[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 9 The present invention provides a technical solution: a slidable earthquake-resistant corridor structure of an elevator shaft, comprising a corridor body arranged between a shaft body 1 and an existing building 2, the corridor body being composed of a horizontal base beam 9 and a co-located cross beam 10, and a flat sealing structure for sealing the horizontal surface of the corridor body being provided on the horizontal base beam 9; The flat sealing structure comprises a plurality of transverse sealing plates 11 arranged on a horizontal base beam 9. The plurality of transverse sealing plates 11 are arranged on the horizontal base beam 9 in parallel and equidistantly in an initial state. The horizontal base beam 9 is provided with a transverse flip assembly for driving the plurality of transverse sealing plates 11 to move horizontally synchronously and deflect in the same direction. The end of the co-located cross beam 10 away from the horizontal base beam 9 is fixedly connected to an anchor bolt 7, and a fixed assembly for supporting and fixing the anchor bolt 7 and allowing the anchor bolt 7 to slide horizontally is provided on the well body 1; The co-located cross beam 10 is horizontally slidably arranged on the horizontal base beam 9 , and a positioning component for limiting the horizontal position of the co-located cross beam 10 is provided on the horizontal base beam 9 .

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, when constructing a corridor for connecting the well body 1 and the existing building 2, the horizontal base beam 9 and the co-located cross beam 10 are hoisted to the set installation position, wherein the horizontal base beam 9 and the co-located cross beam 10 are slidingly arranged, and thus during the hoisting process, the overall length is less than the designed corridor length. Therefore, it can be suitable for construction in narrow spaces and complex environments such as old residential areas, and through the horizontal flip assembly, multiple groups of horizontal sealing plates 11 can be driven to move synchronously in the horizontal direction and deflect in the same direction until the multiple groups of horizontal sealing plates 11 are parallel to the horizontal base beam 9, and the multiple groups of horizontal sealing plates 11 can be driven to block the horizontal planes of the horizontal base beam 9 and the co-located cross beam 10 in a flat state, and can be used as the bottom plate of the corridor.

[0022] At the same time, when constructing the corridor, when the horizontal base beam 9 and the co-located cross beam 10 are hoisted to the designed installation position, the horizontal base beam 9 is installed first so that the horizontal base beam 9 can be fixedly connected to the existing building 2, and then the multiple groups of transverse sealing plates 11 are driven to move horizontally and deflect through the transverse flip assembly, and then the horizontal movement of the transverse sealing plates 11 drives the co-located cross beam 10 to slide on the horizontal base beam 9, so that the co-located cross beam 10 can move toward the direction of the transverse sealing plates 11.

[0023] Among them, when the horizontal sealing plate 11 is in a flat state, the co-located crossbeam 10 is installed by driving the fixed assembly, so that the co-located crossbeam 10 can be slidably installed on the well body 1, thereby effectively avoiding stress concentration or displacement problems caused by long-term use or environmental changes, thereby reducing the risk of structural aging or damage, thereby extending the service life of the well body 1 and the corridor, and reducing the subsequent maintenance costs and the frequency of engineering repairs.

[0024] It should be noted that during the actual installation of the corridor, during the hoisting process, due to the limitation of the positioning components, the overlapping length of the horizontal base beam 9 and the co-located cross beam 10 is the largest, that is, the length of the horizontal base beam 9 and the co-located cross beam 10 together is smaller, and thus the space occupied during the hoisting process is smaller. Therefore, it can adapt to the renovation of buildings with limited space and reduce the inconvenience caused by space limitations to the corridor construction.

[0025] Among them, in order to ensure the flatness of the horizontal surface of the corridor, multiple groups of the horizontal sealing plates 11 are synchronously arranged horizontally in a flat state, and the upper surfaces of the multiple groups of horizontal sealing plates 11 are at the same horizontal height. In actual use, when the multiple groups of horizontal sealing plates 11 are in a flat state driven by the horizontal flip assembly, they can be used as the horizontal paving surface of the internal space of the corridor, and then there is no need to pave the horizontal supporting surface of the corridor channel additionally, thereby reducing the construction process to improve the construction efficiency.

[0026] At the same time, by relatively setting the horizontal base beams 9 and the co-located cross beams 10, and making the vertical spacing between the two relatively set groups of horizontal base beams 9 and co-located cross beams 10 the design height of the corridor, when installing the corridor, the lower group of horizontal base beams 9 and co-located cross beams 10 and the multiple groups of horizontal sealing plates 11 arranged thereon can serve as the horizontal lower surface support of the corridor, and the other upper group of horizontal base beams 9, co-located cross beams 10 and the multiple groups of horizontal sealing plates 11 can serve as the horizontal upper surface of the corridor, thereby realizing the installation process of the horizontal support surface and the top plate of the corridor.

