Description

Technical Field

[0001] The present invention relates to the technical field of tunneling ditch cable trough trolleys and their usage methods. Specifically, it relates to tunneling ditch cable trough trolleys and their usage methods. Background Art

[0002] A tunneling ditch cable trough trolley is a special device used for installing and maintaining cables in tunnel projects. Generally, the cable trough trolley is mainly used for the erection and maintenance of cable troughs, and plays an important role in the processes of cable laying, equipment installation, and repair in tunnels. Its basic function is to support the cable trough through the vehicle body structure and can be moved according to actual needs, so as to achieve the precise layout and adjustment of the cable trough in the tunnel.

[0003] In the prior art, a Chinese utility model with a publication number of "CN221879417U", a tunnel combined ditch cable trough formwork trolley device, is composed of: a wheeled walking trolley, a frame-shaped body, a lifting beam, trolley walking wheels, a lifting arm, a winch, a steel wire rope, a combined ditch cable trough formwork, a first formwork section, a second formwork section, a third formwork section, a straight wall formwork, a ground fixing beam, an anti-floating positioning screw, a lifting lug, a pin hole, a formwork section connecting plate, a straight wall formwork connecting plate, and a straight wall formwork connecting ear; a pair of lifting beams are arranged at the upper parts of both ends of the wheeled walking trolley, a pair of lifting arms are arranged at the same end of a pair of lifting beams, a balance beam is arranged at the other end of a pair of lifting beams, a pair of winches are arranged at the lower ends of a pair of lifting arms, and a sliding mechanism is arranged between a pair of winches and the lifting arms; a combined ditch cable trough formwork is correspondingly arranged below a pair of lifting arms, the combined ditch cable trough formwork is a segmented combination with at least three formwork sections, and at least three formwork sections are respectively set as a first formwork section, a second formwork section, and a third formwork section. The combined ditch cable trough formwork is segmented and combined into three formwork sections or five formwork sections according to the length of a single construction section.

[0004] This technology aims to solve the problems of different construction section lengths and spans by adopting a multi-section formwork system. During the construction process, workers can select formwork sections of different lengths according to the specific construction trough length, so as to achieve flexible adjustment and adapt to construction requirements of different lengths. This method effectively reduces the labor intensity of workers, improves construction efficiency, and speeds up the project progress. However, the existing technology still faces a series of problems: First, the existing technology uses a walking wheel system to move the trolley. Although the use of walking wheels reduces the cost of laying tracks and improves the mobility of the trolley, the walking wheel system has obvious deficiencies in precision control. The precision of the trolley is relatively low, resulting in its inability to ensure high-precision alignment when moving to the designated position. This directly affects the installation precision of the formwork. Especially during the lowering process of the cable trench formwork, inaccurate precision easily leads to deviations between the cast cable trench and the design drawings. In this way, either additional manual adjustment and precise positioning by workers are required, increasing the labor intensity; or there are large errors during the construction process, affecting the project quality and progress; in addition, due to the insufficient precision of the trolley, workers may need to make frequent adjustments and corrections during the parking process of the trolley to ensure the accurate positioning of the formwork. This not only consumes more time and energy, but also increases the operation difficulty of workers and reduces the construction efficiency. Summary of the Invention

[0005] The present invention provides a tunneling and installing gutter and cable trench trolley, which reduces the operation difficulty of workers, improves the precision of cable trench construction, and also enhances the overall construction effect.

[0006] The technical solution of the present invention is as follows: A tunneling and installing gutter and cable trench trolley, comprising a trolley body and a moving module for driving the movement of the trolley body; A first cross beam plate and a second cross beam plate are fixedly connected to the trolley body, and the first cross beam plate and the second cross beam plate are symmetrically arranged; A plurality of stretching plates are slidably connected between the first cross beam plate and the second cross beam plate. Lifting frames are connected to the stretching plates on the same side, and a plurality of placing modules for lowering the casting formwork are fixedly connected to each of the lifting frames; A stretching assembly for driving the stretching plates on both sides to translate and stretch along the two sides of the trolley body is connected between two adjacent stretching plates. A first hydraulic rod is hinged between each stretching plate and the adjacent first cross beam plate or second cross beam plate; A plurality of first support plates are fixedly connected to one side of each stretching plate facing the lifting frame. Two support columns are fixedly connected between two adjacent first support plates. An adjusting block is slidably connected to the support column, and the lifting frame is hinged to the two adjusting blocks on the same side; Two clamping cylinders are slidably connected to the second cross beam plate, and the telescopic shafts of each clamping cylinder are fixedly connected to the adjacent adjusting block.

