[0041] Embodiment 1
[0042] The hot mix asphalt mixture in the middle of the steel bridge deck pavement is often compacted by a roller, while the corners are not suitable for construction with large machinery and often become the weak link of the pavement, affecting the overall construction quality of the pavement.
[0043] In view of this, an embodiment of the utility model provides a compaction device, which is applied to the corners of the steel bridge deck pavement layer, including: a blocking component 100, a rod core 200, a hammer 300 and a compaction component 400, the top of the rod core 200 is connected to the blocking component 100, the rod core 200 passes through the hammer 300 and the bottom is connected to the compaction component 400, the hammer 300 can fall from the bottom end of the blocking component 100 to the top end of the compaction component 400 to apply a vertical downward force to the compaction component 400.
[0044] After the corners of the steel bridge deck pavement are filled with asphalt mixture, the compaction assembly 400 is placed on the mixture, the hammer 300 is lifted to the top close to the blocking assembly 100, and then the hammer 300 is released and dropped. The hammer 300 will fall to the top of the compaction assembly 400, thereby applying a vertical downward force to the compaction assembly 400. Repeat the above operation many times until the compaction degree of the compaction assembly 400 reaches the corresponding index, and then the compaction device can be moved to the next area that needs to be compacted. According to the test data in the background, the number of compaction times of the hammer 300 can be predetermined through experiments to ensure the compaction degree of the corners on site.
[0045] The compaction device is suitable for the maintenance construction of the corners of the steel bridge deck pavement layer. It can ensure the compaction degree of the corners, thereby improving the overall construction quality of the road surface.
[0046] In an optional manner of this embodiment, the blocking assembly 100 includes a handle 110 and a blocking block 120 . The handle 110 is disposed on the top of the blocking block 120 , and the blocking block 120 is connected to the rod core 200 .
[0047] See also Figure 1 The handle 110 is a triangular rod structure with good stability. The bottom of the handle 110 is fixedly connected to the top of the stopper 120. The compacting device can be moved to the top of the area to be compacted by holding the handle 110. The bottom of the stopper 120 is fixedly connected to the rod core 200. The stopper 120 can limit the maximum height of the hammer 300, thereby limiting the maximum distance of the hammer 300 when it falls.
[0048] Furthermore, the stopper 120 is a truncated cone structure, and the diameter of the stopper 120 gradually increases from top to bottom.
[0049] Please continue to see Figure 1 The lower end surface of the stopper 120 serves to limit the hammer 300 , so setting the stopper 120 as a truncated cone structure with a diameter gradually increasing from top to bottom can save materials and reduce costs, making the compacting device lighter.
[0050] Furthermore, the hammer 300 is a hollow columnar structure, and the rod core 200 passes through the hollow portion of the hammer 300 along the axial direction.
[0051] The hammer 300 needs to reciprocate up and down along the axial direction of the rod core 200 , and therefore the hammer 300 needs to be set as a hollow structure so that the rod core 200 passes through the hollow part of the hammer 300 .
[0052] Furthermore, the diameter of the bottom end of the stopper 120 is greater than the outer diameter of the hammer 300 .
[0053] Since the lower end of the stopper 120 serves to limit the hammer 300, the diameter of the bottom end of the stopper 120 needs to be larger than the outer diameter of the hammer 300, so that when the hammer 300 moves to the bottom end of the stopper 120, it is blocked by the stopper 120 and cannot continue to move upward.
[0054] Furthermore, the diameter of the top end of the stopper 120 is equal to the diameter of the rod core 200 , which can effectively save the manufacturing material of the stopper 120 , reduce the cost, and make the compacting device more portable.
[0055] In an optional manner of this embodiment, the compaction assembly 400 includes a shock absorbing block 410 and a compaction plate 420. The shock absorbing block 410 is connected to the top of the compaction plate 420, the bottom of the rod core 200 is connected to the shock absorbing block 410, and the hammer 300 can fall to the top of the shock absorbing block 410.
[0056] See also Figure 1 and Figure 3 The bottom of the shock absorbing block 410 is fixedly connected to the compacting plate 420, and the rod core 200 is inserted into the shock absorbing block 410 and connected to the shock absorbing block 410. The shock absorbing block 410 limits the lowest position of the hammer 300 when it falls. The hammer 300 falls to the top of the shock absorbing block 410. The shock absorbing block 410 can play a certain role in shock absorption and buffering the falling of the hammer 300. The impact force of the falling hammer 300 is transmitted to the compacting plate 420 through the shock absorbing block 410, so that the corners of the scene are gradually compacted.
[0057] Furthermore, the shock absorbing block 410 is a hollow columnar structure, and the rod core 200 penetrates the shock absorbing block 410 along the axial direction and is bolted to the shock absorbing block 410 .
[0058] See also Figure 2 During the compaction process, the hammer 300 falls and repeatedly impacts the shock absorbing block 410. The shock absorbing block 410 needs to be stably connected to the rod core 200. Therefore, the shock absorbing block 410 is set to a hollow structure, and the rod core 200 penetrates to the bottom of the shock absorbing block 410 and is connected to the shock absorbing block 410 by bolts.
[0059] Furthermore, the inner diameter of the shock absorbing block 410 is equal to the diameter of the rod core 200 .
[0060] The advantage of such a configuration is that the shock absorbing block 410 and the rod core 200 are interference-fitted, which increases the compactness of the compacting device as a whole and the stability of the connection, and ensures that the compacting device remains stable and reliable after multiple uses.
[0061] Furthermore, the outer diameter of the shock absorbing block 410 is equal to the outer diameter of the hammer 300 .
[0062] Since the upper end surface of the damping block 410 has a limiting effect on the hammer 300, the outer diameter of the damping block 410 needs to be not less than the outer diameter of the hammer 300, so that when the hammer 300 moves to the upper end surface of the damping block 410, it is blocked by the damping block 410 and cannot continue to move downward. The advantage of setting the outer diameter of the damping block 410 to be equal to the outer diameter of the hammer 300 is that it can save materials and costs, and make the compacting device lighter.
[0063] The method of using the compaction device of this embodiment is as follows: after the corners of the steel bridge deck pavement are filled with asphalt mixture, the compaction plate 420 is placed on the mixture, the hammer 300 is lifted to the top to abut against the stopper 120 to ensure the effective stroke of the hammer 300, and the hammer 300 is released and dropped. Repeat the above operation until the compaction degree reaches the corresponding index, and then move to the next area to be compacted. The number of compaction times of the hammer 300 can be determined in advance through experiments based on the background test data, so as to ensure the compaction degree of the corners on site.
[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
