[0002] The tunnel cable trench and arch grouting trolley is a multi-functional piece of equipment used in tunnel construction. It is mainly used to simultaneously complete cable trench and arch grouting operations, integrating the two operations into one machine. This reduces equipment investment and construction site occupation, avoids frequent scheduling and switching between different machines, greatly improves construction efficiency, and shortens the construction period. It can operate according to design requirements and construction specifications, ensuring the dimensional accuracy of the cable trench and the fullness and uniformity of the arch grouting, thereby improving construction quality.

[0003] The existing trolleys for cable trenches and arch grouting in tunnels are usually positioned manually. Manual positioning can lead to certain deviations, and the trolley cannot make fine adjustments during positioning, resulting in insufficient precision. This can cause deviations during docking, leading to problems such as insufficient grouting or leakage during grouting.

[0004] Therefore, those skilled in the art have provided a trolley for both cable trench and arch grouting in tunnels to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shared trolley for cable trenches and arch grouting in tunnels, which allows for fine adjustments to the trolley's position and improves the accuracy of the adjustments.

[0024] 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.

[0025] Reference Figure 1 , Figure 2 One embodiment provided by this utility model:

[0026] A trolley for cable trench and arch grouting in tunnels includes a base plate 2, a fine-adjustment mechanism 3 fixedly installed at the top of the base plate 2, a connecting plate 4 fixedly installed at the top of the fine-adjustment mechanism 3, a fixing mechanism 9 fixedly installed on one side of the connecting plate 4, a vehicle body 1 fixedly installed at the bottom of the base plate 2, a control rod 7 fixedly installed on one side of the base plate 2, an electrical control cabinet 5 fixedly installed on one side of the top of the connecting plate 4, a mixing tank 6 fixedly installed in front of the bottom of the connecting plate 4, a high-pressure grouting machine 8 fixedly installed behind the top of the connecting plate 4, and multiple grooves 10 evenly opened on one side of the top of the base plate 2.

[0027] Specifically, the base plate 2 is fixed on the vehicle body 1, the fine-tuning mechanism 3 is used to drive 4 to move, the connecting plate 4 is used to fix the electrical control cabinet 5, the mixing tank 6 and the high-pressure grouting machine 8. The mixing tank 6 is used to add materials such as cement, water and additives in a certain proportion into the mixing tank 6, and the mixing system mixes them to make slurry. The high-pressure grouting machine 8 is used to extract the slurry in the mixing tank 6 and inject it into the grouting hole. The groove 10 is used to assist the fixing mechanism 9 in fixing, and the control rod 7 is used to facilitate the movement of the trolley.

[0028] Reference Figure 3The fine-tuning mechanism 3 includes two first fixed plates 302 and a support frame 304. The top of the two first fixed plates 302 is provided with a moving groove 301. The top of the support frame 304 is fixedly provided with a servo motor 305. The output end of the servo motor 305 is fixedly connected to a connecting rod 303. Multiple connecting blocks 307 are slidably connected to both sides of the two first fixed plates 302. The multiple connecting blocks 307 are rotatably connected to rollers 306. The connecting rod 303 passes through and connects to one side of the roller 306. One end of the connecting rod 303 is fixedly connected to one side of the roller 306.

[0029] Specifically, the servo motor 304 is started, which drives the connecting rod 303 to rotate. While the rotating rod 303 is rotating, it drives the rollers 306 on both sides to rotate. While one side of the roller is rotating, it drives the connecting block 307 on the surface to move. Since the connecting plate 4 is fixed at the top of the connecting block 307, when one side of the connecting block 307 moves, it drives the moving block 307 on the other side to move together. The support frame 304 is used to fix and support the servo motor 304, and the moving groove 301 is used to facilitate the movement of the connecting block 307 when the roller 306 rotates.

[0030] Reference Figure 4 The fixing mechanism 9 includes a first fixing block 901, a fixing rod 904 rotatably connected inside the first fixing block 901, a second fixing plate 905 fixedly installed on one side of the bottom end of the first fixing block 901, a second fixing block 902 fixedly installed on one side of the bottom end of the first fixing block 901, a pin 906 slidably connected inside the second fixing plate 905, and a spring 903 fixedly installed on the surface of the pin 906;

[0031] Specifically, pull out the pin 906 and rotate it to rest on the second fixing block 902. Then adjust its position. The fixing rod 904 can freely move in and out of the groove 10 during the adjustment. When the position is adjusted, the fixing rod 904 falls into the corresponding groove 10. Then rotate the pin 906 again. The pin 906 is subjected to the elastic force of the spring 903 and will automatically fall into the hole on one side of the fixing rod 904 to fix the fixing rod 904. At this time, the fixing rod 904 will no longer be able to move.

[0032] Working principle: When the trolley reaches the position, pull the pin 906 to pull the pin 906 out of the hole on one side of the fixing rod 904. Then rotate the pin 906 so that one end of the pin 906 rests on the second fixing block 902 to prevent the pin 906 from automatically falling into the hole on one side of the fixing rod 904. Then, start the servo motor 305. The servo motor 305 drives the connecting rod 303 to rotate, which in turn drives the roller 306 on the same side to rotate. When the roller 306 on one side rotates, since the connecting plate 4 is connected to the top of multiple connecting blocks 307, when the roller 306 on one side drives the connecting block to move, it will drive the other rollers 306 to move together, thus achieving the effect of moving together.

[0033] Secondly, as the connecting plate 4 moves, since one end of the pin 906 rests on the second fixing block 902, the fixing rod 904 will continuously insert into and move out of the groove 10 in the direction of the connecting plate 4's movement, and will not be fixed in any particular groove 10 until the trolley moves to the precise position. At this point, the fixing rod 904 will stop in the corresponding groove 10. Then, the pin 906 will be rotated, and the pin 906 will lose the obstruction of the second fixing block 902. Under the elastic force of the spring 903, the pin 906 will automatically insert into the hole on one side of the fixing rod 904 to form a fixation, preventing the connecting plate 4 from moving further. This achieves the fixation of the required position, improves the accuracy of the trolley, and ultimately reduces problems such as insufficient grouting or grout leakage caused by positional deviation.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
