Abstract
Description
Technical Field
[0001] The utility model relates to an integrated fixing device for elevator traction ropes, in particular to a rope head seat at the top of a guide rail of a machine-roomless elevator. Background Art
[0002] The traction ropes of an elevator are traction devices connecting the traction machine with devices such as the car and the counterweight. During the relative up and down movement of the car and the counterweight, the relative length of the traction ropes also changes. Therefore, the rope heads of the traction ropes need to be fixed. Conventionally, the rope heads of the traction ropes can be fixed in the machine room of the hoistway. However, in a machine-roomless elevator, there is no corresponding position, and the rope heads need to be installed above the height where the car can run. Therefore, the rope head installation structure needs to make full use of the top space of the hoistway, so the rope head fixing device needs to be improved. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies existing in the prior art, and to provide a rope head seat at the top of a guide rail of a machine-roomless elevator.
[0004] The technical solution adopted by the utility model to solve the above problems is: the rope head seat includes a combined bracket and a fixing bracket. The combined bracket is connected to the ring beam through the fixing bracket. The combined bracket includes a guide rail fixing bracket, a rope head fixing bracket and a speed limiter bracket. The fixing bracket extends horizontally based on the ring beam and fixes the guide rail fixing bracket above the vertical extension of the guide rail. The rope head fixing bracket and the speed limiter bracket are arranged on both sides of the guide rail fixing bracket. The end fixing part of the traction rope is fixed on the rope head fixing bracket, and the speed limiter is fixed on the speed limiter bracket and cooperates with the guide rail to work. The guide rail fixing bracket, the rope head fixing bracket and the speed limiter bracket are welded and fixed together. The rope head fixing structure, the speed limiter fixing structure and the guide rail fixing structure are concentrated together, effectively saving space, and through the limitation of the structure, avoiding interference between the working structures, meeting the requirements for the space of the machine-roomless elevator hoistway, and adapting to various elevator layout methods.
[0005] Further, the combined bracket is formed by welding a rear support plate, a guide rail fixing plate, a rope head plate and a speed limiter plate. The rear support plate is set corresponding to the overall width of the combined bracket, and the ends on both sides are bent to form side enclosing edges. The side of the guide rail fixing plate is formed into a "U" - shaped structure and is fixedly welded to the middle part with the opening facing the rear support plate. The flat back surface of the guide rail fixing plate is the guide rail fixing surface. The rope head plate and the speed limiter plate are respectively welded and fixed at the top of the space between the guide rail fixing plate and the side enclosing walls on both sides. The combined bracket is mainly formed by welding four combined parts, which is convenient for production and processing, has high structural strength, can be produced quickly, has a good integrated effect of the structure, and saves space.
[0006] Furthermore, the guide rail fixing frame is formed by combining a guide rail fixing plate and the middle portion of a rear support plate. The guide rail fixing frame is connected to the guide rail via a guide rail fixing member. The bottom plane of the guide rail is aligned with the surface of the guide rail fixing plate, and the guide rail fixing plate is provided with multiple sets of fixing holes. The guide rail fixing frame is directly fixed vertically to the guide rail, forming a stable fixed foundation, fixing the guide rail to the hoistway foundation, and preventing vibration during elevator operation.
[0007] Furthermore, the rope end fixing frame is composed of a rope end plate, a rear support plate on that side, and a side wall. A rope end space is enclosed below the rope end plate, and the end of the traction rope is fixed to the rope end plate from bottom to top via a rope end rod. A protective space is provided below the rope end fixing plate to protect the rope end structure. The rope end plate has a shock-absorbing spring to reduce vibration generated by the traction rope during operation.
[0008] Furthermore, the speed governor bracket consists of a speed governor plate, a rear support plate, and a side wall. The speed governor plate is provided with mounting holes and side limit strips are also provided on the sides of the speed governor plate. The speed governor needs to detect the linear speed of the passing traction rope and limit the speed when it exceeds the speed limit. Therefore, its fixed position requires high requirements and requires installation and positioning through several positioning structures to ensure installation accuracy.
[0009] Compared with the existing technology, the utility model has the following advantages and effects: the design is an improvement of the rope head seat structure at the top of the guide rail of an elevator without a machine room, and the main traction rope is centrally fixed through the working equipment there, thereby improving the utilization rate of space, being suitable for the form of elevator without a machine room, and being convenient to process and produce, thereby improving production efficiency.
