Description

Technical Field

[0001] The present invention relates to the technical field of highway maintenance, and in particular to a highway maintenance device and a use method thereof. Background Art

[0002] The literal meaning of highway is a public road, a public transportation road, which can be used by many vehicles such as cars, bicycles, rickshaws, horse-drawn carriages, and pedestrians. Of course, different highways have different restrictions. It is also called a road in the folk. Existing two-way urban highways mostly use guardrails to separate the direction of highway traffic, thereby effectively preventing pedestrians from crossing the road and vehicles from driving in the opposite direction. Among them, the guardrails installed on the highway are prone to paint peeling and peeling after long-term use, making the guardrails easy to rust and unsightly, so it is necessary to maintain the highway guardrails by painting. Existing guardrails installed on highways are mostly painted manually, and the maintenance efficiency is low. Therefore, how to propose a maintenance method for efficiently and quickly painting highway guardrails is particularly important. In view of this, we propose a highway maintenance device and its use method. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a highway maintenance device and a method of use thereof to solve the current technical problem of low efficiency in manually painting highway guardrails.

[0004] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is as follows: a highway maintenance device is designed, including a carrier, a lift, and also including: an adjustment mechanism, a shielding mechanism, a smearing mechanism and a dripping mechanism; a carrier, wherein a support frame is provided at the movable end of the carrier; at least two adjustment mechanisms are arranged on the support frame in a horizontal structure; a shielding mechanism is arranged at the end of the adjustment mechanism; wherein the internal gap of the shielding mechanism constitutes a maintenance spraying chamber; two lifts are arranged on both sides of the shielding mechanism through a mounting frame; a smearing mechanism is passed through the maintenance spraying chamber and connected to the lift, and a dripping mechanism is arranged linearly and evenly at intervals on the top of the shielding mechanism, wherein the carrier and the adjustment mechanism, the shielding mechanism lift, the smearing mechanism and the dripping mechanism constitute a mobile highway guardrail smearing structure.

The present invention, through the arrangement of the hinge seats A and B, uses the push rod to cause the sleeve rod and the extension rod to extend and retract, thereby controlling the bending deformation function of the shielding mechanism and the painting mechanism, and is used to adapt to the synchronous painting operation of the curved section of the highway guardrail, thereby meeting the actual working requirements of the highway guardrail.

[0006] Preferably, the shielding mechanism includes: a shielding unit A, a shielding side, a shielding unit B, a shielding frame, and a flap; two shielding units A are symmetrically arranged on the two hinge blocks B; and a plurality of shielding units B are sequentially arranged between the two shielding units A, wherein the shielding units A and B, as well as the adjacent shielding units B, are connected by flaps. The present invention utilizes the shielding units A, B, and flaps to shield both sides of the coating mechanism, thereby preventing paint from splashing onto the road and contaminating oncoming vehicles due to the centrifugal force of the coating mechanism during operation.

[0007] Preferably, the flap is in a "J" shape when viewed from the side, wherein the flap is in a trapezoidal shape when viewed from above, and the large end of the flap is close to the smearing mechanism, wherein the shielding unit A, the shielding unit B, and the flap are half-wrapped in the smearing mechanism. The present invention arranges the flap in a trapezoidal shape when viewed from above to match the shielding unit A and the shielding unit B with the shape of the flap, so that the shielding unit A and the shielding unit B can be adaptively deformed synchronously when the bending guardrail is being applied, and utilizes the shape of the flap that is adapted to the shielding unit A and the shielding unit B, so that the shielding unit A and the shielding unit B further improve the deformation and bending path of the shielding unit A and the shielding unit B, as well as the shielding unit B and the shielding unit B, during the rotation adjustment process.

[0011] Preferably, the drip mechanism comprises a plurality of storage bins and spray heads, with the storage bins being linearly and evenly spaced apart on top of the shielding unit A and shielding unit B, respectively. The spray heads are connected to the carrier pump via the storage bins and a hose. The present invention pumps paint from the storage bins via the carrier pump and hose, and the paint drips onto the brush surface via the spray heads.

