Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a double synchronous line elevator. Background Art

[0002] In order to obtain a specific visual effect, some entertainment, performance venues or exhibition stands use liftable lamps, display screens, props, etc. At present, the lifting of lamps, display screens and props is achieved by a lift, which is mainly composed of a chassis, a winding mechanism arranged inside the chassis, and a winding power mechanism.

[0003] Single-cable lifts can suspend spherical or cylindrical lamps, and even if the lamps rotate, it will not affect the lighting effect. However, for some stage props, such as matrix lights and display screens, the projection of these devices is directional, so these props need to be prevented from rotating after being suspended, and the lifting must be very stable, but the current single-cable lifts cannot guarantee smooth lifting.

[0012] A further improvement is that a suspension support rod is connected between the left and right hanging ears, and the suspension support rod passes through the first vertical plate and the second vertical plate.

[0013] A further improvement is that a plurality of support columns are provided between the first vertical plate and the second vertical plate, one end of each support column is fixedly connected to the first vertical plate, and the other end of each support column is fixedly connected to the second vertical plate.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0025] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "transmission-connected" to another element, the two can achieve power transmission, and its specific implementation method can be implemented using the existing technology, which will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] The “first” and “second” involved in the present utility model do not represent specific quantities and orders, but are merely used to distinguish names.

[0028] Please refer to the attached Figure 1 -Attached Figure 4 , an embodiment of the utility model proposes a dual-synchronous line elevator, the elevator chassis (not shown in the figure) includes a supporting mechanism, a lifting drive mechanism and a wire-retracting mechanism, the supporting mechanism is used to support the lifting drive mechanism and the wire-retracting mechanism, the wire-retracting mechanism includes a first winding drum 1 and a second winding drum 2, the first winding drum 1 is wound with a first load-bearing wire rope 3, the second winding drum 2 is wound with a second load-bearing wire rope 4, the lifting drive mechanism includes a high-voltage drive motor 5 and a reducer 6, the output shaft of the high-voltage drive motor 5 is connected to the input shaft of the reducer 6, the output shaft of the reducer 6 is a two-end rotating shaft 7, one end of the two-end rotating shaft 7 is fixedly connected to the first winding drum 1 for driving the first winding drum 1 to retract and release the wire, and the other end of the two-end rotating shaft 7 is fixedly connected to the second winding drum 2 for driving the second winding drum 2 to retract and release the wire.

[0029] It is understandable that the wire rope of the drum winding type elevator in the prior art moves horizontally when lifting and lowering, and cannot maintain fixed-point lifting. However, the first winding drum 1 and the second winding drum 2 of the utility model are both disc structures. When winding, the wire rope is reeled in and released in a superimposed winding manner, which reduces the damage to the wire rope caused by the lateral torque of the wire rope, and can also keep the suspension point at the same position for vertical lifting.

[0030] Specifically, the first load-bearing rope 3 and the second load-bearing rope 4 can extend out of the elevator chassis, and connect and pull the light-emitting device (LED lamp, animation screen, etc.). The utility model drives the two-end rotating shaft 7 of the reducer 6 to rotate through the high-voltage drive motor 5, thereby driving the first winding drum 1 and the second winding drum 2 to rotate, increasing or reducing the number of winding turns to achieve the effect of synchronous and smooth lifting. The high-voltage drive motor 5 has greater advantages in driving torque and kinetic energy than ordinary low-voltage drive motors. The high-voltage drive motor 5 can provide a greater driving torque when working. At the same time, the addition of the reducer 6 can better utilize the driving torque, further improve the transmission efficiency, reduce energy loss, and thus improve the overall power output efficiency.

[0031] In this embodiment, the first load-bearing rope 3 and the second load-bearing rope 4 can be in two situations. The first situation is that the first load-bearing rope 3 and the second load-bearing rope 4 are both high-voltage cable ropes. The high-voltage cable ropes can be used for power supply and load-bearing at the same time. This situation can be used to hoist 2 high-power lamps of different specifications and lift them at the same time. The second situation is that the first load-bearing rope 3 is a high-voltage cable rope, and the second load-bearing rope 4 is a gigabit network rope. The high-voltage cable rope can be used for power supply and load-bearing at the same time. The gigabit network rope can be used for network signal transmission and load-bearing at the same time. This situation can be used to hoist large LED screens and interactive animation screens: for example, when projecting characters and animations on the high-altitude LED screen at a large concert, the high-voltage cable rope is used for high-voltage power supply, and the gigabit network rope is used for network transmission. In this way, the high-voltage cable rope and the gigabit network rope do not affect each other, and real-time transmission of network images can be realized, the network is more stable, the transmission distance is long, and the image is better.

[0032] In the preferred embodiment of the present invention, the outer skin of the first load-bearing cord 3 and the second load-bearing cord 4 is made of wear-resistant polyurethane (PUR) material, and the outer skin of the first load-bearing cord 3 and the second load-bearing cord 4 and the inner conductor are filled with tensile-resistant material. In addition, the present invention also uses high-density PE HDPE material to thicken the inner conductor.

