Description

Blade drive mechanism for three-dimensional statue Technical field

The invention relates to the technical field of stage machinery, in particular to a blade drive mechanism for a three-dimensional statue.

Background technique

Three-dimensional statues are an important part of the process of urban humanistic construction. There are movable three-dimensional statues in the existing three-dimensional statues, and the three-dimensional statue can move according to a predetermined track through the driving part, thereby improving the display effect of the three-dimensional statue. However, the existing movable three-dimensional statue can only complete a simple translation and close action, and only when the three-dimensional statue is in the closed state, can it give the audience a visual display of the statue. When it is in a separate position, each of the movable three-dimensional statue can be displayed. Part is disordered and cannot give people visual appreciation. Therefore, the existing movable three-dimensional statues generally have the problem that the movable action is simple and the outline of the statue is only in the closed state, and the display effect is poor.

Therefore, the applicant has filed a separate application on the same day for the structural design of various display of the three-dimensional statue. The purpose of this application is to solve how to set up a driving mechanism that can drive the movable blades of the three-dimensional statue.

Summary of the invention

The present invention aims to solve one of the technical problems in the related art at least to a certain extent: to provide a blade driving mechanism for a three-dimensional statue, which not only makes the blades of the statue present a contour shape in the gathered and dispersed states, but also can drive The structure of the organization is simple and reliable.

To this end, an object of the present invention is to provide a blade drive mechanism for a three-dimensional statue, which includes a bearing unit and a column erected on the bearing unit, and one or more circular traction chains are provided on the column. The upper part of the traction chain is sleeved on the fixed pulley on the top of the column, and the lower part of the traction chain passes downward through the blade installation area on the column and is connected to the traction chain drive mechanism on the load-bearing unit. The feature is that the traction chain is located on the column. The part of the blade installation area includes a functional section composed of at least one roller unit and a telescopic unit with an adjustable length. The column is laid with a guide rail for the roller unit to move along the axis of the column, so The guide rail is fixedly connected with the upright column, and at least one movable blade is installed on the traction chain, and the traction chain drives the movable blade up and down along the axial direction of the upright column. Through this drag chain structure with roller unit and telescopic unit, not only can the blades installed on the drag chain be moved by the pulling of the drag chain, but also because the rolling unit and the guide rail are matched, it greatly avoids the shaking of the drag chain. The blades fixed on the traction chain interfere with the column or the fixed accessories on the column, and the local length of the traction chain can be adjusted well by the telescopic unit, so that not only the axial position of the connected roller unit can be adjusted by the telescopic unit, so as to The adjustment of the blades on the roller unit and the adjustment of the length of the telescopic unit can facilitate the installation of the entire traction chain during the installation process, and also facilitate the adjustment of the tension of the traction chain during the subsequent maintenance process.

In order to meet the display requirements of the outer contours of different three-dimensional statues, the axis of the column is a curve extending in a vertical direction.

There are six traction chains, and the six traction chains are arranged at intervals along the circumferential direction of the upright column, and fixed pulleys are provided on the top of the upright column at the position corresponding to each traction chain.

The 6 traction chains form 12 parallel functional sections in the blade installation area, and all functional sections are evenly distributed along the circumference of the column.

In order to achieve a good control of the local position adjustment of the blades on the roller unit during the adjustment of the telescopic unit, it is preferable to arrange the telescopic unit and the corresponding roller unit adjacently, that is, any telescopic unit is adjacent to each other. The roller units are connected in rotation through a universal joint. In particular, the aforementioned universal joint can make the adjustment between the telescopic unit and the roller unit not only limited to the length direction.

The telescopic unit includes an upper adjusting rod, a lower adjusting rod and an adjusting sleeve. The upper adjusting rod and the lower adjusting rod are arranged at intervals along the same axis, and the opposite ends of the upper adjusting rod and the lower adjusting rod are respectively inserted into the two ends of the adjusting sleeve. , The upper adjusting rod and the adjusting sleeve, and the lower adjusting rod and the adjusting sleeve are all threaded connections, and the upper adjusting rod and the lower adjusting rod move relative or opposite to each other as the adjusting sleeve rotates. The length of the traction chain can be adjusted well by the telescopic unit, which is convenient for the installation of the traction chain and the maintenance and adjustment of the tension of the traction chain. In addition, the length adjustment of the telescopic unit can make the local position of the blades on the adjacent roller unit adjustable. Adjust to adjust the position of the blade.

