[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1, with reference to Figures 1 to 5 , which is the first embodiment of the utility model, provides a crossing mechanism that can cross the cable trench and allow the elevated vehicle to pass over it, thereby protecting the cable trench.

[0040] Specifically, it includes a spanning component 100, which includes a spanning frame 101. The spanning frame 101 spans the cable trench to prevent the cable trench from being crushed by an elevated vehicle; support frames 102 are welded downward at both ends of the spanning frame 101, and the support frames 102 support the spanning frame 101. The relationship between the spanning frame 101 and the support frames 102 is similar to that between the main body of a bridge and a pier; a spanning frame panel 109 is welded on the top surface of the spanning frame 101, and the spanning frame panel 109 is similar to the bridge deck; the spanning component 100 as a whole is spanned over the cable trench as a bridge.

[0041] It also includes an extension component 200, which serves as a guiding part at both ends of the crossing component 100 to facilitate the elevated vehicle to cross the component 100 up and down; the extension component 200 includes an extension frame 201, and an extension plate 202 is welded to the extension frame 201; the extension plate 202 includes a first connecting plate 202a, an inclined plate 202b and a second connecting plate 202c, one end of the first connecting plate 202a is connected to the crossing frame panel 109, the second connecting plate 202c is connected to the bottom surface, and the inclined plate 202b is connected between the first connecting plate 202a and the second connecting plate 202c.

[0042] Among them, the crossing frame 101 includes a side beam 101a, which is symmetrically arranged. The two ends of the side beam 101a are respectively extended outward with a connecting end 101a-1. The connecting end 101a-1 is the part of the side beam 101a extending outward from the two ends of the crossing frame panel 109. A first plug hole 105 is opened on the side of the connecting end 101a-1, and the first plug hole 105 is used to fix the extension frame 201.

[0043] The cross section of the extension frame 201 is a right triangle. The vertical side of the extension frame 201 is adjacent to the support frame 102, and the horizontal side of the extension frame 201 is placed on the ground, so that the extension plate 202 on the oblique side of the extension frame 201 transitions from the spanning frame panel 109 to the ground.

[0044] Furthermore, the extension frame 201 includes a top beam 201a, and first matching holes 203 are provided at both ends of the top beam 201a; after the extension component 200 is placed at both ends of the spanning component 100, the first matching holes 203 correspond to the first plug-in holes 105, and the pins are inserted into the first matching holes 203 and the first plug-in holes 105 at the same time, so that the extension component 200 can be fixed to both ends of the spanning component 100. When the elevated vehicle passes over the spanning component 100, it first moves from the extension plate 202 to the spanning frame panel 109, and then moves from the spanning frame panel 109 to the ground through the extension plate 202 at the other end. In this process, due to the fixing effect of the pin, the extension component 200 is prevented from moving.

[0045] Furthermore, the crossing frame 101 also includes a longitudinal beam 101b and a cross beam 101c. The longitudinal beam 101b is arranged between the side beams 101a. In the embodiment of this scheme, the longitudinal beams 101b are preferably set as two, and the cross beams 101c are set as four groups. The cross beams 101c are welded between the side beams 101a and the longitudinal beams 101b, so that the crossing frame 101 is grid-shaped, thereby increasing the compressive strength of the crossing frame 101; and two groups of cross beams 101c are welded to the two ends of the longitudinal beam 101b.

[0046] Guardrails 103 are respectively provided on the side beams 101 a , and the guardrails 103 include a transverse guardrail 103 a , a longitudinal guardrail 103 b and a side guardrail 103 c .

[0047] Among them, the longitudinal protection beam 103b is welded to the two ends of the top surface of the side beam 101a near the connecting end 101a-1, the transverse protection beam 103a is welded between the top surfaces of the longitudinal protection beam 103b, and the side protection beam 103c is welded between the longitudinal protection beam 103b and the connecting end 101a-1. The side protection beam 103c prevents the elevated vehicle from colliding with the guardrail 103 when moving to the crossing frame 101, and at the same time improves the connection strength between the guardrail 103 and the side beam 101a.

