DETAILED DESCRIPTION

[0047] In order to make the purpose, characteristics and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] Reference Figure 1 - Figure 4The bridge deflection detection device provided by the embodiment of the application comprises a support frame 100 and a detector main body 200 arranged on the support frame 100, two protective members 300 are arranged on the detector main body 200, one of the two protective members 300 is arranged on the side of the detector main body 200 where the ocular lens is located, and the other is arranged on the side of the detector main body 200 where the objective lens is located, the display screen of the detector main body 200 is located on the side of the ocular lens, and the ocular lens or the objective lens can be protected at the moment when the deflection detection device falls to the ground by using the two protective members 300. Specifically, taking the protective member 300 on the side of the ocular lens as an example, the protective member 300 comprises two support plates 310, the two support plates 310 are fixedly connected to the two sides of the detector main body 200 respectively, a vertical sliding groove 320 is formed in the front side of the support plate 310, a plurality of sliding blocks 330 are slidably connected in the sliding groove 320, and a first connecting rope 340 is fixedly connected between the two sliding blocks 330 connected in the same sliding groove 320; a plurality of anti-collision rods 350 are arranged on the two support plates 310, and the two ends of the anti-collision rod 350 are rotatably connected with the two sliding blocks 330 corresponding to the horizontal positions on the two support plates 310; a control member 360 is installed on the support plate 310, and the control member 360 is used to control the dispersion or gathering of the sliding blocks 330. The installation of the protective member 300 on the side of the objective lens is the same as that on the side of the ocular lens, and will not be described here.

[0049] Further introduction will be made in combination with specific use scenarios. When the operator uses the deflection detection device to detect, all the anti-collision rods 350 need to be concentrated on the top to avoid the operator from being hindered when observing through the ocular lens or reading the display screen; when detecting or moving the detection device, once the detection device falls, the anti-collision rods 350 are dispersed quickly by using the control member 360 to shield the ocular lens or the objective lens, so that the ocular lens or the objective lens will not touch the ground, thereby protecting the ocular lens and the objective lens, and effectively avoiding the damage of the objective lens, the ocular lens and the display screen, and improving the use safety and service life of the detection device.

[0050] With reference to Figure 2 and Figure 3 The protective member 300 further comprises an anti-collision leaf 370, the anti-collision leaf 370 is fixedly connected to the outer periphery of the anti-collision rod 350, the anti-collision leaves 370 on the adjacent two anti-collision rods 350 are fixedly connected by a second connecting rope 380, and the width of the anti-collision leaf 370 is equal to the length of the first connecting rope 340.

[0051] In combination with a specific use scene, the anti-collision leaves 370 are fixedly connected on the outer periphery of the anti-collision rods 350, and the second connecting ropes 380 are fixedly connected between the anti-collision leaves 370 on the adjacent two anti-collision rods 350, and the width of the anti-collision leaves 370 is equal to the length of the first connecting ropes 340, so that when the anti-collision rods 350 are fully unfolded, the anti-collision leaves 370 are further unfolded to fill the gap between the adjacent two anti-collision rods 350, thereby further ensuring the comprehensiveness of the shielding of the objective lens or the ocular lens, and the objective lens and the ocular lens can be more effectively protected from collision, and the protection effect of the ocular lens and the objective lens is improved.

[0052] With reference to Figure 4 A spring groove 311 is formed in the support plate 310, and the control member 360 comprises a connecting block 362 slidingly arranged in the spring groove 311. A pushing block 361 is fixedly connected to the side of the lowermost sliding block 330. Here, the lowermost sliding block 330 refers to the lowermost sliding block 330 among all the sliding blocks 330 on the same support plate 310. One end of a first pulling rope 363 is fixedly connected to the connecting block 362, and the other end of the first pulling rope 363 is fixedly connected to the bottom of the lowermost sliding block 330. A tension spring 364 is arranged in the spring groove 311, one end of the tension spring 364 is fixedly connected to the connecting block 362, and the other end of the tension spring 364 is fixedly connected to the spring groove 311. An opening and closing mechanism 365 is further arranged on the support plate 310, and the opening and closing mechanism 365 can be used to lock the position of the pushing block 361 when the pushing block 361 moves to the opening and closing mechanism 365. Specifically, the opening and closing mechanism 365 comprises a sliding rail 3651 fixedly arranged horizontally on the side of the support plate 310, a lock plate 3652 slidingly connected to the sliding rail 3651, a connecting plate 3653 fixedly arranged on the support plate 310, a compression spring 3654, one end of which is fixedly connected to the lock plate 3652, and the other end of which is fixedly connected to the connecting plate 3653. A locking groove 3655 is formed in the lock plate 3652, and a locking pin 3656 is fixedly arranged on the side of the pushing block 361 close to the lock plate 3652. When the locking pin 3656 is inserted into the locking groove 3655, the position of the pushing block 361 is locked. The locking pin 3656 is fixedly arranged on the side of the pushing block 361 close to the lock plate 3652, and when the locking pin 3656 is inserted into the locking groove 3655, the position of the pushing block 361 is locked. A trigger rod 3657 is fixedly arranged on the lock plate 3652, and the axis of the trigger rod 3657 is parallel to the axis direction of the objective lens.

