Description

Technical Field

[0001] This utility model relates to the technical field of construction equipment for the outer side of bridge railings, specifically a drilling device for a sliding cable protection pipe on the outer side of a bridge railing. Background Technology

[0002] In the field of highway electromechanical engineering construction, in order to ensure that various communication lines and cables can pass through the integral bridge, cable protection pipes need to be installed on the outside of the bridge railing. To install cable protection pipes on the outside of the bridge railing, drilling work needs to be carried out on the outside of the bridge. However, bridges are often elevated structures that span rivers, canyons, roads, etc., making it difficult to set up scaffolds on the outside of the bridge railing for the operation. If a bridge inspection vehicle is used for the operation, it involves the operation of a telescopic boom, which is more complicated and costly.

[0003] A patent application with application number CN202223530500.5 discloses a working platform on the outside of a bridge railing. Its main frame is a U-shaped frame structure, with vertical beams on both sides of the main frame positioned on either side of the bridge railing, and a horizontal beam on top of the U-shaped main frame. Rollers are installed on the vertical and horizontal beams to move along the surface of the bridge railing. A working platform is fixedly installed on one vertical beam (I) of the main frame, and a counterweight is fixedly installed on the other vertical beam (II). The working platform is located on the outside of the bridge railing, and the counterweight is located on the inside of the bridge railing. This patent allows workers to stand on the working platform on the outside of the bridge for drilling operations. It has a simple structure and low manufacturing and usage costs. However, because workers need to stand directly on the outside of the railing, it is considered high-altitude work, and even with safety ropes, there are still safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling device for cable protection pipes on the outside of a sliding bridge guardrail that does not require workers to operate at heights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drilling device for cable protection pipes on the outer side of a sliding bridge railing includes a horizontally arranged support truss. A connecting longitudinal frame is connected to the bottom outer side of the support truss, and an inner longitudinal frame is connected to the bottom inner side. A sliding frame is connected to the end of the connecting longitudinal frame, and a mounting platform is slidably connected within the sliding frame. An operating rod is hinged to the top inner side of the support truss, and the operating rod is connected to the mounting platform via a connecting rod. Sliding wheels are respectively provided on the support truss, the inner longitudinal frame, and the connecting longitudinal frame. Sliding grooves are provided on both inner sides of the sliding frame, and the outer side of the sliding frame is open. The mounting platform includes a mounting base, and sliders that mate with the sliding grooves of the sliding frame are provided on both sides of the mounting base.

[0007] Preferably, lifting screws are vertically installed at the four corners of the mounting base, and a mounting lifting platform is installed above the mounting base; the four corners of the mounting lifting platform are respectively provided with through holes that cooperate with the four lifting screws, and fastening nuts are provided above and below the through holes.

[0008] Preferably, both the mounting base and the mounting lifting platform are equipped with mounting plates, and a drilling machine is mounted on the mounting plates.

[0009] Preferably, a pair of control longitudinal frames are connected to both ends of the bottom outer side of the sliding frame, and a control crossbar is fixedly connected between the ends of the pair of control longitudinal frames; the connecting rod includes a connecting front rod that is rotatably connected to the operating lever, and a connecting rear rod that is rotatably connected to the end of the connecting front rod; the end of the connecting rear rod is rotatably connected to the control crossbar, and a connecting sleeve is sleeved on the middle section of the connecting rear rod.

[0010] Preferably, the outer side of the mounting platform is connected to the connecting sleeve via a hinge structure, and the hinge's rotation axis is horizontally set.

[0011] Preferably, the bottom end of the connecting longitudinal frame is provided with a lifting groove along the length direction, and the front two sides of the sliding frame are provided with lifting sliders that cooperate with the lifting groove; the top end of the connecting longitudinal frame is provided with multiple fixing holes evenly arranged along the length direction, and the rear two sides of the sliding frame are fixedly provided with fixing inclined plates, and the ends of the fixing inclined plates are fixedly connected to the fixing holes by bolts.

