Description
Technical Field
[0001] The utility model relates to the technical field of bridge drilling, in particular to a drilling device for bridge construction. Background Technique
[0002] With the development of society, the rapid growth of the national economy, the continuous development of industrial and agricultural production, and the acceleration of the pace of human life, various bridges have been erected across the country. The construction of bridges has provided great convenience for people's travel, enabling people to easily cross natural or artificial obstacles. In the construction of bridges, it is usually necessary to carry out bored pile construction on the bridges, so it is generally necessary to drill holes in the bridges first. In the prior art, when drilling holes in bridges, a drilling rig is usually used. When the existing drilling rig is in use, usually the staff hold the handles on the drilling rig with both hands, then align the drill bit on the drilling rig with the position where the hole needs to be drilled, and then the staff start the drilling rig and push the handle forcefully to drill holes in the bridge. Sometimes the staff not only need to push the drilling rig forcefully with both hands, but also need to use their chests to resist the drilling rig and push forcefully. Moreover, when the existing drilling rig is in use, in order to ensure the stability of the drilling rig during drilling, the staff also need to waste a large amount of force. Therefore, the existing drilling rig is very inconvenient to use and wastes a lot of manpower when drilling holes. Content of the Utility Model
[0003] The purpose of the utility model is to provide a drilling device for bridge construction, which can facilitate drilling, is convenient to control the stability of the drilling rig during drilling, saves manpower, and can also conveniently adjust the drilling depth according to needs.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions:
[0005] A drilling device for bridge construction includes a base. On one side of the upper end of the base, a housing is vertically arranged. On the other side of the upper end of the base, a limiting groove is opened. On the lower side of one end of the housing close to the limiting groove, a first sliding opening is opened. Inside the housing, close to the first sliding opening, a first limiting rod is vertically arranged. A first rack is slidably connected to the outside of the first limiting rod. One end of the first rack close to the first sliding opening is provided with a slider slidably connected thereto. One end of the slider away from the first rack is provided with a pedal.
[0006] A horizontally arranged threaded rod is rotatably connected inside the limiting groove. A plurality of horizontally arranged support rods are equidistantly arranged inside the limiting groove. One end of the outer side of the threaded rod is slidably connected with a first push rod that is slidably connected to each support rod. The other end of the outer side of the threaded rod is threadedly connected with a second push rod that is slidably connected to each limiting rod. Springs are arranged between the first push rod and the second push rod on the outer side of each limiting rod. The lower end of the pedal is rotatably connected with a connecting rod that is rotatably connected to the first push rod;
[0007] A first limiting shaft is horizontally arranged inside the housing near the first rack. A first gear meshing with the first rack is rotatably connected to the outer side of the first limiting shaft. A second limiting shaft is horizontally arranged inside the housing near the first limiting shaft. A second gear is rotatably connected to the outer side of the second limiting shaft. A second sliding opening is formed in the housing along its height direction at the end far from the first sliding opening. A second limiting rod is vertically arranged inside the housing near the second sliding opening. A second rack meshing with the second gear is slidably connected to the outer side of the second limiting rod. A support plate slidably connected thereto is arranged at one end of the second rack close to the second sliding opening. A drilling machine is detachably arranged at one end of the support plate far from the second sliding opening.
[0008] By adopting the above technical solution, when drilling a hole in a bridge, the housing is stably placed at the position where the hole needs to be drilled through the base. Then the drilling machine is installed on the support plate, and the drilling machine is started. Hold the upper end of the housing by hand, and then step on the pedal with both feet. The pedal drives the slider to slide downward relative to the first sliding opening. The slider drives the rack to slide downward relative to the first limiting rod. The rack drives the first gear to rotate relative to the first limiting shaft. The first gear drives the second gear to rotate relative to the second limiting shaft. The second gear drives the second rack to slide downward relative to the second limiting rod. The rack drives the support plate to slide downward relative to the second sliding opening. The support plate drives the drilling machine to move downward to drill a hole in the bridge. During the downward movement of the pedal, the connecting rod is driven to rotate relative to it. The connecting rod drives the first push rod to slide relative to the threaded rod and the support rods, compressing the spring. After the staff stops stepping on the pedal, the pedal is driven to move upward and reset under the elastic force of the spring, so as to take out the drilling machine from the drill hole; By rotating the threaded rod, the second push rod is driven to move towards the direction close to the first push rod, compressing the spring. The thrust of the spring on the first push rod increases, so that the distance that the first push rod can slide relative to the threaded rod and the support rods by stepping on the pedal becomes smaller, thereby changing the depth of drilling the bridge by the drilling machine.
[0009] A further setting of the present utility model is that a handle is arranged at the upper end of the housing.
[0010] A further setting of the present utility model is that a knob is arranged at one end of the threaded rod far from the housing and passes through the base.
[0011] A further setting of the present utility model is as follows: One side of the end of the support plate away from the second sliding opening is rotatably connected to a first fixing plate, and the other side of the end of the support plate away from the second sliding opening is rotatably connected to a second fixing plate. A plurality of first fixing holes arranged at equal intervals are formed at the free end of the first fixing plate, and a plurality of second fixing holes corresponding to the first fixing holes one by one are formed at the free end of the second fixing plate. A fixing bolt that is detachably arranged and movably connected to the corresponding second fixing hole is movably connected inside each first fixing hole. A fixing nut is threadedly connected to one end of the outer side of each fixing bolt close to the second fixing plate. The drilling machine is fixed by the first fixing plate and the second fixing plate.
[0012] Compared with the prior art, the present utility model has the following beneficial effects:
[0013] First, it can facilitate the drilling of the bridge and save manpower at the same time. By the staff stepping on the pedal with both feet, the pedal moves downward, driving the first rack to move downward. The first rack drives the second rack to move downward through the first gear and the second gear, thereby driving the drilling machine to move downward for drilling. During the downward movement of the pedal, through the connecting rod, the first push rod compresses the spring to generate elastic force. After releasing the pedal, under the action of the spring elastic force, the drilling machine is driven to be taken out of the hole, which is convenient for drilling. During the drilling process of the drilling machine, the staff holds the handle with their hands and steps on the pedal to move downward. At the same time, when stepping on the pedal to move downward, a certain downward force is applied to the present experimental model, so as to reduce the vibration generated by the drilling machine during the drilling process and increase the stability during drilling.
[0014] Second, it can facilitate the control of the drilling depth. By rotating the threaded rod, the second push rod moves toward or away from the first push rod, changing the degree of compression of the spring by the second push rod. The thrust of the spring on the first push rod also changes. Thus, the distance of the first push rod driven by stepping on the pedal changes. The distance of the pedal moving downward changes, and the distance of the drilling machine moving downward also changes, thereby changing the drilling depth and being able to control the drilling machine to drill the bridge at a certain depth.
