Description

Technical Field

[0001] This utility model relates to the field of railway engineering, specifically a drilling device for removing broken screws from railway concrete sleepers. Background Technology

[0002] The company uses 60mm steel rails for its molten iron transport lines. The concrete sleeper pads of these rails are secured with 30mm diameter, 4.8-grade strength bolts. Due to geographical location and track conditions, the molten iron car's running gear is a four-axle type with an axle load of up to 55 tons. During operation, the combined lateral and longitudinal impact forces cause frequent bolt breakage on curved sections, especially in turnout areas. The lengths of the turnout concrete sleepers vary, making them non-uniform; purchasing a single sleeper is difficult and expensive. The industry lacks the technology to directly remove broken bolts from 60mm steel rail concrete sleepers, and has traditionally replaced them on-site by purchasing new sleepers. On-site sleeper replacement requires cleaning the ballast, using a crane to remove the sleeper, installing it, backfilling and compacting the ballast—a large-scale, time-consuming, and labor-intensive process. Given the fast pace of molten iron production, prolonged construction negatively impacts operations.

[0003] To address the aforementioned problem, a drilling device for removing broken screws from railway concrete sleepers is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a drilling device for removing broken screws from railway concrete sleepers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for removing broken screws from railway concrete sleepers, comprising a fixing device and a drilling machine.

[0006] The drilling machine consists of a base, a column, a sliding device, a drive device, and a drill bit. The base extends along a first direction, and the column extends along a second direction, which is perpendicular to the first direction. The base and the end of the column near the rail are connected. The sliding device consists of a lifting body and a lifting operating rod. The lifting body is sleeved on the column, and the sliding of the lifting body on the column is controlled by the swing of the lifting operating rod. The drive device is fixed in parallel to one side of the lifting body along the first direction. The fixed end of the drill bit is fixed to the end of the drive device near the rail, and the drill bit is positioned directly above the concrete sleeper. The drilling direction of the drilling machine is perpendicular to the first direction. The drilling machine is connected to the rail through a fixing device, and the fixing device and the rail are arranged along the second direction.

[0007] The aforementioned drilling device, through the installation of a fixing device and a drilling machine, connects the drilling machine to the rail when a bolt on the concrete sleeper of the rail breaks. The drill bit of the drilling machine is then aligned directly above the broken bolt on the concrete sleeper to complete the drilling operation. In the design scheme of this utility model, preferably, the broken bolt on the concrete sleeper can be replaced without replacing the concrete sleeper, thus overcoming the disadvantages of traditional processes such as large construction volume, long operation time, and high manpower consumption.

[0008] Preferably, in this technical solution, a groove extending in the second direction is provided in the middle position of the base, the end of the column near the rail extends into the groove, and the base is connected to the column by bolts.

[0009] The above-mentioned groove is set on the base to ensure that the column will not shift on the base, and the base and column are connected by bolts, which can be disassembled and replaced at any time.

[0010] Preferably, in this technical solution, the fixing device includes a base plate and a clamping device. The extension direction of the base plate is perpendicular to the extension direction of the rail, and the base plate is arranged on the lower side of the rail. The drilling machine is installed on the base plate, and the base plate is connected to the rail through the clamping device. The base plate and the clamping device are fixedly connected.

[0011] The aforementioned fixing device includes a base plate and a clamping device, which connects the drilling machine to the rail, thereby positioning the drill bit of the drilling machine at the hole position for the concrete sleeper bolt drilling, thus improving the stability of the device.

[0012] Preferably, in this technical solution, the clamping device includes a first fixing plate and a second fixing plate, which are disposed on the base plate. The first fixing plate includes a first column and a first cantilever, the extension direction of the first cantilever being perpendicular to the extension direction of the rail. The first column, the first cantilever, and the rail form a slot for accommodating the rail. The first end of the first column is connected to the base plate, and the second end of the first column is connected to the fixed end of the first cantilever. The mounting end of the first cantilever has a first hole in the vertical direction, and the first hole is directly opposite the concrete. Above the sleeper breakage screw; the second fixing plate includes a second column and a second cantilever, the extension direction of the second cantilever is perpendicular to the extension direction of the rail, the second column, the second cantilever and the rail form a slot for accommodating the rail, the first end of the second column is connected to the base plate, the second end of the second column is connected to the fixing end of the second cantilever, the mounting end of the second cantilever has a pre-set second hole in the vertical direction, and the second hole is directly above the sleeper breakage screw; the fixing device is connected to the rail by bolts extending into the first hole and the second hole respectively.

[0013] Preferably, in this technical solution, the base plate and the clamping device are connected by welding, or the base plate and the clamping device are an integral structure.

[0014] In this preferred embodiment, the base plate has a first bolt hole, and the base has a second bolt hole that mates with the base plate. Bolts extend into the first bolt hole and the second bolt hole to connect the base plate and the base.

