Description

Technical Field

[0001] This invention relates to the field of foamed lightweight soil construction, and more particularly to a high-efficiency integrated construction device for foamed lightweight soil in road construction. Background Technology

[0002] Various building materials are required in the road construction process, and foamed cement and lightweight soil are among them. For example, the replacement of the roadbed behind the abutment of a newly built highway bridge can effectively solve the engineering settlement problem caused by insufficient preloading in soft soil sections. The replacement of the roadbed behind the abutment of an old road can completely solve the problem of bridge approach slab settlement caused by post-construction settlement in one go. The widening of the roadbed during road expansion can better solve the problem of differential deformation between the new and old roadbeds.

[0003] The production process of foamed cement lightweight soil generally involves using a foaming machine to mechanically foam the foaming agent, then uniformly mixing the foam with cement slurry, and finally using the pumping system of the foaming machine for on-site pouring or molding. After natural curing, it becomes a new type of lightweight thermal insulation material containing a large number of closed pores. In the construction of foamed cement lightweight soil, special construction equipment is required to pour it at the construction location.

[0004] Referring to the patent with announcement number 202110309805.4, in the existing foam lightweight soil construction device for road construction, the pouring pipe is generally adjusted by manually lifting it to adjust the spraying range (such as spraying angle and distance). However, when pouring foam lightweight soil by manually lifting the pouring pipe, the operator will experience certain fatigue after lifting for a long time, which will affect the pouring quality and reduce the construction efficiency.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Example: Please refer to Figure 1-4A high-efficiency integrated construction device for foamed lightweight soil in road construction includes a vehicle 1 and a foamed lightweight soil mixing mechanism 2 mounted on top of the vehicle 1. It also includes three quick-connect mechanisms 3 located on the side of the vehicle 1, an angle adjustment mechanism 5 detachably connected to the quick-connect mechanisms 3, and a quick-connect mechanism 3 located at the rear of the vehicle 1 connected to the vehicle 1 via a linear movement mechanism. The pouring pipe end of the foamed lightweight soil mixing mechanism 2 is fixedly connected to the output end of the angle adjustment mechanism 5. The foamed lightweight soil mixing mechanism 2 includes a mixing tank and an extraction pump connected to the mixing tank. The output end of the extraction pump is connected to the pouring pipe. The mixing tank can be a conventional, existing foamed lightweight soil mixing mechanism 2, which will not be elaborated further in this paper. The angle adjustment device allows for adjustment of the pouring pipe's angle. When the vehicle 1 moves or the power of the extraction pump changes, the pouring distance of the pouring pipe can be adjusted, thus eliminating the problem of reduced pouring quality and construction efficiency due to operator fatigue when manually lifting the pouring pipe. The detachable connection method mentioned above is a flange 16 connection.

[0027] In this embodiment, when the road 26 to be poured is relatively long, the vehicle 1 generally travels inside the road 26, and at this time, the angle adjustment mechanism 5 is connected to the quick-connect mechanism 3 installed at the rear end of the vehicle 1, so that the vehicle 1 can move while pouring, and at this time, the linear movement mechanism can realize the lateral movement of the pouring pipe, and the movement distance of the output end of the linear movement mechanism is greater than the width of the road 26, thereby realizing the full pouring of the road 26; when the road 26 is relatively short, the angle adjustment mechanism 5 can be connected to the quick-connect mechanism 3 on both sides of the vehicle 1, so that the vehicle 1 can carry out pouring while traveling outside the road 26.

[0028] In this embodiment, the linear movement mechanism can be a lead screw and nut mechanism 4, and the quick-connect mechanism 3 is fixed to the moving end of the lead screw and nut mechanism 4. The vehicle 1 is equipped with a motor 7 connected to the lead screw and nut mechanism 4 via belt drive. When the motor starts, the moving end of the lead screw and nut mechanism 4 will move, thereby driving the quick-connect mechanism 3 to move back and forth, which in turn causes the angle adjustment mechanism 5 to move back and forth, ultimately realizing the back and forth movement of the pouring pipe, thereby expanding the pouring area and improving the pouring quality. In addition, limit sensors are provided on both sides of the lead screw and nut mechanism 4 to limit the movement range of the quick-connect mechanism.

[0029] In this embodiment, the angle adjustment mechanism 5 includes a support base 14 connected to the quick-connect mechanism 3, a rotating frame 10 rotatably connected to the support base 14 for fixing the casting pipe, a hydraulic cylinder 23 for driving the rotating frame 10 to rotate, and a hydraulic system for adjusting the extension and retraction length of the hydraulic cylinder 23. The cylinder body of the hydraulic cylinder 23 is rotatably connected to the support base 14, and the end of the extension rod of the hydraulic cylinder 23 is rotatably connected to the rotating frame 10. The support base 14 and the rotating frame 10 are rotatably connected by bearings. The hydraulic system can be a conventional existing system for driving the extension and retraction of the hydraulic cylinder 23, which will not be described in detail here. When the hydraulic system is started, the extension rod of the hydraulic cylinder 23 will extend and retract, thereby driving the rotating frame 10 to rotate, thereby realizing the adjustment of the casting angle of the casting pipe.

