Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated pile production, and in particular to a drill rod storage device and a pile driver. Background Art

[0002] At present, the pile driving depth of pile drivers used in construction sites is often much greater than their height. The length of a single drill rod is limited by the height of the pile driver and cannot meet the required depth of pile driving. In order to solve this problem, pile drivers usually reserve multiple sections of connectable drill rods for extension operations to meet construction requirements.

[0003] During the construction process, it is necessary to repeatedly connect and unload drill rods. At present, the unconnected drill rods or the unloaded drill rods are stacked horizontally next to the pile driver. When connecting and placing the drill rods, the drill rods need to be adjusted in the horizontal and vertical positions, which is troublesome and time-consuming. In addition, due to the lack of a suitable storage device, the drill rods are stacked in a messy manner. The operators have to spend time moving and arranging the drill rods after each use, which causes many inconveniences to the work and wastes a lot of unnecessary time. In addition, the drill rods are heavy, which makes the arrangement operation of the drill rods very inconvenient. Summary of the invention

[0004] In order to solve the technical problem of the existing messy storage of drill rods, the present invention provides a drill rod storage device and a pile driver to reasonably store the drill rods and facilitate the drill rod storage operation.

[0005] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0006] A drill rod storage device comprises a storage rack provided with a drill rod inlet and outlet channel and two or more clamping mechanisms arranged in sequence on the storage rack in a transverse direction and used for clamping and fixing the drill rod. The storage rack has a placement space for vertically placing the drill rod. The clamping mechanism comprises at least one clamping block and at least one first driving member. The first driving member is installed and fixed on the storage rack and connected to the clamping block to drive the clamping block to move so as to clamp or release the drill rod.

[0007] Compared with the prior art, the present invention provides a drill rod storage device, which places drill rods through the placement space of the storage rack, and then drives the clamping block to move to clamp or release the drill rod through the first driving member of the clamping mechanism, thereby realizing the management of the placement of the drill rods. The drill rods can be stored reasonably, conveniently and orderly, and the time for stacking the drill rods after use can be reduced, and the work difficulty and intensity of the operators can be reduced, thereby improving work efficiency and safety. Moreover, since the drill rods are placed vertically in the drill rod storage device, there is no need to adjust the direction of the drill rod when connecting the drill rod, thereby reducing the difficulty of operation.

[0008] Furthermore, the storage rack includes a first limiting frame, a second limiting frame and a base plate that form a placement space. The first limiting frame and the second limiting frame are arranged opposite to each other and are separated on both sides of the arrangement direction of the clamping mechanism. The bottom ends of the first limiting frame and the second limiting frame are both installed and fixed on the base plate, and one lateral end of the first limiting frame and one lateral end of the second limiting frame are connected and fixed by a connecting rod. A drill rod inlet and outlet channel is formed between the other lateral end of the first limiting frame and the other lateral end of the second limiting frame, and the drill rod inlet and outlet channel is located next to the drill rod working area. The drill rod can enter and exit the placement space of the storage rack through the drill rod inlet and outlet channel, which is convenient for the operator to operate the drill rod in and out.

[0009] Furthermore, the storage rack is provided with a channel opening and closing control mechanism at the drill rod inlet and outlet channel. The channel opening and closing control mechanism includes a second driving member installed on the first limiting frame and an opening and closing member driven by the second driving member and retractable to the second limiting frame to close or open the drill rod inlet and outlet channel. The drill rod inlet and outlet channel is closed or opened by the channel opening and closing control mechanism, thereby enhancing the control over the drill rod inlet and outlet and preventing the drill rod from accidentally moving out of the storage rack.

[0010] Preferably, the channel opening and closing control mechanism also includes a third driving member installed on the first limiting frame. The third driving member is located next to the second driving member and is used to drive the channel opening and closing control mechanism to deflect away from or close to the second limiting frame. The third driving member drives the channel opening and closing control mechanism to deflect to prevent the channel opening and closing control mechanism from affecting the drill rod entering and exiting the storage rack.

[0011] In addition, the present invention also provides a pile driver, the specific scheme is as follows:

[0012] A pile driver comprises a pile driver body and the aforementioned drill rod storage device, wherein a plurality of fixing rods for connecting and fixing the drill rod storage device are evenly arranged between the pile driver body and the drill rod storage device.

