Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to a pre-tightening installation structure for a shaft sealing plate in a sightseeing elevator. Background Technology

[0002] Sightseeing elevators are widely used in modern architecture due to their transparent and aesthetically pleasing visual characteristics. Decorative panels are typically installed inside the elevator shaft to conceal internal components such as guide rails and cables, enhancing the visual experience during elevator operation.

[0003] However, existing platform sightseeing elevator shaft sealing plate installation structures generally adopt a discrete rigid bracket connection method, which prevents the sealing plates from being connected to the surrounding walls and can only be fixed through the top and bottom. This installation method has the following technical drawbacks:

[0004] First, because the elevator car is in a dynamic state during operation, especially during acceleration and deceleration, the shaft sealing plate is affected by the disturbance from the airflow in the car and the vibration transmitted by the building structure itself. The overall strength of the discrete rigid support connection structure is insufficient and the deformation resistance is poor. The sealing plate is prone to obvious low-frequency shaking or high-frequency vibration, which affects the riding experience and brings safety hazards.

[0005] Secondly, if the sealing plate shakes or shifts, it is easy for it to come into contact with and rub against the running car and car frame, resulting in scratches and paint wear on the sealing plate surface or the outer wall of the car. At the same time, it will generate abnormal noise, affecting the elevator's operating quality and even posing a safety risk in severe cases.

[0006] Therefore, there is an urgent need for a new type of installation structure that can achieve overall pre-tightening and stable positioning of the sealing plate installation system from a mechanical perspective, so as to solve the three major technical drawbacks of insufficient strength, shaking and friction noise at the same time. Summary of the Invention

[0007] The purpose of this invention is to address the problems in the existing sealing plate installation structure, which suffers from insufficient overall structural strength, easy shaking, and subsequent friction with the car frame and abnormal noise due to the use of discrete rigid brackets. This invention provides a pre-tightening installation structure for the shaft sealing plate of a sightseeing elevator.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a pre-tightening installation structure for a sightseeing elevator shaft sealing plate, comprising:

[0009] The guide rail base has a lower support assembly.

[0010] The machine beam is equipped with an upper support assembly, and a car guide rail is provided between the guide rail base and the machine beam.

[0011] The first pre-tightening installation assembly and the second pre-tightening installation assembly are respectively fitted and connected at both ends to the lower support assembly and the upper support assembly, and several well deck decorative sealing plates are pre-tightly assembled on the first pre-tightening installation assembly and the second pre-tightening installation assembly.

[0012] As a further description of the above technical solution:

[0013] The first pre-tightening installation assembly is located in the center of the guide rail base and the machine support beam. It includes a first bracket and a first steel wire rope. The first bracket is an angle steel, and two sets are arranged above and below it. It is respectively mounted and fixed on the lower bracket assembly and the upper bracket assembly on one side. The mounting hole on the other side is provided with a first long bolt. The middle part of the first long bolt is abutted and clamped to the first bracket by a screwed nut. Its end is connected to the first steel wire rope lock head. The first steel wire rope lock head is fixedly connected to the end of the first steel wire rope.

[0014] As a further description of the above technical solution:

[0015] The first long bolt is screwed into the connecting hole at the end of the first wire rope lock head to achieve reliable fixing of the wire rope end and adjustment of preload.

[0016] As a further description of the above technical solution:

[0017] The well deck decorative cover is provided with a through hole, through which a cable tie passes and is tied to the first steel wire rope, thereby achieving flexible binding and positioning of the well deck decorative cover and the central steel wire rope.

[0018] As a further description of the above technical solution:

[0019] The second pre-tightening installation component is located on the edge of the guide rail base and the machine support beam, and includes a profile. The two ends of the profile are respectively assembled onto the lower support assembly and the upper support assembly by fasteners.

[0020] As a further description of the above technical solution:

[0021] The second pre-tightening installation assembly also includes a second steel wire rope and a second bracket. The second steel wire rope passes through the through hole of the profile. The second bracket is an angle steel, which is arranged in pairs and fixed on one side of the lower bracket assembly and the upper bracket assembly respectively. The mounting hole on the other side is provided with a second long bolt. The middle part of the second long bolt is abutted and clamped to the second bracket by a screwed nut. Its end is connected to the second steel wire rope lock head. The second steel wire rope lock head is fixedly connected to the end of the second steel wire rope.

