Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to auxiliary equipment for laying bridge cables. Background Art

[0002] Cable is a wire product made of one or more mutually insulated conductors wrapped with insulation and protective layers, used to transmit electrical energy, signals or realize electromagnetic energy conversion. When laying cables, they need to be installed in cable trays, which provide stable support for cables so that they can be laid in an orderly manner on a certain path to prevent them from hanging or scattering randomly. When the cables are moved in the trays through traction mechanisms, guide mechanisms need to be set at the corners of the trays, so that the cables can move along the track of the trays and avoid being scratched by the trays. When the cables are moving, if the resistance to the movement of the cables at the rear increases, causing their moving speed to decrease, and the traction mechanism drives the cables in front When the cable is still moving at the original speed, the corners of the cable will be subjected to a strong pulling force, which will reduce the bending arc and curvature radius of the cable, and cause the cable to be subjected to greater bending stress, resulting in deformation of the internal conductor, rupture of the insulation layer and other damage, seriously affecting the electrical performance and service life of the cable. The existing guiding mechanism has a relatively single function and cannot timely and effectively adjust the bending state of the cable when the cable is subjected to greater bending stress to reduce the damage to the cable. It also cannot adaptively change the bending state of the cable according to changes in the cable movement speed and the tension it is subjected to, thereby failing to effectively protect the cable from damage caused by excessive bending and pulling.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, 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 accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1-Figure 7 , which is the first embodiment of the present invention, provides a bridge cable laying auxiliary device, and the bridge cable laying auxiliary device includes a cable bridge 101.

[0033] The cable tray 101 is used to provide stable support for the cables so that they can be laid in an orderly manner along a certain path to prevent the cables from being hung or scattered randomly.

[0034] The guide assembly 200 includes a guide wheel 201a, a support frame 201b, a positioning shaft 201c, a connecting block 201d, a rotating column 201e and a fixed shaft 201f. The guide wheel 201a is arranged above the cable tray 101, the support frame 201b is located at one side of the guide wheel 201a, one end of the positioning shaft 201c is fixed to the guide wheel 201a, the connecting block 201d is fixed to one side of the support frame 201b, the rotating column 201e is located in the connecting block 201d, the fixed shaft 201f is fixed in the connecting block 201d, a spiral groove 201e-1 is opened on the rotating column 201e, the fixed shaft 201f slides in the spiral groove 201e-1, the support frame 201b is opened with a positioning groove 201b-1, and the positioning shaft 201c slides in the positioning groove 201b-1.

[0035] There are two groups of guide assemblies 200, both located at the corners of the cable tray 101. Through the cooperation of the support frame 201b and the positioning shaft 201c, they are used to support and position the guide wheel 201a. Through the setting of the guide wheel 201a, it is used to support and position the cables at the corners of the cable tray 101 to avoid displacement during movement.

[0036] The two guide wheels 201a are close to each other in the initial state. At this time, when the cable passes through the corner of the cable tray 101, the bending arc of the cable is small and the curvature radius is low. The cable can move smoothly in this state and occupies relatively small space. During the movement of the cable, it will not cause obstruction to other cables and can prevent the cable from being excessively loose.

[0037] The two spiral grooves 201e-1 are respectively located at the two ends of the rotating column 201e, and the threads of the two spiral grooves 201e-1 are set in opposite directions. When the rotating column 201e rotates, the fixed shaft 201f will slide in the spiral groove 201e-1, thereby driving the connecting block 201d to move through the fixed shaft 201f, and driving the support frame 201b and the guide wheel 201a to move through the connecting block 201d, so that the distance between the two guide wheels 201a becomes larger, thereby increasing the bending curvature of the cable and increasing the curvature radius of the cable.

