DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] The purpose of the present invention is to provide a cantilever beam fixing device for horizontal drilling in a hole, which is used to solve the technical problems existing in the above-mentioned prior art. The staff only needs to hold the hand grab rod to drive the protective tube into the drill hole. It is suitable for drilling holes at various angles and has a wide range of applications.

[0060] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] Embodiment 1

[0062] like Figure 1-Figure 17 As shown, this embodiment provides a cantilever beam fixing device 100 for transverse drilling in a hole, comprising:

[0063] The protective tube 6 is a cylindrical structure with both ends closed, and a tightening device 8, a sliding device 9 and a fixing device are fixed inside the protective tube 6;

[0064] A hand grab bar 5, the hand grab bar 5 is fixed to one end of the protection tube 6, the end of the hand grab bar 5 away from the protection tube 6 is grasped by the operator, and the hand grab bar 5 is used to drive the protection tube 6 to move;

[0065] The controller 1, the tightening device 8 and the sliding device 9 are all electrically connected to the controller 1;

[0066] The tightening device 8 includes a tightening cylinder 801, a tightening double-cone disc 805 and a tightening rotating claw 804. The tightening piston rod 8013 of the tightening cylinder 801 is fixedly connected to one end of the tightening double-cone disc 805. One end of the tightening rotating claw 804 is in contact with the tightening double-cone disc 805. When the tightening double-cone disc 805 is lifted and lowered, it can drive the tightening rotating claw 804 to rotate. The tightening double-cone disc 805 can be used to drive one end of the tightening rotating claw 804 to extend out of the protective tube 6 and abut against the wall of the borehole 4.

[0067] The sliding device 9 includes a sliding cylinder 901, a sliding double-cone disc 905 and a sliding rotating claw 904. The sliding piston rod 9013 of the sliding cylinder 901 is fixedly connected to one end of the sliding double-cone disc 905. One end of the sliding rotating claw 904 is in contact with the sliding double-cone disc 905. The other end of the sliding rotating claw 904 is provided with a pulley 908. The tightening double-cone disc 805 can be used to drive the end of the tightening rotating claw 804 provided with the pulley 908 to extend out of the protective tube 6. The pulley 908 can be used to make sliding contact with the wall of the borehole 4.

[0068] The fixing device is used to fix the tool to be used, wherein the tool to be used can be a measuring device, a grinding device, or a sampling device, or other tools. In actual work, different tools to be used can be used according to different work requirements.

[0069] In actual use, the staff first installs the tool to be used on the fixing device, and then holds one end of the hand grip rod 5 to drive the protective tube 6 to move into the borehole 4. During the movement, the sliding cylinder 901 needs to be controlled to extend the sliding rotating claw 904 until the pulley 908 contacts the inner wall of the borehole 4, which can reduce the friction between the protective tube 6 and the inner wall of the borehole 4 and reduce the burden on the staff's hands. When it moves to the predetermined position, the sliding rotating claw 904 is retracted, the supporting rotating claw 804 is extended, and it is abutted against the inner wall of the borehole 4, so as to achieve the positioning of the protective tube 6. At this time, the staff can release their hands and reduce the burden on their hands. In this process, if the angle of the tool to be used is not correct, the hand grip rod 5 can also be rotated to adjust the direction of the tool to be used. After the measurement is completed, the supporting rotating claw 804 is retracted, the sliding rotating claw 904 is extended, and the pulley 908 is contacted with the inner wall of the borehole 4, so as to facilitate the pulling back of the protective tube 6.

[0070] It should be noted that the overall mass of the device is about 20 kg, so an adult can pull it. In actual applications, for some vertically downward boreholes 4, the staff needs to overcome a gravity of 20 kg when lowering or extracting upward, but this is within the tolerable range. For some horizontal boreholes 4, during the push-in and pull-out process, since the pulley 908 can provide a certain supporting force, there is no need for the staff to overcome the gravity, and the staff only needs to provide a small push-pull force. Similarly, for some inclined boreholes 4, the staff will also be more labor-saving.

[0071] In this embodiment, if Figure 1 As shown, there are two tensioning devices 8 and two sliding devices 9, and one fixing device. The specific distribution method is that the two tensioning devices 8 are fixed at the upper and lower ends of the protective tube 6, and the two sliding devices 9 are fixed at the inner wall side of the two tensioning devices 8 away from the protective tube 6, that is, the two sliding devices 9 are located at the adjacent sides of the two tensioning devices 8, and the fixing device is fixed between the two sliding devices 9.

[0072] It should be noted here that those skilled in the art can also adjust the specific number and distribution of the fixing device, the tightening device 8 and the sliding device 9 according to actual needs, and are not limited to the one in this embodiment.

Four fixed disc mounting holes 603 are provided at the upper and lower ends of the protective tube 6, and the four fixed disc first connecting holes 701 correspond to the setting positions of the four fixed disc mounting holes 603, respectively.

