Description

Technical Field

[0001] This utility model relates to the field of railway signal equipment construction technology, specifically a high-mast signal traction assembly device. Background Technology

[0002] High-mast signals are a key type of color light signal in railway signaling systems. With their technical characteristics of long display distance and clear observation position, they transmit precise train operation instructions through combinations of different colored lights such as red, yellow, green, blue, and off-white. They are widely used in core scenarios such as entering stations, leaving main lines, and shunting on lead lines, and are important facilities to ensure the safe and orderly operation of trains.

[0003] The structure of a high-mast signal mainly includes the mast, crossarm assembly, and signal display mechanism. The mast, as the core load-bearing structure, is mostly made of reinforced concrete or steel, with common heights of 8.5m, 10m, and 12m, and a weight of 500-1000kg. Its bottom needs to be buried deep in the underground foundation pit to ensure overall stability. The crossarm assembly is located on the upper part of the mast and is used not only to fix the signal display mechanism but also to control the angle of the signal display mechanism to ensure that the light signal is facing the direction of train travel. The signal display mechanism is the functional component that emits various color signals, which directly determines the effective transmission of train operation instructions.

[0004] Due to their height and weight, the erection of high-mast signaling systems presents significant challenges. At the installation site, the dense distribution of overhead contact lines severely restricts the use of common lifting equipment such as truck cranes. This is mainly reflected in two aspects: firstly, the rotation range of the booms of large equipment like truck cranes is prone to interfering with the overhead contact line, making it difficult to maintain a safe distance from energized parts; secondly, in areas with dense track networks or complex terrain such as embankments and cuts within the station, the outriggers of large lifting equipment are difficult to securely erect, posing a risk of overturning.

[0005] Therefore, existing technologies often employ manual lifting for installation: first, a fixed pulley is installed on the already installed high-mast signal; one end of the steel strand is looped around the fixed pulley and connected to the high-mast signal to be installed; then, the other end of the steel strand is manually pulled to lift it up. While this method can avoid spatial conflicts with the overhead contact line to some extent, it has significant inherent drawbacks: an 8.5-meter mast requires at least 12 people to work together, and masts of 10 meters or more require more than 15 people, resulting in extremely high labor intensity and low installation efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-mast signal traction and erection device, which reduces the labor intensity when traction of high-mast signals and improves installation efficiency.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a high-mast signal traction assembly device, including a mounting frame and a support;

[0008] The mounting frame is rotatably equipped with a first wheel shaft and a second wheel shaft. A driving wheel is fixedly mounted on the first wheel shaft, and two driven wheels are fixedly mounted on the second wheel shaft. The driving wheel meshes with one of the driven wheels. Steel strand is wound on the part of the second wheel shaft located between the two driven wheels.

[0009] The bracket includes a mounting plate and multiple legs that are rotatably mounted at the bottom of the mounting plate. A fixed pulley is fixedly mounted on the top of the mounting plate, and the steel strand passes over the fixed pulley and is fixedly connected to the high-column signal.

[0010] As a further optimization of the high-mast signal traction assembly device of the utility model: a third wheel axle is rotatably arranged on the mounting frame, the third wheel axle is located between the first wheel axle and the second wheel axle, and two transmission wheels that mesh with the driven wheel are fixedly arranged on the third wheel axle, and one of the transmission wheels meshes with the driving wheel.

[0011] As a further optimization of the high-mast signal traction assembly device of the utility model: the first wheel axle, the second wheel axle and the third wheel axle are all connected to the mounting frame through mounting seats. The mounting seat includes a liner fixedly connected to the mounting frame and a mounting block fixedly disposed on the liner. The first wheel axle, the second wheel axle and the third wheel axle are all rotatably connected to the mounting block.

[0012] As a further optimization of the high-mast signal traction assembly device of the utility model: both ends of the first wheel axle are fixedly connected to the side of the mounting frame.

[0013] As a further optimization of the high-mast signal traction assembly device of the utility model: the part of the first wheel axle that passes through the mounting block is fixedly connected to a connecting cylinder, and the outer wall of the connecting cylinder is connected to the hand crank through a lever.

[0014] As a further optimization of the high-mast signal traction assembly device of the utility model: several hooks are fixedly installed on the mounting frame, and two symmetrical lifting lugs are fixedly installed on the top of the mounting frame.

