Description

Technical Field

[0001] The present invention relates to the technical field of traffic construction equipment, and particularly relates to an auxiliary equipment for rail transit engineering construction. Background Art

[0002] With the continuous development of technology, the construction of urban buildings is also gradually improving. The development and construction of cities require better transportation to enable better transportation between cities through stable traffic. The most practical form of transportation is rail transit. Trains using pipeline transportation have designated starts and stops, which saves more time. However, rail transit requires the construction of designated traffic tracks. When maintaining and constructing the tracks, ballast needs to be laid. Track ballast is the crushed stone used in the railway transportation system to support the track sleepers and is a common track bed structure. Its function is to evenly transmit the pressure transmitted by the sleepers to the roadbed, drain rainwater in the track, prevent the sleepers from moving the rails, and relieve the impact of the wheels on the rails, so that the track has sufficient elasticity.

[0003] Generally, when laying track ballast, the stones of the track ballast have some finer crushed stones, and it is necessary to screen them in advance to ensure the stable laying of the ballast. The advance screening will increase the operation process. At the same time, when the track ballast is sprinkled out for laying, there will be a certain amount of dust, which affects the difficulty of leveling the track ballast. Summary of the Invention

[0012] In at least some embodiments, blanking boxes are provided at both ends of the bearing cylinder of the blanking assembly. The bearing cylinder is installed on the main frame assembly at the end of the filtering assembly through the blanking boxes. The bearing cylinder is set as a cover structure. The bottom of the bearing cylinder is set as an inverted triangular funnel structure.

[0013] In at least some embodiments, vertical guide plates are provided in the funnel part of the bearing cylinder. A shielding plate is hinged and installed at the outer end of the guide plate of the bearing cylinder.

[0014] The present invention provides an auxiliary device for rail transit engineering construction, having the following beneficial effects:

[0015] In the present invention, first of all, at the right side position of the main frame assembly, it is convenient to externally connect and expand devices for use. The bearing assembly of the main frame assembly is configured to stably bear ballast stones. A shielding assembly is installed on the top of the bearing assembly. The overall shielding assembly is relatively thin, allowing the ballast stones to be poured into the bearing assembly from the shielding assembly, and at the same time enabling the shielding assembly to assist in shielding the inside of the bearing assembly to avoid the problem of dust exposure. An adjusting assembly is installed on the main frame assembly at the bottom of the bearing assembly. A filtering assembly is swingably installed on the adjusting assembly. A spring is installed between the end position of the filtering assembly and the end of the adjusting assembly. At the same time, when the vibration motor provided at the end of the filtering assembly operates, when the ballast stones pass through the filtering assembly, the ballast stones can be better filtered through the shaking of the filtering assembly, reducing the generation of dust during subsequent discharging. The filtering assembly at the bottom of the adjusting assembly can discharge smaller dust materials, and the filtering assembly will discharge the ballast stones into the feeding assembly. A dust reduction assembly is installed on the top of the feeding assembly. When the ballast stones are close to entering the feeding assembly, the dust reduction assembly can spray mist, enabling the dust reduction assembly to reduce the dust of the passing ballast stones and preventing the problem of dust generated by the laid ballast stones. The bottom of the feeding assembly is set to be a structure close to the ground, enabling the ballast stones to be discharged closer to the ground through the feeding assembly and also reducing the dust caused by the ballast stones.

[0016] In addition, the bearing groove is directly set as an inverted trapezoidal structure, making it convenient to release the ballast stones through the trapezoidal bearing groove after the bearing groove internally bears the ballast stones. The side baffle rods at the upper end of the outer wall of the bearing groove can enable the bearing groove to be stably installed on the main frame assembly through the side baffle rods. The bottom of the bearing groove is set as a hollow structure, and a dispersion plate is arranged in the hollow part of the bearing groove, enabling the ballast stones in the bearing groove to be dispersed and fall through the dispersion plate. The top of the dispersion plate is vertically arc-shaped, achieving a uniform dispersion effect of the ballast stones in the bearing groove. First of all, the shielding layer is set as a thin sheet elastic structure, and a feeding groove is arranged above the shielding layer. The feeding groove is arranged in a fishbone shape. After the shielding layer is fixed on the top of the bearing assembly, the ballast stones can be put into the bearing assembly through the shielding assembly to break it. The feeding groove of the shielding layer can stably put the ballast stones, and the elastic shielding layer can quickly retract, enabling the shielding assembly to shield the dust when pouring the ballast stones into the bearing assembly.

