Description

Technical Field

[0001] The utility model relates to the field of highway construction acceptance devices, in particular to an adjusting mechanism and an acceptance device with the same. Background Art

[0002] Highway construction acceptance devices are a class of equipment and tools used to inspect and confirm whether the quality of highway construction meets the design specifications and standards. Their main function is to conduct various quality inspections during and after construction to ensure the durability, safety, and performance of the highway.

[0003] Chinese Patent with the authorization announcement number CN221548328U discloses an acceptance device for urban highway construction supervision, including a base. An acceptance instrument is arranged on the base. A vertical rod is fixedly connected under the base. A first fixed seat is fixedly installed on the outer surface of the vertical rod. A first support rod is rotatably installed on the first fixed seat. One end of the first support rod is fixedly connected with a connection block. One end of the connection block is fixedly connected with a second support rod. A moving block is slidably installed inside the second support rod. A connecting rod is arranged between the connection block and the moving block. One end of the moving block is fixedly connected with a support rod. The bottom end of the support rod is hinged with a support seat. In this utility model, by adjusting the length of the support rod extending out of the second support rod, it can adapt to sloping or uneven ground, avoiding the acceptance instrument being placed obliquely, resulting in inaccurate acceptance data and affecting the acceptance result.

[0004] However, this device still has deficiencies: when using this device, the height of the acceptance instrument is adjusted manually, so the operation is relatively cumbersome and complex. And when using this device, the angle of the acceptance instrument cannot be adjusted. If acceptance in other directions is required, the flexibility of using this device is reduced. Content of the Utility Model

[0005] The purpose of the utility model is to address the problem of relatively complex height adjustment in the background art, and propose an adjusting mechanism and an acceptance device with the same.

[0006] The utility model proposes an adjusting mechanism, including:

[0007] A fixed base;

[0008] A support column, which is arranged on the fixed base;

[0009] A lifting assembly, which is arranged on the support column. The lifting assembly includes a mounting plate; the mounting plate is slidably arranged on the support column;

[0010] A placement plate, which is rotatably arranged on the mounting plate. A rotating assembly for driving the placement plate to rotate is arranged on the mounting plate;

[0011] And an acceptance instrument, which is arranged on the placement plate.

[0012] Preferably, the lifting assembly further includes:

[0013] a driving device, which is arranged on the support column;

[0014] a first mounting column, which is rotatably arranged in the support column and connected to the driving device;

[0015] a gear, which is arranged on the first mounting column;

[0016] and a rack, which is slidably arranged in the support column and meshes with the gear, and the mounting plate is connected to the rack.

[0017] Preferably, a limiting plate for limiting the rack is arranged on the rack, and the limiting plate is fitted with the support column.

[0018] Preferably, the rotating assembly includes:

[0019] a second mounting column, which is rotatably arranged on the mounting plate;

[0020] a ring, which is arranged on the mounting plate;

[0021] a ratchet wheel, which is arranged on the second mounting column and located inside the ring;

[0022] and a pawl, which is slidably arranged on the ring and meshes with the tooth grooves on the ratchet wheel.

[0023] Preferably, a spring is arranged on the ring, and the pawl is connected to the spring.

[0024] The present utility model also provides an acceptance device, including the above-mentioned adjusting mechanism.

[0025] Compared with the prior art, the present utility model has the following beneficial technical effects:

[0026] By providing the lifting assembly, the height can be automatically adjusted according to different acceptance standards and terrain conditions, ensuring the accuracy and consistency of measurement; the rapid height adjustment can reduce the complexity of on-site height adjustment of the equipment by the staff and improve the efficiency of construction acceptance; by providing the rotating assembly, the orientation of the acceptance instrument can be adjusted to adapt to different measurement requirements and construction conditions, improving the flexibility of the acceptance work.

Detailed implementation manners

[0031] Embodiment 1

[0033] Rollers 6 are provided on the four sides of the bottom of the fixed base 1; the support column 2 is provided on the fixed base 1; the lifting assembly is provided on the support column 2, and the lifting assembly includes a mounting plate 3; the mounting plate 3 is slidably provided on the support column 2; the placing plate 4 is rotatably provided on the mounting plate 3, a rotating assembly for driving the placing plate 4 to rotate is provided on the mounting plate 3, and the mounting plate 3 is a square plate; the acceptance instrument 5 is provided on the placing plate 4.

[0034] As Figure 2 shown, the lifting assembly further includes a driving device, a first mounting column 8, a gear 9 and a rack 10; the driving device is provided on one side of the support column 2, and the driving device is selected as a servo motor 7; the first mounting column 8 is rotatably provided in the support column 2 and connected to the output shaft of the servo motor 7; the gear 9 is provided on the first mounting column 8; the rack 10 is slidably provided in the support column 2 and meshes with the gear 9, the mounting plate 3 is connected to the top end of the rack 10, a limit plate 11 for limiting the rack 10 is provided at the bottom end of the rack 10, the limit plate 11 is fitted with the support column 2, and a hollow structure for accommodating the lifting assembly is provided on the support column 2. The lifting assembly can automatically adjust the height according to different acceptance standards and terrain conditions to ensure the accuracy and consistency of measurement.

[0035] Embodiment 2

[0036] For the adjustment mechanism and the acceptance device having the same proposed by the present utility model, compared with Embodiment 1, the structure of the rotating assembly is further described in detail in this embodiment.

[0037] As Figure 3As shown in the figure, the rotating assembly includes a second mounting post 14, a circular ring 12, a ratchet wheel 13 and a pawl 16; a hollow part for accommodating the rotating assembly is provided on the mounting plate 3, and the second mounting post 14 is rotatably arranged on the mounting plate 3 and connected to the placing plate 4; the circular ring 12 is arranged on the mounting plate 3; the ratchet wheel 13 is arranged on the second mounting post 14 and located inside the circular ring 12; the pawl 16 is rotatably arranged on the circular ring 12 and meshes with the tooth grooves on the ratchet wheel 13, a spring 15 is arranged on the circular ring 12, the pawl 16 is connected to the spring 15, and a cavity for accommodating the spring 15 is provided on the circular ring 12. The rotating assembly can help the acceptance instrument 5 maintain the correct measurement angle and adapt to different construction environments.

[0038] In summary, when the present invention is in use, when it is necessary to adjust the angle of the acceptance instrument 5, the placing plate 4 is manually rotated, so as to drive the ratchet wheel 13 and the second mounting post 14 to rotate. The pawl 16 can limit the ratchet wheel 13, thereby preventing the placing plate 4 from rotating automatically. When it is necessary to adjust the height of the acceptance instrument 5, the servo motor 7 is turned on, so as to drive the first mounting post 8 and the gear 9 to rotate, and then drive the rack 10, the mounting plate 3, the placing plate 4 and the acceptance instrument 5 to move upward, reducing the complexity of manual operation. Quickly adjusting the height of the acceptance instrument 5 can reduce the complexity of the on-site height adjustment of the equipment by the staff and improve the efficiency of construction acceptance.
