Description

Technical Field

[0001] This invention relates to a substation construction device, and more particularly to a cable trench cover construction device. Background Technology

[0002] A newly constructed substation project requires hundreds to thousands of cable trench covers, typically precast concrete slabs. According to standardized substation design requirements, the cover width is 500mm, and the length varies depending on the cable trench width. Common sizes include 1120mm, 1220mm, 1320mm, 1420mm, and 1520mm, with a weight between 70kg and 100kg. The covers are laid flat on the top of two cable trenches, extending 2cm beyond the top at each end. Figure 1 As shown.

[0003] Traditional trench cover installation relies mainly on manual labor. There are no dedicated transport vehicles for the covers from the storage yard to the work site; they are transported one at a time using wheelbarrows. Installation requires 2-3 people working together, and on average, only 5 covers can be installed per hour. For example, a 220kV conventional substation requires an average of about 1,400 covers, which takes more than 800 man-hours. This process is extremely wasteful of manpower.

[0004] Existing technologies also employ mechanical gripping, such as the Chinese invention patent application CN 105398975 A, entitled "Trench Cover Construction Device," which discloses a method for mechanically gripping trench covers. While this method can solve the problems of labor costs and work efficiency during trench cover dismantling, its hoisting mechanism uses a rotating method to deliver the trench cover to the storage location after gripping it. Since the cable trench site is filled with scaffolding structures, there is no space for the rotating mechanism to rotate. Therefore, this type of rotating hoisting mechanism is greatly limited in substation operations. Summary of the Invention

[0005] This invention addresses the problems existing in the construction of trench covers in the prior art by providing a cable trench cover construction device.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A cable trench cover construction device includes a traveling mechanism capable of walking on the surface of the trench cover. The traveling mechanism is equipped with a storage mechanism for storing the trench cover and a gripping mechanism for gripping the trench cover. The storage mechanism includes a storage frame, and the gripping mechanism includes a gripping part capable of linear reciprocating motion along the traveling direction of the traveling mechanism. The gripping part can move above the storage frame and move vertically to grip the trench cover in the storage frame or store the trench cover in the storage frame.

[0008] Both the storage frame and the gripping device are mounted on the walking mechanism, and the two can install and remove the trench cover through relative linear movement. This is not limited by other facilities set up at the cable trench construction site, and allows for convenient and flexible construction.

[0009] Preferably, the traveling mechanism includes a mast, a fork carriage, and a mounting frame. One end of the fork carriage is located at the lower end of the mast, and the other end extends along the traveling direction of the traveling mechanism. The mounting frame is horizontally arranged with one end located at the upper end of the mast and the other end extending in the same direction as the fork carriage. The storage frame is located on the fork carriage, and the gripping mechanism is located on the mounting frame.

[0010] Preferably, the fork carriage includes two forks and a fork carriage crossbeam connected to the front ends of the two forks respectively. Fixed limiting plates are provided on the upper surfaces of the two forks, and retractable movable limiting plates are provided on the fork carriage crossbeam. The fixed limiting plates and movable limiting plates together constitute the limiting of the storage frame in the direction of travel. The fixed limiting plates and movable limiting plates can effectively ensure the operational stability of the storage frame on the forks.

[0011] Preferably, the front end face of the fork carriage beam is provided with a limiting plate mounting housing with an upper end face height less than or equal to the upper end face height of the fork carriage beam. The limiting plate mounting housing has an opening at the upper end for mounting a movable limiting plate. The accommodating cavity is provided with a limiting plate spring that drives the upper end of the movable limiting plate to extend above the upper end face of the fork carriage beam. Under the action of the limiting plate spring, the rear end face of the movable limiting plate forms a limiting surface that limits the storage frame. The upper end face of the movable limiting plate is an inclined surface that tilts towards the front end of the fork carriage. A pedal that can drive the movable limiting plate to descend and retract into the accommodating cavity is connected to the front end face of the movable limiting plate.

