Description

Technical Field

[0001] This utility model relates to the field of traction machine technology, specifically an adjustable traction machine for elevators. Background Technology

[0002] The elevator traction machine is the core power unit of the elevator system. Its core function is to drive the traction sheave to rotate and use the static friction between the traction rope and the traction sheave groove to drive the car and counterweight to move vertically up and down along the guide rail. The stability of the traction machine directly determines the elevator's operating efficiency, safety and smoothness.

[0003] With the continuous development of the construction industry, not only are elevators commonly installed in high-rise buildings, but more and more low-rise buildings and old residential communities are also adding elevators. Chinese Patent Announcement No. CN 212076108 U discloses an adjustable elevator traction machine mounting bracket for installing a traction machine, including a frame vertical beam, a frame horizontal beam, and a traction machine mounting beam. The frame vertical beam is provided with multiple frame horizontal beam placement slots, which are distributed sequentially from bottom to top on the frame vertical beam. The frame horizontal beam is placed in the frame horizontal beam placement slot, the traction machine mounting beam is installed on the frame horizontal beam, and the traction machine is installed on the traction machine mounting beam.

[0004] The aforementioned traction machine mounting bracket increases the contact area between the wire rope and the traction sheave by adjusting the height of the traction machine. However, the aforementioned traction machine mounting bracket can only change the height of the traction machine. When installing elevators in small buildings, especially old residential buildings, the space in the elevator shaft is very limited, and there are many buildings where the location of the traction machine work area and the elevator shaft does not match. When installing traction machines in such buildings, simply adjusting the height of the traction machine cannot meet the installation requirements of the traction machine. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable traction machine for elevators, which can change the height of the traction machine by using the screw structure and threaded cylinder of the adjustment component, and can change the lateral position of the traction machine when the transverse frame moves along the rail frame, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable traction machine for elevators includes

[0008] The truss, which supports the traction machine, consists of three trusses, and the two ends of the three trusses are fixedly connected to two side frames respectively; the bottom ends of the two side frames are fixedly connected to adjustment components.

[0009] The rail frame, which supports the adjustment component, has two rail frames, and the tops of the two rail frames are fixedly connected to the two ends of the two connecting frames respectively.

[0010] The adjustment assembly includes a threaded cylinder, the top of which is fixedly connected to the bottom of the side frame; the inner side of the threaded cylinder is threadedly connected to the screw structure; the bottom of the screw structure is fixedly connected to the middle of the top of the transverse frame; side sliders are fixedly connected to the inner sides of both ends of the transverse frame; an upper slider is fixedly connected to the middle of the bottom of the transverse frame; and multiple positioning bolts are fitted on both sides of the transverse frame.

[0011] The rail frame includes a main frame, with an upper slide rail fixedly connected to the top center of the main frame, and side slide rails fixedly connected to both sides of the main frame; two side sliders are slidably connected to the two side slide rails respectively, and an upper slider is slidably connected to the upper slide rail; both sides of the top of the main frame are integrally provided with extension plates, and both extension plates are provided with through grooves, with multiple positioning bolts located in the two through grooves respectively;

[0012] The screw structure includes a screw, one end of which is coaxially threaded to a threaded cylinder, and a rotating component is coaxially fixedly connected to the end of the screw away from the threaded cylinder. The rotating component is rotatably connected to a fixed component, and the bottom of the fixed component is fixedly connected to the middle of the top of the transverse frame.

[0013] As a further technical solution of this utility model, the rotating component is annular, and the screw is located inside the rotating component. The rotating component is located inside the fixed component and is coaxially arranged with the fixed component.

[0014] As a further technical solution of this utility model, the screw, rotating part and fixing part are all provided with cross-shaped insertion holes, and the diameter of multiple insertion holes is the same; a fixing bolt is provided in the insertion hole of the fixing part, the fixing bolt passes through the screw, rotating part and fixing part and the end of the fixing bolt is threadedly connected to the nut.