[0015] Preferably, in this technical solution, the drill bit is a hollow drill bit, and the diameter of the drill bit can be adjusted.

[0016] Analysis shows that the present invention provides a drilling device for removing broken screws from railway concrete sleepers, including a fixing device and a drilling machine. The base extends along a first direction, and the column extends along a second direction, which is perpendicular to the first direction. The base is connected to the end of the column near the rail. The sliding device consists of a lifting body and a lifting operating rod. The lifting body is sleeved on the column, and the sliding of the lifting body on the column is controlled by the swing of the lifting operating rod. The driving device is fixed in parallel to one side of the lifting body along the first direction. The fixed end of the drill bit is fixed to the end of the driving device near the rail, and the drill bit is positioned directly above the concrete sleeper. The drilling direction of the drilling machine is perpendicular to the first direction. The drilling machine is connected to the rail through the fixing device, and the fixing device and the rail are arranged along the second direction. The above drilling device connects the drilling machine to the rail via a fixing device, thereby ensuring that the drill bit of the drilling machine is positioned on the bolt hole of the concrete sleeper, which facilitates the subsequent removal of the bolt. When it is necessary to remove the bolts of the concrete sleeper in different positions, it is only necessary to move the fixing device to remove the broken bolts in different positions, thus improving the adaptability of the device.

[0017] Compared with the closest existing technology, the technical solution provided by this utility model has the following advantages:

[0018] 1. Existing technologies require on-site replacement of concrete sleepers, which necessitates cleaning the ballast, using a crane to remove the sleepers, installing new sleepers, backfilling and compacting the ballast. This process is labor-intensive, time-consuming, and resource-intensive, impacting the fast-paced production of iron ore lines. This invention uses a fixing device to secure the drilling machine at the designated drilling position. The height of the lifting body is adjusted via a sliding device using a lifting lever. This adjustment, in turn, adjusts the position of the drive unit and drill bit, activating the drilling machine to remove broken screws from the concrete sleeper. The combined action of the drilling machine and the fixing device allows for screw removal without removing the sleeper, significantly improving the efficiency of replacing broken screws.

[0019] 2. In view of the existing traditional sulfur anchoring process (which cannot be used for 60mm concrete sleepers), this utility model adjusts the size of the drill bit to achieve concrete sleepers of different specifications. Compared with the traditional sulfur anchoring process, this utility model is more economical, environmentally friendly and safe. Attached Figure Description

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0028] like Figure 1 As shown, according to an embodiment of the present invention, the present invention provides a technical solution: a drilling device for removing broken bolts from railway concrete sleepers, comprising a fixing device and a drilling machine. The drilling machine consists of a base 1, a column 2, a sliding device 3, a driving device 4, and a drill bit 5. The base 1 extends along a first direction, and the column 2 extends along a second direction, which is perpendicular to the first direction. The base 1 and the column 2 are connected to the end near the rail to ensure that the base 1 and the column 2 are perpendicular, thereby ensuring that the drilling machine can be positioned above the broken bolts from the concrete sleeper.

[0029] The sliding device 3 consists of a lifting body 6 and a lifting operating rod 7. The lifting body 6 is sleeved on the column 2, and the sliding of the lifting body 6 on the column 2 is controlled by the swing of the lifting operating rod 7. While reducing the difficulty of operation, the lifting operating rod 7 improves the adaptability to concrete sleepers of different positions or specifications.

[0030] The drive device 4 is fixed in parallel to one side of the lifting body 6 along the first direction. The fixed end of the drill bit 5 is fixed to the end of the drive device 4 near the rail, and the drill bit 5 is positioned directly above the concrete sleeper. The drilling direction of the drilling machine is perpendicular to the first direction to ensure that the drilling direction of the drilling machine is always directly facing the broken screw of the concrete sleeper.

[0031] The drilling machine is connected to the rail via the fixing device, and the fixing device and the rail are arranged along a second direction to improve the stability of the drilling device.

[0032] Furthermore, a groove extending in the second direction is provided in the middle position of the base 1, and one end of the column 2 near the rail extends into the groove, and the base 1 is connected to the column 2 by bolts; by providing a groove on the base 1, the stability of the drilling device is further improved.

[0033] Furthermore, the fixing device includes a base plate 8 and a clamping device; the extension direction of the base plate 8 is perpendicular to the extension direction of the rail, and the base plate 8 is arranged on the lower side of the rail; the drilling machine is installed on the base plate 8; the base plate 8 is connected to the rail through the clamping device; the base plate 8 and the clamping device are fixedly connected.

[0034] As can be seen from the above analysis, the fixing device includes a base plate 8 and a clamping device, which further strengthens the connection between the drilling machine and the rail, and improves the stability of the drilling device.

