Description

Technical Field

[0001] The present invention relates to the field of tunnel maintenance, and in particular to a spraying trolley.

[0002] The present invention also relates to a method for using the spray trolley. Background Art

[0003] Currently, tunnel maintenance requires the use of a tunnel maintenance spray trolley. The existing technology uses a spray system welded to the trolley frame as a whole. The trolley sprays while it moves, and the trolley needs to repeatedly lay tracks during movement, which is cumbersome to operate and requires high ground flatness. The tunnel needs to be sprayed back and forth, so the trolley needs to move back and forth as a whole. The trolley is large and difficult to control. The spraying part is prone to contact with the inner wall of the tunnel during movement, causing damage to the concrete structure of the tunnel wall that is not fully dried, affecting the flatness of the tunnel structure. The existing technology spray system cannot move independently, and the spray range is consistent with the longitudinal length of the spray, which is a small longitudinal range. Summary of the Invention

[0004] The purpose of the present invention is to optimize and improve the above problems and provide a spray trolley that can realize fully automatic spraying, making spraying faster, and the trolley frame is fixed after moving into position, that is, the trolley frame does not need to move as a whole. After starting the spray system, the spray system moves back and forth along the spray track to automatically spray, with flexible spraying, stable speed and good spraying effect.

[0005] For the technical topic of a spray trolley, it includes:

[0006] Slide pipes are arranged along the length of the trolley and located on both sides of the trolley;

[0007] A slide tube tie rod, which connects the slide tubes on both sides into a whole;

[0008] The guide wheel is vertically arranged on the slide tube pull rod through a guide wheel support. Two vertically spaced guide wheels are arranged on one guide wheel support, and are respectively located above and below the slide tube pull rod;

[0009] Sprinkler pipe racks are arc-shaped and arranged along the tunnel cross section;

[0010] A vertical rod, used for erecting the spray pipe rack;

[0011] a base fixed to the lower ends of the vertical rods located on both sides of the trolley;

[0012] The travel wheel has a pin connected to the base and adapted to the slide tube so that the base can move along the slide tube;

[0013] The fixed base is fixed to the lower end of the vertical rod in the middle position.

[0014] A sprocket box is provided on the trolley and has a built-in sprocket;

[0015] The chain is passed through the sprocket and guide wheel in the sprocket box, and is laid out in a circle along the length of the trolley and fastened to the fixed base to drive the fixed base to move;

[0016] The motor is arranged on the outside of the sprocket box, and its driving shaft extends into the sprocket box to drive the sprocket and drive the fixed base to move, so that the spray pipe rack can move along the length direction of the trolley.

[0017] Such a structure enables the spray pipe rack to move back and forth on the trolley, and the spray pipe rack can be moved without moving the trolley, thereby improving the tunnel maintenance efficiency.

[0018] As a further improvement of the spray trolley, the sliding pipe includes a first sliding pipe section located at both ends and a second sliding pipe section located in the middle of the sliding pipe, and the first sliding pipe section and the second sliding pipe section are spliced ​​together.

[0019] With such a structure, the first sliding pipe section and the second sliding pipe section can be spliced ​​together to extend the sliding range.

[0020] As a further improvement of the spray trolley, the spray pipe rack includes two parallel arc tubes and one spray pipe. The arc tubes and the spray pipe are arranged in a triangular position, with two arc tubes at the bottom and the remaining spray pipe mounted on the top. The two arc tubes below are welded into a whole through a connecting plate, and the connecting plate is fixed to the vertical rod below it. The spray pipe is used to connect to the water pipe inlet; nozzles are distributed at intervals on the spray pipe, and the spray pipe is mounted on the arc tube by a fixed bracket.

[0021] The use of such a structure is conducive to stable water spray maintenance, among which the nozzles are made of copper nozzles with good quality.

[0022] As a further improvement of the spray trolley, the front end and the rear end of the chain are respectively fastened to the front and the rear end of the fixed base by tensioning bolts.

[0023] With such a structure, the tensioning bolts can be loosened or tightened, making disassembly and assembly convenient.

[0024] As a further improvement of the spray trolley, a portal beam is provided between the sliding pipe and the trolley, and a base is provided on the portal beam for erecting the sliding pipe.

[0025] As a further improvement of the spray trolley, the trolley is provided with a water tank, the water tank is provided with a water outlet, the water outlet is provided with a water outlet switch, the water outlet switch is connected to the booster pump, and the booster pump is connected to the water pipe to supply water.

[0026] As a further improvement of the spray trolley, the water tank is further provided with a water inlet and a cleaning port, the water outlet is provided with a water outlet filter, the fixed bracket is passed through by a steel wire rope, and a water pipe is hung on the steel wire rope.

[0027] As a further improvement of the spray trolley, active walking wheel frames are provided at the lower part of both sides of the trolley. The active walking wheel frames include a reducer, which has a drive shaft mounted on a bearing. The drive shaft passes through the tire to drive the tire to rotate. A shaft sleeve is provided between the tire and the bearing.

[0028] As for the use of the spray trolley, start the motor to drive the sprocket in the sprocket box to rotate, which drives the chain to move. Then the chain pulls the fixed base, and the fixed base drives the spray pipe rack to move through the vertical rod on it. The vertical rods on both sides of the spray pipe rack drive the base below it, so that the traveling wheels under the base can reciprocate along the length of the sliding pipe. During the reciprocating movement, water is injected into the spray pipe rack to carry out tunnel maintenance.

[0029] As a further improvement to the method of using the spray trolley, when the portion of the chain located on the upper guide wheel passes through both the fixed base and the sprocket box, after the chain and the fixed base are released, the vertical rod is pushed to switch the spray pipe rack on it between the front and rear ends of the trolley. After the switching is completed, the chain is reconnected to the sprocket in the sprocket box and then re-fastened to the fixed base. After restarting the motor, the reciprocating motion of the spray pipe rack at the front and rear ends of the trolley can be switched.

[0030] Or when the portion of the chain located at the lower guide wheel passes through the sprocket box, and the portion of the chain located at the upper guide wheel does not pass through the sprocket box, the motor can be directly started to make the spray pipe rack reciprocate between the front and rear ends of the trolley.

[0031] The present invention has the following advantages: 1. It can adopt wireless remote control, and the spraying system can move forward and backward automatically; 2. The spraying range is large, with a longitudinal length of 12 meters; 3. The frame structure is simple; 4. It moves automatically and there is no need to repeatedly lay tracks.
