Description

Technical Field

[0001] This utility model relates to the technical field of underground wall construction, specifically to a wall brushing device for the side wall of an I-beam of an underground continuous wall. Background Technology

[0002] When excavating trenches for diaphragm walls, to ensure the smooth lowering of the reinforcing cage with I-beam joints into the construction trench section, the grab bucket extends the trench section outwards by approximately 70cm at both ends during excavation, creating a pouring section and an empty section. Before pouring the wall concrete, sandbags are filled at the over-excavated I-beam joints on both sides, i.e., the empty section, to prevent seepage during concrete pouring in the pouring section. However, in actual construction, concrete inevitably seeps into the empty section and adheres to the I-beam joints. Therefore, during the construction of the empty section, the I-beam joints need to be pre-treated with a brushing process.

[0003] The wall brush cannot move on its own using the punching machine. It needs to be lifted and transported on-site by a crane to change its position. The whole process is time-consuming and labor-intensive. The square punch is heavy and is prone to displacement during the wall brushing process, making it difficult to control and resulting in poor brushing effect. At the same time, when removing concrete blocks and sandbags, the punch and brush head need to be changed constantly, which delays the construction progress. Summary of the Invention

[0004] The purpose of this invention is to provide a wall brush for the side wall of an underground continuous wall I-beam, so as to solve the above-mentioned defects caused by the prior art.

[0005] A wall-cleaning device for the sidewall of an I-beam in a diaphragm wall includes a rotary drilling shaft with a flange welded to its outer side. A housing is connected to the top of the flange. A cleaning mechanism is provided on one side of the housing. This cleaning mechanism adjusts the cleaning size and material according to cleaning requirements, facilitating effective cleaning of different deposits on the surface of the I-beam. A drive mechanism is provided on one side of the cleaning mechanism, adjusting its range of motion according to the size of the I-beam and cleaning needs, thereby improving the efficiency of I-beam cleaning.

[0006] Preferably, the cleaning mechanism includes a telescopic dustproof mat, a cleaning arm, a concrete block brush head, and a wire brush. One side of the telescopic dustproof mat is connected to the outside of the equipment housing, and the other side of the telescopic dustproof mat is connected to the cleaning arm. The cleaning arms are symmetrically arranged on both sides of the equipment housing. A wire brush is connected to the outside of one set of cleaning arms, and a concrete block brush head is connected to the outside of the other set of cleaning arms.

[0007] Preferably, the concrete block brush head is connected to the displacement block via a cleaning arm provided on one side.

[0008] Preferably, the driving mechanism includes an electric cylinder, a displacement block, fastening holes, a guide rod, fasteners, and a spring column. The electric cylinder is installed inside the equipment housing. The output end of the electric cylinder is connected to the displacement block. Fastening holes are symmetrically opened on the outer side of the displacement block. Fasteners are connected inside the fastening holes. A cleaning arm is connected through the fasteners. The outer side of the guide rod is connected through the displacement block. The other end of the guide rod is connected to a spring column.

[0009] Preferably, the displacement block is connected to the outside of the cleaning arm by symmetrical through-connecting fasteners.

[0010] Preferably, the device housing is connected to the top of the displacement block via an internally installed electric cylinder.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The materials required for this application are inexpensive and readily available. The structure is simple, portable, and efficient. The dimensions can be modified and replaced according to the different diameters of the underground continuous wall, with high adaptability and good wall brushing effect. During use, the electric cylinder drives the concrete block brush head and wire brush to repeatedly brush, thereby improving the efficiency of cement tilting on the surface of the I-beam and avoiding the situation where some material remains on the surface of the I-beam during the one-way cleaning process.

[0013] 2. During use, the electric cylinder moves the displacement block up and down, and the displacement block moves the two sets of cleaning arms on one side up and down frequently, thereby controlling the cleaning force and range and improving the efficiency of the I-beam in the cleaning process.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 4 As shown, a wall-cleaning device for the sidewall of an I-beam in a continuous underground wall includes a rotary drilling shaft 1. A flange 3 is welded to the outer side of the rotary drilling shaft 1. A housing 2 is connected to the top of the flange 3. A cleaning mechanism 7 is provided on one side of the housing 2. The cleaning mechanism 7 can move the cleaning size and material according to the cleaning requirements, thereby facilitating the effective cleaning of different attachments on the surface of the I-beam. A driving mechanism 9 is provided on one side of the cleaning mechanism 7. The driving mechanism 9 can adjust the range of motion of the cleaning mechanism 7 according to the size of the I-beam and the cleaning requirements, thereby improving the efficiency of cleaning the I-beam.

