Description

Technical Field

[0001] The utility model belongs to the field of curbstone construction, in particular to a positioning device for curbstone paving. Background Art

[0002] In the current municipal road construction, the paving of prefabricated curbstones mainly uses hanging wires to control the position of the outer edge of the curbstone. Since the wires are elastic and easily misplaced, the position of the curbstone needs to be constantly adjusted when it is placed, and the gap between two adjacent curbstones is also mainly based on the construction workers' feelings and actual operation experience. Therefore, the existing curbstone paving method is prone to uneven outer edges, poor smoothness, and different installation seam widths.

[0003] The patent with a publication date of 2022-03-29 and application number CN202122076225.3 discloses a positioning device for curbstones or flat stones. When in use, this positioning device needs to frequently pick up and re-place the entire device according to the paving progress, which is inconvenient to use and increases the workload of construction workers.

[0004] Based on this, the present application provides a positioning device for curb paving that is simpler to use and does not require frequent picking up and repositioning of the entire device. Utility Model Content

[0005] The utility model aims to solve the technical problems existing in the prior art. To this end, the utility model provides a positioning device for paving curbstones.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A positioning device for paving a curbstone is provided, comprising a movable seat and a positioning partition which is movably arranged at the front end of the movable seat; the movable seat comprises side panels arranged at both sides of the curbstone and a horizontal shaft with multiple rollers arranged at the front and rear ends of the top of the curbstone; a positioning stop is arranged on the inner side of the side panel located at the back of the curbstone, and the positioning stop extends out of the front end of the side panel; a first connecting beam is arranged at the front end of the movable seat and located in front of the two side panels, and a guide rod is arranged on the first connecting beam; a connecting plate is arranged on the top of the positioning partition, and a sleeve rod is welded on the connecting plate, and the sleeve rod is movably sleeved on the guide rod.

[0008] Preferably, the positioning stop is provided with a plurality of through holes along its length direction, and a universal ball is embedded in each through hole.

[0009] Preferably, the length of the positioning stop extending out of the front end of the side panel is at least 1 / 3 of the length of the curbstone.

[0010] Preferably, the guide rod and the sleeve rod are positioned and plugged in using concave and convex grooves.

[0011] Furthermore, the guide rod is sleeved with a spring, and the spring is welded to the first connecting beam.

[0012] In a preferred embodiment, a pad is provided on the inner side of the side panel located behind the curb, the pad does not extend beyond the front end of the side panel, and the curb is located between the positioning stop and the pad. Preferably, the pad is also provided with a plurality of through holes along its length, and a universal ball is also embedded in each through hole.

[0013] Preferably, the positioning stop and the cushion strip are both made of angle steel, and the positioning stop and the cushion strip are both fixed to the side plate by screws.

[0014] In a preferred embodiment, the bottom of the positioning stop and cushion strip is provided with a guide wheel that is in rolling contact with the curb.

[0015] In a preferred embodiment, a second connecting beam is provided at the rear end of the movable seat in front of the two side plates, and a fixing rod is provided on the second connecting beam for holding the fixing rod to push the movable seat.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The positioning partition of the utility model can be moved out of the gap between the two curbs by the vertical movement of the sleeve rod on the guide rod, so as not to interfere with the movement of the moving seat, and there is no need to take out the whole equipment and then reinstall it. During the construction process, it is only necessary to operate the sleeve rod to control the positioning partition, and the moving seat can move on the curb following the paving process of the curb, which is more convenient, labor-saving and can effectively improve the paving speed of the curb;

[0018] Second, the positioning stopper integrated with the moving seat can play a good role in positioning the outer edge of the curb. Compared with the through-line positioning method, the positioning stopper is more reliable. BRIEF DESCRIPTION OF THE DRAWINGS
