Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction, and in particular relates to an environmentally friendly energy-absorbing device, a high-frequency hydraulic breaker, and a tunneling machine. Background Technology

[0002] The principle of a high-frequency hydraulic breaker is as follows: a hydraulic motor drives an eccentric block to rotate, generating excitation force. The vibration is transmitted to the hammer head through the vibrator housing. The vibrating hammer head does work on the object, thus achieving the purpose of breaking it. During operation, the working arm of the tunneling machine drives the high-frequency hydraulic breaker to perform excavation work. The working arm of the tunneling machine drives the hammer head of the high-frequency hydraulic breaker to always keep it pressed against the part to be broken. The impact force of the vibrator during operation impacts the part to be broken. The impact force of the vibrator comes from the centrifugal force generated when the eccentric block moves in a circular motion. When the eccentric block works, the direction of the centrifugal force it generates changes cyclically in the circumferential direction. The centrifugal force pointing forward is the effective impact force, while the centrifugal force pointing backward cannot be used for impact operation and needs to be buffered by an energy absorption device to avoid excessive vibration.

[0003] In existing technologies, energy-absorbing devices are usually implemented using structures such as airbags and springs. Although such energy-absorbing devices can achieve the function of energy absorption, the backward force exerted by the eccentric block of the vibrator on the hammer head also has strong kinetic energy. If this kinetic energy can be rationally utilized, it will be of great significance for saving energy and improving the efficiency of tunnel construction. Utility Model Content

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0025] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0026] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0027] Please see Figure 1-3 This utility model provides an environmentally friendly energy-absorbing device, comprising: a first mounting plate 1, a second mounting plate 2, a first energy-absorbing mechanism 3, and a second energy-absorbing mechanism 4; the first energy-absorbing mechanism 3 includes a water bladder 31, an inlet switch assembly 32, and an outlet switch assembly 33; one end of the water bladder 31 is connected to the first mounting plate 1, and the other end is connected to the second mounting plate 2, the inlet and outlet of the water bladder 31 are disposed on the second mounting plate 2, and the inlet switch assembly 32 and the outlet switch assembly 33 are disposed inside the water bladder 31. The second energy-absorbing mechanism 4 is installed inside the water bladder 31, with one end connected to the first mounting plate 1 and the other end connected to the second mounting plate 2. When the first energy-absorbing mechanism 3 and the second energy-absorbing mechanism 4 absorb energy, the water bladder 31 is compressed, the outlet switch assembly 33 opens the outlet, and the water inside the water bladder 31 flows out through the outlet. When the first energy-absorbing mechanism 3 and the second energy-absorbing mechanism 4 reset, the water bladder 31 is stretched, the inlet switch assembly 32 opens the inlet, and water enters the water bladder 31 through the inlet.

[0028] The second mounting plate 2 may be provided with two through holes, which correspond to the water inlet and the water outlet respectively, so as to facilitate the connection of the external water pipe to the water inlet and the water outlet. The water bladder 31 may be made of elastic materials such as rubber. Elastic materials such as rubber have good elasticity and flexibility, and can be repeatedly stretched and compressed in multiple reciprocating movements without permanent deformation or damage.

[0029] The inlet pipe can be connected to a water tank, and the outlet pipe can be connected to a nozzle installed on the corresponding equipment, the water flow inside the tunnel, or a pipe used to guide water out of the tunnel. This embodiment does not impose any limitations on this. In practical use, the first energy-absorbing mechanism 3 can be approximated as a water pump, utilizing the pressure acting on the energy-absorbing device and the restoring force of the second energy-absorbing mechanism 4 to achieve water intake and drainage, thereby guiding water flow or reducing dust in the construction area.

[0030] Please see Figure 1-4 Specifically, the inlet switch assembly 32 may include two first snap-fit ​​members 321, a first elastic member 322, a seal member 323, a trigger member 324, a sleeve 325, and a second elastic member 326. The sleeve 325 is a hollow cylindrical structure with one end open and the other end closed, and its open end is connected to the inlet. A first boss 3252 is provided inside the open end of the sleeve 325. Two oppositely arranged clearance openings 3251 are provided on the outer side of the sleeve 325, and the extension direction of the clearance openings 3251 is the same as the extension direction of the sleeve 325.

