Description

Technical Field

[0001] The present application relates to the technical field of slipform pavers, and in particular to a mold lifting device for slipform pavers. Background Art

[0002] In road construction, slipform pavers are often used to lay moisture-proof, waterproof, and anti-corrosion materials on the road surface. They are also used for side paving of concrete structures such as curbs, gutters, channels, drains, and cable troughs.

[0003] In the prior art, a special slipform mold is required for the operation of the slipform paver. Figure 5 As shown, when designing a slipform mold, the mold's mounting plane is typically parallel to the top of the structure and connected to the bottom bracket of the slipform paver using four bolts. The mold and bracket are fixed in position and cannot vary in height. This method can meet construction, technical, and mold stress requirements when paving smaller structures.

[0004] However, when paving large structures such as ditches and bridge guardrails, the structures are typically 1-1.5 meters high and contain internal reinforcement cages. After the slipform construction is complete, the molds must be cleaned and the concrete adhering to the inner walls removed. For long work surfaces, this cannot be completed on the same day. Furthermore, after the construction is completed, the maximum lift limit of the slipform paver's legs is only 1.1 meters. Even when the legs are raised to their highest point, the mold cannot be lifted upward from the reinforcement cage at the construction site.

[0005] The current conventional method involves moving the slipform paver to the front of the work surface, disengaging from the reinforcement cage, and then cleaning the mold. Before the next day's construction, the slipform paver must reverse the mold from the front of the work surface into the reinforcement cage, then back to the previous day's breakpoint before paving can resume. This method consumes a significant amount of the slipform paver's operating time, significantly reducing construction efficiency.

[0006] Therefore, there is an urgent need for a slipform paver mold lifting device to solve the above problems. Utility Model Content

[0036] Combine Figure 1-Figure 4 As shown, a slipform paver mold lifting device includes a bracket 1, a connecting frame 10, a movable sleeve 12, a lifting member 13 and a connecting plate 14; the bracket 1 is horizontally fixedly arranged on the side of the hopper 3; the connecting frame 10 is fixedly arranged at one end of the bracket 1 close to the hopper 3, and a guide frame 11 is vertically arranged on the side of the connecting frame 10 close to the hopper 3; the movable sleeve 12 is slidably arranged on the periphery of the guide frame 11; the lifting member 13 is vertically arranged between the connecting frame 10 and the movable sleeve 12, the fixed end of the lifting member 13 is fixedly connected to the top of the guide frame 11, and the movable end is fixedly connected to the bottom of the movable sleeve 12; the connecting plate 14 is fixedly arranged on the side of the movable sleeve 12 away from the lifting member 13, the plate surface of the connecting plate 14 is always perpendicular to the ground, and the side thereof away from the lifting member 13 is fixedly connected to the mold 2.

[0037] In the above scheme, the bracket 1 is fixed horizontally to the side of the hopper 3, serving as the support base of the entire lifting device. The connecting frame 10 is fixed to the end of the bracket 1 near the hopper 3, and a guide frame 11 is vertically arranged on it, providing a sliding track for the movable sleeve 12. The movable sleeve 12 is slidably arranged on the periphery of the guide frame 11 and is driven to move up and down on the guide frame 11 by the extension and contraction of the lifting member 13. The connecting plate 14 is fixed to the side of the movable sleeve 12 away from the lifting member 13 and is fixedly connected to the mold 2, ensuring that the mold 2 can be lifted up and down as the movable sleeve 12 moves.

[0038] When mold 2 needs to be lifted (for cleaning or paving a high structure), the movable end of lifting member 13 begins to retract, pushing movable sleeve 12 upward along guide frame 11. Pulled by lifting member 13, movable sleeve 12 lifts connecting plate 14 and mold 2 secured thereto. Because connecting plate 14 remains perpendicular to the ground, mold 2 remains stable during the lifting process, preventing tilting or shaking.

[0039] When the mold 2 needs to be lowered, the movable end of the lifting member 13 begins to extend, and the movable sleeve 12 moves downward along the guide frame 11 under the push of the lifting member 13. The movable sleeve 12 drives the connecting plate 14 and the mold 2 fixed thereon to descend together until they reach the desired position.

[0040] In this application, the mold 2 can be quickly raised and lowered by the lifting member 13, ensuring that the mold 2 can be easily extracted and replaced from the steel cage even when the paving height is limited. The surface of the connecting plate 14 is always perpendicular to the ground, ensuring that the mold 2 remains stable during the lifting process, preventing the mold 2 from tilting or shaking and causing secondary construction, thereby improving construction efficiency.

[0041] Two vertical sides of the connecting plate 14 close to the lifting member 13 are provided with C-shaped flanges 141 , and the flanges 141 are clamped to the C-shaped structure of the vertical portion of the moving sleeve 12 .

