Description

Technical Field

[0001] This utility model relates to the technical field of parallel elevator installation structure, specifically a parallel elevator installation structure. Background Technology

[0002] The parallel elevator installation structure disclosed in the authorization announcement number CN219408775U includes two parallel elevator shafts, and a common guide rail support is provided in the depth direction between the two elevator shafts; the common guide rail support is provided with two counterweight devices distributed front and rear, and cars located in each elevator shaft are provided on the left and right sides of the common guide rail support.

[0003] In fact, the new type of application has the characteristics of effectively reducing installation space and shortening installation time.

[0004] The technical solution in the prior art reduces installation space by using a shared guide rail. However, since it only uses a single shared rail to limit the movement of two elevator cars, it lacks a reinforcing structure. The shared rail can bend under large external forces, affecting the safe operation of the elevator. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a parallel elevator installation structure that solves the problem that relying solely on a single shared track to simultaneously move and limit the movement of two elevator cars lacks a reinforcing structure, and the shared track can bend due to significant external forces, thus affecting the safe operation of the elevator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a parallel elevator installation structure, including a common track, connecting blocks slidably connected to both sides of the common track, a car body fixedly connected to the side of the connecting blocks, a machine support beam fixedly connected to the top of the common track, a support frame fixedly connected to both sides of the machine support beam in an axisymmetric manner, a limit frame fixedly connected to the top surface of the support frame, a counterweight cable for providing lifting power to the counterweight is provided inside the limit frame, and an installation beam for bearing the installation load is fixedly connected to the surface of the common track in an axisymmetric manner, with an installation hole for bolt connection at one end of the installation beam.

[0007] In one specific embodiment, the limiting frame is fixed symmetrically to both sides of the machine beam by a support frame.

[0008] In one specific embodiment, at least two mounting beams are provided at intervals along the length of the common track.

[0009] In one specific embodiment, the limiting frame is configured as a structure that can constrain and guide the movement trajectory of the counterweight steel cable.

[0010] In one specific embodiment, the mounting hole of the mounting beam is opened at the free end of the mounting beam away from the common track.

[0011] In one specific embodiment, the counterweight cable is configured as a cable for hoisting the elevator counterweight.

[0012] Compared with the prior art, this utility model provides a parallel elevator installation structure, which has the following advantages:

[0013] In the technical solution disclosed in this utility model, multi-point distributed load-bearing fixation is achieved by using symmetrically arranged mounting beams and mounting holes on both sides of the shared track, which effectively prevents the track from bending and deforming due to its length, and ensures the smooth and safe sliding of the carriage along the track; at the same time, the limiting frame fixed by the support frame on both sides of the support beam precisely constrains the movement trajectory of the counterweight steel cable, which not only optimizes the operating efficiency of the lifting mechanism, but also avoids the interference of the mounting beam on the dynamic operation of the steel cable.

[0014] The installation beams and limiting frames designed in this invention significantly enhance the overall rigidity of the shared track by fixing multiple installation beams with installation holes at axially symmetrical intervals along the length of the shared track. This effectively resists the risk of bending deformation caused by the movement of the car body or external loads, ensuring the stability and operational safety of the connecting block and the car body sliding along the track. At the same time, the support frames fixed to both sides of the machine beam and the limiting frames on the top surface of the support frames form a precise guiding structure for the counterweight steel cable. This structure ensures that the counterweight steel cable, which provides lifting power to the counterweight, can move smoothly along the set trajectory. Furthermore, the spatial arrangement ensures that its movement path avoids the installation beams used to bear the installation load, fundamentally solving the problem of potential obstruction or interference to the counterweight steel cable in traditional structures. This improves the overall reliability and space utilization efficiency of the parallel elevator system. Attached Figure Description

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, a parallel elevator installation structure includes a common track 1, with connecting blocks 2 slidably connected to both sides of the common track 1, a car body 3 fixedly connected to the side of the connecting blocks 2, a machine support beam 4 fixedly connected to the top of the common track 1, a support frame 5 fixedly connected to both sides of the machine support beam 4 in an axisymmetric manner, a limit frame 6 fixedly connected to the top surface of the support frame 5, a counterweight steel cable 7 provided inside the limit frame 6 for providing lifting power to the counterweight, and an installation beam 8 for bearing the installation load fixedly connected to the surface of the common track 1 in an axisymmetric manner, with an installation hole for bolt connection at one end of the installation beam 8.

