[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example

[0040] See Figure 1-10 The present invention provides the following technical solution: a convenient measuring station moving support for shield tunnels, comprising: a first support 1, a second support 2, a support plate 3 and a first support rod 4, wherein the two sides of the second support 2 overlap with the sides of the first support 1 and the support plate 3 respectively, and the first support 1 is movably connected to the support plate 3;

[0041] See Figure 1 , Figure 2 , Figure 4 and Figure 7 The first bracket 1 includes a first fixing plate 100. The side of the first fixing plate 100 is provided with a first through hole 101 and a second through hole 103. The first through hole 101 is fixedly connected to the first support rod 4 through a ball connector 102. The second through hole 103 is fixedly connected to the third support rod 6 through a first pin 104.

[0042] A spherical connector 102 and a first pin 104 are provided inside the first bracket 1 to connect the support rod. The spherical connector 102 allows the operator to rotate the position of the first support rod 4 at multiple angles, improving the practicality of the first support rod 4 and making it easier to fix the support plate 3, thus facilitating the operator's use.

[0043] See Figure 1 , Figure 2 and Figure 3 The second bracket 2 includes a second fixing plate 200. The side of the second fixing plate 200 is provided with a third through hole 201 and a groove 203. A second support rod 5 is fixedly connected in the third through hole 201 by a second pin 202. A placement plate 205 is fixedly connected in the groove 203 by a third pin 204.

[0044] The side of the placement plate 205 and the inner surface of the groove 203 are respectively fixedly connected to a first fixing rod 206 and a second fixing rod 207. The surface of the first fixing rod 206 and the second fixing rod 207 is movably connected to an annular frame 208. The side of the second fixing plate 200 is provided with a fourth through hole 209.

[0045] The arrangement of the first fixing rod 206, the second fixing rod 207, and the annular frame 208 facilitates the unfolding of the placement plate 205. After the placement plate 205 is rotated, the first fixing rod 206 and the second fixing rod 207 are located at both ends inside the annular frame 208, making the placement plate 205 parallel to the third fixing plate 300. Workers can place tools that are not frequently used on the surface of the placement plate 205.

[0046] See Figure 1 , Figure 2 , Figure 3 and Figure 9 The support plate 3 includes a third fixing plate 300. There are two third fixing plates 300, and each of the two third fixing plates 300 has a cavity 301 on its opposite surface. A sliding sleeve 302 is fixedly connected in the cavity 301. A sliding rod 303 is slidably connected in the sliding sleeve 302. A fixing block 304 is fixedly connected to one end of the sliding rod 303. The opposite ends of the two sliding rods 303 are fixedly connected by a connecting plate 306.

[0047] The expanded area of ​​the two third fixing plates 300 and the connecting plate 306 allows for the placement of more tools and equipment, thus improving the practicality of using the third fixing plates 300.

[0048] See Figure 4The first support rod 4 has the same structure as the second support rod 5 and the third support rod 6. The first support rod 4 includes a threaded cylinder 400. The threaded cylinder 400 is internally threaded with a threaded post 401. The bottom end of the threaded post 401 is fixedly connected to a third fixing rod 402. The surface of the third fixing rod 402 is provided with a rubber sleeve 403.

[0049] When the third fixing rod 402 is rotated by twisting the rubber sleeve 403, the threaded column 401 can be rotated, thereby changing the position of the support pad 7, making it easier for the support pad 7 to contact the ground to support the third fixing plate 300. At the same time, the placement effect of the support rod can be improved when the support pad 7 contacts the through hole.

[0050] Specifically, a connecting block 105 is fixedly connected to the side of the first fixing plate 100. The connecting block 105 is U-shaped and is fixedly connected to the third fixing plate 300 by a pin. The setting of the connecting block 105 and the pin facilitates the change of the position and angle of the third fixing plate 300, so that the whole can be folded and unfolded, which improves the support effect for the measuring tool.

[0051] Specifically, the second fixing plate 200 has a sliding groove 210 that connects to the fourth through hole 209 on its side. The second fixing plate 200 and the groove 203 have a placement groove 211 on the same side. When the support plate 3 is folded, the slider 307 can be accommodated through the placement groove 211, which makes it easy for the locking rod 308 to engage with the first fixing sleeve 213.

[0052] Specifically, the second fixing plate 200 has a fifth through hole 212 on its side, and a first fixing sleeve 213 is fixedly connected in the fifth through hole 212. The upper surface of the second fixing plate 200 has a slot 214.

[0053] Specifically, a second fixing sleeve 305 is fixedly connected to the surface of the fixing block 304. The second fixing sleeve 305 is slidably connected in the cavity 301. The second fixing sleeve 305 is made of elastic material and has a certain friction when sliding in the cavity 301, which can prevent the two third fixing plates 300 from changing their positions on their own.

[0054] Specifically, sliders 307 are fixedly connected to the surfaces of both third fixing plates 300. The sliders 307 are slidably connected in the grooves 210. Both sliders 307 and grooves 210 are set in an inverted T shape. After the sliders 307 are connected to the grooves 210, the stability between the third fixing plate 300 and the second fixing plate can be guaranteed, and the support effect of the third fixing plate 300 is improved.

[0055] Specifically, a locking rod 308 is fixedly connected to the lower surface of the third fixing plate 300. The locking rod 308 is engaged in the first fixing sleeve 213, which is made of elastic material, specifically rubber. After the locking rod 308 is engaged with the first fixing sleeve 213, the first bracket 1 and the support plate 3 can be fixed relative to each other.

[0056] Specifically, a stop block 106 is fixedly connected to the side of the first fixing plate 100. The stop block 106 engages with the slot 214. The slot 214 facilitates the placement of the stop block 106, and the stop block 106 can prevent the angle between the support plate 3 and the first bracket 1 from increasing when the support plate 3 and the first bracket 1 are at a 90-degree angle.

[0057] Specifically, the bottom ends of the first fixing plate 100, the second fixing plate 200, and the third fixing rod 402 are all fixedly connected to the side of the placement plate 205 with support pads 7. The support pads 7 are made of elastic material. The setting of the elastic support pads 7 can ensure the friction of the first fixing plate 100, the second fixing plate 200, the third fixing rod 402, and the placement plate 205, so as to facilitate fixing the support rod to the through hole or the ground.

[0058] The working principle of this invention is as follows:

[0059] like Figure 1 As shown, the device is foldable for easy carrying by staff when needed.

[0060] like Figure 2 As shown, when using the device, the third fixing plate 300 is rotated and the second fixing plate 200 is moved so that the slider 307 engages with the slide groove 210. During the adjustment of the third fixing plate 300, the position of the support rod can be changed through the ball joint 102 and the pin. Then, the position of the threaded column 401 in the threaded cylinder 400 can be adjusted by turning the rubber sleeve 403. Then, when the corresponding support pad 7 contacts the ground, the first fixing plate 100 and the second fixing plate 200 can be fixed, and the third fixing plate 300 can be fixed. At the same time, during the use of the support plate 3, the third fixing plate 300 can be pulled to change the distance between the two third fixing plates 300, so that the connecting plate 306 in the cavity 301 is exposed, which makes it convenient to use the support plate 3.
