Description

Technical Field

[0001] The utility model relates to a laying device, in particular to an adjustable auxiliary device for facilitating cable laying on a bridge. The utility model is suitable for assisting the laying and installation of cables, and is especially used to assist in achieving safe and reliable installation of cables on a bridge, thereby facilitating cable laying on the bridge. The utility model belongs to the technical field of cable installation and traction. Background Art

[0002] Generally speaking, cable laying is a major part of any electrical and electromechanical construction project, and there are many situations where cables need to be pulled and straightened before laying. During cable laying, because the cables are thick and difficult to bend, and their weight is heavy, pulling them is difficult. Furthermore, during use, the commonly used method for pulling and straightening the cables is to manually straighten them as they are pulled out, which requires increased labor and results in limited straightening results.

[0003] Although tractors are currently used as auxiliary equipment in existing technologies, they generally have a single function or a complex structure, requiring manual labor to pull the cable, which is labor-intensive. Manual control of the cable laying position is often required, reducing work efficiency. Furthermore, manual labor is required to push the tractor to the designated position to facilitate laying.

[0004] It can be seen that although a laying device is usually used to lay cables during the current cable laying process, the existing bridge cable laying device requires manual adjustment of the height of the traction mechanism when laying cables at different heights due to the high height of the bridge. It is even necessary to frequently install or remove the cable laying device at any time to achieve cable laying at different construction locations. Since the laying of bridge cables is complicated and the heights are different, the cable traction mechanism needs to be adjusted frequently, which is more complicated to operate and reduces the cable laying efficiency. If the height adjustment is inaccurate, it will also affect the laying quality of the cable and even pose a major safety hazard.

[0005] In summary, the existing cable laying mainly has the following defects:

[0006] 1. Space occupation. Traditional cable laying methods may require a lot of space, especially in complex building structures or narrow passages, which may cause space waste and design limitations;

[0007] 2. Difficulty in maintenance. In some environments that require frequent maintenance and overhaul, improper cable laying may lead to maintenance difficulties, increasing maintenance costs and time;

[0008] 3. Safety hazards. Traditional cable laying methods may pose safety hazards. For example, cables exposed to the outside are prone to mechanical damage, chemical corrosion, or accidental contact.

[0009] 4. Inefficiency: In some cases, traditional cable laying methods may result in irregular and disorganized wiring, affecting cable transmission efficiency;

[0010] 5. Poor aesthetics: Traditional cable laying methods may result in uneven cable layout and unsightly appearance;

[0011] After searching, the Chinese utility model patent with the announcement number CN218201417U discloses an auxiliary device for facilitating the laying of cables on a bridge, comprising a mounting plate (1), characterized in that: a first mounting seat (11) is fixedly connected to the mounting plate (1), a second mounting seat (12) is slidably connected to the mounting plate (1), a rotating shaft (31) for placing a cable roller is rotatably connected to the first mounting seat (11) and the second mounting seat (12), two vertical plates (4) are symmetrically fixedly connected to the mounting plate (1), and the two vertical plates (4) are symmetrically fixedly connected to the mounting plate (1). A first straightening roller (41), a second straightening roller (42) and a third straightening roller (43) are rotatably connected between the vertical plates (4). The first straightening roller (41), the second straightening roller (42) and the third straightening roller (43) are all provided with grooves for matching with the cables, and the width of the groove on the second straightening roller (42) is greater than that of the first straightening roller (41) and smaller than that of the third straightening roller (43). The second straightening roller (42) is located between the first straightening roller (41) and the third straightening roller (43), and the third straightening roller (43) is closest to the rotating shaft (31). Although this structure has a significant effect on cable straightening, it is complex in structure and the device is not mobile. The height of the device cannot be adjusted according to the height change of the bridge frame. The flexibility and safety of use are poor, the space occupied is large, and the efficiency is low during actual use. In short, it is often very inconvenient and there is a possibility of overturning. In short, it is often very inconvenient.

[0012] Therefore, the key to solving the above technical problems is to develop an adjustable auxiliary device that is convenient for laying cables in bridges and has high practicality and strong working reliability. Utility Model Content

[0060] The working principle is: before using the above-mentioned adjustable auxiliary device for laying cables on the bridge, the already manufactured device needs to be installed as a spare.

