Description

Technical Field

[0001] The utility model relates to the technical field of deep - hole peeping, in particular to a crawler - type underground deep - hole peeping lens auxiliary pushing device suitable for inclined holes. Background Technique

[0002] In underground deep - hole peeping operations, as the hole depth increases, it is often difficult to ensure the straightness of the drill hole. The deviation of the drill - hole direction is extremely likely to cause the lens to get stuck during the pushing process of the long rod. Frequent adjustment of the lens will increase the operation time and reduce work efficiency. Moreover, the use of the long rod may cause accidental collisions or drops, further increasing the safety risks. In addition, traditional peeping equipment mainly relies on manually pushing the lens with a metal long rod, which has problems such as high labor intensity, low operation accuracy, low efficiency, and safety hazards during deep - hole operations. This not only consumes a large amount of physical strength but also easily causes the lens to be unstable, thus affecting the clarity and accuracy of the image. Therefore, there is an urgent need for a new type of deep - hole peeping lens auxiliary pushing device to achieve stable, fast, and safe propulsion of the lens in the drill hole of the inclined deep hole, thereby improving the overall efficiency and safety of deep - hole operations.

The propulsion assembly includes a power propulsion device, rollers, a connecting rod, and a roller bracket. The lens is installed on the connecting rod, and the other end of the connecting rod is connected to the power propulsion device. A plurality of pairs of roller brackets are movably arranged outside the power propulsion device, and rollers are movably arranged at the ends of the roller brackets. A shock - absorbing spring is connected between the roller bracket and the connecting rod, and a power transmission assembly is arranged between the propulsion device and the rollers. This technical solution can facilitate the equipment to pass smoothly and stably when encountering a bad drill - hole environment by setting the roller bracket, rollers, and shock - absorbing spring, and can also prevent the lens from being damaged due to collision with the hole wall, affecting normal use; it is equipped with a power propulsion device, which can overcome the self - weight of the equipment and save time and effort when detecting deeper horizontal drill holes, drill holes inclined upward at a certain angle, and vertically upward drill holes. However, this technical solution is not suitable for inclined holes, has low operation accuracy, and cannot effectively protect the peeping lens. Content of the Utility Model

[0004] In order to solve the problems in the above - mentioned prior art that manually pushing the lens with a metal long rod is not suitable for inclined holes, has low operation accuracy, and cannot effectively protect the peeping lens.

[0027] The advantages and characteristics of the utility model will be illustrated and explained through the non-restrictive description of the following preferred embodiments, which are given only as examples with reference to the drawings.

[0028] As Figures 1 to 7As shown in the figure, the utility model provides a crawler-type downhole deep-hole peeping lens auxiliary pushing device applicable to deflected holes, including a housing 1. The housing 1 is cylindrical as a whole and its outer diameter is smaller than the inner diameter of the drilling hole 7. A plurality of annular cavities 11 are arranged on the outer wall of the housing 1. The plurality of annular cavities 11 are arranged along the axial direction of the housing 1. A number of crawler traveling mechanisms 2 are arranged in the cavities 11 at equal intervals in an array. Preferably, the number of crawler traveling mechanisms 2 in a single cavity 11 is three. The crawler traveling mechanisms 2 are arranged along the axial direction of the housing 1. The crawler traveling mechanisms 2 are fixedly connected to the housing 1 through hydraulic cantilevers 4. A lens fixing sleeve 3 is fixedly connected to the tail end of the housing 1 along the advancing direction of the peeping lens 6 for connecting the peeping lens 6.

[0029] The crawler traveling mechanism 2 includes a driving wheel 22 and a crawler 21 sleeved on the driving wheel 22, which is used to pull the device forward in the drilling hole 7. The crawler 21 is independently driven by the driving wheel 22 and controlled to move forward or backward through a remote control module. It can still maintain good grip and traction in deep holes with a small radius of curvature, realizing effective propulsion in a non-straight hole environment, adapting to medium-deep drilling holes 7 with different angles and curvatures, and ensuring the flexibility and operation convenience of the device in the drilling hole 7. As Figure 7 shown. Preferably, the crawler 21 is made of rubber, which can avoid damaging the inner wall of the drilling hole 7.

[0030] Both ends of the hydraulic cantilever 4 are connected to the housing 1 and the crawler traveling mechanism 2 through hinge structures. Each crawler traveling mechanism 2 is connected by three groups of hydraulic cantilevers 4. Two of the hydraulic cantilevers 4 are inclined towards the tail end of the housing 1 along the advancing direction of the peeping lens 6, and the other group of hydraulic cantilevers 4 is inclined towards the head end of the housing 1 along the advancing direction of the peeping lens 6, ensuring that the hydraulic cylinder of the hydraulic cantilever 4 has enough compression stroke. The structure of the cantilever hydraulic 4 can automatically adjust the position of the peeping lens 6, enabling the device to adapt to different hole diameters and the changing curvature of the drilling hole 7, enabling the device to meet different hole diameter requirements, and at the same time maintaining the stability of the peeping lens 6 during the propulsion process.

[0031] The lens fixing sleeve 3 is a hollow semi-circular ring structure. The outer wall of the lens fixing sleeve 3 is provided with threads for fixedly connecting with the housing 1. The inner wall of the lens fixing sleeve 3 is provided with threads for connecting with a threaded part 61 arranged at the end of the peeping lens 6 away from the lens. A cable notch 32 is arranged on the side of the lens fixing sleeve 3, which is convenient for the installation of the peeping lens 6. As Figure 5 shown. A gasket 31 is also arranged at the contact part between the lens fixing sleeve 3 and the peeping lens 6. The gasket 31 is made of an elastic material, preferably rubber, to provide shock absorption protection and further enhance the stability of the peeping lens 6 during the propulsion process.

[0032] As Figure 3As shown, a buffer pad 5 is provided inside the outer shell 1. The buffer pad 5 is made of wear-resistant and shock-absorbing sponge to reduce the jitter of the peeping lens 6 during the propulsion process and improve the imaging quality.

[0033] In addition to the above embodiments, the present utility model may also have other implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present utility model.
