Specific embodiments
[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] As Figures 1-5 shown, an assembled maintenance railing for road engineering provided by an embodiment of the present utility model includes a railing unit one 1, a railing unit two 2, and a splicing component 3 between the railing unit one 1 and the railing unit two 2. The railing unit one 1 includes a fixed vertical rod 11 and a movable vertical rod 12. A guide sleeve 13 is provided at the top of the fixed vertical rod 11, and a guide rod 14 inserted into the inside of the guide sleeve 13 is provided at the top of the movable vertical rod 12. A threaded sleeve 15 is fixedly provided in the middle of the outer wall of one side of the fixed vertical rod 11, and a lead screw 16 threadedly inserted into the inside of the threaded sleeve 15 is provided in the middle of the outer wall of one side of the movable vertical rod 12. A rotating component is provided between one end of the lead screw 16 and the movable vertical rod 12.
[0025] Specifically, in this embodiment, it includes railing unit 1, railing unit 2, and a splicing component 3 between railing unit 1 and railing unit 2. The structures of railing unit 1 and railing unit 2 are the same, and railing unit 1 and railing unit 2 are connected end to end. Through an orderly and rapid splicing method, the efficiency of railing splicing is improved. Railing unit 1 includes a fixed vertical rod 11 and a movable vertical rod 12. A guide sleeve 13 is provided at the top of the fixed vertical rod 11, and a guide rod 14 inserted into the inside of the guide sleeve 13 is provided at the top of the movable vertical rod 12. When adjusting the size of the railing, the guide rod 14 slides freely inside the guide sleeve 13. A threaded sleeve 15 is fixedly provided in the middle of the outer wall on one side of the fixed vertical rod 11, and a lead screw 16 threadedly inserted into the inside of the threaded sleeve 15 is provided in the middle of the outer wall on one side of the movable vertical rod 12. A rotating component is provided between one end of the lead screw 16 and the movable vertical rod 12. By controlling the rotation of the rotating component, the operator can drive the lead screw 16 to rotate. The lead screw 16 rotates inside the threaded sleeve 15, so that the movable vertical rod 12 slides linearly along the fixed vertical rod 11, realizing the adjustment of the size of the railing.
[0026] An assembled maintenance railing for road engineering provided by the present utility model adopts the splicing component 3, which can quickly achieve the disassembly and assembly effect between adjacent two railing units, facilitating people to use the maintenance railing for road engineering, being more convenient and efficient, and thus reducing the trouble of people when splicing the railing.
[0027] As an embodiment provided by the present utility model, bases 17 are fixedly provided on the outer walls of the bottoms of the fixed vertical rod 11 and the movable vertical rod 12, and a water injection nozzle 18 is provided on the outer wall of one side of the top of the base 17. The base 17 is a hollow cavity structure. After the operator finishes splicing the railing, clear water can be injected into the inside of the base 17 through a water pipe and the water injection nozzle 18, thus ensuring the stability of the railing placement.
[0028] As another embodiment provided by the present utility model, the rotating component includes a bearing sleeve 165 fixed on the movable vertical rod 12, and a smooth shaft 161 is rotatably inserted into the inside of the bearing sleeve 165. Retaining rings 162 and elastic clips 163 are sleeved on both outer sides of the smooth shaft 161. The smooth shaft 161 is limited inside the bearing sleeve 165 through the retaining ring 162, and the stability of the retaining ring 162 on the outside of the smooth shaft 161 is achieved through the elastic clip 163. One end of the smooth shaft 161 is fixedly connected to one end of the lead screw 16, and an operating head 164 is provided at the end of the smooth shaft 161 away from the lead screw 16. By controlling the rotation of the operating head 164, the rotation of the lead screw 16 is driven by the smooth shaft 161.
[0029] As yet another embodiment provided by the present utility model, a detachable operating tool 4 is provided at one end of the lead screw 16. The operating tool 4 includes a base plate 41, and a socket 42 is provided on an outer wall of one side of the base plate 41. A plurality of handles 43 are welded on the outer wall of the base plate 41 and are distributed in an equidistant circular pattern. An operator can use the operating tool 4 to rotate the lead screw 16. Specifically, the operator holds the handle 43, inserts the socket 42 onto the operating head 164 of the optical axis 161, and then holds the handle 43 to drive the base plate 41 to rotate. Thus, by the rotation of the optical axis 161 inside the bearing sleeve 165, the rotation of the lead screw 16 inside the threaded sleeve 15 is realized, so as to adjust the size of the railing monomer. At the same time, the operator can also use an electric tool to drive the lead screw 16 to rotate. At this time, only the sleeve corresponding to the operating head 164 needs to be replaced;
[0030] The specifications of the operating head 164 and the socket 42 are adapted to each other, and the operating head 164 has a three-sided structure. The adopted three-sided structure is to avoid common tools in the prior art and prevent external personnel from randomly damaging the railing.
[0031] As yet another embodiment provided by the present utility model, the splicing assembly 3 includes limiting disks 33 fixed on the fixed vertical rod 11 and the movable vertical rod 12. The limiting disks 33 are fixed on the fixed vertical rod 11 and the movable vertical rod 12, which can prevent the rod sleeve 34 from falling. Rod sleeves 34 are sleeved outside both the fixed vertical rod 11 and the movable vertical rod 12 and are located above the limiting disks 33. Mortise heads 31 and limiting sleeves 32 are respectively fixed on the outer parts of the rod sleeves 34 on the fixed vertical rod 11 and the movable vertical rod 12. The mortise head 31 is slidably inserted into the limiting sleeve 32. Elastic pins 35 are provided on both sides of one end of the mortise head 31, and pressing caps 36 are provided on both sides of the limiting sleeve 32. When an operator splices adjacent railings, the mortise head 31 can be inserted into the limiting sleeve 32. At this time, the elastic pins 35 are squeezed and retracted, so that the mortise head 31 can be easily inserted into the limiting sleeve 32. After being inserted into the limiting sleeve 32 to a certain depth, the elastic pins 35 pop out at the positioning holes of the limiting sleeve 32. The above-mentioned pressing caps 36 are of an elastic structure. When people want to disassemble the splicing assembly 3, the operator can use two fingers to squeeze the pressing caps 36, so that the elastic pins 35 retract from the inside of the positioning holes. At this time, the operator can easily pull out the mortise head 31 from the inside of the limiting sleeve 32 to realize the rapid disassembly of the splicing assembly.
[0032] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above-mentioned drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
