Description

Technical Field

[0001] This utility model relates to the technical field of metal foil cleaning line equipment, specifically to a metal foil cleaning line conveying trolley. Background Technology

[0002] The metal foil cleaning line's coil transport trolley is used for loading, unloading, and transporting metal foil coils at the beginning or end of the metal foil cleaning line; see the attached instruction manual. Figure 1 The existing metal foil cleaning line's coil transport trolley includes a trolley chassis assembly and lifting bracket assemblies located on the left and right sides of the upper part of the chassis assembly. Each lifting bracket assembly contains a lifting slider for lifting the metal foil coil, driven by a lifting cylinder. To ensure synchronous lifting of the left and right lifting sliders, a lifting synchronization shaft is installed between the left and right lifting bracket assemblies. Lifting synchronization gears are fixed at both ends of the lifting synchronization shaft, meshing with a synchronization rack on the lifting bracket assembly to ensure synchronous lifting of the left and right lifting sliders. However, the presence of the synchronization lifting mechanism between the left and right lifting bracket assemblies in this metal foil cleaning line's coil transport trolley makes its structure overly complex. Furthermore, the presence of the lifting synchronization shaft limits the maximum coil diameter of the metal foil coil within a fixed overall height of the trolley, necessitating frequent coil changes during production and impacting the efficiency of metal foil coil production, transfer, and storage. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model discloses a metal foil cleaning line transport trolley to solve the problems of complex structure, small maximum winding diameter of metal foil rolls, and low efficiency of metal foil roll production, transfer and storage.

[0004] To achieve the aforementioned utility model objective, the present utility model adopts the following technical solution: a trolley for transporting metal foil rolls at the beginning or end of a metal foil cleaning line, used for loading, unloading, and transporting metal foil rolls; comprising a trolley chassis assembly and a lifting platform assembly, the lifting platform assembly being vertically and vertically mounted on the upper part of the trolley chassis assembly; the trolley chassis assembly and the lifting platform assembly are connected by a lifting hydraulic cylinder and guided by four guide pillars and guide sleeves.

[0005] Furthermore, the lifting cylinder is fixedly installed in the lower middle part of the trolley chassis assembly.

[0006] Furthermore, guide columns are fixedly installed at the four corners of the lifting platform assembly, and guide sleeves are fixedly installed on the trolley chassis assembly.

[0007] Preferably, the guide sleeves are fixedly installed at the four corners of the lifting platform assembly, and the guide posts are fixedly installed on the trolley chassis assembly.

[0008] Furthermore, a pair of drum support plates are fixedly installed on the upper part of the chassis assembly of the trolley. The upper part of the drum support plates is provided with a V-shaped groove, and a drum support block is replaced on the V-shaped groove.

[0009] Furthermore, a lifting plunger connecting ear is fixedly installed on the upper part of the lifting platform assembly, and a lifting plunger is movably installed on the lifting cylinder; the lifting plunger connecting ear and the lifting plunger are connected by a pin.

[0010] Furthermore, the lower part of the trolley chassis assembly is equipped with rotatable wheels, which are mounted on tracks; the metal foil washing line trolley moves horizontally along the tracks via the wheels.

[0011] Due to the adoption of the above-described technical solution, this utility model has the following beneficial effects: The metal foil cleaning line transport trolley disclosed in this utility model includes a trolley chassis assembly and a lifting platform assembly. The lifting platform assembly is driven and connected to the trolley chassis assembly through a lifting cylinder fixedly installed in the middle of the lower part of the trolley chassis assembly. Guided by four guide pillars and guide sleeves, it is installed on the upper part of the trolley chassis assembly for vertical lifting. Therefore, the synchronous lifting structure of the existing metal foil cleaning line transport trolley is eliminated. At the same time, under the premise that the overall height of the metal foil cleaning line transport trolley is fixed, the maximum winding diameter of the metal foil roll is maximized. There is no need to frequently change the roll during the production process, thereby improving the production, transfer and storage efficiency of the metal foil roll. Attached Figure Description

