[0015] The utility model discloses the following beneficial effects:
[0016] 1. By equipping the drill rod, internal expansion pipe, wedge, cutting hydraulic cylinder and cutting device on the same device at the same time, not only the types and quantities of field machinery are reduced, but also the cumbersome steps of frequent replacement or scheduling of different tools are avoided, and the cutting, drilling and crushing processes can be completed integrally, which can significantly shorten the construction period and improve the construction efficiency.
[0017] 2. The device can complete the cutting of the pavement around or the cutting line in the cutting mode, and then switch to the expansion crushing mode to crush and remove the target area. For the local overall plate replacement demand of the airport fast-drying cement concrete pavement, additional crushing hammer or electric grabber and other equipment are no longer needed, and the whole plate replacement process is compactly connected, and the efficiency is greatly improved.
[0018] 3. By using the tapered outer wall of the internal expansion pipe and the corresponding wedge to cooperate with each other, the expansion crushing of the pavement is realized. Compared with the common impact type crushing hammer or electric grabber, this kind of expansion crushing has almost no high-frequency vibration and metal knocking sound, the crushing efficiency is higher, and the noise is smaller, which is especially suitable for use in the airport environment with strict requirements on noise and vibration.
[0019] 4.

[0021] 6. The cutting device is equipped with a shell structure and forms a semi-closed working area under the premise of being connected with the external dust removal system, which can efficiently collect dust when the cutting blade is running. The greater the cutting depth, the more prominent the closed dust removal effect, which not only protects the health of the on-site construction personnel, but also better controls dust raising in environmentally sensitive areas (such as near airports).
[0022] 7. When the cutting hydraulic cylinder moves up, the bottom end of the shell will automatically fold and reset under the traction of the elastic rope, which saves additional manual intervention or complex recovery mechanisms, so that the device remains compact when not working, facilitating movement or expansion of other processes.
[0023] 8. The drilling and crushing parts are connected by sliding between guide columns and supports, and the cutting part is also based on double-cylinder double-rod synchronous motion. Multiple guiding and supporting structures make the device maintain good stability and durability in the process of high load and high intensity construction, reduce the failure rate and maintenance cost.

DETAILED DESCRIPTION
[0037] The technical solutions of the utility model will be clearly and completely described below in combination with the embodiments. Obviously, the described embodiments are only some of the embodiments of the utility model, but not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0038] It is explained that the orientation concepts of "left", "right", "up", "down", "front", "back", "inner" and "outer" in the following schemes are all relative directions, which will not be listed one by one.
[0039] Embodiment 1:
[0040] As shown in the figure, in the embodiment, the structure and working principle for drilling and breaking are mainly introduced to help quickly and more efficiently remove the local cement pavement that needs to be replaced. Figures 1 to 10
[0041] The airport quick-drying cement concrete pavement integral construction equipment disclosed in the embodiment comprises a drill rod 1, an inner expansion pipe 2 is fixedly connected to the outer end of the drill rod 1 at a position close to the bottom end, the outer end of the inner expansion pipe 2 is slidably connected with symmetrically arranged wedge blocks 3, the top end of the drill rod 1 is fixedly connected with a hydraulic motor 5 through a mounting head 4, a hydraulic cylinder 6 is installed at the top end of the hydraulic motor 5, a sliding block 7 is fixedly connected to the outer end of the hydraulic motor 5, the top end of the wedge block 3 is slidably connected with a hydraulic cylinder two 8, and the cylinder body of the hydraulic cylinder two 8 is fixedly connected with the sliding block 7; the cylinder body outer end of the hydraulic cylinder 6 is further fixedly connected with a support 9, and a connecting frame 10 is arranged on the support 9 for connection with an external driving device (such as an excavator).
[0042] In addition, in order to reduce dust during drilling, the outer ends of the symmetrically arranged wedge blocks 3 are slidably connected with a drill bit dust removal cover 11, which is connected with an external dust removal system through a pipeline, so that dust can be adsorbed during drilling. It should be noted that the support 9 is further fixedly connected with a cutting hydraulic cylinder 12 and subsequent cutting devices and the like, but in the embodiment, the main concern is the drilling and breaking function, so the cutting part is only briefly mentioned.
