Technical Field

[0001] The invention relates to the field of signal towers, in particular to a portable signal tower. Background Art

[0002] At present, communication towers are widely used in the fields of power, communication, broadcasting, and television signal lights for wireless signal transmission. Signal towers are generally fixed and simple in structure, but due to their large size, installation is very difficult and they are generally used as long-term signal towers.

[0003] When various activities are held, the signal demand has exceeded the signal output of the existing signal tower, so it is generally necessary to install a temporary signal tower to transmit sufficient signals. Such temporary signal towers are generally fixed on signal vehicles so that they can be moved at any time. However, the signal towers on existing signal vehicles are generally fixed, and their overall height is relatively high. When it is necessary to pass through tunnels or other roads with obstacles above to reach the destination, it is necessary to take a detour or even fail to reach the destination, which greatly affects the use. Summary of the invention

The vehicle body includes a head portion at the front end and a bearing portion at the rear end.

[0032] like Figure 1-9 As shown, the portable signal tower is described in detail:

[0033] A portable signal tower includes a vehicle body capable of carrying a signal station 601 for movement. The vehicle body includes a head portion 101 at the front end and a bearing portion 102 at the rear end. A conversion frame is connected to the bearing portion 102 for supporting the signal station 601 to a higher position to increase signal strength, or for folding the signal station 601 to the bearing portion 102 for easy carrying and movement of the vehicle body.

[0034] The high and low position conversion of the signal station 601 is formed by the conversion frame, thereby facilitating the use of increased signal strength at a high place, and at the same time, facilitating movement at a low place through a tunnel or other roads with overhead obstacles.

[0035] like Figure 1-9 As shown:

[0036] The conversion frame includes two vertical columns 104 fixed on the bearing part 102, a horizontal axis I202 is provided between the two vertical columns 104, and a track frame 103 fixed on the bearing part 102 in the front and rear directions, a mobile frame 301 is slid on the track frame 103, a horizontal axis II302 is fixed on the upper end of the mobile frame 301, long hole side plates 401 are rotatably provided at both ends of the horizontal axis II302, long holes are penetrated on the two long hole side plates 401, and the two long hole sleeves are slid on the horizontal axis I202, and the signal station 601 is located between the two long hole side plates 401 and away from the end of the horizontal axis II302.

[0037] A screw rod Ⅰ303 is rotatably disposed on the track frame 103 , and the screw rod Ⅰ303 is threadedly connected to the moving frame 301 .

[0038] By rotating the screw rod Ⅰ303, the screw rod Ⅰ303 thread-driven moving frame 301 slides back and forth on the track frame 103, and then the long hole side plate 401 passes through the long hole and rotates around the horizontal axis Ⅰ202, so that the long hole side plate 401 is converted between a horizontal or vertical state, that is, when it is horizontal, the signal station 601 is located at a low place, and when it is vertical, the signal station 601 is located at a high place.

[0039] like Figure 1-9 As shown:

[0040] A lifting frame 201 is provided on the two vertical columns 104 for lifting and limiting sliding, and a horizontal axis I 202 is fixed on the lifting frame 201 . A screw rod II 203 is provided at the front end of the bearing part 102 for vertical rotation, and the screw rod II 203 is threadedly connected with the lifting frame 201 .

[0041] By rotating the screw rod II 203, the lifting frame 201 can be threadedly driven to move up and down on the two vertical columns 104, thereby adjusting the horizontal height of the horizontal axis I 202. When the horizontal axis I 202 is at the highest point, space is provided for the moving frame 301 to move to the bottom of the horizontal axis I 202, thereby making the long hole side plate 401 upright. When the horizontal axis I 202 is at the lowest point, it is convenient to cooperate with the inclined long hole side plate 401 to transform into a horizontal state, thereby making the signal station 601 at the lowest point.

[0042] like Figure 1-9 As shown:

[0043] A gantry 402 is fixed on the two long hole side plates 401, a slide groove 403 is arranged inside the gantry 402, an inner bracket 405 slides in the two slide grooves 403, a screw rod III 404 rotates on the gantry 402, the screw rod III 404 is threadedly connected to the inner bracket 405, and the signal station 601 moves with the inner bracket 405.

[0044] By rotating the screw III 404, the inner bracket 405 can be threadedly driven to slide in the gantry 402. When the long hole side plate 401 is in the erected state, the gantry 402 is also in this state. At this time, the inner bracket 405 slides in the gantry 402, thereby increasing the overall length of the inner bracket 405 and the gantry 402, so that the signal station 601 can be further raised, and the signal strength can be further increased.

[0045] At the same time, by switching the state of the long hole side plate 401 and sliding the inner bracket 405 in the gantry 402, the height of the signal station 601 is adjusted, so that the height of the signal station 601 can adapt to different environments and reach the highest point of the environment.

[0046] like Figure 1-9 As shown:

[0047] The inner bracket 405 has two pins 502 for rotation at the end away from the moving bracket 301 , a U-shaped bracket 501 is fixed between the two pins 502 , and the signal station 601 is located in the U-shaped bracket 501 .

[0048] The U-shaped frame 501 is rotatably connected to the inner bracket 405 through two pin shafts 502, so that when the inner bracket 405 changes different states with the long hole side plate 401, it can always ensure that the opening direction of the U-shaped frame 501 is upward, ensuring that the signal station 601 in the U-shaped frame 501 is in an upright state for operation;

[0049] Furthermore, by providing a counterweight block at the lower end of the U-shaped frame 501, it can be further ensured that the U-shaped frame 501 is always in a state where the opening direction is facing upward.

[0050] like Figure 1-9 As shown:

[0051] A double-headed motor 503 is installed in the middle of the U-shaped frame 501, and screw rods IV504 are fixed at both ends of the double-headed motor 503. Moving blocks 604 are threadedly connected to the two screw rods IV504. Two sliding rods 505 are fixed in the U-shaped frame 501, and a seat plate 602 slides through the two sliding rods 505. Two interlocking plates 603 rotate between both ends of the seat plate 602 and the two moving blocks 604, and the signal station 601 is fixed on the seat plate 602.

[0052] The two screw rods IV 504 are driven to rotate simultaneously by the double-headed motor 503, so that the two moving blocks 604 are synchronously moved closer or farther away. Then, when the two moving blocks 604 are synchronously moved closer, the four interlocking plates 603 are used to make the seat plate 602 slide upward on the two slide bars 505, so that the signal station 601 is raised in the U-shaped frame 501, increasing the height of the signal station 601 while preventing the side panels of the U-shaped frame 501 from blocking the signal of the signal station 601.

[0053] Further:

[0054] Rollers 304 are rotatably disposed at the four corners of the moving frame 301 , and the rollers 304 roll in the track frame 103 , so that the moving frame 301 can be easily moved in the track frame 103 .

[0055] like Figure 1-9 As shown:

[0056] Furthermore, by setting the highest point of the conversion frame and the signal station 601 to be lower than the highest point of the head 101 when the signal station 601 is folded to the lowest position on the conversion frame, it is more convenient for the vehicle body to move on the road based on its own size; at the same time, in order to avoid interference between the movement of the signal station 601 and the head 101 when the signal station 601 is raised, the horizontal axis I 202 should be raised first to make the signal station 601 higher than the head 101, and then the portal frame 402 should be converted to an upright state, so as to achieve the purpose of freely converting the high and low positions of the signal station 601.
