[0001] This utility model belongs to the field of measuring device technology, specifically relating to a bridge construction measuring device. Background Technology

[0002] Bridges are generally structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. Building a bridge requires various surveying tasks. However, manual measurements are prone to errors. Therefore, in most cases, workers need to use surveying instruments to conduct precise and meticulous measurements and layout, providing strong data support for the project construction.

[0003] When workers measure bridges, the slope of the bridge surface makes it difficult to place the measuring instrument stably, which affects the measured data. To address this problem, we propose a bridge construction measuring device. Utility Model Content

[0004] The purpose of this invention is to provide a bridge construction surveying device to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A bridge construction surveying device includes a support platform, a measuring instrument mounted on the upper end of the support platform, a rotating disk rotatably sleeved on the lower end of the support platform, a support rod threadedly connected to the middle of the lower end of the rotating disk, a sleeve rod slidably provided on the outer side of the support rod, a base rotatably provided on the lower end of the sleeve rod, support components provided on the outer side of both the support rod and the sleeve rod, and a locking component provided between the support rod and the sleeve rod.

[0007] The support assembly includes an I-shaped ring. The lower end of the rotating disk has an annular groove. The I-shaped ring is rotatably disposed inside the annular groove. A connecting ring sleeved on the outside of the support rod is threaded onto the inner wall of the I-shaped ring. An installation ring sleeved on the outside of the support rod is fixed to the lower end of the connecting ring. A plurality of evenly distributed installation grooves are provided at the lower end of the installation ring. An auxiliary support rod is rotatably disposed inside each installation groove. A sliding groove is provided at the end of each auxiliary support rod near the sleeve rod. An extension support rod is slidably disposed inside the sliding groove. An adjustment assembly is provided between the auxiliary support rod and the extension support rod. A support plate is provided at the lower end of the extension support rod.

[0008] Furthermore, the adjustment assembly includes a locking block, and an adjustment bolt is rotatably provided on the lower side of one of the back-to-back ends of each of the extension rods. The locking block is rotatably connected to one end of the adjustment bolt that extends into the slide groove, and the extension rod has several locking slots that match the locking block.

[0009] Furthermore, the locking assembly includes a locking ring, which is sleeved on the outside of the support rod. The upper end of the sleeve rod has several evenly distributed grooves, and the outside of the sleeve rod is threadedly connected to the inner wall of the locking ring.

[0010] Furthermore, each of the auxiliary support rods has a number of evenly distributed stops fixed at one end near the sleeve rod.

[0011] Furthermore, each of the auxiliary support rods has a protective block fixed on the upper side of the end near the sleeve rod, which abuts against the outside of the support rod.

Detailed Implementation

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1:

[0025] like Figures 1-6 As shown, a bridge construction surveying device includes a support platform 100, a measuring instrument 101 mounted on the upper end of the support platform 100, a rotating disk 102 rotatably mounted on the lower end of the support platform 100, a support rod 103 threadedly connected to the middle of the lower end of the rotating disk 102, a sleeve rod 104 slidably mounted on the outer side of the support rod 103, a base 105 rotatably mounted on the lower end of the sleeve rod 104, support components are provided on the outer sides of both the support rod 103 and the sleeve rod 104, and a locking component is provided between the support rod 103 and the sleeve rod 104.

[0026] The support assembly includes an I-shaped ring 106. The lower end of the rotating disk 102 has an annular groove. The I-shaped ring 106 is rotatably disposed inside the annular groove. The inner wall of the I-shaped ring 106 is threaded with a connecting ring 107 sleeved on the outside of the support rod 103. The lower end of the connecting ring 107 is fixed with an installation ring 108 sleeved on the outside of the support rod 103. The lower end of the installation ring 108 has several evenly distributed installation grooves 109. An auxiliary support rod 110 is rotatably disposed inside each installation groove 109. Each auxiliary support rod 110 has a sliding groove 111 at one end near the sleeve rod 104. An extension support rod 112 is slidably disposed inside the sliding groove 111. An adjustment assembly is provided between the auxiliary support rod 110 and the extension support rod 112. A support piece 113 is provided at the lower end of the extension support rod 112.

[0027] The support platform 100 can be equipped with a measuring instrument 101, which can measure data of the bridge to assist in bridge construction. The rotating disk 102 can make the support platform 100 and the measuring instrument 101 rotate synchronously, thereby adjusting the detection direction of the measuring instrument 101. The support rod 103 and the sleeve rod 104 can both support the rotating disk 102. At the same time, the height of the measuring instrument 101 can be adjusted by releasing the locking component and sliding the support rod 103. The base 105 can rotate to make the base 105 in close contact with the inclined ground. The support component can help the measuring instrument 101 stand upright on the ground and prevent the measuring instrument 101 from tipping over. By releasing the adjustment component, the extension support rod 112 can slide along the slide groove 111, thereby lengthening the supporting auxiliary support rod 110 to facilitate the support of the measuring instrument 101. The connecting ring 107 can be threadedly connected to the I-shaped ring 106 to facilitate the storage of the auxiliary support rod 110, which makes it convenient for workers to carry.