[0015] As a further technical solution of this utility model, the main frame is located in the middle of the inner side of the transverse frame, and the two sides of the transverse frame are fixedly connected to the two extension plates by multiple positioning bolts; the length of the two extension plates is the same as the length of the main frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, during the installation of a traction machine, rotating the screw can drive the threaded cylinder to rise and fall, thereby changing the height of the two side frames and three trusses, and thus changing the height of the traction machine. After determining the height of the threaded cylinder, the fixing bolts are inserted into the holes of the screw, rotating parts and fixing parts and the fixing bolts are fixed with nuts, so that the fixing bolts can fix the rotating screw, prevent the rotating screw from rotating arbitrarily, ensure the stability of the threaded cylinder, and prevent the height of the traction machine from changing and the traction machine from tilting.

[0018] 2. This utility model allows four transverse frames to move laterally along the two main frames after loosening multiple positioning bolts, thus changing the lateral position of the traction machine. Combined with the threaded cylinder and screw structure, this enables the traction machine to move in multiple directions, reducing the difficulty of installation. The upper slide rail and two side slide rails ensure smoother movement of the transverse frames and prevent swaying or tilting. Tightening the positioning bolts secures the transverse frames to the main frames, preventing them from moving arbitrarily. Furthermore, the two connecting frames further enhance the stability of the transverse frames by blocking their movement. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-15 In this embodiment of the present invention, an adjustable traction machine for elevators includes...

[0039] Truss 2, three trusses 2 are provided to support the traction machine 8, and the two ends of the three trusses 2 are respectively fixedly connected to two side frames 3; the bottom of the two ends of the two side frames 3 are fixedly connected to adjustment components 4.

[0040] Two rail frames 5 are provided to support the adjustment assembly 4, and the tops of the two rail frames 5 are respectively fixedly connected to the two ends of the two connecting frames 6.

[0041] The adjustment assembly 4 includes a threaded cylinder 41, the top of which is fixedly connected to the bottom of the side frame 3; the inner side of the threaded cylinder 41 is threadedly connected to the screw structure 42; the bottom of the screw structure 42 is fixedly connected to the middle of the top of the transverse frame 43; side sliders 44 are fixedly connected to the inner sides of both ends of the transverse frame 43; an upper slider 46 is fixedly connected to the middle of the bottom of the transverse frame 43; and multiple positioning bolts 45 are fitted on both sides of the transverse frame 43.

[0042] The screw structure 42 includes a screw 421, one end of which is coaxially threaded to the threaded cylinder 41, and a rotating member 422 is coaxially fixedly connected to the end of the screw 421 away from the threaded cylinder 41. The rotating member 422 is rotatably connected to the fixed member 423, and the bottom of the fixed member 423 is fixedly connected to the middle of the top of the transverse frame 43.

[0043] The rotating component 422 is annular, and the screw 421 is located inside the rotating component 422. The rotating component 422 is located inside the fixed component 423 and is coaxially arranged with the fixed component 423.

[0044] The screw 421, rotating member 422 and fixing member 423 are all provided with cross-shaped insertion holes 424, and the diameter of multiple insertion holes 424 is the same; a fixing bolt 425 is provided in the insertion hole 424 of the fixing member 423, the fixing bolt 425 passes through the screw 421, rotating member 422 and fixing member 423 and the end of the fixing bolt 425 is threadedly connected to the nut 426.

[0045] By adopting the above technical solution, when installing the traction machine 8, rotating the screw 421 can drive the threaded cylinder 41 to rise and fall, thereby changing the height of the two side frames 3 and the three trusses 2, and thus changing the height of the traction machine 8. After determining the height of the threaded cylinder 41, the fixing bolt 425 is inserted into the insertion holes 424 of the screw 421, the rotating part 422 and the fixing part 423 and the fixing bolt 425 is fixed with the nut 426, so that the fixing bolt 425 can fix the rotating screw 421, prevent the rotating screw 421 from rotating arbitrarily, and ensure the stability of the threaded cylinder 41. This can prevent the height of the traction machine 8 from changing and also prevent the traction machine 8 from tilting.

