Description

Technical Field

[0001] The present invention relates to a canal slipform machine, belonging to the technical field of slipform machines. Background Art

[0002] A water canal is a waterway for water flow in a water conservancy project, mainly used for guiding water flow. Usually, a water canal is directly excavated on the ground. However, since the inner wall of such a water canal is made of soil, it needs to be frequently cleaned. In recent years, a new type of water canal with a concrete-hardened inner wall is gradually being promoted. In actual construction, the slope of the water canal is a ramp. When performing concrete construction, first, concrete needs to be poured on the ramp, and then the poured concrete material needs to be spread, cloth-fed, and scraped. Since the working surface is a ramp, it is not suitable to use a paver for flat ground construction. The traditional construction method relies more on manual construction. After pouring concrete on the ramp, manual labor is involved, which not only has low construction efficiency but also has the disadvantage of high labor intensity.

[0003] For a concrete surface with a certain cross-sectional shape, a slipform machine can usually be used, but an ordinary slipform machine is only suitable for construction on a relatively flat road surface. The slope of a river canal is inclined, and when laying concrete material, it is not possible to well ensure that the concrete material is evenly spread on the inclined slope.

[0004] In the prior art, there is a water canal lining machine that can perform integrated concrete paving construction for a water canal, but the cross-section and span of the water canal that such a water canal lining machine can construct are small. Summary of the Invention

[0005] The purpose of the present invention is to provide a new type of river canal slipform machine to solve the above problems.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: A river canal slipform machine includes a main truss with traveling mechanisms arranged at both ends, a feeding mechanism installed below the main truss, a buffer type blanking mechanism installed on one side of the main truss, and a control platform arranged at the upper end of the main truss; the feeding mechanism is a belt conveyor, and a number of baffle plates are arranged in the running direction of the belt of the belt conveyor for allowing the concrete material to enter the buffer type blanking mechanism; the buffer type blanking mechanism is provided with blanking channels extending along the slopes on both sides of the river canal and the bottom of the river canal, and a number of buffer blocking plates are arranged at intervals in the blanking channels, and vibrating rods are correspondingly arranged below the buffer blocking plates; an electric control box and a hydraulic pump station are arranged on the control platform.

[0007] A further improvement of the technical solution of the present invention is that a buffer type blanking mechanism is arranged on one side of the main truss, and a stepped working platform is fixedly arranged on the opposite side.

[0008] A further improvement of the technical solution of the present invention is that three sets of baffle plates are provided.

[0009] A further improvement of the technical solution of the present invention is that the three sets of baffle plates are respectively located at the two end positions and the middle position of the belt conveyor, and the distances between the lower end faces of the three sets of baffle plates and the belt conveyor are different.

[0010] A further improvement of the technical solution of the present invention is that one end of the belt conveyor is the feeding end, and the distance between the lower end face of the baffle plate at the end opposite to the feeding end and the belt conveyor is 0 to 1 mm; the distances between the lower end faces of the baffle plates at the middle position and the feeding end position and the belt conveyor are adjustable.

[0011] A further improvement of the technical solution of the present invention is that the upper ends of the baffle plates at the middle position and the feeding end position are connected to a hydraulic baffle height adjusting rod; a cross frame for installing the baffle height adjusting rod is fixedly arranged across the belt conveyor, and the baffle height adjusting rod is fixedly connected to the cross frame.

[0012] A further improvement of the technical solution of the present invention is that a paving frame with the same shape as the cross-section of the river channel and used for paving the concrete material is arranged below the corresponding belt conveyor; one side of the paving frame facing the river channel slope and the bottom surface is a flat plate.

[0013] A further improvement of the technical solution of the present invention is that the buffer feeding mechanism and the stepped workbench are respectively fixedly connected to the two side surfaces of the paving frame.

[0014] A further improvement of the technical solution of the present invention is that a blanking cylinder is provided corresponding to the baffle plate at the middle position; the upper end of the blanking cylinder corresponds to the discharge port of the baffle.

[0015] A further improvement of the technical solution of the present invention is that two relatively inclined baffle plates are arranged at the lower end of the blanking cylinder, and the upper ends of the two baffle plates divide the blanking port of the blanking cylinder into three blanking channels.

[0016] Due to the adoption of the above technical solution, the technical effects obtained by the present invention are as follows: The present invention is provided with a feeding mechanism and a buffer feeding mechanism, and the two cooperate with each other to be able to reasonably distribute the concrete material, so that the concrete material can be paved more evenly on the two side slopes and the bottom surface of the river channel, ensuring that the thickness of the concrete paving is relatively uniform and guaranteeing the construction quality.

[0017] The present invention sets three baffle plates for enabling concrete materials to enter a buffer type blanking mechanism along the running direction of the belt of a belt conveyor, so that the concrete materials on the belt conveyor can smoothly enter the buffer type blanking mechanism. The three baffle plates are respectively located at the two end positions and the middle position of the belt conveyor, and the distances between the lower end surfaces of the three baffle plates and the belt conveyor are different. The distances between the lower end surfaces of the baffle plate at the middle position and the baffle plate at the feeding end position and the belt conveyor are adjustable and can be adjusted according to the actual construction situation, so as to make the concrete materials as evenly distributed as possible.

