The quality of channel forming directly affects its subsequent use effect and lifespan. The flatness of the channel bottom is one of the important indicators of quality assessment. The leveling operation during the construction process is particularly important. Traditional channel bottom leveling methods mostly use manual handheld tools, which are not only labor-intensive and inefficient, but also difficult to guarantee the leveling effect. This problem is particularly prominent in large-scale and long-distance channel construction. With the continuous development of mechanized construction technology, channel forming slipform machines, as a highly efficient and precise channel construction equipment, have gradually been widely used in various channel projects.

[0003] The existing channel forming slipform machines have significant defects in leveling the casting surface, which are concentrated in three aspects: first, the structure of the leveling device is too complicated, which not only pushes up the manufacturing cost, but also makes the maintenance and maintenance of the equipment cumbersome, increases the potential risk of failure, and thus may affect the construction efficiency and progress; second, the adjustment process is not convenient enough, especially when faced with a variety of channel depths and widths, adjusting the leveling device often requires a lot of time and manpower, which increases construction costs and also poses a challenge to the construction progress; third, the leveling effect lacks stability. Due to the interference of factors such as insufficient equipment precision, vibration or impact, the bottom surface of the channel after leveling often becomes uneven, wavy, or even partially convex. These problems will not only reduce the efficiency and life of the channel, but also have a negative impact on its aesthetics and overall quality. Utility Model Content

[0045] Combination Figure 1-Figure 6 As shown, a casting surface leveling device of a forming mold of the utility model comprises a frame 1 for a channel forming slipform machine,

[0046] The support 2 is fixedly mounted on the frame 1 and is integrally formed with the frame 1;

[0047] The outer seat 3 is fixedly mounted on the support 2 and is perpendicular to the bottom surface of the channel, wherein one end of the outer seat 3 close to the bottom surface of the channel is open;

[0048] The movable rod 4 is arranged on the inner side of the outer seat 3 and can be vertically displaced on the inner side of the outer seat 3;

[0049] The leveling member 5 is fixedly mounted on one end of the movable rod 4 close to the bottom surface of the channel and in contact with the bottom surface of the channel, so as to level the bottom surface of the channel;

[0050] The adjusting member 6 is arranged on the outer seat 3 and is interconnected with the movable rod 4. The adjusting member 6 is used to adjust the leveling member 5 to a suitable position according to the channel depth so as to complete the leveling of the concrete construction area on the bottom surface of the channel.

[0051] The core components of the device include a frame 1, which is the basic supporting structure of the entire device. On the frame 1, a support 2 is fixed in an integral manner. This design reduces the connection points between components and enhances the stability of the structure. An outer seat 3 is fixedly installed on the support 2. The outer seat 3 is kept vertically with the bottom surface of the channel, and its end close to the bottom surface of the channel is open to facilitate the flexible movement of the internal components. On the inner side of the outer seat 3, a movable rod 4 is provided. The movable rod 4 can be vertically displaced inside the outer seat 3, so as to achieve the height adjustment of the leveling piece 5. The leveling piece 5 is fixedly installed on the end of the movable rod 4 close to the bottom surface of the channel. When the movable rod 4 moves up and down, the leveling piece 5 will also move accordingly. , in direct contact with the concrete construction site of the bottom of the channel to perform leveling operations. In order to achieve precise adjustment of the height of the leveling piece 5, an adjusting piece 6 is provided in the device. The adjusting piece 6 is installed on the outer seat 3 and is connected to the movable rod 4. By operating the adjusting piece 6, the movable rod 4 can be driven to move vertically in the outer seat 3, and then the leveling piece 5 is adjusted to the optimal position matching the current channel depth to ensure the flatness and construction quality of the concrete on the bottom of the channel. In summary, the forming mold casting surface leveling device achieves precise leveling of the concrete construction site on the bottom of the channel through the coordinated work of the support 2, the outer seat 3, the movable rod 4, the leveling piece 5 and the adjusting piece 6, thereby improving the construction efficiency and quality.

[0052] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 6 As shown; the adjusting member 6 comprises:

[0053] A crank 61 is rotatably disposed on the outer base 3, with one end being disposed on the inner side of the outer base 3 and the other end being disposed on the outer side of the outer base 3;

[0054] The first bevel gear 62 is fixedly mounted on one end of the crank 61 located on the outer seat 3 and can be displaced synchronously with the rotation of the crank 61;

[0055] The transverse plate 63 is fixedly mounted on the inner side of the outer seat 3 and is located between the first bevel gear 62 and the leveling member 5;

[0056] The screw rod 64 is rotatably disposed on the horizontal plate 63, and is perpendicular to the horizontal plate 63;

[0057] The second bevel gear 65 is fixedly mounted on one end of the screw rod 64 and meshes with the first bevel gear 62; and

