Description

Technical Field

[0001] This utility model relates to a protective door, and more particularly to a safety protective door for a maintenance vehicle's guide discharge chute. Background Technology

[0002] Asphalt pavement maintenance vehicles are specialized vehicles used for the maintenance and repair of asphalt pavements. They are typically equipped with efficient sweeping systems and efficient asphalt mixture heating and mixing devices. The asphalt mixture is heated and mixed in the mixing tank, and then evenly spread on the damaged pavement to achieve rapid and efficient pavement repair. To facilitate the distribution of the mixture onto the pavement, a guide groove is hinged to the discharge chute of the mixing tank. However, this hinged guide groove may flatten and extend beyond the width of the vehicle during bumpy conditions. To address this risk, a safety plate is screwed onto the left side panel of the discharge chute. When the maintenance vehicle is in operation, the safety plate needs to be removed, and the screws securing the safety plate are very easy to lose. Opening and closing the safety plate is also cumbersome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a safety protection door for the guide discharge chute of a maintenance vehicle. This solves the problem that the existing mixing tank discharge chute has a hinged guide groove, which may flatten out and extend beyond the width of the vehicle when bumpy. In order to solve this risk, a safety plate is screwed to the left side plate of the discharge chute. However, when the maintenance vehicle is working, the safety plate needs to be removed, and the screws that fix the safety plate are very easy to lose. Opening and closing the safety plate is also troublesome.

[0004] The technical solution adopted by this utility model to solve the above-mentioned problems is as follows:

[0005] A safety door for a maintenance vehicle's guide discharge chute includes a traction chassis 1, a mixing box 2, a discharge chute 3, a guide groove 4, a left side plate 5, and a rectangular through hole 501. The mixing box 2 is fixedly installed at the front of the traction chassis 1. The discharge chute 3 is installed at the lower left of the mixing box 2. The guide groove 4 is hinged to the left side of the discharge chute 3. The left side plate 5 is installed on the left side of the mixing box 2 and is fixedly connected to the traction chassis 1. A rectangular through hole 501 is opened at the lower part of the left side plate 5, and the guide groove 4 can extend out of the rectangular through hole 501.

[0006] It also includes a tool lock 6, a door panel 7, a racket-shaped through hole 701, and a handle 8. The door panel 7 is placed at the rectangular through hole 501 on the left side panel 5. The racket-shaped through hole 701 is opened at the bottom of the door panel 7. The tool lock 6 is fixedly installed at the racket-shaped through hole 701 on the door panel 7, and the locking tongue on the tool lock 6 can be inserted into the lower right side of the left side panel 5. The handle 8 is hinged to the left side of the door panel 7.

[0007] Support plates A9 are fixedly installed on the lower front and rear sides of the right side wall of the door panel 7, support plates B10 are fixedly installed on the middle front and rear sides of the right side wall of the door panel 7, support plates C11 are fixedly installed on the middle front and rear sides of the door panel 7, and each support plate C11 is fixedly connected to the left side panel 5. L-shaped plates A12 are fixedly installed on the upper front and rear sides of the door panel 7, and each L-shaped plate A12 is fixedly connected to the left side panel 5. The right side of each support plate A9 is hinged to a tension plate 13, and each tension plate 13 is hinged to... The upper adjacent support plates C11 are hinged in the middle. The right side of each support plate B10 is hinged to an L-shaped plate B14. The upper part of each L-shaped plate B14 is hinged to the lower part of the upper adjacent L-shaped plate A12. The right side of each support plate C11 is hinged to a pneumatic spring 15. Each pneumatic spring 15 is hinged to the upper part of the upper adjacent L-shaped plate B14. This facilitates the raising and lowering of the door plate 7 by means of support plate A9, support plate B10, support plate C11, L-shaped plate A12, tension plate 13, L-shaped plate B14, and pneumatic spring 15.

[0008] The handle 8 is fitted with a handle assembly 16, which includes a question mark-shaped plate 1601, a pull rod 1602, a support rod 1603, and a rubber sleeve 1604. The question mark-shaped plate 1601 is hung on the handle 8. The pull rod 1602 is fixedly installed at the lower part of the question mark-shaped plate 1601. The support rod 1603 is fixedly installed on the front and rear sides of the right side wall of the pull rod 1602, respectively. The right side of each support rod 1603 is fixedly fitted with a rubber sleeve 1604. The handle 8 is pulled by the handle assembly 16 to prevent the handle 8 from pinching the hand.

[0009] The working principle of this utility model is as follows: The traction chassis drives the mixing tank, discharge chute, guide chute, left side plate, tool lock, door panel, handle, support plate A, support plate B, support plate C, L-shaped plate A, tension plate, L-shaped plate B, pneumatic spring, and handle assembly to the road surface that needs repair. The tool lock is opened with a key, and the locking tongue on the tool lock moves away from the left side plate. The handle assembly is then removed from the cab, and the question mark-shaped plate is attached to the lower part of the handle. The rubber sleeve is attached to the door panel. The pull rod is pushed upwards, and the pull rod directly or indirectly drives the question mark-shaped plate, support rod, and rubber sleeve. The question mark-shaped plate drives the handle upwards, and the handle drives the door panel, which in turn directly or indirectly moves the handle upwards. The tool lock, support plate A, and support plate B are moved upwards. During this process, the pneumatic spring pushes the L-shaped plate B upwards, and the L-shaped plate B rotates counterclockwise around the L-shaped plate A. The L-shaped plate B drives the support plate B to move upwards, the support plate B drives the door panel, the door panel drives the support plate A, and the support plate A drives the tension plate to rotate counterclockwise around the middle of the support plate C. The door panel rises to a suitable height, and the question mark-shaped plate drives the handle assembly away from the handle. The guide groove rotates counterclockwise, and the guide groove rotates around the discharge groove to a suitable position. The guide groove extends out from the rectangular through hole, and the rotation of the guide groove stops. The mixture in the mixing tank is discharged through the discharge groove and the guide groove.

[0010] After the work is completed, rotate the guide groove clockwise. The guide groove rotates around the discharge chute to the appropriate position. Stop rotating the guide groove, attach the question mark-shaped plate to the upper part of the handle, and attach the rubber sleeve to the door panel. Pull the lever down. The lever directly or indirectly drives the question mark-shaped plate, support rod, and rubber sleeve. The question mark-shaped plate drives the handle downward. The handle drives the door panel. The door panel directly or indirectly drives the tool lock, support plate A, and support plate B downward. During this process, L-shaped plate B compresses the pneumatic spring downward. L-shaped plate B rotates clockwise around L-shaped plate A. L-shaped plate B drives support plate B downward. Support plate B drives the door panel. The door panel drives support plate A. Support plate A drives the tension plate to rotate clockwise around the middle of support plate C. The door panel descends to the initial position. The question mark-shaped plate drives the handle assembly away from the handle. Close the tool lock with the key. The latch on the tool lock is close to the left side panel. Put the handle assembly back into the cab and tow the chassis away from the repaired road surface.

[0011] The advantages of this utility model are: 1. It facilitates opening and closing the door panel. 2. The handle assembly prevents the handle from pinching the hand. Attached Figure Description
