Description

Technical Field

[0001] This utility model relates to the field of track maintenance technology, specifically a simple column-type inspection pit track fine-tuning device. Background Technology

[0002] A column-type inspection pit is an infrastructure used in rail transit systems such as railways and subways to inspect the underside of vehicles and bogies. Also known as a column-type maintenance pit or trench inspection pit, it typically consists of concrete or steel columns installed within the pit, with rails laid on top of the columns. The track's level, gauge, and elevation parameters must be maintained with high precision to ensure safe train operation. Therefore, the track requires regular inspection and fine-tuning based on the inspection results.

[0003] Traditional fine-tuning methods typically utilize a track inspection trolley equipped with sensors or a total station. As the trolley travels along the track, parameters of the entire track are obtained. However, current track trolleys have their push rods, computer brackets, and testing equipment mounted on top, while the depth of the column-type inspection pit is generally 1.2-1.5 meters. This makes the trolley taller than a person's head, inconvenient to push and use. Existing technology allows the push rod to rotate to a horizontal position to reduce its height and facilitate use, but the push rod is still higher than a person's elbow. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a simple column-type inspection pit track fine adjustment device.

[0005] The technical solution of this utility model is:

[0006] A simple fine-tuning device for a column-type inspection pit track, comprising:

[0007] The inspection vehicle consists of a main support and a sliding support, and moves along a track via wheels. The main support is used to install testing instruments, and a push rod is rotatably installed in the middle of the top surface of the main support. A computer bracket is provided on the front side of the head of the push rod.

[0008] The push rod includes a rotating rod and a T-shaped rod. The T-shaped rod is slidably connected to the rotating rod, and the upper half of the vertical rod of the T-shaped rod is bent at 40-60° toward the rear side of the main support.

[0009] The computer stand includes a computer tray, which is mounted on the front side of the crossbar of the T-shaped rod via a rotating structure. The rotating structure is used to adjust the angle of the computer tray.

[0010] Preferably, one end of the sliding bracket is inserted into the main bracket and slidably connected to the main bracket, and the main bracket is provided with a telescopic rod inside, which is used to drive the sliding bracket to move horizontally.

[0011] Preferably, the bottom surfaces of the main support and the sliding support are provided with limiting wheels via side-mounted brackets, the wheel surfaces of the limiting wheels abut against the inner surfaces of the rails, and a pressure sensor is provided between the limiting wheels and the side-mounted brackets.

[0012] Preferably, the bottom end of the rotating rod is rotatably connected to the main support through a semi-circular adjusting plate. The adjusting plate has several circular through holes evenly distributed on its edge, and the bottom of the rotating rod is engaged with the through holes of the adjusting plate through a fixing pin.

[0013] Preferably, the rotating rod port is provided with a first quick-release clamp. When the first quick-release clamp is closed, it restricts the sliding of the T-shaped rod. When the first quick-release clamp is open, the T-shaped rod can slide freely to achieve length adjustment.

[0014] Preferably, when the rotating rod is rotated backward to a horizontal state, the crossbar portion of the T-shaped rod is parallel to the bottom surface of the maintenance pit, and the distance from the crossbar portion of the T-shaped rod to the bottom surface of the maintenance pit is 0.9-1.1m.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0029] A simple fine-tuning device for a column-type inspection pit track, comprising:

[0030] Inspection vehicle 1 consists of a main support 11 and a sliding support 12. It moves along the track via casters 14. The main support 11 is used to install testing instruments. A push rod 2 is rotatably installed in the middle of the top surface of the main support 11. A computer bracket 3 is provided on the front side of the head of the push rod 2.

[0031] Push rod 2 is used to push inspection cart 1 to move along the track, computer bracket 3 is used to place computer, computer is used to display inspection data.

[0032] The main support 11 is T-shaped, with the short rod parallel to the track and the long rod perpendicular to the track. The moving wheels 14 are metal rollers, located at the front and rear ends of the T-shaped short rod below the main support 11. The wheel width of the moving wheels 14 needs to be greater than the track width.

[0033] The movable wheel 14 below the sliding bracket 12 is located below the end.

[0034] The top of the short rod of the main bracket 11 is a recessed groove, which can be used to install a battery that powers the device.

[0035] Testing instruments include, but are not limited to, prisms, total stations, levels, and calipers.

[0036] One end of the sliding bracket 12 is inserted into the main bracket 11 and slidably connected to the main bracket 11. The main bracket 11 is provided with a telescopic rod 13, which is used to drive the sliding bracket 12 to move horizontally.

[0037] The telescopic rod 13 can be a servo electric actuator, which can precisely control the moving length of the actuator. By operating the telescopic rod 13, it can be driven to move horizontally, and the moving distance can be controlled.

[0038] The bottom surfaces of the main support 11 and the sliding support 12 are provided with a limiting wheel 16 via a side-mounted support 15. The inner surfaces of the wheel surfaces of the limiting wheel 16 abut against the rail. A pressure sensor 17 is provided between the limiting wheel 16 and the side-mounted support 15.

[0039] The limit wheel 16 is used to prevent the inspection vehicle 1 from derailing.

