Description

Technical Field

[0001] The invention relates to the field of pile foundation drilling, and more specifically, to an energy-saving highway bridge pile foundation water drilling device. Background Art

[0002] In the process of highway bridge construction, pile foundation drilling is a crucial construction link. It is directly related to the stability and safety of the bridge structure, and also affects the construction efficiency and quality. The existing pile foundation drilling equipment usually determines the drilling position, pre-buries the positioning casing, and then introduces the prepared mud for rotary drilling. However, the traditional pile foundation drilling technology has the following problems in actual operation:

[0003] Firstly, in the process of pile foundation drilling, when it is necessary to drill a pile foundation hole larger than the diameter of the drill bit, the traditional practice is to replace the drill bit with a larger diameter, which not only increases the construction cost but also prolongs the construction period, and cannot adapt to the needs of pile foundation holes of different diameters by adjusting the extension length of the steel plates on both sides under the drill rod. Secondly, after the adjustment is completed, if there is no corresponding limiting mechanism to fix the steel plate, then during the rotary drilling process, the steel plate may become loose due to vibration, resulting in deviation in the size of the pile foundation hole, thereby affecting the stability of the bridge structure. Finally, after the adjustment is completed, if the gap between the steel plate and the receiving groove is not effectively closed, then the mud generated during the drilling process may enter the receiving groove through these gaps to cause mud accumulation. The accumulation of mud will not only affect the reset of each adjustment component. In order to solve the above problems, an energy-saving highway bridge pile foundation water drilling device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0038] For examples, see Figures 1 to 13 An energy-saving highway bridge pile foundation water drilling device includes a drill rod adjustment mechanism 100, which includes a guide rail 102, and also includes a drill rod 103 arranged on one side of the guide rail 102 for drilling holes in the pile foundation. A cylinder 107 is welded below the drill rod 103, and an adjustment component for adjusting the diameter of the pile foundation hole is arranged inside the cylinder 107, and a positioning component arranged above the cylinder 107 for auxiliary positioning of the adjustment component, and a driving part arranged above the drill rod 103. Steel plates 109 are arranged on both sides of the cylinder 107, and an adjustment auxiliary mechanism 200 is arranged on one side of the cylinder 107 close to the steel plate 109. The adjustment auxiliary mechanism 200 includes a pressing component arranged inside the cylinder 107 for auxiliary pressing of the steel plate 109, and a sealing component arranged inside the cylinder 107 for sealing mud.

[0039] In this embodiment, the extension length of the steel plate 109 is adjusted by adjusting the adjustment component in the cylinder 107 below the drill rod 103 to meet the needs of pile foundation holes of different diameters, thereby avoiding the situation of replacing a large-diameter drill bit 104 and increasing the construction cost, thereby facilitating the drilling of pile foundation holes larger than the diameter of the drill bit 104. After the adjustment is completed, the positioning component is controlled to move downward so that the positioning component limits the position of the adjustment component, thereby avoiding the loosening of the adjustment component during the rotary drilling process, affecting the adjustment of the steel plate 109, and causing the size of the pile foundation hole to deviate. At the same time, during the downward movement of the positioning component , which will drive the clamping assembly to clamp and limit the two sides of the steel plate 109, preventing the steel plate 109 from loosening due to vibration, resulting in deviations in the size of the pile foundation hole, and further affecting the stability of the bridge structure, thereby further improving the stability of the steel plate 109 and ensuring the smooth drilling of the pile foundation. When the positioning assembly and the clamping assembly are in place, the sealing assemblies on the positioning assembly and the clamping assembly cooperate with each other to seal the gap between the steel plate 109 and the receiving groove, thereby preventing the mud generated during the drilling process from entering the receiving groove through the gap and causing mud accumulation, thereby facilitating the resetting of each adjustment assembly.

[0040] Specifically, the adjustment component includes a first receiving groove 108 arranged on both sides of the cylinder 107, a steel plate 109 is arranged in the first receiving groove 108, a first slide groove 110 is opened at the lower end of the first receiving groove 108, a first slider 111 is fixedly installed at the lower end of the steel plate 109, the size of the first slider 111 is adapted to the size of the first slide groove 110, and the first slider 111 is slidably connected to the first slide groove 110, a first strip groove 114 is opened on one side of the first receiving groove 108 close to the drill rod 103, a push rod 112 is arranged inside the first strip groove 114, and the push rod A wedge block 113 is provided at the lower end of 112, and the side of the steel plate 109 close to the wedge block 113 is set as an inclined surface. A second slider 115 is welded to the upper end of the push rod 112, and an adjusting disk 116 is provided above the push rod 112. An annular groove 117 is provided at the lower end of the adjusting disk 116, and the second slider 115 is slidably connected to the annular groove 117. A thread groove 118 is provided on the inner wall of the adjusting disk 116, and an external thread 120 is provided on the outer wall of the drill rod 103, and the external thread 120 is provided above the cylinder 107, and the external thread 120 is spirally connected to the thread groove 118.

