Description

Technical Field

[0001] This utility model relates to the technical field of grout flowability testing devices, and in particular to a flowability testing device for tunnel grouting. Background Technology

[0002] The tunnel grouting flowability testing device is a specialized device used to test the flowability of grouting materials in tunnel grouting projects. This device can accurately detect the flowability of grouting materials, providing important quality control parameters for tunnel grouting construction, ensuring that the grouting effect meets the project requirements, and playing a key role in tunnel construction.

[0003] Existing technologies, such as the utility model patent with publication number CN213933470U, disclose a cement mortar flowability testing device. This patent uses a base, a frame set on the upper end of the base, a disc set on the frame, a conical mold set on the upper end of the disc, a support rod rotatably set on the upper end of the base, a groove opened on the side of the support rod near the disc, a rotating component set on the upper end of the base for driving the support rod to rotate, and an adjusting mechanism set on the side of the groove near the disc for adjusting the position of the conical mold. This solves the problem that existing cement mortar flowability testing devices require workers to lift the entire conical mold by hand during use, which can easily cause the conical mold to move the cement mortar and affect the accuracy of the test data.

[0004] In the process of testing mortar fluidity using testing devices, most existing testing devices on the market have large support structures to ensure the stability of the device during the testing process. This increases the difficulty for testing personnel to move the equipment due to interference from the support structure during on-site testing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the support structure is too large, increasing the difficulty for inspectors to move equipment during on-site inspections due to interference from the support structure. Therefore, this invention proposes a flowability testing device for tunnel grouting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flowability detection device for tunnel grouting, comprising a cylinder and a feeding cylinder, wherein the feeding cylinder is fixedly connected to the lower surface of the cylinder and communicates with the interior of the cylinder; an assisting component is provided on the outer circumference of the cylinder, the assisting component includes a support unit, the support unit includes an assembly frame, the assembly frame is fixedly connected to the outer circumference of the cylinder, a support frame is rotatably connected to the shaft of the assembly frame, a lead screw is rotatably connected to the inner wall of the support frame, an anti-slip wheel is fixedly connected to the arc surface of the lead screw, an extension frame is slidably connected to the inner wall of the support frame, a linkage nut is fixedly connected to the inner wall of the extension frame, the linkage nut is threadedly connected to the surface of the lead screw, and a spherical rotating shaft is fixedly connected to the end of the extension frame away from the assembly frame, and a universal support foot is installed on the arc surface of the spherical rotating shaft;

[0007] The assisting component also includes a locking unit, which includes a swivel shaft. The swivel shaft is fixedly connected to the side surface of the support frame. The side surface of the support frame has a storage cavity. A connecting plate is slidably connected to the inner wall of the storage cavity. A connecting rod is fixedly connected to the side surface of the connecting plate. A limit spring is fixedly connected to one side of the connecting plate and the connecting rod. The side of the limit spring away from the connecting plate is fixedly connected to the inner wall of the storage cavity. A fixing sleeve is fixedly connected to the side of the connecting rod away from the connecting plate.

[0008] Preferably, both sides of the extension frame are fixedly connected with protrusions, which are slidably connected to the inner wall of the support frame. The protrusions can guide the movement direction of the extension frame and, with the cooperation of the support frame, constrain the maximum movement distance of the extension frame.

[0009] Preferably, there are three support frames arranged in a circumferential array about the cylinder. The support frames, in cooperation with the assembly frame, can support the position of the extension frame to ensure the stability of the extension frame when it is supported by the support device.

[0010] Preferably, the anti-slip dial is located inside the support frame and contacts the upper surface of the extension frame. The anti-slip dial allows construction personnel to operate it, thereby facilitating the rotation of the lead screw to engage with the linkage nut and adjust the position of the extension frame.

[0011] Preferably, there are four connecting rods, which are arranged diagonally about the connecting plate. The connecting rods are slidably connected to the inner wall of the receiving cavity. The connecting plate and the fixed sleeve can be connected through the connection, so that the limiting spring can simultaneously constrain the position of the fixed sleeve while constraining the connecting plate.

[0012] Preferably, the limiting spring is sleeved on the surface of the connecting rod. The limiting spring can constrain the position of the connecting plate to ensure the stability of the connecting plate in the non-operational state, thereby keeping the connecting plate stationary relative to the support frame.

[0013] Preferably, the inner wall of the fixing sleeve is provided with a protrusion, which is adapted to the groove of the plum blossom shaft. The fixing sleeve is sleeved with the arc surface of the plum blossom shaft. Through the cooperation between the plum blossom shaft and the fixing sleeve, the connecting rod and the connecting plate can be assisted to lock the position of the support frame, and the support angle of the support frame can be adjusted at the same time.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, by setting up an assisting component, the support structure of the detection device can be stored, thereby reducing the problem that the support structure of the detection device is too large and easily interferes with the user's handling, and further improving the portability of the detection device.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a flowability detection device for tunnel grouting, including a cylinder 1 and a feeding cylinder 2. The feeding cylinder 2 is fixedly connected to the lower surface of the cylinder 1 and is connected to the interior of the cylinder 1. An assisting component 3 is provided on the outer circumference of the cylinder 1.