[0012] The structure and installation method of the movable limit plate make it easy to limit the storage frame and also easy to release the limit when the storage frame is removed. The operation is very convenient and can be completed independently by one operator.

[0013] Preferably, the mounting frame is a rectangular frame structure, and the inner walls on both sides of the mounting frame are provided with mounting frame sliding grooves arranged along the length direction of the mounting frame. The gripping mechanism includes a sliding plate with both ends respectively arranged in the mounting frame sliding grooves on both sides and capable of sliding along the mounting frame sliding grooves. The gripping part is connected to the lower end surface of the sliding plate through a longitudinal telescopic mechanism. The gripping part includes two claws that can move towards each other or away from each other in the horizontal plane along the sliding direction perpendicular to the sliding plate.

[0014] Preferably, the mounting bracket is provided with a drive connecting rod, and a first hydraulic push rod is fixed on the drive connecting rod and connected to the sliding plate for driving the sliding plate to slide.

[0015] Preferably, the gripping unit includes a gripping frame, on which a second hydraulic push rod is connected to the lifting claw for driving the claw's movement. The gripping frame also has a guide rod whose axis is parallel to the axis of the second hydraulic push rod, with its end connected to the lifting claw. The guide rod allows the lifting claw to operate more accurately during the gripping process, achieving precise gripping of the trench cover and ensuring uniform force distribution on the gripping unit, thus providing a prerequisite for the stable and accurate installation of the trench cover.

[0016] Preferably, the longitudinal telescopic mechanism includes two telescopic frames respectively disposed on both sides of the sliding plate. Each telescopic frame includes a linkage frame composed of multiple intersecting and hinged connecting rods, and an upper telescopic frame slide rail and a lower telescopic frame slide rail respectively disposed at the upper and lower ends of the telescopic frame. When the connecting rods rotate around the hinge point, the linkage frame can extend or shorten. The upper and lower ends of the linkage frame are slidably connected within the upper and lower telescopic frame slide rails, respectively. The structural form of the telescopic frame gives it a good telescopic length, while also featuring simple structure and convenient assembly.

[0017] Preferably, the connecting rod includes multiple parallel outer connecting rods and multiple parallel inner connecting rods. The outer and inner connecting rods are hinged together, and each outer and inner connecting rod has hinge points at both ends and the middle. This structural form with inner and outer connecting rods improves the strength and stability of the telescopic frame and increases its load-bearing capacity.

[0018] Preferably, a servo motor is fixed on the sliding plate to drive the telescopic frames on both sides of the sliding plate to extend and retract synchronously. Each side of the sliding plate is equipped with pulleys, and each pulley has a wire rope with one end connected to the motor shaft of the servo motor and the other end connected to the slide rail of the lower telescopic frame. By using the servo motors to drive the wire ropes, the movement of the telescopic frames on both sides can be achieved, enabling synchronous extension and retraction of the two telescopic frames, resulting in better gripping of the trench cover.

[0019] Preferably, the mounting bracket sliding groove is a U-shaped groove opening towards the center of the mounting bracket, and a roller that mates with the end of the sliding plate is provided on the bottom surface of the mounting bracket sliding groove. The roller reduces friction during the movement of the sliding plate, making the sliding process more stable and smooth.

[0020] Preferably, the traveling mechanism also includes an operation display screen mounted on the gantry and a control handle mounted at the rear end of the gantry, with a motor assembly and a drive wheel located at the control handle.

[0021] This invention, by adopting the above technical solutions, has significant technical effects:

[0022] Compared to rotating or disassembling trench covers, this invention does not occupy the space outside the cable trench during construction, and is not restricted by the numerous supporting structures on the site of the cable trench, making construction more flexible and convenient.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] A cable trench cover construction device, such as Figures 1-6As shown, the device includes a traveling mechanism 200 capable of traveling on the upper surface of the trench cover 100. The traveling mechanism 200 includes a mast 201, a fork carriage 202, and a mounting bracket 203. One end of the fork carriage 202 is located at the lower end of the mast 201, and the other end extends along the traveling direction of the traveling mechanism 200. The traveling mechanism 200 also includes an operation display screen 215 mounted on the mast 201 and a control handle 216 located at the rear end of the mast 201. The control handle 216 is equipped with a motor assembly 217 and a drive wheel 218.

