Description

Technical Field

[0001] The utility model relates to the technical field of arch crown void grouting, and particularly relates to a rotatable and liftable grouting hole drilling device. Background Technique

[0002] During the construction of arch wall lining, due to reasons such as concrete cooling and shrinkage, voids are likely to occur at the arch crown. Grouting with formwork cannot completely solve the void problem. Generally, impact drills are used to drill holes and grout for arch crown void grouting. However, due to upward drilling, the manual operation efficiency is low, and the waterproof board is easily damaged, and the grouting effect is not ideal. Content of the Utility Model

[0003] To solve the above technical problems, the utility model proposes a rotatable and liftable grouting hole drilling device.

[0004] The technical solution of the utility model is realized as follows:

[0005] A rotatable and liftable grouting hole drilling device includes a fixed tray and a liftable drilling rig. Legs are arranged at the four corners of the bottom of the fixed tray. The liftable drilling rig includes a lifting slide and a drilling rig. The drilling rig is detachably installed on the lifting slide. A grouting sleeve is rotatably installed on the top of the fixed tray. The slide is slidably sleeved on the grouting sleeve, and a scale is arranged on the grouting sleeve. A drilling rig height adjusting component is arranged between the lifting slide and the grouting sleeve.

[0006] Further, two right-angled rulers distributed relatively are arranged on the top of the fixed tray. Upper threaded sleeves and lower threaded sleeves distributed vertically are arranged on both sides of the grouting sleeve. The upper threaded sleeve is rotatably inserted into the right-angled ruler, and the lower threaded sleeve is inserted into the arc-shaped groove of the right-angled ruler. An upper mounting bolt and a lower locking bolt are respectively threadedly connected to the upper threaded sleeve and the lower threaded sleeve.

[0007] Further, a grouting hose is connected to the bottom end of the grouting sleeve. A strip-shaped channel is opened on the fixed tray, and the bottom end of the grouting hose passes through the strip-shaped channel and penetrates the fixed tray.

[0008] Further, the drilling rig height adjusting component includes a rack, a gear and an operating rod. The rack is fixedly installed on the surface of the grouting sleeve. The gear is rotatably installed on the lifting slide through a rotating shaft. The gear meshes with the rack. Both ends of the rotating shaft penetrate the lifting slide and are connected to the operating rod.

[0009] Further, through holes are opened at both ends of the rotating shaft, and the operating rod penetrates the through holes.

[0010] Furthermore, a limiting plate is slidably sleeved on the lifting sliding seat. A locking tooth block is arranged on one side of the limiting plate and located on the rack. A pull rod is fixedly installed on the outer side surface of the locking tooth block, and a spring is arranged between the pull rod and the limiting plate.

[0011] The utility model has the following beneficial effects:

[0012] 1. During the construction of dealing with the void behind the tunnel vault and the primary support, the traditional construction process requires 3 workers to cooperate in construction, while the rotatable and liftable grouting hole drilling device of the present application can be operated by only 1 person, greatly saving the labor input cost.

[0013] 2. Compared with the traditional impact drill for drilling, the rotatable and liftable grouting hole drilling device of the present application reduces the construction time and ensures the quality of the waterproof board and the quality of void grouting. Description of the Drawings

[0020] Next, the technical solutions in the embodiments of the utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0021] As Figures 1 to 5 shown, a rotatable and liftable grouting hole drilling device includes a fixed tray 1 and a liftable drilling rig 3. Legs are provided at the four corners of the bottom of the fixed tray 1. The liftable drilling rig 3 includes a lifting slide 2 and a drilling rig 3. The drilling rig 3 is detachably installed on the lifting slide 2. A grouting sleeve 4 is rotatably installed on the top of the fixed tray 1. The slide is slidably sleeved on the grouting sleeve 4, and a scale 5 is provided on the grouting sleeve 4. A drilling rig height adjusting member 6 is provided between the lifting slide 2 and the grouting sleeve 4.

