Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to a curbstone and flat stone clamping device for road engineering construction. Background Art

[0002] During road construction, curb stones, flat stones, and kerb stones are often used for construction. However, the commonly used flat stones and curb stones are large in size and heavy in weight, which makes them inconvenient to carry manually. In addition, they are easy to hit or crush hands during transportation, which increases construction risks. The commonly used construction method is also to carry them by forklift, but during transportation, flat stones are easy to fall from the fork arm of the forklift, causing them to break and damage, affecting the aesthetics of the road after construction.

[0003] Some existing flat stone clamping devices, such as the Chinese patent CN220335655U, mainly move the outer column upward, drive the transmission slider to move closer to the middle, and drive the right-angle clamping block to clamp the flat stone. However, during construction and use, when the outer column is driven downward, it is easy to increase the pressure of the right-angle clamping block on the ground, and the right-angle clamping block will sink into the ground, affecting the reverse movement of the slider, resulting in poor effect when the right-angle clamping block is opened, which seriously affects the efficiency of clamping and transporting flat stones. Utility Model Content

[0004] In view of the problems existing in the background technology, the utility model proposes a curbstone and flat stone clamping device for road engineering construction, which drives the opening and clamping of the clamping member by hingedly connecting the first arm and the second arm, thereby increasing the opening and clamping speed of the clamping member and improving the clamping and handling efficiency of the flat stone.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a curbstone and flat stone clamping device for road engineering construction, comprising a first arm and a second arm hinged to each other in a V-shaped structure, the first arm and the second arm are respectively hinged to a first clamping member and a second clamping member plumb downward, the first clamping member and the second clamping member are fixedly connected by a telescopic rod that can be telescopically slidable, and when the first arm and the second arm rotate, the telescopic rod can be driven to extend, and the first clamping member and the second clamping member can be driven to move in the opposite direction and open;

[0006] Furthermore, the first arm and the second arm are bent to form a gripping portion and a hinged portion, and the first arm and the second arm are hinged through the tail end of the hinged portion, and the first clamping member and the second clamping member are hinged to the hinged portion of the first arm and the second arm away from the tail end; when the gripping portion is placed horizontally, the hinged portion of the first arm and the second arm is tilted to form a V-shaped structure;

[0007] Furthermore, the first clamping member and the second clamping member are inverted T-shaped structures, with a clamping plate provided at the lower end and claw teeth configured on the inner side of the clamping plate.

[0008] Beneficial effects of the utility model: When the utility model is in use, the first and second arms can be held to drive the first clamping member and the second clamping member to open and clamp. Since the first clamping member and the second clamping member are respectively hinged to the first and second arms, the first and second arms can be rotated in the opposite direction to drive the first and second clamping members to open and clamp, thereby increasing the opening and clamping speed of the clamping members. During the rotation of the first and second arms, the first and second clamping members will not be subjected to too much downward pressure, thereby preventing the first and second clamping members from sinking into the ground, thereby increasing the efficiency of clamping and carrying flat stones.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0016] In the attached figure, direction A is plumb downward, and direction B is horizontal to the right.

[0017] See also Figures 1 to 5The device for clamping curbstones and flat stones for road engineering construction shown in the figure comprises a first arm 1 and a second arm 2 which are hinged to each other in a V-shaped structure, the first arm 1 and the second arm 2 being respectively hinged with a first clamp 3 and a second clamp 4 which are plumb downwardly supported, and the first clamp 3 and the second clamp 4 are fixedly connected by a telescopic rod 5 which can be telescopically slid. When the first arm 1 and the second arm 2 are rotated outward and opened, the telescopic rod 5 can be driven to extend, and the first clamp 3 and the second clamp 4 can be driven to move outward in opposite directions and open. When the first arm 1 and the second arm 2 are rotated inward and folded, the first clamp 3 and the second clamp 4 can be driven to move inward, showing a clamping tendency. When the utility model is in use, two people can hold the first arm 1 and the second arm 2 respectively, and drive the first clamp 3 and the second clamp 4 to clamp the flat stone 6 (such as Figure 2 When two people carry the flat stone 6 and lift the first arm 1 and the second arm 2, the first arm 1 and the second arm 2 have a tendency to rotate and fold inward, so that the first clamping member 3 and the second clamping member 4 move inward, clamping the flat stone 6 more firmly and preventing the flat stone 6 from falling.

[0018] like Figure 2 The first arm 1 and the second arm 2 are bent to form a gripping portion 201 and a hinged portion 202, and the first arm 1 and the second arm 2 are hinged at the tail end of the hinged portion 202, and the first clamping member 3 and the second clamping member 4 are hinged on the hinged portion 202 away from the tail end of the first arm 1 and the second arm 2 (as shown in FIG. Figure 1 When the holding parts of the first arm 1 and the second arm 2 are placed horizontally, the hinge parts 202 of the first arm 1 and the second arm 2 are tilted to form a V-shaped structure. When the first arm 1 and the second arm 2 are configured to form an angle of the V-shaped structure as shown in the figure, rotating within the angle range can drive the relative movement of the first clamping member 3 and the second clamping member 4 faster, thereby increasing the opening and clamping speed of the first clamping member 3, so as to improve the clamping and handling efficiency of the flat stone 6.

[0019] like Figure 4 The first clamping member 3 and the second clamping member 4 are shown as inverted T-shaped structures, with a clamping plate 302 at the lower end. The clamping plate 302 is welded with two connecting rods 301 with plumb bobs pointing upward. The upper ends of the two connecting rods 301 are hinged to the first support arm 1 or the second support arm 2, and a connecting plate 304 is provided between the two connecting rods 301. The two ends of the telescopic rod 5 are fixedly connected to the connecting plates 304 opposite to the first clamping member 3 and the second clamping member 4, and are used to guide the first clamping member 3 and the second clamping member 4 to move away from or closer to each other. The inner side of the clamping plate 302 is constructed with claw teeth 303. In the process of clamping the flat stone 6, the claw teeth 303 can be used to buckle the bottom of the flat stone 6 (such as Figure 2 As shown), it is convenient to lift and carry the flat stone 6.

[0020] When the utility model is in use, two people can hold the first arm 1 and the second arm 2 respectively, and cooperate with each other to fold or spread and rotate the first arm 1 and the second arm 2 to drive the first clamp 3 and the second clamp 4 to spread and clamp. Since the first clamp 3 and the second clamp 4 are respectively hinged to the first arm 1 and the second arm 2, the first clamp 3 and the second clamp 4 are driven to spread and clamp by rotating the first arm 1 and the second arm 2 in the opposite direction, and the spreading and clamping speed of the clamp can be increased. In the process of rotating the first arm 1 and the second arm 2, too much pressure will not be applied to the first clamp 3 and the second clamp 4 to plumb downward, so that the first clamp 3 and the second clamp 4 are prevented from sinking into the ground, so as to improve the clamping and handling efficiency of the flat stone 6. In addition, the utility model has a simple structure, is easy to produce and manufacture, and can be popularized and used.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
