Problems solved by technology

[0004] 1. The existing hanging cloth trolley has an arched portal frame that is similar to the tunnel arch surface. The arched portal frame is huge in size and the road passability is poor, which makes it difficult for the existing hanging cloth trolley to transfer;
[0005] 2. Since the tunnel arches that need to be constructed are not necessarily the same, the arched portal frame of the existing hanging cloth trolley cannot be applied to all tunnel arches, resulting in the poor versatility of the existing hanging cloth trolley, which improves the Manufacturing costs of construction equipment;
[0006] 3. Most of the existing hanging cloth operations are spread, nailed and glued manually. The degree of mechanization is low, not only the construction efficiency is low, but also the labor cost is increased.

Embodiment 1

[0033] A telescopic type valance vehicle, such as figure 1 Shown, a foldable cloth hanging carriage, such as figure 1 It is shown, comprising a chassis 2 for traveling in a tunnel. Generally in the tunnel are laying rails 1, 2 is provided with the chassis thus is driven by the travel motor running wheels, running wheels can be run along the rail 1, by means of a moving track. So Puwan a tarpaulin, the chassis 2 is moved some distance, then the tunnel cloth hanging operation surface of the lower section of the arch. Base is articulated telescopic arm 3, the telescopic arm 3 is connected with a cloth hanging frame 4. Specifically, the chassis 2 is fixed with the arm motor, the boom after the motor gear reducer, controlled by the control system enables the telescopic arm 3 rotates in the cross-sectional surface of the tunnel arch.

[0034] Such as figure 2 , In the present embodiment, the telescopic arm 3 is three telescopic boom sections, three sections in telescopic boom equipped w...

Embodiment 2

[0043] The technical solution in Example 1 is suitable for use in a tunnel having a circular arc shape or near the arc shape, and the diaplashes of many tunnels are combined with a plurality of different curvatures, with arc arch There is also an elliptical arc arch and a parabolic zone. For the large-length zone, the feedback control cycle of the control system in Example 1 is increased, resulting in a decrease in construction efficiency.

[0044] The arch faces of each tunnel have a rule of the arch curve, and the arch curve can be expressed in the form of a polar coordinate. Therefore, in the present embodiment, it is different from that of the first embodiment: the arm motor is a servo motor, and the servo motor can rotate the arrow angle of the three telescopic arms under the control of the control system. The two cylinders in the three telescopic arms are servo cylinders, and the servo cylinders drive three telescopic arms lower telescopic under the control of the control sy...

Embodiment 3

[0050] Unlike Example 2, in the present embodiment, the arm motor is a normal motor, and the two cylinders in the three telescopic arms are also ordinary cylinders. Since there is no servo system, this adjustment can reduce the procurement cost of the motor, cylinder, and control system. In addition, if Image 6 As shown, the hanging arrangement 4 is hinged to the telescopic arm 3, and the electric telescopic rod 6 is hinged between the hanging arrangement frame 4 and the telescopic arm 3, and the telescoping of the electric telescopic rod 6 is controlled by the control system. The hanging arrangement 4 is hinged to the telescopic arm 3, which increases a rotational degree of freedom to the hanging arrangement 4, and the distance between the pressure roller 43 and the inner wall of the tunnel, and the pressure of the pressure roller 43 on the inner wall of the tunnel can pass the electric telescopic rod. 6 is adjusted.

[0051] Specifically, when there is a pit in the tunnel arch s...

Abstract

A telescopic cloth hanging trolley comprises a chassis used for walking in a tunnel, a base is hinged to a telescopic arm, and the telescopic arm is connected with a cloth hanging frame. The telescopic arm can be driven by the control system to rotate and stretch out and draw back so that the cloth hanging frame can move in the circumferential direction of the tunnel arch face. The cloth hanging frame is used for hanging cloth and comprises a reel used for installing a waterproof cloth roll, a pressing roller used for pressing the waterproof cloth on the inner wall of a tunnel, a gluer and a movable nail gun, and the nail gun is used for nailing the waterproof cloth on the inner wall of the tunnel. Automatic cloth paving, nailing and gluing are achieved, the mechanical degree is high, the efficiency is high, and the labor cost is reduced. In addition, the trafficability is greatly improved, and the transition difficulty of the cloth hanging trolley is reduced. According to the cloth hanging control method, the rotation angle of the servo motor and the telescopic length of the servo oil cylinder are controlled by establishing a polar coordinate equation of a tunnel arch surface curve, so that the cloth hanging frame moves according to the curve determined by the polar coordinate equation. The control method has the advantages of high adaptability and high efficiency.

Description

Technical field [0001] The present invention relates to the field of tunnel construction equipment, particularly to a telescopic valance carriage further relates to a method of controlling a cloth hanging cloth hanging applied to the dolly. Background technique [0002] When excavation of the tunnel, the tunnel in order to prevent water leakage and prolong the life of the tunnel, we need to lay tarps on the inner wall of the tunnel. When hanging cloth work, we need to nail tarps nailed to the inner wall of the tunnel, and the seams between tarps were glue. [0003] At present, construction workers need the help of cloth hanging cloth car can be linked to the job. Application No. CN109356624A, CN110966024A prior patent discloses a cloth hanging carriage structure, the following problem existing cloth hanging carriage: [0004] 1, the conventional cloth hanging carriage having arched tunnel extrados close to the gantry, the gantry huge volume arch, by a difference of the road, so t...
