[0032] See also Figure 1 and Figure 3 A retractable assembly 4 is installed on the top of the C-shaped plate, wherein the retractable assembly 4 includes a column 41, a first pulley 42, a support rod 43, a second pulley 44, a winding drum 45 and a winding motor 46; the column 41 is installed on the top wall of the C-shaped plate, the first pulley 42 is installed on the top of the column 41, the support rod 43 is installed on the left and right side walls of the column 41, the second pulley 44 is installed on the support rod 43, the winding motor 46 is arranged on the side wall of the column 41, the winding drum 45 is arranged on the output shaft of the winding motor 46, a connecting rope 5 (the connecting rope 5 is a steel wire rope) is wound on the winding drum 45, the connecting rope 5 is connected to the vibrating device 6 through the first pulley 42 and the second pulley 44, and the first pulley 42 and the second pulley 44 are used to guide the connecting rope 5.

[0033] It should be noted that the support rod 43 is a telescopic rod (such as an electric or hydraulic telescopic rod, etc.), which is used to adjust the distance between the second pulley 44 and the column 41 by extending and retracting the telescopic rod, so that the second pulley 44 can push the connecting rope 5 to move, thereby changing the distance between the vibrating equipment and the support plate 32, and adjusting the construction position of the vibrating equipment 6.

[0034] See also Figure 1 and Figure 3 A vibrating device 6 is provided on the end of the connecting rope 5 away from the winding drum 45. The vibrating device 6 includes a vibrating motor and a vibrating rod arranged on the output shaft of the vibrating motor. The end of the connecting rope 5 away from the winding drum 45 is detachably connected to the vibrating motor, so that the vibrating device 6 and the connecting rope 5 can be separated.

[0035] See also Figure 1 and Figure 4 A set 8 is provided on the hanging plate of the walking component 3, and the set 8 is sleeved on the outer wall of the connecting rope 5. There are several sets 8, and the several sets 8 are distributed in sequence from top to bottom.

[0036] A method for vibrating concrete of underground facilities, the method is as follows:

[0037] First, insert the plug of the bracket 2 into the foundation 1 of the construction area, and place the vibrating device 6 above the construction area;

[0038] It should be noted that the construction area in this application is taken as an example of a pool; a pit is excavated in the construction area, and a support assembly 7 is set in the pit (the support assembly 7 includes a template 71, a guide plate 72, and a scaffold 73, and the scaffold 73 is used to support the template 71 and the guide plate 72, such as Figure 1 and Figure 7 As shown), concrete is then poured into the template 71;

[0039] Second, after turning on the vibrating device 6, the winding motor 46 of the retractable assembly 4 is controlled to be energized to make the winding drum 45 rotate, release the connecting rope 5, move the vibrating device 6 downward to contact the concrete, and vibrate the concrete. After vibrating for a preset time (the preset time is a pre-set time, specifically twenty to thirty seconds), the winding motor 46 drives the winding drum 45 to rotate in the opposite direction, rewinds the connecting rope 5, and makes the vibrating device 6 rise and move out of the concrete. Then the traveling motor 34 of the traveling assembly 3 drives the track wheel 33 to rotate, so that the support plate 32 and the retractable assembly 4 move on the bracket 2, move with the vibrating device 6, change the vibration position, and repeat the above operation to make the vibrating device 6 vibrate other areas of the concrete until the concrete vibration construction is completed.

[0040] It should be noted that during the movement of the walking component 3, the kit 8 moves together with the walking component 3 to guide the connecting rope 5 and the vibrating device 6 (that is, the kit 8 will pull the connecting rope 5). Since the kit 8 guides the connecting rope 5, the connecting rope 5 will not separate from the first pulley 42 and the second pulley 44 during the movement; and since the kit 8 is closer to the vibrating device 6, the swing amplitude of the vibrating device 6 after movement is reduced, so that the vibrating device 6 can quickly perform the vibrating work, thereby improving the efficiency of concrete vibration, thereby improving the construction efficiency of underground facilities.

[0041] In this embodiment, as a further optimized solution, please refer to Figure 1 A supporting pulley 31 is provided on the hanging plate, and the supporting pulley 31 contacts the kick plate of the bracket 2; when the track wheel 33 rotates to make the support plate 32 walk on the railing of the bracket 2, the supporting pulley 31 also slides on the kick plate to assist the movement of the support plate 32.