[0037] In this embodiment, the walking mechanism 200 can be an electric pallet truck in the prior art. The control handle 216 controls the walking mechanism 200 to move, and the control handle 216 and the operation display screen 215 are all control technologies that are already available in existing electric pallet trucks.

[0038] In this embodiment, the walking mechanism 200 is provided with a storage mechanism 300 for storing trench cover plates 100 and a gripping mechanism 400 for gripping trench cover plates 100. The storage mechanism 300 includes a storage frame 301, and the gripping mechanism 400 includes a gripping part 401 that can reciprocate linearly along the walking direction of the walking mechanism 200. The gripping part 401 can move above the storage frame 301 and move vertically to grip the trench cover plates 100 in the storage frame 301 or store the trench cover plates 100 in the storage frame 301.

[0039] Using this linear reciprocating motion method to pick up and install the trench cover 100 from the storage frame 301 or to remove the trench cover 100 from the cable trench and store it in the storage frame 301, compared to the rotation method, the construction operation will not occupy the space outside the cable trench, and will not be restricted by the numerous supports in the site where the cable trench is located. This method is more flexible and convenient.

[0040] In this embodiment, the mounting frame 203 is horizontally arranged with one end located on the upper end of the mast 201 and the other end extending in the same direction as the fork carriage 202. The storage frame 301 is located on the fork carriage 202, and the gripping mechanism 400 is located on the mounting frame 203.

[0041] The fork carriage 202 includes two forks 204 and a fork carriage crossbeam 204 connected to the front ends of the two forks 204 at both ends. The upper surface of the fork carriage crossbeam 204 is flush with the upper surface of the forks 204. Fixed limiting plates 205 are provided on the upper surface of the two forks 204. A retractable limiting plate 206 is provided on the fork carriage crossbeam 204. The fixed limiting plate 205 and the retractable limiting plate 206 together constitute the limiting of the storage frame 301 in the traveling direction.

[0042] The fork carriage crossbeam 204 has a limiting plate mounting housing 207 on its front end face, the height of which is less than or equal to the height of the upper end face of the fork carriage crossbeam 204. The limiting plate mounting housing 207 has an accommodating cavity 208 with an upper opening for mounting a movable limiting plate 206. The accommodating cavity 208 has a limiting plate spring 209 that drives the upper end of the movable limiting plate 206 to extend above the upper end face of the fork carriage crossbeam 204. Under the action of the limiting plate spring 209, the rear end face of the movable limiting plate 206 forms a limiting surface that limits the storage frame 301. The upper end face of the movable limiting plate 206 is an inclined surface that is inclined toward the front end of the fork carriage 202. The front end face of the movable limiting plate 206 is connected to a pedal 210 that can drive the movable limiting plate 206 to descend and retract into the accommodating cavity 208.

[0043] During operation, the forks 204 drive into the bottom of the storage frame 301. In this embodiment, side limiting plates 341 are provided on both sides of the lower end face of the storage frame 301. The two side limiting plates 341 form a fork limiting part so that when the trench cover 100 is installed, the storage frame 301 can be stably located at the forks 204 of the cover installation vehicle, and the storage frame 301 can be positioned on the cover installation vehicle so that the central axis of the storage frame 301 is consistent with the central axis of the cover installation vehicle, so that the lifting claw 403 can grab, lay or store the trench cover 100, which facilitates the mechanized construction of the trench cover 100.

