Description

Technical Field

[0001] This utility model belongs to the field of highway maintenance and construction technology, and specifically relates to a cement concrete pouring device under a corrugated guardrail panel. Background Technology

[0002] With the gradual improvement of the social and economic level, in recent years, my country's expressways and national and provincial highways have begun to widely implement cement concrete hardening operations on earthen shoulders. However, due to traffic restrictions, the semi-closed construction of expressways and national and provincial highways cannot deploy pump trucks and other facilities for cement concrete pouring operations. The current mainstream pouring methods are either to directly pour cement concrete using cement mixer trucks after removing the original corrugated guardrail panels, or to pour manually without removing the corrugated guardrail panels. Both of these methods have the disadvantages of complex procedures, low construction efficiency, and high cost. Pouring after removing the original corrugated guardrail panels will also result in the loss of guardrail protection during the construction of the road, and the long material pouring journey is prone to concrete segregation, affecting the construction quality. At the same time, it is easy to cause pollution to the road surface and guardrail posts. Pouring manually requires a large number of workers, resulting in crowding and significant safety hazards. Utility Model Content

[0003] In view of the problems of complex cement concrete pouring process, low construction efficiency, high cost and great safety hazards in the existing construction of hardened earth road shoulders, this utility model provides a cement concrete pouring device under corrugated guardrails, which can pour concrete under the guardrails without removing the original corrugated beam guardrails.

[0004] This utility model provides the following technical solution:

[0005] The present invention relates to a cement concrete pouring device under a corrugated guardrail panel, comprising:

[0006] Device frame;

[0007] The casting funnel, installed inside the device frame, is an inverted truncated pyramid structure formed by welding four steel plates, with a feed pipe welded to the bottom;

[0008] The discharge chute is installed at the slotted position in the middle of the feed pipe via a rotary disc shaft, with the chute opening facing upwards and the head of the chute opening connected to the feed pipe.

[0009] A wheel is mounted on the side of the feed pipe via a wheel shaft.

[0010] The wheel lock is located above the wheel and is mounted on the wheel lock bracket via the wheel lock shaft. The wheel lock bracket is welded to the feed pipe and is used to restrict the rotation of the wheel.

[0011] A handle is installed on the front top of the device frame, with its bottom end welded to the top of the frame. Reinforcing threaded steel bars are welded between the top of the handle and the left and right sides of the top of the frame. The device frame is 1100mm high and 550mm wide, constructed from 50*50*5mm angle iron. The handle is made of hollow steel tubing.

[0012] The pouring funnel is 400mm high, 500mm wide at the top, and 200mm wide at the bottom. A feed pipe, a square tube with a 5mm wall thickness and a 200mm inner width, is welded to the bottom of the funnel. The middle section of the feed pipe is slotted using a cutting machine, and a 5mm thick horizontal insert is installed inside the pipe. The concrete feeding speed is controlled by adjusting the insertion depth of the insert. During concrete pouring, the concrete feeding speed is controlled by adjusting the insertion depth of the insert, thereby controlling the concrete pouring speed.

[0013] The discharge chute has a structure with welded sides and bottom, and a slotted top; the steel plate is 5mm thick, the bottom is 200mm wide, and the sides are 125mm high; the slotted head of the discharge chute connects to the lower opening of the feed pipe. The discharge chute is mounted inside the wheel disc via a rotating shaft.

[0014] The discharge trough head is connected to the wheel shaft at the center of the wheel through a wheel interface; the discharge trough rotates around the discharge trough head under the drive of the wheel, thereby changing the orientation of the discharge trough tail; the wheel interface is a bolt structure, installed on the feed pipe, with both ends used to connect the wheel shaft and the feed pipe respectively, and the wheel is installed on the wheel shaft.

[0015] The wheel is a steel wheel with multiple teeth evenly spaced circumferentially arranged on its rim. A handle is installed on the wheel to manually rotate it. When pouring concrete, the wheel is rotated by turning the handle, which in turn rotates the head of the discharge chute, thereby adjusting the angle of the entire discharge chute.