The roller unit includes a roller body, and a sliding groove matched with the guide rail is provided on the roller body at a position corresponding to the guide rail.

The universal joint includes a male joint, a female joint, a rotating core block and a rotating shaft. One end of the male joint is fixedly connected with the telescopic unit, and the other end of the male joint is hinged with the rotating core block along a first rotation plane. One end of the female connector and the roller body are rotationally matched along the axis of the roller body, and the other end of the female connector is hinged with the rotating core block along a second rotation plane, and the two rotation planes are perpendicular to each other. Through the structural optimization of the universal joint, the load-bearing capacity of the universal joint is greatly improved compared with the conventional spherical joint. At the same time, the design of the rotating core block can well meet the needs of universal adjustment. In addition, due to the female joint It is matched with the roller unit to rotate around the axis of the roller body, so that the telescopic unit and the roller unit can be rotated in the circumferential direction at will, which facilitates the installation between the blade and the roller unit, and also facilitates the installation of the rear blade position Adjustment.

The roller body is provided with a guide wheel that is slidably matched with the guide rail, and the guide wheel is rotationally matched with the roller body around its own axis, and a sliding groove is formed on the outer circumference of the guide wheel.

The guide wheel includes a first guide wheel and a second guide wheel that are spaced apart along the axial direction of the roller body, and the first guide wheel and the second guide wheel are reserved with a connection area for installing movable blades. The two guide wheels spaced apart in the axial direction can form a connection area between the two guide wheels. When one or more connection points of the blade are located in the connection area, it can ensure that the blade moves with the drag chain. During the process, there will be no interference with the column or the accessories on the column.

In order to realize the requirement that the movable blade can simultaneously complete the circumferential rotation and axial movement of the blade, the movable blade includes a support ring and a blade body, the blade body is rotatably fitted on the support ring, and part or all of the support ring is connected to the support ring. The connection area of the roller body is connected. The traction chain is connected to the support ring of the movable blade, thereby driving the movable blade to move axially, and the blade body of the movable blade can rotate circumferentially around the supporting ring, thereby achieving the requirements of circumferential rotation and axial movement of the outer contour of the blade .

The first guide wheel and the second guide wheel are both multiple, and the outer circumferential surfaces of any two adjacent first guide wheels and the outer circumferential surfaces of the corresponding two second guide wheels are enclosed together to form a guide rail的chutes. With multiple guide wheels arranged at intervals in the circumferential direction, a V-shaped groove can be formed between two adjacent guide wheels in the horizontal direction as a sliding groove. The sliding groove is matched with the guide rail. This realizes the requirement of sliding the roller unit on the guide rail through a plurality of guide wheels.

The guide rail includes two guide rods parallel to each other, and both ends of the guide rod extend along the axis direction of the upright post. Using two guide rods as the guide rail design, four identical guide wheels on the same plane can be enclosed to form two symmetrical sliding grooves with opposite opening directions. Therefore, these two sliding grooves can not only guide the roller unit along the The rod slides in the length direction and because the distance between the center positions of the two chutes is smaller than the distance between the edges of the chutes, the roller unit can be well confined to the two guide rods to prevent disengagement during the sliding process. .

There are multiple roller units and telescopic units, and all roller units and telescopic units are arranged in sequence and connected to each other. Since there are multiple movable blades set on the column, the corresponding roller unit is preferably provided at the corresponding position of each movable blade, and the telescopic unit is provided at a position close to each roller unit to facilitate the expansion and contraction. The length adjustment of the unit realizes the leveling of the blades on the connected roller unit, and finally realizes the adjustment of all the movable blades on the entire column.

All roller units and telescopic units are arranged alternately in order.

