Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a testing device for building energy conservation engineering. Background Technology

[0002] Building energy conservation engineering refers to the engineering field that improves the energy efficiency of buildings during their use by adopting energy-saving materials, products, and equipment for thermal insulation and other treatments. In building energy conservation engineering, the performance of insulation boards is crucial, and their compressive strength is one of the key indicators that must be strictly tested.

[0003] In existing technologies, the compressive strength testing of insulation boards typically employs a testing device comprising a base plate, a gantry frame, and a compressive strength testing structure. During testing, insulation board test blocks cut to standard dimensions must be manually placed on a platform with their edges aligned. However, this method has significant drawbacks: due to the lack of an effective auxiliary positioning mechanism, operators rely entirely on visual inspection and experience to manually center and place the test blocks. This process is not only time-consuming and labor-intensive, but also inefficient in positioning and highly prone to placement errors. If the test blocks are not placed accurately, uneven stress will occur during the compressive strength test, severely affecting the accuracy and reliability of the test data, and may even lead to premature failure of the test blocks due to stress concentration, resulting in test failure.

[0004] Therefore, we propose a testing device for building energy conservation engineering. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a testing device for building energy conservation engineering. Through an automatically lifting positioning mechanism, it achieves rapid and accurate positioning of test blocks, effectively solving the problems of low efficiency and easy deviation in manual placement, thereby improving the accuracy and reliability of compressive strength testing and effectively solving the problems in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a testing device for building energy conservation engineering, comprising a base plate, a gantry bracket installed on the upper part of the base plate, a pressure testing structure installed in the middle of the upper end of the gantry bracket, a loading block fixedly installed in the middle of the upper outer surface of the base plate, an installation cavity opened inside the loading block, and sliding grooves opened on the upper part of the front, rear, left, and right outer surfaces of the loading block, the sliding grooves penetrating into the inner cavity of the loading block, a guide rod vertically fixed in the sliding groove, and a feeding positioning structure installed in the loading block, the feeding positioning structure comprising a lifting arm, a limiting arm, a guide ring, a hydraulic rod, and a cross-shaped support frame, the lifting arm being four sets, the limiting arm being eight sets, the cross-shaped support frame and the hydraulic rod being located in the installation cavity, and the arm of the cross-shaped support frame penetrating through the sliding groove.

[0009] Preferably, the cylinder body of the hydraulic rod is fixed in the middle of the lower end of the inner cavity of the load block, and the upper outer surface of the piston rod of the hydraulic rod is fixedly connected to the middle of the lower outer surface of the cross-shaped support frame.

[0010] Preferably, there are four sets of guide rings, which are fixed at the four ends of the upper outer surface of the cross-shaped support frame, and the guide rings extend to the lower outer surface of the cross-shaped support frame. The guide rods pass through the guide rings, and the inner wall of the guide rings is slidably connected to the outer wall of the guide rods.

[0011] Preferably, the outer surfaces of the four ends of the cross-shaped support frame are fixedly connected to the middle of the inner walls of the four sets of lifting arms, and the outer walls of the four ends of the cross-shaped support frame are slidably connected to the sliding grooves.

[0012] Preferably, the limiting arm is fixed at both ends of the upper outer surface of the lifting arm, and the upper end of the inner wall of the limiting arm is provided with a sloping flared guide groove.

[0013] Preferably, after the piston rod of the hydraulic rod is fully extended, the upper part of the limiting arm protrudes from the upper surface of the carrying block to form a limiting space for accommodating and positioning the test block; after the piston rod of the hydraulic rod is retracted, the upper part of the limiting arm descends to a position no higher than the upper surface of the carrying block.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a testing device for building energy conservation engineering, which has the following beneficial effects:

[0016] 1. This testing device for building energy conservation projects features a liftable loading and positioning structure. When placing a test block, a hydraulic rod drives the limiting arms to rise, and four sets of limiting arms naturally surround and form a standard positioning area. The operator only needs to place the test block into this area to automatically complete the centering, completely eliminating the traditional method of relying on manual visual placement, improving loading efficiency and positioning accuracy, and ensuring that the initial conditions are consistent for each test.

[0017] 2. The testing device for building energy conservation engineering has a flared guide groove on the upper end of the limiting arm, which makes the placement of the test block smoother and has a guiding effect, further reducing the difficulty of operation. At the same time, the cross-shaped support frame ensures that the entire feeding and positioning structure is stable and does not deflect during the lifting process through the sliding cooperation of the guide ring and the guide rod, thereby ensuring the long-term accuracy of positioning and the service life of the device.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-4 As shown, this utility model provides a testing device for building energy conservation engineering, including a base plate 1, with a gantry bracket 2 fixedly installed on the upper part of the base plate 1. A compressive strength testing structure 3 for testing the compressive strength of a test block (such as a thermal insulation board test block) is installed in the middle of the upper end of the gantry bracket 2. A load block 4 for supporting the test block is fixedly installed in the middle of the upper outer surface of the base plate 1.

