Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of retaining wall processing, in particular to a multi-stage assembled cantilever retaining wall processing device based on cement stone. BACKGROUND

[0002] The multi-stage assembled cantilever retaining wall represents an advanced concept of modern retaining structure, which ingeniously combines the classic cantilever retaining wall mechanics principle with the leading prefabricated assembly construction technology. The core of this structure form is that it decomposes the traditional large wall body that needs a large amount of site pouring concrete into a series of standardized prefabricated units that can be produced in a factory. These units usually use high-strength and durable reinforced concrete, which are pre-made under strict quality control environment, then transported to the project site, and assembled step by step like connecting precise components. Its construction process significantly reduces the uncertainty caused by site wet work, not only greatly shortens the construction period and reduces the interference to the surrounding environment, but also is especially suitable for major projects with narrow construction site, tight construction period or high environmental protection requirements, so it shows significant technical and economic advantages in high slope support in the fields of highway subgrade high fill, railway station slope, municipal landscape slope protection, etc.

[0003] In the existing prefabrication process of retaining wall components, the uniformly mixed cement concrete is usually poured into the prefabricated processing mold, and the shaping effect of the mold is relied on to make it solidify and form. However, due to the cohesive and air-containing properties of cement, and the inevitable air entrainment in the mixing, conveying and pouring process, a small amount of air bubbles or local impurities are left in the mixture. If these gases cannot be effectively discharged during the vibration or curing stage, they will remain in the concrete and gradually form fine cavities or local looseness. When the component is demolded and reaches the curing strength, these internal defects will not disappear automatically, but become weak links in the structure, thereby reducing the density and uniformity of the material, and ultimately adversely affecting the overall quality and long-term safety of the component.

[0004] In view of this, we propose a multi-stage assembled cantilever retaining wall processing device based on cement stone. SUMMARY

[0005] The cement stone-based multi-stage assembled cantilever retaining wall processing device is characterized in that the device comprises a processing seat, a C-shaped protective frame is fixedly connected to the top of the processing seat, a telescopic cylinder is fixedly connected to the top of the C-shaped protective frame, the bottom end of the telescopic rod of the telescopic cylinder penetrates through the bottom of the horizontal plate of the C-shaped protective frame and is fixedly connected with an extrusion mechanism used for processing the retaining wall, a placing groove is formed in the top of the processing seat, and a lower mold frame is slidably connected in the placing groove.

[0006] Preferably, the extrusion mechanism comprises a connecting plate, the top of the connecting plate is fixedly connected with the bottom end of the telescopic rod of the telescopic cylinder, T-shaped grooves are formed in the left and right sides of the top of the connecting plate, two T-shaped plates are slidably connected in the T-shaped grooves, four first compression springs are fixedly connected to the bottom of the horizontal plate of each T-shaped plate, and the bottom end of each first compression spring is fixedly connected with the bottom of the inner wall of the horizontal groove of the T-shaped groove. Through the elastic action of the first compression springs, the T-shaped plates are provided with effective buffering and automatic resetting functions, the impact and vibration generated during the operation of the mechanism are significantly absorbed, the stability and continuity of the movement of the T-shaped plates and related components are ensured, and the service life of the entire extrusion mechanism is also prolonged.

[0007] Preferably, an L-shaped groove is formed in the middle of the inner wall of each T-shaped plate, an L-shaped plate is slidably connected in the L-shaped groove, a second compression spring is fixedly connected to the side surface of the vertical plate of the L-shaped plate, and one end of the second compression spring is fixedly connected with the side surface of the vertical groove of the L-shaped groove. By simultaneously extruding the two L-shaped plates to the middle, the second compression springs can be compressed, the horizontal plates of the L-shaped plates are withdrawn from the inside of the mounting grooves, the operator can quickly release the fixed state between the upper mold plate and the connecting plate, the process of replacing or maintaining the upper mold plate is greatly simplified, and the operation convenience and overall working efficiency are improved.

[0008] Preferably, the bottom of the connecting plate is provided with an upper mold plate, the top of the upper mold plate is provided with two installation grooves, the inside of the installation grooves is in sliding fit with the inside of the L-shaped plate, and the shape of the inner wall of the installation groove is L-shaped. By moving the L-shaped plate to the inside of the installation groove, the upper mold plate can be firmly locked below the connecting plate, ensuring that the upper mold plate can still maintain extremely high connection rigidity and stability when bearing high-strength and high-frequency extrusion forces, effectively preventing product quality problems that may be caused by displacement or loosening during processing.

[0009] Preferably, the left and right sides of the top of the connecting plate are fixedly connected with two limiting frames, the connecting rods are rotatably connected in the limiting frames, and the two connecting rods in each group are fixedly connected with a resisting strip on the opposite side. The resisting strip can contact and resist the top of the T-shaped plate, so as to push the T-shaped plate to move downward. By effectively converting the rotary motion into linear motion, the accuracy and reliability of mechanism action transmission are ensured.