[0013] The pile driver provided by the present invention comprises the aforementioned drill rod storage device, and thus has the same function as the drill rod storage device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 2

[0030] In this embodiment, the same parts as those in the first embodiment are given the same figure marks, and the same text descriptions are omitted.

[0031] See also Figure 2, Figure 3 , Figure 4 , Figure 4 yes Figure 2 In the enlarged schematic diagram of part B, compared with the first embodiment, the drill rod storage device 20 provided in this embodiment has the following different structural designs:

[0032] The storage rack 21 includes a first limiting frame 213, a second limiting frame 214 and a bottom plate 215 forming a placement space 212. The first limiting frame 213 and the second limiting frame 214 are arranged opposite to each other and are separated on both sides of the arrangement direction of the clamping mechanism 22 (i.e., both sides of the drill rod 1). The bottom ends of the first limiting frame 213 and the second limiting frame 214 are both fixedly mounted on the bottom plate 215, and the lateral direction (i.e., the lateral direction) of the first limiting frame 213 is Figure 2 The first limiting frame 213 and the second limiting frame 214 are connected and fixed by a connecting rod 216, and a drill rod inlet and outlet passage 211 is formed between the other lateral end of the first limiting frame 213 and the other lateral end of the second limiting frame 214, and the drill rod inlet and outlet passage 211 is located beside the working area of ​​the drill rod 1. A placement space 212 for placing the drill rod 1 is formed between the first limiting frame 213, the second limiting frame 214 and the bottom plate 215, and the storage rack 21 is fixed to the pile driver body 10 by a fixing rod 30. The drill rod 1 can be placed or taken out from the placement space 212 of the storage rack 21 when it is disassembled and docked, and a drill rod inlet and outlet passage 211 is formed between the first limiting frame 213 and the second limiting frame 214, and the drill rod inlet and outlet passage 211 is located beside the working area of ​​the drill rod 1 of the pile driver body 10, so that the drill rod 1 can be easily put in and out of the drill rod inlet and outlet passage 211, so that it is easy to handle the drill rod 1. This is the specific structure of the storage rack 21, but the structure of the storage rack 21 is not limited to this. The storage rack 21 in the present invention only needs to have a frame forming a placement space 212 and a drill rod inlet and outlet channel 211 on the frame.

[0033] Preferably, the top height of the storage rack 21 is lower than the top height of the drill rod 1 , so that the drill rod 1 can be easily moved into and out of the placement space 212 of the storage rack 21 , thereby facilitating the operator to place or take out the drill rod 1 .

The second driving member 231 provided on the first limiting frame 213 drives the opening and closing member 232 to move toward or away from the second limiting frame 214, so that the opening and closing member 232 closes or opens the drill rod inlet and outlet channel 211 between the first limiting frame 213 and the second limiting frame 214. The channel opening and closing control mechanism 23 is provided to control the closing or opening of the drill rod inlet and outlet channel 211, so as to prevent the drill rod 1 from accidentally moving out of the storage rack 21, thereby improving safety.

[0040] The channel opening and closing control mechanism 23 also includes a third driving member 233 installed on the first limiting frame 213. The third driving member 233 is located beside the second driving member 231 and is used to drive the channel opening and closing control mechanism 23 to deflect away from or approach the second limiting frame 214. The third driving member 233 located beside the channel opening and closing control mechanism 23 drives the channel opening and closing control mechanism 23 (i.e., the second driving member 231 and the opening and closing member 232) to deflect and move away from or toward the second limiting frame 214, so that the drill rod inlet and outlet channel 211 can be opened to the maximum when the drill rod 1 is stored, which is convenient for placing the drill rod 1.

[0041] Preferably, one end of the opening and closing member 232 extending toward the second limiting frame 214 is hooked so that when the opening and closing member 232 is retracted toward the first limiting frame 213, it hooks the second limiting frame 214 to close the drill rod inlet and outlet channel 211. The hooked opening and closing member 232 hooks the second limiting frame 214 to prevent the opening and closing member 232 from excessively retracting the drill rod inlet and outlet channel 211 to be in an open state, and the opening and closing member 232 hooks the second limiting frame 214 to prevent the channel opening and closing control mechanism 23 from being easily knocked open when the drill rod 1 moves accidentally.