[0014] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0015] See the instruction manual appendix Figure 1This is a schematic diagram of the external appearance of a trolley used in an existing metal foil cleaning line. The trolley includes a chassis assembly 1 and a lifting bracket assembly 2. Two sets of lifting bracket assemblies 2 are symmetrically fixed to the upper part of the chassis assembly 1. Each lifting bracket assembly 2 includes a lifting slider bracket 2.1, a lifting slider 2.2, and a lifting cylinder 2.3. The lifting slider 2.2 slides vertically inside the lifting slider bracket 2.1. The lifting cylinder 2.3 is fixedly mounted on the upper part of the chassis assembly 1. The top of the plunger of the lifting cylinder 2.3 is fixedly connected to the bottom of the lifting slider 2.2. A synchronous rack 2.4 is fixedly mounted on the side wall of the lifting slider 2.2. When hydraulic oil is injected into the lifting cylinder 2.3, the plunger moves upward, driving the lifting slider 2.2 upward. When the hydraulic oil is released from the lifting cylinder 2.3, the lifting slider 2.2 drives the plunger downward under gravity. A lifting synchronous shaft 3 is rotatably mounted between the left and right lifting bracket assemblies 2. Lifting synchronous shafts 3 are fixedly mounted at both ends. Synchronous gear 3.1, lifting synchronous gear 3.1 meshes with synchronous rack 2.4; when the left and right lifting slider brackets 2.1 move up and down, the synchronous racks 2.4 on both sides drive the lifting synchronous gears 3.1 at both ends of the lifting synchronous shaft 3 to rotate, thereby ensuring the synchronous up and down movement of the left and right lifting slider brackets 2.1 through the lifting synchronous shaft 3; the synchronous up and down movement of the left and right lifting slider brackets 2.1 prevents the roll 5 set on the lifting slider brackets 2.1 from tilting; however, the existing metal foil cleaning line winding trolley has the following problems: because the synchronous lifting structure is set between the left and right lifting bracket components 2, the structure of the metal foil cleaning line winding trolley is too complicated. At the same time, due to the presence of the lifting synchronous shaft 3 between the left and right lifting bracket components 2, under the premise that the overall height of the metal foil cleaning line winding trolley is fixed, the maximum winding diameter of the metal foil roll is limited. Therefore, the roll 5 needs to be changed frequently during the production process, which affects the production, transfer and storage efficiency of the metal foil roll.

[0016] See the instruction manual appendix Figure 2 , 3 The present invention discloses a trolley structure for a metal foil cleaning line, comprising a trolley chassis assembly 1 and a lifting platform assembly 4; wheels 1.2 are rotatably mounted on the lower part of the trolley chassis assembly 1, and the wheels 1.2 are mounted on a track, allowing the metal foil cleaning line trolley to move horizontally along the track via the wheels 1.2; a clearance ditch is provided on the ground between the two tracks. See the instruction manual appendix Figure 4 , 5The car chassis assembly 1 includes a car chassis 1.1, wheels 1.2, guide sleeves 1.4, and lifting cylinders 2.3. The wheels 1.2 are rotatably mounted on the left and right sides of the car chassis 1.1. The guide sleeves 1.4 are fixedly mounted on the left and right sides of the car chassis 1.1 near the wheels 1.2. The lifting cylinders 2.3 are fixedly mounted in the middle of the lower part of the car chassis 1.1. The lifting plunger 2.3.1 of the lifting cylinders 2.3 passes through the car chassis 1.1 and extends to the upper part of the car chassis 1.1. See the instruction manual appendix Figure 6 The lifting platform assembly 4 includes a lifting platform chassis 4.1, a drum support plate 4.2, guide columns 4.3, guide column fixing rings 4.4, and guide column retaining rings 4.5. The drum support plate 4.2 is fixedly installed on the upper left and right sides of the lifting platform chassis 4.1. The upper end of the drum support plate 4.2 is provided with a V-shaped groove, on which a drum support block 4.2.1 is replaceable. When the drum support block 4.2.1 wears out after long-term use, it can be replaced. The guide column fixing rings 4.4... The guide posts 4.3 are fixedly installed at the four corners of the lifting platform chassis 4.1. They are inserted into the guide post fixing rings 4.4. The guide posts 4.3 have a slot 4.3.1 near the upper end. The guide post retaining ring 4.5 is semi-circular and is locked in the slot 4.3.1 at the upper end of the guide post 4.3, and is fixedly connected to the guide post fixing ring 4.4, thereby fixing the guide posts 4.3 to the lifting platform chassis 4.1. The lifting plunger connecting lug 4.1.1 is fixedly installed in the upper middle part of the lifting platform chassis 4.1. The lifting platform assembly 4 is mounted on the upper part of the trolley chassis assembly 1. The lifting plunger 2.3.1 of the lifting cylinder 2.3 passes through the lifting platform chassis 4.1 and is connected to the lifting plunger connecting ear 4.1.1 by a pin. Four guide pins 4.3 are inserted into the guide sleeve 1.4 to provide guidance. When hydraulic oil is injected into the lifting cylinder 2.3, the lifting plunger 2.3.1 moves upward, driving the entire lifting platform assembly 4 to move upward. When the hydraulic oil is released from the lifting cylinder 2.3, the lifting platform assembly 4 drives the lifting plunger 2.3.1 to move downward under the action of gravity. Since the lifting platform assembly 4 has guide pins 4.3 at each of its four corners that cooperate with the guide sleeve 1.4 for guidance, it is ensured that the lifting platform assembly 4 will not tilt during the lifting movement. In this embodiment, the avoidance trench set on the ground between the two tracks prevents the lifting cylinder 2.3 and guide column 4.3 from interfering with the ground.

[0017] In another specific embodiment of this utility model, the guide sleeve 1.4 is fixedly installed at the four corners of the lifting platform assembly 4, and the guide post 4.3 is fixedly installed on the trolley chassis assembly 1. When the guide sleeve 1.4 and the guide post 4.3 are set in this way, the guide post 4.3 will not interfere with the ground, so the width of the clearance groove between the two tracks can be reduced.

[0018] The parts of this utility model not described in detail are existing technologies.
