Description

Technical Field

[0001] The utility model relates to the technical field of compression-shear testing machines, and particularly relates to a rubber bearing compression-shear testing machine which is convenient for positioning and placing. Background Technique

[0002] A rubber bearing is a bridge bearing composed of steel components and rubber. The rubber bearing is used to connect the box girder and the pier and plays a crucial role in the bridge. After the rubber bearing is produced by the manufacturer, it is necessary to conduct a compression-shear test on the rubber bearing to test the maximum pressure and maximum shear force that the rubber bearing can withstand.

[0003] At present, the Chinese patent discloses a rubber bearing compression-shear testing machine (publication number: CN217180390U). In this application, by setting a testing machine body and a first hydraulic cylinder, the first hydraulic cylinder applies a shear force to the rubber bearing, thereby reducing the situation where the staff needs to manually lift the rubber seat when detecting the shear force of the rubber bearing, and further reducing the waste of labor when detecting the rubber bearing.

[0004] Since the above device directly places the rubber bearing on the lower support plate for the compression-shear test, its placement position is uncertain. However, an incorrect placement position may cause the rubber bearing to slide or shift during the test, which may lead to the failure of the test and requires re-conducting, thus wasting time and resources.

[0005] Therefore, a rubber bearing compression-shear testing machine which is convenient for positioning and placing is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a rubber bearing compression-shear testing machine which is convenient for positioning and placing in order to solve the above problems, and improves the problem that the existing rubber bearing compression-shear testing machine is difficult to position and place the rubber bearing, increasing the experimental error and the probability of experimental failure.

[0007] The utility model realizes the above object through the following technical solutions. A rubber bearing compression-shear testing machine convenient for positioning and placing includes: an electro-hydraulic servo rubber bearing compression-shear testing machine, a slide rail, and an electric rail car. The slide rail is installed on the surface of the electro-hydraulic servo rubber bearing compression-shear testing machine, and the electric rail car is slidably connected to the surface of the slide rail; a positioning device is installed on the surface of the electric rail car; two sliding openings are provided at one end of the electric rail car. The positioning device includes a horizontal positioning mechanism and a vertical positioning mechanism. The horizontal positioning mechanism is fixedly connected to the top of the electric rail car, the vertical positioning mechanism is installed inside the sliding opening, one end of the vertical positioning mechanism penetrates above the electric rail car, and the horizontal positioning mechanism and the vertical positioning mechanism intersect. The positioning device can lock and place the rubber bearing on the top of the electric rail car, which not only effectively reduces the probability of increased experimental errors or even experimental failures caused by incorrect placement of the rubber bearing, but also can prevent the rubber bearing from separating from the electric rail car during detection or movement, thus ensuring the detection effect of subsequent compression-shear tests.

[0008] Preferably, the horizontal positioning mechanism includes a fixed horizontal positioning strip and a threaded seat. Both the fixed horizontal positioning strip and the threaded seat are fixedly connected to the top of the electric rail car. A first threaded column is threadedly connected inside the threaded seat. One end of the first threaded column is fixedly connected to a movable horizontal positioning strip that is slidably connected to the electric rail car. This can position the two ends of the rubber bearing and reduce the probability of the rubber bearing separating from the electric rail car during detection or movement.

[0009] Preferably, the vertical positioning mechanism includes a bidirectional lead screw rotatably connected inside the electric rail car. One end of the bidirectional lead screw sequentially penetrates through one of the sliding openings and the other sliding opening and extends to the outside of the electric rail car. Slide frames that are slidably connected to the sliding openings are threadedly connected to the surfaces of the two opposite threads of the bidirectional lead screw. A vertical movable positioning strip that is slidably connected to the top of the electric rail car is fixedly connected to the top of the slide frame. The fixed horizontal positioning strip and the movable horizontal positioning strip both intersect with the vertical movable positioning strip. This can not only place the rubber bearing in the center and make its placement position more accurate, but also limit the two ends of the rubber bearing perpendicular to the fixed horizontal positioning strip, further reducing the probability of the rubber bearing separating from the electric rail car during detection or movement.