[0022] In this embodiment, the cleaning mechanism 7 includes a telescopic dustproof mat 4, a cleaning arm 5, a concrete block brush head 6, and a wire brush 8. One side of the telescopic dustproof mat 4 is connected to the outside of the equipment housing 2, and the other side of the telescopic dustproof mat 4 is connected to the cleaning arm 5. The cleaning arms 5 are symmetrically arranged on both sides of the equipment housing 2. The outer side of one set of cleaning arms 5 is connected to the wire brush 8, and the outer side of the other set of cleaning arms 5 is connected to the concrete block brush head 6.

[0023] In this embodiment, the concrete block brush head 6 is connected to the displacement block 11 through a cleaning arm 5 provided on one side. The cleaning arm 5 drives the concrete brush head 6 to move repeatedly, thereby completing the repeated cleaning of the channel steel.

[0024] In this embodiment, the driving mechanism 9 includes an electric cylinder 10, a displacement block 11, a fastening hole 12, a guide rod 13, a fastener 14, and a spring column 15. The electric cylinder 10 is installed inside the equipment housing 2. The output end of the electric cylinder 10 is connected to the displacement block 11. The outer side of the displacement block 11 is symmetrically provided with fastening holes 12. The fastener 14 is connected inside the fastening hole 12. The cleaning arm 5 is connected through the fastener 14. The outer side of the guide rod 13 is connected through the displacement block 11. The other end of the guide rod 13 is connected to the spring column 15.

[0025] In this embodiment, the displacement block 11 is connected to the outside of the cleaning arm 5 by a fastener 14 that is symmetrically connected through it, and the fastener 14 that is installed through the displacement block 11 is connected to the cleaning arm 5.

[0026] In this embodiment, the device housing 2 is connected to the top of the displacement block 11 via an internally installed electric cylinder 10. The electric cylinder 10 drives the displacement block 11 to move repeatedly, thereby improving the cleaning efficiency.

[0027] In practical applications, this type of underground continuous wall I-beam sidewall brushing device includes the following tasks:

[0028] Step 1: The operator first selects the appropriate size concrete block brush head 6 and wire brush 8 according to the usage requirements, installs the concrete block brush head 6 and wire brush 8 on the outside of the cleaning arm 5, aligns the outside of the cleaning arm 5 with the fastening hole 12, inserts the fastener 14 into the connection between the concrete block brush head 6 and wire brush 8 and the cleaning arm 5, thereby completing the connection between the cleaning arm 5 and the concrete block brush head 6, so that the concrete block brush head 6 and wire brush 8 can be connected to the channel steel.

[0029] Step 2: After the second-phase trench is properly positioned, the underground continuous wall trenching machine is removed and replaced with a rotary drilling rig carrying the wall brushing device of this application. Since the rotary drilling rig uses tracks, it can move on its own and is positioned quickly. At the same time, the operator attaches the telescopic dustproof mat 4 to the outside of the equipment shell 2, and connects one end of the telescopic dustproof mat 4 to the outside of two sets of cleaning arms 5. Then, the cleaning arms 5 are used to pull and extend one side of the telescopic dustproof mat 4 to reduce the amount of mud and sand entering the interior of the equipment shell 2.

[0030] Step 3: The operator connects the output end of the electric cylinder 10 to the top of the displacement block 11. The electric cylinder 10 drives the displacement block 11 and the cleaning arm 5 to perform frequent displacement processing. First, the concrete block brush head 6 set on one side of the equipment housing 2 is used to clean the side wall of the I-beam from the top, as close to the side wall of the I-beam as possible, to the bottom. Because the adhesion between the concrete block and the I-beam is not good, the spring column 15 reduces the lifting force of the cleaning arm 5 to prevent the displacement block 11 from getting stuck.

[0031] Step 4: When the rotary drilling rig drives the rotary shaft 1, the mechanical force is relatively large. Most of the concrete blocks will be peeled off by the I-beam and fall to the bottom of the diaphragm wall during this process, achieving the cleaning effect of removing hard objects such as concrete blocks from the side wall of the I-beam. Then, use the wire brush 8 on the equipment housing 2 to remove the woven bags and small pieces of hard objects from the side of the I-beam, thereby completing the cleaning of the side wall of the I-beam.

[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
