DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] In environments such as tunnels, the guide rails are generally laid by laying multiple guide rail segments on the tunnel wall and installing them on the tunnel wall through fixed connections such as bolts. In this way, it is difficult to disassemble the guide rail segments. However, by using a guide rail connecting device to connect a preset guide rail segment between two fixed guide rail segments, the preset guide rail segment can eliminate fixed connections such as bolts, thereby facilitating the installation and disassembly of the preset guide rail segment.

[0031] See also Figure 1-2 , which is a schematic structural diagram of a guide rail 200 provided in an embodiment of the present invention. The guide rail 200 can be installed, for example, on the inner wall of a tunnel, and includes a fixed guide rail segment 210, a movable guide rail segment 220, and a guide rail connecting device 100. The fixed guide rail segment 210 is fixedly connected to the inner wall of the tunnel; the movable guide rail segment 220 is not connected to the inner wall of the tunnel and is connected to the fixed guide rail segment 210 via the guide rail connecting device 100. Furthermore, the cross-sections of the fixed guide rail segment 210 and the movable guide rail segment 220 are identical, so the end faces of the fixed guide rail segment 210 and the movable guide rail segment 220 can be smoothly connected after splicing.

[0032] Preferably, see Figure 3-4 The movable guide rail segment 220 includes, for example, a running side 224 and a mounting side 225. The running side 224 and the mounting side 225 are two parallel surfaces. The fixed guide rail segment 210 is configured in the same manner as the movable guide rail segment 220. The side surface between the running side 224 and the mounting side 225 of the movable guide rail segment 220 is provided with, for example, a first opening 221. The mounting side 225 of the movable guide rail segment 220 is provided with, for example, a positioning member mounting hole 211, a limiting member through-hole 222, and a drive unit 170 mounting hole 223. The mounting side 225 of the movable mounting unit 110 is also provided with a positioning member mounting hole 211. For example, the positioning member mounting holes 211 can be a plurality of waist holes parallel to the end surface; the limiting member through-hole 222 can be a waist hole perpendicular to the end surface and located between the positioning member mounting hole 211 and the drive unit mounting hole 223; the drive unit mounting hole 223 can be a square slot having a width close to the width of the side surface.

[0033] Furthermore, both the fixed guide rail segment 210 and the movable guide rail segment 220 are provided with an installation space 226 , which is located between the walking side 224 and the installation side 225 .

[0034] Preferably, see Figure 5 , which is a schematic structural diagram of a guide rail connection device 100 provided in an embodiment of the present invention. The guide rail connection device 100 includes: a movable mounting portion 110, a fixed mounting portion 120, a slider 130, a crank 140, a rotating portion 150, a limiting assembly 160, a driving portion 170, and an operating portion 180.

[0035] Specifically, the fixed mounting portion 120, slider 130, crank 140, rotating portion 150, and operating portion 180 are located within the mounting space 226 of the movable guide rail section; the movable mounting portion 110 is located within the mounting space 226 of the fixed guide rail section. The structure of the movable mounting portion 110 is identical to that of the fixed mounting portion 120; one end of the slider 130 can be inserted from the fixed mounting portion 120 into the movable mounting portion 110, while the other end of the slider 130, opposite to the fixed mounting portion 120, is connected to the crank 140; the end of the crank 140, away from the slider 130, is connected to the rotating portion 150 for transmitting power to the slider 130.

[0036] The limiting assembly 160 is connected to the slider 130 and is located between the fixed mounting portion 120 and the crank 140, for limiting the range of motion of the slider 130; the driving portion 170 is axially connected to the rotating portion 150 for providing power; the operating portion 180 is connected to the rotating portion 150 for manual operation.

[0037] Preferably, see Figure 6-7 , which is a structural schematic diagram and exploded view of the movable mounting part 110 and the fixed mounting part 120. Among them, the movable mounting part 110 is also provided with, for example, a first mounting hole 111 and a first sleeve 112. The first mounting hole 111 extends from the side of the movable mounting part 110 facing the fixed mounting part 120 to the side of the movable mounting part 110 away from the fixed mounting part 120. The first sleeve 112 is located in the first mounting hole 111, and the outer wall of the first sleeve 112 cooperates with the inner wall of the first mounting hole 111. In addition, a flange is provided at one end of the first sleeve 112 facing the fixed mounting part 120, which is used for fixed connection between the first sleeve 112 and the movable mounting part 110. For example, four countersunk holes are circumferentially distributed on one side of the flange facing the fixed mounting part 120, and four threaded holes are provided at corresponding positions of the movable mounting part 110, and the countersunk holes and the threaded holes are connected by bolts. Obviously, after the flange is connected to the movable mounting portion 110 , it sinks into the movable mounting portion 110 , that is, the side of the flange facing the fixed mounting portion 120 is substantially flush with the side of the movable mounting portion 110 facing the fixed mounting portion 120 .

