Description

Technical Field

[0001] The present invention relates to the field of slip form construction of highway slope protection frameworks, and particularly to a concrete discharging assisting mechanism for slip form construction of arched slope protection frameworks on highway slopes. Background Art

[0002] In the construction of highway facilities, the slope protection project is an important link to ensure the stability of the project and prevent soil erosion. The traditional construction of slope protection frameworks mainly adopts the casting process, in which concrete is poured into the formwork manually or by using mechanical equipment and allowed to solidify to form the slope protection framework. This process has high construction costs, low construction efficiency, and poor construction quality.

[0003] As an advanced construction technology for slope protection frameworks, the slip form construction technology forms slope protection frameworks by the movement of slip form equipment on slopes. It has been gradually adopted because of its advantages such as fast construction speed, good forming quality, and low labor intensity. However, the existing slip form construction equipment for arched slope protection frameworks still has obvious limitations in practical applications. The currently designed slip form construction equipment for arched slope protection frameworks mainly relies on gravity and the extrusion force on the inner wall of the equipment to push the concrete out. This design can ensure the normal operation of the equipment during normal slip form paths and upward slip form construction. However, when the equipment is under slip form construction along the construction trajectory downward, due to the action of gravity, the concrete will slide backward, and the equipment cannot provide enough extrusion force to push the concrete out, thus affecting the quality and efficiency of slip form construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a concrete discharging assisting mechanism for slip form construction of arched slope protection frameworks on highway slopes to solve the problem that the concrete cannot be pushed out during downward slip form construction due to the action of gravity.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions to achieve.

[0006] A concrete discharging assisting mechanism for slip form construction of arched slope protection frameworks on highway slopes includes a basic framework, which is composed of a slip form module and a auger module. The slip form module consists of a hopper, a forming template, and a connecting frame; the auger module is installed inside the hopper through an end face mounting plate and is connected to a motor through a transmission shaft and a coupling, and rotates under the drive of the motor to push the concrete out.

[0007] The auger module includes spiral stirring blades, which are designed to be in full contact with the concrete and provide thrust to ensure that the concrete can be smoothly discharged from the discharge port of the hopper into the forming template.

[0008] The auger module is located below the injection port of the hopper so that the concrete can be immediately stirred and pushed after being injected.

[0009] The inside of the aggregate hopper further includes a concrete flow sensor, which is installed on the concrete discharge path to detect the concrete flow state and monitor the concrete discharge situation.

[0010] The connecting frame is used to connect the mounting plate, the aggregate hopper, the forming template and the auger module to ensure that these components are correctly aligned and firmly installed.

[0011] The mounting plate is used to connect and fix this mechanism to the whole machine equipment.

[0012] The beneficial effects of the present invention are:

[0013] By installing an auger module inside the aggregate hopper, the auger module is connected to the motor through a transmission shaft and a coupling. When concrete is injected from the injection port of the aggregate hopper, the spiral stirring blades on the auger module will rotate driven by the motor, pushing the concrete out of the discharge port of the aggregate hopper into the inside of the forming template. The concrete will be extruded into a slope protection skeleton under the action of the boundary pressure of the forming template to meet the construction requirements. The design of the auger module ensures the uniform distribution and discharge of concrete in the aggregate hopper, which helps to form a uniform slope protection surface and improve the construction quality.

[0014] By installing a concrete flow sensor inside the aggregate hopper, the concrete flow sensor is installed on the concrete discharge path to detect the concrete flow state and monitor the concrete discharge situation. When the mechanism is in the position of downward slip form construction, due to the action of gravity, the concrete injected from the injection port of the aggregate hopper will slide backward and cannot be normally discharged from the discharge port of the aggregate hopper. At this time, the concrete flow sensor will feedback the monitored concrete discharge flow rate to the control unit of the whole machine, and the control unit controls the motor to change the motor speed, thereby changing the speed of the spiral stirring blades on the auger module, so that the spiral stirring blades have sufficient thrust to smoothly push the concrete out of the discharge port of the aggregate hopper into the inside of the forming template. The concrete will be extruded into a slope protection skeleton under the action of the boundary pressure of the forming template to meet the construction requirements. Description of the Drawings

Based on the embodiments in the specific implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0024] The present invention will be described in detail below in conjunction with the drawings and specific implementation manners.

