Track mechanism for a ramp paver

Abstract

This utility model relates to a track mechanism for a slope paver, including a left track mechanism and a right track mechanism erected between a retaining wall and a wave-breaking wall. Both the left and right track mechanisms have outer and inner tracks, respectively supporting the longitudinal movement of the main paving mechanism and the auxiliary paving mechanism. The upper frame is hinged to the beam via an upper adjustable angle structure, and the rear end of the beam is connected to the rear lateral beam via a lower adjustable angle structure. An arc-shaped groove and a pin shaft cooperate to achieve stepless adjustment of the beam's tilt angle, adapting to slopes of 5°–45°. The front and rear lateral motors synchronously drive the upper and lower traveling wheels, causing the track mechanism to move laterally along the wave-breaking wall and the retaining wall. Limiting wheels are pressed tightly against the front side of the wave-breaking wall via positioning rods to prevent the track mechanism from detaching. This utility model provides a track foundation for the mechanized paving mechanism of a slope paver, reducing reliance on manual labor, significantly improving paving efficiency, and allowing for convenient lateral movement to the next construction slope section.

Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to the paving technology of interlocking concrete blocks in slope protection engineering. Background Technology

[0002] Interlocking concrete blocks are highly durable and resistant to environmental erosion. Designed with an interlocking structure, they can be installed quickly and are generally more cost-effective than other building materials.

[0003] In the field of water conservancy engineering, concrete interlocking blocks are widely used in various slope protection projects, such as river slope protection and dam slope protection, and are also frequently used in lake and reservoir bank protection projects.

[0004] Interlocking concrete blocks are well-suited for various slope protection projects in hydraulic engineering due to their interlocking structure. The applicant has used interlocking concrete blocks for slope protection on multiple construction sites. Because the interlocking concrete blocks are interlocked, the scouring effect of water flow cannot disturb any single interlocking concrete block individually, thus significantly increasing the stability of the slope protection.

[0005] Laying concrete interlocking blocks on the slope is an essential step. Currently, the concrete interlocking blocks are typically modified from simple curb clamps and transported using wire ropes and a crane. This method requires frequent manual unloading and reloading throughout the entire process, which is not only labor-intensive but also poses significant safety hazards; operational errors can easily lead to accidents.

[0006] In addition, for some large-volume and heavy concrete interlocking blocks, it is difficult for people to stand and walk when they are manually moved on the slope. Multiple people are required to work together, which not only makes the moving difficult and the work inefficient, but also increases the project cost.

[0007] With the continuous expansion of engineering construction scale and the increasing demands for construction efficiency and safety, it has become necessary to develop a new type of mechanized paver.

[0008] Mechanized pavers require a track mechanism to support the paving mechanism as it moves up and down the slope. The research and development concept of this utility model is as follows: Slopes in hydraulic engineering projects often have toe walls and wave-breaking walls. Utilizing these as support and guiding structures for the track mechanism, a track mechanism connecting the two is designed for the slope paver to move up and down the slope under the support and guidance of the track mechanism. Utility Model Content

[0009] The purpose of this utility model is to provide a track mechanism for a slope paver, which provides structural support for the slope paver to move up and down along the slope under the support and guidance of the track mechanism and to facilitate the overall lateral movement.

[0010] To achieve the above objectives, the track mechanism of a slope paver of the present invention includes a left track mechanism and a right track mechanism erected between the toe wall and the wave wall. Both the left track mechanism and the right track mechanism include a beam with a frame structure. An outer track is connected to the outer side of the upper end of the beam. The outer track extends along the beam and serves to support and guide the rollers of the main paving mechanism of the slope paver.

[0011] The front end of the beam is connected to an upper bracket, and the upper bracket is fixedly connected to a front transverse beam. The bottom of the front transverse beam is equipped with an upper traveling wheel, which is supported on the wave-breaking wall. The front transverse beam is equipped with a front transverse motor, which drives the upper traveling wheel to move the upper bracket laterally.

