Description

Technical Field

[0001] The invention relates to the technical field of cable laying, and in particular to a cable laying device for electric power engineering construction. Background Art

[0002] In the construction of power projects, the long-distance transmission and laying of cables requires the use of cable laying machines and other conveying devices to assist in laying. The working principle of the cable laying machine is to generate a driving force to support the work under the operation of the internal motor, and drive two sets of relative conveyor belts to rotate through the driving wheel. The cable is clamped between the relative conveyor belts, and the cable moves forward driven by the conveyor belts.

[0003] In order to prevent the cable skin from being damaged during transportation, the conveyor belt used for conveying cables is often clamped with rubber blocks. After long-term use, the wear of the rubber may cause slippage, resulting in reduced transmission efficiency and kinetic energy loss. Especially in long-distance transportation and laying of large cables, it is usually necessary to install multiple cable laying machines for simultaneous traction. When one or several groups have insufficient clamping force, the traction load of other normal laying machines will be increased. When the traction force is insufficient, the laying speed of the cable will be reduced, causing the cable and the laying machine with insufficient clamping force to slide relative to each other. The slippage will cause resistance to the movement of the cable and increase the wear of the conveyor belt and cable.

[0004] In summary, there is an urgent need for a cable laying device for electric power engineering construction that can adaptively provide clamping force when slippage occurs between the laying machine and the cable, thereby solving the slippage problem. Summary of the invention

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to better understand the cable laying device for power engineering construction provided by the present embodiment, the existing cable laying device is briefly introduced below. In the existing scheme, the cable laying machine or cable conveyor is a machine for conveying cables. The machine drives the conveyor belt on the platform to rotate through a driving device, clamps the cable between two sets of conveyor belts, and makes the two conveyor belts approach each other by rotating the adjustment mechanism. When the two conveyor belts clamp the cable, the cable is driven to move in the rotation direction of the conveyor belt. When the rotation speed of the conveyor belt is greater than the travel speed of the cable, slippage occurs, affecting the forward speed of the cable. However, the prior art does not provide supporting measures for the laying machine to deal with slippage. Generally, the conveyor belt needs to be replaced regularly to reduce the probability of slippage. Slippage during travel cannot be easily detected. Therefore, the present invention will provide a corresponding structure on the basis of the existing cable laying machine to adaptively adjust the clamping state of the conveyor belt to the cable according to the feedback of the cable travel speed. When slippage occurs, increasing the clamping force of the conveyor belt can effectively prevent relative sliding. Specifically, as described below.

[0032] The transmission rod 21 is a threaded rod, the threads are not shown in the figure and the gear teeth on the corresponding figure are only for illustration.

The engagement method can be a clutch plate type friction engagement, etc. It should be understood that the above-mentioned detachable engagement is a prior art. In the initial state, the second connecting portion 2222 and the active turntable 221 remain in a separated state. When the second connecting portion 2222 moves down to engage with the active turntable 221, the active turntable 221 can drive the driven turntable 222 to rotate and cause the transmission rod 21 to rotate.

[0035] Please see attached Figure 4 , Figure 4 The differential rod of the cable laying device for power engineering construction of the present invention is a schematic diagram; the differential rod 23 includes a follower part 231, an active part 232, and a driven sleeve 233; the follower part 231 rotates following the movement of the cable 3, the active part 232 rotates following the conveyor belt 14, the driven sleeve 233 rotates following the active part 232, and when the rotation speeds of the active part 232 and the follower part 231 are inconsistent, the driven sleeve 233 can move along the active part 232 and the follower part 231; specifically, a plurality of straight teeth 2311 are evenly arranged around the axis at one end of the follower part 231, and it should be understood that the distance between the two straight teeth 2311 should be sufficient to allow the follower part 231 to rotate continuously under the drive of the cable 3, and an elastic pad is arranged on the side of the straight tooth 2311, which can effectively avoid the slipping phenomenon between the follower part 231 and the cable 3.

