Technical Field

[0001] This utility model relates to the field of embedded track construction equipment technology, specifically to an embedded track black glue injection trolley. Background Technology

[0002] In recent years, as subway operating hours have gradually increased, more and more lines will face renovation and upgrading, making the urban rail maintenance and renovation market a huge prospect. Embedded track is a fastener-free ballastless track technology. It forms an integral load-bearing structure by embedding the rails into concrete grooves, improving the smoothness and stability of the track. Elastic filling materials are used to directly fix the rails, eliminating the traditional fastener system and reducing vibration transmission.

[0003] Previously, the construction of embedded track black glue filling was mostly carried out by manually carrying the glue bucket and pouring it in. This method is difficult to control the amount of glue poured in, which easily contaminates the steel rails and track slabs, increases the difficulty and cost of later cleaning, and has low construction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an embedded track black glue injection trolley to solve the problems mentioned in the background art, such as the difficulty in controlling the amount of glue injected.

[0005] To achieve the above objectives, this utility model provides an embedded track black glue injection trolley for injecting black glue into the gap between the steel rail and the track slab of an embedded track. The trolley includes a vehicle body, a hopper, and a limiting component. The vehicle body includes a main body and wheels, with the wheels located at the bottom of the main body. The hopper includes a hopper body, a flow control valve, and a hopper support structure. The flow control valve is located at the outlet of the hopper body, and the hopper body is fixedly mounted on the hopper support structure. The hopper support structure is located on the main body, and its bottom is fixedly connected to the main body. The limiting component is located at the bottom of the main body and is used to guide the trolley in conjunction with the steel rail.

[0006] Furthermore, the discharge port of the hopper body includes a first discharge port and a second discharge port, the first discharge port extending to one side of the rail and the second discharge port extending to the other side of the rail.

[0007] Furthermore, the limiting component includes a first limiting component and a second limiting component, with the first limiting component located at the front end of the bottom of the vehicle body and the second limiting component located at the rear end of the bottom of the vehicle body.

[0008] Furthermore, the first limiting component includes a first limiting plate, a second limiting plate, a top plate, and a connecting plate. The first limiting plate and the second limiting plate are arranged opposite to each other, and the first limiting plate, the second limiting plate, and the top plate together form a U-shaped groove with an opening facing downwards. The first limiting plate and the second limiting plate are respectively attached to both sides of the rail so that the first limiting component can slide along the length direction of the rail. One end of the connecting plate is fixedly connected to the top surface of the top plate, and the other end of the connecting plate is fixedly connected to the main body of the vehicle body.

[0009] Furthermore, the first limiting plate is hinged to the top plate, and the second limiting plate is hinged to the top plate; the first limiting component also includes a threaded rod, which passes through the first limiting plate and the second limiting plate, and nuts are respectively provided on the threaded rod at positions corresponding to both sides of the first limiting plate and the second limiting plate.

[0010] Furthermore, the second limiting component has the same structure as the first limiting component.

[0011] Furthermore, there are two limiting components, namely a first limiting component and a second limiting component. The first limiting component is located at the front end of the bottom of the vehicle body, and the second limiting component is located at the rear end of the bottom of the vehicle body.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figures 1 to 5 As shown, an embodiment of this utility model provides an embedded track black glue injection trolley for injecting black glue into the gap between the steel rail 8 and the track plate of an embedded track. The trolley includes a vehicle body 1, a hopper 2, and a limiting component 3. The vehicle body 1 includes a body main 11 and wheels 12, with the wheels 12 disposed at the bottom of the body main 11. The hopper 2 includes a hopper body 21, a flow control valve 22, and a hopper support structure 23. The flow control valve 22 is disposed at the outlet of the hopper body 21. The hopper body 21 is fixedly mounted on the hopper support structure 23, which is located on the body main 11, and its bottom is fixedly connected to the body main 11. The limiting component 3 is disposed at the bottom of the body main 11 and is used to guide the trolley in conjunction with the steel rail 8.