[0038] Furthermore, the movable mounting portion 110 is also provided with a first positioning member 113, which is located on the side of the movable mounting portion 110 facing the mounting side 225 of the fixed guide rail segment 210, and the mounting side 225 of the fixed guide rail segment 210 is clamped between the movable mounting portion 110 and the first positioning member 113. For example, the first positioning member 113 can be a rectangular thin sheet, with both ends extending out of the movable mounting portion 110, and a waist hole is provided at both ends, which is connected to the mounting side 225 of the fixed guide rail segment 210 by bolts and nuts to achieve positioning. Obviously, the first positioning member 113 is provided with a protrusion on the side facing the movable mounting portion 110, and the movable mounting portion 110 is provided with a mounting groove at a position corresponding to the protrusion, corresponding to the positioning member mounting hole 211 of the fixed guide rail segment 210, and the protrusion passes through the positioning member mounting hole 211 and is engaged with the mounting groove to complete the matching fixation of the movable mounting portion 110 and the fixed guide rail segment 210.

[0039] Similarly, the fixed mounting portion 120 is equipped with a second sleeve 122, a second mounting hole 121, and a second positioning member 123 of the same size and structure as the movable mounting portion 110. The installation relationship between the second sleeve 122, the second mounting hole 121, and the second positioning member 123 is the same as that of the movable mounting portion 110 and will not be repeated here. The fixed mounting portion 120 and the movable mounting portion 110 are arranged opposite each other, that is, the flange of the second sleeve 122 faces the flange of the first sleeve 112, and the second sleeve 122 and the first sleeve 112 are concentric.

[0040] Furthermore, the slider 130 can be a smooth round rod, with a first end inserted into the second sleeve 122. When the slider 130 slides toward the movable mounting portion 110, the first end enters the first sleeve 112, vertically securing the fixed mounting portion 120 and the movable mounting portion 110. The first end can be chamfered to form a conical shape, preventing friction between the first end and the inner wall of the second sleeve 122 and damaging the second sleeve 122.

[0041] Preferably, see Figure 8 , which is a schematic diagram of the structure of the limit assembly 160. The limit assembly 160 includes: a first limit member 161, a second limit member 162, a third limit member 163, a first limit mounting plate 164, and a second limit mounting plate 165. For example, the first limit member 161 is connected to the slider 130 and is located between the second limit member 162 and the third limit member 163; the second limit member 162 is mounted on the first limit mounting plate 164, and the third limit member 163 is mounted on the second limit mounting plate 165, with the second limit member 162 and the third limit member 163 being arranged opposite each other; and the first limit mounting plate 164 and the second limit mounting plate 165 are arranged on the same horizontal plane.

[0042] Furthermore, the first stopper 161 can be a thin plate, arranged parallel to the length of the slider 130. A stopper mounting position 131 is provided at the position of the slider 130 corresponding to the first stopper 161, and the thin plate is embedded in the stopper mounting position 131 for fixation. Furthermore, the first stopper mounting plate 164 and the second stopper mounting plate 165 further define a stopper working space 166. The first stopper 161 moves within the stopper working space 166, and the range of motion of the first stopper 161 can be varied by adjusting the distance between the first stopper mounting plate 164 and the second stopper mounting plate 165.

[0043] Furthermore, the first position-limiting mounting plate 164 and the second position-limiting mounting plate 165 can be disposed on the mounting side 225 of the movable guide rail segment 220. That is, the mounting side 225 of the movable guide rail segment 220 is sandwiched between the first position-limiting mounting plate 164 and the slider 130. Accordingly, the position of the first position-limiting member 161 corresponds to the position-limiting member through-hole 222 on the mounting side 225. The length of the position-limiting member through-hole 222 is greater than the length of the position-limiting member working space 166. This prevents the position-limiting member through-hole 222 from restricting the range of motion of the first position-limiting member 161 when the distance between the first position-limiting mounting plate 164 and the second position-limiting mounting plate 165 is increased. In addition, multiple through holes can be set on the first limiting mounting plate 164 and the second limiting mounting plate 165 for connecting the movable guide rail section 220, preferably four through holes, two of which are located at the two corners of the first limiting mounting plate 164 away from the second limiting mounting plate 165, and the other two through holes are located at the two corners of the second limiting mounting plate 165 away from the first limiting mounting plate 164.

