Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a movable lifting operating platform. Background Technology

[0002] The management of edible mushroom cultivation is extremely difficult to mechanize, and is entirely manual. The mushroom cultivation racks are high-rise, three-dimensional structures, requiring work at height, necessitating the use of ladders. The structure of a ladder can be referenced in Chinese utility model patent application number CN201220715547.6, entitled "Mountainous Ladder." However, using ladders requires frequent climbing to and from workstations, resulting in high labor intensity. If the ladder is too large, movement is inconvenient; if it is too small, the support surface is limited, leading to poor stability. Furthermore, existing ladders lack auxiliary functions, requiring manual passing of materials or tools for work at height. Due to the ineffective use of ladders, workers often climb the mushroom racks directly for work at height to save time, which is not only labor-intensive and inefficient but also poses significant safety hazards and could even lead to accidents. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a manpower-saving, safe and reliable mobile lifting operation platform.

A material frame support rod is installed on the double-pitch chain.

[0006] Furthermore, the number of teeth on both the driving and driven double-pitch sprockets of the two sets of sprocket lifting assemblies is equal.

[0007] Furthermore, the double-pitch chains of the two sets of sprocket lifting assemblies rotate in opposite directions.

[0008] Furthermore, the drive assembly includes a brushless DC motor, a reducer, and a gear chain drive assembly. The brushless DC motor is connected to the reducer, and the reducer is connected to the drive double-pitch sprocket via the gear chain drive assembly.

[0009] Furthermore, a photoelectric switch is provided on one side of the driven double-pitch sprocket on the moving frame, and the photoelectric switch is connected to the DC brushless motor.

[0010] Furthermore, the moving frame is equipped with a material feeding roller assembly located between the active double-pitch sprockets of the two sets of sprocket lifting assemblies.

[0011] Furthermore, the mobile frame is equipped with retractable guardrails around the personnel support platform.

[0012] Furthermore, the folding ladder includes an electric push rod, a ladder, and a two-fold support rod. The ladder is hinged to the moving frame, and the two ends of the electric push rod are respectively hinged to the moving frame and the ladder.

[0025] Please refer to Figures 1 to 5 The present invention provides a movable lifting operation platform, including a movable frame, a lifting mechanism 2, a moving mechanism 3 and a folding mechanism 4; the movable frame includes a main frame 1;

[0026] The lifting mechanism 2 is installed inside the main frame 1 and is used to transport materials;

[0027] The moving mechanism 3 is installed within the main frame 1 and is used to provide movement and steering;

[0028] The folding mechanism 4 is installed on the main frame 1 to facilitate personnel getting on and off, expand the support area, and reduce the overall size;

[0029] When in use, untie the casters at the bottom of the ladder 42, start the electric push rod 41 to move forward, thereby pushing the ladder 42 to unfold outward. Once in place, the two-fold support rod 43 acts as a limit.

[0030] The operator climbs up the ladder 42 to the personnel support platform 11, pulls up the telescopic handle 33, and after it is in place, the limit plunger 36 automatically locks in position. Then the handle 32 is extended, and after it is in place, the handle plunger 35 automatically locks in position.

[0031] The active double-pitch sprocket includes double-pitch sprocket 29, double-pitch sprocket 211, double-pitch sprocket 214 and double-pitch sprocket 215;

[0032] The double-pitch chain includes double-pitch chain 213, double-pitch chain 216, double-pitch chain 210 and double-pitch chain 212;

[0033] The driven double-pitch sprockets include double-pitch sprocket 219, double-pitch sprocket 220, double-pitch sprocket 222 and double-pitch sprocket 223;

[0034] The gear and chain drive assembly includes a power sprocket 23, a chain 24, a sprocket 25, a sprocket 26, a first gear 27, and a second gear 28;

[0035] The material frame support rod includes a first support plate 217 and a second support plate 218;

[0036] The DC brushless motor 21 is started, and power is transmitted to the power sprocket 23 through the first reducer 22, driving the chain 24 to move. This, in turn, drives the sprockets 25 and 26 connected to the sprocket. The sprocket 26 drives the coaxial first gear 27 to move, and the first gear 27 drives the meshing second gear 28 to move, ultimately transmitting the motor's power to the left and right sides respectively. Sprocket 25 drives the coaxial double-pitch sprockets 214 and 215 to move synchronously, and the first gear 27 drives the coaxial double-pitch sprockets 29 and 211 to move synchronously. The double-pitch sprockets 214 and 215 drive the double-pitch chains 213 and 216 to move, and the double-pitch sprockets 29 and 211 drive the double-pitch chains 210 and 212 to move. The double-pitch chains 213 and 215 drive the second support plate 218 to move upward, and the double-pitch chains 210 and 212 drive the second support plate 218 to move.

[0037] Since the drive sprockets 23, 25, and 26 have the same number of teeth and are connected by a chain, their movement speeds are the same. Similarly, since the meshing first gear 27 and second gear 28 have the same number of teeth, their movement speeds are also the same. Therefore, the movement speeds of sprockets 25 and 28 are the same, ultimately achieving the same movement speed on both the left and right shafts.

[0038] The framed material is placed on the material feeding roller assembly 12. The second support plate 218 conveys the framed material from bottom to top. When the framed material reaches the designated position, the photoelectric switch 221 senses the frame, and the DC brushless motor 21 stops, thus stopping the framed material at the designated position, which the operator can then remove. When the photoelectric switch 221 no longer detects a frame, the DC brushless motor 21 starts, and the support plate lifts the next frame of material until the photoelectric switch 221 senses a frame, thereby achieving continuous upward lifting motion of the framed material.

[0039] After the platform is assembled, the operator turns handle 31 to transmit a signal to the mobile motor 311. The power passes through the second reducer and differential 312 and is finally transmitted to the wheels 313, enabling the platform to move forward as a whole. The operator turns handle 31 left and right to move handle 32, telescopic handle 33, limit handle 34 and first drive shaft 37 left and right. The left and right movement of the first drive shaft 37 drives the second drive shaft 38 to move back and forth. The back and forth movement of the second drive shaft 38 drives the steering shaft 39 to rotate left and right, thereby driving the chassis 310 connected to the steering shaft 39 to move left and right, and finally enabling the wheels 313 to turn left and right.

[0040] After all the work of mounting the ladder is completed, the operator retracts handle 32 downwards, then retracts telescopic handle 33 downwards, and steps down ladder 42. The electric actuator 41 is then activated to retract ladder 42, and the casters at the bottom of ladder 42 are locked.

[0041] The frame is equipped with a limit plate 225;

[0042] In this embodiment, the main frame also includes a telescopic guardrail 13. When in use, the telescopic guardrail 13 is raised and then inserted into a pin to fix the position. When not in use, the pin is pulled out and the telescopic guardrail 13 is lowered to reduce the overall height of the operating platform.

[0043] In this embodiment, the lifting mechanism 2 also includes a guiding device, which includes a guide column 226 and a guide support plate 227. The guide column 226 is fixed on the guide support plate 227, and the guide support plate 227 is fixed on the main frame 1.

[0044] In this embodiment, the lifting mechanism 2 also includes an adjusting component sliding bearing seat 224. In use, the nut on the sliding bearing seat is rotated, and the adjusting block moves forward or backward, thereby adjusting the up and down position of the shaft, and finally adjusting the tension of the chain to meet the requirements.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
