Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and more specifically, relates to a white latex freeze-thaw stability detection device. Background Art

[0002] Freeze-thaw refers to a physical effect and phenomenon in which the soil freezes and melts due to the temperature dropping below zero and rising above zero. A detection device is required when testing the freeze-thaw stability of white emulsion.

[0003] After the existing device completes the test of the white latex after freeze-thaw, the white latex needs to be taken out from the test device. During the test, the white latex needs to be placed in a box for freeze-thaw. Because the white latex is in blocks after freeze-thaw, it is not convenient to take it out of the box, which wastes time. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a white latex freeze-thaw stability detection device to solve the problem that after the existing device completes the detection of white latex after freeze-thaw, the white latex needs to be taken out from the detection device, and the white latex needs to be placed in a box for freeze-thaw during the detection. Because the white latex is in block shape after freeze-thaw, it is not convenient to take it out of the box, which wastes time.

[0005] The purpose and function of the freeze-thaw stability detection device of white latex in the utility model are achieved by the following specific technical means:

[0006] A white latex freeze-thaw stability detection device comprises a box body; an observation window is installed at the front end of the box body, a cover plate is buckled on the top of the box body, a mounting block is welded to the left and right end faces of the box body, two first electric cylinders are fixed to the top face of each mounting block, and the upper ends of the four first electric cylinders are fixed to the cover plate; four first connecting rods are welded to the bottom end face of the cover plate, and the lower ends of the four first connecting rods are welded to the support plate.

[0007] Furthermore, an auxiliary groove is opened on the box body, and an air inlet pipe and an exhaust pipe are welded to the left end face and the right end face of the box body. The air inlet pipe and the exhaust pipe are both connected to the auxiliary groove, and the air inlet pipe is connected to the external cold air supply pump.

[0008] Furthermore, a detection assembly is installed on the cover plate, and the detection assembly consists of a second connecting rod, a detection block, an electromagnet, a second electric cylinder, an elastic part, a ruler, a switch box and a connecting block. A second connecting rod is slid on the cover plate, and a detection block is welded to the lower end of the second connecting rod. An electromagnet is fixed on the bottom end surface of the cover plate, and the electromagnet is adsorbed and connected to the detection block.

[0009] Furthermore, a connecting block with a rectangular block structure is welded on the top surface of the second connecting rod, and an elastic part is connected to the bottom of the connecting block, which is made of rubber; a second electric cylinder is fixed on the top surface of the cover plate, and the protruding end of the second electric cylinder is connected to the lower end of the elastic part.

[0010] Furthermore, a ruler is fixed on the top surface of the cover plate, and the front end surface of the ruler contacts the rear end surface of the connecting block.

[0011] Furthermore, a switch box is fixed on the top surface of the cover plate, and the switch box is electrically connected to the first electric cylinder, the electromagnet and the second electric cylinder.

[0012] Furthermore, two support blocks are fixed to the bottom end surface of the box body, and a gap exists between the box body and the workbench under the support of the two support blocks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this application, the extension of four first electric cylinders is controlled by the setting of the first connecting rod and the supporting plate. The four first electric cylinders drive the cover plate to move upward. When the cover plate moves upward, the first connecting rod and the supporting plate can be driven upward at the same time. At this time, the supporting plate drives the frozen-thawed latex to move upward, and the frozen-thawed latex can be easily unloaded.

[0015] In the present application, through the setting of the detection component, the power supply of the electromagnet is cut off. At this time, the second connecting rod and the detection block move downward under the action of gravity until the bottom end surface of the detection block contacts the frozen and thawed latex. At this time, the scale of the connecting block on the ruler is observed to control the contraction of the second electric cylinder. At this time, the second electric cylinder drives the elastic part, the second connecting rod and the detection block to move downward until the contraction of the second electric cylinder is completed. At this time, the degree of descent of the detection block can be observed through the observation window, and the detection is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1:

[0028] As attached Figure 1 To the attached Figure 6 As shown:

[0029] The utility model provides a white latex freeze-thaw stability detection device, comprising a box body 1; an observation window is installed at the front end of the box body 1, a cover plate 101 is buckled on the top of the box body 1, and a mounting block 2 is welded to the left and right end faces of the box body 1, and two first electric cylinders 201 are fixed to the top face of each mounting block 2, and the upper ends of the four first electric cylinders 201 are fixed to the cover plate 101; four first connecting rods 202 are welded to the bottom end face of the cover plate 101, and the lower ends of the four first connecting rods 202 are welded to the supporting plate 203. When unloading, the four first electric cylinders 201 are controlled to extend, and the four first electric cylinders 201 drive the cover plate 101 to move upward. When the cover plate 101 moves upward, it can simultaneously drive the first connecting rods 202 and the supporting plate 203 to move upward. At this time, the supporting plate 203 drives the frozen and thawed latex to move upward, and the frozen and thawed latex can be conveniently unloaded at this time.

