Abstract
Description
Technical Field
[0001] The invention relates to the technical field of underground continuous wall construction, in particular to a wall cleaning tool for H-shaped steel joints of a reinforcement cage of an underground continuous wall. Background Art
[0002] After the trenching machine has finished digging the trench section of the underground continuous wall using the H-shaped steel joint, a steel cage needs to be placed in the trench. After the steel cage is placed, the H-shaped steel joint of the steel cage needs to be brushed to remove the silt in the H-shaped steel joint to ensure the compaction of the subsequent underwater concrete and H-shaped steel. Most of the brushing tools currently used connect the tool to the bucket of the trenching machine through a pin, and then the trenching machine drives the bucket to rise and fall back and forth in the trench for multiple times, so that the bristles of the brushing tool on the bucket brush the H-shaped steel joint of the steel cage. Since the bucket is fan-shaped, after the wall brushing tool is fixedly connected to the bucket by a pin, it is necessary to open and close the grab bucket to press the bristles of the wall brushing tool against the H-steel joint. However, the opening and closing size of the grab bucket is controlled by the operator. When the grab bucket is opened at a large angle, although the bristles of the wall brushing tool can be pressed against the H-steel joint, the large opening angle of the grab bucket will exert greater pressure on the wall brushing tool, which may easily cause damage to the wall brushing tool; when the grab bucket is opened at a small angle, it is difficult for the bristles of the wall brushing tool to be pressed against the H-steel joint, which makes it difficult to brush off some lumps solidified at the H-steel joint; at the same time, since the bucket is fan-shaped, it is difficult for the operator to ensure that the wall brushing tool remains parallel to the H-steel joint during the opening of the bucket, which may easily lead to a small contact area between the bristles of the wall brushing tool and the H-steel joint during the wall brushing process, making it difficult to clean the silt adhering to the wall of the H-steel joint. Summary of the invention
[0003] The invention provides a wall cleaning tool for H-shaped steel joints of a steel cage of an underground continuous wall, which can overcome certain defects of the prior art.
[0004] According to the present invention, a wall cleaning tool for H-shaped steel joints of a steel cage of an underground continuous wall comprises: a tool body, the tool body comprises a first mounting seat connected to a grab bucket, and a second mounting seat matched with the H-shaped steel joint; a first mounting plate is provided below the second mounting seat along the length direction of the second mounting seat; a wire brush is provided at one end of the first mounting plate away from the second mounting seat; a mounting hole is provided at the lower end of the second mounting seat along the width direction of the second mounting seat, a pushing mechanism for pushing the first mounting plate close to the H-shaped steel joint is provided in the mounting hole; a trigger mechanism is provided below the first mounting seat, the trigger mechanism is used to cooperate with the pushing mechanism, and when the first mounting seat extends into the bottom of the groove, the pushing mechanism pushes the first mounting plate to extend toward the H-shaped steel joint.
