Description

Technical Field

[0001] This utility model relates to the technical field of bench testing facilities, and in particular to an automatic escape device for locking a drum bench. Background Technology

[0002] In the existing technology, the vehicle fixing device on the two-wheel drive drum stand generally adopts a rigid mechanical locking mechanism, such as a threaded fastening lock or a worm gear transmission mechanism.

[0003] The existing locking mechanism poses a significant safety hazard: in the event of an emergency during vehicle testing, such as a vehicle fire, the rapid emergency decoupling mechanism of the vehicle locking system in the test bench system cannot be operated. The presence of a burning vehicle on the drum could cause irreversible structural damage to the test bench system, potentially leading to equipment destruction. Furthermore, if operators risk approaching the vehicle to manually unlock it, there is not only a significant personal safety risk but also a substantial increase in emergency response time. Utility Model Content

[0004] To address the aforementioned issues, this application provides a structurally sound automatic traction device for locking a rotating drum platform, thereby providing stable and reliable vehicle fixation and enabling rapid unlocking via remote control in emergency situations. This greatly facilitates the quick and safe separation of the vehicle from the platform, ensuring personnel safety.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An automatic escape device for a rotating drum platform includes a support platform. Pull-up posts are installed at intervals on the left and right sides of the front of the support platform. One end of a strap assembly is attached to a tow hook on a vehicle, and the other end is attached to a locking hook on the pull-up post. The locking hook is driven by a power component to move up and down, switching between locked and unlocked states. Movable seats are installed at intervals on the rear of the support platform. These movable seats are driven by a longitudinal movement drive component to move longitudinally along the vehicle. Wedge-shaped baffles are installed at intervals on the left and right sides of each movable seat. The wedge-shaped baffles on the front and rear movable seats are arranged in pairs, abutting against the corresponding tires of the vehicle in the front-rear direction. The device also includes a lateral locking mechanism for locking the movable seats.

[0007] As a further improvement to the above technical solution:

[0008] The support platform is provided with left and right spaced support beams, and the movable seat is movably mounted on the support beams; the lateral locking mechanism includes a cylinder installed on the bottom surface of the movable seat, with the cylinder output end facing the support beam.

[0009] The side of the support beam is provided with a T-shaped channel, and a T-shaped component is installed at the output end of the cylinder. The T-shaped component is fitted into the T-shaped channel to provide guidance for the movement of the movable seat.

[0010] The movable seat is recessed in the middle, and a nut is installed on the bottom surface of the movable seat; at the same time, a two-way lead screw is threaded onto the front and rear nuts, and the end of the two-way lead screw is powered to a motor. The motor drives the two-way lead screw to rotate, causing the front and rear movable seats to move towards each other or away from each other at the same time, thus forming a longitudinal movement drive assembly.

[0011] The wedge-shaped baffle is configured with an upward-expanding slope on the side facing the tire, and the left and right edges of the slope extend upward to form convex ridges, which are located on both sides of the tire.

[0012] The top surface of the movable seat and the bottom surface of the wedge-shaped baffle are fitted together to form a transverse moving structure.

[0013] A smoke detector is also installed on the support platform.

[0014] The strap assembly includes two sets arranged from the vehicle tow hook toward the two tension posts; the structure of a single strap assembly is as follows: it includes a movable strap, the fixed end of which is attached to the tow hook, and the movable end of which is wrapped around a ratchet tensioner, which adjusts the length of the movable strap and then tightens it; it also includes a fixed strap, one end of which is attached to the locking hook via a hook, and the other end of which is fitted with a ratchet tensioner.

[0015] The structure of the tension pile is as follows: it includes a pile body, a sliding support installed inside the pile body via a vertical guide rail, and the sliding support is locked and fixed after adjusting its height along the vertical guide rail; a cylinder with its output end arranged vertically downward is installed inside the sliding support, a moving block is installed at the output end of the cylinder, and a locking hook is installed laterally on the moving block. The locking hook passes outward through the sliding support and the pile body and then bends downward; a support platform extends laterally from the bottom surface of the sliding support, and the movement of the moving block causes the locking hook to move downward until the outer end of the locking hook abuts and fits against the support platform.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] During bench testing, this invention uses a wedge-shaped baffle combined with a transverse locking mechanism and a strap assembly combined with tension piles to stably and reliably fix the vehicle. In case of emergencies, it can be remotely controlled for quick unlocking without requiring personnel to approach the vehicle to manually unlock it, which greatly helps to achieve rapid and safe separation between the vehicle and the bench and ensures personnel safety.

