Description

Technical Field

[0001] This utility model relates to the technical field of track frames for tunneling machines, specifically a track frame for tunneling machines. Background Technology

[0002] A tunneling machine is a combined unit that can simultaneously complete coal and rock breaking, loading and transfer, transportation and dust suppression spraying. It has the advantages of fast tunneling speed and stable tunneling roadway, and is widely used in various tunneling operations. When the tunneling machine moves, it needs to use the track frame to support the track for utilization. Therefore, a track frame for tunneling machines is provided.

[0003] For example, a track frame for a tunneling machine with announcement number "CN216684655U" uses a positioning sleeve to position the cylinder extension shaft, thereby preventing the extension shaft from shifting, avoiding damage to the cylinder, improving the working stability of the track frame, and extending its service life. However, the above-mentioned model lacks a track protection structure. Since the tracks are in direct contact with the ground during the tunneling machine's movement, they are prone to collisions with rocks or debris in complex environments, leading to damage to the tracks and reducing their service life. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of track protection structure, which is not provided for tunneling machines. During the movement of the tunneling machine, the track is in direct contact with the ground and is easily impacted by rocks or debris in complex environments, which will cause damage to the track and reduce its service life. Therefore, a track frame for tunneling machines is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a track frame for a tunneling machine, including a frame body and crossbeams. The upper end of the outer wall of the frame body is fixedly connected to the crossbeams. Through holes are machined on both sides of the two crossbeams. Track protection structures are provided on both sides of the frame body. Multiple track wheels are installed on both sides of the frame body. Multiple track auxiliary wheels are installed in the middle of the frame body.

[0007] Preferably, the track protection structure includes an outer shell, a rubber pad is fixedly connected to the rear side of the outer wall of the outer shell, a plurality of ear plates are fixedly connected to the upper end of the outer wall of the outer shell, the inner walls of the plurality of ear plates are threadedly connected to bolts, and a plate is fixedly connected to the inner wall of the outer shell by a bracket.

[0008] Preferably, the end of the bolt is threaded to the frame.

[0009] Preferably, the outer wall of the rubber pad abuts against the frame.

[0010] Preferably, the outer walls of the plurality of track wheels and track auxiliary wheels are engaged with the track.

[0011] The present invention provides a track frame for a tunneling machine, which has the following advantages: Through the track protection structure, the outer shell is removed, and the internal threaded holes of multiple ear plates are aligned with the threaded holes on the outer wall of the frame. Then, multiple bolts are removed and sequentially inserted into the ear plates and the frame. During this process, the traction of the bolts causes the rubber pads to abut against the outer wall of the frame. The rubber pads ensure a tight connection between the outer shell and the frame, thereby improving stability. Simultaneously, the plates on the inner wall of the outer shell provide support. The outer shell is then installed on the frame using bolts, and finally, the outer shell covers the track. This reduces the probability of damage to the track from direct impacts by rocks and debris during tunneling machine operation, thus extending the track's service life. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5 In this embodiment, a track frame for a tunneling machine includes a frame body 2 and a cross frame 3. The upper end of the outer wall of the frame body 2 is fixedly connected to the cross frame 3. Through holes 4 are machined on both sides of the two cross frames 3. The frame body can be installed on an external tunneling machine by using external bolts through the through holes 4. Track protection structures 1 are provided on both sides of the frame body 2. Multiple track wheels 5 are installed on both sides of the frame body 2.

[0020] Multiple track auxiliary wheels 7 are installed in the middle of the frame 2. The ends of bolts 103 are threaded to the frame 2. The rotatable bolts 103 can install the outer shell 101 on the outer wall of the frame 2. The outer wall of the rubber pad 105 is pressed against the frame 2. The rubber pad 105 can ensure the tightness of the connection between the outer shell 101 and the frame 2. The outer walls of the multiple track wheels 5 and track auxiliary wheels 7 are engaged with the track 6.

[0021] See attached document Figure 1-5 Track protection structure 1 includes an outer shell 101, a rubber pad 105 is fixedly connected to the rear side of the outer wall of the outer shell 101, a plurality of ear plates 102 are fixedly connected to the upper end of the outer wall of the outer shell 101, the inner walls of the plurality of ear plates 102 are threadedly connected to bolts 103, and a plate 104 is fixedly connected to the inner wall of the outer shell 101 through a bracket.

[0022] The plate 104 can support the outer shell 101, effectively improving the protective strength of the outer shell 104. By rotating the bolt 103, the outer shell 101 can be installed on the frame 2, thereby protecting the track 6 through the outer shell 104 and effectively reducing the probability of damage caused by direct collision between rocks and the track 6.

[0023] Working principle:

[0024] Installation of track frame for tunneling machine:

[0025] When it is necessary to install protection on the track frame, remove the outer shell 101 and align the internal threaded holes of the multiple ear plates 102 with the threaded holes on the outer wall of the frame 2. Then, remove the multiple bolts 103 and screw them into the ear plates 102 and the frame 2 in sequence. During this process, the traction of the multiple bolts 103 will cause the outer shell 101 to abut against the outer wall of the frame 2. The rubber pad 105 can ensure the tightness of the connection between the outer shell 101 and the frame 2, thereby improving stability. This movement can be used to install the outer shell 101. At the same time, the plate 104 set on the inner wall of the outer shell 101 can support the outer shell 101 and effectively improve the protective strength of the outer shell 101. By covering the track 6 with the outer shell 101, the probability of rocks and debris directly impacting the track 6 during the operation of the tunneling machine can be reduced, thereby increasing the service life of the track 6. Then, the two crossbars 3 can be installed on the external tunneling machine using the pre-set through holes 4 at both ends and the external bolts.