[0027] In one of the more preferred embodiments, the fixed assembly includes a horizontal steel beam 3 fixedly connected to the well body 1, and an inclined support 5 is provided on the horizontal steel beam 3. The inclined support 5 is inclinedly arranged and its two ends are respectively fixedly connected to the well body 1 and the horizontal steel beam 3; The cross steel beam 3 is fixedly connected with a rubber pad 4, and both the cross steel beam 3 and the rubber pad 4 are provided with a strip-shaped through hole 6 for the anchor bolt 7 to slide through; A corbel steel plate 8 is bolted to one end of the horizontal base beam 9 away from the co-located cross beam 10 , and the corbel steel plate 8 is bolted to the existing building 2 .

[0028] like Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, a corbel steel plate 8 is provided between the horizontal base beam 9 and the existing building 2, and the corbel steel plate 8 is bolted to the horizontal base beam 9 and the existing building 2, respectively, so as to achieve the purpose of installing and fixing the horizontal base beam 9 (such as Figure 8 As shown), the transverse flip assembly is subsequently used to drive multiple groups of transverse sealing plates 11 to move horizontally and deflect synchronously, and the horizontal movement of the transverse sealing plates 11 drives the co-located crossbeams 10 to move horizontally toward the transverse sealing plates 11, so that the co-located crossbeams 10 can be placed on the rubber pads 4.

[0029] At the same time, by fixing the anchor bolts 7 on the transverse steel beam 3, and sliding the anchor bolts 7 through the strip through holes 6 to penetrate the rubber pads 4 and the transverse steel beam 3, and clamping the anchor bolts 7 through nuts and other components, the anchor bolts 7 can be prevented from being separated from the transverse steel beam 3, wherein the rubber pad 4 is arranged between the transverse steel beam 3 and the co-located transverse beam 10 to prevent damage to the existing building 2 when a settlement difference occurs between the well body 1 and the existing building 2.

[0030] During the actual installation process, the anchor bolts 7 only need to be installed on the horizontal steel beam 3 through the strip through holes 6. Therefore, a certain error in the horizontal direction can be allowed during installation, and the construction requirements are low. There is no need for precise calibration, which can further improve the installation efficiency.

[0031] On the basis of the fixed assembly embodiment, the transverse flip assembly includes a side gear 12 driven by a motor and freely rotating in the vertical direction, the side gear 12 is fixedly rotated on the horizontal base beam 9, and a plurality of fixed support assemblies for supporting the transverse sealing plates 11 and corresponding to the plurality of transverse sealing plates 11 are arranged on the side of the side gear 12 facing the same position transverse beam 10; The fixed support assembly includes a main stage gear 13, a left connecting rod 14 is coaxially fixed on the main stage gear 13, a right connecting rod 15 is fixedly rotated on one end of the left connecting rod 14 away from the main stage gear 13, and a secondary gear 16 is coaxially fixed on one end of the right connecting rod 15 away from the left connecting rod 14; The horizontal base beam 9 is provided with a plurality of sets of equidistantly arranged horizontal sliding seats 18, and the plurality of sets of horizontal sliding seats 18 are slidably arranged on the horizontal base beam 9 and the horizontal beam 10 at the same position, and the main stage gear 13 in the fixed support assembly close to the side of the side gear 12 is meshedly connected with the side gear 12; The primary gears 13 and secondary gears 16 in two adjacent groups of the fixed support assemblies are meshed and connected and are fixedly rotated on the horizontal sliding seat 18; The side gears 12 and the secondary gears 16 in the multiple groups of fixed support assemblies are coaxially fixed with oblique mounting seats 17, and the multiple groups of oblique mounting seats 17 are correspondingly arranged with the multiple groups of transverse sealing plates 11, and the oblique mounting seats 17 and the transverse sealing plates 11 are fixedly connected.

[0032] The horizontal sliding seat 18 includes an inner convex portion 19 and an outer convex portion 20 formed in one piece. A main sliding groove 21 for the inner convex portion 19 to slide horizontally is provided on the horizontal base beam 9, and a secondary sliding groove 22 for the outer convex portion 20 to slide horizontally is provided on the same horizontal beam 10. The horizontal base beam 9 is provided with a groove body 1 for the horizontal sliding of the co-located cross beam 10.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the side gear 12 is driven by a motor to rotate freely on the horizontal base beam 9, thereby driving the main gear 13 in the closest group of fixed support components to rotate through the side gear 12, wherein a left connecting rod 14 is coaxially arranged on the main gear 13, and a right connecting rod 15 is coaxially arranged on the secondary gear 16, and the left connecting rod 14 and the right connecting rod 15 are rotatably arranged. Therefore, when the main gear 13 in the fixed support component rotates, the right connecting rod 15 and the secondary gear 16 can be driven to rotate synchronously through the left connecting rod 14.

