Description

Technical Field

[0001] This invention relates to the field of power construction equipment, and is particularly applicable to overhead line crossing construction. Background Technology

[0002] Overhead lines are crucial infrastructure for transmitting electrical energy. Compared to cable transmission, overhead lines offer advantages such as lower cost, larger transmission capacity, and easier maintenance. They can cover high, medium, and low voltage levels, and are also commonly used for communication lines. During construction, overhead lines frequently need to cross other transmission lines, high-speed railways, highways, ordinary roads, and navigable rivers. Crossing structures are required for these crossings. Existing crossing structures are divided into fixed and mobile types: fixed crossing structures are time-consuming to erect and dismantle, costly, and have low reusability; mobile crossing structures are quick to erect and dismantle but offer poor protection and are unsuitable for lines with large spans or high installation heights. Furthermore, both types of crossing structures require the facilities being crossed to be shut down during erection to ensure safety. Moreover, existing crossing structures are open structures, failing to provide complete protection for the line. A falling line would generate significant impact, and existing crossing structures are relatively weak in resisting such forces. Summary of the Invention

[0003] To address the problems of time-consuming and labor-intensive assembly, poor protection, weak impact resistance, and significant impact on the operation of the facilities being crossed in current overhead line crossing construction, this invention proposes a mobile multi-functional overhead line crossing construction equipment and method. This equipment, in conjunction with ordinary cranes, can achieve rapid crossings of large spans and heights, has strong impact resistance, and the facilities being crossed do not need to be shut down during the crossing process, effectively reducing crossing costs and downtime losses.

[0004] To achieve the above objectives, the technical solution provided by this invention is as follows: A mobile multi-functional overhead line crossing construction equipment includes at least two sets of crossing frames for use. Each set of crossing frames includes an extension corridor and a docking corridor that are connected to each other. Both the extension corridor and the docking corridor are hollow frame structures. One side of the front end of the extension corridor is hinged to the end of the docking corridor. The docking corridor can rotate around the hinge point to switch between two positions: docking with the extension corridor or parallel to the extension corridor. The extended corridor is detachably connected to the telescopic boom of the crane; A corridor docking mechanism and a traction rope docking mechanism are provided at the end of the docking corridor away from the hinge point; The traction rope docking mechanism includes paired traction rope docking rods and traction rope docking sleeves. The traction rope docking rods and traction rope docking sleeves are symmetrically arranged at the front end of the docking corridor about the extension axis of the docking corridor. When the two sets of crossing frames dock, the traction rope docking rod on one docking corridor is inserted forward into the traction rope docking sleeve on the opposite docking corridor. When the two docking corridors come into contact with each other, the disengagement mechanism is triggered, causing the traction rope docking rods and traction rope docking sleeves to disengage from their respective docking corridors. The two traction ropes are connected to each other in the corridor and then disengaged from the corridor.

[0005] Preferably, the lower part of the traction rope docking rod is provided with a locking foot, the locking foot is slidably connected to the inner wall of the docking corridor, and the inner wall of the docking corridor is also slidably connected with a first locking pin, the first locking pin is fitted with a spring, the spring compresses the first locking pin to make the first locking pin engage and lock the locking foot, and the front end of the first locking pin protrudes from the front end of the docking corridor.

[0006] Preferably, the upper outer side of the traction rope docking rod is provided with multiple one-way anti-reverse grooves; the side wall of the traction rope docking sleeve is rotatably connected with at least one anti-reverse tooth that cooperates with the one-way anti-reverse groove.

[0007] Preferably, the anti-reverse tooth is a Z-shaped structure with locking teeth at both ends. The middle part of the Z-shaped structure is hinged to the side wall of the traction rope docking sleeve. The front locking tooth of the Z-shaped structure is located inside the traction rope docking sleeve, and the rear locking tooth of the Z-shaped structure is located outside the traction rope docking sleeve.

[0008] Preferably, a release ring for driving the anti-reverse gear is fitted outside the traction rope docking sleeve and in front of the rear end locking teeth.

[0009] Preferably, the unidirectional anti-reverse groove is a tapered structure with a front diameter smaller than the rear diameter.

[0010] Preferably, the front end face of the traction rope connecting rod has an arc-shaped structure.

[0011] Preferably, the inner cavity of the traction rope docking sleeve is slidably connected to a second locking pin that is drivenly connected to the traction rope docking rod along its radial direction. The lower part of the traction rope docking sleeve is provided with a slide rail, and the inner side wall of the docking corridor is provided with a sleeve groove that cooperates with the slide rail. The second locking pin passes outward through the side wall of the traction rope docking sleeve and then inserts into the sleeve groove.