[0048] Preferably, the support frame 102 includes a vertical support beam 102a, a connecting beam 102b and a side support beam 102c.

[0049] Among them, in this embodiment, there are four vertical support beams 102a, which are welded at equal intervals to the bottom surface of the cross beam 101c at the end of the spanning frame 101, the connecting cross beam 102b is welded to the bottom surface of the vertical support beam 102a, and the side support beam 102c is welded between the connecting cross beam 102b and the side beam 101a.

[0050] It should be noted that, in this embodiment, the spanning frame 101, the support frame 102 and the guardrail 103 are respectively made of steel pipes. Other materials that can achieve the purpose of this device can also be used, and the specific material selection is not limited here.

[0051] Example 2, reference Figures 4 to 7 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides an elevated vehicle device, which solves the problem of the inconvenience of moving the elevated vehicle device, including the crossing mechanism in the above embodiment.

[0052] Specifically, the moving component 300 includes a driving wheel assembly 301 and a driven wheel assembly 302 respectively fixedly connected to two ends of the spanning frame 101 .

[0053] Specifically, the driving wheel assembly 301 includes a driving wheel 301 a and a driving wheel connecting plate 301 c ; the driving wheel 301 a is hinged to the driving wheel connecting plate 301 c , and the driving wheel connecting plate 301 c is detachably connected to the crossing frame 101 .

[0054] A first driving wheel matching hole 301d and a second driving wheel matching hole 301e are provided on the driving wheel connecting plate 301c. The centers of the first driving wheel matching hole 301d and the second driving wheel matching hole 301e are located on the same horizontal line.

[0055] The driving wheel assembly 301 also includes a motor 301b, which is a remote-controlled motor electrically connected to the driving wheel 301a. The operator controls the motor via a remote control to drive the driving wheel 301a to move, turn, and stop. The motor and remote control can be selected from suitable models available in the art.

[0056] The driven wheel assembly 302 includes a driven wheel 302a and a driven wheel connecting plate 302b; the driven wheel 302a is hinged to the driven wheel connecting plate 302b, and the driven wheel connecting plate 302b is detachably connected to the crossing frame 101.

[0057] A first master-slave wheel matching hole 302c and a second driven wheel matching hole 302d are provided on the driven wheel connecting plate 302b. The centers of the first master-slave wheel matching hole 302c and the second driven wheel matching hole 302d are located on the same horizontal line.

[0058] Furthermore, a second plug-in hole 106, a first plug-in fitting hole 107 and a second plug-in fitting hole 108 are respectively provided on the connecting ends 101a-1 at both ends of the side beam (101a), and the second plug-in fitting hole 106, the first plug-in fitting hole 107 and the second plug-in fitting hole 108 at both ends are symmetrically arranged; the centers of the first plug-in fitting hole 107 and the second plug-in fitting hole 106 are located on the same horizontal line, the second plug-in fitting hole 108 is located on the lower side of the second plug-in hole 106, and the centers of the second plug-in fitting hole 108 and the second plug-in fitting hole 106 are located on the same vertical line.

[0059] The second driving wheel matching hole 301e corresponds to the second plugging hole 106. After the pins are inserted into both holes at the same time, the driving wheel connecting plate 301c is hinged to the side beam 101a through the pins.

[0060] Specifically, when the driving wheel assembly 301 is in the first position, that is, the position where the driving wheel 301a contacts the ground, the first driving wheel matching hole 301d corresponds to the first plug-in matching hole 107, and the pin 104 is inserted into the first driving wheel matching hole 301d and the first plug-in matching hole 107, so that the driving wheel assembly 301 is fixed in the first position; when the driving wheel assembly 301 is in the second position, that is, the driving wheel 301a is separated from the ground, the first driving wheel matching hole 301d is rotated to match the second plug-in matching hole 108, and the pin 104 is inserted into the first driving wheel matching hole 301d and the second plug-in matching hole 108, so that the driving wheel assembly 301 is fixed in the second position.

