Abstract
A road base layer compactness detection sampling device comprises a supporting plate and supporting legs positioned below the supporting plate. A motor is arranged on the supporting plate, a driving gear is connected on a rotating shaft of the motor and connected with a driven rack rod vertically arranged in the middle of the supporting plate in a meshed manner, a sampling cylinder is arranged at the lower end of the driven rack rod, discharging holes are uniformly formed in the periphery of the sampling cylinder, a protective jacket is fixedly connected at the lower end of the supporting plate, the driven rack rod is arranged in the protective jacket, a guide sleeve is fixedly connected at the lower end of the protective jacket, the sampling cylinder is arranged in the guide sleeve, the inner diameter of the guide sleeve is matched with the outer diameter of the sampling cylinder, a rolling wheel is hinged to the lower end of each supporting leg, and a storage positioning hole and an advance positioning hole are formed in the lower end of each supporting leg. The road base layer compactness detection sampling device is convenient to operate, stable in structure and small in vibration.
Description
Technical field
The utility model relates to construction of the highway testing tool, is specially a kind of road base layer degree of compaction and detects sampler.
Background technology
For many years in highway engineering construction, the sampling method of its road base layer, subbase degree of compaction (sand replacement method) adopts ancient mode of operation always, by manually operating with heavy simple and crude instruments such as hammer, screwdriver, flat chisels, with regard to whole process, need artificial many (general 2～3 people), with duration (20～30 minutes), sample moisture content is easily lost, and large to perturbing property of the soil body, and sampling hole perisporium is rough, sampling weak effect, accuracy is not good enough, Chinese patent 201120579524.2 discloses a kind of construction of the highway and has detected sampler by road base layer degree of compaction, the both forward and reverse directions that rotates drive driving gear by controlling the both forward and reverse directions of motor rotates, and then drive the driven rack bar that is engaged with connection to move up and down, can utilize the sampling tube that is connected to driven rack bar end to realize sampling, but the vibrations of the sampling tube of sampler lower end are large in actual applications, easily there is the situation of skew, bring in operation very big inconvenience, and when carrying out next step operation, sampler carrying, carry all very inconvenient, increased associative operation personnel's the amount of labour.
Utility model content
The technical problem that the utility model solves is to provide a kind of road base layer degree of compaction to detect sampler, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of road base layer degree of compaction detects sampler, comprise gripper shoe and the supporting leg that is positioned at gripper shoe below, the top of described gripper shoe is provided with motor, in the rotating shaft of described motor, be connected with driving gear, described driving gear be arranged in the middle of described gripper shoe and vertically arranged driven rack bar is connected with a joggle, the lower end of described driven rack bar is provided with on the circumference of sampling tube described in sampling tube and is evenly provided with dumping pit; Described gripper shoe lower end is fixedly connected with protective sleeve, and described driven rack bar is placed in protective sleeve, and described protective sleeve lower end is fixedly connected with a fairlead, and described sampling tube is placed in fairlead, and the internal diameter of fairlead matches with the external diameter of sampling tube; The lower end of described supporting leg is hinged with a scroll wheel, is also provided with takes in locating hole and the locating hole of advancing in the lower end of described supporting leg, in use, coordinates the alignment pin on supporting leg to be fixed scroll wheel.
Further, the lower end of described fairlead is provided with the hole coordinating with dumping pit.
Compared with prior art, the utility model is easy to operate, and Stability Analysis of Structures is vibrated littlely, can give operating personnel with very large facility.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
