Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly to an auxiliary reinforcement device for a stage elevator. Background Art

[0002] A stage elevator is a device specifically installed on a stage for stage lifting and rotation, etc., and is one of the most widely used devices in professional opera houses, dance theaters, and dramas. In many internationally renowned concert halls, there are lifting platforms for the orchestra, chorus, or large musical instruments. In some experimental small theaters, in order to achieve changes in the stage form, the entire stage is filled with lifting platforms designed according to modularity. However, the existing stage elevators are prone to accidents due to less support under the platform and low stability. In addition, once the steel wire rope breaks, the platform will immediately fall off, resulting in safety accidents. And if the platform load is overweight, it is very easy to shake, thus causing the lifting platform to tilt and resulting in safety accidents.

[0003] Therefore, there is an urgent need to develop an auxiliary reinforcement device for a stage elevator that can support and reinforce the stage elevator. Summary of the Invention

[0004] In order to overcome the shortcomings that the existing stage elevators are prone to accidents due to less support under the platform and low stability; once the steel wire rope breaks, the platform will immediately fall off; and when the load is overweight, it is easy to shake, resulting in the tilt of the lifting platform, the purpose of the present invention is to provide an auxiliary reinforcement device for a stage elevator that can support and reinforce the stage elevator.

[0005] The technical solution is: an auxiliary reinforcement device for a stage elevator, including a stage elevator, a support mechanism, and a buffer mechanism. The stage elevator is integrally three - layer. A support mechanism for supporting and fixing the elevator is provided on the stage elevator, and a buffer mechanism for preventing the stage elevator from falling rapidly in case of danger is provided on the stage elevator.

[0006] As a further preferred solution, the support mechanism includes a cylinder, a lifting rod, a first pressure spring, and a cross - bar. The cylinder is located at the center position of the bottom of the stage elevator. The lifting rods are connected around the cylinder. A cross - bar is connected to the piston rod of the cylinder. First pressure springs are connected between the lifting rods and the cross - bar, and the first pressure springs are sleeved on the lifting rods.

[0007] As a further preferred solution, the buffer mechanism includes a support rod, a pin, and a connecting block. A support rod is connected to the piston rod of the cylinder. A connecting block is connected to the top of the stage elevator. The connecting block is connected to the support rod. A pin is slidably connected to the upper part of the support rod, and the pin is slidably connected to the left side of the stage elevator.

[0008] As a further preferred solution, it further includes a pulling mechanism for stretching the stage lift. The pulling mechanism includes a connecting rod, a first rotating shaft, a fixing plate, a torsion spring, a second rotating shaft, a rope and a slider. A fixing plate is fixedly connected to the front end of the bottom layer of the stage lift. A second rotating shaft is rotatably connected between the fixing plates. Torsion springs are connected between the left and right sides of the second rotating shaft and the fixing plates respectively. The torsion springs are sleeved on the second rotating shaft. A first rotating shaft is connected to the left side of the second rotating shaft. A slider is slidably connected to the front end of the bottom layer of the stage lift. The slider is used to fix the first rotating shaft. A rope is wound around the second rotating shaft. Connecting rods are connected to the periphery of the top layer of the stage lift. The upper end of the rope is connected to the connecting rod.

[0009] As a further preferred solution, a positioning hole is provided on the slider for clamping the first rotating shaft.

[0010] As a further preferred solution, it further includes an anti-tilting mechanism for supporting and fixing the stage lift. The anti-tilting mechanism includes a connecting rod, a telescopic rod and a second pressure spring. Telescopic rods are connected to the bottom layer of the stage lift. Second pressure springs are sleeved on the telescopic rods. The two ends of the second pressure spring are respectively connected to the telescopic rod and the second layer of the stage lift. Connecting rods are connected between adjacent telescopic rods.

[0011] Beneficial effects: 1. In the present invention, the cylinder can cooperate with the telescopic rod to make the stage lift operate. At the same time, the setting of the clamping pin can fix the top layer of the stage lift to prevent the top layer of the stage lift from sliding and causing safety accidents, so as to be able to support and reinforce the stage lift; 2. In the present invention, the stage lift can be controlled to rise and fall by hand cranking, providing flexibility for the use of the stage lift; 3. The anti-tilting mechanism provided in the present invention is arranged at the bottom layer of the stage lift, which can not only well reinforce the stage lift, but also increase the supporting force of the stage lift, improve the stability, and thus reduce the occurrence probability of stage safety accidents.

Detailed implementation manners

[0021] The embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0022] Embodiment 1: An auxiliary reinforcement device for a stage lift, as Figures 1-4 shown, comprising a stage lift 1, a support mechanism 2 and a buffer mechanism 3. The stage lift 1 is a three-layer structure as a whole. The support mechanism 2 is provided on the stage lift 1, and the support mechanism 2 is used for supporting and fixing the lift. The buffer mechanism 3 is provided on the stage lift 1, and the buffer mechanism 3 is used to prevent the stage lift 1 from falling rapidly in case of danger.