[0033] Specifically, the adjustment mechanism 2 includes: a sleeve rod 201, an extension rod 202, and a push rod 203; at least two sleeve rods 201 are arranged horizontally on the support frame through a hinge seat A; the extension rod 202 is inserted into the sleeve rod 201 and extends to the outside of the sleeve rod 201; wherein, a hinge seat B is arranged at the end of the extension rod 202; the push rod 203 is arranged on the outer wall of the sleeve rod 201 through a hinge seat C; wherein, the movable end of the push rod 203 is arranged on the outer wall of the extension rod 202 through a hinge seat D, wherein the sleeve rod 201 and the extension rod 202 form a telescopic structure. The present invention, through the arrangement of the hinge seats A and B, uses the push rod 203 to cause the sleeve rod 201 and the extension rod 202 to be extended and retracted, thereby controlling the bending deformation function of the shielding mechanism 3 and the coating mechanism 5, so as to adapt to the synchronous coating operation of the curved road section of the highway guardrail, thereby meeting the actual working requirements of the highway guardrail coating.

[0034] Furthermore, the shielding mechanism 3 includes a shielding unit A301, a shielding side 3011, a shielding unit B302, a shielding frame 3021, and a flap 303.

A plurality of shielding units B302 are sequentially arranged between the two shielding units A301, wherein shielding units A301, shielding units B302, and adjacent shielding units B302 are connected by flaps 303. The present invention utilizes the shielding units A301, shielding units B302, and flaps 303 to shield both sides of the coating mechanism 5, thereby preventing paint from splashing onto the road and contaminating oncoming vehicles due to the centrifugal force of the coating mechanism 5 during operation.

[0035] Furthermore, the flap 303 is in a "J" shape when viewed from the side, wherein the flap 303 is in a trapezoidal shape when viewed from above, and the large end of the flap 303 is close to the smearing mechanism 5, wherein the shielding unit A301, the shielding unit B302, and the flap 303 are half-wrapped in the smearing mechanism 5. The present invention sets a trapezoidal flap 303 in a top view, which is matched with the shape of the flap 303, so that the shielding unit A301 and the shielding unit B302 can be adaptively deformed synchronously when the bending guardrail is being painted.

The present invention uses the motor 503 to drive the shaft 501 and the brush 502 to achieve the basic work of efficiently painting highway guardrails.

[0038] It is worth emphasizing that the shaft 501 is composed of two universal joints 5011 and a connecting shaft 5012. The outer walls of the two universal joints 5011 are covered with protective rubber sleeves 5013. The universal joints 5011 form a universal transmission structure through the connecting shaft 5012. The present invention, by rotatably disposing the two universal joints 5011 and the connecting shaft 5012, enables the universal joints 5011 to perform multi-angle transmission operations, allowing the coating mechanism 5 to bend and adapt to coating operations on curved highway guardrail ends. The protective rubber sleeves 5013 are used to wrap the universal joints 5011 to prevent paint from seeping into the shaft 501 after drying, thereby hindering the filling of the shaft 501 and affecting the multi-angle universal transmission operation of the universal joints 5011.

When the highway guardrail maintenance device moves to the curved section of the guardrail, the vehicle 1 is synchronously turned to move, so that the shielding unit A301 in the front section remains parallel to the guardrail, and then the push rod 203 is synchronously operated to cause the sleeve rod 201 and the extension rod 202 to extend and retract, so as to control the bending deformation of the shielding mechanism 3 and the coating mechanism 5. At this time, the vehicle 1 is used to The two universal joints 5011 and the connecting shaft 5012 are rotatably arranged so that the universal joints 5011 can perform multi-angle transmission work, so that the smearing mechanism 5 can cooperate with the bending work, and is hingedly connected in sequence through the flap 303 and a group of arranged shielding side frames 3011 and shielding frames 3021, and another group of arranged shielding side frames 3011 and shielding frames 3021 are only connected through the flap 303, and the shielding unit A301 is composed of two symmetrically hinged shielding side frames 3011; the shielding unit B302 is composed of two symmetrically hinged shielding frames 3021, so that the shielding mechanism 3 can perform two processing methods of positive angle bending and negative angle bending, and simultaneously use the reciprocating lifting measures of the elevator 4 to cooperate with the smearing mechanism 5 and the dripping mechanism 6 to perform the smearing work.