[0041] In this embodiment, the wedge block 113 is fixedly connected to the push rod 112 by welding, and the edge of the steel plate 109 is set to an arc shape. The arc design of the edge of the steel plate 109 can ensure that the steel plate 109 fits the hole wall better, which helps to reduce resistance and wear during drilling and improve drilling efficiency. In addition, the curved steel plate 109 can provide better stability during drilling, which helps to maintain the straightness and directionality of the drill rod 103, thereby ensuring the quality of the pile foundation hole. In the initial state, the edge of the steel plate 109 is flush with the edge of the drill bit 104. When it is necessary to drill a pile foundation hole larger than the diameter of the drill bit 104, the adjusting disk 116 is rotated by an auxiliary tool, and the adjusting disk 116 moves upward along the external thread 120. During the upward movement of the adjusting disk 116, since the upper end of the push rod 112 is slidably connected to the adjusting disk 116, the adjusting disk 116 does not drive the push rod 112 to rotate, but drives the push rod 112 to move upward. The wedge block 113 will be driven to move along. When the wedge block 113 moves upward, it will push the inclined surface of the steel plate 109, so that the steel plate 109 moves outward, thereby adjusting the position of the steel plate 109 in the first receiving groove 108, thereby adjusting the extension length of the steel plate 109, thereby adapting to the needs of pile foundation holes of different diameters, thereby avoiding the situation of replacing a large-diameter drill bit 104 and increasing the construction cost, thereby facilitating the drilling of pile foundation holes larger than the diameter of the drill bit 104. The first slider 111 cooperates with the first slide groove 110 to ensure the stability of the horizontal movement of the steel plate 109 in the first receiving groove 108, and the external thread 120 cooperates with the thread groove 118 to control the number of adjustment circles of the adjustment disk 116, thereby ensuring the accuracy of adjusting the extension length of the steel plate 109. The second slider 115 cooperates with the annular slide groove 117 to ensure that during the rotation of the adjustment disk 116, the push rod 112 will not be driven to rotate, and the push rod 112 can only be driven to move upward or downward.

[0042] Among them, the driving part includes a power head 105 arranged above the drill rod 103, the power head 105 is slidably connected to the guide rail 102, a winch 106 is arranged on the side of the upper end of the guide rail 102 away from the drill rod 103, the winch 106 is fixedly connected to the top of the power head 105 through a steel rope, the guide rail 102 is arranged on one side of the drilling rig body 101, and a drill bit 104 is arranged below the drill rod 103.

[0043] In this embodiment, during drilling construction, the hydraulic motor in the power head 105 drives the drill rod 103 and the drill bit 104 to drill, and then the steel rope on the winch 106 cooperates with the guide rail 102 to pull the power head 105, the drill rod 103 and the drill bit 104 up and down.

[0044] Preferably, the positioning assembly includes a positioning plate 121 arranged above the cylinder 107, the diameter of the positioning plate 121 is larger than the diameter of the adjusting plate 116, a plurality of spline teeth 122 are arranged on the inner side of the positioning plate 121, and the spline teeth 122 are distributed in a ring shape, a plurality of spline grooves 119 are opened on the outer side of the adjusting plate 116, the spline teeth 122 correspond to the spline grooves 119 one by one, and the spline grooves 119 are meshed with the spline teeth 122, a screw sleeve 124 is arranged in the middle of the front end of the positioning plate 121, a screw 123 is arranged on the front side of the upper end of the cylinder 107, and the screw 123 is threadedly connected to the screw sleeve 124.

[0045] In this embodiment, after the adjustment is completed, the screw rod 123 is rotated clockwise, and the screw rod 123 cooperates with the screw rod sleeve 124 to drive the positioning disk 121 to move downward, so that the spline teeth 122 on the positioning disk 121 are stuck in the spline groove 119 on the edge of the adjusting disk 116. The spline teeth 122 cooperate with the spline groove 119 to limit the rotation position of the adjusting disk 116, thereby avoiding the vibration during the drilling process of the drill bit 104 to cause loosening of the threaded adjustment disk 116, thereby affecting the adjustment of the steel plate 109, and further avoiding the deviation of the pile foundation hole size. The screw rod 123 cooperates with the screw rod sleeve 124 to drive the positioning disk 121 to move up and down, and then when the adjusting disk 116 needs to be rotated, the positioning disk 121 can be separated from the adjusting disk 116, thereby facilitating the rotation of the adjusting disk 116.

