After searching, the prior art (application number: CN202221895971.3) records "a dual-purpose skydrill chassis, including a structural frame and rail wheels installed thereon, the lowest position of the rail wheels is higher than the lowest surface of the structural frame. The structural frame includes longitudinal beams on both sides and connecting members between the longitudinal beams, the bottom surfaces of the head section and the tail section of the longitudinal beam are both higher than the bottom surface of the middle section, and the bottom surface of the middle section is a horizontal plane; the head section of the longitudinal beam is provided with an upward concave 7-shaped notch, and the tail section includes an upper inclined section and a horizontal section behind it; the rail wheels have two pairs, front and rear, respectively installed on the inner side of the 7-shaped notch corresponding to the head section of the longitudinal beam and the inner side of the horizontal section of the tail section. The chassis can be equipped with rail wheels without changing the structure of the traditional skydrill chassis structural frame, so it can be interchangeable with the chassis of the traditional skydrill, so that the environmental adaptability of the traditional skydrill is improved, and the chassis of the traditional skydrill can also be modified, and the modification cost is low."

[0003] However, although the shaft drilling rig chassis in the prior art has achieved a dual-purpose effect, it still has some shortcomings: when the existing shaft drilling rig chassis is traveling on the track with the drilling rig, it is easily scratched by the stones on the ground due to the presence of many stones on the ground of the mine. In severe cases, it is easily squeezed by the stones and deformed. At the same time, when the rollers at the lower end of the chassis are traveling on the track, they are also easily blocked by smaller stones, causing the stones to collapse, which may cause safety accidents that injure people. Secondly, the existing chassis is generally made of single-layer stamping material, and the mechanical strength and anti-corrosion effect are poor. Utility Model Content

[0004] In order to overcome the defects of the prior art, an anti-corrosion type skydrill chassis is provided to solve the problems that the existing skydrill chassis has poor mechanical strength, no anti-corrosion effect, and is easily scratched by stones or even squeezed and deformed.

[0005] In order to achieve the above-mentioned purpose, an anti-corrosion type skylight drilling rig chassis is provided, including: an upper chassis, a cleaning piece and a lower chassis, wherein wheel frames are provided at the four corners of the lower end of the upper chassis, and rollers are installed on the inner side of the wheel frames, the cleaning piece is installed on the outer side of the rollers, and the cleaning piece includes an air outlet installed on an inclined shovel plate and the lower end of the inclined shovel plate, the lower chassis includes induction plates on both sides and a bottom plate hinged in the middle, and an elastic telescopic rod is connected between the induction plate and the upper chassis, and a connecting rod is hinged on the upper side of the induction plate, the upper end of the connecting rod is connected to a ball head, and the ball head is rotatably connected to a movable sleeve, and a pressure sensor is connected to the upper end of the movable sleeve, reinforcing ribs and cross rods are welded on the lower side of the bottom plate, and the lower end faces of the bottom plate and the induction plate are provided with an anti-corrosion spray coating.

[0006] Furthermore, the upper end of the inclined shovel plate is hinged to the two side edges of the upper chassis, and the upper side of the inclined shovel plate is connected to the flow cavity opened inside the upper chassis through an air pipe, and an air pump is connected to the outer port of the flow cavity.

[0007] Furthermore, a cavity is provided inside the inclined shovel plate, and an air outlet is communicated with the inside of the cavity, and an air blowing direction of the air outlet is toward the front side of the roller.

[0008] Furthermore, the lower end surface of the induction plate is kept inclined with respect to the ground, and the induction plate is located between the front and rear wheel frames, while the outer side of the induction plate does not exceed the outer edge of the upper chassis.

[0009] Furthermore, both upper and lower ends of the elastic telescopic rod are rotatably connected, and the elastic telescopic rod includes a piston rod, a sleeve, and a spring arranged inside the sleeve.

[0010] Furthermore, the movable sleeve is configured as a hollow hemispherical structure, and the ball head always keeps in contact with the movable sleeve.

[0011] Furthermore, mounting plates are welded to the front and rear sides of the bottom plate, and mounting holes are provided inside the mounting plates. The mounting plates are fixedly connected to the upper chassis by bolts.

[0012] The beneficial effects of the utility model are:

[0013] 1. When the rollers of the chassis are running on the track, the cleaning parts avoid sliding on the track. When small stones appear, the stones are blown away through the air outlet at the front end of the inclined shovel. The stones that cannot be blown away are shoveled away by the inclined shovel, thereby protecting the stones on the track from being squeezed and bounced by the rollers, causing safety hazards of injuring people and objects;

[0014] 2. When a stone appears on the lower side of the chassis, the inclined sensing plate contacts the stone in the forward or backward direction of the track and is squeezed and rotated. At the same time, pressure is applied to the pressure sensor through the connecting rod, ball head and movable sleeve. Then, the pressure sensor is electrically connected to the external controller to control the drilling rig to stop linear driving, thereby protecting the lower side of the chassis from being squeezed, scratched or even deformed by the stone.

