Description

Anticollision speculum equipment of municipal administration usefulness

Technical Field

The invention belongs to the field of corner reflectors, and particularly relates to an anti-collision reflector device for municipal administration.

Background

The road reflector is also called a wide-angle lens, a convex lens and a turning lens and is mainly used for various curves and intersections, the view field of a driver can be enlarged, and vehicles and pedestrians opposite to the curves can be found as soon as possible, so that the occurrence of traffic accidents is reduced; and the device is also used for anti-theft and monitoring dead angles of supermarkets. When the vertical rod on which the reflective mirror is positioned is violently collided by a vehicle, the vertical rod can incline and change the position, and the monitoring function of the reflective mirror on the intersection is invalid due to the change of the position of the reflective mirror. During the period that the vertical rod where the reflector is arranged is inclined and cannot be maintained in time, accidents are likely to happen, and casualties are caused.

In order to solve the problem that the reflector cannot continue to work effectively due to the fact that the vertical rod on which the reflector is mounted is collided, it is necessary to design a road reflector device which can still monitor a curve or an intersection normally under the condition that the vertical rod on which the reflector is arranged is collided and inclines.

The invention designs an anti-collision reflector device for municipal administration to solve the problems.

Meanwhile, in the process that the vertical rod is impacted to swing, the limitation on a plurality of degrees of freedom in the universal joint mechanism A is removed, the universal joint mechanism A drives the swing rod B installed in the vertical rod to swing through a series of transmission, the swing rod B drives the two arc plates to be separated from the corresponding shaft C and the shaft sleeve and remove the autorotation limitation on the shaft C and the shaft sleeve, and therefore the limitation on the plurality of degrees of freedom in the universal joint mechanism B is temporarily and instantly removed. The convex mirror drives the corresponding center post to generate self-adaptive adjustment swing relative to the vertical rod or the shell of the universal joint mechanism B under the action of self weight, and the center post connected with the convex mirror is always in a vertical state under the gravity traction of the convex mirror. The convex mirror only generates translation in the vertical direction or the horizontal direction relative to the ground in the process, the facing direction of the mirror surface of the convex mirror is not changed all the time, the effective monitoring state is kept for the curve or the intersection all the time, and traffic accidents caused by the fact that drivers or pedestrians cannot see the other side of the curve in the time period when the vertical rod is not maintained timely due to the fact that the vertical rod is inclined due to collision are prevented.

After the vertical rod is impacted and swung, the reset spring for resetting the swing plate B gradually overcomes the damping rod on the pull rope and drives the swing rod to swing back to the vertical position state in the vertical rod and finally limits a plurality of degrees of freedom in the universal joint mechanism B, so that the position of the convex mirror relative to the vertical rod is temporarily fixed after the convex mirror is subjected to self-adaptive translation, and the phenomenon that the convex mirror cannot effectively monitor a curve or a road junction due to shaking under the action of wind is avoided. The invention has simple structure and better use effect.

As shown in fig. 7 and 14, the two arc plates 42 are mounted at one end of a swing rod B39 through a connecting block 41; the inner wall of the arc plate 42 is provided with an arc rubber friction pad 43 matched with the corresponding friction wheel 44, and the friction pad 43 can improve the friction between the arc plate 42 and the central shaft C17 and the shaft sleeve 11 of the universal joint mechanism B5, so that the two arc plates 42 arranged at the tail end of the swing rod B39 can effectively limit the central shaft C17 and the shaft sleeve 11 of the universal joint mechanism B5.

Under the condition that a plurality of degrees of freedom in the universal joint mechanism are not limited, the convex mirror 6 in the invention performs self-adaptive translation under the action of self weight and always keeps a working angle at a road corner.

The universal joint mechanism A2 and the universal joint mechanism B5 both adopt the cross universal joint principle.

The damping rod 38 of the present invention is known in the art.

