Description
BACKGROUND Technical Field The present invention relates to the technical field of construction equipment, and in particular to a reaming device for road and bridge construction. Related Art In order to install road auxiliary tools such as soundproof screens and signs on roads and bridges, it is usually necessary to dispose embedded parts on guardrails on both sides of the roads and bridges to ensure the installation strength of the road auxiliary tools. The embedded parts need to be constructed at the same time during the construction of the roads and bridges, the construction difficulty is high and it is not easy to control a pre-buried position, which seriously affects the construction efficiency of the roads and bridges and the installation effect of the road auxiliary tools. During the construction of the roads, bridges and subway pipe galleries and the like, the pre-embedded parts disposed in advance need higher precision to achieve the same size as an installed device; however, the construction of high-precision embedded parts is difficult, which seriously affects progress of engineering construction. However, the precision of the embedded parts is low, and the device often cannot be installed due to the large deviation. A simpler method of installing the auxiliary tools is that, when the roads and bridges are constructed, the embedded parts are not set. After the completion of the work, embedded steel bars are fixed by straight hole drilling and rubber filling, and the road auxiliary tools are further installed. The method is easy to construct and high in efficiency, and there is no need to preset the embedded parts; since the holes drilled in the guardrails are straight holes with smooth inner walls, the installation strength of the road auxiliary tools is poor, and the road auxiliary toolscannot resist a strong external force effect. A method capable of improving the COTES installation strength is to groove the inner wall of the drilled straight holes. However, the work of grooving and reaming cannot be performed by the prior art. Summary Against the aforementioned shortcomings in the prior art, an objective of the present invention is to provide a reaming device for road and bridge construction.
To achieve the above objective, the present invention adopts the following technical solution: The technical problem to be solved by the present invention is how to overcome the deficiencies of the prior art, and provide a reaming device for road and bridge construction for road auxiliary tools installation of roads and bridges, and for bridge reinforcement and line fixing in a subway pipe gallery.
The technical solution adopted to achieve the above objective by the present invention is as follows: A reaming device for road and bridge construction, including a power machine, a mounting bracket, a connecting rod, a mounting rod, and a drill bit, where the mounting bracket is provided with a sliding rail, and the power machine is connected with the mounting bracket through the sliding rail; the power machine can move up and down through the guiding of the sliding rail, and the mounting rod is connected with the power machine through the connecting rod; the drill bit is disposed at the lower end of the mounting rod; by threaded connection, the drill bit and the mounting rod are detachable; a universal joint is disposed between the mounting rod and the connecting rod, and the mounting rod is further provided with a guiding device.
Further, the guiding device includes a guide rod sleeving the mounting rod through a copper sleeve and a sliding sleeve sleeving the connecting rod; a linkage rod is hinged to one end of the guide rod and the side wall of the sliding sleeve, and the other end of the guide rod is fixedly connected with a guide handle; a handle linkage rod with one end hinged to the sliding sleeve is hinged to the guide handle, and a handle adjusting wrench is further hinged to the sliding sleeve and the handlelinkage rod, and configured to adjust the inclination of the guide handle. HU101120 Further, the drill bit includes a cutter head and cutting heads; the number of the cutting heads is six, and the cutting heads are evenly distributed on the cutter head.
Further, the two ends of the connecting rod are provided with threads: and the connecting rod is connected with the universal joint and the power machine respectively through the threads, and is detachable.
The advantages of the present invention are as follows:
1. Grooving is implemented in straight holes, and the external force resistance of embedded steel bars fixed by rubber filling is enhanced.
2. The present invention can also be applied to the fields of bridge reinforcement, line laying of subway pipe galleries, and the like.
3. According to the present invention, a plurality of circular grooves can also be opened in the straight holes according to actual conditions, thereby further improving the adhesion strength of the rubber that fills the drilled holes of the embedded steel bars.
4. The reaming device according to the present invention can also replace an expansion bolt, especially in the fixing work of a curtain wall of a high-rise building.
5. The drill bit, the connecting rod, and the mounting rod are connected through threads, thereby facilitating dismantling and replacement.
Brief Description of Drawings FIG. 1 is a schematic view of an overall structure according to the present invention; FIG. 2 is a schematic view of an overall structure of a guide handle structure according to the present invention; and FIG. 3 is a schematic view of a drill bit. Description of Embodiments The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can beimplemented in various different ways as defined and covered by the claims. LU101126 As shown in FIGs, 1, 2, and 3, a reaming device for road and bridge construction includes a power machine 1, a mounting bracket 2, a connecting rod 3, a mounting rod 4, and a drill bit 5, where the mounting bracket 2 is provided with a sliding rail 21, and the power machine 1 is connected with the mounting bracket 2 through the sliding rail 21; the power machine 1 can move up and down through the guiding of the sliding rail 21, and the mounting rod 4 is connected with the power machine 1 through the connecting rod 3; the drill bit 5 is disposed at the lower end of the mounting rod 4; a universal joint 41 is disposed between the mounting rod 4 and the connecting rod 3, and the mounting rod 4 is further provided with a guiding device.