[0025] The loading block 4 has an internal mounting cavity. Vertical grooves 6 are formed on the upper part of the four end faces (front, rear, left, and right) of the loading block 4. These grooves 6 penetrate the side walls of the loading block 4 and communicate with the internal mounting cavities. A vertical guide rod 7 is fixedly installed in each groove 6.

[0026] A loading and positioning structure 5 is provided inside the mounting cavity of the loading block 4. This loading and positioning structure 5 mainly includes a lifting arm 8, limiting arms 9, a guide ring 11, a hydraulic rod 12, and a cross-shaped support frame 13. There are four sets of lifting arms 8, corresponding to the four sides of the loading block 4. There are eight sets of limiting arms 9, with every two sets of limiting arms 9 fixedly installed at both ends of the upper outer surface of one lifting arm 8. The cross-shaped support frame 13 and the hydraulic rod 12 are both located inside the mounting cavity of the loading block 4, and the four arms of the cross-shaped support frame 13 extend outwards through the corresponding sliding grooves 6.

[0027] The bottom of the cylinder of the hydraulic rod 12 is fixed to the middle of the lower end of the inner cavity of the load block 4. The upper end of the piston rod of the hydraulic rod 12 is fixedly connected to the middle of the lower outer surface of the cross-shaped support frame 13. By extending and retracting the piston rod of the hydraulic rod 12, the cross-shaped support frame 13 can be driven to rise and fall vertically.

[0028] A guide ring 11 is fixed at each of the four ends (near the end of each arm) of the upper outer surface of the cross-shaped support frame 13, and the guide ring 11 passes through the upper and lower surfaces of the cross-shaped support frame 13. The four guide rods 7 pass through the corresponding guide rings 11, and the inner wall of the guide ring 11 and the outer wall of the guide rod 7 form a sliding pair. This cooperation between the guide ring 11 and the guide rod 7 ensures that the cross-shaped support frame 13 can remain stable when raised and lowered under the drive of the hydraulic rod 12, and prevents deflection.

[0029] The four outer surfaces of the cross-shaped support frame 13 (i.e., the ends of each boom) are fixedly connected to the middle of the inner walls of the four sets of lifting booms 8. At the same time, the outer walls of the four ends of the cross-shaped support frame 13 are also slidably connected to the inner walls of the corresponding slide grooves 6, further increasing the stability of lifting.

[0030] Each set of limiting arms 9 has a flared guide groove 10 on the upper inner wall. This flared structure facilitates the automatic sliding and centering of the test block when it is placed in, serving as a guide and centering mechanism.

[0031] The feeding and positioning structure 5 has two working states:

[0032] 1. Positioning State: When the test block needs to be placed, the piston rod of the control hydraulic rod 12 extends fully, pushing the cross-shaped support frame 13 upward. The cross-shaped support frame 13 drives all the limiting arms 9 to rise synchronously through the lifting arm 8 until the upper part of the limiting arm 9 protrudes beyond the upper surface of the load block 4. At this time, the eight sets of limiting arms 9 on the four sets of lifting arms 8 naturally enclose a rectangular limiting space. The size of this space matches the standard test block size, and is used to accurately accommodate and position the test block.

[0033] 2. Testing Status: After the test block is placed in position, the piston rod of the hydraulic rod 12 retracts, pulling the cross-shaped support frame 13 downward, thereby causing all the limiting arms 9 to descend synchronously. When the piston rod of the hydraulic rod 12 has fully retracted, the upper part of the limiting arm 9 descends to a position no higher than the upper surface of the load block 4, completely detaching it from contact with the test block and avoiding interference with the test results during subsequent compressive strength testing.

[0034] Working principle:

[0035] During the compression test, the operator first activates hydraulic rod 12 to position the loading and positioning structure 5 (limiting arm 9 rises). Then, a standard-sized test block is placed within the limiting space formed by eight sets of limiting arms 9. Because the upper end of each limiting arm 9 has a flared guide groove 10, the test block can be easily guided to the accurate center position, achieving rapid and precise alignment. After the test block is securely placed, hydraulic rod 12 is activated again to switch the loading and positioning structure 5 to the detection state (limiting arm 9 descends). The limiting arms 9 descend below the upper surface of the load block 4 and no longer contact the test block. Finally, the compression detection structure 3 is activated to perform the compression strength test. After the test is completed, the test block can be removed.
