For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0026] Example 1 See also Figures 1 to 7 The present invention provides a roof concrete gutter finishing device, comprising a frame 1 and a forming mechanism 2 rotatably arranged on the frame 1, wherein the forming mechanism 2 is used for extrusion forming of gutter concrete; A front wheel 3 is rotatably arranged at the front end of the frame 1, and a rear wheel 4 is rotatably arranged at the rear end, and the two rear wheels 4 are fixedly connected via a transmission shaft 5; It also includes a control mechanism 6 for controlling the slope of the gutter, and the control mechanism 6 is linked to the transmission shaft 5.

[0027] The forming mechanism 2 includes a working frame 7 rotatably arranged on the frame 1, the rotating axis of the working frame 7 is coaxial with the transmission shaft 5, one end of the working frame 7 is rotatably connected to the frame 1, and a screw rod 8 is rotatably arranged in the middle of the other end, a sleeve 9 is sleeved on the screw rod 8, the sleeve 9 is rotatably connected to the middle of the frame 1, a knob 10 is rotatably arranged on the sleeve 9, and the knob 10 is threadedly connected to the screw rod 8; A mounting frame 11 is fixedly arranged in the middle of the working frame 7 , and a molding unit 12 is arranged on the mounting frame 11 .

[0028] When the gutter concrete needs to be extruded, the work frame 7 is placed in a horizontal state. At this time, the molding unit 12 on the mounting frame 11 is in contact with the gutter concrete and can perform an extrusion molding operation on it. The molding unit 12, supported by the work frame 7, functions stably to ensure that the shape of the gutter meets the requirements. If the device needs to be moved or the position needs to be adjusted, when adjusting the screw rod 8, the knob 10 on the sleeve 9 is rotated to make the screw rod 8 move up and down under the action of the inner thread of the knob 10. The movement of the screw rod 8 drives one end of the working frame 7 to rise, thereby tilting the working frame 7. When the working frame 7 is tilted, the molding unit 12 tilts accordingly, and will not interfere with the ground, and will not affect the movement of the device, so that the device can be conveniently moved to different positions for construction operations.

[0029] The molding unit 12 includes an I-shaped mounting plate 13, and a rubber pad 14 is respectively arranged at the four corners of the mounting plate 13. The rubber pad 14 is usually made of a rubber material with good elasticity and wear resistance, and can play a role in buffering and shock absorption when the molding mold 17 is working. When the vibration motor 16 drives the vibration frame 15 to vibrate, the rubber pad 14 can absorb and reduce the impact force transmitted by the vibration to the mounting plate 13 and the entire device, reduce the risk of wear and damage of the device caused by vibration, and extend the service life of the device; the vibration frame 15 is arranged on the rubber pad 14, and the vibration motor 16 is fixedly arranged on the vibration frame 15; A forming mold 17 can also be detachably arranged on the vibration frame 15 .

[0030] The vibration frame 15 includes an I-shaped fixing plate corresponding to the mounting plate 13, and hangers are arranged at the four corners of the fixing plate, the vibration motor 16 is fixed on the hanger, and the forming mold 17 is detachably connected to the hanger; this design enables the vibration motor 16 to be stably fixed on the vibration frame 15, and the structure of the fixing plate and the hanger provides reliable support for the vibration motor 16; at the same time, the detachable connection between the forming mold 17 and the hanger facilitates the replacement of forming molds 17 of different shapes and specifications under different construction requirements, thereby improving the applicability and flexibility of the device; during the construction process, the vibration generated by the vibration motor 16 is transmitted to the forming mold 17 through the hanger, thereby enabling the forming mold 17 to effectively extrude and compact the gutter concrete, thereby improving the quality and durability of the gutter; in addition, the I-shaped fixing plate structure not only increases the strength and stability of the vibration frame 15, but also facilitates connection and fixation with the mounting plate 13, thereby ensuring the firmness and reliability of the entire forming unit 12.

[0031] When using the roof concrete gutter finishing device, when the work frame 7 is in a suitable position to perform the gutter concrete finishing operation, the I-shaped mounting plate 13 in the molding unit 12 provides a stable support structure for the entire molding unit 12, and the rubber pads 14 at the four corners of the mounting plate 13 play a role in buffering and shock absorption, reducing the adverse effects of vibration on other parts of the device.

[0032] The vibration motor 16 is started, and the vibration motor 16 drives the vibration frame 15 to vibrate. On the one hand, the vibration frame 15 transmits the vibration to the forming mold 17, so that when the forming mold 17 extrude and mold the gutter concrete, the concrete can be made more compact by vibration, thereby improving the quality of the gutter. On the other hand, during the vibration process, the vibration frame 15 uses the cushioning effect of the rubber pad 14 to ensure that the vibration is transmitted within a reasonable range, thereby avoiding damage to the device caused by excessive vibration.

[0033] The molding mold 17 in the molding unit 12 can be easily removed from the vibration frame 15. Specifically, it can be connected by snap-fit ​​connection, bolt connection, pin connection, etc. When the molding mold 17 of different shapes or specifications needs to be replaced, the disassembly and assembly operation can be completed quickly and efficiently, thereby improving construction efficiency.

