Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a tamping device for road construction. Background Art

[0002] A road compaction plate compactor is a type of engineering machinery used to compact materials such as soil, asphalt or concrete. It is commonly used in road construction, infrastructure construction and other civil engineering projects. The working principle of a plate compactor is to compact the soil or other materials through repeated impact and vibration of a heavy hammer, thereby reducing gaps and increasing density.

[0003] After searching, a utility model with announcement number CN215714436U was found, which is a road compaction equipment for road construction, including a road plate compactor body, and two fixed plates are fixedly installed on the top surface of the lower right end of the road plate compactor body by bolts. The two fixed plates are respectively arranged at the front and rear ends of the road plate compactor body, and the top surfaces of the two fixed plates are respectively movably sleeved with fixed columns, and the interiors of the two fixed columns are respectively movably sleeved with sliding rods. The right end outer walls of the two fixed columns are respectively provided with sliding grooves, and push-pull rods are movably sleeved in the sliding grooves of the right end outer walls of the two fixed columns. The left sides of the push-pull rods are respectively fixedly connected to the right end outer walls of the two sliding rods, and the sides of the right ends of the two fixed plates close to each other are fixedly connected with connecting plates, which effectively reduces the vibration felt by holding the push-pull rod, thereby effectively improving the comfort of holding the push-pull rod when operating the road plate compactor body and effectively reducing the feeling of fatigue.

[0004] The above patent application reduces the vibration transmission of the plate compactor by arranging push-pull rods to connect them vertically with the fixed columns outside the plate compactor through the reinforcement rods. However, during the construction process, since the road surface is not flat, the force generated by the impact of the plate compactor's hammer does not act solely in the vertical direction. Therefore, there is still room for improvement in the above shock-absorbing means, and the method of using the support wheels to lift the plate compactor for reversing still requires supporting the lifting plate compactor equipment, which is inconvenient to operate. Therefore, the present application designs a compaction equipment for road construction to solve this technical defect of the prior art. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a compacting device for road construction, which has the advantages of small vibration of the push-pull plate compactor and easy reversal.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a compacting device for road construction, comprising a plate compactor body, a support frame arranged outside the plate compactor body, and a push rod connected to the support frame for conveniently pushing the plate compactor body, wherein a rectangular slide groove is provided on the inner wall of the support frame, a vertical sliding member slides in the slide groove, a first shock-absorbing mechanism is connected between the vertical sliding member and the inner wall of the slide groove, wherein the vertical sliding member and the plate compactor body are connected to each other;

[0007] The vertical sliding member includes L-shaped corner brackets attached to the four right-angled sides of the sliding groove and reinforcement rods connected to the corner brackets, and the reinforcement rods include two respectively fixedly connected to the two groups of the corner brackets;

[0008] A folding piece and a folding cover are fixedly mounted on opposite surfaces of the plate compactor body and the vertical sliding member, respectively, and a second shock-absorbing mechanism is connected between the folding piece and the folding cover.

[0009] By adopting the above technical solution, the plate compactor body can continuously vibrate in the support frame during use, thereby reducing the impact force caused by the synchronous vibration of the support frame and improving the user comfort of the device.

[0010] As a preferred technical solution of the present invention, the first shock-absorbing mechanism includes hinged seats respectively fixed on the side surface of the vertical sliding member and the inner wall of the sliding groove, a telescopic rod connected between the two hinged seats, and a shock-absorbing spring located outside the telescopic rod;

[0011] Wherein, one end of the shock-absorbing spring is fixedly connected to the movable end extending from one of the hinge seats, and the other end is fixedly connected to the movable end extending from the other hinge seat.

[0012] By adopting the above technical solution, when the plate compactor body connected to the vertical sliding member vibrates, it can pull the vertical sliding member to slide continuously inside the support frame, and drive the two telescopic rods to swing through the vertical sliding member, thereby reducing the vibration force.

[0013] As a preferred technical solution of the present invention, the second shock absorbing mechanism includes a connecting seat rotatably connected to the corner piece and the folding cover on opposite sides, a piston fixedly connected to one of the connecting seats, and a piston cylinder fixedly connected to the other connecting seat, wherein the piston is slidably connected to the piston cylinder;

[0014] A partition is fixedly mounted on the inner wall of the piston cylinder, with a central hole for hydraulic oil to flow through. This technical solution allows the piston at one end to reciprocate relative to the piston cylinder, mitigating impact forces. It also allows the plate compactor to oscillate irregularly within the rectangular cavity of the support frame, preventing the force from being transmitted to the push rod.

[0015] As a preferred technical solution of the present invention, the first shock absorbing mechanism is tiltedly arranged in the slide groove, and two of them are symmetrically distributed up and down on one side surface of one of the angle codes.

[0016] The above technical solution can be used to improve applicability in dealing with vibration transmission in irregular directions.

[0017] As a preferred technical solution of the present invention, one side of the partition is filled with air, and the other side is filled with hydraulic oil.