[0044] Then, as the storage frame 301 enters the fork 204, it applies force to the upper inclined surface of the movable limiting plate 206, causing the movable limiting plate 206 to be pressed into the receiving cavity 208. At this time, the storage frame 301 can continue to move towards the rear end of the fork 204 until the rear end of the storage frame 301 abuts against the fixed limiting plate 205 at the rear end of the fork 204. At this time, the front end of the storage frame 301 disengages from the movable limiting plate 206, and the movable limiting plate 206 extends out of the receiving groove under the action of the limiting plate spring 209. The rear end of the movable limiting plate 206 and the front end of the fixed limiting plate 205 together constitute the limiting of the storage frame 301, thereby cooperating with the upper side limiting plate 341 of the storage frame 301 to limit the storage frame 301 on the fork 204, so as to ensure the accuracy of the position of the storage frame 301 on the fork 204 and the stability of the fork 204 during movement.

[0045] When it is necessary to remove the storage frame 301 from the forks 204, simply step on the pedal 210 to cause the movable limit plate 206 to retract into the receiving cavity 208 against the elastic force of the limit plate spring 209, and the forks 204 can be removed from the bottom of the storage frame 301.

[0046] In this embodiment, the mounting frame 203 is a rectangular frame structure. The inner walls on both sides of the mounting frame 203 are provided with mounting frame sliding grooves 211, which are arranged along the extension direction of the mounting frame 203 in the length direction. The mounting frame sliding grooves 211 are U-shaped grooves that open towards the middle of the mounting frame 203. The gripping mechanism 400 includes a sliding plate 402 with both ends respectively arranged in the mounting frame sliding grooves 211 on both sides and capable of sliding along the mounting frame sliding grooves 211. In order to make the sliding plate 402 slide more smoothly, a roller 214 that cooperates with the end of the sliding plate 402 is provided on the bottom surface of the mounting frame sliding groove 211, so that the sliding plate 402 can slide through the roller 214 and reduce friction.

[0047] In this embodiment, the gripping part 401 is connected to the lower end face of the sliding plate 402 via a longitudinal telescopic mechanism. The gripping part 401 includes two claws 403 capable of moving towards or away from each other in a horizontal plane along a direction perpendicular to the sliding direction of the sliding plate 402. A drive connecting rod 212 is provided on the mounting frame 203, and a first hydraulic push rod 213 connected to the sliding plate 402 for driving the sliding of the sliding plate 402 is fixed on the drive connecting rod 212. The gripping part 401 includes a gripping frame 403, on which a second hydraulic push rod 404 connected to the claws 403 for driving the movement of the claws 403 is provided. The gripping frame 403 also has a guide rod 405 whose axial direction is parallel to the axial direction of the second hydraulic push rod 404, and the end of the guide rod 405 is connected to the claws 403.

[0048] The longitudinal telescopic mechanism includes two telescopic frames 406 respectively disposed on both sides of the sliding plate 402. Each telescopic frame 406 includes a linkage frame 407 composed of multiple intersecting and hinged connecting rods, and an upper telescopic frame slide rail 408 and a lower telescopic frame slide rail 409 respectively disposed at the upper and lower ends of the telescopic frame 406. When the connecting rods rotate around the hinge point, the linkage frame 407 can extend or shorten. The upper and lower ends of the linkage frame 407 are slidably connected to the upper telescopic frame slide rail 408 and the lower telescopic frame slide rail 409 respectively.

[0049] In addition, the connecting rod includes multiple parallel outer connecting rods 410 and multiple parallel inner connecting rods 411. The outer connecting rods 410 and inner connecting rods 411 are hinged together, and each outer connecting rod 410 and inner connecting rod 411 has hinge points at both ends and the middle. The connecting rod frame 407 is provided with inner connecting rods 411 and outer connecting rods 410, forming a double-layer telescopic connecting rod frame 407. It is hinged through multiple hinge points, which gives it better structural strength and structural stability, effectively improving the load-bearing capacity and operational stability of the telescopic frame 406.

