Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and in particular relates to a road construction concrete pouring device. Background Art

[0002] Roads are infrastructure for various trackless vehicles and pedestrians to pass through. Road construction is an important part of my country's transportation construction. In road construction, it is usually necessary to first construct the roadbed in advance at the construction site, and then use templates to fence off on both sides of the roadbed. Then fill the roadbed with soil and sand and compact it to be able to withstand construction vehicles. Then, remove stones and other debris in the roadbed. In dry weather, the roadbed needs to be watered, and finally concrete pouring, molding and maintenance work are carried out.

[0003] In the pouring of road concrete, a concrete tank truck is generally driven into the roadbed and the concrete in the concrete tank truck is poured into the roadbed through the discharge port. However, the discharge port of the existing concrete tank truck cannot automatically change the pouring direction, and it is often necessary to use manpower to push the discharge port to change the pouring direction, which makes the pouring very inconvenient. Secondly, the pouring direction adjustment range of the discharge port of the concrete tank truck is limited. Even if the pouring direction is changed by manpower, a large amount of manual paving work using tools such as shovels is still required. Finally, when changing the pouring direction, the discharge port of the concrete tank truck rotates with the rotating connection position as the rotation center, so that the path of concrete pouring is arc-shaped instead of pouring along the width direction of the roadbed, and manual paving work is also required. Therefore, there is an urgent need for a device that can assist concrete tank trucks in pouring concrete during road concrete pouring construction. Summary of the invention

[0023] With the above structure, the invention has the following advantages:

[0024] 1. The present invention enables large-scale pouring during the concrete pouring process. The poured concrete is poured back and forth along the width direction of the roadbed with uniformity, which reduces the time for manual paving work in the later stage and saves construction period.

[0025] 2. The present invention is provided with a reciprocating drive mechanism, through the motor output shaft of the reciprocating drive mechanism, the annular frame will be directly driven to rotate, so that the first vertical rod at the bottom of the annular frame will rotate around, and through the transmission of the connecting rod, the second vertical rod will drive the first sliding block to reciprocate longitudinally in the second longitudinal guide rail. At the same time, when the second vertical rod reciprocates longitudinally, the cross bar is slidably connected with the strip sliding cavity of the inner arc base, so the cross bar will drive the inner arc base to swing back and forth, so that the rotating shaft will rotate back and forth, thereby realizing automatic reciprocating casting, without the need for human operation, and greatly improving the casting efficiency.

The first vertical rod fixed to the second slider will also change the distance between the second slider and the center of the annular frame, so that when the first vertical rod rotates around following the rotation of the annular frame, the range of the reciprocating motion of the second vertical rod can be changed by pulling the connecting rod, thereby changing the reciprocating rotation angle of the rotating shaft, and further regulating the casting range of the casting pipe in the roadbed width direction; if the roadbed width is small, the second slider is adjusted in the direction close to the center of the annular frame so that the casting pipe adapts to the casting range of the small-width roadbed; if the roadbed width is large, the second slider is adjusted in the direction away from the center of the annular frame so that the casting pipe adapts to the casting range of the large-width roadbed.

[0027] 4. The device is also provided with a paving assembly, which allows the concrete to be further dispersed and spread into the roadbed after pouring;

[0028] 5. The L-shaped bracket of the paving component is set as a telescopic rod. The guide rod fixed to the movable end of the telescopic rod can move along the wavy guide groove of the second strip plate, and vibrate up and down while each vertical rod moves back and forth longitudinally. It can effectively spread and vibrate the concrete that has been poured behind the inclined pipe, so that the concrete can be spread automatically during pouring, reducing the workload and time of subsequent manual paving, and greatly facilitating the construction period of road concrete pouring.

[0029] In summary, the present invention can achieve large-scale pouring by automatic swinging during the concrete pouring process, and the poured concrete is poured back and forth along the width of the roadbed with uniformity, thereby reducing the time required for manual paving in the later stage and saving construction time.

DETAILED DESCRIPTION

[0043] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0044] Embodiment 1,

[0045] like Figures 1 to 6 A road construction concrete pouring device shown includes a tractor 001, a concrete pump 002 is integrated and installed on the front side of the tractor 001, and a pouring system is arranged on the rear side of the tractor 001. The pouring system includes a connecting mechanism, a pouring pipeline mechanism, a guide rail mechanism and a reciprocating drive mechanism, wherein:

[0046] The connecting mechanism includes a rotating shaft 100 rotatably arranged at the rear side of the traction trolley 001, and a locking fixture is arranged at the top of the rotating shaft 100;

[0047] The pouring pipeline mechanism includes an outer sleeve 110 and a telescopic pipe 111. One end of the outer sleeve 110 is connected and fixed to the rotating shaft 100 through a locking fixture and extends backward.