[0012] The rear end of the beam is connected to a rear transverse beam via a lower adjustable angle structure. The bottom of the rear transverse beam is equipped with a lower traveling wheel, which is supported on the foot protection wall. The rear transverse beam is equipped with a rear transverse motor to drive the lower traveling wheel to move laterally.

[0013] The upper bracket is connected to the beam via an upper adjustable angle structure. The lower adjustable angle structure and the upper adjustable angle structure allow the beam to rotate to adapt to different slopes.

[0014] An inner track is connected to the beam inside the outer track, and the inner track is set parallel to and spaced apart from the outer track; the inner track is used to support and guide the rollers of the auxiliary paving mechanism of the slope paver.

[0015] The upper bracket is equipped with a limit wheel and a positioning rod between itself and the wave-breaking wall. The limit wheel presses tightly against the front side of the wave-breaking wall to prevent the track mechanism from detaching.

[0016] The adjustable angle structure includes a connecting frame, a front lower hinge shaft, a front arc plate, and a front upper pin shaft;

[0017] The bottom end of the connecting frame is hinged to the bottom of the front end of the beam through the lower front hinge shaft. The front arc plate is fixed on the connecting frame and has a front arc groove. The upper front pin passes through the pin hole and the front arc groove of the beam. The front arc groove serves as a guide and support structure for the upper front pin.

[0018] The adjustable angle structure includes a rear upper hinge shaft, a rear arc plate, and a rear lower pin shaft;

[0019] The rear end of the beam is hinged to the rear transverse beam via the rear upper hinge shaft. The rear arc plate is fixed to the rear transverse beam and has a rear arc groove. The rear lower pin passes through the pin hole and the rear arc groove of the beam.

[0020] Both the upper front pin and the lower rear pin are threaded shafts, and both ends of the threaded shafts are connected to clamping nuts.

[0021] The limiting wheel is installed on the front side of the upper bracket via a positioning rod, and the limiting wheel makes rolling contact with the front side of the wave-breaking wall.

[0022] The front and rear transverse motors are driven synchronously, enabling the track mechanism to move laterally along the wave-breaking wall and the foot wall.

[0023] The track mechanism and outer track provide a structural foundation for the main paving mechanism of the slope paver to move back and forth along the track mechanism. The upper and lower adjustable angle structures enable this utility model to achieve slope self-adaptation. The traveling wheels ensure stability, and the adjustable angle structure improves construction adaptability, making it easy to use on slope sections with different slopes.

[0024] The inner and outer tracks provide structural support for the operation of the main paving mechanism and the auxiliary paving mechanism of the slope paver.

[0025] The limit wheels prevent the upper frame from detaching from the wave-breaking wall under the overall gravity of the track mechanism, without affecting the lateral movement of the upper frame.

[0026] The hinged joints and curved grooves enable flexible adjustment. The double-hinged design at both ends of the beam enhances slope adaptability, while the curved grooves provide angle adjustment margins. The simple upper and lower adjustable angle structures allow the beam to be supported and rotated between the upper bracket (connecting frame) and the rear transverse beam, accommodating construction needs on slopes with varying gradients and solving the problem of existing equipment's inability to adapt to slopes. After placing the device on the slope, tightening the clamping nut fixes the beam's tilt angle, ensuring construction stability. The connection structure of the limiting wheels is simple and easy to manufacture.

[0027] This utility model and its supporting slope paving machine have been practically applied in the Baiguishan Reservoir slope reinforcement and protection project. At the beginning of the Baiguishan Reservoir slope reinforcement and protection project in Henan Province, the traditional precast interlocking block paving process mainly relied on a combination of crane lifting and manual handling. Given the problems of low efficiency, high cost, and significant safety hazards associated with the traditional operation mode, the project's R&D team successfully developed a new type of intelligent construction equipment integrating automatic material handling, precise stacking, and efficient paving functions. This equipment, through the establishment of a complete automated operation system, has demonstrated the following core technical features in engineering practice:

[0028] I. Overall Innovative Structural Design and Functional Implementation:

[0029] This equipment innovatively adopts a dual support structure of retaining walls and wave-breaking walls as the motion carrier, realizing coordinated operation of lateral movement and continuous paving. Its core structure includes an adjustable angle adaptation mechanism, which can accurately adapt to slope gradient changes of 5°-45° (inclusive of the two extremes) and completely eliminate personal safety hazards such as falling objects from heights and heavy object handling.

