Description

Technical Field

[0001] The present invention relates to the technical field of mortar detection equipment, and in particular to a device and method for detecting the thermal insulation performance of thermal insulation mortar. Background Art

[0002] Thermal insulation mortar is a premixed dry mortar made by mixing various lightweight materials as aggregates, cement as binder, and some modified additives. It is mainly used for thermal insulation of building exterior walls. It has the advantages of convenient construction and good durability. When conducting thermal insulation performance tests, the thermal insulation mortar is first placed in a model frame to shape it. After the thermal insulation mortar is shaped in the model frame, it can be covered with a heat-conducting iron plate. Heat is transferred to the thermal insulation mortar block through the heat-conducting iron plate. By monitoring the temperature transfer efficiency, the thermal insulation performance test is achieved. In order to ensure recyclability, the testing equipment is mostly made of metal materials. In order to improve the testing efficiency, the temperature of the heating end of the equipment will exceed one hundred degrees Celsius.

[0003] Among them, after the mortar solidifies into a block, the side walls of the mortar block will stick to the side walls of the mold. Currently, most molds are made of metal. If heat conduction testing is performed without demolding, the metal mold will absorb the heat inside the mortar block. The conduction speed of metal is higher than the transmission efficiency of the mortar block. As a result, the heat absorbed by the metal mold will affect the detection instrument at the other end. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a device for testing the thermal insulation performance of thermal insulation mortar, comprising a base, a shell fixedly connected to the top of the base, a heating instrument fixedly connected to the inner wall of the shell, and a heat sink fixedly connected to the other end of the heating instrument; The heating mechanism includes a fixed column, a heating folding plate for receiving heat from the heat dissipation plate, an annular fixed plate, and a receiving assembly for the demoulding mortar block; The inner wall of the shell is fixedly connected to the side wall of the fixing column, the other end of the fixing column is fixedly connected to the outer wall of the heated folding plate, and the bottom of the heated folding plate is fixedly connected to the top of the annular fixing plate.

[0005] Preferably, the accommodating assembly includes a fixed plate fixedly connected to the inner wall of the annular fixed plate, a plurality of through-hole slots are opened on the top of the fixed plate, and sliding square columns are slidably connected to the inner walls of the plurality of through-hole slots. Before use, the base is installed in the required position, and ensure that the electric telescopic rod is in the highest position. At this time, the fixed plate and the sliding square column are at the same level to form the mold bottom plate, and the heat dissipation plate, the heated folding plate and a plurality of rotating plates at both ends form the mold side walls. After the mortar is poured into the top of the fixed plate, the mortar will diffuse outward from the inside of the mold, and eventually fill the mold side walls and solidify.

[0006] Preferably, the accommodating component also includes an electric telescopic rod fixedly connected to the top of the base, the end of the electric telescopic rod away from the base is fixedly connected to a mounting plate, and a temperature sensor is fixedly connected to a side of the heated folding plate close to the fixed column. Utilizing the bending characteristics of the above-mentioned heated folding plate, when the mortar is poured into the mold, the mortar is affected by the bent outer wall of the heated folding plate. After the mortar solidifies, the side of the mortar block close to the heated folding plate will present a trapezoidal state. After the equipment completes demoulding, the heat dissipation plate heats the plane of the mortar block. As the temperature of the mortar block rises, the temperature received by the heating instrument is transmitted to the temperature sensor through the heated folding plate. Through the application of the above-mentioned components, the thermal insulation data of mortar blocks of different thicknesses can be detected to improve the detection efficiency of the equipment.

[0007] Preferably, the accommodating component also includes a plurality of mounting grooves provided on the top of the mounting plate, and telescopic rods are fixedly connected to the inner walls of the plurality of mounting grooves, and the other ends of the plurality of telescopic rods are fixedly connected to the bottom of the sliding square column. In view of the problem that the mortar uses lightweight materials as aggregates and cement as binder, and its own bearing capacity is too low after solidification, the closer the telescopic rods are to the heating instrument, the longer the length that can be pulled. When the mounting plate moves downward, the telescopic rods will be extended, and the row of telescopic rods closest to the fixed column will be extended to the longest state. At this time, the telescopic rods will drive the sliding square column to slide downward synchronously, and as the mounting plate continues to descend, the plurality of sliding square columns will gradually descend, presenting a Figure 6 The mortar block is in the middle G state, and as the sliding square columns gradually move downward, multiple sliding square columns will be away from the bottom of the mortar block; through the application of the above components, the mortar block can be slowly demoulded multiple times to avoid damage to the mortar block due to excessive demoulding resistance, thereby affecting the detection effect.

[0008] Preferably, the closer the telescopic rod is to the heating instrument, the longer the length it can be pulled up is, and the pulling lengths of two laterally adjacent telescopic rods are equal. Mold assemblies are provided on both sides of the annular fixing plate.

