Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering detection, in particular to a bridge engineering detection and exploration device. Background Technique

[0002] Bridge engineering refers to the working process of bridge survey, design, construction, maintenance and verification, etc. Bridge engineering mainly studies bridge crossing design, determines the bridge aperture, considers navigation and line requirements to determine the deck height, considers that the foundation is not scoured or frost-heaved to determine the foundation embedment depth, designs diversion structures, etc. During the bridge construction process, it is necessary to detect and explore the rock and soil. The purpose of rock and soil exploration is to estimate and evaluate the bridge engineering design and the prevention and control engineering of the stability of bridge use, so as to meet the requirements of safe bridge engineering design.

[0003] Existing rock and soil exploration requires drilling. The commonly used tool for drilling is a drilling machine. The drilling machine generally consists of a driving motor, a drill pipe, a bracket and a mechanism for assisting the up and down movement of the drill pipe.

As the penetration depth increases, different rock and soil layers can be contacted. After the drill pipe is removed from the soil surface, the rock and soil attached to the drill pipe and the length of the soil imprint can be measured, so that bridge construction personnel can know the characteristics of the rock and soil quality at different depths and ensure the safe progress of bridge construction. However, during the use of the drilling machine, the drilling machine and the moving mechanism are only connected by a single connecting rod.

[0023] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The stabilizing component includes: a fixed block 2, a stabilizing rod 201, a slider 202, a chute a 203, a slide rod 204, and a support plate 205. A buffer component is provided at the outer end of the square cylinder 101. The buffer component includes: a circular cylinder 4, a movable hole 401, a damper 402, and a spring 403.

[0026] Wherein, wing plates 5 are welded on both sides of the outer end of the device support 1. Threaded holes 501 are opened on both sides of the top of the wing plates 5. An adjusting screw rod 502 is threadedly connected inside the threaded holes 501. A handwheel 503 is fixedly installed at the top of the adjusting screw rod 502.

[0027] When the device support 1 is placed in the exploration area for use, the device support 1 supports and places the square cylinder 101, the chassis 102, the drilling motor 103, and the drill pipe 104. At this time, hold the handwheel 503 and rotate the adjusting screw rod 502 clockwise. The adjusting screw rod 502 rotates threadedly inside the threaded hole 501, so that the adjusting screw rod 502 moves towards the ground soil layer. Since the bottom end of the adjusting screw rod 502 is provided with a tapered structure, when the bottom end of the adjusting screw rod 502 contacts the ground, continuously rotate the adjusting screw rod 502 and turn the adjusting screw rod 502 into the soil layer until the handwheel 503 fits the surface of the wing plate 5, thereby stably placing the device support 1 and preventing the device support 1 from shifting and affecting the normal use of the exploration device.

[0028] Wherein, a stepping motor 105 is fixedly installed at the top end of the square cylinder 101. A reciprocating lead screw 106 connected to the driving end of the stepping motor 105 is arranged inside the square cylinder 101, and the reciprocating lead screw 106 is rotatably connected to the bottom end inside the square cylinder 101 through a bearing. A connecting rod 107 is installed at the outer end of the chassis 102. A moving block 108 is arranged on the reciprocating lead screw 106. A threaded hole threadedly connected to the reciprocating lead screw 106 is opened inside the moving block 108. A moving groove 109 is opened on the outside of the square cylinder 101, and the connecting rod 107 passes through the moving groove 109 and is fixedly connected to the moving block 108. A through hole 110 aligned with the drill pipe 104 is opened at the top of the device support 1.

[0029] After fixing the equipment support 1 to the exploration area, start the stepping motor 105 and the drilling motor 103. The drilling motor 103 drives the drill rod 104 to rotate, and the stepping motor 105 drives the reciprocating lead screw 106 to rotate. Since the threaded hole inside the moving block 108 is in threaded rotation with the reciprocating lead screw 106, and the connecting rod 107 passes through the moving groove 109 and is fixedly connected to the moving block 108. At this time, when the moving block 108 moves downward, it will drive the connecting rod 107, the chassis 102, the drilling motor 103 and the drill rod 104 to move downward, so that the drill rod 104 penetrates through the through hole 110 and moves towards the ground and drills into the soil layer. The stepping motor 105 and the drilling motor 103 respectively drive the reciprocating lead screw 106 and the drill rod 104 to work continuously, so that the drill rod 104 can drill into rock and soil layers at different depths. After the drill rod 104 is removed from the soil surface, the rock and soil attached to the drill rod 104 and the length of the soil imprint can be measured to complete the exploration work for bridge construction, facilitating bridge construction personnel to know the characteristics of the rock and soil quality at different depths and ensuring the safe progress of bridge construction.

