Description

Technical Field

[0001] This utility model specifically relates to the field of troweling machine technology, and more specifically to a cement troweling machine for water conservancy riverbank protection. Background Technology

[0002] The cement troweling machine for riverbank protection is a key piece of equipment used in the construction and maintenance of water conservancy projects to treat the cement surface of slope protection, which can improve the stability and durability of the slope protection.

[0003] Currently common cement troweling machines for slope protection are roller-type trowels: These trowels typically consist of a U-shaped frame and troweling rollers. For example, in a water conservancy construction slope protection troweling device, a troweling roller is rotatably mounted on the inner crossbar of the U-shaped frame. During operation, the troweling roller rolls on the slope surface, relying on its own weight and the pressure generated by rotation to compact and smooth the cement surface.

[0004] However, the roller trowel mentioned above could not distribute the surrounding cement, resulting in pits and depressions after the slope was formed, which eventually led to cracking of the slope. Utility Model Content

[0005] The purpose of this utility model is to provide a cement smoothing machine for riverbank protection, which uses a high-speed rotating grinding disc to smooth the surrounding cement, thereby ensuring the solidity of the cement and avoiding hollow areas or pits, thus ensuring the quality of the slope protection; and solving the technical problems mentioned in the background art above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cement smoothing machine for riverbank protection in water conservancy, including

[0008] Trusses, used for smoothing and installing components, are set parallel to the riverbank protection.

[0009] Two smoothing components are provided, symmetrically installed on both sides of the truss;

[0010] The hoisting mechanism, used for smoothing component drive, is located inside the truss;

[0011] The two ends of the truss are fixed to the first gantry hanger and the second gantry hanger, respectively.

[0012] As a further technical solution of this utility model, the first door hanger and the second door hanger adopt the same structure, and multiple plum blossom handle bolts for quick locking and fixing of the truss are provided on both sides of the first door hanger and the second door hanger.

[0013] As a further technical solution of this utility model, the bottom of both the first and second gantry hangers is fixed with a sliding seat, which is then slidably connected to the track pre-embedded in the river channel or at the top of the slope.

[0014] As a further technical solution of this utility model, a hand-operated hoist is fixedly installed on the top of the inner side of both the first and second gantry cranes, and the hook of the hand-operated hoist is fixed to the truss.

[0015] As a further technical solution of this utility model, the winch mechanism includes a winch and a speed reducer unit for driving the winch. The winch is provided with a wire rope, which is used for the traction and reciprocating movement of the smoothing component.

[0016] As a further technical solution of this utility model, the smoothing component includes a frame body, a top plate is fixed on the top of the frame body, and a sliding seat is also provided on one side of the upper end of the frame body. The sliding seat is fixed to the bottom of the top plate and is slidably connected to the slide rail installed on the truss.

[0017] As a further technical solution of this utility model, a speed reducer is installed on the top plate. The speed reducer works with a synchronous belt, a synchronous pulley, and a gear that is installed in conjunction with the lead screw to drive the lead screw to rotate.

[0018] Guide rods are provided on both sides of the lead screw, and sliding brackets are slidably connected to the two guide rods. The sliding brackets are also threadedly connected to the lead screw.

[0019] A mounting bracket is fixed to the outer side of the sliding frame, and a rotary motor is fixed to the inner side of the mounting bracket; a grinding disc is mounted on the output shaft of the rotary motor.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. In this utility model, due to the different inclinations of the slope, the height of both ends of the truss can be controlled by adjusting the allowance of the two hand-operated hoist chains, thereby achieving the overall inclination adjustment of the truss; this ensures the fit between the smoothing component and the slope surface, thus facilitating the smoothing of cement on the slope.

[0022] 2. This utility model features two smoothing components: one performs initial smoothing of the cement on the slope, and the other performs final smoothing. This ensures the solidity of the cement on the slope, thereby guaranteeing the quality of the cement slope protection and preventing hollow areas and pits.

[0023] 3. In this utility model, the reducer unit is equipped with a synchronous belt, a synchronous pulley, and a gear that is installed in conjunction with the lead screw, thereby driving the lead screw to rotate. The sliding frame converts the rotational motion of the lead screw into linear motion, which moves up and down along the guide rod, thereby adjusting the contact gap between the grinding disc and the slope protection.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-7 In this embodiment of the utility model, a cement smoothing machine for riverbank protection includes a truss 5, which is used for the installation of the smoothing component 7 and is arranged parallel to the riverbank protection. A hand-operated hoist 4 is fixedly installed on the top of the inner side of both the first gantry crane 1 and the second gantry crane 2, and the hook of the hand-operated hoist 4 is fixed to the truss 5. The first gantry crane 1 and the second gantry crane 2 are composed of the same structure.

[0035] More specifically, the truss 5 is installed in a detachable manner with the first door hanger 1 and the second door hanger 2; multiple plum blossom handle bolts for quick locking and fixing of the truss 5 are provided on both sides of the first door hanger 1 and the second door hanger 2.

[0036] Since the slope slopes are of different inclinations, the height of both ends of the truss 5 can be controlled by adjusting the allowance of the chains of the two hand-operated hoists 4, thereby adjusting the overall inclination of the truss 5; this ensures that the smoothing component 7 fits the slope surface, making it easier to smooth the cement on the slope slope.

