Description

Technical Field

[0001] The invention belongs to the technical field of bridge beam bottom drilling, and relates to a portable beam bottom vertical drilling machine, an application method and a bridge construction device thereof. Background Art

[0002] In the reinforcement construction of bridge beams, the installation of external prestressed steel strands requires vertical drilling in the anchorage area and cable clamps at the bottom of the beam. The traditional drilling method is usually done by workers using an impact drill to drill from bottom to top. Although this method is easy to operate, it is difficult to ensure that the drilling direction is perpendicular to the bottom of the beam during drilling, resulting in low hole position accuracy and unable to meet the requirements of the specification for the anchorage area drilling diameter of 31±1mm, depth of 230±2mm and verticality of ±1°. This lack of accuracy directly affects the subsequent vertical implantation of chemical anchors, thereby affecting the anchoring effect of the prestressed steel strands and the overall construction quality.

[0003] There are some simple beam bottom drilling devices on the market that are designed to improve the vertical accuracy and efficiency of drilling. However, these devices still have obvious limitations. First, it is difficult for workers to accurately control the drilling depth during operation, which can easily lead to drilling too deep or too shallow, thus affecting the anchoring quality. Second, the drilling efficiency of these devices is low and cannot meet the needs of large-scale construction. In addition, due to the limited space on the construction site, the existing drilling devices are not flexible enough and are difficult to move freely within the limited working area, further limiting their use in complex working conditions.

[0004] Announcement No. CN220409225U discloses a top plate drilling structure for building construction, which belongs to the field of building construction, including a bearing frame, an electric drill and a drilling auxiliary frame, the electric drill has a drill bit, and the drilling auxiliary frame is parallel to a bottom plate and a movable plate. The top plate drilling structure for building construction drives the slide bar to slide in the hole of the fixed block by pulling the positioning plate, so that the positioning plate fits with the side of the top plate, and the drilling auxiliary frame is kept parallel to the side of the top plate, which is convenient for controlling the drilling position and accuracy; by starting the electric drill and pressing it, the spring is compressed, and the movable plate is driven to move downward in the vertical direction as a whole, and the displacement is kept stable by the sliding connection between the movable plate and the two limit rods, until the bottom end of the drill bit passes through the positioning hole and contacts the upper end surface of the top plate to perform vertical drilling operation, which is convenient for vertical drilling and maintaining drilling accuracy, avoiding drilling tilt during manual drilling, and improving the efficiency and accuracy of drilling construction.

[0005] Announcement No. CN219926527U discloses a vertical drilling device for concrete blocks, comprising: a bracket, on which a test block layer is provided for placing concrete blocks, a pressing mechanism is provided above the test block layer for fixing the concrete blocks, and the test block layer is provided with a through hole corresponding to the position of the concrete block to be drilled; an impact drill, which is installed on the bracket and located below the test block layer; a drill guide sleeve, which is provided on the lower side of the test block layer and provided with a guide hole corresponding to the through hole to guide the drill bit of the impact drill to drill vertically upward. The drilling device provides a drill guide sleeve below the concrete block to drill upward from the bottom of the concrete block, so as to solve the technical problems of the prior art that the drilling hole position is not vertical to the concrete block and the floating dust in the hole position is difficult to discharge.

[0006] Announcement No. CN212822884U discloses a movable lifting device for embedding reinforcement at the bottom of a structural column beam, comprising: a mobile platform arranged in a horizontal direction; a first telescopic rod arranged in a vertical direction, and its lower end is connected to the middle part of the side surface of the mobile platform; the middle part of the main transmission lever is rotatably connected to the upper end of the first telescopic rod; a second telescopic rod is arranged in a vertical direction and is relatively parallel to the first telescopic rod, and the middle part of the second telescopic rod is rotatably connected to the first end of the main transmission lever; a fixing device is arranged at the upper end of the second telescopic rod, and the fixing device is used to place an electric impact drill. By setting up a mobile platform and setting the first telescopic rod on the mobile platform, the first telescopic rod is rotatably connected to the second telescopic rod through the main transmission lever, and an electric impact drill is arranged on the fixing device to perform the bottom beam drilling operation, it is possible to avoid setting up scaffolding or gantry frames for embedding reinforcement operations, greatly saving construction time, saving manpower, greatly improving construction efficiency, and saving construction costs.

