Description

Technical Field

[0001] The present invention relates to a construction device for cable trench covers in a substation, and particularly to a storage mechanism for construction of cable trench covers in a substation. Background Art

[0002] For a newly built substation project, the number of cable trench covers ranges from hundreds to thousands. Usually, precast concrete covers are adopted. According to the standardized design requirements of the substation, the width of the cover is 500 mm, and the length varies according to the width of the cable trench. Common sizes are 1120, 1220, 1320, 1420, and 1520. The weight is between 70 kg and 100 kg. The covers are laid flat on the coping of two cable trenches, with each end extending 2 cm beyond the coping, as Figure 1 shown.

[0003] The traditional construction of cable trench covers mainly relies on manual installation. There is no special transportation tool for the covers from the storage yard to the operation point. A wheelbarrow is used to transport one cover at a time, and 2 - 3 people are required to cooperate during installation. On average, only 5 covers can be installed per hour. For example, a 220 kV conventional substation requires about 1400 covers on average, which requires more than 800 man - hours. This process is very labor - intensive.

[0004] In the prior art, mechanical grasping is also adopted. For example, in the Chinese invention patent application with the publication number CN 105398975 A and the patent name of Construction Device for Cable Trench Covers, a method of mechanically grasping the trench covers is given. Although it can solve the problems of labor cost and work efficiency during the disassembly of the trench covers, the trench covers are stacked without gaps after being grasped. Since the trench covers are relatively heavy, this placement method causes the lifting claws to be unable to grasp the trench covers during installation, and manual handling is still required. Therefore, it is necessary to propose a device that can facilitate continuous mechanical grasping, storage, and installation. Summary of the Invention

[0005] Aiming at the problems existing in the grasping of substation trench covers in the prior art, the present invention provides a storage device for assisting the installation of cable trench covers.

[0006] To solve the above - mentioned technical problems, the present invention is solved by the following technical solutions:

[0007] A storage mechanism for construction of cable trench covers includes a storage frame. The storage frame includes a storage part and a partition part. The storage part is a frame structure with a storage cavity formed in the middle. In the partition part, a plurality of partition racks are arranged evenly in the vertical direction. The partition racks can horizontally extend into the storage cavity and divide the storage cavity into a plurality of cover placement cavities in the vertical direction.

[0008] Preferably, the storage part includes a bottom frame. The bottom frame includes a bottom plate in an H shape. The bottom plate includes two long flat steels arranged in parallel with each other. A plurality of short flat steels are connected between the two long flat steels. At the edges of the two long flat steels, a U-shaped limiting plate perpendicular to the bottom plate is provided. The U-shaped limiting plates on both sides are arranged with their openings facing each other. The bottom plate and the U-shaped limiting plates on both sides together form a single-plate placement cavity for placing the bottom-layer cable trench covers. The setting of the bottom frame can make the entire storage frame structure more stable and have higher structural strength to ensure that it can store and transport multiple trench covers.

[0009] Preferably, the isolation part includes a plurality of isolation rack installation parts for installing isolation racks. The isolation rack installation part includes a guide rail with a guide rail groove formed inside. The isolation rack is installed on the guide rail. The isolation rack includes two isolation rods that are cross-rotationally connected to each other. Both isolation rods include a rotating shaft end that can rotate in the guide rail groove and a telescopic end that can extend into or withdraw from the storage cavity under the mutual rotation of the two isolation rods; the rotating shaft end of one of the isolation rods is fixed relative to the length direction of the guide rail, and the rotating shaft end of the other isolation rod can slide along the length direction of the guide rail. The structural form and operation of the isolation rack are relatively simple and convenient. After being unfolded, it can provide a relatively large supporting surface, and after being retracted, it does not affect the grasping of the lower-layer trench covers.