[0007] Furthermore, the stretching component includes two second support plates, each of the second support plates is fixedly connected to the trolley body, a protective housing is fixedly connected to each of the second support plates, clamping blocks are fixedly connected to both outer sides of the protective housing, a linkage plate is hinged to each of the clamping blocks, and a receiving block is hinged to one end of each linkage plate away from the clamping block; Driving plates are hinged to both sides of the receiving block, and a driving component for driving the driving plates on both sides is connected between the two driving plates; A second hydraulic rod is hinged between each clamping block and the adjacent linkage plate; A limiting block is fixedly connected to one side of each clamping block facing the adjacent stretching plate, two limiting columns are slidably connected to each of the limiting blocks, and limiting plates are fixedly connected to both ends of the limiting columns.

[0008] Furthermore, the driving component includes a number of first driving shafts, each of the first driving shafts is rotatably connected to the protective housing, both ends of each first driving shaft are fixedly connected to the driving plate respectively, a first gear is fixedly connected to each of the first driving shafts, a second gear is meshed with the upper side of each of the first gears, a bearing seat is rotatably connected to one side of each of the second gears, a servo motor is rotatably connected to the side of the bearing seat away from the second gear, and the driving shaft of the servo motor is fixedly connected to the second gear; Each servo motor is fixedly connected to the inner wall of the protective housing.

[0009] Furthermore, the driving component includes a second driving shaft and a third driving shaft, the second driving shaft and the third driving shaft are both rotatably connected to the protective housing, and both ends of the second driving shaft and the third driving shaft are fixedly connected to the respective driving plates; A first gear is fixedly connected to the second driving shaft, a second gear is meshed with the upper side of the first gear, a bearing seat is rotatably connected to one side of the second gear, a servo motor is rotatably connected to the side of the bearing seat away from the second gear, and the driving shaft of the servo motor is fixedly connected to the second gear; The servo motor is fixedly connected to the inner wall of the protective housing; A first synchronous pulley is fixedly connected to both the second driving shaft and the third telescopic shaft, a second synchronous pulley is connected between the two first synchronous pulleys, and the second synchronous pulley is rotatably connected to the inner wall of the protective housing; A synchronous belt is meshed with the second synchronous pulley and the two first synchronous pulleys.

[0010] Furthermore, the distance between the stretching plate and the lifting frame body is greater than the axial length of the support column.

[0011] The beneficial effects of the present invention are: By adding a stretching component, the accuracy error of the trolley body when it moves to the specified position can be effectively compensated, avoiding the workers from frequently adjusting the parking position of the trolley body. This improvement enables the stretching component to more easily adjust the placement module of the lowered casting template, ensuring that all operations during the construction process can meet the construction standards, greatly reducing the difficulty of workers' operations. In the end, the optimization of the design not only improved the accuracy of the cable trough construction, but also significantly improved the overall construction effect. In addition, with the output of the positioning electric cylinder, the distance accuracy adjustment perpendicular to the stretching plate can be achieved. The coordinated work of the positioning electric cylinder and the stretching component further enhances the coordination accuracy between the placement module and the construction area. The realization of this precise adjustment ensures the accuracy and consistency of each construction link, making the entire construction process more efficient and precise.

[0012] Another object of the present invention is to provide a method for using a tunnel-mounted trench cable trough trolley, which reduces the labor intensity of workers and improves the overall construction efficiency and work quality.

[0013] The following steps are involved: S100: Alignment: The worker drives the position of the trolley body through the moving module, so that the placement module equipped with the casting template moves to the marking area in the tunnel, waiting for the calibration between the stretching plate and the side marking area; S200: Calibration 1: by starting the stretching components on one side or both sides, the two stretching plates on the same side or both sides are moved toward the marking area at the same time, and by adjusting the moving distance of the two stretching plates on the same side, the parallelism between the side of the lifting frame and the marking area is controlled; S300: Calibration 2: Use the positioning electric cylinder to accurately control the position of the lifting frame on the two stretching plates on the same side, and cooperate with the stretching component to make the lifting frame and the marked area more accurately aligned; S400: Start the placement module: Start the hydraulic rods on the placement module to make the casting template and the partition fall into the marked area, and then fix the lowering position, and cast the cavity composed of the casting template and the partition. After ensuring that there is no gap in the casting, the casting template and the partition are reset and removed through the placement module; S500: Reset: After the cable trough of the designated area is processed, the stretching plates on both sides are reset through the stretching assembly, and the placement module is reset. The extension and retraction of the telescopic axis of the positioning electric cylinder is adjusted accordingly as the next area is processed; S600: Secondary construction: Workers use the mobile module to move the trolley body for a second time to move it to the next construction area.

