Description

Technical Field

[0001] The utility model relates to the technical field of foundation engineering equipment, in particular to a rail-following gooseneck hammer. Background Art

[0002] During the piling process, the hammer body breaks the stones in the soil, and squeezes the crushed stones to the side of the pile through the impact force to form a soil-rock retaining wall. However, if encountering inclined stones at special positions, they cannot be broken after multiple impacts. Then, it will cause the hammer body to be tilted or deviated by the inclined stones. And the hanging ears and the rail-following device at the top of the hammer body are connected to the guide rail and are relatively fixed. Then, it will cause the destructive separation of the hammer body and the hammer handle, or pull, push and deform or damage the rail-following device (including the track), and it is necessary to separately increase the working hours for re-hanging the hammer and the repair link, which affects the construction safety and efficiency. On the second hand, if the hammer body is tilted and the hammer body has entered the soil, under the clamping action of the crushed stones and soil, the pulling-up ability of the lifting equipment of the hammer body will be greatly weakened, and it may also cause damage to the main equipment, thus increasing the safety hazards and maintenance costs again and delaying the construction period.

[0003] In view of this, we propose a rail-following gooseneck hammer. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a rail-following gooseneck hammer.

[0005] The technical solution of the utility model is: including a hammer body, characterized in that: a hanging head is arranged at the top of the hammer body, and the hanging head realizes the connection of the hammer body or the small hammer tube and the large hammer tube therein through a gooseneck connection section by using a universal micro-expansion hole connection mechanism, and a stone-breaking mechanism is installed at the bottom of the hammer body.

[0006] As a preferred technical solution, a large hammer tube is arranged at the bottom of the small hammer tube.

[0007] As a preferred technical solution, the bottom of the large hammer tube is connected to the main rod section.

[0008] As a preferred technical solution, one or more adjustment sections are connected to the bottom of the main rod section.

[0009] As a preferred technical solution, the stone-breaking mechanism includes a base.

[0010] As a preferred technical solution, one or more conical hammer heads are installed on the base.

[0011] As a preferred technical solution, a conical handle is arranged at the top of the base and is clamped with a cross pin in the bottom groove of the hammer body and is further fixed by a pin on both sides, and a conical sleeve is arranged outside the conical handle.

[0012] As a preferred technical solution, the universal micro-expanding hole connecting mechanism includes an upper seat, a lower seat, and a main rod. One end of the main rod is connected to the lower seat through a connecting rotating shaft by means of a clamping plate. The other end of the main rod is connected to the upper seat through a main pin and a secondary pin. The upper seat is further fixed by a rib plate around the main rod. The upper seat is fixedly connected to the hanging head or the gooseneck connecting section. The lower seat is fixedly connected to the gooseneck connecting section or the small hammer tube. As a preferred technical solution, the number of gooseneck connecting sections is one or more.

[0013] As a preferred technical solution, the bottom of the adjusting section is connected to the connecting hammer head section, and the connecting hammer head section is used to connect the stone-breaking mechanism.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Through the connection of the universal micro-expanding hole connecting mechanism at both ends of the gooseneck connecting section with the hanging head and the hammer body or the small hammer tube therein, flexible connection is achieved through the "universal micro-expanding hole connecting mechanism". During the drilling operation, especially when the hammer bottom touches large-diameter boulders or hard objects, the upper end of the gooseneck-shaped hammer will naturally produce a certain degree of (front-back or left-right) micro-swing. The "universal joint" function leaves a certain amount of movement space for this swing, forming a flexible connection effect. It can not only eliminate the adverse factors (causing hard collisions with the pile driver track and corresponding distortions and damages) generated by the rigid connection between the original pile driver track and the gooseneck-shaped hammer, but also achieve a certain degree of micro-expanding hole effect that gradually increases from bottom to top for the pile hole.

[0016] 2. By setting a stone-breaking mechanism at the bottom of the hammer body, conical hammer heads of different shapes can be installed according to actual needs to meet the construction requirements of different sites. When it is difficult to complete the crushing operation with one conical hammer head for the stones, one cone head can first touch the bottom to break the stone, and the others can follow up to deal with the influence of the tilted hammer for large inclined boulders. It can not only solve the problem of large inclined boulders that are difficult to break, but also greatly reduce the frequency of machine breakdown and improve the construction efficiency.

[0017] 3. The bottom stone-breaking mechanism is connected to the bottom of the hammer body through a transverse pin at the top of the base and a taper shank, which is convenient for quick disassembly and greatly improves the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment 1

[0028] Please refer toFigure 1 , 3 , 5. The present utility model provides a technical solution:

[0029] A track-aligned gooseneck sledgehammer, including a sledgehammer body 1.

[0030] A hanging head 5 is provided at the top of the sledgehammer body 1, and the hanging head 5 is used for lateral connection with the pile driver track.