[0046] Preferably, the clamping assembly includes a fixing rod 201 disposed below the positioning plate 121, a round rod 202 is welded to the lower end of the fixing rod 201, second receiving grooves 205 are provided on both sides of the inner cavity of the first receiving groove 108, a blocking strip 203 is provided inside the second receiving groove 205, a wedge strip 204 is provided on the side of the blocking strip 203 close to the round rod 202, a second strip groove 206 is provided at the upper end of the second receiving groove 205, the fixing rod 201 is disposed in the second strip groove 206, and the lower end of the second receiving groove 205 is provided with a sealing strip 203. A second slide groove 207 is provided on the wall, and a slide rod 208 is provided in the inner cavity of the second slide groove 207. The side of the slide rod 208 close to the blocking strip 203 is fixedly connected to the wedge strip 204. A return spring 209 is fixedly installed in the inner cavity of the second slide groove 207, and the other end of the return spring 209 is fixedly connected to the slide rod 208. A plurality of first serrated grooves 210 are provided on both sides of the steel plate 109. A second serrated groove 211 is provided on the side of the blocking strip 203 close to the steel plate 109, and the first serrated groove 210 is meshed with the second serrated groove 211.

[0047] In this embodiment, the wedge strip 204 is fixedly connected to the blocking strip 203 by welding. When the positioning plate 121 moves downward, the positioning plate 121 will drive the fixing rod 201 to move accordingly, and the round rod 202 on the fixing rod 201 will first contact the inclined surface of the wedge strip 204. When the fixing rod 201 continues to move downward, the wedge strip 204 is pushed, and the return spring 209 is stretched at the same time, so that the wedge strip 204 drives the blocking strip 203 to press against the two sides of the steel plate 109. When the round rod 202 is converted from the inclined surface of the wedge strip 204 to the vertical surface of the wedge strip 204, the fixing rod 201 that continues to move downward will no longer push the wedge strip 204, thereby ensuring that the second serrated groove 211 on the blocking strip 203 is stuck in the first serrated groove 210 of the steel plate 109, so that the steel plate The sealing strips 203 on both sides of 109 press and limit the steel plate 109, thereby limiting the horizontal position of the steel plate 109, avoiding the loosening of the steel plate 109 due to vibration, resulting in deviation in the size of the pile foundation hole, and further affecting the stability of the bridge structure, ensuring the smooth drilling of the pile foundation, and through the setting of the sliding rod 208 and the second sliding groove 207, the stability of the movement of the sealing strip 203 in the second accommodating groove 205 can be guaranteed, and then through the cooperation of the second return spring 209 in the second sliding groove 207, after the adjustment wedge strip 204 loses the downward pressure, the sealing strip 203 can be driven to separate from the steel plate 109, thereby facilitating the position adjustment operation of the steel plate 109, and through the cooperation of the fixing rod 201 and the second strip groove 206, the stability of the upward and downward movement of the positioning plate 121 can be guaranteed.

[0048] Specifically, the sealing assembly includes a first rubber frame 212 arranged on the outside of the push rod 112, a second rubber frame 213 is arranged inside the first strip groove 114, the length of the second rubber frame 213 is greater than the length of the first rubber frame 212, the first rubber frame 212 is movably connected to the second rubber frame 213, and the size of the first rubber frame 212 is adapted to the size of the second rubber frame 213, a third rubber frame 214 is arranged on the outside of the fixed rod 201, a fourth rubber frame 215 is arranged inside the second strip groove 206, the third rubber frame 214 is movably connected to the fourth rubber frame 215, and the size of the third rubber frame 214 is adapted to the size of the fourth rubber frame 215, the fourth rubber frame 215 is arranged at the lower end edge of the second strip groove 206, and the length of the fourth rubber frame 215 is greater than the length of the third rubber frame 214.

