Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a curbstone joint filling device. Background Art

[0002] The curbstones are prefabricated. After they are arranged on the roadside, the gaps between the curbstones are filled. In the process of construction technology development, some tools and equipment such as curbstone feeding tools, curbstone caulkers, and curbstone gap filling devices have appeared. The tools are clamped on both sides of the curbstone gap through a rigid profiling structure to seal both sides of the curbstone gap, and grouting is carried out into the gap through the reserved grouting port.

[0003] The existing curbstone caulking device still needs to manually find the stone joints during construction and then fill the gaps. The process of filling the stone joints one by one is cumbersome and inconvenient to operate. In addition, since the gaps between the stone joints are generally small, the mortar is easily scattered outside when pouring, which is difficult to clean.

[0004] Therefore, we propose a curbstone caulking device to solve the above-mentioned problems. Utility Model Content

[0005] The utility model provides a curbstone caulking device, which solves the problem that the existing curbstone caulking device mentioned in the above background technology still needs to manually find the stone joints during construction and then fill the gaps.

[0011] As an optional solution described in the utility model, wherein: the side wall of the slot is slidably connected with a slider, and a plurality of springs are fixedly installed between the inner wall of the slider and the inner wall of the slot.

[0012] The utility model has the following beneficial effects:

[0013] 1. When it is necessary to fill the gaps between the curbstones, the external shell can be placed on the surface of the curbstone so that it is close to the curbstone, and then the external shell can be pushed along the surface of the curbstone. At this time, under the pressure of the upper wall of the curbstone, the lower end of the movable block is flush with the upper end surface of the curbstone, and the opening at the lower end of the movable block is blocked under the action of the fixed plate. When the external shell slides to the point where the movable block is directly opposite to the gap between the curbstones, the movable block is automatically pushed downward and stuck in the gap under the action of spring 1.

[0024] When it is necessary to fill the gap between the curbstones 2, the outer shell 1 can be placed on the surface of the curbstone 2 first to make it close to the curbstone 2, and then the outer shell 1 can be pushed along the surface of the curbstone 2. At this time, under the pressure of the upper wall of the curbstone 2, the lower end of the movable block 13 is flush with the upper end surface of the curbstone 2, and the opening 131 at the lower end of the movable block 13 is blocked under the action of the fixed plate 15. When the outer shell 1 slides until the movable block 13 is opposite to the gap between the curbstone 2, the movable block 13 is automatically pushed down and stuck in the gap under the action of the spring 14. At this time, the mortar in the empty groove 11 automatically flows down along the opening 131 into the gap to fill the gap. After a period of time, the outer shell 1 can be pushed again to fill the next gap. The device can be pushed along the surface of the curbstone 2. When the device moves to the gap to be filled, mortar can automatically flow into the gap, close to the surface of the curbstone, and the operation is relatively convenient.

[0025] Example 2

[0026] See also Figure 2 - Figure 5 A shell 3 is fixedly installed on the side wall of the external shell 1, a motor 31 is fixedly installed in the shell 3, and shafts 32 are rotatably connected to both sides of the inner wall of the slot 11. The output end of the motor 31 is fixedly connected to one of the shafts 32. With the cooperation between the external shell 1, the shell 3, the motor 31, the slot 11 and the shaft 32, the motor 31 can start to drive the shaft 32 to rotate.

[0027] A transmission belt 33 is sleeved between the two rotating shafts 32, and a roller brush 34 is fixedly installed on the outer sides of the two rotating shafts 32. With the cooperation between the rotating shafts 32, the transmission belt 33 and the roller brush 34, the rotation of the rotating shaft 32 can drive the other rotating shaft 32 to rotate together.

[0028] A stone gap 21 is left between the two curbstones 2, a groove 16 is opened on the external shell 1, and a clamping strip 4 is slidably connected to the side wall of the groove 16. The clamping strip 4 can be slidably connected in the stone gap 21. With the cooperation between the curbstone 2, the stone gap 21, the external shell 1, the groove 16 and the clamping strip 4, the side of the curbstone 2 can be blocked by the clamping strip 4.

[0029] A push block 17 is slidably connected inside the outer shell 1, one side of the push block 17 is opposite to the stone gap 21, and the side wall of the push block 17 is in contact with the side wall of the clamping strip 4. With the cooperation between the outer shell 1, the push block 17, the stone gap 21 and the clamping strip 4, the push block 17 can push the clamping strip 4 to be clamped in the stone gap 21.

[0030] The side wall of the slot 16 is slidably connected with a slider 18, and a plurality of springs 19 are fixedly installed between the inner wall of the slider 18 and the inner wall of the slot 16. With the cooperation between the slot 16, the slider 18 and the springs 19, the slider 18 can automatically push the card strip placed in the slot 16 to the side wall of the slot 16.

[0031] When filling the stone gap 21 of the curb 2, the motor 31 can be started first. The motor 31 runs in the housing 3. The output end of the motor 31 drives one of the rotating shafts 32 to rotate together. The stone rotated by the rotating shaft 32 drives the other rotating shaft 32 to rotate in the empty groove 11 through the transmission belt 33. When the two rotating shafts 32 rotate, they drive the roller brush 34 to run together in the empty groove 11, stirring the mortar in the empty groove 11 to prevent the mortar from condensing, and also to help the flow of the mortar when the mortar flows out. A part of the seal 4 can be placed in the slot 16 first, and the multiple seals 44 are arranged in order under the cooperation between the slider 18 and the multiple springs 19. The push block 17 is arranged in the slot 16. When the opening 131 discharges mortar downward for filling the gap, the push block 17 can be pulled outward, and the seal 4 is automatically pushed to be close to the slot 16 under the action of the spring 19. At this time, the push block 17 can be pushed inward. The push block 17 is pushed inward to drive one of the seals 4 to slide to the stone gap 21, and then continue to push inward for a short distance to vertically block the outer opening of the stone gap 21. At this time, the mortar flowing into the stone gap 2 will not flow out. The device can drive the roller brush 34 to rotate continuously under the action of the motor 31, which can prevent the mortar from condensing and facilitate the flow of the mortar. Under the action of the seal 4, the mortar can be prevented from flowing out.
