After the drill arm is retracted to a set angle, it can smoothly pass through the hoisting tray facilities in the well. Whether it is a forward well or a reverse well construction, it can be used without obstacles.

[0057] The station anchoring adopts the method of hydraulic four movable legs and double column top and bottom support, which has simple anchoring process, high efficiency and stable anchoring;

[0058] By extending and retracting the No. 4 hydraulic rod 38, the extension rod 37 can be pushed to allow the turntable 36 to freely rotate at an angle of 30° to the left and right of its own axis, greatly improving the free adjustment range of the drilling assembly 4; it can also reduce mutual interference caused by drilling direction or position when two rods 4 are working at the same time.

[0064] The equipment is equipped with a hydraulic pump station and hydraulic rods to achieve all-round angular adjustment of the drilling hole, and cooperates with the drilling measurement system to achieve directional and controllable drilling of the equipment.

[0065] Example 2

[0066] like Figure 6 to Figure 8 As shown, on the basis of Example 1, it is further proposed that the reinforcement structure 8 includes a support plate 81 that is arranged between the adjustment bracket 33 and the main bracket 32, a through hole 82 is opened on the surface of the support plate 81, and a positioning ring 83 is arranged on the inner side of the adjustment bracket 33 near both sides of the support plate 81, a fixing column 84 is fixedly connected between the positioning ring 83 and the inner side of the adjustment bracket 33, a telescopic cylinder 85 is fixedly connected to the surface of the adjustment bracket 33 corresponding to the center of the positioning ring 83, and an insertion rod 86 is fixedly connected to the output end of the telescopic cylinder 85.

[0067] The support plate 81 and the main bracket 32 ​​are welded and fixed, and the support plate 81 and the adjusting bracket 33 are slidably connected. The number of through holes 82 is several groups and distributed in a ring array. The positioning ring 83 is a hollow circular ring structure. There are several groups of fixing columns 84 between the positioning ring 83 and the adjusting bracket 33. The diameter of the insertion rod 86 is equal to the inner diameter of the positioning ring 83 and the aperture size of the through hole 82. The telescopic cylinder 85 extends and pushes the insertion rod 86 to be stuck into the two groups of positioning rings 83 and the inside of the through hole 82 to enhance the supporting performance between the adjusting bracket 33 and the main bracket 32.

[0068] In this embodiment, during use, the adjustment bracket 33 can be stretched out on the surface of the main bracket 32, while maintaining the stability of the rotation and expansion between the adjustment bracket 33 and the main bracket 32, which has a reinforcing effect and can effectively reduce the jacking pressure of the second hydraulic rod 35, thereby effectively improving the service life of the equipment.

[0069] Example 3

[0070] like Figures 9 to 11 As shown, on the basis of Example 1, a positioning structure 9 is proposed, which includes a main box 91 and a sub-box 92 which are respectively slidably sleeved on the surface of the hydraulic rock drilling rod 42 and the rock rod support 41, and a No. 3 hydraulic rod 93 is hingedly connected to the same cross-section on the inner side of the main box 91 and the sub-box 92, and a frame 94 is hingedly connected between the ends of the two groups of No. 3 hydraulic rods 93 on the same cross-section, and a universal ball 95 is fixedly connected to the outer surface of the frame 94, and a noise reduction plate 96 is fixedly connected between the inner sides of the main box 91 and the sub-box 92.

[0071] The main box 91 and the auxiliary box 92 are slidably connected to each other, and the main box 91 and the auxiliary box 92 are slidably connected to the rock rod support 41 and the hydraulic rock drilling rod 42, and the end of the No. 3 hydraulic rod 93 away from the output is fixedly connected to the rock rod support 41 through the support. The number of No. 3 hydraulic rods 93 is two groups and they are symmetrically distributed. The two groups of No. 3 hydraulic rods 93 respectively drive the main box 91 and the auxiliary box 92 to move away from or close to each other, and the universal ball 95 supports and positions the hydraulic rock drilling rod 42 through the mutual approach of the main box 91 and the auxiliary box 92. Electronic tag identifiers are respectively provided on the surface of the rock rod support 41. The electronic tag identifiers have depth and angle sensors, and the electronic tag identifiers are used to correct the drilling trajectory.

