Description

Technical Field

[0001] The invention relates to the technical field of highway bridge construction equipment, in particular to a drilling platform for highway bridge construction. Background Art

[0002] Highway bridge engineering includes the main body of the bridge (i.e. the bridge superstructure and the bridge substructure) and the ancillary engineering facilities in the overall bridge location. There are many ancillary engineering facilities, such as revetments, diversion dikes and other water flow regulating structures to maintain the stability of the river channel at the bridge location, approach bridges connecting the bridge head with the highway, railings on the bridge deck to prevent wheel collisions, sidewalk railings to ensure pedestrian safety, as well as bridge signs, navigation signs under the bridge and bridge deck lighting equipment. In addition, bridges located in earthquake zones are also equipped with earthquake-proof devices, cable-stayed bridges are equipped with additional devices to prevent wind-driven resonance on the cables, movable bridges are equipped with mechanical devices, and bridges on glacial rivers are equipped with ice-breaking devices. Therefore, bridge engineering is related to structural engineering, foundation engineering, water conservancy engineering and transportation engineering, and is related to meteorology, hydrology, engineering geology, building materials, testing technology, engineering machinery, aesthetics, environmental protection and other disciplines. It is a highly comprehensive engineering technology. In the construction process of highway bridge engineering, drilling holes in the land is one of the indispensable tasks.

[0003] However, we found in actual use that the existing drilling equipment usually uses external pressure on the drill bit plus a motor to drive the drill bit to rotate itself, thereby achieving drilling work. When drilling: the operator arrives at the designated position and starts drilling. When the depth of the spiral shaft is observed to drop to the bottom, the drill bit is slowly rotated to remove it, and then the fixed pile is placed in the hole to straighten it, and concrete is poured in. The above steps are performed. First, the operator observes to obtain the drilling depth, which is not accurate, resulting in different heights of the installed fixed piles, which in turn affects the normal installation of subsequent guardrails and other structures. Secondly, the staff straightens the fixed piles, which not only increases the workload of the operator, but also causes the fixed piles to tilt due to improper human operation, which also affects the normal installation of subsequent guardrails and other structures. For this reason, we propose a drilling platform for highway bridge construction. Summary of the invention

DETAILED DESCRIPTION

[0035] 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.

[0036] See also Figure 1-10 , the present invention provides a technical solution:

[0037] A drilling platform for highway bridge construction comprises a mounting bracket 1 mounted on one side of a concrete truck. The mounting bracket 1 is a common existing structure and will not be described in detail herein.

[0038] A lifting top plate 10 is movably provided on the mounting bracket 1, and a drilling mechanism 2 is provided on the lifting top plate 10. The drilling mechanism 2 is used to perform drilling work at a specified position and can ensure that the depth of the drilling is consistent;

[0039] The drilling mechanism 2 includes a control terminal 21 arranged on the top of the mounting bracket 1, an infrared transmitter 22 is arranged on the inner side of the top of the mounting bracket 1, and an infrared receiver 23 is arranged on the lifting top plate 10. The infrared transmitter 22 and the infrared receiver 23 are connected to the control terminal 21. When drilling, the height h of the infrared transmitter 22 above the ground and the distance a from the bottom of the drill bit 44 to the lifting top plate 10 are measured. The distance between the two is continuously measured by the infrared transmitter 22 and the infrared receiver 23, and the measured result is x, so that the drilling depth d can be calculated in real time. When d is a negative value, at this time, the drill bit 44 has not yet touched the ground, that is, the drilling has not started:

[0040] d = a + x – h;

[0041] A lifting member 3 is provided on the mounting bracket 1, and the lifting top plate 10 is connected to the lifting member 3. The lifting top plate 10 can be driven to shift radially through the lifting member 3. The lifting member 3 includes a screw rod 31 rotatably provided on the mounting bracket 1, and the top of the screw rod 31 extends to the outside of the mounting bracket 1. A first motor 32 is provided on the top of the mounting bracket 1, and the output end of the first motor 32 is connected to an end of the screw rod 31 extending to the outside of the mounting bracket 1. Guide rails 33 are provided on both sides of the mounting bracket 1. The lifting top plate 10 is threadedly connected to the screw rod 31 and is slidably provided on two guide rails 33. The first motor 32 is connected to the control terminal 21. When the infrared transmitter 22 and the infrared receiver 23 measure the target depth, the control terminal 21 controls the first motor 32 to stop working;

