Description

Technical Field

[0001] The disclosed embodiments relate to the technical field of rail drilling devices, and in particular to an F-rail row drilling vehicle. Background Art

[0002] The F-rail track has the function of supporting the maglev vehicle, bearing the suspension force, guiding force and traction force of the vehicle, and is the basis for the suspension and travel of the maglev train. The F-rail track consists of the F-rail, sleepers and fasteners. A continuous aluminum induction plate is laid on the F-rail, and the aluminum induction plate usually needs to be fixed on the F-rail by screws. Therefore, a large number of group drilling operations are required during the processing of the F-rail track.

[0003] Currently, there are several ways to drill holes on F rails: (1) using a portable and movable magnetic drill; (2) using fixed equipment such as a drilling machine; and (3) using a large CNC machine tool for drilling.

[0004] Since there are a large number of holes on the rail, using a portable magnetic drill to drill holes requires workers to first draw lines to confirm the drilling position, and then drill manually by constantly adjusting the position of the magnetic drill, which is labor-intensive. When drilling holes using a fixed drilling machine, the F-rail needs to be constantly moved to adjust the drilling position. Since the F-rail is heavy and large in size, it is extremely inconvenient to move. If a large CNC machine tool is used for tapping operations, the processing cost is high.

[0005] Therefore, it is necessary to improve one or more problems existing in the above-mentioned related technical solutions.

[0055] This example embodiment provides an F-track rail row drilling vehicle, please refer to Figure 1 , may include: a vehicle body assembly 1, a wheel assembly 2, a brake assembly 3, a handle assembly 4, a locking pin assembly 5 and a spindle assembly 6.

[0056] Specifically, a linear guide rail 13 is provided on the front end surface of the vehicle body assembly 1, and the linear guide rail 13 is used to install the spindle assembly 6. There may be two linear guide rails 13, which are arranged in parallel.

[0057] The wheel assembly 2 is arranged on the lower end surface of the vehicle body assembly 1, and is used for traveling on the F rail 10. The brake assembly 3 is arranged on the vehicle body assembly 1, and is used for braking the drilling vehicle to make it in the drilling position of the F rail 10.

[0058] The handle assembly 4 is mounted on the front end surface of the vehicle body assembly 1 and is located on one side of the linear guide rail 13. The handle assembly 4 includes: a handle 41, a rotating shaft 42, a bearing 45 and a gear 44. One end of the rotating shaft 42 is fixedly connected to the handle 41, and the other end is fixedly connected to the gear 44. The rotating shaft 42 is arranged on the front end surface of the vehicle body assembly 1 through the bearing 45.

[0059] The locking pin assembly 5 is disposed on the side end surface of the vehicle body assembly 1 adjacent to the linear guide rail 13 , and is used to lock and release the handle 41 .

[0060] The spindle assembly 6 is arranged on the front end surface of the car body assembly 1. The spindle assembly 6 includes: a mounting plate 61, a rack 62, a slider 63 and a plurality of drill bit assemblies. Specifically, the rack 62 and the slider 63 are both fixedly mounted on the back of the mounting plate 61, the rack 62 is meshed with the gear 44, and the slider 63 is slidably connected with the linear guide rail 13. The plurality of drill bit assemblies are all fixedly mounted on the front of the mounting plate 61, and are used for drilling holes in the F rail 10 row.

[0061] The working process of the F-track drilling vehicle in this application is:

[0062] Move the F-rail drilling vehicle to the position of the F-rail 10 that needs to be drilled, and brake it with the brake assembly 3 to prevent the vehicle body from moving. Turn the handle 41, the handle 41 drives the spindle assembly 6 to move down to the rail, and the handle 41 is limited on the lock pin assembly 5 to prevent the handle 41 from changing its position, and then start the drill assembly to drill holes in the rail.

[0063] In this embodiment, when the drilling vehicle is moving on the F rail 10, the brake assembly 3 can be used to brake the drilling vehicle to prevent the vehicle from moving and improve the drilling quality; the rotation of the handle 41 in the handle assembly 4 is used to drive the upper and lower positions of the drill bit assembly to achieve the drilling operation, and the handle 41 can be limited by the pin assembly 3 to prevent the handle 41 and the drill bit assembly from moving, thereby ensuring the drilling quality; by setting up multiple drilling assemblies, multiple holes can be opened on the rail row at one time, thereby improving the drilling efficiency.

[0064] Below, the structures of the various components of the F-rail row drilling vehicle of the present application are described in more detail.