The additional aspects and advantages of the present invention will be partly given in the following description, and partly will become obvious from the following description, or be understood through the practice of the present invention.

The above technical solution has the following advantages or beneficial effects: First, the roller unit on the traction chain can not only make the traction chain and the guide rail slide, so that the traction chain pulls along the axis of the column, but also can avoid the installation of the traction chain. The movable blade interferes with the column or the fixed attachment on the column during the pulling process of the traction chain, especially when the axis of the column is curved, through the mutual cooperation of multiple roller units, the blade can be well avoided along the predetermined trajectory Columns and fixed accessories on the column. Secondly, the telescopic unit can not only adjust the length of the traction chain to facilitate the installation and maintenance of the traction chain, but also adjust the position of the blades on the roller unit connected to the corresponding telescopic unit. Therefore, the telescopic unit takes into account the leveling function of the blades. Finally, the structural design of the universal joint between the roller unit and the telescopic unit can enable the traction chain to realize a universal connection and have a good bearing capacity.

Detailed ways

The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention, but should not be construed as limiting the present invention.

Hereinafter, a movable three-dimensional statue according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The present invention provides a three-dimensional statue, which includes a plurality of upright columns 100 as shown in the figure, each of the uprights 100 is provided with a blade unit 200, and the upright 100 is provided with a blade driving unit for driving the blade unit 200 300. The lower end of the column 100 is installed on the bearing unit 400, and the column 100 is driven by the bearing unit 400 to move the column 100 in the horizontal direction, so that the blade units on the columns 100 cooperate with each other when the columns 100 are gathered together. The overall outline of the statue, so as to visually display the overall statue shape to the audience, and when the columns 100 are reset to be far away from each other, the blade units 200 on the columns 100 are driven by the respective blade drive units 300 to make the blade units The leaves in 200 are rearranged and combined to form a single pattern, such as a flower state as shown in FIG. 13. In the end, the original single three-dimensional statue can be displayed in at least two different shapes. All the blade units 200 on the above-mentioned column 100 can be collectively referred to as movable parts on the three-dimensional statue.

Example one:

As shown in FIG. 3, the blade unit 200 in the above-mentioned three-dimensional statue includes a plurality of blades 201, all the blades 201 are sleeved outside the column 100, and the blades 201 are arranged at intervals along the length of the column 100 in sequence. At least one blade 201 or all blades 201 of all the blades 201 described above include a blade body 2011 and a support ring 2012 for carrying the blade body 2011. The support ring 2012 is sleeved outside the column 100 and connected to the column 100. The blade The main body 2011 is mounted on the support ring 2012, and the blade main body and the support ring 2012 are rotated along the axial limit of the column 100 along the circumferential direction of the column 100. The blade main body 2011 is provided with the blade main body 2011 to be opposed to each other. The blade motor 301 that rotates on the support ring 2012, that is, the blade body 2011 is rotated by the blade motor 301 in the blade drive unit 300. Of course, what is used to drive the blade main body 2011 to rotate may also be a conventional driving component such as a hydraulic motor. Based on this, the following includes but is not limited to a conventional blade motor 301 as an example in order to describe the movement process of the support ring 2012.

In order to form the outer contour of the three-dimensional statue, the outer edges of the blade bodies 2011 arranged in sequence need to be constructed into the outer contour figure of the preset three-dimensional statue. Therefore, the outer contour of each blade body 2011 in the horizontal direction on the same column 100 All adjustments are made based on the design requirements of the contour shape, but the coordination between each blade body 2011 and the support ring 2012 can adopt the same or different connection mechanisms, which is allowed.

Specifically, the blade body 2011 is composed of an upper layer blade plate and a lower layer blade plate. The upper layer blade plate and the lower layer blade plate are spaced apart and fixedly connected to each other. The blade body 2011 sequentially penetrates the blade body along its own thickness direction. The upper blade plate and the lower blade plate of 2011 form a mounting through hole, the size of the mounting through hole matches the support ring 2012, and the support ring 2012 is limited to the upper blade plate and the lower blade plate along the thickness direction of the blade body 2011 In between, and the support ring 2012 rotatably cooperates with the blade body 2011 through a bearing.