[0018] This utility model also has the following advantages:

[0019] The T-shaped component in the transverse locking mechanism is fitted with the T-shaped channel on the support beam. While realizing the longitudinal movement guidance function, it can also make the T-shaped component and the T-shaped channel keep against each other through the action of the cylinder in the transverse locking mechanism, so as to achieve transverse locking. The overall structure is simple, reasonable and ingenious, and can also realize automatic and fast unlocking, which is especially suitable for dealing with emergencies.

[0020] After the lateral locking mechanism unlocks the lateral lock, the motor in the longitudinal movement drive assembly works, the bidirectional lead screw rotates, and in conjunction with the helical pair with the nut, it drives the two moving seats to move in opposite directions, so that the wedge baffles move away from the tires, releasing the fixation on the vehicle tires and effectively helping to get out of trouble quickly.

[0021] When the moving block in the tension pile moves downward and abuts against the support, it helps to fix the hook in the strap assembly. After the moving block moves in the opposite direction and disengages from the support, the hook in the strap assembly is released from its lock and can freely disengage from the support and tension pile, thus achieving automatic and rapid unlocking of the front of the vehicle.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, the automatic escape device for locking the drum platform in this embodiment includes a support platform 7. Pull-up posts 8 are installed at intervals on the left and right sides of the front of the support platform 7. One end of a strap assembly 9 is attached to the vehicle's tow hook, and the other end is attached to the locking hook 86 of the pull-up post 8. The locking hook 86 is driven by a power component to move up and down to switch between locked and unlocked states. Movable seats 5 are installed at intervals on the rear of the support platform 7. The movable seats 5 are driven by a longitudinal movement drive assembly 2 to move longitudinally along the vehicle. Wedge-shaped baffles 4 are installed at intervals on the left and right sides of each movable seat 5. The wedge-shaped baffles 4 on the front and rear movable seats 5 are arranged in pairs and abut against the corresponding tires of the vehicle in the front-rear direction. The device also includes a lateral locking mechanism 3 for locking the movable seats 5.

[0037] In this embodiment, during bench testing, the wedge baffle 4 combined with the lateral locking mechanism 3 and the strap assembly 9 combined with the tension pile 8 are used to stably and reliably fix the vehicle. In case of emergencies, it can be remotely controlled for quick unlocking.

[0038] In this embodiment, the tension pile 8 can be installed on the support platform 7 via a mounting structure such as a sliding groove. The spacing between two tension piles 8 can be adjusted to match different types of vehicles. After the position of the tension pile 8 is adjusted, bolts or other fasteners can be used to lock and fix the tension pile 8 relative to the support platform 7.

[0039] The support platform 7 is provided with left and right spaced support beams 1, and the movable seat 5 is movably mounted on the support beams 1; the transverse locking mechanism 3 includes a cylinder installed on the bottom surface of the movable seat 5, with the cylinder output end facing the support beam 1.

[0040] In this embodiment, after the movable seat 5 moves into place relative to the support beam 1, the cylinder actuates it laterally against the support beam 1, thus forming a lateral locking and fixing.

[0041] like Figure 3 As shown, a T-shaped channel 11 is provided on the side of the support beam 1, and a T-shaped component 31 is installed at the output end of the cylinder. The T-shaped component 31 is fitted into the T-shaped channel 11 to provide guidance for the movement of the movable seat 5.

[0042] In this embodiment, the T-shaped part 31 in the transverse locking mechanism 3 is fitted with the T-shaped channel 11 on the support beam 1. While realizing the longitudinal movement guidance function, it can also make the T-shaped part 31 and the T-shaped channel 11 keep against each other through the action of the cylinder in the transverse locking mechanism 3, so as to realize transverse locking. The overall structure is simple, reasonable and ingenious, and can also realize automatic and fast unlocking, which is especially suitable for dealing with emergencies.