[0038] The adjustment assembly 300 is arranged on the guide assembly 200, and includes a rotating rod 301a, a connecting rod 301b, a connecting sleeve 301c, a fixed rod 301d, a connecting shaft 301e, a fixing block 301f, a supporting block 301g and a first spring 301h. The rotating rod 301a is fixed to the outside of the rotating column 201e, the connecting rod 301b is rotatably connected to the outside of the positioning shaft 201c through a bearing, and the connecting sleeve 301c is sleeved on the connecting rod 301b. On the outside, one end of the fixed rod 301d is fixed to the connecting sleeve 301c, the connecting shaft 301e is fixed in the fixed rod 301d, a sliding groove 301a-1 is opened on the rotating rod 301a, the connecting shaft 301e slides in the sliding groove 301a-1, the fixed block 301f is fixed to the top of the support frame 201b, the support block 301g is located on one side of the positioning shaft 201c, and the two ends of the first spring 301h are respectively fixed to the support block 301g and the fixed block 301f.

[0039] The number of the adjusting components 300 corresponds to that of the guiding components 200. The rotating rod 301a is inclined, and the connecting rod 301b is movably connected to the connecting sleeve 301c.

[0040] The support block 301g is supported by the first spring 301h, and the positioning shaft 201c and the guide wheel 201a are supported and positioned by the support block 301g, so that the guide wheel 201a is always located at the initial position.

[0041] When the cable is subjected to a large pulling force during movement and the cable at the rear cannot continue to move forward, the corners of the cable will be subjected to greater bending stress, causing the bending arc of the cable to become smaller. At the same time, the cable will push the guide wheel 201a to move, and the guide wheel 201a pushes the support block 301g to move through the positioning shaft 201c, so that the support block 301g squeezes the first spring 301h, so that the cable can be buffered by the first spring 301h, dispersing the instantaneous impact force, reducing the structural damage caused by sudden bending stress at the cable corners, and protecting the conductor and insulation layer inside the cable.

[0042] When the positioning shaft 201c moves, it will drive the connecting rod 301b and the connecting sleeve 301c to move, and through the connecting sleeve 301c, it will drive the fixing rod 301d and the connecting shaft 301e to move, so that the connecting shaft 301e can slide in the slide groove 301a-1. Through the cooperation of the two, the rotating rod 301a can be driven to rotate, and the rotating column 201e can be driven to rotate through the rotating rod 301a, so that the two guide wheels 201a can move away from each other, and increase the bending curvature and curvature radius of the cable to reduce the bending stress of the cable, thereby avoiding excessive bending of the cable that may cause deformation of the internal conductor, rupture of the insulation layer and other damages.

[0043] When the additional tension on the cable disappears, the first spring 301h can push the support block 301g to move, so that the support block 301g pushes the positioning shaft 201c and the guide wheel 201a to reset. At the same time, the rotating rod 301a will drive the rotating column 201e to rotate in the opposite direction, so that the two guide wheels 201a can be moved to the initial position and the bending curvature of the cable can be restored to its initial state, thereby avoiding the cable occupying a large space when moving and the cable becoming excessively loose after laying.

[0044] The trigger assembly 400 is arranged on the guide assembly 200, and includes a gear 401a, a tooth plate 401b, a connecting column 401c, a fixed sleeve 401d, a movable column 401e, a connecting plate 401f, a plug rod 401g and a sensing ball 401h. The gear 401a is arranged on the top of the positioning shaft 201c, the tooth plate 401b is fixed to the top of the fixed block 301f, the tooth plate 401b is meshed with the gear 401a, the connecting column 401c is fixed to the top of the positioning shaft 201c, the fixed sleeve 401d is fixed to the outside of the connecting column 401c, the movable column 401e is inserted into the fixed sleeve 401d, the connecting plate 401f is fixed to one end of the movable column 401e, the plug rod 401g is fixed to one side of the connecting plate 401f, the sensing ball 401h is located in the fixed sleeve 401d, and the gear 401a is provided with a hole 401a-1 corresponding to the plug rod 401g.

