[0037] The utility model provides an auxiliary device for loading and unloading a drill rod, aiming to solve the problems of high labor intensity and poor safety of workers in the prior art.

[0038] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, in an embodiment of the utility model, a drill rod loading and unloading auxiliary device is provided, which is used to push the lower end of the drill rod when installing the drill rod so that the internal threaded end of the drill rod is aligned with the main shaft of the power head 810; the drill rod loading and unloading auxiliary device 600 includes a slide rail 100, an auxiliary trolley 200 and a driving mechanism 300, the auxiliary trolley 200 includes a vehicle body 210 and a connecting member 220, the vehicle body 210 is slidably arranged on the slide rail 100, the connecting member 220 is movably arranged on the vehicle body 210, and the connecting member 220 is used to connect with the drill rod 600; the driving mechanism 300 is arranged on the slide rail 100, the driving mechanism 300 is connected to the vehicle body 210, and the driving mechanism 300 can drive the vehicle body 210 to slide when installing the drill rod 600.

[0039] In the embodiment of the utility model, the connecting member 220 is used to connect with the external thread end of the drill rod 600 (i.e., the lower end of the drill rod 600 when it is hoisted), and the connecting member 220 is movably installed on the vehicle body 210, which enables the connecting member 220 to move as the position of the drill rod 600 changes when the drill rod 600 is installed; the driving mechanism 300 can drive the vehicle body 210 to slide and drive the connecting member 220 to move. When the drill rod 600 is installed, the internal thread end of the drill rod 600 (i.e., the upper end of the drill rod 600 when it is hoisted) is hoisted by the wire rope 700 of the winch, and the external thread end of the drill rod 600 is connected to the connecting member 220. At this time, the driving mechanism 300 can drive the vehicle body 210 to slide on the slide rail 100 and drive the connecting member 220 to move, so as to balance the horizontal pulling force generated when the drill rod 600 is hoisted, so that the internal thread end of the drill rod 600 is aligned with the main shaft of the power head 810. In the related art, the loading and unloading of the drill rod 600 is mainly realized by the auxiliary trolley 200 and manual cooperation. However, when installing the drill rod 600, it is necessary to manually drag the external thread end of the drill rod 600 horizontally to balance the horizontal pulling force generated when the drill rod 600 is lifted, so that the internal thread end of the drill rod 600 is aligned with the main shaft of the power head 810, which will increase the labor intensity of the workers, and the workers' operation is highly dangerous, which poses a safety risk. The auxiliary device for loading and unloading the drill rod 600 sets the auxiliary trolley 200 on the slide rail 100 in a sliding manner, and the auxiliary trolley 200 is driven to slide by the driving mechanism 300, that is, the auxiliary trolley 200 is powered by the driving mechanism 300 to drive the auxiliary trolley 200 to slide, and balance the horizontal pulling force generated when the drill rod 600 is lifted. It can replace manual work to complete the dragging work of the external thread end of the drill rod 600, reduce the labor intensity of the workers, and at the same time, it can also reduce the operating danger of the workers and ensure the safety of the workers.

[0040] like Figure 1 , Figure 3 and Figure 4As shown, the driving mechanism 300 includes a driving body 310, a driving sprocket 320 and a driven sprocket 330, the driving sprocket 320 and the driven sprocket 330 are arranged at both ends of the slide rail 100, the driving sprocket 320 and the driven sprocket 330 are connected by a chain 340, the driving body 310 is arranged at one end of the slide rail 100 close to the driving sprocket 320, and the output shaft of the driving body 310 is connected to the driving sprocket 320, and the vehicle body 210 is connected to the chain 340. The driving mechanism 300 drives the vehicle body 210 to slide by chain transmission, and the chain transmission has the characteristics of reliable operation, simple structure and low manufacturing cost, which can ensure the normal operation of loading and unloading the drill rod 600, and can also simplify the auxiliary device for loading and unloading the drill rod 600, saving manufacturing cost. In addition, the driving mechanism 300 can also drive the vehicle body 210 to slide by means of belt drive, screw drive, etc., but it should be noted that, compared with belt drive, chain drive has the characteristics of no elastic sliding and no slipping, which can ensure the normal loading and unloading of the drill rod 600; compared with screw drive, chain drive has the characteristics of low manufacturing and installation precision requirements, which can save costs; at the same time, the drill rod loading and unloading auxiliary device is mainly used to assist the drilling rig 800 to complete the loading and unloading of the drill rod 600, that is, the drill rod loading and unloading auxiliary device needs to work under harsh environmental conditions and needs to withstand a large load, and the chain drive has strong environmental adaptability and overload capacity, which can meet the use requirements of loading and unloading the drill rod 600, so it is preferred to use chain drive to drive the vehicle body 210 to slide.

