[0002] Polymer mortar is a new type of concrete composite material that combines the adhesiveness of polymer materials and the durability of inorganic materials. This type of mortar is usually mixed with polymers, cement, fine aggregates and admixtures in a certain proportion. As a new type of building material, in order to ensure that polymer mortar has good compression resistance, tensile resistance, wear resistance, etc., testing related properties is a key link to ensure its quality and applicability. However, the existing related testing equipment can usually only test a single property of the mortar, but cannot test the mortar in multiple directions, resulting in the need for more types of related equipment to assist in testing, which requires high costs, and it is also cumbersome to operate multiple equipment to test mortar samples one by one, and there are limitations in its use.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model discloses a polymer mortar performance testing device, including a base 1, on which an adjusting disk 2 is rotatably installed, wherein the top wall of the adjusting disk 2 has a spiral linkage pattern, and two relatively distributed guide sleeves 3 are installed on the base 1, and relatively distributed detection arms 4 are retractably installed in the two guide sleeves 3, wherein the bottom of the detection arm 4 is fixedly connected with a plurality of teeth 5 that extend interlacedly to the gaps at each circle of the linkage pattern. When in use, a mortar sample or two objects bonded by mortar are placed between the two detection arms 4, and then the adjusting disk 2 is rotated to drive the two detection arms 4 to move to one side close to or away from the center of the base 1, and the adjustment is used to squeeze the mortar sample and stretch the two objects bonded by mortar for performance testing.

[0027] In one embodiment, a wear resistance detection device 12 is provided on the base 1, and the wear resistance detection device 12 is used to rub the mortar sample located between the two detection arms 4 from bottom to top. A rotating shaft 7 is rotatably installed on the base 1, and a gear A 8 is installed on the rotating shaft 7 so as to be liftable. The gear A 8 can be lifted and lowered on the rotating shaft 7 to different heights, and is used to drive the adjustment disk 2 or the wear resistance detection device 12 to perform rotation adjustment. A limiting device 9 is provided on the gear A 8, and the limiting device 9 is used to limit the gear A 8 to the corresponding height of the rotating shaft 7. A driving device is also installed on the base 1, and the driving device is used to drive the rotating shaft 7 to rotate, and the driving device can be a motor device.

[0028] In a specific implementation, when it is necessary to perform a corresponding test on the polymer mortar, a polymer mortar block of a corresponding size or two objects bonded by polymer mortar can be prepared in advance. When it is necessary to perform a compression test on the mortar, the mortar block is placed between the two detection arms 4, and then the rotating shaft 7 is driven to rotate by the driving device. At this time, the gear A 8 on the rotating shaft 7 is linked to the adjusting disk 2, so when the rotating shaft 7 rotates, the gear A 8 rotates synchronously and drives the adjusting disk 2 to rotate, so that the two detection arms 4 move in the guide sleeve 3 under the rotation of the vortex-shaped linkage pattern. The two detection arms 4 approach each other and squeeze the mortar block to perform corresponding detection. When it is necessary to test the adhesion of the mortar, two objects bonded by the polymer mortar are placed between the two detection arms 4. According to the application of the prior art, structures such as rings are fixed on the two objects, and hooks are installed at the two detection arms 4. The hooks pass through the rings to prepare the objects to be detected. Then the adjusting disk 2 is driven to rotate in the opposite direction to move the two detection arms 4 to the end away from the object to be detected. The two detection arms 4 pull the two objects respectively until the two objects are separated from the bonding part of the polymer mortar. When it is necessary to test the wear resistance of the mortar, the gear A 8 on the rotating shaft 7 is lowered to the linkage wear resistance detection device 12. When the rotating shaft 7 rotates, the gear A 8 rotates synchronously and drives the wear resistance detection device 12 to rotate. The rotating linked wear resistance detection device 12 rubs the mortar sample located between the two detection arms 4 from bottom to top, thereby performing a wear resistance test on the mortar sample. In actual situations, corresponding reading instruments can be equipped on the device to facilitate a very intuitive understanding of the compressive strength of the mortar under specified conditions, the bonding properties of the mortar under tension, and the ability of the mortar to maintain its structure and performance when subjected to wear and friction. The device is easy to operate and can perform performance tests on the mortar in different directions, thereby facilitating actual use.

