Description

Technical Field

[0001] The present application relates to the technical field of road facilities, and in particular to a fixing device and a photoelectric induction marking device. Background Art

[0002] Photoelectric induction signs are widely used in special sections such as tunnels, curves, uphill and downhill sections. They can clearly display the road contour to remind drivers to control their speed, thereby playing a traffic warning role and avoiding traffic accidents. However, photoelectric induction signs installed on the side of the road are easily damaged by vehicles or by the harsh external environment. According to relevant statistics, photoelectric induction signs have become the most frequently repaired and replaced electromechanical equipment in tunnels.

[0003] When installing a photoelectric induction sign, it is usually necessary to drill a fixing hole and a threading hole on the curbstone, then pass the power supply wire of the photoelectric induction sign through the threading hole on the curbstone and connect it to the mains to power the photoelectric induction sign, and then use screws to pass through the mounting hole on the photoelectric induction sign and the fixing hole on the curbstone to fix the photoelectric induction sign on the curbstone. The entire installation process is time-consuming. If the work is done when the road is open to traffic, it will bring personal risks to the installers, and closing the road will cause poor road operation. Utility Model Content

[0039] In view of the time-consuming installation problem of photoelectric induction signs in related technologies, the inventor of this application has conceived a new solution, which uses a hollow rod body to fix the photoelectric induction sign and accommodate the wires of the photoelectric induction sign. The photoelectric induction sign can be fixed on the curbstone by simply passing the hollow rod body through the threading hole on the curbstone and fixing the hollow rod body. The photoelectric induction sign can work normally after wiring. This method cleverly uses the hollow rod body to thread the wires, and the photoelectric induction sign can be installed by only opening a threading hole on the curbstone, which greatly improves the timeliness of the installation of the photoelectric induction sign.

[0040] First, see Figure 1 and Figure 2, the embodiment of the present application provides a fixing device 1, which is used to install and fix a photoelectric induction mark 2. The photoelectric induction mark 2 is an active road spike, and a wire 21 is arranged on it. The wire 21 is used to connect to a power source, such as a mains or a battery, so as to power the photoelectric induction mark 2. As an example, the photoelectric induction mark 2 also includes a shell 22 and a light-emitting member 23, the light-emitting member 23 is arranged in the shell 22 and electrically connected to the wire 21, and the light-emitting member 23 is used to emit light outside the shell 22 when the circuit is turned on. Exemplarily, the light-emitting member 23 includes an LED lamp. The number of light-emitting members 23 can be one or more, and more means two or more. In detail, the shell 22 is provided with a housing cavity 221 and a light-transmitting portion 222, the light-emitting member 23 is installed in the housing cavity 221, and the light emitted by the light-emitting member 23 is emitted from the shell 22 through the light-transmitting portion 222. Here, the light-transmitting portion 222 can be a light-through hole opened on the shell 22, or a transparent wall arranged on the shell 22. Usually, the light-transmitting portion 222 is arranged or arranged in a specific pattern, such as an arrow pattern, to enhance the indication effect of the photoelectric induction mark 2. A wire hole (not shown) is also provided on the shell 22, and one end of the wire 21 extends into the accommodating cavity 221 through the wire hole and is electrically connected to the light-emitting component 23. At the same time, a mounting hole 223 is also provided on the shell 22, and the mounting hole 223 is used to fix the photoelectric induction mark 2. Generally, mounting holes 223 are respectively provided on the two end edges of the shell 22, for example, the two end edges of the shell 22 are recessed inward to form a groove (not shown), and the mounting hole 223 is provided on the bottom wall of the groove. In addition, the photoelectric induction mark 2 can also include a controller 24, which is also provided in the accommodating cavity 221 and is electrically connected to the light-emitting component 23 through the wire 21.