[0043] The conical structure is adopted on the outer wall of the inner expansion pipe 2, and the end with a larger diameter of the conical structure is close to the bottom end of the drill rod 1. Such design makes the inner expansion pipe 2 better cooperate with the wedge block 3 in the process of drilling and expansion breaking. The bottom end of the drill rod 1 is fixedly connected with a drill bit, and the diameter of the drill bit is equal to the diameter of the bottom end of the inner expansion pipe 2, so as to ensure the size matching in the drilling process. The inner wall of the wedge block 3 cooperates with the outer end of the inner expansion pipe 2. When the two wedge blocks 3 are completely closed, the distance between the outer ends of the two wedge blocks 3 is equal to the diameter of the bottom end of the inner expansion pipe 2, so as to ensure that the wedge block 3 closely fits the inner expansion pipe 2 in the initial state, and facilitates the subsequent breaking action.
[0044] In order to make the wedge block 3 move up and down more stably during construction, the top end of the hydraulic cylinder two 8 is further fixedly connected with a guide column 17. The outer end of the guide column 17 is in sliding connection with the support 9. During construction, the guide column 17 can play a guiding and stabilizing role whether in the process of moving up and down or in the stage of expanding and breaking the wedge block 3. In addition, the hydraulic cylinder 6 and the hydraulic cylinder two 8 are both double-acting hydraulic cylinders. The bidirectional output of the double-acting hydraulic cylinders can accurately control the movement trajectory and speed of the drill rod 1, the inner expansion pipe 2 and the wedge block 3, so as to improve the efficiency and accuracy of construction.
[0045] Working principle
[0046] Before formal construction, the connecting frame 10 is fixedly connected with an external driving device (such as an excavator), and the corresponding hydraulic and dust removal pipelines are connected. At this time, the drill bit dust cover 11 can be connected with an external dust removal system through a pipeline to provide dust removal conditions for subsequent drilling work.
[0047] When the equipment is in place, the hydraulic system of the external driving device is started, and the hydraulic motor 5 drives the drill rod 1, the inner expansion pipe 2 and the drill bit to move downward under the action of the hydraulic cylinder 6, so as to drill the cement pavement that needs to be removed. Since the diameter of the drill bit is the same as the diameter of the bottom end of the inner expansion pipe 2, the size accuracy of the hole can be ensured.
[0048] During the drilling process, the drill bit dust cover 11 closely covers around the drill bit, and the dust generated is timely sucked away through the connected dust removal system, which greatly reduces the dust amount on site. At the same time, the hydraulic cylinder 6 and the hydraulic cylinder two 8 are both double-acting settings. The bottom end of the drill bit dust cover 11 abuts against the ground during the drilling process, so that the drill bit dust cover 11 slowly slides upward. The posture of the drill rod 1 and the wedge block 3 can be flexibly controlled according to the need, so as to ensure the stability of the drilling depth and direction.
[0049] The drill bit dust cover is made of rubber and has elasticity.
[0050] When the drilling work is completed, the device enters the crushing stage, at this time, the wedge 3 is driven by the hydraulic cylinder two 8 to move downward, at the same time, the hydraulic cylinder two 8 piston rod is connected with the wedge 3 through the sliding groove on the wedge 3, and the hydraulic cylinder 6 drives the drill pipe 1 and the inner expansion pipe 2 to move upward in the opposite direction. Since the outer wall of the inner expansion pipe 2 is a tapered structure, the wedge 3 moves away from each other under the interaction of the inner expansion pipe 2 during the pressing process, and the inner expansion pipe 2 forces the two wedges 3 to move in the direction away from each other, which produces the effect of outward expansion, forcing the cement pavement to gradually break and crush. In this process, the drill bit dust cover 11 deforms elastically with the movement of the wedge 3.
[0051] Compared with the traditional electric grab or breaking hammer, the expansion and crushing mode of the wedge 3 and the inner expansion pipe 2 not only has higher efficiency, but also has lower noise, which is very suitable for construction occasions with high noise requirements such as airport pavement maintenance.
[0052] Through the expansion and crushing mode of the wedge 3 and the inner expansion pipe 2, the cement pavement can be broken more quickly and in a larger range. Compared with common electric grab, breaking hammer and other tools, the crushing efficiency is obviously improved.
[0053] The expansion and crushing process of the wedge 3 will not produce strong impact noise like traditional impact tools, which can significantly reduce noise pollution, and is especially suitable for construction of airport pavement with high noise requirements.
[0054] The drill pipe 1 is driven by the double-acting hydraulic cylinder 6, which can accurately control the drilling depth and direction without relying on the action of the excavator itself, greatly improving the construction quality and safety when replacing the plate.
[0055] Due to the connection of the drill bit dust cover 11 and the external dust removal system, the dust generated during drilling can be adsorbed and discharged in real time, reducing the dust content in the construction environment, ensuring the safety of the operator, and reducing the impact on the surrounding environment.
