle body, and a first spring is fixedly connected to the left side of the handle, the first spring is fixedly connected to the vehicle body.

[0007] Preferably, four fixing rods are fixedly connected to the left and right sides of the machine body, and the fixing rods are fixedly connected to the outer cover.

[0008] Preferably, a connecting block is fixedly connected to the top of the front side of the machine body, and a second cylinder is rotatably connected to the top of the connecting block, with the output end of the second cylinder fixedly connected to the lifting arm.

[0009] Preferably, each of the four telescopic rods has a fixed foot rotatably connected to its top, and the fixed foot is a non-slip steel plate.

[0010] Preferably, the lifting arm is rotatably connected to the connecting block, and a hook is provided on the front side of the lifting arm.

[0011] Preferably, a traction pin is fixedly connected to the bottom of the machine body, and the traction pin is T-shaped.

[0012] Preferably, the traction pin is located inside the locking hook, and the locking hook is rotatably connected to the vehicle body.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the first cylinder drives the outer cover to move upward, and the outer cover drives the gear to rotate through the second rack. Due to the restriction of the first rack, the gear will drive the telescopic cover to move upward when rotating, and finally lift the entire equipment, thereby achieving the purpose of adapting to different ground and different working heights, and solving the problem that the crane cannot lift the mold to the required height and work on uneven ground.

[0015] 2. In this utility model, when the handle is pulled, the handle causes the limiting block to move to the right. At this time, the locking hook rotates to the position where the opening faces backward under the action of the second spring. At this time, the traction pin can be moved out of the vehicle body, thereby facilitating the maintenance and repair of the equipment and adapting to different ground environments by combining with different chassis. This solves the problems of the crane being unable to change chassis and the great inconvenience during maintenance. Attached Figure Description

[0027] Specifically, the handle 16 is used to move the limiting block 19, which can lock the hook 20. The second spring 18 is used to give the hook 20 a reaction force so that the hook 20 opens backward when it is not restricted by the limiting block 19. The body 11 is used to fix the second spring 18 and the first spring 17. The first spring 17 is used to reset the handle 16 after it is pulled.

[0028] Reference Figure 1 Four fixing rods 9 are fixedly connected to the left and right sides of the body 10, and the fixing rods 9 are fixedly connected to the outer cover 1.

[0029] Specifically, the body 10 is used to fix the position of the fixing rod 9, and the fixing rod 9 is used to fix the position of the outer cover 1.

[0032] Reference Figure 2 Each of the four telescopic rods 4 has a fixed foot 8 that is rotatably connected to its top. The fixed foot 8 is made of anti-slip steel plate.

[0033] Specifically, the fixed foot 8 is fixed on the working surface to prevent overall instability during operation.

[0034] Reference Figure 1 The boom 12 is rotatably connected to the connecting block 15, and a hook 13 is provided on the front side of the boom 12.

[0035] Specifically, the connecting block 15 is used to control the movement trajectory of the lifting arm 12, and the lifting arm 12 controls the hook 13 to lift the mold.

[0036] Reference Figure 5 A traction pin 21 is fixedly connected to the bottom of the fuselage 10. The traction pin 21 is T-shaped.

[0037] Specifically, the traction pin 21 is used to fix the position of the body 10. The traction pin 21 is T-shaped and can be inserted into the locking hook 20.

[0038] Reference Figure 3 and Figure 4 The traction pin 21 is located inside the locking hook 20, and the locking hook 20 is rotatably connected to the vehicle body 11.

[0039] Specifically, the body 11 is used to control the movement trajectory of the hook 20, and the traction pin 21 connects the body 10 and the body 11 when it is inside the hook 20.

[0040] Working principle: When the lifting support legs are extended and retracted to adapt to different ground conditions and working heights, the first cylinder 2 drives the outer cover 1 to move upward through the reaction force of the telescopic cover 3. The outer cover 1 drives the second rack 6 to move upward, and the second rack 6 drives the gear 7 to rotate. Under the reaction force of the first rack 5, the gear 7 rotates while carrying the telescopic cover 3 upward. At this time, the entire equipment balances the weight and adapts to the working height by raising the support legs, thereby achieving the purpose of adapting to different ground conditions and working heights. This solves the problem that the crane cannot lift the mold to the required height and works on uneven ground. When it is necessary to maintain and repair the equipment or combine it with different chassis to adapt to different ground environments, adjust the height of the support legs so that the body 17 and the machine body 10 are parallel, pull the handle 16, and the handle 16 drives the limit block 19 to move to the right. At this time, the locking hook 20 opens backward under the action of the second spring 18, separating the body 11 and the machine body 10. This achieves the purpose of facilitating the maintenance and repair of the equipment and adapting it to different ground environments by combining it with different chassis. This solves the problem that the crane cannot change chassis and is very inconvenient during maintenance.