[0009] Preferably, the mold assembly includes several rotating plates rotatably connected to both sides of the annular fixed plate, and the several rotating plates are provided with grooves on the sides away from the heating instrument, and the several rotating plates are fixedly connected with protrusions on the sides close to the heating instrument. After the condensation is completed, the power of the electric telescopic rod and the heating instrument is turned on. At this time, the electric telescopic rod generates a contraction force, and the contracted electric telescopic rod drives the several telescopic rods to move downward through the mounting plate, so that the through-hole slide groove forms a hollow state. As the mounting plate descends, the mounting plate drives the pulling line and the mounting block to move synchronously through the moving long plate, and forces the rotating plate to rotate downward with the torsion spring as the center, so that the several rotating plates are opened to both sides. At this time, there is still adhesion between the mortar block and the heat dissipation plate and the heated folding plate. The heat generated by the heating instrument is transmitted to the mortar block through the heat dissipation plate, and is transmitted from the mortar block to the heated folding plate and the temperature sensor. Through the application of the above-mentioned components, the rotating plate and the sliding square column are kept away from the mortar block, thereby preventing the heat generated by the heating instrument from being transmitted to the heated folding plate through the rotating plate, affecting the detection accuracy of the temperature sensor at the side wall of the heated folding plate.

[0010] Preferably, the mold assembly further comprises a mounting block fixedly connected to an outer wall of the rotating plate, a rotating block is rotatably connected to the inner wall of the mounting block, and a pulling line is fixedly connected to the outer wall of the rotating block.

[0011] Preferably, the mold assembly also includes a movable long plate fixedly connected to the side wall of the mounting plate, the end of the pulling line away from the rotating block is fixedly connected to the top of the movable long plate, and a sealing assembly is fixedly connected to the side wall of the rotating plate.

[0012] Preferably, the sealing assembly includes two grooves provided at both ends of the heated folding plate, two protrusions fixedly connected to the side wall of the rotating plate, three grooves provided at both ends of the heat dissipation plate, three protrusions fixedly connected to the side wall of the rotating plate, a torsion spring fixedly connected to the inner wall of the rotating plate, and the other end of the torsion spring fixedly connected to the outer wall of the annular fixed plate. The pulling wire is used to drive the rotating plate to rotate downward, and a pulling wire is provided inside the device, wherein the closer the pulling wire is to one end of the heating instrument, the longer the length is. When the installation plate drives the pulling wire to move down, the pulling wire will appear as follows due to the different lengths of the pulling wire. Figure 9 The T-shaped state allows the rotating plate to slowly and repeatedly move away from the side wall of the mortar block during demoulding, ensuring that the area of ​​the rotating plate separated outward in a single time is smaller than the contact area of ​​the heated folding plate. The application of the above components ensures the stability of the demoulding equipment and avoids excessive contact area during a single demoulding, which would cause excessive damage to the side wall of the mortar block and affect the thermal conductivity of the mortar.

[0013] A method for detecting thermal insulation performance of thermal insulation mortar comprises the following steps: S1: Install the equipment: Before use, install the base in the desired position and ensure that the electric telescopic rod is in the highest position. At this time, the fixed plate and the sliding square column are at the same level to form the mold bottom plate; S2: Place mortar: After the mortar has solidified, the electric telescopic rod and the heating device are powered on. The electric telescopic rod generates a contraction force, and the contracted electric telescopic rod drives several telescopic rods to move downward through the mounting plate.

[0014] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that the mortar solidifies into blocks before being tested. A heating mechanism and a containing assembly are provided inside the device. Before use, the base is installed in the desired position and the electric telescopic rod is ensured to be in the highest position. At this time, the fixed plate and the sliding square column are at the same level to form the bottom plate of the mold, while the heat dissipation plate, the heated folding plate and several rotating plates at both ends form the side walls of the mold. After the mortar is poured into the top of the fixed plate, the mortar will diffuse outward from the inside of the mold and eventually fill the side walls of the mold and solidify. After solidification is completed, the power supply of the electric telescopic rod and the heating instrument is turned on. At this time, the electric telescopic rod generates a contraction force, and the contracted electric telescopic rod drives several The telescopic rod moves downward, causing the through-hole slide groove to form a hollow state. As the mounting plate descends, the mounting plate drives the pulling line and the mounting block to move synchronously by moving the long plate, and forces the rotating plate 1 to rotate downward with the torsion spring as the center, so that several rotating plates 1 are opened to both sides. At this time, there is still adhesion between the mortar block and the heat sink and the heated folding plate. The heat generated by the heating instrument is transferred to the mortar block through the heat sink, and from the mortar block to the heated folding plate and the temperature sensor. Through the application of the above components, the rotating plate 1 and the sliding square column are kept away from the mortar block, thereby preventing the heat generated by the heating instrument from being transferred to the heated folding plate through the rotating plate 1, affecting the detection accuracy of the temperature sensor at the side wall of the heated folding plate.

