Description

Technical Field

[0001] This invention relates to a network-connected cross-traffic vehicle group and its usage method, belonging to the technical field of power grid construction. Background Technology

[0002] In the process of modern power grid construction, with the continuous expansion and optimization of power grid coverage, it is inevitable that power lines will need to cross important lines such as highways and railways. Against this backdrop, equipment for crossing power grids has become a key tool to ensure the smooth progress of power grid construction. The core purpose of using this equipment is, on the one hand, to ensure that power lines can safely and stably cross these transportation routes, avoiding interference with the normal erection and subsequent operation of the power grid; on the other hand, it is also to ensure the safe passage of highways, railways, and other lines beneath the power lines, preventing any situations that may endanger the safety of traffic facilities and personnel during construction.

[0003] Currently, common methods of netting enclosure mainly include scaffolding type, suspension bridge type, double-track propulsion type, rotating boom type, umbrella type, and boom deployment type. Among them, the scaffolding type netting enclosure method has become the most widely used construction method due to its relatively simple structure. When constructing a scaffolding type netting enclosure, it is necessary to first erect a scaffolding frame, and then manually build the protective netting on the scaffolding frame for the netting operation. This construction method is not only inefficient, but also poses significant safety hazards.

[0004] To address this, Chinese patent application CN202311865914.X discloses a device and method for crossing gantry fences. In use, the hoisting mechanism is first controlled to raise the telescopic boom to a sufficient height. Once the boom is at the required height, its rotation and horizontal extension allow it to smoothly cross highways, railways, and other lines, enabling the gantry to deploy and the netting to be laid. This method offers advantages such as improved construction efficiency, no need for personnel to climb, and good safety. However, in practical use, the following problems exist: It uses only a one-sided support structure, with one side supported by a crane and the other side by a structure such as a truss beam. The mechanical properties of the crane support and the truss beam structure are different. The crane support mainly relies on the outriggers of the crane to transfer the load to the ground, while the truss beam distributes the load through the combination of members. This makes it difficult to ensure that the stress on the two supporting structures is uniform during construction when these two different support methods are used in combination, which poses a significant risk of structural damage. At the same time, the position and form of the truss beam structure are relatively fixed and difficult to adjust flexibly. When encountering external loads such as wind, it is impossible to adjust in time to cope with the load. This makes the response of the entire operating equipment to external loads very complex, and the overall stability is difficult to control well. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a networkable, interconnected cross-traffic vehicle group and its usage method.

[0006] The technical solution of the present invention is as follows: In a first aspect, the present invention provides a network-connected cross-traffic vehicle group, including at least one safety net body and a pair of cross-traffic vehicles. Each cross-traffic vehicle includes a frame structure with electric wheels, and a telescopic arm is provided on the frame structure. The top of the telescopic arm is movably connected to one end of a symmetrically arranged crossbeam. The two crossbeams can be unfolded and folded at the top of the telescopic arm. Each end of the two crossbeams away from the telescopic arm is provided with a first pulley for passing through a first load-bearing rope. When the two crossbeams on the two cross-traffic vehicles are in the unfolded state, the first load-bearing rope connects the corresponding crossbeams together by passing through the first pulleys on the corresponding sides of the two cross-traffic vehicles. At this time, the safety net body is hung on the first load-bearing ropes on both sides to complete the net enclosure.

[0007] Furthermore, each of the two crossbeams on the crossing vehicle is provided with a first lug for attaching a first ground anchor rope at the end furthest from the telescopic arm. When the two crossbeams on the crossing vehicle are in the extended state, one end of the first ground anchor rope is fixedly attached to the first lug, and the other end is fixed to the ground.

[0008] Furthermore, pulley brackets are also provided on the ends of the crossbeams on both sides of the crossing vehicle that are away from the telescopic arm. The pulley brackets are equipped with second pulleys for passing through the second load-bearing rope. The top of the pulley brackets is provided with rope inlets. Symmetrically arranged sealing plates are hinged to the inner wall of the top of the pulley brackets by a hinge shaft. When the hinge shaft is in the normal state, the sealing plates on both sides block the rope inlets. When the second load-bearing rope enters through the rope inlets, the sealing plates on both sides flip downward to avoid it. When the crossbeams on both sides of the crossing vehicle are in the extended state, the second load-bearing rope passes through the second pulleys on the corresponding sides of the crossing vehicle to connect the corresponding side crossbeams together. The safety net body is then hung on the second load-bearing ropes on both sides to complete the net sealing.

[0009] Furthermore, the rope inlet is also provided with symmetrically arranged guide plates, with the two guide plates being inclined to make the rope inlet have a constricted structure.

