Description

But observation platform of diversified connection installation of single-point

Technical Field

The utility model relates to the technical field of engineering construction measurement auxiliary devices, in particular to a tunnel construction measurement auxiliary device, and particularly relates to the technical field of fixed brackets of tunnel construction measurement instruments, in particular to an observation table capable of being installed in a single-point multi-azimuth connection mode.

Background

In the construction stage of the shield tunnel, in order to ensure that the shield machine tunnels along the design axis and forwards tunnels along with the shield machine, control wire points are required to be distributed in the tunnel, the control points are used for guiding the shield machine to tunnel forwards, the tunnel axis deviation of the tunneled forming tunnel is ensured to meet the design requirement, the requirement of subway operation structure limit is met, and the social and economic values of the tunnel are realized.

The matched shield guiding system on the shield machine needs to retest regularly and irregularly through the wire points distributed in the tunnel, retests the assembled tunnel segment by using the wire points, calculates the deviation condition with the design axis, grasps the quality of the formed tunnel, and carries out real-time deviation correction and adjustment in the subsequent construction process, thereby better controlling the construction quality of the formed tunnel. As the number of control points is gradually increased in the tunnel along with the forward tunneling of the shield tunneling machine, the construction is ensured to be smoothly and continuously carried out; a control point is generally distributed in the tunnel at intervals of about 60-120 m, and the control point is required to be added to meet construction requirements along with the conditions of tunnel construction requirements or curve construction and the like.

The technology of the utility model is formed based on the improvement of a first generation observation platform developed by the inventor, and the first generation observation platform technology is also the Chinese utility model patent closest to the prior art of the utility model and can be referred to by publication No. CN211401264U, the technology adopts two-point connection control, and through field product use and long-term verification, the applicant finds that the product adopting the two-point connection has limitations, namely some special points possibly exist, tunnel segments corresponding to ideal positions where the monitoring measuring points need to be installed in the shield tunnel do not have conditions conforming to the two-point installation, and the limitations exist. In order to solve the problem, the theoretical optimal point location installation is abandoned, and the next choice of duct piece installation which can be installed is obtained, but the yielding has yielding to the convenience and the accuracy in measurement or monitoring. Meanwhile, the applicant also discovers that a small amount of bracket angles change due to installation by adopting a mode of adjusting the strip-shaped holes through a large amount of practical use products, and the fastening bolts in the strip-shaped holes cannot always support the observation table to keep absolute level, but can generate tiny angle changes, so that the levelness of the observation table under the measurement equipment is inevitably corrected in the measurement or monitoring process, thereby increasing measurement errors and possibly causing measurement quality accidents. For the reasons and problems described above, the applicant has developed a new generation of single point connection mounted observatory for replacing the existing observatory.

Disclosure of utility model

In order to solve the problem of limitation of mounting positions in the prior art by adopting two-point mounting, the application provides an observation table capable of being mounted in a single-point and multi-azimuth manner, which can realize single-point mounting, can realize effective fixed mounting of the observation table without two-point connection, and can completely cover the existing observation table in other functions, and can further solve one of the following technical problems:

1. The problem that the original observation table can only be connected with a reserved hole at the installation position of a tunnel segment design bolt and has a limited connection point can be solved; besides the connection of the reserved holes, the utility model can also be installed in the reserved grooves on the tunnel segment through the T-shaped bolts, so that the installable point positions and positions are further increased.

2. The structure adopted by the utility model can be flexibly arranged on the left side, the right side, the upper side and the lower side according to actual scenes, is not limited by the installation position and the angle of the duct piece, meets the measurement requirement to the greatest extent, and greatly improves the practicability of the observation platform.

3. The utility model adopts the strip-shaped hole with the groove, effectively solves the problem that the angle of the observation platform changes due to the locking failure of the fastener, so that the observation platform is required to be fastened again, and then the wire in the tunnel is measured again, thereby generating the risk that the measured data changes to cause distortion of the measured data in the earlier stage and increasing the workload of measurement. Therefore, the equipment can be installed for a long time for use, and real once and once for all can be realized.

