Description

Technical Field

[0001] This utility model relates to the technical field of grouting and filling simulation experimental device for overburden isolation, specifically a grouting and filling simulation experimental device for overburden isolation. Background Technology

[0002] The overburden isolation grouting and filling simulation experimental device is an experimental device used to simulate and study the use of grouting technology for rock layer reinforcement and isolation in underground mining, tunnel construction and other engineering projects. By simulating the rock layer conditions in actual engineering projects, this device helps researchers understand and optimize the overburden isolation grouting and filling technology to improve the safety and stability of underground engineering projects.

[0003] In some current simulated rock grouting and filling experimental devices, when different simulated rock layers are placed, the depth of the simulation test chamber makes it inconvenient for staff to lay the bottom simulated rock layer material. At the same time, after the experiment is completed, it is also inconvenient for staff to clean the bottom simulated rock layer material, thus reducing the effectiveness of the device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a simulated experimental device for grouting and filling of overburden isolation, which has advantages such as convenient arrangement of simulated rock layers and solves the problems of inconvenience in arranging simulated rock layers and removing simulated rock layer materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simulated experimental device for grouting and filling of overburden isolation, comprising a simulation box, a support block installed inside the simulation box, a base plate installed above the support block inside the simulation box, a threaded sleeve installed at the middle position of the bottom end face of the simulation box, a threaded rod threadedly connected inside the threaded sleeve, the top end of the threaded rod penetrating the bottom of the simulation box and rotatably connected to the bottom end face of the base plate, a pair of mounting blocks installed on both sides of the upper end of the simulation box, a connecting groove provided on the upper end face of the mounting blocks, a fixing mechanism installed on one side of the mounting blocks, and a box cover, a pair of L-shaped connecting blocks installed on both sides of the box cover, a slot provided on one side of the L-shaped connecting blocks, a plurality of insertion holes provided on the upper end face of the box cover, and a hole cap installed at the top of the insertion holes.

[0006] Furthermore, the fixing mechanism includes a pulling block, a locking pin, and a tension spring. A locking pin is movably connected to one side of the mounting block. One end of the locking pin passes through one side of the mounting block and extends into the connecting groove. The other end of the locking pin is fitted with a pulling block. One end of the locking pin matches the size of the locking groove.

[0007] Furthermore, a stop is rotatably connected to one side of the pulling block.

[0008] Furthermore, two pairs of support legs are installed on both sides of the bottom end face of the simulation box, one of which has a support plate installed on one side, and a controller is installed on the upper end face of the support plate.

[0009] Furthermore, a rotating handle is installed on the bottom end face of the threaded rod.

[0010] Furthermore, a pair of lifting handles are installed on both sides of the upper end face of the box lid.

[0011] Furthermore, a rubber pad is installed on the upper surface of the support block.

[0012] Furthermore, the simulation box is made of transparent material.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This simulated experimental device for grouting and filling grouting in overburden isolation utilizes a rotating handle, threaded rod, threaded sleeve, and base plate. The up-and-down movement of the threaded rod drives the up-and-down movement of the base plate. When it is necessary to lay simulated rock layer material, the base plate is moved to the upper part of the simulation box near the opening, making it convenient for workers to lay the simulated rock layer material. After each layer is laid, the base plate is controlled to move downwards a certain distance. When it is necessary to remove the simulated rock layer material, simply control the base plate to move upwards, which in turn moves the simulated rock layer material upwards, making it convenient for workers to remove the simulated rock layer material, thereby improving the effectiveness of the device.