[0072] One end of the auxiliary box 92 is matched with the main box 91, a metal plate is provided in the middle of the noise reduction plate 96, and elastic sponges are adhered to both sides of the metal plate. When the No. 3 hydraulic rod 93 is extended to the maximum, the main box 91 and the auxiliary box 92 are away from each other to the maximum distance, and the noise reduction plate 96 is an unfolded straight structure. When the No. 3 hydraulic rod 93 is retracted to the minimum position, the auxiliary box 92 is embedded in the main box 91, and the noise reduction plate 96 is a raised arc structure.

[0073] In this embodiment, during use, the position of the hydraulic rock drilling rod 42 can be positioned, fixed, and guided by the universal ball 95, which can reduce the slight offset of the hydraulic rock drilling rod 42 after long-term use. At the same time, the force of the universal ball 95 squeezing the hydraulic rock drilling rod 42 can be adjusted by contracting the No. 3 hydraulic rod 93. At the same time, the curvature of the noise reduction plate 96 can be increased, thereby reducing the operating noise of the hydraulic rock drilling rod 42.

[0074] The present invention also includes a construction method of a drilling and blasting trolley for a large-section deep shaft, and the construction method includes the following contents:

[0075] Step 1: Positioning and drilling; the main support 32 is rotated to a suitable angle by pushing the No. 1 hydraulic rod 34, and the adjustment support 33 is rotated to a suitable angle by pushing the No. 2 hydraulic rod 35, so that the outer end of the hydraulic drilling rod 42 is tilted to correspond to the hole position marked on the inner side of the shaft, and the drilling assembly 4 is started to make the outer end of the hydraulic drilling rod 42 drill a hole until the drilling reaches the designed depth;

[0076] Step 2: Slag removal, cleaning and hole formation; water injection for cleaning is performed while drilling, and water is continuously injected after drilling is completed to remove slag, and holes are formed after the discharged water flow becomes clean water.

[0077] In summary, the working principle of the present invention is as follows:

[0078] During use, first positioning and drilling are performed; the main support 32 is rotated to a suitable angle by pushing the No. 1 hydraulic rod 34, and the adjustment support 33 is rotated to a suitable angle by pushing the No. 2 hydraulic rod 35, so that the outer end of the hydraulic rock drilling rod 42 is tilted to correspond to the hole position marked on the inner side of the shaft, and the drilling assembly 4 is started, so that the outer end of the hydraulic rock drilling rod 42 is used to drill a hole until the drilling reaches the designed depth;

[0079] After that, the slag is removed, cleaned and holes are formed; water is injected for cleaning while drilling, and water is continuously injected after the drilling is completed to remove the slag, and holes are formed after the discharged water flow becomes clean water.

[0080] During the above-mentioned use, when the adjusting bracket 33 is unfolded to a suitable angle at one end of the main bracket 32 ​​and it is necessary to maintain the current posture for drilling, the output end of the telescopic cylinder 85 can be extended so that one end of the insertion rod 86 passes through the inside of a group of positioning rings 83, and then passes through the through hole 82 on the surface of the support plate 81, and then passes through the inside of another group of positioning rings 83. The two groups of positioning rings 83 are connected to the support plate 81 through the insertion rod 86, so that a better and more stable supporting force is obtained between the adjusting bracket 33 and the main bracket 32, effectively maintaining the performance of the equipment for long-term use, and at the same time, the reaction force of the No. 2 hydraulic rod 35 when the drilling assembly 4 is drilling can be reduced, thereby extending the service life of the equipment.

[0081] During the drilling process, the No. 3 hydraulic rod 93 can be retracted, and the main box 91 and the auxiliary box 92 will approach each other until the main box 91 and the auxiliary box 92 are interlocked with each other. During this process, the inclination angle of the No. 3 hydraulic rod 93 on the same cross section will increase until the surface of the universal ball 95 directly forms a point contact state with the surface of the hydraulic rock drilling rod 42. At the same time, the noise reduction plate 96 will change from a straight state to a curved state. During the drilling process of the hydraulic rock drilling rod 42, the universal ball 95 supports and guides the drilling position of the hydraulic rock drilling rod 42, so that on the basis of the original rock rod support 41, the hydraulic rock drilling rod 42 can be further maintained without generating any vibration when running. The axial offset is generated to achieve the effect of precise positioning, which greatly reduces the error in the drilling process. According to the arc angle of the noise reduction plate 96, the noise transmitted to the outside during the operation of the hydraulic rock drill rod 42 can be effectively suppressed. According to the adjustment of the distance between the main box 91 and the auxiliary box 92, when the main box 91 and the auxiliary box 92 are far away from each other, the noise reduction plate 96 is in a straight state. At this time, the noise reduction effect is minimal, and when the main box 91 and the auxiliary box 92 are in the engaged state, the noise reduction plate 96 will be in an arc structure. At this time, the sponge structure on both sides of the noise reduction plate 96 can be fully exposed, and effectively suppress the noise of the hydraulic rock drill rod 42 during rotation drilling, thereby suppressing the noise.