[0048] like Figure 2 As shown, the locking fixture includes an inner arc base 101 and an inner arc upper cover 102 that match the shape of the outer sleeve 110. The inner arc base 101 is fixedly installed on the top of the rotating shaft 100. The inner arc upper cover 102 and the inner arc base 101 are connected and fixed by bolts. The outer sleeve 110 set on the inner arc base 101 is locked and fixed by fixing the inner arc upper cover 102 and the inner arc base 101. A connecting sleeve 113 coaxially arranged with the rotating shaft 100 is fixedly arranged on the top of the outer sleeve 110. A rotating drum 114 is rotatably mounted on the connecting sleeve 113. The rotating drum 114 is connected to the discharge end of the concrete pump 002 through a connecting pipe 115. The telescopic pipe 111 is slidably sleeved on the rear side of the outer sleeve 110 and extends backward. A vertically extending casting pipe 112 is processed at the rear end of the telescopic pipe 111.

[0049] like Figure 3 As shown, the guide rail mechanism includes a first longitudinal guide rail 120 extending longitudinally, the longitudinal sides of the traction trolley 001 are fixedly connected to the two ends of the first longitudinal guide rail 120 through brackets 121 respectively, and the casting pipe 112 is slidably assembled on the first longitudinal guide rail 120, and the casting pipe 112 is positioned by the first longitudinal guide rail 120;

[0050] The reciprocating drive mechanism is installed between the rear side of the traction trolley 001 and one of the brackets 121, and the reciprocating drive mechanism is used to drive the rotating shaft 100 to reciprocate.

[0051] In this embodiment, the concrete pump 002 is a prior art, which generally includes a pump unit and a hopper. In the actual process, the tractor 001 can be connected to the concrete tanker, and then the concrete tanker introduces the concrete in the concrete pump 002 into the hopper, and the concrete in the hopper is pumped out through the discharge end by the pump unit. The principle and structure are not introduced here, and only the functionality is explained;

[0052] Before putting the device into use, Figure 1 Install as shown, then connect the tractor 001 to the concrete tanker, and align the discharge port of the concrete tanker with the hopper of the concrete pump 002, so that the concrete tanker can discharge the concrete into the hopper;

[0053] When using it, the following work flow is included:

[0054] ① The concrete tank truck introduces concrete into the hopper of the concrete pump 002 through the discharge port, and the concrete is pumped out of the hopper through the pump unit of the concrete pump 002. The concrete is transported through the connecting pipe 115, the rotating drum 114, the connecting sleeve 113, the outer sleeve 110 and the telescopic pipe 111 in sequence, and finally sent downward to the roadbed through the pouring pipe 112;

[0055] ②At the same time as step ①, start the reciprocating drive mechanism to drive the rotating shaft 100 to reciprocate. Since the top of the rotating shaft 100 is fixed to the outer sleeve 110 by a locking fixture, the fixing work needs to be completed before use. The specific fixing method is:

[0056] Put the outer sleeve 110 into the inner arc base 101 of the locking fixture, then cover the inner arc upper cover 102 on the top of the outer sleeve 110, and connect and fix the inner arc base 101 and the inner arc upper cover 102 with bolts to complete the fixing of the outer sleeve 110 and the rotating shaft 100;

[0057] When the rotating shaft 100 reciprocates, the outer sleeve 110 can follow the rotating shaft 100 and reciprocate based on the central axis of the rotating shaft 100.

[0058] ③ When the outer sleeve 110 swings back and forth, the telescopic tube 111 and the pouring tube 112 are driven to swing back and forth. At the same time, since the outer sleeve 110 and the telescopic tube 111 are extended to the rear side, the swing range of the pouring tube 112 at the end of the telescopic tube 111 will be greatly increased, so as to adapt to the width of the roadbed. In addition, through the setting of the guide rail mechanism, during the swinging process of the pouring tube 112, it will always reciprocate along the first longitudinal guide rail 120, and the telescopic tube 111 will also adaptively extend and retract relative to the outer sleeve 110, so that the concrete is always poured along the roadbed width direction during the roadbed pouring process;

[0059] In this way, by utilizing the technical solution of this embodiment, large-scale pouring can be achieved during the concrete pouring process. The poured concrete is poured back and forth along the width of the roadbed with uniformity, which reduces the time required for manual paving in the later stage and saves construction time.

