Description

Technical Field

[0001] The utility model belongs to the technical field of aerated concrete block production, and more specifically relates to a hand-held hole-opening device for a concrete blank. Background Art

[0002] As an innovative and energy-saving building wall material, aerated concrete blocks / sheets have been proven in many engineering practices to have the advantages of light weight, high strength, waterproof and flame retardant, sound insulation and heat preservation, safety, environmental protection and high plasticity. Based on siliceous and calcium materials, aerated agents are added, and the ingredients are prepared and poured according to the characteristics of the raw materials. After the processes of steel bar meshing, static curing and gasification, demoulding and cutting, high-pressure steam curing, etc., porous and lightweight aerated concrete blocks / sheets are formed.

[0003] At present, the autoclaved concrete blocks are still mainly carried manually when in use. In order to facilitate the handling operation of the autoclaved concrete blocks, it is generally necessary to process hand-held holes and grooves on the blocks.

[0005] Patent CN212888302U discloses a concrete slab grooving device for a concrete slab crosscutting machine. The grooving device in the application can scrape the sides of the concrete block during the crosscutting process of the concrete slab; at the same time, it can grooving grooves on both sides of the concrete block that are lower than the middle, thereby increasing the fulcrum points and facilitating transportation.

[0006] Although the above-mentioned applications are all capable of realizing automatic grooving of autoclaved concrete blocks, it is found in actual use that when cutting the hand-held holes, the cut waste will splash everywhere and easily enter the transmission system of the cutting mechanism, thereby causing transmission vibration and rotation blockage, resulting in unstable operation of the hand-held hole device.

[0046] The utility model is further described below in conjunction with specific embodiments.

[0047] Example 1

[0048] like Figure 1 As shown, a handheld hole-making device for concrete blanks in this embodiment includes a frame 1 and a groove-making mechanism 2 and a driving mechanism 3 arranged on the frame 1 .

[0049] Wherein, the frame 1 serves as the installation base of the entire device;

[0050] The planing mechanism 2 is used to cut hand-held holes in the concrete body;

[0051] The driving mechanism 3 is used to drive the groove cutting mechanism 2 to move in the vertical direction to achieve groove cutting operations at different positions.

[0052] Specifically, refer to Figure 1 , Figure 2 As shown, the frame 1 includes a mounting platform 11 , legs 12 for supporting the mounting platform 11 , and suspension beams 13 arranged at both ends of the mounting platform 11 .

[0053] Furthermore, there are four supporting legs 12 , and each supporting leg 12 is provided with a guide rod 14 that cooperates with the planing mechanism 2 , and a guide rail 15 that cooperates with the lifting mechanism 4 .

[0054] refer to Figure 3 As shown, the planing mechanism 2 is located below the mounting platform 11 , and includes a planing frame 21 and a support frame 22 .

[0055] There are two sets of support frames 22 arranged relatively to each other, which are respectively slidably arranged below the cross beams on both sides of the groove planing frame 21. The support frames 22 are provided with groove planing components, and the support frames 22 are connected with respective moving components 26 for driving the two sets of support frames 22 and the groove planing components thereon to move away from or towards each other.

[0056] The slotting assembly includes a rotating shaft 23, a slotting cutter group 24 and a first driving source 25. The rotating shaft 23 is rotated on the support frame 22 through a bearing, and a plurality of slotting cutter groups 24 are arranged along the axial direction of the rotating shaft 23.

[0057] The first driving source 25 is located at the end of the support frame 22 and connected to the rotating shaft 23. Preferably, the first driving source 25 is a reduction motor, and the reduction motor is located outside the longitudinal beam of the planing frame 21.

[0058] That is, the cross beams and longitudinal beams of the slotting frame 21 together enclose a cutting area, and the slotting and cutting operation of the slotting assembly is mainly located in the cutting area, and the splashing of waste materials and the dust generated in this space are also the most serious. The first driving source 25 is arranged outside the cutting area, which can effectively reduce the interference of waste splashing on the transmission system and ensure its operation stability.

[0059] like Figure 4 As shown, the moving assembly 26 includes a second driving source 261 disposed outside the crossbeam of the slotting frame 21 , and an output end of the second driving source 261 is connected to the outer side wall of the support frame 22 .

[0060] Preferably, the second driving source 261 is a cylinder.

[0061] In order to ensure the stability of the movement of the support frame 22 , each support frame 22 is equipped with two groups of moving components 26 , and a synchronization component is provided between the support frame 22 and the groove planing frame 21 .

