Description

Technical Field

[0001] This utility model relates to the field of engineering construction equipment, and in particular to a gap measuring device for use in confined spaces. Background Technology

[0002] With the continuous development of science and technology, new techniques for bridge construction without scaffolding are constantly emerging, and bridge rotation is one of them. Based on the direction of rotation of the bridge structure, it can be divided into vertical rotation construction method, horizontal rotation construction method (referred to as vertical rotation and horizontal rotation, with horizontal rotation further divided into pier top rotation and pier bottom rotation), and a combination of horizontal and vertical rotation methods, with horizontal rotation being the most widely used. Bridge rotation construction is suitable for special river channels spanning deep valleys and rapid currents where hoisting is difficult, offering advantages such as reduced hoisting costs, safety, reliability, and good overall integrity. Recently, an increasing number of bridges crossing railways and highways have begun to use the rotation construction method, which does not affect normal railway or highway transportation and offers significant savings in scaffolding materials, safety, reliability, and reduced construction difficulty.

[0003] In related technologies, the gap between the slide and the support foot is generally checked by measuring personnel entering the reserved post-sealing concrete space and using a feeler gauge. This method requires the measuring personnel to move within the reserved post-sealing concrete space. The space is small and there are interferences from supports, embedded parts, etc., which makes the operation inconvenient, the measurement efficiency low, the measuring personnel stay in the narrow space for a long time, and the operation risk is high.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model provides a gap measuring device for confined spaces, which can solve the problems of inconvenient operation, low measurement efficiency, long time for measuring personnel to stay in confined spaces, and high operational risks in related technologies.

[0027] See Figure 1 As shown, this utility model provides a gap measuring device for confined spaces, which may include: a handheld rod assembly 3; and a measuring component 1, which may include: a ruler 4, which is installed at one end of the handheld rod assembly 3 and whose width gradually decreases in the direction away from the handheld rod assembly 3; a scale 5, which is set along the extension direction of the ruler 4; and a vernier 6, which is installed on the ruler 4 and can move along the scale 5 on the ruler 4. In this embodiment, the measuring component 1 is moved to the gap to be measured by holding the handheld rod assembly 3, and the ruler 4 is inserted into the gap in the horizontal direction. Since the width of the ruler 4 increases along the insertion direction, the vernier 6 is driven to move on the ruler 4 while the ruler 4 is inserted into the gap. Finally, after the measuring component 1 is removed, the data of the vernier 6 at the scale 5 on the ruler is read, which is the gap data. This solves the problems in related technologies, such as inconvenience for measuring personnel to enter complex construction environments, inconvenient operation, low measurement efficiency, long time for measuring personnel to stay in confined spaces, and high operational risks.

[0028] See Figure 2 and Figure 3 As shown, in some embodiments, the ruler body 4 is a right-angled triangle with a slope 41 on one side. The scale 5 is set on the slope 41, and the vernier 6 is movably mounted on the slope 41. In this embodiment, by setting a slope 41 on one side of the ruler body 4, the vernier 6 will be driven to move on the slope 41 when the ruler body 4 is inserted into the gap. After it moves out, the data of the vernier 6 at the scale 5 is the gap data, which can meet the gap measurement needs in small spaces.

[0029] See Figure 4 As shown, in some embodiments, a connecting component 2 is installed on the handheld rod assembly 3, and the ruler body 4 is detachably installed on the connecting component 2. In this embodiment, by connecting the ruler body 4 to the handheld rod assembly 3 through the connecting component 2, the ruler body 4 can be disassembled as needed and replaced with a ruler body 4 of the corresponding specification, thereby making the measuring device suitable for more environments.

[0030] See Figure 4 As shown, in some embodiments, the connecting component 2 includes a U-shaped part 7, and the ruler body 4 is installed in the U-shaped groove of the U-shaped part 7. In this embodiment, by fixing the connecting component 2 in the U-shaped groove of the U-shaped part 7, the connecting component 2 can be kept in a fixed position, preventing the connecting component 2 from moving and facilitating measurement.