[0041] like Figure 4 As shown, a tensioning mechanism 400 is provided at one end of the slide rail 100 close to the driven sprocket 330, and the tensioning mechanism 400 includes a fixed plate 410, a movable block 420 and an adjusting member 430. The fixed plate 410 is connected to one end of the slide rail 100 close to the driven sprocket 330, the movable block 420 is arranged on one side of the fixed plate 410 close to the driven sprocket 330, the driven sprocket 330 is rotatably arranged on the movable block 420, and the adjusting member 430 movably passes through the fixed plate 410 and is connected to the movable block 420. By adjusting the adjusting member 430, the worker can adjust the distance between the driven sprocket 330 and the driving sprocket 320, so as to tension the chain 340, avoid the chain 340 from slipping and rubbing during transmission, extend the service life of the chain 340 and the sprocket, and also ensure the stability and reliability during transmission.

[0042] like Figure 4As shown, the adjusting member 430 includes a bolt 431 and a nut 432. The threaded section of the bolt 431 passes through the movable block 420 and the fixed plate 410 in sequence. The nut 432 meshes with the threaded section of the bolt 431, and the nut 432 abuts against the side of the fixed plate 410 away from the movable block 420. When adjusting the tension of the chain 340, the worker only needs to turn the nut 432 to increase or decrease the length of the bolt 431 extending out of the fixed plate 410, thereby driving the driven sprocket 330 to move away from or close to the driving sprocket 320, thereby completing the adjustment of the tension of the chain 340; the adjustment of the tension of the chain 340 is achieved by the cooperation of the bolt 431 and the nut 432, which can simplify the structure of the auxiliary device for loading and unloading the drill rod 600 and reduce the production cost.

[0043] like Figure 6 As shown, the connecting member 220 includes a connecting head 221 and a connecting frame 222, the connecting frame 222 is rotatably arranged on the vehicle body 210, the connecting head 221 is rotatably connected to one end of the connecting frame 222 away from the vehicle body 210, and the connecting head 221 is used to connect with the external thread end of the drill rod 600. The connecting head 221 is rotatably connected to the connecting frame 222, and the connecting frame 222 is rotatably connected to the vehicle body 210, that is, the height position of the connecting head 221 is adjustable, which enables the connecting head 221 to be connected to a variety of drill rods 600 of different diameters, so as to improve the application range of the auxiliary device for loading and unloading drill rods; in this embodiment, the connecting frame 222 is rotatably arranged on the top of the vehicle body 210, and the connecting frame 222 can rotate in a direction close to or away from the vehicle body 210, the connecting head 221 can rotate in a direction close to or away from the vehicle body 210, and the end of the connecting head 221 away from the connecting frame 222 is formed with an internal thread hole that can engage with the external thread end of the drill rod 600. It should be noted that when installing the drill rod 600, the connecting head 221 needs to be aligned with the drill rod 600, that is, the central axis of the connecting head 221 needs to coincide with the central axis of the drill rod 600. When installing drill rods 600 of different diameters, the central axis of the drill rod 600 is in different positions. By connecting the connecting head 221 to the connecting frame 222 and rotatably connecting the connecting frame 222 to the vehicle body 210, the connecting head 221 can be in multiple different positions to meet the installation requirements of drill rods 600 of various different diameters.

[0044] In one embodiment, the connecting frame 222 is rotatably connected to the vehicle body 210 via a cross bearing, and the connecting head 221 is connected to the connecting frame 222 via a cross bearing. A cross bearing is a bearing composed of one or more rotating rollers and one or more retaining frames, and has a structure similar to a universal joint; the connecting frame 222 and the vehicle body 210, as well as the connecting head 221 and the connecting frame 222 are connected by cross bearings, which allows the connecting head 221 to swing laterally within a certain angle range (about 5°) to adapt to the position offset between the on-site drilling rig 800 and the slide rail 100. It should be noted that in the actual construction process, the slide rail 100 needs to be installed on one side of the drilling rig 800 first, and the drilling rig 800 and the slide rail 100 are in the same straight line, but due to the problem of installation accuracy, the drilling rig 800 and the slide rail 100 may be offset. By using cross bearings to connect the connecting frame 222 and the vehicle body 210, as well as the connecting head 221 and the connecting frame 222, it can adapt to the offset between the drilling rig 800 and the slide rail 100 to a certain extent, and ensure that the connecting head 221 can be connected to the external threaded end of the drill rod 600.

[0045] like Figure 6 and Figure 7 As shown, a placing plate 211 and a vertical plate 212 are arranged at intervals on the vehicle body 210, and a connecting frame 222 is rotatably arranged on the placing plate 211. The vertical plate 212 is used to abut against the external thread end of the drill rod 600 when the drill rod 600 is disassembled. Furthermore, the vertical plate 212 is provided with an avoidance groove for accommodating the connector 221. The avoidance groove provided on the vertical plate 212 can prevent the drill rod 600 from interfering with the vertical plate 212 when the drill rod 600 is placed on the slide rail 100; in this embodiment, the connector 221 includes a connector body and a rod body, one end of the rod body is connected to the connecting frame 222 through a cross bearing, the connector body is arranged at one end of the rod body away from the connecting frame 222, and the connector body is provided with an internal thread hole for inserting the external thread end of the drill rod 600.

