Description

Technical Field

[0001] The present application relates to the technical field of material handling, and in particular to a pedal-type material lifting frame. Background Art

[0002] Currently, material lifting refers to the process of lifting materials from a low place to a high place. Material lifting is widely used in industrial production, warehousing and logistics and other fields.

[0003] Existing vertical transportation methods such as forklift transportation, elevator transportation, crane transportation, etc., mostly require large-sized transportation equipment that cannot enter small spaces. Therefore, in small warehouses, when transporting materials to shelves, manpower is often relied on.

[0004] The above-mentioned existing technical solutions have the following defects: manual handling often wastes a lot of labor costs and has the problem of high labor intensity for workers. Utility Model Content

[0005] In order to reduce the labor intensity of workers during the process of lifting materials, the present application provides a foot-operated material lifting frame.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A pedal-type material lifting frame includes a base frame abutting a working surface, a driving plate and a lifting structure being provided on the upper surface thereof, one side of the driving plate being rotatably connected to the side of the base frame; the lifting structure includes a sliding rod and a lifting frame, one end of the sliding rod being connected to the base frame, the lifting frame being slidably connected to the sliding rod, and the lifting frame being able to slide up and down along the sliding rod; a linkage structure is also provided between the driving plate and the lifting frame, and the linkage structure is used to drive the lifting frame to slide up and down along the sliding rod when the driving plate rotates along the base frame.

[0008] By adopting the above solution, the driving plate is controlled to rotate around the bottom frame. During the rotation, the driving plate will drive the linkage structure to move. The linkage structure will transmit the driving force to the lifting frame, causing the lifting frame to move along the sliding rod, thereby achieving the purpose of lifting the object placed on the lifting frame and reducing the labor intensity of workers.

[0009] Furthermore, the linkage structure includes an input part, an output part, a balancing part and a linkage rope, the input part is arranged on the side close to the driving plate, the output part is arranged on the side close to the lifting structure, the balancing part is located between the input part and the output part, one end of the linkage rope is fixedly connected to the side of the driving plate away from the rotational connection with the bottom frame, and the other end of the linkage rope passes through the input part, the balancing part and the output part in sequence and is fixedly connected to the lifting frame.

[0010] By adopting the above solution, the driving plate is controlled to rotate around the bottom frame, driving the linkage rope to move. After the linkage rope moves, it passes through the input part, the balance part and the output part in sequence, driving the lifting frame to rise and fall along the sliding rod.

[0011] Furthermore, the input part includes a first input wheel, a second input wheel and a third input wheel; a lifting rod is provided on the side of the bottom frame away from the rotational connection with the driving plate, and one end of the lifting rod is fixedly connected to the bottom frame; a high cross bar and a low cross bar are respectively provided at both ends of the lifting rod, and the high cross bar and the low cross bar are both arranged perpendicular to the lifting rod; the first input wheel and the second input wheel are both arranged on the side wall of the high cross bar away from the output part, the first input wheel is arranged at a position close to the driving plate, and the second input wheel is arranged at a position away from the driving plate; the third input wheel is arranged on the same side as the first input wheel and is fixedly connected to the low cross bar; and the third input wheel is located between the first input wheel and the second input wheel, and the end of the linkage rope away from the driving plate passes through the first input wheel, the third input wheel and the second input wheel in sequence and then enters the balancing part.

[0012] By adopting the above solution, because the high cross bar and the low cross bar are provided, the third input wheel is staggered in height with the first input wheel and the second input wheel; and because the third input wheel is located between the first input wheel and the second input wheel, the end of the linkage rope facing away from the drive plate passes through the first input wheel, the third input wheel and the second input wheel in sequence, thereby achieving the effect of tensioning the linkage rope and preventing the linkage rope from loosening between the first input wheel and the second input wheel.

[0013] Furthermore, the output part includes a support rod, a first output wheel and a second output wheel, the support rod is arranged perpendicular to the sliding rod, and the side wall of the support rod is fixedly connected to the sliding rod; the first output wheel and the second output wheel are both connected to a side close to the input part, and the first output wheel and the second input wheel are arranged collinearly; the first output wheel is arranged at a position away from the driving plate, and the second output wheel is arranged at a position close to the driving plate; after the linkage rope is output through the balancing part, it passes through the first output wheel and the second output wheel in sequence and is fixedly connected to the lifting frame; the position where the linkage rope is connected to the lifting frame corresponds vertically to the second output wheel.