[0010] Preferably, the guide rail includes an outer side plate and an inner side plate that are parallel and vertically arranged. The guide rail groove is formed between the outer side plate and the inner side plate. The inner side plate is provided with an isolation rod sliding groove for the two isolation rods to pass through and slide along the length direction of the guide rail; the rotating shaft end that can slide along the length direction of the guide rail is provided with a latch and a latch spring connected to the end of the guide rail groove and axially arranged along the length direction of the guide rail. The latch spring has a tendency to drive the isolation rod to withdraw from the storage cavity. The outer side plate is provided with a latch slot for the latch to pass through and a latch lock provided at the end of the latch slot away from the latch spring. When the latch is latched on the latch lock, the isolation rod is fully unfolded and extends into the storage cavity. The setting of the latch spring can realize that after the upper-layer trench cover is taken out, the isolation rack automatically retracts into the isolation part, and then realize the continuous grasping and installation of the trench cover by the lifting claw from top to bottom.

[0011] Preferably, the latch includes a connecting part whose end is connected to the rotating shaft end of the isolation rod. A limiting rod is rotatably connected to the end of the connecting part away from the isolation rod. The latch lock is in an L shape. When the limiting rod rotates into the L-shaped groove of the latch part, it is in a vertical state and constitutes a sliding limit for the isolation rod in the guide rail groove. The latch lock and latch with this kind of structure can make the operations of limiting or releasing the limit of the latch very simple and convenient, meeting the requirements of rapid construction on the construction site.

[0012] Preferably, a rotating shaft and a mutually cooperating rotating groove are provided at the intersection of the two isolation rods, and the two isolation rods rotate relative to each other in the same horizontal plane under the action of the rotating groove and the rotating shaft. The rotation of the two isolation rods in the same horizontal plane enables the isolation frame to form a relatively large supporting surface for the trench cover plate, so as to ensure the stable support of the trench cover plate.

[0013] Preferably, the guide rail further includes an upper top plate and a lower top plate. Ball bearings are provided on the upper and lower end faces of the rotating shaft end that can slide along the length direction of the guide rail, and the ball bearings can respectively be on the upper top plate and the lower top plate. The setting of the ball bearings can make the isolation rod slide more smoothly in the guide rail groove, and also reduce the frictional resistance when the isolation rod automatically resets subsequently.

[0014] Preferably, the storage part further includes columns vertically arranged on the bottom frame. At the upper end of the columns, there are a fixed cross beam perpendicular to each other and a removable movable cross beam. The length direction of the fixed cross beam is perpendicular to the telescopic direction of the isolation rod, and the length direction of the movable cross beam is the same as the telescopic direction of the isolation rod. The settings of the movable cross beam and the fixed cross beam can effectively strengthen the structural stability of the storage frame to ensure the structural strength of the entire storage frame when transporting multiple layers of trench cover plates.

[0015] Preferably, there are four columns, and each column is a long strip plate with an L-shaped cross section. The four columns can jointly perform horizontal limiting on the trench cover plates in the storage cavity. The structural form of the columns can achieve the horizontal limiting of the trench cover plates in the storage frame to ensure the stability during the transportation process.

[0016] Preferably, on the adjacent columns connecting the movable cross beam, there are respectively a hinge shaft and a clamping groove with an upward opening. One end of the movable cross beam is hinged to the hinge shaft of one column, and the other end is clamped into the clamping groove of the adjacent column from top to bottom. This method realizes the installation of the movable cross beam, making its installation and disassembly very convenient and minimizing the impact on the construction efficiency as much as possible.

[0017] Preferably, there are multiple storage frames, and walking wheels are provided at the bottom of each. Connecting members are provided between adjacent storage frames. The connecting members include hooks and hanging rings respectively arranged at both ends of the storage frame along the telescopic direction of the isolation rod. The settings of the hooks and the hanging rings can connect multiple storage frames into a whole, realizing the one-time transportation of multiple storage frames and reducing the number of times of transporting the trench cover plates.

[0018] Preferably, on the lower end face of the bottom frame and on both sides along the telescopic direction of the isolation rod, there are side limiting plates, and a forklift limiting part is formed between the two side limiting plates. The side limiting plates can limit the storage frame on the cover plate installation vehicle, facilitating the subsequent grasping and installation of the trench cover plates.

[0019] A cable trench cover plate construction device includes the aforementioned storage mechanism for cable trench cover plate construction.

[0020] Due to the adoption of the above technical solution, the present invention has remarkable technical effects:

[0021] The present invention can effectively solve the problem that the lifting claws cannot grasp the cable trench covers when the cable trench covers are stacked without gaps, and it can realize continuous mechanical grasping, storage and installation of the cable trench covers, with high construction efficiency.

