Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering detection, and relates to a spring type T-beam camber full-process measuring device for measuring the camber of a prestressed concrete T-beam. Background Art

[0002] T-beam camber refers to the amount of upward deformation of a prestressed concrete T-beam during long-term storage or use, caused by various factors (such as concrete creep and shrinkage). Camber is an important indicator for measuring the degree of upward camber of a T-beam during use and is crucial for ensuring bridge stability and safety.

[0003] Current methods for measuring the camber of prestressed concrete T-beams primarily include the traditional level, laser rangefinder, total station, digital level, and inclination sensor methods. These methods, such as the traditional level, rely on manual measurement, resulting in limited accuracy and a lengthy measurement process. The total station method, for example, requires specialized equipment and operators, resulting in a complex measurement process and susceptible to environmental and temperature fluctuations. Furthermore, methods such as the laser rangefinder, digital level, and inclination sensor require sophisticated instruments and are relatively costly. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides a spring-type T-beam camber full-process measurement device. By setting up a slide rail on the upper part of the prestressed concrete T-beam and then moving the spring-type measuring head to measure the T-beam camber, the device is simple and efficient to operate, saves human resources and reduces measurement costs.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A spring-type T-beam camber full-process measurement device includes a measuring head, an adjustable slide rail, a pedestal, a bracket, a base, a directional pulley, and a full-process data processing system. The measuring head is located below the slide rail and mounted on the slide rail. Both ends of the slide rail are fixedly connected to the pedestal, the pedestal is fixedly connected to the top of the bracket, the bottom of the bracket is fixedly connected to the base, and a directional pulley is installed at the bottom of the base.

[0007] The measuring head includes a telescopic protective shell, a spring and a directional small pulley. The telescopic protective shell consists of an upper shell and a lower shell. The upper shell is fixedly connected to the upper part of the spring, and the lower shell is fixedly connected to the lower part of the spring. The directional small pulley is installed at the bottom of the lower shell. When working, the directional small pulley rolls on the top of the T beam.

[0008] The full-process data processing system includes an optical encoder, a photoelectric sensor, a signal processing circuit board, a microcontroller and a data display screen. The optical encoder is fixedly connected to the lower shell plane of the telescopic protective shell, and the photoelectric sensor is fixed to the uppermost end of the lower shell of the telescopic protective shell and passes through the slide groove of the upper shell; the signal processing circuit board and the microcontroller are also fixed on the lower shell plane, and the data display screen is installed on the lower shell plane.

[0009] Furthermore, the optical encoder is welded to the cylindrical support body, which is welded to the lower shell plane of the telescopic protective shell. The photoelectric sensor is welded to the uppermost end of the lower shell of the telescopic protective shell. The signal processing circuit board is welded to the external facade of the microcontroller, which is welded to the lower shell plane. The bottom of the data display is hinged to the lower shell plane.

[0010] Furthermore, the slide rail is an adjustable slide rail, and the main body and the adjustable part are connected by a slider and a slide groove, so that the length of the slide rail can be freely adjusted during operation.

[0011] Preferably, the upper shell is welded to the upper part of the spring, the lower shell is welded to the spring, and the directional pulley is welded to the bottom of the lower shell.

[0012] The upper part and the lower part of the bracket are respectively threadedly connected to the support platform and the base through a first nut and a second nut.

[0013] The directional pulley is threadedly connected to the lower part of the base through bolts.

[0014] The beneficial effects of the utility model are mainly manifested in:

[0015] (1) Efficiently obtain the value of the camber. Currently, when evaluating the camber of beams and slabs, the inspection personnel of construction units, supervision companies and quality inspection and supervision agencies usually use a feeler gauge or vernier caliper to measure the distance between the center point of the arc surface of the beam and slab base and the center point of the arc surface of the bottom surface of the T-beam after the steel bundle is tensioned, and use this reading as the basis for evaluating whether the camber of the T-beam is qualified. However, this method is cumbersome to operate, has low verification efficiency, and the accuracy of the measurement results is poor. The device only needs to move the measuring head on the slide rail and automatically adjust the height of the measuring head according to the actual camber value of the T-beam. Through the full-process data processing system, the actual camber value of the concrete T-beam can be obtained.