[0035] In this embodiment, the discharge port of the hopper body 21 includes a first discharge port 24 and a second discharge port 25. The first discharge port 24 extends to one side of the rail 8, and the second discharge port 25 extends to the other side of the rail 8. The dual discharge ports extending to both sides of the rail allow for simultaneous filling on both sides, enabling a single operation to complete the filling of both sides of the rail, reducing manual back-and-forth movement, and significantly improving construction efficiency. In this embodiment, by setting a discharge port with a flow control valve, the flow rate and volume of the adhesive can be precisely adjusted, avoiding overflow of adhesive caused by manual dumping, which would contaminate the rails and road surface, and reducing subsequent cleaning costs. In this embodiment, the flow control valve 22 is a solenoid valve, including a wireless signal receiving module and a stepper motor-driven valve, with a valve opening adjustment accuracy of ±1%. The volume of the hopper body 21 is 5L, its inner surface roughness Ra≤0.8μm, and the angle between the discharge port and the vertical direction is 30°~45°.

[0036] like Figure 2As shown, the limiting component 3 includes a first limiting component 4 and a second limiting component 5, and the second limiting component 5 has the same structure as the first limiting component 4. The first limiting component 4 is located at the front end of the bottom of the vehicle body 11, and the second limiting component 5 is located at the rear end of the bottom of the vehicle body 11. In this embodiment, the dual limiting components form a front-to-back fitting and limiting layout, eliminating lateral movement of the vehicle body and ensuring that the discharge port is always accurately aligned with the filling grooves on both sides of the rail, thus avoiding contamination of the rail or track slab by black glue spillage caused by vehicle swaying.

[0037] like Figure 5 As shown, the first limiting component 4 includes a first limiting plate 31, a second limiting plate 32, a top plate 33, and a connecting plate 34. The first limiting plate 31 and the second limiting plate 32 are arranged opposite to each other, and together with the top plate 33, they form a U-shaped groove with an opening facing downwards. The first limiting plate 31 and the second limiting plate 32 are respectively attached to both sides of the rail so that the first limiting component 4 can slide along the length of the rail. One end of the connecting plate 34 is fixedly connected to the top surface of the top plate 33, and the other end of the connecting plate 34 is fixedly connected to the vehicle body 11. The first limiting plate 31 is hinged to the top plate 33, and the second limiting plate 32 is hinged to the top plate 33. The first limiting component 4 also includes a threaded rod 35, which passes through the first limiting plate 31 and the second limiting plate 32. Nuts are provided on the threaded rod at positions corresponding to both sides of the first limiting plate 31 and the second limiting plate 32. By screwing the corresponding nuts, they are made to press tightly against the two sides of the first limiting plate 31 and the two sides of the second limiting plate 32, thereby fixing the angle of the first limiting plate 31 and the second limiting plate 32, so as to adjust the distance between the openings of the first limiting plate 31 and the second limiting plate 32.

[0038] In this embodiment, the distance between the first limiting plate 31 and the second limiting plate 32 can be adjusted by tightening the nuts on both sides. A threaded rod 35 passes through the upper parts of the first limiting plate 31 and the second limiting plate 32 sequentially, and locking nuts are respectively installed on both sides of the first limiting plate 31 and the second limiting plate 32. When it is necessary to adjust the opening width between the two limiting plates, the operator can loosen the corresponding nuts one by one, allowing the first limiting plate 31 and the second limiting plate 32 to rotate independently around their hinge points with the top plate 33, thereby changing the distance between their ends. After adjustment, the nuts on each side are tightened again to press firmly against both sides of the limiting plate for fixation. This structure enables the linkage adjustment of the included angle of the limiting plate and the bottom spacing. The adjustment direction is a horizontal rotational movement centered on the hinge axis, allowing the ends of the limiting plates to move towards or away from each other, thus adapting to different specifications of steel rails 8. The adjustment range is controlled between 300 and 500 mm to adapt to common changes in rail width. The U-shaped groove structure fits the two sides of the steel rail 8, ensuring that the trolley travels strictly in a straight line along the length of the rail, avoiding grouting deviation.