[0046] like Figure 5As shown, the slide rail 100 is provided with a receiving space 110 at the bottom of the vehicle body 210, and rotating guide wheels 213 are provided at the bottom and both sides of the vehicle body 210. Guide grooves 111 are formed at the positions of the receiving space 110 corresponding to the guide wheels 213, and the guide wheels 213 are slidably arranged in the guide grooves 111. The guide wheels 213 are slidably arranged in the guide grooves 111, which can provide guidance for the sliding of the auxiliary trolley 200 and ensure the stability of the auxiliary trolley 200 when sliding; the guide grooves 111 at both sides can limit the up and down position of the auxiliary trolley 200, and the guide grooves 111 at the bottom can limit the left and right position of the auxiliary trolley 200. In this embodiment, there are multiple guide wheels 213 at the bottom and both sides of the vehicle body 210, and a connecting structure 214 connected to the chain 340 is provided on the vehicle body 210; buffer baffles 215 are provided at both ends of the vehicle body 210, and the buffer baffles 215 are used in conjunction with the buffers provided in the slide rail 100 to limit the sliding range of the auxiliary trolley 200, and a cover plate is provided at the opening of the accommodating space 110; the cover plate is used to place the drill rod 600, and can also shield the chain 340 to prevent the chain 340 from being contaminated. Further, the guide groove 111 in the accommodating space 110 is formed by the guide rod 112, and in order to simplify the structure of the slide rail 100, the number of the guide rods 112 located at the bottom is two, and the two guide wheels 213 provided at the bottom of the vehicle body 210 are slidably connected to the two guide rods 112 respectively.

[0047] like Figure 1 and Figure 2 As shown, the auxiliary device for loading and unloading drill rods 600 further includes a connecting block 500, and the slide rail 100 includes a first slide rail body 120 and a second slide rail body 130. One end of the connecting block 500 is rotatably connected to the first slide rail body 120, and the other end of the connecting block 500 is rotatably connected to the second slide rail body 130. The first slide rail body 120 and the second slide rail body 130 are connected by the connecting block 500, so that the slide rail 100 can be rotated and folded to meet the use requirements and transportation requirements of the drill rod 600; it should be noted that due to the long length of the drill rod 600, the drill rod 600 is usually required to be split during transportation to meet conventional transportation requirements, and the first slide rail body 120 and the second slide rail body 130 of the slide rail 100 of the auxiliary device for loading and unloading drill rods 600 are rotatably connected by the connecting block 500, which enables the slide rail 100 to be unfolded to meet the use requirements of the drill rod 600, and can also be rotated and folded together to meet the transportation requirements of the drill rod 600. In this embodiment, the first slide rail body 120 and the connecting block 500 as well as the second slide rail body 130 and the connecting block 500 are connected by means of bolts 431 and nuts 432. When the slide rail 100 is unfolded, the bolts 431 and nuts 432 can be tightened to fix the positions of the first slide rail body 120 and the second slide rail body 130.

[0048] The process of installing the drill rod 600 using the drill rod loading and unloading auxiliary device is as follows: first, the drill rod 600 is placed on the slide rail 100, the external thread end of the drill rod 600 is connected to the connector 221, the internal thread end of the drill rod 600 is connected to the wire rope 700 of the winch, and the internal thread end of the drill rod 600 is hoisted by the wire rope 700 of the winch. When the internal thread end of the drill rod 600 approaches the power head 810 of the drilling rig 800, the auxiliary trolley 200 is driven by the driving mechanism 300 to move toward or away from the drilling rig 800 to balance the horizontal pulling force generated when the drill rod 600 is hoisted. Align the internal threaded end of the drill rod 600 with the main shaft of the power head 810; then manually connect the internal threaded end of the drill rod 600 and the main shaft of the power head 810. After the connection is completed, remove the wire rope 700 of the winch, raise the height of the power head 810, and drive the drill rod 600 and the auxiliary trolley 200 to move until the external threaded end of the drill rod 600 is close to the drilling rig 800 (that is, when the angle between the drill rod 600 and the ground is between 70°-80°), remove the connector 221 from the external threaded end of the drill rod 600, and move away the auxiliary device for loading and unloading the drill rod to complete the installation of the drill rod 600.

[0049] The process of disassembling the drill rod 600 using the drill rod loading and unloading auxiliary device is as follows: first, lower the height of the power head 810, so that the external thread end of the drill rod 600 is placed on the body 210 of the auxiliary trolley 200, and the external thread end of the drill rod 600 is abutted against the vertical plate 212. The power head 810 continues to descend, and the auxiliary trolley 200 is pushed away from the drilling rig 800 until the angle between the drill rod 600 and the ground is about 20°. Then, the wire rope 700 of the winch is connected to the internal thread end of the drill rod 600, and the power head 810 is lowered. The internal threaded end of the drill rod 600 is removed from the power head 810. At this time, the internal threaded end of the drill rod 600 is lifted by the wire rope 700 of the winch and drives the internal threaded end of the drill rod 600 to descend until the drill rod 600 is placed on the slide rail 100, completing the disassembly of the drill rod 600. It should be noted that when the internal threaded end of the drill rod 600 is removed from the power head 810, the driving mechanism 300 can drive the auxiliary trolley 200 to move to balance the horizontal pulling force generated by the drill rod 600 and prevent the drill rod 600 from falling suddenly.

[0050] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
