Description

Technical Field

[0001] This utility model relates to the field of highway bridge construction technology, and in particular to a device for spreading water-retaining cloth in highway bridge construction. Background Technology

[0002] According to the patent document with publication number CN221681579U, the water-retaining cloth placed at the top of the support frame is pulled out and passed between the fixed roller and the movable roller. By pulling the threaded shaft, the movable roller is moved to one side, so that the water-retaining cloth is tightly attached to the surface of the fixed roller and the movable roller. As the lifting frame descends, the pressure cylinder also descends, and the pressure cylinder presses down on the water-retaining cloth and makes it adhere to the concrete layer of the road surface. Clean water is injected into the water storage tank through the water inlet. During the laying process, the water outlet valve is opened to guide the water into the water guide chamber through the water guide pipe. Finally, the water is sprayed onto the surface of the water-retaining cloth through the water spray nozzle at the bottom of the water guide chamber, thus completing the laying and watering of the water-retaining cloth.

[0003] The patent document states that after the water-retaining cloth is pressed down by the pressure cylinder and adhered to the concrete layer of the road surface, the water-retaining cloth, which is rigidly pressed down by the pressure cylinder, may scratch the stones and be damaged due to the presence of stones or other debris on the road surface. This affects the quality of the water-retaining cloth and results in unevenness after the water-retaining cloth is laid, thus affecting the quality of road construction. Utility Model Content

[0029] In this embodiment: the sweeping mechanism 7 includes a sweeping roller 701, which is located on the lower side of the frame 1. Two fixing plates are fixed on the other side of the bottom of the frame 1. The sweeping roller 701 is rotatably connected between the two fixing plates. A baffle 702 is provided on the outer side of the top of the sweeping roller 701 and is fixed between the two fixing plates. A connecting frame 703 for receiving stone debris is provided on one side of the sweeping roller 701. A collection box 704 is fixed on one side of the connecting frame 703, and a blower 705 is fixed on one side of the collection box 704. The collection box 704 and... A connecting plate is fixed between the frames 1. The connecting frame 703 is inclined. Several ventilation holes with a diameter smaller than that of stones and garbage are opened on one side of the collection box 704. A motor 706 is fixedly installed at the input end of the sweeping roller 701. The sweeping roller 701 is driven to rotate clockwise by the motor 706, sweeping stones and other garbage on the road into the connecting frame 703 on one side. The blower 705 sucks the stones and other garbage that have entered the connecting frame 703 into the collection box 704 for collection. The baffle 702 prevents stones and other garbage from splashing during the sweeping process of the sweeping roller 701.

[0030] In this embodiment: the elastic pressing mechanism 8 includes a support frame 801, which is located on one side of the fan 705. A pressure roller 802 is rotatably connected to the bottom of the support frame 801. Two springs 803 are fixed between the top of the support frame 801 and the bottom of the frame 1. The pressure roller 802 presses down on the water-retaining cloth. The elastic contraction of the two springs 803 causes the pressure roller 802 to move upward when it encounters stones or other debris, thus avoiding hard squeezing of the water-retaining cloth and causing scratches.

[0031] In this embodiment: support plates 2 are fixed on both the front and rear sides of the top of the frame 1. A water-retaining cloth roller 3 is rotatably connected between the two support plates 2. A square groove for the water-retaining cloth to pass through is opened on the top of the frame 1. A spray head 4 is fixed on one side of the bottom of the frame 1. A water tank 6 is fixed on one side of the top of the frame 1. A water pipe 5 is fixed between the water tank 6 and the spray head 4.

[0032] Working principle: The water-retaining cloth roller 3 is placed on top of the two support plates 2. One end of the water-retaining cloth passes through the square groove and then through the underside of the pressure roller 802 and is fixed to the road surface. Pulling the pull rod moves the frame 1 to the other side. The motor 706 drives the sweeping roller 701 to rotate clockwise, sweeping stones and other garbage on the road surface into the connecting frame 703 on one side. The blower 705 sucks the stones and other garbage that have entered the connecting frame 703 into the collection box 704 for collection. During this process, the baffle 70... 2. To prevent stones and other debris from splashing during the sweeping process, the pressure roller 802 presses down on the water-retaining cloth to ensure close contact between the water-retaining cloth and the road surface. When the water-retaining cloth under the pressure roller 802 encounters stones or other debris, the elastic force of the two springs 803 contracts, causing the pressure roller 802 to move upward, avoiding hard squeezing of the water-retaining cloth and causing scratches. Open the valve on the water pipe 5, and the water in the water tank 6 flows through the water pipe 5 to the spray head 4, and then flows down from the spray head 4 onto the laid water-retaining cloth.
