Description

Technical Field

[0001] The invention relates to the technical field of concrete prefabricated part production, in particular to a concrete prefabricated frame supported by concrete pipe piles. Background Art

[0002] Concrete precast frame, also known as precast concrete frame structural system, is a structural system composed of precast concrete components assembled by reliable connection methods. This structural system has a wide range of applications and significant advantages in the field of modern construction.

[0003] Precast concrete frame cutting equipment is a commonly used mechanical equipment in the construction industry, mainly used to cut hard materials such as precast concrete frames. This type of equipment plays an important role in precast component production, building renovation, bridge maintenance and other fields.

[0004] At present, when using the precast concrete frame cutting equipment on the market, since grooves need to be cut on both sides of the precast concrete frame, the user is required to take the cutting tool and move it in different directions for cutting, which may cause deviations in the position and size of the grooves. At the same time, due to its own structural limitations, the existing precast concrete frame cutting equipment is unable to perform the functions of synchronous groove cutting on both sides and fixed-point discharge and synchronous resetting of the frame. Therefore, a device is needed to improve the above-mentioned problem. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides a prefabricated concrete frame supported by concrete pipe piles.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a concrete prefabricated frame supported by concrete pipe piles, including a support mechanism, a concrete prefabricated frame is placed on the top of the support mechanism, a guide device is symmetrically fixedly installed at the top front end of the support mechanism, the guide device includes a first hydraulic cylinder, a support top frame, a support shaft and a one-way push plate, the support top frame is fixedly installed at the rear end of the first hydraulic cylinder, the support shaft is fixedly installed at the bottom of the side end of the support top frame away from the first hydraulic cylinder, the top of the one-way push plate is rotatably installed on the outer ring of the support shaft, the support mechanism includes a facing component and a transmission component, the facing component is fixedly installed on both sides of the bottom of the transmission component, the facing component includes a displacement device and a transmission device, the displacement device is slidably plugged into the top of the transmission device, the displacement device includes a first gear, a winding wheel and a connecting rope, the winding wheel is fixedly installed at the bottom center of the first gear, the connecting rope is fixedly installed on the outer ring of the winding wheel, the end of the connecting rope away from the winding wheel is fixedly installed with a displacement vertical frame, and the displacement vertical frame is fixedly installed with two first cutting machines at the top of the side end close to the first gear.

[0007] Specifically, the transmission device includes a driving motor, a connecting base rod, a second gear and a third gear, the third gear is fixedly mounted on the top of the second gear, the second gear is fixedly mounted on the top center of the driving motor, the driving motor is symmetrically fixedly mounted on the top of the connecting base rod close to the second gear, the end of the connecting base rod away from the driving motor is fixedly mounted with a supporting base frame, and the supporting base frame is fixedly mounted with two first springs on the top of the side end close to the second gear; When the second gear drives the third gear to rotate until it meshes with the rack, the rack can be driven to move toward an end away from the special-shaped air cylinder.

[0008] Specifically, the transmission component includes a synchronization device and a conveying device, and the synchronization device is fixedly installed on both sides of the conveying device.

[0009] Specifically, the synchronization device includes a synchronization device, a first guide round rod, a second spring and a supporting base plate, the first guide round rod is slidably inserted in the interior of the extension base plate, the supporting base plate is fixedly installed at the bottom end of the first guide round rod, the second spring is fixedly installed between the extension base plate and the supporting base plate, and the second spring is located on the outer ring of the first guide round rod, a second cutting machine is fixedly installed at the bottom center of the supporting base plate, a second piston rod is symmetrically fixedly installed at the bottom end of the supporting base plate away from the second cutting machine, and the outer ring of the second piston rod is slidably sleeved with a special-shaped gas cylinder, the bottom end of the special-shaped gas cylinder is slidably inserted with the first piston rod, and the end of the first piston rod away from the special-shaped gas cylinder is fixedly installed with a rack; When the rack drives the first piston rod to move toward the end away from the special-shaped gas cylinder, the second piston rod and the second cutting machine can be driven to move downward at the same time.

[0010] Beneficial effects of the present invention: First, when the first hydraulic cylinder is started, the one-way push plate can be driven to squeeze the precast concrete frame and move it toward the rear end. The front end of the one-way push plate is fitted with the supporting top frame to prevent the one-way push plate from rotating toward the front end, so that the one-way push plate can stably push the precast concrete frame toward the rear end. At the same time, when the precast concrete frame slides along the inside of the guide conveyor frame, it can pass through the bottom end of the one-way push plate. At this time, the one-way push plate will rotate toward the rear end, thereby allowing the precast concrete frame to pass smoothly through the bottom end of the one-way push plate, thereby completing the discharge of the precast concrete frame. In addition, through the setting of the first spring and the second spring, the second cutting machine and the first cutting machine can be reset in time after the work is completed, thereby completing the reset work of the second cutting machine and the first cutting machine.

