Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fireproof cloth detection, and particularly relates to a composite glass fiber fireproof cloth strength detection device. BACKGROUND

[0002] The core purpose of the strength test of the composite fireproof cloth is to verify the structural stability and durability of the composite fireproof cloth under high temperature and complex environment. The mechanical property tests such as tensile strength and tear strength can quantify the anti-damage ability of the material when bearing external force, so as to ensure that the material is not easy to break or deform in actual application. For example, in the field of building, the fireproof cloth needs to bear the pulling and long-term environmental stress in the installation process. The strength test data is directly related to the service life and safety factor of the material. In addition, the strength test result can also provide a basis for material optimization, such as improving wear resistance by adjusting the fiber density or coating process.

[0019] With reference to the accompanying drawings, the technical solutions in the embodiments will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments; based on the embodiments, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope.

[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments.

[0021] Since the existing cloth tensile strength side-view device, the actuator needs to simulate the stretching process through linear displacement, when testing long-size samples, the actuator must be equipped with a stroke matching the length of the cloth (for example, testing a 1-meter sample requires a stroke of ≥1 meter), resulting in a large device volume, especially for super-long fireproof cloth (such as a roll), the site occupation and mechanical complexity increase significantly, at the same time, the inertia of linear motion is large, and high-speed testing is prone to cause tension overshoot or oscillation due to acceleration limitation, affecting data accuracy, and the clamping part may cause damage to the edge of the cloth due to stress concentration, which further reduces the reliability. Therefore, in the embodiments of the present application, a composite glass fiber fireproof cloth strength detection device is provided, which aims to change the stretching mechanism, reduce the device volume, and avoid damage to the fireproof cloth by the clamp. The device mainly comprises a detection frame 10, a load plate 20 and a cloth clamp 30.

[0022] As shown in Figure 1 , Figure 2 and Figure 3 , the detection frame 10 comprises a support plate 11 and a set of guide rail frames 12, the set of guide rail frames 12 is perpendicular to the support plate 11, one side wall of the guide rail frame 12 is provided with a mounting groove, and the load plate 20 is mounted in the mounting groove of the guide rail frame 12.

[0023] It should be understood that the detection frame 10 is mainly used for mounting the load plate 20, the support plate 11 and the guide rail frame 12 are both made of stainless steel, the support plate 11 is fixed on a stable load surface or base, which can ensure the stability of the detection frame 10 as a whole, the two guide rail frames 12 are perpendicular to the support plate 11, and the space for mounting the load plate 20 is formed between the guide rail frames 12. In some embodiments, more than one load plate 20 can be mounted on the guide rail frame 12, and multiple groups of contrast detection can be performed at the same time, for example, the cloth sample 01 under different tension or different temperature.

[0024] Further, two parallelly distributed cloth clamps 30 are installed on the cylinder side of the load plate 20, and are used for mounting and fixing the cloth sample 01.

[0025] The cloth clamp 30 is configured as a roller cylinder, and the two side shaft ends of the cloth clamp 30 are provided with pressure detectors 211 for detecting the pressure of the cloth clamp 30 perpendicular to the axial direction. Thus, when the cloth sample 01 is fixed on the cloth clamp 30, and the cloth sample 01 is pulled, the pressure detected by the pressure detector 211 at the shaft end of the cloth clamp 30 is the pulling force borne by the cloth sample 01.

[0026] Further, the load plate 20 is provided with a driver 40 for driving the cloth clamp 30, and the cloth clamp 30 is provided with a positioning mechanism for fixing the cloth sample 01. Both cloth clamps 30 are used for fixing the cloth sample 01, and the side edges of the cloth sample 01 are perpendicular to the axial line of the cloth clamp 30. The driver 40 is configured to drive at least one cloth clamp 30 to rotate around its own axial line, so that the cloth sample 01 is pulled by the cloth clamp 30, and the tensile strength of the cloth sample 01 is detected by the pressure detector 211.

