Description

Technical Field

[0001] This utility model relates to equipment for repairing steel bridge deck paving, and in particular to an intelligent cutting machine for repairing steel bridge deck paving. Background Technology

[0002] Nearly one hundred steel box girder bridges have been built and put into use in my country. During their use, various paving materials such as cast-in-place asphalt concrete and epoxy asphalt concrete have been used. Due to the large traffic volume in my country, heavy loads and overloading are frequent and increasing year by year. Most of the paving layers have suffered from serious fatigue cracks and high-temperature permanent deformation since they were opened to traffic, resulting in a shortened road life. Therefore, timely maintenance and repair of steel bridge deck paving is necessary.

[0003] The cutting machine is a commonly used tool for bridge deck pavement maintenance and repair. Its main function is to cut gaps on the bridge deck, which are thin lines with a depth of 100mm-400mm. The operator needs to hold the cutting machine firmly and cut along the pre-drawn cutting line on the bridge deck. The cutting machine consists of a stand and an electric saw blade, with a handle on the stand. When cutting, the electric saw blade needs to be started and adjusted to the set cutting depth. The operator then pushes the stand by holding the handle so that the electric saw blade cuts the bridge deck along the pre-drawn cutting line. Because the electric saw blade is exposed on the stand, the operator or people near the cutting machine are likely to touch the electric saw blade and be injured, resulting in low safety. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent cutting machine for repairing steel bridge deck paving. This intelligent cutting machine can avoid damage to operators caused by exposed cutting parts, thereby improving safety.

The bottom of the frame is provided with a cutting groove. When the lifting mechanism moves up and down, it can drive the cutting component to move up and down in the receiving space. The cutting end of the cutting component extends out or retracts into the receiving space through the cutting groove.

[0007] Based on the above technical solution, the present invention can be improved as follows:

[0008] Furthermore, the frame is provided with a partition that can divide the accommodating space into an installation chamber and a cutting chamber.

The cutting end of the cutting component passes through the clearance groove and is housed in the cutting chamber through the partition. When the lifting mechanism moves up and down, the cutting end of the cutting component can extend out of or retract into the cutting chamber through the clearance space formed by the clearance groove.

[0009] Furthermore, the frame includes a base plate, on the bottom surface of which a telescopic member is provided. A roller is provided at the bottom end of the telescopic member, which supports the base plate on the bridge surface.

[0012] Furthermore, the cutting component includes a stepper motor and a saw disc. The stepper motor is fixedly mounted on the mounting plate as the driving end. The output shaft of the stepper motor passes through the mounting chamber, through the clearance groove on the partition, and enters the cutting chamber. The output shaft can move along the Z-axis within the clearance groove. The saw disc is located in the cutting chamber as the cutting end and is connected to the output shaft of the stepper motor.

[0013] Furthermore, a dust collection component is also housed in the installation chamber, and a dust collection port communicating with the cutting chamber is provided on the partition plate. The dust collection component is connected to the dust collection port through a pipe.

[0014] Furthermore, the dust collection component includes a storage tank and a negative pressure pump. The suction end of the negative pressure pump is connected to the dust collection port through a pipe, and the discharge end of the negative pressure pump is connected to the storage tank through a pipe.

[0015] Furthermore, a control panel is provided on the top of the frame, and a position sensor is provided in the mounting chamber; the position sensor is used to acquire position data of the mounting plate moving along the Z-axis and transmit the position data to the control panel, and the control panel controls the lifting mechanism to perform lifting and lowering movements according to the position data to adjust the cutting depth of the cutting component.

[0016] Furthermore, a laser pointer is provided on the frame, which illuminates the bridge surface and forms a laser line on the bridge surface. The laser line coincides with the cutting path of the cutting end of the cutting component.

Detailed Implementation

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] See Figures 1 to 3 This embodiment relates to an intelligent cutting machine for repairing steel bridge deck pavement, including a movable frame, a lifting mechanism mounted on the frame that can be raised and lowered, a cutting component mounted on the lifting mechanism that can rotate and cut, and a housing 1 detachably mounted on a support body that can cover the lifting mechanism and the cutting component; a cutting groove 6 is provided at the bottom of the frame; the cutting component has a cutting end and a driving end that can drive the cutting end to cut in a rotating manner; the driving end of the cutting component can be raised and lowered relative to the frame along the Z-axis within the housing 1 via the lifting mechanism, and the cutting end of the cutting component can extend or retract from the frame through the cutting groove 6 provided at the bottom of the frame.