[0036] Please see attached Figure 5 , Figure 5The present invention is a schematic cross-sectional view of the driven sleeve of the cable laying device for power engineering construction, wherein the driven part 231 is provided with a differential moving groove 235, and the differential moving groove 235 is a guide groove structure which is cyclically arranged around the outer wall surface of the driven part 231 and connected end to end, and the differential moving groove 235 includes an upward section 2351 and a downward section 2352, and the driven sleeve 233 is sleeved on the outer wall surface of the driven part 231, and a moving guide column 2331 is provided on the inner wall of the driven sleeve 233, and the moving guide column 2331 is adaptively connected with the differential moving groove 235 and can move along the differential moving groove 235, and the driven part 231 is connected to the base 11 through a bearing, and preferably, the driven sleeve 233 is provided with a guide column 2331 on the inner wall of the driven sleeve 233. A plurality of movable guide columns 2331 are provided, and the number of movable guide columns 2331 is the same as the number of path cycles of the differential movable groove 235. Each movable guide column 2331 is located in the same plane. A sphere can be provided at the end of the movable guide column 2331 to facilitate sliding in the differential movable groove 235. A gear meshing with the active part 232 is provided on the driven sleeve 233. One end of the active part 232 is connected to a rotating shaft driving the conveyor belt 14 to rotate, so that the active part 232 always rotates with the conveyor belt 14. The active part 232 is a gear plate coaxial with the conveyor belt 14 and a cylindrical gear meshing therewith, so that the gear on the driven sleeve 233 meshes with the cylindrical gear and can move up and down along it.

[0037] The driven sleeve 233 is provided with a driving rod 234. When the driven sleeve 233 moves up and down, the driving rod 234 can drive the second connecting portion 2222 of the driven turntable 222 to engage with the active turntable 221. The driving rod 234 includes a telescopic control rod 2341 and a support rod 2342. One end of the telescopic control rod 2341 is movably connected to the driven sleeve 233. The movably connected connection includes the degrees of freedom of rotation and swing. Specifically, one end of the telescopic control rod 2341 is connected to the driven sleeve The outer wall surface of the cylinder 233 is connected by a bearing, and is radially connected to the outer wall of the bearing by a rotating shaft. Similarly, the other end of the telescopic control rod 2341 is connected to the second connecting portion 2222 with the same structure; and a support rod 2342 is connected to the telescopic control rod 2341, and the telescopic control rod 2341 can rotate around the support rod 2342. The other end of the support rod 2342 is connected to the shaft rod where the active turntable 221 is located through a bearing, so that the support rod 2342 can rotate around the shaft rod.

[0038] Preferably, in order to adapt to the diameters of different cables 3 and enable the straight tooth 2311 part of the follower part 231 to maintain good contact with the cable 3, in the present embodiment, the follower part 231 rotates with the position of the active part 232 as the center of the circle, and correspondingly, guide grooves and bolts for adjustment and fixation are provided on the base 11, and the connecting part of the support rod 2342 and the telescopic control rod 2341 is also provided with a long groove to provide freedom to cooperate with the adjustment of the position of the follower part 231. It should be understood that the cable laying device for power engineering construction of the present invention can also only detect cables 3 of one diameter. In this case, there is no need to set a position adjustment structure for the follower part 231.

[0039] It should be understood that in the present invention, the active part 232 is used to detect the rotation speed of the conveyor belt 14, the follower part 231 is used to detect the forward speed of the cable 3, and the driven sleeve 233 is used to convert the differential speed between the active part 232 and the follower part 231 into a cyclic movement in a certain direction to control the separation and engagement of the active turntable 221 and the driven turntable 222 on the clutch rod 22. In the embodiments listed in the present invention, please refer to the corresponding drawings for details. The active part 232 is composed of a toothed disc with the same diameter as the end of the conveyor belt 14 and a gear column meshed therewith. At this time, the gear disc on the driven sleeve 233 is also the same diameter as the toothed disc of the active part 232. A separate gear column is provided between the two to enable the driven sleeve The transmission direction of the cylinder 233 is the same as the rotation direction of the follower part 231, and at the same time it provides support for the up and down movement of the driven sleeve 233, and the rotation speeds of the two toothed discs with the same diameter that mesh with the gear column are also the same, and the driven sleeve 233 is coaxial with the follower part 231, so it can reflect the relative differential through the corresponding structure; it should be further explained that the linkage between the active part 232 and the driven sleeve 233 can also be driven by a sprocket. At this time, the relative position of the sprocket on the driven sleeve 233 and the sprocket of the active part 232 remains unchanged, and a movable sleeve with the movable guide column 2331 that can move up and down is provided in the driven sleeve 233, and the up and down movement of the movable sleeve is used to control the engagement of the corresponding device on the clutch rod 22.

