Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inclinometer, and particularly to a monitoring inclinometer pipe mouth fixing device. BACKGROUND

[0002] The inclinometer is an instrument for measuring the top angle and azimuth angle of engineering structures such as drill holes, foundation pits, foundation bases, walls and dam bodies, and is also an in-situ monitoring instrument for obtaining horizontal displacement by measuring the inclination angle of a drill hole.

[0003] At present, the inclinometer mainly comprises a measurement guide pipe, an inclinometer probe, a control cable and a reading instrument. The measurement guide pipe is pre-buried in the soil, and a pipe groove is formed in the measurement guide pipe to form a measurement channel. The control cable is fixedly connected with a clamping point ring on the outer periphery, and a plurality of clamping point rings are uniformly arranged along the extension direction of the control cable, and the adjacent clamping point rings are arranged at intervals of 50 cm. One end of the control cable is connected to the inclinometer probe, and the other end is connected to the reading instrument. During monitoring, the inclinometer probe is first put into the ground along the measurement channel, then the control cable is pulled up, until the clamping point ring is located at the pipe mouth position, and the reading is taken every 50 cm through the reading instrument, and finally the measurement readings are collected and analyzed.

[0004] However, when the inclinometer probe is pulled up by the control cable, in order to make the clamping point ring play the role of the clamping point, the outer skin of the control cable is usually in sliding contact with the pipe wall at the pipe mouth of the measurement guide pipe. After long-term use, the outer skin of the control cable is prone to friction damage. Content of the utility model

[0005] In order to reduce the friction damage of the cable outer skin, the present application provides a monitoring inclinometer pipe mouth fixing device.

[0006] The present application provides a monitoring inclinometer pipe mouth fixing device, which adopts the following technical scheme:

[0007] A monitoring inclinometer pipe mouth fixing device comprises a mounting ring, and a mounting groove is formed in the top of the mounting ring;

[0008] A mounting strip is arranged on the opposite vertical groove walls of the mounting groove;

[0009] A wire wheel is rotatably connected between the mounting strips, and the wire wheel is located directly above the pipe mouth of the wire wheel;

[0010] Mounting blocks are symmetrically arranged and slidably arranged on the opposite sides of the mounting strips;

[0011] A clamping point rope is arranged between the mounting blocks, and the mounting strip is provided with an elastic driving member. When the clamping point rope is relaxed, the elastic driving member drives the mounting blocks to slide to the side of the clamping point rope abutting against the cable away from the wire wheel;

[0012] A control member is arranged on the mounting strip, and when the clamping ring pulls the clamping rope, the control member controls the mounting block to slide away from the wire wheel.

[0013] By using the above technical scheme, when measuring, the control cable is pulled to make the inclinometer probe continuously slide out of the measuring guide pipe until the clamping ring pulls the clamping rope, at which time the reading instrument can be used for reading. The control cable is slidably connected to the wire wheel, which is conducive to reducing the friction damage of the cable outer skin. During the process that the clamping ring pulls the clamping rope, the control member pulls the mounting block to make the clamping rope away from the control cable, so that the clamping ring can pass through the clamping rope. After the reading is completed, the control cable is continuously pulled according to the same steps until the next clamping ring pulls the clamping rope to continue reading, and so on, until the reading of the positions of all clamping rings is completed, and finally the reading results are collected and analyzed.

When the clamping ring pulls the clamping rope, the control rope pulls the mounting block away from the wire wheel, and at the same time the mounting block drives the clamping rope to move away from the clamping ring, thereby releasing the cable. This design makes the restriction and release of the cable more flexible and controllable, and improves the practicability and convenience of the device.

[0021] Optionally, the side wall of the mounting block is provided with a limiting block, and the groove wall of the sliding groove is provided with a limiting groove for the sliding of the limiting block close to or away from the wire wheel.

[0022] By adopting the technical scheme, the limiting block is arranged on the side wall of the mounting block, and the limiting groove is arranged on the slot wall, so that the sliding range of the mounting block is limited, and the possibility of the mounting block being separated from the mounting strip is reduced.

[0023] Optionally, the elastic driving member is a driving spring, the driving spring is arranged in the slot, and the driving spring drives the mounting block to slide towards the wire wheel.

