Description

Technical Field

[0001] This utility model belongs to the technical field of dust prevention devices for shotcrete machine lead screws, specifically relating to a dust prevention device for shotcrete machine lead screws with an anti-falling structure. Background Technology

[0002] The dustproof device for the shotcrete machine's lead screw is a key component that protects the lead screw from dust and other contaminants. It plays a crucial role in extending the lead screw's service life, improving the shotcrete machine's efficiency, and ensuring equipment safety. As the core transmission component of the shotcrete machine, the lead screw's precision and performance directly affect the overall operation of the equipment. If dust, moisture, or other contaminants enter the lead screw, it can lead to accelerated wear, poor lubrication, and even jamming, thus affecting the normal operation of the equipment. Therefore, installing an effective dustproof device is essential.

[0003] However, this device has the following drawbacks: In use, existing dustproof devices are generally installed on the lead screw surface of the shotcrete machine using a sleeve connection to effectively protect it from dust. However, in practical applications, shotcrete machines often operate in complex and variable working environments, which may involve strong vibrations or significant impacts. Under such conditions, the sleeve connection between the dustproof device and the lead screw may face serious challenges, significantly increasing the risk of loosening or even detachment. This would not only render the dustproof function ineffective but could also interfere with the normal operation of the shotcrete machine and even lead to safety accidents. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof device for the lead screw of a shotcrete machine with an anti-fall-off structure. This addresses the problem that existing dustproof devices typically use a sleeve connection to install on the lead screw surface for effective dust protection. However, in practical applications, shotcrete machines often operate in complex and variable environments, which may involve strong vibrations or significant impacts. Under such conditions, the sleeve connection between the dustproof device and the lead screw may face serious challenges, significantly increasing the risk of loosening or even detachment. This not only negates the dustproof function but may also interfere with the normal operation of the shotcrete machine and even lead to safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof device for a shotcrete machine screw with an anti-fall structure, comprising: a dustproof cover body, with joints on both sides of the dustproof cover body, a fixed plate fixedly connected to the top of the joints, a first limiting ring abutting one side of the fixed plate, a screw at the longitudinal end of the first limiting ring, the screw being inserted into the side wall of the fixed plate, a nut being threadedly connected to the surface of the screw, a washer abutting the side wall of the nut and being fitted onto the surface of the screw, vertical plates at both ends of a second limiting ring being inserted into the side wall of the screw, a dustproof rubber sleeve being fitted to the front end of the second limiting ring, the rear end of the dustproof rubber sleeve being inserted into the inner wall of the joint, threaded blocks on both sides of the transverse end surface of the dustproof rubber sleeve, an adjusting rod being threadedly connected to the surface of the threaded blocks, and the side wall of the adjusting rod being transversely connected to the side walls of the first and second limiting rings.

[0007] In order to fix the nut and washer in the position of the limiting ring on the fixing plate, as a preferred embodiment of the dustproof device for shotcrete machine screw with anti-fall structure of this utility model, the fixing plate, the first limiting ring, the screw, the nut, the washer and the second limiting ring form a threaded connection structure.

[0008] In order to facilitate the fixing of the screw by utilizing the through groove on the surface of the second limiting ring, as a preferred embodiment of the dustproof device for the shotcrete machine screw with anti-fall structure of this utility model, the two ends of the opening of the second limiting ring are provided with vertical plates, and the side wall of the vertical plates is provided with circular through grooves that are adapted to the screw.

[0009] In order to ensure that the threaded block and the adjusting rod cooperate to fix the position of the dustproof rubber sleeve, as a preferred embodiment of the dustproof device for shotcrete machine screws with an anti-fall structure of this utility model, the dustproof rubber sleeve, the threaded block and the adjusting rod form a threaded connection structure.

[0010] In order to allow the adjusting rod to pass through the two limiting rings to fix the position of the dustproof rubber sleeve, as a preferred embodiment of the dustproof device for the shotcrete machine screw with an anti-fall structure of this utility model, circular through grooves are respectively opened on both sides of the first limiting ring and the second limiting ring, and the shape and size of the through grooves are adapted to the adjusting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The cooperation between the fixing plate, the first limiting ring, the screw, the nut, the washer and the second limiting ring allows the joints on both sides of the dust cover body to be clamped and fixed after being sleeved on the surface of the shotcrete machine screw, thereby preventing the dust cover body from falling off due to the vibration generated during the operation of the shotcrete machine screw.

[0013] The first limiting ring, the second limiting ring, the dustproof rubber sleeve, the threaded block and the adjusting rod work together to wrap and protect the joints on both sides of the dust cover body and the connection of the shotcrete machine screw, so as to prevent dust from entering and affecting the operation of the shotcrete machine screw.

The side wall of the screw 5 is inserted into the vertical plates at both ends of the second limiting ring 8. The front end of the second limiting ring 8 is sleeved with a dustproof rubber sleeve 9. The rear end of the dustproof rubber sleeve 9 is inserted into the inner wall of the connector 2. The two sides of the transverse end surface of the dustproof rubber sleeve 9 are respectively provided with threaded blocks 10. The surface of the threaded blocks 10 is threadedly connected to the adjusting rod 11. The side wall of the adjusting rod 11 is transversely connected to the side wall of the first limiting ring 4 and the second limiting ring 8.

[0025] Preferably, the upper and lower ends of the outer wall of the connector 2 are respectively provided with fixing plates 3, and the side wall of the fixing plate 3 is provided with a circular through groove, and the shape and size of the through groove are adapted to the screw 5.

[0026] In practical use, the fixing plates 3 provided at the upper and lower ends of the connector 2 are used to insert and fix the screw 5, so that the screw 5 can pass through the fixing plates 3 to connect the first limiting ring 4 and the second limiting ring 8.

[0027] Preferably, the fixed plate 3, the first limiting ring 4, the screw 5, the nut 6, the washer 7, and the second limiting ring 8 form a threaded connection structure.

[0028] In practical use, the screw 5 connected to the first limiting ring 4 passes through the fixing plate 3 and then the second limiting ring 8 is inserted on the other side.

At the same time, the dustproof rubber sleeve 9 is sleeved at the intersection of the connector 2 and the shotcrete machine screw. Then, the fixing plates 3 provided at the upper and lower ends of the connector 2 are used to insert and fix the screw 5, so that the first limiting ring 4 connected to the other side of the screw 5 can be sleeved on the surface of the connector 2. Then, the through grooves opened on the upper and lower vertical plates of the second limiting ring 8 are sleeved on the surface of the screw 5, so that the first limiting ring 4 and the second limiting ring 8 can be sleeved on the surface of the connector 2. Then, the nut 6 is used to rotate the screw 5 towards the first limiting ring 4, so that its front end abuts against the first limiting ring 4. The washer 7 and nut 6 work together to fix the position of the first limiting ring 4 and the second limiting ring 8 on the fixing plate 3, thereby fixing the position of the dust cover body 1 on the surface of the shotcrete machine screw. At the same time, after the dustproof rubber sleeve 9, which is sleeved on the shotcrete machine screw, is put on the front end of the first limiting ring 4 and the second limiting ring 8, two adjusting rods 11 are used to pass through the through grooves on the surface of the first limiting ring 4 and the second limiting ring 8 respectively, and then fixed on the threaded blocks 10 on both sides of the dustproof rubber sleeve 9, thereby fixing the position of the dustproof rubber sleeve 9 on the joint 2.
