Description

Technical Field

[0001] This utility model belongs to the field of rail drilling technology, and specifically relates to a drilling machine for rail components used in rail transit. Background Technology

[0002] In railway construction, cooperating with track maintenance to replace long rails is a common task for electrical maintenance personnel. When replacing long rails, it is necessary to wait for track maintenance to complete stress relief before drilling holes, inserting plugs, installing capacitors, and connecting lead wires to the new rails.

[0003] During long-term drilling operations, it was found that the minimum spacing between two adjacent sets of drill holes on the rail is 320mm, while the minimum space size of the drilling machine is 610mm. In order to ensure the stability of the drilling process, a special rail drilling machine and a rail clamping device are required to be used together. The rail clamping device is used to clamp the bottom end face of the rail, which means that drilling can only be performed in the middle of the rail web in the transverse direction, resulting in certain limitations in its function.

[0030] like Figure 1-5 As shown, this embodiment provides a drilling machine 100 for rail components used in rail transit, including two sets of adjacent clamping devices 10. Each clamping device 10 includes a clamping base 101, which is provided with a placement platform 103. The placement platform 103 divides the clamping base 101 into upper and lower parts. The lower part is a cavity 105, and a placement plate 107 for placing the drilled component is welded and installed inside the cavity 105. The placement plate 107 is generally concave.

[0031] Other mounting plates that can accommodate drilled parts are also acceptable, such as rectangular ones.

[0032] In this embodiment, it can be seen that two adjacent clamping devices 10 are connected by the placement plate 107 to form a whole. The placement plate 107 with a concave shape is used to place the power system 301 of the drilling part. During installation, the power system 301 can be fixedly installed on the bottom end face and the two side end faces of the placement plate 107 by fastening screws.

[0033] For drilling parts, any commonly available drilling parts on the market will suffice, such as those driven by an electric motor or those with internal combustion engines. They will not be described in detail here.

[0034] Furthermore, the clamping device 10 also includes a baffle 104, which consists of two sets arranged opposite to each other and is bolted to the side end face of the clamping seat 101. The baffle 104 is located on the placement platform 103 between the two sets of oppositely arranged baffles 104 and is used to place the rail 20 to be drilled.

[0035] Furthermore, each of the two adjacent sets of baffles 104 is equipped with oppositely arranged clamping wheels 102, which are fixed by fasteners 50, and the two sets of clamping wheels 102 lock the side end face of the rail 20 placed on the placement platform 103.

[0036] Furthermore, the fastener 50 includes an adjusting screw 501, which passes through the baffle 104 and is equipped with a clamping wheel 102. The two ends of the adjusting screw 501 are threadedly connected to adjusting nuts 502, which are used to fix the fastener.

[0037] In this embodiment, the adjusting screw is used in conjunction with the adjusting threaded hole of the baffle to form a helical motion. In order to improve the clamping of the side end face of the rail 20, the outer wall of the clamping wheel 102 is provided with a friction end with concave and convex shapes, thereby increasing the friction force when clamping and locking the clamping wheel.

[0038] The drilling machine 100 for rail components used in rail transit provided in this embodiment adds a concave placement plate 107 inside the cavity. The height between the top end face of the placement platform and the bottom end face of the placement plate 107 is L1, and the height of the concave groove of the placement plate 107 is L2, and L1-L2= 90 ± 0.1 mm. The connecting plate 106, which is fixedly connected to the top end face of the power system 301, is fixedly installed on the horizontal end face of the placement plate 107 located in the cavity 105 by fastening bolts, so that the height of the power system is much lower than the bottom end face of the placement platform.

[0039] This allows the drilling component and clamping wheel to be at different heights when the rail is placed on the platform and clamped by the baffle and clamping components. This eliminates the height limitation of the drilling component and eliminates the need to consider the spatial dimensions of the drilling component. When drilling, only the position of the rail on the platform needs to be moved.

[0040] Furthermore, a support plate 607 is provided on the front end face of the baffle 104, and a bearing seat is provided on the support plate 607. A bearing for connecting and installing the shaft 606 is provided inside the bearing seat. During installation, it is necessary to ensure that the bearing seat and the support plate are fixed by bolts, and to ensure that the flatness of the support plate and the preload of the bolts are uniform to avoid deformation.

[0041] Furthermore, the shaft and the inner ring of the bearing are fitted with an interference fit. The installation of the shaft, bearing and bearing housing is existing technology and will not be described in detail here.

[0042] Furthermore, a sleeve 605 is installed on the outside of the mounting shaft 606 by press fitting or heat fitting, and a clamping plate 601 integrally formed therewith is provided on the outer wall of the sleeve 605. The clamping plate 601 is made of stainless steel plate and is formed by multiple bending. When the rail is clamped, the clamping plate 601 also includes a base plate 604 arranged parallel to the rail.

[0043] Furthermore, a pressing plate 6071 is welded to the end face of the support plate 607 away from the mounting shaft 606, and a threaded hole is provided on the pressing plate 6071, and a threaded rod 608 is threadedly connected in the threaded hole. A fixing nut 609 is threadedly connected to the threaded rod 608 located on the upper and lower end faces of the pressing plate 6071.

[0044] In this embodiment, the rail is placed on the placement platform 103 (when placing the rail, it can be placed upright and holes can be drilled on the side end face of the rail, or it can be rotated 90° to place the rail so that holes can be drilled on both the upper and lower end faces of the rail). The angle of the clamping plate 601 is adjusted by turning the handle 603 so that the bottom plate of the clamping plate 601 is inserted below the bottom end face of the rail. Then, when the adjusting screw drives the clamping wheel 102 to approach the end face of the rail, the rail is clamped.

[0045] At the same time, by loosening the fixing nut 609 and rotating the threaded rod 608, the threaded rod moves toward the top end face of the rail until the bottom end face of the threaded rod abuts against the top end face of the rail. Then, the fixing nut 609 is tightened, thereby clamping the rail and maintaining the stability of the rail during the drilling process.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
