Description

Technical Field

[0001] This invention relates to cable construction equipment, and more particularly to a cable mounting device. Background Technology

[0002] As power cables are gradually developing towards higher voltage levels and larger transmission capacities, 500kV ultra-high voltage power cable lines are being increasingly promoted. Currently, key technical aspects such as the level of mechanization in cable construction and monitoring of the construction process still need improvement during the construction of 500kV cables.

[0003] When faced with the challenge of lifting large-section cables in confined spaces (such as underground utility tunnels), existing technologies lack a device capable of mounting such cables in such spaces. In construction projects like underground utility tunnels and cable tunnels, the usual method involves arranging tracked cable conveyors at intervals within the tunnel to mount the cables. This process requires manual lifting and positioning of the cables in sections. This method is labor-intensive, inefficient, and generally suitable only for long-distance 10kV and 35kV cables. For 500kV cables, due to their excessive size and weight, manual lifting is difficult, requiring significant manpower or lifting tools. This is time-consuming, labor-intensive, inefficient, and poses considerable construction safety risks. Summary of the Invention

[0004] This invention addresses the problem of lifting large-section cables in underground utility tunnels in existing technologies by providing a cable mounting device for underground utility tunnels.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The underground utility tunnel cable mounting device includes a mobile chassis mechanism and a detachable attitude adjustment mechanism mounted on the mobile chassis mechanism; The mobile chassis mechanism includes a chassis frame, which includes a movable frame and a support frame that are detachably connected.

When positioning component two is fully fitted onto positioning component one, the support frame longitudinal beam is supported on the upper surface of the moving frame longitudinal beam. The fixing assembly includes a first fixing member and a second fixing member that mates with the first fixing member and corresponds to it in a one-to-one manner. The first type of fastener consists of multiple fasteners and is installed on the outer side of the longitudinal beam of the support frame and the outer side of the second type of positioning fastener. The second type of fastener is installed on the outer side of the longitudinal beam of the movable frame and the outer side of the support leg. The first fastener includes a hook, and the second fastener includes a hanging ring that can be hooked onto the hook.

[0007] The positioning components enable the support frame to be quickly positioned on the mobile frame, allowing for pre-fixation of both. After pre-fixation, the fixing components provide further fixation.

[0008] Preferably, the second fixing component includes a fixing plate fixedly installed on the longitudinal beam or support leg of the mobile frame. The fixing plate is equipped with a hinge plate that is perpendicular to the fixing plate and is wider at the top and narrower at the bottom. A handle is hinged to the upper end of the hinge plate. The upper end of the handle is hinged to the hinge plate, and the lower end forms a grip. A pivot is passed through the middle of the handle. One end of the hanging ring is installed on the pivot, and the other end can be hooked onto a hook.

[0011] Preferably, the length direction of the conveying module mounting frame is the conveying direction of the cable conveying module, and the lower end surface of the conveying module mounting frame is provided with hinge seat 1 and hinge seat 2 spaced apart along the length direction. The steering assembly includes a slewing bearing and a slewing triangle mounted on the slewing bearing and capable of rotating under the action of the slewing bearing, with one end of the slewing triangle hinged to a hinge seat. The lifting assembly includes a lifting hydraulic cylinder located at the other end of the slewing tripod, with one end of the lifting hydraulic cylinder hinged to the slewing tripod and the other end hinged to the hinge seat 2. During the extension and retraction of the lifting hydraulic cylinder, it can drive the conveying module mounting frame to rotate around the hinge point of the hinge seat.

[0012] Preferably, a tripod mounting plate is installed on the outer ring of the bearing by a plurality of bolts evenly spaced around the slewing shaft of the slewing bearing. The slewing tripod is detachably mounted on the tripod mounting plate. Two parallel connecting plates are arranged on the upper end face of the tripod mounting plate. The slewing tripod includes a tripod base plate and two square tubes fixed to the lower end face of the tripod base plate and connected to the two connecting plates. The square tubes are connected to the connecting strip plates by a plurality of bolts evenly spaced along the length of the connecting strip plates.

[0013] The fit between the square tube and the connecting strip plate enables rapid positioning in the width direction, and then a stable connection between the two is achieved by inserting bolts, making the operation simple and convenient.

