Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to a compression resistance detection equipment based on a steel slag pavement substrate. Background Art

[0002] Steel slag is mainly a by-product produced after ironmaking in blast furnaces of steel plants. Steel slag particles have high compressive strength and wear resistance, and can effectively disperse and bear road loads. At the same time, steel slag particles have low expansion and contraction rates, and can maintain good dimensional stability and reduce road cracks. After proper treatment, steel slag particles can be used for paving road base and subbase, showing good engineering performance and economic benefits. The excellent compressive resistance of steel slag particles is the key to ensuring road stability and durability. Scientific testing of compressive resistance is not only the basis for evaluating steel slag quality, but also a prerequisite for ensuring engineering quality.

[0003] When testing the compressive performance of the steel slag pavement base, it is generally necessary to prefabricate multiple groups of steel slag pavement base samples for comparative analysis. However, it is time-consuming and labor-intensive to manually prefabricate multiple groups of steel slag pavement base samples, resulting in low efficiency when prefabricating multiple groups of steel slag pavement base samples. At the same time, when testing and analyzing the steel slag pavement base samples, since the steel slag pavement base samples also contain other mixed auxiliary materials such as lime and cement, the compressive performance of the steel slag pavement base samples varies under different temperature and humidity conditions. Therefore, the present application provides a compressive performance testing device based on the steel slag pavement base to meet the needs. Summary of the invention

[0028] like Figures 1 to 14As shown, an embodiment of the present invention provides a compression resistance testing device based on a steel slag pavement substrate, including an installation box 1, a hydraulic cylinder 2 is installed on the top of the installation box 1, a collecting box 20 is installed on the bottom of the installation box 1, a control module 3 is installed on the surface of one end of the installation box 1, a hot air blower 4 is installed through one side of the top of the installation box 1, a spray device 5 is installed through the other side of the top of the installation box 1, a rotating rod 6 is nested and installed on the inner wall of the installation box 1, a motor 7 is installed on the end of the rotating rod 6 that extends out of the installation box 1, a mounting plate 8 is installed on the middle surface of the rotating rod 6, the number of rotating rods 6, motors 7 and mounting plates 8 are all set to two groups, and the two groups of rotating rods 6, motors 7 and mounting plates 8 are symmetrically installed on the installation box 1, a flip assembly 9, and a flip assembly 9 is installed on the top of the mounting plate 8. Component 9, the flip component 9 is used to transfer and exchange the manufactured steel slag pavement base samples, the sliding component 10, the sliding component 10 is installed on the inner wall of the top of the mounting plate 8, the sliding component 10 is used to perform an extrusion test on the side of the steel slag pavement base sample in the flip component 9, the gravity component 11, the gravity component 11 is installed at the bottom of the flip component 9, the gravity component 11 is used to push out the steel slag pavement base sample in the flip component 9 to complete the transfer and exchange, the locking component 12, the locking component 12 is installed on one side of the gravity component 11, the locking component 12 is used to lock and switch the state of the gravity component 11, the sliding component 10 is located on both sides of the bottom of one group of extrusion boxes 91 in the flip component 9, the gravity component 11 is located at the bottom of the flip component 9, and the locking component 12 is located on both sides of the gravity component 11.

[0029] By setting up the flip component 9, the detection and transportation of the steel slag pavement base samples can be realized, and the compaction resistance of the steel slag pavement base samples in two different environments can be simulated and tested. By setting up the sliding component 10, the side compaction resistance of the steel slag pavement base samples can be tested. By setting up the gravity component 11, the rotation effects of the two groups of rotating rods 6 and the mounting plate 8 are coordinated, and the steel slag pavement base samples in the extrusion box 91 and the transfer box 96 are exchanged and transferred through the extrusion block 111 and the push plate 116. By setting up the locking component 12, the counterweight block 115 can have both counterweight and support functions, thereby improving the functional applicability of the counterweight block 115.

