Description

Technical Field

[0001] The invention relates to the technical field of rail transit adhesive viscosity testing, and in particular to an adhesive viscosity testing device for rail transit. Background Art

[0002] Rail transit adhesive is a kind of adhesive specially designed for rail transit system. It is usually used to fix rails, insulating joints, bracket seats and other components to ensure the stability and safety of the rail system. This adhesive needs to have anti-vibration, wear resistance, anti-aging and other characteristics to meet the needs of rail transit environment.

[0003] In the process of viscosity testing of adhesives for rail transit, a viscosity testing device is one of the indispensable devices. Most of the viscosity testing devices on the market are unable to classify and grade the viscosity of adhesives, and are unable to detect their anti-vibration performance in a moving state. Therefore, a viscosity testing device for adhesives for rail transit is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an adhesive viscosity testing device for rail transit.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An adhesive viscosity testing device for rail transit comprises a detection unit and an adjustment unit. The outer ring of the detection unit is sleeved with the adjustment unit. The detection unit comprises a detection tube and an insertion frame vertically inserted into the inner cavity of the detection tube. Two groups of the insertion frames are connected in series via a connecting belt. A positioning mechanism is vertically arranged on the upper end surface of the insertion frame. Testing mechanisms are vertically arranged on both sides of the inner end surfaces of the two groups of the detection tubes. A grading mechanism is vertically installed on the lower end surface of the testing mechanism.

[0006] Preferably, the detection cylinder includes a cylinder body and an insertion shaft opened on both sides of the inner end surface of the cylinder body, the inner cavity wall of the insertion shaft is vertically arranged with inner recessed grooves, a positioning vertical groove is set on one side of the top of the cylinder body, and an insertion cavity is vertically opened on the outer side of the positioning vertical groove.

[0007] Preferably, the insertion rack vertically penetrates into the inner cavity of the insertion cavity from bottom to top, and the outer end wall of the insertion rack is in contact with the inner cavity wall of the insertion cavity. When the adhesive can flow through the discharge hole into the second detection unit under the drive of gravity, the grading mechanism set up can share the adhesive under test. When the same adhesive under test is adsorbed and remains in the test mechanism and the grading mechanism, although the mass is equal at this time, the surface area of ​​the adsorbed residue is increased, so that the adhesive under test can be gravity-dropped to the test mechanism set below the grading mechanism, so that the outer end wall of its elastic outer ring gives gravity drive to the inner recessed groove downward, and the staff disassembles the bottom cylinder. At this time, the viscosity of the adhesive is preset to a medium level.

[0008] Preferably, the positioning mechanism comprises a positioning cylinder and an adapting groove opened on the top of the positioning cylinder, the two groups of positioning cylinders are connected in series through a lifting cylinder, a fixing cylinder is arranged on the top of the adapting groove, and an adapting protrusion is arranged on the bottom of the fixing cylinder, and positioning ear blocks are horizontally arranged on both sides of the outer end wall edge of the adapting protrusion, the positioning cylinder and the fixing cylinder are vertically inserted into the inner cavity of the positioning vertical groove, and the lower end surface of the positioning ear block is flattened at the connection between the cylinder body and the positioning vertical groove. When the adhesive is being tested, the staff inserts the insertion frame vertically into the inner cavity of the insertion cavity from bottom to top, so that the bottom of the insertion frame is just above the bottom end surface of the cylinder body. At this time, the positioning mechanism is driven by the insertion frame to move vertically with the inner cavity wall of the positioning vertical groove as the path, and can change the degree of fit between the adapting groove and the adapting protrusion based on the viscosity of the adhesive being tested. When the viscosity of the adhesive is preset to a low level, the adapting groove and the adapting protrusion are adsorbed and contacted with each other, thereby strengthening the series connection strength between multiple groups of detection cylinders and avoiding the situation where multiple groups of detection cylinders are detached.