[0007] However, the above-mentioned prior art has the problems of being unable to accurately grasp the drilling depth, and being unable to automatically adapt to the shape of the beam bottom to ensure a tight connection between the device and the beam bottom, and being unable to move and adjust the position within the limited space of the beam bottom. Therefore, a portable vertical drilling machine for the bottom of the beam for bridge construction is proposed.

[0008] In summary, the shortcomings of the existing technology are mainly reflected in poor vertical drilling accuracy, inaccurate depth control, low drilling efficiency and inconvenient device disassembly, which have an adverse impact on the construction quality and efficiency of bridge reinforcement projects.

[0022] The first mounting block (2) serves as the core connection part of the base guide block mechanism (1) and is mainly used to fix other components.

[0023] The first gear (3) is installed inside the base guide block mechanism (1) and meshes with the rocker (4) and rack (5) system to convert the manually applied rotational force into the up and down linear motion of the rack (5).

[0024] The rocker (4) drives the first gear through rotational motion, so that the rack (5) system can move up and down. The operator adjusts the drilling depth by manually rotating the rocker (4).

[0025] The rack (5) is an important component in the base guide block mechanism (1) that converts the rotational motion of the gear into linear motion. The rack (5) meshing with the first gear (3) is responsible for driving the entire drilling system to move in the vertical direction.

[0026] The scale (16) is located on the base guide block mechanism (1) and is mainly used to accurately indicate the vertical movement distance of the device. Through the scale, the operator can monitor the drilling depth in real time.

[0027] The indicator plate (17) is used in conjunction with the scale (16) to display the vertical position of the current device. The pointer on the indicator plate (17) can accurately point to the scale on the scale (16), helping the operator to determine the drilling position and depth, thereby effectively improving the construction accuracy.

[0028] The second rack (18) and the second gear (19) are meshed with each other, which can provide a faster threaded rod fixing method for the drilling semi-arc clamping plate mechanism. Only one side of the second gear (19) needs to be rotated to drive it, so that the electric drill for drilling, which originally required the rotation of two second gears (19), can be fixed. The fixing speed is faster and the disassembly time is saved.

[0029] The design of the second gear (19) can provide stronger support and balance for the base guide block mechanism (1), ensuring smoother movement in the vertical direction without causing movement deviation due to unbalanced load.

The bottom of the placement frame is connected to the base guide block mechanism and can be adjusted up and down according to the drilling needs to adapt to the construction requirements of different heights and positions.

[0033] The threaded rod (7) is a key component in the semi-arc-shaped drilling clamp mechanism (8) for fixing the electric drill. It provides a stable locking force through a spiral structure to firmly fix the electric drill in the placement frame, ensuring that no displacement or loosening occurs during the drilling process.

[0034] See also Figure 4 and Figure 5 The clamping slide rail moving mechanism (10) comprises a mounting plate (9), a push plate (101), a spring (102), a first hinge plate (11), a second hinge plate (12), a slide rail (13), a clamping block (14) and a bolt (15); the push plate (101) cooperates with the slide rail (13) via the clamping block (14) so ​​that the clamping slide rail moving mechanism (10) can form a firm and tight connection with the bottom of the beam.

[0035] The mounting plate (9) is the basic structure of the entire clamping slide rail moving mechanism (10), and its main function is to firmly connect other components such as the push plate (101), the slide rail (13), the hinge plate (11), etc.

[0036] The push plate (101) is a dynamic component in the clamping slide rail moving mechanism (10), and is mainly used to push the clamping block (14) to form a close contact with the bottom of the beam. The push plate (101) can adapt to the shape and thickness changes of the bottom of the beam through the reaction force provided by the spring (102) installed behind it, thereby realizing the function of automatic adjustment.

[0037] The spring (102) is installed between the push plate (101) and the first hinge plate (11), and its main function is to provide a reaction force so that the push plate (101) can maintain a continuous pressing force on the bottom of the beam, thereby enhancing the fit between the device and the bottom of the beam.

[0038] The first hinge plate (11) is a component installed behind the push plate (101) and is used in conjunction with the spring (102) and the second hinge plate (12) to ensure that it can fit well with the bottom of the beam during installation, thereby improving the overall stability of the device.

[0039] The second hinge plate (12) cooperates with the first hinge plate to further enhance the flexibility and stability of the device, so that the push plate (101) and the clamping block (14) can better adapt to the inclination and irregular surface of the bottom of the beam during installation.

[0040] The slide rail (13) is a component in the entire clamping slide rail moving mechanism (10) used to guide the movement of the push plate (101) and the clamping block (14), so that the push plate (101) can move smoothly along the direction of the slide rail (13), thereby achieving a clamping operation on the bottom of the beam.

