Description

Technical Field

[0001] This utility model relates to the technical field of elevator steel structure installation equipment, and in particular to an elevator steel structure shaft mounting bracket. Background Technology

[0002] The elevator shaft, typically constructed of steel, is the vertical passageway housing the elevator equipment and is a crucial component of the elevator system. An elevator shaft mounting frame is a device used to assist in the installation of the elevator shaft. During installation, the mounting frame provides precise positioning for each component, ensuring they are installed in the correct positions, guaranteeing the shaft's verticality and horizontality, and providing stable support to the shaft structure and the subsequent elevator equipment. Simultaneously, it provides a stable working platform for construction workers, facilitating welding and bolting operations, improving construction efficiency, and ensuring construction safety.

[0003] Traditional elevator shafts are installed from bottom to top. After each floor is completed, a mounting bracket is bolted to secure the auxiliary components. When installing the upper floor, to avoid affecting the completed parts, the connection between the lower floor and the mounting bracket must be disassembled, and the bracket re-secured after it rises. However, this type of mounting bracket relies on bolts for fixation, and the bolts must be disassembled and reassembled each time the steel structure rises. This is not only cumbersome but also consumes a lot of time and manpower, affecting construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the problems of traditional elevator steel structure shafts being installed from bottom to top, with the mounting brackets fixed by bolts, requiring disassembly and reassembly for each floor ascent, which is cumbersome, time-consuming, labor-intensive, and affects construction efficiency. This utility model proposes a matching mounting bracket for elevator steel structure shafts.

[0005] The technical solution of this utility model is as follows: an elevator steel structure shaft mounting bracket, including an elevator pit and multiple pairs of vertical steel structures installed on the elevator pit. Each pair of vertical steel structures has a horizontal steel structure in the middle. It also includes: a base and a top seat corresponding to the top of the elevator pit; a slot formed in the horizontal steel structure, with sleeves fixedly connected to the outer walls of both sides of the base and the top seat; a telescopic mechanism installed in the sleeves to fix the base and the top seat to the horizontal steel structure at the corresponding height; and an anti-reverse mechanism slidably inserted at both ends of the sleeves to lock the telescopic mechanism after it is opened.

[0006] Optionally, the telescopic mechanism includes mounting slots at both ends of the sleeve, each mounting slot having a cylinder fixedly connected inside. Each mounting slot at both ends of the sleeve has a telescopic block slidably connected to it, and each telescopic block has a guide block fixedly connected to the end of the telescopic block away from the sleeve, which is inserted into the slot.

[0007] Optionally, a pair of limiting blocks are fixedly connected to the outer wall of the guide block away from the telescopic block, and a pair of positioning slots for the limiting blocks to be engaged are opened at both ends of the sleeve.

[0008] Optionally, the anti-reverse mechanism includes a telescopic lever that is slidably connected to both ends of the sleeve to hold the telescopic block. A pull head is fixedly connected to the end of the telescopic lever away from the sleeve. A return spring is also sleeved on the telescopic lever. One end of the return spring is fixedly connected to the outer wall of the sleeve, and the other end of the return spring is fixedly connected to the pull head.

[0009] Optionally, a scissor-type lifting mechanism is provided in the middle of the base and the top seat.

[0010] Optionally, a top plate is fixedly connected to the upper surface of the top seat.

[0011] Optionally, a pair of U-shaped guide rails are fixedly connected to the top of the elevator pit, and a limiting roller that is inserted into the U-shaped guide rails and rolls is fixedly connected to the lower surface of the base.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model utilizes the cooperation of a base, top seat, slot, sleeve, telescopic mechanism, and anti-reverse mechanism to enable the matching mounting bracket to be quickly fixed to the guide block by a cylinder, greatly simplifying the operation process and reducing the difficulty of manual operation. At the same time, it reduces repetitive disassembly and assembly work at heights, significantly reducing physical exertion and effectively alleviating labor intensity. Furthermore, the anti-reverse mechanism avoids the safety risks associated with frequent disassembly and assembly at heights, further enhancing the safety of the installation process and providing more reliable protection for construction personnel.

[0026] Example

[0027] like Figures 1 to 5 As shown, this utility model proposes an elevator steel structure shaft mounting bracket, including an elevator pit 1 and multiple pairs of vertical steel structures 101 installed on the elevator pit 1. Each pair of vertical steel structures 101 has a horizontal steel structure 102 in the middle. The top of the elevator pit 1 has a corresponding base 11 and a top seat 12. The middle of the base 11 and the top seat 12 is provided with a scissor-type lifting mechanism 14. A top plate 13 is fixedly connected to the upper surface of the top seat 12. The top plate 13 is a platform for installation workers to step on, and the top plate 13 is also provided with anti-slip rubber pads. A slot 103 is opened in the horizontal steel structure 102. The size of the slot 103 is just enough for the guide block 25 to be inserted into the slot 103 to ensure a tight connection. The outer walls on both sides of the base 11 and the top seat 12 are fixedly connected with sleeves 2.

