Description

Technical Field

[0001] This utility model relates to the field of suspended conveyors, and specifically to a deployable stopper for suspended conveyor lines. Background Technology

[0002] In modern industrial production, overhead conveyor lines are widely used in the transmission and handling of various materials and products, playing a crucial role in achieving automated production processes and improving production efficiency. As an important component of overhead conveyor lines, stop devices are primarily used for precise stopping control of the conveyor vehicles to ensure the smooth and orderly conduct of subsequent assembly, testing, or packaging processes.

[0003] Existing suspension conveyor stopping technologies primarily rely on physical blocking principles, placing rigid blocks at specific locations on the track. When the conveyor car reaches the block, its front-end collision mechanism directly impacts the block, forcing the car to stop through friction or mechanical restraint. This method is simple in structure and low in cost, but the car experiences a huge direct impact force at the moment of stopping, generating noise and potentially causing deformation, wear, or even damage to the block, the car's collision components, and the conveyor track itself. This significantly increases maintenance costs and downtime. Fixed blocks require manual intervention or complex mechanisms to remove and release the car, making rapid automatic reset impossible. Another method involves installing a liftable blocking arm or pin under the track. When a stop is needed, the blocking arm rises and inserts into the blocking hole or groove at the bottom of the car, locking it and preventing it from moving forward; when release is needed, the blocking arm lowers. While this method allows for automatic reset, its lifting mechanism is typically complex and space-consuming. The blocking arm or pin is prone to deformation and damage after repeated locking, resulting in high maintenance costs.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: To overcome the above shortcomings, the purpose of this utility model is to provide a deployable stop for suspended conveyor lines. The slow-stop component is deployed and retracted via an opening and closing mechanism, achieving automatic control of the conveyor vehicle's operation and stopping. The slow-stop component features a ramp, allowing the conveyor vehicle to move obliquely upwards along the ramp via a lifting mechanism, disengaging from the drive shaft and avoiding rigid collisions, thus reducing impact. Simultaneously, a buffer is installed on the slow-stop component to further mitigate the impact when the conveyor vehicle stops, reducing noise. Furthermore, the buffer is adjustable to the adjusting seat, facilitating adjustments to the buffering force according to actual needs, thereby effectively reducing component wear and lowering maintenance costs.

[0006] Technical Solution: This utility model provides a deployable stopper for a suspended conveyor line, comprising: a frame, the frame being erected on the conveyor track, the conveyor track including a drive shaft, the conveyor vehicle being suspended on the conveyor track, the drive shaft being used to drive the conveyor vehicle to move on the conveyor track; an opening and closing mechanism and a pair of slow-stop components, the opening and closing mechanism being mounted on the frame and used to drive the slow-stop components to unfold and close, the slow-stop components including a ramp platform, the ramp platform being arranged along the moving direction of the conveyor vehicle, and a lifting rod mechanism being provided at the end of the conveyor vehicle in the forward direction; when the opening and closing mechanism drives the slow-stop components to unfold, the conveyor vehicle moves normally on the conveyor track; when the slow-stop components are driven to close, the lifting rod mechanism contacts the ramp platform and moves obliquely upward along the ramp platform, the conveyor vehicle is lifted and stops moving after being disengaged from the drive shaft. By utilizing the physical structure of the ramp platform, the vehicle is stopped through the sliding lifting of the lifting mechanism, avoiding hard mechanical collisions and reducing equipment wear. During the stopping process, the conveyor is lifted off the drive shaft, cutting off the motion from the power source, ensuring the stability of the stopped state. The frame is erected on the conveyor track and matches the drive shaft and the conveyor's suspension structure, making it easy to integrate into the existing suspended conveyor system without changing the original track layout.

[0007] Furthermore, in this application, a deployable stopper for a suspended conveyor line has an inverted U-shaped frame bolted to a conveyor track. The opening and closing mechanism includes a cylinder, a pair of upper connecting rods, a pair of lower connecting rods, and a pair of hinge seats. The cylinder is horizontally positioned at the upper end of the frame, and the pair of hinge seats are correspondingly installed at the bends at the upper end of the frame. The upper connecting rods are pivotally connected to the hinge seats. The bottom end of the cylinder and the output shaft end are respectively hinged to one end of the corresponding upper connecting rod, and the other end of the upper connecting rod is hinged to one end of the corresponding lower connecting rod. The other end of the lower connecting rod is pivotally connected to a mounting seat on a corresponding deceleration assembly. The deceleration assembly is installed at the lower end of the frame and is rotatably connected to the frame. When the cylinder extends, it drives the upper connecting rods to rotate, the lower connecting rods to move downwards in conjunction, and thus drives the deceleration assembly to retract. When the cylinder retracts, it drives the upper connecting rods to rotate, the lower connecting rods to lift upwards in conjunction, and thus drives the deceleration assembly to deploy. A pair of upper connecting rods, lower connecting rods, and deceleration components are symmetrically arranged and driven by a single cylinder to ensure that the deceleration components on both sides open and close synchronously. When the cylinder extends, it pushes the upper connecting rod to rotate around the hinge seat, which in turn moves the lower connecting rod downward and causes the deceleration components to retract inward. At this time, the ramp is in place, and the lifting mechanism of the subsequent conveyor moves diagonally upward along the ramp. After the conveyor is lifted and disengaged from the power of the drive shaft, it stops moving.

