Description

Technical Field

[0001] This utility model belongs to the technical field of slope protection concrete lining machine, and in particular relates to a composite anti-derailment roller device. Background Technology

[0002] Slope protection concrete lining machines are key equipment used for pouring concrete on slopes in water conservancy projects and road construction. Their roller system needs to maintain stable operation in complex terrain. In existing technologies, the rollers are mostly cylindrical guide rollers with rims on both sides, placed directly on steel rails for travel. However, with the diversification of construction environments (such as soft foundation slopes and areas with high elevation differences), track misalignment can easily cause the rollers to derail, seriously affecting construction safety.

[0003] Therefore, there is an urgent need for a simple and reasonably designed composite anti-derailment roller device. The roller is clamped on the rail so that the roller and the rail can adapt to the rail's deviation synchronously. The roller and the lower limit rotating body simultaneously fit against the bottom of the rail tread. This not only allows the roller to roll along the rail tread but also limits the roller to prevent it from derailing, thereby improving the safety of the roller traveling along the rail. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a composite anti-derailment roller device that addresses the shortcomings of the prior art. The device has a simple structure and reasonable design. The roller is clamped on the rail so that the roller and the rail can synchronously adapt to the rail's offset. The roller and the lower limit rotating body simultaneously fit against the bottom of the rail tread. This not only allows the roller to roll along the rail tread but also limits the roller to prevent it from derailing, thereby improving the safety of the roller traveling along the rail.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a composite anti-derailment roller device, characterized in that: it includes a roller disposed on a steel rail, an anti-derailment structure disposed on the roller, and a cleaning structure disposed on the anti-derailment structure;

[0006] The roller includes an axle and two roller treads integrally formed with the axle and sleeved at both ends of the axle. The roller treads can roll along the rail tread.

[0007] The anti-derailment structure includes a left wheel plate, a permanent magnet block disposed on the left wheel plate, a right wheel plate, an electric push rod disposed on the right wheel plate, an electromagnet disposed on the telescopic end of the electric push rod, and a lower limit rotating body disposed on the lower part of the left wheel plate and the right wheel plate.

[0008] The cleaning structure is located between the left and right wheel plates and is positioned below the front side of the roller, fitting against the rail tread.

[0009] The above-mentioned composite anti-derailment roller device is characterized in that: the left wheel plate and the right wheel plate are rotatably sleeved on the wheel axle by ball bearings, the left wheel plate is in close contact with the left side of the rail tread, and the right wheel plate is in close contact with the right side of the rail tread;

[0010] The left end of the axle protrudes through the left wheel plate, and the right end of the axle protrudes through the right wheel plate.

[0011] The above-mentioned composite anti-derailment roller device is characterized in that: the bottom of the left wheel plate and the right wheel plate extends below the bottom of the tread of the rail, the lower limit rotating body is a bolt roller bearing, and the two bolt roller bearings are symmetrically arranged.

[0012] The aforementioned composite anti-derailment roller device is characterized in that: the bolt shaft of the bolt roller bearing is installed on the left and right wheel plates, and the outer ring of the bolt roller bearing is in contact with the bottom of the tread of the rail.

[0013] The aforementioned composite anti-derailment roller device is characterized in that: the cleaning structure includes elastic connectors installed in the left and right wheel plates and a brush roller disposed between the two elastic connectors, the brush roller being located below the front side of the roller and conforming to the rail tread.

[0014] The above-mentioned composite anti-derailment roller device is characterized in that: the lower side of the left wheel plate and the right wheel plate is provided with an inclined mounting groove for the installation of the elastic connecting member, and each of the two elastic connecting members includes a base plate disposed at the bottom of the mounting groove, a connecting rod connected to the base plate and for the two ends of the brush roller to be sleeved, and a spring sleeved on the connecting rod, wherein the spring is located between the end of the brush roller and the base plate.

[0015] This utility model has the following advantages compared with the prior art:

[0016] 1. This utility model has a simple structure and compact size. It improves safety through the anti-derailment structure and improves adaptability to the construction environment through the cleaning structure.