[0022] As a further description of the above technical solution:

[0023] The second long bolt is screwed into the connecting hole at the end of the second wire rope lock head to achieve reliable fixing of the wire rope end and adjustment of preload.

[0024] As a further description of the above technical solution:

[0025] The lower support assembly and / or upper support assembly are also equipped with limiting tooth plates. The end of the profile abuts against the limiting tooth plate, and the second wire rope passes through the tooth groove of the limiting tooth plate. By setting the limiting tooth plate, the end of the profile can be reliably limited to prevent it from shifting under vibration conditions, and the path of the second wire rope can be constrained and guided to ensure that the wire rope runs neatly during tensioning, further improving the stability of the overall structure.

[0026] As a further description of the above technical solution:

[0027] The well deck decorative cover is also provided with strip holes. Fasteners pass through the strip holes and are assembled and connected with the profile to achieve a reliable connection between the well deck decorative cover and the profile and to fine-tune the installation position.

[0028] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0029] This invention utilizes steel wire rope as a flexible connection and tensioning element, combined with profile arrangement and tensioning design, to achieve overall pre-tensioning and stable positioning of the sealing plate installation system from a mechanical perspective. The mating structure of the long bolt and the steel wire rope lock head allows for convenient adjustment of the steel wire rope tension, compensating for installation errors caused by unevenness in the wellbore installation benchmark, and enabling readjustment of the pre-tension force after long-term use to ensure continuous stability. The setting of the limiting tooth plate further improves the reliability of profile end positioning and the regularity of steel wire rope routing, enhancing the overall structure's vibration resistance under dynamic working conditions.

[0044] Example 1:

[0045] Please see Figure 1-6 The present invention provides a technical solution: a pre-tightening installation structure for a sightseeing elevator shaft sealing plate, mainly including a guide rail base 1, a machine support beam 3, a first pre-tightening installation component 5, and a second pre-tightening installation component 6.

[0046] The guide rail base 1 is fixedly installed on the ground at the bottom of the elevator shaft, and a lower support assembly 2 is installed above it. The machine support beam 3 is installed at the top of the shaft, and an upper support assembly 4 is installed below it. A car guide rail is installed between the guide rail base 1 and the machine support beam 3, and the car moves up and down along the car guide rail.

[0047] Both the upper support assembly 4 and the lower support assembly 2 are frame structures used to support and position the first pre-tightening installation assembly 5 and the second pre-tightening installation assembly 6.

[0048] The first pre-tensioning installation assembly 5 is located at the center of the guide rail base 1 and the machine support beam 3, and includes a first bracket 8 and a first wire rope 9. The first bracket 8 is made of angle steel, and one set is set at the top and one at the bottom. One side of the upper first bracket 8 is fixed to the upper bracket assembly 4 by bolts, and one side of the lower first bracket 8 is fixed to the lower bracket assembly 2 by bolts. The other side of the first bracket 8 is machined with an assembly hole, and a first long bolt 10 is inserted into the assembly hole. A nut is screwed onto the middle of the first long bolt 10, and the nut is located on the end face of the first bracket 8. By tightening the nut, the first long bolt 10 can be abutted and clamped to the first bracket 8. The end of the first long bolt 10 is screwed into the connecting hole at the end of the first wire rope lock head 11. The other end of the first wire rope lock head 11 is fixedly connected to the end of the first wire rope 9. During installation, by rotating the nut on the first long bolt 10 with a wrench, the first wire rope lock head 11 can be pulled to move along the axial direction of the first long bolt 10, thereby adjusting the tension of the first wire rope 9.

[0049] The second pre-tightening mounting assembly 6 is located on both sides of the edge of the guide rail base 1 and the machine support beam 3, and includes a profile 14, a second steel wire rope 15, and a second bracket 16. The profile 14 is preferably an aluminum alloy profile, with its two ends respectively mounted to the lower bracket assembly 2 and the upper bracket assembly 4 using fasteners such as T-bolts. The profile 14 has through holes 17 machined along its length, through which the second steel wire rope 15 passes and runs the entire length of the profile 14. The second bracket 16 is made of angle steel and is arranged in pairs, one above the other. One side of the upper second bracket 16 is bolted to the upper bracket assembly 4, and one side of the lower second bracket 16 is bolted to the lower bracket assembly 2. The other side of the second bracket 16 has a mounting hole, into which a second long bolt 18 is inserted. A nut is screwed onto the middle of the second long bolt 18, which abuts against and clamps the second bracket 16 for positioning. The end of the second long bolt 18 is screwed into the connecting hole at the end of the second wire rope lock head 19, and the other end of the second wire rope lock head 19 is fixedly connected to the end of the second wire rope 15. The tension of the second wire rope 15 can be adjusted by rotating the nut on the second long bolt 18.

