Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a heavy-load transfer platform with a zero-gravity lifting guardrail. Background Art

[0002] In the prior art, in order to improve the safety of the loading and transport process, guardrails are installed around the transfer platform to prevent items from tipping over or falling when loading or transporting heavy or tall items. However, the existing guardrails are usually fixed to the platform, and the guardrails are a certain height higher than the surface of the transfer platform. This fixed guardrail causes great inconvenience to the loading and unloading operations of items, especially for heavier items, which require a higher lifting height to be successfully loaded and unloaded. In addition, if the height of the items is low, the space above the guardrail cannot be effectively utilized, resulting in waste. If the height of the items is high, the guardrail cannot provide effective protection. Therefore, for items of different heights and sizes, the protective effect of a guardrail with a fixed height is very limited. In view of this, if the guardrail is set to an automatic lifting type, the cost of installing and maintaining the lifting drive mechanism is high. If the guardrail is set to a manual lifting type, manual driving is time-consuming and labor-intensive, and the operation is inconvenient. Utility Model Content

[0003] In view of the deficiencies of the existing technology, the utility model provides a heavy-load transfer platform with a gravity-free lifting guardrail, aiming to improve the applicability and convenience of protecting objects at different heights.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A heavy-load transfer platform with a zero-gravity lifting guardrail comprises a platform body, a guardrail and a lifting and weight-reducing module;

[0006] The upper surface of the platform body is provided with a bearing surface;

[0007] At least one side surface of the platform body is provided with at least one lifting and weight reduction module;

[0008] The guardrail surrounds at least one side surface of the platform body and is connected to the lifting and weight reduction module on the at least one side surface;

[0009] The guardrail is slidably matched with the lifting and weight-reducing module to be lifted and lowered in a direction perpendicular to the bearing surface;

[0010] The weight of the guardrail is equal to the sum of the weights of the counterweights of all the lifting and weight-reducing modules connected thereto.

[0011] Further technical solutions are:

[0012] The structure of the lifting and weight reduction module includes a mounting frame, in which a linear bearing, a pulley, a connecting rope and the counterweight are arranged;

[0013] The linear bearing and the counterweight are respectively located on the left and right sides of the pulley;

[0014] The movable end of the linear bearing is connected to the guardrail via a connecting piece;

[0034] See also Figures 1 to 3 The heavy-load transfer platform with a zero-gravity lifting guardrail of this embodiment includes a platform body 1, a guardrail 2, and a lifting and weight reduction module;

[0035] The upper surface of the platform body 1 is provided with a carrying surface 101, which is used to place the items 5 to be transferred;

[0036] At least one lifting and weight reduction module is provided on at least one side surface of the platform body 1;

[0037] The guardrail 2 surrounds at least one side surface of the platform body 1 and is connected to the lifting and weight reduction module of the at least one side surface;

[0038] The guardrail 2 is in sliding cooperation with the lifting and weight reduction module, and is lifted and lowered in a direction perpendicular to the bearing surface 101;

[0039] The weight of the guardrail 2 is equal to the sum of the weights of the counterweights 9 of all the lifting and weight-reducing modules connected thereto.

[0040] As a specific embodiment, the structure of the lifting and weight reduction module includes a mounting frame 3, in which a linear bearing 4, a pulley 6, a connecting rope 7 and a counterweight 9 are arranged;

[0041] The linear bearing 4 and the counterweight 9 are respectively located on the left and right sides of the pulley 6;

[0042] The moving end of the linear bearing 4 is connected to the guardrail 2 via a connector 10;

[0043] One end of the connecting rope 7 is connected to the movable end of the linear bearing 4 , and the other end is connected to the counterweight 9 after passing around the pulley 6 .

[0044] The linear bearing 4 includes a guide post 42 as a fixed end and a slider 41 as a movable end. The guide post 42 is vertically arranged, and the slider 41 and the guide post 42 slide together in the vertical direction.

[0045] Specifically, the connecting rope 7 is a steel wire rope.

[0046] Specifically, the mounting frame 3 is fixedly connected to the platform body 1, and end plates are respectively provided at the upper and lower ends of the mounting frame 3; the guide column 42 is arranged between the upper and lower end plates; the counterweight 9 is fixed in the area of ​​the mounting frame 3 close to the lower end plate; the pulley 6 is arranged in the area of ​​the mounting frame 3 close to the upper end plate.

[0047] Specifically, the mounting frame 3 can be enclosed to meet both plot and aesthetic requirements.

[0051] The working principle and usage of the heavy-load transfer platform with zero-gravity lifting guardrail in this embodiment are as follows:

[0052] The guardrail can be raised and lowered, making it suitable for protecting objects of varying heights. The guardrail's weight is equal to the combined weight of the counterweight components of the associated lifting counterweight module. When the guardrail is manually raised or lowered, the counterweight components completely offset its weight. This allows the guardrail to be started and stopped at any height within the linear bearing's travel range with virtually no effort, significantly saving manpower. The guardrail can be conveniently lowered to a low position for loading and unloading, and raised to a high position for protection during transport. This also enhances its suitability for protecting objects of varying heights and sizes. Furthermore, the coordination of the pulley and connecting rope improves the smoothness of the guardrail's raising and lowering process.