[0053] Further, with reference to Figure 2 And Figure 3 A guide inclined surface 36521 is formed in the bottom of the lock plate 3652, which is used to facilitate the insertion of the locking pin 3656 into the locking groove 3655. Specifically, the guide inclined surface 36521 is formed by inclining upward from the side of the bottom of the lock plate 3652 away from the locking pin 3656.

[0054] Further, with reference to Figure 2 , Figure 3 or Figure 4 , the control 360 further comprises a connecting rod 3658, which is fixedly connected with the two lock plates 3652 at both ends.

[0055] Further, the specific use scenarios are introduced as follows. Before the operator measures, the push blocks 361 of the eyepiece and the objective lens are pushed respectively. Taking the protective piece 300 on the side of the eyepiece as an example, when the push block 361 is moved upward, the lowermost slider 330 will be moved upward together with the anti-collision rod 350 and the anti-collision leaf 370, and then all the sliders 330, the anti-collision rod 350 and the anti-collision leaf 370 will be moved upward in turn until the locking pin 3656 abuts against the guide slope 36521 of the lock plate 3652. During this process, the anti-collision leaf 370 will be folded in turn under the action of the second connecting rope 380, and then the lock plate 3652 will be moved toward the compression spring 3654 as the push block 361 continues to move upward, so that the locking pin 3656 passes the guide slope 36521 and moves to the coaxial line of the locking groove 3655. Under the action of the compression spring 3654, the lock plate 3652 moves toward the push block 361, so that the locking pin 3656 is inserted into the locking groove 3655. Thus, the anti-collision rod 350 and the anti-collision leaf 370 are concentrated above the eyepiece, which does not affect the observation of the eyepiece by the operator and does not affect the reading by the operator through the display screen. At this time, the tension spring 364 is in the maximum stretched state. When the detection device is accidentally tilted, if the direction of the tilt is the direction in which the eyepiece touches the ground, the trigger rod 3657 will first touch the ground, and then the lock plate 3652 will be moved toward the compression spring 3654, so that the locking pin 3656 is separated from the locking groove 3655, and the sliders 330 are moved downward in turn under the action of the tension spring 364 and the first connecting rope 340, and the anti-collision rod 350 is moved downward together with the sliders 330. At the same time, the anti-collision leaf 370 will be unfolded under the action of the second connecting rope 380, so that the eyepiece and the display screen are completely covered by the anti-collision leaf 370 and the anti-collision rod 350. Thus, the objective lens and the display screen can be protected from being damaged. Similarly, when the detection device is tilted in the direction in which the objective lens touches the ground, the protective piece 300 on the side of the objective lens will also protect the objective lens. The function of the connecting rod 3658 is that when the objective lens or the eyepiece is not directly tilted to the ground, even if only one trigger rod 3657 touches the ground, the connecting rod 3658 will also move the two lock plates 3652 away from the locking pin 3656, so as to ensure the stability and smoothness of the separation of the locking pin 3656 and the locking groove 3655, and improve the stability of the protection of the objective lens or the eyepiece.

[0056] With reference to Figure 2 , Figure 3 andFigure 4 As a specific embodiment of the present application, the auxiliary part 400 is further included, which comprises a double-shaft motor 410 installed on the detector main body 200, two winches 420 are installed at each shaft end of the double-shaft motor 410, a ratchet mechanism 430 is installed between each winch 420 and the output shaft of the double-shaft motor 410, a second pull rope 440 is fixedly connected to each winch 420, and the other end of each second pull rope 440 is correspondingly fixedly connected to the top of a sliding block 330 provided with a push block 361.

[0057] In combination with a specific use scenario, the auxiliary part 400 is mainly used to more conveniently open the protective parts 300 of the objective lens and the ocular lens. Specifically, the double-shaft motor 410 is started, and then the winches 420 are driven to rotate by the ratchet mechanism 430, so as to pull the second pull rope 440, and the sliding block 330 connected with the push block 361 is synchronously lifted, and then all the sliding blocks 330 are sequentially lifted, and further all the anti-collision rods 350 and the anti-collision leaves 370 are lifted until the locking pin 3656 is inserted into the locking groove 3655; in this way, the opening of the anti-collision rods 350 and the anti-collision leaves 370 is more convenient.

[0058] When the detection device is tilted and the trigger rod 3657 touches the ground, the locking plate 3652 moves away from the locking pin 3656, and at the moment when the locking pin 3656 is separated from the locking groove 3655, the sliding block 330 is immediately pulled down under the action of the tension spring 364, and then the anti-collision rods 350 and the anti-collision leaves 370 are dispersed to protect the objective lens or the ocular lens. It is explained here that the reason why the ratchet mechanism 430 is used in the present application is to ensure that all the winches 420 are synchronously moved after the double-shaft motor 410 is rotated by using the transmission of the ratchet mechanism 430; however, when one of the ocular lens and the objective lens is placed on the ground, the corresponding trigger rod 3657 touches the ground to separate the corresponding locking pin 3656 and the locking groove 3655, and the other protective part 300 is not affected, so that the state of the two protective parts 300 does not interfere with each other, and the stability of protecting the objective lens and the ocular lens is ensured.

[0059] It should be understood that the various forms of flow shown above can be used to reorder, add or delete steps. For example, the steps described in the present application can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions of the present application can be achieved, which are not limited herein.
