Description

Technical Field

[0001] The utility model belongs to the field of suspension conveying, in particular to a stopping mechanism of a suspension conveying device. Background Art

[0002] Overhead conveyors are a common type of industrial automation equipment, primarily used for the automatic transport of materials. These systems typically consist of a conveyor belt or chain suspended from a track, with materials conveyed via hooks or pulleys attached to the belt. In industrial production, overhead conveyors are widely used in production lines such as packaging, equipment, painting, and welding. The stop mechanism is a key component of overhead conveyors, responsible for stopping the conveyor when necessary to facilitate loading and unloading, inspection, or maintenance.

[0003] Some existing suspended conveying devices cannot accurately detect whether the moving position of the conveying group or pulley group of the loaded material has reached the stop mechanism in a timely manner, and cannot ensure that the walking mechanism can stop at the correct position. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a stopping mechanism for a suspension conveying device, the purpose of which is to timely detect when a pulley block reaches the stopping mechanism and control the telescopic device to interfere with the walking trajectory of the pulley block.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a stopping mechanism of a suspension conveying device, comprising a stopping mechanism, a traveling mechanism, and a traveling track;

[0006] The stopping mechanism includes a mounting frame, a telescopic device and a sensor; the mounting frame is mounted on the walking track, and the telescopic device is mounted on the mounting frame;

[0007] The walking mechanism includes at least one pulley set;

[0008] The pulley block can be slidably installed on the walking track; when the walking mechanism moves into the detection range of the sensor, the sensor is triggered to make the telescopic device block the walking mechanism.

[0009] It mainly consists of three parts: a stopping mechanism, a traveling mechanism and a traveling track. The purpose of the invention is to stop the traveling mechanism from sliding due to gravity or inertia. Through the setting of the stopping mechanism, when the traveling mechanism moves into the detection range of the sensor, it can timely control the telescopic device through sensing to achieve control of whether the entire suspension conveying device moves forward or not.

[0010] Furthermore, the telescopic device comprises a cylinder and a blocking rod; a slidable blocking rod is installed in the cylinder body of the cylinder; power gas is introduced into the cylinder body to make the telescopic device extend the blocking rod.

[0011] The system is mounted on the track via a mounting bracket. When the extended portion of the blocking rod contacts the travel mechanism, it interferes with the travel mechanism's trajectory. Therefore, when the travel mechanism needs to stop, power is introduced into the cylinder of the stopping mechanism to control the extension of the blocking rod, preventing the travel mechanism from continuing to move. When the travel mechanism needs to continue moving, the blocking rod is retracted, and the travel mechanism can continue to operate without being obstructed.

[0012] Furthermore, the mounting frame includes a fixed plate and an adjusting frame; the fixed plate is fixedly connected to the walking track; the adjusting frame includes a connecting plate, a top plate, and an adjusting plate; the cylinder is installed on the connecting plate; a through hole is provided on the adjusting plate, and the blocking rod passes through the through hole; an adjusting hole is provided on the adjusting plate, and the adjusting hole is long and strip-shaped, and a fastener passes through the adjusting hole to fix the adjusting plate to the fixed plate.

[0013] The fixed plate is installed on the walking track to fix the track. The adjustment plate is provided with adjustment holes. The position of the adjustment plate can be adaptively adjusted according to different walking mechanisms, thereby adjusting the position of the telescopic device and controlling the different telescopic heights of the blocking rod, thereby improving adaptability.

[0014] Furthermore, the mounting frame also includes a locking plate; the locking plate is integrally formed and has an L-shaped cross-section; the bottom surface of the locking plate is fixedly connected to the top plate of the adjustment frame; the side of the locking plate has multiple limiting holes; the limiting holes are arranged up and down, and the fasteners are fixed to the fixing plate through the limiting holes.

[0015] While the adjustment hole of the adjustment plate is being adjusted in height, the limit hole of the locking plate is also being adjusted in height. Since the adjustment hole on the adjustment plate is adjusted by sliding, the added locking plate plays a fixing role, preventing the fasteners in the adjustment hole from loosening due to the vibration caused by the collision of the walking mechanism during the blocking process, thereby fixing the height position of the telescopic device and ensuring the normal operation of the conveying device.

[0016] Furthermore, the sensor is mounted on the adjustment plate, with the detection end of the sensor facing the walking track.

[0017] The sensor is installed on the adjustment frame, and the detection end of the sensor faces the walking track. When the walking mechanism enters the detection range, the detection end takes effect and promptly determines the precise timing of extending the control blocking rod.

[0018] Furthermore, the walking mechanism includes a crossbeam, a pair of fixed rods, and a pair of pulley groups; a pulley group is installed at the upper end of each fixed rod, and the lower end of each fixed rod is connected to the crossbeam; the pulley group includes a connecting frame and a walking wheel; the connecting frame is installed at the upper end of the fixed rod; the walking track includes a guide rail and a walking groove (32), and the guide rail is installed at the bottom of the walking groove (32); the walking wheel is rotatably installed on the connecting frame, and the walking wheel is slidably installed on the guide rail.

