Description

Technical Field

[0001] The invention relates to the technical field of tunnel cable construction, and in particular to a tunnel cable bracket installation device. Background Art

[0002] During the tunnel construction process, the installation of cable racks is an essential operation item. At present, the way to install cable racks is to fix the cable racks on the wall with mounting parts. In order to achieve the purpose of firmly fixing the cable rack, it is necessary to fix the cable rack at one mounting position through four connectors to ensure the reliability of the connection. Before installing the cable rack in the tunnel, it is first necessary to drill holes in the wall, and four holes need to be drilled with an electric drill at each mounting position. Since the cable racks will extend and arrange along the side wall of the tunnel, and the cable racks supporting the same cable have the same height. This requires workers to hold electric drills and drill four mounting holes for each mounting position on the side wall of the tunnel in turn. This operation method is not only extremely inefficient, but also the four mounting holes in the same mounting position are very easy to be difficult to control the drilling accuracy during the drilling operation, which increases the difficulty of subsequent installation of the connectors. Therefore, it is necessary to improve the drilling operation method during the installation of the cable rack.

[0003] For example, the Chinese patent application number 201920780274.5 discloses a wall punching device for interior decoration, including a base plate, on the lower surface of which a moving mechanism is fixedly mounted. In actual use, the device is pushed to a specified position, and under the action of a first electric telescopic rod, the motor is raised to a specified height, and the side of the second protective cover away from the cylinder is brought into contact with the wall, the device is fixed with a foot brake, and then under the action of a second electric telescopic rod, the motor is slowly brought close to the wall, and the drill bit passes through the first protective cover, the cylinder, and the second protective cover in sequence to start the punching operation.

[0004] For another example, the Chinese patent with application number 202020745390.6 discloses a wall drilling device for house construction, including a mounting frame, a controller and a drill rod, the mounting frame is provided with a limit part and an adjustment part, the adjustment part is provided with a driving device that drives the drill rod to rotate through a connecting part; the fixing part includes: at least two suction cups, the suction cups are located on the side end surface of the mounting frame, and the suction cups are provided with regulating valves. In actual use, the telescopic part adopts a hydraulic push rod with a self-locking function, the top of the mounting frame is provided with a slide groove, the bottom of the movable plate is provided with a slider embedded in the slide groove, the movable plate is movable, and the telescopic part is retractable, thereby increasing the range of motion of the drill rod.

[0005] The above patents all set a support structure at the bottom of the drill bit and the motor to drive the drill bit and the drilling machine to perform lateral displacement and height adjustment, thereby increasing the range of motion of the drill bit and the rapid adjustment of the drilling position. Although it can achieve switching between different installation positions, when applied to the installation of tunnel cable brackets, in the drilling operation of four installation holes in the same installation position, the position adjustment of the drill bit cannot directly adapt to the hole positions of the four installation holes for switching and positioning, which will make the process of switching the hole positions for drilling extremely inconvenient, and cannot effectively adapt to the sequential drilling operation of four installation holes in the same installation position in the installation of tunnel cable brackets.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0042] like Figures 1 to 4 , Figure 6 and Figure 8 As shown, a typical embodiment of the present invention provides a tunnel cable installation device, which is used for drilling installation holes during tunnel cable installation, comprising:

[0043] A base 1 is provided with a lifting seat 2 capable of displacement in the left-right direction, a slide seat 3 capable of displacement in the front-back direction is provided on the top of the lifting seat 2, and a motor 4 is installed on the top of the slide seat 3;

[0044] A fixed plate 5 is fixedly mounted on the base 1 and is located in front of the motor 4. A chuck 6 is rotatably arranged at the center of the fixed plate 5. Four claws 7 for locking the chuck 6 are arranged inside the fixed plate 5 and are symmetrically distributed at the center.