In order to achieve the above purpose, the technical scheme adopted by the application is as follows:

The utility model provides an observation platform that can single-point diversified connection installs, includes coupling mechanism, supporting mechanism, mounting panel and bracing mechanism, supporting mechanism will through coupling mechanism supporting mechanism fixed mounting is on the tunnel segment, mounting panel one end with supporting mechanism rotates to be connected and through setting up between mounting panel and supporting mechanism bracing mechanism is fixed. Function and working principle between the mechanisms:

The connecting mechanism is used for connecting the whole observation table with the tunnel segment together, so that the observation table is firmly fixed on the inner wall of the tunnel segment, the supporting mechanism mainly plays a supporting role, and the connecting mechanism, the mounting plate and the diagonal bracing mechanism are connected to form an integral structure, a simple plate-shaped structure is usually adopted, of course, the supporting mechanism can also adopt other non-plate-shaped structures or structures formed by splicing strips or rods as long as the supporting and connecting roles are met. The function of the mounting plate is to be used for installing measuring equipment, such as total powerstation, etc., under the installation and use state, the mounting plate is usually kept absolute level or relative level's position under the supporting action of bracing mechanism, and the optimum position of mounting plate theory is absolute level, but because measuring equipment, such as total powerstation is from taking leveling structure, and in actual measuring work, measuring equipment still can install a base that has leveling function in the past, therefore, the mounting plate only needs relative level, even is in the visual level state and is enough to satisfy the demand, because the levelness can be through the level adjustment of follow-up adjustable base and measuring equipment from taking leveling with the realization equipment. The function of the diagonal bracing mechanism is to facilitate adjustment of levelness of the mounting plate, and meanwhile, when the mounting plate is adjusted to a relatively horizontal position, the relative position and the angular relation between the mounting plate and the supporting mechanism are fixed.

In order to achieve the convenience of installation of the observation platform, namely, single-point installation and fixation are adopted, and meanwhile, stability after installation of the observation platform is achieved, preferably, the connecting mechanism comprises a connecting plate with one end hinged with the supporting mechanism or rotationally connected with the supporting mechanism, a first installation hole for installing a fastener to be connected with a duct piece is formed in the connecting plate, and a reverse jacking structure for adjusting an angle between the connecting plate and the supporting mechanism is fixedly arranged on the connecting plate. The connecting plate can be fixedly connected with the duct piece through the fastener, so that the connecting plate can be fixed on the duct piece, but at the moment, the supporting mechanism is still in a state of being capable of changing an angle relative to the duct piece in a certain range because the supporting mechanism is hinged or rotationally connected with the connecting plate, so that the meaning of the anti-jacking structure is particularly important for limiting and fixing the position of the supporting mechanism, and the anti-jacking structure is one of key utility model points for ensuring the stability of the observation table by adopting a single-point fixing mode. The anti-top structure can support the supporting mechanism to one side close to the duct piece until the supporting mechanism is firmly attached to the duct piece to achieve the purpose of fixation.

In order to ensure that the supporting mechanism is stable, the supporting mechanism is convenient to install, adjust and fix on site as much as possible, preferably, the anti-top structure comprises an anti-top formed by bending towards the plane direction of the supporting mechanism, and at least one first anti-top screw penetrating through the anti-top and contacting with the surface of the supporting mechanism to support the supporting mechanism against the tunnel segment is arranged on the anti-top. During actual installation, only the first anti-jacking screw is required to be screwed up, and the supporting mechanism is firmly abutted against the duct piece. It is worth to say that the more tightly the first anti-top screw is screwed, the greater the supporting force between the supporting mechanism and the duct piece is, the more stable.

In order to meet different application scenes, the installation and fixation can be realized at different positions and angles of the duct piece, and preferably, the connecting mechanism is alternatively hinged or rotationally connected with the upper end, the lower end, the left side or the right side of the supporting mechanism.