[0019] By setting two pulley groups in front and back to move on the track, and by fixing and connecting through the crossbeam, a certain degree of stability can be ensured. By setting two groups of sliding groups in the sliding process, it can be ensured that it will not sway and cause unstable phenomena due to the inertia imbalance of sudden stop.

[0020] Further, the crossbeam is provided with a hook at one end.

[0021] The walking mechanism relies on the hook for suspending the conveyed goods. The hook is firmly installed on the crossbeam through fasteners, providing a place where goods can be placed. The hook drives the walking wheels to slide while suspending the goods to be conveyed.

[0022] Further, each pulley group further comprises two pairs of guide wheels, each pair of guide wheels being composed of two pulleys arranged vertically, and the guide wheels being transversely installed at the lower end of the connecting frame; the walking track further comprises a guide groove, the inner side walls of the two sides of the guide groove forming limiting surfaces, and the guide wheels being placed between the limiting surfaces of the two sides.

[0023] The guide wheels are between the limiting surfaces of the two sides of the guide groove, and the walking wheels are placed on the guide rail to slide. When the pulley group deviates to one side, the guide wheels will touch the limiting surface of the inner wall of that side, thereby preventing the walking wheels from deviating, so that the walking wheels can always move along the guide rail, ensuring that the running track of the conveying device is within a controllable safe range.

[0024] Further, the lower end of the fixing rod is provided with a threaded section, and a pair of fasteners are arranged on the threaded section, and the crossbeam is clamped between the two fasteners; the crossbeam is provided with an installation hole extending vertically therethrough, and the fixing rod passes through the installation hole and is fixed on the crossbeam by the fasteners at both ends.

[0025] The fixing rod firmly connects the pulley group to the crossbeam by the fasteners at both ends, thereby fixing the pulley group so that the walking wheels can stably carry heavy objects for conveying and sliding, ensuring the stability and safety of the entire conveying device. In addition, the fixing rod is provided with a threaded section for adjusting the walking mechanism at different heights so that it can slide on a horizontal line.

[0026] Further, a section of the walking track adjacent to the stopping mechanism is a stopping section, and the stopping section is arranged obliquely, with the walking mechanism being located at the low end of the stopping section, and the height of the stopping section being lower as it is closer to the walking mechanism.

[0027] A small section of the walking mechanism is provided with an oblique stopping section adjacent to the stopping mechanism. The walking mechanism slides on the oblique stopping section relying on gravity. When the walking mechanism moves to the lowest point of the stopping section, it reaches the stopping mechanism. The stopping mechanism detects the walking mechanism entering the detection range, thereby extending the blocking rod to interfere with the walking track of the walking mechanism in time when the walking mechanism reaches the stopping mechanism. This can effectively promote the smooth operation of the suspended conveying device.

[0028] Advantages

[0029] In this utility model, when the traveling mechanism enters the detection range of the sensor on the stop mechanism, the sensor controls the telescopic device to extend a blocking rod to interfere with the traveling mechanism's trajectory, ensuring that the traveling mechanism stops at the designated position, thereby ensuring smooth operation of the entire conveyor. The stop mechanism can also be adjusted in height to suit different traveling mechanisms, improving the adaptability of the stop mechanism and enabling timely emergency braking to prevent accidents, thus ensuring safety during the suspended conveying process.

[0036] Example 1

[0037] like Figure 1 The illustrated overhead conveyor includes a stopping mechanism 1, a traveling mechanism 2, and a traveling track 3. The traveling track 3 includes a guide rail 31, a traveling groove 32, and a guide groove 33. The guide rail 31 divides the interior space of the traveling track 3 into the traveling groove 32 and the guide groove 33. The traveling groove 32 is above the guide groove 33, and the inner sidewalls of the guide grooves form limiting surfaces.

[0038] like Figure 2The illustrated traveling mechanism 2 includes a crossbeam 23, a pair of fixed rods 22, and a pair of pulley blocks 21. A pulley block 21 is mounted on the upper end of each fixed rod 22, and the lower end of each fixed rod 22 is connected to the crossbeam 23. The pulley blocks 21 include a connecting frame 211 and running wheels 212. The connecting frame 211 is mounted on the upper end of the fixed rod 22. The running wheels 212 are mounted on the outside of the middle position of the connecting frame 211 via rollers. The running wheels 212 slide on guide rails 31, and the sliding space of the running wheels 212 is a running groove 32. Each pulley block 21 also includes two pairs of guide wheels 213. Each pair of guide wheels 213 consists of two upper and lower pulleys. The guide wheels 213 are mounted horizontally at the lower end of the connecting frame 211. The guide wheels 213 are positioned between the limiting surfaces on both sides of the guide groove 33. When the walking wheel 212 deviates from the center line during the sliding process, the deviation reaches a certain degree, and the guide wheel 213 touches the limiting surface on that side, that is, the walking wheel 212 is controlled not to deviate excessively from the sliding, and the walking wheel 212 is guided to return to the prescribed walking trajectory in time, effectively ensuring the smooth progress of the entire suspension conveying process.