[0018] By adopting the above technical solution, the impact kinetic energy can be converted into oil thermal energy, thereby reducing the overall impact force.

[0019] As an optimal technical solution of the present invention, connecting frames are fixedly installed on the front and rear side walls of the support frame, and the two connecting frames are fixed to the outside of the support frame by long connecting plate bolts. At the same time, the upper end of the connecting frame has an arc-shaped groove, and one end of the push rod is located in the groove at the upper end of the connecting frame and is rotatably connected to the support frame through a rotating shaft.

[0020] As a preferred technical solution of the present invention, a handle is fixedly installed on the side of the connecting frame, and the handle is located on both sides of the groove part of the connecting frame. The push rod is detachably equipped with an armrest on one end away from the support frame.

[0021] By adopting the above technical solution, on the one hand, the handle can provide a gripping position for lifting the support frame, and on the other hand, the handle can limit the swing limit position of the push rod relative to the support frame to avoid the push rod from detaching due to large swinging.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The compacting equipment for road construction is configured such that a support frame is connected to the outside of a plate compactor body via a second shock-absorbing mechanism and a vertical sliding member, and a push rod is installed on the outside of the support frame. The push rod connection is provided via the external support frame, which facilitates the swinging of the push rod to adjust the plate compactor body for reversing and improves flexibility. At the same time, the first shock-absorbing mechanism is provided in conjunction with the second shock-absorbing mechanism to connect the plate compactor body, so that during use, the plate compactor body can continuously vibrate within the support frame, thereby reducing the impact force transmitted by the synchronous vibration of the support frame, thereby improving the use comfort of the device.

[0029] 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.

[0030] See also Figures 1 to 2 In this embodiment, a compacting device for road construction includes a plate compactor body 1, a support frame 2 arranged outside the plate compactor body 1, and a push rod 4 connected to the support frame 2 for conveniently pushing the plate compactor body 1.

[0031] Among them, the support frame 2 is a rectangular frame with openings running through the top and bottom, and the size of the support frame 2 should be larger than the body size of the plate compactor body 1, so that a movable gap can be reserved between the support frame 2 and the plate compactor body 1, which facilitates the irregular swing of the plate compactor body 1 under vibration.

[0032] This design can indirectly transmit the vibration force generated by the plate compactor body 1 through the external support frame 2 outside the plate compactor body 1, so that the operator is less impacted by holding the push rod 4 outside the support frame 2.

[0033] See also Figure 2 In this embodiment, connecting frames 3 are fixedly installed on the front and rear side walls of the support frame 2. The two connecting frames 3 are fixed to the outside of the support frame 2 by long connecting plate bolts. At the same time, the upper end of the connecting frame 3 has an arc-shaped groove. One end of the push rod 4 is located in the groove at the upper end of the connecting frame 3 and is rotatably connected to the support frame 2 through a rotating shaft, so that the push rod 4 can swing flexibly relative to the support frame 2 to push the support frame 2, that is, to push the plate compactor body 1 for use.

[0034] It should be noted that a handle 301 is fixedly installed on the side of the connecting frame 3. The handle 301 is located on both sides of the groove part of the connecting frame 3. On the one hand, the handle 301 can provide a lifting and gripping position for the support frame 2. On the other hand, the handle 301 can limit the swinging limit position of the push rod 4 relative to the support frame 2 to avoid the push rod 4 from detaching due to large swinging.

[0035] It should be noted that a handrail 401 is detachably mounted on one end of the push rod 4 away from the support frame 2. The handrail 401 can improve the comfort of the user holding the push rod 4, and can be disassembled and flipped to adjust when the push rod 4 is swung to perform a reversing operation on the plate compactor body 1.

[0036] In this application, the push rod 4 is connected through the external support frame 2. Compared with the connection method of directly hingedly connecting the push rod 4 used to push the plate rammer body 1 to the outside of the plate rammer body 1, it has better flexibility and can achieve the reversing push of the plate rammer body 1 by only rotating it to one side.

[0037] See also Figure 2-3 In this embodiment, a rectangular slide groove 201 is opened on the inner wall of the support frame 2, and a vertical sliding member 5 slides in the slide groove 201. A first shock absorbing mechanism 6 is connected between the vertical sliding member 5 and the inner wall of the slide groove 201, wherein the vertical sliding member 5 and the plate compactor body 1 are connected to each other.

[0038] This design enables the plate compactor body 1 to drive the vertical sliding member 5 connected thereto to slide relative to the support frame 2 when vibrating, thereby reducing the synchronous vibration amplitude of the support frame 2 along with the plate compactor body 1 .

[0039] In detail, the vertical sliding member 5 includes an L-shaped corner code 501 that fits at the four right-angled sides of the slide groove 201 and a reinforcement rod 502 connecting the corner code 501, wherein the reinforcement rod 502 includes two respectively fixedly connected to two groups of corner codes 501, so that the four corner codes 501 can be distributed into two symmetrical groups.