[0027] When the side edges of the cloth sample 01 are perpendicular to the axial line of the cloth clamp 30, it can be ensured that the cloth sample 01 is uniformly stressed in the stretched state, as shown in Figure 4 The two reel-type cloth clamps 30 respectively hold the two ends of the cloth sample 01. The driver 40 drives at least one cloth clamp 30 to rotate around its own axial line. The cloth clamp 30 winds the cloth sample 01 when rotating, so that the cloth sample 01 is continuously pulled. When it is necessary to detect whether the cloth sample 01 can bear a certain pulling force, the cloth clamp 30 can continuously pull the cloth sample 01 with the pulling force, and it is detected whether the cloth sample 01 can bear the pulling force. When it is necessary to detect the breaking force of the cloth sample 01, the cloth clamp 30 is continuously wound until the cloth sample 01 is broken, so as to detect the breaking force of the cloth sample 01, and the strength of the cloth sample 01 is judged accordingly. In the above detection process, the cloth clamp 30 pulls the cloth sample 01 in the winding manner, so that the position of the cloth sample 01 does not move, and the volume of the detection device as a whole does not change. Therefore, the volume of the detection device can be relatively compact, and the cloth clamp 30 pulls the cloth sample 01 in the winding manner, so that the connection between the cloth sample 01 and the cloth clamp 30 does not loosen, thereby ensuring the smooth progress of the detection process.

[0028] As shown in Figure 5As shown, the cloth clamp 30 comprises a roller body 31 and a positioning mechanism, the positioning mechanism comprises a positioning card strip 32, a roller groove 310 is formed on the outer wall of the roller body 31, the positioning card strip 32 is configured to be sized to the inner wall of the roller groove 310, the positioning card strip 32 is clamped in the roller groove 310 together with the cloth sample 01, and the cloth sample 01 is fixed on the roller body 31, wherein the positioning card strip 32 is parallel to the axis of the roller body 31 and perpendicular to the side edge of the cloth sample 01.

[0029] In some embodiments, the roller body 31 is made of stainless steel as a whole, the cross section of the roller groove 310 is configured as a "U" shape or a "V" shape, and a non-slip pad 311 is fixed on the inner side wall of the roller groove 310.

[0030] The length of the roller groove 310 is less than the length of the roller body 31, the length of the positioning card strip 32 is equal to the length of the roller groove 310, the length of the positioning card strip 32 is greater than the length of the cloth sample 01 in the axial direction, and the outer side sleeve of the roller body 31 is provided with a limiting ring 33 for fixing the positioning card strip 32 in the roller groove 310.

[0031] During installation, the end part of the cloth sample 01 is installed in the roller groove 310 in whole or in part, then the positioning card strip 32 is inserted into the roller groove 310, and the end part of the cloth sample 01 is fixed so that the cloth sample 01 cannot be loosened from the roller groove 310, wherein the non-slip pad 311 is made of hard rubber, the surface of the non-slip pad 311 has a tooth-shaped anti-slip pattern to increase the friction between the non-slip pad 311 and the cloth sample 01, and after the positioning card strip 32 is installed in the roller groove 310, the two limiting rings 33 on the outer side of the roller body 31 are slid from the outer side of the roller groove 310 to the two ends of the roller groove 310, so that the limiting rings 33 are arranged at the two ends of the positioning card strip 32, and the positioning card strip 32 is fixed in the roller groove 310, so that the positioning card strip 32 has a greater extrusion force on the cloth sample 01 in the roller groove 310, preventing the cloth sample 01 from loosening from the roller groove 310.

[0032] In some embodiments, when the fireproof cloth roll is subjected to sampling inspection, only whether the fireproof cloth can withstand the set tension is detected, without the need to break the fireproof cloth, at this time, in order to maintain the integrity of the fireproof cloth roll, the fireproof cloth roll is not cut, but two cloth clamps 30 are fixed to the test part randomly selected from the entire fireproof cloth roll, after fixing, two or one of the cloth clamps 30 is / are rotated, when the two cloth clamps 30 are all rotated, the rotation directions of the two cloth clamps 30 are opposite, after the detection is completed, the fireproof cloth is removed from the cloth clamps 30, and the entire process does not damage the fireproof cloth. Therefore, compared with the current linear pulling type several European clamps, the winding action naturally supports continuous testing, the double winding shafts are synchronously controlled by a servo motor, the long fireproof cloth can be tested in an infinite number of segments, and the cloth is not damaged.