[0016] The wheel lock is mounted on the wheel lock bracket via the wheel lock shaft, and the rotation direction of the wheel lock is perpendicular to the rotation surface of the wheel. Limit plates are provided on both sides of the wheel lock, and the distance between the two limit plates is greater than the width of the wheel teeth. A wheel lock handle that drives the wheel lock to rotate is installed on the limit plate on one side of the wheel lock.

[0017] The limiting plate has a horizontal surface on one side and an arc-shaped surface on the other side. When the horizontal surface is rotated to the bottom, its height is higher than the wheel teeth. When the horizontal surface is rotated to the top, the two arc-shaped surfaces are inserted into both sides of the wheel teeth to restrict their movement. The wheel is a 7.5mm thick steel wheel with 24 protrusions. During concrete pouring, the wheel is rotated by turning the wheel handle, which drives the discharge chute to adjust its angle between 0-45°. After the angle adjustment is completed, the wheel lock is rotated by turning the wheel lock handle, which locks the wheel lock in place at the protrusion position, thus limiting the wheel.

[0018] The device frame is equipped with casters at the bottom.

[0019] The beneficial effects of this utility model are:

[0020] This utility model device has a simple structure, requires few personnel for construction, and can achieve the hardening and pouring of earthen road shoulders without removing corrugated guardrails. The process is simple, cost-effective, and has few safety hazards.

[0021] This utility model device is small in size, light in weight, and has few limitations. It can be operated by a single person and can avoid concrete segregation caused by excessive pouring distance during concrete pouring, thus improving construction quality. At the same time, this utility model device can be used as a medium to pour concrete supports from concrete mixer trucks onto road shoulders, avoiding concrete waste and pollution of the road surface and guardrail posts.

Threaded steel bars are welded between the top of the handle 2 and the two sides of the top of the device frame 1 for reinforcement. The pouring funnel 3 is welded from four 5mm thick steel plates. The middle section of the feed pipe 4 is slotted using a cutting machine and fitted with 5mm thick inserts 6. During the concrete pouring process, the pouring speed is controlled by controlling the insertion depth of the inserts 6.

[0032] like Figure 4 and 5 As shown, the wheel interface 12 is a bolted structure, installed on the feed pipe 4, with both ends used to connect the discharge chute 5 and the wheel shaft 9 respectively. The wheel 8 is fixed to the wheel shaft 9 with bolts. The wheel handle 10 is installed on the wheel 8. The wheel locking bracket 14 is welded to the feed pipe 4. The wheel locking shaft 13 is installed on the wheel locking bracket 14. The wheel lock 11 is installed on the wheel locking shaft 13. The wheel lock handle 15 is installed on the right side of the wheel lock 11. The discharge chute 5 is welded to the inside of the wheel 8. The rear end of the discharge chute 5 corresponds to the lower end of the feed pipe 4. When pouring concrete, the wheel 8 is rotated by rotating the wheel handle 10, which drives the discharge chute 5 to achieve an angle adjustment between 0-45°. After the angle adjustment is completed, the wheel lock 11 is rotated by rotating the wheel lock handle 15, which locks the wheel 8 at the protruding position, thus completing the limit of the wheel 8. Four casters 7 are installed on the lower part of the device frame 1. Specific implementation examples:

[0034] like Figure 7As shown, before concrete pouring, employees are arranged to hold handle 2 to stop the device in the predetermined position, adjust the wheel handle 10 to rotate the wheel 8 to drive the discharge chute 5 to a suitable angle, so that the outlet of the discharge chute is aligned with the foundation pit of the guardrail, rotate the wheel lock handle 15 to drive the wheel lock 11 to rotate, turn the two arc surfaces of the wheel lock 11 to the bottom, so that the wheel lock 11 is engaged with the wheel teeth of the wheel 8, and the two sides of the wheel teeth are limited by the limit plates inserted on both sides of the wheel lock 11, thereby completing the limiting of the wheel 8 and the discharge chute 5.

[0035] When pouring concrete, park the concrete mixer truck at the designated location and align the discharge port of the concrete mixer truck with the pouring funnel 3 of this utility model device. The concrete is poured into the earthen shoulder through the feed pipe 4 and the discharge chute 5. When it needs to be moved, arrange for employees to hold the handle 2 and slowly push the device forward at the same speed as the cement concrete mixer truck to complete the concrete pouring operation for hardening the earthen shoulder.
