Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a construction device and method for cable trenches. Background Technology

[0002] Cable trenches inside highway tunnels are the main channels for optical cables in tunnel electromechanical engineering. In order to provide conditions for the laying of optical cables, continuous cable supports need to be installed in the cable trenches, which is the immediate preceding process for laying optical cables.

[0003] The existing method involves marking the opening points in the cable trench beforehand when installing brackets in the tunnel. Workers then use an electric hammer to drill holes in the cable trench to install the brackets, and finally fix the brackets at the locations of the holes.

[0004] The limited space inside the cable trench restricts the drilling work of personnel, affecting construction efficiency, and there is room for improvement. Summary of the Invention

[0005] In order to reduce the impact of the narrow space in the cable trench on the drilling work of the workers and improve the drilling efficiency, this application provides a construction device and method for cable trenches.

[0006] This application provides a construction device and method for cable trenches, which adopts the following technical solution: A construction device for cable trenches includes a frame and a mounting frame that slides on the frame. A plurality of rollers are provided on the side wall of the frame. A rotating rod is hinged to the frame, and a connecting rod is hinged to the side wall of the rotating rod. The end of the connecting rod away from the rotating rod is hinged to the side wall of the mounting frame. A drilling mechanism for drilling is provided on the mounting frame. A plurality of rollers are installed on the side wall of the frame, and the rotating rod is inclined upwards.

[0007] By adopting the above technical solution, workers place the construction device in the prepared cable trench, with rollers supported on the outer wall of the trench. As the construction device is pushed, the rollers slide along the length of the cable trench. Workers stand in the cable trench, hold a rotating rod, and turn the rod to rotate it. The rotating rod drives the mounting frame to slide, and the mounting frame drives the drilling mechanism to move. The drilling mechanism moves towards the inner wall of the cable trench and drills a hole in the inner wall of the cable trench. Workers do not need to bend over and hold an electric hammer to drill holes, thus reducing the interference caused by the narrow cable trench to the workers and improving the construction speed.

[0008] Optionally, a sliding groove is provided on the side wall of the frame, and a plurality of rolling wheels are installed on the side wall of the mounting frame, the rolling wheels rolling in the sliding groove.

[0009] By adopting the above technical solution, when the operator turns the rotating plate, the rolling wheel rolls in the sliding groove, reducing the friction between the mounting frame and the frame body, thus making the sliding of the mounting frame smoother.

[0010] Optionally, a sliding rod is provided on the side wall of the mounting bracket, and a plurality of fixing holes are provided on the side wall of the mounting bracket. The sliding rod is fixed to the mounting bracket through the fixing holes, and the rollers are all installed on the outer wall of the sliding rod.

[0011] By adopting the above technical solution, the staff can manually adjust the position of the sliding rod according to the opening position on the inner wall of the cable trench, fix the sliding rod in a suitable position on the mounting frame, and insert bolts into the fixing holes to fix the sliding rod on the mounting frame, thereby facilitating the adjustment of the height of the electric hammer and opening holes at different positions on the inner wall of the cable trench.

[0012] Optionally, the mounting frame is provided with a support frame, a mounting plate is slidably connected to the support frame, the drilling mechanism is disposed on the mounting plate, and the mounting frame is provided with a drive component for driving the mounting plate to slide.

[0013] By adopting the above technical solution, when it is inconvenient for the staff to manually adjust the height of the sliding rod, the drive component is activated. The drive component drives the mounting plate to slide, and the mounting plate drives the drilling mechanism to move, thereby facilitating the adjustment of the height of the drilling mechanism.

[0014] Optionally, the drive assembly includes a drive gear rotatably connected to the mounting bracket, a driven gear rotatably connected to the support frame, a threaded sleeve coaxially disposed on the driven gear, and a lead screw fixed to the mounting plate. The drive gear meshes with the driven gear, the lead screw is threadedly connected to the threaded sleeve, and a drive member for driving the drive gear to rotate is provided on the side wall of the support frame.