Preferably, as shown in FIG. 11, the blade motor 301 is arranged between the upper blade plate and the lower blade plate of the blade body 2011, so that the built-in design of the blade motor 301 can at least play a role in wind and rain protection. . One of the above-mentioned examples of driving the support ring 2012 through the blade motor 301: a driving gear is provided on the output shaft of the blade motor 301, and an arc-shaped rack is provided on the outer circumference of the support ring 2012, through the driving gear and the arc-shaped rack. The meshing between the two causes the driving force of the blade motor 301 to be transmitted to the support ring 2012. Since the support ring 2012 is fixedly connected to the column 100, the blade body 2011 drives the blade motor 301 to rotate around the column 100 under the push of the reaction force.

Preferably, the above-mentioned support ring 2012 can be used as a part of the blade, so that the blade is divided into a movable part and a fixed part, that is, the support ring 2012 as the fixed part is connected to the column 100, and the blade body 2011 and the support ring 2012 as the movable part are connected. Rotational fit between. In addition, the above-mentioned support ring 2012 can be used as an independent component, through which the blade and the column 100 are rotationally matched, that is, the support ring 2012 as an independent component is fixed to the column 100, and the blade and the support ring 2012 are fixed between the blade and the column 100. For rotational cooperation, in this sense, the entire blade rotates around the column 100. Of course, a blade motor 301 is also provided in the blade. The output shaft of the blade motor 301 meshes with the support ring 2012 through a transmission gear to drive the blade relative to the support ring. 2012 turns.

Of course, in the example, the blades 201 in the blade unit 200 are all discussed through the support ring 301 to achieve rotation cooperation with the column 100; of course, in the actual assembly process, it is not strictly required that all the blades adopt this rotatable structural design. The blade 201 does not need to be rotated, and the blade 201 that does not need to be rotated is directly fixedly connected to the column. At this time, the common knowledge in the industry will not be repeated here. When all the blades 201 can be rotated, it is of course possible to choose not to rotate. Therefore, all the blades 201 discussed below are rotatable.

Embodiment two:

The basic structure is the same as the first embodiment, the difference is: as shown in Figs. 3-9, the number of blades 201 on the single column 100 is N, and all the N blades 201 are sequentially divided into M groups of blade groups, among which, N is an integer greater than 2, and M is an integer less than N and greater than 1. And the blade group with more than two blades 201 included in the M group of blade groups is composed of at least one reference blade 201-0 and at least one movable blade 201-S, that is, at least one blade 201 in the blade group is the reference blade 201 -0, the remaining blades 201 are movable blades 201-S. Take the blade group composed of 5 blades 201 in the M group of blade groups as an example, the blade 201 in the middle position in the blade group is the reference blade 201-0, and the upper part of the reference blade 201-0 is arranged at intervals. One movable blade 201-S1 and the upper two movable blades 201-S1, and the next movable blade 201-S3 and the lower two movable blades 201-S4 are sequentially spaced below the reference blade 201-0. The support ring 2012 of the reference blade 201-0 is fixedly connected to the column 100, and the blade body 2011 of the reference blade 201-0 is rotatably matched with the support ring 2012 so that the blade body 2011 of the reference blade 201-0 only runs along the column 100. The column 100 rotates in the circumferential direction. The support rings 2012 of the four movable blades 201-S are connected to the column 100 through their corresponding axial movable mechanisms, that is, the movable blades 201-S realize axial movement through the axial movable mechanism 302 in the blade drive unit 300, and The axial movement mechanism 302 can drive the support ring 2012 of the movable blade to move along the axial direction of the column 100, and the effect achieved by this is that not only the blade body 2011 of the movable blade 201-S can be rotated and matched with the respective corresponding support ring 2012 In this way, it is realized that the blade body 2011 of the movable blade 201 -S can rotate around the circumference of the column 100, and the supporting ring 2012 can drive the blade body 2011 to move along the axial direction of the column 100 through the axial movement mechanism 302. The overall effect presented by the above-mentioned movable blades 201-S is that the blade bodies 2011 of the five blades 201 can all rotate around the circumference of the column 100, and at the same time, the four movable blades 201-S can converge or face toward the position of the reference blade 201-0. The direction away from the reference blade 201-0 is reset.

