The following detailed description is made with reference to the accompanying drawings.

Example 1

The utility model relates to a lining cutting device of ecological lining cutting river course, it includes can unite the pot hole wall in the river course groove that the excavation is good and build river course forming component 1 that is used for the lining cutting space of lining cutting river course wall and can treat the concrete that gets into the lining cutting space and carry out secondary treatment with the homogeneous mixing that strengthens the concrete material in the microcosmic and improve its cohesiveness's preliminary treatment component 2.

According to a specific embodiment shown in fig. 1, the pre-processing assembly 2 can perform secondary performance strengthening treatment combining forced stirring and vibration strengthening on precast concrete which is subjected to preliminary stirring and mixing or is stirred in advance from a large-scale manufacturing device, so that the mixing uniformity of concrete materials is effectively improved in a microscopic angle, the solid, liquid and gas three-phase microscopic and microscopic uniformity of the concrete is good, the connection and hole distribution state between a cement stone and an aggregate interface is improved, the strength of a cast concrete layer is improved, and the durability is better. The pretreatment assembly 2 comprises a treatment cavity 3 which can contain precast concrete and can be selectively communicated with a lining space constructed by the river channel forming assembly 1, and a vibrating stirring assembly 4 which can improve the performance of the concrete in different movement modes in the treatment cavity 3 and directionally drive the concrete after secondary treatment to quickly fill the lining space constructed by the river channel forming assembly 1. The vibration stirring component 4 can perform secondary treatment of performance optimization on the concrete contained in the treatment cavity 3 in a mode of combining forced stirring and vibration strengthening, so that the inner pores of the concrete move towards the reduction direction, the number of small pores is increased while the large pores are reduced, and the capillary pores and gel pores are increased, so that the durability, frost resistance and impermeability of the concrete are greatly improved in a mode of improving the pore grading and pore distribution of the concrete.

As shown in fig. 1 and 5, the vibratory stirring assembly 4 includes a stirring shaft 41 and a stirring member 42. One end portion of the stirring member 42 in the longitudinal direction is fixedly connected to the stirring shaft 41. The stirring members 42 are arranged on the surface of the stirring shaft 41 at intervals along the circumferential direction of the stirring shaft 41 in a manner of rotating around the stirring shaft 41, and a plurality of groups of stirring members 42 arranged at intervals are arranged on the same stirring shaft 41 along the axial direction of the same stirring shaft 41, so that the stirring members 42 positioned at different positions in the axial direction of the stirring shaft 41 can synchronously stir and vibrate the concrete at the upper, middle and lower layers in the treatment cavity 3. Specifically, the stirring member 42 selectively vibrates the concrete in the treatment chamber 3 according to the rotation direction thereof or drives the concrete to be discharged from the opening at the bottom of the treatment chamber 3 and directionally conveyed into the lining space. Preferably, the stirring element 42 is arranged outside the stirring shaft 41 with its plate plane at a set inclined angle to the axis of the stirring shaft 41. The included angle of inclination is set to 15-30 degrees depending on the manner in which the concrete is selectively driven to roll up in the treatment chamber 3 or to be driven in a downward manner towards the opening of the treatment chamber 3. By connecting stirrer 42 to stirrer shaft 42 in an inclined manner, stirrer 42 can be rotated with stirrer shaft 42 to scoop up concrete in treatment chamber 3 or to press down concrete in treatment chamber 3.

