Description

TECHNICAL FIELD

[0001] The utility model relates to asphalt mixture density experimental equipment. BACKGROUND

[0002] Asphalt pavement refers to various types of pavements constructed by mixing road asphalt material into mineral materials. The asphalt binder improves the ability of the paving granules to resist the damage of driving and natural factors to the pavement, making the pavement flat, less dusty, water-resistant and durable.

[0003] Traditional asphalt concrete releases a large amount of carbon dioxide and other harmful gases in the production, construction and maintenance links, which has a negative impact on the environment that cannot be ignored. As a new type of road building material, green low-carbon emulsified asphalt binder can effectively reduce the adverse effects on the environment during road construction. Therefore, in-depth study of the performance, preparation process and application in actual engineering of emulsified asphalt binder has a positive significance for promoting the sustainable development of road engineering.

[0004] Currently, the research on emulsified asphalt binder mainly focuses on its basic properties, modification technology, engineering application, etc. Specifically, researchers have in-depth discussed the key properties of the material such as stability, durability, and application range through experiments, simulations, and field tests, and a series of application verification has been carried out in actual road engineering.

[0005] During the construction of asphalt pavement, compaction is an essential construction link for highway construction. After compaction, the components of the mixture can fully contact to form the stable structure required for construction, reduce the deformation of the roadbed surface, greatly improve the bearing capacity and strength of the roadbed and pavement, and enhance the stability and water resistance of the pavement. During highway construction, if the pavement is not subjected to sufficient compaction, it may lead to quality problems such as cracks, ruts, and subsidence, and even cause large-scale shear failure of the pavement. Therefore, compaction degree detection is an important indicator in highway quality detection, which directly reflects the serviceability and safety performance of the highway.

[0006] The compaction degree detection has the following technical problems:

[0007] First, when conducting asphalt mixture density experiments, the test sample is directly grabbed by the staff and placed into the mesh basket in the low-temperature constant-temperature overflow water tank. After the test sample is soaked, it is grabbed from the water. When the test sample is taken out of the low-temperature constant-temperature overflow water tank, it needs to be wiped dry within a certain time for the next operation (referring to the authorized announcement number CN222082244U patent file, a low-temperature constant-temperature overflow water tank auxiliary lifting device);

[0008] Second, the square basket cannot stably accommodate samples of various sizes, and during the lifting of the basket, the samples can slide to one corner or one side of the basket due to their own gravity and the shaking of the basket, so that the basket is inclined, affecting the stability and accuracy of detection. Utility model content

[0009] The utility model solves the technical problem of how to enable the basket to stably accommodate samples of various sizes.

[0010] To solve the above technical problem, the utility model provides the following technical scheme: a green low-carbon type emulsified asphalt detection auxiliary lifting device, which comprises a support installed on an overflow water tank, a winch installed on the support, a cable wound on the winch, and a basket installed at the tail end of the cable, wherein the basket is in an inverted prism shape, the basket comprises a prism-shaped frame and a turnover door hinged to one side of the frame, the bottom of the turnover door is hinged to the bottom of the frame, the top of the turnover door is provided with a locking pin, and the top of the frame is provided with a lock catch matched with the locking pin; the three side walls of the frame and the turnover door are provided with mesh plates.

[0011] An operator opens the turnover door, puts samples into the basket, closes the turnover door again, and locks the turnover door by matching the locking pin with the lock catch. Since the basket is in an inverted prism shape, it is wide at the top and narrow at the bottom, so that samples of a larger size are accommodated at the upper position of the basket, and samples of a smaller size are accommodated at the lower position of the basket. Whether the samples are of a larger size or a smaller size, they can be accommodated at the central position of the basket, i.e. the central position of the basket from front to back and left to right, so that the samples can be stably accommodated in the basket and displacement of the samples in the square basket from left to right, front to back and vice versa is avoided.

[0012] The lock catch is hinged to the frame through a lock catch hinge shaft, the lock catch is provided with a U-shaped clamping groove, and the locking pin can be matched with the U-shaped clamping groove. When the turnover door is closed, the turnover door is turned upward, the locking pin is clamped into the U-shaped clamping groove, then the lock catch is turned upward, the opening of the U-shaped clamping groove faces upward, and thus the locking pin is limited in the U-shaped clamping groove.

[0013] One side of the lock catch hinge shaft is provided with an elastic gasket, and the other side of the lock catch hinge shaft is provided with a locking nut. An operator turns the locking nut to cause axial displacement of the lock catch hinge shaft, the lock catch body abuts against the elastic gasket, and the elastic gasket abuts against the frame, so that a large resistance is required for turning the lock catch, and the lock catch and the locking pin are prevented from being automatically separated.

[0014] The locking pins are arranged on the left and right sides of the turnover door, and the frame is provided with a lock catch matched with the pair of locking pins.

[0015] The cable is provided with a spring scale. An operator can know the weight of the samples in real time through the value displayed by the spring scale.

[0016] The winch is installed on the top support plate of the 7-shaped support, the top support plate is installed on the stand column of the support, and the base at the bottom of the stand column is fixedly installed on the overflow water tank.

[0017] The green low-carbon type emulsified asphalt detection auxiliary lifting device has the following technical effects:

[0018] First, the net basket is provided with a turnover door, and the sample is convenient to take and place;

[0019] Second, the net basket is in an inverted prism shape, can stably accommodate samples with different sizes, and can center the sample;

[0020] Third, the spring scale is directly arranged on the cable, so that the operator can observe the weight of the sample at any time, whether before or after the sample enters the overflow water tank; the weight of the sample before entering the overflow water tank and the weight of the sample after coming out of the overflow water tank can be used to preliminarily judge the density of the sample; of course, this is a preliminary judgment, and after the sample is dried, the sample is transferred to a special instrument for detection.

[0021] In summary, the auxiliary lifting device can stably drop the sample into the low-temperature constant-temperature overflow water tank for immersion and stably lift the sample. BRIEF DESCRIPTION OF DRAWINGS

[0037] One side of the lock catch hinge shaft 441 is provided with an elastic pad 443, and the other side of the lock catch hinge shaft is provided with a locking nut 444.

[0038] As Figure 2 , the locking pins 43 are arranged on the left and right sides of the flip door 42, and the frame 41 is provided with a lock catch 44 matched with the pair of locking pins.

[0041] The operator opens the turnover door 42, puts the sample into the mesh basket 40, and then closes the turnover door.