The working process of the invention is as follows: in the initial state, the center pillar 12 in the gimbal mechanism a2 is in the vertical state. A gasket 3 is installed between the housing 7 of the gimbal mechanism a2 and the flange 1 to restrict several degrees of freedom in the gimbal mechanism a2 so that the vertical rod 4 is in a vertical state. The shaft a10 and the shaft B13 in the gimbal mechanism a2 are both horizontal. The two swing rods A35 are both in a horizontal state. Reset spring 45 is in tensile energy storage state, and pendulum rod B39 drives two arc plates 42 and sticiss two friction pulley 44, restricts the rotation of axle C17 and axle sleeve 11 among the universal joint mechanism B5 to a plurality of degrees of freedom in the restriction universal joint mechanism B5, and then to the restriction of relative motion between center pillar 12 among the universal joint mechanism B5 and the corresponding casing 7, prevent that convex mirror 6 from taking place the swing under the effect in the wind. The center pillar 12 in the gimbal mechanism B5 is in a vertical state.

When the vertical rod 4 is violently impacted, the vertical rod 4 tilts, meanwhile, the vertical rod 4 drives the shell 7 in the universal joint mechanism A2 to powerfully damage the gasket 3 between the shell 7 and the flange 1, and the gasket 3 is instantaneously cracked and the limitation on the universal joint mechanism A2 is removed.

The oscillation of the housing 7 of the gimbal mechanism a2 with respect to the column 12 therein can be decomposed into an oscillation about the axis a10 direction and an oscillation about the axis B13 direction.

When the housing 7 swings around the shaft a10 relative to the center pillar 12, that is, the center pillar 12 drives the middle ring 8 to swing around the shaft a10 relative to the housing 7 through the shaft B13, at this time, the center pillar 12 and the middle ring 8 are relatively stationary, the spur gear a14 mounted on the shaft B13 drives the shaft C17 and the middle ring 8 to synchronously rotate around the central axis of the shaft a10 through the toothed ring 15 and the spur gear B18, the middle ring 8 drives the shaft sleeve 11 to synchronously rotate, and the shaft C17 and the shaft sleeve 11 are relatively stationary. The sleeve 11 drives the cylinder 20 to synchronously rotate relative to the housing 7, and the cylinder 20 drives the two bevel gears B22 mounted on the two shafts D21 to revolve around the central axis of the shaft a10 through the two shafts D21.

At the same time, the shaft C17 rotates the bevel gear a19 synchronously, the rotation speed of the bevel gear a19 is equal to and opposite to the rotation speed of the cylinder 20 about the central axis of the shaft a10, and the rotation speed of the cylinder 20 is equal to and opposite to the rotation speed of the bevel gear a19, so that the bevel gear a19 is stationary with respect to the cylinder 20, and the two spur gears B18 attached to the two shafts D21 and the bevel gear a19 are also stationary with respect to each other. The bevel gear A19 drives the bevel gear C23 to rotate at a constant speed through two relatively stationary bevel gears B22, and the rotation direction of the bevel gear C23 is opposite to that of the bevel gear A19.

Bevel gear C23 rotates shaft E24. A shaft E24 in the universal joint mechanism A2 drives a shaft G34 to rotate through a straight gear C26, a straight gear D27, a straight gear E28, a shaft F29, a straight gear F31, a straight gear G32 and a straight gear H33, and the shaft G34 drives two swing rods A35 arranged on the shaft G35 to swing synchronously. One swing rod A35 pulls the swing rod B39 to swing around the shaft H40 through the pull rope 36 provided with the damping rod 38, and the two arc plates 42 arranged at one end of the swing rod B39 drive the corresponding rubber pads to be separated from the two friction wheels 44 and remove the self-rotation limitation on the center shaft C17 and the shaft sleeve 11 of the universal joint mechanism B5. At the same time, the return spring 45 is further extended to store energy.

Due to the damping characteristic of the damping lever 38, when one of the swing levers a35 rapidly pulls the pull rope 36 downward, the damping lever 38 does not elongate but pulls the swing lever B39 downward together with the pull rope 36, so that the swing lever B39 swings.

