Description

Technical Field

[0001] The utility model relates to the technical field of piling equipment, in particular to a lifting and stabilizing device for a static pile driver. Background Art

[0002] A static pile driver is a common device used in construction piling. The static pile driver moves to the approximate location where the pile needs to be driven. The pile hoisting device lifts the cement pile and places it into the pile driving mechanism. The cement pile is pressed into the designated area by the pile driving mechanism. In order to ensure that the cement pile can enter the pile driving mechanism stably and quickly, there is a static pile driver available. For example, a Chinese utility model patent with the announcement number CN212452635U discloses a pile driver body including a mounting frame, a supporting device provided on the mounting frame, a movable frame provided on one side of the supporting device, and a counterweight block provided on the movable frame. A mounting seat is welded on one side of the mounting frame, a hydraulic rod 1 is installed on the mounting seat, a bottom plate is installed on the bottom of the hydraulic rod 1, a connecting seat is welded on one side of the mounting frame, a limiting plate is welded on the connecting seat, a hydraulic rod 2 is installed on the limiting plate, a movable rod is provided on the hydraulic rod 2, one end of the movable rod is fixed on the movable frame, the supporting device includes a supporting seat, a supporting frame is provided on the supporting seat, a supporting plate is welded on the supporting frame, a hydraulic rod 3 is installed on the supporting plate, an inner rod is provided on the hydraulic rod 3, a fixed box is provided at one end of the inner rod, and a cavity is provided on the fixed box. Since the cement pile will shake when the pile is hoisted, it takes a certain amount of time to move it into the pile driving mechanism. In this type of device, the position of the cement pile is positioned by setting a clamping ring, so that the cement pile can be quickly installed in the required position. However, when the clamping ring is positioned, the cement pile needs to enter the area enclosed by the clamping ring, and this area is small. If the cement pile deviates to one side of the clamping ring, the clamping ring on one side will push the cement pile, which reduces the efficiency of guiding and positioning the cement pile.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0020] Embodiment: A lifting and stabilizing device for a static pile driver, comprising a working platform 1, as shown in the attached Figure 1 As shown, a plurality of support frames 2 are installed on the working platform 1. Three groups of support frames 2 are arranged in a triangular state on the working platform 1. A fixing rod 3 is connected between the upper ends of the support frames 2. The fixing rod makes the support frames stable. A lifting component 4 is installed in the support frame 2. Figure 2 As shown, the movable end of the lifting assembly 4 is provided with a hinged connecting rod 5, and the ends of multiple sets of connecting rods 5 are equipped with a common pile guide 6. The lifting assembly 4 includes a motor 41 disposed within a base 7. A screw 42 is connected between the top seat 9 and the base 7 via a bearing, and the extended end of the motor 41 is connected to the lower end of the screw 42. Slide rods 43 are also symmetrically disposed between the top seat 9 and the base 7. A movable seat 44 is provided on the slide rod 43 and the screw 42, and the connecting rod 5 is hinged to the movable seat 44. The motor drives the screw to rotate, causing the movable seat to move along the slide rod. The movable seats in the three lifting assemblies move in coordination, thereby achieving horizontal movement of the pile guide within a circle. The pile guide 6 is disposed above the pile driving mechanism on the working platform 1.

[0021] The support stand 2 includes a base 7 fixed to the work platform 1, a support rod 8 is installed on the base 7, the upper end of the support rod 8 is provided with a top seat 9, and both ends of the top seat 9 have a rod body connecting portion 10, as shown in the attached Figure 3 As shown, the rod body connecting portion 10 has a slot 11, the fixing rod 3 is inserted into the slot 11 and the fixing rod 3 is connected to the rod body connecting portion 10 via screws. By inserting the fixing rod and then connecting via screws, the stability of the connection can be improved.

[0022] The pile guide 6 includes a main body 61, as shown in the attached Figure 4 As shown, a plurality of connecting sleeves 62 hinged to the connecting rod 5 are evenly installed on the side of the main body 61, and a guide channel 63 for guiding the pipe pile is provided in the main body 61. The cement pile will enter the guide channel and then enter the pile driving mechanism. The upper end entrance of the guide channel 63 is provided with a tapered sleeve 64 that is larger at the top and smaller at the bottom, so that the cement pile can be introduced into the pile body guide more smoothly and quickly; the circumference of the main body 61 is evenly provided with a plurality of side grooves 65, and the outer side of the main body 61 is provided with a plurality of rollers 66, and the wheel surface of the roller 66 passes through the side grooves 65 and is arranged in the guide channel 63. After the cement pile enters the guide channel, the roller contacts the circumferential surface of the cement pile, and the cement pile can enter the pile driving mechanism more smoothly. The setting of the roller can reduce the friction between the cement pile and the guide channel.

[0023] The working principle of the present invention is as follows: after the cement pile is lifted, the cement pile moves into the moving range of the pile body guide, and the pile body guide moves to the lower end of the cement pile under the joint drive of the lifting assembly, and the pile body guide continues to move, and the cement pile enters the pile body guide, and the pile body guide brings the cement pile into the pile driving mechanism. At the same time, the crane runs simultaneously along the moving path of the pile body guide, and after the cement pile enters the pile driving mechanism, the pile body guide withdraws from the upper end of the cement pile; through the guidance of the pile body guide, the larger moving range of the pile body guide enables the cement pile to be quickly and stably positioned in the pile driving mechanism, thereby greatly improving the pile driving efficiency.
