[0002] With the development of society and the improvement of people's living standards, cables are used everywhere in people's lives. However, during the laying or erecting process, or in the process of dragging the cables from the cable drum for use, a cable support frame is generally used to fix the position where the cables pass. However, the cable support frame is generally a fixed structure, and the position of the support frame must be moved when the cables are moved or dragged. For a support frame using a pulley, after the cables are pulled out of the cable drum, or during the laying / erecting process, the cables are not straight, but have a certain curvature, which easily leads to instability of the support frame. Based on the above problems, designing a wire arrangement and passing device that can allow cables to pass through and will not be affected by the curvature and offset of the cables has become a problem that needs to be solved urgently.

[0018] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.

[0019] The utility model relates to a wire material arrangement and passing device, which comprises a passing frame body 1, a guide wheel 2 and a lifting wheel 3. The lifting wheels 3 are arranged in pairs and are rotatably mounted on two opposite ends of the passing frame body 1. The circumferential rolling surfaces of the lifting wheels 3 protrude from the top end surface of the passing frame body 1 to form a roller group for the wire material to pass through. The guide wheel 2 is arranged at the interval between the two lifting wheels 3 and is rotatably mounted on the passing frame body 1. The guide wheels 2 are arranged in pairs, and the circumferential rolling surfaces are inclined to the top end surface of the passing frame body 1. The adjacent guide wheels 2 are arranged in opposite inclination directions to form a "V"-shaped rolling passing channel for the wire material to pass through. When in use, the lifting wheels at both ends can prevent the cables from being scratched by the edges of the through-frame body 1 on both sides when passing through the device of the utility model, causing damage to the cables, and the lifting wheels 3 can be rotated to reduce the friction between the cables and the through-frame body, so as to facilitate the passage of the cables. The lifting wheels 3 on both sides of the channel are also higher than the upper end surface of the through-frame 1. On the one hand, the cables can be kept away from the through-frame body 1 to achieve the function of lifting the cables. On the other hand, the lifting wheels 3 have a low passage resistance to the cables, so that the most basic cable passage path can be formed during use. However, during use, although the lifting wheels 3 can reduce the passage resistance and form a simple cable passage path, the cables are not necessarily in a completely straight state when passing through. If the cables have a curved arc, they are prone to left and right deviations when passing through. The cable is caused to deviate from the cable passage path. This problem can be solved by setting a guide wheel 2. Specifically, when in use, the guide wheel 2 is tilted to realize the side wall function of the cable passage path. The cable first enters the cable passage path through the lifting wheel at one end. The paired guide wheels 2 are tilted to position the cable at the position of the passage path. For example, the cable enters the cable passage path from the lifting wheel 3 in an arc-shaped tortuous state, and then the curved part with an arc gradually moves away from the cable passage path during the offset process. In this process, the tilted guide wheel 2 will block the cable. The adjacent guide wheel 3 misaligned position can have a buffer space in the relative direction after the cable is blocked by the guide wheel 2. Compared with the use of a groove structure, this utility model patent can keep the cable from slipping out of the passage path through the staggered guide wheels 2. The device of the utility model can be used on a support frame. The height of the support frame can lift the device and the cable off the ground to play the role of a passing device or a wire seat. The support frame can be a triangular bracket or other platform with an installation plane that can be purchased on the market, so the support frame is not described in detail in this application.

[0020] In order to further enhance the buffering effect on the cable, the guide wheel 2 includes a guide roller 21, an axial mounting member 22, a torsion spring 23 and a rotating shaft connecting member 24. One end of the rotating shaft connecting member 24 is a rotating shaft capable of rotatably mounting the guide roller 21, and the other end along the length extension direction of the rotating shaft is provided with a through hole. The rotating shaft connecting member 24 is connected to the axial mounting member 22 through the through hole. The torsion spring 23 is sleeved on the rotating shaft connecting member 24 and the two ends are respectively clamped with the rotating shaft connecting member 24 and the end of the axial mounting member 22, forming a buffering adjustment mechanism in which the rotating shaft connecting member 24 can deflect circumferentially along the axial mounting member 22 and can return to its original position. When in use, the guide wheel 2 can generate a corresponding tilt angle according to the arc or bending degree of the cable, and realize the function of automatic adjustment according to the wire. Specifically, the guide roller 21 can be rotatably mounted on the shaft connector 24. First, it can ensure that the guide roller 21 rotates itself to reduce the friction in the process of contacting the cable. The other end of the shaft connector 24 can rotate around the shaft connector 22 through the shaft connector 22, and at the same time drive the belt guide roller to work together. Because the shaft connector 22 is fixedly connected to the frame, a torsion spring 23 is set on the shaft connector 24. The guide roller 22 can complete the reset function. Specifically, when the cable is working, after the lifting wheel 3 enters the cable passage path, the staggered guide rollers 21 will limit the range of left and right movement of the cable, so that it can be stuck in the "V"-shaped passage path to prevent deviation. When the larger arc portion of the cable itself is in the passage path, the guide wheel 2 can have more offset under the action of the torsion spring 23. After the larger arc portion passes, the torsion spring 23 resets and drives the guide roller 21 back to the initial state, and continues to resist the cable passing;

[0021] However, it is difficult to achieve this effect if a "V"-groove roller is used, because the amount of cable deflection during the passage process can only be fixed to the spacing of the "V"-groove opening, and it is impossible to make adaptive adjustments to the actual situation of the cable; and the staggered arrangement of the guide wheels 2 can have a larger offset margin on the side where the guide wheel is not set at the position of a single guide wheel, so that it can be restricted by the guide wheel 2 on the cable passage path, and at the same time have sufficient offset freedom, thereby improving the cable's passing performance on the device of the utility model.