[0010] Furthermore, the pulley bracket is equipped with symmetrically arranged auxiliary rollers via a placement plate. The auxiliary rollers are located on both sides of the rope inlet and are positioned close to the rope inlet.

[0011] Furthermore, the top of the telescopic arm is provided with symmetrically arranged mounting plates, and a rotating shaft is rotatably connected to the mounting plate. The rotating shaft is fixedly connected to the end of the crossbeam close to the telescopic arm. The crossbeam can be unfolded and folded at the top of the telescopic arm by rotating on the mounting plate through the rotating shaft. The mounting plate has a first pin hole, and the crossbeam has a second pin hole that is adapted to the first pin hole. The second pin hole coincides with the first pin hole when the crossbeam is in the unfolded or folded state. By sequentially inserting fixing pins into the first pin hole and the second pin hole, the crossbeam can be fixed in the telescopic arm state.

[0012] Furthermore, each end of the safety net body is equipped with a traction rope for construction workers to pull the safety net body.

[0013] Furthermore, the top of the telescopic arm is also provided with a second lug for hanging a second ground anchor rope. One end of the second ground anchor rope is fixedly hung on the second lug, and the other end is fixed to the ground.

[0014] Furthermore, the vehicle frame structure is also equipped with a toolbox for storing construction tools, a control console for work control, a generator set for power supply, and hydraulic outriggers for fixing the position of the vehicle frame structure. The control console is electrically connected to the electric vehicle wheels, telescopic boom, generator set, and hydraulic outriggers, respectively.

[0015] Secondly, the present invention provides a method for using the aforementioned networkable and interconnected cross-traffic vehicle group, comprising the following steps: Step 1: Vehicle transportation; Construction workers use transport vehicles to move the two spanning vehicles to their designated positions; Step 2: Position adjustment after placement; Construction workers use a crane to lift the crossing vehicle from the transport vehicle to the designated position, then use a control console to move the crossing vehicle, and finally use a laser rangefinder to measure the distance between the front and rear of the two crossing vehicles to ensure that the two crossing vehicles are parallel. Step 3: Unfold the crossbeams; the construction workers push the crossbeams on both sides so that the crossbeams are unfolded on the telescopic arms; Step 4: Install the first load-bearing rope and the safety net body; the construction workers pass one end of the first load-bearing rope through the first pulley on one of the crossing vehicles. A first load-bearing rope passes through the first pulleys on both sides of this crossing vehicle. Then, the net body is installed by connecting the rope segment of the first load-bearing rope that passes through the first pulley through the rope hook. Step 5: Adjust the telescopic boom; the construction worker controls the telescopic boom to extend upwards to the required height; Step 6: Drone laying out the line; the construction workers use a drone to hold the end of the first load-bearing rope that passes through the first pulley, and control the drone to pass this end of the first load-bearing rope through the first pulley on another crossing vehicle. Then, the drone releases this end of the first load-bearing rope so that it falls to the ground. After that, the construction workers tighten the first load-bearing rope and fix both ends of the first load-bearing rope to the ground. Step 7: Manual netting installation; Construction workers pull the safety net from one of the crossing vehicles to the other, so that the safety net is spread out above the crossing vehicles on both sides, at which point the netting installation is complete.

[0016] The present invention has the following beneficial effects: This invention provides a crossover vehicle assembly and its corresponding usage method. It replaces the traditional crossover vehicle-supported netting structure of the prior art, which uses a crane on one side and a truss beam on the other, with a structure where both sides of the crossover vehicle have the same mechanical properties, resulting in uniform stress distribution and preventing excessive stress on one side, thus reducing the risk of structural damage. Furthermore, the telescopic booms of the crossover vehicles allow for flexible adjustment of their overall height, enabling them to cope with external loads such as wind through synchronized adjustments. This results in a more uniform response of the entire crossover vehicle assembly to external loads, leading to excellent overall stability. Compared to existing technologies, this invention offers advantages such as uniform stress distribution, reduced structural damage, and superior overall stability. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example: Please refer to Figures 1-6 This embodiment provides a network-connected cross-traffic vehicle group 2 and its usage method. The cross-traffic vehicle group 2 includes at least one safety net body 1 and cross-traffic vehicles 2 used in pairs. The number of cross-traffic vehicles 2 in a pair is two. In most cases, the number of safety net body 1 is one and the number of cross-traffic vehicles 2 is a pair, which is sufficient to carry out the required net sealing work. However, if the length of the net sealing position is long, the number of safety net body 1 can also be two or three, and the number of cross-traffic vehicles 2 can also be four or six, etc. The specific settings can be selected according to the actual situation.