[0045] The number of trigger components 400 corresponds to the guide components 200. When the cable moves fast, it has a larger inertia. The smaller bending arc and curvature radius of the cable will cause the cable to turn more quickly at the corner, and the friction will be concentrated in a smaller area, resulting in increased wear of the cable sheath and even damage to the internal structure. It is also easy to cause excessive bending and deformation of the cable, which will affect the arrangement of its internal conductors and the uniformity of the insulation layer.

[0046] Since the cable fits the guide wheel 201a, the cable will drive the guide wheel 201a to rotate when it moves, and the guide wheel 201a will drive the positioning shaft 201c and the connecting column 401c to rotate. When the cable moves too fast and causes the connecting column 401c to rotate too fast, the rotation of the connecting column 401c will generate a large centrifugal force. Under the action of the large centrifugal force, the induction ball 401h will push the movable column 401e to move, and drive the connecting plate 401f and the plug rod 401g to move through the movable column 401e, so that the plug rod 401g is inserted into the socket 401a-1, so that the The connecting column 401c is connected to the gear 401a and drives the gear 401a to rotate. When the gear 401a rotates, it will move along the tooth plate 401b, thereby driving the positioning shaft 201c to move, and then the connecting rod 301b and the connecting sleeve 301c can be driven to move through the positioning shaft 201c, so that the rotating column 201e can rotate and the distance between the two guide wheels 201a can be increased, thereby increasing the bending arc and curvature radius of the cable, so that the cable can turn more smoothly, reduce the adverse effects of inertia, and disperse the friction of the cable, thereby reducing the wear of the cable.

[0047] Example 2

[0048] Reference Figure 1-Figure 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0049] Specifically, the outer side of the rotating column 201e is rotatably connected to the support plate 202a through a bearing, a stabilizing block 202b is fixed to one side of the support plate 202a, and a stabilizing frame 202c is fixed to one side of the stabilizing block 202b.

[0050] There are two stabilizing blocks 202b and two stabilizing frames 202c, which are located on both sides of the support plate 202a and are arranged at right angles. The support plate 202a is used to support the rotating column 201e. The stabilizing blocks 202b and the stabilizing frames 202c are used to support the support plate 202a and connect the guide assembly 200 with the cable tray 101.

[0051] Specifically, the stabilizing frame 202c is clamped on the top of the cable tray 101 and is locked and fixed to the cable tray 101 by bolts.

[0053] When the sensing ball 401h moves, it will push the force plate 402 to move, so that the movable column 401e can be driven to move through the force plate 402. When the cable moves slower, the centrifugal force generated by the connecting column 401c is reduced, and the force plate 402 can be pushed to move by the second spring 403, and the movable column 401e and the connecting plate 401f can be driven to move through the force plate 402, and the insertion rod 401g can be separated from the socket 401a-1, so that the connecting column 401c can be separated from the gear 401a, and then under the action of the first spring 301h, the positioning shaft 201c and the guide wheel 201a can be reset.

[0054] Specifically, a stabilizing column 203 is fixed to one side of the support plate 202a, and the stabilizing column 203 is movably connected to the connection block 201d.

[0055] The stabilizing column 203 is used to position the connecting block 201d to prevent it from being offset during movement.

[0056] Specifically, a positioning column 302 is fixed to one side of the support block 301g, and the positioning column 302 is movably connected to the fixing block 301f.

[0057] The support block 301g is positioned by the positioning column 302 to make its movement more stable.

[0058] Example 3

[0059] Reference Figure 1-Figure 7 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0060] Specifically, there are multiple jacks 401a-1, which are evenly distributed in a ring shape on the inner side of the gear 401a.

[0061] By providing a plurality of insertion holes 401a-1, the insertion rod 401g can be inserted into the insertion hole 401a-1 when it is rotated to any angle.

