Description

Technical Field

[0001] The present invention belongs to the technical field of cable installation, and in particular relates to a roller-type cable bearing frame and an application method thereof. Background Art

[0002] A cable bearing frame is a bracket specially used to support and guide cables. Rollers are set on the bearing frame. Cables are supported by rollers, which is a roller bearing frame. The cable can slide on the rollers through the rotation of the rollers. When the cable is blown by wind and thermal expansion and contraction, the cable will move relative to the axial direction of the cable. The support of the roller bearing frame can make the cable slide axially while being supported.

[0003] The existing bearing-type cable bearing frame is fixed on a wall or a bridge or tower. However, due to the limitations of the fixed position of the bearing frame, the cable may turn or one end may swing at the cable support position. Although some existing bearing frames have the function of adjusting the cable support angle, it is difficult to dynamically support the cable in the turning or swinging state, so that the cable may separate from the roller when the cable swings horizontally or the cables on both sides of the bearing frame are bent. Summary of the Invention

[0004] The present invention provides a roller-type cable bearing frame and an application method thereof, which are used to solve the problem in the prior art that bearing-type cable bearing frames are difficult to dynamically support cables that are performing lateral swings and lateral turns.

[0005] The technical solutions of the present invention are as follows:

[0006] A roller-type cable bearing frame comprises a fixed bracket, a bearing bracket, a first roller, an angle adjustment mechanism and a deflection mechanism. The fixed bracket is fixedly mounted on a bridge frame or a tower frame. The bearing bracket is rotatably connected to an end of the fixed bracket away from the bridge frame. The first roller is rotatably connected to the bearing bracket. The angle adjustment mechanism is arranged on the fixed bracket and an end of the bearing bracket away from the first roller. The angle adjustment mechanism is used to fix the rotation angle of the bearing bracket on the fixed bracket. The deflection mechanism is rotatably connected to an end of the bearing bracket close to the angle adjustment mechanism. The deflection mechanism includes a second roller. The first roller and the second roller jointly support the cable. The deflection mechanism is used to adjust the lateral deflection angle of the cable when supporting the cable.

[0007] One end of the fixing bracket close to the bearing bracket is arranged in an inclined shape. When the bearing bracket is rotated to be parallel to the fixing bracket, the bearing bracket is located on one side of the fixing bracket.

[0008] The angle adjustment mechanism includes a locking plate, a fixing hole, a slide cylinder and a docking pin, and two locking plates are provided. The two locking plates are fixedly connected to the bearing bracket, and the two locking plates are respectively arranged on the upper and lower sides of the fixing bracket. A plurality of fixing holes are provided, and a plurality of fixing holes are circumferentially opened on the locking plate. The slide cylinder is fixedly connected to the fixing bracket, and the slide cylinder is arranged between the two locking plates. A groove is opened on the side of the slide cylinder, and two docking pins are provided. The two docking pins are arranged in the slide cylinder to slide in opposite directions. A spring is provided between the two docking pins, and the two docking pins can slide out of the slide cylinder and then extend into the fixing hole.

[0009] The bearing bracket is fixedly connected to a first rotating shaft and a second rotating shaft. The fixed bracket is rotatably connected to the first rotating shaft. The deflection mechanism is rotatably connected to the second rotating shaft. The first rotating shaft is located at the center of the locking plate.

[0010] The deflection mechanism also includes a deflection bracket and a support rod. The deflection bracket is rotatably connected to the second rotating shaft. The second roller is rotatably connected to the end of the deflection bracket away from the second rotating shaft. The support rod is rotatably connected to the deflection bracket. The end of the support rod away from the deflection bracket is detachably connected to the fixing hole.

[0011] A clamping ring is rotatably provided on the bearing bracket, and the clamping ring is arranged in the center of the locking plate on the upper side. When the deflection bracket is parallel to the bearing bracket, the clamping ring is located in the center of the roller one and the roller two. The clamping ring is arranged in a C shape, and the clamping ring is made of elastic material. The cable passes through the center of the clamping ring with the support of the roller one and the roller two.

[0012] The roller 1 and the roller 2 are respectively rotatably connected to the bearing bracket and the deflection bracket on one side close to the clamping ring, and the docking pin and the support rod can be detachably connected to the fixing holes on both sides of the bearing bracket.

[0013] A method for applying a roller-type cable bearing frame, using the above-mentioned roller-type cable bearing frame, includes the following steps:

[0014] Step 1: Angle adjustment: squeeze the two docking pins at the same time. The springs are compressed and shortened, and the two docking pins are separated from the fixing holes on the two locking plates. After rotating the bearing bracket to the required angle, release the docking pins.

[0015] Step 2: Deflection adjustment: Disconnect the support rod from the fixing hole, rotate the deflection bracket to the required angle, and then connect the support rod to the fixing hole;

[0016] Step 3: Fix the cable: Place the cable on roller 1 and roller 2, and pass the cable through the clamping ring;

[0017] Step 4: Support the cable: When the cable is pulled in the axial direction, the cable slides on roller one and roller two, driving roller one and roller two to rotate.

