Detailed description of the invention
As shown in Figures 1 to 6, a kind of impact breaker, the upper spider 2 comprising lower bearing bracket 1 and be arranged on lower bearing bracket 1, the inside top of upper spider 2 is provided with impact rack, impact rack is provided with hanger, front jointed shaft and rear jointed shaft are also installed, upper spider 2 above impact rack leaves lifting mouth, the width of lifting mouth is greater than the width of impact rack, the length of lifting mouth is greater than the distance that impact rack goes forward between jointed shaft and rear jointed shaft, impact rack can be taken out in lifting mouth, lifting mouth is also provided with observation door, to observe on top that door hinge is connected on upper spider 2 and to cover on lifting mouth, keep the sealing of upper spider, do not have material therefrom to dish out, the top of described upper spider 2 is also connected with adjusting device, the top of what adjusting device ran through be arranged on upper spider 2, the rear jointed shaft of impact rack is connected to the end of adjusting device, the end of adjusting device is provided with hinged groove 11 matching used with the rear jointed shaft of impact rack, hinged groove 11 is provided with dismountable cover plate, cover plate and arc bent plate 12 are with the use of the end making the rear jointed shaft of impact rack be fixed on adjusting device, the end of adjusting device is also provided with fixture, one end of fixture is connected to the end of adjusting device, the other end of fixture is connected on upper spider 2, this place's upper spider is connected with the mounting ear being connected and fixed device, the other end of fixture is arranged in mounting ear, the upper spider 2 of the front jointed shaft of corresponding impact rack is connected with L shape hook, L shape hook is connected with supporting dismountable briquetting 13, briquetting 13 covers on L shape hook, the medial surface of briquetting 13 and L shape hook is arc, briquetting 13 and L shape hook are fixed on upper spider 2 with the use of jointed shaft before making impact rack.
Further, described impact rack is 2, comprise the first impact rack 3 and the second impact rack 4, first impact rack 3 and the second impact rack 4 are arranged in order installation from top to bottom in the inside top of upper spider 2, the first lifting mouth 14 is left at upper spider top above first impact rack 3, the width of the first lifting mouth 14 is greater than the width of the first impact rack 3, first lifting mouth 14 is covered with the first observation door 7, upper spider above second impact rack 4 leaves the second lifting mouth 15, the width of the second lifting mouth 15 is greater than the width of the second impact rack 4, second lifting mouth 15 is covered with the second observation door 8, the front jointed shaft of the first impact rack 3 and the second impact rack 4 is installed in the L shape hook of upper spider 2, adjusting device comprises the first adjusting device 5 and the second adjusting device 6, and the position of the first adjusting device 5 and the second adjusting device 6 corresponding first impact rack 3 of difference and the second impact rack 4 is installed, first adjusting device 5 and the second adjusting device 6 are equipped with hinged groove 11 and arc bent plate 12, the rear jointed shaft of the first impact rack 3 is arranged in the hinged groove of the first adjusting device 5, the rear jointed shaft of the second impact rack 4 is arranged in the hinged groove of the second adjusting device 6, first adjusting device 5 is provided with the first fixture 9, second adjusting device 6 is provided with the second fixture 10,
During concrete enforcement, as shown in Figure 2, when dismounting or replacing impact rack, first, open the first observation door and second respectively and observe door, because the width lifting by crane mouth is greater than the width of impact rack, length is greater than the distance that impact rack is gone forward between jointed shaft and rear jointed shaft, unclamp the first impact rack, briquetting between second impact rack and upper spider, use outside boom hoisting and catch on the first impact rack, after the hanger at the second impact rack back, the first impact rack and the second impact rack can be made very easily respectively around the first adjusting device, upper spider can not be encountered to inner rotary in second adjusting device hinged place, in lifting process, due to the weight of impact rack, first adjusting device and the second adjusting device can produce vibration by a small margin, impact rack can oppress adjusting device, and the first fixture that the first adjusting device and the second adjusting device are arranged and the second fixture just serve the effect of buffering amplitude, also serve the effect of sharing impact rack weight simultaneously, make adjusting device can not be damaged, then, unclamp the arc bent plate in the first adjusting device and the second adjusting device again, the first impact rack and the second impact rack is made to depart from the first adjusting device and the second adjusting device respectively, thus the first impact rack and the second impact rack are lifted by crane away, be put into correct position to keep in repair or change impaired parts.
The method of traditional maintenance impact breaker is by upper lower bearing bracket separately, or separates at an angle by upper spider and lower bearing bracket, waste time and energy so on the one hand, and separately angle is very little, needs people to enter maintenance in body, so very dangerous; Impact rack entirety directly can be hung out impact crushing cavity by the present invention, service worker is when considering narrow space, find the unfavorable factors such as auxiliary equipment, very fast, counterpunch board and other consumable accessorys is changed easily, reduce maintenance time, reduce maintenance difficulties, enhance productivity.