[0061] Before installation, the operator only needs to carry the utility model to the designated construction site by hand or with corresponding handling equipment and place it there for installation. During installation, first, the operator only needs to move the utility model to the location where the cables are to be laid;

[0062] Then, the operator, in combination with the position of the cable wiring, holds the handrail (37) provided on the cable straightening mechanism (3) with both hands to place the placing rod (31) and the telescopic rod (32) on the outer wall of the bridge frame, so that the end of the telescopic rod (32) contacts the bridge frame, and adjusts the length of the telescopic rod (32) in the placing rod (31) to meet the height of the bridge frame. After adjusting to the appropriate position, the placing rod (31) and the telescopic rod (32) are connected as a whole by using the latch (36). At the same time, the operator can also adjust the hinge seat (35) according to the actual installation process, and the hinge seat (35) is rotatably connected to the placing rod installation port. After determining the placing angle of the placing rod (31) and the base (1), the operator tightens the locking member (6) so that the end of the locking member (6) is tightly fixed to the hinge seat (35), thereby fixing the placing angle of the placing rod (31) and the base (1).

[0063] Then, after the installation is completed, the winding drum (7) is installed on the placement bracket (21) through the placement openings coaxially opened on both sides of the placement bracket (21). In order to fix it firmly, the placement opening can be fixed with a locking piece, or a removable installation shaft is provided on the placement bracket (21), and the hollow hole of the winding drum (7) is passed through the installation shaft and placed on the placement bracket (21). Then, the two ends of the installation shaft are fixed;

[0064] Finally, according to the needs of wiring, the operator adjusts the sliding assembly (4) so that the slide plate (41) slides to the corresponding position in the slide groove (11), thereby fixing the sliding straightening member (43) at a suitable position. At the same time, the guide assembly (5) is also adjusted to a suitable position. After the adjustment is completed, the cable wiring or laying work can be carried out.

[0065] When laying the cable, tear open the outer packaging of the cable reel, pull out part of the cable (8), lead out the free end of the cable (8) from the winding reel (7), pass the head of the cable (8) through the sliding straightening member (43) area, leave a part of the cable (8), and then adjust and fix the cable straightening member (33) on the sliding straightening member (43) to facilitate the initial pulling and straightening of the cable (8), and then pass the cable (8) through the guide roller (52) on the guide assembly (5) and the cable straightening member (33) on the cable straightening mechanism (3) in sequence, and at the same time, adjust the straightening roller (332).

[0066] When adjusting and fixing the cable straightening mechanism (3), since each set of cable straightening parts (33) is composed of two identical straightening rollers (332), the roller shaft can move in the chute, driving the straightening roller (332) to move to a suitable position, and the cable (8) is stuck between the two straightening rollers (332). During operation, the lower straightening roller (332) can be moved and adjusted first. After it is moved to a suitable position, the fastening bolts 45 at both ends of the lower straightening roller (332) are wound around the threaded screw at the end of the rolling shaft 43 and tightened until they are tightly against the support plate (41) to fix the position; then the upper straightening roller (332) is slid to adapt to the diameter of the cable (8), and the fastening bolts at both ends of the upper straightening roller (332) are wound around the threaded screw on the rolling shaft and tightened until they are tightly against the support plate, thereby fixing the straightening roller (332) and preventing it from moving.

[0067] After the cable straightening mechanism (3) is adjusted and fixed, the head of the cable (8) is pulled forward to drive the cable (8) behind to come out from the winding drum (7), pass through the sliding assembly (4) and the guide assembly (5) in sequence, and finally be pulled forward along the cable straightening mechanism (3) to achieve the cable pulling and straightening effect.

[0068] According to the straightening requirements, multiple groups of straightening rollers (332) can be provided to enhance the straightening effect on the cable.

[0069] In addition, the pulling direction of the cable (8) can be guided and straightened by adjusting the height of the fixed positions of multiple groups of straightening rollers (332) according to the height requirements of the pulling straightening laying.

[0070] During the laying process, as the cable laying time goes by, when there is not much cable (8) left on the winding drum (7), and the utility model is tilted forward due to concerns about gravity, the operator only needs to first loosen and remove the top tightening member (92), and then use the handle (94) to pull out the counterweight device (9) set at the lower rear of the base (1), so that the counterweight frame (93) extends outward, thereby achieving balanced weight through the counterweight frame (93), providing appropriate counterweight, avoiding the device from tilting forward or tipping over, balancing the weight of the lifting object, and ensuring that the crane maintains a balanced state during operation; it can reduce the force on the cable auxiliary laying device itself, reduce its load, extend the service life of the mechanical equipment, reduce maintenance costs, make the cable auxiliary laying device more stable, reduce swing and vibration, reduce swing caused by wind or other external factors, ensure the safety and reliability of the lifting operation, and improve the accuracy and efficiency of the operation.

