Description

Technical Field

[0001] The utility model relates to the field of highway engineering maintenance, in particular to a highway engineering maintenance device. Background Art

[0002] In highway engineering road construction, concrete is used to harden the road surface. After the concrete is poured, it can gradually solidify and harden mainly because of the cement hydration, which requires appropriate humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength continues to increase, the concrete must be maintained. During maintenance, it is necessary to use road maintenance equipment to spray water on the road surface to prevent the concrete from cracking.

[0003] The Chinese patent with the publication number CN216238034U discloses a road construction maintenance device for highway engineering, which is a winding component fixedly installed vertically and symmetrically on the upper surface of the vehicle body, and the winding component includes a first motor, a clutch, two support plates, a reel, a rotating shaft and a felt cloth. The upper surface of the vehicle body is provided with a conveying assembly, which includes a first bracket, two support rods, two pressure wheels and a driving component. The rear end face of the vehicle body is provided with a humidifying component, which includes two support plates, an infusion tube, multiple nozzles, a connecting pipe, a pressure pump and a water tank. The patent points out the defects of the prior art of using felt cloth to cover the concrete surface and spraying water on the surface of the felt cloth to ensure humidity, that is, manual work is used, which is time-consuming and labor-intensive, and the watering is uneven, resulting in low construction efficiency. Although the CN216238034U patent solves the shortcomings of the manual watering method, it is also accompanied by the following defects: 1. The nozzle of the spraying device is relatively fixed, and the spraying height cannot be adjusted. The scope of spraying maintenance is relatively limited, which is not convenient for watering the surrounding road surface. Furthermore, when watering the road surface, it is often necessary to perform multiple reciprocating operations to spray water on the road surface, and the use effect is poor; 2. When the spraying maintenance device replenishes water on the highway road surface, water will splash onto the surrounding pedestrians, so that subsequent work may not be able to successfully complete the operation of spraying the road surface.

[0020] The content of the utility model is clearly and completely described below in conjunction with the drawings and embodiments.

[0021] like Figure 1 The highway engineering maintenance device shown in the figure comprises a base 1 with rollers at the bottom for easy movement, a water tank 2 placed on the base, a water pump 3 installed beside the water tank, an adjustment plate assembly installed on the outside of the water tank, a group of nozzles 9 installed on the top of the adjustment plate assembly, and a baffle assembly installed on the top of the adjustment plate assembly and located above the nozzles. The water tank 2 is preferably fixed on the base 1 to ensure stability and safety.

[0022] like Figure 1 , Figure 2 As shown, the adjustment plate assembly includes two slotted plates 4 with opposite notches and vertically spaced apart, a sliding plate 6 that can be inserted into the two slotted plates, and vertical slide plates 7 with a T-shaped cross section are arranged on both sides of the sliding plate, and the web of the slide plate is inserted into the gap 5 between the two slotted plates 4, which is equivalent to the slide groove. First mounting holes 401 arranged at intervals are processed on the wing plates on both sides of the slotted plate, and second mounting holes 701 arranged at intervals are processed on both sides of the end plate of the slide plate. The height of the sliding plate can be adjusted by aligning the first mounting holes and the second mounting holes of different heights and inserting the positioning screws 8. The nozzle 9 is installed on the top of the sliding plate 6.

[0023] like Figure 3 , Figure 4 As shown, the baffle assembly includes a fixed plate 10 fixedly connected to the top of the slide plate 7 or can be made into one piece with the slide plate, a rotating shaft 11 installed horizontally between the two fixed plates, a top plate 14 fixedly installed on the rotating shaft, and a hanging plate 15 fixedly connected to both ends of the top plate. At least one end of the rotating shaft 11 passes through the fixed plate and is fitted with a rotating sleeve. It is also possible to symmetrically install a shaft sleeve 12 extending out of the outside of the fixed plate on the two fixed plates 10, install both ends of the rotating shaft 11 in the shaft sleeve, equip at least one end of the rotating shaft with a fastening bolt 13 that can be inserted into the rotating shaft, and fit a rubber pad 1301 on the fastening bolt. The fastening bolt presses the rubber pad to fit tightly against the shaft sleeve 12 to fix the rotating shaft. The surface of the rubber pad is relatively rough, and the friction between it and the shaft sleeve 12 is relatively large, which has a better effect of fixing the rotating shaft that is rotated in place.

[0024] The rotation of the rotating shaft 11 can drive the top plate 14 to adjust its angle. The top plate 14 and the hanging plate 15 form a baffle to prevent the water sprayed from the nozzle from splashing onto nearby objects or people.

[0025] The water inlet and the water outlet of the water pump 3 are connected to the water tank 2 and the nozzle 9 through pipelines, respectively, and the water in the water tank is pumped out by the water pump, and the water is sprayed on the road surface through the nozzle 9. The sliding plate 6 slides up and down inside the groove plate 4, and the height of the sliding plate 6 is fixed by the positioning screw 8, so as to adjust the height of the nozzle 9.

[0026] When the utility model is used, the height of the nozzle 9 is adjusted by sliding the sliding plate 6 up and down in the groove plate 4, and the second mounting hole 701 is aligned with the first mounting hole 401, and the positioning screw 8 is inserted to fix the height of the nozzle. Then the water pump 3 is turned on, and the nozzle 9 sprays water on the concrete pavement for maintenance. The height of the nozzle can be flexibly adjusted, which is convenient to operate and highly practical. The rotating shaft 11 is rotated to adjust the angle of the top plate 14, and the baffle member composed of the top plate and the hanging plate blocks the water sprayed to the sides and the top to avoid splashing the water on pedestrians or objects nearby.

[0027] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