[0012] Preferably, the sliding wheel includes a pair of outer sliding wheels disposed on the outer side of the front end of the sliding frame, a pair of inner sliding wheels disposed on the inner side of the end of the inner longitudinal frame, and a pair of top sliding rollers disposed on the inner side of the support truss; the outer sliding wheels, inner sliding wheels and top sliding rollers all rotate laterally.

[0013] The beneficial effects of this utility model include:

[0014] This utility model adopts a structure in which a supporting truss, connecting longitudinal frame, and inner longitudinal frame cooperate to enclose the bridge railing. The operating rod is set at one end of the inner side of the supporting truss, and the drilling machine for drilling is set on the outer side of the bridge. This allows the operator to stand on the inner side of the bridge and control the drilling machine on the outer side of the bridge to perform drilling operations. The supporting truss, connecting longitudinal frame, and inner longitudinal frame are all equipped with a sliding wheel structure, which allows the device to slide along the bridge railing, making it easy to quickly adjust the drilling position.

[0015] This invention features an adjustable sliding frame structure. Both connection points between the sliding frame and the connecting longitudinal frame are vertically adjustable. Multiple fixing holes are arranged at the top of the connecting longitudinal frame. A fixing inclined plate at the outer end of the sliding frame is fixedly connected to these fixing holes using bolts. Adjusting the fixing holes changes the height of the sliding frame. The two front sides of the sliding frame are slidably connected to lifting grooves on the connecting longitudinal frame. Changing the fixing holes connected to the fixing inclined plate allows the lifting sliders on both front sides of the sliding frame to slide adaptively up and down within the lifting grooves, thus facilitating the adjustment of the sliding frame's height.

[0016] This utility model features a double-layer adjustable mounting platform. The lifting platform can be raised and lowered using four lifting screws and nuts. Since the screws and nuts are infinitely adjustable, the drilling machine can achieve more precise height adjustment, thereby improving the quality of drilling operations on the outside of bridges.

Detailed Implementation

[0022] The following is a further explanation of the present invention in conjunction with specific embodiments, such as... Figure 1 As shown, this embodiment is a drilling device for cable protection pipes on the outside of a sliding bridge railing, used in bridge construction for drilling operations during the installation of cable protection pipes on the outside of the bridge.

[0023] In this embodiment, a support truss 1 is provided, and a pair of top sliding rollers 11 are rotatably connected inside the support truss 1. A connecting longitudinal frame 2 is connected to the bottom front end of the support truss 1. The connecting longitudinal frame 2 is used to connect the sliding frame 3. A mounting platform 5 for mounting the drilling machine 6 is slidably provided on the sliding frame 3. By using control rods 4 that are respectively connected to the support truss 1 and the mounting platform 5, the mounting platform 5 can be controlled to slide back and forth along the sliding groove of the sliding frame 3, so as to drive the drilling machine 6 to slide back and forth, thereby realizing the function of drilling holes on the outer side of the bridge.

[0024] A pair of lifting grooves 21 are provided at the bottom end of the connecting longitudinal frame 2 along its length. Sliding blocks that cooperate with the lifting grooves are provided on both sides of the front end of the sliding frame 3. The sliding blocks can slide up and down within the lifting grooves 21. Figure 2 and Figure 3 As shown, fixed inclined plates 33 are fixedly connected to both sides of the rear end of the sliding frame 3. The top of the fixed inclined plate 33 can be fixedly connected to the fixed hole 23 at the top of the connecting longitudinal frame 2 by bolts. When it is necessary to adjust the height of the sliding frame 3, the position of the fixed hole 23 connected to the top of the fixed inclined plate 33 can be changed to allow the sliding frame 3 to rise and fall accordingly. When the sliding frame 3 rises and falls, the sliders on both sides of the front end will also rise and fall accordingly in the lifting groove 21.

