Description

Technical Field

[0001] This utility model relates to the field of elevator shaft construction technology, and in particular to an anti-jamming elevator shaft operating platform. Background Technology

[0002] Traditional construction techniques typically involve erecting a frame using I-beams and support rods, reinforced with wooden formwork. Currently, simplified integrated operating platforms are widely used. However, during the lifting process, the direct friction between the frame and the shaft wall makes this method prone to jamming, tilting, and even partial jamming. This significantly increases the difficulty of the lifting operation, and the frequent adjustments and repairs severely delay the project schedule. Furthermore, if jamming occurs during hoisting, using tower cranes or other lifting equipment poses a significant safety hazard, further exacerbating construction risks.

[0003] Chinese patent CN221761301U discloses a detachable, liftable elevator shaft operating platform, which features rollers at the four corners for easy lifting. However, this design only provides a single-level construction platform, requiring hoisting after completion of the current level before proceeding to the next, resulting in limited overall construction efficiency. Furthermore, the operating platform lacks an effective support and fixing structure during construction, making it impossible to securely hold the platform in place. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-jamming elevator shaft operating platform to solve the problems existing in the background technology.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An anti-jamming elevator shaft operating platform is hoisted into the elevator shaft using a lifting device. The platform includes a multi-layered construction frame, each comprising multiple construction platforms. The height of each construction platform corresponds to the height of each floor of the elevator shaft. Multiple rows of sleeves are provided at the bottom of each construction platform, with each row of sleeves arranged coaxially. The axis of each sleeve is parallel to the direction of the elevator shaft door opening. A set of support rods is provided in the middle of each row of sleeves, with one end of each support rod extending out of the elevator shaft door opening and resting on the floor slab. A buckle is provided on the floor slab corresponding to the position of the support rod, and the buckle connects to a pre-embedded anchor rod on the floor slab.

[0007] Furthermore, the construction platform includes a base plate, and a longitudinally arranged connection is provided between the base plates of two adjacent sets of construction platforms.

[0008] Furthermore, the construction platform is equipped with a fence corresponding to the elevator door opening, the connecting rod is equipped with an L-shaped pin, and the fence is equipped with a retaining ring corresponding to the L-shaped pin, the retaining ring being fitted onto the L-shaped pin.

[0009] Furthermore, a baffle is provided above the base plate, and the baffle is inserted and fixed to the base plate.

[0010] Furthermore, the bottom of the lowest construction platform is equipped with casters at the four corners, and the casters abut against the inner wall of the elevator shaft.

[0011] The beneficial effects of this utility model are:

[0012] 1) The structure of support rods, buckles and sleeves can keep the construction frame stable and provide support.

[0013] 2) A three-layer construction platform is adopted. The first layer is responsible for support and material transfer, the second layer is used as a formwork removal platform, and the third layer is used for steel bar installation and concrete pouring. Compared with the traditional simple platform, it greatly improves construction efficiency and forms an assembly line operation mode.

[0014] 3) The casters serve as guides and facilitate movement, allowing the construction frame to move smoothly along the shaft wall, thus solving the problem of jamming caused by frictional resistance. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] See Figures 1-2 This utility model provides a technical solution:

[0020] like Figures 1-2As shown, an anti-jamming elevator shaft operating platform is hoisted into an elevator shaft 1 using a lifting device. The platform includes a multi-layered construction frame, comprising multiple construction platforms 2. The height of each construction platform 2 corresponds to the height of each floor of the elevator shaft 1. Multiple rows of sleeves 31 are provided at the bottom of each construction platform 2. Each row of sleeves 31 is coaxially arranged, with the axial direction of the sleeves 31 parallel to the direction of the elevator shaft doorway. A set of support rods 32 is provided in the middle of each row of sleeves 31. One end of each support rod 32 extends out of the elevator shaft doorway and is located on a floor slab 11. A buckle 12 is provided on the floor slab 11 corresponding to the position of the support rod 32, and the buckle 12 is connected to a pre-embedded anchor rod on the floor slab 11.

[0021] Using the above technical solution, the multi-story construction platform 2 is assembled and installed in advance according to the required construction scaffold height. Then, the entire construction scaffold is hoisted into the elevator shaft 1 using a tower crane or other lifting equipment, ensuring that the bottom of the construction platform 2 corresponds to each floor slab 11. At this point, the support rod 32 is inserted into each row of sleeves 31, and then the clip 12 is fitted onto the support rod 32. The clip 12 is then fixed to the pre-embedded anchor rod on the floor slab 11. This fixing method can be threaded connection, plug-in connection, or welding. By fixing the support rod 32 with the clip 12, the tower crane and the construction scaffold maintain a hoisting connection during construction. The support rod 32, clip 12, and sleeve 31 can keep the construction scaffold stable and prevent it from swaying. At the same time, the multiple sets of support rods 32, clip 12, and sleeves 31 can provide support for the construction scaffold, providing secondary fall protection.

[0022] like Figure 1 and Figure 2 As shown, the construction frame in this embodiment adopts a three-layer construction platform 2. The first layer is responsible for support and material transfer, the second layer serves as a formwork removal platform, and the third layer is used for steel bar installation and concrete pouring. Compared with the traditional simple platform, it greatly improves construction efficiency and forms an assembly line operation mode.

[0023] When the construction frame needs to be lifted, simply pull out the support rod 32 and use a tower crane or other lifting device to hoist the entire construction frame. After hoisting into place, continue to use the support rod 32, buckle 12, and sleeve 31 for support and fixation. The support structure of the entire construction frame is simple and easy to disassemble.

[0024] Furthermore, the bottom of the lowest construction platform 2 is provided with casters 28 at the four corners, and the casters 28 abut against the inner wall of the elevator shaft 1.

[0025] Compared to traditional hard-contact lifting methods, the swivel casters 28, with their low-friction rolling characteristics, allow the construction frame to move smoothly along the shaft wall, solving the jamming problem caused by frictional resistance. Operators can easily lift the construction frame vertically using only the lifting device; at the same time, the guiding function of the swivel casters 28 can effectively prevent platform deviation, ensuring a safe and controllable lifting process.

[0026] Furthermore, the construction platform 2 includes a base plate 21, and the base plates 21 of two adjacent sets of construction platforms 2 are connected in a longitudinal manner. The top of the uppermost construction platform 2 is provided with a top plate 23, which is connected to the lifting mechanism.

[0027] Furthermore, the construction platform 2 is provided with a fence 25 at the position corresponding to the elevator door opening, the connecting rod 22 is provided with an L-shaped pin 24, and the fence 25 is provided with a retaining ring 26 at the position corresponding to the L-shaped pin 24. The retaining ring 26 is sleeved on the L-shaped pin 24.

[0028] With the above technical solution, the retaining ring 26 on the fence 25 is inserted into the L-shaped pin 24, so that the fence 25 can be rotated, thereby opening or closing the fence 25. When the fence 25 is not needed, it can be lifted up and removed from the L-shaped pin 24.

[0029] Furthermore, a baffle 27 is provided above the base plate 21, and the baffle 27 is inserted and fixed to the base plate 21.

[0030] Through the above technical solution, the baffle 27 is used to prevent the tools on the base plate 21 from falling. The baffle 27 is provided with a plug at the bottom that can be inserted into the socket of the base plate 21, thereby realizing the connection between the baffle 27 and the base plate 21. At the same time, the baffle 27 can be quickly removed when it is not needed.

[0031] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