[0025] In this embodiment: the assisting component 3 includes a support unit 31, the support unit 31 includes an assembly frame 311, the assembly frame 311 is fixedly connected to the outer circumference of the cylinder 1, a support frame 312 is rotatably connected to the shaft of the assembly frame 311, a lead screw 313 is rotatably connected to the inner wall of the support frame 312, an anti-slip wheel 314 is fixedly connected to the arc surface of the lead screw 313, an extension frame 315 is slidably connected to the inner wall of the support frame 312, a linkage nut 316 is fixedly connected to the inner wall of the extension frame 315, the linkage nut 316 is threadedly connected to the surface of the lead screw 313, and a spherical rotating shaft 318 is fixedly connected to the end of the extension frame 315 away from the assembly frame 311, and a universal support foot 319 is installed on the arc surface of the spherical rotating shaft 318;

[0026] The assisting component 3 also includes a locking unit 32, which includes a plum blossom shaft 321. The plum blossom shaft 321 is fixedly connected to the side surface of the support frame 312. The side surface of the support frame 312 has a storage cavity 322. The support frame 312 is slidably connected to the inner wall of the storage cavity 322. The side surface of the connecting plate 323 is fixedly connected to a connecting rod 324. The connecting plate 323 is fixedly connected to a limit spring 325 on one side of the connecting rod 324. The side of the limit spring 325 away from the connecting plate 323 is fixedly connected to the inner wall of the storage cavity 322. The side of the connecting rod 324 away from the connecting plate 323 is fixedly connected to a fixing sleeve 326.

[0027] Specifically, both sides of the extension frame 315 are fixedly connected with protrusions 317. The protrusions 317 are slidably connected to the inner wall of the support frame 312. The protrusions 317 can guide the movement direction of the extension frame 315, and with the cooperation of the support frame 312, the maximum movement distance of the extension frame 315 can be constrained.

[0028] Specifically, there are three support frames 312, which are arranged in a circular array about the cylinder 1.

[0029] In this embodiment, the support frame 312 and the assembly frame 311 cooperate to support the position of the extension frame 315, so as to ensure the stability of the extension frame 315 when it is supported by the support device.

[0030] Specifically, the anti-slip dial 314 is located inside the support frame 312. The anti-slip dial 314 is in contact with the upper surface of the extension frame 315. The anti-slip dial 314 allows the construction personnel to operate it, thereby facilitating the construction personnel to rotate the lead screw 313 so that the lead screw 313 rotates and engages with the linkage nut 316, thereby adjusting the position of the extension frame 315.

[0031] In this embodiment, there are four connecting rods 324, which are arranged diagonally about the connecting plate 323, and the connecting rods 324 are slidably connected to the inner wall of the storage cavity 322.

[0032] In this embodiment, the connecting plate 323 and the fixing sleeve 326 can be connected by a connection, so that the limiting spring 325 can simultaneously constrain the position of the fixing sleeve 326 while constraining the connecting plate 323.

[0033] Specifically, the limiting spring 325 is sleeved on the surface of the connecting rod 324. The limiting spring 325 can constrain the position of the connecting plate 323 to ensure the stability of the connecting plate 323 in the non-operational state, so that the connecting plate 323 is stationary relative to the support frame 312.

[0034] Specifically, the inner wall of the fixing sleeve 326 is provided with a protrusion, which is adapted to the groove of the plum blossom shaft 321, and the fixing sleeve 326 is sleeved with the arc surface of the plum blossom shaft 321.

[0035] In this embodiment: the cooperation between the plum blossom shaft 321 and the fixing sleeve 326 can help the connecting rod 324 and the connecting plate 323 to lock the position of the support frame 312, and at the same time, the support angle of the support frame 312 can be adjusted.

[0036] Working principle: When testing the mortar flowability, the unfolded support structure is placed on the ground, and mortar is poured into cylinder 1 and discharge cylinder 2. Guided by discharge cylinder 2, the mortar flows downwards. During this flow, the operator can time the process. When the mortar has completely flowed out of the device, the flowability can be measured. After testing, when the device needs to be stored, the anti-slip wheel 314 is turned counterclockwise. The anti-slip wheel 314 rotates the screw 313, which engages with the linkage nut 316. Under the action of the screw 313, the linkage nut 316 pushes the extension frame 315 towards the assembly frame 311. The extension frame 315 gradually slides into the support frame 312. When the extension frame 315 is fully retracted into the support frame 312, the fixing sleeve 326 is pulled. The fixing sleeve 326 is pulled away from the plum blossom shaft 321 and loses its locking effect on the support frame 312. Simultaneously, the fixing sleeve 326 engages with the connecting rod 32... 4. Pull the connecting plate 323. The connecting plate 323 compresses the limiting spring 325. The limiting spring 325 is compressed and deformed. When the support frame 312 is unlocked, rotate the support frame 312 in the direction of the downward material cylinder 2. When the support frame 312 is rotated to the vertical position, release the fixing sleeve 326. The connecting rod 324 loses the tension applied to the connecting plate 323. The connecting plate 323 loses the pressure applied to the limiting spring 325. The limiting spring 325 loses the pressure and rebounds, pushing the connecting plate 323 to reset. The connecting plate 323, together with the connecting rod 324, pulls the fixing sleeve 326 to reset. The fixing sleeve 326 is re-fitted onto the plum blossom shaft 321 and the position of the support frame 312 is re-locked. By setting the assisting component 3, the support structure of the detection device can be stored, thereby reducing the problem that the support structure of the detection device is large and easily interferes with the user's handling, and further improving the portability of the detection device.
