Description

Technical Field

[0001] This utility model belongs to the technical field of railway construction equipment, and in particular relates to a special frame for a track drilling machine. Background Technology

[0002] Currently, when the roadbed of a railway track softens and its bearing capacity is insufficient, the softened roadbed needs to be treated by roadbed replacement. The specific treatment method is to use a drilling machine to drill holes at multiple points on both sides of the railway track along the softened roadbed, and then fill the holes with lime and soil for treatment.

[0003] Because drilling requires multiple drilling points, the drilling machine needs to be moved multiple times along the railway track in the front-back and left-right directions. After each movement, the drilling machine needs to be fixed in place to prevent the hole from deviating. However, the existing frame used to support the drilling machine is not convenient for moving the machine along the railway track in the front-back and left-right directions, nor is it convenient for fixing the machine in place. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a special frame for a track drilling machine to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A special frame for a track drilling machine includes a horizontally arranged rectangular base. Track wheel assemblies with a traveling direction parallel to the width direction of the rectangular base are installed at the four corners of the bottom surface of the rectangular base. A movable frame is slidably connected to the top surface of the rectangular base. The moving direction of the movable frame is parallel to the length direction of the rectangular base, and a vertically distributed support frame is installed on one side of the movable frame.

[0007] Both sides of the rectangular base frame are equipped with a first locking mechanism. Each first locking mechanism includes a fixing plate opposite to the position of the track wheel assembly. The fixing plate is horizontally installed on the rectangular base frame, and both sides of the fixing plate are suspended and have notches. A first locking plate is provided below the fixing plate. The first locking plate is parallel to the length direction of the rectangular base frame, and both ends of the first locking plate are hinged with locking rods. The rods of the locking rods are located in the notches, and the ends of the locking rods away from the first locking plate are threaded with a first locking nut. The movable frame and the rectangular base frame are connected by friction sliding connection.

[0008] Furthermore, the rectangular base frame includes two horizontally opposite long side beams, both of which are U-shaped beams with outward openings, and several short side beams are fixedly connected between the two long side beams. The movable frame is a horizontally distributed rectangular frame, with the bottom surface of the movable frame in contact with the top surface of the rectangular base frame. Vertically distributed limiting plates located outside the long side beams are installed at the four corners of the movable frame, and the bottom of each limiting plate is bent inwards and located inside the long side beams.

[0009] Furthermore, a second locking mechanism is provided between the two side frames of the movable frame and the long side beam. The second locking mechanism includes a U-shaped rod, and a second locking plate is slidably sleeved between the two ends of the U-shaped rod. The ends of the U-shaped rod located outside the second locking plate are threaded with a second locking nut.

[0010] Furthermore, pads are installed at all four corners of the bottom surface of the movable frame.

[0011] Furthermore, two sets of the first locking mechanism are installed on both sides of the rectangular base frame.

[0012] Furthermore, each of the track wheel assemblies includes an inverted U-shaped bracket, which is mounted on the bottom surface of the rectangular base frame. A track wheel is rotatably connected inside the inverted U-shaped bracket. The axial line of the track wheel is parallel to the length direction of the rectangular base frame, and each track wheel is fitted with a limiting disc to prevent it from derailing.

[0013] Furthermore, a pull rod is installed on the movable frame.

[0014] Furthermore, inclined support rods are installed between the support frame and the movable frame.

[0015] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0016] Before use, this invention allows for the removal of stones and other debris from the roadbed and surface that support the railway tracks, suspending the tracks between the sleepers. A support frame is installed on the movable frame, allowing the drilling machine to be vertically mounted on the side of the support frame away from the movable frame. A lifting mechanism capable of raising and lowering the drilling machine can be installed on the support frame. During use, track wheel assemblies with a travel direction parallel to the width of the rectangular base frame are installed at each of the four corners of the base, facilitating movement of the rectangular base frame along the two railway tracks. Furthermore, since the movable frame and the rectangular base frame are slidably connected, and the movement direction of the movable frame is parallel to that of the rectangular base frame... The rectangular base frame is parallel to the horizontal axis of the rectangular base frame, allowing the movable frame to move along its length under external force. This facilitates the movement of the drilling machine along the railway track in both forward and backward, as well as left and right. Secondly, the first locking mechanism secures the rectangular base frame to the railway track. Furthermore, the frictional sliding connection between the movable frame and the rectangular base frame allows for easy fixation of the movable frame to the rectangular base frame once it is in place, further enhancing the ability to maintain the drilling machine's position for multi-point drilling operations on softened roadbeds.