[0071] Finally, as time goes by, when all the cables (8) are laid, the operator only needs to first collect the remaining cables (8) onto the winding drum (7) and store them again. Finally, the cable straightening mechanism (3) is lowered and separated from the outer wall of the bridge frame by the handrail (37). At the same time, the telescopic rod (32) is adjusted and retracted into the placement rod (31), and the locking member (6) is used to tighten it in and out again. After cleaning and repairing each component, the operator moves the utility model to a designated tool storage warehouse for storage in preparation for the next cycle.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0118] In summary, the more specific implementation methods of the present invention are:

[0119] Example 1

[0120] As the instruction manual Figure 1 To the instruction manual Figure 10 An adjustable auxiliary device for facilitating cable laying on a bridge is shown, comprising:

[0121] The base 1 has a slide groove 11 in the middle thereof;

[0122] The cable rack 2 is adjustably mounted on one end of the base 1;

[0123] A cable straightening mechanism 3 is rotatably connected to the other end of the base 1;

[0124] Sliding assembly 4, sliding assembly 4 is slidably installed in the sliding groove 11;

[0125] A guide assembly 5 connected between the sliding assembly 4 and the cable straightening mechanism 3;

[0126] The rotating end of the cable straightening mechanism 3 is connected to a locking member 6 .

[0127] Further, such as Figure 6 As shown, the cable rack 2 includes:

[0128] The bracket 21 is placed, and two sides of the bracket 21 are coaxially provided with placement openings for placing the winding reel 7;

[0129] The adjusting assembly 22 is composed of an adjusting sleeve, a supporting column, and a tightening member threadedly connected to the adjusting sleeve;

[0130] The lower end of the adjusting sleeve is connected to the middle of one end of the base 1 , one end of the supporting column is connected to the middle of the lower end of the placement bracket 21 , and the other end of the supporting column is sleeved in the adjusting sleeve.

[0131] Furthermore, since the cable rack 2 is provided with an adjustment component 22, flexibility is achieved on the one hand: by providing the adjustment component 22 with an adjustable height structure, the height of the cable can be flexibly adjusted according to actual needs and changes in the wiring environment to adapt to different needs and conditions;

[0132] On the other hand, since the cable rack can be adjusted in height as needed, it is suitable for wiring occasions with various height requirements, which improves its scope of application and flexibility; on the other hand, in terms of space utilization, setting up an adjustable height structure can better utilize space, making the cable layout more compact and effective, saving space costs; on the other hand, in terms of safety, by adjusting the height structure, the cable layout can be made more standardized and neat, reducing the safety hazards caused by the different heights of cables. At the same time, by adjusting the height, the cables can be made easier to access and maintain, reducing the workload of maintenance personnel, improving maintenance efficiency, and having strong applicability.

[0133] Specifically, such as Figure 6 As shown, the lower end of the placement bracket 21 is also symmetrically connected to a buffer limiter 23; the buffer limiter 23 includes a buffer sleeve, a spring and a connecting sleeve, the lower end of the buffer sleeve is connected to the base 1, the upper end of the connecting sleeve is connected to the lower end of the placement bracket 21, one end of the spring is sleeved in the buffer sleeve, and the other end of the spring is sleeved in the connecting sleeve, wherein the lower end of the connecting sleeve is sleeved in the buffer sleeve.

[0134] In the present invention, since a buffer limiter 23 is provided, on the one hand, cable protection is achieved. The buffer limiter 23 can reduce the vibration and impact of the cable during transportation and installation, thereby protecting the cable from mechanical damage and wear and increasing safety. By providing the buffer limiter 23, dangerous impact forces generated when the cable runs at high speed or stops suddenly can be avoided, thereby improving the safety of cable laying. The buffer limiter can reduce the bumps and vibrations that the cable is subjected to during transportation and installation, thereby improving the reliability and stability of the cable line. Since the buffer limiter can reduce the vibration and impact of the cable, the service life of the cable can be extended, maintenance costs can be reduced, and the vibration and noise of the cable during transportation and installation can be reduced, thereby reducing the impact on the surrounding environment.