[0017] In addition, the carrier frame is first set to be connected to the carrier filtration component for use. The filtration component needs to be adjusted to a certain slope during filtration. Therefore, the position of the main frame component at the outer end of the filtration component is hinged to install the carrier frame. The adjustment block at the end of the carrier frame slides on the main frame component. After adjusting the adjustment block, the angle adjustment of the end of the carrier frame can be achieved. The end of the carrier frame is connected to a bottom support plate, and the spring of the bottom support plate can directly contact the end of the filtration component. When the filtration component is screening and filtering, the filtration component can be quickly reset and buffered through the spring. The ballast stones will fall from the bottom of the carrier component onto the filter plate. The front and rear positions of the filter plate are blocked, which can keep the ballast stones stable on the filter plate and prevent the ballast stones from leaking from the filter plate. The filter plate is vertically a grid structure. When the end of the filter plate vibrates, the filter plate can filter the ballast stones through the grid structure, achieving the filtration and screening of some smaller ballast stones, and making the subsequent laying of the ballast stones more stable.

[0018] In addition, the carrier cylinder is first set to be a cover structure. When the carrier cylinder is at the end of the filtration component, the carrier cylinder can collect the ballast stones discharged by the filtration component. The funnel-shaped structure at the bottom of the carrier cylinder enables the bottom of the carrier cylinder to better collect and discharge the ballast stones. After the ballast stones are collected and discharged at the bottom of the carrier cylinder, the guide plate at the bottom of the carrier cylinder helps to evenly disperse the ballast stones. The baffle plate hinged at the outer end of the guide plate can open faster to discharge the ballast stones when the ballast stones are discharged too fast. When the filtration component screens the ballast stones, dust will inevitably appear in the ballast stones. Therefore, a dust reduction frame is installed at the top of the feeding component. After the dust reduction frame is connected to the water supply through an external pipe, the spray heads of the dust reduction frame generate water mist, which can reduce the dust of the ballast stones passing through the feeding component and also facilitate the subsequent use of the ballast stones for more convenient laying.

The reinforcing part between the extension frame 102 and the main frame body 101 can make the extension frame 102 and the main frame body 101 more stable. At the same time, when the external connection buckle 103 on the extension frame 102 is externally connected to other devices, the external connection buckle 103 plays a more stable role.

[0043] In the embodiments of the present disclosure, as Figure 1 Figure 6As shown, the bearing groove 201 of the bearing component 2 is integrally arranged in an inverted trapezoidal structure. At the same time, side retaining rods 202 are provided on the outer wall of the bearing groove 201. The bearing groove 201 is clamped on the main frame component 1 through the side retaining rods 202. The bearing groove 201 is directly arranged in an inverted trapezoidal structure, so that after the ballast stone is carried inside the bearing groove 201, it is convenient to be released through the trapezoidal bearing groove 201. The side retaining rods 202 at the upper end of the outer wall of the bearing groove 201 enable the bearing groove 201 to be stably installed on the main frame component 1 through the side retaining rods 202. The bottom of the bearing groove 201 is arranged in a hollow shape, and a dispersion plate 203 is provided in the hollow part at the bottom of the bearing groove 201. The top of the dispersion plate 203 is arranged in an arc shape. By arranging the bottom of the bearing groove 201 in a hollow structure and providing the dispersion plate 203 in the hollow part of the bearing groove 201, the ballast stone in the bearing groove 201 is dispersed and falls through the dispersion plate 203. The top of the dispersion plate 203 is vertically arranged in an arc shape, so as to achieve a uniform dispersion effect of the ballast stone in the bearing groove 201.

[0044] In the embodiment of the present disclosure, as Figure 6 shown, the shielding layer 301 of the shielding component 3 is fixed at the top position of the bearing component 2. The shielding layer 301 is arranged in a thin sheet elastic structure, and a feed groove 302 is provided on the shielding layer 301. The feed groove 302 is vertically arranged in a fishbone-like layout structure. First, the shielding layer 301 is arranged in a thin sheet elastic structure, and the feed groove 302 is provided above the shielding layer 301. The feed groove 302 is arranged in the shape of a fishbone, so that after the shielding layer 301 is fixed at the top of the bearing component 2, the ballast stone is put into the bearing component 2 through the shielding component 3. The feed groove 302 of the shielding layer 301 can stably put the ballast stone, and the elastic shielding layer 301 can quickly retract, so that the shielding component 3 can shield the dust when the ballast stone is poured into the bearing component 2.

[0045] In the embodiment of the present disclosure, as Figure 4 Figure 5As shown in the figure, the carrier 401 of the adjustment assembly 4 has a frame-like structure.

A horizontal bottom support plate 403 is connected to the end of the carrier 401, and a spring is installed on the bottom support plate 403. First, the carrier 401 is set to be connected to the load-bearing and filtering assembly 5. The filtering assembly 5 needs to be adjusted to a certain slope during filtering. Therefore, the position of the main frame assembly 1 at the outer end of the filtering assembly 5 is hingedly installed with the carrier 401. The regulating block 402 at the end of the carrier 401 slides on the main frame assembly 1, so as to realize the angle adjustment of the end of the carrier 401 after adjusting the regulating block 402. The end of the carrier 401 is connected with a bottom support plate 403, and the spring of the bottom support plate 403 can directly contact the end of the filtering assembly 5, enabling the filtering assembly 5 to quickly reset and buffer through the spring when screening and filtering.