[0082] It should be noted that compared with the original pneumatic rock drilling machinery and equipment used in shaft excavation, this new equipment has significant advantages such as energy saving, high efficiency, low cost and good working conditions due to its full hydraulic drive. According to the requirements of the drilling arrangement of shaft excavation, the slot holes, auxiliary holes and peripheral holes of the excavation section can be fully adapted to the drilling; in addition, the drilling of anchor holes that take up a long time when supporting the shaft wall is used to maximize the superior performance of the machinery. Its drilling speed is generally 50-100% higher than that of pneumatic equipment (comparison: the drilling speed of a manually operated hand pneumatic drill is 0.25m / min (aperture 32-42mm); the drilling speed of this type of equipment is 1.5m / min (aperture 50mm), and there is no obvious attenuation of the hole-forming efficiency when the aperture reaches 60mm), and the energy consumption is one-third of that of wind (gas) drive; it can also adjust the oil volume, pressure and piston stroke according to the hardness of the surrounding rock, greatly improving the rock drilling efficiency.

[0083] Compared with wind (gas) driven drilling equipment, it does not emit oil mist and harmful gases during construction, and also has the advantages of low power consumption, high energy utilization, high rock drilling efficiency, and no exhaust noise.

[0084] The development and use of this equipment can truly realize the functions of automatic hole opening, automatic shutdown, automatic drill withdrawal, drill jam prevention, automatic shifting and positioning of the trolley and drill arm, and remote control operation system. It is used to drill rock holes with a diameter of 20 to 100 mm and a depth of less than 20 meters in medium-hard rocks.

[0085] In addition, in order to meet the needs of various special wellbore construction, this type of equipment is also developing in the direction of large-scale and miniaturization; and implanting three-dimensional digital applications, progress visualization control technology and procedures, greatly improving the level of safety control, dynamic quality tracking and other refinements of on-site construction.

[0086] The noise sound pressure level generated by the equipment may be close to 100dB (A), and the sound energy is concentrated in the 1kHz-5kHz frequency range, which is still within the sensitive frequency range of the human ear. If noise protection measures are not taken, it will still be harmful to the health of construction workers. The sound sources mainly include the noise generated by the impact mechanism, the noise generated by the rotary mechanism, and the noise generated by the drill bit breaking the rock. The noise is mainly caused by structural noise. The structural gap of the hydraulic rock drill, the accumulator parameters, the characteristics of the impact material, and the tightness of the connecting parts are all factors that affect the noise of the hydraulic rock drill. To reduce the noise generated, a variety of measures should be taken to obtain greater improvement. Through the joint action of the various structures of the positioning structure 9 of the present invention, the noise can be effectively suppressed.

[0087] It should be noted that, in the present invention:

[0088] The upper part of the crawler chassis 1 is connected to a gear turntable structure consisting of a driven gear A, a driving gear B, and a rotating motor C, and the drill arm base 2 of the driving structure 3 is connected to the driving end of the gear disk, and the drill arm base 2 can realize 360-degree arbitrary rotation;

[0089] By extending and retracting the No. 4 hydraulic rod 38, the extension rod 37 can be pushed to allow the turntable 36 to freely rotate at an angle of 30° to the left and right of its own axis, greatly improving the free adjustment range of the drilling assembly 4; it can also reduce the mutual interference caused by the drilling direction or position when the two drilling assemblies 4 are working at the same time;

[0090] All hinges are hydraulically driven, making them highly adaptable in any space.

[0091] All actions of this type of machine are mechanized and can be completed by personnel operating the micro host terminal;

[0092] This type of machine should have both diesel engine and external power supply;

[0093] The present invention is committed to developing and putting into use a drilling and blasting trolley applicable to various industries and various types of vertical shaft operations, and is committed to realizing the vertical shaft drilling and blasting operations entering a higher intelligent mechanization era.

[0094] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