[0046] In this embodiment, the rail frame 5 includes a main frame 51, with an upper slide rail 52 fixedly connected to the top center of the main frame 51, and side slide rails 53 fixedly connected to both sides of the main frame 51; two side sliders 44 are slidably connected to the two side slide rails 53 respectively, and an upper slider 46 is slidably connected to the upper slide rail 52; an extension plate 56 is integrally provided on both sides of the top of the main frame 51, and a through groove 54 is provided on both extension plates 56, with multiple positioning bolts 45 located in the two through grooves 54 respectively;

[0047] The main frame 51 is located in the middle of the inner side of the transverse frame 43, and the two sides of the transverse frame 43 are fixedly connected to two extension plates 56 by multiple positioning bolts 45; the length of the two extension plates 56 is the same as the length of the main frame 51.

[0048] One of the two extension plates 56 has a plurality of threaded holes 55 evenly provided on its top, and the top ends of the two extension plates 56 are respectively fixedly connected to the ends of the two connecting frames 6 by bolts; the two ends of the two connecting frames 6 that are close to each other are respectively attached to the sides of the four transverse frames 43.

[0049] Both main frames 51 are located between two load-bearing blocks 7, and the two ends of the two main frames 51 are fixedly connected to the two load-bearing blocks 7 respectively; the tops of the two trusses 2 closest to the traction machine 8 are fixedly connected to the bottoms of the two pads 1, and the tops of the two pads 1 are fixedly connected to the bottom ends of the traction machine 8 respectively by bolts.

[0050] By adopting the above technical solution, after loosening multiple positioning bolts 45, the four transverse frames 43 can move laterally along the two main frames 51, which can change the lateral position of the traction machine 8. In conjunction with the threaded cylinder 41 and screw structure 42, the traction machine 8 can move in multiple directions, reducing the difficulty of installing the traction machine 8. The upper slide rail 52 and the two side slide rails 53 can make the transverse frames 43 move more smoothly, and at the same time prevent the transverse frames 43 from shaking or tilting. After tightening multiple positioning bolts 45, the transverse frames 43 can be fixedly connected to the main frame 51, preventing the four transverse frames 43 from moving at will. In addition, the two connecting frames 6 can block the transverse frames 43, further improving the stability of the transverse frames 43.

[0051] The working principle of this utility model is as follows: When installing the traction machine 8, rotating the screw 421 can drive the threaded cylinder 41 to rise and fall, thereby changing the height of the two side frames 3 and the three trusses 2, and thus changing the height of the traction machine 8; after determining the height of the threaded cylinder 41, the fixing bolt 425 is inserted into the insertion hole 424 of the screw 421, the rotating part 422 and the fixing part 423 and the fixing bolt 425 is fixed with the nut 426, so that the fixing bolt 425 can fix the rotating screw 421, prevent the rotating screw 421 from rotating arbitrarily, and ensure the stability of the threaded cylinder 41, which can prevent the height of the traction machine 8 from changing and also prevent the traction machine 8 from tilting;

[0052] Loosening multiple positioning bolts 45 allows the four transverse frames 43 to move laterally along the two main frames 51, changing the lateral position of the traction machine 8. Combined with the threaded cylinder 41 and screw structure 42, this enables the traction machine 8 to move in multiple directions, reducing the difficulty of installation. The upper slide rail 52 and two side slide rails 53 ensure smoother movement of the transverse frames 43 and prevent swaying or tilting. Tightening the multiple positioning bolts 45 secures the transverse frames 43 to the main frames 51, preventing them from moving arbitrarily. Furthermore, the two connecting frames 6 can block the transverse frames 43, further improving their stability.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