[0021] The cross-traffic vehicle 2 includes a frame structure 202 with electric wheels 201. A telescopic arm 203 is fixedly mounted on the top surface of the frame structure 202. The telescopic arm 203 can be a hydraulic telescopic arm or an electric telescopic arm, which are common in the prior art. Since the extension length required for the netting operation is relatively long, a large hydraulic telescopic arm with a lifting height of 16 meters is selected as the telescopic arm 203. One end of a crossbeam 204 arranged symmetrically on both sides is movably connected to the top of the telescopic arm 203. The two crossbeams 204 can be unfolded and folded at the top of the telescopic arm 203. A first pulley 205 for passing through the first load-bearing rope 3 is fixedly mounted on the end of the crossbeam 204 on both sides of the crossbeam 204 away from the telescopic arm 203. The first pulley 205 is vertically mounted on the end of the crossbeam 204. When the two crossbeams 204 on both sides of the crossing vehicle 2 are in the unfolded state, the first load-bearing rope 3 connects the corresponding crossbeams 204 together by passing through the first pulley 205 on the corresponding side of the two crossing vehicles 2. At this time, the safety net body 1 is hung on the first load-bearing ropes 3 on both sides to complete the net sealing.

[0022] In this embodiment, the crossbeam 204 and the telescopic arm 203 are connected in a movable manner through the following structure: the top of the telescopic arm 203 is provided with mounting plates 215 arranged symmetrically on both sides, and rotating shafts 216 are rotatably connected to the mounting plates 215 on both sides. The rotating shafts 216 on both sides are fixedly connected to the ends of the corresponding side crossbeams 204 close to the telescopic arm 203, so that when the rotating shafts 216 on both sides rotate on the mounting plates 215, the crossbeams 204 on both sides can follow the rotation and thus can unfold and fold at the top of the telescopic arm 203. Both mounting plates 215 on both sides are provided with first pin holes 217, and both crossbeams 204 on both sides are provided with second pin holes that are correspondingly positioned to the first pin holes 217. When the crossbeams 204 are in the unfolded or folded state, the second pin holes coincide with the corresponding first pin holes 217. To achieve this configuration, the first pin holes 217 and second pin holes are arranged in a circular array with the center line of the rotating shaft 216 as the array center. To ensure that the crossbeams 204 on both sides can be fixed to the top of the telescopic arm 203, fixing pins 218 are inserted into the first pin holes 217 and second pin holes. By sequentially inserting fixing pins 218 into the first pin holes 217 and second pin holes, the crossbeams 204 on the telescopic arm 203 can be fixed in this position.

[0023] To improve the stability of the crossing vehicle 2 during use, the ends of the crossbeams 204 on both sides of the crossing vehicle 2 away from the telescopic boom 203 are also provided with first hanging ears 206 for hanging the first ground anchor rope 4, and the top of the telescopic boom 203 is also provided with second hanging ears 219 for hanging the second ground anchor rope 5. When the crossbeams 204 on both sides of the crossing vehicle 2 are in the extended state, one end of the first ground anchor rope 4 is fixedly hung on the first hanging ear 206, and the other end is fixed to the ground. When the telescopic boom 203 needs to be fixed, one end of the second ground anchor rope 5 is fixedly hung on the second hanging ear 219, and the other end is fixed to the ground. With the installation of the first ground anchor rope 4 and the second ground anchor rope 5, when the crossing vehicle 2 group is carrying out the netting operation, the first ground anchor rope 4 and the second ground anchor rope 5 are connected to the telescopic arms 203 on both sides of the crossing vehicle 2, so that the telescopic arms 203 can be tightened and anchored in a triangular structure, so that the telescopic arms 203 have a good load-bearing capacity, thereby improving the stability of the crossing vehicle 2 group during use.

[0024] In this embodiment, a toolbox 220 for storing construction tools, a control console 221 for work control, and a generator set 222 for power supply are fixedly installed on the top surface of the frame structure 202. Rectangularly distributed hydraulic outriggers 223 for positioning the frame structure 202 are also fixedly installed on the bottom surface of the frame structure 202. The control console 221 is electrically connected to the electric wheel 201, the telescopic arm 203, the generator set 222, and the hydraulic outriggers 223. Construction personnel can control the working status of the electric wheel 201, the telescopic arm 203, and the hydraulic outriggers 223 through the control console 221. For ease of use, a safety net body 1 can be placed in the toolbox 220 of one side of the crossing vehicle 2. During the subsequent net-pulling process, the safety net body 1 can be directly pulled from this side of the crossing vehicle 2 to the other side of the crossing vehicle 2 without special transportation.