[0010] Preferably, the fixed horizontal positioning strip and the movable horizontal positioning strip are symmetrically distributed on both sides of the center point of the electric rail car. The fitting surface of the movable horizontal positioning strip and the electric rail car is rectangular. This can ensure that the fixed horizontal positioning strip and the movable horizontal positioning strip are large enough to place rubber bearings of different specifications, and at the same time, it also limits that the movable horizontal positioning strip can only move horizontally.

[0011] Preferably, the other end of the first threaded post is fixedly connected with a first adjusting handle, and the first adjusting handle has a rounded corner, which enables the experimenter to rotate the first threaded post more stably and easily, so as to facilitate the experimenter to perform positioning operations.

[0012] Preferably, two rubber bellows are sleeved on the surface of the first threaded post. One of the rubber bellows is fixedly connected between the threaded seat and the first adjusting handle, and the other rubber bellows is fixedly connected between the threaded seat and the movable horizontal positioning bar. This can locally wrap the part of the first threaded post exposed outside the threaded seat, preventing experimental debris or dust from falling on the part of the first threaded post exposed to the outside world, and thus ensuring the normal operation of the first threaded post.

[0013] Preferably, a ring groove is formed at one end of the threaded seat, and one end of the other rubber bellows penetrates into the inside of the ring groove and is fixedly connected with the ring groove, which can provide enough telescopic space for the other rubber bellows and avoid the probability of damage to the other rubber bellows due to excessive compression.

[0014] Preferably, the other end of the bidirectional lead screw is fixedly connected with a second adjusting handle, and the corners of the second adjusting handle have rounded corners, which enables the experimenter to rotate the second adjusting handle more stably and easily, so as to facilitate the experimenter to perform positioning operations.

[0015] The beneficial effects of the present utility model are as follows:

[0016] The positioning device can lock and place the rubber bearing on the top of the electric rail vehicle, which not only effectively reduces the probability of increasing experimental errors due to incorrect placement of the rubber bearing, or even causing experimental failure, but also can prevent the rubber bearing from separating from the electric rail vehicle during the detection or movement process, thereby ensuring the detection effect of the subsequent compression-shear test.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] During specific implementation: As Figures 1-4 shown, a rubber bearing compression-shear testing machine that is convenient for positioning and placing includes: an electro-hydraulic servo rubber bearing compression-shear testing machine 1, a slide rail 2, and an electric rail vehicle 3. The slide rail 2 is installed on the surface of the electro-hydraulic servo rubber bearing compression-shear testing machine 1, and the electric rail vehicle 3 is slidably connected to the surface of the slide rail 2; a positioning device 4, and the positioning device 4 is installed on the surface of the electric rail vehicle 3; two slide openings 31 are opened at one end of the electric rail vehicle 3. The positioning device 4 includes a transverse positioning mechanism 41 and a longitudinal positioning mechanism 42. The transverse positioning mechanism 41 is fixedly connected to the top of the electric rail vehicle 3, and the longitudinal positioning mechanism 42 is installed inside the slide opening 31. One end of the longitudinal positioning mechanism 42 penetrates above the electric rail vehicle 3, and the transverse positioning mechanism 41 intersects with the longitudinal positioning mechanism 42. It should be noted that the electro-hydraulic servo rubber bearing compression-shear testing machine 1 is a currently common machine for performing compression-shear tests on rubber bearings. Since this application does not improve the compression-shear test process and operation method, the specific structure and usage method of the electro-hydraulic servo rubber bearing compression-shear testing machine 1 are also the same as the existing public technologies and will not be elaborated here.

