Description

[0001] The invention relates to the technical field of communication pipeline construction, and in particular to an automatic laying device for communication pipelines. Background Art

[0002] The communication pipeline project refers to the project of building pipelines specifically for the construction of communication lines in urban areas, so as to avoid building electric poles and wires on both sides of the streets to ensure the beauty of the urban area. The existing laying of communication pipelines is to dig holes on the ground to lay pipes, and then use soil to fill the pipes to achieve the laying of communication pipelines. Communication lines are laid in the pipelines, and the pipelines play a protective role for the communication lines.

[0003] In the prior art, the position of the communication line is further controlled by controlling the position of the vehicle. However, due to the large differences in conditions at each laying site and complex road conditions, it is difficult to control the vehicle to move stably along the set path. Since the communication line is wrapped around the outside of the reel before laying, the communication line will bend when it is laid, which causes the length of the laid line to be greater than the length to be laid, resulting in a large laying error. During actual laying, the staff also needs to pull and adjust the position of the communication line. Summary of the invention

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] Example: See Figure 1 - Figure 7 , an automatic laying device for communication pipelines, including a carrier 1, a bearing mechanism and a wire drum 3, the bearing mechanism including two first fixing seats 2 installed on one side of the top of the carrier 1 by bolts and a key pin shaft 4 installed between the two first fixing seats 2, the wire drum 3 is installed on the outside of the key pin shaft 4, when the wire drum 3 needs to be replaced, the first fixing seat 2 away from the first gear 16 is removed, and then the used wire drum 3 is removed from the key pin shaft 4, and then a new wire drum 3 is installed, and finally the first fixing seat 2 just removed is installed.

[0048] Also includes:

[0049] A limiting mechanism is installed on the top of the carrier 1 and is used to limit the communication line 301 in the cable drum 3. The limiting mechanism includes two guide balls 5 rotatably connected to the top of the carrier 1 and a threading groove 6 extending through the guide balls 5. The lubrication mechanism is located between the two guide balls 5.

[0050] An adjustment mechanism, which is installed on the top of the carrier 1 and is used to adjust the outlet angle of the communication line 301, the adjustment mechanism includes a first motor 7 installed inside the carrier 1, a crank 8 fixedly sleeved on the outside of the output shaft of the first motor 7, a first guide wheel group 9 rotatably connected to the other end of the crank 8, a bracket 40 installed at the bottom of the crank 8, and a second guide wheel group 10 rotatably connected to the outer wall of the bracket 40; the communication line 301 first passes through the inside of a threading groove 6, then passes through the lubrication mechanism, another threading groove 6 and the inside of the first guide wheel group 9 in sequence, and finally passes through the inside of the second guide wheel group 10;

[0051] Since the conditions at each laying site vary greatly, the laying position of the communication line 301 may be at any angle around the carrier 1. Therefore, after the communication line 301 is threaded and the outlet end is fixed, the first motor 7 is controlled to drive the crank 8 to rotate, and then the position of the first guide wheel group 9 and the second guide wheel group 10 are adjusted in cooperation with the bracket 40 to make the line laying position more accurate.

[0052] The locking mechanism is installed inside the carrier 1 and is used to control the start and stop of the key pin shaft 4 and the wire drum 3. The locking mechanism includes a first transmission shaft 11 rotatably connected to the inside of the carrier 1, a first reciprocating screw 12 fixedly sleeved on the outside of the first transmission shaft 11, a slider 13 screwed on the outside of the first reciprocating screw 12, a plurality of connecting rods 14 hinged on the top of the slider 13, and a rack 15 hinged on the other end of the plurality of connecting rods 14, the top of the rack 15 extends to the outside of the carrier 1; a first gear 16 is fixedly sleeved on the outside of the key pin shaft 4, and the rack 15 meshes with the first gear 16 when moving upward; a plurality of guide rods 17 are fixedly connected to the inner wall at the top of the carrier 1, and the rack 15 is also slidably sleeved on the outside of the plurality of guide rods 17; the first transmission shaft 11 is connected to the driving mechanism;