[0135] Further, such as Figure 8 As shown, the cable straightening mechanism 3 includes:

[0136] A placement rod 31, one end of which is provided with a mounting opening for connecting to a hinged seat 35;

[0137] The telescopic rod 32 is slidably connected to the display rod 31;

[0138] Several cable straightening members 33 are coaxially connected to the placement rod 31;

[0139] A guide wheel 34 rotatably connected to the non-connected end of the telescopic rod 32 ;

[0140] The hinge seat 35 is rotatably connected to the mounting opening of the placement rod;

[0141] The locking member 6 is threadedly connected to one side of the rotating end of the placement rod 31, and the end of the locking member 6 is fastened by a fastening nut.

[0142] In the present invention, after determining the placement angle of the placement rod 31 and the base 1, the locking member 6 is tightened, and then the end of the locking member 6 is tightly fixed to the hinge seat 35, thereby fixing the placement angle of the placement rod 31 and the base 1.

[0143] In the present invention, the locking member 6 includes a bolt and a nut, and the nut is screwed and installed on the end of the bolt to play a tightening and limiting role, wherein the bolt is a hexagonal bolt or a flat head bolt, and the nut is a hexagonal nut or a flat head nut.

[0144] In the present invention, the cable straightening mechanism 3 is provided, which can straighten the cable. The cable may be bent or twisted during transportation and installation. The cable straightening mechanism can be used to straighten the cable and restore it to a predetermined shape and direction, which helps to ensure the correct installation and transmission performance of the cable.

[0145] On the other hand, the cable straightening mechanism 3 is provided to reduce the stress on the cable, thereby solving the problem that the stress on the cable during transportation and installation may cause deformation and damage to the cable, and even affect its electrical performance. Therefore, the cable straightening mechanism can reduce the stress on the cable and protect the cable from damage by properly adjusting the position and direction of the cable.

[0146] On the other hand, the cable straightening mechanism 3 is provided to improve the cable wiring effect. The cable straightening mechanism can help arrange the cables correctly and neatly in the required positions, avoid cable crossing, staggered or messy wiring, thereby helping to improve the cable wiring effect and aesthetics, reduce cable interference and failure risks, achieve high-efficiency cable straightening, reduce cable stress and improve cable wiring effect, so as to ensure the normal operation and long-term reliability of the cables.

[0147] More importantly, the cable straightening mechanism 3 of the utility model also serves as an adjustable cable laying and conveying bracket, which can be adjusted to a suitable position for use according to the height of the bridge, thereby improving the flexibility of wiring, saving time and cost, improving safety, facilitating maintenance and optimizing space utilization. It is a more intelligent and humane cable arrangement method.

[0148] The cable straightening mechanism 3 can be adjusted in height and angle according to actual needs and changes in the wiring environment, making cable laying more flexible and adaptable to wiring situations with different height and angle requirements. At the same time, since the cable straightening mechanism 3 can be adjusted as needed, construction efficiency can be improved, wiring time can be saved, and material waste can be reduced, thereby lowering costs.

[0149] On the other hand, the cable straightening mechanism 3 can ensure that the cable is laid at the correct height and angle, reduce the tension and bending of the cable, thereby reducing the risk of cable damage and failure, and can better utilize space, making the cable layout more compact and effective, saving space costs while making it easier to access and maintain, reducing the workload of maintenance personnel, and improving maintenance efficiency.

[0150] Specifically, such as Figure 8 As shown, it also includes a latch 36 and handrails 37 symmetrically arranged at the non-installation end of the display rod 31, and an anti-slip sheath is provided on the handrail 37, wherein the latch 36 is connected to one of the handrails 37 by a rope.

[0151] In the present invention, the anti-slip cover is a rubber cover, and a plurality of rubber protective protrusions of a connected structure are provided on the outer surface of the rubber cover. The rubber protective protrusions are granular or annular protrusions. Therefore, since the anti-slip cover is provided on the hand-holding part of the armrest 37, it can protect the operator's hands from being worn due to long-term work, thereby ensuring the safety of construction.

[0152] Specifically, such as Figure 8 As shown, the placing rod 31 is a square columnar structure with one end open and the other end closed and hollow inside. A latch hole is coaxially formed through the open end of the placing rod 31, and a latch 36 is connected to the latch hole.