[0030] Among them, an auxiliary groove 102 is opened on the box body 1, and an air inlet pipe 103 and an exhaust pipe 104 are welded on the left end face and the right end face of the box body 1. The air inlet pipe 103 and the exhaust pipe 104 are both connected to the auxiliary groove 102. The air inlet pipe 103 is connected to the external cold air supply pump. When the latex is frozen by cold air, the cold air supply pump transports the cold air to the auxiliary groove 102 through the air inlet pipe 103, and then discharges it through the exhaust pipe 104. When the cold air enters the auxiliary groove 102, the freezing and thawing of the latex can be gradually realized.

[0031] Among them, a detection component 3 is installed on the cover 101, and the detection component 3 consists of a second connecting rod 301, a detection block 302, an electromagnet 303, a second electric cylinder 304, an elastic member 305, a scale 306, a switch box 307 and a connecting block 308. A second connecting rod 301 is slid on the cover 101, and a detection block 302 is welded to the lower end of the second connecting rod 301. An electromagnet 303 is fixed to the bottom end surface of the cover 101, and the electromagnet 303 is adsorbed and connected to the detection block 302.

[0032] Among them, a rectangular block-shaped connecting block 308 is welded to the top surface of the second connecting rod 301, and an elastic part 305 is connected to the bottom of the connecting block 308, and the elastic part 305 is made of rubber; a second electric cylinder 304 is fixed to the top surface of the cover plate 101, and the protruding end of the second electric cylinder 304 is connected to the lower end of the elastic part 305.

[0033] Among them, a ruler 306 is fixed on the top surface of the cover 101, and the front end surface of the ruler 306 contacts the rear end surface of the connecting block 308. During detection, the power supply of the electromagnet 303 is cut off. At this time, the second connecting rod 301 and the detection block 302 move downward under the action of gravity until the bottom end surface of the detection block 302 contacts the frozen and thawed latex. At this time, observe the scale of the connecting block 308 on the ruler 306 and control the contraction of the second electric cylinder 304. At this time, the second electric cylinder 304 drives the elastic part 305, the second connecting rod 301 and the detection block 302 to move downward until the second electric cylinder 304 completes the contraction. At this time, the degree of descent of the detection block 302 can be observed through the observation window.

[0034] Among them, a switch box 307 is fixed on the top surface of the cover 101. The switch box 307 is electrically connected to the first electric cylinder 201, the electromagnet 303 and the second electric cylinder 304. During use, pressing the switch on the switch box 307 can control the operation and stop of the first electric cylinder 201, the electromagnet 303 and the second electric cylinder 304.

[0035] Example 2:

[0036] Based on the first embodiment, two support blocks 105 are fixed to the bottom end surface of the box 1. Under the support of the two support blocks 105, there is a gap between the box 1 and the workbench. When transporting, it is convenient to insert the hand into the bottom of the box 1, which facilitates the transportation of the device.

[0037] Working principle: During detection, the power supply of the electromagnet 303 is cut off. At this time, the second connecting rod 301 and the detection block 302 move downward under the action of gravity until the bottom end surface of the detection block 302 contacts the frozen-thawed latex. At this time, observe the scale of the connecting block 308 on the ruler 306 and control the second electric cylinder 304 to contract. At this time, the second electric cylinder 304 drives the elastic part 305, the second connecting rod 301 and the detection block 302 to move downward until the second electric cylinder 304 is completely contracted. At this time, the degree of descent of the detection block 302 can be observed through the observation window; during unloading, the four first electric cylinders 201 are controlled to extend, and the four first electric cylinders 201 drive the cover plate 101 to move upward. When the cover plate 101 moves upward, it can simultaneously drive the first connecting rod 202 and the supporting plate 203 to move upward. At this time, the supporting plate 203 drives the frozen-thawed latex to move upward, and the frozen-thawed latex can be conveniently unloaded.