The upper ends of the two triangular plates are connected to the hinge seat two via a hinge shaft, and the hinge seat three is located near the lower end of the triangular plates. The arrangement of each hinge seat makes the force applied and received by the steering assembly and lifting assembly more stable when adjusting the cable delivery.

[0015] Preferably, the conveyor module mounting frame includes a module mounting part and detachable cable inlet arms and cable outlet arms mounted at both ends of the module mounting part. The module mounting part is formed with an upward-opening mounting groove for mounting the cable conveyor. The cable inlet arm and the module mounting part are connected by a detachable component.

[0017] The connection method between the cable entry arm or cable exit arm and the module mounting part enables rapid positioning in four directions using the U-shaped frame and positioning plate, ensuring fast, efficient and accurate connection. On the other hand, it enables surface stress distribution, reducing the lateral shear of the bolts, making the connection more stable and having better connection strength.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] Example 1 This embodiment discloses a cable mounting device for underground utility tunnels, such as... Figures 1-10 As shown, this device enables the installation of 500kV large-section cables in confined spaces such as cable tunnels and municipal utility tunnels. The installation process is automated and requires no manual lifting, ensuring the safe installation of cables in urban underground utility tunnels. The cable installation device in this embodiment has a lifting capacity of at least 0.8 tons, a maximum lifting height of at least 2.5 meters, and a lateral cable pushing path of at least 1.5 meters. It also possesses the ability to move, turn, and adjust the direction and height of cable installation, making it flexibly applicable to the installation of large-section cables in such confined spaces.

[0031] Specifically, it includes a mobile chassis mechanism 1 and a detachable attitude adjustment mechanism 2 mounted on the mobile chassis mechanism 1; wherein, the mobile chassis mechanism 1 includes a chassis frame 101, the chassis frame 101 includes a mobile frame 102 and a support frame 103 that are detachably connected from the top and bottom, and the support frame 103 is provided with a mounting position for mounting the cable conveying module 3; the mobile frame 102 includes four support legs 104 and four drive wheels 105 respectively provided at the four support legs 104, and four independent drive components 106 for controlling the movement of the four drive wheels 105 respectively at the four support legs 104; The mobile chassis mechanism 1 is controlled by four independent drive wheels 105. The independent drive assembly 106 includes a drive motor 131 and a worm gear reducer 132 connected to the drive motor 131. The worm gear reducer 132 is connected to the drive wheels 105.

[0032] It can realize the forward, backward and in-place turning functions of cable racking equipment. When turning in place, the drive wheels on different sides can be controlled to move in opposite directions and at different speeds to achieve rotation in place. This allows the entire racking device to move flexibly in the pipe gallery or tunnel, and better realize cable racking construction.

[0033] The attitude adjustment mechanism 2 includes a conveying module mounting frame 201 for mounting the cable conveying module 3, and also includes a lifting assembly 204 and a steering assembly 205 that can adjust the cable conveying height and the cable conveying direction respectively. The lifting assembly 204 is detachably mounted on the steering assembly 205, and the conveying module mounting frame 201 is detachably mounted between the lifting assembly 204 and the steering assembly 205. The lifting assembly 204 and the steering assembly 205 enable adjustments to the height and width of the cable transport corridor, allowing for optimal cable mounting angles and ensuring both construction efficiency and safety.

[0034] The conveyor module mounting frame 201 includes a module mounting part 220 and detachable cable inlet arms 221 and cable outlet arms 222 mounted at both ends of the module mounting part 220. The module mounting part 220 forms an upward-opening mounting groove 223, in which a cable conveyor is installed. In this embodiment, the cable conveyor is driven by a dual-motor track chain plate to provide axial driving force for the cable and simultaneously provides forward power for the entire vehicle. When v1=v2*Cosθ*Cosα, the cable conveying speed is consistent with the trolley's moving speed and there is no slippage. In the formula, the forward moving speed of the trolley is v1, the axial conveying speed of the cable is v2, the angle between the axial direction of the cable and the vertical direction is θ, and the rotation angle of the bottom turntable is α.

