Description

Technical Field

[0001] The utility model relates to the technical field of tunnel continuous belt conveyors, in particular to a double-end tape releasing machine in a tunnel and a continuous belt conveyor vulcanizing tape releasing system. Background Art

[0002] The tape releasing machine is a key device in the slag discharging system of the continuous belt conveyor, which can improve the efficiency of tape vulcanization and tape releasing, and enhance the tunnel excavation efficiency. For the continuous belt conveyor arranged in the storage bin cave, the tape needs to be transported into the tunnel and then vulcanized and released in the cave. The traditional tape winding methods include three methods: single roll double-end, single roll single-end, and eye roll (no end). Restricted by problems such as the space in the cave, lifting weight, and transportation safety, it is impossible to directly transport a single roll of tape to the vulcanization position in the cave.

[0003] For in-cave vulcanization and tape releasing, the traditional operation method is to first unfold and lay the tape in layers on the flatbed truck outside the cave, transport the tape to the vulcanization position in the cave by the flatbed truck, then obliquely pull the tape from the flatbed truck to the vulcanization platform for vulcanization, and after vulcanization, slowly release the tape from the flatbed truck manually, and only single-end tape releasing is possible; such as a vulcanization platform with the publication number of CN 211891616 U. The above entire vulcanization and tape releasing process is inefficient, seriously affecting the excavation efficiency. At the same time, manual tape releasing has great potential safety hazards and is prone to safety accidents. Content of the Utility Model

[0008] Further preferably, the reduction motor is connected to the tape feeding rack through a motor bracket, and the reduction motor is in power transmission with the driving shaft through a gear pair or a chain sprocket pair or a pulley pair.

[0009] Further preferably, the tape reel I has a total of four heads. Two heads form a free docking head, and the other two heads are wound into the tape reel II.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] As Figure 1 、 2 shown in Embodiment 1, a double - outlet tape - releasing machine in a tunnel includes a tape - releasing machine frame 1. A driven shaft group 2 and a driving shaft group 3 are provided on the tape - releasing machine frame 1. A Tape Roll Ⅰ 8 is provided on the driven shaft group 2, and a Tape Roll Ⅱ 9 is provided on the driving shaft group 3. The tapes on Tape Roll Ⅰ 8 and Tape Roll Ⅱ 9 are wound into a double - outlet eye - shaped roll. One driven shaft group 2 and one driving shaft group 3 form a master - slave shaft group. In actual use, one or more master - slave shaft groups can be provided on the tape - releasing machine frame 1 to adapt to different working conditions. In this embodiment, one driven shaft group 2 and one driving shaft group 3 are taken as an example. During the tape - releasing process, the driven shaft group rotates passively and the driving shaft group rotates actively. The driven shaft group and the driving shaft group cooperate to quickly release the tapes of Tape Roll Ⅰ and Tape Roll Ⅱ of the double - outlet eye - shaped roll.

[0022] As an implementation manner, the driven shaft group 2 includes a driven shaft 201. Both ends of the driven shaft 201 are rotatably connected to the tape unwinding rack 1 through bearings; a limiting member I for restricting the axial movement of the tape reel I is provided on the driven shaft. When unwinding the tape, the tape reel I rotates around the driven shaft group, and the driven shaft serves as the rotation support member of the tape reel I. A limiting member I for restricting the axial movement of the tape reel I 8 is provided on the driven shaft 201; the limiting member I can be a pin shaft or the like to prevent unnecessary axial movement of the tape reel I 8 and ensure the accuracy of tape unwinding.

[0023] As an implementation manner, the driving shaft group 3 includes a driving shaft 301. Both ends of the driving shaft 301 are rotatably connected to the tape unwinding rack 1 through bearings. A limiting member II for restricting the axial movement of the tape reel II 9 is provided on the driving shaft 301; the limiting member II can be a pin shaft or the like to prevent unnecessary axial movement of the tape reel II 9 and ensure the accuracy of tape unwinding. A reduction motor 4 is connected to the driving shaft 301. A reduction motor is connected to the driving shaft; the reduction motor provides the power for the rotation of the driving shaft. When unwinding the tape, the tape reel II rotates around the driving shaft group, and the driving shaft serves as the rotation support member of the tape reel II.

[0024] As Figure 2 shown in Embodiment 2, a double-outlet tape unwinding machine in a tunnel. On the basis of Embodiment 1, in this embodiment, the reduction motor 4 is connected to the tape unwinding rack 1 through a motor bracket 401 to provide support for the reduction motor, and the reduction motor 4 is in power transmission with the driving shaft 301 through a gear pair or a chain sprocket pair or a pulley pair. The reduction motor 4 performs power transmission through one of the above transmission mechanisms to provide power for the tape winding of the driving shaft group. In this embodiment, preferably, the driven shaft 201 and the driving shaft 301 can be square shafts, and corresponding square holes are provided on the reels of the tape reel I and the tape reel II. The square shafts are inserted into the corresponding square holes to achieve synchronous rotation of the tape reel and the corresponding square shaft.

