DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model discloses a noise reduction and sound insulation device for a drilling rig used in engineering construction, comprising a mobile structure 1, a drilling structure 2 and an external power supply 3 are arranged on the top of the mobile structure 1, and a noise reduction and sound insulation structure 4 is arranged on the inner side of the mobile structure 1;

[0024] The mobile structure 1 includes a mobile base 101 , a universal wheel is arranged at the bottom of the mobile base 101 , and a push handle 102 is fixedly installed on the back side of the mobile base 101 .

[0025] The drilling structure 2 includes a driving frame 201 , a linear motor 202 is arranged on the inner side of the driving frame 201 , a lifting platform 203 is fixedly installed on the movable end of the linear motor 202 , a drilling device 204 is fixedly installed inside the lifting platform 203 , and a drill rod of the drilling device 204 passes through a ball sleeve 403 .

[0026] The noise reduction and sound insulation structure 4 includes a sound insulation cover 401 , a top cover 402 is fixedly installed on the top of the sound insulation cover 401 , a ball sleeve 403 is fixedly installed at the center of the top cover 402 , and a ground contact cover shell 405 is fixedly installed on the bottom of the sound insulation cover 401 .

[0027] By setting up a noise reduction and sound insulation structure 4, the ball sleeve 403 set at the top of the sound insulation cover 401 can be in sliding contact with the drill rod of the drilling device 204 included in the drilling structure 2, so that the drilling structure 2 and the sound insulation cover 401 form a movable connection, which makes the drilling structure 2 and the sound insulation cover 401 relatively independent, so that the sound insulation cover 401 can reduce noise and sound insulation for the drilling structure 2 without affecting the operation of the drilling structure 2, so that the device not only protects the hearing health of the workers on the construction site, but also can reduce the noise impact on the residents living normally around, thereby increasing the practicality of the device.

[0028] Specifically, an electric push rod 103 is fixedly installed at the bottom end of the movable base 101 , and a contact plate 104 is fixedly installed at the movable end of the electric push rod 103 . The contact plate 104 is located below the movable base 101 .

[0029] In this embodiment, the electric push rod 103 is started, so that the movable end of the electric push rod 103 drives the contact plate 104 to gradually descend. Since the descending height of the contact plate 104 is greater than the height of the universal wheel, the contact plate 104 can lift the movable base 101 off the ground, so that the contact plate 104 can lift the movable base 101 instead of the universal wheel, so that the movable base 101 is fixed in the current position.

[0030] Specifically, the soundproof cover 401 includes a sound wave isolation tube 406, a noise reduction layer 407 is arranged on the inner side of the sound wave isolation tube 406, the noise reduction layer 407 is a polyester fiber sound insulation layer, a sound absorption cavity 408 is opened between the sound wave isolation tube 406 and the noise reduction layer 407, and sound-absorbing cotton is arranged inside the sound absorption cavity 408.

[0031] In this embodiment, the working principle of the acoustic isolation cylinder 406 has been described in a rotary drilling rig noise reduction structure with patent publication number CN220185046U, and will not be repeated here.

[0032] When the drilling device 204 generates noise, the noise will be reflected back to the noise source by the noise reduction layer 407, thereby reducing the spread of noise to the outside, and the sound waves will be absorbed for a second time by the sound-absorbing cotton in the sound-absorbing cavity 408, and the sound wave isolation tube 406 will reduce the spread to the outside again. By reflecting sound waves and reducing sound wave energy, the noise undergoes three noise reduction processes when it is transmitted outward, so that the noise is absorbed as much as possible inside the soundproof cover 401, thereby reducing the impact on the external environment, which not only protects the hearing health of the construction site workers, but also reduces the noise impact on the residents living normally around.

[0033] Specifically, a sleeve ring 404 is fixedly sleeved on the outer side of the soundproof cover 401 , a plug-in slot 105 is provided on the inner side of the movable base 101 , and the sleeve ring 404 is movably plugged into the inner wall of the plug-in slot 105 .

[0034] In this embodiment, the sleeve ring 404 can be used to drive the sound insulation cover 401 to be connected with the plug-in slot 105 inside the mobile base 101, thereby facilitating the maintenance of the sound insulation cover 401 by the staff.

[0035] Specifically, a damping spring 409 is disposed inside the ground contact cover 405 , and a ground contact ring 410 is disposed at the movable end of the damping spring 409 .

[0036] In this embodiment, the automatic resilience of the damping spring 409 can drive the ground contact ring 410 to always be in contact with the ground, so that the ground contact cover 405 and the ground are in an elastic overlapping state.

[0037] When in use, the universal wheels of the mobile base 101 are first used to drive the mobile base 101 to move to a specified position through the push handle 102, and then the electric push rod 103 is started, so that the movable end of the electric push rod 103 drives the contact plate 104 to gradually descend. Since the descending height of the contact plate 104 is greater than the height of the universal wheels, the contact plate 104 can lift the mobile base 101 off the ground, so that the contact plate 104 can replace the universal wheels to lift the mobile base 101, so that the mobile base 101 is fixed at the current position;

[0038] Then, the linear motor 202 inside the driving frame 201 is started, so that the movable end of the linear motor 202 drives the lifting platform 203 to adjust the height, and then the drilling device 204 is started, so that the lifting platform 203 drives the drilling device 204 to start drilling holes on the ground;

[0039] During the descent of the drilling device 204, the rotating rod of the drilling device 204 will slide relatively inside the ball sleeve 403, so that the descent of the drilling device 204 will not affect the use of the soundproof cover 401;

[0040] When the drilling device 204 generates noise, the noise will be reflected back to the noise source by the noise reduction layer 407, thereby reducing the spread of noise to the outside, and the sound waves will be absorbed for a second time by the sound-absorbing cotton in the sound-absorbing cavity 408, and the sound wave isolation tube 406 will reduce the spread to the outside again. By reflecting sound waves and reducing sound wave energy, the noise undergoes three noise reduction processes when it is transmitted outward, so that the noise is absorbed as much as possible inside the soundproof cover 401, thereby reducing the impact on the external environment, which not only protects the hearing health of the construction site workers, but also reduces the noise impact on the residents living normally around.

[0041] To sum up, the noise reduction and sound insulation device for drilling rigs used in engineering construction, by setting up a noise reduction and sound insulation structure 4, utilizes the ball sleeve 403 set at the top of the sound insulation cover 401 to be able to slide in contact with the drill rod of the drilling rig device 204 included in the drilling structure 2, so that the drilling structure 2 and the sound insulation cover 401 form a movable connection, which promotes the relative independence between the drilling structure 2 and the sound insulation cover 401, so that the sound insulation cover 401 can reduce noise and sound insulation for the drilling structure 2 without affecting the operation of the drilling structure 2, so that the device not only protects the hearing health of the workers on the construction site, but also can reduce the noise impact on the residents living normally around, thereby increasing the practicality of the device.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