[0064] Specifically in this embodiment, the support frame 22 and the groove planing frame 21 are slidably matched through a guide rail slider, and each support frame 22 is provided with two sets of groove planing components.

[0065] In this embodiment, the driving mechanism 3 is arranged on the mounting platform 11, so that it is also far away from the cutting area to avoid interference from dust and waste during cutting. At the same time, it is beneficial to reduce the floor space and facilitate inspection and maintenance.

[0066] As an embodiment of the driving mechanism 3, refer to Figure 5 As shown, the driving mechanism 3 includes a third driving source 31 and a transmission box 32 arranged on both sides of the third driving source 31. Both sides of each transmission box 32 are connected to a transmission shaft 33, and the end of the transmission shaft 33 is provided with a main sprocket 34, and the main sprocket 34 is connected to a slave sprocket 35 on the leg 12 through a transmission chain.

[0067] Certainly, described planing groove framework 21 is provided with the suspension point for chain installation. Simultaneously, described planing groove framework 21 is provided with the guide sleeve 27 for guide rod 14 to pass through.

[0068] Preferably, the third driving source 31 is a reduction motor.

[0069] The present embodiment of the hand-held hole-making device for concrete blanks can effectively prevent the transmission system from being disturbed by waste splashes by moving the groove planing mechanism 2 and the transmission system of the driving mechanism 3 away from the cutting area, which is conducive to ensuring the stability of the transmission. At the same time, the synchronization of the gear and the rack is used to ensure the positioning accuracy, so as to avoid the use of high-precision equipment such as servo motors.

[0070] In addition, compared with the traditional design, the driving mechanism 3 only needs one reduction motor, which utilizes the chain tradition to transmit power to the four chain installation points of the grooving mechanism 2 through the "one-to-four" method, thereby reducing the number of electrical equipment, improving energy efficiency and reducing costs.

[0071] Example 2

[0072] The hand-held hole-making device for concrete blanks of this embodiment, based on the above embodiment, further comprises a lifting mechanism 4 for driving the bottom plate carrying the concrete blank to move up and down.

[0073] Specifically, refer to Figure 5 , Figure 6 As shown, the lifting mechanism 4 includes a lifting frame 41 and a fourth driving source 44 for driving the lifting frame 41 to move up and down.

[0074] The fourth driving source 44 is disposed on the suspension beam 13, and the fourth driving source 44 is preferably an oil cylinder or a gas cylinder.

[0075] The bottom of the lifting frame 41 is connected with a column 42, and a lifting block 43 is provided on the column 42. The lifting block 43 is provided with an air nozzle 49, which can perform dust cleaning operation on the cutting and conveying vehicle.

[0076] In this embodiment, the stability of the lifting mechanism 4 during movement is ensured.

[0077] The lifting frame 41 is provided with a second synchronization shaft 45 , and both ends of the second synchronization shaft 45 are provided with second synchronization gears 46 meshing with second synchronization racks 47 on the frame 1 .

[0078] At the same time, the column 42 is provided with a slider 48 that cooperates with the guide rail 15 on the leg 12 .

[0079] The working principle of the hand-held hole-opening device for concrete blanks in this embodiment is as follows:

[0080] When the transport vehicle carrying the concrete body enters the designated position under the frame 1, the hydraulic system in the lifting mechanism 4 begins to contract to lift the bottom plate and the concrete body thereon; if a double-cutting transport vehicle design is adopted, the vehicle change operation can be performed at this time.

[0081] The lifting and rotating grooving of the bottom plate can be carried out simultaneously. When the bottom plate is lifted, the reduction motors on both sides of the grooving mechanism 2 are started to rotate the grooving tool group 24, and the four hydraulic cylinders begin to extend and retract to cut out arc grooves; at the same time, driven by the driving mechanism 3, the grooving mechanism 2 is lifted, and by controlling the hydraulic pressure and the frequency of the reduction motor, the grooving can be controlled at different positions.

[0082] After cutting is completed, the hydraulic cylinder of the planing mechanism 2 always remains in a retracted state, and at the same time the hydraulic system in the jacking mechanism 4 begins to extend to put the bottom plate back onto the cutting conveyor vehicle, and thus a working cycle is completed.

[0083] The present invention provides a hand-held hole-opening device for concrete bodies, which is coupled with the hydraulic cylinder jacking through the coordination of gear racks, thereby achieving a buffering function and ensuring synchronization; the gear rack positioning has high accuracy and can reduce the workload of manual adjustment of mechanical positioning.

[0084] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