[0061] The first driven wheel matching hole 302c corresponds to the second plugging hole 106. After the pins are inserted into both holes at the same time, the driven wheel connecting plate 302b is hinged to the side beam 101a through the pins.

[0062] When the driven wheel assembly 302 is in the first position, that is, the driven wheel 302a is in contact with the ground, the second driven wheel mating hole 302d corresponds to the first plug-in mating hole 107, and the pin 104 is inserted into the second driven wheel mating hole 302d and the first plug-in mating hole 107 to fix the driven wheel assembly 302 in the first position; when the driven wheel assembly 302 is in the second position, that is, the driven wheel 302a is separated from the ground, the second driven wheel mating hole 302d is rotated to match the second plug-in mating hole 108, and the pin 104 is inserted into the second driven wheel mating hole 302d and the second plug-in mating hole 108 to fix the driven wheel assembly 302 in the second position.

[0063] When in use, first, the spanning component 100 is moved to a designated position, for example, spanning across both sides of a cable trench, and the driving wheel assembly 301 and the driven wheel assembly 302 are simultaneously fixed in the first position. When the driving wheel assembly 301 and the driven wheel assembly 302 are simultaneously in the first position, the spanning component 100 is completely lifted off the ground by the driving wheel 301a and the driven wheel 302a, so that the moving component 300 drives the spanning component 100 to move; the motor is turned on, and the remote control controls the driving wheel to operate. After reaching the designated position, the motor is turned off;

[0064] Second, pull out the latch 104 that secures the driving wheel connecting plate 301c and the driven wheel connecting plate 302b, move the driving wheel connecting plate 301c and the driven wheel connecting plate 302b to the second position, and then secure them with the latch 104;

[0065] Third, install the extension member 200. Before use, place the extension member 200 on the spanning frame panel 109. When in use, remove the extension member 200 and place the vertical surface of the extension member 200 adjacent to the vertical support beam 102a, so that the first matching hole 203 corresponds to the first plug hole 105. Then, insert the pin 104 into the first matching hole 203 and the first plug hole 105 at the same time to securely connect the extension member 200 to the spanning member 100. To facilitate the operation of the elevated vehicle, the extension members 200 are respectively provided at both ends of the spanning member 100.

[0066] Finally, after the elevated vehicle passes, the extension component 200 is removed, the driving wheel connecting plate 301c and the driven wheel connecting plate 302b are restored to the first position, and the motor is started to move the crossing component 100 to the parking point.

[0067] The rest of the structure is the same as that of Example 1.

[0068] In summary, the device enables the driving wheel 301a and the driven wheel 302a to be freely switched between two positions through the setting of the first plug-in fitting hole 107 and the second plug-in fitting hole 108, which not only facilitates the movement of the entire device, but also avoids the problem that the driving wheel 301a and the driven wheel 302a are easily damaged when the overhead vehicle passes through the device if the driving wheel 301a and the driven wheel 302a provide support and force.

[0069] Example 3, reference Figure 1 、 5 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a different setting position of the second plug-in fitting hole 108, which solves the problem of assembling the driven wheel assembly.

[0070] Specifically, the second plug-in fitting hole 108 may also be provided on the side support beam 102c to accommodate different sizes of driven wheels.

[0071] In this embodiment, the driven wheel is configured as a universal wheel, and the outer diameter of the existing universal wheel is smaller than that of the driving wheel. In order to keep the driven wheel and the driving wheel in the same plane during movement, the assembly position of the driven wheel should be lower than the assembly position of the driving wheel. When the driven wheel is converted from the first position to the second position, due to space limitations, it is necessary to open a second plug-in fitting hole 108 on the side support beam 102c to improve the adaptability of rollers of different sizes to the device.