[0062] Specifically, a stabilizing sleeve 404 is fixed to the bottom of the gear 401 a , a positioning sleeve 405 is fixed to the top of the positioning shaft 201 c , and the stabilizing sleeve 404 is rotatably connected to the positioning sleeve 405 via a bearing.

[0063] The gear 401 a is connected to the positioning shaft 201 c through the cooperation of the stabilizing sleeve 404 and the positioning sleeve 405 .

[0064] Specifically, the connecting plate 401f is arc-shaped and can fit with the inner side of the gear 401a.

[0065] Specifically, the sensing ball 401 h has its own weight and is in contact with the force-bearing plate 402 .

[0066] In summary, the bridge cable laying auxiliary equipment of the present invention has the following advantages:

[0067] 1. When the cable is subjected to greater bending stress, the bending arc and curvature radius of the cable can be increased in time to avoid damage caused by excessive bending of the cable;

[0068] 2. When the cable moves too fast, resulting in excessive inertia and friction, the bending arc and curvature radius of the cable can be increased in time to make the cable turn more smoothly and disperse the friction of the cable;

[0069] 3. The bending arc and curvature radius of the cable can be adaptively increased or decreased under different cable conditions, so that the cable can move more stably;

[0070] 4. When the cable corners are subjected to large bending stress, the cables can be buffered to disperse the instantaneous impact force and reduce the structural damage caused by sudden bending stress at the cable corners;

[0071] Fifth, the impact force acting on the cable tray 101 can be buffered to avoid the situation where the cable tray 101 is damaged due to the impact on the cable.

[0072] During use, when the cable is subjected to a large pulling force during movement and the cable at the rear cannot continue to move forward, the corners of the cable will be subjected to greater bending stress, causing the bending arc of the cable to become smaller. At the same time, the cable will push the guide wheel 201a to move, and the guide wheel 201a will drive the positioning shaft 201c to move. When the positioning shaft 201c moves, it will drive the connecting rod 301b and the connecting sleeve 301c to move, and drive the fixing rod 301d and the connecting shaft 301e to move through the connecting sleeve 301c, so that the connecting shaft 301e slides in the slide groove 301a-1. Through the cooperation of the two, the rotating rod 301a can be driven to rotate, and the rotating column 201e can be driven to rotate through the rotating rod 301a, so that the two guide wheels 201a can move away from each other, and the bending arc and curvature radius of the cable can be increased to reduce the bending stress of the cable, thereby avoiding excessive bending of the cable that can cause deformation of the internal conductor, rupture of the insulation layer and other damage.

[0073] When the additional tension on the cable disappears, the first spring 301h can push the support block 301g to move, so that the support block 301g pushes the positioning shaft 201c and the guide wheel 201a to reset. At the same time, the rotating rod 301a will drive the rotating column 201e to rotate in the opposite direction, so that the two guide wheels 201a can be moved to the initial position and the bending curvature of the cable can be restored to its initial state, thereby avoiding the cable occupying a large space when moving and the cable becoming excessively loose after laying.

[0074] When the cable moves too fast and causes the connecting column 401c to rotate too fast, the rotation of the connecting column 401c will generate a large centrifugal force. Under the action of the large centrifugal force, the induction ball 401h will push the movable column 401e to move, and through the movable column 401e, the connecting plate 401f and the plug rod 401g will move, so that the plug rod 401g is inserted into the socket 401a-1, so that the connecting column 401c can be connected to the gear 401a, and the gear 401a can be driven to rotate. When the gear 401a rotates, it will move along the tooth plate 401b, thereby driving the positioning shaft 201c to move, and then the connecting rod 301b and the connecting sleeve 301c can be driven to move through the positioning shaft 201c, so that the rotating column 201e can be rotated, and the distance between the two guide wheels 201a can be increased, thereby increasing the bending curvature and curvature radius of the cable, so that the cable can turn more smoothly, reduce the adverse effects of inertia, and disperse the friction of the cable, thereby reducing the wear of the cable.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