[0030] II. Automated Slope Adaptation System

[0031] With its adjustable upper and lower angle structures, this invention can automatically match different slope gradients. Field tests show that the terrain adaptation time is reduced from 2.5 hours / 100㎡ in the traditional process to 1.2 hours / 100㎡, and the planar positioning accuracy reaches ±2mm / ㎡, significantly improving the construction quality stability and construction efficiency under special working conditions of water conservancy projects.

[0032] III. Comprehensive Benefit Analysis of the Project

[0033] In large-scale revetment projects, this equipment demonstrates significant advantages in large-scale construction.

[0034] Work efficiency indicators: Continuous paving speed reaches 25-30 m² / h, which is 2-3 times faster than traditional methods. Cost control: Overall construction cost is reduced by 42%, with labor cost savings accounting for 68%.

[0035] Quality assurance: The first-pass yield rate of interlocking block joints has increased from 83% to 98.5%.

[0036] Safety performance: Achieve 100% mechanization of high-risk operations.

[0037] The successful application of this equipment and the entire slope paver marks a new stage of mechanization in the construction of slope protection in water conservancy projects. Its modular design concept provides a replicable technical paradigm for similar projects and has significant industry promotion value. Attached Figure Description

[0044] In this invention, "forward" refers to the direction from the bottom of the slope to the top of the slope, and "leftward" refers to the left side when facing forward.

[0045] Before implementing this utility model, if the slope lacks a foot protection wall 1 or a wave-breaking wall 2, the foot protection wall 1 or wave-breaking wall 2 should be constructed and improved at the bottom and top of the slope respectively.

[0046] like Figures 1 to 6 As shown, this utility model discloses a track mechanism for a slope paver, including a left track mechanism and a right track mechanism erected between a toe wall 1 and a wave-breaking wall 2. Both the left track mechanism and the right track mechanism include a beam 4 with a frame structure. An outer track 5 is connected to the outer side of the upper end of the beam 4. In the left-right direction, the direction away from the other track mechanism is outward. The outer track 5 extends along the beam 4 and serves to support and guide the rollers of the main paving mechanism of the slope paver.

[0047] The beam 4 is connected to an upper bracket 7 at its front end. The upper bracket 7 is fixedly connected to a front transverse beam 8 at its lower end. The bottom of the front transverse beam 8 is equipped with an upper traveling wheel 9, which is supported on the wave-breaking wall 2. The front transverse beam 8 is equipped with a front transverse motor 10, which drives the upper traveling wheel 9 to move the upper bracket 7 laterally.

[0048] The rear end of the beam 4 is connected to a rear transverse beam 14 via a lower adjustable angle structure. The bottom of the rear transverse beam 14 is equipped with a lower traveling wheel 16, which is supported on the foot protection wall 1. The rear transverse beam 14 is equipped with a rear transverse motor 15 to drive the lower traveling wheel 16 to move laterally.

[0049] The upper bracket 7 is connected to the beam 4 via an upper adjustable angle structure. The lower adjustable angle structure and the upper adjustable angle structure allow the beam 4 to rotate to adapt to different slopes.

[0050] The transmission mechanism between the rear traverse motor 15 and the lower traveling wheel 16, and the transmission mechanism between the front traverse motor 10 and the upper traveling wheel 9, can all be belt drive mechanisms, chain drive mechanisms, or gear drive mechanisms. These are all conventional technologies and will not be described in detail.

[0051] The track mechanism and outer track 5 provide a structural foundation for the main paving mechanism of the slope paver to move back and forth along the track mechanism. The upper and lower adjustable angle structures enable this utility model to achieve slope self-adaptation. The traveling wheels ensure stability, and the adjustable angle structure improves construction adaptability, making it easy to use on slope sections with different slopes.

[0052] An inner track 6 is connected to the beam 4 inside the outer track 5. The inner track 6 is set parallel to and spaced apart from the outer track 5. The inner track 6 is used to support and guide the rollers of the auxiliary paving mechanism of the slope paver.