[0027] It should be noted that in this embodiment, the Z-axis is the axis perpendicular to the bridge deck, that is, the height direction of the frame; when the cutting component moves downward along the Z-axis, the cutting end of the cutting component extends out of the frame through the cutting groove 6 to cut the bridge deck; when the cutting component moves upward along the Z-axis, the cutting end of the cutting component retracts into the frame through the cutting groove 6 to avoid exposure and injury to the operator.

[0028] Specifically, the frame includes a base plate 2, rollers 3 mounted on the bottom surface of the base plate 2, and a support plate 4 mounted on the top surface of the base plate 2. The base plate 2 is a rectangular plate structure, and its length direction is the direction of movement of the cutting machine during cutting. Depending on actual needs, other base plates 2 suitable for installing lifting mechanisms and cutting components can also be used instead. Four rollers 3 are provided, and the four rollers 3 are located around the base plate 2, forming four force points on the base plate 2 to distribute the force evenly and increase the stability when moving along the cutting path. The rollers 3 are omnidirectional wheels in the prior art. The omnidirectional wheels are installed at the bottom of the base plate 2 to support the base plate 2 on the bridge deck. When supporting, a gap is formed between the base plate 2 and the bridge deck to avoid the bottom of the base plate 2 contacting the bridge deck and causing scratch damage.

[0029] The support plate 4 has an L-shaped plate structure, with a first plate segment 4a perpendicular to the base plate 2 and parallel to the length direction of the base plate 2, and a second plate segment 4b perpendicular to the base plate 2 and perpendicularly connected to one end of the first plate segment 4a; the lifting mechanism is located inside the first plate segment 4a of the support plate 4; the second plate segment 4b of the support plate 4 is located on one side of the length direction of the base plate 2, and a handle 5 is provided on the top outer side of the second plate segment 4b of the support plate 4. The handle 5 is used for the operator to grip and apply force to push the frame to move.

[0030] The housing 1 is detachably connected to the frame to form a closed accommodating space. The cutting groove 6 is located on the base plate 2 opposite to the cutting end of the cutting component and communicates with the accommodating chamber. The cutting component can be lifted and lowered along the Z-axis in the accommodating space by a lifting mechanism, and can extend or retract from the cutting end of the cutting component through the cutting groove 6 on the base plate 2.

[0031] The lifting mechanism includes two linear guide rails 7, an electric lead screw 8, and a mounting plate 9. The two linear guide rails 7 are spaced apart on the inner side of the first section 4a of the support plate 4 and are parallel to the Z-axis. A slider 7b is slidably connected to each linear guide rail 7. The electric lead screw 8 is located on the inner side of the first section 4a of the support plate 4 and between the two guide rails. A lead screw nut (not shown in the attached figure) is threaded onto the electric lead screw 8. The mounting plate 9 is a rectangular plate structure. The mounting plate 9 is parallel to the first section 4a of the support plate 4. The plate surface of the mounting plate 9 facing the first section 4a is the inner plate surface, and the plate surface of the mounting plate 9 facing away from the first section 4a is the outer plate surface. The inner plate surface of the mounting plate 9 is fixedly connected to the slider 7b of the two linear guide rails 7 and the lead screw nut of the electric lead screw 8, respectively. The outer plate surface of the mounting plate 9 is connected to the drive end of the cutting component.

[0032] By starting the electric lead screw 8 to rotate, the electric lead screw 8 engages with the lead screw nut threadedly, converting the rotational motion into axial motion. This causes the lead screw nut of the electric lead screw 8 to move along the axis of the electric lead screw 8, generating axial driving force. This force drives the mounting plate 9 to move along the linear guide rail 7, enabling the cutting component to rise and fall along the Z-axis. When the electric lead screw 8 rotates forward, the lead screw nut of the electric lead screw 8 moves upward along the axis of the electric lead screw 8, driving the mounting plate 9 to move upward along the linear guide rail 7. The cutting component then rises along the Z-axis to complete the retraction of the cutting end. When the electric lead screw 8 rotates in reverse, the lead screw nut of the electric lead screw 8 moves downward along the axis of the electric lead screw 8, driving the mounting plate 9 to move downward along the linear guide rail 7. The cutting component then descends along the Z-axis to complete the extension of the cutting end.