[0017] 2. The present invention is provided with a left wheel plate and a right wheel plate. On the one hand, the left wheel plate is attached to the left side of the rail tread and the right wheel plate is attached to the right side of the rail tread, thereby limiting the outer side of the roller tread. On the other hand, it is for the layout of the cleaning structure.

[0031] like Figures 1 to 3 As shown, this utility model includes a roller 2 disposed on a rail 1, an anti-derailment structure disposed on the roller 2, and a cleaning structure disposed on the anti-derailment structure;

[0032] The roller 2 includes a wheel axle 2-1 and two roller tread bodies 2-2 integrally formed with the wheel axle 2-1 and sleeved at both ends of the wheel axle 2-1. The roller tread bodies 2-2 can roll along the tread of the rail 1.

[0033] The anti-derailment structure includes a left wheel plate 4, a permanent magnet block 6 disposed on the left wheel plate 4, a right wheel plate 5, an electric push rod 7 disposed on the right wheel plate 5, an electromagnet 8 disposed on the telescopic end of the electric push rod 7, and a lower limit rotating body disposed at the lower part of the left wheel plate 4 and the right wheel plate 5.

[0034] The cleaning structure is located between the left wheel plate 4 and the right wheel plate 5 and is positioned below the front side of the roller 2, fitting against the tread of the rail 1.

[0035] In this embodiment, the left wheel plate 4 and the right wheel plate 5 are both rotatably mounted on the wheel axle 2-1 by ball bearings. The left wheel plate 4 is in close contact with the left side of the rail 1 tread surface, and the right wheel plate 5 is in close contact with the right side of the rail 1 tread surface.

[0036] The left end of the axle 2-1 extends through the left wheel plate 4, and the right end of the axle 2-1 extends through the right wheel plate 5.

[0037] In this embodiment, the bottom of the left wheel plate 4 and the right wheel plate 5 extends below the bottom of the tread of the rail 1, and the lower limit rotating body is a bolt roller bearing 11, with the two bolt roller bearings 11 arranged symmetrically.

[0038] In this embodiment, the bolt shaft 10 of the bolt roller bearing 11 is installed on the left wheel plate 4 and the right wheel plate 5, and the outer ring of the bolt roller bearing 11 is in contact with the bottom of the tread of the rail 1.

[0039] In this embodiment, the cleaning structure includes elastic connectors installed in the left wheel plate 4 and the right wheel plate 5 and a brush roller 9 disposed between the two elastic connectors. The brush roller 9 is located below the front side of the roller and fits against the tread of the rail 1.

[0040] In this embodiment, the lower sides of the left wheel plate 4 and the right wheel plate 5 are provided with inclined mounting grooves 9-4 for the installation of the elastic connectors. Both elastic connectors include a base plate 9-1 disposed at the bottom of the mounting groove 9-4, a connecting rod 9-2 connected to the base plate 9-1 and sleeved at both ends of the brush roller 9, and a spring 9-3 sleeved on the connecting rod 9-2. The spring 9-3 is located between the end of the brush roller 9 and the base plate 9-1.

[0041] In this embodiment, in actual use, the left end of the axle 2-1 protrudes through the left wheel plate 4, and the right end of the axle 2-1 protrudes through the right wheel plate 5, so that the composite anti-derailment roller device can be installed on the wheel frame and then installed on the slope protection concrete lining machine.

[0042] In this embodiment, in actual use, multiple composite anti-derailment roller devices are used in combination to meet the load-bearing requirements of different locations.

[0043] In this embodiment, after actual installation, the extended end of the wheel axle 2-1 is connected to the drive motor, and the drive motor drives the two roller treads 2-2 to roll against the tread of the rail 1 through the wheel axle 2-1.

[0044] In this embodiment, in actual use, the left wheel plate 4 and the right wheel plate 5 are both rotatably mounted on the wheel axle 2-1 via ball bearings, so that when the roller rolls, the left wheel plate 4 and the right wheel plate 5 are limited to the outer side and do not rotate with the roller, thereby accommodating the installation of the electromagnet 8, the permanent magnet block 6, and the brush roller 9.

[0045] In this embodiment, in actual use, the brush roller 9 can be a steel wire brush roller or any other material that meets the requirements.

[0046] In this embodiment, in actual use, the brush roller 9 is provided with a central shaft inside.