By rotating the bolts, the position of the clamping block can be fine-tuned so that the clamping block can fit more accurately with the bottom of the beam.

[0043] Working principle of the present invention: Figure 1 and Figure 4The working principle of the portable vertical punching machine for the bottom of the beam for bridge construction of the present invention is as follows. The base guide block mechanism 1 drives the rack 5 system to move up and down through the rocker 4, thereby realizing the vertical adjustment of the entire punching device. The drilling semi-arc clamping plate mechanism 8 fixes the electric drill in the placement frame 6 through the threaded rod 7 to ensure that the electric drill will not shift or loosen during operation. The clamping slide rail moving mechanism 10 cooperates with the push plate 101 and the spring 102 to enable the clamping block 14 to automatically adapt to the shape and thickness changes of the bottom of the beam, thereby achieving a firm clamping effect. At the same time, the bolt 15 can fine-tune the position of the clamping block 14 to further improve the fit with the bottom of the beam.

[0044] See also Figure 1 and Figure 2 and Figure 6 and Figure 7 The rotation of the rocker 4 drives the first gear 3, thereby moving the rack 5 in the vertical direction. The scale 16 is mounted on the base guide block mechanism 1, and cooperates with the indicator plate 17 to help the operator monitor the vertical position and drilling depth of the device. The second gear 19 plays a supporting and balancing role in the gear system to ensure the stability of vertical movement. In addition, the design of the moving wheel 20 allows the device to be freely moved and adjusted when not drilling, which greatly improves the convenience of operation.

[0045] See also Figure 2 and Figure 3 The placement frame 6 provides a stable support for the electric drill to ensure that it remains fixed during drilling. The locking force applied by the threaded rod 7 through rotation prevents the electric drill from being displaced or loosened during operation, thereby ensuring the stability and accuracy of drilling.

[0046] See also Figure 4 and Figure 5 The push plate 101 provides continuous clamping force under the action of the spring 102 to ensure that the clamp block 14 is in close contact with the bottom of the beam. The design of the slide rail 13 allows the push plate 101 to move smoothly, thereby achieving a clamping operation. The mounting plate 9 serves as the basis for the clamping slide rail moving mechanism 10 and connects all major components. The combination of the first hinge plate 11 and the second hinge plate 12 provides good adaptability and flexibility, so that the push plate 101 and the clamp block 14 can adapt to the inclination and irregular surface of the bottom of the beam.

[0047] The present invention can achieve precise control of the drilling depth through the precise vertical adjustment and scale indication of the base guide block mechanism, effectively improving the accuracy and consistency of construction to improve the construction accuracy; the drilling semi-arc clamping plate mechanism realizes stable fixation of the electric drill through the placement frame and the threaded rod to ensure that no displacement occurs during the drilling process; at the same time, the design of the clamping slide rail moving mechanism enables the device to automatically adapt to the shape of the beam bottom, thereby ensuring a close connection between the device and the beam bottom; the design of the moving wheel enables the device to be conveniently moved and adjusted in position at the construction site, thereby improving the flexibility and convenience of construction; in addition, the cooperation of the rocker and the rack allows the operator to quickly set the drilling depth through manual adjustment, further improving the construction efficiency.

An application method of a portable beam bottom vertical punching machine, the method is based on the portable beam bottom vertical punching machine according to claim 2, and is characterized by: (1) The base guide block mechanism drives the rack system to move up and down through the rocker to achieve vertical adjustment of the entire punching device; the drilling semi-arc clamping plate mechanism fixes the electric drill in the placement frame through the threaded rod to ensure that the electric drill will not shift or loosen during operation; the clamping slide rail moving mechanism cooperates with the push plate and spring to enable the clamping block to automatically adapt to the shape and thickness changes of the beam bottom, thereby achieving a firm clamping effect; at the same time, the bolt can fine-tune the position of the clamping block to further improve the fit with the beam bottom; (2) The combination of the first hinge plate and the second hinge plate provides good adaptability and flexibility, so that the push plate and the clamping block can adapt to the inclination and irregular surface of the bottom of the beam; (3) The semi-arc clamping plate mechanism for drilling achieves stable fixation of the electric drill through the placement frame and threaded rod, ensuring that no displacement occurs during the drilling process. At the same time, the design of the clamping slide rail moving mechanism enables the device to automatically adapt to the shape of the bottom of the beam, thereby ensuring a tight connection between the device and the bottom of the beam.
