Description

Technical Field

[0001] This utility model relates to the field of instrumentation technology, and in particular to a Beckman beam dial indicator holder. Background Technology

[0002] According to JTG 3450-2019 "Specifications for Field Testing of Subgrade and Pavement", bridges require regular Benkelman beam deflection testing. This testing requires Benkelman beam dial indicators and their holders. Current Benkelman beam deflection testing uses generic dial indicator holders; however, these holders have the following drawbacks: the screws securing the dial indicator lack fixed ends, making them prone to loosening and falling off during actual testing, and they are often lost after disassembly. This prevents the dial indicator from being securely mounted on the holder, directly compromising the accuracy of the test data during Benkelman beam deflection testing. The data fails to accurately reflect the deflection condition of the subgrade and pavement, thus affecting the reliability of road engineering quality assessment. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a Beckman beam dial indicator stand with a stable structure and parts that are not easily lost, which is suitable for Beckman beam deflection detection.

[0004] To address the aforementioned problems, this utility model proposes a Beckman beam dial indicator bracket, comprising a bracket base, a bracket, a fixing component, and a locking assembly.

[0005] The bracket is vertically mounted on the bracket base, and the fixing component is slidably connected to the bracket. One side of the fixing component is provided with a through hole, and a fastening post is connected to the through hole. The end of the fastening post can abut against the surface of the bracket to fix the fixing component to the bracket.

[0006] The fixing component has at least two clamping pieces on its side, and each clamping piece has a clamping groove on its opposite side. The ends of the clamping pieces have opposite locking holes, and the locking holes are equipped with locking components to fix the clamping grooves.

[0007] As an improvement to the above technical solution, the locking assembly includes a locking stud and a locking nut, the locking stud passing through the locking hole, and the locking stud having locking ends at both ends;

[0008] The locking stud has a smooth surface on its outer middle part, and the two ends of the middle part of the locking stud have threaded structures. The diameter of the locking end is larger than the diameter of the locking hole.

[0009] As an improvement to the above technical solution, the thread structure on the two ends of the middle part of the locking stud has opposite directions.

[0010] As an improvement to the above technical solution, the bracket passes through the fixing component, the end of the fastening stud extends through the through hole into the inner cavity of the fixing component, and a fixing block is rotatably connected to one end of the fastening stud in the inner cavity of the fixing component, and the fixing block can abut against the bracket.

[0011] As an improvement to the above technical solution, the fixing block and the bracket are provided with wavy protrusions on their two opposite sides.

[0012] As an improvement to the above technical solution, a sliding tube is provided on one side of the fixing component, a sliding rod is inserted into the sliding tube and slidably connected to the sliding rod, a fixing plate is provided at the end of the sliding rod outside the sliding tube, and the clamping piece is provided on the fixing plate.

[0013] As an improvement to the above technical solution, the inner wall of the slide tube is provided with an installation cavity, and a positioning rod is provided in the installation cavity; one end of the positioning rod extends through the installation cavity to the outside of the slide tube, and the other end of the positioning rod extends through the installation cavity to the inside of the slide tube; the slide tube is provided with a plurality of positioning grooves arranged at predetermined intervals, and the end of the positioning rod can extend into the positioning groove.

[0014] The positioning rod is provided with an abutment plate on its side inside the mounting cavity, and a spring is provided between the abutment plate and the inner wall of the mounting cavity to prevent the positioning rod from moving away from the positioning groove.

[0015] As an improvement to the above technical solution, the spring is sleeved on the positioning rod, one end of the spring is connected to or abuts against the abutment plate, and the other end is connected to or abuts against the inner wall of the mounting cavity.

[0016] As an improvement to the above technical solution, the positioning rod is provided with a handle at one end outside the slide tube.

[0017] The following are the beneficial effects of implementing this utility model:

[0018] This utility model includes a support base, a support, a fixing component, and a locking assembly. The support is mounted on the support base, and the fixing component is slidably connected to the support. The fixing component is fixed to the support via fastening posts at through holes. The fixing component has at least two clamping plates on its side, and each clamping plate has a locking hole. A locking assembly is provided at the locking holes to clamp the clamping plates onto the Beckman beam dial indicator. This increases the friction between the Beckman beam dial indicator and the support, thereby ensuring the Beckman beam dial indicator is stably fixed to the dial indicator holder.

[0019] Secondly, the locking assembly includes a locking stud and a locking nut. The locking stud has locking ends at both ends, which limit the movement and prevent the locking stud from falling off during operation.

[0020] Finally, the inner cavity of the fixing component is provided with a fixing block that is connected to the locking post, and the side of the fixing block opposite to the bracket is provided with a wave-shaped protrusion to increase the friction between the fixing component and the bracket and reduce the shaking between the fixing component and the bracket during the testing process.

[0021] The Beckman beam dial gauge has a stable overall structure. Conducting Beckman beam deflection testing can accurately reflect the deflection status of the roadbed and pavement, thus improving the reliability of road engineering quality assessment. Attached Figure Description

[0026] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 4 As shown, this utility model embodiment provides a Beckman beam dial indicator bracket, including a bracket base 1, a bracket 2, a fixing component 3, and a locking component 4.

[0028] This embodiment of the invention improves the locking structure to ensure that the parts of the Beckermann beam dial indicator are not easily dislodged.