[0050] Specifically, the hoistway decorative cover 7 consists of multiple panels arranged sequentially from bottom to top along the height of the hoistway. The upper and lower edges of the hoistway decorative cover 7 are machined with slotted holes 21. T-bolts and other fasteners pass through these slotted holes 21 and assemble with grooves on the surface of the profile 14, thus fixing the hoistway decorative cover 7 to the profile 14. Since the slotted holes 21 have a certain length allowance, the vertical position of the hoistway decorative cover 7 can be adjusted appropriately during installation to compensate for installation errors. Simultaneously, a through hole 12 is machined in the center of the hoistway decorative cover 7. Cable ties 13 pass through the through hole 12 and are tied to the first steel wire rope 9, achieving a flexible connection between the hoistway decorative cover 7 and the first steel wire rope 9.

[0051] During installation, the hoistway decorative sealing plate 7 is first initially fixed to the profile 14 using fasteners. Then, the nuts on the first long bolt 10 and the second long bolt 18 are rotated to tighten the first wire rope 9 and the second wire rope 15 respectively, so that the entire sealing plate system forms a stable overall structure under the pre-tension of the wire ropes. Under the dual action of the rigid support of the profile 14 and the flexible pre-tension of the first wire rope 9, the hoistway decorative sealing plate 7 can effectively resist the airflow disturbance and vibration excitation generated during elevator operation, avoiding the occurrence of low-frequency shaking and high-frequency vibration.

[0052] This invention utilizes steel wire rope as a flexible connection and tensioning element. Combined with the profile arrangement and tensioning design, the well deck decorative sealing plate 7 achieves rigid support while also being subjected to pre-tensioning force from the central and edge steel wire ropes. The entire sealing plate system forms a stable pre-tensioning force system, eliminating technical drawbacks caused by insufficient strength, swaying, and frictional noise from a fundamental mechanical perspective. Simultaneously, the long bolt and nut mating structure allows for convenient adjustment of the steel wire rope tension, compensating for errors caused by uneven well deck installation benchmarks. Furthermore, the pre-tensioning force can be readjusted after long-term use, ensuring long-term structural stability and reliability.

[0053] Example 2:

[0054] Please see Figure 1 , 3 Figure 6 shows a pre-tightening installation structure for a sightseeing elevator shaft sealing plate according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: In this embodiment, a limiting toothed plate 20 is also assembled on the lower support assembly 2. The limiting toothed plate 20 is fixed to the lower support assembly 2 by bolts, and the lower end of the profile 14 abuts against the upper surface of the limiting toothed plate 20, thereby reliably limiting the lower end of the profile 14 and preventing it from shifting under vibration conditions.

[0055] Meanwhile, the limiting toothed plate 20 is machined with toothed grooves. The second wire rope 15 passes through the toothed grooves of the limiting toothed plate 20. The toothed grooves constrain and guide the passage path of the second wire rope 15, ensuring that the wire rope runs neatly during tensioning and preventing interference between the wire rope and other components. It can be understood that the limiting toothed plate 20 can be set only on the upper support assembly 4, or simultaneously on the lower support assembly 2 and the upper support assembly 4, both of which can achieve the functions of limiting the end of the profile 14 and guiding the second wire rope 15. Similarly, the limiting toothed plate 20 can also be set at the first wire rope 9 to achieve the limiting effect on it. In this embodiment, the profile 14 can be made by connecting multiple short profiles into a complete long profile according to the shaft height to meet the installation requirements of different heights.

[0056] The setting of the limiting tooth plate 20 further enhances the reliability of the profile end positioning and the regularity of the wire rope routing, and improves the overall structure's vibration resistance and service life under dynamic working conditions.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