[0012] Preferably, the second locking pin includes a locking ring and a locking pin connected to each other. The upper end of the inner ring of the locking ring is provided with a baffle that cooperates with the traction rope docking rod. The lower end of the locking pin passes through the side wall of the traction rope docking sleeve and is inserted into the sleeve groove.

[0013] Preferably, the front end of the extended corridor is hinged with a through-type support, and the docking corridor and the extended corridor are hinged or docked to each other through the through-type support. The front end of the lower half of the through-type support is detachably connected to the telescopic arm of the crane.

[0014] Preferably, the through-type support is a hollow frame structure; The lower half of the through-type support is detachably connected to a support plate at its front end. The support plate extends rearward through the inner cavity of the through-type support and connects to the front end of the telescopic arm.

[0015] Preferably, a receiving plate locking mechanism is provided between the receiving plate and the through-type support; The receiving plate locking mechanism includes a support frame, which is connected to the through-type bracket. Each of the upper and lower ends of the support frame is threaded with a receiving plate locking pin. Both the upper and lower ends of the receiving plate are provided with through-type bracket connecting legs that cooperate with the receiving plate locking pins.

[0016] Preferably, a rotating plate is hinged to one end of the docking corridor near the extension corridor, and one side of the rotating plate is hinged to the side of the through-type support.

[0017] Preferably, a corridor tilt adjustment mechanism is provided between the rear end of the upper half of the through-type support and the extended corridor, and between the front of the rotating plate and the docking corridor.

[0018] Preferably, the corridor tilt adjustment mechanism includes a helical push rod hinged to a through-type bracket or a rotating plate. The helical push rod is threaded with a rotating nut, which is hinged to the corridor on the corresponding side. Through the transmission action of the helical push rod and the rotating nut, the corridor can rotate at a set angle in the vertical plane to form different angles with the boom of the crane.

[0019] Preferably, the rear end of the lower half of the through-type support is detachably connected to the boom of the crane.

[0020] Preferably, both the extension corridor and the docking corridor are straight structures with a U-shaped vertical cross-section.

[0021] This invention also discloses a method for construction using the aforementioned mobile multi-functional overhead line crossing construction equipment, comprising the following steps: Step 1: Arrange the docking corridor and the extension corridor side by side and fix them to each other. Fix the extension corridor to the boom of the crane. The crane travels to the predetermined position and carries out the hoisting normally after arriving at the site. After the hoisting is completed, the telescopic boom is retracted, the fixed relationship between the extension corridor and the boom is released, and the extension corridor is connected to the head of the telescopic boom. Step 2: The docking corridor rotates to the docking position with the expansion corridor and is fixedly connected to the expansion corridor. The telescopic booms of both cranes extend and are adjusted to the appropriate height according to the span height. They are adjusted to be collinear and set relative to each other. The corridor tilt adjustment mechanism of the two docking corridors works to adjust the angle of the docking corridors so that the two docking corridors are collinear. The telescopic booms of both cranes extend outward and the two docking devices move closer to each other. Step 3: The traction rope docking mechanisms in the two sets of docking equipment approach each other synchronously, the traction rope docking rod is inserted into the traction rope docking sleeve, and it separates from the docking corridor to realize the docking of the traction rope. The traction rope pulls the overhead wire to realize the docking.

[0022] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention allows two sets of crossing frames to connect with each other via connecting corridors, enabling two devices to work together to form a closed crossing corridor. The crossing equipment can be set up without stopping the facilities being crossed, and it can achieve automatic passage of the traction rope and all-round protection of the tension wire. The equipment setup and dismantling process is simple, convenient and quick.

[0023] 2. This invention is mounted on a regular crane. Depending on the voltage level and span height, different sizes of cranes can be used to achieve spans at varying heights. The foldable connection between the docking corridor and the extension corridor enables long-distance spans. When used with regular small and medium-sized cranes, it can achieve safe and redundant spans on highways with ten lanes plus two safety lanes, with a theoretical span distance of 60-100 meters.

[0024] 3. This invention features a switchable connection with the crane boom. During crossing, the equipment body and the supporting crane form an arch-like structure, effectively converting bending moments into axial forces, increasing load-bearing capacity, and effectively coping with impact loads. In addition to forming an arch-shaped component to enhance load-bearing capacity, the cantilevered structure of the extended corridor will collapse and deform after being subjected to the strong impact force generated by cable running, changing from an upturned state to a downward-sloping state, effectively absorbing impact energy.

