[0002] With the continuous improvement of industrial automation, the manufacturing process of precast track slabs is also constantly being improved and upgraded. In the production of precast track slabs, the automatic transfer and installation of conduits is one of the key processes. Initially, the handling and installation of conduits relied mainly on manual labor. However, with the development of automation technology, automated solutions based on conveyor belt transport and automatic clamping and installation have gradually emerged.

[0003] Currently, the main method for transporting conduits during the manufacturing process of precast track slabs is by conveyor belt transport. This involves placing the conduits on the conveyor belt and using clamping devices to position and hold them, thus achieving automated transport. This method can improve production efficiency and reduce the labor intensity of workers to some extent.

[0004] However, existing technologies are prone to positional shifts in the conduit during its transport on the conveyor belt, affecting the precise positioning of subsequent processes. At the same time, traditional clamping devices often fail to accurately position and clamp the conduit, resulting in insufficient installation accuracy and affecting the manufacturing quality of the precast track slabs.

[0040] With the continuous improvement of industrial automation, the manufacturing process of precast track slabs is also constantly being improved and upgraded. In the production of precast track slabs, the automatic transfer and installation of conduits is one of the key processes. Initially, the handling and installation of conduits relied mainly on manual labor. However, with the development of automation technology, automated solutions based on conveyor belt transport and automatic clamping and installation have gradually emerged.

[0041] Currently, the main method for transporting conduits during the manufacturing process of precast track slabs is by conveyor belt transport. This involves placing the conduits on the conveyor belt and using clamping devices to position and hold them, thus achieving automated transport. This method can improve production efficiency and reduce the labor intensity of workers to some extent.

[0042] The applicant's research found that existing technologies are prone to positional shifts in the conduit during its transmission on the conveyor belt, affecting the precise positioning of subsequent processes. At the same time, traditional clamping devices often fail to accurately position and clamp the conduit, resulting in insufficient installation accuracy and affecting the manufacturing quality of the precast track slabs.

[0043] This utility model proposes a cover for a conduit conveyor.

[0044] Please see Figures 1 to 3 In one embodiment of this utility model, the conduit conveying wire cover includes:

[0045] A cover body 100 is provided on top of a conveyor belt for placing and conveying conduits. The cover body 100 has a receiving cavity 110 with a bottom opening, and a material passage 120 is formed at the bottom of the cover body 100 along the extension direction of the conveyor belt, communicating with the receiving cavity 110. The top of the cover body 100 has a mounting hole communicating with the receiving cavity 110.

[0046] The sleeve clamping mechanism 200 is installed in the mounting hole and can be lowered to clamp the external conduit placed on the conveyor belt.

[0047] Specifically, the cover body 100 is installed on top of the conveyor belt, and provides a protective channel for the external conduit through the cooperation of the receiving cavity 110 and the material passage 120. When it is necessary to clamp the external conduit, the sleeve clamping mechanism 200 installed in the mounting hole can descend and accurately clamp the external conduit on the conveyor belt.

[0048] In this embodiment, by setting up a cover body 100 and a sleeve clamping mechanism 200, during use, the cover body 100, which is installed on the top of the conveyor belt used for conveying the conduit, is used to initially position the conduit. Then, the conduit clamping mechanism installed on the cover body 100 descends from the top of the cover body 100 into the receiving cavity 110 and clamps the conduit positioned in the receiving cavity 110, thereby achieving the function of accurately positioning and clamping the conduit. Thus, this utility model can achieve precise positioning and clamping of the conduit by utilizing the cooperation between the cover body 100 and the conduit clamping mechanism installed on the cover body 100 during use, thereby ensuring the stability of the conduit during subsequent transfer and installation, and thus ensuring the installation accuracy of the conduit and the manufacturing quality of the track plate.

[0049] In one embodiment, the sleeve clamping mechanism 200 includes:

[0050] Mounting base 210 is mounted in mounting hole, and through hole 220 is formed on mounting base 210;

[0051] Telescopic assembly 230 is mounted on mounting base 210 and can descend into receiving cavity 110 to clamp external conduit placed on conveyor belt.

[0052] Specifically, a mounting hole is formed at the bottom of the cover body 100, and the sleeve clamping mechanism 200 is fixedly connected to the mounting hole by the mounting base 210. A stable assembly relationship is formed between the mounting base 210 and the mounting hole, ensuring that the sleeve clamping mechanism 200 can be reliably installed on the cover body 100. The through hole 220 formed on the mounting base 210 provides a movement channel for the telescopic component 230, through which the telescopic component 230 can move up and down under the guidance of the mounting base 210.

[0053] In actual operation, the telescopic component 230 passes through the through hole 220 of the mounting base 210 and descends into the receiving cavity 110 inside the cover body 100. Since the receiving cavity 110 has an open bottom and communicates with the feed chute 120, the telescopic component 230 can contact the external conduit placed on the conveyor belt after descending. The telescopic component 230 clamps the external conduit using its clamping function, thereby achieving precise positioning and fixation of the external conduit.