[0050] A servo motor 412 is fixed on the sliding plate 402 for driving the telescopic frames 406 on both sides of the sliding plate 402 to extend and retract synchronously. Both sides of the sliding plate 402 are provided with pulleys 413, and each pulley 413 on both sides is provided with a wire rope 414, one end of which is connected to the motor shaft of the servo motor 412 and the other end is connected to the slide rail 409 of the lower telescopic frame.

[0051] During the installation of the trench cover 100, the sliding plate 402 is first pushed by the first hydraulic push rod 213, causing the gripping part 401 to move above the storage frame 301. Then, the servo motor 412 is started, which drives the steel wire ropes 414 on both sides to simultaneously pull or lower the telescopic frame 406, thereby achieving synchronous extension and retraction of the telescopic frames 406 on both sides. This causes the gripping part 401 to move downward to grip the trench cover 100 inside the storage frame 301. The second hydraulic push rod 404 drives the lifting claw 403 to move to the lower part of both ends of the trench cover 100. Then, the servo motor 412 is driven to run in the opposite direction, causing the gripping part 401 to move the trench cover 100 upward. Then, the first hydraulic push rod 213 pushes the sliding plate 402, causing the gripping part 401 to move upward. The hydraulic push rod 213 pushes the sliding plate 402, causing the gripping part 401 that grips the trench cover 100 to move to the installation position of the trench cover 100. Finally, the trench cover 100 is lowered, realizing the installation of the trench cover 100. The disassembly process can be carried out by reversing the operation. The entire process can be controlled by operating the display screen 215 and the control handle 216. A laser displacement sensor is set on the walking mechanism 200. The laser displacement sensor is aligned with the edge line of the cable trench top by operating the control system through the display screen. The walking mechanism 200 is controlled to move along the central axis of the cable trench. The laser displacement sensor identifies the position of the sudden change in height difference between the installed cover and the cable trench top, and the trench cover 100 is installed accurately.

[0052] In addition, this embodiment also provides the aforementioned storage mechanism for storing trench covers, namely a storage mechanism for cable trench cover construction, such as... Figures 7-11 As shown, it includes a storage frame 301, which includes a storage section 302 and an isolation section 303 disposed on one side of the storage section 302. The storage section 302 is a frame structure with a storage cavity 305 formed in the middle. The isolation section 303 is provided with a plurality of isolation racks 304 evenly arranged in the vertical direction. When isolating the storage cavity 305, the isolation racks 304 can extend horizontally into the storage cavity 305 and divide the storage cavity 305 into a plurality of cover plate placement cavities in the vertical direction. When it is not necessary to isolate the storage cavity 305, they retract into the isolation section 303.

[0053] The isolation rack 304 allows for a layer of trench cover 100 and a layer of isolation rack 304. Although the trench cover 100 is still stacked in the storage section 302 in a space-saving manner, there is a gap between the trench cover 100 for the lifting claw 403 to reach into the bottom of the trench cover 100, which facilitates the lifting claw 403 to grab the trench cover 100.

[0054] In this embodiment, the storage section 302 includes a bottom frame 306, which includes an H-shaped base plate 307. The base plate 307 includes two parallel long flat steel bars 308, and multiple short flat steel bars 309 are connected between the two long flat steel bars 308. A U-shaped limiting plate 310 is provided at the edge of each of the two long flat steel bars 308 and is perpendicular to the base plate 307. The openings of the U-shaped limiting plates 310 on both sides are opposite to each other. The base plate 307 and the U-shaped limiting plates 310 on both sides together constitute a single-plate placement cavity 311 for placing the bottommost trench cover plate 100.

