Description

Technical Field

[0001] The utility model belongs to the technical field of evacuation platform measurement, and in particular relates to a diagonal brace measurement tool for an evacuation platform. Background Art

[0002] As a special facility for emergency evacuation in subway tunnels, the evacuation platform is composed of platform panels, steel beams, diagonal braces and other components. Before installation, due to the limit requirements in the tunnel, the width of the panel and the length of the steel beam change with the limit. At this time, it is necessary to measure the length and angle of the platform diagonal brace, and then process and produce according to the data.

[0003] At present, the measurement of the diagonal braces of the evacuation platform in the subway tunnel is roughly calculated based on the trigonometric function relationship between the length of the steel beam and the curvature of the tunnel. Therefore, when ordering materials, the length calculation error needs to be fully considered. Different lengths of diagonal braces need to be ordered in larger quantities, and then the angle error is eliminated by gaskets. This will inevitably lead to material waste and low construction efficiency, and some diagonal braces cannot meet on-site needs. Utility Model Content

[0021] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0022] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0023] Example 1

[0024] This embodiment provides a diagonal brace measuring tool for an evacuation platform, comprising a level ruler 1 , an arc ruler 2 , a telescopic mechanism 3 , and an arc positioning plate 4 .

[0025] like Figure 1 As shown, a scale is provided on the side wall of the level ruler 1, which can measure the length of the steel beam in real time. The right end of the level ruler 1 is fixedly connected to the top of the arc-shaped positioning plate 4. A slide groove 5 is provided at the bottom end of the level ruler 1 along its length direction. A slider 6 is slidably fitted in the slide groove 5. The slider 6 is fixedly connected to the arc ruler 2 so that the arc ruler 2 can slide back and forth along the length direction of the level ruler 1.

[0026] One end of the telescopic mechanism 3 is hinged to the arc ruler 2, and the other end of the telescopic mechanism 3 is hinged to the bottom end of the arc positioning plate 4, so that when the arc ruler 2 slides back and forth along the length direction of the horizontal ruler 1, the telescopic mechanism 3 can be driven to swing back and forth, and the length of the telescopic mechanism 3 changes during the swinging process. A scale is provided on the telescopic mechanism 3, and after the length of the telescopic mechanism 3 changes, the length of the telescopic mechanism 3 can be obtained in real time through the scale.

[0027] Among them, one end of the telescopic mechanism 3 is hinged to the arc ruler 2 through a hinged rod, and the axis of the hinged rod is located at the center of the arc ruler 2, so that the arc ruler 2 can measure the real-time angle of the telescopic mechanism 3.

[0028] The arc-shaped positioning plate 4 is used to fit with the inner wall of the tunnel. Since the curvature of the tunnel surface is determined, the arc-shaped positioning plate 4 can be processed according to the curvature data of the tunnel surface to ensure that the arc-shaped positioning plate 4 can fit closely with the tunnel surface.

[0029] Based on the above structure, when using the measuring tool, the arc positioning plate 4 is placed on the tunnel, the length of the steel beam at the current position is measured by the horizontal ruler 1, and then the slider 6 is slid to the specified position, so that the arc ruler 2 is fixed at the corresponding scale position (steel beam length) of the horizontal ruler 1. At this time, the telescopic mechanism 3 overlaps with the diagonal brace, and the length of the telescopic mechanism 3 is the length of the diagonal brace. The length of the diagonal brace can be read through the scale on the telescopic mechanism 3, and the angle of the diagonal brace can be read from the arc ruler 2, and the data is recorded. Repeat this operation to measure and record other diagonal braces in turn, and the measurement of the diagonal brace of the evacuation platform in the tunnel can be quickly completed.

[0030] To sum up, the evacuation platform brace measurement tool provided in this embodiment adopts a handheld design. The arc positioning plate 4 is placed against the arc surface of the tunnel. By setting the length of the steel beam and then observing the scale data on the surface of the measuring ruler, the brace angle and the brace length can be quickly obtained, ensuring that the brace data of each platform is accurate, avoiding calculation errors, realizing accurate ordering and production of braces, eliminating material waste, and requiring no adjustment during on-site installation, thereby improving construction efficiency.

[0031] In this embodiment, the telescopic mechanism 3 may include an outer cylinder 301 and an inner cylinder 302. Figure 2 As shown, the inner cylinder 302 is slidably sleeved in the outer cylinder 301, and a scale is provided on the outer wall of the inner cylinder 302. When the inner cylinder 302 slides to different positions inside the outer cylinder 301, the bottom end of the outer cylinder 301 indicates different positions on the scale of the inner cylinder 302. Therefore, the length data of the inner cylinder 302 at different positions inside the outer cylinder 301 can be measured in advance, and then the length data can be recorded on the outer wall of the inner cylinder 302.

[0032] Symmetrical scales are provided on the outer walls of both sides of the inner cylinder 302. In this way, the staff can obtain the length data of the telescopic mechanism 3 from both sides without changing the direction.

[0033] Scales are provided on the outer walls of both sides of the level ruler 1. Similarly, the staff can obtain the length data of the steel beam from both sides without the staff changing the direction.

[0034] like Figure 3 As shown, in this embodiment, the cross section of the slide groove 5 is a T-shaped structure, and the cross section of the slider 6 is also a T-shaped structure.

[0035] In order to fix the slider 6 at any time, a plurality of screw holes are evenly spaced along the length direction of the level ruler 1 on the top surface, the screw holes are connected to the slide grooves 5, and a locking rod 8 is screwed into the screw holes, and the bottom end of the locking rod 8 abuts against the slider 6.

[0036] By rotating the locking rod 8 so that the bottom end of the locking rod 8 abuts against the slider 6 , the slider 6 can be fixed to prevent the slider 6 from sliding and causing errors in the measurement data.

[0037] A rotating disk is fixed on the top of the locking rod 8. The setting of the rotating disk facilitates the staff to quickly rotate the locking rod 8.

[0038] In this embodiment, a pointer 7 is installed on the telescopic mechanism 3 by means of screws. The pointer 7 points to the center of the arc ruler 2 and is close to the arc ruler 2. The pointer 7 allows the staff to quickly read the angle data of the telescopic mechanism 3.

[0039] Example 2

[0040] like Figure 2-3 As shown, in this embodiment, the arc ruler 2 includes a connecting plate 201, and fan-shaped plates 202 fixedly arranged on both sides of the bottom end of the connecting plate 201, and an angle ruler for measuring angle data is provided on the outer wall of the fan-shaped plate 202. The connecting plate 201 is fixedly connected to the bottom end of the slider 6, and a connecting rod 203 is fixed to the top end of the outer cylinder 301. A rotating seat 204 is fixed to the bottom end of the connecting plate 201, and the connecting rod 203 is hinged to the rotating seat 204.

[0041] In this way, the staff can obtain the angle data of the telescopic mechanism 3 from both sides, and the telescopic mechanism 3 will not block the arc ruler 2.

[0042] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