[0024] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, this utility model provides a special frame for a track drilling machine, including a horizontally arranged rectangular base frame 4. Track wheel assemblies 5 are installed at the four corners of the bottom surface of the rectangular base frame 4, with the traveling direction parallel to the width direction of the rectangular base frame 4. In use, the track wheel assemblies 5 facilitate the movement of the rectangular base frame 4 along two railway tracks. When the rectangular base frame 4 is installed on the railway tracks, both ends of the rectangular base frame 4 are located outside the two railway tracks. A movable frame 1 is slidably connected to the top surface of the rectangular base frame 4. The moving direction of the movable frame 1 is parallel to the length direction of the rectangular base frame 4. Thus, under the action of external force, the movable frame 1 can move along the length of the rectangular base frame 4. The moving frame 1 is positioned along the length of the rectangular base frame 4 and is equipped with a vertically distributed support frame 6. Specifically, the support frame 6 is located on one side of the moving frame 1, near the length of the rectangular base frame 4. In use, the punch can be vertically mounted on the support frame 6 on the side away from the moving frame 1, and a lifting mechanism capable of raising and lowering the punch can be installed on the support frame 6. Since the rectangular base frame 4 can be easily moved along two railway tracks, and the moving frame 1 can be easily moved along the length of the rectangular base frame 4, the position of the punch can be easily moved along the railway tracks in the front-back and left-right directions during use.

[0026] Secondly, a first locking mechanism 2 is installed on both sides of the rectangular base frame 4. The first locking mechanism 2 includes a fixing plate 21 opposite to the position of the track wheel assembly 5. The fixing plate 21 is horizontally installed on the rectangular base frame 4. In use, the fixing plate 21 is located above the railway track. The two sides of the fixing plate 21 are suspended and have notches 22. A first locking plate 23 is provided below the fixing plate 21. The first locking plate 23 is parallel to the length direction of the rectangular base frame 4. Locking rods 24 are hinged to both ends of the first locking plate 23. The rods of the locking rods 24 are located in the notches 22. The end of the locking rod 24 away from the first locking plate 23 is threaded with a first locking nut.

[0027] Specifically, before use, debris such as stones used to support the railway track can be cleared from the roadbed and road surface, suspending the railway track between the sleepers. Then, when it is necessary to fix the position of the rectangular base frame 4 on the railway track, by rotating the locking rod 24, the locking rod 24 can be made parallel to the first locking plate 23. Then, the locking rod 24 and the first locking plate 23 can be passed under the suspended railway track until the two locking rods 24 on the first locking plate 23 are respectively located on both sides of the railway track. Then, by rotating the locking rod 24, the rod body of the locking rod 24 is respectively located in the notch 22. Then, the locking rod 24 is divided into... Do not install the first locking nut. When the first locking nut is pressed against the fixed plate 21 and the first locking plate 23 is pressed against the railway track, the position of the rectangular base frame 4 can be fixed on the railway track. That is, the position of the rectangular base frame 4 can be easily fixed on the railway track through the first locking mechanism 2. In addition, the movable frame 1 and the rectangular base frame 4 are connected by friction sliding. When the movable frame 1 moves to the position, the position of the movable frame 1 can be easily fixed on the rectangular base frame 4 under the action of friction. Thus, when in use, it is easy to fix the position of the drilling machine so as to carry out multi-point drilling operations on the softened roadbed.

[0028] The specific arrangement of the friction sliding connection between the movable frame 1 and the rectangular base frame 4 is as follows: Figure 1 , Figure 2 , Figures 4 to 6 As shown, the rectangular base frame 4 includes two horizontally opposite long side beams 41, both of which are U-shaped beams with their openings facing outwards. Several short side beams 42 are fixedly connected between the two long side beams 41. The movable frame 1 is a horizontally distributed rectangular frame. The bottom surface of the movable frame 1 is in contact with the top surface of the rectangular base frame 4. Vertically distributed limiting plates 7 are installed at the four corners of the movable frame 1 and are located outside the long side beams 41. The bottom of the limiting plates 7 is bent inwards and located inside the long side beams 41, that is, the limiting plates 7 are vertically distributed L-shaped plates. In this way, during the movement of the movable frame 1, the limiting plates 7 can limit the range of movement of the movable frame 1 along the width direction of the rectangular base frame 4, and can limit the range of upward jumping of the movable frame 1. Secondly, since the long side beams 41 are U-shaped beams, it is convenient to assemble and disassemble the movable frame 1 on the rectangular base frame 4.

