[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0025] like Figures 1-4 The diagram shows the frame structure of a steel belt traction machine for an elevator according to this embodiment. The elevator includes components such as counterweight guide rails, a steel belt traction machine, a car, and car guide rails. All of these components are conventional components in the prior art, and their installation methods and functions are also existing technologies. The steel belt traction machine frame structure of this embodiment includes a support unit and a base. The support unit is arranged corresponding to the counterweight guide rails on opposite sides and includes a fixed seat, a pressure guide plate, a bolt assembly, an adjusting plate, a top rod bolt, and a tension bolt. The fixed seat is fixed to the counterweight guide rail by the pressure guide plate and the bolt assembly. The assembly method of the pressure guide plate and the counterweight guide rail is common knowledge in the prior art.

[0026] The fixed base has a top plate located above the top of the counterweight guide rail. The aforementioned adjusting plate is arranged below the top plate, with its bottom surface abutting against the top of the counterweight guide rail. A top rod bolt extends vertically. This top rod bolt is threadedly connected to the adjusting plate and has an abutting end that abuts against the top plate. In this embodiment, the top rod bolts are arranged on opposite sides of the counterweight guide rail. By turning the top rod bolts in both directions, the fixed base can be driven to rise and fall relative to the adjusting plate, thereby adjusting the lifting height of the fixed base. The aforementioned base is connected between the fixed bases of the two side support units. The base and the top plate are fixedly connected by a bolt assembly. When the lifting height of the fixed base is adjusted by the top rod bolt, the base adjusts accordingly.

[0027] The aforementioned steel belt traction machine is fixed to the base. The steel belt traction machine and the base are connected by bolt assemblies. During installation, a shock-absorbing pad is installed between the steel belt traction machine and the base to isolate the vibration generated during the operation of the steel belt traction machine.

[0028] According to the actual structural design, through holes are machined on the top plate of the fixed seat and the machine base, and corresponding threaded holes are machined on the adjusting plate. The pull bolt moves up and down through the through holes and is threadedly connected to the threaded holes. There is a gap between the head of the pull bolt and the top plate and the machine base, so that the adjusting plate is not locked to the top plate and the machine base. Through the above structural design, the pull bolt pulls the adjusting plate, but does not restrict the up and down movement of the fixed seat and the machine base relative to the adjusting plate, thereby improving the stability of the push rod bolt during adjustment.

[0029] In this embodiment, the aforementioned fixing base has a surrounding plate. A top plate is welded to the top of the surrounding plate. The surrounding plate is arranged beside the counterweight guide rail and includes a side plate and two bent edges formed on opposite sides of the side plate. The two bent edges are arranged on opposite sides of the counterweight guide rail in the width direction or thickness direction. A receiving space is formed between the two bent edges. The aforementioned adjusting plate is arranged in the receiving space and is confined between the two bent edges to restrict the horizontal movement of the adjusting plate.

[0030] In this embodiment, a notch is machined at the edge of the aforementioned base. This notch faces the car. The car guide rails are inserted vertically into the notch and are fixedly connected to the base via guide plates and bolt assemblies. Through the above structural design, the base does not obstruct the car guide rails, allowing the car guide rails to continue extending upwards. This enables the entire car to pass over the base during operation, and the overall frame structure does not occupy the upward space of the car, thus maximizing the utilization of the top floor space of the hoistway.

[0031] During adjustment, slightly loosen the pressure guide plate and bolt assembly between the fixed seat and the counterweight guide rail, tighten each top rod bolt, and adjust the lifting height of the fixed seats on both sides according to the actual situation to adjust the level of the machine base. Then, lock the fixed seats onto the counterweight guide rail using the pressure guide plate. Through this method, when the overall structure is assembled onto the counterweight guide rail, the horizontal position of the overall structure can be adjusted conveniently, saving time and effort, effectively meeting the assembly requirements of the steel belt traction machine, and demonstrating strong practicality.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