[0025] In this embodiment, the telescopic boom 203 can also be selected as a hydraulic telescopic boom with load detection, which is common in the prior art. The telescopic boom 203 can transmit the load value it receives to the control console 221 in real time for construction personnel to read. By reading this value, the construction personnel can understand the load received by the telescopic boom 203 and make corresponding construction adjustments to ensure the safety of construction.

[0026] For certain construction projects crossing power grids, such as those crossing important facilities like railways or rivers, the construction risks increase significantly. Therefore, such construction typically requires the installation of two layers of safety netting. To meet this requirement, in this embodiment, pulley brackets 207 are also provided on the ends of the crossbeams 204 on both sides of the crossing vehicle 2, away from the telescopic boom 203. Each pulley bracket 207 contains a second pulley 208 for passing through the second load-bearing rope, and each second pulley 208 is vertically installed within the corresponding pulley bracket 207. Each pulley bracket 207 is a rectangular frame structure. Each pulley bracket 207 has a rope inlet 209 at its top. Symmetrically arranged sealing plates 211 are hinged to the inner wall of the top of each pulley bracket 207 via hinge shafts 210. When the hinge shafts 210 are in their normal position, the sealing plates 211 block the rope inlet 209. When the second carrying rope enters through the rope inlet 209, the sealing plates 211 rotate downwards to avoid it, allowing the second carrying rope to enter the pulley bracket 207 through the rope inlet 209. When the crossbeams 204 on both sides of the crossing vehicle 2 are in the extended state, the second carrying rope passes through the second pulleys 208 on the corresponding sides of the crossing vehicle 2, connecting the corresponding crossbeams 204 together. The safety net body 1 is then hung on the second carrying ropes on both sides, completing the net enclosure. At this time, the safety net body 1, together with the safety net body 1 installed on the first carrying rope 3, forms a double-layer net enclosure structure, thus meeting specific construction requirements.

[0027] To facilitate the entry of the second carrying rope into the rope inlet 209, in this embodiment, the rope inlet 209 is also provided with symmetrically arranged guide plates 212. The guide plates 212 on both sides are inclined so that the rope inlet 209 is arranged in a constricted structure, so that when the second carrying rope reaches above the rope inlet 209, it can be guided downward by the guide plates 212 on both sides, thus making it easier to enter the rope inlet 209.

[0028] To facilitate the subsequent laying of the second carrying rope, in this embodiment, the pulley bracket 207 is equipped with symmetrically arranged auxiliary rollers 214 via a placement plate 213. The auxiliary rollers 214 are located on both sides of the rope inlet 209 and are positioned close to it. When the second carrying rope passes through the second pulley 208, the auxiliary rollers 214 can contact the rope walls on both sides of the second carrying rope, thereby assisting the movement of the second carrying rope and limiting its lateral displacement. This ensures that the second carrying rope is less likely to fall off during subsequent laying operations, thus facilitating the laying process.

[0029] The operating procedure for this crossover trainset includes the following steps: Step 1: Vehicle transportation; Construction workers attach the two spanning vehicles 2 to the transport vehicle to secure them, and then use the transport vehicle to transport the two spanning vehicles 2 to the designated landing position. The specific landing position is determined according to the actual construction needs.

[0030] Step 2: Position adjustment after placement; After the transport vehicle transports the two crossing vehicles 2 to the placement position, the construction personnel use a crane to lift the crossing vehicles 2 from the transport vehicle to the designated position. Then, the control console 221 is used to control the electric wheels 201 on the crossing vehicles 2 to move the crossing vehicles 2 and make fine adjustments to the position of the crossing vehicles 2. Finally, a laser rangefinder is used to measure the distance between the front and rear of the two crossing vehicles 2 to ensure that the two crossing vehicles 2 are parallel. After the two crossing vehicles 2 are parallel, the construction personnel use the control console 221 to control the hydraulic outriggers 223 to start extending and fix the position of the crossing vehicles 2 by lifting the electric wheels 201 off the ground.

[0031] Step 3: Unfold the crossbeams 204; the construction workers remove the fixing pins 218, then push the two crossbeams 204, causing them to rotate around the corresponding pivot 216 on the top of the telescopic arm 203 to unfold. After the crossbeams 204 are unfolded, the fixing pins 218 are inserted back into the first pin hole 217 and the second pin hole to fix the crossbeams 204 in place. The above operation is performed on the crossbeams 204 on both crossing vehicles 2.

