Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for road compaction testing, specifically to a road compaction degree testing device. Background Technology

[0002] Compaction degree is one of the key indicators for testing the construction quality of roadbeds and pavements. It characterizes the density after on-site compaction. The higher the compaction degree, the greater the density, and the better the overall performance of the material. Compaction degree is usually measured by methods such as the ring cutter method, sand cone method, and nuclear density meter method. Among them, the sand cone method uses a uniform amount of sand to replace the volume of the test hole, and the sand cone cylinder is the main tool for measuring compaction degree using the sand cone method.

[0003] In the specific operation of the sand filling method, the sand filling cylinder needs to be placed on the weighing scale manually first, the tare is removed and then the specified amount of standard sand is poured in. After weighing, the sand filling cylinder is moved to the pre-dug test hole, the sand filling cylinder is opened and the standard sand is filled into the test hole. Finally, the remaining standard sand in the sand filling cylinder is weighed to complete the compaction test.

[0004] In practice, the above-mentioned operation method requires weighing the sand-filling cylinder before and after use, and also requires moving the sand-filling cylinder back and forth between the weighing scale and the testing hole. This not only hinders the improvement of work efficiency, but also increases the workload of the staff, resulting in low efficiency in road compaction testing. Utility Model Content

[0005] The purpose of this invention is to provide a road compaction testing device to solve the above-mentioned problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The road compaction testing device provided by this utility model includes a base plate, side plates, and a sand filling cylinder body. The base plate is placed flat and has a sand filling hole vertically opened in the middle of the base plate. The side plates are vertically fixed on both sides of the top surface of the base plate. The sand filling cylinder body is placed between the two side plates and is coaxially suspended above the sand filling hole. Lifting guide components are combined on both sides of the sand filling cylinder body. The sand filling cylinder body is detachably combined between the side plates on both sides by means of the lifting guide components, so as to guide and correct the vertical movement of the sand filling cylinder body by means of the lifting guide components.

[0008] A weighing and detection component is provided between the two side plates, above the bottom plate and below the sand filling cylinder body, to weigh the sand filling cylinder body before and after sand filling.

[0009] Preferably, the base plate is a rectangular flat plate with vertical anchoring holes at all four corners. An anchoring rods with top ends larger than the diameter of the anchoring holes are coaxially inserted into each anchoring hole. A bubble level is installed on the front of the top of the base plate.

[0010] Preferably, the lower part of the sand filling cylinder body is provided with a toggle valve for controlling the opening and closing state of the bottom opening, and an annular stabilizing flange is coaxially and flatly fixed on the outer periphery of the bottom end of the sand filling cylinder body.

[0011] Preferably, a positioning sleeve is coaxially and vertically fixed on the top surface of the base plate at the position around the sand filling hole, and the inner circumference of the positioning sleeve and the outer circumference of the stabilizing flange are coaxially clearance fit.

[0012] Preferably, each of the lifting guide components includes a guide groove and a guide screw. The top surface of the side plates on both sides is vertically provided with the guide groove, and the guide groove is a through groove in the horizontal direction. The guide screw is horizontally fixed on both sides of the middle of the periphery of the sand filling cylinder body by a fixing sleeve, and the guide screw passes through the corresponding guide groove in a sliding fit. The portion of the guide screw located between the corresponding side plate and the periphery of the sand filling cylinder body is coaxially fixed with a limiting collar, and the limiting collar is in contact with the inner side of the corresponding side plate.

[0013] Preferably, the portion of the guide screw extending outward from the corresponding side plate is coaxially engaged with a locking nut, and all locking nuts are hand-tightened knurled nuts.

[0014] Preferably, the outer ends of the guide screws on both sides, which are far apart from each other, are coaxially fixed by a connecting sleeve to facilitate gripping the handle for applying force.

[0015] Preferably, the guide grooves are all vertically arranged waist-shaped elongated grooves, with the top of the guide grooves open and the bottom of the guide grooves close to the bottom of the side plate.

[0016] Preferably, the weighing and detection components include a support wing plate and a weighing body. The support wing plate is fixedly placed horizontally on the lower inner side of the side plate, and the weighing body is placed horizontally between the tops of the support wing plates on both sides. At the same time, the weighing platform on the top surface of the weighing body is suspended below the bottom of the sand filling cylinder body.