[0025] 4. By setting up a through-type support and a receiving plate, the present invention connects the crossing construction equipment with the crane without affecting the main function of the crane. The function can be switched at any time according to the progress of the construction operation, retaining the crane function and realizing the crossing function. The whole conforms to the order of the construction operation equipment entering the site. When crossing construction is required after hoisting is completed, it can be switched to crossing equipment in a short time. Attached Figure Description

Detailed Implementation

[0028] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0029] It should be noted that in this invention, the direction in which the crane telescopic boom extends is defined as "forward," the direction in which it retracts is defined as "rear," the direction approaching the ground is defined as "bottom," the direction away from the ground is defined as "top," the surface in contact with the corridor is "front," and the surface away from the corridor is "back." In the crane boom, the part connected to the base is defined as the "boom," and the retractable part is defined as the "telescopic boom."

[0030] like Figures 1 to 4 As shown, the main body of this equipment consists of two sets of crossover frames that are connected to each other. After the two sets of crossover frames are connected, they form a long corridor. The corridor is connected to the boom of the crane 8 through the through-type bracket 4, the temporary fixing mechanism 6 and the support plate 5. With the support of the two cranes, the two crossover frames are connected and used to allow the crossover conductor to pass through the connected corridor and to provide all-round protection for the crossover conductor.

[0031] The structure of the through-type support 4 is as follows Figure 5 and Figure 6 As shown, the device is a U-shaped spatial structure with a corner at the bottom. A support plate is installed at each of the left and right ends of the upper part of the U-shaped spatial structure. The support plate is used to connect the various parts of the corridor. The front side of the frame of the U-shaped spatial structure is detachably connected to the telescopic boom 10 of the crane 8 through a supporting plate 5. The rear side of the frame of the U-shaped spatial structure is detachably connected to the boom 7 of the crane 8 through a temporary fixing mechanism 6.

[0032] like Figure 6 As shown, four sets of support plate connection points 4.3 are symmetrically arranged on the U-shaped front side of the through-type bracket 4. Figure 7 and Figure 8 The front side of the support plate 5 shown has two sets of through-type bracket connecting legs 5.1 symmetrically arranged. The support plate 5 is installed between the telescopic boom 10 of the crane 8 and the through-type bracket 4, serving as a connection and fixation function. The front side of the support plate 5 has through-type bracket connecting legs 5.1, and the rear side has telescopic boom head connecting legs 5.2. For different crane models, depending on the specific situation of the telescopic boom head fixing pad, different structural forms of telescopic boom head connecting legs 5.2 are set on the rear side of the support plate 5. In this embodiment, the support plate 5 is connected to the telescopic boom head by four bolts.

[0033] A type of bracket 4 is installed between the two sets of support plate connection points 4.3 on the same side of the through-type bracket 4. Figure 9 The receiving plate locking mechanism 9 shown is used to connect the receiving plate connection point 4.3 and the connecting leg 5.1 of the through-type bracket. The receiving plate locking mechanism 9 connects or separates the receiving plate 5 from the through-type bracket 4 through the telescopic movement of the receiving plate locking mechanism 9.

[0034] A dual-shaft motor 9.3 is installed in the middle of the receiving plate locking mechanism 9. Each end of the dual-shaft motor 9.3 is connected to a transition sleeve 9.2. The transition sleeve 9.2 is rotatably installed in the support frame 9.4. The outer side of the transition sleeve 9.2 is hexagonal prism. In case of failure of the dual-shaft motor 9.3, a wrench can be used to drive the transition sleeve 9.2 to rotate. The two transition sleeves 9.2 have threads with opposite directions inside. Each transition sleeve 9.2 is threadedly connected to a receiving plate locking pin 9.1. The threads of the two receiving plate locking pins 9.1 also have opposite directions. The end of the receiving plate locking pin 9.1 is conical. The side of the receiving plate locking pin 9.1 is provided with a sliding groove. The sliding groove cooperates with the support frame 9.4, so that the receiving plate locking pin 9.1 can only extend or retract to both ends of the support frame 9.4 and cannot rotate. Driven by a dual-shaft motor 9.3, the two adapter sleeves 9.2 rotate in the same direction. Under the transmission action of the threads, the two receiving plate locking pins 9.1 extend or retract simultaneously. When extended, they insert into the connecting leg 5.1 of the receiving plate connection point 4.3 and the through-type bracket, fixing the receiving plate 5 to the through-type bracket 4. Since the two adapter sleeves 9.2 are rigidly connected to the rotor of the dual-shaft motor 9.3, manual linkage control of the extension and retraction of the receiving plate locking pins 9.1 can be achieved by using a wrench to rotate the hexagon on the outside of the adapter sleeves 9.2, enabling manual adjustment in case of electrical system failure.