[0016] (2) Accurate measurement results. The commonly used measurement and evaluation method at construction sites is to read the distance between the center point of the pedestal arc surface and the center point of the beam slab bottom arc surface. However, since the true beam slab camber can only be obtained when the pedestal pre-camber at the bottom of the T-beam is set to zero, the camber often fails to meet the requirements. The measuring device of this device is mainly installed on a horizontal slide rail, thereby avoiding the interference of the pedestal pre-camber on the measurement results, obtaining the true value of the camber more accurately, and further verifying whether it meets the engineering standards.

[0017] (3) Fully automatic acquisition of the camber value. The traditional beam and slab camber assessment method relies on manual operation. The distance between the center point of the arc surface of the beam and slab base and the center point of the arc surface of the bottom surface of the T-beam is measured by a feeler gauge or a vernier caliper, and the reading needs to be recorded manually. This method is not only complicated to operate, but also easily affected by human errors. The device of the present invention realizes the automatic measurement and data processing of the camber value of the whole process through the full-process data processing system. During the movement of the measuring head along the horizontal slide rail, the device automatically completes the real-time detection and data conversion of the camber, ensuring the accuracy of the camber measurement without the need for manual intervention throughout the process.

[0018] (4) It has strong adaptability and can be recycled. The device is easy to move and can measure the camber value of concrete T-beams of different spans by adjusting the length of the slide rail, with high utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] Reference Figures 1 to 7 A spring-type T-beam camber full-process measuring device includes a measuring head 1, an adjustable slide rail 2, a support 3, a bracket 4, a base 5, a directional pulley 6 and a full-process data processing system 8.

[0029] In the measuring head 1, 101 is a telescopic protective shell, which consists of an upper shell and a lower shell. The upper shell is welded to the upper part of the spring 102, the lower shell is welded to the lower part of the spring 102, and the directional pulley 103 is welded to the bottom of the lower shell. When working, the directional pulley 103 rolls on the top of the T beam, and the telescopic protective shell 101 will move up and down linearly with the contraction of the spring.

[0030] The ends of the adjustable rails 2 are welded to the three bases, and the main body and the adjustable part are connected by sliders and slide grooves, so that the length of the rails can be freely adjusted during operation.

[0031] The upper and lower parts of the bracket 4 are respectively connected to the support 3 and the base 5 by the first nut 701 and the second nut 702.

[0032] The directional pulley 6 is connected to the lower part of the base 5 by bolts.

[0033] In the full-process data processing system 8, the optical encoder 801 is welded to the cylindrical support, which is in turn welded to the lower shell surface of the telescopic protective shell 101. The photoelectric sensor 802 is welded to the uppermost end of the lower shell of the telescopic protective shell 101 and passes through a slot in the upper shell. The signal processing circuit board 803 is welded to the exterior facade of the microcontroller 804, which is welded to the lower shell surface. The bottom of the data display screen 805 is hinged to the lower shell surface. During operation, the full-process data processing system 8 is tightly connected to the lower shell surface of the telescopic protective shell 101 and moves together. When the photoelectric sensor 802 moves along the slot, it scans the grating stripes on the optical encoder 801 line by line, generating a corresponding photoelectric signal. This photoelectric signal is processed by the signal processing circuit board 803 and converted into a digital signal. The microcontroller 804 receives and processes this digital signal, converting it into position information and storing this data in the microcontroller's built-in memory. Ultimately, the desired camber data is displayed on the data display screen 805.

[0034] The implementation process of this embodiment is as follows:

[0035] Step 1: Install the device. Figure 7As shown, the adjustable slide rail spring type prestressed concrete beam camber measuring device is placed on both sides of the concrete T-beam 11 to be measured, so that the lower end of the measuring head 1 of the device is close to the upper part of the concrete T-beam 11, and the extension direction of the slide rail is kept parallel to the front of the concrete T-beam 11. The adjustable slide rail 2 is adjusted so that its length is consistent with the length of the concrete T-beam 11, and then the directional pulley 6 is fixed to the ground.

[0036] Step 2: Camber Verification. After installation is complete, move the measuring head 1 on the adjustable slide rail 2. The measuring head 1, relying on spring 102, moves up and down according to the actual camber value. The actual camber value of the prestressed concrete T-beam is displayed on the data display screen 805 via the full-process data processing system 8. This allows technicians to quickly and accurately obtain the camber value, facilitating the recording of project data.

[0037] The embodiments of this specification are merely examples of implementations of the utility model and are provided for illustrative purposes only. The scope of protection of this utility model should not be considered limited to the specific forms described in these embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by ordinary technicians in this field based on the concept of this utility model.
