Description

Technical Field

[0001] This utility model belongs to the technical field of construction tools, and in particular relates to a curbstone clamping and handling tool. Background Technology

[0002] When paving urban roads, if green belts are involved, curb stones need to be installed to separate the green belt side from the road side. The curb stones are rectangular in shape made of cement and are quite heavy, generally weighing 50-100kg, making them difficult for a single person to move. During installation, most of the curb stone is buried in the soil layer, with the upper part left above ground to act as a barrier and prevent soil from the green belt from being washed onto the road surface.

[0003] During the paving of curb stones, they are transported to the paving site by large trucks, and then manually carried one by one to the paving position. Due to the regular shape of the curb stones, hand-carrying them not only lacks a point of leverage, making it difficult to apply force, but also requires two people to carry them due to their weight. Current construction sites use wire to lift them, but this method makes it difficult to find a hanging point for the wire, and the wire is prone to falling during transport, posing a safety hazard. Therefore, this utility model utilizes construction tools on site, employing a welded assembly mechanism to easily clamp the curb stones and prevent them from falling off during transport. Utility Model Content

[0004] The purpose of this utility model is to provide a curbstone clamping and handling tool that, with the help of construction site tools, uses welding assembly tools to facilitate the clamping of curbstones and prevent them from falling off during handling.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A curbstone clamping and handling tool includes clamping plates for clamping two opposite ends of a curbstone. The clamping plates are plate structures, with the front of the clamping plate being the clamping side and a rubber layer installed on the corresponding clamping side. A sleeve is installed and fixed on the back of the clamping plate.

[0007] A single-sided clamping plate is equipped with a steel bar for lifting. The steel bar is bent into a rectangular structure. Both ends of the steel bar are inserted into the two openings of the sleeve, and the part of the steel bar inserted into the sleeve is rotatably engaged with the sleeve.

[0008] Furthermore, the back side of the clamping plate has a first plate and a second plate, the connection between the first plate and the second plate is perpendicular, and a sleeve is fixed at the connection. The first plate, the second plate and the clamping plate form a right-angled triangular structure.

[0009] Furthermore, the rubber layer is detachable and has a mounting plate on one side. A screw is vertically fixed in the center of the mounting plate. The clamping plate has a through hole for the screw to pass through, and the part of the screw that passes through the through hole is tightened and fixed by a nut.

[0010] The rubber layer has a groove in the width direction, the groove extends along the length direction, and the groove has a circular cross-section.

[0011] Furthermore, an arc-shaped plate is installed at the middle position corresponding to the reinforcing bars on both sides. The arc-shaped plate and the reinforcing bars on both sides are connected by a hinge. The hinge has a connecting part and a hinge sleeve located on both sides of the connecting part. The arc-shaped plate has a hinge shaft on both sides for the hinge sleeve to be fitted and hinged.

[0012] This utility model has the following beneficial effects: the bent end of the reinforcing bar forms a rotating shaft, which is inserted into the sleeve for the overall rotation of the reinforcing bar. The reinforcing bar serves as a lifting tool for the clamping plates on both sides. The overall structure is rectangular. When lifting, the corresponding parts of the reinforcing bars on both sides move towards the middle. The moving reinforcing bars are connected by steel cables, which makes it easy for workers to lift the bar by lifting. The steel cables connect the middle parts of the reinforcing bars on both sides. When lifting upward, the reinforcing bars exert force on the clamping plates towards the middle under the upward lifting force, thus completing the clamping and fixing of the curbstone.

[0017] The components represented by each number in the attached diagram are listed below: 1. Curbstone; 3. Clamping plate; 4. Rubber layer; 30. Sleeve; 2. Reinforcing bar; 31. First plate; 32. Second plate; 41. Mounting plate; 42. Screw; 33. Through hole; 43. Groove; 5. Arc plate; 6. Hinge; 51. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-3 As shown: A curbstone clamping and handling tool includes clamping plates 3 for clamping two opposing ends of a curbstone 1. The clamping plates 3 are plate structures, with the front of the clamping plate 3 serving as the clamping side, and a rubber layer 4 installed on the corresponding clamping side. A sleeve 30 is installed and fixed on the back side of the clamping plate 3. The clamping plates are rectangular, and during installation, the clamping sides are in contact with the side surfaces of the curbstone ends. The rubber layer increases the friction with the surface of the curbstone.

[0020] A single-sided clamping plate 3 is equipped with a lifting steel bar 2. The steel bar 2 is bent into a rectangular structure. Both ends of the steel bar 2 are inserted into the two openings of the sleeve 30, and the part of the steel bar 2 inserted into the sleeve 30 is rotatably engaged with the sleeve. The bent end of the steel bar forms a pivot, which is inserted into the sleeve for the overall rotation of the steel bar. The steel bar serves as a lifting tool for the clamping plates on both sides. The overall structure is rectangular. During lifting, the corresponding parts of the steel bars on both sides move towards the middle. The moving steel bars are connected by steel cables, which facilitates the lifting operation by the workers using a lifting bar. The steel cables connect the middle parts of the steel bars on both sides. When pulling upward, the steel bars, under the action of the upward pulling force, exert force on the other end of the clamping plate towards the middle, thus completing the clamping and fixing of the curb stone.

[0021] The clamping plate has a larger clamping surface, and the clamping sides have a deformable rubber layer, which improves the clamping firmness and prevents the curbstone from falling off during transportation. When the curbstone is released into the ground, the reinforcing bars are pushed to both sides. The reinforcing bars release the clamping force, automatically causing the clamping plate to detach, thus realizing the process of quickly clamping and removing the curbstone.

[0022] like Figure 2 As shown: The clamping plate 3 has a first plate 31 and a second plate 32 on its back side. The connection between the first plate 31 and the second plate 32 is perpendicular, and a sleeve 30 is fixed at the connection. The first plate 31, the second plate 32, and the clamping plate 3 form a right-angled triangular structure. This structure makes the clamping plate more stable, and the sleeve extends a short distance from the back side of the clamping plate, improving the stress stability of the clamping plate. This prevents the clamping plate from slipping off under gravity. The rubber layer 4 is detachable and has a mounting plate 41 on one side. A screw 42 is vertically fixed in the center of the mounting plate 41. The clamping plate 3 has a through hole 33 for the screw 42 to pass through. The part of the screw 42 passing through the through hole 33 is tightened with a nut. This facilitates the replacement of the aged, cracked, or severely worn rubber layer.

[0023] The rubber layer 4 has a groove 43 in the width direction and extends along the length direction. The groove 43 has a circular cross-section. This facilitates the deformation of the rubber layer after compression and improves the clamping force.

[0024] like Figure 3As shown: Arc-shaped plates 5 are installed at the midpoints of the reinforcing bars 2 on both sides. Each arc-shaped plate 5 has a hinge 6 connecting it to the reinforcing bars 2 on both sides. The hinge 6 has a connecting portion and hinge sleeves located on both sides of the connecting portion. The arc-shaped plates 5 have hinge shafts 51 on both sides for the hinge sleeves to fit and hinge together. The hinge sleeves on both sides of the hinge 6 respectively hinge the midpoints of the reinforcing bars and the hinge shafts of the arc-shaped plates. The arc-shaped plates are used for support during the lifting process, pulling the reinforcing bars to both sides.

[0025] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
