Description

Technical Field

[0001] The present invention relates to the technical field of a highway spanning network, and in particular to an installation method of a highway spanning network device. Background Art

[0002] As far as current technology is concerned, overhead transmission line crossing types are mainly divided into crossing methods with crossing frames and crossing methods without crossing frames. The types of crossing frames include bamboo, wooden crossing frames, steel pipe crossing frames, and metal structure wire crossing frames. The crossing system without crossing frames mainly uses auxiliary beams to set up the crossing network, and the main load-bearing rope is generally pulled by drones. Judging from the current types of overhead transmission line crossings, they are generally characterized by high cost, great terrain restrictions, low efficiency, and complex construction processes.

[0003] There are many restrictions on overhead power transmission lines located in mountainous areas and crossing highways. First, the site in the mountainous area is narrow and there are many trees blocking the view, making it difficult to set up a crossing frame and weave the crossing net. Second, crossing the highway requires approval from the local transportation bureau, and the highway is often closed for a short time. If drones are used to transport the traction rope, there is no guarantee that it will be completed in a short time, and drones are prone to emergencies in mountainous areas with dense trees.

[0004] In view of these regional restrictions, a rapid construction method suitable for overhead lines crossing highways in mountainous areas without the use of crossing frames and drones was invented. Summary of the invention

[0005] The purpose of the present invention is to solve the problems of low efficiency, high cost and complicated construction process in the prior art, and to propose a method for installing a spanning net device across a highway.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A method for installing a cross-highway network device comprises the following steps: Step 1: Construction preparation: Before construction, prepare the winding device wrapped with the main load-bearing rope, the net rope, the U-shaped hanging ring, the anchor, the traction device, the transverse rope and the nylon rope according to the actual situation on site.

[0007] Step 2: Pulling the main load-bearing rope: Three workers pull a traction rope respectively across the highway, pass the traction rope to the operator on the opposite side of the highway, and connect it to one end of the main load-bearing rope.

[0008] Step 3: Weaving the spanning net: Connect the transverse ropes to multiple main load-bearing ropes through U-shaped hanging rings, then use multiple traction devices to gradually pull the main load-bearing ropes to the other side of the highway through traction ropes, and at the same time tie multiple transverse ropes in sequence until the entire spanning net covers the highway.

[0009] Step 4: Anchoring the main load-bearing rope and the net-pulling rope: Fix the net-pulling rope to the main load-bearing rope, and use a ground anchor to anchor the other end of the net-pulling rope so that the air height of the spanning net is at a normal height. After tightening multiple main load-bearing ropes through traction devices, use ground anchors to anchor them to the ground.

[0010] In some embodiments, in step one, the winding device wrapped with the main load-bearing rope, U-shaped hanging ring, nylon rope and transverse rope need to be placed on one side of the highway, while the traction device is placed on the other side of the highway, and at the same time, a number of ground anchors and a number of net ropes are placed on both sides of the highway.

[0011] In some embodiments, before pulling the traction rope in step 2, the winding device and the traction device are fixed to the ground using ground anchors respectively, and after the traction rope is handed over to the operator on the opposite side of the highway, the traction device needs to be started to wind the traction rope, leaving the traction rope and the main load-bearing rope in the air.

[0012] In some embodiments, in step three, nylon rope is used to securely tie the transverse rope and the main load-bearing rope to ensure that the transverse ropes are separated by a certain distance and do not slide together. The interval between multiple transverse ropes is 4-5 meters. In step four, a U-shaped hanging ring is used to fix the net rope and the main load-bearing rope.

[0013] In some embodiments, one end of the traction rope is fixedly connected to a buckle, and the traction rope is connected to one end of the main load-bearing rope through the buckle.

[0014] In some embodiments, the winding device includes a support frame, and a first winding disk is rotatably connected to the surface of the support frame via a bearing.

[0015] In some embodiments, a limiting assembly is provided on the side of the support frame, and the limiting assembly includes a fixing plate, a surface of the fixing plate is slidably connected to a limiting rod, and a plurality of limiting holes are opened on the side of the first winding disk.

[0016] In some embodiments, the traction device includes a shell, a second winding drum is rotatably connected to the surface of the shell through a bearing, a traction rope is wrapped around the surface of the second winding drum, a motor is fixedly connected to the side of the shell, one end of the motor output shaft is fixedly connected to the surface of the second winding drum, a wheel rangefinder is fixedly connected to the surface of the shell, and the traction rope is overlapped on the surface of the wheel rangefinder.

[0017] In some embodiments, a guide ring is fixedly connected to the side of the wheeled rangefinder.

[0018] In some embodiments, two mounting plates are fixedly connected to both sides of the shell and both sides of the support frame respectively.

[0019] Compared with the prior art, the present invention provides a method for installing a spanning network device across a highway, which has the following beneficial effects.

[0020] 1. The present invention saves the time of crossing the highway by arranging workers to replace drones to cross the highway to the opposite tower when pulling the main load-bearing rope, ensures that the pulling of the main load-bearing rope and the net rope across the highway is completed within an effective time, and abandons the previously customized crossing net.

[0021] 2. The present invention, by adopting the method of on-site preparation of the spanning net, solves the problem that the spanning net is not suitable for the actual construction site to a large extent, and has the characteristics of high efficiency and simple preparation engineering. According to the advantage of uneven terrain on both sides of the highway in the mountainous area, the main load-bearing rope is anchored by direct ground anchor after being tightened by a traction device, which simplifies the construction process.

[0022] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The present invention solves the problem that the crossing frame cannot be erected due to terrain restrictions. It uses the terrain advantage to replace the drone to pull the main load-bearing rope and the net rope to ensure that the highway is crossed in a short time. The crossing net is compiled on-site to ensure the construction safety of the wire laying project. The main load-bearing rope is anchored by direct ground anchoring, which simplifies the construction process, improves construction efficiency and reduces construction costs.