[0033] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0034] Embodiment 1

[0035] A cable trench cover construction device, as Figures 1 - 6As shown, it includes a walking mechanism 200 capable of walking on the upper surface of the trench cover 100, the walking mechanism 200 includes a gantry 201, a fork frame 202 and a mounting frame 203, one end of the fork frame 202 is arranged at the lower end of the gantry 201, and the other end extends along the walking direction of the walking mechanism 200, the walking mechanism 200 also includes an operation display screen 215 arranged on the gantry 201 and a control handle 216 arranged at the rear end of the gantry 201, and a motor assembly 217 and a power wheel 218 are provided at the control handle 216.

[0036] The walking mechanism 200 in this embodiment can be an electric transport vehicle in the prior art, wherein how the control handle 216 controls the walking of the walking mechanism 200 and how the gripping mechanism 400 thereon is controlled by the control handle 216 and the operation display screen 215 are all control technologies that the existing electric transport vehicles already have.

[0037] In this embodiment, the traveling mechanism 200 is provided with a storage mechanism 300 for storing the trench cover 100 and a grabbing mechanism 400 for grabbing the trench cover 100. The storage mechanism 300 includes a storage frame 301, and the grabbing mechanism 400 includes a grabbing portion 401 that can make linear reciprocating motion along the traveling direction of the traveling mechanism 200. The grabbing portion 401 can move above the storage frame 301 and move in the vertical direction to grab the trench cover 100 in the storage frame 301 or store the trench cover 100 in the storage frame 301.

[0038] This linear reciprocating motion method is used to grab and install the trench cover 100 from the storage frame 301, or the trench cover 100 is removed from the cable trench and stored in the storage frame 301. Compared with the rotation method, the construction work will not occupy the space outside the cable trench, and will not be restricted by the numerous structural supports on the site where the cable trench is located. This method is more flexible and convenient.

[0039] In this embodiment, the mounting frame 203 is horizontally arranged with one end arranged on the upper end of the door frame 201 , and the other end extends in the same direction as the fork frame 202 . The storage frame 301 is arranged on the fork frame 202 , and the grabbing mechanism 400 is arranged on the mounting frame 203 .

[0040] The fork frame 202 includes two forks 204 and a fork frame crossbeam connected to the front end of the two forks 204 at both ends. The upper end surface of the fork frame crossbeam is flush with the upper end surface of the forks 204. A fixed limit plate 205 is provided on the upper end surface of the two forks 204, and a retractable movable limit plate 206 is provided on the fork frame crossbeam. The fixed limit plate 205 and the movable limit plate 206 together constitute a limit for the storage frame 301 in the walking direction.

[0041] Among them, a limiting plate mounting housing 207 with an upper end surface height less than or equal to the upper end surface height of the forklift carriage crossbeam is provided on the front end surface of the forklift carriage crossbeam. An accommodation cavity 208 with an upper opening for mounting the movable limiting plate 206 is formed inside the limiting plate mounting housing 207. A limiting plate spring 209 for driving the upper end of the movable limiting plate 206 to extend above the upper end surface of the forklift carriage crossbeam is provided in the accommodation cavity 208. Under the action of the limiting plate spring 209, the rear end surface of the movable limiting plate 206 constitutes a limiting surface for limiting the storage frame 301. The upper end surface of the movable limiting plate 206 is an inclined surface inclined towards the front end of the forklift carriage 202. A pedal 210 capable of driving the movable limiting plate 206 to descend and retract into the accommodation cavity 208 is connected to the front end surface of the movable limiting plate 206.

[0042] During operation, the forklift 204 drives into the bottom of the storage frame 301. In this embodiment, side limiting plates 341 are provided on both sides of the lower end surface of the storage frame 301. A forklift limiting portion is formed between the two side limiting plates 341. So that when the trench cover plate 100 is installed subsequently, the storage frame 301 can be stably located at the forklift 204 of the cover plate installation vehicle, and the storage frame 301 can be positioned on the cover plate installation vehicle, making the central axis of the storage frame 301 coincide with the central axis of the cover plate installation vehicle, so as to facilitate the subsequent grabbing, laying or storage by the lifting claws 403, and facilitate the mechanized construction of the trench cover plate 100.