[0008] Furthermore, in a suspended conveyor line deployment stop according to this application, a buffer component is also installed on the stopping assembly. The buffer component is arranged along the moving direction of the conveyor vehicle. When the conveyor vehicle moves to the ramp, the buffer component abuts against the blocking sheet metal at the front end of the conveyor vehicle, stopping the conveyor vehicle. When the conveyor vehicle contacts the ramp, the buffer component contacts the blocking sheet metal first, absorbing the inertial impact force of the conveyor vehicle through elastic deformation, gradually reducing the vehicle speed, and finally achieving a smooth stop, avoiding the instantaneous impact caused by rigid collision.

[0009] Furthermore, in this application, a deployable stopper for a suspended conveyor line includes an adjusting seat installed under the ramp. The buffer component includes a cylinder with a piston rod extending outward. A impact head is installed at the front end of the piston rod, and a spring is sleeved on the piston rod. The spring is located between the cylinder and the impact head. The cylinder passes through the adjusting seat, and its outer circumference is threaded, allowing for adjustable movement with the adjusting seat. By rotating the cylinder, its extension length in the adjusting seat is changed using the threaded structure, thereby adjusting the pre-compression of the spring. Different spring pre-tensions result in different resistances of the buffer component to the conveyor vehicle, allowing for adjustments to the horizontal position of the buffer component for conveyor vehicles with different loads and speeds. The threaded connection between the adjusting seat and the cylinder also allows for fine-tuning of the buffer component's horizontal position. Combined with the slope of the ramp, the final stopping position of the conveyor vehicle can be controlled.

[0010] Furthermore, in one application of a deployable stopper for a suspended conveyor line, the impact head is covered with a sound-absorbing sleeve made of rubber. The sound-absorbing sleeve, as an extension of the buffer structure, forms a flexible contact layer between the impact head and the conveyor vehicle, further mitigating the impact force and avoiding localized stress concentration caused by rigid contact.

[0011] Furthermore, this application discloses a deployable stopper for a suspended conveyor line. The ramp includes a ramp, a platform, and side baffles. The platform is horizontally positioned, the ramp slopes downwards, and the side baffles are vertically positioned on the platform along the direction of the conveyor vehicle's movement, located away from the conveyor track. The ramp gradually cuts off the drive shaft power, avoiding impacts caused by sudden stops and achieving smooth deceleration. The side baffles prevent the conveyor vehicle from sliding or tipping outwards due to inertia, collisions, or track deviation during stopping, providing reliable lateral restraint for the conveyor vehicle.

[0012] Furthermore, in one embodiment of the suspended conveyor line deployment stop, the conveyor track further includes a pair of pressure rails, with a reinforcing plate on the lower outer side of each pressure rail. The reinforcing plate serves to absorb kinetic energy impacts received by the frame.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. The present invention discloses a deployable stopper for a suspended conveyor line. The deployable stopper is driven by an opening and closing mechanism to deploy and close the slow-stop component. Combined with the physical lifting structure of the ramp and lifting rod mechanism, the conveyor vehicle is disconnected from the drive shaft power when it stops, avoiding direct impact from traditional rigid blocks. This significantly reduces the impact force, wear and noise between equipment. At the same time, the adjustable connection between the buffer and the adjusting seat can adjust the buffer force according to the actual working conditions such as the weight and speed of the conveyor vehicle, further optimizing the smoothness of the stopping process and effectively reducing maintenance costs and downtime.

[0015] 2. The deployable stopper for a suspended conveyor line described in this utility model uses an inverted U-shaped frame bolted to the conveyor track, which can be quickly integrated without changing the original track layout, making installation very convenient. The cylinder-driven linkage transmission structure ensures that the slow-stop components on both sides open and close synchronously, achieving automated and precise control. Furthermore, the side baffles and platform structure of the ramp provide lateral constraints and stable support for the conveyor vehicle, ensuring the reliability and safety of the stopped state.

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This embodiment provides a specific application scenario for a deployable stopper used in a suspended conveyor line, combined with... Figures 1-6 The structure shown is implemented as follows:

[0031] I. Overall Structure Installation

[0032] The conveyor track is connected to the frame: The conveyor track 1 is arranged horizontally, and its internal drive shaft 11 is driven to rotate by a motor. The conveyor trolley 2 is suspended below the conveyor track 1 by a hoisting structure. The inverted U-shaped frame 3 is fixed to the outside of the conveyor track 1 by bolts. A pair of slow-stop components 5 are installed on both sides of the lower end of the frame 3, and the opening and closing mechanism 4 is installed on the upper end.