[0035] Furthermore, such as Figure 2 and Figure 3 As shown, the clamping device includes a first fixing plate 9 and a second fixing plate 10.

[0036] The first fixing plate 9 and the second fixing plate 10 are disposed on the base plate 8.

[0037] The first fixing plate includes a first column 11 and a first cantilever 12. The extension direction of the first cantilever 12 is perpendicular to the extension direction of the rail. The first column 11, the first cantilever 12, and the rail form a slot for accommodating the rail. The first end of the first column 11 is connected to the base plate 8, and the second end of the first column 11 is connected to the fixing end of the first cantilever 12. The mounting end of the first cantilever 12 has a first hole 13 in the vertical direction, and the first hole 13 is directly above the concrete sleeper breakage screw. The second fixing plate 10 includes a second column 14 and... The second cantilever 15 extends perpendicularly to the rail. The second column 14, the second cantilever 15, and the rail form a groove to accommodate the rail. The first end of the second column 14 is connected to the base plate 8, and the second end of the second column 14 is connected to the fixed end of the second cantilever 15. The mounting end of the second cantilever 15 has a pre-set second hole 16 in the vertical direction, and the second hole 16 is directly above the broken bolt of the concrete sleeper. The clamping device further improves the connection between the rail and the fixing device in the above manner, and the structure is simple.

[0038] The fixing device is connected to the rail by bolts inserted into the first hole 13 and the second hole 16 respectively, which facilitates the disassembly of the fixing device and the rail.

[0039] Furthermore, the base plate 8 and the clamping device are connected by welding, or the base plate 8 and the clamping device are an integral structure.

[0040] As can be seen from the above analysis, the base plate 8 and the clamping device are connected by welding, which improves the connection strength between the base plate 8 and the clamping device and simplifies the processing; or, the base plate 8 and the clamping device adopt an integral structure, which improves the overall integrity of the fixing device.

[0041] Furthermore, the base plate 8 is provided with a first bolt hole 17, and the base 1 is provided with a second bolt hole 18 that mates with the base plate 8. Bolts extend into the first bolt hole 17 and the second bolt hole 18 to connect the base plate 8 and the base 1. This facilitates the disassembly of the drilling machine and the fixing device, and allows for the replacement of broken screws on different concrete sleepers. If the drilling machine or the fixing device is damaged, it is easy to disassemble and replace it.

[0042] Furthermore, the drill bit 5 is a hollow drill bit, and the diameter of the drill bit 5 can be adjusted; the purpose is to adapt to different specifications of concrete sleeper screws and improve the adaptability of the device.

[0043] This invention removes the outer nylon sleeve along with the broken screw from the drilled concrete pillow. After removing the broken screw and the outer nylon sleeve, a new nylon sleeve is fixed with anchoring adhesive. After 24 hours, once the nylon sleeve is firmly attached, a pad is directly installed to tighten the new screw.

[0044] The process of removing the broken screw from the concrete sleeper using this device is as follows:

[0045] In the preparation stage, a fixing device is connected to the rail of the concrete sleeper with the broken screw, and the drilling machine is fixed on the fixing device. The drill bit of the drilling machine is positioned directly above the broken screw of the concrete sleeper. The position of the lifting body 6 is adjusted by adjusting the lifting operating lever 7, thereby adjusting the distance between the drill bit 5 and the broken screw. In the working stage, the driving device provides power to the drill bit 5, and the drill bit 5 is inserted into the broken screw. The broken screw and the outer nylon sleeve are removed by direct drilling.

[0046] In summary, the drilling device of this utility model achieves the following technical effects:

[0047] 1) In the existing technology, on-site replacement of concrete sleepers requires cleaning the ballast, using a crane to remove the concrete sleepers, installing the new sleepers, backfilling the ballast, and compacting it. This involves a large amount of work, takes a long time, and consumes a lot of manpower and resources. The production pace of iron ore lines is fast, and long-term construction will affect production. This utility model removes the broken screws by directly drilling holes, avoiding the need to replace the entire concrete sleeper, reducing costs, and is simple to operate.

[0048] 2) Traditional sulfur anchoring process fixes the screws in place at once, making it impossible to carry out normal maintenance later. This utility model removes broken screws by drilling. After installing new screws, if the new screws become loose or break, they can still be removed and replaced again.

[0049] 3) The drilling machine is connected to the rail via a fixing device, allowing it to be moved at any time to remove broken bolts from different concrete sleepers.

[0050] 4) A drilling machine is used to directly drill and remove the broken screws from the concrete pillow, which improves the efficiency of removing broken screws, reduces costs, and allows for reuse, thus increasing the flexibility of the device.

[0051] 5) The fixing device consists of a base plate 8 and a clamping device, which further improves the stability of the device. The structure is simple and strengthens the connection stability between the drilling machine and the rail.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
