Description

TECHNICAL FIELD

[0001] The utility model belongs to the engineering construction technical field especially a kind of anchor cable hole video endoscope supporting device. BACKGROUND

[0002] In the field of engineering construction, slope is a common engineering form. As a deep support form, prestressed anchor cable has been widely used in slope protection of various projects, which is crucial to the permanent safety and stability of slope. According to the stress characteristics of prestressed anchor cable design, the quality of anchor cable anchoring section surrounding rock is crucial to the quality of anchor cable. According to the current standards and specifications such as "Technical Specification for Rock Anchor" (CECS22-2005), "Prestressed Anchoring Construction Specification for Water and Hydropower Engineering" (DL / T 5083-2019), the rock of anchor cable anchoring section is required to be complete and stable.

[0003] Currently, the conventional method for determining the integrity of the surrounding rock of the prestressed anchor cable hole anchoring section is to collect rock powder during drilling and determine whether there is drill sticking, drill dropping, hole collapse, etc. With the rapid development of miniature camera technology, the economy, efficiency and functionality of the equipment are continuously improving. The miniature camera can effectively solve the problem that the naked eye cannot reach the real appearance of the area, and provide more objective, real and accurate state. Especially based on the image processing system and recorder of industrial video endoscope, the inspection defects can be recorded, stored, processed and stored at any time, which can realize the functions of recording, storage, processing and guaranteeing the storage of camera data. The industrial endoscope detection technology is widely used in many industries. Based on the video endoscope inspection technology principle of industrial endoscope and pipeline endoscope, the anchor cable hole process provides more objective, real and accurate rock mass structure state, and intuitively and effectively finds and determines the type of slope deep rock mass structure defect. When drilling is difficult, after defect treatment and hole scanning, and after final hole, hole camera is carried out, and hole defect certification is formed and included in the anchor cable quality control evaluation table sequence, which is saved as permanent archive data.

[0004] The slope rock mass is mainly composed of dissolution breccia, thin layer of limestone and thin layer of dolomite. Anchor cables are mainly arranged in thin layer of limestone and dolomite area. The rock mass geological structure is complex. When using conventional rock powder surrounding rock determination method, although the rock powder blown by anchor cable drilling rig can be used to make construction, supervision and design personnel preliminarily judge the surrounding rock condition in hole, this method has obvious disadvantages. The determination cycle is long, which can greatly slow down the overall progress of anchor cable construction, and cannot meet the needs of efficient construction. Moreover, when facing complex geological conditions such as dissolution cavity and fracture developed in deep rock mass, this method can hardly provide accurate and effective determination basis.

[0005] The current slope prestressed anchor cable design inclination angle is generally between 10-20 degrees, the current is restricted by industrial pipeline endoscope camera size, small diameter, hole detection camera lens drag ground movement, resulting in hole camera view is not straight, the coverage of the shot is limited, and the lens is difficult, it is difficult to clearly, fully and completely record the real state of the surrounding rock around the hole, which brings many inconveniences to the surrounding rock determination work, the traditional endoscope lacks effective correction mechanism, and cannot keep stable angle in complex hole environment, because there is no special alignment component, the lens is easy to deviate from the predetermined angle due to collision or vibration during lowering, if the camera view is not straight, the shot picture will appear distortion phenomenon, which leads to unable to accurately reflect the real state of the surrounding rock in the hole. Practical new type content

[0006] The utility model discloses a kind of anchor cable hole video endoscope supporting devices, to solve the problem raised in background art.