Preferably, the purpose of setting the blade 201 in the middle position as the reference blade 201-0 in the same blade group is to make the total stroke of each movable blade 201-S moving toward the reference blade 201-0 smaller. Of course, it is not excluded to use any blade 201 in the blade group as the reference blade 201-0. For example, in a blade group composed of five blades 201, the first blade 201 from top to bottom can be used as the reference blade 201-0. The four blades 201 located below the reference blade 201-0 are movable blades 201-S; the second blade 201 from top to bottom can also be used as the reference blade 201-0, and one blade located above the reference blade 201-0 201 and the three blades 201 located below the reference blade 201-0 are used as movable blades 201-S; the fourth blade 201 from top to bottom can also be used as the reference blade 201-0, and the 3 above the reference blade 201-0 One blade 201 and one blade 201 located below the reference blade 201-0 are used as movable blades 201-S; the fifth blade 201 from top to bottom can also be used as the reference blade 201-0, which is located above the reference blade 201-0 The four blades 201 are movable blades 201-S.

Preferably, the total number of blades 201 in the aforementioned single blade group may be 2, 3, 4, 5, 6 or more.

Further, when the total number of blades 201 is an odd number, the middle blade 201 is selected as the reference blade 201-0, thereby making the axial movement path of each movable blade 201-S small, reducing errors and control difficulties caused by movement.

Embodiment three:

The basic structure is the same as that of the second embodiment. The difference is: as shown in FIG. 14, the reference blade 201-0 may not be set in the blade group composed of one or more blades, but a virtual reference plane O is preset. All the blades 201 in the blade group are moved toward the reference plane O through the axial movement mechanism 302 to realize the display effect of being gathered to form a flower pattern, or to reset the flower pattern from the gathered state to the initial state.

Especially when the number of blades 201 in a single blade group is an even number, it is impossible to find a reference blade 201-0 in the middle of the axial direction, so this reference plane O needs to be set, and the reference plane O mentioned above can be selected along the column 100 A plane on the axis where any point in the area corresponding to the blade group is located.

Preferably, for the consideration of the symmetry of the force, the midpoint is found at the axially centered position of the blade group, and a virtual reference plane O is formed through the midpoint. The blades 201 in the blade group are evenly distributed in the axial direction. It is divided into upper and lower parts, thus facilitating the symmetrical design of the upper and lower parts of the blade 201 during the movement process. Obviously, after replacing the reference blade 201-0 in the second embodiment with the reference plane O, all the blades 201 in the blade group are movable blades. 201-S.

Of course, due to the comprehensive consideration of the position, height, association of adjacent parts, and blade movement stroke during the assembly process of the blade 201, only one reference blade 201-0 or multiple reference blades may be provided in a blade group. 201-0, or setting a reference plane O, or setting multiple reference planes O, or setting at least one reference blade 201-0 and at least one reference plane O combination should be allowed, the above reference plane O and/or The selection of the reference blade 201-0 is based on the preferred changes after the above technical solution of the present application.

Embodiment four:

The basic structure is the same as the second embodiment, the difference is: as shown in FIG. 19, the axial movable mechanism 302 includes a traction chain 3021 extending along the axial direction of the column 100, the support ring 2012 of the movable blade 201-S and the traction chain 3021 is fixedly connected, and the drag chain 3021 only moves along the axis direction of the column 100, thereby driving the movable blades 201-S fixedly connected to the drag chain 3021 to move along the axial direction of the column 100.