[0009] Preferably, the testing mechanism includes a measuring disk and an elastic outer ring annularly sleeved on the outer end surface of the measuring disk, a material receiving trough is annularly arranged on the upper end surface of the measuring disk, a material discharge hole is opened around the bottom of the inner cavity wall of the material receiving trough, a reinforcing cylinder is vertically arranged on the top of the measuring disk, and a receiving ball is arranged on the top of the reinforcing cylinder. When the adhesive can flow through the material discharge hole and enter the third detection unit under the drive of gravity, the tested adhesive can pass through the set testing mechanism and multiple groups of grading mechanisms and then enter the inner cavity of the bottom reinforcing cylinder for temporary storage. At this time, the staff will not dismantle any structure, and the viscosity of the adhesive is preset to a low level.

[0010] Preferably, a grading mechanism is interspersed on the lower end surface of the measuring plate, and the grading mechanism includes a receiving plate and a downward vertical tube installed at the bottom of the receiving plate. The outer ring bottom of the downward vertical tube is provided with a discharge cavity in an annular array, so that each set of testing mechanisms and grading mechanisms are combined to form a single set of adhesive viscosity detection units. When the adhesive enters the device and passes through the detection unit formed by each set of testing mechanisms and grading mechanisms, it will remain or be adsorbed on the surface of the structure it passes through due to the viscosity of the adhesive itself. When the adhesive cannot enter the second detection unit due to gravity, When the measuring plate is pressed downward, the grading mechanism will not exert excessive weight pressure on the measuring plate, and the testing mechanism as a whole will bear the entire weight of the tested adhesive. The lower end surface of the elastic outer ring of the outer end wall will cling to the inner cavity wall of the inner concave groove. The measuring plate will fall vertically downward at this time, but the elastic outer ring will limit the downward trend of the measuring plate. The staff can disassemble the grading mechanism that is not in contact with the multiple sets of cylinders and adhesives, and the staff can directly observe the viscosity of the adhesive in the testing state from the bottom of the device upward. At this time, the viscosity of the adhesive is preset to a high grade. Workers can disassemble the device and directly observe the viscosity of the adhesive to set it to a high level in advance. This design helps simplify the process of adhesive viscosity testing and enables workers to easily perform inspections and evaluations.

[0011] Preferably, the measuring disk and the elastic outer ring are inserted into the inner cavity of the inner recessed groove, and the outer end wall of the elastic outer ring is fitted with the inner end wall of the inner recessed groove. The adhesive to be tested is poured from top to bottom into the inner cavity of the insertion shaft, and when the adhesive contacts the receiving ball, it will flow downward along the outer wall of the receiving ball until the adhesive is poured into the inner cavity of the material holding trough all around, and the adhesive will penetrate downward through the discharge hole into the grading mechanism below, and the adhesive entering the inner cavity of the grading mechanism will flow downward along the inner cavity wall of the downward descending vertical pipe, and the adhesive contacting the bottom of the downward descending vertical pipe will penetrate outward through the inner cavity of the discharge cavity and be discharged into the inner cavity of the material holding trough connected to its bottom. At this time, the adhesive also needs to pass through the combined structure composed of two sets of testing mechanisms and the grading mechanism, and driven by gravity, the adhesive will move downward into the inner cavity of the bottom reinforcement cylinder for temporary storage.