[0153] The telescopic rod 32 is provided with a plurality of adjustment holes at equal or unequal intervals.

[0154] The outer surface of the guide wheel 34 is also provided with a protective layer;

[0155] Among them, a plurality of cable straightening members 33 are connected to the placement rod 31 at equal or unequal distances.

[0156] In the present invention, the design of the guide wheel 34 realizes the guidance of the cable on the one hand: the cable guide wheel can effectively guide the cable to move along a predetermined path, ensuring that the cable is guided along the correct trajectory during the wiring process, and avoiding the cable being damaged or deviating from the wiring track due to friction; by reasonably setting the cable guide wheel, the cable can move more smoothly during the wiring process, improving wiring efficiency, reducing construction time, and improving wiring efficiency.

[0157] The design of the guide roller 34 also effectively supports the cable, reducing the impact of external pressure on the cable, protecting the cable from forces such as squeezing and stretching, and ensuring the safety and reliability of the cable. By providing a smooth surface and appropriate support, the cable guide roller can reduce friction between the cable and other surfaces, reduce cable wear, protect the cable, and extend its service life.

[0158] At the same time, the outer surface of the guide wheel 34 is also provided with a protective layer, which is a rubber layer, used to protect the cable, thereby reducing wear, protecting the cable and improving wiring efficiency.

[0159] Specifically, such as Figure 10 As shown, the cable straightening member 33 includes:

[0160] The mounting plate 331 is symmetrically arranged in the width direction of the display rod 31, and a mounting hole is opened in the length direction of the mounting plate 331;

[0161] Two straightening rollers 332, both ends of the straightening rollers 332 are connected to the mounting holes of the two mounting plates 331 through locking nuts;

[0162] The straightening roller 332 includes a straightening sleeve, bearings connected to both ends of the straightening sleeve, and a connecting shaft connected to the two bearings. Both ends of the connecting shaft are provided with external thread sections, and a protective pad is also provided on the straightening sleeve.

[0163] In the present invention, the distance between the two straightening rollers 332 on the cable straightening member 33 can be adjusted according to specific usage requirements.

[0164] The design of the straightening roller 332 allows the cable to be straightened by adjusting its position and angle. When the cable is bent or twisted, the adjustable roller can apply appropriate force and support to restore the cable to its correct straight position, ensuring accurate and standardized cable routing. The height of the cable can also be flexibly adjusted according to actual needs. The height can be adjusted to suit different routing environments and requirements to meet the cable routing needs of different scenarios.

[0165] Because the straightening roller 332 is designed to reduce cable tension, the cable may be subjected to stretching and tension during the cable laying process, which may cause deformation and damage to the cable. By providing appropriate support and reducing cable curvature, the straightening roller 332 reduces cable tension and stress, ensuring cable safety and reliability. At the same time, it also improves wiring efficiency: By using an adjustable cable straightening roller, the cable can move more smoothly during the wiring process, reducing resistance and friction, improving wiring efficiency, and saving construction time.

[0166] Further, such as Figure 9 As shown, the sliding assembly 4 includes:

[0167] The slide plate 41 is slidably connected to the slide groove 11, and one end of the slide plate 41 is provided with a slide plate limiter connection hole;

[0168] The slide plate locking member 42 is threadedly connected to the slide plate limiter connection hole of the slide plate 41;

[0169] A sliding straightening member 43 connected to the upper surface of the other end of the slide plate 41;

[0170] The sliding straightening member 43 and the cable straightening member 33 have the same shape, structure and size.

[0171] In the present invention, since the cable sliding assembly is provided, on the one hand, the cable can be effectively guided to move along a predetermined path, ensuring that the cable is guided along the correct trajectory during the wiring process, avoiding the cable being damaged or deviating from the wiring track due to friction; on the other hand, the cable tension is relieved. Since the cable may be subjected to a certain amount of tension and stretching during the wiring process, the cable sliding assembly can relieve this tension to a certain extent and protect the cable from being affected by excessive stretching.

[0172] Further, such as Figure 9 As shown, the guide assembly 5 includes:

[0173] The guide connecting seat 51 has guide adjustment holes formed on both side plates of the guide connecting seat 51;

[0174] Two guide rollers 52, both ends of the guide rollers 52 are connected to the corresponding guide adjustment holes through guide locking nuts;

[0175] A first connecting rod 53, one end of which is connected to the guide roller 52 below, and the other end of which is connected to the sliding straightening member 43 below the sliding assembly 4;

[0176] The second connecting rod 54 has one end connected to the guide roller 52 below, and the other end connected to the cable straightening member 33 below the installation opening of the placement rod 31.

