DETAILED DESCRIPTION

The following is a further detailed description of an automatic acquisition device for hammer pile driving parameters provided by the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer with the following description. It should be noted that the accompanying drawings are in a very simplified form and in an inaccurate proportion, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

As shown in FIG1 , the automatic acquisition device for hammer pile driving parameters provided in this embodiment is used to collect the number of hits and the data of the penetration per hit during the construction of prefabricated pipe piles using the hammer method, and is particularly used for automatically recording the number of hits and the data of the penetration per hit during the final driving stage of the pile body. The automatic acquisition device for hammer pile driving parameters includes a bracket 10, a laser transmitter and receiver 30, a laser receiver 31, a fixing member 32 and a processor.

As shown in FIG. 1 and FIG. 2 , the main function of the bracket 10 is to guide the pile body 20 and control its verticality. The bracket 10 includes a bracket cylinder 11, a bracket base 12, a diagonal brace 13 and a servo mechanism 14. The bracket cylinder 11 is vertically arranged and fixedly connected to the bracket base 12 through the diagonal brace 13. A plurality of servo mechanisms 14 are arranged at intervals on the same horizontal plane of the bracket cylinder 11. During construction, the bracket is first installed in the area to be constructed so that the central axis of the bracket cylinder 11 coincides with the center line of the pile position, the pile body 20 is hoisted into the bracket cylinder 11, the bottom of the pile body 20 is made to enter the soil by hammering, and the verticality of the pile body 20 is adjusted by the servo mechanism 14.

The laser transmitter and receiver 30 is arranged on the bracket 10, for example, on the top or side wall of the bracket cylinder 11, and the laser receiver 31 is fixed to the pile body 20 through a fixing member 32, for example, fixed by a hoop-type clamp, a fastener, a wire binding, etc., and the position corresponds to the position of the laser transmitter and receiver 30. The laser transmitter and receiver 30 emits a laser to the laser receiver 31, and the distance D between the laser transmitter and receiver 30 and the laser receiver 31 can be measured, and the measurement data is sent to the processor. The laser receiver 31 can use a reflecting prism.

The processor is connected to the laser transmitter and receiver 30 by signal, and can receive the measurement data sent by the laser transmitter and receiver 30. The processor includes a counter for calculating the number of hammer strikes and a calculator for calculating the footage data. The calculator calculates the elevation of the pile top or the elevation of a preset point on the pile body 20 based on the measurement data, the elevation of the laser transmitter and receiver 30, and the distance between the laser receiver 31 and the pile top. Each hammer strike process will cause D to decrease rapidly and then remain constant. Therefore, the counter of the processor can automatically calculate the number of hammer strikes based on the change in the D value, and the calculator can calculate the footage data of each hammer strike.

During the construction process, when hammering reaches the last meter, the laser transmitter and receiver 30 emits laser to the laser receiver 31, and the processor automatically records the number of hammering and the penetration of each hammering. The recording principle is: the number of hammering is automatically increased by one after each hammering; the laser transmitter and receiver 30 automatically and continuously emits lasers, and the distance between the laser transmitter and receiver 30 and the laser receiver 31 is automatically measured, so as to calculate the penetration of each hammering, and the servo mechanism 14 is used to control the posture of the pile body 20.

In order to ensure the accuracy of the counting, a sound collection device 33 is provided on the bracket to collect the surrounding sound waves. The sound waves will change dramatically when hammering. Therefore, the number of hammering can be identified by the change in the intensity or frequency of the sound waves, so as to verify the number of hammering determined by the processor based on the measurement data. Of course, an accelerometer or an impact force tester can also be provided on the hammer body or pile body 20 to determine the number of hammering by acceleration or impact force, so as to verify the number of hammering determined by the processor based on the measurement data.

The automatic acquisition device for hammer pile driving parameters provided in this embodiment can emit laser lines to the laser receiver 31 through the laser transmitter 30, and the processor obtains the measurement data and automatically and continuously records the number of hammer blows and the penetration per blow, so as to assist the posture control during the driving process of the pile body 20. Moreover, the automatic acquisition device for hammer pile driving parameters has the advantages of simple structure, convenient installation, and easy operation.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