[0033] In this embodiment, the linear guide 7 is the linear guide 7 in the prior art, including a guide body 7a and a slider 7b slidably mounted on the guide body 7a. The guide body 7a is vertically fixed on the first plate segment 4a of the support plate 4 by bolts, and the slider 7b can slide along the guide body 7a. Stop blocks are provided at the top and bottom of the guide body 7a to prevent the slider 7b from disengaging from the guide body 7a when it moves. The stroke of the stop block on the guide body 7a is the stroke of the cutting component moving up and down along the Z-axis.

[0034] In this embodiment, the electric lead screw 8 is the electric lead screw 8 in the prior art, including a threaded rod 8a, a lead screw nut threadedly connected to the threaded rod 8a, and a servo motor 8b that drives and connects to one axial end of the threaded rod 8a; depending on the actual situation, other power components that can provide driving force to the mounting plate 9 can also be used to replace the electric lead screw 8; the stroke of the lead screw nut on the threaded rod 8a is the stroke of the cutting component moving up and down along the Z-axis.

[0035] During assembly, the threaded rod 8a is vertically mounted on the first section 4a of the support plate 4. The first section 4a has two bearing seats 10 on its inner surface, which can rotatably support the axial ends of the threaded rod 8a. Each bearing seat 10 has a shaft hole and a rolling bearing is installed in the shaft hole. The rolling bearing cooperates with the shaft end of the threaded rod 8a to reduce the resistance when the threaded rod 8a rotates and ensure smooth rotation. A gap is formed between the bottom end of the threaded rod 8a and the top surface of the base plate 2 to avoid contact wear between the threaded rod 8a and the top surface of the base plate 2 during rotation. The top end of the threaded rod 8a is connected to the output shaft of the servo motor 8b. The first section 4a of the support plate 4 has a motor frame on its inner surface that can fix and support the servo motor 8b.

[0036] Because the electric lead screw 8 drives the mounting plate 9, the movement position of the cutting component along the Z-axis can be precisely controlled to reduce the cutting depth error. It can also achieve self-locking to maintain the cutting depth of the cutting component during the cutting process, avoiding the cutting component from cutting the steel plate due to unstable manual operation, which would affect the fatigue life of the steel bridge deck. At the same time, with the guidance of two linear guide rails 7, the movement of the cutting component along the Z-axis can be guaranteed to avoid deviation.

[0037] A partition 11 is provided on the top surface of the base plate 2. The partition 11 is perpendicular to the base plate 2 and parallel to the first plate segment 4a of the support plate 4. The partition 11 divides the accommodating space into an installation chamber and a cutting chamber. A cutting groove 6 is opened on the base plate 2 and is connected to the cutting chamber. The lifting mechanism is located in the installation chamber. The fixed end of the cutting component is located in the installation chamber and is installed on the installation plate 9 in the lifting mechanism. The cutting end of the cutting component passes through the partition 11 and is placed in the cutting chamber. A clearance groove 12 is provided on the partition 11. The clearance groove 12 is used for the cutting end of the cutting component to pass through the partition 11 and for the cutting component to be able to move up and down along the Z-axis. The clearance groove 12 is an elongated groove structure. The clearance groove 12 is vertically arranged, and the length of the clearance groove 12 corresponds to the stroke of the cutting component moving up and down along the Z-axis.

[0038] The cutting components include a stepper motor 13 and a saw disc 14. The stepper motor 13 serves as the drive end and is fixedly mounted on the mounting plate 9 by bolts. The output shaft of the stepper motor 13 passes through the mounting chamber, through the clearance groove 12 on the partition plate 11, and enters the cutting chamber. The rotation axis of the output shaft is perpendicular to the first plate segment 4a of the support plate 4, and the output shaft can move along the Z-axis within the clearance groove 12. The saw disc 14 is the saw disc 14 in the prior art. The saw disc 14 serves as the cutting end and is placed in the cutting chamber to connect to the output shaft of the stepper motor 13.

[0039] When the stepper motor 13 starts, the output shaft of the stepper motor 13 rotates around the axis, generating a driving force to drive the saw disc 14 to rotate; when the mounting plate 9 moves along the Z-axis, it drives the stepper motor 13 to rise and fall accordingly on the Z-axis, so as to drive the saw disc 14 to extend or retract into the cutting chamber through the cutting groove 6 on the base plate 2; the length of the cutting groove 6 is greater than the diameter of the saw disc 14, and the width of the cutting groove 6 is greater than the thickness of the saw disc 14.