[0033] AsFigure 4 and Figure 6 As shown in the figure, the driver 40 includes a motor 41, a second protective cover 42 and a transmission box 43, the transmission box 43 is arranged on the outer side wall of the load plate 20, and the transmission box 43 and the cloth clamp 30 are located on both sides of the load plate 20 respectively, the transmission box 43 is in transmission connection with both ends of the cloth clamp 30, the output end of the motor 41 is in transmission connection with the transmission box 43 through a transmission belt 421, and the second protective cover 42 covers the outside of the transmission belt 421.

[0034] In some embodiments, the motor 41 adopts a servo motor, and the rotation speed of the motor 41 is accurately controlled through a programmable controller, so as to control the tension on the cloth sample 01 during the winding of the cloth clamp 30, and the tension on the cloth sample 01 is detected by the pressure detector 211, and the tensile strength of the cloth sample 01 is recorded.

[0035] Further, the inside of the transmission box 43 is provided with a linkage rod shaft 431 and a gear reducer 44, the gear reducer 44 is vertically fixed on the load plate 20, and the gear reducer 44 penetrates the load plate 20, the output end of the gear reducer 44 is in transmission connection with the cloth clamp 30, the input and output ends of the gear reducer 44 are in transmission connection with the linkage rod shaft 431, and the linkage rod shaft 431 is in transmission connection with the transmission belt 421.

[0036] Further, the inside of the transmission box 43 is provided with a bearing seat 432, the bearing seat 432 is provided in two, the bearing seat 432 is fixed on the outer side wall of the load plate 20, and is symmetrically distributed on the linkage rod shaft 431, and the linkage rod shaft 431 is rotatably installed on the bearing seat 432.

[0037] In order to enable the motor 41 to synchronously drive the two ends of the cloth clamp 30 to rotate synchronously, and to ensure that the forces applied to the two sides of the cloth clamp 30 are the same, the transmission area of the transmission belt 421 and the linkage rod shaft 431 is located at the middle position of the linkage rod shaft 431, and the transmission area of the gear reducer 44 and the linkage rod shaft 431 is located at both ends of the linkage rod shaft 431.

[0038] In work, the shaft of the output end of the motor 41 is in transmission connection with the middle part of the linkage rod shaft 431 through the transmission belt 421, and drives the linkage rod shaft 431 to rotate at high speed, the two ends of the linkage rod shaft 431 are connected with two gear reducers 44 respectively, after the linkage rod shaft 431 with low torque and high speed is connected with the gear reducer 44, the speed is reduced, and low speed and high torque are output on the output side of the gear reducer 44, the output end of the gear reducer 44 is in transmission connection with the cloth clamp 30, so that the cloth clamp 30 rotates at low speed and high torque, and the first protective cover 21 is also arranged on the load plate 20 corresponding to the transmission of the gear reducer 44 and the cloth clamp 30, which can protect the internal transmission mechanism.

[0039] As Figure 1 ,Figure 2 and Figure 4 As shown in the figure, in order to detect the tensile strength of the fireproof cloth at the set temperature, the electric heating plate 50 is fixed on the side wall of the load plate 20, the electric heating plate 50 is located at the same side as the cloth clamp 30, and the electric heating plate 50 is located between the two cloth clamps 30.

The spool detection is replaced by rotary winding instead of linear stretching, the spool converts linear stretching into angular displacement, and the product of the rotary radius and the angular velocity is equivalent to the linear velocity, which greatly compresses the stroke requirement, reduces the overall volume of the device, and is especially suitable for production lines or compact laboratories. At the same time, when the roller-type cloth clamp 30 winds the cloth sample 01, the stress on the end of the cloth sample 01 is not concentrated, which can avoid the phenomenon that the cloth sample 01 is loosened from the clamp when the traditional clamp is used.

[0043] The above describes the embodiments, which are not limited, and the drawings only show one of the embodiments, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by it, without departing from the creative purpose, without creative design, similar structure and embodiments of the technical solution can be designed, which shall belong to the protection scope.