[0011] Second, when the present invention is started by the driving motor, the second gear can be driven to rotate, so that the second gear can intermittently drive the first gear to rotate, so that the connecting rope can pull the displacement frame closer to the guide conveyor frame until the first cutting machine cuts the precast concrete frame, and when the displacement frame is reset, the third gear will contact the rack, so that the first piston rod can move toward the end away from the special-shaped air cylinder, causing the second cutting machine to move downward to contact the top of the precast concrete frame, thereby completing the work of synchronously grooving the precast concrete frame.

[0021] like Fig. 9 The conveying device 24 includes a guide conveying frame 34, a base 36 and a second guide round rod 35. The second guide round rod 35 is symmetrically fixedly installed at the bottom ends of both sides of the base 36. The guide conveying frame 34 is fixedly installed at the top of the base 36.

Photoelectric sensors 38 are symmetrically fixedly installed on the top of the side ends of the side end frames 37 away from the guide conveying frame 34. Square grooves are opened through the centers of both sides of the guide conveying frame 34, so that the first cutting machine 12 can be easily contacted with the concrete prefabricated frame 3. When the precast concrete frame 3 slides to the rear end to the limit position inside the guide conveyor frame 34 , the precast concrete frame 3 can be guided out along the slope of the rear end surface of the guide conveyor frame 34 .

[0022] One end of the first hydraulic cylinder 4 away from the supporting top frame 5 is fixedly mounted on the top front end of the guide conveyor frame 34, the first gear 13 is symmetrically rotatably mounted on both sides of the bottom of the base 36, the special-shaped air cylinder 30 is symmetrically fixedly mounted on the outer top of the guide conveyor frame 34, the end of the extended base plate 33 away from the first guide round rod 25 is fixedly connected to the side end top of the side end frame 37 away from the photoelectric sensor 38, the end of the connecting base rod 22 away from the supporting bottom frame 21 is connected to the bottom of the base 36, the bottom rear end of the supporting top frame 5 is in contact with the front end surface of the one-way push plate 7, the first gear 13 is meshed with the second gear 18, the third gear 19 is horizontally aligned with the rack 28, the tooth distribution angle of the second gear 18 is 270°, the tooth distribution angle of the third gear 19 is 60°, and the top of the connecting base rod 22 is symmetrically opened. A card slot is provided, and a card key is symmetrically fixedly installed at the bottom end of the displacement vertical frame 16. The end of the first spring 20 away from the supporting base frame 21 is connected to the side end of the displacement vertical frame 16 away from the first cutting machine 12. The interior of the special-shaped air cylinder 30 is arranged in a hollow state, and a closed cavity is formed between the special-shaped air cylinder 30, the second piston rod 31 and the first piston rod 29. The end of the supporting base plate 27 away from the second spring 26 is vertically aligned with the photoelectric sensor 38. The rack 28 is slidably sleeved on the outer ring of the second guide round rod 35. The rear end bottom of the guide conveyor frame 34 is inclined at 45°. Another photoelectric sensor 38 is fixedly installed at the rear end bottom of the guide conveyor frame 34, and the top surface of the photoelectric sensor 38 is flush with the inner bottom end of the guide conveyor frame 34. The photoelectric sensor 38 is electrically connected to the first hydraulic cylinder 4.