[0018] The working principle and beneficial effects of the present invention are:

[0019] 1. In the present invention, by providing a bearing bracket, the bearing bracket is rotatably arranged on the fixed bracket, so that the cable can be supported at various angles. At the same time, by providing a deflection mechanism on the bearing bracket, the rollers 1 and 2 can be deflected at a certain angle, thereby meeting the dynamic support requirements when the cable has a lateral curvature.

[0020] 2. In the present invention, by setting an angle adjustment mechanism, various angles of support between the cable and the fixed bracket can be met. By setting a deflection mechanism, the angle between roller one and roller two can be adjusted. At the same time, by not fixing the angle between the deflection bracket and the bearing bracket, the deflection bracket can rotate when the cable shakes back and forth laterally, avoiding the problem of the traditional roller bearing force frame where the cable is offset from the roller when shaking laterally.

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figures 1 to 5 As shown, this embodiment proposes a roller-type cable bearing frame, including a fixed bracket 1, a bearing bracket 2, a roller 3, an angle adjustment mechanism and a deflection mechanism. The fixed bracket 1 is fixedly installed on the bridge or tower, the bearing bracket 2 is rotatably connected to the end of the fixed bracket 1 away from the bridge, the roller 3 is rotatably connected to the bearing bracket 2, the angle adjustment mechanism is arranged on the fixed bracket 1 and the end of the bearing bracket 2 away from the roller 3, the angle adjustment mechanism is used to fix the rotation angle of the bearing bracket 2 on the fixed bracket 1, and the deflection mechanism is rotatably connected to the bearing bracket. 2 is close to the end of the angle adjustment mechanism, the deflection mechanism includes roller 2 4, roller 1 3 and roller 2 4 jointly support the cable, and the deflection mechanism is used to adjust the lateral deflection angle of the cable when supporting the cable. In this application, the angle adjustment mechanism is used to simply adjust the rotation angle of the bearing bracket 2. The bearing bracket 2 is parallel to the general direction of the cable. When the cable has a lateral turning angle at the bearing frame, the deflection mechanism can be used to make a certain angle between roller 1 3 and roller 2 4, so that the cable can maintain a certain curvature when dynamically supporting the cable.

[0032] like Figures 1 to 2 As shown, one end of the fixed bracket 1 close to the bearing bracket 2 is set to be inclined. When the bearing bracket 2 is rotated to be parallel to the fixed bracket 1, the bearing bracket 2 is on one side of the fixed bracket 1. By setting one end of the fixed bracket 1 to be inclined, the bearing bracket 2 can be rotated to the side of the fixed bracket 1. At the same time, since roller 1 3 and roller 2 4 are respectively set on the side of the bearing bracket 2 and the deflection bracket 11, the cable can be supported by the bearing frame in a direction parallel to the fixed bracket 1, so that the fixing bracket can be installed in a variety of ways, and various angles of the cable can be supported by the bearing frame.

[0033] like Figures 1 to 4As shown, the angle adjustment mechanism includes a locking plate 5, a fixing hole 6, a slide 7 and a docking pin 8. There are two locking plates 5, which are fixedly connected to the bearing bracket 2. The two locking plates 5 are respectively arranged on the upper and lower sides of the fixed bracket 1. There are multiple fixing holes 6, and multiple fixing holes 6 are circumferentially opened on the locking plate 5. The slide 7 is fixedly connected to the fixed bracket 1. The slide 7 is arranged between the two locking plates 5. A groove is opened on the side of the slide 7. There are two docking pins 8. The two docking pins 8 are arranged in opposite directions in the slide 7. A spring is provided between the two docking pins 8. , both butt pins 8 can slide out of the slide cylinder 7 and then extend into the fixing hole 6. The locking plate 5 has multiple fixing holes 6 on both sides of the bearing bracket 2. Multiple fixing holes 6 are convenient for multi-angle fixation. The fixing bracket 1 rotates between the two locking plates 5, and the two locking plates 5 are fixed respectively by the two butt pins 8 on both sides of the slide cylinder 7, so that the fixation of the bearing bracket 2 is more stable. A protrusion is provided on the side of the butt pin 8 close to the spring, and the protrusion passes through the groove. The butt pin 8 is driven to slide in the slide cylinder 7 by squeezing the protrusion, so that the butt pin 8 is separated from the fixing hole 6.