[0024] As Figure 3 and Figure 4As shown, the horizontal positioning mechanism 41 includes a fixed horizontal positioning bar 411 and a threaded seat 412. Both the fixed horizontal positioning bar 411 and the threaded seat 412 are fixedly connected to the top of the electric rail vehicle 3. A first threaded column 413 is threadedly connected to the inner side of the threaded seat 412. One end of the first threaded column 413 is fixedly connected to a movable horizontal positioning bar 414 that is slidably connected to the electric rail vehicle 3. The fixed horizontal positioning bar 411 and the movable horizontal positioning bar 414 are symmetrically distributed on both sides of the center point of the electric rail vehicle 3. The mating surface of the movable horizontal positioning bar 414 and the electric rail vehicle 3 is rectangular. The other end of the first threaded column 413 is fixedly connected to a first adjusting handle 415, and the first adjusting handle 415 has rounded corners. The surface of the first threaded column 413 is sleeved with two rubber bellows 416. One of the rubber bellows 416 is fixedly connected between the threaded seat 412 and the first adjusting handle 415, and the other rubber bellows 416 is fixedly connected between the threaded seat 412 and the movable horizontal positioning bar 414. One end of the threaded seat 412 is provided with an annular groove 4121, and one end of the other rubber bellows 416 penetrates into the interior of the annular groove 4121 and is fixedly connected to the annular groove 4121.

[0025] As Figure 3 and Figure 4 shown, the vertical positioning mechanism 42 includes a bidirectional lead screw 421 rotatably connected to the inside of the electric rail vehicle 3. One end of the bidirectional lead screw 421 sequentially penetrates through one of the sliding openings 31 and the other sliding opening 31 and extends to the outside of the electric rail vehicle 3. Sliding brackets 422 that are slidably connected to the sliding openings 31 are threadedly connected to the surfaces of the two opposite threads of the bidirectional lead screw 421. The top of the sliding bracket 422 is fixedly connected to a vertically movable positioning bar 423 that is slidably connected to the top of the electric rail vehicle 3. Both the fixed horizontal positioning bar 411 and the movable horizontal positioning bar 414 intersect with the vertically movable positioning bar 423. One end of the bidirectional lead screw 421 is fixedly connected to a second adjusting handle 424, and the corners of the second adjusting handle 424 have rounded corners.

[0026] When the utility model is in use, after an experimenter places the rubber bearing on the top of the electric rail vehicle 3, the experimenter first makes one end of the rubber bearing fit with the fixed horizontal positioning strip 411, and then rotates the first threaded column 413 in the corresponding direction. The first threaded column 413 spirally approaches the rubber bearing along the threaded seat 412. The first threaded column 413 drives the movable horizontal positioning strip 414 to slide along the electric rail vehicle 3 and approach the rubber bearing until it fits with the other end of the rubber bearing. Then the experimenter rotates the longitudinal double lead screw 421 in the corresponding direction. The double lead screw 421 drives two sliding frames 422 to slide towards each other along the sliding openings 31 connected thereto through two opposite threads on the surface. The sliding frames 422 drive the longitudinal movable positioning strips 423 to approach one end of the rubber bearing perpendicular to the fixed horizontal positioning strip 411 until both longitudinal movable positioning strips 423 fit with the rubber bearing. At this time, the rubber bearing is locked on the top of the electric rail vehicle 3, effectively reducing the probability that the experimental error is increased or even the experiment fails due to incorrect placement of the rubber bearing. Moreover, this can effectively limit the rubber bearing on the top of the electric rail vehicle 3, preventing the rubber bearing from separating from the electric rail vehicle 3 during the detection or movement process, thus ensuring the detection effect of the subsequent compression-shear test. Then the staff can manually control the movement of the electric rail vehicle 3. The electric rail vehicle 3 moves the rubber bearing along the slide rail 2 towards the electro-hydraulic servo rubber bearing compression-shear testing machine 1 through the positioning device 4 until the rubber bearing is moved to the specified position in the electro-hydraulic servo rubber bearing compression-shear testing machine 1. Then the experimenter can manually turn on the electro-hydraulic servo rubber bearing compression-shear testing machine 1 to normally conduct the compression-shear test on the rubber bearing.

[0027] It should be noted that in the above description, the electro-hydraulic servo rubber bearing compression-shear testing machine 1, the slide rail 2, the electric rail vehicle 3 and the double lead screw 421 are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the electro-hydraulic servo rubber bearing compression-shear testing machine 1 and the electric rail vehicle 3 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0028] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