When the two arc plates 42 drive the rubber pads to be separated from the friction wheels 44 and the self-rotation limitation of the shaft sleeve 11 and the shaft C17 in the universal joint mechanism B5 is released, the limitation of a plurality of degrees of freedom in the universal joint mechanism B5 is released instantly. The center pillar 12 in the gimbal mechanism B5 produces an adaptive swing about the corresponding axis a10 or axis B13 with respect to the corresponding housing 7 under the weight of the convex mirror 6. And the center pillar 12 in the gimbal mechanism B5 is always in the vertical state during the swinging relative to the housing 7, so that the convex mirror 6 only translates in the vertical or horizontal direction relative to the previous position after swinging along with the center pillar 12. The mirror surface of the convex mirror 6 always faces the intersection or curve it is monitoring.

After the center pillar 12 in the gimbal mechanism B5 swings, the state of the gimbal mechanism B5 tends to be stable. Thereafter, under the reset action of the reset spring 45, one end of the swing rod B39 gradually stretches the damping rod 38 through the pull rope 36, the swing rod B39 gradually swings back around the shaft H40 and finally drives the two arc plates 42 installed at one end of the swing rod B and the rubber pads installed on the arc plates 42 to press the two friction wheels 44 tightly, the rotation of the shaft C17 and the shaft sleeve 11 in the universal joint mechanism B5 is limited again, so that a plurality of degrees of freedom in the universal joint mechanism B5 are limited again, the center pillar 12 is prevented from swinging randomly relative to the shell 7, the convex mirror 6 installed on the center pillar 12 is prevented from swinging under the action of wind, and the convex mirror 6 is ensured to still effectively monitor a curve or an intersection under the inclined state of the vertical rod 4.

When the housing 7 in the gimbal mechanism a2 swings about the respective axis B13 relative to the center pillar 12, it can be seen that the center pillar 12 in the gimbal mechanism a2 swings about the axis B13 relative to the middle ring 8 and the housing 7. At this time, the housing 7 swings the middle ring 8 about the shaft B13 relative to the center pillar 12 via the boss 11 and the shaft C17. Spur gear a14 drives gear ring 15 to rotate relative to middle ring 8, gear ring 15 drives spur gear B18 to rotate, spur gear B18 drives spur gear a14 to rotate relative to housing 7 through shaft C17, shaft sleeve 11 is stationary relative to housing 7, and cylinder 20 is stationary relative to housing 7. The two bevel gears B22 do not revolve around the central axis of the shaft C17; the bevel gear A19 drives the shafts D21 corresponding to the two bevel gears B22 to rotate. The two bevel gears B22 drive the bevel gear C23 to rotate, and the rotation direction of the bevel gear C23 is opposite to the rotation direction of the bevel gear A19 and the rotation speed is equal.

The bevel gear C23 is rotated by a series of driving shafts G34, and the shafts G34 drive the two swing rods A35 to swing synchronously. One swing rod A35 pulls the swing rod B39 to swing around the shaft H40 through the pull rope 36 provided with the damping rod 38, and the two arc plates 42 arranged at one end of the swing rod B39 drive the corresponding rubber pads to be separated from the two friction wheels 44 and remove the self-rotation limitation on the center shaft C17 and the shaft sleeve 11 of the universal joint mechanism B5. At the same time, the return spring 45 is further extended to store energy.

After the relative swinging between the housing 7 and the center pillar 12 in the universal joint mechanism a2 around the axis a10 and the axis B13 is combined, the convex mirror 6 only translates in the vertical direction and the horizontal direction when the vertical rod 4 tilts in any direction, and the mirror surface of the convex mirror 6 always faces a curve or an intersection to normally monitor the intersection.

After the vertical rod 4 is erected again by the maintenance personnel, the gasket 3 is newly arranged between the shell 7 of the universal joint mechanism A2 and the flange 1, and then the normal use of the universal joint mechanism A2 can be recovered. During the re-erection of the vertical bar 4 by the service person, the housing 7 in the gimbal mechanism a2 swings back about the axis a10 and the axis B13 with respect to the respective center pillar 12. In the process, the universal joint mechanism A2 reversely rotates through a series of transmission shafts G34, and the shafts G34 drive the two swing rods A35 to synchronously and reversely swing. The swing link A35 which previously pulls the swing link B39 downwards through the pull rope 36 swings from bottom to top around the shaft G34, the pulling on the extended damping rod 38 is rapidly released, the other swing plate A swings from top to bottom around the shaft G34 to move to the initial position state, and the two swing links A35 do not pull on the damping rod 38. The two arc plates 42 still press the two friction wheels 44 and limit the rotation of the shaft C17 and the shaft sleeve 11 in the universal joint mechanism B5.

