[0033] In order to better explain the present invention and facilitate understanding, the following Figure 1-4 , the utility model is described in detail through specific implementation methods. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is used as a reference.

[0034] Example:

[0035] Reference Figure 1-Figure 4 The embodiment of the utility model provides a bridge road maintenance and repair construction device, including a moving part 1, a drill bit 2 and a moving frame assembly 3, the moving part 1 is arranged on the moving frame assembly 3, and can slide along the moving frame assembly 3 in the X direction, the Y direction and the Z direction, the drill bit 2 is arranged on the moving part 1; it also includes a negative pressure device 4 arranged on the moving part 1, the negative pressure device 4 includes a dust collecting cover 41 and a negative pressure pump 42, the dust collecting cover 41 is directly or indirectly connected to the moving part 1, and is located outside the drill bit 2, the negative pressure pump 42 is connected to the dust collecting cover 41, so that when the negative pressure pump 42 generates negative pressure, negative pressure is also generated in the dust collecting cover 41; the negative pressure device 4 also includes a dust collecting box 45, the dust collecting box 45 is located upstream of the negative pressure pump 42, and is connected to the negative pressure pump 42 and the dust collecting cover 41 to collect dust.

[0036] In this embodiment, the moving part 1 is installed on the moving frame assembly 3, and the drill bit 2 used for repairing the pothole is installed on the moving part 1. Since the moving frame assembly 3 can adjust the position of the moving part 1 in the X-axis, Y-axis and Z-axis, the moving part assembly also realizes the three-axis adjustment of the working position of the drill bit 2. Therefore, the bridge and road maintenance and repair construction device in this embodiment provides a hardware foundation for the automated operation of the pothole repair process. Compared with the manual repair method, it can not only ensure that the repair efficiency is effectively improved, but also improve the pothole repair accuracy.

[0037] During the pit repair process, the negative pressure pump 42 works to generate negative pressure inside the dust hood 41, and the dust hood 41 itself is wrapped around the outside of the drill bit 2. Therefore, the dust generated by the drill bit 2 when working can be attracted into the dust hood 41 under the action of the negative pressure inside the dust hood 41, thereby avoiding the generation of a large amount of dust in this process.

[0038] Furthermore, the negative pressure device 4 is integrated as a whole on the moving part 1, which will not affect the smooth progress of the drilling work. Moreover, the dust collecting cover 41 can be set to a transparent material to improve the visibility of the drill bit 2 when repairing the pit.

[0039] Specifically, the negative pressure pump 42 can be configured as a centrifugal pump, and the dust collecting cover 41 can be configured as a transparent acrylic material.

[0040] The moving part 1 comprises a housing, and a rotating driving member arranged inside the housing and drivingly connected to the drill bit 2. The rotating driving member can be configured as a combination of a motor and a single gear ratio reduction box.

[0041] In this embodiment, the negative pressure device 4 further includes a dust collecting box 45 , which is located upstream of the negative pressure pump 42 and is in communication with the negative pressure pump 42 and the dust collecting cover 41 to collect dust.

[0042] In this embodiment, the dust box 45 is used to collect the dust entering the dust hood 41. The mixed gas mixed with dust will pass through the dust box 45 before flowing through the negative pressure pump 42. The dust will be filtered and stored in the dust box 45. The dust in the dust box 45 needs to be cleaned regularly.

[0043] In this embodiment, the negative pressure device 4 also includes an outer shell 49, which is connected to the moving part 1, the negative pressure pump 42 is located inside the outer shell 49, the dust box 45 is vertically slidably connected to the inside of the outer shell 49, and the upper part of the dust box 45 extends out of the outer shell 49; the outlet of the L-shaped tube 44 and the inlet of the negative pressure pump 42 are both provided with a socket 47, and both sides of the dust box 45 are provided with a socket 48 connected to the inner cavity of the dust box 45, and the corresponding sockets 48 can be squeezed with the corresponding sockets 47 to achieve the connection between the corresponding sockets 48 and the corresponding sockets 47; the sockets 48 and the sockets 47 both have inclined joint surfaces; the outer shell 49 is provided with an installation port, and the dust box 45 can be inserted into the outer shell 49 from the installation port.

[0044] In this embodiment, the housing 49 is detachably connected to the moving part 1 , and an opening is reserved at the top of the housing 49 to accommodate the insertion of the dust box 45 .

[0045] The internal structure of the dust box 45 is shown in the figure. By extending the flow length of the mixed gas and coordinating the serpentine-shaped baffles inside the dust box 45 to impact the mixed gas, large particles of dust can be deposited inside the dust box 45, thereby avoiding the generation of a large amount of dust.

[0046] At the same time, a spray device can be used to further reduce the amount of dust. Specifically, a spray pipe can be extended into the dust box 45. When the negative pressure pump 42 is working, the spray pipe is controlled to output water mist. In combination with the structure of the dust box 45 itself, the dust removal effect of the negative pressure device 4 can be further improved.

[0047] Sockets 48 are provided on both sides of the dust box 45, and the joint surfaces of the sockets 48 are connected to the joint surfaces of the corresponding sockets 47. Specifically, the two sets of joint surfaces can be set as inclined surfaces. Along the direction in which the dust box 45 is inserted into the outer shell 49, the corresponding joint surfaces are pressed against each other, and the corresponding sockets 48 and the sockets 47 are connected; along the direction in which the dust box 45 is separated from the outer shell 49, the corresponding joint surfaces are separated from each other, and the corresponding sockets 48 and the sockets 47 are separated from each other.