[0031] A sealing element 323 is disposed inside the sleeve 325 and is used to abut against the first boss 3252 to seal the open end of the sleeve 331. The first boss 3252 can be an annular structure protruding from the inner sidewall of the sleeve 325. The sealing element 323 has a disc structure and is used to abut against the first boss 3252, thereby sealing the open end of the sleeve 331. Two first engaging portions 3231 can be provided at intervals on the sealing element 323. The first engaging portions 3231, the clearance opening 3251, and the first engaging element 321 are provided in a one-to-one correspondence. The first engaging portion 3231 can be a strip-shaped structure, with one end connected to the outer sidewall of the sealing element 323 and the other end passing through the clearance opening 3251 and connecting to the first engaging element 321. The first elastic element 322 is disposed inside the sleeve 325, with one end connected to the closed end of the sleeve 325 and the other end connected to the sealing element 323, for maintaining the sealing of the open end of the sleeve 331 by the sealing element 323. In this embodiment, the first elastic element 322 is a spring. In other implementations, the first elastic element 322 may also be other structures, and this embodiment does not limit this.

[0032] Two first snap-fit ​​pieces 321 are spaced apart on the first mounting plate 1 and rotatably connected to it. Specifically, each first snap-fit ​​piece 321 may have a rotating shaft, and the first mounting plate 1 may have a mounting seat for connecting to the rotating shaft, thereby achieving the rotatable connection between the first snap-fit ​​piece 321 and the first mounting plate 1. At the end of each first snap-fit ​​piece 321 away from the first mounting plate 1, a second snap-fit ​​part 3211 is provided for connecting to the first snap-fit ​​part 3231. The second snap-fit ​​part 3211 may be a snap-fit ​​structure, used to hook the first snap-fit ​​part 3231 during use. Of course, the second snap-fit ​​part 3211 can also have other structural forms, which are not limited in this embodiment. The second snap-fit ​​part 3211 has a first inclined surface, and the first snap-fit ​​part 3231 has a second inclined surface, thereby facilitating the connection between the first snap-fit ​​part 3231 and the second snap-fit ​​part 3211.

[0033] The first latching member 321 is also provided with a trigger part 3212 for connecting with the trigger member 324. The trigger part 3212 can be a first inclined structure that is provided on one side opposite to the two first latching members 321 and protrudes from the first latching member 321. The inclined surface of the first inclined structure faces the first mounting plate 1. The first inclined structure and the first latching member 321 can be integrally formed, or they can be separately formed and then fixed to the first latching member 321 by screws or snap-fit.

[0034] The trigger element 324 can be fixedly installed on the second mounting plate 2 by a support column or other structure. In this embodiment, the trigger element 324 is disposed on the outer side of the third guide column 411 on the second mounting plate 2. There are two trigger elements 324, each corresponding to the trigger part 3212 of one of the first latching elements 321. The trigger element 324 is disposed between the two first latching elements 321. The side of the trigger element 324 opposite to the corresponding first latching element 321 is provided with a third inclined surface and a non-inclined surface. The non-inclined surface is disposed close to the first mounting plate 1, and the third inclined surface is disposed away from the first mounting plate 1. The third inclined surface gradually moves away from the corresponding first latching element 321 from the connection point with the non-inclined surface. The third inclined surface is used to abut against the trigger part 3212, that is, to abut against the aforementioned first inclined structure, so that the two first latching elements 321 rotate about the connection point of the first mounting plate 1, thereby disengaging the second latching part 3211 and the first latching part 3231.