[0043] The middle part of the movable seat 5 is recessed, and a nut is installed on the bottom surface of the movable seat 5; at the same time, a double-acting screw is threaded onto the front and rear nuts, and the end of the double-acting screw is powered to a motor. The motor drives the double-acting screw to rotate, causing the front and rear movable seats 5 to move towards each other or away from each other at the same time, thus forming the longitudinal movement drive assembly 2.

[0044] In this embodiment, a plane is formed on the outer wall of the nut that fits against the bottom surface of the movable seat 5. Combined with the locking of the fastener, the fixation between the movable seat 5 and the nut is effectively guaranteed, especially preventing the nut from rotating.

[0045] In this embodiment, the bidirectional lead screw can also be two lead screws that are dynamically connected in the middle by an elastic coupling.

[0046] In this embodiment, an electromagnetic brake can be installed in conjunction with the motor drive component 2 to activate the electromagnetic brake and lock the rotation of the lead screw in the event of a sudden power failure of the motor.

[0047] After the lateral locking mechanism 3 unlocks the lateral lock, the motor in the longitudinal movement drive assembly 2 works, the bidirectional lead screw rotates, and in conjunction with the helical pair with the nut, it drives the two moving seats 5 to move in opposite directions, so that the wedge baffles 4 move away from the tires, releasing the fixation on the vehicle tires and effectively helping to get out of trouble quickly.

[0048] like Figure 4 As shown, the wedge-shaped baffle 4 is configured as an upwardly outward flared slope facing the side of the tire, and the left and right edges of the slope extend upward to form convex ribs 41, which are located on both sides of the tire.

[0049] After the vehicle stops, the wedge baffle 4 moves laterally along the movable seat 5, and the movable seat 5 moves longitudinally along the support beam 1 until the two movable seats 5 are moved to the front and rear of the vehicle tires respectively, and the inclined part of the wedge baffle 4 is directly attached to the tire; combined with the convex ribs 41 located on both sides of the tire, it effectively ensures reliable fixation.

[0050] The top surface of the movable seat 5 and the bottom surface of the wedge-shaped baffle 4 are fitted together to form a transverse moving structure.

[0051] In this embodiment, a groove can be provided on the bottom surface of the wedge-shaped baffle 4, and a protrusion that extends laterally on the top surface of the movable seat 5 can be fitted with a relatively movable groove, thereby realizing the relative movement of the wedge-shaped baffle 4 on the movable seat 5 in the lateral direction.

[0052] In this embodiment, the lateral movement of the wedge-shaped baffle 4 along the movable seat 5 can be driven by a power component such as a cylinder, or it can be manually pushed.

[0053] A smoke detector 10 is also installed on the support platform 7, which monitors the site conditions in real time and provides timely feedback.

[0054] like Figure 5 As shown, the strap assembly 9 includes two sets arranged from the vehicle tow hook toward the two tension posts 8; the structure of a single strap assembly 9 is as follows: it includes a movable strap 91, the fixed end of which is attached to the tow hook, and the movable end of which is wrapped around a ratchet tensioner 92, which adjusts the length of the movable strap 91 and tightens it; it also includes a fixed strap 93, one end of which is attached to the locking hook 86 via a hook 94, and the other end of which is fitted with a ratchet tensioner 92.

[0055] The strap assembly 9, located between the vehicle and the tension pile 8, can effectively ensure the reliable fixation of the front of the vehicle after being tightened by the ratchet tightener 92, especially preventing the vehicle from swaying left and right, thus facilitating the bench test.

[0056] In this embodiment, the ratchet tightener 92 is an existing standard product purchased externally. After the length of the movable strap 91 is adjusted, the ratchet tightener 92 tightens the movable strap 91 to fix its length.