[0018] The buffer type blanking mechanism set by the present invention enables the concrete materials to fall slowly and evenly from the upper ends of the slopes on both sides of the river channel. The buffer type blanking mechanism is provided with a blanking channel, and buffer blocking plates are arranged at intervals in the blanking channel. There is a certain distance interval between the lower ends of the buffer blocking plates and the lower end of the blanking channel, so as to ensure that the concrete materials can fall slowly, so that the concrete materials can be scattered at various positions of the river channel slope, ensuring uniform paving.

[0019] The present invention fixedly sets a cross frame across the belt conveyor at the position of the baffle plate, and a telescopic end baffle height adjusting rod is arranged for the baffle plate. The fixed end at the upper end of the baffle height adjusting rod is fixedly connected with the cross frame, and the telescopic end at the lower end is fixedly connected with the baffle plate. The baffle height adjusting rod drives the baffle plate to move up and down to realize the adjustment of the distance between the baffle plate and the belt conveyor. This structure can conveniently control the amount of concrete supplied by the belt conveyor at various positions. The baffle height adjusting rod is a hydraulic telescopic rod, which is convenient for adjustment and use in actual construction.

[0020] The present invention is a new type of mechanized river channel slip form machine, which can realize the integrated construction operation of concrete paving and scraping on the inner wall of a river channel with a large span, improve work efficiency, reduce work intensity, and also improve construction quality.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] The present invention is a canal slip form machine for paving and spreading concrete on the inner wall of a canal and performing finishing construction. The canal slip form machine can achieve the integrated construction of the inner wall of the canal.

[0027] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the canal slip form machine includes a main truss 1, a feeding mechanism for conveying concrete materials, and a cache type blanking mechanism for spreading the concrete materials on the canal slope and the canal bottom surface. Longitudinal traveling mechanisms are connected and arranged at both ends of the main truss 1, which can drive the whole machine to travel longitudinally. A control platform 2 is fixedly arranged at the upper end of the main truss 1, and an electric control box and a hydraulic pump station are arranged on the control platform 2 to provide electric power and hydraulic power respectively. The control part of the canal slip form machine is arranged on the control platform. The longitudinal traveling mechanism can be a wheeled traveling mechanism or a crawler type traveling mechanism.

[0028] This slip form machine is used for the concrete construction of canals. When feeding the materials, the feeding is carried out from the upper ends on both sides of the canal, so that the concrete materials gradually slide down from the lower ends on both sides of the canal to the canal bottom surface; in addition, usually, it is also necessary to directly supply the concrete materials to the canal bottom surface to ensure sufficient supply of concrete materials at the canal bottom surface, especially in the middle part. The feeding mechanism of this slip form machine is a belt conveyor 3, which conveys the concrete materials provided by the pump truck through the belt conveyor 3. At the same time, a cache type blanking mechanism is also configured. The concrete materials on the belt conveyor 3 are first conveyed to the cache type blanking mechanism, and then the cache type blanking mechanism spreads the concrete materials more evenly on the canal slope and the bottom surface.

[0029] In order to enable the concrete materials on the belt conveyor 3 to smoothly enter the cache type blanking mechanism, a number of baffle plates 4 for enabling the concrete materials to enter the cache type blanking mechanism are arranged in the running direction of the belt of the belt conveyor 3. Usually, three groups of baffle plates 4 are arranged, and the three groups of baffle plates 4 are respectively located at the two end positions and the middle position of the belt conveyor 3. The baffle plate 4 is inclined with respect to the running direction of the belt of the belt conveyor 3. When feeding the materials, the feeding is carried out from the upper ends on both sides of the canal, so that the concrete materials gradually slide down from the lower ends on both sides of the canal to the canal bottom surface, and the concrete materials are gradually dispersed during the sliding process; at the same time, it is also necessary to directly supply concrete to the bottom surface part of the canal. The three groups of baffle plates 4 are used to control the amount of concrete conveyed to the two ends and the middle position of the belt conveyor 3.

[0030] The belt conveyor 3 of this canal slip form machine is fixed on the main truss 1 through a bracket, and both ends of the belt conveyor are slightly longer, which is convenient for injecting concrete materials onto the belt conveyor. Usually, a concrete pipe is used to convey the concrete materials onto the belt conveyor.

