Description

Technical Field

[0001] The utility model belongs to the technical field of pavement maintenance, and particularly relates to a highway subgrade pavement maintenance construction equipment. Background Technique

[0002] Generally, a marking construction device is used on the highway subgrade pavement to draw pavement markings. In order to play a role in guiding and diverting vehicles, the form of drawing a diversion line is generally adopted. For example, white V-shaped lines or diagonal lines are set at locations such as over-wide, irregular or complex driving condition intersections, ramp entrances of grade-separated intersections, etc., indicating that vehicles must drive according to the specified route and are not allowed to press or cross the line.

[0003] In order to re-draw the faded white V-shaped lines on the road surface, a marking construction device is required. The existing marking construction device has the following disadvantages in the use process: when drawing white V-shaped lines, manual spraying devices are generally held manually for manual drawing, and two-step drawing is required. Generally, the left side is drawn first and then the right side is drawn, so that the V-shaped lines are formed, lacking a structure that can be formed at one time, resulting in low drawing efficiency. Therefore, a highway subgrade pavement maintenance construction equipment is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a highway subgrade pavement maintenance construction equipment to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A highway subgrade pavement maintenance construction equipment, including a mobile trolley, a paint tank is fixedly connected to the top of the mobile trolley, two symmetrically arranged pushing hand rods fixedly connected to the top of the mobile trolley are arranged on the left side of the paint tank, a material pump fixedly connected to the top of the mobile trolley is arranged on the right side of the paint tank, the feed port of the material pump is communicated with the inside of the paint tank through a pumping pipe, the discharge port of the material pump is fixedly communicated with a three-way pipe, the two discharge ports of the three-way pipe are respectively fixedly communicated with a straight pipe through a telescopic hose, the bottom ends of the straight pipes are fixedly communicated with spraying pipes, and a plurality of discharge ports at the bottom of the two spraying pipes are fixedly communicated with inclined nozzles;

[0006] It also includes a rapid prototyping transmission structure and a folding positioning structure. The rapid prototyping transmission structure is installed on the two straight pipes and is connected to the mobile trolley. The rapid prototyping transmission structure can enable the construction equipment to spray the road surface markings in a V-shaped structure at one time;

[0007] The folding positioning structure is installed on the top of the mobile trolley and is connected to the rapid prototyping transmission structure. The folding positioning structure can fold and vertically fix the rapid prototyping transmission structure on the mobile trolley.

[0008] As a preferred embodiment, the rapid prototyping transmission structure includes an M-shaped bracket rotatably connected to the front end of the mobile trolley. Two symmetrically arranged U-shaped guide rods are fixedly connected to the bottom end of the M-shaped bracket. A transmission rod is slidably sleeved outside the two U-shaped guide rods. Two guide blocks with a cross-section in the shape of a work are slidably connected in the guide grooves opened on the transmission rod. The guide blocks are fixedly connected to the outside of the straight pipe. The M-shaped bracket is movably sleeved outside the two straight pipes through the opened V-shaped channels.

[0009] As a preferred embodiment, both ends of the M-shaped bracket are rotatably connected to the rotation grooves provided at the top of the mobile trolley through rotating shafts.

[0010] As a preferred embodiment, an electric telescopic rod is fixedly connected to the middle of the bottom end of the mobile trolley. A locking block is fixedly connected to the telescopic end of the electric telescopic rod. A hand-tightening screw is movably inserted into the middle of the transmission rod.

[0011] As a preferred embodiment, the folding positioning structure includes two symmetrically arranged positioning seats fixedly connected to the top of the mobile trolley. The cross-sections of the positioning seats are all in the shape of a U. Pins are movably inserted into the positioning seats.

[0012] As a preferred embodiment, two symmetrically arranged jacks are opened on the M-shaped bracket. The jacks are all matched with the pins.

[0013] Compared with the prior art, the highway subgrade and pavement maintenance construction equipment provided by the present utility model has at least the following beneficial effects:

[0014] In the present utility model, when using the highway subgrade and pavement maintenance construction equipment, first, the equipment is pushed to the highway subgrade and pavement area where the V-shaped line needs to be marked. By starting the material pump, the paint in the paint tank is pumped to a plurality of nozzles provided at the bottom of the two spraying pipes for spraying. At the same time, by starting the electric telescopic rod, the transmission rod is pushed to move away from the mobile trolley. Since the two straight pipes move in the V-shaped channels and cooperate with the two guide blocks, when the two spraying pipes move away from the mobile trolley, they also move away from each other, so as to realize the marking of the V-shaped marking at one time, greatly improving the efficiency of the maintenance construction. Moreover, when it is necessary to fold the M-shaped bracket perpendicular to the mobile trolley, the hand-tightening screw can be loosened, and at this time, the fixed connection relationship between the locking block and the transmission rod is cancelled, so that the M-shaped bracket can be rotated upward through the two rotating shafts to be folded perpendicular to the mobile trolley. In addition, the two pins are also pulled out and reinserted into the jacks to form the folding fixation of the M-shaped bracket, so that when the construction equipment is not in use, the space occupied by the equipment can be greatly reduced.

