Road surface compacting machine

Technical Field

The invention relates to a compaction mechanism, in particular to a road surface compaction machine, and belongs to the technical field of road surface maintenance equipment.

Background

In the process of highway construction and maintenance, in many cases, the road surface floating soil needs to be compacted, the existing method adopts a roller vehicle for compaction, the compaction efficiency is high, the compaction area is large, but the method is not suitable for key stress parts and the joint of two piers; chinese application No. 99119069.6 discloses a road surface compacting machine, which utilizes a fixing member to fix a soil punch with a drop hammer on a carrier vehicle, the punch includes a chassis support pad, a drop hammer and a drop hammer operating member, the drop hammer is repeatedly lifted by the operating member and hit on the chassis support pad when dropping, thereby compacting the surface of the soil, the fixing member can make the drop hammer switch between an operating state and a non-operating state, the drop hammer is moved along the end edge of the carrier vehicle by a driving member, the drop hammer compacting machine is suitable for compacting the soil near a pier, compacting the soil of a narrow groove and compacting the soil in repairing small blocks of road with small and dispersed areas; the device can be maintained for small roads, but the operation is limited, key stress parts and key compaction at the joint of two piers are not solved, so that in the prior art, equipment for realizing one-time compaction for the key parts is difficult, and a general compaction process only has one mode.

Disclosure of Invention

The technical problem to be solved is as follows: in order to solve the problems, the invention provides a pavement compacting machine which realizes the positioning compaction of an inner lifting device, the force application compaction of an outer force application rod and the fine compaction of a vibration machine, and ensures that the compaction part is strong in stress and can bear high pressure.

The technical scheme is as follows: the invention relates to a drop hammer type compacting machine, which comprises a vehicle body and a drop hammer mechanism arranged at the front end of the vehicle body; the drop hammer mechanism comprises a fixed cavity; and a compacting plate arranged at the bottom of the fixed cavity; and a vibrating machine disposed above the compacting plate; the inner lifting mechanism supporting frame is arranged at the top of the fixed cavity; the bottom of the inner lifting device is connected with the top of the vibration machine, and the top of the inner lifting device and the inner side of the inner lifting mechanism support frame are installed; and an external force application rod which penetrates through the fixed cavity and is installed at the bottom of the fixed cavity in a matching way with the two sides of the front surface of the compacting plate; and a force application platform arranged on the top of the external force application rod; and an outer guide bracket arranged on the front side of the vehicle body; the force application platform is movably embedded with the outer guide bracket; the middle part of the rear side of the force application platform of the vehicle body is vertically provided with a guide rod; a drop hammer is arranged on the guide rod; a traction steel wire is arranged at the top of the drop hammer; the traction steel wire is matched with the traction machine.

Furthermore, an inner groove is formed in the middle of the drop hammer; the inner groove is matched with the guide rod.

As a preferred embodiment, a plurality of groups of pulleys are arranged on the guide rod; the traction steel wire is matched and installed with the traction machine through the pulley.

Further, the inner lifting device is a hydraulic lifting device.

Has the advantages that: the drop hammer type compaction machine is divided into three compaction modes, and the corresponding modes can be selected according to specific conditions, wherein the key part of compaction is that the compaction is realized by an inner lifting device, the compaction is realized by an outer force applying rod and the compaction is realized by a vibration machine, so that the compaction position is ensured to be stressed strongly and can bear high pressure.

Detailed Description

As shown in fig. 1, the road surface compacting machine comprises a vehicle body 1 and a drop hammer mechanism arranged at the front end of the vehicle body; the drop hammer mechanism comprises a fixed cavity 3; and a compacting plate 4 arranged at the bottom of the fixed cavity; and a vibration machine 5 disposed above the compacting plate; and an inner lifting mechanism support frame 6 arranged at the top of the fixed cavity; the bottom of the inner lifting device 7 is connected with the top of the vibration machine, and the top of the inner lifting device is arranged at the inner side of the inner lifting mechanism support frame; and run through the fixed cavity, and the bottom cooperates with two sides of positive of the compacting plate and installs the external force application pole 8; and a force application platform 9 arranged on the top of the external force application rod; and an outer guide bracket 10 provided at the front side of the vehicle body; the force application platform 9 is movably embedded with the outer guide bracket 10; a guide rod 11 is vertically arranged in the middle of the rear side of the force application platform 9 of the vehicle body 1; a drop hammer 12 is arranged on the guide rod 11; the top of the drop hammer 12 is provided with a traction steel wire 2; the traction wire 2 is fitted to a hoisting machine (not shown).

An inner groove (not shown) is arranged in the middle of the drop hammer 12; the inner groove is fitted with the guide bar 11.

A plurality of groups of pulleys 13 are arranged on the guide rod 11; the traction steel wire 2 is matched and installed with a traction machine through a pulley 13.

The inner lifting device 7 is a hydraulic lifting device.

The following modes are used.

The vibrations compaction mode is fixed a position through the automobile body, carries out preliminary location through interior elevating gear after that, makes vibrations machinery and ground laminating, through advancing of automobile body, can realize road surface vibrations compaction.

In the positioning compaction mode, the road surface can be positioned and compacted by the up-and-down impact of the inner lifting device and the advancing of the vehicle body; during the positioning compaction process, vibration compaction can be added.

The main stress points are compacted, the impact is carried out downwards through the inner lifting device, when the inner lifting device reaches the bottom, an impact force is given to the force application platform through a drop hammer, and then the compaction is carried out through vibration again through a vibration machine; the main stress point compaction can be realized by repeating the steps.