[0034] The forming mold 17 can effectively achieve the finishing of the concrete during the vibration process. When the vibration motor 16 is started, the vibration is transmitted to the forming mold 17 through the hanger, so that the forming mold 17 generates high-frequency vibration. The vibration can also make the concrete surface smoother. The vibration of the forming mold 17 promotes the uniform distribution of the slurry on the concrete surface, eliminates the unevenness and defects of the surface, and achieves a high-quality finishing effect.

[0035] In addition, the vibration process can also help expel bubbles in the concrete. The presence of bubbles will reduce the strength and impermeability of the concrete, while vibration can make the bubbles rise and escape from the concrete surface, further improving the quality of the concrete.

[0036] In response to various gutter design requirements and drainage needs, the cross-sectional shape of the gutter may have a variety of options such as U-shape, V-shape, inverted trapezoid, etc. The currently commonly used gutter shape is inverted trapezoid. Inverted trapezoidal gutters have advantages in stability and bearing capacity. The wider top and gradually narrowing bottom structure enable the gutters to withstand greater water flow impact and debris accumulation. This shape of gutter is also easy to clean and maintain, and can effectively prevent blockage, ensuring the long-term stable operation of the drainage system.

[0037] Gutters of different shapes can be selected according to factors such as the building style, geographical location, and climatic conditions to meet a variety of design requirements and drainage needs, providing a reliable drainage solution for the building.

[0038] Four screws 18 are also fixedly arranged on the working frame 7, and each screw 18 is located at a corner close to the rubber pad 14; The screw rod 18 is movably connected to the mounting frame 11; A plurality of adjusting wheels 19 are rotatably arranged on the mounting frame 11 , each adjusting wheel 19 corresponds to one of the screw rods 18 , and each adjusting wheel 19 is provided with a threaded hole, through which the adjusting wheel 19 is threadedly connected to the screw rod 18 .

[0039] When using the roof concrete gutter finishing device, the four screws 18 fixed on the working frame 7 are respectively located at the corners close to the rubber pad 14, providing a stable connection support for the mounting frame 11. The screws 18 are movably connected to the mounting frame 11, so that the mounting frame 11 can be adjusted in position within a certain range.

[0040] Several adjusting wheels 19 rotatably arranged on the mounting frame 11 correspond one to one with the screw rod 18, and a threaded hole provided on each adjusting wheel 19 is threadedly connected with the screw rod 18. When it is necessary to construct gutters of different depths, by rotating the adjusting wheel 19, due to the thread matching between the adjusting wheel 19 and the screw rod 18, the rotation of the adjusting wheel 19 will cause the mounting frame 11 to move up and down along the screw rod 18, thereby realizing the adjustment of the horizontal height of the forming mold 17.

[0041] For example, when facing a deeper gutter, by rotating the adjusting wheel 19, the mounting frame 11 drives the forming mold 17 to descend, so that the forming mold 17 can fully contact the deeper gutter concrete for extrusion molding operation; when encountering a shallower gutter, the adjusting wheel 19 is rotated in the opposite direction, the mounting frame 11 rises, and the forming mold 17 is raised to an appropriate height, ensuring that the forming mold 17 can effectively act on the concrete of the shallower gutter, meet the construction requirements of gutters of different depths, and improve the applicability and flexibility of the device.

[0042] The control mechanism 6 includes a driving sprocket 20 rotatably disposed on one side of the mounting frame 11 , and sprocket teeth meshing with a chain 21 are disposed on the outer peripheral wall of each adjusting wheel 19 , and the driving sprocket 20 and the plurality of adjusting wheels 19 are connected via the chain 21 .

[0043] Furthermore, a guide wheel is also provided on the mounting frame 11, and the guide wheel can guide and constrain the movement direction of the chain 21, ensuring that the chain 21 maintains a stable running trajectory during the transmission process and is always engaged with the driving sprocket 20 and the adjusting wheel 19, thereby effectively preventing the chain 21 from being derailed, stuck, or other faults.

[0044] The gutter slope plays a vital role in the roof drainage system. The appropriate gutter slope can ensure that rainwater flows quickly and smoothly to the drain outlet, avoiding water accumulation and leakage problems.

[0045] The design of the gutter slope needs to consider many factors. First, the size of the slope should be determined according to the local rainfall and climatic conditions. Areas with heavy rainfall usually require a larger slope to ensure that rainwater can be discharged in time. Secondly, the shape and area of ​​the building's roof will also affect the design of the gutter slope. For roofs with larger areas, a steeper slope may be required to prevent rainwater from accumulating in the gutter. In addition, the material and construction quality of the gutter will also affect the effect of the slope.