[0043] Then, as the storage frame 301 enters the forklift 204 and a force is applied to the upper inclined surface of the movable limiting plate 206, the movable limiting plate 206 is pressed into the accommodation cavity 208. At this time, the storage frame 301 can continue to move towards the rear end of the forklift 204 on the forklift 204 until the rear end of the storage frame 301 abuts against the fixed limiting plate 205 at the rear end of the forklift 204. At this time, the front end surface of the storage frame 301 is separated from the movable limiting plate 206. The movable limiting plate 206 extends out of the accommodation groove under the action of the limiting plate spring 209, and the rear end surface of the movable limiting plate 206 and the front end surface of the fixed limiting plate 205 jointly constitute a limit for limiting the storage frame 301, and then cooperate with the side limiting plates 341 on the storage frame 301 to jointly limit the storage frame 301 on the forklift 204 to ensure the accuracy of the position of the storage frame 301 on the forklift 204 and the stability during the movement of the forklift 204.

[0044] When it is necessary to remove the storage frame 301 from the forklift 204, only by stepping on the pedal 210 with the foot, the movable limiting plate 206 can be retracted into the accommodation cavity 208 against the elastic force of the limiting plate spring 209, and then the forklift 204 can be withdrawn from the bottom of the storage frame 301.

[0045] In this embodiment, the mounting bracket 203 is of a rectangular frame structure. On both inner walls of the mounting bracket 203, there are mounting bracket sliding grooves 211 whose length direction is set along the extending direction of the mounting bracket 203. The mounting bracket sliding groove 211 is a U-shaped groove opening towards the middle of the mounting bracket 203. The grasping mechanism 400 includes a sliding plate 402 whose two ends are respectively arranged in the mounting bracket sliding grooves 211 on both sides and can slide along the mounting bracket sliding grooves 211. In order to make the sliding of the sliding plate 402 smoother, rollers 214 cooperating with the end of the sliding plate 402 are arranged on the bottom surface of the mounting bracket sliding groove 211, so that the sliding plate 402 can slide through the rollers 214 to reduce friction.

[0046] In this embodiment, the grasping part 401 is connected to the lower end surface of the sliding plate 402 through a longitudinal telescopic mechanism. The grasping part 401 includes two lifting claws 403 that can move towards or away from each other in a horizontal plane along a direction perpendicular to the sliding direction of the sliding plate 402. Among them, a driving connecting rod 212 is arranged on the mounting bracket 203, and a first hydraulic push rod 213 for driving the sliding plate 402 to slide is fixed on the driving connecting rod 212 and connected to the sliding plate 402. The grasping part 401 includes a grasping frame. A second hydraulic push rod 404 for driving the lifting claws 403 to move is arranged on the grasping frame. A guide rod 405 whose axis is parallel to the axis of the second hydraulic push rod 404 is also arranged on the grasping frame, and the end of the guide rod 405 is connected to the lifting claws 403.

[0047] The longitudinal telescopic mechanism includes two telescopic frames 406 respectively arranged on both sides of the sliding plate 402. The telescopic frame 406 includes a link frame 407 composed of multiple mutually cross-hinged connecting rods, and also includes an upper telescopic frame slide rail 408 and a lower telescopic frame slide rail 409 respectively arranged at the upper and lower ends of the telescopic frame 406. When the connecting rod rotates around the hinge point, the link frame 407 can extend or shorten, and the upper and lower ends of the link frame 407 are respectively slidably connected in the upper telescopic frame slide rail 408 and the lower telescopic frame slide rail 409.

[0048] In addition, the connecting rod includes multiple mutually parallel outer connecting rods 410 and multiple mutually parallel inner connecting rods 411. The outer connecting rods 410 and the inner connecting rods 411 are cross-hinged inside and outside, and hinge points are arranged at both ends and the middle of each outer connecting rod 410 and inner connecting rod 411. The link frame 407 is provided with inner connecting rods 411 and outer connecting rods 410 to form a double-layer telescopic link frame 407, and is hinged through multiple hinge points, so that it has better structural strength and structural stability, effectively improving the bearing capacity and operation stability of the telescopic frame 406.