[0177] The guide assembly 5 of the present invention provides a predetermined path and channel for guiding cable routing, directing the cables to their intended locations. These guides are typically installed in wiring environments such as walls, floors, ducts, or bridge walls, ensuring that cables are routed along the correct path, preventing them from becoming misplaced or misplaced. They also help organize wiring spaces, making them neater and more standardized. They can conceal cables within walls, floors, or other structures, reducing clutter and improving space utilization.

[0178] The guide components of the present invention can protect the cables from collision, pressure or damage from external objects. They can provide a physical barrier to protect the cables from damage and wear, extending the service life of the cables.

[0179] The guide assembly of the utility model can also help manage the arrangement of cables to make them neat and orderly. By using the guide assembly, multiple cables can be fixed together and maintained at a certain distance to avoid entanglement and interlacing, which is convenient for maintenance and management.

[0180] In the present invention, the guide roller 52 and the straightening roller 332 have the same shape and structure; the total number of the first connecting rod 53 and the second connecting rod 54 are both two.

[0181] Both ends of the straightening roller 332 are connected to the mounting holes of the two mounting plates 331 through locking nuts; wherein, the straightening roller 332 includes a straightening sleeve and bearings connected to both ends of the straightening sleeve and a connecting shaft connected to the two bearings, both ends of the connecting shaft are provided with external threaded sections, and a protective pad is also provided on the straightening sleeve.

[0182] Before using the above-mentioned adjustable auxiliary device for laying cables on a bridge, the already manufactured device needs to be installed as a backup.

[0183] After the lifting device 31 is lifted up, the lifting rod 31 and the extension rod 32 are tightened and the lifting device 32 is tightened, thereby fixing the lifting device 31 and the extension rod 32 to the outer wall of the bridge.

[0184] Then, after the installation is completed, the operator only needs to install the winding drum 7 on the placement bracket 21 through the placement openings coaxially opened on both sides of the placement bracket 21. In order to fix it firmly, the placement openings can be fixed with locking pieces, or a removable installation shaft can be provided on the placement bracket 21, and the hollow hole of the winding drum 7 is passed through the installation shaft and placed on the placement bracket 21. Then, the two ends of the installation shaft are fixed;

[0185] Finally, according to the needs of wiring, the operator adjusts the sliding assembly 4 so that the slide 41 slides to the corresponding position in the slide groove 11, thereby fixing the sliding straightening member 43 in the appropriate position. At the same time, the guide assembly 5 is also adjusted to the appropriate position. After the adjustment is completed, cable wiring or laying work can be carried out.

[0186] When laying the cable, tear open the outer packaging of the cable reel, pull out part of the cable 8, lead out the free end of the cable 8 from the winding reel 7, pass the head of the cable 8 through the sliding straightening part 43 area, and leave a part of the cable 8. After that, adjust and fix the cable straightening part 33 on the sliding straightening part 43, it is convenient to carry out the initial pulling and straightening of the cable 8, and then pass the cable 8 through the guide roller 52 on the guide assembly 5 and the cable straightening part 33 on the cable straightening mechanism 3 in turn, and at the same time, adjust the straightening roller 332.

[0187] When adjusting and fixing the cable straightening mechanism 3, since each set of cable straightening parts 33 is composed of two identical straightening rollers 332, the roller shaft can move in the slide groove, driving the straightening rollers 332 to move to a suitable position, and clamping the cable 8 between the two straightening rollers 332. During operation, the lower straightening roller 332 can be moved and adjusted first. After it is moved to the appropriate position, the fastening bolts 45 at both ends of the lower straightening roller 332 are wound around the threaded screw at the end of the rolling shaft 43 and tightened until they are tightly against the support plate 41 to fix the position; then the upper straightening roller 332 is slid to adapt to the diameter of the cable 8, and the fastening bolts at both ends of the upper straightening roller 332 are wound around the threaded screw on the rolling shaft and tightened until they are tightly against the support plate, thereby fixing the straightening roller 332 and preventing it from moving.

