Description

Technical Field

[0001] This utility model belongs to the technical field of crack repair tools, and specifically relates to a crack repair device for bridge crash barriers. Background Technology

[0002] Crash barriers primarily prevent vehicles from veering off the bridge and ensuring driver safety. However, due to environmental factors and age, they frequently develop cracks, which, if not repaired promptly, will affect their lifespan and functionality. Currently, maintenance personnel often simply apply adhesive tape and epoxy resin to both sides of the crack when repairing cracks in bridge crash barriers. This method is difficult to control in terms of repair thickness and results in construction waste. Furthermore, the outer side of the crash barrier is suspended above the river surface, limiting the ability of maintenance personnel to completely repair external cracks. Therefore, a new repair device is needed for repairing external cracks in bridge crash barriers. Utility Model Content

[0003] In view of the shortcomings of the prior art, this invention provides a device for repairing cracks in bridge crash barriers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bridge crash barrier crack repair device includes a movable upright, a sliding rod, a connecting rod, an adjusting screw, a threaded hole seat, a hand-cranked winch, a pulley, a sliding seat, a cable, a storage hopper, and a discharge pipe. One end of the connecting rod is fixedly connected to the upper part of the sliding rod, and the other end of the connecting rod is rotatably connected to the upper part of the upright. One end of the adjusting screw is rotatably connected to the upper part of the sliding rod, and the other end of the adjusting screw is connected to the upper part of the upright through a threaded hole seat. A hand-cranked winch is fixedly installed at the top of the upright, and the pulley is fixedly installed at the top of the sliding rod. The sliding seat is slidably installed on the sliding rod. The cable on the hand-cranked winch passes around the pulley and connects to the sliding seat. The storage hopper is fixedly connected to the sliding seat, and the bottom of the storage hopper is inclined downwards towards the upright and has a discharge pipe.

[0006] This utility model uses a double-pole (upright pole and sliding pole) structure to move the epoxy resin-filled storage hopper up and down using a hand-cranked winch, thereby achieving the coating and repair of cracks on the outside of the bridge crash barrier.

[0007] Furthermore, it also includes a spring and a sliding shaft. The storage hopper is rotatably connected to the sliding seat. A sliding shaft is provided between the upper part of the storage hopper and the sliding seat. The sliding shaft is fixed on the storage hopper, and the other end of the sliding shaft passes through the sliding seat. The spring is sleeved on the sliding shaft and applies an inward force to the storage hopper to ensure that the front end of the discharge pipe is in close contact with the anti-collision wall.

[0008] Furthermore, it also includes a rubber discharge nozzle and an elastic guide rod. The front end of the discharge pipe is detachably equipped with a rubber discharge nozzle, and the center of the rubber discharge nozzle is equipped with an elastic guide rod. The rubber discharge nozzle allows the flowing epoxy resin to adhere tightly to the surface of the anti-collision wall, while the elastic guide rod is used to perform preliminary repairs on the cracks. The elastic guide rod can guide the epoxy resin into the cracks.

[0009] Furthermore, the length of the upright is less than the length of the sliding rod. The function of the upright is to cooperate with the sliding rod and adjust the distance between the two by adjusting the bolts to clamp them onto the crash barrier. Therefore, the upright does not need to be too long.

[0010] Furthermore, the slide bar is composed of two rows of parallel square tubes. Square tubes are a common material with low purchase cost and can be used to make the main structure of the repair device.

[0011] Furthermore, the upper end of the storage hopper is provided with a hook hole. The function of the hook hole is to lift the storage hopper by pulling the hook when the rubber discharge nozzle is in close contact with the anti-collision wall and cannot move down freely, so that the rubber discharge nozzle leaves the wall.

[0012] Furthermore, the adjusting screw is located below the connecting rod, thereby adjusting the distance between the upright and the sliding rod.

[0013] Furthermore, it also includes a scraper, which is provided at the bottom of the front end of the discharge pipe to scrape and repair cracks in the epoxy resin flowing out of the discharge pipe.

[0014] The advantages of this utility model are as follows: This utility model solves the problem of inadequate repair of cracks on the outside of the bridge crash barrier by setting a sliding rod on the outside of the crash barrier and controlling the up and down movement of the storage hopper by a hand-cranked winch and sliding seat to repair the cracks on the wall surface, thereby improving the repair safety; at the same time, a rubber discharge nozzle and scraper are set at the front end of the discharge pipe to solve the problem of uneven repair thickness of cracks in the bridge crash barrier.

[0018] The present invention will now be described in detail with reference to the accompanying drawings:

[0019] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by "front", "rear", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the collector or element referred to must have a specific orientation, or a specific orientation structure and operation. Therefore, it should not be construed as a limitation of this utility model.