[0022] The guide roller 21 is tapered, and the diameter of the guide roller 21 is tapered from one end of the through hole provided on the rotating shaft connecting member 24 to the other end. Since the direction of the arc bending of the cable is uncertain, when bending occurs in the up and down directions, the curved part passes through the cable passing path and returns to the normal straight state. The tapered guide wheel can facilitate the cable to return to the cable passing path formed by the guide wheel 2 after falling, so that the cable can more easily enter the set cable passing path.

[0023] The frame body 1 includes an end connecting frame 11 and a middle mounting frame 12. The number of the end connecting frames 11 is 2, and they are fixedly mounted on the opposite sides of the middle mounting frame 12. The top and bottom surfaces of the end connecting frames 11 and the middle mounting frame 12 are both hollow structures. In order to facilitate disassembly and storage, provide a portable function, and be able to be installed whenever needed, a detachable split-structure frame body 1 is used. The middle mounting frame 12 can be installed with a fixed connection point between or other parts to play the role of positioning the frame body 1. The connecting frames 11 at both ends are then installed to ensure its balanced performance when subjected to force. When the top and bottom directions are hollowed out, stains on the surface of the cable that are easy to fall off are easy to fall on the frame body 1 under the wheel pressure of the lifting wheel 3 and the guide wheel 2. Setting a hollow structure that is transparent from top to bottom can avoid this problem and make it fall to the ground naturally.

[0024] The end coupling frame 11 includes side walls 111 and connecting baffles 112. The side walls 111 are arranged in pairs and fixedly connected by the connecting baffles 112 to form a frame-like frame body with hollow top and bottom surfaces. The lifting wheel 3 is fixedly connected to the side walls 111 on both sides through the two ends of the rotating shaft. The guide wheel 2 can be rotatably installed on the connecting baffle 102, and the roller rotation direction of the guide wheel 2 is set in the same direction as the rotation and feeding direction of the lifting wheel 3. Through this arrangement, the position of the lifting wheel 3 installed on the coupling frame 11 can be ensured to be on the center line of the cable passing path, and the axial mounting member of the guide wheel 2 can also be set on the center line of the coupling frame 11 through the connecting baffle 112, so that the "V"-shaped cable passing path formed by the guide wheel 2 can be ensured to be a straight line along the center line.

[0025] The inner wall of the side of the middle mounting frame 12 is movably connected with a limit adjustment member 4, which includes a limit bending rod 41, an inflection point bearing 42, a connecting ring 43 and a limit contact head 44. The limit bending rod 41 has an angle bend in the middle, and the outer ring of the inflection point bearing 42 is fixedly connected to the limit bending rod 41 at the angle bend. The inner ring can be rotatably installed on the inner wall of the middle mounting frame 12, and the protruding end of the limit bending rod 41 at the bend faces the inner wall surface of the middle mounting frame 12, forming a swing arm structure with the inflection point bearing 42 as the rotation point. The limit contact head 44 and the connecting ring 43 are respectively fixedly connected to the ends of the limit bending rod 41 facing the top and bottom directions. The limit adjustment members 4 are arranged in pairs and are respectively installed on the opposite inner walls of the middle mounting frame 12. The opposite pair of limit adjustment members 4 are staggered to form a continuous staggered limit structure. When in use, one end of the connecting ring 43 of the limit adjustment member 4 can be connected to a traction rope or other structure that can adjust the relative distance between a pair of connecting rings 43, so that their relative distance can be close to each other but cannot be separated. Through the curved rod of the seesaw structure, the limit contact head can press against the cable from the opposite side, that is, if the curved rod is set on the left, its limit contact head contacts the cable on the right side of the cable, rather than on the same side of the installation position. In this way, the limit contact heads of the paired limit adjustment members will also form a "V"-shaped cable passing path, but due to the distance between the two connecting rings 43 at the lower ends, the "V"-shaped path between the limit contact heads 44 will be able to narrow, but cannot expand outward and widen, thus forming a limiting structure for the left and right offset of the cable, thereby compensating for the fact that the guide wheel can press against the cable at the position of the outer walls on both sides, but cannot limit the degree of its left and right offset, thereby improving the reliability of the device when in use.

[0026] The limit contact head 44 includes a contact roller 441 and a fixed frame 442. The fixed frame 442 is fixedly connected to the end of the limit bent rod 41. The contact roller 441 is rotatably installed in the frame of the fixed frame 442 to form a driven roller structure that can generate rolling friction when in contact with the wire. In order to ensure that when the cable passes through, after the displacement reaches the maximum amount and has contacted the limit contact head, it will rub against the cable. The limit contact head 44 uses the contact roller 441 to reduce the friction with the cable, and will not cause damage to the cable when the cable passes. The fixed frame 442 is used to install the roller because the limit contact head 44 needs to limit the maximum displacement of the cable. When the cable has reached the maximum limit, the contact head needs to resist the trend of the cable continuing to deviate. The use of a frame wheel group structure can improve the firmness of the contact head position.

[0027] The limit bent rod 41 has a through hole at the angle bend in the middle part, and the inflection point bearing 42 is embedded in the through hole and fixedly connected to the inner wall of the through hole. The limit bent rod 41 used as a limiter is in a stress state when realizing the limit function of the cable. The central axis structure is used to directly set a through hole at the position of the bent rod 41 and install the inflection point bearing in the through hole, so that the bent rod and the inflection point bearing can form a whole. If the external joint structure is used, the stress point is single, and the connection position of the bearing and the bent rod is fatigued, resulting in a shortened service life of the device.

[0028] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
