Description

Technical Field

[0001] The utility model relates to the technical field of backstops, in particular to a backstop with a coupling function. Background Art

[0002] Backstops, devices designed to prevent backflow of media, are widely used in various conveying systems, lifting equipment, and power transmission systems. In industrial production processes, various factors, such as power outages and equipment failures, can cause backflow within the conveying system, leading to equipment damage, production accidents, and even environmental pollution. To address this issue, the use of backstops is crucial.

[0003] In traditional mechanical equipment, backstops are typically used to prevent movement in a specific direction, while couplings are used to connect two or more rotating components to transmit torque. However, in some applications, installing a backstop on the output shaft side of a drive pulley can be difficult due to space constraints or other reasons.

[0004] Therefore, those skilled in the art provide a backstop with a coupling function to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the prior art and to propose a backstop with a coupling function. This structure combines the backstop with the coupling and installs it between the output end of the reducer and the input shaft of the transmission drum, thereby effectively solving the problem of insufficient space that the traditional backstop may face when installed on the output shaft side of the transmission drum. This design not only optimizes space utilization, but also ensures the effective implementation of the backstop function, thereby improving the reliability of the structure.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A backstop with a coupling function comprises a wheel hub and an intermediate wheel hub, wherein pins are evenly spaced apart on the outside of the wheel hub and the intermediate wheel hub, and an outer sleeve is provided on the outside of the wheel hub and the intermediate wheel hub, and connecting bolts are evenly spaced apart on the inside of the intermediate wheel hub, wherein one end of each connecting bolt passes through the intermediate wheel hub and is threadedly connected to the backstop body;

[0008] Through the above technical solution, the structure effectively solves the problem of insufficient space that may be faced when the traditional backstop is installed on the output shaft side of the transmission drum by combining the backstop with the coupling and installing it between the output end of the reducer and the input shaft of the transmission drum. This design not only optimizes space utilization, but also ensures the effective implementation of the backstop function, thereby improving the reliability of the structure.

[0009] Furthermore, the hub and the intermediate hub are provided with external teeth at even intervals on the outside, the outer sleeve is provided with internal teeth at even intervals on the inside, and the plurality of pins are located between the external teeth and the internal teeth;

[0010] Through the above technical solution, through the cooperation of external teeth and internal teeth and the setting of pins, precise engagement of gear transmission is achieved, effectively improving the transmission efficiency and stability of the coupling.

[0011] Furthermore, a baffle is threadedly connected to one side of the outer sleeve via a plurality of bolts, and the baffle is sleeved on the outside of the wheel hub;

[0012] Through the above technical solution, the connection strength between the hub and the outer sleeve is enhanced by bolt connection and the installation of baffles, while the axial movement of the pin is effectively prevented, ensuring the structural stability and durability of the coupling during operation.

[0013] Furthermore, the coupling is composed of a hub and a baffle, a pin, an outer sleeve, and an intermediate hub;

[0014] Through the above technical solution, the coupling rationally combines various components, ensures the coordinated operation between the various components, and improves the working efficiency and reliability of the overall transmission system.

[0015] Furthermore, a transmission roller is provided at one end of the backstop body, the end of the transmission roller close to the backstop body is the input end, and the end away from the backstop body is the output end;

[0016] Through the above technical solution, by setting up a transmission roller and rationally arranging the positions of its input and output ends, the transmission path and effect of the backstop are optimized, and the working efficiency and safety of the backstop are improved.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model proposes a backstop with a coupling function. When in use, this structure is connected to the motor through one end of the coupling. When the motor is driven normally, the coupling effectively transmits power from the output shaft end of the reducer to the transmission roller, pushing the equipment to operate in a predetermined direction. In the event of a power outage or a fault causing a shutdown, the lifting gravity of the material may attempt to cause the equipment to rotate in the opposite direction. At this time, the inner ring of the backstop changes its rotation direction and automatically switches to a backstop state, preventing the equipment from reversing and protecting the system from damage. This design not only improves the reliability and durability of the structure, but also reduces production losses and safety risks caused by unexpected shutdowns.