[0030] When the reciprocating lead screw 106 rotates inside the square barrel 101, the reciprocating lead screw 106 is rotatably connected to the bottom end inside the square barrel 101 through a bearing, ensuring the normal operation of the reciprocating lead screw 106 while also preventing wear between the reciprocating lead screw 106 and the bottom end inside the square barrel 101.

[0031] Among them, an electric control box is installed on the outer end of the equipment support 1. The stepping motor 105 and the drilling motor 103 are respectively connected to the electric control box through wires. A power cord is installed on the back of the electric control box, and the length of the power cord is 5 meters. One end of the power cord is installed with a plug. Most existing bridge construction operations are carried out outdoors using diesel generators to store the generated electrical energy in a storage battery. The plug can be inserted into the power connection socket of the storage battery to supply power to the electric control box, the stepping motor 105 and the drilling motor 103 through the storage battery, and the electric control box can control the start and stop of the stepping motor 105 and the drilling motor 103. The forward rotation button and the reverse rotation button provided inside the electric control box can control the forward and reverse rotation of the stepping motor 105. And for the control program involved in the present utility model, those skilled in the art can all be realized according to the same or similar principles in the prior art. This part is not the innovation of the present utility model.

[0032] Among them, a plug board 207 is installed at the bottom of the support plate 205, and mounting blocks a 208 are respectively installed on both sides of the bottom of the support plate 205. A slot 3 for plugging and fixing with the plug board 207 is opened at the top of the equipment support 1. When the support plate 205 is in use, the plug board 207 at the bottom of the support plate 205 is inserted into the slot 3 at the top of the equipment support 1, so that the plug board 207 is plugged and fixed with the slot 3. After the plug board 207 is completely inserted into the slot 3, the mounting blocks a 208 on both sides of the bottom of the support plate 205 are attached to the top surface of the equipment support 1. Corresponding mounting screw holes are opened on both the mounting block a 208 and the top surface of the equipment support 1, and the support plate 205 can be fixed by tightening bolts in the mounting screw holes.

[0033] Among them, two fixing blocks 2 are respectively installed at the outer end of the chassis 102. A stabilizing rod 201 is fixedly installed between the two fixing blocks 2 by bolts. A slider 202 is installed on one side of the inner end of the stabilizing rod 201. Slide grooves a 203 for sliding connection with the slider 202 are opened on both sides of the outer end of the square tube 101. A sliding rod 204 is installed on the outer side of the chassis 102. A support plate 205 is arranged on the outer side of the chassis 102. A slide groove b 206 for sliding connection with the sliding rod 204 is opened on the inner side of the support plate 205.

[0034] When the driving chassis 102, the drilling motor 103 and the drill pipe 104 move up and down, stabilizing rods 201 are fixedly installed on both sides of the outer end of the chassis 102. The stabilizing rods 201 are slidably connected with the slide grooves a 203 on both sides of the outer end of the square tube 101 through the sliders 202 on the inner side. The sliding rod 204 on the outer side of the chassis 102 is slidably connected with the slide groove b 206 on the inner side of the support plate 205. During the use of the chassis 102, the drilling motor 103 and the drill pipe 104, stabilizing rods 201 and sliding rods 204 are added around the chassis 102 to stably support it. When the chassis 102, the drilling motor 103 and the drill pipe 104 move up and down, the stabilizing rods 201 on both sides of the outer end of the chassis 102 and the sliding rods 204 on the outer side will move up and down synchronously, ensuring good stability when the drill pipe 104 drills into the rock layer, avoiding the drill pipe 104 from shaking and affecting the stability of the entire equipment support 1, and ensuring the safe progress of exploration construction.

[0035] Among them, a fixing plate 6 is installed at the bottom of the outer end of the equipment support 1. A first U-shaped fixing block 601 is fixedly installed at the top of the fixing plate 6 by bolts. A second U-shaped fixing block 602 is fixedly installed at the outer end of the square tube 101 by bolts. A reinforcing rod 603 is fixedly installed between the second U-shaped fixing block 602 and the first U-shaped fixing block 601 by bolts.