[0029] When fixing the position of the movable frame 1 on the rectangular base frame 4, if only the friction between the movable frame 1 and the rectangular base frame 4 is relied upon, the vibration generated by the drilling machine during drilling operations may sometimes cause the movable frame 1 to move, such as jumping or moving along the rectangular base frame 4. Therefore, to further fix the position of the movable frame 1 on the rectangular base frame 4, therefore, as Figure 1 , Figure 2 , Figures 4 to 6As shown, a second locking mechanism 3 is installed between the two side frames of the movable frame 1 and the long side beam 41. Each second locking mechanism 3 includes a U-shaped rod 31, with a second locking plate 32 slidably fitted between the two U-shaped ends of the U-shaped rod 31. A second locking nut 33 is threadedly connected to the end of the U-shaped rod 31 outside the second locking plate 32. Specifically, in use... Figure 4 For example, a U-shaped rod 31 can be first fitted onto the frame of the movable frame 1 and the long side beam 41. Then, the second locking plate 32 and the second locking nut 33 are installed on the U-shaped rod 31 in sequence. The U-shaped rod 31 is then pressed against the long side beam 41. By sliding the second locking plate 32, the second locking plate 32 is pressed against the frame of the movable frame 1. Finally, by rotating the second locking nut 33, the U-shaped rod 31 is pressed against the long side beam 41 and the second locking plate 32 is pressed against the frame of the movable frame 1. The position of the movable frame 1 can then be further fixed on the rectangular base frame 4 to avoid affecting the drilling operation. When it is necessary to move the position of the movable frame 1, the second locking mechanism 3 can be removed.

[0030] Furthermore, such as Figures 4 to 6 As shown, pads 8 are installed at the four corners of the bottom surface of the movable frame 1. Specifically, the pads 8 can reduce the contact area between the movable frame 1 and the rectangular base frame 4, thereby reducing the friction between the movable frame 1 and the rectangular base frame 4, which makes it easier for the movable frame 1 to move along the length of the rectangular base frame 4.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, two sets of the first locking mechanisms 2 are installed on both sides of the rectangular base frame 4. Specifically, a short side beam 42 is installed between the two sets of track wheel assemblies 5 located on the same side of the rectangular base frame 4. When installing the two sets of first locking mechanisms 2 located on the same side of the rectangular base frame 4, one set of first locking mechanisms 2 can be installed on the short side beam 42 located between the two sets of track wheel assemblies 5, and the other set of first locking mechanisms 2 can be installed on the side of the rectangular base frame 4 away from the support frame 6. In this way, when the drilling machine is installed on the support frame 6, it can avoid affecting the movement of the movable frame 1 along the length direction of the rectangular base frame 4. In addition, by installing four sets of first locking mechanisms 2 on the rectangular base frame 4, the position of the rectangular base frame 4 on the railway track can be further fixed.

[0032] The specific setup method for track wheel assembly 5 is as follows: Figures 1 to 3 , Figure 5 and Figure 6 As shown, each track wheel assembly 5 includes an inverted U-shaped bracket 51, which is mounted on the bottom surface of the rectangular base 4. A track wheel 52 is rotatably connected inside the inverted U-shaped bracket 51. The axial line of the track wheel 52 is parallel to the length direction of the rectangular base 4, and each track wheel 52 is fitted with a limiting disc 53 to prevent it from derailing. Specifically, it can be described as follows... Figure 5As shown, the limiting discs 53 are all installed on the inner side of the track wheels 52. In this case, during use, the limiting discs 53 are all located on the inner side of the two railway tracks. Alternatively, the limiting discs 53 can be installed on the outer side of the track wheels 52. In this case, during use, the limiting discs 53 are all located on the outer side of the two railway tracks. Furthermore, the two limiting discs 53 located at the same end of the rectangular base frame 4 can be arranged diagonally. In this case, during use, the two limiting discs 53 located at the same end of the rectangular base frame 4 are located on the inner and outer sides of each railway track, respectively. By setting the limiting discs 53, the rectangular base frame 4 can be prevented from moving along its length, thereby preventing the track wheels 52 from derailing.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, a pull rod 9 is installed on the movable frame 1. The pull rod 9 can be set as a vertically distributed L-shaped rod. By setting the pull rod 9, the movable frame 1 can be moved along the length direction of the rectangular base frame 4 by pushing and pulling.

[0034] Furthermore, such as Figure 1 As shown, inclined support rods 10 are installed between the support frame 6 and the movable frame 1. The support rods 10 can improve the stability of the support frame 6 on the movable frame 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