[0035] A rotating plate hinge point 4.5 is provided on the outer side of one of the support plates of the through-type bracket 4 for hinged rotating plate 3; a rotating plate fixing groove 4.6 is provided on the front side of the other support plate of the through-type bracket 4; a locking mechanism mounting groove 4.7 is provided on the front side of the other support plate of the through-type bracket 4, between the rotating plate hinge point 4.5 and the rotating plate fixing groove 4.6. The rotating plate 3 is a... Figures 11 to 12 The U-shaped plate-like component shown has multiple hinge points on both its front and back sides. The upper hinge point 3.1 on the front side is the upper hinge point for the docking corridor, and the lower hinge point 3.3 on the front side is the lower hinge point for the docking corridor. These two sets of hinge points connect the rotating plate 3 to the docking corridor 2. On one side of the reverse side of the rotating plate 3, a first through-type support hinge point 3.2 is provided, which is hinged to the rotating plate hinge point 4.5 of the through-type support 4. The front side of the rotating plate 3 is connected to the starting end face of the docking corridor 2. The rotating plate 3 rotates along the axis of the rotating plate hinge point 4.5, causing the docking corridor 2 to rotate around the through-type support 4, thus connecting the docking corridor 2 with the extension corridor 1 to form a longer corridor.

[0036] On the opposite side of the rotating plate 3, a rotating plate fixing interface 3.4 is provided. When the rotating plate 3 rotates to mate with the through-type bracket 4, the rotating plate fixing interface 3.4 is inserted into the rotating plate fixing groove 4.6, and the positions of the rotating plate 3 and the through-type bracket 4 are fixed. The fixing method is that a rotating plate locking mechanism 11 is installed in the locking mechanism mounting groove 4.7, and the Z-shaped locking pin 11.1 of the rotating plate locking mechanism 11 fixes the rotating plate 3 in the rotating plate fixing groove 4.6 of the support plate.

[0037] Rotary plate locking mechanism 11 Figure 10 As shown, it includes two symmetrically arranged Z-shaped locking pins 11.1 at the top and bottom and an adjusting sleeve 11.2 in the middle. The two Z-shaped locking pins 11.1 are connected to the adjusting sleeve 11.2 by threads, and the two threads are reversed. When the adjusting sleeve 11.2 is turned, the Z-shaped locking pins 11.1 at both ends can retract or extend at the same time, realizing the function of manual locking and unlocking.

[0038] like Figure 5 As shown, a set of upper hinge points 4.1 for the extension corridor is provided at the top of the rear side of each of the two support plates above the through-type bracket 4, for hinged connection of the front end of the extension corridor 1. A set of lower hinge points 4.4 for the extension corridor is provided at the lower end of the rear side of the two support plates, above the U-shaped space, for hinged installation of a corridor tilt adjustment mechanism 12, which is as follows: Figure 25 As shown, it includes a spiral push rod connected to a support plate. The spiral push rod is threaded with a rotating nut. The rotating nut is rotatably connected to the expansion corridor 1 through a rotating seat that can rotate in the vertical direction. The drive motor drives the rotating nut to move along the axis of the spiral push rod, thereby driving the expansion corridor 1 to rotate in the vertical plane around the hinge point 4.1 on the expansion corridor, thus realizing the tilt angle adjustment function of the expansion corridor 1.

[0039] The hinge point 3.1 on the docking corridor of the rotating plate 3 is also hinged to a corridor tilt adjustment mechanism 12. The corridor tilt adjustment mechanism 12 includes a spiral push rod, which is threadedly connected to a rotating nut. The rotating nut is rotatably connected to the docking corridor 2 through a rotating seat that can rotate in the vertical direction. The drive motor drives the rotating nut to move along the axis of the spiral push rod, thereby driving the docking corridor 2 to rotate up and down in the vertical plane around the axis of the lower hinge point 3.3 of the docking corridor, thus changing the horizontal angle of the docking corridor 2.

[0040] Both the docking corridor 2 and the extension corridor 1 are symmetrically configured with two corridor tilt adjustment mechanisms 12 about their own axes. The two mechanisms ensure uniform force distribution and safety redundancy.

[0041] Connecting corridor 2, as Figure 13As shown, it is a U-shaped vertical passageway component. The outer perimeter of the connecting corridor is a truss-type frame 2.3 (including two side frames and a bottom frame connecting the two side frames) to provide strength. A cover plate 2.2 is provided on the inner side of the truss-type frame 2.3 to ensure smooth passage of components such as walkways and wires. A reinforcing frame 2.1 is added to the rear truss of the connecting corridor 2. This reinforcing frame 2.1 is connected to the lower hinge point 3.3 of the connecting corridor below the front of the rotating plate 3. At the other end of the docking corridor 2, a reinforcing truss 2.4 is installed. This reinforcing truss 2.4 is a multi-specification hollow frame formed by multiple inclined support rods. The inclined support rods can effectively increase the structural strength, enabling it to withstand larger bending moments and shear forces. Two sets of temporary fixing mechanisms are arranged inside the reinforcing truss 2.4 to connect the docking corridors of the two devices together to form a stable whole. At the docking position of the two docking corridors 2, two sets of traction rope docking mechanisms are arranged inside the truss-type frame 2.3, which can dock the traction ropes arranged on the two devices together to form a continuous rope. Pulling the traction rope from one side can realize the function of the traction rope passing through, without the need to use drones to pull the traction rope, thus ensuring the safety of crossing from the source.

