[0001] The present application relates to the field of bridge construction measurement and control, and in particular to a detection device for variable-section pier formwork. Background Art

[0002] In bridge construction, piers include vertical piers, variable-section piers, and column piers. Variable-section piers, as key structural components, have a direct impact on the safety and stability of the building due to their design and construction quality. Formwork construction for variable-section piers is a critical step in ensuring their quality. However, due to their complex shapes and diverse dimensions, traditional formwork inspection methods face numerous challenges in practical application.

[0003] Existing detection technologies often rely on surveyors to use total stations or RTK positioning, which is not only relatively complicated to operate but also poses certain safety risks when locating high piers. In addition, when assembling multiple sections of pier body formwork, errors are prone to occur, causing the upper position formwork to deviate significantly and the measurement results to not meet the standards. Adjusting the formwork again not only wastes a lot of time, manpower and material resources, but also conventional pier body formwork is heavy and large in size, making it difficult to accurately control the offset of its adjustment.

[0004] Therefore, there is an urgent need to provide a detection device that can solve the problems in the prior art of complicated measurement steps, difficult operation, and time-consuming and labor-intensive variable-section pier templates. Summary of the Invention

The motorized rotary wheel and the telescopic rod are respectively mounted on adjacent sides of the device box. The steel tape measure is fixed to the motorized rotary wheel, and the end of the steel tape measure is connected to the laser rangefinder. During measurement, the tape measure extends from the end of the telescopic rod and then droops, while the laser rangefinder droops to a position adjacent to the bottom of the variable-section pier column formwork.

[0007] In one embodiment, a fixing assembly is provided on the bottom surface of the device box, and the device box is detachably mounted on the top surface of the variable-section pier column formwork through the fixing assembly.

[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] An embodiment of the present application provides a detection device for a variable-section pier column formwork, which can solve the problems of the existing variable-section pier column formwork having complicated measurement steps, difficult operation, and time-consuming and labor-intensive.

[0028] In one embodiment, please refer to Figure 1 , is a schematic diagram of a detection device for a variable-section pier column formwork in an embodiment of the present application, such as Figure 1 As shown, the inspection device for the variable-section pier column formwork includes a device box 1 and a measuring assembly 2. The device box 1 can be used to place the measuring assembly 2. When the measuring device is measuring, part of the measuring assembly needs to extend out of the device box. Therefore, the device box can also serve as a support point for the measuring assembly 2. The measuring assembly 2 is used to measure the variable-section pier column formwork to detect whether the variable-section pier column formwork has reached the standard position.

[0029] When using this detection device, the device box 1 is generally placed on the top surface of the variable-section pier formwork. Since the space inside the device box 1 is relatively ample, the measurement assembly 2 can be placed inside the device box 1. The measurement assembly 2 includes a motorized wheel 21, a steel tape measure 22, a laser rangefinder 23, and a telescopic rod 24 that can extend from the device box 1. The motorized wheel 21 and the telescopic rod 24 are respectively mounted on adjacent sides of the device box 1. The steel tape measure 22 is fixed to the motorized wheel 21, and the end of the steel tape measure 22 is connected to the laser rangefinder 23. During measurement, the tape measure extends along the end of the telescopic rod 24 and then droops, while the laser rangefinder 23 droops to the bottom of the adjacent variable-section pier formwork.

[0030] The electric wheel 21 and the steel tape measure 22 control the extension and retraction of the tape measure. In its initial state (i.e., fully retracted), the telescopic rod 24 is located within the device box 1. When the telescopic rod 24 is in use (i.e., in the process of being extended or fully extended), the device box 1 is provided with a hole through which the telescopic rod 24 can extend. The telescopic rod 24 can extend through this hole. Furthermore, the telescopic rod 24 can be extended in steps or sections until it reaches the desired length (the desired length is determined by the dimensions of the actual variable-section pier formwork). A "channel" for the tape measure to pass through is provided on the telescopic rod 24. This "channel" can be a groove or a through-hole formed in the telescopic rod 24. A laser rangefinder 23 is connected to the end of the tape measure. The two can be bonded, clamped, or threaded together.

