Description

Technical Field

[0001] This utility model relates to the field of elevator construction technology, specifically a support component for elevator construction. Background Technology

[0002] During elevator construction, the supporting components used in elevator construction are key equipment to ensure construction safety and efficiency. They cover multiple supporting structures used in elevator shaft structure construction, equipment installation, and subsequent maintenance. The elevator shaft operating platform is one of the core components. The elevator shaft operating platform is mainly used to provide construction personnel with a stable working plane, making it convenient for them to carry out operations such as guide rail installation, cable laying, and shaft inner wall decoration inside the elevator shaft. It is an indispensable functional platform in the process of elevator construction from shaft excavation to equipment commissioning. In actual construction scenarios, the elevator shaft operating platform needs to be placed inside the elevator shaft. In order to ensure that the platform can be smoothly placed into the elevator shaft and complete the initial positioning, the overall size of the platform needs to be slightly smaller than the internal size of the elevator shaft, that is, there will be a certain gap between the platform and the inner wall of the elevator shaft. However, existing elevator shaft operating platforms are not tightly fitted to the inner wall of the elevator shaft. When construction workers move or place construction tools or materials on the platform, or when affected by factors such as slight external vibrations, the platform is prone to shaking or even displacement within the elevator shaft. This shaking and displacement not only affects the accuracy of construction but also frightens the workers, posing a serious threat to their personal safety. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a support component for elevator construction. This component has the advantage of being able to drive the inner wall clamping component to clamp the inner wall of the elevator shaft outward through an adjustment mechanism, eliminating the shaking caused by the gap between the platform and the shaft wall, improving platform stability, and ensuring construction safety and accuracy. To a certain extent, this improves or solves the problem of existing elevator shaft operating platforms. Because the platform and the inner wall of the elevator shaft are not tightly fitted, the platform is prone to shaking or even displacement within the elevator shaft when construction workers move or place construction tools or materials on the platform, or when affected by factors such as slight external vibrations. This shaking and displacement not only affects construction accuracy but also frightens the workers and poses a serious threat to their personal safety.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a support component for elevator construction, comprising a tripod body and a platform, wherein the platform is disposed at the top of the tripod body and is fixedly connected to the tripod body, a mounting groove is provided on the upper surface of the platform, an encapsulation plate is fixedly connected to the upper end of the mounting groove, the encapsulation plate is flush with the upper surface of the platform, and a stabilizing device is provided inside the mounting groove. The stabilizing device includes support rods, inner wall clamping assemblies, and an adjustment mechanism. There are two support rods, which are respectively located on the front and rear sides of the upper end of the placement groove, and their left and right ends are respectively fixedly connected to the left and right side surfaces of the placement groove. There are two inner wall clamping assemblies, which are respectively located on the left and right sides of the placement groove. The adjustment mechanism is located at the lower end of the two inner wall clamping assemblies.

[0005] In a preferred embodiment of this utility model, the inner wall support clamping assembly includes a movable plate, push rods, a clamping plate, and a pressure rod. The movable plate is sleeved on the right end surface of the two support rods and is slidably connected to the support rods. There are two push rods, which are respectively fixedly connected to the front and rear ends of the right surface of the movable plate. The right ends of the two push rods extend out of the platform and are slidably connected to the platform. The clamping plate is fixedly connected to one end of the two push rods that extends out of the platform. The pressure rod is fixedly connected to the lower surface of the movable plate.

[0006] As a preferred embodiment of this invention, several anti-slip cones are uniformly fixedly connected to the surfaces of the two clamping plates that are far apart from each other.

[0007] In a preferred embodiment of this invention, the adjusting mechanism includes a linkage component and a self-locking control component. The linkage component is disposed at the lower ends of the two pressure rods, and the self-locking control component is disposed on the left side of the lower end of the linkage component.

[0008] In a preferred embodiment of this utility model, the linkage component includes a rotating rod, a turntable, an arc-shaped extrusion groove, and a worm gear. The rotating rod is located at the center inside the placement groove, with its upper end rotatably connected to the encapsulation plate and its lower end rotatably connected to the bottom surface inside the placement groove. The turntable is sleeved on the surface of the rotating rod and is fixedly connected to the rotating rod. There are two arc-shaped extrusion grooves, which are respectively opened on the left and right sides of the turntable. The lower ends of the two pressure rods are respectively located inside the two arc-shaped extrusion grooves and are movably connected to the arc-shaped extrusion grooves. The worm gear is sleeved on the lower end surface of the rotating rod and is fixedly connected to the rotating rod. The platform has a rotating groove on its front surface.

[0009] In a preferred embodiment of this utility model, the self-locking control component includes a worm, a knob, and an internal hexagonal slot. The worm is located on the left side of the worm wheel and meshes with it. Both ends of the worm are rotatably connected to the platform, and the front end extends into the rotating slot. The knob is located inside the rotating slot and is fixedly connected to the front end of the worm. The internal hexagonal slot is formed on the front surface of the knob.

