Description

TECHNICAL FIELD

[0001] The utility model relates to monitoring device technical field, especially tunnel surrounding rock stability monitoring device. BACKGROUND

[0002] Rock deformation refers to the total of the rheological, creep, creep, displacement, settlement and floor drum of surrounding rock. Especially in the tunnel construction process, the deformation measurement of the loose circle of surrounding rock is a must-measure item. Whether the deformation characteristics of the tunnel structure can be accurately and timely provided has a decisive significance for the stability of the initial support of the tunnel and the construction time of the secondary lining, and is also an important means to ensure the safe construction and operation of the tunnel. Since multiple detection sections are arranged in the tunnel and multiple sensing systems are arranged on the lining surface of each detection section, when the sensing device needs to be repaired or fails, it is necessary to find each detection section and disassemble the screws or pipeline structures of the fixed sensing device arranged on each section, resulting in a relatively complex disassembly process of the sensing device.

[0003] A tunnel surrounding rock deformation monitoring device is disclosed in Chinese Utility Model Patent No. CN218972352U, which relates to the technical field of monitoring equipment. The tunnel surrounding rock deformation monitoring device includes a device body, which includes a mounting frame, a mounting plate, a deformation monitoring device, a protection unit, and a clamping groove. The mounting frame is fixed at the target position in the tunnel through the mounting plate and mounting pieces. The deformation monitoring device is placed in the mounting frame, and the protection unit is connected with the mounting frame through the clamping groove. Therefore, when the deformation monitoring device fails or needs to be repaired, the deformation monitoring device can be removed by opening the protection unit, avoiding the process of disassembling screws or pipeline structures. At the same time, since the deformation monitoring device is placed in a closed space, the gravel in the tunnel is prevented from directly hitting the deformation monitoring device, thereby maintaining the monitoring effect and service life of the deformation monitoring device.

[0004] According to the related technology in the above, the inventors believe that the following defects exist: In order to reduce the difficulty of the staff in repairing the sensing device, the above device exposes the deformation monitoring device in the line of sight by removing the protection unit, and removes the deformation monitoring device by sliding it upwards. In actual use, since the top of the tunnel surrounding rock is mostly arched, when the staff installs the deformation monitoring device at the upper end of the tunnel surrounding rock, the tunnel surrounding rock is easy to interfere with the movement of the deformation monitoring device, and the difficulty of removing the deformation monitoring device is still high, and the scope of application is poor. UTILITY MODEL CONTENTS

[0005] In order to solve the above problems, the utility model provides a tunnel surrounding rock stability monitoring device.

[0006] The above technical purpose of the utility model is realized through the following technical scheme: a tunnel surrounding rock stability monitoring device, including installation frame body, installation plate set on installation frame body, installation piece set on installation plate, protection unit slidingly set on installation frame body and deformation monitoring equipment set in installation frame body, two fixed plates are symmetrically slidingly set in installation frame body, the side wall of two fixed plates away from each other all are fixed with clamping spring, the other end of clamping spring is fixed on the inner wall of installation frame body, the side wall of two fixed plates close to each other all are set with sliding slot, two sliding slots all are slidingly set with sliding rod, two sliding rods are fixed with the two side walls of deformation monitoring equipment respectively.

[0007] When the staff needs to overhaul the deformation monitoring equipment, the staff needs to separate the deformation monitoring equipment from the installation frame body, at this time, the staff needs to remove the fixing screw on the protection unit, and slides the protection unit upwards, so that the protection unit and the installation frame body are separated, and then the deformation monitoring equipment is exposed in the line of sight. Further, the staff only needs to pull the deformation monitoring equipment, so that the sliding rod gradually separates from the sliding slot, thereby taking out the deformation monitoring equipment. In this process, the deformation monitoring equipment always moves away from the surrounding rock side wall, thereby reducing the probability of interference caused by the movement of the surrounding rock on the deformation monitoring equipment.