[0055] The bottom frame 306 serves two purposes: firstly, it limits the movement of the bottom cover plate 100, allowing it to move only vertically and not horizontally, thus ensuring the stability of the cover plate 100 during transport by the storage frame 301; secondly, it effectively strengthens the load-bearing capacity of the bottom of the storage section 302. Although the upper cover plate 100 is isolated by the partition frame 304, its final weight still falls on the bottom frame 306. Compared to placing the cover plate 100 at the bottom solely through the partition frame 304, the bottom frame 306 provides a stronger load-bearing capacity for the entire storage section 302, ensuring stable storage of both the upper and lower cover plates 100 within the storage section 302.

[0056] In addition, the bottom plate 307 on the bottom frame 306 in this embodiment adopts an H-shape, so that the two ends of the bottom plate 307 form an inward concave structure. Thus, when the bottommost trench cover 100 is placed in the single plate placement cavity 311, the two ends of the trench cover 100 will extend out of the bottom plate 307, so that the lifting claw 403 can grasp the two ends of the bottommost trench cover 100.

[0057] In this embodiment, the isolation section 303 includes a plurality of isolation frame mounting sections 312 for mounting the isolation frame 304. The isolation frame mounting section 312 includes a guide rail 314 with a guide rail groove 313 formed inside. The isolation frame 304 is mounted on the guide rail 314. The isolation frame 304 includes two isolation rods 315 that are rotatably connected to each other. Both isolation rods 315 include a pivot end 316 that can rotate in the guide rail groove 313 and a telescopic end 317 that can extend into or out of the storage cavity 305 under the mutual rotation of the two isolation rods 315. The pivot end 316 of one isolation rod 315 is fixed relative to the length direction of the guide rail 314, while the pivot end 316 of the other isolation rod 315 can slide along the length direction of the guide rail 314. When the isolation frame 304 needs to be unfolded or retracted, the movable isolation rod 315 is controlled to slide its end in the guide rail groove 313, so that the two isolation rods 315 rotate towards each other or away from each other, thereby realizing the unfolding or retraction of the two intersecting isolation rods 315.

[0058] To ensure that the two isolation rods 315 are on the same horizontal plane, a rotating shaft 327 and a cooperating rotating groove 328 are provided at the intersection of the two isolation rods 315. Under the action of the rotating groove 328 and the rotating shaft 327, the two isolation rods 315 rotate relative to each other in the same horizontal plane, so that the two isolation rods 315 can jointly support the trench cover 100. After unfolding, they can form a wider and larger support surface on the lower surface of the trench cover 100, so as to achieve more stable support for the trench cover 100.

[0059] In this embodiment, the guide rail 314 includes an outer side plate 318 and an inner side plate 319 that are parallel to each other and vertically arranged. The outer side plate 318 and the inner side plate 319 form a guide rail groove 313. The inner side plate 319 is provided with a sliding groove for the two isolation rods 315 to pass through 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 that is connected to the end of the guide rail groove 313 and is axially arranged along the length direction of the guide rail 314. The bolt spring 322 has the tendency to drive the isolation rods 315 out of the storage cavity 305. The outer side plate 318 is provided with a bolt groove 323 for being stretched out and a bolt latch 324 provided at the end of the bolt groove 323 away from the bolt spring 322. When the bolt 321 is fastened to the bolt latch 324, the isolation rods 315 are fully extended and inserted into the storage cavity 305.

[0060] The bolt 321 includes a connecting part 325 that is connected to the pivot end 316 of the isolation rod 315. The end of the connecting part 325 away from the isolation rod 315 is rotatably connected to a limiting rod 326. The bolt latch 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 in the guide rail groove 313.

[0061] In addition, in order to make the isolation rod 315 move more smoothly in the guide rail groove 313, the guide rail 314 also includes an upper top plate 329 and a lower top plate 330. The upper and lower end surfaces of the rotating shaft end 316, which can slide along the length direction of the guide rail 314, are provided with balls 331 that can be mounted on the upper top plate 329 and the lower top plate 330 respectively.