[0012] Preferably, the adjustment unit comprises an adjustment frame and a connecting piece connected in series between a plurality of adjustment frames, a positioning horizontal axis is vertically arranged on the outer end surface of the middle adjustment frame, and push slide bars are vertically arranged on the outer end surfaces of the adjustment frames at both ends, the other end of the positioning horizontal axis is connected to the outer end surface of the clamping frame, the push slide bar passes through the outer end wall of the clamping frame, a first clamping ring is fitted on the inner cavity wall of the clamping frame, the other end of the push slide bar is connected to the outer end wall of the first clamping ring, and a second clamping ring is arranged on the other end of the first clamping ring; Preferably, the inner end walls of the first clamping ring and the second clamping ring are clamped on the outer end wall of the cylinder, so that the detection unit and the adjustment unit become a whole. When it is necessary to detect the peeling condition of the adhesive being tested in the device in a moving state, the staff only needs to split the cylinder in a spliced ​​state into four parts with its center as the fulcrum, and continuously clamp two of them in the inner end wall of the first clamping ring. The staff adjusts the adjustment frames on both sides with the middle adjustment frame as the fulcrum, so that the adjustment frame can drive the push slide bar to perform lateral telescopic swing. While the push slide bar is adjusted, the connected first clamping ring performs active clamping adjustment to the cylinder in a clamped state, so that the adhesive being tested shakes irregularly laterally in the detection cylinder, thereby simulating the viscosity level of the adhesive in a moving state. This method can help staff quickly understand the characteristics of the adhesive in a moving state, which is helpful for detecting and evaluating its performance.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the adhesive enters the device and passes through the detection unit formed by each set of testing mechanisms and grading mechanisms, it will remain or be adsorbed on the surface of the structure it passes through due to the viscosity of the adhesive itself. When the adhesive cannot enter the second detection unit due to gravity, the staff can disassemble the multiple sets of cylinders and grading mechanisms that the adhesive does not contact, and the staff can directly observe the viscosity of the adhesive in the detection state from the bottom of the device upward. At this time, the viscosity of the adhesive is preset to a high level; Workers can disassemble the device and directly observe the viscosity of the adhesive to set it to a high level in advance. This design helps simplify the process of adhesive viscosity testing and enables workers to easily perform inspections and evaluations.

[0014] When the adhesive is able to flow through the discharge hole into the second testing unit driven by gravity, the grading mechanism set up can distribute the adhesive under test. When the same amount of adhesive under test is adsorbed and remains in the testing mechanism and the grading mechanism, although the mass is equal at this time, the surface area of ​​the adsorbed residue is increased, so that the adhesive under test can be gravity-dropped to the testing mechanism set up below the grading mechanism, so that the outer end wall of its elastic outer ring gives gravity-driven downward to the inner recessed groove. The staff disassembles the bottom cylinder. At this time, the viscosity of the adhesive is preset to a medium level.

[0015] When the adhesive is able to flow through the discharge hole into the third testing unit driven by gravity, the tested adhesive can pass through the set testing mechanism and multiple groups of grading mechanisms and then enter the inner cavity of the bottom reinforcement cylinder for temporary storage. At this time, the staff will not dismantle any structure. At this time, the viscosity of the adhesive is preset to a low level.

[0016] When the adhesive is being tested, the staff inserts the insertion frame vertically into the inner cavity of the insertion cavity from bottom to top, so that the top of the bottom of the insertion frame fits against the bottom end surface of the cylinder. At this time, the positioning mechanism, driven by the insertion frame, moves vertically along the inner cavity wall of the positioning vertical groove, and can change the degree of fit between the adapter groove and the adapter protrusion based on the viscosity of the adhesive being tested. When the viscosity of the adhesive is preset to a low level, the adapter groove and the adapter protrusion are adsorbed and contacted with each other, thereby enhancing the series strength between multiple groups of test cylinders and avoiding the situation where multiple groups of test cylinders are detached.

[0017] It is possible to test the peeling condition of the adhesive being tested in the device in a moving state and simulate the viscosity level of the adhesive in a moving state. This method can help staff quickly understand the characteristics of the adhesive in a moving state and help to detect and evaluate its performance. BRIEF DESCRIPTION OF THE DRAWINGS

