Description

Technical Field

[0001] The utility model belongs to the field of municipal rail transit construction equipment, in particular to a wall brush for underground continuous wall construction. Background Art

[0002] An underground continuous wall is a continuous reinforced concrete wall built underground that has the functions of water interception, anti-seepage, load bearing and water retaining. During construction, workers need to use trenching equipment to dig a narrow and long deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection, and after cleaning the trench, hang a steel cage inside the trench, and then use the conduit method to pour underwater concrete to form a unit trench section, and then proceed section by section to form an underground continuous wall.

[0003] After the construction of the first section of the underground continuous wall is completed, in order to facilitate the connection with the subsequent unit sections, the staff needs to brush the edge steel of the first section to clean up the bypass and remove the soil that the grooving machine has not caught inside the H-steel, so as to avoid leakage of the wall at the connection.

[0004] Existing wall brushes are usually welded with steel plates of the same width as the channel steel to form a box body, and brush heads matching the wall surface are made on both sides or one side of the box body. When in use, the wall brush needs to be lifted obliquely by a crane to clean the underground continuous wall. However, since the crane's lever arm is long and the posture of the wall brush cannot be fixed after lifting, it is very easy to cause the wall brush to tilt, thereby affecting the wall brushing effect. To solve this problem, technicians in this field will choose to increase the deadweight of the wall brush so that the wall brush is close to the steel after lifting, but increasing the deadweight of the wall brush will reduce the flexibility of the wall brush, which will seriously affect the wall cleaning efficiency.

[0035] In the actual working process, there are differences in the operable space near different continuous walls, and the engineering equipment used by each construction unit also has different size specifications. Therefore, when performing the wall brushing operation, the staff needs to adjust the posture of the wall brush according to the actual situation to ensure that the wall brushing work can be carried out smoothly. To achieve this purpose, the scraper 2 in this embodiment is arranged with an adjustable angle inside the installation channel, and the adjustment component for adjusting the angle of the scraper 2 is arranged below the scraper 2, and one end of the adjustment component is hinged to the bottom surface of the scraper 2, and the other end is hinged to the connecting seat 1. When the angle of the scraper 2 needs to be adjusted, the staff can drive the adjustment component to extend or shorten so that the scraper 2 can be flipped upward and then downward inside the installation channel.

[0036] Optional, such as Figure 4 As shown, the adjustment assembly may include: a first adjustment screw 71, a second adjustment screw 72 and an adjustment member, wherein the top end of the first adjustment screw 71 is hinged to the scraper 2, and the bottom end of the second adjustment screw 72 is hinged to the connecting seat 1. The adjustment member may include a first adjustment ring 731 and a second adjustment ring 732, wherein the inner side wall of the first adjustment ring 731 is provided with an internal thread matched with the first adjustment screw 71, the inner side wall of the second adjustment ring 732 is provided with an internal thread matched with the second adjustment screw 72, and the second adjustment ring 732 is connected to the first adjustment ring 731 through an adjustment connecting rod 733.

[0041] Since the mounting plate 3 is connected to the scraper 2 through the connecting rod 5, and the two ends of the connecting rod 5 are respectively hinged to the mounting plate 3 and the scraper 2, when the scraper 2 is adjusted in posture under the action of the adjustment component, the mounting plate 3 can drive the first brush head 4 to move synchronously, thereby reducing the difficulty of adjusting the angle of the brush head assembly.

[0042] In order to realize the detachable connection between the first brush head 4 and the mounting plate 3, a first connecting hole is provided on the first brush head 4, and a connecting bolt 41 is provided inside the first connecting hole. Correspondingly, a second connecting hole 31 should be provided on the mounting plate 3. During assembly, the staff can insert the connecting bolt 41 into the second connecting hole 31 and limit the connecting bolt 41 with the help of a nut, so that the first brush head 4 is reliably fixed on the mounting plate 3.

[0043] Optionally, in order to improve the cleaning ability of the brush head assembly, the brush head assembly in this embodiment may further include a second brush head 8. Figure 5 As shown, the second brush head 8 is detachably arranged above the first brush head 4, and a wire bristle 6 is provided on the side wall of the second brush head 8 away from the connecting seat 1. In order to realize the connection between the second brush head 6 and the first brush head 4, a plurality of mounting posts 42 are provided on the top surface of the first brush head 4, each mounting post 42 should be provided with a threaded post, and a limiting nut 44 is provided on the threaded post. Correspondingly, a plurality of mounting holes 81 should be provided on the second brush head 8. During assembly, the staff can first remove the limiting nut 44, then insert the mounting post 42 into the mounting hole 81, and then sleeve the limiting nut 44 onto the threaded post, so as to prevent the second brush head 8 from being separated from the mounting post 42 with the help of the limiting nut 44.

[0044] In addition, in order to prevent the second brush head 8 from damaging the outer surface of the continuous wall during the wall brushing process, a spring 43 may be sleeved on the mounting column 42, and one end of the spring 43 should be connected to the first brush head 4, and the other end should be connected to the second brush head 8. The spring 43 can be provided to enable the second brush head 8 to obtain elastic floating ability, so that when the second brush head 8 is subjected to excessive stress, it moves toward the first brush head 4 due to the elastic deformation of the spring 43, thereby preventing the second brush head 8 from damaging the continuous wall.

[0045] As another optional implementation of this embodiment, in order to improve the cleaning effect of the device on external attachments of the continuous wall, a cleaning blade 21 can be provided on the side wall of the scraper 2 away from the connecting seat 1, so as to reduce the difficulty of separating the attachments from the continuous wall with the help of the cleaning blade 21.