[0034] Among them, the main stage gear 13 and the secondary gear 16 in the adjacent fixed support assemblies are meshingly connected. Therefore, the purpose of driving multiple groups of fixed support assemblies to run synchronously can be achieved through the movement process of a group of fixed support assemblies closest to the edge gear 12. The main stage gear 13 and the secondary gear 16 in meshing state in two adjacent groups of fixed support assemblies are all fixedly arranged on the same group of transverse sliding seats 18. Therefore, when multiple groups of fixed support assemblies move synchronously, multiple groups of transverse sliding seats 18 can be driven to move synchronously in the horizontal direction.

[0035] At the same time, in the initial state, the co-positioned crossbeam 10 is restricted by the positioning assembly and cannot separate from the horizontal base beam 9, but with the rotation of the side gear 12, the horizontal base beam 9 can release the restriction on the co-positioned crossbeam 10. At the same time, with the horizontal movement of multiple sets of transverse sliding seats 18, the transverse sliding seats 18 at the end can push the co-positioned crossbeam 10 to drive the co-positioned crossbeam 10 to gradually move away from the horizontal base beam 9.

[0036] It should be noted that the transverse sliding seat 18 is slidably set on the horizontal base beam 9 through the main sliding groove 21, and the transverse sliding seat 18 can be slidably set on the co-positioned crossbeam 10 through the secondary sliding groove 22. Therefore, when horizontal relative movement occurs between the co-positioned crossbeam 10 and the horizontal base beam 9, the horizontal base beam 9 or the co-positioned crossbeam 10 can support the corresponding transverse sliding seat 18 thereon to ensure the stability of the transverse sliding seat 18 during horizontal movement.

[0037] On the basis of the embodiment of the transverse flip assembly, the positioning assembly includes a Z-shaped frame 23 fixedly connected to the horizontal base beam 9, a limit pin 25 is slidably passed through the Z-shaped frame 23, a rectangular block 24 is fixedly connected to the side of the co-positioned cross beam 10 facing the limit pin 25, and a circular hole for accommodating the limit pin 25 is opened on the rectangular block 24; The outer ring of the limiting pin 25 is sleeved with a pressure spring 26 , and the two ends of the pressure spring 26 are fixedly connected to the limiting pin 25 and the Z-shaped frame 23 respectively.

[0038] The Z-shaped frame 23 is provided with a cam 28 which can rotate freely in the vertical direction and is transmission-connected to the side gear 12. The cam 28 rotates on the Z-shaped frame 23 on a fixed axis. An end plate 27 is coaxially fixed to the end of the limit pin 25 away from the rectangular block 24. The cam 28 and the end plate 27 are alternately arranged, and the outer peripheral surface of the cam 28 is in contact with the end plate 27.

[0039] like Figure 4 and Figure 5 As shown, when the side gear 12 rotates in the vertical direction, it can drive the cam 28 connected to it to rotate synchronously, wherein both the cam 28 and the side gear 12 can be driven by multiple sets of bevel gear meshing to ensure that the cam 28 can rotate synchronously with the side gear 12.

[0040] Among them, when the cam 28 rotates, it can push the end plate 27 that is in contact with it to move in the horizontal direction, thereby driving the limit pin 25 to slide on the Z-shaped frame 23, and driving the pressure spring 26 to deform, so as to drive the limit pin 25 to disengage from the circular hole opened on the rectangular block 24, thereby releasing the restriction on the co-positioned crossbeam 10, so that when the horizontal sliding seat 18 moves in the horizontal direction to contact the co-positioned crossbeam 10, it can push the co-positioned crossbeam 10 to slide on the horizontal base beam 9, so as to drive the co-positioned crossbeam 10 to move toward the well body 1, until the multiple groups of horizontal sealing plates 11 are in a flat state, and the co-positioned crossbeam 10 can correspond to the horizontal steel beam 3.

[0041] In order to ensure the stability of multiple groups of transverse sealing plates 11 in a flat state, pin plates 30 are bolted to the multiple groups of transverse sealing plates 11, and leveling grooves 29 for accommodating adjacent pin plates 30 are opened on the transverse sealing plates 11. When the multiple groups of transverse sealing plates 11 are in a flat state, pin plates 30 are set at the junction of two groups of transverse sealing plates 11, and the pin plates 30 are bolted to the two groups of transverse sealing plates 11 to ensure that the multiple groups of transverse sealing plates 11 form a complete and uninterrupted paving surface, and leveling grooves 29 corresponding to the pin plates 30 are set on the transverse sealing plates 11 to ensure that when two adjacent groups of transverse sealing plates 11 are fixed by the pin plates 30, the upper surfaces of the pin plates 30 and the transverse sealing plates 11 can be ensured to be at the same height to avoid height difference affecting the flatness of the corridor channel.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