[0017] Preferably, the top surface of each of the support wing plates is covered with a rubber anti-slip pad, and the bottom side of each weighing scale body is attached to the top surface of the anti-slip pad placed on the corresponding side.

[0018] In the practical application of the aforementioned road compaction testing device for road compaction testing, since the lifting guide assembly is assembled on both sides of the sand filling cylinder body, after the base plate is moved to align with the sand filling hole and the hole to be tested, the vertical movement of the sand filling cylinder body can be guided and corrected by the guide screw of the lifting guide assembly sliding vertically along the guide groove. This facilitates the descent and movement of the sand filling cylinder body to align with the sand filling hole before sand filling, eliminating the need for repeatedly moving the sand filling cylinder body to align with the hole to be tested. This design improves the efficiency of compaction testing. Because the guide screw of the lifting guide assembly slides vertically along the guide groove, the vertical height of the sand-filling cylinder body can be quickly adjusted without misalignment between the sand-filling cylinder body and the sand-filling hole. Furthermore, by lifting the sand-filling cylinder body and placing the weighing body of the testing and weighing assembly on top of the support wing plates on both sides, the weighing body can be used to weigh the sand-filling cylinder body before and after sand filling. This eliminates the need to repeatedly weigh the cylinder body. The weighing operation can be completed after the sand filling cylinder body is placed between the support wing plates on both sides and removed from between the support wing plates on both sides. This eliminates the need to move the sand filling cylinder body back and forth between the weighing scale body and the testing hole, reducing the workload of workers and helping to further improve the efficiency of compaction testing. It should be noted that when the sand filling cylinder body is manually lifted, the distance between its bottom end and the support wing plate should be greater than the thickness of the weighing scale body. This ensures that the weighing scale body can be inserted between the bottom end of the sand filling cylinder body and the top surface of the support wing plate and placed stably on the support base plate. When the weighing body is placed between the top surfaces of the two side plates, the sand filling cylinder body should be gently and slowly placed on the top surface of the weighing platform of the weighing body to avoid excessive impact. Since the top of the guide groove is open, the sand filling cylinder body can be quickly disassembled and assembled between the two side plates by means of the guide screw to separate and slide in from the top of the guide groove. This facilitates the subsequent storage and maintenance of the sand filling cylinder body after it is separated between the two side plates, and also facilitates the quick assembly of the sand filling cylinder body between the two side plates for sand filling operation.

[0019] The beneficial effects are as follows: 1. The present invention is equipped with lifting guide components on both sides of the sand filling cylinder body. After the bottom plate is moved to the sand filling hole and aligned with the hole to be tested, the vertical movement of the sand filling cylinder body can be guided and corrected by the guide screw of the lifting guide component sliding vertically along the guide groove. This makes it easier to lower the sand filling cylinder body to align with the sand filling hole vertically before sand filling. There is no need to repeatedly move the sand filling cylinder body to align with the hole to be tested, which helps to improve the compaction detection efficiency.

[0020] 2. By using the guide screw of the lifting guide assembly to slide vertically along the guide groove, the vertical height of the sand filling cylinder body can be quickly adjusted without causing misalignment between the sand filling cylinder body and the sand filling hole. Then, by lifting the sand filling cylinder body and placing the weighing body of the detection weighing assembly on the top of the support wing plates on both sides, the weighing body can be used to weigh the sand filling cylinder body before and after sand filling. The weighing operation can be completed simply by repeatedly placing the weighing body between the support wing plates on both sides and removing it from between the support wing plates on both sides. There is no need to move the sand filling cylinder body back and forth between the weighing scale and the detection hole, which reduces the workload of workers and helps to further improve the efficiency of compaction testing.