[0054] In one embodiment, the telescopic component 230 includes:

[0055] The housing 231 is sealed to the mounting base 210, and a pushing cavity 232 is formed inside the housing 231, which communicates with the through hole 220; and,

[0056] The sleeve extraction component 233 is installed in the push cavity 232 and can descend along the push cavity 232 into the receiving cavity 110 to clamp the external cable placed on the conveyor belt.

[0057] Specifically, the push cavity 232 inside the housing 231 is connected to the through hole 220 of the mounting base 210, providing movement space for the sleeve extraction component 233. The sleeve extraction component 233 is installed inside the housing 231, and through the guiding effect of the push cavity 232 and the through hole 220, it can achieve stable descent.

[0058] In actual operation, the sleeve extraction component 233, under the limiting action of the outer shell 231 and the mounting base 210, descends along the movement channel formed by the pushing cavity 232 and the through hole 220 into the receiving cavity 110 of the cover body 100. Because the outer shell 231 and the mounting base 210 are sealed together, shaking of the sleeve extraction component 233 during movement is avoided, ensuring that it accurately reaches the predetermined position and achieves precise clamping of the external conduit.

[0059] In one embodiment, the cannula extraction member 233 includes:

[0060] A sliding rod 234, one end of which is located within the pushing cavity 232, and the other end passing through the through hole 220 and extending out of the pushing cavity 232, wherein the end of the sliding rod 234 located within the pushing cavity 232 forms a piston section that slides in cooperation with the inner wall of the pushing cavity 232; and,

[0061] Extraction sleeve 235 is installed at one end of sliding rod 234 extending out through hole 220.

[0062] Specifically, the piston section and the inner wall of the push chamber 232 are in a sliding fit to ensure that the sliding rod 234 can move stably. The other end of the sliding rod 234 passes through the through hole 220 of the mounting base 210 and extends into the receiving cavity 110. The extraction sleeve 235 is installed on the extended end for clamping the external cable.

[0063] During actual operation, the piston section reciprocates within the pushing chamber 232, causing the sliding rod 234 to move up and down. Due to the sliding fit between the piston section and the inner wall of the pushing chamber 232, the sliding rod 234 can move smoothly along a predetermined trajectory. After the sliding rod 234 passes through the through hole 220, the extraction sleeve 235 installed at its end can accurately reach the predetermined position to clamp the external conduit.

[0064] In one embodiment, the extraction sleeve 235 is threadedly engaged with one end of the sliding rod 234 that extends into the through hole 220.

[0065] Specifically, the extension end of the sliding rod 234 is formed with an external thread, and the inner hole of the extraction sleeve 235 is formed with an internal thread that matches the external thread. The reliable connection between the extraction sleeve 235 and the sliding rod 234 is achieved through the threaded engagement.

[0066] In actual assembly, the extraction sleeve 235 is installed on the extension end of the sliding rod 234 by rotating it with a thread. The threaded engagement structure ensures that the extraction sleeve 235 is firmly fixed to the sliding rod 234, preventing loosening or detachment during the clamping of the external conduit. Furthermore, when it is necessary to replace or maintain the extraction sleeve 235, it can be easily removed from the sliding rod 234 by rotating it in the opposite direction.

[0067] In one embodiment, the housing 231 includes:

[0068] The outer sleeve 236 has a bottom sealing fit with the mounting base 210, and a push cavity 232 is formed inside the outer sleeve 236. The sliding rod 234 is accommodated inside the outer sleeve 236.

[0069] Sealing seat 237, sealing seat 237 and outer sleeve 236 at the end away from mounting seat 210 are in sealing engagement; and,

[0070] Fastening bolt 238 passes through sealing seat 237 and is threaded into mounting seat 210.

[0071] Specifically, the push chamber 232 formed inside the outer sleeve 236 provides movement space for the sliding rod 234, and the piston section of the sliding rod 234 reciprocates within the push chamber 232. The sealing seat 237 is installed at the top of the outer sleeve 236, that is, the end away from the mounting seat 210, and forms a sealing fit with the outer sleeve 236 to close the upper opening of the push chamber 232.

[0072] During actual assembly, the sealing fit between the bottom of the outer sleeve 236 and the mounting base 210 ensures the sealing of the push cavity 232, preventing external impurities from entering and affecting the movement of the sliding rod 234. The sealing fit between the sealing seat 237 and the top of the outer sleeve 236 further enhances the sealing performance of the entire housing 231. The fastening bolt 238 passes through the sealing seat 237 and forms a threaded connection with the mounting base 210, fastening the outer sleeve 236, the sealing seat 237, and the mounting base 210 into a single, stable, and reliable integrated structure.