[0062] In this embodiment, the isolation rod 315 has a diameter of 2cm and is made of polyurethane. During operation, the isolation rod 315 is controlled by pulling the bolt 321. When in use, pulling the bolt 321 causes the isolation rod 315 to overcome the elastic force of the bolt spring 322, and finally causes the bolt 321 to be pulled to the bolt lock 324 position and be limited, realizing the overall unfolding limitation of the isolation frame 304, forming a 2cm thick isolation plane space between the upper and lower adjacent trench covers 100.

[0063] When removing the trench cover 100, first unlock the bolts 321 and bolt latches 324. At this time, under the pressure and friction of the upper and lower trench covers 100, the isolation frame 304 will not retract. After 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 allows all bolts 321 and bolt latches 324 to be released at once when the trench cover 100 needs to be installed. Then, the trench cover 100 is laid one by one by the lifting claw 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 claw 403 can directly grab the lower trench cover 100. The entire process does not require the operator to repeatedly unlock and remove the isolation frame 304. Instead, the trench cover 100 can be laid continuously, effectively improving the installation efficiency of the trench cover 100.

[0064] In this embodiment, the storage section 302 also includes a column 332 vertically arranged on the bottom frame 306. The upper end of the column 332 is provided with a fixed crossbeam 333 perpendicular to each other and a movable crossbeam 334 that can be removed. The length direction of the fixed crossbeam 333 is perpendicular to the extension and retraction direction of the isolation rod 315, and the length direction of the movable crossbeam 334 is consistent with the extension and retraction direction of the isolation rod 315.

[0065] Among them, the four columns 332 are all long strips with an L-shaped cross-section, and the four columns 332 can jointly limit the horizontal movement of the inner trench cover 100 of the storage cavity 305.

[0066] The adjacent columns 332 connecting the movable crossbeam 334 are respectively provided with hinge shafts 335 and upward-opening snap-fit ​​grooves 336. One end of the movable crossbeam 334 is hinged to the hinge shaft 335 of a column 332, and the other end is snapped into the snap-fit ​​groove 336 of the adjacent column 332 from top to bottom.

[0067] The fixed crossbeam 333 and the movable crossbeam 334 can effectively improve the overall structural stability of the storage frame 301. At the same time, the four columns 332 are set in the shape of angle steel, which can effectively limit the trench cover 100 in the horizontal direction within the storage frame 301, so that the trench cover 100 will not fall off during transportation.

[0068] During storage, the movable crossbeam 334 is installed on the adjacent column 332. When operation is required, the movable crossbeam 334 is disengaged from the locking groove 336, releasing the restriction at the end of the movable crossbeam 334 of the storage frame, allowing the lifting claw 403 to enter the storage frame 301 from top to bottom and grab the trench cover 100 at the bottom of the storage frame 301.

[0069] Multiple storage frames 301 are provided, each with a wheel 337 at its bottom. Connectors 338 are provided between adjacent storage frames 301. Each connector 338 includes hooks 339 and hanging rings 340, respectively located at both ends of the storage frame 301 along the telescopic direction of the isolation rod 315. The hooks 339 and hanging rings 340 enable the connection and transport of multiple storage frames 301 as a whole. Since the trench cover 100 is relatively heavy, it is not advisable to place many trench covers 100 on a single storage frame 301. However, a large number of trench covers 100 are required during operation. Therefore, this method of connecting multiple storage frames 301 together effectively reduces the number of times the storage frames 301 need to be transported.

[0070] Side limiting plates 341 are provided on both sides of the lower end surface of the bottom frame 306 along the telescopic direction of the isolation rod 315. The two side limiting plates 341 form a fork limiting part, so that when the trench cover 100 is installed, the storage frame 301 can be stably positioned at the forks 204 of the cover installation vehicle, and the storage frame 301 can be positioned on the cover installation vehicle so that the central axis of the storage frame 301 is aligned with the central axis of the cover installation vehicle, so that the lifting claw 403 can grab and lay or store it, facilitating the mechanized construction of the trench cover 100. In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the patent of the present invention.
