Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road construction, in particular to a compaction device for road construction. Background Technique
[0002] Road construction compaction refers to the work of using compaction machinery to compact and reinforce the roadbed or road surface during road construction or repair. Compaction is to increase the density and bearing capacity of the roadbed or road surface to improve the durability and safety of the road. Compaction machinery usually compacts materials such as soil, gravel or asphalt concrete on the roadbed or road surface through vibration or compaction action, making them closely combined, reducing voids, and increasing density and bearing capacity. Compaction work is a very important part of road construction and can effectively improve the quality and service performance of the road.
[0003] When using a dynamic compactor for compaction work in road construction, usually after driving to the compaction site, the compaction block is magnetically attracted by the structure lifted by the dynamic compactor and then lifted above. Then, the lifted structure can be separated from the compaction block by power-off, so that the compaction block can only fall to the ground to compact the ground. Therefore, during the falling process of the compaction block, it is impossible to achieve straight-line falling, it is easy to deviate, and the compaction block cannot ensure planar falling to fully contact the ground for compaction treatment, resulting in poor compaction effect. Therefore, the utility model designs a compaction device for road construction that can ensure straight-line falling and prevent deviation to solve this defect of the existing technology. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the utility model provides a compaction device for road construction, which has the advantages of being able to ensure straight-line falling and prevent deviation during compaction, etc.
[0005] To achieve the above object, the utility model provides the following technical solution: A compaction device for road construction, comprising a mounting seat, two mobile vehicle-mounted seats, rollers and an assembly seat;
[0006] Mobile vehicle-mounted seats are fixedly installed on both the left and right sides of the mounting seat. Rollers are rotatably connected to the front and rear sides of the mobile vehicle-mounted seats. An assembly seat fixedly installed on a crane by fastening screws is installed on the left side of the left mobile vehicle-mounted seat;
[0007] An extension structure that can cooperate with the compaction construction to vertically fall is provided on the mounting seat;
[0008] A counterweight assembly that can adjust the counterweight according to the compaction area is provided on the extension structure;
[0009] An adjustment support assembly for supporting and limiting the counterweight assembly to facilitate the movement of the overall device is also provided on the mounting seat.
[0010] As a preferred technical solution of the present utility model, the stretching structure includes a number of stainless steel telescopic columns fixedly installed on the inner wall of the mounting base. The top of the stainless steel telescopic column is fixedly installed with an L-shaped stainless steel stress bar. A magnetic metal plate is fixedly installed between the bottoms of the L-shaped stainless steel stress bars. An electromagnet seat is magnetically fixed on the top of the magnetic metal plate. A rope passing hole for the hoisting rope of the crane to pass through and be fixed is opened on the top of the electromagnet seat.
[0011] As a preferred technical solution of the present utility model, a guide cylinder located outside the electromagnet seat is fixedly installed between the inner sides of the L-shaped stainless steel stress bars.
[0012] As a preferred technical solution of the present utility model, the counterweight assembly includes a fixed ramming block fixedly installed on the bottom of the magnetic metal plate. A counterweight ring is sleeved outside the fixed ramming block. Threaded rods are fixedly installed on the top inner and outer circles of the counterweight ring and the top outer circle of the fixed ramming block. Assembly blocks are sleeved between the threaded rods on the counterweight ring and the threaded rods on the fixed ramming block. A fastening nut for locking and fixing the assembly block is threadedly connected to the outside of the threaded rod.
[0013] As a preferred technical solution of the present utility model, when the stainless steel telescopic column is in a fully retracted state, the lower surface of the fixed ramming block is lower than the lower surface of the roller.
[0014] As a preferred technical solution of the present utility model, the adjusting support assembly includes a number of limit seats and hydraulic push rods fixedly installed on the bottom of the mounting base.