[0046] When it is necessary to construct a gutter with a slope, the driving sprocket 20 is driven to rotate by an external power source such as a motor, and the rotation of the driving sprocket 20 is transmitted to each adjusting wheel 19 through the chain 21, so that the adjusting wheels 19 rotate synchronously. Since the adjusting wheels 19 are threadedly connected to the screw rod 18, the rotation of the adjusting wheels 19 will drive the mounting frame 11 to move up and down slowly, thereby changing the height position of the forming mold 17.

[0047] Then, by the movement of the frame 1, the height position of the forming mold 17 changes with the movement of the frame 1, thereby realizing the construction of the gutter with a slope.

[0048] A driven bevel gear 22 is coaxially fixedly arranged on the driving sprocket 20; A driving bevel gear 23 is sleeved on the transmission shaft 5. The driving bevel gear 23 slides axially with the transmission shaft 5 and is fixed radially. The position of the driving bevel gear 23 on the transmission shaft 5 can be moved manually. When the driving bevel gear 23 slides to a position close to and meshing with the driven bevel gear 22, the rotational power of the transmission shaft 5 can be transmitted to the driven bevel gear 22 through the driving bevel gear 23. The rotation of the driven bevel gear 22 further drives the driving sprocket 20 fixed coaxially therewith to rotate, thereby starting the linkage between the transmission shaft 5 and the control mechanism 6. When constructing the flat gutter, it is only necessary to slide the driving bevel gear 23 to a position away from the driven bevel gear 22. Furthermore, a locking bolt is also provided on the driving bevel gear 23. When the driving bevel gear 23 slides to a specific position, the driving bevel gear 23 can be firmly fixed to the transmission shaft 5 by tightening the locking bolt to prevent the driving bevel gear 23 from accidentally sliding during the operation of the device. This design makes it possible to flexibly choose whether to enable the gutter slope control function in different construction scenarios, thereby improving the adaptability and operational convenience of the device; when the driving bevel gear 23 is close to the driven bevel gear 22, the driving bevel gear 23 meshes with the driven bevel gear 22.

[0049] The driving bevel gear 23 and the driven bevel gear 22 are brought close to each other so that the two are meshed. The rotation of the transmission shaft 5 will drive the driven bevel gear 22 to rotate through the driving bevel gear 23, thereby driving the driving sprocket 20 to rotate. The rotation of the driving sprocket 20 is transmitted to each adjusting wheel 19 through the chain 21, so that the adjusting wheels 19 rotate synchronously. Since the adjusting wheels 19 are threadedly connected to the screw rod 18, the rotation of the adjusting wheels 19 will drive the mounting frame 11 to move up and down slowly, thereby changing the height position of the molding mold 17.

[0050] Then, by the movement of the frame 1, the height position of the forming mold 17 changes with the movement of the frame 1, thereby realizing the construction of the gutter with a slope.

[0051] The whole process is easy to operate and precisely controlled, which can greatly improve the quality and efficiency of gutter construction.

[0052] Furthermore, the diameter of the driven bevel gear 22 is larger than the diameter of the active bevel gear 23. When the active bevel gear 23 drives the driven bevel gear 22 to rotate, the rotation speed of the driven bevel gear 22 will be reduced accordingly, which makes the driving sprocket 20 coaxially fixed with the driven bevel gear 22 and the operation of the entire control mechanism 6 more stable; at the same time, the larger driven bevel gear 22 can also provide a larger torque output, ensuring that in the process of adjusting the gutter slope, even in the face of greater resistance, it can easily drive the adjusting wheel 19 to rotate, thereby achieving precise adjustment of the height position of the forming mold 17; this combination design of large and small gears fully considers the actual needs of gutter construction. In gutter construction, the accuracy requirements for the slope are often higher. Due to the large diameter of the driven bevel gear 22, its rotation speed is reduced, so that the rotation of the adjusting wheel 19 can be more finely controlled during the adjustment process, thereby achieving fine-tuning of the height position of the forming mold 17; this can ensure the accuracy of the gutter slope, and even small slope changes can be accurately controlled.

[0053] A handle 24 is fixedly provided on the frame 1; the user can easily push the device to move along the gutter through the handle 24, which greatly improves the convenience of operation; when holding the handle 24, downward pressure can be applied to the device, so that the forming mold 17 can be in closer contact with the gutter concrete, ensuring that the compaction and smooth finishing effect of the concrete can be better achieved during the vibration process.

[0054] When the present invention is used, the device is placed at the roof gutter to be constructed, and the working frame 7 is placed in a horizontal state. At this time, the molding unit 12 on the mounting frame 11 is in contact with the gutter concrete, and an extrusion molding operation can be performed on it; according to the design requirements and drainage requirements, a suitable molding mold 17 is selected; The vibration motor 16 is started, and the user pushes the device to move along the designed position of the gutter. The vibration motor 16 drives the vibration frame 15 to vibrate. On the one hand, the vibration frame 15 transmits the vibration to the forming mold 17, so that when the forming mold 17 extrude the gutter concrete, the concrete can be made more compact by vibration, thereby improving the quality of the gutter; it can also promote the uniform distribution of the slurry on the surface of the concrete, eliminate the unevenness and defects on the surface, and achieve a high-quality finishing effect.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