[0045] The support arm 8 has an inner end fixedly connected to the front side of the chuck 6, and a drill assembly 9 is rotatably sleeved on the outer end thereof. A drill rod 9.1 is installed at the front end of the drill assembly 9, and the rear end of the drill assembly 9 is detachably connected to the motor 4. During one rotation of the chuck 6, the four positions where the drill assembly 9 is locked by the claw 7 correspond to the positions of the four mounting holes that need to be drilled when installing the tunnel cable bracket;

[0046] A rotating arm 10, the inner end of which is rotatably mounted at the center of the front side of the chuck 6, and a push rod 11 is connected to the inner end of the rotating arm 10, and the push rod 11 is arranged to make the four claws 7 disengage from the chuck 6 when passing through the inner end of any claw 7;

[0047] The blocking rod 12 is arranged in an arc structure with the center of the fixed disk 5 as the center. One end of the blocking rod 12 is fixed on the support arm 8. When the push rod 11 causes the claw 7 to disengage from the chuck 6, the rotating arm 10 contacts the other end of the blocking rod 12.

[0048] The limiting plate 13 is provided with a strip groove 14 inside, one end of the strip groove 14 is rotatably sleeved outside the drill bit assembly 9, and a limiting cylinder 15 is vertically installed on the outer end of the rotating arm 10. The limiting cylinder 15 is movably inserted into the strip groove 14, and the distance between the center of the limiting cylinder 15 and the center of the drill rod 9.1 is adapted to the distance between two adjacent mounting holes of the four mounting holes of the tunnel cable bracket.

[0049] During the installation of the tunnel cable bracket, four square mounting holes need to be drilled on the tunnel wall corresponding to the upper and lower ends of the cable bracket. The motor 4 is driven to move by the left and right displacement of the lifting seat 2 on the base 1 and the lifting movement of the lifting seat 2 to adapt to the sequential drilling operation of the four mounting holes.

[0050] The fixing plate 5 is used to install the chuck 6, and the drill assembly 9 is supported by the chuck 6 through the support arm 8. The claw 7 can lock the support arm 8 by locking the chuck 6, and then lock the drill assembly 9 in the drilling position. Specifically in this embodiment, the length of the support arm 8 is determined according to the distance between two adjacent mounting holes in the four mounting holes, so that the distance between the axis of the drilling assembly and the center of the chuck 6 is adapted to half the diagonal length of the square surrounded by the four mounting holes. At this time, when the claw 7 locks the chuck 6, the axis of the drill assembly 9 is just aligned with the center of the mounting hole to be drilled in the tunnel wall.

[0051] On the one hand, the rotating arm 10 is used to drive the push rod 11 to rotate, and the push rod 11 is used to push the claw 7 outward, so that the claw 7 is separated from the chuck 6, thereby unlocking the chuck 6. On the other hand, it is used to push the blocking rod 12, and the blocking rod 12 is used to push the support arm 8 to rotate, so that the drill bit assembly 9 switches to the next position to be drilled.

[0052] One end of the limit plate 13 is rotatably mounted on the outer end of the support arm 8 so that the outer end of the support arm 8 will not be displaced in the strip groove 14. The other end of the limit plate 13 cooperates with the limit cylinder 15 to ensure that the distance between the limit cylinder 15 and the outer end of the support arm 8 is adapted to the distance between two adjacent mounting holes, so as to better position the drill assembly 9 during adjustment.

[0053] During the rotation of the rotating arm 10, the limiting cylinder 15 will move toward one side of the drill assembly 9 in the strip groove 14, and at this time, the limiting plate 13 will deflect. During the movement of the rotating arm 10 from the state of being separated from the blocking rod 12 to the state of being in contact with the blocking rod 12, the push rod 11 pushes the claw 7 to separate from the chuck 6, and then, during the subsequent rotation of the rotating arm 10, the rotating arm 10 pushes the support arm 8 to swing through the blocking rod 12, and the support arm 8 drives the drill assembly 9 to move. During this process, if the drill assembly 9 falls downward under its own gravity, the limiting effect of the limiting cylinder 15 on the limiting plate 13 can prevent the drill from falling freely, thereby achieving effective control of the drill assembly 9, which is more conducive to adjusting the position of the drill assembly 9.