[0042] The structure of the extension corridor 1 is similar to that of the connecting corridor 2, and it is also equipped with a truss-type frame 2.3, a cover plate 2.2 and a reinforcing frame 2.1. The difference is that the rear end of the extension corridor 1 is not equipped with a reinforcing truss 2.4.

[0043] like Figures 13 to 14 As shown, during construction, the front ends of the docking corridors 2 of the two sets of crossing frames approach each other. A traction rope docking mechanism is installed at the front end of the docking corridor 2. This mechanism consists of two parts: a traction rope docking sleeve 14 and a traction rope docking rod 13 that cooperate with each other. Each part has a traction rope connected to its opposite end. After docking, the two parts can detach from the docking corridor 2 and connect together, thus connecting the traction ropes at both ends to form a continuous rope. In this way, the traction ropes are connected without the aid of drones. One side of the traction rope connects to the next level traction rope, and the other side pulls on the traction rope, continuously pulling on thicker ropes until the guide wire is pulled. The traction rope docking mechanism is installed on the left and right inner side walls at the front end of the docking corridor 2. When the two docking corridors 2 are docked, two continuous traction ropes are formed, providing double-layer connection safety.

[0044] The specific structure and working principle of the traction rope docking mechanism are as follows: The structure of the traction rope connecting rod 13 is as follows Figures 15 to 17 As shown, the main body is a cylindrical component with a spherical head. The spherical head can push open the baffle 23.1 of the second locking pin 23, allowing it to slide upwards. The outer surface of the cylindrical component is provided with multiple one-way anti-reverse grooves 13.1. Each one-way anti-reverse groove 13.1 is a conical structure with a front diameter smaller than a rear diameter. This structure is similar to... Figure 19 The anti-reverse teeth 17 in the traction rope docking sleeve 14 shown cooperate with each other, and the anti-reverse teeth 17 are engaged in the one-way anti-reverse groove 13.1, thus fixing the traction rope docking rod 13 and the traction rope docking sleeve 14 into a whole. Two locking feet 13.2 are provided along the axis of the lower side of the main body of the traction rope docking rod 13 from front to back. Each locking foot 13.2 includes a vertical connecting plate and a horizontal locking plate, forming an L-shaped structure. The horizontal locking plate is inserted into the lower locking seat 20. The locking seat 20 has a through-slot groove inside, in which a first locking pin 22 is slidably connected. Two slot openings are spaced apart on the upper surface of the locking seat 20. These slot openings are horizontal T-shaped structures, and the horizontal locking plate is inserted into the larger opening of the T-shaped structure. The structure of the first locking pin 22 is as follows: Figure 18 As shown, two inverted L-shaped latches 22.1 are arranged on its upper surface along its direction of movement. The latches 22.1 protrude upwards from the opening of the T-shaped structure of the slide groove and slide slidably connect with the opening of the T-shaped structure. A spring 21 is provided between the latches 22.1 and the end of the smaller opening of the T-shaped structure. The spring 21 is fitted onto the outside of the first locking pin 22, the front end of which protrudes from the front side of the locking seat 20. When the first locking pin 22 slides along the slide groove to its frontmost position, the latches 22.1 of the first locking pin 22 precisely engage with the transverse locking plate, fixing the two locking feet 13.2 to the locking seat 20. The restoring force of the spring 21 presses the first locking pin 22 to the front end of the locking seat 20, fixing the traction rope connecting rod 13 to the locking seat 20. Since the head of the first locking pin 22 extends out of the front side of the locking seat 20 at this time, when the head of the first locking pin 22 is pressed by the opposite connecting corridor 2, it slides backward along the slide groove. The spring 21 is compressed, and the latch 22.1 will move away from the transverse locking plate of the locking foot 13.2. Since the fixing point of the transverse locking plate and the width of the transverse locking plate are wider than the slide groove, the traction rope connecting rod 13 will not move backward along the locking seat 20. After the first locking pin 22 moves backward a certain distance, the first locking pin 22 will no longer lock the locking foot 13.2 of the traction rope connecting rod 13, and the traction rope connecting rod 13 will separate from the locking seat 20.