[0039] In this embodiment, the limiting component 3 also includes a telescopic rod 36, which is vertically arranged. Its lower end is fixedly connected to the upper surface of the connecting plate 34, and its upper end is connected to the vehicle body 11. By changing the length of the telescopic rod 36, the entire limiting component 3 is driven to rise and fall vertically. When the telescopic rod 36 extends downward, the limiting component 3 moves downward, so that the U-shaped groove formed by the first limiting plate 31 and the second limiting plate 32 completely fits downward against both sides of the rail head of the steel rail 8, realizing the guiding function; when the telescopic rod 36 retracts upward, the limiting component 3 lifts up, so that the U-shaped groove completely detaches from the rail surface of the steel rail 8, facilitating the trolley to move laterally off the track or cross the track for transportation. The lifting stroke is reasonably designed and easy to operate, realizing the functional requirements of precise guidance during construction and rapid detachment during non-construction periods.

[0040] like Figure 1 As shown, the hopper 2 also includes a bucket rack 26 for placing the glue bucket 27, which is detachably fixed to the top edge of the hopper body 21. The bucket rack design allows for direct placement of the glue bucket, eliminating the need for manual bucket lifting and emptying. After the glue bucket 27 is opened, the support is tilted and placed on the bucket rack 26, allowing the glue to flow automatically into the hopper body 21 under gravity. This allows the filling trolley to operate continuously, avoiding interruptions in filling due to glue replenishment, thereby improving construction efficiency.

[0041] In this embodiment, the embedded track black glue injection trolley also includes a handrail 6, which is fixedly installed at the front end of the vehicle body 11. The grip portion of the handrail 6 is covered with an anti-slip rubber layer. The thickness of the anti-slip rubber layer is 3mm. The embedded track black glue injection trolley also includes a braking device and a brake control device 7. The braking device is a mechanical brake, and the brake control device 7 is a manual lever integrated on the handrail 6. The lever directly controls the brake caliper installed on the front swivel wheel via a steel wire. Turning the lever can drive the brake pads in the caliper to tightly clamp the wheel hub, achieving effective braking by using friction. This design has a simple structure, direct transmission, and can achieve rapid wheel locking, ensuring the trolley's parking safety on slopes. The wheels 12 include two swivel wheels and two directional wheels. The two swivel wheels are respectively located on both sides of the bottom of the vehicle body 11 near the handrail 6, and the two directional wheels are respectively located on both sides of the bottom of the vehicle body 11 away from the handrail 6. The omnidirectional wheels have a diameter of 150mm, and the directional wheels have a diameter of 200mm, with the wheels made of polyurethane-coated steel cores. The handrail 6 provides pushing control and an integrated braking control device 7, with an anti-slip layer ensuring safe grip. The wheels 12 adopt a front omnidirectional and rear directional layout, balancing steering flexibility and straight-line stability. The braking device enables rapid wheel locking. These three components form a closed-loop system of control, braking, and movement. Combined with the anti-slip handrail, this enhances human-machine safety. The linked braking response is rapid, making it particularly suitable for tunnel slopes. The combination of omnidirectional and directional wheels ensures flexible steering without deviating from the track, significantly improving construction efficiency and reducing operational risks.

[0042] In this embodiment, the workflow of the embedded track black glue injection trolley is as follows:

[0043] Step 1: Lower the limiting component 3 to the U-shaped groove on both sides of the rail 8, rotate the nuts on both sides of the first limiting plate 31 and the second limiting plate 32 to adjust the width of the U-shaped groove to match the rail 8, so that the first limiting component 4 and the second limiting component 5 at the front and rear ends of the vehicle body work together to lock the rail and form a straight guide.

[0044] Step 2: After opening the glue bucket 27, place it upside down on the detachable bucket frame 26. The black glue flows into the hopper body 21 by gravity. The discharge flow rate is preset by the solenoid valve type flow control valve 22, so that the discharge port is located on both sides of the steel rail 8, ensuring that the glue can flow to the filling grooves on both sides of the steel rail 8. Then, hold the handle 6 and push the trolley. The wheels 12 move along the track, and the black glue is simultaneously poured into the filling grooves on both sides of the steel rail 8 through the first discharge port 24 and the second discharge port 25.

[0045] Step 3: When encountering a slope or stopping, activate the brake control device 7 integrated into the handrail to lock the brake device of the linked wheel 12. After the grouting is completed, lift the connecting plate 34 to raise the limiting component 3 to the second preset position to disengage from the rail 8, and move the trolley out of the track area.