[0023] The working principle of the embodiment 1 is as follows: when in use, the precast concrete frame 3 can be hoisted and placed inside the guide conveyor frame 34 by operating an external lifting device, and the two ends of the precast concrete frame 3 are fitted with the inner wall of the guide conveyor frame 34, so that the precast concrete frame 3 can be pushed to move in a straight line when displaced. When the precast concrete frame 3 is moved to a position where the first cutter 12 and the second cutter 32 are aligned, the first cutter 12 and the second cutter 32 can be started at the same time, and then the driving motor 17 is turned on to drive the second gear 18 and the third gear 19 to rotate at the same time. When the second gear 18 rotates, it can drive the first gear 13 to rotate at the same time, so that the first gear 13 can drive the winding wheel 14 to rotate, so that the winding wheel 14 can be connected to the first gear 13. The rope 15 pulls the displacement frame 16 to move toward one end close to the guide conveying frame 34, and the key at the bottom end of the displacement frame 16 moves in the groove inside the top end of the connecting base rod 22, so that the displacement frame 16 can be supported to move in a straight line. When the second gear 18 rotates 270°, the displacement frame 16 can be pulled to move to the limit position, so that the first cutting machine 12 can be displaced on the side end of the precast concrete frame 3, so that the side end of the precast concrete frame 3 can be cut. Subsequently, when the second gear 18 rotates 270°, the second gear 18 will lose engagement with the first gear 13. At this time, the first spring 20 will pull the displacement frame 16 to quickly reset, so that the first cutting machine 12 can be reset, and the second gear 18 will also drive the third gear 19 to rotate. The third gear 19 is moved to mesh with the rack 28. When the third gear 19 continues to rotate, the rack 28 can be driven to move toward one end away from the first piston rod 29, so that the first piston rod 29 can be pulled outward from the inside of the special-shaped gas cylinder 30, causing the second piston rod 31 to move toward the inside of the special-shaped gas cylinder 30, and the supporting base plate 27 will move downward, so that the second cutter 32 can cut the precast concrete frame 3. Subsequently, when the third gear 19 rotates and passes through the rack 28, the rack 28 will lose its meshing force, and the elasticity of the second spring 26 will drive the supporting base plate 27 to reset upward, so that the second cutter 32 can be out of contact with the precast concrete frame 3. The two first cutters 12 are in contact with the side ends of the precast concrete frame 3, and the second cutter 32 is in contact with the precast concrete frame 3. The top side end of the frame 3 contacts, so that when the first cutting machine 12 and the second cutting machine 32 are moved to the limit positions respectively, a groove can be opened on the side end of the concrete precast frame 3 to complete the grooving work of the side end of the concrete precast frame 3. Subsequently, when the supporting base plate 27 is reset upward, it can contact the photoelectric sensor 38, so that the first hydraulic cylinder 4 can be started. When the first hydraulic cylinder 4 is started, the supporting top frame 5 can be driven to the rear end position. Subsequently, when the one-way push plate 7 contacts the front end of the concrete precast frame 3, the front end of the one-way push plate 7 contacts the bottom rear end of the supporting top frame 5, so that the supporting top frame 5 can prevent the one-way push plate 7 from rotating toward the front end, so that the piston rod inside the first hydraulic cylinder 4 can drive the supporting top frame 5 and the one-way push plate 7 to move toward the rear end.Thereby, the one-way push plate 7 can push the precast concrete frame 3 to the rear end position. When the one-way push plate 7 moves to the limit position, the precast concrete frame 3 can move to the slope area at the rear end of the guide conveyor frame 34. At this time, the precast concrete frame 3 will slide downward along the inside of the guide conveyor frame 34 and move out. When the precast concrete frame 3 passes the photoelectric sensor 38 on the slope of the guide conveyor frame 34, the first hydraulic cylinder 4 can be triggered to reset, so that the supporting top frame 5 and the one-way push plate 7 can be reset, so that the one-way push plate 7 can push the precast concrete frame 3 again to complete the work. When the device is in use, when the displacement vertical frame 16 is reset, the connecting rope 15 can be pulled to drive the winding wheel 14 and the first gear 13 to rotate and reset quickly, so as to facilitate The second gear 18 drives the first gear 13 to rotate again. At the same time, when the concrete precast frame 3 passes the bottom end of the one-way push plate 7, it can drive the one-way push plate 7 to rotate toward the side end away from the first hydraulic cylinder 4, so that the concrete precast frame 3 passes through the bottom end of the one-way push plate 7. The rack 28 is slidably sleeved on the second guide round rod 35, so that the rack 28 can be ensured to move in a straight line to avoid the rack 28 from rotating crookedly. When the first cutter 12 moves to the extreme position close to the end of the guide conveyor frame 34, the incision can be vertically aligned with the second cutter 32, so that when the second cutter 32 moves downward, it can pass through the incision generated by the first cutter 12, and a complete cut groove can be formed on the concrete precast frame 3. Example 2

[0024] On the basis of Example 1, Fig.10 As shown, the guide conveyor frame 34 also includes a push frame 39, an extended side arm 40 and a second hydraulic cylinder 41. The extended side arm 40 is fixedly installed at the center of both sides of the guide conveyor frame 34, the second hydraulic cylinder 41 is fixedly installed inside the extended side arm 40, the push frame 39 is fixedly installed at one end of the second hydraulic cylinder 41 close to the guide conveyor frame 34, and a through hole is opened at the center of the bottom end of the guide conveyor frame 34.

[0025] When implementing this embodiment, after grooves are opened on both sides of the top of the precast concrete frame 3, the cut waste can fall on the bracket at the bottom end of the interior of the precast concrete frame 3. By making the bottom end of the push frame 39 flush with the bottom end of the bracket at the bottom end of the interior of the precast concrete frame 3, the second hydraulic cylinder 41 can be started to drive the push frame 39 to move toward the inside of the guide conveyor frame 34, so that the push frame 39 can push the waste at the bottom end of the interior of the precast concrete frame 3 to move out of the interior of the precast concrete frame 3 and fall. A through hole is opened in the inner center of the guide conveyor frame 34, so that the waste can fall into the through hole, thereby completing the waste removal work.