[0045] like Figure 19-21As shown, the main body of the traction rope docking sleeve 14 is a horizontally placed hollow cylindrical component. The tail of the component is flared. The cylindrical inner cavity of the traction rope docking sleeve 14 is used to accommodate the traction rope docking rod 13. The flared design can guide the traction rope docking rod 13 to slide smoothly into the traction rope docking sleeve 14 when the traction rope docking rod 13 and the traction rope docking sleeve 14 are not on the same axis, thereby reducing the requirements for docking accuracy. The side wall of the traction rope docking sleeve 14 is rotatably connected to multiple anti-reverse teeth 17. The anti-reverse teeth 17 are Z-shaped structures with locking teeth at both ends. The middle part of the Z-shaped structure is hinged to the side wall of the traction rope docking sleeve 14. The front locking tooth of the Z-shaped structure is located inside the traction rope docking sleeve 14, and the rear locking tooth of the Z-shaped structure is located outside the traction rope docking sleeve 14. A release ring 18 is fitted in front of the rear locking tooth on the outside of the traction rope docking sleeve 14. The anti-reverse teeth 17 rotate towards the inner side of the cylindrical cavity along the hinge point with the traction rope docking sleeve 14, which can lock the one-way anti-reverse groove 13.1 on the surface of the traction rope docking rod 13. Pulling the release ring 18 backward causes the rear locking tooth to rotate towards the inside of the traction rope docking sleeve 14 along the hinge point, and the front locking tooth to rotate towards the outside of the traction rope docking sleeve 14 and disengage from the one-way anti-reverse groove 13.1. The traction rope docking rod 13 and the traction rope docking sleeve 14 then disengage from each other.

[0046] A radial locking groove with vertical penetration is provided on the side wall of the traction rope docking sleeve 14 behind the release ring 18, and a second locking pin 23 is slidably connected in the radial locking groove. Figure 20 As shown, the second locking pin 23 includes an elliptical locking ring 23.2 and a locking pin 23.3 installed at the lower end of the locking ring 23.2. The lower end of the locking pin 23.3 penetrates downward through the side wall of the traction rope docking sleeve 14 and then inserts into the sleeve base 19. A wedge-shaped baffle 23.1 is provided at the upper end of the inner ring of the locking ring 23.2. Figure 21 As shown, the upper surface of the sleeve base 19 is machined with a sleeve groove 19.1. The vertical cross-section of the sleeve groove is an inverted T-shape. The lower end of the traction rope connecting sleeve 14 is provided with an inverted T-shaped slide rail that can slide back and forth along the sleeve groove 19.1, realizing the sliding connection of the traction rope connecting sleeve 14 and the sleeve base 19 in the front-back direction and the limiting in the left-right and up-down directions. A locking hole 19.2 is provided at the center of the upper surface of the sleeve groove 19.1. The locking pin 23.3 is inserted downward into the locking hole 19.2, realizing the fixation of the second locking pin 23 and the sleeve base 19 in the front-back direction. The combination of the limiting in the three directions realizes the fixed connection between the traction rope connecting sleeve 14 and the sleeve base 19.

[0047] When the traction rope docking rod 13 passes through the anti-reverse tooth 17 and touches the baffle 23.1 inside the second locking pin 23, the locking ring 23.2 will move upward under the pressure of the traction rope docking rod 13. At this time, the locking pin 23.3 moves upward and no longer inserts into the locking hole 19.2. The traction rope docking sleeve 14 separates from the sleeve base 19, realizing the function of automatically detaching from the inner wall of the docking corridor 2 after the traction rope docking rod 13 and the traction rope docking sleeve 14 are docked.

[0048] On the top of the boom 7 of crane 8, a set of... Figure 22 The temporary fixing mechanism 6 shown includes a fixing plate 6.1 and a locking motor 6.2. The inner side of the fixing plate 6.1 is connected to the boom 7, and the locking motor 6.2 is installed on the outer side of the fixing plate 6.1. The output shaft of the locking motor 6.2 is connected to a screw rod, which is threadedly connected to the corridor fixing point 4.2 of the through-type support 4, used to lock or release the boom 7 and the through-type support 4. After the temporary fixing mechanism 6 locks the through-type support 4, the receiving plate locking mechanism 9 unlocks the through-type support 4 from the receiving plate 5, allowing the head of the crane 8 (i.e., the telescopic boom 10) to extend independently, enabling the crane 8 to lift items. After the receiving plate locking mechanism 9 locks the through-type support 4 from the receiving plate 5, the temporary fixing mechanism 6 unlocks the through-type support 4, and the crossing construction equipment is fixedly connected to the telescopic boom 10 of the crane 8, achieving the function of crossing protection. The specific method is as follows: When fixation is required (to achieve crane function), two screws are inserted into the corridor fixing points 4.2 on both sides of the through-type bracket 4, fixing the through-type bracket 4 to the temporary fixing mechanism 6. The extended corridor 1 is then connected to the docking corridor 2 and fixedly connected to the lowermost boom 7 of the crane 8. Subsequently, the equipment's receiving plate locking mechanism 9 unlocks the receiving plate 5 from the through-type bracket 4. The receiving plate 5 is no longer connected to the through-type bracket 4, and the telescopic boom 10 can then extend and retract arbitrarily within a set range with the receiving plate 5 to lift heavy objects, achieving the hoisting function. It should be noted that in this state, the docking corridor 2 needs to be... Figure 1 The state shown is reversed to a state parallel to the extended corridor 1 to prevent it from obstructing the telescopic movement of the telescopic arm 10. For example... Figure 2 As shown, when the telescopic boom 10 extends, the receiving plate 5 will move together with the telescopic boom 10. Since the receiving plate 5 is fitted on the outside of the telescopic boom 10, it will not affect the various functions of the crane.