[0037] After the inclination of truss 5 is adjusted, use the Phillips head bolts to lock and fix truss 5 to prevent shaking during operation.

[0038] In this embodiment, two smoothing components 7 are provided and are symmetrically installed on both sides of the truss 5.

[0039] Two smoothing components 7 are used: one for initial smoothing of the cement on the slope, and the other for final smoothing. This ensures the cement on the slope is solid, thus guaranteeing the quality of the cement slope protection and preventing hollow areas and pits.

[0040] In this embodiment, a hoisting mechanism 6 is also included. The hoisting mechanism 6, which drives the smoothing component 7, is located inside the truss 5. The hoisting mechanism 6 includes a hoist and a speed reducer unit for driving the hoist. A steel wire rope is provided on the hoist, which is used for traction and reciprocating movement of the smoothing component 7.

[0041] Furthermore, a fixed pulley is fixed to the truss 5 near the first gantry 1, and a fixed pulley is provided on the inner side of the smoothing component 7; one end of the wire rope on the hoisting mechanism 6 is pulled out, passes around the two fixed pulleys, and is fixed to the end of the truss 5 near the first gantry 1; when the hoisting mechanism 6 rotates clockwise, the wire rope is tightened, and the smoothing component 7 slides upward along the slide rail 8.

[0042] When the hoisting mechanism 6 rotates counterclockwise, the wire rope is released. At this time, the truss 5 is in an inclined state, and the smoothing component 7 slides downward under its own weight, thereby realizing the reciprocating movement of the smoothing component 7 to facilitate the smoothing treatment of the slope.

[0043] As a further explanation of the above technical solution, the way the steel wire rope is laid is only one of the many ways to drive the smoothing component 7. This explanation is only to further illustrate the feasibility of driving the smoothing component 7. Other embodiments will not be described in detail.

[0044] In this embodiment, the bottom of both the first gantry 1 and the second gantry 2 is fixed with a sliding seat 3, and the sliding seat 3 is slidably connected to the track pre-embedded in the river channel or the top of the slope.

[0045] By adopting the above technical solution, the first gantry 1 and the second gantry 2 can move through the bottom slide 3 and the track, which facilitates the movement of the entire screed machine along the river.

[0046] In this embodiment, the smoothing component 7 includes a frame body 71, and a top plate 72 is fixed on the top of the frame body 71. A sliding seat 713 is also provided on one side of the upper end of the frame body 71. The sliding seat 713 is fixed to the bottom of the top plate 72 and is slidably connected to the slide rail 8 installed on the truss 5.

[0047] The sliding seat 713 enables the smoothing component 7 to move stably along the truss 5, thereby facilitating the smoothing of cement on the slope.

[0048] In this embodiment, a speed reducer 73 is installed on the top plate 72. A synchronous pulley 75 is installed at the power output end of the speed reducer 73. The synchronous pulley 75 installed on the speed reducer 73 is connected to another synchronous pulley 75 coaxially arranged with the gear 76 via a synchronous belt 74. There are two gears 76, and the other gear 76 is installed on the lead screw 77. The two gears 76 mesh and drive each other.

[0049] Guide rods 78 are provided on both sides of the lead screw 77, and sliding brackets 79 are slidably connected to the two guide rods 78. The sliding brackets 79 are also threadedly connected to the lead screw 77.

[0050] A mounting bracket 710 is fixed to the outer side of the sliding frame 79, and a rotary motor 711 is fixed to the inner side of the mounting bracket 710; a grinding disc 712 is fitted onto the output shaft of the rotary motor 711. The reducer unit 73, the rotary motor 711, and the hoisting mechanism 6 are all connected to the distribution box 9 via wires; the distribution box 9 is fixed to one end of the truss 5.

[0051] By adopting the above technical solution, the reducer 73 works in conjunction with the synchronous belt 74, the synchronous pulley 75, and the gear 76 that is installed in conjunction with the lead screw 77, thereby driving the lead screw 77 to rotate. The sliding frame 79 converts the rotational motion of the lead screw 77 into linear motion, which moves up and down along the guide rod 78, thereby adjusting the fit gap between the grinding disc 712 and the slope protection.

[0052] The rotary motor 711 drives the grinding disc 712 to rotate at high speed, thereby smoothing the cement on the slope. With the adjustment of the gap between the grinding disc 712 and the slope, the cement can be smoothed better, thus avoiding the occurrence of hollow spots and depressions on the slope.

[0053] The working principle of this utility model is as follows: When the hoisting mechanism 6 rotates counterclockwise, the wire rope is released. At this time, the truss 5 is in an inclined state, and the smoothing component 7 slides downward under its own gravity, thereby realizing the reciprocating movement of the smoothing component 7. The reducer 73 cooperates with the synchronous belt 74, the synchronous pulley 75 and the gear 76 installed with the lead screw 77, thereby driving the lead screw 77 to rotate. The sliding frame 79 converts the rotational motion of the lead screw 77 into linear motion, which moves up and down along the guide rod 78, thereby adjusting the fit gap between the grinding disc 712 and the slope protection.

[0054] The rotary motor 711 drives the grinding disc 712 to rotate at high speed, thereby smoothing the cement on the slope. With the adjustment of the gap between the grinding disc 712 and the slope, the cement can be smoothed better, thus avoiding the occurrence of hollow spots and depressions on the slope.