As shown in fig. 3, for example, when stirring member 42 is attached to the surface of the shaft of mixing shaft 41 such that the width direction of the plate body thereof is at an angle of 30 degrees to the axis of mixing shaft 41, stirring member 42 rotates clockwise following mixing shaft 41, and the lower end of stirring member 42 serves as the movement front end to scoop up concrete and cause the scooped concrete to move relatively to rotating stirring member 42 in a gradually rising manner along the inclined plate surface thereof, thereby realizing tumble mixing of concrete under the rotation of stirring member 42. Preferably, the stirring member 42 is inclined at the high end of the plate body with respect to the rotation direction when performing the rotational movement. The concrete material, which is scooped up by the stirring member 42 and ascends by a certain height, drops after being separated from the high end of the plate body of the stirring member 42 to fill the gap space formed below the plate body of the stirring member 42, which is disposed obliquely. The rotation of the stirring member 42 drives the concrete to perform a lifting motion in height, so that the concrete performs a relative motion and a cooperative motion between materials in the lifting process, the pores inside the concrete are reduced, and pores and gel pores are increased while large pores are reduced because gas is not completely discharged out of the concrete, thereby improving the pore gradation and pore distribution of the concrete. When stirrer 42 is driven by stirrer shaft 41 to rotate counterclockwise, the high end of stirrer 42 serves as the front end of movement, and as stirrer 42 rotates, the plate body of stirrer 42 inclined with respect to the axis of stirrer shaft 41 can press the concrete in a manner of driving the concrete to move toward the bottom of treatment chamber 3, so that when treatment chamber 3 is communicated with the lining space, counterclockwise rotation of stirrer 42 can press the concrete to be discharged from treatment chamber 3. Preferably, the size of stirring piece 42 is set up according to the cavity volume of treatment chamber 3, and stirring piece 42 is rotatory and can also clear up and discharge the abundant adhering concrete of treatment chamber 3 inner chamber wall when driving the concrete motion to guarantee that the volume of holding and the single effective handling capacity of treatment chamber 3 inner chamber remain unchanged.

The outer rotating shaft 412 is sleeved on the inner vibrating shaft 411 and can rotate relative to the inner vibrating shaft 411, and the inner vibrating shaft 411 can drive the outer rotating shaft 412 to reciprocate in the axial direction together with the outer rotating shaft 412, so that the stirring part 42 arranged on the stirring shaft 41 can transmit vibration to the concrete in contact with the two surfaces of the plate body in a way of fluctuating up and down in the concrete along with the reciprocating motion of the inner vibrating shaft 411, and the concrete body can be flapped by the stirring part 42 in the axial direction to transmit vibration force to the mixed material. As shown in fig. 4, the stirring members 42 are disposed on the shaft wall of the rotating outer shaft 412, and the stirring members 42 can rotate following the rotation of the rotating outer shaft 412, thereby completing the stirring in such a manner that the concrete mixture is cut and ascends along the obliquely disposed plate body thereof with the concrete. Preferably, the stirring member 42 can move up and down along with the reciprocating motion of the vibrating inner shaft 411 while rotating and stirring, and transmit the vibration force in a mode of slapping the concrete mixture, so that the stirring member 42 can forcibly stir the concrete in the treatment cavity 3 while rotating, and can also vibrate and strengthen the mixing uniformity of the concrete mixture in a mode of transmitting the vibration force to the concrete, thereby increasing capillary pores and gel pores while reducing a large number of large-volume pores existing in the concrete, and further improving the durability and strength of the concrete.

As shown in fig. 2, the stirring member 42 includes a double-curved arc plate 421 bent into a double-curved surface, an inflation protrusion 422 uniformly arranged on the double-curved arc plate 421, and a protection sleeve 423 sleeved on the double-curved arc plate 421 for protecting the arc plate body and the inflation protrusion 422 and reducing the adhesion of concrete on the surface thereof.

Further preferably, the first direction is the width direction of the plate body, i.e. the section along the length direction of the hyperbolic arc plate 421 is just capable of forming an arc with double curvature. Under the condition that one end of the hyperbolic arc plate 421 in the length direction is connected with the stirring shaft 41, the circumferential tangent line of the hyperbolic arc plate 421 in the rotation process is coincident with or parallel to the width direction of the hyperbolic arc plate. The concrete that is shoveled by hyperbolic arc 421 can be followed the width of hyperbolic arc 421 and sent up and take place relative motion to hyperbolic arc 421 can drive its concrete slope that shovels and rise the time can also produce the vibration of fluctuation from top to bottom, thereby can promote the mixture between the concrete material better.