[0049] A servo motor 412 for driving the synchronous expansion and contraction of the expansion frames 406 on both sides of the sliding plate 402 is fixed on the sliding plate 402. Pulley 413 is provided on both sides of the sliding plate 402, and a wire rope 414 with one end cooperatively connected to the motor shaft of the servo motor 412 and the other end connected to the lower expansion frame slide rail 409 is provided on each of the pulleys 413 on both sides.

[0050] During the installation operation of the trench cover plate 100, first push the sliding plate 402 through the first hydraulic push rod 213, so that the grasping part 401 moves above the storage frame 301. Then start the servo motor 412. The servo motor 412 drives the wire ropes 414 on both sides to simultaneously pull or lower the expansion frames 406, and then realizes the synchronous expansion and contraction of the expansion frames 406 on both sides, so that the grasping part 401 moves downward to grasp the trench cover plate 100 in the storage frame 301. Drive the lifting claws 403 to run to the lower parts at both ends of the trench cover plate 100 through the second hydraulic push rod 404. Then drive the servo motor 412 to run in the reverse direction, drive the grasping part 401 to drive the trench cover plate 100 to move upward. Then push the sliding plate 402 through the first hydraulic push rod 213 to make the grasping part 401 grasping the trench cover plate 100 run to the installation station for installing the trench cover plate 100. Finally, put down the trench cover plate 100 to complete the installation of the trench cover plate 100. The reverse operation can be carried out during the disassembly process. The whole process can be controlled by operating the display screen 215 and the control handle 216. And a laser displacement sensor is arranged on the traveling mechanism 200. Through the display screen operation control system, the laser displacement sensor is aligned with the cable trench coping edge line, the traveling mechanism 200 is controlled to travel along the cable trench central axis, and the laser displacement sensor is used to identify the position where the height difference between the installed cover plate and the cable trench coping suddenly changes, so as to accurately install the trench cover plate 100.

[0051] In addition, in this embodiment, a storage mechanism for storing the trench cover plates as described above is also provided, that is, a storage mechanism for cable trench cover plate construction, as Figures 7 - 11 shown. It includes a storage frame 301. The storage frame 301 includes a storage part 302 and an isolation part 303 arranged on one side of the storage part 302. The storage part 302 is a frame structure with a storage cavity 305 formed in the middle. A plurality of isolation frames 304 are uniformly arranged in the vertical direction in the isolation part 303. When isolating the storage cavity 305, the isolation frames 304 can horizontally extend into the storage cavity 305 and divide the storage cavity 305 into a plurality of cover plate placement cavities in the vertical direction. When the storage cavity 305 does not need to be isolated, they contract in the isolation part 303.

[0052] Through the arrangement of the isolation frame 304, it is possible to achieve one layer of trench cover plates 100 and one layer of isolation frame 304, so that although the trench cover plates 100 are still stacked in a space-saving manner in the storage part 302, there is a gap between the upper-line trench cover plates 100 for the lifting claws 403 to extend into the bottom of the trench cover plates 100, facilitating the grasping of the trench cover plates 100 by the lifting claws 403.

[0053] In this embodiment, the storage part 302 includes a bottom frame 306. The bottom frame 306 includes a bottom plate 307 in an H shape. The bottom plate 307 includes two parallel long flat steels 308. A plurality of short flat steels 309 are connected between the two long flat steels 308. At the edges of the two long flat steels 308, a U-shaped limiting plate 310 perpendicular to the bottom plate 307 is provided. The openings of the U-shaped limiting plates 310 on both sides are arranged opposite to each other. The bottom plate 307 and the U-shaped limiting plates 310 on both sides together form a single-plate placement cavity 311 for placing the bottommost trench cover plates 100.

[0054] The arrangement of the bottom frame 306 can, on the one hand, limit the bottommost trench cover plates 100, enabling them to move only in the vertical direction and not in the horizontal direction, ensuring the storage stability of the trench cover plates 100 during the transportation of the storage frame 301. On the other hand, it can effectively enhance the bearing capacity of the bottom of the storage part 302. Although the upper trench cover plates 100 are isolated by the isolation frame 304, their final weight still falls on the bottom frame 306. Compared with placing the trench cover plates 100 only through the isolation frame 304 at the bottom, the form of setting the bottom frame 306 to place the bottommost trench cover plates 100 can make the entire storage part 302 have a stronger bearing capacity, and the upper and lower trench cover plates 100 in the storage part 302 can be stably stored.

