Description

Technical Field

[0001] This invention belongs to the field of power grid construction technology, and specifically relates to a sag adjustment and tightening device for the sealing network of a crossing frame. Background Technology

[0002] Dyneema ropes are widely used in the construction of power transmission lines due to their high strength and good insulation properties. However, during the construction of crossings, when there is rain, snow or fog, the main load-bearing cable and the fiber rope net of the suspension crossing frame become damp, increasing their weight and installation sag. This can lead to insufficient minimum safe distance between the protective net and the contact wire of high-speed railways, highway surfaces, and high-voltage power lines, which can easily cause safety accidents.

[0003] Chinese Patent Application No. 202020395584.8 discloses a sag adjustment and tightening device for a cross-frame sealing net, comprising a left longitudinal beam, a right longitudinal beam, an upper winding wheel, a lower winding wheel, a transmission gear set, an operating connecting plate, and an operating mechanism. The upper winding wheel is rotatably connected to the upper part between the left and right longitudinal beams, and the lower winding wheel is rotatably connected to the lower part between the left and right longitudinal beams. The operating connecting plate is located on the right side of the right longitudinal beam, the transmission gear set is disposed between the operating connecting plate and the right longitudinal beam, and the operating mechanism is disposed on the right side of the operating connecting plate. The operating mechanism is simultaneously connected to both the upper and lower winding wheels via the transmission gear set. This invention has a simple, compact, and small structure, excellent portability, saves time and effort in operation, has high reliability, controllable tightening speed, and good tightening effect.

[0004] In the aforementioned patent, the left longitudinal beam is rotated and opened by bolt pins so that the Dyneema rope can be looped onto the winding wheel. However, the structural strength is generally weak when the bolt pins are used to lock the shaft. Furthermore, the positioning effect is generally weak when the Dyneema rope is tightened by controlling the drive mechanism, and the Dyneema rope cannot be tightened securely. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a sag adjustment and tightening device for cross-type mesh enclosures, which features stable structure and good performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sag adjustment and tightening device for a cross-frame sealing net, comprising a housing, a locking component inside the housing, a power gear installed inside the housing, an operating mechanism connected to the side of the power gear, reduction gears installed on both sides of the power gear, a winding wheel connected to the side of the reduction gear, a rotating sealing plate connected to the side of the housing, and a reinforcing component inside the rotating sealing plate.

[0007] Preferably, the locking assembly includes a connecting plate, a screw, and a locking block. The screw is disposed inside the housing, the connecting plate is sleeved on the surface of the screw, the locking block is connected to the side of the connecting plate, the side end of the locking block has a V-shaped structure, and the locking block meshes with the power gear.

[0008] Preferably, a positioning sleeve is provided on the side of the cover, a rotating groove is provided inside the positioning sleeve, and a circular positioning block is fitted on the surface of the screw inside the positioning sleeve.

[0009] Preferably, both ends of the connecting plate are connected to sliders, and the inner top and inner bottom of the cover are provided with grooves, and the surface of the slider is in close contact with the inner wall of the groove.

[0010] Preferably, the surface of the connecting plate is provided with two biting blocks, which have a tooth-like structure and mesh with the side of the reduction gear.

[0011] Preferably, the reinforcing component includes a control block, a through groove, a spring, a limiting block, and a limiting groove. The rotating sealing plate has a through groove inside, two limiting blocks are embedded inside the through groove, a control block is connected to the side of the limiting block, a spring is provided between the two control blocks, and a limiting groove is provided on the side end of the winding wheel.

[0012] Preferably, the limiting groove has a circular structure, the side end of the limiting block has a U-shaped structure, and the side end of the limiting block is in close contact with the inner wall of the limiting groove.

[0013] Preferably, both the limiting block and the control block have cylindrical grooves inside, and the spring between the two control blocks has a sliding rod embedded inside.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting a locking component, the rotating screw can rotate within the housing under the limiting action of the positioning sleeve on the positioning block. Under the meshing connection between the screw and the locking block, the sliders at both ends of the connecting plate slide and the groove, and the locking block can move at the upper limit of the screw. The locking block will mesh with the power gear to complete the fixed limiting of the operating mechanism, which can make the device have a better tightening and fixing effect on the Dyneema rope.

