When the electric push rod 8 that is fixed on the central shaft retracts, promote sliding sleeve 3 and make the wheel support arm rotate, and drive wheel is pressed on the pipeline wall along with the motion of wheel support arm. When the motor 14 rotates, it is driven by the synchronous belt mechanism 15, so that the traction vehicle frame 1 travels in the pipeline. When the electric push rod 8 stretches out, the sliding sleeve 3 pulls the wheel supporting arm along with the retreat of the electric push rod 8 so that the driving wheel breaks away from the pipe wall.

The main body of the B-section counterpart, as shown in Figure 4, is functionally divided into a counterpart working part 18 and a walking part behind it. The column is connected with the sliding sleeve. Viewed from the Z direction, the three pairs of sliding columns and sliding sleeves are evenly distributed on the circumference. The cylinder 23 pushes the sliding column 19 through the connecting plate 22 so that the counterpart working part can move relative to the running part. The self-propelled part has a cylindrical cage frame 21, and two crawler-type traveling wheels 24, two crawler-type driving wheels 25, two brake blocks 26 and two crawler-type traveling wheels 24 are arranged in sequence along the Z-axis direction on the frame, The radial distribution is shown in Figure 5. The angle between the two road wheels is 120° and is symmetrical about the Y axis. The angle between the two driving wheels (two brake blocks) is also 120° and is symmetrical about the Y axis. The driving wheel The included angle with the walking wheel is 60°. 4 road wheels are installed directly on the frame. Two drive wheels are installed on one end of drive wheel support arm 31 by bearing pin respectively, and drive wheel support arm can rotate around the rotary shaft that is fixed on the vehicle frame, and the other end of support arm is connected with sliding sleeve 29 by hinge. The air motor 32 is installed on the frame, the air motor shaft, the wheel support arm rotary shaft and the driving wheel shaft are equipped with sprockets, and the power is transmitted from the air motor to the driving wheel through the chain drive.

The air storage tank 39 of section C provides compressed air, and the radial distribution of the rollers 40 on it is shown in FIG. 7 , and the included angle of each wheel is also 120° and is symmetrical about the Y axis.

Section D can self-propelled downhill security car, as shown in Figure 8, including a cylindrical cage frame 41, a hollow shaft 45 in the center of the frame, and a sliding sleeve 46 that can slide outside, and the transmission mechanism is arranged symmetrically around the hollow shaft . This car is powered by battery 43, and controller 43 controls, and the winch 55 driven by servo motor 56 is installed.

The drive wheel 44 is installed on one end of the drive wheel support arm 51 through a pin shaft, the drive wheel support arm can rotate around the rotary shaft fixed on the vehicle frame, the other end of the support arm is connected with the sliding sleeve 46 through a hinge, and the motor 53 is installed on the drive On the wheel support arm, drive by synchronous belt drive mechanism 52, vehicle frame is installed 3 cover driving wheels and support arm thereof. The brake block 48 is installed on one end of the brake block support arm 47 through a pin shaft, the brake block support arm can rotate around the rotary shaft fixed on the vehicle frame, the other end of the brake block support arm is connected with the sliding sleeve 46 through a hinge, and the vehicle frame is installed 3 sets of brake shoes and their support arms. The radial distribution of each drive wheel and brake block is shown in Figure 9, and the three drive wheels (three brake blocks) are evenly distributed radially and symmetrical about the Y axis.

If the electric push rod 54 fixed on the center frame stretches out to the right, the sliding sleeve 46 is promoted and the wheel support arm is rotated, the driving wheel is pressed on the pipe wall along with the movement of the wheel support arm, and the brake block 48 is disengaged. pipe wall. When the motor rotates 53, it is driven by the synchronous belt mechanism 52, so that the traction vehicle frame 41 travels in the pipeline. When the electric push rod 54 retreats, it drives the sliding sleeve 46 to move to the left, and the pulling wheel support arm makes the driving wheel break away from the pipe wall. If the sliding sleeve continues to move to the left, the brake shoe is pressed on the pipe wall along with the movement of the brake shoe support arm, so that the walking device is stopped.

When each section is combined, the hoist of the uphill safety guarantee vehicle in section A is tightened, and section A and section B are close together; the two sections of BC are connected by a hinge; the hoist on section D is tightened, and section D and section C are tightly connected. Lean together.

When the uphill slope is relatively large, in order to ensure the safe walking of the entire engineering vehicle, in the first step, the brake block 26 of section C is pressed against the pipeline wall, so that the entire engineering vehicle stops in the pipeline; in the second step, the uphill safety guarantee vehicle Walk forward autonomously, the hoist 16 puts the steel cable, and the BCD three sections do not move. When the uphill safety guarantee vehicle travels to the end of the pipeline, the connecting rod 11 will extend the claw 10 out of the pipeline under the action of the spring force and block the edge of the pipeline. Go up, the proximity switch 12 output control signal on the connecting rod 11 makes the uphill safety guarantee vehicle stop walking simultaneously, and hoist 16 also stops putting steel cable; The 3rd step, BCD three sections walk upwards jointly, and hoist 16 receives steel cable simultaneously. Because the winch 16 has a fast self-locking device similar to the safety belt of a car, when there is a downward trend of the BCD three sections, the steel cable on the uphill safety guarantee car of section A can pull the three sections behind, thereby ensuring the entire project The car will not slide down into the depths of the pipe.

When the downhill slope is relatively large, in order to ensure the safe walking of the entire engineering vehicle, in the second step, the brake block 48 of the D section is pressed against the pipeline wall, so that the downhill safety guarantee vehicle stops in the pipeline; in the second step, the B section with Walk along the AC section, and simultaneously the hoist 55 puts the steel cable, because the fast self-locking device similar to the safety belt of the car is arranged on the hoist, when there is a downward trend of the ABC three sections, the steel cable on the D section downhill safety guarantee car can be Pull the front three sections to ensure that the entire engineering vehicle will not slip into the depths of the pipeline. In the 3rd step, the ABC three sections walk to the pipeline mouth target position and then stop, the brake block 48 of the D section downhill safety guarantee vehicle releases, the driving wheel 44 works and walks downward, and the hoist 55 receives the steel cable simultaneously.

In other cases, the combination may not be separated.