[0057] like Figure 6 As shown, the structure of the tension pile 8 is as follows: it includes a pile body 81, a sliding support 83 installed inside the pile body 81 via a vertical guide rail 82, the sliding support 83 is adjusted in height along the vertical guide rail 82 and then locked and fixed; a cylinder with its output end arranged vertically downward is installed inside the sliding support 83, a moving block 84 is installed at the output end of the cylinder, a locking hook 86 is installed laterally on the moving block 84, the locking hook 86 passes outward through the sliding support 83 and the pile body 81 and then bends downward; a support platform 85 extends laterally from the bottom surface of the sliding support 83, the moving block 84 moves and drives the locking hook 86 to move downward until the outer end of the locking hook 86 abuts and fits against the support platform 85.

[0058] When the movable block 84 in the tension pile 8 moves downward and abuts against the support 85, the movable block 84 and the support 85 work together to fix the hook 94 in the strap assembly 9. After the movable block 84 moves in the opposite direction and disengages from the support 85, the hook 94 in the strap assembly 9 is released from its lock and can freely disengage from the support 85 and the tension pile 8, thus realizing automatic and quick unlocking of the front of the vehicle.

[0059] In this embodiment, as Figure 7 As shown, a control network can be deployed in conjunction with an automatic escape device, including but not limited to a safety layer, feedback layer, perception layer, and decision layer. The smoke alarm 10 is deployed in the perception layer for real-time monitoring. It can also be combined with other perception and monitoring methods to transmit information to the decision layer after a change in the perceived state, using methods such as buzzers and displays to alert personnel and require confirmation. If a fire is confirmed and the vehicle needs to be removed from the platform, an escape command can be issued remotely to automatically remove the vehicle from the platform.

[0060] The method for escaping entrapment using the automatic escaping device with drum platform locking in this embodiment includes the following steps:

[0061] During normal bench testing, the front two tires of the vehicle are located on the drum assembly 6, the rear two tires are limited by the wedge baffle 4, the lateral locking mechanism 3 is laterally locked, and the front of the vehicle is tightened and locked to the tension pile 8 by the strap assembly 9.

[0062] When it is necessary to unlock and escape, an escape command is sent to the drum assembly 6, the tension pile 8, the longitudinal movement drive assembly 2, and the lateral locking mechanism 3, and the drum assembly 6 stops working.

[0063] Upon receiving the extrication command, the lateral locking mechanism 3 unlocks the locking of the movable seat 5, and the longitudinal movement drive assembly 2 operates, driving the wedge baffle 4 to move along the longitudinal direction of the vehicle away from the tire along with the movable seat 5. Specifically, the cylinder in the lateral locking mechanism 3 reverses its action, causing the T-shaped part 31 to move away from the side of the T-shaped channel 11 and releasing the lateral abutment lock, allowing the movable seat 5 to move along the support beam 1. The motor in the longitudinal movement drive assembly 2 operates, driving the two movable seats 5 to move in opposite directions via the lead screw and nut, causing the wedge baffle 4 to move away from the tire, thereby releasing the fixation of the vehicle tire.

[0064] Upon receiving the escape command, the locking hook 86 in the tension pile 8 moves away from the end of the strap assembly 9, unlocking the strap assembly 9.

[0065] The vehicle can automatically escape from a locked state on the drum platform.

[0066] In this embodiment, when the escape command is executed, the drum assembly 6 first stops working, then the lateral locking mechanism 3 releases the lateral lock, the longitudinal movement drive assembly 2 drives the wedge baffle 4 away from the tire, and finally the locking hook 86 in the pull pile 8 is unlocked to lock the strap assembly 9. By setting the escape sequence, damage to the vehicle is effectively avoided when the tension of the strap assembly 9 is released during unlocking.

[0067] After the vehicle is automatically freed from the test bench, it can be quickly removed from the test bench by a forklift; of course, in actual operation, conventional methods such as winches can also be used to remove the vehicle from the test bench.

[0068] This invention enables remote control for the rapid unlocking of vehicles on a test bench without requiring personnel to approach the vehicle for manual unlocking, greatly facilitating the rapid and safe separation of vehicles from the test bench and ensuring personnel safety.

[0069] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