In order to further enhance the stability of the supporting mechanism, it is preferable that at least one second anti-jacking screw for limiting the relative position of the supporting mechanism and the tunnel segment is arranged on the opposite side of the connecting mechanism on the supporting mechanism. According to the lever principle, although under the action of the anti-jacking structure, the supporting mechanism can be firmly fixed on the duct piece; according to the lever principle, the acting force arm of the anti-top structure is the distance between the axial direction of the first anti-top screw rod and the axis where the connecting mechanism is hinged with the supporting mechanism, and because the position of the anti-top structure and the position where the connecting mechanism is hinged with the supporting mechanism or rotationally connected with the supporting mechanism are positioned at the same end, the force of the anti-top structure for fixing the supporting mechanism on the hanging piece is relatively large, which puts forward higher requirements for field installation personnel. That is, if the installer operating in the field does not ensure sufficient torque for the first counter-top screw, then poor stability of the support mechanism may occur. To avoid this problem, it can be achieved by a second anti-jackscrew, which has a longer moment arm than the first anti-jackscrew, since its position is on the opposite side of the connection mechanism, which is easier to adjust.

For better realization observation platform's installation, improve the practicality of observation platform, can accomplish the installation in the section of jurisdiction reservation recess, preferably, connection structure is including setting up the second mounting hole on the supporting mechanism, and run through the setting is in the second mounting hole is used for connecting at least one first connecting piece of supporting mechanism and tunnel section of jurisdiction.

Still further preferably, the second mounting hole is at least one bar-shaped hole or a plurality of through holes arranged at intervals along the length direction of the supporting mechanism, and the first connecting piece is a T-shaped bolt.

For better supporting the mounting plate, keep the stability of mounting plate, can compromise the mounting plate simultaneously and need adjust different angles in order to reach preferred horizontal position again, preferably, bracing mechanism includes both ends respectively with first diagonal bracing board and the second diagonal bracing board of supporting mechanism and mounting plate articulated or rotation connection, be provided with the bar hole on first diagonal bracing board and/or the second diagonal bracing board, install at least one in the bar hole be used for with first diagonal bracing board and second diagonal bracing board run through and fix the third connecting piece of relative position.

In order to avoid the problem that the horizontal state of the mounting plate is damaged due to the expansion and contraction of the diagonal bracing mechanism caused by external force after the mounting is completed, and thus the distortion of the measured data is caused, it is preferable that a plurality of grooves for accommodating and restricting the movement of the third connecting member are formed in the inner side wall of at least one side of the bar-shaped hole.

Still further preferably, the mounting plate is provided with a connecting hole or a second connecting piece for connecting the measuring instrument, the supporting mechanism adopts a plate structure, and screw holes for mounting the second anti-top screw are arranged at the positions, close to four corners, of the supporting mechanism.

The beneficial effects are that:

1. The utility model can realize single-point installation, and simultaneously solves the problem that the original observation table can only be connected with a preformed hole (hand hole) of the installation position of a tunnel segment design bolt, and has a limited connection point; besides the connection of the reserved holes, the utility model can also be installed in the reserved grooves on the tunnel segment through the T-shaped bolts, so that the mountable point positions are further increased.

2. The structure adopted by the utility model can be flexibly arranged on the left side, the right side, the upper side and the lower side according to actual scenes, is not limited by the installation position and the angle of the duct piece, meets the measurement requirement to the greatest extent, and greatly improves the practicability of the observation platform.

3. The utility model adopts the strip-shaped hole with the groove, effectively solves the problem that the angle of the observation platform changes due to the locking failure of the fastener, so that the observation platform is required to be fastened again, and then the wire in the tunnel is measured again, thereby generating the risk that the measured data changes to cause distortion of the measured data in the earlier stage and increasing the workload of measurement. Therefore, the equipment can be installed for a long time for use, and real once and once for all can be realized.

Example 1:

Referring to fig. 1-2 of the accompanying drawings, the observation stand capable of being installed in a single-point multi-azimuth connection provided by the embodiment comprises a connecting mechanism 1, a supporting mechanism 2, a mounting plate 3 and a diagonal bracing mechanism 4, wherein the supporting mechanism 2 is fixedly installed on a tunnel segment through the connecting mechanism 1, one end of the mounting plate 3 is rotationally connected with the supporting mechanism 2 and is fixed through the diagonal bracing mechanism 4 arranged between the mounting plate 3 and the supporting mechanism 2, the connecting mechanism 1 comprises a connecting plate 11, one end of the connecting plate 11 is hinged or rotationally connected with the supporting mechanism 2, a first mounting hole 12 for mounting a fastener to be connected with the segment is formed in the connecting plate 11, and a counter-top structure 13 fixedly arranged on the connecting plate 11 and used for adjusting an angle between the connecting plate 11 and the supporting mechanism 2. Function and working principle of the mechanism:

The connection mechanism 1 is used for connecting the whole observation platform with the tunnel segment, so that the observation platform is firmly fixed on the inner wall of the tunnel segment, the supporting mechanism 2 mainly plays a supporting role, and the connection mechanism 1, the mounting plate 3 and the diagonal bracing mechanism 4 are connected to form an integral structure, and a simple plate-shaped structure is usually adopted, however, the supporting mechanism 2 can also adopt other non-plate-shaped structures or structures formed by splicing strips or rods with holes as long as the supporting and connecting functions are met. The mounting plate 3 is used for mounting measuring equipment, such as a total station, etc., in the mounting and using state, the mounting plate 3 is usually kept in an absolute level or a relative level under the supporting action of the diagonal bracing mechanism 4, and the theoretical optimal position of the mounting plate 3 is the absolute level, but because the measuring equipment, such as the total station, has a leveling structure, the measuring equipment is further provided with a base with a leveling function, in the actual measuring work, the mounting plate 3 only needs to be relatively level, even in a visual level state, so that the requirement is satisfied, because the levelness can be adjusted through the subsequent leveling base and the leveling of the measuring equipment. The function of the diagonal bracing mechanism 4 is to facilitate adjustment of the levelness of the mounting plate 3, and at the same time, the relative position and the angular relationship between the mounting plate 3 and the supporting mechanism 2 are fixed when the mounting plate 3 is adjusted to a relative horizontal position. In this embodiment, the connecting plate 11 can be firmly connected with the duct piece through the fastening piece, so as to be fixed on the duct piece, but at this time, because the supporting mechanism 2 is hinged or rotationally connected with the connecting plate 11, the supporting mechanism 2 is still in a state that can change angle relative to the duct piece within a certain range, so that the meaning of the anti-jacking structure 13 is particularly important for limiting and fixing the position of the supporting mechanism 2, which is one of the key utility model points of the utility model that the stability of the observation table can be ensured by adopting a single-point fixing mode. Referring to fig. 1 of the specification, the anti-top structure 13 can support the supporting mechanism 2 to the side close to the duct piece until the supporting mechanism 2 is firmly attached to the duct piece to achieve the purpose of fixing.

In order to ensure that the supporting mechanism 2 is stable and convenient to install, adjust and fix on site as much as possible, in this embodiment, the anti-top structure 13 includes an anti-top portion formed by bending towards the plane direction of the supporting mechanism 2, and at least one first anti-top screw 14 penetrating the anti-top portion and contacting the surface of the supporting mechanism 2 to support the supporting mechanism 2 against the tunnel segment is disposed on the anti-top portion. In actual installation, only the first anti-jacking screw 14 is required to be screwed down, and the supporting mechanism 2 is firmly abutted against the duct piece. It should be noted that the more tightly the first anti-jacking screw 14 is screwed, the more stable the abutment force between the support mechanism 2 and the segment is. It should be noted that, in the present embodiment, the plane direction of the supporting mechanism 2 refers to the direction of the whole structure of the supporting mechanism 2, for example, the supporting mechanism 2 is a plate-shaped structure, and the plane of the supporting mechanism 2 refers to the plane of the plate-shaped structure, if the supporting mechanism 2 is not a standard plane, the plane is determined by the general plane of the whole structure of the supporting mechanism 2, for example, a plane most representing the main structure of the supporting mechanism 2 or a plane of a connecting line of three points representative on the main structure of the supporting mechanism 2.

