DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-4 As shown, a road construction machinery safety alarm provided by an embodiment of the utility model includes a mother seat 1, a quick-release tenon 2 is arranged on the top of the mother seat 1, and a bearing seat 3 is fixedly installed on the outer wall of the top of the tenon 2, a support frame 4 is arranged on the outer wall of one side of the top of the tenon 2, and a forward and reverse motor 5 is installed on the top of the support frame 4 by bolts, a support shaft 6 is inserted into the top of the bearing seat 3, a driven gear 12 is arranged on the top of the support shaft 6, a driving gear 13 meshing with the driven gear 12 is installed on the output shaft of the forward and reverse motor 5, a synchronous shaft 8 is arranged on the top of the driven gear 12, a mounting platform 9 is fixedly installed on the top of the synchronous shaft 8, and an alarm light 10 is arranged on the top of the mounting platform 9, and a horn 11 is fixedly installed on the outer wall of one side of the synchronous shaft 8.

[0023] Specifically, in this embodiment, it includes a mother seat 1, a quick-release tenon 2 is arranged on the top of the mother seat 1, the tenon 2 is inserted into the inside of the mother seat 1 to achieve the purpose of quick disassembly and assembly, and a bearing seat 3 is fixedly installed on the outer wall of the top of the tenon 2, a support frame 4 is arranged on the outer wall of one side of the top of the tenon 2, and a forward and reverse motor 5 is installed on the top of the support frame 4 by bolts, the support frame 4 is a C-shaped structure, and the C-shaped support frame 4 is used to achieve stable installation of the forward and reverse motor 5, or the support frame 4 is a vertical rod shape, according to different designs, the support frame 4 can also be a vertical structure, and it can also well achieve the fixed installation of the forward and reverse motor 5 on one side of the top of the tenon 2 through the support frame 4, a support shaft 6 is inserted into the top of the bearing seat 3, and a driven gear 12 is arranged on the top of the support shaft 6. A driving gear 13 meshing with a driven gear 12 is installed on the output shaft of the motor 5. The forward and reverse motor 5 is started to drive the driving gear 13 to rotate, and the driving gear 13 drives the driven gear 12 to transmit, so that the driven gear 12 drives the support shaft 6 and the synchronous shaft 8 to rotate together, so that the horn 11 located on one side of the synchronous shaft 8 and the alarm light 10 located on the top of the synchronous shaft 8 can rotate and adjust the angle to achieve multi-position warning effects. A synchronous shaft 8 is arranged on the top of the driven gear 12, and a mounting platform 9 is fixedly installed on the top of the synchronous shaft 8, and an alarm light 10 is arranged on the top of the mounting platform 9. Warning light is emitted by the alarm light 10 to alert the people next to the construction equipment. A horn 11 is fixedly installed on the outer wall of one side of the synchronous shaft 8, and a warning sound is emitted by the horn 11.

[0024] The utility model provides a road construction machinery safety alarm, which adopts a forward and reverse motor 5 to drive the rotation of gears (a driving gear 13 and a driven gear 12), so that the speaker 11 can be adjusted at multiple angles to achieve warning sounds in different directions and achieve a better warning effect. The quick-release mother seat 1 and tenon 2 are easy to install and disassemble the alarm.

[0025] In one embodiment of the present invention, a protective cover 7 is sleeved on the outside of the driven gear 12 and the driving gear 13, and a hole for the synchronization shaft 8 to pass through is set on the top of the protective cover 7. The hole is set so that the synchronization shaft 8 can better pass through the protective cover 7 without motion interference. The protective cover 7 is used to protect the driven gear 12 and the driving gear 13 from being damaged by the external environment.

[0026] A support rod is welded on the outer wall of one side of the bottom of the protective cover 7, and the bottom of the support rod is fixedly mounted on the support frame 4, so that the protective cover 7 is fixed on the support frame 4. When the forward and reverse motor 5 rotates, the protective cover 7 is in a fixed state, thereby achieving better transmission using the driven gear 12 and the driving gear 13.

[0027] In this embodiment, the horn 11 rotates along with the synchronous shaft 8, and the rotation angle of the horn 11 is 0-180°. By using the horn 11 that rotates 180 degrees, when the construction machinery moves forward, the horn 11 can be directed in the direction of the machine's advance. When the construction machinery moves backward, the horn 11 can be directed in the direction of the machine's retreat, so as to better remind passers-by and achieve an excellent warning effect.

[0028] Specifically, holes 14 are opened on the outer walls around the mother seat 1, and oblique grooves 15 are arranged at the holes 14. Installation grooves are arranged on the outer walls around the tenon 2, and elastic card joints 16 are arranged inside the installation grooves through springs. The elastic card joints 16 are inserted into the inside of the through holes 14 through the oblique grooves 15. When people install the alarm, the tenon 2 can be inserted into the inside of the mother seat 1. At this time, the elastic card joint 16 on the tenon 2 contacts the oblique groove 15, and the elastic card joint 16 is squeezed and retracted. When the elastic card joint 1 6 continues to go down over the position of the inclined slot 15, so that the elastic clamping joint 16 enters the interior of the through hole 14, so that the elastic clamping joint 16 is clamped in the through hole 14 to achieve the fixed installation of the tenon 2 on the female base 1. When removing the connection between the tenon 2 and the female base 1, the operator can use a tool to squeeze the elastic clamping joint 16 from all sides of the female base 1, so that the elastic clamping joint 16 retracts in the through hole 14, and by lifting the tenon 2 upward, the tenon 2 and the female base 1 can be quickly disassembled and installed.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
