DETAILED DESCRIPTION

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, an asphalt pavement bulging repair device includes a liquid storage tank 1 and a supply pipe 2, and a leveling plate 5 for leveling asphalt curing agent.

[0024] The ball shaft 6, which is used to form a universal rotational fit between the supply tube 2 and the flat plate 5, includes an upper hemispherical bladder 7 and a lower hemispherical bladder 8, and a protrusion 10 is provided between the upper hemispherical bladder 7 and the lower hemispherical bladder 8 to maintain a predetermined distance.

[0025] The ball shaft 6 is slidably disposed at the end of the supply pipe 2, and a block 21 is fixedly disposed inside the supply pipe 2 to block the liquid inlet of the ball shaft 6 at a predetermined height.

[0026] Specifically, the leveling plate 5 has a ball seat 51 for rotating the ball shaft 6. In the default state, the upper hemisphere 7 and the lower hemisphere 8 are kept at a predetermined distance by the elastic support of the protrusion 10. At this time, the plug 21 is close to the port of the ball shaft 6, so that the liquid inlet of the ball shaft 6 is sealed by the plug 21. Then, the leveling plate 5 is placed against the crack in the road surface to be repaired. At this time, the angle between the leveling plate 5 and the ball shaft 6 can be adjusted. The ball shaft 6 is manually stretched, so that the distance between the plug 21 and the port of the ball shaft 6 increases. The asphalt curing agent enters the ball shaft 6 through the supply pipe 2, and then enters the crack through the opening on the ball shaft 6. The injection tube 9 is fixedly installed on the upper hemisphere 7 and slidably inserted into the lower hemisphere 8. While stretching the ball shaft 6, it causes the distance between the upper hemisphere 7 and the lower hemisphere 8 to shorten. At this time, the protrusion 10 is subjected to pressure from the upper and lower sides and bulges outward and abuts against the inner wall of the ball seat 51. The friction of the protrusion 10 against the inner wall of the ball seat 51 plays a damping role, so that the angle between the ball shaft 6 and the flat plate 5 is fixed.

[0027] Furthermore, a handle 3 is fixedly installed on the supply pipe 2. After the angle between the flat plate 5 and the ball shaft 6 is fixed, the operator only needs to hold the handle 3 and move the supply pipe 2 horizontally to simultaneously replenish the curing agent and smooth the surface. Moreover, since the angle of the flat plate 5 is restricted, the operation of re-leveling the angle can be reduced.

[0028] In the above technology, the leveling plate 5 allows for the simultaneous replenishment of curing agent and smoothing. The angle of the leveling plate 5 can be adjusted in real time according to the site conditions. Only when the angle is convenient for operation will the ball shaft 6 be pulled to ensure unobstructed flow of the liquid inlet. This ensures that the asphalt curing agent can only be used after the leveling plate 5 is in place. Since the angle of the leveling plate 5 is restricted, the operation of re-leveling the angle can be reduced.

[0029] As a further provided embodiment of the utility model, the number of the flat plates 5 is two and they are arranged to rotate relative to each other, and the ball shaft 6 is provided with an injection pipe 9 penetrating the flat plates 5.

[0030] Specifically, a hinge 52 is arranged between the flat plates 5 to enable the two flat plates 5 to rotate relative to each other, and the end of the injection pipe 9 is provided with a baffle 91, which can ensure that the injection pipe 9 does not come off the flat plate 5 during the relative rotation of the two flat plates 5, and when the two flat plates 5 are rotated to an angle of 180°, the ball seat 51 is enclosed to form a whole ball groove and is in omni-directional rotation with the ball shaft 6. Moreover, the injection pipe 9 is a flexible hose, and after the flat plate 5 is leveled with the ground, the supply pipe 2 is rotated, the ball shaft 6 enables the supply pipe 2 to rotate freely, at this time, the injection pipe 9 is always connected to the ball shaft 6 and will only be bent due to the change of the rotation angle, and the injection pipe 9 can adapt to different angles of the ball shaft 6.

[0031] As a further provided embodiment of the utility model, a clamping piece 61 is further arranged on the ball shaft 6, and the ball shaft 6 has a working position in the movable stroke, in which the clamping piece 61 extends out of the supply pipe 2.

[0032] Specifically, the clamping piece 61 includes an arched portion with a pointed end facing the supply pipe 2, and the arched portion is bent under the drive of the clamping piece 61. The structure of the clamping piece 61 is shown in Figure 4 The supply pipe 2 is provided with a guide groove 22 for accommodating the clamping piece 61, and when the ball shaft 6 is pulled, the clamping piece 61 is driven to come out of the guide groove 22, and after losing the restriction of the guide groove 22, the clamping piece 61 is unfolded and extends out of the supply pipe 2, at this time, it is the working position, and the clamping piece 61 at the working position blocks the supply pipe 2, so that the ball shaft 6 is difficult to be retracted into the supply pipe 2. When the ball shaft 6 needs to be retracted, the clamping piece 61 is pressed, so that the arched portion is bent under the drive, and since the pointed end of the arched portion faces the supply pipe 2, the side surface of the arched portion is an inclined surface after being bent. When the ball shaft 6 is retracted into the supply pipe 2, the side surface of the arched portion is guided and slid by the inner wall of the guide groove 22 to further contract, so that the clamping piece 61 is retracted into the guide groove 22 and no longer interferes with the sliding of the ball shaft 6.

[0033] As a further provided embodiment of the utility model, a supporting rod 4 is further fixedly arranged on the supply pipe 2, and the flat plate 5 is fixedly provided with a fixed groove 53 for clamping the supporting rod 4.

[0034] Specifically, the flat plate 5 can be folded up for storage when not in use, and the end of the supporting rod 4 is provided with a protrusion corresponding to the fixing groove 53. When the flat plate 5 is used, the included angle between the flat plate 5 is 180°, at which time the end of the supporting rod 4 is clamped with the fixing groove 53, so that the swinging direction of the supply pipe 2 and the ball shaft 6 is consistent with the swinging direction of the supporting rod 4, and the operator can more conveniently force through the supporting rod 4. After the ball shaft 6 is pulled out, the distance between the upper half balloon 7 and the lower half balloon 8 is shortened, and the elastic force of the protruding part 10 is applied to the flat plate 5, so that the connection between the fixing groove 53 and the protrusion is more stable.

[0035] When the operator uses it, the flat plate 5 is placed on the ground, the supply pipe 2 and the ball shaft 6 are rotated to an appropriate angle, then the ball shaft 6 is pulled to fix the angle, and the angle between the supporting rod 4 and the flat plate 5 is also fixed, then the flat plate 5 and the ball shaft 6 are kept in the current state parallelly moved by pushing the handle 3, and the operation of filling and smoothing is carried out.

[0036] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