[0055] In addition, the bottom plate 307 of the bottom frame 306 in this embodiment is in an H shape, making the two ends of the bottom plate 307 form an inwardly concave structure. Thus, when the bottommost trench cover plates 100 are placed in the single-plate placement cavity 311, the two ends of the trench cover plates 100 will extend out of the ends of the bottom plate 307, enabling the lifting claws 403 to grasp the two ends of the bottommost trench cover plates 100.

[0056] In this embodiment, the isolation part 303 includes a plurality of isolation rack mounting parts 312 for mounting the isolation rack 304. The isolation rack mounting part 312 includes a guide rail 314 with a guide rail groove 313 formed inside. The isolation rack 304 is mounted on the guide rail 314. The isolation rack 304 includes two isolation rods 315 that are cross-rotationally connected to each other. Both isolation rods 315 include a rotating shaft end 316 that can rotate within the guide rail groove 313 and a telescopic end 317 that can extend into or withdraw from the storage cavity 305 under the mutual rotation of the two isolation rods 315. The rotating shaft end 316 of one of the isolation rods 315 is fixed relative to the length direction of the guide rail 314, and the rotating shaft end 316 of the other isolation rod 315 can slide along the length direction of the guide rail 314. When the isolation rack 304 needs to be deployed or retracted, by controlling the movable isolation rod 315 to slide its end within the guide rail groove 313, the two isolation rods 315 can rotate towards or away from each other, thereby realizing the deployment or retraction of the two cross isolation rods 315.

[0057] In order to ensure that the two isolation rods 315 are on the same horizontal plane, a rotating shaft 327 and a mutually cooperating rotating groove 328 are provided at the intersection of the two isolation rods 315. The two isolation rods 315 rotate relative to each other in the same horizontal plane under the action of the rotating groove 328 and the rotating shaft 327, so that the two isolation rods 315 can jointly support the trench cover plate 100, and a wider and larger support surface can be formed on the lower surface of the trench cover plate 100 after deployment, so as to realize more stable support for the trench cover plate 100.

[0058] In this embodiment, the guide rail 314 includes an outer side plate 318 and an inner side plate 319 that are parallel and vertically arranged. A guide rail groove 313 is formed between the outer side plate 318 and the inner side plate 319. The inner side plate 319 is provided with a sliding groove for the isolation rod 315 through which the two isolation rods 315 pass and slide along the length direction of the guide rail 314. The rotating shaft end 316 that can slide along the length direction of the guide rail 314 is provided with a bolt 321 and a bolt spring 322 connected to the end of the guide rail groove 313 and axially arranged along the length direction of the guide rail 314. The bolt spring 322 has a tendency to drive the isolation rod 315 to withdraw from the storage cavity 305. The outer side plate 318 is provided with a bolt groove 323 for the bolt to pass through and a bolt lock 324 arranged at the end of the bolt groove 323 away from the bolt spring 322. When the bolt 321 is latched on the bolt lock 324, the isolation rod 315 is fully deployed and extends into the storage cavity 305.

[0059] Among them, the bolt 321 includes a connecting portion 325 whose end is connected to the rotating shaft end 316 of the isolation rod 315. A limiting rod 326 is rotatably connected to the end of the connecting portion 325 away from the isolation rod 315. The bolt lock 324 is L-shaped. When the limiting rod 326 rotates into the L-shaped groove of the bolt 321, it is in a vertical state and constitutes a sliding limit for the isolation rod 315 within the guide rail groove 313.

[0060] In addition, in order to make the isolation rod 315 move more smoothly within the guide rail groove 313, the guide rail 314 further includes an upper top plate 329 and a lower top plate 330. Ball bearings 331 are provided on the upper and lower end faces of the rotating shaft end 316 that can slide along the length direction of the guide rail 314, and can respectively be on the upper top plate 329 and the lower top plate 330.

[0061] In this embodiment, the isolation rod 315 has a diameter of 2 cm and is made of polyurethane material. During operation, the isolation rod 315 is controlled by pulling the bolt 321. When in use, the bolt 321 is pulled, causing the isolation rod 315 to overcome the elastic force of the bolt spring 322. Eventually, the bolt 321 is pulled to the position of the bolt lock 324 and is limited, realizing the overall expansion limit of the isolation frame 304, and forming a 2 cm thick isolation plane space between the upper and lower adjacent trench covers 100.

