DETAILED DESCRIPTION
[0023] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.
[0024] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.
[0025] The present invention is further described below in conjunction with the embodiments and drawings:
[0026] Embodiment 1: As shown in the attached Figure 1 , 2 As shown in Figure 3, the high-strength, high-frequency, high-efficiency and energy-saving rock hook includes a connecting seat, a vibrator 1, a hook head 2, a shock-absorbing assembly and a swinging seat. The left part of the connecting seat and the left part of the swinging seat are hingedly installed together, and a crescent-shaped hook head 2 with an opening facing left is fixed on the lower side of the left part of the swinging seat. At least one guide block 3 is fixedly installed on the upper side of the right part of the swinging seat at intervals in front and back, and a guide hole that passes through from top to bottom is provided on the upper side of the right part of the connecting seat corresponding to the position of each guide block 3. A mounting plate 4 fixedly installed with the guide block 3 is provided on the upper side of the right part of the connecting seat, and the vibrator 1 is fixedly installed on the upper side of the mounting plate 4. A shock-absorbing assembly is installed between the lower side of the connecting seat corresponding to the left position of the guide block 3 and the upper side of the swinging seat.
[0027] According to the requirements, the left part of the guide block 3 is located above the right part of the hook head 2, and the hook head 2 is an existing well-known technology, such as a rock hook. During use, the setting of the swing seat facilitates the installation of the hook head 2, and the guide block 3 is installed on the upper side of the right part of the swing seat. In this way, the lower end of the hook head 2 and the guide block 3 are mutually misaligned, that is, there is an eccentric distance between the lower end of the hook head 2 and the guide block 3. The vibration of the vibrator 1 acting on the guide block 3 during operation will increase, thereby increasing the force acting on the stratum when the hook head 2 is excavated. By setting a shock-absorbing component, on the one hand, it can avoid the collision between the swing seat and the connecting seat when they are close to each other, and extend the service life. On the other hand, it can increase the excavation effect of the hook head 2 on the stratum, and can be used for excavation of harder strata and crushing of rocks. The left part of the connecting seat and the left part of the swing seat are hingedly installed together, and a shock-absorbing component is installed between the lower side of the connecting seat corresponding to the left position of the guide block 3 and the upper side of the swing seat. In this way, the connection between the connecting seat and the swing seat is simplified, and the maintenance cost and the occurrence rate of failure can be reduced.
[0028] The above-mentioned high-strength, high-frequency, high-efficiency and energy-saving rock hook and excavator can be further optimized and / or improved according to actual needs:
[0029] Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown, the swing seat includes a sleeve 5, a pin 6 and a fixed plate 7. The left side of the fixed plate 7 is fixedly installed with the outer side of the upper part of the sleeve 5. The sleeve 5 is internally provided with a pin 6 installed with the left part of the connecting seat. Two guide blocks 3 are fixedly installed at intervals on the front and rear sides of the upper left side of the fixed plate 7. The shock absorbing assembly is installed between the upper side of the fixed plate 7 on the left side of the guide block 3 and the lower side of the connecting seat. The upper side of the hook head 2 is fixedly installed on the lower side of the left part of the fixed plate 7.
[0030] During use, such a configuration facilitates the manufacture and maintenance of the swing seat. By providing two guide blocks 3, the connection between the guide block 3 and the mounting plate 4 is facilitated. The contact area between the guide block 3 and the mounting plate 4 can also be ensured, which facilitates the vibrator 1 to transmit vibration to the hook head 2.
[0031] Embodiment 3: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown in Figure 3, the connecting seat includes an articulated ear 8, a connecting ear 9 and a connecting plate 10. Two articulated ears 8 are fixed at intervals on the front and rear sides of the lower left side of the connecting plate 10. The outer front end and the outer rear end of the pin shaft 6 are respectively installed in the articulated ears 8 at corresponding positions. Two connecting ears 9 are fixed at intervals on the upper left side of the connecting plate 10. Two connecting holes 11 that pass through the front and rear sides are arranged at intervals on the upper part of each connecting ear 9. A guide hole corresponding to the guide block 3 is arranged on the upper right side of the connecting plate 10. The shock absorbing assembly is installed between the upper left side of the fixing plate 7 and the lower left side of the connecting plate 10.
[0032] According to the requirements, each hinged ear 8 is provided with a through hole corresponding to the pin 6 on the front side, and the gap between the front and rear parts of each guide hole and the guide block 3 is 1 to 2 mm. During use, the hinged ear 8 is provided to facilitate the disassembly and assembly between the connecting plate 10 and the fixed plate 7, and also facilitates the manufacturing. The connecting ear 9 is provided to facilitate the connection between the connecting seat and the existing equipment, and also facilitates the lifting and transportation of the hook head 2. The two guide holes are provided to better constrain the guide block 3, prevent the inertia of the guide block 3 from causing the fixed plate 7 to swing back and forth, and improve the stability of the hook head 2 when working.
