Description

Technical Field

[0001] The utility model relates to the technical field of high-rise cable laying, in particular to a high-rise cable laying anti-falling device. Background Art

[0002] For super-high-rise buildings with a height of more than 100 meters in the fields of residential and commercial buildings, vertical laying of cables is a difficult point in super-high-rise electrical construction in mechanical and electrical installation projects. This is because the operating space in the electrical shaft is small, the cable path is long, the specifications are large, there are many floors, the floor height is too high, and communication is difficult. The traditional manual dragging method is used to lay vertical cables in the shaft, which requires a lot of manpower and has great safety risks.

[0003] Existing cable hoisting devices mostly use wire rope traction and lifting as the main method, supplemented by manual dragging. However, when hoisting cables, the weight of the cables themselves is often large, and the cables are damaged during the hoisting process. As the cables rise, their weight increases, and the cables as a whole are prone to falling. The stress points of the pulled cable parts increase, which will cause deformation and damage to the cable structure, and the cable surface will wear against the building surface.

[0004] Therefore how to solve the above-mentioned technical problems just becomes the problem that the utility model faces. Utility Model Content

[0005] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes a high-rise cable laying anti-falling device.

[0006] The technical solution adopted by the utility model to solve its technical problem is: the utility model provides a high-rise cable laying anti-falling device, including a cable pay-off mechanism, a cable conveying mechanism and an anti-falling mechanism. The cable pay-off mechanism is used to reel in the cable and pay out the cable at a certain speed. It includes a fixed frame, a reel and a pay-off motor. The fixed frame is placed on the ground. The fixed frame is rotatably connected with a reel. The reel is used to wind the cable and the reel is connected to the pay-off motor arranged on the fixed frame. The cable conveying mechanism is used to convey the cable released by the cable pay-off mechanism in a specified direction. It includes a frame, a first conveyor belt, a support frame and a second conveyor belt. The frame is placed on the ground. On the ground, a first conveyor belt and a support frame are installed on the frame, and a second conveyor belt is arranged on the support frame. The first conveyor belt and the second conveyor belt are arranged opposite to each other, and a conveying channel for the cable to pass through is formed between the first conveyor belt and the second conveyor belt; there are multiple anti-falling mechanisms, and multiple anti-falling mechanisms are vertically laid on the building wall, which include a pre-installed plate, a lead assembly, a clamping assembly and a sensor. The pre-installed plate is connected to the building wall by bolts, and a lead assembly, a clamping assembly and a sensor are arranged on the pre-installed plate. The lead assembly is used to guide the cable movement path, and the clamping assembly is used to clamp and lock the cable when it falls and is electrically connected to the sensor. The sensor is used to detect the falling speed of the cable.

[0007] Furthermore, the pay-off motor adopts a servo motor to improve its control effect.

[0008] Furthermore, the distance between two adjacent anti-falling mechanisms is 10-20m, and the anti-falling mechanisms are arranged on the building wall in sections.

[0009] Furthermore, the lead-in assembly includes three traction wheels, which are installed on the pre-installed plate in a triangular structure, and two lead-in channels for passing the cables are formed between the three traction wheels; the clamping assembly includes two telescopic rods, which are symmetrically arranged and both are connected to clamping blocks, and the two clamping blocks are provided with clamping grooves, and the two clamping grooves form a clamping opening for biting the cable, and the size of the clamping opening is smaller than the size of the cable.

[0010] Furthermore, a rubber block is installed at the clamping groove, and the provision of the rubber block is conducive to clamping the cable and reducing the wear of the cable.

[0011] Furthermore, the telescopic rod adopts one of an electric cylinder, a hydraulic cylinder or a pneumatic cylinder.

[0012] Furthermore, it also includes a remote controller, which is used to remotely control the cable pay-off mechanism, the cable conveying mechanism and the anti-falling mechanism. When the sensor detects that the cable running speed is greater than the set value, the clamping assembly starts to lock the cable to prevent the cable from continuing to fall due to gravity. Multiple sensors feed back signals to the remote controller. The remote controller analyzes the data and determines the first falling point. According to the first falling point, it finds the reason for the cable falling at this position and re-lays the cable at that location. After the laying is completed, the staff operates the remote controller to open the clamping assembly. At this time, the cable can be re-laid.

