Description

Technical Field

[0001] The utility model relates to the technical field of construction technology tools, in particular to a special drilling rig pad for uneven ground. Background Art

[0002] In the construction of building projects, when it is necessary to drill holes in the building foundation, a drilling rig is generally used to drill holes at a certain design angle. Usually, the construction can be completed when the construction site is general hard soil. However, when the construction site is sandy or soft and watery land, during the installation of the drilling rig, the existing drilling rig bottom support pad has a small foot surface, which makes the drilling rig unable to be stably placed at the drilling position. In addition, when some sand is uneven, the drilling rig is difficult to be supported by the ground, which makes it difficult for the drilling rig to continue working, increasing the difficulty of the drilling work.

[0003] In order to solve the above problems, the prior art usually uses angle steel, steel plates and the like to increase the bottom support surface, so that the drilling rig can also obtain a relatively flat support on uneven ground, and can also provide sufficient supporting force when facing soft ground. For example, the patent document with application number; CN202122958125.3 discloses a geological exploration drilling rig with stable positioning, including a supporting bottom plate and a drilling rig body arranged on the supporting bottom plate, and long fixing blocks are provided on the left and right sides of the supporting bottom plate, and a fixing block along the length of the supporting bottom plate is provided on the long fixing block. A slide groove is arranged in the direction of degrees, and a plurality of sliders are movably arranged in the slide groove. Bolt rods are threadedly connected to the sliders. The bolt rods are arranged longitudinally and a supporting pad is arranged at the lower end. When supporting work is needed, the position of the slide can be adjusted according to different terrains. The threaded rod can be moved upward or downward by twisting the threaded rod, so that the supporting pad can be selectively supported on a better ground. At the same time, the length of the threaded rod can be adjusted to keep the supporting base plate in a horizontal state. In addition, the support of multiple supporting pads can improve the stability of the supporting base plate, so that the drilling rig body can work normally.

[0004] Although the above-mentioned patent can adapt to uneven ground by adjusting the support pads, since there are multiple support pads, each support leg is disconnected from each other. When vibrated, each support leg vibrates independently and has no integrity, which greatly reduces its stability. It cannot be used in sandy or soft and watery land. Otherwise, the support pads will be inserted into the ground during the drilling process, causing the drilling rig to tilt, shift, etc., making it impossible to drill according to the designed angle. Utility Model Content

[0005] The purpose of the utility model is to provide a special drilling rig pad for uneven ground, so as to solve the technical problem that the structure of the adjustable supporting pad in the prior art mentioned above is not stable enough and is not suitable for drilling work in soft and watery sandy land.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a special drilling rig pad for uneven ground, including a support pad that provides a drilling rig foot with an area larger than the cross-sectional area of ​​the support foot, the support pad includes two parallel angle plates, and the two ends of the angle plates are connected to each other by parallel connecting plates to form a frame structure of the support pad, and a sliding groove is opened on the angle plate, and a drilling rig connecting slide plate is slidably connected in the sliding groove, and the drilling rig connecting slide plate is provided with a connecting hole for fixing the drilling rig foot.

[0007] The beneficial effects of this embodiment are:

[0008] 1. In the prior art, the drilling rig pad is provided with a structure of multiple adjustable support pads, so that the area of ​​each support pad cannot be too large. Therefore, the support pad cannot be used in sandy land and soft and watery land. Otherwise, the support pad will be inserted into the ground during the drilling process, causing the drilling rig as a whole to tilt or shift. In the present application, angle plates are provided, and the angle plates are connected into a whole by connecting plates, so that the overall structure is more stable and can better cope with sandy land and soft and watery land.

[0009] Furthermore, the width of the angle plate is more than twice the width of the drilling rig foot. The width of the angle plate makes the drilling rig more stable on sand.

[0010] Furthermore, the two ends of the angle plate are lifted upward to form an arc surface, and the lifting of the arc surface makes it difficult for the two ends of the angle plate to be inserted into the sand during the movement.