[0029] In one embodiment, a gear ring 6 and a sprocket set 10 are rotatably mounted on the base 1, wherein the gear ring 6 is connected to the adjustment disk 2, a gear B11 is mounted on one end of the sprocket set 10, and the other end of the sprocket set 10 is connected to the wear resistance detection device 12.

[0030] In a specific implementation, the rotating gear B11 is used to drive the sprocket set 10 to drive the wear resistance detection device 12 to rotate, and the ring gear 6 and the gear B11 are respectively engaged with the gear A 8 at different heights on the rotating shaft 7. Therefore, when the operator adjusts the gear A 8 to different heights on the rotating shaft 7, the gear A 8 will engage with the ring gear 6 or the gear B11, and the driving device drives the rotating shaft 7 to rotate, thereby driving the ring gear 6 or the gear B11 to rotate separately.

[0031] In one embodiment, the limiting device 9 includes a retractable latch 91 installed on the gear A 8 and a pull rod 92 connected to the latch 91. In particular, a spring for squeezing the latch 91 is surrounded on the pull rod 92, and two groups of lock holes 14 at different heights are opened on the rotating shaft 7. The spring squeezes the latch 91 so that it is inserted into the lock holes 14 at different heights, so that the gear A 8 is limited at different height positions on the rotating shaft 7 and rotates synchronously with the rotating shaft 7.

[0032] In a specific implementation, the pull rod 92 is pulled to the side away from the rotating shaft 7, so that the latch 91 moves accordingly and disengages from the lock hole 14. At this time, the gear A 8 is released from the limited state, so that it can be adjusted up and down on the rotating shaft 7. Conversely, when the gear A 8 needs to remain in a fixed state, the gear A 8 is adjusted to a corresponding height. At this time, the latch 91 is aligned with the corresponding lock hole 14, and the spring squeezes the latch 91 so that it is inserted into the lock hole 14 at that location, so that the gear A 8 is fixed to the rotating shaft 7. In this state, when the rotating shaft 7 rotates, the gear A 8 will also rotate and adjust synchronously.

[0033] In one embodiment, the wear resistance detection device 12 includes a sleeve 121 rotatably mounted on the base 1, a rod 122 liftably mounted on the sleeve 121, and a friction block 123 mounted on the rod 122, and the sprocket group 10 includes two sprockets and a chain connected to the two sprockets, one of the sprockets is mounted on the outer wall of the sleeve 121, and the other sprocket is mounted on the gear B11, and the friction block 123 is used to rub the mortar sample.

[0034] In a specific implementation, when gear A8 is meshed with gear B11, the rotation of gear A8 drives gear B11 and the sprocket connected to gear B11 to rotate. At this time, the chain transmission drives another sprocket to rotate, so that the sleeve 121 rotates together. Moreover, since the rod body 122 is installed on the sleeve body 121 in a liftable manner, it can be raised and lowered so that the friction block 123 does not contact the mortar sample when not in use, and contacts the mortar sample when in use, so as to improve the detection flexibility.

[0035] In one embodiment, a clamping plate 13 is installed at one end of the detection arm 4 close to the mortar sample, and a threaded hole 15 is provided inside the clamping plate 13. The threaded hole 15 is used to install a hook tool, which is used to hook the mortar sample with a fixing ring.

[0036] In one embodiment, an external thread 124 is provided on the outer wall of the rod body 122 in the same direction as the rotation direction of the sleeve body 121, and an internal thread corresponding to the rotation direction is provided on the inner wall of the sleeve body 121. When in use, the sleeve body 121 rotates and drives the rod body 122 to rotate along the rotation direction of the external thread 124, so that the friction block 123 continuously contacts the mortar sample to ensure that the friction block 123 contacts and rubs with the mortar sample, and the clamping plate 13 is L-shaped in shape, facing horizontally upward and pressing the mortar sample, so that the mortar sample will not be pushed out of between the two detection arms 4 by the wear resistance detection device 12 to ensure the friction effect.