Preferably, the double curved arc 421 can scoop up the concrete at the same height as the lower end when rotating clockwise and force the concrete to move relatively and climb along the surface of the plate body. Under the interaction force generated by the rotation of the double-curved arc plate 421, the concrete can rise along the plate surface of the double-curved arc plate 421 and is forcibly stirred to eliminate the large-volume gap existing in the material. Preferably, while the concrete is forcibly stirred, the inner vibrating shaft 411 can drive the outer rotating shaft 412 to synchronously reciprocate and translate in the axial direction, so that the hyperbolic arc plate 421 can transmit vibration in a slapping manner to the concrete.

Preferably, the surface of the hyperbolic arc plate 421 is uniformly distributed with inflatable bulges capable of periodically changing volume. Specifically, the inflatable bumps 422 generate periodic volume changes according to the way that the hyperbolic arc plate 421 can drive the concrete to perform secondary treatment by the plate surface with the real-time change of the surface shape, so that the hyperbolic arc plate 421 can construct a dynamic uneven surface to reduce the adhesion of the concrete on the plate surface. The setting of aerifing protruding 422 makes the face of hyperbolic arc 421 be in the state that the surface area that lasts changes at the in-process of rotating the stirring concrete, can reduce the possibility of concrete adhesion on the face of plate effectively, aerify protruding 422 simultaneously can strengthen the intensity when taking place relative motion between concrete and hyperbolic arc 421, thereby make bulky material such as grit in the concrete mixture can roll better in cementitious material such as cement, pitch under the effect of aerifing protruding 422, stir, promote the bulky space that exists in the concrete to be extruded by the grit material that moves, fill. Preferably, the arc plate body of the hyperbolic arc plate 421 can make the concrete driven and stirred by the arc plate body generate upward rolling motion on the plate body and simultaneously generate up-and-down motion along with the surface fluctuation of the plate body, so as to promote the hyperbolic arc plate 421 to stir the mass concrete materials glued together, and generate collision and extrusion among the materials and eliminate mass gaps in the up-and-down fluctuation process. Further preferably, the air-filled protrusion 422 with the constantly changing volume can also make the lifted concrete vibrate and stir by the stirring member 42 and simultaneously make the supporting force of the plate body on the lifted concrete change, so as to further eliminate the gap in the concrete by relaxation and extrusion of the gap.

Example 3

This embodiment is a further improvement of embodiment 1, and repeated contents are not described again.

As shown in fig. 6, the tapping assembly 5 mounted on the lining limit assembly 1 includes a vibration cylinder 51, a first movable cylinder 52 and a second movable cylinder 53. The vibration cylinder 51 divides the inner chamber into two sub-chambers by a vibration unit 511 disposed in the inner chamber, wherein the surfaces of the vibration unit 511 facing the two sub-chambers are respectively provided with a vibration piston 512. The two sub-chambers of the vibration cylinder 51 are also communicated with the first movable cylinder 52 and the second movable cylinder 53, respectively.

Preferably, a first piston 521 capable of directionally moving along the inside of the first movable oil cylinder 52 is arranged in the first movable oil cylinder, and a first piston ring 523 and a first sealing ring 322 for ensuring effective movement of the first piston 521 are arranged on the first piston 521. The reciprocating movement of the first piston 521 in the first movable cylinder 52 causes the volume of the hydraulic oil in the first movable cylinder 52 to follow. The first piston 521 is also connected by a piston pin to a first link 524. An end of the first link 524 remote from the first piston 521 is connected to the flywheel 54 by a flywheel pin, so that the first piston 521 can reciprocate and translate in the first movable cylinder 52 following the rotation of the flywheel 54. Preferably, a second piston 531 capable of directionally moving along the inside of the second movable oil cylinder 53 is arranged in the second movable oil cylinder 53, and a second piston ring 533 and a second sealing ring 532 for ensuring effective movement of the second piston 531 are arranged on the second piston 531. The second piston 531 is also connected to a second connecting rod 534 by a piston pin. The end of the second connecting rod 534 remote from the second piston 531 is connected to the flywheel 54 by a flywheel pin, so that the second piston 531 can reciprocate and translate in the second traveling cylinder 53 following the rotation of the flywheel 54. The axial directions of the first movable cylinder 52 and the second movable cylinder 53 are coincident with each other, and the flywheel 54 is disposed between the first movable cylinder 52 and the second movable cylinder 53, so that the flywheel 54 connects the first link 524 and the second link 534 through the same flywheel pin. One end of the first movable oil cylinder 52, which is far away from the second movable oil cylinder 53, is communicated with one sub-chamber of the vibration oil cylinder 51 through an oil pipe, and one end of the second movable oil cylinder 53, which is far away from the first movable oil cylinder 52, is also communicated with the other sub-chamber of the vibration oil cylinder 51 through an oil pipe. When the first movable oil cylinder 52 and the second movable oil cylinder 53 are respectively communicated with different sub-chambers of the vibration oil cylinder 51, the vibration piston 512 limiting the chamber volumes of the different sub-chambers of the vibration oil cylinder 51 is enabled to translate by changing the amount of hydraulic oil in the first movable oil cylinder 52 and/or the second movable oil cylinder 53, so that the two sub-chambers of the vibration oil cylinder 51 realize the change of the chamber volumes according to the reciprocating translation of the vibration piston 512, and the vibration oil cylinder 51 is driven to transmit vibration force along with the interaction force of the hydraulic oil and the vibration piston 512 in the change process.