[0054] like Figures 1 to 4 As shown, four slots 16 are provided on the circumferential surface of the chuck 6, the claw 7 includes a claw body 7.1, a guide rod 7.2, a locking spring 7.3 and an arc plate 7.4, the guide rod 7.2 is penetrated on the circumferential surface of the fixed disk 5, the inner end of the guide rod 7.2 is fixedly connected to the outer side surface of the claw body 7.1, the locking spring 7.3 is connected between the claw body 7.1 and the fixed disk 5, and arc plates 7.4 are provided on both sides of the claw body 7.1, and the two arc plates 7.4 are staggered in the radial direction, and the opposite ends of the two arc plates 7.4 located between the two claw bodies 7.1 are in an overlapping state.

[0055] By setting the arc plate 7.4, when any one of the claws 7 is pushed out of the slot 16 by the push rod 11, all the claws 7 will be withdrawn from the corresponding slot 16, thereby achieving the effect of all the claws 7 being synchronously disengaged from the slot 16 and unlocking the chuck 6.

[0056] When the claw 7 is pulled out of the slot 16, the locking spring 7.3 is compressed. After the claw 7 is separated from the slot 16, when the arm 10 pushes the support arm 8 through the stop rod 12, the chuck 6 rotates with the support arm 8, and the slot 16 and the claw 7 are in a misaligned state. At this time, the inner end of the claw body 7.1 is displaced on the circumferential surface of the chuck 6, so that the locking spring 7.3 remains in a compressed state. When the chuck 6 rotates 90°, the drill assembly 9 moves to the next position to be drilled. At this time, the claw body 7.1 is automatically inserted into the slot 16 on its inner side under the action of the locking spring 7.3, and the chuck 6 is repositioned, thereby realizing the positioning of the drill assembly 9. Therefore, the chuck 6 can be automatically unlocked by directly rotating the arm 10, and each time the drill assembly 9 moves to the next drilling position, the claw 7 automatically locks the chuck 6, making the position adjustment of the drill bit extremely convenient, greatly improving the construction efficiency.

[0057] like Figure 2 and Figure 4As shown, the slot 16 is a rectangular slot, the width of the claw body 7.1 is adapted to the slot 16, and a notch 7.5 is provided on the inner end of the claw body 7.1 away from the side squeezed by the push rod 11, and the notch 7.5 is radially located within the slot cavity range of the slot 16.

[0058] By providing the notch 7.5, the width of the inner end of the claw body 7.1 is smaller than the width of the slot 16. Therefore, when the chuck 6 rotates 90°, when one side of the slot 16 moves to the range of the notch 7.5, the inner end of the claw body 7.1 can be inserted into the slot 16. During the subsequent rotation of the chuck 6, the claw body 7.1 is continuously inserted into the slot 16, thereby ensuring that the claw 7 can be more stably inserted into the slot 16, thereby locking the chuck 6.

[0059] like Figure 2 and Figure 4 As shown, when the push rod 11 squeezes the inner end of the claw 7, the contact parts of the push rod 11 and the inner end of the claw 7 are both sloped surfaces, the end surface of the outer end of the push rod 11 and the end surface of the inner end of the claw 7 are both flat surfaces, and the front side surface of the claw 7 is located on the front side of the chuck 6.

[0060] like Figures 5 to 10 As shown, the drill assembly 9 also includes a drill barrel 9.2, a polygonal connecting rod 9.3, a first annular groove 9.4, a first sleeve ring 9.5 and a reset spring 9.6. The drill rod 9.1 is installed at the front end of the drill barrel 9.2, the limit plate 13 is rotatably sleeved on the front end of the drill barrel 9.2, the polygonal connecting rod 9.3 is fixed to the tail end of the drill barrel 9.2, the first annular groove 9.4 is set on the surface of the drill barrel 9.2, the first sleeve ring 9.5 is movably sleeved on the first annular groove 9.4, and the first sleeve ring 9.5 is fixedly connected to the outer end of the support arm 8, the two ends of the reset spring 9.6 are respectively connected to the first sleeve ring 9.5 and the rear inner wall surface of the first annular groove 9.4, the power shaft of the motor 4 is connected with a plug-in sleeve 17, and the front end surface of the plug-in sleeve 17 is provided with a polygonal connecting groove 18 for inserting the polygonal connecting rod 9.3.