[0036] When the square cylinder 101 is installed on the equipment support 1 for use, a reinforcing rod 603 is fixedly installed between the second U-shaped fixing block 602 and the first U-shaped fixing block 601 between the outer end of the square cylinder 101 and the fixing plate 6. The reinforcing rod 603 supports and places the outer end of the square cylinder 101, so that the force on the periphery of the square cylinder 101 is balanced, preventing the square cylinder 101 from tipping over during use.

[0037] Among them, a circular cylinder 4 is provided between the square cylinder 101 and the support plate 205. Activity holes 401 are opened on both sides of the outer end of the circular cylinder 4. A damper 402 is installed inside the activity holes 401. A spring 403 is installed between the damper 402 and the activity holes 401. An installation block b404 is installed at the outer end of the damper 402.

[0038] When one end of the chassis 102 is connected to the moving block 108 through the connecting rod 107 and the other end is slidably connected to the support plate 205 through the sliding rod 204, the dampers 402 on both sides of the outer end of the circular cylinder 4 can be respectively installed between the square cylinder 101 and the support plate 205. That is, the dampers 402 are respectively installed on the inner sides of the square cylinder 101 and the support plate 205 through the installation block b404 at the outer end, and the installation block b404 is tightened and fixed with bolts. When the drill rod 104 jitters when drilling into the rock layer and is transmitted to the square cylinder 101 and the support plate 205, the damper 402 compresses the spring 403 to make a buffering movement in the activity hole 401, which can reduce the jitter energy of the square cylinder 101 and the support plate 205, and improve the stability of the force on the chassis 102, the drilling motor 103 and the drill rod 104 during use.

[0039] Working principle:

[0040] When the equipment support 1 is placed in the exploration area for use, the equipment support 1 supports and places the square cylinder 101, the chassis 102, the drilling motor 103 and the drill pipe 104. At this time, hold the handwheel 503 with your hand and rotate the adjusting screw 502 clockwise. The adjusting screw 502 rotates with internal threads in the screw hole 501, so that the adjusting screw 502 moves towards the ground soil layer. Since the bottom end of the adjusting screw 502 is arranged in a sharp cone structure, when the bottom end of the adjusting screw 502 contacts the ground, continuously rotate the adjusting screw 502 and screw the adjusting screw 502 into the soil layer until the handwheel 503 fits the surface of the side wing plate 5, thereby stably placing the equipment support 1. Then start the stepping motor 105 and the drilling motor 103 to work. The drilling motor 103 drives the drill pipe 104 to rotate, and the stepping motor 105 drives the reciprocating lead screw 106 to rotate. Since the threaded hole inside the moving block 108 rotates with the threads of the reciprocating lead screw 106, and the connecting rod 107 passes through the moving groove 109 and is fixedly connected to the moving block 108. At this time, when the moving block 108 moves downward, it will drive the connecting rod 107, the chassis 102, the drilling motor 103 and the drill pipe 104 to move downward, so that the drill pipe 104 passes through the through hole 110 and moves towards the ground and drills into the soil layer. The stepping motor 105 and the drilling motor 103 respectively drive the reciprocating lead screw 106 and the drill pipe 104 to continuously work, so that the drill pipe 104 can drill into rock and soil layers of different depths. After the drill pipe 104 is removed from the soil surface, the rock and soil attached to the drill pipe 104 and the length of the soil imprint can be measured to complete the exploration work for bridge construction.

[0041] When driving the chassis 102, the drilling motor 103 and the drill pipe 104 to move up and down, stabilizing rods 201 are fixedly installed on both outer sides of the chassis 102. The stabilizing rods 201 are slidably connected to the sliding grooves a203 on both outer sides of the square cylinder 101 through the sliders 202 on the inner sides, and the sliding rods 204 on the outer side of the chassis 102 are slidably connected to the sliding grooves b206 on the inner side of the support plate 205. During the use of the chassis 102, the drilling motor 103 and the drill pipe 104, stabilizing rods 201 and sliding rods 204 are added around the chassis 102 to stably support it. When the chassis 102, the drilling motor 103 and the drill pipe 104 move up and down, the stabilizing rods 201 on both outer sides of the chassis 102 and the sliding rods 204 on the outer side will move up and down synchronously, ensuring good stability when the drill pipe 104 drills into the rock layer, avoiding the drill pipe 104 from shaking and affecting the stability of the entire equipment support 1, and ensuring the safe progress of exploration construction.