After the vertical rod 4 is erected again, waiting for a period of time, and after the damping rod 38 is gradually contracted to the length of the initial state, the vertical rod 4 is manually dumped quickly and the vertical state is restored quickly. In the process that the vertical rod 4 is quickly inclined and continues to be quickly erected, the swinging rod B39 drives the two arc plates 42 to remove the self-rotation limitation on the central shaft C17 and the shaft sleeve 11 in the universal joint mechanism B5 due to the fact that the vertical rod 4 is inclined, the damping rod 38 cannot be immediately stretched by the stretched return spring 45, the two arc plates 42 cannot be immediately reset and re-limit the shaft C17 and the shaft sleeve 11 in the universal joint mechanism B5, in the process that the vertical rod 4 is immediately erected after being inclined, the central column 12 in the universal joint mechanism B5 swings in a self-adaptive mode relative to the shell 7 under the gravity of the convex mirror 6 and is always in the vertical state due to the fact that the universal joint is not limited by the shaft C17 and the shaft sleeve 11 in the universal joint mechanism B, and therefore resetting of the universal joint mechanism B5 is completed. After the vertical rod 4 is erected for the second time for a period of time, the stretched damping rod 38 gradually contracts and recovers and the pull rope 36 is tightened again in the initial state.

Then, the gasket 3 is remounted between the case 7 of the gimbal mechanism a2 and the flange 1 to fixedly restrain the gimbal mechanism a 2.

In conclusion, the beneficial effects of the invention are as follows: in the universal joint mechanism A2, the shell 7 and the flange 1 are relatively fixed through the liner 3 which can be damaged by strong force, so that the liner 3 is broken when the vertical rod 4 is violently impacted, the vertical rod 4 swings laterally, the universal joint mechanism A2 can effectively buffer the impact on the vertical rod 4, the vertical rod 4 is prevented from being deformed due to the impact, and the damage degree of equipment due to the impact is reduced to the minimum.

Meanwhile, in the process that the vertical rod 4 is impacted to swing, the limitation on a plurality of degrees of freedom in the universal joint mechanism A2 is removed, the universal joint mechanism A2 drives a swing rod B39 installed in the vertical rod 4 to swing through a series of transmission, the swing rod B39 drives the two arc plates 42 to be separated from the corresponding shaft C17 and the shaft sleeve 11 and remove the self-rotation limitation on the shaft C17 and the shaft sleeve 11, and therefore the limitation on the plurality of degrees of freedom in the universal joint mechanism B5 is temporarily and instantly removed. The convex mirror 6 drives the corresponding center post 12 to generate self-adaptive adjustment swing relative to the vertical rod 4 or the shell 7 of the universal joint mechanism B5 under the action of self weight, and the center post 12 connected with the convex mirror 6 is always in a vertical state under the traction of the gravity of the convex mirror 6. In the process, the convex mirror 6 only translates in the vertical direction or the horizontal direction relative to the ground, the facing direction of the mirror surface of the convex mirror 6 is not changed all the time, the effective monitoring state is kept for the curve or the intersection all the time, and the traffic accident caused by the situation that a driver or a pedestrian cannot see the other side of the curve in the time period that the vertical rod 4 is not maintained in time because of the inclination caused by collision is prevented.

After the vertical rod 4 is impacted and swung, the reset spring 45 for resetting the swing plate B gradually overcomes the damping rod 38 on the pull rope 36 and drives the swing rod to swing back to the vertical position state in the vertical rod 4 and finally limits a plurality of degrees of freedom in the universal joint mechanism B5, so that the position of the convex mirror 6 relative to the vertical rod 4 is temporarily fixed after the convex mirror 6 is subjected to self-adaptive translation, and the phenomenon that the curve or the intersection cannot be effectively monitored due to the fact that the convex mirror 6 shakes under the action of wind is avoided.