[0060] As a further explanation of the reciprocating drive mechanism in this embodiment,

[0061] like Figures 1 to 6 As shown, the reciprocating drive mechanism includes a motor 130, a drive assembly, a guide rail assembly and a connecting assembly. The motor 130 is installed on the upper side of the bracket 121, and the output shaft of the motor 130 passes through the bracket 121 downward;

[0062] The driving assembly includes a horizontally arranged annular frame 131, which is coaxially fixed on the output shaft of the motor 130;

[0063] The guide rail assembly includes a second longitudinal guide rail 132, which is arranged in parallel with the first longitudinal guide rail 120, and the second longitudinal guide rail 132 is fixedly arranged at the rear side of the traction trolley 001;

[0064] The connecting assembly includes a first vertical rod 133, a first slider 134 and a connecting rod 135. The first slider 134 is slidably connected to the second longitudinal guide rail 132. The second vertical rod 136 is installed on the top of the first slider 134. The first vertical rod 133 is installed at the bottom of the outer circle of the annular frame 131. Both ends of the connecting rod 135 are rotatably assembled on the first vertical rod 133 and the second vertical rod 136 respectively.

[0065] A cross bar 137 is disposed on the upper side of the second vertical bar 136 . A strip sliding cavity is provided on the inner arc base 101 . The strip sliding cavity is arranged parallel to the outer sleeve 110 . The cross bar 137 is inserted into the strip sliding cavity and is slidably connected to the strip sliding cavity.

[0066] The principle of the reciprocating drive mechanism is as follows:

[0067] When the motor 130 is turned on, the output shaft of the motor 130 will directly drive the annular frame 131 to rotate, so that the first vertical rod 133 at the bottom of the annular frame 131 rotates around, and the second vertical rod 136 drives the first slider 134 to reciprocate longitudinally in the second longitudinal guide rail 132 through the transmission of the connecting rod 135. At the same time, when the second vertical rod 136 reciprocates longitudinally, it is slidably connected with the strip-shaped sliding cavity of the inner arc-shaped base 101 through the cross bar 137, so that the cross bar 137 drives the inner arc-shaped base 101 to swing back and forth, so that the rotating shaft 100 reciprocates.

[0068] During this process, the crossbar 137 will adaptively extend and retract the strip-shaped sliding cavity relative to the inner arc-shaped base 101.

[0069] At the same time, on the basis of the above technical solution, in order to further make the swing range of the pouring pipe 112 adjustable to adapt to a roadbed with a wider range of widths, the following improvements are made:

[0070] like Figures 3 to 6 As shown, the reciprocating drive mechanism is also provided with a swing amplitude adjustment component, which includes a strip through slot 140 and a second slider 141 slidably arranged inside the strip through slot 140, the strip through slot 140 is opened in the annular frame 131 and is radially arranged along the annular frame 131, the strip through slot 140 is rotatably connected with an adjusting screw 142, the second slider 141 is threadedly connected to the adjusting screw 142, the end of the adjusting screw 142 extends from the outside of the annular frame 131, and a knob for facilitating the rotation of the adjusting screw 142 is installed on it, the first vertical rod 133 is fixed to the bottom of the second slider 141, and the first vertical rod 133 is perpendicular to the annular frame 131.

[0071] During the adjustment process, the second slider 141 is moved in the strip-shaped through groove 140 by operating the adjustment screw 142, and the distance between the second slider 141 and the center of the annular frame 131 is changed. The first vertical rod 133 fixed to the second slider 141 will also change the distance between the first vertical rod 133 and the center of the annular frame 131, so that when the first vertical rod 133 rotates around following the rotation of the annular frame 131, the reciprocating range of the second vertical rod 136 pulled by the connecting rod 135 can be changed, thereby changing the reciprocating angle of the rotating shaft 100, and further regulating the casting range of the casting pipe 112 in the width direction of the roadbed;

[0072] If the roadbed width is small, the second slider 141 is adjusted toward the center of the annular frame 131 so that the casting pipe 112 can adapt to the casting range of the small width roadbed. If the roadbed width is large, the second slider 141 is adjusted toward the center of the annular frame 131 so that the casting pipe 112 can adapt to the casting range of the large width roadbed.