[0062] When removing the trench cover 100, first unlock the bolt 321 and the bolt lock 324. At this time, under the pressure and frictional force of the upper and lower trench covers 100, the isolation frame 304 will not retract. When the upper trench cover 100 is removed, the isolation rod 315 will automatically retract into the isolation part 303 under the action of the bolt spring 322. This method enables all the bolts 321 and the bolt locks 324 to be released from the limit at one time when the trench cover 100 needs to be installed. Then, the trench covers 100 can be laid one by one through the lifting claws 403. During the laying process, after the upper trench cover 100 is removed, the corresponding lower isolation frame 304 will automatically retract, and the lifting claws 403 can directly grab the lower trench cover 100. During the whole process, there is no need for the operator to repeatedly unlock to remove the isolation frame 304, but the trench covers 100 can be continuously laid, effectively improving the installation efficiency of the trench covers 100.

[0063] In this embodiment, the storage part 302 further includes columns 332 vertically arranged on the bottom frame 306. The upper end of the column 332 is provided with a fixed cross beam 333 perpendicular to each other and a removable movable cross beam 334. The length direction of the fixed cross beam 333 is perpendicular to the telescopic direction of the isolation rod 315, and the length direction of the movable cross beam 334 is the same as the telescopic direction of the isolation rod 315.

[0064] Among them, there are four columns 332, and they are all long strip plates with an L-shaped cross section. The four columns 332 can jointly horizontally limit the trench covers 100 in the storage cavity 305.

[0065] On the adjacent columns 332 connecting the movable cross beam 334, a hinge shaft 335 and a clamping groove 336 with an upward opening are respectively provided. One end of the movable cross beam 334 is hinged to the hinge shaft 335 of one column 332, and the other end is clamped into the clamping groove 336 of the adjacent column 332 from top to bottom.

[0066] The settings of both the fixed cross beam 333 and the movable cross beam 334 can effectively improve the overall structural stability of the storage frame 301. At the same time, the four columns 332 are arranged in the shape of angle steel, which can effectively form the horizontal limit of the trench cover plate 100 within the storage frame 301, ensuring that the trench cover plate 100 will not fall off during the transportation of the storage frame 301.

[0067] During storage, the movable cross beam 334 is installed on the adjacent columns 332. When operation is required, the movable cross beam 334 is disengaged from the clamping groove 336 to release the restriction at the end of the movable cross beam 334 of the storage frame, enabling the lifting claw 403 to enter the interior of the storage frame 301 from top to bottom to grasp the trench cover plate 100 at the lower part of the storage frame 301.

[0068] There are multiple storage frames 301, and walking wheels 337 are provided at the bottom of each of them. A connecting member 338 is provided between adjacent storage frames 301. The connecting member 338 includes a hook 339 and a hanging ring 340 respectively arranged at both ends of the storage frame 301 along the telescopic direction of the isolation rod 315. The settings of the hook 339 and the hanging ring 340 can achieve the overall transportation after connecting multiple storage frames 301. Since the trench cover plate 100 is relatively heavy, it is not appropriate to set a large number of trench cover plates 100 on one storage frame 301. However, the number of trench cover plates 100 required during operation is relatively large. Therefore, adopting this form of connecting multiple storage frames 301 together can effectively reduce the transportation times of the storage frame 301.

[0069] On the lower end surface of the bottom frame 306 and on both sides along the telescopic direction of the isolation rod 315, side limiting plates 341 are provided. A forklift limiting part is formed between the two side limiting plates 341. So that when the trench cover plate 100 is to be installed subsequently, the storage frame 301 can be stably located at the forklift 204 of the cover plate installation vehicle, and the storage frame 301 can be positioned on the cover plate installation vehicle, making the central axis of the storage frame 301 coincide with the central axis of the cover plate installation vehicle, so as to facilitate the subsequent grasping, laying or storage by the lifting claw 403, and facilitate the mechanized construction of the trench cover plate 100.

[0070] In summary, the above description is only the preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
