Technical Field
[0001] This utility model relates to the field of crane technology, and in particular to a combined bracket for transmission components of a T-type steering box. Background Technology
[0002] Currently, in the hoisting mechanism of a crane, the lifting device is generally moved by a drum via a wire rope. During the actual operation of the drum, it is usually necessary to limit the speed of the drum and measure the real-time position of the lifting device. The method used is usually to install a T-shaped steering box at the end of the drum's rotating shaft, which can connect to transmission components (overspeed switch, rotation limit switch, and position encoder). The T-shaped steering box connects the drum's rotating shaft and the transmission components through a coupling, and is mounted on the crane via a base.
[0003] like Figure 17 As shown, in existing cranes, different types of transmission components need to be fixed to the crane using their respective mounting brackets. To ensure reliability, the mounting brackets are usually welded together, resulting in a large amount of welding work. Furthermore, the presence of other crane components on-site can easily cause interference, making installation impossible. Additionally, coaxiality needs to be adjusted according to the actual working conditions, making installation difficult. After installation, any subsequent modifications are extremely cumbersome. When replacing a transmission component of a certain model with another, the input shaft height of the newly replaced component generally differs significantly from the original model. To ensure coaxiality, the mounting bracket needs to be modified, or even the original mounting bracket needs to be removed and a new one welded on. This presents problems such as poor economy, timeliness, and high installation difficulty. Summary of the Invention
[0004] This utility model provides a combined bracket for the transmission components of a T-type steering box to overcome the above-mentioned technical problems.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A combined bracket for a transmission element of a T-type steering box includes: a steering box base, the top surface of which is used to mount the T-type steering box; two or three mounting surfaces are provided on the outer side of the steering box base; a transmission element mounting seat can be detachably connected to the mounting surfaces; the transmission element mounting seat can adjust its mounting position relative to the mounting surfaces in the vertical direction; and the transmission element mounting seat includes a rotary limit switch mounting seat, an encoder mounting seat, and an overspeed switch mounting seat.
[0007] Furthermore, it also includes a longitudinal fixed support and a triangular support member. The triangular support member has a horizontal part and a vertical part fixed on the horizontal part. The bottom surface of the steering box base is detachably connected to the horizontal part, and the side surface of the longitudinal fixed support is detachably connected to the vertical part.
[0008] Furthermore, it also includes a protective cover plate, which is mounted on the top surface of the steering box base by studs, and a space for accommodating the T-shaped steering box is formed between the protective cover plate and the top surface of the steering box base.
[0009] Furthermore, each of the transmission element mounting bases is provided with a base connection hole for connecting to the steering box base and a transmission element connection hole for connecting the transmission element. The base connection hole is an elongated oval hole extending in the vertical direction, and the transmission element connection hole is a bolt hole or an elongated oval hole extending in the horizontal direction.
[0010] Furthermore, when the steering box base has two mounting surfaces on its outer side, the steering box base includes a main body, which is a square tube, and the square tube has two mounting surfaces; when the steering box base has three mounting surfaces on its outer side, the steering box base includes a main body and a connector detachably connected to the main body, the main body is a square tube, the square tube has two mounting surfaces, the connector is disposed at one end of the square tube, and the connector has one mounting surface.
[0011] Furthermore, the steering box base is provided with a first connecting hole, which is an elongated hole extending in the horizontal direction.
[0012] Furthermore, the vertical part is provided with a second connecting hole, which is an elongated hole extending in the vertical direction.
[0013] Furthermore, the longitudinal fixed support has multiple rows of adjustment holes along the vertical direction for connecting with the vertical part.
[0014] Furthermore, bolt holes are provided on the mounting surface.
[0015] Beneficial effects: The combined bracket for transmission components of a T-type steering box provided by this utility model provides an installation foundation for the T-type steering box through the top surface of the steering box base, while the mounting surface on the outer side of the steering box base provides an installation foundation for the transmission component mounting seat. This means that each transmission component is no longer installed on a separate mounting seat fixed to the crane, but is set together with the T-type steering box on the steering box base. Only the steering box base needs to be fixed to the crane to provide a reliable installation foundation for the T-type steering box and transmission components, thereby greatly reducing the amount of welding work and requiring less floor space, ensuring economy and timeliness.
[0016] Furthermore, by employing a detachable transmission element mounting base, the positions of the transmission elements can be interchanged on different mounting surfaces, effectively avoiding interference. When the transmission element model needs to be changed, only the transmission element mounting base needs to be replaced, resulting in low cost. In addition, by adjusting its position relative to the mounting surface in the vertical direction, the transmission element mounting base ensures that the coaxiality of the newly replaced transmission element and the T-type steering box is easily adjusted.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0037] This embodiment provides a combined bracket for the transmission components of a T-type steering gearbox, such as... Figures 1 to 3 As shown, it includes: a steering box base 1, the top surface of which is used to install a T-shaped steering box 10, and two or three mounting surfaces 5 on the outer side of the steering box base 1. A transmission element mounting seat can be detachably connected to the mounting surface 5. The transmission element mounting seat can adjust its installation position relative to the mounting surface 5 in the vertical direction. The transmission element mounting seat includes a rotary limit switch mounting seat 2, an encoder mounting seat 3, and an overspeed switch mounting seat 4.