[0073] In one embodiment, the mounting base 210 has a first vent 242 and a first exhaust vent 241 that communicate with the pushing cavity, and the first exhaust vent 241 and the first vent 242 are spaced apart.

[0074] A groove 239 is formed on the side of the sealing seat 237 facing the pushing cavity 232, and a second air hole 243 and a second exhaust hole 244 communicating with the groove 239 are formed on the sealing seat 237.

[0075] Both the first air hole 242 and the second air hole 243 are connected to an external air source through pipelines. The external air source can blow gas into the air groove 239 through the second air hole 243 and the gas in the pushing cavity 232 is discharged from the first exhaust hole 241, so that the sliding rod 234 slides down along the pushing cavity 232 to extend out of the through hole 220 and clamp the wire tube placed on the conveyor belt. The external air source can also introduce gas into the pushing cavity 232 through the first air hole 242 and the gas in the air groove 239 is discharged from the second exhaust hole 244, so that the sliding rod 234 slides up along the pushing cavity to retract and be housed in the pushing cavity.

[0076] Specifically, the first air hole 242 and the first exhaust hole 241 are spaced apart on the mounting base 210 and maintain communication with the pushing cavity. The air groove 239 on the sealing base 237 is arranged facing the pushing cavity 232, and the second air hole 243 and the second exhaust hole 244 are connected to the air groove 239 to form the upper air passage structure.

[0077] When the sliding rod 234 needs to descend, an external air source introduces gas into the air groove 239 through the second air hole 243. Simultaneously, the gas in the pushing chamber 232 is discharged from the first exhaust hole 241. The air pressure difference pushes the sliding rod 234 downward until it extends out of the through hole 220 to complete the clamping of the conduit. When the sliding rod 234 needs to rise, an external air source introduces gas into the pushing chamber 232 through the first air hole 242. The gas in the air groove 239 is discharged from the second exhaust hole 244. The air pressure difference pushes the sliding rod 234 upward until it is completely retracted into the pushing chamber.

[0078] In one embodiment, there are multiple fastening bolts 238, which are spaced apart along the outer periphery of the outer sleeve 236.

[0079] Specifically, multiple fastening bolts 238 are evenly spaced along the outer periphery of the outer sleeve 236, and each fastening bolt 238 passes through the sealing seat 237 and forms a threaded connection with the mounting seat 210. Through multi-point fastening, a stable and reliable sealing connection is ensured between the sealing seat 237 and the outer sleeve 236, and between the outer sleeve 236 and the mounting seat 210.

[0080] During actual assembly, the arrangement of multiple fastening bolts 238 provides a uniform tightening force. When the fastening bolts 238 are tightened, the pressure on the sealing seat 237 is evenly distributed on its contact surface with the outer sleeve 236, while the contact between the outer sleeve 236 and the mounting base 210 is also tighter. This multi-point fastening structure makes the entire housing 231 assembly form a stable whole, effectively preventing loosening or leakage during operation.

[0081] In one embodiment, the cover body 100 has a plurality of spaced ventilation holes 140 on both sides of the material passage 120, and all ventilation holes 140 are connected to the receiving cavity 110.

[0082] Specifically, multiple vents 140 are provided on both sides of the material conveying trough 120. These vents 140 are distributed at intervals along the side walls to form a ventilation structure. The vents 140 ensure that the interior of the material conveying trough 120 is connected to the external environment by airflow, thus preventing the formation of a closed space.

[0083] When the conduit passes through the feed trough 120, airflow disturbances may occur inside the feed trough 120 due to the movement of the conduit and the clamping action of the sliding rod 234. Through the vents 140 on both side walls, the gas inside the feed trough 120 can exchange with the external environment, maintaining internal air pressure balance. At the same time, the spacing of the vents 140 ensures uniform airflow exchange and avoids localized air pressure anomalies.

[0084] It should be specifically and clearly stated that the vent 140 is an oblong vent.

[0085] In practical applications, the unique structure of the oblong orifice gives it distinctive ventilation performance. When airflow passes through the oblong orifice, its special shape guides the airflow. The wider areas at both ends facilitate airflow entry and exit, while the narrower middle area throttles the airflow, regulating its speed. This structure effectively prevents interference with the conduit transmission caused by excessively fast airflow.

[0086] Through the above-described waist-shaped hole structure, this embodiment has the following technical effects: First, the special shape of the waist-shaped hole provides good ventilation while avoiding airflow turbulence; second, the waist-shaped hole has a larger effective ventilation area than the circular hole, improving ventilation efficiency; third, the waist-shaped hole has better structural strength and is less prone to cracking due to stress concentration, solving the technical problems of low ventilation efficiency and easy airflow interference of traditional circular vent holes, and significantly improving the airflow environment in the material passage trough.

[0087] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
