Description

Technical Field

[0001] The utility model relates to a positioning device for a tensioning slideway of a paver, belonging to the technical field of road administration equipment. Background Art

[0002] A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. The paving work is completed by the cooperation of various systems, mainly including the travel system, hydraulic system, and material distribution system. There are two main types of pavers, crushed stone pavers and asphalt concrete pavers. A crushed stone paver is a construction machine that can evenly spread crushed stone on the roadbed. It is mainly composed of a hopper, supporting rollers, a skid, a V-shaped scraper, a widened side plate, and a running wheel. An asphalt concrete paver is a machine that can evenly spread asphalt mixture on the road base and perform preliminary compaction and leveling. It is divided into crawler type and tire type. It consists of two parts: traction, paving, compaction, and ironing.

[0003] like Figure 4 The figure shows a schematic diagram of the structure of the tensioning slide position of a paver, the paver includes a bottom frame 14, a left side plate 1, a right side plate 2 and a tensioning slide 5 are provided on the bottom frame 14, the left side plate 1 and the right side plate 2 are symmetrically arranged about the tensioning slide 5, a front baffle 15 is provided at the front end of the paver, a left side mounting surface 3 is provided on the left side plate 1, and a right side mounting surface 4 is provided on the right side plate 2.

[0004] The left mounting surface 3 and the right mounting surface 4 are both cutting surfaces, and the plane on the tensioning slide 5 is a processing surface, which is required to be coplanar with the left and right mounting surfaces, with a flatness of ≤1.0, to ensure that the forward and backward sliding force of the left and right feed tensioning wheels on the processing surface of the tensioning slide 5 is uniform and reliable.

[0005] One end of the tensioning slide 5 is fixed on the front baffle 15, and the other end of the tensioning slide 5 is fixed on the bottom frame 14. The positional relationship between the tensioning slide 5 and the mounting surfaces on both sides is three-dimensional, and it is impossible to accurately locate it by measuring and marking. In order to change this situation, it is urgent to invent a special positioning device for the tensioning slide. Utility Model Content

It utilizes square steel pipes, reference blocks and magnetic devices to make the left and right side plate surfaces coplanar with the middle processing surface of the tensioning slideway to be installed, so that the complex three-dimensional spatial position relationship between the workpieces is concretized. One-time assembly can ensure the flatness requirements of the installation surfaces on both sides and the processing surfaces of the tensioning slideway after spot welding. There is no need for repeated marking and measurement, which reduces the labor intensity of the operator, reduces the workpiece positioning time, and improves the production efficiency and the workpiece assembly accuracy.

[0010] A further improvement of the utility model is that the magnetic block is a switch-type magnetic seat, which is adsorbed to the positioning surface of the magnetic device through a tightening slideway of the magnetic seat, and the operation is simple and reliable.

[0011] A further improvement of the utility model is that by adjusting the processing amount of the second reference block, the lower surfaces of the two planar positioning plates are made coplanar with the lower plane of the magnetic seat, and the flatness is ≤1.0, so as to meet the requirement that the flatness of the upper surface of the tensioning slideway and the two left mounting surfaces and the right mounting surface structural surface is ≤1.0.

[0012] A further improvement of the utility model is that the plane positioning plate and the reference block are mounted on both ends of the square steel pipe through hexagon socket bolts, and the disassembly and assembly structure is simple and has high reliability.

[0013] A further improvement of the utility model is that anti-slip plates are installed on both end surfaces of the square steel pipe to prevent the utility model from slipping.

[0014] A further improvement of the utility model is that the anti-dropping plate is installed at both ends of the square steel pipe through hexagon socket bolts.