[0015] As a further optimization of the high-mast signal traction assembly device of the utility model: the adjacent outriggers are connected by a connector, which includes a connecting rod and two clamping plates. Both ends of the connecting rod are fixedly connected to the connecting plates, and the clamping plates are fixedly connected to the connecting plates by the first bolt after being clamped onto the outriggers.

[0016] As a further optimization of the high-mast signal traction assembly device of the utility model: the clamping plate includes a first part and two second parts. The first part is U-shaped, and the inner sidewall of the first part forms a receiving space for accommodating the support leg. The second parts are fixedly connected to the two ends of the first part respectively. When the support leg is located in the receiving space, the second part is connected to the connecting plate by the first bolt.

[0017] As a further optimization of the high-mast signal traction assembly device of the utility model: both the mounting frame and the bottom of the support leg are provided with pads.

[0018] As a further optimization of the high-mast signal traction assembly device of the utility model: the fixed pulley is fixedly connected to the mounting plate through a support rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

Only a few workers are needed to assist and support the high-mast signal from its sides to prevent it from tipping over. This invention reduces the labor intensity of installing high-mast signales and improves installation efficiency. Attached Figure Description

[0029] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the model of the driving wheel 2, the driven wheel 4 and the transmission wheel 3, the cooperation between the driving wheel 2, the driven wheel 4 and the transmission wheel 3, the model of the fixed pulley 17, the cooperation between the steel strand 12 and the fixed pulley 17, etc.

[0030] Example 1

[0031] like Figures 1 to 6 As shown, a high-mast signal traction assembly device includes a mounting frame 1 and a support. A first wheel axle 6 and a second wheel axle 7 are rotatably mounted on the mounting frame 1. A drive wheel 2 is fixedly mounted on the first wheel axle 6, and two driven wheels 4 are fixedly mounted on the second wheel axle 7. The drive wheel 2 and one of the driven wheels 4 are meshed. A steel strand 12 is wound on the portion of the second wheel axle 7 between the two driven wheels 4. The support includes a mounting plate 15 and a plurality of legs 13 rotatably mounted on the bottom of the mounting plate 15. A fixed pulley 17 is fixedly mounted on the top of the mounting plate 15. The steel strand 12 passes over the fixed pulley 17 and is fixedly connected to the high-mast signal 28.

[0032] When it is necessary to install the high-mast signal 28, a bracket is placed at a preset position between the high-mast signal 28 and the mounting frame 1. The output end of the steel strand 12 wound on the second wheel shaft 7 is passed around the fixed pulley 17 and connected to the high-mast signal 28. The operator drives the drive wheel 2 to rotate. During the rotation of the drive wheel 2, its teeth mesh with the teeth of one of the driven wheels 4, thereby driving the driven wheel 4 to rotate synchronously.

[0033] Since the driven wheel 4 and the second wheel shaft 7 are fixedly connected, such as by interference fit or key connection, when the driven wheel 4 rotates, the second wheel shaft 7 rotates together with the driven wheel 4. During this process, the steel strand 12 wound on the second wheel shaft 7 retracts as the second wheel shaft 7 rotates. During the retraction of the steel strand 12, the high-post signal 28 is gradually pulled up under the traction force of the steel strand 12.

[0034] When the high-mast signal 28 is pulled to a vertical position, the operator controls the drive wheel 2 to stop rotating. After the drive wheel 2 stops rotating, the driven wheel 4 meshing with it loses its power source and stops rotating. The second wheel shaft 7 stops rotating synchronously, so that the steel strand 12 no longer continues to retract, and the high-mast signal 28 is kept in a vertical position.

[0035] Furthermore, two driven wheels 4 are spaced apart along the axial direction of the second wheel shaft 7, forming an installation space between them to accommodate the steel strand 12. The steel strand 12 is wound around the outer circumference of the second wheel shaft 7 in a predetermined winding manner, and the winding area of ​​the steel strand 12 is completely located within the aforementioned installation space. Since the diameters of the two driven wheels 4 are both larger than the diameter of the second wheel shaft 7, and the edges of the driven wheels 4 extend beyond the winding range of the steel strand 12, the two driven wheels 4 can radially limit the steel strand 12 during the rotation of the steel strand 12 driven by the second wheel shaft 7, effectively preventing the steel strand 12 from shifting in the axial direction or detaching from the predetermined winding position of the second wheel shaft 7.