[0023] Other advantages, objectives and features of the present invention will be described in part in the following description; and in part, will be apparent to those skilled in the art based on an examination of the following; or, may be taught from the practice of the present invention.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-6 A method for installing a cross-highway network device comprises the following steps: Step 1, construction preparation: before construction, prepare the winding device 5, the net rope 3, the U-shaped hanging ring 4, the ground anchor, the traction device 7, the transverse rope 2 and the nylon rope wrapped with the main load-bearing rope 1 according to the actual situation on site. Place the winding device 5, the U-shaped hanging ring 4, the nylon rope and the transverse rope 2 wrapped with the main load-bearing rope 1 on one side of the highway, and the traction device 7 on the other side of the highway. At the same time, place several ground anchors and several net ropes 3 on both sides of the highway.

[0033] Step 2, pulling the main load-bearing rope 1: three workers pull a traction rope 703 respectively across the expressway and pass the traction rope 703 to the operator on the opposite side of the expressway, and connect it to one end of the main load-bearing rope 1. Before pulling the traction rope 703, the winding device 5 and the traction device 7 are fixed to the ground with anchors respectively. After passing the traction rope 703 to the operator on the opposite side of the expressway, the traction device 7 needs to be started to wind the traction rope 703, so that the traction rope 703 and the main load-bearing rope 1 are suspended in the air.

[0034] Step 3, weaving the spanning net: connect the transverse rope 2 with multiple main load-bearing ropes 1 through U-shaped hanging rings 4, and use nylon ropes to firmly tie the transverse ropes 2 and the main load-bearing ropes 1 to ensure that the transverse ropes 2 are separated by a certain interval and do not slide together. The interval between multiple transverse ropes 2 is 4-5 meters. Then, multiple traction devices 7 use traction ropes 703 to gradually pull the main load-bearing ropes 1 to the other side of the highway, and tie multiple transverse ropes 2 in turn until the entire spanning net covers the highway.

[0035] Step 4, anchoring the main load-bearing rope 1 and the net-pulling rope 3: Use a U-shaped hanging ring 4 to fix the net-pulling rope 3 and the main load-bearing rope 1, and use a ground anchor to anchor the other end of the net-pulling rope 3, so that the height of the spanning net in the air is at a normal height. After tightening the multiple main load-bearing ropes 1 through the traction device 7, use ground anchors to anchor them to the ground respectively.

[0036] It can be understood that by arranging workers to replace drones to cross the highway to the other side when towing the main load-bearing rope 1, the time for crossing the highway is saved, and the towing of the main load-bearing rope 1 and the pulling net rope 3 across the highway is ensured to be completed within an effective time. The previously customized spanning net is abandoned, and the method of on-site compilation of the spanning net is adopted. The problem that the spanning net is not suitable for the actual construction site is solved to a large extent. It has the characteristics of high efficiency and simple compilation engineering, and is based on the advantages of uneven terrain on both sides of the highway in mountainous areas.

[0037] Specifically, the length of the transverse rope 2 is 8-9 meters, one end of the traction rope 703 is fixedly connected with a buckle 8, and the traction rope 703 is connected to one end of the main load-bearing rope 1 through the buckle 8.

[0038] It can be understood that by using the buckle 8, the connection or separation efficiency between the traction rope 703 and the main load-bearing rope 1 can be improved.

[0039] Specifically, the winding device 5 includes a support frame 501, and a first winding disk 502 is rotatably connected to the surface of the support frame 501 via a bearing.

[0040] It can be understood that by providing the winding device 5, the first winding drum 502 is used to wind up the main load-bearing rope 1, thereby achieving the purpose of easy carrying and recycling.

[0041] Specifically, a limit assembly 6 is disposed on the side of the support frame 501 , and the limit assembly 6 includes a fixed plate 601 , a surface of the fixed plate 601 is slidably connected to a limit rod 602 , and a plurality of limit holes 603 are opened on the side of the first winding disk 502 .

[0042] It is understandable that by providing the limiting assembly 6 , the limiting rod 602 is inserted into the limiting hole 603 , thereby limiting the rotation of the first winding drum 502 , thereby facilitating limiting the unfolding length of the main load-bearing rope 1 .

[0043] Specifically, the traction device 7 includes a shell 701, a second winding drum 702 is rotatably connected to the surface of the shell 701 through a bearing, a traction rope 703 is wound around the surface of the second winding drum 702, a motor 704 is fixedly connected to the side of the shell 701, one end of the output shaft of the motor 704 is fixedly connected to the surface of the second winding drum 702, a wheeled rangefinder 705 is fixedly connected to the surface of the shell 701, the traction rope 703 is overlapped on the surface of the wheeled rangefinder 705, and a guide ring 9 is fixedly connected to the side of the wheeled rangefinder 705.

[0044] It can be understood that by setting up the traction device 7, the motor 704 drives the second winding disk 702 to rotate, so that the traction rope 703 drives the main load-bearing rope 1 to move gradually, which is convenient for on-site weaving. By setting up the wheel rangefinder 705, it is convenient to detect the moving distance of the traction rope 703, and it is convenient to control the moving distance of the main load-bearing rope 1, so as to ensure that the spacing between the transverse ropes 2 is equal.

[0045] Specifically, two mounting plates 10 are fixedly connected to both sides of the shell 701 and both sides of the support frame 501, and the main load-bearing rope 1 and the transverse rope 2 are both made of Dyneema rope.

[0046] It can be understood that by providing the mounting plate 10, it is convenient to fix the support frame 501 and the housing 701 on the ground to ensure stability.