Specifically, the above-mentioned drag chain 3021 only needs to move along the axis of the column 100 to achieve a certain limit mechanism and a drag chain drive mechanism, but the limit mechanism of the drag chain 3021 can be achieved by additional guide rails or guide grooves or guide wheels. To achieve the limit function, the traction chain drive mechanism can be realized by conventional driving methods such as a motor plus a transmission gear or a motor plus a sprocket or a hydraulic cylinder. Obviously, the movement of the traction chain 3021 only along the axis of the column 100 can be achieved by using a variety of conventional existing technologies. Those of ordinary skill in the art can use the existing technologies in the field or even the well-known fields to realize the traction chain 3021 only along the axis. The column 100 moves in the axial direction. Therefore, the specific conventional structure of the drive traction chain 3021 is not listed in this embodiment and does not affect the technical reproduction of the traction chain 3021 that the traction chain 3021 only moves along the axis direction of the column 100 by those skilled in the art. This will be repeated in detail.

Embodiment five:

The basic structure is the same as that of the second embodiment. The difference is: as shown in Figure 2, taking the number of blades 201 on a single column 100 as an example, every 5 blades 201 are divided into a blade group, thereby making 45 blades 201 is divided into 9 blade groups in sequence from top to bottom, and the middle blade 201 in any blade group is the reference blade 201-0. The upper and lower sides of the reference blade 201-0 are respectively provided with a movable blade 201 -S1 and the next movable blade 201-S3, the upper two movable blades 201-S2 are provided above the previous movable blade 201-S1, and the lower two movable blades 201-S4 are provided below the next movable blade 201-S3, so The movement stroke of the two movable blades 201-S2 toward the reference blade 201-0 is greater than the movement stroke of the previous movable blade 201-S1, and the movement stroke of the upper two movable blades 201-S2 is substantially the movement of the previous movable blade 201-S1 2 times the stroke, the movement stroke of the lower two movable blades 201-S4 toward the reference blade 201-0 is greater than the movement stroke of the next movable blade 201-S3, and the movement stroke of the next two movable blades 201-S4 is substantially the next The movable blade 201-S3 moves twice as long.

Of course, both the vertical straight shaft and the curved crankshaft are collectively referred to as the column 100.

Embodiment Seven:

The basic structure is the same as that of the fourth embodiment, the difference is: as shown in Figure 19 to Figure 21, in order to make the drag chain 3021 can be applied to the curved column 100, that is, the length of the drag chain 3021 itself is curved along the column 100 The axis extends, in order to avoid interference between the traction chain 3021 and other accessories on the column 100 at the curved part and the difference in the stroke of the traction chain 3021 with different curved parts, the structure of the traction chain 3021 has been improved and designed. The traction chain 3021 is at least It is composed of a plurality of alternately arranged roller units and telescopic units connected in sequence, and the two ends of any telescopic unit are respectively connected with adjacent roller units through universal joints.

Preferably, in order to reduce the number of traction chains 3021, the traction chain 3021 can adopt an endless structure connected end to end. The top of the column 100 is provided with a fixed pulley 304 that matches the traction chain 3021, and the upper part of the traction chain 3021 is wound around Outside the fixed pulley 304, it is possible to make an endless drag chain 3021 after passing the fixed pulley 304 to form two sections with one section rising and the other section falling synchronously. Therefore, two sets of traction chain drive mechanisms for driving the traction chain can be formed. Simplified to a set of traction chain drive mechanism.

Preferably, the purpose of installing the roller unit and the telescopic unit on the traction chain 3021 is to facilitate the installation and adjustment of the movable blades. Therefore, when the traction chain 3021 is located at the position of the fixed pulley 304, it is not necessary to install the roller unit and the telescopic unit. The part of the same drag chain 3021 that extends to the carrying unit 400 only needs to be connected to the drag chain driving mechanism on the carrying unit 400, so there is no need to provide a roller unit and a telescopic unit. Therefore, the entire endless traction chain includes, but is not limited to, at least one roller unit, at least one telescopic unit with an adjustable length, and at least one end chain 3030 connected end to end in sequence. Of course, as mentioned above, the reason why the roller unit and the telescopic unit are provided on the traction chain 3021 is to facilitate the installation of the movable blades. On the basis of taking into account the movement of the movable blades according to the predetermined path, it is necessary to avoid the fixing of the movable blades and the column or the column. Interference and collision of accessories, especially when the axis of the column 100 is curved, using a conventional chain pull will greatly cause the movable blades to touch the curved part of the column 100, causing equipment damage. Therefore, the roller unit and the telescopic unit should be set The area corresponding to the movable blade on the upright 100. Therefore, an area on the column 100 where the movable blade is located is considered to be a blade installation area 305, and the blade installation area 305 is an annular area formed around the axis of the column 100. The part of the traction chain 3021 located in the blade installation area 305 is defined as a functional section, and the roller unit and the telescopic unit constituting the traction chain 3021 are located in the blade installation area 305.