[0065] 1. Body components 1

[0066] like Figure 1 , Figure 2 and Figure 3 As shown, the vehicle body assembly 1 includes: a box-type frame 11, a handle 12 and a linear guide 13. The box-type frame 11 includes: an end plate 111, a side plate 112, a base plate 113 and a support plate 114. The end plate 111, the side plate 112 and the base plate 113 enclose the box-type frame 11. The support plates 114 are located at both ends below the base plate 113 and are arranged in pairs for mounting the load-bearing wheel set 22. The F-rail track row includes: an F-rail 10 and a sleeper 20. A continuous aluminum induction plate 30 is laid on the F-rail 10. The drilling vehicle travels on the F-rail 10 to perform drilling operations on the aluminum induction plate 30.

[0067] Optionally, the bottom of the side plate 112 is processed with two guide wheel assembly installation grooves along the length direction, and the support plate 114 is processed with an auxiliary load-bearing wheel assembly installation groove. The handle 12 is installed at the middle position of the end plate 111 and the side plate 112 respectively, and there are two linear guide rails 13, which are symmetrically arranged vertically along the width of the end plate 111.

[0068] 2. Wheel assembly 2

[0069] like Figure 3 , Figure 4 and Figure 5 As shown, the wheel assembly 2 includes two guide wheel groups 21 and an auxiliary load-bearing wheel group 22. The two guide wheel groups 21 are respectively installed in the wheel group installation grooves of the side plates 112 of the box-type frame 11, and the auxiliary load-bearing wheel group 22 is installed in the wheel group installation groove of the support plate 114 of the box-type frame 11.

[0070] The guide wheel group 21 includes: a guide wheel 211, a wheel axle 212, a second bearing 213, an axle end retaining ring 214 and a second bearing spacer 215. The guide wheel 211 has raised rims at both ends, which play a guiding and limiting role. Rectangular surfaces are processed on the cylindrical surfaces at both ends of the wheel axle 212. During installation, the plane of the wheel axle 212 is combined with the plane of the wheel group mounting groove of the side plate 112 of the box-type frame 11, and there are shoulder limits at both ends of the wheel axle 212 to ensure that the wheel axle 212 does not rotate or move axially during operation. Similarly, the auxiliary load-bearing wheel group 22 has the same structure as the guide wheel group 21. The wheels of the auxiliary load-bearing wheel group 22 do not have rims, and the auxiliary load-bearing wheel group 22 only plays a load-bearing role; the auxiliary load-bearing wheel group 22 is installed in the wheel group mounting groove of the two support plates 114 of the box-type frame 11. Figure 3 As shown, the auxiliary load-bearing wheel set 22 is located between the two guide wheel sets 21 with equal spacing, and the guide wheel set 21 and the auxiliary load-bearing wheel set 22 have the same wheel surface height after installation, ensuring that the wheel surfaces can contact the track during use.

[0071] 3. Brake components 3

[0072] like Figure 6-Figure 9 As shown, the brake assembly 3 includes: a brake frame 31, an electromagnet mounting seat 32, a brake shaft 33, a DC electromagnet 34, a spring 35, a clamping nut 36 and a handle 37.

[0073] The brake frame 31 includes: a plate 1 311, a stiffening rib 312, a plate 2 313 and a guide sleeve 314. The electromagnet mounting seat 32 includes an electromagnet connecting plate 321 and a guide column 322; the DC electromagnet 34 is connected to the electromagnet mounting seat 32 by screws, and the guide column 322 of the electromagnet mounting seat 32 is in the guide sleeve 314 of the brake frame 31 and can slide with each other; the electromagnet mounting seat 32 is provided with a threaded hole, and the brake frame 31 is provided with a through hole for the brake shaft 33. The end of the brake shaft 33 is threaded and connected to the threaded hole on the electromagnet mounting seat 32 through the through hole of the brake frame 31; the spring 35 passes through the brake shaft 33 and is installed between the brake frame 31 and the clamping nut 36.

[0074] like Figure 7 As shown, when working, due to a certain gap between the DC electromagnet 34 and the F rail 10, the DC electromagnet 34 cannot be actively adsorbed on the F rail 10, and the brake shaft 33 and the handle 37 need to be manually pushed to drive the electromagnet mounting seat 32 and the DC electromagnet 34 to approach and adsorb on the F rail 10. At this time, the clamping nut 36 installed on the shaft 33 compresses the spring 35. Since the guide column 322 is installed in the guide sleeve 314, the entire brake assembly cannot be displaced relative to each other when working, thereby playing a braking role; when not working, the DC electromagnet 34 is powered off, and the force of the compressed spring 35 acting on the clamping nut 36 drives the brake shaft 33, and then drives the electromagnet mounting seat 32 and the DC electromagnet 34 to separate from the F rail 10. At this time, the brake is in a non-working state.

