Description

Technical Field

[0001] This application relates to the technical field of concrete processing devices, and in particular, to a drilling device and construction method for reinforced concrete precast components. Background Art

[0002] With the acceleration of the urbanization process, the scale of construction continues to expand. Due to problems such as low efficiency, large quality fluctuations, and serious environmental pollution in the traditional in-situ concrete construction method, it has been difficult to meet the development needs of modern building industrialization. In this context, reinforced concrete precast components, with their advantages of standardized and mechanized production, have become a key technology to promote the transformation of building industrialization. Small precast components are prefabricated in the factory and then transported to the site for assembly, which not only improves the construction efficiency but also significantly enhances the building quality.

[0003] However, before assembling small precast components, in order to ensure the stable connection of adjacent components, through holes need to be pre-opened on the precast components so as to achieve rapid assembly through fasteners such as screws and bolts. Currently, automatic concrete drilling machines are generally used in the industry for hole-opening operations.

[0004] However, such equipment has obvious limitations: it can only perform hole-opening on a single side of a small precast component in a single processing. When it is necessary to open holes on two vertically adjacent sides simultaneously, it is necessary to repeatedly position the small precast component and complete the processing in two steps, resulting in a significant decrease in production efficiency. Specifically, repeated positioning not only increases the operation complexity but also may cause hole position deviation due to positioning errors, affecting the assembly accuracy of small precast components. In addition, the step-by-step processing prolongs the production cycle, reduces the equipment utilization rate, increases the labor and time costs, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a drilling device and construction method for reinforced concrete precast components to solve the problem of low efficiency when the above-mentioned hole-opening equipment processes holes on two vertical surfaces of concrete components.

[0006] In the first aspect, a drilling device for reinforced concrete precast components provided by this application adopts the following technical solution: A drilling device for reinforced concrete precast components includes a base, on which there are clamping members for clamping and fixing precast components and hole-opening members for hole-opening processing of precast components; the hole-opening members include two groups of drills arranged horizontally above the base and perpendicular to each other, and a power source for driving the drills to rotate; a moving member for reciprocally sliding the power source in three directions (up and down, front and back, and left and right) is provided on the upper side of the base.

[0007] By adopting the above technical solution, on the one hand, two groups of mutually perpendicular drill bits can simultaneously perform hole opening on two vertical surfaces of the prefabricated component, avoiding the drawbacks of traditional equipment that requires repeated positioning and step-by-step processing, greatly improving the production efficiency, shortening the production cycle, and reducing the labor and time costs. On the other hand, the moving part enables the power source to reciprocally slide in three directions: up and down, front and back, and left and right. It can flexibly adjust the position of the drill bit according to the size of the prefabricated component and the hole opening position, improving the accuracy and flexibility of hole opening, reducing the hole position deviation caused by positioning errors, and ensuring the assembly accuracy of the prefabricated component.

[0008] Optionally, the clamping part includes two clamping plates that relatively slide on the upper side of the base platform, and two first electric cylinders fixed on the base platform. The telescopic rods on the two first electric cylinders are respectively fixedly connected to the mutually remote sides of the two clamping plates.

[0009] By adopting the above technical solution, driven by the two first electric cylinders, a movement of approaching or separating from each other can be achieved. When it is necessary to clamp the prefabricated component, the telescopic rods of the first electric cylinders extend, pushing the clamping plates to move towards the prefabricated component until it is tightly clamped, ensuring the stability of the prefabricated component during the hole opening process and avoiding the hole opening deviation caused by the shaking of the component. At the same time, this clamping method has strong versatility and can adapt to prefabricated components of different sizes. Only by adjusting the stroke of the first electric cylinder can the position of the clamping plate be changed, without the need to replace special fixtures, improving the flexibility and applicability of the device and reducing the production cost.