[0053] Since the communication line 301 is wound around the outside of the wire drum 3 before being released, the communication line 301 will bend when it is released, which causes the length of the released line to be greater than the length that is laid. Therefore, when releasing the line, the present embodiment drives the first transmission shaft 11 to rotate through an intermittent control driving mechanism, and the first reciprocating screw 12 rotates accordingly, thereby driving the slider 13 to move from the right end of the first reciprocating screw 12 to its left end. In this process, the rack 15 is driven to move upward through the connecting rod 14 and meshes with the first gear 16, and the slider 13 is driven to move upward through the connecting rod 14. The block 13 stops moving, and the rack 15 also stops moving, thereby locking the key pin shaft 4 and the wire drum 3, so that the wire drum 3 will not continue to rotate to pay out the wire. As the carrier 1 continues to move forward, the released communication line 301 is tightened, and then the driving mechanism is controlled to drive the first reciprocating screw 12 to rotate, driving the slider 13 to move right and reset, driving the rack 15 to move downward, and releasing the lock on the wire drum 3, so that the wire drum 3 can continue to pay out the wire. By tightening the wire once at the same distance, the problem of large error in the length of the wire being paid out due to bending of the communication line 301 can be prevented.

[0054] A lubricating mechanism is installed on the top of the carrier 1 and is used to apply lubricant to the outside of the communication line 301. The lubricating mechanism includes two second fixing seats 18 fixedly connected to the top of the carrier 1, a sleeve 19 rotatably connected to the inside of the two second fixing seats 18, a smearing cotton sleeve 20 installed inside the sleeve 19, an annular supply groove 21 provided on the outside of the sleeve 19, and a sealing ring 22 fixed to the outer wall of one of the second fixing seats 18; a through groove is provided inside the smearing cotton sleeve 20; a plurality of material guide grooves are provided on the inner side wall of the sleeve 19, and the plurality of material guide grooves are all connected to the annular supply groove 21, and are used to guide the lubricant inside the annular supply groove 21 into the inside of the smearing cotton sleeve 20; the sealing ring 22 is also rotatably sleeved on the outside of the sleeve 19, and is used to seal the annular supply groove 21; the sleeve 19 is connected to the driving mechanism;

[0055] The sleeve 19 is driven to rotate by the driving mechanism, and the smearing cotton sleeve 20 rotates along the outside of the communication line 301 during the movement, and the lubricant is evenly applied to the outside of the communication line 301, and the lubricant is continuously supplied to the smearing cotton sleeve 20 by the supply mechanism;

[0056] When the sleeve 19 rotates, the sealing ring 22 does not rotate therewith, and the discharge pipe 30 also remains stationary.

[0057] The supply mechanism is installed inside the carrier 1 and is used to provide lubricant to the lubricating mechanism. The supply mechanism includes a guide cylinder 23 fixed to the inner wall of the top of the carrier 1, a piston 24 installed inside the guide cylinder 23, a support block 25 fixed inside the guide cylinder 23, a second reciprocating screw 26 rotatably connected to the outer wall of one side of the support block 25, a driving block 27 screwed to the outside of the second reciprocating screw 26, and two driving rods 28 fixed to the outer wall of one side of the driving block 27; the other end of the second reciprocating screw 26 The end is connected to the driving mechanism; the driving rod 28 is arranged through the support block 25 and is slidably connected to the support block 25, the driving rod 28 is fixedly connected to the piston 24, a storage box 31 is installed inside the carrier 1, a feed pipe 29 and a discharge pipe 30 are installed at one end of the guide cylinder 23, the other end of the feed pipe 29 is connected to the storage box 31, a first one-way valve 32 is installed on the feed pipe 29, a second one-way valve 33 is installed on the discharge pipe 30, and the other end of the discharge pipe 30 is connected to the annular supply groove 21;

[0058] The first one-way valve 32 is provided so that the lubricant in the storage box 31 can enter the guide cylinder 23 through the feed pipe 29, while the lubricant in the guide cylinder 23 cannot return to the storage box 31 through the feed pipe 29; the second one-way valve 33 is provided so that the lubricant in the guide cylinder 23 can enter the annular supply groove 21 through the discharge pipe 30, while the lubricant in the annular supply groove 21 cannot return to the guide cylinder 23 through the discharge pipe 30;

[0059] The second motor 34 is controlled to drive the second reciprocating screw 26 to rotate, thereby driving the driving block 27 to move back and forth along the outside of the second reciprocating screw 26. In this process, the piston 24 is driven to move back and forth inside the guide cylinder 23 through the driving rod 28;

[0060] When the piston 24 moves to the left, the lubricant inside the storage box 31 is drawn into the guide cylinder 23 through the feed pipe 29. When the piston 24 moves to the right, the lubricant inside the guide cylinder 23 is introduced into the annular supply groove 21 through the discharge pipe 30. The lubricant entering the annular supply groove 21 penetrates into the coating cotton sleeve 20 through the guide groove.