[0058] The threaded sleeve 66 is embedded in the inner side of the movable rod 4 and is threadedly connected with the screw 64. It can be vertically displaced up and down under the rotation of the crank 61 to adjust the position of the leveling piece 5. The adjusting piece 6 is a key component for realizing the height adjustment of the leveling piece 5. It is composed of a plurality of sub-components that work together. First, the crank 61 is rotatably set on the outer seat 3, one end of which penetrates into the inner side of the outer seat 3, and the other end protrudes from the outer side of the outer seat 3, which is convenient for construction personnel to operate. When the construction personnel rotate the crank 61, the first bevel gear 62 fixedly installed on the inner end thereof will rotate synchronously therewith, the first bevel gear 62 and the second bevel gear 65 are meshed with each other, and the second bevel gear 65 is fixedly installed on one side end of the screw 64, and the screw 64 is rotatably set on the cross plate 63. The cross plate 63 is installed on the inner side of the outer seat 3 as a fixed structure, and is located between the first bevel gear 62 and the leveling piece 5 to support it. And the role of transmitting power, with the rotation of the first bevel gear 62, through the meshing action between the gears, the screw 64 is driven to rotate on the cross plate 63. It is worth noting that the screw 64 and the cross plate 63 are arranged perpendicular to each other, ensuring that the rotational motion can be converted into linear motion. The threaded sleeve 66 is embedded in the inner side of the movable rod 4 and is threadedly connected with the screw 64. When the screw 64 rotates, due to the meshing action of the thread, the threaded sleeve 66 will be vertically displaced along the axial direction of the screw 64. Since the threaded sleeve 66 is fixedly connected to the movable rod 4, the movable rod 4 will also move up and down accordingly. Finally, the vertical displacement of the movable rod 4 will drive the leveling piece 5 to move together, thereby realizing the adjustment of the position of the leveling piece 5. By rotating the crank 61, the construction personnel can easily adjust the leveling piece 5 to the best position matching the current channel depth, thereby ensuring the flatness and construction quality of the concrete on the bottom of the channel.

[0059] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 6As shown; the cross-sections of the outer seat 3 and the movable rod 4 are both rectangular, wherein the outer surface of the movable rod 4 contacts the inner surface of the outer seat 3, and a mounting groove is processed at one end of the movable rod 4 close to the cross plate 63, and a threaded sleeve 66 is connected in the mounting groove by interference fit. The cross-sections of the outer seat 3 and the movable rod 4 are both designed to be rectangular. This design not only enhances the stability of the structure, but also enables the two to maintain good guidance and contact area during relative movement. The movable rod 4 is arranged on the inner side of the outer seat 3, and its outer surface is in close contact with the inner surface of the outer seat 3. This close contact reduces the friction and resistance between the two, so that the vertical displacement of the movable rod 4 in the outer seat 3 is smoother and more stable. Furthermore, a mounting groove is processed at one end of the movable rod 4 close to the cross plate 63, and this mounting groove is specially for the threaded sleeve 66. The threaded sleeve 66 is designed to be connected to the mounting groove by an interference fit, that is, the outer diameter of the threaded sleeve 66 is slightly larger than the inner diameter of the mounting groove. A certain amount of pressure needs to be applied during assembly to make it fully embedded. This connection method not only ensures a firm connection between the threaded sleeve 66 and the movable rod 4, but also avoids loosening or falling off due to vibration or impact during use. When the screw 64 in the adjusting member 6 rotates, since the threaded sleeve 66 and the screw 64 are threadedly connected to each other, the threaded sleeve 66 will be vertically displaced along the axial direction of the screw 64. Since the threaded sleeve 66 is interference fit connected to the mounting groove of the movable rod 4, the movable rod 4 will also move up and down together. This design cleverly utilizes the principles of thread transmission and interference fit to achieve precise adjustment of the position of the leveling member 5.

[0060] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 6 As shown; the flattening member 5 comprises:

[0061] The base 51 is fixedly mounted on one end of the movable rod 4 away from the horizontal plate 63, and can move vertically synchronously with the movement of the movable rod 4;

[0062] The support member 52 is fixedly mounted on one side surface of the base 51, and is perpendicular to the base 51;

[0063] A screed plate 53 is fixedly mounted on the other end of the support member 52, wherein the screed plate 53 is connected to the base 51 through the support member 52; and