[0010] Optionally, the moving part includes two first cylinders fixedly arranged on the upper side of the base platform in the vertical direction, a support crossbeam located above the first cylinders, and the lower sides of both ends of the support crossbeam are fixedly connected to the upper ends of the two first cylinders; a support plate slides on the support crossbeam, and a first driving source for driving the support plate to slide is fixedly arranged; a base plate is arranged on the upper side of the support plate, the power source is located above the base plate, and the drill bit is located on the vertical side of the power source close to the clamping part; a second driving source for reciprocally sliding the power source is fixedly arranged on the base plate, the support plate reciprocally slides along the length direction of the support crossbeam, and the sliding directions of the support crossbeam, the power source, and the support plate are mutually perpendicular.

[0011] By adopting the above technical solution, the first cylinders arranged in the vertical direction can drive the support crossbeam to move up and down, realizing the position adjustment of the drill bit in the vertical direction; the first driving source on the support crossbeam drives the support plate to slide, enabling the drill bit to move in the front and back directions; the second driving source on the base plate can also make the power source and the drill bit slide left and right. In this way, through the coordinated cooperation of the driving sources in three directions, the position of the drill bit can be flexibly and accurately adjusted to meet the hole opening requirements of prefabricated components at different positions and sizes, greatly improving the flexibility and adaptability of hole opening.

[0012] Optionally, a steel hoop is embedded on the inner wall of the hole opened on the prefabricated component, and a clamping member for clamping the steel hoop so that it is embedded in the hole opened on the component is provided on the support plate.

[0013] By adopting the above technical solution, a steel hoop is embedded in the inner wall of the hole of the prefabricated component, which can significantly enhance the strength and stability of the hole, avoid cracking and damage of the hole wall due to the reduction of local strength of concrete after the hole is opened, extend the service life of the prefabricated component, and ensure the safety of the building structure. A clamp is set on the support plate, which can accurately clamp the steel hoop before opening the hole to ensure that it is accurately embedded in the hole of the prefabricated component, effectively prevent the steel hoop from shifting and loosening during the installation process, and ensure the installation quality. At the same time, this design enables the installation of the steel hoop and the hole opening operation to be integrated on the same device, which improves the continuity and efficiency of the construction, reduces the cumbersome operation and time waste caused by the dispersion of the process, and reduces the labor cost.

[0014] Optionally, a receiving box for placing the steel ferrule is installed on the upper side of the end of the supporting crossbeam, and a material taking port for inserting a clamp and clamping the steel ferrule is opened on the lower side of the receiving box facing the base plate.

[0015] By adopting the above technical solution, a storage box is installed on the upper side of the end of the supporting crossbeam, providing a special storage location for the steel ferrule, making the placement of the steel ferrule more orderly and standardized, convenient for operators to manage and use, and improving the cleanliness and work efficiency of the construction site. A material extraction port is opened on the lower side of the storage box facing the base plate, so that the clamp can be directly inserted from the material extraction port and clamp the steel ferrule, realizing the automatic extraction of the steel ferrule, reducing the links of manual handling and placement of the steel ferrule, reducing labor intensity, and improving the degree of automation of the construction. At the same time, the design organically combines the storage of the steel ferrule with the drilling device, making the entire construction process more compact and coherent, and reducing construction pauses caused by untimely supply of steel ferrules.

[0016] Optionally, a clearance gap is provided on the inner wall of the feeding port, a limiting spring piece is fixedly provided on the inner wall of the clearance gap, and an elastic protrusion is fixedly provided on the limiting spring piece to prevent the steel sleeve from escaping from the feeding port in a natural state.

[0017] By adopting the above technical solution, the elastic protrusions provided on the limiting spring pieces can block the steel hoop in a natural state, effectively preventing the steel hoop from falling out of the material taking port due to its own gravity or slight vibration, ensuring the stable storage of the steel hoop in the storage box, avoiding the steel hoop from being scattered and lost, and ensuring the normal supply of construction materials. When the clamping part needs to clamp the steel hoop, the clamping part can easily overcome the resistance of the elastic protrusion and take out the steel hoop without affecting the normal construction operation.

[0018] Optionally, the substrate is rotatably mounted on the upper side of the support plate, and a third driving source for controlling the rotation of the substrate is fixedly provided on the bottom side of the support plate; the clamping member includes a pneumatic gripper located above the substrate and a fourth driving source fixedly provided on the upper side of the substrate and used for driving the pneumatic gripper to slide reciprocally; the sliding direction of the pneumatic gripper is perpendicular to the length direction of the drill bit.

