[0001] The invention relates to the technical field of outdoor construction of railway signals, in particular to an angle steel signal eye mold and a drilling device for installing a switch machine. Background Art

[0002] As a key signal infrastructure, the installation standards and processes of switch machines are directly related to the safety of train operation. However, due to the diversity of switch machine models and on-site turnout models, determining the drilling position during turnout construction is both time-consuming and laborious.

[0003] The utility model with authorization announcement number CN217227561U discloses a switch machine installation device, including two symmetrically arranged channel steels 1, each of which is provided with a concrete sleeper installation part 1-1 and a switch machine installation part at both ends, and the channel steel 1 is provided with a plurality of first bolt installation holes 1-2 and a plurality of second bolt installation holes at the concrete sleeper installation part 1-1 and the switch machine installation part, respectively; two channel steel connecting rods 2 are provided on the upper surface of the switch machine installation part, each of which is provided with a plurality of third bolt installation holes 2-1, and there is a gap between the two channel steel connecting rods 2. The channel steel 1 is provided with an insulating rubber plate 3 on the lower surface of the concrete sleeper installation part 1-1. When in use, first drill bolt mounting holes on the channel steel 1, the channel steel connecting rod 2 and the concrete sleeper in advance, then cover the openings of the two channel steels 1 downward on the surfaces of the two adjacent concrete sleepers, and use multiple first bolts to pass through the first bolt mounting holes 1-2 and the concrete sleeper bolt holes to fix the concrete sleeper mounting part 1-1 of the channel steel 1 and the concrete sleeper together; the switch machine is placed on the two channel steel connecting rods 2, and multiple second bolts are used to pass through the switch machine bolt holes, the third bolt mounting holes 2-1 and the second bolt mounting holes to fix the switch machine, the channel steel connecting rod 2 and the switch machine mounting part of the channel steel 1 together. Since the sizes of the concrete sleeper and the switch machine are fixed, holes can be accurately drilled in advance on the channel steel 1 and the channel steel connecting rod 2, which can prevent the deformation of each component and the deviation of the switch machine's action direction over time; and the channel steel 1 has no direct contact with the rail, avoiding the problem of the red light band of the line caused by the short circuit, and the insulating rubber sheet 3 is arranged between the channel steel 1 and the concrete sleeper so as not to fall off, and can play a buffering role to avoid the deformation of the channel steel 1 caused by the vibration of the rail. However, due to the possibility of errors in on-site measurement, the turnout cannot be installed properly after drilling is completed. In order to ensure the accuracy of drilling holes on the rails and improve work efficiency, it is necessary to research and design a set of special molds and matching drilling devices to improve the accuracy of drilling and greatly improve the quality of drilling, so as to solve the drilling and installation problems of the switch installation device in the construction project.

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific examples.

[0028] The portable switch machine is provided with an angle steel eyelet mould and a drilling device, comprising an eyelet mould and a drilling device.

[0029] like Figure 1-Figure 4 As shown, the eyelet mold is made according to the turnout installation drawings and the basic requirements of on-site construction, and is used in conjunction with a drilling device. The eyelet mold includes a base plate 1 and a plurality of C-type clamping devices 4.

The positioning plate 11 is connected to the base plate 1 by screws, and the positioning plate 11 and the base plate 1 of suitable sizes can be selected on-site for installation. The number of the C-type clamping devices 4 is preferably 3. The upper end of the C-type clamping device 4 is a hanging rod, which can be hung on the upper surface of the rail. A long straight rod is provided at one end of the hanging rod. The length of the long straight rod matches the width of the base plate 1, which is used to fit the clamping area 12. A short curved rod is provided at one end of the hanging rod. A locking nut is provided on the short curved rod to support the side wall of the rail for fixing. The width of the base plate 1 matches the 50 rail or 60 rail. When in use, the corresponding clamp is selected according to the model of the rail to be drilled, and hung at the position where the rail needs to be drilled. The end face of the positioning plate 11 matches the shape of the side wall of the 50 rail or 60 rail, which is convenient for positioning and fixing. Different eyelet molds adapt to different rails to ensure the concentricity of the drilling.