[0015] By adopting the above technical solution, when it is necessary to adjust the height of the drilling mechanism, the drive component is activated, which drives the active tooth to rotate. The active tooth meshes with the driven tooth, and the driven tooth drives the threaded sleeve to rotate. The threaded sleeve drives the lead screw to move relative to the threaded sleeve, thereby changing the height of the mounting plate and thus changing the height of the drilling mechanism.

[0016] Optionally, a pull handle is hinged to the side wall of the driven tooth, and a snap-fit ​​groove is provided on the side wall of the mounting plate, so that the pull handle can snap into the inner wall of the snap-fit ​​groove.

[0017] By adopting the above technical solution, during the process of adjusting the height of the mounting plate, the driven tooth rotates, which drives the pull handle to rotate. At this time, the pull handle is separated from the mounting plate. When it is necessary to adjust the height of the drilling mechanism, the pull handle is moved to engage the rotating handle in the locking groove. Under the restriction of the locking groove, the mounting plate and the driven tooth are relatively fixed. At this time, the driving component drives the active tooth to rotate, which in turn drives the mounting plate to rotate, thereby changing the drilling direction of the drilling mechanism, which facilitates opening holes on both sides of the inner wall of the cable trench.

[0018] Optionally, a construction method for cable trenches includes the following steps: Construction preparation, including preparing the materials needed for the construction process; The width and depth of the cable trench are measured using a measuring tape. Fabrication of walking and support devices, including devices that travel along the length of the cable trench; The drilling mechanism is installed by mounting an electric hammer on the traveling and support device; Transportation of cable trench construction equipment: Transporting the cable trench construction equipment to the location of the cable trench; The construction equipment for the cable trench is in place and adjusted to ensure it can operate normally.

[0019] By adopting the above technical solution, before construction, workers can prepare the materials required for the construction process, assemble the bearing mechanism of the drilling mechanism, install the drilling mechanism on the bearing mechanism, place the bearing mechanism in the cable trench, and use an electric hammer to drill holes in the inner wall of the cable trench, thus eliminating the step of marking and positioning on the inner wall of the cable trench, thereby improving the efficiency of drilling holes in the inner wall of the cable trench.

[0020] Optionally, during the placement of the construction equipment in the cable trench, first adjust the electric hammer, then drill holes, measure the height and spacing of the holes, and drill continuously.

[0021] By adopting the above technical solution, the position of the electric hammer is adjusted before drilling, so that the holes drilled by the electric hammer in the cable trench are more regular.

[0022] Optionally, during continuous drilling, when the borehole is qualified, the support is fixed with anchor bolts; when a borehole fails to meet the requirements during continuous drilling, the process is restarted.

[0023] By adopting the above technical solution, the specifications of the drilled holes can be detected in a timely manner. When the drilled holes are qualified, the brackets can be fixed with anchor bolts. When unqualified holes are detected, they can be repaired in a timely manner.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The worker stands inside the cable trench and moves the drilling mechanism toward the inner wall of the cable trench by operating the rotating rod. This makes it easier to drill holes in the inner wall of the cable trench, reducing the interference caused by the small space inside the cable trench and improving the drilling efficiency.

[0025] 2. This construction method omits the marking and positioning step and proceeds directly to drilling, reducing one construction step compared to common methods. Workers can operate standing up, without being restricted by space, saving time and effort, reducing labor intensity, increasing effective working time by 30% compared to common methods, and reducing the impact of dust on personnel health. Compared to common methods, two electric hammers can operate and stop simultaneously, improving generator efficiency and achieving energy conservation and environmental protection goals.

[0026] 3. This construction method can be used not only for the installation of supports in cable trenches on highways, but also for the installation of supports in railway, municipal cable trenches, and integrated pipe trenches, as well as the installation of supports on the inside of bridge railings (this project has already extended its application to the installation of communication pipe box supports on the outside of bridge railings).

