Description

Technical Field

[0001] The utility model relates to the technical field of construction auxiliary facilities, in particular to an expanding pile device for municipal road bridges. Background Technique

[0002] The pile driver consists of a pile hammer, a pile frame and auxiliary equipment, etc. The pile hammer is attached between two parallel vertical guide rods (commonly known as the gantry) at the front of the pile frame and is lifted by a lifting hook. The pile frame is a steel structure tower. A winch is provided 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 pile expanding direction and make the pile accurately penetrate the formation according to the designed orientation.

[0003] During the pile expanding work of the existing pile driver, since the frame of the existing pile driver is mostly directly supported on the ground, when there is a slight displacement of the vehicle body due to an accident, without the restraint of the column, it is very easy for the column of the support frame to deviate from the established position, resulting in the deviation of the pile expanding position. Content of the Utility Model

[0004] The purpose of the utility model is to provide an expanding pile device for municipal road bridges in view of the deficiencies of the prior art to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An expanding pile device for municipal road bridges, including a vehicle body, on the surface of which a pile frame is installed. On the surface of the pile frame, a machine body is installed. And at the bottom of the machine body and at the end of the vehicle body, an installation foot is installed. A chute is opened on the surface of the installation foot, and the position of the chute is on the outer surface of the installation foot. A rotating shaft is inserted into the top of the installation foot. The surface of the rotating shaft extends into the inner top of the installation foot, and a gear set is installed at the end of the rotating shaft. The center position of the surface of the gear set is fixedly connected with a lead screw. An installation block is slidably connected in the chute of the installation foot, and a support column is fixedly sleeved on the surface of the installation block.

[0006] As a preferred technical solution of the utility model, the gear set is composed of two bevel gears, and the two bevel gears are distributed at an angle of 90 degrees to each other. The center of the bottom surface of the bevel gear located at the inner top of the installation foot is fixedly connected with the top of the lead screw, which can effectively ensure the center of gravity stability of the whole device and meet the long-term use of the device.

[0007] As a preferred technical solution of the utility model, a bearing is fixedly connected to the inner bottom end of the installation foot, and the bearing is installed on the surface of the end of the lead screw, which more efficiently strengthens the matching coordination of each component during the operation of the whole device and effectively reduces the probability of various accidents that may occur during use.

[0008] As a preferred technical solution of the present utility model, a steel drill rod is rotatably inserted at the top end of the support column, and a threaded shaft is fixedly connected to the end of the steel drill rod and located inside the support column. The end of the threaded shaft is rotatably inserted with a knob. Through the matching of the overall device during use, each component of the overall device is run-in to strengthen the coordination of the overall device during use.

[0009] As a preferred technical solution of the present utility model, the end of the threaded shaft is inserted into the top end inside the knob, and the appearance of the threaded shaft is spiral-shaped, which further strengthens the matching strength of the overall device during use and avoids the situation of asymmetric component matching during the use of the overall device.

[0010] As a preferred technical solution of the present utility model, one end of the mounting block extends into the mounting foot through a chute and is threadedly sleeved on the surface of the lead screw, and the other end extends out of the mounting foot and is fixedly sleeved with the support column. The overall device is supported jointly according to the existing structure to strengthen the coordination performance of the overall device during use and enhance the durability of the overall device during use.

[0011] As a preferred technical solution of the present utility model, a threaded groove is provided on the inner wall of the steel drill rod, and the size of the threaded groove is consistent with the specification of the threaded shaft. By strengthening the flexible control ability of the overall device, the probability of the overall device malfunctioning during use is weakened.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] For this pile expanding device for municipal road bridges, the screw rod is driven by the rotating shaft to control the support column to abut against the ground to position the pile frame. The knob drives the threaded shaft to control the steel drill rod to insert into the ground to limit the position and angle of the pile frame. Then, the machine body breaks the soil on the surface of the pile frame to expand the pile, thereby achieving flexible control of the overall device, strengthening the practical performance of the overall device, and improving the defect that most existing pile expanders are static on the ground and there is no resistance to hold back when the vehicle body has a slight displacement due to an accident.