[0035] One end of the second elastic member 326 is connected to one of the first latching members 321, and the other end is connected to the other first latching member 321. The second elastic member 326 is used to maintain the two first latching members 321 in a state where they can be latched with the first latching part 3231. The state where they can be latched with the first latching part 3231 is as follows: Figure 2The vertical state shown refers to the state where the extension direction of the first latching member 321 is parallel to the central axis of the third guide post 411. The second elastic member 326 can be a tension spring, a spring, or other elastic structures; however, this embodiment does not limit its use. In this embodiment, the second elastic member 326 is a tension spring, with each end connected to one of the first latching members 321. When the two first latching members 321 are in the vertical position... Figure 2 When the first engaging member 321 is in the engaging state, the tension spring is neither compressed nor stretched, thus maintaining this state. In one implementation, when the first engaging member 321 is in the engaging state, the non-tilted surface of the trigger member 324 abuts against the side of the corresponding first engaging member 321, preventing the two first engaging members 321 from rotating towards each other, thereby maintaining their vertical state. It can be understood that the second elastic member 326 also prevents the two second engaging members from rotating away from each other.

[0036] The working principle of the inlet switch assembly 32 is as follows: When the water bladder 31 is full of water, the first locking part 3231 and the second locking part 3211 are not connected. When the energy absorption device is subjected to external pressure, the water bladder 31 and the second energy absorption mechanism 4 are compressed. At this time, the outlet switch assembly 33 opens the outlet, allowing the water in the water bladder 31 to be discharged. As the external pressure of the energy absorption device continues to act, the first locking part 3231 and the second locking part 3211 engage.

[0037] When the external pressure on the energy-absorbing device is removed, the first energy-absorbing mechanism 3 and the second energy-absorbing mechanism 4 are reset. Under the action of the reset force of the second energy-absorbing mechanism 4, the first mounting plate 1 moves relative to the second mounting plate 2. That is, the second locking part 3211 of the first locking member 321 drives the first locking part 3231 to move. Due to the movement of the first locking part 3231, the sealing member 323 disengages from the first boss 3252, so that water can enter the water bag 31 through the water inlet and the clearance hole. At this time, the first elastic member 322 is compressed.

[0038] As the resetting force of the first energy-absorbing mechanism 3 and the second energy-absorbing mechanism 4 continues to act, the trigger 324 connects with the trigger part 3212. Specifically, the third inclined surface of the trigger 324 gradually contacts the first inclined structure. At this time, the first locking member 321 rotates around the connection point with the first mounting plate 1. Until the second locking part 3211 disengages from the first locking part 3231, the sealing member 323, under the action of the first elastic member 322, abuts against the first boss 3252, thereby closing the water inlet.

[0039] Please see Figure 3-4The closed end of the sleeve 325 is also provided with a first guide post 3253, which is a hollow columnar structure; a second guide post 3232 is provided on the sealing element 323, and the second guide post 3232 is slidably connected to the first guide post 3253; a first elastic element 322 is sleeved on the second guide post 3232, with one end connected to the sealing element 323 and the other end connected to the first guide post 3253. Specifically, the closed end of the sleeve 325 is provided with a sleeve 325 cap, the sleeve 325 is provided with internal threads, and the closed end of the sleeve 325 is provided with external threads. The sleeve 325 cap is connected to the sleeve 325 through the threads to close the closed end of the sleeve 325, thereby facilitating the placement of the sealing element inside the sleeve 325. A first guide post 3253 is provided inside the sleeve 325 cap. The first guide post 3253 has a cavity for accommodating a second guide post 3232, which is located at the end of the sealing member 323 away from the first boss 3252. The first elastic member 322 can be a structure with elasticity. The arrangement of the first elastic member 322, the first guide post 3253, and the second guide post 3232 guides the movement of the sealing member 323. A first sealing member 3254 is also provided inside the cavity of the first guide post 3253. In this embodiment, the first sealing member 3254 is an O-ring, which is fixedly installed inside the cavity of the first guide post 3253 to prevent water from entering the cavity and to avoid increased pressure inside the cavity due to water entering, which would restrict the forward movement of the sealing member 323.

[0040] Please see Figure 3 , 5 In one implementation, the outlet switch assembly 33 includes a sealing sleeve 331, a baffle 332, and a third elastic member 333. The sealing sleeve 331 is disposed inside the outlet of the second mounting plate 2. One end of the sealing sleeve 331 is provided with a second boss 3311, and the other end is provided with a third boss 3312. The baffle 332 and the third elastic member 333 are disposed inside the sealing sleeve 331. One end of the third elastic member 333 is connected to the third boss 3312, and the other end is connected to the baffle 332. The end of the baffle 332 away from the third elastic member 333 is used to abut against the second boss 3311.

