Description

Technical Field

[0001] The utility model belongs to the technical field of drilling rigs, in particular to a lockable drilling rig. Background Art

[0002] When using an auger for land excavation, drilling or foundation engineering, it is true that there may be some challenges, especially when encountering tree roots, stones or other hard objects. When the drill bit of the auger is stuck by these obstacles, it has difficulty advancing smoothly in the soil, and it may even be completely fixed. For the operator, faced with this situation, they must spend a lot of time and effort to try to free it from the ground by turning the auger manually or using mechanical force.

[0003] However, existing auger machines often lack a dedicated device or mechanism to lock the drill bit, which increases the difficulty and uncertainty of operation to a certain extent. When the drill bit is stuck, the lack of a locking device means that the operator needs to operate more carefully and cautiously to avoid further damage to the equipment or threats to their own safety.

DETAILED DESCRIPTION

[0023] The directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention of the utility model.

[0024] like Figure 1-3 As shown, a lockable drilling rig includes a control frame 2, on which an engine 1 is mounted, and the engine 1 is externally driven and connected to a reducer 3, and a drill bit 4 (the drill bit 4 specifically includes a drill rod part, a drill bit 4 part, and a side spiral part) is fixedly connected under the output shaft of the reducer 3. In order to provide stable fixation and rapid locking functions, a fixing plate 5 is fixedly connected to the control frame 2, and a first pin hole 31 is provided on the fixing plate 5, and a second pin hole 51 is provided on the output shaft of the reducer 3. Further, in order to achieve the locking operation, a fixing seat 6 is connected to the control frame 2, and a connecting member 7 is connected to the fixing seat 6, and a pin shaft 8 for passing through the first pin hole 31 and the second pin hole 51 is connected to the end of the connecting member 7, so that when necessary, the drill bit 4 can be quickly locked or unlocked by simply plugging and pulling the pin shaft 8, thereby facilitating manual operation and releasing the drill rod stuck in the soil after shaking or pulling it out.

[0025] Specifically, in order to provide sufficient flexibility and reliability, the connecting member 7 is a chain. The design of the chain connection not only allows fine adjustment within a certain range, but also can withstand greater tension, thereby improving durability.

[0026] Specifically, the control frame 2 includes a support frame 21, a front support frame 22 and a rear support frame 23. The support frame 21 is in a square frame shape. The engine 1 is installed on the upper side of the support frame 21. The front support frame 22 and the rear support frame 23 are fixedly connected to the lower side of the support frame 21. The drill bit 4 is arranged between the front support frame 22 and the rear support frame 23, ensuring the stability and convenience of operation of the drill bit 4. At the same time, the two ends of the fixing plate 5 are respectively fixedly connected to the front support frame 22 and the rear support frame 23, and the front and rear sides are symmetrically arranged and distributed, with two in total. The pin shaft 8 passes through the first pin holes 31 of the two fixing plates 5 to improve the stability and bending resistance of the pin shaft 8.

[0027] In order to make the control frame 2 more ergonomic, the front bracket 22 and the rear bracket 23 are arc-shaped curved pipes, which are opened upward and symmetrically arranged about the vertical plane. The front bracket 22 and the rear bracket 23 are symmetrically arranged front and back, which further enhances the stability of the overall structure and can also play a protective role.

[0028] In order to facilitate the operator to operate the drill bit 4, the support frame 21 is fixedly connected to a hand support frame 9, and the hand support frame 9 is fixedly connected to a handle 10 and a control handle 11. The handle 10 and the control handle 11 are extended forward and backward, and the hand support frame 9 is symmetrically arranged about the vertical plane, so that the operator can hold the handle 10 and operate the control handle 11 more comfortably.

[0029] In order to simplify the installation and disassembly process, a slot is provided in the middle and lower part of the fixing seat 6, and the fixing seat 6 is connected to the support frame 21 through the slot. The fixing seat 6 can be conveniently fixed on the support frame 21, and it is also convenient to disassemble when needed; a storage hole 61 is provided in the middle and upper part of the fixing seat 6, and the pin shaft 8 can be operably inserted into the storage hole 61, which is convenient for storage and prevents the work from being affected after being scattered at will; and the pin shaft 8 specifically includes a limit head 81 and a limit column 82 that are fixedly connected to each other, and the limit head 81 is connected to the connecting member 7, and the diameter of the limit head 81 is larger than the inner diameter of the first pin hole 31 and the second pin hole 51, so that it is easy to be inserted in place.

[0030] Finally, in order to ensure a stable connection between the drill bit 4 and the output shaft, the lower end of the output shaft is connected to the drill bit 4 through a sleeve and a fixing pin, so that the drill bit 4 can maintain stable performance even when rotating at high speed.

[0031] In summary, the utility model adopts innovative designs such as chain connection, ergonomically designed hand support 9 and control handle 11, and slot-connected fixing base 6, which not only improves the stability of the drill bit 4 and the convenience of operation, but also simplifies the installation and disassembly process, bringing a more efficient and comfortable experience to the user.