[0015] Compared with the prior art, the technical solution of the present utility model has the following beneficial effects:
[0016] This road construction ramming equipment is fixedly installed with the assembly seat and the crane. When the crane works to drive the mobile vehicle-mounted seat to move to the dynamic compaction area through the rollers, at the same time, the counterweight assembly is hoisted and separated by the hoisting rope of the crane and then falls straight down. Under the linear telescopic action of the stretching structure, the counterweight assembly moves straight down to make full contact with the ground for compaction treatment, avoiding the phenomenon of deviation. The counterweight assembly can be assembled according to the area of dynamic compaction, improving the adaptability of dynamic compaction. The setting of the adjusting support assembly facilitates the retraction and support of the counterweight assembly after dynamic compaction is completed, avoiding contact with the ground and facilitating the transfer to the next dynamic compaction location.

Specific implementation manners
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1 to 4 , a ramming device for road construction in this embodiment, includes a mounting seat 1, two mobile vehicle-mounted seats 2, rollers 3 and an assembly seat 4.
[0024] It should be noted that mobile vehicle-mounted seats 2 are fixedly installed on both the left and right sides of the mounting seat 1. Rollers 3 are rotatably connected to both the front and rear sides of the mobile vehicle-mounted seats 2. An assembly seat 4 fixedly installed on the left side of the left mobile vehicle-mounted seat 2 through fastening screws is fixedly installed on a crane.
[0025] In this embodiment, the mounting seat 1 is provided with an extension structure that can cooperate with the ramming construction to vertically drop.
[0026] It should be noted that the extension structure includes a number of stainless steel telescopic columns 5 fixedly installed on the inner wall of the mounting seat 1. An L-shaped stainless steel stress rod 6 is fixedly installed on the top of the stainless steel telescopic column 5. A magnetic attraction metal plate 7 is fixedly installed between the bottoms of the L-shaped stainless steel stress rods 6. An electromagnet seat 8 is magnetically fixed on the top of the magnetic attraction metal plate 7. A rope-passing hole 9 for passing and fixing the lifting rope of the crane is opened on the top of the electromagnet seat 8.
[0027] The magnetic attraction metal plate 7 is a magnetic attraction material that can be magnetically adsorbed by the electromagnet seat 8.
[0028] The stainless steel telescopic column 5 is composed of a number of stainless steel support cylinders that are slidably connected to each other, and the topmost stainless steel support cylinder and the bottommost stainless steel support cylinder are respectively connected to the L-shaped stainless steel force-bearing rod 6 and the magnetic attraction metal plate 7.
[0029] A guide cylinder 10 located outside the electromagnet seat 8 is fixedly installed between the inner sides of the L-shaped stainless steel force-bearing rod 6.
[0030] The inner diameter of the guide cylinder 10 is 1 - 5 cm larger than the diameter of the electromagnet seat 8.
[0031] The guide cylinder 10 is a hollow plastic cylinder.
[0032] In this embodiment, the stretching structure is provided with a counterweight assembly that can adjust the counterweight according to the ramming area.
[0033] It should be noted that the counterweight assembly includes a fixed ramming block 11 fixedly installed at the bottom of the magnetic attraction metal plate 7. A counterweight ring 12 is sleeved outside the fixed ramming block 11. Threaded rods 13 are fixedly installed at the top inner and outer circles of the counterweight ring 12 and the top outer circle of the fixed ramming block 11. Assembly blocks 14 are sleeved between the threaded rods 13 on the counterweight ring 12 and the threaded rods 13 on the fixed ramming block 11. A fastening nut 15 for locking and fixing the assembly block 14 is threadedly connected to the outside of the threaded rod 13.
[0034] When the stainless steel telescopic column 5 is in a fully retracted state, the lower surface of the fixed ramming block 11 is lower than the lower surface of the roller 3.
[0035] The lower surface of the counterweight ring 12 is flush with the lower surface of the fixed ramming block 11. The counterweight ring 12 is in a toroidal shape, and the fixed ramming block 11 is in a cylindrical shape.
[0036] In this embodiment, the mounting base 1 is also provided with an adjustment support assembly for supporting and limiting the counterweight assembly to facilitate the movement of the overall device.
