Description

Technical Field

[0001] The utility model relates to the technical field of tests, in particular to a material testing machine for high-efficiency curtain wall projects. Background Technique

[0002] A material testing machine for high-efficiency curtain wall projects is a device dedicated to testing and evaluating the performance of curtain wall materials. A curtain wall is a decorative structural system for building facades, commonly used in large buildings, and its main functions are to beautify the building appearance, improve building energy efficiency, heat insulation, sound insulation, etc.

[0003] During the production process of high-efficiency curtain wall materials, the following tests are usually carried out:

[0004] Wind pressure resistance test: used to simulate the wind force under actual use conditions and test the wind pressure resistance of curtain wall materials and structures.

[0005] Water penetration resistance test: used to test the waterproof performance of curtain wall materials and structures under different water pressures to evaluate their ability to resist rainwater penetration.

[0006] Impact resistance test: used to evaluate the impact resistance of curtain wall materials to determine their ability to withstand external impacts.

[0007] Heat insulation performance test: used to evaluate the heat insulation performance of curtain wall materials, including indicators such as heat transfer coefficient and heat preservation performance.

[0008] Sound performance test: used to evaluate the sound insulation effect of curtain wall materials and structures on noise.

[0009] Impact refers to a structural system being subjected to an instantaneous load, which can also be regarded as a short process of energy transfer from the outside to a structural system.

[0010] After retrieval, the patent with the publication number CN213148528U discloses a plastic material impact testing machine, including a base, a column, and a crossbeam. The base is fixedly connected to the column. A moving block is slidably connected to the outside of the column. A ball support is fixedly connected to the inside of the moving block. A steel ball is slidably connected to the inside of the top end of the ball support. A moving plate is slidably connected to the bottom end of the steel ball. The bottom end of the moving plate is slidably connected to the ball support. An electric telescopic rod is fixedly connected to the right side of the moving plate. The electric telescopic rod is fixedly connected to the ball support. In this utility model, through the set ball support, steel ball, electric telescopic rod, and moving plate, this setting cooperates with the sliding connection between the ball support and the steel ball and the fixed connection between the electric telescopic rod and the moving plate. The structure is relatively simple. When it is necessary to change the force of free-fall descent, it can be easily achieved by simply replacing steel balls of different sizes, which is not only simple but also reduces the test cost.

[0011] The following problems exist in this technical solution:

[0012] Although an impact test can be performed on the material, personnel cannot be protected during the test. During the impact test, the material is prone to breakage, and the debris splashes, which can easily injure the staff and result in low safety. Utility Model Content

[0013] The purpose of the present utility model is to solve the drawbacks in the prior art that although an impact test can be performed on the material, personnel cannot be protected during the test. During the impact test, the material is prone to breakage, and the debris splashes, which can easily injure the staff and result in low safety. A material testing machine for high-efficiency curtain wall engineering is proposed.

[0014] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0015] A material testing machine for high-efficiency curtain wall engineering, including a housing. A first electric push rod is fixedly arranged on the inner wall of the top of the housing. The telescopic part of the first electric push rod is fixedly provided with a cover body. An L-shaped plate is slidably connected to the inner wall of the bottom of the cover body. A steel ball for performing an impact test is placed on the top of the L-shaped plate. A partition is fixedly arranged on the inner wall of the top of the cover body. A second electric push rod is fixedly arranged on one side of the cover body. The telescopic part of the second electric push rod penetrates through one side of the cover body and is fixedly connected to one side of the L-shaped plate. A falling hole for the steel ball to fall is opened on one side of the bottom of the cover body. A box door for preventing material splashing is hinged to one side of the housing;

[0016] A fixing mechanism is arranged on the housing and the box door to fix the box door;

[0017] A placing mechanism is arranged on one side of the housing to place steel balls of different specifications and sizes.

[0018] In a possible design, the fixing mechanism includes a first plug board, a second plug board and a plug rack for fixing the box door. One side of the first plug board is fixedly connected to one side of the housing. One side of the second plug board is fixedly connected to one side of the box door. Plug holes are opened on both the first plug board and the second plug board. The two ends of the plug rack are respectively inserted into the plug holes of the first plug board and the second plug board.

[0019] In a possible design, the placing mechanism includes a placing box for placing steel balls of different specifications and sizes. One side of the placing box is fixedly connected to one side of the housing.

[0020] In a possible design, a collection box for collecting debris is placed on the inner wall of the bottom of the housing.

[0021] In a possible design, an indicating needle for indication is fixedly arranged on one side of the cover body, and a scale line for height marking is fixedly arranged on the inner wall of one side of the housing.

[0022] In a possible design, a limiting plate for limiting the steel ball is fixedly arranged on one side of the cover body.

[0023] In this application, during use, place the curtain wall material in the collection box and below the falling hole, then take a suitable steel ball from the placement box and place the steel ball on the L-shaped plate. The provided limiting plate can limit the steel ball to prevent it from rolling out of the cover body. One side of the cover body is in a closed state so that the steel ball will not roll out from the other side of the cover body. Start the first electric push rod. The expansion and contraction of the telescopic part of the first electric push rod drives the movement of the cover body. The movement of the cover body drives the movement of the steel ball and the indicating needle. After moving to the height where the test is required, close the box door. The box door rotates through the hinge. After the box door fits against one side of the housing, take the insertion rack and insert the two bottom ends of the insertion rack into the jacks of the first insertion plate and the second insertion plate, so as to fix the box door. Then start the second electric push rod. The expansion and contraction of the telescopic part of the second electric push rod drives the movement of the L-shaped plate. When the L-shaped plate and the steel ball are disengaged, the steel ball will fall onto the curtain wall material through the falling hole. The steel ball is affected by gravity and freely falls to conduct an impact test on the material. Personnel can visually observe the damage degree on the surface of the material. The box door and the housing can resist the splashed debris during the test to protect personnel and improve safety. The generated debris will be in the collection box, which is convenient for centralized treatment. The provided placement box can place multiple steel balls of different specifications. The material of the box door is transparent acrylic material, which is convenient for observing the situation inside the housing.

[0024] The beneficial effects in this utility model are as follows:

[0025] In this utility model, for the high-efficiency material testing machine for curtain wall engineering, by the fixing mechanism, insert the two bottom ends of the insertion rack into the jacks of the first insertion plate and the second insertion plate, so as to fix the box door;