[0016] 2. By setting up bite blocks, the connecting plate moves and drives two bite blocks to move synchronously and mesh with the reduction gear. The three-point snap-fit ​​positioning method can further improve the rotation orientation of the operating mechanism, thereby making the device more effective.

[0017] 3. By setting up a reinforcing component, the control block can drive the limiting block to engage with the limiting groove on the winding wheel under the elastic force of the spring. This makes the connection between the rotating sealing plate and the winding wheel more stable and the winding tension effect better. The through groove limits the limiting block, and the sliding limit between the slide rod and the limiting block can make the limiting block and the limiting groove firmly engaged.

[0025] Example 1

[0026] Please see Figure 1-5 The present invention provides the following technical solution: a sag adjustment and tightening device for a cross-frame sealing net, comprising a cover 6, a locking component 5 inside the cover 6, a power gear 7 inside the cover 6, an operating mechanism 4 connected to the side of the power gear 7, reduction gears 8 on both sides of the power gear 7, a winding wheel 3 connected to the side of the reduction gear 8, a rotating sealing plate 1 connected to the side of the cover 6, and a reinforcing component 2 inside the rotating sealing plate 1.

The connecting plate 53 is fitted on the surface of the screw 54. The locking block 55 is connected to the side of the connecting plate 53. The side end of the locking block 55 has a V-shaped structure. The locking block 55 meshes with the power gear 7.

[0028] By adopting the above technical solution, when the screw 54 is engaged with the locking block 55, the locking block 55 can move at the upper limit of the screw 54. The locking block 55 will engage with the power gear 7 to complete the fixed limit of the operating mechanism 4, which can make the tightening cable of the device more effective.

[0029] Specifically, a positioning sleeve 56 is provided on the side of the cover 6, and a rotating groove is provided inside the positioning sleeve 56. A circular positioning block 57 is fitted on the surface of the screw 54 inside the positioning sleeve 56.

[0030] By adopting the above technical solution, the rotating screw 54 can rotate within the cover 6 under the limiting action of the positioning sleeve 56 on the positioning block 57, which facilitates the control of the movement of the locking block 55.

[0031] Specifically, both ends of the connecting plate 53 are connected to sliders 51, and the inner top and inner bottom of the cover 6 are provided with grooves 52, and the surface of the slider 51 is in close contact with the inner wall of the groove 52.

[0032] By adopting the above technical solution, the sliding limit between slider 51 and slide groove 52 can play a role in strengthening the structure and can make the engagement between the locking block 55 and the power gear 7 firm.

[0033] Specifically, the surface of the connecting plate 53 is provided with two biting blocks 58, which have a tooth-like structure and mesh with the side of the reduction gear 8.

[0034] By adopting the above technical solution, when the connecting plate 53 moves, it will drive the two biting blocks 58 to move synchronously and mesh with the reduction gear 8, which can further improve the rotation orientation of the operating mechanism 4.

[0035] In this embodiment, the Dyneema rope is looped onto the two winding wheels 3, and then the rotating sealing plate 1 is rotated to close. The rotating screw 54 can rotate within the cover 6 under the limiting action of the positioning sleeve 56 on the positioning block 57. Under the meshing connection between the screw 54 and the locking block 55, the slider 51 at both ends of the connecting plate 53 slides between the slider 51 and the slide groove 52, and the locking block 55 can move at the upper limit of the screw 54. The locking block 55 will mesh with the power gear 7 to complete the fixed limiting of the operating mechanism 4, which can make the tightening and fixing effect of the Dyneema rope better. When the connecting plate 53 moves, it will drive the two biting blocks 58 to move synchronously and mesh with the reduction gear 8. The three-point locking positioning method can further improve the rotation orientation of the operating mechanism 4, thereby making the device more effective.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that the reinforcing component 2 includes a control block 21, a through groove 22, a spring 23, a limiting block 25 and a limiting groove 26. The rotating sealing plate 1 has a through groove 22 inside, and two limiting blocks 25 are embedded inside the through groove 22. The side of the limiting block 25 is connected to the control block 21, and a spring 23 is provided between the two control blocks 21. The side end of the winding wheel 3 has a limiting groove 26.

