Description

Technical Field

[0001] The invention belongs to the technical field of highway engineering, and in particular relates to a pile driver for highway bridge construction. Background Art

[0002] Pile drivers are divided into large and small types. Large pile drivers are composed of a pile hammer, a pile frame and ancillary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) in the front of the pile frame and is lifted by a lifting hook. The pile frame is a steel structure tower with a winch at the rear to lift the pile and the pile hammer. There is a guide frame composed of two guide rods in front of the pile frame to control the direction of piling so that the pile can be accurately penetrated into the formation according to the designed direction. The basic technical parameters of a pile driver are the weight of the impact part, the impact kinetic energy and the impact frequency. Due to the large size and heavy weight of large pile drivers, they are not convenient to use in highway bridge construction, especially in highway bridge repair projects, and small pile drivers are usually used.

[0003] A Chinese patent with application number CN201820868141.9 discloses a handheld electric pile driver, comprising a main frame, a fixing box is fixedly installed on the outer surface of the upper end of the main frame, and a lamp tube is fixedly installed on the outer surface of one side of the fixing box, a shock-absorbing spring column is fixedly installed on the outer surface of one side of the main frame, a handle is fixedly installed on the outer surface of one end of the shock-absorbing spring column, an electric wire is fixedly connected to the outer surface of one side of the handle, and a plug is fixedly connected to the outer surface of one end of the electric wire away from the handle, a second connecting column is fixedly installed on the outer surface of the other side of the main frame, and a rotating ring is fixedly installed on the middle outer surface of the second connecting column.

[0004] The existing small pile driver requires two workers to hold the two ends of the top of the pile driver respectively to achieve the stability of the pile driver. Even a small pile driver is relatively heavy, and it is very difficult for one worker to carry it. During the road and bridge repair construction process, frequent manual handling of equipment affects the construction period and increases the workload of workers. For this reason, an improved pile driver for highway bridge construction has been designed. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a pile driver for highway bridge construction to solve the above-mentioned problems in the background technology.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A pile driver for highway bridge construction comprises a moving device and a pile driving device escalably connected to the moving device;

[0008] The mobile device includes a base plate, a mobile wheel is installed at the rear end of the bottom of the base plate, a notch is opened at the front end of the base plate for a pile driving device to drive piles, two support columns are connected to the rear end of the base plate, a top beam frame is connected between the tops of the two support columns, and a first gripping portion is provided on the top beam frame for workers to hold conveniently.

[0009] By adopting the above structural design, the pile driver for highway bridge construction is a small handheld pile driver used for roadside piling. By adding a moving device to the piling device, the movement of the pile driver is facilitated. The device has a simple structure and is easy to carry, which increases the convenience of small-scale construction, avoids the impact of frequent transportation of equipment on the construction period, and reduces the workload of workers.

[0010] Furthermore, the cross-sectional shape of the top beam frame is U-shaped, a first sliding column is connected between the front end of the top beam frame and the bottom plate, a top plate is connected to the middle position of the top beam frame, a second sliding column is connected between the top plate and the bottom plate, and a spring is sleeved on the second sliding column.

When in use, only one person needs to hold the side grip on the outside of the base plate and start the driving motor to drive the spiral drill rod to drill holes. No two people are required to operate, which is more practical.

[0015] Furthermore, side gripping parts are connected to both sides of the base plate, and the side gripping parts include two L-shaped connecting rods arranged in parallel, a gripping rod is connected between the two connecting rods, and the first sliding sleeve is located between the two connecting rods.

[0016] Furthermore, the shape of the bottom plate is an arch shape, the notch on the front end of the bottom plate is semicircular, a slot is provided at the vertex of the outer edge of the notch, a pipe sleeve column is connected below the slot, the bottom of the pipe sleeve column is connected to the chassis, and a fixing cone passing through the pipe sleeve column and the chassis is passed through the slot.

[0017] By adopting the above structural design, a pipe sleeve column is provided at the bottom of the front end of the base plate, and a triangular structure is formed between the two movable wheels at the rear end, which is more stable. At the same time, a fixed cone is installed on the pipe sleeve column. When piling, the fixed cone is inserted into the roadside land, and the side grip is held with both hands.