[0013] Furthermore, the remote controller adopts an infrared wireless controller, which is electrically connected to the wire-releasing motor, the first conveyor belt, the second conveyor belt and the telescopic rod. The wire-releasing mechanism, the cable conveying mechanism and the anti-falling mechanism can be remotely operated through the remote controller.

[0014] Furthermore, the cable unwinding mechanism also includes a bracket, a rotating seat and a positioning roller. The bracket is installed on a fixed frame, one side of the bracket is in front of the winding drum, and a rectangular opening is provided on the bracket. Four rotating seats are installed at the opening. Four positioning rollers are rotatably connected between the four rotating seats, and a positioning channel for the cable to pass through is formed between the four positioning rollers. This design improves the positioning of the cable during the cable traction and transportation process and reduces the offset.

[0015] Furthermore, a strip hole is opened in the vertical direction of the support frame, and a positioning bolt is arranged in the strip hole. The positioning bolt is connected to the frame of the second conveyor belt to fix the position of the second conveyor belt. With this design, the size of the conveying channel can be changed according to the size of the cable, so that the pre-tightening force of the first conveyor belt and the second conveyor belt on the cable can be adjusted to adapt to the use of cables of different sizes.

[0016] Furthermore, an adjustment hole is provided on the preinstalled plate, a fixing bolt is arranged in the adjustment hole, and the traction wheel is installed on the preinstalled plate through the fixing bolt. In this design, the distance between each traction wheel can be adjusted, which is convenient for the installation and subsequent removal of cables of different sizes.

[0017] Furthermore, the anti-fall mechanism also includes a locking assembly, which is located between the lead assembly and the clamping assembly, and includes a mounting block, a mounting frame, an auxiliary roller and a limit block. There are two mounting blocks and they are symmetrically arranged on the pre-installed plate. Both mounting blocks are rotatably connected to the mounting frames, and the two mounting frames cooperate with the limit blocks arranged thereunder. The opposite ends of the two mounting frames are each rotatably connected to an auxiliary roller for assisting the transportation and clamping of the cable, and the initial distance between the two auxiliary rollers is smaller than the diameter of the cable.

[0018] Furthermore, it also includes a winch, which is installed on the top floor of a high-rise building. The winch includes a body and a steel rope. The steel rope is wound on the outside of the body, and the bottom end of the steel rope passes through the anti-fall mechanism in turn and is connected to the cable. The setting of the winch is not only conducive to the vertical laying of the cable, but also serves the purpose of preventing the cable from falling.

[0019] The beneficial effects of the utility model are as follows: the cable is laid from bottom to top on the high-rise building, and the cable unwinding mechanism and the cable conveying mechanism are used to reduce the traction force on the cable during the rising process from a low place to a high place, thereby saving manpower. The anti-falling mechanism is set in sections, which not only has the traction effect, but also enables the smooth transportation of the cable. When the cable falls, when the sensor detects that the cable running speed is greater than the set value, the clamping assembly starts to lock the cable to prevent the cable from continuing to fall due to gravity. Multiple sensors feed back signals to the remote controller, which analyzes the data and determines the first falling point, finds the reason for the cable falling at this position according to the first falling point, and re-lays the cable at this position. After the laying is completed, the staff operates the remote controller to open the clamping assembly, and at this time, the cable can be re-laid. The entire cable laying work is safer and more intelligent, which greatly improves the laying efficiency of cables in high-rise buildings and ensures the safety performance of cable laying.

[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0028] Embodiment 1:

[0029] like Figures 1 to 5As shown, a high-rise cable laying anti-falling device comprises a cable pay-off mechanism 1, a cable conveying mechanism 2 and an anti-falling mechanism 3. The cable pay-off mechanism 1 is used for winding up the cable and paying out the cable at a certain speed. The pay-off speed of the cable pay-off mechanism 1 is controllable. It comprises a fixed frame 11, a winding drum 12 and a pay-off motor 13. The fixed frame 11 is placed on the ground to play an overall supporting role. The fixed frame 11 is rotatably connected with the winding drum 12. The winding drum 12 is used for winding the cable and the winding drum 12 is connected to the pay-off motor 13 arranged on the fixed frame 11 so that the pay-off motor 13 can drive the winding drum 12 to pay out the cable. The pay-off motor 13 adopts a servo motor to improve its control effect. The cable conveying mechanism 2 is used to convey the cable released by the cable pay-off mechanism 1 in a specified direction. Under the condition of ensuring the uniformity of the cable transportation direction, the labor intensity of manual transportation is reduced, which is conducive to the transportation of the cable from a low place to the wall of a high-rise building. The cable conveying mechanism 2 comprises a frame 21. , a first conveyor belt 22, a support frame 23 and a second conveyor belt 24, the frame 21 is placed on the ground to play an overall supporting role, the first conveyor belt 22 and the support frame 23 are installed on the frame 21, and the second conveyor belt 24 is provided on the support frame 23. The first conveyor belt 22 and the second conveyor belt 24 are arranged opposite to each other, and a conveying channel for the cable to pass through is formed between the first conveyor belt 22 and the second conveyor belt 24. The conveying channel can smoothly transport the cable to the designated position to avoid excessive position deviation during cable transportation and resulting in a decrease in laying position accuracy; there are multiple anti-falling mechanisms 3, and multiple anti-falling mechanisms 3 are vertically laid on the building wall, and the distance between two adjacent anti-falling mechanisms 3 is 10-20m. The anti-falling mechanism 3 is arranged on the building wall in sections, which includes a pre-installed plate 31, a lead assembly, a clamping assembly and a sensor 39. The pre-installed plate 31 is connected to the building wall by bolts, and a lead assembly, a clamping assembly and a sensor 39 are arranged on the pre-installed plate 31.

[0030] Specifically, in the above scheme, the lead assembly is used to guide the cable movement path to prevent the cable from being worn, and includes three traction wheels 32, which are installed on the pre-installed plate 31 in a triangular structure. Two lead channels for passing the cable are formed between the three traction wheels 32. In actual application, the lead channel is selected according to the cable laying path so that the cable passes through the left or right lead channel; the clamping assembly is used to clamp and lock the cable when it falls to limit the cable position, and is electrically connected to the sensor 39, and includes two A telescopic rod 37 is provided, and the telescopic rod 37 adopts one of an electric cylinder, a hydraulic cylinder or a pneumatic cylinder. The two telescopic rods 37 are symmetrically arranged and are both connected with a clamping block 38. The two clamping blocks 38 are provided with clamping grooves 381. The two clamping grooves 381 form a clamping opening for biting the cable, and the clamping opening size is smaller than the cable size. During implementation, the cable is between the two clamping grooves 381. When the sensor 39 detects that the cable is falling, at this time, the clamping assembly is operated to make the two clamping blocks 38 approach the cable and clamp the cable to prevent the cable from continuing to fall.

[0031] Of course, a rubber block 382 is also installed at the clamping groove 381. The setting of the rubber block 382 is conducive to clamping the cable and reducing the wear of the cable.

[0032] During the specific implementation process, this embodiment also includes a remote controller 4, which is used to remotely control the cable pay-off mechanism 1, the cable conveying mechanism 2 and the anti-falling mechanism 3. Specifically, the remote controller 4 adopts an infrared wireless controller, which is electrically connected to the pay-off motor 13, the first conveyor belt 22, the second conveyor belt 24 and the telescopic rod 37. The pay-off mechanism, the cable conveying mechanism 2 and the anti-falling mechanism 3 can be remotely operated by the remote controller 4. During the implementation process, the cable pay-off mechanism 1 is loaded with cables, and the cables enter the cable conveying mechanism 2 and the anti-falling mechanism 3 in turn. According to the actual cable laying requirements, the cables are paid out and transported at a certain speed by operating the remote controller 4, so that the cables can be laid at a certain speed during the laying process. In order to achieve the purpose of automated transportation, the cable can be automatically aligned to avoid unstable laying and difficult positioning due to bending of the cable during laying. At the same time, when the cable falls, when the sensor 39 detects that the cable running speed is greater than the set value, the clamping assembly begins to lock the cable to prevent the cable from continuing to fall due to gravity. Multiple sensors 39 feed back signals to the remote controller 4. The remote controller 4 analyzes the data and determines the first falling point. According to the first falling point, it finds the reason for the cable falling at this position and re-lays the cable at that location. After the laying is completed, the staff operates the remote controller 4 to open the clamping assembly. At this time, the cable can be re-laid.