[0034] like Figures 1 to 5 As shown, the bearing bracket 2 is fixedly connected with a rotating shaft 19 and a rotating shaft 2 10, the fixed bracket 1 is rotatably connected to the rotating shaft 19, the deflection mechanism is rotatably connected to the rotating shaft 2 10, the rotating shaft 19 is at the center of the locking plate 5, and a clamping ring 13 is rotatably provided on the bearing bracket 2. The clamping ring 13 is provided in the center of the locking plate 5 on the upper side. When the deflection bracket 11 is parallel to the bearing bracket 2, the clamping ring 13 is in the center of the roller 1 3 and the roller 2 4. The clamping ring 13 is set in a C shape and is made of elastic material. The cable passes through the center of the clamping ring 13 under the support of the roller 1 3 and the roller 2 4. When the rotating shaft 1 9 and the rotating shaft 2 10 are used as the axis of rotation, they also rotate the shaft. The bearing bracket 2 and the deflection bracket 11 support the cable, and the cable can be extended into the clamping ring 13 at the opening on the clamping ring 13. When the cable slides on roller 1 3 and roller 2 4, the cable slides in the clamping ring 13. The clamping ring 13 can prevent the cable from tilting upward when sliding on roller 1 3 and roller 2 4, causing the cable to detach from the bearing frame. A frame for pressing the cable can also be set above roller 1 3 and roller 2 4. At the same time, the cable is supported between roller 1 3 and roller 2 4 by the clamping ring 13. When the deflection bracket 11 rotates, the cable can bend at the clamping ring 13, so that the cables on both sides of the clamping ring 13 can be tightly attached to the sides of roller 1 3 and roller 2 4 respectively.

[0035] like Figures 4 and 5As shown, the deflection mechanism also includes a deflection bracket 11 and a support rod 12. The deflection bracket 11 is rotatably connected to the rotating shaft 2 10, and the roller 2 4 is rotatably connected to the end of the deflection bracket 11 away from the rotating shaft 2 10. The support rod 12 is rotatably connected to the deflection bracket 11, and the end of the support rod 12 away from the deflection bracket 11 is detachably connected to the fixing hole 6. The support rod 12 also fixes the deflection angle of the deflection bracket 11 by connecting to the fixing hole 6. The deflection bracket 11 drives the roller 2 4 to deflect, so that the roller 1 3 and the roller 2 4 maintain a certain angle. When there is a certain angle between the parts of the cable on both sides of the bearing frame, the cable can be supported by rotating the deflection bracket 11.

[0036] like Figures 1 to 4 As shown, roller one 3 and roller two 4 are respectively rotatably connected to the bearing bracket 2 and the deflection bracket 11 on one side close to the clamping ring 13, the docking pin 8 and the support rod 12 can be detachably connected to the fixing holes 6 on both sides of the bearing bracket 2, respectively, and roller one 3 and roller two 4 are respectively rotatably arranged on the sides of the bearing bracket 2 and the deflection bracket 11. A balancing wheel 14 is fixedly connected to roller one 3 and roller two 4. When roller one 3 and roller two 4 rotate, the balancing wheel 14 can prevent the weight of the cable from causing roller one 3 and roller two 4 to deviate sideways.

[0037] In this embodiment, the cable is placed on roller 1 3 and roller 2 4, and passes through the clamping ring 13. The protrusions on the two docking pins 8 are pulled so that the two docking pins 8 slide toward each other and the docking pins 8 are separated from the fixing holes 6. At this time, the bearing bracket 2 is rotated to the required angle and the docking pin 8 is released. The spring is extended to push the docking pin 8 into the fixing hole 6. After the cable is laterally bent, the support rod 12 is separated from the fixing hole 6, and the support rod 12 is connected to the corresponding fixing hole 6 after the deflection bracket 11 is rotated to the required angle. When the cable shakes back and forth laterally, the support plate can be removed.

[0038] Example 2

[0039] like Figure 6 As shown, the rotating shaft 2 10 can be set to be detachably connected to the bearing bracket 2. After the rotating shaft 2 10 is removed, the deflection bracket 11 is separated from the bearing bracket 2. At this time, the bearing bracket 2 can rotate 180 degrees on the rotating shaft 1 9. At this time, the deflection bracket 11 is connected to the rotating shaft 2 10 and the bearing bracket 2. At this time, the relative positions of the roller 1 3 and the roller 2 4 are interchanged. When supporting the cable, the deflection bracket 11 can be rotated. Since the fixed bracket 1 is difficult to move after being fixed, the position of the deflection bracket 11 can be changed to meet the direction of various cable deflections.

[0040] Example 3

[0041] A method for applying a roller-type cable bearing frame, using the above-mentioned roller-type cable bearing frame, includes the following steps:

[0042] Step 1: Angle adjustment: squeeze the two docking pins 8 at the same time. The springs are compressed and shortened. The two docking pins 8 are separated from the fixing holes 6 on the two locking plates 5. After rotating the bearing bracket 2 to the required angle, release the docking pins 8.

[0043] Step 2: Deflection adjustment: disconnect the support rod 12 from the fixing hole 6, rotate the deflection bracket 11 to the required angle, and then connect the support rod 12 to the fixing hole 6;

[0044] Step 3: Fix the cable: Place the cable on roller 1 3 and roller 2 4, and pass the cable through the clamping ring 13;

[0045] Step 4: Support the cable: When the cable is pulled in the axial direction, the cable slides on roller 1 3 and roller 2 4, driving roller 1 3 and roller 2 4 to rotate.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