[0042] In the above solution, the C-shaped structure formed by connecting plate 14 tightly wraps around the vertical portion of movable sleeve 12, increasing the contact area between connecting plate 14 and movable sleeve 12, and improving the stability and strength of the connection between them. When lifting member 13 drives movable sleeve 12 up and down, the C-shaped connecting plate 14 effectively prevents movable sleeve 12 from shaking or shifting in the vertical direction, ensuring that mold 2 can be smoothly raised and lowered.

[0043] The connecting frame 10 is a square frame structure as a whole, and its bottom is fixedly connected to the upper end surface of the bracket 1. Reinforcing ribs 15 are provided on the inner circumference. One end of the reinforcing rib 15 is fixedly connected to the top of the connecting frame 10, and the other end is fixedly connected to the bottom of the connecting frame 10. The length direction of the reinforcing rib 15 is set at an angle to the length direction of the connecting frame 10.

[0044] In the above solution, the square frame structure of the connecting frame 10 enables the connecting frame 10 to maintain good stability and rigidity when bearing the gravity from the mold 2 and the lifting member 13, as well as various forces from the external environment. One end of the reinforcing rib 15 is fixedly connected to the top of the connecting frame 10, and the other end is fixedly connected to the bottom of the connecting frame 10, forming a stable triangular support structure to prevent the connecting frame 10 from deformation or damage. In addition, the rib length direction of the reinforcing rib 15 is set at an angle to the frame length direction of the connecting frame 10, which can enable the reinforcing rib 15 to better disperse and transmit the force from the mold 2 and the lifting member 13, thereby improving the load-bearing capacity of the connecting frame 10.

[0045] The side surface of the guide frame 11 of the Chinese-Symbol-shaped structure close to the lifting member 13 is detachably connected to the connecting frame 10 in an integral manner to form an L-shaped frame structure.

[0046] In the above scheme, the spherical "S"-shaped guide frame 11 effectively resists the forces from the movable sleeve 12 and the lifting member 13, while also providing a clear sliding track for the movable sleeve 12, ensuring the accuracy and stability of the movable sleeve 12 during the lifting process. The L-shaped frame structure formed by the integrally detachable connection between the guide frame 11 and the connecting frame 10 not only enhances the stability of the entire lifting device, but also allows the guide frame 11 to be more firmly fixed to the connecting frame 10, making it less likely to loosen or fall off.

[0047] An adjustment assembly is fixedly arranged between the connecting frame 10 and the bracket 1; wherein the adjustment assembly includes a support plate 16, a stud 17, a connecting pipe 18, and a bolt 19; the support plate 16 is fixedly arranged at the bottom of the connecting frame 10; a plurality of studs 17 are respectively arranged at the bottom of the support plate 16, one end of which is fixedly connected to the bottom of the support plate 16, and the other end is vertically downward and spaced from the upper end surface of the bracket 1; the connecting pipe 18 is vertically fixed between the support plate 16 and the bracket 1, and is sleeved on the periphery of the stud 17; the bolt 19 passes horizontally through the wall of the connecting pipe 18 and engages with the peripheral surface of the stud 17.

[0048] In the above solution, the support plate 16 is fixedly arranged at the bottom of the connecting frame 10, serving as the support base of the adjustment assembly. The stud 17 provides vertical adjustment space for the adjustment assembly, and the connecting tube 18 provides a guide for the up and down movement of the stud 17. When it is necessary to adjust the height between the connecting frame 10 and the bracket 1, the operator first loosens the bolt 19 on the connecting tube 18, and then drives the stud 17 up and down in the connecting tube 18 by rotating the bolt 19 (or using a special tool). Since the fit between the stud 17 and the connecting tube 18 is tight, the movement of the stud 17 will drive the support plate 16 and the connecting frame 10 to move up and down together. When the desired height is reached, stop turning the bolt 19.

[0049] In the above solution, the arrangement of the adjustment assembly allows for adjustable height between the connecting frame 10 and the bracket 1, thereby adapting to different construction environments and requirements. For example, at varying ground heights or for different mold 2 sizes, the adjustment assembly can be used to adjust the height of the lifting device a second time, ensuring smooth lifting and lowering of the mold 2, thereby reducing waiting time and adjustment time during construction.

[0050] A backing plate 20 is provided on the end face of the connecting plate 14 away from the lifting member 13 . One side of the backing plate 20 is fixedly connected to the corresponding plate surface of the connecting plate 14 , and the opposite side thereof is fixedly connected to the outer wall of the mold 2 .

[0051] In the above scheme, when the lifting member 13 drives the connecting plate 14 to move up and down, the connecting plate 14 transmits force to the mold 2 through the pad 20, avoiding the stress concentration phenomenon caused by the direct contact between the connecting plate 14 and the mold 2. The pad 20 serves as a buffer layer between the connecting plate 14 and the mold 2, which can effectively reduce the impact and vibration of the mold 2 during the lifting process, thereby extending the service life of the mold 2 and reducing the maintenance and replacement costs.

[0052] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0053] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