Example 2:

The difference between this embodiment and embodiment 1 is that the relative orientations of the connection mechanism 1 and the support mechanism 2 are different, so that in order to meet different application scenarios, the installation and fixation can be realized at different positions and angles of the duct piece, in this embodiment, the connection mechanism 1 is alternatively hinged or rotationally connected with the upper end, the lower end, the left side or the right side of the support mechanism 2. The preformed hole structures in different directions that set up different directions can be provided according to the section of jurisdiction for the observation platform can be installed according to the preformed hole structures of any direction that the section of jurisdiction provided, avoids the direction of coupling mechanism 1 of observation platform inconsistent with section of jurisdiction preformed hole direction and unable installation, can only change and can install the position and lead to the problem that the testing point position is not the best point position to appear nearby. For example, when the segment at the optimal observation/measurement point has only left reserved holes, if the observation platform is in a fixed direction, such as an upper connection direction, only the reserved holes connected nearby can be found for installation. The coupling mechanism 1 of observation platform that this embodiment provided has multiple installation direction, can satisfy the section of jurisdiction reservation connecting hole of any direction, has promoted the practicality of installation greatly. It should be noted that, in the present application, the connection of the connection mechanism 1 to the support mechanism 2 refers to the hinging or rotating connection of the connection mechanism 1 to the upper end, the lower end, the left side or the right side of the support mechanism 2 in the actual use state, but in order to achieve this convenient function, one or more directions of the upper end, the lower end, the left side or the right side of the support mechanism 2 may be selected to be set in advance in the member of the connection mechanism 1 to establish the connection relationship, and when the connection is required to be performed in a certain direction, the connection mechanism may be installed directly on site without additional welding, which may be specifically shown in fig. 10.

Example 3:

In this embodiment, in order to further enhance the stability of the supporting mechanism 2 on the basis of embodiment 1 or embodiment 2, in this embodiment, at least one second anti-jacking screw 21 for defining the relative position of the supporting mechanism 2 and the tunnel segment is disposed on the opposite side of the supporting mechanism 2 to the connecting mechanism 1. Referring to fig. 1, according to the lever principle, the support mechanism 2 can be firmly fixed on the duct piece even though it is under the action of the anti-jacking structure 13; as known from the lever principle, the force arm of the anti-jacking structure 13 is the distance between the axial direction of the first anti-jacking screw 14 and the axis of the hinge connection mechanism 1 and the support mechanism 2, and because the position of the anti-jacking structure 13 and the position of the hinge connection or rotation connection of the connection mechanism 1 and the support mechanism 2 are located at the same end, the force of the anti-jacking structure 13 for fixing the support mechanism 2 on the hanging piece is relatively large, which puts higher demands on field installers. That is, if the installer operating in the field does not ensure sufficient torque for the first counter-top screw 14, it may occur that the support mechanism 2 is less stable than desired. To avoid this problem, this can be achieved by the second counter-top screw 21, which has a longer moment arm than the first counter-top screw 14, since the position of the second counter-top screw 21 is located on the opposite side of the connection 1, which is easier to adjust. In fig. 1 the connection 1 is located at the upper end of the support 2 and the second counter-top screw 21 is mounted on the opposite side of the connection 1 and is located at the lower end of the support 2 as shown. As another embodiment, referring to fig. 4 and 5, the connection structure 1 is shown on the left side of the support mechanism 2, and then the second anti-jacking screw 21 should be mounted on the right end of the support mechanism 2. Similarly, when the coupling mechanism 1 is in other orientations, the second counter-top screw 21 should also be located on the opposite side of the coupling mechanism 1. Of course, for convenience of practical selection, screw holes 211 for mounting the second anti-jacking screw 21 may be provided in all four directions of the supporting mechanism 2, as shown in fig. 10.

Example 4:

Referring to fig. 6-7, in order to better implement the installation of the observation stand, improve the practicality of the observation stand, and complete the installation in the gap between two adjacent tunnel segments, in this embodiment, the connection structure 1 includes a second installation hole 22 disposed on the support mechanism 2, and at least one first connection member 23 penetrating through the second installation hole 22 and used for connecting the support mechanism 2 and the tunnel segments. Still further preferably, the second mounting hole 22 is at least one bar-shaped hole or a plurality of through holes arranged at intervals along the length direction of the supporting mechanism, and the first connecting member 23 is a T-shaped bolt. During installation, the T-shaped bolt can penetrate through the strip-shaped hole or the through hole to form clamping connection with the duct piece, and then the T-shaped screw is fixed through the nut, so that the supporting mechanism 2 is fixed on the duct piece. Most preferably, a bar-shaped hole as shown in fig. 6, 7 and 8 can be adopted, so that the T-shaped bolt can slide up and down in the bar-shaped hole, thereby being convenient for adjusting the relative position of the supporting mechanism 2 and the duct piece and the fixing position of the T-shaped bolt. Of course, it is also possible to use a separate through hole provided on the supporting mechanism 2 for installing the T-shaped bolt, and in contrast, although both the two modes can achieve installation and fixation, in terms of installation convenience, the strip-shaped hole is more convenient for adjustment and preferably uses two or more T-shaped bolts up and down or left and right for fastening, so that the technical effect of fixation can be better.