[0039] The lower end of the fixing rod 22 is provided with a threaded section with a pair of fasteners mounted thereon, between which the crossbeam 23 is clamped. A through-hole is provided on the crossbeam 23, through which the fixing rod 22 passes, and is secured to the crossbeam 23 at both ends by fasteners. A hook is mounted on one end of the crossbeam 23 for placing items to be transported. Installing a hanging device for transport saves floor space, conserves resources, and improves transportation efficiency.

[0040] The section of track 3 adjacent to the stop mechanism 1 is the stop section. This section is tilted, and the travel mechanism 2 slides on the guide rail 31 to the lower end of the stop section. This ensures that the travel mechanism 2 stops accurately at the lowest point of the stop section, giving the sensor 13 sufficient detection time to control the telescopic device 12 to react. The closer the stop section is to the travel mechanism 2, the lower its height.

[0041] like Figure 3 As shown, the stopping mechanism 1 comprises a mounting frame 11, an extension mechanism 12, and a sensor 13. The mounting frame 11 is mounted on the running track 3, and the extension mechanism 12 is mounted on the mounting frame 11. The extension mechanism 12 comprises a cylinder 121 and a blocking rod 122. The blocking rod 122 is slidably mounted within the cylinder body of the cylinder 121. Power is introduced into the cylinder 121 to extend the extension mechanism 12 beyond the blocking rod 122. The extension mechanism 12 can be positioned to block the running track without damaging the running track or affecting operation, as long as it effectively blocks the running track.

[0042] The cylinder 121 mainly uses air pressure to convert into kinetic energy, and relies on controlling the pressure of the left and right air chambers to control the extension and contraction of the piston rod and thus the extension and contraction of the blocking rod 122. When the right-end air valve is opened to inflate, the gas on the left end is discharged, the pressure decreases, and the air pressure pushes the piston and the piston rod to the left, which appears to be extended; when the opposite operation is performed, the piston rod moves to the right, which appears to be contracted. The control of the cylinder is mainly carried out by the solenoid valve, and the cylinder 121 is connected to the sensor 13 through electromagnetic induction. The sensor 13 mainly uses a photoelectric sensor type, which uses the propagation and reflection of light to determine the position and state of an object. The photoelectric detection method has the advantages of high precision, fast response, and non-contact, and can measure many parameters. The photoelectric sensor has a simple structure and flexible and diverse forms.

[0043] like Figure 3 and Figure 4 As shown, the mounting frame 11 includes a fixed plate 111 and an adjustment frame 112; the fixed plate 111 is fixedly connected to the running track 3; the adjustment frame 112 includes a connecting plate 1121, a top plate 1122, and an adjustment plate 1123; the cylinder 121 is mounted on the connecting plate 1121; the adjustment plate 1123 is provided with a through hole, through which the blocking rod 122 passes; the adjustment plate 1123 is provided with an adjustment hole 11231, which is an elongated strip, and a fastener passes through the adjustment hole 11231 to fix the adjustment plate 1123 to the fixed plate 111. The mounting frame 11 also includes a locking plate 113; the locking plate 113 is integrally formed and has an L-shaped cross-section; the bottom surface of the locking plate 113 is fixedly connected to the top plate 1122 of the adjustment frame 112; the side surface of the locking plate 113 has a plurality of limiting holes 1131; the limiting holes 1131 are arranged vertically, and the fastener passes through the limiting holes 1131 to fix the fixing plate 111. The sensor 13 is mounted on the adjustment plate 1123 , with the detection end of the sensor 13 facing the walking track 3 .

[0044] The fixed plate 111 is fixedly installed on the upper and lower ends of the walking track 3, playing a stabilizing role. The adjusting frame 112 is used to connect the telescopic device 12 and the fixed plate 111, and the locking plate 113 plays a role in strengthening the connection. The adjusting hole 11231 on the adjusting plate 1123 is adjusted for different walking mechanisms 2 to adapt to different blocking heights. However, since the fasteners are in sliding adjustment in the adjusting hole 11231, the vibration of the movement and the collision caused by the blocking will cause the fasteners to loosen, which may cause the blocking position to deviate and cause an accident. Therefore, a plurality of limiting holes 1131 are installed on the locking plate to further fix the adjusting plate 1123, thereby ensuring safety during transportation and improving stability.