[0020] like Figure 1-3 As shown, a bridge crash barrier crack repair device includes a movable upright 1, a sliding rod 2, a connecting rod 3, an adjusting screw 4, a threaded hole seat 5, a hand-cranked winch 6, a pulley 7, a sliding seat 8, a cable 9, a storage hopper 10, a discharge pipe 11, a rubber discharge nozzle 14, an elastic guide rod 15, and a scraper 17. The upright 1 is made of double parallel square tubes, with the upper and lower ends of the square tubes welded together by connecting pieces. The sliding rod 2 is made of double-row, double-parallel square tubes, with four square tubes arranged in a rectangle, and the upper and lower ends of the square tubes welded together by connecting pieces. One end of the connecting rod 3 is fixedly connected to the upper part of the slide rod 2, and the other end of the connecting rod 3 is rotatably connected to the upper part of the upright rod 1. One end of the adjusting screw 4 is rotatably connected to the upper part of the slide rod 2, and the other end of the adjusting screw 4 is connected to the upper part of the upright rod 1 through the threaded hole seat 5. The adjusting screw 4 is located below the connecting rod 3. In this way, under the joint constraint of the connecting rod 3 and the adjusting screw 4, the distance between the upright rod 1 and the slide rod 2 can be adjusted by adjusting the adjusting screw 4. In use, the repair device can be clamped and locked onto the anti-collision wall by adjusting the distance.

[0021] A hand-cranked winch 6 is fixedly installed at the top of the upright 1. The pulley 7 is fixedly installed at the top of the slide rod 2. The sliding seat 8 is slidably installed on the slide rod 2 and is slidably installed between the square tubes. The cable 9 on the hand-cranked winch 6 passes around the pulley 7 and is connected to the sliding seat 8. The sliding seat 8 can be controlled to move up and down on the slide rod 2 by the hand-cranked winch 6.

[0022] The storage hopper 10 is fixedly connected to the sliding seat 8. A discharge pipe 11 is installed at the bottom of the storage hopper 10, tilted downwards towards the upright rod 1. A rubber discharge nozzle 14 is detachably installed at the front end of the discharge pipe 11. The rubber discharge nozzle 14 protrudes from the inner side of the sliding rod 2, and its front end is cut into an inclined ellipse with a slit at the elliptical opening. The rubber discharge nozzle 14 slides silently against the anti-collision wall surface with minimal friction. The slit at the front end of the rubber discharge nozzle 14 spreads the flowing epoxy resin to both sides. An elastic guide rod 15 is installed at the center of the rubber discharge nozzle 14 to guide the epoxy resin into the crack. A scraper 17 is installed at the bottom of the front end of the discharge pipe 11 to scrape the flowing epoxy resin evenly. The width of the scraper 17 is slightly smaller than the spacing between the inner square tubes of the slide bar 2. This spacing is the width of the epoxy resin coating, and the scraper 17 does not protrude from the inner side of the slide bar 2 (the side facing the upright). The spacing between the two is the thickness of the epoxy resin coating.

[0023] To ensure the rubber discharge nozzle 14 is tightly against the wall, a spring 12 and a sliding shaft 13 are also provided. The sliding shaft 13 is positioned between the upper part of the storage hopper 10 and the sliding seat 8. The sliding shaft 13 is fixed to the storage hopper 10, and its other end passes through the sliding seat 8. The spring 12 is fitted onto the sliding shaft 13. The spring force of the spring 12 is sufficient to ensure the rubber discharge nozzle 14 is tightly against the anti-collision wall without generating excessive pressure. To allow adjustment of the distance between the rubber discharge nozzle 14 and the wall in special circumstances, a hook hole 16 is provided at the upper end of the storage hopper 10, allowing the storage hopper 10 to be rotated at a small angle via the hook.

[0024] The operating principle of this method is as follows: The repair device is directly installed on the crack in the bridge crash barrier. The device is secured by adjusting the adjusting screw 4. The position of the storage hopper 10 is adjusted so that the elastic guide rod 15 is aligned with the crack opening. Then, epoxy resin is added to the storage hopper 10. The storage hopper 10 is moved up and down using the hand-cranked winch 6 to repair the crack in the bridge crash barrier. If the crack cannot be repaired by a single layer of epoxy resin, multiple layers can be applied to increase the coverage area.

[0025] Although the specific embodiments of this utility model have been described and explained in detail above, it should be noted that various changes and modifications can be made to the above embodiments, but these will not depart from the spirit of this utility model and the scope of the appended claims.