[0030] like Figure 6 to Figure 7As shown, the flip assembly 9 includes an extrusion box 91, and the number of the extrusion boxes 91 is set to three groups. The bottom end of one of the three extrusion boxes 91 is connected to an elastic telescopic rod 92, and the elastic telescopic rod 92 is elastically installed on the top of one of the mounting plates 8. The remaining two groups of extrusion boxes 91 in the three groups of extrusion boxes 91 are symmetrically installed on both sides of the top of one of the mounting plates 8. The flip assembly 9 also includes a push plate 93, which is installed at the bottom of the hydraulic cylinder 2, and an extrusion plate 94 is installed at the bottom of the push plate 93. The number of the extrusion plates 94 is set to three, and the remaining two extrusion plates 94 of the three extrusion plates 94 are installed on both sides of the bottom of the push plate 93 through an elastic telescopic rod 95. The flip assembly 9 also includes a transfer box 96, and the number of the transfer boxes 96 is set to three groups. Three groups of transfer boxes 96 are installed on the top of another group of mounting plates 8.

[0031] The operator pours the steel slag particle mixture into the three groups of extrusion boxes 91 respectively, and then the operator controls the hydraulic cylinder 2 through the control module 3 to start the hydraulic cylinder 2. After the hydraulic cylinder 2 is started, it drives the push plate 1 93 to slide synchronously. While the push plate 1 93 slides, it drives the three extrusion plates 94 to slide downward synchronously. The bottom end of one of the extrusion plates 94 approaches and contacts the top surface of the steel slag particle mixture in one group of extrusion boxes 91, and the other two extrusion plates 94 approach and contact the top surfaces of the steel slag particle mixture in the other two groups of extrusion boxes 91. Under the continuous sliding action of the push plate 1 93, the push plate 1 93 drives the three extrusion plates 94 at the bottom to synchronously extrude the steel slag particle mixture in the three groups of extrusion boxes 91, and extrude the steel slag particle mixture in the three groups of extrusion boxes 91 into steel slag pavement base samples. When one of the extrusion plates 94 squeezes the steel slag particle mixture in one group of extrusion boxes 91 into place, the hydraulic cylinder 2 drives the push plate 1 93 to continue sliding. Under the continuous squeezing action of the push plate 1 93 and the three extrusion plates 94, one of the extrusion plates 94 pushes the elastic telescopic rod 1 92 at the bottom end of one group of extrusion boxes 91 to contract, causing this group of extrusion boxes 91 to slide. At the same time, under the contact force between the two extrusion plates 94 and the surface of the steel slag particle mixture in the other two groups of extrusion boxes 91, the elastic telescopic rod 2 95 at the top end of this group of extrusion plates 94 contracts. Subsequently, the control module 3 controls one of the motors 7 to start, and after starting, the motors 7 drive one of the rotating rods 6 and the mounting plate 8 to rotate synchronously in the forward or reverse direction. The mounting plate 8 drives the three extrusion boxes 91 to rotate synchronously in the forward or reverse direction while rotating, and makes the three extrusion boxes 91 approach and align with the hot air blower 4 or the spraying device 5. The operator can start the hot air blower 4 or the spraying device 5 according to the detection requirements, and heat or humidify the steel slag pavement substrate samples in the three extrusion boxes 91 through the hot air blower 4 or the spraying device 5, so as to simulate the use environment of the steel slag pavement substrate under two weather conditions of high temperature and high humidity; Subsequently, this group of motors 7 continues to drive one group of rotating rods 6 and mounting plates 8 to rotate synchronously in the forward or reverse direction, so that this group of mounting plates 8 continues to rotate while driving the three groups of extrusion boxes 91 to approach and align with the top ends of the three groups of transfer boxes 96. Subsequently, under the action of gravity, the slag pavement base samples in the three groups of extrusion boxes 91 fall into the transfer boxes 96.

[0032] By setting up an extrusion box 91 and a transfer box 96, and symmetrically arranging two groups of rotating rods 6, motors 7 and mounting plates 8, the detection and transportation of steel slag pavement base samples can be realized. At the same time, three groups of extrusion boxes 91 are used to follow the circular trajectory of one group of mounting plates 8 when rotating. By symmetrically installing spray equipment 5 and hot air blower 4 on both sides of the mounting box 1, when the first compaction resistance test of the steel slag pavement base sample is carried out, the steel slag pavement base sample in the extrusion box 91 is heated or humidified by cooperating with the forward and reverse rotation effect of one group of mounting plates 8, and the compaction resistance of the steel slag pavement base sample in two different environments is simulated. The transfer box 96 is used to perform a secondary test on the steel slag pavement base sample after heating or humidification. At the same time, by arranging three groups of extrusion boxes 91, the detection efficiency of the steel slag pavement base sample is further improved.