[0024] By adopting the technical scheme, the driving spring is arranged in the slot, and the driving mounting block slides towards the wire wheel, so that the clamping point rope is limited to the cable. When the cable needs to be released, the control member operates the mounting block to slide, the elastic force of the spring is overcome, and the release of the cable is realized. This design makes the fixing of the cable more firm and reliable.

[0030] Optionally, the elastic power member is a power torsion spring, and the mounting strip is provided with a rotating shaft for rotating connection of the mounting strip.

[0031] The power torsion spring is sleeved on the outer circumferential side of the rotating shaft, one end of the power torsion spring is clamped to the mounting ring, and the other end abuts against the side of the mounting strip away from the limiting block.

DETAILED DESCRIPTION

[0048] The following will be described in detail below with reference to the accompanying drawings Figures 1-4 The present application is further described in detail.

[0049] The embodiment of the present application discloses a kind of monitoring inclinometer pipe orifice fixing device. Refer to Figure 1 With Figure 2 , fixing device includes mounting ring 1, mounting ring 1 includes first half ring 11, second half ring 12 and connecting bolt 13, first half ring 11 and second half ring 12 are respectively circular arc plate structure, and the end of first half ring 11 and second half ring 12 is hingedly connected. The opposite side of first half ring 11 and second half ring 12 is fixedly connected with connecting plate 14, and connecting bolt 13 is arranged in one of connecting plate 14 and is threadedly connected with the other connecting plate 14. When installing, first half ring 11 and second half ring 12 are clamped in the position of surveying guide pipe orifice, and by being threadedly connected with the other connecting plate 14 on connecting bolt 13, first half ring 11 and second half ring 12 are matched with each other, and are clamped and fixed in the position of surveying guide pipe orifice.

[0050] The inner circumferential wall of first half ring 11 and second half ring 12 is fixedly connected with rubber layer 17 respectively, and rubber layer 17 is in abutment with the outer circumferential wall of surveying guide pipe, which is conducive to improving the connection stability between first half ring 11, second half ring 12 and surveying guide pipe.

[0051] Refer to Figure 3 With Figure 4 , fixing device further includes mounting strip 2 and wire wheel 3, and the top of first half ring 11 is provided with mounting groove 15, and the vertical side wall of the opposite side of mounting groove 15 is fixedly connected with rotating shaft 26.

[0052] Wire wheel 3 is rotationally connected between two opposite mounting strips 2, and cable slot 31 is formed in the outer circumferential wall of the middle part of wire wheel 3 and extends in the circumferential direction. When using, the cable is slid in the cable, and the position of the cable is limited by the groove wall of cable slot 31, so that the cable can be pulled conveniently.

[0053] The installation strip 2 is provided with an elastic driving element, which is a power torsion spring 25 sleeved on the outer circumferential side of the rotating shaft 26. One end of the power torsion spring 25 is clamped and fixed on the installation ring 1, and the other end abuts against the position of the installation strip 2 away from the central axis of the installation ring 1. When the installation strip 2 is turned away from the central axis of the installation ring 1, the power torsion spring 25 is in an elastic compression state.

[0054] Referring to Figure 2 With Figure 3 , the installation ring 1 is fixedly connected with a limiting block 16 located on the side of the installation strip 2 close to the central axis of the installation ring 1. When the power torsion spring 25 is elastically released, the installation strip 2 is driven to turn towards the central axis of the installation ring 1 until the installation strip 2 abuts against the side of the limiting block 16 away from the central axis of the installation ring 1. At this time, the wire wheel 3 can move to the position close to the central axis of the installation ring 1, which is conducive to the cable being in a relatively vertical state, facilitating the up-down movement of the inclinometer probe. Moreover, when the inclinometer probe is put into or taken out of the measurement conduit, the installation strip 2 can be turned away from the central axis of the installation ring 1, reducing the possibility of the wire wheel 3 hindering the inclinometer probe.

