Problems solved by technology

[0004] The chiseling device in the prior art has the following disadvantages when it is used: the chiseling device uses a crushing mechanism to crush the pile head, and it needs to use a crane to continuously lift the device during operation, which greatly increases the difficulty of construction and cost, in addition, it is impossible to achieve multi-angle and height chisel operation on the pile head, and the efficiency is low. Therefore, the present invention proposes a flexible adjustable pile head chisel removal device for pile foundation construction.

Embodiment 1

[0037] refer to Figure 1-6 , a flexible adjustable pile head cutting device for pile foundation construction, including a base ring 2 and a ring body 3 sleeved on the outside of the pile head 1, and a base ring 2 and a plurality of rings are sleeved on the outside of the pile head 1 body 3, the base ring 2 is located on the lower side of the ring body 3, the base ring 2 and the ring body 3 are in a detachable sliding connection, and the ring body 3 and the ring body 3 are in a detachable sliding connection.

[0038] Such as Figure 2-4 As shown, an annular slide rail 12 is installed on the top of the base ring 2 and the ring body 3, and the bottom of the ring body 3 is provided with an annular groove 13. The base ring 2 and the ring body 3 can be moved through the annular slide rail 12 and the annular groove 13. Separate sliding installation, the ring body 3 and the ring body 3 are detachably slidingly installed through the annular slide rail 12 and the annular groove 13 . ...

Embodiment 2

[0052] refer to Figure 7-8 In this second embodiment, on the basis of the first embodiment above, a plurality of crushing motors 21 are installed on the outside of each ring body 3 at equal intervals. rod 22. The breaking rod 22 is spaced apart from the pneumatic pick 10 .

[0053] In this embodiment, four air picks 10 and four crushing motors 21 are arranged on the outside of each ring body 3 , and the driving ends of the crushing motors 21 are equipped with crushing rods 22 extending to the inside of the ring body 3 .

[0054] The crushing motor 21 drives the crushing rod 22 to rotate, and the crushing rod 21 is used to crush the concrete block produced when the pneumatic pick 10 is cut through the pile body 1, so that it becomes a small concrete block and falls on the bottom of the base ring 2. At this time, it is convenient to remove and transport the concrete block.

Abstract

The invention discloses a flexibly adjustable pile head chiseling device for pile foundation construction, and belongs to the field of building machinery. The flexibly adjustable pile head chiseling device comprises a base ring and a plurality of ring bodies, the base ring and the ring bodies sleeve the outer side of a pile head, the base ring and the multiple ring bodies sleeve the outer side of the pile head, the base ring is located on the lower side of the ring bodies, the base ring is in separable sliding connection with the ring bodies, the ring bodies are in separable sliding connection, a plurality of punched holes are formed in the ring bodies in a penetrating mode, and double-face gear rings are fixed to the outer sides of the ring bodies. The flexibly adjustable pile head chiseling device is formed by vertically splicing and assembling the base ring and the multiple ring bodies, the pile head is chiseled through an air pick with the adjustable angle and position, and the number of the ring bodies is set according to the height of the pile head, so that the pile heads with different heights are chiseled; an impact drill bit of the air pick can be buffered in the chiseling process, the damage probability of the air pick is further reduced, and the service life is prolonged; and in addition, concrete blocks can be crushed in the chiseling process, and the concrete blocks can be conveniently cleared and transported.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a flexibly adjustable pile head chipping device for pile foundation construction. Background technique [0002] The principle of chiseling the pile head is that during the concrete pouring process of the pile body, due to the rise of the air bubbles or pores inside the concrete to the top of the pile, a certain range of the top of the pile is laitance, or the mud and mortar mixture when pouring underwater concrete. In order to ensure the concrete strength of the pile body, the upper virtual pile must be chiseled out. [0003] After retrieval, Chinese Patent No. CN 212129137 U discloses a device for crushing and removing pile heads of bridge pile foundations. The bridge pile foundation pile head crushing and removing device includes a support mechanism; a crushing mechanism; a hanging ring; a connecting mechanism, the connecting mechanism is installed on the side w...
