Technical Field

[0001] The utility model relates to the technical field of pressure hydraulic rammers, in particular to a pressure hydraulic rammer monitoring device. Background Art

[0002] A hydraulic rammer is a compaction machine that uses hydraulic power output to compact the foundation. When using a hydraulic rammer to compact the ground, when encountering a material with a hard surface, its uniform hydraulic strength is much lower than the instantaneous strength characteristics. The uniform rammer often requires a long time of hammering to crack the hard material, which wastes time and reduces the breakthrough efficiency. It is also impossible to collect data on the number of hammering times, explosive hammering force, and hammering speed of the rammer in order to better optimize the equipment.

[0003] Therefore, it is particularly important to design a pressure hydraulic rammer monitoring device to change the above technical defects and improve overall practicality. Utility Model Content

[0021] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0022] A pressure hydraulic tamping monitoring device comprises an outer cylinder 1, a lifting hydraulic cylinder 2 is arranged inside the outer cylinder 1, an accelerating sleeve rod 4 is fixed to the bottom end of the lifting hydraulic cylinder 2, a through electromagnet 401 is arranged on the top of the inner side of the accelerating sleeve rod 4, and an accelerating hammer rod 3 extending from the bottom of the outer cylinder 1 is arranged inside the accelerating sleeve rod 4;

[0023] The external structure size of the acceleration hammer rod 3 is adapted to the internal structure size of the acceleration sleeve rod 4. The connection between the acceleration hammer rod 3 and the acceleration sleeve rod 4 is a sliding connection. The tops of the left and right sides of the acceleration hammer rod 3 are provided with limit blocks used in conjunction with the acceleration sleeve rod 4.

[0024] In this embodiment, please refer to Figure 3 An extension plate 301 is fixed at the bottom of the acceleration hammer rod 3, a hammer head 302 is installed at the bottom end of the extension plate 301, a gravity sensor 303 is installed at the interlayer position at the bottom of the hammer head 302, and a counter 304 and a speed detector 305 are installed on the side walls of the hammer head 302 respectively. Under the detection of the gravity sensor 303, the counter 304 and the speed detector 305, the number of falls and the falling speed of the hammer head 302 can be collected, which is convenient for data collection and statistics of the staff. Nitrogen tanks 306 are installed on the left and right sides of the top of the extension plate 301, and the top of the nitrogen tank 306 is connected to an injection pipe 307, and a one-way air valve 308 is provided in the middle section of the injection pipe 307. A magnet block 309 used in conjunction with the electromagnet 401 is fixed at the top of the acceleration hammer rod 3;

[0025] A receiving controller is installed on the outer surface of the outer cylinder 1, and the receiving controller is connected to the gravity sensor 303, the counter 304, the speed detector 305, the one-way air valve 308, and the electromagnet 401 through wires, and the connection method is electrical connection. The receiving controller is remotely connected to the remote control console through a local area network, and the connection method between the electromagnet 401 and the magnet block 309 is magnetic adsorption.

[0026] The working process of the utility model is as follows: under the action of the lifting hydraulic cylinder 2, the hammer head 302 can be driven to fall at a uniform speed to perform conventional compaction operations on the road surface. However, when encountering hard materials during the compaction process, the acceleration of the hammer head 302 can be started, and the power of the electromagnet 401 can be turned off, so that the electromagnet 401 and the magnet block 309 that were originally adsorbed together lose their adsorption force, thereby causing the acceleration hammer rod 3 to fall inside the acceleration sleeve rod 4. At the moment of falling, the staff can remotely open the one-way air valve 308 through the receiving controller to allow the gas inside the nitrogen tank 306 to be ejected through the jet pipe 307, thereby realizing the acceleration of the hammer head 302, making the falling speed of the hammer head instantly faster, thereby increasing the force of the hammering and improving the efficiency of surface rupture. At the same time, under the detection of the gravity sensor 303, the counter 304, and the speed detector 305, the number of falls and the falling speed of the hammer head 302 can be collected, which is convenient for collecting data and convenient for the staff to count.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