[0019] By adopting the above technical solution, the pneumatic gripper slides reciprocally on the substrate through the fourth driving source, and the sliding direction is perpendicular to the length direction of the drill bit, further expanding the movement range of the pneumatic gripper, enabling it to accurately reach the material taking port position to clamp the steel sleeve hoop and accurately place it into the hole of the precast member. This design organically combines various movement modes such as rotation and sliding, realizes the multi-dimensional flexible movement of the pneumatic gripper, improves the clamping and installation efficiency of the steel sleeve hoop, ensures the smooth progress of the construction, and provides strong support for the efficient construction of reinforced concrete precast members.

[0020] Optionally, a vertically upward second cylinder is fixedly provided on the bottom side of the support plate, the hydraulic rod of the second cylinder is vertically upward, and a locking rod is coaxially fixedly provided at the end of the hydraulic rod; a locking through hole is provided on the support plate, and a plurality of locking slots capable of coinciding with the locking through hole are provided on the bottom side of the substrate; the locking rod penetrates through the locking through hole and is inserted into the corresponding locking slot when the drill bit drills the precast member and installs the steel sleeve hoop.

[0021] By adopting the above technical solution, when the drill bit drills the hole and installs the steel sleeve hoop, the locking rod accurately penetrates through the locking through hole of the support plate and is inserted into the locking slot on the bottom side of the substrate, forming a rigid mechanical locking. This design effectively restricts the rotational freedom of the substrate, eliminates the deviation of the substrate caused by the impact force of the drill bit or the vibration of the equipment, and ensures the positioning accuracy of the drill bit and the steel sleeve hoop.

[0022] Optionally, a guiding inclined surface is provided at the edge of the end of the locking rod away from the second cylinder.

[0023] By adopting the above technical solution, when the locking rod is inserted into the locking slot, the vertical insertion action can be converted into a horizontal fine adjustment through the inclined surface structure, automatically calibrating the relative position deviation between the locking rod and the slot. Even if the substrate has a slight deviation due to processing errors or vibrations, the inclined surface can still guide the locking rod to smoothly slide into the slot, avoiding equipment damage caused by jamming or collision.

[0024] In the second aspect, the construction method of a drilling device for reinforced concrete precast members provided by the present application adopts the following technical solution: A construction method of a drilling device for reinforced concrete precast members, adopting the above-mentioned drilling device for reinforced concrete precast members, specifically includes the following steps: Step 1: Place multiple steel sleeves in the accommodation box in advance, then place the precast component to be drilled on the base through a crane, and clamp it with a clamping part. Step 2: Adjust the positions of the two drill bits through the moving part according to the drilling positions, and then drive the drill bits to rotate through the power source to drill the precast component. Step 3: First, reset the drill bits, then slide the support plate along the support beam, take out the steel sleeve in the accommodation box from the material taking port through the clamping part on the base plate, then rotate and adjust the base plate through the third driving source, and drive the pneumatic gripper to act through the fourth driving source to embed the steel sleeve clamped by the pneumatic gripper into the drilled hole.

[0025] Step 4: The pneumatic gripper resets, and the base plate rotates and resets, and so on in a cycle.

[0026] By adopting the above technical solutions, the labor intensity is reduced, the construction continuity is improved, and at the same time, the positioning deviation caused by manual operation is reduced, ensuring the verticality and tightness of the installation of the steel sleeve, providing a reliable guarantee for the high-quality production of precast components.

[0027] In summary, the present application includes the following beneficial technical effects: On the one hand, two groups of mutually perpendicular drill bits can simultaneously drill two vertical surfaces of the precast component, avoiding the disadvantages of traditional equipment that requires repeated positioning and step-by-step processing, greatly improving the production efficiency, shortening the production cycle, and reducing the labor and time costs. On the other hand, the moving part enables the power source to reciprocate and slide in three directions of up and down, front and back, and left and right, and can flexibly adjust the position of the drill bit according to the size and drilling position of the precast component, improving the drilling accuracy and flexibility, reducing the hole position deviation caused by positioning errors, and ensuring the assembly accuracy of the precast component.