[0021] 3. The top of the guide groove is open. By using the guide screw to separate and slide into the guide groove from the top, the sand filling cylinder body can be quickly disassembled and assembled between the two side plates. This makes it convenient to store and maintain the sand filling cylinder body after it is separated from the two side plates, and also makes it convenient to quickly assemble the sand filling cylinder body between the two side plates for sand filling operation.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] See Figures 1-6As shown, this utility model provides a road compaction testing device, including a base plate 3, side plates 2, and a sand-filling cylinder body 4. The base plate 3 is placed horizontally, and a sand-filling hole 303 is vertically opened in the middle of the base plate 3. Side plates 2 are vertically fixed on both sides of the top surface of the base plate 3. The sand-filling cylinder body 4 is positioned between the two side plates 2 and is coaxially suspended above the sand-filling hole 303. Lifting guide components 1 are assembled on both sides of the sand-filling cylinder body 4, and the sand-filling cylinder body 4 is guided by... The lifting guide assembly 1 is detachably assembled between the side plates 2 on both sides. It is used to guide and correct the vertical movement of the sand-filling cylinder body 4. Specifically, the lifting guide assembly 1 includes a guide groove 106 and a guide screw 104. The top surface of the side plates 2 on both sides is vertically provided with guide grooves 106, and these guide grooves 106 are through grooves in the horizontal direction. Guide screws 104 are horizontally fixed to both sides of the outer periphery of the sand-filling cylinder body 4 via fixing sleeves 101. All rods 104 slide laterally through the corresponding guide grooves 106. The portion of the guide screw 104 located between the corresponding side plate 2 and the outer periphery of the sand filling cylinder body 4 is coaxially fixed with a limiting collar 102, and the limiting collar 102 is in contact with the inner side of the corresponding side plate 2. The purpose of this arrangement is that, after the base plate 3 is moved to align the sand filling hole 303 with the hole to be tested, the vertical movement of the sand filling cylinder body 4 can be guided and corrected by the guide screw 104 of the lifting guide assembly 1 sliding vertically along the guide groove 106. This facilitates the sand filling cylinder body 4 to descend and move to align vertically with the sand filling hole 303 before sand filling, eliminating the need to repeatedly move the sand filling cylinder body 4 to align with the hole to be tested. At the same time, the vertical height of the sand filling cylinder body 4 can be quickly adjusted by the guide screw 104 of the lifting guide assembly 1 sliding vertically along the guide groove 106, and the sand filling cylinder body 4 and the sand filling hole 303 will not be misaligned during the adjustment process.

[0033] See Figures 1-3As shown, a weighing assembly is installed between the two side plates 2, above the bottom plate 3 and below the sand filling cylinder body 4. This assembly is used to weigh the sand filling cylinder body 4 before and after sand filling. Specifically, each weighing assembly includes a support wing plate 503 and a weighing body 501. Support wing plates 503 are longitudinally fixed to the lower inner side of each side plate 2, and the weighing body 501 is horizontally supported between the tops of the support wing plates 503 on both sides. The weighing platform on the top surface of the weighing body 501 is suspended above the sand filling cylinder. The purpose of this arrangement at the bottom of the cylinder body 4 is that, by lifting the sand filling cylinder body 4 and placing the weighing body 501 of the detection and weighing component on top of the support wing plates 503 on both sides, the weighing body 501 can be used to weigh the sand filling cylinder body 4 before and after sand filling. The weighing operation can be completed simply by repeatedly placing the weighing body 501 between the support wing plates 503 on both sides and removing it from between the support wing plates 503 on both sides, without having to move the sand filling cylinder body 4 back and forth between the weighing scale and the detection hole.

[0034] See Figures 1-6 As shown, the following optimizations have been made to this application. Specifically, the base plate 3 is a rectangular flat plate with vertical anchoring holes 301 at each of the four corners. An anchoring rods 302 with top ends larger than the diameter of the anchoring holes 301 are coaxially inserted into each anchoring hole 301. A bubble level 305 is installed at the front of the top of the base plate 3. With this setting, it is convenient to temporarily fix the base plate 3 by passing the anchoring rods 302 through the anchoring holes 301 and inserting them into the ground until the top ends press against the corners of the base plate 3. Of course, this method is only suitable for use on the ground. Unless necessary, the base plate 3 does not need to be fixed under normal circumstances. At the same time, it is convenient to use the bubble level 305 to clearly indicate the level of the base plate 3, which is convenient for operators to observe and refer to for leveling the base plate. Optionally, the lower part of the sand filling cylinder body 4 is equipped with a toggle valve 401 for controlling the opening and closing of the bottom opening. A ring-shaped stabilizing flange 402 is coaxially and horizontally fixed to the outer periphery of the bottom of the sand filling cylinder body 4. This arrangement facilitates the control of the opening and closing of the bottom opening of the sand filling cylinder body 4 using the toggle valve 401, and also facilitates the stable vertical placement of the sand filling cylinder body 4 using the stabilizing flange 402. Furthermore, a positioning sleeve 304 is coaxially and vertically fixed to the top surface of the base plate 3 around the sand filling hole 303. The inner circumference of the positioning sleeve 304 and the outer circumference of the stabilizing flange 402 are in a coaxial clearance fit. Preferably, the top of the positioning sleeve 304 is lower than the bottom surface of the supporting wing plate 503. This arrangement allows for stable positioning and correction of the sand filling cylinder body 4 when the bottom end of the sand filling cylinder body 4 contacts the top surface of the base plate 3, through the coaxial fit between the stabilizing flange 402 and the positioning sleeve 304.