[0033] Embodiment 4: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown, the shock absorbing assembly includes a shock absorbing limit pad 13, and a plurality of mounting sleeves 12 are fixed at intervals along the circumferential direction on the upper left side of the fixed plate 7 corresponding to the position between the shaft sleeve 5 and the guide block 3, and each mounting sleeve 12 is installed with a shock absorbing limit pad 13 whose upper side abuts against the lower side of the connecting plate 10.
[0034] During use, by setting the mounting sleeve 12, the shock-absorbing limit pad 13 can be restrained to prevent the shock-absorbing limit pad 13 from falling off. By setting the shock-absorbing limit pad 13, the life of the vibrator 1 can be shortened due to the collision between the swing seat and the connecting seat during operation, and the collision between the mounting plate 4 and the connecting plate 10 can be avoided. At the same time, the vibration influence of the hook head 2 on the equipment through the swing seat and the connecting seat during operation can be reduced, thereby extending the service life.
[0035] Embodiment 5: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown, the shock absorbing assembly also includes a shock absorbing spring 16, and a plurality of lower mounting grooves 15 with openings facing upward are provided at intervals on the upper left side of the fixed plate 7 at the position between two adjacent mounting sleeves 12, and an upper mounting groove 14 with openings facing downward is provided on the lower side of the connecting plate 10 corresponding to the position of each lower mounting groove 15, and a shock absorbing spring 16 is installed in each upper mounting groove 14 and the lower mounting groove 15 at the corresponding position.
[0036] According to the requirements, the depth of the lower mounting groove 15 is 30 to 40 mm, and the depth of the upper mounting groove 14 is 10 to 20 mm. The natural length of the shock-absorbing spring 16 is 160 to 170 mm. Since the relative swing angle between the fixing plate 7 and the connecting plate 10 is small, the upper mounting groove 14 corresponds to the lower mounting groove 15. The shock-absorbing spring 16 is a high-carbon steel spring, which has the characteristics of low manufacturing cost and durability. During use, by arranging the shock-absorbing spring 16, it can not only play a buffering role on the fixed plate 7 and the connecting plate 10, thereby reducing the vibration effect of the vibrator 1 on the equipment assembled with the connecting plate 10 when the vibrator 1 is working, but also can increase the impact effect of the tip of the hook head 2 on the formation when the vibrator 1 is working, thereby improving the excavation efficiency of the hook head 2. Moreover, when used in combination with the shock-absorbing limit pad 13, the shock-absorbing limit pad 13 can also prevent the distance between the fixed plate 7 and the connecting plate 10 from being too small when the vibrator 1 is working, resulting in the shock-absorbing spring 16 being compressed and deformed too much and then failing. The shock-absorbing limit pad 13 can play a limiting role on the fixed plate 7 and the connecting plate 10 when the vibrator 1 is working, that is, the shock-absorbing limit pad 13 limits the fixed plate 7 and the connecting plate 10 before the shock-absorbing spring 16 is compressed to the maximum deformation, thereby preventing the fixed plate 7 and the connecting plate 10 from getting closer to each other and increasing the deformation of the shock-absorbing spring 16, thereby causing the shock-absorbing spring 16 to fail, thereby extending the service life of the shock-absorbing spring 16 and the device.
[0037] Embodiment 6: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, a plurality of ribs 17 fixed to the lower side of the fixing plate 7 are distributed at intervals along the circumferential direction on the outer side of the upper portion of the hook head 2 .
[0038] During use, such a configuration can improve the connection strength between the fixing plate 7 and the hook head 2, thereby preventing the hook head 2 from breaking at the connection with the fixing plate 7 during use, thereby shortening the failure time.
[0039] Embodiment 7: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, the vibrator 1 is a hydraulic vibrator. The vibrator 1 is a known hydraulic vibrator, and its model is VC60D. This model of hydraulic vibrator 1 has the characteristics of high compressive strength and strong synergy. Compared with traditional vibrators, the vibrator 1 does not have horizontal interference force, and the vertical direction is vibration synergy, which increases the force on the hook head 2, thereby improving the rock crushing efficiency.
[0040] Embodiment 8: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown, two oil filling holes communicating with each other are arranged at intervals on the front and rear sides of the left outer side of the sleeve 5 , and an oil filling nozzle 18 is fixedly installed on the outer side of the sleeve 5 corresponding to the position of each oil filling hole.