[0046] In the embodiment of the present disclosure, as Figure 3 Figure 5 shown in the figure, shields are provided at the front and rear edge positions of the filter plate 501 of the filtering assembly 5. The left side of the filter plate 501 is swingably installed on the adjustment assembly 4. The filter plate 501 is set as a grid structure. A vibration motor 502 is provided at the bottom of the end of the filter plate 501. Ballast stones will fall from the bottom of the load-bearing assembly 2 onto the filter plate 501. The front and rear positions of the filter plate 501 are shielded, which can keep the ballast stones stable on the filter plate 501 and prevent the ballast stones from leaking from the filter plate 501. The filter plate 501 is vertically grid-shaped, enabling the filter plate 501 to filter the ballast stones through the grid structure when the end shakes, so as to realize the filtering and screening of some smaller ballast stones, and achieve the effect of making the subsequent laying of ballast stones more stable.

[0047] In the embodiment of the present disclosure, as Figure 5 shown in the figure, the bottom material rack 601 of the auxiliary assembly 6 is installed at the bottom of the adjustment assembly 4 on the main frame assembly 1. An outer discharge port 602 is installed at the bottom of the bottom material rack 601. The outer discharge port 602 is set as a structure inclined towards the left. A conveyor belt 603 is provided at the left side position of the bottom material rack 601. First, the bottom material rack 601 is set to be installed at the bottom of the adjustment assembly 4 on the main frame assembly 1, so that the bottom material rack 601 can better approach the bottom of the filtering assembly 5 on the adjustment assembly 4, enabling the filtering assembly 5 to collect the screened ballast stone debris. The outer discharge port 602 of the bottom material rack 601 drives the ballast stone debris to be conveyed towards the left, and the conveyor belt 603 at the left side position of the bottom material rack 601 facilitates the discharge of the ballast stone debris.

[0048] In the embodiment of the present disclosure, as Figure 7As shown in the figure, blanking boxes 702 are provided at both ends of the loading cylinder 701 of the blanking assembly 7. The loading cylinder 701 is installed on the main frame assembly 1 at the end of the filtering assembly 5 through the blanking boxes 702. The loading cylinder 701 is set as a cover structure, and the bottom of the loading cylinder 701 is set as an inverted triangular funnel structure. First, the loading cylinder 701 is set as a cover structure, so that when the loading cylinder 701 is at the end of the filtering assembly 5, the loading cylinder 701 can collect the ballast stones discharged by the filtering assembly 5. The funnel-shaped structure at the bottom of the loading cylinder 701 enables the bottom of the loading cylinder 701 to better collect and discharge the ballast stones.

[0049] In the embodiments of the present disclosure, as Figure 8 shown, a vertical guide plate 704 is provided at the funnel part of the loading cylinder 701. A baffle plate 703 is hingedly installed at the outer end of the guide plate 704 of the loading cylinder 701. After the ballast stones are collected and discharged at the bottom of the loading cylinder 701, the guide plate 704 at the bottom of the loading cylinder 701 assists in evenly dispersing the ballast stones. The baffle plate 703 hingedly installed at the outer end of the guide plate 704 can enable the baffle plate 703 to open and discharge the ballast stones faster when the ballast stones are discharged too fast.

[0050] The working principle of this embodiment: Before use, first adjust the position of the blanking assembly 7. Adjust the position of the bottom of the hair dye blanking assembly 7 close to the ground to a suitable height. Then loosen the adjusting block 402 at the end position of the adjusting assembly 4, adjust the height position of the adjusting block 402 and fix it. At the same time, observe whether the dust reduction assembly 8 of the blanking assembly 7 is stably connected;

[0051] During use, directly pour the ballast stones from the position of the shielding assembly 3 of the loading assembly 2. The loading assembly 2 will evenly disperse the ballast stones to the bottom position. At this time, the ballast stones fall onto the filtering assembly 5 of the adjusting assembly 4. At the same time, the vibration motor 502 at the end of the filtering assembly 5 will run, making the entire filtering assembly 5 form a vibrating state, so as to realize the vibration of the filtering assembly 5 on the adjusting assembly 4 to filter the ballast stones passing through the filtering assembly 5. The falling debris will be discharged through the filtering assembly 5, and the filtering assembly 5 will directly discharge the ballast stones to the blanking assembly 7. At this time, the dust reduction assembly 8 of the blanking assembly 7 will spray mist to reduce the dust generated by the ballast stones. Then the ballast stones will fall into the blanking assembly 7. The bottom of the blanking assembly 7 is closer to the ground, so as to avoid generating smoke and dust when the ballast stones are discharged.
