Description

A testing device for precast composite slabs Technical Field

[0001] This utility model relates to the field of precast slab testing technology, and in particular to a precast composite slab testing device. Background Technology

[0002] Precast composite slabs are a type of precast concrete component widely used in construction engineering, and their surfaces are typically quite flat. However, during the production and construction of precast composite slabs, precise measurement of their length and width is crucial to ensure they meet design requirements and relevant standards. Currently, measuring tapes are commonly used to measure the length and width of precast composite slabs, but this method has significant drawbacks when measuring large slabs or batches. Traditional two-person measurement methods require repeated positioning and stretching operations, resulting in lengthy measurements. When measuring large composite slabs, personnel must frequently move and repeatedly stretch the tape measure. With multiple composite slabs, this high-intensity, repetitive operation easily leads to operator fatigue and decreased measurement efficiency. This not only fails to meet the requirements of accuracy and timeliness in engineering projects but also fails to meet the high-efficiency and precise demands of modern engineering construction. Summary of the Invention

[0003] The purpose of this invention is to address the problems of existing technologies that use measuring tapes to measure the length and width of precast composite slabs, which are cumbersome, time-consuming, and prone to causing personnel fatigue when measuring large or batch sizes, resulting in low measurement efficiency and difficulty in meeting engineering requirements. This invention proposes a precast composite slab testing device.

[0004] The technical solution of this utility model is as follows: A precast composite slab testing device, comprising a support and a concave remote control vehicle, further comprising: a protective cover fixedly connected to the end of the concave remote control vehicle away from the support, wherein a measuring tape is provided inside the protective cover, and a measuring tape with a movable through-type measuring strip is provided inside the measuring tape and passing through the concave remote control vehicle and the support; a mounting groove opened at the end of the support away from the concave remote control vehicle, wherein a starting point clamping plate is fixedly connected inside the mounting groove, and the starting point clamping plate is fixedly connected to the end of the measuring tape away from the measuring tape; and an observation mechanism, set inside the concave remote control vehicle, for recording the measurement structure of the measuring tape.

[0005] Optionally, the observation mechanism includes an observation port located inside a concave remote-controlled vehicle. The observation port is equipped with multiple linearly arranged lighting lamps, and the concave remote-controlled vehicle is also equipped with an observation plate corresponding to the observation port.

[0006] Optionally, the support is provided with a protrusion, and the end of the concave remote control vehicle near the support is provided with a groove for the protrusion to be inserted into. The end of the support near the concave remote control vehicle is provided with a pair of positioning suction grooves, and the end of the concave remote control vehicle near the support is fixedly connected with a positioning plug inserted into the positioning suction groove.

[0007] Optionally, each of the positioning plugs has a tapered plug at the end away from the concave remote control car, and the positioning suction groove has a magnetic sleeve inside to hold the tapered plug.

[0008] Optionally, a handle is fixedly connected to the upper surface of the support.

[0009] Optionally, the end of the support away from the concave remote control vehicle is fixedly connected to a clamping plate that holds the prefabricated composite plate.

[0010] Optionally, the bottom of the concave remote control vehicle is provided with multiple pairs of rubber wheels that are closely attached to the prefabricated composite plate.

[0011] Optionally, the protective cover has multiple fixing blocks fixedly connected inside, and the end of each fixing block away from the inner wall of the protective cover is fixedly connected to a measuring tape.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes the cooperation of a support, a concave remote-controlled vehicle, a measuring tape, and an observation mechanism to automatically release the measuring tape from the tape via the concave remote-controlled vehicle. This ensures automatic measurement of the precast composite slab, avoiding repeated manual stretching and reducing operation time. It also reduces labor intensity, as measuring personnel do not need to frequently move and stretch the measuring tape, thus reducing fatigue. Furthermore, it improves measurement accuracy, avoiding inaccuracies caused by human fatigue, ensuring data accuracy and timeliness, and meeting the needs of modern engineering construction.