[0048] Specifically, the dust box 45 can be arranged to be vertically inserted into the housing 49, and the gravity of the dust box 45 itself can be used to press the two sets of joint surfaces against each other.

[0049] More specifically, a sub-magnetic point can be set at the bottom of the dust box 45, and a mother magnetic point that can be attracted to the sub-magnetic point can be set in the outer shell 49. The magnetic force between the two can not only improve the installation stability of the dust box 45 in the outer shell 49, but also improve the tightness of the pressing between the corresponding socket 48 and the corresponding socket 47.

[0050] The negative pressure device 4 also includes a telescopic assembly 43, which includes a telescopic rod 431 and a spring 432. The top of the dust hood 41 has a connecting flange, and the two ends of the telescopic rod 431 and the spring 432 are respectively connected to the connecting flange and the bottom of the moving part 1 to maintain a downward force on the dust hood 41.

[0051] In this embodiment, by setting up the telescopic component 43, it can be ensured that the lower end of the dust hood 41 can always be in contact with the ground. On the one hand, it can prevent debris from splashing during the operation of the drill bit 2. On the other hand, the relatively closed environment in the dust hood 41 is also conducive to improving the dust collection effect.

[0052] The telescopic rod 431 serves as a stroke limiting component for the dust collecting cover 41 to slide vertically relative to the moving part 1 , and the spring 432 serves as a downward force providing component for the dust collecting cover 41 .

[0053] The telescopic assembly 43 also includes an outer cover 433, the two ends of which are respectively connected to the connecting flange and the moving part 1, and the outer cover 433 wraps the telescopic assembly 43. The outer cover 433 can not only be used to provide protection for the telescopic rod 431 and the spring 432, but also improve the overall aesthetics of the telescopic assembly 43.

[0054] Specifically, the outer cover 433 may be configured as a corrugated rubber sleeve.

[0055] The dust collecting cover 41 is in the shape of a trumpet with an opening at the bottom, and the bottom of the dust collecting cover 41 has a transition portion A that curls upward and extends outward for contacting the ground.

[0056] In this embodiment, the dust hood 41 having a transition portion A that curls upward and extends outward is in the shape of a trumpet. When the transition portion A contacts the ground, it squeezes the dust hood 41 upward relative to the drill bit 2. At the same time, even if the flatness of the ground is poor, the transition portion A can reliably apply squeezing force from the ground to the dust hood 41, thereby improving the reliability of the device.

[0057] Specifically, the transition portion A and the dust collecting cover 41 are an integrated structure, and the portion thereof in contact with the ground may be reinforced, such as by additionally attaching a wear-resistant metal layer.

[0058] The moving frame assembly 3 includes a first frame 31, a second frame 32 and a third frame 33. The second frame 32 is slidably connected to the first frame 31 along the X direction, the third frame 33 is slidably connected to the second frame 32 along the Z direction, and the moving part 1 is slidably connected to the third frame 33 along the Y direction.

[0059] The movable frame assembly 3 also includes a first driving member, a second driving member 35 and a third driving member 36; the first driving member is supported on the first frame 31 and is drivingly connected to the second frame 32, so that the second frame 32 can slide along the X direction relative to the first frame 31; the second driving member 35 is supported on the second frame 32 and is drivingly connected to the third frame 33, so that the third frame 33 can slide along the Z direction relative to the second frame 32; the third driving member 36 is supported on the third frame 33 and is drivingly connected to the movable part 1, so that the movable part 1 can slide along the Y direction relative to the third frame 33.

[0060] The movable frame assembly 3 further includes a slide rail assembly 37 , and a sliding connection relationship is established between the first frame 31 and the second frame 32 , between the second frame 32 and the third frame 33 , and between the movable part 1 and the third frame 33 via the slide rail assembly 37 .

[0061] In this embodiment, the first driving member, the second driving member 35 and the third driving member 36 can all be set as a combination of a servo motor and a lead screw slider. When the servo motor drives the lead screw to operate, it will drive the slider to slide along the axial direction of the lead screw. The slider is the second frame 32, the third frame 33 and the moving part 1, and the slide rail assembly 37 serves as a connecting mechanism between the second frame 32 and the third frame 33, and between the moving part 1 and the third frame 33.

[0062] This type of moving part assembly can reliably and effectively realize the three-axis adjustment of the position of the moving part 1, thereby ensuring the flexibility of the drill bit 2 when performing the pit repair operation and improving the adaptability of the drill bit 2 to the pit shape.

[0063] The bridge and road maintenance and repair construction device also includes a construction vehicle, and the first frame 31 is connected to the rear of the construction vehicle.

[0064] Specifically, the rear of the construction vehicle is connected to the first frame 31, the second frame 32 can be configured as a gantry frame, and the third frame 33 can be configured as a long strip frame.

[0065] Since the first frame 31 is connected to the rear of the construction vehicle, the maneuverability of the bridge and road maintenance and repair construction device is effectively guaranteed, further improving the practical flexibility of the bridge and road maintenance and repair construction device.
