Abstract
The invention discloses an electric heating device for rushing to repair damaged road surfaces rapidly. The electric heating device for rushing to repair damaged road surfaces rapidly comprises a support body (1) and a plurality of electric heating bars (2) arranged on the outer periphery of the support body (1); and the outer end surfaces, which are far away from the support body (1), of the electric heating bars (2) form spherical profiles. The electric heating device can be used for solving the technical problems that the existing electric heating device is inconvenient to transport and install.
Description
Technical field
The invention belongs to field of electric heating, particularly a kind of electric heater unit for rapid rush-repair distressed pavements.
Background technology
In the construction on rapid rush-repair road surface, a kind of method is wherein had to be the repairing utilizing precoated silica sand composite material rapid curing to realize distressed pavements.This emergency repair method is spread in a large number by rapid curing precoated sand to spill in distressed pavements place and to bury electric heater unit underground wherein, opens electric heater unit and make the precoated sand rapid curing that is heated realize the repairing of distressed pavements during work.
Electric heater unit of the prior art is the electrical heating frame that traditional electrically heated rod or spiral heating are excellent or arrange in length and breadth, and it is directly embedded in distressed pavements inside; For large area distressed pavements, then need to arrange longer or wider above-mentioned electric heater unit, and longer or wider above-mentioned electric heater unit all can bring very large inconvenience for transport and installation.
Summary of the invention
For this reason, technical problem to be solved by this invention is that the existing electric heater unit for rapid rush-repair distressed pavements is not easy to transport and the problem of installing, and then provides a kind of being convenient to transport and the electric heater unit installed.
For solving the problems of the technologies described above, the present invention discloses a kind of electric heater unit for rapid rush-repair distressed pavements, and it comprises: supporter, and is arranged at the multiple electrical bars on described supporter outer peripheral face; The profile that described electrical bar is formed in the outer face away from described supporter is spherical.
Above-mentioned electric heater unit also comprises the catch on the outer face being arranged at described electrical bar; The area of described catch is greater than the cross-sectional area of described electrical bar; The profile that multiple described catch is formed is spherical.
In above-mentioned electric heater unit, the gap length between adjacent described catch is less than the diameter of described electrical bar.
In above-mentioned electric heater unit, described supporter is cylindrical or spherical.
In above-mentioned electric heater unit, described catch is arc-shaped flaky, and the profile that multiple described catch is formed is spherical.
In above-mentioned electric heater unit, electrical connection in parallel between described electrical bar.
Technique scheme of the present invention has the following advantages compared to existing technology:
(1) the present invention adopts spherical electric heater unit, and it can roll on the ground, compared to transport existing electric heater unit with install more convenient; And its electrical bar arranged adds the contact area with precoated sand, enhances heating effect.
(2) further, the present invention also arranges catch at electric heater unit on the outer face of electrical bar, and it increases the heating surface area with precoated sand further, convenient transport simultaneously; Further, when between catch, gap is less than electrical bar diameter, its hidden danger that can also prevent other electrical bars do not arranged in this electric heater unit of catch from inserting inside and interfere with each other.
Accompanying drawing explanation
In order to make content of the present invention be more likely to be clearly understood, below according to a particular embodiment of the invention and by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is the cross section structure schematic diagram of electric heater unit.
In figure, Reference numeral is expressed as:
1-supporter 2-electrical bar 3-catch 21-outer face.
Detailed description of the invention
Fig. 1 is the electric heater unit for rapid rush-repair distressed pavements of the present invention, and it comprises: supporter 1, and the supporter 1 in the present embodiment is spherical; And the multiple electrical bars 2 be arranged on described supporter 1 outer peripheral face; Described electrical bar 2 inserts in described supporter 1, and the profile that described electrical bar 2 is formed in the outer face 21 away from described supporter 1 is spherical.
This electric heater unit also comprises the catch 3 on the described outer face 21 being arranged at described electrical bar 2; Described catch 3 is arc-shaped flaky; The area of described catch 3 is greater than the cross-sectional area of described electrical bar 2; Gap length between adjacent described catch 3 is less than the diameter of described electrical bar 2.The profile that multiple described catch 3 is formed is spherical.
Multiple described electrical bar 2 mutually electrical connection in parallel is arranged, and it is connected with power supply respectively, temperature controller of also connecting in electric loop; During work, switched on power by the plug of electric wire one end, temperature controller will control the temperature of described electrical bar 2 automatically, and described catch 3 is heated simultaneously.Like this, after the precoated sand contacted with described electric heater unit reaches solidification temperature, rapid curing realizes the reparation of distressed pavements.
As a kind of embodiment that can replace, in other embodiments, described supporter 1 can also be other shapes such as cylindrical barrel.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