[0036] In this embodiment, four support legs 13 are provided, and the four support legs 13 are evenly distributed along the circumference of the mounting plate 15; wherein, the support legs 13 are hinged to the bottom of the mounting plate 15. The operator can adjust the rotation angle of each support leg 13 to ensure that the entire bracket is in a stable horizontal support state.

[0037] To further improve the anti-tipping performance of the support under stress, counterweights need to be placed around each leg 13 of the support during the process of the steel strand 12 pulling the high-mast signal 28. The counterweights can be in the form of burlap sacks filled with soil. In practice, multiple burlap sacks filled with soil are pressed onto the ground around each leg 13 and the upper surface of each leg 13. The weight of the counterweights increases the friction between the leg 13 and the ground and lowers the overall center of gravity of the support, thereby ensuring that the support remains stable when subjected to the traction reaction force of the high-mast signal 28.

[0038] This invention achieves traction of the high-mast signal 28 through the cooperation of the driving wheel 2, driven wheel 4, steel strand 12, and fixed pulley 17 on the bracket. This process eliminates the need for a large number of operators to lift it; simply driving the driving wheel 2 to rotate retracts the steel strand 12 connected to the high-mast signal 28. Only a few workers are needed to provide support around the high-mast signal 28 to prevent it from tipping over. This invention reduces the labor intensity of installing the high-mast signal 28 and improves installation efficiency.

[0039] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0040] Example 2

[0041] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figures 2 to 4 As shown, a third wheel shaft 8 is rotatably mounted on the mounting bracket 1. The third wheel shaft 8 is located between the first wheel shaft 6 and the second wheel shaft 7. Two transmission wheels 3 that mesh with the driven wheel 4 are fixedly mounted on the third wheel shaft 8, and one of the transmission wheels 3 meshes with the driving wheel 2.

[0042] During the rotation of the driving wheel 2, its teeth mesh with the teeth of one of the transmission wheels 3, thereby driving the transmission wheel 3 to rotate synchronously. The transmission wheel 3 and the third shaft 8 are fixedly connected, such as by a key or interference fit. When one of the transmission wheels 3 rotates under the drive of the driving wheel 2, the third shaft 8 rotates accordingly. During this process, since the other transmission wheel 3 on the third shaft 8 is fixedly connected to the third shaft 8 in the same way, it rotates synchronously with the third shaft 8. Through the synergistic effect of the two transmission wheels 3 and the third shaft 8, the instantaneous impact force transmitted from the driving wheel 2 to the driven wheel 4 can be effectively dispersed, reducing the stress load when the driving wheel 2 and the driven wheel 4 mesh, thereby extending the overall service life of the transmission system.

[0043] The drive wheel 3 and the driven wheel 4 mesh with each other. During the transmission process of the drive wheel 3, the driven wheel 4 rotates together under the drive of the drive wheel 3 through the meshing action between the gear teeth. In this embodiment, the ratio of the speed of the drive wheel 2 to the speed of the driven wheel 4 is 8:1, which ensures that the steel strand 12 pulls the high-mast signal 28 more smoothly and reduces the risk of the high-mast signal 28 shaking.

[0044] Example 3

[0045] This embodiment is an improvement on embodiment 2. Its main structure is the same as that of embodiment 2, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 As shown, to facilitate the connection between the first wheel axle 6, the second wheel axle 7, and the third wheel axle 8 and the mounting frame 1, the first wheel axle 6, the second wheel axle 7, and the third wheel axle 8 are all connected to the mounting frame 1 via mounting seats. The mounting seat includes a liner 10 fixedly connected to the mounting frame 1 and a mounting block 11 fixedly mounted on the liner 10. The first wheel axle 6, the second wheel axle 7, and the third wheel axle 8 are all rotatably connected to the mounting block 11. The liner 10 is fixedly connected to the mounting frame 1 via two second bolts. The mounting block 11 is located between the two second bolts, and the first wheel axle 6, the second wheel axle 7, and the third wheel axle 8 are all rotatably connected to the mounting block 11 via bearings.

[0046] Example 4

[0047] This embodiment is an improvement on embodiment 3. Its main structure is the same as that of embodiment 3, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 3 and Figure 5 As shown, to facilitate the operator's driving of the drive wheel 2, both ends of the first wheel axle 6 extend to the sides of the mounting bracket 1 and are fixedly connected to hand cranks 26. The operator can directly rotate the hand cranks 26 to drive the first wheel axle 6 to rotate. Alternatively, both ends of the first wheel axle 6 can be extended to the rear side of the mounting bracket 1, with hand cranks 26 fixedly connected to both ends. Two operators can then rotate the hand cranks 26 simultaneously, saving effort for each person.