[0025] like Figure 4 As shown, the mounting platform 5 comprises two parts: a mounting base 51 and a mounting lifting platform 52. Both sides of the mounting base 51 are equipped with slider structures that cooperate with the sliding frame 3, allowing it to slide back and forth along the sliding groove structure of the sliding frame 3. Lifting screws 53 are vertically fixed at each of the four corners of the mounting base 51. Through holes that cooperate with the lifting screws 53 are provided at each of the four corners of the mounting lifting platform 52, with the four lifting screws 53 passing through the four through holes respectively. By setting fastening nuts 54 on the lifting screws 53, the position of the mounting lifting platform 52 can be fixed, keeping the distance between it and the mounting base 51 constant. When it is necessary to adjust the height of the mounting lifting platform 52, only the positions of the four pairs of fastening nuts 54 cooperating with the mounting lifting platform 52 need to be changed.

[0026] Mounting plates 55 are fixedly installed on the top surfaces of both the mounting base 51 and the mounting lifting platform 52. The mounting plates 55 are used to fix the drilling machine 6. In this embodiment, the drilling machine 6 is fixedly installed on the mounting plate 55 using cable ties 61, thus achieving the fixed installation of the drilling machine 6. When the mounting platform 5 slides back and forth under the control of the control rod 4, it will also drive the drilling machine 6 to slide back and forth to achieve the purpose of drilling.

[0027] like Figure 2As shown, the control lever 4 comprises three parts: an operating lever 41 hinged to the top front surface of the supporting truss 1; a connecting front lever 42 hinged to the middle section of the operating lever 41; and a connecting rear lever 43 hinged to the end of the connecting front lever 42. A control longitudinal frame 31 structure is connected to the bottom rear end of the sliding frame 3, and a control crossbar 32 is connected between the two ends of the control longitudinal frame 31. The end of the connecting rear lever 43 is rotatably connected to the control crossbar 32. When the operator pushes the operating lever 41 back and forth, the control crossbar 32 can be driven to swing back and forth along the control crossbar 32. Figure 4 As shown, a connecting sleeve 44 is fitted on the connecting rear rod 43, and the connecting sleeve 44 can slide on the connecting rear rod 43; the connecting sleeve 44 is hinged to the rear side of the mounting lifting platform 52. When the connecting rear rod 43 swings back and forth, it will drive the mounting lifting platform 52 and the mounting base 51 to swing back and forth synchronously, so as to achieve the purpose of controlling the drilling machine 6 to move and drill holes through the operating rod 41.

[0028] In practical use, this embodiment first installs the drilling machine 6 onto the mounting plate 55, and then adjusts the position of the drilling machine 6 according to the construction drawings. First, a rough adjustment is made by changing the position of the fixing hole connected to the fixed inclined plate 33. Then, based on the difference between the height after the rough adjustment and the height data in the drawings, the height of the installation lifting platform 52 is adjusted to precisely match the height required by the construction drawings. The device can then be mounted on the bridge railing for operation. This device can not only install one drilling machine 6 for operation, but also install two drilling machines 6 on the mounting base 51 and the installation lifting platform 52 respectively to perform drilling operations on two holes simultaneously, thus doubling the work efficiency.

[0029] In this embodiment, a positioning plate is provided at the top centerline of the supporting truss 1, which can be used to position the lateral position of the drill bit of the drilling machine 6 to avoid skewed drilling position. When the device in this embodiment is installed on the bridge railing, the top sliding roller 11 contacts the top surface of the railing, the inner sliding wheel 13 contacts the inner side of the railing, and the outer sliding wheel 22 contacts the outer side of the railing, which can push the device to slide along the length of the bridge railing. When the device is in place, the drilling machine 6 is powered on and turned on. Pulling the operating rod 41 inward will drive the drilling machine 6 to slide horizontally inward. After contacting the outer side of the bridge, the drilling operation can be performed. After completing one drilling operation, pulling the operating rod 41 outward will retract the drilling machine 6 so that the device can be pushed to the next drilling point for the next drilling operation.

[0030] The above description is merely a further explanation of the present utility model in conjunction with specific embodiments. All descriptions made do not imply any limitation on the protection scope of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope of the claims.