[0038] This embodiment provides a combined bracket for the transmission components of a T-type steering box. The top surface of the steering box base 1 provides an installation foundation for the T-type steering box 10, while the mounting surface 5 on the outer side of the steering box base 1 provides an installation foundation for the transmission component mounting seat. This means that the transmission components are no longer installed on separate mounting seats fixed to the crane, but are instead set together with the T-type steering box 10 on the steering box base. Only the steering box base 1 needs to be fixed to the crane to provide a reliable installation foundation for the T-type steering box 10 and the transmission components, thereby greatly reducing the amount of welding work and requiring less floor space, ensuring economy and timeliness.
[0039] Furthermore, by employing a detachable transmission element mounting base, the positions of the transmission elements can be interchanged on different mounting surfaces, effectively avoiding interference. Figure 15 and Figure 16For example, simply swapping the positions of encoder mounting base 3 and overspeed switch mounting base 4 can prevent interference zone 20 between overspeed switch 17 and obstacle 19.
[0040] When the transmission component needs to be changed, only the transmission component mounting base needs to be replaced, which is inexpensive. In addition, by adjusting its position relative to the mounting surface in the vertical direction, the coaxiality of the newly replaced transmission component and the T-type steering box 10 can be easily adjusted.
[0041] Specifically, such as Figures 1 to 4 As shown, it also includes a longitudinal fixed support 6 and a triangular support 7. The triangular support 7 has a horizontal part 71 and a vertical part 72 fixed on the horizontal part 71. The bottom surface of the steering box base 1 is bolted to the horizontal part 71 (a spring washer and a flat washer can be added to prevent loosening). The side of the longitudinal fixed support 6 is bolted to the vertical part 72 (a spring washer and a flat washer can be added to prevent loosening).
[0042] In this embodiment, the longitudinal fixed support 6 can be a channel steel with an adjustment hole 61. The bottom of the channel steel is welded to the crane. The channel steel should have a certain amount of redundancy. During welding, the bottom of the channel steel can be cut according to the actual site conditions.
[0043] Specifically, such as Figure 1 As shown, it also includes a protective cover plate 8, which is mounted on the top surface of the steering box base 1 by studs 18, and a space for accommodating the T-shaped steering box 10 is formed between the protective cover plate 8 and the top surface of the steering box base 1.
[0044] In this embodiment, as Figure 2 As shown, the stud 18 is a hexagonal stud with internal threads. The two ends of the stud 18 are connected to the top surface of the protective cover plate 8 and the steering box base 1 by bolts (spring washers and flat washers can be added to prevent loosening). The stud 18 is used to support the protective cover plate 8, and the protective cover plate 8 protects the T-shaped steering box 10.
[0045] Specifically, such as Figures 5 to 10 As shown, the transmission element mounting base is provided with a base connection hole 13 for connecting the steering box base 1 and a transmission element connection hole 14 for connecting the transmission element. The transmission element mounting base is bolted to the transmission element and the steering box base 1 (spring washers and flat washers can be added to prevent loosening). The base connection hole 13 is an elongated hole extending in the vertical direction, and the transmission element connection hole 14 is a bolt hole or an elongated hole extending in the horizontal direction. The elongated hole can facilitate the adjustment of the position of the transmission element mounting base and the transmission element.
[0046] Figures 5 to 8Different rotary limit switch mounting bases 2 are used to install different models of rotary limit switches 15. Figure 10 Encoder mounting bracket 3 is used to mount encoder 16. Figure 9 The overspeed switch mounting base 4 is used to install the overspeed switch 17. The transmission elements (rotary limit switch 15, encoder 16 and overspeed switch 17) are not limited to the form shown in the figure, which is only an example.
[0047] Specifically, when the outer side of the steering box base 1 is provided with two mounting surfaces 5 (applicable to T-type steering boxes 10 with one input shaft and two output shafts, the type of transmission element can be reduced by one; for safety reasons, the encoder 16 can usually be omitted), such as Figure 11 As shown, the steering box base 1 includes a main body 11, which is a square tube. The square tube has two mounting surfaces 5, and the mounting surfaces 5 have bolt holes. The T-shaped steering box 10 and the transmission element mounting seat are connected through bolts in the bolt holes.
[0048] When the outer side of the steering box base 1 is provided with three mounting surfaces 5 (applicable to a T-type steering box 10 with one input shaft and three output shafts), such as Figure 4 As shown, the steering box base 1 includes a main body 11 and a connector 12 detachably connected to the main body 11, such as... Figure 11 As shown, the main body 11 is a square tube with two mounting surfaces 5. The connector 12 is fixed to one end of the square tube by bolts (spring washers and flat washers can be added to prevent loosening). Figure 12 As shown, the connector 12 has a mounting surface 5, and the mounting surface 5 has bolt holes. The connector is connected to the T-shaped steering box 10 and the transmission element mounting seat through bolts in the bolt holes.
[0049] Preferably, such as Figure 11 As shown, the steering box base 1 is provided with a first connecting hole 9, which is an elongated hole extending horizontally, such as... Figure 13 As shown, the vertical part 72 is provided with a second connecting hole 73. The second connecting hole 73 is an elongated hole extending in the vertical direction. The elongated hole can facilitate the position adjustment of the transmission element mounting base and the triangular support 7, thereby facilitating the adjustment of coaxiality.
[0050] Preferably, such as Figure 14 As shown, the longitudinal fixed support 6 has multiple rows of adjustment holes 61 for connecting with the vertical part 72 in the vertical direction. The adjustment holes 61 facilitate the position adjustment of the triangular support 7. The adjustment holes 61 are used in conjunction with the second connecting hole 73 to improve the position accuracy of the triangular support 7.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