[0047] In this embodiment, during actual use, the end of the central shaft extending out of the brush roller 9 extends into the mounting groove 9-4. The end of the central shaft is provided with a mounting hole. One end of the connecting rod 9-2 is connected to the base plate 9-1, and the other end of the connecting rod 9-2 passes through the mounting hole and is bolted. The bolt is located inside the mounting hole, thereby realizing the connection between the two ends of the connecting rod 9-2 and the brush roller 9.

[0048] In this embodiment, during actual use, the two ends of the brush roller 9 are sleeved on the connecting rod 9-2, so that the brush roller 9 is installed between the left wheel plate 4 and the right wheel plate 5. When the roller tread body 2-2 rolls along the tread of the rail 1, the brush roller 9 located in front of the roller moves with the roller. In this way, during the process of moving along the tread of the rail 1, the brush roller 9 contacts the tread of the rail 1, thereby grinding and cleaning the mud on the tread of the rail 1.

[0049] Furthermore, a spring 9-3 is provided between the end of the brush roller 9 and the base plate 9-1 so that if the brush roller 9 encounters an imbalance during its movement along the tread of the rail 1, the spring 9-3 can adjust the brush roller 9 to adapt, thus avoiding damage from hard-connected collisions.

[0050] In this embodiment, when selecting spring 9-3 for actual use, spring 9-3 should have a higher stiffness so that spring 9-3 is in a slightly compressed state. This ensures that spring 9-3 supports and ensures that the brush roller 9 and the tread surface of the rail 1 make contact for grinding and cleaning. At the same time, the contact between the brush roller 9 and the tread surface of the rail 1 also ensures the stability of the left wheel plate 4 and the right wheel plate 5. Only if the external force on one end is greater than the supporting force of the spring can the brush roller 9 be pushed to squeeze the spring 9-3 to continue to contract. Secondly, the brush roller 9 has its own weight passing through the contact with the tread surface of the rail 1, which also ensures the stability of the left wheel plate 4 and the right wheel plate 5.

[0051] In this embodiment, in actual use, the electric push rod 7 and the electromagnet 8 are powered by conventional methods in the art, as long as the power supply requirements are met and the rolling of the roller is not affected.

[0052] In this embodiment, in actual use, the lower limit rotating body can also be a rotating wheel, a rotating cylinder, etc., as long as the requirement of fitting and rotating is met.

[0053] In this embodiment, during actual use, when the left wheel plate 4 is in close contact with the left side of the rail 1 tread surface and the right wheel plate 5 is in close contact with the right side of the rail 1 tread surface, the left wheel plate 4 and the right wheel plate 5 are in contact with the outer side of the roller tread body 2-2, but this does not affect the rotation of the roller tread body 2-2 with the wheel axle 2-1.

[0054] In specific use, when the roller rolls against the tread of the steel rail 1, the electric push rod 7 and the electromagnet 8 are powered, the electric push rod 7 extends, and the extension of the electric push rod 7 pushes the electromagnet 8 close to the permanent magnet block 6. The electromagnet 8 and the permanent magnet block 6 have different magnetic properties until the electromagnet 8 and the permanent magnet block 6 attract each other.

[0055] With the electromagnet 8 and the permanent magnet 6 attracting each other, the left wheel plate 4 is attached to the left side of the rail tread surface and the right wheel plate 5 is attached to the right side of the rail tread surface. The left wheel plate 4 and the right wheel plate 5 clamp the rail 1, and the left wheel plate 4 and the right wheel plate 5 are in a stable state, so that the roller and the rail 1 are synchronized and adapt to the deviation of the rail 1. The outer ring of the bolt roller bearing 11 is attached to the bottom of the rail tread surface, which can not only adapt to the roller rolling on the rail tread surface, but also limit the roller and prevent the roller from derailing, thereby improving the safety of the roller traveling along the rail.

[0056] In summary, this utility model has a simple structure and reasonable design. The roller is clamped on the rail so that the roller and the rail can adapt to the rail's offset synchronously. Simultaneously, the lower limit rotating body fits against the bottom of the rail tread. This not only allows the roller to roll along the rail tread but also limits the roller to prevent it from derailing, thereby improving the safety of the roller traveling along the rail.

[0057] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