[0031] In this embodiment, by placing the device box 1 on the top surface of the variable-section pier column formwork, it is convenient for the detection device to measure the variable-section pier column formwork. The measuring assembly 2 includes an electric wheel 21, a steel tape 22, a laser rangefinder 23, and a telescopic rod 24 that can extend from the device box 1. By placing the measuring assembly 2 inside the device, it is not only possible to prevent the measuring assembly 2 from being lost during transportation, but also to protect them from damage due to bumps. By mounting the electric wheel 21 and telescopic rod 24 on adjacent sides of the device box 1, and fixing the steel tape 22 to the electric wheel 21, with the laser rangefinder 23 connected to the end of the steel tape 22, the electric wheel 21 can be rotated to control the extension and retraction of the tape, so that the tape extends along the extension direction of the telescopic rod 24. The electric wheel 21 and telescopic rod 24 are mounted on adjacent sides of the device box 1, which ensures that they do not interfere with each other during operation and is more conducive to rotating the electric wheel 21 to extend the tape along the telescopic rod 24.

[0032] It should be noted that during measurement, as the telescopic rod 24 extends, the electric wheel 21 also rotates to control the extension of the steel tape measure 22, allowing the two to extend synchronously. When the telescopic rod 24 is extended to the desired length, the electric wheel 21 continues to rotate, while the laser rangefinder 23 has a certain weight. When the telescopic rod 24 stops extending, the laser rangefinder 23, under the action of gravity, drives the tape measure from the extended end of the telescopic rod 24 to move vertically downward until the laser rangefinder 23 reaches the bottom of the adjacent variable-section pier formwork. The inclination of the variable-section pier formwork is calculated by reading the readings of each section of the tape measure and the distance collected by the laser rangefinder 23, and is compared with the design value to determine whether it has reached the specified position. At the end of the measurement, the electric wheel 21 rotates in the opposite direction, and the tape measure begins to retract. At this time, the laser rangefinder 23, driven by the tape measure, first returns to the end of the extended end of the telescopic rod 24, and then retracts synchronously with the telescopic rod 24 into the device box 1.

[0033] In this embodiment, by using the measuring device to perform the above-mentioned detection steps, it is possible to effectively detect whether the variable-section pier column formwork has reached the standard position, thereby improving measurement efficiency and reducing the consumption of manpower and material resources. At the same time, it is also suitable for the installation of multi-section variable-section pier column formwork, which is conducive to timely adjustment.

[0034] Furthermore, in one embodiment, if Figure 1 As shown, the bottom surface of the device box 1 is provided with a fixing component 3, and the device box 1 is detachably mounted on the top surface of the variable-section pier column formwork through the fixing component 3. In this embodiment, by providing the fixing component 3 on the bottom surface of the device box 1, the device box 1 is stably mounted on the top surface of the variable-section pier column formwork, preventing the detection device from falling due to unstable center of gravity or tilting of the device box 1 during measurement, which will affect the measurement results; and by detachably mounting the fixing component 3 on the top surface of the variable-section pier column formwork, it is more convenient to disassemble and install the device box 1, thereby improving work efficiency. Among them, the fixing component 3 can be a clamp 31 or a hoop, etc.

[0035] Furthermore, in one embodiment, if Figure 1 As shown, the fixing assembly 3 includes two clamping jaws 31, and the distance between the two clamping jaws 31 is adjustable. In this embodiment, the fixing assembly 3 includes two clamping jaws 31. By setting the distance between the two clamping jaws 31 to be adjustable, it can be clamped for different types of variable-section pier column formwork, and can also be clamped for different installation stages of the same variable-section pier column formwork, which is simple and convenient to use.

[0036] Furthermore, in one embodiment, if Figure 1 As shown, the clamping ends of the two clamping jaws 31 are each provided with a clamping notch, which is serrated and matches the clamping notch of the two clamping jaws 31. In this embodiment, by providing the clamping ends of the two clamping jaws 31 with a serrated shape, the stability of the clamping jaws 31 on the variable-section pier column formwork is increased, and the clamping jaws 31 are effectively prevented from slipping or falling off during the process of clamping the variable-section pier column formwork. The serrated shape of the clamping notch allows the clamping force to be more evenly distributed across the surface of the clamped object, avoiding damage to the variable-section pier column formwork caused by excessive local pressure.

[0037] Furthermore, in one embodiment, if Figure 1 As shown, rubber gaskets are provided at the clamping ends of the two clamping jaws 31. In this embodiment, by providing rubber gaskets at the clamping ends of the two clamping jaws 31, since the surface of the rubber gaskets has a certain friction coefficient, the friction between the clamping jaws 31 and the variable-section pier column formwork can be increased, making the clamping more stable.