[0041] Specifically, the baffle 332 is a circular baffle 332. The inner diameter of the inner ring of the second boss 3311 is smaller than the outer diameter of the baffle 332, and the inner diameter of the inner ring of the third boss 3312 is also smaller than the outer diameter of the baffle 332, thereby preventing the baffle 332 from sliding out of the sealing sleeve 331. The third elastic element 333 is an elastic structure. In this embodiment, the third elastic element 333 is a spring, which is used to reset the baffle 332 so that it abuts against the second boss 3311.

[0042] The working principle of the outlet switch assembly 33 is as follows: When the energy-absorbing device is subjected to external pressure, the pressure inside the water bladder 31 increases. Under the action of water pressure, the baffle 332 disengages from the second protrusion 3311, allowing water to flow out through the gap between the inner ring of the second protrusion 3311, the inner wall of the baffle 332 and the sealing sleeve 331, and the inner ring of the third protrusion 3312. When the water in the water bladder 31 has completely flowed out or the external pressure on the energy-absorbing device is removed, the baffle 332, under the action of the third elastic element 333, abuts against the second protrusion 3311, thereby sealing the outlet.

[0043] Please see Figure 1-4 6-7, The second energy-absorbing mechanism 4 includes a sealing component 41 and an energy-absorbing component. The energy-absorbing component is disposed inside the sealing component 41. The sealing component 41 is used to prevent water from entering the energy-absorbing component from the water bladder 31.

[0044] Specifically, the sealing assembly 41 includes a third guide post 411, a fourth guide post 412, and a second sealing element 413. The third guide post 411 is disposed on the second mounting plate 2 and is a hollow columnar structure. The fourth guide post 412 is disposed on the first mounting plate 1 and is also a hollow columnar structure, with its outer side wall slidably connected to the inner side wall of the third guide post 411. The second sealing element 413 is disposed on the inner side wall of the third guide post 411 and abuts against the outer side of the fourth guide post 412 to prevent water from entering the third guide post 411. The trigger element 324 can be fixed to the outer side of the third guide post 411 by screws. The third guide post 411 and the fourth guide post 412 guide the movement of the first mounting plate 1, preventing the water bag 31 from shifting position during movement. The third guide post 411 has a cavity for accommodating the fourth guide post 412. In this embodiment, the second seal 413 is an O-ring seal 323, which is fixedly disposed in the cavity of the third guide post 411 to prevent water from entering the cavity of the third guide post 411. This avoids the pressure inside the cavity increasing due to water entering the cavity, which would restrict the forward movement of the fourth guide post 412. In one implementation, the end of the fourth guide post 412 near the first mounting plate 1 is provided with a fourth inclined surface, which faces the first mounting plate 1 to reduce water resistance when the first mounting plate 1 moves towards the second mounting plate 2.

[0045] The energy-absorbing assembly includes a fifth guide post 421, a sixth guide post 422, a first sliding post 423, a second sliding post 424, a fourth elastic element 425, a fifth elastic element 426, and a sixth elastic element 427. The fifth guide post 421 is disposed within the third guide post 411, and one end of it is connected to the second mounting plate 2. The fifth guide post 421 is a hollow columnar structure. The fourth elastic element 425 and the first sliding post 423 are disposed within the fifth guide post 421. One end of the fourth elastic element 425 is connected to the second mounting plate 2. The plate 2 is connected at one end and the other end is connected to the first sliding post 423. The outer side of the first sliding post 423 may be provided with a plurality of first protrusions at intervals, and the inner side wall of the fifth guide post 421 may be provided with a plurality of first grooves 4211. The first grooves 4211 and the first protrusions are provided in a one-to-one correspondence. The extension direction of the first protrusions and the first grooves 4211 is the same as the extension direction of the fifth guide post 421, so as to guide the first sliding post 423 and prevent it from rotating relative to the fifth guide post 421.