[0023] The specific problem addressed in this embodiment is the lack of reinforcement structure in using only a single shared track to simultaneously limit the movement of two elevator cars, which can lead to bending of the shared track due to large external forces, affecting the safe operation of the elevator. This invention utilizes symmetrically arranged mounting beams 8 and their mounting holes on both sides of the shared track 1 to achieve multi-point distributed load-bearing fixation, effectively preventing bending deformation of the track due to its length and ensuring the smooth and safe sliding of the car body 3 along the track. Simultaneously, the limiting frame 6 fixed to the support frames 5 on both sides of the machine support beam 4 precisely constrains the movement trajectory of the counterweight steel cable 7, optimizing the operating efficiency of the lifting mechanism and avoiding interference from the mounting beams 8 on the dynamic movement of the steel cable.

[0024] At least two mounting beams 8 are spaced apart along the length of the common track 1; the limiting frame 6 is fixed axially symmetrically to both sides of the machine beam 4 by the support frame 5. In this specific embodiment, by fixing multiple mounting beams 8 with mounting holes axially symmetrically at intervals along the length of the common track 1, the overall rigidity of the common track 1 is significantly enhanced, effectively resisting the risk of bending deformation caused by the movement of the car body 3 or the action of external loads, and ensuring the stability and operational safety of the connecting block 2 and the car body 3 sliding along the track; at the same time, the support frame 5 fixed to both sides of the machine beam 4 and the limiting frame 6 on the top surface of the support frame 5 form a precise guiding structure for the counterweight steel cable 7. This structure not only ensures that the counterweight steel cable 7, which provides lifting power to the counterweight, can move smoothly along the set trajectory, but also avoids the installation beam 8 used to bear the installation load through spatial arrangement, fundamentally solving the problem that the counterweight steel cable may be obstructed or interfered with in the traditional structure, and improving the overall reliability and space utilization efficiency of the parallel elevator system.

[0025] In this specific embodiment, the limiting frame 6 is configured as a structure that can constrain and guide the movement trajectory of the counterweight cable 7. The limiting frame 6 is designed as a structure with a vertical guide channel, and its internal contour matches the outer diameter of the counterweight cable 7, so that the counterweight cable 7, which runs through the limiting frame 6, is always restricted to moving within a preset linear trajectory during operation. This structure, combined with the symmetrical fixed layout of the support frame 5, ensures that the cable is subjected to balanced force and eliminates the risk of the counterweight cable 7 swinging or deviating and colliding with the surrounding mounting beams 8. Its core beneficial effect is that: by rigidly constraining the movement path of the counterweight cable 7 through the limiting frame 6, the accuracy and reliability of the power transmission of the counterweight system are significantly improved. At the same time, because the movement trajectory of the counterweight cable 7 is strictly limited within the channel of the limiting frame 6, the movement interference between the fixed structure such as the mounting beams 8 and the dynamic counterweight cable 7 is completely eliminated, ensuring the long-term stable operation of the parallel elevator system.

[0026] In this specific embodiment, the mounting hole of the mounting beam 8 is opened at the free end of the mounting beam 8 away from the common track 1. The free end of the mounting beam 8 extending to the outside of the common track 1 is machined to form a circular mounting hole penetrating the end face of the free end. A high-strength bolt is inserted through this hole to achieve a secure connection with the elevator shaft wall. Its core beneficial effect is that, because the mounting hole is opened at the free end of the mounting beam 8 away from the common track 1, the mounting beam 8 forms a maximum lever arm support structure when fixed to the shaft wall, significantly improving the common track 1's resistance to bending deformation. At the same time, the opening design at the free end facilitates bolt locking by construction personnel through external operation, and ensures that the installation load is directly transferred to the bearing point of the shaft wall through the mounting beam 8, avoiding local deformation of the track body 1 due to concentrated force, thereby effectively maintaining the straightness accuracy of the sliding path of the car body 3.

[0027] Working principle: The mounting beam 8 is bolted to the elevator shaft wall through its mounting holes to form a multi-level support point, so that the common track 1 can obtain uniform distributed load; the connecting blocks 2 on both sides slide along the surface of the common track 1 and drive the fixed car body 3 to achieve vertical lifting; at the same time, the support frame 5 fixed to the top of the track support beam 4 and the limiting frame 6 form the installation foundation of the counterweight system. The counterweight steel cable 7 placed inside the limiting frame 6 moves vertically under the drive of the traction machine to balance the load of the car body 3; the interval layout of the mounting beam 8 prevents bending by dispersing the stress of the common track 1, while the limiting frame 6 restricts the running trajectory of the counterweight steel cable 7 to isolate it from the mounting beam 8 in space, avoiding collision and interference between the dynamic steel cable and the fixed support structure.