[0038] Furthermore, in one embodiment, if Figure 1As shown, a number of leveling screws 4 are evenly arranged between the bottom surface of the device box 1 and the fixing assembly 3. In this embodiment, by evenly arranging a number of leveling screws 4 between the bottom surface of the device box 1 and the fixing assembly 3, the device box 1 can be adjusted in the horizontal and vertical directions, ensuring that the device box 1 can be stably fixed in the predetermined position after installation, avoiding shaking or tilting caused by unevenness of the variable-section pier formwork or installation errors.

[0039] Furthermore, in one embodiment, if Figure 1 As shown, a bubble level is provided on the top surface of the device box 1. In this embodiment, the presence of a bubble level on the top surface of the device box 1 provides a visual indicator of whether the device box 1 is level. When the device box 1 is perfectly level, the bubble within the bubble level will remain centered. If the device box 1 tilts, the bubble will shift to one side, prompting the operator to make adjustments. This instant feedback mechanism facilitates high-precision installation of the device box 1.

[0040] Furthermore, in one embodiment, if Figure 1 As shown, the top surface of the telescopic rod 24 is provided with a slot for the tape measure to pass through, and the end of the extended end of the telescopic rod 24 is provided with a stopper 241. In this embodiment, the slot provided on the top surface of the telescopic rod 24 for the tape measure to pass through prevents displacement of the tape measure, ensuring accurate tape measurement. Furthermore, the stopper 241 provided at the extended end of the telescopic rod 24 ensures smooth retraction of the tape measure after measurement, preventing it from curling up.

[0041] Furthermore, in one embodiment, if Figure 1 As shown, after the test is completed, the telescopic rod 24 is in a retracted state, the measuring tape passes through the telescopic rod 24, and the laser rangefinder 23 abuts against the stop 241. In this embodiment, after the test is completed, the telescopic rod 24 is in a retracted state. At this time, the measuring tape still passes through the telescopic rod 24. Because the extended end of the telescopic rod 24 is provided with a stop 241, the stop 241 can block the laser rangefinder 23 from passing through, causing it to abut against the stop 241. By retracting the telescopic rod 24, the measuring tape, and the laser rangefinder 23 into the device box 1, the volume and space occupied by the detection device when not in operation can be reduced, while also making the structure more compact and easier to carry and store.

[0042] Furthermore, in one embodiment, if Figure 1As shown, a plumb bob 5 is detachably mounted on the bottom surface of the laser rangefinder 23. In this embodiment, the detachable plumb bob 5 increases the weight of the laser rangefinder 23, allowing the tape measure to remain taut during measurement and improving measurement accuracy. The plumb bob 5 is detachably mounted, for example, via a screw connection or snap-on fastening. When the detection device is not in use, the plumb bob 5 can be removed from the detection device to reduce its weight and facilitate its transportation.

[0043] In this embodiment, a device box 1 is provided on the top surface of the variable-section pier formwork; a measuring assembly 2 is provided in the device box 1, and the measuring assembly 2 includes an electric wheel 21, a steel tape measure, a laser rangefinder 23, and a telescopic rod 24 that can be extended from the device box 1. The electric wheel 21 and the telescopic rod 24 are respectively installed on adjacent sides of the device box 1, the steel tape measure is fixed on the electric wheel 21, and the end of the steel tape measure is connected to the laser rangefinder 23; when measuring, the tape measure extends out of the end along the telescopic rod 24 and then droops, and the laser rangefinder 23 droops to the bottom of the adjacent variable-section pier formwork. Through this embodiment, when the detection device is measuring, the tape measure will record the length of each section, record the extended length of the telescopic rod 24 as X1, record the descending length of the laser rangefinder 23 as H, and record the distance from the bottom of the variable-section template measured by the laser rangefinder 23 as X2, so as to calculate the inclination of the variable-section template as (X1-X2): H, and then compare the obtained inclination with the design value to determine whether the variable-section template reaches the standard position. The use of this detection device can accurately determine whether the variable-section template is qualified, is simple to operate, and is more accurate, which can well solve the problems in the prior art that the measurement steps of the variable-section pier template are cumbersome, difficult to operate, and time-consuming and labor-intensive.