[0027] 4. Keeping operators away from the drilling mechanism's work area can effectively reduce the impact of dust during the drilling process on the operators' health. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a construction device and method for cable trenches.

[0035] Example 1 Reference Figure 1 A construction device for cable trenches includes a frame 1 and a mounting frame 2 that slides on the frame 1. Several rollers 3 are installed on the side wall of the frame 1. In this application, four rollers 3 are preferably provided. A drilling mechanism 6 for drilling is provided on the mounting frame 2. In this application, the drilling mechanism 6 is preferably an electric hammer. There are preferably two drilling mechanisms 6, which are arranged at different heights. The arrangement of two drilling mechanisms 6 allows the construction device to open two holes at a time, which doubles the drilling efficiency compared to normal construction.

[0036] Reference Figure 1 The mounting frame 2 has several fixing holes 11 on its side wall. The fixing holes 11 are arranged along the height direction of the mounting frame 2. A sliding rod 10 is fixed to the side wall of the mounting frame 2 by bolts. The opening of several fixing holes 11 makes it easy to fix the sliding rod 10 in different positions, thereby facilitating the adjustment of the relative position between the mounting frame 2 and the frame 1, and making it convenient to open holes at different heights in the inner wall of the cable trench.

[0037] Reference Figure 1 A rolling wheel 9 is fixed on the side wall of the sliding rod 10, and a sliding groove 8 is provided on the side wall of the frame 1. In this application, two sliding grooves 8 are preferably provided. The opening direction of the sliding groove 8 is perpendicular to the rolling direction of the roller 3. The rolling wheel 9 rolls in the sliding groove 8. The rolling wheel 9 is rotatably connected to the side wall of the mounting frame 2 through a rotating shaft. A rotating rod 4 is connected to the frame 1 through a rotating shaft. A connecting rod 5 is hinged to the side wall of the rotating rod 4 through a rotating shaft. The end of the connecting rod 5 away from the rotating rod 4 is hinged to the side wall of the mounting frame 2. When the operator moves the rotating rod 4, it drives the mounting frame 2 to move. The rolling wheel 9 rolls in the sliding groove 8, so that the drilling mechanism 6 moves toward the inner wall of the cable trench, which facilitates drilling holes in the inner wall of the cable trench.

[0038] According to Embodiment 1 of this application, the implementation principle of a construction device for cable trenches is as follows: the construction device is moved to the location of the cable trench, so that the roller 3 is fixed on the side wall of the cable trench. The rotating rod 4 is driven by hand to rotate. Under the drive of the connecting rod 5, the mounting frame 2 slides. The mounting frame 2 drives the drilling mechanism 6 to move, so that the drilling mechanism 6 moves towards the inner wall of the cable trench. The drilling mechanism 6 drills a hole in the inner wall of the cable trench. The worker stands in the cable trench to carry out the work, without having to bend over to drill the hole, reducing the interference caused to the worker by the narrow space of the cable trench, and improving the efficiency of drilling holes in the cable trench.

[0039] Example 2 Example 2 differs from Example 1 in that: (Refer to...) Figure 2 and Figure 3A support frame 12 is rotatably connected to the mounting frame 2 via bearings. A sliding hole is provided on the side wall of the support frame 12, and a guide rod 18 is slidably connected in the sliding hole. A mounting plate 13 is welded and fixed to the end of the guide rod 18. In this application, two mounting plates 13 are preferably provided. The mounting plates 13 are provided to fix the drilling mechanism 6. During the sliding process of the guide rod 18, the mounting plate 13 is driven to slide, thereby adjusting the height of the drilling mechanism 6 on the mounting frame 2.