[0040] The use of the present invention is as follows: the cable 3 is placed between the first clamping platform 12 and the second clamping platform 13, and a device such as a crank 211 that is conducive to rotating the transmission rod 21 can be set at one end of the transmission rod 21. The crank 211 can also be detachable to avoid affecting the subsequent automatic adjustment. The transmission rod 21 is rotated to make the first clamping platform 12 and the second clamping platform 13 gradually approach and clamp the cable 3. It should be understood that in the initial state, the driven turntable 222 is separated from the active turntable 221, so the rotation of the rotating rod will not interfere with the active turntable 221; the position of the follower rod is adjusted so that the part of the follower rod with straight teeth 2311 is always meshed with the outer surface of the cable 3, and the gear meshing of the active part 232 and the driven sleeve 233 can be maintained by the extension and retraction of the telescopic control rod 2341; in this embodiment, in order to ensure that the rotation speed of the active part 232 is consistent with the rotation speed measured by the follower part 231 The speed can be compared by comparing the speed of the driven sleeve 233 with the area where the differential moving groove 235 of the follower 231 is located. The diameter of the portion where the straight teeth 2311 of the follower 231 in contact with the cable 3 is located is the same as the diameter of the conveyor belt 14, so that when there is no slippage, the rotation speed of the follower 231 is the same as the rotation speed of the conveyor belt 14, that is, the same as the rotation speed of the active part 232. The diameter of the conveyor belt 14 refers to the width of the conveyor belt 14, that is, the diameter of the semicircle at the end of the conveyor belt 14. It should be understood that when the diameters are different, the final speed comparison can be achieved by setting a gear set. The speed comparison means that when there is no slippage, the differential moving groove 235 and the moving guide column 2331 are relatively stationary. In this embodiment, the driving device drives the shaft located at the semicircular end of the conveyor belt 14 to rotate through a transmission mechanism such as a gear set and a chain, and the lower end of the shaft is connected to the active part 232.

[0041] When the rotation speed provided by the conveyor belt 14 is consistent with the travel speed of the cable 3, the rotation speeds of the driven sleeve 233 and the follower 231 are also the same, so that the movable guide column 2331 and the differential movable groove 235 are relatively stationary, and the movable guide column 2331 is located at the starting end of the upstream section 2351 of the differential movable groove 235. At this time, the driven turntable 222 and the active turntable 221 remain separated. When slippage occurs, the travel speed of the cable 3 must be less than the rotation speed provided by the conveyor belt 14, resulting in a differential between the driven sleeve 233 and the follower 231, so that the movable guide column 2331 rotates relative to the differential movable groove 235. Please refer to the attached figure. Figure 6 , Figure 6Schematic diagram of the differential rod of the cable laying device for power engineering construction of the present invention in the upward state, and due to the restriction of the differential moving groove 235, the moving guide column 2331 moves along the upward section 2351, thereby driving the driven sleeve 233 to move upward, at this time, driven by the lever action of the driving rod 234, the second connecting portion 2222 of the driven rotating disk 222 moves downward, and the telescopic control rod 2341 can be telescoped accordingly to realize that the connection positions of the two ends are only moved up and down, please see the attached Figure 7 , Figure 7 This is a schematic diagram of the clutch rod in the engaged state of the cable laying device for power engineering construction according to the present invention. When the movable guide column 2331 moves to the upper vertex of the differential moving groove 235, the second connecting portion 2222 engages with the active turntable 221, and the conveyor belt 14 of the active turntable 221 drives the rotation of the transmission rod 21, thereby making the first clamping platform 12 and the second clamping platform 13 approach each other, thereby increasing the clamping force on the cable 3 to control slippage.