[0005] By means of the present invention, during the construction of the ground-connected wall, after the ground-connected wall is grooved by the groove forming machine, a steel cage is placed in the groove. After the steel cage is placed, the construction personnel pass a pin through the reinforcing plate on the first mounting seat on the bucket of the original groove forming machine, thereby connecting and fixing the tool body with the bucket. After the connection is completed, the grab bucket is placed into the groove by the groove forming machine. When the grab bucket reaches the bottom of the groove, the telescopic rod on the tool body will first contact the bottom of the groove. As the grab bucket continues to move downward, the telescopic rod will rise. At this time, the inclined surface on the telescopic rod will squeeze the mounting rod, causing the mounting rod to move, thereby pushing the first mounting plate to move toward the H-shaped steel joint until the wire brush is pressed against the H-shaped steel joint. This prevents the wire brush from being insufficiently in contact with the H-shaped steel joint, resulting in poor efficiency when cleaning the H-shaped steel joint. When the wire brush squeezes the H-shaped steel joint, the wire brush is deformed, and the wire brush provides a reaction force, so that the first mounting plate is squeezed and pushed, thereby pushing the first sliding rod and the sliding block to slide along the mounting cavity. During the movement of the sliding block, the second sliding rod is pushed out of the fourth through hole and into the limiting groove. When the second sliding rod is inserted into the limiting groove, the telescopic rod is blocked from continuing to move up and down, thereby pressing the wire brush against the H-shaped steel joint. At this time, the construction personnel lift the grab bucket by controlling the slotting machine, and the wire brush is always pressed against the H-shaped steel joint to prevent the wire brush from loosening, resulting in poor efficiency in cleaning the H-shaped steel joint. After the grab bucket rises and leaves the groove, the tool body leaves the groove at the same time. After the wire brush is separated from the H-shaped steel joint, the fourth spring will push the sliding block to move, so that the sliding block drives the second sliding rod to retract into the fourth through hole, so that the second sliding rod is separated from the limiting groove. After the second sliding rod is separated from the limiting groove, the second spring in the second mounting groove will push the telescopic rod to move downward. After the telescopic rod moves downward, the first spring will push the third mounting plate to move. The movement of the third mounting plate drives the mounting rod to move, so that the arc surface on the mounting rod is against the inclined surface on the telescopic rod again, so that the mounting rod is retracted, so that the wire brush and the first mounting plate return to the initial position, and the reset is completed; The tool body is used so that when the grab bucket drives the tool body downward into the groove, the wire brush does not contact the H-beam joint, thereby preventing the concrete blocks, stones or soil on the H-beam joint from being scraped into the groove when the tool body moves downward, which requires the construction workers to clean the groove again. Through the cooperation of the pushing mechanism and the trigger mechanism, when cleaning the H-beam joint, the construction personnel do not need to adjust the opening and closing size of the grab bucket to control the pressure of the wire brush against the H-beam joint, thus avoiding the need for the construction personnel to adjust the opening and closing size of the grab bucket to control the pressure of the wire brush against the H-beam joint every time the wall is brushed; Compared with the prior art, the tool body does not rely on a grab bucket and can also be used in conjunction with other lifting devices to perform digging and wall brushing construction.

[0036] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.
[0037] Example 1 like Figure 1-11 As shown, the present embodiment provides a wall cleaning tool for H-shaped steel joints of a steel cage of an underground continuous wall, comprising a tool body 100, the tool body 100 comprising a first mounting seat 140 connected to a grab bucket, and a second mounting seat 120 cooperating with the H-shaped steel joint; a first mounting plate 360 is provided below the second mounting seat 120 along the length direction of the second mounting seat 120; a wire brush 130 is provided at one end of the first mounting plate 360 away from the second mounting seat 120; a mounting hole 470 is provided at the lower end of the second mounting seat 120 along the width direction of the second mounting seat 120, and a pushing mechanism for pushing the first mounting plate 360 close to the H-shaped steel joint is provided in the mounting hole 470; a trigger mechanism is provided below the first mounting seat 140, the trigger mechanism is used to cooperate with the pushing mechanism, and when the first mounting seat 140 extends into the bottom of the groove, the pushing mechanism pushes the first mounting plate 360 to extend toward the H-shaped steel joint.