[0030] like Figure 5 and Figure 6As shown, the drilling device includes a machine base and a cooling device, and a rail chuck 21, an engine 22, a drilling handle 23 and a drilling machine 24 are installed on the machine base. The engine 22 is provided with a throttle control handle 221, an oil filling screw 222 and an engine switch 223. The engine 22 adopts a high-power engine, and the four-stroke engine meets environmental protection requirements. The engine is equipped with a large-capacity fuel tank to ensure long-term field work oil. The engine 22 is provided with a stepless throttle adjustment to meet the user's arbitrary adjustment. The engine 22 is provided with an overload protection design to ensure that the engine does not stop when the drill bit is in a stagnant state. The engine 22 is connected to and drives the drill bit of the drilling machine 24 to rotate. The drilling machine 24 is installed on the machine base through a slide seat, and the drill bit of the drilling machine 24 is inserted from the positioning hole 12. The drilling handle 23 is connected through a gear rack mechanism and can drive the slide seat to move forward and backward, thereby completing the drilling operation.

[0031] Furthermore, a handle 25 is installed on the base to facilitate transportation.

[0032] Furthermore, the drilling device also includes matching accessory tools, which include a 5mm hexagonal wrench, a 6mm hexagonal wrench, a 4mm hexagonal wrench with a handle, a spark plug wrench with a screwdriver and a brush, which are easy to use.

[0033] Further, such as Fig. 9 As shown, the drilling device also includes two positioning sleeves 5, which are installed on the drilling machine 24 and tightened with special mounting screws of the positioning sleeves 5 to ensure that the heads of the mounting screws all enter the interior of the positioning sleeves. After the installation is completed, the positioning sleeves are placed in the drilling positioning fixture to start drilling.

[0034] Furthermore, the angle steel eyelet mold and drilling device installed on the portable switch machine are light in weight and small in size, and are suitable for single-person operation.

[0035] Furthermore, the portable switch machine is equipped with an angle steel eyelet mold and a unique anti-vibration design of a drilling device, which ensures the stable operation of the machine during operation.

[0036] Furthermore, the portable switch machine is equipped with an angle steel eyelet mold and a drilling device with a short wheelbase, accurate drilling and concentric hole diameters, which can effectively increase the service life of the drill bit by more than 3 times and reduce the pressure on the use of consumables; at the same time, it also greatly improves the drilling quality, and the hole cavity is smooth and free of burrs.

[0037] like Figure 6As shown, when this design is used, the positioning sleeve 5 is installed on the drilling machine 24 and tightened with the special mounting screws for the positioning sleeve; after installation, ensure that the heads of the mounting screws are completely inserted into the positioning sleeve; according to the type of rail, the protruding side of the matching numbering mold 1 is brought into contact with the rail, and after ensuring that the positioning plate 11 is in full contact with the concave surface of the rail, select the corresponding base plate 1 (50 rail corresponds to 50CN base plate 1, 60 rail corresponds to 60CN base plate 1) and hang it on the position where the rail needs to be drilled, and use the C-type clamping device 4 to align with the clamping area 12 of the fixture to install and fix the numbering mold 1, and insert the positioning sleeve 5 on the drilling machine 24 into the positioning hole 13 of the numbering mold.

[0038] Prepare the drilling machine 24, insert the drill bit from the end with the slot, and use the drilling handle 23 to position the central axis 241 of the drilling machine 24, so that the two flat head screws 242 are visible, and there is enough space to install the drill bit. Put the drill bit into the central axis 241, align the slot on the drill bit with the flat head screw 242, and use a 4mm hexagonal wrench to tighten the flat head screw 242 to clamp the drill bit. Install the positioning sleeve 5 on the drilling machine and tighten it with the special mounting screws for the positioning sleeve; after installation, ensure that the heads of the mounting screws are all inside the positioning sleeve.