[0033] like Figure 8 As shown, the sliding assembly 10 includes a rack 101, the number of which is set to two, and the two racks 101 are installed on both sides of one group of extrusion boxes 91, a flat gear 102 is meshed on one side of the rack 101, the number of which is set to two groups, and the two groups of flat gears 102 are installed on the top inner wall of one group of mounting plates 8, one end of the flat gear 102 is connected to a screw 103, and the other end of the screw 103 is installed at the bottom end of the extrusion box 91, a sliding base 104 is provided on the threaded sleeve at the top of the screw 103, a side extrusion plate 105 is installed at one end of the sliding base 104, and a pressure sensor 106 is nested and installed on the surface of the side extrusion plate 105.

[0034] One group of extrusion boxes 91 slides and drives the rack 101 to slide synchronously. Under the sliding action of the rack 101, the rack 101 engages the flat gear 102 to rotate. The rotation of the flat gear 102 drives the screw 103 to rotate synchronously. Under the rotation action of the screw 103, the sliding base 104 threadedly sleeved on the outer surface of the screw 103 slides along the direction of the screw 103. The sliding base 104 drives the side extrusion plate 105 to contact and squeeze one side of the steel slag pavement base sample while sliding. The side extrusion plate 105 performs compression resistance detection on the steel slag pavement base sample through the surface pressure sensor 106, and sends the obtained data to the control module 3 through an electrical signal.

[0035] By setting the linkage cooperation of the rack 101, the flat gear 102 and the screw 103, utilizing the sliding force of one group of extrusion boxes 91, the side of the steel slag pavement base samples in the other two groups of extrusion boxes 91 are extruded through the side extrusion plate 105, thereby realizing the test of the compaction resistance of the side of the steel slag pavement base samples.

[0036] like Figures 9 to 12 As shown, the gravity component 11 includes an extrusion block 111, and the number of the extrusion blocks 111 is set to three groups. The three groups of extrusion blocks 111 are all nested and installed on the bottom end of the inner wall of the extrusion box 91. The bottom end of the extrusion block 111 is connected to a mounting seat 113 through a bolt 112. The bottom end of the mounting seat 113 is connected to a hydraulic rod 114. The bottom end of the hydraulic rod 114 is installed with a counterweight block 115. The gravity component 11 also includes a push plate 116. The number of the push plates 116 is set to three groups. The three groups of push plates 116 are all nested and installed on the bottom end of the inner wall of the transfer box 96. A pressure sensor 117 is nested and installed on the surface of the push plate 116. The bottom end of the push plate 116 is connected to a counterweight block 118.