[0031] The lower end surfaces of the three groups of baffle plates 4 are at different distances from the belt conveyor 3. One end of the belt conveyor 3 is set as the feeding end. The distance between the lower end surface of the baffle plate 4 at the other end opposite to the feeding end and the belt conveyor 3 is 0 - 1 mm. This end is far from the feeding end. After the concrete material is conveyed here, there is no remainder. The baffle plate 4 at this position does not need to move in height and is in a fixed state. The distances between the lower end surfaces of the baffle plates 4 at the middle position and the feeding end position and the belt conveyor 3 are adjustable and can be adjusted according to the actual construction situation to make the concrete material distributed as evenly as possible. The specific structure can be set as follows: A cross-frame 13 is fixedly arranged across the belt conveyor 3, and a baffle height adjustment rod 14 is set for the baffle plate 4. The baffle height adjustment rod 14 has a telescopic end, generally directly using a hydraulic telescopic rod, and the hydraulic telescopic rod is connected to the hydraulic system of the machine. The fixed end at the upper end of the baffle height adjustment rod 14 is fixedly connected to the cross-frame 13, and the telescopic end at the lower end is fixedly connected to the baffle plate 4. The baffle height adjustment rod 14 drives the baffle plate 4 to move up and down to realize the adjustment of the distance between the baffle plate 4 and the belt conveyor 3. The cross-frame 13 is fixedly connected to the main truss 1. Specifically as Figure 4 、 Figure 8 、 Figure 9 shown. Figure 4 The baffle height adjustment rod and the cross-frame of the baffle plate at the middle position are not drawn.

[0032] The present invention is provided with a buffer type blanking mechanism to make the concrete material fall from the upper ends of the slopes on both sides of the river channel more evenly and slowly. Specifically, the buffer type blanking mechanism is provided with a blanking channel 5, and a number of buffer baffle plates 6 are arranged at intervals in the blanking channel 5. The buffer baffle plates 6 are fixed in the blanking channel 5, and there is a certain distance interval between the lower ends of the buffer baffle plates 6 and the lower end of the blanking channel 5, so as to ensure that the concrete material does not slide down quickly but can fall slowly. The preferred setting method is that the distances between the lower ends of the buffer baffle plates 6 and the lower end of the blanking channel 5 decrease successively from top to bottom; that is to say, the distance between the lower end of the buffer baffle plate 6 near the upper end of the river channel slope and the lower end of the blanking channel 5 is large, and the distance between the lower end of the buffer baffle plate 6 near the bottom of the river channel and the lower end of the blanking channel 5 is small. A vibrating rod 7 is correspondingly arranged at the lower part of the buffer baffle plate 6, which can vibrate the concrete material and prevent the concrete material from piling up at the same time. The vibrating rod 7 is driven by a high-frequency vibrating motor to vibrate. The overall extension trend of the blanking channel 5 is along the slopes on both sides of the river channel and the bottom of the river channel, generally presenting an inverted trapezoid. Specifically as Figure 6 、 Figure 7 shown.

[0033] As Figure 2 、 Figure 4 、 Figure 5As shown in the figure, a caching type blanking mechanism is arranged on one side of the main truss 1, and a stepped working platform 8 is fixedly arranged on the opposite side. In the running direction of the canal slip form machine, the caching type blanking mechanism is arranged at the front end, and the stepped working platform 8 is arranged at the rear end.

[0034] Furthermore, in the present invention, a paving frame 9 with a shape consistent with the cross-section of the canal is arranged below the corresponding belt conveyor 3. The paving frame 9 plays a role in paving and leveling the concrete material. At the same time, the paving frame 9 is connected to the main truss 1, and the two together form the main frame part of the canal slip form machine. The side of the paving frame 9 facing the canal slope and the bottom surface is a flat plate. The caching blanking mechanism and the stepped working platform 8 are respectively fixedly connected to the two side surfaces of the paving frame 9. The paving frame 9 can perform scraping and paving on the concrete material, and the stepped working platform 8 is for workers to stand on. Workers stand on the stepped working platform 8 to manually level the uneven positions of the concrete surface. Specifically, as Figure 3 shown. The requirements for flatness and smoothness of the canal are lower than those of the road surface of a highway or a bridge. After the concrete surface is scraped and leveled by a paver, the requirements can basically be met. Workers only need to level the positions with relatively poor flatness and smoothness, and the labor intensity here is not high.

[0035] In order to ensure that the concrete falling from the middle position of the belt conveyor 3 can smoothly reach the lower part of the caching blanking mechanism, a blanking cylinder 10 is arranged on the side surface of the baffle 4 corresponding to the middle position. The discharging end of the baffle 4 at this position corresponds to the feeding port at the upper end of the blanking cylinder 10, and the concrete material is discharged through the blanking cylinder 10. Furthermore, two relatively inclined distributing plates 11 are arranged at the lower end of the blanking cylinder 10. The two distributing plates 11 arranged at this position are used to redistribute the concrete falling from the blanking cylinder 10. The upper ends of the distributing plates 11 are located at the blanking opening of the blanking cylinder 10, and can divide the blanking opening of the blanking cylinder 10 into three blanking channels, and the three blanking channels are respectively directed downward and to both sides. The specific structure is as Figure 5 shown.

[0036] The present invention can realize the mechanized concrete batching, paving and leveling of the inner wall of the canal, improve work efficiency and reduce work intensity. The present invention is particularly suitable for the concrete construction of the inner wall of large-span and large canals. The feeding mechanism and the caching type blanking mechanism of the present invention cooperate with each other to reasonably distribute the concrete material, ensuring that the paving thickness of the concrete on the canal slope and the canal bottom surface is relatively uniform.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention.