[0061] By pushing the slide 3 forward, the motor 4 drives the plug sleeve 17 to move forward. The polygonal connecting groove 18 on the plug sleeve 17 is covered with the polygonal connecting rod 9.3, so that after the motor 4 is started, the drill assembly 9 can be mobilized to rotate to achieve the drilling operation.

[0062] When adjusting the position of the drill assembly 9, the slide 3 is directly pulled backwards to pull the polygonal connecting rod 9.3 out of the polygonal connecting groove 18. At this time, the drill assembly 9 is separated from the motor 4, and the position of the drill assembly 9 can be adjusted. After the position of the drill assembly 9 is adjusted, the motor 4 can be adjusted to a position where it can be connected to the drill assembly 9 again by lifting and lowering the lifting seat 2 and sliding the lifting seat 2 in the left and right directions on the base 1.

[0063] The first collar 9.5 supports the entire drill assembly 9. During the drilling process, the motor 4 is displaced forward by pushing the slide 3 forward. At this time, the plug sleeve 17 pushes the drill assembly 9 forward, so that the drill drills a hole in the tunnel wall, and the reset spring 9.6 is compressed. In the subsequent process of pulling the drill rod 9.1 out of the installation hole, the motor 4 moves backward, and the reset spring 9.6 causes the drill tube 9.2 and the drill to move backward as a whole, thereby preventing the motor 4 from moving backward and causing the plug sleeve 17 to separate from the drill assembly 9, and enabling the drill rod 9.1 to be automatically pulled out of the installation hole.

[0064] like Figure 4 , Figure 6 and Fig.10 As shown, a mounting block 19 is provided on the front side of the chuck 6, the support arm 8 is slidably inserted into the mounting block 19, and a fastening bolt 20 for fixing the support arm 8 is provided on the mounting block 19, the rotating arm 10 is an elastic telescopic rod, the limiting cylinder 15 is fixedly connected to the movable end of the rotating arm 10, and the outer side surface of the blocking rod 12 is provided with a supporting plate 21 supported on the inner side surface of the limiting plate 13, and the rotating arm 10 is in a stretched state.

[0065] The distance between the drill assembly 9 and the center of the fixed disk 5 can be adjusted by sliding the support arm 8 on the mounting block 19 to adapt to the drilling operation of the mounting holes with different spacings. By setting the rotating arm 10 in a stretched state, the rotating arm 10 always exerts an inward pulling force on the limit plate 13. At the same time, the support plate 21 is used to support the limit plate 13 toward the fixed disk 5, so that the end of the limit plate 13 away from the drill assembly 9 is simultaneously subjected to forces in both the inner and outer directions, so that the limit plate 13 is always parallel to one side of the square surrounded by the four mounting holes, and the rotating arm 10 uses its own elasticity to adapt to the drilling operation of the mounting holes with different spacings.

[0066] The front side of the limiting cylinder 15 and the front side of the drill rod 9.1 are located on the same vertical plane. An insertion rod 22 is passed through the limiting cylinder 15, and the outer diameter of the insertion rod 22 is adapted to the drill rod 9.1. A handle 23 is vertically passed through the tail end of the insertion rod 22.