[0007] To achieve the above object, the utility model provides the following technical scheme: a kind of anchor cable hole video endoscope supporting device, including the prestressed anchor cable hole drilled on slope, the inside of the prestressed anchor cable hole is viewed the completeness of anchoring section surrounding rock by lowering endoscope supporting device, the endoscope supporting device includes endoscope cable lowered into the prestressed anchor cable hole, industrial endoscope connected to the free end of endoscope cable and located at the deep place of prestressed anchor cable hole, endoscope display instrument connected to the one end of endoscope cable located outside the prestressed anchor cable hole and endoscope alignment component arranged at the lateral side of industrial endoscope, the endoscope alignment component includes upper shell and lower shell symmetrically wrapped in the lateral side of industrial endoscope, the upper shell and lower shell are detachably connected together and then fixed by waterproof adhesive tape winding, the one end of the industrial endoscope extending to the deep place of prestressed anchor cable hole and the side close to endoscope alignment component is provided with guiding protection component, the guiding protection component is half-closed cover and is arranged at the end of endoscope alignment component away from endoscope display instrument, so that the industrial endoscope and endoscope alignment component are lowered into the deep place of prestressed anchor cable hole, the guiding protection component is guided industrial endoscope to smoothly lower by the elastic of itself and the rolling friction generated between hole wall collision contact.

[0008] Preferably, the upper shell and the lower shell are provided with cavities on opposite sides, and the two cavities are spliced together to form a cabin for installing the industrial endoscope.

[0009] Preferably, the industrial endoscope is provided with waterproof flexible filling mortar on the lateral side and in the inner cavities of the two cavities, and part of the waterproof flexible filling mortar overflows from the cabin and fills into the gap between the upper shell and the lower shell.

[0010] In a preferred embodiment, the upper housing has multiple slots symmetrically arranged on the side facing the lower housing, and the lower housing has multiple blocks symmetrically arranged on the side facing the upper housing. When the upper housing and the lower housing are joined together, the blocks engage with the slots to complete the engagement of the upper housing and the lower housing.

[0011] In this preferred embodiment, one end of both the upper housing and the lower housing back-to-back guiding and protective assembly is integrally connected to a cable guide tube, and the two cable guide tubes are spliced ​​together to form a channel for the endoscope cable to pass through.

[0012] In this preferred embodiment, after the upper and lower housings are spliced ​​together, an endoscope tube is fixedly connected to one end of the cable guide tube facing away from the endoscope tube, and a protective cover is detachably connected to the periphery of the endoscope tube.

[0013] In a preferred embodiment of this scheme, the guiding and protective assembly includes a plurality of arc-shaped elastic plates fixed in a ring array to the periphery of the endoscope tube and near one end of the upper and lower housings, and a plurality of guide steel balls respectively rolled and embedded in the outer wall of each arc-shaped elastic plate.

[0014] In this preferred embodiment, the guide steel ball makes rolling friction contact with the hole wall of the prestressed anchor cable hole.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This video endoscope device for anchor cable holes addresses the common problem of incorrect viewing angles in traditional endoscopes, leading to blurry or distorted images that fail to accurately reflect the state of the surrounding rock. The new solution addresses this by using an endoscope alignment component. The industrial endoscope is symmetrically encased in an upper and lower shell, ensuring it maintains the correct viewing angle within the hole. This symmetrical design keeps the lens horizontal in any direction, preventing image distortion or defocusing caused by equipment tilt. When the device is lowered deep into the prestressed anchor cable hole, the alignment component automatically corrects the lens angle through its structural design, ensuring clear and stable images. This solves the problem of incorrect viewing angles in traditional methods, improving the quality and accuracy of video images.

DETAILED DESCRIPTION

[0026] In the following description, numerous specific details are given to provide a thorough understanding of the application. However, it will be apparent that the application can be practiced without one or more of these specific details. In other instances, well-known techniques have not been described in order to avoid obscuring the application.

[0027] Unless specifically defined otherwise, the terms "upper," "lower," "right," "left," "forward," "backward," "inward," and "outward" used herein refer to the orientation of the figures as illustrated in the figures, and are used in this description for ease of description.