[0040] Furthermore, the first shock absorbing mechanism 6 includes hinged seats 601 respectively fixed on the side of the vertical sliding member 5 and the inner wall of the slide groove 201, a telescopic rod 602 connected between the two hinged seats 601 and a shock absorbing spring 603 located outside the telescopic rod 602.

[0041] It should be noted that the orientation of the telescopic rod 602 is not limited in this application. One end of the shock-absorbing spring 603 is fixedly connected to the movable end extending from one of the hinged seats 601, and the other end is fixedly connected to the movable end extending from the other hinged seat 601.

[0042] It can be understood that the first shock-absorbing mechanism 6 is tiltedly arranged in the slide groove 201, and there are two symmetrically distributed up and down on one side surface of an angle code 501. The two hinged seats 601 are supported by the telescopic rod 602, so that the up and down vibration force of the angle code 501 in the slide groove 201 can be converted into the elastic potential energy of the shock-absorbing spring 603 for storage.

[0043] This design allows the vertical sliding member 5 to pull the vertical sliding member 5 to slide continuously on the inner side of the support frame 2 when the plate rammer body 1 connected to the vertical sliding member 5 vibrates, and the two telescopic rods 602 are driven to swing by the vertical sliding member 5, thereby reducing the vibration force. At this time, the vertical sliding member 5 prevents the vibration generated by the plate rammer body 1 from being transmitted to the end of the push rod 4 by continuously moving relative to the support frame 2.

[0044] See also Figure 3-4 In this embodiment, in order to transmit and block the irregular vibration of the plate compactor body 1 on the horizontal plane, a folding piece 8 and a folding cover 9 are fixedly installed on the opposite surfaces of the plate compactor body 1 and the vertical sliding member 5, and a second shock-absorbing mechanism 7 is connected between the folding piece 8 and the folding cover 9.

[0045] The two ends of the second shock absorbing mechanism 7 are respectively hinged to the ends of the angle piece 8 and the folding cover 9, thereby improving the mobility of the plate compactor body 1 relative to the support frame 2.

[0046] Furthermore, the second shock absorbing mechanism 7 includes a connecting seat 701 rotatably connected to the opposite side of the corner piece 8 and the folding cover 9, a piston 702 fixedly connected to one connecting seat 701, and a piston cylinder 703 fixedly connected to the other connecting seat 701. The piston 702 is slidably connected to the piston cylinder 703, and the piston cylinder 703 is filled with hydraulic oil as a medium.

[0047] Furthermore, a partition 704 is fixedly installed on the inner wall of the piston cylinder 703, and an oil hole 705 for the hydraulic oil to pass through is opened in the middle of the partition 704. One side of the partition 704 is filled with air and the other side is filled with hydraulic oil. After being squeezed by the piston 702, the hydraulic oil can pass through the oil hole 705 to the cavity on the other side. At this time, the hydraulic oil can act as a medium to hinder the rebound of the piston 702, thereby ensuring the round-trip buffering of the piston 702.

[0048] In another embodiment, two groups of second shock-absorbing mechanisms 7 distributed vertically may be provided between the angle piece 8 and the folding cover 9 to adapt to the plate compactor body 1 with greater vibration.

[0049] The working principle of the above embodiment is as follows: when using the plate compactor body 1, the operator pushes the support frame 2 by holding the push rod 4. At this time, the plate compactor body 1 connected to the support frame 2 can be pushed and used synchronously with the support frame 2. The heavy hammer part of the plate compactor body 1 extends to the bottom of the support frame 2 to compact the road, and the anti-impact force is transmitted through the outer shell of the plate compactor body 1;

[0050] The impact force generated by the plate compactor body 1 is first transmitted through the second shock-absorbing mechanism 7. The impact force drives the folding cover 9 on the outside of the plate compactor body 1 to move relative to the angle piece 8 on the inside of the support frame 2. At this time, the two connecting seats 701 connected to the angle piece 8 and the folding cover 9 move relative to each other, causing the piston 702 at one end to move back and forth relative to the piston cylinder 703 to reduce the impact force. This also causes the plate compactor body 1 to swing irregularly within the rectangular cavity of the support frame 2, thereby preventing the force from being transmitted to the push rod 4.

[0051] When compacting irregular raised stones, the plate compactor body 1 will vibrate in the vertical direction. At this time, the vertical impact force is transmitted through the angle piece 8, causing the angle bracket 501 fixedly connected to the angle bracket 8 to slide up and down relative to the slide groove 201 on the inner wall of the support frame 2. At the same time, the telescopic rod 602 in the first shock-absorbing mechanism 6 connected to the angle bracket 501 and the inner wall of the slide groove 201 is retracted and retracted, squeezing the shock-absorbing spring 603 to absorb the force and store energy. The continuous swing of the angle bracket 501 prevents the support frame 2 from swinging synchronously.

[0052] At this point, the vibration force generated by the plate compactor body 1 is transmitted to the push rod 4 of the support frame 2 and will no longer have a significant impact on the operator.

[0053] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