[0011] Furthermore, the lower end of the drilling machine connecting slide plate is provided with a slide block sleeved in the slide groove, a fixing hole is opened on the side of the slide block, and a fixing plug hole is provided on the side of the angle plate, which can penetrate into the slide groove from the side, and a fixing pin is provided on the fixing hole and the fixing plug hole. This makes the present application applicable to drilling machines of different specifications, and when the drilling position is slightly adjusted, the slide groove can be used for sliding, without moving the entire device, and it is more convenient to drill equidistant holes.

[0012] Furthermore, the connection plate is provided with a hoisting hole, so that the special drilling rig pad of the present application is convenient for bundling and fixing during hoisting and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic diagram of the structure of the utility model after assembly.

[0014] Figure 2 It is a side cross-sectional view of an embodiment of the utility model.

[0015] Figure 3 It is a front cross-sectional view of the corner plate of an embodiment of the utility model. DETAILED DESCRIPTION

[0016] The following is further described in detail through specific implementation methods:

[0017] The reference numerals in the drawings of the specification include:

[0018] Drilling rig 1, machine rod 11, drilling rig foot 12, supporting pad 2, angle plate 21, fixing socket 211, slide groove 212, connecting plate 22, hanging plate 221, drilling rig connecting slide plate 23, slide block 231, fixing pin 232.

[0019] Implementation example Figures 1 to 3 As shown: a special drilling rig pad for uneven ground includes a supporting pad 2, and the supporting pad 2 increases the area of ​​the drilling rig foot 12 for the drilling rig 1, so that when the drilling rig 1 is operating on sandy or soft land, the drilling rig foot 12 will not be inserted into the ground during the drilling operation of the drill rod 11, forming a tilted and unstable state.

[0020] The supporting pad 2 includes two parallel angle plates 21, the width of the angle plates 21 is twice that of the drilling rig foot, the two ends of the angle plates 21 are lifted upward to form an arc-shaped surface, and the arc-shaped surface is narrowed to form sharp corners at both ends. The middle is a flat thick plate structure, and a slide groove 212 is opened at the upper end of the flat part. Connecting plates 22 are welded at both ends of the angle plates 21, and the two ends of the connecting plates 22 are respectively connected to two different angle plates 21, so that the angle plates 21 and the connecting plates 22 form an integral frame structure, and a lifting plate 221 is provided on the upper end surface of the connecting plate 22, and a lifting hole is opened on the lifting plate 221, so that the special drilling rig pad of the present application is convenient for bundling and fixing during lifting and transportation.

[0021] The chute 212 is slidably connected with a drilling rig connecting slide plate 23, which is parallel to the connecting plate 22, and the two ends are also connected to different angle plates 21. A slider 231 is provided at the lower end of the drilling rig connecting slide plate 23, which is welded to the drilling rig connecting slide plate 23 as a whole. The width of the slider 231 is smaller than the width of the drilling rig connecting slide plate 23, so the slider 231 can be inserted into the chute 212, and the drilling rig connecting slide plate 23 covers the chute 212. The chute 212 is a cavity with a "convex" structure, and the slider 231 can just cooperate with the chute 212, such as Figure 3 As shown, the slider 231 is exactly engaged with the slide slot 212 , so that the slider 231 cannot escape from the slide slot 212 .

[0022] A connecting hole is formed at the upper end of the drilling rig connecting slide plate 23 and passes through the drilling rig connecting slide plate 23. A pad is welded on the drilling rig foot 12, and a threaded rod (not shown in the figure) is provided on the pad, so that the drilling rig foot 12 can be inserted into the connecting hole on the drilling rig connecting slide plate 23 through the threaded rod and fixed with a nut, thereby fixing the drilling rig 1 on the drilling rig connecting slide plate 23.

[0023] A plurality of equally spaced fixing holes 211 are provided on the side of the angle plate 21. By aligning the fixing holes 211 with the fixing holes on the slide block, the fixing pin 232 is inserted from the angle plate 21, so that the drill 1 can be fixed on the angle plate 21, so that the drill 1 does not slide in the slide groove 212 on the angle plate 21 during the drilling operation. When not drilling, the drilling position can be adjusted by sliding, or the drilling work of equal distances can be completed.

[0024] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
