[0014] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0015] Example 1

[0016] like Figure 1-4 As shown, the track structure used for the installation of the double-blade mining cutter adopts a splicing structure of multiple short tracks 302. The two adjacent short tracks 302 are connected by auxiliary support sleeves 303. The auxiliary support sleeves 303 are provided with a through groove 304 with an upper opening. The through groove 304 is consistent with the structure of the track bottom 305. Raised pressing plates 306 are provided on both sides of the bottom of the auxiliary support sleeves 303. Auxiliary support sleeves 303 are also sleeved near the middle of the short track 302, which can achieve multiple supports and better support stability. The auxiliary support sleeve 303 in the middle where the short track 302 is connected is fixed to the ground, and the auxiliary support sleeves 303 between the middle and the two ends do not need to be fixed to the ground and the short track 302, and only need to be leveled and stressed. Each auxiliary support sleeve 303 is locked on the surface of the foundation pit by a pressing plate 306 and an expansion screw 307.

[0017] Furthermore, a transition track group 308 is installed between two adjacent groups of tracks 301. The transition track group 308 can be obliquely spliced ​​to the adjacent groups of tracks 301 near the ends. The tracks of the transition track group 308 are connected to the tracks 301 of the main line by a detachable elbow sleeve 309. Two sections of connected track heads 310 are arranged at the corners of the elbow sleeve 309, which can quickly connect the two straight short tracks 302 to achieve a smooth transition without the need for additional processing.

[0018] A plurality of auxiliary support sleeves 303 are installed on the transition track group 309. The bottom surface of the auxiliary support sleeves 303 is provided with hard rubber shock-absorbing pads 311. The hard rubber shock-absorbing pads 311 can play a shock-absorbing role while providing a certain rigid support.

[0019] The auxiliary support sleeve 303 is used to splice and auxiliary support the track 301, which can greatly improve the track installation efficiency. The auxiliary support sleeve 303 is fixed by the pressing plate 306, and the pressing space is wide, which is convenient for locking the track 301. After the auxiliary support is inserted into the track 301, the side surface is locked with a locking screw, and the installation is quick and convenient; the transition track group 308 and the elbow sleeve 309 are arranged, and the double-blade mining cutter can be quickly moved to the adjacent track group, which can prevent the lifting equipment from being affected by the beam above the foundation pit or the lifting position being limited; the detachable structure is easy to assemble and disassemble, and can be reused to improve the equipment utilization rate; the hard rubber shock-absorbing pad 311 is set to improve the shock-absorbing effect of the track, and prevent the vibration of the cutting motor from being transmitted to the ground through the track and then interfering with the cutting tool, affecting the tool cutting.

[0020] Track laying: Track laying is carried out on the foundation pit soil surface; the specific method and steps are as follows:

[0021] 1.1 After the base surface is cleaned, the ground is relatively flat. When laying the track, first clean the loose slag on the surface of the track support and reinforcement to ensure that the foundation of the track support is firm and reliable and the ground is relatively flat.

[0022] 1.2 The track adopts a 4-meter standard track, that is, a short track. Each section of the track is fixedly connected with an auxiliary support sleeve and bolts or a connecting plate with bolts. The level meter is used to level the two track surfaces so that they are parallel to the same horizontal plane. The two tracks must be parallel and the two track surfaces should be on the same level. The error should be less than 1 / 1000;

[0023] 1.3 According to the cutting depth of each layer, first install the first track, and then reinforce it after checking the straightness and flatness of the cutting edge. Based on the first track, use a level ruler and caliper to install the second steel track with a spacing of 2.6mm. The width of each track should be consistent and the installation should be horizontal, firm and reliable.

[0024] 1.4 When the track is laid directly on the ground, two adjacent short tracks are butt-jointed and fixedly connected to the ground with auxiliary support sleeves, or laid using the following methods: use guide holes to drive steel fibers to fix and clamp them to the bedrock; when the rock surface is relatively flat and the track is less than 100mm from the ground, use holes drilled on both sides of the track to insert steel pins for fixation; when the distance from the rock surface is greater than 100mm and less than 200mm, use holes drilled in the rock between the two tracks to insert steel pins and use two φ22 round steels to cross weld and fix them, and use sleepers and wooden wedges for leveling; for bedrock with a height difference greater than 200mm, rock square materials can be used for padding or jacks can be used for automatic fine-tuning;

[0025] 1.5 After the track installation is completed, the verticality and horizontality of the track should be checked again. A laser level is installed at the end of the track to automatically level and straighten the track. Multiple cutting tracks can be installed at one time. Each set of tracks is reserved for the cutting start end to install the transition track. The transition track is used to splice adjacent track groups and transfer the double-blade mining cutting machine to perform continuous cutting on the same track line.

[0026] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