[0042] A drilling component 4 is provided on the lifting top plate 10, and the drilling component 4 is connected to the control terminal 21, so that the drilling work of the specified depth can be performed through the drilling component 4. The drilling component 4 includes a second motor 41 arranged on the top of the lifting top plate 10, and a rotating shaft 42 is rotatably provided at the bottom of the lifting top plate 10, and the rotating shaft 42 is connected to the output end of the second motor 41. A spiral shaft 43 is provided at the bottom of the rotating shaft 42, and a drill bit 44 is provided at the bottom of the spiral shaft 43. The second motor 41 is connected to the control terminal 21. When the infrared transmitter 22 and the infrared receiver 23 measure the target depth, the control terminal 21 controls the speed of the second motor 41 to reduce, and then the lifting component 3 can be used to achieve ascent, and when the drill bit 44 is stuck, it can rotate counterclockwise.

[0043] A pouring mechanism 5 is also provided at the bottom of the lifting top plate 10, and a fixed pile 11 is provided inside the pouring mechanism 5. After the hole drilled by the drilling mechanism 2 reaches a specified depth, the pouring mechanism 5 starts to inject concrete into the hole, and the fixed pile 11 can be directly placed in the hole during pouring. The pouring mechanism 5 includes a pouring chamber 51 provided at the bottom of the lifting top plate 10, the bottom of the pouring chamber 51 is in contact with the spiral shaft 43, a feeding pipe 52 is provided on one side of the pouring chamber 51, and a guide member 6 is provided in the pouring chamber 51, and concrete can be poured normally through the guide member 6;

[0044] A through hole 61 is provided at the top of the screw shaft 43, and the guide member 6 includes a pouring pipe 62 arranged inside the screw shaft 43. A special-shaped protrusion 63 is provided on the rotating shaft 42. The special-shaped protrusion 63 can make concrete flow smoothly into the through hole 61, wherein the pouring pipe 62 is an arc-shaped structure, which plays a certain guiding role in the placement and release of the fixed pile 11. The concrete truck starts to inject concrete into the pouring cavity 51 through the feed pipe 52. Under the action of the special-shaped protrusion 63, the concrete will better enter the pouring pipe 62 from the through hole 61 and then flow out. Since the screw shaft 43 rotates at a low speed, it can ensure that the poured concrete is relatively uniform. In addition, a water inlet pipe can be connected to the feed pipe 52, which is not shown in the figure. When drilling, a small amount of water can cool the drill bit 44, and a large amount of water can be passed after the feeding is completed, so that the feed pipe 52, the pouring cavity 51, and the pouring pipe 62 can be cleaned.

[0045] The spiral shaft 43 is a hollow structure, the fixed pile 11 is arranged inside the spiral shaft 43, and a pile setting assembly 7 is arranged on the spiral shaft 43. The fixed pile 11 can be positioned by the pile setting assembly 7, and when the drill bit 44 is taken out upward, the positioning of the fixed pile 11 is cancelled, and the pile is placed in the hole;

[0046] The pile assembly 7 includes two limit plates 71 rotatably arranged on both sides of the bottom of the spiral shaft 43. The two limit plates 71 are adsorbed by magnets, thereby limiting the fixed pile 11.

[0047] A positioning member 8 is also provided inside the rotating shaft 42, and the positioning member 8 can prevent the fixed pile 11 from shaking when the rotating shaft 42 rotates. The positioning member 8 includes a protruding column 81 provided at the center of the top inner wall of the rotating shaft 42, and a positioning tube 82 concentric with the protruding column 81 is also provided on the top inner wall of the rotating shaft 42. A plurality of springs 83 for extrusion positioning are evenly provided on the top inner wall of the rotating shaft 42, and the spring 83 is located between the protruding column 81 and the positioning tube 82;

[0048] A functional ejector 9 is arranged on the outside of the rotating shaft 42. The functional ejector 9 can separate the two limit plates 71 when the rotating shaft 42 rotates clockwise and rises, but cannot separate the two limit plates 71 when the rotating shaft 42 rotates counterclockwise. The functional ejector 9 includes two L-shaped rails 91 evenly arranged on the outside of the spiral shaft 43. Wedge blocks 92 are movably arranged in the two L-shaped rails 91. Ejector plates 93 are arranged at the bottom of the wedge blocks 92. The two ejector plates 93 are respectively in contact with adjacent limit plates 71. The L-shaped rails 91 are matched with the rotation direction of the spiral shaft 43, so that when the rotating shaft 42 rotates clockwise and rises, the two limit plates 71 can be separated, but when the rotating shaft 42 rotates counterclockwise, the two limit plates 71 cannot be separated, thereby preventing the counterclockwise rotation of the drill bit 44 after it is stuck from affecting the normal use of the limit plates 71.