[0022] When applying the rotatable and liftable grouting hole drilling device of this embodiment, first use non-destructive testing methods such as secondary lining radar monitoring to determine the defect position and depth of the tunnel lining. Then fix the drilling device on the arch trolley through the fixed tray 1. After that, shake the operating rod 6.3, use the lifting slide 2 to lift and lower the drilling rig 3 to the lining surface. According to the defect depth value monitored by the radar, compare with the scale 5 to accurately control the drilling depth to the lining defect position. When the drilling depth is 2 - 3 centimeters away from the defect depth, slow down the drilling speed to prevent damage to the lining waterproof layer.

[0023] When the lining defect position is at the waist position of the arch, the angle of the drilling rig 3 can be adjusted by rotating the grouting sleeve 4 on the fixed tray 1 for drilling.

[0024] After the drilling is completed, prepare the slurry for grouting to complete the defect rectification. Later, conduct radar detection on the defect position again, and the compactness behind the lining can reach 100%.

[0025] Among them, two relatively distributed angle irons 7 are provided on the top of the fixed tray 1. Upper threaded sleeves 8 and lower threaded sleeves 9 are provided on both sides of the grouting sleeve 4 in an up-and-down distribution. The upper threaded sleeve 8 can be rotatably inserted into the angle iron 7, and the lower threaded sleeve 9 is inserted into the arc groove of the angle iron 7. The upper threaded sleeve 8 and the lower threaded sleeve 9 are respectively threadedly connected with an upper mounting bolt 10 and a lower locking bolt 11.

[0026] The grouting sleeve 4 is supported on the fixed tray 1 by the angle irons 7 on both sides, and the grouting sleeve 4 can rotate around the upper threaded sleeve 8 as the center. When the grouting sleeve 4 rotates to a suitable angle, the grouting sleeve 4 is fixed by tightening the lower locking bolt 11.

[0027] The bottom end of the grouting sleeve 4 is connected with a grouting hose 12. A strip-shaped channel 13 is opened on the fixed tray 1. The bottom end of the grouting hose 12 passes through the fixed tray 1 through the strip-shaped channel 13. The grouting hose 12 is used to connect to an external slurry supply device. In addition, when the grouting sleeve 4 rotates, the grouting hose 12 swings in the strip-shaped channel 13 and will not be bent or extruded and deformed, thus ensuring effective grouting operations at different angles.

[0028] The drill height adjustment component 6 includes a rack 6.1, a gear 6.2 and an operating rod 6.3. The rack 6.1 is fixedly installed on the surface of the grouting sleeve 4. The gear 6.2 is rotatably installed on the lifting slide 2 through a rotating shaft. The gear 6.2 meshes with the rack 6.1. Both ends of the rotating shaft penetrate through the lifting slide 2 and are connected to the operating rod 6.3.

[0029] When rotating the operating rod 6.3, the operating rod 6.3 drives the gear 6.2 to rotate through the rotating shaft. The gear 6.2 rolls on the rack 6.1, thereby realizing the lifting operation of the drill 3.

[0030] Through holes are provided at both ends of the rotating shaft, and the operating rod 6.3 penetrates through the through holes. By sliding the operating rod 6.3 inward, when rotating the operating rod 6.3, by pulling the operating rod 6.3 towards the hand side, the force arm is extended, making the lifting control of the drill 3 more labor-saving.

[0031] A limiting plate 14 is slidably sleeved on the lifting slide 2. A locking tooth block 15 is provided on one side of the limiting plate 14 facing the rack 6.1. A pull rod 16 is fixedly installed on the outer side surface of the locking tooth block 15, and a spring 17 is provided between the pull rod 16 and the limiting plate 14. The elastic force of the spring 17 enables the locking tooth block 15 to stably engage with the rack 6.1. By pulling the pull rod 16 outward, the spring 17 is compressed, and the locking tooth block 15 displaces outward and separates from the rack 6.1. Before using this device to drill holes, first compare the scale 5 according to the defect depth value detected by the radar. Move the limiting plate 14 on the grouting sleeve 4 so that the scale on the scale 5 corresponding to the bottom of the limiting plate 14 corresponds to the scale corresponding to the drill 3 when drilling to the required deepest distance, thereby being able to limit the highest position of the drill 3 and prevent the occurrence of over-drilling.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