[0055] Referring to Figure 3 With Figure 4 , the fixing device further comprises an installation block 4, a clamping point rope 5 and a control element. The opposite sides of the two installation strips 2 are respectively provided with a sliding groove 22 extending along the length direction of the installation strip 2. The installation block 4 corresponds to the installation strip 2 one by one and slides in the sliding groove 22. The side wall of the installation block 4 is fixedly connected with a limiting block, and the groove wall of the sliding groove 22 is provided with a limiting groove 24 extending along the length direction of the installation strip 2. The limiting block is slidingly connected in the limiting groove 24, so that the installation block 4 can approach or move away from the wire wheel 3 while limiting the installation block 4 from leaving the sliding groove 22.

[0056] The installation strip 2 is provided with an elastic driving element, which is a power torsion spring 25 sleeved on the outer circumferential side of the rotating shaft 26. One end of the power torsion spring 25 is clamped and fixed on the installation ring 1, and the other end abuts against the position of the installation strip 2 away from the central axis of the installation ring 1. When the installation strip 2 is turned away from the central axis of the installation ring 1, the power torsion spring 25 is in an elastic compression state.

[0057] The clamping point rope 5 is arranged between the two mounting blocks 4, the two side portions of the clamping point rope 5 are respectively slid through the two mounting blocks 4, and the diameter of the clamping point rope 5 is less than or equal to the wall thickness of the clamping point ring. The control member is a control rope 6, the control rope 6 is slid through the mounting block 4, and the control rope 6 and the mounting block 4 correspond to each other. The mounting strip 2 is provided with a connecting hole 23 in a reverse U-shaped structure, and the two side openings of the connecting hole 23 are respectively arranged on the side wall of the sliding groove 22 away from the wire wheel 3. One end of the control rope 6 is fixedly connected to the mounting block 4 away from the wire wheel 3, and the other end is fixedly connected to the end of the clamping point rope 5 after passing through the connecting hole 23, and the control rope 6 passes through the driving spring 21.

[0058] When the control cable is pulled upward, the end of the clamping point ring first abuts against the clamping point rope 5, and then the control cable continues to be pulled, the clamping point ring pulls the clamping point rope 5, at this time, the clamping point rope 5 buffers the control cable, so that the control cable is subjected to resistance when being pulled, and the operator is prompted to read the reading, without slowing down the pulling speed of the control cable, which is beneficial to shorten the time required in the monitoring process. At the same time, in the process that the clamping point ring pulls the clamping point rope 5, the clamping point rope 5 pulls the control rope 6 on both sides, at this time, the control rope 6 pulls the mounting block 4 to move away from the wire wheel 3, and the driving spring 21 is in a compressed state; when the mounting block 4 moves away from the wire wheel 3, the clamping point rope 5 moves away from the control cable, so that the clamping point ring can pass through the clamping point rope 5; and in the reading process, the clamping point rope 5 is located on the side of the clamping point ring close to the next adjacent clamping point ring, the clamping point rope 5 limits the clamping point ring from sliding into the measuring conduit, and the accuracy of the monitoring result is improved when the position of the clamping point ring changes.

[0059] The implementation principle of the monitoring device for the pipe opening fixing device of the inclinometer is as follows:

[0060] Before measurement, the mounting ring 1 is installed at the position of the pipe opening of the measuring conduit, then the control cable is passed between the clamping point rope 5 and the wire wheel 3 and is connected with the inclinometer probe and the reading instrument respectively, then the mounting strip 2 is turned over, so that the wire wheel 3 is away from the central axis of the mounting ring 1, and then the inclinometer probe is put into the measuring conduit.

[0061] During measurement, the control cable is pulled, so that the inclinometer probe continuously slides out of the measuring conduit, until the clamping point ring pulls the clamping point rope 5, and then the control cable is stopped, at this time, the reading instrument can be used for reading. In the process that the clamping point ring pulls the clamping point rope 5, the control rope 6 pulls the mounting block 4, so that the clamping point rope 5 is away from the control cable, and the clamping point ring is convenient to pass through the clamping point rope 5; after the reading is completed, the control cable is continuously pulled according to the same steps, until the next cable clamping point ring pulls the clamping point rope 5 to continue reading, and so on, until the readings of the positions of all clamping point rings are completed, and finally the reading results are collected and analyzed.

[0062] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
