Description

Technical Field

[0001] The utility model relates to the technical field of vibro-compaction equipment, in particular to vibro-compaction equipment for water conservancy foundation engineering. Background Art

[0002] Vibratory impact equipment uses horizontal vibration force to vibrate the filler and surrounding soil, thereby compacting the foundation, which is beneficial to improving the bearing capacity of the foundation, reducing the amount of settlement, increasing the stability of the foundation, and improving the ability to resist earthquake liquefaction. The patent number is "CN219710269U", and the patent name is "A utility model patent for vibratory impact equipment for water conservancy foundation engineering", including a vibrator body, the outside of which is equipped with a vertical positioning tube, and the inside of the vertical positioning tube is provided with a plurality of limiting mechanisms, and the limiting mechanism includes an adjusting screw, a transmission frame, and a limiting roller, and the outside of the vertical positioning tube is provided with an adjusting leg mechanism with the same number as the limiting mechanism.

[0003] However, the above-mentioned vibroflotation equipment still has certain disadvantages in certain usage situations: on the one hand, the above-mentioned vibroflotation equipment adjusts the vertical positioning tube to a vertical state by setting a vertical positioning tube on the outside of the vibroflotation body. In actual applications, the overall volume of the vibroflotation body is relatively large. If the vibroflotation body needs to be fixed, a leg mechanism of a matching size is required, which makes it inconvenient to rotate and adjust the leg mechanism, and it is inconvenient to install, and the overall structural design is unreasonable. On the other hand, when the vibroflotation equipment is working, the vibroflotation body is always in a vibrating state, and the limiting mechanism is in rigid contact with the vibroflotation body. The limiting mechanism will become loose and unreliable under long-term working conditions. Therefore, a vibroflotation equipment for water conservancy foundation engineering is proposed to solve the above-mentioned defects in a targeted manner. Summary of the invention

[0006] In a preferred embodiment of the utility model, a fixing collar is arranged on the outer circumferential side of the hydraulic telescopic column, and the outer circumferential side of the fixing collar is hingedly connected to two push-pull rods, and the other ends of the two push-pull rods are respectively hingedly connected to the arc-shaped clamping plates.

[0007] In a preferred embodiment of the utility model, a slot is provided on the outer peripheral side of the hydraulic telescopic column, the fixing collar is cooperatively connected with the slot, and the two push-pull rods are symmetrically provided on the outer peripheral side of the fixing collar.

[0011] The utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0012] (1) The utility model fixes the limit mechanism at a specified position through a hydraulic telescopic column. The bottom end of the vibrating head and the limit mechanism are located in the same horizontal projection plane, which effectively ensures that the vibrator is always in a vertical state and improves the foundation quality.

[0020] like Figure 2 and Figure 3 As shown, the limiting mechanism includes: a hydraulic telescopic column 2 horizontally arranged at the front end of the lifting equipment, the hydraulic telescopic column 2 is connected to the assembly block 4 through a piston rod 3, the upper and lower ends of the assembly block 4 are integrally provided with a pin shaft 5, and both sides of the pin shaft 5 are hingedly connected to an arc clamping plate 6. The limiting mechanism is fixed at a specified position by the hydraulic telescopic column 2, and the bottom end of the vibrating head 102 and the limiting mechanism are located in the same horizontal projection plane, which effectively ensures that the vibrating head is always in a vertical state, thereby improving the foundation quality.

[0021] In a preferred embodiment of the utility model, a plurality of guide rollers 7 are arranged in an array on the inner side of the arc-shaped clamping plate 6, and the outer peripheral side surface of the guide roller 7 is set as an arc-shaped concave surface, and the guide roller 7 cooperates with the outer peripheral side surface of the vertical guide rod 101. Through the guide roller 7, the limiting mechanism and the vertical guide rod 101 can be better coordinated with each other, and the outer peripheral side surface of the guide roller 7 is set as an arc-shaped concave surface, which further enhances the stability of the guide roller 7 when cooperating with the vertical guide rod 101 and improves the foundation quality.

[0022] In a preferred embodiment of the utility model, a fixing collar 8 is provided on the outer side of the hydraulic telescopic column 2, and two push-pull rods 9 are hingedly connected to the outer side of the fixing collar 8, and the other ends of the two push-pull rods 9 are respectively hingedly connected to the arc-shaped clamping plate 6. A slot is provided on the outer side of the hydraulic telescopic column 2, and the fixing collar 8 is connected with the slot, and the two push-pull rods 9 are symmetrically arranged on the outer side of the fixing collar 8. When the hydraulic telescopic column 2 is retracted, the piston rod 3 drives the assembly block 4 to approach the fixing collar 8, and the two push-pull rods 9 push the two arc-shaped clamping plates 6 to close. When the hydraulic telescopic column 2 is extended, the piston rod 3 drives the assembly block 4 away from the fixing collar 8, and the two push-pull rods 9 pull the two arc-shaped clamping plates 6 to open. Through the extension and contraction of the hydraulic telescopic column 2, the opening and closing of the annular clamping plate is controlled, so that the arc-shaped clamping plate 6 stably clamps the vertical guide rod 101, which is more convenient for installation and adjustment.

[0024] The working principle of the utility model is as follows: in the initial state, the hydraulic telescopic column 2 is in an extended state, at this time, the two arc-shaped clamping plates 6 in the limit mechanism are opened, and after the vertical guide rod 101 is lifted by the lifting chain 12, the vertical guide rod 101 enters between the two arc-shaped clamping plates 6, the hydraulic telescopic column 2 contracts, and the piston rod 3 drives the assembly block 4 to approach the fixed collar 8.
