Description

Paver screed heating device and paver

Technical Field

The utility model relates to a paver screed heating device to and the paver including this screed heating device.

Background

The paver is a construction equipment for paving various materials of a road base layer and a road surface layer. When the paver is used for paving various materials, a screed plate of the paver, which is a key structural part of the paver, is preheated firstly. The traditional heating modes are three, namely liquefied gas combustion heating, oil liquid combustion heating and heating rod heating. And because a large amount of polluting gases are generated during combustion heating of liquefied gas and oil, the heating rod is not beneficial to environmental protection and energy conservation, so that the heating rod heating mode is more and more widely applied in recent years.

When the heating rod is adopted to heat the screed plate of the paver, the structure of the heating rod is thin and narrow, so that the phenomenon that the screed plate is heated unevenly is easy to occur when the heating rod heats the screed plate. The contact part of the heating rod and the ironing plate is heated too fast, and the edge and the middle part are heated too slowly and too little.

When the screed plate is heated unevenly, galling is easy to occur, namely, various paved materials are bonded at the edge position of the screed plate of the paver which is heated too slowly and too little. This phenomenon may result in uneven paving, which may seriously affect the paving quality of the paving machine.

Detailed Description

Fig. 1 shows a top view of a paver screed heating apparatus 100 in accordance with one embodiment of the present disclosure. As shown in fig. 1, the paver screed heating apparatus 100 includes a heating unit 1. The heating unit 1 comprises a first heating rod 10 and a second heating rod 20 arranged on a paver screed 2. The first heating rod 10 and the second heating rod 20 each include a first rod 30 having a long bar shape or a long rod shape, and second rods 40 disposed at both ends of the first rod 30. The second stick 40 is preferably perpendicular to the first stick 30. The first and

second heating rods

10 and 20 are constructed in a square structure with an opening 32 by the first and

second rods

30 and 40.

In a preferred embodiment, the first heating rod 30 and the second heating rod 40 are provided as an electric heating rod or an infrared heating rod. The heating device is more beneficial to accurately controlling the heating temperature and the heating time, is also beneficial to reducing pollution and meets the requirement of environmental protection.

As shown in fig. 1, the first heating rod 10 is configured to be inserted into the opening 32 of the second heating rod 20 such that the second rods 40 of the first heating rod 10 and the second heating rod 20 are alternately arranged, thereby configuring the heating unit 1 in a substantially "t" shape. Thus, the area enclosed by the heating unit 1 has two first rods 30 and four second rods 40 perpendicular to the first rods 30. The first rod bodies 30 and the second rod bodies 40 which are arranged in two different directions are heated together, so that the paver screed 2 in the area surrounded by the heating unit 1 can be uniformly heated, and the phenomenon of galling caused by nonuniform heating of the paver screed 2 is avoided.

Meanwhile, the heating unit 1 is arranged at the geometric center of the paver screed 2, so that the heating uniformity of all positions of the whole paver screed 2 can be further ensured.

In a preferred embodiment, the paver screed heating apparatus 100 comprises a plurality of heating units 1. The plurality of heating units 1 are uniformly arranged along the longer side of the ironing board 2 in the lateral or longitudinal direction, or are uniformly arranged along both the lateral and longitudinal directions of the ironing board 2. Therefore, when the size of the ironing plate 2 is too large, the working personnel can set different numbers of heating units 1 according to the specific size of the ironing plate so as to ensure that the ironing plate 2 can be uniformly heated.

In addition, by adjusting the lengths of the first rod 30 and the second rod 40, the size of the area surrounded by the heating unit 1 can be controlled. It will be readily appreciated that the smaller the area enclosed by the individual heating units 1, the more favourable the uniform heating of the screed 2. Therefore, the first rod body 30 and the second rod body 40 with different lengths are selected according to actual requirements, and the requirement that the ironing plate 2 is uniformly heated is met.

As shown in fig. 1, a first gap 25 is provided between the first rod 10 and the second rod 40 of the thermal unit 1, which are adjacent to the first heating rod 20; a second gap 35 is formed between the first rod 30 of the first heating rod 10 and the second rod 40 of the second heating rod 20; meanwhile, a third gap 45 is provided between two adjacent heating units 1. By means of the arrangement, different heating rods (namely the first heating rod 10 or the second heating rod 20) and different heating units 1 can be guaranteed not to be in contact, so that damage to the heating rods due to overheating caused by contact of the heating rods or the heating units 1 is avoided, and further the paver screed heating device 100 is prevented from being out of work.

As shown in fig. 1, at least one first connection 28 is arranged in said first gap 25. The first connecting member 28 is used for fixedly connecting the first heating rod 10 and the second heating rod 20, and prevents the first heating rod 10 and the second heating rod 20 from being dislocated under the action of external force, which results in the failure of the heating device 100.

Similarly, at least one second connector 48 is disposed on the first rod 30 of the first heating rod 10 and the second heating rod 20. The second connecting member 48 can play a reinforcing role, so that the first rod 30 is more stably connected to the screed 2.

Fig. 2 shows a top view of a paver screed heating apparatus according to another embodiment of the present disclosure. As shown in fig. 2, a plurality of third rods 50 extending parallel to the second rods 40 are disposed at intervals on the first rods 30 of the first and

second heating rods

10 and 20. Thus, by arranging any number of third bars 50 within a certain range, the density of the third bars 50 in the heating unit 1 can be adjusted. Thereby, the uniformity of the heating of the paver screed 2 may be further improved. Meanwhile, the distance between two adjacent third rod bodies 50 is set to be larger than the diameter of the third rod body 50, so that the first heating rod 10 can be normally inserted into the second heating rod 20.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and should not be construed as limiting the present invention in any way. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing examples, or that equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