[0040] Pressure sensor 17 is used to detect the pressure on limit wheel 16. When the track gauge changes, the pressure on limit wheel 16 will change.

[0041] The sliding bracket 12 moves by the working drive of the telescopic rod 13, and the pressure of the limit wheel 16 is adjusted back to the predetermined value. The adjustment distance of the telescopic rod 13 is the deviation value of the track gauge.

[0042] The push rod 2 includes a rotating rod 21 and a T-shaped rod 22. The T-shaped rod 22 is slidably connected to the rotating rod 21. The upper half of the vertical rod of the T-shaped rod 22 is bent at 40-60° toward the rear side of the main support 11.

[0043] In this embodiment, the bending angle of the T-shaped rod 22 is 45°. When the upper part of the T-shaped rod 22 is parallel to the horizontal plane, the rotating rod 21 forms a 45° angle with the top surface of the main support 11, which facilitates the maintenance of ordinary bottom track.

[0044] The bottom end of the rotating rod 21 is rotatably connected to the main support 11 through a semi-circular adjusting plate 24. The edge of the adjusting plate 24 is evenly provided with several circular through holes, and the bottom of the rotating rod 21 is engaged with the through holes of the adjusting plate 24 through a fixing pin 25.

[0045] After the fixing pin 25 is inserted into the adjusting plate 24, it can restrict the rotation of the rotating rod 21.

[0046] There are 12 through holes, and the angle between the line connecting two adjacent through holes and the center of the adjustment plate 24 is 15°.

[0047] The angle of the rotating rod 21 can be adjusted by inserting the retaining pin 25 into different through holes.

[0048] The rotating rod 21 is equipped with a first quick-release pipe clamp 23. When the first quick-release pipe clamp 23 is closed, it restricts the sliding of the T-shaped rod 22. When the first quick-release pipe clamp 23 is open, the T-shaped rod 22 can slide freely to achieve length adjustment.

[0049] The first quick-release pipe clamp 23 uses an eccentric handle. By rotating the handle, the inner diameter of the pipe opening of the rotating rod 21 can be adjusted, thereby fixing the T-shaped rod 22.

[0050] When the rotating rod 21 is rotated backward to a horizontal position, the horizontal part of the T-shaped rod 22 is parallel to the bottom surface of the maintenance pit. At this time, the distance from the horizontal part of the T-shaped rod 22 to the bottom surface of the maintenance pit is 0.9-1.1m.

[0051] The crossbar of the T-bar 22 is designed for operator gripping, with a height of 0.9-1.1m, allowing most people to keep their forearms and elbows horizontal when gripping it, thus improving comfort.

[0052] In this embodiment, a height of 1m is used.

[0053] The computer stand 3 includes a computer tray 35, which is mounted on the front side of the crossbar of the T-shaped rod 22 via a rotating structure. The rotating structure is used to adjust the angle of the computer tray 35.

[0054] The rotating structure includes two sliding sleeves 31, which are slidably connected to the crossbar of the T-shaped rod 22. A locking screw 32 is radially threaded in the middle of the sliding sleeve 31. When the locking screw 32 is tightened, it presses against the crossbar of the T-shaped rod 22, which can restrict the movement and rotation of the sliding sleeve 31.

[0055] A clamping plate 33 is welded to the side of the sliding sleeve 31 and to the opposite side of the locking screw 32. A connecting plate 34 is fixedly installed on the clamping plates 33 of the two sliding sleeves 31 by screws. The head of the connecting plate 34 is bent at 30° toward the vertical part of the T-shaped rod 22. The head of the connecting plate 34 is fixedly connected to the computer tray 35 by screws.

[0056] By loosening the locking screw 32, the sliding sleeve 31 can be rotated, thereby adjusting the angle of the computer tray 35.

[0057] The 35mm computer tray is used for attaching a computer card. Depending on usage habits, a tray adapted for tablets or laptops can be replaced.

[0058] Working principle:

[0059] Place the inspection vehicle 1 on the track, ensuring that the moving wheel 14 is on the top surface of the track.

[0060] The telescopic rod 13 is controlled to work, driving the sliding bracket 12 to extend, so that the limit wheel 16 abuts against the side of the track and the pressure sensor 17 reaches the set value.

[0061] Remove the retaining pin 25, rotate the rotating rod 21 to a horizontal position, and then insert the retaining pin 25 to complete the fixing.

[0062] At this time, the crossbar of T-shaped rod 22 is lower than the main support 11.

[0063] Then loosen the locking screw 32 and adjust the computer tray angle 35. The angle can be adjusted according to individual usage. When holding the crossbar of the T-shaped bar 22, you can observe it by slightly lowering your head.

[0064] The testing equipment is installed on the top surface of the inspection vehicle 1. The inspection vehicle 1 is moved by the push rod 2. When the track gauge changes, the pressure of the limit wheel 16 will change. The sliding bracket 12 is moved by the operation of the telescopic rod 13, adjusting the pressure of the limit wheel 16 back to the predetermined value. The adjustment distance of the telescopic rod 13 is the deviation value of the track gauge.

[0065] Opening the first quick-release tube clamp 23 allows adjustment of the length of the T-shaped rod 22.