[0015] 2. This grouting and filling simulation experimental device for overburden isolation utilizes a combination of a stop block, a pulling block, a tension spring, a locking pin, a locking groove, and an L-shaped connecting block. When the box cover needs to be installed, the operator moves the pulling block to one side, causing the locking pin to move to the outside of the connecting groove. Then, the stop block is rotated so that it abuts against one side of the installation block, at which point the locking pin cannot move. Next, the L-shaped connecting block of the box cover is inserted into the connecting groove, and the stop block is rotated again to disengage from the installation block. At this point, under the force of the tension spring, the tension spring pulls the locking pin into the locking groove through the pulling block, thus fixing the box cover. The reverse operation allows for quick removal of the box cover, thereby achieving the effect of rapid installation and removal of the box cover. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This embodiment of a simulated experimental device for grouting and filling of overburden isolation includes a simulation box 1, a support block 2 installed inside the simulation box 1, a base plate 3 installed above the support block 2 inside the simulation box 1, a threaded sleeve 101 installed in the middle of the bottom end face of the simulation box 1, a threaded rod 4 threadedly connected inside the threaded sleeve 101, the top end of the threaded rod 4 passing through the bottom of the simulation box 1 and rotatably connected to the bottom end face of the base plate 3, a pair of mounting blocks 5 installed on both sides of the upper end of the simulation box 1, a connecting groove 501 provided on the upper end face of the mounting block 5, a fixing mechanism 6 installed on one side of the mounting block 5, and a box cover 7. A pair of L-shaped connecting blocks 8 are installed on both sides of the box cover 7, a slot 801 provided on one side of the L-shaped connecting block 8, and several insertion holes 9 provided on the upper end face of the box cover 7, with a hole cover 901 installed at the top of the insertion hole 9. By rotating the handle 401, the threaded rod 4 is driven to rotate. Since the threaded rod 4 is threadedly connected to the threaded sleeve 101, the rotation of the threaded rod 4 drives the base plate 3 to move upward.

[0024] The fixing mechanism 6 includes a pull block 601, a locking pin 602 and a tension spring 603. The locking pin 602 is movably connected to one side of the mounting block 5. One end of the locking pin 602 passes through one side of the mounting block 5 and extends into the connecting groove 501. The pull block 601 is installed at the other end of the locking pin 602. One end of the locking pin 602 matches the size of the groove 801.

[0025] Among them, a stop block 604 is rotatably connected to one side of the pulling block 601.

[0026] It should be understood that by moving the pull block 601 to one side, the locking pin 602 is moved to the outside of the connecting groove 501, and the stop block 604 is rotated so that the stop block 604 abuts against one side of the mounting block 5. At this time, the locking pin 602 cannot move. Then, the L-shaped connecting block 8 of the box cover 7 is inserted into the connecting groove 501, and the stop block 604 is rotated again so that the stop block 604 is disengaged from the mounting block 5. At this time, under the force of the tension spring 603, the tension spring 603 pulls the locking pin 602 into the slot 801 through the pull block 601 and fixes the box cover 7.

[0027] The simulation box 1 has two pairs of support legs 102 installed on both sides of its bottom end face. One of the support legs 102 has a support plate 103 installed on one side, and the upper end face of the support plate 103 has a controller 10 installed on it.

[0028] It should be understood that controller 10 has a control effect.

[0029] The bottom end face of the threaded rod 4 is equipped with a rotating handle 401.

[0030] It should be understood that rotating the handle 401 facilitates the rotation of the threaded rod 4.

[0031] Among them, a pair of lifting handles 701 are installed on both sides of the upper end face of the box cover 7.

[0032] It should be understood that the lid 7 is easily moved by pulling the handle 701.

[0033] Among them, a rubber pad 201 is installed on the upper end surface of the support block 2.

[0034] It should be understood that the rubber pad 201 can provide a cushioning effect when the bottom surface of the base plate 3 contacts the upper surface of the support block 2.

[0035] Among them, simulation box 1 is made of transparent material.

[0036] It should be understood that transparent materials facilitate observation during simulation experiments.

[0037] The working principle of the above embodiments is as follows:

[0038] First, rotating the handle 401 drives the threaded rod 4 to rotate. Since the threaded rod 4 is threadedly connected to the threaded sleeve 101, the rotation of the threaded rod 4 causes the base plate 3 to move upward. When it approaches the opening of the box, the movement stops. Then, the worker lays the simulated rock layer material on the base plate 3. After the first layer of simulated rock layer is laid, the base plate 3 is controlled to continue moving downward a certain distance. Multiple layers of simulated rock layer are laid in this way. Then, the pull block 601 is moved to one side, causing the locking pin 602 to move to the outside of the connecting groove 501. Then rotate the stop block 604 so that it abuts against one side of the mounting block 5. At this time, the locking pin 602 cannot move. Then insert the L-shaped connecting block 8 of the box cover 7 into the connecting groove 501. Then rotate the stop block 604 so that it disengages from the mounting block 5. At this time, under the action of the tension spring 603, the tension spring 603 pulls the locking pin 602 into the groove 801 through the pulling block 601 and fixes the box cover 7. Open the hole cover 901 and insert the grouting device into the simulated rock layer in the simulation box 1 to conduct a simulation experiment.
