Abstract
Description
Technical Field
[0001] The present application relates to the field of guardrail measurement, and in particular to a municipal guardrail measurement device. Background Art
[0002] Municipal guardrails refer to the guardrails in the middle of urban roads or next to green belts. Their main function is to prevent pedestrians and vehicles from driving recklessly without following traffic rules. Since municipal guardrails are mostly composed of sections, most of the time the guardrails are not exactly the same length as the road. Therefore, the guardrails need to be cut to the appropriate length. Before this, the length of the guardrail needs to be measured. Since vehicles will drive according to the signs on the road, if the length of the municipal guardrail exceeds the range of the road signs, vehicles that still turn according to the signs may hit the guardrail and be damaged. Therefore, the cutting length needs to be as accurate as possible.
[0003] In response to the above-mentioned related technologies, the inventor believes that common municipal guardrails have the defect of being difficult to measure their length quickly and conveniently before being cut. The measurement result will directly affect the cutting result. If the guardrail is cut longer, it will affect the normal turning of the vehicle. If it is cut shorter, the vehicle will reduce the turning radius accordingly. Changes in driving habits will lead to a greater probability of collision. Therefore, a municipal guardrail measuring device is proposed to solve the above problem.
[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

DETAILED DESCRIPTION
[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The embodiment of the present application discloses a municipal guardrail measuring device. Figure 1 and Figure 2 A municipal guardrail measuring device includes a bottom plate 1, a telescopic rod and a top plate 2. The telescopic rod is arranged between the bottom plate 1 and the top plate 2. The telescopic rod includes an inner rod 8, a telescopic spring 9, a telescopic column 10, a pulsator 11 and an outer rod 12. The bottom wall of the inner rod 8 is fixedly connected to the top wall of the bottom plate 1. A cavity is opened in the outer rod 12. The top of the inner rod 8 extends into the cavity. The telescopic spring 9 is arranged between the top wall of the inner rod 8 and the top wall of the cavity. One end of the telescopic column 10 is rotatably connected to the top wall of the inner rod 8, and the other end passes through the top wall of the cavity. The pulsator 11 is arranged on the telescopic column 10. A through hole 13 is opened on the side wall of the outer rod 12. The pulsator 11 extends from the through hole 13. By rotating the telescopic column 10 by the pulsator 11, the staff can rotate the rotating disk 15 and the convex ball 16, thereby squeezing the rotating plate 17.
[0020] A placement groove 3 is provided on the top wall of the bottom plate 1, a pad 4 is installed on the bottom wall of the top plate 2, a first extension rod 5 is installed on the side wall of the bottom plate 1, and a second extension rod 6 is installed on the side wall of the top plate 2. The side walls of the first extension rod 5 and the second extension rod 6 are respectively provided with a blocking piece 7. The blocking pieces 7 provided on the first extension rod 5 and the second extension rod 6 can indicate the exact position, thereby facilitating the workers to accurately cut the guardrail;
[0021] Reference Figure 3 A motion cavity is provided in the top plate 2, and a fixing mechanism is installed in the motion cavity. The fixing mechanism includes a scale line 14, a rotating disk 15, a convex ball 16, a rotating plate 17, a return spring 18, an insert 19 and a plurality of insertion holes 20. The scale line 14 is installed on the top wall of the second extension rod 6, and a side rod 21 is installed on the side wall of the second extension rod 6. A side groove 22 is provided on the side wall of the motion cavity, and the side rod 21 is inserted into the side groove 22. Through the cooperation between the side rod 21 and the side groove 22, the extension of the first extension rod 5 is smoother, thereby facilitating the measurement of the guardrail length.
[0022] The rotating disk 15 is mounted on the top of the telescopic column 10, the convex ball 16 is mounted on the bottom wall of the rotating disk 15, the middle position of the rotating plate 17 is rotatably connected to the side wall of the motion cavity, the plug 19 is mounted on the side wall of one end of the rotating plate 17, and a number of holes 20 are evenly arranged on the bottom wall of the second extension rod 6. The return spring 18 is mounted between the bottom wall of the rotating plate 17 and the bottom wall of the motion cavity. The rotating disk 15 is located below the second extension rod 6. The distance between the bottom wall of the rotating disk 15 and the end of the rotating plate 17 away from the plug 19 is less than the outer diameter of the convex ball 16. When the convex ball 16 rotates to the position of the rotating plate 17, the rotating plate 17 can be rotated, and the plug 19 can be inserted into the hole 20, thereby limiting the position of the second extension rod 6, making it more convenient to record the measurement results.
[0023] The implementation principle of a municipal guardrail measuring device in an embodiment of the present application is as follows: when it is necessary to measure the length of the guardrail, the foot of the guardrail is placed in the placement groove 3, so that the first extension rod 5 and the second extension rod 6 are extended. After measuring the specified length, the impeller 11 can be rotated to make the telescopic column 10 drive the rotating disk 15 to rotate, so that the convex ball 16 is stuck between the rotating disk 15 and the rotating plate 17, so that the other end of the rotating plate 17 is tilted, and the plug block 19 is inserted into a socket 20, so that the position of the second extension rod 6 is fixed, thereby facilitating the staff to accurately record the measurement data and making it easier to cut the guardrail.