[0030] In other embodiments, the rotating frame 10 is provided with a support rod 13 and a pipe clamping mechanism 22 connected to the middle of the support rod 13 and used to clamp the casting pipe. The pipe clamping mechanism 22 includes a lower pressure block 21 fixed to the support rod 13 and an upper pressure block 20 hinged to the lower pressure block 21. The ends of the lower pressure block 21 and the upper pressure block 20 away from the hinge are connected by bolts, thereby enabling the casting pipe to be quickly disassembled and assembled. The bolts are wing bolts, which further improves the convenience of disassembling and assembling the casting pipe.

[0031] In other embodiments, the casting pipe includes a transfer steel pipe 15 installed on the support base 14, and a casting steel pipe 19 connected to the transfer steel pipe 15 via a hose 1. The casting steel pipe 19 is clamped by the pipe clamping mechanism 22, and the output end of the extraction pump is connected to the transfer steel pipe 15 via a hose 2. The hose 2 and the transfer steel pipe 15 are connected by a quick-connect coupling, thereby realizing the rapid splicing of the casting pipe and improving the efficiency of casting. The hose 1 and hose 2 can effectively protect the casting pipe from being torn during the casting process.

[0032] In other embodiments, the rotating frame 10 includes two vertical rods 9 rotatably connected to the support base 14. The support rod 13 includes a movable rod 12 and a sliding sleeve 11 fixed to both ends of the movable rod 12. The sliding sleeve 11 is slidably connected to the vertical rod 9. A chain drive mechanism is provided on one of the vertical rods 9. The chain in the chain drive mechanism is fixedly connected to the sliding sleeve 11. When the chain rotates, it can drive the sliding sleeve 11 to move, thereby moving the support rod 13, and then moving the pipe clamping mechanism 22, realizing the up and down movement of the casting pipe.

[0033] In other embodiments, a second chain drive mechanism is provided on the vertical rod 9 that does not have a first chain drive mechanism. The chain of the second chain drive mechanism is fixedly connected to the sliding sleeve 11. A horizontal bar 8 is provided at the top of the two vertical rods 9. A transmission component for connecting the first chain drive mechanism and the second chain drive mechanism is provided on the horizontal bar 8. When the transmission component rotates, it drives the first chain drive mechanism and the second chain drive mechanism to rotate synchronously, causing the sliding sleeve 11 to move up and down simultaneously under force. This makes the support pipe and the pipe clamping mechanism 22 move up and down in a balanced manner under force, thereby improving the stability of the up and down movement of the pipe clamping mechanism 22, and thus improving the stability of the up and down movement of the casting pipe during casting.

[0034] A motor 17 is fixedly connected to the top of the vertical rod 9. The transmission assembly includes a transmission rod 18 rotatably connected inside the horizontal rod 8. The drive sprockets in both the chain drive mechanism 1 and the chain drive mechanism 2 are fixedly connected to the transmission rod 18. The transmission rod 18 is connected to the motor 17 via a belt drive. When the motor 17 starts, the transmission rod 18 rotates, causing the chain drive mechanism 1 and the chain drive mechanism 2 to rotate synchronously. This drives the sliding sleeves 11 at both ends of the support rod 13 to move up and down synchronously, causing the support rod 13 to move up and down. This, in turn, causes the pipe clamping mechanism 22 to move up and down, ultimately realizing the up and down movement of the casting pipe.

[0035] In other embodiments, a slide groove 25 is fixedly connected to one end of the support base 14 away from the hydraulic cylinder 23. A sliding block is provided inside the slide groove 25. One end of the limiting rod 24 is rotatably connected to the sliding block, and the other end of the limiting rod 24 is rotatably connected to the fixed block on the rotating frame 10. The fixed block secures the rotating frame 10 to the side opposite to the hydraulic cylinder 23; the two ends of the slide groove 25 are respectively provided with a limiting block one and a limiting block two; when the rotation angle of the rotating frame 10 is less than 90 degrees, the limiting rod 24 pulls the rotating frame 10, and the slider slides in the slide groove 25. When the slider slides to the limiting block one of the slide groove 25, the limiting rod 24 can protect the rotating frame 10, thereby preventing the rotating frame 10 from tipping over to one side; when the rotation angle of the rotating frame 10 is greater than or equal to 90 degrees, the limiting rod 24 pushes against the rotating frame 10, and the slider slides in the slide groove 25. When the slider slides to the limiting block two, the limiting rod 24 can protect the rotating frame 10, thereby preventing the rotating frame 10 from tipping over to the other side; thus, the protective function of the rotating frame 10 is achieved.

[0036] In other embodiments, a movable frame 6 is fixedly connected to the bottom of the support base 14. The bottom of the movable frame 6 is provided with several universal rollers, which are in contact with the ground. When the support base 14 is pulled by the vehicle 1, the movable frame 6 moves, which in turn drives the angle adjustment mechanism 5 to move, and finally realizes the movement of the pouring pipe, thereby providing further support for the rotating frame.

[0037] Working principle: When the construction of road 26 requires the pouring of foamed lightweight soil, as long as the pouring direction is selected according to the site conditions, the angle adjustment mechanism 5 is quickly connected to the corresponding position of vehicle 1. Then, by controlling the movement of vehicle 1 and controlling the extension length of the telescopic rod of hydraulic cylinder 23, the pouring direction of the pouring pipe can be controlled. This eliminates the problem of affecting the pouring quality and reducing construction efficiency due to operator fatigue when manually lifting the pouring pipe in the past.