[0015] (2) The present invention addresses the problem that the mortar, which uses lightweight materials as aggregates and cement as binder, has too low a bearing capacity after solidification. The closer the telescopic rod is to the heating instrument, the longer it can be pulled. When the mounting plate moves downward, the telescopic rod will extend. The row of telescopic rods closest to the fixed column will extend to the longest state. At this time, the telescopic rod will drive the sliding square column to slide downward synchronously. As the mounting plate continues to descend, several sliding square columns will gradually descend, presenting a Figure 6 The mortar block is in the middle G state, and as the sliding square columns gradually move downward, multiple sliding square columns will be away from the bottom of the mortar block; through the application of the above components, the mortar block can be slowly demoulded multiple times to avoid damage to the mortar block due to excessive demoulding resistance, thereby affecting the detection effect.

[0016] (3) The present invention utilizes the bending characteristics of the above-mentioned heated folding plate. When the mortar is poured into the mold, the mortar is affected by the outer wall of the bent heated folding plate. After the mortar solidifies, the side of the mortar block close to the heated folding plate will present a trapezoidal state. After the equipment completes demoulding, the heat dissipation plate heats the plane of the mortar block. As the temperature of the mortar block rises, the temperature received by the heating instrument is transmitted to the temperature sensor through the heated folding plate. Through the application of the above-mentioned components, the thermal insulation data of mortar blocks of different thicknesses can be detected to improve the detection efficiency of the equipment.

[0017] (4) The present invention utilizes the characteristic that the pulling wire drives the rotating plate to rotate downward. A pulling wire is provided inside the device. The closer the pulling wire is to the heating instrument, the longer the length is. When the installation plate drives the pulling wire to move downward, the pulling wire will present the following characteristics due to the different lengths of the pulling wire. Figure 9 The T-shaped state allows the rotating plate to slowly and repeatedly move away from the side wall of the mortar block during demoulding, ensuring that the area of ​​the rotating plate separated outward in a single time is smaller than the contact area of ​​the heated folding plate. The application of the above components ensures the stability of the demoulding equipment and avoids excessive contact area during a single demoulding, which would cause excessive damage to the side wall of the mortar block and affect the thermal conductivity of the mortar.

Before use, the base 1 is installed in the desired position, and it is ensured that the electric telescopic rod 33 is in the highest position. At this time, the fixed plate 31 and the sliding square column 32 are at the same level to form the bottom plate of the mold, and the heat dissipation plate 13, the heated folding plate 22 and a plurality of rotating plates 41 at both ends form the side walls of the mold. After the mortar is poured into the top of the fixed plate 31, the mortar will diffuse outward from the inside of the mold, and eventually fill the side walls of the mold and solidify.

[0024] The accommodating component 3 also includes an electric telescopic rod 33 fixedly connected to the top of the base 1, and the end of the electric telescopic rod 33 away from the base 1 is fixedly connected to the mounting plate 34, and the side of the heated folding plate 22 close to the fixed column 21 is fixedly connected to a temperature sensor. By utilizing the bending characteristics of the above-mentioned heated folding plate 22, when the mortar is poured into the mold, the mortar is affected by the bent outer wall of the heated folding plate 22. After the mortar solidifies, the side of the mortar block close to the heated folding plate 22 will present a trapezoidal state. After the equipment completes demoulding, the heat dissipation plate 13 heats the plane of the mortar block. As the temperature of the mortar block rises, the temperature received by the heating instrument 12 is transmitted to the temperature sensor through the heated folding plate 22. Through the application of the above-mentioned components, the thermal insulation data of mortar blocks of different thicknesses can be detected to improve the detection efficiency of the equipment.

[0025] The accommodating component 3 also includes a plurality of mounting grooves 35 provided on the top of the mounting plate 34, and a plurality of telescopic rods 36 are fixedly connected to the inner walls of the plurality of mounting grooves 35, and the other ends of the plurality of telescopic rods 36 are fixedly connected to the bottom of the sliding square column 32. In view of the problem that the mortar uses lightweight materials as aggregates and cement as binder, and its own bearing capacity is too low after solidification, the closer the telescopic rods 36 are to the heating instrument 12, the longer the length that can be pulled is. When the mounting plate 34 moves downward, the telescopic rods 36 will be extended, and the row of telescopic rods 36 closest to the fixed column 21 will be extended to the longest state. At this time, the telescopic rods 36 will drive the sliding square column 32 to slide downward synchronously, and as the mounting plate 34 continues to descend, the plurality of sliding square columns 32 will gradually descend, presenting a Figure 6 The state of middle G, and as the sliding square pillars 32 gradually move downward, the multiple sliding square pillars 32 will be away from the bottom of the mortar block; through the application of the above components, the mortar block can be slowly demoulded multiple times to avoid the mortar block being damaged due to excessive demoulding resistance, thereby affecting the detection effect.

