Description

Technical Field

[0001] This utility model relates to the field of rockfill particle size measurement technology, specifically a lightweight rockfill particle size measurement device. Background Technology

[0002] Particle size measurement of riprap is a crucial aspect of quality control in earth-rock dams, roadbeds, retaining walls, and other engineering projects. Its purpose is to ensure that the particle size distribution of the riprap meets design requirements.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1

[0022] like Figure 1-2As shown, this utility model provides a technical solution: a lightweight riprap particle size measuring device, including a measuring cylinder 1, which is a tapered cylinder that is wider at the top and narrower at the bottom. An observation groove 2 is provided on the measuring cylinder 1, which also facilitates the removal of riprap material placed in the measuring cylinder 1, preventing the material from getting stuck inside. The observation groove 2 is positioned towards the handheld lever 7, making it easier to observe and read the diameter value 3 when operating the handheld extension lever 8. The observation groove 2 has diameter values ​​3 corresponding to different areas of the measuring cylinder 1 on one side. A fixing ring 4 is connected to the top of the measuring cylinder 1. Two positioning plates 5 are installed on one side of the fixing ring 4, and a rotating shaft 6 is installed between the two positioning plates 5. The rotating shaft 6 is connected to one end of the handheld rod 7. A fixing bolt 9 is installed on one of the positioning plates 5, and the fixing bolt 9 is connected to the round hole on the handheld rod 7. An extension rod 8 is slidably provided on the other end of the handheld rod 7, and the handheld rod 7 slides in the slot in the extension rod 8. The handheld rod 7 and the extension rod 8 are fixed by bolts. Pulling the extension rod 8 on the handheld rod 7 increases the length of the handheld part. By holding the extension rod 8, the single pile of stone to be measured is slid into the inlet of the measuring cylinder 1. The pile of stone will fall into the measuring cylinder 1 at the same diameter. The diameter value 3 of the pile of stone can be quickly read through the observation slot 2. After the measurement is completed, the measuring cylinder 1 can be tilted and the single pile of stone can be taken out immediately.

[0023] Example 2

[0024] Based on Example 1, such as Figure 3 and Figure 4 As shown, another technical solution is provided. The measuring cylinder 1 is divided into an upper cylinder 101 and a lower cylinder 102, with the top end of the lower cylinder 102 corresponding to the bottom end of the upper cylinder 101. A collar 103 is provided at the top end of the lower cylinder 102, and the collar 103 is fitted onto the outer wall of the bottom end of the upper cylinder 101 for fixed installation between the upper cylinder 101 and the lower cylinder 102. Bolts 104 are installed on both sides of the collar 103, and the bolts 104 are connected to the round holes opened on the outer wall of the bottom end of the upper cylinder 101. This method allows for the installation or removal of the lower cylinder 102 as needed. When not measuring smaller-sized riprap, the lower cylinder 102 can be removed, and only the upper cylinder 101 needs to be used. Furthermore, the combined design of the upper cylinder 101 and the lower cylinder 102 allows the lower cylinder 102 to be stored inside the upper cylinder 101 when not in use. Figure 4 As shown, the device is easier to carry and more portable.

[0025] The operational steps for this application are as follows:

[0026] Pull the extension rod 8 on the handheld rod 7 to increase the length of the handheld part. Through the handheld extension rod 8, slide the single pile of stone to be measured into the inlet of the measuring cylinder 1. The pile of stone will fall into the measuring cylinder 1 into a part of the same diameter. The diameter value 3 of the pile of stone can be quickly read through the observation groove 2. After the measurement is completed, the measuring cylinder 1 can be tilted and the single pile of stone can be taken out immediately.
