Description

Technical Field

[0001] This utility model belongs to the technical field of special equipment, specifically relating to a synchronous belt pressing device. Background Technology

[0002] To achieve "vertical access" parking, specialized parking equipment designed for ultra-high-rise scenarios is essential, and this equipment must meet two core requirements. First, stable and high-speed lifting performance: This requires balancing lifting efficiency with vehicle protection—the lifting speed must match the demands of ultra-high-rise vertical transportation to avoid prolonged waiting times for users; simultaneously, operational stability must be strictly controlled to prevent damage to the vehicle's paint, chassis, and internal precision components (such as electronic control and suspension systems). Second, ultimate fall protection: In ultra-high-rise scenarios, the consequences of a vehicle falling from dozens of stories are unimaginable. Therefore, the equipment must possess reliable fall risk avoidance capabilities, triggering protection mechanisms immediately in the event of critical component failure to prevent accidents.

[0003] However, most parking equipment currently on the market still has significant shortcomings in core safety protection, especially regarding critical failure modes such as rope and chain breakage, which directly lead to the risk of a fall. Real-time, reliable detection devices are generally lacking. Existing detection solutions mostly rely on two traditional methods: one is mechanical limit switches, which are prone to decreased accuracy due to wear, corrosion, and dust accumulation over long-term operation, and may even experience jamming, false alarms, or missed alarms; the other is manual periodic inspections, which not only have problems with long inspection cycles (usually weekly or monthly) and limited coverage, but are also susceptible to human error due to differences in the experience and lack of responsibility of the inspectors. Neither of these methods can capture early fault signals of rope or chain breakage in real time. If rope or chain breakage occurs outside of inspection periods, it can lead to sudden equipment shutdown and vehicle congestion, affecting normal user operation; in severe cases, it can cause serious safety accidents such as vehicle falls, posing a serious threat to the safety of users' property and even the safety of people in the residential common areas. Therefore, developing and applying reliable real-time detection devices for rope and chain breakage has become a crucial issue that urgently needs to be addressed to solve the safety problems of parking equipment in ultra-high-rise luxury residential buildings. Summary of the Invention

The system is equipped with a new type of pressing device that integrates pressing and belt breakage detection.

It ensures reliable operation of the synchronous toothed belt by pressing it firmly, and when a belt breakage occurs, it triggers the detection device, automatically stopping the system to guarantee equipment and personnel safety.

Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0025] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0026] Please see Figure 1 This embodiment provides a synchronous belt pressing device, including a pressing bracket 171, a locking pressing device 172, a limiting screw 173, a rotating shaft assembly 174, a rolling pressing wheel assembly 175, a rolling pressing wheel mounting plate 176, a limit switch 177, and a mounting bolt assembly 178. The pressing bracket 171 includes a bracket, an upper mounting plate, and a lower mounting plate. The locking pressing device 172 includes a main shaft, a handle, and an adjusting rod. The upper mounting plate, the lower mounting plate, and the rolling pressing wheel mounting plate 176 are all provided with a plurality of mounting holes. The rolling pressing wheel mounting plate 176 is connected to the upper mounting plate by the rotating shaft assembly 174. The limiting screw 173 is mounted on the upper mounting plate to limit the rotation of the rolling pressure roller assembly 175 and the rolling pressure roller mounting plate 176. The rotation is an upward rotation about the rotating shaft assembly 174. The rolling pressure roller assembly 175 is bolted to the rolling pressure roller mounting plate 176. The limit switch 177 is mounted on the lower mounting plate by the mounting bolt assembly 178. The adjusting rod is mounted on the main shaft. The top of the adjusting rod has a handle. According to the actual pressing requirements of the synchronous toothed belt, one end is adjusted to the correct position and then locked with a nut. The other end is locked and fixed to the pressure bracket 171.

[0027] Specifically, the support is formed by bending sheet metal into shapes such as bow, I-beam, arch, or other high-modulus shapes. The sheet metal is a composite structure, consisting of at least two layers of lightweight and high-strength materials, such as alloys or carbon fibers.

[0028] Specifically, the rotating shaft assembly 174 includes an outer cylinder, a spring-loaded assembly, and a limiting member, wherein there are two sets of limiting members; the spring-loaded assembly is fitted into the outer cylinder after a certain deformation, the first set of limiting members fixes the spring-loaded assembly, and the second set of limiting members limits the rolling pressure roller assembly 175.

[0029] Specifically, the locking and pressing device 172 consists of a round shaft 172-1 with two threaded mounting holes and two adjusting rods 172-2, one end of which has a ball handle 172-3 and the other end has a thread. The adjusting rods are mounted on the round shaft 172-1, and after adjusting the position according to the actual pressing requirements of the synchronous toothed belt, they are locked with nuts. The other end is locked and fixed to the pressing bracket 171.

[0030] It is worth explaining that the principle of the locking belt pressing device 172 is as follows: the locking belt pressing device 172, together with the rolling belt pressing wheel assembly 175, provides double belt pressing protection, achieving reliable pressing of the synchronous toothed belt, such as... Figure 3 As shown in the left figure, when the synchronous toothed belt is working normally, the rolling pressure pulley assembly 175 and the rolling pressure pulley mounting plate 176 need to be placed upwards on the synchronous toothed belt. Due to the upward pressure of the synchronous pulley and the downward pressure of the limiting screw 173, the rolling pressure pulley assembly is limited in typical working condition 1, and the pressure device is locked. As an auxiliary device, it can assist the rolling pressure pulley assembly in pressing the synchronous belt. When the synchronous toothed belt breaks, as shown in the right figure (typical working condition 2), because the two ends of the synchronous toothed belt are connected to the elevator and the counterweight system respectively, under the action of gravity, it will break. It will quickly fall down with the elevator and counterweight system. When the synchronous toothed belt disengages from the synchronous gear, the rolling pressure pulley assembly 175 loses pressure. Due to the influence of gravity and inertia, the rolling pressure pulley assembly 175 and the rolling pressure pulley mounting plate 176 will rotate downward around the rotating shaft assembly 174 and trigger the limit switch 177. The limit switch is pressed and sends a signal to the control system. The control system immediately executes the motor brake and fall protection device or safety clamp activation command to stop the system, thereby realizing the functions of synchronous toothed belt pressing and synchronous toothed belt breakage detection.

[0031] In particular, such as Figure 4 As shown, the rolling pressure roller assembly includes a main shaft, a fixing component, and several rolling pressure rollers. The rolling pressure rollers are equipped with bearings, and the rolling pressure rollers are connected in series by the main shaft through the bearings. The limiting component limits the rolling pressure rollers.

[0032] Specifically, the limit switch 177 is vertically positioned with the control head facing upwards.

[0033] It can be explained here that no matter how the limit switch 177 is fixed, as long as the limit switch 177 is initially in an open circuit state, when classic working condition 2 occurs, the rolling pressure pulley group can contact the limit switch 177 and cause the limit switch 177 to change state, that is, to be closed, thereby controlling the motor to stop working.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