[0026] The closer the telescopic rod 36 is to the heating instrument 12 , the longer the length it can be pulled. The pulling lengths of two laterally adjacent telescopic rods 36 are equal. Mold assemblies 4 are provided on both sides of the annular fixing plate 23 .

At this time, there is still adhesion between the mortar block and the heat dissipation plate 13 and the heated folding plate 22. The heat generated by the heating instrument 12 is transmitted to the mortar block through the heat dissipation plate 13, and is transmitted from the mortar block to the heated folding plate 22 and the temperature sensor. Through the application of the above components, the rotating plate 41 and the sliding square column 32 are kept away from the mortar block, thereby preventing the heat generated by the heating instrument 12 from being transmitted to the heated folding plate 22 through the rotating plate 41, affecting the detection accuracy of the temperature sensor at the side wall of the heated folding plate 22.

When the mounting plate 34 drives the pulling wire 46 to move downward, due to the different lengths of the pulling wire 46, the pulling wire 46 will appear as follows Figure 9The T-shaped state allows the rotating plate 1 41 to slowly and repeatedly move away from the side wall of the mortar block during demoulding, ensuring that the area of ​​the rotating plate 1 41 separated outward in a single time is smaller than the contact area of ​​the heated folding plate 22. The application of the above components ensures the stability of the demoulding equipment. This prevents excessive contact area during a single demoulding, which would cause excessive damage to the side wall of the mortar block and affect the thermal conductivity of the mortar.

[0031] The detection method of the thermal insulation performance detection device of the thermal insulation mortar comprises the following steps: S1: Install the equipment: Before use, install the base 1 in the desired position and ensure that the electric telescopic rod 33 is in the highest position.

After the mortar is poured into the top of the fixed plate 31, the mortar will diffuse outward from the inside of the mold and eventually fill the mold side walls and solidify. After solidification is completed, the power supply of the electric telescopic rod 33 and the heating device 12 is turned on. At this time, the electric telescopic rod 33 generates a contraction force. The contracted electric telescopic rod 33 drives the plurality of telescopic rods 36 to move downward through the mounting plate 34, so that the through-hole slide groove 37 forms a hollow shape. state, and as the mounting plate 34 descends, the mounting plate 34 drives the pulling wire 46 and the mounting block 44 to move synchronously by moving the long plate 47, and forces the rotating plate 41 to rotate downward with the torsion spring 55 as the center, so that several rotating plates 41 are opened to both sides. At this time, there is still adhesion between the mortar block and the heat sink 13 and the heated folding plate 22. The heat generated by the heating instrument 12 is transferred to the mortar block through the heat sink 13, and is transferred from the mortar block to the heated folding plate 22 and the temperature sensor. Through the application of the above components, the rotating plate 41 and the sliding square column 32 are kept away from the mortar block, thereby preventing the heat generated by the heating instrument 12 from being transferred to the heated folding plate 22 through the rotating plate 41, affecting the detection accuracy of the temperature sensor at the side wall of the heated folding plate 22.

[0033] In order to solve the problem that the mortar uses lightweight materials as aggregates and cement as binder, and its own bearing capacity is too low after solidification, the closer the telescopic rods 36 are to the heating instrument 12, the longer they can be pulled. When the mounting plate 34 moves downward, the telescopic rods 36 will extend, and the row of telescopic rods 36 closest to the fixed column 21 will extend to the longest state.

[0034] By utilizing the bending characteristics of the above-mentioned heated folding plate 22, when the mortar is poured into the mold, the mortar is affected by the bent outer wall of the heated folding plate 22. After the mortar solidifies, the side of the mortar block close to the heated folding plate 22 will be in a trapezoidal state. After the equipment completes demoulding, the heat dissipation plate 13 heats the plane of the mortar block. As the temperature of the mortar block rises, the temperature received by the heating instrument 12 is transmitted to the temperature sensor through the heated folding plate 22. Through the application of the above-mentioned components, the thermal insulation data of mortar blocks of different thicknesses can be detected to improve the detection efficiency of the equipment.

[0035] The pulling wire 46 is used to drive the rotating plate 41 to rotate downward. A pulling wire 46 is provided inside the device. The closer the pulling wire 46 is to the heating instrument 12, the longer the length is. When the mounting plate 34 drives the pulling wire 46 to move downward, the pulling wire 46 will be in the following shape due to the different lengths of the pulling wire 46.