[0033] It is understandable that polyurethane material has the advantages of wear resistance, oil resistance, good softness, etc., which can reduce the friction of the cord during use and prolong the service life. The first load-bearing cord 3 and the second load-bearing cord 4 can be directly used as 220V high-voltage cable cords, or as gigabit network cords. The transmission of network cables is more stable and can reach the gigabit network level. It can transmit high-definition video and high-pixel LED screens, and the application scenarios are flexible and changeable.

[0034] In a preferred embodiment of the present invention, the tensile-resistant material includes nylon thread and cotton rope. It is understandable that by filling nylon thread and cotton rope, the bearing capacity of the first load-bearing rope 3 and the second load-bearing rope 4 is increased, and the service life of the rope is increased. After testing, the service life of the rope in the present embodiment can reach 1300 hours.

[0035] In this embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the supporting mechanism includes a load-bearing crossbeam 8, a first vertical plate 9, and a second vertical plate 10. A supporting plate 11 parallel to the load-bearing crossbeam 8 is fixed below the load-bearing crossbeam 8. The first vertical plate 9 and the second vertical plate 10 are parallel to each other, and the top ends of the first vertical plate 9 and the second vertical plate 10 are respectively extended laterally to form a mounting plate 12 parallel to the supporting plate 11. The top surface of the mounting plate 12 is in contact with the bottom surface of the supporting plate 11 and fixed by screws. The lifting drive mechanism is fixedly installed between the first vertical plate 9 and the second vertical plate 10. The first winding drum 1 is located on the outer side of the first vertical plate 9 and is parallel to the first vertical plate 9. The second winding drum 2 is located on the outer side of the second vertical plate 10 and is parallel to the second vertical plate 10. One end of the two-end rotating shaft 7 passes through the through hole of the first vertical plate 9 and is fixedly connected to the first winding drum 1. The other end of the two-end rotating shaft 7 passes through the through hole of the second vertical plate 10 and is fixedly connected to the second winding drum 2.

[0036] It can be understood that the first vertical plate 9 and the second vertical plate 10 constitute a 'double main bridge plate' structure. By arranging the load-bearing crossbeam 8 and the support plate 11 on the double main bridge plate, the overall skeleton structure of the double main bridge plate is stable, so as to better support the lifting drive mechanism and the retractable wire mechanism, and the lifting is more stable. In addition, the first vertical plate 9 and the second vertical plate 10 can be provided with perforations, and then a safety rope can be connected to the perforations to achieve a better lifting protection effect.

[0037] In this embodiment, a plurality of screw holes are provided on the fixing seat of the reducer 6, and a plurality of mounting holes are respectively provided on the first vertical plate 9 and the second vertical plate 10. The fixing seat of the reducer 6 is fixed between the first vertical plate 9 and the second vertical plate 10 by passing bolts 13 through the mounting holes and inserting them into the screw holes.

[0038] It is understandable that the use of the screw hole and the bolt 13 structure can ensure that the connection between the reducer 6 fixing seat and the first vertical plate 9 and the second vertical plate 10 is firm. In addition, the screw hole and the bolt 13 connection method can fix the reducer 6 between the first vertical plate 9 and the second vertical plate 10, making the space utilization more compact and saving the assembly size. The design of fixing by the bolt 13 is convenient for future maintenance and replacement. The reducer 6 can be easily disassembled or replaced by removing the bolt 13, reducing the complexity and time cost of maintenance work.

[0039] In this embodiment, the left and right ends of the load-bearing crossbeam 8 extend downward to form hanging ears 14 , and the left and right ends of the support plate 11 are fixedly connected to the left and right hanging ears 14 .

[0040] In a preferred solution of the present embodiment, a hanging support rod 15 is connected between the left and right hanging ears 14 , and the hanging support rod 15 passes through the first vertical plate 9 and the second vertical plate 10 .

[0041] It can be understood that the provision of the suspension support rod 15 can effectively increase the connection stability between the load-bearing beam 8, the support plate 11, and the first vertical plate 9 and the second vertical plate 10, and prevent loosening or falling off due to vibration or external force during use.

[0042] In a preferred solution of the present embodiment, a plurality of support columns 16 are provided between the first vertical plate 9 and the second vertical plate 10 , one end of the support column 16 is fixedly connected to the first vertical plate 9 , and the other end of the support column 16 is fixedly connected to the second vertical plate 10 .

[0043] It is understandable that the provision of the support column 16 can effectively increase the support points between the first vertical plate 9 and the second vertical plate 10, increase the overall rigidity of the structure, and make the structure less likely to deform when subjected to force, thereby enhancing the stability of the entire structure and preventing the first vertical plate 9 and the second vertical plate 10 from shaking or deforming during use. The support column 16 can help evenly distribute the force carried to each support point, reduce excessive local force, and thus extend the service life of the structure.

[0044] In this embodiment, a buckle 17 is provided on the top of the load-bearing beam 8 for fixing the position of the elevator chassis.

[0045] In addition, if Figure 2 As shown, a lifting control circuit board 18 and a power control module 19 are also provided inside the lift chassis.

[0046] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which are all protected by the utility model.