[0064] The wear-resistant rubber pad 54 is fixedly mounted on the screed plate 53 and is in contact with the concrete on the bottom of the channel. The screed member 5 is a key component that directly acts on the concrete on the bottom of the channel. Its design fully considers the leveling effect and stability. First, the base 51 is fixedly mounted on the end of the movable rod 4 away from the cross plate 63, which means that when the movable rod 4 is vertically displaced in the outer seat 3, the base 51 can move synchronously with it. This design ensures that the screed member 5 can be accurately adjusted according to the channel depth. The support member 52 is fixedly mounted on one side surface of the base 51 and is arranged perpendicular to the base 51. The main function of the support member 52 is to provide stable support to ensure that the screed plate 53 can maintain a horizontal state during the leveling process to avoid tilting or offset due to external force. The screed plate 53 is fixedly mounted on On the other side end of the support member 52, the support member 52 is connected to the base 51. The screed plate 53 is the part of the screed member 5 that directly contacts the concrete on the bottom of the channel. Its flatness and hardness are crucial to the leveling effect. The design of the screed plate 53 should ensure that it can evenly distribute pressure to avoid local protrusions or depressions during the leveling process. In order to further improve the leveling effect and extend the service life, a wear-resistant rubber pad 54 is fixedly installed on the screed plate 53. The wear-resistant rubber pad 54 has good elasticity and wear resistance, and can effectively reduce the impact of vibration and impact on the concrete on the bottom of the channel during the leveling process, while protecting the screed plate 53 from wear. When the screed member 5 descends and contacts the concrete on the bottom of the channel, the wear-resistant rubber pad 54 first contacts the concrete surface, and achieves smooth leveling operation through its elasticity and wear resistance.

[0065] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 6As shown; a supporting and stabilizing member 7 is also provided between the support 2 and the leveling member 5, which is used to support and fix the leveling member 5 through the supporting and stabilizing member 7. The supporting and stabilizing member 7 is cleverly arranged between the support 2 and the leveling member 5, and its main function is to provide additional support and fixation to the leveling member 5. Specifically, the supporting and stabilizing member 7 may exist in various forms, such as a support rod, a connecting plate or a frame, etc., and its design needs to be reasonably selected according to the specific structure and weight of the leveling member 5. When the leveling device is installed on the channel forming slipform machine and put into use, the leveling member 5 will move with the vertical displacement of the movable rod 4 to achieve the leveling operation of the concrete on the bottom surface of the channel. However, during the leveling process, the leveling member 5 may be subjected to the reaction force from the concrete surface and external factors such as vibration and impact. The influence of factors may cause the leveling piece 5 to shake or deviate, thereby affecting the leveling effect. In order to overcome this problem, a supporting and stabilizing member 7 is introduced and installed between the support 2 and the leveling piece 5. One end of the supporting and stabilizing member 7 is connected to the support 2, and the other end is connected to a stable part of the leveling piece 5, such as the base 51 or the supporting member 52. In this way, the supporting and stabilizing member 7 provides an additional supporting point for the leveling piece 5, increasing its stability during operation. At the same time, the supporting and stabilizing member 7 also has a certain fixing effect, which can firmly connect the leveling piece 5 to the support 2 to prevent the leveling piece 5 from unnecessary displacement or loosening during the leveling process. This fixing effect not only improves the stability of the leveling piece, but also ensures the accuracy of the leveling precision.

[0066] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 6 As shown; the supporting and stabilizing member 7 comprises:

[0067] The vertical connecting member 71 is fixedly mounted on the base 51 and is perpendicular to the base 51. There are two vertical connecting members 71, which are respectively distributed on both sides of the movable rod 4.

[0068] A hinged seat 72 is fixedly mounted on a side surface of the support 2 close to the bottom surface of the channel; and

[0069] The diagonal brace connector 73 is hinged on the hinge seat 72, and can be rotated and displaced according to the hinge seat 72 as the origin, wherein the number and distribution position of the diagonal brace connector 73 are adapted to the vertical connector 71, and the diagonal brace connector 73 is connected to the vertical connector 71. The support and stabilization member 7 is a key component for enhancing the stability of the leveling member 5, and is mainly composed of three parts: the vertical connector 71, the hinge seat 72 and the diagonal brace connector 73. First, the vertical connector 71 is fixedly installed on the base 51 and is in a relative position to the base 51. The vertical connection members 71 are arranged perpendicular to each other. This design enables the vertical connection member 71 to stably support part of the weight of the leveling member 5 and provide it with a stable support point in the vertical direction. It is worth noting that there are two vertical connection members 71, which are distributed on both sides of the movable rod 4. This layout helps to disperse the force and improve the overall stability of the leveling member 5. Next, the hinge seat 72 is fixedly installed on the side surface of the support 2 close to the bottom surface of the channel. The hinge seat 72 serves as the rotation fulcrum of the diagonal support connection member 73, and its design needs to ensure The diagonal brace connector 73 can withstand the force and torque generated during the rotation process. The diagonal brace connector 73 is hinged on the hinge seat 72, and can be rotated and displaced according to the hinge seat 72 as the origin. This design enables the diagonal brace connector 73 to adjust its inclination angle and length according to actual needs to adapt to different working conditions and channel depths. At the same time, the number and distribution position of the diagonal brace connector 73 are adapted to the vertical connector 71 to ensure that the two can be tightly connected and jointly bear the weight and force of the leveling member 5. During the working process, when the leveling member 5 moves with the vertical displacement of the movable rod 4, the supporting and stabilizing member 7 begins to play a role. The vertical connector 71 first provides a stable support in the vertical direction for the leveling member 5, and the diagonal brace connector 73 provides an oblique supporting force for the leveling member 5 through its rotational displacement and connection with the vertical connector 71. This oblique supporting force can effectively resist the reaction force from the concrete on the bottom of the channel and the influence of external vibration, impact and other factors, ensuring that the leveling member 5 always remains stable during the working process.