[0015] 3. The upper chassis and the lower chassis have a double-layer chassis structure to strengthen the thickness of the chassis. At the same time, when the lower chassis is damaged, it can be replaced as a whole, which is convenient for maintenance. In addition, the structural strength of the lower chassis is strengthened by reinforcing ribs and cross rods. At the same time, by spraying anti-corrosion (asphalt material) on the lower chassis, a protective layer structure is added to the lower chassis, which increases the anti-corrosion effect of the chassis.

[0024] In this embodiment, the upper chassis 1 and the lower chassis 4 constitute the main structure of the chassis of the corrosion-resistant skydrilling rig involved in this application.

[0025] The upper side of the upper chassis 1 is connected with drilling equipment and power equipment, and the chassis and the drilling equipment are driven by the power equipment to travel on a preset track.

[0026] The roller 3 is rollingly engaged with the track through the wheel groove to achieve guided movement, and at this time, the lower end of the cleaning member 2 slides on the upper side of the track.

[0027] Among them, the anti-corrosion spray layer 45 is set as asphalt anti-corrosion material.

[0028] like Figure 1 and Figure 4 As shown, the upper end of the inclined shovel plate 22 is hinged on the two side edges of the upper chassis 1, and the upper side of the inclined shovel plate 22 is connected to the flow cavity opened inside the upper chassis 1 through the air pipe 21, and the outer port of the flow cavity is connected to a blowing pump, a cavity is opened inside the inclined shovel plate 22, and the air outlet 23 is connected to the inside of the cavity, and the blowing direction of the air outlet 23 is toward the front side of the roller 3.

[0029] It should be noted that the air pump is installed on the upper side of the upper chassis 1, connected to the air inlet outside the circulation cavity through a pipeline, and then connected to the inclined shovel plate 22 through an air pipe 21 (hose material), and finally sprayed out from the air outlet 23 through the cavity.

[0030] like Figure 1 , Figure 5 and Figure 6As shown, the lower end surface of the sensing plate 41 maintains an inclined state with respect to the ground, and the sensing plate 41 is located between the front and rear wheel frames 5. At the same time, the outer side of the sensing plate 41 does not exceed the outer edge of the upper chassis 1. The upper and lower ends of the elastic telescopic rod 411 are both rotatably connected, and the elastic telescopic rod 411 includes a piston rod, a sleeve and a spring arranged inside the sleeve. The movable sleeve 414 is set as a hollow hemispherical structure, and the ball head 413 always keeps in contact with the movable sleeve 414. The front and rear sides of the bottom plate 42 are both welded with mounting plates 46, and mounting holes are opened inside the mounting plate 46. At the same time, the mounting plate 46 is fixedly connected to the upper chassis 1 by bolts.

[0031] As a preferred embodiment, by setting the induction plate 41 in an inclined state, it is easy to achieve inclined contact with the stone on the lower side of the chassis, thereby generating a lateral squeezing effect. (At this time, the stone is located between the two rollers 3, i.e., the tracks).

[0032] It should be noted that the pressure sensor 415 is electrically connected to the drilling rig driving device. When the pressure sensor 415 detects the contact force between the stone and the chassis, the driving device can stop moving.

[0033] As a preferred embodiment, the lower chassis 4 is configured as a detachable connection structure so that it can be replaced as a whole when damaged, thereby preventing the entire drilling rig from being disabled due to damage to a single chassis structure.

[0034] When in use, when the rollers of the chassis are rolling on the track, the cleaning parts at this time avoid sliding on the track. When small stones appear, the stones are blown away through the air outlet at the front end of the inclined shovel plate, and the stones that cannot be blown away are shoveled away by the inclined shovel plate, thereby protecting the stones on the track from being squeezed and bounced away by the rollers, causing safety hazards of injuring people or property; when stones appear on the lower side of the chassis, they are first squeezed and rotated after contacting the stones through the inclined sensing plate in the forward or backward direction of the track, and at the same time, pressure is applied to the pressure sensor through the connecting rod, the ball head and the movable sleeve, and then the pressure sensor is electrically connected to the external controller to control the drilling rig to stop linear drive, thereby protecting the lower side of the chassis from being squeezed, scratched or even deformed by the stones.

[0035] The anti-corrosion skydrill chassis of the utility model can effectively solve the problems of poor mechanical strength of the existing skydrill chassis, no anti-corrosion effect, and easy scratching or even squeezing and deformation by stones. It is realized by setting a double-layer chassis structure on the basis of the existing anti-corrosion skydrill chassis technology, thereby enhancing the mechanical strength of the chassis, having a certain anti-corrosion effect, and increasing the cleaning of stones and the detection sensing of stones, thereby further protecting the drilling rig chassis.