[0056] The double-acting design of the hydraulic cylinder 6 and the hydraulic cylinder two 8, combined with the sliding connection of the guide column 17 and the support 9, makes the whole drilling and crushing device have good guidance and stability during movement, which can reduce unnecessary impact or swing, thereby reducing the failure rate of the device.
[0057] In summary, the embodiment cooperates the inner expansion pipe 2 and the wedge 3, and under the bidirectional control of the hydraulic cylinder 6 and the hydraulic cylinder two 8, it can accurately and efficiently complete the drilling of the old cement pavement, and quickly crush the aging plate, thereby meeting the multiple requirements of efficiency, environmental protection and noise control during the overall plate replacement construction of the airport pavement. Through reasonable structural design and the assistance of the dust removal system, the reliability and environmental performance of the construction operation are greatly improved.
[0058] Embodiment 2:
[0059] As Figures 1 to 10 shown, the embodiment mainly aims at the cutting and cutting dust removal structure which is not fully explained in the foregoing embodiment 1, and focuses on the role of the cutting hydraulic cylinder 12, the cutting device and the cutting dust removal device in the airport pavement replacement construction. Embodiment 2 and embodiment 1 jointly constitute a multifunctional integrated construction equipment, which can cut the cement pavement that needs to be replaced, and then replace the old slab by means of drilling and breaking.
[0060] On the basis of the structure described in embodiment 1, this embodiment further illustrates the specific configuration and design advantages of the cutting hydraulic cylinder 12, the driving device 13, the shell one 14, the shell two 15 and the elastic rope 16 etc. fixedly connected on the support 9.
[0061] Two cutting hydraulic cylinders 12 are fixedly installed on the support 9. Each cutting hydraulic cylinder 12 is a double-acting hydraulic cylinder, has an independent piston rod, and is fixedly connected with the cutting device at the bottom end.
[0062] The double hydraulic cylinder arrangement can ensure better stability of the cutting device when exerting force on the cement pavement. It not only can push the cutting downward, but also can avoid the problems of left and right deviation and torsion that are prone to occur when cutting with a single cylinder.
[0063] The hydraulic rod bottom end of the cutting hydraulic cylinder 12 is fixedly connected with the driving device 13. The driving device 13 can be a motor, a hydraulic motor or other forms of power output components, which drives the cutting blade to rotate at high speed through the internal transmission mechanism.
[0064] The cutting blade is fixedly connected to the power output part of the driving device 13, which is used for cutting and grooving the cement pavement. In use, the cutting blade can be vertically adjusted by hydraulic control to meet the cutting requirements of different depths.
[0065] The cutting dust removal device includes the shell one 14 and the shell two 15 rotatably connected with the outer end of the driving device 13. The shell one 14 and the shell two 15 are both semicircular in cross section along the cutting blade plane. They are gradually separated from each other in the process of pressing down, so as to cover the cutting blade circumferentially.
[0066] In order to improve the dust removal effect in the cutting process, the shell one 14 is connected with the external dust removal system through a pipeline. When the cutting blade works, the shell one 14 and the shell two 15 can form a relatively closed space around them, so as to timely suck away the cutting dust generated, thereby greatly reducing the dust at the construction site and protecting the operator's vision and health.
[0067] When the hydraulic cylinder 12 moves to the upper limit position, the bottom ends of the shell one 14 and the shell two 15 are in contact with each other, and the elastic rope 16 is fixedly connected to the bottom ends.
[0068] The top end of the elastic rope 16 is fixedly connected to the support 9, and when the cutting hydraulic cylinder 12 drives the shell one 14 and the shell two 15 to move upward, the two semicircular shells can be automatically recovered and folded under the action of the elastic rope 16, so that the cutting device is in a compact state when not working, and dust and debris are prevented from scattering in the equipment.
[0069] Working principle
[0070] On the basis of the embodiment 1, the connecting frame 10 is connected to the external construction equipment (such as an excavator) and hydraulic pipelines and dust removal system pipelines, at this time, the cutting hydraulic cylinder 12, the driving device 13, and the shell one 14 and the shell two 15 are in the upper limit position, and the whole equipment looks compact and stable.
[0071] When the construction starts, the external driving equipment moves the equipment to above the target pavement, and then the piston rod of the cutting hydraulic cylinder 12 is controlled to synchronously extend downward, driving the driving device 13 and the cutting blade to gradually approach the ground.
[0072] When the cutting blade touches the surface of the cement pavement, the driving device 13 starts to rotate the cutting blade at high speed to cut and groove the pavement, and since the cutting hydraulic cylinder 12 is provided as a double hydraulic cylinder, the cutting blade always maintains a fixed direction when the two rods are synchronously pressed downward, so that the cutting surface is flat and accurate.