[0077] like Figure 4 and Figure 5As shown, the tightening support disc 802 is further provided with four tightening support disc second connection holes 8022, and the tightening connection disc 807 is provided with four tightening connection disc second connection holes 8072. The four tightening support disc second connection holes 8022 and the four tightening connection disc second connection holes 8072 are respectively fixedly connected by four tightening connection rods 806. Specifically, the two ends of the tightening connection rod 806 can be respectively fixed in the tightening support disc second connection holes 8022 and the tightening connection disc second connection holes 8072 by welding, or external threads can be respectively provided at the two ends of the tightening connection rod 806, and internal threads can be provided in the tightening support disc second connection holes 8022 and the tightening connection disc second connection holes 8072, so that the tightening connection rod 806 can be fixed by threaded connection.

Figure 5 and Fig.12 As shown, four sliding cylinder first connection holes 9011 are provided on the side of the sliding cylinder 901 away from the sliding piston rod 9013 (i.e., the bottom of the cylinder body of the sliding cylinder 901), and four tightening connection disk first connection holes 8071 are provided on the tightening connection disk 807. The distribution positions of the four sliding cylinder first connection holes 9011 correspond to the distribution positions of the four tightening connection disk first connection holes 8071. The four sliding cylinder first connection holes 9011 are respectively fixed to the four tightening connection disk first connection holes 8071 by screws, so as to realize the fixation between the sliding cylinder 901 and the tightening connection disk 807.

[0079] In addition, the sliding device 9 also includes a sliding support disc 902 and a sliding connection disc 907;

[0082] In this embodiment, if Figure 16-Figure 17 As shown, the fixing device includes two fixing members 11 and a reserved plate 10, the two fixing members 11 are respectively fixed to the upper and lower ends of the reserved plate 10, wherein the reserved plate 10 is a rectangular plate, and the fixing member 11 is a rectangular block;

[0083] Each fixing member 11 is provided with two first fixing member connection holes 1101, and the upper and lower ends of the reserved plate 10 are provided with two reserved plate connection holes 1001, respectively. The two first fixing member connection holes 1101 on each fixing member 11 are respectively connected to the two reserved plate connection holes 1001 on one end (upper end or lower end) of the reserved plate 10 by screws;

[0084] In addition, four fixing member second connecting holes 1102 are provided on the fixing member 11, and four sliding connecting disc second connecting holes 9072 are provided on the sliding connecting disc 907.

[0085] It can be understood that the upper and lower ends of the reserved plate 10 are fixed to the two sliding connection discs 907 through a fixing member 11 respectively.

[0086] When the tool to be used is actually fixed, it only needs to be placed on the sliding connection disc 907 located below, and the reserved plate 10 and the two fixing members 11 play a certain role in limiting and fixing. Of course, those skilled in the art can also change the shape of the reserved plate 10 according to actual needs to enhance its limiting effect on the tool to be used. Of course, those skilled in the art can also enhance other structures to directly fix the tool to be used on the reserved plate 10.

Specifically, a hinge shaft is used to pass through both sides of the hinge groove and the corner of the tightening rotating claw 804 at the same time, so as to realize the rotation connection between the tightening rotating claw 804 and the tightening clamp 803;

[0088] Similarly, if Fig.14 As shown, three sliding clamps 903 are fixed on the sliding support disc 902. The structure and distribution of the three sliding clamps 903 are the same as those of the tightening clamps 803. They are also located at the three vertices of the triangle and have hinge grooves. There are three sliding rotating claws 904. The sliding rotating claws 904 are L-shaped structures. The corners of the sliding rotating claws 904 are hinged to one end of the sliding clamp 903 away from the sliding support disc 902 (i.e., the hinge groove), thereby realizing the rotational connection between the sliding rotating claws 904 and the sliding clamp 903.

[0089] In this embodiment, if Fig. 9 As shown, the tightening double cone disc 805 includes a tightening large cone disc 8051 and a tightening small cone disc 8052. The maximum diameter of the tightening large cone disc 8051 is greater than the maximum diameter of the tightening small cone disc 8052. The tip of the tightening large cone disc 8051 is fixedly connected to the tip of the tightening small cone disc 8052. The end of the tightening small cone disc 8052 away from the tightening large cone disc 8051 is fixedly connected to the tightening piston rod 8013. Specifically, an internal thread can be provided on the end of the tightening small cone disc 8052 away from the tightening large cone disc 8051, and an external thread can be provided on the end of the tightening piston rod 8013, so that the two are connected and fixed by threads.

[0090] The two ends of the tightening rotating claw 804 are respectively a tightening rotating active end 8041 and a tightening rotating driven end 8042 . The tightening rotating active end 8041 abuts against the connection between the tightening large cone disk 8051 and the tightening small cone disk 8052 , and the tightening rotating driven end 8042 can extend out of the protective tube 6 .