Example 5:

In this embodiment, as shown in fig. 1 to 7, the diagonal bracing mechanism 4 includes a first diagonal bracing plate 42 and a second diagonal bracing plate 43, two ends of which are respectively hinged or rotationally connected with the supporting mechanism 2 and the mounting plate 3, and the first diagonal bracing plate 42 and/or the second diagonal bracing plate 43 are provided with a strip-shaped hole 45, and at least one third connecting piece 47 for penetrating and fixing the relative positions of the first diagonal bracing plate 42 and the second diagonal bracing plate 43 is installed in the strip-shaped hole 45. In this embodiment, the first diagonal brace 42 is hinged to the first connecting seat 41 fixedly provided on the support mechanism 2, and the second diagonal brace 43 is hinged to the second connecting seat 44 fixedly provided on the mounting plate 3.

In order to avoid the problem that the horizontal state of the mounting plate 3 is damaged due to the expansion and contraction of the diagonal bracing mechanism 4 caused by external force, etc. after the installation is completed, a plurality of grooves 46 for accommodating and restricting the movement of the third connecting member 47 are provided on the inner sidewall of at least one side of the bar-shaped hole 45 in this embodiment. As shown in fig. 3, the groove 46 is used for limiting the relative sliding of the first diagonal brace plate 42 and the second diagonal brace plate 43, and the limiting principle is that the groove 46 cooperates with the third connecting member 47 to form a structural limitation, so that the third connecting member 47 is abnormally loosened, and the first diagonal brace plate 42 and the second diagonal brace plate 43 cannot relatively displace as long as the third connecting member 47 is still in the groove 46. As shown in fig. 2, the grooves 46 are provided on both side walls of the bar-shaped holes 45 on the first and second diagonal plates 42 and 43, respectively, and this is not the only way to provide, but it is also possible to provide the grooves 46 on one side, for example, on the left side wall of the bar-shaped holes 45 of the first diagonal plate 42, and then corresponding grooves 46 are provided on the right side wall of the bar-shaped holes 45 of the second diagonal plate 43, so that the same limiting or restricting effect can be achieved. Naturally, if grooves 46 are provided on the side walls of the bar-shaped holes 45 on the first and second diagonal plates 42, 43 on the same side, the restriction effect can be achieved, and the relative displacement of the first and second diagonal plates 42, 43 or the relative displacement caused by insufficient friction force due to loosening of the third connecting piece 47 can be avoided.

Still further preferably, the mounting plate 3 is provided with a connection hole or a second connection piece 31 for connecting with a measuring instrument, and the supporting mechanism 2 adopts a plate structure, and screw holes 211 for mounting the second anti-top screw 21 are respectively arranged near four corners of the supporting mechanism 2.

Referring to fig. 8 and 9 of the drawings, a typical manner of articulation and/or rotational connection is shown. Referring to fig. 8, the connecting plate 11 is fixedly connected with a first sleeve 15, the supporting mechanism 2 is fixedly connected with a second sleeve 24 matched with the first sleeve 15, and the first sleeve 15 and the second sleeve 24 are fixedly connected in a hinged and/or rotary manner through a pin 16 penetrating through the first sleeve 15 and the second sleeve 24. Referring to fig. 9, in order to facilitate the layout and installation of the anti-top structure 13, another manner of hinging and/or rotating connection may be adopted, specifically, the connecting plate 11 is fixedly connected with a first sleeve 15, the supporting mechanism 2 is fixedly connected with two second sleeves 24 matched with the first sleeve 15, and the second sleeves are respectively located at two sides of the first sleeve 15, and are fixedly connected through the pin shaft 16.