[0035] The cable mounting device in this embodiment consists of multiple modular components, which are stably connected by detachable connections. Before construction, the mobile chassis mechanism 1, attitude adjustment mechanism, conveyor module mounting frame 201, and cable conveyor can be transported to the utility tunnel or tunnel respectively. Due to the excessive length of the conveyor module mounting frame 201, its cable entry arm 221 and cable output arm 222 can also be transported separately and assembled in the utility tunnel or tunnel. In addition, since the support frame 103 and the mobile frame 102 of the mobile chassis mechanism 1 can be separated, the lifting component 204 and the steering component 205 can be pre-installed on the mobile frame 102 during assembly. This avoids the cumbersome and time-consuming assembly steps of flange connection between the steering component 205 and the mobile frame 102 in the tunnel or utility tunnel, and realizes the rapid assembly of the mounted equipment in the tunnel or utility tunnel. This method of assembling equipment directly in narrow spaces without overall hoisting effectively solves the problem of inconvenient equipment hoisting in narrow spaces, making it more flexible and convenient to use.

[0036] This embodiment also provides a specific structure of the mobile chassis mechanism 1, wherein the mobile frame 102 includes four support legs 104 and four drive wheels 105 respectively disposed on the four support legs 104. Four independent drive components 106 are disposed on the four support legs 104 for controlling the movement of the four drive wheels 105 respectively. A drive component mounting plate 130 is provided on the lower end face of the support leg 104, and the independent drive components 106 are fixed on the drive component mounting plate 130.

[0037] The movable frame 102 is detachably connected to the support frame 103, and the connection is provided with a positioning component 107 and a fixing component 108. The movable frame 102 also includes a movable frame crossbeam 109 connected between two legs 104 along the length direction and a movable frame longitudinal beam 110 connected between two legs 104 along the width direction. The upper end of the legs 104 protrudes from the movable frame longitudinal beam 110 and forms a positioning element 111.

[0038] The support frame 103 includes a rectangular frame and a support plate 112 disposed in the middle of the rectangular frame. The upper end face of the support plate 112 forms an installation position. The rectangular frame includes two support frame crossbeams 113 and two support frame longitudinal beams 114. The connection between the support frame crossbeams 113 and the support frame longitudinal beams 114 is connected by a rectangular frame. The rectangular frame is configured to be a positioning element 115 that can be fitted onto the positioning element 111. The positioning element 111 and the positioning element 115 together constitute the positioning assembly 107. When the positioning element 115 is fully fitted onto the positioning element 111, the support frame longitudinal beam 114 is supported on the upper surface of the movable frame longitudinal beam 110.

[0039] In this embodiment, both the support frame 103 and the movable frame 102 are welded from square tubes 215, which has good structural strength. The positioning component 107 enables the support frame 103 to be quickly positioned on the movable frame 102. Simply place the support frame 103 on the movable frame 102 from top to bottom, and the positioning component 2 115 is aligned with the positioning component 111 and fitted onto the positioning component 111 to complete the pre-fixation between the movable frame 102 and the support frame 103. Under the gravity of the movable frame 102 and the equipment on it, the pre-fixation of the two has a certain degree of stability.

[0040] After pre-fixing, it is further fixed by fixing component 108. Fixing component 108 eliminates the traditional bolt fixing method, eliminating the need for bolts to be inserted and tightened one by one. Instead, it achieves quick fixing through snap-on fasteners. This fixing method also enables quick release of the fastener, allowing for quick assembly and disassembly between the mobile chassis mechanism 1 and the upper posture adjustment mechanism 2 in the equipment. This improves the efficiency of assembly and disassembly in narrow spaces and reduces the construction time for workers in that space.

[0041] Specifically, the fixing component 108 includes a first fixing member 116 and a second fixing member 117 that cooperates with and corresponds one-to-one with the first fixing member 116. Multiple fasteners 116 are installed on the outer side of the longitudinal beam 114 of the support frame and on the outer side of the positioning component 115. Fasteners 117 are installed on the outer side of the longitudinal beam 110 of the movable frame and on the outer side of the support leg 104. Fixture 116 includes a hook 118, and fixture 217 includes a hanging ring 119 that can be hooked onto the hook 118.