[0041] Specifically, see Figures 1 to 3, the fixing device 1 includes a hollow rod body 11. The hollow rod body 11 refers to a hard tube structure with a hollow design inside. Optionally, the hollow rod body 11 is a rigid straight rod. The hollow rod body 11 is used to be installed on the curb 100, where the curb 100 refers to the side wall for installing the photoelectric induction mark 2, such as the curb on both sides of the road. A wiring channel 111 is formed in the hollow rod body 11. Usually, the inlet and outlet of the wiring channel 111 are arranged on the hollow rod body 11, for example, the inlet and outlet of the wiring channel 111 are respectively opened at both ends of the hollow rod body 11. The wiring channel 111 is mainly used to pass the wire 21 of the photoelectric induction mark 2, that is, at least part of the wire 21 is accommodated in the wiring channel 111. A first fixing structure 12 and a second fixing structure 13 are fixedly arranged on the hollow rod body 11. As an example, the first fixing structure 12 and the second fixing structure 13 are respectively arranged at both ends of the hollow rod body 11. The first fixing structure 12 and the hollow rod body 11 can be detachably fixed or integrally arranged, and the second fixing structure 13 and the hollow rod body 11 can be detachably fixed or integrally arranged. Among them, the first fixing structure 12 is used to be fixedly connected with the photoelectric induction mark 2, and can be detachably fixed or integrally connected. When using the fixing device 1, the hollow rod body 11 is used to be inserted on the curb 100, for example, inserted in the threading hole of the curb, and the first fixing structure 12 and the second fixing structure 13 are respectively located on both sides of the curb 100. The first fixing structure 12 and the second fixing structure 13 are arranged on the hollow rod body 11. The hollow rod body 11 is used to tighten the first fixing structure 12 and the second fixing structure 13, that is, to pull the first fixing structure 12 and the second fixing structure 13 in opposite directions, so that the first fixing structure 12 and the second fixing structure 13 are respectively against the two side surfaces of the curb 100, so that the first fixing structure 12 and the second fixing structure 13 clamp the curb 100.

[0042] The fixing device 1 provided in the embodiment of the present application sets a hollow rod body 11 as a threading tube to pass the wire 21 of the photoelectric induction mark 2, and passes the wire 21 and the hollow rod body 11 through the same hole on the curb 100 to pass the hollow rod body 11 on the curb 100. The first fixing structure 12 and the second fixing structure 13 are set on the hollow rod body 11. The hollow rod body 11 is used to tighten the first fixing structure 12 and the second fixing structure 13, so that the first fixing structure 12 and the second fixing structure 13 clamp the curb 100, that is, the fixing device 1 is fixed on the curb 100. Since the photoelectric induction mark 2 is fixed on the first fixing structure 12, the photoelectric induction mark 2 is fixed on the curb 100. During the entire installation process, only a single hole needs to be opened on the curb 100, and this hole is used as both a threading hole and a fixing hole, saving the time of opening a hole on the curb 100. At the same time, the first fixing structure 12 and the second fixing structure 13 are tightened by the hollow rod body 11 to clamp and fix the curb 100. This installation method is relatively simple and convenient, and is conducive to further improving the efficiency of installation.

[0043] In addition, most of the assembly work of the above-mentioned fixing device 1 can be completed offline in advance when it is used. When installing the photoelectric induction sign 2 on the road, it is only necessary to pass the hollow rod body 11 through the curb 100, and then make the first fixing structure 12 and the second fixing structure 13 clamp the curb 100 and connect the power. This greatly shortens the time that the installers stay on the road, improves the safety of the installers' operations, and can even be installed without closing the road, thereby reducing the cost of road closure construction and improving economic benefits.

[0044] In some embodiments, at least one of the first fixing structure 12 and the second fixing structure 13 is detachably fixedly connected to the hollow rod body 11. The first fixing structure 12 may be detachably fixedly connected to the hollow rod body 11, or the second fixing structure 13 may be detachably fixedly connected to the hollow rod body 11, or both the first fixing structure 12 and the second fixing structure 13 may be detachably fixedly connected to the hollow rod body 11. Optionally, at least the second fixing structure 13 may be detachably fixedly connected to the hollow rod body 11. In this way, when installing the photoelectric induction mark 2, the second fixing structure 13 may be kept separated from the hollow rod body 11, the first fixing structure 12 is set on one end of the hollow rod body 11, and then the other end of the hollow rod body 11 is passed through the curb 100 until the first fixing structure 12 abuts against the curb 100, and then the second fixing structure 13 is installed on the other end of the hollow rod body 11, so that the first fixing structure 12 and the second fixing structure 13 clamp and fix the curb 100 together. In the above installation process, the photoelectric induction mark 2 can be fixed on the first fixed structure 12 in advance, and the wire 21 of the photoelectric induction mark 2 passes through the wiring channel 111 of the hollow rod body 11, and the first fixed structure 12 is connected to the hollow rod body 11. When working on the road, it is only necessary to pass the hollow rod body 11 from the outside of the curb 100 (such as a curbstone) through the curb 100, and then install the second fixed structure 13 on the inside of the curb 100 and connect it to electricity. This greatly shortens the time that the installer's hands stay on the outside of the curb 100, and can greatly ensure the personal safety of the installer even when working without closing the road. Here, the outside of the curb 100 refers to the side of the curb 100 close to the main road, and vehicles are traveling on the main road. The inside of the curb 100 refers to the side of the curb 100 away from the main road.