[0022] Embodiment

[0023] In order to be able to re-paint the faded white V-shaped lines on the road surface, a marking construction device needs to be used. The existing marking construction devices have the following disadvantages in the use process: When painting white V-shaped lines, manual spraying devices are generally held manually by workers for manual painting. Two-step painting is required, usually painting the left side first and then the right side, so that the V-shaped lines are formed. There is a lack of a structure that can be formed in one step, resulting in low painting efficiency;

[0024] For this reason, please refer to Figures 1-3, the present utility model provides a highway subgrade and pavement maintenance construction device, including: a mobile trolley 1, a paint tank 2 is fixedly connected to the top of the mobile trolley 1, two symmetrically arranged push rods 3 fixedly connected to the top of the mobile trolley 1 are provided on the left side of the paint tank 2, a material pump 4 fixedly connected to the top of the mobile trolley 1 is provided on the right side of the paint tank 2, the inlet of the material pump 4 is connected to the inside of the paint tank 2 through a suction pipe 41, the outlet of the material pump 4 is fixedly connected to a tee pipe 42, two outlets of the tee pipe 42 are respectively fixedly connected to a straight pipe 44 through a telescopic hose 43, the bottom ends of the straight pipes 44 are fixedly connected to spraying pipes 45, and a plurality of outlets at the bottom of the two spraying pipes 45 are fixedly connected to inclined nozzles 46. The plurality of spraying pipes 45 provided at the bottom of the two spraying pipes 45 are inclined, so that the middle tip of the V-shaped line can be aligned during spraying;

[0025] It further includes a rapid prototyping transmission structure 5 and a folding positioning structure 6. The rapid prototyping transmission structure 5 is installed on the two straight pipes 44 and is connected to the mobile trolley 1. The rapid prototyping transmission structure 5 can enable the construction device to spray the road marking of the V-shaped structure at one time;

[0026] The folding positioning structure 6 is installed on the top of the mobile trolley 1 and is connected to the rapid prototyping transmission structure 5. The folding positioning structure 6 can fold and vertically fix the rapid prototyping transmission structure 5 on the mobile trolley 1.

[0027] Furthermore, as Figures 1-3 shown, specifically, in order to enable the V-shaped line to be scribed and formed at one time, the rapid prototyping transmission structure 5 is provided to include an M-shaped bracket 51 rotatably connected to the front end of the mobile trolley 1. The bottom end of the M-shaped bracket 51 is fixedly connected with two symmetrically arranged U-shaped guide rods 52. The same transmission rod 53 is slidably sleeved outside the two U-shaped guide rods 52. Two guide blocks 54 with a cross-section in the shape of a work are slidably connected in the guide grooves opened on the transmission rod 53. The guide blocks 54 are fixedly connected to the outside of the straight pipe 44. The M-shaped bracket 51 is movably sleeved outside the two straight pipes 44 through the opened V-shaped channel 55. Both ends of the M-shaped bracket 51 are rotatably connected to the rotation grooves provided at the top of the mobile trolley 1 through rotating shafts 511. The middle part of the bottom end of the mobile trolley 1 is fixedly connected with an electric telescopic rod 58. The telescopic end of the electric telescopic rod 58 is fixedly connected with a locking block 56. A hand-tightening screw 57 is movably inserted in the middle of the transmission rod 53. One end of the hand-tightening screw 57 is threadedly connected to the screw hole provided on the locking block 56.

[0028] Wherein, the diameter of the straight pipe 44 is equal to the width of the V-shaped channel 55 to avoid crosstalk. Two through holes matching with the hand-tightening screw 57 are opened in the middle of the transmission rod 53. At the same time, a screw hole matching with one end of the hand-tightening screw 57 is provided at the end of the locking block 56 away from the electric telescopic rod 58. The structure is simple and not shown in the drawings.

[0029] Furthermore, as shown in Figures 1-3 , it is worth specifically explaining that in order to enable each component on the M-shaped bracket 51 to be foldably and vertically fixed on the mobile cart 1 when the device is not in use, a folding positioning structure 6 is provided, which includes two symmetrically arranged positioning seats 61 fixedly connected to the top end of the mobile cart 1. The cross-section of each positioning seat 61 is in a U-shaped structure. A pin 62 is movably inserted into each positioning seat 61. Two symmetrically arranged jacks 63 are opened on the M-shaped bracket 51, and the jacks 63 are all matched with the pins 62.

[0030] Among them, when the M-shaped bracket 51 is folded vertically to the mobile cart 1, the M-shaped bracket 51 is movably sleeved by the two positioning seats 61, and the positions of the pins 62 are aligned and coincident with the jacks 63.

[0031] In summary: When using this highway subgrade and pavement maintenance construction device, first push the device to the highway subgrade and pavement area where the V-shaped line needs to be drawn, and start the material pump 4, then extract the paint in the paint tank 2 to the multiple nozzles 46 provided at the bottom of the two spraying pipes 45 for spraying. At the same time, by starting the electric telescopic rod 58, push the transmission rod 53 to move away from the mobile cart 1. Since the two straight pipes 44 move in the V-shaped channel 55 and cooperate with the two guide blocks 54, when the two spraying pipes 45 move away from the mobile cart 1 and move away from each other, the V-shaped marking can be drawn at one time, greatly improving the efficiency of the maintenance construction. Furthermore, when it is necessary to fold the M-shaped bracket 51 vertically to the mobile cart 1, the hand-tightening screw 57 can be loosened. At this time, the fixed connection relationship between the locking block 56 and the transmission rod 53 is cancelled, so that the M-shaped bracket 51 can be rotated upward through the two rotating shafts 511 to be folded vertically on the mobile cart 1. In addition, the two pins 62 are also pulled out and reinserted with the jacks 63 to form the folding and fixing of the M-shaped bracket 51, so that when the construction device is not in use, the space occupied by the device can be greatly reduced.