[0014] By adopting the above scheme, the first output wheel is used to introduce the linkage rope of the balancing part into the output part, and the second output vertically corresponds to the position where the linkage rope is connected to the lifting frame, so that the linkage rope between the second output wheel and the lifting frame is in a vertical state, effectively improving the effect of the linkage rope driving the lifting frame sliding rod to move up and down.

[0015] Furthermore, the balancing part includes a first balancing wheel and a second balancing wheel, and the first balancing wheel and the second balancing wheel are both arranged on the side of the bottom frame away from the driving plate. The first balancing wheel vertically corresponds to the second input wheel and is fixedly connected to the side wall of the bottom frame. The second balancing wheel vertically corresponds to the first output wheel and is fixedly connected to the side wall of the bottom frame. The linkage rope is output from the second input wheel and enters the second output wheel after passing through the first balancing wheel and the second balancing wheel in sequence.

[0016] By adopting the above scheme, the first balance wheel and the second input wheel correspond vertically, so that the linkage rope between the second input wheel and the first balance wheel is in a vertical state. This arrangement facilitates the transmission of the tension of the linkage rope to the first balance wheel; the first balance wheel and the second balance wheel correspond horizontally, so that the linkage rope between the first balance wheel and the second balance wheel is in a horizontal state; it is convenient to transmit the force of the first balance wheel to the second balance wheel; the second balance wheel and the first output wheel correspond vertically, so that the linkage rope between the second balance wheel and the first output wheel is in a vertical state, it is convenient to transmit the force of the second balance wheel to the first output wheel; and there is a height difference between the first balance wheel and the second input wheel, and there is a height difference between the second balance wheel and the first output wheel, which achieves the effect of tensioning the linkage rope and preventing the linkage rope from loosening.

[0017] Furthermore, the bottom frame is further provided with a stabilizing rod corresponding to the sliding rod, one end of the stabilizing rod is fixedly connected to the bottom frame, the other end of the stabilizing rod is fixedly connected to the support rod, and the lifting frame is slidably connected to the stabilizing rod.

[0018] By adopting the above solution, the arrangement of the stabilizing rod makes the lifting frame more stable when sliding along the sliding rod.

[0019] Furthermore, a reinforcement rod is provided between the raising rod and the low cross rod. The reinforcement rod is placed at an angle, and both ends of the reinforcement rod are fixedly connected to the raising rod and the low cross rod respectively.

[0020] By adopting the above solution, since the reinforcing rod is provided, a triangle is formed between the raising rod, the low cross bar and the reinforcing rod. According to the stability of the triangle, the connection between the raising rod and the low cross bar and the bottom frame is made more stable.

[0021] Furthermore, an amplifying wheel is provided at one end of the first input wheel close to the driving plate. The amplifying wheel is provided on the same side as the first input wheel. The amplifying wheel is fixedly connected to the side wall of the high cross bar. The position of the amplifying wheel vertically corresponds to the position where the linkage rope is connected to the driving plate.

[0022] By adopting the above solution, because the amplifying wheel is provided, the linkage rope between the amplifying wheel and the position where the linkage rope connects to the driving plate is in a vertical state, which can better transmit the force generated by the driving plate rotating along the bottom frame to the amplifying wheel.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up the lifting frame, the driving plate is controlled to rotate around the bottom frame. During the rotation process, the driving plate drives the linkage structure to move. The linkage structure transmits the driving force to the lifting frame, causing the lifting frame to move along the sliding rod, thereby achieving the purpose of lifting objects placed on the lifting frame and reducing the labor intensity of workers;

[0025] 2. By setting up the lifting rod, a triangle is formed between the lifting rod, the low cross bar and the reinforcement rod. According to the stability of the triangle, the connection between the lifting rod, the low cross bar and the bottom frame is more stable;

[0026] 3. By setting up the amplifying wheel, the linkage rope between the amplifying wheel and the position where the linkage rope connects to the driving plate is in a vertical state, which can better transmit the force generated by the driving plate rotating along the bottom frame to the amplifying wheel.