[0042] The second fixing component 117 includes a fixing plate 120 fixedly installed on the longitudinal beam 110 or the support leg 104 of the movable frame. A hinge plate 121, which is perpendicular to the fixing plate 120 and is wider at the top and narrower at the bottom, is installed on the fixing plate 120. A handle 122 is hinged to the upper end of the hinge plate 121. The upper end of the handle 122 is hinged to the upper and lower ends of the hinge plate 121 to form a grip. A pivot 123 is passed through the middle of the handle 122. One end of the hanging ring 119 is installed on the pivot 123, and the other end can be hung on the hook 118.

[0043] The second fixing component 117 also includes a limiting component that keeps the hanging ring 119 continuously hooked on the hook 118. The limiting component includes a fixing shaft 124 fixed on the handle 122. The hinge point of the hinge plate 121 and the fixing shaft 124 are distributed on the upper and lower sides of the rotating shaft 123. A limiting plate 125 and a torsion spring 126 connected to the limiting plate 125 are installed on the fixed shaft 124. The lower end of the hinge plate 121 is provided with a downwardly protruding limiting plate 127. The end of the limiting plate 125 facing the limiting plate 127 is provided with an upward-opening limiting groove 128. Under the action of the torsion spring 126, the limiting plate 127 can move towards the limiting plate 127 and be held in place within the limiting groove 128. The setting of the limiting plate 127 and the limiting groove 128 can further ensure the stability of the fixing assembly 108 in the fixed state and prevent the hanging ring 119 from moving upward and disengaging during operation.

[0044] During operation, simply align the hanging ring 119 with the hook 118 and hang it on the hook 118. Then, press down on the handle 122. As the gripping part of the handle 122 moves downward, it will cause the hanging ring 119 to press down on the hook 118. At the same time, it will cause the limiting piece 125 to move towards the limiting plate 127, so that the limiting plate 127 is locked in the limiting groove 128 and held in this state by the torsion spring 126. This completes the fixing between the moving frame 102 and the support frame 103. To release the fixing, simply pull up the handle 122 to disengage the limiting groove 128 from the limiting plate 127 and move the hanging ring 119 upward to separate the hook 118 from the hanging ring 119. The operation is simple and convenient, and it can achieve quick assembly and disassembly between the moving frame 102 and the support frame 103.

[0045] In addition, in this embodiment, both ends of the rotating shaft 123 protrude from the outer side of the handle 122 and are provided with hanging ring connection holes. The hanging ring 119 is constructed in the shape of a U-shaped rod, with both ends passing through the hanging ring connection holes. The outer surface of the hanging ring 119 is provided with external threads. The hanging ring 119 is connected to the rotating shaft 123 by threads, and nuts distributed on both sides of the rotating shaft 123 are connected and fixed to the rotating shaft 123. The connection method of the hanging ring 119 on the rotating shaft 123 allows the position of the hanging ring 119 relative to the hook 118 to be adjusted as needed, so that it can be better hooked onto the hook 118.

[0046] This embodiment also provides a specific structure of the attitude adjustment mechanism 2, including a conveying module mounting frame 201 for mounting the cable conveying module 3. The length direction of the conveying module mounting frame 201 is the conveying direction of the cable conveying module 3. The lower end surface of the conveying module mounting frame 201 is provided with a hinge seat 1 202 and a hinge seat 203 spaced apart along the length direction. It also includes a lifting assembly 204 and a steering assembly 205 that can adjust the cable delivery height and the cable delivery direction respectively; the steering assembly 205 includes a slewing bearing 206 and a slewing tripod 207 mounted on the slewing bearing 206 and capable of rotating under the action of the slewing bearing 206, one end of the slewing tripod 207 being hinged to the hinge seat 202. The lifting assembly 204 includes a lifting hydraulic cylinder 208 disposed at the other end of the rotary tripod 207. One end of the lifting hydraulic cylinder 208 is hinged to the rotary tripod 207, and the other end is hinged to the hinge seat 203. During the extension and retraction of the lifting hydraulic cylinder 208, it can drive the conveying module mounting frame 201 to rotate around the hinge point of the hinge seat 202.

[0047] The slewing bearing 206 includes an inner ring 209 and an outer ring 210. External teeth are formed on the outer surface of the outer ring 210. It also includes a rotary motor 211 for driving the slewing bearing 206. The rotary motor 211 is mounted on the conveyor module mounting bracket 201, and a drive gear 212 that meshes with the external teeth of the outer ring 210 is mounted on its output shaft. The rotary motor 211 is a worm gear reducer motor. A tripod mounting plate 213 is mounted on the outer ring 210 via multiple bolts evenly spaced around the slewing shaft 123 of the slewing bearing 206. A slewing tripod 207 is detachably mounted on the tripod mounting plate 213.