[0025] In this embodiment, the tape reel I 8 has a total of four outlets (respectively a, b, c, d). Two outlets (a, b) form a free docking joint, and the other two outlets (c, d) are wound into the tape reel II 9. The free docking joint is used for vulcanization docking. While the tape reel I 8 rotates and unwinds the tape under the action of the tensioning vehicle, the driving shaft group 3 drives the tape reel II 9 to rotate actively, and the tape reel II 9 rotates in the opposite direction to the tape reel I 8 at the same rotation speed as the tape reel I 8.

[0026] In this embodiment, preferably, a plurality of groups of roller groups 7 corresponding to the tape reel I 8 and the tape reel II 9 are provided on the tape unwinding rack 1. Each group of roller groups 7 includes a left roller and a right roller symmetrically arranged on the left and right. The left roller and the right roller are respectively located on both sides of the tape reel I 8 and the tape reel II 9. The setting of the rollers prevents the tape from rubbing against the rack during rotation.

[0027] In addition, a wheel assembly 6 is provided at the bottom of the tape feeding rack 1 in this embodiment. The wheel assembly 6 cooperates with a pre-laid track 5. The wheel assembly 6 is installed on the tape feeding rack, and the tape feeding rack slides along the track through the wheel assembly. The track provides guidance for the movement of the tape feeding rack. When feeding the tape, the tape feeding rack is moved along the track under the belt rack to ensure that the center lines of the tape reel and the continuous belt conveyor are collinear.

[0028] As Figure 3 shown in Embodiment 3, a continuous belt conveyor vulcanizing tape feeding system includes a tape storage bin 10 and the double-ended tape feeding machine in the tunnel described in Embodiment 1 or 2; a vulcanizing platform 11 is provided between the tape storage bin 10 and the double-ended tape feeding machine in the tunnel; multiple vulcanizing platforms can be provided according to needs to improve the vulcanizing efficiency; a movable tensioning cart is provided in the tape storage bin 10. The tensioning cart is pulled by tightening the steel wire rope through frequency conversion tensioning.

[0029] In this embodiment, preferably, movable roller guiding frames 12 are provided between the tape storage bin 10 and the vulcanizing platform 11 and between the vulcanizing platform 11 and the double-ended tape feeding machine in the tunnel, which are used to support and guide the tape to ensure the smooth feeding of the tape and prevent the tape from rubbing against the rack.

[0030] During specific implementation, the tape is wound into a double-ended eye roll as Figure 1 shown in a wide area outside the tunnel. There are a total of 4 heads on the tape reel Ⅰ, two heads are exposed, and the other two are wound into the tape reel Ⅱ. Then it is transported to the tape feeding machine in the tunnel, and the tape reel Ⅰ is installed on the driven shaft of the driven shaft group through a hoisting device, and the tape reel Ⅱ is installed on the driving shaft of the driving shaft group. After the tape reels Ⅰ and Ⅱ are fixed on the tape feeding rack, the tape feeding rack is pushed under the belt body along the track. The tape is cut at the middle roller of the tape storage bin, and then the joint is pulled out to be vulcanized and bonded with the two free docking joints of the tape reel Ⅰ on the vulcanizing platform. On the vulcanizing platform, the four tape heads are vulcanized and bonded in pairs. After vulcanization is completed, the tape on the vulcanizing platform is moved to the idler rack.

[0031] When feeding the tape, first tighten the steel wire rope through frequency conversion tensioning to pull the tensioning cart of the tape storage bin, and then the tensioning cart winds the tape into the tape storage bin. At the same time, the tape reel Ⅰ rotates to feed the tape under the action of the tensioning cart. While the tape of the tape reel Ⅰ is being wound into the tape storage bin, the reduction motor operates to drive the driving shaft group to rotate the tape reel Ⅱ, and the tape reel Ⅱ rotates in the opposite direction to the tape reel Ⅰ at the same speed. Half of the tape in the tape reel Ⅰ is wound into the tape reel Ⅱ. The two tape reels rotate at the same time, which can effectively avoid the occurrence of tape stacking. After the tape of the tape reel Ⅰ is completely released, the reduction motor stops operating, and the tape of the tape reel Ⅱ is wound into the tape storage bin under the action of the tensioning cart until the tape of the tape reel Ⅱ is completely released, and the tape feeding work is completed.

[0032] The entire tape feeding process described above greatly reduces the working intensity of personnel in tape feeding. Double-head vulcanization and double-head tape feeding and rewinding also greatly improve the tape feeding efficiency, effectively enhancing the construction efficiency of the belt conveyor.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