[0028] The present embodiment provides a method for manufacturing a device for detecting a position of a cable of an endoscope, comprising the steps of Figs. 1 to 4The device is characterized in that the device comprises a pre-stressed anchor hole 1 drilled on a slope, the inside of the pre-stressed anchor hole 1 is viewed by lowering the endoscope device to check the integrity of the surrounding rock of the anchoring section, the endoscope device comprises an endoscope cable 2 lowered into the pre-stressed anchor hole 1, an industrial endoscope 3 connected to the free end of the endoscope cable 2 and located at the deep part of the pre-stressed anchor hole 1, an endoscope display instrument 5 connected to one end of the endoscope cable 2 outside the pre-stressed anchor hole 1, and an endoscope alignment assembly 4 arranged on the side of the industrial endoscope 3, the endoscope alignment assembly 4 comprises an upper shell 12 and a lower shell 13 symmetrically wrapped around the side of the industrial endoscope 3, the upper shell 12 and the lower shell 13 are detachably connected together and then wrapped and fixed by waterproof tape, one end of the industrial endoscope 3 extending to the deep part of the pre-stressed anchor hole 1 and located close to one side of the endoscope alignment assembly 4 is provided with a guide protection assembly 6, the guide protection assembly 6 is semi-closedly arranged at one end of the endoscope alignment assembly 4 away from the endoscope display instrument 5, so that when the industrial endoscope 3 and the endoscope alignment assembly 4 are lowered into the deep part of the pre-stressed anchor hole 1, the guide protection assembly 6 guides the smooth lowering of the industrial endoscope 3 by the elastic collision and contact with the hole wall and the rolling friction generated between the hole wall. The design of the endoscope alignment assembly 4 can solve the problems of incorrect camera angle, limited coverage and difficult lens in the industrial endoscope video camera detection in the anchor hole, effectively improve the video and camera clarity of the anchor hole, and record the real state of the surrounding rock around the hole in a comprehensive and complete manner. The design of the guide protection assembly 6 not only protects the semi-closed arrangement of the endoscope alignment assembly 4, but also guides the smooth lowering of the industrial endoscope 3 and the endoscope alignment assembly 4, preventing jamming between the hole wall during the lowering process.

[0029] In the embodiment, the upper shell 12 and the lower shell 13 are provided with cavities 15 on opposite sides, and the two cavities 15 are spliced together to form a cabin for mounting the industrial endoscope 3. The design of the cavities 15 enables the upper shell 12 and the lower shell 13 to be accurately aligned and provides a stable mounting space for the industrial endoscope 3, ensuring that it does not shift or loosen during use. Through the design of the cavities 15, the industrial endoscope 3 is firmly fixed in the cabin, reducing the problem of image blur caused by vibration or collision. The detachable design of the upper shell 12 and the lower shell 13 facilitates maintenance and replacement of parts.

[0030] In this embodiment, the industrial endoscope 3 is provided with waterproof flexible filling cement 7 on the side of the two chambers 15, and part of the waterproof flexible filling cement 7 overflows from the chamber and fills the gap between the upper housing 12 and the lower housing 13. The waterproof flexible filling cement 7 not only fills the gap in the chamber, but also overflows from the chamber to fill the gap between the upper and lower housings, enhancing the overall sealing. The waterproof flexible filling cement 7 effectively prevents moisture from entering the chamber, protecting the industrial endoscope 3 from a humid environment. The cement has a certain elasticity and can absorb shocks during equipment lowering, further protecting the industrial endoscope 3.

[0031] In this embodiment, the upper housing 12 is symmetrically provided with a plurality of clamping grooves 14 on the side facing the lower housing 13, and the lower housing 13 is symmetrically provided with a plurality of clamping blocks 16 on the side facing the upper housing 12. When the upper housing 12 and the lower housing 13 are spliced together, the clamping blocks 16 are clamped into the clamping grooves 14 to complete the clamping of the upper housing 12 and the lower housing 13. The design of the clamping grooves 14 and the clamping blocks 16 realizes the quick and accurate docking of the upper and lower housings, ensuring that they are tightly fitted and increasing the stability of the structure. The design of the clamping grooves 14 and the clamping blocks 16 makes the upper and lower housings tightly combined, enhancing the stability of the overall structure. This design simplifies the assembly steps and improves work efficiency.

[0032] In this embodiment, the upper housing 12 and the lower housing 13 are integrally connected with cable guide tubes 11 at one end away from the guide protection assembly 6. The two cable guide tubes 11 are spliced together to form a channel 8 for the endoscope cable 2 to pass through. The design of the cable guide tube 11 provides a fixed path for the endoscope cable 2, ensuring that it does not entangle or be disturbed during lowering. The cable guide tube 11 effectively protects the endoscope cable 2 from damage in complex environments. By fixing the cable path, it reduces interference in signal transmission and improves the reliability of data transmission.