[0045] See also Figure 3 In some embodiments, the hollow rod body 11 is a hollow screw. A hollow screw refers to a rod body with a channel formed inside and an external thread provided on the outer surface. The entire outer surface of the hollow screw may be provided with external threads, or part of the outer surface of the hollow screw may be provided with external threads, for example, a first external thread segment and a second external thread segment are respectively provided near the two ends of the hollow screw. The first fixing structure 12 includes a first fixing plate 121, and the first fixing plate 121 is used to fix the photoelectric induction mark 2. Specifically, the first fixing plate 121 is used to fix the back of the photoelectric induction mark 2, which can be clamped, threaded or welded. The first fixing plate 121 is connected to one end of the hollow screw. By connecting the first fixing plate 121 to one end of the hollow screw, and then fixing the photoelectric induction mark 2 on the first fixing plate 121, the photoelectric induction mark 2 is connected to one end of the hollow screw.

[0046] See also Figure 3In some embodiments, the first fixing structure 12 is threadedly connected to the hollow screw. As an example, the first fixing structure 12 only includes a first fixing plate 121, a first through hole 1211 is provided through the middle of the first fixing plate 121, and the first through hole 1211 is a threaded hole with an internal thread, and the first fixing plate 121 is threadedly connected to the hollow screw through the first through hole 1211.

[0047] As an example, the first through hole 1211 in the middle of the first fixing plate 121 is a light hole with a smooth inner wall, the aperture of the first through hole 1211 is slightly larger than the maximum outer diameter of the hollow screw, and the first fixing plate 121 is sleeved on the hollow screw through the first through hole 1211; the first fixing structure 12 also includes a first nut 122, the first nut 122 is used to be threadedly connected with the hollow screw, and the first nut 122 is also used to limit the first fixing plate 121 from being separated from the hollow screw. Optionally, the number of the first nut 122 is one, the first nut 122 is set on the hollow screw, and the first nut 122 is located on the side of the first fixing plate 121 close to the photoelectric induction mark 2, so that when the hollow screw passes through the curb 100, one side of the first fixing plate 121 is against the curb 100, and the other side of the first fixing plate 121 is blocked by the first nut 122, and the first fixing plate 121 will not be separated from the hollow screw. Optionally, there are two first nuts 122, which are respectively located on both sides of the first fixing plate 121. The two first nuts 122 abut against both sides of the first fixing plate 121 and clamp and fix the first fixing plate 121, thereby fixing the first fixing plate 121 on the hollow screw to prevent it from detaching.

[0048] See also Figure 3In some embodiments, a connecting through hole 1212 is provided on the first fixing plate 121, and the connecting through hole 1212 is used to connect with the photoelectric induction mark 2, specifically, connected with the mounting hole 223 on the photoelectric induction mark 2 through a fastener 1213. As an example, the fastener 1213 includes a screw, and the mounting hole 223 is a threaded hole with an internal thread. The screw is sequentially passed through the connecting through hole 1212 and the mounting hole 223, and the screw is threadedly connected with the mounting hole 223, so as to achieve the photoelectric induction mark 2 and the first fixing plate 121 fixedly connected together. As an example, the fastener 1213 includes a bolt and a locking nut. The bolt is sequentially passed through the connecting through hole 1212 and the mounting hole 223 and then connected with the locking nut, so as to achieve the photoelectric induction mark 2 and the first fixing plate 121 locked together. As an example, the fastener 1213 includes a rivet, and the photoelectric induction mark 2 and the first fixing plate 121 are riveted together by the rivet passing through the connecting through hole 1212 and the mounting hole 223 in sequence. By providing a connecting through hole 1212 on the first fixing plate 121, and connecting the connecting through hole 1212 with the mounting hole 223 on the photoelectric induction mark 2, the photoelectric induction mark 2 is fixedly connected to the first fixing plate 121. In the related art, the mounting hole 223 on the photoelectric induction mark 2 is used to connect with the road tooth 100, such as the fixing hole on the curb. Here, the mounting hole 223 is cleverly used to fix the photoelectric induction mark 2 to the first fixing plate 121, so that the fixing device 1 provided in the embodiment of the present application can be used to install the photoelectric induction mark 2 in the related art, expanding the application scope of the fixing device 1. In this way, when installing the photoelectric induction mark 2 on the road, only the fixing device 1 can be provided, and the photoelectric induction mark 2 in the related art can continue to be used, without the need to re-open the mold to manufacture the photoelectric induction mark 2, thereby reducing the cost of road maintenance.