[0044] Preferably, the second limiter 162 and the third limiter 163 may be photoelectric switches, each of which has a sensing end. The sensing end of the second limiter 162 faces the sensing end of the third limiter 163, and the sensing ends of the second limiter 162 and the third limiter 163 are respectively located at opposite ends of the limiter working space 166. When the first limiter 161 moves to the sensing end of either photoelectric switch, the movement of the slider 130 is stopped. Compared to other collision-based limiter methods, the use of photoelectric switches can reduce unnecessary friction and damage, thereby extending the service life.

[0045] Preferably, see Figure 9-11 The two ends of the crank 140 are movably connected to the slider 130 and the rotating part 150. For example, the end of the slider 130 connected to the crank 140 is designed to have two parallel planes. A through hole is provided in the plane, and a through hole is also provided at a corresponding position of the crank 140. A rod passes through the through hole to connect the slider 130 and the crank 140.

[0046] Preferably, the rotating portion 150 can be a disk, and the crank 140 can be connected to the side of the rotating portion 150 close to the driving portion 170 or the side of the rotating portion 150 away from the driving portion 170, preferably the side of the rotating portion 150 close to the driving portion 170. Correspondingly, the crank 140 is also connected to the side of the slider 130 close to the driving portion 170. In addition, the connection method of the crank 140 and the rotating portion 150 is the same as the connection method of the crank 140 and the slider 130, and will not be repeated here.

[0047] Preferably, the driving part 170 includes, for example, a motor 173, a driving part mounting plate 172 and an output shaft 171. The driving part mounting plate 172 may be a square plate with a through hole for the output shaft 171 provided in the center. One end of the output shaft 171 is connected to the motor 173, and the other end of the output shaft 171 away from the motor 173 is provided with a keyway. For example, the motor 173 is mounted on the driving part mounting plate 172, and the other end of the output shaft 171 away from the motor 173 passes through the through hole of the output shaft 171 and is connected to the rotating part 150. Accordingly, an axial hole and a keyway are provided in the center of the rotating part 150. The output shaft 171 is inserted into the axial hole and fixed to the rotating part 150 by a flat key, so that the motor 173 can drive the rotating part 150 to rotate.

[0048] Furthermore, the drive unit mounting plate 172 may be provided with multiple through-holes circumferentially. For example, four through-holes may be provided based on the parameters of the motor 173 for securing the motor 173. Additionally, four through-holes may be provided at the four corners away from the output shaft 171 for securing the drive unit mounting plate 172 to the running surface of the movable guide rail segment 220. The running surface is sandwiched between the drive unit mounting plate 172 and the rotating unit 150.

[0049] Preferably, the rotating part 150 is connected to the operating part 180 on the side, and the rotating part 150 can be a straight rod. For example, the rotating part 150 and the operating part 180 are fixedly connected, and the connection point between the rotating part 150 and the operating part 180 and the connection point between the rotating part 150 and the crank 140 are located in the same direction of the rotating part 150, that is, the end of the crank 140 connected to the rotating part 150 rotates as the operating part 180 rotates. The function of the operating part 180 is that when the motor 173 is not working, the operating part 180 can be manually rotated to drive the rotating part 150, the crank 140 and the slider 130 to move. When the operating part 180 is perpendicular to the slider 130, the operating part 180 extends out of the movable guide rail section 220 through the first opening 221 of the movable guide rail section 220, which is convenient for direct manual operation.

[0050] Preferably, see Figure 12, which is a bottom view of the guide rail connecting device 100. The working method of the guide rail connecting device 100 is as follows: when the operating part 180 is perpendicular to the slider 130, the end of the slider 130 away from the crank 140 is located in the fixed mounting part 120, and the first limit member 161 is located in the third limit member 163. At this time, the fixed guide rail segment 210 and the movable guide rail segment 220 are separated; the motor 173 is working, the output shaft 171 drives the rotating part 150 to rotate counterclockwise, and the crank 140 pushes the slider 130 to move toward the movable mounting part 110 until the first limit member 161 is located in the second limit member 162. The second limit member 162 receives a signal to stop the motor 173. At this time, the end of the slider 130 away from the crank 140 is located in the movable mounting part 110, and the connection and fixation of the fixed guide rail segment 210 and the movable guide rail segment 220 are achieved. On the contrary, the motor 173 reverses, the rotating part 150 rotates clockwise, and the crank 140 pulls the slider 130 back until the first limit member 161 returns to the third limit member 163. The third limit member 163 receives a signal to stop the motor 173. At this time, the end of the slider 130 away from the crank 140 is located in the fixed mounting part 120, that is, the fixed guide rail section 210 and the movable guide rail section 220 are separated.

[0051] When the driving part 170 is not present, the above-mentioned effects can also be achieved by operating the operating part 180 to drive the rotating part 150 to rotate, which will not be described in detail here.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
