Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
As shown in fig. 1, in the rolling brush attaching system based on the radian of the wall surface of the tunnel, an arm support 9 is a folding frame, a rolling brush 7 is hinged to the end portion of the arm support 9, and a swing angle oil cylinder 6 for adjusting the angle of the rolling brush 7 is hinged between the rolling brush 7 and the arm support 9.
The reversing valve 1 is an electromagnetic valve, an oil inlet of the reversing valve 1 is connected with a high-pressure oil source, an oil return port of the reversing valve 1 is connected with an oil tank, and an oil outlet of the reversing valve 1 is respectively connected with a hydraulic lock 3 and a flow distributing and collecting valve 2. Two oil outlets of the hydraulic lock 3 are correspondingly connected with a one-way throttle valve I5.1 and a one-way throttle valve II 5.2; the one-way throttle valve I5.1 is connected with the small cavity of the swing angle oil cylinder 6, and the one-way throttle valve II 5.2 is connected with the large cavity of the swing angle oil cylinder 6. Two oil outlets of the flow distributing and collecting valve 2 are correspondingly connected with a floating retaining valve I4.1 and a floating retaining valve II 4.2; the floating maintaining valve I4.1 is connected with the small cavity of the swing angle oil cylinder 6, and the floating maintaining valve II 4.2 is connected with the large cavity of the swing angle oil cylinder 6.
As shown in fig. 2, the floating holding valve i 4.1 and the floating holding valve ii 4.2 are identical in structure, and the floating holding valve i 4.1 is taken as an example: the floating holding valve I4.1 comprises a two-position three-way cone valve 4.11 and an electric proportional overflow valve 4.12, and the two-position three-way cone valve 4.11 and the electric proportional overflow valve 4.12 are connected in parallel.
The working principle is as follows:
a job preparation state:
the change valve 1 (YV 1 or YV2 is electrified) enters oil from the port P, returns oil from the port T, and hydraulic oil enters the change valve 1 from the port P, enters the small cavity of the swing angle oil cylinder 6 through the hydraulic lock 3 and the one-way throttle valve I5.1, and enters the large cavity of the swing angle oil cylinder 6 through the hydraulic lock 3 and the one-way throttle valve II 5.2. Two return circuits increase one-way choke valve I5.1 and one-way choke valve II 5.2 respectively, ensure that the action is more accurate, can reduce the shake amount of round brush 7 simultaneously. In the initial stage of the cleaning state of the rolling brush, the hydraulic oil drives the rolling brush 7 through the two loops to perform preliminary adjustment to achieve the operation preparation posture.
And (3) starting operation:
after the posture of the roller brush is adjusted to the right position, the reversing valve 1 (YV 1 and YV2 are not electrified) returns to the middle position, hydraulic oil is supplied from a P1 port, enters the floating retaining valve I4.1 and the floating retaining valve II 4.2 through the flow distributing and collecting valve 2 respectively, and then enters a large cavity and a small cavity of the swing angle oil cylinder 6 respectively. The floating maintaining valve (the floating maintaining valve I4.1 and the floating maintaining valve II 4.2) is formed by connecting a two-position three-way cone valve 4.11 and an electric proportional overflow valve 4.12 in parallel (as shown in figure 2), the floating pressure of the large cavity and the small cavity of the oil cylinder can be adjusted and set (at the moment, YV3 is electrified) through the electric proportional overflow valve 4.12 of the floating maintaining valve (the floating maintaining valve I4.1 and the floating maintaining valve II 4.2), so that a large cavity and a small cavity are formed and are supported by proper floating pressure, when the rolling brush 7 meets an obstacle, the rolling brush 7 feeds back the force to the swing angle oil cylinder 6, and the large cavity or the small cavity of the oil cylinder can realize automatic expansion and contraction under back pressure, thereby completing the self-adaptive swing of the rolling brush.
And (3) finishing the operation:
after the operation is finished, the YV3 is de-energized, the floating holding valve I4.1 and the floating holding valve II 4.2 are closed, the reversing valve 1 is reversed (the YV1 or the YV2 is energized) to withdraw the arm support, the rolling brush is swung to the horizontal state, and the recovery work of the operation arm is finished.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