[0038] Through this embodiment, during the construction of the ground-connected wall, after the ground-connected wall is grooved by the groove forming machine, a steel cage is placed in the groove. After the steel cage is placed, the construction personnel pass the reinforcing plate 620 on the first mounting seat 140 through the pin on the bucket of the original groove forming machine, so as to connect and fix the tool body 100 with the bucket; after the connection is completed, the grab bucket is placed into the groove by the groove forming machine. When the grab bucket reaches the bottom of the groove, the telescopic rod 230 on the tool body 100 will first contact the bottom of the groove. As the grab bucket continues to move downward, the telescopic rod 230 will rise. At this time, the inclined surface 830 on the telescopic rod 230 will squeeze the mounting rod 260, so that the mounting rod 260 moves, thereby pushing the first mounting plate 360 to move toward the H-shaped steel joint until the wire brush 130 is pressed against the H-shaped steel joint; thereby preventing the wire brush 130 from insufficiently contacting the H-shaped steel joint, resulting in poor efficiency when cleaning the H-shaped steel joint; When the wire brush 130 squeezes the H-shaped steel joint, the wire brush 130 is deformed, and the wire brush 130 provides a reaction force, so that the first mounting plate 360 is squeezed and pushed, thereby pushing the first sliding rod 206 and the sliding block 203 to slide along the mounting cavity 201. During the movement of the sliding block 203, the second sliding rod 290 is pushed to extend out of the fourth through hole 280 and extend into the limiting groove 820. When the second sliding rod 290 extends into the limiting groove 820, the telescopic rod 230 is blocked from continuing to move up and down, thereby pressing the wire brush 130 against the H-shaped steel joint. At this time, the construction personnel lift the grab bucket by controlling the grooving machine, and the wire brush 130 is always kept pressed against the H-shaped steel joint to prevent the wire brush 130 from loosening, resulting in poor efficiency when cleaning the H-shaped steel joint. After the grab bucket rises and leaves the groove, the tool body 100 leaves the groove at the same time. After the wire brush 130 is separated from the H-shaped steel joint, the fourth spring 202 will push the sliding block 203 to move, so that the sliding block 203 drives the second sliding rod 290 to retract into the fourth through hole 280, so that the second sliding rod 290 is separated from the limiting groove 820. After the second sliding rod 290 is separated from the limiting groove 820, the second spring 320 in the second mounting groove 210 will push the telescopic rod 230 to move downward. After the telescopic rod 230 moves downward, the first spring 350 will push the third mounting plate 340 to move. The movement of the third mounting plate 340 drives the mounting rod 260 to move, so that the arc surface 710 on the mounting rod 260 is against the inclined surface 830 on the telescopic rod 230 again, so that the mounting rod 260 is retracted, so that the wire brush 130 and the first mounting plate 360 return to the initial position, and the reset is completed. The tool body 100 prevents the wire brush 130 from contacting the H-shaped steel joint when the grab bucket drives the tool body 100 downward into the groove, thereby preventing the concrete blocks, stones or soil on the H-shaped steel joint from being scraped into the groove when the tool body 100 moves downward, thereby requiring the construction personnel to clean the groove again. Through the cooperation of the pushing mechanism and the trigger mechanism, when cleaning the H-shaped steel joint, the construction personnel do not need to adjust the opening and closing size of the grab bucket to control the pressure of the wire brush 130 against the H-shaped steel joint, thus avoiding the need for the construction personnel to adjust the opening and closing size of the grab bucket to control the pressure of the wire brush 130 against the H-shaped steel joint every time the wall is brushed; Compared with the prior art, the tool body 100 does not rely on a grab bucket, and can also cooperate with other lifting devices to perform digging and wall brushing construction.

After the wire brush 130 is separated from the H-shaped steel joint, the fourth spring 202 will push the sliding block 203 to move, so that the sliding block 203 drives the second sliding rod 290 to retract into the fourth through hole 280, so that the second sliding rod 290 is separated from the limiting groove 820. After the second sliding rod 290 is separated from the limiting groove 820, the second spring 320 in the second mounting groove 210 will push the telescopic rod 230 to move downward. After the telescopic rod 230 moves downward, the first spring 350 will push the third mounting plate 340 to move. The movement of the third mounting plate 340 drives The mounting rod 260 moves, so that the arc surface 710 on the mounting rod 260 is again against the inclined surface 830 on the telescopic rod 230, so that the mounting rod 260 is retracted, so that the wire brush 130 and the first mounting plate 360 return to the initial position and complete the reset; thereby, the wire brush 130 can automatically complete the reset, so that when the tool body 100 is extended into the groove, the wire brush 130 does not contact the H-shaped steel joint; when rising in the groove, the wire brush 130 contacts the H-shaped steel joint; and blocks such as concrete blocks, stones or soil on the H-shaped steel joint are prevented from being scraped into the groove when the tool body 100 moves downward, thereby requiring construction personnel to clean the groove again.
