Description

Improved mobile stage truck elevator stage

The utility model relates to a kind of mobile stage truck elevator stage, particularly relate to a kind of simple in structure, support performance is good and lifting is easy to the mobile stage truck elevator stage.

Mobile stage truck is a kind of vehicle that forms the long plate shape mainboard at the headstock rear, sets up stage on mainboard, stage and car are gone together and forms activity form, freely arrives outdoor vacant lot, and the place of various performance or speech promptly is provided.

Illustrated in figures 1 and 2 is a kind of " (the lift stage of mobile stage truck " utility model patent, and this lift stage 10 includes first cylinder pressure 11 and second cylinder pressure 12.One end of first cylinder pressure 11 is articulated on the main cylinder pressure 13 and is fixed in backup plate 101 tops at headstock rear, and the other end then frame is connected to the connecting rod 15 1 sides top that connects stage plate 14; One end of second cylinder pressure 12 is articulated in the below of connecting rod 15, and the other end then is articulated on the stage plate 14.When first cylinder pressure 11 moves, promote connecting rod 15 tops and make it outwardly and make progress to rise, drive simultaneously and move rising outside the stage plate 14.Because connecting rod 15 is vertical pivot joint with 14 of stage plates, so be able to make progress outwardly gradually by the angle adjustment of second cylinder pressure 12.Yet this kind mechanism is when elevating movement, and stage plate 14 can't be kept level, and is formed with very big angle with ground, causes the performer can't be stood.

Fig. 3 and Figure 4 shows that another kind " the lift stage of mobile stage truck " utility model patent, the more aforesaid lift stage of the structure of this lift stage 20 is simplified to some extent, cylinder pressure 21 1 ends are fixed in backup plate 201 tops at headstock rear equally with main cylinder pressure 22 pivot joints, the other end then is articulated in the middle position of connecting rod 23, promote connecting rod 23 middle positions by cylinder pressure 21, make it towards and move up, this moment stage plate 24 with the action of connecting rod 23 simultaneously outwardly and move upward, and can keep level and move outward and rise, though this mechanism can realize the 24 horizontal liftings of stage plate, but when stage plate 24 rises fully, cylinder pressure 21 is a parastate with stage plate 24 and connecting rod 23, for this reason, when stage plate 24 needs to descend, the great pulling force of cylinder pressure 21 necessary loads is stretchy connecting rod 23 and stage plate 24, need have splendid intensity just can support stage and carry out lifting.No matter being first kind or second kind of mechanism design, all is that free ending pivot with cylinder pressure is connected on the connecting rod and directly forces on the connecting rod, the stage plate firmly and easily can't be propped up, and structure is complicated; In addition, when the stage plate rose fully, cylinder pressure and stage plate were parastate, and causing needs great pulling force just can finish when descending.

The purpose of this utility model promptly is the improvement in addition suitable to the structure of mobile stage truck elevator stage, makes it designs simplification and lifting steadily, easily.

To achieve these goals, the utility model directly is articulated in the stiff end of cylinder pressure the gripper shoe below at headstock rear, its free end then is articulated in appropriate location on the stage plate, thereby helping directly promoting the stage plate moves outward and rises, when the stage plate rises fully, have an elevation angle between cylinder pressure and stage plate, help the stage plate and finish down maneuver easily.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the improved mobile stage truck elevator stage of the utility model.

The explanation of critical piece figure number:

10 lift stages, 101 backup plates, 11 first cylinder pressures, 12 second cylinder pressures, 13 main cylinder pressures, 14 stage plates, 15 connecting rods, 20 lift stages, 201 backup plates, 21 first depression bars, 22 main cylinder pressures, 23 connecting rods, 24 stage plates, 30 elevator stages, 301 stage sweeps, 31 gripper shoes, 311 first pin-jointed structures, 312 run through groove, 313 second pin-jointed structures, 32 connecting rods, 33 cylinder pressures, 34 stage plates, 341 the 3rd pin-jointed structures, 342 the 4th pin-jointed structures, 35 stage plates, 351 the 3rd pin-jointed structures, 352 the 4th pin-jointed structures.

Fig. 5 is the stereoscopic schematic diagram of elevator stage of the present utility model, this elevator stage 30 comprises gripper shoe 31, connecting rod 32, cylinder pressure 33 and stage plate 34, wherein gripper shoe 31 is fixedly arranged on the headstock rear, both sides, one end top respectively are provided with one first pin-jointed structure 311 and articulate with an end of connecting rod 32 respectively, and the other end of connecting rod 32 then articulates with stage plate 34; The bottom center place of gripper shoe 31 is provided with a long shape of a hoof and runs through groove 312, this inner wall that runs through groove 312 is provided with second pin-jointed structure 313, so as to articulating with cylinder pressure 33, the free end of cylinder pressure 33 then is articulated on the stage plate 34, make cylinder pressure 33 be able to activity by the space of running through groove 312 formations, constitute a complete elevator stage 30 according to this.

Operating principle of the present utility model is, make cylinder pressure 33 free ending pivots be connected on the stage plate 34, directly promoting stage plate 34 moves and rising outwardly, wherein ora terminalis both sides of stage plate 34 respectively are provided with one the 3rd pin-jointed structure 341, so as to being connected with connecting rod 32, and stage plate 34 centre between this both sides the 3rd pin-jointed structure 341 are provided with the 4th pin-jointed structure 342 in addition, so as to articulating with cylinder pressure 33.Fig. 6 is the initial state schematic diagram of elevator stage of the present utility model, the stiff end of its intermediate pressure cylinder 33 is articulated in the below of gripper shoe 31, also can be articulated in (not shown) on the stage sweep 301, its free end then articulates with the 4th pin-jointed structure 342 of stage plate 34.During initial state, cylinder pressure 33 and stage plate 34 all are positioned at the lower position of gripper shoe 31, making the free end of cylinder pressure 33 promote stage plate 34 moves outwardly and rises, drive by connecting rod 32 makes it to be level and slowly rise (as shown in Figure 7) with ground level, when stage plate 34 is complete propradation, 34 of cylinder pressure 33 and stage plates have an elevation angle, firmly support to arrive in stage plate 34, its support performance is good, and when stage plate 34 descends, also can leave behind easily, and need not to use the cylinder pressure of specific intensity, can the smooth-going easily lifting action of finishing stage plate 34.

Fig. 8 be elevator stage of the present utility model the initial state schematic diagram two, one ora terminalis both sides of stage plate 35 are provided with the 3rd pin-jointed structure 351 equally, its root edge appropriate location (as centre) then is provided with the 4th pin-jointed structure 352, make cylinder pressure 33 directly be articulated in the root edge centre of stage plate 35, stage plate 35 is firmly propped up outwardly and upwards, it reaches vertical motion outwardly and all keeps horizontal, and the action that helps performer on the stage is carried out.

In sum, the improved mobile stage truck elevator stage of the utility model has practicality really, cylinder pressure directly is supported in can make its lifting and support part smooth-going stable on the stage plate, and makes it simple in structure.