The adhesive entering the inner cavity of the grading mechanism 16 will flow downward along the inner cavity wall of the downward vertical pipe 162, and the adhesive that contacts the bottom of the downward vertical pipe 162 will penetrate outward through the inner cavity of the discharge cavity 163 and be discharged into the inner cavity of the material tank 153 connected to the bottom thereof. At this time, the adhesive also needs to pass through the combined structure composed of the two sets of testing mechanisms 15 and the grading mechanism 16, and the adhesive will enter the inner cavity of the bottom reinforcement cylinder 155 for temporary storage under the force of gravity. Each set of test mechanism 15 and grading mechanism 16 is combined to form a single set of adhesive viscosity detection unit. When the adhesive enters the device and passes through the detection unit formed by each set of test mechanism 15 and grading mechanism 16, it will remain or be adsorbed on the surface of the structure it passes through due to the viscosity of the adhesive itself. When the adhesive cannot enter the second detection unit driven by gravity, the measuring disc 151 will not give excessive weight pressure to the grading mechanism 16 downward, and at this time, the test mechanism 15 as a whole bears the entire weight of the tested adhesive, and the lower end surface of the elastic outer ring 152 of its outer end wall will cling to the inner cavity wall of the inner concave groove 113. The measuring disc 151 falls vertically downward at this time, but the elastic outer ring 152 set will limit the falling trend of the measuring disc 151, and the staff can disassemble the multiple sets of cylinders 111 and the grading mechanism 16 that are not in contact with the adhesive, and the staff can directly observe the viscosity of the adhesive in the detection state from the bottom of the device upward, and the viscosity of the adhesive is preset to a high level at this time; Workers can disassemble the device and directly observe the viscosity of the adhesive to set it to a high level in advance. This design helps simplify the process of adhesive viscosity testing, allowing workers to easily perform inspections and evaluations; When the adhesive can flow through the discharge hole 154 into the second detection unit under the driving force of gravity, the grading mechanism 16 can distribute the adhesive to be tested. When the adhesive to be tested and measured with the same amount is adsorbed and remains in the test mechanism 15 and the grading mechanism 16, although the mass is equal at this time, the surface area of ​​the adsorbed residue is increased, so that the adhesive to be tested can be gravity-dropped to the test mechanism 15 set below the grading mechanism 16, so that the outer end wall of the elastic outer ring 152 is gravity-driven downward to the inner concave groove 113, and the staff disassembles the bottom cylinder 111. At this time, the viscosity of the adhesive is preset to a medium level; By analogy, when the adhesive can flow through the discharge hole 154 into the third detection unit driven by gravity, the adhesive under test can pass through the set test mechanism 15 and the multiple groups of grading mechanisms 16 and then enter the inner cavity of the bottom reinforcement cylinder 155 for temporary storage. At this time, the staff will not remove any structure, and the viscosity of the adhesive is preset to a low level. When the adhesive is being tested, the staff inserts the insertion rack 12 vertically into the inner cavity of the insertion cavity 115 from bottom to top, so that the top of the bottom of the insertion rack 12 is in contact with the bottom end surface of the cylinder 111. At this time, the positioning mechanism 14 is driven by the insertion rack 12 to move vertically along the inner cavity wall of the positioning vertical groove 114, and can change the degree of contact between the adapting groove 142 and the adapting protrusion 145 based on the viscosity of the adhesive being tested. When the viscosity of the adhesive is preset to a low level, the adapting groove 142 and the adapting protrusion 145 are in contact with each other, thereby strengthening the series connection strength between the multiple groups of detection cylinders 11 and preventing the multiple groups of detection cylinders 11 from being separated. When it is necessary to test the peeling condition of the adhesive under test in the device in a moving state, the staff only needs to split the cylinder 111 in a spliced ​​state into four parts with its center as the fulcrum, and continuously clamp two of them in the inner end wall of the first clamping ring 26. The staff adjusts the adjustment frames 21 on both sides with the middle adjustment frame 21 as the fulcrum, so that the adjustment frame 21 can drive the push slide bar 24 to perform lateral telescopic swing. While the push slide bar 24 is adjusted, the connected first clamping ring 26 performs active clamping adjustment to the cylinder 111 in a clamping state, so that the adhesive under test shakes irregularly laterally in the detection cylinder 11, thereby simulating the viscosity level of the adhesive in a moving state. This method can help the staff quickly understand the characteristics of the adhesive in a moving state, which is helpful for detecting and evaluating its performance.
