Description

Technical Field

[0001] The utility model belongs to the technical field of pile hammer transportation, and particularly relates to a transportation fixing device for a hydraulic pile hammer. Background Technique

[0002] A hydraulic pile hammer is a pile driving machinery that uses the power of an excavator, its own weight, and the weight of the pile to drive the pile into the ground. Compared with traditional pile hammers, it has the advantages of low noise, no pollution, and small vibration, meeting environmental protection requirements, and having excellent dynamic characteristics and controllability. It mainly includes conventional type, high-frequency type, and non-resonant type. Different types of pile hammers are suitable for different geological environments; the conventional hydraulic pile hammer has a larger amplitude and is suitable for construction in cohesive soil. The high-frequency pile hammer is suitable for sandy soil, while the non-resonant type is suitable for areas with strict vibration restrictions.

[0003] The hydraulic pile hammer is huge in volume and requires the use of a transportation fixing device for auxiliary transportation. For example, a transportation fixing device for a hydraulic pile hammer recorded in the Chinese utility model patent document with the publication number CN213922836U fixes the components of its hydraulic pile hammer through an elastic structure. However, because the components of the pile hammer are huge in volume, when passing through a bumpy road section, the pile hammer components will shake inside it, and this shake will affect the normal driving of the special transport vehicle to a certain extent. In addition, it has limitations in lifting operations, resulting in an increase in the difficulty coefficient of transportation to a certain extent, and poor stability.

[0004] Therefore, it is very necessary to invent a transportation fixing device for a hydraulic pile hammer. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a transportation fixing device for a hydraulic pile hammer, which includes a pile hammer placement rack and a pile hammer fixing mechanism. The pile hammer placement rack is fixedly installed on a trailer, and a pile hammer fixing mechanism is fixedly installed on the pile hammer placement rack;

[0006] The pile hammer placement rack includes a fixed seat, a placement base, a notch, a mounting hole, a placement plate, and a blocking plate. A pile hammer fixing mechanism and a placement base are fixedly installed on the fixed seat. The placement base is arranged inside the pile hammer fixing mechanism. Notches are staggeredly arranged on both sides of the placement base. Mounting holes are opened on the placement base. The placement plate is fixedly installed on the placement base through the mounting holes, and a blocking plate is fixedly installed on the placement plate;

[0007] The fixing mechanism of the pile driver comprises a locking shaft, a fixing pressure rod, a fixed base, a worm wheel, a worm, a synchronous shaft and a driving motor. Two locking shafts are provided, and a plurality of the fixing pressure rods are fixedly mounted on the locking shaft. The locking shaft is rotatably mounted on the two fixed bases, and a worm wheel is rotatably mounted in one of the fixed bases. Either end of the locking shaft rotates through the fixed base to be fixedly connected to the worm wheel inside it. Two worm wheels are provided, and the worm wheel is meshed with the worm, and the worm is fixedly mounted on the synchronous shaft. The synchronous shaft is rotatably mounted inside the fixed base, and either end of the synchronous shaft rotates through the fixed base to be fixedly connected to the output end of the driving motor, and the driving motor is fixedly mounted on the fixed base.

[0008] Preferably, the placement base is a 'T'-shaped structure, locking shafts are provided below both sides of the placement base, and the notches provided on the placement base are aligned with the fixed pressing rods.

[0009] Preferably, the fixed pressing rod is a 'V'-shaped structure, and two groups of the fixed pressing rods are provided, and the two groups of the fixed pressing rods are arranged in a staggered manner.

[0010] Preferably, the placement plate fixedly mounted on the placement base is a "concave"-shaped structure, the groove on the placement plate is a trapezoidal groove, and the blocking plate fixedly mounted on the placement plate is a rectangular structure.

[0011] Preferably, the mounting hole opened on the placement base is arranged between the notches, and the notches opened on the placement base allow the fixed pressing rod to pass through.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model does not have any elastic components, and the pile hammer component structure is firmly fixed by a locking method. This fixing method can effectively prevent the whole from producing violent and uncontrollable shaking when passing through bumpy roads, thereby affecting the normal driving of the transport vehicle, and can minimize the traffic hazards generated during transportation. In addition, the pile hammer fixing mechanism has an arc-shaped motion trajectory, so the motion trajectory will not affect the subsequent lifting of the pile hammer component, thus avoiding the fixing method affecting the subsequent lifting operation, and reducing the difficulty of unloading and loading operations.