[0041] During use, through such an arrangement, grease is regularly injected between the inner side of the sleeve 5 and the outer side of the pin 6 through the grease nozzle 18, which can reduce the wear between the sleeve 5 and the pin 6 when the hook head 2 works at a high frequency and reduce maintenance costs.
[0042] Embodiment 9: As an optimization of the above embodiment, as shown in the attached Figure 1 , 2 As shown, each guide block 3 has at least one lower mounting hole with a lower end extending to the lower side of the fixing plate 7 at intervals in front and back on the upper left side and the upper right side, and an upper mounting hole penetrating from top to bottom is provided on the upper side of the mounting plate 4 corresponding to the position of each lower mounting hole, and a connecting bolt 19 is installed in each upper mounting hole, the lower end of which passes through the lower mounting hole at the corresponding position and is screwed with a nut 20, and at least one lower positioning groove is provided on the upper side of each guide block 3 at intervals in the left and right sides, and an upper positioning groove is provided on the lower side of the mounting plate 4 corresponding to the position of each lower positioning groove, and a positioning pin 21 with the lower end located in the lower positioning groove at the corresponding position is installed in each upper positioning groove.
[0043] During use, by setting the connecting bolts 19 and the nuts 20, it is convenient to disassemble and assemble the mounting plate 4 and the guide block 3. By setting the positioning pin 21, the stability between the vibrator 1 and the fixed plate 7 can be improved, and relative sliding between the mounting plate 4 and the guide block 3 can be avoided, so that the high-frequency vibration of the vibrator 1 acts on the hook head 2, thereby improving the rock crushing efficiency.
[0044] Embodiment 10: As shown in the attached Figure 1 , 3 As shown in , 4, the excavator includes an excavator body 22 and a high-strength, high-frequency, high-efficiency, energy-saving rock hook, the end of the boom 23 of the excavator body 22 and the left part of the connecting seat of the high-strength, high-frequency, high-efficiency, energy-saving rock hook are hinged together, and the end of the piston rod of the bucket hydraulic cylinder 24 of the excavator body 22 is hinged together with the connecting seat.
[0045] During use, such a setting facilitates the transportation and use of high-strength, high-frequency, high-efficiency and energy-saving rock hooks, and can be used to excavate strata of a certain hardness for a long time. It is easy to operate and has higher excavation efficiency.
[0046] The above excavator can be further optimized and / or improved according to actual needs:
[0047] Embodiment 11: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3As shown in FIG. 4 , a liquid inlet pipe 26 is fixedly connected between the outlet of the distribution valve 25 of the excavator body 22 and the liquid inlet of the vibrator 1, and a liquid outlet pipe 27 is fixedly connected between the inlet of the distribution valve 25 and the liquid outlet of the vibrator 1. A connecting rod mechanism is installed between the piston rod end of the bucket hydraulic cylinder 24 of the excavator body 22 and the bucket arm 23. The connecting rod mechanism includes a rocker 28, a connecting rod 29, a connecting arm 30, a first connecting pin 31 and a second connecting pin 32. The right end of the bucket arm 23 of the excavator body 22 and the first end of the connecting arm 30 are connected to the connecting rod 23 of the excavator body 22. The left part of the connecting ear 9 is hingedly mounted together by a first connecting pin 31 passing through the connecting hole 11 on the left, the second end of the connecting arm 30, the first end of the connecting rod 29 and the right part of the connecting ear 9 are hingedly mounted together by a second connecting pin 32 passing through the connecting hole 11 on the right, the second end of the connecting rod 29, the first end of the rocker arm 28 and the right end of the piston rod of the bucket hydraulic cylinder 24 of the excavator body 22 are hingedly mounted together, and the second end of the rocker arm 28 is hingedly mounted together with the right part of the bucket arm 23 of the excavator body 22.
[0048] During use, the frequency of the vibrator 1 can be adjusted by adjusting the flow of the hydraulic oil in the liquid inlet pipe 26 through the distribution valve 25 on the excavator body 22. Thus, the vibration frequency of the hook head 2 can be adjusted, so that strata with different hardness can be excavated, and the excavation efficiency can be improved. The rocker 28, the connecting rod 29, the connecting arm 30 and the bucket rod 23 form a four-link 29 mechanism. The swing of the connecting arm 30 is achieved by the extension and contraction of the piston rod of the bucket hydraulic cylinder 24, thereby achieving the reciprocating swing of the connecting ear 9 and the hook head 2, so that the working process of the hook head 2 is consistent with the working process of the bucket, and the operation difficulty of the hook head 2 is reduced.
[0049] The above technical features constitute the embodiments of the present utility model, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