[0033] Conveyor vehicle structure: The end of the conveyor vehicle 2 in the forward direction is provided with a lifting rod mechanism 21, and the front end is welded with a blocking sheet metal 22. When the conveyor vehicle 2 moves along the conveyor track 1, the drive shaft 11 drives the conveyor vehicle 2 to move synchronously.

[0034] II. Driving Principle of Opening and Closing Mechanism

[0035] Cylinder-driven linkage system: The cylinder 41 of the opening and closing mechanism 4 is horizontally mounted in the middle of the upper end of the frame 3 (e.g., Figure 3 (As shown) Its output shaft end is hinged to the right upper connecting rod 42, and the bottom end of the cylinder 41 is hinged to the left upper connecting rod 42. A pair of hinge seats 44 are fixed at the left and right corners of the upper end of the frame 3 respectively. The other end of the upper connecting rod 42 is connected to the hinge seat 44 through a pivot. One end of the lower connecting rod 43 is hinged to the upper connecting rod 42, and the other end is connected to the mounting seat 52 on the slow stop assembly 5 through a pivot.

[0036] Deployed state: When cylinder 41 retracts, it drives the upper connecting rod 42 to rotate upward around the hinge seat 44, causing the lower connecting rod 43 to lift, thereby pushing the slow-stop assembly 5 to deploy outward (e.g. Figure 2 , Figure 4(As shown). At this time, the ramp 51 of the slow-stop component 5 is away from the movement path of the conveyor 2, and the conveyor 2 can move normally along the conveyor track 1. The lifting mechanism 21 will not contact the ramp 51.

[0037] Retracted state: When cylinder 41 extends, it pushes upper connecting rod 42 to rotate downward around hinge seat 44, and lower connecting rod 43 moves downward in response, causing slow-stop component 5 to retract inward (e.g. Figure 1 , Figure 3 (As shown). At this time, the ramp 51 is located on the forward path of the conveyor 2, ready to stop the conveyor 2.

[0038] III. Stopping process of the slow-stop component

[0039] Inclined platform structure: The inclined platform 51 of the deceleration assembly 5 consists of an inclined ramp 511, a platform 512, and a side baffle 513. The inclined ramp 511 is inclined downwards, the platform 512 is horizontally connected to the end of the inclined ramp 511, and the side baffle 513 is vertically fixed to the side of the platform 512 away from the conveyor track 1. When the conveyor 2 moves to the deceleration assembly 5 in its retracted state, the lifting mechanism 21 first contacts the inclined ramp 511 and moves obliquely upwards along the ramp, driving the conveyor 2 to lift as a whole, thus disengaging the conveyor 2 from the power of the drive shaft 11 (e.g., Figure 5 , Figure 6 (As shown).

[0040] The buffering function of the buffer component: The buffer component 53 on the buffer assembly 5 is arranged along the moving direction of the conveyor 2. Its cylinder 531 passes through the adjusting seat 54, and the threads on the outer periphery of the cylinder are threadedly connected to the adjusting seat 54. The impact head 533 at the front end of the piston rod 532 is wrapped with a rubber silencing sleeve 535, and a spring 534 is wrapped around the piston rod 532. The two ends of the spring 534 abut against the cylinder 531 and the impact head 533, respectively. When the conveyor 2 is lifted, the blocking sheet metal 22 contacts the impact head 533, the spring 534 is compressed to absorb the impact energy, and the silencing sleeve 535 reduces the collision noise, so that the conveyor 2 stops smoothly on the platform 512.

[0041] IV. Buffer Force Adjustment and Track Reinforcement

[0042] Buffer adjustment: By rotating cylinder 531, its extension length in adjusting seat 54 can be adjusted, thereby changing the pre-compression of spring 534. When a greater buffering force is needed, cylinder 531 is rotated outward to increase spring preload; conversely, it is rotated inward to reduce buffering resistance, to accommodate conveyor vehicles 2 with different loads.

[0043] Track reinforcement: Reinforcing plates 13 are welded to the lower outer side of the pressure rails 12 on both sides of the conveyor track 1. When the conveyor 2 stops, the impact kinetic energy of the frame 3 is distributed to the overall structure of the conveyor track 1 through the reinforcing plates 13, reducing the risk of track deformation.

[0044] V. Work Process Summary

[0045] When the conveyor 2 needs to operate normally, the cylinder 41 retracts, the drive slow stop assembly 5 unfolds, and the conveyor 2 moves along the conveyor track 1 with the drive shaft 11.

[0046] When the conveyor 2 needs to stop, the cylinder 41 extends, the slow stop component 5 retracts, the lifting mechanism 21 is lifted along the ramp 51, the conveyor 2 is disengaged from the drive shaft 11, and at the same time the buffer component 53 achieves a smooth buffer stop through the spring 534 and the muffler sleeve 535.

[0047] To adjust the stopping buffer effect, the preload of the spring 534 can be adjusted on the adjusting seat 54 by rotating the cylinder 531 of the buffer component 53.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