[0014] Another beneficial effect of the present invention is: Improved the accuracy and efficiency of the construction process. Through step-by-step operations, this method first ensures the precise alignment of the trolley body position, and then, through the coordinated action of the stretching component and the clamping cylinder, precisely adjusts the alignment of the lifting frame and the scribed area, improving the construction accuracy. By precisely controlling the movement of the stretching plate and the positioning of the lifting frame, it avoids the cumbersome manual adjustment and errors, reducing the operation difficulty. At the same time, the reset step simplifies the repositioning of the equipment, providing higher efficiency and accuracy for subsequent construction. This method not only improves the accuracy of cable trench construction but also reduces the labor intensity of workers, enhancing the overall construction efficiency and operation quality.

SPECIFIC EMBODIMENTS

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0019] like Figures 1 to 7 As shown, this embodiment proposes a tunnel-mounted water trench cable trough trolley, comprising a trolley body 11 and a moving module 12 for moving and driving the trolley body 11; The first cross beam plate 13 and the second cross beam plate 14 are fixedly connected to the trolley body 11, and the first cross beam plate 13 and the second cross beam plate 14 are symmetrically arranged; A plurality of stretching plates 15 are slidably connected between the first cross beam plate 13 and the second cross beam plate 14, each lifting frame 16 is connected to two stretching plates 15 on the same side, and a plurality of placement modules for lowering the casting template are fixedly connected to the lifting frame 16; A stretching assembly for driving the stretching plates 15 on both sides to perform translational stretching along the two sides of the trolley body 11 is connected between two adjacent stretching plates 15, and a first hydraulic rod 17 is hinged between each stretching plate 15 and the adjacent first cross beam plate 13 or second cross beam plate 14; A plurality of first support plates 18 are fixedly connected to the side of each stretching plate 15 facing the lifting frame 16, two support columns 19 are fixedly connected between two adjacent first support plates 18, an adjustment block 110 is slidably connected to the support column 19, and the lifting frame 16 is hinged to the two adjustment blocks 110 on the same side; The two positioning electric cylinders 111 are both slidably connected to the second crossbeam plate 14, and the telescopic shaft of each positioning electric cylinder 111 is fixedly connected to the adjacent adjustment block 110; By adding a stretching component, the accuracy error of the trolley body 11 when it moves to the specified position can be effectively compensated, avoiding the workers from frequently adjusting the parking position of the trolley body 11. This improvement enables the stretching component to more easily adjust the placement module of the lowered casting template, ensuring that all operations during the construction process can meet the construction standards, greatly reducing the difficulty of workers' operations. In the end, the optimization of the design not only improves the accuracy of the cable trough construction, but also significantly improves the overall construction effect; In addition, with the output of the positioning electric cylinder 111, the distance perpendicular to the stretching plate 15 can be precisely adjusted. The coordination between the positioning electric cylinder 111 and the stretching assembly further enhances the matching accuracy between the placement module and the construction area. The realization of this precise adjustment ensures the accuracy and consistency of each construction link, making the entire construction process more efficient and accurate.

[0020] likeFigures 4 to 7 As shown in the figure, the stretching component includes two second support plates 21, each of which is fixedly connected to the trolley body 11. Each second support plate 21 is fixedly connected to each protective housing 22. Two clamping blocks 23 are respectively fixedly connected to the outer sides of both sides of the protective housing 22. Each clamping block 23 is hinged to each linkage plate 24. One end of each linkage plate 24 away from the clamping block 23 is hinged to each receiving block 25; Two driving plates 26 are respectively hinged to both sides of the receiving block 25, and a driving component for driving the two driving plates 26 on both sides is connected between the two driving plates 26; Each second hydraulic rod 27 is hinged between each clamping block 23 and the adjacent linkage plate 24; One side of each clamping block 23 facing the adjacent stretching plate 15 is fixedly connected to each limiting block 28. Two limiting columns 29 are slidably connected to the limiting block 28. Two limiting plates 210 are respectively fixedly connected to both ends of the limiting column 29; The driving plate 26 drives the receiving block 25 to move, and the linkage plate 24 under the receiving block 25 is used to limit it, so as to ensure that the upper side of the receiving block 25 is always parallel to the second support plate 21 during the flipping process. During the flipping process, the receiving block 25 drives one side of the stretching plate 15 to move outward through the connection with the limiting block 28. This can effectively compensate for the precision error when the trolley body 11 moves to the designated position, and avoids the workers from frequently adjusting the docking position of the trolley body 11. In this way, the stretching component can more easily and accurately adjust the placement module for lowering the casting template, so as to ensure that all operations during the construction process meet the construction standards and reduce the operation difficulty of the workers. Finally, this design not only improves the precision of the cable trench construction, but also significantly improves the construction effect.