[0048] In this embodiment, the inner ring 209 of the bearing is fixed to the support plate 112 in the middle of the support frame 103 by bolts, and the outer ring 210 of the bearing is connected to the tripod mounting plate 213 by bolts. The rotation of the slewing tripod 207 and the components thereon is achieved through the slewing bearing 206. In addition, in order to achieve more precise and convenient adjustment in the width direction of the cable conveying duct, a position detection module is also provided. The position detection module includes multiple slotted photoelectric sensors arranged circumferentially around the slewing bearing 206. The tripod mounting plate 213 is provided with a sensing plate that cooperates with the slotted photoelectric sensors for detection. When the slewing motor 211 drives the slewing tripod 207 to rotate to the corresponding position, the rotation angle is controlled based on the sensing plate and the slotted photoelectric sensors at different positions, thereby accurately controlling the conveying direction of the upper conveying module mounting frame 201 and the cable conveyor on it.

[0049] In this embodiment, the upper end face of the tripod mounting plate 213 has two parallel connecting plates. The rotary tripod 207 includes a tripod base plate and two square tubes 215 fixed on the lower end face of the tripod base plate 217 and connected to the two connecting plates. The square tubes 215 and the connecting strip plate 214 are connected by a plurality of bolts evenly spaced along the length direction of the connecting strip plate 214.

[0050] The rotary tripod 207 and the tripod base plate 217 are connected by bolts. When connecting, the width direction can be positioned by first using the square tube 215 and the connecting strip plate 214. Then, the rotary tripod 207 is simply moved on the tripod mounting plate 213 so that the bolt holes on the connecting strip plate 214 and the square tube 215 are aligned, and the bolts can be inserted to achieve a stable connection between the two.

[0051] Two parallel triangle plates 216 are mounted on the upper surface of the tripod base plate 217 and are perpendicular to the tripod base plate 217. A reinforcing plate 218 is connected between the two triangle plates 216. The tripod base plate 217 is also provided with a hinge seat 219 located between the two triangle plates 216 and used to hinge with the end of the lifting hydraulic cylinder 208. The upper ends of the two triangle plates 216 are connected to the hinge seat 203 through a hinge shaft. The hinge seat 219 is located near the lower end of the triangle plates 216.

[0052] In this embodiment, the conveyor module mounting frame 201 includes a module mounting section 220 and detachable cable inlet arms 221 and cable outlet arms 222 mounted at both ends of the module mounting section 220. The module mounting section 220 has an upward-opening mounting groove 223 for mounting a cable conveyor. The module mounting section 220 is a frame structure composed of multiple square tubes 215. Hinges 1 202 and 203 are located at both ends of the module mounting section 220, so that the lifting hydraulic cylinder 208 has a better force application point and angle when adjusting the height of the conveyor module mounting frame 201.

[0053] The cable entry arm 221 and the module mounting part 220, as well as the cable output arm 222 and the module mounting part 220, are connected by a detachable component. The detachable component includes a limiting frame 224 that is disposed at the end of the module mounting part 220 and is configured as a rectangular frame. The ends of the cable entry arm 221 and the cable output arm 222 are provided with end plates 225 that are bolted to the limiting frame 224.

[0054] The conveying module mounting frame 201 is detachably connected in multiple sections, which can overcome the problem of inconvenience in hoisting a long frame into a narrow space during assembly. The upper surfaces of the cable inlet arm 221 and the cable outlet arm 222 are both flat, which can form a moving support surface for the cable. With the limiting parts at the ends of the cable inlet arm 221 and the cable outlet arm 222, the cable can be conveyed efficiently and accurately.

[0055] Specifically, the ends of the cable inlet arm 221 and the cable outlet arm 222 away from the module mounting part 220 are respectively provided with an input cable limiting member 228 and an output cable limiting member 229 for guiding the cable; The input cable limiting component 228 includes two horizontally rotating rollers 230 arranged parallel to each other, forming a cable input port 231 between the two rollers.