[0033] In this embodiment, the upper housing 12 and the lower housing 13 are spliced together and fixedly connected with an endoscope head tube 10 at one end away from the cable guide tube 11. The endoscope head tube 10 is detachably connected with a protective cover 9 on the side. The endoscope head tube 10 serves as an extension of the front end of the industrial endoscope 3, providing additional support and protection. The protective cover 9 further enhances the protection of the lens. The protective cover 9 effectively protects the endoscope head tube 10 from physical damage in complex underground environments. The detachable design of the protective cover 9 facilitates maintenance and replacement, improving the service life of the equipment.

[0034] In this embodiment, the guide protection assembly 6 includes a plurality of arc-shaped elastic plates 17 fixed to the side of the endoscope head tube 10 and close to one end of the upper shell 12 and the lower shell 13, and a plurality of guide steel balls 18 respectively rollingly embedded in the outer wall of each arc-shaped elastic plate 17. The arc-shaped elastic plate 17 and the guide steel balls 18 thereon are in contact with and roll on the hole wall, reducing the friction force and ensuring smooth lowering of the device in the hole. The rolling characteristics of the guide steel balls 18 significantly reduce the friction force, enabling the device to be smoothly lowered to the predetermined depth. The design of the arc-shaped elastic plate 17 enables it to deform slightly to adapt to the shape of the hole wall, avoiding the device from being stuck on the hole wall. The guide steel balls 18 are in rolling frictional contact with the hole wall of the prestressed anchor hole 1. The rolling frictional contact of the guide steel balls 18 with the hole wall reduces the resistance during the lowering of the device, while also serving as a guide.

[0035] Working principle

[0036] The anchor hole video endoscope matching device connects the industrial endoscope 3 with the endoscope cable 2, and wraps the industrial endoscope 3 with the upper shell 12 and the lower shell 13 to form the endoscope alignment assembly 4. The upper shell 12 and the lower shell 13 are accurately aligned and fixed by the clamping groove 14 and the clamping block 16, and then wrapped and reinforced with waterproof tape. The protective cover 9 is installed on the side of the endoscope head tube 10, and waterproof flexible filling cement 7 is injected into the cavity 15 of the upper shell 12 and the lower shell 13, ensuring that the industrial endoscope 3 is stably placed in the cabin, and part of the waterproof flexible filling cement 7 overflows into the gap between the upper and lower shells, enhancing the sealing performance.

[0037] The guide protection assembly 6 is installed at the end of the endoscope alignment assembly 4 away from the endoscope display instrument 5, and includes a plurality of arc-shaped elastic plates 17 and guide steel balls 18 thereon. These guide steel balls 18 can roll on the hole wall, reducing the friction force and helping the device to be smoothly lowered to the deep part of the prestressed anchor hole 1. The assembled endoscope matching device is slowly lowered through the mouth of the prestressed anchor hole 1. In this process, the guide steel balls 18 in the guide protection assembly 6 are in contact with and roll on the hole wall, reducing the resistance and preventing the device from being stuck or damaged on the hole wall. At the same time, due to the design of the guide protection assembly 6, it can slightly deform to adapt to the shape of the hole wall, ensuring that the device can be smoothly lowered.

[0038] When the industrial endoscope 3 reaches the predetermined depth, it begins to capture image data of the surrounding rock of the anchoring section using its camera. Due to the presence of the endoscope alignment assembly 4, the camera view angle is corrected, ensuring the clarity and coverage of the captured image. The captured video signal is transmitted in real time to the endoscope display instrument 5 through the endoscope cable 2, allowing the operator to view and record the specific conditions of the anchoring section surrounding rock.

[0039] After the video is collected, the endoscope device is slowly pulled out from the pre-stressed anchor cable hole 1, and according to the recorded video data, the technical personnel can comprehensively and accurately evaluate the state of the surrounding rock of the anchoring section, thereby providing a scientific basis for subsequent construction.