[0040] Reference Figure 3 The mounting frame 2 is provided with a drive assembly 14 for driving the mounting plate 13 to slide. The drive assembly 14 includes a drive gear 141 rotatably connected to the mounting frame 2 via a rotating shaft, a driven gear 142 rotatably connected to the support frame 12 via a rotating shaft, a threaded sleeve 143 coaxially fixed to the side wall of the driven gear 142, and a lead screw 144 welded and fixed to the side wall of the mounting plate 13. The drive gear 141 meshes with the driven gear 142, and the lead screw 144 is threadedly connected to the threaded sleeve 143. During the rotation of the drive gear 141, the driven gear 142 is driven to rotate, and the driven gear 142 drives the threaded sleeve 143 to rotate, causing the lead screw 144 to slide, thereby driving the mounting plate 13 to slide.

[0041] Reference Figure 3 The mounting bracket 2 is provided with a drive component 15 for driving the active gear 141 to rotate. In this application, the drive component 15 is preferably a drive motor. The rotating shaft of the drive component 15 is coaxially fixed with the rotating shaft of the active gear 141. When the drive component 15 is started, the rotating shaft of the drive component 15 rotates, thereby driving the active gear 141 to rotate.

[0042] Reference Figure 3 A pull handle 16 is hinged to the side wall of the driven tooth 142, and a guide groove 19 is provided on the side wall of the support frame 12. In this application, the guide groove 19 is preferably annular, and a snap-fit ​​groove 17 is provided on the side wall of the support frame 12. The guide groove 19 and the snap-fit ​​groove 17 are connected. When the height of the mounting plate 13 is adjusted, the end of the pull handle 16 is located in the guide groove 19. During the rotation of the driven tooth 142, the end of the pull handle 16 slides in the guide groove 19. When it is necessary to adjust the drilling direction of the drilling mechanism 6, the pull handle 16 is pulled and snapped into the snap-fit ​​groove 17. Under the connection of the pull handle 16, the driven tooth 142 and the support frame 12 are relatively stationary. At this time, during the rotation of the driving tooth 141, the support frame 12 and the mounting plate 13 are driven to rotate synchronously, so that the orientation of the drilling mechanism 6 changes, which is convenient for different openings in the cable trench.

[0043] Example 2: The implementation principle of a construction device for cable trenches is as follows: When it is necessary to adjust the height of the drilling mechanism 6, the drive component 15 is activated. The shaft of the drive component 15 rotates, causing the active gear 141 to rotate. The active gear 141 meshes with the driven gear 142, and the driven gear 142 causes the threaded sleeve 143 to rotate. The lead screw 144 slides, thereby causing the mounting plate 13 to slide. When it is necessary to adjust the drilling direction of the drilling mechanism 6, the pull handle 16 is pulled and engaged in the engagement groove 17. At this time, the drive component 15 is activated. The shaft of the drive component 15 rotates, causing the active gear 141 and the driven gear 142 to rotate. During this process, the bearing frame 12 rotates synchronously, thereby adjusting the drilling direction of the drilling mechanism 6, which facilitates opening holes on both sides of the cable trench.

[0044] Example 3: A method for constructing a cable trench, comprising the following steps: Reference Figure 4 Construction preparation involves preparing materials for manufacturing the construction equipment, then measuring the width and depth of the cable trench using measuring equipment such as a tape measure. Based on the dimensions of the cable trench, corresponding walking devices and linkage mechanisms are manufactured. The walking device must ensure that the entire equipment can move freely along the cable trench, the support device must allow operators to stand and operate both outside and inside the cable, and the normal operating range of the handle must ensure the drilling depth.

[0045] Install the drilling mechanism 6 and install it on the walking device with bolts to form the construction device in Embodiment 1; transport the equipment to the location of the cable trench so that the roller 3 rolls on the outer top wall of the cable trench, thereby facilitating the drilling of holes on the inner wall of the cable trench.

[0046] Once the equipment is in place, adjust the drilling mechanism 6. After adjusting the drilling equipment, drill holes in the inner wall of the cable trench. Measure the height and spacing of the holes using measuring tools such as a tape measure. Then drill continuously. Once the holes meet the requirements, fix the bracket with anchor bolts.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