[0037] It should be noted that the adjustment support assembly includes a number of limit seats 16 and hydraulic push rods 17 fixedly installed at the bottom of the mounting base 1. The limit seats 16 and the hydraulic push rods 17 are in one-to-one correspondence. A support plate 18 passing through the limit seat 16 is installed at the push rod of the hydraulic push rod 17.
[0038] The working principle of the above embodiment is as follows:
[0039] While docking with the crane through the installed mounting base 1 and fixing it by tightening the screws, the lifting rope of the crane is tied and fixed to the set rope passing hole 9. Then, after starting the crane and moving it, with the cooperation of the rolling of the rollers 3, when the whole device moves to the dynamic compaction site, according to the single area to be compacted, the set counterweight ring 12 can be sleeved outside the fixed compaction block 11, so that the combined diameter of the multiple counterweight rings 12 and the fixed compaction block 11 is equal to the diameter of the single surface to be compacted. And by sleeving the set assembly block 14 outside the threaded rod 13 and tightening the set fastening nut 15, the splicing and connection fixation of the counterweight ring 12 and the fixed compaction block 11 can be realized. (It should be noted that when sleeving and assembling the counterweight ring 12 and the fixed compaction block 11, the counterweight ring 12 is sleeved outside the fixed compaction block 11, and the counterweight ring 12 with a larger inner diameter is continuously sleeved outside the counterweight ring 12 sleeved on the fixed compaction block 11, and so on for sleeving and stacking, so that the combined diameter of the fixed compaction block 11 and the multiple counterweight rings 12 is equal to the diameter of the surface to be compacted. And after the combination is completed, the assembly block 14 is inserted between the threaded rod 13 on the fixed compaction block 11 and the innermost counterweight ring 12 and between the threaded rods 13 on two adjacent counterweight rings 12, and the combination is fixed by cooperating with the tightening of the fastening nut 15), thereby improving the adaptability of the assembled counterweight to the compacted area;
[0040] Thus, it is ensured that after the assembly is completed according to the compacted area and the weight is adjusted, the crane can lift it (at this time, the set electromagnet seat 8 is energized to magnetically adsorb the magnetic metal plate 7). While pulling the electromagnet seat 8 to move upward and synchronously driving the counterweight assembly to move upward, the stainless steel telescopic column 5 and the L-shaped stainless steel stress rod 6 are combined and linearly extended synchronously. Then, after the counterweight assembly moves to the top, by cutting off the power supply of the set electromagnet seat 8 to separate it from the magnetic metal plate 7, under the action of the gravity of the counterweight assembly, under the contraction action of the stainless steel telescopic column 5 and the connection and traction action of the L-shaped stainless steel stress rod 6, the counterweight assembly moves linearly downward to fully contact the ground for compaction treatment, avoiding the phenomenon of falling deviation and poor compaction effect caused by the non-supplemented contact between the falling surface of the counterweight assembly and the ground;
[0041] In addition, after the compaction is completed, with the cooperation of the falling of the lifting rope of the crane and the guiding function of the set guiding cylinder 10, the electromagnet seat 8 on the lifting rope can be hoisted and dropped into the internal of the guiding cylinder 10 for directional dropping to contact the magnetic metal plate 7, ensuring that the electromagnet seat 8 can be accurately adsorbed to the magnetic metal plate 7 when it falls, avoiding the time-consuming and laborious traditional manual auxiliary docking;
[0042] In addition, when it is necessary to move to the next ramming location, by restarting the lifting rope on the crane to pull the combined weight ring 12 and the fixed ramming block 11 upward above the support plate 18, the hydraulic push rod 17 can be activated to work to push the support plate 18 to move. Under the support and limit action of the limit seat 16, the support plate 18 supports the combined weight ring 12 and the fixed ramming block 11 to separate from the ground, so as to facilitate the crane to start and drive the whole equipment to move to the next ramming location.
[0043] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed power connection technology will not be elaborated in the text.