[0037] This set of mounting plates 8 drives the three sets of extrusion boxes 91 to rotate synchronously and put them in place. The counterweight block 115 previously located at the bottom of the extrusion box 91 changes its position to the top of the extrusion box 91 under the rotation of the mounting plates 8. Under the action of gravity, the counterweight block 115 slides downward. While the counterweight block 115 slides downward, it drives the extrusion block 111, the bolt 112, the mounting seat 113 and the hydraulic rod 114 to slide downward synchronously. While the extrusion block 111 slides, it pushes out the steel slag pavement base sample in the extrusion box 91. Under the action of gravity, the steel slag pavement base sample after heating or humidification treatment falls into the transfer box 96. When the mounting plate 8 drives the three groups of extrusion boxes 91 to rotate 180 degrees to change to an inverted state, and at the same time cooperates with the sliding action of the counterweight block 115, at this time, the extrusion block 111 is located on the top of the steel slag pavement base sample in the transfer box 96, and the surface of the extrusion block 111 contacts the top of the steel slag pavement base sample (such as Fig.11 As shown), then, the control module 3 controls the hydraulic rod 114 to start, and the hydraulic rod 114 starts to push the mounting seat 113 to slide downward. While the mounting seat 113 slides, the extrusion block 111 is driven by the bolt 112 to contact and squeeze the top of the steel slag pavement base sample in the transfer box 96. At this time, the bottom of the steel slag pavement base sample is in contact with the pressure sensor 2 117 at the top of the push plate 2 116. Through the extrusion effect of the pressure sensor 2 117 and the extrusion block 111, the steel slag pavement base sample after heating or humidification treatment is subjected to a secondary compression resistance test. The operator can remove the bolt 112 and replace the extrusion block 111 of different shapes to test the steel slag pavement base sample. When the compression resistance test is completed, the control module 3 controls the hydraulic rod 114 to slide upward and reset. The hydraulic rod 114 slides while driving the mounting seat 113 to slide upward. While the mounting seat 113 slides, the extrusion block 111 is driven to disengage from the top of the slag pavement base sample through the bolt 112. Then the control module 3 controls another set of motors 7 to start. After starting, this set of motors 7 drives another set of rotating rods 6 and the mounting plate 8 to rotate synchronously. While the other set of mounting plates 8 rotates, it drives the three sets of transfer boxes 96 to rotate synchronously. Under the rotation of the transfer box 96, the positions of the transfer box 96 and the counterweight block 118 are changed. At this time, the counterweight block 118 is located at the top of the transfer box 96. Under the action of gravity, the counterweight block 118 drives the push plate 116 to slide downward. While the push plate 116 slides, the steel slag pavement base sample in the transfer box 96 is pushed out, so that the steel slag pavement base sample falls into the collection box 20, and the tested steel slag pavement base samples are collected centrally.

[0038] By setting a counterweight block 115 and a counterweight block 118, utilizing the effect of gravity and coordinating the rotation effects of the two sets of rotating rods 6 and the mounting plate 8, the steel slag pavement base samples in the extrusion box 91 and the transfer box 96 are exchanged and transferred through the extrusion block 111 and the push plate 116. After the steel slag pavement base samples are transferred to the transfer box 96, the steel slag pavement base samples after heating or humidification treatment are subjected to a secondary test through the cooperation between the hydraulic rod 114, the extrusion block 111 and the pressure sensor 117, so as to further ensure the test effect of the steel slag pavement base samples.

[0039] like Figure 13 to Figure 14 As shown, the locking assembly 12 includes a liquid storage barrel 121, which is installed on both sides of a counterweight block 115, and a piston disc 122 is installed in the internal cavity of the liquid storage barrel 121. The top of the piston disc 122 extends out of the bottom end of the liquid storage barrel 121 and is installed with a counterweight block 3 123. The top of the liquid storage barrel 121 is connected to a liquid inlet barrel 124 through a hose, and the liquid inlet barrel 124 is installed on one side of the counterweight block 115. A piston disc 2 125 is installed in the internal cavity of the liquid inlet barrel 124, and one end of the piston disc 2 125 extends out of the liquid inlet barrel 124 and is installed with a block 126. The surface of the block 126 contacts with a positioning plate 127, and the positioning plate 127 is installed at the bottom end of the extrusion box 91.

[0040] After the counterweight block 115 changes position following the mounting plate 8, the counterweight block 115 slides downward into place under the action of gravity, while the liquid storage barrel 121 and the counterweight block 3 123 synchronously change their positions following the counterweight block 115. At this time, the counterweight block 3 123 is located at the top of the liquid storage barrel 121. Under the action of gravity, the counterweight block 3 123 slides downward and pushes the piston disc 122 to slide downward in the internal cavity of the liquid storage barrel 121. Under the squeezing action of the piston disc 122, the piston disc 122 squeezes the oil at the bottom of the piston disc 122 into the liquid inlet barrel 124 through the hose. Under the continuous squeezing action of the piston disc 122, After the oil enters the liquid inlet barrel 124, it pushes the piston disc 125 to slide downward in the internal cavity of the liquid inlet barrel 124. While the piston disc 125 slides, it drives the block 126 to slide horizontally along the liquid inlet barrel 124. While the block 126 slides, it approaches and contacts the side of the positioning plate 127. When the counterweight block 115 drives the liquid storage barrel 121 and the liquid inlet barrel 124 to slide downward into place, the block 126 slides and contacts the inner wall of the opening on the surface of the positioning plate 127, realizing the clamping effect of the block 126 and the positioning plate 127. Through the clamping effect of the block 126 and the positioning plate 127, an auxiliary support effect is achieved for the counterweight block 115.