[0024] Example

[0025] As shown in Figures 1 to 3, the present invention proposes a precast composite slab testing device, comprising a support 1 and a concave remote control vehicle 2. The concave remote control vehicle 2 is a type of remote control vehicle designed to travel stably along a straight line. The bottom of the concave remote control vehicle 2 is provided with multiple pairs of rubber wheels 21 that are in close contact with the precast composite slab. The rubber wheels 21 increase the friction between the concave remote control vehicle 2 and the precast composite slab, preventing slippage and ensuring the tape 33 inside the measuring tape 31 can be pulled out. A handle 13 is fixedly connected to the upper surface of the support 1. A protective cover 3 is fixedly connected to the end of the concave remote control vehicle 2 away from the support 1. Several fixing blocks 32 are fixedly connected inside the protective cover 3. The ends of the fixing blocks 32 away from the inner wall of the protective cover 3 are all fixedly connected to the measuring tape 31. The measuring tape 31 is located inside the protective cover 3. The measuring tape is a tool used for measuring length and typically consists of a tape 33, a casing, a pull ring, and a braking device. The measuring tape 31 has a tape 33 that moves through the concave remote control car 2 and the support 1. The tape 33 is the part of the measuring tape 31 used to measure length. A mounting groove 11 is opened at the end of the support 1 away from the concave remote control car 2. A starting point plate 34 is fixedly connected inside the mounting groove 11. The starting point plate 34 is fixedly connected to the end of the tape 33 away from the measuring tape 31.

[0026] As shown in Figures 2 and 3, the concave remote-controlled vehicle 2 has an observation mechanism inside for recording the measurement structure of the measuring tape 33. This mechanism includes an observation port 35 located within the concave remote-controlled vehicle 2. Inside the observation port 35 are several linearly arranged lighting lamps 36, which are always on during operation of the concave remote-controlled vehicle 2 to ensure that the inspector can clearly observe the conditions inside the observation port 35. The concave remote-controlled vehicle 2 also has an observation plate 24 corresponding to the observation port 35. The observation plate 24 is made of tempered glass to ensure that the scale on the measuring tape 33 is aligned with the length of the prefabricated composite plate edge when observed from top to bottom.

[0027] Additionally, as shown in Figure 2, the support 1 has a protrusion 101, and the concave remote control car 2 has a groove 23 at one end near the support 1 for the protrusion 101 to be inserted into. The support 1 also has a pair of positioning suction slots 102 at one end near the concave remote control car 2. A positioning insert 22 is fixedly connected to the end of the concave remote control car 2 near the support 1, which is inserted into the positioning suction slot 102. After the positioning insert 22 is inserted into the positioning suction slot 102, the concave remote control car 2 can only be moved away from the support 1 by pulling force. The support 1 has a remote control for controlling the switch and speed of the concave remote control car 2.

[0028] It is worth noting that, as shown in Figure 2, the end of the positioning plug 22 away from the concave remote control car 2 is equipped with a conical plug. The conical plug is made of a metal material that is attracted by a magnetic sleeve. The positioning suction groove 102 has a magnetic sleeve inside that attracts the conical plug. The magnetic sleeve is usually made of neodymium iron boron magnet, which is a rare earth permanent magnet material with strong magnetism.

[0029] Furthermore, as shown in Figures 1 to 3, a clamping plate 12 that holds the prefabricated composite slab is fixedly connected to the end of the support 1 away from the concave remote control vehicle 2. The starting point clamping plate 34 is fixed in the mounting groove 11, and its function is to ensure that the end of the clamping plate 12 that holds the prefabricated composite slab is the starting point.

[0030] In this embodiment, when using the precast composite slab inspection device, as shown in Figure 1, the support 1 is first placed on one end of the precast composite slab, and the clamping plate 12 at the end of the support 1 is tightly clamped to the end of the precast composite slab. Then, the concave remote control vehicle 2 can be started. The concave remote control vehicle 2 moves on the upper surface of the precast composite slab through multiple pairs of rubber wheels 21 at the bottom. Then, as shown in Figure 2, the concave remote control vehicle 2 drives the protective cover 3 and the measuring tape 31 inside it to move, so that the measuring tape 33 is stretched out from the measuring tape 31. Until the observation plate 24 on the concave remote control vehicle 2 slowly moves to the other end of the precast composite slab, at this time the protective cover 3 is detached from the other end of the precast composite slab and suspended in the air, while the observation plate 24 is located directly above the other end of the precast composite slab. The concave remote control vehicle 2, through the principle of the center of gravity being biased towards the support 1, ensures that the concave remote control vehicle 2 will not fall off the other end of the precast composite slab. Finally, the starting position of the measuring tape 33 can be determined through the starting plate 34, and the length of the measuring tape 33 aligned with the other end of the precast composite slab can be seen through the observation plate 24. By repeating the above operation, the size of the precast composite slab can be quickly determined.

[0031] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