[0021] As Figures 1-4 shown, a pile expanding device for municipal road bridges in this embodiment includes a vehicle body 1. A pile frame 2 is installed on the surface of the vehicle body 1. A machine body 3 is installed on the surface of the pile frame 2. And a mounting foot 4 is installed at the bottom of the machine body 3 and at the end of the vehicle body 1. The mounting foot 4 is used to support the pile frame 2 and prevent the bottom end of the pile frame 2 from colliding with the vehicle body 1. A chute is formed on the surface of the mounting foot 4, and the position of the chute is on the outer surface of the mounting foot 4. A rotating shaft 5 is inserted into the top end of the mounting foot 4. The surface of the rotating shaft 5 extends into the inner top end of the mounting foot 4. And a gear set 6 is installed at the end of the rotating shaft 5. The gear set 6 is used to provide power for the rotation of the lead screw 7. The center position of the surface of the gear set 6 is fixedly connected with a lead screw 7. A mounting block 9 is slidably connected in the chute of the mounting foot 4. And a support column 10 is sleeved and fixed on the surface of the mounting block 9. The support column 10 is used to strengthen the supporting force of the pile frame 2.

[0022] Furthermore, the gear set 6 is composed of two bevel gears, and the two bevel gears are distributed at a ninety-degree angle to each other. The center of the bottom surface of the bevel gear located at the inner top end of the mounting foot 4 is fixedly connected to the top end of the lead screw 7. The gear set 6 is used to transmit the power of the rotating shaft 5 to drive the lead screw 7 to rotate.

[0023] Further, a bearing 8 is fixedly connected to the inner bottom end of the mounting foot 4, and the bearing 8 is mounted on the end surface of the lead screw 7. The bearing 8 assists the lead screw 7 to maintain stability.

[0024] Further, a steel drill rod 11 is rotatably inserted into the top end of the support column 10, and a threaded shaft 12 is fixedly connected to the end of the steel drill rod 11 and located inside the support column 10. A knob 13 is rotatably inserted into the end of the threaded shaft 12. The steel drill rod 11 is inserted into the ground to strengthen the stability of the support column 10.

[0025] Furthermore, the end of the threaded shaft 12 is inserted into the top end inside the knob 13, and the appearance of the threaded shaft 12 is spiral. The threaded shaft 12 is used to drive the steel drill rod 11 to move downward.

[0026] Further, one end of the mounting block 9 extends into the mounting foot 4 through a chute and is threadedly sleeved on the surface of the lead screw 7, and the other end extends out of the mounting foot 4 and is fixedly sleeved with the support column 10. The mounting block 9 provides power for the position change of the support column 10.

[0027] Furthermore, a threaded groove is formed in the inner wall of the steel drill rod 11, and the size of the threaded groove is the same as the specification of the threaded shaft 12. The threaded shaft 12 is used to drive the steel drill rod 11 so that the steel drill rod 11 is inserted into the ground.

[0028] The usage method of this embodiment is as follows: When in use, please refer to Figures 1-4 , first, the operator needs to manually control the vehicle body 1 to drive to a predetermined position and stop steadily. Then, operate the pile frame 2 to be vertical at the end of the vehicle body 1, and operate the machine body 3 to perform pile expansion work. During the process of the pile frame 2 being erected, according to the different current terrain environments, manually control the rotation of the rotating shaft 5, and then drive the gear set 6 to mesh with each other by means of the rotating shaft 5 and drive the lead screw 7 to rotate. At the same time, support the lead screw 7 with the bearing 8, and use the rotation of the lead screw 7 to control the sliding displacement of the mounting block 9 on the surface of the mounting foot 4, so as to drive the adjustment of the height of the support column 10. When the bottom of the support column 10 touches the ground, then continue to manually rotate the knob 13 by the operator, and use the rotation of the knob 13 to control the threaded shaft 12 to drive the steel drill rod 11 to extend into the ground, so as to limit the position of the support column 10 on the vehicle body 1. This avoids the situation that when the vehicle body 1 has a slight displacement due to an accident without resistance to hold it back, resulting in a slight displacement of the pile frame 2.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