[0075] 4. Handle assembly 4

[0076] like Fig.10 As shown, the handle assembly 4 is installed at the middle height position of the front side end plate 111 of the vehicle body, close to one side of the brake assembly 3. The handle assembly 4 includes a handle 41, a rotating shaft 42, a handle fixing seat 43, a gear 44, a bearing 45 and a bearing spacer 46.

[0077] 5. Lock pin assembly 5

[0078] like Fig.11 and Fig.12 As shown, the lock pin assembly 5 includes: two lock pin seats 51 and a lock pin 52 arranged opposite to each other, which are installed at the middle position of the height of the side plate 112 close to the end plate 111. The lock pin seat 51 is an annular structure, and the lock pin 52 is welded by a T-shaped round bar. The lock pin 52 is installed in the ring of the lock pin seat 51 to ensure that the lock pin 52 does not fall and can rotate around the lock pin seat 51. The lower end surface of the round bar part of the lock pin 52 is processed with a groove to prevent the handle 41 from slipping off the lock pin 52 when the lock pin assembly 5 is working.

[0079] 6. Spindle assembly 6

[0080] like Fig.12 and Fig.13As shown, the spindle assembly 6 includes: a mounting plate 61, a rack 62, a slider 63, a stopper 67 and a drill assembly. The drill assembly includes: an electric spindle 64, a tool holder 65 and a drill 66. The mounting plate 61 is "L" shaped, and its horizontal plate is provided with three holes for the output shaft of the electric spindle 64. The center distance of the holes is determined by the center distance of the hole group of the fixed aluminum induction plate 30. The slider 63 is installed on the back of the mounting plate 61 and is installed in conjunction with the linear guide 13. The rack 62 is installed on the back of the mounting plate 61 and close to the outside. It meshes with the gear 44 of the handle assembly 4 for transmission. Shaking the handle 41 causes the gear 44 to rotate, which is transmitted through the slider 63, so that the spindle assembly 6 as a whole is transmitted up and down along the linear guide 13.

[0081] The working principle of the present invention is:

[0082] The F-rail drilling vehicle is placed on the F-rail 10 on which the aluminum induction plate 30 has been laid. The worker pushes the vehicle to the drilling position by hand using the handle 12, turns on the power supply of the DC electromagnet 34 on the brake assembly 3, and pushes the brake shaft 33 to make the DC electromagnet 34 contact with the inclined surface of the F-rail 10, so that the DC electromagnet 34 is adsorbed and fixed on the F-rail 10. At this time, the entire vehicle is in a fixed state.

[0083] The handle 41 of the handle assembly 4 is pressed downward, and the handle 41 is disengaged from the locking pin 52 of the locking pin assembly 5 , and the locking pin 52 is moved so that the locking pin 52 is against the side of the box-type frame 11 .

[0084] The power supply of the electric spindle 64 on the spindle assembly 6 is turned on, and the handle 41 is rotated to lower the spindle assembly 6, and when the drill bit 66 contacts the aluminum induction plate 30, a hole is drilled downward.

[0085] After the drilling is completed, the handle 41 is rotated in the opposite direction to lift the spindle assembly 6. When the drill bit 66 is separated from the aluminum induction plate 30 to a certain height, the lock pin 52 is moved to fix the handle 41 on the lock pin 52; the power supply of the electric spindle 64 and the DC electromagnet 34 is turned off, and the handle 37 is manually pulled outward to separate the DC electromagnet 34 from the F rail 10. At this time, the drilling vehicle is in an active state; the hand handle 12 pushes the device along the length direction of the F rail 10 to reach the next working point to continue drilling.

[0086] In summary, the present invention also has the following advantages:

[0087] (1) The drilling vehicle is designed with lifting lugs according to the center of gravity, which is convenient for lifting;

[0088] (2) When designing the drilling vehicle frame, thin plate welding is used while ensuring strength. The vehicle body compartment can be used to place counterweights, saving materials and making it easier to carry when not working;

[0089] (3) The wheels of the drilling vehicle have good stability and guidance, and are easy to move and save effort. The guide wheel set 21 can be made of nylon to avoid indentations on the aluminum induction plate 30 of the F rail 10, which would affect the quality of the F rail 10.

[0090] (4) A chip guard plate 7 is installed at the bottom of the drilling vehicle to prevent iron chips from entering the bottom of the vehicle body and causing the nylon wheel to roll over and damage the wheel and scratch the aluminum induction plate 30 during rolling;

[0091] (5) In addition to placing counterweights, the vehicle compartment can also be used to place tools used during operations, and has a storage function.