[0029] Specifically, the bracket 2 is vertically mounted on the bracket base 1, and the fixing component 3 is slidably connected to the bracket 2. A through hole 31 is provided on one side of the fixing component 3, and a fastening post 32 is connected to the through hole 31. The end of the fastening post 32 can abut against the surface of the bracket 2 so that the fixing component 3 is fixed to the bracket 2.

[0030] The fixing component 3 has at least two clamping pieces 33 on its side. Each clamping piece 33 has a clamping groove 331 on its opposite side. The ends of the clamping pieces 33 have opposite locking holes. The locking holes are equipped with locking components 4 so that the clamping grooves 331 can fix the Beckerman beam dial indicator.

[0031] During operation, after adjusting the fixing component 3 to a suitable height, tighten the fixing post 32 so that the end abuts against the surface of the bracket 2 to achieve locking. After placing the Beckman beam dial indicator in the clamping groove 331, use the locking component 4 at the locking hole to lock the clamping piece 33, thereby clamping the Beckman beam dial indicator with the clamping piece 33.

[0032] This invention increases the friction between the Beckman beam dial indicator and its frame, thus ensuring the Beckman beam dial indicator is stably fixed to the frame. This allows for a more accurate reflection of the deflection condition of the roadbed and pavement, improving the reliability of road engineering quality assessment.

[0033] Since this is used for bridge pavement inspection, the outdoor pavement experiences slight vibrations during inspection. Conventional locking components are prone to loosening and loss due to vibration, requiring the use of other components for locking, which affects the accuracy of the inspection. Preferably, the locking component 4 includes a locking stud 41 and a locking nut 42. The locking stud 41 passes through the locking hole, and both ends of the locking stud 41 are provided with locking ends 43.

[0034] The locking stud 41 has a smooth surface on its outer side in the middle, and the locking stud 41 has threaded structures on both ends in the middle. The diameter of the locking end 43 is larger than the diameter of the locking hole.

[0035] Locking ends 43 are provided at both ends of the locking stud 41. The locking ends 43 limit the locking stud 41 in the locking hole, which can prevent the need to use other locking components due to the locking stud falling off or being lost, thus avoiding the problem of inaccurate detection. In addition, the outer side of the middle part of the locking stud 41 is provided with a smooth surface. The smooth surface is provided to prevent the threads from rubbing against the locking hole during clamping and adjustment, which could cause damage to the locking hole.

[0036] More preferably, the threaded structures on the two ends of the middle portion of the locking stud 41 are in opposite directions. Because the threaded structures are in opposite directions, the locking nuts can be brought closer together by turning the locking stud until they lock the clamping piece.

[0037] The conventional fixing component 3 achieves locking by generating friction through the contact between its fastening post 32 and the smooth surface of the bracket 2. However, the contact area between the end of the fastening post 32 and the bracket 2 is small, resulting in minimal friction. During road surface inspection, the fixing component 3 is prone to relative slippage with the bracket 2, affecting the accuracy of the Beckman beam dial indicator.

[0038] Preferably, the bracket 2 passes through the fixing component 3, and the end of the fastening post 32 extends into the inner cavity of the fixing component 3 through the through hole 31. A fixing block 321 is rotatably connected to one end of the fastening post 32 in the inner cavity of the fixing component 3, and the fixing block 321 can abut against the bracket 2. The increased contact area between the fixing block 321 and the bracket 2 improves the stability between the bracket 2 and the fixing component 3.

[0039] More preferably, the fixing block 321 and the bracket 2 have wavy protrusions on their opposite sides. Because the fixing block 321 and the bracket 2 have wavy protrusions on their opposite sides, the surfaces of the fixing block and the bracket can engage with each other, further increasing the friction between the fixing component 3 and the bracket 2.

[0040] The fastening post 32 is provided with a turning handle 322 at one end outside the fixing component 3.

[0041] In conventional dial indicator stands, the distance between the Beckman beam dial indicator and the stand cannot be adjusted, increasing the difficulty of adjusting its position during field use.

[0042] Preferably, a sliding tube 34 is provided on one side of the fixing component 33, and a sliding rod 35 is inserted into the sliding tube 34 and slidably connected to the sliding rod 35. A fixing plate 36 is provided at the end of the sliding rod 35 outside the sliding tube 34, and the clamping piece 33 is provided on the fixing plate 36. When it is necessary to adjust the distance between the dial indicator and the slider, the sliding rod 35 can be pulled to slide.

[0043] More preferably, the inner wall of the slide tube 34 is provided with a mounting cavity 341, and a positioning rod 5 is provided in the mounting cavity 341; one end of the positioning rod 5 extends outward through the mounting cavity 341 to the outside of the slide tube 34, and the other end of the positioning rod 5 extends inward through the mounting cavity 341 to the inside of the slide tube 34; the slide rod 35 is provided with a plurality of positioning grooves 351 arranged at predetermined intervals, and the end of the positioning rod 5 can extend into the positioning groove 351;

[0044] The positioning rod 5 is provided with an abutment plate 51 on its side inside the mounting cavity 341. A spring 52 is provided between the abutment plate 51 and the inner wall of the mounting cavity 341 to prevent the positioning rod 5 from moving away from the positioning groove 351.

[0045] Preferably, the spring 52 is sleeved on the positioning rod 5, one end of the spring 52 is connected to or abuts against the abutment plate 51, and the other end is connected to or abuts against the inner wall of the mounting cavity 341.

[0046] Preferably, the positioning rod 5 is provided with a handle 53 at one end outside the slide tube 34.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