[0039] The cooling device is of model SR5000, and is composed of a barrel with a hose and a maximum pressure valve. A cooling valve 26 is provided on the drilling machine, and the hose connects the maximum pressure valve and the cooling valve. When drilling, the drilling machine equipped with a drilling cutter automatically controls the flow and stop of the coolant by relying on the pilot drill. The drilling machine 24 equipped with an auger operates to turn the switch wrench 27. The consumption of the coolant depends on the degree of opening of the cooling valve and the pressure in the barrel. Therefore, when the pressure in the barrel reaches the maximum, it is recommended to open the cooling valve slightly; conversely, when the pressure in the barrel is low, the cooling valve should be fully opened. The unique cooling system ensures long-term high-intensity work.

[0040] The drilling machine 24 is designed with a quick installation / detachment structure chuck, which can quickly fix the drilling machine 24 on the machine base, and the central shaft 241 can be completely retracted using the drilling handle 23, such as Figure 7 and 8As shown, the rail clamp 21 includes a fixed clamp arm and a movable clamp arm 273, the middle part of the movable clamp arm 273 is hinged to the upper end of the fixed clamp arm, the lower end of the fixed clamp arm is installed with the positioning sleeve 5 and the eyelet mold 1, the lower end of the movable clamp arm 273 is provided with a clamp, and the upper end of the movable clamp arm 273 is provided with a connecting buckle seat A. The rail clamp 21 is controlled to open and close by a switch wrench 27, and the fixed clamp arm is also provided with a screw 271 and a spring, and the spring connects the upper ends of the fixed clamp arm and the movable clamp arm 273. Place the threaded sleeve 272 on the screw rod 271 at the movable clamping arm 273, turn the handwheel of the switch wrench 27 until the movable clamping arm is fully opened, insert the drill bit of the drilling machine 24 into the positioning hole 13 of the eyelet mold 1, and then press down the handwheel of the switch wrench 27 completely, the eyelet mold 1 will automatically position the drill bit at the desired drilling position, after the drilling is completed, just turn the handwheel of the switch wrench 27 counterclockwise for about two circles, at this time the drilling machine 24 is supported by the drilling handle 23, and then pull the switch wrench 27 towards the operator, the threaded sleeve 272 is disengaged from the connecting buckle seat A of the movable clamping arm 273, the movable clamping arm 273 automatically opens, and the drilling machine is taken out.

[0041] The drilling machine 24 used in this embodiment is a four-stroke gasoline engine, which only uses unleaded conventional gasoline, opens the fuel tank cap, and slightly tilts the drilling machine so that the oil inlet plane faces upward.

[0042] Connect the quick female connector of the hose of the cooling device to the male connector of the cooling valve 26 of the drilling machine 24, turn on the opening switch of the barrel hose, shake the drilling handle 23 to advance the positioning needle to a position that almost touches the rail, press and release the inverted tooth, and restore the drilling handle 23 to its original position, and try to make the drilling handle 23 in the most favorable operating position. Turn the engine switch 8 "ON / OFF" to the "ON" position, put the speed lever in the low speed position, squeeze the oil suction pump 7-10 times to allow the oil to flow fully into the carburetor, and slowly pull the pull rope handle until you feel obvious resistance, which means that the piston has reached the critical compression point, let the pull rope fully retract, and then pull it out quickly, do not pull the pull rope out completely. After the engine starts, hold the handle and let the pull rope retract. After drilling is completed, operate the drilling handle 23 to fully retract the drill bit to the center axis, then put the speed lever in the low speed state, and run at low speed for 2 to 3 minutes before turning the engine switch 8 "ON / OFF" to the "OFF" position to stop the engine.

[0043] This design is light in weight and small in size, suitable for single-person operation; convenient track clamps, fast rail loading and unloading. It has far-reaching significance for accurately determining the drilling position, reducing measurement errors, and improving the drilling quality and installation accuracy of the switch machine.