[0053] The ramp paver has a main paving mechanism and an auxiliary paving mechanism. The outer track 5 corresponds to the main paving mechanism, and the inner track 6 corresponds to the auxiliary paving mechanism, providing a basis for batch paving (concrete interlocking blocks) using the main paving mechanism and paving single concrete interlocking blocks using the auxiliary paving mechanism.

[0054] A limiting wheel 12 and a positioning rod 11 are provided between the upper hanging frame 7 and the wave-breaking wall 2. The limiting wheel 12 presses tightly against the front side of the wave-breaking wall 2 to prevent the track mechanism from disengaging. The limiting wheel 12 is mounted on the positioning rod 11, and the positioning rod 11 is fixed to the upper hanging frame 7.

[0055] The limiting wheel 12 can prevent the upper bracket 7 from detaching from the wave wall 2 under the overall gravity of the track mechanism, and does not affect the lateral movement of the upper bracket 7.

[0056] The adjustable angle structure includes a connecting frame 13, a front lower hinge shaft 19, a front arc plate 20, and a front upper pin shaft.

[0057] The bottom end of the connecting frame 13 is hinged to the bottom front end of the beam 4 via the front lower hinge shaft 19. The front arc plate 20 is fixed on the connecting frame 13 and has a front arc groove 21. The front upper pin passes through the pin hole of the beam 4 and the front arc groove 21. The front arc groove 21 serves as a guide support structure for the front upper pin.

[0058] The adjustable angle structure includes a rear upper hinge shaft 22, a rear arc plate 23, and a rear lower pin shaft;

[0059] The rear end of the beam 4 is hinged to the rear transverse beam 14 via the rear upper hinge shaft 22. The rear arc plate 23 is fixed to the rear transverse beam 14 and has a rear arc groove 24. The rear lower pin passes through the pin hole of the beam 4 and the rear arc groove 24. The front upper pin and the rear lower pin are conventional parts and are not shown in the figure.

[0060] The hinged joints and curved grooves enable flexible adjustment. The double-hinged design at both ends of beam 4 enhances its slope adaptability, while the curved grooves provide an angle adjustment margin. The simple upper and lower adjustable angle structures allow beam 4 to be supported and rotated between the upper bracket 7 (connecting frame 13) and the rear transverse beam 14, thus meeting the construction needs of different slope sections and solving the problem that existing equipment cannot adapt to slopes.

[0061] Both the front upper pin and the rear lower pin are threaded shafts, and both ends of the threaded shafts are connected to clamping nuts (not shown in the figure).

[0062] After placing this utility model on the slope, the tilt angle of beam 4 can be fixed by tightening the clamping nut, ensuring construction stability. Both the threaded shaft and the clamping nut are conventional technologies and are not shown in the figure.

[0063] The limiting wheel 12 is installed on the front side of the upper bracket 7 via the positioning rod 11, and the limiting wheel 12 makes rolling contact with the front side of the wave-breaking wall 2;

[0064] The front transverse motor 10 and the rear transverse motor 15 are driven synchronously, causing the track mechanism to move laterally along the wave-breaking wall 2 and the foot wall 1.

[0065] The connection structure of the limit wheel 12 is simple and easy to manufacture.

[0066] During construction, the track mechanism is hoisted and placed between the retaining wall 1 and the wave-breaking wall 2. The upper and lower adjustable angle structures are adjusted to match the inclination angle of the beam 4 to the slope surface, and then the pins are tightened for fixation. The front traverse motor 10 and the rear traverse motor 15 work synchronously, driving the track mechanism to move laterally to the construction slope section, providing a foundation for the mechanized paving of the main paving mechanism of the slope paver. After one section of the slope is paved, the front traverse motor 10 and the rear traverse motor 15 work synchronously, driving the track mechanism to move laterally to the adjacent slope section to be constructed, achieving continuous paving. The spacing between the left and right track mechanisms can be customized according to the size of the concrete interlocking blocks to improve adaptability.

[0067] The above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the utility model without departing from the spirit and scope of the utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