A fixed pulley 304 is provided at the corresponding position. In addition, the six traction chains pass through the blade installation area 305, so that all the traction chains 3021 form 12 parallel functional sections in the blade installation area 305, and all the functional sections are evenly distributed along the circumferential direction of the column 100.

The area between the wheels 3021-2" leaves a connecting area 3021-3 for connecting the movable blades 201.

Specifically, the number of the first guide wheels 3021-2' and the second guide wheels 3021-2" are both four, and the four first guide wheels 3021-2' are evenly distributed along the circumference of the roller body 3021-1 , The four second guide wheels 3021-2” are also evenly distributed along the circumference of the roller body 3021-1, and any one of the second guide wheels 3021-2” is along the axial direction of the roller body 3021-1 and one of the first guides The wheels 3021-2' correspond to each other, so that the four first guide wheels 3021-2' and the four second guide wheels 3021-2" are in one-to-one correspondence along the axial direction of the roller body 3021-1. And the outer circumferential surfaces of the two first guide wheels 3021-2' and the outer circumferential surfaces of the two first guide wheels 3021-2' corresponding to the two second guide wheels 3021-2" in the axial direction are jointly formed The inner surface of the sliding groove slidingly fitted with the guide rail. Similarly, the outer circumferential surfaces of the remaining two first guide wheels 3021-2' and the outer circumferential surfaces of the two axially corresponding second guide wheels 3021-2” are also The inner surfaces of the sliding grooves in opposite directions are formed by enclosing together, so that the two oppositely facing sliding grooves and the two on the guide rail are formed by four first guide wheels 3021-2' and four second guide wheels 3021-2”. A sliding surface fits or a sliding fit with the two components of the guide rail, not only can achieve a good sliding fit of the roller body 3021-1 on the guide rail, but also make the roller body 3021-1 constrain on the guide rail, reducing the roller body 3021 -1 The risk of derailing from the rail. Of course, the above-mentioned rail structure needs to be set to match the two chutes. The adaptive adjustment of the rail can be caused by deforming the rail to form a different mating surface, or by The multiple component parts of the guide rail are realized in cooperation. Therefore, in this embodiment, when the roller unit makes the above structural improvement, the corresponding guide rail needs to be adjusted adaptively.

The stroke of -0 movement is also different, so each of the 4 movable blades 201-S needs to be connected to the respective drag chain 3021 through 3 connection points, so the 4 movable blades 201-S need to pass Only 12 traction chains 3021 can complete the axial driving of the movable blades 201-S. Of course, each movable blade 201-S in the 9 blade groups can be connected to the respective drag chain 3021, so all movable blades 201-S on a single column 100 can be pulled by 12 drag chains 3021 to achieve 9 The leaf groups are unfolded in an initial state parallel to each other, or gathered together in a state of 9 flowers.

Embodiment 12:

The basic structure is the same as that of the eleventh embodiment, the difference is: taking 5 blades to form a blade group as an example, the blade 201 in the middle position is the reference blade 201-0, and the upper two movable blades 201- in order from the top to the bottom. S2, the previous movable blade 201-1S1, the reference blade 201-0, the next movable blade 201-S3 and the next two movable blades 201-S4, while the previous movable blade 201-S1 and the next movable blade 201-S3 are along the The reference blade 201-0 is designed symmetrically, and the upper two movable blades 201-S2 and the lower two movable blades 201-S4 are also symmetrically designed along the reference blade 201-0. Therefore, the path lengths of the previous movable blade 201-S1 and the next movable blade 201-S3 toward the reference blade 201-0 at the intermediate position are the same, the upper two movable blades 201-S2 and the lower second movable blade 201- The length of the path that S4 moves toward the reference blade 201-0 at the intermediate position is also the same. Therefore, the moving path of the drag chain 3021 that drives the previous movable blade 201-S1 and the drag chain 3021 that drives the next movable blade 201-S3 are the same, the difference is that one of the two drag chains 3021 moves downwards , The other is moving upwards. Based on this requirement, the present application connects the upper ends of the two drag chains 3021 corresponding to the previous movable blade 201-S1 and the next movable blade 201-S3 to form an integral drag chain 3021. The upper end is reversed by the fixed pulley 304 installed at the top of the column 100, which can solve the problem that one section of the traction chain 3021 is ascending and the other section is descending. Similarly, the moving paths of the drag chain 3021 that drives the upper two movable blades 201-S2 and the drag chain 3021 that drives the lower two movable blades 201-S4 to move are also the same. The upper ends of the two drag chains 3021 corresponding to 201-S2 and the lower two movable blades 201-S4 are connected to each other to form an integral drag chain 3021. The upper end of the drag chain 3021 is replaced by a fixed pulley 304 installed at the top of the column 100 Therefore, it can be solved well that one section of the traction chain 3021 is ascending and the other section is descending. As a result, a blade group consisting of 4 movable blades 201-S and a reference blade 201-0 only needs two drag chains 3021 to drive the 4 movable blades 201-S to move up and down, which will greatly reduce The number of driving components that drive the traction chain 3021 to move simplifies the overall structure. At the same time, since a whole traction chain 3021 is looped through the fixed pulley 304, the traction chain 3021 has the same rising and falling distances, reducing control difficulty.

Taking 4 movable blades 201-S as an example, each movable blade 201-S needs 3 drag chains 3021 to realize positioning installation, so a total of 12 drag chains 3021 are needed, and the drag chains 3021 and descenders with the same stroke are used for lifting The drag chains 3021 used can be connected to each other to form a whole, so the 12 drag chains 3021 described above can be simplified into 6 drag chains 3021.

Further, when the upper ends of the two traction chains 3021 are connected to each other so as to realize reversing around the fixed pulley 304, the lower ends of the two traction chains 3021 can also be connected to each other, so that the traction chains 3021 are connected end to end. The 4 movable blades 201-S on a blade group require 6 circular drag chains 3021, and the 45 blades on the column 100 can be divided into 9 blade groups, and each blade group can be separately It is connected with the respective endless drag chains 3021, so that although the entire column 100 has 9 blade groups, only 6 endless drag chains 3021 are needed, which can greatly reduce the number of drag chains 3021, of course, the blade group The number of inner movable blades 201-S can be increased or decreased, or the path lengths of different movable blades 201-S in the blade group are divided into multiple different lengths. At this time, the number of drag chains 3021 will change accordingly. This change can be Based on the number of movable blades 201-S in a single blade group, the movable blades 201-S are summarized into several stroke lengths, and whether the motion formation of the movable blades 201-S between each blade group is the same to calculate the corresponding drag chain 3021 Quantity. Therefore, the number of the above-mentioned drag chains 3021 can be obtained by simple calculation based on actual demand, so the examples are not given here.

Preferably, the position of the above-mentioned closed-loop traction chain 3021 at the position of the blade 201 requires the use of the roller unit and the telescopic unit of the above-mentioned traction chain 3021 to realize the pulling on the curved column, but it should be understood as including but not limited to the entire closed-loop traction chain 3021 Both are composed of roller units and telescopic units. When there is no need for guidance in the part of the traction chain, the conventional chain 3030 can be used for connection due to cost and connection strength considerations, thereby reducing the number of roller units and telescopic units, that is, the entire traction The chain 3021 should be understood as a multi-section end-to-end splicing structure. One or more sections of the traction chain 3021 can be constructed with the above-mentioned alternate structure of roller units and telescopic units, and the rest can be connected by a conventional chain 3030.
