Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a drilling device for foundation concrete lining. Background Art

[0002] At present, the concrete lining of equipment foundation is usually excavated by blasting, installed by formwork, and cast in one go. Since the concrete foundation required by large equipment is large in size, and the equipment needs to reserve a large number of anchor bolts with small reserved size, small wooden formwork is often used on site for installation and pre-embedding, and cast in one go after being fixed. In order to prevent the formwork from moving during the casting process, steel reinforcement and drilling and planting are often used to fix and expand the volume of the reserved bolt holes.

[0003] In a one-time pouring formwork project, due to the small size of the reserved formwork holes, how to install and fix the formwork during construction is a big problem, which is time-consuming and labor-intensive. If the reserved bolt holes cannot match the original design due to displacement or collapse after pouring, the progress of equipment installation will be greatly affected, and the original structure of the concrete will need to be destroyed to open or expand holes, which will increase construction time and labor costs. If the method of drilling out bolt holes after one-time pouring is adopted, special equipment (such as conventional pneumatic rock drilling equipment) is required for drilling and expanding holes. However, the foundation concrete lining generally requires at least two rows of bolt holes to be reserved, and the size is large. The existing drilling rigs are difficult to meet its use requirements. For example, a water-mill drilling rig device with a detachable support with application number 201920035188.1 is arranged on a pad as a whole and needs to be placed on the foundation concrete lining for drilling. On the one hand, it is difficult to locate due to the obstruction of the pad. On the other hand, under the heavy pressure of the drilling rig, the original structure is easily damaged.

A water storage container 4 is suspended in the middle of the cross beam 1. A cooling pipe 5 is arranged on the transverse movement seat 31. One end of the cooling pipe 5 is connected to the water storage container 4, and the other end is fixed on the water mill drill 32 and aligned with the drill bit 321 of the water mill drill 32.

[0031] The using process of the drilling device for basic concrete lining: Place the two support feet 2 respectively as Figure 4On both sides of the shown basic concrete lining 10, adjust to the specified position in the length direction of the basic concrete lining 10; move and adjust the two transverse seats 31 so that the drill bits 321 of the water mill drills 32 on the two transverse seats 31 are vertically aligned with the two bolt holes 101 to be processed on the lower basic concrete lining 10; adjust the height of the water mill drill 32 so that the drill bit 321 of the water mill drill 32 is at an appropriate distance from the basic concrete lining 10; drill two bolt holes 101 on the basic concrete lining 10 through the two water mill drills 32. For this drilling device for the basic concrete lining, on the one hand, drilling with the suspended water mill drill 32 facilitates positioning drilling; on the other hand, only the drill head 321 contacts the basic concrete lining 10, and it is not easy to damage the original structure of the basic concrete lining 10; on the third hand, two holes are processed in one alignment, improving the construction efficiency.

[0032] Furthermore, in this embodiment, the transverse seat 31 is slidably arranged on the cross beam 1 and is provided with a transverse locking member 311 for locking itself on the cross beam 1. The transverse seat 31 moves and adjusts its position along the cross beam 1 to adjust the drilling position of the water mill drill 32. After the position is adjusted, it is locked by the transverse locking member 311.

[0033] Furthermore, in this embodiment, the transverse locking member 311 is threadedly connected to the transverse seat 31 and abuts against the cross beam 1. By rotating the transverse locking member 311 forward and backward, the abutting and separation from the cross beam 1 can be realized, thereby realizing the locking and unlocking of the transverse seat 31.

The locking member 73 is a locking bolt and is inserted into the corresponding through holes.

[0039] Further, in this embodiment, moving wheels 8 and a lifting base 9 are provided at the bottom end of the support feet 2. When the lifting base 9 rises higher than the moving wheels 8, the whole drilling device can move along the length direction of the foundation concrete lining 10 to adjust the drilling position; after reaching the next drilling position, the lifting base 9 descends and supports on the ground to improve the stability during the drilling operation.

[0040] Further, in this embodiment, the lifting base 9 includes a bottom plate 91 and a screw rod 92. The screw rod 92 is threadedly connected to the support feet 2.