[0033] Embodiment 2:

[0034] The difference from Example 1 is that, from the perspective of the stability of the cable pay-off position, in order to improve the position of the cable during the cable traction and transportation process and reduce the offset, the cable pay-off mechanism 1 also includes a bracket 14, a rotating seat 142 and a positioning roller 15. The bracket 14 is installed on the fixed frame 11, and one side of the bracket 14 is in front of the winding drum 12, and a rectangular opening 141 is provided on the bracket 14, and four rotating seats 142 are installed at the opening 141. Four positioning rollers 15 are rotatably connected between the four rotating seats 142, and a positioning channel for the cable to pass through is formed between the four positioning rollers 15. The cable can be limited by the positioning channel during the transportation process through the positioning channel to ensure its moving range all around. At the same time, the positioning channel also plays an auxiliary transportation role for the cable, and the cable can contact the positioning roller 15 to improve the transportation effect.

[0035] Embodiment 3:

[0036] The difference from Example 1 is that the distance between the first conveyor belt and the second conveyor belt is adjustable, and the size of the conveying channel can be changed according to the size of the cable, so that the pre-tightening force of the first conveyor belt and the second conveyor belt on the cable can be adjusted to adapt to the use of cables of different sizes. Specifically, a strip hole 231 is opened in the vertical direction of the support frame 23, and a positioning bolt 232 is provided in the strip hole 231. The positioning bolt 232 is connected to the frame body of the second conveyor belt to fix the position of the second conveyor belt; during implementation, by adjusting the positioning bolt 232, the second conveyor belt is moved closer to or away from the first conveyor belt, thereby changing the size of the conveying channel.

[0037] Embodiment 4:

[0038] The difference from the embodiment is that the distance between the traction wheels 32 is adjustable. Specifically, an adjustment hole 311 is opened on the pre-installed plate 31, and a fixing bolt 312 is arranged in the adjustment hole 311. The traction wheel 32 is installed on the pre-installed plate 31 through the fixing bolt 312. During the implementation process, the distance between the two traction wheels 32 can be adjusted according to the cable size to meet the use of the cable, and when the cable is installed, the distance between the two traction wheels 32 is adjusted to facilitate the subsequent removal of the cable.

[0039] Embodiment 5:

[0040] The difference from Example 1 is that the anti-fall mechanism 3 is further provided with a locking assembly for clamping the cable. The locking assembly is located between the lead assembly and the clamping assembly, and includes a mounting block 33, a mounting frame 34, an auxiliary roller 35 and a limit block 36. There are two mounting blocks 33 and they are symmetrically arranged on the pre-installed plate 31. The two mounting blocks 33 are rotatably connected to the mounting frames 34. The two mounting frames 34 cooperate with the limit blocks 36 arranged below them. The opposite ends of the two mounting frames 34 are rotatably connected to a cable auxiliary roller 35. Auxiliary rollers 35 assist in transportation and clamping, and the initial distance between the two auxiliary rollers 35 is smaller than the diameter of the cable; during implementation, the cable passes between the two auxiliary rollers 35. As the cable moves upward, the two auxiliary rollers 35 have no clamping effect on it, and the auxiliary rollers 35 only play a role in assisting transportation and positioning. When the cable falls, the auxiliary rollers 35 are weighed downward and the mounting frame 34 conflicts with the limit block 36. At this time, the distance between the two auxiliary rollers 35 is smaller than the diameter of the cable, and as the cable falls, the two auxiliary rollers 35 clamp the cable.

[0041] Embodiment 6:

[0042] The difference from Example 1 is that Figure 6 As shown, the present embodiment further includes a winch 5, which is installed on the top floor of a high-rise building. The winch 5 includes a body 51 and a steel rope 52, the steel rope 52 is wound on the outside of the body 51, and the bottom end of the steel rope 52 passes through the anti-fall mechanism 3 in turn and is connected to the cable. The arrangement of the winch 5 is more conducive to the vertical laying of the cable, making it more convenient to move the cable upward. At the same time, when the cable falls, the winch 5 can be locked immediately to stop the operation of the steel rope 52, thereby achieving the purpose of preventing the cable from falling to a certain extent.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