[0049] In this embodiment, when the positioning assembly and the pressing assembly are in place, the first rubber frame 212 on the pushing rod 112 will be stuck in the second rubber frame 213 inside the first strip groove 114, and the third rubber frame 214 on the fixing rod 201 will be stuck in the fourth rubber frame 215 inside the second strip groove 206, so as to achieve the blocking of the first strip groove 114 and the second strip groove 206. At the same time, because the blocking strip 203 is against both sides of the steel plate 109, the blocking strip 203 blocks the gap between the first receiving groove 108 and the steel plate 109, and the outer side of the blocking strip 203 fits with the inner wall of the second receiving groove 205, so as to avoid the mud generated during the drilling process from entering the receiving groove through the gap to cause mud accumulation, thereby facilitating the resetting of each adjusting assembly. Through the long size design of the second rubber frame 213 and the fourth rubber frame 215, it can be ensured that the pushing rod 112 and the fixing rod 201 can ensure the sticking and blocking effect at any position of the vertical movement.

[0050] When in use, in the initial state, the edge of the steel plate 109 is flush with the edge of the drill bit 104. When it is necessary to drill a pile foundation hole larger than the diameter of the drill bit 104, the adjusting disk 116 is rotated by an auxiliary tool, and the adjusting disk 116 moves upward along the external thread 120. During the upward movement of the adjusting disk 116, since the upper end of the push rod 112 is slidably connected to the adjusting disk 116, the adjusting disk 116 does not drive the push rod 112 to rotate, but drives the push rod 112 to move upward. During the upward movement of the push rod 112, the wedge block 113 will follow the movement. When the wedge block 113 moves upward, it will push the inclined surface of the steel plate 109, so that the steel plate 109 moves outward, thereby adjusting the steel plate 109 in the first receiving groove 108. The position inside the hole is adjusted to adjust the extended length of the steel plate 109, thereby adapting to the needs of pile foundation holes of different diameters, thereby avoiding the situation of replacing a large-diameter drill bit 104 and increasing the construction cost, thereby facilitating the drilling of pile foundation holes with a diameter larger than the drill bit 104. After the adjustment is completed, the screw rod 123 is rotated clockwise, and the screw rod 123 cooperates with the screw rod 123 sleeve to drive the positioning plate 121 to move downward, so that the spline teeth 122 on the positioning plate 121 are stuck in the spline groove 119 on the edge of the adjusting plate 116, thereby limiting the rotation position of the adjusting plate 116, avoiding the vibration during the drilling process of the drill bit 104 to cause loosening of the threaded adjustment plate 116, thereby affecting the adjustment of the steel plate 109, and further avoiding the size of the pile foundation hole. When the positioning plate 121 moves downward, the positioning plate 121 will drive the fixing rod 201 to move along, and the round rod 202 on the fixing rod 201 will first contact the inclined surface of the wedge strip 204. When the fixing rod 201 continues to move downward, the wedge strip 204 is pushed, and the return spring 209 is stretched at the same time, so that the wedge strip 204 drives the blocking strip 203 to press against the two sides of the steel plate 109. When the round rod 202 is converted from the inclined surface of the wedge strip 204 to the vertical surface of the wedge strip 204, the fixing rod 201 that continues to move downward will no longer push the wedge strip 204, thereby ensuring that the second serrated groove 211 on the blocking strip 203 is stuck in the first serrated groove 210 of the steel plate 109, so that the two sides of the steel plate 109 The sealing strip 203 is used to compress and limit the steel plate 109, thereby limiting the horizontal position of the steel plate 109, preventing the steel plate 109 from loosening due to vibration, resulting in deviation in the size of the pile foundation hole, and further affecting the stability of the bridge structure, ensuring the smooth drilling of the pile foundation. When the positioning assembly and the pressing assembly are in place, the first rubber frame 212 on the push rod 112 will be stuck in the second rubber frame 213 inside the first strip groove 114, and the third rubber frame 214 on the fixing rod 201 will also be stuck in the fourth rubber frame 215 inside the second strip groove 206, thereby achieving the blocking of the first strip groove 114 and the second strip groove 206. At the same time, because the sealing strip 203 is against both sides of the steel plate 109,Then, the sealing strip 203 seals the gap between the first receiving groove 108 and the steel plate 109, and the outer side of the sealing strip 203 fits with the inner wall of the second receiving groove 205, thereby preventing the mud generated during the drilling process from entering the receiving groove through the gap to cause mud accumulation, thereby facilitating the resetting of each adjustment component. During the drilling construction, the pile foundation drilling position is first determined, and then the pre-buried positioning casing is used to pass the prepared mud into the pile foundation drilling hole, and then the hydraulic motor in the power head 105 drives the drill rod 103 and the drill bit 104 to drill, and then the winch 106 cooperates with the guide rail 102 to pull the power head 105, the drill rod 103 and the drill bit 104 up and down, and then the circulating mud is discharged.