[0023] As Figures 1-4 shown, the support mechanism 2 includes a cylinder 21, a lifting rod 22, a first compression spring 23 and a cross bar 24. The cylinder 21 is provided at the center position of the bottom of the stage lift 1. Four lifting rods 22 are connected around the cylinder 21. Four cross bars 24 are connected to the piston rod of the cylinder 21. The first compression spring 23 is sleeved on the lifting rod 22, and the first compression spring 23 is connected between the lifting rod 22 and the cross bar 24.

[0024] As Figure 4 shown, the buffer mechanism 3 includes a support rod 31, a pin 32 and a connecting block 33. The support rod 31 is connected to the piston rod of the cylinder 21. The upper part of the support rod 31 is slidably connected with the pin 32. The stage pin 32 is slidably connected with the left side of the lift 1. The connecting block 33 is connected to the top of the stage lift 1, and the connecting block 33 is connected to the support rod 31.

[0025] During use, the cylinder 21 is activated. When the piston rod of the cylinder 21 extends or contracts, it drives the second layer of the stage lift 1 to rise or fall. The cross bar 24 connected to the piston rod of the cylinder 21 moves together with the piston rod, playing a role in supporting the stage lift 1 and preventing the stage lift 1 from tilting. A lifting rod 22 is connected below the cross bar 24. The lifting rod 22 plays a role in supporting the cross bar 24. At the same time, the first pressure spring 23 sleeved on the lifting rod 22 plays a buffering role when the second layer of the stage lift 1 moves up and down. The support rod 31 connected to the piston rod of the cylinder 21 rises or falls together with the piston rod. Since the support rod 31 is connected to the top layer of the stage lift 1, at this time, the top layer and the second layer of the stage lift 1 rise or fall simultaneously. When the top layer of the stage lift 1 rises or falls to the expected position, the support rod 31 can be locked by the pin 32 to prevent the top layer of the stage lift 1 from sliding when the cylinder 21 fails, causing a safety accident.

[0026] Embodiment 2: On the basis of Embodiment 1, as Figures 5-7 shown, it further includes a pulling mechanism 4. The pulling mechanism 4 is used to stretch the stage lift 1. The pulling mechanism 4 includes a connecting rod 41, a first rotating shaft 42, a fixing plate 43, a torsion spring 44, a second rotating shaft 45, a rope 46 and a slider 47. Two fixing plates 43 are fixedly connected to the front end of the bottom layer of the stage lift 1. The second rotating shaft 45 is rotatably connected between the two fixing plates 43. The first rotating shaft 42 is connected to the left side of the second rotating shaft 45. A slider 47 is slidably connected to the front end of the bottom layer of the stage lift 1. The slider 47 is used to fix the first rotating shaft 42. The torsion spring 44 is sleeved on the second rotating shaft 45. The two torsion springs 44 are respectively connected to the second rotating shaft 45 and the fixing plate 43. The rope 46 is wound around the second rotating shaft 45. Four connecting rods 41 are connected to the periphery of the top layer of the stage lift 1. The upper end of the rope 46 is connected to the connecting rod 41.

[0027] On the basis of Embodiment 1, as Figures 5-8 shown, it further includes an anti-tilting mechanism 5 for supporting and fixing the stage lift 1. The anti-tilting mechanism 5 includes a connecting rod 51, a telescopic rod 52 and a second pressure spring 53. Four telescopic rods 52 are connected to the bottom layer of the stage lift 1. A connecting rod 51 is connected between two adjacent telescopic rods 52. Four second pressure springs 53 are respectively sleeved on the telescopic rods 52. The two ends of the second pressure spring 53 are respectively connected to the telescopic rod 52 and the second layer of the stage lift 1.

[0028] The lifting of the top layer of the stage lift 1 can be controlled by manually rotating the first rotating shaft 42. Pull out the cotter pin 32, slide the slider 47 to the left, and manually rotate the first rotating shaft 42. The rotation of the first rotating shaft 42 will drive the rotation of the second rotating shaft 45. At this time, the rope 46 wound around the second rotating shaft 45 will, due to the rotation of the second rotating shaft 45, pull the connecting rod 41 of the top layer of the stage lift 1. The top layer of the stage lift 1 will move up or down due to the traction force of the rope 46. When it rises or falls to the expected position, insert the cotter pin 32, and then slide the slider 47 to the right to lock the first rotating shaft 42.

[0029] The four telescopic rods 52 of the anti-tilting mechanism 5 are connected into a rectangle through the connecting rod 51 and are placed around the bottom layer of the stage lift 1 to support and fix the stage lift 1. The second compression spring 53 sleeved on the telescopic rod 52 plays a buffering role when the stage lift 1 is lifted or lowered.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