Preferably, the flywheel 54 is further connected to a driving motor capable of driving the flywheel to rotate. When the device is used, the driving motor drives the flywheel 54 to rotate, and the flywheel 54 drives the first connecting rod 524 and the second connecting rod 534 to reciprocate between the first movable oil cylinder 52 and the second movable oil cylinder 53, so as to drive the first piston 521 and the second piston 531 to respectively perform reciprocating translation in the same direction in the inner chambers of the first movable oil cylinder 52 and the second movable oil cylinder 53. Specifically, when the driving motor drives the flywheel 54 to rotate, the flywheel pin on the flywheel 54 moves in a direction close to the second movable cylinder 53, and the flywheel 54 drives the first connecting rod 524 and the second connecting rod 534 to move in the first direction, so that the first connecting rod 524 and the second connecting rod 534 pull or push the first piston 521 and the second piston 531 to translate in the first direction. Along with the translation of the first piston 521 and the second piston 531 in the first direction, the hydraulic oil in the sub-chamber where the vibration oil cylinder 51 is communicated with the first movable oil cylinder 52 flows into the first movable oil cylinder 52, and simultaneously the hydraulic oil in the second movable oil cylinder 53 synchronously flows into the sub-chamber where the vibration oil cylinder 51 is communicated with the second movable oil cylinder 53, so that the hydraulic oil in the two sub-chambers in the vibration oil cylinder 51 simultaneously changes, and the vibration piston 512 is pushed to translate in the inner chamber of the vibration oil cylinder 51. After the flywheel pin moves to the position closest to the second movable cylinder 53, the flywheel pin moves along with the flywheel 54 to gradually get away from the second movable cylinder 53 and gradually get close to the first movable cylinder 52 along with the rotation of the flywheel 54. The first piston 521 moves in the second direction, and the movement of the first piston 521 reduces the accommodating space of the hydraulic oil in the first movable oil cylinder 52, so that the hydraulic oil in the first movable oil cylinder 52 is discharged from the first movable oil cylinder 52 into the sub-chamber of the vibration oil cylinder 51. The second piston 531 also moves in the second direction following the second link 534, so that the second piston 531 moves in the second direction, and the space in the second movable cylinder 53, in which the hydraulic oil can be accommodated, increases, so that the hydraulic oil in the sub-chamber of the vibration cylinder 51 connected to the second movable cylinder 53 flows into the second movable cylinder 53. Preferably, the first direction is a direction in which the first movable cylinder 52 points to the second movable cylinder 53, and the second direction is a direction in which the second movable cylinder 53 points to the first movable cylinder 52, wherein the first direction and the second direction are exactly opposite to each other. In actual operation, the flywheel 54 transmits the rotating force thereof in a transmission mode to enable the vibration piston 512 to drive the vibration oil cylinder 51, so that the vibration force transmission of the vibration oil cylinder 51 is completed in one activity period of the flywheel 54, the device has a simple structure and high transmission efficiency, the service life of the tap assembly 5 is greatly prolonged, and the failure rate of the tap assembly 5 is reduced.