[0188] After the cable straightening mechanism 3 is adjusted and fixed, the head of the cable 8 is pulled forward to drive the cable 8 behind it to come out of the winding drum 7 and then pass through the sliding component 4 and the guide component 5 in sequence, and finally pulled forward along the cable straightening mechanism 3 to achieve the cable traction straightening effect.

[0189] According to the straightening requirements, multiple groups of straightening rollers 332 can be provided to enhance the straightening effect on the cable.

[0190] In addition, according to the height requirement of traction and straightening laying, the guiding and straightening of the traction direction of the cable 8 can be carried out by adjusting the height of the fixed positions of multiple groups of straightening rollers 332.

[0191] Finally, as time goes by, when the laying work of all the cables 8 is completed, the operator only needs to first wind the remaining cable 8 onto the winding disc 7 for storage again. Finally, the cable straightening mechanism 3 is lowered and separated from the outer wall of the bridge through the handrail 37. At the same time, the telescopic rod 32 is adjusted and retracted into the placing rod 31, and the tightening lock 6 is used for tightening again. Subsequently, after cleaning and repairing each component, the operator moves the present utility model to the designated tool storage warehouse for storage to be used for the next cycle of turnover.

[0192] Embodiment 2

[0193] As Figures 11 to 13 shown, this Embodiment 2 is the same as Embodiment 1, and the only difference is that it further includes a counterweight device 9, and the counterweight device 9 is arranged below the base 1 near the end of the cable placing rack 2;

[0194] The counterweight device 9 includes:

[0195] A mounting seat 91, and two end openings of the mounting seat 91 are symmetrically threadedly connected with fastening members 92;

[0196] A counterweight rack 93, which is slidably installed in the mounting seat 91, and one end of the counterweight rack 93 is provided with a handle 94;

[0197] Wherein, a fixed ring 95 is further fixedly connected to the mounting seat 91 at the end of the fastening member 92, and the fastening member 92 is connected to the fixed ring 95 through a rope.

[0198] In the present utility model, the mounting seat 91 is integrally in a U-shaped structure, the cross-section of the mounting seat 91 is L-shaped, and the mounting seat 91 is made of L-shaped angle steel by welding.

[0199] The configuration rack 93 is a fence structure, or a hollow guardrail structure, or a square frame body.

[0200] A protective sleeve that fits with the handle 94 is further sleeved on the handle 94. The protective sleeve is a rubber sleeve, and several rubber protective protrusions with a连体结构 (should be "connected structure") are provided on the outer surface of the rubber sleeve. The rubber protective protrusions are granular or annular protrusions. Therefore, since a protective sleeve is sleeved on the hand-held part of the hand-held operating rod 41, it can protect the operator's hand from being worn due to long-term work during long-term work, ensuring the safety of construction.

[0201] The specific installation and use of this embodiment 2 is the same as that of embodiment 1. The only difference is that during the laying process, as the cable laying time goes by, when there is not much cable 8 left on the winding drum 7, and the operator is worried that the utility model will tilt forward due to gravity, the operator only needs to first loosen and remove the tightening member 92, and then use the handle 94 to pull out the counterweight device 9 set at the lower rear of the base 1, so that the counterweight frame 93 extends outward, so that the counterweight frame 93 can achieve balanced weight, provide appropriate counterweight, avoid the device from tilting forward or tipping over, balance the weight of the lifted object, and ensure that the crane maintains a balanced state during operation; it can reduce the force on the cable auxiliary laying device itself, reduce its load, extend the service life of the mechanical equipment, reduce maintenance costs, make the cable auxiliary laying device more stable, reduce swing and vibration, reduce swing caused by wind or other external factors, ensure safe and reliable lifting operations, and improve the accuracy and efficiency of operations.

[0202] Other specific implementations are the same as those in Example 1 and will not be repeated here.

[0205] In the present invention, the mobile device 12 is a fixed wheel or a universal wheel. Therefore, due to the provision of the mobile device 12, it is easy to move, flexible in transport and transportation, and reduces the manual labor of the operator. The brake device is provided on the mobile wheel to increase safety and better fix the device.

[0206] The specific installation and use of Example 3 are the same as those of Example 1 and Example 2. The only difference is that during use, the operator only needs to move the utility model to the designated working position through the moving devices 12 set at the four corners of the base 1 according to actual needs, and realize the moving or braking state by turning on or off the brake device on the moving device 12.

[0207] Other specific implementations are the same as those in Example 1 and Example 2 and will not be repeated here.