[0049] When unlocking is required (to achieve the crossing support function), firstly, the telescopic arm 10 retracts into the inner cavity of the main arm 7. The four through-type bracket connecting legs 5.1 on the receiving plate 5 at the head of the telescopic arm 10 connect to the receiving plate connection point 4.3 of the through-type bracket 4. The receiving plate locking mechanism 9 activates, locking the receiving plate 5 and the through-type bracket 4 together, thus connecting the telescopic arm 10 and the through-type bracket 4. The locking motor 6.2 drives the screw to separate from the corridor fixing point 4.2 of the through-type bracket 4, so the crossing device is only connected to the head of the telescopic arm 10. The telescopic arm 10 extends, causing the crossing device to extend. It should be noted that before the telescopic arm 10 extends, the docking corridor 2 needs to be rotated 180°, such as... Figure 3 As shown, it must be connected to the extended corridor 1 and locked with the through-type support 4 before crossing construction can be carried out.

[0050] The method and process for using this equipment to carry out overhead line crossing construction are as follows: Step 1: Preliminary site preparation for hoisting. The initial state of the equipment is as follows: Figure 1 As shown, during transportation, the temporary fixing mechanism 6 and the receiving plate 5 are interconnected with the through-type support 4. This double redundant connection ensures stability during transportation. The docking corridor 2 rotates 180° to be arranged side-by-side with the extension corridor 1. The tail of the docking corridor 2 is fixed to the side of the extension corridor 1 by locks or ropes to prevent it from rotating arbitrarily. Upon arrival at the site, the crane 8 moves to the predetermined position, with its four outriggers extending and supporting the ground to ensure stability. The receiving plate locking mechanism 9 unlocks the receiving plate 5, releasing the temporary fixation between the telescopic boom 10 and the main boom 7. Figure 2 As shown, the crane's cable is connected to the hook. The cable passes through the U-shaped inner cavity of the through-type support 4, and runs along the upper side of the boom 7 and the lower side of the extension corridor 1, allowing for normal cable retraction and extension. Since the telescopic boom 10 passes through the inner cavity of the through-type support 4, it does not affect the lifting of the telescopic boom 10. During lifting, the docking corridor 2 and the extension corridor 1 of the equipment remain relatively fixed to the boom 7. That is, when the crane lifts, the crossing equipment is attached to the boom 7, and the crane can then lift normally. After the lifting is completed, the telescopic boom 10 retracts. The four through-type support connecting legs 5.1 on the receiving plate 5 at the head of the telescopic boom 10 coincide with the receiving plate connection point 4.3 of the through-type support 4. The receiving plate locking mechanism 9 locks the receiving plate 5 and the through-type support 4 together, thus connecting the telescopic boom 10 and the crossing equipment.