[0073] As a further optimization of this embodiment, Figure 1 As shown, an arc-shaped positioning rail 150 is commonly provided between the brackets 121 on both sides, a third sliding block 151 is slidably connected to the arc-shaped positioning rail 150 , and the bottom of the outer sleeve 110 is fixedly mounted to the third sliding block 151 .

[0074] Such an arrangement makes the swing of the outer sleeve 110 more stable. At the same time, the arc-shaped positioning rail 150 and the third slider 151 can further support the outer sleeve 110, thereby improving the stability of the installation of the outer sleeve 110.

[0075] Embodiment 2,

[0076] Example 2 is an improvement made on the basis of Example 1 in order to further disperse and spread the concrete into the roadbed after pouring;

[0077] like Figures 7 to 10 As shown, a downward discharge pipe 200 is provided at the rear end of the telescopic tube 111, and the casting tube 112 includes a connecting portion 201, a rectangular tube 202 and a discharge pipe 203 integrally formed from top to bottom, the discharge pipe 200 is rotatably matched with the connecting portion 201, the rectangular tube 202 is slidably installed in the first longitudinal guide rail 120 and does not rotate, the rectangular tube 202 passes through the first longitudinal guide rail 120, and the bottom of the discharge pipe 203 is also connected to an oblique pipe 204, and the lower side of the oblique pipe 204 extends toward the direction of the traction trolley 001;

[0078] An L-shaped bracket 210 extending vertically downward is fixedly connected to the outer wall of the connecting portion 201, and a paving assembly is installed at the bottom of the L-shaped bracket 210;

[0079] The paving assembly includes a first strip plate 211 arranged perpendicularly to the first longitudinal guide rail 120, a plurality of vertical rods 212 are arranged at the bottom of the first strip plate 211, and a plurality of arc-shaped protrusions are processed on the outer wall surface of each vertical rod 212, which are not shown in the figure;

[0080] like Fig.10 The vertical section of the L-shaped bracket 210 is a telescopic rod 2101, and a second strip plate 220 is installed on the first longitudinal guide rail 120 along the length direction. A wavy guide groove 221 is opened on the second strip plate 220 along the length direction. The movable end of the telescopic rod 2101 is fixedly connected with a guide rod 2102 matching the guide groove 221, and the guide rod 2102 is inserted into the guide groove 221, and the guide rod 2102 is slidably connected to the guide groove 221.

[0081] The discharge pipe 200 is rotatably connected to the connection part 201 of the pouring pipe 112 at the rear end of the telescopic pipe 111, so that when the telescopic pipe 111 swings back and forth, the discharge pipe 200 can rotate relative to the connection part 201, while the connection part 201 does not rotate due to the positioning of the rectangular tube 202 and the first longitudinal guide rail 120. The concrete is transported through the telescopic pipe 111, the discharge pipe 200, the connection part 201, the rectangular tube 202 and the discharge pipe 203 in sequence, and finally discharged from the oblique pipe 204, so that the concrete is poured forward in the direction of the traction trolley 001;

[0082] Since the connection part 201 will not rotate under the positioning of the rectangular tube 202 and the first longitudinal guide rail 120, the L-shaped bracket 210 connected to the connection part 201 will not change position during the reciprocating motion along the width direction of the roadbed, so that the concrete poured behind the oblique pipe 204 can be paved through the reciprocating motion of the multiple vertical rods 212 at the bottom of the first strip plate 211 of the paving assembly, and multiple arc-shaped protrusions can be processed on the outer wall surface of the vertical rods 212 to improve the paving effect;

[0083] At the same time, the vertical section of the L-shaped bracket 210 is processed into a telescopic rod 2101. When the L-shaped bracket 210 reciprocates, the guide rod 2102 fixed to the movable end of the telescopic rod 2101 can move along the wave-shaped guide groove 221 of the second strip plate 220, so that the telescopic rod 2101 of the L-shaped bracket 210 can reciprocate up and down, thereby making each vertical rod 212 reciprocate up and down.

[0084] While each vertical rod 212 reciprocates longitudinally and vibrates up and down, it can effectively spread and vibrate the concrete that has been poured behind the inclined pipe 204, so that the concrete can be spread automatically during pouring, reducing the workload and time of subsequent manual spreading, and greatly facilitating the construction period of road concrete pouring.

[0085] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