[0049] An annular boss 94 is also provided between the two wedge blocks 92. When the drilling is completed, the rotation speed of the second motor 41 decreases, but the rotation direction remains unchanged. Similarly, because the friction between the annular boss 94 on the outer side of the rotating shaft and the hole wall is greater than the friction between the outer side of the spiral shaft 43 and the hole wall, the annular boss 94 will drive the wedge block 92 and the bottom ejector plate 93 to slide along the horizontal part of the L-shaped track 91 close to the vertical part until it reaches one side of the vertical part. Then, when lifting upward, the annular boss 94 will shift downward. In this process, the two ejector plates 93 will continuously squeeze the limit plate 71 downward and push the two apart. After pushing apart, due to the gravity of the fixed pile 11 itself and the action of the spring 83, the fixed pile 11 can fall directly, and as the spiral shaft 43 is continuously lifted, the fixed pile 11 gradually leaks out, and under the guidance of the perfusion pipe 62, there will be no tilt.

[0050] When in use, the operator transports the device to the designated position by a concrete truck. After reaching the designated position, the operator starts the first motor 32 to drive the screw 31 to rotate. Under the action of the guide rails 33 on both sides, the lifting top plate 10 is shifted upward. Then the operator inserts the fixed pile 11 into the screw shaft 43, so that the top of the fixed pile 11 is located between the protruding column 81 and the positioning tube 82, and squeezes the spring 83. Then, the limiting plates 71 on both sides of the bottom of the screw shaft 43 are closed, so that the limiting plates 71 are adsorbed and positioned under the action of the magnet. Then, the second motor 41 is started to drive the rotating shaft 42, the screw shaft 43 and the drill bit 44 to rotate, and the first motor 32 is started to cooperate with the descent, and then the drilling work can be carried out.

[0051] When the drill bit 44 is stuck during the drilling process, the second motor 41 is required to drive the rotating shaft 42, the spiral shaft 43 and the drill bit 44 to rotate in the opposite direction (counterclockwise). When rotating counterclockwise, the friction between the annular boss 94 on the outside of the spiral shaft 43 and the hole wall is greater than the friction between the outside of the spiral shaft 43 and the hole wall, so that the annular boss 94 will drive the wedge block 92 and the bottom ejection plate 93 to slide along the horizontal part of the L-shaped track 91 away from the vertical part, so that when the spiral shaft 43 is lifted, it will not push the limit plate 71 downward;

[0052] When drilling, the height h of the infrared transmitter 22 above the ground and the distance a from the bottom of the drill bit 44 to the lifting top plate 10 are measured. The distance between the two is continuously measured by the infrared transmitter 22 and the infrared receiver 23. The measured result is x, and the drilling depth d can be calculated in real time. When d is a negative value, the drill bit 44 has not yet touched the ground, that is, the drilling has not started:

[0053] d = a + x – h;

[0054] When the drilling is completed, the speed of the second motor 41 decreases, but the direction of rotation remains unchanged. Similarly, because the friction between the annular boss 94 on the outside of the rotating shaft and the hole wall is greater than the friction between the outside of the spiral shaft 43 and the hole wall, the annular boss 94 will drive the wedge block 92 and the bottom ejector plate 93 to slide along the horizontal part of the L-shaped track 91 close to the vertical part until it reaches one side of the vertical part. Then, when lifting upward, the annular boss 94 will move downward. In this process, the two ejector plates 93 will continuously press the limit plates 71 downward and push the two apart. After being pushed apart, due to the gravity of the fixed pile 11 itself and the action of the spring 83, the fixed pile 11 can fall directly, and as the spiral shaft 43 is continuously lifted, the fixed pile 11 gradually leaks out, and under the guidance of the perfusion pipe 62, there will be no tilting.

[0055] At the same time, the concrete truck starts to inject concrete into the pouring chamber 51 through the feed pipe 52. Under the action of the special-shaped protrusion 63, the concrete can better enter the pouring pipe 62 from the through hole 61 and then flow out. Because the spiral shaft 43 rotates at a low speed, it can ensure that the poured concrete is relatively uniform.