[0051] Step 2, during the crossing construction. Two cranes equipped with crossing equipment (8...) Figure 1The crane is positioned as shown in the diagram, typically on either side of a road or river to be crossed, directly beneath the overhead power line under construction. The four outriggers of both cranes 8 extend and support the ground, ensuring stability. The locking motor 6.2 at the head of the temporary fixing mechanism 6 rotates the screw in the opposite direction to disengage, releasing the locking of the through-type support 4. The crossing equipment is then only connected to the telescopic boom 10. At this point, the docking corridor 2 rotates 180 degrees, aligning the rotating plate 3 with the through-type support 4. The adjusting sleeve 11.2 of the rotating plate locking mechanism 11 is adjusted so that the Z-shaped locking pins 11.1 at both ends of the adjusting sleeve 11.2 are inserted into the rotating plate fixing groove 4.6 of the through-type support 4. The docking corridor 2 is then locked and fixed to the extension corridor 1 via the rotating plate 3, allowing the two cranes 8 to proceed with the crossing construction. The telescopic booms 10 of both cranes 8 extend and are adjusted to the appropriate height according to the crossing height, ensuring they are collinear and positioned opposite each other. The tilt adjustment mechanism 12 of the two sets of docking corridors 2 in the two devices operates, adjusting the angle of the docking corridors 2 to make the two sets of docking corridors 2 collinear. The angle of the crane boom is adjusted so that the two sets of docking corridors 2 slowly dock until they are formed. Figure 14 The state shown is as follows. At this point, the two sets of traction rope docking mechanisms and the four sets of corridor docking mechanisms are basically collinear (with slight deviations that can be ignored). Both crane telescopic booms 10 extend outwards, and the two docking devices begin to contact. Because the corridor docking sleeves 16 in both docking devices have a flared design, even with deviations, they can be guided to align with the center. After the corridor docking rod 15 contacts the corridor docking sleeve 16, the front screw of the corridor docking rod 15 begins to rotate. The tail of the corridor docking sleeve 16 has a threaded hole, and the two are threadedly connected. The four pairs of corridor docking mechanisms work simultaneously, equivalent to four sets of large, high-strength bolts connecting the docking corridors 2 on both sides, greatly improving stability.

[0052] The two sets of traction rope docking mechanisms approach each other synchronously. The traction rope docking rod 13 is inserted into the traction rope docking sleeve 14, and the anti-reverse tooth 17 passes through the multi-ring one-way anti-reverse groove 13.1. At this time, the anti-reverse tooth 17 cooperates with the one-way anti-reverse groove 13.1, and the traction rope docking rod 13 is temporarily locked in the inner cavity of the traction rope docking sleeve 14. The traction rope docking rod 13 continues to move forward, and the spherical head hits the baffle 23.1 of the locking ring 23.2. The locking ring 23.2 drives the locking pin 23.3 to move upward. The locking pin 23.3 is no longer inserted into the locking hole 19.2 of the sleeve base 19. Under the power of the traction rope docking rod 13, the traction rope docking sleeve 14 slides out from the sleeve slide groove 19.1 of the sleeve base 19, and the traction rope docking sleeve 14 is unlocked and disengaged from the sleeve base 19. As the two docking corridors 2 continue to approach, the head of the first locking pin 22 touches the sleeve base 19 of the other docking corridor 2, and the latch 22.1 moves backward relative to each other, unlocking the traction rope docking rod 13, which then disengages from the locking seat 20. At this time, the traction rope connected to the traction rope docking sleeve 14 and the traction rope connected to the traction rope docking rod 13 are joined together and separated from the docking corridor 2. The traction rope is pulled from one side, and a thicker traction rope is fixed to the other side, realizing the traction function of the traction rope. As the traction rope pulls a thicker line, and finally pulls the overhead conductor, the extension corridor 1 changes its angle under the action of the two corridor tilt adjustment mechanisms 12, rising to a state consistent with the sag shape of the conductor. When the conductor tension is released, it passes completely inside the corridor, preventing the conductor from exceeding the corridor height, thus achieving full enclosure protection for the conductor. Figure 23 As shown.

[0053] Multiple sets of such... are installed on the sides of both connecting corridor 2 and extending corridor 1. Figure 24 The blocking mechanism shown consists of a motor 25 driving a blocking arm 24. Two sets of blocking mechanisms are arranged opposite each other and used in conjunction. During crossing, the blocking arms 24 are horizontally positioned, and the two blocking arms 24 completely close the cross-section of the corridor, achieving a fully enclosed function. When the crossing is complete and the wire is fixed, and it is necessary to release the wire from the corridor, the blocking arms 24 unfold, forming an open structure with a funnel shape. The crossing corridor moves downward, the wire is released, and the crossing is complete. Throughout the entire crossing process, the wire crosses within the corridor, ensuring safety.

[0054] Once the crossing is complete, the corridor docking mechanisms at both ends of the docking corridor reverse their movement to unlock, and the two cranes retract their telescopic booms by 10.

[0055] This invention enables multi-functional applications. The installation of the equipment and crane 8 does not affect the functionality of crane 8. Before crossing construction, functions such as tower assembly, site preparation, and tensioning equipment setup are required. These tasks necessitate the use of cranes. After site preparation and tower assembly are completed, tensioning is carried out. If crossing construction is involved, crossing equipment is needed. Using the crossing equipment of this invention eliminates the need for crane 8 removal and crossing equipment entry, significantly reducing equipment transportation time, improving efficiency, and lowering costs. Multiple cranes are required during the site preparation phase of crossing construction. Once the crossing begins, the number of cranes used decreases. This equipment is initially used as a crane, and when preparation is complete and fewer cranes are needed, it is used to support the construction of the crossing corridor, maximizing efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