[0061] A driving mechanism, which is installed inside the carrier 1 and is used to drive the locking mechanism, the lubricating mechanism and the supply mechanism to operate respectively, and the driving mechanism includes a second motor 34 installed on the inner wall of the top of the carrier 1, a second gear 35 fixedly sleeved on the outside of the output shaft of the second motor 34, and a first one-way gear 36 installed on the outside of the sleeve 19, and the second gear 35 is meshed with the first one-way gear 36;

[0062] The second motor 34 is controlled to drive the second gear 35 to rotate forward, and the second gear 35 is meshed with the first one-way gear 36 to drive the sleeve 19 to rotate. At this time, the second one-way gear 38 also rotates, but the first transmission shaft 11 does not rotate.

[0063] One end of the output shaft of the second motor 34 is fixedly connected to one end of the second reciprocating screw 26;

[0064] When the second motor 34 is started, it drives the second reciprocating screw 26 to rotate synchronously.

[0065] The driving mechanism also includes a second transmission shaft 37 rotatably connected to the outer wall of one side of the storage box 31, a second one-way gear 38 installed on the outside of the second transmission shaft 37, and a transmission member 39 transmission-connected between the second transmission shaft 37 and the first transmission shaft 11, and the second one-way gear 38 is meshed with the second gear 35; the transmission member 39 includes two synchronous wheels respectively fixedly sleeved on the outside of the second transmission shaft 37 and the first transmission shaft 11, and a synchronous belt transmission-connected to the outside of the two synchronous wheels;

[0066] The second motor 34 is controlled to drive the second gear 35 to reverse, and the second gear 35 is meshed with the second one-way gear 38 to drive the second transmission shaft 37 to rotate. At this time, the first one-way gear 36 also rotates, but the sleeve 19 does not rotate. During the rotation process, the second transmission shaft 37 drives the first transmission shaft 11 to rotate through the transmission connection of the transmission member 39.

[0067] Working principle: When in use, first pass one end of the communication line 301 outside the wire drum 3 through a wire threading groove 6, then pass through the lubrication mechanism, another wire threading groove 6 and the first guide wheel group 9 in turn, and finally pass through the second guide wheel group 10, and then fix the outlet end inside the laying channel, and control the first motor 7 to drive the crank 8 to rotate, and then cooperate with the bracket 40 to adjust the position of the first guide wheel group 9 and the second guide wheel group 10 to make the wire release position more accurate, control the carrier 1 to move forward at a constant speed, and the wire drum 3 and the key pin shaft 4 rotate accordingly to release the communication line 301, and at the same time, drive the sleeve 19 to rotate through the driving mechanism, and the cotton sleeve 20 rotates along the outside of the communication line 301 during the movement, and the lubricant is evenly applied to the outside of the communication line 301, and the lubricant is continuously provided to the cotton sleeve 20 through the supply mechanism. Because the communication line 301 is wound around the outside of the wire drum 3 before releasing the line, the communication line 301 will come out when it is released. The problem of bending occurs, which causes the length of the line to be paid out to be greater than the length that is laid. Therefore, when paying out the line, the present embodiment intermittently controls the driving mechanism to drive the first transmission shaft 11 to rotate, and the first reciprocating screw 12 rotates accordingly, thereby driving the slider 13 to move from the right end of the first reciprocating screw 12 to its left end. In this process, the rack 15 is driven upward by the connecting rod 14 and meshes with the first gear 16. The slider 13 stops moving accordingly, and the rack 15 also stops moving accordingly, thereby locking the key pin shaft 4 and the wire drum 3, so that the wire drum 3 will not continue to rotate to pay out the line. As the carrier 1 continues to move forward, the released communication line 301 is tightened, and then the driving mechanism is controlled to drive the first reciprocating screw 12 to rotate, driving the slider 13 to move right and reset, driving the rack 15 to move downward, releasing the lock on the wire drum 3, so that the wire drum 3 can continue to pay out the line. By tightening the line once at the same distance, the problem of large error in the length of the line paid out caused by the bending of the communication line 301 can be prevented.