[0010] As a preferred embodiment of this invention, a plurality of anti-slip blocks are uniformly and fixedly connected to the upper surface of the encapsulation board.

Because the platform is not tightly fitted to the inner wall of the elevator shaft, when construction workers move or place construction tools or materials on the platform, or when affected by factors such as slight external vibrations, the platform is prone to shaking or even displacement within the elevator shaft. This shaking and displacement not only affects the construction accuracy but also frightens the workers, posing a serious threat to their personal safety.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] Example 1 Reference Figure 1-5 This is the first embodiment of the present utility model, which provides a support component for elevator construction, including a triangular frame 1 and a platform 2. The platform 2 is set at the top of the triangular frame 1 and is fixedly connected to the triangular frame 1. A mounting groove 21 is opened on the upper surface of the platform 2. An encapsulation plate 22 is fixedly connected to the upper end of the mounting groove 21. The encapsulation plate 22 is flush with the upper surface of the platform 2. A stabilizing device 3 is set inside the mounting groove 21. The stabilizing device 3 includes a support rod 4, an inner wall support clamp assembly 5, and an adjustment mechanism 6. There are two support rods 4, which are respectively set on the front and rear sides of the upper end of the placement groove 21, and the left and right ends are respectively fixedly connected to the left and right side surfaces of the placement groove 21. There are two inner wall support clamp assemblies 5, which are respectively set on the left and right sides of the placement groove 21. The adjustment mechanism 6 is set at the lower end of the two inner wall support clamp assemblies 5.

[0021] Specifically, the adjusting mechanism 6 can drive the inner wall support and clamping assembly 5 to support and clamp the inner wall of the elevator shaft outward, effectively eliminating the gap between the platform 2 and the shaft wall, greatly improving the stability of the platform 2 in the elevator shaft, and ensuring construction safety and accuracy.

[0022] Furthermore, the tripod body 1 achieves initial positioning of the components. After the adjustment mechanism 6 is triggered, it drives the inner wall support clamp component 5 to slide along the support rod 4, so that the support clamp structure moves closer to the well wall and fits, completing the stable fixation. All components work together to achieve a tight fit between the platform 2 and the well wall.

[0023] Example 2 In the second embodiment of this utility model, the inner wall support clamping assembly 5 includes a movable plate 51, a push rod 52, a clamping plate 53, and a pressure rod 54. The movable plate 51 is sleeved on the right end surface of the two support rods 4 and is slidably connected to the support rods 4. There are two push rods 52, which are respectively fixedly connected to the front and rear ends of the right surface of the movable plate 51. The right ends of the two push rods 52 extend out of the platform 2 and are slidably connected to the platform 2. The clamping plate 53 is fixedly connected to one end of the two push rods 52 that extends out of the platform 2. The pressure rod 54 is fixedly connected to the lower surface of the movable plate 51. Several anti-slip cones 7 are uniformly fixedly connected to the surfaces of the two clamping plates 53 that are far apart from each other; Several anti-slip blocks 8 are evenly fixedly connected to the upper surface of the encapsulation board 22.

[0024] Specifically, the elevator shaft inner wall is precisely supported and clamped by the coordinated operation of the movable plate 51, push rod 52 and clamping plate 53. The anti-slip cone block 7 can enhance the friction between the clamping plate 53 and the shaft wall, and the anti-slip block 8 can improve the safety of construction workers working on the platform 2. The multiple structures work together to ensure the stability and safety of the support components.

[0025] Furthermore, when the movable plate 51 slides along the support rod 4, it will drive the push rods 52 at both ends to move horizontally in sync, thereby pushing the clamping plate 53 closer to and into contact with the inner wall of the elevator shaft. The anti-slip cone 7 is embedded in the surface of the shaft wall to prevent slipping. At the same time, the anti-slip block 8 on the encapsulation plate 22 can play an anti-slip role for construction personnel or tools.

[0026] Example 3 In the third embodiment of this utility model, the adjusting mechanism 6 includes a linkage component 61 and a control self-locking component 62. The linkage component 61 is disposed at the lower end of the two pressure rods 54, and the control self-locking component 62 is disposed on the left side of the lower end of the linkage component 61. The linkage component 61 includes a rotating rod 611, a turntable 612, an arc-shaped extrusion groove 613, and a worm gear 614. The rotating rod 611 is located at the center inside the mounting groove 21, and its upper end is rotatably connected to the encapsulation plate 22, while its lower end is rotatably connected to the bottom surface inside the mounting groove 21. The turntable 612 is sleeved on the surface of the rotating rod 611 and is fixedly connected to the rotating rod 611. There are two arc-shaped extrusion grooves 613, which are respectively opened on the left and right sides of the turntable 612. The lower ends of the two pressure rods 54 are respectively located inside the two arc-shaped extrusion grooves 613 and are movably connected to the arc-shaped extrusion grooves 613. The worm gear 614 is sleeved on the lower surface of the rotating rod 611 and is fixedly connected to the rotating rod 611. A rotating groove 9 is provided on the front surface of platform 2; The self-locking control component 62 includes a worm gear 621, a knob 622, and an internal hexagonal slot 623. The worm gear 621 is located on the left side of the worm wheel 614 and is meshed with the worm wheel 614. Both the front and rear ends of the worm gear 621 are rotatably connected to the platform 2, and the front end extends into the rotating groove 9. The knob 622 is located inside the rotating groove 9 and is fixedly connected to the front end of the worm gear 621. The internal hexagonal slot 623 is formed on the front surface of the knob 622.