[0028] Among them, such as Figure 4 , Figure 5 As shown, a telescopic mechanism is installed inside the sleeve 2 to fix the base 11 and the top seat 12 on the horizontal steel structure 102 at the corresponding height. The telescopic mechanism includes mounting slots 22 at both ends of the sleeve 2. A cylinder 23 is fixedly connected inside each mounting slot 22. Telescopic blocks 24 are slidably connected to the mounting slots 22 at both ends of the sleeve 2. A guide block 25 is fixedly connected to the end of the telescopic block 24 away from the sleeve 2, which is inserted into the slot 103. One end of the guide block 25 is set to be inclined, which is to ensure that one end of the guide block 25 is inserted into the slot 103 smoothly and conveniently.

[0029] In addition, such as Figures 3 to 5 As shown, a pair of limiting blocks 26 are fixedly connected to the outer wall of the guide block 25 away from the telescopic block 24. Both ends of the sleeve 2 are provided with a pair of positioning slots 27 for the limiting blocks 26 to be inserted. The positioning slots 27 are limited by the limiting blocks 26 to ensure that the telescopic block 24 retracts into the mounting slot 22.

[0030] It is worth noting that, such as Figure 4As shown, the collet 2 has anti-reverse mechanisms slidably inserted at both ends. These mechanisms lock the telescopic mechanism after it has been opened. The anti-reverse mechanism includes telescopic levers 3 slidably connected to both ends of the collet 2, which hold the telescopic blocks 24 in place. A pull head 31 is fixedly connected to the end of the telescopic lever 3 furthest from the collet 2. The pull head 31 allows the telescopic lever 3 to slide easily and effortlessly by being manually pulled. A return spring 32 is also fitted onto the telescopic lever 3. The return spring 32 ensures that the telescopic lever 3 remains locked within the mounting groove 22, holding the telescopic blocks 24 in place. One end of the return spring 32 is fixedly connected to the outer wall of the collet 2, and the other end is fixedly connected to the pull head 31.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, a pair of U-shaped guide rails 4 are fixedly connected to the top of the elevator pit 1. A limiting roller 21, which rolls within the U-shaped guide rails 4, is fixedly connected to the lower surface of the base 11. The limiting roller 21 slides within the U-shaped guide rails 4, thereby limiting the position of the base 11 at the top of the elevator pit 1 and also supporting the base 11 in its operation at the top of the elevator pit 1. The U-shaped guide rails 4 are bolted to the top of the elevator pit 1.

[0032] In this embodiment, when the elevator steel structure shaft mounting bracket is required, multiple vertical steel structures 101 and horizontal steel structures 102 are first assembled into the bracket. Figure 1 The state shown is as follows. Next, move the base 11, top seat 12, top plate 13, and scissor lift mechanism 14 to the top of the elevator pit 1, ensuring that the limiting rollers 21 at the bottom of the base 11 engage with the corresponding U-shaped guide rails 4, until the base 11 moves to the middle position at the top of the elevator pit 1. At this point, simply activate the scissor lift mechanism 14 in the middle of the base 11 and top seat 12 to push the top seat 12 and top plate 13 up and down to the desired position. Figure 1 The state shown is as follows. Immediately afterward, when the top seat 12 is raised and lowered to the same horizontal level as the sleeves 2 on both sides and the corresponding horizontal steel structure 102, all the cylinders 23 on the top seat 12 can be activated. The piston rods of the cylinders 23 push the corresponding telescopic blocks 24 to move along the mounting groove 22 to the slot 103, so that the telescopic blocks 24 drive the guide blocks 25 to insert into the corresponding horizontal steel structure 102, thereby fixing the top seat 12 on the pair of horizontal steel structures 102 on the top floor.

[0033] When it is necessary to install the vertical steel structure 101, simply activate the scissor lift mechanism 14, causing it to fold and shorten, as the top seat 12 is fixed in place. This causes the scissor lift mechanism 14 to move the bottom base 11 upwards until it reaches the corresponding height of the horizontal steel structure 102. At this point, the retaining sleeves 2 on both sides of the base 11 can be activated, and the above operation can be repeated. This process, which will not be elaborated here, allows the fixed base 11 to become a support platform for the next rise of the top seat 12. This cycle is repeated continuously to gradually complete the installation of the elevator steel structure shaft from bottom to top.

[0034] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
