Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically a marking device for bridge construction. Background Technology

[0002] Road markings are required on bridge and road surfaces to ensure driving safety. Commonly used materials for road markings fall into four categories: room-temperature solvent-based, heated solvent-based, hot-melt, and two-component. Since road markings applied to bridge surfaces must withstand sun, rain, wind, snow, and ice, their performance requirements are more stringent. Firstly, they must have a short drying time and be easy to apply to minimize traffic disruption. Secondly, they must have strong reflectivity, bright colors, and high gloss to ensure good visibility both day and night, guaranteeing driving safety and extending their service life.

[0003] Existing bridge construction marking devices are often cumbersome to use, making it inconvenient for workers to apply the markings. However, during bridge construction, markings are only one part of the process and need to be applied quickly to avoid affecting the bridge's traffic flow. Furthermore, if the markings cannot be applied neatly, rework is required, delaying the progress. Utility Model Content

[0004] The purpose of this invention is to provide a marking device for bridge construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bridge construction marking device includes a base, with a movable wheel on the lower side of the base, a push rod on one side of the base, an electric telescopic rod on the top of the base, fixing blocks on both sides of the electric telescopic rod, the bottom surface of the fixing blocks being fixed to the top of the base, an extension rod on the upper side of the electric telescopic rod, a control box on the top of the extension rod, and a brush head on the upper part of the control box.

[0007] The extension rod has a fixing rod on its side wall, and a pointer is provided on the lower side of the fixing rod.

[0008] The electric telescopic rod has scale lines on its front side.

[0009] A sliding rod is provided on the lower side of the brush head, inside the control box, and a ball screw is provided at one end of the sliding rod.

[0010] Both ends of the ball screw are provided with bearing seats. A first pulley is provided on one end of the ball screw and outside the bearing seat. A belt is provided on the outside of the first pulley. A second pulley is provided on the inside of the belt. A motor is provided on the left side of the second pulley.

[0011] The beneficial effects of this invention are: it facilitates the application of markings by workers, greatly improving their efficiency. The left and right movement of the sliding rod causes the brush head at the upper end of the sliding rod to move left and right, allowing workers to apply markings horizontally, thus simplifying the operation.

[0016] A bridge construction marking device includes a base 1, a movable wheel 2 on the lower side of the base 1, a push rod 3 on one side of the base 1, an electric telescopic rod 4 on the top of the base 1, fixing blocks 5 on both sides of the electric telescopic rod 4, the bottom surface of the fixing blocks 5 being fixed to the top of the base 1, an extension rod 6 on the upper side of the electric telescopic rod 4, a control box 8 on the top of the extension rod 6, and a brush head 9 on the upper part of the control box 8.

[0017] exist Figure 1 and 2 In the middle section: A fixing rod 7 is provided on the side wall of the extension rod 6, and a pointer 71 is provided on the lower side of the fixing rod 7. A scale line 41 is provided on the front side of the electric telescopic rod 4. Through the base 1, moving wheel 2, push rod 3, electric telescopic rod 4, fixing block 5, extension rod 6, fixing rod 7, pointer 71, and scale line 41, the staff can push the push rod 3 to move the moving wheel 2 at the lower end of the base 1, which is convenient for the staff to apply bridge markings to different positions. After reaching the designated position, the staff first applies one marking and then opens the electric telescopic rod 4, which moves the electric telescopic rod 4 up or down. This causes the fixing rod 7 and pointer 71 on the right side of the electric telescopic rod 4 to move up or down simultaneously. The pointer 71 points to the scale line 41 on the front side of the electric telescopic rod 4 to judge the distance, making the marking more neat. The fixing block 5 can fix the electric telescopic rod 4 on the upper side of the base 1, which is convenient for the staff to apply the markings and also reduces the labor intensity.

[0018] exist Figure 1 , 2 In section 3: A sliding rod 91 is provided on the lower side of the brush head 9 inside the control box 8. A ball screw 92 is provided at one end of the sliding rod 91. Bearing seats 93 are provided at both ends of the ball screw 92. A first pulley 94 is provided at one end of the ball screw 92 and outside the bearing seat 93. A belt 95 is provided outside the first pulley 94. A second pulley 96 is provided inside the belt 95. A motor 97 is provided on the left side of the second pulley 96. The system consists of a brush head 9, a control box 8, a sliding rod 91, a ball screw 92, a bearing seat 93, a first pulley 94, a belt 95, a second pulley 96, and a motor 97. Turning on the motor 97 activates the second pulley 96, which in turn rotates the belt 95. The belt 95 then rotates the first pulley 94, which in turn rotates the ball screw 92. The bearing seats 93 at both ends of the ball screw 92 fix the screw in place. The rotation of the ball screw 92 causes the sliding rod 91 to move left and right, which in turn moves the brush head 9 at its upper end, allowing the operator to apply markings horizontally, thus facilitating operation.