[0042] Example 2

[0043] As a further optimized solution of Example 1, please refer to Figure 4 A mounting plate 9 is provided on the side wall of the hanging plate, and there are two sets 8, which are respectively arranged on the upper and lower sides of the mounting plate 9.

[0044] In this embodiment, as a further optimized solution, please refer to Figure 5 The lower side kit 8 includes a sleeve 81, a sponge layer 82 arranged on the inner wall of the sleeve 81, and a bristle layer 83 arranged on the inner wall of the sponge layer 82. A liquid reservoir 84 is arranged in the sleeve 81, and lubricating oil is filled in the liquid reservoir 84. An opening is arranged on the inner wall of the sleeve 81 (the opening is opened relatively small, and the opening is equivalent to a gap, so that the lubricating oil flowing out of the liquid reservoir 84 is slow and small in amount), and the opening is connected to the liquid reservoir 84. The sleeve 81 is installed on the mounting plate 9; the lubricating oil in the liquid reservoir 84 flows out from the opening and is absorbed by the sponge layer 82, and then flows onto the bristle layer 83. During the process of winding the connecting rope 5, the connecting rope 5 will pass through the bristle layer 83, and the lubricating oil will be brushed onto the outer wall of the connecting rope 5, which will have a lubricating effect and reduce the friction resistance between the movement of the connecting rope 5 and the lower side kit 8; and when the lower side kit 8 moves and pulls the connecting rope 5 together, the connecting rope 5 will be squeezed onto the sponge layer 82, which is used to squeeze out the lubricating oil in the sponge layer 82 and coat it on the outer wall of the connecting rope 5; the two ends of the lower sleeve 81 are trumpet-shaped, so that when the lower side kit 8 pulls the connecting rope 5 to move, the end wall of the lower side kit 8 will not contact the connecting rope 5, thereby reducing the wear of the connecting rope 5.

[0045] In this embodiment, as a further optimized solution, please refer to Figure 6The upper side kit 8 includes a sleeve 81, a mounting frame is provided in the sleeve 81, and two guide wheels 88 are symmetrically provided in the mounting frame. The two guide wheels 88 are located on both sides of the connecting rope 5 and are in contact with the connecting rope 5; the mounting plate 9 is slidably arranged on the side wall of the hanging plate (the mounting plate 9 can move up and down at the hanging plate), a rack 10 is provided on the side wall of the hanging plate, and a traveling gear 11 is rotatably provided on the mounting plate 9. The traveling gear 11 is meshed with the rack 10, and the traveling gear 11 and the guide wheel 88 are transmitted through a transmission assembly 89 (the transmission assembly 89 includes two transmission wheels and a conveyor belt, and the two transmission wheels are respectively fixedly sleeved on the shaft of the traveling gear 11 and the outer wall of the shaft of a guide wheel 88, and the two transmission wheels Through the conveyor belt transmission); when the retractable component 4 carries the winding rope 5 to move the vibrating device 6 upward, the upward movement of the rope 5 will cause the guide wheel 88 to rotate, and through the transmission component 89, the travel gear 11 rotates and travels on the rack 10, which is used to drive the mounting plate 9 and the two kits 8 to move upward; when the retractable component 4 releases the rope 5 to move the vibrating device 6 downward, the guide wheel 88 rotates in the opposite direction, causing the travel gear 11 to rotate in the opposite direction to drive the mounting plate 9 and the two kits 8 downward, so that the mounting plate 9, the kit 8 and the vibrating device 6 are lifted and lowered synchronously, reducing the distance between the lower kit 8 and the vibrating device 6, and further reducing the probability of shaking of the vibrating device 6 after moving.

[0046] In this embodiment, as a further optimized solution, please refer to Figure 5 A movable block 86 is provided on the side wall of the sleeve 81, and a mounting block 85 is slidably sleeved on the outer wall of the movable block 86. An elastic member 87 (spring) is provided between the mounting block 85 and the movable block 86, and the mounting block 85 is connected to the mounting plate 9; the movable block 86 is moved on the outer wall of the mounting block 85 by the expansion and contraction of the elastic member 87, so that the distance between the kit 8 and the hanging plate can be adaptively adjusted to meet different usage requirements, reduce the pressure caused by the kit 8 on the connecting rope 5, and extend the service life of the connecting rope 5.