[0042] In order to control the approach distance and prevent excessive squeezing of the cable 3 due to excessive approach, the driven turntable 222 contacts the active turntable 221 only when the movable guide column 2331 is located at the vertex of the upward segment 2351. At this time, the differential speed between the driven sleeve 233 and the follower 231 still exists, that is, the movable guide column 2331 continues to enter the downward segment 2352 and separates from the vertex of the upward segment 2351, which is the intersection of the upward segment 2351 and the downward segment 2352. At this time, the second connecting portion 2222 separates from the active turntable 221 and approaches the knot. It should be understood that when the slippage disappears after approaching, the driven sleeve 233 and the follower 231 resume a relatively static state, and when the speed is still inconsistent after approaching, the mobile guide column 2331 will move to the top of the next section of the upward section 2351 again until the speed difference problem is finally solved; the running distance between the upward section 2351 and the downward section 2352 is the correction threshold. When the differential speed is large, the adjustment is relatively fast, and when the differential speed is small, the adjustment is relatively slow. When there is an accidental slippage, it will not be adjusted immediately, which can prevent excessive extrusion. It should be noted that the downward section 2352 can have a certain slope, and can also be vertical downward. When the downward section 2352 is vertically downward, when it passes the top of the upward section 2351, it can be directly restored to the initial state with the spring of the second connecting part 2222 and the first connecting part 2221, so that the mobile guide column 2331 returns to the starting point of the next section of the upward section 2351.

[0043] It should be noted that: the cable laying device for power engineering construction of the present invention includes a laying machine body 1 for conveying a cable 3, and a feedback anti-skid system 2 that can detect and adjust the laying machine body 1; the feedback anti-skid system 2 includes a transmission rod 21, a clutch rod 22, and a differential rod 23, and the differential rod 23 can detect and feedback the speed difference between the travel speed of the cable 3 and the conveyor belt 14, so that when there is a differential speed, the clutch rod 22 controls the rotation of the transmission rod 21, thereby adjusting the laying machine body 1. The distance between the upper and lower conveyor belts 14 increases the pressure on the cable 3, solves the differential problem caused by slipping, and effectively ensures the problem of reduced operating efficiency caused by slipping during operation; in a conveying system composed of multiple laying devices, it can prevent the load of other laying devices from increasing due to slipping; the feedback anti-skid system 2 includes a transmission rod 21, a clutch rod 22, and a differential rod 23. The feedback anti-skid system 2 includes a driving part 231, an active part 232, and a driven sleeve 23 3, the following part 231 can convert the travel speed of the cable 3 into the rotation speed of the following part 231, and the rotation speed of the active part 232 is the same as that of the conveyor belt 14; the rotation speed of the following part 231 and the active part 232 can be compared through the driven sleeve 233, and the differential reaction is converted into the rise and fall of the driven sleeve 233 by the cooperation of the moving guide column 2331 and the differential moving groove 235, thereby controlling the separation and engagement of the driven rotating disk 222 and the active rotating disk 221 in the clutch rod 22, thereby adjusting the cable 3 Clamping force; The differential moving groove 235 includes an upward section 2351 and a downward section 2352, and is evenly arranged around the side wall of the follower 231. The stroke lengths of the upward section 2351 and the downward section 2352 provide an error threshold. Adjustment will only occur when continuous or multiple slippage occurs, avoiding unnecessary approach to cause excessive pressure on the cable 3. The upward section 2351 and the downward section 2352 are circulated in sequence, and multiple, small-amplitude displacement fine-tuning can be implemented, which can also prevent over-adjustment. Straight teeth 2311 are arranged between the follower 231 and the outer surface of the cable 3 to follow the movement of the cable 3. Obviously, relative to the contact between the cylindrical surface and the cable 3, the straight tooth 2311 structure can prevent the follower 231 and the cable 3 from slipping, and the side of the straight tooth 2311 is provided with an elastic pad, which is also used to prevent the follower 231 and the cable 3 from slipping, and preferably, the elastic pad is made of the same material as the part of the conveyor belt 14 that contacts the cable 3.