[0019] 2. The utility model proposes a backstop with a coupling function. When in use, this structure combines the backstop with the coupling and installs it between the output end of the reducer and the input shaft of the transmission drum, effectively solving the problem of insufficient space that may be faced by the traditional backstop when installed on the output shaft side of the transmission drum. This design not only optimizes space utilization, but also ensures the effective implementation of the backstop function, thereby improving the reliability of the structure.

[0027] The following will be combined with the drawings in the specific embodiments of the present invention to clearly and completely describe the technical solutions in the specific embodiments of the present invention. Obviously, the specific embodiments described are only part of the specific embodiments of the present invention, not all of the specific embodiments. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-5The utility model provides a specific embodiment: a backstop with a coupling function, including a hub 1 and an intermediate hub 5, the outside of the hub 1 and the intermediate hub 5 are evenly spaced with pins 3, the outside of the hub 1 and the intermediate hub 5 is covered with a sleeve 4, the inside of the intermediate hub 5 is evenly spaced with connecting bolts 6, one end of the plurality of connecting bolts 6 passes through the intermediate hub 5 and is threadedly connected to the backstop body 7;

[0029] This structure effectively solves the problem of insufficient space that may be faced when a traditional backstop is installed on the output shaft side of the transmission drum 8 by combining the backstop with the coupling and installing it between the output end of the reducer and the input shaft of the transmission drum 8. This design not only optimizes space utilization, but also ensures the effective implementation of the backstop function, thereby improving the reliability of the structure.

[0030] The hub 1 and the intermediate hub 5 are both provided with external teeth at even intervals on the outside, and the inner teeth are provided with internal teeth at even intervals on the inside of the outer sleeve 4. A plurality of pins 3 are located between the external teeth and the inner teeth. Through the cooperation of the external teeth and the inner teeth and the setting of the pins 3, the precise engagement of the gear transmission is achieved, which effectively improves the transmission efficiency and stability of the coupling. One side of the outer sleeve 4 is threadedly connected with a baffle 2 through a plurality of bolts 9. The baffle 2 is sleeved on the outside of the hub 1. The connection of the bolts 9 and the sleeve of the baffle 2 enhance the connection strength between the hub 1 and the outer sleeve 4, and at the same time effectively prevents the axial movement of the pins 3, ensuring that the coupling is in working condition. In order to ensure the structural stability and durability, the coupling consists of a hub 1 and a baffle 2, a pin 3, a sleeve 4, and an intermediate hub 5. The coupling reasonably combines the various components to ensure the coordinated operation of the various components and improve the working efficiency and reliability of the overall transmission system. A transmission roller 8 is provided at one end of the check body 7. The end of the transmission roller 8 close to the check body 7 is the input end, and the end away from the check body 7 is the output end. By providing the transmission roller 8 and reasonably arranging the positions of its input and output ends, the transmission path and effect of the check are optimized, and the working efficiency and safety of the check are improved.

[0031] Working principle: When in use, the backstop with coupling function effectively transmits power by combining the backstop with the coupling and installing it between the output end of the reducer and the input shaft of the transmission drum 8. When the motor is driven normally, the coupling effectively transmits power from the output shaft end of the reducer to the transmission drum 8, pushing the equipment to run in the predetermined direction. In the event of a power outage or a fault causing a shutdown, the lifting gravity of the material may try to cause the equipment to rotate in the opposite direction. At this time, the inner ring of the backstop changes its direction of rotation and automatically switches to the backstop state, preventing the equipment from reversing and protecting the system from damage.

[0032] Finally, it should be noted that the above is only a preferred specific implementation method of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned specific implementation methods, those skilled in the art can still modify the technical solutions described in the aforementioned specific implementation methods or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