[0049] See also Figure 3 In some embodiments, the connecting through hole 1212 is a waist-shaped hole. Optionally, the extending direction of the waist-shaped hole is consistent with the extending direction of the first fixing plate 121. Since the positions of the mounting holes 223 on different photoelectric induction marks 2 may be different, by setting the connecting through hole 1212 as a waist-shaped hole, the length of the waist-shaped hole is increased compared to the round hole, so that different photoelectric induction marks 2 can be adapted, thereby improving the versatility of the fixing device 1.

[0050] See also Figure 3In some embodiments, the number of the connecting through holes 1212 is multiple, and the multiple connecting through holes 1212 are arranged at intervals on the first fixing plate 121. The photoelectric induction mark 2 is usually provided with two mounting holes 223, and the number of the connecting through holes 1212 is at least two. As an example, the number of the connecting through holes 1212 is 4, and the 4 connecting through holes 1212 are distributed on both sides of the first through hole 1211 in pairs. By providing multiple connecting through holes 1212 on the first fixing plate 121, the adaptability of the fixing device 1 to different photoelectric induction marks 2 can also be improved.

[0051] See also Figure 1 , Figures 3 to 5 In some embodiments, the second fixing structure 13 includes a second fixing sheet 131, and the second fixing sheet 131 and the first fixing sheet 121 are both used to abut against the curb 100 to clamp the curb 100. That is, the first fixing structure 12 abuts against one side surface of the curb 100 with the first fixing sheet 121, and the second fixing structure 13 abuts against the other side surface of the curb 100 with the second fixing sheet 131, and then the first fixing sheet 121 and the second fixing sheet 131 are tightened by a hollow screw so that the second fixing sheet 131 and the first fixing sheet 121 clamp and fix the curb 100. The second fixing plate 131 and the first fixing plate 121 are used to abut against the curb 100, thereby increasing the contact area with the curb 100. On the one hand, when the second fixing plate 131 and the first fixing plate 121 clamp the curb 100, the friction force with the wall surface is increased, and the fixing device 1 is not easy to rotate, thereby improving the stability of the photoelectric induction mark 2; on the other hand, it ensures that the second fixing plate 131 and the first fixing plate 121 are subjected to uniform force to prevent stress concentration, thereby improving the reliability and service life of the fixing device 1.

[0052] In some embodiments, the second fixing structure 13 is threadedly connected to the hollow screw. As an example, the second fixing structure 13 only includes a second fixing plate 131, a second through hole 1311 is provided through the middle of the second fixing plate 131, and the second through hole 1311 is a threaded hole with an internal thread, and the second fixing plate 131 is threadedly connected to the hollow screw through the second through hole 1311.

[0053] As an example, the second through hole 1311 in the middle of the second fixing plate 131 is a light hole with a smooth inner wall, the aperture of the second through hole 1311 is slightly larger than the maximum outer diameter of the hollow screw, and the second fixing plate 131 is sleeved on the hollow screw through the second through hole 1311; the second fixing structure 13 also includes a second nut 132, which is used to be threadedly connected with the hollow screw, and the second nut 132 is also used to limit the second fixing plate 131 from being separated from the hollow screw. Optionally, the number of the second nut 132 is one, and the second nut 132 is set on the hollow screw, and the second nut 132 is located on the side of the second fixing plate 131 away from the photoelectric induction mark 2, so that when the hollow screw passes through the curb 100, one side of the second fixing plate 131 abuts against the curb 100, and the other side of the second fixing plate 131 is stopped by the second nut 132, so that the second fixing plate 131 will not be separated from the hollow screw. Optionally, there are two second nuts 132 , and the two second nuts 132 are located on the same side of the second fixing plate 131 and jointly block the second fixing plate 131 to prevent the second fixing plate 131 from detaching from the hollow screw.

[0054] See also Figure 5 In some embodiments, the second fixing plate 131 includes a fixing plate body 1312 and a flange 1313. The flanges 1313 are located at the two side edges of the fixing plate body 1312. It can be understood that there are two flanges 1313, and both flanges 1313 are bent and extended to the same side of the fixing plate body 1312, so that the cross section of the second fixing plate 131 is U-shaped. Optionally, the fixing plate body 1312 and the flange 1313 are integrally formed. When the fixing device 1 is used, the second fixing plate 131 rests on the curb 100, specifically, the flange 1313 of the second fixing plate 131 rests on the curb 100, and then the second nut 132 is used to press the fixing plate body 1312 on the side of the fixing plate body 1312 away from the flange 1313. Since the cross-section of the second fixing plate 131 is U-shaped, that is, the second fixing plate 131 is arched, the second fixing plate 131, especially when the second fixing plate 131 is a metal part, will undergo elastic deformation, further enhancing the clamping force of the flange 1313 on the curb 100, thereby ensuring the installation stability of the fixing device 1.