[0038] Specifically, the limiting groove 26 has a circular structure, the side end of the limiting block 25 has a U-shaped structure, and the side end of the limiting block 25 is tightly fitted with the inner wall of the limiting groove 26.

[0039] By adopting the above technical solution, under the elastic force of the spring 23, the control block 21 can drive the limit block 25 to engage with the limit groove 26 on the winding wheel 3, which can make the connection stability between the rotating sealing plate 1 and the winding wheel 3 higher and the winding tension effect better. Then, the rotating operating mechanism 4 controls the power gear 7 to rotate. Under the meshing transmission of the power gear 7 and the reduction gear 8, the winding wheel 3 can be driven to rotate to complete the tightening operation of the Dyneema rope, which can make the use effect of this sag adjustment tightener of the cross-frame sealing net better.

[0040] Specifically, both the limiting block 25 and the control block 21 have cylindrical grooves inside, and the spring 23 between the two control blocks 21 has a sliding rod 24 embedded inside.

[0041] By adopting the above technical solution, the through groove 22 limits the limiting block 25, and the sliding limit between the slide rod 24 and the limiting block 25 can make the limiting block 25 and the limiting groove 26 firmly connected, which can make the structure more stable.

[0042] In this embodiment, under the elastic force of the spring 23, the control block 21 can drive the limit block 25 to engage with the limit groove 26 on the winding wheel 3, which can make the connection between the rotating sealing plate 1 and the winding wheel 3 more stable and the winding tension effect better. The through groove 22 limits the limit block 25, and the sliding limit between the slide rod 24 and the limit block 25 can make the limit block 25 and the limit groove 26 firmly engaged.

[0043] The structure and working principle of the rotating sealing plate 1, winding wheel 3, operating mechanism 4, cover 6, power gear 7 and reduction gear 8 in this invention have been disclosed in Chinese patent application No. 202020395584.8, which discloses a sag adjustment and tightening device for a cross-frame sealing net. Its working principle is to loop the Dyneema rope onto the two winding wheels 3 and then rotate to close the rotating sealing plate 1. Then, rotate the operating mechanism 4 to control the power gear 7 to rotate. Under the meshing transmission of the power gear 7 and the reduction gear 8, the winding wheel 3 can be driven to rotate to complete the tightening operation of the Dyneema rope.

[0044] The working principle and usage process of this invention: When using this invention, the Dyneema rope is looped onto two winding wheels 3, and then the rotating sealing plate 1 is rotated to close it. Under the elastic force of the spring 23, the control block 21 drives the limiting block 25 to engage with the limiting groove 26 on the winding wheel 3, which can improve the connection stability between the rotating sealing plate 1 and the winding wheel 3 and improve the winding tightening effect. The through groove 22 limits the limiting block 25, and the sliding limit between the slide rod 24 and the limiting block 25 can make the limiting block 25 and the limiting groove 26 firmly engaged. Then, the operating mechanism 4 is rotated to control the power gear 7 to rotate. Under the meshing transmission of the power gear 7 and the reduction gear 8, the winding wheel 3 can be rotated to complete the tightening operation of the Dyneema rope. The sag adjustment and tightening device for the cross-frame sealing net has a better effect. The rotating screw 54 can rotate within the cover 6 under the limiting action of the positioning sleeve 56 on the positioning block 57. Under the meshing connection between the screw 54 and the locking block 55, the slider 51 at both ends of the connecting plate 53 slides between the sliding groove 52 and the locking block 55, so the locking block 55 can move at the upper limit of the screw 54. The locking block 55 will mesh with the power gear 7 to complete the fixed limit of the operating mechanism 4, which can make the tightening and fixing effect of the Dyneema rope better. When the connecting plate 53 moves, it will drive the two biting blocks 58 to move synchronously and mesh with the reduction gear 8. The three-point locking positioning method can further improve the rotation orientation of the operating mechanism 4, thereby making the device more effective.
