For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0026] Example 1 See also Figures 1 to 7 The present invention provides a telescopically adjustable multifunctional elevator shaft operating platform, comprising a vertical bracket 1, an oblique bracket 2 rotatably arranged at the lower end of the vertical bracket 1, and the upper ends of the vertical bracket 1 and the oblique bracket 2 are both rotatably connected to a platform plate 3; Two sets of leveling components 4 for leveling the platform plate 3 are fixedly arranged on the plate body of the platform plate 3; A supporting bracket 5 is provided at the lower end of the vertical bracket 1 , and the supporting bracket 5 is linked with the oblique bracket 2 via a linkage mechanism 6 .

[0027] The vertical support 1 includes two parallel vertical poles 7, and the two vertical poles 7 are fixedly connected by a plurality of horizontal poles; A push rod 8 is slidably disposed at the upper end of each upright rod 7, and the upper end of the push rod 8 is rotatably connected to the platform plate 3; The upper end of the vertical rod 7 is respectively provided with a plurality of positioning holes, and the lower end of the top rod 8 is provided with a plurality of limiting holes, and the vertical rod 7 and the top rod 8 are fixedly connected by a plurality of bolts; Since the heights of different floors are different, this can be achieved by adjusting the position of the top rod 8 on the vertical rod 7. First, loosen the bolts fixing the top rod 8 and the vertical rod 7, and then slide the top rod 8 up or down as needed. After adjusting to a suitable height, align the positioning hole on the vertical rod 7 with the limiting hole at the lower end of the top rod 8 again and fix it with bolts; During the height adjustment process, it is important to ensure that the heights of the top rods 8 on both sides are adjusted to be consistent to ensure that the platform plate 3 remains horizontal. A notch 9 is formed at the lower end of the vertical rod 7 , and the notch 9 faces away from the oblique bracket 2 . The supporting corbel 5 is rotatably arranged in the notch 9 .

[0028] When the platform starts to move upward, due to the action of the linkage mechanism 6, the supporting corbel 5 will be stored in the slot 9 to prevent the supporting corbel 5 from colliding with the wall or the upper floor. When the device is in use, the supporting corbel 5 can extend out of the slot 9 to allow the supporting corbel 5 to fall on the floor panel of the next layer.

[0029] The oblique support 2 includes two parallel oblique rods 10, the two oblique rods 10 are fixedly connected by a plurality of connecting rods, and the lower end of each oblique rod 10 is rotatably connected to the lower end of the vertical support 1; A support rod 11 is slidably disposed at the upper end of each inclined rod 10, and the upper end of the support rod 11 is rotatably connected to the platform plate 3; A plurality of through holes are arranged in an array at the upper end of each inclined rod 10, wherein a bolt is arranged in each of several adjacent through holes; A slide groove 12 is provided at the lower end of the support rod 11 , and the bolt slides in the slide groove 12 .

[0030] Adjust the protruding length of the support rod 11 on the oblique rod 10 according to actual needs, and determine the installation position of the screw according to the position of the support rod 11, so that when the platform plate 3 is in a horizontal state, the bolt is located at the uppermost end of the slide groove 12. When the device is hoisted, first lift the end of the platform plate 3 connected to the oblique bracket 2. Under the action of the slide groove 12, the bolt is at the lower end of the slide groove 12. At this time, the platform plate 3 is placed at an angle, which reduces the projection area of ​​the platform plate 3 and makes it easier to perform hoisting operations in a relatively narrow elevator shaft space, thereby avoiding collision between the platform plate 3 and the side wall of the elevator shaft during hoisting.

[0031] The linkage mechanism 6 includes a connecting rod 13 rotatably disposed at the lower end of the inclined rod 10, one end of the connecting rod 13 is rotatably connected to the inclined rod 10, and the other end is slidably connected to the vertical bracket 1; A guide groove 14 is provided on the vertical bracket 1, and one end of the connecting rod 13 slides in the guide groove 14; One end of the connecting rod 13 sliding in the guide groove 14 is rotatably provided with a support rod 15 , and a movable end of the support rod 15 is rotatably connected to the middle part of the supporting corbel 5 .

[0032] When the device is hoisted, first lift the side of the platform plate 3 connected to the oblique bracket 2. At this time, the oblique bracket 2 is inclined to the side close to the vertical bracket 1. During the rotation of the oblique bracket 2, the connecting rod 13 is driven to move, so that the movable end of the connecting rod 13 moves from the upper end of the guide groove 14 to the lower end of the guide groove 14. During the movement of the connecting rod 13, the support bracket 5 is moved from a horizontal state to a vertical state through the action of the strut 15, and the support bracket 5 is stored in the groove 9. Then the platform plate 3 is hoisted as a whole to the upper floor.

[0033] After the device is hoisted to the upper floor, it is continuously hoisted upward for a certain distance until the horizontal height of the lower end of the supporting corbel 5 is higher than the horizontal height of the lower floor slab, and then the platform and one side of the oblique bracket 2 are slowly lowered. At this time, the oblique bracket 2 is tilted to the side away from the vertical bracket 1. During the rotation of the oblique bracket 2, the connecting rod 13 is driven to move, so that the movable end of the connecting rod 13 moves from the lower end of the guide groove 14 to the upper end of the guide groove 14. During the movement of the connecting rod 13, the supporting corbel 5 is moved from the vertical state to the horizontal state through the action of the strut 15, and the supporting corbel 5 extends to the outside of the vertical bracket 1. Then the device is lowered as a whole until the supporting corbel 5 is against the lower floor slab, so as to support the lower floor slab. Since one end of the support rod 15 is rotatably connected to the supporting corbel 5 and the other end is abutted against the upper end of the guide groove 14, when the device is used, the support rod 15 can keep the supporting corbel 5 in a stable horizontal extension state at all times, providing reliable lateral support force for the platform, which can effectively disperse the load borne by the platform and ensure the stability and safety of the platform during the construction process.