[0041] By setting up a liquid storage barrel 121 and a liquid inlet barrel 124, and using gravity through the counterweight block three 123 to achieve oil exchange between the liquid storage barrel 121 and the liquid inlet barrel 124, auxiliary support for the counterweight block one 115 and the hydraulic rod 114 is achieved, and by switching the clamping state between the counterweight block one 115 and the positioning plate 127, the counterweight block one 115 has both counterweight and support functions, thereby improving the functional applicability of the counterweight block one 115.

[0042] The working principle of the technical solution provided by the present invention is as follows: The operator pours the steel slag particle mixture into the three groups of extrusion boxes 91 respectively, and then the operator controls the hydraulic cylinder 2 through the control module 3 to start the hydraulic cylinder 2. After the hydraulic cylinder 2 is started, it drives the push plate 93 to slide synchronously. While the push plate 93 slides, it drives the three extrusion plates 94 to slide downward synchronously. The bottom end of one of the extrusion plates 94 approaches and contacts the top surface of the steel slag particle mixture in one group of extrusion boxes 91, and the other two extrusion plates 94 approach and contact the top surfaces of the steel slag particle mixture in the other two groups of extrusion boxes 91. Under the continuous sliding action of the push plate 93, the push plate 93 drives the three extrusion plates 94 at the bottom to synchronously extrude the steel slag particle mixture in the three groups of extrusion boxes 91, and extrude the steel slag particle mixture in the three groups of extrusion boxes 91 into steel slag pavement base samples.

[0043] When one of the extrusion plates 94 squeezes the steel slag particle mixture in one group of extrusion boxes 91 into place, the hydraulic cylinder 2 drives the push plate 1 93 to continue sliding. Under the continuous extrusion action of the push plate 1 93 and the three extrusion plates 94, one of the extrusion plates 94 pushes the elastic telescopic rod 1 92 at the bottom end of one group of extrusion boxes 91 to contract, causing this group of extrusion boxes 91 to slide. At the same time, under the contact force between the two extrusion plates 94 and the surfaces of the steel slag particle mixture in the other two groups of extrusion boxes 91, the elastic telescopic rod 2 95 at the top end of this group of extrusion plates 94 contracts.

[0044] One group of extrusion boxes 91 slides and drives the rack 101 to slide synchronously. Under the sliding action of the rack 101, the rack 101 engages the flat gear 102 to rotate. The rotation of the flat gear 102 drives the screw 103 to rotate synchronously. Under the rotation action of the screw 103, the sliding base 104 threadedly sleeved on the outer surface of the screw 103 slides along the direction of the screw 103. The sliding base 104 drives the side extrusion plate 105 to contact and squeeze one side of the steel slag pavement base sample while sliding. The side extrusion plate 105 performs compression resistance detection on the steel slag pavement base sample through the surface pressure sensor 106, and sends the obtained data to the control module 3 through an electrical signal.

[0045] Subsequently, the control module 3 controls one of the motors 7 to start, and after starting, this group of motors 7 drives one of the rotating rods 6 and the mounting plate 8 to rotate synchronously in the forward or reverse direction. When the mounting plate 8 rotates, it drives the three groups of extrusion boxes 91 to rotate synchronously in the forward or reverse direction, and makes the three groups of extrusion boxes 91 approach and align with the hot air blower 4 or the spray equipment 5. The operator can start the hot air blower 4 or the spray equipment 5 according to the detection requirements, and heat or humidify the steel slag pavement base samples in the three groups of extrusion boxes 91 through the hot air blower 4 or the spray equipment 5, so as to simulate the use environment of the steel slag pavement base under two weather conditions of high temperature and high humidity.

