Description

Technical Field

[0001] This utility model relates to the field of precast beam spraying technology, and in particular to a fixed bracket for spraying markings on precast beams. Background Technology

[0002] During the construction phase of precast beams in highway and municipal precast beam yards, spraying markings is inconvenient, labor-intensive, and time-consuming. This often leads to disarray in the beam storage area due to untimely spraying. In order to complete the spraying marking work conveniently and quickly,

[0003] Because spraying markings is inconvenient, labor-intensive, and time-consuming, and often results in disarray of the beams in the storage area due to untimely spraying, the current practice for precast beam markings is to use a self-made steel reinforcement frame or to directly fix and spray the markings manually. The cut-out sheet metal is fixed to the web surface, and red paint is sprayed directly onto the sheet metal. After the paint is evenly applied, the sheet metal is removed, and the marking is complete. When using a steel reinforcement frame for fixing, the sheet metal does not adhere tightly and is prone to slipping, resulting in blurry or patchy paint. When fixing manually, two people are needed to hold the markings on both sides while one person sprays the paint, which is labor-intensive, and the paint can easily get onto the workers, making subsequent cleaning difficult. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of difficulty in spraying and displaying precast beams in the prior art, and to propose a fixed bracket for spraying and marking precast beams.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixed bracket for spraying markings on precast beams includes a body with locking wheels fixedly installed. A drive motor and two load-bearing columns are fixedly installed on the body. A lifting rod driven by the drive motor for vertical lifting is slidably fitted on the two load-bearing columns. A bearing seat is fixedly installed on each of the two lifting rods, and a marking panel is installed on the bearing seat. A locking mechanism for fixing the angle of the marking panel is provided on the lifting rod.

[0007] Preferably, the load-bearing column has a central cavity for sliding the lifting rod, and the load-bearing column has a guide elongated hole and a locking hole that connect the central cavity.

[0008] Preferably, the machine body has a limiting groove and a guide groove. A ball screw fixedly connected to the output end of the drive motor is rotatably installed in the limiting groove, and a movable nut that is slidably fitted in the limiting groove is installed on the ball screw. A limiting slider that is movably pulled by the movable nut and used to movably support the lifting rod is slidably fitted in the guide groove.

[0009] Preferably, a first connecting rod is pinned between the movable nut and the limiting slider, and a second connecting rod is pinned between the limiting slider and the lifting rod and is slidably fitted in the guide hole.

[0010] Preferably, the locking mechanism includes a connecting crossbar fixedly connected between two load-bearing columns, a support rod installed on the lower end pin of the marking panel, a traction bolt integrally connected to the lifting rod and movably connected to the support rod, and a locking screw threaded in the traction bolt.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A fixed bracket for spraying markings on precast beams includes a body 1 with locking wheels 18 fixedly installed. It should be noted that the locking wheels 18 can support the body 1 to make smooth displacement adjustments, so as to facilitate the repositioning of the sprayed markings.

[0024] The main body 1 is fixedly equipped with a drive motor 2 and two load-bearing supports 3, and a lifting rod 4 driven by the drive motor 2 for vertical lifting is slidably fitted into the two load-bearing supports 3. Please refer to the instruction manual for details. Figure 1 With appendix Figure 4 The body 1 has a limiting groove 7 and a guide groove 8. A ball screw 9, which is fixedly connected to the output end of the drive motor 2, is rotatably installed in the limiting groove 7. A movable nut 10 is slidably fitted in the limiting groove 7 on the ball screw 9. Under the guiding and limiting action of the limiting groove 7, the movable nut 10 can only move linearly back and forth. A limiting slider 11, which is movably pulled by the movable nut 10 and used to movably support the lifting rod 4, is slidably fitted in the guide groove 8. The movable nut 10 drives the two limiting sliders 11 to move in opposite directions to support the lifting rod 4 to move vertically.

[0025] Both lifting rods 4 are fixedly mounted with bearing seats 5, and each bearing seat 5 is fitted with a label panel 6. The lifting rods 4 are equipped with a locking mechanism for fixing the angle of the label panel 6. Please refer to the instruction manual for details. Figure 4 With appendix Figure 5The locking mechanism includes a connecting crossbar 14 fixedly connected between two load-bearing columns 3, a support rod 15 mounted on the lower end of the sign panel 6, and a traction bolt 16 integrally connected to the lifting rod 4 and movably connected to the support rod 15. A locking screw 17 is threaded in the traction bolt 16. The deflection angle of the sign panel 6 is adjusted by the bearing seat 5, and the deflected sign panel 6 is locked and limited by the support rod 15 to ensure that the sign panel 6 can be displayed at multiple angles.

[0026] The load-bearing column 3 has a central cavity 301 for sliding the lifting rod 4, and the load-bearing column 3 has a guide elongated hole 302 and a locking hole 303 that connect the central cavity 301. By tightening the screw in the locking hole 303, the lifting rod 4 can be limited and fixed on the load-bearing column 3.

[0027] Please refer to the instruction manual for details. Figure 1 With appendix Figure 4 A first connecting rod 12 is pin-connected between the movable nut 10 and the limiting slider 11, and a second connecting rod 13 is pin-connected between the limiting slider 11 and the lifting rod 4 and is slidably fitted in the guide elongated hole 302. By driving the movable nut 10, both lifting rods 4 can be driven simultaneously.

[0028] The support rod 15 has a traction hole 1501 for the sliding sleeve traction bolt 16 to meet the deflection angle requirements of the support rod 15.

[0029] It should be noted that the specific model and specifications of the drive motor 2 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] The drive motor 2 is turned on by controlling the machine body 1. The drive motor 2 controls the ball screw 9 to rotate, so that the moving nut 10 moves linearly along the limiting groove 7.