[0067] By providing the insert rod 22 and the handle 23, on the one hand, when adjusting the position of the drill assembly 9, the handle 23 is directly pulled, and a force is applied to the limit cylinder 15 through the handle 23 and the insert rod 22, and then the limit cylinder 15 is used to drive the rotating arm 10 to rotate, so as to unlock the chuck 6 and adjust the position of the drill assembly 9. On the other hand, starting from drilling the second mounting hole, the insert rod 22 can be inserted into the last mounting hole that has been drilled. At this time, the insert rod 22 cooperates with the limit cylinder 15, and uses the already drilled mounting hole to position the rotating arm 10 and fix the length of the rotating arm 10. Especially when the rotating arm 10 is located above the drill assembly 9 in the height direction, it can prevent the rotating arm 10 from being displaced under the action of eccentricity and vibration, and can prevent the mis-locking of the claw 7, thereby improving the stability of the equipment. In addition, since the length of the rotating arm 10 is fixed, the limiting cylinder 15 cannot be displaced in the strip groove 14 during the drilling process, and the distance between the drill bit assembly 9 and the limiting cylinder 15 can be fixed by limiting the limiting plate 13. At this time, the distance between the drill bit assembly 9 and the center of the limiting cylinder 15 is adapted to the distance between two adjacent preset mounting holes, thereby improving the drilling accuracy.

[0068] like Figure 2 , Fig. 9 and Fig.10 As shown, a force storage spring 24 is arranged between the tail end of the limit cylinder 15 and the tail end of the insertion rod 22, a second annular groove 25 is arranged on the surface of the limit cylinder 15, a second sleeve ring 26 is slidably arranged in the second annular groove 25, a through groove 27 is axially opened in the second annular groove 25, a slider 28 is slidably arranged in the through groove 27, the inner end of the slider 28 is fixedly connected to the insertion rod 22, the outer end of the slider 28 is fixedly connected to the inner surface of the second sleeve ring 26, and the outer diameter of the second sleeve ring 26 is matched with the limit cylinder 15. When the drill rod 9.1 moves forward and drills a hole, the limit plate 13 moves forward with the drill bit assembly 9 so that the strip groove 14 moves to the outside of the second sleeve ring 26.

[0069] When the drill bit assembly 9 is adjusted to the position of the next mounting hole to be drilled, the support plate 21 supports the limit plate 13 and the swing arm 10 is in a stretched state, so that the insertion rod 22 is at the position of the last drilled mounting hole. At this time, the elastic force of the force storage spring 24 causes the insertion rod 22 to automatically insert into the last drilled mounting hole.

[0070] During the drilling process, since the stop plate 13 is located outside the second ring 26, when the drill bit vibrates back and forth, the stop plate 13 uses friction to drive the second ring 26 to move forward and backward, and the force storage spring 24 allows the inserted rod 22 that has moved backward to be reinserted into the deepest displacement in the mounting hole, and prevents the inserted rod 22 from being pulled out of the mounting hole. At this time, the inserted rod 22 achieves the effect of secondary hole cleaning by moving back and forth and vibrating in the drilled mounting hole.

[0071] like Figure 2 and Fig.10 As shown, a cylindrical cavity 29 is provided at the front end of the insertion rod 22, a through hole 30 that coincides with the through groove 27 is provided on the side wall of the cylindrical cavity 29, and cutting teeth 31 distributed in a circular array are provided at the front end of the insertion rod 22.

[0072] During the drilling process, as the limit plate 13 drives the insertion rod 22 to vibrate back and forth, the cutting teeth 31 can cut the inner wall of the drilled mounting hole, and the debris formed by the cutting will enter the columnar cavity 29 and be discharged from the insertion rod 22 through the columnar cavity 29, the through hole 30 and the through groove 27.

[0073] like Figure 1 As shown, the slide 3 is provided with a handle 32 extending to the rear side of the motor 4, and the base 1 is provided with a running wheel 33. The handle 32 can more conveniently push the slide 3 forward and backward, and the running wheel 33 can facilitate drilling operations at different positions of the tunnel.

[0074] Among them, starting from drilling the second hole, since the insertion rod 22 is inserted into the previously drilled mounting hole, at this time, the insertion rod 22 can position the entire device to prevent the walking wheel 33 from rolling.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