[0028] When measuring during bridge construction: First, ensure the base 105 is firmly abutted against the inclined bridge deck. Then, straighten the measuring instrument 101 and rotate the I-shaped ring 106 to disengage the connecting ring 107 from the I-shaped ring 106. This allows the operator to move the support assembly up and down. Next, open each auxiliary support rod 110 to the surrounding area and sequentially trigger the locking assembly to release the locking between the auxiliary support rod 110 and the extension support rod 112. This allows the extension support rod 112 to slide out of the groove 111 of the auxiliary support rod 110. Finally, after each support piece 113 is inserted into the bridge deck, fix the auxiliary support rod 110 and the extension support rod 112 together again. This provides auxiliary support for the measuring instrument 101 on the inclined bridge deck, ensuring more accurate measurement data.

[0029] In this embodiment, the base 105 is tightly abutted against the inclined bridge surface, and then the locking assembly is released, allowing the extension rod 112 to slide inside the slide groove 111. Finally, the support piece 113 at the lower end of the extended rod 112 is moved to the inserted bridge surface, and the locking assembly is closed, thus achieving support for the inclined bridge surface of the measuring instrument 101, which facilitates subsequent bridge construction.

[0030] Example 2:

[0031] Based on Embodiment 1, further explanation will be given of other components on the measuring device, such as... Figures 2-6 As shown, the adjustment assembly includes a locking block 200, and each extension rod 112 has an adjusting bolt 201 rotatably mounted on the lower side of one end facing away from each other. The locking block 200 and the end of the adjusting bolt 201 that extends into the slide groove 111 are rotatably connected. The extension rod 112 has several slots 202 that match the locking block 200.

[0032] The locking assembly includes a locking ring 203, which is sleeved on the outside of the support rod 103. The upper end of the sleeve rod 104 has several evenly distributed grooves, and the outside of the sleeve rod 104 is threadedly connected to the inner wall of the locking ring 203.

[0033] Each auxiliary support rod 110 has a number of evenly distributed stop blocks 204 fixed at one end near the sleeve rod 104.

[0034] Each auxiliary support rod 110 has a protective block 205 fixed on the upper side of the end near the sleeve rod 104, which abuts against the outside of the support rod 103.

[0035] The upper end of the rotating disk 102 is provided with several evenly distributed limiting grooves 206, and the upper end of the support platform 100 is provided with a through groove 207 corresponding to any limiting groove 206. The through groove 207 and each limiting groove 206 are provided with a movable groove 208 that communicates with each other. A limiting block 209 is slidably provided inside the movable groove 208.

[0036] In this embodiment, turning the adjusting bolt 201 can cause the locking block 200 to disengage from the slot 202, allowing the operator to slide the extension rod 112, thus increasing the total length of the extension rod 112 and the auxiliary rod 110. When the extension rod 112 moves to the appropriate position, turning the adjusting bolt 201 again will cause the locking block 200 to engage with the corresponding slot 202, stopping the extension rod 112 from sliding and facilitating support for the measuring instrument 101.

[0037] Tighten the locking ring 203 and then lift it upwards to release the fixation between the support rod 103 and the sleeve rod 104. This allows the operator to slide the support rod 103 inside the sleeve rod 104, thereby adjusting the height of the measuring instrument 101. When the measuring instrument 101 is moved to the appropriate position, tighten the locking ring 203 again. The locking ring 203 can press against the upper outer side of the sleeve rod 104. Since the upper outer side of the sleeve rod 104 has several grooves, it can tightly abut against the outer side of the support rod 103, thus fixing the support rod 103 and preventing the measuring instrument 101 from sliding down and affecting its use.

[0038] Each stop 204 can prevent the extension rod 112 from disengaging from the slide groove 111.

[0039] When each auxiliary support rod 110 is retracted to the outside of the support rod 103, each protective block 205 will first abut against the outside of the support rod 103. This can prevent the auxiliary support rod 110 and the extension support rod 112 from colliding with the support rod 103, causing damage to the auxiliary support rod 110 and the extension support rod 112, and affecting the support of the measuring instrument 101.

[0040] Lift the limiting block 209 upwards so that it slides into the moving groove 208 located in the through groove 207. This allows the support platform 100 to rotate, indirectly driving the measuring instrument 101 to rotate. When it reaches the appropriate position, release the limiting block 209 so that it slides into the moving groove 208 in the corresponding limiting groove 206. This fixes the support platform 100 and the rotating disk 102 together, preventing the measuring instrument 101 from shaking and affecting the measurement data.

[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