[0034] When construction workers are working on the platform, whether they are walking or piling materials, the supporting bracket 5 can evenly transfer the force to the lower floor slab through the linkage structure of the support rod 15 and the connecting rod 13, thereby preventing the platform from tilting or shaking. At the same time, this design also makes the platform more flexible and convenient during installation and adjustment. Operators can quickly realize the positioning of the platform and the state conversion of the supporting bracket 5 through lifting and lowering operations according to actual construction needs, thereby improving construction efficiency and reducing construction risks.

[0035] Furthermore, a protrusion is provided at the lower end of the slot 9, which enables the supporting corbel 5 to be received in the slot 9 in a slightly inclined state, thereby avoiding the occurrence of a dead point position; when the supporting corbel 5 is in this inclined state, it can be received in the slot 9 during the lifting process; at the same time, this inclined setting is also beneficial when the platform is lowered for installation, so that the supporting corbel 5 can be more smoothly rotated out of the slot 9 and unfolded to the working position.

[0036] The leveling assembly 4 includes a base 16 fixedly arranged on the platform plate 3, a handle 17 is rotatably arranged at one end of the base 16, and a push rod 18 is slidably arranged at the other end, and the push rod 18 is connected to the handle 17 via a pull rod 19; A grip cover is provided at one end of the handle 17 away from the base 16; A push plate 20 is fixedly disposed at one end of the push rod 18 away from the handle 17 .

[0037] When the device is in the working position, since the device is supported only by the supporting bracket 5 and the lower platform, the platform plate 3 is in an inclined state, specifically, the side where the platform plate 3 is connected to the oblique bracket 2 is the low horizontal end, therefore, the leveling component 4 is arranged on the side close to the connection between the platform plate 3 and the oblique bracket 2; The user turns the handle 17, and the handle 17 drives the push rod 18 to move to the side away from the platform plate 3 under the action of the pull rod 19. The push plate 20 at the end of the push rod 18 moves toward the wall of the elevator shaft and applies a thrust as the push rod 18 moves, until the push rod 18 is fully extended. At this time, the inclination of the platform plate 3 is significantly reduced and close to a horizontal state. A lock hook 21 is rotatably arranged in the middle of the handle 17 , and a lock slot detachably connected to the lock hook 21 is provided on the base 16 . When the pull rod 19 is flush with the push rod 18 , the lock hook 21 is fixedly connected to the base 16 .

[0038] A rubber sleeve is fixedly provided at one end of the lock hook 21 away from the base 16 , and a torsion spring is provided between the lock hook 21 and the handle 17 , so that the lock hook 21 can be automatically inserted into the lock slot of the base 16 when the handle 17 is in use.

[0039] When the platform board 3 is leveled, the handle 17 needs to be locked in the current position to keep the platform in a stable horizontal state. When the pull rod 19 is flush with the push rod 18, the lock hook 21 can automatically rotate and insert into the lock slot on the base 16. Without applying external force, the leveling component 4 can be kept stable for use. When construction workers are working on the platform, the platform board 3 can remain stable regardless of the movement of workers or the stacking of materials.

[0040] When the device needs to be lifted, the leveling assembly 4 is first unlocked. The operator holds the handle 17 with his hand away from the base 16, and pinches the end of the lock hook 21 away from the base 16 with his fingers, that is, the part with the rubber sleeve. The rubber sleeve can provide a good grip and can play an anti-slip role. After the fingers pinch the rubber sleeve, the lock hook 21 can be unlocked from the lock groove. At this time, the user can move the push rod 18 to the side of the platform plate 3 by turning the handle 17.

[0041] The platform plate 3 is a rectangular or square steel frame welded by a number of platform longitudinal beams and platform cross beams, and the sizes of the platform longitudinal beams and platform cross beams are set according to the shape and size of the elevator shaft opening; The upper ends of the vertical bracket 1 and the oblique bracket 2 are both rotatably connected to the steel frame of the platform plate 3; Steel plates are laid and welded on the upper surface of the steel frame according to the size of the steel frame. The steel plate is provided with lifting ears 22, which are distributed at the four corners of the steel plate.

[0042] When the present invention is used, when the device is hoisted, first lift the side of the platform plate 3 connected to the oblique bracket 2. At this time, the oblique bracket 2 is inclined to the side close to the vertical bracket 1. During the rotation of the oblique bracket 2, the connecting rod 13 is driven to move, so that the movable end of the connecting rod 13 moves from the upper end of the guide groove 14 to the lower end of the guide groove 14. During the movement of the connecting rod 13, the support bracket 5 is moved from a horizontal state to a vertical state through the action of the strut 15, and the support bracket 5 is stored in the slot 9. Then the platform plate 3 is hoisted as a whole to the upper floor.

[0043] After the device is hoisted to the upper floor, it is continuously hoisted upward for a certain distance until the horizontal height of the lower end of the supporting corbel 5 is higher than the horizontal height of the lower floor slab, and then the platform and one side of the oblique bracket 2 are slowly lowered. At this time, the oblique bracket 2 is inclined to the side away from the vertical bracket 1. During the rotation of the oblique bracket 2, the connecting rod 13 is driven to move, so that the movable end of the connecting rod 13 moves from the lower end of the guide groove 14 to the upper end of the guide groove 14. During the movement of the connecting rod 13, the supporting corbel 5 is moved from a vertical state to a horizontal state through the action of the strut 15, and the supporting corbel 5 extends to the outside of the vertical bracket 1. Then the device is lowered as a whole until the supporting corbel 5 is against the lower floor slab, so as to support the lower floor slab.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