[0008] Further, the side wall of the sliding rod is provided with a limiting slot, the limiting slot is slidingly provided with a limiting rod, the inner wall of the limiting slot is provided with a rotating slot, the rotating slot is slidingly provided with a rotating rod, the side wall of the limiting rod close to the rotating rod is provided with a placing slot, and the inner wall of the placing slot close to the opening side of the limiting slot and the edge where the side wall of the limiting rod close to the rotating rod intersects are provided with an inclined surface.

[0009] Further, the inner wall of the sliding slot is provided with a limiting hole matched with the limiting rod.

[0010] By adopting the above technical scheme, when the staff needs to install the deformation monitoring equipment, the staff needs to connect the sliding rod and the sliding slot, so that the limiting slot gradually approaches and finally faces the limiting hole. At this time, the staff only needs to slide the rotating rod, so that the rotating rod abuts against the inclined surface, so that the limiting rod is connected with the limiting hole under the action of the rotating rod, thereby blocking the sliding rod with the limiting rod, so that the sliding rod remains stable, and the deformation monitoring equipment remains stable.

[0011] Further, the side wall of the limiting rod away from the opening side of the limiting slot is fixed with a tension spring, and the other end of the tension spring is fixed on the inner wall of the limiting slot.

[0012] By adopting the above technical scheme, when the limiting rod and the rotating rod are separated from each other, the limiting rod is automatically reset under the action of the tension spring, and then the limiting rod is automatically separated from the limiting hole, without the need for the staff to actively slide the limiting rod, thereby reducing the operation difficulty of the staff.

[0013] Further, the side wall of the rotating rod is provided with external threads, and the inner wall of the rotating groove is provided with internal threads matched with the external threads.

[0014] By adopting the above technical scheme, when the staff needs to move the rotating rod, the staff only needs to rotate the rotating rod, so that the rotating rod moves towards the limiting rod under the joint action of the external threads and the internal threads.

[0015] Further, the side wall of the rotating rod is fixed with a silica gel block.

[0016] By adopting the above technical scheme, the silica gel block reduces the probability of damage to the inclined surface, thereby improving the use experience of the staff.

[0017] Further, the inner wall of the installation groove is provided with a containing groove for passing through the rotating rod.

[0018] By adopting the above technical scheme, when the rotating rod passes over the inclined surface, one end of the rotating rod is connected with the containing groove, thereby improving the stability of the limiting rod.

[0019] Further, the end of the rotating rod is fixed with a handle for reducing the difficulty of rotating the rotating rod for the staff.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1、In the application, when the staff needs to overhaul the deformation monitoring equipment, the staff needs to separate the deformation monitoring equipment from the mounting frame, at this time, the staff needs to remove the fixing screws on the protective unit, and slide the protective unit upwards, so that the protective unit is separated from the mounting frame, and then the deformation monitoring equipment is exposed in the line of sight. Further, the staff only needs to pull the deformation monitoring equipment, so that the sliding rod is gradually separated from the sliding groove, thereby taking out the deformation monitoring equipment. In this process, the deformation monitoring equipment always moves away from the surrounding rock side wall, thereby reducing the probability of interference of the surrounding rock on the movement of the deformation monitoring equipment;

[0022] 2、The staff needs to install the deformation monitoring device in the application, the staff needs to connect the sliding rod and the sliding groove with each other, that is, the limiting groove gradually approaches and finally faces the limiting hole. At this time, the staff only needs to slide the rotating rod, so that the rotating rod abuts against the inclined surface, so that the limiting rod is connected with the limiting hole under the action of the rotating rod, and then the limiting rod blocks the sliding rod, so that the sliding rod remains stable, and then the deformation monitoring device remains stable;

[0023] 3、When the limiting rod and the rotating rod are separated from each other, the limiting rod is automatically reset under the action of the tension spring, so that the limiting rod is automatically separated from the limiting hole without the staff sliding the limiting rod actively, thereby reducing the operation difficulty of the staff.