[0032] Step 4: Install the first load-bearing rope 3 and the safety net body 1; the construction workers pass one end of the first load-bearing rope 3 through the first pulley 205 on one of the crossing vehicles 2. One first load-bearing rope 3 passes through the first pulley 205 on both sides of this crossing vehicle 2. Then, the safety net body is installed by connecting the rope segment of the first load-bearing rope 3 through the first pulley 205 with a rope hook. If the construction requires a double-layer net, the construction workers put the second load-bearing rope into the pulley bracket 207 from the rope inlet 209, so that the second pulley 208 passes through the second load-bearing rope. One second load-bearing rope passes through the second pulley 208 on both sides of this crossing vehicle 2. Then, the safety net body 1 is connected by connecting the rope segment of the second load-bearing rope through the second pulley 208 with a rope hook. Care should be taken not to get tangled with the safety net body 1 on the first load-bearing rope 3.

[0033] Step 5: Install the first anchor rope 4 and the second anchor rope 5; hang one end of the first anchor rope 4 on the first lifting lug, and hang one first anchor rope 4 on each first lifting lug; hang one end of the second anchor rope 5 on the second lifting lug, and hang one second anchor rope 5 on each second lifting lug.

[0034] Step 6: Adjust the telescopic boom 203; the construction personnel use the control console 221 to control the telescopic boom 203 to extend it to the required height; Step 7: Drone laying out the line; the construction workers use a drone to hold the end of the first carrying rope 3 that passes through the first pulley 205, and control the drone to pass this end of the first carrying rope 3 through the first pulley 205 on another crossing vehicle 2. Then, the drone releases this end of the first carrying rope 3 so that it falls to the ground. After that, the construction workers tighten the first carrying rope 3 and fix both ends of the first carrying rope 3 to the ground. If a second carrying rope is installed, the construction workers use the same method to lay out the second carrying rope. After the laying out is completed, the second carrying rope is tightened and both ends of the second carrying rope are fixed to the ground.

[0035] Step 8: Secure the telescopic boom 203; tighten the first ground anchor rope 4 and the second ground anchor rope 5, and then fix the ends of each first ground anchor rope 4 and each second ground anchor rope 5 away from the telescopic boom 203 to the ground.

[0036] Step 9: Manual net pulling; Construction workers use traction ropes 6 to pull the safety net body 1 from one of the crossing vehicles 2 to the other, so that the safety net body 1 is spread out above the crossing vehicles 2 on both sides. Then, they tighten the traction ropes 6 on both sides and fix the ends of the traction ropes 6 away from the safety net body 1 to the ground. At this point, the net sealing work is completed.

A method of using a network-connected cross-traffic trainset as described in any one of claims 1 to 9, characterized in that: Includes the following steps: Step A1: Vehicle transportation; Construction workers use a transport vehicle to transport the two spanning vehicles (2) to the placement position; Step A2: Position adjustment after placement; Construction workers use a crane to lift the crossing vehicle (2) from the transport vehicle to the designated position, and then use the control console (221) to control the crossing vehicle (2) to move. Finally, use a laser rangefinder to measure the distance between the front and rear of the two crossing vehicles (2) to ensure that the two crossing vehicles (2) are parallel. Step A3: Unfold the crossbeam (204); the construction workers push the two crossbeams (204) so ​​that the two crossbeams (204) are unfolded on the telescopic arm (203); Step A4: Install the first load-bearing rope (3) and the safety net body (1); the construction workers pass one end of the first load-bearing rope (3) through the first pulley (205) on one of the crossing vehicles (2). A first load-bearing rope (3) passes through the first pulleys (205) on both sides of this crossing vehicle (2). Then, the net body is installed by connecting the rope segment of the first load-bearing rope (3) that passes through the first pulley (205) through the rope hook. Step A5: Adjust the telescopic boom (203); the construction personnel control the telescopic boom (203) to extend upward to the required height; Step A6: Drone laying out the line; the construction workers use the drone to clamp the end of the first carrying rope (3) through the first pulley (205), and control the drone to pass this end of the first carrying rope (3) through the first pulley (205) on another crossing vehicle (2), and then command the drone to release this end of the first carrying rope (3) so that it falls to the ground. After that, the construction workers tighten the first carrying rope (3) and fix both ends of the first carrying rope (3) to the ground. Step A7: Manual netting; the construction workers pull the safety net body (1) from one of the crossing vehicles (2) to the other crossing vehicle (2), so that the safety net body (1) is spread out above the crossing vehicles (2) on both sides, and the netting is then sealed.