[0070] In a preferred embodiment, the present invention can be further configured as follows: Figures 1 to 6As shown; a first connecting hole is processed on the surface of the vertical connecting member 71, and a second connecting hole is processed on the surface of the diagonal brace connecting member 73, wherein a connecting pin placed on the inner side of the second connecting hole is arranged on the inner side of the first connecting hole, and the cross-section of the connecting pin is set in an I-shape. In the design of the supporting and stabilizing member 7, the vertical connecting member 71 serves as a key component connecting the leveling member 5 and the diagonal brace connecting member 73, and a first connecting hole is processed on its surface. The positions and numbers of these first connecting holes are carefully arranged according to design requirements to ensure accurate docking with the diagonal brace connecting member 73. At the same time, second connecting holes corresponding to the first connecting holes are also processed on the surface of the diagonal brace connecting member 73, and the inner diameters and depths of these second connecting holes match the first connecting holes, providing a basis for the subsequent installation of the connecting pins. It is worth noting that the dependent claim specifically points out that the cross-section of the connecting pin is set in an I-shape. This special shape design enables the connecting pin to form a more stable connection structure after being inserted into the first connecting hole and the second connecting hole. The I-shaped cross-section not only increases the size of the connecting pin The contact area between the vertical connector 71 and the connecting hole improves the strength and stability of the connection, and also makes the connecting pin less likely to slide or fall off when subjected to external force. In actual working process, when it is necessary to install the supporting and stabilizing member 7, first fix the vertical connector 71 on the base 51, and then hinge one end of the diagonal support connector 73 on the hinge seat 72. Next, pass the connecting pin through the first connecting hole and the second connecting hole in turn until it is fully inserted and fixed on the inner side of the connecting hole. Since the cross-section of the connecting pin is I-shaped, it can be tightly engaged in the connecting hole to form a reliable connection. Through this connection method, a stable supporting structure is established between the vertical connector 71 and the diagonal support connector 73. This structure can not only withstand the weight and force from the leveling member 5, but also effectively resist the influence of external vibration, impact and other factors, ensuring that the leveling member 5 always remains stable during operation. At the same time, the design of the I-shaped connecting pin also improves the reliability and durability of the connection, and extends the service life of the supporting and stabilizing member 7.

[0071] The specific working principle of the utility model of a forming mold casting surface leveling device is as follows:

By rotating the crank 61, the first bevel gear 62 is driven to rotate, and then the second bevel gear 65 and the screw 64 engaged therewith are driven to rotate. Since the threaded sleeve 66 is threadedly connected with the screw 64 and is embedded in the inner side of the movable rod 4, the screw 64 The rotation of the threaded sleeve 66 and the movable rod 4 will cause the threaded sleeve 66 and the movable rod 4 to move vertically up and down, thereby realizing the precise adjustment of the position of the leveling member 5. In addition, in order to improve the stability of the leveling member 5 during operation, the device is also provided with a supporting and stabilizing member 7, which is composed of a vertical connecting member 71, a hinge seat 72 and a diagonal support connecting member 73. The vertical connecting member 71 is fixedly installed on the base 51 and is vertically arranged with the base 51. There are two of them, which are respectively located on both sides of the movable rod 4. The hinge seat 72 is fixed to the side of the support 2 close to the bottom surface of the channel. The diagonal support connecting member 73 is hinged to the hinge seat 72. , can rotate around the hinge seat 72, its number and position are adapted to the vertical connecting piece 71, and it is connected to the vertical connecting piece 71 through a connecting pin. The cross-section of the connecting pin is I-shaped, which ensures the stability of the connection. When working, the operator first adjusts the leveling piece 5 to a suitable position through the adjusting piece 6 according to the channel depth. Then, the leveling device moves with the channel forming slipform machine. The leveling piece 5 levels the concrete on the bottom surface of the channel under the action of the wear-resistant rubber pad 54.