[0025] Embodiment 1

[0026] As Figures 1-5 shown, a concrete discharge boosting mechanism for slip form construction of highway slope arch retaining wall skeletons consists of a slip form module 16 and an auger module 11 to form a framework. The slip form module 16 consists of an aggregate hopper 1, a forming template 4 and a connecting frame 5; the auger module 11 is installed inside the aggregate hopper 1 through an end face mounting plate 17 and is connected to the motor 6 through a transmission shaft 7 and a coupling 8, and rotates under the drive of the motor 6 to push the concrete out.

[0027] The auger module 11 includes spiral stirring blades 9, and the spiral stirring blades 9 are designed to be in full contact with the concrete and provide a thrust force to ensure that the concrete can be smoothly discharged from the aggregate hopper discharge port 13 into the forming template 4.

[0028] The auger module 11 is located below the aggregate hopper injection port 12 so that the concrete can be immediately stirred and pushed after being injected.

[0029] In this case, when the slip form mechanism is located at Figure 6When working at the location, the forming template 4 is in direct contact with the working plane 14. Concrete is injected from the aggregate hopper injection port 12. Driven by the motor 6, the spiral stirring blades 9 on the auger module 11 push the concrete forward and discharge it.

[0030] In this device, by installing the auger module 11 inside the aggregate hopper 1, the auger module 11 is connected to the motor 6 through the transmission shaft 7 and the coupling 8. When concrete is injected from the aggregate hopper injection port 12, the spiral stirring blades 9 on the auger module 11 will rotate driven by the motor, pushing the concrete to be discharged from the aggregate hopper discharge port 13 into the inside of the forming template 4. The concrete will be extruded into a slope protection skeleton under the action of the boundary pressure of the forming template 4 to complete the construction requirements. The design of the auger module ensures the uniform distribution and discharge of concrete in the aggregate hopper, which helps to form a uniform slope protection surface and improve the construction quality.

[0031] Embodiment 2

[0032] As Figures 1-5 shown, a concrete discharge boosting mechanism for slip form construction of arch slope protection skeletons on highway slopes consists of a slip form module 16 and an auger module 11 to form a framework. The slip form module 16 consists of an aggregate hopper 1, a forming template 4 and a connecting frame 5; the auger module 11 is installed inside the aggregate hopper 1 through an end face mounting plate 17 and is connected to the motor 6 through the transmission shaft 7 and the coupling 8, and rotates driven by the motor 6 to push the concrete to be discharged.

[0033] The auger module 11 includes spiral stirring blades 9, and the spiral stirring blades 9 are designed to be in full contact with the concrete and provide thrust to ensure that the concrete can be smoothly discharged from the aggregate hopper discharge port 13 into the inside of the forming template 4.

[0034] The auger module 11 is located below the aggregate hopper injection port 12 so that the concrete can be stirred and pushed immediately after being injected.

[0035] The inside of the aggregate hopper also includes a concrete flow sensor 10. The concrete flow sensor 10 is installed on the concrete discharge path to detect the concrete flow state and monitor the concrete discharge situation.

[0036] In this case, when the slip form mechanism moves along the construction track 15 to Figure 7 the location, the concrete in the aggregate hopper will slide backward under the action of gravity and cannot be normally discharged from the aggregate hopper discharge port 13. By adjusting the rotation speed of the motor 6, the rotation speed of the spiral stirring blades 9 on the auger module 11 is changed, so that the spiral stirring blades 9 can smoothly push the concrete forward and discharge it.

[0037] This device installs a concrete flow sensor 10 inside the aggregate hopper 1. The concrete flow sensor 10 is installed on the concrete discharge path and is used to detect the concrete flow state and monitor the concrete discharge situation. When the slip form mechanism moves along the construction trajectory 15 to Figure 7 the location, due to the gravitational force, the concrete injected from the aggregate hopper inlet 12 will slide backward and cannot be discharged from the aggregate hopper outlet 13 normally. At this time, the concrete flow sensor 10 will feedback the monitored concrete discharge flow rate to the control unit of the whole machine, and the control unit controls the motor 6 to change the motor speed, thereby changing the speed of the spiral stirring blades 9 on the auger module 11, so that the spiral stirring blades 9 have sufficient thrust to smoothly push the concrete out of the aggregate hopper outlet 13 into the inside of the forming template 4, and the concrete will be extruded into a slope protection skeleton under the action of the boundary pressure of the forming template 4 to meet the construction requirements.