[0031] The hanging head 5 is connected to the sledgehammer body 1 or the small sledgehammer tube 3 therein through a gooseneck connection section 4 by means of a universal micro-expansion hole connection mechanism 6.

[0032] In this embodiment, a large sledgehammer tube 2 is provided at the bottom of the small sledgehammer tube 3.

[0033] In this embodiment, the bottom of the large sledgehammer tube 2 is connected to the main rod section 8.

[0034] In this embodiment, the bottom of the main rod section 8 is connected to one or more adjustment sections 9.

[0035] In this embodiment, the bottom of the adjustment section 9 is connected to a connection hammer head section 10, and the connection hammer head section 10 is used for connecting the stone-breaking mechanism 7.

[0036] It is further worth noting that the small sledgehammer tube 3, the large sledgehammer tube 2, the main rod section 8, and the adjustment section 9 are all connected by welding, and there are reinforcing ribs on the side for further fixation.

[0037] In this embodiment, the universal micro-expansion hole connection mechanism 6 includes an upper seat 601, a lower seat 602, and a main rod 603. One end of the main rod 603 is connected to the lower seat 602 through a connecting rotating shaft 604 by means of a clamping plate 605. The other end of the main rod 603 is connected to the upper seat 601 through a main pin 606 and a secondary pin 607. The periphery of the main rod 603 further fixes the upper seat 601 through a rib plate 608. The upper seat 601 is fixedly connected to the hanging head 5 or the gooseneck connection section 4, and the lower seat 602 is fixedly connected to the gooseneck connection section 4 or the small sledgehammer tube 3.

[0038] In this embodiment, the number of the gooseneck connection sections 4 is one or more.

[0039] It is further worth noting that the number of the gooseneck connection sections 4 can be one or more according to the construction needs, and universal micro-expansion hole connection mechanisms 6 are provided at both the top and the bottom of the gooseneck connection section 4.

[0040] It is further worth noting that a flexible connection is achieved through the "universal joint" to form a "gooseneck" function. During the driving process, especially when the bottom of the hammer touches large-diameter boulders or hard objects, the upper end of the track-type rammer will naturally produce a certain degree of (front-back or left-right) micro-swing. The function of the "universal joint" can leave a certain amount of room for this swing, forming a gooseneck function and achieving a flexible connection effect. This not only eliminates the adverse factors (causing hard collisions with the pile driver track and corresponding distortions and damages) generated by the rigid connection between the original pile driver track and the track-type rammer, but also can achieve a certain degree of micro-hole expansion effect that gradually increases from bottom to top for the pile hole.

[0041] A stone-breaking mechanism 7 is installed at the bottom of the rammer body 1.

[0042] In this embodiment, the stone-breaking mechanism 7 includes a base 701.

[0043] In this embodiment, one or more conical hammer heads 702 are installed on the base 701.

[0044] When performing a single extrusion and impact operation, a conical hammer head 702 is installed on the base 701 using bolts, and during the construction process, it can quickly break and crush stones, accelerating the hole-drilling operation.

[0045] Embodiment Two

[0046] As Figure 2 shown, in the case where it is difficult to complete the crushing operation with a single conical hammer head when encountering an inclined surface or a large side-standing boulder, multiple conical hammer heads 702 can be installed on the base 701 by bolts or welding, so that one conical head touches the bottom first to break the stone, and the others follow up to cope with the influence of the tilted hammer caused by the inclined surface large boulder. This can not only solve the problem of large inclined surface boulders that are difficult to break, but also greatly reduce the frequency of machine failure and improve the construction efficiency.

[0047] Embodiment Three

[0048] As Figure 4 shown, a stone-breaking mechanism 7 is installed at the bottom of the rammer body 1.

[0049] In this embodiment, the stone-breaking mechanism 7 includes a base 701.

[0050] In this embodiment, a taper shank 703 is provided at the top of the base 701 and is clamped with a cross pin 704 at the bottom of the rammer body 1 and further fixed by a cotter pin 705 on both sides.

[0051] A taper sleeve 706 is provided outside the taper shank 703.

[0052] Among them, a groove is provided at the bottom of the hammer body 1, that is, the connecting hammer head section 10. A cross pin 704 is horizontally arranged in the groove. The taper shank 703 fixedly connected to the top of the base 701 can just be inserted into the center of the cross pin 704. The cross pin 704 is clamped with the taper shank 703, and then further fixed by the locking pins 705 on both sides of the cross pin 704, realizing the connection between the stone-breaking mechanism 7 and the hammer body 1. And the taper shank 703 can be pulled out from the cross pin 704 to complete the disassembly of the stone-breaking mechanism 7, and the corresponding taper head can be replaced at any time according to different geological requirements.

[0053] This mechanism realizes rapid disassembly, changes according to different construction requirements, and greatly improves the construction efficiency.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