[0027] Specifically, by setting the coordination between the self-locking component 62 and the linkage component 61, the precise driving and stable locking of the inner wall support clamp component 5 can be achieved. This not only makes it easy for operators to quickly adjust the support clamp status, but also ensures the reliability of the support clamp fixation through the self-locking characteristics of the worm gear 621 and worm wheel 614, preventing accidental loosening.

[0028] Furthermore, the operator uses a tool to turn knob 622 to drive worm 621 to rotate. Worm 621 engages and drives worm wheel 614 and rotating rod 611 to rotate. Rotating rod 611 drives turntable 612 to rotate synchronously. The arc-shaped extrusion groove 613 of turntable 612 extrudes pressure rod 54 to trigger the action of inner wall support clamping assembly 5. After the support clamping is completed, the worm 621 and worm wheel 614 structure self-locks to prevent rotating rod 611 from rotating in the opposite direction.

[0029] Working principle: In use, the entire device is first hoisted to a preset height position inside the elevator shaft. The tripod 1, in conjunction with the elevator shaft and elevator entrance, provides support and positioning. When it is necessary to improve the stability of the platform 2 to eliminate gaps with the inner wall of the elevator shaft, the operator inserts an Allen wrench into the Allen groove 623 of the knob 622 and rotates it, causing the worm gear 621 to rotate synchronously within the rotating groove 9. Since the worm gear 621 is meshed with the worm wheel 614, the rotation of the worm gear 621 drives the worm wheel 614 and its fixed components. The rotating rod 611 rotates along the upper and lower end faces of the mounting groove 21, thereby causing the turntable 612 sleeved on the rotating rod 611 to rotate accordingly. During the rotation of the turntable 612, the arc-shaped extrusion grooves 613 on its left and right sides will exert a lateral extrusion force on the pressure rods 54 placed in the grooves, forcing the two pressure rods 54 to drive the movable plate 51 fixed to it to slide left and right along the support rod 4. When the movable plate 51 slides, it will push its push rod 52 to extend horizontally along the platform 2, ultimately causing the clamping plate at the end of the push rod 52 to extend horizontally. 53 moves towards the inner wall of the elevator shaft until the clamping plate 53 is tightly fitted against the inner wall. The anti-slip cone 7 enhances the friction between the clamping plate 53 and the shaft wall, achieving outward clamping and fixation of the inner wall. After clamping, the meshing structure of the worm gear 621 and worm wheel 614 has a self-locking characteristic, preventing the rotating rod 611 from rotating in the opposite direction and causing the clamping force to fail. This ensures that the clamping plate 53 always maintains a stable clamping state against the inner wall of the elevator shaft, effectively eliminating gaps between the platform 2 and the shaft wall, and preventing platform 2 from... When swaying or displacement occurs, and it is necessary to adjust the position of platform 2 or dismantle the device, rotating the knob 622 in the opposite direction will drive the worm gear 621 and worm wheel 614 to rotate in the opposite direction, thereby causing the rotating rod 611 to drive the turntable 612 to rotate in the opposite direction. The arc-shaped extrusion groove 613 extrudes and pulls the pressure rod 54 in the opposite direction, thereby driving the moving plate 51 to slide along the support rod 4 towards the inside of the placement groove 21, pushing the push rod 52 and the clamping plate 53 to simultaneously detach from the inner wall of the elevator shaft, so that construction personnel can adjust the position of platform 2 or lift and dismantle it as a whole.

[0030] In summary, by using the combined components of the tripod 1, platform 2, mounting slot 21, encapsulation plate 22, stabilizing device 3, support rod 4, inner wall clamping assembly 5, moving plate 51, push rod 52, clamping plate 53, pressure rod 54, adjusting mechanism 6, linkage assembly 61, rotating rod 611, turntable 612, arc-shaped extrusion groove 613, worm gear 614, self-locking control component 62, worm 621, knob 622, internal hexagonal groove 623, anti-slip cone block 7, and anti-slip block 8, the inner wall clamping assembly can be driven by the adjusting mechanism to clamp the inner wall of the elevator shaft outward, eliminating the shaking caused by the gap between the platform and the shaft wall, improving the stability of the platform, and ensuring construction safety and accuracy.