[0091] by Fig. 9For example, in actual use, when the tightening double cone disc 805 moves upward, the tightening double cone disc 805 will push the tightening rotation active end 8041 upward, thereby driving the tightening rotation claw 804 to rotate in the opposite direction, and finally making the tightening rotation driven end 8042 extend from the left side of the protection tube 6 and abut against the inner wall of the borehole 4. When it is necessary to retract it, it is only necessary to drive the tightening double cone disc 805 downward through the tightening cylinder 801, and the tightening large cone disc 8051 can drive the tightening rotation active end 8041 to move downward, so that the tightening rotation active end 8041 is retracted. The reason why the tightening large cone disc 8051 is set to have a larger diameter and a shorter height is because it is convenient to retract the already extended tightening rotation claw 804.

[0092] Similarly, Fig.15 As shown, the structure of the sliding double cone disk 905 is the same as that of the tightening double cone disk 805. The sliding double cone disk 905 includes a sliding large cone disk 9051 and a sliding small cone disk 9052. The tip of the sliding large cone disk 9051 is fixedly connected to the tip of the sliding small cone disk 9052. The end of the sliding small cone disk 9052 away from the sliding large cone disk 9051 is fixedly connected to the sliding piston rod 9013. The sliding small cone disk 9052 and the sliding piston rod 9013 are also connected by threads.

[0093] The two ends of the sliding rotating claw 904 are respectively a sliding rotating active end 9041 and a sliding rotating driven end 9042. The sliding rotating active end 9041 abuts against the connection between the sliding large cone disk 9051 and the sliding small cone disk 9052. The sliding rotating driven end 9042 can extend out of the protective tube 6. Unlike the tightening rotating claw 804, the pulley 908 is arranged on the sliding rotating driven end 9042. When the sliding rotating driven end 9042 extends out, the pulley 908 abuts against the inner wall of the borehole 4, thereby facilitating the movement of the protective tube 6 in the borehole 4. The rotation principle is the same as that of the tightening rotating claw 804, and no further description is given here.

[0094] In this embodiment, if Figure 2 As shown, the protective tube 6 is provided with a cable through hole 601, a plurality of tensioning device through holes 604 and a plurality of sliding device through holes 605. Among them, the cable through hole 601 is located at the upper end of the protective tube 6, and the cable through hole 601 is used for each connecting wire to pass through, which is convenient for circuit connection. One end of the tensioning rotating claw 804 can pass through the tensioning device through hole 604, and the number of the tensioning device through holes 604 is the same as that of the tensioning rotating claw 804 and corresponds one to one. Similarly, the pulley 908 on the sliding rotating claw 904 can pass through the sliding device through hole 605, and the number of the sliding device through holes 605 is the same as that of the sliding rotating claw 904 and corresponds one to one.

[0095] It should be noted that the through hole 604 of the tensioning device and the through hole 605 of the sliding device are both oblong holes, and their length is greater than the diameter of the tensioning rotating driven end 8042 or the sliding rotating driven end 9042. The purpose of this arrangement is to prevent the tensioning rotating driven end 8042 or the sliding rotating driven end 9042 from getting stuck on the inner wall of the protective tube 6 when rotating outward.

[0096] In this embodiment, the hand grab bar 5 includes a plurality of hand grab short bars, each of which is about 1m long, one end of the hand grab short bar is provided with a short bar external thread, and the other end of the hand grab short bar is provided with a short bar internal thread hole. The short bar internal thread hole on one hand grab short bar can be threadedly connected with the short bar external thread on the adjacent hand grab short bar. It can be understood that the hand grab bar 5 is formed by connecting a plurality of hand grab short bars end to end in sequence.

[0097] like Figure 2 As shown, the protection tube 6 is provided with a hand grab bar connection hole 602 , and the hand grab bar connection hole 602 is provided with an internal thread, and a short rod external thread of a hand grab bar can be threadedly connected with the hand grab bar connection hole 602 .

[0098] In actual use, a small number of hand-grip short rods are first connected end to end in sequence, and the hand-grip short rods at the ends are fixed to the protective tube 6. Then the protective tube 6 is slowly inserted into the borehole 4. When the hand-grip rod 5 is not long enough, several more hand-grip short rods can be connected to the hand-grip short rods located outside the borehole 4 until the hand-grip rod 5 is long enough to send the tool to be used to the expected position.

[0099] In addition, the hand grip bar 5 may be replaced by a telescopic bar, such as an electric telescopic bar, a hydraulic cylinder or a pneumatic cylinder commonly available on the market.

[0100] In this embodiment, each of the tightening cylinder 801 and the sliding cylinder 901 is provided with two air holes, and the two air holes are respectively connected to a pneumatic solenoid valve 2 through an air pipe, and the air inlet of the pneumatic solenoid valve 2 is connected to an air pump 3 through a pipeline, and the pneumatic solenoid valve 2 is electrically connected to the controller 1. The operation of the pneumatic solenoid valve 2 can be controlled by the controller 1, thereby controlling the air inlet or outlet of the two air holes on the tightening cylinder 801 or the sliding cylinder 901. Since there are two tightening cylinders 801 and two sliding cylinders 901 in total, there are four pneumatic solenoid valves 2 and four air pumps 3 respectively, and the four pneumatic solenoid valves 2 are all electrically connected to the controller 1 and are uniformly controlled by the controller 1.