[0010] Preferably, the resisting strip comprises a rotating frame, one end of the connecting rod is fixedly connected with the side surface of the rotating frame, a T-shaped strip is slidably connected in the rotating frame, the side surface of the vertical bar of the T-shaped strip is rounded and abuts against the top of the horizontal plate of the T-shaped plate, a fourth compression spring is fixedly connected with the side surface of the horizontal bar of the T-shaped strip, and one end of the fourth compression spring is fixedly connected with the inside of the rotating frame. The side surface of the vertical bar of the T-shaped strip is rounded, so that it can smoothly contact the top of the horizontal plate of the T-shaped plate. When the rotating frame rotates, the T-shaped strip rotates synchronously, a continuous and uniform vertical downward pressure is applied to the T-shaped plate, the fourth compression spring constitutes an inherent buffer system, which ensures the flexibility when the T-shaped strip initially contacts the T-shaped plate, and maintains the stability of the force during the entire pressing process, effectively eliminating the impact, noise and component wear caused by rigid contact.

[0011] Preferably, the side surface of the connecting rod is fixedly sleeved with a gear, two vertical plates of the C-shaped protective frame are provided with two long grooves on the opposite sides, the inside of the long grooves is fixedly connected with a rack, and the side surface of the rack is engaged with the gear. By cooperating the gear with the rack, the linear motion of the protective frame in the direction is converted into the rotary motion of the connecting rod, the input of the external power source can be converted into the predetermined rotary motion of the connecting rod and the terminal resisting strip, and the accuracy and coordination of the motion trajectory and timing of the entire system are ensured.

[0012] Preferably, the top of the processing seat is fixedly connected with four limiting rods, the top of the limiting rods penetrates through the top of the connecting plate and is fixedly connected with the bottom of the horizontal plate of the C-shaped protective frame, the side of the limiting rods movably sleeves the moving block, the outer side of the moving block is fixedly connected with the inner side of the connecting plate, the moving block reduces the friction force generated when the connecting plate slides on the side of the limiting rods, the moving block arranged between the connecting plate and the limiting rods greatly reduces the friction resistance between the connecting plate and the limiting rods during the reciprocating movement of the connecting plate, not only makes the operation more stable and smooth, but also effectively reduces the wear of the parts, the four limiting rods jointly form a rigid guide frame, strictly restricts the connecting plate to move only in the vertical direction, completely avoids the inclination or deflection of the connecting plate during the extrusion process, ensures that the upper die plate and the lower die frame are always accurately aligned, thereby ensuring the accuracy of the forming size and the clarity of the profile of the retaining wall component, and providing a key guarantee for batch production of high-quality standard components.

[0013] Compared with the prior art, the beneficial effects of the present application are:

[0014] In the present application, by pouring cement into the lower die frame, the connecting plate and the upper die plate are driven downward by the telescopic cylinder, and the limiting frame, the connecting rod and the gear are also driven downward, so that the gear drives the connecting rod and the abutting bar to rotate through the rack, and when the abutting bar drives the T-shaped bar to rotate and abut against the top of the horizontal plate of the T-shaped plate, the T-shaped plate is extruded downward, the first compression spring is compressed, and the upper die plate is vibrated, so that the upper die plate continuously vibrates up and down when it moves downward, the small amount of bubbles in the cement is quickly broken, the material density is increased, and the quality of the retaining wall structure during long-term use is ensured.

[0015] By moving the two L-shaped plates towards the middle at the same time, the second compression spring is compressed, the fixing of the upper die plate is released, the upper die plate with a suitable shape can be replaced, and the installation groove is aligned with the L-shaped plate, after the upper die plate and the bottom of the connecting plate are attached, the L-shaped plate is loosened, the L-shaped plate is reset through the second compression spring, at this time the replaced upper die plate can be quickly fixed, and different upper die plates can be quickly replaced to process the structure of the retaining wall at different positions.

[0016] When the connecting plate drives the upper die plate to move downward to extrude the cement into a retaining wall, the T-shaped bar is rotated by the rotating frame, the vertical bar of the T-shaped bar extrudes the top of the T-shaped plate, the T-shaped plate drives the upper die plate at the bottom to move downward, the first compression spring is compressed, at the same time, the T-shaped bar moves into the rotating frame under the abutting force and compresses the fourth compression spring, when the rotating frame drives the T-shaped bar to rotate to release the contact with the T-shaped plate, the T-shaped bar is reset through the fourth compression spring, at the same time, the T-shaped plate is reset upward through the rebound force of the first compression spring, and the upper die plate, thereby increasing the overall thickness of the cement inside the retaining wall, reducing the existence of gaps inside the retaining wall, and increasing the service life of the retaining wall.
