Embodiment 1

[0032] Such as figure 1 , 2 , 3 and 3a, the scissors support device of the present invention includes a pair of scissors support assemblies 11, 12 symmetrically arranged on the base 10, and the left scissors support assembly 11 and the right scissors support assembly 12 pass through the support hinge shaft 9a It is connected with the connecting shaft 9b.

[0033] Wherein, the function of the connecting shaft 9b is to coordinate the synchronization of both sides and ensure the stability of the scissors support device itself. The supporting hinge shaft 9a is the installation and positioning part of the scissors support device and the object to be supported, and the load of the object to be supported is transmitted to the scissors support assembly 11, 12 through the support hinge shaft 9a. The structure of the supporting hinge shaft is a three-section bending shaft, that is, the two ends of the supporting hinge shaft 9a are perpendicular to the first and second upper scissor ar...

Embodiment 2

[0040] Describe the structure of the scissors support device in detail below in conjunction with accompanying drawing. Such as Figure 6 , 6a As shown, the structure of the scissors support device in Embodiment 2 of the present invention includes a pair of scissors support assemblies 11 and 12 arranged symmetrically on the base 10. 9a is connected to connecting shafts 9b, 9c.

[0041] Among them, the function of the connecting shafts 9b, 9c is to coordinate the synchronization of both sides and ensure the stability of the scissors support device itself. The supporting hinge shaft 9a is the installation and positioning part of the scissors support device and the object to be supported, and the load of the object to be supported is transmitted to the scissors support assembly 11, 12 through the support hinge shaft 9a. The structure of the supporting hinge shaft 9a is a three-stage bending shaft, that is, the two ends of the supporting hinge shaft 9a are perpendicular to the fir...

Embodiment 3

[0049] Figure 7 , 8 , 9, 9a show the third embodiment of the scissors brace device of the present invention.

[0050] Such as Figure 9 and 9a As shown, the scissors support device of the present invention includes a pair of scissors support assemblies 11 and 12 symmetrically arranged on the base 10. The left scissors support assembly 11 and the right scissors support assembly 12 are connected by a support hinge shaft 9a and a connecting shaft 9b , 9c is connected.

[0051] Among them, the function of the connecting shafts 9b, 9c is to coordinate the synchronization of both sides and ensure the stability of the scissors support device itself. The supporting hinge shaft 9a is the installation and positioning part of the scissors support device and the object to be supported, and the load of the object to be supported is transmitted to the scissors support assembly 11, 12 through the support hinge shaft 9a. The structure of the supporting hinge shaft 9a is a three-stage be...

Abstract

The invention provides a cross bridging device, which comprises a base (10), at least two pairs of shear arms (1, 2, 3, 4, 21 and 22) and a hydraulic cylinder (5), wherein the shear arms are arrangedfrom top to bottom, are hinged with each other and are arranged on the base (10), and the hydraulic cylinder acts on the at least two pairs of the shear arms so that the shear arms are lifted up to apropping state form the state of horizontal placement on the base. The cross bridging device has strong applicability, occupies a small floor space, can be mounted and positioned quickly, is very convenient to be dismantled quickly by manpower, and not only meets use requirements but also considers harsh place conditions.

Description

technical field [0001] The invention relates to a support device which can be raised and lowered, in particular to a scissors support device used in stage equipment to make the stage go up and down. Background technique [0002] In a large circular stage, it is often necessary to change the height and or shape of the stage in order to meet the needs of the director's creativity. For example, a disc-shaped stage can be composed of multiple fan-shaped modules. Before the performance, the height of the stage should be as high as possible. Lowering, during the performance, the stage is required to be raised and raised, that is, it is slightly spherical, and it must be ensured that in these two states, the stage can be performed or danced by people on the stage. For this kind of stage that is raised from a plane to form a microsphere, the ordinary hydraulic lifting mechanism is difficult to meet the requirements of use. Contents of the invention [0003] The object of the pres...