[0040] During cutting, the saw disc 14 extends only from the bottom end through the cutting groove 6 into the cutting chamber to cut into the bridge deck, while the rest of the saw disc 14 remains inside the cutting chamber. The saw disc 14 is only partially exposed in the gap formed between the base plate 2 and the bridge deck. This gap is small, making it difficult for the limbs and torso of the operator or personnel near the cutting machine to reach into it. Therefore, the exposed area of ​​the saw disc 14 during cutting is effectively reduced, preventing the operator or personnel near the cutting machine from touching the saw disc 14 and being injured. At the same time, as the saw disc 14 rotates, it can generate an airflow that flows from the outside of the gap through the cutting groove 6 and enters the cutting chamber. Under the action of this airflow, the smoke and gravel generated during cutting are concentrated in the cutting chamber, effectively reducing dust and gravel flying and injuring the operator or personnel near the cutting machine.

[0041] In this embodiment, the roller 3 and the base plate 2 are connected to each other by an electric telescopic rod 15. The electric telescopic rod 15 is the existing electric telescopic rod 15, which includes an outer rod body and an inner rod body movably sleeved in the outer rod body. The top end of the outer rod body is fixedly installed on the base plate 2, and the bottom end of the inner rod body is connected to the roller 3. The inner rod body can extend and retract axially relative to the outer rod body. By adjusting the extension amount of the inner rod body, the gap distance formed between the base plate 2 and the bridge deck is changed to adapt to the need for cutting non-straight bridge decks. Depending on actual needs, other suitable telescopic components that change the gap distance formed between the base plate 2 and the bridge deck can also be used instead of the electric telescopic rod.

[0042] The installation chamber also houses a dust collection component, and a dust collection port 21 is provided on the partition 11. The dust collection component is connected to the dust collection port 21 through a pipe. The dust collection component is used to suck up and collect the dust or gravel that enters the cutting chamber during cutting.

[0043] The dust collection component includes a storage box 16 and a negative pressure pump 17, which are fixedly installed on the top surface of the base plate 2. The suction end of the negative pressure pump 17 is connected to the dust collection port through a pipe, and the discharge end of the negative pressure pump 17 is connected to the storage box 16 through a pipe. The negative pressure generated by the negative pressure pump 17 is used to promptly suck in the dust or gravel in the cutting chamber and concentrate it in the storage box, so as to avoid the large accumulation of dust or gravel in the cutting chamber and affect the cutting.

[0044] A control panel 18 is also provided on the top outer side of the second plate segment 4b of the support plate 4, and a position sensor 19 is also provided on the inner plate surface of the first plate segment 4a of the support plate 4. The position sensor 19 is used to acquire the position data of the mounting plate 9 moving along the Z-axis and transmit the position data to the control panel 18. The moving position of the mounting plate 9 corresponds to the cutting depth of the saw blade 14, so that the operator can intuitively understand the cutting depth and control the start and stop of the electric screw 8 to make corresponding adjustments to adapt to the cutting of the bridge deck of the variable cross-section steel bridge. The control panel 18 can control the speed of the stepper motor 13 to adapt to the cutting of bridge decks of different materials. The control panel 18 can control the extension and retraction of the electric telescopic rod 15 to adjust the gap distance between the base plate 2 and the bridge deck. The control panel 18 can also control the output power of the negative pressure pump 17 to generate a suitable negative pressure to suck up dust or gravel.

[0045] A laser pointer 20 is provided at the other end of the base plate 2 along its length. The laser pointer 20 illuminates the bridge surface and forms a laser line on the bridge surface. The laser line coincides with the cutting path of the saw disc 14. During cutting, by holding the handle 5 and pushing the cutting machine, and aligning the laser line generated by the laser pointer 20 with the pre-drawn fixed cutting line on the bridge surface, the saw disc 14 can be guaranteed to cut the bridge surface along the pre-drawn fixed cutting line. Since the laser line generated by the laser pointer 20 is a thin and long beam, compared with the guide wheel used in the prior art, it can guide the cutting machine to cut more accurately, reduce cutting errors, and the laser line is bright and thin, making it easy for the operator to observe. The control panel 18 can control the laser pointer 20 to be turned on or off.

[0046] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