[0073] As the cutting blade moves downward, the shell one 14 and the shell two 15 gradually separate outward when contacting the ground, forming a semi-closed working space around the cutting blade to concentrate the collection of dust and debris generated during the cutting process.
[0074] During the cutting process, since the shell one 14 is connected to the external dust removal system through a pipeline, a large amount of dust generated can be timely sucked away, and the relative cooperation of the shell two 15 and the shell one 14 can effectively prevent the dust from spreading outward.
[0075] When the cutting reaches the target depth, the operator can control the hydraulic rod of the cutting hydraulic cylinder 12 to move upward, so that the shell one 14 and the shell two 15 gradually fold and reset to the initial position under the action of the elastic rope 16.
[0076] After the pavement around is completely cut, the drilling and wedge breaking mode described in the embodiment 1 can be switched to, and the cutting plate is locally broken and removed by the drill rod 1, the inner expansion pipe 2, and the wedge 3.
[0077] In use, the connecting frame 10 is fixedly connected with an external driving device, such as an excavator, and the device is used to replace the bucket of the excavator and is connected with corresponding pipelines;
[0078] Then the driving device 13 and the shell one 14 and the shell two 15 are moved downward by two cutting hydraulic cylinders 12 to cut the cement pavement, and the two cutting hydraulic cylinders 12 can ensure that the driving device 13 does not rotate during movement, so that the driving device 13 can cut the cement pavement in a fixed direction;
[0079] During the downward movement of the driving device 13, the shell one 14 and the shell two 15 are slowly opened under the action of the elastic rope 16, and when the cutting blades on the driving device 13 cut the cement pavement, the shell one 14 and the shell two 15 adsorb and remove the dust cut out, reducing the dust generated during cutting;
[0080] The cutting blades cut around the cement pavement that needs to be replaced, and then a drill bit on the inner expansion pipe 2 drills a hole at the position that needs to be replaced. During drilling, the hydraulic cylinder 6 drives the hydraulic motor 5, the mounting head 4, the drill rod 1 and the inner expansion pipe 2 to move downward, avoiding deviation of the drilling direction caused by adjusting the drilling depth by the excavator. During drilling, the drill dust cover 11 covers the drilling position and attracts the dust generated, reducing dust generation;
[0081] After drilling is completed, the corresponding wedge blocks 3 are driven downward by the hydraulic cylinder two 8, and the drill rod 1 and the inner expansion pipe 2 are moved upward by the hydraulic cylinder 6, so that the two wedge blocks 3 move in a direction away from each other to crush the cement pavement. Compared with ordinary electric hammers or breaking hammers, the expansion crushing by the two wedge blocks 3 is faster and produces less noise.
[0082] Since the cutting hydraulic cylinder 12 has a double hydraulic cylinder structure, the two piston rods apply force at the same time, avoiding the deflection and inclination of the cutting device caused by single-point force, so that the cutting blades cut the cement pavement more stably, efficiently and regularly.
[0083] Through the enclosing design of the shell one 14 and the shell two 15, and connecting the shell one 14 to an external dust removal system, dust can be immediately removed during cutting, which not only maintains the cleanliness around the construction area and reduces dust in the surrounding environment, but also ensures the clear vision of the operator and improves the safety of construction.
[0084] When the shell one 14 and the shell two 15 are at the upper limit, the bottom ends thereof contact each other and are connected to the support 9 through the elastic rope 16, which can automatically fold and reset when the cutting hydraulic cylinder 12 returns, ensuring the compactness of the cutting device and facilitating subsequent scene transfer or other process operations.
[0085] The embodiment is used in cooperation with the embodiment 1, the same equipment can integrate the cutting, drilling, crushing and dust removal functions, greatly simplifies the types and scheduling processes of the machines required by the airport pavement replacement construction, improves the on-site construction efficiency and reduces the operation cost.
[0086] Whether it is the shallow treatment only needing the surface cutting or the thicker airport pavement with deep cutting and crushing, the cutting device described in the embodiment and the drilling and crushing mechanism described in the embodiment 1 can be well competent, the adaptation range is wider and the construction process is flexible and adjustable.
[0087] In summary, the embodiment 2 makes a perfect structural design for the pavement cutting and cutting dust removal requirements, combines the drilling and crushing device described in the embodiment 1 and realizes the integrated construction process from the early cutting to the crushing and removal, provides an efficient, low-noise and environmentally friendly construction scheme for the airport fast-drying cement concrete pavement overall plate replacement.
[0088] The above only describes the preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein by the above teaching or related technical or knowledge, and the modification and change made by the person skilled in the art without departing from the spirit and scope of the present application should be within the protection scope of the claims attached to the present application.
