A kind of handling fixture for curved curbstone

Abstract

The present invention discloses a conveying fixture for curved curbstones, which solves the problem of how to safely and conveniently convey curved curbstones of various curvatures to designated locations for paving. A conventional clamping rod is designed to be divided into two sections, that is, a clamping head is hingedly connected to the conventional clamping rod through a pin shaft, so that the two clamping heads clamping the curbstones can be horizontally rotated at an angle relative to the clamping rod where they are located, and a length-adjustable half-mouth-shaped plug rod is arranged between the clamping rod and the clamping head. The half-mouth-shaped plug rod is composed of an L-shaped lead screw and an L-shaped sleeve screwed together, and the length is conveniently adjusted. The half-mouth-shaped plug rod is inserted between the clamping rod and the clamping head to ensure the stability of the clamping head, so as to adapt to the characteristics that the two sides of the curved curbstone are at both ends of an arc. At the same time, the central pin shaft of the fixture is designed to be in the form of a hollow pin shaft, and an L-shaped screw is screwed into the hollow hole of the hollow pin shaft. By dynamically adjusting the screw connection distance between the L-shaped screw and the hollow pin shaft and the rotation angle of the two clamping heads, the clamping of curved curbstones of various curvatures can be adapted.

Description

Technical Field

[0001] The invention relates to a transport clamp, in particular to a transport clamp for arc-shaped curbstones. Background Art

[0002] The curbstone is the boundary between the carriageway, sidewalk, green space, isolation belt and other parts of the road on the road surface, which plays a role in ensuring the traffic safety of pedestrians and vehicles and ensuring the neatness of the road edge. In the construction of ancillary projects of the road surface, the installation and construction of the curbstone mainly adopts cranes and forklifts for loading and unloading. Small forklifts cooperate with manual labor to carry out short-distance transportation of the curbstone, unload in sections according to the working surface, and then use manual labor for installation and construction. At present, there are many types of curbstones, and the weight of a single piece is very heavy. A curbstone weighs about 200 pounds. The shifting and installation requires the cooperation of many people, which is not only time-consuming and labor-intensive, but also has low installation efficiency. Moreover, during the installation process, it is easy to bump and collide, which not only increases the loss rate of the curbstone, but also often causes accidents of operators injuring their hands and feet. In particular, some projects have more curvatures of the road and need to install curved curbstones. How to safely and conveniently transport curved curbstones of various curvatures to the designated location for paving has become an urgent problem that needs to be solved on site. Summary of the invention

[0003] The invention provides a conveying fixture for curved curbstones, which solves the technical problem of how to safely and conveniently convey curved curbstones with various curvatures to designated locations for paving.

[0005] The overall concept of the present invention is: based on the structure of the traditional brick clamp for manual brick clamping, a creative process is carried out to redesign the traditional clamping rod into two sections, that is, a clamping head is hinged on the traditional clamping rod through a pin shaft, so that the two clamping heads clamping the curbstone can be horizontally rotated at an angle relative to the clamping rod where they are located, and a half-mouth-shaped plug rod with adjustable length is arranged between the clamping rod and the clamping head. The half-mouth-shaped plug rod is composed of an L-shaped lead screw and an L-shaped sleeve screwed together, and the length is easy to adjust. After being adjusted in place, it is inserted between the clamping rod and the clamping head to ensure the stability of the clamping head to adapt to the two sides of the curved curbstone. The surface has the characteristics of being at both ends of an arc. At the same time, the central pin shaft of the clamp is designed to be in the form of a hollow pin shaft, an internal thread is set in the hollow hole of the hollow pin shaft, and an L-shaped screw is screwed in the hollow hole of the hollow pin shaft. By dynamically adjusting the screw connection distance between the L-shaped screw and the hollow pin shaft and the rotation angle of the two clamping heads, it can adapt to the clamping of arc-shaped curbstones with various curvatures. The two clamping heads and L-shaped screw rods of the clamp of the present invention form a triangular clamp for the arc-shaped curbstone, which can conveniently and stably clamp the arc-shaped curbstone, and it is very convenient to adjust the clamping angle of furnace curbstones with different curvatures.

The left rear sleeve 17 is fixedly arranged on the front side of the right clamp rod 8. The left front sleeve 18 is arranged on the front side of the right clamp rod L-shaped clamp head 11. A half-mouth-shaped left front plug rod 19 is inserted between the left rear sleeve 17 and the left front sleeve 18. The left clamp rod L-shaped clamp head hinge pin 24 is arranged on the top surface of the lower end of the left clamp rod 7. The left clamp rod L-shaped clamp 12 is hinged on the hinge pin 24 of the clamp, and the right rear sleeve 20 is fixedly arranged on the front side of the left clamp rod 7. The right front sleeve 21 is arranged on the front side of the left clamp rod L-shaped clamp 12, and a half-mouth-shaped right front plug rod 22 is inserted between the right rear sleeve 20 and the right front sleeve 21; an internal thread is arranged in the hollow hole of the central pin shaft 16, and the inverted L-shaped screw 15 is screwed into the hollow hole with internal thread of the central pin shaft 16.

[0020] The structure of the half-mouth-shaped left front plug rod 19 is exactly the same as that of the half-mouth-shaped right front plug rod 22; the half-mouth-shaped left front plug rod 19 is composed of an L-shaped screw 26 and an L-shaped sleeve 27, and an internal thread is provided in the inner cavity of the L-shaped sleeve 27. The L-shaped screw 26 and the L-shaped sleeve 27 are screwed together to form a half-mouth-shaped plug rod; a left rubber anti-skid sheet 13 is provided on the clamping surface of the right clamping rod L-shaped chuck 11, and a right rubber anti-skid sheet 14 is provided on the clamping surface of the left clamping rod L-shaped chuck 12, and an arc-shaped curbstone 25 is clamped between the left rubber anti-skid sheet 13, the right rubber anti-skid sheet 14 and the inverted L-shaped screw 15; the left rubber anti-skid sheet 13 is provided on the clamping surface of the right clamping rod L-shaped chuck 12, and the right rubber anti-skid sheet 14 is provided on the clamping surface of the left clamping rod L-shaped chuck 12.

Because the curvature of most curved curbstones is large, the clamping force is mainly the interaction force between the two clamping heads, and the decomposed backward pressure is offset by the inverted L-shaped screw 15. Since the inverted L-shaped screw 15 is screwed together with the central pin 16, its connection force is sufficient to offset the backward component of force.