[0046] The sixth guide post 422 is disposed inside the fourth guide post 412. The sixth guide post 422 is a hollow columnar structure. The sixth guide post 422 is connected to the first mounting plate 1, and the outer side wall of the sixth guide post 422 is slidably connected to the inner side wall of the fifth guide post 421. Multiple second protrusions 4221 may be provided on the outer side surface of the sixth guide post 422. The second protrusions 4221 are corresponding to the first sliding grooves 4211. The extension direction of the second protrusions 4221 is the same as the extension direction of the sixth guide post 422. The second protrusions 4221 and the first sliding grooves 4211 are used to guide the sixth guide post 422 and prevent the sixth guide post 422 from rotating relative to the fifth guide post 421.

[0047] The second sliding post 424 and the fifth elastic element 426 are disposed inside the sixth guide post 422. One end of the fifth elastic element 426 is connected to the first mounting plate 1, and the other end is connected to the second sliding post 424. Multiple third protrusions may be provided on the outer side wall of the second sliding post 424, and multiple second sliding grooves 4222 may be provided on the inner side wall of the sixth guide post 422. The third protrusions and the second sliding grooves 4222 are provided in a one-to-one correspondence. The extension direction of the third protrusions and the second sliding grooves 4222 is the same as the extension direction of the sixth guide post 422, so as to guide the second sliding post 424 and prevent it from rotating relative to the sixth guide post 422.

[0048] The sixth elastic element 427 is disposed inside the sixth guide post 422. One end of the sixth elastic element 427 is connected to the second sliding post 424, and the other end is connected to the first sliding post 423. The elastic coefficient of the sixth elastic element 427 is less than that of the fourth elastic element 425 and the fifth elastic element 426.

[0049] The fourth elastic element 425, the fifth elastic element 426, and the sixth elastic element 427 are elastic structures. In this embodiment, the fourth elastic element 425, the fifth elastic element 426, and the sixth elastic element 427 are springs, which are used to absorb the external forces acting on the energy-absorbing device, thereby achieving the energy-absorbing effect. The elastic coefficient of the sixth elastic element 427 is less than that of the fourth elastic element 425 and the fifth elastic element 426. In specific implementations, the elastic coefficients of the fourth elastic element 425 and the fifth elastic element 426 can be the same or different, as long as the elastic coefficients of the fourth elastic element 425 and the fifth elastic element 426 are greater than that of the sixth elastic element 427. In this embodiment, the fourth elastic element 425 and the fifth elastic element 426 have the same structure, that is, the same material, elastic coefficient, and length.

[0050] In use, because the elastic coefficient of the sixth elastic element 427 is smaller than that of the fifth elastic element 426 and the sixth elastic element 427, the sixth elastic element 427 is compressed first when the energy-absorbing device is subjected to external forces. At this time, the water in the water bladder 31 can quickly flow out through the outlet. As the external forces continue to act on the energy-absorbing device, the sixth elastic element 427, the fourth elastic element 425, and the fifth elastic element 426 are also compressed. This allows the three elements to absorb the external forces acting on the energy-absorbing device. It can be understood that the water bladder 31 also plays an energy-absorbing role during the backward movement of the hammer head 7.

[0051] Please see Figure 8 In another aspect, this utility model also provides a high-frequency hydraulic breaker, which includes an outer housing 5, a vibrator 6, and a hammer head 7, as well as the aforementioned environmentally friendly energy-absorbing device. The vibrator 6 is disposed inside the outer housing 5, and the hammer head 7 is disposed at the front end of the vibrator 6. One end of the energy-absorbing device is connected to the inner side wall of the outer housing 5, and the other end is connected to the rear end of the vibrator 6. Preferably, multiple nozzles are also provided near the hammer head 7 on the outer housing 5, and the multiple nozzles are connected to the water outlet of the energy-absorbing device, so that water can be sprayed onto the construction area of ​​the hammer head 7 using the water bladder 31 of the energy-absorbing device to achieve the effect of dust suppression.

[0052] In another aspect, this utility model also provides a tunneling machine, including a robotic arm and a high-frequency breaker as described above, the high-frequency breaker being mounted on the robotic arm.