[0048] The operator can drive the first wheel axle 6 to rotate by directly turning the hand crank 26. In practice, both ends of the first wheel axle 6 can be extended axially to the rear side of the mounting bracket 1, and the hand crank 26 is installed at both ends of the first wheel axle 6 by key connection and locking with nuts. Two operators can hold the hand crank 26 at the ends of the first wheel axle 6 and rotate it synchronously. By coordinating the operation with two people, the force required by a single operator is distributed, thus saving the strength of each operator. At the same time, the symmetrical arrangement of the hand cranks 26 at both ends can make the force on the first wheel axle 6 more even, reducing the risk of wheel axle bending deformation or transmission jamming caused by unilateral force, and ensuring more stable traction of the high-mast signal 28.

[0049] A connecting cylinder 24 is fixedly connected to the portion of the first wheel axle 6 that passes through the mounting block 11. The outer wall of the connecting cylinder 24 is connected to the hand crank 26 via a lever 25. The connecting cylinder 24 is fixedly connected to the end of the first wheel axle 6, such as by welding or interference fit. The connecting cylinder 24 and the hand crank 26 are connected via the lever 25, and the axial direction of the hand crank 26 is parallel to the axial direction of the first wheel axle 6. When the operator holds the end of the hand crank 26 to rotate it, compared to the method where the hand crank 26 is directly connected to the first wheel axle 6, the lever 25 extends the operator's lever arm, reducing the force required by the operator; in addition, this arrangement saves space.

[0050] Example 5

[0051] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 3 As shown, in order to achieve a stable fixation of the mounting frame 1 and prevent it from shifting due to force during the traction process of the high-mast signal 28, a number of hooks 9 are fixedly installed on the mounting frame 1. The number of hooks 9 is set to 5 to 6. Through multi-directional force balance, the mounting frame 1 is ensured to remain stable when subjected to the traction force of the steel strand 12.

[0052] Meanwhile, to facilitate the handling and repositioning of the mounting frame 1, two symmetrical lifting lugs 5 are fixedly installed on the top of the mounting frame 1. The lifting lugs 5 are connected to the top frame of the mounting frame 1 by welding or other methods.

[0053] Example 6

[0054] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 6 and Figure 7 As shown, to further enhance the stability of the outriggers 13 and prevent lateral displacement during stress, adjacent outriggers 13 are connected by connectors 14. Connectors 14 include connecting rods 18 and two clamping plates 20. Connecting plates 19 are fixedly connected to both ends of the connecting rods 18, and the connecting plates 19 are welded to the ends of the connecting rods 18. After the clamping plates 20 are engaged with the outriggers 13, they are fixedly connected to the connecting plates 19 by the first bolt 21. At this point, the outriggers 13 can no longer rotate, and their position is fixed.

[0055] The card plate 20 includes a first part 22 and two second parts 23. The first part 22 is U-shaped, and the inner sidewall of the first part 22 forms a receiving space for accommodating the support leg 13. The second parts 23 are fixedly connected to the two ends of the first part 22 respectively. When the support leg 13 is located in the receiving space, the second part 23 is connected to the connecting plate 19 by the first bolt 21.

[0056] The outrigger 13 is adapted to the inner wall of the first part 22. When the outrigger 13 is located inside the receiving space, the second part 23 is attached to the connecting plate 19. The first bolt 21 passes through the second part 23 and the connecting plate 19 in sequence and is threadedly connected to the second part 23 and the connecting plate 19 in sequence.

[0057] Example 7

[0058] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 6 As shown, both the mounting frame 1 and the support leg 13 are provided with pads 27 at their bottoms. The pads 27 can ensure that the bottom of the mounting frame 1 and the bottom of the support leg 13 slip when they come into contact with the ground. The part of the pads 27 that comes into contact with the ground can be provided with anti-slip texture.

[0059] Example 8

[0060] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 6As shown, the fixed pulley 17 is fixedly connected to the mounting plate 15 via a support rod 16. The support rod 16 is vertically fixedly mounted on the mounting plate 15, the fixed pulley 17 is located at the top of the support rod 16, and the support rod 16 is fixedly connected to the bearing seat of the fixed pulley 17 to ensure that the fixed pulley 17 can rotate around its own axle.
