Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of expansion hammers, and more specifically, to an expansion hammer for filling a molten tank area. Background Art
[0002] In the construction of some bridge foundations, many of them are difficult to construct due to complex geological conditions and strong karst development on the site. There are many factors that affect the construction of bridge pile drivers. For bored piles and subsequent underwater concrete pouring, karst caves are undoubtedly the biggest challenge. If there are no technical countermeasures during construction, the quality and hole formation rate of bored piles will undoubtedly decline. Bored piles under karst geological conditions have more types of diseases and more complex and difficult coping technologies, such as leakage, buried drill, and stuck drill. Because diseases often occur in the drilling process and the geological conditions at the location are complex, it is necessary to first use an expansion hammer to drill and extrude the pile position to protect the wall, complete the cave crossing, and then proceed with subsequent construction.
[0003] In existing expansion hammers, most hammer heads are composed of narrow planes. When the expansion hammer falls downward due to gravity, it will come into contact with water. Due to the flat setting of the hammer head, the resistance encountered in the water will increase, so more energy will be lost, which reduces the efficiency of drilling and extrusion. Utility Model Content

[0010] As a preferred technical solution of the present invention, the sealing ring is annular and located outside the fixed plate. The height of the sealing ring is higher than that of the fixed plate, and the hammer body is conical as a whole.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] like Figures 1 to 5 As shown, the utility model provides an expansion hammer for filling a molten tank area, comprising a hammer body 1, a mounting hole 2 is opened at the bottom of the hammer body 1, a hammer head 3 is engaged inside the mounting hole 2, a striker 4 is fixedly installed at the bottom of the hammer head 3, connecting blocks 5 are fixedly installed on both sides of the hammer body 1, a stabilizing plate 6 is fixedly installed on the side of the connecting block 5 away from the central axis of the hammer body 1, there are multiple strikers 4, and the multiple strikers 4 are all vertebral.
[0022] The diameter of the mounting hole 2 is smaller than the diameter of the bottom of the hammer body 1. The main function of the multiple strikers 4 is that when the hammer body 1 is lifted and falls downward, the multiple strikers 4 will first contact the water surface. Therefore, since the pointed parts of the multiple strikers 4 are downward, after contacting the water surface, they will break the tension of the water. Therefore, when the hammer body 1 is carried as a whole and descends, the resistance with the water will be greatly reduced, thereby increasing the falling speed.
[0023] Among them, a fixing groove 7 is opened inside the hammer body 1, and a limiting bracket 8 is fixedly installed inside the fixing groove 7. A billiard ball 13 is provided inside the fixing groove 7, and a connecting plate 14 is fixedly installed above the billiard ball 13. A connecting shaft 15 is rotatably connected to the inside of the connecting plate 14, and a connecting sleeve 16 is sleeved on the outside of the connecting shaft 15.
[0024] The billiard ball 13 is cylindrical and can move up and down inside the fixed groove 7. When the hammer body 1 falls downward and hits the rock hole, the billiard ball 13 falls downward from the highest point of the fixed groove 7, causing the hammer body 1 to hit the rock hole for the second time, thereby increasing the efficiency of expansion and support on both sides.
[0025] Among them, a fixing plate 9 is fixedly installed above the hammer body 1, a motor 10 is fixedly installed on the outside of the fixing plate 9, a storing wheel 11 is fixedly installed on the output end of the motor 10, and a steel wire rope 12 is rotatably connected to the outside of the storing wheel 11. The end of the steel wire rope 12 away from the storing wheel 11 is fixedly connected to the connecting sleeve 16.
[0026] When it is necessary to lift the billiard ball 13, the motor 10 is started to drive the storage wheel 11 to rotate, so that the wire rope 12 is wound around the outside of the storage wheel 11. At the same time, the billiard ball 13 is driven to rise through the connection between the connecting sleeve 16 and the connecting shaft 15, and can be fixed under the limit bracket 8. When it is necessary to drop, the motor 10 is rotated rapidly in the opposite direction, so that the billiard ball 13 has the effect of free fall, thereby achieving the effect of making the hammer body 1 have a secondary impact.
[0027] A sealing ring 17 is fixedly installed above the hammer body 1, and a screw hole 18 is opened inside the sealing ring 17. A sealing plate 19 is provided above the sealing ring 17. A bolt 20 is meshed inside the sealing plate 19. The bolt 20 is meshed with the screw hole 18. A weight block 21 is fixedly installed above the sealing plate 19.
[0028] The sealing plate 19 seals the upper portion of the sealing ring 17 by engaging the bolt 20 with the screw hole 18 , thereby preventing water from entering the fixing groove 7 after water enters the interior of the sealing ring 17 .
[0029] Among them, a slide groove 22 is opened inside the weight-increasing block 21, and a slider 23 is slidably connected inside the slide groove 22. A lifting ear 24 is fixedly installed above the slider 23, and bolts 25 are engaged on both sides of the lifting ear 24. Bolts 25 are engaged with the weight-increasing block 21.
[0030] After the slider 23 carrying the lifting ear 24 is installed to the inside of the weight block 21 through the sliding action with the slide groove 22, the bolt 25 is used to fix the lifting ear 24, so as to achieve the effect of conveniently connecting and lifting the hammer body 1 as a whole through the lifting ear 24. At the same time, the lifting ear 24 can be removed in time by removing the bolt 25, thereby facilitating the recycling of the lifting ear 24 and eliminating the need for welding to prevent it from being unable to be disassembled.
[0031] The sealing ring 17 is annular and is located outside the fixing plate 9 . The height of the sealing ring 17 is higher than that of the fixing plate 9 . The hammer body 1 is tapered as a whole.
[0032] The main function of the sealing ring 17 is to protect the fixing plate 9, the motor 10 and the storage wheel 11. In addition to providing installation space for the fixing plate 9, the motor 10 and the storage wheel 11, it can also prevent water from entering the interior of the sealing ring 17.
[0033] The working principle and use process of this utility model:
[0034] First, the hammer head 3 is mounted to the bottom of the hammer body 1 by engaging with the mounting hole 2. Then, the weight block 21 is lifted by a crane or other device and placed above the sealing ring 17. After adjusting the designated position, the bolt 20 is engaged with the sealing plate 19 and the screw hole 18 respectively, so that the sealing plate 19 seals the inside of the sealing ring 17.
[0035] Secondly, the lifting ear 24 is installed into the inside of the slide groove 22 through the sliding action of the slider 23 and the slide groove 22. After the two sides of the lifting ear 24 are moved to the designated position, the second bolt 25 is engaged with the weight block 21, so that the lifting ear 24 is fixed. After connecting the lifting device to the lifting ear 24, the hammer body 1 is lifted as a whole, and the motor 10 is started to drive the storage wheel 11 to rotate, the wire rope 12 is wound and pulled upward, and the billiard ball 13 is pulled upward at the same time, so that the connecting plate 14 contacts the bottom of the limit bracket 8;
[0036] After the hammer body 1 is lifted and carried to the designated location, it is allowed to freely fall downward. At this time, the striker 4 will first contact the water surface. Since the tip of the striker 4 is downward, it will break the tension of the water after contacting the water surface. Therefore, when the hammer body 1 is carried as a whole, the resistance with the water will be greatly reduced, thereby increasing the falling speed and the impact force, making it easier to break the bottom of the cave;
[0037] Finally, the motor 10 is rotated in the opposite direction quickly, so that the billiard ball 13 has a free-fall effect and falls to the bottom of the fixed groove 7, thereby achieving the effect of a second impact of the hammer body 1 and improving the efficiency of the impact.
