Abstract
Description
Technical Field
[0001] This utility model relates to the field of speed reducer technology, and in particular to an impact-resistant worm gear reducer. Background Technology
[0002] A worm gear reducer is a power transmission mechanism used to reduce speed and increase torque, and is widely used in modern machinery. The worm gear reducer plays a role in matching speeds and transmitting torque between the prime mover and the working machine or actuator.
[0003] Currently, many worm gear reducers used in construction environments are exposed to the open air during operation. This working environment makes them susceptible to impacts from falling rocks or other objects. However, worm gear reducers should not be subjected to excessive impacts during operation, as this can easily cause them to malfunction due to collisions. Utility Model Content
[0004] This utility model proposes a composite stainless steel pipe resistant to external impact, which solves the above-mentioned problems existing in the use of the prior art.
[0005] The technical solution of this utility model is implemented as follows: an impact-resistant worm gear reducer includes a base and a body fixedly mounted on the base. A first baffle and an arched second baffle are provided above the body. The first baffle is fixedly mounted on the base, and the second baffle is movably mounted above the first baffle. A vibration mechanism and a limiting mechanism are provided between the first baffle and the second baffle.
[0006] The present invention is further configured such that the second baffle is a corrugated plate.
[0007] The present invention is further configured such that: the vibration mechanism includes an elastic support member, the elastic support member is disposed between the first baffle and the second baffle and its lower end is fixedly connected to the first baffle.
[0008] The present invention is further configured such that: the limiting mechanism includes a limiting rod fixedly disposed on the first baffle, the limiting rod extends upward and penetrates the second baffle, and a limiting block is provided at the upper end of the limiting rod, the limiting block being used to abut against the upper end of the second baffle.
[0009] The present invention is further configured such that: a through groove is provided on the second baffle for the limiting rod to pass through, wherein the opening area of the through groove is larger than the diameter of the limiting rod but smaller than the diameter of the limiting block.
[0010] The present invention is further configured such that: a guide ramp is provided at the upper end of the base, and the guide ramp is raised in the middle and gradually slopes downward around the perimeter.
[0011] The present invention is further configured such that: a surrounding wall is provided around the base, and a sewage trough is provided on the side wall of the surrounding wall.
[0012] In summary, the beneficial effects of this utility model are as follows:
[0013] 1. With this structure, the second baffle can be used to prevent falling objects from directly impacting the worm gear reducer. At the same time, the second baffle is set in an arch shape so that when an object rolls off the second baffle, the second baffle can keep the object as far away from the worm gear reducer as possible.
[0014] 2. The second baffle adopts a corrugated plate structure, which can play a buffering role when it is impacted, and helps to protect the second baffle itself.
[0015] 3. The elastic support can cause the second baffle to vibrate continuously when it is impacted, which can prevent some large falling objects from getting stuck on the corrugated plate.
[0016] 4. The fence can hold some miscellaneous items so that they roll into the base when they fall, and the drainage ditch can prevent rainwater from accumulating on the base. Attached Figure Description

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Example:
[0024] like Figures 1 to 3 As shown, this utility model discloses an impact-resistant worm gear reducer, including a base 1 and a body 2 fixedly mounted on the base 1. A first baffle 31 and an arched second baffle 32 are provided above the body 2. The first baffle 31 is fixedly mounted on the base 1, and the second baffle 32 is a corrugated plate and is movably mounted above the first baffle 31. At the same time, a vibration mechanism and a limiting mechanism are provided between the first baffle 31 and the second baffle 32.
[0025] The vibration mechanism specifically includes an elastic support member 33, which is disposed between the first baffle 31 and the second baffle 32 and its lower end is fixedly connected to the first baffle 31.
[0026] The limiting mechanism specifically includes a limiting rod 34 fixedly mounted on the first baffle 31. The limiting rod 34 extends upward and penetrates the second baffle 32. A limiting block 35 is provided at the upper end of the limiting rod 34. The limiting block 35 is used to abut against the upper end of the second baffle 32. Correspondingly, a through groove 36 is provided on the second baffle 32 for the limiting rod 34 to pass through. In this structure, the opening area of the through groove 36 is larger than the diameter of the limiting rod 34 but smaller than the diameter of the limiting block 35.
[0027] Furthermore, a guide ramp 11 is provided at the upper end of the base 1. The guide ramp 11 is raised in the middle and gradually slopes downward around the perimeter. At the same time, a wall 12 is provided around the base 1, and a sewage trough 13 is provided on the side wall of the wall 12.
[0028] The working principle of the above structure is as follows: the second baffle 32 is used to prevent falling objects from directly impacting the body 2, and the enclosure 12 is used to prevent objects from rolling down from the high ground near the body 2 into the base 1. Both of these settings can protect the body 2. At the same time, the second baffle 32 is set as a corrugated plate, which can act as a buffer after falling objects hit the second baffle 32, which is beneficial to protect the second baffle 32 itself. The elastic support 33 can drive the second baffle 32 to vibrate continuously. After some larger falling objects get stuck on the second baffle 32, the vibration of the second baffle 32 can be transmitted to the falling objects, which can loosen the engagement between the falling objects and the second baffle 32, so that the falling objects can roll off the second baffle 32. In addition, when it rains, when rainwater washes onto the body 2 and the base 1, some dust accumulation can be washed away. At this time, this accumulation can flow away from the drain, which can both play a role in sewage discharge and prevent rainwater from accumulating on the base 1.
[0029] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