[0021] As Figures 4 to 6 shown in the figure, the driving component includes several first driving shafts 31. Each first driving shaft 31 is rotatably connected to the protective housing 22. Both ends of each first driving shaft 31 are respectively fixedly connected to the driving plate 26. Each first gear 32 is fixedly connected to each first driving shaft 31. Each second gear 33 is engaged with the upper side of each first gear 32. One side of each second gear 33 is rotatably connected to each bearing seat 34. The side of the bearing seat 34 away from the second gear 33 is rotatably connected to the servo motor 35. The driving shaft of the servo motor 35 is fixedly connected to the second gear 33; Each servo motor 35 is fixedly connected to the inner wall of the protective housing 22; By driving the first drive shaft 31 on one side through an independent servo motor 35, separate control of the stretching plates 15 on the same side or both sides can be achieved. Such a design improves the distance accuracy of the movement of the stretching plates 15, enabling precise control of the scribing areas to be processed on both sides of the trolley body 11. By precisely adjusting the position of the stretching plates 15, high-precision scribing during the construction process of the trolley body 11 can be ensured, thereby improving the overall construction accuracy and operation efficiency.

[0022] As Figures 1 to 3 shown, the distance between the stretching plate 15 and the lifting frame 16 is greater than the axial length of the support column 19; When the lifting frame 16 undergoes angular flipping through the stretching plates 15 on the same side, in order to ensure that no interference occurs during the flipping process, the relative movement between the lifting frame 16 and the stretching plates 15 needs to be reasonably designed. Specifically, during the small-angle flipping process, it should be avoided that the movement of the lifting frame 16 causes collision or interference with the stretching plates 15, so as to ensure that the lifting frame 16 can smoothly and stably perform angular flipping and maintain a normal working state, avoiding jamming or damage caused by interference. Embodiment 2

[0023] In this example, the driving method of the driving component is improved on the basis of Embodiment 1; As Figures 4 to 7 shown, the driving component includes a second drive shaft 41 and a third drive shaft 42. Both the second drive shaft 41 and the third drive shaft 42 are rotatably connected to the protective housing 22, and both ends of the second drive shaft 41 and the third drive shaft 42 are fixedly connected to the respective drive plates 26; The first gear 32 is fixedly connected to the second drive shaft 41. The second gear 33 is meshed on the upper side of the first gear 32. One side of the second gear 33 is rotatably connected to the bearing seat 34. The side of the bearing seat 34 away from the second gear 33 is rotatably connected to the servo motor 35. The drive shaft of the servo motor 35 is fixedly connected to the second gear 33; The servo motor 35 is fixedly connected to the inner wall of the protective housing 22; Two first synchronous wheels 43 are respectively fixedly connected to the second drive shaft 41 and the third drive shaft 42. The second synchronous wheel 44 is connected between the two first synchronous wheels 43. The second synchronous wheel 44 is rotatably connected to the inner wall of the protective housing 22; The synchronous belt 45 is meshed on the second synchronous wheel 44 and the two first synchronous wheels 43; By installing a second synchronous pulley 44 and two first synchronous pulleys 43 and engaging them with a synchronous belt 45 for transmission, it is possible to ensure that the stretching plates 15 on both sides move synchronously. This design not only effectively reduces the need for multiple driving devices but also improves the linkage cooperation between the stretching plates 15 on both sides. By simplifying the drive system, the complexity of the overall equipment is reduced, thereby reducing the procurement cost while also decreasing the subsequent usage and maintenance costs. Embodiment 3

[0024] As Figures 1 to 7 shown, based on Embodiment 1, this embodiment proposes a method for using a tunneling and installing gutter cable trough trolley, including the following steps: S100: Alignment: Workers drive the position of the trolley body 11 through the moving module 12, causing the placement module equipped with the casting template to move to the marked area in the tunnel and waiting for calibration between the stretching plate 15 and the side marked area; S200: Calibration 1: By starting the stretching components on one side or both sides, the two stretching plates 15 on the same side or both sides are simultaneously moved towards the marked area. By adjusting the moving distances of the two stretching plates 15 on the same side, the parallelism between the side of the lifting frame 16 and the marked area is controlled; S300: Calibration 2: Through the clamping cylinder 111, precisely control the position of the lifting frame 16 on the two stretching plates 15 on the same side, and cooperate with the stretching components to enable the lifting frame 16 to be more precisely aligned with the marked area; S400: Start of the placement module: Start the hydraulic rods on the placement module, causing the casting template and the partition to both fall within the marked area. Then, after fixing the lowering position, pour the cavity composed of the casting template and the partition, and ensure that there are no gaps during pouring. After that, move the casting template and the partition out through the placement module's reset movement; S500: Reset: After the cable trough in the designated area is processed, reset the stretching plates 15 on both sides through the stretching components, and also reset the placement module. The expansion and contraction of the telescopic shaft of the clamping cylinder 111 are adjusted correspondingly with the processing of the next area; S500: Secondary construction: Workers move the trolley body 11 a second time through the moving module 12, causing it to move to the next construction area.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