[0046] Subsequently, this group of motors 7 continues to drive one group of rotating rods 6 and mounting plates 8 to rotate synchronously in the forward or reverse direction, so that this group of mounting plates 8 continues to rotate while driving the three groups of extrusion boxes 91 to approach and align with the top ends of the three groups of transfer boxes 96. Subsequently, under the action of gravity, the slag pavement base samples in the three groups of extrusion boxes 91 fall into the transfer boxes 96.

[0047] This set of mounting plates 8 drives the three sets of extrusion boxes 91 to rotate synchronously and put into place. At the same time, the counterweight block 115 previously located at the bottom of the extrusion box 91 changes its position to the top of the extrusion box 91 under the rotation of the mounting plate 8. Under the action of gravity, the counterweight block 115 slides downward. While the counterweight block 115 slides downward, it also drives the extrusion block 111, bolt 112, mounting seat 113 and hydraulic rod 114 to slide downward synchronously. While the extrusion block 111 slides, it pushes out the steel slag pavement base sample in the extrusion box 91, and under the action of gravity, the steel slag pavement base sample after heating or humidification treatment falls into the transfer box 96.

[0048] After the counterweight block 115 changes position following the mounting plate 8, the counterweight block 115 slides downward into place under the action of gravity, while the liquid storage barrel 121 and the counterweight block 3 123 synchronously change their positions following the counterweight block 115. At this time, the counterweight block 3 123 is located at the top of the liquid storage barrel 121. Under the action of gravity, the counterweight block 3 123 slides downward and pushes the piston disc 122 to slide downward in the internal cavity of the liquid storage barrel 121. Under the squeezing action of the piston disc 122, the piston disc 122 squeezes the oil at the bottom of the piston disc 122 into the liquid inlet barrel 124 through the hose. Under the continuous squeezing action of the piston disc 122, After the oil enters the liquid inlet barrel 124, it pushes the piston disc 125 to slide downward in the internal cavity of the liquid inlet barrel 124. While the piston disc 125 slides, it drives the block 126 to slide horizontally along the liquid inlet barrel 124. While the block 126 slides, it approaches and contacts the side of the positioning plate 127. When the counterweight block 115 drives the liquid storage barrel 121 and the liquid inlet barrel 124 to slide downward into place, the block 126 slides and contacts the inner wall of the opening on the surface of the positioning plate 127, realizing the clamping effect of the block 126 and the positioning plate 127. Through the clamping effect of the block 126 and the positioning plate 127, an auxiliary support effect is achieved for the counterweight block 115.

[0049] Subsequently, the control module 3 controls the hydraulic rod 114 to start, and the hydraulic rod 114 starts to push the mounting seat 113 to slide downward. While the mounting seat 113 slides, the extrusion block 111 is driven by the bolt 112 to contact and squeeze the top of the steel slag pavement base sample in the transfer box 96. At this time, the bottom of the steel slag pavement base sample is in contact with the pressure sensor 2 117 at the top of the push plate 2 116. Through the extrusion effect of the pressure sensor 2 117 and the extrusion block 111, the steel slag pavement base sample after heating or humidification treatment is subjected to a secondary compression resistance test. The operator can remove the bolt 112 and replace the extrusion block 111 of different shapes to test the steel slag pavement base sample.

[0050] When the compression resistance test is completed, the control module 3 controls the hydraulic rod 114 to slide upward and reset. The hydraulic rod 114 slides while driving the mounting seat 113 to slide upward. While the mounting seat 113 slides, the extrusion block 111 is driven to disengage from the top of the slag pavement base sample through the bolt 112. Then the control module 3 controls another set of motors 7 to start. After starting, this set of motors 7 drives another set of rotating rods 6 and the mounting plate 8 to rotate synchronously. While the other set of mounting plates 8 rotates, it drives the three sets of transfer boxes 96 to rotate synchronously. Under the rotation of the transfer box 96, the positions of the transfer box 96 and the counterweight block 118 are changed. At this time, the counterweight block 118 is located at the top of the transfer box 96. Under the action of gravity, the counterweight block 118 drives the push plate 116 to slide downward. While the push plate 116 slides, the steel slag pavement base sample in the transfer box 96 is pushed out, so that the steel slag pavement base sample falls into the collection box 20, and the tested steel slag pavement base samples are collected centrally.