[0055] In some embodiments, the second fixing plate 131 has the same structure as the first fixing plate 121. In this way, the same mold or process can be used when preparing the second fixing plate 131 and the first fixing plate 121, which is conducive to reducing the production cost of the product. Optionally, the second fixing plate 131 and the first fixing plate 121 are both metal parts.

[0056] In some other embodiments, the first fixing structure 12 includes an openable and closable clamp, which is used to clamp the photoelectric induction marker 2 to fix it.

[0057] In some other embodiments, the hollow rod body 11 may also be a hollow polished rod (not shown) without threads on the outer surface, and the second fixing structure 13 includes at least two elastic buckles (not shown), which are integrally formed with one end of the hollow polished rod. The elastic buckle includes an elastic arm and an undercut protrusion, one end of the elastic arm is connected to the hollow polished rod, and the undercut protrusion is located at the other end of the elastic arm, and the undercut protrusion is used to stop against the curb 100. As an example, when manufacturing the second fixing structure 13, at least two notches may be opened at one end of the hollow polished rod to form at least two elastic arms, and an undercut protrusion is provided at one end of the elastic arm away from the hollow polished rod. When the fixing device 1 is used, a hole is made on the curb 100, and one end of the hollow rod provided with an elastic buckle is extended into the hole. The elastic arm of the elastic buckle is deformed, and the undercut protrusion abuts against the inner wall of the hole. When the head of the elastic buckle, that is, the undercut protrusion extends out of the hole, the elastic arm is reset, and the undercut protrusion stops abutting against the curb 100. The undercut protrusion cooperates with the first fixing structure 12 to clamp the curb 100 together, thereby fixing the fixing device 1 on the curb 100.

[0058] In order to prove the progressiveness of the embodiment of the present application, an embodiment of the present application provides a fixing device 1, which includes 2 hollow iron sheets, 2 bolts, 5 nuts and 1 hollow screw. The 2 hollow iron sheets are respectively the first fixing sheet 121 and the second fixing sheet 131, the 2 bolts are fasteners 1213, and the 6 nuts are 2 first nuts 122, 1 second nut 132, and 2 locking nuts. Offline, the installer can first use 2 nuts to fix the first hollow iron sheet on one end of the hollow screw, then pass the wire of the photoelectric induction mark 2 through the inside of the hollow screw, and then use 2 bolts and 2 nuts to fix the photoelectric induction mark 2 on the first hollow iron sheet; when working on the road, it is only necessary to pass the hollow screw through the curb, and then pass the second hollow iron sheet and 1 nut on the hollow screw at one time, and rotate the nut to fix the photoelectric induction mark 2 on the curb, and finally connect the power. If the time for drilling is not taken into account, the time for ordinary installers to operate on the road is 30 seconds (skilled installers can do it in 10 seconds); if the time for drilling is taken into account, the time for installers to operate on the road is 3 minutes. The same installer uses the installation method in the relevant technology to install the same photoelectric induction mark 2 on the curb. If the time for drilling is not taken into account, the time for installers to operate on the road is 1 minute; if the time for drilling is taken into account, the time for installers to operate on the road is 10 minutes. By comparison, it can be seen that the above-mentioned fixing device 1 can greatly shorten the time for installing the photoelectric induction mark 2 on the road site. This fixing device 1 is particularly suitable for tunnels, especially tunnels with difficult road closures, small space outside the white line, and large traffic. In addition, the components used in the above-mentioned fixing device 1 can all be purchased, and the overall cost of a single fixing device 1 can be controlled within 3 yuan, which has a high cost performance.

[0059] In the second aspect, the embodiment of the present application further provides a photoelectric induction tag device 3, which includes a photoelectric induction tag 2 and the above-mentioned fixing device 1. The wire 21 of the photoelectric induction tag 2 is arranged in the wiring channel 111, and the photoelectric induction tag 2 is fixedly connected to the first fixing structure 12, which can be an integrated fixed connection or a detachable fixed connection.

[0060] By providing a hollow rod body 11 to pass the wire 21 of the photoelectric induction marker 2, only a single hole needs to be opened on the curb 100 during installation, and this hole is used as both a threading hole and a fixing hole, saving time for opening holes on the curb 100. At the same time, the first fixing structure 12 and the second fixing structure 13 are tightened by the hollow rod body 11 to clamp and fix the curb 100. This installation method is relatively simple and is conducive to further improving the efficiency of installation.

Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