[0035] See Figures 1-6As shown, the portions of the guide screws 104 extending beyond the corresponding side plates 2 are coaxially engaged with locking nuts 103, and all locking nuts 103 are hand-tightened knurled nuts. This allows for temporary locking and fixing of the position and height of the sand-filling cylinder body 4 by tightening the locking nuts 103 on both sides, pressing them against the outer sides of the side plates 2. Optionally, the outer ends of the guide screws 104 on both sides, which are far apart from each other, are coaxially fixed with handles 107 for easy gripping and force application. This allows workers on both sides to lift the guide screws 104 and slide them vertically along the guide grooves 106 by gripping the handles 107. Furthermore, the guide grooves 106 are all vertically arranged waist-shaped elongated grooves, with the top of the guide grooves 106 open and the bottom of the guide grooves 106 close to the bottom of the side plates 2. This arrangement allows the guide grooves 106 to have a wide range of vertical sliding and also facilitates the disengagement and sliding of the guide screws 104 from the top of the guide grooves 106. Furthermore, the top surface of the support wing plate 503 is covered with a rubber anti-slip pad 502, and the bottom side of the weighing scale body 501 is attached to the top surface of the anti-slip pad 502 placed on the corresponding side. This arrangement makes it easier to place the weighing scale body 501 more stably between the tops of the support wing plates 503 on both sides with the help of the anti-slip pad 502.

[0036] With the above structure, in practical applications for road compaction testing, since lifting guide components 1 are combined on both sides of the sand filling cylinder body 4, after the base plate 3 is moved to align with the sand filling hole 303 and the hole to be tested, the vertical movement of the sand filling cylinder body 4 can be guided and corrected by the guide screw 104 of the lifting guide component 1 sliding vertically along the guide groove 106. This facilitates the descent and movement of the sand filling cylinder body 4 to align with the sand filling hole 303 before sand filling, eliminating the need for repeated movement of the sand filling cylinder body 4 to align with the hole to be tested, thus improving the compaction testing efficiency. To measure efficiency, the vertical height of the sand filling cylinder body 4 can be quickly adjusted by the vertical sliding of the guide screw 104 along the guide groove 106 via the lifting guide assembly 1, without causing misalignment between the sand filling cylinder body 4 and the sand filling hole 303 during the adjustment process. Then, by lifting the sand filling cylinder body 4 and placing the weighing body 501 of the weighing assembly on top of the support wing plates 503 on both sides, the weighing body 501 can be used to weigh the sand filling cylinder body 4 before and after sand filling. This only requires repeatedly placing the weighing body 501 on both sides. The weighing operation can be completed after the supporting wing plates 503 at the designated position are removed and then removed from the supporting wing plates 503 at both sides. This eliminates the need to move the sand-filling cylinder body 4 back and forth between the weighing body 501 and the testing hole, reducing the workload of workers and helping to further improve the efficiency of compaction testing. It should be noted that when the sand-filling cylinder body 4 is manually lifted, the distance between its bottom end and the supporting wing plate 503 should be greater than the thickness of the weighing body 501. This ensures that the weighing body 501 can be inserted into the position between the bottom end of the sand-filling cylinder body 4 and the top surface of the supporting wing plate 503 and placed stably on the supporting base plate 3. When the weighing body 501 is placed between the top surfaces of the weighing plates 501, the sand filling cylinder body 4 should be placed gently and slowly on the top surface of the weighing platform of the weighing body 501 to avoid excessive impact. Since the top of the guide groove 106 is open, the sand filling cylinder body 4 can be quickly separated and assembled between the two side plates 2 by means of the guide screw 104 along the guide groove 106 from the top. This makes it convenient to store and maintain the sand filling cylinder body 4 after it is separated between the two side plates 2, and also makes it convenient to quickly assemble the sand filling cylinder body 4 between the two side plates 2 for sand filling operation.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