[0031] See Figure 2 As shown, in some embodiments, the U-shaped component 7 is equipped with a quick-release screw assembly 8, and the ruler body 4 is provided with a mounting hole. The quick-release screw assembly 8 passes through the mounting hole to fix the ruler body 4. In this embodiment, the ruler body 4 is fixed to the U-shaped component 7 by the quick-release screw assembly 8, which can facilitate the installation and removal of the ruler body 4. The ruler body 4 of appropriate specifications can be replaced as needed, and the application range is wider.

[0032] See Figure 4 As shown, in some embodiments, the bottom of the U-shaped part 7 is fixed with a straight threaded rod 9, and the handheld rod assembly 3 is provided with a matching internal thread. The two are connected by threads. In this embodiment, by connecting the U-shaped part 7 and the handheld rod assembly 3 by threads, it is convenient to install and disassemble the U-shaped part 7. The U-shaped part 7 of appropriate specifications can be replaced as needed, and the application range is wider.

[0033] See Figure 5 As shown, in some embodiments, the handheld lever assembly 3 may include an inner circular rod 10 and an outer circular rod 12, with the outer circular rod 12 sleeved around the outside of the inner circular rod 10. In this embodiment, by setting the inner circular rod 10 and the outer circular rod 12, the length of the handheld lever assembly 3 is adjustable, making it more flexible in use.

[0034] See Figure 2 As shown, in some embodiments, a press-locking assembly 11 is installed on the outer circular rod 12. The press-locking assembly 11 is used to lock the inner circular rod 10. In this embodiment, the press-locking assembly 11 can be locked after the hand handle assembly 3 is adjusted to the required length, which is more convenient to use.

[0035] See Figure 2 As shown, in some embodiments, the handheld rod assembly 3 is wrapped with an anti-slip strap 13. In this embodiment, the anti-slip strap 13 is provided at the end of the handheld rod assembly 3 for hand gripping, which can prevent the handheld rod assembly 3 from slipping out of the hand during use.

[0036] During installation, install the measuring component 1 into the connecting component 2. Align the connecting component 2 with the top thread of the inner round rod 10 and screw it in until locked. If necessary, pull out the inner round rod 10 to adjust the working length of the telescopic handheld rod assembly 3 to meet the measurement needs of different depth spaces.

[0037] During measurement, first adjust the working length of the telescopic handheld rod assembly 3 and the angle between the measuring component 1 and the connecting component 2 according to the relationship between the measurement gap position and the measuring personnel, and lock them with the quick-release screw assembly 8; return the vernier 6 to the zero position, move the measuring component 1 to the gap to be measured through the handheld rod assembly 3, insert it into the gap in the horizontal direction, then move the measuring component 1 out through the handheld rod and read the data of the vernier 6 at the scale 5. To prevent errors in a single measurement, measurements can be taken at multiple angles and positions; after the measurement is completed, the inner round rod 10 is retracted into the outer round rod 12 by pressing the locking assembly 11 for easy storage.

[0038] The principle of the gap measuring device for confined spaces provided in this embodiment of the utility model is as follows:

[0039] Measuring component 1 is located at the top of the device and can measure and collect the required gap data. Connecting component 2 is used to connect measuring component 1 and telescopic handheld rod component 3. The telescopic handheld rod component 3 can be adjusted in working length by pressing locking component 11 as needed, for measurement needs in small spaces. This measuring device is flexible in structure, easy to carry, and convenient to operate. It is suitable for gap measurement in small spaces. The device is easy to assemble and can extend and adjust the length of the handheld rod and the angle of the measuring component according to actual conditions. It solves the problems in related technologies, such as inconvenience for measuring personnel to enter complex construction environments, interference from supports and embedded parts, inconvenient operation, low measurement efficiency, long time for measuring personnel to stay in confined spaces, and high operational risks.
