Embodiment 1

[0019] Such as figure 1 , is the general structure of the single-arm lifting residual angle spring group device, the residual angle spring group K 1 and K 2 One end of each through the roller device A 1 and A 2 Attached to the fillet spring set fixture B 1 and B 2 and can slide, and the other end is connected to the boom L. The top end of the boom L bears the weight G, and the bottom end is connected to the boom fixing structure C. Complementary spring set K 1 and K 2 The action arms are L 1 and L 2 .

[0020] where K 1 with L 1 The included angle θ is always equal to the included angle between the boom L and the horizontal plane, and K 2 with L 2 The angle between them is always 90°-θ; two complementary angle springs K 1 and K 2 The relationship between the strength of and its action arm satisfies K 1 / K 2 =(L 2 / L 1 ) 2 . When the structure is installed, as long as the above conditions are met, a certain fixed weight G can be balanced at any lifting ang...

Embodiment 2

[0022] Such as figure 2 , is the general structure of the supplementary angle spring group device for lifting the parallel link boom, and the supplementary angle spring group K 1 and K 2 One end of each through the roller device A 1 and A 2 Connecting fillet spring set fixture B 1 and B 2 And can slide, the other end is connected with the boom Dm and Dn respectively, the length of the boom of the parallel link is L, and the heavy object bearing layer E at the top can bear the heavy object G, such as a car or a large cargo with a large volume, so that this The application scope of the invention is wider, the bottom end of the parallel link boom is connected with the boom fixing device C, and the supplementary angle spring group K 1 and K 2 The action arms are L 1 and L 2 .

[0023] where K 1 with L 1 The included angle θ is always equal to the included angle between the boom and the horizontal plane, and K 2 with L 2 The angle between them is always 90°-θ; two com...

Embodiment 3

[0025] Such as image 3 , is a parallel connecting rod double-arm lifting residual angle spring set device and double-layer storage structure, residual angle spring set K 1 and K 2 average level, respectively through the roller device A 1 and A 2 Vertical Fixture C for Attaching Filled Corner Spring Sets 2 up, K 1 and K 2 The other end is connected to the same boom D 1 , parallel link boom D 1 and D 2 The bottom ends of the booms are respectively connected to the boom fixing structure C 1 and C 2 ,D 1 and D 2 The length of each is L, and the top is directly connected to the load-bearing layer E, and at D 2 Install counterweight G' on it. when D 1 and D 2 When in the horizontal position, the counterweight G' can be at D 2 Sliding up, supplementary angle spring set K 1 and K 2 The action arms are L 1 and L 2 , the action arm of the counterweight G' is L'.

[0026] where K 1 with L 1 The included angle θ is always equal to the boom D 1 angle with the horiz...

Abstract

The invention discloses a lifting spring group structure of a power-off suspension arm, which comprises a spring group fixed structure, a suspension arm fixed structure, a roller device, a suspension arm and a complementary angle spring group, and is characterized in that: the complementary angle spring group consists of two springs which are connected with the spring group fixed structure through one end of the roller device respectively, and the other ends of the two springs are connected with the suspension arm through the roller device respectively; and one end of the suspension arm is connected with the suspension arm fixed structure, while the other end bears a weight. In the invention, the gravity of the weight is completely balanced by the complementary angle spring group in a lifting process, an operator can vertically move the weight by overcoming the small friction resistance at pivot and roller positions, and no power and no electric control elements are required, so that the cost is low, the dismantling and movement are convenient, and specially-assigned personnel are not needed for operation.

Description

technical field [0001] The invention relates to a lifting structure without power, in particular to a lifting spring group structure of a powerless boom. Background technique [0002] In scattered and small places, when large-scale lifting equipment with self-powered or electric power cannot be deployed, lifting only by manpower is very limited. Taking the three-dimensional garage as an example, the existing large-scale three-dimensional garage is inseparable from the power supply and electrical control components, which requires a large investment, complicated installation and maintenance, and requires centralized management by a dedicated person, which is inconvenient to remove. The disadvantages of the above-mentioned lifting and storage devices are summarized as follows: (1) They are all composed of power sources and electrical control components, and cannot work without power or power supply; (2) The installation and maintenance are complicated, and the operation requir...
